Here is How I close my alertDialog

lv_three.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                GetTalebeDataUser clickedObj = (GetTalebeDataUser) parent.getItemAtPosition(position);
                alertDialog.setTitle(clickedObj.getAd());
                alertDialog.setMessage("Ögrenci Bilgileri Güncelle?");
                alertDialog.setIcon(R.drawable.ic_info);
                // Setting Positive "Yes" Button
                alertDialog.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // User pressed YES button. Write Logic Here
                    }
                });
                alertDialog.setNegativeButton("Iptal", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        //alertDialog.
                        alertDialog.setCancelable(true); // HERE

                    }
                });
                alertDialog.show();
                return true;
            }
        });

As you can see here there is a very simple way to do that.

In your DialogFragment add an interface listener like:

public interface EditNameDialogListener {
    void onFinishEditDialog(String inputText);
}

Then, add a reference to that listener:

private EditNameDialogListener listener;

This will be used to "activate" the listener method(s), and also to check if the parent Activity/Fragment implements this interface (see below).

In the Activity/FragmentActivity/Fragment that "called" the DialogFragment simply implement this interface.

In your DialogFragment all you need to add at the point where you'd like to dismiss the DialogFragment and return the result is this:

listener.onFinishEditDialog(mEditText.getText().toString());
this.dismiss();

Where mEditText.getText().toString() is what will be passed back to the calling Activity.

Note that if you want to return something else simply change the arguments the listener takes.

Finally, you should check whether the interface was actually implemented by the parent activity/fragment:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    // Verify that the host activity implements the callback interface
    try {
        // Instantiate the EditNameDialogListener so we can send events to the host
        listener = (EditNameDialogListener) context;
    } catch (ClassCastException e) {
        // The activity doesn't implement the interface, throw exception
        throw new ClassCastException(context.toString()
                + " must implement EditNameDialogListener");
    }
}

This technique is very flexible and allow calling back with the result even if your don;t want to dismiss the dialog just yet.

In Java Class:

    public class EnumTest{
    //Other property link
    private String name;
    ....

        public enum Status {
                ACTIVE,NEWLINK, BROADCASTED, PENDING, CLICKED, VERIFIED, AWARDED, INACTIVE, EXPIRED, DELETED_BY_ADMIN;
            }

        private Status statusobj ;

    //Getter and Setters
}

So now POJO and enum obj is created. Now EnumTest you will set in session object using in the servlet or controller class session.setAttribute("enumTest", EnumTest );

In JSP Page

<c:if test="${enumTest.statusobj == 'ACTIVE'}">

//TRUE??? THEN PROCESS SOME LOGIC

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write which divrat and see what will be the result. If it returns path of the function and the comment Has no license available, then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original matlab. Please check and solve the license issue, then it will work fine.

$computer,$Speed,$Regcheck will create an array, and run out-file ones per variable = they get seperate lines. If you construct a single string using the variables first, it will show up a single line. Like this:

"$computer,$Speed,$Regcheck" | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

Technical Note TN2265: Troubleshooting Push Notifications

The first time a push-enabled app registers for push notifications, iOS asks the user if they wish to receive notifications for that app. Once the user has responded to this alert it is not presented again unless the device is restored or the app has been uninstalled for at least a day.

If you want to simulate a first-time run of your app, you can leave the app uninstalled for a day. You can achieve the latter without actually waiting a day by setting the system clock forward a day or more, turning the device off completely, then turning the device back on.

Update: As noted in the comments below, this solution stopped working since iOS 5.1. I would encourage filing a bug with Apple so they can update their documentation. The current solution seems to be resetting the device's content and settings.

Update: The tech note has been updated with new steps that work correctly as of iOS 7.

1. Delete your app from the device.
2. Turn the device off completely and turn it back on.
3. Go to Settings > General > Date & Time and set the date ahead a day or more.
4. Turn the device off completely again and turn it back on.

UPDATE as of iOS 9

Simply deleting and reinstalling the app will reset the notification status to notDetermined (meaning prompts will appear).

I believe pwdencrypt is using a hash so you cannot really reverse the hashed string - the algorithm is designed so it's impossible.

If you are verifying the password that a user entered the usual technique is to hash it and then compare it to the hashed version in the database.

This is how you could verify a usered entered table

SELECT password_field FROM mytable WHERE password_field=pwdencrypt(userEnteredValue)

Replace userEnteredValue with (big surprise) the value that the user entered :)

It may make things more elegant to wrap it in a property.

string MySessionVar
{
   get{
      return Session["MySessionVar"] ?? String.Empty;
   }
   set{
      Session["MySessionVar"] = value;
   }
}

then you can treat it as a string.

if( String.IsNullOrEmpty( MySessionVar ) )
{
   // do something
}

You are trying to join Person_Fear.PersonID onto Person_Fear.FearID - This doesn't really make sense. You probably want something like:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear
    INNER JOIN Fears
    ON Person_Fear.FearID = Fears.FearID
ON Person_Fear.PersonID = Persons.PersonID

This joins Persons onto Fears via the intermediate table Person_Fear. Because the join between Persons and Person_Fear is a LEFT JOIN, you will get all Persons records.

Alternatively:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear ON Person_Fear.PersonID = Persons.PersonID
LEFT JOIN Fears ON Person_Fear.FearID = Fears.FearID

The simplest solution is:

git clone --recursive [email protected]:name/repo.git

Then cd in the repo directory and:

git submodule update --init
git submodule foreach -q --recursive 'git checkout $(git config -f $toplevel/.gitmodules submodule.$name.branch || echo master)'
git config --global status.submoduleSummary true

Very sort cut and effective solution is below:-

Add the below rule in your tsconfig.json file:-

"noImplicitAny": false

Then restart your project.

if yo want to place in an div like i have same work and i do it like

<div id="content>
<?php
while($row = mysql_fetch_array($result))
{
echo '<img src="'.$row['name'].'" />';  
echo "<div>".$row['name']."</div>";
echo "<div>".$row['title']."</div>";
echo "<div>".$row['description']."</div>";
echo "<div>".$row['link']."</div>";
echo "<br />";

Chrome does not allow autoplay if the video is not muted. Try using this:

<video width="440px" loop="true" autoplay="autoplay" controls muted>
  <source src="http://www.tuscorlloyds.com/CorporateVideo.mp4" type="video/mp4" />
  <source src="http://www.tuscorlloyds.com/CorporateVideo.ogv" type="video/ogv" />

All you have to do is to remove the table row (<tr>) tag from your table. For example here is the code to remove the last row from the table:

$('#myTable tr:last').remove();

*Code above was taken from this jQuery Howto post.

If you're just checking if word is a number, that's not too hard:

#include <ctype.h>

...

string word;
bool isNumber = true;
for(string::const_iterator k = word.begin(); k != word.end(); ++k)
    isNumber &&= isdigit(*k);

Optimize as desired.

So here is the controller code.

public IActionResult AddURLTest()
{
    return ViewComponent("AddURL");
}

You can load it using JQuery load method.

$(document).ready (function(){
    $("#LoadSignIn").click(function(){
        $('#UserControl').load("/Home/AddURLTest");
    });
});

UPDATED

I have take comments below into consideration and agreed. Eval is to be avoided.

Accessing root properties in object is easily achieved with obj[variable], but getting nested complicates thing. Not to write already written code I suggest to use lodash.get.

Example

// Accessing root property
var rootProp = 'rootPropert';
_.get(object, rootProp, defaultValue);

// Accessing nested property
var listOfNestedProperties = [var1, var2];
_.get(object, listOfNestedProperties);

Lodash get can be used on different ways, here is link to the documentation lodash.get

I've loved weinre! How to use it:

First, put on your index.html (ensure app.settings.debugUrl is set before this):

  <!-- Weinre debugging -->
  <script type="text/javascript">
    if (app.settings.debugUrl) {
      document.addEventListener("DOMContentLoaded", function(event) { 
        var s = document.createElement("script")
        s.setAttribute("src", app.settings.debugUrl+"/target/target-script-min.js#anonymous")
        document.getElementsByTagName("body")[0].appendChild(s)
      }); 
    }   
  </script>

Then:

• install: sudo npm install -g weinre
• run: weinre --boundHost -all-
• open on browser: http://localhost:8080/client/#anonymous
• watch targets appear as you open the app

Based on http://www.broken-links.com/2013/06/28/remote-debugging-with-weinre/

In Express 4.x I used the following to load ejs:

  var path = require('path');

  // Set the default templating engine to ejs
  app.set('view engine', 'ejs');
  app.set('views', path.join(__dirname, 'views'));

  // The views/index.ejs exists in the app directory
  app.get('/hello', function (req, res) {
    res.render('index', {title: 'title'});
  });

Then you just need two files to make it work - views/index.ejs:

<%- include partials/navigation.ejs %>

And the views/partials/navigation.ejs:

<ul><li class="active">...</li>...</ul>

You can also tell Express to use ejs for html templates:

var path = require('path');
var EJS  = require('ejs');

app.engine('html', EJS.renderFile);

// Set the default templating engine to ejs
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));

// The views/index.html exists in the app directory
app.get('/hello', function (req, res) {
  res.render('index.html', {title: 'title'});
});

Finally you can also use the ejs layout module:

var EJSLayout = require('express-ejs-layouts');
app.use(EJSLayout);

This will use the views/layout.ejs as your layout.

The best solution is a minimal use of java directly in the visualstudio GUI

here it is: On a button go to the "OnClientClick" property (its not into events*) overthere type:

return confirm('are you sure?')

it will put a dialog with cancel ok buttons transparent over current page if cancel is pressed no postback will ocure. However if you want only ok button type:

alert ('i told you so')

The events like onclick work server side they execute your code, while OnClientClick runs in the browser side. the come most close to a basic dialog

I prefer onKeyUp since it only fires when the key is released. onKeyDown, on the other hand, will fire multiple times if for some reason the user presses and holds the key. For example, when listening for "pressing" the Enter key to make a network request, you don't want that to fire multiple times since it can be expensive.

// handler could be passed as a prop
<input type="text" onKeyUp={handleKeyPress} />

handleKeyPress(e) {
if (e.key === 'Enter') {
  // do whatever
}

}

Also, stay away from keyCode since it will be deprecated some time.

if you need to return an array elements with same value, use array_keys() function

$array = array('red' => 1, 'blue' => 1, 'green' => 2);
print_r(array_keys($array, 1));

If you don't mind a crass writing style, Redis vs Memcached on the Systoilet blog is worth a read from a usability standpoint, but be sure to read the back & forth in the comments before drawing any conclusions on performance; there are some methodological problems (single-threaded busy-loop tests), and Redis has made some improvements since the article was written as well.

And no benchmark link is complete without confusing things a bit, so also check out some conflicting benchmarks at Dormondo's LiveJournal and the Antirez Weblog.

Edit -- as Antirez points out, the Systoilet analysis is rather ill-conceived. Even beyond the single-threading shortfall, much of the performance disparity in those benchmarks can be attributed to the client libraries rather than server throughput. The benchmarks at the Antirez Weblog do indeed present a much more apples-to-apples (with the same mouth) comparison.

What about using the ×-mark (the multiplication symbol), × in HTML, for that?

"x" (letter) should not be used to represent anything else other than the letter X.

if you have multiple parameters use the syntax as below. I have a bat file with script as below:

start "dummyTitle" [/options] D:\path\ProgramName.exe Param1 Param2 Param3 
start "dummyTitle" [/options] D:\path\ProgramName.exe Param4 Param5 Param6 

This will open multiple consoles.

Unlike others I think there are many reasons why you might always want the latest version. Particularly if you are doing continuous deployment (we sometimes have like 5 releases in a day) and don't want to do a multi-module project.

What I do is make Hudson/Jenkins do the following for every build:

mvn clean versions:use-latest-versions scm:checkin deploy -Dmessage="update versions" -DperformRelease=true

That is I use the versions plugin and scm plugin to update the dependencies and then check it in to source control. Yes I let my CI do SCM checkins (which you have to do anyway for the maven release plugin).

You'll want to setup the versions plugin to only update what you want:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>versions-maven-plugin</artifactId>
    <version>1.2</version>
    <configuration>
        <includesList>com.snaphop</includesList>
        <generateBackupPoms>false</generateBackupPoms>
        <allowSnapshots>true</allowSnapshots>
    </configuration>
</plugin>

I use the release plugin to do the release which takes care of -SNAPSHOT and validates that there is a release version of -SNAPSHOT (which is important).

If you do what I do you will get the latest version for all snapshot builds and the latest release version for release builds. Your builds will also be reproducible.

Update

I noticed some comments asking some specifics of this workflow. I will say we don't use this method anymore and the big reason why is the maven versions plugin is buggy and in general is inherently flawed.

It is flawed because to run the versions plugin to adjust versions all the existing versions need to exist for the pom to run correctly. That is the versions plugin cannot update to the latest version of anything if it can't find the version referenced in the pom. This is actually rather annoying as we often cleanup old versions for disk space reasons.

Really you need a separate tool from maven to adjust the versions (so you don't depend on the pom file to run correctly). I have written such a tool in the the lowly language that is Bash. The script will update the versions like the version plugin and check the pom back into source control. It also runs like 100x faster than the mvn versions plugin. Unfortunately it isn't written in a manner for public usage but if people are interested I could make it so and put it in a gist or github.

Going back to workflow as some comments asked about that this is what we do:

1. We have 20 or so projects in their own repositories with their own jenkins jobs
2. When we release the maven release plugin is used. The workflow of that is covered in the plugin's documentation. The maven release plugin sort of sucks (and I'm being kind) but it does work. One day we plan on replacing this method with something more optimal.
3. When one of the projects gets released jenkins then runs a special job we will call the update all versions job (how jenkins knows its a release is a complicated manner in part because the maven jenkins release plugin is pretty crappy as well).
4. The update all versions job knows about all the 20 projects. It is actually an aggregator pom to be specific with all the projects in the modules section in dependency order. Jenkins runs our magic groovy/bash foo that will pull all the projects update the versions to the latest and then checkin the poms (again done in dependency order based on the modules section).
5. For each project if the pom has changed (because of a version change in some dependency) it is checked in and then we immediately ping jenkins to run the corresponding job for that project (this is to preserve build dependency order otherwise you are at the mercy of the SCM Poll scheduler).

At this point I'm of the opinion it is a good thing to have the release and auto version a separate tool from your general build anyway.

Now you might think maven sort of sucks because of the problems listed above but this actually would be fairly difficult with a build tool that does not have a declarative easy to parse extendable syntax (aka XML).

In fact we add custom XML attributes through namespaces to help hint bash/groovy scripts (e.g. don't update this version).

In addition to @Connor Leech's answer.

If you want to create a new custom typography type of your own, define the following in your css file.

.text-foo {
  .text-emphasis-variant(#FFFFFF);
}

The mixin text-emphasis-variant is defined in Bootstrap's mixins.less file.

text='Python' searches for elements that have the exact text you provided:

import re
from BeautifulSoup import BeautifulSoup

html = """<p>exact text</p>
   <p>almost exact text</p>"""
soup = BeautifulSoup(html)
print soup(text='exact text')
print soup(text=re.compile('exact text'))

Output

[u'exact text']
[u'exact text', u'almost exact text']

"To see if the string 'Python' is located on the page http://python.org":

import urllib2
html = urllib2.urlopen('http://python.org').read()
print 'Python' in html # -> True

If you need to find a position of substring within a string you could do html.find('Python').

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".

You can't (and shouldn't) block processing with a sleep function. However, you can use setTimeout to kick off a function after a delay:

setTimeout(function(){alert("hi")}, 1000);

Depending on your needs, setInterval might be useful, too.

Use scp priv_key.pem source user@host:target if you need to connect using a private key.

or if using pscp then use pscp -i priv_key.ppk source user@host:target

The simple way, to actually merge specific files from two branches, not just replace specific files with ones from another branch.

Step one: Diff the branches

git diff branch_b > my_patch_file.patch

Creates a patch file of the difference between the current branch and branch_b

Step two: Apply the patch on files matching a pattern

git apply -p1 --include=pattern/matching/the/path/to/file/or/folder my_patch_file.patch

Useful notes on the options

You can use * as a wildcard in the include pattern.

Slashes don't need to be escaped.

Also, you could use --exclude instead and apply it to everything except the files matching the pattern, or reverse the patch with -R

The -p1 option is a holdover from the *Unix patch command and the fact that the patch file's contents prepend each file name with a/ or b/ (or more depending on how the patch file was generated) which you need to strip, so that it can figure out the real file to the path to the file the patch needs to be applied to.

Check out the man page for git-apply for more options.

Step three: there is no step three

Obviously you'd want to commit your changes, but who's to say you don't have some other related tweaks you want to do before making your commit.

The Scriptler Groovy script doesn't seem to get all the environment variables of the build. But what you can do is force them in as parameters to the script:

1. When you add the Scriptler build step into your job, select the option "Define script parameters"

2. Add a parameter for each environment variable you want to pass in. For example "Name: JOB_NAME", "Value: $JOB_NAME". The value will get expanded from the Jenkins build environment using '$envName' type variables, most fields in the job configuration settings support this sort of expansion from my experience.

3. In your script, you should have a variable with the same name as the parameter, so you can access the parameters with something like:

   println "JOB_NAME = $JOB_NAME"

I haven't used Sciptler myself apart from some experimentation, but your question posed an interesting problem. I hope this helps!

I've solve the issue. The solution is to not making virtual dir manualy and then copy app files here, but use 'Add Application...' option. Here is post that helped me http://social.msdn.microsoft.com/Forums/en-US/winformssetup/thread/7ad2acb0-42ca-4ee8-9161-681689b60dda/

It is a function expression, it stands for Immediately Invoked Function Expression (IIFE). IIFE is simply a function that is executed right after it is created. So insted of the function having to wait until it is called to be executed, IIFE is executed immediately. Let's construct the IIFE by example. Suppose we have an add function which takes two integers as args and returns the sum lets make the add function into an IIFE,

Step 1: Define the function

function add (a, b){
    return a+b;
}
add(5,5);

Step2: Call the function by wrap the entire functtion declaration into parentheses

(function add (a, b){
    return a+b;
})
//add(5,5);

Step 3: To invock the function immediatly just remove the 'add' text from the call.

(function add (a, b){
    return a+b;
})(5,5);

The main reason to use an IFFE is to preserve a private scope within your function. Inside your javascript code you want to make sure that, you are not overriding any global variable. Sometimes you may accidentaly define a variable that overrides a global variable. Let's try by example. suppose we have an html file called iffe.html and codes inside body tag are-

<body>
    <div id = 'demo'></div>
    <script>
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
    </script> 
</body>

Well, above code will execute with out any question, now assume you decleard a variable named document accidentaly or intentional.

<body>
    <div id = 'demo'></div>
    <script>
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
        const document = "hi there";
        console.log(document);
    </script> 
</body>

you will endup in a SyntaxError: redeclaration of non-configurable global property document.

But if your desire is to declear a variable name documet you can do it by using IFFE.

<body>
    <div id = 'demo'></div>
    <script>
        (function(){
            const document = "hi there";
            this.document.getElementById("demo").innerHTML = "Hello JavaScript!";
            console.log(document);
        })();
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
    </script> 
</body>

Output:

Let's try by an another example, suppose we have an calculator object like bellow-

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        console.log(calculator.add(5,10));
    </script> 
</body>

Well it's working like a charm, what if we accidently re-assigne the value of calculator object.

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        console.log(calculator.add(5,10));
        calculator = "scientific calculator";
        console.log(calculator.mul(5,5));
    </script> 
</body>

yes you will endup with a TypeError: calculator.mul is not a function iffe.html

But with the help of IFFE we can create a private scope where we can create another variable name calculator and use it;

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        var cal = (function(){

                div:function(a,b){
                    return a/b;
                }
            }
            console.log(this.calculator.mul(5,10));
            console.log(calculator.sub(10,5));

Yes, people use these terms interchangeably with regard to MySQL. Though oftentimes you will hear people inappropriately refer to the entire database server as the database.

encodeURIComponent() : assumes that its argument is a portion (such as the protocol, hostname, path, or query string) of a URI. Therefore it escapes the punctuation characters that are used to separate the portionsof a URI.

encodeURI(): is used for encoding existing url

CSS

.vr {
   border-right: 1px solid #ccc !important;
}

HTML

<div class="row">
   <div class="col-md-6 vr">
       <p>Column 1</p>
   </div>
   <div class="col-md-6">
       <p>Column 2</p>
   </div>
</div

Now, we can use class vr wherever we need to have a vertical-divider kind of appearance.

Hope it helps!

Using base graphics, the standard way to do this is to use axes=FALSE, then create your own axes using Axis (or axis). For example,

x <- 1:20
y <- runif(20)
plot(x, y, axes=FALSE, frame.plot=TRUE)
Axis(side=1, labels=FALSE)
Axis(side=2, labels=FALSE)

The lattice equivalent is

library(lattice)
xyplot(y ~ x, scales=list(alternating=0))

The pythonic way.

print "".join([ c if c.isalnum() else "*" for c in s ])

This doesn't deal with grouping multiple consecutive non-matching characters though, i.e.

"h^&i => "h**i not "h*i" as in the regex solutions.

As seen in the revision column of the Android SDK Manager, the latest published version of the Support Library is 22.2.1. You'll have to wait until 23.0.0 is published.

Edit: API 23 is already published. So u can use 23.0.0

Here is a more general solution:

int increment = 3;
for(int i = 0; i < theData.Length; i += increment)
{
   for(int j = 0; j < increment; j++)
   {
      if(i+j < theData.Length) {
         //theData[i + j] for the current index
      }
   }

}

Here is possibly the fastest way to query a large number of rows with Dapper using a list of IDs. I promise you this is faster than almost any other way you can think of (with the possible exception of using a TVP as given in another answer, and which I haven't tested, but I suspect may be slower because you still have to populate the TVP). It is planets faster than Dapper using IN syntax and universes faster than Entity Framework row by row. And it is even continents faster than passing in a list of VALUES or UNION ALL SELECT items. It can easily be extended to use a multi-column key, just add the extra columns to the DataTable, the temp table, and the join conditions.

public IReadOnlyCollection<Item> GetItemsByItemIds(IEnumerable<int> items) {
   var itemList = new HashSet(items);
   if (itemList.Count == 0) { return Enumerable.Empty<Item>().ToList().AsReadOnly(); }

   var itemDataTable = new DataTable();
   itemDataTable.Columns.Add("ItemId", typeof(int));
   itemList.ForEach(itemid => itemDataTable.Rows.Add(itemid));

   using (SqlConnection conn = GetConnection()) // however you get a connection
   using (var transaction = conn.BeginTransaction()) {
      conn.Execute(
         "CREATE TABLE #Items (ItemId int NOT NULL PRIMARY KEY CLUSTERED);",
         transaction: transaction
      );

      new SqlBulkCopy(conn, SqlBulkCopyOptions.Default, transaction) {
         DestinationTableName = "#Items",
         BulkCopyTimeout = 3600 // ridiculously large
      }
         .WriteToServer(itemDataTable);
      var result = conn
         .Query<Item>(@"
            SELECT i.ItemId, i.ItemName
            FROM #Items x INNER JOIN dbo.Items i ON x.ItemId = i.ItemId
            DROP TABLE #Items;",
            transaction: transaction,
            commandTimeout: 3600
         )
         .ToList()
         .AsReadOnly();
      transaction.Rollback(); // Or commit if you like
      return result;
   }
}

Be aware that you need to learn a little bit about Bulk Inserts. There are options about firing triggers (the default is no), respecting constraints, locking the table, allowing concurrent inserts, and so on.

We all know that PHP save errors in php_errors.log file.

But, that file contains a lot of data.

If we want to log our application data, we need to save it to a custom location.

We can use two parameters in the error_log function to achieve this.

http://php.net/manual/en/function.error-log.php

We can do it using:

error_log(print_r($v, TRUE), 3, '/var/tmp/errors.log');

Where,

print_r($v, TRUE) : logs $v (array/string/object) to log file. 3: Put log message to custom log file specified in the third parameter.

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS).

OR, you can use file_put_contents()

file_put_contents('/var/tmp/e.log', print_r($v, true), FILE_APPEND);

Where:

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS). print_r($v, TRUE) : logs $v (array/string/object) to log file. FILE_APPEND: Constant parameter specifying whether to append to the file if it exists, if file does not exist, new file will be created.

but I can't initialize my derived class, I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ?? so I'm thinking maybe in the PetStore default constructor I can call Farm()... so any Idea ???

Don't panic.

Farm constructor will be called in the constructor of PetStore, automatically.

See the base class inheritance calling rules: What are the rules for calling the superclass constructor?

This worked for me like a charm for downloading PNG and PDF.

Run this SQL statement (in the MySQL client, phpMyAdmin, or wherever) to retrieve all the MyISAM tables in your database.

Replace value of the name_of_your_db variable with your database name.

SET @DATABASE_NAME = 'name_of_your_db';

SELECT  CONCAT('ALTER TABLE `', table_name, '` ENGINE=InnoDB;') AS sql_statements
FROM    information_schema.tables AS tb
WHERE   table_schema = @DATABASE_NAME
AND     `ENGINE` = 'MyISAM'
AND     `TABLE_TYPE` = 'BASE TABLE'
ORDER BY table_name DESC;

Then, copy the output and run as a new SQL query.

When installing a tool globally it's to be used by a user as a command line utility anywhere, including outside of node projects. Global installs for a node project are bad because they make deployment more difficult.

npm 5.2+

The npx utility bundled with npm 5.2 solves this problem. With it you can invoke locally installed utilities like globally installed utilities (but you must begin the command with npx). For example, if you want to invoke a locally installed eslint, you can do:

npx eslint .

npm < 5.2

When used in a script field of your package.json, npm searches node_modules for the tool as well as globally installed modules, so the local install is sufficient.

So, if you are happy with (in your package.json):

"devDependencies": {
    "gulp": "3.5.2"
}
"scripts": {
    "test": "gulp test"
}

etc. and running with npm run test then you shouldn't need the global install at all.

Both methods are useful for getting people set up with your project since sudo isn't needed. It also means that gulp will be updated when the version is bumped in the package.json, so everyone will be using the same version of gulp when developing with your project.

Addendum:

It appears that gulp has some unusual behaviour when used globally. When used as a global install, gulp looks for a locally installed gulp to pass control to. Therefore a gulp global install requires a gulp local install to work. The answer above still stands though. Local installs are always preferable to global installs.

Your understanding is correct. The ApplicationContext is where your Spring beans live. The purpose of the ContextLoaderListener is two-fold:

1. to tie the lifecycle of the ApplicationContext to the lifecycle of the ServletContext and

2. to automate the creation of the ApplicationContext, so you don't have to write explicit code to do create it - it's a convenience function.

Another convenient thing about the ContextLoaderListener is that it creates a WebApplicationContext and WebApplicationContext provides access to the ServletContext via ServletContextAware beans and the getServletContext method.

I had the same problem caused by my script below. The problem was caused by url variable. When I added http://|web server name|/|application name| in front of /Reports/ReportPage.aspx ... it started to work.

        var url = '/Reports/ReportPage.aspx?ReportName=AssignmentReport';_x000D_
_x000D_
        if (url === '')_x000D_

Just thought I'd add that I've improved Mud's SimplerAES by adding a random IV that's passed back inside the encrypted string. This improves the encryption as encrypting the same string will result in a different output each time.

public class StringEncryption
{
    private readonly Random random;
    private readonly byte[] key;
    private readonly RijndaelManaged rm;
    private readonly UTF8Encoding encoder;

    public StringEncryption()
    {
        this.random = new Random();
        this.rm = new RijndaelManaged();
        this.encoder = new UTF8Encoding();
        this.key = Convert.FromBase64String("Your+Secret+Static+Encryption+Key+Goes+Here=");
    }

    public string Encrypt(string unencrypted)
    {
        var vector = new byte[16];
        this.random.NextBytes(vector);
        var cryptogram = vector.Concat(this.Encrypt(this.encoder.GetBytes(unencrypted), vector));
        return Convert.ToBase64String(cryptogram.ToArray());
    }

    public string Decrypt(string encrypted)
    {
        var cryptogram = Convert.FromBase64String(encrypted);
        if (cryptogram.Length < 17)
        {
            throw new ArgumentException("Not a valid encrypted string", "encrypted");
        }

        var vector = cryptogram.Take(16).ToArray();
        var buffer = cryptogram.Skip(16).ToArray();
        return this.encoder.GetString(this.Decrypt(buffer, vector));
    }

    private byte[] Encrypt(byte[] buffer, byte[] vector)
    {
        var encryptor = this.rm.CreateEncryptor(this.key, vector);
        return this.Transform(buffer, encryptor);
    }

    private byte[] Decrypt(byte[] buffer, byte[] vector)
    {
        var decryptor = this.rm.CreateDecryptor(this.key, vector);
        return this.Transform(buffer, decryptor);
    }

    private byte[] Transform(byte[] buffer, ICryptoTransform transform)
    {
        var stream = new MemoryStream();
        using (var cs = new CryptoStream(stream, transform, CryptoStreamMode.Write))
        {
            cs.Write(buffer, 0, buffer.Length);
        }

        return stream.ToArray();
    }
}

And bonus unit test

[Test]
public void EncryptDecrypt()
{
    // Arrange
    var subject = new StringEncryption();
    var originalString = "Testing123!£$";

    // Act
    var encryptedString1 = subject.Encrypt(originalString);
    var encryptedString2 = subject.Encrypt(originalString);
    var decryptedString1 = subject.Decrypt(encryptedString1);
    var decryptedString2 = subject.Decrypt(encryptedString2);

    // Assert
    Assert.AreEqual(originalString, decryptedString1, "Decrypted string should match original string");
    Assert.AreEqual(originalString, decryptedString2, "Decrypted string should match original string");
    Assert.AreNotEqual(originalString, encryptedString1, "Encrypted string should not match original string");
    Assert.AreNotEqual(encryptedString1, encryptedString2, "String should never be encrypted the same twice");
}

I got the same problem, in my case I was using svn tortoise with the application I mean. Using the cmd shell of windows in root mode I applied svn cleanup and then svn update.... Then you can comeback to the application mode aand it will work perfectly!

As the other answers suggest, editing/removing credentials in the Manage Windows Credentials work and does the job. However, you need to do this each time when the password changes or credentials do not work for some work. Using ssh key has been extremely useful for me where I don't have to bother about these again once I'm done creating a ssh-key and adding them on the server repository (github/bitbucket/gitlab).

Generating a new ssh-key

1. Open Git Bash.

2. Paste the text below, substituting in your repo's email address. $ ssh-keygen -t rsa -b 4096 -C "[email protected]"

3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

4. Then you'll be asked to type a secure passphrase. You can type a passphrase, hit enter and type the passphrase again.

Or, Hit enter twice for empty passphrase.

5. Copy this on the clipboard:

   clip < ~/.ssh/id_rsa.pub

And then add this key into your repo's profile. For e.g, on github->setting->SSH keys -> paste the key that you coppied ad hit add

Ref: https://help.github.com/en/enterprise/2.15/user/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key

You're done once and for all!

The same syntax works for Ms SQL server using podbc also.

import pyodbc
import pandas.io.sql as psql

cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=servername;DATABASE=mydb;UID=username;PWD=password') 
cursor = cnxn.cursor()
sql = ("""select * from mytable""")

df = psql.frame_query(sql, cnxn)
cnxn.close()

your code used in python2.x, you can use like this:

from urllib.request import urlopen
urlopen(url)

by the way, suggest another module called requests is more friendly to use, you can use pip install it, and use like this:

import requests
requests.get(url)
requests.post(url)

I thought it is easily to use, i am beginner too....hahah

Try this

$("#message span").text("hello world!");

function Errormessage(txt) {
    var elem = $("#message");
    elem.fadeIn("slow");
    // find the span inside the div and assign a text
    elem.children("span").text("your text");

    elem.children("a.close-notify").click(function() {
        elem.fadeOut("slow");
    });
}

Take a look at this example.

$("#wizard li").click(function () {
    alert($(this).index()); // alert index of li relative to ul parent
});

try

myDiv.offsetHeight 

console.log("Height:", myDiv.offsetHeight );

#myDiv { width: 100px; height: 666px; background: red}

<div id="myDiv"></div>

Use:

s.erase(std::remove_if(s.begin(), s.end(), my_predicate), s.end());

bool my_predicate(char c)
{
 return !(isalpha(c) || c=='_' || c==' '); // depending on you definition of special characters
}

And you'll get a clean string s.

erase() will strip it of all the special characters and is highly customisable with the my_predicate() function.

You don't have to add a . in getElementsByClassName, i.e.

var multibutton = angular.element(element.getElementsByClassName("multi-files"));

However, when using angular.element, you do have to use jquery style selectors:

angular.element('.multi-files');

should do the trick.

Also, from this documentation "If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.""

I have done it by the following way

1. Start cmd
2. Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
3. type mysqld --install

Like the following image. See for more information.

As an exercise, I would suggest doing the following:

public void save(String fileName) throws FileNotFoundException {
    PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
    for (Club club : clubs)
        pw.println(club.getName());
    pw.close();
}

This will write the name of each club on a new line in your file.

Soccer
Chess
Football
Volleyball
...

I'll leave the loading to you. Hint: You wrote one line at a time, you can then read one line at a time.

Every class in Java extends the Object class. As such you can override its methods. In this case, you should be interested by the toString() method. In your Club class, you can override it to print some message about the class in any format you'd like.

public String toString() {
    return "Club:" + name;
}

You could then change the above code to:

public void save(String fileName) throws FileNotFoundException {
    PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
    for (Club club : clubs)
         pw.println(club); // call toString() on club, like club.toString()
    pw.close();
}

this is best document I found describing getName(), getSimpleName(), getCanonicalName()

First of all you need to install json-loader:

npm i json-loader --save-dev

Then, there are two ways how you can use it:

1. In order to avoid adding json-loader in each import you can add to webpack.config this line:

   loaders: [
     { test: /\.json$/, loader: 'json-loader' },
     // other loaders 
   ]
   

   Then import json files like this

   import suburbs from '../suburbs.json';
   

2. Use json-loader directly in your import, as in your example:

   import suburbs from 'json!../suburbs.json';
   

Note: In webpack 2.* instead of keyword loaders need to use rules.,

also webpack 2.* uses json-loader by default

*.json files are now supported without the json-loader. You may still use it. It's not a breaking change.

v2.1.0-beta.28

That picture indeed shows that your 8081 is not in use. If suggestions above haven't helped, and your mobile device is connected to your computer via usb (and you have Android 5.0 (Lollipop) or above) you could try:

$ adb reconnect

This is not necessary in most cases, but just in case, let's reset your connection with your mobile and restart adb server. Finally:

$ adb reverse tcp:8081 tcp:8081

So, whenever your mobile device tries to access any port 8081 on itself it will be routed to the 8081 port on your PC.

Or, one could try

$ killall node

You could use

jQuery('#gregsButton').click(function() { 
    var mb = jQuery('#myDiv').text(); 
    alert("Value of div is: " + mb); 
});

Looks like there may be a conflict with using the $. Remember that the variable 'mb' will not be accessible outside of the event handler. Also, the text() function returns a string, no need to get mb.value.

In order to insert the text from activity2 to activity1, you first need to create a visit function in activity2.

public void visitactivity1()
{
    Intent i = new Intent(this, activity1.class);
    i.putExtra("key", message);
    startActivity(i);
}

After creating this function, you need to call it from your onCreate() function of activity2:

visitactivity1();

Next, go on to the activity1 Java file. In its onCreate() function, create a Bundle object, fetch the earlier message via its key through this object, and store it in a String.

    Bundle b = getIntent().getExtras();
    String message = b.getString("key", ""); // the blank String in the second parameter is the default value of this variable. In case the value from previous activity fails to be obtained, the app won't crash: instead, it'll go with the default value of an empty string

Now put this element in a TextView or EditText, or whichever layout element you prefer using the setText() function.

If there's any chance that your datetimes aren't strict calendar dates, you should consider using enddate exclusion comparisons... This will prevent you from missing any requests created during the date of Jan 31.

DateTime now = DateTime.Now;
DateTime thisMonth = new DateTime(now.Year, now.Month, 1);
DateTime lastMonth = thisMonth.AddMonths(-1);

var RequestIds = rdc.request
  .Where(r => lastMonth <= r.dteCreated)
  .Where(r => r.dteCreated < thisMonth)
  .Select(r => r.intRequestId);

Selected date at the example is interesting. Example code block is:

Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30);  //January 30th 2000
Date sDate = c1.getTime();

System.out.println(sDate);

and output Wed Mar 01 19:32:21 JST 2000.

When I first read the example i think that output is wrong but it is true:)

• Calendar.Month is starting from 0 so 1 means February.
• February last day is 28 so output should be 2 March.
• But selected year is important, it is 2000 which means February 29 so result should be 1 March.

This problem occurs because while creating the AVD manager in the "Create new Android virtual device(AVD)" dialog window ,"Snapshot" was marked as "Enabled" by me.

Solution:

Create a new AVD manager with the "Enabled" checkbox not checked and then try running the project with the newly created AVD manager as "Target" , the problem will not occur anymore

In default I didn't have this problem. So what I did is chmod -R 644 sessions to replicate the problem.

Afterwards I gave permissions to sessions folder by chmod -R 755 sessions

now my project code works again.

Reason it happens is you store your cache on file with lack of writing permissions.

The session configuration file is stored at config/session.php. Be sure to review the options available to you in this file. By default, Laravel is configured to use the file session driver, which will work well for many applications. In production applications, you may consider using the memcached or redis drivers for even faster session performance.

Solutions:

1 - As I have fixed above you can give 755 permission to sessions folder. 2 - You can use another session driver configuration.

file - sessions are stored in storage/framework/sessions. cookie - sessions are stored in secure, encrypted cookies. database - sessions are stored in a relational database. memcached / redis - sessions are stored in one of these fast, cache based stores. array - sessions are stored in a PHP array and will not be persisted.

Bear in mind; If you want to use memcached/redis you need to have them installed on your server or your docker redis container must be running.

JIT refers to execution engine in few of JVM implementations, one that is faster but requires more memory,is a just-in-time compiler. In this scheme, the bytecodes of a method are compiled to native machine code the first time the method is invoked. The native machine code for the method is then cached, so it can be re-used the next time that same method is invoked.

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

The answer by @AKX works on the command line, but not within a batch file. Within a batch file, you need an extra %, like this:

@echo off
for /R TutorialSteps %%F in (*.py) do echo %%~nF

You need to instruct the console to clear.

For serial terminals this was typically done through so called "escape sequences", where notably the vt100 set has become very commonly supported (and its close ANSI-cousin).

Windows has traditionally not supported such sequences "out-of-the-box" but relied on API-calls to do these things. For DOS-based versions of Windows, however, the ANSI.SYS driver could be installed to provide such support.

So if you are under Windows, you need to interact with the appropriate Windows API. I do not believe the standard Java runtime library contains code to do so.

You can reset settings for eclipse by deleting .metadata folder from your current workspace.

This will however remove all projects from your project explorer NOT workspace. So dont worry your projects have not gone anywhere.

You can import projects from your workspace like this : just make sure that you uncheck "Copy project into workspace".

Have a look here :

Here's a simple example using urllib2 that does a basic authentication against GitHub's API.

import urllib2

u='username'
p='userpass'
url='https://api.github.com/users/username'

# simple wrapper function to encode the username & pass
def encodeUserData(user, password):
    return "Basic " + (user + ":" + password).encode("base64").rstrip()

# create the request object and set some headers
req = urllib2.Request(url)
req.add_header('Accept', 'application/json')
req.add_header("Content-type", "application/x-www-form-urlencoded")
req.add_header('Authorization', encodeUserData(u, p))
# make the request and print the results
res = urllib2.urlopen(req)
print res.read()

Furthermore if you wrap this in a script and run it from a terminal you can pipe the response string to 'mjson.tool' to enable pretty printing.

>> basicAuth.py | python -mjson.tool

One last thing to note, urllib2 only supports GET & POST requests.
If you need to use other HTTP verbs like DELETE, PUT, etc you'll probably want to take a look at PYCURL

Add this line to the dependencies in build.gradle:

compile 'com.mcxiaoke.volley:library:1.0.+'

I solved this issue by adding this line

android.overridePathCheck=true

to

gradle.properties

As this message said

This warning can be disabled by using 
the command line flag -Dcom.android.build.gradle.overridePathCheck=true,
 or adding the line 
'com.android.build.gradle.overridePathCheck=true'
 to gradle.properties file in the project directory.

The join is called on the string:

print ", ".join(set_3)

You can do it using Kotlin extensions :

fun Context.getInstalledPackages(): List<String> {
    val packagesList = mutableListOf<String>()
    packageManager.getInstalledPackages(0).forEach {
        if ( it.applicationInfo.sourceDir.startsWith("/data/app/") && it.versionName != null)
            packagesList.add(it.packageName)
    }
    return packagesList
}

fun Context.isInDevice(packageName: String): Boolean {
    return getInstalledPackages().contains(packageName)
}

By useing this code below :

.classname{
    background-image: url(images/paper.jpg);
    background-position: center;
    background-size: cover;
    background-repeat: no-repeat;
}

Hope it works. Thanks

If the attribute you want to change doesn't exist or has been accidentally removed, then an exception occurs. I suggest you first create a new attribute and send it to a function like the following:

private void SetAttrSafe(XmlNode node,params XmlAttribute[] attrList)
    {
        foreach (var attr in attrList)
        {
            if (node.Attributes[attr.Name] != null)
            {
                node.Attributes[attr.Name].Value = attr.Value;
            }
            else
            {
                node.Attributes.Append(attr);
            }
        }
    }

Usage:

   XmlAttribute attr = dom.CreateAttribute("name");
   attr.Value = value;
   SetAttrSafe(node, attr);

One other thing. You may need to specify the -L option as well - eg

-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz

or you may end up with an error like

ld: cannot find -lbaz

I'm using GitKraken and Visual Studio 2017.

When GitKraken clones a repository, it leaves fetch address like "[email protected]:user/Repo.git", instead of "https://github.com/user/Repo.git".

To fix that, go to Team Explorer ? Settings ? Repository Settings ? Remotes ? Edit, and change "git@" to "https://" and ":" to "/".

I can also propose following solution for C++11.

for (auto p = 0U; p < sys.size(); p++) {

}

(C++ is not smart enough for auto p = 0, so I have to put p = 0U....)

I think you're looking for something like freopen()

Your default alignment is probably 4 bytes. Either the 30 byte element got 32, or the structure as a whole was rounded up to the next 4 byte interval.

Generally the verions of programs are linked to the version of your operating system. So if you were running gutsy you would either have to upgrade to the new jaunty jackalope version which has ruby 1.9 or add the respoistories for jaunty to your /etc/apt/sources.list file. Once you have done that you can start up the synaptic package manager and you should see it in there.

Regex regex = new Regex("%download#(\\d+?)%", RegexOptions.SingleLine);
Matches m = regex.Matches(input);

I think will do the trick (not tested).

In Kotlin, you can use the ktx extensions:

yourView.updateLayoutParams {
   height = <YOUR_HEIGHT>
}

You can use setState inside componentDidUpdate

For a non-regular expression approach, you can check Character.isWhitespace for each character.

boolean containsWhitespace(String s) {
    for (int i = 0; i < s.length(); ++i) {
        if (Character.isWhitespace(s.charAt(i)) {
            return true;
        }
    }
    return false;
}

Which are the white spaces in Java?

The documentation specifies what Java considers to be whitespace:

public static boolean isWhitespace(char ch)

Determines if the specified character is white space according to Java. A character is a Java whitespace character if and only if it satisfies one of the following criteria:

• It is a Unicode space character (SPACE_SEPARATOR, LINE_SEPARATOR, or PARAGRAPH_SEPARATOR) but is not also a non-breaking space ('\u00A0', '\u2007', '\u202F').
• It is '\u0009', HORIZONTAL TABULATION.
• It is '\u000A', LINE FEED.
• It is '\u000B', VERTICAL TABULATION.
• It is '\u000C', FORM FEED.
• It is '\u000D', CARRIAGE RETURN.
• It is '\u001C', FILE SEPARATOR.
• It is '\u001D', GROUP SEPARATOR.
• It is '\u001E', RECORD SEPARATOR.
• It is '\u001F', UNIT SEPARATOR.

glOrtho: 2D games, objects close and far appear the same size:

glFrustrum: more real-life like 3D, identical objects further away appear smaller:

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

The matrix for glOrtho is really simple, composed only of scaling and translation:

0,      scaley, 0,      translatey,
0,      0,      scalez, translatez,
0,      0,      0,      1

as mentioned in the OpenGL 2 docs.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

Using a comma may not be sufficient if you have multiple jQuery objects that need to be joined.

The .add() method adds the selected elements to the result set:

// classA OR classB
jQuery('.classA').add('.classB');

It's more verbose than '.classA, .classB', but lets you build more complex selectors like the following:

// (classA which has <p> descendant) OR (<div> ancestors of classB)
jQuery('.classA').has('p').add(jQuery('.classB').parents('div'));

In SQL Server 2008,2012,2014 you can insert multiple rows using a single SQL INSERT statement.

 INSERT INTO TableName ( Column1, Column2 ) VALUES
    ( Value1, Value2 ), ( Value1, Value2 )

Another way

INSERT INTO TableName (Column1, Column2 )
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2

if you did call config:cache during local development, you can undo this by deleting the bootstrap/cache/config.php file. and this is work for me.

Generate the scripts?

Generate a script to create the table then generate a script to insert the data.

check-out SP_ Genereate_Inserts for generating the data insert script.

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

This function check the special chars on key press and eliminates the value if it is not a number

function mobilevalid(id) {

    var feild = document.getElementById(id);

    if (isNaN(feild.value) == false) {
        if (feild.value.length == 1) {
            if (feild.value < 7) {
                feild.value = "";
            }
        } else if (feild.value.length > 10) {
            feild.value = feild.value.substr(0, feild.value.length - 1);
        }
        if (feild.value.charAt(0) < 7) {
            feild.value = "";
        }
    } else {
        feild.value = "";
    }

}

What exactly do you mean by "validation failure"? What are you validating? Are you referring to something like a syntax error (e.g. malformed XML)?

If that's the case, I'd say 400 Bad Request is probably the right thing, but without knowing what it is you're "validating", it's impossible to say.

Finding primes up to a 100 is especially nice and easy:

    printf("2 3 ");                        // first two primes are 2 and 3
    int m5 = 25, m7 = 49, i = 5, d = 4;
    for( ; i < 25; i += (d=6-d) )
    {
        printf("%d ", i);                  // all 6-coprimes below 5*5 are prime
    }
    for( ; i < 49; i += (d=6-d) )
    {
        if( i != m5) printf("%d ", i);
        if( m5 <= i ) m5 += 10;            // no multiples of 5 below 7*7 allowed!
    }
    for( ; i < 100; i += (d=6-d) )         // from 49 to 100,
    {
        if( i != m5 && i != m7) printf("%d ", i);
        if( m5 <= i ) m5 += 10;            //   sieve by multiples of 5,
        if( m7 <= i ) m7 += 14;            //                       and 7, too
    }

The square root of 100 is 10, and so this rendition of the sieve of Eratosthenes with the 2-3 wheel uses the multiples of just the primes above 3 that are not greater than 10 -- viz. 5 and 7 alone! -- to sieve the 6-coprimes below 100 in an incremental fashion.

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

I've had multenum for "Multi-column enumerated lists" recommended to me, but I've never actually used it myself, yet.

Edit: The syntax doesn't exactly look like you could easily copy+paste lists into the LaTeX code. So, it may not be the best solution for your use case!

here is my solution, which also works with the new html5 input-types:

/**
 * removes all value attributes from input/textarea/select-fields the element with the given css-selector
 * @param {string} ele css-selector of the element | #form_5
 */
function clear_form_elements(ele) {
    $(ele).find(':input').each(function() {
        switch (this.type) {
            case 'checkbox':
            case 'radio':
                this.checked = false;
            default:
                $(this).val('');
                break;
        }
    });
}

with gitbach line commande, use git update-ref to update reference of your local branch:

$ git update-ref -d refs/remotes/origin/[locked branch name]

then pull using $ git pull

[locked branch name] is the name of the branch that the error is happening because of mismatch of commit Ids.

ASP.Net 4.0 added the boolean ShowHeaderWhenEmpty property.

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.showheaderwhenempty.aspx

<asp:GridView runat="server" ID="GridView1" ShowHeaderWhenEmpty="true" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField HeaderText="First Name" DataField="FirstName" />
        <asp:BoundField HeaderText="Last Name" DataField="LastName" />
    </Columns>
</asp:GridView>

Note: the headers will not appear unless DataBind() is called with something other than null.

GridView1.DataSource = New List(Of String)
GridView1.DataBind()

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

json_decode() will return an object or array if second value it's true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

On Windows (msys) using Docker Toolbox/Machine, I had to add an extra / before /bin/bash to indicate that it was a *nix filepath.

So, docker run --rm -it <image>:latest //bin/bash

You can use the recode function from dplyr.

df <- iris %>%
     mutate(Species = recode(Species, setosa = "SETOSA",
         versicolor = "VERSICOLOR",
         virginica = "VIRGINICA"
     )
)

Do this

 let currentdate = new Date();
 let last3months = new Date(currentdate.setMonth(currentdate.getMonth()-3));

Javascript's setMonth method also takes care of the year. For instance, the above code will return 2020-01-29 if currentDate is set as new Date("2020-01-29")

I can recommend the SVG Primer (published by the W3C), which covers this topic: http://www.w3.org/Graphics/SVG/IG/resources/svgprimer.html#SVG_in_HTML

If you use <object> then you get raster fallback for free*:

<object data="your.svg" type="image/svg+xml">
  <img src="yourfallback.jpg" />
</object>

*) Well, not quite for free, because some browsers download both resources, see Larry's suggestion below for how to get around that.

2014 update:

• If you want a non-interactive svg, use <img> with script fallbacks to png version (for older IE and android < 3). One clean and simple way to do that:

  <img src="your.svg" onerror="this.src='your.png'">.

  This will behave much like a GIF image, and if your browser supports declarative animations (SMIL) then those will play.

• If you want an interactive svg, use either <iframe> or <object>.

• If you need to provide older browsers the ability to use an svg plugin, then use <embed>.

• For svg in css background-image and similar properties, modernizr is one choice for switching to fallback images, another is depending on multiple backgrounds to do it automatically:

  div {
      background-image: url(fallback.png);
      background-image: url(your.svg), none;
  }
  

  Note: the multiple backgrounds strategy doesn't work on Android 2.3 because it supports multiple backgrounds but not svg.

An additional good read is this blogpost on svg fallbacks.

a = dict(one=1, two=2, three=3)

Providing keyword arguments as in this example only works for keys that are valid Python identifiers. Otherwise, any valid keys can be used.

Heres a simpler, better way to do this using arraylists instead:

public static final <T> ArrayList<T> removeDuplicates(ArrayList<T> in){
    ArrayList<T> out = new ArrayList<T>();
    for(T t : in) 
        if(!out.contains(t)) 
            out.add(t);
    return out;
}

 [Route("api/controller/{one}/{two}")]
    public string Get(int One, int Two)
    {
        return "both params of the root link({one},{two}) and Get function parameters (one, two)  should be same ";
    }

Both params of the root link({one},{two}) and Get function parameters (one, two) should be same

Crazy idea...

You could play around with some pseudo elements, and create up/down arrows of css content hex codes. The only challange will be to precise the positioning of the arrow, but it may work:

input[type="number"] {_x000D_
    height: 100px;_x000D_
}_x000D_
_x000D_
.number-wrapper {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:after {_x000D_
    content: "\25B2";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    margin-left: -17px;_x000D_
    margin-top: 12%;_x000D_
    font-size: 11px;_x000D_
}_x000D_
_x000D_
.number-wrapper:hover:before {_x000D_
    content: "\25BC";_x000D_
    position: absolute;_x000D_
    color: blue;_x000D_
    left: 100%;_x000D_
    bottom: 0;_x000D_
    margin-left: -17px;_x000D_
    margin-bottom: -14%;_x000D_
    font-size: 11px;_x000D_
}

<span class='number-wrapper'>_x000D_
    <input type="number" />_x000D_
</span>

Angular CLI: 8.3.4 Node : 10.16.3 Angualr : 4.2.5

I used "dotnet new angular" command to generate the project, and it has generated 3 different modules in app folder (Although a simple test with ng new project-name just generates a single module.

see the modules in your project and decide wich module you want - then specify the name

ng g c componentName --module=[name-of-your-module]

You can read more about modules here: https://angular.io/guide/architecture-modules

Tcl has a builtin for this

$ tclsh
% string map {ab bc bc ab} abbc
bcab

This works by walking the string a character at a time doing string comparisons starting at the current position.

In perl:

perl -E '
    sub string_map {
        my ($str, %map) = @_;
        my $i = 0;
        while ($i < length $str) {
          KEYS:
            for my $key (keys %map) {
                if (substr($str, $i, length $key) eq $key) {
                    substr($str, $i, length $key) = $map{$key};
                    $i += length($map{$key}) - 1;
                    last KEYS;
                }
            }
            $i++;
        }
        return $str;
    }
    say string_map("abbc", "ab"=>"bc", "bc"=>"ab");
'

When building separate apks for different densities, drawable folders for other densities get stripped. This will make the icons appear blurry in devices that use launcher icons of higher density. Since, mipmap folders do not get stripped, it’s always best to use them for including the launcher icons.

UPDATE: Google stopped support for this method, that now returns a 404 (not found) error.

All this urls fetch the profile picture of a user:

https://www.google.com/s2/photos/profile/{user_id}
https://plus.google.com/s2/photos/profile/{user_id}
https://profiles.google.com/s2/photos/profile/{user_id}

They redirect to the same image url you get from Google API, an ugly link as
lh6.googleusercontent.com/-x1W2-XNKA-A/AAAAAAAAAAI/AAAAAAAAAAA/ooSNulbLz8U/photo.jpg

The simplest is to directly use like image source:

<img src="https://www.google.com/s2/photos/profile/{user_id}">

Otherwise to obtain exactly the same url of a Google API call you can read image headers,
for example in PHP:

$headers = get_headers("https://www.google.com/s2/photos/profile/{user_id}", 1);
echo "<img src=$headers[Location]>";

as described in article Fetch Google Plus Profile Picture using PHP.

This library helped me, I had a dict list of nested keys with the same name but with different values, every other solution kept overriding those nested keys.

https://pypi.org/project/deepmerge/

from deepmerge import always_merger

def process_parms(args):
    temp_list = []
    for x in args:
        with open(x, 'r') as stream:
            temp_list.append(yaml.safe_load(stream))

    return always_merger.merge(*temp_list)

You can try this

<select name="select1" onmousedown="if(this.options.length>8){this.size=8;}"  onchange='this.size=0;' onblur="this.size=0;">_x000D_
             <option value="1">This is select number 1</option>_x000D_
             <option value="2">This is select number 2</option>_x000D_
             <option value="3">This is select number 3</option>_x000D_
             <option value="4">This is select number 4</option>_x000D_
             <option value="5">This is select number 5</option>_x000D_
             <option value="6">This is select number 6</option>_x000D_
             <option value="7">This is select number 7</option>_x000D_
             <option value="8">This is select number 8</option>_x000D_
             <option value="9">This is select number 9</option>_x000D_
             <option value="10">This is select number 10</option>_x000D_
             <option value="11">This is select number 11</option>_x000D_
             <option value="12">This is select number 12</option>_x000D_
           </select>

It worked for me

I thought I had a speed issue with PyCharm but in the end it turned out that the output console in PyCharm does not necessarily emulate the output of state-of-the-art terminal applications.

Here's my solution: Click on drop down (arrow) symbol of your configuration -> click edit configuration -> click emulate terminal in output console -> click ok -> Run the configuration.

Jquery version

var currentdate = new Date();

$('#DatePickerInputID').val($.datepicker.formatDate('dd-M-y', currentdate));

Do use this:

highp float rand(vec2 co)
{
    highp float a = 12.9898;
    highp float b = 78.233;
    highp float c = 43758.5453;
    highp float dt= dot(co.xy ,vec2(a,b));
    highp float sn= mod(dt,3.14);
    return fract(sin(sn) * c);
}

Don't use this:

float rand(vec2 co){
    return fract(sin(dot(co.xy ,vec2(12.9898,78.233))) * 43758.5453);
}

You can find the explanation in Improvements to the canonical one-liner GLSL rand() for OpenGL ES 2.0

Google thrives on scraping websites of the world...so if it was "so illegal" then even Google won't survive ..of course other answers mention ways of mitigating IP blocks by Google. One more way to explore avoiding captcha could be scraping at random times (dint try) ..Moreover, I have a feeling, that if we provide novelty or some significant processing of data then it sounds fine at least to me...if we are simply copying a website.. or hampering its business/brand in some way...then it is bad and should be avoided..on top of it all...if you are a startup then no one will fight you as there is no benefit.. but if your entire premise is on scraping even when you are funded then you should think of more sophisticated ways...alternative APIs..eventually..Also Google keeps releasing (or depricating) fields for its API so what you want to scrap now may be in roadmap of new Google API releases..

I finally got this to work after, like, 4 separate tries after incurring the same problem that was originally posted. So here's what happened, I am not sure if this is an old issue now (2009-07-09), but I will post anyway in case it is helpful to you. What worked for me... might work for you...

1. start anew and delete the old private keys, public keys, and certificates in the keychain
2. go through the whole process, request a certificate from a certificate authority, get a new public key, a new private key, and a new certificate. Note: when it worked I had exactly one private key, one public key, and one certificate
3. Make a new provisioning profile (which utilizes the certificate that you just made) and put that in your organizer window in Xcode. Delete all the old BS.
4. Run it.

Hopefully this helps.

I tried the answer but it didn't worked for me. This is what i ended up doing:

Create a new controller DefaultController. In index action, i wrote one line redirect:

return Redirect("~/Default.aspx")

In RouteConfig.cs, change controller="Default" for the route.

 routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
        );

ES2015 UPDATE

ES2015 have String#includes method that checks whether a string contains another. This can be used if the target environment supports it. The method returns true if the needle is found in haystack else returns false.

ng-if="haystack.includes(needle)"

Here, needle is the string that is to be searched in haystack.

See Browser Compatibility table from MDN. Note that this is not supported by IE and Opera. In this case polyfill can be used.

You can use String#indexOf to get the index of the needle in haystack.

1. If the needle is not present in the haystack -1 is returned.
2. If needle is present at the beginning of the haystack 0 is returned.
3. Else the index at which needle is, is returned.

The index can be compared with -1 to check whether needle is found in haystack.

ng-if="haystack.indexOf(needle) > -1" 

For Angular(2+)

*ngIf="haystack.includes(needle)"

This should work:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
Assembly asm = Assembly.GetCallingAssembly();
String path = Path.GetDirectoryName(new Uri(asm.EscapedCodeBase).LocalPath);

string strLog4NetConfigPath = System.IO.Path.Combine(path, "log4net.config");

I am using this to deploy DLL file libraries along with some configuration file (this is to use log4net from within the DLL file).

There is a simple why that I prefered to the bundle due to the no duplicate data in memory. It consists of a init public method for the fragment

private ArrayList<Music> listMusics = new ArrayList<Music>();
private ListView listMusic;


public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    fragment.init(music);
    return fragment;
}

public void init(List<Music> music){
    this.listMusic = music;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
    Bundle savedInstanceState)
{

    View view = inflater.inflate(R.layout.musiclistview, container, false);
    listMusic = (ListView) view.findViewById(R.id.musicListView);
    listMusic.setAdapter(new MusicBaseAdapter(getActivity(), listMusics));

    return view;
}
}

In two words, you create an instance of the fragment an by the init method (u can call it as u want) you pass the reference of your list without create a copy by serialization to the instance of the fragment. This is very usefull because if you change something in the list u will get it in the other parts of the app and ofcourse, you use less memory.

I had the same problem (Python 2.7 Linux), I have found the solution and i would like to share it. In my case i had the structure below:

Booklet
-> __init__.py
-> Booklet.py
-> Question.py
default
-> __init_.py
-> main.py

In 'main.py' I had tried unsuccessfully all the combinations bellow:

from Booklet import Question
from Question import Question
from Booklet.Question import Question
from Booklet.Question import *
import Booklet.Question
# and many othet various combinations ...

The solution was much more simple than I thought. I renamed the folder "Booklet" into "booklet" and that's it. Now Python can import the class Question normally by using in 'main.py' the code:

from booklet.Booklet import Booklet
from booklet.Question import Question
from booklet.Question import AnotherClass

From this I can conclude that Package-Names (folders) like 'booklet' must start from lower-case, else Python confuses it with Class names and Filenames.

Apparently, this was not your problem, but John Fouhy's answer is very good and this thread has almost anything that can cause this issue. So, this is one more thing and I hope that maybe this could help others.

I was surprised nobody mentioned that iterating through an array with an integer index makes it easy for you to write faulty code by subscripting an array with the wrong index. For example, if you have nested loops using i and j as indices, you might incorrectly subscript an array with j rather than i and thus introduce a fault into the program.

In contrast, the other forms listed here, namely the range based for loop, and iterators, are a lot less error prone. The language's semantics and the compiler's type checking mechanism will prevent you from accidentally accessing an array using the wrong index.

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

Here is my version, pretty much stuff from this thread is integrated (same counts for the test cases):

Object.defineProperty(Object.prototype, "equals", {
    enumerable: false,
    value: function (obj) {
        var p;

        }

        // some checks for native types first

        if (typeof(this) === "function" || typeof(this) === "string" || this instanceof String) { 
            return this.toString() === obj.toString();
        }

            }
            return false;
        }

        // null.equals(null) and undefined.equals(undefined) do not inherit from the 
        // Object.prototype so we can return false when they are passed as obj
        if (typeof(this) !== typeof(obj) || obj === null || typeof(obj) === "undefined") {

            Object.keys(o).sort().forEach(function (key) {

                    }
                };

            }
        }

        // at least check them with JSON
        return JSON.stringify(sort(this)) === JSON.stringify(sort(obj));

If you are parsing the file after unzipping it, don't forget to use decode() method, is necessary when you open a file as binary.

import gzip
with gzip.open(file.gz, 'rb') as f:
    for line in f:
        print(line.decode().strip())

I added the vendor prefixes, and changed the animation to all, so you have both opacity and width that are animated.

Is this what you're looking for ? http://jsfiddle.net/u2FKM/3/

You could put the text into a div (or other container) with a width of 50%.

http://jsfiddle.net/6gjsd/

you can also use textbox events -

<input id="txt1" type="text" onchange="SetDefault($(this).val());" onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();">

function SetDefault(Text){
  alert(Text);
}

Try This

Well @sonida's answer helped me but Here I am posting complete step How I did it.

Change Mobile Device Settings:

1. Unplug the device from the computer
2. Go to Mobile Settings -> Storage.
3. In the ActionBar, click the option menu and choose "USB computer connection".
4. Check "Camera (PTP)" connection.

Download Google USB Driver:

5 .Now go to http://developer.android.com/sdk/win-usb.html#top and download USB Drivers --> unzip folder.

Install USB Drivers and Get Connected Device:

6.Then Right click on My computer -->Manage --> Device Manager.

7.You should seed Nexus 5 in the list.

8.Right click on Nexus 5 --> Update Driver Software... --> Browse my computer for driver software

9.select the folder we downloaded/unzipped "latest_usb_driver_windows" and Next ...Ok.

10.Now you will see pop-up dialogue asking for Allow device --> Ok.

11 .That's it!! device is connected now, you can see in DDMS.

Hope this will help someone.

I also had this problem recently, and it was the SELinux which caused it. I was trying to have the post-commit of subversion to notify Jenkins that the code has change so Jenkins would do a build and deploy to Nexus.

I had to do the following to get it to work.

1) First I checked if SELinux is enabled:

    less /selinux/enforce

This will output 1 (for on) or 0 (for off)

2) Temporary disable SELinux:

    echo 0 > /selinux/enforce

Now test see if it works now.

3) Enable SELinux:

    echo 1 > /selinux/enforce

Change the policy for SELinux.

4) First view the current configuration:

    /usr/sbin/getsebool -a | grep httpd

This will give you: httpd_can_network_connect --> off

5) Set this to on and your post-commit will work with SELinux:

    /usr/sbin/setsebool -P httpd_can_network_connect on

Now it should be working again.

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

You can not post to Facebook walls automatically without creating an application and using the templated feed publisher as Frank pointed out.

The only thing you can do is use the 'share' widgets that they provide, which require user interaction.

Mongoose basically wraps mongodb's api to give you a pseudo relational db api so queries are not going to be exactly like mongodb queries. Mongoose findOne query returns a query object, not a document. You can either use a callback as the solution suggests or as of v4+ findOne returns a thenable so you can use .then or await/async to retrieve the document.

// thenables
Auth.findOne({nick: 'noname'}).then(err, result) {console.log(result)};
Auth.findOne({nick: 'noname'}).then(function (doc) {console.log(doc)});

// To use a full fledge promise you will need to use .exec()
var auth = Auth.findOne({nick: 'noname'}).exec();
auth.then(function (doc) {console.log(doc)});

// async/await
async function auth() {
  const doc = await Auth.findOne({nick: 'noname'}).exec();
  return doc;
}
auth();

See the docs if you would like to use a third party promise library.

Something important to add: When using INSERT IGNORE and you do have key violations, MySQL does NOT raise a warning!

If you try for instance to insert 100 records at a time, with one faulty one, you would get in interactive mode:

Query OK, 99 rows affected (0.04 sec)

Records: 100 Duplicates: 1 Warnings: 0

As you see: No Warnings! This behavior is even wrongly described in the official Mysql Documentation.

If your script needs to be informed, if some records have not been added (due to key violations) you have to call mysql_info() and parse it for the "Duplicates" value.

Late to the party, but for anyone tasked with creating their own or wants to see how this would work, here's the function with an added bonus of rearranging the start-stop values based on the desired increment:

def RANGE(start, stop=None, increment=1):
    if stop is None:
        stop = start
        start = 1

    value_list = sorted([start, stop])

    if increment == 0:
        print('Error! Please enter nonzero increment value!')
    else:
        value_list = sorted([start, stop])
        if increment < 0:
            start = value_list[1]
            stop = value_list[0]
            while start >= stop:
                worker = start
                start += increment
                yield worker
        else:
            start = value_list[0]
            stop = value_list[1]
            while start < stop:
                worker = start
                start += increment
                yield worker

Negative increment:

for i in RANGE(1, 10, -1):
    print(i)

Or, with start-stop reversed:

for i in RANGE(10, 1, -1):
    print(i)

Output:

10
9
8
7
6
5
4
3
2
1

Regular increment:

for i in RANGE(1, 10):
    print(i)

Output:

1
2
3
4
5
6
7
8
9

Zero increment:

for i in RANGE(1, 10, 0):
    print(i)

Output:

'Error! Please enter nonzero increment value!'

Supposing the list may be long and the numbers may repeat, consider using the SortedList type from the Python sortedcontainers module. The SortedList type will automatically maintain the tuples in order by number and allow for fast searching.

For example:

from sortedcontainers import SortedList
sl = SortedList([(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")])

# Get the index of 53:

index = sl.bisect((53,))

# With the index, get the tuple:

tup = sl[index]

This will work a lot faster than the list comprehension suggestion by doing a binary search. The dictionary suggestion will be faster still but won't work if there could be duplicate numbers with different strings.

If there are duplicate numbers with different strings then you need to take one more step:

end = sl.bisect((53 + 1,))

results = sl[index:end]

By bisecting for 54, we will find the end index for our slice. This will be significantly faster on long lists as compared with the accepted answer.

I was having trouble with the autoplay from waldir's solution... using autoplay, the video was playing when the page loaded, not when the div got displayed.

This solution worked for me except I replaced

<a class="introVid" href="#video">Watch the video</a></p>

with

<a class="introVid" href="#video"><img src="images/NEWTHUMB.jpg" style="cursor:pointer" /></a>

so that it would use my thumbnail in place of the text link.

if you just use react native so you can use the following code

<View style={{flex:1}}>

{/* Your Main Content*/}
<View style={{flex:3}}>

<ScrollView>
   {/* Your List View ,etc */}
</ScrollView>

</View>

{/* Your Footer */}
<View style={{flex:1}}>
   {/*Elements*/}
</View>


 </View>

also, you can use https://docs.nativebase.io/ in your react native project and then do something like the following

<Container>

{/*Your Main Content*/}
<Content>

<ScrollView>
   {/* Your List View ,etc */}
</ScrollView>

</Content>

{/*Your Footer*/}
<Footer>
   {/*Elements*/}
</Footer>

You have forgotten to mark the getProducts return type as an array. In your getProducts it says that it will return a single product. So change it to this:

public getProducts(): Observable<Product[]> {
    return this.http.get<Product[]>(`api/products/v1/`);
  }

Use Calendar

Calendar.getInstance().get(Calendar.MILLISECOND);

or

Calendar c=Calendar.getInstance();
c.setTime(new Date()); /* whatever*/
//c.setTimeZone(...); if necessary
c.get(Calendar.MILLISECOND);

In practise though I think it will nearly always equal System.currentTimeMillis()%1000; unless someone has leap-milliseconds or some calendar is defined with an epoch not on a second-boundary.

You need to join the two tables:

select p.id, p.first, p.middle, p.last, p.age,
       a.id as address_id, a.street, a.city, a.state, a.zip
from Person p inner join Address a on p.id = a.person_id
where a.zip = '97229';

This will select all of the columns from both tables. You could of course limit that by choosing different columns in the select clause.

Found a solution on this website

All you need is to add the following to your web.config

<configuration>
  <system.web>
    <webServices>
      <protocols>
        <add name="HttpGet"/>
        <add name="HttpPost"/>
      </protocols>
    </webServices>
  </system.web>
</configuration>

More info from Microsoft

For tab separated values the code below can be used

sort -t$'\t' -k2 -n

-r can be used for getting data in descending order.
-n for numerical sort
-k, --key=POS1[,POS2] where k is column in file
For descending order below is the code

sort -t$'\t' -k2 -rn

jQuery plugin scrollintoview() increases usability

Instead of default DOM implementation you can use a plugin that animates movement and doesn't have any unwanted effects. Here's the simplest way of using it with defaults:

$("yourTargetLiSelector").scrollintoview();

Anyway head over to this blog post where you can read all the details and will eventually get you to GitHub source codeof the plugin.

This plugin automatically searches for the closest scrollable ancestor element and scrolls it so that selected element is inside its visible view port. If the element is already in the view port it doesn't do anything of course.

For importing database file in .sql.gz format, remove definer and import using below command

zcat path_to_db_to_import.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db_name

1. Earlier, export database in .sql.gz format using below command.

   mysqldump -u user -p old_db | gzip -9 > path_to_db_exported.sql.gz;

2. Import that exported database and removing definer using below command,

   zcat path_to_db_exported.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db

Unfortunately oracle doesnot support auto_increment like mysql does. You need to put a little extra effort to get that.

say this is your table -

CREATE TABLE MYTABLE (
  ID NUMBER NOT NULL,
  NAME VARCHAR2(100)
  CONSTRAINT "PK1" PRIMARY KEY (ID)
);

You will need to create a sequence -

CREATE SEQUENCE S_MYTABLE
START WITH 1
INCREMENT BY 1
CACHE 10;

and a trigger -

CREATE OR REPLACE TRIGGER T_MYTABLE_ID
BEFORE INSERT
ON MYTABLE
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
  if(:new.ID is null) then
  SELECT S_MYTABLE.nextval
  INTO :new.ID
  FROM dual;
  end if;
END;
/

ALTER TRIGGER "T_MYTABLE_ID" ENABLE;

It depends on where you are looking for the information from.

If you are looking for the information from the console you can use the jps command. The command gives output similar to the Unix ps command and comes with the JDK since I believe 1.5

If you are looking from the process the RuntimeMXBean (as said by Wouter Coekaerts) is probably your best choice. The output from getName() on Windows using Sun JDK 1.6 u7 is in the form [PROCESS_ID]@[MACHINE_NAME]. You could however try to execute jps and parse the result from that:

String jps = [JDK HOME] + "\\bin\\jps.exe";
Process p = Runtime.getRuntime().exec(jps);

If run with no options the output should be the process id followed by the name.

import React, { useEffect, useRef } from 'react';

function Example() {

    let inp = useRef();
    useEffect(() => {
        if (!inp && !inp.current) return;
        inp.current.focus();
        return () => inp = null;
    });

    const handleSubmit = () => {
        //...
    }

    return (
        <form
            onSubmit={e => {
                e.preventDefault();
                handleSubmit(e);
            }}
        >
            <input
                name="fakename"
                defaultValue="...."
                ref={inp}
                type="radio"
                style={{
                    position: "absolute",
                    opacity: 0
                }}
            />
            <button type="submit">
                submit
            </button>
        </form>
    )
}

Enter code here sometimes in popups it would not work to binding just a form and passing the onSubmit to the form because form may not have any input.

In this case if you bind the event to the document by doing document.addEventListener it will cause problem in another parts of the application.

For solving this issue we should wrap a form and should put a input with what is hidden by css, then you focus on that input by ref it will be work correctly.

It's because you can't resolve the host name Maybe DNS problems, host is unreachable...

try to use IP address instead of host name... ping this host name... nslookup it...

Simplest way for me:

from urlextract import URLExtract
from requests import get

url = "sample.com/samplepage/"
req = requests.get(url)
text = req.text
# or if you already have the html source:
# text = "This is html for ex <a href='http://google.com/'>Google</a> <a href='http://yahoo.com/'>Yahoo</a>"
text = text.replace(' ', '').replace('=','')
extractor = URLExtract()
print(extractor.find_urls(text))

output:

['http://google.com/', 'http://yahoo.com/']

The | operator in a regular expression means or. That is to say either string1 or string2 will match. You could do:

grep 'string1' filename | grep 'string2'

which will pipe the results from the first command into the second grep. That should give you only lines that match both.

You cannot change the DataType after the Datatable is filled with data. However, you can clone the Data table, change the column type and load data from previous data table to the cloned table as shown below.

DataTable dtCloned = dt.Clone();
dtCloned.Columns[0].DataType = typeof(Int32);
foreach (DataRow row in dt.Rows) 
{
    dtCloned.ImportRow(row);
}

You're passing link=$a and link=$b in the hrefs for A and B, respectively. They are treated as strings, not variables. The following should fix that for you:

echo '<a href="pass.php?link=' . $a . '">Link 1</a>';

// and

echo '<a href="pass.php?link=' . $b . '">Link 2</a>';

The value of $a also isn't included on pass.php. I would suggest making a common variable file and include it on all necessary pages.

Why not just use a custom format for the cell you need to quote?

If you set a custom format to the cell column, all values will take on that format.

For numbers....like a zip code....it would be this '#' For string text, it would be this '@'

You save the file as csv format, and it will have all the quotes wrapped around the cell data as needed.

I just had a related problem (which is how I found this thread), where my dynamically added row and column styles were not taking effect. I usually consider SuspendLayout()/ResumeLayout() as optimizations, but in this case, wrapping my code in them made the rows and columns behave correctly.

Redirect the output to a file like this:

./a.sh > somefile 2>&1 &

This will redirect both stdout and stderr to the same file. If you want to redirect stdout and stderr to two different files use this:

./a.sh > stdoutfile 2> stderrfile &

You can use /dev/null as one or both of the files if you don't care about the stdout and/or stderr.

See bash manpage for details about redirections.

There have been plenty of responses but the overall lesson seems to be that you can use multiple JOINS in a where clause; also techonthenet.com (my boss recommended it to me, that's how I found it) has good SQL tutorials if you ever have another question and you just want to try and figure it out.

SELECT table1.column1
FROM table1
WHERE table1 > 0 (or whatever you want to specify)
INNER JOIN table1 
ON table1.column1 = table2.column1

I created function from @Ruel answer. You can use this:

function get_valueFromStringUrl($url , $parameter_name)
{
    $parts = parse_url($url);
    if(isset($parts['query']))
    {
        parse_str($parts['query'], $query);
        if(isset($query[$parameter_name]))
        {
            return $query[$parameter_name];
        }
        else
        {
            return null;
        }
    }
    else
    {
        return null;
    }
}

Example:

$url = "https://example.com/test/the-page-here/1234?someurl=key&[email protected]";
echo get_valueFromStringUrl($url , "email");

Thanks to @Ruel

Normally a jdk installation has javac in the environment path variables ... so if you check for javac in the path, that's pretty much a good indicator that you have a jdk installed.

Here is another option to see if a cell exists inside a range. In case you have issues with the Intersect solution as I did.

If InStr(range("NamedRange").Address, range("IndividualCell").Address) > 0 Then
    'The individual cell exists in the named range
Else
    'The individual cell does not exist in the named range
End If

InStr is a VBA function that checks if a string exists within another string.

https://msdn.microsoft.com/en-us/vba/language-reference-vba/articles/instr-function

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761

[myButton setTitle: @"myTitle" forState: UIControlStateNormal];

Use UIControlStateNormal to set your title.

There are couple of states that UIbuttons provide, you can have a look:

[myButton setTitle: @"myTitle" forState: UIControlStateApplication];
[myButton setTitle: @"myTitle" forState: UIControlStateHighlighted];
[myButton setTitle: @"myTitle" forState: UIControlStateReserved];
[myButton setTitle: @"myTitle" forState: UIControlStateSelected];
[myButton setTitle: @"myTitle" forState: UIControlStateDisabled];

Old question but what I've found is that, all you need is to add the ppk file. Settings -> Connections -> SFTP -> Add keyfile User name and the host is same as what you would provide when using putty which is mentioned in http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-connect-to-instance-linux.html Might help someone.

I use Pokémon database as an example, the columns for my data base are

['Name', '#', 'Type 1', 'Type 2', 'Total', 'HP', 'Attack', 'Defense', 'Sp. Atk', 'Sp. Def', 'Speed', 'Generation', 'Legendary']

Here is the code:

import pandas as pd
    df = pd.read_html('https://gist.github.com/armgilles/194bcff35001e7eb53a2a8b441e8b2c6')[0] 
    cols = df.columns.to_list()
    cos_end= ["Name", "Total", "HP", "Defense"]

    for i, j in enumerate(cos_end, start=(len(cols)-len(cos_end))):
        cols.insert(i, cols.pop(cols.index(j)))
        print(cols)
        
    df = df.reindex(columns=cols)

    print(df)

This is because the StreamReader closes the underlying stream automatically when being disposed of. The using statement does this automatically.

However, the StreamWriter you're using is still trying to work on the stream (also, the using statement for the writer is now trying to dispose of the StreamWriter, which is then trying to close the stream).

The best way to fix this is: don't use using and don't dispose of the StreamReader and StreamWriter. See this question.

using (var ms = new MemoryStream())
{
    var sw = new StreamWriter(ms);
    var sr = new StreamReader(ms);

    sw.WriteLine("data");
    sw.WriteLine("data 2");
    ms.Position = 0;

    Console.WriteLine(sr.ReadToEnd());                        
}

If you feel bad about sw and sr being garbage-collected without being disposed of in your code (as recommended), you could do something like that:

StreamWriter sw = null;
StreamReader sr = null;

try
{
    using (var ms = new MemoryStream())
    {
        sw = new StreamWriter(ms);
        sr = new StreamReader(ms);

        sw.WriteLine("data");
        sw.WriteLine("data 2");
        ms.Position = 0;

        Console.WriteLine(sr.ReadToEnd());                        
    }
}
finally
{
    if (sw != null) sw.Dispose();
    if (sr != null) sr.Dispose();
}

What @gfrs said is correct, you need to set the Module. However I once ran into an issue that my class wasn't listed in the Class dropdown. Eventually I removed the swift file, re-started Xcode and re-created the file. Finally the class was listed and could be used in Storyboard.

Also have a look at this answer, which looks like to solve the 'real' problem I encountered.

This code works both in Eclipse and in Exported Runnable JAR

private String writeResourceToFile(String resourceName) throws IOException {
    File outFile = new File(certPath + File.separator + resourceName);

    if (outFile.isFile())
        return outFile.getAbsolutePath();
    
    InputStream resourceStream = null;
    
    // Java: In caso di JAR dentro il JAR applicativo 
    URLClassLoader urlClassLoader = (URLClassLoader)Cypher.class.getClassLoader();
    URL url = urlClassLoader.findResource(resourceName);
    if (url != null) {
        URLConnection conn = url.openConnection();
        if (conn != null) {
            resourceStream = conn.getInputStream();
        }
    }
    
    if (resourceStream != null) {
        Files.copy(resourceStream, outFile.toPath(), StandardCopyOption.REPLACE_EXISTING);
        return outFile.getAbsolutePath();
    } else {
        System.out.println("Embedded Resource " + resourceName + " not found.");
    }
    
    return "";
}   

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

Git Isn't Hard

Nov 23, 2008

When we tell people why they should use Git over Subversion, the go-to line is, “Git does Subversion better than Subversion, but it does a lot more than that.”

The “lot more” is comprised of a bunch of stuff that makes Git really shine, but it can be pretty overwhelming for those coming from other SCM’s like Subversion.

That said, there’s nothing stopping you from using Git just like you use Subversion while you’re making the transition.

Assuming you’ve installed the necessary software and have a remote repository somewhere, this is how you would grab the code and push your changes back with Subversion:

$ svn checkout svn://foo.googlecode.com/svn/trunk foo
# make your changes
$ svn commit -m "my first commit"

And how would you do it in Git:

$ git clone [email protected]:pjhyett/foo.git
# make your changes
$ git commit -a -m "my first commit"
$ git push

One more command to make it happen in Git. That extra command has large implications, but for the purposes of this post, that’s all we’re talking about, one extra command.

See, it really isn’t that hard.

Update: I’d be remiss to not also mention that the equivalent of updating your local copy in Subversion compared to Git is svn update and git pull, respectively. Only one command in both cases.

My Jenkins pipeline step shown below failed with the same error.

       steps {
            echo 'Building ...' 
            sh 'sh ./Tools/build.sh'
        }

In my "build.sh" script file "docker run" command output this error when it was executed by Jenkins job. However it was working OK when the script ran in the shell terminal.The error happened because of -t option passed to docker run command that as I know tries to allocate terminal and fails if there is no terminal to allocate.

In my case I have changed the script to pass -t option only if a terminal could be detected. Here is the code after changes :

DOCKER_RUN_OPTIONS="-i --rm"

# Only allocate tty if we detect one
if [ -t 0 ] && [ -t 1 ]; then
    DOCKER_RUN_OPTIONS="$DOCKER_RUN_OPTIONS -t"
fi

docker run $DOCKER_RUN_OPTIONS --name my-container-name  my-image-tag

header file lives at

/usr/include/SDL/SDL.h

       __OR__

/usr/include/SDL2/SDL.h  #  for SDL2

in your c++ code pull in this header using

#include <SDL.h>

       __OR__

#include <SDL2/SDL.h>    // for SDL2

you have the correct usage of

sdl-config --cflags --libs

       __OR__

sdl2-config --cflags --libs   #  sdl2

which will give you

-I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
-L/usr/lib/x86_64-linux-gnu -lSDL

       __OR__

-I/usr/include/SDL2 -D_REENTRANT
-lSDL2

at times you may also see this usage which works for a standard install

pkg-config --cflags --libs sdl

       __OR__

pkg-config --cflags --libs sdl2   #  sdl2

which supplies you with

-D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -lSDL

       __OR__

-D_REENTRANT -I/usr/include/SDL2 -lSDL2   #  SDL2

Try this

1. npm uninstall angular-cli
2. npm install @angular/cli --save-dev

str.startswith allows you to supply a tuple of strings to test for:

if link.lower().startswith(("js", "catalog", "script", "katalog")):

From the docs:

str.startswith(prefix[, start[, end]])

Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

Below is a demonstration:

>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>

Here's a nice easy way I found:

h <- hist(g, breaks = 10, density = 10,
          col = "lightgray", xlab = "Accuracy", main = "Overall") 
xfit <- seq(min(g), max(g), length = 40) 
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g)) 
yfit <- yfit * diff(h$mids[1:2]) * length(g) 

lines(xfit, yfit, col = "black", lwd = 2)

The specificity is calculated based on the amount of id, class and tag selectors in your rule. Id has the highest specificity, then class, then tag. Your first rule is now more specific than the second one, since they both have a class selector, but the first one also has two tag selectors.

To make the second one override the first one, you can make more specific by adding information of it's parents:

table.rule1 tr td.rule2 {
    background-color: #ffff00;
}

Here is a nice article for more information on selector precedence.
