From New-style and classic classes:

Up to Python 2.1, old-style classes were the only flavour available to the user.

The concept of (old-style) class is unrelated to the concept of type: if x is an instance of an old-style class, then x.__class__ designates the class of x, but type(x) is always <type 'instance'>.

This reflects the fact that all old-style instances, independently of their class, are implemented with a single built-in type, called instance.

New-style classes were introduced in Python 2.2 to unify the concepts of class and type. A new-style class is simply a user-defined type, no more, no less.

If x is an instance of a new-style class, then type(x) is typically the same as x.__class__ (although this is not guaranteed – a new-style class instance is permitted to override the value returned for x.__class__).

The major motivation for introducing new-style classes is to provide a unified object model with a full meta-model.

It also has a number of immediate benefits, like the ability to subclass most built-in types, or the introduction of "descriptors", which enable computed properties.

For compatibility reasons, classes are still old-style by default.

New-style classes are created by specifying another new-style class (i.e. a type) as a parent class, or the "top-level type" object if no other parent is needed.

The behaviour of new-style classes differs from that of old-style classes in a number of important details in addition to what type returns.

Some of these changes are fundamental to the new object model, like the way special methods are invoked. Others are "fixes" that could not be implemented before for compatibility concerns, like the method resolution order in case of multiple inheritance.

Python 3 only has new-style classes.

No matter if you subclass from object or not, classes are new-style in Python 3.

Use a CipherOutputStream or CipherInputStream with a Cipher and your FileInputStream / FileOutputStream.

I would suggest something like Cipher.getInstance("AES/CBC/PKCS5Padding") for creating the Cipher class. CBC mode is secure and does not have the vulnerabilities of ECB mode for non-random plaintexts. It should be present in any generic cryptographic library, ensuring high compatibility.

Don't forget to use a Initialization Vector (IV) generated by a secure random generator if you want to encrypt multiple files with the same key. You can prefix the plain IV at the start of the ciphertext. It is always exactly one block (16 bytes) in size.

If you want to use a password, please make sure you do use a good key derivation mechanism (look up password based encryption or password based key derivation). PBKDF2 is the most commonly used Password Based Key Derivation scheme and it is present in most Java runtimes, including Android. Note that SHA-1 is a bit outdated hash function, but it should be fine in PBKDF2, and does currently present the most compatible option.

Always specify the character encoding when encoding/decoding strings, or you'll be in trouble when the platform encoding differs from the previous one. In other words, don't use String.getBytes() but use String.getBytes(StandardCharsets.UTF_8).

To make it more secure, please add cryptographic integrity and authenticity by adding a secure checksum (MAC or HMAC) over the ciphertext and IV, preferably using a different key. Without an authentication tag the ciphertext may be changed in such a way that the change cannot be detected.

Be warned that CipherInputStream may not report BadPaddingException, this includes BadPaddingException generated for authenticated ciphers such as GCM. This would make the streams incompatible and insecure for these kind of authenticated ciphers.

Try:

(b-a).days

I tried with b and a of type datetime.date.

The comment in your code is wrong. INADDR_ANY doesn't put server's IP automatically'. It essentially puts 0.0.0.0, for the reasons explained in mark4o's answer.

Since android doesnt support <ol>, <ul> or <li> html elements, I had to do it like this

<string name="names"><![CDATA[<p><h2>List of Names:</h2></p><p>&#8226;name1<br />&#8226;name2<br /></p>]]></string>

if you want to maintain custom space then use </pre> tag

In jQuery 1.2 and newer you no longer have to position the element absolutely; you can use normal relative positioning and use += or -= to add to or subtract from properties, e.g.

$("#startAnimation").click(function(){
    $(".toBeAnimated").animate({ 
        marginLeft: "+=250px",
    }, 1000 );
});

And to echo the guy who answered first's advice: Javascript is not performant. Don't overuse animations, or expect things than run nice and fast on your high performance PC on Chrome to look good on a bog-standard PC running IE. Test it, and make sure it degrades well!

Probaly you can use Iframe for this. Facebook probably uses this technique. You can read more on this here. Stackoverflow uses similar technique, but with HTML5 local storage, more on this on their blog

Be aware that when you do press your <leader> key you have only 1000ms (by default) to enter the command following it.

This is exacerbated because there is no visual feedback (by default) that you have pressed your <leader> key and vim is awaiting the command; and so there is also no visual way to know when this time out has happened.

If you add set showcmd to your vimrc then you will see your <leader> key appear in the bottom right hand corner of vim (to the left of the cursor location) and perhaps more importantly you will see it disappear when the time out happens.

The length of the timeout can also be set in your vimrc, see :help timeoutlen for more information.

If your modulus / divisor is a known constant, and you care about performance, see this and this. A multiplicative inverse is even possible for loop-invariant values that aren't known until runtime, e.g. see https://libdivide.com/ (But without JIT code-gen, that's less efficient than hard-coding just the steps necessary for one constant.)

Never use div for known powers of 2: it's much slower than and for remainder, or right-shift for divide. Look at C compiler output for examples of unsigned or signed division by powers of 2, e.g. on the Godbolt compiler explorer. If you know a runtime input is a power of 2, use lea eax, [esi-1] ; and eax, edi or something like that to do x & (y-1). Modulo 256 is even more efficient: movzx eax, cl has zero latency on recent Intel CPUs (mov-elimination), as long as the two registers are separate.

In the simple/general case: unknown value at runtime

The DIV instruction (and its counterpart IDIV for signed numbers) gives both the quotient and remainder. For unsigned, remainder and modulus are the same thing. For signed idiv, it gives you the remainder (not modulus) which can be negative:
e.g. -5 / 2 = -2 rem -1. x86 division semantics exactly match C99's % operator.

DIV r32 divides a 64-bit number in EDX:EAX by a 32-bit operand (in any register or memory) and stores the quotient in EAX and the remainder in EDX. It faults on overflow of the quotient.

Unsigned 32-bit example (works in any mode)

mov eax, 1234          ; dividend low half
mov edx, 0             ; dividend high half = 0.  prefer  xor edx,edx

mov ebx, 10            ; divisor can be any register or memory

div ebx       ; Divides 1234 by 10.
        ; EDX =   4 = 1234 % 10  remainder
        ; EAX = 123 = 1234 / 10  quotient

In 16-bit assembly you can do div bx to divide a 32-bit operand in DX:AX by BX. See Intel's Architectures Software Developer’s Manuals for more information.

Normally always use xor edx,edx before unsigned div to zero-extend EAX into EDX:EAX. This is how you do "normal" 32-bit / 32-bit => 32-bit division.

For signed division, use cdq before idiv to sign-extend EAX into EDX:EAX. See also Why should EDX be 0 before using the DIV instruction?. For other operand-sizes, use cbw (AL->AX), cwd (AX->DX:AX), cdq (EAX->EDX:EAX), or cqo (RAX->RDX:RAX) to set the top half to 0 or -1 according to the sign bit of the low half.

div / idiv are available in operand-sizes of 8, 16, 32, and (in 64-bit mode) 64-bit. 64-bit operand-size is much slower than 32-bit or smaller on current Intel CPUs, but AMD CPUs only care about the actual magnitude of the numbers, regardless of operand-size.

Note that 8-bit operand-size is special: the implicit inputs/outputs are in AH:AL (aka AX), not DL:AL. See 8086 assembly on DOSBox: Bug with idiv instruction? for an example.

Signed 64-bit division example (requires 64-bit mode)

   mov    rax,  0x8000000000000000   ; INT64_MIN = -9223372036854775808
   mov    ecx,  10           ; implicit zero-extension is fine for positive numbers

   cqo                       ; sign-extend into RDX, in this case = -1 = 0xFF...FF
   idiv   rcx
       ; quotient  = RAX = -922337203685477580 = 0xf333333333333334
       ; remainder = RDX = -8                  = 0xfffffffffffffff8

Limitations / common mistakes

div dword 10 is not encodeable into machine code (so your assembler will report an error about invalid operands).

Unlike with mul/imul (where you should normally use faster 2-operand imul r32, r/m32 or 3-operand imul r32, r/m32, imm8/32 instead that don't waste time writing a high-half result), there is no newer opcode for division by an immediate, or 32-bit/32-bit => 32-bit division or remainder without the high-half dividend input.

Division is so slow and (hopefully) rare that they didn't bother to add a way to let you avoid EAX and EDX, or to use an immediate directly.

div and idiv will fault if the quotient doesn't fit into one register (AL / AX / EAX / RAX, the same width as the dividend). This includes division by zero, but will also happen with a non-zero EDX and a smaller divisor. This is why C compilers just zero-extend or sign-extend instead of splitting up a 32-bit value into DX:AX.

And also why INT_MIN / -1 is C undefined behaviour: it overflows the signed quotient on 2's complement systems like x86. See Why does integer division by -1 (negative one) result in FPE? for an example of x86 vs. ARM. x86 idiv does indeed fault in this case.

The x86 exception is #DE - divide exception. On Unix/Linux systems, the kernel delivers a SIGFPE arithmetic exception signal to processes that cause a #DE exception. (On which platforms does integer divide by zero trigger a floating point exception?)

For div, using a dividend with high_half < divisor is safe. e.g. 0x11:23 / 0x12 is less than 0xff so it fits in an 8-bit quotient.

Extended-precision division of a huge number by a small number can be implemented by using the remainder from one chunk as the high-half dividend (EDX) for the next chunk. This is probably why they chose remainder=EDX quotient=EAX instead of the other way around.

One other thing that you should note is that uuid.getnode() can fake the MAC addr by returning a random 48-bit number which may not be what you are expecting. Also, there's no explicit indication that the MAC address has been faked, but you could detect it by calling getnode() twice and seeing if the result varies. If the same value is returned by both calls, you have the MAC address, otherwise you are getting a faked address.

>>> print uuid.getnode.__doc__
Get the hardware address as a 48-bit positive integer.

    The first time this runs, it may launch a separate program, which could
    be quite slow.  If all attempts to obtain the hardware address fail, we
    choose a random 48-bit number with its eighth bit set to 1 as recommended
    in RFC 4122.

If above answers did not work for you then just click this link https://www.eclipse.org/downloads/packages/release/2020-06/r/eclipse-ide-enterprise-java-developers download according to your OS. And after downloading and extracting the ZIP open the extract folder and click on Eclipse application icon.

Then just enter your workspace and get started. Now you will be able to see the servers option in Window->Show View, like this:

As mentioned by jfriend00 you should not expose your server structure. You could copy your project dependency files to something like public/scripts. You can do this very easily with dep-linker like this:

var DepLinker = require('dep-linker');
DepLinker.copyDependenciesTo('./public/scripts')
// Done

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

As of git 1.7.7, git stash accepts the --include-untracked option (or short-hand -u). To include untracked files in your stash, use either of the following commands:

git stash --include-untracked
# or
git stash -u

Warning, doing this will permanently delete your files if you have any directory/ entries in your gitignore file.*

I am facing the same issue. If parent element is hidden then after showing the element chosen drop down are not showing. This is not a perfect solution but it solved my issue. After showing the element you can use following code.

function onshowelement() { $('.chosen').chosen('destroy'); $(".chosen").chosen({ width: '100%' }); }

There are several correct ways to display a down-pointing and upward-pointing triangle.

Method 1 : use decimal HTML entity

HTML :

▲
▼

Method 2 : use hexidecimal HTML entity

HTML :

▲
▼

Method 3 : use character directly

HTML :

?
?

