If you get an error similar like:

The following packages have unmet dependencies:
 libmagickwand-dev : Depends: libmagickcore4-extra (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed
                     Depends: libmagickcore-dev (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed

You might want to start with this package: sudo apt-get install libgvc5

Using imagemagick, you can try:

convert page.png page.pdf

Or for multiple images:

With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to write this with a briefer syntax:

>>> name = "Fred"
>>> f"He said his name is {name}."
'He said his name is Fred.'

With the example given in the question, it would look like this

plot.savefig(f'hanning{num}.pdf')

I had the exact same problem and it was driving me crazy (Windows 10 and VS Code 1.49.1)

Other answers talk about installing Selenium, but it's clear to me that you've already did that, but you still get the ImportError: No module named 'selenium'.

So, what's going on?

Two things:

1. You installed Selenium in this folder /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg
2. But you're probably running a version of Python, in which you didn't install Selenium. For instance: /Library/Python/3.8/site-packages... you won't find Selenium installed here and that's why the module isn't found.

The solution? You have to install selenium in the same directory to the Python version you're using or change the interpreter to match the directory where Selenium is installed.

In VS Code you change the interpreter here (at the bottom left corner of the screen)

Ready! Now your Python interpreter should find the module.

PDB is an abbreviation for Program Data Base. As the name suggests, it is a repository (persistent storage such as databases) to maintain information required to run your program in debug mode. It contains many important relevant information required while you debug your code (in Visual Studio), for e.g. at what points you have inserted break points where you expect the debugger to break in Visual Studio.

This is the reason why many times Visual Studio fails to hit the break points if you remove the *.pdb files from your debug folders. Visual Studio debugger is also able to tell you the precise line number of code file at which an exception occurred in a stack trace with the help of *.pdb files. So effectively pdb files are really a boon to developers while debugging a program.

Generally it is not recommended to exclude the generation of *.pdb files. From production release stand-point what you should be doing is create the pdb files but don't ship them to customer site in product installer. Preserve all the generated PDB files on to a symbol server from where it can be used/referenced in future if required. Specially for cases when you debug issues like process crash. When you start analysing the crash dump files and if your original *.pdb files created during the build process are not preserved then Visual Studio will not be able to make out the exact line of code which is causing crash.

If you still want to disable generation of *.pdb files altogether for any release then go to properties of the project -> Build Tab -> Click on Advanced button -> Choose none from "Debug Info" drop-down box -> press OK as shown in the snapshot below.

Note: This setting will have to be done separately for "Debug" and "Release" build configurations.

The stack pointer holds the address to the top of the stack. A stack allows functions to pass arguments stored on the stack to each other, and to create scoped variables. Scope in this context means that the variable is popped of the stack when the stack frame is gone, and/or when the function returns. Without a stack, you would need to use explicit memory addresses for everything. That would make it impossible (or at least severely difficult) to design high-level programming languages for the architecture. Also, each CPU mode usually have its own banked stack pointer. So when exceptions occur (interrupts for example), the exception handler routine can use its own stack without corrupting the user process.

As mentioned in the excellent answer by janoside, you need to construct the JSON string and set it as a StringEntity.

To construct the JSON string, you can use any library or method you are comfortable with. Jackson library is one easy example:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;

ObjectMapper mapper = new ObjectMapper();
ObjectNode node = mapper.createObjectNode();
node.put("name", "value"); // repeat as needed
String JSON_STRING = node.toString();
postMethod.setEntity(new StringEntity(JSON_STRING, ContentType.APPLICATION_JSON));

you didn't complete your try statement. You need and except in there too.

tldr; jsFiddle Demo

This functionality is not possible with an alert. However, you could use a div

function tempAlert(msg,duration)
{
 var el = document.createElement("div");
 el.setAttribute("style","position:absolute;top:40%;left:20%;background-color:white;");
 el.innerHTML = msg;
 setTimeout(function(){
  el.parentNode.removeChild(el);
 },duration);
 document.body.appendChild(el);
}

Use this like this:

tempAlert("close",5000);

$("#grid_GridHeader:first") works as well.

In my case, simply using the uxterm command instead of xterm solved the problem. It's available in /opt/X11/bin/uxterm by installing the XQuartz package provided by Apple.

You can use the Array.prototype.filter method:

var newArray = homes.filter(function (el) {
  return el.price <= 1000 &&
         el.sqft >= 500 &&
         el.num_of_beds >=2 &&
         el.num_of_baths >= 2.5;
});

Live Example:

var obj = {_x000D_
    'homes': [{_x000D_
            "home_id": "1",_x000D_
            "price": "925",_x000D_
            "sqft": "1100",_x000D_
            "num_of_beds": "2",_x000D_
            "num_of_baths": "2.0",_x000D_
        }, {_x000D_
            "home_id": "2",_x000D_
            "price": "1425",_x000D_
            "sqft": "1900",_x000D_
            "num_of_beds": "4",_x000D_
            "num_of_baths": "2.5",_x000D_
        },_x000D_
        // ... (more homes) ...     _x000D_
    ]_x000D_
};_x000D_
// (Note that because `price` and such are given as strings in your object,_x000D_
// the below relies on the fact that <= and >= with a string and number_x000D_
// will coerce the string to a number before comparing.)_x000D_
var newArray = obj.homes.filter(function (el) {_x000D_
  return el.price <= 1000 &&_x000D_
         el.sqft >= 500 &&_x000D_
         el.num_of_beds >= 2 &&_x000D_
         el.num_of_baths >= 1.5; // Changed this so a home would match_x000D_
});_x000D_
console.log(newArray);

This method is part of the new ECMAScript 5th Edition standard, and can be found on almost all modern browsers.

For IE, you can include the following method for compatibility:

if (!Array.prototype.filter) {
  Array.prototype.filter = function(fun /*, thisp*/) {
    var len = this.length >>> 0;
    if (typeof fun != "function")
      throw new TypeError();

    var res = [];
    var thisp = arguments[1];
    for (var i = 0; i < len; i++) {
      if (i in this) {
        var val = this[i];
        if (fun.call(thisp, val, i, this))
          res.push(val);
      }
    }
    return res;
  };
}

var switchData = $('#show-me');
switchData.hide();
$('input[type="radio"]').change(function(){ var inputData = $(this).attr("value");if(inputData == 'b') { switchData.show();}else{switchData.hide();}});

JSFIDDLE

This is happening because they're all referencing the same i variable, which is changing every loop, and left as 10 at the end of the loop. You can resolve it using a closure like this:

link.onclick = function(j) { return function() { onClickLink(j+''); }; }(i);

You can give it a try here

Or, make this be the link you clicked in that handler, like this:

link.onclick = function(j) { return function() { onClickLink.call(this, j); }; }(i);

You can try that version here

Seems there is another Node ng serve process running. Check it by typing this in your console (Linux/Mac):

ps aux|grep node

and quit it with:

kill -9 <NodeProcessId>

OR alternativley use

ng serve --port <AnotherFreePortNumber>

to serve your project on a free port of you choice.

Clearly HttpContext.Current is not null only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".

It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.

Overall, don't use Application["Setting"] to store global stuffs, as they are not global as you discovered.

If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext or Application["Settings"], as that violates the principles of isolation and decoupling.

Update: Due to the introduction of async/await it is more often that such issues happen, so you might consider the following tip,

In general, you should only call HttpContext.Current in only a few scenarios (within an HTTP module for example). In all other cases, you should use

• Page.Context https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2
• Controller.HttpContext https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2

instead of HttpContext.Current.

In the spirit of being complete, the answers that instruct you to use Guid.NewGuid() are correct.

In addressing your subsequent edit, you'll need to post the code for your RequestObject class. I'm suspecting that your guid property is not marked as a DataMember, and thus is not being serialized over the wire. Since default(Guid) is the same as new Guid() (i.e. all 0's), this would explain the behavior you're seeing.

For mysql 5.7.21 I use the following and works fine:

CREATE TABLE Posts ( modified_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP )

I wrote with parameters that are predefined

They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:

Alter Procedure [Test]
    @StartDate AS varchar(6) = NULL, 
    @EndDate AS varchar(6) = NULL
AS
...

NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.

Now you can call it without passing any arguments e.g. exec dbo.TEST

Try this:

 List<Double> l1= new ArrayList<Double>();
 l1.add(1.38);
 l1.add(2.56);
 l1.add(4.3);

I think this is the right way to make a shape like you want. By using the SVG possibilities, and an container to keep the shape responsive.

svg {_x000D_
  display: inline-block;_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
}_x000D_
.container {_x000D_
  display: inline-block;_x000D_
  position: relative;_x000D_
  width: 100%;_x000D_
  padding-bottom: 100%;_x000D_
  vertical-align: middle;_x000D_
  overflow: hidden;_x000D_
}

<div class="container">_x000D_
  <svg viewBox="0 0 500 500" preserveAspectRatio="xMinYMin meet">_x000D_
    <path d="M0,100 C150,200 350,0 500,100 L500,00 L0,0 Z" style="stroke: none; fill:red;"></path>_x000D_
  </svg>_x000D_
</div>

Images are not recommended since they may appear pixelated on some devices (Apple devices with Retina display) or when zoomed in. With a character, your list looks awesome everytime.

Here is the best solution I've found so far. It works great and it's cross-browser (IE 8+).

ul {
    list-style: none;
    padding-left: 1.2em;
    text-indent: -1.2em;
}

li:before {
    content: "?";
    display: block;
    float: left;
    width: 1.2em;
    color: #ff0000;
}

The important thing is to have the character in a floating block with a fixed width so that the text remains aligned if it's too long to fit on a single line. 1.2em is the width you want for your character, change it for your needs. Don't forget to reset padding and margin for ul and li elements.

EDIT: Be aware that the "1.2em" size may vary if you use a different font in ul and li:before. It's safer to use pixels.

If your project budged allows you to have enough RAM memory on your environment - answer is Redis. Especially taking in account new Redis 3.2 with cluster functionality.

There is an easier way to get the exact version .NET version installed on your machine from a cmd prompt. Just follow the following instructions;

Open the command prompt (i.e Windows + R ? type “cmd”) and type the following command, all on one line: %windir%\Microsoft.NET\FrameWork, and then navigating to the directory with the latest version number.

