Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

you can use raiserror. Read more details here

--from MSDN

BEGIN TRY
    -- RAISERROR with severity 11-19 will cause execution to 
    -- jump to the CATCH block.

EDIT If you are using SQL Server 2012+ you can use throw clause. Here are the details.

As Pablo said, you need to use find instead of grep, but there's no need to pipe find to grep. find has that functionality built in:

find . -regex 'f[[:alnum:]]\.frm'

find is a very powerful program for searching for files by name and supports searching by file type, depth limiting, combining different search terms with boolean operations, and executing arbitrary commands on found files. See the find man page for more information.

int.MaxValue = 2147483647
2055786000 + 93552000 = 2149338000 > int.MaxValue

So you cannot store this number into an integer. You could use Int64 type which has a maximum value of 9,223,372,036,854,775,807.

1. Constant pointer: A constant pointer can point only to a single variable of the respective data type during the entire program.we can change the value of the variable pointed by the pointer. Initialization should be done during the time of declaration itself.

Syntax:

datatype *const var;

char *const comes under this case.

/*program to illustrate the behaviour of constant pointer */

#include<stdio.h>
int main(){
  int a=10;
  int *const ptr=&a;
  *ptr=100;/* we can change the value of object but we cannot point it to another variable.suppose another variable int b=20; and ptr=&b; gives you error*/
  printf("%d",*ptr);
  return 0;
}

2. Pointer to a const value: In this a pointer can point any number of variables of the respective type but we cannot change the value of the object pointed by the pointer at that specific time.

Syntax:

const datatype *varor datatype const *var

const char* comes under this case.

/* program to illustrate the behavior of pointer to a constant*/

   #include<stdio.h>
   int main(){
       int a=10,b=20;
       int const *ptr=&a;
       printf("%d\n",*ptr);
       /*  *ptr=100 is not possible i.e we cannot change the value of the object pointed by the pointer*/
       ptr=&b;
       printf("%d",*ptr);
       /*we can point it to another object*/
       return 0;
    }

If you have an array, then you can find the number of elements in the array by dividing the size of the array in bytes by the size of each element in bytes:

char x[10];
int elements_in_x = sizeof(x) / sizeof(x[0]);

For the specific case of char, since sizeof(char) == 1, sizeof(x) will yield the same result.

If you only have a pointer to an array, then there's no way to find the number of elements in the pointed-to array. You have to keep track of that yourself. For example, given:

char x[10];
char* pointer_to_x = x;

there is no way to tell from just pointer_to_x that it points to an array of 10 elements. You have to keep track of that information yourself.

There are numerous ways to do that: you can either store the number of elements in a variable or you can encode the contents of the array such that you can get its size somehow by analyzing its contents (this is effectively what null-terminated strings do: they place a '\0' character at the end of the string so that you know when the string ends).

And another expansion:

# create dummy matrix
set.seed(10)
m <- matrix(round(runif(25, 1, 5)), 5)
d <- as.data.frame(m)

If you want to assign new column names you can do following on data.frame:

# an identical effect can be achieved with colnames()   
names(d) <- LETTERS[1:5]
> d
  A B C D E
1 3 2 4 3 4
2 2 2 3 1 3
3 3 2 1 2 4
4 4 3 3 3 2
5 1 3 2 4 3

If you, however run previous command on matrix, you'll mess things up:

names(m) <- LETTERS[1:5]
> m
     [,1] [,2] [,3] [,4] [,5]
[1,]    3    2    4    3    4
[2,]    2    2    3    1    3
[3,]    3    2    1    2    4
[4,]    4    3    3    3    2
[5,]    1    3    2    4    3
attr(,"names")
 [1] "A" "B" "C" "D" "E" NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA  NA 
[20] NA  NA  NA  NA  NA  NA 

Since matrix can be regarded as two-dimensional vector, you'll assign names only to first five values (you don't want to do that, do you?). In this case, you should stick with colnames().

So there...

Yes there is a difference in the performance of both: jQuery('#id').show() is slower than jQuery('#id').css("display","block") as in former case extra work is to be done for retrieving the initial state from the jquery cache as display is not a binary attribute it can be inline,block,none,table, etc. similar is the case with hide() method.

See: http://jsperf.com/show-vs-addclass

File myFile = new File(uri.toString());
myFile.getAbsolutePath()

should return u the correct path

EDIT

As @Tron suggested the working code is

File myFile = new File(uri.getPath());
myFile.getAbsolutePath()

Jenkins stores the console log on master. If you want programmatic access to the log, and you are running on master, you can access the log that Jenkins already has, without copying it to the artifacts or having to GET the http job URL.

From http://javadoc.jenkins.io/archive/jenkins-1.651/hudson/model/Run.html#getLogFile(), this returns the File object for the console output (in the jenkins file system, this is the "log" file in the build output directory).

In my case, we use a chained (child) job to do parsing and analysis on a parent job's build.

When using a groovy script run in Jenkins, you get an object named "build" for the run. We use this to get the http://javadoc.jenkins.io/archive/jenkins-1.651/hudson/model/Build.html for the upstream job, then call this job's .getLogFile().

Added bonus; since it's just a File object, we call .getParent() to get the folder where Jenkins stores build collateral (like test xmls, environment variables, and other things that may not be explicitly exposed through the artifacts) which we can also parse.

Double added bonus; we also use matrix jobs. This sometimes makes inferring the file path on the system a pain. .getLogFile().getParent() takes away all the pain.

The following is inspired by Simon's answer. It's self-contained (doesn't require a separate format file), which makes it great for inclusion into .bashrc.

curl_time() {
    curl -so /dev/null -w "\
   namelookup:  %{time_namelookup}s\n\
      connect:  %{time_connect}s\n\
   appconnect:  %{time_appconnect}s\n\
  pretransfer:  %{time_pretransfer}s\n\
     redirect:  %{time_redirect}s\n\
starttransfer:  %{time_starttransfer}s\n\
-------------------------\n\
        total:  %{time_total}s\n" "$@"
}

Futhermore, it should work with all arguments that curl normally takes, since the "$@" just passes them through. For example, you can do:

curl_time -X POST -H "Content-Type: application/json" -d '{"key": "val"}' https://postman-echo.com/post

Output:

   namelookup:  0,125000s
      connect:  0,250000s
   appconnect:  0,609000s
  pretransfer:  0,609000s
     redirect:  0,000000s
starttransfer:  0,719000s
-------------------------
        total:  0,719000s

Here is a solution based on a "function" which processes each character until it finds the delimiter character.

It is relatively slow, but it is at least not a brain teaser (except for the function part).

:: Example #1:
set data=aa bb cc
echo Splitting off from "%data%":
call :split_once "%data%" " " "left" "right"
echo Split off: %left%
echo Remaining: %right%
echo.

:: Example #2:
echo List of paths in PATH env var:
set paths=%PATH%
:loop
    call :split_once "%paths%" ";" "left" "paths"
    if "%left%" equ "" goto loop_end
    echo %left%
goto loop
:loop_end



:: HERE BE FUNCTIONS
goto :eof

:: USAGE:
::   call :split_once "string to split once" "delimiter_char" "left_var" "right_var"
:split_once
    setlocal
    set right=%~1
    set delimiter_char=%~2
    set left=

    if "%right%" equ "" goto split_once_done

    :split_once_loop
        if "%right:~0,1%" equ "%delimiter_char%" set right=%right:~1%&& goto split_once_done
        if "%right:~0,1%" neq "%delimiter_char%" set left=%left%%right:~0,1%
        if "%right:~0,1%" neq "%delimiter_char%" set right=%right:~1%
        if "%right%" equ "" goto split_once_done
    goto split_once_loop

    :split_once_done
    endlocal & set %~3=%left%& set %~4=%right%
goto:eof

There is a way to create war file of your project from eclipse.

First a create an xml file with the following code,

Replace HistoryCheck with your project name.

<?xml version="1.0" encoding="UTF-8"?>
<project name="HistoryCheck" basedir="." default="default">
    <target name="default" depends="buildwar,deploy"></target>
    <target name="buildwar">
        <war basedir="war" destfile="HistoryCheck.war" webxml="war/WEB-INF/web.xml">
            <exclude name="WEB-INF/**" />
            <webinf dir="war/WEB-INF/">
                <include name="**/*.jar" />
            </webinf>
        </war>
    </target>
    <target name="deploy">
        <copy file="HistoryCheck.war" todir="." />
    </target>
</project>

Now, In project explorer right click on that xml file and Run as-> ant build

You can see the war file of your project in your project folder.

I am not sure why anyone hasn't suggested http://gitblit.com. Pure java based solution, allow HTTP protocol and really easy to setup.

Yet another way to do this:

(Get-Date).AddDays(-1).Date.AddHours(22)

To print off_t:

printf("%jd\n", (intmax_t)x);

To print size_t:

printf("%zu\n", x);

To print ssize_t:

printf("%zd\n", x);

See 7.19.6.1/7 in the C99 standard, or the more convenient POSIX documentation of formatting codes:

http://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html

If your implementation doesn't support those formatting codes (for example because you're on C89), then you have a bit of a problem since AFAIK there aren't integer types in C89 that have formatting codes and are guaranteed to be as big as these types. So you need to do something implementation-specific.

For example if your compiler has long long and your standard library supports %lld, you can confidently expect that will serve in place of intmax_t. But if it doesn't, you'll have to fall back to long, which would fail on some other implementations because it's too small.

None of solutions on this page works correctly and universally for all levels and long (wrapped) paragraphs. It’s really tricky to achieve a consistent indentation due to variable size of marker (1., 1.2, 1.10, 1.10.5, …); it can’t be just “faked,” not even with a precomputed margin/padding for each possible indentation level.

I finally figured out a solution that actually works and doesn’t need any JavaScript.

It’s tested on Firefox 32, Chromium 37, IE 9 and Android Browser. Doesn't work on IE 7 and previous.

CSS:

ol {
  list-style-type: none;
  counter-reset: item;
  margin: 0;
  padding: 0;
}

ol > li {
  display: table;
  counter-increment: item;
  margin-bottom: 0.6em;
}

ol > li:before {
  content: counters(item, ".") ". ";
  display: table-cell;
  padding-right: 0.6em;    
}

li ol > li {
  margin: 0;
}

li ol > li:before {
  content: counters(item, ".") " ";
}

Example:

Try it on JSFiddle, fork it on Gist.

Another cause (verified):

1. Apple has a major bug in Xcode going back to version 3.x, where it magically overwrites the OS X keychain with a fake keychain from inside Xcode, re-installing certs (and private keys!) that you already deleted

2. ...so, if you have "new cert" installed, and nothing else, Xcode will sometimes get into an infinite loop where it will keep ALSO installing "old cert" (that doesn't exist anywhere except inside XCode!).

3. ...and because of ANOTHER bug in Xcode (unfixed for 3+ years now...), Xcode sometimes automatically selects the "oldest cert I can find" (whcih, by definition, is incorrect - I think someone at Apple got mixed up between "oldest" and "newest" :( )

4. ...and EVEN THOUGH you've selected the correct provisioning profile, Xcode sends the "old" provisioning profile to the device, then signs with the "new" profile, causing this error

Solution: you have to un-FUBAR Xcode's FUBAR of your Keychain.

This is harder than it sounds (there are multiple SO posts on this topic) - it involves multiple reboots of your machine, deleting the key every time.

Eventually, Xcode gives up on corrupting your OS, and accepts the reality you present it with :).

You can either do this on a PHP level or on a Javascript level. If you use Javascript, and/or JQuery, you can check and validate if all the checkboxes are checked with a selector...

Jquery also offers several validation libraries. Check out: http://jqueryvalidation.org/

The problem with using Javascript to validate is that it may be bypassed so it is wise to check on the server too.

