A letter to my teeth. I am sorry for neglecting you for so many years. Even after I have become aware of how destructive it can be, I continue to wear down your enamel through my continuous drinking of acidic and hot drinks. Sometimes I don't even brush you, you seem to be the first thing I neglect when life gets overwhelming.
Recently I have been flossing more than ever and plan to brush much more regularly. You are a piece of me, and I am a piece of you. I am grateful for you and the state you are in, even if you are now much more vulnerable and weaker due to my poor habits. I hope to make each tooth live a little longer than they were going to, extending your life as much as I can. | 0non-cybersec

Option clash xeCJK and fontspec. <p>I need to load the <code>fontspec</code> package with the <code>no-math</code> option while also loading the <code>xeCJK</code> package to include a few Japanese names in a large English document. Since the<code>xeCJK</code> package already loads the <code>fontspect</code> package without any options, I am running into problems. More precisely, the code</p>
<pre><code>\documentclass{scrbook}
\usepackage{xeCJK}
\usepackage[no-math]{fontspec}
\begin{document}
\begin{CJK}
角谷静夫
\end{CJK}
\end{document}
</code></pre>
<p>results in an option clash for the <code>fontspec</code> package whereas the code</p>
<pre><code>\documentclass{scrbook}
\usepackage[no-math]{fontspec}
\usepackage{xeCJK}
\begin{document}
\begin{CJK}
角谷静夫
\end{CJK}
\end{document}
</code></pre>
<p>results in the following error:</p>
<pre><code> LaTeX Error: Environment CJK undefined.
</code></pre>
<p>Is there a way around this? I would also be happy with a solution to include snippets of Japanese using other packages than <code>xeCJK</code>.</p>

Connection between the positive part of a Sobolev function and its trace. <p>Assume that $u\in W^{1,1}(\Omega)$, where $\Omega$ is a bounded domain in $\mathbb{R}^n$ having regular enough boundary (say Lipschitz). Then it is well known that also $u^+\in W^{1,1}(\Omega)$.
Naturally, one could expect that $\mathrm{Tr}\, (u^+) = (\mathrm{Tr}\, u)^+$, but, to my surprise, I haven't found such a result in any book.</p>
<p>So I was wondering if this is true at all and if so, whether there is some reference for it.</p>
<p>Thank you very much for any help</p>

ObGyn recommended I look into freezing eggs as an option.. I'm turning 34 at the end of the summer, and I'm single with no one on the horizon. Even if I were to meet The One tomorrow and we follow the "traditional" route to establishing a family, the earliest I'll have a baby is 36 years old. I want at least two kids, so that takes me closer to 40. So far, everything else is healthy and I'm nowhere near menopausal, she's only recommending it because of the time horizon...
Has anyone else gone through this or have thoughts on the subject? I'm just weighing all my options for now.

higan says that OpenGL 3.2 is not available, but I should have 3.3. <p>I am running Trusty with gnome in crouton on a Toshiba Chromebook 2. I installed higan, and it reports: "Error: OpenGL 3.2 is not available."

Incremental File Backup With Super Easy End User Restore Interface?. <p>Don't ask why. I need to devise an incremental file backup solution (writing to a USB attached disk array) that has a super easy interface to allow any end user (like even a receptionist) to restore a version of any file to their local workstation.</p>
<p>My initial thoughts would be to devise a solution that stores the last 10 versions (or all versions in the last 30 days) in the same target folder but with an incremental number appended to the filename (filename_1.ext filename_2.ext). The end user can see the filenames date-time to determine when that version was created. The end user could browse the files via a mapped drive in Windows Explorer using SAMBA. I can think of anything easier for the user than that.</p>
<p>Here's some potential challenges on the server side that may need to be addressed:</p>
<ul>
<li><p>Frequency of backup related to performance. We're talking a data storage folder containing probably 100,000 files and 5TB of data. The incremental backup needs to be run at least once an hour. So it's got to be a solution that is architected to handle pretty large file collections. I'm anticipating this may not be an issue though as the volume of file changes is low, maybe 100 files change every hour at most.</p></li>
<li><p>Data duplication. Yes, storage is cheap, but with multiple versions the back storage requirement will be large. I don't think it's possible to have data de-duplication and let the end user be able to browse versions of files with a simple SAMBA file share. (Looked into RDIFF and you need to run the rdiff command to restore.) </p></li>
</ul>
<p>So I'd be open to a solution (free or low-cost) that instead of the users mapping a drive to the backup folder, they could bring up a web interface to browse the files and download as needed. Not quite as simple as mapping a drive but this would allow the backend to handle rebuilding a file version. </p>
<p>Any suggestions on solutions?</p>

mod_rewrite rules logging "Config variable ${REQUEST_URI} is not defined" on every request. <p>I have the following .htaccess on an Apache/2.4.2-win32 server:</p>
<pre class="lang-none prettyprint-override"><code># Turn mod_rewrite on
RewriteEngine On
# Allow direct loading of files in the static directory
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^/?static/(.+)$ - [L]
# Send all other requests to controller
RewriteCond ${REQUEST_URI} !^/?(spf/index\.php)?$
RewriteRule .* spf/index.php [L,QSA]
</code></pre>
<p>This works well and does exactly what I want it to. For those of you who can't be bothered working out what it does, it sends all requests through <code>spf/index.php</code> unless they are for a file that exists in the <code>static</code> directory.</p>
<p>The file resides in the virtual host's documentroot.</p>

</code></pre>
<p>This is not actually causing a problem - every request works as expected - but it's filling up my error log and I don't like it.</p>

Transition probabilities for a nonlinear state space model. <p>I am trying to compute the transition probabilities of the model given by
$X_{n+1} = f_{n+1}(X_n,W_{n+1})$ where $X_n's, W_n's$ are $R^k$ valued random variables for $n \geq 0$, $W_n's$ are independent and $f_n's$ are measurable. Also, define $\mathcal{F}_n=\sigma(X_0,W_1,\cdots,W_n)$. (From this definition
we get that $X_n$ is $\mathcal{F}_n$ measurable).</p>
<p>From these <a href="http://www.uni-bonn.de/~eberle/MarkovProcesses/MPSkript.pdf" rel="nofollow">notes</a>, the transition probabilites are defined as</p>
<p>$$p_{n+1}(X_n,B) := P[X_{n+1}\in B|\mathcal{F}_n]$$</p>
<p>Is it true that
$$ P[X_{n+1}\in B|\mathcal{F}_n] (\omega) = P[f(X_n(w),W_{n+1})\in
B]~a.s. $$ </p>
<p>If so, what is methodology for the proof and if not, what are the transition probabilites for this model?</p>

Is there any way to farm the Wendigo solo?. I've already finished the kills part of it, just need multi-kills and points. My problem is I've looked up ways to farm it and it seems like the all require you to load in with a group so you can just farm kills, whether it be lost sectors or well. The thing is I don't have a fireteam to run with so I'm stuck running regular strikes and its so much harder to get kills this way because blueberries just go through and kill everything. so it makes getting points hard and getting multi-kills even harder.

libinput button scrolling: delay between button press and scroll. <p>I'm using libinput to enable "button scrolling" for my trackball, where holding a specific button down causes ball movement to translate to scroll movement.</p>
<pre><code>xinput set-prop $TRACKBALL_ID "libinput Scroll Method Enabled" 0, 0, 1
xinput set-prop $TRACKBALL_ID "libinput Button Scrolling Button" 8
</code></pre>
<p>However, there's a delay of probably a few hundred milliseconds between pressing the button and scroll-translation starting. The timeline goes like this:</p>
<pre><code>+---+---+-------
^ ^ ^
| | +-- scrolling starts
| +-- start moving ball
+-- button down
</code></pre>
<p>It doesn't matter when I start moving the ball — the point is there's a fixed delay between "button down" and "ok, ready to translate movement to scroll".</p>
<p>It seems that this delay exists to enable dual-mode button use. If I just press and release the button quickly, its normal function (browser "back" button) is executed.</p>
<p>(Interestingly, the cursor is rendered stationary immediately upon pressing the button, even before scroll output begins.)</p>
<p>Is there a way to configure this delay? I'm perfectly happy to sacrifice the dual-mode use if necessary. Even if not configurable, who defines this constant and where? Perhaps I can get it changed in source.</p>

How do you find system manufacturer/model on Linux without root access?. <p>I'm working on a module for <a href="http://www.cs.wisc.edu/condor" rel="nofollow noreferrer">Condor</a> that will collect hardware information so that we can use realistic numbers to compute power savings, etc. The difficulty is that I don't maintain most of the client systems, so I have to write this with no assumptions as to what may or may not be installed on the system and I can't do anything that requires root access.</p>
<p>I've looked at various utilities (lshal, lshw, hwinfo, etc) and none of them seem to be universal across both Debian- and RedHat-based systems. I have neither the authority nor the desire to force other departments on campus to have one of those packages installed. </p>
<p>dmidecode seems to be pretty universal, but it's not helpful without root privileges. I haven't been able to find any files in /proc that contain the system manufacturer and model.

Group action on a subset. <p>having trouble with this problem. It's homework. We're given a finite set $S$ on which a finite group $G$ acts on transitively. If $U$ is a subset of $S$, I'm supposed to show that the subsets of $gU$ cover $S$ evenly. By evenly, I mean that each $s\in S$ is in the same number of sets $gU$.</p>
<p>Things I know are that for any $g,g'\in G$, $gU$ and $g'U$ both have order $|U|$. I also know that, since the operation is transitive, there is only one orbit (and I suspect this is important). </p>
<p>I also noticed that, when $|U| = 1$, this property is just the transitivity of the group action. I'm just having trouble generalizing this to where the sets overlap (ie, $s\in S$ is in more than one set $gU$.)</p>

Find $ \mathbb P \{ \max(X, Y) - \min(X, Y) \gt 0.2 \} $.. <p>Let $X$ and $Y$ be iid random variables for which $X \sim \text{Expo}(2)$ and $Y \sim \text{Expo}(3)$.</p>
<p>Find $ \mathbb P \{ \max(X, Y) - \min(X, Y) \gt 0.2 \} $.</p>
<p>SOLUTION:</p>
<p>There is a clever way to do this but, to convince myself, I tried to calculate it via "brute force," i.e., using convolution (or, rather, "cross-correlation," more specifically). However, I can't seem to get my answer to match with the given solution. Here's what I did:</p>
<p>Let $T \sim \{ \max(X, Y) - \min(X, Y) \} $. Then, $T \sim \lvert X - Y \rvert$, and so</p>
<p>$$ f_T(t) = \int_{0}^{\infty} f_X(t+y)f_Y(y)dy + \int_{0}^{\infty}f_X(y-t)f_Y(y)dy $$</p>
<p>$$ = \int_{0}^{\infty} 2e^{-2(t+y)} 3e^{-3y} dy + \int_{0}^{\infty}2e^{-2(y-t)} 3e^{-3y}dy $$</p>
<p>$$ = \frac{6}{5}\left(e^{-2t} + e^{2t}\right). $$</p>
<p>Now, for the survival function of $T$, we have</p>
<p>$$ \bar F_T(t) = 1 - \left[ \int_{0}^{t} \frac{6}{5}\left(e^{-2u} + e^{2u}\right) du \right] = 1 - \left[ \frac{6}{5} \sinh(2t) \right].$$</p>
<p>So, for our desired probability, we only need to evaluate $\bar F_T(0.2):$</p>
<p>$$\bar F_T(0.2) = 1 - \frac{6}{5} \sinh \left[ 2(0.2) \right] = 1 - \frac{6}{5} \sinh \left[ 2(0.2) \right] = 1 - \frac{6}{5} \sinh \left( 0.4 \right) \approx 0.5070972.$$</p>
<p>However, the provided solution states that</p>
<p>$$\bar F_T(t) = \frac{2}{5}e^{-3t} + \frac{3}{5}e^{-2t} $$</p>
<p>and so the solution is $ \approx 0.6217$.</p>
<p>Like I said, the provided solution goes about solving the problem in a much more clever (and quicker) way by conditioning on the cases in which $X \lt Y$ and $X \gt Y$, which I understand. My question here, rather, is why this brute force approach didn't work.</p>

<pre><code>> predict(mymod, dtest)

</code></pre>
<p>This makes sense to me, because with my <code>test</code> observation, I end up in the top leaf, which has a value of -0.1147.</p>
<p>Now I want to use <code>base_margin</code> to specify a set of initial values that I want to boost from. Suppose I set these values to 2 and predict on <code>test</code> again.</p>
<pre><code>dtrain2 <- xgb.DMatrix(as.matrix(train[, -1]), label = train[, "y"], base_margin = rep(2, nrow(train)))
mymod2 <- xgb.train(params = params, data = dtrain2, nrounds = 1)
xgb.plot.tree(model = mymod2)
> predict(mymod2, dtest)
[1] -0.1938634
</code></pre>
<p>Now the tree is different because of the <code>base_margin</code> specification. The prediction is simply the leaf output, -0.1938634, but why is it not 2 + (-0.1938634) because I thought <code>base_margin</code> is specifying the baseline predictions for <code>mymod2</code> to boost from?
<a href="https://i.stack.imgur.com/noo9P.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/noo9P.png" alt="enter image description here"></a></p>
<p>Would it be correct to specify <code>base_margin = 2</code> for my testing observation? i.e.</p>
<pre><code>dtest2 <- xgb.DMatrix(as.matrix(test), base_margin = 2)
> predict(mymod2, dtest2)
[1] 1.806137

<p>This gives me 2 + (-0.1938634) = 1.806137</p>

Approximation of a function and second derivative. <p>While solving some exercise I came up with this problem:</p>
<blockquote>
<p>Assume that <span class="math-container">$f \in C^2[0,\infty]$</span> (i.e. <span class="math-container">$f$</span> has continuous second derivative on <span class="math-container">$[0,\infty)$</span> and there exists limit in <span class="math-container">$+\infty$</span> of <span class="math-container">$f$</span>) be such that <span class="math-container">$f''(0) = 0$</span>.</p>
<p>Does there exist a sequence <span class="math-container">$(f_n) \subset C^2[0,\infty]$</span> such that <span class="math-container">$f_n \to f$</span> and <span class="math-container">$f''_n \to f''$</span> in the supremum norm (i.e. <span class="math-container">$\lVert f_n - f \rVert_{C[0,\infty]}$</span>, <span class="math-container">$ \lVert f''_n - f'' \rVert_{C[0,\infty]} \to 0$</span> ) and all <span class="math-container">$f_n$</span>'s satisfies <span class="math-container">$f''_n(0) = f'_n(0) = 0$</span>?</p>

<p>Maybe I am wrong but I think it would be nearly enough to approximate in that sense linear (in some neighborhood of <span class="math-container">$0$</span>) functions.</p>

In multiple tables, how to align columns again after variable-width columns?. <p>There are multiple (e.g., 2) tables that contain similar information. Between them is one table row of white space. </p>
<p>All tables have 3 columns. The first two columns belong together, which is why the second column has no heading. There should be a <code>\qquad</code> of white space between the longest text in the first column and the leftmost character of the second column. (It's ok to seek out the longest text manually and add the <code>\qquad</code> manually, like below.)</p>

ML350p Gen8 with non HP SSD. <p>I have a HP ML350p Gen8 which I am looking to upgrade. I have seen this Kingston data centre SSD:</p>

<p>Though this should work (with the right SFF caddy) I have seen old (4yrs+) posts where the fans go into a high speed mode if they detect non HP drives as the temperature can't be checked. Is this still an issue? I can't find any HP SSD compatibility checker.</p>

[Progress] From 6'4, 280lb Highschool lurch To 200lb gym addict.. Album: http://imgur.com/a/jDT5g ( I'm clueless as to posing, dont laugh too much!)
Greetings Fittit, this is my first post to your sub. I'm a longtime viewer just usually too nervous to post. But I see everyone on here with great physiques inspiring others, and I want to share my story, and hopefully inspire others as well!
I guess to start things out growing up I was a normal kid, probably on the small side until freshman year of high school. That's when I shot up and round. At my heaviest I was 280lbs. As evident by the first picture. I attribute it to a lot of soda and World Of Warcraft. Luckily when I got out of high school I got a job outside and started shedding weight, while keeping my soda drinking, WoW playing lifestyle. I kept that up until about 2012, when I was planning a cruise, and riding around on the forklift at work made my whole upper body jiggle. Decided I had enough. I quit sodas cold turkey and did a ton of cardio. That let the weight fly off me and kept me around 210lbs. Around January 2014 the weight lifting began and I absolutely FELL IN LOVE.
Fast forward a few years and here we are. Up until April of this year I didn't take my diet into consideration and just did whatever. Boy that was the biggest mistake I made. I realized after I started counting calories and macros that I could have been SO much farther along had I did my diet correctly the entire time. Which is one thing I hope you guys can pick up on. After I started tracking my macros and calories everything changed. It's like my body was getting noob gains again. My plateau was shattered. Lifts started getting higher, body started looking better. Diet is paramount to a great physique and I just though people were exaggerating.
Also, If anyone is interested I can share all my Diet / Macro info and my workout plan and a lot more detail when I get a chance in the morning.
EDIT: Wow! This got a bit more attention than I anticipated. I'll try to post everything relevant to help out.
Diet and macros seem to be what most people are interested in. Currently I'm in a cut, if anyone is interested or if it helps i use MyFitnessPal to track everything, and my profile is
http://www.myfitnesspal.com/food/diary/noneyabidness1
If you can't view that profile or dont want to make an account. My typical day in a short form goes like this. (Copied from MFP)
Breakfast
Sargento - Lite String Cheese, 2 piece string cheese
Food Should Taste Good - Multigrain Tortilla Chips, 28 g
Milk - Reduced fat, 2% milkfat, 1.5 cup
Peanut Butter and Co - White Chocolate Wonderful, 1 Tbsp (32g)
Great Value - Rolled Oats, 0.75 cup
365 Organic - Cinnamon Squares Cereal, 1 cup
Myprotein - Impact Whey Vanilla Raspberry, 125 g (5 scoops)
Lunch
Sweet Baby Rays - Original Bbq Sauce, 1 tbsp
Dannon - Light & Fit Greek - Dannon 2x Protein Peach, 2 container (150g)
Protein - Chicken Breast Skinless Boneless, 8 ounce
Birds Eye - Protein Blend Southwestern Style, 1 cup
Dinner
Myprotein - Impact Whey Protein_strawberry cream, 50 g (2 scoops)
Snacks
Bear Naked - Oats and Honey, 0.25 cup
Bananas - Raw, 1 medium (7" to 7-7/8" long)
Daisy - 2% Cottage Cheese, 226 g
Ghirardelli - 60% Cacao Bittersweet Chocolate Chips, 16 chips
Right now I'm at 2,750 calories per day, with a 35% / 25% / 40% split on carbs/fat/protein(241C / 76F / 275P).
My preferred protein powder is https://us.myprotein.com . For as much as I take their prices are insane, and they have great tests from labdoor. Highly recommend. I take Optimen Multivitamin and fish oil. For pre workout my preferred is either Pre-Jym or MP Assault / BPI sports 1.M.R. And I'm using Bulk-Supplements Creatine Mono.
If you'll notice on the MFP profile. I take on average 4-8 scoops of protein per day. People all have differing opinions. But this is what works for my situation. I believe that protein is protein whether it comes from a powder or a chicken breast and the only thing you dont gain from taking powder is the micro-nutrients in actual food, but I supplement with a few vitamins and I feel great.I can barely stand to eat chicken anymore so I supplement my diet with protein powder.
I probably still dont eat the best, but I get really close to my macros every day. I'm very strict on my diet, but I got some pretty good genetics from my dad (who is only 6'0) so that helps me a good bit.
Workout Plan:
For the past few months I've been following Layne Norton's PHAT program
http://www.simplyshredded.com/mega-feature-layne-norton-training-series-full-powerhypertrophy-routine-updated-2011.html
Fair warning though. It was a grueling workout starting out. But I've adjusted. I'll usually keep the main lifts the same as what he has but I'll change the accessory work every couple weeks or so. Pretty simple really. Another thing that might be surprising is that I do ZERO cardio. I can't stand it. I want to , and I probably need to.
A few people have asked for my lift stats. Well being on a cut my lifts have suffered a slight bit But staying close to the same weight, just doing less reps has helped me keep size on a cut. And I very rarely max. But my stats from about 3 weeks ago are--
Benchpress- 280 lbs 2 reps
Squat-(Leg got pulled into machinery and got messed up in 2011)- 315 lbs 1 rep
Deadlift- 405 lbs 2 reps
Overhead press 185lbs 1 rep.
I hope theirs adequate information in the edit. Please let me know if I can answer any more questions!

How to reorder included pdf-pages for bulk cutting ? [for paper saving]. <h1>How to reorder included pdf-pages for bulk cutting ? [for paper saving]</h1>
<h3>Situation and Problem</h3>
<p>I receive continuously updated lecture scripts as (A4) PDFs that I need to print.
The text area apparently fits onto A5 paper due to the large margins (that are usual with default LaTeX-documents).
In order to save some paper, I would like to print these A4 files as A5 but without resizing them (things become too small), but rather cutting edges.
Since I don't know how many pages this will be in the end, I can not use <code>signature</code>.</p>
<p>I know that this is bad from an aesthetical standpoint.</p>
<p>In the MWE below you can see, that I am trimming the included pages (try to use not <code>nup=1x2, landscape</code> but <code>frame, noautoscale</code>) from margins I found with <code>\layout</code> command.
However, I am unable to rearrange the order of the <code>nup=1x2</code> pages such that I could cut them in bulk and get ordered usual A5 sheets.
Later on I want to cut the pages and manually either glue- or hole-punch-bind them together.</p>
<h3>Question</h3>
<blockquote>
<p>How to reorder included <code>pdfpages</code> with <code>nup=1x2, landscape</code> to get bulk cut-able A5 pages?</p>

<p>Let me show the desired order with an adapted scheme from <a href="https://tex.stackexchange.com/questions/60934/how-to-sort-the-order-of-pages-so-that-they-can-be-printed-in-a-folded-book">here (please give Village credit)</a>.

I just don't get what's wrong with me. Why can't I make real friends? Why does it feel like people ignore me?. I honestly wish someone could watch how I interact with people on a day to day basis and tell me what I could be doing wrong. As far as I know, I'm not doing anything wrong. But for some reason, people just act weird around me sometimes. And I can never manage to maintain any friendships.
I work as a cashier, and a lot of times, I'll have a pleasant interaction with a customer, and then at the end when they're leaving and I wish them a good day, suddenly, they seem to get all cold and say "You as well" instead of "You too". I know I might be reading too much into it, but it just seems like a distant and less friendly thing to say than the latter.
I just don't know, guys. All I want is to change. That's what I've wanted for 10 years now, and it just never seems to happen, no matter what I read or if I do anything to change my behavior. | 0non-cybersec

What do you call the term in a sequence that has a number as its primitive divisor?. <p>I have seen different things from difference sources. For example, in "Factorizations of <span class="math-container">$b^n\pm 1$</span>", the rank of N is used to mean the first term in <span class="math-container">$b^n-1$</span> it divides. Is this unique to this sequence because it would be synonymous with multiplicative order in this case?
For example, <a href="https://stackoverflow.com/questions/9223901/what-is-position-in-terms-of-a-sequence">https://stackoverflow.com/questions/9223901/what-is-position-in-terms-of-a-sequence</a>, states that rank refers to the number of terms less than a number in a sequence. Also in this link, it says that "position" refers to the position specific number in the sequence, of course, but not necessarily the first term a number <span class="math-container">$N$</span> <span class="math-container">$divides$</span>. </p>
<p>Edit: If there is no ubiquitous term for this, could I simply call it a <span class="math-container">$primitive$</span> <span class="math-container">$index$</span>, as it refers to the term for which a number is a <span class="math-container">$primitive$</span> <span class="math-container">$divisor$</span>? Or is this somehow incorrect or ignorant-sounding? </p>

Cardinality of the following sets. <p><a href="https://i.stack.imgur.com/7YRJg.png" rel="nofollow noreferrer">Cardinality of set question</a></p>
<p>Please Correct if I am wrong at any point since at some points I must go wrong in my basic understanding of the question and data.</p>
<p>My understanding of this is that set A={1,2,3..,n} refers to a set, A, having n number of natural numbers in order for example if n=5 A={1,2,3,4,5} and if n=10 A={1,2,3,4,5,6,7,8,9,10}. The Cardinality of a set is the number of elements in the set for example if n=5 set A has a cardinality of 5 and etc.</p>
<p>For the question itself my understanding is that they've defined a set {a,S} such that, a, is a member of, S, and, S, is a member of the power set of, A, and I'm supposed to find the number of elements in this set. My current understanding is: The Cardinality of P(A) is 2^n. S, is a member of P(A) so therefore should have the same cardinality and, a, is a member of, S, and so should have the same cardinality making the overall set have a cardinality of 2^2n.</p>
<p>However this answer is completely wrong, the answer says that there a n choices for a and 2^(n-1) choices for S since we can choose the set of S \ {a} in 2^(n-1) ways giving us the answer of n2^(n-1).</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>

Instead of paying the MPAA/RIAA millions of dollars with no results, why doesn't the entertainment industries just bill/invoice the downloaders for the things they downloaded?. Instead of trying to sue / bankrupt citizens / their potential customers, why doesn't the property right owner just invoice them for what they download MSRP? If I got caught a couple times I would just say, "Fuck it, I'm just going to buy the movie cheap on amazon or get a netflix account." They pay these asshats boatloads of money to "protect" their licenses but most of the time they don't get paid or they literally ruin someone's life.
I realize that there are a lot of technical things I don't understand and that entertainment companies have to take a hard / ignorant stance on piracy due to their old ass CEO's etc, but I personally feel like this is a compromise from both sides. People who are more tech savvy will still get away scot-free, single mothers won't be fined $200k for 20 songs and the companies could add to their bottom line. I know it's a little naive to thing that a mega-corp would do this, but it seems pretty reasonable to me.
And hey, now those dudes selling DVD's on the street corner will make some extra bucks now too!
edit: forgot to ask what everyone's opinion / reservations on this are. Tell me where I'm wrong.

Is static universally "evil" for unit testing and if so why does Resharper recommend it?. <p>I have found that there are only 3 ways to unit test (mock/stub) dependencies that are static in C#.NET:</p>
<ul>
<li><a href="http://research.microsoft.com/en-us/projects/pex/" rel="noreferrer">Moles</a></li>
<li><a href="http://www.typemock.com/typemock-isolator-product3/" rel="noreferrer">TypeMock</a></li>
<li><a href="http://www.telerik.com/products/mocking.aspx" rel="noreferrer">JustMock</a></li>
</ul>
<p>Given that two of these are not free and one has not hit release 1.0, mocking static stuff is not too easy.</p>
<p>Does that make static methods and such "evil" (in the unit testing sense)? And if so, why does resharper want me to make anything that can be static, static? (Assuming resharper is not also "evil".)</p>
<p><strong>Clarification:</strong>
I am talking about the scenario when you want to unit test a method and that method calls a static method in a <em>different</em> unit/class. By most definitions of unit testing, if you just let the method under test call the static method in the other unit/class then you are <strong>not</strong> unit testing, you are <em>integration</em> testing. (Useful, but not a unit test.)</p>

Tracking eye pupil in camera preview, with most watched part of the screen. <p>I have live camera preview, now project requires eye pupil movement tracking (which is different from Eye is open/close). Means which part of the screen is being seen by the user this time and what is the most viewed part of screen at the end of Video stream. Although, I tried with OpenCV & Google Vision api, but they are not able to perform the task perfectly.
Please suggest if you have any solution.</p>

How do you convert a Rails 5 API app to a rails app that can act as both API and app?. <p>I initially created it in rails 5 with the --api tag.</p>
<p>From <a href="http://edgeguides.rubyonrails.org/api_app.html" rel="noreferrer">http://edgeguides.rubyonrails.org/api_app.html</a>,</p>
<p>I removed <code>config.api_only = true</code></p>
<p>I changed </p>
<pre><code>class ApplicationController < ActionController::API
end
</code></pre>
<p>to</p>
<pre><code>class ApplicationController < ActionController::Base
end
</code></pre>
<p>The problem I'm having now is when the view is getting rendered, ex. <code>welcome/index.html.erb</code>, the corresponding CSS file <code>assets/stylesheets/welcome.css.scss</code> is not.</p>
<p>Any idea how I can fix this, or more generally convert the API application to a full app?</p>
<p>Thanks!</p>

Do first impressions really count?. <p>So, i am currently writing something up for a college class. Problem is everything is hypothetical. I need some proof. I believe a first impression on a website is imperative so that people actually use it and in my case, buy your product or services as well.</p>
<p>Basically I'm wondering has there been any studies that shows how a better web design will increase revenue for any kind of services? I don't just mean selling products like a T-shirt, but labor services as well. </p>
<p>If someone wanted their computer fixed and searched for companies that can do so, will a first impression on the website help them make their decision to use your company? Are there any studies like this? White papers maybe?</p>

Branch names not showing in Mercurial's tab completion. <p>I have a development machine running mercurial 1.6.3. Tab completion in bash works great for completing commands, tags and branch names. I've set up a new machine with the same mercurial version (both running python 2.6), but when I try to use tab completion, I only get hg commands and tags to show - no branch name. Is there anything I need to configure to have branch names included as well? thanks.</p>

How do I convince programmers in my team to do TDD?. <p>I am aware of this question: <a href="https://stackoverflow.com/questions/428691/how-to-encourage-implementation-of-tdd">https://stackoverflow.com/questions/428691/how-to-encourage-implementation-of-tdd</a></p>
<p>In my team, we write a lot of unit tests. But, in general the programmers tend to write unit tests after wrting the code. So, we first finish the module functionality and then write tests. Our coverage is around 70% for most modules. I have tried convincing my technical manager and my team members to do pure TDD wherein we first write tests and then the code, but invain. I think writing tests first allows us to discover design better. Am I just being finicky, especially when our coverage is quite high? If the answer to this question is no, then how do I talk to people to have a test-first approach.</p>
<p><strong>EDIT:</strong> I think writing tests after writing code is an easier thing to do. People in my team have got accustomed to do this and are opposing any change.</p>

I'm singer and songwriter Kat Edmonson- ask me anything about my album Old Fashioned Gal and about other stuff- AMA!. I am a singer and a songwriter. I released a new album on Friday, April 27 called Old Fashioned Gal. It's my fourth record. I wrote and produced it and it's my version of a soundtrack to a musical from the 1950s. Incidentally, I wrote an outline for a screenplay to go with the album (in case somebody feels like making a musical for film with me!). I travel around the United States and the world singing my music. Sometimes, I throw in a jazz standard or two to my set because I love the Great American Songbook and those songs go well with my songs. I call my music vintage pop. I've been in a couple movies: Angels Sing which is always on The Hallmark Channel around the holidays and Woody Allen's Cafe Society. I love acting. I plan to do more.

Finding the value $h, $ given $f(x,y) = \frac{sin (x-y)}{x-y}$. <p>I was studying for some quizzes when I stumbled upon this question:</p>
<p>The function $f(x,y) = \frac{sin (x-y)}{x-y},$ $x$ is not equal to $y,$ and $f(x,y) = h,$ $x = y$ is continuous.
What is the value of $h$?</p>
<p>My work:</p>
<p>I noticed that the answer found in my book is $h = 1,$ so I think I can get $h = 1$ by doing this:</p>
<p>$$lim_{{x->0}\space and \space {y->0}} \frac{sin (x-y)}{x-y} = 1$$</p>
<p>because everybody knows that</p>
<p>$$lim_{x->0} \frac{sin x}{x} = 1$$</p>
<p>Is my train of logic correct?</p>

Finally below 200lbs!. 18 year old male; 6''1 uni student.
When I started university in September of last year I was 220lbs, but now 4 months later I am 199lbs. It feels good. I definitely tripped up a lot along the way; I was horrible at counting calories and the binge drinking definitely slowed it down.
But now that I'm far more aware of the calories, going clubbing less and hitting the cardio more, I have finally cut down to below 199lbs.

<p>How Can We convert the Whole ODataQueryOptions to a Linq expression query (regardless of what is passed in), this resource is only for the filter, <a href="https://stackoverflow.com/questions/16445062/how-to-transform-odata-filter-to-a-linq-expression">How to transform OData filter to a LINQ expression?</a></p>
<p>DBContext-->DomainLayer-->Dto--> Then API Level,</p>
<p>The two middle layers. Mappers map from EF DBContext to Domain to Dto.</p>
<p>Repository methods bring data.</p>
<p>AppService Methods converts to Dto.</p>
<p><strong>Current Solution with ProjectTo:</strong></p>
<p><strong>Controller API:</strong></p>
<pre><code>[HttpGet]
public async Task<ActionResult<IList<AddressTypeDto>> GetAddressAPI(ODataQueryOptions<AddressTypeDto> queryOptions)
{
return Ok(await _service.GetAddressTypeDto(queryOptions));
}
</code></pre>
<p><strong><strong>Application Service:</strong></strong></p>
<p>(How can we apply ODataModelBuilder mapping in Startup here?)</p>
<pre><code>public async Task<AddressTypeResponse> GetAddressTypeDto(ODataQueryOptions<AddressTypeDto> queryOptions)
{
var dto = (IQueryable<AddressTypeDto>)queryOptions.ApplyTo(_addressRepository.GetAddressTypes().ProjectTo<AddressTypeDto>(_mapper.ConfigurationProvider));
var dtoList = await dto.ToListAsync();
return dto;
}
</code></pre>
<p><strong><strong>Repository:</strong></strong></p>
<pre><code>[EnableQuery]
public IQueryable<LkAddressType> GetAddressTypesData()
{
return _ctx.LkAddressType.AsNoTracking();
}
</code></pre>
<p><strong>Classes:</strong></p>
<pre><code> public class AddressTypeDto
{
public int AddressTypeId { get; set; }
public int? LastModifiedByUserId { get; set; }
public string AddressTypeCode { get; set; }
public string AddressTypeDescription { get; set; }
public bool? Status { get; set; }
public DateTime? CreateDate { get; set; }
}
public LkAddressType()
{
public int LkAddressTypeId { get; set; }
public int? LastModifiedByUserId { get; set; }
public string AddressTypeCode { get; set; }
public string AddressTypeDescription { get; set; }
public bool? Status { get; set; }
public DateTime? CreateDate { get; set; }
public DateTime? EffectiveStartDate { get; set; }
public DateTime? EffectiveEndDate { get; set; }
}
</code></pre>

Maximize, Minimize, Exit in the global menu. <p>When I have a program like Firefox and the terminal maximized I have the minimize, maximize and exit controls in the global menu (at the top).</p>
<p>I really don't like it, is it possible to get it to the program like in GNOME or Windows?</p>

Glob not giving me any results. <p>I'm trying to use PHP's Glob to get a list of files based on a wildcard, namely the extension.</p>
<pre><code>$images = glob('/content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);
</code></pre>
<p>I know there is a file in this directory, namely: 23.png but it doesn't show in array $images. I don't have a clue why not. I've tried making the URL even more absolute (or explicit) like:</p>
<pre><code>$images = glob('http://www.website.com/content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);
</code></pre>
<p>Without result.</p>
<p>Could it be that Glob isn't installed properly inside PHP? Or is there another reason this doesn't give any results?</p>

Translate local url address to full url. <p>I have a configured <code>VPN</code> that let's me work from home, but I can not access the remote tools as I do when I am at work, example:</p>
<p>At work I can type to a browser:</p>
<pre><code>jenkins/
</code></pre>
<p>from home I have to add an extension to the domain name:</p>
<pre><code>jenkins.local.private
</code></pre>
<p>Is there a way to make the first one work from home too? knowing that this is just an example, I want a general solution.</p>
<p>Thanks</p>

The band Bad Company has a song titled 'Bad Company' on their album Bad Company. Can you name others like this?. The only other instance I can think of is Iron Maiden, who has a song titled 'Iron Maiden' on the album Iron Maiden. Can anybody name others?
EDIT: Holy Cow, I was away for a few hours and I cannot believe how many people commented! I also didn't realize how many of these songs I actually own! Keep it going everybody!! | 0non-cybersec

Invalid time on FreeBSD. <h1>Problem</h1>
<p>My FreeBSD is always 2 hours behind when I'm offline although my BIOS clock shows the UTC time and my time zone is set to CET in /etc/localtime.</p>
<p>I'd like FreeBSD to look at the clock in BIOS, assume that it is UTC, check what time zone is chosen and then set the time on the machine accordingly.</p>
<hr>
<h1>Details</h1>
<p>I've already tried removing <code>/etc/wall_cmos_clock</code> and running <code>adjkerntz -a</code> after I changed <code>machdep.adjkerntz</code> with <code>sysctl</code> from <code>-7200</code> to <code>0</code>. I rebooted the machine several times in different configurations during that process. </p>
<p>I am not interested in solutions utilizing the ntpd utility as it requires an Internet connection.</p>
<p>It is a dual boot system. The second system is Ubuntu 17.04 and it is its GRUB which boots FreeBSD via chain loading.</p>
<h2>Workaround</h2>
<p>I couldn't find any solutions online so I decided to change the time manually with <code>date(1)</code>.</p>
<pre><code># date +%H%M
1426
# date 1626
</code></pre>
<p>I'd love to know if there is a better solution however.</p>