Refer to http://dotnettec.com/check-dot-net-framework-version/

DECLARE @test nvarchar(100)

SET @test = 'Foreign Tax Credit - 1997'

SELECT @test, left(@test, charindex('-', @test) - 2) AS LeftString,
    right(@test, len(@test) - charindex('-', @test) - 1)  AS RightString

WITH SensorTimes As (
   SELECT sensorID, MAX(timestamp) "LastReading"
   FROM sensorTable
   GROUP BY sensorID
)
SELECT s.sensorID,s.timestamp,s.sensorField1,s.sensorField2 
FROM sensorTable s
INNER JOIN SensorTimes t on s.sensorID = t.sensorID and s.timestamp = t.LastReading

An ID is meant to identify the element uniquely. Any styles applied to it should also be unique to that element. If you have styles you want to apply to many elements, you should add a class to them all, rather than relying on ID selectors...

<div id="sections">
   <div id="s1" class="sec">...</div>
   <div id="s2" class="sec">...</div>
   ...
</div>

and

.sec {
    ...
}

Or in your specific case you could select all divisions inside your parent container, if nothing else is inside it, like so:

#sections > div {
    ...
}

Use a subselect:

select name, date, time
from mytable main
where date + time = (select min(date + time) from mytable where name = main.mytable)
order by date + time;

Declare the object like this.

export interface Thread {
    id:number;
    messageIds: number[];
    participants: {
        [key:number]: number
    };
}

You should now use DbFunctions.TruncateTime

var anyCalls = _db.CallLogs.Where(r => DbFunctions.TruncateTime(r.DateTime) == callDateTime.Date).ToList();

Maven install plugin has command line usage to install a jar into the local repository, POM is optional but you will have to specify the GroupId, ArtifactId, Version and Packaging (all the POM stuff).

In SQL Server 2008 or above I use the following query to find all the dependant stored procedures, user defined functions, triggers, etc. for a given table:

SELECT 
coalesce(Referenced_server_name+'.','')+ --possible server name if cross-server
coalesce(referenced_database_name+'.','')+ --possible database name if cross-database
coalesce(referenced_schema_name+'.','')+ --likely schema name
coalesce(referenced_entity_name,'') + --very likely entity name
coalesce('.'+col_name(referenced_ID,referenced_minor_id),'')AS [referencing],
coalesce(object_schema_name(Referencing_ID)+'.','')+ --likely schema name
object_name(Referencing_ID)+ --definite entity name
coalesce('.'+col_name(referencing_ID,referencing_minor_id),'') AS [referenced]
FROM sys.sql_expression_dependencies
WHERE referenced_id =object_id('Table_name')
ORDER BY [referenced]

var asIntegers = arr.Select(s => int.Parse(s)).ToArray(); 

Have to make sure you are not getting an IEnumerable<int> as a return

Assuming that your List is a list of strings make data an ArrayList<String> and use intent.putStringArrayListExtra("data", data)

Here is a skeleton of the code you need:

1. Declare List

   private List<String> test;
   

2. Init List at appropriate place

   test = new ArrayList<String>();
   

   and add data as appropriate to test.

3. Pass to intent as follows:

   Intent intent = getIntent();  
   intent.putStringArrayListExtra("test", (ArrayList<String>) test);
   

4. Retrieve data as follows:

   ArrayList<String> test = getIntent().getStringArrayListExtra("test");
   

Hope that helps.

They are both instances of Context, but the application instance is tied to the lifecycle of the application, while the Activity instance is tied to the lifecycle of an Activity. Thus, they have access to different information about the application environment.

If you read the docs at getApplicationContext it notes that you should only use this if you need a context whose lifecycle is separate from the current context. This doesn't apply in either of your examples.

The Activity context presumably has some information about the current activity that is necessary to complete those calls. If you show the exact error message, might be able to point to what exactly it needs.

But in general, use the activity context unless you have a good reason not to.

I would suggest not using pixels for sWidth, instead use percentages. Like below:

   "aoColumnDefs": [
  { "sWidth": "20%", "aTargets": [ 0 ] }, <- start from zero
  { "sWidth": "5%", "aTargets": [ 1 ] },
  { "sWidth": "10%", "aTargets": [ 2 ] },
  { "sWidth": "5%", "aTargets": [ 3 ] },
  { "sWidth": "40%", "aTargets": [ 4 ] },
  { "sWidth": "5%", "aTargets": [ 5 ] },
  { "sWidth": "15%", "aTargets": [ 6 ] }
],
     aoColumns : [
      { "sWidth": "20%"},
      { "sWidth": "5%"},
      { "sWidth": "10%"},
      { "sWidth": "5%"},
      { "sWidth": "40%"},
      { "sWidth": "5%"},
      { "sWidth": "15%"}
    ]
});

Hope it helps.

If you want an explicit check against false (and not undefined, null and others which I assume as you are using !== instead of !=) then yes, you have to use that.

Also, this is the same in a slightly smaller footprint:

if(borrar() !== !1)

This solved my similar problem. I used it to revert the changes, then I added everything and commited changes in the terminal with

svn add folder_path/*
svn commit -m "message"

What you said above is correct. Sometimes final methods are created as inline, but there is no other way to explicitly create an inline function in java.

As user @aaracrr pointed out in a comment on another answer probably the best answer is to re-require the package with the same version constraint.

ie.

composer require vendor/package

or specifying a version constraint

composer require vendor/package:^1.0.0

If you want run formula on worksheet by function that execute SQL statement then use Add-in A-Tools

Example, function BS_SQL("SELECT ..."):

Benoit's solution works, but you really don't need to incur the overhead to draw a shape. Since colors can be drawables, just define a color in a /res/values/colors.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="semitransparent_white">#77ffffff</color>
</resources>

And then use as such in your selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true"
        android:drawable="@color/semitransparent_white" />
</selector>

echo $myarray[0]->['email'];

Try this only if it you are passing the stdclass object

Atomic size is 4096 bytes, max size is 65536 bytes. Sendfile uses 16 pipes each of 4096 bytes size. cmd : ioctl(fd, FIONREAD, &buff_size).

Such error happens when,

1. You misspell module name which you injected.
2. If you missed to include js file of that module.

Sometimes people write js file name instead of the module name which we are injecting.

In these cases what happens is angular tries to look for the module provided in the square bracket []. If it doesn't find the module, it throws error.

The encodings are spelled out in the buffer documentation.

Buffers and character encodings:

Character Encodings

• utf8: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.
• utf16le: Multi-byte encoded Unicode characters. Unlike utf8, each character in the string will be encoded using either 2 or 4 bytes.
• latin1: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters from U+0000 to U+00FF.

Binary-to-Text Encodings

• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• hex: Encode each byte as two hexadecimal characters.

Legacy Character Encodings

• ascii: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.
• binary: Alias for 'latin1'.
• ucs2: Alias of 'utf16le'.

IntelliJ IDEA vs WebStorm features

IntelliJ IDEA remains JetBrains' flagship product and IntelliJ IDEA provides full JavaScript support along with all other features of WebStorm via bundled or downloadable plugins. The only thing missing is the simplified project setup.

Taken from : https://confluence.jetbrains.com/display/WI/WebStorm+FAQ#WebStormFAQ-IntelliJIDEAvsWebStormfeatures

This worked for me.

var number = 8008
number = number + "";
numberreverse = number.split("").reverse().join('');
console.log ("The number if reversed is: " +numberreverse);
if (number == numberreverse)
    console.log("Yes, this is a palindrome");
else
    console.log("Nope! It isnt a palindrome");

I usually read command output in to variables using the FOR command as it saves having to create temporary files. For example:

FOR /F "usebackq" %i IN (`hostname`) DO SET MYVAR=%i

Note, the above statement will work on the command line but not in a batch file. To use it in batch file escape the % in the FOR statement by putting them twice:

FOR /F "usebackq" %%i IN (`hostname`) DO SET MYVAR=%%i
ECHO %MYVAR%

There's a lot more you can do with FOR. For more details just type HELP FOR at command prompt.

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

The reason why we have stdClass is because in PHP there is no way to distinguish a normal array from an associate array (like in Javascript you have {} for object and [] for array to distinguish them).

So this creates a problem for empty objects. Take this for example.

PHP:

$a = [1, 2, 3]; // this is an array
$b = ['one' => 1, 'two' => 2]; // this is an associate array (aka hash)
$c = ['a' => $a, 'b' => $b]; // this is also an associate array (aka hash)

Let's assume you want to JSON encode the variable $c

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': {one: 1, two: 2}}

Now let's say you deleted all the keys from $b making it empty. Since $b is now empty (you deleted all the keys remember?), it looks like [] which can be either an array or object if you look at it.

So if you do a json_encode again, the output will be different

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': []}

This is a problem because we know b that was supposed to be an associate array but PHP (or any function like json_encode) doesn't.

So stdClass comes to rescue. Taking the same example again

$a = [1, 2, 3]; // this is an array
$b = (object) ['one' => 1, 'two' => 2]; // this makes it an stdClass
$c = ['a' => $a, 'b' => $b]; // this is also an associate array (aka hash)

So now even if you delete all keys from $b and make it empty, since it is an stdClass it won't matter and when you json_encode it you will get this:

echo json_encode($c);
// outputs => {'a': [1,2,3], 'b': {}}

This is also the reason why json_encode and json_decode by default return stdClass.

 $c = json_decode('{"a": [1,2,3], "b": {}}', true); //true to deocde as array
 // $c is now ['a' => [1,2,3], 'b' => []] in PHP
 // if you json_encode($c) again your data is now corrupted

With Apache Commons Library, you can simply use Stringutils.replaceEach:

public static String replaceEach(String text,
                             String[] searchList,
                             String[] replacementList)

From the documentation:

Replaces all occurrences of Strings within another String.

A null reference passed to this method is a no-op, or if any "search string" or "string to replace" is null, that replace will be ignored. This will not repeat. For repeating replaces, call the overloaded method.

