53,868,770 | I simply want to use a modified example of Nested flex on the [PrimeNG Flex](https://www.primefaces.org/primeng/#/flexgrid) by using the code below:
```
<h3>Nested</h3>
<div class="p-grid nested-grid">
<div class="p-col-8">
<div class="p-grid">
<div class="p-col-6">
<div class="box">6</div>
</div>
<div class="p-col-6">
<div class="box">6</div>
</div>
<div class="p-col-12">
<div class="box">12</div>
</div>
</div>
</div>
<div class="p-col-4">
<div class="box box-stretched">4</div>
</div>
</div>
```
However, the col divs act as the total size is not 12, instead 11 and if the total p-col number is 12 or more, the elements wrap to the next row that I do not want. On the other hand, I have a look at all of the main divs and body paddings and margins but there is no problem with that. I think the padding of the p-cols does not causing this problem and their paddings are also 0-5 px range. Any idea how to fix this problem? | 2018/12/20 | [

] | the example in the site shows kind of like this
i don't think you need 'p-grid nested-grid'
```
<div class="p-grid">
<div class="p-col-8">
<div class="p-grid">
<div class="p-col-6">
6
</div>
<div class="p-col-6">
6
</div>
<div class="p-col-12">
12
</div>
</div>
</div>
<div class="p-col-4">
4
</div>
``` | To keep the `nested-grid` class in the first `div` element you can add the following to your global styles.css file to fix it.
```
* {
-webkit-box-sizing: border-box;
}
```
This will stop the col divs from acting as if the total size is 11 instead of 12 and works with all the examples shown on the primefaces website <https://www.primefaces.org/primeng/#/flexgrid> |
52,616,343 | I'm wondering if it's better practice to use Bundle or make another class entirely to save data?
During a fragment change I can set it up so that onSaveInstanceState() saves information. Alternatively, I could store that information as a static variable in another class, then create a getter function in that class and use it to "restore" the variables state under onCreateView().
I would much prefer to use another class as I feel like I have more control over the management of my data, but I'm not sure if this would cause any issues or if this is bad practice as I haven't seen any mention of people doing it this way. | 2018/10/02 | [

] | For the various steps, I can give you the following hints.
### File names
For obtaining mp3 file names the [glob](https://docs.python.org/3/library/glob.html) module is your friend: `glob.iglob('*.mp3', recursive=True)`.
### Dealing with mp3
For dealing with mp3 files you can use practically any command line utility that serves your needs. A few examples:
* [avprobe](https://askubuntu.com/a/249843/445311)
* [exiftool, ffmpeg, mplayer](https://askubuntu.com/a/303461/445311)
* [mediainfo](https://superuser.com/a/595205/742396)
You can run these tools from within python via the [subprocess](https://docs.python.org/3/library/subprocess.html) module. For example:
```
subprocess.check_output(['avprobe', 'path/to/file'])
```
Then you can parse the output as appropriate; how to detect if the file is broken needs to be explored though.
### Dive into mp3
If you're feeling adventurous then you can also scan the mp3 files directly. [Wikipedia](https://en.wikipedia.org/wiki/MP3#File_structure) gives a hint about the file structure. So in order to get the bit rate the following should do:
```
with open('path/to/file', 'rb') as fp:
fp.read(2) # Skip the first two bytes.
bit_rate = fp.read(1) & 0xf0
``` | For my purposes ideally fits [mutagen](https://mutagen.readthedocs.io/en/latest/index.html) here is [**solution**](https://m5-web.com/blog/165) with comments.
Everything is pretty simple. |
13,823 | I have installed MySQL via [homebrew](https://brew.sh/): `brew install mysql`. I'd like to get the MySQL preference pane hooked up to my installation of MySQL through homebrew. How can I achieve this? | 2011/05/09 | [

51,643,920 | Given these two classes:
```
public class Abc
{
public static void Method(string propertyName) { }
}
public class Def
{
public int Prop { get; }
public void Method2() { Abc.Method("Prop"); }
}
```
As is, Roslyn rule CA1507 (use nameof) will be triggered for `Method2`. I don't want that, because that string is used for long-term custom serialization and can never change (if we decide to change the name of `Prop` we won't be changing that string). I don't want to disable the rule on an assembly level or even class level. There are also hundreds of callers like `Def` so I want something that doesn't require me to do anything to the callers.
Is there some kind of [ExcludeParameterFromCodeAnalysis] I can put on the `propertyName` param to be excluded from all or some code analysis?
Here's the concept I hope exists, or some variant on it:
```
public class Abc
{
public static void Method([SuppressMessageForCallers("CA1507")]string propertyName) { }
}
public class Def
{
public int Prop { get; }
public void Method2() { Abc.Method("Prop"); }
}

So let's change the parameter:
```
public class Abc
{
public static void Method(string propertySerializationName) { }
}
```
---
1Even if you don't know or can guess at which specific analyzer implements a warning, it looks like searching the [roslyn-analyzers](https://github.com/dotnet/roslyn-analyzers) repository for the specific code (`CA1507`) should help you find them without too many false positives.
2Weirdly, it wouldn't even appear to trigger on a parameter called `parameterName`. | There's nothing that can be done to `Abc.Method` declaration regarding this warning because the warning is not on the method (or even on it's invocation) but on the literal itself.
It might be ugly, but it works:
```
public class Abc
{
public static void Method(string propertyName) { }
}
public class Def
{
public int Prop { get; }
public void Method2()
{
#pragma warning disable CA1507 - use nameof
Abc.Method("Prop");
#pragma warning restore CA1507 - use nameof
}
}
```

it hides the adMob banner **but** also the EdiText.

I learned how to detect if the keyboard opens [here](https://stackoverflow.com/questions/2150078/how-to-check-visibility-of-software-keyboard-in-android?page=1&tab=oldest#tab-top).
and here is my solution:
```

activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
if (heightDiff > Support.dpToPx(MainActivity.this, 200)) { // if more than 200 dp, it's probably a keyboard...
mAdView.setVisibility(View.GONE);
}
else{
mAdView.setVisibility(View.VISIBLE);
}
}
});