Method 4 : use CSS

HTML :

<span class='icon-up'></span>
<span class='icon-down'></span>

CSS :

.icon-up:before {
    content: "\25B2";
}

.icon-down:before {
    content: "\25BC";
}

Each of these three methods should have the same output. For other symbols, the same three options exist. Some even have a fourth option, allowing you to use a string based reference (eg. ♥ to display ?).

You can use a reference website like Unicode-table.com to find which icons are supported in UNICODE and which codes they correspond with. For example, you find the values for the down-pointing triangle at http://unicode-table.com/en/25BC/.

Note that these methods are sufficient only for icons that are available by default in every browser. For symbols like ?,?,?,?,?,? or ?, this is far less likely to be the case. While it is possible to provide cross-browser support for other UNICODE symbols, the procedure is a bit more complicated.

If you want to know how to add support for less common UNICODE characters, see Create webfont with Unicode Supplementary Multilingual Plane symbols for more info on how to do this.

Background images

A totally different strategy is the use of background-images instead of fonts. For optimal performance, it's best to embed the image in your CSS file by base-encoding it, as mentioned by eg. @weasel5i2 and @Obsidian. I would recommend the use of SVG rather than GIF, however, is that's better both for performance and for the sharpness of your symbols.

This following code is the base64 for and SVG version of the icon :

/* size: 0.9kb */
url(data:image/svg+xml;base64,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

When to use background-images or fonts

For many use cases, SVG-based background images and icon fonts are largely equivalent with regards to performance and flexibility. To decide which to pick, consider the following differences:

SVG images

• They can have multiple colors
• They can embed their own CSS and/or be styled by the HTML document
• They can be loaded as a seperate file, embedded in CSS AND embedded in HTML
• Each symbol is represented by XML code or base64 code. You cannot use the character directly within your code editor or use an HTML entity
• Multiple uses of the same symbol implies duplication of the symbol when XML code is embedded in the HTML. Duplication is not required when embedding the file in the CSS or loading it as a seperate file
• You can not use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon, but you can reference different components of the icon as shapes individually.
• You need some knowledge of SVG and/or base64 encoding
• Limited or no support in old versions of IE

Icon fonts

• An icon can have but one fill color, one background color, etc.
• An icon can be embedded in CSS or HTML. In HTML, you can use the character directly or use an HTML entity to represent it.
• Some symbols can be displayed without the use of a webfont. Most symbols cannot.
• Multiple uses of the same symbol implies duplication of the symbol when your character embedded in the HTML. Duplication is not required when embedding the file in the CSS.
• You can use color, font-size, line-height, background-color or other font related styling rules to change the display of your icon
• You need no special technical knowledge
• Support in all major browsers, including old versions of IE

Personally, I would recommend the use of background-images only when you need multiple colors and those color can't be achieved by means of color, background-color and other color-related CSS rules for fonts.

The main benefit of using SVG images is that you can give different components of a symbol their own styling. If you embed your SVG XML code in the HTML document, this is very similar to styling the HTML. This would, however, result in a web page that uses both HTML tags and SVG tags, which could significantly reduce the readability of a webpage. It also adds extra bloat if the symbol is repeated across multiple pages and you need to consider that old versions of IE have no or limited support for SVG.

Below is a working code to add a fragment e.g 3 times to a vertical LinearLayout (xNumberLinear). You can change number 3 with any other number or take a number from a spinner!

for (int i = 0; i < 3; i++) {
            LinearLayout linearDummy = new LinearLayout(getActivity());
            linearDummy.setOrientation(LinearLayout.VERTICAL);
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {

                Toast.makeText(getActivity(), "This function works on newer versions of android", Toast.LENGTH_LONG).show();

            } else {
                linearDummy.setId(View.generateViewId());
            }
            fragmentManager.beginTransaction().add(linearDummy.getId(), new SomeFragment(),"someTag1").commit();

            xNumberLinear.addView(linearDummy);
        }

Take any web application whether it is Gmail or Facebook or Instagram or any other web application, it's all about exchanging data or information between the end user and the application or the UI and the back end application. Even in Spring MVC world there are two ways to exchange data:

1. from the Controller to the UI, and
2. from the UI to the Controller.

What we are interested here is how the data is communicated from the UI to Controller. This can also be done in 2 ways:

1. Using an HTML Form
2. Using Query Parameters.

Using an HTML Form: Consider the below scenario,

When we submit the form data from the web browser, we can access that data in our Controller class as an object. When we submit an HTML form, the Spring Container does four things. It will,

1. first read all the data that is submitted that comes in the request using the request.getParameter method.
2. once it reads them, it will convert them into the appropriate Java type using integer.parseInt, double.parseDouble and all the other parse methods that are available based on the data type of the data.
3. once parsed, it will create a object of the model class that we created. For example, in this scenario, it is the user information that is being submitted and we create a class called User, which the Container will create an object of and it will set all the values that come in automatically into that object.
4. it will then handover that object by setting the values to the Controller.

To get this whole thing to work, we'll have to follow certain steps.

We first need to define a model class, like User, in which the number of fields should exactly match the number of fields in the HTML form. Also, the names that we use in the HTML form should match the names that we have in the Java class. These two are very important. Names should match, the number of fields in the form should match the number of fields in the class that we create. Once we do that, the Container will automatically read the data that comes in, creates an object of this model, sets the values and it hands it over to the Controller. To read those values inside the Controller, we use the @ModelAttribute annotation on the method parameters. When we create methods in the Controller, we are going to use the @ModelAttribute and add a parameter to it which will automatically have this object given by the Container.

Here is an example code for registering an user:

@RequestMapping(value = "registerUser", method = RequestMethod.POST)
public String registerUser(@ModelAttribute("user") User user, ModelMap model) {
    model.addAttribute("user", user);
    return "regResult";
}

Hope this diagrammatic explanation helped!

if you want to get the whole period:

    from sqlalchemy import and_, func

    query = DBSession.query(User).filter(and_(func.date(User.birthday) >= '1985-01-17'),\
                                              func.date(User.birthday) <= '1988-01-17'))

That means range: 1985-01-17 00:00 - 1988-01-17 23:59

Change the frame size of viewcontroller.view.frame, and then add to subview. [viewcontrollerparent.view addSubview:viewcontroller.view]

If we are use chosen dropdown list, then we can use below css(No JS/JQuery require)

<select chosen="{width: '100%'}" ng- 
   model="modelName" class="form-control input- 
   sm"
   ng- 
   options="persons.persons as 
   persons.persons for persons in 
   jsonData"
   ng- 
   change="anyFunction(anyParam)" 
   required>
   <option value=""> </option>
</select>
<style>   
.chosen-container .chosen-drop {
    border-bottom: 0;
    border-top: 1px solid #aaa;
    top: auto;
    bottom: 40px;
}

.chosen-container.chosen-with-drop .chosen-single {
    border-top-left-radius: 0px;
    border-top-right-radius: 0px;

    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;

    background-image: none;
}

.chosen-container.chosen-with-drop .chosen-drop {
    border-bottom-left-radius: 0px;
    border-bottom-right-radius: 0px;

    border-top-left-radius: 5px;
    border-top-right-radius: 5px;

    box-shadow: none;

    margin-bottom: -16px;
}
</style>

There are a couple of ways that you can accomplish this. You can do the following:

<li>
     @Html.ActionLink("Clients", "Index", "User", new { @class = "elements" }, null)
</li>

or this:

<li>
     <a href="@Url.Action("Index", "Users")" class="elements">
          <span>Clients</span>
     </a>
</li>

Lately I do the following:

<a href="@Url.Action("Index", null, new { area = string.Empty, controller = "User" }, Request.Url.Scheme)">
     <span>Clients</span>
</a>

The result would have http://localhost/10000 (or with whatever port you are using) to be appended to the URL structure like:

http://localhost:10000/Users

I hope this helps.

    (select 0 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3
    ) tt
    order by tt.row

That you can do, but I think you should not break the normal flow of activity. If you want to finish you activity then you can simply send a broadcast from your activity B to activity A.

Create a broadcast receiver before starting your activity B:

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context arg0, Intent intent) {
        String action = intent.getAction();
        if (action.equals("finish_activity")) {
            finish();
            // DO WHATEVER YOU WANT.
        }
    }
};
registerReceiver(broadcastReceiver, new IntentFilter("finish_activity"));

Send broadcast from activity B to activity A when you want to finish activity A from B

Intent intent = new Intent("finish_activity");
sendBroadcast(intent);

I hope it will work for you...

An other possible solution:

for(Object it : set.toArray()) { /* Create a copy */
    Integer element = (Integer)it;
    if(element % 2 == 0)
        set.remove(element);
}

Or:

Integer[] copy = new Integer[set.size()];
set.toArray(copy);

for(Integer element : copy) {
    if(element % 2 == 0)
        set.remove(element);
}

use

 $(document).height()

  overflow=auto 

for scrolling

To print all lines in text file from command line (with delayedExpansion):

set input="path/to/file.txt"

for /f "tokens=* delims=[" %i in ('type "%input%" ^| find /v /n ""') do (

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

Try this:

First change your controller

    yourModuleName.controller("yourControllerName", function ($scope) {
        var list = [
            { H1:'A', H2:'B', H3:'C', H4:'d' },
            { H1:'E', H2:'B', H3:'F', H4:'G' },
            { H1:'C', H2:'H', H3:'L', H4:'M' },
            { H1:'I', H2:'B', H3:'E', H4:'A' }
        ];

        $scope.list = list;

        $scope.headers = ["Header1", "Header2", "Header3", "Header4"];

        $scope.sortColumn = 'Header1';

        $scope.reverseSort = false;

        $scope.sortData = function (columnIndex) {
            $scope.reverseSort = ($scope.sortColumn == $scope.headers[columnIndex]) ? !$scope.reverseSort : false;

            $scope.sortColumn = $scope.headers[columnIndex];
        }

    });

then change code in html side like this

    <th ng-repeat= "header in headers">
            <a ng-click="sortData($index)"> {{headers[$index]}} </a>
    </th>
    <tr ng-repeat "result in results | orderBy : sortColumn : reverseSort">
        <td> {{results.h1}} </td>
        <td> {{results.h2}} </td>
        <td> {{results.h3}} </td>
        <td> {{results.h4}} </td>
    </tr>

simply include parsley.js file in your document and in input element of mobile number enter this

data-parsley-type= "number" data-parsley-length="[10,10]" data-parsley-length-message= "Enter a Mobile Number"

you can change the message according to your requirement you also need to initialize parsley.js file in your document by writing

 <script type="text/javascript">

        $(document).ready(function() {
            $('form').parsley();
        });
    </script>   

---above code in your document.***

Use transform: scale(0.8); with the value you need instead of 0.8

When I try:

set guifont=Consolas:h16

I get: Warning: Font "Consolas" reports bad fixed pitch metrics

and the following is work, and don't show the waring.

autocmd vimenter * GuiFont! Consolas:h16

by the way, if you want to use the mouse wheel to control the font-size, then you can add:

function! AdjustFontSize(amount)
    let s:font_size = s:font_size + a:amount
    :execute "GuiFont! Consolas:h" . s:font_size
endfunction

noremap <C-ScrollWheelUp> :call AdjustFontSize(1)<CR>
noremap <C-ScrollWheelDown> :call AdjustFontSize(-1)<CR>

and if you want to pick the font, you can set

set guifont=*

will bring up a font requester, where you can pick the font you want.

C++11

#include <thread>

//may return 0 when not able to detect
const auto processor_count = std::thread::hardware_concurrency();

Reference: std::thread::hardware_concurrency

In C++ prior to C++11, there's no portable way. Instead, you'll need to use one or more of the following methods (guarded by appropriate #ifdef lines):

• Win32

  SYSTEM_INFO sysinfo;
  GetSystemInfo(&sysinfo);
  int numCPU = sysinfo.dwNumberOfProcessors;
  

• Linux, Solaris, AIX and Mac OS X >=10.4 (i.e. Tiger onwards)

  int numCPU = sysconf(_SC_NPROCESSORS_ONLN);
  

• FreeBSD, MacOS X, NetBSD, OpenBSD, etc.

  int mib[4];
  int numCPU;
  std::size_t len = sizeof(numCPU); 
  
  /* set the mib for hw.ncpu */
  mib[0] = CTL_HW;
  mib[1] = HW_AVAILCPU;  // alternatively, try HW_NCPU;
  
  /* get the number of CPUs from the system */
  sysctl(mib, 2, &numCPU, &len, NULL, 0);
  
  if (numCPU < 1) 
  {
      mib[1] = HW_NCPU;
      sysctl(mib, 2, &numCPU, &len, NULL, 0);
      if (numCPU < 1)
          numCPU = 1;
  }
  

• HPUX

  int numCPU = mpctl(MPC_GETNUMSPUS, NULL, NULL);
  

• IRIX

  int numCPU = sysconf(_SC_NPROC_ONLN);
  

• Objective-C (Mac OS X >=10.5 or iOS)

  NSUInteger a = [[NSProcessInfo processInfo] processorCount];
  NSUInteger b = [[NSProcessInfo processInfo] activeProcessorCount];
  

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!

The source release is the raw, uncompiled code. You could read it yourself. To use it, it must be compiled on your machine. Binary means the code was compiled into a machine language format that the computer can read, then execute. No human can understand the binary file unless its been dissected, or opened with some program that let's you read the executable as code.

In your model:

validates_presence_of :address1, message: 'Put some address please' 

In your view

<% m.errors.each do |attr, msg|  %>
 <%= msg %>
<% end %>

If you do instead

<%= attr %> <%= msg %>

you get this error message with the attribute name

address1 Put some address please

if you want to get the error message for one single attribute

<%= @model.errors[:address1] %>

According to PLINQ (available since .Net 4.0), you can do an

IEnumerable<T>.AsParallel().ForAll() 

to do a parallel foreach loop on an IEnumerable.

Following Macro can also be used to accomplish your task.

qqA,^[0jq4@q

No, they are not 0 by default. The simplest way to ensure that all values or defaulted to 0 is to define a constructor

Snapshot() : x(0), y(0) {
}

This ensures that all uses of Snapshot will have initialized values.

From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)

The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.

In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.

I came up with this function which does not mutate the original dictionary. This function also supports list of dictionaries too.

import functools
from typing import Union, Dict, List


def rename_dict_keys(
    data: Union[Dict, List[Dict]], old_key: str, new_key: str
):
    """
    This function renames dictionary keys

    :param data:
    :param old_key:
    :param new_key:
    :return: Union[Dict, List[Dict]]
    """
    if isinstance(data, dict):
        res = {k: v for k, v in data.items() if k != old_key}
        try:
            res[new_key] = data[old_key]
        except KeyError:
            raise KeyError(
                "cannot rename key as old key '%s' is not present in data"
                % old_key
            )
        return res
    elif isinstance(data, list):
        return list(
            map(
                functools.partial(
                    rename_dict_keys, old_key=old_key, new_key=new_key
                ),
                data,
            )
        )
    raise ValueError("expected type List[Dict] or Dict got '%s' for data" % type(data))

This is how you can do it-

HTML-

<div style="overflow:hidden; height:100%">
     <div style="float:left">a<br>b</div>
     <table cellpadding="0" cellspacing="0" style="height:100%;">     
          <tr><td>This is the content of a table that takes 100% height</td></tr>  
      </table>
 </div>

CSS-

html,body
{
    height:100%;
    background-color:grey;
}
table
{
    background-color:yellow;
}

See the DEMO

Update: Well, if you are not looking for applying 100% height to your parent containers, then here is a jQuery solution that should help you-

Demo-using jQuery

Script-

 $(document).ready(function(){
    var b= $(window).height(); //gets the window's height, change the selector if you are looking for height relative to some other element
    $("#tab").css("height",b);
});

Find combine result for Datatype and Length and is nullable in form of "NULL" and "Not null" Use below query.

SELECT c.name AS 'Column Name',
       t.name + '(' + cast(c.max_length as varchar(50)) + ')' As 'DataType',
       case 
         WHEN  c.is_nullable = 0 then 'null' else 'not null'
         END AS 'Constraint'
  FROM sys.columns c
  JOIN sys.types t
    ON c.user_type_id = t.user_type_id
 WHERE c.object_id    = Object_id('TableName')

you will find result as shown below.

Thank you.

Another solution that I would consider is using K9S which is a great kube administration tool.

After installation, the usage is very straightforward:

 k9s -n my-namespace --context the_context_name_in_kubeconfig

(If kubeconfig is not in the default location add KUBECONFIG=path/to/kubeconfig prefix).

The default view will list all pods as a list:

We can change the view to other Kube controllers like replica set (question asked for replication controllers so notice they are deprecated), deployments, cron jobs, etc' by entering a colon : and start typing the desired controller - as we can see K9S provides autocompletion for us:

And we can see all replica sets in the current namespace:

We can just choose the desired replica set by clicking enter and then we'll see the list of all pods which are related to this replica set - we can then press on 'l' to view logs of each pod.

So, unlike in the case of stern, we still need to go on each pod and view its logs but I think it is very convenient with K9S - we first view all pods of a related controller and then investigate logs of each pod by simply navigating with enter, l and escape.

system("COLOR 0A");'

where 0A is a combination of background and font color 0

you can use the example from Microsoft - for you without namespace:

using System.Xml.Linq;
using System.Xml.XPath;
var e = xdoc.XPathSelectElement("./Report/ReportInfo/Name");     

should do it

It looks like data not contains what you think it contains - check it.

let data={"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"};_x000D_
_x000D_
console.log( data["jobtitel"] );_x000D_
console.log( data.jobtitel );

You can also use DB::unprepared for ALTER TABLE queries.

DB::unprepared is meant to be used for queries like CREATE TRIGGER. But essentially it executes raw sql queries directly. (without using PDO prepared statements)

Many thanks to Mfoo who has put the really nice script for adding columns dynamically if not exists in the table. I have improved his answer with PHP. The script additionally helps you find how many tables actually needed 'Add column' mysql comand. Just taste the recipe. Works like charm.

<?php
ini_set('max_execution_time', 0);

$host = 'localhost';
$username = 'root';
$password = '';
$database = 'books';

$con = mysqli_connect($host, $username, $password);
if(!$con) { echo "Cannot connect to the database ";die();}
mysqli_select_db($con, $database);
$result=mysqli_query($con, 'show tables');
$tableArray = array();
while($tables = mysqli_fetch_row($result)) 
{
     $tableArray[] = $tables[0];    
}

$already = 0;
$new = 0;
for($rs = 0; $rs < count($tableArray); $rs++)
{
    $exists = FALSE;

    $result = mysqli_query($con, "SHOW COLUMNS FROM ".$tableArray[$rs]." LIKE 'tags'");
    $exists = (mysqli_num_rows($result))?TRUE:FALSE;

    if($exists == FALSE)
    {
        mysqli_query($con, "ALTER TABLE ".$tableArray[$rs]." ADD COLUMN tags VARCHAR(500) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL");
        ++$new;
        echo '#'.$new.' Table DONE!<br/>';
    }
    else
    {
        ++$already;
        echo '#'.$already.' Field defined alrady!<br/>';    
    }
    echo '<br/>';
}
?>

Just use the table name:

SELECT myTable.*, otherTable.foo, otherTable.bar...

That would select all columns from myTable and columns foo and bar from otherTable.

The correct way to use max in the having clause is by performing a self join first:

select t1.a, t1.b, t1.c
from table1 t1
join table1 t1_max
  on t1.id = t1_max.id
group by t1.a, t1.b, t1.c
having t1.date = max(t1_max.date)

The following is how you would join with a subquery:

select t1.a, t1.b, t1.c
from table1 t1
where t1.date = (select max(t1_max.date)
                 from table1 t1_max
                 where t1.id = t1_max.id)

Be sure to create a single dataset before using an aggregate when dealing with a multi-table join:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
join #dataset d_max
  on d.id = d_max.id
having d.date = max(d_max.date)
group by a, b, c

Sub query version:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
where d.date = (select max(d_max.date)
                from #dataset d_max
                where d.id = d_max.id)

I've same issue. I test this code and works well. This code Get Image from URL and put in - "bmpImage"

URL url = new URL("http://your URL");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(60000 /* milliseconds */);
            conn.setConnectTimeout(65000 /* milliseconds */);
            conn.setRequestMethod("GET");
            conn.setDoInput(true);
            conn.connect();
            int response = conn.getResponseCode();
            //Log.d(TAG, "The response is: " + response);
            is = conn.getInputStream();


            BufferedInputStream bufferedInputStream = new BufferedInputStream(is);

            Bitmap bmpImage = BitmapFactory.decodeStream(bufferedInputStream);

set width attribute as: width: fit-content

1) First of all, you must enable docker service on boot

$ sudo systemctl enable docker

2) Then if you have docker-compose .yml file add restart: always or if you have docker container add restart=always like this:

docker run --restart=always and run docker container

Make sure

If you manually stop a container, its restart policy is ignored until the Docker daemon restarts or the container is manually restarted.

see this restart policy on Docker official page

3) If you want start docker-compose, all of the services run when you reboot your system So you run below command only once

$ docker-compose up -d

My favourite hack with int or smaller enums:

GetHashCode();

For an enum

public enum Test
{
    Min = Int32.MinValue,
    One = 1,
    Max = Int32.MaxValue,
}

This,

var values = Enum.GetValues(typeof(Test));

foreach (var val in values)
{
    Console.WriteLine(val.GetHashCode());
    Console.WriteLine(((int)val));
    Console.WriteLine(val);
}

outputs

one
1
1
max
2147483647
2147483647
min
-2147483648
-2147483648

Disclaimer:

It doesn't work for enums based on long.

JSFIDDLE DEMO

If you don't want the event to be continuous (if you want the user to have to release the key each time), change onkeydown to onkeyup

window.onkeydown = function (e) {
    var code = e.keyCode ? e.keyCode : e.which;
    if (code === 38) { //up key
        alert('up');
    } else if (code === 40) { //down key
        alert('down');
    }
};

I know that question was created year ago... Anyway thanks CSS3 you can easily vertically aligns div in div (example there http://jsfiddle.net/mcSfe/98/)

<div style="width: 100px; height: 100px">
<div>
Go to Hell!
</div>
</div>

div
{
display:-moz-box;
-moz-box-align:center;
} 

You can have multiple CSS declarations for the same properties by separating them with commas:

.abc, .xyz {
   margin-left: 20px;
}

I altered Jon Skeet answer a bit for the web with extension method. It also works on azure like a charm.

public static class DateTimeWithZone
{

private static readonly TimeZoneInfo timeZone;

static DateTimeWithZone()
{
//I added web.config <add key="CurrentTimeZoneId" value="Central Europe Standard Time" />
//You can add value directly into function.
    timeZone = TimeZoneInfo.FindSystemTimeZoneById(ConfigurationManager.AppSettings["CurrentTimeZoneId"]);
}


public static DateTime LocalTime(this DateTime t)
{
     return TimeZoneInfo.ConvertTime(t, timeZone);   
}
}

It's also important to note that MongoDB has the concept of "authentication database", which can be different than the database you are connecting to. For example, if you use the official Docker image for Mongo and specify the environment variables MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD, a user will be created on 'admin' database, which is probably not the database you want to use. In this case, you should specify parameters accordingly on your application.properties file using:

spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=<username specified on MONGO_INITDB_ROOT_USERNAME>
spring.data.mongodb.password=<password specified on MONGO_INITDB_ROOT_PASSWORD>
spring.data.mongodb.database=<the db you want to use>

There are several sparse matrix classes in scipy.

bsr_matrix(arg1[, shape, dtype, copy, blocksize]) Block Sparse Row matrix
coo_matrix(arg1[, shape, dtype, copy]) A sparse matrix in COOrdinate format.
csc_matrix(arg1[, shape, dtype, copy]) Compressed Sparse Column matrix
csr_matrix(arg1[, shape, dtype, copy]) Compressed Sparse Row matrix
dia_matrix(arg1[, shape, dtype, copy]) Sparse matrix with DIAgonal storage
dok_matrix(arg1[, shape, dtype, copy]) Dictionary Of Keys based sparse matrix.
lil_matrix(arg1[, shape, dtype, copy]) Row-based linked list sparse matrix

Any of them can do the conversion.

import numpy as np
from scipy import sparse
a=np.array([[1,0,1],[0,0,1]])
b=sparse.csr_matrix(a)
print(b)

(0, 0)  1
(0, 2)  1
(1, 2)  1

$HOME/.gitconfig is your global config for git.
There are three levels of config files.

 cat $(git rev-parse --show-toplevel)/.git/config

(mentioned by bereal) is your local config, local to the repo you have cloned.

you can also type from within your repo:

git remote -v

And see if there is any remote named 'origin' listed in it.

If not, if that remote (which is created by default when cloning a repo) is missing, you can add it again:

git remote add origin url/to/your/fork

The OP mentions:

Doing git remote -v gives:

upstream git://git.moodle.org/moodle.git (fetch) 
upstream git://git.moodle.org/moodle.git (push)

So 'origin' is missing: the reference to your fork.
See "What is the difference between origin and upstream in github"

In my case issue was that numberOfRowsInSection was returning similar number of rows after calling tableView.deleteRows(...).

Since this was the required behaviour in my case, I ended up calling tableView.reloadData() instead of tableView.deleteRows(...) in cases where numberOfRowsInSection will remain same after deleting a row.

Let's say you have a column 'birth_day' in your table which is in string format, you should use the following query to filter using birth_day

date_Format(birth_day, 'yyyy-MM-dd')

You can use it in a query in the following way

select * from yourtable
where 
date_Format(birth_day, 'yyyy-MM-dd') = '2019-04-16';

Map.prototype.map = function(callback) {
  const output = new Map()
  this.forEach((element, key)=>{
    output.set(key, callback(element, key))
  })
  return output
}

const myMap = new Map([["thing1", 1], ["thing2", 2], ["thing3", 3]])
// no longer wishful thinking
const newMap = myMap.map((value, key) => value + 1)
console.info(myMap, newMap)

Depends on your religious fervor in avoiding editing prototypes, but, I find this lets me keep it intuitive.

Python equivalent code for a QMessageBox which consist of a question in it and Yes and No button. When Yes Button is clicked it will pop up another message box saying yes is clicked and same for No button also. You can push your own code after if block.

button_reply = QMessageBox.question(self,"Test", "Are you sure want to quit??", QMessageBox.Yes,QMessageBox.No,)

if button_reply == QMessageBox.Yes:
    QMessageBox.information(self, "Test", "Yes Button Was Clicked")
else :
    QMessageBox.information(self, "Test", "No Button Was Clicked")

I was getting the error A client error (403) occurred when calling the HeadObject operation: Forbidden for my aws cli copy command aws s3 cp s3://bucket/file file. I was using a IAM role which had full S3 access using an Inline Policy.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "*"
    }
  ]
}

If I give it the full S3 access from the Managed Policies instead, then the command works. I think this must be a bug from Amazon, because the policies in both cases were exactly the same.

Here's a quick way to do it, won't require anything besides sys.. though functionality is limited:

flag = "--flag" in sys.argv[1:]

[1:] is in case if the full file name is --flag

To add a star use the Unicode character 22C6.

I added a space to make a little gap between the li and the star. The code for space is A0.

li:before {
    content: '\22C6\A0';
}

There is another solution I've been using. Just create a string property and use it for json. This property wil return date properly formatted.

class JSonModel {
    ...

    [JsonIgnore]
    public DateTime MyDate { get; set; }

    [JsonProperty("date")]
    public string CustomDate {
        get { return MyDate.ToString("ddMMyyyy"); }
        // set { MyDate = DateTime.Parse(value); }
        set { MyDate = DateTime.ParseExact(value, "ddMMyyyy", null); }
    }

    ...
}

This way you don't have to create extra classes. Also, it allows you to create diferent data formats. e.g, you can easily create another Property for Hour using the same DateTime.

Try the JavaScript in operator.

if ('key' in myObj)

And the inverse.

if (!('key' in myObj))

Be careful! The in operator matches all object keys, including those in the object's prototype chain.

Use myObj.hasOwnProperty('key') to check an object's own keys and will only return true if key is available on myObj directly:

myObj.hasOwnProperty('key')

Unless you have a specific reason to use the in operator, using myObj.hasOwnProperty('key') produces the result most code is looking for.

onDestroyed()

is wrong name for

onDestroy()  

Did you make a mistake only in this question or in your code too?

Try marking the field with [NonSerialized()] attribute. This will tell the serializer to ignore the field.

Also you must agree the terms and conditions of XCode by running the following command:

sudo xcodebuild -license

Local Windows 10 ActiveMQ server :

@echo off
start /min "" "C:\Install\apache-activemq\5.15.10\bin\win64\activemq.bat" start

adb shell am broadcast -a android.intent.action.xxx

Mention xxx as the action that you mentioned in the manifest file.

I had the same problem but only for the submit button. Needed to remove the inner shadow and rounded corners -

input[type="submit"] { -webkit-appearance:none; -webkit-border-radius:0; }

CURL is AWESOME to do what you want ! It's a simple but effective command line tool.

Rest implementation test commands :

curl -i -X GET http://rest-api.io/items
curl -i -X GET http://rest-api.io/items/5069b47aa892630aae059584
curl -i -X DELETE http://rest-api.io/items/5069b47aa892630aae059584
curl -i -X POST -H 'Content-Type: application/json' -d '{"name": "New item", "year": "2009"}' http://rest-api.io/items
curl -i -X PUT -H 'Content-Type: application/json' -d '{"name": "Updated item", "year": "2010"}' http://rest-api.io/items/5069b47aa892630aae059584

We can use zPosition in ios

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

In my case see the image

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

To show the View salonDetailView upper of the mapViewUI

use zPosition as below

salonDetailView.layer.zPosition = 1

This can be accomplished using the brand new CSS display: grid (browser support)

HTML:

<div class='container'>
  <label for="dummy1">title for dummy1:</label>
  <input id="dummy1" name="dummy1" value="dummy1">
  <label for="dummy2">longer title for dummy2:</label>
  <input id="dummy2" name="dummy2" value="dummy2">
  <label for="dummy3">even longer title for dummy3:</label>
  <input id="dummy3" name="dummy3" value="dummy3">
</div>

CSS:

.container {
  display: grid;
  grid-template-columns: 1fr 3fr;
}

When using css grid, by default elements are laid out column by column then row by row. The grid-template-columns rule creates two grid columns, one which takes up 1/4 of the total horizontal space and the other which takes up 3/4 of the horizontal space. This creates the desired effect.

JS-FIDDLE

Just to add something I was missing from all the answers - even if it seems to be silly and obvious as soon as you know:

The file has to be named "App.config" or "app.config" and can be located in your project at the same level as e.g. Program.cs.

I do not know if other locations are possible, other names (like application.conf, as suggested in the ODP.net documentation) did not work for me.

PS. I started with Visual Studio Code and created a new project with "dotnet new". No configuration file is created in this case, I am sure there are other cases. PPS. You may need to add a nuget package to be able to read the config file, in case of .NET CORE it would be "dotnet add package System.Configuration.ConfigurationManager --version 4.5.0"

When i tried to make the .java to .class the command Javac didnt work. I got it working by going to C:\Program Files (x86)\Java\jdk1.7.0_04\bin and when i was on that directory I typed Javac.exe C\Test\test.java and it made the class with that tactic. Try that out.

If your page is refreshed on submitting - yes, but only through the querystring: http://www.bloggingdeveloper.com/post/JavaScript-QueryString-ParseGet-QueryString-with-Client-Side-JavaScript.aspx (You must use method "GET" then). Else, you can return its value from the php script.

If you want to update multiple rows using limit in MySQL you can use this construct:

UPDATE table_name SET name='test'
WHERE id IN (
    SELECT id FROM (
        SELECT id FROM table_name 
        ORDER BY id ASC  
        LIMIT 0, 10
    ) tmp
)

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

For me the /**<NEWLINE> or Shift-Alt-J (or ?-?-J on a Mac) approach works best.

I dislike seeing Javadoc comments in source code that have been auto-generated and have not been updated with real content. As far as I am concerned, such javadocs are nothing more than a waste of screen space.

IMO, it is much much better to generate the Javadoc comment skeletons one by one as you are about to fill in the details.

You can do in this way:

int[] numbers= {1,3,4,9,2};     
List<int> lst_numbers = new List<int>(numbers);
int required_number = 4;
int i = 0;
foreach (int number in lst_numbers)
{              
    if(number == required_number)
    {
        break;
    }
    i++;
}
lst_numbers.RemoveAt(i);
numbers = lst_numbers.ToArray();        

I found the below stuff in ffmpeg Docs. Hope this helps! :)

Reference: http://ffmpeg.org/ffmpeg.html#toc-Generic-options

‘-report’ Dump full command line and console output to a file named program-YYYYMMDD-HHMMSS.log in the current directory. This file can be useful for bug reports. It also implies -loglevel verbose.

Note: setting the environment variable FFREPORT to any value has the same effect.

Just add one more block to Ozzy's code so the thing looks like this:

public static Dimension getScaledDimension(Dimension imgSize,Dimension boundary) {

    int original_width = imgSize.width;
    int original_height = imgSize.height;
    int bound_width = boundary.width;
    int bound_height = boundary.height;
    int new_width = original_width;
    int new_height = original_height;

    // first check if we need to scale width
    if (original_width > bound_width) {
        //scale width to fit
        new_width = bound_width;
        //scale height to maintain aspect ratio
        new_height = (new_width * original_height) / original_width;
    }

    // then check if we need to scale even with the new height
    if (new_height > bound_height) {
        //scale height to fit instead
        new_height = bound_height;
        //scale width to maintain aspect ratio
        new_width = (new_height * original_width) / original_height;
    }
    // upscale if original is smaller
    if (original_width < bound_width) {
        //scale width to fit
        new_width = bound_width;
        //scale height to maintain aspect ratio
        new_height = (new_width * original_height) / original_width;
    }

    return new Dimension(new_width, new_height);
}

JAVA_OPTS is not restricted to Tomcat’s Java process, but passed to all JVM processes running on the same machine.

Use CATALINA_OPTS if you specifically want to pass JVM arguments to Tomcat's servlet engine.

