According to the information from @naitsirhc, I wanted to find the official API documentation. Here are my finding and some sample code.

1. I created a matplotlib.Axes object by seaborn.scatterplot().
2. The ax.get_legend() will return a matplotlib.legned.Legend instance.
3. Finally, you call .remove() function to remove the legend from your plot.

ax = sns.scatterplot(......)
_lg = ax.get_legend()
_lg.remove()

If you check the matplotlib.legned.Legend API document, you won't see the .remove() function.

The reason is that the matplotlib.legned.Legend inherited the matplotlib.artist.Artist. Therefore, when you call ax.get_legend().remove() that basically call matplotlib.artist.Artist.remove().

In the end, you could even simplify the code into two lines.

ax = sns.scatterplot(......)
ax.get_legend().remove()

The problem

IE<=8 simply doesn't have an indexOf() method for arrays.

The solution

If you need indexOf in IE<=8, you should consider using the following polyfill, which is recommended at the MDN :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(searchElement, fromIndex) {
        var k;
        if (this == null) {
            throw new TypeError('"this" is null or not defined');
        }
        var o = Object(this);
        var len = o.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = +fromIndex || 0;
        if (Math.abs(n) === Infinity) {
            n = 0;
        }
        if (n >= len) {
            return -1;
        }
        k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
        while (k < len) {
            if (k in o && o[k] === searchElement) {
                return k;
            }
            k++;
        }
        return -1;
    };
}

Minified :

Array.prototype.indexOf||(Array.prototype.indexOf=function(r,t){var n;if(null==this)throw new TypeError('"this" is null or not defined');var e=Object(this),i=e.length>>>0;if(0===i)return-1;var a=+t||0;if(Math.abs(a)===1/0&&(a=0),a>=i)return-1;for(n=Math.max(a>=0?a:i-Math.abs(a),0);i>n;){if(n in e&&e[n]===r)return n;n++}return-1});

foreach (string s in sList)
{
    if (s.equals("ok"))
        return true;
}

return false;

Alternatively, if you need to do some other things after you've found the item:

bool found = false;
foreach (string s in sList)
{
    if (s.equals("ok"))
    {
        found = true;
        break; // get out of the loop
    }
}

// do stuff

return found;

uuid1() is guaranteed to not produce any collisions (under the assumption you do not create too many of them at the same time). I wouldn't use it if it's important that there's no connection between the uuid and the computer, as the mac address gets used to make it unique across computers.

You can create duplicates by creating more than 2¹⁴ uuid1 in less than 100ns, but this is not a problem for most use cases.

uuid4() generates, as you said, a random UUID. The chance of a collision is really, really, really small. Small enough, that you shouldn't worry about it. The problem is, that a bad random-number generator makes it more likely to have collisions.

This excellent answer by Bob Aman sums it up nicely. (I recommend reading the whole answer.)

Frankly, in a single application space without malicious actors, the extinction of all life on earth will occur long before you have a collision, even on a version 4 UUID, even if you're generating quite a few UUIDs per second.

There is a module called 'pdb' in python. At the top of your python script you do

import pdb
pdb.set_trace()

and you will enter into debugging mode. You can use 's' to step, 'n' to follow next line similar to what you would do with 'gdb' debugger.

Your problem is that log4j has not been initialized. It does not affect the outcome of you application in any way, so it's safe to ignore or just initialize Log4J, see: How to initialize log4j properly?

-save-temps

This is another good option to have in mind:

gcc -save-temps -c -o main.o main.c

main.c

#define INC 1

int myfunc(int i) {
    return i + INC;
}

and now, besides the normal output main.o, the current working directory also contains the following files:

• main.i is the desired prepossessed file containing:

  # 1 "main.c"
  # 1 "<built-in>"
  # 1 "<command-line>"
  # 31 "<command-line>"
  # 1 "/usr/include/stdc-predef.h" 1 3 4
  # 32 "<command-line>" 2
  # 1 "main.c"
  
  
  int myfunc(int i) {
      return i + 1;
  }
  

• main.s is a bonus :-) and contains the generated assembly:

      .file   "main.c"
      .text
      .globl  myfunc
      .type   myfunc, @function
  myfunc:
  .LFB0:
      .cfi_startproc
      pushq   %rbp
      .cfi_def_cfa_offset 16
      .cfi_offset 6, -16
      movq    %rsp, %rbp
      .cfi_def_cfa_register 6
      movl    %edi, -4(%rbp)
      movl    -4(%rbp), %eax
      addl    $1, %eax
      popq    %rbp
      .cfi_def_cfa 7, 8
      ret
      .cfi_endproc
  .LFE0:
      .size   myfunc, .-myfunc
      .ident  "GCC: (Ubuntu 8.3.0-6ubuntu1) 8.3.0"
      .section    .note.GNU-stack,"",@progbits
  

If you want to do it for a large number of files, consider using instead:

 -save-temps=obj

which saves the intermediate files to the same directory as the -o object output instead of the current working directory, thus avoiding potential basename conflicts.

The advantage of this option over -E is that it is easy to add it to any build script, without interfering much in the build itself.

Another cool thing about this option is if you add -v:

gcc -save-temps -c -o main.o -v main.c

it actually shows the explicit files being used instead of ugly temporaries under /tmp, so it is easy to know exactly what is going on, which includes the preprocessing / compilation / assembly steps:

/usr/lib/gcc/x86_64-linux-gnu/8/cc1 -E -quiet -v -imultiarch x86_64-linux-gnu main.c -mtune=generic -march=x86-64 -fpch-preprocess -fstack-protector-strong -Wformat -Wformat-security -o main.i
/usr/lib/gcc/x86_64-linux-gnu/8/cc1 -fpreprocessed main.i -quiet -dumpbase main.c -mtune=generic -march=x86-64 -auxbase-strip main.o -version -fstack-protector-strong -Wformat -Wformat-security -o main.s
as -v --64 -o main.o main.s

Tested in Ubuntu 19.04 amd64, GCC 8.3.0.

CMake predefined targets

CMake automatically provides a targets for the preprocessed file:

make help

shows us that we can do:

make main.i

and that target runs:

Preprocessing C source to CMakeFiles/main.dir/main.c.i
/usr/bin/cc    -E /home/ciro/bak/hello/main.c > CMakeFiles/main.dir/main.c.i

so the file can be seen at CMakeFiles/main.dir/main.c.i

Tested on cmake 3.16.1.

In options object you have used "=" sign to assign value to port but we have to use ":" to assign values to properties in object when using object literal to create an object i.e."{}" ,these curly brackets. Even when you use function expression or create an object inside object you have to use ":" sign. for e.g.:

    var rishabh = {
        class:"final year",
        roll:123,
        percent: function(marks1, marks2, marks3){
                      total = marks1 + marks2 + marks3;
                      this.percentage = total/3 }
                    };

john.percent(85,89,95);
console.log(rishabh.percentage);

here we have to use commas "," after each property. but you can use another style to create and initialize an object.

var john = new Object():
john.father = "raja";  //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string

Copy xampp_start.exe from your XAMPP install directory to C:\Users\YOUR USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.

Replace YOUR USERNAME with your username.

When I faced the same problem I resolved by creating a temporary text box above the password field and hide it

like this,

<form method="post" autocomplete="off" action="">
    <ul class="field-set">
    <li>
        <label>Username:</label>
        <input type="text" name="acct" id="username" maxlength="100" size="20">
    </li>
    <li>
        <label>Password:</label>
        <input type="text" style="display:none;">
        <input type="password" name="pswd" id="password" maxlength="16" size="20" >
    </li>
        ...
    </ul> </form>

It will make the username text field not to show any previously typed words in a drop down. Since there is no attribute like name, id for the input field <input type="text" style="display:none;"> it wouldn't send any extra parameters also.

I am Not sure this is a good practice, but it will resolve the issue.

For CSS inline style, this worked best for me.

The best solution is to use async Task. You should avoid async void for several reasons, one of which is composability.

If the method cannot be made to return Task (e.g., it's an event handler), then you can use SemaphoreSlim to have the method signal when it is about to exit. Consider doing this in a finally block.

It's the year 2015. The correct answer to this question at this point is to use CSS white-space: pre-line or white-space: pre-wrap. Clean and elegant. The lowest version of IE that supports the pair is 8.

https://css-tricks.com/almanac/properties/w/whitespace/

P.S. Until CSS3 become common you'd probably need to manually trim off initial and/or trailing white-spaces.

f = open('some_file.txt','r')
line_num = 0
search_phrase = "the dog barked"
for line in f.readlines():
    line_num += 1
    if line.find(search_phrase) >= 0:
        print line_num

EDIT 1.5 years later (after seeing it get another upvote): I'm leaving this as is; but if I was writing today would write something closer to Ash/suzanshakya's solution:

def line_num_for_phrase_in_file(phrase='the dog barked', filename='file.txt')
    with open(filename,'r') as f:
        for (i, line) in enumerate(f):
            if phrase in line:
                return i
    return -1

• Using with to open files is the pythonic idiom -- it ensures the file will be properly closed when the block using the file ends.
• Iterating through a file using for line in f is much better than for line in f.readlines(). The former is pythonic (e.g., would work if f is any generic iterable; not necessarily a file object that implements readlines), and more efficient f.readlines() creates an list with the entire file in memory and then iterates through it. * if search_phrase in line is more pythonic than if line.find(search_phrase) >= 0, as it doesn't require line to implement find, reads more easily to see what's intended, and isn't easily screwed up (e.g., if line.find(search_phrase) and if line.find(search_phrase) > 0 both will not work for all cases as find returns the index of the first match or -1).
• Its simpler/cleaner to wrap an iterated item in enumerate like for i, line in enumerate(f) than to initialize line_num = 0 before the loop and then manually increment in the loop. (Though arguably, this is more difficult to read for people unfamiliar with enumerate.)

See code like pythonista

<ul>
    @foreach (int aPromotion in @Enum.GetValues(typeof(UserPromotion)))
    {
        var currentPromotion = (int)Model.JobSeeker.Promotion;
        if ((currentPromotion & aPromotion) == aPromotion)
        {
        <li>@Html.DisplayFor(e => currentPromotion)</li>
        }
    }
</ul>

The problem with Kersnowski's approach is that when the cell is redrawn the changes made when it's selected/deselected will be gone. So I would move the changes into the cell itself, which means subclassing is required here. For example:

class ICComplaintCategoryCell: UITableViewCell {
    @IBOutlet var label_title: UILabel!
    @IBOutlet var label_checkmark: UILabel!

    override func layoutSubviews() {
        super.layoutSubviews()
        reload()
    }
    func reload() {
        if isSelected {
            contentView.backgroundColor = UIColor.red
        }
        else if isHighlighted{
            contentView.backgroundColor = UIColor.red
        }
        else {
            contentView.backgroundColor = UIColor.white
        }
    }
}

And in your table view delegate just call reload:

if let cell = self.table.cellForRowAtIndexPath(path) as? ICComplaintCategoryCell {
    cell.reload()
}

This's weird!

I tested the solutions both sizeThatFits: and [webView stringByEvaluatingJavaScriptFromString:@"document.body.scrollHeight"] are NOT working for me.

However, I found an interesting easy way to get the right height of webpage content. Currently, I used it in my delegate method scrollViewDidScroll:.

CGFloat contentHeight = scrollView.contentSize.height - CGRectGetHeight(scrollView.frame);

Verified in iOS 9.3 Simulator/Device, good luck!

EDIT:

Background: The html content is calculated by my string variable and HTTP content template, loaded by method loadHTMLString:baseURL:, no registered JS scripts there.

UPDATE for .NET 5!

The below applies on/after NOV2020 when .NET 5 is officially out.

(see quick terminology section below, not just the How-to's)

How-To (CLI)

Pre-requisites

• Download latest version of the .net 5 SDK. Link

Steps

1. Open a terminal (e.g: bash, command prompt, powershell) and in the same directory as your .csproj file enter the below command:

dotnet publish --output "{any directory}" --runtime {runtime} --configuration {Debug|Release} -p:PublishSingleFile={true|false} -p:PublishTrimmed={true|false} --self-contained {true|false}

example:

dotnet publish --output "c:/temp/myapp" --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true

How-To (GUI)

Pre-requisites

• If reading pre NOV2020: Latest version of Visual Studio Preview*
• If reading NOV2020+: Latest version of Visual Studio*

*In above 2 cases, the latest .net5 SDK will be automatically installed on your PC.

Steps

1. Right-Click on Project, and click Publish
   

2. Click Start and choose Folder target, click next and choose Folder

3. Enter any folder location, and click Finish

4. Click on Edit
   

5. Choose a Target Runtime and tick on Produce Single File and save.*

6. Click Publish

7. Open a terminal in the location you published your app, and run the .exe. Example:

A little bit of terminology

Target Runtime
See the list of RID's

Deployment Mode

• Framework Dependent means a small .exe file produced but app assumed .Net 5 is installed on the host machine
• Self contained means a bigger .exe file because the .exe includes the framework but then you can run .exe on any machine, no need for .Net 5 to be pre-installed. NOTE: WHEN USING SELF CONTAINED, ADDITIONAL DEPENDENCIES (.dll's) WILL BE PRODUCED, NOT JUST THE .EXE

Enable ReadyToRun compilation
TLDR: it's .Net5's equivalent of Ahead of Time Compilation (AOT). Pre-compiled to native code, app would usually boot up faster. App more performant (or not!), depending on many factors. More info here

Trim unused assemblies
When set to true, dotnet will generate a very lean and small .exe and only include what it needs. Be careful here. Example: when using reflection in your app you probably don't want to set this flag to true.

Microsoft Doc

Previous Post

UPDATE (31-OCT-2019)

For anyone that wants to do this via a GUI and:

• Is using Visual Studio 2019
• Has .NET Core 3.0 installed (included in latest version of Visual Studio 2019)
• Wants to generate a single file

Note

Notice the large file size for such a small application

You can add the "PublishTrimmed" property. The application will only include components that are used by the application. Caution: don't do this if you are using reflection

Publish again

You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings.

Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal round brackets).

f = cell(N, 1);
for i=1:N
   f{i} = strcat('f', num2str(i));
end

Interesting. The only thing I knew that had to do with programming and had POCO in it is the POCO C++ framework.

• The simple question to your answer is already answered a lot of times:

  /*
  LINES I WANT COMMENTED
  LINES I WANT COMMENTED
  LINES I WANT COMMENTED
  */
  

• From your question it sounds like you want to comment out a lot of code?? I would advise to use a repository(git/github) to manage your files instead of commenting out lines.

• My last advice would be to learn about javadoc if not already familiar because documenting your code is really important.

Note: In hindsight this was a quick and dirty answer, and may not work in all situations. To have a reliable solution, see Tim Down's answer (copy pasting that here as this answer is still getting views and upvotes):

You can't do this reliably with the keyup event. If you want to know something about the character that was typed, you have to use the keypress event instead.

The following example will work all the time in most browsers but there are some edge cases that you should be aware of. For what is in my view the definitive guide on this, see http://unixpapa.com/js/key.html.

$("input").keypress(function(e) {
    if (e.which !== 0) {
        alert("Character was typed. It was: " + String.fromCharCode(e.which));
    }
});

keyup and keydown give you information about the physical key that was pressed. On standard US/UK keyboards in their standard layouts, it looks like there is a correlation between the keyCode property of these events and the character they represent. However, this is not reliable: different keyboard layouts will have different mappings.

The following was the original answer, but is not correct and may not work reliably in all situations.

To match the keycode with a word character (eg., a would match. space would not)

$("input").keyup(function(event)
{ 
    var c= String.fromCharCode(event.keyCode);
    var isWordcharacter = c.match(/\w/);
}); 

Ok, that was a quick answer. The approach is the same, but beware of keycode issues, see this article in quirksmode.

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

Usefetch and innerHTML to load div content

  dynamicPart.innerHTML = "Loading..."
  dynamicPart.innerHTML = await(await fetch(url)).text();
  setTimeout(refresh,2000);
}

Use the php extension Imagick. To control the desired size of the raster output image, use the setResolution function

<?php    
$im = new Imagick();
$im->setResolution(300, 300);     //set the resolution of the resulting jpg
$im->readImage('file.pdf[0]');    //[0] for the first page
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

(Extension on Paolo Bergantino his answer and Luis Melgratti his comment. You need to set the resolution before loading the image.)

I was having this AlertDialog theme related issue using sdk 1.6 as described here: http://markmail.org/message/mj5ut56irkrkc4nr

I solved the issue by doing the following:

  new AlertDialog.Builder(
  new ContextThemeWrapper(context, android.R.style.Theme_Dialog))

Hope this helps.

We can use zPosition in ios

if we have a view named salonDetailView eg : @IBOutlet weak var salonDetailView: UIView!

In my case see the image

and have UIView for GMSMapView eg : @IBOutlet weak var mapViewUI: GMSMapView!

To show the View salonDetailView upper of the mapViewUI

use zPosition as below

salonDetailView.layer.zPosition = 1

try this

the solution is, work with callbacks like this

$(function() {

    var jForm = $('form[name=form]');
    var jPWField = $('#employee_password');

    function getCheckedState() {
        return jForm.data('checked_state');
    };

    function setChecked(s) {
        jForm.data('checked_state', s);
    };


    jPWField.change(function() {
        //reset checked thing
        setChecked(null);
    }).trigger('change');

    jForm.submit(function(){
        switch(getCheckedState()) {
            case 'valid':
                return true;
            case 'invalid':
                //invalid, don submit
                return false;
            default:
                //make your check
                var password = $.trim(jPWField.val());

                $.ajax({
                    type: "POST",
                    async: "false",
                    url: "checkpass.php",
                    data: {
                        "password": $.trim(jPWField.val);
                    }
                    success: function(html) {
                        var arr=$.parseJSON(html);
                        setChecked(arr == "Successful" ? 'valid': 'invalid');
                        //submit again
                        jForm.submit();
                    }
                    });
                return false;
        }

    });
 });

one more, after you create user by following cmd-1, please assign read/write/root role to the user by cmd-2. then restart mongodb by cmd "mongod --auth".

The benefit of assign role to the user is you can do read/write operation by mongo shell or python/java and so on, otherwise you will meet "pymongo.errors.OperationFailure: not authorized" when you try to read/write your db.

cmd-1:

use admin
db.createUser({
  user: "newUsername",
  pwd: "password",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})

cmd-2:

db.grantRolesToUser('newUsername',[{ role: "root", db: "admin" }])

In android-N, this feature is included in it. check Number-blocking update for android N

Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

advantage of are:

1. Numbers blocked on calls are also blocked on texts
2. Blocked numbers can persist across resets and devices through the Backup & Restore feature
3. Multiple apps can use the same blocked numbers list

For more information, see android.provider.BlockedNumberContract

Update an existing project.

To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).

Open the build.gradle file for your module and update the values as follows:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0 rc1
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

Although the question is solved, sharing knowledge for clarification of the correct meaning of the error.

The error says that the parameter needed to the concerned breaking function is not in the required format i.e. string or Buffer

The solution is to change the parameter to string

breakingFunction(JSON.stringify(offendingParameter), ... other params...);

or buffer

breakingFunction(BSON.serialize(offendingParameter), ... other params...);

I sometimes use (in Load)

this.BeginInvoke((MethodInvoker) delegate {
  // some code
});

or

this.BeginInvoke((MethodInvoker) this.SomeMethod);

(change "this" to your form variable if you are handling the event on an instance other than "this").

This pushes the invoke onto the windows-forms loop, so it gets processed when the form is processing the message queue.

The Control.Invoke/Control.BeginInvoke methods are intended for use with threading, and are a mechanism to push work onto the UI thread. Normally this is used by worker threads etc. Control.Invoke does a synchronous call, where-as Control.BeginInvoke does an asynchronous call.

Normally, these would be used as:

SomeCodeOrEventHandlerOnAWorkerThread()
{
  // this code running on a worker thread...
  string newText = ExpensiveMethod(); // perhaps a DB/web call

  // now ask the UI thread to update itself
  this.Invoke((MethodInvoker) delegate {
      // this code runs on the UI thread!
      this.Text = newText;
  });
}

It does this by pushing a message onto the windows message queue; the UI thread (at some point) de-queues the message, processes the delegate, and signals the worker that it completed... so far so good ;-p

OK; so what happens if we use Control.Invoke / Control.BeginInvoke on the UI thread? It copes... if you call Control.Invoke, it is sensible enough to know that blocking on the message queue would cause an immediate deadlock - so if you are already on the UI thread it simply runs the code immediately... so that doesn't help us...

But Control.BeginInvoke works differently: it always pushes work onto the queue, even it we are already on the UI thread. This makes a really simply way of saying "in a moment", but without the inconvenience of timers etc (which would still have to do the same thing anyway!).

After much deliberation, engineering has removed this feature. The file /etc/launchd.conf was intentionally removed for security reasons. As a workaround, you could run launchctl limit as root early during boot, perhaps from a LaunchDaemon. (...)

Solution:

Put code in to /Library/LaunchDaemons/com.apple.launchd.limit.plist by bash-script:

#!/bin/bash

echo '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

        <key>ProgramArguments</key>
        <array>
                <string>/bin/launchctl</string>
                <string>limit</string>

The answers given above are good CRT answers, but if you want you can also use the Win32 solution to this. It's almost identical but IMO if you're programming for Windows you might as well just use its API (although I don't know if you are programming in Windows).

char* arrDayNames[7] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}; 
SYSTEMTIME st;
GetLocalTime(&st); // Alternatively use GetSystemTime for the UTC version of the time
printf("The current date and time are: %d/%d/%d %d:%d:%d:%d", st.wDay, st.wMonth, st.wYear, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds);
printf("The day is: %s", arrDayNames[st.wDayOfWeek]);

Anyway, this is a Windows solution. I hope it will be helpful for you sometime!

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

I had a Visual Studio 2013 installed, and it was running smoothly. At some point it started to get sluggish and decided to install Visual Studio 2015. After install, nothing changed and both versions were building the solution very slow (around 10 minutes for 18 projects in solution).

Then I have started thinking of recently installed extensions - the most recent installed was PHP tools for Visual Studio (had it on Visual Studio 2013 only). I am not sure how can an extension affect other versions of Visual Studio, but uninstalling it helped me to solve the problem.

I hope this will help others to realize that it is not always Visual Studio's fault.

There is clearly some confusion here as to what the preferred syntax for skipping a directory should be.

GNU Opinion

To ignore a directory and the files under it, use -prune

From the GNU find man page

Reasoning

-prune stops find from descending into a directory. Just specifying -not -path will still descend into the skipped directory, but -not -path will be false whenever find tests each file.

Issues with -prune

-prune does what it's intended to, but are still some things you have to take care of when using it.

1. find prints the pruned directory.

   • TRUE That's intended behavior, it just doesn't descend into it. To avoid printing the directory altogether, use a syntax that logically omits it.

2. -prune only works with -print and no other actions.

   • NOT TRUE. -prune works with any action except -delete. Why doesn't it work with delete? For -delete to work, find needs to traverse the directory in DFS order, since -deletewill first delete the leaves, then the parents of the leaves, etc... But for specifying -prune to make sense, find needs to hit a directory and stop descending it, which clearly makes no sense with -depth or -delete on.

Performance

I set up a simple test of the three top upvoted answers on this question (replaced -print with -exec bash -c 'echo $0' {} \; to show another action example). Results are below

----------------------------------------------
# of files/dirs in level one directories
.performance_test/prune_me     702702    
.performance_test/other        2         
----------------------------------------------

> find ".performance_test" -path ".performance_test/prune_me" -prune -o -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 23513814

> find ".performance_test" -not \( -path ".performance_test/prune_me" -prune \) -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 10670141

> find ".performance_test" -not -path ".performance_test/prune_me*" -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 864843145

Conclusion

Both f10bit's syntax and Daniel C. Sobral's syntax took 10-25ms to run on average. GetFree's syntax, which doesn't use -prune, took 865ms. So, yes this is a rather extreme example, but if you care about run time and are doing anything remotely intensive you should use -prune.

Note Daniel C. Sobral's syntax performed the better of the two -prune syntaxes; but, I strongly suspect this is the result of some caching as switching the order in which the two ran resulted in the opposite result, while the non-prune version was always slowest.

James' answer is correct, of course, but I should remind you that the whole ASMX thing is, if not obsolete, at least not the current method. I strongly suggest that you look into WCF, if only to avoid learning things you will need to forget.

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

Mikhail,

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

Good luck with your implementation.

this will be the appropriate solution for asked question:

String lineNumbers = AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER; EditorsUI.getPreferenceStore().setValue(lineNumbers, true);

You can't do this, which is by design. The Django framework authors intended a strict separation of presentation code from data logic. Filtering models is data logic, and outputting HTML is presentation logic.

So you have several options. The easiest is to do the filtering, then pass the result to render_to_response. Or you could write a method in your model so that you can say {% for object in data.filtered_set %}. Finally, you could write your own template tag, although in this specific case I would advise against that.

I'm facing same issue and resolving through

git add .

git commit -m "message"

git remote set-url origin https://[email protected]/aceofwings/RotairERP.git

then

git pull

#include <windows.h>
using namespace std;

// The directory path returned by native GetCurrentDirectory() no end backslash
string getCurrentDirectoryOnWindows()

    GetCurrentDirectory(maxDir, currentDir);
    return string(currentDir);
}

A way to find out old download links is to use internet archive tools like "Way back machine", https://archive.org/web/. You can browse older web pages versions and get the links you want.

For example, I needed to download the NDK rev 9, so I used this tool to access the NDK download page (https://developer.android.com/tools/sdk/ndk/) from March and the download link in March pointed to NDK rev 9.

Change Minute parameter to 0.

You can set the cron for every three hours as:

0 */3 * * * your command here ..

One simple solution:

cond1 <- df$sub == 1 & df$day == 2

cond2 <- df$sub == 3 & df$day == 4

df <- df[!(cond1 | cond2),]

The solution is actually a lot easier than any of the other suggestions:

std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();

Best of all, it's platform independent.

After trying all of the other solutions here without success, I skeptically tried the solution found in this article, and got it to work.

Essentially, it boils down to removing @charset "utf-8"; from your CSS.

This seems like a poor implementation in DreamWeaver - but it did fix the issue for me, regardless.

You can use an array

$something = array(
   'key' => 'value',
   'key2' => 'value2'
);

or with standard object.

$something = new StdClass();

$something->key = 'value';
$something->key2 = 'value2';

Actually the enhanced for loop should look like this

for (final Room room : rooms) {
          // Here your room is available
}

try out this....

$('#txtSearchProdAssign').keypress(function (e) {
 var key = e.which;
 if(key == 13)  // the enter key code
  {
    $('input[name = butAssignProd]').click();
    return false;  
  }
});   

$(function() {

  $('input[name="butAssignProd"]').click(function() {
    alert('Hello...!');
  });

  //press enter on text area..

  $('#txtSearchProdAssign').keypress(function(e) {
    var key = e.which;
    if (key == 13) // the enter key code
    {
      $('input[name = butAssignProd]').click();
      return false;
    }
  });

});

It's not so much the prime numbers themselves that are important, but the algorithms that work with primes. In particular, finding the factors of a number (any number).

As you know, any number has at least two factors. Prime numbers have the unique property in that they have exactly two factors: 1 and themselves.

The reason factoring is so important is mathematicians and computer scientists don't know how to factor a number without simply trying every possible combination. That is, first try dividing by 2, then by 3, then by 4, and so forth. If you try to factor a prime number--especially a very large one--you'll have to try (essentially) every possible number between 2 and that large prime number. Even on the fastest computers, it will take years (even centuries) to factor the kinds of prime numbers used in cryptography.

It is the fact that we don't know how to efficiently factor a large number that gives cryptographic algorithms their strength. If, one day, someone figures out how to do it, all the cryptographic algorithms we currently use will become obsolete. This remains an open area of research.

You can use from this for update in sql server

UPDATE
    T1
SET
   T1.col1 = T2.col1,
   T1.col2 = T2.col2
FROM
   Table1 AS T1
INNER JOIN Table2 AS T2
    ON T1.id = T2.id
WHERE
    T1.col3 = 'cool'

   UPDATE tbl_ClientNotes
    SET 
      ordering=ISNULL@ordering,ordering), 
      title=isnull(@title,title), 
      content=isnull(@content,content)
    WHERE id=@id

I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.

While the git fetch command will fetch down all the changes on the server that you don’t have yet, it will not modify your working directory at all. It will simply get the data for you and let you merge it yourself. However, there is a command called git pull which is essentially a git fetch immediately followed by a git merge in most cases.

The "s" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.SortableDateTimePattern property. The pattern reflects a defined standard (ISO 8601), and the property is read-only. Therefore, it is always the same, regardless of the culture used or the format provider supplied. The custom format string is "yyyy'-'MM'-'dd'T'HH':'mm':'ss".

When this standard format specifier is used, the formatting or parsing operation always uses the invariant culture.

A procedure for dividing integers that uses shifts and adds can be derived in straightforward fashion from decimal longhand division as taught in elementary school. The selection of each quotient digit is simplified, as the digit is either 0 and 1: if the current remainder is greater than or equal to the divisor, the least significant bit of the partial quotient is 1.

Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit.

In a classical arrangement, these two left shifts are combined into left shifting of one register pair. The upper half holds the current remainder, the lower half initial holds the dividend. As the dividend bits are transferred to the remainder register by left shift, the unused least significant bits of the lower half are used to accumulate the quotient bits.

Below is x86 assembly language and C implementations of this algorithm. This particular variant of a shift & add division is sometimes referred to as the "no-performing" variant, as the subtraction of the divisor from the current remainder is not performed unless the remainder is greater than or equal to the divisor. In C, there is no notion of the carry flag used by the assembly version in the register pair left shift. Instead, it is emulated, based on the observation that the result of an addition modulo 2ⁿ can be smaller that either addend only if there was a carry out.

You can use GCD to dispatch the scroll into the next iteration of main run loop in viewDidLoad to achieve this behavior. The scroll will be performed before the collection view is showed on screen, so there will be no flashing.

- (void)viewDidLoad {
    dispatch_async (dispatch_get_main_queue (), ^{
        NSIndexPath *indexPath = YOUR_DESIRED_INDEXPATH;
        [self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionCenteredHorizontally animated:NO];
    });
}

The question is: "Sort Collection". So you can't use Collections.sort(List<T> l, Comparator<? super T> comparator).

Some tips:

For Collection type:

Comparator<String> defaultComparator = new Comparator<String>() {
   @Override
   public int compare(String o1, String o2) {
       return o1.compareTo(o2);
   }
};

Collection<String> collection = getSomeStringCollection();
String[] strings = collection.toArray(new String[collection.size()]);
Arrays.sort(strings, defaultComparator);
List<String> sortedStrings = Arrays.asList(strings);

Collection<String> collection = getSomeStringCollection();
List<String> list = new ArrayList(collection);
Collections.sort(list, defaultComparator);
collection = list; // if you wish

For List type:

List<String> list = getSomeStringList();
Collections.sort(list, defaultComparator);

For Set type:

Set<String> set = getSomeStringSet();
// Than steps like in 'For Collection type' section or use java.util.TreeSet
// TreeSet sample:
// Sorted using java.lang.Comparable.
Set<String> naturalSorted = new TreeSet(set);

Set<String> set = getSomeStringSet();
Set<String> sortedSet = new TreeSet(defaultComparator);
sortedSet.addAll(set);

Java 8 version. There is java.util.List#sort(Comparator<? super E> c) method

List<String> list = getSomeStringList();
list.sort(defaultComparator);

or

List<String> list = getSomeStringList();
list.sort((String o1, String o2) -> o1.compareTo(o2));

or for types that implements Comparable:

List<String> list = getSomeStringList();
list.sort(String::compareTo);

In order to understand the trick, one has to know, how Adapters work in general and ArrayAdapter in particular.

Adapters: are objects that are able to bind data structures to widgets, then these widgets are displaying that data in a List or in a Spinner.

So the two questions an Adapter answers are:

1. Which widget or composite view needs to be associated with a data structure(your class' object) for a certain index?
2. How to extract the data from the data structure(your class' object) and how to set field(s) i.e EditText of the widget or composite view according to this data?

ArrayAdapter's answers are:

• Each widget (i.e row.xml OR android.R.layout.simple_spinner_item) for any index is the same, and is inflated from the resource whose ID was given to ArrayAdapter's constructor.
• Each widget is expected to be an instance of TextView (or descendant). The widget's .setText() method will be used with the string format of the item in the supporting data structure. The string format will be obtained by invoking .toString() on the item.

It works properly, I hope it is useful.

You can pass PHP arrays to JavaScript using json_encode PHP function.

<?php
    $phpArray = array(
        0 => "Mon", 
        1 => "Tue", 
        2 => "Wed", 
        3 => "Thu",
        4 => "Fri", 
        5 => "Sat",
        6 => "Sun",
    )
?>

<script type="text/javascript">

    var jArray = <?php echo json_encode($phpArray); ?>;

    for(var i=0; i<jArray.length; i++){
        alert(jArray[i]);
    }

 </script>

If you want an R solution, here's a small convenience function I sometimes use to find where the offending (multiByte) character is lurking. Note that it is the next character to what gets printed. This works because print will work fine, but substr throws an error when multibyte characters are present.

find_offending_character <- function(x, maxStringLength=256){  
  print(x)
  for (c in 1:maxStringLength){
    offendingChar <- substr(x,c,c)
    #print(offendingChar) #uncomment if you want the indiv characters printed
    #the next character is the offending multibyte Character
  }    
}

string_vector <- c("test", "Se\x96ora", "works fine")

lapply(string_vector, find_offending_character)

I fix that character and run this again. Hope that helps someone who encounters the invalid multibyte string error.