 StringUtils.replaceEach(null, *, *)        = null

  StringUtils.replaceEach("", *, *)          = ""

  StringUtils.replaceEach("aba", null, null) = "aba"

  StringUtils.replaceEach("aba", new String[0], null) = "aba"

  StringUtils.replaceEach("aba", null, new String[0]) = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, null)  = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, new String[]{""})  = "b"

  StringUtils.replaceEach("aba", new String[]{null}, new String[]{"a"})  = "aba"

  StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"w", "t"})  = "wcte"
  (example of how it does not repeat)

StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"d", "t"})  = "dcte"

If you are using GWT you will be limited to using java.util.Date, here is a method that takes the date as integers, but still uses java.util.Date:

public int getAge(int year, int month, int day) {
    Date now = new Date();
    int nowMonth = now.getMonth()+1;
    int nowYear = now.getYear()+1900;
    int result = nowYear - year;

    if (month > nowMonth) {
        result--;
    }
    else if (month == nowMonth) {
        int nowDay = now.getDate();

        if (day > nowDay) {
            result--;
        }
    }
    return result;
}

Using DELETE with a Body is risky... I prefer this approach for List Operations over REST:

Regular Operations

GET /objects/ Gets all Objects

GET /object/ID Gets an Object with specified ID

POST /objects Adds a new Object

PUT /object/ID Adds an Object with specified ID, Updates an Object

DELETE /object/ID Deletes the object with specified ID

All Custom actions are POST

POST /objects/addList Adds a List or Array of Objects included in body

POST /objects/deleteList Deletes a List of Objects included in body

POST /objects/customQuery Creates a List based on custom query in body

If a client doesn't support your extended operations they can work in the regular way.

I had a similar problem and the solution was in the right use of the '$' (end-of-string) character:

My main url.py looked like this (notice the $ character):

urlpatterns = [
url(r'^admin/', include(admin.site.urls )),
url(r'^$', include('card_purchase.urls' )),
]

and my url.py for my card_purchases app said:

urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^purchase/$', views.purchase_detail, name='purchase')
]

I used the '$' twice. So a simple change worked:

urlpatterns = [
url(r'^admin/', include(admin.site.urls )),
url(r'^cp/', include('card_purchase.urls' )),
]

Notice the change in the second url! My url.py for my card_purchases app looks like this:

urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^purchase/$', views.purchase_detail, name='purchase')
]

Apart from this, I can confirm that quotes around named urls are crucial!

Forming a XML file

XmlTextWriter xmlw = new XmlTextWriter(@"C:\WINDOWS\Temp\exm.xml",System.Text.Encoding.UTF8);
xmlw.WriteStartDocument();            
xmlw.WriteStartElement("examtimes");
xmlw.WriteStartElement("Starttime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Changetime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Endtime");
xmlw.WriteString(DateTime.Now.AddHours(1).ToString());
xmlw.WriteEndElement();
xmlw.WriteEndElement();
xmlw.WriteEndDocument();  
xmlw.Close();           

To edit the Xml nodes use the below code

XmlDocument doc = new XmlDocument(); 
doc.Load(@"C:\WINDOWS\Temp\exm.xml"); 
XmlNode root = doc.DocumentElement["Starttime"]; 
root.FirstChild.InnerText = "First"; 
XmlNode root1 = doc.DocumentElement["Changetime"]; 
root1.FirstChild.InnerText = "Second"; 
doc.Save(@"C:\WINDOWS\Temp\exm.xml"); 

Try this. It's C# code.

To get more than 20 you can use a load more button.

Find the function getTagMedia() and replace with:

public function getTagMedia($name, $auth=false, $params=null) {
    return $this->_makeCall('tags/' . $name . '/media/recent', $auth, $params);
}

The reason it is throwing that exception is because you have the argument rb, which opens the file in binary mode. Change that to r, which will by default open the file in text mode.

Your code:

import csv
ifile  = open('sample.csv', "rb")
read = csv.reader(ifile)
for row in read :
    print (row) 

New code:

import csv
ifile  = open('sample.csv', "r")
read = csv.reader(ifile)
for row in read :
    print (row)

I couldn't get the accepted answer to work the way I wanted it to (see Farrukh's comment).

I came up with a slightly different solution which also feels more native because it selects the item on mouse button down and then you're able to react to it when the mouse button gets released:

XAML:

<ListView Name="MyListView" ItemsSource={Binding MyItems}>
<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
        <EventSetter Event="PreviewMouseLeftButtonUp" Handler="ListViewItem_PreviewMouseLeftButtonUp" />
    </Style>
</ListView.ItemContainerStyle>

Code behind:

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    MyListView.SelectedItems.Clear();

    ListViewItem item = sender as ListViewItem;
    if (item != null)
    {
        item.IsSelected = true;
        MyListView.SelectedItem = item;
    }
}

private void ListViewItem_PreviewMouseLeftButtonUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    ListViewItem item = sender as ListViewItem;
    if (item != null && item.IsSelected)
    {
        // do stuff
    }
}

HTML5 Time Input

This one is the simplest of the date/time related types, allowing the user to select a time on a 24/12 hour clock, usually depending on the user's OS locale configuration. The value returned is in 24h hours:minutes format, which will look something like 14:30.

More details, including the appearance for each browser, can be found on MDN.

<input type="time" name="time" />

Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.

I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.

copy structure in c you just need to assign the values as follow:

struct RTCclk RTCclk1;
struct RTCclk RTCclkBuffert;

RTCclk1.second=3;
RTCclk1.minute=4;
RTCclk1.hour=5;

RTCclkBuffert=RTCclk1;

now RTCclkBuffert.hour will have value 5,

RTCclkBuffert.minute will have value 4

RTCclkBuffert.second will have value 3

None of the previous answers pointed out the root problem in my situation. So I hope this may be useful to someone else.

In my case I ended up having to edit my podfile at the root of my project. When I first created my podfile, swift static libraries were not supported. So I had been using use_frameworks! in my podfile under each of my targets as such:

BEFORE

...
target 'targetName' do
   use_frameworks!
   pod 'podName', '~> 0.2'
end

AFTER

...
target 'targetName' do
   pod 'podName', '~> 0.2'
end

I removed use_frameworks! from my podfile which kept installing the frameworks every time I ran pod install. After removing this line, make sure to run pod install again and remove any of the red .framework references from your Frameworks folder in Xcode. (Though mine appeared differently as attached below.)

You can also read more about use_framework! here.

I have two recommendation for you

1. Use CI Friendly Revision for all your artifacts. You can add -Drevision=2.0.1 in .mvn/maven.config file. So basically you define your version only at one location.
2. For all external dependency create a property in parent file. You can use Apache Camel Parent Pom as reference

"Empty": only works on variables. Empty can mean different things for different variable types (check manual: http://php.net/manual/en/function.empty.php).

"isset": checks if the variable exists and checks for a true NULL or false value. Can be unset by calling "unset". Once again, check the manual.

Use of either one depends of the variable type you are using.

I would say, it's safer to check for both, because you are checking first of all if the variable exists, and if it isn't really NULL or empty.

You may have started your docker with dns options --dns 172.x.x.x

I had the same error and removed the options from /etc/default/docker

The lines:

# Use DOCKER_OPTS to modify the daemon startup options.
DOCKER_OPTS="--dns 172.x.x.x"

If you have this problem and you have a gradle .jar dependency, like this:

implementation group: 'org.mortbay.jetty', name: 'jetty', version: '6.1.26'

Interval versions until one matches and resolves the excepetion,and apply the best answer of this thread.`

Make a HTML Table from a JSON array of Objects by extending $ as shown below

$.makeTable = function (mydata) {
    var table = $('<table border=1>');
    var tblHeader = "<tr>";
    for (var k in mydata[0]) tblHeader += "<th>" + k + "</th>";
    tblHeader += "</tr>";
    $(tblHeader).appendTo(table);
    $.each(mydata, function (index, value) {
        var TableRow = "<tr>";
        $.each(value, function (key, val) {
            TableRow += "<td>" + val + "</td>";
        });
        TableRow += "</tr>";
        $(table).append(TableRow);
    });
    return ($(table));
};

and use as follows:

var mydata = eval(jdata);
var table = $.makeTable(mydata);
$(table).appendTo("#TableCont");

where TableCont is some div

Migrate to Android X and use

implementation 'androidx.appcompat:appcompat:1.1.0'

and use LocationManagerCompat

In java

private boolean isLocationEnabled(Context context) {
    LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    return LocationManagerCompat.isLocationEnabled(locationManager);
}

In Kotlin

private fun isLocationEnabled(context: Context): Boolean {
    val locationManager = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
    return LocationManagerCompat.isLocationEnabled(locationManager)
}

Update:

implementation 'androidx.appcompat:appcompat:1.2.0'

$("td:contains('c')").html("new");

or, more precisely $("#table_headers td:contains('c')").html("new");

and maybe for reuse you could create a function to call

function ReplaceCellContent(find, replace)
{
    $("#table_headers td:contains('" + find + "')").html(replace);
}

*NIX (Linux, OS X, ...)

Use n, an extremely simple Node version manager that can be installed via npm.

Say you want Node.js v0.10.x to build Atom.

npm install -g n   # Install n globally
n 0.10.33          # Install and use v0.10.33

Usage:
n                            # Output versions installed
n latest                     # Install or activate the latest node release
n stable                     # Install or activate the latest stable node release
n <version>                  # Install node <version>
n use <version> [args ...]   # Execute node <version> with [args ...]
n bin <version>              # Output bin path for <version>
n rm <version ...>           # Remove the given version(s)
n --latest                   # Output the latest node version available
n --stable                   # Output the latest stable node version available
n ls                         # Output the versions of node available

Windows

Use nvm-windows, it's like nvm but for Windows. Download and run the installer, then:

nvm install v0.10.33         # Install v0.10.33
nvm use v0.10.33             # Use v0.10.33

Usage:
nvm install [version]        # Download and install [version]
nvm uninstall [version]      # Uninstall [version]
nvm use [version]            # Switch to use [version]
nvm list                     # List installed versions

turn on the org.hibernate.type Logger to see how the actual parameters are bind to the question marks.