Example using PHP and assuming you are calling a PO

<?php
    if( $_GET["BoxSelect"] )
 {
     //Process your form here
     // Save to database, send email, redirect...
} else {

     // Return an error and do not anything
     echo "Checkbox is missing"; 


     exit();
 }
?>

A few wrinkles that I don't see being addressed in other answers:

1. the element can contain multiple levels of child nodes (e.g. child nodes that have child nodes that have child nodes...)
2. a selection can consist of different start and end positions (e.g. multiple chars are selected)
3. the node containing a Caret start/end may not be either the element or its direct children

Here's a way to get start and end positions as offsets to the element's textContent value:

// node_walk: walk the element tree, stop when func(node) returns false
function node_walk(node, func) {
  var result = func(node);
  for(node = node.firstChild; result !== false && node; node = node.nextSibling)
    result = node_walk(node, func);
  return result;
};

// getCaretPosition: return [start, end] as offsets to elem.textContent that
//   correspond to the selected portion of text
//   (if start == end, caret is at given position and no text is selected)
function getCaretPosition(elem) {
  var sel = window.getSelection();
  var cum_length = [0, 0];

  if(sel.anchorNode == elem)
    cum_length = [sel.anchorOffset, sel.extentOffset];
  else {
    var nodes_to_find = [sel.anchorNode, sel.extentNode];
    if(!elem.contains(sel.anchorNode) || !elem.contains(sel.extentNode))
      return undefined;
    else {
      var found = [0,0];
      var i;
      node_walk(elem, function(node) {
        for(i = 0; i < 2; i++) {
          if(node == nodes_to_find[i]) {
            found[i] = true;
            if(found[i == 0 ? 1 : 0])
              return false; // all done
          }
        }

        if(node.textContent && !node.firstChild) {
          for(i = 0; i < 2; i++) {
            if(!found[i])
              cum_length[i] += node.textContent.length;
          }
        }
      });
      cum_length[0] += sel.anchorOffset;
      cum_length[1] += sel.extentOffset;
    }
  }
  if(cum_length[0] <= cum_length[1])
    return cum_length;
  return [cum_length[1], cum_length[0]];
}

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

The operators delete and delete [] are used respectively to destroy the objects created with new and new[], returning to the allocated memory left available to the compiler's memory manager.

Objects created with new must necessarily be destroyed with delete, and that the arrays created with new[] should be deleted with delete[].

jAndy's solution is probably best, but if you can't rely on filter you could do something like:

var myArray = [
    {field: 'id', operator: 'eq', value: 'id'}, 
    {field: 'cStatus', operator: 'eq', value: 'cStatus'}, 
    {field: 'money', operator: 'eq', value: "money"}
];

myArray.remove_key = function(key){
    var i = 0, 
        keyval = null;
    for( ; i < this.length; i++){
        if(this[i].field == key){
            keyval = this.splice(i, 1);
            break;
        }
    }
    return keyval;
}

For setting the PATH on Yosemite (OS X 10.10.5), use the command below:

echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bash_profile

To reload either quit terminal and start up again or use:

source ~/.bash_profile

Helped me, hope it helps someone else out there!

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

In my case, in the initializer from the class I was using in the database's table, I wasn't setting any default value to my DateTime property, therefore resulting in the problem explained in @Andrew Orsich' answer. So I just made the property nullable. Or I could also have given it DateTime.Now in the constructor. Hope it helps someone.

To me, this is the biggest mistake in Sublime. Alt+F3 is hard to reach/remember, and Ctrl+Shift+G makes no sense considering Ctrl+D is "add next instance to selection".

Add this to your User Key Bindings (Preferences > Key Bindings):

{ "keys": ["ctrl+shift+d"], "command": "find_all_under" },

Now you can highlight something, press Ctrl+Shift+D, and it will add every other instance in the file to the selection.

If you want to change the permissions of an existing file, use chmod (change mode):

$itWorked = chmod ("/yourdir/yourfile", 0777);

If you want all new files to have certain permissions, you need to look into setting your umode. This is a process setting that applies a default modification to standard modes.

It is a subtractive one. By that, I mean a umode of 022 will give you a default permission of 755 (777 - 022 = 755).

But you should think very carefully about both these options. Files created with that mode will be totally unprotected from changes.

Adapting this to MySQL -- there is no FROM clause in UPDATE, but this works:

UPDATE
    item_master im
    JOIN
    group_master gm ON im.sku=gm.sku 
    JOIN
    Manufacturer_Master mm ON gm.ManufacturerID=mm.ManufacturerID
SET
    im.mf_item_number = gm.SKU --etc
WHERE
    im.mf_item_number like 'STA%'
    AND
    gm.manufacturerID=34

At finally OAuth gives you back the access token to access the resource from resource server, OpenID gives you back meta data details about resources in JWT / encrypted token

An optimized approach:

for (char character = *string; character != '\0'; character = *++string)
{
    putchar(character); // Do something with character.
}

Most C strings are null-terminated, meaning that as soon as the character becomes a '\0' the loop should stop. The *++string is moving the pointer one byte, then dereferencing it, and the loop repeats.

The reason why this is more efficient than strlen() is because strlen already loops through the string to find the length, so you would effectively be looping twice (one more time than needed) with strlen().

From MySQL documentation:

The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used. For example, utf8 characters can require up to three bytes per character, so a VARCHAR column that uses the utf8 character set can be declared to be a maximum of 21,844 characters.

Limits for the VARCHAR varies depending on charset used. Using ASCII would use 1 byte per character. Meaning you could store 65,535 characters. Using utf8 will use 3 bytes per character resulting in character limit of 21,844. BUT if you are using the modern multibyte charset utf8mb4 which you should use! It supports emojis and other special characters. It will be using 4 bytes per character. This will limit the number of characters per table to 16,383. Note that other fields such as INT will also be counted to these limits.

Conclusion:

utf8 maximum of 21,844 characters

utf8mb4 maximum of 16,383 characters

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

There is a great library to make your life easier Dapper.Contrib.Extensions. After including this you can just write:

public int Add(Transaction transaction)
{
        using (IDbConnection db = Connection)
        {
                return (int)db.Insert(transaction);
        }
}

Edit: Don't miss Stefan's solution above, which uses the very handy http_build_query() function: https://stackoverflow.com/a/1764199/179125

knittl is right on about escaping. However, there's a simpler way to do this:

$url = 'http://example.com/index.php?';
$url .= 'aValues[]=' . implode('&aValues[]=', array_map('urlencode', $aValues));

If you want to do this with an associative array, try this instead:

PHP 5.3+ (lambda function)

$url = 'http://example.com/index.php?';
$url .= implode('&', array_map(function($key, $val) {
    return 'aValues[' . urlencode($key) . ']=' . urlencode($val);
  },
  array_keys($aValues), $aValues)
);

PHP <5.3 (callback)

function urlify($key, $val) {
  return 'aValues[' . urlencode($key) . ']=' . urlencode($val);
}

$url = 'http://example.com/index.php?';
$url .= implode('&', array_map('urlify', array_keys($aValues), $aValues));

Funny Easter Egg.
In Ubuntu version of Chrome, in Task Manager (shift+esc), with right-click you can add a sci-fi column that in italian version is "Capre Teletrasportate" (Teleported Goats).

A funny theory about it is here.

This error is usually encountered when inserting a record in a table where one of the columns is a VARCHAR or CHAR data type and the length of the value being inserted is longer than the length of the column.

I am not satisfied how Microsoft decided to inform with this "dry" response message, without any point of where to look for the answer.

If you want your container to have it's own virtual ethernet socket (with it's own MAC address), iptables, then use the Macvlan driver. This may be necessary to route traffic out to your/ISPs router.

You could try turning off the main Activity's ability to save its state (thus making it forget what control had text and what had focus). You will need to have some other way of remembering what your EditText's have and repopulating them onResume(). Launch your sub-Activities with startActivityForResult() and create an onActivityResult() handler in your main Activity that will update the EditText's correctly. This way you can set the proper button you want focused onResume() at the same time you repopulate the EditText's by using a myButton.post(new Runnable(){ run() { myButton.requestFocus(); } });

The View.post() method is useful for setting focus initially because that runnable will be executed after the window is created and things settle down, allowing the focus mechanism to function properly by that time. Trying to set focus during onCreate/Start/Resume() usually has issues, I've found.

Please note this is pseudo-code and non-tested, but it's a possible direction you could try.

This is because according to CSS 2.1, the effect of position: relative on table elements is undefined. Illustrative of this, position: relative has the desired effect on Chrome 13, but not on Firefox 4. Your solution here is to add a div around your content and put the position: relative on that div instead of the td. The following illustrates the results you get with the position: relative (1) on a div good), (2) on a td(no good), and finally (3) on a div inside a td (good again).

<table>_x000D_
  <tr>_x000D_
    <td>_x000D_
      <div style="position:relative;">_x000D_
        <span style="position:absolute; left:150px;">_x000D_
          Absolute span_x000D_
        </span>_x000D_
        Relative div_x000D_
      </div>_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

Now there is special method - get_fields()

    >>> from django.contrib.auth.models import User
    >>> User._meta.get_fields()

It accepts two parameters that can be used to control which fields are returned:

• include_parents

  True by default. Recursively includes fields defined on parent classes. If set to False, get_fields() will only search for fields declared directly on the current model. Fields from models that directly inherit from abstract models or proxy classes are considered to be local, not on the parent.

• include_hidden

  False by default. If set to True, get_fields() will include fields that are used to back other field’s functionality. This will also include any fields that have a related_name (such as ManyToManyField, or ForeignKey) that start with a “+”

By default, there is not any proper answer to disable saving a password in your browser. But luckily there is a way around and it works in almost all the browsers.

To achieve this, add a dummy input just before the actual input with autocomplete="off" and some custom styling to hide it and providing tabIndex.

Some browsers' (Chrome) autocomplete will fill in the first password input it finds, and the input before that, so with this trick it will only fill in an invisible input that doesn't matter.

          <div className="password-input">
            <input
              type="password"
              id="prevent_autofill"
              autoComplete="off"
              style={{
                opacity: '0',
                position: 'absolute',
                height: '0',
                width: '0',
                padding: '0',
                margin: '0'
              }}
              tabIndex="-2"
            />
            <input
              type="password"
              autoComplete="off"
              className="password-input-box"
              placeholder="Password"
              onChange={e => this.handleChange(e, 'password')}
            />
          </div>

In visual studio.

• Create or open a project.
• Right-click project from solution explorer.
• Select "Add service refernce"
• Paste the address with WSDL you received.
• Click OK.

If no errors, you should be able to see the service reference in the object browser and all related methods.

There was a bug, but it was fixed in the meantime. :host { } works fine now.

Also supported are

• :host(selector) { ... } for selector to match attributes, classes, ... on the host element

• :host-context(selector) { ... } for selector to match elements, classes, ...on parent components

• selector /deep/ selector (alias selector >>> selector doesn't work with SASS) for styles to match across element boundaries

  • UPDATE: SASS is deprecating /deep/.
    Angular (TS and Dart) added ::ng-deep as a replacement that's also compatible with SASS.

  • UPDATE2: ::slotted ::slotted is now supported by all new browsers and can be used with `ViewEncapsulation.ShadowDom
    https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted

See also Load external css style into Angular 2 Component

/deep/ and >>> are not affected by the same selector combinators that in Chrome which are deprecated.
Angular emulates (rewrites) them, and therefore doesn't depend on browsers supporting them.

This is also why /deep/ and >>> don't work with ViewEncapsulation.Native which enables native shadow DOM and depends on browser support.

for item in items:
   extant_set.add(item)

For the record, I think the assertion that "There should be one-- and preferably only one --obvious way to do it." is bogus. It makes an assumption that many technical minded people make, that everyone thinks alike. What is obvious to one person is not so obvious to another.

I would argue that my proposed solution is clearly readable, and does what you ask. I don't believe there are any performance hits involved with it--though I admit I might be missing something. But despite all of that, it might not be obvious and preferable to another developer.

break will stop the current loop (or pass an integer to tell it how many loops to break from).

continue will stop the current iteration and start the next one.

We can mock list properly for foreach loop. Please find below code snippet and explanation.

This is my actual class method where I want to create test case by mocking list. this.nameList is a list object.

public void setOptions(){
    // ....
    for (String str : this.nameList) {
        str = "-"+str;
    }
    // ....
}

The foreach loop internally works on iterator, so here we crated mock of iterator. Mockito framework has facility to return pair of values on particular method call by using Mockito.when().thenReturn(), i.e. on hasNext() we pass 1st true and on second call false, so that our loop will continue only two times. On next() we just return actual return value.

@Test
public void testSetOptions(){
    // ...
    Iterator<SampleFilter> itr = Mockito.mock(Iterator.class);
    Mockito.when(itr.hasNext()).thenReturn(true, false);
    Mockito.when(itr.next()).thenReturn(Mockito.any(String.class);  

    List mockNameList = Mockito.mock(List.class);
    Mockito.when(mockNameList.iterator()).thenReturn(itr);
    // ...
}

In this way we can avoid sending actual list to test by using mock of list.

Is there such a thing as destructors for ECMAScript 6?

No. EcmaScript 6 does not specify any garbage collection semantics at all^[1], so there is nothing like a "destruction" either.

If I register some of my object's methods as event listeners in the constructor, I want to remove them when my object is deleted

A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered.
What you are actually looking for is a method of registering listeners without marking them as live root objects. (Ask your local eventsource manufacturer for such a feature).

_{1): Well, there is a beginning with the specification of WeakMap and WeakSet objects. However, true weak references are still in the pipeline [1][2].}

You'll have to include/require the class anyway, otherwise PHP won't know about the namespace.
You don't necessary have to do it in the same file though. You can do it in a bootstrap file for example. (or use an autoloader, but that's not the topic actually)

echo "$string" | tr xyz _

would replace each occurrence of x, y, or z with _, giving A__BC___DEF__LMN in your example.

echo "$string" | sed -r 's/[xyz]+/_/g'

would replace repeating occurrences of x, y, or z with a single _, giving A_BC_DEF_LMN in your example.

Swift 4.2 or later

Range and partial range subscripting using String's indices property

As variation of @LeoDabus nice answer, we may add an additional extension to DefaultIndices with the purpose of allowing us to fall back on the indices property of String when implementing the custom subscripts (by Int specialized ranges and partial ranges) for the latter.

extension DefaultIndices {
    subscript(at: Int) -> Elements.Index { index(startIndex, offsetBy: at) }
}

// Moving the index(_:offsetBy:) to an extension yields slightly
// briefer implementations for these String extensions.
extension String {
    subscript(range: Range<Int>) -> SubSequence {
        let start = indices[range.lowerBound]
        return self[start..<indices[start...][range.count]]
    }
    subscript(range: ClosedRange<Int>) -> SubSequence {
        let start = indices[range.lowerBound]
        return self[start...indices[start...][range.count]]
    }
    subscript(range: PartialRangeFrom<Int>) -> SubSequence {
        self[indices[range.lowerBound]...]
    }
    subscript(range: PartialRangeThrough<Int>) -> SubSequence {
        self[...indices[range.upperBound]]
    }
    subscript(range: PartialRangeUpTo<Int>) -> SubSequence {
        self[..<indices[range.upperBound]]
    }
}

let str = "foo bar baz bax"
print(str[4..<6]) // "ba"
print(str[4...6]) // "bar"
print(str[4...])  // "bar baz bax"
print(str[...6])  // "foo bar"
print(str[..<6])  // "foo ba"

Thanks @LeoDabus for the pointing me in the direction of using the indices property as an(other) alternative to String subscripting!

Using the otherwise pointless ? : operator to initialise a const variable

const int bytesPerPixel = isAlpha() ? 4 : 3;

You need to follow the advice from Miles M comment and here is a little code that fixes the range in mysql. Also u need to open up my.ini(Mysql) and change max_execution_time=60 to max_execution_time=6000; for large databases. Dont use "ALTER TABLE tablename AUTO_INCREMENT = 1" it will delete everything in your database.

$con=mysqli_connect($dbhost, $dbuser, $dbpass, $database);
$res=mysqli_query($con, "select * FROM data WHERE id LIKE id ORDER BY id ASC");
$count = 0;  
while ($row = mysqli_fetch_array($res)){
         $count++;
        
    mysqli_query($con, "UPDATE data SET id='".$count."' WHERE id='".$row['id']."'");
    
         }
         echo 'Done reseting id';
         mysqli_close($con);

You should definitely have a look at this answer of mine:

• Extracting table contents from a collection of PDF files

and also have a look at all the links included therein.

Tabula/TabulaPDF is currently the best table extraction tool that is available for PDF scraping.

To redirect Without Query String add below lines in Server block under listen port line:

if ($uri ~ .*.containingString$) {
           return 301 https://$host/$uri/;
}

With Query String:

if ($uri ~ .*.containingString$) {
           return 301 https://$host/$uri/?$query_string;
}

Dan Benjamin's Hivelogic article Installing Ruby, RubyGems, and Rails on Snow Leopard is the recommended place to go although the article is for 1.8, so here's a Ruby 1.9-specific install on Snow Leopard. Watch out for the 64-bit thing... either go all 64-bit 'fat' (as is - for example - Apache on OS X, which can cause problems with 32-bit libraries) or check any gems you're likely to use to make sure they're okay for 64-bit.

You can modify the id without having to use getElementById

Example:

<div id = 'One' onclick = "One.id = 'Two'; return false;">One</div>

You can see it here: http://jsbin.com/elikaj/1/

Tested with Mozilla Firefox 22 and Google Chrome 60.0

I used the sdk.

eg:

using SevenZip.Compression.LZMA;
private static void CompressFileLZMA(string inFile, string outFile)
{
   SevenZip.Compression.LZMA.Encoder coder = new SevenZip.Compression.LZMA.Encoder();

   using (FileStream input = new FileStream(inFile, FileMode.Open))
   {
      using (FileStream output = new FileStream(outFile, FileMode.Create))
      {
          coder.Code(input, output, -1, -1, null);
          output.Flush();
      }
   }
}

new Date().toISOString().slice(0,10); 

would work too

There isn't a good way to do this in SQL. Some approaches I have seen:

1) Use CASE combined with boolean operators:

WHERE
    OrderNumber = CASE 
        WHEN (IsNumeric(@OrderNumber) = 1)
        THEN CONVERT(INT, @OrderNumber)
        ELSE -9999 -- Some numeric value that just cannot exist in the column
    END
    OR 
    FirstName LIKE CASE
        WHEN (IsNumeric(@OrderNumber) = 0)
        THEN '%' + @OrderNumber
        ELSE ''
    END

2) Use IF's outside the SELECT

IF (IsNumeric(@OrderNumber)) = 1
BEGIN
    SELECT * FROM Table
    WHERE @OrderNumber = OrderNumber
END ELSE BEGIN
    SELECT * FROM Table
    WHERE OrderNumber LIKE '%' + @OrderNumber
END

3) Using a long string, compose your SQL statement conditionally, and then use EXEC

The 3rd approach is hideous, but it's almost the only think that works if you have a number of variable conditions like that.

I like Alex FTPS Client which is written by a Microsoft MVP name Alex Pilotti. It's a C# library you can use in Console apps, Windows Forms, PowerShell, ASP.NET (in any .NET language). If you have a multithreaded app you will have to configure the library to run syncronously, but overall a good client that will most likely get you what you need.

If you have Spring in you classpath then the following will do it.

Find all classes in a package that are annotated with XmlRootElement:

private List<Class> findMyTypes(String basePackage) throws IOException, ClassNotFoundException
{
    ResourcePatternResolver resourcePatternResolver = new PathMatchingResourcePatternResolver();
    MetadataReaderFactory metadataReaderFactory = new CachingMetadataReaderFactory(resourcePatternResolver);

    List<Class> candidates = new ArrayList<Class>();
    String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX +
                               resolveBasePackage(basePackage) + "/" + "**/*.class";
    Resource[] resources = resourcePatternResolver.getResources(packageSearchPath);
    for (Resource resource : resources) {
        if (resource.isReadable()) {
            MetadataReader metadataReader = metadataReaderFactory.getMetadataReader(resource);
            if (isCandidate(metadataReader)) {
                candidates.add(Class.forName(metadataReader.getClassMetadata().getClassName()));
            }
        }
    }
    return candidates;
}

private String resolveBasePackage(String basePackage) {
    return ClassUtils.convertClassNameToResourcePath(SystemPropertyUtils.resolvePlaceholders(basePackage));
}

private boolean isCandidate(MetadataReader metadataReader) throws ClassNotFoundException
{
    try {
        Class c = Class.forName(metadataReader.getClassMetadata().getClassName());
        if (c.getAnnotation(XmlRootElement.class) != null) {
            return true;
        }
    }
    catch(Throwable e){
    }
    return false;
}

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

I suggest you read The Objective-C Programming Language. The part about messaging is specifically what you want here, but the whole thing will help you get started. After that, maybe try doing a few tutorials to get a feel for it before you jump into making your own apps.

In Kotlin:

 ivBall.setOnClickListener(View.OnClickListener {

            //Animate using XML
            // val rotateAnimation = AnimationUtils.loadAnimation(activity, R.anim.rotate_indefinitely)

            //OR using Code
            val rotateAnimation = RotateAnimation(
                    0f, 359f,
                    Animation.RELATIVE_TO_SELF, 0.5f,
                    Animation.RELATIVE_TO_SELF, 0.5f

            )
            rotateAnimation.duration = 300
            rotateAnimation.repeatCount = 2

            //Either way you can add Listener like this
            rotateAnimation.setAnimationListener(object : Animation.AnimationListener {

                override fun onAnimationStart(animation: Animation?) {
                }

                override fun onAnimationRepeat(animation: Animation?) {
                }

                override fun onAnimationEnd(animation: Animation?) {

                    val rand = Random()
                    val ballHit = rand.nextInt(50) + 1
                    Toast.makeText(context, "ballHit : " + ballHit, Toast.LENGTH_SHORT).show()
                }
            })

            ivBall.startAnimation(rotateAnimation)
        })

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

http://www.enterprisedb.com/products-services-training/products/postgres-enterprise-manager

Ninja edit disclaimer/notice: it seems that this user is affiliated with EnterpriseDB, as the linked Postgres Enterprise Manager website contains a video of one Dave Page.

There are several options.

The easiest is likely the exec plugin.

You can also generate a jar containing all the dependencies using the assembly plugin.

Lastly, you can generate a file with the classpath in it using the dependency:classpath goal.

Choose Open Transcript from the ... dropdown to the right of the vote up/down and share links.

This will open a Transcript scrolling div on the right side.

You can then use Copy. Note that you cannot use Select All but need to click the top line, then scroll to the bottom using the scroll thumb, and then shift-click on the last line.

Note that you can also search within this text using the normal web page search.

You might want to try this to get the stream i.e first get the url and then open it as stream.

URL url = getClass().getResource("/initialization/Lifepaths.txt"); 
InputStream strm = url.openStream(); 

I once had a similar question: Reading txt file from jar fails but reading image works

Check if it is null or not e.g

if(Session["mykey"] != null)
{
  // Session is not expired
}
else
{
  //Session is expired
}

Don't live fanatically with the conventions that SUN have med up, do whats feel right to you and your team.

For example this is how eclipse do it, breaking the convention. Try adding implements Serializable and eclipse will ask to generate this line for you.

Update: There were special cases that was excluded didn't know that. I however withholds to do what you and your team seems fit.

///

is the shortcut for getting the Method Description comment block. But make sure you have written the function name and signature before adding it. First write the Function name and signature.

Then above the function name just type ///

and you will get it automatically

Simple solution

setcookie("NAME", "VALUE", time()+3600, '/', EXAMPLE.COM);

Setcookie's 5th parameter determines the (sub)domains that the cookie is available to. Setting it to (EXAMPLE.COM) makes it available to any subdomain (eg: SUBDOMAIN.EXAMPLE.COM )

Reference: http://php.net/manual/en/function.setcookie.php

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

Here is example of using aggregation API. To complicate the case we're grouping by case-insensitive words from array property of the document.

db.articles.aggregate([
    {
        $match: {
            keywords: { $not: {$size: 0} }
        }
    },
    { $unwind: "$keywords" },
    {
        $group: {
            _id: {$toLower: '$keywords'},
            count: { $sum: 1 }
        }
    },
    {
        $match: {
            count: { $gte: 2 }
        }
    },
    { $sort : { count : -1} },
    { $limit : 100 }
]);

that give result such as

{ "_id" : "inflammation", "count" : 765 }
{ "_id" : "obesity", "count" : 641 }
{ "_id" : "epidemiology", "count" : 617 }
{ "_id" : "cancer", "count" : 604 }
{ "_id" : "breast cancer", "count" : 596 }
{ "_id" : "apoptosis", "count" : 570 }
{ "_id" : "children", "count" : 487 }
{ "_id" : "depression", "count" : 474 }
{ "_id" : "hiv", "count" : 468 }
{ "_id" : "prognosis", "count" : 428 }

This answer will be for swift dictionary w/ String keys. Like this one below.

let dict: [String: Int] = ["hey": 1, "yo": 2, "sup": 3, "hello": 4, "whassup": 5]

Here's the extension I'll use.

extension Dictionary {
  func allKeys() -> [String] {
    guard self.keys.first is String else {
      debugPrint("This function will not return other hashable types. (Only strings)")
      return []
    }
    return self.flatMap { (anEntry) -> String? in
                          guard let temp = anEntry.key as? String else { return nil }
                          return temp }
  }
}

And I'll get all the keys later using this.

let componentsArray = dict.allKeys()

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

And now it's passed to the proxy backend.

When I'm doing something like this I use the onKeyUp event.

<script type="text/javascript">
 function bar() {
      //do stuff
 }
<input type="text" name="foo" onKeyUp="return bar()" />

but if you don't want to use an HTML event you could try to use jQuerys .change() method

$('.target').change(function() {
   //do stuff
});

in this example, the input would have to have a class "target"

if you're going to have multiple text boxes that you want to have done the same thing when their text is changed and you need their data then you could do this:

$('.target').change(function(event) {
   //do stuff with the "event" object as the object that called the method
)};

that way you can use the same code, for multiple text boxes using the same class without having to rewrite any code.

The cross-platform getmac package will work for this, if you don't mind taking on a dependency. It works with Python 2.7+ and 3.4+. It will try many different methods until either getting a address or returning None.

from getmac import get_mac_address
eth_mac = get_mac_address(interface="eth0")
win_mac = get_mac_address(interface="Ethernet 3")
ip_mac = get_mac_address(ip="192.168.0.1")
ip6_mac = get_mac_address(ip6="::1")
host_mac = get_mac_address(hostname="localhost")
updated_mac = get_mac_address(ip="10.0.0.1", network_request=True)

Disclaimer: I am the author of the package.

Update (Jan 14 2019): the package now only supports Python 2.7+ and 3.4+. You can still use an older version of the package if you need to work with an older Python (2.5, 2.6, 3.2, 3.3).

SELECT REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(19), CONVERT(DATETIME, getdate(), 112), 126), '-', ''), 'T', ''), ':', '') 

Unless you plan to import huge .sql files, just read the entire file into memory, and run it as a query.

It's been a while since I've used PHP, so, pseudo code:

all_query = read_file("/my/file.sql")
con = mysql_connect("localhost")
con.mysql_select_db("mydb")
con.mysql_query(all_query)
con.close()

Unless the files are huge (say, over several megabytes), there's no reason to execute it line-at-a-time, or try and split it into multiple queries (by splitting using ;, which as I commented on cam8001's answer, will break if the query has semi-colons within strings)..

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

The internal set of single quotes in your code is killing the string. Whenever you hit a single quote it ends the string and continues processing. You'll want something like:

$thisstring = 'this string is long \' in needs escaped single quotes or nothing will run';

you can drop the Constraint which is restricting you. If the column has access to other table. suppose a view is accessing the column which you are altering then it wont let you alter the column unless you drop the view. and after making changes you can recreate the view.

A revelation: Some blank cells are not actually blank! As I will show cells can have spaces, newlines and true empty:

To find these cells quickly you can do a few things.

1. The =CODE(A1) formula will return a #VALUE! if the cell is truly empty, otherwise a number will return. This number is the ASCII number used in =CHAR(32).
2. If you select the cell and click in the formula bar and use the cursor to select all.

Removing these:

If you only have a space in the cells these can be removed easily using:

1. Press ctrl + h to open find and replace.
2. Enter one space in the find what, leave replace with empty and ensure you have match entire cell contents is ticked in the options.
3. Press replace all.

If you have newlines this is more difficult and requires VBA:

1. Right click on the sheet tab > view code.

2. Then enter the following code. Remember the Chr(10) is a newline only replace this as required, e.g. " " & Char(10) is a space and a newline:

   Sub find_newlines()
       With Me.Cells
           Set c = .Find(Chr(10), LookIn:=xlValues, LookAt:=xlWhole)
           If Not c Is Nothing Then
               firstAddress = c.Address
               Do
                   c.Value = ""
                   Set c = .FindNext(c)
                   If c Is Nothing Then Exit Do
               Loop While c.Address <> firstAddress
           End If
       End With
   End Sub
   

3. Now run your code pressing F5.

After file supplied: Select the range of interest for improved performance, then run the following:

Sub find_newlines()
    With Selection
        Set c = .Find("", LookIn:=xlValues, LookAt:=xlWhole)
        If Not c Is Nothing Then
            firstAddress = c.Address
            Do
                c.Value = ""
                Set c = .FindNext(c)
                If c Is Nothing Then Exit Do
            Loop While c.Address <> firstAddress
        End If
    End With
End Sub

You can do

display/i $pc

and every time GDB stops, it will display the disassembly of the next instruction.

GDB-7.0 also supports set disassemble-next-line on, which will disassemble the entire next line, and give you more of the disassembly context.

You can always use System.Resources.ResourceManager which returns the cached ResourceManager used by this class. Since chan1 and chan2 represent two different images, you may use System.Resources.ResourceManager.GetObject(string name) which returns an object matching your input with the project resources

Example

object O = Resources.ResourceManager.GetObject("chan1"); //Return an object from the image chan1.png in the project
channelPic.Image = (Image)O; //Set the Image property of channelPic to the returned object as Image

Notice: Resources.ResourceManager.GetObject(string name) may return null if the string specified was not found in the project resources.

Thanks,
I hope you find this helpful :)

Sometimes we need to get the date from a string. One example with grouping:

record = '1518-09-06 00:57 some-alphanumeric-charecter'
pattern_date_time = ([0-9]{4}-[0-9]{2}-[0-9]{2} [0-9]{2}:[0-9]{2}) .+
match = re.match(pattern_date_time, record)
if match is not None:
  group = match.group()
  date = group[0]
  print(date) // outputs 1518-09-06 00:57

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

You will have to save the relationship on the server side. The value is the only part that is transmitted when the form is posted. You could do something nasty like...

<option value="2|Dog">Dog</option>

Then split the result apart if you really wanted to, but that is an ugly hack and a waste of bandwidth assuming the numbers are truly unique and have a one to one relationship with the text.

The best way would be to create an array, and loop over the array to create the HTML. Once the form is posted you can use the value to look up the text in that same array.

• @PathVariable is to obtain some placeholder from the URI (Spring call it an URI Template) — see Spring Reference Chapter 16.3.2.2 URI Template Patterns
• @RequestParam is to obtain a parameter from the URI as well — see Spring Reference Chapter 16.3.3.3 Binding request parameters to method parameters with @RequestParam

If the URL http://localhost:8080/MyApp/user/1234/invoices?date=12-05-2013 gets the invoices for user 1234 on December 5th, 2013, the controller method would look like:

@RequestMapping(value="/user/{userId}/invoices", method = RequestMethod.GET)
public List<Invoice> listUsersInvoices(
            @PathVariable("userId") int user,
            @RequestParam(value = "date", required = false) Date dateOrNull) {
  ...
}

Also, request parameters can be optional, and as of Spring 4.3.3 path variables can be optional as well. Beware though, this might change the URL path hierarchy and introduce request mapping conflicts. For example, would /user/invoices provide the invoices for user null or details about a user with ID "invoices"?

You can use a zip function with a list comprehension :

with open('ex.txt') as f:
    print zip(*[line.split() for line in f])[1]

result :

('10', '20', '30', '40', '23', '13')

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

Just call the method pack() after setting the ContentPane, (java 1.7, maybe older) like this:

JFrame frame = new JFrame();  
JPanel panel1 = new JPanel(); 
JPanel panel2 = new JPanel(); 
....
frame.setContentPane(panel1);
frame.pack();
...

frame.setContentPane(panel2);
frame.pack();
...

In a simular issue I had the desired dependency declared with scope provided. With this approach the transitive dependencies are fetched but are NOT included in the package phase, which is what you want. I also like this solution in terms of maintenance, because there is no pom, or custom pom as in whaley's solution, needed to maintain; you only need to provide the specific dependency in the container and be done

Rather than relying on key codes, which can be quite cumbersome, you can instead use regular expressions. By changing the pattern we can easily restrict the input to fit our needs. Note that this works with the keypress event and will allow the use of backspace (as in the accepted answer). It will not prevent users from pasting 'illegal' chars.

function testInput(event) {_x000D_
   var value = String.fromCharCode(event.which);_x000D_
   var pattern = new RegExp(/[a-zåäö ]/i);_x000D_
   return pattern.test(value);_x000D_
}_x000D_
_x000D_
$('#my-field').bind('keypress', testInput);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<label>_x000D_
   Test input:_x000D_
   <input id="my-field" type="text">_x000D_
</label>

It turns out the original poster's server (blueHost) has a FAQ concerning this very question.

Article 206.

This is because our servers require you (or your script) to use a properly formatted, valid From: field in the email's header. If the From: field is not formatted correctly, empty or the email address does not exist in the cPanel, the From: address will be changed to username@box###.bluehost.com.

You must change the script you are using to correctly use a valid From: header.

Examples of headers that should work would be:

From: [email protected]
From: "user" <[email protected]>

Examples of headers that will NOT work:

From: "[email protected]"
From: user @ domain.com
From: [email protected] <[email protected]>

Our servers will not accept the name for the email address and the email address to be the same. It will not accept a double declaration of the email address.

For scripts such as Joomla and Wordpress, you will need to follow their documentation for formatting the from fields properly. Wordpress will require the Mail From plugin.

Note: The email address you use must be a valid created account in the cPanel.

Definitely integers.

And even though BigDecimal technically exists 1.5 will still give you a pure Float in Ruby.

DO it like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");

Do not forget the % at the end

HTML

<form id="some_form">
<!-- some form elements -->
</form>

and jquery

$("#some_form").reset();

Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). If you have normal distribution with mean and std (which is sqr(var)) and you want to calculate:

from scipy.stats import norm

# cdf(x < val)
print norm.cdf(val, m, s)

# cdf(x > val)
print 1 - norm.cdf(val, m, s)

# cdf(v1 < x < v2)
print norm.cdf(v2, m, s) - norm.cdf(v1, m, s)

Read more about cdf here and scipy implementation of normal distribution with many formulas here.

You can set the spring profile by supplying -Dspring.profiles.active=<env>

For java files in source(src) directory, you can use by System.getProperty("spring.profiles.active")

For java files in test directory you can supply

• SPRING_PROFILES_ACTIVE to <env>

OR

Since, "environment", "jvmArgs" and "systemProperties" are ignored for the "test" task. In root build.gradle add a task to set jvm property and environment variable.

test {
    def profile = System.properties["spring.profiles.active"]
    systemProperty "spring.profiles.active",profile
    environment "SPRING.PROFILES_ACTIVE", profile
    println "Running ${project} tests with profile: ${profile}"
}

There's no built-in method for doing this in Python 2. If you need this, you need to write a prepend() method/function that operates on the OrderedDict internals with O(1) complexity.

For Python 3.2 and later, you should use the move_to_end method. The method accepts a last argument which indicates whether the element will be moved to the bottom (last=True) or the top (last=False) of the OrderedDict.

Finally, if you want a quick, dirty and slow solution, you can just create a new OrderedDict from scratch.

Details for the four different solutions:

Extend OrderedDict and add a new instance method

from collections import OrderedDict

class MyOrderedDict(OrderedDict):

    def prepend(self, key, value, dict_setitem=dict.__setitem__):

        root = self._OrderedDict__root
        first = root[1]

        if key in self:
            link = self._OrderedDict__map[key]
            link_prev, link_next, _ = link
            link_prev[1] = link_next
            link_next[0] = link_prev
            link[0] = root
            link[1] = first
            root[1] = first[0] = link
        else:
            root[1] = first[0] = self._OrderedDict__map[key] = [root, first, key]
            dict_setitem(self, key, value)

Demo:

>>> d = MyOrderedDict([('a', '1'), ('b', '2')])
>>> d
MyOrderedDict([('a', '1'), ('b', '2')])
>>> d.prepend('c', 100)
>>> d
MyOrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> d.prepend('a', d['a'])
>>> d
MyOrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> d.prepend('d', 200)
>>> d
MyOrderedDict([('d', 200), ('a', '1'), ('c', 100), ('b', '2')])

Standalone function that manipulates OrderedDict objects

This function does the same thing by accepting the dict object, key and value. I personally prefer the class:

from collections import OrderedDict

def ordered_dict_prepend(dct, key, value, dict_setitem=dict.__setitem__):
    root = dct._OrderedDict__root
    first = root[1]

    if key in dct:
        link = dct._OrderedDict__map[key]
        link_prev, link_next, _ = link
        link_prev[1] = link_next
        link_next[0] = link_prev
        link[0] = root
        link[1] = first
        root[1] = first[0] = link
    else:
        root[1] = first[0] = dct._OrderedDict__map[key] = [root, first, key]
        dict_setitem(dct, key, value)

Demo:

>>> d = OrderedDict([('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'c', 100)
>>> d
OrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'a', d['a'])
>>> d
OrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> ordered_dict_prepend(d, 'd', 500)
>>> d
OrderedDict([('d', 500), ('a', '1'), ('c', 100), ('b', '2')])

Use OrderedDict.move_to_end() (Python >= 3.2)

Python 3.2 introduced the OrderedDict.move_to_end() method. Using it, we can move an existing key to either end of the dictionary in O(1) time.

>>> d1 = OrderedDict([('a', '1'), ('b', '2')])
>>> d1.update({'c':'3'})
>>> d1.move_to_end('c', last=False)
>>> d1
OrderedDict([('c', '3'), ('a', '1'), ('b', '2')])

If we need to insert an element and move it to the top, all in one step, we can directly use it to create a prepend() wrapper (not presented here).

Create a new OrderedDict - slow!!!

If you don't want to do that and performance is not an issue then easiest way is to create a new dict:

from itertools import chain, ifilterfalse
from collections import OrderedDict


def unique_everseen(iterable, key=None):
    "List unique elements, preserving order. Remember all elements ever seen."
    # unique_everseen('AAAABBBCCDAABBB') --> A B C D
    # unique_everseen('ABBCcAD', str.lower) --> A B C D
    seen = set()
    seen_add = seen.add
    if key is None:
        for element in ifilterfalse(seen.__contains__, iterable):
            seen_add(element)
            yield element
    else:
        for element in iterable:
            k = key(element)
            if k not in seen:
                seen_add(k)
                yield element

d1 = OrderedDict([('a', '1'), ('b', '2'),('c', 4)])
d2 = OrderedDict([('c', 3), ('e', 5)])   #dict containing items to be added at the front
new_dic = OrderedDict((k, d2.get(k, d1.get(k))) for k in \
                                           unique_everseen(chain(d2, d1)))
print new_dic

output:

OrderedDict([('c', 3), ('e', 5), ('a', '1'), ('b', '2')])

Ok, in 2021, with a <project>/src/index.ts file, the following worked for me:

If VS Code complains with No inputs were found in config file... then change the include to…

"include": ["./src/**/*.ts"]

Found the above as a comment of How to Write Node.js Applications in Typescript

There is a DateTime constructor that takes a long.

DateTime today = new DateTime(t); // where t represents long format of dateTime 

In Powershell 3.0 and above there is both a Invoke-WebRequest and Invoke-RestMethod. Curl is actually an alias of Invoke-WebRequest in PoSH. I think using native Powershell would be much more appropriate than curl, but it's up to you :).

Invoke-WebRequest MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849901.aspx?f=255&MSPPError=-2147217396

Invoke-RestMethod MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849971.aspx?f=255&MSPPError=-2147217396

My vote would be for BBedit's free little brother TextWrangler.

The process manager + task scheduler approach I posted a year ago works well with some one-off service installations. But recently I started to design system in a micro-service fashion, with many small services talking to each other via IPC. So manually configuring each service has become unbearable.

Towards the goal of installing services without manual configuration, I created serman, a command line tool (install with npm i -g serman) to install an executable as a service. All you need to write (and only write once) is a simple service configuration file along with your executable. Run

serman install <path_to_config_file>

will install the service. stdout and stderr are all logged. For more info, take a look at the project website.

A working configuration file is very simple, as demonstrated below. But it also has many useful features such as <env> and <persistent_env> below.

<service>
  <id>hello</id>
  <name>hello</name>
  <description>This service runs the hello application</description>

  <executable>node.exe</executable>

  <!-- 
       {{dir}} will be expanded to the containing directory of your 
       config file, which is normally where your executable locates 
   -->
  <arguments>"{{dir}}\hello.js"</arguments>

  <logmode>rotate</logmode>

  <!-- OPTIONAL FEATURE:
       NODE_ENV=production will be an environment variable 
       available to your application, but not visible outside 
       of your application
   -->
  <env name="NODE_ENV" value="production"/>

  <!-- OPTIONAL FEATURE:
       FOO_SERVICE_PORT=8989 will be persisted as an environment
       variable machine-wide.
   -->
  <persistent_env name="FOO_SERVICE_PORT" value="8989" />
</service>

It seems like all answers here keep repeating to check for errors in the XML and clean your project. Do it! But what if that doesn't work? Here's what worked for me:

If you build a project that generates a wrong R and you delete it, it won't regenerate so delete this project and create new one, make sure you do NOT check "build automatically" then you can copy your folders into the workspace and THEN you clean the project or check "build automatically" so it will generate your R properly.

Very simple solution and test for JavaScript!

ToBase64 = function (u8) {
    return btoa(String.fromCharCode.apply(null, u8));
}

FromBase64 = function (str) {
    return atob(str).split('').map(function (c) { return c.charCodeAt(0); });
}

var u8 = new Uint8Array(256);
for (var i = 0; i < 256; i++)
    u8[i] = i;

var b64 = ToBase64(u8);
console.debug(b64);
console.debug(FromBase64(b64));

System.IO.Path.GetTempPath() is just a wrapper for a native call to GetTempPath(..) in Kernel32.

Have a look at http://msdn.microsoft.com/en-us/library/aa364992(VS.85).aspx

Copied from that page:

The GetTempPath function checks for the existence of environment variables in the following order and uses the first path found:

• The path specified by the TMP environment variable.
• The path specified by the TEMP environment variable.
• The path specified by the USERPROFILE environment variable.
• The Windows directory.

It's not entirely clear to me whether "The Windows directory" means the temp directory under windows or the windows directory itself. Dumping temp files in the windows directory itself sounds like an undesirable case, but who knows.

So combining that page with your post I would guess that either one of the TMP, TEMP or USERPROFILE variables for your Administrator user points to the windows path, or else they're not set and it's taking a fallback to the windows temp path.

2 things FYI -

1. For now, they've added a few toggle classes. See what's available in the latest stable release - print toggles in responsive-utilities.less
2. New and improved solution coming in Bootstrap 3.0 - they're adding a separate print.less file. See separate print.less

Are you using HTML5? If so, check whether you have any <input type="hidden"> in your form with the property required. Remove that required property. Internet Explorer won't take this property, so it works but Chrome will.

Use this : -- SQL Server 2008 or later

SELECT U.* 
FROM USERS AS U
Inner Join (
  SELECT   
    EMail, [Status]
  FROM
    (
      Values
        ('email1', 'Exist'),
        ('email2', 'Exist'),
        ('email3', 'Not Exist'),
        ('email4', 'Exist')
    )AS TempTableName (EMail, [Status])
  Where TempTableName.EMail IN ('email1','email2','email3')
) As TMP ON U.EMail = TMP.EMail

PHPExcel is your friend. Very easy to use and works like a charm.

https://github.com/PHPOffice/PHPExcel

I'd try to search for the solution by google and the string Python for statement, it is as simple as that. The first link says everything. (A great forum, really, but its usage seems to look sometimes like the usage of the Microsoft understanding of all their GUI products' benefits: windows inside, idiots outside.)

Spring won't allow to decouple via java.util.Properties from Spring Environment.

But Properties.load() still works in a Spring boot application:

Properties p = new Properties();
try (InputStream is = getClass().getResourceAsStream("/my.properties")) {
    p.load(is);
}

You should use Enum.TryParse to achive your goal

This is a example:

[Flags]
private enum TestEnum
{
    Value1 = 1,
    Value2 = 2
}

static void Main(string[] args)
{
    var enumName = "Value1";
    TestEnum enumValue;

    if (!TestEnum.TryParse(enumName, out enumValue))
    {
        throw new Exception("Wrong enum value");
    }

    // enumValue contains parsed value
}

I recommend PyInstaller, a simple python script can be converted to an exe with the following commands:

utils/Makespec.py [--onefile] oldlogs.py

which creates a yourprogram.spec file which is a configuration for building the final exe. Next command builds the exe from the configuration file:

utils/Build.py oldlogs.spec

More can be found here

You can also pass date format

df.withColumn("Date",to_date(unix_timestamp(df.col("your_date_column"), "your_date_format").cast("timestamp")))

For Example

import org.apache.spark.sql.functions._
val df = sc.parallelize(Seq("06 Jul 2018")).toDF("dateCol")
df.withColumn("Date",to_date(unix_timestamp(df.col("dateCol"), "dd MMM yyyy").cast("timestamp")))

I am using jquery or vw to keep the ratio

jquery

function setSize() {
    var $h = $('.cell').width();
    $('.your-img-class').height($h);
}
$(setSize);
$( window ).resize(setSize); 

vw

 .cell{
    width:30vw;
    height:30vw;
}
.cell img{
    width:100%;
    height:100%;
}

ModelName::find($id, ['name', 'surname']);

You can write an event handler for onsubmit that removes the name attribute from all of the input fields that you want not to be included in the form submission.

Here's a quick untested example:

var noSubmitElements = [ 'someFormElementID1', 'someFormElementID2' ]; //...
function submitForm() {
    for( var i = 0, j = noSubmitElements.length; i < j; i++ ) {
        document.getElementById(noSubmitElements[i]).removeAttribute('name');
    }
}
form.onsubmit = submitForm;

In addition to the other answers, I'd like to improve the removal, to something more generic:

$(this).closest('tr').remove();

This would be much better than using $(this).parent().parent().remove();, because it doesn't depend on the depth of the element. So, the structure of the row becomes much more flexible.

Are there more details? (Is this in a JSP as in the linked webpage?)

If so, you can always just use the fully qualified class name.
rather than:

import foo.bar.*;
Baz myBaz;

you can use

foo.bar.Baz myBaz;

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    cellIdentifier = @"myCell";
    cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    cell.myUILabel.lineBreakMode = UILineBreakModeWordWrap;        
    cell.myUILabel.numberOfLines = 0;
    cell.myUILabel.text = @"Some very very very very long text....."
    [cell.myUILabel.criterionDescriptionLabel sizeToFit];    
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
    CGFloat rowHeight = cell.myUILabel.frame.size.height + 10;

    return rowHeight;    
}

import java.lang.String;

This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).

The .first() will help here

$('p:contains("hello")').first().css('font-weight', 'bold');

Assignment, at its heart, is two steps: tearing down the object's old state and building its new state as a copy of some other object's state.

Basically, that's what the destructor and the copy constructor do, so the first idea would be to delegate the work to them. However, since destruction mustn't fail, while construction might, we actually want to do it the other way around: first perform the constructive part and, if that succeeded, then do the destructive part. The copy-and-swap idiom is a way to do just that: It first calls a class' copy constructor to create a temporary object, then swaps its data with the temporary's, and then lets the temporary's destructor destroy the old state.
Since swap() is supposed to never fail, the only part which might fail is the copy-construction. That is performed first, and if it fails, nothing will be changed in the targeted object.

In its refined form, copy-and-swap is implemented by having the copy performed by initializing the (non-reference) parameter of the assignment operator:

T& operator=(T tmp)
{
    this->swap(tmp);
    return *this;
}

A web application's context path is the directory that contains the web application's WEB-INF directory. It can be thought of as the 'home' of the web app. Often, when writing web applications, it can be important to get the actual location of this directory in the file system, since this allows you to do things such as read from files or write to files.

This location can be obtained via the ServletContext object's getRealPath() method. This method can be passed a String parameter set to File.separator to get the path using the operating system's file separator ("/" for UNIX, "\" for Windows).

Web containers are responsible to provide the run time environment to web applications. It contains components that provide naming context and manages the life cycle of a web application. Web containers are a part of a web server and they generally processes the user request and send a static response.

Servlet containers are the one where JSP created components reside. They are basically responsible to provide dynamic content as per the user request. Basically, Web containers reply with a static content as per the user request, but Servlets can create the dynamic pages.

You can try to do json.loads(), which will throw a ValueError if the string you pass can't be decoded as JSON.

In general, the "Pythonic" philosophy for this kind of situation is called EAFP, for Easier to Ask for Forgiveness than Permission.

The dynamic keyword is new to C# 4.0, and is used to tell the compiler that a variable's type can change or that it is not known until runtime. Think of it as being able to interact with an Object without having to cast it.

dynamic cust = GetCustomer();
cust.FirstName = "foo"; // works as expected
cust.Process(); // works as expected
cust.MissingMethod(); // No method found!

Notice we did not need to cast nor declare cust as type Customer. Because we declared it dynamic, the runtime takes over and then searches and sets the FirstName property for us. Now, of course, when you are using a dynamic variable, you are giving up compiler type checking. This means the call cust.MissingMethod() will compile and not fail until runtime. The result of this operation is a RuntimeBinderException because MissingMethod is not defined on the Customer class.

The example above shows how dynamic works when calling methods and properties. Another powerful (and potentially dangerous) feature is being able to reuse variables for different types of data. I'm sure the Python, Ruby, and Perl programmers out there can think of a million ways to take advantage of this, but I've been using C# so long that it just feels "wrong" to me.

dynamic foo = 123;
foo = "bar";

OK, so you most likely will not be writing code like the above very often. There may be times, however, when variable reuse can come in handy or clean up a dirty piece of legacy code. One simple case I run into often is constantly having to cast between decimal and double.

decimal foo = GetDecimalValue();
foo = foo / 2.5; // Does not compile
foo = Math.Sqrt(foo); // Does not compile
string bar = foo.ToString("c");

The second line does not compile because 2.5 is typed as a double and line 3 does not compile because Math.Sqrt expects a double. Obviously, all you have to do is cast and/or change your variable type, but there may be situations where dynamic makes sense to use.

dynamic foo = GetDecimalValue(); // still returns a decimal
foo = foo / 2.5; // The runtime takes care of this for us
foo = Math.Sqrt(foo); // Again, the DLR works its magic
string bar = foo.ToString("c");

The conversion is simple:

std::string str; LPCSTR lpcstr = str.c_str();

If you are using MYSQL-WORKBENCH, then you can select blob column normally and right click on column and click open value in editor. refer screenshot:

function addHidden(theForm, key, value) {
    // Create a hidden input element, and append it to the form:
    var input = document.createElement('input');
    input.type = 'hidden';
    input.name = key; //name-as-seen-at-the-server
    input.value = value;
    theForm.appendChild(input);
}

// Form reference:
var theForm = document.forms['detParameterForm'];

// Add data:
addHidden(theForm, 'key-one', 'value');

I'm afraid that's not possible. the rgba format you know is the only one.

I find using the pipe character with some top and bottom padding works well. Using a div with a border will require more CSS to vertically align it and get the horizontal spacing even with the other elements.

CSS

.divider-vertical {
    padding-top: 14px;
    padding-bottom: 14px;
}

HTML

<ul class="nav navbar-nav">
    <li class="active"><a href="#">Home</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">Faq</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">News</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">Contact</a></li>
</ul>

For quickly checking if mongodb is running, this quick nc trick will let you know.

nc -zvv localhost 27017

The above command assumes that you are running it on the default port on localhost.

For auto-starting it, you might want to look at this thread.

In javafx (using Gluon), the height is set at runtime or something like it. While being able to get the width just like normal...

double width = appBar.getWidth();

You have to create a listener:

GluonApplication application = this;

application.getAppBar().heightProperty().addListener(new ChangeListener(){
    @Override
    public void changed(ObservableValue observable, Object oldValue, Object newValue) {
        // Take most recent value given here
        application.getAppBar.heightProperty.get()
    }
});

...And take the most recent value it changed to. To get the height.

Use dictionary comprehension way,

x = {k:v for k,v in enumerate(states) if v == True}

Input:

states = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]

Output:

{4: True, 5: True, 7: True}

You will need to use the IO.Directory.GetFiles function.

Dim files() As String = IO.Directory.GetFiles("c:\")

For Each file As String In files
  ' Do work, example
  Dim text As String = IO.File.ReadAllText(file)
Next

For some programs setting the super secret __COMPAT_LAYER environment variable to RunAsInvoker will work.Check this :

set "__COMPAT_LAYER=RunAsInvoker"
start regedit.exe

Though like this there will be no UAC prompting the user will continue without admin permissions.

Updated 07/12/2016: Typescript 2.1 introduces Mapped Types and provides Partial<T>, which allows you to do this....

class Person {
    public name: string = "default"
    public address: string = "default"
    public age: number = 0;

    public constructor(init?:Partial<Person>) {
        Object.assign(this, init);
    }
}

let persons = [
    new Person(),
    new Person({}),
    new Person({name:"John"}),
    new Person({address:"Earth"}),    
    new Person({age:20, address:"Earth", name:"John"}),
];

Original Answer:

My approach is to define a separate fields variable that you pass to the constructor. The trick is to redefine all the class fields for this initialiser as optional. When the object is created (with its defaults) you simply assign the initialiser object onto this;

export class Person {
    public name: string = "default"
    public address: string = "default"
    public age: number = 0;

    public constructor(
        fields?: {
            name?: string,
            address?: string,
            age?: number
        }) {
        if (fields) Object.assign(this, fields);
    }
}

or do it manually (bit more safe):

if (fields) {
    this.name = fields.name || this.name;       
    this.address = fields.address || this.address;        
    this.age = fields.age || this.age;        
}

usage:

let persons = [
    new Person(),
    new Person({name:"Joe"}),
    new Person({
        name:"Joe",
        address:"planet Earth"
    }),
    new Person({
        age:5,               
        address:"planet Earth",
        name:"Joe"
    }),
    new Person(new Person({name:"Joe"})) //shallow clone
]; 

and console output:

Person { name: 'default', address: 'default', age: 0 }
Person { name: 'Joe', address: 'default', age: 0 }
Person { name: 'Joe', address: 'planet Earth', age: 0 }
Person { name: 'Joe', address: 'planet Earth', age: 5 }
Person { name: 'Joe', address: 'default', age: 0 }   

This gives you basic safety and property initialization, but its all optional and can be out-of-order. You get the class's defaults left alone if you don't pass a field.

You can also mix it with required constructor parameters too -- stick fields on the end.

About as close to C# style as you're going to get I think (actual field-init syntax was rejected). I'd much prefer proper field initialiser, but doesn't look like it will happen yet.

For comparison, If you use the casting approach, your initialiser object must have ALL the fields for the type you are casting to, plus don't get any class specific functions (or derivations) created by the class itself.

I've reviewed answers and comments for this and a number of similar threads. Be aware that none of the following commands are correct for the purpose of being able to stash any specific tracked/untracked files:

• git stash -p (--patch): select hunks manually, excluding untracked files
• git stash -k (--keep-index): stash all tracked/untracked files and keep them in the working directory
• git stash -u (--include-untracked): stash all tracked/untracked files
• git stash -p (--patch) -u (--include-untracked): invalid command

Currently, the most reasonable method to be able to stash any specific tracked/untracked files is to:

• Temporarily commit the files you don't want to stash
• Add and stash
• Pop the temporary commit

I wrote a simple script for this procedure in an answer to another question, and there are steps for performing the procedure in SourceTree here.

Try this:

$array = array_values($array);

Using array_values()

I find that some of these answers are vague and complicated, I find the best way to figure out these things for sure is to just open up the console and test it yourself.

var x;

x == null            // true
x == undefined       // true
x === null           // false
x === undefined      // true

var y = null;

y == null            // true
y == undefined       // true
y === null           // true
y === undefined      // false

typeof x             // 'undefined'
typeof y             // 'object'

var z = {abc: null};

z.abc == null        // true
z.abc == undefined   // true
z.abc === null       // true
z.abc === undefined  // false

z.xyz == null        // true
z.xyz == undefined   // true
z.xyz === null       // false
z.xyz === undefined  // true

null = 1;            // throws error: invalid left hand assignment
undefined = 1;       // works fine: this can cause some problems

So this is definitely one of the more subtle nuances of JavaScript. As you can see, you can override the value of undefined, making it somewhat unreliable compared to null. Using the == operator, you can reliably use null and undefined interchangeably as far as I can tell. However, because of the advantage that null cannot be redefined, I might would use it when using ==.

For example, variable != null will ALWAYS return false if variable is equal to either null or undefined, whereas variable != undefined will return false if variable is equal to either null or undefined UNLESS undefined is reassigned beforehand.

You can reliably use the === operator to differentiate between undefined and null, if you need to make sure that a value is actually undefined (rather than null).

According to the ECMAScript 5 spec:

• Both Null and Undefined are two of the six built in types.

4.3.9 undefined value

primitive value used when a variable has not been assigned a value

4.3.11 null value

primitive value that represents the intentional absence of any object value

What is the meaning of parameter -1?

You can read -1 as dynamic number of parameters or "anything". Because of that there can be only one parameter -1 in view().

If you ask x.view(-1,1) this will output tensor shape [anything, 1] depending on the number of elements in x. For example:

import torch
x = torch.tensor([1, 2, 3, 4])
print(x,x.shape)
print("...")
print(x.view(-1,1), x.view(-1,1).shape)
print(x.view(1,-1), x.view(1,-1).shape)

Will output:

tensor([1, 2, 3, 4]) torch.Size([4])
...
tensor([[1],
        [2],
        [3],
        [4]]) torch.Size([4, 1])
tensor([[1, 2, 3, 4]]) torch.Size([1, 4])

def time_to_sec(t):

time_to_sec(t)  # 38420

I just wanted to add to the great Flexbox solution described by Pavlo, that, in my case, I had two lists/columns of data that I wanted to display side-by-side with just a little spacing between, horizontally-centered inside an enclosing div. By nesting another div within the first (leftmost) flex:1 div and floating it right, I got just what I wanted. I couldn't find any other way to do this with consistent success at all viewport widths:

<div style="display:flex">
    <div style="flex:1;padding-right:15px">
        <div style="float:right">
            [My Left-hand list of stuff]
        </div>
    </div>

    <div style="flex:1;padding-left:15px">
            [My Right-hand list of stuff]
    </div>
</div>

The mice answer is great... And here is the description of the real problem:

The short simple answer is that Paint.getTextBounds(String text, int start, int end, Rect bounds) returns Rect which doesn't starts at (0,0). That is, to get actual width of text that will be set by calling Canvas.drawText(String text, float x, float y, Paint paint) with the same Paint object from getTextBounds() you should add the left position of Rect. Something like that:

public int getTextWidth(String text, Paint paint) {
    Rect bounds = new Rect();
    paint.getTextBounds(text, 0, end, bounds);
    int width = bounds.left + bounds.width();
    return width;
}

Notice this bounds.left - this the key of the problem.

In this way you will receive the same width of text, that you would receive using Canvas.drawText().

And the same function should be for getting height of the text:

public int getTextHeight(String text, Paint paint) {
    Rect bounds = new Rect();
    paint.getTextBounds(text, 0, end, bounds);
    int height = bounds.bottom + bounds.height();
    return height;
}

P.s.: I didn't test this exact code, but tested the conception.

Much more detailed explanation is given in this answer.

You should use () to group your boolean vector to remove ambiguity.

df = df[(df['closing_price'] >= 99) & (df['closing_price'] <= 101)]

You can find here the official javadoc of the support-annotationslibrary.

Error:(3, 31) error: package com.android.annotations does not exist

As you can see all the classes are in the same package android.support.annotation and not com.android.annotations.

Error:(7, 2) error: cannot find symbol class NonNullByDefault

Also the class NonNullByDefault doesn't exist in that package.

Here is a little utility function that collapses a named or unnamed list of values to a single string for easier printing. It will also print the code line itself. It's from my list examples in R page.

Generate some lists named or unnamed:

# Define Lists
ls_num <- list(1,2,3)
ls_str <- list('1','2','3')
ls_num_str <- list(1,2,'3')

# Named Lists
ar_st_names <- c('e1','e2','e3')
ls_num_str_named <- ls_num_str
names(ls_num_str_named) <- ar_st_names

# Add Element to Named List
ls_num_str_named$e4 <- 'this is added'

Here is the a function that will convert named or unnamed list to string:

ffi_lst2str <- function(ls_list, st_desc, bl_print=TRUE) {

  # string desc
  if(missing(st_desc)){
    st_desc <- deparse(substitute(ls_list))
  }

  # create string
  st_string_from_list = paste0(paste0(st_desc, ':'), 
                               paste(names(ls_list), ls_list, sep="=", collapse=";" ))

  if (bl_print){
    print(st_string_from_list)
  }
}

Testing the function with the lists created prior:

> ffi_lst2str(ls_num)
[1] "ls_num:=1;=2;=3"
> ffi_lst2str(ls_str)
[1] "ls_str:=1;=2;=3"
> ffi_lst2str(ls_num_str)
[1] "ls_num_str:=1;=2;=3"
> ffi_lst2str(ls_num_str_named)
[1] "ls_num_str_named:e1=1;e2=2;e3=3;e4=this is added"

Testing the function with subset of list elements:

> ffi_lst2str(ls_num_str_named[c('e2','e3','e4')])
[1] "ls_num_str_named[c(\"e2\", \"e3\", \"e4\")]:e2=2;e3=3;e4=this is added"
> ffi_lst2str(ls_num[2:3])
[1] "ls_num[2:3]:=2;=3"
> ffi_lst2str(ls_str[2:3])
[1] "ls_str[2:3]:=2;=3"
> ffi_lst2str(ls_num_str[2:4])
[1] "ls_num_str[2:4]:=2;=3;=NULL"
> ffi_lst2str(ls_num_str_named[c('e2','e3','e4')])
[1] "ls_num_str_named[c(\"e2\", \"e3\", \"e4\")]:e2=2;e3=3;e4=this is added"

I would suggest separating your code based on the functionality and purpose specific to each sheet or module. In this manner, you would only put code relative to a sheet's UI inside the sheet's module and only put code related to modules in respective modules. Also, use separate modules to encapsulate code that is shared or reused among several different sheets.

For example, let's say you multiple sheets that are responsible for displaying data from a database in a special way. What kinds of functionality do we have in this situation? We have functionality related to each specific sheet, tasks related to getting data from the database, and tasks related to populating a sheet with data. In this case, I might start with a module for the data access, a module for populating a sheet with data, and within each sheet I'd have code for accessing code in those modules.

It might be laid out like this.

Module: DataAccess:

Function GetData(strTableName As String, strCondition1 As String) As Recordset
    'Code Related to getting data from the database'
End Function

Module: PopulateSheet:

Sub PopulateASheet(wsSheet As Worksheet, rs As Recordset)
    'Code to populate a worksheet '
End Function

Sheet: Sheet1 Code:

Sub GetDataAndPopulate()
    'Sample Code'
     Dim rs As New Recordset
     Dim ws As Worksheet
     Dim strParam As String
     Set ws = ActiveSheet
     strParam = ws.Range("A1").Value

     Set rs = GetData("Orders",strParam)

     PopulateASheet ws, rs
End Sub

Sub Button1_Click()
    Call GetDataAndPopulate
End Sub

// read file and make object
let content = JSON.parse(fs.readFileSync('file.json', 'utf8'));

content.expiry_date = 999999999999;

I have a maths degree from Oxford too! It took me a while to 'get' the new collections stuff. But I like it a lot now that I do. In fact, the typing of 'map' was one of the first big things that bugged me in 2.7 (perhaps since the first thing I did was subclass one of the collection classes).

Reading Martin's paper on the new 2.8 collections really helped explain the use of implicits, but yes the documentation itself definitely needs to do a better job of explaining the role of different kind of implicits within method signatures of core APIs.

My main concern is more this: when is 2.8 going to be released? When will the bug reports stop coming in for it? have scala team bitten off more than they can chew with 2.8 / tried to change too much at once?

I'd really like to see 2.8 stabilised for release as a priority before adding anything else new at all, and wonder (while watching from the sidelines) if some improvements could be made to the way the development roadmap for the scala compiler is managed.

I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:

        ...
        var signature = Get(url); // base64_encoded signature received from server
        var inputtext= "inputtext"; // this is main text signature was created for
        bool result = VerifySignature(inputtext, signature);
        ...

    private bool VerifySignature(string input, string signature)
    {
        var result = false;
        using (var cps=new RSACryptoServiceProvider())
        {
            // converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
            byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
            byte[] signatureBytes  = Convert.FromBase64String(signature);

            cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
            result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes  );
        }

        return result;
    }

I use VisualStudioClean which is easy to understand and predictable. Knowing how it works and what files it is going to delete relieves me.

Previously I tried VSClean (note VisualStudioClean is not VSClean), VSClean is more advanced, it has many configurations that sometimes makes me wondering what files it is going to delete? One mis-configuration will result in lose of my source codes. Testing how the configuration will work need backing up all my projects which take a lot of times, so in the end I choose VisualStudioClean instead.

Conclusion : VisualStudioClean if you want basic cleaning, VSClean for more complex scenario.

If the background doesn't have to repeat, you can use the sprite technique (sliding-doors) where you put all the images with differing opacity into one (next to each other) and then just shift them around with background-position.

Or you could declare the same partially transparent background image more than once, if your target browser supports multiple backgrounds (Firefox 3.6+, Safari 1.0+, Chrome 1.3+, Opera 10.5+, Internet Explorer 9+). The opacity of those multiple images should add up, the more backgrounds you define.

This process of combining transparencies is called Alpha Blending and calculated as (thanks @IainFraser):

a? = a1 + a2(1-a1) where a ranges between 0 and 1.

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

Your struct is called struct xyx but a is of type struct xyz. Once you fix that, the output is 100.

#include <stdio.h>

struct xyx {
    int x;
    int y;
    char c;
    char str[20];
    int arr[2];
};

int main(void)
{
    struct xyx a;
    a.x = 100;
    printf("%d\n", a.x);
    return 0;
}

You get the error because if can only evaluate a logical vector of length 1.

Maybe you miss the difference between & (|) and && (||). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:

c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE

# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE

You don't need the if statement at all:

mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

What the selected answer is doing is actually wrong. The below function will return the bit position or 0 depending on if the bit is actually enabled. This is not what the poster was asking for.

#define CHECK_BIT(var,pos) ((var) & (1<<(pos)))

Here is what the poster was originally looking for. The below function will return either a 1 or 0 if the bit is enabled and not the position.

#define CHECK_BIT(var,pos) (((var)>>(pos)) & 1)

That doesn't work because the second parameter should be a mapped entity and of course Integer is not a persistent class (since it doesn't have the @Entity annotation on it).

for you you should do the following:

Query q = em.createNativeQuery("select id from users where username = :username");
q.setParameter("username", "lt");
List<BigDecimal> values = q.getResultList();

or if you want to use HQL you can do something like this:

Query q = em.createQuery("select new Integer(id) from users where username = :username");
q.setParameter("username", "lt");
List<Integer> values = q.getResultList();

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

If you are a linux user Update node to a later version by running

sudo apt update

 sudo apt install build-essential checkinstall libssl-dev

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash

nvm --version

nvm ls

nvm ls-remote

nvm install [version.number]

this should solve your problem

The problem with showing a file using Intent.ACTION_VIEW, is that if you pass the Uri parsing the path. Doesn't work in all cases. To fix that problem, you need to use:

Uri.fromFile(new File(filePath));

Instead of:

Uri.parse(filePath);

Edit

Here is my complete code:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(mediaFile.filePath)), mediaFile.getExtension());
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Info

MediaFile is my domain class to wrap files from database in objects. MediaFile.getExtension() returns a String with Mimetype for the file extension. Example: "image/png"

Aditional code: needed for showing any file (extension)

import android.webkit.MimeTypeMap;

public String getExtension () {
    MimeTypeMap myMime = MimeTypeMap.getSingleton();
    return myMime.getMimeTypeFromExtension(MediaFile.fileExtension(filePath));
}

public static String fileExtension(String path) {
    if (path.indexOf("?") > -1) {
        path = path.substring(0, path.indexOf("?"));
    }
    if (path.lastIndexOf(".") == -1) {
        return null;
    } else {
        String ext = path.substring(path.lastIndexOf(".") + 1);
        if (ext.indexOf("%") > -1) {
            ext = ext.substring(0, ext.indexOf("%"));
        }
        if (ext.indexOf("/") > -1) {
            ext = ext.substring(0, ext.indexOf("/"));
        }
        return ext.toLowerCase();
    }
}

Let me know if you need more code.

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug flags.

First as a baseline, try running

$ openssl s_client -connect host:443 -state -debug

You'll get a ton of output, but the lines we are interested in look like this:

SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03                        .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A

What's happening here:

• The -state flag is responsible for displaying the end of the previous section:

  SSL_connect:SSLv3 read server done A  
  

  This is only important for helping you find your place in the output.

• Then the -debug flag is showing the raw bytes being sent in the next step:

  write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
  0000 - 16 03 01 00 07 0b 00 00-03                        .........
  000c - <SPACES/NULS>
  

• Finally, the -state flag is once again reporting the result of the step that -debug just echoed:

  SSL_connect:SSLv3 write client certificate A
  

So in other words: s_client finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.

If you repeat the test, but this time include the -cert and -key flags like this:

$ openssl s_client -connect host:443 \
   -cert cert_and_key.pem \
   -key cert_and_key.pem  \
   -state -debug

your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:

SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31   ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11-                          ..^%/lC.
SSL_connect:SSLv3 write client certificate A

The 1576 bytes is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.

Requires Newtonsoft Json.Net

A little late, but I came up with this. It gives you just the keys and then you can use those on the dynamic:

public List<string> GetPropertyKeysForDynamic(dynamic dynamicToGetPropertiesFor)
{
    JObject attributesAsJObject = dynamicToGetPropertiesFor;
    Dictionary<string, object> values = attributesAsJObject.ToObject<Dictionary<string, object>>();
    List<string> toReturn = new List<string>();
    foreach (string key in values.Keys)
    {
        toReturn.Add(key);                
    }
    return toReturn;
}

Then you simply foreach like this:

foreach(string propertyName in GetPropertyKeysForDynamic(dynamicToGetPropertiesFor))
{
    dynamic/object/string propertyValue = dynamicToGetPropertiesFor[propertyName];
    // And
    dynamicToGetPropertiesFor[propertyName] = "Your Value"; // Or an object value
}

Choosing to get the value as a string or some other object, or do another dynamic and use the lookup again.

For Tomcat v8.5.4 and above, the file <tomcat>/webapps/manager/META-INF/context.xml has been adjusted:

<Context antiResourceLocking="false" privileged="true" >
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
</Context>

Change this file to comment the Valve:

<Context antiResourceLocking="false" privileged="true" >
    <!--
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
    -->
</Context>

After that, refresh your browser (not need to restart Tomcat), you can see the manager page.

brew switch libfoo mycopy

You can use brew switch to switch between versions of the same package, if it's installed as versioned subdirectories under Cellar/<packagename>/

This will list versions installed ( for example I had Cellar/sdl2/2.0.3, I've compiled into Cellar/sdl2/2.0.4)

brew info sdl2

Then to switch between them

brew switch sdl2 2.0.4
brew info 

Info now shows * next to the 2.0.4

To install under Cellar/<packagename>/<version> from source you can do for example

cd ~/somewhere/src/foo-2.0.4
./configure --prefix $(brew --Cellar)/foo/2.0.4
make

check where it gets installed with

make install -n

if all looks correct

make install

Then from cd $(brew --Cellar) do the switch between version.

I'm using brew version 0.9.5

Loop through the file.

f = open("masters.txt")
lines = f.readlines()
for line in lines:
    print line

The performance should be identical, but I would suggest using the join-version due to improved clarity when it comes to outer joins.

Also unintentional cartesian products can be avoided using the join-version.

A third effect is an easier to read SQL with a simpler WHERE-condition.

  select t1.id, t1.count, SUM(t2.count) cumulative_sum
    from table t1 
        join table t2 on t1.id >= t2.id
    group by t1.id, t1.count

Step by step:

1- Given the following table:

select *
from table t1 
order by t1.id;

id  | count
 1  |  11
 2  |  12   
 3  |  13

2 - Get information by groups

select *
from table t1 
    join table t2 on t1.id >= t2.id
order by t1.id, t2.id;

id  | count | id | count
 1  | 11    | 1  |  11

 2  | 12    | 1  |  11
 2  | 12    | 2  |  12

 3  | 13    | 1  |  11
 3  | 13    | 2  |  12
 3  | 13    | 3  |  13

3- Step 3: Sum all count by t1.id group

select t1.id, t1.count, SUM(t2.count) cumulative_sum
from table t1 
    join table t2 on t1.id >= t2.id
group by t1.id, t1.count;


id  | count | cumulative_sum
 1  |  11   |    11
 2  |  12   |    23
 3  |  13   |    36

The good old vim[grep] command..

• \c for case insensitive
• \C for case sensitive
• % is to search in the current buffer

I came late for this but I think this function makes exactly what OP requests. You can easily change the SENTENCE and the LIMIT values for different results.

function breakSentence(word, limit) {_x000D_
  const queue = word.split(' ');_x000D_
  const list = [];_x000D_
_x000D_
  while (queue.length) {_x000D_
    const word = queue.shift();_x000D_
_x000D_
    if (word.length >= limit) {_x000D_
      list.push(word)_x000D_
    }_x000D_
    else {_x000D_
      let words = word;_x000D_
_x000D_
      while (true) {_x000D_
        if (!queue.length ||_x000D_
            words.length > limit ||_x000D_
            words.length + queue[0].length + 1 > limit) {_x000D_
          break;_x000D_
        }_x000D_
_x000D_
        words += ' ' + queue.shift();_x000D_
      }_x000D_
_x000D_
      list.push(words);_x000D_
    }_x000D_
  }_x000D_
_x000D_
  return list;_x000D_
}_x000D_
_x000D_
const SENTENCE = 'the quick brown fox jumped over the lazy dog';_x000D_
const LIMIT = 11;_x000D_
_x000D_
// get result_x000D_
const words = breakSentence(SENTENCE, LIMIT);_x000D_
_x000D_
// transform the string so the result is easier to understand_x000D_
const wordsWithLengths = words.map((item) => {_x000D_
  return `[${item}] has a length of - ${item.length}`;_x000D_
});_x000D_
_x000D_
console.log(wordsWithLengths);

The output of this snippet is where the LIMIT is 11 is:

[ '[the quick] has a length of - 9',
  '[brown fox] has a length of - 9',
  '[jumped over] has a length of - 11',
  '[the lazy] has a length of - 8',
  '[dog] has a length of - 3' ]

This works for me...

• go to GenyMotion settings -> ADB tab
• instead of Use Genymotion Android tools, choose custom Android SDK Tools and then browse your installed SDK.

Probably the simplest way is to use curl for this, there is no need to install any additional packages and it can be configured directly in a request.

Here is an example using gmail smtp server:

curl --url 'smtps://smtp.gmail.com:465' --ssl-reqd \
  --mail-from '[email protected]' \
  --mail-rcpt '[email protected]' \
  --user '[email protected]:YourPassword' \
  -T <(echo -e 'From: [email protected]\nTo: [email protected]\nSubject: Curl Test\n\nHello')

You can use the simple mailto, see below for the simple markup.

<a href="mailto:[email protected]">Click here to mail</a>

Once clicked, it will open your Outlook or whatever email client you have set.

I tried Noah's suggestion which leads to the best solution up to now.

Just insert \let\cleardoublepage\clearpage before all the parts with the blank pages Especially when you use \documentclass[12pt,a4paper]{book}

frederic snyers's advice \documentclass[oneside]{book} is also very good and solves the problem, but if we just want to use the book.cls or article.cls, the one would make a big difference presenting your particles.

Hence, Big support to \let\cleardoublepage\clearpage for the people who will ask the same question in the future.

Who can beat it?

'#' + Math.random().toString(16).substr(-6);

It is guaranteed to work all the time: http://jsbin.com/OjELIfo/2/edit

Based on eterps's comment, the code above can still generate shorter strings if the hexadecimal representation of the random color is very short (0.730224609375 => 0.baf).

This code should work in all cases:

function makeRandomColor(){
  var c = '';
  while (c.length < 7) {
    c += (Math.random()).toString(16).substr(-6).substr(-1)
  }
  return '#' + c;
}

About the INT, TINYINT... These are different data types, INT is 4-byte number, TINYINT is 1-byte number. More information here - INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT.

The syntax of TINYINT data type is TINYINT(M), where M indicates the maximum display width (used only if your MySQL client supports it).

Numeric Type Attributes.

You were almost there:

You just need to append the li to ul and voila!

So just add

ul.appendChild(li);

to the end of your function so the end function will be like this:

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Element 4"));
  ul.appendChild(li);
}

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

Probably one of the indexes is wrong, either the inner one or the outer one.

I suspect you mean to say [0] where you say [1] and [1] where you say [2]. Indexes are 0-based in Python.

You have two ways to do that, both use the Arrays utility class

1. Implement a Comparator and pass your array along with the comparator to the sort method which take it as second parameter.
2. Implement the Comparable interface in the class your objects are from and pass your array to the sort method which takes only one parameter.

Example

class Book implements Comparable<Book> {
    public String name, id, author, publisher;
    public Book(String name, String id, String author, String publisher) {
        this.name = name;
        this.id = id;
        this.author = author;
        this.publisher = publisher;
    }
    public String toString() {
        return ("(" + name + ", " + id + ", " + author + ", " + publisher + ")");
    }
    @Override
    public int compareTo(Book o) {
        // usually toString should not be used,
        // instead one of the attributes or more in a comparator chain
        return toString().compareTo(o.toString());
    }
}

@Test
public void sortBooks() {
    Book[] books = {
            new Book("foo", "1", "author1", "pub1"),
            new Book("bar", "2", "author2", "pub2")
    };

    // 1. sort using Comparable
    Arrays.sort(books);
    System.out.println(Arrays.asList(books));

    // 2. sort using comparator: sort by id
    Arrays.sort(books, new Comparator<Book>() {
        @Override
        public int compare(Book o1, Book o2) {
            return o1.id.compareTo(o2.id);
        }
    });
    System.out.println(Arrays.asList(books));
}

Output

[(bar, 2, author2, pub2), (foo, 1, author1, pub1)]
[(foo, 1, author1, pub1), (bar, 2, author2, pub2)]

The string literal is pased according to the current dateformat setting, see SET DATEFORMAT. One format which will always work is the '20090525' one.

Now, of course, you need to define 'does not work'. No records gets updated? Perhaps the Id=1 doesn't match any record...

If it says 'One record changed' then perhaps you need to show us how you verify...

Ok, here's what I've got in my app. It includes a hack to prevent ListViews from going black while scrolling.

In C, the type of a character constant like 'a' is actually an int, with size of 4 (or some other implementation-dependent value). In C++, the type is char, with size of 1. This is one of many small differences between the two languages.

It depends on what you define as the difference. To compare two dates at midnight you can do.

long day1 = ...; // in milliseconds.
long day2 = ...; // in milliseconds.
long days = (day2 - day1) / 86400000;

I met some problems in Clion and finally, I solved them. Here is some experience.

1. Download and install MinGW
2. g++ and gcc package should be installed by default. Use the MinGW installation manager to install mingw32-libz and mingw32-make. You can open MinGW installation manager through C:\MinGW\libexec\mingw-get.exe This step is the most important step. If Clion cannot find make, C compiler and C++ compiler, recheck the MinGW installation manager to make every necessary package is installed.
3. In Clion, open File->Settings->Build,Execution,Deployment->Toolchains. Set MinGW home as your local MinGW file.
4. Start your "Hello World"!

I used:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

to disable the screen timeout and

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

to re-enable it.

Please note that increasing the Java heap size following an java.lang.OutOfMemoryError: Java heap space is quite often just a short term solution.

This means that even if you increase the default Java heap size from 512 MB to let's say 2048 MB, you may still get this error at some point if you are dealing with a memory leak. The main question to ask is why are you getting this OOM error at the first place? Is it really a Xmx value too low or just a symptom of another problem?

When developing a Java application, it is always crucial to understand its static and dynamic memory footprint requirement early on, this will help prevent complex OOM problems later on. Proper sizing of JVM Xms & Xmx settings can be achieved via proper application profiling and load testing.