] | 1. As Kibbee suggests, the wrong size valve.
2. A badly-formed valve hole in the rim. It's not that unusual to find that there is a "lip" of metal at the hole that will cut into the tube. This requires a bit of filing with a small round file to correct.
3. Running the tire flat or with very low pressure. As an under-inflated tire rolls on the ground it tends to "walk" along the rim, tugging on the valve stem.
4. Poor tube installation technique. Most importantly, inflate the tube slightly before installing -- just enough that it rounds out (though it should still be limp). | The most likely cause is using a presto valve is a rim that's drilled for Schrader. Make sure you're using the correct tube for your rims. You can get a grommet to fill the hole if you want to use presto tubes on rims that are drilled for Schrader.
It might also be because the pressure was too low. This can cause the tire to be able to move around inside the tire, and would mostly occur during braking.
Check on the valve hole to make sure there aren't any rough edges, and file them down (only lightly, be careful) if the hole has any sharp edges. |

] | The identity of $G =\mathbb Q / \mathbb Z$ is $\mathbb Z$.
1) Every element of $G$ has **finite** order. Indeed, if you take any $r + \mathbb Z \in G$ where $r \in \mathbb Q$ then we may write $r = \frac{m}{n}$, with $m,n \in \mathbb Z $ and $n > 0$. Thus
$$n (r + \mathbb Z) = m + \mathbb Z = \mathbb Z$$
then it follows that $\left|r + \mathbb Z\right| \leq n$.
**Edit:**
2) The group has **infinite** order because we may choose an element in $G$ with arbitrarily large order, consider $\frac{1}{n} + \mathbb Z$, where $\left|\frac{1}{n} + \mathbb Z\right| = n$ (why?). | If the group is of finite order then the order of every element in the group divides the order of the group. Hence no element can have infinite order.
In your example, if $\dfrac {p}{q} +\mathbb Z \in \mathbb Q/\mathbb Z$ then $\left(\dfrac{p} {q} +\mathbb Z\right)^q =q\left(\dfrac {p} {q} +\mathbb Z \right) =\mathbb Z$ which is the identity element of this group. Hence every element is of finite order. |

Here, `gam` is used to evaluate how the temperature at New York and Miami vary from the mean temperature (of both locations) at different times of the day.

I eventually hope to display all of this information on one graph (for each location).

] | The "a" in "gam" stands for "additive" which means no interactions, so if you fit interactions you are really not fitting a gam model any more.
That said, there are ways to get some interaction like terms within the additive terms in a gam, you are already using one of those by using the `by` argument to `s`. You could try extending this to having the argument `by` be a matrix with a function (sin, cos) of doy or tod. You could also just fit smoothing splines in a regular linear model that allows interactions (this does not give the backfitting that gam does, but could still be useful).
You might also look at projection pursuit regression as another fitting tool. Loess or more parametric models (with sin and/or cos) might also be useful.
Part of decision on what tool(s) to use is what question you are trying to answer. Are you just trying to find a model to predict future dates and times? are you trying to test to see if particular predictors are significant in the model? are you trying to understand the shape of the relationship between a predictor and the outcome? Something else? | For two continuous variables then you can do what you want (whether this is an interaction or not I'll leave others to discuss as per comments to @Greg's Answer) using:
```
mod1 <- gam(Temp ~ Loc + s(Doy, bs = "cc", k = 5) +
s(Doy, bs = "cc", by = Loc, k = 5, m = 1) +
s(Tod, bs = "cc", k = 5) +
s(Tod, bs = "cc", by = Loc, k = 5, m = 1) +
te(Tod, Doy, by = Loc, bs = rep("cc",2)),
data = DatNew, method = "ML")
```
The simpler model should then be nested within the more complex model above. That simpler model is:
```
mod0 <- gam(Temp ~ Loc + s(Doy, bs = "cc", k = 5) +
s(Doy, bs = "cc", by = Loc, k = 5, m = 1) +
s(Tod, bs = "cc", k = 5) +
s(Tod, bs = "cc", by = Loc, k = 5, m = 1),
data = DatNew, method = "ML")
```
Note two things here:
1. The basis-type for each smoother is stated. In this case we would expect that there are no discontinuities in Temp between 23:59 and 00:00 for `Tod` nor between `Doy == 1` and `Doy == 365.25`. Hence cyclic cubic splines are appropriate, indicated here via `bs = "cc"`.
2. The basis dimension is stated explicitly (`k = 5`). This matches the default basis dimension for each smooth in a `te()` term.
Together these features ensure that the simpler model really is nested within the more complex model.

