Answers to the Mah Nishtanah

Question: Almost every small Jewish child learns the Mah Nishtanah sometimes even in multiple languages the questions remains is that the question remains. Where in the Haggadah are the four questions answered (please do not tell me "Ha Lach Mianya" and if you do please tell me how it does) where in the Haggadah do we find direct  answers to the questions asked? any article or your own answer would be appreciated!
Comment: Did you mean "Ha Lachma Anya" or "Avadim Hayinu" when saying "please don't tell me..."? Because i've often heard the second given as a simple answer, but never the first.

Comment: leaning and Dipping?
Comment: Are you asking me? Leaning isn't mentioned in the Ma Nishtana. Dipping as I mentioned there is the question about Maror.
Comment: there are readings that have these 4 statements as answers to "how is this night different" and others that say that they are simply rabbinic and Torah examples as expanding on "why is this night different" which is answered by the maggid section which explains the specialness of the night - epitomized by avadim hayinu. So they might not be viewed as discrete questions requiring specific answers.
Answer: I'll deal with one potential aspect of your question, and hopefully others will be able to add more: to what extent are the questions in Mah Nishtanah answered within the text of Mah Nishtanah itself? This issue is discussed at length by Prof. Richard C. Steiner of Yeshiva University, in an article titled, "On the Original Structure and Meaning of Mah Nishtannah and the History of its Reinterpretation" (JSIJ 7 [2008], 163-204). The article can be read online here, and I summarise it below.
There are at least three different ways of construing the number of questions in the Mah Nishtanah, at least one of which provides answers. The differences in interpretation boil down to three different ways of construing the word mah (מה), and three different ways of construing the particle she- (ש). Those different interpretations are as follows:
1) Mah (מה) = "What?"; she- (ש) = "[such] that".

"What differentiates this night from all other nights, such that
  [examples A, B, C, D]?"

This interpretation of the two lexemes (mah and she-) has great precedent, and elicits a reading of the text in which there is a single question: what is it about this night to have produced these four differences between it and all others?
2) Mah (מה) = "Why?"; she- (ש) = "for".

"Why is this night different from all other nights? For, [examples A?
  B? C? D?]"

This is the best attested interpretation of the text, although it too can be understood in three different ways:

Four questions: why is this night different in respect of example A? In respect of example B? In respect of example C? etc;
Five questions: Why is this night different from all other nights? Why do we do example A? Why do we do example B? etc;
One question, and four answers: Why is this night different from all other nights? Because of example A, because of example B, because of example C and because of example D.

3) Mah (מה) = "How!"; she- (ש) = "for" (idiomatically, "why")

"How different this night is from all other nights! Why, [examples A!
  B! C! D!]"

This interpretation also has some precedent, though it yields a reading of the text in which there are no questions, being a rhetorical assertion only, and therefore one in which it also requires no answers.
The only construals of the text that require an answer are those found in interpretation 1 (a single question), interpretation 2.1 (four questions) and interpretation 2.2 (five questions). Where the first (1) asks about the general nature of the evening, and the second (2.1) about the specific things that we are doing, the third (2.2) combines them both together. You might suppose that the entirety of the haggadah is an answer to that first question, while the second (why do we do examples A, B, C and D?) is answered more specifically at various junctures within it.
Fascinatingly, the 1609 Venetian Haggadah was printed with three different translations: Yiddish, Judeo-Italian and Judeo-Spanish. All three of these translations rendered the mah (מה) in Mah Nishtanah differently:
Yiddish: וואז ("What?");
Judeo-Italian: פַיר קַי ("Why?");
Judeo-Spanish: קואנטו ("How!").
I encourage you to read Prof. Steiner's full article, which is considerably more thorough than what I have presented here.
Comment: This and another answer of yours have now been published in *Hagada - Mi Yodeya?* Second Edition: http://s.tk/miyodeya. Thanks!
Answer: The Maharal in Gevuros Hashem Ch. 52 suggests two answers to this question:
First answer:

דודאי התשובה הוא בסוף המאמר שמשיב על פסח מצה ומרור כאשר מגיע לשם... וכן על שאנו מסובין משיב בכל דור ודור חייב אדם לראות את עצמו כאלו הוא יצא ממצרים וכו' ומפני שיראה עצמו כאילו יצא ממצרים יש לעשות הסבה
The answer is at the end in the description of the Pesach sacrifice, matzah, and marror, when he gets there... and that which we lean is answered in the paragraph in which we declare that in every generation one must see one's self as if he himself left Egypt, and therefore he should lean

Second answer:

כי מה נשתנה שאלת חכם... ויודע הוא זה... אלא ששואל מה ענין זה לנו כי מה קרה לנו ... ומתרץ עבדים היינו לפרעה
Mah Nishtana is the question of a scholar... and he understands the meaning of all of these things... rather he is asking what does this have to do with us, and what happened to us... and the answer is "we were slaves to Pharaoh etc."

I skipped the supports that he brings to his idea, but you can see it here.
Comment: This answer has now been published in [*Hagada - Mi Yodeya* Second Edition](http://s.tk/miyodeya). Thanks!
Comment: @IsaacMoses Woohoo!
Answer: Rabbi Yosef Yitzchok Katz in a sefer called Haggadah KeHalachah (p. 282) explains that all the questions are answered in the first paragraph, as subsequently expounded in the Haggadah.
ויוציאנו ה' משם - G-d took us out from there, which was in a way that there was no time for the dough to rise, so we only eat Matzah.
עבדים היינו - We were slaves, and the Egyptians embittered our lives during that slavery, so we eat bitter herbs.
ביד חזקה - With a strong hand, meaning that we are free today, so we lean like free people.
Regarding dipping he says that the only questions the Haggadah answers are those that address the specific practices for the seder night, not those that the child was taught to say but that he didn't observe. The only dipping he observed so far was Karpas which was only so that he should ask.
[Presumibly he means that the Matza and Morror he observes with Yachatz and on the Seder plate.]
He then brings the Abarbanel's answer (Zevach Pesach on Avadim HaYinu) that the answer is that tonight we are making a remembrance for two times in the life of our forefathers in Egypt. At the beginning of the night, we were slaves, therefore we do remembrances of slavery - the Matzah and the Morror. Then Hashem took us out, so we dip twice and lean while eating to commemorate the freedom.
Answer: The first two questions (assuming that we consider the 1st question to be the one about matzah, and the 2nd about maror) are answered quite directly just after the "Rabban Gamliel" section/ It explains why we eat matzah; another paragraph why we eat marror.
Offhand, I don't know where the hagadah answers directly the last 2 questions about dipping & reclining.
Comment: I guess thats the focus of my question
Answer: Dipping can be associated with the splitting of the sea (in Hallel), while reclining can be associated with the four cups of wine.

Answers to the Mah Nishtanah


Smoking and its effects on muscle building

Question: Does smoking effect the muscle building process? I understand it can effect your endurance.
Comment: Entirely anecdotal, but I smoked a pack a day, and swam on a master's swim team, deadlifted 2x bodyweight, and could run a 6 min mile. That being said, you're better off without it, as long as quitting doesn't make you depressed and kill your motivation. I quit using the patch + zyban + a few days of nicotine lozenges
Answer: In my experience, the most detrimental aspect of smoking while bodybuilding is the lack of energy.
When I smoked, I was quite lethargic most of the time and in gym I used to just quit whenever it got too hard, or took too much energy.
Since I didn't feel fresh or rejuvinated even after a good nights sleep, going to the gym was usually out of the question, because I just didn't feel like it.

From a medical standpoint, probably the most detrimental aspect of smoking is lack of oxygen. Whilst smoking, the oxygen intake is lessened and it is replaced by various other elements, usually, ones bad for the body.
Also, the toxins that the cigarettes contain may lead to various diseases, in which case, doing serious weight training is probably out of the question.
Standard Disclaimer:
I am not a doctor, so anything I say should not be considered an advice to bet your health on.
Answer: Good Question.
Not to direct you away from StackExchange, but Bodybuilding has the answer.
I'll just copy over the ones related to muscle building and fitness:

Increase in heart rate

Increase in hormone production
Increase in blood pressure
Constriction of small blood vessels on skin
Changes in blood composition
Changes in metabolism

In the spirit of positive thinking,
  here are the benefits of quitting:

Breathing improves
Improved ability to cope with sudden    exertion
Loss of smokers cough and reduction    of phlegm
Sense of taste and smell improves
Natural decline in lung efficiency    slows down to a rate similar to
  nonsmokers
Reduced risk of smoke related    diseases

