C++ programs are translated to assembly programs during the generation of machine code from the source code. It would be virtually wrong to say assembly is slower than C++. Moreover, the binary code generated differs from compiler to compiler. So a smart C++ compiler may produce binary code more optimal and efficient than a dumb assembler's code.

However I believe your profiling methodology has certain flaws. The following are general guidelines for profiling:

1. Make sure your system is in its normal/idle state. Stop all running processes (applications) that you started or that use CPU intensively (or poll over the network).
2. Your datasize must be greater in size.
3. Your test must run for something more than 5-10 seconds.
4. Do not rely on just one sample. Perform your test N times. Collect results and calculate the mean or median of the result.

This is because your servlet is trying to access a request object which is no more exist.. A servlet's forward or include statement does not stop execution of method block. It continues to the end of method block or first return statement just like any other java method.

The best way to resolve this problem just set the page (where you suppose to forward the request) dynamically according your logic. That is:

protected void doPost(request , response){
String returnPage="default.jsp";
if(condition1){
 returnPage="page1.jsp";
}
if(condition2){
   returnPage="page2.jsp";
}
request.getRequestDispatcher(returnPage).forward(request,response); //at last line
}

and do the forward only once at last line...

you can also fix this problem using return statement after each forward() or put each forward() in if...else block

If you are at the root of your working directory, you can do git checkout -- . to check-out all files in the current HEAD and replace your local files.

You can also do git reset --hard to reset your working directory and replace all changes (including the index).

I had problems with collations as I had most of the tables with Modern_Spanish_CI_AS, but a few, which I had inherited or copied from another Database, had SQL_Latin1_General_CP1_CI_AS collation.

In my case, the easiest way to solve the problem has been as follows:

1. I've created a copy of the tables which were 'Latin American, using script table as...
2. The new tables have obviously acquired the 'Modern Spanish' collation of my database
3. I've copied the data of my 'Latin American' table into the new one, deleted the old one and renamed the new one.

I hope this helps other users.

You can use :

-XX:MaxPermSize=128m

to increase the space. But this usually only postpones the inevitable.

You can also enable the PermGen to be garbage collected

-XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Usually this occurs when doing lots of redeploys. I am surprised you have it using something like indexing. Use virtualvm or jconsole to monitor the Perm gen space and check it levels off after warming up the indexing.

Maybe you should consider changing to another JVM like the IBM JVM. It does not have a Permanent Generation and is immune to this issue.

You can use Visual Studio 2012.

Simply update your NuGet package in Visual Studio to Microsoft.AspNet.Mvc 5.0.

You may have to search pre-release.

Also the default project comes with Entity Framework 6.0, and ASP.NET Razor 3.0.

You may also need ASP.NET Identity Core and OWIN.

All of these can be downloaded/updated through menu Tools ? Library package manager ? Manage NuGet Packages for Solution....

If you don't yet have NuGet, follow this tutorial:

Using the bootstrap flex box helps us to control the placement and alignment of your navigation element. for the problem above adding mr-auto is a better solution to it .

<div id="app" class="container">
  <nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">Navbar</a>
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricingg</a>
      </li>
    </ul>
    <ul class="navbar-nav  " >
      <li  class="nav-item">
        <a class="nav-link" href="{{ url('/login') }}">Login</a>
      </li>
      <li  class="nav-item">
        <a class="nav-link" href="{{ url('/register') }}">Register</a>
      </li>
    </ul>
  </nav>
  @yield('content')
</div>

other placement may include

fixed- top
    fixed bottom
    sticky-top

It's possible to do this cleanly using a lambda in C++11 (tested in G++ 4.8.2).

Given this reusable typedef:

template<typename T>
using deleted_unique_ptr = std::unique_ptr<T,std::function<void(T*)>>;

You can write:

deleted_unique_ptr<Foo> foo(new Foo(), [](Foo* f) { customdeleter(f); });

For example, with a FILE*:

deleted_unique_ptr<FILE> file(
    fopen("file.txt", "r"),
    [](FILE* f) { fclose(f); });

With this you get the benefits of exception-safe cleanup using RAII, without needing try/catch noise.

Look at an HTML parser such as TagSoup, HTMLCleaner or NekoHTML.

There is a straightforward solution without messing with matplotlib: just pandas.

Tweaking the original example:

table = sql.read_frame(query,connection)

ax = table[0].plot(color=colors[0],ylim=(0,100))
ax2 = table[1].plot(secondary_y=True,color=colors[1], ax=ax)

ax.set_ylabel('Left axes label')
ax2.set_ylabel('Right axes label')

Basically, when the secondary_y=True option is given (eventhough ax=ax is passed too) pandas.plot returns a different axes which we use to set the labels.

I know this was answered long ago, but I think this approach worths it.

public ActionResult Download()
{
    var document = ...
    var cd = new System.Net.Mime.ContentDisposition
    {
        // for example foo.bak
        FileName = document.FileName, 

        // always prompt the user for downloading, set to true if you want 
        // the browser to try to show the file inline
        Inline = false, 
    };
    Response.AppendHeader("Content-Disposition", cd.ToString());
    return File(document.Data, document.ContentType);
}

NOTE: This example code above fails to properly account for international characters in the filename. See RFC6266 for the relevant standardization. I believe recent versions of ASP.Net MVC's File() method and the ContentDispositionHeaderValue class properly accounts for this. - Oskar 2016-02-25

ERRORLEVEL will contain the return code of the last command. Sadly you can only check >= for it.

Note specifically this line in the MSDN documentation for the If statement:

errorlevel Number

Specifies a true condition only if the previous program run by Cmd.exe returned an exit code equal to or greater than Number.

So to check for 0 you need to think outside the box:

IF ERRORLEVEL 1 GOTO errorHandling
REM no error here, errolevel == 0
:errorHandling

Or if you want to code error handling first:

IF NOT ERRORLEVEL 1 GOTO no_error
REM errorhandling, errorlevel >= 1
:no_error

Today I designed this Ant MacroDef for the same problem as yours :

Use it in your build file with :

    <!-- Compile a single JavaScript file in the bin dir for release -->
    <TypeScriptCompileDir
        src="${src-js.dir}"
        out="${release-file-path}"
        module="amd"
    />

It is used in the project PureMVC for TypeScript I'm working on at the time using Webstorm.

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

You'll need to get those bytes into a MemoryStream:

Bitmap bmp;
using (var ms = new MemoryStream(imageData))
{
    bmp = new Bitmap(ms);
}

That uses the Bitmap(Stream stream) constructor overload.

UPDATE: keep in mind that according to the documentation, and the source code I've been reading through, an ArgumentException will be thrown on these conditions:

stream does not contain image data or is null.
-or-
stream contains a PNG image file with a single dimension greater than 65,535 pixels.

Unfortunately, no. Not with HTML and CSS. You need an a element to make a link, and you can't wrap an entire table row in one.

The closest you can get is linking every table cell. Personally I'd just link one cell and use JavaScript to make the rest clickable. It's good to have at least one cell that really looks like a link, underlined and all, for clarity anyways.

Here's a simple jQuery snippet to make all table rows with links clickable (it looks for the first link and "clicks" it)

$("table").on("click", "tr", function(e) {
    if ($(e.target).is("a,input")) // anything else you don't want to trigger the click
        return;

    location.href = $(this).find("a").attr("href");
});

Sweet Persist is another one.

It is possible to serialize to and from streams in XML, JSON, Lua, and binary formats.

If what you want to see depends on the linking of the output, then objdump on the output object file/executable may also be useful in addition to the aforementioned gcc -S. Here's a very useful script by Loren Merritt that converts the default objdump syntax into the more readable nasm syntax:

#!/usr/bin/perl -w
$ptr='(BYTE|WORD|DWORD|QWORD|XMMWORD) PTR ';
$reg='(?:[er]?(?:[abcd]x|[sd]i|[sb]p)|[abcd][hl]|r1?[0-589][dwb]?|mm[0-7]|xmm1?[0-9])';
open FH, '-|', '/usr/bin/objdump', '-w', '-M', 'intel', @ARGV or die;
$prev = "";
while(<FH>){
    if(/$ptr/o) {
        s/$ptr(\[[^\[\]]+\],$reg)/$2/o or
        s/($reg,)$ptr(\[[^\[\]]+\])/$1$3/o or
        s/$ptr/lc $1/oe;
    }
    if($prev =~ /\t(repz )?ret / and
       $_ =~ /\tnop |\txchg *ax,ax$/) {
       # drop this line
    } else {
       print $prev;
       $prev = $_;
    }
}
print $prev;
close FH;

I suspect this can also be used on the output of gcc -S.

Its better to always encode spaces as %20, not as "+".

It was RFC-1866 (HTML 2.0 specification), which specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs. (see paragraph 8.2.1. subparagraph 1.). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.

Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses, according to RFC-1866. In other cases, spaces should be encoded to %20. But since it's hard to determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

Yeah there's no built in classes to do this that I'm aware of.

But that shouldn't really be an issue should it? It looks easy enough to parse just by storing the result of Stream.ReadToEnd() in a string, splitting based on new lines and then splitting each record on the = character. What you'd be left with is a bunch of key value pairs which you can easily toss into a dictionary.

Here's an example that might work for you:

public static Dictionary<string, string> GetProperties(string path)
{
    string fileData = "";
    using (StreamReader sr = new StreamReader(path))
    {
        fileData = sr.ReadToEnd().Replace("\r", "");
    }
    Dictionary<string, string> Properties = new Dictionary<string, string>();
    string[] kvp;
    string[] records = fileData.Split("\n".ToCharArray());
    foreach (string record in records)
    {
        kvp = record.Split("=".ToCharArray());
        Properties.Add(kvp[0], kvp[1]);
    }
    return Properties;
}

Here's an example of how to use it:

Dictionary<string,string> Properties = GetProperties("data.txt");
Console.WriteLine("Hello: " + Properties["Hello"]);
Console.ReadKey();

in the DBAdaper i.e Data Base helper class declare the table like this

 private static final String USERDETAILS=
    "create table userdetails(usersno integer primary key autoincrement,userid text not null ,username text not null,password text not null,photo BLOB,visibility text not null);";

insert the values like this,

first convert the images as byte[]

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
Bitmap bitmap = ((BitmapDrawable)getResources().getDrawable(R.drawable.common)).getBitmap();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);   
byte[] photo = baos.toByteArray(); 
db.insertUserDetails(value1,value2, value3, photo,value2);

in DEAdaper class

 public long insertUserDetails(String uname,String userid, String pass, byte[] photo,String visibility) 
{
    ContentValues initialValues = new ContentValues();
    initialValues.put("username", uname);
    initialValues.put("userid",userid);
    initialValues.put("password", pass);
    initialValues.put("photo",photo);
    initialValues.put("visibility",visibility);
    return db.insert("userdetails", null, initialValues);
}

retrieve the image as follows

Cursor cur=your query;
while(cur.moveToNext())
{
     byte[] photo=cur.getBlob(index of blob cloumn);
}

convert the byte[] into image

ByteArrayInputStream imageStream = new ByteArrayInputStream(photo);
Bitmap theImage= BitmapFactory.decodeStream(imageStream);

I think this content may solve your problem

Try this code:

$(document).ready(function(){
    $('#YourControlID').click(function(){
        if() { //your condition
            $.messager.show({  
                title:'My Title',  
                msg:'The message content',  
                showType:'fade',  
                style:{  
                    right:'',  
                    bottom:''  
                }  
            });  
        }
    });
});

Use:

$(document).ready(function() {
    // put all your jQuery goodness in here.
});

Check out this for more info: http://www.learningjquery.com/2006/09/introducing-document-ready

Note: This should work as long as the script import for your JQuery library is above this call.

Update:

If for some reason your code is not loading synchronously (which I have never run into, but apparently may be possible from the comment below should not happen), you could code it like the following.

function yourFunctionToRun(){
    //Your JQuery goodness here
}

function runYourFunctionWhenJQueryIsLoaded() {
    if (window.$){
        //possibly some other JQuery checks to make sure that everything is loaded here

        yourFunctionToRun();
    } else {
        setTimeout(runYourFunctionWhenJQueryIsLoaded, 50);
    }
}

runYourFunctionWhenJQueryIsLoaded();

A simple and clean solution by leveraging language's dynamic type checking:

function IsNumeric (string) {
   if(string === ' '.repeat(string.length)){
     return false
   }
   return string - 0 === string * 1
}

if you don't care about white-spaces you can remove that " if "

see test cases below

function IsNumeric (string) {_x000D_
   if(string === ' '.repeat(string.length)){_x000D_
      return false_x000D_
   }_x000D_
   return string - 0 === string * 1_x000D_
}_x000D_
_x000D_
_x000D_
console.log('-1' + ' ? ' + IsNumeric('-1'))    _x000D_
console.log('-1.5' + ' ? ' + IsNumeric('-1.5')) _x000D_
console.log('0' + ' ? ' + IsNumeric('0'))     _x000D_
console.log('0.42' + ' ? ' + IsNumeric('0.42'))   _x000D_
console.log('.42' + ' ? ' + IsNumeric('.42'))    _x000D_
console.log('99,999' + ' ? ' + IsNumeric('99,999'))_x000D_
console.log('0x89f' + ' ? ' + IsNumeric('0x89f'))  _x000D_
console.log('#abcdef' + ' ? ' + IsNumeric('#abcdef'))_x000D_
console.log('1.2.3' + ' ? ' + IsNumeric('1.2.3')) _x000D_
console.log('' + ' ? ' + IsNumeric(''))    _x000D_
console.log('33 ' + ' ? ' + IsNumeric('33 '))

For me this was an error with the ref and react:

const quoteElement = React.useRef() const somethingElse = quoteElement!.current?.offsetHeight ?? 0

This would throw the error, the fix, to give it a type:

// <div> reference type
const divRef = React.useRef<HTMLDivElement>(null);

// <button> reference type
const buttonRef = React.useRef<HTMLButtonElement>(null);

// <br /> reference type
const brRef = React.useRef<HTMLBRElement>(null);

// <a> reference type
const linkRef = React.useRef<HTMLLinkElement>(null);

No more errors, hopefully in some way this might help somebody else, or even me in the future :P

Adding current working solution for 'FLAG_FULLSCREEN' is deprecated

Add the following to your theme in themes.xml

<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>

Worked perfectly for me.

One way of doing that is by using trap DEBUG:

f() { bash -c "$BASH_COMMAND" >& /tmp/out.log; }
trap 'f' DEBUG

Now most recently executed command's stdout and stderr will be available in /tmp/out.log

Only downside is that it will execute a command twice: once to redirect output and error to /tmp/out.log and once normally. Probably there is some way to prevent this behavior as well.

To switch to C99 mode in CodeBlocks, follow the next steps:

Click Project/Build options, then in tab Compiler Settings choose subtab Other options, and place -std=c99 in the text area, and click Ok.

This will turn C99 mode on for your Compiler.

I hope this will help someone!

You never want to call thread.sleep() on the UI thread as it sounds like you have figured out. This freezes the UI and is always a bad thing to do. You can use a separate Thread and postDelayed

This SO answer shows how to do that as well as several other options

Handler

TimerTask

You can look at these and see which will work best for your particular situation

getPathInfo() gives the extra path information after the URI, used to access your Servlet, where as getRequestURI() gives the complete URI.

I would have thought they would be different, given a Servlet must be configured with its own URI pattern in the first place; I don't think I've ever served a Servlet from root (/).

For example if Servlet 'Foo' is mapped to URI '/foo' then I would have thought the URI:

/foo/path/to/resource

Would result in:

RequestURI = /foo/path/to/resource

and

PathInfo = /path/to/resource

Modernizr runs quickly on page load to detect features; it then creates a JavaScript object with the results, and adds classes to the html element

User agent selection

The Javascript:

var b = document.documentElement;
        b.setAttribute('data-useragent',  navigator.userAgent);
        b.setAttribute('data-platform', navigator.platform );
        b.className += ((!!('ontouchstart' in window) || !!('onmsgesturechange' in window))?' touch':'');

Adds (e.g) the below to the html element:

data-useragent='Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C)'
data-platform='Win32'

Allowing very targetted CSS selectors, e.g.:

html[data-useragent*='Chrome/13.0'] .nav{
    background:url(img/radial_grad.png) center bottom no-repeat;
}

Footnote

If possible, avoid browser targeting. Identify and fix any issue(s) you identify. Support progressive enhancement and graceful degradation. With that in mind, this is an 'ideal world' scenario not always obtainable in a production environment, as such- the above should help provide some good options.

There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.

However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.

Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]

UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact

The ':' is a delimiter for key value pairs basically. In your example it is a Javascript Object Literal notation.

In javascript, Objects are defined with the colon delimiting the identifier for the property, and its value so you can have the following:

return { 
    Property1 : 125,
    Property2 : "something",
    Method1 : function() { /* do nothing */ },
    array: [5, 3, 6, 7]
};

and then use it like:

var o =  { 
    property1 : 125,
    property2 : "something",
    method1 : function() { /* do nothing */ },
    array: [5, 3, 6, 7]
};

alert(o.property1); // Will display "125"

A subset of this is also known as JSON (Javascript Object Notation) which is useful in AJAX calls because it is compact and quick to parse in server-side languages and Javascript can easily de-serialize a JSON string into an object.

// The parenthesis '(' & ')' around the object are important here
var o = eval('(' + "{key: \"value\"}" + ')');

You can also put the key inside quotes if it contains some sort of special character or spaces, but I wouldn't recommend that because it just makes things harder to work with.

Keep in mind that JavaScript Object Literal Notation in the JavaScript language is different from the JSON standard for message passing. The main difference between the 2 is that functions and constructors are not part of the JSON standard, but are allowed in JS object literals.

Nothing from above worked for me. The problem for me was that I had wrong source in my Java Build Path for android-support-v7-appcompat. When you go to Project> Build Path> Configure Build Path>. Under the Source tab make sure you have android-support-v7-appcompat/gen , android-support-v7-appcompat/libs and android-support-v7-appcompat/src and nothing else. Click OK and it should work.

OpenSSL is quite difficult. It's easy to accidentally throw away all your security by not doing negotiation exactly right. (Heck, I've been personally bitten by a bug where curl wasn't reading the OpenSSL alerts exactly right, and couldn't talk to some sites.)

If you really want quick and simple, put stud in front of your program an call it a day. Having SSL in a different process won't slow you down: http://vincent.bernat.im/en/blog/2011-ssl-benchmark.html

Java - encrypt / decrypt user name and password from a configuration file

Code from above link

DESKeySpec keySpec = new DESKeySpec("Your secret Key phrase".getBytes("UTF8"));
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
SecretKey key = keyFactory.generateSecret(keySpec);
sun.misc.BASE64Encoder base64encoder = new BASE64Encoder();
sun.misc.BASE64Decoder base64decoder = new BASE64Decoder();
.........

// ENCODE plainTextPassword String
byte[] cleartext = plainTextPassword.getBytes("UTF8");      

Cipher cipher = Cipher.getInstance("DES"); // cipher is not thread safe
cipher.init(Cipher.ENCRYPT_MODE, key);
String encryptedPwd = base64encoder.encode(cipher.doFinal(cleartext));
// now you can store it 
......

// DECODE encryptedPwd String
byte[] encrypedPwdBytes = base64decoder.decodeBuffer(encryptedPwd);

Cipher cipher = Cipher.getInstance("DES");// cipher is not thread safe
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] plainTextPwdBytes = (cipher.doFinal(encrypedPwdBytes));

As while developing react native apps, we play with the terminal so much

so I added a script in the scripts in the package.json file

"menu": "adb shell input keyevent 82"

and I hit $ yarn menu

for the menu to appear on the emulator it will forward the keycode 82 to the emulator via ADB not the optimal way but I like it and felt to share it.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

To improve on Ryan's answer:

   + (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)size {
CGFloat oldWidth = image.size.width;
        CGFloat oldHeight = image.size.height;

//You may need to take some retina adjustments into consideration here
        CGFloat scaleFactor = (oldWidth > oldHeight) ? width / oldWidth : height / oldHeight;

return [UIImage imageWithCGImage:image.CGImage scale:scaleFactor orientation:UIImageOrientationUp];
    }

Infinity, NaN and subnormals

These are important caveats that no other answer has mentioned so far.

First read this introduction to IEEE 754 and subnormal numbers: What is a subnormal floating point number?

Then, for single precision floats (32-bit):

• IEEE 754 says that if the exponent is all ones (0xFF == 255), then it represents either NaN or Infinity.

  This is why the largest non-infinite number has exponent 0xFE == 254 and not 0xFF.

  Then with the bias, it becomes:

  254 - 127 == 127
  

• FLT_MIN is the smallest normal number. But there are smaller subnormal ones! Those take up the -127 exponent slot.

All asserts of the following program pass on Ubuntu 18.04 amd64:

#include <assert.h>
#include <float.h>
#include <inttypes.h>
#include <math.h>
#include <stdlib.h>
#include <stdio.h>

float float_from_bytes(
    uint32_t sign,
    uint32_t exponent,
    uint32_t fraction
) {
    uint32_t bytes;
    bytes = 0;
    bytes |= sign;
    bytes <<= 8;
    bytes |= exponent;
    bytes <<= 23;
    bytes |= fraction;
    return *(float*)&bytes;
}

int main(void) {
    /* All 1 exponent and non-0 fraction means NaN.
     * There are of course many possible representations,
     * and some have special semantics such as signalling vs not.
     */
    assert(isnan(float_from_bytes(0, 0xFF, 1)));
    assert(isnan(NAN));
    printf("nan                  = %e\n", NAN);

    /* All 1 exponent and 0 fraction means infinity. */
    assert(INFINITY == float_from_bytes(0, 0xFF, 0));
    assert(isinf(INFINITY));
    printf("infinity             = %e\n", INFINITY);

    /* ANSI C defines FLT_MAX as the largest non-infinite number. */
    assert(FLT_MAX == 0x1.FFFFFEp127f);
    /* Not 0xFF because that is infinite. */
    assert(FLT_MAX == float_from_bytes(0, 0xFE, 0x7FFFFF));
    assert(!isinf(FLT_MAX));
    assert(FLT_MAX < INFINITY);
    printf("largest non infinite = %e\n", FLT_MAX);

    /* ANSI C defines FLT_MIN as the smallest non-subnormal number. */
    assert(FLT_MIN == 0x1.0p-126f);
    assert(FLT_MIN == float_from_bytes(0, 1, 0));
    assert(isnormal(FLT_MIN));
    printf("smallest normal      = %e\n", FLT_MIN);

    /* The smallest non-zero subnormal number. */
    float smallest_subnormal = float_from_bytes(0, 0, 1);
    assert(smallest_subnormal == 0x0.000002p-126f);
    assert(0.0f < smallest_subnormal);
    assert(!isnormal(smallest_subnormal));
    printf("smallest subnormal   = %e\n", smallest_subnormal);

    return EXIT_SUCCESS;
}

Compile and run with:

gcc -ggdb3 -O0 -std=c11 -Wall -Wextra -Wpedantic -Werror -o subnormal.out subnormal.c
./subnormal.out

Output:

infinity             = inf
largest non infinite = 3.402823e+38
smallest normal      = 1.175494e-38
smallest subnormal   = 1.401298e-45

To update the local list of remote branches:

git remote update origin --prune

To show all local and remote branches that (local) Git knows about

git branch -a

x='buffalo'    
exec("%s = %d" % (x,2))

After that you can check it by:

print buffalo

As an output you will see: 2

using ILIKE instead of LIKE

SELECT id FROM groups WHERE name ILIKE 'Administrator'

Use strpos and substr:

<?php

$longString = "I have a code snippet written in PHP that pulls a block of text.";
$truncated = substr($longString,0,strpos($longString,' ',30));

echo $truncated;

This will give you a string truncated at the first space after 30 characters.

Do you have access to the SQL Server you are querying? Can you see a Table or View called dbo.Projects there? If not, that would be a good place to look.

Linq to SQL creates an object map between the database and the application. If your new DLL that you're deploying doesn't match with the database anymore, then this is the sort of error you'd expect to get.

Do you perhaps have different database schemas between your development environment and the deployment environment?

The emulator is much much faster when running on Linux. In Ubuntu 13.04, it launches within 10 seconds, and it runs nearly as smoothly as on a physical device. I haven't been able to reproduce the performance on Windows.

EDIT: Actually, after the first boot, when using the Atom arch. and GPU acceleration, the Windows emulator runs nearly as well as in Linux.

Today I ran into the same error, however, i was using Android Studio 1.0.2. What i did tot fix the problem was that i started a project with minimum SDK 4.4 (API 19) so when i checked the version i noticed that at File->ProjectStructure->app i found Android 5 as a compile SDK Version. I changed that back to 4.4.

quick answer

#include<stdio.h>   
#include<time.h>   

int main()   
{   
    clock_t t1, t2;  
    t1 = clock();   
    int i;
    for(i = 0; i < 1000000; i++)   
    {   
        int x = 90;  
    }   

    t2 = clock();   

    float diff = ((float)(t2 - t1) / 1000000.0F ) * 1000;   
    printf("%f",diff);   

    return 0;   
}

Here's one RegExp that does the trick.

'good_luck_buddy' . split(/^.*?_/)[1] 

First it forces the match to start from the start with the '^'. Then it matches any number of characters which are not '_', in other words all characters before the first '_'.

The '?' means a minimal number of chars that make the whole pattern match are matched by the '.*?' because it is followed by '_', which is then included in the match as its last character.

Therefore this split() uses such a matching part as its 'splitter' and removes it from the results. So it removes everything up till and including the first '_' and gives you the rest as the 2nd element of the result. The first element is "" representing the part before the matched part. It is "" because the match starts from the beginning.

There are other RegExps that work as well like /_(.*)/ given by Chandu in a previous answer.

The /^.*?_/ has the benefit that you can understand what it does without having to know about the special role capturing groups play with replace().

A connection timeout is the maximum amount of time that the program is willing to wait to setup a connection to another process. You aren't getting or posting any application data at this point, just establishing the connection, itself.

A socket timeout is the timeout when waiting for individual packets. It's a common misconception that a socket timeout is the timeout to receive the full response. So if you have a socket timeout of 1 second, and a response comprised of 3 IP packets, where each response packet takes 0.9 seconds to arrive, for a total response time of 2.7 seconds, then there will be no timeout.

Based on the answer by Eduard Florinescu, but with newer code and the missing imports added:

$ cat work-auth.py

chrome_options.add_argument("user-data-dir=chrome-data")
driver.get('https://www.somedomainthatrequireslogin.com')

for someone who comes across this and is trying to debug:

1) the django csrf check (assuming you're sending one) is here

2) In my case, settings.CSRF_HEADER_NAME was set to 'HTTP_X_CSRFTOKEN' and my AJAX call was sending a header named 'HTTP_X_CSRF_TOKEN' so stuff wasn't working. I could either change it in the AJAX call, or django setting.

3) If you opt to change it server-side, find your install location of django and throw a breakpoint in the csrf middleware.f you're using virtualenv, it'll be something like: ~/.envs/my-project/lib/python2.7/site-packages/django/middleware/csrf.py

import ipdb; ipdb.set_trace() # breakpoint!!
if request_csrf_token == "":
    # Fall back to X-CSRFToken, to make things easier for AJAX,
    # and possible for PUT/DELETE.
    request_csrf_token = request.META.get(settings.CSRF_HEADER_NAME, '')

Then, make sure the csrf token is correctly sourced from request.META

4) If you need to change your header, etc - change that variable in your settings file

Just type perfmon into Start > Run and press enter. When the Performance window is open, click on the + sign to add new counters to the graph. The counters are different aspects of how your PC works and are grouped by similarity into groups called "Performance Object".

For your questions, you can choose the "Process", "Memory" and "Processor" performance objects. You then can see these counters in real time

You can also specify the utility to save the performance data for your inspection later. To do this, select "Performance Logs and Alerts" in the left-hand panel. (It's right under the System Monitor console which provides us with the above mentioned counters. If it is not there, click "File" > "Add/remove snap-in", click Add and select "Performance Logs and Alerts" in the list".) From the "Performance Logs and Alerts", create a new monitoring configuration under "Counter Logs". Then you can add the counters, specify the sampling rate, the log format (binary or plain text) and log location.

To add it as a dependency do the following:

• Highlight the added project in your file explorer within xcode. In the directory browser window to the right it should show a file with a .a extension. There is a checkbox under the target column (target icon), check it.
• Right-Click on your Target (under the targets item in the file explorer) and choose Get Info
• On the general tab is a Direct Dependencies section. Hit the plus button
• Choose the project and click Add Target

here's an updated fiddle where the user's input is saved in local storage automatically. each time the fiddle is re-run or the page is refreshed the previous state is restored. this way you do not need to prompt users to save, it just saves on it's own.

Think of a 2D array as an array of arrays.

If you have data already present in both the tables and you want to update a table column values based on some condition then use this

UPDATE Table1 set Name=(select t2.Name from Table2 t2 where t2.id=Table1.id)

If you're prepared to use a little jQuery, the answer is simple!

$(function() {
    $('.parent').find('.child').css('height', $('.parent').innerHeight());
});

This works well for floating a single element to a side with 100% height of it's parent while other floated elements which would normally wrap around are kept to one side.

Hope this helps fellow jQuery fans.

I just wondered, why col-xs-6 did not work for me but then I found the answer in the Bootstrap 4 documentation. The class prefix for extra small devices is now col- while in the previous versions it was col-xs.

https://getbootstrap.com/docs/4.1/layout/grid/#grid-options

Bootstrap 4 dropped all col-xs-* classes, so use col-* instead. For example col-xs-6 replaced by col-6.

To escape %, you will need to double it up: %%.

Want to center an image? Very easy, Bootstrap comes with two classes, .center-block and text-center.

Use the former in the case of your image being a BLOCK element, for example, adding img-responsive class to your img makes the img a block element. You should know this if you know how to navigate in the web console and see applied styles to an element.

Don't want to use a class? No problem, here is the CSS bootstrap uses. You can make a custom class or write a CSS rule for the element to match the Bootstrap class.

 // In case you're dealing with a block element apply this to the element itself 
.center-block {
   margin-left:auto;
   margin-right:auto;
   display:block;
}

// In case you're dealing with a inline element apply this to the parent 
.text-center {
   text-align:center
}

$(document).ready(function() {
  $('td').on('click', function() {
    var value = $this.text();

Step by step self explaining commands for update of feature branch with the latest code from origin "develop" branch:

git checkout develop
git pull -p
git checkout feature_branch
git merge develop
git push origin feature_branch

1. https://pypi.python.org/pypi/openpyxl download zip file and unzip it on local system.
2. go to openpyxl folder where setup.py is present.
3. open command prompt under the same path.
4. Run a command: python setup.py install
5. It will install openpyxl.

Observations:

• #include <cstring> should introduce std::strcpy().
• using namespace std; (as written in medico.h) introduces any identifiers from std:: into the global namespace.

Aside from using namespace std; being somewhat clumsy once the application grows larger (as it introduces one hell of a lot of identifiers into the global namespace), and that you should never use using in a header file (see below!), using namespace does not affect identifiers introduced after the statement.

(using namespace std is written in the header, which is included in medico.cpp, but #include <cstring> comes after that.)

My advice: Put the using namespace std; (if you insist on using it at all) into medico.cpp, after any includes, and use explicit std:: in medico.h.

strcmpi() is not a standard function at all; while being defined on Windows, you have to solve case-insensitive compares differently on Linux.

(On general terms, I would like to point to this answer with regards to "proper" string handling in C and C++ that takes Unicode into account, as every application should. Summary: The standard cannot handle these things correctly; do use ICU.)

warning: deprecated conversion from string constant to ‘char*’

A "string constant" is when you write a string literal (e.g. "Hello") in your code. Its type is const char[], i.e. array of constant characters (as you cannot change the characters). You can assign an array to a pointer, but assigning to char *, i.e. removing the const qualifier, generates the warning you are seeing.

OT clarification: using in a header file changes visibility of identifiers for anyone including that header, which is usually not what the user of your header file wants. For example, I could use std::string and a self-written ::string just perfectly in my code, unless I include your medico.h, because then the two classes will clash.

Don't use using in header files.

And even in implementation files, it can introduce lots of ambiguity. There is a case to be made to use explicit namespacing in implementation files as well.

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

As mentioned, one way is to use

new Integer(my_int_value)

But you should not call the constructor for wrapper classes directly

So, modify the code accordingly:

mBitmapCache.put(Integer.valueOf(R.drawable.bg1),object);

If you need two variables in the XML, you can use:

%1$d text... %2$d or %1$s text... %2$s for string variables.

Example :

strings.xml

<string name="notyet">Website %1$s isn\'t yet available, I\'m working on it, please wait %2$s more days</string>

activity.java

String site = "site.tld";
String days = "11";

//Toast example
String notyet = getString(R.string.notyet, site, days);
Toast.makeText(getApplicationContext(), notyet, Toast.LENGTH_LONG).show();

After 48 hours of the still not being updated I removed the app from sale on Pricing and Availability.

Then I waited 1 hour.

Then I ticked All Territories Selected again.

After the app came available for download again the version number was updated.

Instead of using an Array, consider using either a Hash or a Set.

Sets behave similar to an Array, only they contain unique values only, and, under the covers, are built on Hashes. Sets don't retain the order that items are put into them unlike Arrays. Hashes don't retain the order either but can be accessed via a key so you don't have to traverse the hash to find a particular item.

I favor using Hashes. In your application the user_id could be the key and the value would be the entire object. That will automatically remove any duplicates from the hash.

Or, only extract unique values from the database, like John Ballinger suggested.

You can combine attribute selectors this way:

$("[attr1=val][attr2=val]")...

so that an element has to satisfy both conditions. Of course you can use this for more than two. Also, don't do [type=checkbox]. jQuery has a selector for that, namely :checkbox so the end result is:

$("input:checkbox[name=ProductCode]")...

Attribute selectors are slow however so the recommended approach is to use ID and class selectors where possible. You could change your markup to:

<input type="checkbox" class="ProductCode" name="ProductCode"value="396P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="401P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="F460129">

allowing you to use the much faster selector of:

$("input.ProductCode")...

If it was installed with plesk (not sure if it's just that, or on the phpmyadmin side: It changes the root user to admin.

You're going to have to do something like that i think (convert it into a more concrete type).

Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

List node process:

$ ps -e|grep node

Kill the process using

$kill -9 XXXX

Here XXXX is the process number

Difference between encodeURI and encodeURIComponent:

encodeURIComponent(value) is mainly used to encode queryString parameter values, and it encodes every applicable character in value. encodeURI ignores protocol prefix (http://) and domain name.

In very, very rare cases, when you want to implement manual encoding to encode additional characters (though they don't need to be encoded in typical cases) like: ! * , then you might use:

function fixedEncodeURIComponent(str) {
  return encodeURIComponent(str).replace(/[!*]/g, function(c) {
    return '%' + c.charCodeAt(0).toString(16);
  });
}

(source)

Actually, rebase saves your starting point to ORIG_HEAD so this is usually as simple as:

git reset --hard ORIG_HEAD

However, the reset, rebase and merge all save your original HEAD pointer into ORIG_HEAD so, if you've done any of those commands since the rebase you're trying to undo then you'll have to use the reflog.

I am assuming that you have used height attribute at both so i am comparing it with a height left do it with JavaScript.

var right=document.getElementById('rightdiv').style.height;
var left=document.getElementById('leftdiv').style.height;
if(left>right)
{
    document.getElementById('rightdiv').style.height=left;
}
else
{
    document.getElementById('leftdiv').style.height=right;
}

Another idea can be found here HTML/CSS: Making two floating divs the same height.

You need to write a controller with ng-change function in scope. In ng-change callback you do a call to server and update completions. Here is a stub (without $http as this is a plunk):

HTML

<!doctype html>
<html ng-app="plunker">
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
        <script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.4.0.js"></script>
        <script src="example.js"></script>
        <link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
    </head>
    <body>
        <div class='container-fluid' ng-controller="TypeaheadCtrl">
            <pre>Model: {{selected| json}}</pre>
            <pre>{{states}}</pre>
            <input type="text" ng-change="onedit()" ng-model="selected" typeahead="state for state in states | filter:$viewValue">
        </div>
    </body>
</html>

JS

angular.module('plunker', ['ui.bootstrap']);

function TypeaheadCtrl($scope) {
  $scope.selected = undefined;
  $scope.states = [];

  $scope.onedit = function(){
    $scope.states = [];

    for(var i = 0; i < Math.floor((Math.random()*10)+1); i++){
      var value = "";

      for(var j = 0; j < i; j++){
        value += j;
      }
      $scope.states.push(value);
    }
  }
}

After clicking on Properties of any installer(.exe) which block your application to install (Windows Defender SmartScreen prevented an unrecognized app ) for that issue i found one solution

1. Right click on installer(.exe)
2. Select properties option.
3. Click on checkbox to check Unblock at the bottom of Properties.

This solution work for Heroku CLI (heroku-x64) installer(.exe)

var month = mydate.getMonth(); // month (in integer 0-11)
var year = mydate.getFullYear(); // year

Then all you would need to have is an array of months:

var months = ['Jan', 'Feb', 'Mar', ...];

And then to show it:

alert(months[month] + "  " + year);

I would simply do the following to backup all new files from 7 days ago

tar --newer $(date -d'7 days ago' +"%d-%b") -zcf thisweek.tgz .

note you can also replace '7 days ago' with anything that suits your need

Can be : date -d'yesterday' +"%d-%b"

Or even : date -d'first Sunday last month' +"%d-%b"

console.log( String.fromCharCode(event.charCode) );

no need to map character i guess.

DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com

You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).

Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");

And you're done.

You can also specify a user and a password used to connect:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");

Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.

The directoryEntry.Path Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";

This would match the following AD hierarchy:

• com
  • example
    • Users
      • All Users
        • Specific Users

Simply write the hierarchy from deepest to highest.

Now you can do plenty of things

For example search a user by account name and get the user's surname:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
    PageSize = int.MaxValue,
    Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};

searcher.PropertiesToLoad.Add("sn");

var result = searcher.FindOne();

if (result == null) {
    return; // Or whatever you need to do in this case
}

string surname;

if (result.Properties.Contains("sn")) {
    surname = result.Properties["sn"][0].ToString();
}

ProcessStartInfo startInfo = new ProcessStartInfo(string.Concat(cPath, "\\", "HHTCtrlp.exe"));
startInfo.Arguments =cParams;
startInfo.UseShellExecute = false; 
System.Diagnostics.Process.Start(startInfo);

For this example you really should just use an outer join.

declare
begin
  FOR attr_rec IN ( 
    select attr 
    from USER_TABLE u 
    left outer join attribute_table a 
    on ( u.USERTYPE = 'X' and a.user_id = u.id ) 
  ) LOOP
    <process records> 
    <if primary key of attribute_table is null 
     then the attribute does not exist for this user.>
  END LOOP;
END;

Oracle SQL Developer > View > DBA > Select your connection > Expand > Security > Users > Right click your user > Create like > Fill in fields > Copy SQL script > Close

If your user has object privileges, do this also

Oracle SQL Developer > View > DBA > Select your connection > Expand > Security > Users > Double click your user > Object Privs > Select all data > Right click > Export > Export as text file

Edit that text file to grant object privileges to your user.

In your xampppath\apache\conf\extra open file httpd-xampp.conf and find the below tag:

# Close XAMPP sites here
<LocationMatch "^/(?i:(?:xampp|licenses|phpmyadmin|webalizer|server-status|server-info))">
    Order deny,allow
    Deny from all
    Allow from ::1 127.0.0.0/8 
    ErrorDocument 403 /error/HTTP_XAMPP_FORBIDDEN.html.var
</LocationMatch>

and add

"Allow from all"

after Allow from ::1 127.0.0.0/8 {line}

Restart xampp, and you are done.

In later versions of Xampp

...you can simply remove this part

#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
        Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</LocationMatch>

from the same file and it should work over the local network.

Swift 3:

If you want to go back to the previous view controller

_ = navigationController?.popViewController(animated: true)

If you want to go back to the root view controller

_ = navigationController?.popToRootViewController(animated: true)

You can set the tintColor property on the button (or bar button item) or the view controller's view. By default, the property will inherit the tint from the parent view, all the way up to the top level UIWindow of your app.

Check the available projects by running: gcloud projects list. This will give you a list of projects which you can access. To switch between projects: gcloud config set project <project-id>.

Also, I recommend checking the active config before making any change to gcloud config. You can do so by running: gcloud config list

You can use iReport editor to define the layout, and publish the report in jasper reports server. After publish you can invoke the rest api to get the results.

Here is the test of the functionality:

from django.test import TestCase
from x_reports_jasper.models import JasperServerClient

"""
    to try integraction with jasper server through rest
"""
class TestJasperServerClient(TestCase):

    # define required objects for tests
    def setUp(self):

        # load the connection to remote server
        try:

            self.j_url = "http://127.0.0.1:8080/jasperserver"
            self.j_user = "jasperadmin"
            self.j_pass = "jasperadmin"

            self.client = JasperServerClient.create_client(self.j_url,self.j_user,self.j_pass)

        except Exception, e:
            # if errors could not execute test given prerrequisites
            raise

    # test exception when server data is invalid
    def test_login_to_invalid_address_should_raise(self):
        self.assertRaises(Exception,JasperServerClient.create_client, "http://127.0.0.1:9090/jasperserver",self.j_user,self.j_pass)

    # test execute existent report in server
    def test_get_report(self):

        r_resource_path = "/reports/<PathToPublishedReport>"
        r_format = "pdf"
        r_params = {'PARAM_TO_REPORT':"1",}

        #resource_meta = client.load_resource_metadata( rep_resource_path )

        [uuid,out_mime,out_data] = self.client.generate_report(r_resource_path,r_format,r_params)
        self.assertIsNotNone(uuid)

The schema definition for an attribute determines whether an attribute must have a value. If the manager attribute in the example given is the attribute defined in RFC4524 with OID 0.9.2342.19200300.100.1.10, then that attribute has DN syntax. DN syntax is a sequence of relative distinguished names and must not be empty. The filter given in the example is used to cause the LDAP directory server to return only entries that do not have a manager attribute to the LDAP client in the search result.

You can use the fuser command, like:

fuser file_name

You will receive a list of processes using the file.

You can use different flags with it, in order to receive a more detailed output.

You can find more info in the fuser's Wikipedia article, or in the man pages.

Well, if exclusion of certain filename patterns had to be performed by every unix-ish file utility (like cp, mv, rm, tar, rsync, scp, ...), an immense duplication of effort would occur. Instead, such things can be done as part of globbing, i.e. by your shell.

bash

man 1 bash, / extglob.

Example:

So you just put a pattern inside !(), and it negates the match. The pattern can be arbitrarily complex, starting from enumeration of individual paths (as Vanwaril shows in another answer): !(filename1|path2|etc3), to regex-like things with stars and character classes. Refer to the manpage for details.

zsh

man 1 zshexpn, / filename generation.

You can do setopt KSH_GLOB and use bash-like patterns. Or,

% setopt EXTENDED_GLOB
% echo images/*
images/004.bmp images/033.jpg images/1276338351183.jpg images/2252.png
% echo images/*~*.jpg
images/004.bmp images/2252.png

So x~y matches pattern x, but excludes pattern y. Once again, for full details refer to manpage.

fish^new!

The fish shell has a much prettier answer to this:

 cp (string match -v '*.excluded.names' -- srcdir/*) destdir

Bonus pro-tip

Type cp *, hit CtrlX* and just see what happens. ^{it's not harmful I promise}

doing this shown above...

table tr{ float: left width: 100%; }  tr.classname { margin-bottom:5px; } 

removes vertical column alignment so be careful how you use it

My Python Solution:

def permutes(input,offset):
    if( len(input) == offset ):
        return [''.join(input)]

    result=[]        
    for i in range( offset, len(input) ):
         input[offset], input[i] = input[i], input[offset]
         result = result + permutes(input,offset+1)
         input[offset], input[i] = input[i], input[offset]
    return result

# input is a "string"
# return value is a list of strings
def permutations(input):
    return permutes( list(input), 0 )

# Main Program
print( permutations("wxyz") )

I don't know what "milliseconds and float seconds" means, but this should give you an idea:

#include <chrono>
#include <thread>
#include <iostream>

int main()
{
  auto then = std::chrono::system_clock::now();
  std::this_thread::sleep_for(std::chrono::seconds(1));
  auto now = std::chrono::system_clock::now();
  auto dur = now - then;
  typedef std::chrono::duration<float> float_seconds;
  auto secs = std::chrono::duration_cast<float_seconds>(dur);
  std::cout << secs.count() << '\n';
}

The technical part has been well-covered in the other answers, and it mainly ends in:
"He is wrong, he doesn't know stuff, ask him to join SO and get it all cleared :)"

I would like to address the fact(which has been mentioned in other answers) that this might be a stress-question and is an important tool for many interviewers to know more about you and how do you react to difficult and unusual situations. By giving you incorrect codes, he probably wanted to see if you argued back. To know whether you have the confidence to stand up against your seniors in situations similar to this.

P.S: I don't know why but I have a feeling that the interviewer has read this post.

Note that namespaces that are in the format of a valid Web URL don't necessarily need to be dereferenced i.e. you don't need to serve actual content at that URL. All that matters is that the namespace is globally unique.

This can also be done via CSS:pseudo-classes. Support isn't quite as wide and the answer above gives you the same result, but it's pure CSS-y =)

.ULHMenu li { border-left: solid 2px black; }
.ULHMenu li:first-child { border: 0px; }

OR:

.ULHMenu li { border-right: solid 2px black; }
.ULHMenu li:last-child { border: 0px; }

See: http://www.quirksmode.org/css/firstchild.html
Or: http://www.w3schools.com/cssref/sel_firstchild.asp

One line solution:

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

Or

Picasso.with(context).load("file:" + photoPath).into(imageView);

This will autodetect rotation and place image in correct orientation

Picasso is a very powerful library for handling images in your app includes: Complex image transformations with minimal memory use.

Troubleshooting

You have add this code:

 $mail->SMTPOptions = array(
        'ssl' => array(
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
        )
    );

And Enabling Allow less secure apps: "will usually solve the problem for PHPMailer, and it does not really make your app significantly less secure. Reportedly, changing this setting may take an hour or more to take effect, so don't expect an immediate fix"

This work for me!

ul>li selects all li that are a direct child of ul whereas ul li selects all li that are anywhere within (descending as deep as you like) a ul

For HTML:

<ul>
  <li><span><a href='#'>Something</a></span></li>
  <li><a href='#'>or Other</a></li>
</ul>

And CSS:

li a{ color: green; }
li>a{ color: red; }

The colour of Something will remain green but or Other will be red

Part 2, you should write the rule to be appropriate to the situation, I think the speed difference would be incredibly small, and probably overshadowed by the extra characters involved in writing more code, and definitely overshadowed by the time taken by the developer to think about it.

However, as a rule of thumb, the more specific you are with your rules, the faster the CSS engines can locate the DOM elements you want to apply it to, so I expect li>a is faster than li a as the DOM search can be cut short earlier. It also means that nested anchors are not styled with that rule, is that what you want? <~~ much more pertinent question.

this will work for everyone

<table border="your val" cellspacing="your val" cellpadding="your val" role="grid" style="width=100%; table-layout=fixed">_x000D_
<!-- set the table td element roll attr to gridcell -->_x000D_
<tr>_x000D_
<td roll="gridcell"></td>_x000D_
</tr>_x000D_
</table>

This will also work for table data created by iteration

Well, longs can't hold anything but integers.

One option is to use a float: float('234.89')

The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))

>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

Just you need to desc with asc. Write the query like below. It will return the values in ascending order.

SELECT * FROM table GROUP BY m_id ORDER BY m_id asc;

I found more accurate way to adding views like linear layouts in kotlin (Pass parent layout in inflate() and false)

val parentLayout = view.findViewById<LinearLayout>(R.id.llRecipientParent)
val childView = layoutInflater.inflate(R.layout.layout_recipient, parentLayout, false)
parentLayout.addView(childView)

Keep it simple:

 try:
     from . import mymodule     # "myapp" case
 except:
     import mymodule            # "__main__" case

Just to add to RichieHindle's answer, check out Floatutorial, which walks you through how CSS floating and clearing works.

This woked for me.

Hi All posting quite late hope it helps others, Thanking in advance to @GMK for this post Hibernate.initialize(object)

when Lazy="true"

Set<myObject> set=null;
hibernateSession.open
set=hibernateSession.getMyObjects();
hibernateSession.close();

now if i access 'set' after closing session it throws exception.

My solution :

Set<myObject> set=new HashSet<myObject>();
hibernateSession.open
set.addAll(hibernateSession.getMyObjects());
hibernateSession.close();

now i can access 'set' even after closing Hibernate Session.

Let me explain why sleep infinity works though it is not documented. jp48's answer is also useful.

The most important thing: By specifying inf or infinity (both case-insensitive), you can sleep for the longest time your implementation permits (i.e. the smaller value of HUGE_VAL and TYPE_MAXIMUM(time_t)).

Now let's dig into the details. The source code of sleep command can be read from coreutils/src/sleep.c. Essentially, the function does this:

double s; //seconds
xstrtod (argv[i], &p, &s, cl_strtod); //`p` is not essential (just used for error check).
xnanosleep (s);

Understanding xstrtod (argv[i], &p, &s, cl_strtod)

xstrtod()

According to gnulib/lib/xstrtod.c, the call of xstrtod() converts string argv[i] to a floating point value and stores it to *s, using a converting function cl_strtod().

cl_strtod()

As can be seen from coreutils/lib/cl-strtod.c, cl_strtod() converts a string to a floating point value, using strtod().

strtod()

According to man 3 strtod, strtod() converts a string to a value of type double. The manpage says

The expected form of the (initial portion of the) string is ... or (iii) an infinity, or ...

and an infinity is defined as

An infinity is either "INF" or "INFINITY", disregarding case.

Although the document tells

If the correct value would cause overflow, plus or minus HUGE_VAL (HUGE_VALF, HUGE_VALL) is returned

, it is not clear how an infinity is treated. So let's see the source code gnulib/lib/strtod.c. What we want to read is

else if (c_tolower (*s) == 'i'
         && c_tolower (s[1]) == 'n'
         && c_tolower (s[2]) == 'f')
  {
    s += 3;
    if (c_tolower (*s) == 'i'
        && c_tolower (s[1]) == 'n'
        && c_tolower (s[2]) == 'i'
        && c_tolower (s[3]) == 't'
        && c_tolower (s[4]) == 'y')
      s += 5;
    num = HUGE_VAL;
    errno = saved_errno;
  }

Thus, INF and INFINITY (both case-insensitive) are regarded as HUGE_VAL.

HUGE_VAL family

Let's use N1570 as the C standard. HUGE_VAL, HUGE_VALF and HUGE_VALL macros are defined in §7.12-3

The macro
    HUGE_VAL
expands to a positive double constant expression, not necessarily representable as a float. The macros
    HUGE_VALF
    HUGE_VALL
are respectively float and long double analogs of HUGE_VAL.

HUGE_VAL, HUGE_VALF, and HUGE_VALL can be positive infinities in an implementation that supports infinities.

and in §7.12.1-5

If a floating result overflows and default rounding is in effect, then the function returns the value of the macro HUGE_VAL, HUGE_VALF, or HUGE_VALL according to the return type

Understanding xnanosleep (s)

Now we understand all essence of xstrtod(). From the explanations above, it is crystal-clear that xnanosleep(s) we've seen first actually means xnanosleep(HUGE_VALL).

xnanosleep()

According to the source code gnulib/lib/xnanosleep.c, xnanosleep(s) essentially does this:

struct timespec ts_sleep = dtotimespec (s);
nanosleep (&ts_sleep, NULL);

dtotimespec()

This function converts an argument of type double to an object of type struct timespec. Since it is very simple, let me cite the source code gnulib/lib/dtotimespec.c. All of the comments are added by me.

struct timespec
dtotimespec (double sec)
{
  if (! (TYPE_MINIMUM (time_t) < sec)) //underflow case
    return make_timespec (TYPE_MINIMUM (time_t), 0);
  else if (! (sec < 1.0 + TYPE_MAXIMUM (time_t))) //overflow case
    return make_timespec (TYPE_MAXIMUM (time_t), TIMESPEC_HZ - 1);
  else //normal case (looks complex but does nothing technical)
    {
      time_t s = sec;
      double frac = TIMESPEC_HZ * (sec - s);
      long ns = frac;
      ns += ns < frac;
      s += ns / TIMESPEC_HZ;
      ns %= TIMESPEC_HZ;

      if (ns < 0)
        {
          s--;
          ns += TIMESPEC_HZ;
        }

      return make_timespec (s, ns);
    }
}

Since time_t is defined as an integral type (see §7.27.1-3), it is natural we assume the maximum value of type time_t is smaller than HUGE_VAL (of type double), which means we enter the overflow case. (Actually this assumption is not needed since, in all cases, the procedure is essentially the same.)

make_timespec()

The last wall we have to climb up is make_timespec(). Very fortunately, it is so simple that citing the source code gnulib/lib/timespec.h is enough.

_GL_TIMESPEC_INLINE struct timespec
make_timespec (time_t s, long int ns)
{
  struct timespec r;
  r.tv_sec = s;
  r.tv_nsec = ns;
  return r;
}

If you want to overwrite any css in bootstrap use !important

Let's say here is the page header class in bootstrap which have 40px margin on top, my client don't like it and he want it to be 15 on top and 10 on bottom only

.page-header {
    border-bottom: 1px solid #EEEEEE;
    margin: 40px 0 20px;
    padding-bottom: 9px;
}

So I added on class in my site.css file with the same name like this

.page-header
{
    padding-bottom: 9px;
    margin: 15px 0 10px 0px !important;
}

Note the !important with my margin, which will overwrite the margin of bootstarp page-header class margin.

Did you try using the UIButton from the Interface builder (that has rounded corners) and experimenting with the settings to make it look like a label. if all you want is to display static text within.

In my particular 'Hello World' case the cause for this problem was the fact, that my main() method was inside the Scala class.

I put the main() method under the Scala object and the error disappeared.

That is because Scala object in Java terms is the entity with only static members and methods inside.

That is why Java's public static void main() in Scala must be placed under object.

(Scala class may not contain static's inside)

You should use html height attribute for the canvas element as:

<div class="chart">
    <canvas id="myChart" height="100"></canvas>
</div>

Yet another solution that doesn't require changes in python code and so is better for designers and one-off presentational changes: django-widget-tweaks. Hope somebody will find it useful.

Common practice for handling currency is to use decimal type. Here is a simple example from "Agile Web Development with Rails"

add_column :products, :price, :decimal, :precision => 8, :scale => 2 

This will allow you to handle prices from -999,999.99 to 999,999.99
You may also want to include a validation in your items like

def validate 
  errors.add(:price, "should be at least 0.01") if price.nil? || price < 0.01 
end 

to sanity-check your values.

Here is a good resource: http://charliepark.org/bootstrap_buttons/

You can change color and see the effect in action.

You can use - matplotlib.gridspec.GridSpec

Check - https://matplotlib.org/stable/api/_as_gen/matplotlib.gridspec.GridSpec.html

The below code displays a heatmap on right and an Image on left.

#Creating 1 row and 2 columns grid
gs = gridspec.GridSpec(1, 2) 
fig = plt.figure(figsize=(25,3))

#Using the 1st row and 1st column for plotting heatmap
ax=plt.subplot(gs[0,0])
ax=sns.heatmap([[1,23,5,8,5]],annot=True)

#Using the 1st row and 2nd column to show the image
ax1=plt.subplot(gs[0,1])
ax1.grid(False)
ax1.set_yticklabels([])
ax1.set_xticklabels([])

#The below lines are used to display the image on ax1
image = io.imread("https://images-na.ssl-images- amazon.com/images/I/51MvhqY1qdL._SL160_.jpg")

plt.imshow(image)
plt.show()

Output image

Make sure that your <td> is not display: block;

Floating will do this, but much easier to just: display: inline;

flatMap transform the items emitted by an Observable into new Observables, then flattens the emissions from those into a single Observable.

Check out the scenario below where get("posts") returns an Observable that is "flattened" by flatMap.

myObservable.map(e => get("posts")).subscribe(o => console.log(o));
// this would log Observable objects to console.  

myObservable.flatMap(e => get("posts")).subscribe(o => console.log(o));
// this would log posts to console.

1. Make sure you have sbt and run sbt eclipse from the project root directory.
2. In eclipse, use File --> Import --> General --> Existing Projects into Workspace, selecting that same location, so that eclipse builds its project structure for the file structure having just been prepared by sbt.

I like Jon Skeet's answer, but would like to add one thing. I'm not sure if Jon was expecting the ctor to always be passed in the Local timezone. But I want to use it for cases where it's something other then local.

I'm reading values from a database, and I know what timezone that database is in. So in the ctor, I'll pass in the timezone of the database. But then I would like the value in local time. Jon's LocalTime does not return the original date converted into a local timezone date. It returns the date converted into the original timezone (whatever you had passed into the ctor).

I think these property names clear it up...

public DateTime TimeInOriginalZone { get { return TimeZoneInfo.ConvertTime(utcDateTime, timeZone); } }
public DateTime TimeInLocalZone    { get { return TimeZoneInfo.ConvertTime(utcDateTime, TimeZoneInfo.Local); } }
public DateTime TimeInSpecificZone(TimeZoneInfo tz)
{
    return TimeZoneInfo.ConvertTime(utcDateTime, tz);
}

The answer by Alex78191 has worked for me.

public File getTempFile(MultipartFile multipartFile)
{

CommonsMultipartFile commonsMultipartFile = (CommonsMultipartFile) multipartFile;
FileItem fileItem = commonsMultipartFile.getFileItem();
DiskFileItem diskFileItem = (DiskFileItem) fileItem;
String absPath = diskFileItem.getStoreLocation().getAbsolutePath();
File file = new File(absPath);

//trick to implicitly save on disk small files (<10240 bytes by default)

if (!file.exists()) {
    file.createNewFile();
    multipartFile.transferTo(file);
}

return file;
}

For uploading files having size greater than 10240 bytes please change the maxInMemorySize in multipartResolver to 1MB.

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- setting maximum upload size t 20MB -->
<property name="maxUploadSize" value="20971520" />
<!-- max size of file in memory (in bytes) -->
<property name="maxInMemorySize" value="1048576" />
<!-- 1MB --> </bean>

As You're getting values from textfield as jTextField3.getText();.

As it is a textField it will return you string format as its format says:

String getText()

      Returns the text contained in this TextComponent.

So, convert your String to Integer as:

int jml = Integer.parseInt(jTextField3.getText());

instead of directly setting

   int jml = jTextField3.getText();

Assignment in bash scripts cannot have spaces around the = and you probably want your date commands enclosed in backticks $():

#!/bin/bash
folder="ABC"
useracct='test'
day=$(date "+%d")
month=$(date "+%B")
year=$(date "+%Y")
folderToBeMoved="/users/$useracct/Documents/Archive/Primetime.eyetv"
newfoldername="/Volumes/Media/Network/$folder/$month$day$year"
ECHO "Network is $network" $network
ECHO "day is $day"
ECHO "Month is $month"
ECHO "YEAR is $year"
ECHO "source is $folderToBeMoved"
ECHO "dest is $newfoldername"
mkdir $newfoldername
cp -R $folderToBeMoved $newfoldername
if [-f $newfoldername/Primetime.eyetv]; then rm $folderToBeMoved; fi

With the last three lines commented out, for me this outputs:

Network is 
day is 16
Month is March
YEAR is 2010
source is /users/test/Documents/Archive/Primetime.eyetv
dest is /Volumes/Media/Network/ABC/March162010

I have to say your workflow is not in a standard Android way. In Android, you don't need to finish() your activity if you want to open another activity from Intent. As for user's convenience, Android allows user to use 'back' key to go back from the activity that you opened to your app.

So just let the system stop you activity and save anything need to when you activity is called back.

The other answers explain how to produce a string formatted like in your example, but if all you need to do is to print that stuff you could simply write:

first = 10
second = 20
print "First number is", first, "and second number is", second

I suggest this ugly method but it works:

length = 1
lenghtafterpadding = 3
newlength = '0' * (lenghtafterpadding - len(str(length))) + str(length)

I came here to find a lighter solution than this one!

We just need to use below query to dump one table data into other table.

Select * into SampleProductTracking_tableDump
from SampleProductTracking;

SampleProductTracking_tableDump is a new table which will be created automatically when using with above query. It will copy the records from SampleProductTracking to SampleProductTracking_tableDump

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

Change only in two line and you are getting actually what you want.

$query = $this->db->get();
$ret = $query->row();
return $ret->campaign_id;

try it.

If you just need the indexed columns EXEC sp_helpindex 'TABLE_NAME'

NPM shrinkwrap offers a nice solution to this problem. It allows us to override that version of a particular dependency of a particular sub-module.

Essentially, when you run npm install, npm will first look in your root directory to see whether a npm-shrinkwrap.json file exists. If it does, it will use this first to determine package dependencies, and then falling back to the normal process of working through the package.json files.

To create an npm-shrinkwrap.json, all you need to do is

 npm shrinkwrap --dev

code:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

You're using jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead you can use on method and bind the JavaScript load event:

 $(window).on('load', function () {
      alert("Window Loaded");
 });

Sometimes npm install -g webpack does not save properly. Better to use npm install webpack --save . It worked for me.

If you're using the South package to handle database migrations (highly recommended), then you could just use the ./manage.py migrate appname zero command.

Otherwise, I'd recommend the ./manage.py dbshell command, piping in SQL commands on standard input.

It would be neater to capture the error file thus:

ERROR=$(</tmp/Error)

The shell recognizes this and doesn't have to run 'cat' to get the data.

The bigger question is hard. I don't think there's an easy way to do it. You'd have to build the entire pipeline into the sub-shell, eventually sending its final standard output to a file, so that you can redirect the errors to standard output.

ERROR=$( { ./useless.sh | sed s/Output/Useless/ > outfile; } 2>&1 )

Note that the semi-colon is needed (in classic shells - Bourne, Korn - for sure; probably in Bash too). The '{}' does I/O redirection over the enclosed commands. As written, it would capture errors from sed too.

WARNING: Formally untested code - use at own risk.

As I did not find a proper way I wrote a script to do it and I'm sharing it here for those who need it. The script runs through all user tables and collects the columns. If the column type is any char type then it tries to convert it to the given collation.

Columns has to be index and constraint free for this to work.

If someone still has a better solution to this please post it!

When it comes to Google Analytics I found raik's answer at Secure Google tracking cookies very useful. It set secure and samesite to a value.

ga('create', 'UA-XXXXX-Y', {
    cookieFlags: 'max-age=7200;secure;samesite=none'
});

Use a Spannable String

 String s= "Hello Everyone";
 SpannableString ss1=  new SpannableString(s);
 ss1.setSpan(new RelativeSizeSpan(2f), 0,5, 0); // set size
 ss1.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);// set color
 TextView tv= (TextView) findViewById(R.id.textview);
 tv.setText(ss1); 

Snap shot

You can split string using space and add span to the string you require.

 String s= "Hello Everyone";  
 String[] each = s.split(" ");

Now apply span to the string and add the same to textview.

Rather than using jQuery or window.onload, native JavaScript has adopted some great functions since the release of jQuery. All modern browsers now have their own DOM ready function without the use of a jQuery library.

I'd recommend this if you use native Javascript.

document.addEventListener('DOMContentLoaded', function() {
    alert("Ready!");
}, false);

After the latest automatic Java update, I could not run Java from the command prompt.

My path variable had 'C:\ProgramData\Oracle\Java\javapath;'

I could not cd into 'C:\ProgramData\Oracle\Java\javapath;' from the command prompt window, since it did not exist.

I removed C:\ProgramData\Oracle\Java\javapath;' from the path variable and replaced it with 'C:\Program Files\Java\jre1.8.0_141\bin;'

Use a union when you have some function where you return a value that can be different depending on what the function did.

This problem is solved 100%. I was facing this problem , my project manager change the repo name but i was using old repo name.

Engineer@-Engi64 /g/xampp/htdocs/hospitality
$ git clone https://git-codecommit.us-east-2.amazonaws.com/v1/repo/cms
Cloning into 'cms'...

error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054
fatal: the remote end hung up unexpectedly

How i solved this problem. Repo link was not valid so that's why i am facing this issue. Please check your repo link before cloning.

Use the Alter table statement.

Alter table TableName Alter Column ColumnName nvarchar(100)

Shortest solution to be assign the window to a typescript variable then call the print method on that, like below

in template file

<button ... (click)="window.print()" ...>Submit</button>

and, in typescript file

window: any;
constructor() {
  this.window = window;
}

If you want to grab the query parameter value in the URL, follow below code pieces

//url.localhost:8888/p?tagid=1234
req.query.tagid
OR
req.param.tagid

If you want to grab the URL parameter using Express param function

Express param function to grab a specific parameter. This is considered middleware and will run before the route is called.

This can be used for validations or grabbing important information about item.

An example for this would be:

// parameter middleware that will run before the next routes
app.param('tagid', function(req, res, next, tagid) {

// check if the tagid exists
// do some validations
// add something to the tagid
var modified = tagid+ '123';

// save name to the request
req.tagid= modified;

next();
});

// http://localhost:8080/api/tags/98
app.get('/api/tags/:tagid', function(req, res) {
// the tagid was found and is available in req.tagid
res.send('New tag id ' + req.tagid+ '!');
});

highlight search

:set hlsearch 

in .vimrc that is

and search for space tabs and carriage returns

/ \|\t\|\r

or search for all whitespace characters

/\s

of search for all non white space characters (the whitespace characters are not shown, so you see the whitespace characters between words, but not the trailing whitespace characters)

/\S

to show all trailing white space characters - at the end of the line

/\s$

You can use parseInt with try and catch block

try
{
    int myVal= Integer.parseInt(mTextView.getText().toString());
}
catch (NumberFormatException e)
{
    // handle the exception
    int myVal=0;
}

Or you can create your own tryParse method :

public Integer tryParse(Object obj) {
    Integer retVal;
    try {
        retVal = Integer.parseInt((String) obj);
    } catch (NumberFormatException nfe) {
        retVal = 0; // or null if that is your preference
    }
    return retVal;
}

and use it in your code like:

int myVal= tryParse(mTextView.getText().toString());

Note: The following code without try/catch will throw an exception

int myVal= new Integer(mTextView.getText().toString()).intValue();

Or

int myVal= Integer.decode(mTextView.getText().toString()).intValue();

Bootstrap modal show event

$('#modal-content').on('show.bs.modal', function() {
$("#txtname").focus();

})

Rebuilding using the command line has fixed this issue for me multiple times. For example, running ant build (for an Ant project) or mvn build (for a Maven project) will fix eclipse once it succeeds.

I would follow this guide: https://github.com/bmoeskau/Extensible/blob/master/recurrence-overview.md

Also make sure you use the iCal format so not to reinvent the wheel and remember Rule #0: Do NOT store individual recurring event instances as rows in your database!

After trying everything and still failing this was my solution: i remembered i had and error last updating the MVC version in my Visual studio so i run the project from another Visual studio (different computer) and than uploaded the dll-s and it worked. maybe it will help someone...

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

Go ahead and add [STAThread] to the main entry of your application, this indicates the COM threading model is single-threaded apartment (STA)

example:

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new WebBrowser());
    }
}

Very simple just use this code, it will preserve the HTML, while removing unwrapped text only:

jQuery(function($){

    // Replace 'td' with your html tag
    $("td").html(function() { 

    // Replace 'ok' with string you want to change, you can delete 'hello everyone' to remove the text
          return $(this).html().replace("ok", "hello everyone");  

    });
});

Here is full example: https://blog.hfarazm.com/remove-unwrapped-text-jquery/

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

In my case, none of the solutions mentioned in other answer worked. I found out that the problem was specific to one repository. Deleting and cloning the repo again solved the issue.

The solution from this thread is to use the jquery plugin dotdotdot. Not a CSS solution, but it gives you a lot of options for "read more" links, dynamic resizing etc.

if(map.get(key) != null || (map.get(key) == null && map.containsKey(key)))

"Attach debugger to Android process" icon shoud be used in case when you set custom "android:process" in your Manifest file.
In my case I should select suitable process and click OK button just after "Wait for debugger" dialog appears.

If you are using Gradle,

def gitHash = new ByteArrayOutputStream()
    project.exec {
        commandLine 'git', 'rev-parse', '--short', 'HEAD'
        standardOutput = gitHash
    }

def gitBranch = new ByteArrayOutputStream()
    project.exec {
        def gitCmd = "git symbolic-ref --short -q HEAD || git branch -rq --contains "+getGitHash()+" | sed -e '2,\$d'  -e 's/\\(.*\\)\\/\\(.*\\)\$/\\2/' || echo 'master'"
        commandLine "bash", "-c", "${gitCmd}"
        standardOutput = gitBranch
    }

Why your code does not work?

The where method returns an ActiveRecord::Relation object (acts like an array which contains the results of the where), it can be empty but it will never be nil.

Business.where(id: -1) 
 #=> returns an empty ActiveRecord::Relation ( similar to an array )
Business.where(id: -1).nil? # ( similar to == nil? )
 #=> returns false
Business.where(id: -1).empty? # test if the array is empty ( similar to .blank? )
 #=> returns true

How to test if at least one record exists?

Option 1: Using .exists?

if Business.exists?(user_id: current_user.id)
  # same as Business.where(user_id: current_user.id).exists?
  # ...
else
  # ...
end

Option 2: Using .present? (or .blank?, the opposite of .present?)

if Business.where(:user_id => current_user.id).present?
  # less efficiant than using .exists? (see generated SQL for .exists? vs .present?)
else
  # ...
end

Option 3: Variable assignment in the if statement

if business = Business.where(:user_id => current_user.id).first
  business.do_some_stuff
else
  # do something else
end

This option can be considered a code smell by some linters (Rubocop for example).

Option 3b: Variable assignment

business = Business.where(user_id: current_user.id).first
if business
  # ...
else
  # ...
end

You can also use .find_by_user_id(current_user.id) instead of .where(...).first

Best option:

• If you don't use the Business object(s): Option 1
• If you need to use the Business object(s): Option 3

You either need to keep creating new objects, or clone the existing one. See What is the most efficient way to deep clone an object in JavaScript? for how to clone.

^\d{1,2}[\W_]?po$

\d defines a number and {1,2} means 1 or two of the expression before, \W defines a non word character.

I tend to just load the entire buffer as a raw memory chunk into memory and do the parsing on my own. That way I have best control over what the standard lib does on multiple platforms.

This is a stub I use for this. you may also want to check the error-codes for fseek, ftell and fread. (omitted for clarity).

char * buffer = 0;
long length;
FILE * f = fopen (filename, "rb");

if (f)
{
  fseek (f, 0, SEEK_END);
  length = ftell (f);
  fseek (f, 0, SEEK_SET);
  buffer = malloc (length);
  if (buffer)
  {
    fread (buffer, 1, length, f);
  }
  fclose (f);
}

if (buffer)
{
  // start to process your data / extract strings here...
}

I'm running Laravel 6 with Homestead and also ran into this problem. As suggested here in the other answers you can prefix COMPOSER_MEMORY_LIMIT=-1 to a single command and run the command normally. If you'd like to update your PHP config to always allow unlimited memory follow these steps.

vagrant up
vagrant ssh
php --version # 7.4
php --ini # Shows path to the php.ini file that's loaded
cd /etc/php/7.4/cli # your PHP version. Each PHP version has a folder
sudo vi php.ini

Add memory_limit=-1 to your php.ini file. If you're having trouble using Vim or making edits to the php.ini file check this answer about how to edit the php.ini file with Vim. The file should look something like this:

; Maximum amount of memory a script may consume
; http://php.net/memory-limit
memory_limit = -1

Note that this could eat up infinite amount of memory on your machine. Probably not a good idea for production lol. With Laravel Valet had to follow this article and update the memory value here:

sudo vi /usr/local/etc/php/7.4/conf.d/php-memory-limits.ini

Then restart the server with Valet:

valet restart

This answer was also helpful for changing the config with Laravel Valet on Mac so the changes take effect.

a complete circle in radians is 2*pi. A complete circle in degrees is 360. To go from degrees to radians, it's (d/360) * 2*pi, or d*pi/180.

ARIA stands for Accessible Rich Internet Applications.