] | Have a look at `active_record_upsert` gem here: <https://github.com/jesjos/active_record_upsert>. This does the upsert, but obviously only on Postgres 9.5+. | You can achieve that by creating the SQL using the active records internals. You can use the `arel_attributes_with_values_for_create` to extract values for each active\_record for the insert sql with the Rails attributes, something like:
```
INSERT_REGEX = /(INSERT INTO .* VALUES) (.*)/
def values_for(active_record)
active_record.updated_at = Time.now if active_record.respond_to?(:updated_at)
active_record.created_at ||= Time.now if active_record.respond_to?(:created_at)
sql = active_record.class.arel_table.create_insert.tap do |insert_manager|
insert_manager.insert(
active_record.send(:arel_attributes_with_values_for_create, active_record.attribute_names.sort)
)
end.to_sql
INSERT_REGEX.match(sql).captures[1]
end
```
Then you can add all the values into one big "values" string:
```
def values(active_records)
active_records.map { |active_record| values_for(active_record) }.join(",")
end
```
For the insert part of the SQL you can use a similar code to the one used for the value extraction:
```
INSERT_REGEX = /(INSERT INTO .* VALUES) (.*)/
def insert_statement(active_record)
sql = active_record.class.arel_table.create_insert.tap do |insert_manager|
insert_manager.insert(
active_record.send(:arel_attributes_with_values_for_create, active_record.attribute_names.sort)
)
end.to_sql
INSERT_REGEX.match(sql).captures[0]
end
```
For the conflict part you can do the following:
```
def on_conflict_statement(conflict_fields)
return ';' if conflict_fields.blank?
"ON CONFLICT (#{conflict_fields.join(', ')}) DO NOTHING"
end
```
At the end just concatenate all of them together for execution:
```
def perform(active_records:, conflict_fields:)
return if active_records.empty?
ActiveRecord::Base.connection.execute(
<<-SQL.squish
#{insert_statement(active_records.first)}
#{values(active_records)}
#{on_conflict_statement(conflict_fields)}
SQL
)
end
```
You can check [here](https://gist.github.com/marcelorxaviers/9fc7ffeec007e497477cfc412de285bc) the final solution.
This is the output for me - using my **balance** active record model and removing the piece of code that executes the SQL(`ActiveRecord::Base.connection.execute...`):
```
> puts BatchCreate.perform(active_records: [balance], conflict_fields: [:bank_account_id, :date])
INSERT INTO "balances" ("amount", "created_at", "currency", "date", "id", "bank_account_id", "updated_at") VALUES (0, '2018-11-28 15:42:44.312954', 'MXN', '2018-11-28', 15169, 26300, '2018-11-28 16:05:07.465402') ON CONFLICT (bank_account_id, date) DO NOTHING

Just trying to get my head around some of composer's (probably applies to other package managers too) functionality.
Basically I just want to know what composer does in the following scenarios:
1.
My main project has a dependency:
```
"guzzlehttp/guzzle": "5.0.*",
```
My external bundle has a dependency on
```
"guzzlehttp/guzzle": "5.0.*",
```
Does composer install guzzlehttp/guzzle one time because it knows it only needs it once?
2.
Same scenario but in the future if someone updates the main project to use:
```
"guzzlehttp/guzzle": "6.0.*",
```
Will composer now install 2 versions of guzzle (5 and 6) (I presume this is what it should do), or will it take the highest version (i.e. 6)? Also if there are 2 versions will this cause any conflicts because namespaces might be the same?

] | ### To question 1
Yes Composer can only install one version of each extension/package.
### To question 2
Because of answer 1: Composer would consider your main project and the external package as incompatible.
In this case you could
* stay with version 5 at your main project too.
* ask the external package owner to upgrade to version 6 too if it's compatible to.
* fork the external package and make it compatible to version 6 yourself | We had a situation today where we were using multiple libraries, and one used Guzzle v5 and the other Guzzle v6. Upgrading (or downgrading) was not a viable option, as it was third party code, so we had to be able to install both versions of Guzzle.
Here's what we did. This is a **TOTAL FRACKING HACK**, and I'd advise doing this only as an absolute last resort. It works, but updating your calling code to use just one version is a much better option.
The trick is that you need to re-namespace one of the two versions. In our case we decided to change v6 to GuzzleHttp6. Here's how to do that:
1. Make sure your `composer.json` has v6 enabled:
```js
"require": {
"guzzlehttp/guzzle": "^6.2"
// possible other stuff
},
```
2. `composer install` to get Guzzle v6 all its dependencies installed.
3. Move the `/vendor/guzzlehttp` directory over to a new `/vendor-static/guzzlehttp` directory.
4. Do a case-sensitive find & replace on the `/vendor-static` directory to replace **GuzzleHttp** with **GuzzleHttp6**. This effectively brings the Guzzle 6 code into a new namespace.
5. Now update your `composer.json` to include Guzzle's own dependencies manually, and then autoload the code in the `/vendor-static` folder. Note you'll want to REMOVE the main guzzle require statement (or change it include guzzle 5);
```js
"require": {
"guzzlehttp/guzzle": "~5",
"psr/http-message": "~1.0",
"ralouphie/getallheaders": "^2.0.5"
},
"autoload": {
"files": ["vendor-static/guzzlehttp/guzzle/src/functions_include.php",
"vendor-static/guzzlehttp/psr7/src/functions_include.php",
"vendor-static/guzzlehttp/promises/src/functions_include.php"],
"psr-4": {
"GuzzleHttp6\\": "vendor-static/guzzlehttp/guzzle/src/",
"GuzzleHttp6\\Psr7\\": "vendor-static/guzzlehttp/psr7/src/",
"GuzzleHttp6\\Promise\\": "vendor-static/guzzlehttp/promises/src/"
}
},
```
5. `composer update` to remove the old Guzzle v6, and install Guzzle v5. This will also install the `psr/http-message` and `ralouphie/getallheaders` dependencies.
6. You may need to do a `composer dump-autoload` to force the autoloader to add the new include paths. In theory this should happen on `composer update` but I had to force it.
7. Now update your calling code; instead of calling **\GuzzleHttp**, you'll call **\GuzzleHttp6** .
And that's it. You should be able to run both concurrently. Note that whatever version of Guzzle v6 you've got in the `/vendor-static` directory will be there forever-more, so you may want to update that from time-to-time. |

or might it half-imply that "someone has *isolated* these lymphocytes from tissue", and thus the term is better avoided in this sentence for clarity's sake?

Again, this usage cannot refer to "isolated cases." This time because it's being used as an adjective to modify "peripheral blood lymphocytes."
These were the first three results when searching for the phrase"isolated peripheral blood lymphocytes," so I think it is safe to conclude that that phrase will only ever be interpreted to mean "isolated ... from tissue."

If you wish to express that staining was observed in only some of the lymphocytes, you might want to reword the sentence as:

If your intention was to say that slight staining was observed in those lymphocytes not clustered together, you might say:

You can't. You can only have one value per key in a Python dict. What you can do is to have a list or a set as the value.
Here is an example with a set:
```
d1 = { 'a': 1, 'b': 2, 'c': 3 }
d2 = { 'a': 1, 'b': 5, 'd': 4 }
d3 = {}
def add_dict(target, d):
for key in d:
target.setdefault(key, set([])).add(d[key])
add_dict(d3, d1)
add_dict(d3, d2)
```
This will give you `d3`:
```
{'a': set([1]), 'c': set([3]), 'b': set([2, 5]), 'd': set([4])}
```
You can also do this with a list (possibly closer to your example):
```
d1 = { 'a':1, 'b':2, 'c': 3}
d2 = { 'b':2 ,'c':3, 'd': 1}
d3 = {}
def add_dict(target, d):
for key in d:
target.setdefault(key, []).append(d[key])
add_dict(d3, d1)
add_dict(d3, d2)
```
You'll get this:
```
{'a': [1], 'c': [3, 3], 'b': [2, 2], 'd': [1]}
```
However, looking at `{'a':1,'b':2,'c':3,'b':2,'c':3,'d':1}` (which can't be a dict), it seems that you're after a different data structure altogether. Perhaps something like this:
```
d1 = { 'a':1, 'b':2, 'c': 3}
d2 = { 'b':2 ,'c':3, 'd': 1}
result = []
result += [ { 'key': key, 'value': d1[key] } for key in d1 ]
result += [ { 'key': key, 'value': d2[key] } for key in d2 ]
```
This would produce this, which looks closer to the data structure you had in mind initially:
```
[ {'value': 1, 'key': 'a'},
{'value': 3, 'key': 'c'},
{'value': 2, 'key': 'b'},
{'value': 3, 'key': 'c'},
{'value': 2, 'key': 'b'},
{'value': 1, 'key': 'd'} ]
``` | You may want to try:
```
D3 = {}
D3.update(D1)
D3.update(D2)

72,363,010 | How can I add random numbers (for example from 1 to 100) into an array using Julia language? Also, the array already has to have a defined length (for example 30 numbers). | 2022/05/24 | [

] | If your initial vector is `v`, you can do as follows:
```
v .+= rand(1:100,length(v))
```
* `rand(1:100,length(v))` will generate a random vector of integers between 1 and 100 and of length identical to `v`'s one (the `length(v)` part), you can read the [rand()](https://docs.julialang.org/en/v1/stdlib/Random/#Base.rand) doc for further details.
* `.+=` is the Julia syntax to do an "in-place" vector addition. Concerning performance, this is an important syntax to know, see ["dot call" syntax](https://docs.julialang.org/en/v1/manual/mathematical-operations/#man-dot-operators)
---
**Update** a more efficient approach, is :
```
map!(vi->vi+rand(1:100),v,v)
```
Note: the approach is more efficient as it avoids the creation of the `rand(1:100,length(v))` temporary vector.
---
**Update** an alternative, if you want to **fill** (and not to add) the vector with random integers, is @DNS's one (see comment) :
```
using Random
v = Vector{Int}(undef,30)
rand!(v,1:100)
```
Note:
* `Vector{Int}(undef,30)` is the Julia's way to create a vector of 30 **uninitialized** integers.
* the `rand!()`function **fills** this vector with random integers. Internally it uses a for loop.
.
```
rand!(A::AbstractArray{T}, X) where {T} = rand!(default_rng(), A, X)
# ...
function rand!(rng::AbstractRNG, A::AbstractArray{T}, sp::Sampler) where T
for i in eachindex(A)
@inbounds A[i] = rand(rng, sp)
end
A
end
``` | the idiomatic way of doing this in one line is probably
```

Es handelt sich um keine indirekte Rede wo der Konjunktiv 1 hauptsächlich verwendet wird.
Meines Wissens nach sollte hier Konjunktiv 2 verwendet werden, also:

] | Von der Konsistenz her gesehen hast Du recht und es müsste der Konjunktiv 2 verwendet werden. Da sie tatsächlich getrennt waren, beschreibt der Nebensatz eine irreale Situation, wofür normalerweise der Konjunktiv 2 verwendet wird. Es liegt keine indirekte Rede (oder ähnliches) vor, die den Konjunktiv 1 verlangen würde.
Einige Präskriptivisten raten deshalb von dieser Verwendung ab, z. B. [Belles Lettres](https://www.belleslettres.eu/content/konjunktiv/konjunktiv.php#vergleich):
>
> Der Konjunktiv 1 hat in Vergleichssätzen allerdings nichts verloren. Die Wortkombinationen *als sei, als habe* usw. sind also immer falsch. Richtig sind *als wäre* und *als hätte*.
>
>
>
**Aber:** Es ist tatsächlich sehr üblich, dass in solchen irrealen Vergleichssätzen der Konjunktiv 1 verwendet wird. So beobachtet zum Beispiel [der Duden](https://www.duden.de/sprachwissen/sprachratgeber/Nebensatze-mit-als-ob-als-wenn-wie-wenn):
>
> In irrealen Vergleichssätzen mit *als ob, als wenn* und *wie wenn* wird sowohl der Konjunktiv I als auch der Konjunktiv II verwendet:

>
> >
> > Du tust ja geradezu, als ob du zu gar nichts zu gebrauchen wär[e]st/sei[e]st.

> Der Konjunktiv II *([...] zu gebrauchen wärest)* ist aber üblicher. Das gilt auch für irreale Vergleichssätze mit *als* bei folgender Verbform:
>
>
>
> >
> > Sie lächelte, als hätte/habe sie niemals lügen müssen.
> >

> >
>

>
Warum der Duden hier einen vagen Unterschied zwischen *als* und *als ob* macht, ist mir unklar. Mir ist kein Unterschied in der Verwendung bewusst.
Von diesem deskriptiven Standpunkt ist die Verwendung des Konjunktiv 1 in Vergleichssätzen legitim:
Es ist korrekt, weil es so verwendet wird (und zwar auch in der Hochsprache).
Ob diese Verwendung aus Schludrigkeit, Hyperkorrektur, dem Lateinischen, oder etwas anderem erwachsen ist, kann ich nicht sagen.
Die Antwort auf Deine Frage ist also:
Der Konjunktiv 1 wird hier verwendet, da es sich um einen irrealen Vergleichssatz handelt und diese einen Spezialfall darstellen. | Nach meinem persönlichen Sprachempfinden ist der Satz schlicht falsch, und er müsste korrekt lauten: "... als **wären** sie ..." |

This is for testng. This would run all the methods/classes/tests in parallel rather than sequentially.

*What* computer can tell whether a pattern will repeat? This means not knowing the basics of mathematics. The second statement is simply ridiculous. Please, be careful in believing to what can be found on the net.
A definition of an irrational number that uses base ten expansion would be ridiculous as well and indeed nobody seriously interested in mathematics would accept it.
A number is rational if some integer multiple of it is integer. It is irrational otherwise. The fact that $\pi$ is irrational has been established by Joahann Heinrich Lambert in 1761, more than 250 years ago. Can you believe that in 250 years nobody would have caught a flaw in the proof of such an important statement?
About a century later, Lindemann proved the fact that $\pi$ not only is irrational but also transcendental. The proof by Lindemann closed, with a negative answer, a 22 century old problem, that is, squaring the circle with ruler and compass. Can you believe that in more than 100 years nobody would have caught a flaw in Lindemann's proof or in the one of a more general theorem by Weierstraß?
Of course, this might be a conspiration involving all mathematicians, who don't want that the rationality of $\pi$ is known by the general public, because the NSA folks base on it their algorithms for decoding instantaneously all encrypted communications. |

] | There are four factors to determining Fair Use of copyrighted material that must be weighed in the balance:
* Purpose and character of use...better if not for profit; better if transforming in some way
* The nature of the work...factual is better, creative works less so
* The amount and substance of the work...less is better; uses that don't get at "the heart of the work" are better. There are no rules about percentages, etc, despite myths to the contrary.
* The effect of the use on market value...if it doesn't take away from real or potential profit, better
Depending on the nature of the book you are writing, you are probably quite safe using screenshots. You are likely writing something that will stimulate sales and that isn't going to reveal workings of the game that are protected.
Your publisher should have experience with this and probably has a policy for when they ask permission. Unfortunately, many people and organizations don't understand Fair Use and err too far on the side of caution, ceding rights they don't actually have to.

If you were for example to make a story book and just use diablo screenshots as illustrations, that would (probably) not be considered fair use even if it is transformative. Neither would it be if you would just publish an outright art book by using the game assets as they are.
If you were making a book about the history of gaming in general, you do not need permissions to use screenshots. For this there is plenty of precedent and it is generally accepted practice, much the same that if you're making a documentary about 80's action movies you don't need permission to show the terminator 2 poster in context in the documentary.
However, it would be better for you if you took the screenshots yourself as that can put in another entity into the copyright chain. In other words you can't just copy the screenshots from a book containing all the nintendo games ever published and put them in your book about all the nintendo and sega games published.
Even including long stretches of video from a game even in a highly critical piece just badmouthing the game for 15 minutes is fair use(jim sterling vs. digital homicide, although that lawsuit wasn't just about the video I think they tried to claim copyright over it as well along the way). |

Depending on the nature of the book you are writing, you are probably quite safe using screenshots. You are likely writing something that will stimulate sales and that isn't going to reveal workings of the game that are protected.
Your publisher should have experience with this and probably has a policy for when they ask permission. Unfortunately, many people and organizations don't understand Fair Use and err too far on the side of caution, ceding rights they don't actually have to.
I teach about Fair Use regularly; you can find more information here: <http://iteachu.uaf.edu/develop-courses/constructing-a-course/copyright/> | The copyright information included with the game itself should tell you the answer to this. They will set out the parameters of what you can and can't do.
My hunch would be that a specific screenshot of a game in action, created by yourself, would be considered 'an original creative work' and would therefore not be restricted by the game publishers copyright rules.
However, you would really need to consult a lawyer specialising in copyright to know what you can and cannot do legally. |

If you were for example to make a story book and just use diablo screenshots as illustrations, that would (probably) not be considered fair use even if it is transformative. Neither would it be if you would just publish an outright art book by using the game assets as they are.
If you were making a book about the history of gaming in general, you do not need permissions to use screenshots. For this there is plenty of precedent and it is generally accepted practice, much the same that if you're making a documentary about 80's action movies you don't need permission to show the terminator 2 poster in context in the documentary.
However, it would be better for you if you took the screenshots yourself as that can put in another entity into the copyright chain. In other words you can't just copy the screenshots from a book containing all the nintendo games ever published and put them in your book about all the nintendo and sega games published.
Even including long stretches of video from a game even in a highly critical piece just badmouthing the game for 15 minutes is fair use(jim sterling vs. digital homicide, although that lawsuit wasn't just about the video I think they tried to claim copyright over it as well along the way). |

1,746,676 | I am creating a classifieds website.
Im storing all ads in mysql database, in different tables.
Is it possible to find these ads somehow, from googles search engine?
Is it possible to create meta information about each ad so that google finds them?

I have thought about auto-generating a html-page for each ad inserted, but 500thousand auto-generated html pages doesn't really sound that good of a solution!

] | Google doesn't find database records. Google finds web pages. If you want your classifieds to be found then they'll need to be on a Web page of some kind. You can help this process by giving Google a site map/index of all your classifieds.
I suggest you take a look at [Google Basics](http://www.google.com/support/webmasters/bin/answer.py?answer=70897&hl=en) and [Creating and submitting SitemapsPrint](http://www.google.com/support/webmasters/bin/answer.py?answer=156184&hl=en). Basically the idea is to spoon feed Google every URL you want Google to find. So if your reference your classifieds this way:
```
http://www.mysite.com/classified?id=1234
```
then you create a list of every URL required to find every classified and yes this might be hundreds of thousands or even millions.
The above assumes a single classified per page. You can of course put 5, 10, 50 or 100 on a single page and then create a smaller set of URLs for Google to crawl.
Whatever you do however remember this: your sitemap should reflect how your site is used. Every URL Google finds (or you give it) will appear in the index. So don't give Google a URL that a user couldn't reach by using the site normally or that you don't want a user to use.
So while 50 classifieds per page might mean less requests from Google, if that's not how you want users to use your site (or a view you want to provide) then you'll have to do it some other way.
Just remember: Google indexes *Web pages* not *data*. | How would you normally access these classifieds? You're not just keeping them locked up in the database, are you?
Google sees your website like any other visitor would see your website. If you have a normal database-driven site, there's some unique URL for each classified where it it displayed. If there's a link to it somewhere, Google will find it. |

Google sees your website like any other visitor would see your website. If you have a normal database-driven site, there's some unique URL for each classified where it it displayed. If there's a link to it somewhere, Google will find it. | First Create a PHP file that pulls the index plus human readable reference for all records.
That is your main page broken out into categories (like in the case of Craigslist.com - by Country and State).
Then each category link feeds back to the php script the selected value regardless of level(s) finally reaching the ad itself.
So, If a category is selected which contains more categories (like states contain cities) Then display the next list of categories. Else display the list of ads for that city.
This will give Google.com a way to index a site (aka mysql db) dynamically with out creating static content for the millions (billions or trillions) of records involved.
This is Just an idea of how to get Google.com to index a database. |

So, If a category is selected which contains more categories (like states contain cities) Then display the next list of categories. Else display the list of ads for that city.

Im storing all ads in mysql database, in different tables.
Is it possible to find these ads somehow, from googles search engine?
Is it possible to create meta information about each ad so that google finds them?
How does major companies do this?
I have thought about auto-generating a html-page for each ad inserted, but 500thousand auto-generated html pages doesn't really sound that good of a solution!
Any thoughts and idéas?
**UPDATE**:
Here is my basic website so far:
(ALL PHP BASED)
I have a search engine which searches database for records.
After finding and displaying search results, you can click on a result ('ad') and then PHP fetches info from the database and displays it, simple!
In the 'put ad' section of my site, you can put your own ad into a mysql database.
I need to know how I should make google find ads in my website also, as I dont think google-crawler can search my database just because users can.

] | Google doesn't find database records. Google finds web pages. If you want your classifieds to be found then they'll need to be on a Web page of some kind. You can help this process by giving Google a site map/index of all your classifieds.
I suggest you take a look at [Google Basics](http://www.google.com/support/webmasters/bin/answer.py?answer=70897&hl=en) and [Creating and submitting SitemapsPrint](http://www.google.com/support/webmasters/bin/answer.py?answer=156184&hl=en). Basically the idea is to spoon feed Google every URL you want Google to find. So if your reference your classifieds this way:
```
http://www.mysite.com/classified?id=1234
```
then you create a list of every URL required to find every classified and yes this might be hundreds of thousands or even millions.
The above assumes a single classified per page. You can of course put 5, 10, 50 or 100 on a single page and then create a smaller set of URLs for Google to crawl.
Whatever you do however remember this: your sitemap should reflect how your site is used. Every URL Google finds (or you give it) will appear in the index. So don't give Google a URL that a user couldn't reach by using the site normally or that you don't want a user to use.
So while 50 classifieds per page might mean less requests from Google, if that's not how you want users to use your site (or a view you want to provide) then you'll have to do it some other way.
Just remember: Google indexes *Web pages* not *data*. | Google can find you no matter *where* you try to hide. Even if you can somehow fit yourself into a mysql table. Because they're Google. :-D
Seriously, though, they use a bot to periodically spider your site so you mostly just need to make the data in your database available as web pages on your site, and make your site bot-friendly (use an appropriate robots.txt file, provide a search engine-friendly site map, etc.) You need to make sure they can *find* your site, so make sure it's linked to by other sites -- preferably sites with lots of traffic.
If your site only displays specific results in response to search terms you'll have a harder time. You may want to make full lists of the records available for people without search terms (paged appropriately if you have lots of data). |

213,778 | I want to perform a statistical test: Wilcoxon Signed Rank Test to test if there is a significant difference between them, but I don't know if the two samples are dependent or not?
Context: I have a dataset that contains a set of elements, I want to predict the dependent variable, I use two models A and B to perform the prediction using LOOCV. So, I have two samples based on the absolute errors (sample A: contains the absolute errors based on prediction of Model A, Sample B: contains the absolute erroers based on prediction of Model B).
My Question: is the sample A and B are dependent or independent?

] | The answer is *dependent*. Or, to be a bit more precise: paired.
The thing to keep in mind here is that you only have one sample, and have two measurements for each observations in that sample.
If, instead, you had two distinct samples (e.g., one representing the first 100 cases in your data set and the other the second 100 cases), and were comparing the predictive accuracy between these two samples, you would then have two independent samples. | Two or more samples are said to be dependent, in short, if one sample is dependent or is influenced by another. Suppose, one wants to study earning difference between men and women. So s/he randomly selects 100 men and 100 women, and records interested variable values. In this case, the samples are independent because a man's earning value cannot be related to that of a woman. Let's again say, one collects data of 100 couples. Here, the samples are dependent in that couples tend to have similarities in aspects like *level of education*, *ambition*, *ethnicity*, etc. If one finds factors that are likely to affect samples, then they should be treated as dependent. |

 | I found that the only MAIN step (instead of steps 1-5 in the accepted answer of Sebastian Zartner) is to FIRST enable Firebug's HTML tab's "Break On Mutate" button. It is the most left-top button in that tab.

64,288,547 | Currently doing a school mini-project where we have to make a program to extract the domain name from a few given URL's, and put those which end in .uk (ie are websites from the united kingdom) in a list.
A couple of specifications:
* We cannot import any modules or anything.
* We can ignore urls that don't start with either "http://" or "https://"
I was originally just going to do:
```
uksites = []
file = open('urlfile.txt','r')
urllist = file.read().splitlines()
for url in urllist:
if "http://" in url:
domainstart = url.find("http://") + len("http://")
elif "https://" in url:
domainstart = url.find("https://") + len("https://")
domainend = url.find("/", domainstart)
if domainend >= 0:
domain = url[domainstart:domainend]
else:
domain = url[domainstart:]
if domain[-3:] = ".uk":
uksites.append(url)
```
But then our professor warned us that not all domain names will be ended with a "/" (for example, one of the given ones in the test file we were supplied ends with ":")
Is this the only other valid character that can signify the end of a domain name? or are there even more?
If so how could I approach this?
The test file is pretty short, it contains a few "links" (some aren't real sites apparently):

An url contains a few characters which cannot appear randomly e.g. the dot "."
The last dot allows therefore marks the end of the url + the country code.
The easiest solution could be to split the urls at the last dot with .rsplit(".", 1) and then take the first 2 letters after the split and re-attach them to the first part of the split. I chose a different approach and checked the second part after the split for alphanumeric characters, because after the country code there is always a special character (non-alphanumeric) so this allows for an additional split of the second part.

] | How dare you! How dare you question the most secure mobile platform available to mankind! My attempt at humor there.. now to a serious answer before the mods attack. Blackberry has some whitepapers regarding security here: <http://us.blackberry.com/ataglance/security/>
I would argue the network is not RIM's strongest asset. Corporate and government adoption of the product due to the level of control they have over the devices is RIM's strongest asset. MDM is a hot topic now, but people seem forget that RIM has been doing it for 14 years.
Unfortunately for RIM the pendelum has swung away from corporate control towards the "bring your own device" philosophy, and with good reason. Android and IOS offers a better user experience. | Blackberry Architecture is designed in such a way that the entire communication (data and not voice channel) is managed by the blackberry servers ecosystem in highly secured manner. The telco data channel acts as a carrier and transport medium of data packets to and fro between the mobile device and the blackberry servers like BIS and BES.
For establishing the ecosystem the telco is needed to host blackberry servers and applications in its network infrastructure. Hence to use the blackberry service it is important that the telco have the blackberry infrastructure setup.
In my knowledge there are 2 unique things about blackberry compared to other devices in a telco network ecosystem:
1. Blackberry devices have a secured element in them. The secure element can be compared to a secure smart card (Not the SIM card provided by telco). Blackberry initializes it with some keys and certificates in the manufacturing time. The mapping is referred as the device PIN.
2. Unlike other devices in network, blackberry devices are allowed to listen in a socket port which typically is not allowed by telco in other devices. This is from where the true sense of push mail or push messaging originates. In sense blackberry devices have true push support while other devices actually perform pull and make it look like push. This is one more reason why blackberry device have high battery life even after performing heavy data transmission operations.
Now the security; as discussed in one of the post many documents are public. AFAIK the session key which is derived in between blackberry servers and mobiles is generated in such way that key is not recoverable even on the server. For this reason, blackberry has been pushed by many nations to host some servers and do some modifications so that the intelligence agencies can trace data transmitted and received by the devices.
Blackberry devices from long have the processing capability of performing crypto operations like AES, RSA, ECC and many more. It supports full fledged PKI operations like signing and validations. In-fact BB was one of the first to have ECC support and own the Certicom Infra. |

I think this was initially what brought blackberry proliferation to the insane levels it reached in the early 2000's in the corporate world. | Blackberry Architecture is designed in such a way that the entire communication (data and not voice channel) is managed by the blackberry servers ecosystem in highly secured manner. The telco data channel acts as a carrier and transport medium of data packets to and fro between the mobile device and the blackberry servers like BIS and BES.
For establishing the ecosystem the telco is needed to host blackberry servers and applications in its network infrastructure. Hence to use the blackberry service it is important that the telco have the blackberry infrastructure setup.
In my knowledge there are 2 unique things about blackberry compared to other devices in a telco network ecosystem:
1. Blackberry devices have a secured element in them. The secure element can be compared to a secure smart card (Not the SIM card provided by telco). Blackberry initializes it with some keys and certificates in the manufacturing time. The mapping is referred as the device PIN.
2. Unlike other devices in network, blackberry devices are allowed to listen in a socket port which typically is not allowed by telco in other devices. This is from where the true sense of push mail or push messaging originates. In sense blackberry devices have true push support while other devices actually perform pull and make it look like push. This is one more reason why blackberry device have high battery life even after performing heavy data transmission operations.
Now the security; as discussed in one of the post many documents are public. AFAIK the session key which is derived in between blackberry servers and mobiles is generated in such way that key is not recoverable even on the server. For this reason, blackberry has been pushed by many nations to host some servers and do some modifications so that the intelligence agencies can trace data transmitted and received by the devices.
Blackberry devices from long have the processing capability of performing crypto operations like AES, RSA, ECC and many more. It supports full fledged PKI operations like signing and validations. In-fact BB was one of the first to have ECC support and own the Certicom Infra. |
15,053,715 | I'm making a management program with C# & SQL Server 2008. I want to search records using Blood Group, District & Club Name wise all at a time. This is what is making prob:
```
SqlDataAdapter sda = new SqlDataAdapter("SELECT * FROM Table2
WHERE @Blood_Group =" + tsblood.Text + "AND @District =" + tsdist.Text +
"AND Club_Name =" + tscname.Text, Mycon1);
```

] | The correct syntax is to use parametrized queries and absolutely never use string concatenations when building a SQL query:
```
string query = "SELECT * FROM Table2 WHERE BloodGroup = @BloodGroup AND District = @District AND Club_Name = @ClubName";
using (SqlDataAdapter sda = new SqlDataAdapter(query, Mycon1))
{
sda.SelectCommand.Parameters.AddWithValue("@BloodGroup", tsblood.Text);
sda.SelectCommand.Parameters.AddWithValue("@District", tsdist.Text);
sda.SelectCommand.Parameters.AddWithValue("@ClubName", tscname.Text);
...
}
```
This way your parameters will be properly encoded and your code not vulnerable to SQL injection attacks. Checkout [`bobby tables`](http://bobby-tables.com/).
Also notice how I have wrapped IDisposable resources such as a SqlDataAdapter into a using statement to ensure that it is properly disposed even in case of an exception and that your program will not be leaking unmanaged handles. | You forgot an `AND` (and possible an `@` in front of `Club_Name`?):
```
String CRLF = "\r\n";
String sql = String.Format(
"SELECT * FROM Table2" + CRLF+
"WHERE @Blood_Group = {0}" + CRLF+
"AND @District = {1} " + CRLF+
"AND Club_Name = {2}",
SqlUtils.QuotedStr(tsblood.Text),
SqlUtils.QuotedStr(tsdist.Text),
SqlUtils.QuotedStr(tscname.Text));
SqlDataAdapter sda = new SqlDataAdapter(sql, Mycon1);

34,995 | I planted red and new potatoes in early May. They were planted 6-8 inches deep. The potatoes were sprouted potatoes from our local hardware store.

We watered the potatoes using a drip system (2 GPH) that was set to 15 minutes once per week. However, the summer here has been very hot and whenever the plants looked wilted, we added an additional watering cycle. | 2017/08/13 | [

] | Judging by the state of the plants when you dug them up, and what the soil surface looks like there are no nutrients whatever in it.
The potatoes *tried* to grow, using the material stored in the tuber, but that's as much as they managed to do. The leaves never developed properly, nor did the roots. They would have grown just as "well" if you had just put them on a concrete driveway and ignored them.
"Purchased humus" doesn't necessarily contain any nutrients. If you really want to grow potatoes in this soil, I would dig the area now to break it up, then spread about a 6 inch depth of horse manure on the surface and leave it for 3 months to let the micro-organisms to break it down and release the nutrients, then dig it in. That might give you better results next year! | >

This might very well be the reason. Potatoes tend to stop the production of tubers once the soil reaches a certain temperature. Gardeners that plant their potatoes in dark plastic bags and unwittingly put the bags into a sunny spot often have the same problem.
Next year, plant your potatoes as early as possible to get a long growing phase before the summer heat sets in. |

The tubers actually grow along the stems of the plants, so if you don't cover them up, you may grow larger plants next year, but they still don't produce a crop of any size.

34,640,668 | I'm working on a plugin for Revit. Revit permits only dll type addins and I chose c# and wpf for gui. I couldn't initialize wpf natively so I needed to contain it in a system.windows.window as content.
Now if I close that window with upper right X program continues (looping processing etc.) it doesn't get terminated. Window.close() again just closes the window not the application it self.
How should I exit my app and not keep it lurking in the shadows?
```
[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class FDNMain : IExternalCommand
{
public Result Execute(ExternalCommandData CommandData, ref string message, ElementSet elements)
{
FDNControl wpfControl = new FDNControl();
return Result.Succeeded;
}
}
```
Above is the Revit external command class which cannot initialize (show up) the wpfControl. So I need to wrap the wpfcontrol with a System.Windows.Window as below:
```
Window hostWindow = new Window();
hostWindow.Content = wpfControl;
hostWindow.Show();

] | Unfortunately I don't know how to do this without any existing form. But I'm sure you have some kind of main form you can access. Or you can obtain a `Form` using
```
var invokingForm = Application.OpenForms[0];
```
So you can change the code of your method like this:
```
static void OnNewMessage(object sender, S22.Xmpp.Im.MessageEventArgs e)
{
var invokingForm = Application.OpenForms[0]; // or whatever Form you can access
if (invokingForm.InvokeRequired)
{
invokingForm.BeginInvoke(new EventHandler<S22.Xmpp.Im.MessageEventArgs>(OnNewMessage), sender, e);
return; // important!!!
}
// the rest of your code goes here, now running
// on the same ui thread as invokingForm
if(CheckIfFormIsOpen(e.Jid.ToString(), e.Message.ToString()) == true)
{
}
else
{
newMessageFrm tempMsg = new newMessageFrm(e.Jid.ToString());
tempMsg._msgText = e.Jid.ToString() + ": " + e.Message.ToString();
tempMsg.frmId = e.Jid.ToString();
tempMsg.Show();
}
}
```
Note that I assumend that `S22.Xmpp.Im.MessageEventArgs` is inherited from `System.EventArgs`. | In WinForms there is still a requirement that the UI objects need to be on a thread with a message pump. This is usually the main application thread, also called the UI thread.
In Winforms checking to see if you are on the right thread to access a UI object is done with `Control.InvokeRequired`. If this returns true, it means you are not on the proper thread, and need to use an Invoke operation.
Since you know you are one a different thread, you don't need to check, you can just Invoke.
```
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ThreadPool.QueueUserWorkItem(BadBackgroundLaunch);
ThreadPool.QueueUserWorkItem(GoodBackgroundLaunch);
}
private void GoodBackgroundLaunch(object state)
{
this.Invoke((Action) (() =>
{
var form2 = new SecondForm();
form2.Text = "Good One";
form2.Show();
}));
}
private void BadBackgroundLaunch(object state)
{
var form2 = new SecondForm();
form2.Text = "Bad one";
form2.Show();
}
}

35,253,840 | I am building an app which uploads files to the server via ajax.
The problem is that users most likely sometimes won't have the internet connection and client would like to have the ajax call scheduled to time when user have the connection back. This is possible that user will schedule the file upload when he's offline and close the app. Is it possible to do ajax call when the application is closed (not in background)?
When app is in the background, we can use background-fetch but I have never faced a problem to do something when app is closed. | 2016/02/07 | [

] | The short answer is no, your app can't run code after being terminated.
You can run code in your `AppDelegate`'s `applicationWillTerminate`, but that method is mainly intended for saving user data and other similar tasks.
See [this answer](https://stackoverflow.com/a/32225247/5389870) also. | Yes you can do stuff in the background. You are limited to several different background modes of execution. Server communication is one of the modes that is allowed (background fetch). Make sure you set the properties correctly in Xcode per the guidelines (i.e. don't say you are a audio app when you are doing data transfer). See the details here:
<https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html>
I found your question because it has the Cordova tag associated with it. If you are using Cordova you can use this plugin here to manage things in the background:
<https://github.com/katzer/cordova-plugin-background-mode>
Edit: If the user is FORCE closing / terminating the app then there is nothing you can do. If they are just exiting the app to the home screen and use other apps, then you can run in the background.
The other option you can do is schedule a local notification to upload the file. If you app successfully uploads the file because it is open / has a connection / did it in the background, then you cancel the local notification.
If the local notification isn't cancelled it will remind the user the file is not uploaded and when they open the notification your app will start back where it left off. |