I'd say the increase in heart rate, and the incremental damage to the lungs will be most problem.
Answer: Also keep in mind that nicotine acts as a coronary vasoconstrictor and increases insulin resistance. I imagine the decreased blood flow might adversely effect your cardiac output despite the increased rate, or likely reduce your total potential cardiac output. I know it also does some peripheral vasoconstriction, potentially in muscle cells, the extent to which that is overcome by the metabolic hyperemia that comes with weight training but there is a good chance you're forcing your muscle cells into switching to anaerobic energy metabolism early than they should. (thus reducing force of contraction)
Also, decreasing insulin sensitivity is a bad thing if you are trying to put on muscle. Just ask any of those bodybuilders who inject the stuff. It is an "anabolic" hormone.
The improvement in lung function is probably more important than all the other stuff I just mentioned. Better lung function = better oxygenation to muscles during exercise = increased output
Buyer beware, I'm not a physiologist, and it's been a while since I studied it formally.
Answer: Of all the destructive habits that anyone can have, smoking is considered the worst. Almost all organs of the body are affected by the action of toxic compounds from cigarette. Learn how they can seriously harm your gains in the gym and why you should use this as an incentive to quit smoking.
If you are targeting a remarkable change in the composition of your body, you better get used to the idea of quitting sooner. Smoking may be more harmful than using other drugs like alcohol and marijuana, for those who train with weights. Learn why:
1 - Smoking causes irreversible damage to the respiratory system
Damage to the respiratory system have a direct connection with the performance within the academy, either weights or cardio. The damage caused by smoking, causes the body can not absorb oxygen into the blood, affecting muscle oxygenation, ie you do not get to train with the same intensity that a person can not smoke.
2 - The heartbeat of a smoker is 30% faster than a non smoker.
This forces the body of a smoker to expend more energy than usual. This acceleration in heart rate is due to the stimulating effect of nicotine, the resulting change in blood pressure is paradoxically decreases the flow of blood in vessels, which consequently reduces the physical performance.
3 - Smokers produce twice phlegm
The change can disrupt production of phlegm in breathing that can affect physical performance. The habit also causes a chronic swelling in the mucus glands that can frame the problem worse.
4 - Smoking significantly reduces oxygen available for muscles
Carbon monoxide present in the cigarette has a higher affinity for hemoglobin (a molecule that carries oxygen in the blood) than oxygen itself. The act of smoking encourages the body to exchange oxygen for carbon monoxide, causing less oxygen is available to the muscles which in turn will also affect performance.
conclusion
Smoking is clearly a destructive habit. It is difficult to understand why someone starts to smoke, knowing all its evils, especially for those who train with weights attached and the quality of the body.
It is extremely difficult to stop smoking, aiming to build muscle mass and try to always take the body beyond the limit itself is the perfect inspiration to drop this destructive hábido forever. Think about it!


Starcraft 2 Macro Cycle

Question: I've just started to learn the macro style. It's really disrupting my play style - any tips on learning how to use this style of play?
Comment: [This question](http://gaming.stackexchange.com/q/2900/3107) has [an answer](http://gaming.stackexchange.com/a/3039/3107) that may help you out. :)
Answer: Day[9] has lots of dailies where he talks about specifically this or more generally about learning any particular thing. Well worth a look.
His main point is to get comfortable with losing games where you are training since you aren't training for the five games today but the fifty games after today.
One example for practicing your macro would be to play five games in a row where ALL that you are focusing on is constantly building workers, never being supply blocked and always having low money (or even just one thing!). If during these training games you get attacked - don't worry, just keep focusing on those three things and deal with the attack only if it doesn't break that focus - EVEN if it costs you a game!
The idea is that these training games with a dedicated focus should make the things you are training second nature, so that afterwards you don't even need to think about them.
Answer: Macro play is the foundation of SC2.
After you know how to handle macro then you can get fancy and cheesy.
Because if your cheese fails, you need to be able to move on and recover!
There's a lot of variables: Observer your opponent, is he mounting an attack? No. Expand!
Try to expand every 5 minutes and build workers. Keep observing your opponent. If he is mounting an attack, prepare some defense and get ready but don't over do it.
A few minutes later, you get so much money you won't even know how to spend it. The key at this point is to know how to macro your production. (put a shortcut on those barracks on those queens, on those gateways!)
If you have good macro, you will climb the later pretty well.
Answer: Just put a sticky note at one side of your screen with:

Worker
Supply
Units
(upgrades)
(watch minimap)
rinse and repeat

Repetition is everything, at some point it becomes natural.
Comment: Put the watch minimap on the top ..

How to use entity reference field titles in Views exposed and combined filters

Question: I have two content types: Institution and Contact.
Any number of Contacts are associated with any number of Institutions.
Contacts are associated with Institutions via an Entity Reference field.
I have a view defined as follows:
Format: Show: Fields
Content: Published (Yes)
Content: Type = (Institution)
Content: Title (exposed)
Content: Contact (exposed)
Combined: Titles and Contacts (exposed)
The current sticking point is the exposed filter for Contact (an Entity Reference) requires the integer value of field_data_field_contact.field_contact_target_id, which frontend users have no means of knowing. I need a way of translating a Contact node's Title to the target ID transparently, and this method must also be accessible to the combined field Titles and Contacts.
Result sets for contacts are in the thousands, so providing a dropdown to the view is not workable.
The view type is likely set in stone, because it has been in production for years and has a great many fields.
Answer: You just need use Views Reference Filter module


Blogger invitation limits

Question: I have a blog on Blogger. I want to keep my blog private, but I have more than 100 invitations I want to send. Can you suggest what I could do? I don't want a public blog that anyone can access just by web search or people passing on my blogspot address.
Comment: http://webapps.stackexchange.com/q/31205/354
Answer: You've hit a hard limit here.   You can have a public blog or a private one.   If you have a private one, you can send up to 100 invitations to people to read it.
Your only option would be for some readers to share the same password - but this would annoy them if they had to sign out of their own Google account and into the shared one to read.   And if you don't trust people not to share your blog address, then you probably don't trust them not to share the account/password.

Css file erases new editing

Question: When I add new styles to the template.css, Joomla doesn't save them for a long time it keeps resetting the code. although the html code keeps the new lines that I add.
Why is this happening!!
Answer: This can be for one of this possible reasons:

Your template uses some framework, like T3 or Helix, and you have enabled a feature that allows you to compile the code every time the page is reloaded.
Solution 1:
Check if you have this option enabled in Templates > Your Template
Solution 2: Some template frameworks allows you to add another css file called custom.css or similar, in this way you can add your code that replaces the general css.
You are trying to replace the css code of an extension as a module, normally these files are added below the related template, this works similar to:
your_site/.../general.css
your_site/.../template.css
your_site/.../preset.css
your_site/.../custom.css
your_site/.../module1.css (in the cascade, this file override all the previous css code)
Solution 1: Also, some templates allows you to add your custom code in Templates > Your Template, check if you have this feature.
Solution 2:  Add your custom css in your custom.css file and check the specificity, if you only have a few css rules you can use !important.
Solution 3: Change the code directly in the extension.

Also you can add your custom css vía extensions, but try with any of the above solutions:
http://extensions.joomla.org/extensions/extension/style-a-design/templating/cssconfig http://extensions.joomla.org/extensions/extension/style-a-design/templating/css2switch-basic

You can use a tool like Firebug for inspect the source code of your page in your browser, this will help you to save a lot of time.
Answer: You didn't specified if this is happening during saving or right after it, or if your custom.css rules remain untouched until you perform an update to Joomla or your template.
If you fall into the first case, I don't have an answer at hands right now. But for the the second case what you see happening is absolutely normal.
Golden Rule: Never, ever modify core files (if you want to maintain your customizations). That's because each update will replace core files, resulting in loss of your modified ones.
Joomla and most of the commercial templates provide the ability to create overrides. This is how you have to approach this, in order to add your own custom css.
This question for css overrides will give you a good ground for what you need to do: How do I override the CSS styles in my template?
There are also extensions that allow this, if you can't find other ways.

http://extensions.joomla.org/extension/add-custom-css
http://extensions.joomla.org/extension/custom-css
Answer: Probably every time you update Joomla, you the template.css file gets updated and with a news version and you lose the changes you made.
The correct way to customize your Joomla website is using template overrides. This way you do not modify the Joomla core files, and your changes will never get overriden.

Where can I look up a companies Herfindahl index?

Question: Where can I find Herfindahl indexes on companies (current or past)? Are there any published lists put out by a research institution?
Comment: Also I don't have enough karma to add the correct tags to this question.
Answer: HHI index cannot by definition be on companies. It is the squared sum of market shares of all the companies in a country. So, if you are looking for companies' market shares, you should look at each country individually.
But if you want HHI index on countries (which is a correct way of framing the question) then you can use this WorldBank data: https://tcdata360.worldbank.org/indicators/hh.mkt


How does NASA get information from space probes?

