What's the difference between actual arguments, format arguments, dummy arguments and actual and formal parameters? : <p>I think some mentioned above are just synonyms but which ones? Also correct me if I'm wrong: In a function lets say the main function, the data between parenthesis is parameters/arguments?</p>

Simple way to replace string in javscript with wildcards : Is there a simple way to replace something in a string in javascript with a wildcard but also use the wildcard in the resulting string:
So for example i have the String:
loop(10)
{
// do something
}
an i want to replace the "loop" with a real for loop like this
for(i=0; i<10; i++)
{
// do something
}
but to do this i with a simple .replace i would need a wildcard. Obviously there is a solution to this problem but it seems very costly to me.

Forwarding from a futures::Stream to a futures::Sink : <p>I am currently trying to wrap my head around the tokio & futures primitives and ecosystem.</p>
<p>I started doing some work from the <a href="https://github.com/swindon-rs/tk-http/blob/abfdb50a00ab90b4f01b23ff8dbefe6e83331d9c/examples/websockets.rs" rel="noreferrer">tk-http websockets example</a>, and wanted to do more processing on the received data rather than echoing it back. A first step seemed to be to replace the .forward() call with some kind of loop.</p>
<p>It seemed to me that <code>stream.forward(sink)</code> is equivalent to <code>stream.fold(sink, |out_, item| { out.send(item).and_then(Sink::flush) })</code>, however doing this (<a href="https://gitlab.com/remram44/rs-web/commit/b1edd5a68ddb676b6a912576bdf08600cbeab96e" rel="noreferrer">commit</a>) the stream is not polled at all. However the same change from the Tokio example works fine (<a href="https://gitlab.com/remram44/rs-web/commit/5345a3e7f5f4e4ec81791d5e7e0474154329bd0e" rel="noreferrer">example</a>).</p>
<p>Furthermore, it seems that outputting something on the sink first makes the forwarding work fine (<a href="https://gitlab.com/remram44/rs-web/commit/d690039fde5d4d6ab35f0f0a13be3ef46c84807b" rel="noreferrer">commit</a>), so maybe the sink doesn't get registered with the event loop for some reason until a send happen? Did I miss something? Is it possible it is a bug in tk-http?</p>

Why .RData when .R is sufficient : <p>Say, if we can save and load an exact same data from <code>.R</code> files, then why came the need for <code>.RData</code>.

So, I stumbled upon few queries:</p>
<ul>
<li>Does <code>.RData</code> <strong>saves</strong> <strong>only final result</strong> or complete code just a <code>.R</code> scripts?</li>
<li>What is their exact relevance? Which one to prefer over other and when?</li>

How to take a sample of a data set in R : <p>So I have this dataset with 18 variables and about 10,000,000 observations. The set is way to large for my computer to handle so I need to take a smaller sample of the data to analyze it. However, I don't want just a random sample. One of my variables "tip_level" is a factor with two levels, "high" and "low". Is there a way to take a sample of 100,000 observations where 50,000 are "high" and 50,000 are "low" of the variable?</p>

<p>Does TensorFlow make use of all the devices (GPUs and CPUs) available

<p>TensorFlow supports multiple GPUs and CPUs. See the how-to

TensorFlow assigns operations to devices, and the CIFAR-10 tutorial
for an example model that uses multiple GPUs.</p>
<p>Note that TensorFlow only uses GPU devices with a compute capability

<pre><code>public class Utilities {
private static Utilities utils;
public static Utilities getInstance() {
if (utils == null)
utils = new Utilities();
return utils;
}
public static void someMethod() {
}

I have used vs2017 to open a vs 2010 MFC project.
It could be opened well in the first time.
however, afterwards, it reminds me to do some update. After that, the file can not be load in resourse view.
[enter image description here][1]
How to reconfig vs to show the resourse view?

How to run a migration in production : <p>I am new to migrations and I can't find out what to do to get my changes onto the LiveDB.</p>
<p>So on dev when I add to my model I do</p>
<pre><code>PM> add-migration <name>
PM> update-database
</code></pre>
<p>But what do I do on live? I was HOPING that I could just publish\deploy to live and the migration would run and update the schema, but I guess not :)</p>
<p>The Live SQL server is off in its own world I have no access to it from my dev box to just change the connectionstring and doing an update-database again.</p>
<p>What do you guys do, where's the docs?</p>
<p>Thanks,
Steve</p>

Change return to be next/done key in Xamarin Forms Shared Project : <p>Is it possible to change the text in the 'return' key on the keyboard to be either 'next' or 'done'? I have a login form with username and password. I want the return key to say 'next' when on the username field and then 'done' when on the password field but haven't seen anyway of doing this.
This is for a shared project, android and iOS. </p>

How would I animate the width of a button based on percentage, and the same for it's backgroundColor? : <p>I have some <code><AnimatedButton /></code></p>
<p>I want to animate it to go from 100% width to 40% width depending on a prop that is a boolean called <code>isFullWidth</code>.</p>
<p>I have:</p>
<pre><code>class AnimatedButton extends Component {
constructor(props) {
super(props);
this.state = { width: new Animated.Value(100) };
}
toggleWidth() {
const endWidth = this.props.isFullWidth ? 40 : 100;
Animated.timing(this.state.width, {
toValue: endWidth,
duration: 200,
easing: Easing.linear,
}).start();
}
render() {
<TouchableOpacity
style={{ width: `${this.state.width}%` }}
onPress={this.props.onPress}
>
// more stuff
</TouchableOpacity>
}
}
</code></pre>
<p>The problem is that it just jumps into the appropriate percentage without animating. I tried setting the width to just <code>this.state.animatedValue</code> and rather than use percentage, just use pixels, e.g. 150 to 400 and back, and it works fine as expected.</p>
<p>Same question applies for going from say <code>rgba(220, 100, 50, 0.8)</code> to <code>rgba(30, 70, 30, 1.0)</code> and back?</p>

Using element + element with after pseudo element : Trying to achieve a simple effect in a chat app, where if a user messages, after his username should always appear a `:` but if a bot messages, his message will have a class of .bot and i would like to override that `user:after` to have different after content
.user:after {
content: ": ";
}
.user:after + .bot {
content: "=> ";
}
Is this possible at all? Or should i pursue a different approach.

Swift: Dismiss view1 then show a view2 : I want to dismiss a loader view then present an `UIDocumentInteractionController`. I found an objective-c solution but I want the Swift 3 one.
This is the objective-c code taken from this [answer]:
// Does not break
[viewController1 dismissViewControllerAnimated:YES completion:^{
[self presentViewController:viewController2 animated:YES completion:NULL];
}];
I translated like this in Swift 3:
self.dismiss(animated: false, completion:{
self.docController = UIDocumentInteractionController(url: destinationUrl!)
self.docController!.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)
})
Still now it works but I want to be sure that the `completion:^{` in objective-c means `completion:{` in Swift 3.

React Why Unmount Component Slow : <p>I have a component that wraps a bunch of ReactList components.
ReactList component is a component that does infinite scrolling ie only load what's on viewport. It has couple of modes: simple and uniform. I'm using simple which just loads and loads as you scroll down (making the scrollable page longer). Uniform loads and removes the above section that is now out of viewport. I tried using uniform mode, and if it worked I wouldn't even need to ask what I'm about to, but it's super buggy and defeats the purpose. Simple on the other hand is super fast scrolling and loading is equally fast.</p>
<p>I broken down my list into few groups where user can click and it will load that ReactList component. If the scrollable page is short, ie, user hasn't scrolled all the way down, changing between the group of lists is fast enough. ~2s. However, if the page is scrolled all the way down, and trying to change list takes ~6s.</p>
<p>I noticed that the page is fully loaded too, ie nothing more to load. So okay, I think maybe if I change the key for the wrapper parent component and just remount the component, it should be fast right? Nope. The component that reloads is short, only one viewport length, but it takes around ~5s.</p>
<p>I noticed changing out of the fully loaded list component page to just regular single line text "Hello world" component still took around the same amount! ~5s. What's up with that?</p>
<p><strong>QUESTION: Why is unmounting a long page with many small components in a list take so long to just unmount?</strong></p>
<p>Sorry I realize this is long and full of text but I thought I should explain my situation.</p>

why can't android urlEncode like everyone else? : I am having to do stupid s**t like this to get urlEncoding to work like other libraries (iOS, Javascript..) because `java.net.URLEncoder` is buggy or not written to standard encoding:
URLEncoder.encode(normalizeString(str), StandardCharsets.UTF_8.displayName())
.replace("+", "%20")
.replace("%40", "@")
.replace("*", "%2A");
`+` and `*` are not percent encoded while `@` is. and...now it's encoding forward slash `/`. wtf! is there a good explanation for this? Am I using the wrong Charset?

What regex syntax is this, and how do I make it run on .NET? : <p>I'm looking for a suitable regex for hyperlinks. </p>
<p>I found a link to this website: <a href="https://mathiasbynens.be/demo/url-regex" rel="nofollow">https://mathiasbynens.be/demo/url-regex</a>, which has several choices. (There are too many to list here.)</p>
<p>However, these do not seem to be compatible with .NET's Regex syntax. I tried using the "cowboy" pattern vs several hyperlinks, e.g. <a href="http://www.cnn.com" rel="nofollow">http://www.cnn.com</a>, but no match results. </p>
<p>What syntax are these, and how do I get these to work with .NET? If these require manual tweaking, then just showing how to get the "cowboy" pattern to run will suffice.</p>

node http-server not serving updated html files : <p>I am building out a front-end web app with angular (mostly ui-router) and doing local development by serving the html files through node <a href="https://github.com/indexzero/http-server" rel="noreferrer">http-server</a>. I have noticed that http-server isn't serving my static html files when I make updates, which is challenging to my local development.</p>
<p>I have http-server installed globally with <code>npm install http-server -g</code> and start it up by going to the root project folder and running <code>http-server</code>. It defaults to localhost:8080- the two ways that seem to work is changing the port number after each update or going through chrome incognito mode.</p>
<p>Is there a way to use http-server normally without having to change the port or using incognito mode?</p>
<p>If it is relevant, I am using MBP v. 10.11.3</p>
<p>Thank you!</p>

How to limit for 10 results the array.filter? : <p>I have big array, I want to make an autocomplete search, but I want to display only 10 results, so stop iterating through the array by the time there were found 10 results. I have made this:</p>
<pre><code>let items = array.filter(r => r.indexOf(term)!=-1);
console.log(items.length) // lots of items, need to be limited to 10
</code></pre>
<p>It works but I don't know how to stop the <code>array.filter</code> by the time it reaches the desired limit.</p>

nth-child returning source, not the expected target(s) : I'm trying to sharpen my jQuery skills by learning to use `nth-child` selector but with little luck. I'm sure I'm just doing something slightly wrong, and I will have a follow up question to this again regarding nth-child, so any help is appreciated.
I would have thought my code below would have select "Saab" and "Audi" in the pulldown menu, but what it does is return the "source" `select` element, `select#carsmenu`. What am I doing wrong?
<script>
$(document).ready(function() {
console.log($('#carsmenu:nth-child(odd)').prop('selected', true));
});
</script>
<select multiple id="carsmenu">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>

<p>The AWS EC2 instances in question do not exist indeed, but TF errors out when trying to delete them (presumably because they don't exist) and still keeps them in the state. </p>
<p>I tried using the <code>terraform state</code> command in an attempt to remove the <code>deposed</code> resources, but it only allows me to delete the whole resource, not just the <code>deposed</code> instance of it... </p>
<p>Am I expected to, simply, manually go in the terraform state file and delete the deposed sections??</p>

Change Carthage Swift version : <p>Is it possible to change Carthage Swift version used to build the frameworks?</p>
<p>I'm trying to migrate my project to swift 3 (on Xcode 8 beta), and the third party libraries are the only thing that stops my project from compiling.
While using specific branches for swift 3, Carthage throws errors about the new Swift syntax.</p>

#add the created instance (self) to people class variable
end
#have a `search` method to locate all people with a matching `last_name`
def self.search(last_name)
#accept a `last_name` parameter
#search the `people` class attribute for instances with the same `last_name`
#return a collection of matching instances
end
#have a `to_s` method to return a formatted string of the person's name

#return a formatted string as `first_name(space)last_name`

Does SQL have a condition like 'IS UNIQUE'? : <p>Wherever I was looking for, I've never heard about that any SQL implementations would have an <code>IS UNIQUE</code> "command". Did I miss something? If I'm right, what is the reason?</p>
<p>In other words, why I can't state in SQL that a certain command, such as <code>INSERT INTO</code> (<em>especially</em> that) can be done only if a value is or is not considered UNIQUE?</p>

golang json doesn't parse fields with tag of embedded structure correctly : <pre><code>package main
import (
"encoding/json"
"fmt"
)
type InnerData struct {
M int64 `josn:"m"`
N int64 `json:"n"`
}
//JSONData is a json data example
type JSONData struct {
Hello string `json:"hello"`
Data InnerData `json:"data"`
}
func main() {
v := JSONData{Hello: "world", Data: InnerData{N: 100000, M: 123456}}
mashaled, err := json.Marshal(&v)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(string(mashaled))
}
</code></pre>
<p>Noted the field M in InnerData has a tag m, so the expected result is :{"hello":"world","data":{"m":123456,"n":100000}}.
While I have </p>
<pre><code>{"hello":"world","data":{"M":123456,"n":100000}}
</code></pre>
<p>Does anyone know how to fix the problem, or where am I wrong?</p>