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

First Try to set proxy using the following command

SET HTTPS_PROXY=http://proxy.***.com:PORT#

Then Try using the command

pip install ModuleName

Be careful when you take the exception object or the traceback object out of the exception handler, since this causes circular references and gc.collect() will fail to collect. This appears to be of a particular problem in the ipython/jupyter notebook environment where the traceback object doesn't get cleared at the right time and even an explicit call to gc.collect() in finally section does nothing. And that's a huge problem if you have some huge objects that don't get their memory reclaimed because of that (e.g. CUDA out of memory exceptions that w/o this solution require a complete kernel restart to recover).

In general if you want to save the traceback object, you need to clear it from references to locals(), like so:

import sys, traceback, gc
type, val, tb = None, None, None
try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
# some cleanup code
gc.collect()
# and then use the tb:
if tb:
    raise type(val).with_traceback(tb)

In the case of jupyter notebook, you have to do that at the very least inside the exception handler:

try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
    raise type(val).with_traceback(tb)
finally:
    # cleanup code in here
    gc.collect()

Tested with python 3.7.

p.s. the problem with ipython or jupyter notebook env is that it has %tb magic which saves the traceback and makes it available at any point later. And as a result any locals() in all frames participating in the traceback will not be freed until the notebook exits or another exception will overwrite the previously stored backtrace. This is very problematic. It should not store the traceback w/o cleaning its frames. Fix submitted here.

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

i had the same problem with my jar the solution

1. Create the MANIFEST.MF file:

Manifest-Version: 1.0

Sealed: true

Class-Path: . lib/jarX1.jar lib/jarX2.jar lib/jarX3.jar

Main-Class: com.MainClass

2. Right click on project, Select Export.

select export all outpout folders for checked project

3. select using existing manifest from workspace and select the MANIFEST.MF file

This worked for me :)

I would just query for the for attribute instead of repetitively recursing the DOM tree.

$("input:checkbox").on("change", function() {
    $("label[for='"+this.id+"']").text("TESTTTT");
});

Callee vs caller saved is a convention for who is responsible for saving and restoring the value in a register across a call. ALL registers are "global" in that any code anywhere can see (or modify) a register and those modifications will be seen by any later code anywhere. The point of register saving conventions is that code is not supposed to modify certain registers, as other code assumes that the value is not modified.

In your example code, NONE of the registers are callee save, as it makes no attempt to save or restore the register values. However, it would seem to not be an entire procedure, as it contains a branch to an undefined label (l$loop). So it might be a fragment of code from the middle of a procedure that treats some registers as callee save; you're just missing the save/restore instructions.

Table rows cannot have margin values. Can you increase the padding? That would work. Otherwise you could insert a <tr class="spacer"></tr> before and after the class="highlighted" rows.

Just to update this question for mod_security 2.7.0+ - they turned off the ability to mitigate modsec via htaccess unless you compile it with the --enable-htaccess-config flag. Most hosts do not use this compiler option since it allows too lax security. Instead, vhosts in httpd.conf are your go-to option for controlling modsec.

Even if you do compile modsec with htaccess mitigation, there are less directives available. SecRuleEngine can no longer be used there for example. Here is a list that is available to use by default in htaccess if allowed (keep in mind a host may further limit this list with AllowOverride):

    - SecAction
    - SecRule

    - SecRuleRemoveByMsg
    - SecRuleRemoveByTag
    - SecRuleRemoveById

    - SecRuleUpdateActionById
    - SecRuleUpdateTargetById
    - SecRuleUpdateTargetByTag
    - SecRuleUpdateTargetByMsg

More info on the official modsec wiki

As an additional note for 2.x users: the IfModule should now look for mod_security2.c instead of the older mod_security.c

It's a destructor. The function is guaranteed to be called when the object goes out of scope.

I know you are trying to generate your password in a specific way, but you might want to look at this method as well...

$bytes = openssl_random_pseudo_bytes(2);

$pwd = bin2hex($bytes);

It's taken from the php.net site and it creates a string which is twice the length of the number you put in the openssl_random_pseudo_bytes function. So the above would create a password 4 characters long.

In short...

$pwd = bin2hex(openssl_random_pseudo_bytes(4));

Would create a password 8 characters long.

Note however that the password only contains numbers 0-9 and small cap letters a-f!

They are essentially equivalent to each other (in fact this is how some databases implement DISTINCT under the hood).

If one of them is faster, it's going to be DISTINCT. This is because, although the two are the same, a query optimizer would have to catch the fact that your GROUP BY is not taking advantage of any group members, just their keys. DISTINCT makes this explicit, so you can get away with a slightly dumber optimizer.

When in doubt, test!

I will suppose your JPanel contains JTextField, for the sake of the demo.

Those components provides JTextComponent#setMargin() method which seems to be what you're looking for.

If you're looking for an empty border of any size around your text, well, use EmptyBorder

I experienced the same issues as Harry Johnston has mentioned. rmdir /s /q would complain that a directory was not empty even though /s is meant to do the emptying for you! I think it's a bug in Windows, personally.

My workaround is to del everything in the directory before deleting the directory itself:

del /f /s /q mydir 1>nul
rmdir /s /q mydir

(The 1>nul hides the standard output of del because otherwise, it lists every single file it deletes.)

I am using a custom static class which makes- shows and hides a dialog. this class is being used by other activities too not only one activiy. Now the problem you described also appeared to me and i have stayed overnight to find a solution..

Finally i present you the solution!

if you want to show or dismiss a dialog and you dont know which activity initiated the dialog in order to touch it then the following code is for you..

 static class CustomDialog{

     public static void initDialog(){
         ...
         //init code
         ...
     }

      public static void showDialog(){
         ...
         //init code for show dialog
         ...
     }

     /****This is your Dismiss dialog code :D*******/
     public static void dismissProgressDialog(Context context) {                
            //Can't touch other View of other Activiy..
            //http://stackoverflow.com/questions/23458162/dismiss-progress-dialog-in-another-activity-android
            if ( (progressdialog != null) && progressdialog.isShowing()) {

                //is it the same context from the caller ?
                Log.w("ProgressDIalog dismiss", "the dialog is from"+progressdialog.getContext());

                Class caller_context= context.getClass();
                Activity call_Act = (Activity)context;
                Class progress_context= progressdialog.getContext().getClass();

                Boolean is_act= ( (progressdialog.getContext()) instanceof  Activity )?true:false;
                Boolean is_ctw= ( (progressdialog.getContext()) instanceof  ContextThemeWrapper )?true:false;

                if (is_ctw) {
                    ContextThemeWrapper cthw=(ContextThemeWrapper) progressdialog.getContext();
                    Boolean is_same_acivity_with_Caller= ((Activity)(cthw).getBaseContext() ==  call_Act )?true:false;

                    if (is_same_acivity_with_Caller){
                        progressdialog.dismiss();
                        progressdialog = null;
                    }
                    else {
                        Log.e("ProgressDIalog dismiss", "the dialog is NOT from the same context! Can't touch.."+((Activity)(cthw).getBaseContext()).getClass());
                        progressdialog = null;
                    }
                }


            }
        } 

 }

list comprehension

simple implementation with list comprehension ( my favorite)

df = pd.DataFrame([pd.Series(x) for x in df.teams])
df.columns = ['team_{}'.format(x+1) for x in df.columns]

timing on output:

CPU times: user 0 ns, sys: 0 ns, total: 0 ns
Wall time: 2.71 ms

output:

team_1  team_2
0   SF  NYG
1   SF  NYG
2   SF  NYG
3   SF  NYG
4   SF  NYG
5   SF  NYG
6   SF  NYG

A random number is generated by some operation on previous value.

If there is no previous value then the current time is taken as previous value automatically. We can provide this previous value by own using random.seed(x) where x could be any number or string etc.

Hence random.random() is not actually perfect random number, it could be predicted via random.seed(x).

import random 
random.seed(45)            #seed=45  
random.random()            #1st rand value=0.2718754143840908
0.2718754143840908  
random.random()            #2nd rand value=0.48802820785090784
0.48802820785090784  
random.seed(45)            # again reasign seed=45  
random.random()
0.2718754143840908         #matching with 1st rand value  
random.random()
0.48802820785090784        #matching with 2nd rand value

Hence, generating a random number is not actually random, because it runs on algorithms. Algorithms always give the same output based on the same input. This means, it depends on the value of the seed. So, in order to make it more random, time is automatically assigned to seed().

As far as I have researched,

Use : 1. When you are using an svg sprite. 2. When your images are of a lesser size (max 200mb).

Don't Use : 1. When you are bigger images. 2. Icons as svg's. As they are already good and gzipped after compression.

Element.children returns only element children, while Node.childNodes returns all node children. Note that elements are nodes, so both are available on elements.

I believe childNodes is more reliable. For example, MDC (linked above) notes that IE only got children right in IE 9. childNodes provides less room for error by browser implementors.

If you are using this in chrome/chromium browser(ex: in Ubuntu 14.04), You can use one of the below command to tackle this issue.

ThinkPad-T430:~$ google-chrome --allow-file-access-from-files
ThinkPad-T430:~$ google-chrome --allow-file-access-from-files fileName.html

ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files
ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files fileName.html

This will allow you to load the file in chrome or chromium. If you have to do the same operation for windows you can add this switch in properties of the chrome shortcut or run it from cmd with the flag. This operation is not allowed in Chrome, Opera, Internet Explorer by default. By default it works only in firefox and safari. Hence using this command will help you.

Alternately you can also host it on any web server (Example:Tomcat-java,NodeJS-JS,Tornado-Python, etc) based on what language you are comfortable with. This will work from any browser.

Use the following: spinnerObject.setSelection(INDEX_OF_CATEGORY2).

I'm only including code because the code posted so far seems suboptimal (and I don't have the rep to comment yet.)

void inplace_trim(char* s)
{
    int start, end = strlen(s);
    for (start = 0; isspace(s[start]); ++start) {}
    if (s[start]) {
        while (end > 0 && isspace(s[end-1]))
            --end;
        memmove(s, &s[start], end - start);
    }
    s[end - start] = '\0';
}

char* copy_trim(const char* s)
{
    int start, end;
    for (start = 0; isspace(s[start]); ++start) {}
    for (end = strlen(s); end > 0 && isspace(s[end-1]); --end) {}
    return strndup(s + start, end - start);
}

strndup() is a GNU extension. If you don't have it or something equivalent, roll your own. For example:

r = strdup(s + start);
r[end-start] = '\0';

Bergi's solution works nicely when fs is promise based. You can use bluebird, fs-extra or fs-promise for this.

However, solution for node's native fs libary is as follows:

const result = await Promise.all(filePaths
    .map( async filePath => {
      const fileContents = await getAssetFromCache(filePath, async function() {

        // 1. Wrap with Promise    
        // 2. Return the result of the Promise
        return await new Promise((res, rej) => {
          fs.readFile(filePath, 'utf8', function(err, data) {
            if (data) {
              res(data);
            }
          });
        });
      });

      return fileContents;
    }));

Note: require('fs') compulsorily takes function as 3rd arguments, otherwise throws error:

TypeError [ERR_INVALID_CALLBACK]: Callback must be a function

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

In case you are using ES6 you can do:

const arr = [ 1, 2, 3 ];
[ ...arr ].pop(); // 3
arr; // [ 1, 2, 3 ] (wasn't changed)

*my_map.begin(). See e.g. http://cplusplus.com/reference/stl/map/begin/.

If git config --global user.email "[email protected]" git config --global user.name "github_username"

Dont work like in my case, you can use:

git config --replace-all user.email "[email protected]"
git config --replace-all user.name "github_username"

No, HTML is not a programming language. The "M" stands for "Markup". Generally, a programming language allows you to describe some sort of process of doing something, whereas HTML is a way of adding context and structure to text.

If you're looking to add more alphabet soup to your CV, don't classify them at all. Just put them in a big pile called "Technologies" or whatever you like. Remember, however, that anything you list is fair game for a question.

HTML is so common that I'd expect almost any technology person to already know it (although not stuff like CSS and so on), so you might consider not listing every initialism you've ever come across. I tend to regard CVs listing too many things as suspicious, so I ask more questions to weed out the stuff that shouldn't be listed. :)

However, if your HTML experience includes serious web design stuff including Ajax, JavaScript, and so on, you might talk about those in your "Experience" section.

MongoDB shell version v4.2.6
Node v14.2.0

Assuming you have a Tour Model: tourModel.js

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true,
    trim: true,
  },
  createdAt: {
    type: Date,
    default: Date.now(),
  },
});
const Tour = mongoose.model('Tour', tourSchema);

module.exports = Tour;

Now you want to delete all tours at once from your MongoDB, I also providing connection code to connect with the remote cluster. I used deleteMany(), if you do not pass any args to deleteMany(), then it will delete all the documents in Tour collection.

const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');
const conStr = 'mongodb+srv://lord:<PASSWORD>@cluster0-eeev8.mongodb.net/tour-guide?retryWrites=true&w=majority';
const DB = conStr.replace('<PASSWORD>','ADUSsaZEKESKZX');
mongoose.connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true,
  })
  .then((con) => {
    console.log(`DB connection successful ${con.path}`);
  });

const deleteAllData = async () => {

update YourTable
    set YourColumn = replace(YourColumn, '@domain2', '@domain1')
    where charindex('@domain2', YourColumn) <> 0

Just to Elaborate an alternate method and a Use case for which it is helpful:

• Subtract 1 day from current datetime:

from datetime import datetime, timedelta
print datetime.now() + timedelta(days=-1)  # Here, I am adding a negative timedelta

• Useful in the Case, If you want to add 5 days and subtract 5 hours from current datetime. i.e. What is the Datetime 5 days from now but 5 hours less ?

from datetime import datetime, timedelta
print datetime.now() + timedelta(days=5, hours=-5)

It can similarly be used with other parameters e.g. seconds, weeks etc

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Use build job plugin for that task in order to trigger other jobs from jenkins file. You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs. I gave some easy-to-read cookbook example for that.

1.example for triggering external job from jenkins file with conditional example:

if (env.BRANCH_NAME == 'master') {
  build job:'exactJobName' , parameters:[
    string(name: 'keyNameOfParam1',value: 'valueOfParam1')
    booleanParam(name: 'keyNameOfParam2',value:'valueOfParam2')
 ]
}

2.example triggering multiple jobs from jenkins file with conditionals example:

 def jobs =[
    'job1Title'{
    if (env.BRANCH_NAME == 'master') {
      build job:'exactJobName' , parameters:[
        string(name: 'keyNameOfParam1',value: 'valueNameOfParam1')
        booleanParam(name: 'keyNameOfParam2',value:'valueNameOfParam2')
     ]
    }
},
    'job2Title'{
    if (env.GIT_COMMIT == 'someCommitHashToPerformAdditionalTest') {
      build job:'exactJobName' , parameters:[
        string(name: 'keyNameOfParam3',value: 'valueOfParam3')
        booleanParam(name: 'keyNameOfParam4',value:'valueNameOfParam4')
        booleanParam(name: 'keyNameOfParam5',value:'valueNameOfParam5')
     ]
    }
}

As it has been outlined here, because Google is sending an "X-Frame-Options: SAMEORIGIN" response header you cannot simply set the src to "http://www.google.com" in a iframe.

If you want to embed Google into an iframe you can do what sudopeople suggested in a comment above and use a Google custom search link like the following. This worked great for me (left 'q=' blank to start with blank search).

<iframe id="if1" width="100%" height="254" style="visibility:visible" src="http://www.google.com/custom?q=&btnG=Search"></iframe>

EDIT:

This answer no longer works. For information, and instructions on how to replace an iframe search with a google custom search element check out: https://support.google.com/customsearch/answer/2641279

I do recomend doing it in 2 filles (.h .cpp) But if u lazy just add inline before the function So it will look something like this

inline void functionX() 
{ }

more about inline functions:

The inline functions are a C++ enhancement feature to increase the execution time of a program. Functions can be instructed to compiler to make them inline so that compiler can replace those function definition wherever those are being called. Compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime. NOTE- This is just a suggestion to compiler to make the function inline, if function is big (in term of executable instruction etc) then, compiler can ignore the “inline” request and treat the function as normal function.

For the hell of it...

This solution is different to all earlier solutions, viz:

• There is no need to create a function
• There is no need to use pattern matching
• There is no need for a temporary table
• This solution uses a recursive common table expression (CTE)

But first - note the question does not specify where such strings are stored. In my solution below, I create a CTE as a quick and dirty way to put these strings into some kind of "source table".

Note also - this solution uses a recursive common table expression (CTE) - so don't get confused by the usage of two CTEs here. The first is simply to make the data avaliable to the solution - but it is only the second CTE that is required in order to solve this problem. You can adapt the code to make this second CTE query your existing table, view, etc.

Lastly - my coding is verbose, trying to use column and CTE names that explain what is going on and you might be able to simplify this solution a little. I've added in a few pseudo phone numbers with some (expected and atypical, as the case may be) formatting for the fun of it.

with SOURCE_TABLE as (
    select '003Preliminary Examination Plan' as numberString
    union all select 'Coordination005' as numberString
    union all select 'Balance1000sheet' as numberString
    union all select '1300 456 678' as numberString
    union all select '(012) 995 8322  ' as numberString
    union all select '073263 6122,' as numberString
),
FIRST_CHAR_PROCESSED as (
    select
        len(numberString) as currentStringLength,
        isNull(cast(try_cast(replace(left(numberString, 1),' ','z') as tinyint) as nvarchar),'') as firstCharAsNumeric,
        cast(isNull(cast(try_cast(nullIf(left(numberString, 1),'') as tinyint) as nvarchar),'') as nvarchar(4000)) as newString,
        cast(substring(numberString,2,len(numberString)) as nvarchar) as remainingString
    from SOURCE_TABLE
    union all
    select
        len(remainingString) as currentStringLength,
        cast(try_cast(replace(left(remainingString, 1),' ','z') as tinyint) as nvarchar) as firstCharAsNumeric,
        cast(isNull(newString,'') as nvarchar(3999)) + isNull(cast(try_cast(nullIf(left(remainingString, 1),'') as tinyint) as nvarchar(1)),'') as newString,
        substring(remainingString,2,len(remainingString)) as remainingString
    from FIRST_CHAR_PROCESSED fcp2
    where fcp2.currentStringLength > 1
)
select 
    newString
    ,* -- comment this out when required
from FIRST_CHAR_PROCESSED 
where currentStringLength = 1

So what's going on here?

Basically in our CTE we are selecting the first character and using try_cast (see docs) to cast it to a tinyint (which is a large enough data type for a single-digit numeral). Note that the type-casting rules in SQL Server say that an empty string (or a space, for that matter) will resolve to zero, so the nullif is added to force spaces and empty strings to resolve to null (see discussion) (otherwise our result would include a zero character any time a space is encountered in the source data).

The CTE also returns everything after the first character - and that becomes the input to our recursive call on the CTE; in other words: now let's process the next character.

Lastly, the field newString in the CTE is generated (in the second SELECT) via concatenation. With recursive CTEs the data type must match between the two SELECT statements for any given column - including the column size. Because we know we are adding (at most) a single character, we are casting that character to nvarchar(1) and we are casting the newString (so far) as nvarchar(3999). Concatenated, the result will be nvarchar(4000) - which matches the type casting we carry out in the first SELECT.

If you run this query and exclude the WHERE clause, you'll get a sense of what's going on - but the rows may be in a strange order. (You won't necessarily see all rows relating to a single input value grouped together - but you should still be able to follow).

Hope it's an interesting option that may help a few people wanting a strictly expression-based solution.

I know this is an old question, but I thought I would share this little trick.

var diff = $(old_array).not(new_array).get();

diff now contains what was in old_array that is not in new_array

tl;dr: downgrade java by running update-alternatives

My system gradle version was 4.4.1, and the gradle wrapper version was 4.0. After running the command given by several other answers:

gradle wrapper --gradle-version 4.4.1

I still had the same error:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.4'.

It turns out java 11 wasn't supported until gradle 4.8, and my software repositories only had 4.4.1. (Also, upgrading to newer gradle version might have been incompatible with the package I was trying to compile.)

The answer was to downgrade java. My system actually had java8 already installed, and it was easy to switch between java versions by running this command and following the instructions:

sudo update-alternatives --config java

What are you using to compile this? If there's an undefined reference error, usually it's because the .o file (which gets created from the .cpp file) doesn't exist and your compiler/build system is not able to link it.

Also, in your card.cpp, the function should be Card::Card() instead of void Card. The Card:: is scoping; it means that your Card() function is a member of the Card class (which it obviously is, since it's the constructor for that class). Without this, void Card is just a free function. Similarly,

void Card(Card::Rank rank, Card::Suit suit)

should be

Card::Card(Card::Rank rank, Card::Suit suit)

Also, in deck.cpp, you are saying #include "Deck.h" even though you referred to it as deck.h. The includes are case sensitive.

Yes.

(T)Activator.CreateInstance(typeof(T), param1, param2);

When you provide a path, it can be absolute/rooted, or relative. If you provide a relative path, it will be resolved by taking the working directory of the running process.

Example:

string text = File.ReadAllText("Some\\Path.txt"); // relative path

The above code has the same effect as the following:

string text = File.ReadAllText(
    Path.Combine(Environment.CurrentDirectory, "Some\\Path.txt"));

If you have files that are always going to be in the same location relative to your application, just include a relative path to them, and they should resolve correctly on different computers.

Use this to get an admin window with either bash or cmd running, from any directories context menue. Just right click on a directory name, and select the entry or hit the highlited button.

This is based on the chere tool and the unfortunately not working answer (for me) from link_boy. It works fine for me using Windows 8,

A side effect is the different color in the admin cmd window. To use this on bash, you can change the .bashrc file of the admin user.

I coudln't get the "background" version (right click into an open directory) to run. Feel free to add it.

The main problem here is content type [text/html;charset=iso-8859-1] received from the service, however the real content type should be application/json;charset=iso-8859-1

In order to overcome this you can introduce custom message converter. and register it for all kind of responses (i.e. ignore the response content type header). Just like this

List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();        
//Add the Jackson Message converter
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();

// Note: here we are making this converter to process any kind of response, 
// not only application/*json, which is the default behaviour
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));        
messageConverters.add(converter);  
restTemplate.setMessageConverters(messageConverters); 

With image and confirmation on delete, which works on mozilla firefox

            display: block;
            height: 15px;
            width: 15px;

        }
</style>

It's possible to scale NodeJS out to multiple boxes using a pure TCP load balancer (HAProxy) in front of multiple boxes running one NodeJS process each.

If you then have some common knowledge to share between all instances you could use a central Redis store or similar which can then be accessed from all process instances (e.g. from all boxes)

The UIWindow.tintColor method wasn't working for me in iOS8 (it was still black), so I had to do this:

let b = UIButton.buttonWithType(UIButtonType.System) as UIButton
var color = b.titleColorForState(.Normal)

This gave the proper blue tint seen in a UIBarButtonItem

A Popen object has a .wait() method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).

If you use this method, you'll prevent that the process zombies are lying around for too long.

(Alternatively, you can use subprocess.call() or subprocess.check_call() for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_)call().)

If you have several subprocesses to wait for, you can do

exit_codes = [p.wait() for p in p1, p2]

which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.

@guest-418 tips works well:

adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db

However, if you want to use a GUI, use Android Studio's Device File Explorer.

1. Launch Android Studio

2. Click on Device File Explorer at bottom right-side Navigate to your app's file:

   /data/data/path.to.package/databases/data

3. Right-mouse click select Save As and save to a local folder

I have been having Android Monitor hang on me lately on macOS. Device File Explorer works well for this purpose.

A word of caution regarding handrolled approaches:

I'm disappointed to see that some of the suggested code examples in this post do not protect against such fundamental authentication vulnerabilities such as session fixation or timing attacks.

Contrary to several suggestions here, authentication is not simple and handrolling a solution is not always trivial. I would recommend passportjs and bcrypt.

If you do decide to handroll a solution however, have a look at the express js provided example for inspiration.

Good luck.

Express is basically a wrapper of http module that is created for the ease of the developers in such a way that..

1. They can set up middlewares to respond to HTTP Requests (easily) using express.
2. They can dynamically render HTML Pages based on passing arguments to templates using express.
3. They can also define routing easily using express.

Great answer by F.Mörk. But if you want to update translation, or add new languages once the application is released, you're stuck, because you always have to recompile it to generate the resources.dll.

Here is a solution to manually compile a resource dll. It uses the resgen.exe and al.exe tools (installed with the sdk).

Say you have a Strings.fr.resx resource file, you can compile a resources dll with the following batch:

resgen.exe /compile Strings.fr.resx,WpfRibbonApplication1.Strings.fr.resources 
Al.exe /t:lib /embed:WpfRibbonApplication1.Strings.fr.resources /culture:"fr" /out:"WpfRibbonApplication1.resources.dll"
del WpfRibbonApplication1.Strings.fr.resources
pause

Be sure to keep the original namespace in the file names (here "WpfRibbonApplication1")

A less robust approach, but it works.

a = [2, 4, 5].toString();
b = [2, 4, 5].toString();

console.log(a===b);

If your string is in ISO 8601 format, you can also use from_iso8601_timestamp

has_key was removed in Python 3. From the documentation:

• Removed dict.has_key() – use the in operator instead.

Here's an example:

if start not in graph:
    return None

You may use + or << operator, but in ruby .concat function is the most preferable one, as it is much faster than other operators. You can use it like.

source = "#{ROOT_DIR}/".concat(project.concat("/App.config"))

In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...

Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate. For instance, you are on master and have local commits, and git fetch has brought new upstream commits into origin/master. The branch now diverges from its upstream and cannot be fast forwarded: your master HEAD commit is not an ancestor of origin/master HEAD. To simply reset master to the value of origin/master would discard your local commits. The situation requires a rebase or merge.

If your local master has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master. Usually, no special steps are needed to do fast-forwarding; it is done by merge or rebase in the situation when there are no local commits.

Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?

No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

in case if your table has tbody

let tbl = document.getElementById("tbl").getElementsByTagName('tbody')[0];
console.log(tbl.rows[0].cells[0].innerHTML)

in case the number of digits AND the value of each digit position is needed use this:

int64_t = number, digitValue, digits = 0;    // or "int" for 32bit

while (number != 0) {
    digitValue = number % 10;
    digits ++;
    number /= 10;
}

digit gives you the value at the number postition which is currently processed in the loop. for example for the number 1776 the digit value is:
6 in the 1st loop
7 in the 2nd loop
7 in the 3rd loop
1 in the 4th loop

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'student'

$query = DB::table('dms_stakeholder_permissions');
$query->select(DB::raw('group_concat(dms_stakeholder_permissions.fid) as fid'),'dms_stakeholder_permissions.rights');
$query->where('dms_stakeholder_permissions.stakeholder_id','4');
$query->orWhere(function($subquery)  use ($stakeholderId){
            $subquery->where('dms_stakeholder_permissions.stakeholder_id',$stakeholderId);
            $subquery->whereIn('dms_stakeholder_permissions.rights',array('1','2','3'));
    });

 $result = $query->get();

return $result;

// OUTPUT @input $stakeholderId = 1

//select group_concat(dms_stakeholder_permissions.fid) as fid, dms_stakeholder_permissionss.rights from dms_stakeholder_permissions where dms_stakeholder_permissions.stakeholder_id = 4 or (dms_stakeholder_permissions.stakeholder_id = 1 and dms_stakeholder_permissions.rights in (1, 2, 3))

if you do any changes on git ignore then you have to clear you git cache also

> git rm -r --cached . 
> git add . 
> git commit -m 'git cache cleared'
> git push

if want to remove any particular folder or file then

git rm  --cached filepath/foldername

You can do it with an UPDATE statement setting the value with a REPLACE

UPDATE
    Table
SET
    Column = Replace(Column, 'find value', 'replacement value')
WHERE
    xxx

You will want to be extremely careful when doing this! I highly recommend doing a backup first.

Use .parentsUntil()

$(".d").parentsUntil(".a");

What I did in the end is make a batch file to extract the CLASSPATH from the ant file, then run java directly using this:

In my build.xml:

<target name="printclasspath">
    <pathconvert property="classpathProp" refid="project.class.path"/>
    <echo>${classpathProp}</echo>
</target>

In another script called 'run.sh':

export CLASSPATH=$(ant -q printclasspath | grep echo | cut -d \  -f 7):build
java "$@"

It's no longer cross-platform, but at least it's relatively easy to use, and one could provide a .bat file that does the same as the run.sh. It's a very short batch script. It's not like migrating the entire build to platform-specific batch files.

I think it's a shame there's not some option in ant whereby you could do something like:

ant -- arg1 arg2 arg3

mpirun uses this type of syntax; ssh also can use this syntax I think.

This class will help and then initialize the class with the init method.

import 'package:flutter/widgets.dart';

class SizeConfig {
  static MediaQueryData _mediaQueryData;
  static double screenWidth;
  static double screenHeight;
  static double blockSizeHorizontal;
  static double blockSizeVertical;
  static double _safeAreaHorizontal;
  static double _safeAreaVertical;
  static double safeBlockHorizontal;
  static double safeBlockVertical;

  void init(BuildContext context){
    _mediaQueryData = MediaQuery.of(context);
    screenWidth = _mediaQueryData.size.width;
    screenHeight = _mediaQueryData.size.height;
    blockSizeHorizontal = screenWidth/100;
    blockSizeVertical = screenHeight/100;
    _safeAreaHorizontal = _mediaQueryData.padding.left +
        _mediaQueryData.padding.right;
    _safeAreaVertical = _mediaQueryData.padding.top +
        _mediaQueryData.padding.bottom;
    safeBlockHorizontal = (screenWidth - _safeAreaHorizontal)/100;
    safeBlockVertical = (screenHeight - _safeAreaVertical)/100;
  }
}

then in your widgets dimension do this

Widget build(BuildContext context) {
    SizeConfig().init(context);
    return Container(
    height: SizeConfig.safeBlockVertical * 10, //10 for example
    width: SizeConfig.safeBlockHorizontal * 10, //10 for example
    );}

You need to adjust shell path , the path will be set in either .bashrc or .bash_profile in your home directory, more likely .bash_profile.

So add into the path similar to the below and keep what you already have in the path, each segment is separated by a colon:

export PATH="/usr/local/bin:/usr/bin/git:/usr/bin:/usr/local/sbin:$PATH"

I had the same problem for my project Ratio.js and here's what I did.

Problem: Github.com prevents files from rendering/executing when the source is viewed by setting the content type/MIME to plain text.

Solution: Have a web page import the files.

Example:

Use jsfiddle.net or jsbin.com to create a webpage online then save it. Navigate to your file in Github.com and click the 'raw' button to get the direct link to the file. From there, import the file using the appropriate tag and attribute.

Note: Note for jsfiddle.net you can get direct access to the result page by adding show to the end of the url. Like so: http://jsfiddle.net/jKu4q/2/show

Or....you could create a project page and render your HTML files from there. You can create a project page at http://pages.github.com/.

Once created you can then access the link through http://*accountName*.github.com/*projectName*/ Example: http://larrybattle.github.com/Ratio.js/

.aspx uses a full lifecycle (Init, Load, PreRender) and can respond to button clicks etc.
An .ashx has just a single ProcessRequest method.

Try using the ACQUIRE_CAUSES_WAKEUP flag when you create the wake lock. The ON_AFTER_RELEASE flag just resets the activity timer to keep the screen on a bit longer.

Based on @Ted's answer, I've used this extension:

extension XCTestCase {

    // Based on https://stackoverflow.com/a/33855219
    func waitFor<T>(object: T, timeout: TimeInterval = 5, file: String = #file, line: UInt = #line, expectationPredicate: @escaping (T) -> Bool) {
        let predicate = NSPredicate { obj, _ in
            expectationPredicate(obj as! T)
        }
        expectation(for: predicate, evaluatedWith: object, handler: nil)

        waitForExpectations(timeout: timeout) { error in
            if (error != nil) {
                let message = "Failed to fulful expectation block for \(object) after \(timeout) seconds."
                let location = XCTSourceCodeLocation(filePath: file, lineNumber: line)
                let issue = XCTIssue(type: .assertionFailure, compactDescription: message, detailedDescription: nil, sourceCodeContext: .init(location: location), associatedError: nil, attachments: [])
                self.record(issue)
            }
        }
    }

}

You can use it like this

let element = app.staticTexts["Name of your element"]
waitFor(object: element) { $0.exists }

It also allows for waiting for an element to disappear, or any other property to change (by using the appropriate block)

waitFor(object: element) { !$0.exists } // Wait for it to disappear

Maybe you could try

List<Article> findAllByPublicationDate(Date publicationDate);

The detail could be checked in this article:

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.

$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);

Following these steps worked for me:

• Click on your project name (very top of the navigator)
• Click on your project name again, (not on target)
• Click the tab Build Settings

• Search for Runpath Search Paths

• Change its value to $(inherited) flag (remove @executable_path/Frameworks).

I think the correct syntax is:

cmd /k "cd c:\<folder name>"

If you have for instance in your package.json file:

{
"name": "zig-zag",
"main": "lib/entry.js",
...
}

lib/entry.js will be the main entry point to your package.

When calling

require('zig-zag');

in node, lib/entry.js will be the actual file that is required.

Adding a new row in a DGV with no rows with Add() raises SelectionChanged event before you can insert any data (or bind an object in Tag property).

Create a clone row from RowTemplate is safer imho:

//assuming that you created columns (via code or designer) in myDGV
DataGridViewRow row = (DataGridViewRow) myDGV.RowTemplate.Clone();
row.CreateCells(myDGV, "cell1", "cell2", "cell3");

myDGV.Rows.Add(row);

Xcode 8.3.2 Swift 3.x. Using NSKeyedArchiver and NSKeyedUnarchiver

Reading file from documents

let documentsDirectoryPathString = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
let documentsDirectoryPath = NSURL(string: documentsDirectoryPathString)!
let jsonFilePath = documentsDirectoryPath.appendingPathComponent("Filename.json")

let fileManager = FileManager.default
var isDirectory: ObjCBool = false

if fileManager.fileExists(atPath: (jsonFilePath?.absoluteString)!, isDirectory: &isDirectory) {

let finalDataDict = NSKeyedUnarchiver.unarchiveObject(withFile: (jsonFilePath?.absoluteString)!) as! [String: Any]
}
else{
     print("File does not exists")
}

Write file to documents

NSKeyedArchiver.archiveRootObject(finalDataDict, toFile:(jsonFilePath?.absoluteString)!)