Question: So I have briefly gone over answers to how things are stored as from this answer: https://space.stackexchange.com/a/2273/1247 but how is the information sent back? I'm thinking of probes like the Voyagers, the Pioneers, the Mars probes and Hubble.
Comment: If anyone wants to include this link in their answer, I think it's rather cool: http://eyes.nasa.gov/dsn/dsn.html :)
Answer: Mostly it's by radio waves.
Some "information" is physically transported back to Earth. The Apollo missions brought 382 kg of lunar samples back to Earth and the Soviet Union Luna program brought 0.326 kg of lunar samples back to Earth. That kind of return is highly valuable information. Even with the success of the Mars rover programs, a Mars sample return mission would still provide very useful insight into the geology of Mars.
Recently NASA has experimented with using lasers instead of radio communications. The much higher frequencies associated with laser communication have the potential of a much higher communications rate. The Lunar Laser Communication Demonstration on the Lunar Atmosphere and Dust Environment Explorer achieved a 622 megabits per second downlink rate. That's orders of magnitude higher than the rate achievable with radio waves.
Update regarding latencies:
The speed of light dictates the latency for vehicles well beyond the Earth such as the rovers at Mars and the New Horizons vehicle en route to Pluto. The one-way travel time between New Horizons and Earth will be around 4.5 hours when the vehicle flies by Pluto. Commands need to be sent at least 4.5 hours in advance, making for a 9 hour delay between sending a command and receiving the vehicle's response to the command.
For vehicles in low Earth orbit such as the ISS and the Hubble, speed of light is but a small part of the communications delay. Watch a NASA video where mission controllers talk with the astronauts aboard the ISS. There's about a good four or five second delay, even for simple questions such as "ISS crew, are you go?" The one way travel time between low Earth orbit (or Earth surface) and geosynchronous orbit is about a quarter of a second. Double that and you get half a second for round trip light delay.
So where does that extra four seconds or so come from? The answer is bits bouncing around inside and between computers. The mission controller's "are you go?" query is digitized, mixed with other signals to be sent to the ISS, and transmitted via ground links to White Sands. The signal enters White Sands at the NASA Ground Terminal, where it is mixed with other signals that will eventually be sent to the appropriate Tracking and Data Relay Satellite. The signal constructed by the NGT next makes a short hop to the White Sands Ground Terminal, which does even more data manipulation. The signal is next send to an antenna and transmitted to the TDRS. The signal arriving at the TDRS has to be split into component parts, another computer at work. That signal is sent to the ISS, where it goes through yet another computer before the crew hear it. The entire process is reversed when the crew reply "Go!" to the query.
Comment: Film used to be returned to Earth from many spy satellites, it's pretty uncommon now, but...
Comment: About the latencies, radio waves travel with the speed of light, so over greater distance there will suddenly be larger communications delay. For Mars, the delay will be between 3-20 minutes.
Answer: As David said, probes generally communicate via radio. Long-range space probes often carry a dish antenna.
A parabolic dish antenna focuses the signal into a narrow cone. Compared to a standard wire antenna that transmits evenly in all directions, a dish makes sure as much of the signal as possible is sent in the direction of the receiver.
This gives the strongest radio signal possible within the limited power budget of the probe.
For space probes that aren't in Earth orbit, NASA operates the Deep Space Network (DSN): a series of large dish antennas designed to receive the very weak radio signals from far-away space probes. They can still communicate with the Voyager probes on the other end of the solar system.
For Mars ground missions, the rover or ground station often communicates with an orbiter. The orbiter relays the signal to Earth.
When you use a dish antenna on Earth, you can make it very large, in order to gather more of the signal. The larger the dish, the weaker the signals it can pick up.
As the last step, the receiver on Earth is very sensitive. The receiver is often cooled to very low temperatures to reduce noise.
As a result, this chain (transmitter with dish antenna, sensitive receiver with large dish antenna) can pick up a 10 W transmitter from 100 AU away.
You can find more details in these related questions:
Communication with Voyager
DSN operations
Hubble is close enough that it doesn't need the DSN. It's in low Earth orbit, so latency isn't really an issue. For Mars, latency is on the order of 15 minutes. For Voyager, it's around 15 hours (one way).
Comment: The large dish antenna on earth is very important for such a large distance like 100 AU. If we use a 3.5 m dish only instead of a 70 m dish, the distance is reduced from 100 AU to only 5 AU. The dish of the space ship is small, about 2 or 3 m diameter, but the transmiiter on earth uses much more power, about 20 kW instead of 10 W. If 10 W only were used on earth, the distance for uplink to space ship would be reduced from 100 to only 2.2 AU.


Question with several subquestions

Question: Suppose one question posting contains several question. If I can answer one question, but cannot answer all of the questions, is it ok to post my answer as an answer, and not just as a comment?
Answer: Yes, partial answers, given as actual answers, are acceptable and even desirable.
If OP of a question in some case should feel they prefer the remaining question as an unanswered question, they could in turn ask a new question, focusing on what is still open and what they have learned from the partial answer.
Of course, both should be done using common sense. For example, the partial answer should be still substantive, and a reasking of the remaining question should be done only (if at all) with some significant delay and clear indication of the earlier question.
Comment: Instead of reasking the remaining question in case of a partial answer, one can also edit the original question and state which parts have been answered by the answers already given, and which parts are still open.
Comment: Good point. Editing is in general preferable. However, there are precedences of questioners (or other interested parties) expressing some discontent that some question is no more in the "unanswered" list while clearly not having been answered. My remark is meant to address these (rare) cases where in earlier discussion the practice I propose was recommended or at least declared admissible, IIRC.

Question with several subquestions


What are the different repetition ranges and for what use?

Question: I read many times here about repetition ranges but I never understood their idea. Why are there different ranges? What are they? And for what purpose should one do?
Also how much weight should one lift for each range?
Comment: possible duplicate of [What are the trade-offs of weight versus repetition?](http://fitness.stackexchange.com/questions/8238/what-are-the-trade-offs-of-weight-versus-repetition)
Answer: People implement different rep ranges because they have different goals. An Olympic lifter who is only concerned with lifting the largest amount of weight possible would train in very low rep ranges (eg. multiple sets of 1-3 reps). Due to the low number of reps completed in each set, heavier weights can be used. This form of training is highly intensive on the Central Nervous System, and you are essentially training it to fire more efficiently. If your goal is to become faster/stronger/more explosive, heavier weight with lower rep range is the range for you. While gaining size is not the primary focus of this rep range it may occur incidentally, though not as dramatically as would happen with a higher rep range.
For muscular hypertrophy (growing the size of your muscles) more volume is required, and rep ranges of 8-10 reps are best for this goal. It might help to focus on really contracting your muscles with each rep, feeling the squeeze in the muscle group you are training. This rep range will also build strength, though not as rapidly as a lower rep range would.
An endurance athlete may perform 12-30+ reps of a certain exercise. Training in this range raises cortisol levels, and this can actually result in the loss of muscle mass. Less mass on your frame means less mass you have to move, which can be beneficial for long distance runners/triathletes/crossfitters.
If your goal is a mix of the above, by all means mix up the rep ranges implemented in your workout. It is not uncommon for people to perform low rep strength sets (e.g 5x5) followed by sets in the hypertrophy range as they are looking to gain strength and size simultaneously.
You should use a weight heavy enough so on the last few reps of your later sets your spotter has to help you. Don't sacrifice good form for reps.
Good luck with your training!
Answer: cant yet comment but if you train for strength purposes you shouldn't train until failure, this zaps your CNS and that will take about 5x times longer than your musculature to bounce back.
basically 1-3 is for strength and produces more muscle activation
4-7 is combined strength and muscle building
8-12 is for building muscle (I believe making more muscle fibers)
and above 12 is for endurance purposes.
The amount of reps usually also matches the weight, so lower reps higher weight en vice versa
Answer: Hi basically anything below 8 is meant to train strength, anywhere between 8-12 reps trains gaining size/mass, and anything 12 and above trains endurance.
And how much weight should you lift for each? to the point were the 9th rep is basically impossible to finish...always train to failure


Is it generally acceptable to answer a question that has an accepted answer?

Question: Some questions continue to percolate even though they have an accepted answer. Is it generally O.K. to enter an on topic response afterwards?
Comment: Thanks. I'm enjoying the site. Nice job.
Comment: Usually I don't accept answers until I feel the topic is closed. But things tend to change over time and a better/more precise or more up to date answer can hopefully emerge. So yes it is OK to answer questions with accepted answers.
Answer: Yes!
Assuming, of course, that you've something useful to add. "Accepted" just means the person who asked the question found the answer helpful - it doesn't mean that answer is necessarily the last word on the topic. If you think you can provide a better answer, or even just answer from a different perspective, then by all means - post it!
Comment: I think this differs from my perspective.  Seeing a "check" next to the answer is usually an indicator that the asker has said "okay, thanks for answering me, I'm good!"  Otherwise, by definition, there is always a "best" answer from the list (that is, a question with just one answer has that as the best question) and the tag becomes meaningless (IMHO)
Comment: Sure - but just because one user (albeit the one who asked the question) is satisfied with it doesn't mean every future reader will be. The whole point of SE is that questions tend to be had by multiple people - a future reader with the same problem may well find your answer more useful. That doesn't mean every question needs loads of answers... But if you see an opportunity to expand on the knowledge provided, you're more than welcome to do so.
Answer: If you can edit your information into an existing answer (i.e. it's supplementary rather than contradictory) that's better than a new answer.
Otherwise, new answers to already-answered questions are a normal part of SE - though in my experience on other sites, they are usually not great quality (most often restatements of an existing answer, and usually not as insightful) so I find I tend to downvote them anyway.
Answer: As Shog9 and Joe state (and demonstrate): Yes, there's nothing wrong with adding a useful answer to a question that already has an accepted answer - indeed I remember there being a discussion about how we could tactfully suggest that new users don't accept answers straight away on SO, because seeing that a question already had an accepted answer was perceived as discouraging others from answering.
It's also useful when technology or techniques have moved on - especially on programming sites where questions might be about Beta software, but even here, if the LEGO Group were to release a new brick that makes a particular form of SNOT building easier, then by all means post more answers about it.
Generally though, usually it's just people saying "Thanks that helped me too" because they can post an answer with no rep, but can't add a comment.


Why are there two Enter keys and two ALT keys etc… on a general windows PC's keyboard?