This is the correct way to replace a portion of text inside a string (based upon the getBetween method by Oscar Jara):

public static string ReplaceTextBetween(string strSource, string strStart, string strEnd, string strReplace)
    {
        int Start, End, strSourceEnd;
        if (strSource.Contains(strStart) && strSource.Contains(strEnd))
        {
            Start = strSource.IndexOf(strStart, 0) + strStart.Length;
            End = strSource.IndexOf(strEnd, Start);
            strSourceEnd = strSource.Length - 1;

            string strToReplace = strSource.Substring(Start, End - Start);
            string newString = string.Concat(strSource.Substring(0, Start), strReplace, strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start));
            return newString;
        }
        else
        {
            return string.Empty;
        }
    }

The string.Concat concatenates 3 strings:

1. The string source portion before the string to replace found - strSource.Substring(0, Start)
2. The replacing string - strReplace
3. The string source portion after the string to replace found - strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start)

You can use the relationLoaded method on the model object. This saved my bacon so hopefully it helps someone else. I was given this suggestion when I asked the same question on Laracasts.

You need a json serializer to parse your content, probably you already have it, for your initial question on how to make a request, this might be an idea:

var baseAddress = "http://www.example.com/1.0/service/action";

var http = (HttpWebRequest)WebRequest.Create(new Uri(baseAddress));
http.Accept = "application/json";
http.ContentType = "application/json";
http.Method = "POST";

string parsedContent = <<PUT HERE YOUR JSON PARSED CONTENT>>;
ASCIIEncoding encoding = new ASCIIEncoding();
Byte[] bytes = encoding.GetBytes(parsedContent);

Stream newStream = http.GetRequestStream();
newStream.Write(bytes, 0, bytes.Length);
newStream.Close();

var response = http.GetResponse();

var stream = response.GetResponseStream();
var sr = new StreamReader(stream);
var content = sr.ReadToEnd();

It's a rectangle that prevents oval shape background to get circular.
Making view a square will fix everything.

I found this solution to be clean and working for varying textsize and text length.

public class EqualWidthHeightTextView extends TextView {

    public EqualWidthHeightTextView(Context context) {
        super(context);
    }

    public EqualWidthHeightTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public EqualWidthHeightTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int r = Math.max(getMeasuredWidth(),getMeasuredHeight());
        setMeasuredDimension(r, r);

    }
}

Usage

<com.commons.custom.ui.EqualWidthHeightTextView
    android:id="@+id/cluster_count"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="10+"
    android:background="@drawable/oval_light_blue_bg"
    android:textColor="@color/white" />

If you want easy to use libraries, you can use the NUGET packages:

• ExcelDataReader - to read Excel files (most file formats)
• SwiftExcel - to write Excel files (.xlsx)

Note these are 3rd-Party packages - you can use them for basic functionality for free, but if you want more features there might be a "pro" version.

They are using a two-dimensional object array (i.e. object[][] cells) to read / write data.

You need to tell the query what value to pick for the other columns, MIN or MAX seem like suitable choices.

 SELECT
   U.NAME, MIN(P.PIC_ID)
 FROM
   USERS U,
   PICTURES P,
   POSTINGS P1
 WHERE
   U.EMAIL_ID = P1.EMAIL_ID AND
   P1.PIC_ID = P.PIC_ID AND
   P.CAPTION LIKE '%car%'
 GROUP BY
   U.NAME;

You cannot update UI from any other thread other than the UI thread. Use this to update thread on the UI thread.

 private void AggiornaContatore()
 {         
     if(this.lblCounter.InvokeRequired)
     {
         this.lblCounter.BeginInvoke((MethodInvoker) delegate() {this.lblCounter.Text = this.index.ToString(); ;});    
     }
     else
     {
         this.lblCounter.Text = this.index.ToString(); ;
     }
 }

Please go through this chapter and more from this book to get a clear picture about threading:

For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this

 dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha4'   
          ....
    }

then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

Try the below, where strDate is your date in 'MM/dd/yyyy' format

var date = DateTime.Parse(strDate,new CultureInfo("en-US", true))

Make sure the path to scripts folder for the python version is added to the path environment/system variable in order to use pip command directly without the whole path to pip.exe which is inside the scripts folder.

The scripts folder would be inside the python folder for the version that you are using, which by default would be inside c drive or in c:/program files or c:/program files (x86).

Then use commands as mentioned below. You may have to run cmd as administrator to perform these tasks. You can do it by right clicking on cmd icon and selecting run as administrator.

python -m pip install packagename
python -m pip uninstall packagename
python -m pip install --upgrade packagename

In case you have more than one version of python. You may replace python with py -versionnumber for example py -2 for python 2 or you may replace it with the path to the corresponding python.exe file. For example "c:\python27\python".

Search in your code maybe you have initialized dataTable twice in your code. You shold have like this code:

$('#example').dataTable( {paging: false} );

Only one time in your code.

when using (i.e.) getConstructor(String.lang) the constructor has to be declared public. Otherwise a NoSuchMethodException is thrown.

if you want to access a non-public constructor you have to use instead (i.e.) getDeclaredConstructor(String.lang).

probably graded as a non-pythonic way to do this but this'll give the result you want in a line:

Output: [['i', 'k'], 't']

You need to use multiple rules to implement OR-like semantics, since matches are always AND-ed together within a rule. Alternatively, you can do matching against port-indexing ipsets (ipset create blah bitmap:port).

if ([ $NUM1 == 1 ] || [ $NUM2 == 1 ]) && [ -z "$STR" ]
then
    echo STR is empty but should have a value.
fi

If you want the column names of your dataframe, you can use the pyspark.sql class. I'm not sure if the SDK supports explicitly indexing a DF by column name. I received this traceback:

>>> df.columns['High'] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: list indices must be integers, not str

However, calling the columns method on your dataframe, which you have done, will return a list of column names:

df.columns will return ['Date', 'Open', 'High', 'Low', 'Close', 'Volume', 'Adj Close']

If you want the column datatypes, you can call the dtypes method:

df.dtypes will return [('Date', 'timestamp'), ('Open', 'double'), ('High', 'double'), ('Low', 'double'), ('Close', 'double'), ('Volume', 'int'), ('Adj Close', 'double')]

If you want a particular column, you'll need to access it by index:

df.columns[2] will return 'High'

Set equal name attributes to create a group;

<form>_x000D_
  <fieldset id="group1">_x000D_
    <input type="radio" value="value1" name="group1">_x000D_
    <input type="radio" value="value2" name="group1">_x000D_
  </fieldset>_x000D_
_x000D_
  <fieldset id="group2">_x000D_
    <input type="radio" value="value1" name="group2">_x000D_
    <input type="radio" value="value2" name="group2">_x000D_
    <input type="radio" value="value3" name="group2">_x000D_
  </fieldset>_x000D_
</form>

just for development in windows

$Env:NODE_TLS_REJECT_UNAUTHORIZED=0 

I also faced the same issue. I found the solutions like following.

Solution 1: I kept my script tag in the body.

<body>
   <form> . . . .  </form>
    <script type="text/javascript" src="<%= My.Working.Common.Util.GetSiteLocation()%>Scripts/Common.js"></script> </body>

Now conflicts regarding the tags will resolve.

Solution 2:

We can also solve this one of the above solutions like Replace the code block with <%# instead of <%= But the problem is it will give only relative path. If you want really absolute path it won't work.

Solution 1 works for me. Next is your choice.

To add to those who have mentioned the implicit rules, it's best to see what make has defined implicitly and for your env using:

make -p

For instance:

%.o: %.c
    $(COMPILE.c) $(OUTPUT_OPTION) $<

which expands

COMPILE.c = $(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c

This will also print # environment data. Here, you will find GCC's include path among other useful info.

C_INCLUDE_PATH=/usr/include

In make, when it comes to search, the paths are many, the light is one... or something to that effect.

1. C_INCLUDE_PATH is system-wide, set it in your shell's *.rc.
2. $(CPPFLAGS) is for the preprocessor include path.
3. If you need to add a general search path for make, use:

VPATH = my_dir_to_search

... or even more specific

vpath %.c src
vpath %.h include

make uses VPATH as a general search path so use cautiously. If a file exists in more than one location listed in VPATH, make will take the first occurrence in the list.

Use break; to escape the first loop:

if (s.Contains("mp4:production/CATCHUP/"))
{
   RemoveEXELog();
   Process p = new Process();
   p.StartInfo.WorkingDirectory = "dump";
   p.StartInfo.FileName = "test.exe"; 
   p.StartInfo.Arguments = s; 
   p.Start();
   break;
}

If you want to also escape the second loop, you might need to use a flag and check in the out loop's guard:

        boolean breakFlag = false;
        while (!breakFlag)
        {
            Thread.Sleep(5000);
            if (!System.IO.File.Exists("Command.bat")) continue;
            using (System.IO.StreamReader sr = System.IO.File.OpenText("Command.bat"))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    if (s.Contains("mp4:production/CATCHUP/"))
                    {

                        RemoveEXELog();

                        Process p = new Process();
                        p.StartInfo.WorkingDirectory = "dump";
                        p.StartInfo.FileName = "test.exe"; 
                        p.StartInfo.Arguments = s; 
                        p.Start();

                        breakFlag = true;
                        break;
                    }
                }
            }

Or, if you want to just exit the function completely from within the nested loop, put in a return; instead of a break;.

But these aren't really considered best practices. You should find some way to add the necessary Boolean logic into your while guards.

The const keyword used with the function declaration specifies that it is a const member function and it will not be able to change the data members of the object.

The common way of calculating the similarity between two strings in a 0%-100% fashion, as used in many libraries, is to measure how much (in %) you'd have to change the longer string to turn it into the shorter:

/**
 * Calculates the similarity (a number within 0 and 1) between two strings.
 */
public static double similarity(String s1, String s2) {
  String longer = s1, shorter = s2;
  if (s1.length() < s2.length()) { // longer should always have greater length
    longer = s2; shorter = s1;
  }
  int longerLength = longer.length();
  if (longerLength == 0) { return 1.0; /* both strings are zero length */ }
  return (longerLength - editDistance(longer, shorter)) / (double) longerLength;
}
// you can use StringUtils.getLevenshteinDistance() as the editDistance() function
// full copy-paste working code is below

Computing the editDistance():

The editDistance() function above is expected to calculate the edit distance between the two strings. There are several implementations to this step, each may suit a specific scenario better. The most common is the Levenshtein distance algorithm and we'll use it in our example below (for very large strings, other algorithms are likely to perform better).

Here's two options to calculate the edit distance:

• You can use Apache Commons Text's implementation of Levenshtein distance: apply(CharSequence left, CharSequence rightt)
• Implement it in your own. Below you'll find an example implementation.

Working example:

See online demo here.

public class StringSimilarity {

  /**
   * Calculates the similarity (a number within 0 and 1) between two strings.
   */
  public static double similarity(String s1, String s2) {
    String longer = s1, shorter = s2;
    if (s1.length() < s2.length()) { // longer should always have greater length
      longer = s2; shorter = s1;
    }
    int longerLength = longer.length();
    if (longerLength == 0) { return 1.0; /* both strings are zero length */ }
    /* // If you have Apache Commons Text, you can use it to calculate the edit distance:
    LevenshteinDistance levenshteinDistance = new LevenshteinDistance();
    return (longerLength - levenshteinDistance.apply(longer, shorter)) / (double) longerLength; */
    return (longerLength - editDistance(longer, shorter)) / (double) longerLength;

  }

  // Example implementation of the Levenshtein Edit Distance
  // See http://rosettacode.org/wiki/Levenshtein_distance#Java
  public static int editDistance(String s1, String s2) {
    s1 = s1.toLowerCase();
    s2 = s2.toLowerCase();

    int[] costs = new int[s2.length() + 1];
    for (int i = 0; i <= s1.length(); i++) {
      int lastValue = i;
      for (int j = 0; j <= s2.length(); j++) {
        if (i == 0)
          costs[j] = j;
        else {
          if (j > 0) {
            int newValue = costs[j - 1];
            if (s1.charAt(i - 1) != s2.charAt(j - 1))
              newValue = Math.min(Math.min(newValue, lastValue),
                  costs[j]) + 1;
            costs[j - 1] = lastValue;
            lastValue = newValue;
          }
        }
      }
      if (i > 0)
        costs[s2.length()] = lastValue;
    }
    return costs[s2.length()];
  }

  public static void printSimilarity(String s, String t) {
    System.out.println(String.format(
      "%.3f is the similarity between \"%s\" and \"%s\"", similarity(s, t), s, t));
  }

  public static void main(String[] args) {
    printSimilarity("", "");
    printSimilarity("1234567890", "1");
    printSimilarity("1234567890", "123");
    printSimilarity("1234567890", "1234567");
    printSimilarity("1234567890", "1234567890");
    printSimilarity("1234567890", "1234567980");
    printSimilarity("47/2010", "472010");
    printSimilarity("47/2010", "472011");
    printSimilarity("47/2010", "AB.CDEF");
    printSimilarity("47/2010", "4B.CDEFG");
    printSimilarity("47/2010", "AB.CDEFG");
    printSimilarity("The quick fox jumped", "The fox jumped");
    printSimilarity("The quick fox jumped", "The fox");
    printSimilarity("kitten", "sitting");
  }

}

Output:

1.000 is the similarity between "" and ""

Also a comment:

Inline styling is horrible you should avoid this at all costs, not only will it confuse you, it's poor practice.

If you want to know whether if debugging, everywhere in program. Use this.

Declare global variable.

bool isDebug=false;

Create function for checking debug mode

[ConditionalAttribute("DEBUG")]
    public static void isDebugging()
    {
        isDebug = true;
    }

In the initialize method call the function

isDebugging();

Now in the entire program. You can check for debugging and do the operations. Hope this Helps!

Your function worked for me after changing its declaration to this ...

Function processArr(Arr As Variant) As String

You could also consider a ParamArray like this ...

Function processArr(ParamArray Arr() As Variant) As String
    'Dim N As Variant
    Dim N As Long
    Dim finalStr As String
    For N = LBound(Arr) To UBound(Arr)
        finalStr = finalStr & Arr(N)
    Next N
    processArr = finalStr
End Function

And then call the function like this ...

processArr("foo", "bar")

@echo off    
del /s /f /q %windir%\temp\*.*    
rd /s /q %windir%\temp    
md %windir%\temp

All other answers may answer your query, but I faced same issue which was due to stray , which I added at the end of my json string like this:

{
 "key":"123sdf",
 "bus_number":"asd234sdf",
}

I finally got it working when I removed extra , like this:

{
 "key":"123sdf",
 "bus_number":"asd234sdf"
}

Hope this help! cheers.

As mentioned, you simply want the standard R apply function applied to columns (MARGIN=2):

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A)

Or, for short:

wifi[,4:9] <- apply(wifi[,4:9], 2, A)

This updates columns 4:9 in-place using the A() function. Now, let's assume that na.rm is an argument to A(), which it probably should be. We can pass na.rm=T to remove NA values from the computation like so:

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A, na.rm=T)

The same is true for any other arguments you want to pass to your custom function.

As of pandas 0.17.0, DataFrame.sort() is deprecated, and set to be removed in a future version of pandas. The way to sort a dataframe by its values is now is DataFrame.sort_values

As such, the answer to your question would now be

df.sort_values(['b', 'c'], ascending=[True, False], inplace=True)

If you need to switch column names you will need to create a placeholder to avoid a duplicate column name error. Here's an example:

class SwitchColumns < ActiveRecord::Migration
  def change
    rename_column :column_name, :x, :holder
    rename_column :column_name, :y, :x
    rename_column :column_name, :holder, :y
  end
end

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0
R> 

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

This regex validates dates between 01-01-2000 and 12-31-2099 with matching separators.

^(0[1-9]|1[012])([- /.])(0[1-9]|[12][0-9]|3[01])\2(19|20)\d\d$

The three best way to do it using a single line of code

X, Y = resizedLena, resizedLena

# Methode 1: Using Numpy (hstack, vstack)
Fusion_Horizontal = np.hstack((resizedLena, Y, X))
Fusion_Vertical   = np.vstack((newIMG, X))

cv2.imshow('Fusion_Vertical using vstack', Fusion_Vertical)
cv2.waitKey(0)

# Methode 2: Using Numpy (contanate)
Fusion_Vertical   = np.concatenate((resizedLena, X, Y), axis=0)
Fusion_Horizontal = np.concatenate((resizedLena, X, Y), axis=1)

cv2.imshow("Fusion_Horizontal usung concatenate", Fusion_Horizontal)
cv2.waitKey(0)


# Methode 3: Using OpenCV (vconcat, hconcat)
Fusion_Vertical   = cv2.vconcat([resizedLena, X, Y])
Fusion_Horizontal = cv2.hconcat([resizedLena, X, Y])

cv2.imshow("Fusion_Horizontal Using hconcat", Fusion_Horizontal)
cv2.waitKey(0)

You're doing a few things wrong.

1. First, browserHistory isn't a thing in V4, so you can remove that.

2. Second, you're importing everything from react-router, it should be react-router-dom.

3. Third, react-router-dom doesn't export a Router, instead, it exports a BrowserRouter so you need to import { BrowserRouter as Router } from 'react-router-dom.

Looks like you just took your V3 app and expected it to work with v4, which isn't a great idea.

The problem with interpreted languages, is that you send the source to get them working (unless you have a compiler to bytecode, but then again, it is quite trivial to decompile).

So, if you don't want to sacrifice performance, you can only act on variable and function names, eg. replacing them with a, b... aa, ab... or a101, a102, etc. And, of course, remove as much space/newlines as you can (that's what so called JS compressors do).
Obfuscating strings will have a performance hit, if you have to encrypt them and decrypt them in real time. Plus a JS debugger can show the final values...

@DRapp is a genius. I never understood how he coded his SQL,so I tried coding it in my own understanding.

    SELECT 
      f.username,
      f.point,
      f.avg_time
    FROM
      (
      SELECT
        userscores.username,
        userscores.point,
        userscores.avg_time
      FROM
        (
        SELECT
          users.username,
          scores.point,
          scores.avg_time
        FROM
          scores
        JOIN users
        ON scores.user_id = users.id
        ORDER BY scores.point DESC
        ) userscores
      ORDER BY
        point DESC,
        avg_time
      ) f
    GROUP BY f.username
    ORDER BY point DESC

It yields the same result by using GROUP BY instead of the user @variables.

well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks

i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.

I believe .clone() is what you're looking for, so long as the class supports it.

Internet Explorer 9 support MPEG4 using H.264 codec. But it also required that the file can start to play as soon as it starts downloading.

Here are the very basic steps on how to make a MPEG file that works in IE9 (using avconv on Ubuntu). I spent many hours to figure that out, so I hope that it can help someone else.

1. Convert the video to MPEG4 using H.264 codec. You don't need anything fancy, just let avconv do the job for you:

   avconv -i video.mp4 -vcodec libx264 pre_out.mp4
   

2. This video will works on all browsers that support MPEG4, except IE9. To add support for IE9, you have to move the file info to the file header, so the browser can start playing it as soon as it starts to download it. THIS IS THE KEY FOR IE9!!!

   qt-faststart pre_out.mp4 out.mp4
   

qt-faststart is a Quicktime utilities that also support H.264/ACC file format. It is part of libav-tools package.

An intent filter is an expression in an app's manifest file that specifies the type of intents that the component would like to receive.

When you create an implicit intent, the Android system finds the appropriate component to start by comparing the contents of the intent to the intent filters declared in the manifest file of other apps on the device. If the intent matches an intent filter, the system starts that component and delivers it the Intent object.

AndroidManifest.xml

<activity android:name=".HelloWorld"
    android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:scheme="http" android:host="androidium.org"/>
    </intent-filter>
</activity>

Launch HelloWorld

Intent intent = new Intent (Intent.ACTION_VIEW, Uri.parse("http://androidium.org"));
startActivity(intent);

from itertools import count, izip

def enumerate(L, n=0):
    return izip( count(n), L)

# if 2.5 has no count
def count(n=0):
    while True:
        yield n
        n+=1

Now h = list(enumerate(xrange(2000, 2005), 1)) works.