Use calendar.monthrange:

>>> from calendar import monthrange
>>> monthrange(2011, 2)
(1, 28)

Just to be clear, monthrange supports leap years as well:

>>> from calendar import monthrange
>>> monthrange(2012, 2)
(2, 29)

As @mikhail-pyrev mentions in a comment:

First number is weekday of first day of the month, second number is number of days in said month.

More succinct:

# Ruby
ruby -e 'puts open("random_numbers").map(&:to_i).reduce(:+)'

# Python
python -c 'print(sum(int(l) for l in open("random_numbers")))'

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

There are two ways(actually there are more) that you could do this.
1. using lxml
pip install lxml

from lxml import etree, objectify
from lxml.etree import XMLSyntaxError

def xml_validator(some_xml_string, xsd_file='/path/to/my_schema_file.xsd'):
    try:
        schema = etree.XMLSchema(file=xsd_file)
        parser = objectify.makeparser(schema=schema)
        objectify.fromstring(some_xml_string, parser)
        print "YEAH!, my xml file has validated"
    except XMLSyntaxError:
        #handle exception here
        print "Oh NO!, my xml file does not validate"
        pass

xml_file = open('my_xml_file.xml', 'r')
xml_string = xml_file.read()
xml_file.close()

xml_validator(xml_string, '/path/to/my_schema_file.xsd')

2. Use xmllint from the commandline. xmllint comes installed in many linux distributions.

>> xmllint --format --pretty 1 --load-trace --debug --schema /path/to/my_schema_file.xsd /path/to/my_xml_file.xml

Insert query doesn't support where keyword*

Conditions apply because you can use where condition for sub-select statements. You can perform complicated inserts using sub-selects.

For example:

INSERT INTO suppliers
(supplier_id, supplier_name)
SELECT account_no, name
FROM customers
WHERE city = 'Newark';

By placing a "select" in the insert statement, you can perform multiples inserts quickly.

With this type of insert, you may wish to check for the number of rows being inserted. You can determine the number of rows that will be inserted by running the following SQL statement before performing the insert.

SELECT count(*)
FROM customers
WHERE city = 'Newark';

You can make sure that you do not insert duplicate information by using the EXISTS condition.

For example, if you had a table named clients with a primary key of client_id, you could use the following statement:

INSERT INTO clients
(client_id, client_name, client_type)
SELECT supplier_id, supplier_name, 'advertising'
FROM suppliers
WHERE not exists (select * from clients
where clients.client_id = suppliers.supplier_id);

This statement inserts multiple records with a subselect.

If you wanted to insert a single record, you could use the following statement:

INSERT INTO clients
(client_id, client_name, client_type)
SELECT 10345, 'IBM', 'advertising'
FROM dual
WHERE not exists (select * from clients
where clients.client_id = 10345);

The use of the dual table allows you to enter your values in a select statement, even though the values are not currently stored in a table.

Very short answer :

Different databases have different uses. I'm not a database expert. Rule of thumb:

• if you are doing analytics (ex. aggregating historical data) use OLAP
• if you are doing transactions (ex. adding/removing orders on an e-commerce cart) use OLTP

Short answer:

Let's consider two example scenarios:

Scenario 1:

You are building an online store/website, and you want to be able to:

• store user data, passwords, previous transactions...
• store actual products, their associated prices

You want to be able to find data for a particular user, change its name... basically perform INSERT, UPDATE, DELETE operations on user data. Same with products, etc.

You want to be able to make transactions, possibly involving a user buying a product (that's a relation). Then OLTP is probably a good fit.

Scenario 2:

You have an online store/website, and you want to compute things like

• the "total money spent by all users"
• "what is the most sold product"

This falls into the analytics/business intelligence domain, and therefore OLAP is probably more suited.

If you think in terms of "It would be nice to know how/what/how much"..., and that involves all "objects" of one or more kind (ex. all the users and most of the products to know the total spent) then OLAP is probably better suited.

Longer answer:

Of course things are not so simple. That's why we have to use short tags like OLTPand OLAP in the first place. Each database should be evaluated independently in the end.

So what could be the fundamental difference between OLAP and OLTP?

Well, databases have to store data somewhere. It shouldn't be surprising that the way the data is stored heavily reflects the possible use of said data. Data is usually stored on a hard drive. Let's think of a hard drive as a really wide sheet of paper, where we can read and write things. There are two ways to organize our reads and writes so that they can be efficient and fast.

One way is to make a book that is a bit like a phone book. On each page of the book, we store the information regarding a particular user. Now that's nice, we can find the information for a particular user very easily! Just jump to the page! We can even have a special page at the beginning to tell us on which page the users are if we want. But on the other hand, if we want to find, say, how much money all of our users spent then we would have to read every page, i.e. the whole book! That would be a row-based book/database (OLTP). The optional page at the beginning would be the index.

Another way to use our big sheet of paper is to make an accounting book. I'm no accountant, but let's imagine that we would have a page for "expenditures", "purchases"... That's nice because now we can query things like "give me the total revenue" very quickly (just read the "purchases" page). We can also ask for more involved things like "give me the top ten products sold" and still have acceptable performance. But now consider how painful it would be to find the expenditures for a particular user. You would have to go through the whole list of everyone's expenditures and filter the ones of that particular user, then sum them. Which basically amounts to "read the whole book" again. That would be a column-based database (OLAP).

It follows that:

• OLTP databases are meant to be used to do many small transactions, and usually serve as a "single source of truth".

• OLAP databases on the other hand are more suited for analytics, data mining, fewer queries but they are usually bigger (they operate on more data).

It's a bit more involved than that of course and that's a 20 000 feet overview of how databases differ, but it allows me not to get lost in a sea of acronyms.

Speaking of acronyms:

• OLTP = Online transaction processing
• OLAP = Online analytical processing

To read a bit further, here are some relevant links which heavily inspired my answer:

• http://datawarehouse4u.info/OLTP-vs-OLAP.html
• http://www.ibmsystemsmag.com/Blogs/You-and-i/Archive/db-102-database-orientation-row-vs-column/

For those who are still having trouble with this, try separating the two lines as below.

override func viewDidLoad() {
    self.navigationController!.interactivePopGestureRecognizer!.delegate = self
    ...

override func viewWillAppear(_ animated: Bool) {
    self.navigationController!.interactivePopGestureRecognizer!.isEnabled = true
    ...

Obviously, in my app,

interactivePopGestureRecognizer!.isEnabled

got reset to false before the view was shown for some reason.

I think init_js should use declare instead of local!

function scan3() {
    declare -n outvar=$1    # -n makes it a nameref.
    local nl=$'\x0a'
    outvar="output${nl}${nl}"  # two total. quotes preserve newlines
}

As pointed out here you must use the script in the UMD subdirectory, in my case

        bundles.Add(new ScriptBundle("~/bundles/projectbundle").Include(
            "~/Scripts/umd/popper.js",
            "~/Scripts/bootstrap.js",
            "~/Scripts/respond.js",
            "~/Scripts/summernote-bs4.js"));

Specifically this: "~/Scripts/umd/popper.js",

res.erase(it) always returns the next valid iterator, if you erase the last element it will point to .end()

At the end of the loop ++it is always called, so you increment .end() which is not allowed.

Simply checking for .end() still leaves a bug though, as you always skip an element on every iteration (it gets 'incremented' by the return from .erase(), and then again by the loop)

You probably want something like:

 while (it != res.end()) {
        it = res.erase(it);    
 }

to erase each element

(for completeness: I assume this is a simplified example, if you simply want every element gone without having to perform an operation on it (e.g. delete) you should simply call res.clear())

When you only conditionally erase elements, you probably want something like

for ( ; it != res.end(); ) {
  if (condition) {
    it = res.erase(it);
  } else {
    ++it;
  }
}

You can find your solution from apple's DEMO in this page: WWDC 2013 , find out and download UIImageEffects sample code.

Then with @Jeremy Fox's code. I changed it to

- (UIImage*)getDarkBlurredImageWithTargetView:(UIView *)targetView
{
    CGSize size = targetView.frame.size;

    UIGraphicsBeginImageContext(size);
    CGContextRef c = UIGraphicsGetCurrentContext();
    CGContextTranslateCTM(c, 0, 0);
    [targetView.layer renderInContext:c]; // view is the view you are grabbing the screen shot of. The view that is to be blurred.
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return [image applyDarkEffect];
}

Hope this will help you.

The MessageBox in the Extended WPF Toolkit is very nice. It's at Microsoft.Windows.Controls.MessageBox after referencing the toolkit DLL. Of course this was released Aug 9 2011 so it would not have been an option for you originally. It can be found at Github for everyone out there looking around.

I'm not sure if this is what you had in mind, but I ended up on this question because I was unable to install node_modules inside my project dir as it was mounted on a filesystem that did not support symlinks (a VM "shared" folder).

I found the following workaround:

1. Copy the package.json file to a temp folder on a different filesystem
2. Run npm install there
3. Copy the resulting node_modules directory back into the project dir, using cp -r --dereference to expand symlinks into copies.

I hope this helps someone else who ends up on this question when looking for a way to move node_modules to a different filesystem.

Other options

There is another workaround, which I found on the github issue that @Charminbear linked to, but this doesn't work with grunt because it does not support NODE_PATH as per https://github.com/browserify/resolve/issues/136:

lets say you have /media/sf_shared and you can't install symlinks in there, which means you can't actually npm install from /media/sf_shared/myproject because some modules use symlinks.

• $ mkdir /home/dan/myproject && cd /home/dan/myproject
• $ ln -s /media/sf_shared/myproject/package.json (you can symlink in this direction, just can't create one inside of /media/sf_shared)
• $ npm install
• $ cd /media/sf_shared/myproject
• $ NODE_PATH=/home/dan/myproject/node_modules node index.js

Just add 360° if the answer from atan2 is less than 0°.

A Jmeter Test Plan must have listener to showcase the result of performance test execution.

• Listeners capture the response coming back from Server while Jmeter runs and showcase in the form of – tree, tables, graphs and log files.

• It also allows you to save the result in a file for future reference. There are many types of listeners Jmeter provides. Some of them are: Summary Report, Aggregate Report, Aggregate Graph, View Results Tree, View Results in Table etc.

Here is the detailed understanding of each parameter in Summary report.

By referring to the figure:

image

Label: It is the name/URL for the specific HTTP(s) Request. If you have selected “Include group name in label?” option then the name of the Thread Group is applied as the prefix to each label.

Samples: This indicates the number of virtual users per request.

Average: It is the average time taken by all the samples to execute specific label. In our case, the average time for Label 1 is 942 milliseconds & total average time is 584 milliseconds.

Min: The shortest time taken by a sample for specific label. If we look at Min value for Label 1 then, out of 20 samples shortest response time one of the sample had was 584 milliseconds.

Max: The longest time taken by a sample for specific label. If we look at Max value for Label 1 then, out of 20 samples longest response time one of the sample had was 2867 milliseconds.

Std. Dev.: This shows the set of exceptional cases which were deviating from the average value of sample response time. The lesser this value more consistent the data. Standard deviation should be less than or equal to half of the average time for a label.

Error%: Percentage of Failed requests per Label.

Throughput: Throughput is the number of request that are processed per time unit(seconds, minutes, hours) by the server. This time is calculated from the start of first sample to the end of the last sample. Larger throughput is better.

KB/Sec: This indicates the amount of data downloaded from server during the performance test execution. In short, it is the Throughput measured in Kilobytes per second.

It's worth investigating the Pipeline plugin. With the plugin you can checkout multiple VCS projects into relative directory paths. Beforehand creating a directory per VCS checkout. Then issue commands to the newly checked out VCS workspace. In my case I am using git. But you should get the idea.

node{
    def exists = fileExists 'foo'
    if (!exists){
        new File('foo').mkdir()
    }
    dir ('foo') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'bar'
    if (!exists){
        new File('bar').mkdir()
    }
    dir ('bar') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'baz'
    if (!exists){
        new File('baz').mkdir()
    }
    dir ('baz') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
}

/**
     * Method to detect presence of duplicates in a generic list. 
     * Depends on the equals method of the concrete type. make sure to override it as required.
     */
    public static <T> boolean hasDuplicates(List<T> list){
        int count = list.size();
        T t1,t2;

        for(int i=0;i<count;i++){
            t1 = list.get(i);
            for(int j=i+1;j<count;j++){
                t2 = list.get(j);
                if(t2.equals(t1)){
                    return true;
                }
            }
        }
        return false;
    }

An example of a concrete class that has overridden equals() :

public class Reminder{
    private long id;
    private int hour;
    private int minute;

    public Reminder(long id, int hour, int minute){
        this.id = id;
        this.hour = hour;
        this.minute = minute;
    }

    @Override
    public boolean equals(Object other){
        if(other == null) return false;
        if(this.getClass() != other.getClass()) return false;
        Reminder otherReminder = (Reminder) other;
        if(this.hour != otherReminder.hour) return false;
        if(this.minute != otherReminder.minute) return false;

        return true;
    }
}

If you want to use special character in javascript variable value, Escape Character (\) is required.

Backslash in your example is special character, too.

So you should do something like this,

var ttt = "aa ///\\\\\\"; // --> ///\\\

or

var ttt = "aa ///\\"; // --> ///\

But Escape Character not require for user input.

When you press / in prompt box or input field then submit, that means single /.

Simply speaking Unicode is a standard which assigned one number (called code point) to all characters of the world (Its still work in progress).

Now you need to represent this code points using bytes, thats called character encoding. UTF-8, UTF-16, UTF-6 are ways of representing those characters.

UTF-8 is multibyte character encoding. Characters can have 1 to 6 bytes (some of them may be not required right now).

UTF-32 each characters have 4 bytes a characters.

UTF-16 uses 16 bits for each character and it represents only part of Unicode characters called BMP (for all practical purposes its enough). Java uses this encoding in its strings.

check if you JAVA_HOME is set to 1.7 or below. because tomcat 7 is not compatible with jdk 1.8

This worked for me

Define a class for key definition in your group.

class KeyObj {

    ArrayList<Object> keys;

    public KeyObj( Object... objs ) {
        keys = new ArrayList<Object>();

        for (int i = 0; i < objs.length; i++) {
            keys.add( objs[i] );
        }
    }

    // Add appropriate isEqual() ... you IDE should generate this

}

Now in your code,

peopleByManyParams = people
            .collect(Collectors.groupingBy(p -> new KeyObj( p.age, p.other1, p.other2 ), Collectors.mapping((Person p) -> p, toList())));

Not exactly the same as NUnit's Value (or TestCase) attributes, but MSTest has the DataSource attribute, which allows you to do a similar thing.

You can hook it up to database or XML file - it is not as straightforward as NUnit's feature, but it does the job.

I'm not a mod_rewrite expert, I often struggle with it, but I have done this on one of my sites, it might need other flags etc depending on your circumstances. I'm using this:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteCond %{REQUEST_URI} !^/subdomains/subdomain
RewriteRule ^(.*)$ /subdomains/subdomain/$1 [L] 

Any other rewrite rules for the rest of the site must go afterwards to prevent them from interfering with your subdomain rewrites.

it doesn't work because you have not programmed a fail-safe into the code. java sees that the scanner can still collect input while there is input to be collected and if possible, while that is true, it keeps doing so. having a scanner test to see if a certain word, like EXIT for example, is fine, but you could also have it loop a certain number of times, like ten or so. but the most efficient approach is to ask the user of your program how many strings they wish to enter, and while the number of strings they enter is less than the number they put in, the program shall execute. an added option could be if they type EXIT, when they see they need less spaces than they put in and don't want to fill the next cells up with nothing but whitespace. and you could have the program ask if they want to enter more input, in case they realize they need to enter more data into the computer. the program would be quite simplistic to make, as well because there are a plethera of ways you could do it. feel free to ask me for these ways, i'm running out of room though. XD

Like pagination you can use below formule for taking slice of list or elements:

var slice = myList.Skip((pageNumber - 1) * pageSize)
                  .Take(pageSize);

Example 1: first five items

var pageNumber = 1;
var pageSize = 5;

Example 2: second five items

var pageNumber = 2;
var pageSize = 5;

Example 3: third five items

var pageNumber = 3;
var pageSize = 5;

If notice to formule parameters pageSize = 5 and pageNumber is changing, if you want to change number of items in slicing you change pageSize.

A #spacer div must be placed between the header and main body, like this:

<header>
</header>
<div id="spacer"></div>
<main>
</main>

The header's position will be fixed, while the spacer will keep its default static position:

header {position: fixed;}

Finally you need to make sure that both the header and spacer have the same size-related properties, like so:

header, #spacer {
    height: 100px;
    max-height: 35vh;
}

This works for me at least.

$("input[type='text'], textarea, input[type='password']").css({width: "90%"});

and while file-input is a bit different, you may want to include them too (eg. for visual consistency):

$("input[type='text'], textarea, input[type='password'], input[type='file']").css({width: "90%"});

Many cases can be implemented in both class types.

Interfaces are usefull when you want to define a class that has to have at least basic functions. Like a real interface for example USB.

interface USB {
    public function sendPower(); //charge iphone for example
    public function sendData(); //itunes
    public function recieveData();
}

Use abstract classes when there are several ways to to implement an object.

abstract class MobilePhone {
    public function isIphone();

    public function charge() {
        //get some power, all phones need that
    }
}

class iPhone extends MobilePhone {
    public function isIphone() { return true; }
}

It's because it's already null or undefined. Null or undefined does not have any type. You can check if it's is undefined first. In typescript (null == undefined) is true.

  if (uemail == undefined) {
      alert('undefined');
  } else {
      alert('defined');
  }

or

  if (uemail == null) {
      alert('undefined');
  } else {
      alert('defined');
  }

An important point is to consider if you perform tasks based on difference between 2 timestamps because you will get odd behavior if you generate it with gettimeofday(), and even clock_gettime(CLOCK_REALTIME,..) at the moment where you will set the time of your system.

To prevent such problem, use clock_gettime(CLOCK_MONOTONIC_RAW, &tms) instead.

You can try this:

SELECT TO_CHAR(dbms_lob.substr(BLOB_FIELD, 3900)) FROM TABLE_WITH_BLOB;

However, It would be limited to 4000 byte

Now we could also use:

if (Attachment != null  && Attachment.Any())

Any() is often easier to understand in a glance for the developer than checking Length() > 0. Also has very little difference with processing speed.

Short answer is: You don't have any choice other than:

arr[4] = 5;

1. Select columns A:H with A1 as the active cell.
2. Open Home ? Styles ? Conditional Formatting ? New Rule.
3. Choose Use a formula to determine which cells to format and supply one of the following formulas¹ in the Format values where this formula is true: text box.
   • To highlight the Account and Store Manager columns when one of the four dates is blank:
             =AND(LEN($A1), COLUMN()<3, COUNTBLANK($E1:$H1))
   • To highlight the Account, Store Manager and blank date columns when one of the four dates is blank:
             =AND(LEN($A1), OR(COLUMN()<3, AND(COLUMN()>4, COUNTBLANK(A1))), COUNTBLANK($E1:$H1))
4. Click [Format] and select a cell Fill.
5. Click [OK] to accept the formatting and then [OK] again to create the new rule. In both cases, the Applies to: will refer to =$A:$H.

Results should be similar to the following.

¹ _{The COUNTBLANK function was introduced with Excel 2007. It will count both true blanks and zero-length strings left by formulas (e.g. "").}

You're going to have to either use JS or write a function/method in whatever non-markup language you're using to do this. For instance you could write something that will save the status to a cookie or session variable then check for it on page load. If you want to do it without reloading the page then JS is going to be your only option.

Maybe late to the party but in my case it was RHEL 6.8:

Copy certificate.crt issued by hosting to:

/etc/pki/ca-trust/source/anchors/

Then:

update-ca-trust force-enable (ignore not found warnings)
update-ca-trust extract

Hope it helps

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

Here is the minimal change to the original proposal to create a valid daemon in Bourne shell (or Bash):

#!/bin/sh
if [ "$1" != "__forked__" ]; then
    setsid "$0" __forked__ "$@" &
    exit
else
    shift
fi

trap 'siguser1=true' SIGUSR1
trap 'echo "Clean up and exit"; kill $sleep_pid; exit' SIGTERM
exec > outfile
exec 2> errfile
exec 0< /dev/null

while true; do
    (sleep 30000000 &>/dev/null) &
    sleep_pid=$!
    wait
    kill $sleep_pid &>/dev/null
    if [ -n "$siguser1" ]; then
        siguser1=''
        echo "Wait was interrupted by SIGUSR1, do things here."
    fi
done

Explanation:

• Line 2-7: A daemon must be forked so it doesn't have a parent. Using an artificial argument to prevent endless forking. "setsid" detaches from starting process and terminal.
• Line 9: Our desired signal needs to be differentiated from other signals.
• Line 10: Cleanup is required to get rid of dangling "sleep" processes.
• Line 11-13: Redirect stdout, stderr and stdin of the script.
• Line 16: sleep in the background
• Line 18: wait waits for end of sleep, but gets interrupted by (some) signals.
• Line 19: Kill sleep process, because that is still running when signal is caught.
• Line 22: Do the work if SIGUSR1 has been caught.

Guess it does not get any simpler than that.

Update

As I continue to recieve upvotes on this, I think it is reasonable to remember that this answer is 4 years old. Web has grown in a really fast pace, so please be mindful about this answer.

I had the same issue recently and researched about the subject.

The solution given is called long polling, and to correctly use it you must be sure that your AJAX request has a "large" timeout and to always make this request after the current ends (timeout, error or success).

Long Polling - Client

Here, to keep code short, I will use jQuery:

function pollTask() { 

    $.ajax({

        url: '/api/Polling',
        async: true,            // by default, it's async, but...
        dataType: 'json',       // or the dataType you are working with
        timeout: 10000,          // IMPORTANT! this is a 10 seconds timeout
        cache: false

    }).done(function (eventList) {  

       // Handle your data here
       var data;
       for (var eventName in eventList) {

            data = eventList[eventName];
            dispatcher.handle(eventName, data); // handle the `eventName` with `data`

       }

    }).always(pollTask);

}

It is important to remember that (from jQuery docs):

In jQuery 1.4.x and below, the XMLHttpRequest object will be in an invalid state if the request times out; accessing any object members may throw an exception. In Firefox 3.0+ only, script and JSONP requests cannot be cancelled by a timeout; the script will run even if it arrives after the timeout period.

Long Polling - Server

It is not in any specific language, but it would be something like this:

function handleRequest () {  

     while (!anythingHappened() || hasTimedOut()) { sleep(2); }

     return events();

} 

Here, hasTimedOut will make sure your code does not wait forever, and anythingHappened, will check if any event happend. The sleep is for releasing your thread to do other stuff while nothing happens. The events will return a dictionary of events (or any other data structure you may prefer) in JSON format (or any other you prefer).

It surely solves the problem, but, if you are concerned about scalability and perfomance as I was when researching, you might consider another solution I found.

Solution

Use sockets!

On client side, to avoid any compatibility issues, use socket.io. It tries to use socket directly, and have fallbacks to other solutions when sockets are not available.

On server side, create a server using NodeJS (example here). The client will subscribe to this channel (observer) created with the server. Whenever a notification has to be sent, it is published in this channel and the subscriptor (client) gets notified.

If you don't like this solution, try APE (Ajax Push Engine).

Hope I helped.

 $.getJSON( "article.json", function(obj) {
  $.each(obj, function(key, value) {
         $("ul").append("<li>"+value.name+"'s age is : "+value.age+"</li>");
  });
 });
});

          fs.createReadStream("./jquery-3.2.0.min.js").pipe(response);
  } else if(request.method == 'GET' && request.url == '/app.js') {
          response.writeHead(200,{"Content-Type":"text/javascript"});
          fs.createReadStream("./app.js").pipe(response);
  }
  else if(request.method == 'GET' && request.url == '/article.json') {
          response.writeHead(200,{"Content-Type":"text/json"});
          fs.createReadStream("./article.json").pipe(response);
  }
}

http.createServer(onRequest).listen(2341);
console.log("Server is running ....");

Server.js will run a simple node http server in your local to process the data.

Note don't forget toa dd jQuery library in your folder structure and change the version number accordingly in server.js and index.html

This is my running one https://github.com/surya4/jquery-json.

You need to use AND statement in your formula

=IF(AND(IF(NOT(ISBLANK(Q2));TRUE;FALSE);Q2<=R2);"1";"0")

And if both conditions are met, return 1.

You could also add more conditions in your AND statement.

I would assume at the end of the day you want to consume the data in the ArrayNode by iterating it. For that:

Iterator<JsonNode> iterator = datasets.withArray("datasets").elements();
while (iterator.hasNext()) 
        System.out.print(iterator.next().toString() + " "); 

or if you're into streams and lambda functions:

import com.google.common.collect.Streams;
Streams.stream(datasets.withArray("datasets").elements())
    .forEach( item -> System.out.print(item.toString()) )

It can cause anything for example, my issue was caused for typo error on configuration files. Some of people says caused by certificate files, another group says caused by unmatched locals.

If you cant find any solution about your issue, remove postgres and reinstall it.This is the best solution.

To get the id from the wildcard match:

$('[id^=pick_]').click(_x000D_
  function(event) {_x000D_
_x000D_
    // Do something with the id # here: _x000D_
    alert('Picked: '+ event.target.id.slice(5));_x000D_
_x000D_
  }_x000D_
);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="pick_1">moo1</div>_x000D_
<div id="pick_2">moo2</div>_x000D_
<div id="pick_3">moo3</div>

There is no solution in ANSI SQL to use joins in deletes, AFAIK.

DELETE FROM Table1
WHERE Table1.id IN (SELECT Table2.id FROM Table2)

Later edit

Other solution (sometimes performing faster):

DELETE FROM Table1
WHERE EXISTS( SELECT 1 FROM Table2 Where Table1.id = Table2.id)

def dupe(str1):
    s=set(str1)

    return "".join(s)
str1='geeksforgeeks'
a=dupe(str1)
print(a)

works well if order is not important.

Change the "package source" in nuget to All

Details: None of the above helped in my case. My problem was that I restricted to only one private feed. Once I changed the "package source" to All, my problem was solved. I believe the crux of the matter is that my private pkg has a dependency on other pkgs from nuget.org.

I hope this can help someone

An Example with python3 and the requests library as mentioned by @leoluk:

pip install requests

Script req.py:

import requests

url='http://localhost'

# in case you need a session
cd = { 'sessionid': '123..'}

r = requests.get(url, cookies=cd)
# or without a session: r = requests.get(url)
r.content

Now,execute it and you will get the html source of localhost!

python3 req.py

<div id"content">
<div id"contentLeft"></div>
<div id"contentRight"></div>
</div> 

#content {
clear: both;
width: 950px;
padding-bottom: 10px;
background:#fff;
overflow:hidden;
}
#contentLeft {
float: left;
display:inline;
width: 630px;
margin: 10px;
background:#fff;
}
#contentRight {
float: right;
width: 270px;
margin-top:25px;
margin-right:15px;
background:#d7e5f7;
} 

Obviously you will need to adjust the size of the columns to suit your site as well as colours etc but that should do it. You also need to make sure that your ContentLeft and ContentRight widths do not exceed the Contents width (including margins).

These are the buttons UP/DOWN

I had this same problem, my solution:
In the web.config file :

<compilation debug="true>
had to be changed to

You should write your own stream manipulator

• http://www.two-sdg.demon.co.uk/curbralan/papers/WritingStreamManipulators.html

cout << multi(5) << "whatever" << "lolcat";

No string formatting:

>> print 'Foo',0
Foo 0

mysql> SELECT CAST(4 AS DECIMAL(4,3));
+-------------------------+
| CAST(4 AS DECIMAL(4,3)) |
+-------------------------+
|                   4.000 |
+-------------------------+
1 row in set (0.00 sec)

mysql> SELECT CAST('4.5s' AS DECIMAL(4,3));
+------------------------------+
| CAST('4.5s' AS DECIMAL(4,3)) |
+------------------------------+

1 row in set (0.00 sec)

mysql> SELECT CAST('a4.5s' AS DECIMAL(4,3));
+-------------------------------+
| CAST('a4.5s' AS DECIMAL(4,3)) |
+-------------------------------+
|                         0.000 |
+-------------------------------+
1 row in set, 1 warning (0.00 sec)

This works for me.

select * from tablename
order by cast(columnname as int) asc

Label lblSecret = ((Label)e.Row.FindControl("lblSecret"));

NOTE: history.pushState() is now supported - see other answers.

You cannot change the whole url without redirecting, what you can do instead is change the hash.

The hash is the part of the url that goes after the # symbol. That was initially intended to direct you (locally) to sections of your HTML document, but you can read and modify it through javascript to use it somewhat like a global variable.

If applied well, this technique is useful in two ways:

1. the browser history will remember each different step you took (since the url+hash changed)
2. you can have an address which links not only to a particular html document, but also gives your javascript a clue about what to do. That means you end up pointing to a state inside your web app.

To change the hash you can do:

document.location.hash = "show_picture";

To watch for hash changes you have to do something like:

window.onhashchange = function(){
    var what_to_do = document.location.hash;    
    if (what_to_do=="#show_picture")
        show_picture();
}

Of course the hash is just a string, so you can do pretty much what you like with it. For example you can put a whole object there if you use JSON to stringify it.

There are very good JQuery libraries to do advanced things with that.

Many commands are already attached to simple ctrl+[key], you can also do chorded keybinding like ctrl a+b.

(In case this is your first time reading about chorded keybindings: They work by not letting go of the ctrl key and pressing a second key after the first.)

I have my Emmet: Wrap with Abbreviation bound to ((ctrl) (w+a)).

In windows: File > Preferences > Keyboard Shortcuts ((ctrl) (k+s))> search for Wrap with Abbreviation > double-click > add your combonation.

For checking the Last Modified header, you can use httpie (docs).

Installation

pip install httpie --user

Usage

$ http -h https://martin-thoma.com/author/martin-thoma/ | grep 'Last-Modified\|Date'
Date: Fri, 06 Jan 2017 10:06:43 GMT
Last-Modified: Fri, 06 Jan 2017 07:42:34 GMT

The Date is important as this reports the server time, not your local time. Also, not every server sends Last-Modified (e.g. superuser seems not to do it).

Depending on what you need to do, automating TortoiseSVN may be a good solution. For example, the following will update a repository and close the TortoiseSVN window if there were no errors or conflicts:

TortoiseProc.exe /command:update /path:"c:\path\to\repo\" /closeonend:2

Starting from the answer given by @chaos, but with a few modifications:

• You should always use ORDER BY if you use LIMIT. There is no implicit order guaranteed for an RDBMS table. You may usually get rows in the order of the primary key, but you can't rely on this, nor is it portable.

• If you order by in the descending order, you don't need to know the number of rows in the table beforehand.

• You must give a correlation name (aka table alias) to a derived table.

Here's my version of the query:

SELECT `id`
FROM (
    SELECT `id`, `val`
    FROM `big_table`
    ORDER BY `id` DESC
    LIMIT $n
) AS t
WHERE t.`val` = $certain_number;

Multi column unique indexes do not work in MySQL if you have a NULL value in row as MySQL treats NULL as a unique value and at least currently has no logic to work around it in multi-column indexes. Yes the behavior is insane, because it limits a lot of legitimate applications of multi-column indexes, but it is what it is... As of yet, it is a bug that has been stamped with "will not fix" on the MySQL bug-track...

There really isn't a single "answer" to this question, but there are definitely some helpful concepts that can help you to come to a decision.

The first question that needs to be answered in your use case is "Do I want to use the system Python?" If you want to use the Python distributed with your operating system, then using the apt-get install method may be just fine. Depending on the operating system distribution method though, you still have to ask some more questions, such as "Do I want to install multiple versions of this package?" If the answer is yes, then it is probably not a good idea to use something like apt. Dpkg pretty much will just untar an archive at the root of the filesystem, so it is up to the package maintainer to make sure the package installs safely under very little assumptions. In the case of most debian packages, I would assume (someone can feel free to correct me here) that they simply untar and provide a top level package.

For example, say the package is "virtualenv", you'd end up with /usr/lib/python2.x/site-packages/virtualenv. If you install it with easy_install you'd get something like /usr/lib/python2.x/site-packages/virtualenv.egg-link that might point to /usr/lib/python2.x/site-packages/virtualenv-1.2-2.x.egg which may be a directory or zipped egg. Pip does something similar although it doesn't use eggs and instead will place the top level package directly in the lib directory.

I might be off on the paths, but the point is that each method takes into account different needs. This is why tools like virtualenv are helpful as they allow you to sandbox your Python libraries such that you can have any combination you need of libraries and versions.

Setuptools also allows installing packages as multiversion which means there is not a singular module_name.egg-link created. To import those packages you need to use pkg_resources and the __import__ function.

Going back to your original question, if you are happy with the system python and plan on using virtualenv and pip to build environments for different applications, then installing virtualenv and / or pip at the system level using apt-get seems totally appropriate. One word of caution though is that if you plan on upgrading your distributions Python, that may have a ripple effect through your virtualenvs if you linked back to your system site packages.

I should also mention that none of these options is inherently better than the others. They simply take different approaches. Using the system version is an excellent way to install Python applications, yet it can be a very difficult way to develop with Python. Easy install and setuptools is very convenient in a world without virtualenv, but if you need to use different versions of the same library, then it also become rather unwieldy. Pip and virtualenv really act more like a virtual machine. Instead of taking care to install things side by side, you just create an whole new environment. The downside here is that 30+ virtualenvs later you might have used up quite bit of diskspace and cluttered up your filesystem.

As you can see, with the many options it is difficult to say which method to use, but with a little investigation into your use cases, you should be able to find a method that works.

application/xml is seen by svn as binary type whereas text/xml as text file for which a diff can be displayed.

To store another value in select options:

$("#select").append('<option value="4">another</option>')

After Php 7.1, The accepted answer won't work for all types of relationships.

Because depending of type the relationship, Eloquent will return a Collection, a Model or Null. And in Php 7.1 count(null) will throw an error.

So, to check if the relation exist you can use:

For relationships single: For example hasOne and belongsTo

if(!is_null($model->relation)) {
   ....
}

For relationships multiple: For Example: hasMany and belongsToMany

if ($model->relation->isNotEmpty()) {
   ....
}

allow_url_fopen is generally set to On. If it is not On, then you can try two things.

1. Create an .htaccess file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.

   php_value allow_url_fopen On
   

2. Create a php.ini file (for update server php5.ini) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:

   allow_url_fopen = On;
   

I have personally tested the above solutions; they worked for me.

Since you're using VB.NET, you'll need the following code:

Dim newString As String = origString.Replace(vbCr, "").Replace(vbLf, "")

You could use escape characters (\r and \n) in C#, but these won't work in VB.NET. You have to use the equivalent constants (vbCr and vbLf) instead.

I took what you had, and added another X-Testing header

var config = {headers:  {
        'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
        'Accept': 'application/json;odata=verbose',
        "X-Testing" : "testing"
    }
};

$http.get("/test", config);

And in the Chrome network tab, I see them being sent.

You can execute shell script in two ways,either by using cron job or by writing a shell script

Lets assume your script name is "yourscript.sh"

First check the user permission of the script. use below command to check user permission of the script

ll script.sh

If the script is in root,then use below command

sudo crontab -e

Second if the script holds the user "ubuntu", then use below command

crontab -e

Add the following line in your crontab:-

55 23 * * * /path/to/yourscript.sh

Another way of doing this is to write a script and run it in the backgroud

Here is the script where you have to put your script name(eg:- youscript.sh) which is going to run at 23:55pm everyday

#!/bin/bash while true do /home/modassir/yourscript.sh sleep 1d done

save it in a file (lets name it "every-day.sh")

sleep 1d - means it waits for one day and then it runs again.

now give the permission to your script.use below command:-

chmod +x every-day.sh

now, execute this shell script in the background by using "nohup". This will keep executing the script even after you logout from your session.

use below command to execute the script.

nohup ./every-day.sh &

Note:- to run "yourscript.sh" at 23:55pm everyday,you have to execute "every-day.sh" script at exactly 23:55pm.

Read man sshd_config for more details, but you can use the AllowUsers directive in /etc/ssh/sshd_config to limit the set of users who can login.

e.g.

AllowUsers boris

would mean that only the boris user could login via ssh.

I had this problem several times and often I didn't do something obviously wrong with dependencies.

It's always a good idea to check if this 'not found' class is present in the final apk. If it is, like it happened in my cases, the problem usually is:

It's not that given class is not found, but it cannot be loaded because its super class is missing.

Check if class that you extend is available and then try to fix your build script or dependencies accordingly.

pixVals = list(pilImg.getdata())

output is a list of all RGB values from the picture:

[(248, 246, 247), (246, 248, 247), (244, 248, 247), (244, 248, 247), (246, 248, 247), (248, 246, 247), (250, 246, 247), (251, 245, 247), (253, 244, 247), (254, 243, 247)]

Simplest solution

If you only call print without any arguments, it will output a blank line.

print

You can pipe the output to a file like this (considering your example):

f = open('out.txt', 'w')
print 'First line' >> f
print >> f
print 'Second line' >> f
f.close()

Not only is it OS-agnostic (without even having to use the os package), it's also more readable than putting \n within strings.

Explanation

The print() function has an optional keyword argument for the end of the string, called end, which defaults to the OS's newline character, for eg. \n. So, when you're calling print('hello'), Python is actually printing 'hello' + '\n'. Which means that when you're calling just print without any arguments, it's actually printing '' + '\n', which results in a newline.

Alternative

Use multi-line strings.

s = """First line
    Second line
    Third line"""
f = open('out.txt', 'w')
print s >> f
f.close()

SET myParam = IFNULL(myParam, 0);

Explanation: IFNULL(expression_1, expression_2)

The IFNULL function returns expression_1 if expression_1 is not NULL; otherwise it returns expression_2. The IFNULL function returns a string or a numeric based on the context where it is used.

Since version 2.6: a more intuitive way is to use the com.fasterxml.jackson.annotation.JsonProperty annotation on the field:

@JsonProperty(access = Access.WRITE_ONLY)
private String myField;

Even if a getter exists, the field value is excluded from serialization.

JavaDoc says:

/**
 * Access setting that means that the property may only be written (set)
 * for deserialization,
 * but will not be read (get) on serialization, that is, the value of the property
 * is not included in serialization.
 */
WRITE_ONLY

In case you need it the other way around, just use Access.READ_ONLY.

try any of the following,

background-size: contain;
background-size: cover;
background-size: 100%;

.container{
    background-size: 100%;
}

You can disable the validation in the form.

LayoutInflater creates View objects based on layouts defined in XML. There are several different ways to use LayoutInflater, including creating custom Views, inflating Fragment views into Activity views, creating Dialogs, or simply inflating a layout file View into an Activity.

There are a lot of misconceptions about how the inflation process works. I think this comes from poor of the documentation for the inflate() method. If you want to learn about the inflate() method in detail, I wrote a blog post about it here:

https://www.bignerdranch.com/blog/understanding-androids-layoutinflater-inflate/

I found out that composer runs with the php-version /usr/bin/env finds first in $PATH, which is 7.1.33 in my case on MacOs. So shifting mamp's php to the beginning helped me here.

PHPVER=$(/usr/libexec/PlistBuddy -c "print phpVersion" ~/Library/Preferences/de.appsolute.mamppro.plist)

export PATH=/Applications/MAMP/bin/php/php${PHPVER}/bin:$PATH

I think there is a difference between max-age=0, must-revalidate and no-cache:

In the must-revalidate case the client is allowed to send a If-Modified-Since request and serve the response from cache if 304 Not Modified is returned.

In the no-cache case, the client must not cache the response, so should not use If-Modified-Since.

The best way to find the path is to do via code.

Using Swift, just paste the code below inside the function application in your AppDelegate.swift

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentsPath = paths.first as String
println(documentsPath)

For things like numbers (decimal points, commas in amounts), they are usually preferred in the specific culture.

A appropriate way to do this would be set it at the culture level (for German) like this:

Thread.CurrentThread.CurrentCulture.NumberFormat = new CultureInfo("de").NumberFormat;

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.

I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.

Heres another good comparison of individual characteristics of each protocol.

I am assuming that you are making a web app because you refer to Apache and Node. Quick answer - Is it possible - YES. Is it recommended - NO. Node bundles it's own webserver and most websites run on port 80. I am also assuming that there is currently no Apache plugin which is supported by Nodejs and I am not sure if creating a virtual host is the best way to implement this. These are the questions that should be answered by developers who maintain Nodejs like the good folks at Joyent.

Instead of ports, it would be better to evaluate Node's tech stack which is completely different from most others and which is why I love it but it also involves a few compromises that you should be aware of in advance.

Your example looks similar to a CMS or a sharing web app and there are hundreds of out of the box apps available that will run just fine on Apache. Even if you do not like any readymade solution, you could write a webapp in PHP / Java / Python or mix n match it with a couple of ready made apps and they are all designed and supported to run behind a single instance of Apache.

It's time to pause and think about what I just said.

Now you are ready to decide on which techstack you are going to use. If your website will never use any out of the thousands of ready made apps that require Apache, then go for Node otherwise you must first eliminate the assumptions that I have stated earlier.

In the end, your choice of techstack is way more important than any individual component.

I completely agree with @Straseus that it is relatively trivial to use node.js file system api for handling uploads and downloads but think more about what you want from your website in the long run and then choose your techstack.

Learning Node's framework is easier than learning other frameworks but it is not a panacea. With a slightly more effort (which may be a worthwhile endeavor in itself), you can learn any other framework too. We all learn from each other and you will be more productive if you are working as a small team than if you are working alone and your backend technical skills will also develop faster. Therefore, do not discount the skills of other members of your team so cheaply.

This post is about a year old and chances are that you have already decided but I hope that my rant will help the next person who is going through a similar decision.

Thanks for reading.

You can create it easily:

$structure = './depth1/depth2/depth3/';
if (!mkdir($structure, 0, true)) {
die('Failed to create folders...');
}

In my case, the problem was in vscode.

I use windows and installed Ubuntu on my computer, so vscode terminal uses the Ubuntu. I just go to settings.json and change to cmd.exe again

If you cannot install aditional applications, then you can telnet (you will need to install this feature for your windows 7 by following this) the remote server:

TELNET server_name 80

followed by:

HEAD /virtual/directory/file.ext

or

GET /virtual/directory/file.ext

depending on if you want just the header (HEAD) or the full contents (GET)

If you already have the jquery object in a variable, you can also just treat it as a normal indexed array, without the use of jquery:

var all_rows = $("tr");
for(var i=0; i < all_rows.length; i++){
   var row = all_rows[i];
   //additionally, you can use it again in a jquery selector
   $(row).css("background-color","black");
}

Although the above example is not useful in any way, it is representing how you can treat objects created by jquery as indexed arrays.

In this case you use -1.

Why not use a generator instead?

private IEnumerable<string> ReadLogLines(string logPath) {
    using(StreamReader reader = File.OpenText(logPath)) {
        string line = "";
        while((line = reader.ReadLine()) != null) {
            yield return line;
        }
    }
}

Then you can use it like you would use the list:

var logFile = ReadLogLines(LOG_PATH);
foreach(var s in logFile) {
    // Do whatever you need
}

Of course, if you need to have a List<string>, then you will need to keep the entire file contents in memory. There's really no way around that.

 updateTypeahead(this)

will not pass DOM element to the function updateTypeahead(this). Here this will refer to the scope. If you want to access the DOM element use updateTypeahead($event). In the callback function you can get the DOM element by event.target.

Please Note : ng-change function doesn't allow to pass $event as variable.

There are a couple of things wrong in this code:

1. You're using <input> the wrong way. You should use a <label> if you want to make the text behind it clickable.
2. It's setting the enabled attribute, which does not exist. Use disabled instead.
3. If it would be an attribute, it's value should not be false, use disabled="disabled" or simply disabled without a value.
4. If checking for someone clicking on a form event that will CHANGE it's value (like check-boxes and radio-buttons), use .change() instead.

I'm not sure what your code is supposed to do. My guess is that you want to disable the input field with class roomNumber once someone selects "Walk in" (and possibly re-enable when deselected). If so, try this code:

HTML:

<form class="type">
    <p>
        <input type="radio" name="type" checked="checked" id="guest" value="guest" />
        <label for="guest">In House</label>
    </p>
    <p>
        <input type="radio" name="type" id="walk_in" value="walk_in" />
        <label for="walk_in">Walk in</label>
    </p>
    <p>
        <input type="text" name="roomnumber" class="roomNumber" value="12345" />
    </p>
</form>

Javascript:

$("form input:radio").change(function () {
    if ($(this).val() == "walk_in") {
        // Disable your roomnumber element here
        $('.roomNumber').attr('disabled', 'disabled');
    } else {
        // Re-enable here I guess
        $('.roomNumber').removeAttr('disabled');
    }
});

I created a fiddle here: http://jsfiddle.net/k28xd/1/

The object doesn't have 30 properties. It has one, which is an array that has 30 elements. You need the number of elements in that array.

You can also just use the @{ } block to create functions:

@{
    async Task<string> MyAsyncString(string input)
    {
        return Task.FromResult(input);
    }
}

Then later in your razor page:

   <div>@(await MyAsyncString("weee").ConfigureAwait(false))</div>

string strHeader = Request.Headers["XYZComponent"]
bool bHeader = Boolean.TryParse(strHeader, out bHeader ) && bHeader;

if "true" than true
if "false" or anything else ("fooBar") than false

or

string strHeader = Request.Headers["XYZComponent"]
bool b;
bool? bHeader = Boolean.TryParse(strHeader, out b) ? b : default(bool?);

if "true" than true
if "false" than false
else ("fooBar") than null

You can fill your data table like the below code.I am also fetching the connections at runtime using a predefined XML file that has all the connection.

  public static DataTable Execute_Query(string connection, string query)
    {
        Logger.Info("Execute Query has been called for connection " + connection);
        connection = "Data Source=" + Connections.run_singlevalue(connection, "server") + ";Initial Catalog=" + Connections.run_singlevalue(connection, "database") + ";User ID=" + Connections.run_singlevalue(connection, "username") + ";Password=" + Connections.run_singlevalue(connection, "password") + ";Connection Timeout=30;";
        DataTable dt = new DataTable();
        try
        {
            using (SqlConnection con = new SqlConnection(connection))
            {
                using (SqlCommand cmd = new SqlCommand(query, con))
                {
                    con.Open();
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        da.SelectCommand.CommandTimeout = 1800;
                        da.Fill(dt);
                    }
                    con.Close();
                }
            }
            Logger.Info("Execute Query success");
            return dt;
        }
        catch (Exception ex)
        {
            Console.Write(ex.Message);
            return null;
        }
    }   

In .NET 5.0 and later you can use the Convert.ToHexString() method.

using System;
using System.Text;

string value = "Hello world";

byte[] bytes = Encoding.UTF8.GetBytes(value);

string hexString = Convert.ToHexString(bytes);

Console.WriteLine($"String value: \"{value}\"");
Console.WriteLine($"   Hex value: \"{hexString}\"");

Running the above example code, you would get the following output:

String value: "Hello world"
   Hex value: "48656C6C6F20776F726C64"

Have a look at the below code snippet.

@RequestMapping(value="/Add/{type}")
public ModelAndView addForm(@PathVariable String type ){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("addContent");
    modelAndView.addObject("typelist",contentPropertyDAO.getType() );
    modelAndView.addObject("property",contentPropertyDAO.get(type,0) );
    return modelAndView;
}

Hope it helps in constructing your code.

I will explain to you with example.
Let A, B, C be 3 successive commits. Commit B contains a file that should not have been committed.

git log  # take A commit_id
git rebase -i "A_commit_ID" # do an interactive rebase
change commit to 'e' in rebase vim # means commit will be edited
git rm unwanted_file
git rebase --continue
git push --force-with-lease <branchName>    

Rails has an except/except! method that returns the hash with those keys removed. If you're already using Rails, there's no sense in creating your own version of this.

class Hash
  # Returns a hash that includes everything but the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false, c: nil}
  #
  # This is useful for limiting a set of parameters to everything but a few known toggles:
  #   @person.update(params[:person].except(:admin))
  def except(*keys)
    dup.except!(*keys)
  end

  # Replaces the hash without the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except!(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false }
  def except!(*keys)
    keys.each { |key| delete(key) }
    self
  end
end

You are probably using Windows, so new line is CR + LF (carriage return + line feed). So solution would be:

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="dummy.xsl"?>
  <item>
     <summary>Tootsie roll tiramisu macaroon wafer carrot cake.&#13;&#10;Danish topping sugar plum tart bonbon caramels cake.
     </summary>
  </item>

For Linux there is only LF and for Mac OS only CR.

In question there showed Linux way.

As others have pointed out, output can be buffered within your program before a console or shell has a chance to see it.

On unix-like systems, including macs, stdout has line-based buffering by default. This means that your program empties its stdout buffer as soon as it sees a newline.

However, on windows, newlines are no longer special, and full buffering is used. Windows doesn't support line buffering at all; see the msdn page on setvbuf.

So on windows, a good approach is to completely shut off stdout buffering like so:

setvbuf (stdout, NULL, _IONBF, 0);

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

There is a great book called Chaos and Fractals that has simple example code at the end of each chapter that implements some fractal or other example. A long time ago when I read that book, I converted each sample program (in some Basic dialect) into a Java applet that runs on a web page. The applets are here: http://hewgill.com/chaos-and-fractals/

One of the samples is a simple Mandelbrot implementation.

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Relative to what, your application ? If so then you can simply get the applications current Path with :

System.Environment.CurrentDirectory 

And append it to the connection string

I had the same ERROR message. tbrisker's solution did not work in my case. Instead this solved the issue:

$ python3 -m venv .env

Modify your web.config to display the server error details:

<system.web>
  <customErrors mode="Off" />
</system.web>

You may also need to remove/comment out the follow httpErrors section

  <system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404" />
      <error statusCode="404" path="/Error/Error404" responseMode="ExecuteURL" />
      <remove statusCode="500" />
      <error statusCode="500" path="/Error/Error500" responseMode="ExecuteURL" />
      <remove statusCode="403" />
      <error statusCode="403" path="/Error/Error403" responseMode="ExecuteURL" />
    </httpErrors>
  </system.webServer>

From my experience if you directly have a server error, this may be caused from an assembly version mismatch.

Check what is declared in the web.config and the actual ddl in the bin folder's project.

My solution is based on @marc_s solution, i just concatenated columns in cases that a constraint is based on more than one column:

SELECT
   FK.[name] AS ForeignKeyConstraintName
  ,SCHEMA_NAME(FT.schema_id) + '.' + FT.[name] AS ForeignTable
  ,STUFF(ForeignColumns.ForeignColumns, 1, 2, '') AS ForeignColumns
  ,SCHEMA_NAME(RT.schema_id) + '.' + RT.[name] AS ReferencedTable
  ,STUFF(ReferencedColumns.ReferencedColumns, 1, 2, '') AS ReferencedColumns
FROM
  sys.foreign_keys FK
  INNER JOIN sys.tables FT
  ON FT.object_id = FK.parent_object_id
  INNER JOIN sys.tables RT
  ON RT.object_id = FK.referenced_object_id
  CROSS APPLY
  (
    SELECT
      ', ' + iFC.[name] AS [text()]
    FROM
      sys.foreign_key_columns iFKC
      INNER JOIN sys.columns iFC
      ON iFC.object_id = iFKC.parent_object_id
        AND iFC.column_id = iFKC.parent_column_id
    WHERE
      iFKC.constraint_object_id = FK.object_id
    ORDER BY
      iFC.[name]
    FOR XML PATH('')
  ) ForeignColumns (ForeignColumns)
  CROSS APPLY
  (
    SELECT
      ', ' + iRC.[name]AS [text()]
    FROM
      sys.foreign_key_columns iFKC
      INNER JOIN sys.columns iRC
      ON iRC.object_id = iFKC.referenced_object_id
        AND iRC.column_id = iFKC.referenced_column_id
    WHERE
      iFKC.constraint_object_id = FK.object_id
    ORDER BY
      iRC.[name]
    FOR XML PATH('')
  ) ReferencedColumns (ReferencedColumns)

The EOF token must be at the beginning of the line, you can't indent it along with the block of code it goes with.

If you write <<-EOF you may indent it, but it must be indented with Tab characters, not spaces. So it still might not end up even with the block of code.

Also make sure you have no whitespace after the EOF token on the line.

It's not clear what you're actually trying to achieve, but here are two alternatives:

class E
{
public:
    struct X
    {
        int v;
    };

    // 1. (a) Instantiate an 'X' within 'E':
    X x;
};

int main()
{
    // 1. (b) Modify the 'x' within an 'E':
    E e;
    e.x.v = 9;

    // 2. Instantiate an 'X' outside 'E':
    E::X x;
    x.v = 10;
}

What about .GlobalEnv$a <- "new" ? I saw this explicit way of creating a variable in a certain environment here: http://adv-r.had.co.nz/Environments.html. It seems shorter than using the assign() function.

Try this, may not be the best way. but it works

String str = "5 * x^3 - 6 * x^1 + 1";
str = str.replaceAll("(?x)(\\d+)(\\s+?\\*?\\s+?)(\\w+?)(\\^+?)(\\d+?)", "$1$3<sup>$5</sup>");
System.out.println(str);

This has worked for me:

let webApiUrl = 'example.com/getStuff';
let tokenStr = 'xxyyzz';
axios.get(webApiUrl, { headers: {"Authorization" : `Bearer ${tokenStr}`} });

steps to install maven :

1. download the maven file from http://maven.apache.org/download.cgi
2. $tar xvf apache-maven-3.5.4-bin.tar.gz
3. copy the apache folder to desired place $cp -R apache-maven-3.5.4 /Users/locals
4. go to apache directory $cd /Users/locals/apache-maven-3.5.4/
5. create .bash_profile $vim ~/.bash_profile
6. write these two command : export M2_HOME=/Users/manisha/apache-maven-3.5.4 export PATH=$PATH:$M2_HOME/bin 7 save and quit the vim :wq!
7. restart the terminal and type mvn -version

simply pass your entire code as an argument of timeit:

import timeit

print(timeit.timeit(

"""   
limit = 10000
prime_list = [i for i in range(2, limit+1)]

for prime in prime_list:
    for elem in range(prime*2, max(prime_list)+1, prime):
        if elem in prime_list:
            prime_list.remove(elem)
"""   
, number=10))

For Laravel >= 5.2

Use the ->pluck() method

$roles = DB::table('roles')->pluck('title');

If you would like to retrieve an array containing the values of a single column, you may use the pluck method

For Laravel <= 5.1

Use the ->lists() method

$roles = DB::table('roles')->lists('title');

This method will return an array of role titles. You may also specify a custom key column for the returned array:

So you can just revert the file that you deleted but remember, If you are working on any type of project with a set project file (like iOS), reverting the file will add it to your system folder structure but not your project file structure. additional steps may be required if you are in this case
