Programs & Examples On #Mysql escape string

After a little more research, I came across iText, a PDF and RTF-file creation API. I think I can use the RTF generation to create a Doc-readable file that can then be edited using Doc and re-saved.

Anyone have any experience with iText, used in this fashion?

You can wrap your canvas element in a parent div, relatively positioned, then give that div the height you want, setting maintainAspectRatio: false in your options

//HTML
<div id="canvasWrapper" style="position: relative; height: 80vh/500px/whatever">
<canvas id="chart"></canvas>
</div>

<script>
new Chart(somechart, {
options: {
    responsive: true,
    maintainAspectRatio: false

/*, your other options*/

}
});
</script>

You don't have to use gdb. GCC will do it.

 gcc -S foo.c

This will create foo.s which is the assembly.

gcc -m32 -c -g -Wa,-a,-ad foo.c > foo.lst

The above version will create a listing file that has both the C and the assembly generated by it. GCC FAQ

If you're using SQL (which you didn't say):

select cast(column as varchar(200)) from table 

You can use it in any statement, for example:

select value where othervalue in( select cast(column as varchar(200)) from table)
from othertable

If you want to do a join query, the answer is here already in another post :)

I am using django==1.11. The answer get the most vote is actually wrong. Checking the document from django, it says:

initial -- A value to use in this Field's initial display. This value is not used as a fallback if data isn't given.

And if you dig into the code of form validation process, you will find that, for each fields, form will call it's widget's value_from_datadict to get actual value, so this is the place where we can inject default value.

To do this for BooleanField, we can inherit from CheckboxInput, override default value_from_datadict and init function.

class CheckboxInput(forms.CheckboxInput):
    def __init__(self, default=False, *args, **kwargs):
        super(CheckboxInput, self).__init__(*args, **kwargs)
        self.default = default

    def value_from_datadict(self, data, files, name):
        if name not in data:
            return self.default
        return super(CheckboxInput, self).value_from_datadict(data, files, name)

Then use this widget when creating BooleanField.

class ExampleForm(forms.Form):
    bool_field = forms.BooleanField(widget=CheckboxInput(default=True), required=False)

Found the solution in Spring security examples posted in Github.

WebSecurityConfigurerAdapter has a overloaded configure message that takes WebSecurity as argument which accepts ant matchers on requests to be ignored.

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/authFailure");
}

See Spring Security Samples for more details

Yes, this is a 'new style' object. It was a feature introduced in python2.2.

New style objects have a different object model to classic objects, and some things won't work properly with old style objects, for instance, super(), @property and descriptors. See this article for a good description of what a new style class is.

SO link for a description of the differences: What is the difference between old style and new style classes in Python?

You could try setting the failOnError property (see plugin documentation) to false:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>2.9</version>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
            <configuration>
              <failOnError>false</failOnError>
            </configuration>
        </execution>
    </executions>
</plugin>

As you can see from the docs, the default value is true.

You will need to define the repository outside of buildscript. The buildscript configuration block only sets up the repositories and dependencies for the classpath of your build script but not your application.

Here's a way you can request info about the browser being used, you can use this to do your if statement

System.Web.HttpBrowserCapabilities browser = Request.Browser;
    string s = "Browser Capabilities\n"
        + "Type = "                    + browser.Type + "\n"
        + "Name = "                    + browser.Browser + "\n"
        + "Version = "                 + browser.Version + "\n"
        + "Major Version = "           + browser.MajorVersion + "\n"
        + "Minor Version = "           + browser.MinorVersion + "\n"
        + "Platform = "                + browser.Platform + "\n"
        + "Is Beta = "                 + browser.Beta + "\n"
        + "Is Crawler = "              + browser.Crawler + "\n"
        + "Is AOL = "                  + browser.AOL + "\n"
        + "Is Win16 = "                + browser.Win16 + "\n"
        + "Is Win32 = "                + browser.Win32 + "\n"
        + "Supports Frames = "         + browser.Frames + "\n"
        + "Supports Tables = "         + browser.Tables + "\n"
        + "Supports Cookies = "        + browser.Cookies + "\n"
        + "Supports VBScript = "       + browser.VBScript + "\n"
        + "Supports JavaScript = "     + 
            browser.EcmaScriptVersion.ToString() + "\n"
        + "Supports Java Applets = "   + browser.JavaApplets + "\n"
        + "Supports ActiveX Controls = " + browser.ActiveXControls 
              + "\n";

Add second parameter

You need to pass additional parameter to your function:

function parts($site_url, $part) { 
    $structure = 'http://' . $site_url . 'content/'; 
    echo $structure . $part . '.php'; 
}

In case of closures

If you'd rather use closures then you can import variable to the current scope (the use keyword):

$parts = function($part) use ($site_url) { 
    $structure = 'http://' . $site_url . 'content/'; 
    echo $structure . $part . '.php'; 
};

global - a bad practice

This post is frequently read, so something needs to be clarified about global. Using it is considered a bad practice (refer to this and this).

For the completeness sake here is the solution using global:

function parts($part) { 
    global $site_url;
    $structure = 'http://' . $site_url . 'content/'; 
    echo($structure . $part . '.php'); 
}

It works because you have to tell interpreter that you want to use a global variable, now it thinks it's a local variable (within your function).

Suggested reading:

• Variable scope in PHP
• Anonymous functions

The new and delete operators can operate on classes and structures, whereas malloc and free only work with blocks of memory that need to be cast.

Using new/delete will help to improve your code as you will not need to cast allocated memory to the required data structure.

In Ubuntu 18.04, We can install java like a normal package without using an external repository

Just run this command

sudo apt install openjdk-8-jdk

You can use:

<asp:textbox id="textBox1" style="text-align:center"></asp:textbox>

Or this:

textbox.Style["text-align"] = "center"; //right, left

I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:

.ui-helper-center {
    text-align: center;
}

And then add the ui-helper-center class to the table cells for which you wish to control the alignment:

<td class="ui-helper-center">Content</td>

EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.

See Gabe's answer for how to include the CSS rule into your page.

You can also do this easily with gitk.

> gitk branch1 branch2

First click on the tip of branch1. Now right-click on the tip of branch2 and select Diff this->selected.

Base64 encoding converts three 8-bit bytes (0-255) into four 6-bit bytes (0-63 aka base64). Each of the four bytes indexes an ASCII string which represents the final output as four 8-bit ASCII characters. The indexed string is typically 'A-Za-z0-9+/' with '=' used as padding. This is why encoded data is 4/3 longer.

Base64 decoding is the inverse process. And as one would expect, the decoded data is 3/4 as long.

While base64 encoding can encode plain text, its real benefit is encoding non-printable characters which may be interpreted by transmitting systems as control characters.

I suggest the original poster render $z as bytes with each bit having meaning to the application. Rendering non-printable characters as text typically invokes Unicode which produces glyphs based on your system's localization.

Base64decode("the answer to life the universe and everything") = 00101010

The easiest way would be to use a GUI:

For Gnome use gnome-schedule (universe)

sudo apt-get install gnome-schedule 

For KDE use kde-config-cron

It should be pre installed on Kubuntu

But if you use a headless linux or don´t want GUI´s you may use:

crontab -e

If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:

*     *     *     *     *  YOURCOMMAND
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- Day in Week (0 to 7) (Sunday is 0 and 7)
|     |     |     +------- Month (1 to 12)
|     |     +--------- Day in Month (1 to 31)
|     +----------- Hour (0 to 23)
+------------- Minute (0 to 59)

There are some shorts, too (if you don´t want the *):

@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year

If you want to use the shorts as cron (because they don´t work or so):

@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *

You can create a variable with an application scope

Just one note I could not find in the answers above. In this code:

context_instance = RequestContext(request)
return render_to_response(template_name, user_context, context_instance)

What the third parameter context_instance actually does? Being RequestContext it sets up some basic context which is then added to user_context. So the template gets this extended context. What variables are added is given by TEMPLATE_CONTEXT_PROCESSORS in settings.py. For instance django.contrib.auth.context_processors.auth adds variable user and variable perm which are then accessible in the template.

I realize that this is an old question but perhaps someone will find my code sample useful. This code encodes a file in Base64 then decodes it and saves it in a new location.

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.Arrays;

import org.apache.commons.codec.binary.Base64;

public class Base64Example {

    public static void main(String[] args) {

        Base64Example tempObject = new Base64Example();

        // convert file to regular byte array
        byte[] codedFile = tempObject.convertFileToByteArray("your_input_file_path");

        // encoded file in Base64
        byte[] encodedFile = Base64.encodeBase64(codedFile);

        // print out the byte array
        System.out.println(Arrays.toString(encodedFile));

        // print the encoded String
        System.out.println(encodedFile);

        // decode file back to regular byte array
        byte[] decodedByteArray = Base64.decodeBase64(encodedFile);

        // save decoded byte array to a file
        boolean success = tempObject.saveFileFromByteArray("your_output_file_path", decodedByteArray);

        // print out success
        System.out.println("success : " + success);
    }

    public byte[] convertFileToByteArray(String filePath) {

        Path path = Paths.get(filePath);

        byte[] codedFile = null;

        try {
            codedFile = Files.readAllBytes(path);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return codedFile;
    }

    public boolean saveFileFromByteArray(String filePath, byte[] decodedByteArray) {

        boolean success = false;

        Path path = Paths.get(filePath);

        try {
            Files.write(path, decodedByteArray);
            success = true;
        } catch (Exception e) {
            e.printStackTrace();
        }

        return success;
    }
}

If you are styling calc in a GWT project, its parser might not parse calc for you as it did not for me... the solution is to wrap it in a css literal like this:

height: literal("-moz-calc(100% - (20px + 30px))");
height: literal("-webkit-calc(100% - (20px + 30px))");
height: literal("calc(100% - (20px + 30px))");

I'd stay well away from using MAC addresses. On some hardware, the MAC address can change when you reboot. We learned quite early during our research not to rely on it.

Take a look at the article Developing for Software Protection and Licensing which has some pointers on how to design & implement apps to reduce piracy.

Obligatory disclaimer & plug: the company I co-founded produces the OffByZero Cobalt licensing solution. So it probably won't surprise you to hear that I recommend outsourcing your licensing, & focusing on your core competencies.

By the looks of it, apart from starting another process, there doesn't seem to be any way of handling a StackOverflowException. Before anyone else asks, I tried using AppDomain, but that didn't work:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading;

namespace StackOverflowExceptionAppDomainTest
{
    class Program
    {
        static void recrusiveAlgorithm()
        {
            recrusiveAlgorithm();
        }
        static void Main(string[] args)
        {
            if(args.Length>0&&args[0]=="--child")
            {
                recrusiveAlgorithm();
            }
            else
            {
                var domain = AppDomain.CreateDomain("Child domain to test StackOverflowException in.");
                domain.ExecuteAssembly(Assembly.GetEntryAssembly().CodeBase, new[] { "--child" });
                domain.UnhandledException += (object sender, UnhandledExceptionEventArgs e) =>
                {
                    Console.WriteLine("Detected unhandled exception: " + e.ExceptionObject.ToString());
                };
                while (true)
                {
                    Console.WriteLine("*");
                    Thread.Sleep(1000);
                }
            }
        }
    }
}

If you do end up using the separate-process solution, however, I would recommend using Process.Exited and Process.StandardOutput and handle the errors yourself, to give your users a better experience.

The basic difference is next() is used for gettting the input till the delimiter is encountered(By default it is whitespace,but you can also change it) and return the token which you have entered.The cursor then remains on the Same line.Whereas in nextLine() it scans the input till we hit enter button and return the whole thing and places the cursor in the next line. **

        Scanner sc=new Scanner(System.in);
        String s[]=new String[2];
        for(int i=0;i<2;i++){
            s[i]=sc.next();
        }
        for(int j=0;j<2;j++)
        {
            System.out.println("The string at position "+j+ " is "+s[j]);
        }

**

Try running this code by giving Input as "Hello World".The scanner reads the input till 'o' and then a delimiter occurs.so s[0] will be "Hello" and cursor will be pointing to the next position after delimiter(that is 'W' in our case),and when s[1] is read it scans the "World" and return it to s[1] as the next complete token(by definition of Scanner).If we use nextLine() instead,it will read the "Hello World" fully and also more till we hit the enter button and store it in s[0]. We may give another string also by using nextLine(). I recommend you to try using this example and more and ask for any clarification.

Extension Method

static class ExceptionHelpers
{
    public static int LineNumber(this Exception ex)
    {
        int n;
        int i = ex.StackTrace.LastIndexOf(" ");
        if (i > -1)
        {
            string s = ex.StackTrace.Substring(i + 1);

{
    //If error in exception LineNumber() will be -1
    System.Diagnostics.Debug.WriteLine("[" + ex.LineNumber() + "] " + ex.Message);

On Vista with virtualization on, the file is here. Note that the AppData folder is hidden. Either show hidden folders, or go straight to it by typing %AppData% in the address bar of Windows Explorer.

Try this way:

<%= f.select(:object_field, ['Item 1', ...], {}, { :class => 'my_style_class' }) %>

select helper takes two options hashes, one for select, and the second for html options. So all you need is to give default empty options as first param after list of items and then add your class to html_options.

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

Best way to convert your string into int is :

 EditText et = (EditText) findViewById(R.id.entry1);
 String hello = et.getText().toString();
 int converted=Integer.parseInt(hello);

To add some explanation to all said before me, I should give you some examples to understand logical concepts.

var name = false || "Mohsen"; # name equals to Mohsen
var family = true || "Alizadeh" # family equals to true

It means if the left side evaluated as a true statement it will be finished and the left side will be returned and assigned to the variable. in other cases the right side will be returned and assigned.

And operator have the opposite structure like below.

var name = false && "Mohsen" # name equals to false
var family = true && "Alizadeh" # family equals to Alizadeh

None of these worked for me but this below worked 100%. Hope this can help others trying to convert it like I was.

CREATE FUNCTION [dbo].[fn_UTC_to_EST]

    @UTC datetime,
    @StandardOffset int
)

    @DST datetime,
    @SSM datetime, -- Second Sunday in March
    @FSN datetime  -- First Sunday in November
-- get DST Range
set @SSM = DATEADD(dd,7 + (6-(DATEDIFF(dd,0,DATEADD(mm,(YEAR(GETDATE())-1900) * 12 + 2,0))%7)),DATEADD(mm,(YEAR(GETDATE())-1900) * 12 + 2,0))+'02:00:00' 
set @FSN = DATEADD(dd, (6-(DATEDIFF(dd,0,DATEADD(mm,(YEAR(GETDATE())-1900) * 12 + 10,0))%7)),DATEADD(mm,(YEAR(GETDATE())-1900) * 12 + 10,0)) +'02:00:00'

-- add an hour to @StandardOffset if @UTC is in DST range
if @UTC between @SSM and @FSN
    set @StandardOffset = @StandardOffset + 1

-- convert to DST
set @DST = dateadd(hour,@StandardOffset,@UTC)

-- return converted datetime
return @DST

END

Why not just add Labels to the top of the Listbox and if changes are needed, the only thing you need to programmatically change are the labels.

this also works:

$url = "http://www.some-url";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xmlresponse = curl_exec($ch);
$xml=simplexml_load_string($xmlresponse);

then I just run a forloop to grab the stuff from the nodes.

like this:`

for($i = 0; $i < 20; $i++) {
$title = $xml->channel->item[$i]->title;
$link = $xml->channel->item[$i]->link;
$desc = $xml->channel->item[$i]->description;
$html .="<div><h3>$title</h3>$link<br />$desc</div><hr>";
}
echo $html;

***note that your node names will differ, obviously..and your HTML might be structured differently...also your loop might be set to higher or lower amount of results.

Provided the char array is null terminated,

char chararray[10] = { 0 };
size_t len = strlen(chararray);

The .NET implementation of UrlEncode does not comply with RFC 3986.

1. Some characters are not encoded but should be. The !()* characters are listed in the RFC's section 2.2 as a reserved characters that must be encoded yet .NET fails to encode these characters.

2. Some characters are encoded but should not be. The .-_ characters are not listed in the RFC's section 2.2 as a reserved character that should not be encoded yet .NET erroneously encodes these characters.

3. The RFC specifies that to be consistent, implementations should use upper-case HEXDIG, where .NET produces lower-case HEXDIG.

I have found a pretty big difference in timing when testing in my browser.

I used the following script:

WARNING: running this will freeze your browser a bit, might even crash it.

var n = 10000000, i;_x000D_
i = n;_x000D_

console.timeEnd('element');

I did 10 million interactions, and those were the results (Chrome 65):

selector: 19591.97509765625ms
element: 4947.8759765625ms

Passing the element directly is around 4 times faster than passing the selector.

I struggled with this on Mac OS X where the find command doesn't support -printf.

A solution that I found, that admittedly relies on the 'group' for all files being 'staff' was...

ls -l -R | sed 's/\(.*\)staff *\([0-9]*\)..............\(.*\)/\2 \3/'

This splits the ls long output into three tokens

1. the stuff before the text 'staff'
2. the file size
3. the file name

And then outputs tokens 2 and 3, i.e. output is number of bytes and then filename

Check out the example from enable-cors.org:

In your ExpressJS app on node.js, do the following with your routes:

app.all('/', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
 });

app.get('/', function(req, res, next) {
  // Handle the get for this route
});

app.post('/', function(req, res, next) {
 // Handle the post for this route
});

The first call (app.all) should be made before all the other routes in your app (or at least the ones you want to be CORS enabled).

[Edit]

If you want the headers to show up for static files as well, try this (make sure it's before the call to use(express.static()):

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
});

I tested this with your code, and got the headers on assets from the public directory:

var express = require('express')
  , app = express.createServer();

app.configure(function () {
    app.use(express.methodOverride());
    app.use(express.bodyParser());
    app.use(function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "X-Requested-With");
      next();
    });
    app.use(app.router);
});

app.configure('development', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});

app.configure('production', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler());
});

app.listen(8888);
console.log('express running at http://localhost:%d', 8888);

You could, of course, package the function up into a module so you can do something like

// cors.js

module.exports = function() {
  return function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
  };
}

// server.js

cors = require('./cors');
app.use(cors());

Tracing the root cause, i finally found that the public key of type dsa is not added to the authorized keys on remote server. Appending the same worked for me.

The ssh was working with rsa key, causing me to look back in my code.

thanks everyone.

Its a little bit not sophisticated but this should work, for example lets say you want to cap your uilabel to 120x120, with max font size of 28:

magicLabel.numberOfLines = 0;
magicLabel.lineBreakMode = NSLineBreakByWordWrapping;
...
magicLabel.text = text;
    for (int i = 28; i>3; i--) {
        CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:(CGFloat)i] constrainedToSize:CGSizeMake(120.0f, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping];
        if (size.height < 120) {
            magicLabel.font = [UIFont systemFontOfSize:(CGFloat)i];
            break;
        }
    }

You are making an ajax request which is asynchronous therefore your console log of the list length occurs before the ajax request has completed.

The only way of achieving what you want is changing the ajax call to be synchronous. You can do this by using the .ajax and passing in asynch : false however this is not recommended as it locks the UI up until the call has returned, if it fails to return the user has to crash out of the browser.

Simple way

<select class ="dropdownstyle" name="category" selected="<?php print($messageeditdetails[0]['category_id']); ?>">

<option value=""><?php echo "Select"; ?></option>

<?php  foreach ($dropdowndetails as $dropdowndetails) { ?>
    <option <?php if($messageeditdetails[0]['category_id'] == $dropdowndetails['id']) { ?> selected="<?php echo $dropdowndetails['id']; ?>" <?php } ?> value="<?php echo $dropdowndetails['id']; ?>"><?php echo $dropdowndetails['category_name']; ?></option>
<?php } ?>
</select>

Either link the shell to an object, have the batch job terminate the shell object (exit) and have the VBA code continue once the shell object = Nothing?

Or have a look at this: Capture output value from a shell command in VBA?

The PrimeFaces ajax events sometimes are very poorly documented, so in most cases you must go to the source code and check yourself.

p:selectOneMenu supports change event:

<p:selectOneMenu ..>
    <p:ajax event="change" update="msgtext"
        listener="#{post.subjectSelectionChanged}" />
    <!--...-->
</p:selectOneMenu>

which triggers listener with AjaxBehaviorEvent as argument in signature:

public void subjectSelectionChanged(final AjaxBehaviorEvent event)  {...}

I've been using path.js for my client side routing. I've found it to be quite succinct and lightweight (it's also been published to NPM too), and makes use of hash based navigation.

Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.

1. Python is dynamically typed: it means that you don't declare a type (e.g. 'integer') for a variable name, and then assign something of that type (and only that type). Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. a = 5 makes the variable name a to refer to the integer 5. Later, a = "hello" makes the variable name a to refer to a string containing "hello". Static typed languages would have you declare int a and then a = 5, but assigning a = "hello" would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.
2. Python is strongly typed. It means that if a = "5" (the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5 to get "hello5".
3. Python is object oriented, with class-based inheritance. Everything is an object (including classes, functions, modules, etc), in the sense that they can be passed around as arguments, have methods and attributes, and so on.
4. Python is multipurpose: it is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It is extended through modules and libraries, that hook very easily into the C programming language.
5. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
6. The code is compiled into byte code and then executed in a virtual machine. This means that precompiled code is portable between platforms.

Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...

Here is example using xargs:

$ xargs -d '\n' -I% sh -c 'echo % | wc -c' < file

getFilesDir()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

Environment.getDataDirectory()

Return the user data directory.

You'll need AJAX if you want to update a part of your page without reloading the entire page.

main cshtml view

<div id="refTable">
     <!-- partial view content will be inserted here -->
</div>

@Html.TextBox("yearSelect3", Convert.ToDateTime(tempItem3.Holiday_date).Year.ToString());
<button id="pY">PrevY</button>

<script>
    $(document).ready(function() {
        $("#pY").on("click", function() {
            var val = $('#yearSelect3').val();
            $.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });
        });
    });
</script>

You'll need to add the fields I have omitted. I've used a <button> instead of submit buttons because you don't have a form (I don't see one in your markup) and you just need them to trigger javascript on the client side.

The HolidayPartialView gets rendered into html and the jquery done callback inserts that html fragment into the refTable div.

HolidayController Update action

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

This controller action takes the year parameter and returns a list of dates using a strongly-typed view model instead of the ViewBag.

view model

public class HolidayViewModel
{
    IEnumerable<DateTime> Dates { get; set; }
}

HolidayPartialView.csthml

@model Your.Namespace.HolidayViewModel;

<table class="tblHoliday">
    @foreach(var date in Model.Dates)
    {
        <tr><td>@date.ToString("MM/dd/yyyy")</td></tr>
    }
</table>

This is the stuff that gets inserted into your div.

For me, I had to remove

<item name="android:gravity">center_vertical</item>

from RelativeLayout, so children's configuration would work:

<item name="android:layout_centerVertical">true</item>

When I try:

<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!"  />

It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.

Pls try:

<script type="text/javascript">
    function moreFields() {
        alert("The text will be show");
    }
</script>

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />

Hope it helped.

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

If you store the padding in resource files, you can simply call

int padding = getResources().getDimensionPixelOffset(R.dimen.padding);

It does the conversion for you.

Thanks so much to John Sansom, his query is terrific !

In addition : you should add " AND PT.ORDINAL_POSITION = CU.ORDINAL_POSITION" at the end of your query.

If you have multiple fields in primary key, this statement will match the corresponding fields to each other (I had the case, your query did create all combinations, so for 2 fields in primary key, I had 4 results for the corresponding foreign key).

(Sorry I can't comment John's answer as I don't have enough reputation points).

My 'hack' solution is

   <div class="col-sm-5">
        <laps
            [lapsData]="rawLapsData"
            [selectedTps]="selectedTps"
            (lapsHandler)="lapsHandler($event)">
        </laps>
    </div>
    <map
        [lapsData]="rawLapsData"
        [selectedTps]="selectedTps"   // <--------
        class="col-sm-7">
    </map>

selectedTps changes at the same time as rawLapsData and that gives map another chance to detect the change through a simpler object primitive type. It is NOT elegant, but it works.

You could use the Firefox add-on User Agent Overrider. With this add-on you can use whatever user agent you want, for examlpe:

Firefox 28/Android: Mozilla/5.0 (Android; Mobile; rv:28.0) Gecko/24.0 Firefox/28.0

If your website detects mobile devices through the user agent then you can test your layout this way.

Update Nov '17:

Due to the release of Firefox 57 and the introduction of web extension this add-on sadly is no longer available. Alternatively you can edit the Firefox preference general.useragent.override in your configuration:

1. In the address bar type about:config
2. Search for general.useragent.override
3. If the preference doesn't exist, right-click on the about:config page, click New, then select String
4. Name the new preference general.useragent.override
5. Set the value to the user agent you want

There might be a fix to <input type="button"> - but if there is, I don't know it.

Otherwise, a good option seems to be to replace it with a carefully styled a element.

Example: http://jsfiddle.net/Uka5v/

.button {
    background-color: #E3E1B8; 
    padding: 2px 4px;
    font: 13px sans-serif;
    text-decoration: none;
    border: 1px solid #000;
    border-color: #aaa #444 #444 #aaa;
    color: #000
}

Upsides include that the a element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)

Context bindings in .NET 3.5 might be just what you're looking for. There are three out of the box: BasicHttpContextBinding, NetTcpContextBinding, and WSHttpContextBinding. Context protocol basically passes key-value pairs in the message header. Check out Managing State With Durable Services article on MSDN magazine.

If your arrays are character arrays(which seems to be the case), You need a strcat().
Your destination array should have enough space to accommodate the appended data though.

In C++, You are much better off using std::string and then you can use std::string::append()

Number of TCP connections will help you. Remember that it is not for a particular database

netstat -a -n | find /c "127.0.0.1:13306"

For Java 7+ doc you can use this:

BufferedReader reader = Files.newBufferedReader(path, StandardCharsets.UTF_8);

Here are all Charsets doc

For example if your file is in CP1252, use this method

Charset.forName("windows-1252");

Here is other canonical names for Java encodings both for IO and NIO doc

If you do not know with exactly encoding you have got in a file, you may use some third-party libs like this tool from Google this which works fairly neat.

One more cause for this:

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

Eg:

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

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

Solution: You should change the URI for either one

Eg:

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

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

Hope it helps some once.

It's not well known that you can also inject a Map of the path variables using the @PathVariable annotation. I'm not sure if this feature is available in Spring 3.0 or if it was added later, but here is another way to solve the example:

@RequestMapping(value={ "/json/{type}", "/json" }, method=RequestMethod.GET)
public @ResponseBody TestBean typedTestBean(
    @PathVariable Map<String, String> pathVariables,
    @RequestParam("track") String track) {

    if (pathVariables.containsKey("type")) {
        return new TestBean(pathVariables.get("type"));
    } else {
        return new TestBean();
    }
}

To convert a string to a number, subtract 0. To convert a number to a string, add "" (the empty string).

5 + 1 will give you 6

(5 + "") + 1 will give you "51"

("5" - 0) + 1 will give you 6

Because font doesn't have color, you need a panel to make a backgound color and give the foreground color for both JLabel (if you use JLabel) and JPanel to make font color, like example below :

JLabel lblusr = new JLabel("User name : ");
lblusr.setForeground(Color.YELLOW);

JPanel usrPanel = new JPanel();
Color maroon = new Color (128, 0, 0);
usrPanel.setBackground(maroon);
usrPanel.setOpaque(true);
usrPanel.setForeground(Color.YELLOW);
usrPanel.add(lblusr);

The background color of label is maroon with yellow font color.

I use openssl, but if you prefer not to, or are on a system (particularly Windows) that doesn't have it, since java 7 in 2011 keytool can do the whole job:

 keytool -printcert -sslserver host[:port] -rfc >tempfile
 keytool -import [-noprompt] -alias nm -keystore file [-storepass pw] [-storetype ty] <tempfile 
 # or with noprompt and storepass (so nothing on stdin besides the cert) piping works:
 keytool -printcert -sslserver host[:port] -rfc | keytool -import -noprompt -alias nm -keystore file -storepass pw [-storetype ty]

Conversely, for java 9 up always, and for earlier versions in many cases, Java can use a PKCS12 file for a keystore instead of the traditional JKS file, and OpenSSL can create a PKCS12 without any assistance from keytool:

openssl s_client -connect host:port </dev/null | openssl pkcs12 -export -nokeys [-name nm] [-passout option] -out p12file
# <NUL on Windows
# default is to prompt for password, but -passout supports several options 
# including actual value, envvar, or file; see the openssl(1ssl) man page 

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on.

See Common Sequence Operations:

Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length.

Also Value Comparisons for further details:

Lexicographical comparison between built-in collections works as follows:

• For two collections to compare equal, they must be of the same type, have the same length, and each pair of corresponding elements must compare equal (for example, [1,2] == (1,2) is false because the type is not the same).
• Collections that support order comparison are ordered the same as their first unequal elements (for example, [1,2,x] <= [1,2,y] has the same value as x <= y). If a corresponding element does not exist, the shorter collection is ordered first (for example, [1,2] < [1,2,3] is true).

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is considered smaller (for example, [1,2] < [1,2,3] returns True).

Note 1: < and > do not mean "smaller than" and "greater than" but "is before" and "is after": so (0, 1) "is before" (1, 0).

Note 2: tuples must not be considered as vectors in a n-dimensional space, compared according to their length.

Note 3: referring to question https://stackoverflow.com/questions/36911617/python-2-tuple-comparison: do not think that a tuple is "greater" than another only if any element of the first is greater than the corresponding one in the second.

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:

• the field's tag is "-", or
• the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.

I had a very similar issue. I got the same error because the csv contained spaces in the header. My csv contained a header "Gender " and I had it listed as:

[['Gender']]

If it's easy enough for you to access your csv, you can use the excel formula trim() to clip any spaces of the cells.

or remove it like this

df.columns = df.columns.to_series().apply(lambda x: x.strip())

]";

foreach (JObject o in a.Children<JObject>())
{
    foreach (JProperty p in o.Properties())
    {
        string name = p.Name;
        string value = (string)p.Value;
        Console.WriteLine(name + " -- " + value);
    }

Got to android/app/build.gradle and search for

 buildTypes {
     ....
 }

You might have something like

buildTypes {
    debug {
        ...
    }
    release {
        ...
    }
    customBuildType {
        ...
    }
}

Chose the buildType you want to start and then start the App the following

react-native run-android --variant=[buildType] --appIdSuffix '[buildType]'

So,

react-native run-android --variant=debug --appIdSuffix 'debug'

echo -n 5a | perl -pe 's/([0-9a-f]{2})/chr hex $1/gie'

Note that this won't skip non-hex characters. If you want just the hex (no whitespace from the original string etc):

echo 5a | perl -ne 's/([0-9a-f]{2})/print chr hex $1/gie'

Also, zsh and bash support this natively in echo:

echo -e '\x5a'

Just press windows button and type %APPDATA% and type enter.

It not only takes arrays of strings, but also can sort by the value of a certain key in an array of objects. It can also automatically identify and sort strings of: currencies, dates, currency, and a bunch of other things.

Surprisingly, it's also only 1.6kB when gzipped.

I experienced the error with python clr running mdx query to Microsoft analytic services using adomd

I solved it with help of Hans Vonn and here is the python version:

clr.AddReference("System.Net")
from System.Net import ServicePointManager, SecurityProtocolType 
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls

following @tony's approach, changed the getTableHeight() function to

<div id="grid1" ui-grid="$ctrl.gridOptions" class="grid" ui-grid-auto-resize style="{{$ctrl.getTableHeight()}}"></div>

getTableHeight() {
    var offsetValue = 365;
    return "height: " + parseInt(window.innerHeight - offsetValue ) + "px!important";
}

the grid would have a dynamic height with regards to window height as well.

window.onload = function() { 
  var txts = document.getElementsByTagName('TEXTAREA'); 

  for(var i = 0, l = txts.length; i < l; i++) {
    if(/^[0-9]+$/.test(txts[i].getAttribute("maxlength"))) { 
      var func = function() { 
        var len = parseInt(this.getAttribute("maxlength"), 10); 

        if(this.value.length > len) { 
          alert('Maximum length exceeded: ' + len); 
          this.value = this.value.substr(0, len); 
          return false; 
        } 
      }

      txts[i].onkeyup = func;
      txts[i].onblur = func;
    } 
  };

}

You can upload up to 8 screenshots. Those screenshots must be one of the dimensions (sizes) you listed; you can have multiple screenshots of the same dimensions.

The ngAfterContentChecked lifecycle hook is triggered when bindings updates for the child components/directives have been already been finished. But you're updating the property that is used as a binding input for the ngClass directive. That is the problem. When Angular runs validation stage it detects that there's a pending update to the properties and throws the error.

To understand the error better, read these two articles:

• Everything you need to know about the ExpressionChangedAfterItHasBeenCheckedError error
• Everything you need to know about change detection in Angular

Think about why you need to change the property in the ngAfterViewInit lifecycle hook. Any other lifecycle that is triggered before ngAfterViewInit/Checked will work, for example ngOnInit or ngDoCheck or ngAfterContentChecked.

So to fix it move renderWidgetInsideWidgetContainer to the ngOnInit() lifecycle hook.

np.isnan can be applied to NumPy arrays of native dtype (such as np.float64):

In [99]: np.isnan(np.array([np.nan, 0], dtype=np.float64))
Out[99]: array([ True, False], dtype=bool)

but raises TypeError when applied to object arrays:

In [96]: np.isnan(np.array([np.nan, 0], dtype=object))
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Since you have Pandas, you could use pd.isnull instead -- it can accept NumPy arrays of object or native dtypes:

In [97]: pd.isnull(np.array([np.nan, 0], dtype=float))
Out[97]: array([ True, False], dtype=bool)

In [98]: pd.isnull(np.array([np.nan, 0], dtype=object))
Out[98]: array([ True, False], dtype=bool)

Note that None is also considered a null value in object arrays.

If this is just a one-off exercise, as an easier alternative, you could apply filters to your source data, and then copy and paste the filtered rows into your new worksheet?

The getRow() method will always yield 0 after a query:

ResultSet.getRow()

Retrieves the current row number.

Second, you output totalrec but never assign anything to it.

If to use for generation of a set of buttons with different parameters of handlers.

JavaScript Closures

let some_button = document.createElement( "button" );
some_button.type = "button";

some_button.onclick = doWithParam( some_param );

function doWithParam( param ){
    return function(){
        alert( param ); // <-- Your code here
    }
}

If we do:

some_button.onclick = foo( some_param );
function foo( param ){
    alert( param );
}

then function foo starts after every updating page.

If we do:

for( let i = 0; i < 10; ++i ){
    var inputElement = document.createElement('input');
    inputElement.type = "button"
    inputElement.addEventListener('click', function(){
        gotoNode(result.name);
    });

 ?   document.body.appendChild(inputElement);?
}

then for all buttons created in the loop, the last value of the parameter is "result.name".

I know this post is old, but what i had to do in the case of the above answers on Linux machine was:

sudo chmod +x directory

May be I am really late for reply, Seriously guys this error resolution took hours of time, i tried every possible solution.

1. installing IIS
2. changing Power Shell from environment variable.
3. Deleting the local group

While, the solution is really really simple. If you look closely in environment variable PSModulePath there will be commas at end of the value simply remove those and enjoy

There's nothing wrong with passing integers to str. One reason you might not do this is that myList is really supposed to be a list of integers e.g. it would be reasonable to sum the values in the list. In that case, do not pass your ints to str before appending them to myList. If you end up not converting to strings before appending, you can construct one big string by doing something like

', '.join(map(str, myList))

You can't resize an image without losing some quality, simply because you are reducing the number of pixels.

Don't reduce the size client side, because browsers don't do a good job of resizing images.

What you can do is programatically change the size before you render it, or as a user uploads it.

Here is an article that explains one way to do this in c#: http://www.codeproject.com/KB/GDI-plus/imageresize.aspx

Although TripleDESCryptoServiceProvider is a safe and good method but it's too slow. If you want to refer to MSDN you will get that advise you to use AES rather TripleDES. Please check below link: http://msdn.microsoft.com/en-us/library/system.security.cryptography.tripledescryptoserviceprovider.aspx you will see this attention in the remark section:

Note A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the AesCryptoServiceProvider class instead of the TripleDESCryptoServiceProvider class. Use TripleDESCryptoServiceProvider only for compatibility with legacy applications and data.

Good luck

For some requirements we might have to skip certain tables. I wrote the below script to add some extra conditions to filter the list of tables. The below script will also display the pre delete count and post delete count.

        IF OBJECT_ID('TEMPDB..#TEMPRECORDCOUNT') IS NOT NULL 
        DROP TABLE #TEMPRECORDCOUNT 

        CREATE TABLE #TEMPRECORDCOUNT 
            (    TABLENAME NVARCHAR(128)
                ,PREDELETECOUNT BIGINT
                ,POSTDELETECOUNT BIGINT
            ) 

        INSERT INTO #TEMPRECORDCOUNT (TABLENAME, PREDELETECOUNT, POSTDELETECOUNT)

        SELECT   O.name TableName
                ,DDPS.ROW_COUNT PREDELETECOUNT
                ,NULL  FROM sys.objects O 

        INNER JOIN (

                    SELECT OBJECT_ID, SUM(row_count) ROW_COUNT 
                    FROM SYS.DM_DB_PARTITION_STATS
                    GROUP BY OBJECT_ID
                   ) DDPS ON DDPS.OBJECT_ID = O.OBJECT_ID
        WHERE O.type = 'U' AND O.name NOT LIKE 'OC%' AND O.schema_id = 1

        DECLARE @TableName NVARCHAR(MAX);
        DECLARE TableDeleteCursor CURSOR FAST_FORWARD 
        FOR 
        SELECT TableName from #TEMPRECORDCOUNT

        OPEN TableDeleteCursor
        FETCH NEXT FROM TableDeleteCursor INTO @TableName

        WHILE (@@FETCH_STATUS <> -1)
        BEGIN
        IF (@@FETCH_STATUS <> -2)
        BEGIN
        DECLARE @STATEMENT NVARCHAR(MAX);

        END
        FETCH NEXT FROM TableDeleteCursor INTO @TableName
        END
        CLOSE TableDeleteCursor
        DEALLOCATE TableDeleteCursor

        UPDATE T

I found it cleaner and more reusable to extend AlertDialog.Builder to create a custom dialog class. This is for a dialog that asks the user to input a phone number. A preset phone number can also be supplied by calling setNumber() before calling show().

InputSenderDialog.java

public class InputSenderDialog extends AlertDialog.Builder {

    public interface InputSenderDialogListener{
        public abstract void onOK(String number);
        public abstract void onCancel(String number);
    }

    private EditText mNumberEdit;

    public InputSenderDialog(Activity activity, final InputSenderDialogListener listener) {
        super( new ContextThemeWrapper(activity, R.style.AppTheme) );

        @SuppressLint("InflateParams") // It's OK to use NULL in an AlertDialog it seems...
        View dialogLayout = LayoutInflater.from(activity).inflate(R.layout.dialog_input_sender_number, null);
        setView(dialogLayout);

        mNumberEdit = dialogLayout.findViewById(R.id.numberEdit);

        setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int id) {
                if( listener != null )
                    listener.onOK(String.valueOf(mNumberEdit.getText()));

            }
        });

        setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int id) {
                if( listener != null )
                    listener.onCancel(String.valueOf(mNumberEdit.getText()));
            }
        });
    }

    public InputSenderDialog setNumber(String number){
        mNumberEdit.setText( number );
        return this;
    }

    @Override
    public AlertDialog show() {
        AlertDialog dialog = super.show();
        Window window = dialog.getWindow();
        if( window != null )
            window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        return dialog;
    }
}

    </EditText>

Usage:

new InputSenderDialog(getActivity(), new InputSenderDialog.InputSenderDialogListener() {
    @Override
    public void onOK(final String number) {
        Log.d(TAG, "The user tapped OK, number is "+number);
    }

    @Override
    public void onCancel(String number) {
        Log.d(TAG, "The user tapped Cancel, number is "+number);
    }
}).setNumber(someNumberVariable).show();

In my case, it was unable to find the .eslintrc file so I copied from node_modules/.bin to root.

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

Take note of all the MainWindow property settings (WindowStartupLocation, SizeToContent and WindowState) - important for this to work correctly - WindowState for my user case requirement was Maximized

I think, that in this case using PYTHONPATH is a better thing, mostly because it doesn't introduce (questionable) unneccessary code.

After all, if you think of it, your user doesn't need that sys.path thing, because your package will get installed into site-packages, because you will be using a packaging system.

If the user chooses to run from a "local copy", as you call it, then I've observed, that the usual practice is to state, that the package needs to be added to PYTHONPATH manually, if used outside the site-packages.

You could use very easily reflection to list all properties, methods and values.

For Gecko based browsers you can use the .toSource() method:

var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;

alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"

But since you use Firebug, why not just use console.log?

this should work just fine if you just need to show what time left, since JavaScript uses frames for its time you'll have get your End Time - The Time RN after that we can divide it by 1000 since apparently 1000 frames = 1 seconds, after that you can use the basic math of time, but there's still a problem to this code, since the calculation is static, it can't compensate for the different day total in a year (360/365/366), the bunch of IF after the calculation is to make it null if the time is lower than 0, hope this helps even though it's not exactly what you're asking :)

var now = new Date();
var end = new Date("End Time");
var total = (end - now) ;
var totalD =  Math.abs(Math.floor(total/1000));

var years = Math.floor(totalD / (365*60*60*24));
var months = Math.floor((totalD - years*365*60*60*24) / (30*60*60*24));
var days = Math.floor((totalD - years*365*60*60*24 - months*30*60*60*24)/ (60*60*24));
var hours = Math.floor((totalD - years*365*60*60*24 - months*30*60*60*24 - days*60*60*24)/ (60*60));
var minutes = Math.floor((totalD - years*365*60*60*24 - months*30*60*60*24 - days*60*60*24 - hours*60*60)/ (60));
var seconds = Math.floor(totalD - years*365*60*60*24 - months*30*60*60*24 - days*60*60*24 - hours*60*60 - minutes*60);

var Y = years < 1 ? "" : years + " Years ";
var M = months < 1 ? "" : months + " Months ";
var D = days < 1 ? "" : days + " Days ";
var H = hours < 1 ? "" : hours + " Hours ";
var I = minutes < 1 ? "" : minutes + " Minutes ";
var S = seconds < 1 ? "" : seconds + " Seconds ";
var A = years == 0 && months == 0 && days == 0 && hours == 0 && minutes == 0 && seconds == 0 ? "Sending" : " Remaining";

document.getElementById('txt').innerHTML = Y + M + D + H + I + S + A;

You can use strtok to get string before first occurence of ?

$url = strtok($_SERVER["REQUEST_URI"], '?');

strtok() represents the most concise technique to directly extract the substring before the ? in the querystring. explode() is less direct because it must produce a potentially two-element array by which the first element must be accessed.

Some other techniques may break when the querystring is missing or potentially mutate other/unintended substrings in the url -- these techniques should be avoided.

A demonstration:

$urls = [
    'www.example.com/myurl.html?unwantedthngs#hastag',
    'www.example.com/myurl.html'
];

foreach ($urls as $url) {
    var_export(['strtok: ', strtok($url, '?')]);
    echo "\n";
    var_export(['strstr/true: ', strstr($url, '?', true)]); // not reliable
    echo "\n";
    var_export(['explode/2: ', explode('?', $url, 2)[0]]);  // limit allows func to stop searching after first encounter
    echo "\n";
    var_export(['substr/strrpos: ', substr($url, 0, strrpos( $url, "?"))]);  // not reliable; still not with strpos()
    echo "\n---\n";
}

Output:

array (
  0 => 'strtok: ',
  1 => 'www.example.com/myurl.html',
)
array (
  0 => 'strstr/true: ',
  1 => 'www.example.com/myurl.html',
)
array (
  0 => 'explode/2: ',
  1 => 'www.example.com/myurl.html',
)
array (
  0 => 'substr/strrpos: ',
  1 => 'www.example.com/myurl.html',
)
---
array (
  0 => 'strtok: ',
  1 => 'www.example.com/myurl.html',
)
array (
  0 => 'strstr/true: ',
  1 => false,                       // bad news
)
array (
  0 => 'explode/2: ',
  1 => 'www.example.com/myurl.html',
)
array (
  0 => 'substr/strrpos: ',
  1 => '',                          // bad news

You can set protocol versions in system property as :

overcome ssl handshake error

System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");

That would be the tempfile module.

It has functions to get the temporary directory, and also has some shortcuts to create temporary files and directories in it, either named or unnamed.

Example:

import tempfile

print tempfile.gettempdir() # prints the current temporary directory

f = tempfile.TemporaryFile()
f.write('something on temporaryfile')
f.seek(0) # return to beginning of file
print f.read() # reads data back from the file
f.close() # temporary file is automatically deleted here

For completeness, here's how it searches for the temporary directory, according to the documentation:

1. The directory named by the TMPDIR environment variable.
2. The directory named by the TEMP environment variable.
3. The directory named by the TMP environment variable.
4. A platform-specific location:
   • On RiscOS, the directory named by the Wimp$ScrapDir environment variable.
   • On Windows, the directories C:\TEMP, C:\TMP, \TEMP, and \TMP, in that order.
   • On all other platforms, the directories /tmp, /var/tmp, and /usr/tmp, in that order.
5. As a last resort, the current working directory.

@Ahmed Elmahy following approach should help you out, when you have got a vector of column names you want to remove from your dataframe:

test_df <- data.frame(col1 = c("a", "b", "c", "d", "e"), col2 = seq(1, 5), col3 = rep(3, 5))
rm_col <- c("col2")
test_df[, !(colnames(test_df) %in% rm_col), drop = FALSE]

Here is my several hours... Reading whole file line by line.

char * readline(FILE *fp, char *buffer)
{

My issue was that I was trying to give my ssh key a SPECIFIC NAME every time I entered ssh-keygen on my mac terminal.

I solved the issue by just leaving the name that "ssh-keygen" generates = id_rsa. You'll end up with 2 keys in your .ssh folder on a mac, id_rsa, which is your private key, and the id_rsa.pub, which is your public key. Then I copied and saved the code from id_rsa.pub into my GitHub account settings, and that was it. Problem solved.

Top level await is not supported. There are a few discussions by the standards committee on why this is, such as this Github issue.

There's also a thinkpiece on Github about why top level await is a bad idea. Specifically he suggests that if you have code like this:

// data.js
const data = await fetch( '/data.json' );
export default data;

Now any file that imports data.js won't execute until the fetch completes, so all of your module loading is now blocked. This makes it very difficult to reason about app module order, since we're used to top level Javascript executing synchronously and predictably. If this were allowed, knowing when a function gets defined becomes tricky.

My perspective is that it's bad practice for your module to have side effects simply by loading it. That means any consumer of your module will get side effects simply by requiring your module. This badly limits where your module can be used. A top level await probably means you're reading from some API or calling to some service at load time. Instead you should just export async functions that consumers can use at their own pace.

I realize there is an accepted answer, and apparently it was either the size of memory chosen or the infinite loop suggestion that solved the issue for the OP.

For me, I added an array to the config file earlier and made some other changes prior to running artisan and getting the out of memory error and no amount of increasing memory helped. What it turned out to be was a missing comma after the array I added to the config file.

I am adding this answer in hopes that it helps someone else figure out what might be causing out of memory error. I am using laravel 5.4 under MAMP.

If you want to do with ImageButton, use the following. It will create round ImageButton with material ripples.

<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_settings_6"
android:background="?selectableItemBackgroundBorderless"
android:padding="10dp"
/>

As @S.Lott says, you should be opening your files in 'rb' mode, not 'rU' mode. However that may NOT be causing your current problem. As far as I know, using 'rU' mode would mess you up if there are embedded \r in the data, but not cause any other dramas. I also note that you have several files (all opened with 'rU' ??) but only one causing a problem.

If the csv module says that you have a "NULL" (silly message, should be "NUL") byte in your file, then you need to check out what is in your file. I would suggest that you do this even if using 'rb' makes the problem go away.

repr() is (or wants to be) your debugging friend. It will show unambiguously what you've got, in a platform independant fashion (which is helpful to helpers who are unaware what od is or does). Do this:

print repr(open('my.csv', 'rb').read(200)) # dump 1st 200 bytes of file

and carefully copy/paste (don't retype) the result into an edit of your question (not into a comment).

Also note that if the file is really dodgy e.g. no \r or \n within reasonable distance from the start of the file, the line number reported by reader.line_num will be (unhelpfully) 1. Find where the first \x00 is (if any) by doing

data = open('my.csv', 'rb').read()
print data.find('\x00')

and make sure that you dump at least that many bytes with repr or od.

What does data.count('\x00') tell you? If there are many, you may want to do something like

for i, c in enumerate(data):
    if c == '\x00':
        print i, repr(data[i-30:i]) + ' *NUL* ' + repr(data[i+1:i+31])

so that you can see the NUL bytes in context.

If you can see \x00 in the output (or \0 in your od -c output), then you definitely have NUL byte(s) in the file, and you will need to do something like this:

fi = open('my.csv', 'rb')
data = fi.read()
fi.close()
fo = open('mynew.csv', 'wb')
fo.write(data.replace('\x00', ''))
fo.close()

By the way, have you looked at the file (including the last few lines) with a text editor? Does it actually look like a reasonable CSV file like the other (no "NULL byte" exception) files?

The answers mentioning canvas.width return the internal dimensions of the canvas, i.e. those specified when creating the element:

<canvas width="500" height="200">

If you size the canvas with CSS, its DOM dimensions are accessible via .scrollWidth and .scrollHeight:

var canvasElem = document.querySelector('canvas');_x000D_
document.querySelector('#dom-dims').innerHTML = 'Canvas DOM element width x height: ' +_x000D_
      canvasElem.scrollWidth +_x000D_
      ' x ' +_x000D_
      canvasElem.scrollHeight_x000D_
_x000D_
var canvasContext = canvasElem.getContext('2d');_x000D_
document.querySelector('#internal-dims').innerHTML = 'Canvas internal width x height: ' +_x000D_
      canvasContext.canvas.width +_x000D_
      ' x ' +_x000D_
      canvasContext.canvas.height;_x000D_
_x000D_
canvasContext.fillStyle = "#00A";_x000D_
canvasContext.fillText("Distorted", 0, 10);

<p id="dom-dims"></p>_x000D_
<p id="internal-dims"></p>_x000D_
<canvas style="width: 100%; height: 123px; border: 1px dashed black">

These guys have an API that will give the results. It's also free to use.

Note: they also provide data source download in xls or sql format at a premium price. but these data also provides technical specifications for all the make model and trim options.

Use the sign of the determinant of vectors (AB,AM), where M(X,Y) is the query point:

position = sign((Bx - Ax) * (Y - Ay) - (By - Ay) * (X - Ax))

It is 0 on the line, and +1 on one side, -1 on the other side.

It should be like import package_name.Class_Name --> If you want to import a specific class (or)

import package_name.* --> To import all classes in a package

user.js is better for customizations as you can include only the lines you want to manipulate, i.e. instead of find-replace you can just overwrite the entire file. Also, prefs.js (at least on Firefox 65.0.1 for Mac) starts with a warning:

// DO NOT EDIT THIS FILE.
//
// If you make changes to this file while the application is running,
// the changes will be overwritten when the application exits.
//
// To change a preference value, you can either:
// - modify it via the UI (e.g. via about:config in the browser); or
// - set it within a user.js file in your profile.

In my case, user.js didn't exist, so I created it and included the line to switch between "No proxy" and "Manual proxy configuration" (I'm using only one SOCKS proxy all the time, so no need to change port number or any other details, just flip 0 to 1 in the following line):

user_pref("network.proxy.type", 1);

I ended up with a bash script that I placed at /usr/local/bin/firefox:

#!/bin/bash
if [ $# -eq 0 ]; then
  echo 'user_pref("network.proxy.type", 0);' > ~/Library/Application\ Support/Firefox/Profiles/t5rvw47o.default/user.js
  open -a Firefox
else
  case $1 in
    vpn)
      echo 'user_pref("network.proxy.type", 1);' > ~/Library/Application\ Support/Firefox/Profiles/t5rvw47o.default/user.js
      open -a Firefox
  esac 
fi

To use it, I make sure no Firefox is running and then run firefox to have a straight connection and firefox vpn to use proxy.

I also faced the same error msg, so i tried ng serve --port 12012 and it worked fine.

To subset by column index (to avoid typing their names) you can do

dt[, .SD, .SDcols = -c(1:3, 5L)]

result seems ok

Alternatively to what the others are correctly suggesting, I find it easier usually to toggle CSS classes, instead of individual CSS settings (especially background image URLs). For example:

// in CSS 
.bg1 
{
  background-image: url(/some/image/url/here.jpg);
}

.bg2 
{
  background-image: url(/another/image/url/there.jpg);
}

// in JS
// based on value of imageUrl, determine what class to remove and what class to add.
$('myOjbect').removeClass('bg1').addClass('bg2');

You can use both jquery and javascript method: if you have two images for example:

<img class="image1" src="image1.jpg" alt="image">
<img class="image2" src="image2.jpg" alt="image">

1)Jquery Method->

$(".image2").attr("src","image1.jpg");

2)Javascript Method->

var image = document.getElementsByClassName("image2");
image.src = "image1.jpg"

For this type of issue jquery is the simple one to use.

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

Also faced the same problem when using unmanaged c/c++ dll file in c# environment.

1.Checked the compatibility of dll with 32bit or 64bit CPU.

2.Checked the correct paths of DLL .bin folder, system32/sysWOW64 , or given path.

3.Checked if PDB(Programme Database) files are missing.This video gives you ans best undestand about pdb files.

When running 32-bit C/C++ binary code in 64bit system, could arise this because of platform incompatibility. You can change it from Build>Configuration manager.

looking at your error message first of all I would suggest you to recompile your whole application, make sure all the required dlls are there in bin folder when you recompile it.

Arrays are special objects in java, they have a simple attribute named length which is final.

There is no "class definition" of an array (you can't find it in any .class file), they're a part of the language itself.

10.7. Array Members

The members of an array type are all of the following:

• The public final field length, which contains the number of components of the array. length may be positive or zero.

• The public method clone, which overrides the method of the same name in class Object and throws no checked exceptions. The return type of the clone method of an array type T[] is T[].

  A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Subarrays are shared.

• All the members inherited from class Object; the only method of Object that is not inherited is its clone method.

Resources:

• JLS - Arrays

I had to re-run ng update @angular/cli for angular-cli.json to be changed to angular.json

VueJS can't pickup your changes to the state if you manipulate arrays like this.

As explained in Common Beginner Gotchas, you should use array methods like push, splice or whatever and never modify the indexes like this a[2] = 2 nor the .length property of an array.

For what you are trying to do, this should work. \K resets the starting point of the match.

You can do the same for getting your Security ID matches.

Go through http://www.w3.org/TR/css3-fonts/

Try this:

  @font-face {
        font-family: 'EntezareZohoor2';
        src: url('EntezareZohoor2.eot');
        src: local('EntezareZohoor2'), local('EntezareZohoor2'), url('EntezareZohoor2.ttf') format('svg');
       font-weight: normal;
       font-style: normal;

Making a function static hides it from other translation units, which helps provide encapsulation.

helper_file.c

int f1(int);        /* prototype */
static int f2(int); /* prototype */

int f1(int foo) {
    return f2(foo); /* ok, f2 is in the same translation unit */
                    /* (basically same .c file) as f1         */
}

int f2(int foo) {
    return 42 + foo;
}

main.c:

int f1(int); /* prototype */
int f2(int); /* prototype */

int main(void) {
    f1(10); /* ok, f1 is visible to the linker */
    f2(12); /* nope, f2 is not visible to the linker */
    return 0;
}

Here's another way to do it without using external libraries:

import java.io.File;
import java.io.FileReader;
import java.io.IOException;

match is much faster than search, so instead of doing regex.search("word") you can do regex.match((.*?)word(.*?)) and gain tons of performance if you are working with millions of samples.

This comment from @ivan_bilan under the accepted answer above got me thinking if such hack is actually speeding anything up, so let's find out how many tons of performance you will really gain.

I prepared the following test suite:

import random
import re
import string
import time

LENGTH = 10
LIST_SIZE = 1000000

def generate_word():
    word = [random.choice(string.ascii_lowercase) for _ in range(LENGTH)]
    word = ''.join(word)
    return word

wordlist = [generate_word() for _ in range(LIST_SIZE)]

start = time.time()
[re.search('python', word) for word in wordlist]
print('search:', time.time() - start)

start = time.time()
[re.match('(.*?)python(.*?)', word) for word in wordlist]
print('match:', time.time() - start)

I made 10 measurements (1M, 2M, ..., 10M words) which gave me the following plot:

The resulting lines are surprisingly (actually not that surprisingly) straight. And the search function is (slightly) faster given this specific pattern combination. The moral of this test: Avoid overoptimizing your code.

You may use 'inf' like this:

import math
bool_true = 0 < math.inf
bool_false = 0 < -math.inf

Refer: math — Mathematical functions

The way I resolved it is by using Fragments. These are backwards compatible until API 4 by using the support library.

You make a "wrapper" layout with a FrameLayout in it.

Example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:orientation="vertical" >

     <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/fragment_container"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
</LinearLayout>

Then you make a FragmentActivity in wich you can replace the FrameLayout any time you want.

Example:

public class SampleFragmentActivity extends FragmentActivity
{

     @Override
 public void onCreate(Bundle savedInstanceState)
 {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.wrapper);

    // Check that the activity is using the layout version with
    // the fragment_container FrameLayout
    if (findViewById(R.id.fragment_container) != null)
    {

        // However, if we're being restored from a previous state,
        // then we don't need to do anything and should return or else
        // we could end up with overlapping fragments.
        if (savedInstanceState != null)
        {
            return;
        }
        updateLayout();
     }
  }

  private void updateLayout()
  {
     Fragment fragment = new SampleFragment();
     fragment.setArguments(getIntent().getExtras());

     // replace original fragment by new fragment
     getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, fragment).commit();
  }

In the Fragment you inflate/replace you can use the onStart and onCreateView like you normaly would use the onCreate of an activity.

Example:

public class SampleFragment extends Fragment
{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        return inflater.inflate(R.layout.yourActualLayout, container, false);
    }

    @Override
    public void onStart()
    {
        // do something with the components, or not!
        TextView text = (TextView) getActivity().findViewById(R.id.text1);

        super.onStart();
    }
}

in my case (the website SSL uses ev curves) the issue with the SSL was solved by adding this option ecdhCurve: 'P-521:P-384:P-256'

request({ url, 
   agentOptions: { ecdhCurve: 'P-521:P-384:P-256', }
}, (err,res,body) => {
...

JFYI, maybe this will help someone

by using Listbuffer we can save data into single file:

import java.io.FileWriter
import org.apache.spark.sql.SparkSession
import scala.collection.mutable.ListBuffer
    val text = spark.read.textFile("filepath")
    var data = ListBuffer[String]()
    for(line:String <- text.collect()){
      data += line
    }
    val writer = new FileWriter("filepath")
    data.foreach(line => writer.write(line.toString+"\n"))
    writer.close()

Adding a new answer just as a reference for future researchers and as nobody mentioned that yet I think it's valid.

Another good option is ng-grid http://angular-ui.github.io/ng-grid/.

And there's a beta version (http://ui-grid.info/) available already with some improvements:

• Native AngularJS implementation, no jQuery
• Performs well with large data sets; even 10,000+ rows
• Plugin architecture allows you to use only the features you need

UPDATE:

It seems UI GRID is not beta anymore.

With the 3.0 release, the repository has been renamed from "ng-grid" to "ui-grid".

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv) {
  int i, parameter = 0;
  if (argc >= 2) {
    /* there is 1 parameter (or more) in the command line used */
    /* argv[0] may point to the program name */
    /* argv[1] points to the 1st parameter */
    /* argv[argc] is NULL */
    parameter = atoi(argv[1]); /* better to use strtol */
    if (parameter > 0) {
      for (i = 0; i < parameter; i++) printf("%d ", i);
    } else {
      fprintf(stderr, "Please use a positive integer.\n");
    }
  }
  return 0;
}

As others have pointed out one could just delete all the files in the repo and then check them out. I prefer this method and it can be done with the code below

git ls-files -z | xargs -0 rm
git checkout -- .

or one line

git ls-files -z | xargs -0 rm ; git checkout -- .

I use it all the time and haven't found any down sides yet!

For some further explanation, the -z appends a null character onto the end of each entry output by ls-files, and the -0 tells xargs to delimit the output it was receiving by those null characters.

You can use getSubtype() for more details. Check out slide 9 here: http://dl.google.com/io/2009/pres/W_0300_CodingforLife-BatteryLifeThatIs.pdf

ConnectivityManager mConnectivity = null;
TelephonyManager mTelephony = null;
// Skip if no connection, or background data disabled
NetworkInfo info = mConnectivity.getActiveNetworkInfo();
if (info == null || !mConnectivity.getBackgroundDataSetting()) {
    return false;
}

// Only update if WiFi or 3G is connected and not roaming
int netType = info.getType();
int netSubtype = info.getSubtype();
if (netType == ConnectivityManager.TYPE_WIFI) {
    return info.isConnected();
} else if (netType == ConnectivityManager.TYPE_MOBILE
    && netSubtype == TelephonyManager.NETWORK_TYPE_UMTS
    && !mTelephony.isNetworkRoaming()) {
        return info.isConnected();
} else {
    return false;
}

Also, please check out Emil's answer for a more detailed dive into this.

If you have python, you can use a package called iis_bridge that solves the problem. To install:

pip install iis_bridge

then in the python console:

import iis_bridge as iis
iis.install()

There is no "better" but the more common one is ||. They have different precedence and || would work like one would expect normally.

See also: Logical operators (the following example is taken from there):

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

Or a 1-liner:

perl -p -i -e 's/\r\n$/\n/g' file1.txt file2.txt ... filen.txt

When in doubt, follow MVC conventions.

Create a viewModel if you haven't already that contains a property for JobID

public class Model
{
     public string JobId {get; set;}
     public IEnumerable<MyCurrentModel> myCurrentModel { get; set; }
     //...any other properties you may need
}

Strongly type your view

@model Fully.Qualified.Path.To.Model

Add a hidden field for JobId to the form

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post))
{   
    //...    
    @Html.HiddenFor(m => m.JobId)
}

And accept the model as the parameter in your controller action:

[HttpPost]
public FileStreamResult myMethod(Model model)
{
    sting str = model.JobId;
}

// copy /tmp/abc.txt to /tmp/abc.txt (target path)

// username and password of 10.1.1.2 is "username" and "password"

sshpass -p "password" scp /tmp/abc.txt [email protected]:/tmp/abc.txt

// install sshpass (ubuntu)

sudo apt-get install sshpass

Daniel Imms answer is excellent in regards to applying your CSS rotation to an inner element. However, it is possible to accomplish the end goal in a way that does not require JavaScript and works with longer strings of text.

Typically the whole reason to have vertical text in the first table column is to fit a long line of text in a short horizontal space and to go alongside tall rows of content (as in your example) or multiple rows of content (which I'll use in this example).

By using the ".rotate" class on the parent TD tag, we can not only rotate the inner DIV, but we can also set a few CSS properties on the parent TD tag that will force all of the text to stay on one line and keep the width to 1.5em. Then we can use some negative margins on the inner DIV to make sure that it centers nicely.

td {_x000D_
    border: 1px black solid;_x000D_
    padding: 5px;_x000D_

One thing to keep in mind with this solution is that it does not work well if the height of the row (or spanned rows) is shorter than the vertical text in the first column. It works best if you're spanning multiple rows or you have a lot of content creating tall rows.

Have fun playing around with this on jsFiddle.

Why do you need to state both 'x' and 'y' before the ':'?

You could actually in some situations(when you have only one argument) do not put the x and y before ":".

>>> flist = []
>>> for i in range(3):
...     flist.append(lambda : i)

but the i in the lambda will be bound by name, so,

>>> flist[0]()
2
>>> flist[2]()
2
>>>

different from what you may want.

An easier solution is to use the user:pass@host format directly in the URL.

Using the request library:

var request = require('request'),
    username = "john",
    password = "1234",
    url = "http://" + username + ":" + password + "@www.example.com";

request(
    {
        url : url
    },
    function (error, response, body) {
        // Do more stuff with 'body' here
    }
);

I've written a little blogpost about this as well.

In general you must be absolutely certain that you are meeting all of the requirements for making the reference - I know it's the obvious answer, but you're probably overlooking a relatively simple requirement.

The following code:

(function () {

})();

is called an immediately invoked function expression (IIFE).

It is called a function expression because the ( yourcode ) operator in Javascript force it into an expression. The difference between a function expression and a function declaration is the following:

// declaration:
function declaredFunction () {}

// expressions:

// storing function into variable
const expressedFunction = function () {}

// Using () operator, which transforms the function into an expression
(function () {})

An expression is simply a bunch of code which can be evaluated to a single value. In case of the expressions in the above example this value was a single function object.

After we have an expression which evaluates to a function object we then can immediately invoke the function object with the () operator. For example:

(function() {_x000D_
_x000D_
  const foo = 10;        // all variables inside here are scoped to the function block_x000D_
  console.log(foo);_x000D_
_x000D_
})();_x000D_
_x000D_
console.log(foo);  // referenceError foo is scoped to the IIFE

Why is this useful?

When we are dealing with a large code base and/or when we are importing various libraries the chance of naming conflicts increases. When we are writing certain parts of our code which is related (and thus is using the same variables) inside an IIFE all of the variables and function names are scoped to the function brackets of the IIFE. This reduces chances of naming conflicts and lets you name them more careless (e.g. you don't have to prefix them).

In jquery you can easily set hover pseudo classes.

$("p").hover(function(){
$(this).css("background-color", "yellow");
}, function(){
$(this).css("background-color", "pink");
});

I understand you want to download an older version via the BitBucket web interface without using a Mercurial/Git client.

Check this related question. On the comments, someone says that there is no way to do that. Fortunately, that's not entirely true.

By navigating on BitBucket project pages, I found no link to download an arbitrary version. There are links to download specific tags, in the format:

https://bitbucket.org/owner/repository/get/v0.1.2.tar.gz

But by tweaking a bit the url above, changing the tag name by the commit hash, like:

https://bitbucket.org/owner/repository/get/A0B1C2D.tar.gz

You can actually download a specific version.

As mentioned by Rakka Rage in a comment, replacing .tar.gz by .zip works too.

By setting script tag type other than text/javascript, browser will not execute the internal code of script tag. This is called micro template. This concept is widely used in Single page application(aka SPA).

<script type="text/template">I am a Micro template. 
  I am going to make your web page faster.</script>

For micro template, type of the script tag is text/template. It is very well explained by Jquery creator John Resig http://ejohn.org/blog/javascript-micro-templating/

Try this: sudo systemctl start mongod and to check whether its running use sudo systemctl status mongod

Try this

$('#something_clickable').on('click', function () {
  $("#my_modal").modal("hide");
  $("body").removeClass("modal-open");
  $('.modal-backdrop').remove();
 });

It works fine for me.

Ways to hide Navigation Bar in Swift:

self.navigationController?.setNavigationBarHidden(true, animated: true)
self.navigationController?.navigationBar.isHidden = true
self.navigationController?.isNavigationBarHidden = true

You can accomplish this with jquery.

Place this code in index.html

<html>
<head>
<title></title>
<script
    src="https://code.jquery.com/jquery-3.3.1.js"
    integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60="
    crossorigin="anonymous">
</script>
<script> 
$(function(){
  $("#header").load("header.html"); 
  $("#footer").load("footer.html"); 
});
</script> 
</head>
<body>
<div id="header"></div>
<!--Remaining section-->
<div id="footer"></div>
</body>
</html>

and put this code in header.html and footer.html, at the same location as index.html

<a href="http://www.google.com">click here for google</a>

Now, when you visit index.html, you should be able to click the link tags.

Copy the below script "ez_setup.py" from the below URL

https://bootstrap.pypa.io/ez_setup.py

And copy it into your Python location

C:\Python27>

Run the command

C:\Python27? python ez_setup.py

This will install the easy_install under Scripts directory

C:\Python27\Scripts

Run easy install from the Scripts directory >

C:\Python27\Scripts> easy_install

Clone the container object and write 2 letters and calculate the height. This return the real height with all style applied, line height, etc. Now, calculate the height object / the size of a letter. In Jquery, the height excelude the padding, margin and border, it is great to calculate the real height of each line:

other = obj.clone();
other.html('a<br>b').hide().appendTo('body');
size = other.height() / 2;
other.remove();
lines = obj.height() /  size;

If you use a rare font with different height of each letter, this does not works. But works with all normal fonts, like Arial, mono, comics, Verdana, etc. Test with your font.

Example:

<div id="content" style="width: 100px">hello how are you? hello how are you? hello how are you?</div>
<script type="text/javascript">
$(document).ready(function(){

  calculate = function(obj){
    other = obj.clone();
    other.html('a<br>b').hide().appendTo('body');
    size = other.height() / 2;
    other.remove();
    return obj.height() /  size;
  }

  n = calculate($('#content'));
  alert(n + ' lines');
});
</script>

Result: 6 Lines

Works in all browser without rare functions out of standards.

I think you need to do is to transform your data from object not to JSON string, but to url params.

From Ben Nadel's blog.

By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".

Example from here.

$http({
    method: 'POST',
    url: url,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
        return str.join("&");
    },
    data: {username: $scope.userName, password: $scope.password}
}).then(function () {});

UPDATE

To use new services added with AngularJS V1.4, see

• URL-encoding variables using only AngularJS services

For above v4

$('#yourselect').on("select2:select", function(e) { 
     // after selection of select2 
});

Following the solution here http://jsfiddle.net/dRbe4/,

<div class="row">
    <div class="col-lg-3 fixed">
        Fixed content
    </div>
    <div class="col-lg-9 scrollit">
        Normal scrollable content
    </div>

 </div>

I modified some css to work just perfect:

.fixed {
        position: fixed;
        width: 25%;
}
.scrollit {
        float: left;
        width: 71%
}

Thanks @Lowkase for sharing the solution.

On macOS 10.13.6 with MongoDB 4.0

I was unable to connect to localhost from the mongo shell

I started MongoDB with:

mongod --config /usr/local/etc/mongod.conf

I found that the 'mongod.conf' had:

bindIp: 127.0.0.1

Change my JavaScript connection from localhost to 127.0.0.1 and it worked fine.

The same was occurring with MongoDB Compass too.

Try out this

var str ="{ "name" : "user"}";
var jsonData = JSON.parse(str);     
console.log(jsonData.name)

//Array Object

str ="[{ "name" : "user"},{ "name" : "user2"}]";
jsonData = JSON.parse(str);     
console.log(jsonData[0].name)

It is called the ternary operator

tmp = (foo==1 ? true : false);

Use rand(5) to randomly fill each bit with 0 or 1.
For e.g: call rand(5) and

if the result is 1 or 2, fill the bit with 0
if the result is 4 or 5, fill the bit with 1
if the result is 3 , then ignore and do it again (rejection)

This way we can fill 3 bits randomly with 0/1 and thus get a number from 1-7.

EDIT: This seems like the simplest and most efficient answer, so here's some code for it:

public static int random_7() {
    int returnValue = 0;
    while (returnValue == 0) {
        for (int i = 1; i <= 3; i++) {
            returnValue = (returnValue << 1) + random_5_output_2();
        }
    }
    return returnValue;
}

private static int random_5_output_2() {
    while (true) {
        int flip = random_5();

        if (flip < 3) {
            return 0;
        }
        else if (flip > 3) {
            return 1;
        }
    }
}

If you want to use default value for a DateTime parameter in a method, you can only use default(DateTime).

The following line will not compile:

    private void MyMethod(DateTime syncedTime = DateTime.MinValue)

This line will compile:

    private void MyMethod(DateTime syncedTime = default(DateTime))

I use to throw an exception in the base class.

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

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

Very easy:

1. you have only to place the iframe between

    <center> ...  </center>
   

2. with some

    <br>
   

. That's all.

final Map<String, String> mss1 = new ProcessBuilder().environment();
mss1.entrySet()
        .stream()
        //depending on how you want to join K and V use different delimiter
        .map(entry -> 
        String.join(":", entry.getKey(),entry.getValue()))
        .forEach(System.out::println);

You're population is from the server-side. Using the registerclientscript will put the script at the beginning of the form.. you'll want to use RegisterStartupScript(Block) to have the script placed at the end of the page in question.

The former tries to run the script before the text area exists in the dom, the latter will run the script after that element in the page is created.

Using the angular.module API with an array at the end will tell angular to create a new module:

myApp.js

// It is like saying "create a new module"
angular.module('myApp.controllers', []); // Notice the empty array at the end here

Using it without the array is actually a getter function. So to seperate your controllers, you can do:

Ctrl1.js

// It is just like saying "get this module and create a controller"
angular.module('myApp.controllers').controller('Ctrlr1', ['$scope', '$http', function($scope, $http) {}]);

Ctrl2.js

angular.module('myApp.controllers').controller('Ctrlr2', ['$scope', '$http', function($scope, $http) {}]);

During your javascript imports, just make sure myApp.js is after AngularJS but before any controllers / services / etc...otherwise angular won't be able to initialize your controllers.

I tried doing a SELECT DATE(ColumnName), however this does not work for TIMESTAMP columns^† because they are stored in UTC and the UTC date is used instead of converting to the local date. I needed to select rows that were on a specific date in my time zone, so combining my answer to this other question with Balaswamy Vaddeman's answer to this question, this is what I did:

If you are storing dates as DATETIME

Just do SELECT DATE(ColumnName)

If you are storing dates as TIMESTAMP

Load the time zone data into MySQL if you haven't done so already. For Windows servers see the previous link. For Linux, FreeBSD, Solaris, and OS X servers you would do:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

Then format your query like this:

SELECT DATE(CONVERT_TZ(`ColumnName`, 'UTC', 'America/New_York'))

You can also put this in the WHERE part of the query like this (but note that indexes on that column will not work):

SELECT * FROM tableName
WHERE DATE(CONVERT_TZ(`ColumnName`, 'UTC', 'America/New_York')) >= '2015-02-04'

(Obviously substitute America/New_York for your local time zone.)

† The only exception to this is if your local time zone is GMT and you don't do daylight savings because your local time is the same as UTC.

for c in np.hsplit(array, array.shape[1]):
    some_fun(c)

I would like to suggest you the JQuery option.

$("#item").toggle();
$("#item").hide();
$("#item").show();

For example:

$(document).ready(function(){
   $("#item").click(function(event){
     //Your actions here
   });
 });

Looking at the source code for dumpsys and service, you can get the list of services available by executing the following:

adb shell service -l

You can then supply the service name you are interested in to dumpsys to get the specific information. For example (note that not all services provide dump info):

adb shell dumpsys activity
adb shell dumpsys cpuinfo
adb shell dumpsys battery

As you can see in the code (and in K_Anas's answer), if you call dumpsys without any service name, it will dump the info on all services in one big dump:

adb shell dumpsys

Some services can receive additional arguments on what to show which normally is explained if you supplied a -h argument, for example:

adb shell dumpsys activity -h
adb shell dumpsys window -h
adb shell dumpsys meminfo -h
adb shell dumpsys package -h
adb shell dumpsys batteryinfo -h

If the goal simply is to list all computer objects with an empty description attribute try this

import-module activedirectory  
$domain = "domain.example.com" 
Get-ADComputer -Filter '*' -Properties Description | where { $_.Description -eq $null }

$query = mysql_query("SELECT username FROM Users WHERE username='$username' ")

Use prepared statements, do not use mysql as it is deprecated.

// check if name is taken already
$stmt = $link->prepare("SELECT username FROM users WHERE username = :username");
$stmt->execute([
    'username' => $username
]);
$user = $stmt->fetch(PDO::FETCH_ASSOC);

if (isset($user) && !empty($user)){
    // Username already taken
}

In C++ you would use std::find, and check if the resultant pointer points to the end of the range, like this:

Foo array[10];
... // Init the array here
Foo *foo = std::find(std::begin(array), std::end(array), someObject);
// When the element is not found, std::find returns the end of the range
if (foo != std::end(array)) {
    cerr << "Found at position " << std::distance(array, foo) << endl;
} else {
    cerr << "Not found" << endl;
}

Note that reversing the whole string (either with the rbegin()/rend() range constructor or with std::reverse) and comparing it with the input would perform unnecessary work.

It's sufficient to compare the first half of the string with the latter half, in reverse:

#include <string>
#include <algorithm>
#include <iostream>
int main()
{
    std::string s;
    std::cin >> s;
    if( equal(s.begin(), s.begin() + s.size()/2, s.rbegin()) )
        std::cout << "is a palindrome.\n";
    else
        std::cout << "is NOT a palindrome.\n";
}

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

You can use ORDER BY clause to sort data rows by values in columns. Something like

=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C, D")

If you’d like to order by some columns descending, others ascending, you can add desc/asc, ie:

=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C desc, D")

SELECT * FROM table WHERE field1 NOT LIKE '%$x%'; (Make sure you escape $x properly beforehand to avoid SQL injection)

Edit: NOT IN does something a bit different - your question isn't totally clear so pick which one to use. LIKE 'xxx%' can use an index. LIKE '%xxx' or LIKE '%xxx%' can't.

Assuming your stream is not backed by a socket (so you can't use Socket.setSoTimeout()), I think the standard way of solving this type of problem is to use a Future.

Suppose I have the following executor and streams:

    ExecutorService executor = Executors.newFixedThreadPool(2);
    final PipedOutputStream outputStream = new PipedOutputStream();
    final PipedInputStream inputStream = new PipedInputStream(outputStream);

I have writer that writes some data then waits for 5 seconds before writing the last piece of data and closing the stream:

    Runnable writeTask = new Runnable() {
        @Override
        public void run() {
            try {
                outputStream.write(1);
                outputStream.write(2);
                Thread.sleep(5000);
                outputStream.write(3);
                outputStream.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
    executor.submit(writeTask);

The normal way of reading this is as follows. The read will block indefinitely for data and so this completes in 5s:

    long start = currentTimeMillis();
    int readByte = 1;
    // Read data without timeout
    while (readByte >= 0) {
        readByte = inputStream.read();
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }
    System.out.println("Complete in " + (currentTimeMillis() - start) + "ms");

which outputs:

Read: 1
Read: 2
Read: 3
Complete in 5001ms

If there was a more fundamental problem, like the writer not responding, the reader would block for ever. If I wrap the read in a future, I can then control the timeout as follows:

    int readByte = 1;
    // Read data with timeout
    Callable<Integer> readTask = new Callable<Integer>() {
        @Override
        public Integer call() throws Exception {
            return inputStream.read();
        }
    };
    while (readByte >= 0) {
        Future<Integer> future = executor.submit(readTask);
        readByte = future.get(1000, TimeUnit.MILLISECONDS);
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }

which outputs:

Read: 1
Read: 2
Exception in thread "main" java.util.concurrent.TimeoutException
    at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:228)
    at java.util.concurrent.FutureTask.get(FutureTask.java:91)
    at test.InputStreamWithTimeoutTest.main(InputStreamWithTimeoutTest.java:74)

I can catch the TimeoutException and do whatever cleanup I want.

If the string is empty, comboBox.getSelectedItem().toString() will give a NullPointerException. So better to typecast by (String).

If you're happy with the Effective Java implementation recommended by dmeister, you can use a library call instead of rolling your own:

@Override
public int hashCode() {
    return Objects.hashCode(this.firstName, this.lastName);
}

This requires either Guava (com.google.common.base.Objects.hashCode) or the standard library in Java 7 (java.util.Objects.hash) but works the same way.

It is not working. The PHP session will expire anyway after 1440 seconds.

Change in PHP.ini this too:

session.gc_maxlifetime = 3600

http://www.phpmyadmin.net/documentation/Documentation.html#config

Also, from PHP.ini:

If you are using the subdirectory option for storing session files

; (see session.save_path above), then garbage collection does not

; happen automatically. You will need to do your own garbage

; collection through a shell script, cron entry, or some other method.

; For example, the following script would is the equivalent of

; setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):

; cd /path/to/sessions; find -cmin +24 | xargs rm

if(isset($rule["type"]) && ($rule["type"] == "radio") || ($rule["type"] == "checkbox") )
{
    if(!isset($data[$field]))
        $data[$field]="";
}

Just pass var2 as an extra argument to one of the apply functions.

mylist <- list(a=1,b=2,c=3)
myfxn <- function(var1,var2){
  var1*var2
}
var2 <- 2

sapply(mylist,myfxn,var2=var2)

This passes the same var2 to every call of myfxn. If instead you want each call of myfxn to get the 1st/2nd/3rd/etc. element of both mylist and var2, then you're in mapply's domain.

Correct way described in this answer: https://stackoverflow.com/a/52772444/2519714 Most popular answer at current moment is not totally correct.

This way https://stackoverflow.com/a/24838367/2519714 is not correct in some cases like: sub select has where bindings, then joining table to sub select, then other wheres added to all query. For example query: select * from (select * from t1 where col1 = ?) join t2 on col1 = col2 and col3 = ? where t2.col4 = ? To make this query you will write code like:

$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->from(DB::raw('('. $subQuery->toSql() . ') AS subquery'))
    ->mergeBindings($subQuery->getBindings());
$query->join('t2', function(JoinClause $join) {
    $join->on('subquery.col1', 't2.col2');
    $join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');

During executing this query, his method $query->getBindings() will return bindings in incorrect order like ['val3', 'val1', 'val4'] in this case instead correct ['val1', 'val3', 'val4'] for raw sql described above.

One more time correct way to do this:

$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->fromSub($subQuery, 'subquery');
$query->join('t2', function(JoinClause $join) {
    $join->on('subquery.col1', 't2.col2');
    $join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');

Also bindings will be automatically and correctly merged to new query.

This approach seems more straightforward, avoiding the need to individually select each file:

# keep remote files
git merge --strategy-option theirs
# keep local files
git merge --strategy-option ours

or

# keep remote files
git pull -Xtheirs
# keep local files
git pull -Xours