System.currentTimeMillis() does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date instance to a string before using it. You can use DateFormats to convert Dates to Strings in any timezone:

DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());

Also see this related question.

Generally, your first option (preventDefault()) is the one to take, but you have to know what context you're in and what your goals are.

PostgreSQL supports schemas, which is a subset of a database: https://www.postgresql.org/docs/current/static/ddl-schemas.html

A database contains one or more named schemas, which in turn contain tables. Schemas also contain other kinds of named objects, including data types, functions, and operators. The same object name can be used in different schemas without conflict; for example, both schema1 and myschema can contain tables named mytable. Unlike databases, schemas are not rigidly separated: a user can access objects in any of the schemas in the database they are connected to, if they have privileges to do so.

Schemas are analogous to directories at the operating system level, except that schemas cannot be nested.

In my humble opinion, MySQL is not a reference database. You should never quote MySQL for an explanation. MySQL implements non-standard SQL and sometimes claims features that it does not support. For example, in MySQL, CREATE schema will only create a DATABASE. It is truely misleading users.

This kind of vocabulary is called "MySQLism" by DBAs.

I forced closed all Java.exe from taskmanger, restarted Android Studio and it worked for me

In either ksh93 or bash with the extglob option enabled:

if [[ $var == +([0-9]) ]]; then ...

NSArray *myArray = [NSArray arrayWithObjects:[NSNumber numberWithInt:1], [NSNumber numberWithInt:2], [NSNumber numberWithInt:3]];

Update for new Objective-C syntax:

NSArray *myArray = @[@1, @2, @3];

Those two declarations are identical from the compiler's perspective.

if you're just wanting to use an integer in a string for putting into a textbox or something:

int myInteger = 5;
NSString* myNewString = [NSString stringWithFormat:@"%i", myInteger];

I agree with what Joachim Sauer said, not possible to know (the variable type! not value type!) unless your variable is a class attribute (and you would have to retrieve class fields, get the right field by name...)

Actually for me it's totally impossible that any a.xxx().yyy() method give you the right answer since the answer would be different on the exact same object, according to the context in which you call this method...

As teehoo said, if you know at compile a defined list of types to test you can use instanceof but you will also get subclasses returning true...

One possible solution would also be to inspire yourself from the implementation of java.lang.reflect.Field and create your own Field class, and then declare all your local variables as this custom Field implementation... but you'd better find another solution, i really wonder why you need the variable type, and not just the value type?

My assumption that this exception usually occurs when Tomcat is improperly closed and still holding the ports. Usually it is enough to kill any process listening to 1099 port. For Window 10:

netstat -aon | find "1099"


taskkill /F /PID $processId

I had this same problem, and resolved it by re-doing the merge using these instructions. Basically, it uses SVN's "2-URL merge" to update trunk to the current state of your branch, without bothering so much about history and tree conflicts. Saved me from manually fixing 114 tree conflicts.

I'm not sure if it preserves history as well as one would like, but it was worth it in my case.

I think that before asking how you can implement an optional protocol method, you should be asking why you should implement one.

If we think of swift protocols as an Interface in classic object oriented programming, optional methods do not make much sense, and perhaps a better solution would be to create default implementation, or separate the protocol into a set of protocols (perhaps with some inheritance relations between them) to represent the possible combination of methods in the protocol.

For further reading, see https://useyourloaf.com/blog/swift-optional-protocol-methods/, which gives an excellent overview on this matter.

Have you thought about using Python list's .index(value) method? It return the index in the list of where the first instance of the value passed in is found.

$('td:first-child') will return a collection of the elements that you want.

var text = $('td:first-child').map(function() {
  return $(this).html();
}).get();

You can use above function for casting not similar class objects (PHP >= 5.3)

/**
 * Class casting
 *
 * @param string|object $destination
 * @param object $sourceObject
 * @return object
 */
function cast($destination, $sourceObject)
{
    if (is_string($destination)) {
        $destination = new $destination();
    }
    $sourceReflection = new ReflectionObject($sourceObject);
    $destinationReflection = new ReflectionObject($destination);
    $sourceProperties = $sourceReflection->getProperties();
    foreach ($sourceProperties as $sourceProperty) {
        $sourceProperty->setAccessible(true);
        $name = $sourceProperty->getName();
        $value = $sourceProperty->getValue($sourceObject);
        if ($destinationReflection->hasProperty($name)) {
            $propDest = $destinationReflection->getProperty($name);
            $propDest->setAccessible(true);
            $propDest->setValue($destination,$value);
        } else {
            $destination->$name = $value;
        }
    }
    return $destination;
}

EXAMPLE:

class A 
{
  private $_x;   
}

class B 
{
  public $_x;   
}

$a = new A();
$b = new B();

$x = cast('A',$b);
$x = cast('B',$a);

In order of preference:

1. If you are using a templating engine (e.g. Twig, Smarty, Blade), check that it offers context-sensitive escaping. I know from experience that Twig does. {{ var|e('html_attr') }}
2. If you want to allow HTML, use HTML Purifier. Even if you think you only accept Markdown or ReStructuredText, you still want to purify the HTML these markup languages output.
3. Otherwise, use htmlentities($var, ENT_QUOTES | ENT_HTML5, $charset) and make sure the rest of your document uses the same character set as $charset. In most cases, 'UTF-8' is the desired character set.

Also, make sure you escape on output, not on input.

In previous posts I have read that this feature IS available on VS 2015 community if you FIRST install SQL Server express (free) and THEN install VS. I have tried it and it worked. I just had to reinstall Windows and am going thru the same procedure now and it did not work... so will try again :). I know it worked 6 months ago when I tried.

-Ed

I was thundered when the following code worked.

import os

for file in os.listdir("../FutureBookList"):
    if file.endswith(".adoc"):
        filename, file_extension = os.path.splitext(file)
        print(filename)
        print(file_extension)
        continue
    else:
        continue

So, I checked the documentation and it says:

Changed in version 3.6: Accepts a path-like object.

path-like object:

An object representing a file system path. A path-like object is either a str or...

I did a little more digging and the following also works:

with open("../FutureBookList/file.txt") as file:
   data = file.read()

Can you put the comparision code you posted into some static utility method?

public static String findDifference(Type obj1, Type obj2) {
    String difference = "";
    if (obj1.getFieldA() == null && obj2.getFieldA() != null
            || !obj1.getFieldA().equals(obj2.getFieldA())) {
        difference += "Difference at field A:" + "obj1 - "
                + obj1.getFieldA() + ", obj2 - " + obj2.getFieldA();
    }
    if (obj1.getFieldB() == null && obj2.getFieldB() != null
            || !obj1.getFieldB().equals(obj2.getFieldB())) {
        difference += "Difference at field B:" + "obj1 - "
                + obj1.getFieldB() + ", obj2 - " + obj2.getFieldB();
        // (...)
    }
    return difference;
}

Than you can use this method in JUnit like this:

assertEquals("Objects aren't equal", "", findDifferences(obj1, obj));

which isn't clunky and gives you full information about differences, if they exist (through not exactly in normal form of assertEqual but you get all the info so it should be good).

You don't have the last version of typescript.

Running :

npm install -g typescript

npm checks if tsc command is already installed.

And it might be, by another software like Visual Studio. If so, npm doesn't override it. So you have to remove the previous deprecated tsc installed command.

Run where tsc to know its bin location. It should be in C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\ in windows. Once found, delete the folder, and re-run npm install -g typescript. This should now install the last version of typescript.

Write the function inline, and the interpreter is smart enough to know you're writing a function. Do it like this, and it assumes it's just a string (which it technically is).

Nowdays, there is a new technique suggested by google to cache and improve your image rendering process:

1. Include the JavaScript Lazysizes file: lazysizes.js
2. Add the file to the html file you want to use in: <script src="lazysizes.min.js" async></script>
3. Add the lazyload class to your image: <img data-src="images/flower3.png" class="lazyload" alt="">

If it happens in Chrome version > 45.x,

(1) try: System | Settings | Advanced settings
     uncheck "Use hardware acceleration when available", restart chrome.

(2) If (1) doesn't help, restart your computer

(3) If the black screen still occurs, try Chrome Cleanup Tool to reset your chrome.

As quick n dirty fix, this worked for me: Adding this 2 lines before the problematic import:

import sys
sys.path.append('C:\\Python27\\Lib\site-packages')

I wasn't going to answer this question but there are two answers here (that are getting voted up!) that are just plain wrong. Consider these expressions:

String a = "a" + "b" + "c";
String b = System.getProperty("blah") + "b";

The first is evaluated at compile-time. The second is evaluated at run-time.

So never replace constant concatenations (of any type) with StringBuilder, StringBuffer or the like. Only use those where variables are invovled and generally only when you're appending a lot of operands or you're appending in a loop.

If the characters are constant, this is fine:

String s = "" + 'a' + 'b' + 'c';

If however they aren't, consider this:

String concat(char... chars) {
  if (chars.length == 0) {
    return "";
  }
  StringBuilder s = new StringBuilder(chars.length);
  for (char c : chars) {
    s.append(c);
  }
  return s.toString();
}

as an appropriate solution.

However some might be tempted to optimise:

String s = "Name: '" + name + "'"; // String name;

into this:

String s = new StringBuilder().append("Name: ").append(name).append("'").toString();

While this is well-intentioned, the bottom line is DON'T.

Why? As another answer correctly pointed out: the compiler does this for you. So in doing it yourself, you're not allowing the compiler to optimise the code or not depending if its a good idea, the code is harder to read and its unnecessarily complicated.

For low-level optimisation the compiler is better at optimising code than you are.

Let the compiler do its job. In this case the worst case scenario is that the compiler implicitly changes your code to exactly what you wrote. Concatenating 2-3 Strings might be more efficient than constructing a StringBuilder so it might be better to leave it as is. The compiler knows whats best in this regard.

This is a Task that is returning a Task of type String (C# anonymous function or in other word a delegation is used 'Func')

    public static async Task<string> MyTask()
    {
        //C# anonymous AsyncTask
        return await Task.FromResult<string>(((Func<string>)(() =>
        {
            // your code here
            return  "string result here";

        }))());
    }

I know this post is a few years old, but what I do is add this line to the top of your class and you will still be able to user Server.MapPath

Dim Server = HttpContext.Current.Server

or u can make a function

Public Function MapPath(sPath as String)
    return HttpContext.Current.Server.MapPath(sPath)
End Function

I am all about making things easier. I have also added it to my Utilities class just in case i run into this again.

I'm on a roll, just found an even simpler way to do it using the by keyword in the hist method:

df['N'].hist(by=df['Letter'])

That's a very handy little shortcut for quickly scanning your grouped data!

For future visitors, the product of this call is the following chart:

I had another bug where find_link on Chrome and Poltergeist could not click an A tag with an EM tag and some text inside of it, although it worked fine in Firefox and rack_test. The solution was to replace click_link(link) with:

find('a em', text: link).click

If you have already installed all your dependencies, and you want to avoid having to download your production packages from NPM again, you can simply type:

npm prune --production

This will remove your dev dependencies from your node_modules folder, which is helpful if you're trying to automate a two step process like

1. Webpack my project, using dev dependencies
2. Build a Docker image using only production modules

Running npm prune in between will save you from having to reinstall everything!

With the caveat of it not working in IE and some older mobile browsers, a simple object-fit: cover; is often the best option.

.cropper {
  position: relative;
  width: 100px;
  height: 100px;
  overflow: hidden;
}
.cropper img {
  position: absolute;
  width: 100%;
  height: 100%;
  object-fit: cover;
}

Without the object-fit: cover support, the image will be stretched oddly to fit the box so, if support for IE is needed, I'd recommend using one of the other answers' approach with -100% top, left, right and bottom values as a fallback.

Try something like this...

<div id="wrapper" style="width:100%; text-align:center">
<img id="yourimage"/>
</div>

Use a duplicated double quote.

@"this ""word"" is escaped";

outputs:

this "word" is escaped

Checkout your laravel/framework version on your composer.json file,

If it's either "^6.0" or higher than "^5.9",

you have to use php artisan ui:auth instead of php artisan make:auth.

Before using that you have to install new dependencies by calling composer require laravel/ui --dev in the current directory.

Have a look at CONVERT. The 3rd parameter is the date time style you want to convert to.

e.g.

SELECT CONVERT(VARCHAR(10), GETDATE(), 103) -- dd/MM/yyyy format

it is simple just use .qsize() example:

a=Queue()
a.put("abcdef")
print a.qsize() #prints 1 which is the size of queue

The above snippet applies for Queue() class of python. Thanks @rayryeng for the update.

for deque from collections we can use len() as stated here by K Z.

Regarding the internal structure of a Python long, check sys.int_info (or sys.long_info for Python 2.7).

>>> import sys
>>> sys.int_info
sys.int_info(bits_per_digit=30, sizeof_digit=4)

Python either stores 30 bits into 4 bytes (most 64-bit systems) or 15 bits into 2 bytes (most 32-bit systems). Comparing the actual memory usage with calculated values, I get

>>> import math, sys
>>> a=0
>>> sys.getsizeof(a)
24
>>> a=2**100
>>> sys.getsizeof(a)
40
>>> a=2**1000
>>> sys.getsizeof(a)
160
>>> 24+4*math.ceil(100/30)
40
>>> 24+4*math.ceil(1000/30)
160

There are 24 bytes of overhead for 0 since no bits are stored. The memory requirements for larger values matches the calculated values.

If your numbers are so large that you are concerned about the 6.25% unused bits, you should probably look at the gmpy2 library. The internal representation uses all available bits and computations are significantly faster for large values (say, greater than 100 digits).

This seems to provide the info on Windows:

1.) Open a windows command prompt.

2.) Key in: java -XshowSettings:all and hit ENTER.

3.) A lot of information will be displayed on the command window. Scroll up until you find the string: sun.arch.data.model.

4.) If it says sun.arch.data.model = 32, your VM is 32 bit. If it says sun.arch.data.model = 64, your VM is 64 bit.

This might be handy for anyone who needs to an exception for both 'www' and 'non-www' versions of a referrer:

 $referrer = $_SERVER['HTTP_REFERER'];
 $parts = parse_url($referrer);
 $domain = $parts['host'];

 if($domain == 'google.com')
 {
         header('Access-Control-Allow-Origin: http://google.com');
 }
 else if($domain == 'www.google.com')
 {
         header('Access-Control-Allow-Origin: http://www.google.com');
 }

I am using docker-compose to build the Kafka container using wurstmeister/kafka image. Adding KAFKA_ADVERTISED_PORT: 9092 property to my docker-compose file solved this error for me.

open() is a low-level os call. fdopen() converts an os-level file descriptor to the higher-level FILE-abstraction of the C language. fopen() calls open() in the background and gives you a FILE-pointer directly.

There are several advantages to using FILE-objects rather raw file descriptors, which includes greater ease of usage but also other technical advantages such as built-in buffering. Especially the buffering generally results in a sizeable performance advantage.

Someone's going to post a much better answer than this, but just wanted to make the point that personally I would never store a phone number in any kind of integer field, mainly because:

1. You don't need to do any kind of arithmetic with it, and
2. Sooner or later someone's going to try to (do something like) put brackets around their area code.

In general though, I seem to almost exclusively use:

• INT(11) for anything that is either an ID or references another ID
• DATETIME for time stamps
• VARCHAR(255) for anything guaranteed to be under 255 characters (page titles, names, etc)
• TEXT for pretty much everything else.

Of course there are exceptions, but I find that covers most eventualities.

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

Everybody seems to be suggesting that adding

using System.Configuration;

which is true.

But might I suggest that you think about installing ReSharper's Visual Studio extension?

With it installed, instead of seeing an error that a class isn't defined, you'll see a prompt that tells you which assembly it is in, asking you if you want it to add the needed using statement.

Money transfered online form one account to another account is stateful, because the receving account has information about the sender. Handing over cash from a person to another person, this transaction is statless, because after cash is recived the identity of the giver is not there with the cash.

You can now, using React hooks

Using react hooks, you can now call useState() in your function component.

useState() will return an array of 2 things:

1. A value, representing the current state.
2. Its setter. Use it to update the value.

Updating the value by its setter will force your function component to re-render,
just like forceUpdate does:

import React, { useState } from 'react';

//create your forceUpdate hook
function useForceUpdate(){
    const [value, setValue] = useState(0); // integer state
    return () => setValue(value => value + 1); // update the state to force render
}

function MyComponent() {
    // call your hook here
    const forceUpdate = useForceUpdate();
    
    return (
        <div>
            {/*Clicking on the button will force to re-render like force update does */}
            <button onClick={forceUpdate}>
                Click to re-render
            </button>
        </div>
    );
}

You can find a demo here.

The component above uses a custom hook function (useForceUpdate) which uses the react state hook useState. It increments the component's state's value and thus tells React to re-render the component.

EDIT

In an old version of this answer, the snippet used a boolean value, and toggled it in forceUpdate(). Now that I've edited my answer, the snippet use a number rather than a boolean.

Why ? (you would ask me)

Because once it happened to me that my forceUpdate() was called twice subsequently from 2 different events, and thus it was reseting the boolean value at its original state, and the component never rendered.

This is because in the useState's setter (setValue here), React compare the previous state with the new one, and render only if the state is different.

If you are using jQuery you can do this:

$(function() {_x000D_
_x000D_
  var $list = $("#list");_x000D_
_x000D_
  $list.children().detach().sort(function(a, b) {_x000D_
    return $(a).text().localeCompare($(b).text());_x000D_
  }).appendTo($list);_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<ul id="list">_x000D_
  <li>delta</li>_x000D_
  <li>cat</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>beta</li>_x000D_
  <li>gamma</li>_x000D_
  <li>gamma</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>delta</li>_x000D_
  <li>bat</li>_x000D_
  <li>cat</li>_x000D_
</ul>

Note that returning 1 and -1 (or 0 and 1) from the compare function is absolutely wrong.

At work we have a common library that is used by a few different projects all in a single repository. Originally we used the published (private) version (npm install --save rp-utils) but that lead to a lot of needless version updates as we developed. The library lives in a sister directory to the applications and we are able to use a relative path instead of a version. Instead of "rp-utils": "^1.3.34" in package.json it now is:

{ 
  "dependencies": { ...
    "rp-utils": "../rp-utils",
   ...

the rp-utils directory contains a publishable npm package

Here's your model (with invented CT and TE) using protobuf-net (yet retaining the ability to use XmlSerializer, which can be useful - in particular for migration); I humbly submit (with lots of evidence if you need it) that this is the fastest (or certainly one of the fastest) general purpose serializer in .NET.

If you need strings, just base-64 encode the binary.

[XmlType]
public class CT {
    [XmlElement(Order = 1)]
    public int Foo { get; set; }
}
[XmlType]
public class TE {
    [XmlElement(Order = 1)]
    public int Bar { get; set; }
}
[XmlType]
public class TD {
    [XmlElement(Order=1)]
    public List<CT> CTs { get; set; }
    [XmlElement(Order=2)]
    public List<TE> TEs { get; set; }
    [XmlElement(Order = 3)]
    public string Code { get; set; }
    [XmlElement(Order = 4)]
    public string Message { get; set; }
    [XmlElement(Order = 5)]

        using (var ms = new MemoryStream()) {
            ProtoBuf.Serializer.Serialize(ms, tData);
            return ms.ToArray();
        }            
    }

    public static List<TD> Deserialize(byte[] tData) {
        using (var ms = new MemoryStream(tData)) {

If you want downloads number for each customer, use:

select ssn
     , sum(time)
  from downloads
 group by ssn

If you want just one record -- for a customer with highest number of downloads -- use:

select *
  from (
        select ssn
             , sum(time)
          from downloads
         group by ssn
         order by sum(time) desc
       )
 where rownum = 1

However if you want to see all customers with the same number of downloads, which share the highest position, use:

select *
  from (
        select ssn
             , sum(time)
             , dense_rank() over (order by sum(time) desc) r
          from downloads
         group by ssn
       )
 where r = 1

Query information_schema.columns directly:

select * from information_schema.columns 
where table_name = 'your_table' and table_schema = 'your_database'

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

You need to change source to viewmodel object:

myBinding.Source = viewModelObject;

What about something like this?

<?php
$URL = "http://example.com";
$base = '<base href="'.$URL.'">';
$host = preg_replace('/^[^\/]+\/\//', '', $URL);
$tarray = explode('/', $host);
$host = array_shift($tarray);
$URI = '/' . implode('/', $tarray);
$content = '';
$fp = @fsockopen($host, 80, $errno, $errstr, 30);
if(!$fp) { echo "Unable to open socked: $errstr ($errno)\n"; exit; } 
fwrite($fp,"GET $URI HTTP/1.0\r\n");
fwrite($fp,"Host: $host\r\n");
if( isset($_SERVER["HTTP_USER_AGENT"]) ) { fwrite($fp,'User-Agent: '.$_SERVER

["HTTP_USER_AGENT"]."\r\n"); }
fwrite($fp,"Connection: Close\r\n");
fwrite($fp,"\r\n");
while (!feof($fp)) { $content .= fgets($fp, 128); }
fclose($fp);
if( strpos($content,"\r\n") > 0 ) { $eolchar = "\r\n"; }
else { $eolchar = "\n"; }
$eolpos = strpos($content,"$eolchar$eolchar");
$content = substr($content,($eolpos + strlen("$eolchar$eolchar")));
if( preg_match('/<head\s*>/i',$content) ) { echo( preg_replace('/<head\s*>/i','<head>'.

$base,$content,1) ); }
else { echo( preg_replace('/<([a-z])([^>]+)>/i',"<\\1\\2>".$base,$content,1) ); }
?>

On linux, clock_gettime() is one of the good choices. You must link real time library(-lrt).

Search for "Objective-C Generated Interface Header Name" in the Build Settings of the target you're trying to build (let's say it's MyApp-Swift.h), and import the value of this setting (#import "MyApp-Swift.h") in the source file where you're trying to access your Swift APIs.

The default value for this field is $(SWIFT_MODULE_NAME)-Swift.h. You can see it if you double-click in the value field of the "Objective-C Generated Interface Header Name" setting.

Also, if you have dashes in your module name (let's say it's My-App), then in the $(SWIFT_MODULE_NAME) all dashes will be replaced with underscores. So then you'll have to add #import "My_App-Swift.h".

One other option is to use a plyr function:

df <- ldply(listOfDataFrames, data.frame)

This is a little slower than the original:

> system.time({ df <- do.call("rbind", listOfDataFrames) })
   user  system elapsed 
   0.25    0.00    0.25 
> system.time({ df2 <- ldply(listOfDataFrames, data.frame) })
   user  system elapsed 
   0.30    0.00    0.29
> identical(df, df2)
[1] TRUE

My guess is that using do.call("rbind", ...) is going to be the fastest approach that you will find unless you can do something like (a) use a matrices instead of a data.frames and (b) preallocate the final matrix and assign to it rather than growing it.

Edit 1:

Based on Hadley's comment, here's the latest version of rbind.fill from CRAN:

> system.time({ df3 <- rbind.fill(listOfDataFrames) })
   user  system elapsed 
   0.24    0.00    0.23 
> identical(df, df3)
[1] TRUE

This is easier than rbind, and marginally faster (these timings hold up over multiple runs). And as far as I understand it, the version of plyr on github is even faster than this.

I had the same problem and I prefer not to replace the entire ArrayAdapter with a new instance continuously. Thus I have the AdapterHelper do the heavy lifting somewhere else.

Add this where you would normally (try to) call notify

new AdapterHelper().update((ArrayAdapter)adapter, new ArrayList<Object>(yourArrayList));
adapter.notifyDataSetChanged();

AdapterHelper class

public class AdapterHelper {
    @SuppressWarnings({ "rawtypes", "unchecked" })
    public void update(ArrayAdapter arrayAdapter, ArrayList<Object> listOfObject){
        arrayAdapter.clear();
        for (Object object : listOfObject){
            arrayAdapter.add(object);
        }
    }
}

I put together a quick solution for anyone wanting to create hover popups without CSS using the onmouseover and onmouseout behaviors.

http://jsfiddle.net/Lk9w1mkv/

<div style="position:relative;width:100px;background:#ddffdd;overflow:hidden;" onmouseover="this.style.overflow='';" onmouseout="this.style.overflow='hidden';">first hover<div style="width:100px;position:absolute;top:5px;left:110px;background:white;border:1px solid gray;">stuff inside</div></div>

By default, gulp runs tasks simultaneously, unless they have explicit dependencies. This isn't very useful for tasks like clean, where you don't want to depend, but you need them to run before everything else.

I wrote the run-sequence plugin specifically to fix this issue with gulp. After you install it, use it like this:

var runSequence = require('run-sequence');

gulp.task('develop', function(done) {
    runSequence('clean', 'coffee', function() {
        console.log('Run something else');
        done();
    });
});

You can read the full instructions on the package README — it also supports running some sets of tasks simultaneously.

Please note, this will be (effectively) fixed in the next major release of gulp, as they are completely eliminating the automatic dependency ordering, and providing tools similar to run-sequence to allow you to manually specify run order how you want.

However, that is a major breaking change, so there's no reason to wait when you can use run-sequence today.

if you invoke .equals() on null you will get NullPointerException

So it is always advisble to check nullity before invoking method where ever it applies

if(str!=null && str.equals("hi")){
 //str contains hi
}

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

$cfg['Servers'][$i]['AllowNoPassword'] = false;

I had received a similar error message. Think I inadvertently typed "9o" at start of first line of php.ini file. Once I removed that, I no longer received the "fatal error" messages. Hope this helps.

There is additionally collections’ stream() util with Java 8

collection.forEach((temp) -> {
            System.out.println(temp);
});

or

collection.forEach(System.out::println);

So, you essentially want to delete multiple elements in one pass? In that case, the position of the next element to delete will be offset by however many were deleted previously.

Our goal is to delete all the vowels, which are precomputed to be indices 1, 4, and 7. Note that its important the to_delete indices are in ascending order, otherwise it won't work.

to_delete = [1, 4, 7]
target = list("hello world")
for offset, index in enumerate(to_delete):
  index -= offset
  del target[index]

It'd be a more complicated if you wanted to delete the elements in any order. IMO, sorting to_delete might be easier than figuring out when you should or shouldn't subtract from index.

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

None of these worked for me. It started happening after a chrome update (Version 63.0.3239.84, linux) with a local URL. Would always redirect to https no matter what. Lost some hours and a lot of patience on this

What did worked after all was just changing the domain.

For what is worth, the domain was .app. Perhaps it got something to do? And just changed it to .test and chrome stopped redirecting it

An elegant way to count the occurrence of '?' or any symbol in any column, is to use built-in function isin of a dataframe object.

Suppose that we have loaded the 'Automobile' dataset into df object. We do not know which columns contain missing value ('?' symbol), so let do:

df.isin(['?']).sum(axis=0)

DataFrame.isin(values) official document says:

it returns boolean DataFrame showing whether each element in the DataFrame is contained in values

Note that isin accepts an iterable as input, thus we need to pass a list containing the target symbol to this function. df.isin(['?']) will return a boolean dataframe as follows.

    symboling   normalized-losses   make    fuel-type   aspiration-ratio ...
0   False       True                False   False       False
1   False       True                False   False       False
2   False       True                False   False       False
3   False       False               False   False       False
4   False       False               False   False       False
5   False       True                False   False       False
...

To count the number of occurrence of the target symbol in each column, let's take sum over all the rows of the above dataframe by indicating axis=0. The final (truncated) result shows what we expect:

symboling             0
normalized-losses    41
...
bore                  4
stroke                4
compression-ratio     0
horsepower            2
peak-rpm              2
city-mpg              0
highway-mpg           0
price                 4

use the str_replace function to replace them with empty space or something

$query = '<script>console.log("I should be banned")</script>';

$badChar = array('<script>','</script>');
$query = str_replace($badChar, '', $query);

echo $query; 
//this echoes console.log("I should be banned")

?>

my 2-cents:

import sys, traceback
try: 
  ...
except Exception, e:
  T, V, TB = sys.exc_info()
  print ''.join(traceback.format_exception(T,V,TB))

Have you tried using the generic DeserializeObject method?

JsonConvert.DeserializeObject<MyAccount>(myjsondata);

Any missing fields in the JSON data should simply be left NULL.

UPDATE:

If the JSON string is an array, try this:

var jarray = JsonConvert.DeserializeObject<List<MyAccount>>(myjsondata);

jarray should then be a List<MyAccount>.

ANOTHER UPDATE:

The exception you're getting isn't consistent with an array of objects- I think the serializer is having problems with your Dictionary-typed accountstatusmodifiedby property.

Try excluding the accountstatusmodifiedby property from the serialization and see if that helps. If it does, you may need to represent that property differently.

the following is that the difference between iterator and listIterator

iterator :

boolean hasNext();
E next();
void remove();

listIterator:

boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove();
void set(E e);
void add(E e);

I am in the same boot like you. In the case you mention, I would implement the input validation UI component as a React component.

I agree the implementation of the validation logic itself should (must) not be coupled. Therefore I would put it into a separate JS module.

That is, for logic that should not be coupled use a JS module/class in separate file, and use require/import to de-couple the component from the "service".

This allows for dependency injection and unit testing of the two independently.

df.aree <- as.data.frame(t(df.aree))
colnames(df.aree) <- df.aree[1, ]
df.aree <- df.aree[-1, ]
df.aree$myfactor <- factor(row.names(df.aree))

Just as simple as this:

$("#myElem").show("slow").delay(5000).hide("slow");

I think you can use Padding like: Hope this one can help you.

.loginButton {
    background:url(images/loginBtn-center.jpg) repeat-x;
    width:175px;
    height:65px;
    margin:20px auto;
    border-radius:10px;
    -webkit-border-radius:10px;
    box-shadow:0 1px 2px #5e5d5b;
    <!--Using padding to align text in box or image-->
    padding: 3px 2px;
}

This works:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

I just wanted to chime in that I hit this after updating Android Studio components.

What worked for me was to open gradle-wrapper.properties and update the gradle version used. As of now for my projects the line reads:
