Programs & Examples On #Size type

Look in your configuration file and search for the error_log setting. Or use phpinfo() to find this setting.

<form onSubmit="return captureForm()"> that should do. Make sure that your captureForm() method returns false.

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

Yes. For that ensure that you declare the worksheet

For example

Previous Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet3")

    Debug.Print ws.Cells(23, 4).Value
End Sub

New Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet4")

    Debug.Print ws.Cells(23, 4).Value
End Sub

The CASE and ORDER BY suggestions should all work, but I'm going to suggest a horse of a different color. Assuming that there are only a reasonable number of values for x_field and you already know what they are, create an enumerated type with F, P, A, and I as the values (plus whatever other possible values apply). Enums will sort in the order implied by their CREATE statement. Also, you can use meaninful value names—your real application probably does and you have just masked them for confidentiality—without wasted space, since only the ordinal position is stored.

It seems some what center of the screen. So I would like to do like this

body { 
     background: url('http://oi44.tinypic.com/33tjudk.jpg') no-repeat center center fixed;    
     background-size:cover; 
     text-align: 0 auto; // Make the play button horizontal center
}

#play_button {
    position:absolute;  // absolutely positioned
    transition: .5s ease;
    top: 50%;  // Makes vertical center
} 

You can use npm-prune to remove extraneous packages.

npm prune [[<@scope>/]<pkg>...] [--production] [--dry-run] [--json]

This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.

Extraneous packages are packages that are not listed on the parent package's dependencies list.

If the --production flag is specified or the NODE_ENV environment variable is set to production, this command will remove the packages specified in your devDependencies. Setting --no-production will negate NODE_ENV being set to production.

If the --dry-run flag is used then no changes will actually be made.

If the --json flag is used then the changes npm prune made (or would have made with --dry-run) are printed as a JSON object.

In normal operation with package-locks enabled, extraneous modules are pruned automatically when modules are installed and you'll only need this command with the --production flag.

If you've disabled package-locks then extraneous modules will not be removed and it's up to you to run npm prune from time-to-time to remove them.

Use npm-dedupe to reduce duplication

npm dedupe
npm ddp

Searches the local package tree and attempts to simplify the overall structure by moving dependencies further up the tree, where they can be more effectively shared by multiple dependent packages.

For example, consider this dependency graph:

a
+-- b <-- depends on [email protected]
|    `-- [email protected]
`-- d <-- depends on c@~1.0.9
     `-- [email protected]

In this case, npm-dedupe will transform the tree to:

 a
 +-- b
 +-- d
 `-- [email protected]

Because of the hierarchical nature of node's module lookup, b and d will both get their dependency met by the single c package at the root level of the tree.

The deduplication algorithm walks the tree, moving each dependency as far up in the tree as possible, even if duplicates are not found. This will result in both a flat and deduplicated tree.

You have a lot of unnecessary keyframes. Don't think of keyframes as individual frames, think of them as "steps" in your animation and the computer fills in the frames between the keyframes.

Here is a solution that cleans up a lot of code and makes the animation start from the center:

.gps_ring {
    border: 3px solid #999;
    -webkit-border-radius: 30px;
    height: 18px;
    width: 18px;
    position: absolute;
    left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You can see it in action here: http://jsfiddle.net/Fy8vD/

That's exactly what cursor: pointer; is supposed to do.

If you want the cursor to remain normal, you should be using cursor: default

From what I understand, Python lists are already quite similar to ArrayLists. But if you want to tweak those parameters I found this post on the Internet that may be interesting (basically, just create your own ScalableList extension):

http://mail.python.org/pipermail/python-list/2000-May/035082.html

The given answers stress the fact that emptyList() returns an immutable List but do not give alternatives. The Constructor ArrayList(int initialCapacity) special cases 0 so returning new ArrayList<>(0) instead of new ArrayList<>() might also be a viable solution:

/**
 * Shared empty array instance used for empty instances.
 */
private static final Object[] EMPTY_ELEMENTDATA = {};

[...]

/**
 * Constructs an empty list with the specified initial capacity.
 *
 * @param  initialCapacity  the initial capacity of the list
 * @throws IllegalArgumentException if the specified initial capacity
 *         is negative
 */
public ArrayList(int initialCapacity) {
    if (initialCapacity > 0) {
        this.elementData = new Object[initialCapacity];
    } else if (initialCapacity == 0) {
        this.elementData = EMPTY_ELEMENTDATA;
    } else {
        throw new IllegalArgumentException("Illegal Capacity: "+
                                           initialCapacity);
    }
}

It is strange, but why this topic is not have this answer:

$lastKey = array_keys($array)[count($array)-1];

I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.

@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
  INPUT[type="password"]{
  font-family:Verdana,sans-serif;
  height:28px;
  font-size:19px;
  width:223px;
  padding:5px;
  }
} /* END WEBKIT */

You can use

git add -u

To add the deleted files to the staging area, then commit them

git commit -m "Deleted files manually"

I had the same problem. This doesn't work:

npm uninstall -g angular/cli
npm cache clean

instead use:

npm uninstall -g @ angular/cli

You can get some limited memory information from the Runtime class. It really isn't exactly what you are looking for, but I thought I would provide it for the sake of completeness. Here is a small example. Edit: You can also get disk usage information from the java.io.File class. The disk space usage stuff requires Java 1.6 or higher.

public class Main {
  public static void main(String[] args) {
    /* Total number of processors or cores available to the JVM */
    System.out.println("Available processors (cores): " + 
        Runtime.getRuntime().availableProcessors());

    /* Total amount of free memory available to the JVM */
    System.out.println("Free memory (bytes): " + 
        Runtime.getRuntime().freeMemory());

    /* This will return Long.MAX_VALUE if there is no preset limit */
    long maxMemory = Runtime.getRuntime().maxMemory();
    /* Maximum amount of memory the JVM will attempt to use */
    System.out.println("Maximum memory (bytes): " + 
        (maxMemory == Long.MAX_VALUE ? "no limit" : maxMemory));

    /* Total memory currently available to the JVM */
    System.out.println("Total memory available to JVM (bytes): " + 
        Runtime.getRuntime().totalMemory());

    /* Get a list of all filesystem roots on this system */
    File[] roots = File.listRoots();

    /* For each filesystem root, print some info */
    for (File root : roots) {
      System.out.println("File system root: " + root.getAbsolutePath());
      System.out.println("Total space (bytes): " + root.getTotalSpace());
      System.out.println("Free space (bytes): " + root.getFreeSpace());
      System.out.println("Usable space (bytes): " + root.getUsableSpace());
    }
  }
}

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

df['First Season'].loc[(df['First Season'] > 1990)] = 1

strange that nobody has this answer, the only missing part of your code is the ['First Season'] right after df and just remove your curly brackets inside.

You can do something like this (taken from here):

import java.awt.FlowLayout;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.PlainDocument;

class JTextFieldLimit extends PlainDocument {
  private int limit;
  JTextFieldLimit(int limit) {
    super();
    this.limit = limit;
  }

  JTextFieldLimit(int limit, boolean upper) {
    super();
    this.limit = limit;
  }

  public void insertString(int offset, String str, AttributeSet attr) throws BadLocationException {
    if (str == null)
      return;

    if ((getLength() + str.length()) <= limit) {
      super.insertString(offset, str, attr);
    }
  }
}

public class Main extends JFrame {
  JTextField textfield1;

  JLabel label1;

  public void init() {
    setLayout(new FlowLayout());
    label1 = new JLabel("max 10 chars");
    textfield1 = new JTextField(15);
    add(label1);
    add(textfield1);
    textfield1.setDocument(new JTextFieldLimit(10));

    setSize(300,300);
    setVisible(true);
  }
}

Edit: Take a look at this previous SO post. You could intercept key press events and add/ignore them according to the current amount of characters in the textfield.

Use PHP's native json_encode, like this:

<?php
$arr = array(
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    )
);

echo json_encode($arr);
?>

Update: To answer your question in the comment. You do it like this:

$named_array = array(
    "nome_array" => array(
        array(
            "foo" => "bar"
        ),
        array(
            "foo" => "baz"
        )
    )
);
echo json_encode($named_array);

head takes the first lines from a file, and the -n parameter can be used to specify how many lines should be extracted:

line=$(head -n 1 filename)

Simple Copy this text and put on the before </body>

function disableselect(e) {
  return false
}

function reEnable() {
  return true
}

document.onselectstart = new Function ("return false")

if (window.sidebar) {
  document.onmousedown = disableselect
  document.onclick = reEnable
}

I know it is an old question, but for the record here is a kind of a solution to the problem of multiline lambda problem in which the result of one call is consumed by another call.

I hope it is not super hacky, since it is based only on standard library functions and uses no dunder methods.

Below is a simple example in which we start with x = 3 and then in the first line we add 1 and then in the second line we add 2 and get 6 as the output.

from functools import reduce

reduce(lambda data, func: func(data), [
    lambda x: x + 1,
    lambda x: x + 2
], 3)

## Output: 6

pDialog = new ProgressDialog(this);

    // Set progressbar message
    pDialog.setMessage("Buffering...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(false);
    // Show progressbar
    pDialog.show();

    try {
        // Start the MediaController
        MediaController mediacontroller = new MediaController(this);
        mediacontroller.setAnchorView(mVideoView);      

        Uri videoUri = Uri.parse(videoUrl);
        mVideoView.setMediaController(mediacontroller);
        mVideoView.setVideoURI(videoUri);

    } catch (Exception e) {

        e.printStackTrace();
    }

    mVideoView.requestFocus();
    mVideoView.setOnPreparedListener(new OnPreparedListener() {
        // Close the progress bar and play the video
        public void onPrepared(MediaPlayer mp) {
            pDialog.dismiss();
            mVideoView.start();
        }
    });
    mVideoView.setOnCompletionListener(new OnCompletionListener() {

        public void onCompletion(MediaPlayer mp) {
            if (pDialog.isShowing()) {
                pDialog.dismiss();
            }
            finish();               
        }
    });

Well there are two methods to access this data easier, but the interface doesn't offer the possibility to get the whole URL with one call. You have to build it manually:

public static String makeUrl(HttpServletRequest request)
{
    return request.getRequestURL().toString() + "?" + request.getQueryString();
}

I don't know about a way to do this with any Spring MVC facilities.

If you want to access the current Request without passing it everywhere you will have to add a listener in the web.xml:

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

And then use this to get the request bound to the current Thread:

((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest()

Have a same problem. My solution is after you handle with parsing arguments using argparse or other way, remove arguments from sys.argv

sys.argv = sys.argv[:1]  

If you need you can filter unittest arguments from main.parseArgs()

Update May 2020, installed Anaconda 3 Individual Edition from https://www.anaconda.com/products/individual, chose 32-bit installer for Python 3.7, and installed with Default options.

Here is the directory where Anaconda was installed (C:\ProgramData\Anaconda3). Note ProgramData is a hidden folder not visible via Windows File Explorer.

And launching Anaconda command prompt from Start Menu>>Anaconda3 gives below command shell

"where anaconda" command gives below output C:\ProgramData\Anaconda3\Scripts\anaconda.exe and versions for anaconda, conda, python

Updated original question which was asked 3 years ago, and is relevant today as well in May 2020 as I had similar question/doubt when installing Anaconda recently.

Here is the Angular version of LightBox. Just Awesome :)

Note : I have put this answer hence No Js library has been mentioned under the Tags.

angular-bootstrap-lightbox

<ul ng-controller="GalleryCtrl">
  <li ng-repeat="image in images">
    <a ng-click="openLightboxModal($index)">
      <img ng-src="{{image.thumbUrl}}" class="img-thumbnail">
    </a>
  </li>
</ul>

For completeness, using cut

cut -d : -f 2 <<< $var

And using only bash:

IFS=: read a b <<< $var ; echo $b

To differentiate the routes, try adding a constraint that id must be numeric:

RouteTable.Routes.MapHttpRoute(
         name: "DefaultApi",
         routeTemplate: "api/{controller}/{id}",
         constraints: new { id = @"\d+" }, // Only matches if "id" is one or more digits.
         defaults: new { id = System.Web.Http.RouteParameter.Optional }
         );  

You can skip fund using:

npm install --no-fund YOUR PACKAGE NAME

For example :

npm install --no-fund core-js

A quick algorithm that simulates the way that it work is the following:

public int toByte(int number) {
    int tmp = number & 0xff
    return (tmp & 0x80) == 0 ? tmp : tmp - 256;
}

How this work ? Look to daixtr answer. A implementation of exact algorithm discribed in his answer is the following:

public static int toByte(int number) {
    int tmp = number & 0xff;
    if ((tmp & 0x80) == 0x80) {
        int bit = 1;
        int mask = 0;
        for(;;) {
            mask |= bit;
            if ((tmp & bit) == 0) {
                bit <<=1;
                continue;
            }
            int left = tmp & (~mask);
            int right = tmp & mask;
            left = ~left;
            left &= (~mask);
            tmp = left | right;
            tmp = -(tmp & 0xff);
            break;
        }
    }
    return tmp;
}

If any of the above answers worked out, You can create new artifact directly from the admin side of (NEXUS Screen shot attached below).

1. Login to nexus UI http://YOUR_URL:8081/nexus( username: admin default password: admin123 )
2. Click repositories on the left side then click the repo, For eg: click release.
3. Choose artifact Upload (last tab).
4. Choose GAV definition as GAV Param- Then enter your groupid , artifact id and version .
5. Choose Jar file.
6. Click upload artifact. Thats it !

Now you will be able to add the corrsponding in your project.(screenshot below)

In my own case, i was using serialize() on the form, Hence the files were not being sent to php. If you are using jquery, use FormData(). For example

<form id='form'>
<input type='file' name='file' />
<input type='submit' />
</form>

Using jquery,

$('#form').submit(function (e) {
e.preventDefault();
var formData = new FormData(this); // grab all form contents including files
//you can then use formData and pass to ajax

});

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

For me the bold work when I change the font style from font-family: 'Open Sans', sans-serif; to Arial

You can use this library from JSON.org to translate your string into a JSON object.

var var1_obj = JSON.parse(var1);

Or you can use the jquery-json library as well.

var var1_obj = $.toJSON(var1);

From a Stack Overflow reference

It did not work with value="" if the browser already saves the value so you should add.

For an input tag there's the attribute autocomplete you can set:

<input type="text" autocomplete="off" />

You can use autocomplete for a form too.

here's a native javascript inline code to change image onmouseover & onmouseout:

<a href="#" id="name">
    <img title="Hello" src="/ico/view.png" onmouseover="this.src='/ico/view.hover.png'" onmouseout="this.src='/ico/view.png'" />
</a>

You can create one using like the following:

var dictionary = { Name:"Some Programmer", Age:24, Job:"Writing Programs"  };

// Iterate over using keys
for (var key in dictionary) {
  console.log("Key: " + key + " , " + "Value: "+ dictionary[key]);
}

// Access a key using object notation:
console.log("Her name is: " + dictionary.Name)

You can use this function

            String.prototype.format = function (args) {
            var str = this;
            return str.replace(String.prototype.format.regex, function(item) {
                var intVal = parseInt(item.substring(1, item.length - 1));
                var replace;
                if (intVal >= 0) {
                    replace = args[intVal];
                } else if (intVal === -1) {
                    replace = "{";
                } else if (intVal === -2) {
                    replace = "}";
                } else {
                    replace = "";
                }
                return replace;
            });
        };
        String.prototype.format.regex = new RegExp("{-?[0-9]+}", "g");

        // Sample usage.
        var str = "She {1} {0}{2} by the {0}{3}. {-1}^_^{-2}";
        str = str.format(["sea", "sells", "shells", "shore"]);
        alert(str);

I had the same issue when i reference the Class library into my MVC web application,

the issue was the nuget package version number mismatch between two projects.

ex: my class library had log4net of 1.2.3 but my webapp had 1.2.6

fix: just make sure both the project have the same version number referenced.

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

I did not know about Environment.Newline, but I guess this is a very good solution.

My try would have been:

        string str = "Test Me\r\nTest Me\nTest Me";
        var splitted = str.Split('\n').Select(s => s.Trim()).ToArray();

The additional .Trim removes any \r or \n that might be still present (e. g. when on windows but splitting a string with os x newline characters). Probably not the fastest method though.

EDIT:

As the comments correctly pointed out, this also removes any whitespace at the start of the line or before the new line feed. If you need to preserve that whitespace, use one of the other options.

PHP

Here is the PHP's version (input values are: $latitude and $longitude):

$latitude_pattern  = '/\A[+-]?(?:90(?:\.0{1,18})?|\d(?(?<=9)|\d?)\.\d{1,18})\z/x';
$longitude_pattern = '/\A[+-]?(?:180(?:\.0{1,18})?|(?:1[0-7]\d|\d{1,2})\.\d{1,18})\z/x';
if (preg_match($latitude_pattern, $latitude) && preg_match($longitude_pattern, $longitude)) {
  // Valid coordinates.
}

easy...

In your keyPress event handler, write

void ValidateKeyPressHandler(object sender, KeyPressEventArgs e)
{
    var tb = sender as TextBox;
    var startPos = tb.SelectionStart;
    var selLen= tb.SelectionLength;

    var afterEditValue = tb.Text.Remove(startPos, selLen)
                .Insert(startPos, e.KeyChar.ToString()); 
    //  ... more here
}

Solution for my particular scenario (It had been working a couple days before getting borked):

Port 80 was not the problem, but something I had done while messing around with Services and Startup.

1. Type msconfig on Windows' Start menu
2. Click System Configuration

Screenshot for System Configuration

3. In the Services tab, search for Apache24 (Click "Hide all Microsoft services" in the checkbox at the bottom of the window to make it easier to find)
4. If its checkbox isn't checked, check it

If it was already checked, then this guide isn't going to help. However if it is:

5. Click OK, your PC will have to restart
6. Try once again! In my case Apache was already running once I opened Xampp

Somehow your requirement sounds a bit contradictory ..

group by name (which is basically a distinct on name plus readiness to aggregate) and then a distinct on IP

What do you think should happen if two people (names) worked from the same IP within the time period specified?

Did you try this?

SELECT name, COUNT(name), time, price, ip, SUM(price) 
  FROM tablename 
 WHERE time >= $yesterday AND time <$today 
GROUP BY name,ip

The official way to find out if you have 4.5 installed (and not 4.0) is in the registry keys :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

Relesae DWORD needs to be bigger than 378675 Here is the Microsoft doc for it

all the other answers of checking the minor version after 4.0.30319.xxxxx seem correct though (msbuild.exe -version , or properties of clr.dll), i just needed something documented (not a blog)

Three simple choices.

Obvious

x, _ = func()

x, junk = func()

Hideous

x = func()[0]

And there are ways to do this with a decorator.

def val0( aFunc ):
    def pick0( *args, **kw ):
        return aFunc(*args,**kw)[0]
    return pick0

func0= val0(func)

Add tomcat in Eclipse

In Eclipse, as tomcat server, double click "Tomcat v7.0 Server at Localhost", Change the properties as shown in time out settings 45 to whatever sec you like

map.setZoom(map.getZoom());

For some reasons, resize trigger did not work for me, and this one worked.

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

Content Type for MOV videos are video/quicktime in my case. Adding type="video/mp4" to MOV video file solved issue in my case.

<video width="400" controls Autoplay=autoplay>
  <source src="D:/mov1.mov" type="video/mp4">
</video>

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

Not sure what your target is, but do you want the text to come on the second line?

Here is your jsFiddle: http://jsfiddle.net/8kvWX/4/ just removed the following:

You can add this line on top of your script:

#!/bin/bash
# redirect stdout/stderr to a file
exec &> logfile.txt

OR else to redirect only stdout use:

exec > logfile.txt

To figure out what is the difference between before_action and before_filter, we should understand the difference between action and filter.

An action is a method of a controller to which you can route to. For example, your user creation page might be routed to UsersController#new - new is the action in this route.

Filters run in respect to controller actions - before, after or around them. These methods can halt the action processing by redirecting or set up common data to every action in the controller.

Rails 4 –> _action

Rails 3 –> _filter

@Adam Davis, the code you entered is actually a jQuery call. If you already have the library loaded, that works just fine, otherwise you will need to append the CSS

<style type="text/css">
    #nav-ask{ display:none; }
</style>

or if you already have a "hideMe" CSS Class:

<script type="text/javascript">

    if(document.getElementById && document.createTextNode)
    {
        if(document.getElementById('nav-ask'))
        {
            document.getElementById('nav-ask').className='hideMe';
        }
    }

</script>

GZip Compression can be enabled directly through IIS.

First, open up IIS,

go to the website you are hoping to tweak and hit the Compression page. If Gzip is not installed, you will see something like the following:

“The dynamic content compression module is not installed.” We should fix this. So we go to the “Turn Windows features on or off” and select “Dynamic Content Compression” and click the OK button.

Now if we go back to IIS, we should see that the compression page has changed. At this point we need to make sure the dynamic compression checkbox is checked and we’re good to go. Compression is enabled and our dynamic content will be Gzipped.

Testing - Check if GZIP Compression is Enabled

To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:

Content-Encoding: gzip

In SQL Server, you can use this query:

USE Database_name

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME='Table_Name';

And do not forget to replace Database_name and Table_name with the exact names of your database and table names.

A MemoryStream can be helpful for this. You could put it in an extension method:

public static class ImageExtensions
{
    public static byte[] ToByteArray(this Image image, ImageFormat format)
    {
        using(MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, format);
            return ms.ToArray();
        }
    }
}

You could just use it like:

var image = new Bitmap(10, 10);
// Draw your image
byte[] arr = image.ToByteArray(ImageFormat.Bmp);

I partially disagree with prestomanifto's answer in regards to the ImageConverter. Do not use ImageConverter. There's nothing technically wrong with it, but simply the fact that it uses boxing/unboxing from object tells me it's code from the old dark places of the .NET framework and its not ideal to use with image processing (it's overkill for converting to a byte[] at least), especially when you consider the following.

I took a look at the ImageConverter code used by the .Net framework, and internally it uses code almost identical to the one I provided above. It creates a new MemoryStream, saves the Bitmap in whatever format it was in when you provided it, and returns the array. Skip the extra overhead of creating an ImageConverter class by using MemoryStream

I would suggest not to use JavaScript for this kind of simple interaction. CSS is capable of doing it (even in Internet Explorer 6) and it will be much more responsive than doing it with JavaScript.

You can use the ":hover" CSS pseudo-class but in order to make it work with Internet Explorer 6, you must use it on an "a" element.

.menuItem
{
    display: inline;
    background-color: #000;

    /* width and height should not work on inline elements */
    /* if this works, your browser is doing the rendering  */
    /* in quirks mode which will not be compatible with    */
    /* other browsers - but this will not work on touch mobile devices like android */

}
.menuItem a:hover 
{
    background-color:#F00;
}

I would say angular.copy(source); in your situation is unnecessary if later on you do not use is it without a destination angular.copy(source, [destination]);.

If a destination is provided, all of its elements (for arrays) or properties (for objects) are deleted and then all elements/properties from the source are copied to it.

This is my current way of doing it for bash (tested on Debian). Maybe there's a better way:

Don't do it with exec bash, for example like this:

#!/bin/bash
cd $1
exec bash

because while it appears to work, after you run it and your script finishes, yes you'll be in the correct directory, but you'll be in it in a subshell, which you can confirm by pressing Ctrl+D afterwards, and you'll see it exits the subshell, putting you back in your original directory.

This is usually not a state you want a script user to be left in after the script they run returns, because it's non-obvious that they're in a subshell and now they basically have two shells open when they thought they only had one. They might continue using this subshell and not realize it, and it could have unintended consequences.

If you really want the script to exit and leave open a subshell in the new directory, it's better if you change the PS1 variable so the script user has a visual indicator that they still have a subshell open.

Here's an example I came up with. It is two files, an outer.sh which you call directly, and an inner.sh which is sourced inside the outer.sh script. The outer script sets two variables, then sources the inner script, and afterwards it echoes the two variables (the second one has just been modified by the inner script). Afterwards it makes a temp copy of the current user's ~/.bashrc file, adds an override for the PS1 variable in it, as well as a cleanup routine, and finally it runs exec bash --rcfile pointing at the .bashrc.tmp file to initialize bash with a modified environment, including the modified prompt and the cleanup routine.

After outer.sh exits, you'll be left inside a subshell in the desired directory (in this case testdir/ which was entered into by the inner.sh script) with a visual indicator making it clear to you, and if you exit out of the subshell, the .bashrc.tmp file will be deleted by the cleanup routine, and you'll be back in the directory you started in.

Maybe there's a smarter way to do it, but that's the best way I could figure out in about 40 minutes of experimenting:

file 1: outer.sh

#!/bin/bash

var1="hello"
var2="world"

source inner.sh

echo $var1
echo $var2

cp ~/.bashrc .bashrc.tmp

echo 'export PS1="(subshell) $PS1"' >> .bashrc.tmp

cat <<EOS >> .bashrc.tmp
cleanup() {
    echo "cleaning up..."
    rm .bashrc.tmp
}

trap 'cleanup' 0
EOS

exec bash --rcfile .bashrc.tmp

file 2: inner.sh

cd testdir
var2="bird"

then run:

$ mkdir testdir
$ chmod 755 outer.sh

$ ./outer.sh

it should output:

hello
bird

and then drop you into your subshell using exec bash, but with a modified prompt which makes that obvious, something like:

(subshell) user@computername:~/testdir$

and if you Ctrl-D out of the subshell, it should clean up by deleting a temporary .bashrc.tmp file in the testdir/ directory

I wonder if there's a better way than having to copy the .bashrc file like that though to change the PS1 var properly in the subshell...

$(this).parent().parent().attr('id');

Is how you would get the id of the parent's parent.

EDIT:

$(this).closest('ul').attr('id');

Is a more foolproof solution for your case.

To handle spaces, @, and other unsafe characters in arbitrary locations in the url path, Use Uri.Builder in combination with a local instance of URL as I have described here:

private Uri.Builder builder;
public Uri getUriFromUrl(String thisUrl) {
    URL url = new URL(thisUrl);
    builder =  new Uri.Builder()
                            .scheme(url.getProtocol())
                            .authority(url.getAuthority())
                            .appendPath(url.getPath());
    return builder.build();
}

Shell scripts, no matter how they are executed, execute one command after the other. So your code will execute results.sh after the last command of st_new.sh has finished.

Now there is a special command which messes this up: &

cmd &

means: "Start a new background process and execute cmd in it. After starting the background process, immediately continue with the next command in the script."

That means & doesn't wait for cmd to do it's work. My guess is that st_new.sh contains such a command. If that is the case, then you need to modify the script:

cmd &
BACK_PID=$!

This puts the process ID (PID) of the new background process in the variable BACK_PID. You can then wait for it to end:

while kill -0 $BACK_PID ; do
    echo "Process is still active..."
    sleep 1
    # You can add a timeout here if you want
done

or, if you don't want any special handling/output simply

wait $BACK_PID

Note that some programs automatically start a background process when you run them, even if you omit the &. Check the documentation, they often have an option to write their PID to a file or you can run them in the foreground with an option and then use the shell's & command instead to get the PID.

This method is a bit different, it provided me with a bit more flexibility than the previous answer. By making it into an ordered factor, you can use it nicely in arrange and such. I used reorder.factor from the gdata package.

df <- data.frame(name=letters[1:4], value=c(rep(TRUE, 2), rep(FALSE, 2)))
target <- c("b", "c", "a", "d")

require(gdata)
df$name <- reorder.factor(df$name, new.order=target)

Next, use the fact that it is now ordered:

require(dplyr)
df %>%
  arrange(name)
    name value
1    b  TRUE
2    c FALSE
3    a  TRUE
4    d FALSE

If you want to go back to the original (alphabetic) ordering, just use as.character() to get it back to the original state.

It is privacy concern. It is recommended to disallow users to backup an app if it contains sensitive data. Having access to backup files (i.e. when android:allowBackup="true"), it is possible to modify/read the content of an app even on a non-rooted device.

Solution - use android:allowBackup="false" in the manifest file.

There is some basic pattern matching available through using LIKE, where % matches any number and combination of characters, _ matches any one character, and [abc] could match a, b, or c... There is more info on the MSDN site.

I had this issue with sites running on XAMPP with private hostnames. Not so private, it turns out! They were all domain.dev, which Google has now registered as a private gTLD, and is forcing HSTS at the domain level. Changed every virtual host to .devel (eugh), restarted Apache and all is now well.

First I am afraid your question contains a little mistake. There is not method writeline in class Console. Instead class Console provides method writer() that returns PrintWriter. This print writer has println().

Now what is the difference between

System.console().writer().println("hello from console");

and

System.out.println("hello system out");

If you run your application from command line I think there is no difference. But if console is unavailable System.console() returns null while System.out still exists. This may happen if you invoke your application and perform redirect of STDOUT to file.

Here is an example I have just implemented.

import java.io.Console;


public class TestConsole {
    public static void main(String[] args) {
        Console console = System.console();
        System.out.println("console=" + console);
        console.writer().println("hello from console");
    }
}

When I ran the application from command prompt I got the following:

$ java TestConsole
console=java.io.Console@93dcd
hello from console

but when I redirected the STDOUT to file...

$ java TestConsole >/tmp/test
Exception in thread "main" java.lang.NullPointerException
        at TestConsole.main(TestConsole.java:8)

Line 8 is console.writer().println().

Here is the content of /tmp/test

console=null

I hope my explanations help.

Refining the original solution (in C#):

public static class ExcelHelper
{
    private static Dictionary<UInt16, String> l_DictionaryOfColumns;

    public static ExcelHelper() {
        l_DictionaryOfColumns = new Dictionary<ushort, string>(256);
    }

    public static String GetExcelColumnName(UInt16 l_Column)
    {
        UInt16 l_ColumnCopy = l_Column;
        String l_Chars = "0ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        String l_rVal = "";
        UInt16 l_Char;


        if (l_DictionaryOfColumns.ContainsKey(l_Column) == true)
        {
            l_rVal = l_DictionaryOfColumns[l_Column];
        }
        else
        {
            while (l_ColumnCopy > 26)
            {
                l_Char = l_ColumnCopy % 26;
                if (l_Char == 0)
                    l_Char = 26;

                l_ColumnCopy = (l_ColumnCopy - l_Char) / 26;
                l_rVal = l_Chars[l_Char] + l_rVal;
            }
            if (l_ColumnCopy != 0)
                l_rVal = l_Chars[l_ColumnCopy] + l_rVal;

            l_DictionaryOfColumns.ContainsKey(l_Column) = l_rVal;
        }

        return l_rVal;
    }
}

If I understood correct,You need to set time zone first like:

date_default_timezone_set('UTC');

And than you can use date function:

// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');

To convert an integer to a float in Python you can use the following:

float_version = float(int_version)

The reason you are getting 0 is that Python 2 returns an integer if the mathematical operation (here a division) is between two integers. So while the division of 144 by 314 is 0.45~~~, Python converts this to integer and returns just the 0 by eliminating all numbers after the decimal point.

Alternatively you can convert one of the numbers in any operation to a float since an operation between a float and an integer would return a float. In your case you could write float(144)/314 or 144/float(314). Another, less generic code, is to say 144.0/314. Here 144.0 is a float so it’s the same thing.

This simple method worked for me perfectly in Windows 7:

    private void BringToFront() {
        java.awt.EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                if(jFrame != null) {
                    jFrame.toFront();
                    jFrame.repaint();
                }
            }
        });
    }

ActiveSheet.Range("A10000").End(xlup).offset(1,0).Select

The CardView worked for me in API 27 in Android Studio 3.0.1. The colorPrimary was referenced in the res/values/colors.xml file and is just an example. For the layout_width of 0dp it will stretch to the width of the parent. You'll have to configure the constraints and width/height to your needs.

<android.support.v7.widget.CardView
    android:id="@+id/cardView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:cardCornerRadius="4dp"
    app:cardBackgroundColor="@color/colorPrimary">

    <!-- put your content here -->

</android.support.v7.widget.CardView>

Ensure that you have turned ON the location services on the device. Else you won't get any location related info.

This works for me,

    map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    map.setMyLocationEnabled(true);
    GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
        @Override
        public void onMyLocationChange (Location location) {
           LatLng loc = new LatLng (location.getLatitude(), location.getLongitude());
           map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
        }
    };
    map.setOnMyLocationChangeListener(myLocationChangeListener);

}

Short Answer:

You likely want to use gpg instead of openssl so see "Additional Notes" at the end of this answer. But to answer the question using openssl:

To Encrypt:

openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data

To Decrypt:

openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

Long Answer:

Your best source of information for openssl enc would probably be: https://www.openssl.org/docs/man1.1.1/man1/enc.html

Command line: openssl enc takes the following form:

openssl enc -ciphername [-in filename] [-out filename] [-pass arg]
[-e] [-d] [-a/-base64] [-A] [-k password] [-kfile filename] 
[-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p] [-P] 
[-bufsize number] [-nopad] [-debug] [-none] [-engine id]

Explanation of most useful parameters with regards to your question:

-e
    Encrypt the input data: this is the default.

-d    
    Decrypt the input data.

-k <password>
    Only use this if you want to pass the password as an argument. 
    Usually you can leave this out and you will be prompted for a 
    password. The password is used to derive the actual key which 
    is used to encrypt your data. Using this parameter is typically
    not considered secure because your password appears in 
    plain-text on the command line and will likely be recorded in 
    bash history.

-kfile <filename>
    Read the password from the first line of <filename> instead of
    from the command line as above.

-a
    base64 process the data. This means that if encryption is taking 
    place the data is base64 encoded after encryption. If decryption 
    is set then the input data is base64 decoded before being 
    decrypted.
    You likely DON'T need to use this. This will likely increase the
    file size for non-text data. Only use this if you need to send 
    data in the form of text format via email etc.

-salt
    To use a salt (randomly generated) when encrypting. You always
    want to use a salt while encrypting. This parameter is actually
    redundant because a salt is used whether you use this or not 
    which is why it was not used in the "Short Answer" above!

-K key    
    The actual key to use: this must be represented as a string
    comprised only of hex digits. If only the key is specified, the
    IV must additionally be specified using the -iv option. When 
    both a key and a password are specified, the key given with the
    -K option will be used and the IV generated from the password 
    will be taken. It probably does not make much sense to specify 
    both key and password.

-iv IV
    The actual IV to use: this must be represented as a string 
    comprised only of hex digits. When only the key is specified 
    using the -K option, the IV must explicitly be defined. When a
    password is being specified using one of the other options, the 
    IV is generated from this password.

-md digest
    Use the specified digest to create the key from the passphrase.
    The default algorithm as of this writing is sha-256. But this 
    has changed over time. It was md5 in the past. So you might want
    to specify this parameter every time to alleviate problems when
    moving your encrypted data from one system to another or when
    updating openssl to a newer version.

Additional Notes:

Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups?

To use GPG to do the same you would use the following commands:

To Encrypt:

gpg --output encrypted.data --symmetric --cipher-algo AES256 un_encrypted.data

To Decrypt:

gpg --output un_encrypted.data --decrypt encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

Unfortunately, for some reasons probably linked with HTTPS and certificates, the native .NET HttpListener requires admin privileges, and even for HTTP only protocol...

The good point

It is interesting to note that HTTP protocol is on top of TCP protocol, but launching a C# TCP listener doesn't require any admin privileges to run. In other words, it is conceptually possible to implement an HTTP server which do not requires admin privileges.

Alternative

Below, an example of project which doesn't require admin privileges: https://github.com/EmilianoElMariachi/ElMariachi.Http.Server

You need to ensure that auto-commit on the Connection is turned off, or setFetchSize will have no effect.

dbConnection.setAutoCommit(false);

Edit: Remembered that when I used this fix it was Postgres-specific, but hopefully it will still work for SQL Server.

It uses indentation

I tried with the following and it's worked:

release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

I Understood your problem add this dependency in your pom.xml your problem will be solved,

https://mvnrepository.com/artifact/mysql/mysql-connector-java/5.1.38

To iterate through all the inputs in a form you can do this:

$("form#formID :input").each(function(){
 var input = $(this); // This is the jquery object of the input, do what you will
});

This uses the jquery :input selector to get ALL types of inputs, if you just want text you can do :

$("form#formID input[type=text]")//...

etc.

Using dependency injection in your constructor makes managing the lifetime of your HttpClient easier - taking the lifetime managemant outside of the code that needs it and making it easily changable at a later date.

My current preference is to create a seperate http client class that inherits from HttpClient once per target endpoint domain and then make it a singleton using dependency injection. public class ExampleHttpClient : HttpClient { ... }

Then I take a constructor dependency on the custom http client in the service classes where I need access to that API. This solves the lifetime problem and has advantages when it comes to connection pooling.

You can see a worked example in related answer at https://stackoverflow.com/a/50238944/3140853

This code should work. If it doesn't, check the sources in your debugger tool (Press F12 or Ctrl+Shift+I in Google Chrome). If you can't find the fn1() function there then, press Ctrl+F5, to fully reload the site (Ctrl+R or F5 isn't enough). After reloading the page, it should work.

You're not saying how exactly putdata() is not behaving. I'm assuming you're doing

>>> pic.putdata(a)
Traceback (most recent call last):
  File "...blablabla.../PIL/Image.py", line 1185, in putdata
    self.im.putdata(data, scale, offset)
SystemError: new style getargs format but argument is not a tuple

This is because putdata expects a sequence of tuples and you're giving it a numpy array. This

>>> data = list(tuple(pixel) for pixel in pix)
>>> pic.putdata(data)

will work but it is very slow.

As of PIL 1.1.6, the "proper" way to convert between images and numpy arrays is simply

>>> pix = numpy.array(pic)

although the resulting array is in a different format than yours (3-d array or rows/columns/rgb in this case).

Then, after you make your changes to the array, you should be able to do either pic.putdata(pix) or create a new image with Image.fromarray(pix).

In eclipse help documentation, we can all icons information as follows. Common path for all eclipse versions except eclipse version:

https://help.eclipse.org/2019-09/index.jsp?nav=%2F1

A different approach to your problem...

There are 3 ways to bind the hashchange event to a method:

<script>
    window.onhashchange = doThisWhenTheHashChanges;
</script>

Or

<script>
    window.addEventListener("hashchange", doThisWhenTheHashChanges, false);
</script>

Or

<body onhashchange="doThisWhenTheHashChanges();">

These all work with IE 9, FF 5, Safari 5, and Chrome 12 on Win 7.

Especially if you use a copy-on-write filesystem like BTRFS or ZFS, rsync is much better.

I use BTRFS, and I have this in my ~/.bashrc:

alias cp="rsync -ah --inplace --no-whole-file --info=progress2"

The important flag here for CoW FSs like BTRFS is --inplace because it only copies the changed part of the files, doesn't create new for small changes between files inodes, etc. See this.

CAST uses ANSI standard. In case of portability, this will work on other platforms. CONVERT is specific to sql server. But is very strong function. You can specify different styles for dates

I met this issue too. When I add dependencies in the pom.xml, I checked in the local folder /Users/xyz/.m2/ and the jars are already downloaded there, but cann't added the the buildpath of the eclipse.

My eclipse Version: Mars.2 Release (4.5.2)

right click project > Maven > Enable Workspace Resolution

And this solved my issue.

Interesting. I have a few questions which may point out the problem.

1/ Are you untarring on the same platform as you're tarring on? They may be different versions of tar (e.g., GNU and old-unix)? If they're different, can you untar on the same box you tarred on?

2/ What happens when you simply gunzip myarchive.tar.gz? Does that work? Maybe your file is being corrupted/truncated. I'm assuming you would notice if the compression generated errors, yes?

Based on the GNU tar source, it will only print that message if find_next_block() returns 0 prematurely which is usually caused by truncated archive.

In case that you want to add a class to a form's field in a template (not in view.py or form.py) for example in cases that you want to modify 3rd party apps without overriding their views, then a template filter as described in Charlesthk answer is very convenient. But in this answer the template filter overrides any existing classes that the field might has.

I tried to add this as an edit but it was suggested to be written as a new answer.

So, here is a template tag that respects the existing classes of the field:

from django import template

register = template.Library()


@register.filter(name='addclass')
def addclass(field, given_class):
    existing_classes = field.field.widget.attrs.get('class', None)
    if existing_classes:
        if existing_classes.find(given_class) == -1:
            # if the given class doesn't exist in the existing classes
            classes = existing_classes + ' ' + given_class
        else:
            classes = existing_classes
    else:
        classes = given_class
    return field.as_widget(attrs={"class": classes})

Hey guys I know it's an old thread but I am just posting this for reference to anybody else who visited this like me. If i understood the question correctly, I think the locate $filename command. It displays the absolute path of the file supplied, but only if it exists.

I (and the rest of our team in my company) prefer to raise exceptions instead of returning error codes. Error codes have to be checked everywhere, passed around, and tend to make the code unreadable when the amount of code becomes bigger.

The error class would then define the message.

PS: and actually also care for internationalization !
PPS: you could also redefine the raise-method and add logging, filtering etc. if required (at leastin environments, where the Exception classes and friends are extendable/changeable)

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

One way is to use sets:

>>> set([1,2,6,8]) - set([2,3,5,8])
set([1, 6])

Note, however, that sets do not preserve the order of elements, and cause any duplicated elements to be removed. The elements also need to be hashable. If these restrictions are tolerable, this may often be the simplest and highest performance option.

I had the same error. The cause was that I had created a table with wrong schema(it ought to be [dbo]). I did the following steps:

1. I dropped all tables which does not have a prefix "dbo."

2. I created and run this query:

CREATE TABLE dbo.Cars(IDCar int PRIMARY KEY NOT NULL,Name varchar(25) NOT NULL,    
CarDescription text NULL)

For anyone stumbling across the same issue:

I fixed the problem by cloning the repo again at another location. I then copied my whole src dir (without .git dir obviously) from the corrupted repo into the freshly cloned repo. Thus I had all the recent changes and a clean and working repository.

By loading the .js file first and then calling the function via onclick, there's less coding and it's fairly obvious what's going on. We'll call the JS file zipcodehelp.js.

HTML:

<!DOCTYPE html>
<html>
<head>
    <title>Button to call JS function.</title>
</head>
<body>
    <h1>Use Button to execute function in '.js' file.</h1>
    <script type="text/javascript" src="zipcodehelp.js"></script>
    <button onclick="ZipcodeHelp();">Get Zip Help!</button>
</body>
</html>

And the contents of zipcodehelp.js is :

function ZipcodeHelp() {
  alert("If Zipcode is missing in list at left, do: \n\n\
    1. Enter any zipcode and click Create Client. \n\
    2. Goto Zipcodes and create new zip code. \n\
    3. Edit this new client from the client list.\n\
    4. Select the new zipcode." );
}

Hope that helps! Cheers!

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

i want to make visaCard-note div to be visible only if selected cardType is visa

and here is the html

<select name="cardType">
    <option value="1">visa</option>
    <option value="2">mastercard</option>
</select>

here is the js

var visa="1";//visa is selected by default 
$("select[name=cardType]").change(function () {
    document.getElementById('visaCard-note').style.visibility = this.value==visa ? 'visible' : 'hidden';
})

I had same problem. I wanted to edit ENUM values in table structure. Problem was because of rows that was saved before and new ENUM values doesn't contain saved values.

Solution was updating old saved rows in MySql table.

select * 
from blah 
where DatetimeField between '22/02/2009 09:00:00.000' and '23/05/2009 10:30:00.000'

Depending on the country setting for the login, the month/day may need to be swapped around.

It would be easier to use XML in SQL Server to insert multiple rows otherwise it becomes very tedious.

Suppose your dataframe is df and you want to change gender from 2 to 1 in participant id 5 then you should determine the row by writing "==" as you can see

 df["rowName", "columnName"] <- value
 df[df$serial.id==5, "gender"] <- 1

This Method to get Google Username:

Bulk inserting a unknown width file with \n row terminators into a temp table that is created outside of the EXEC statement.

DECLARE     @SQL VARCHAR(8000)

IF OBJECT_ID('TempDB..#BulkInsert') IS NOT NULL

CREATE TABLE #BulkInsert
(
    Line    VARCHAR(MAX)
)

SET @SQL = 'BULK INSERT #BulkInser FROM ''##FILEPATH##'' WITH (ROWTERMINATOR = ''\n'')'
EXEC (@SQL)

SELECT * FROM #BulkInsert

Further support, written for MSSQL2000 http://technet.microsoft.com/en-us/library/aa175921(v=sql.80).aspx

Example at the bottom of the link

DECLARE @cmd VARCHAR(1000), @ExecError INT
CREATE TABLE #ErrFile (ExecError INT)

'''pubs.dbo.authors''' + 
'INSERT #ErrFile VALUES(@@ERROR)'
EXEC(@cmd)
SET @ExecError = (SELECT * FROM #ErrFile)
SELECT @ExecError AS '@@ERROR'

you have to reason in terms of hased password:

store the password as md5('bob123'); when bob is register to your app

$query = "INSERT INTO users (username,password) VALUES('bob','".md5('bob123')."');

then, when bob is logging-in:

$query = "SELECT * FROM users WHERE username = 'bob' AND password = '".md5('bob123')."';

obvioulsy use variables for username and password, these queries are generated by php and then you can execute them on mysql

Actually I would advocate .profile if you need it to work from scripts, and in particular, scripts run by /bin/sh instead of Bash. If this is just for your own private interactive use, .bashrc is fine, though.

I think, jogojapan gave an very good and exhaustive answer. You definitively should take a look at it before reading my post. However, I'd like to add the following:

1. You can define a comparison function for an unordered_map separately, instead of using the equality comparison operator (operator==). This might be helpful, for example, if you want to use the latter for comparing all members of two Node objects to each other, but only some specific members as key of an unordered_map.
2. You can also use lambda expressions instead of defining the hash and comparison functions.

All in all, for your Node class, the code could be written as follows:

using h = std::hash<int>;
auto hash = [](const Node& n){return ((17 * 31 + h()(n.a)) * 31 + h()(n.b)) * 31 + h()(n.c);};
auto equal = [](const Node& l, const Node& r){return l.a == r.a && l.b == r.b && l.c == r.c;};
std::unordered_map<Node, int, decltype(hash), decltype(equal)> m(8, hash, equal);

Notes:

• I just reused the hashing method at the end of jogojapan's answer, but you can find the idea for a more general solution here (if you don't want to use Boost).
• My code is maybe a bit too minified. For a slightly more readable version, please see this code on Ideone.

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

A use case for it when you want to use a table with *ngIf and *ngFor - As putting a div in td/th will make the table element misbehave -. I faced this problem and that was the answer.

Swift 4.2, Xcode 10+

For those wondering how to do this with VCs not set up via the storyboard (those coming to this question from searching "programmatically" + "unwind segue").

Given that you cannot set up an unwind segue programatically, the simplest solely programmatic solution is to call:

navigationController?.popToRootViewController(animated: true)

which will pop all view controllers on the stack back to your root view controller.

To pop just the topmost view controller from the navigation stack, use:

navigationController?.popViewController(animated: true)

This isn't really a fixing solution but it may help others. Unlike Nick had said for me it was due to code in my program. I have the mega ADK model. The issue was tied to a switch statement for processing and parsing the returned byte[] from the usb connection to the Android. Its very strange because it would compile perfectly every time but would fail as the OP had stated. I commented it out and it worked fine.

(Note: root, base, apex domains are all the same thing. Using interchangeably for google-foo.)

Traditionally, to point your apex domain you'd use an A record pointing to your server's IP. This solution doesn't scale and isn't viable for a cloud platform like Heroku, where multiple and frequently changing backends are responsible for responding to requests.

For subdomains (like www.example.com) you can use CNAME records pointing to your-app-name.herokuapp.com. From there on, Heroku manages the dynamic A records behind your-app-name.herokuapp.com so that they're always up-to-date. Unfortunately, the DNS specification does not allow CNAME records on the zone apex (the base domain). (For example, MX records would break as the CNAME would be followed to its target first.)

Back to root domains, the simple and generic solution is to not use them at all. As a fallback measure, some DNS providers offer to setup an HTTP redirect for you. In that case, set it up so that example.com is an HTTP redirect to www.example.com.

Some DNS providers have come forward with custom solutions that allow CNAME-like behavior on the zone apex. To my knowledge, we have DNSimple's ALIAS record and DNS Made Easy's ANAME record; both behave similarly.

Using those, you could setup your records as (using zonefile notation, even tho you'll probably do this on their web user interface):

@   IN ALIAS your-app-name.herokuapp.com.
www IN CNAME your-app-name.herokuapp.com.

Remember @ here is a shorthand for the root domain (example.com). Also mind you that the trailing dots are important, both in zonefiles, and some web user interfaces.

See also:

• Doing DNS right with Heroku
• Avoiding Naked Domains and DNS A-records

Remarks:

• Amazon's Route 53 also has an ALIAS record type, but it's somewhat limited, in that it only works to point within AWS. At the moment I would not recommend using this for a Heroku setup.

• Some people confuse DNS providers with domain name registrars, as there's a bit of overlap with companies offering both. Mind you that to switch your DNS over to one of the aforementioned providers, you only need to update your nameserver records with your current domain registrar. You do not need to transfer your domain registration.

With JQM 1.4.2 this one works for me (Change theme to the used one):

.ui-page-theme-b, .ui-page-theme-b .ui-panel-wrapper {
    background: transparent url(../img/xxx) !important;
    background-repeat:repeat !important;
}

As of the current JRE implementation, Function.identity() will always return the same instance while each occurrence of identifier -> identifier will not only create its own instance but even have a distinct implementation class. For more details, see here.

The reason is that the compiler generates a synthetic method holding the trivial body of that lambda expression (in the case of x->x, equivalent to return identifier;) and tell the runtime to create an implementation of the functional interface calling this method. So the runtime sees only different target methods and the current implementation does not analyze the methods to find out whether certain methods are equivalent.

So using Function.identity() instead of x -> x might save some memory but that shouldn’t drive your decision if you really think that x -> x is more readable than Function.identity().

You may also consider that when compiling with debug information enabled, the synthetic method will have a line debug attribute pointing to the source code line(s) holding the lambda expression, therefore you have a chance of finding the source of a particular Function instance while debugging. In contrast, when encountering the instance returned by Function.identity() during debugging an operation, you won’t know who has called that method and passed the instance to the operation.

The Groovy way to do this is

def list = []
list << new MyType(...)

which creates a list and uses the overloaded leftShift operator to append an item

See the Groovy docs on Lists for lots of examples.

Replace the string delimiter with a single character, then split on that character.

string input = "abc][rfd][5][,][.";
string[] parts1 = input.Replace("][","-").Split('-');

1. try telnet 3306. If it doesn't open connection, either there is a firewall setting or the server isn't listening (or doesn't work).

2. run netstat -an on server to see if server is up.

3. It's possible that you don't allow remote connections.

Assuming that I is your input image and F is its Fourier Transform (i.e. F = fft2(I))

You can use this code:

F = fftshift(F); % Center FFT

F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1

imshow(F,[]); % Display the result

For me it was because of ipfs extension in brave browser

There is a much simpler way to do it using seaborn:

import seaborn as sns
from scipy.stats import norm

data = norm.rvs(5,0.4,size=1000) # you can use a pandas series or a list if you want

sns.distplot(data)
plt.show()

output:

Use of finishAffinity() may be an good option if you want to close all Activity of the app. As per the Android Docs-

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

Including use strict in the beginning of your all sensitive JavaScript files from this point is a small way to be a better JavaScript programmer and avoid random variables becoming global and things change silently.

Syntax: error_log file | stderr | syslog:server=address[,parameter=value] | memory:size [debug | info | notice | warn | error | crit | alert | emerg];

I had a similar problem and found the following command to work:

sudo systemctl stop tomcat

After running this command you can type the following to verify that it is "disabled":

systemctl list-units

It is .shape:

ndarray.shape
Tuple of array dimensions.

Thus:

I got this problem when using jQuery's .clone method. I replaced these by using making jQuery objects from the html string: $($(selector).html()).

In a new PHP7 there is a finally a support for a cryptographically secure pseudo-random integers.

int random_int ( int $min , int $max )

random_int — Generates cryptographically secure pseudo-random integers

which basically makes previous answers obsolete.

Python iterable can be summed like so - [sum(range(10)[1:])] . This sums all elements from the list except the first element.

>>> atuple = (1,2,3,4,5)
>>> sum(atuple)
15
>>> alist = [1,2,3,4,5]
>>> sum(alist)
15

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

You can add New Symbol Image Set in .xcassets, then you can add SVG file in it

and use it same like image.

Note: This doesn't work on all SVG. You can have a look at the apple documentation

For capital letters:

i=67
letters=({A..Z})
echo "${letters[$i-65]}"

Output:

C

div#a {
  background-image: none !important;
}

Although the "!important" might not be necessary, because "div#a" has a higher specificity than just "div".

/(.*)<FooBar>/s

the s causes Dot (.) to match carriage returns

The general rule seems to be that browsers encode form responses according to the content-type of the page the form was served from. This is a guess that if the server sends us "text/xml; charset=iso-8859-1", then they expect responses back in the same format.

If you're just entering a URL in the URL bar, then the browser doesn't have a base page to work on and therefore just has to guess. So in this case it seems to be doing utf-8 all the time (since both your inputs produced three-octet form values).

The sad truth is that AFAIK there's no standard for what character set the values in a query string, or indeed any characters in the URL, should be interpreted as. At least in the case of values in the query string, there's no reason to suppose that they necessarily do correspond to characters.

It's a known problem that you have to tell your server framework which character set you expect the query string to be encoded as--- for instance, in Tomcat, you have to call request.setEncoding() (or some similar method) before you call any of the request.getParameter() methods. The dearth of documentation on this subject probably reflects the lack of awareness of the problem amongst many developers. (I regularly ask Java interviewees what the difference between a Reader and an InputStream is, and regularly get blank looks)

Update - a better version

This tool (https://github.com/mklepaczewski/git-clean-before-merge) will:

• delete untracked files that are identical to their git pull equivalents,
• revert changes to modified files who's modified version is identical to their git pull equivalents,
• report modified/untracked files that differ from their git pull version,
• the tool has the --pretend option that will not modify any files.

Old version

How this answer differ from other answers?

The method presented here removes only files that would be overwritten by merge. If you have other untracked (possibly ignored) files in the directory this method won't remove them.

The solution

This snippet will extract all untracked files that would be overwritten by git pull and delete them.

git pull 2>&1|grep -E '^\s'|cut -f2-|xargs -I {} rm -rf "{}"

and then just do:

git pull

This is not git porcelain command so always double check what it would do with:

git pull 2>&1|grep -E '^\s'|cut -f2-|xargs -I {} echo "{}"

Explanation - because one liners are scary:

Here's a breakdown of what it does:

1. git pull 2>&1 - capture git pull output and redirect it all to stdout so we can easily capture it with grep.
2. grep -E '^\s - the intent is to capture the list of the untracked files that would be overwritten by git pull. The filenames have a bunch of whitespace characters in front of them so we utilize it to get them.
3. cut -f2- - remove whitespace from the beginning of each line captured in 2.
4. xargs -I {} rm -rf "{}" - us xargs to iterate over all files, save their name in "{}" and call rm for each of them. We use -rf to force delete and remove untracked directories.

It would be great to replace steps 1-3 with porcelain command, but I'm not aware of any equivalent.

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.

For instance, very often training a neural network is supervised learning: you're telling the network to which class corresponds the feature vector you're feeding.

Clustering is unsupervised learning: you let the algorithm decide how to group samples into classes that share common properties.

Another example of unsupervised learning is Kohonen's self organizing maps.

Funtional efficiency is totally different. If you would like to select only "return value" except duplicate one, use distinct is better than group by. Because "group by" include ( sorting + removing ) , "distinct" include ( removing )

You can use the $$ variable.

LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.

text-overflow:ellipsis; only works when the following are true:

• The element's width must be constrained in px (pixels). Width in % (percentage) won't work.
• The element must have overflow:hidden and white-space:nowrap set.

The reason you're having problems here is because the width of your a element isn't constrained. You do have a width setting, but because the element is set to display:inline (i.e. the default) it is ignoring it, and nothing else is constraining its width either.

You can fix this by doing one of the following:

• Set the element to display:inline-block or display:block (probably the former, but depends on your layout needs).
• Set one of its container elements to display:block and give that element a fixed width or max-width.
• Set the element to float:left or float:right (probably the former, but again, either should have the same effect as far as the ellipsis is concerned).

I'd suggest display:inline-block, since this will have the minimum collateral impact on your layout; it works very much like the display:inline that it's using currently as far as the layout is concerned, but feel free to experiment with the other points as well; I've tried to give as much info as possible to help you understand how these things interact together; a large part of understanding CSS is about understanding how various styles work together.

Here's a snippet with your code, with a display:inline-block added, to show how close you were.

.app a {_x000D_
  height: 18px;_x000D_
  width: 140px;_x000D_
  padding: 0;_x000D_
  overflow: hidden;_x000D_
  position: relative;_x000D_
  display: inline-block;_x000D_
  margin: 0 5px 0 5px;_x000D_
  text-align: center;_x000D_
  text-decoration: none;_x000D_
  text-overflow: ellipsis;_x000D_
  white-space: nowrap;_x000D_
  color: #000;_x000D_
}

<div class="app">_x000D_

Make sure you're using the correct SDK when compiling/running and also, make sure you use source/target 1.7.

The way to use the ellipsis or varargs inside the method is as if it were an array:

public void PrintWithEllipsis(String...setOfStrings) {
    for (String s : setOfStrings)
        System.out.println(s);
}

This method can be called as following:

obj.PrintWithEllipsis(); // prints nothing
obj.PrintWithEllipsis("first"); // prints "first"
obj.PrintWithEllipsis("first", "second"); // prints "first\nsecond"

Inside PrintWithEllipsis, the type of setOfStrings is an array of String. So you could save the compiler some work and pass an array:

String[] argsVar = {"first", "second"};
obj.PrintWithEllipsis(argsVar);

For varargs methods, a sequence parameter is treated as being an array of the same type. So if two signatures differ only in that one declares a sequence and the other an array, as in this example:

void process(String[] s){}
void process(String...s){}

then a compile-time error occurs.

Source: The Java Programming Language specification, where the technical term is variable arity parameter rather than the common term varargs.

also using http://php.net/error_get_last will not help you out, because mail() does not emmit its errors into this function.

Only way seems to be using a proper mailer, like already suggested above.

With this code you will be also able to get MacAddress in Android 6.0 also

public static String getMacAddr() {
    try {
        List <NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface nif: all) {
            if (!nif.getName().equalsIgnoreCase("wlan0")) continue;

            byte[] macBytes = nif.getHardwareAddress();
            if (macBytes == null) {
                return "";
            }

            StringBuilder res1 = new StringBuilder();
            for (byte b: macBytes) {
                //res1.append(Integer.toHexString(b & 0xFF) + ":");
                res1.append(String.format("%02X:", b));
            }

            if (res1.length() > 0) {
                res1.deleteCharAt(res1.length() - 1);
            }
            return res1.toString();
        }
    } catch (Exception ex) {}
    return "02:00:00:00:00:00";
}

EDIT 1. This answer got a bug where a byte that in hex form got a single digit, will not appear with a "0" before it. The append to res1 has been changed to take care of it.

Simply now in 2014 the input element having an id supports the function val('').

For the input -

<input type="file" multiple="true" id="File1" name="choose-file" />

This js clears the input element -

$("#File1").val('');

:%s/$/\*/g

should work and so should :%s/$/*/g.

Note that all of the class_exists, extensions_loaded, and function_exists only check the link between PHP and the memcache package.

To actually check whether memcache is installed you must either:

• know the OS platform and use shell commands to check whether memcache package is installed
• or test whether memcache connection can be established on the expected port

EDIT 2: OK, actually here's an easier complete solution:

if (class_exists('Memcache')) {
    $memcache = new Memcache;
    $isMemcacheAvailable = @$memcache->connect('localhost');
}
if ($isMemcacheAvailable) {
    //...
}

Outdated code below

EDIT: Actually you must force PHP to throw error on warnings first. Have a look at this SO question answer.

You can then test the connection via:

try {
    $memcache->connect('localhost');
} catch (Exception $e) {
    // well it's not here
}

I'm not super fond of the interval thingies. When I want to defer jquery, or anything actually, it usually goes something like this.

Start with:

<html>
 <head>
  <script>var $d=[];var $=(n)=>{$d.push(n)}</script>
 </head>

Then:

 <body>
  <div id="thediv"></div>

  <script>
    $(function(){
       $('#thediv').html('thecode');
    });
  </script>

  <script src="http://code.jquery.com/jquery-3.2.1.min.js" type="text/javascript"></script>

Then finally:

  <script>for(var f in $d){$d[f]();}</script>
 </body>
<html>

Or the less mind-boggling version:

<script>var def=[];function defer(n){def.push(n)}</script>
<script>
defer(function(){
   $('#thediv').html('thecode');
});
</script>
<script src="http://code.jquery.com/jquery-3.2.1.min.js" type="text/javascript"></script>
<script>for(var f in def){def[f]();}</script>

And in the case of async you could execute the pushed functions on jquery onload.

<script async onload="for(var f in def){def[f]();}" 
src="jquery.min.js" type="text/javascript"></script>

Alternatively:

function loadscript(src, callback){
  var script = document.createElement('script');
  script.src = src
  script.async = true;
  script.onload = callback;
  document.body.appendChild(script);
};
loadscript("jquery.min", function(){for(var f in def){def[f]();}});

Here is the sample MYSQL Stored Procedure with delimiter and how to call..

DELIMITER $$

DROP PROCEDURE IF EXISTS `sp_user_login` $$
CREATE DEFINER=`root`@`%` PROCEDURE `sp_user_login`(
  IN loc_username VARCHAR(255),
  IN loc_password VARCHAR(255)
)
BEGIN

  SELECT user_id,
         user_name,
         user_emailid,
         user_profileimage,
         last_update
    FROM tbl_user
   WHERE user_name = loc_username
     AND password = loc_password
     AND status = 1;

END $$

DELIMITER ;

and call by, mysql_connection specification and

$loginCheck="call sp_user_login('".$username."','".$password."');";

it will return the result from the procedure.

Try setting 'clientCredentialType' to 'Windows' instead of 'Ntlm'.

I think that this is what the server is expecting - i.e. when it says the server expects "Negotiate,NTLM", that actually means Windows Auth, where it will try to use Kerberos if available, or fall back to NTLM if not (hence the 'negotiate')

I'm basing this on somewhat reading between the lines of: Selecting a Credential Type

An efficient way to loop over an Array is the built-in array method .map()

For a 1-dimensional array it would look like this:

function HandleOneElement( Cuby ) {
   Cuby.dimension
   Cuby.position_x
   ...
}
cubes.map(HandleOneElement) ; // the map function will pass each element

for 2-dimensional array:

cubes.map( function( cubeRow ) { cubeRow.map( HandleOneElement ) } )

for an n-dimensional array of any form:

Function.prototype.ArrayFunction = function(param) {
  if (param instanceof Array) {
    return param.map( Function.prototype.ArrayFunction, this ) ;
  }
  else return (this)(param) ;
}
HandleOneElement.ArrayFunction(cubes) ;

I use layers to describe the architect or technology stack within a component of my solutions. I use tiers to logically group those components typically when network or interprocess communication is involved.

You can use ReSharper for namespace refactoring. It will give 30 days free trial. It will change namespace as per folder structure.

Steps:

1. Right click on the project/folder/files you want to refactor.

2. If you have installed ReSharper then you will get an option Refactor->Adjust Namespaces.... So click on this.

It will automatically change the name spaces of all the selected files.

So your array is structured like this (I'm gonna talk in pseudocode because my C#-fu is weak, but I hope you get the gist of what I'm saying)

string values[rows][columns]

So value[1][3] is the value at row 1, column 3.

You want to sort by column, so the problem is that your array is off by 90 degrees.

As a first cut, could you just rotate it?

std::string values_by_column[columns][rows];

for (int i = 0; i < rows; i++)
  for (int j = 0; j < columns; j++)
    values_by_column[column][row] = values[row][column]

sort_array(values_by_column[column])

for (int i = 0; i < rows; i++)
  for (int j = 0; j < columns; j++)
    values[row][column] = values_by_column[column][row]

If you know you only want to sort one column at a time, you could optimize this a lot by just extracting the data you want to sort:

  string values_to_sort[rows]
  for (int i = 0; i < rows; i++)
    values_to_sort[i] = values[i][column_to_sort]

  sort_array(values_to_sort)

  for (int i = 0; i < rows; i++)
    values[i][column_to_sort] = values_to_sort[i]

In C++ you could play tricks with how to calculate offsets into the array (since you could treat your two-dimensional array as a one-d array) but I'm not sure how to do that in c#.

With Underscore/Lodash:

General use case:

_.without(array, emptyVal, otherEmptyVal);
_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);

With empties:

_.without(['foo', 'bar', '', 'baz', '', '', 'foobar'], '');
--> ["foo", "bar", "baz", "foobar"]

See lodash documentation for without.

In my case, display: block was breaking the design as intended.

The max-width property just saved me.

and for styling, you can use text-overflow: ellipsis as well.

my code was

max-width: 255px
overflow:hidden

This is quite simple. Just follow these instruction which I am going to tell you:

Like you are having multiple activities, to go from one activity to another. You might be using the intent like this:

Intent i1 = new Intent(this, AnotherActivity);
startActivity(i1) 

You have just to add finish(); after starting the intent activity on each and every activity from start to end, for example,

Intent i1=new Intent(this, AnotherActivity);
startActivity(i1) 
finish();

So whenever you will click that exit button which is using finish() or System.exit(0) that must close your application completely.

assume series s

s = pd.Series(np.arange(100))

Get quantiles for [.1, .2, .3, .4, .5, .6, .7, .8, .9]

s.quantile(np.linspace(.1, 1, 9, 0))

0.1     9.9
0.2    19.8
0.3    29.7
0.4    39.6
0.5    49.5
0.6    59.4
0.7    69.3
0.8    79.2
0.9    89.1
dtype: float64

OR

s.quantile(np.linspace(.1, 1, 9, 0), 'lower')

0.1     9
0.2    19
0.3    29
0.4    39
0.5    49
0.6    59
0.7    69
0.8    79
0.9    89
dtype: int32

Both works fine. But according to the Apache docs you should avoid using mod_rewrite for simple redirections, and use Redirect instead. So according to them, you should preferably do:

<VirtualHost *:80>
    ServerName www.example.com
    Redirect / https://www.example.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.com
    # ... SSL configuration goes here
</VirtualHost>

The first / after Redirect is the url, the second part is where it should be redirected.

You can also use it to redirect URLs to a subdomain: Redirect /one/ http://one.example.com/

You can also refactor your code to use a generator. But this may not be a solution for all types of nested loops.

mysql -uroot -p -hslavedb.mydomain.com mydb_production -e "select * from users;"

From the usage printout:

-e, --execute=name
Execute command and quit. (Disables --force and history file)

The autoload config does start below the vendor dir. So you might want change the vendor dir, e.g.

{
    "config": {
        "vendor-dir": "../vendor/"
    },
    "autoload": {
        "psr-0": {"AppName": "src/"}
    }
}

Or isn't this possible in your project?

Had the same kind of problem and in fact the problem was not the function nor the function call, but what I passed as arguments to the function.

The function was called from the body of the script - the 'main' - so I passed "st1 a b" "st2 c d" "st3 e f" from the command line and passed it over to the function using myFunction $*

The $* causes the problem as it expands into a set of characters which will be interpreted in the call to the function using whitespace as a delimiter.

The solution was to change the call to the function in explicit argument handling from the 'main' towards the function : the call would then be myFunction "$1" "$2" "$3" which will preserve the whitespace inside strings as the quotes will delimit the arguments ... So if a parameter can contain spaces, it should be handled explicitly throughout all calls of functions.

As this may be the reason for long searches to problems, it may be wise never to use $* to pass arguments ...

Hope this helps someone, someday, somewhere ... Jan.

This is a very old question, but I found a new solution, so I wrote about it.

First of all, is this way of solution possible while using AutoGenerateColumns?

Yes, that can be done with AttachedProperty as follows.

<DataGrid AutoGenerateColumns="True" 
   local:DataGridOperation.DateTimeFormatAutoGenerate="yy-MM-dd"
   ItemsSource="{Binding}" />

AttachedProperty

There are two AttachedProperty defined that allow you to specify two formats. DateTimeFormatAutoGenerate for DateTime and TimeSpanFormatAutoGenerate for TimeSpan.

class DataGridOperation
{
    public static string GetDateTimeFormatAutoGenerate(DependencyObject obj) => (string)obj.GetValue(DateTimeFormatAutoGenerateProperty);
    public static void SetDateTimeFormatAutoGenerate(DependencyObject obj, string value) => obj.SetValue(DateTimeFormatAutoGenerateProperty, value);
    public static readonly DependencyProperty DateTimeFormatAutoGenerateProperty =

The other answers normalize an image based on the entire image. But if your image has a predominant color (such as black), it will mask out the features that you're trying to enhance since it will not be as pronounced. To get around this limitation, we can normalize the image based on a subsection region of interest (ROI). Essentially we will normalize based on the section of the image that we want to enhance instead of equally treating each pixel with the same weight. Take for instance this earth image:

Input image -> Normalization based on entire image

If we want to enhance the clouds by normalizing based on the entire image, the result will not be very sharp and will be over saturated due to the black background. The features to enhance are lost. So to obtain a better result we can crop a ROI, normalize based on the ROI, and then apply the normalization back onto the original image. Say we crop the ROI highlighted in green:

This gives us this ROI

The idea is to calculate the mean and standard deviation of the ROI and then clip the frame based on the lower and upper range. In addition, we could use an offset to dynamically adjust the clip intensity. From here we normalize the original image to this new range. Here's the result:

Before -> After

Code

import cv2
import numpy as np

# Load image as grayscale and crop ROI
image = cv2.imread('1.png', 0)
x, y, w, h = 364, 633, 791, 273
ROI = image[y:y+h, x:x+w]

# Calculate mean and STD
mean, STD  = cv2.meanStdDev(ROI)

# Clip frame to lower and upper STD
offset = 0.2
clipped = np.clip(image, mean - offset*STD, mean + offset*STD).astype(np.uint8)

# Normalize to range
result = cv2.normalize(clipped, clipped, 0, 255, norm_type=cv2.NORM_MINMAX)

cv2.imshow('image', image)
cv2.imshow('ROI', ROI)
cv2.imshow('result', result)
cv2.waitKey()

The difference between normalizing based on the entire image vs a specific section of the ROI can be visualized by applying a heatmap to the result. Notice the difference on how the clouds are defined.

Input image -> heatmap

Normalized on entire image -> heatmap

Normalized on ROI -> heatmap

Heatmap code

import matplotlib.pyplot as plt
import numpy as np
import cv2

image = cv2.imread('result.png', 0)
colormap = plt.get_cmap('inferno')
heatmap = (colormap(image) * 2**16).astype(np.uint16)[:,:,:3]
heatmap = cv2.cvtColor(heatmap, cv2.COLOR_RGB2BGR)

cv2.imshow('image', image)
cv2.imshow('heatmap', heatmap)
cv2.waitKey()

Note: The ROI bounding box coordinates were obtained using how to get ROI Bounding Box Coordinates without Guess & Check and heatmap code was from how to convert a grayscale image to heatmap image with Python OpenCV

Comments with REM

A REM can remark a complete line, also a multiline caret at the line end, if it's not the end of the first token.

REM This is a comment, the caret is ignored^
echo This line is printed

REM This_is_a_comment_the_caret_appends_the_next_line^
echo This line is part of the remark

REM followed by some characters .:\/= works a bit different, it doesn't comment an ampersand, so you can use it as inline comment.

echo First & REM. This is a comment & echo second

But to avoid problems with existing files like REM, REM.bat or REM;.bat only a modified variant should be used.

REM^;<space>Comment

And for the character ; is also allowed one of ;,:\/=

REM is about 6 times slower than :: (tested on Win7SP1 with 100000 comment lines).
For a normal usage it's not important (58µs versus 360µs per comment line)

Comments with ::

A :: always executes a line end caret.

:: This is also a comment^
echo This line is also a comment

Labels and also the comment label :: have a special logic in parenthesis blocks.
They span always two lines SO: goto command not working.
So they are not recommended for parenthesis blocks, as they are often the cause for syntax errors.

With ECHO ON a REM line is shown, but not a line commented with ::

Both can't really comment out the rest of the line, so a simple %~ will cause a syntax error.

REM This comment will result in an error %~ ...

But REM is able to stop the batch parser at an early phase, even before the special character phase is done.

@echo ON
REM This caret ^ is visible

You can use &REM or &:: to add a comment to the end of command line. This approach works because '&' introduces a new command on the same line.

Comments with percent signs %= comment =%

There exists a comment style with percent signs.

In reality these are variables but they are expanded to nothing.
But the advantage is that they can be placed in the same line, even without &.
The equal sign ensures, that such a variable can't exists.

echo Mytest
set "var=3"     %= This is a comment in the same line=%

The percent style is recommended for batch macros, as it doesn't change the runtime behaviour, as the comment will be removed when the macro is defined.

set $test=(%\n%
%=Start of code=% ^
echo myMacro%\n%
)

The best and simple way:

Convert(varchar, {EndTime} - {StartTime}, 108)

Just like Anri noted.