WAI-ARIA is an incredibly powerful technology that allows developers to easily describe the purpose, state and other functionality of visually rich user interfaces - in a way that can be understood by Assistive Technology. WAI-ARIA has finally been integrated into the current working draft of the HTML 5 specification.

And if you are wondering what WAI-ARIA is, its the same thing.

Please note the terms WAI-ARIA and ARIA refer to the same thing. However, it is more correct to use WAI-ARIA to acknowledge its origins in WAI.

WAI = Web Accessibility Initiative

From the looks of it, ARIA is used for assistive technologies and mostly screen reading.

Most of your doubts will be cleared if you read this article

The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:

pip install xlrd==1.2.0

I resolved it using this code to WebApiConfig.cs file

var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects; 
config.Formatters.Remove(config.Formatters.XmlFormatter);

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   public class Main {
       @Test
       public void test(){
           System.out.println(System.getProperty("label"));
           assertEquals("label_value", System.getProperty("label"));
       }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value
   

Right click your project folder, look for Properties in Java build path and select the jar files that you see. It has worked for me.

In my case, my Android Studio version was 3.6.1 and i have modified the classpath like below;

_{I have been doing some extensive research into this and other REST paging related questions lately and thought it constructive to add some of my findings here. I'm expanding the question a bit to include thoughts on paging as well as the count as they are intimitely related.}

Headers

The paging metadata is included in the response in the form of response headers. The big benefit of this approach is that the response payload itself is just the actual data requestor was asking for. Making processing the response easier for clients that are not interested in the paging information.

There are a bunch of (standard and custom) headers used in the wild to return paging related information, including the total count.

X-Total-Count

X-Total-Count: 234

This is used in some APIs I found in the wild. There are also NPM packages for adding support for this header to e.g. Loopback. Some articles recommend setting this header as well.

It is often used in combination with the Link header, which is a pretty good solution for paging, but lacks the total count information.

Link

Link: </TheBook/chapter2>;
      rel="previous"; title*=UTF-8'de'letztes%20Kapitel,
      </TheBook/chapter4>;
      rel="next"; title*=UTF-8'de'n%c3%a4chstes%20Kapitel

I feel, from reading a lot on this subject, that the general consensus is to use the Link header to provide paging links to clients using rel=next, rel=previous etc. The problem with this is that it lacks the information of how many total records there are, which is why many APIs combine this with the X-Total-Count header.

Alternatively, some APIs and e.g. the JsonApi standard, use the Link format, but add the information in a response envelope instead of to a header. This simplifies access to the metadata (and creates a place to add the total count information) at the expense of increasing complexity of accessing the actual data itself (by adding an envelope).

Content-Range

Content-Range: items 0-49/234

Promoted by a blog article named Range header, I choose you (for pagination)!. The author makes a strong case for using the Range and Content-Range headers for pagination. When we carefully read the RFC on these headers, we find that extending their meaning beyond ranges of bytes was actually anticipated by the RFC and is explicitly permitted. When used in the context of items instead of bytes, the Range header actually gives us a way to both request a certain range of items and indicate what range of the total result the response items relate to. This header also gives a great way to show the total count. And it is a true standard that mostly maps one-to-one to paging. It is also used in the wild.

Envelope

Many APIs, including the one from our favorite Q&A website use an envelope, a wrapper around the data that is used to add meta information about the data. Also, OData and JsonApi standards both use a response envelope.

The big downside to this (imho) is that processing the response data becomes more complex as the actual data has to be found somewhere in the envelope. Also there are many different formats for that envelope and you have to use the right one. It is telling that the response envelopes from OData and JsonApi are wildly different, with OData mixing in metadata at multiple points in the response.

Separate endpoint

I think this has been covered enough in the other answers. I did not investigate this much because I agree with the comments that this is confusing as you now have multiple types of endpoints. I think it's nicest if every endpoint represents a (collection of) resource(s).

Further thoughts

We don't only have to communicate the paging meta information related to the response, but also allow the client to request specific pages/ranges. It is interesting to also look at this aspect to end up with a coherent solution. Here too we can use headers (the Range header seems very suitable), or other mechanisms such as query parameters. Some people advocate treating pages of results as separate resources, which may make sense in some use cases (e.g. /books/231/pages/52. I ended up selecting a wild range of frequently used request parameters such as pagesize, page[size] and limit etc in addition to supporting the Range header (and as request parameter as well).

I'm the developer of Redux Auth and some of the issues you mentioned have been fixed in the version 2 beta. You can download this off the offcial website with a sample application too.

• Requires autoloading (impeding performance)
• Uses the inherently unsafe concept of 'security questions'. Dealbreaker!

Security questions are now not used and a simpler forgotten password system has been put in place.

• Return types are a bit of a hodgepodge of true, false, error and success codes

This was fixed in version 2 and returns boolean values. I hated the hodgepodge as much as you.

• Doesn't hook into CI's validation system

The sample application uses the CI's validation system.

• Doesn't allow a user to resend a 'lost password' code

Work in progress

I also implemented some other features such as email views, this gives you the choice of being able to use the CodeIgniter helpers in your emails.

It's still a work in progress so if have any more suggestions please keep them coming.

Ps : Thanks for recommending Redux.

$mylabel.text( $mylabel.text().replace('-', '') );

Since text() gets the value, and text( "someValue" ) sets the value, you just place one inside the other.

Would be the equivalent of doing:

var newValue = $mylabel.text().replace('-', '');
$mylabel.text( newValue );

EDIT:

I hope I understood the question correctly. I'm assuming $mylabel is referencing a DOM element in a jQuery object, and the string is in the content of the element.

If the string is in some other variable not part of the DOM, then you would likely want to call the .replace() function against that variable before you insert it into the DOM.

Like this:

var someVariable = "-123456";
$mylabel.text( someVariable.replace('-', '') );

or a more verbose version:

var someVariable = "-123456";
someVariable = someVariable.replace('-', '');
$mylabel.text( someVariable );

Mongodb and Mongoose are two completely different things!

Mongodb is the database itself, while Mongoose is an object modeling tool for Mongodb

EDIT: As pointed out MongoDB is the npm package, thanks!

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

There are three different font families that I know of that you can choose from and each has its own weight element that needs to be applied:

First

font-family: 'Font Awesome 5 Brands'; content: "\f373";

Second

font-family: 'Font Awesome 5 Free'; content: "\f061"; font-weight: 900;

Third

font-family: 'Font Awesome 5 Pro';

Reference here - https://fontawesome.com/how-to-use/on-the-web/advanced/css-pseudo-elements

Hope this helps.

If you prefer ByteBuffer like @kalefranz, there is always the posibility to concatenate two byte[] (or even more) in one line, like this:

byte[] c = ByteBuffer.allocate(a.length+b.length).put(a).put(b).array();

select CONVERT(NVARCHAR, SYSDATETIME(), 106) AS [DD-MON-YYYY]

or else

select REPLACE(CONVERT(NVARCHAR,GETDATE(), 106), ' ', '-')

both works fine

(Ctrl+H) -> Find and Replace window opens -> Find what "0" ,Replace with " "(leave it blank )-> click options tick match entire cell contents -> click "Replace All" button .

If you're using vue-cli 3.x, you can simply pass the port to the npm command like so:

npm run serve -- --port 3000

Then visit http://localhost:3000/

UPDATE: matplotlib.mlab.PCA is since release 2.2 (2018-03-06) indeed deprecated.

The library matplotlib.mlab.PCA (used in this answer) is not deprecated. So for all the folks arriving here via Google, I'll post a complete working example tested with Python 2.7.

Use the following code with care as it uses a now deprecated library!

from matplotlib.mlab import PCA
import numpy
data = numpy.array( [[3,2,5], [-2,1,6], [-1,0,4], [4,3,4], [10,-5,-6]] )
pca = PCA(data)

Now in `pca.Y' is the original data matrix in terms of the principal components basis vectors. More details about the PCA object can be found here.

>>> pca.Y
array([[ 0.67629162, -0.49384752,  0.14489202],
   [ 1.26314784,  0.60164795,  0.02858026],
   [ 0.64937611,  0.69057287, -0.06833576],
   [ 0.60697227, -0.90088738, -0.11194732],
   [-3.19578784,  0.10251408,  0.00681079]])

You can use matplotlib.pyplot to draw this data, just to convince yourself that the PCA yields "good" results. The names list is just used to annotate our five vectors.

import matplotlib.pyplot
names = [ "A", "B", "C", "D", "E" ]
matplotlib.pyplot.scatter(pca.Y[:,0], pca.Y[:,1])
for label, x, y in zip(names, pca.Y[:,0], pca.Y[:,1]):
    matplotlib.pyplot.annotate( label, xy=(x, y), xytext=(-2, 2), textcoords='offset points', ha='right', va='bottom' )
matplotlib.pyplot.show()

Looking at our original vectors we'll see that data[0] ("A") and data[3] ("D") are rather similar as are data[1] ("B") and data[2] ("C"). This is reflected in the 2D plot of our PCA transformed data.

Do not use the command prompt in the IDE. Run the command prompt from windows as an administrator. I'm sure this will solve the problem. If not, uninstall pip and reinstall the latest one directly.

 <! ––  add this code in your class called menu_links -->
<style> 
.menu_links{
cursor: pointer;
}
</style>

In the above code [cursor:pointer] is used to access the hand like cursor that appears when you hover over a link.

And if you use [cursor: default] it will show the usual arrow cursor that appears.

You need to use custom comparator which will use compareToIgnoreCase, not compareTo.

It's been a while since I read it (so, I'm not sure how much of it is still relevant), but my recollection is that Joe Celko's SQL for Smarties book provides a lot of info on writing elegant, effective, and efficient queries.

You should set height of html, body, .wrapper to 100% (in order to inherit full height) and then just set a flex value greater than 1 to .row3 and not on the others.

.wrapper, html, body {
    height: 100%;
    margin: 0;
}
.wrapper {
    display: flex;
    flex-direction: column;
}
#row1 {
    background-color: red;
}
#row2 {
    background-color: blue;
}
#row3 {
    background-color: green;
    flex:2;
    display: flex;
}
#col1 {
    background-color: yellow;
    flex: 0 0 240px;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col2 {
    background-color: orange;
    flex: 1 1;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col3 {
    background-color: purple;
    flex: 0 0 240px;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}

<div class="wrapper">
    <div id="row1">this is the header</div>
    <div id="row2">this is the second line</div>
    <div id="row3">
        <div id="col1">col1</div>
        <div id="col2">col2</div>
        <div id="col3">col3</div>
    </div>
</div>