Try This:

CGSize scrollSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, scrollHeight);
[scrollView setContentSize: scrollSize];

This article can be super helpful to understand strong, soft, weak and phantom references.

To give you a summary,

If you only have weak references to an object (with no strong references), then the object will be reclaimed by GC in the very next GC cycle.

If you only have soft references to an object (with no strong references), then the object will be reclaimed by GC only when JVM runs out of memory.

So you can say that, strong references have ultimate power (can never be collected by GC)

Soft references are powerful than weak references (as they can escape GC cycle until JVM runs out of memory)

Weak references are even less powerful than soft references (as they cannot excape any GC cycle and will be reclaimed if object have no other strong reference).

Restaurant Analogy

• Waiter - GC
• You - Object in heap
• Restaurant area/space - Heap space
• New Customer - New object that wants table in restaurant

Now if you are a strong customer (analogous to strong reference), then even if a new customer comes in the restaurant or what so ever happnes, you will never leave your table (the memory area on heap). The waiter has no right to tell you (or even request you) to leave the restaurant.

If you are a soft customer (analogous to soft reference), then if a new customer comes in the restaurant, the waiter will not ask you to leave the table unless there is no other empty table left to accomodate the new customer. (In other words the waiter will ask you to leave the table only if a new customer steps in and there is no other table left for this new customer)

If you are a weak customer (analogous to weak reference), then waiter, at his will, can (at any point of time) ask you to leave the restaurant :P

This is for vmware workstation 6.5

It is pretty far down.

select Create new virtual machine -> select custom ->
on compatibility page take defaults ->
check I will install os later -> click through several pages choosing other for OS, give it a name, make sure it IS NOT in the same folder as the VMDK file. Choose bridged network.

You will now see a screen asking to select disk, select existing virual disk. then browse and select the VMDK file

The easiest way to have different configurations for different environments is to use spring profiles. See externalised configuration.

This gives you a lot of flexibility. I am using it in my projects and it is extremely helpful. In your case you would have 3 profiles: 'local', 'jenkins', and 'openshift'

You then have 3 profile specific property files: application-local.properties, application-jenkins.properties, and application-openshift.properties

There you can set the properties for the regarding environment. When you run the app you have to specify the profile to activate like this: -Dspring.profiles.active=jenkins

Edit

According to the spring doc you can set the system environment variable SPRING_PROFILES_ACTIVE to activate profiles and don't need to pass it as a parameter.

is there any way to pass active profile option for web app at run time ?

No. Spring determines the active profiles as one of the first steps, when building the application context. The active profiles are then used to decide which property files are read and which beans are instantiated. Once the application is started this cannot be changed.

My task was to implement ListView which expands when clicked. The additional space shows EditText where you can input some text. App should be functional on 2.2+ (up to 4.2.2 at time of writing this)

I tried numerous solutions from this post and others I could find; tested them on 2.2 up to 4.2.2 devices. None of solutions was satisfactionary on all devices 2.2+, each solution presented with different problems.

I wanted to share my final solution :

1. set listview to android:descendantFocusability="afterDescendants"
2. set listview to setItemsCanFocus(true);
3. set your activity to android:windowSoftInputMode="adjustResize" Many people suggest adjustPan but adjustResize gives much better ux imho, just test this in your case. With adjustPan you will get bottom listitems obscured for instance. Docs suggest that ("This is generally less desirable than resizing"). Also on 4.0.4 after user starts typing on soft keyboard the screen pans to the top.
4. on 4.2.2 with adjustResize there are some problems with EditText focus. The solution is to apply rjrjr solution from this thread. It looks scarry but it is not. And it works. Just try it.

Additional 5. Due to adapter being refreshed (because of view resize) when EditText gains focus on pre HoneyComb versions I found an issue with reversed views: getting View for ListView item / reverse order on 2.2; works on 4.0.3

If you are doing some animations you might want to change behaviour to adjustPan for pre-honeycomb versions so that resize doesnt fire and adapter doesn't refresh the views. You just need to add something like this

if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB)
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

All this gives acceptable ux on 2.2 - 4.2.2 devices. Hope it will save people some time as it took me at least several hours to come to this conclusion.

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

_var has no meaning and only serves the purpose of making it easier to distinguish that the variable is a private member variable.

In C++, using the _var convention is bad form, because there are rules governing the use of the underscore in front of an identifier. _var is reserved as a global identifier, while _Var (underscore + capital letter) is reserved anytime. This is why in C++, you'll see people using the var_ convention instead.

Create simple drop-down menu using HTML and CSS

CSS:

<style>
.dropdown {
    position: relative;
    display: inline-block;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    padding: 12px 16px;
    z-index: 1;
}

.dropdown:hover .dropdown-content {
    display: block;
}
</style>

and HTML:

<div class="dropdown">
  <span>Mouse over me</span>
  <div class="dropdown-content">
    <p>Hello World!</p>
  </div>
</div>

View demo online

$('html, body').animate({scrollTop: $("#page").offset().top}, 2000);

The best way depends a lot on the platform(s) being targeted, debug vs. release usage etc.

I don't think there is one best way, but to "force" a wait on enter type scenario in a fairly generic way, especially when debugging (typically this is either compiled in or out based on NDEBUG or _DEBUG), you could try std::getline as follows

inline void wait_on_enter()
{
    std::string dummy;
    std::cout << "Enter to continue..." << std::endl;
    std::getline(std::cin, dummy);
}

With our without the "enter to continue", as needed.

Git Graph seems like a decent extension. After installing, you can open the graph view from the bottom status bar.

Not pretty, but here is a way to implement an exit() command in R which works for me.

exit <- function() {
  .Internal(.invokeRestart(list(NULL, NULL), NULL))
}

print("this is the last message")
exit()
print("you should not see this")

Only lightly tested, but when I run this, I see this is the last message and then the script aborts without any error message.

It 'a permission problem when IIS is running I had this problem and I solved it in this way

I went on folders

C:\Windows\ System32\config\SystemProfile

and

C:\Windows\SysWOW64\config\SystemProfile

are protected system folders, they usually have the lock.

Right-click-> Card security-> Click on Edit-> Add untente "Autenticadet User" and assign permissions.

At this point everything is solved, if you still have problems try to give all permissions to "Everyone"

When we work on development environment and merge our code to staging/production branch then Git no fast forward can be a better option. Usually when we work in development branch for a single feature we tend to have multiple commits. Tracking changes with multiple commits can be inconvenient later on. If we merge with staging/production branch using Git no fast forward then it will have only 1 commit. Now anytime we want to revert the feature, just revert that commit. Life is easy.

Michael's suggestion of running your own nbviewer instance is a good one I used in the past with an Enterprise Github server.

Another lightweight alternative is to have a cell at the end of your notebook that does a shell call to nbconvert so that it's automatically refreshed after running the whole thing:

!ipython nbconvert <notebook name>.ipynb --to html

EDIT: With Jupyter/IPython's Big Split, you'll probably want to change this to !jupyter nbconvert <notebook name>.ipynb --to html now.

Really simple way is:

pip install simplejson

VBScript does not have a method for sorting arrays so you've got two options:

• Writing a sorting function like mergesort, from ground up.
• Use the JScript tip from this article

All the above answers are correct, but I noticed something very important. Leaving a space between the variable and the equal sign might result in a problem. For example, (?variablename =value)

Looking at Biju's answer I found a working solution.

I created an extra context-file test-context.xml:

<context:property-placeholder location="classpath:config/spring-test.properties"/>

Containing the profile:

spring.profiles.active=localtest

And loading the test with:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration(locations = {
    "classpath:config/test-context.xml" })
public class TestContext {

  @Test
  public void testContext(){

  }
}

This saves some work when creating multiple test-cases.

On Linux there is also a very neat tool that can tell right away what each error code means. On Ubuntu: apt-get install errno.

Then if for example you want to get the description of error type 2, just type errno 2 in the terminal.

With errno -l you get a list with all errors and their descriptions. Much easier that other methods mentioned by previous posters.

Adding false after function will stop event propagation

<a (click)="foo(); false">click with stop propagation</a>

More of an alternate solution, but all modern browsers send the domain cookies along with the connection, so using:

var authToken = 'R3YKZFKBVi';

document.cookie = 'X-Authorization=' + authToken + '; path=/';

var ws = new WebSocket(
    'wss://localhost:9000/wss/'
);

End up with the request connection headers:

Cookie: X-Authorization=R3YKZFKBVi

The line onclick = writeLED(1,1) means that you want to immediately execute the function writeLED(arg1, arg2) with arguments 1, 1 and assign the return value; you need to instead create a function that will execute with those arguments and assign that. The topmost answer gave one example - another is to use the bind() function like so:

    var writeLEDWithSpecifiedArguments = writeLED.bind(this, 1,1);
    document.getElementById('buttonLED'+id).onclick = writeLEDWithSpecifiedArguments;

Solved using JavaScript + jQuery! I just need similar solution to my project but current solution with HTML and CSS is not ok for me because there is issue with column height + I need more then one column to be fixed. So I create simple javascript solution using jQuery

You can try it here https://jsfiddle.net/kindrosker/ffwqvntj/

All you need is setup home many columsn will be fixed in data-count-fixed-columns parameter

<table class="table" data-count-fixed-columns="2" cellpadding="0" cellspacing="0">

and run js function

app_handle_listing_horisontal_scroll($('#table-listing'))

Use this

SELECT * 
FROM TableToSearch 
WHERE NOT REGEXP_LIKE(ColumnToSearch, '^-?[0-9]+(\.[0-9]+)?$');

This three function are the same.

$(document).ready(function(){

}) 

and

$(function(){

}); 

and

jQuery(document).ready(function(){

});

here $ is used for define jQuery like $ = jQuery.

Now difference is that

$(document).ready is jQuery event that is fired when DOM is loaded, so it’s fired when the document structure is ready.

$(window).load event is fired after whole content is loaded like page contain images,css etc.

When you double-quote a path, you're stopping the tilde expansion. So there are a few ways to do this:

cd ~/"My Code"
cd ~/'My Code'

The tilde is not quoted here, so tilde expansion will still be run.

cd "$HOME/My Code"

You can expand environment variables inside double-quoted strings; this is basically what the tilde expansion is doing

cd ~/My\ Code

You can also escape special characters (such as space) with a backslash.

It would be more helpful if you posed a more complete working (or in this case non-working) example.

I tried the following:

import numpy as np
import matplotlib.pyplot as plt

x = np.random.randn(1000)

fig = plt.figure()
ax = fig.add_subplot(111)
n, bins, rectangles = ax.hist(x, 50, density=True)
fig.canvas.draw()
plt.show()

This will indeed produce a bar-chart histogram with a y-axis that goes from [0,1].

Further, as per the hist documentation (i.e. ax.hist? from ipython), I think the sum is fine too:

*normed*:
If *True*, the first element of the return tuple will
be the counts normalized to form a probability density, i.e.,
``n/(len(x)*dbin)``.  In a probability density, the integral of
the histogram should be 1; you can verify that with a
trapezoidal integration of the probability density function::

    pdf, bins, patches = ax.hist(...)
    print np.sum(pdf * np.diff(bins))

Giving this a try after the commands above:

np.sum(n * np.diff(bins))

I get a return value of 1.0 as expected. Remember that normed=True doesn't mean that the sum of the value at each bar will be unity, but rather than the integral over the bars is unity. In my case np.sum(n) returned approx 7.2767.