Question: I am not a typing expert but I found it unusual to have some keys been repeated on keyboard. What's the logic behind this?
Comment: @kinokijuf This does not hold true for all keyboards. Many US, Brazilian, Dutch, and Korean keyboards do not have an AltGr. UK, Latvian, Polish, Belgian, German, Hebrew, French... do.
Comment: Well the second enter, at least on a US keyboard, is specifically for the numpad so you can use it one handed
Comment: There is only one Alt key. The right one is AltGr, used for international characters.
Comment: Please tell me the reason of your downvote whoever did this so that I could improve my question.
Answer: I believe it's merely for the ergonomic benefit. Especially when touch typing.
Imagine if you want to type "A" and you would have to use the right shift key. Try it for yourself. I would need my both hands, because I can't reach it.
You can find more information on wiki: http://en.wikipedia.org/wiki/Touch_typing
And also in a related post over at SuperUser:
https://superuser.com/questions/304295/why-are-there-two-sets-of-the-ctrl-alt-and-shift-modifier-keys-on-the-keyboard
Keep in mind that some of the "duplicate" keys (may) have other functions.
Answer: As a matter of fact, there aren't two Enter keys on a keyboard - one of them is 'Enter' and the other one 'Return'.
With some old machines (and even sometimes nowadays in applications) these keys had a different function. From Wikipedia:

For example, while using the type tool in Adobe Photoshop, the return key produces a new line while the enter key ends editing mode.
On IBM's 3270 and 5250 line of terminals, the Enter key was located to the right of the space bar and was used to send the contents of the terminal's buffer to the host computer. The Return key was located in a more standard location and was used to generate a new line.
Apple also took advantage of this situation to create a highly editable command line environment called a "Worksheet" in the Macintosh Programmer's Workshop, where return was used strictly as a formatting key while enter was used to execute a shell command or series of commands in direct mode.
In technical terms, the Macintosh keyboard maps the return key to a carriage return, while the enter key maps to a newline.
Answer: As someone who learnt to touch type only some of the duplicate keys are useful to a touch typist (such as Shift which existed on typewriter keyboards).
The history of keyboard design is really the history of the IBM Keyboard - which started out as a mainframe keyboard and had to cope with legacy functions from other input devices.-
Answer: All keys that need to be used in combination are duplicated on the keyboard. So that you can use both your hands easily for all the keys on the keyboard. For example, Alt A, will be used by pressing Alt with your right hand, and A with your left hand. Same logic for Alt L.
Answer: The duplicate keys can usually be re-mapped to other useful shortcuts (like copy and paste instead of having to hit multiple keys to perform these shortcuts) or program specific controls to make certain functions easier (e.g. in gaming, you may map these buttons so they perform in-game commands). It's helpful to have a few extra buttons available on the keyboard for this so that you're not overwriting keys that may be necessary, but they have default values so that they're still useful when not otherwise set to custom functions.
Comment: This is the case, but it's only a way in which having two is incidentally useful for some people - it's not the original reason why we have two. There were two shift keys on keyboards well before the concept of remapping: see [mechanical typewriters](http://upload.wikimedia.org/wikipedia/commons/3/33/Old_typewriter.jpg) (the umschalt key is the shift key) and [electronic typewriters](http://upload.wikimedia.org/wikipedia/commons/9/91/Selectric_II.jpg).
Comment: But this is not the case for having two (or even one!) set of Ctrl, Alt, Cmd, etc. I agree that Shift has been around since early typing (in fact, this is why I upvoted the answer explaining why you might need two Shift keys), but the other keys didn't exist until computer keyboards).


How do you say "creepy"?

Question: If you really think about it, some magical guy entering your house through the chimney in the middle of the night is kind of creepy. But how do you say creepy in Esperanto?
Answer: I think timetiga is fine. Dictionaries give things like tremiga and harstariga. Here are some ideas:

koboldeca, diableca, fantomeca — goblinish, devilish, ghostly
harstariga, (tim)tremiga — hair-raising, shiver-inducing
maltrankviliga — causing unease
perturbanta — disturbing (usually literally)
misa — wrong, out-of-kilter
antaŭsentiga — causing a feeling in advance (usually apprehension)
mava; maveska, mavŝajna — evil; with the trappings of evil
ŝteleca, ŝteleska — stealthy
minaca, misaŭgura — threatening, ill-omened
Comment: I like a lot of those suggestions :-). But some of them seem more spooky than creepy (tricky distinction, I know)...

What is the genre of "Cocaine" by Eric Clapton?

Question: I am very much in love with the music Cocaine by Eric Clapton. What is the genre of this song? If possible suggest me some more songs like this.
Answer: I'd qualify that by labeling this as blues-rock. "Cocaine" is a modified 12-bar blues. If you search for blues albums from the 1970s and 1980s, you'll find plenty there. Try Stevie Ray Vaughan, Robert Cray, Buddy Guy, and even the late B.B. King. Guys who sound like Clapton would be more those who came up in the UK in the 1960s, like Rory Gallagher and Jeff Beck.
Comment: Thanks for input. It was very much helpful and I will start listening to everyone of them.
Answer: The genre is called "rock music". The song was written by J. J. Cale. Look for more recordings of songs that he wrote, and look for more rock songs from the late 1970s. Look for more songs recorded by Eric Clapton from the late 1970s.
Comment: Rock is too large a genre to be helpful to the OP, IMHO.
Comment: @ChrisSunami I agree, way too much blues influence to only be classified as "rock music".  Although classic rock radio will often group it with other "rock music" (as well as more traditional blues-rock).


Good book/reference for AVR coding in pure C/C++?

Question: Can someone recommend a good book/reference for going vanilla (i.e. not using arduino simplified language) on e.g. ATtiny85? I will need to use the equivalents of analogRead() and digitalRead() quite a bit. And is softwareserial the best method for debug output? I have less than 8KB of flash, so any advice on that (and reduction of binary for upload) would also be greatly appreciated.
Comment: Have you tried Atmel's datasheets and application notes?
Comment: Yes, I am looking for something to supplement those. A collection of commented programs for ATtiny85 would be good, or a beginner/medium book/reference. The avrfreaks forum is very good, but I need more.
Answer: First, let's make this clear: The Arduino environment does not provide a
"simplified language": it provides a simple hardware abstraction layer
through its core library. The language is plain C++.
Like Talk2, I don't have good book recommendations. The basics of
low-level programming are covered in the Arduino tutorial on port
manipulation[]. Past this you will have to dig into the datasheet of
your MCU. Look also at the doc of the avr-libc and the tutorials in
Nick Gammon's microprocessors pages.
I would suggest you try to develop your program like this:

Do the initial prototype of your idea on an Arduino Uno (or similar)
using the Arduino libraries. It just makes things easier, and you are
more likely to get a working prototype pretty fast.
Once the initial idea works, optimize it for the limited resources of
the ATtiny85. This may involve replacing some call to the Arduino
libs with avr-libc and/or direct port access.
You may then want to remove all references to Arduino core, but you
don't have to: there are some ATtiny cores available that you can use
if you want.
If it now fits in less than 8 K, port to the ATtiny.

The thing I love about the Arduino environment is that you can very
easily mix and match abstraction levels: you can have, in the same
program, calls to Arduino core, to avr-libc, direct port access, and
even inline assembly if want to. You don't even need to stick to the
setup() and loop() method: you can write your own main() if you
prefer, just remember to call init() to initialize the Arduino core if
you are going to use it. Oh, and you don't have to use the Arduino IDE
either if you don't like it (I don't).
As for the optimization tips, I would recommend :

Use direct port access instead of digitalRead(), because that
function is pretty big and slow.
analogRead() may not be that bad, size wise, but it has a serious
shortcoming: it's a blocking function which spends 104 µs in a
spin loop, just waiting for the ADC result. If your CPU has better
things to do, you may want to implement a non-blocking read instead.
For debugging output, the most efficient option is likely to be the
USI port. You will have to search for a driver or implement your own
based on the Atmel application note AVR307: Half Duplex UART Using
the USI Module. Alternatively, you could use something like
AltSoftSerial. Do not use SoftwareSerial: it blocks interrupts for
insanely long amounts of time.
Use the command avr-nm --size-sort -Crtd my_program.elf to get a
listing of the functions of your program sorted by flash usage. This
will help you choose good targets for size optimization.
Comment: This is as near to perfect as reality permits. Thank you very much :)
Answer: I can recommend the book "Make: AVR Programming", which uses avr-gcc directly. The Arduino IDE is mentioned at one point, but just in order to "place" it, and to explain how to use its libraries in your own code. You can study all the code used in the book right here (github link).
(late answer, I know, I was searching for other books that don't use the Arduino IDE and stumbled upon this question)
Answer: If you abandon the Arduino paradigm you will be pushed into dealing with setting up all the hardware that makes today's embedded processor so flexible.  This usually takes an experienced embedded programmer days if not weeks to get through on a new processor.  You will also need a dedicated Atmel programmer as you will no longer be using the Arduino boot loader.
Once you get past these obstacles, you can start studying C and C++. The "grand dad" C reference book would be by the "first guys" that did C, Kernighan & Ritchie.  The equivalent C++ book (if you are up to it) would be by Bjarne Stroustrup.
However...
What have you gained by abandoning the Arduino paradigm?
Some would say, not much.
Most of why programming in the Arduino paradigm is easy has to do with Arduino libraries.  They "abstract" the hardware down to a couple simple function calls.  For example, with one function call you can set up the pulse train that can position a servo motor using a familiar term: degrees.
It should also be pointed out that the compiler Arduino uses is a C / C++ compiler.  And that most Arduino libraries are purposely written in C++.
Perhaps writing a C++ Arduino library is a good way to learn C++.  Start by finding the code to libraries that you already use.  Then reviewing how the C++ code is put together.  Finally write you own C++ Arduino library.
Answer: Sorry, I don't have any book recommendation apart from the AVR Datasheet.
You could try to use AVR-LIBC as a abstraction layer instead of playing directly with individual registers: http://www.nongnu.org/avr-libc/.
That might help you saving some Ks on your code which the Arduino layer might be adding. Just make sure you have a proper IDE to assist you with code-completion and navigation.
Also Atmel has a good link how to optimize your C code: http://www.atmel.com/images/doc8453.pdf, which I had a look when doing some bootloader coding.
Finally, you could explore the Arduino libraries, and see the overhead added to each function, like "analogRead()" from your example. Most of the Arduino funcions will be a layer on top of the AVR-GCC, so it'll be a good learning exercise - again, get a proper IDE that helps with auto-completion and navigation.
Cheers
Comment: avr-libc does very little to abstract the hardware: you are still going to access the hardware registers "manually". Only it is easier with avr-libc, as it lets you write things like `PORTB |= _BV(2);` instead of `* (volatile uint8_t *) 0x25 = 1 << 2;`. The generated code is the same (namely `sbi 0x5, 2`).
Answer: The Arduino implements a subset of c++. I am not sure what you expect to achieve by not using it.
If you are really after optimum code, there is no obligation to use any inbuilt function and you can code your own.
Most conventional compilers use a standard runtime library. The reason Arduino does not is because of the limited memory. It is necessary to omit many standard functions to save space.
By not using a library only functionality you need is actually linked in.
Comment: The Arduino core **is** a runtime library, built on top of avr-libc, which is itself another runtime library. But the linker is smart enough to only link into your program the functions you do use.
Comment: @EdgarBonet if it only links used functions it is a library which produces a staticly-linked executable, but not a "runtime library" which is loaded in its entirety by the OS - non-existent on the Arduino.
Comment: Yes, these are statically linked libraries. If by "runtime library" you mean a library loaded in its entirety by the OS (I would call that a "dynamic library"), then no, there is not, simply because there is no OS. There is a "C runtime" though, courtesy of avr-libc (the files crt*.o): it contains the interrupt vector table, the catchall interrupt, the initializations of r1, SREG and the stack, and the calls to `main()` and `exit()`.


How to handle business users and an application that requires GPS access

Question: We currently manage an application that is sold exclusively to businesses, but users can use the application on any device.  Our app requires location services to be on to function properly but does not require location services to run all functionality.  The location of the users is proving to be business critical information though and we are receiving more requests to force users to turn on location before using any of the app.  How best do we encourage users/ force malicious users to turn on location services on the device and not turn it off?
Answer: You shouldn't ever force your users to do something. As soon as you start doing that, you will begin to quickly lose users. Users need to be given an incentive to turn it on and keep it on. If your users don't feel like they are getting a good enough deal from what your application has to offer, they will not keep it on.
The best approach would be to softly remind users with Android's built in notifications that their location that they are not receiving the full functionality. So once every couple days or so, the user would get something like the image below on their lock screen. That way, the user will know that they are not using the app to it's highest potential.

image source
Answer: It seems to me that you have a value delivery problem for business and returning this into benefit to users. If you need the feature of geolocation has to be mandatory, show them very clear in the beginning of the use with a walkthrough or small hints.
Some apps asking to turn on resources like gps, before the user start to explore the interface (moovit) and others only when you will share some information with the community or a friend through the app (facebook).


Using third-party recruiter as middle man for communications?

Question: I'm scheduled to go in for an interview at Company X (a software development startup). I found out about the position through a third-party recruiting agency, specifically from a recruiter who I'll call Bob.
Bob mentioned to me in passing that this is their first time working with Company X. I don't know if Company X has worked with other recruiting agencies in the past.
The HR rep from the company has been emailing me directly, but Bob clearly thinks that he's meant to be the go-between for all communications.
When we were scheduling the interview, Bob texted me asking if a specific time would work. I had already told him (and the HR rep, during my phone interview) that I could do the morning on that specific day, but I hadn't been explicit about what time I'd need to leave.
Right after seeing Bob's text, I saw an email from the HR rep confirming that I was scheduled for X time (the time that Bob had said), and giving me the interview schedule.
I contacted Bob telling him that the time was fine, but I'd need to leave by noon, and I mentioned that the HR fellow had already sent me the schedule. Bob seemed a bit surprised by that, so I forwarded him the schedule so he could see it. The problem was, the schedule showed that the interviews would end at 1pm instead of noon... and I really couldn't rearrange my meetings that specific afternoon.
I wasn't sure what to do, so I let Bob call up the company to reschedule. I didn't reply to the HR's email. Bob managed to move the interview up by an hour so it works with my schedule now.
Thankfully that worked out fine, but I haven't gotten an updated schedule from the HR rep yet. If I don't get that within a few more days, I plan to follow up - but I don't know if I should follow up with the recruiter or directly with the HR rep.
It's worth noting that this duplication/misalignment on the communication has happened a few other times too (in more minor ways, ie. when scheduling the phone screen and when receiving a pre-screen assessment, the HR and recruiter didn't seem to be totally aligned on who should be communicating with me.) Likewise, after the phone interview, Bob asked me to send my thank you note directly to him, and he'd forward it along to the HR interviewer. (I followed those instructions).
I've talked with recruiters before, but this is my first time progressing to the interview stage with a job that came through a recruiter... And this all seems a bit weird to me; however, I'm still fairly new to the marketplace (I'm junior developer going through the job-switching process for the first time).
Is it normal that companies and recruiting agencies might not be totally synced on who does the communication?
Do I need to be concerned that this will reflect badly on me? (ie. that the HR rep will wonder why I'm not responding directly to her emails)?
When I receive messages directly from the HR rep, who should I reply to? Keep Bob in the loop and ask him to forward my reply, or just reply directly to the HR rep?
If this job goes through, Bob will obviously get a commission (and judging by his behavior and help, he's expecting a large one :) ). However, is there a point in the process when he should fade out of the picture until the company makes their final hiring decision?
Answer: I got my current job over a year ago through a recruiter. He was very helpful, professional and he didn't act like a middle man between my and the company at all. As soon as I told him that I'm interested and company confirmed they want to interview me, he send them my phone number and he only contacted me only after I signed my contract.
I have no idea why he acts like a middle man, it's extra work for him so maybe he wants to show his effort to the company (as they're Bob's customer). But I do think it's definitely strange.


Let the young ones speak first?

Question: I remember reading that, in the Sanhedrin, the most junior rabbis were encouraged to speak first, so that they would not be swayed or intimidated by the more senior ones.  Is this true and what is the source?
Comment: @ezra, i think such a custom of having the younger speak first is specific to the Sanhedrin which requires a fair vote. If some judges are unduly influenced then the vote is not fair. However, there is no such need for absolute fairness in a family or friend discussion, hence we respect the elders first. Job is not a contradiction to Sanhedrin.
Comment: "Now Elihu waited [to reply] to Job with words because they were older than he in days." ([Job 32:4](https://www.chabad.org/library/bible_cdo/aid/16434/jewish/Chapter-32.htm#v=4)) Apparently what you are saying wasn't true in Job's time.
Answer: This is the rule for capital cases so as to be extra sure every possible leniency is considered before executing someone. See Mishna Sanhedrin 4:2 with commentaries.
Comment: @Maurice not necessarily so. It depends if the senior members demand the respect they are owed. They could choose to waive their right to speak first. IINM R Yehuda HaNasi was known for doing so.
Comment: @Benyomin hmm try the Tosfot Yom Tov to that Mishna. Or maybe Bartenura?
Comment: But in monetary cases, the most prestigious rules first. (Just clarifying the implication.)
Comment: So, let me summarize.  "The young speak first" is ONLY in Sanhedrin trials where the defendant may get the death penalty.  In all other cases, especially for halachic rulings, that is not so.  Correct?  "Not so" or "Not necessarily so" (i.e., are the young even ALLOWED to speak first)?
Comment: According to Rambam this is necessarily so. See Mishneh Torah, Sanhedrin, ch. 11, law 6. "With regard to cases involving monetary matters and similarly questions of ritual purity and impurity, the judge of the greatest stature gives his ruling first and the other judges hear his ruling. With regard to laws involving capital punishment, we begin from the side. The words of the judge of the highest stature are not heard until the end."
Comment: @DoubleAA Very interesting! Do you know off the top of your head where I can find this?
Comment: @DoubleAA Yes, I see. Tosfot Yom Tov explains that based on Rashi. Thanks!

Are answers being posted as comments?

Question: I'm not sure if it's just me, but I've been seeing a lot of answers that are being posted in comments. Nothing wrong with that, per se, but I would like to be able to upvote that as an answer that gives the commenter more rep.
Example
Answer: Encouraging them to post it as an answer is an excellent way to remedy this.
Then there is Jeff's definitive answer:
Comment: or, stealing it and posting it as an answer yourself (assuming the Q is valid) -- this is allowed and even encouraged, but do mention the comment owner in your answer. *.. AND THEN RAKE IN THOSE SWEET HOT VOTES!!*
Comment: way to steal the comment :)
Comment: 8 pixels less and you wouldn't have that funky anti-aliasing on the comment screenshot
Comment: @Renesis: I tried to trim it, let me go at it again.
Answer:
I usually put an answer as a comment when the question is likely to be closed (or when I vote to close) but want to help the OP anyway.
I also put an answer as a comment when I feel my answer does not deserve the exposure of an answer but may help the OP anyway.
Finally, I use comment to put some humor sometimes that definitely doesn't deserve to be made as an answer.
Comment: Perfect list - For me there is a sub-part of #2, where the answer is only a part answer or side-note (but may help the OP anyway)
Answer: Comments as answers are becoming more common on some sites. This is a problem because once a comment-based answer is posted, most users will not feel compelled to provide a proper answer. The question then remains squarely in the 'unanswered' column. Besides, comments-as-answers cannot be vetted, and voted on properly so the best answers don't always appear on the top.
The comment authors should be asked to post their comment as an answer. Failing that, comment-based answers are fair game. Post the answer yourself and flag the errant comment for removal.
Answer: I frequently use comments as answers if I think that the question doesn't meet our guidelines, but I feel like responding anyway. However, I usually mention that I don't think it meets the guidelines in my comment.
Comment: +1 for being what I was going to write.
Answer: As I see it the answers in comments are usually poor quality and not of significant value. They detract from using comments to get to the real question.
I have also see controversial answers posted in comments, possibly as you cannot be down voted and loose points for a comment.  I feel that they should be discouraged, and ideally comment able to be up/down voted and points allocated.

How does sequence independent single primer amplification work?

Question: I'm having difficulty finding an explanation of how single primer amplification of DNA works in the literature available to me, can anyone explain the methodology and what it accomplishes?
Answer: This process is called sequence-independent single primer amplification (or in short SISPA). Its used to amplify unknown sequences for amplification, for example in unknown viruses.
The primers used for this process contain random sequences which should bind to the DNA to be amplified and also known sequences, which can be used a adapters. In the first rounds of PCR only the random primers give rise to specific products, which are amplified exponentially in the later rounds of PCR since the primers fit perfectly then. This is described in detail in this publication:"Random priming PCR strategy to amplify and clone trace amounts of DNA"
Another interesting paper describing the method is:"Sequence-independent, single-primer amplification (SISPA) of complex DNA populations."
Answer: single primer amplification is used to find unknown regions of DNA if you have no idea what to use as a primer further upstream. It works on the idea that any primer given a certain temperature will misprime. That it, it will anneal to a non specific location. So it is PCR, but at this temperature, the five prime region primer will bind specifically to it's known location. On the three prime end up to 3500 bases away, the low annealing temperature will allow this specific primer to bind to something resembling its complementary sequence but not exactly. This way you will still get a successful PCR reaction. Then as the cycles continue, the 3' end binds specifically to your one primer and you can raise the temperature to make it more specific. The primer design and temperatures have to be considered very carefully.

Can't find ATI Mobility Radeon HD 6370 driver for Ubuntu 12.10 64-bit on HP Pavilion DV7-4285dx

Question: I've got an HP Pavilion DV7-4285dx that has switchable graphics between some generic Intel card and the discrete card, an ATI Mobility Radeon HD 6370. I'd like to be able to use that ATI card for high performance graphics on my laptop in Ubuntu but when I try to use the fglrx drivers, it still says that only the Intel card is being used. I installed AMD's ATI Radeon HD 63xx series drivers but that led to Ubuntu booting and going attempting to go into "Low graphics mode" which ended up just freezing on the "low graphics mode" selection screen, so I went into ctrl+alt+f1 console and reinstalled the fglrx driver so I could reboot into Linux. I assume it didn't work because my card is the ATI Mobility Radeon HD6370 which is apparently not the same as ATI Radeon HD 63xx series.
Now that you know my life story, has anybody been able to get the ATI Mobility Radeon HD 6370 working in Ubuntu 12.10 64-bit, or any other version of Ubuntu for that matter?
Thanks in advance
-Rob
Comment: Maybe they have something for 32-bit?
Answer: Give a try to this how to and it should help you install the driver at the

One hour 10 min layover in Newark; International -> Domestic connection. Enough time to clear customs?

Question: Flight is Barcelona -> Newark -> Rochester NY.
Layover in Newark is 1 hr 10 min. Will I have enough time to go through immigration, collect bags, customs and security in order to make my connection? Also traveling with 5 mos old infant.
Single ticket, travel is on a Thursday.
Both baby and I are US nationals.
Class is Premium Plus Economy
Comment: Very risky, good chance to miss the connection. Is this a single ticket or two separate tickets?
Comment: Very unlikely especially with an infant. You need to clear immigration, wait for bags, exit custom, go to your terminal, go through security again. With Global Entry, no bags and TSA pre-check, this may work, but not with bags and baby.
Comment: The cynical part of me says "no problem, everything our of Newark is delayed by a few hours"
Comment: I suppose we are talking about flights UA121 and UA4895. The former is "Often delayed by 30+ min", which reduces your chances of making the connection even further. The next flight is 6 hours later, which is already quite a long wait, but it gets even worse if that flight is full...
Comment: Never been through Newark, but it would depend on the day of the week and time of day. Any more details you could add to your question would help
Comment: I recently flew CDG-OAK and waited 90 minutes on that (relatively) small airport. I waited 2h30 in ORD once (just because it was a mess that day). Coming back to France I waited less than 5 minutes at the border -- so you never know but I would not take any chances.
Comment: Are you a traditionally clothed Muslim from Iran with relatives on the no-fly list and no return ticket booked? I am sure you are not, but it would be relevant to know your nationality /ies and if you know of any stamps in the passport that will cause problems. Have you been to the US before?
Comment: If the two flights are not on the same ticket/booking, then no, it's completely impossible, even if you didn't have to clear immigration. If the two flights are on the same booking, then that means the airline thinks this is possible, and should rebook you if miss your flight, but that can add long delays, which are not quite something you want to consider with an infant. Also, what date are you travelling, and what is your nationality/visa status?
Comment: I have gone through Newark 3-4 times, and every time it have taken at least 1 hr before I have gotten my luggage after immigration
Comment: Not a chance of making this
Comment: Newark airport is the quickest I've ever been through immigration in the States, a couple of minutes as there was no queue, still tight though.
Answer: Even without immigration and an infant it would be very tight on most airports.
The time immigration takes does depend on the time of day and day of the week but also on your relative location in the queue/line and with a baby everything takes more time.
I have been in an USA immigration queue for more than an hour with it being just one plane, different airport.
Customs can take no more time than you need to walk through one short corridor or it can take quite a while if they want to check your luggage and there are already people waiting. An hour wait is realistic.
If your ticket is for both flights you can risk it, knowing that the airline will get you to your destination at the first possible option. Also because many flights do land early.
But if you have important things to do shortly after arrival or an ongoing connection not covered by the same ticket or travel on separate tickets I would not even risk it with three hours.
You have added that you and the baby are both US citizens and the class of the single ticket. That is good, as you will have the easier line through immigration, (which you may be able to improve on if you can get one of the faster methods to get through the checks like Global Entry TSA pre-check,) but you will still have quite a distance to walk and a baby to take care of. A sling or carry frame for your child may make it easier, as it is rather likely you will not be able to use a pram, (due to it not traveling in the cabin with you.)
So I see your chances as slightly better than the average passenger on your flight, but it can still be a tight fit if the flight is on time and impossible if your incoming flight is late.
So it is still rather likely that you miss the plane and will have to wait in the airport for the next one with space. You may like it better to book the later ongoing flight (so you know you have a few hours in the airport and be sure you get on the next flight) and maybe invest in a hotel room (so your little one and you can get rest in private) or in buying entry for a lounge. (I have never done that but I often read here that it is possible and worth it.)
Comment: Good answer. I would add that cabin class, airline status, Clear, Global Entry and/or TSA pre-check can considerably speed up things. So it depends A LOT on the detail. I once made a HKG->BOS connection in Newark with less than 30 minutes.
Comment: With a baby, I don't think I'd rely on the airline putting you on the next available flight. I mean, sure, they _will_ put you on the next available flight, but that might not be for hours and hours. That's OK if you're on your own but it's going to be pretty poor with a baby.
Comment: @Hilmar you are bold. I would never book that. I count on 10% delay, and I ride Amtrak a lot, so that can be 5 hours on a transcon. My worst Amtrak delay was 6 hours IAD-SFO, we didn't lose any time once enroute, but we spent 6 hours *before departure* on a  weather hold (erm?) on the tarmac at IAD - oh wait, that wasn't Amtrak at all.  That was JetBlue.
Comment: @Harper: that wasn't by choice: a snow storm cancelled all other EWR BOS flights that day (and pershaps the next too) so I had the choice between running fast or getting stuck in EWR. So running it was. I've certainly seen Amtrak snow delays of 24+ hours in Boston too.
Answer: That's really quite tight and not something I'd be comfortable with, especially with checked bags and an infant (I might give it a shot with Global Entry, no checked bags, and no infant, but that's not your situation here).
The minimum connection time is about 70 minutes, so you're right around the minimum the airline will even let you book. Keep in mind that you need to be at the gate at least 15 minutes before departure time, further reducing your time. There may be enough padding on your flight from Barcelona that you can gain a little time if it arrives early, but there's no guarantee of that.
Connections like these at Newark often require that you change terminals after immigration and customs (it's possible that both flights will use Terminal C), which means going up some escalators, riding the AirTrain, going down some escalators, and then through security. That will take up even more of your time. (I've also experienced atrociously slow baggage service at United's international arrivals at Newark, though it's been about 18 months.)
You can use the CBP AWT site to see past wait times at immigration for the same time and day of the week, which may help you make an informed decision.
I'm not going to say it's impossible if all goes well, but I think there's a decent risk of missing this connection, and any one thing going wrong (delayed arrival into Newark, long lines at immigration, long lines at security, etc...) would be enough to miss it. I'd look at what your options are if this is the case. If you've booked this as a single ticket, United will rebook you on the next available flight with space, but if that flight isn't until tomorrow (or the flights are full), you could be in for a long wait, with your infant, without your checked bags.
If you do decide to try it, and you're a US or Canadian Citizen, I'd get the Mobile Passport Control app, which could help you get through immigration more quickly.
Answer: Based on my experience (including missing a flight, and getting stuck in an airport for an extra night without a visa to go out) anything less than 2 hours, that includes customs and border control involves risk of missing a connection and going through rebooking of the flights. There are many reasons why it may happen, that include suddenly longer lines, random custom inspections, passport checks, and many other ones. Unless you target for establishing a world record for getting the least layover time for a flight ever, you may consider to plan for calm, more relaxed route, to have time to grab something at the airport or visit a restroom without a need to sprinting it.
As a bonus point, you may find maps of airports and really plan your route, including transferring between terminals and international/domestic zones. I believe that this is the one for Newark, and it may give you a better view on the transitions https://www.newarkairport.com/at-airport/airport-maps
Answer: Oh heck no.
The problem is, you have so many steps there, and a complication.  It might have a chance if you were OJ Simpson (once most famous for moving through airports very quickly), but with checked bags and a baby on board, this is risky.  You would have to a) do everything fast, b) do everything just right, and c) have everything out of your control go just right - no late plane, long immigration lines, slow baggage pickup, or extended scrutiny at Immigration.
The stress amplifies all sorts of problems: the rush increases chance of injury.  It greatly increases the chance of mistake, because you're flustered, and don't have time to double-check and ask.  And it stresses you out in the Immigration and Customs line, which can make that go wrong.
If you booked independent tickets, cancel the Rochester segment and rebook something realistic.
If these are all on one ticket, the airline is responsible for the connection.  Move consciously with no wasted time, but refuse to rush.  If the airline sends someone to whisk you through Immigration, baggage collection, Customs and TSA, as well they ought... then take full advantage of it, of course.
Figure on a singificantly delayed arrival in Rochester, and set your hosts' expectations accordingly.
Comment: On independent tickets with hold luggage this is not even remotely possible. The check-in deadline is 45 minutes before departure. This would leave 25 minutes to deplane, get to passport control, go through immigration, reclaim bags, go through customs, get to the check-in area (not familiar with EWR, but most likely a different floor, possibly a different terminal), queue, and drop bags. And that's if the incoming plane is on time. Better chance of winning the lottery...
Comment: @jcaron Agreed, the only way this could possibly work is if airport staff escorted you and velvet-roped you to the front of every line, had a staffer intercepting your luggage, etc. Maybe they have a way to gateway you from the int'l arrivals sterile area to the domestic sterile area...   Or what I would do, pad the daylights out of arrival times for every international flight ... Amtrak does this, that's how any of their trains are on time.  It's like Arlington VA 9:00, WAShington 10:55 *say what?*
Comment: I traveled through Newark two weeks ago (Stockholm via SAS to IAD via United). We had a 2 hour connection, and if we didn't have Global Express, we never would have made the flight: regular lines at immigration were crazy long, and worse for customs. As it was, we had to hustle to get to the other terminal and back through security, and we didn't have an infant in tow.
Answer: Even for me this would be tight and I have a NEXUS card, often flying business and a ton of experience moving through airports and not a baby in sight. The reason I am writing this up because people do not emphasize the baby enough. She/he will be very fussy after landing, the landing hurts their little ears. Hat tip: yawn at that them, they will copy and hopefully pop their ears. Nonetheless you are landing at around 8pm Barcelona time and haul them through a smorgasboard of noise, colors and smells at a time when they would be dead asleep at home. Unless you have a saint, they won't welcome that at all. There are nursing suites (type nursing suites and click search) at Newark, most definitely schedule some quiet time even if you don't nurse them there and then. Yes, you can rush through the airport trying to make this connection but a) you won't make it b) even if you do, the next flight will be unpleasant. Or not. Baby might just decide to fall asleep and stay asleep. I mean, babies :) but that's not an outcome I would expect.


What is the difference between "nofollow" and "noreferrer" link from SEO perspective?

Question: I want to know the main difference between "nofollow" and "noreferrer" link from SEO perspective.
Answer: The difference is that, in theory, rel="noreferrer" should not have any SEO impact, while nofollow clearly specifies that the link does not endorse in any way the target URL.
nofollow was invented by Google back in 2005 in order to fight comment spam in blogs, any URL appearing in the comment section would not pass PR to the target webpage.
rel="noreferrer" mainly affects analytics, how did this visit landed to this page? where comes it from? noreferrer specifies to hide that kind of information.
I said in theory because there is currently no official documentation that explicitly indicates using noreferrer would change anything in SEO terms, but it shouldn't.
Answer: "nofollow" is used by Google, to specify that the Google search spider should not follow that link
"Noreferrer":
Specifies that the browser should not send a HTTP referrer header if the user follows the hyperlink
Comment: I believe that is correct, however it doesn't completely answer the question.   How do each of those effect SEO?
Comment: @StephenOstermiller ~ don't believe that referrer has any impact on SEO, since the usage is intended mainly for privacy and security... I mean why would it? its the same as SSL doesn't refer but none the less Google still rewards external links from and to SSL enabled sites.
Answer: rel="noreferrer" does not affect anything special. It is effected on the
 browser side.But in the case of rel="nofollow". The google bot does not check that link.
This is the main difference between this two options.
Comment: "not affect anything special" -- How is not sending a referrer on click nothing special?
Comment: Absolutely what Stephen said. Not receiving referrer information is a major problem for those doing SEO.
Comment: No referer doesn't send the referring URL to the page in the link. It might be very useful when linking from a private page. Let's say you link to site X from example.com/my-secret-url/ you might consider adding no referer to your link. However, this is done browser side and some browsers might ignore that directive, while major browsers comply.


Wheel locks and spinout

Question: Imagine driving in a straight line on a ice lake, when you hit the brakes, if your goal is to stay in straight path with no spinout, which wheels would you choose to have locked: front or rear? Assuming the steering wheel is kept fixed in both cases, I learned that it's better to have front wheels locked in this case. But can someone explain in accurate terms why? Thanks.
Answer: As in Gugg's answer: Let's consider the car that has slightly rotated, and let's see if the forces that the road applies on each wheel will correct it, or make it worse:

Decompose the friction of the road on the wheel in a parallel and perpendicular component. The momentum of the parallel component of the left and right wheel cancel each other out (assuming symmetrical conditions). So, for the directional stability, only the perpendicular component is important.
The blocking wheels are a regular sliding contact. Here dynamic friction applies.
The braking wheels are still turning, and so the rubber is not(*) moving relative to the road. So in the perpendicular direction static friction applies. The perpendicular component here will be greater than with the sliding wheels. It doesn't even matter if you are braking or not.
So, if the blocking wheels are at the back. A small instability will increase. Whereas, when the blocking wheels are in front, it will be instantly corrected.
(*) Now, you might say: When the car is going sideways, the braking wheels are also sliding, so dynamic friction applies on all four wheels. That's true, but the distinction between static and dynamic friction isn't as black and white as the theory suggests. For a very small rotation, the sliding is minimal and friction is still higher, and that is enough to immediately correct it.
Answer: I think because if you lock rear wheel's and start sliding the car on the ice the front wheel will suffer a frictional force whose line of action could deviate from a straight line parallel to the central line of the car to any other direction causing a resultant force in either direction's which could spin the car. On the other hand if you lock the front wheel the car will start sliding and the rear wheel will suffer a frictional force but in this case the force will align the car in a straight line as  it will be a pull force and will keep the carr straight and prevent it from a spinot.
Answer: For the same reason Michelin recommends always putting new tires on the back first Tires 101 you any slipping (non-rolling) to occur on the front if stability is required.
So to brake on ice and not loose control (spin out) make sure the front tires lock up first and the rear keep rolling maintaining traction. It is the same reason people put caster wheels on the front of a grocery cart and not the back.
Comment: Your average drives does not know how to do this. Time and again I watch the news reporting on some car loosing control and hitting trees.
Answer: A wheel has traction in two component directions: both parallel and perpendicular to the direction of the movement of the car. The perpendicular components, by definition, won't do anything different for the direction of the car. But the parallel components will cause locked wheels to decelerate less in the parallel direction than unlocked (but significantly braking) wheels. Therefore, the rear wheels locking will (as soon as the car is/becomes a little bit angled) cause more rotation than the front wheels locking. That's why.
Comment: @Gugg: it depends how hard you are braking. If eg. you don't brake at all, the parallel component will be insignificant. For the same reason why steering actually works.
Comment: I don't think the force on the braking wheels are necessarily opposite to direction of movement.
Comment: @KrisVanBael: Why is that?

Wheel locks and spinout


Market Cap API?

Question: I am using CryptoCompare's API and it gives me volume data, but I am wondering where I can get market cap / circulating supply data. Do any reliable API's provide this?
Comment: Closed this question 3 years too late - already got my answer!
Answer: Checkout coinmarketcap. they've all API you may need for cryptocurrencies
Answer: As Adam answered, the Coinmarketcap.com API has a ton of data that's aggregated from a ton of sources. Also, it's been around for a while and the API is accessible 24/7, so it's definitely one of the more reliable services. I heard they even filter out sources with outlier data, such as price or volume spikes from artificial pumping or commission-free trades, which makes the data that much more reliable (IMO).
The following URL will return JSON with high-level stats for every coin tracked by the API:
https://api.coinmarketcap.com/v1/ticker/
A sample response is as follows:

Some of the properties you may be interested in are as follows:

"market_cap_usd": Market cap in US dollars.
"available_supply": Circulating supply.
"total_supply": Total supply issued/mined.
"max_supply": Total supply the platform/protocol currently allows for.
Comment: Thanks to you and @Adam for the info - I started off using CryptoCompare and just can't find how to get "Market Cap" data for any coins; figured they would provide "circulating supply" so I could calculate it manually, but they don't seem to provide that data.
Comment: Can "Market Cap" be calculated by multiplying "price" x "total supply"? It seems to be correct when using those values from Cryptocompare.. although I thought you had to use "circulating supply"; not "total supply"...
Comment: https://api.coinmarketcap.com/v1/ticker/coin_name_here_(e.g)_bitcoin/
Comment: Market Capitalization = Total Supply * Current Price.
Answer: i am using cryptocompare too, not sure if it still helps but I believe they have a new page now https://min-api.cryptocompare.com/
go to price - > multiple symbols full data, marketcap for each coin is provided there.
Answer: I'd check out the Nomics API.  It's free, has no rate limits, and gives you more historical data (for free) that CoinMarketCap makes available on it's most expensive plan.
Nomics' free (and paid) crypto exchange data API comes with dozens of endpoints, including endpoints that return sparkline, exchange rate, all-time high (ATH), and supply data.  Also included are historic candle/OHLC data for cryptoasset trading pairs on exchanges like Bithumb, Binance, Bittrex, Bitfinex, Bitflyer, Gate.io, Coinbase Pro/GDAX, Gemini, HitBTC, Kraken, and Poloniex.
One notable difference between Nomics' API and competition is that the Nomics product has no rate limits.  For example, CryptoCompare and CoinMarketCap's APIs all limit the number of application programming interface calls that can be made per minute, whereas Nomics does not currently impose such limits.
Disclosure: I'm one of the founders of Nomics.

How long can a pitcher of tap water be left out, and still be drinkable?

Question: My parents say that flies can lay eggs in the water (we do have flies occassionally buzzing around in our apartment). Is this true? If so, what is the longest time that a pitcher of tap water could be left sitting on a table untouched, and still be drinkable?
Comment: Lemme guess: your parents are also fans of water in sealed plastic bottles that leach **[BPA](http://en.wikipedia.org/wiki/Bisphenol_A)** ("If I pay for it, it must be safer...").
Comment: That flies thing sounds a little sketchy to me. The water container isn't open, right?
Comment: The water container is open, and after a whole day or 8 hours, I can see through the glass bubbles forming along the side. I sometimes forget to change the pitcher of water for many days in a row, and I'm not sure if it would still be safe to drink
Comment: I remember in chemistry classes, there was a container that was specifically water that had been left to sit for more than a day ... but I can't remember what it was specifically called, or what we used it for.
Comment: Hi! We do answer food safety questions, but not health questions. The difference is that, with food safety, you have a chance to get into the hospital the next day, the cause clearly traceable to a batch of food you ate. "Health" is defined as anything else, such as "might increase your risk for cancer/Alzheimer/whatever over time". So, I had to edit out your "ions" question, it's off topic. Parasites are OK, as they are part of food safety.
Answer: If you have a clean glass pitcher, the length of time we're talking is months, as mentioned by Tom's answer.
I think you have a few questions that I can clear up:

The bubbles that form over time are dissolved gases. From the faucet (or pitcher), the act of pouring will force some air into the water. Over time, it will warm up and you'll see bubbles form along the glass. This is absolutely harmless.
Flies laying eggs? Well, I wouldn't leave a glass pitcher out and uncovered, but I highly doubt this. Flies want to lay eggs in places where the hatching egg can live. For example, trash, spoiled fruit, the gunk in your drain, etc..
Chemical reactions with dissolved ions? Since most water in the US is fluoridated, there will be some very slow etching of the glass by fluoride ions. The amount of this will be very, very small, since it's a slow process. I think you'll easily be safe over the timescale of days to a week or two.

So what happens to water left at room temperature over a few days? Mainly the dissolved gasses come out. I find this water to taste "flat" even if I cool it again. But there's not much that will happen to the water.
More than a few days and I'd suggest making sure the water is capped or closed to avoid dust or other things falling into the water. Maybe find a closable glass container?
Comment: Flat water can be re-aerated by pouring it back and forth between containers a few times.
Comment: I should comment on some of the discussion including plastic bottles. That's a whole different ball of wax, since some plastics can clearly leach into the water. The OP mentioned a glass pitcher.
Answer: This excerpt speaks in part to your question.

When it comes to storing water for long periods, the answer is "Yes,"
  your H2O can certainly become unsafe to drink, says Zane Satterfield,
  an engineer scientist with the National Environmental Services Center
  at West Virginia University. "Most experts will tell you tap water has
  a shelf-life of six months," Satterfield says. "After that point, the
  chlorine dissipates to the point that bacteria and algae start to
  grow." That growth will speed up if you store your water in a warm or
  sunny spot—or in a glass container that hasn't been thoroughly washed
  or sealed, he adds.

Consumable water by definition is chock full of compounds and molecules other than H20 which, obviously, have the power to sour water over time. This is perhaps just as well, as water at its purest grade is actually toxic. Known as clean water, and more particularly as ultra-pure water (UPW), it is manufactured for use industrially and, if drunk, draws minerals out of the human body like a magnet. See The Big Thirst by Charles Fishman for more details on the subject. Its relevance? If used for cooking or preparing food it would also draw out its minerals (up to some limit).

By and large however a question of this sort comes in as little more than esoteric, perhaps even pointless. Long before the water could develop anything in the way of health risks, (which itself is outside the scope of these discussions), the water would become simply unpalatable. Even many hours unattended can lead to this, in which case one would simply replace it with a fresh round.
Comment: I am assuming this response speaks to water in a CLOSED container.  The fact that the OP is writing about a pitcher that is open to the air, provides an added dimension to the question, which I don't think this response addresses.  Of course, you may not have known that when you posted.
Comment: What is not sealed is open @moscafj, if your speaking to the quote I posted. So I'm not clear about the assumption you've made. More broadly though there's no reason to view each subsequent statement only through the lens of what a quote contains, not in this or any other answer. But thank you for your dedication to the terms of the question, as that's where primacy always should be given.
Comment: I stand corrected, @Tom Raywood.
Answer: Flies can certainly lay eggs in water left to sit around. But they are unlikely to be a concern, as the flies which are human parasites don't tend to be the water-egg-laying kind. If there are larvae in there, you'll just digest them, no harm done.
The problem can come from two directions: amoebae and bacteria. Amoebae can cause a kind of dysentery. And among the bacteria, Legionella can survive in water, and causes illness, including pneumonia.
I don't know how long tap water needs before it becomes dangerous, normally you shouldn't keep it out more than a few days.
Comment: Well, you learn something new every day. I hadn't realized amoebae could spread to tap water, but I looked it up and indeed there are airborne cysts. Thanks!
Comment: and for amoebae we could broaden that to protozoa and even metazoan parasites.
Answer: Please note that in many countries only cold tapped water is guaranteed to be drinkable. The hot one is supposed to be at 75°C but may never reach this temperature or be kept at it way too long. Either way, when it gets mixed with the cold one, the temperature of the mixture is often very suitable for germs. So, in my experience, the cold water can be kept for couple weeks, especially if in glass container and in the fridge. However, I try to avoid drinking water that was warm for more than a day. I also find water in PET bottles to get a nasty by-taste after a week or so.
Comment: That was brought up in [Things You Might Not Know](https://www.youtube.com/watch?v=HfHgUu_8KgA) in which he mentioned that the hot water might come from a storage tank ... which could have less than desired qualities to it.  Also, I was thinking about it, and water sitting in a pitcher for a long time could be classified as 'stagnant water'.


Using VS 2010 to develop for SharePoint 2007

Question: I would like to know how I can use VS 2010 to write custom WebParts for SharePoint 2007? VS 2010 does not give you any project templates for SharePoint 2007. Has anyone used VS 2010 for SharePoint 2007 development?
Answer: The best Visual Studio plugin I ever used for SP2007 development, SPVisualDev, is avaliable for Visual Studio 2010:

Visual Studio 2010 is now supported. Note that this add-in is only
  intended to be used for MOSS 2007 / WSS 3.0 development and not for SP
  2010.

SPVisualDev is a great tool, which natively allows remote debugging on virtual machine, and also it support model of quick, ASP.Net-like deployment of SharePoint mapped files, on-build deployment of assembly to GAC, and also it provides very convenient and flexible interface to deal with features (and all this - remotely, and plus remote debugging).
Highly recommended.
Actually, I wouldn't say that the current native SharePoint Developer Tools from Microsoft, even with great bunch of improvements from CKS:Dev, is better than SPVisualDev. That's pity, but I'm afraid that's truth :(
Answer: We apologize that Visual Studio 2010 Developer tools will only be available for SharePoint 2010
I am not sure if VSeWSS 1.3 to work with VS2010, but you're probably better off using STSDev or WSPBuilder for 2007 development anyway, which could probably be made to work with VS2010 if they don't already.
Answer: hmm.. I guess there is some confusion.. VS2010 does support developing artifacts for SP2007.
Just to avoid the risk of any binary version mis-match, I will recommend VS2008 + VSeWSS3.0
Answer: I found this useful guide:
http://tallday.wordpress.com/2010/12/16/developing-sharepoint-2007-webparts-using-visual-studio-2010/
I have not tried it, but it does save having to install both Visual Studios side by side.


IIS 7 Cannot Access Website

Question: We can access our website from other systems, but when logged into the local machine where the site is hosted it does not resolve to the site... for example: http://mysite.com/folder/page.aspx   gets a 404.... from the local machine we also cannot ping mysite.com ... What are some common things to check to troubleshoot this issue? I'm new to IIS 7 so sorry for the vague question.
Answer: Sounds like a DNS issue. Setup an additional binding to port 80 with a blank host name. Then access the site via http://localhost/ or http://127.0.0.1 - you should then see it. Then it's a case of diagnosing the DNS issue.
One solution would be to 'hardcode' it in the hosts file (C:\Windows\System32\Drivers\Etc\hosts) as 127.0.0.1 mysite.com
Answer: In 2003 R2 and up, there is a security thing preventing you from using a alias to reach the localhost.
You can either add an OptionalName using this command (fill in ALIAS):
<code>netdom computername ALIAS /add
</code>
Or just turn off the security check altogether (if you run the first command, it will create a OptionalName key in this same location):

Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
On the Edit menu, click Add Value, and then add the following registry value:
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1
Answer: Reviewing the W3SVC logs is a common thing to check to troubleshoot this issue.
See here for more info on IIS logging:
http://learn.iis.net/page.aspx/579/advanced-logging-for-iis-70---custom-logging/
Specifically in your case, confirming the substatus code for the 404 may prove useful.  Use this article to decipher these codes in IIS7:
