This will get the version of the GTK+ libraries for GTK+ 2 and GTK+ 3.

dpkg -l | egrep "libgtk(2.0-0|-3-0)"

As major versions are parallel installable, you may have both on your system, which is my case, so the above command returns this on my Ubuntu Trusty system:

ii  libgtk-3-0:amd64                                      3.10.8-0ubuntu1.6                                   amd64        GTK+ graphical user interface library
ii  libgtk2.0-0:amd64                                     2.24.23-0ubuntu1.4                                  amd64        GTK+ graphical user interface library

This means I have GTK+ 2.24.23 and 3.10.8 installed.

If what you want is the version of the development files, use pkg-config --modversion gtk+-3.0 for example for GTK+ 3. To extend that to the different major versions of GTK+, with some sed magic, this gives:

pkg-config --list-all | sed -ne 's/\(gtk+-[0-9]*.0\).*/\1/p' | xargs pkg-config --modversion

I didn't see an answer that's clean and suitable for production-ready software, so here it goes:

/*
 * Get current error_reporting value,
 * so that we don't lose preferences set in php.ini and .htaccess
 * and accidently reenable message types disabled in those.
 *
 * If you want to disable e.g. E_STRICT on a global level,
 * use php.ini (or .htaccess for folder-level)
 */
$old_error_reporting = error_reporting();

/*
 * Disable E_STRICT on top of current error_reporting.
 *
 * Note: do NOT use ^ for disabling error message types,
 * as ^ will re-ENABLE the message type if it happens to be disabled already!
 */
error_reporting($old_error_reporting & ~E_STRICT);


// code that should not emit E_STRICT messages goes here


/*
 * Optional, depending on if/what code comes after.
 * Restore old settings.
 */
error_reporting($old_error_reporting);

You most certainly have a databases tab in sql developer (all versions I've used in the past have this). Maybe check again? Perhaps, you're looking in the wrong location.

On a mac, the preferences is under "Oracle SQL Developer" (top left) -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

On windows (going from memory so might have to search if this isn't correct) Tools -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

There's more then one way to do this with DateTime which was introduced in PHP 5.2. Unlike using strtotime() this will account for daylight savings time and leap year.

$datetime = new DateTime('2013-01-29');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.3

$datetime = new DateTime('2013-01-29');
$datetime->add(new DateInterval('P1D'));
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.4

echo (new DateTime('2013-01-29'))->add(new DateInterval('P1D'))->format('Y-m-d H:i:s');

// Available in PHP 5.5

$start = new DateTimeImmutable('2013-01-29');
$datetime = $start->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

To produce a list of methods put the name of the method in a list without the usual parenthesis. Remove the name and attach the parenthesis and that calls the method.

    def methodA():
        print("@ MethodA")

    def methodB():
        print("@ methodB")

    a = []
    a.append(methodA)
    a.append(methodB)
    for item in a:
        item()

For finding objects which are meaningfully equal, you need to override equals and hashcode methods for the class. You can find a good tutorial here.

I am not sure if you are trying to create a remote branch from a local branch or vice versa, so I've outlined both scenarios as well as provided information on merging the remote and local branches.

Creating a remote called "github":

git remote add github git://github.com/jdoe/coolapp.git
git fetch github

List all remote branches:

git branch -r
  github/gh-pages
  github/master
  github/next
  github/pu

Create a new local branch (test) from a github's remote branch (pu):

git branch test github/pu
git checkout test

Merge changes from github's remote branch (pu) with local branch (test):

git fetch github
git checkout test
git merge github/pu

Update github's remote branch (pu) from a local branch (test):

git push github test:pu

Creating a new branch on a remote uses the same syntax as updating a remote branch. For example, create new remote branch (beta) on github from local branch (test):

git push github test:beta

Delete remote branch (pu) from github:

git push github :pu

save the file on your disk and then use the following as URL:

file://your_path/your_file.wsdl

I have edited one of the previous post. Now, it is way more simple and it works perfectly.

<input style="position: absolute;left:-9999px;" type="radio" name="emotion" id="sad" />
<label for="sad"><img src="red.gif" style="display: inline-block;cursor: pointer;padding: 3px;" alt="I'm sad" /></label>

<input  style="position: absolute;left:-9999px;" type="radio" name="emotion" id="happy" />
<label for="happy"><img src="blue.gif" style="display: inline-block;cursor: pointer;padding: 3px;" alt="I'm happy" /></label>

str="abcdef"

str.index('c') #=> 2 #String matching approach
str=~/c/ #=> 2 #Regexp approach 
$~ #=> #<MatchData "c">

Hope it helps. :)

I have found a way to resize the buffer size without influencing the window size. It works thanks to a flaw in how batch works but it gets the job done.

mode 648 78 >nul 2>nul

How does it work? There is a syntax error in this command, it should be "mode 648, 78". Because of how batch works, the buffer size will first be resized to 648 and then the window resize will come but it will never finish, because of the syntax error. Voila, buffer size is adjusted and the window size stays the same. This produces an ugly error so to get rid of it just add the ">nul 2>nul" and you're done.

Yet another way:

:'<,'>g/^/norm I//

/^/ is just a dummy pattern to match every line. norm lets you run the normal-mode commands that follow. I// says to enter insert-mode while jumping the cursor to the beginning of the line, then insert the following text (two slashes).

:g is often handy for doing something complex on multiple lines, where you may want to jump between multiple modes, delete or add lines, move the cursor around, run a bunch of macros, etc. And you can tell it to operate only on lines that match a pattern.

There is already a Twig extension that lets you call PHP functions form your Twig templates like:

Hi, I am unique: {{ uniqid() }}.

And {{ floor(7.7) }} is floor of 7.7.

See official extension repository.

Just iterate and add:

for(Map.Entry e : a.entrySet())
  if(!b.containsKey(e.getKey())
    b.put(e.getKey(), e.getValue());

Edit to add:

If you can make changes to a, you can also do:

a.putAll(b)

and a will have exactly what you need. (all the entries in b and all the entries in a that aren't in b)

For completeness, Pandas also has a period_range function for timestamps that are out of bounds:

import pandas as pd

pd.period_range(start='1/1/1626', end='1/08/1627', freq='D')

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

require_once('../web/a.php');

If this is not working for anyone, following is the good Idea to include file anywhere in the project.

require_once dirname(__FILE__)."/../../includes/enter.php";

This code will get the file from 2 directory outside of the current directory.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Try sgrep. It's not clear exactly what you are trying to do, but I surely would not attempt writing an XML parser in bash.

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

You can delete documents from type with following query:

POST /index/type/_delete_by_query
{
    "query" : { 
        "match_all" : {}
    }
}

I tested this query in Kibana and Elastic 5.5.2

String input = "0101";
BigInteger x = new BigInteger ( input , 2 );
String output = x.toString(2);

Another way to do it is to start a local HTTP server on your directory. On Ubuntu and MacOs with Python installed, it's a one-liner.

Go to the directory containing your web files, and :

python -m SimpleHTTPServer

Then connect to http://localhost:8000/index.html with any web browser to test your page.

There is a case I often use. I have a IdUtil class with static methods to work with objects implementing a very simple Identifiable interface:

public interface Identifiable<K> {
    K getId();
}


public abstract class IdUtil {

    public static <T extends Enum<T> & Identifiable<S>, S> T get(Class<T> type, S id) {
        for (T t : type.getEnumConstants()) {
            if (Util.equals(t.getId(), id)) {
                return t;
            }
        }
        return null;
    }

    public static <T extends Enum<T> & Identifiable<S>, S extends Comparable<? super S>> List<T> getLower(T en) {
        List<T> list = new ArrayList<>();
        for (T t : en.getDeclaringClass().getEnumConstants()) {
             if (t.getId().compareTo(en.getId()) < 0) {
                 list.add(t);
            }
        }
        return list;
    }
}

If I create an Identifiable enum:

    public enum MyEnum implements Identifiable<Integer> {

        FIRST(1), SECOND(2);

        private int id;

        private MyEnum(int id) {
            this.id = id;
        }

        public Integer getId() {
            return id;
        }

    }

Then I can get it by its id this way:

MyEnum e = IdUtil.get(MyEnum.class, 1);

I use to throw an exception in the base class.

protected abstractMethod() {
    throw new Error("abstractMethod not implemented");
}

Then you have to implement in the sub-class. The cons is that there is no build error, but run-time. The pros is that you can call this method from the super class, assuming that it will work :)

HTH!

Good point that view is appeared if it's already in window hierarchy stack. thus we can extend our classes for this functionality.

extension UIViewController {
  var isViewAppeared: Bool { viewIfLoaded?.isAppeared == true }
}

extension UIView {
  var isAppeared: Bool { window != nil }
}

There was recently a node module that was made that solves this problem so you don't have to create another component.

https://github.com/Ajackster/react-native-global-props

https://www.npmjs.com/package/react-native-global-props

The documentation states that in your highest order component, import the setCustomText function like so.

import { setCustomText } from 'react-native-global-props';

Then, create the custom styling/props you want for the react-native Text component. In your case, you'd like fontFamily to work on every Text component.

const customTextProps = { 
  style: { 
    fontFamily: yourFont
  }
}

Call the setCustomText function and pass your props/styles into the function.

setCustomText(customTextProps);

And then all react-native Text components will have your declared fontFamily along with any other props/styles you provide.

In my case I had all of the proper references in my project. I found that by building the solution the nuget packages were automatically restored.

I think I've figured it out:

a = [3, 2, 4, 6, 3, 8]
a.delete(3)
#=> 3
a
#=> [2, 4, 6, 8]

following Anton's solution, come up with this ViewHolder which holds/handles/delegates different type of layouts. But not sure if the replacing new layout would work when the recycling view's ViewHolder is not type of the data roll in.

So basically, onCreateViewHolder(ViewGroup parent, int viewType) is only called when new view layout is needed;

getItemViewType(int position) will be called for the viewType;

onBindViewHolder(ViewHolder holder, int position) is always called when recycling the view (new data is brought in and try to display with that ViewHolder).

So when onBindViewHolder is called it needs to put in the right view layout and update the ViewHolder.

Is the way correct to replacing the view layout for that ViewHolder to be brought in, or any problem? Appreciate any comment!

public int getItemViewType(int position) {
    TypedData data = mDataSource.get(position);
    return data.type;
}

public ViewHolder onCreateViewHolder(ViewGroup parent, 
    int viewType) {
    return ViewHolder.makeViewHolder(parent, viewType);
}

public void onBindViewHolder(ViewHolder holder, 
    int position) {
    TypedData data = mDataSource.get(position);
    holder.updateData(data);

Edit: ViewHolder has member mItemViewType to hold the view

Edit: looks like in onBindViewHolder(ViewHolder holder, int position) the ViewHolder passed in has been picked up (or created) by looked at getItemViewType(int position) to make sure it is a match, so may not need to worry there that ViewHolder's type does not match the data[position]'s type. Does anyone knows more how the ViewHolder in the onBindViewHolder() is picked up?

Edit: Looks like The recycle ViewHolder is picked by type, so no warrior there.

Edit: http://wiresareobsolete.com/2014/09/building-a-recyclerview-layoutmanager-part-1/ answers this question.

It gets the recycle ViewHolder like:

holder = getRecycledViewPool().getRecycledView(mAdapter.getItemViewType(offsetPosition));

or create new one if not find recycle ViewHolder of right type.

        final ArrayList<ViewHolder> scrapHeap = mScrap.get(viewType);
        if (scrapHeap != null && !scrapHeap.isEmpty()) {

            final ViewHolder scrap = scrapHeap.get(index);
            scrapHeap.remove(index);
            return scrap;
        }
        return null;

I use a utility that I wrote in C called autotab. It analyzes the first few thousand lines of a file which you load and determines values for the Vim parameters shiftwidth, tabstop and expandtab.

This is compiled using, for instance, gcc -O autotab.c -o autotab. Instructions for integrating with Vim are in the comment header at the top.

Autotab is fairly clever, but can get confused from time to time, in particular by that have been inconsistently maintained using different indentation styles.

If a file evidently uses tabs, or a combination of tabs and spaces, for indentation, Autotab will figure out what tab size is being used by considering factors like alignment of internal elements across successive lines, such as comments.

It works for a variety of programming languages, and is forgiving for "out of band" elements which do not obey indentation increments, such as C preprocessing directives, C statement labels, not to mention the obvious blank lines.

This did the trick for me

public static void main(String[] args) {

    String text = "abcdefghijklmnopqrstuvwxyz";

    for (int i = (text.length() - 1); i >= 0; i--) {
        System.out.print(text.charAt(i));
    }
}

 <?php if (date("H") < "12" && date("H")>"6") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/morning.gif" 
 <?php } elseif (date("H") > "12" && date("H")<"17") { ?>
 src="<?php bloginfo('template_url'); ?>/images/img/noon.gif" 
  <?php } elseif (date("H") > "17" && date("H")<"21") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/evening.gif" 
  <?php } elseif (date("H") > "21" && date("H")<"24") { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/night.gif" 
  <?php }else { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/mid_night.gif" 
  <?php } ?>

You can get column type of DataTable with DataType attribute of datatable column like below:

var type = dt.Columns[0].DataType

dt : DataTable object.

0 : DataTable column index.

Hope It Helps

val() returns the value of the <select> element, i.e. the value attribute of the selected <option> element.

Since you actually want the inner text of the selected <option> element, you should match that element and use text() instead:

var nationality = $("#dancerCountry option:selected").text();

See This question

Your logic in reading

For all built-in Python objects (like strings, lists, dicts, functions, etc.), if x is y, then x==y is also True.

is slightly flawed.

If is applies then == will be True, but it does NOT apply in reverse. == may yield True while is yields False.

Be carefull that the page does not contain any empty component which has "required" attribute as "true" before your selectOneMenu component running.
If you use a component such as

<p:inputText label="Nm:" id="id_name" value="#{ myHelper.name}" required="true"/>

then,

<p:selectOneMenu .....></p:selectOneMenu>

and forget to fill the required component, ajax listener of selectoneMenu cannot be executed.

"Commercial use" in cases like this is actually just a shorthand to indicate that the product is dual-licensed under both an open source and a traditional paid-for commercial license.

Any "true" open source license will not discriminate against commercial use. (See clause 6 of the Open Source Definition.) However, open source licenses like the GPL contain clauses that are incompatible with most companies' approach to commercial software (since the GPL requires that you make your source code available if you incorporate GPL'ed code into your product).

Duel-licensing is a way to accommodate this and also provides a revenue stream for the company providing the software. For users that don't mind the restrictions of the GPL and don't need support, the product is available under an open source license. For users for whom the GPL's restrictions would be incompatible with their business model, and for users that do need support, a commercial license is available.

You gave the specific example of the Screwturn wiki, which is dual-licensed under the GPL and a commercial license. Under the terms of the GPL (i.e., without getting a "commercial" license), you can do the following:

• Use it internally as much as you want (see here)
• Run it on your internal servers for external users / clients / customers, or run it on your internal servers for paying clients if you're an ISP / hosting provider. (If Screwturn were licensed under the AGPL instead of the GPL, that might restrict this.)
• Distribute it to others, either free of charge or for a payment that covers the shipping, as long as you're willing to also distribute the source code
• Incorporate it into your product, as long as you're willing to also distribute the source code, and as long as either (a) it remains a separate program that you merely aggregate with your product or (b) you release the source code to your product under an open source license compatible with the GPL

In other words, there's a lot that you can do without getting a commercial license. This is especially true for web-based software, since people can use web-based software without it being distributed to them. Screwturn's web site even acknowledges this: they state that the commercial license is for "either integrating it in a commercial application, or using it in an enterprise environment where free software is not allowed," not for any use related to commerce.

All of the preceding is merely my understanding and is not intended to be legal advice. Consult your lawyer to be certain.

There is no mistake in your bash script. But you are executing it with sh which has a less extensive syntax ;)

So, run bash ./choose.sh instead :)

I think one reason is that some people feel that the most important part of whether a language will be accepted is how good the language is. Unfortunately, things are rarely so simple. For example, I would argue that the biggest factor behind Python's acceptance isn't the language itself (although that is pretty important). The biggest reason why Python is so popular is its huge standard library and the even bigger community of 3rd party libraries.

Languages like Clojure or F# may be the exception to the rule on this considering that they're built upon the JVM/CLR. As a result, I don't have an answer for them.

protected void Page_Load(object sender, EventArgs e)
    {

                               "this.disabled=true;" + GetPostBackEventReference(btnSave).ToString() + ";");

        // ... etc. 
    }

By far the best option nowadays would be using a maven container as a builder tool. A mvn.sh script like this would be enough:

#!/bin/bash
docker run --rm -ti \
 -v $(pwd):/opt/app \
 -w /opt/app \
 -e TERM=xterm \
 -v $HOME/.m2:/root/.m2 \
 maven mvn "$@"

Try to put stateHidden on as your activity windowSoftInputMode value

http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode

For example for your Activity:

this.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

You can also set LD_RUN_PATH to /usr/local/lib in your user environment when you compile pycurl in the first place. This will embed /usr/local/lib in the RPATH attribute of the C extension module .so so that it automatically knows where to find the library at run time without having to have LD_LIBRARY_PATH set at run time.

other than the fact that String implements CharSequence and that String is a sequence of character.

Several things happen in your code:

CharSequence obj = "hello";

That creates a String literal, "hello", which is a String object. Being a String, which implements CharSequence, it is also a CharSequence. (you can read this post about coding to interface for example).

The next line:

String str = "hello";

is a little more complex. String literals in Java are held in a pool (interned) so the "hello" on this line is the same object (identity) as the "hello" on the first line. Therefore, this line only assigns the same String literal to str.

At this point, both obj and str are references to the String literal "hello" and are therefore equals, == and they are both a String and a CharSequence.

I suggest you test this code, showing in action what I just wrote:

public static void main(String[] args) {
    CharSequence obj = "hello";
    String str = "hello";
    System.out.println("Type of obj: " + obj.getClass().getSimpleName());
    System.out.println("Type of str: " + str.getClass().getSimpleName());
    System.out.println("Value of obj: " + obj);
    System.out.println("Value of str: " + str);
    System.out.println("Is obj a String? " + (obj instanceof String));
    System.out.println("Is obj a CharSequence? " + (obj instanceof CharSequence));
    System.out.println("Is str a String? " + (str instanceof String));
    System.out.println("Is str a CharSequence? " + (str instanceof CharSequence));
    System.out.println("Is \"hello\" a String? " + ("hello" instanceof String));
    System.out.println("Is \"hello\" a CharSequence? " + ("hello" instanceof CharSequence));
    System.out.println("str.equals(obj)? " + str.equals(obj));
    System.out.println("(str == obj)? " + (str == obj));
}

Combining @Ramnath and @Tommy's answers allowed me to find an approach that works in base R for one or more columns.

Basic usage:

> df = data.frame(
+   id=1:3, foo=c('a|b','b|c','c|d'), 
+   bar=c('p|q', 'r|s', 's|t'), stringsAsFactors=F)
> transform(df, test=do.call(rbind, strsplit(foo, '|', fixed=TRUE)), stringsAsFactors=F)
  id foo bar test.1 test.2
1  1 a|b p|q      a      b
2  2 b|c r|s      b      c
3  3 c|d s|t      c      d

Multiple columns:

> transform(df, lapply(list(foo,bar),
+ function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar X1 X2 X1.1 X2.1
1  1 a|b p|q  a  b    p    q
2  2 b|c r|s  b  c    r    s
3  3 c|d s|t  c  d    s    t

Better naming of multiple split columns:

> transform(df, lapply({l<-list(foo,bar);names(l)=c('foo','bar');l}, 
+                          function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar foo.1 foo.2 bar.1 bar.2
1  1 a|b p|q     a     b     p     q
2  2 b|c r|s     b     c     r     s
3  3 c|d s|t     c     d     s     t

This is because of the combination of two things:

  If no "files" property is present in a tsconfig.json, the compiler defaults to including all files in the containing directory and subdirectories. When a "files" property is specified, only those files are included.

• Including typescript as an npm dependency : node_modules/typescript/ This means that all of typescript gets included .... there is an implicitly included lib.d.ts in your project anyways (http://basarat.gitbook.io/typescript/content/docs/types/lib.d.ts.html) and its conflicting with the one that ships with the NPM version of typescript.

Fix

Either list files or include explicitly https://basarat.gitbook.io/typescript/docs/project/files.html

You can also return all the information about the Foreign Keys by adapating @LittleSweetSeas answer:

SELECT 
   OBJECT_NAME(f.parent_object_id) ConsTable,
   OBJECT_NAME (f.referenced_object_id) refTable,
   COL_NAME(fc.parent_object_id,fc.parent_column_id) ColName
FROM 
   sys.foreign_keys AS f
INNER JOIN 
   sys.foreign_key_columns AS fc 
      ON f.OBJECT_ID = fc.constraint_object_id
INNER JOIN 
   sys.tables t 
      ON t.OBJECT_ID = fc.referenced_object_id
order by
ConsTable

You can use

docker history IMAGE_ID

to see how the image size is ditributed between its various sub-components.

popstate event:

The popstate event is fired when the active history entry changes. [...] The popstate event is only triggered by doing a browser action such as a click on the back button (or calling history.back() in JavaScript)

So, listening to popstate event and sending a popstate event when using history.pushState() should be enough to take action on href change:

window.addEventListener('popstate', listener);

const pushUrl = (href) => {
  history.pushState({}, '', href);
  window.dispatchEvent(new Event('popstate'));
};

            Container(
         height: 50,
          // margin: EdgeInsets.only(top: 20),
          decoration: BoxDecoration(
              color: Colors.tealAccent,
              borderRadius: BorderRadius.circular(32)),
          child: TextFormField(
            cursorColor: Colors.black,
            // keyboardType: TextInputType.,
            decoration: InputDecoration(
              hintStyle: TextStyle(fontSize: 17),
              hintText: 'Search your trips',
              suffixIcon: Icon(Icons.search),
              border: InputBorder.none,
              contentPadding: EdgeInsets.all(18),
            ),
          ),
        ),

The other posters are correct you cannot connect to MySQL directly from javascript. This is because JavaScript is at client side & mysql is server side.

So your best bet is to use ajax to call a handler as quoted above if you can let us know what language your project is in we can better help you ie php/java/.net

If you project is using php then the example from Merlyn is a good place to start, I would personally use jquery.ajax() to cut down you code and have a better chance of less cross browser issues.

http://api.jquery.com/jQuery.ajax/

I think you need WaitHandler.WaitAll. Here is an example:

public static void Main(string[] args)
{
    int numOfThreads = 10;
    WaitHandle[] waitHandles = new WaitHandle[numOfThreads];

    for (int i = 0; i < numOfThreads; i++)
    {
        var j = i;
        // Or you can use AutoResetEvent/ManualResetEvent
        var handle = new EventWaitHandle(false, EventResetMode.ManualReset);
        var thread = new Thread(() =>
                                {
                                    Thread.Sleep(j * 1000);
                                    Console.WriteLine("Thread{0} exits", j);
                                    handle.Set();
                                });
        waitHandles[j] = handle;
        thread.Start();
    }
    WaitHandle.WaitAll(waitHandles);
    Console.WriteLine("Main thread exits");
    Console.Read();
}

FCL has a few more convenient functions.

(1) Task.WaitAll, as well as its overloads, when you want to do some tasks in parallel (and with no return values).

var tasks = new[]
{
    Task.Factory.StartNew(() => DoSomething1()),
    Task.Factory.StartNew(() => DoSomething2()),
    Task.Factory.StartNew(() => DoSomething3())
};
Task.WaitAll(tasks);

(2) Task.WhenAll when you want to do some tasks with return values. It performs the operations and puts the results in an array. It's thread-safe, and you don't need to using a thread-safe container and implement the add operation yourself.

var tasks = new[]
{
    Task.Factory.StartNew(() => GetSomething1()),
    Task.Factory.StartNew(() => GetSomething2()),
    Task.Factory.StartNew(() => GetSomething3())
};
var things = Task.WhenAll(tasks);

Had a similar problem and was getting the following errors depending on what app I used and if we bypassed the firewall / load balancer or not:

HTTPS handshake to [blah] (for #136) failed. System.IO.IOException Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

and

ReadResponse() failed: The server did not return a complete response for this request. Server returned 0 bytes.

The problem turned out to be that the SSL Server Certificate got missed and wasn't installed on a couple servers.

You can do that by applying your rotate CSS to an inner element and then adjusting the height of the element to match its width since the element was rotated to fit it into the <td>.

Also make sure you change your id #rotate to a class since you have multiple.

$(document).ready(function() {_x000D_
  $('.rotate').css('height', $('.rotate').width());_x000D_
});

JavaScript

The equivalent to the above in pure JavaScript is as follows:

jsFiddle

window.addEventListener('load', function () {
    var rotates = document.getElementsByClassName('rotate');
    for (var i = 0; i < rotates.length; i++) {
        rotates[i].style.height = rotates[i].offsetWidth + 'px';
    }
});

This function will clone remote repo into local repo dir, after merging all commits will be saved, git log will be show the original commits and proper paths:

function git-add-repo
{
    repo="$1"
    dir="$(echo "$2" | sed 's/\/$//')"
    path="$(pwd)"

    tmp="$(mktemp -d)"
    remote="$(echo "$tmp" | sed 's/\///g'| sed 's/\./_/g')"

    git clone "$repo" "$tmp"
    cd "$tmp"

    git filter-branch --index-filter '
        git ls-files -s |
        sed "s,\t,&'"$dir"'/," |
        GIT_INDEX_FILE="$GIT_INDEX_FILE.new" git update-index --index-info &&
        mv "$GIT_INDEX_FILE.new" "$GIT_INDEX_FILE"
    ' HEAD

    cd "$path"
    git remote add -f "$remote" "file://$tmp/.git"
    git pull "$remote/master"
    git merge --allow-unrelated-histories -m "Merge repo $repo into master" --edit "$remote/master"
    git remote remove "$remote"
    rm -rf "$tmp"
}

How to use:

cd current/package
git-add-repo https://github.com/example/example dir/to/save

If make a little changes you can even move files/dirs of merged repo into different paths, for example:

repo="https://github.com/example/example"
path="$(pwd)"

tmp="$(mktemp -d)"
remote="$(echo "$tmp" | sed 's/\///g' | sed 's/\./_/g')"

git clone "$repo" "$tmp"
cd "$tmp"

git pull "$remote/master"
git merge --allow-unrelated-histories -m "Merge repo $repo into master" --edit "$remote/master"

rm -rf "$tmp"

Notices
Paths replaces via sed, so make sure it moved in proper paths after merging.
The --allow-unrelated-histories parameter only exists since git >= 2.9.

Using management studio the procedure can be done as follows

1. right click on the Databases container within object explorer
2. from context menu select Restore database
3. Specify To Database as either a new or existing database
4. Specify Source for restore as from device
5. Select Backup media as File
6. Click the Add button and browse to the location of the BAK file

refer

You'll need to specify the WITH REPLACE option to overwrite the existing adventure_second database with a backup taken from a different database.

Click option menu and tick Overwrite the existing database(With replace)

Reference

For OS X my connection.xml files are in

/Users/<username>/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection.<oracle_version?>/

This is my benchmark results

test 4,267,740 ops/sec ±1.32% (60 runs sampled)

exec 3,649,719 ops/sec ±2.51% (60 runs sampled)

match 3,623,125 ops/sec ±1.85% (62 runs sampled)

indexOf 6,230,325 ops/sec ±0.95% (62 runs sampled)

test method is faster than the match method, but the fastest method is the indexOf

See from How to Replace String in File works in a simple way and is an answer that works with replace

fin = open("data.txt", "rt")
fout = open("out.txt", "wt")

for line in fin:
    fout.write(line.replace('pyton', 'python'))

fin.close()
fout.close()

There is another (faster?) way to find where your app data is without Terminal:

1. Launch the app in the simulator
2. Open Activity Monitor
3. Find the name of your app in the CPU tab
4. Double-click it and open the "Open Files and Ports"

If you are using other version control software, it may be in conflict. In my case, uninstalling Plastic SCM restored Tortoise SVN icons.

this should work.

TextView t2 = (TextView) findViewById(R.id.text2);
t2.setMovementMethod(LinkMovementMethod.getInstance());

and

<TextView android:layout_width="wrap_content"

android:id="@+id/text2"
 android:layout_centerInParent="true"
android:layout_marginTop="20dp"></TextView>

By using typed arrays, you can store arrays of these types:

• Int8
• Uint8
• Int16
• Uint16
• Int32
• Uint32
• Float32
• Float64

For example:

?var array = new Uint8Array(100);
array[42] = 10;
alert(array[42]);?

Reference to HEAD is not necessary.

git checkout -- file.js is sufficient

What is the __main__.py file for?

When creating a Python module, it is common to make the module execute some functionality (usually contained in a main function) when run as the entry point of the program. This is typically done with the following common idiom placed at the bottom of most Python files:

if __name__ == '__main__':
    # execute only if run as the entry point into the program
    main()

You can get the same semantics for a Python package with __main__.py, which might have the following structure:

.
+-- demo
    +-- __init__.py
    +-- __main__.py

To see this, paste the below into a Python 3 shell:

from pathlib import Path

demo = Path.cwd() / 'demo'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo/__main__.py executed')

from demo import main

main()
""")

We can treat demo as a package and actually import it, which executes the top-level code in the __init__.py (but not the main function):

>>> import demo
demo/__init__.py executed

When we use the package as the entry point to the program, we perform the code in the __main__.py, which imports the __init__.py first:

$ python -m demo
demo/__init__.py executed
demo/__main__.py executed
main() executed

You can derive this from the documentation. The documentation says:

__main__ — Top-level script environment

'__main__' is the name of the scope in which top-level code executes. A module’s __name__ is set equal to '__main__' when read from standard input, a script, or from an interactive prompt.

A module can discover whether or not it is running in the main scope by checking its own __name__, which allows a common idiom for conditionally executing code in a module when it is run as a script or with python -m but not when it is imported:

if __name__ == '__main__':
     # execute only if run as a script
     main()

For a package, the same effect can be achieved by including a __main__.py module, the contents of which will be executed when the module is run with -m.

Zipped

You can also zip up this directory, including the __main__.py, into a single file and run it from the command line like this - but note that zipped packages can't execute sub-packages or submodules as the entry point:

from pathlib import Path

demo = Path.cwd() / 'demo2'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo2/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo2/__main__.py executed')

from __init__ import main

main()
""")

Note the subtle change - we are importing main from __init__ instead of demo2 - this zipped directory is not being treated as a package, but as a directory of scripts. So it must be used without the -m flag.

Particularly relevant to the question - zipapp causes the zipped directory to execute the __main__.py by default - and it is executed first, before __init__.py:

$ python -m zipapp demo2 -o demo2zip
$ python demo2zip
demo2/__main__.py executed
demo2/__init__.py executed
main() executed

Note again, this zipped directory is not a package - you cannot import it either.

The aggregate root is a complex name for a simple idea.

General idea

Well designed class diagram encapsulates its internals. Point through which you access this structure is called aggregate root.

Internals of your solution may be very complicated, but users of this hierarchy will just use root.doSomethingWhichHasBusinessMeaning().

Example

Check this simple class hierarchy

How do you want to ride your car? Chose better API

Option A (it just somehow works):

car.ride();

Option B (user has access to class inernals):

if(car.getTires().getUsageLevel()< Car.ACCEPTABLE_TIRE_USAGE)
    for (Wheel w: car:getWheels()){
        w.spin();
    }
}

If you think that option A is better then congratulations. You get the main reason behind aggregate root.

Aggregate root encapsulates multiple classes. you can manipulate the whole hierarchy only through the main object.

In general this is a very subtle issue and not trivial whatsoever. I encourage you to read mysqlperformanceblog.com and High Performance MySQL. I really think there is no general answer for this.

I'm working on a project which has a MySQL database with almost 1TB of data. The most important scalability factor is RAM. If the indexes of your tables fit into memory and your queries are highly optimized, you can serve a reasonable amount of requests with a average machine.

The number of records do matter, depending of how your tables look like. It's a difference to have a lot of varchar fields or only a couple of ints or longs.

The physical size of the database matters as well: think of backups, for instance. Depending on your engine, your physical db files on grow, but don't shrink, for instance with innodb. So deleting a lot of rows, doesn't help to shrink your physical files.

There's a lot to this issues and as in a lot of cases the devil is in the details.

I had the same problem. Go to Project Properties -> Deployment Assemplbly and add jstl jar

VARCHAR(MAX) is big enough to accommodate TEXT field. TEXT, NTEXT and IMAGE data types of SQL Server 2000 will be deprecated in future version of SQL Server, SQL Server 2005 provides backward compatibility to data types but it is recommended to use new data types which are VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX).

I just used the @misir-jafarov and is working now with :

• IE 8,9,10,11 and EDGE detection
• used in Bootrap 4
• take the height of its parent div
• cliped vertically at 20% of top and horizontally 50% (better for portraits)

here is my code :

if (document.documentMode || /Edge/.test(navigator.userAgent)) {
    jQuery('.art-img img').each(function(){
        var t = jQuery(this),
            s = 'url(' + t.attr('src') + ')',
            p = t.parent(),
            d = jQuery('<div></div>');

        p.append(d);
        d.css({
            'height'                : t.parent().css('height'),
            'background-size'       : 'cover',
            'background-repeat'     : 'no-repeat',
            'background-position'   : '50% 20%',
            'background-image'      : s
        });
        t.hide();
    });
}

Hope it helps.

Use the System.getenv(String) method, passing the name of the variable to read.

This worked for me in Xamarin.iOS / Monotouch. Change the keyboard button to Next, pass the control to the next UITextField and hide the keyboard after the last UITextField.

private void SetShouldReturnDelegates(IEnumerable<UIView> subViewsToScout )
{
  foreach (var item in subViewsToScout.Where(item => item.GetType() == typeof (UITextField)))
  {
    (item as UITextField).ReturnKeyType = UIReturnKeyType.Next;
    (item as UITextField).ShouldReturn += (textField) =>
    {
        nint nextTag = textField.Tag + 1;
        var nextResponder = textField.Superview.ViewWithTag(nextTag);
        if (null != nextResponder)
            nextResponder.BecomeFirstResponder();
        else
            textField.Superview.EndEditing(true); 
            //You could also use textField.ResignFirstResponder(); 

        return false; // We do not want UITextField to insert line-breaks.
    };
  }
}

Inside the ViewDidLoad you'll have:

If your TextFields haven't a Tag set it now:

txtField1.Tag = 0;
txtField2.Tag = 1;
txtField3.Tag = 2;
//...

and just the call

SetShouldReturnDelegates(yourViewWithTxtFields.Subviews.ToList());
//If you are not sure of which view contains your fields you can also call it in a safer way:
SetShouldReturnDelegates(txtField1.Superview.Subviews.ToList());
//You can also reuse the same method with different containerViews in case your UITextField are under different views.

There are many different sytles/conventions that people use when coding C++. For example, some people prefer separating words using capitals (myVar or MyVar), or using underscores (my_var). Typically, variables that use underscores are in all lowercase (from my experience).
There is also a coding style called hungarian, which I believe is used by microsoft. I personally believe that it is a waste of time, but it may prove useful. This is were variable names are given short prefixes such as i, or f to hint the variables type. For example: int iVarname, char* strVarname.

It is accepted that you end a struct/class name with _t, to differentiate it from a variable name. E.g.:

class cat_t {
  ...
};

cat_t myCat;

It is also generally accepted to add a affix to indicate pointers, such as pVariable or variable_p.

In all, there really isn't any single standard, but many. The choices you make about naming your variables doesn't matter, so long as it is understandable, and above all, consistent. Consistency, consistency, CONSISTENCY! (try typing that thrice!)

And if all else fails, google it.

Based on Tom Gullen´s answer.

var start = new Date("02/05/2013");
var end = new Date("02/10/2013");


var loop = new Date(start);
while(loop <= end){
   alert(loop);           

   var newDate = loop.setDate(loop.getDate() + 1);
   loop = new Date(newDate);
}

Your select doesn't have an ID, only a name. You'll need to modify your selector:

$("#pizza").on("click", function(){
  $("select[name='pizza_kind']").prop("disabled", !this.checked);
});

Demo: http://jsbin.com/imokuj/2/edit

A printer doesn't understand pixels, it understand dots (pt in CSS). The best solution is to write an extra CSS for printing, with all of its measures in dots.

Then, in your HTML code, in head section, put:

<link href="style.css" rel="stylesheet" type="text/css" media="screen">
<link href="style_print.css" rel="stylesheet" type="text/css" media="print">

The port is usually fixed, for DNS it's 53.

When I ran into this problem, trying to run an async method synchronicity from either a setter or a constructor got me into a deadlock on the UI thread, and using an event handler required too many changes in the general design.
The solution was, as often is, to just write explicitly what I wanted to happen implicitly, which was to have another thread handle the operation and to get the main thread to wait for it to finish:

string someValue=null;
var t = new Thread(() =>someValue = SomeAsyncMethod().Result);
t.Start();
t.Join();

You could argue that I abuse the framework, but it works.

Static members are universal members. They can be accessed from anywhere.

I'm not sure this solution is under the spec but I think I can share for others.

dependency tree

my-entities.jar

Contains entity classes only. No META-INF/persistence.xml.

my-services.jar

Depends on my-entities. Contains EJBs only.

my-resources.jar

Depends on my-services. Contains resource classes and META-INF/persistence.xml.

problems

• How can we specify <jar-file/> element in my-resources as the version-postfixed artifact name of a transient dependency?
• How can we sync the <jar-file/> element's value and the actual transient dependency's one?

solution

direct (redundant?) dependency and resource filtering

I put a property and a dependency in my-resources/pom.xml.

<properties>
  <my-entities.version>x.y.z-SNAPSHOT</my-entities.version>
</properties>
<dependencies>
  <dependency>
    <!-- this is actually a transitive dependency -->
    <groupId>...</groupId>
    <artifactId>my-entities</artifactId>
    <version>${my-entities.version}</version>
    <scope>compile</scope> <!-- other values won't work -->
  </dependency>
  <dependency>
    <groupId>...</groupId>
    <artifactId>my-services</artifactId>
    <version>some.very.sepecific</version>
    <scope>compile</scope>
  </dependency>
<dependencies>

Now get the persistence.xml ready for being filtered

<?xml version="1.0" encoding="UTF-8"?>
<persistence ...>

A new array is created and the contents of the old one are copied over. That's all you know at the API level. Quoting from the docs (my emphasis):

Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically. The details of the growth policy are not specified beyond the fact that adding an element has constant amortized time cost.

In terms of how it actually happens with a specific implementation of ArrayList (such as Sun's), in their case you can see the gory details in the source. But of course, relying on the details of a specific implementation isn't usually a good idea...

syntax: git reflog --date=local | grep checkout: | grep ${current_branch} | tail -1

example: git reflog --date=local | grep checkout: | grep dev-2.19.0 | tail -1

result: cc7a3a8ec HEAD@{Wed Apr 29 14:58:50 2020}: checkout: moving from dev-2.18.0 to dev-2.19.0

curl probably does have some options for showing more information but for things like this I always use openssl s_client

With the -debug option this gives lots of useful information

Maybe I should add that this also works with non HTTP connections. So if you are doing "https", try the curl commands suggested below. If you aren't or want a second option openssl s_client might be good

Ahem, because 22 is the port number for ssh and has been for ages?

SupressFinalize tells the system that whatever work would have been done in the finalizer has already been done, so the finalizer doesn't need to be called. From the .NET docs:

Objects that implement the IDisposable interface can call this method from the IDisposable.Dispose method to prevent the garbage collector from calling Object.Finalize on an object that does not require it.

In general, most any Dispose() method should be able to call GC.SupressFinalize(), because it should clean up everything that would be cleaned up in the finalizer.

SupressFinalize is just something that provides an optimization that allows the system to not bother queuing the object to the finalizer thread. A properly written Dispose()/finalizer should work properly with or without a call to GC.SupressFinalize().

he does an integer divide, which means 3 / 4 = 0. cast one of the brackets to float

 (float)(a.y - b.y) / (a.x - b.x);

I hope below solution will work for you all as I was having the same problem with my websites...

For : $json = json_decode(file_get_contents('http://...'));

Replace with below query

$Details= unserialize(file_get_contents('http://......'));

It also happens when the view returned by onCreateView() isn't the view that was inflated.

Example:

View rootView = inflater.inflate(R.layout.my_fragment, container, false);

TextView textView = (TextView) rootView.findViewById(R.id.text_view);
textView.setText("Some text.");

return textView;

Fix:

return rootView;

Instead of:

return textView; // or whatever you returned

You might like the function GetInfoFromClosedFile()

Edit: Since the above link does not seem to work anymore, I am adding alternate link 1 and alternate link 2 + code:

Private Function GetInfoFromClosedFile(ByVal wbPath As String, _
    wbName As String, wsName As String, cellRef As String) As Variant
Dim arg As String
    GetInfoFromClosedFile = ""
    If Right(wbPath, 1) <> "" Then wbPath = wbPath & ""
    If Dir(wbPath & "" & wbName) = "" Then Exit Function
    arg = "'" & wbPath & "[" & wbName & "]" & _
        wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1)
    On Error Resume Next
    GetInfoFromClosedFile = ExecuteExcel4Macro(arg)
End Function

Use css calc()

Super simple and awesome.

input {
    width: -moz-calc(100% - 15px);
    width: -webkit-calc(100% - 15px);
    width: calc(100% - 15px);
}?

Just copied this over here, because I almost missed it in the other thread.

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

This operation is a complement, not a negation.

Consider that ~0 = -1, and work from there.

The algorithm for negation is, "complement, increment".

Did you know? There is also "one's complement" where the inverse numbers are symmetrical, and it has both a 0 and a -0.

Try this.

SELECT 
  CASE 
     WHEN FRUIT = 'A' THEN 'APPLE'
     WHEN FRUIT = 'B' THEN 'BANANA'
     ELSE 'UNKNOWN FRUIT'
  END AS FRUIT
FROM FRUIT_TABLE;

If your integer is timestamp in milliseconds use:

SELECT strftime("%Y-%d-%m", col_name, 'unixepoch') AS col_name

It will format milliseconds to yyyy-mm-dd string.

i have a data access library which works with both .net core and .net framework.

the trick was in .net core projects to keep the connection strings in a xml file named "app.config" (also for web projects), and mark it as 'copy to output directory',

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="conn1" connectionString="...." providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

ConfigurationManager.ConnectionStrings - will read the connection string.

    var conn1 = ConfigurationManager.ConnectionStrings["conn1"].ConnectionString;

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

This is Pythons way do show you unicode encoded strings. But i think you should be able to print the string on the screen or write it into a new file without any problems.

>>> test = u"I don\u2018t like this"
>>> test
u'I don\u2018t like this'
>>> print test
I don‘t like this

The beauty of C++, like C, is that the sized of these things are implementation-defined, so there's no correct answer without your specifying the compiler you're using. Are those two the same? Yes. "long long" is a synonym for "long long int", for any compiler that will accept both.

<input type="text" value="3" class="field left" readonly>

You could see in https://www.w3schools.com/tags/att_input_readonly.asp

The method to set "readonly":

$("input").attr("readonly", true)

to cancel "readonly"(work in jQuery):

$("input").attr("readonly", false)

Here's an approach using the URL() interface:

new URL(location.pathname, location.href).href

Extending Piotr's answer, if you also need a way to figure what to put in requirements.in, you can first use pip-chill to find the minimal set of required packages you have. By combining these tools, you can show the dependency reason why each package is installed. The full cycle looks like this:

1. Create virtual environment:
   $ python3 -m venv venv
2. Activate it:
   $ . venv/bin/activate
3. Install newest version of pip, pip-tools and pip-chill:
   (venv)$ pip install --upgrade pip
(venv)$ pip install pip-tools pip-chill
4. Build your project, install more pip packages, etc, until you want to save...
5. Extract minimal set of packages (ie, top-level without dependencies):
   (venv)$ pip-chill --no-version > requirements.in
6. Compile list of all required packages (showing dependency reasons):
   (venv)$ pip-compile requirements.in
7. Make sure the current installation is synchronized with the list:
   (venv)$ pip-sync

Try the following:

create these folders under storage/framework:

• sessions
• views
• cache

Now it should work

To me, the following is more readable (thus preferable) way to do it:

git reset HEAD~1

Instead of 1, there could be any number of commits you want to unstage.

There is no existing Swap-method, so you have to create one yourself. Of course you can linqify it, but that has to be done with one (unwritten?) rules in mind: LINQ-operations do not change the input parameters!

In the other "linqify" answers, the (input) list is modified and returned, but this action brakes that rule. If would be weird if you have a list with unsorted items, do a LINQ "OrderBy"-operation and than discover that the input list is also sorted (just like the result). This is not allowed to happen!

So... how do we do this?

My first thought was just to restore the collection after it was finished iterating. But this is a dirty solution, so do not use it:

static public IEnumerable<T> Swap1<T>(this IList<T> source, int index1, int index2)
{
    // Parameter checking is skipped in this example.

    // Swap the items.
    T temp = source[index1];
    source[index1] = source[index2];
    source[index2] = temp;

    // Return the items in the new order.
    foreach (T item in source)
        yield return item;

    // Restore the collection.
    source[index2] = source[index1];
    source[index1] = temp;
}

This solution is dirty because it does modify the input list, even if it restores it to the original state. This could cause several problems:

1. The list could be readonly which will throw an exception.
2. If the list is shared by multiple threads, the list will change for the other threads during the duration of this function.
3. If an exception occurs during the iteration, the list will not be restored. (This could be resolved to write an try-finally inside the Swap-function, and put the restore-code inside the finally-block).

There is a better (and shorter) solution: just make a copy of the original list. (This also makes it possible to use an IEnumerable as a parameter, instead of an IList):

static public IEnumerable<T> Swap2<T>(this IList<T> source, int index1, int index2)
{
    // Parameter checking is skipped in this example.

    // If nothing needs to be swapped, just return the original collection.
    if (index1 == index2)
        return source;

    // Make a copy.
    List<T> copy = source.ToList();

    // Swap the items.
    T temp = copy[index1];
    copy[index1] = copy[index2];
    copy[index2] = temp;

    // Return the copy with the swapped items.
    return copy;
}

One disadvantage of this solution is that it copies the entire list which will consume memory and that makes the solution rather slow.

You might consider the following solution:

static public IEnumerable<T> Swap3<T>(this IList<T> source, int index1, int index2)
{
    // Parameter checking is skipped in this example.
    // It is assumed that index1 < index2. Otherwise a check should be build in and both indexes should be swapped.

    using (IEnumerator<T> e = source.GetEnumerator())
    {
        // Iterate to the first index.
        for (int i = 0; i < index1; i++)
            yield return source[i];

        // Return the item at the second index.
        yield return source[index2];

        if (index1 != index2)
        {
            // Return the items between the first and second index.
            for (int i = index1 + 1; i < index2; i++)
                yield return source[i];

            // Return the item at the first index.
            yield return source[index1];
        }

        // Return the remaining items.
        for (int i = index2 + 1; i < source.Count; i++)
            yield return source[i];
    }
}

And if you want to input parameter to be IEnumerable:

static public IEnumerable<T> Swap4<T>(this IEnumerable<T> source, int index1, int index2)
{
    // Parameter checking is skipped in this example.
    // It is assumed that index1 < index2. Otherwise a check should be build in and both indexes should be swapped.

    using(IEnumerator<T> e = source.GetEnumerator())
    {
        // Iterate to the first index.
        for(int i = 0; i < index1; i++) 
        {
            if (!e.MoveNext())
                yield break;
            yield return e.Current;
        }

        if (index1 != index2)
        {
            // Remember the item at the first position.
            if (!e.MoveNext())
                yield break;
            T rememberedItem = e.Current;

            // Store the items between the first and second index in a temporary list. 
            List<T> subset = new List<T>(index2 - index1 - 1);
            for (int i = index1 + 1; i < index2; i++)
            {
                if (!e.MoveNext())
                    break;
                subset.Add(e.Current);
            }

            // Return the item at the second index.
            if (e.MoveNext())
                yield return e.Current;

            // Return the items in the subset.
            foreach (T item in subset)
                yield return item;

            // Return the first (remembered) item.
            yield return rememberedItem;
        }

        // Return the remaining items in the list.
        while (e.MoveNext())
            yield return e.Current;
    }
}

Swap4 also makes a copy of (a subset of) the source. So worst case scenario, it is as slow and memory consuming as function Swap2.

The whole point of using a mapping technology like Jackson is that you can use Objects (you don't have to parse the JSON yourself).

Define a Java class that resembles the JSON you will be expecting.

e.g. this JSON:

{
"foo" : ["abc","one","two","three"],
"bar" : "true",
"baz" : "1"
}

could be mapped to this class:

public class Fizzle{
    private List<String> foo;
    private boolean bar;
    private int baz;
    // getters and setters omitted
}

Now if you have a Controller method like this:

@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
    return new Fozzle(input);
}

and you pass in the JSON from above, Jackson will automatically create a Fizzle object for you, and it will serialize a JSON view of the returned Object out to the response with mime type application/json.

For a full working example see this previous answer of mine.

For easy tasks I often simply do it like:

var undef;

// Fails on undefined variables
if (query !== undef) {
    // variable is defined
} else {
    // else do this
}

Or if you simply want to check for a nulled value too..

var undef;

// Fails on undefined variables
// And even fails on null values
if (query != undef) {
    // variable is defined and not null
} else {
    // else do this
}

You have mixed 2 standard.

The error is in $header = "Content-Type: multipart/form-data; boundary='123456f'";

The function http_build_query($filedata) is only for "Content-Type: application/x-www-form-urlencoded", or none.

This is a subjective opinion, but I think a text editor shouldn't do everything and the kitchen sink. I prefer lightweight flexible and powerful (in their specialized fields) editors. Although being mostly a Windows user, I like the Unix philosophy of having lot of specialized tools that you can pipe together (like the UnxUtils) rather than a monster doing everything, but not necessarily as you would like it!

Find in files is on the border of these extra features, but useful when you can double-click on a found line to open the file at the right line. Note that initially, in SciTE it was just a Tools call to grep or equivalent!
FTP is very close to off topic, although it can be seen as an extended open/save dialog.
Replace in files is too much IMO: it is dangerous (you can mess lot of files at once) if you have no preview, etc. I would rather use a specialized tool I chose, perhaps among those in Multi line search and replace tool.

To answer the question, looking at N++, I see a Run menu where you can launch any tool, with assignment of a name and shortcut key. I see also Plugins > NppExec, which seems able to launch stuff like sed (not tried it).

You can use the built-in forEach function for arrays.

Like this:

//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
    element.product_desc = element.product_desc.substring(0,10);
});

Your version wasn't wrong though. It should look more like this:

for(let i=0; i<data.products.length; i++){
    console.log(data.products[i].product_desc); //use i instead of 0
}

== and .Equals are both dependent upon the behavior defined in the actual type and the actual type at the call site. Both are just methods / operators which can be overridden on any type and given any behavior the author so desires. In my experience, I find it's common for people to implement .Equals on an object but neglect to implement operator ==. This means that .Equals will actually measure the equality of the values while == will measure whether or not they are the same reference.

When I'm working with a new type whose definition is in flux or writing generic algorithms, I find the best practice is the following

• If I want to compare references in C#, I use Object.ReferenceEquals directly (not needed in the generic case)
• If I want to compare values I use EqualityComparer<T>.Default

In some cases when I feel the usage of == is ambiguous I will explicitly use Object.Reference equals in the code to remove the ambiguity.

Eric Lippert recently did a blog post on the subject of why there are 2 methods of equality in the CLR. It's worth the read

There's a function empty() ready for you in std::string:

std::string a;
if(a.empty())
{
    //do stuff. You will enter this block if the string is declared like this
}

or

std::string a;
if(!a.empty())
{
    //You will not enter this block now
}
a = "42";
if(!a.empty())
{
    //And now you will enter this block.
}

For input elements, this answer works for me.

I implemented it on a custom input component in Angular 4, but I think it could be implemented with pure JS.

HTML

<input type="text" [(ngModel)]="value" (ondragenter)="disableEvent($event)" 
(dragover)="disableEvent($event)" (ondrop)="disableEvent($event)"/>

Component definition (JS):

export class CustomInputComponent { 

  //component construction and attribute definitions

  disableEvent(event) {
    event.preventDefault();
    return false;
  }
}

If body contains a io.StringIO, you have to do like below:

object.get()['Body'].getvalue()

Declaring a two dimensional ArrayList:

ArrayList<ArrayList<String>> rows = new ArrayList<String>();

Or

ArrayList<ArrayList<String>> rows = new ArrayList<>();

Or

ArrayList<ArrayList<String>> rows = new ArrayList<ArrayList<String>>(); 

All the above are valid declarations for a two dimensional ArrayList!

Now, Declaring a one dimensional ArrayList:

ArrayList<String> row = new ArrayList<>();

Inserting values in the two dimensional ArrayList:

for(int i=0; i<5; i++){
    ArrayList<String> row = new ArrayList<>();
    for(int j=0; j<5; j++){
        row.add("Add values here"); 
    }
    rows.add(row); 
}

fetching the values from the two dimensional ArrayList:

for(int i=0; i<5; i++){
    for(int j=0; j<5; j++){
        System.out.print(rows.get(i).get(j)+" ");
     }
     System.out.println("");
}

In short, find the element in the scrollView that you want to scroll to, and use scrollIntoView.

el.scrollIntoView({behavior:"smooth"});

Here is a plunkr.

For those who want to use JavaMail with Kotlin in 2020:

First: Add these dependencies to your build.gradle file (official JavaMail Maven Dependencies)

implementation 'com.sun.mail:android-mail:1.6.5'

implementation 'com.sun.mail:android-activation:1.6.5'

implementation "org.bouncycastle:bcmail-jdk15on:1.65"

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.7"

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.7"

BouncyCastle is for security reasons.

Second: Add these permissions to your AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Third: When using SMTP, create a Config file

object Config {
    const val EMAIL_FROM = "[email protected]"
    const val PASS_FROM = "Your_Sender_Password"

    const val EMAIL_TO = "[email protected]"
}

Fourth: Create your Mailer Object

object Mailer {

init {
    Security.addProvider(BouncyCastleProvider())
}

private fun props(): Properties = Properties().also {
        // Smtp server
        it["mail.smtp.host"] = "smtp.gmail.com"
        // Change when necessary
        it["mail.smtp.auth"] = "true"
        it["mail.smtp.port"] = "465"
        // Easy and fast way to enable ssl in JavaMail
        it["mail.smtp.ssl.enable"] = true
    }

// Dont ever use "getDefaultInstance" like other examples do!
private fun session(emailFrom: String, emailPass: String): Session = Session.getInstance(props(), object : Authenticator() {
    override fun getPasswordAuthentication(): PasswordAuthentication {
        return PasswordAuthentication(emailFrom, emailPass)
    }
})

            <b>Surname:</b> $surName <br/>
        """.trimIndent()
}

private fun builtSubject(issue: String, firstName: String, surName: String):String {
    return """
            $issue | $firstName, $surName
        """.trimIndent()
}

private fun sendMessageTo(emailFrom: String, session: Session, message: String, subject: String) {
    try {
        MimeMessage(session).let { mime ->
            mime.setFrom(InternetAddress(emailFrom))
            // Adding receiver
            mime.addRecipient(Message.RecipientType.TO, InternetAddress(Config.EMAIL_TO))
            // Adding subject
            mime.subject = subject
            // Adding message
            mime.setText(message)
            // Set Content of Message to Html if needed
            mime.setContent(message, "text/html")
            // send mail
            Transport.send(mime)
        }

    } catch (e: MessagingException) {
        Log.e("","") // Or use timber, it really doesn't matter
    }
}

fun sendMail(firstName: String, surName: String) {
        // Open a session
        val session = session(Config.EMAIL_FROM, Config.PASSWORD_FROM)

        // Create a message
        val message = builtMessage(firstName, surName)

        // Create subject
        val subject = builtSubject(firstName, surName)

        // Send Email
        CoroutineScope(Dispatchers.IO).launch { sendMessageTo(Config.EMAIL_FROM, session, message, subject) }
}

Note

• If you want a more secure way to send your email (and you want a more secure way!), use http as mentioned in the solutions before (I will maybe add it later in this answer)
• You have to properly check, if the users phone has internet access, otherwise the app will crash.
• When using gmail, enable "less secure apps" (this will not work, when you gmail has two factors enabled) https://myaccount.google.com/lesssecureapps?pli=1
• Some credits belong to: https://medium.com/@chetan.garg36/android-send-mails-not-intent-642d2a71d2ee (he used RxJava for his solution)

I prefer to just return a null, and rely on the caller to handle it appropriately. The (for lack of a better word) exception is if I am absolutely 'certain' this method will return an object. In that case a failure is an exceptional should and should throw.

If the time is 11:03, then the accepted answer will print 11:3.

You could zero-pad the minutes:

"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)

Or go another way and use tdate.time() and only take the hour/minute part:

str(tdate.time())[0:5]

What worked for me on an Amazon EC2 server was:

sudo service mysqld restart

If you are using the push_back there is no call for the string constructor. Otherwise it will create a string object via casting, then it will add the character in this string to the other string. Too much trouble for a tiny character ;)

Since Node v11.0.0 fs promises are available natively without promisify:

const fs = require('fs').promises;
async function loadMonoCounter() {
    const data = await fs.readFile("monolitic.txt", "binary");
    return new Buffer(data);
}

You can overcome this error in two simple ways

First way

using namespace std;
include <string>
// then you can use string class the normal way

Second way

// after including the class string in your cpp file as follows
include <string>
/*Now when you are using a string class you have to put **std::** before you write 
string as follows*/
std::string name; // a string declaration

When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki

SELECT mac, creation_date 
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
  SELECT *
  FROM consols nx
  WHERE nx.mac = lo.mac
  );

according the documentation, this should do it...

RESET QUERY CACHE 

From the command run:

sudo docker build -t myrepo/redis

there are no "arguments" passed to the docker build command, only a single flag -t and a value for that flag. After docker parses all of the flags for the command, there should be one argument left when you're running a build.

That argument is the build context. The standard command includes a trailing dot for the context:

sudo docker build -t myrepo/redis .

What's the build context?

Every docker build sends a directory to the build server. Docker is a client/server application, and the build runs on the server which isn't necessarily where the docker command is run. Docker uses the build context as the source for files used in COPY and ADD steps. When you are in the current directory to run the build, you would pass a . for the context, aka the current directory. You could pass a completely different directory, even a git repo, and docker will perform the build using that as the context, e.g.:

docker build -t sudobmitch/base:alpine --target alpine-base \
  'https://github.com/sudo-bmitch/docker-base.git#main'

For more details on these options to the build command, see the docker build documentation.

What if you included an argument?

If you are including the value for the build context (typically the .) and still see this error message, you have likely passed more than one argument. Typically this is from failing to parse a flag, or passing a string with spaces without quotes. Possible causes for docker to see more than one argument include:

• Missing quotes around a path or argument with spaces (take note using variables that may have spaces in them)

• Incorrect dashes in the command: make sure to type these manually rather than copy and pasting

• Incorrect quotes: smart quotes don't work on the command line, type them manually rather than copy and pasting.

• Whitespace that isn't white space, or that doesn't appear to be a space.

Most all of these come from either a typo or copy and pasting from a source that modified the text to look pretty, breaking it for using as a command.

How do you figure out where the CLI error is?

The easiest way I have to debug this, run the command without any other flags:

docker build .

Once that works, add flags back in until you get the error, and then you'll know what flag is broken and needs the quotes to be fixed/added or dashes corrected, etc.

I'd suggest using TradeKing's developer API. It is very good and free to use. All that is required is that you have an account with them and to my knowledge you don't have to carry a balance ... only to be registered.

You can try

$('#id1 p').each(function() {
    var text = $(this).text();
    $(this).text(text.replace('dog', 'doll')); 
});

http://jsfiddle.net/2EvGF/

You could use instead .html() and/or further sophisticate the .replace() call according to your needs

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

[EDITED] It's seems you earlier have redefined "list", using it as a variable name, like this:

list = set([1,2,3,4]) # oops
#...
first_list = [1,2,3,4]
my_set=set(first_list)
my_list = list(my_set)

And you'l get

Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'set' object is not callable

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

wmic bios get serialnumber     

if run from a command line (start-run should also do the trick) prints out on screen the Serial Number of the product,
(for example in a toshiba laptop it would print out the serial number of the laptop.
with this serial number you can then identify your laptop model if you need ,from the makers service website-usually..:):)

I had to do exactly that.:):)

Example:

$number = 4;
print "You have the {$number}th edition book";
//output: "You have the 4th edition book";

Without curly braces PHP would try to find a variable named $numberth, that doesn't exist!

I have the same issue as you, after trying all the clean, update and install and there was still missing artifacts. Problem for me is that profiles are not being applied. Check in your .m2/settings.xml and look for <activeProfile>. Go back to your project, right click under properties -> maven and enter your Active Maven Profiles. All the missing artifacts were resolved.

Suppose you simply don't know the size of the data.frame in advance. It can well be a few rows, or a few millions. You need to have some sort of container, that grows dynamically. Taking in consideration my experience and all related answers in SO I come with 4 distinct solutions:

1. rbindlist to the data.frame

2. Use data.table's fast set operation and couple it with manually doubling the table when needed.

3. Use RSQLite and append to the table held in memory.

4. data.frame's own ability to grow and use custom environment (which has reference semantics) to store the data.frame so it will not be copied on return.

Here is a test of all the methods for both small and large number of appended rows. Each method has 3 functions associated with it:

• create(first_element) that returns the appropriate backing object with first_element put in.

• append(object, element) that appends the element to the end of the table (represented by object).

• access(object) gets the data.frame with all the inserted elements.

rbindlist to the data.frame

That is quite easy and straight-forward:

create.1<-function(elems)
{
  return(as.data.table(elems))
}

append.1<-function(dt, elems)
{ 
  return(rbindlist(list(dt,  elems),use.names = TRUE))
}

access.1<-function(dt)
{
  return(dt)
}

data.table::set + manually doubling the table when needed.

I will store the true length of the table in a rowcount attribute.

create.2<-function(elems)
{
  return(as.data.table(elems))
}

append.2<-function(dt, elems)
{
  n<-attr(dt, 'rowcount')
  if (is.null(n))
    n<-nrow(dt)
  if (n==nrow(dt))
  {
    tmp<-elems[1]
    tmp[[1]]<-rep(NA,n)
    dt<-rbindlist(list(dt, tmp), fill=TRUE, use.names=TRUE)
    setattr(dt,'rowcount', n)
  }
  pos<-as.integer(match(names(elems), colnames(dt)))
  for (j in seq_along(pos))
  {
    set(dt, i=as.integer(n+1), pos[[j]], elems[[j]])
  }
  setattr(dt,'rowcount',n+1)
  return(dt)
}

access.2<-function(elems)
{
  n<-attr(elems, 'rowcount')
  return(as.data.table(elems[1:n,]))
}

SQL should be optimized for fast record insertion, so I initially had high hopes for RSQLite solution

This is basically copy&paste of Karsten W. answer on similar thread.

create.3<-function(elems)
{
  con <- RSQLite::dbConnect(RSQLite::SQLite(), ":memory:")
  RSQLite::dbWriteTable(con, 't', as.data.frame(elems))
  return(con)
}

append.3<-function(con, elems)
{ 
  RSQLite::dbWriteTable(con, 't', as.data.frame(elems), append=TRUE)
  return(con)
}

access.3<-function(con)
{
  return(RSQLite::dbReadTable(con, "t", row.names=NULL))
}

data.frame's own row-appending + custom environment.

create.4<-function(elems)
{
  env<-new.env()
  env$dt<-as.data.frame(elems)
  return(env)
}

append.4<-function(env, elems)
{ 
  env$dt[nrow(env$dt)+1,]<-elems
  return(env)
}

access.4<-function(env)
{
  return(env$dt)
}

The test suite:

For convenience I will use one test function to cover them all with indirect calling. (I checked: using do.call instead of calling the functions directly doesn't makes the code run measurable longer).

test<-function(id, n=1000)
{
  n<-n-1
  el<-list(a=1,b=2,c=3,d=4)
  o<-do.call(paste0('create.',id),list(el))
  s<-paste0('append.',id)
  for (i in 1:n)
  {
    o<-do.call(s,list(o,el))
  }
  return(do.call(paste0('access.', id), list(o)))
}

Let's see the performance for n=10 insertions.

I also added a 'placebo' functions (with suffix 0) that don't perform anything - just to measure the overhead of the test setup.

r<-microbenchmark(test(0,n=10), test(1,n=10),test(2,n=10),test(3,n=10), test(4,n=10))
autoplot(r)

For 1E5 rows (measurements done on Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz):

nr  function      time
4   data.frame    228.251 
3   sqlite        133.716
2   data.table      3.059
1   rbindlist     169.998 
0   placebo         0.202

It looks like the SQLite-based sulution, although regains some speed on large data, is nowhere near data.table + manual exponential growth. The difference is almost two orders of magnitude!

Summary

If you know that you will append rather small number of rows (n<=100), go ahead and use the simplest possible solution: just assign the rows to the data.frame using bracket notation and ignore the fact that the data.frame is not pre-populated.

For everything else use data.table::set and grow the data.table exponentially (e.g. using my code).

remove(int index) method of arraylist removes the element at the specified position(index) in the list. After removing arraylist items shifts any subsequent elements to the left.

Means if a arraylist contains {20,15,30,40}

I have called the method: arraylist.remove(1)

then the data 15 will be deleted and 30 & 40 these two items will be left shifted by 1.

For this reason you have to delete higher index item of arraylist first.

So..for your given situation..the code will be..

ArrayList<String> list = new ArrayList<String>();
list.add("A");
list.add("B");
list.add("C");
list.add("D");
list.add("E");
list.add("F");
list.add("G");
list.add("H");

int i[] = {1,3,5};

for (int j = i.length-1; j >= 0; j--) {
    list.remove(i[j]);
}

Single Threaded Event Loop Model Processing Steps:

• Clients Send request to Web Server.

• Node JS Web Server internally maintains a Limited Thread pool to provide services to the Client Requests.

• Node JS Web Server receives those requests and places them into a Queue. It is known as “Event Queue”.

• Node JS Web Server internally has a Component, known as “Event Loop”. Why it got this name is that it uses indefinite loop to receive requests and process them.

• Event Loop uses Single Thread only. It is main heart of Node JS Platform Processing Model.

• Event Loop checks any Client Request is placed in Event Queue. If not then wait for incoming requests for indefinitely.

• If yes, then pick up one Client Request from Event Queue

  1. Starts process that Client Request
  2. If that Client Request Does Not requires any Blocking IO Operations, then process everything, prepare response and send it back to client.
  3. If that Client Request requires some Blocking IO Operations like interacting with Database, File System, External Services then it will follow different approach
• Checks Threads availability from Internal Thread Pool
• Picks up one Thread and assign this Client Request to that thread.

• That Thread is responsible for taking that request, process it, perform Blocking IO operations, prepare response and send it back to the Event Loop

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

Here is a function that will flatten an object or array. Use this only if you are sure your keys are unique. If you have keys with the same name they will be overwritten. You will need to place this in a class and replace "Functions" with the name of your class. Enjoy...

function flatten($array, $preserve_keys=1, &$out = array(), $isobject=0) {
        # Flatten a multidimensional array to one dimension, optionally preserving keys.
        #
        # $array - the array to flatten
        # $preserve_keys - 0 (default) to not preserve keys, 1 to preserve string keys only, 2 to preserve all keys
        # $out - internal use argument for recursion
        # $isobject - is internally set in order to remember if we're using an object or array
        if(is_array($array) || $isobject==1)
        foreach($array as $key => $child)
            if(is_array($child))
                $out = Functions::flatten($child, $preserve_keys, $out, 1); // replace "Functions" with the name of your class
            elseif($preserve_keys + is_string($key) > 1)
                $out[$key] = $child;
            else
                $out[] = $child;

        if(is_object($array) || $isobject==2)
        if(!is_object($out)){$out = new stdClass();}
        foreach($array as $key => $child)
            if(is_object($child))
                $out = Functions::flatten($child, $preserve_keys, $out, 2); // replace "Functions" with the name of your class
            elseif($preserve_keys + is_string($key) > 1)
                $out->$key = $child;
            else
                $out = $child;

        return $out;
}

I found this post to contain the simplest answer. Merely do:

git checkout <branch from which you want files> <file paths>

Example

Pulling .gitignore file from branchB into current branch:

git checkout branchB .gitignore

See the post for more information.

Try using FIND_IN_SET() function of MySql e.g.

SET @c = 'xxx,yyy,zzz';

SELECT * from countries 
WHERE FIND_IN_SET(countryname,@c);

Note: You don't have to SET variable in StoredProcedure if you are passing parameter with CSV values.

It seems that most of the answers missed the original question.

Is there a standard sign function (signum, sgn) in C/C++?

Not in the standard library, however there is copysign which can be used almost the same way via copysign(1.0, arg) and there is a true sign function in boost, which might as well be part of the standard.

    #include <boost/math/special_functions/sign.hpp>

    //Returns 1 if x > 0, -1 if x < 0, and 0 if x is zero.
    template <class T>
    inline int sign (const T& z);

http://www.boost.org/doc/libs/1_47_0/libs/math/doc/sf_and_dist/html/math_toolkit/utils/sign_functions.html

You could make use of the Javascript DOM API. In particular, look at the createElement() method.

You could create a re-usable function that will create an image like so...

function show_image(src, width, height, alt) {
    var img = document.createElement("img");
    img.src = src;
    img.width = width;
    img.height = height;
    img.alt = alt;

    // This next line will just add it to the <body> tag
    document.body.appendChild(img);
}

Then you could use it like this...

<button onclick=
    "show_image('http://google.com/images/logo.gif', 
                 276, 
                 110, 
                 'Google Logo');">Add Google Logo</button> 

See a working example on jsFiddle: http://jsfiddle.net/Bc6Et/

i think doing some like this.

void printchar(char c, int n){
     int i;
     for(i=0;i<n;i++)
         print("%c",c);
}

printchar("*",10);

Set the following system properties, this will enabled xml logging. You can set it in java or configuration file.

static{
        System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");
        System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dumpTreshold", "999999");
    }

Filezilla just released a Pro version of their FTP client. It connects to S3 buckets in a streamlined FTP like experience. I use it myself (no affiliation whatsoever) and it works great.

I'd add, that you can also use this to call multiple emits or methods or both together by separating with ; semicolon

  @click="method1(); $emit('emit1'); $emit('emit2');"

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

The simplest solution that worked for me was to put a height constraint on the textView in the Storyboard, then connect the textView and height constraint to the code:

@IBOutlet var myAwesomeTextView: UITextView!
@IBOutlet var myAwesomeTextViewHeight: NSLayoutConstraint!

Then after setting the text and paragraph styles, add this in viewDidAppear:

self.myAwesomeTextViewHeight.constant = self.myAwesomeTextView.contentSize.height

Some notes:

1. In contrast to other solutions, isScrollEnabled must to be set to true in order for this to work.
2. In my case, I was setting custom attributes to the font inside the code, therefore I had to set the height in viewDidAppear (it wouldn't work properly before that). If you aren't changing any text attributes in code, you should be able to set the height in viewDidLoad or anywhere after setting the text.

Try .replace(/ /g,"_");

Edit: or .split(' ').join('_') if you have an aversion to REs

Edit: John Resig said:

If you're searching and replacing through a string with a static search and a static replace it's faster to perform the action with .split("match").join("replace") - which seems counter-intuitive but it manages to work that way in most modern browsers. (There are changes going in place to grossly improve the performance of .replace(/match/g, "replace") in the next version of Firefox - so the previous statement won't be the case for long.)

Use ArrayList.set

You can see here http://msdn.microsoft.com/en-us/library/system.iformatprovider.aspx

See the remarks and example section there.

This is fixed in npm 7. See npm/cli#PR169

If you need a drive letter (some applications don't like UNC style paths that start with a machine-name) you can "map a drive" to a UNC path. Right-click on "My Computer" and select Map Network Drive... or use this command line:

NET USE z: \server\c$\folder1\folder2

NET USE y: \server\d$

Note that you can map drive-to-drive or drill down and map to sub-folder.

Something like this:

select * 
from User U1
where time_stamp = (
  select max(time_stamp) 
  from User 
  where username = U1.username)

should do it.

I like Fernandes' answer even though you ask for the obj twice.

This should also do (more or less the same as Martin's A).

id obj;

if ((obj=[dict objectForKey:@"blah"])) {
   // use obj
} else {
   // Do something else like creating the obj and add the kv pair to the dict
}

Martin's and this answer both work on iPad2 iOS 5.0.1 9A405

This is your code: http://jsfiddle.net/WSFnX/

Using display: table-cell is fine, provided that you're aware that it won't work in IE6/7. Other than that, it's safe: Is there a disadvantage of using `display:table-cell`on divs?

To fix the space at the bottom, add vertical-align: bottom to the actual imgs:

http://jsfiddle.net/WSFnX/1/

Removing the space between the images boils down to this: bikeshedding CSS3 property alternative?

So, here's a demo with the whitespace removed in your HTML: http://jsfiddle.net/WSFnX/4/

- file:
    path: /etc/some_directory
    state: directory
    mode: 0755
    owner: someone
    group: somegroup

That's the way you can actually also set the permissions, the owner and the group. The last three parameters are not obligatory.

ip addr show | grep -E '^\s*inet' | grep -m1 global | awk '{ print $2 }' | sed 's|/.*||'

One more cause for this:

If the routes are overridden with the same URI (Unknowingly), it causes this error:

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('dashboard/', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']);

In this case route 'my.dashboard' is invalidate as the both routes has same URI ('dashboard', 'dashboard/')

Solution: You should change the URI for either one

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('home-dashboard', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']); 

// See the URI changed for this 'home-dashboard'

Hope it helps some once.

Actually it is rather easy. Just think for the optimal way. I beleive the optimal way is:

for (int i=0; i<list.size(); i++) {
   Level obj = list.get(i);

   //Here execute yr code that may add / or may not add new element(s)
   //...

   i=list.indexOf(obj);
}

The following example works perfectly in the most logical case - when you dont need to iterate the added new elements before the iteration element. About the added elements after the iteration element - there you might want not to iterate them either. In this case you should simply add/or extend yr object with a flag that will mark them not to iterate them.

str.matches(regex) behaves like Pattern.matches(regex, str) which attempts to match the entire input sequence against the pattern and returns

true if, and only if, the entire input sequence matches this matcher's pattern

Whereas matcher.find() attempts to find the next subsequence of the input sequence that matches the pattern and returns

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

Thus the problem is with the regex. Try the following.

String test = "User Comments: This is \t a\ta \ntest\n\n message \n";

String pattern1 = "User Comments: [\\s\\S]*^test$[\\s\\S]*";
Pattern p = Pattern.compile(pattern1, Pattern.MULTILINE);
System.out.println(p.matcher(test).find());  //true

String pattern2 = "(?m)User Comments: [\\s\\S]*^test$[\\s\\S]*";
System.out.println(test.matches(pattern2));  //true

Thus in short, the (\\W)*(\\S)* portion in your first regex matches an empty string as * means zero or more occurrences and the real matched string is User Comments: and not the whole string as you'd expect. The second one fails as it tries to match the whole string but it can't as \\W matches a non word character, ie [^a-zA-Z0-9_] and the first character is T, a word character.

i just do :

set /p input= yes or no
if %input%==yes echo you clicked yes
if %input%==no echo you clicked no
pause

Prefixing the statement with an exclamation mark will let you know whether the array is not empty. So in your case -

a = [1,2,3]
!a.empty?
=> true

In Python 3, I find pathlib is the easiest way to do this. Request's response.content marries up nicely with pathlib's write_bytes.

from pathlib import Path
import requests
filename = Path('metadata.pdf')
url = 'http://www.hrecos.org//images/Data/forweb/HRTVBSH.Metadata.pdf'
response = requests.get(url)
filename.write_bytes(response.content)

I was getting the same error Requires: container-selinux >= 2.9 on amazon ec2 instance(Rhel7)

I tried to add extra package rmp repo by executing sudo yum-config-manager --enable rhui-REGION-rhel-server-extras
but it works. followed steps from https://installdocker.blogspot.com/ and I was able to install docker.

Here are 3 examples:

I solved this problem with conda and pip.

Firstly, I run:

conda uninstall qt and conda uninstall matplotlib and conda uninstall PyQt5

After that, I opened the cmd and run this code that

pip uninstall qt , pip uninstall matplotlib , pip uninstall PyQt5

Lastly, You should install matplotlib in pip by this code that pip install matplotlib

You can use zip:

>>> a = [1, 2, 3]
>>> b = ['a', 'b', 'c']
>>> for x, y in zip(a, b):
...   print x, y
... 
1 a
2 b
3 c

I'm giving this example because this actually work for my use case.

I was trying to use the AWS Rekognition API. The API returns a BoundingBox object:

BoundingBox boundingBox = faceDetail.getBoundingBox();

The code below uses it to crop the image:

import com.amazonaws.services.rekognition.model.BoundingBox;

private BufferedImage cropImage(BufferedImage image, BoundingBox box) {
        Rectangle goal = new Rectangle(Math.round(box.getLeft()* image.getWidth()),Math.round(box.getTop()* image.getHeight()),Math.round(box.getWidth() * image.getWidth()), Math.round(box.getHeight() * image.getHeight()));

        Rectangle clip = goal.intersection(new Rectangle(image.getWidth(), image.getHeight()));

        BufferedImage clippedImg = image.getSubimage(clip.x, clip.y , clip.width, clip.height);

        return clippedImg;
    }

REST is a software design pattern typically used for web applications. In layman's terms this means that it is a commonly used idea used in many different projects. It stands for REpresentational State Transfer. The basic idea of REST is treating objects on the server-side (as in rows in a database table) as resources than can be created or destroyed.

The most basic way of thinking about REST is as a way of formatting the URLs of your web applications. For example, if your resource was called "posts", then:

/posts Would be how a user would access ALL the posts, for displaying.

/posts/:id Would be how a user would access and view an individual post, retrieved based on their unique id.

/posts/new Would be how you would display a form for creating a new post.

Sending a POST request to /users would be how you would actually create a new post on the database level.

Sending a PUT request to /users/:id would be how you would update the attributes of a given post, again identified by a unique id.

Sending a DELETE request to /users/:id would be how you would delete a given post, again identified by a unique id.

As I understand it, the REST pattern was mainly popularized (for web apps) by the Ruby on Rails framework, which puts a big emphasis on RESTful routes. I could be wrong about that though.

I may not be the most qualified to talk about it, but this is how I've learned it (specifically for Rails development).

When someone refers to a "REST api," generally what they mean is an api that uses RESTful urls for retrieving data.

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

According to Apple, generally disabling ATS will lead to app rejection, unless you have a good reason to do so. Even then, you should add exceptions for domains that you can access safely.

Apple has an excellent tool that tells you exactly what settings to use: In Terminal, enter

/usr/bin/nscurl --ats-diagnostics --verbose https://www.example.com/whatever

and nscurl will check whether this request fails, and then try a variety of settings and tell you exactly which one passes, and what to do. For example, for some third-party URL that I visit, this command told me that this dictionary passes:

{
    NSExceptionDomains = {
        "www.example.com" = {
            NSExceptionRequiresForwardSecrecy = false;
        };
    };
}

To distinguish between your own sites and third-party sites that are out of your control, use, for example, the key NSThirdPartyExceptionRequiresForwardSecrecy.

double[,] is a 2d array (matrix) while double[][] is an array of arrays (jagged arrays) and the syntax is:

double[][] ServicePoint = new double[10][];

@JigarJoshi it's the good answer, and of course also @Tim recommendation to use .joda-time.

I only want to add more possibilities to subtract days from a java.util.Date.

Apache-commons

One possibility is to use apache-commons-lang. You can do it using DateUtils as follows:

Date dateBefore30Days = DateUtils.addDays(new Date(),-30);

Of course add the commons-lang dependency to do only date subtract it's probably not a good options, however if you're already using commons-lang it's a good choice. There is also convenient methods to addYears,addMonths,addWeeks and so on, take a look at the api here.

Java 8

Another possibility is to take advantage of new LocalDate from Java 8 using minusDays(long days) method:

LocalDate dateBefore30Days = LocalDate.now(ZoneId.of("Europe/Paris")).minusDays(30);

(int) add: (int) numberOne plus: (int) numberTwo ;
(returnType) functionPrimaryName : (returnTypeOfArgumentOne) argumentName functionSecondaryNa

me:

(returnTypeOfSecontArgument) secondArgumentName ;

as in other languages we use following syntax void add(int one, int second) but way of assigning arguments in OBJ_c is different as described above

Use. <?php $con = mysqli_connect('localhost', 'username', 'password', 'database'); ?>

In PHP 7. You probably have PHP 7 in XAMPP. You now have two option: MySQLi and PDO.

I had the same problem and I fixed it with:

<div id="container" style="width: 100%; height: 100%; position:absolute"></div>

The chart fits perfect to the browser even if I resize it. You can change the percentage according to your needs.

in the Gradle 5.1.1 version on mac ive changed how the task names got retrieved, i althought tried to get build flavour / type from build but was to lazy to split the task name:

def versionPropsFile = file('version.properties')
if (versionPropsFile.canRead()) {
    def Properties versionProps = new Properties()

    versionProps.load(new FileInputStream(versionPropsFile))

    def value = 0

    def runTasks = gradle.getStartParameter().getTaskRequests().toString()

    if (runTasks.contains('assemble') || runTasks.contains('assembleRelease') || runTasks.contains('aR')) {
        value = 1
    }

    def versionMajor = 1
    def versionMinor = 0
    def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
    def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
    def versionNumber = versionProps['VERSION_NUMBER'].toInteger() + value

    versionProps['VERSION_PATCH'] = versionPatch.toString()
    versionProps['VERSION_BUILD'] = versionBuild.toString()
    versionProps['VERSION_NUMBER'] = versionNumber.toString()

    versionProps.store(versionPropsFile.newWriter(), null)

    defaultConfig {
        applicationId "de.evomotion.ms10"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode versionNumber
        versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild})"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        signingConfig signingConfigs.debug
    }

} else {
    throw new GradleException("Could not read version.properties!")
}

If you have the Windows SDK installed on your machine, you'll find the "Fusion Log Viewer" under Microsoft SDK\Tools (just type "Fusion" in the start menu on Vista or Windows 7/8). Launch it, click the Settings button, and select "Log bind failure" or "Log all binds".

If these buttons are disabled, go back to the start menu, right-click the Log Viewer, and select "Run as Administrator".

The problem was actually in the version Android Studio 1.3 updated from the canary channel. I updated my studio to 1.3 and got the same error but reverting back to studio 1.2.1 made my project run fine.

In phpMyAdmin, click the table, and then click the Import tab at the top of the page.

Browse and open the csv file. Leave the charset as-is. Uncheck partial import unless you have a HUGE dataset (or slow server). The format should already have selected “CSV” after selecting your file, if not then select it (not using LOAD DATA). If you want to clear the whole table before importing, check “Replace table data with file”. Optionally check “Ignore duplicate rows” if you think you have duplicates in the CSV file. Now the important part, set the next four fields to these values:

Fields terminated by: ,
Fields enclosed by: “
Fields escaped by: \
Lines terminated by: auto

Currently these match the defaults except for “Fields terminated by”, which defaults to a semicolon.

Now click the Go button, and it should run successfully.

or_() function can be useful in case of unknown number of OR query components.

For example, let's assume that we are creating a REST service with few optional filters, that should return record if any of filters return true. On the other side, if parameter was not defined in a request, our query shouldn't change. Without or_() function we must do something like this:

query = Book.query
if filter.title and filter.author:
    query = query.filter((Book.title.ilike(filter.title))|(Book.author.ilike(filter.author)))
else if filter.title:
    query = query.filter(Book.title.ilike(filter.title))
else if filter.author:
    query = query.filter(Book.author.ilike(filter.author))

With or_() function it can be rewritten to:

query = Book.query
not_null_filters = []
if filter.title:
    not_null_filters.append(Book.title.ilike(filter.title))
if filter.author:
    not_null_filters.append(Book.author.ilike(filter.author))

if len(not_null_filters) > 0:
    query = query.filter(or_(*not_null_filters))

   MyFragment fragment = (MyFragment) getSupportFragmentManager().findFragmentByTag(FRAGMENT_TAG);
        getSupportFragmentManager().beginTransaction().detach(fragment).attach(fragment).commit();

this will only work if u use FragmentManager to initialize the fragment. If u have it as a <fragment ... /> in XML, it won't call the onCreateView again. Wasted my 30 minutes to figure this out.

puts 'abcdefg'.start_with?('abc')  #=> true

[edit] This is something I didn't know before this question: start_with takes multiple arguments.

'abcdefg'.start_with?( 'xyz', 'opq', 'ab')

The correct answer is as @JaKu pointed out. Tomcat is confining the access to localhost to make it secure. This is as it should be. Port forwarding to tomcat is the correct thing to do, preferably under something secure like SSH.

FILE *f = fopen("file.txt", "w");
if (f == NULL)
{
    printf("Error opening file!\n");
    exit(1);
}

/* print some text */
const char *text = "Write this to the file";
fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

fclose(f);

I see a lot of good answers here, but none that directly address the lack of a StringStream class in C#. So I have written one of my own...

public class StringStream : Stream
{
    private readonly MemoryStream _memory;
    public StringStream(string text)
    {
        _memory = new MemoryStream(Encoding.UTF8.GetBytes(text));
    }
    public StringStream()
    {
        _memory = new MemoryStream();
    }
    public StringStream(int capacity)
    {
        _memory = new MemoryStream(capacity);
    }
    public override void Flush()
    {
        _memory.Flush();
    }
    public override int Read(byte[] buffer, int offset, int count)
    {
        return  _memory.Read(buffer, offset, count);
    }
    public override long Seek(long offset, SeekOrigin origin)
    {
        return _memory.Seek(offset, origin);
    }
    public override void SetLength(long value)
    {
        _memory.SetLength(value);
    }
    public override void Write(byte[] buffer, int offset, int count)
    {
        _memory.Write(buffer, offset, count);
        return;
    }
    public override bool CanRead => _memory.CanRead;
    public override bool CanSeek => _memory.CanSeek;
    public override bool CanWrite => _memory.CanWrite;
    public override long Length =>  _memory.Length;
    public override long Position
    {
        get => _memory.Position;
        set => _memory.Position = value;
    }
    public override string ToString()
    {
        return System.Text.Encoding.UTF8.GetString(_memory.GetBuffer(), 0, (int) _memory.Length);
    }
    public override int ReadByte()
    {
        return _memory.ReadByte();
    }
    public override void WriteByte(byte value)
    {
        _memory.WriteByte(value);
    }
}

An example of its use...

        string s0 =
            "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor\r\n" +
            "incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud\r\n" +

            "occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.\r\n";
        StringStream ss0 = new StringStream(s0);
        StringStream ss1 = new StringStream();
        int line = 1;
        Console.WriteLine("Contents of input stream: ");
        Console.WriteLine();
        using (StreamReader reader = new StreamReader(ss0))
        {
            using (StreamWriter writer = new StreamWriter(ss1))
            {
                while (!reader.EndOfStream)
                {
                    string s = reader.ReadLine();
                    Console.WriteLine("Line " + line++ + ": " + s);
                    writer.WriteLine(s);
                }
            }
        }

        Console.WriteLine();
        Console.WriteLine("Contents of output stream: ");
        Console.WriteLine();
        Console.Write(ss1.ToString());
