In case anyone else stumbles across this question, this is probably what you were looking for:

.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

 /* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}

Just to include the latest update (UPDATE 4) in @Arhimed 's immaculate answer in the very good summary of @sulai:

void doTheTask(AsyncTask task) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { // Android 4.4 (API 19) and above
        // Parallel AsyncTasks are possible, with the thread-pool size dependent on device
        // hardware
        task.execute(params);
    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { // Android 3.0 to
        // Android 4.3
        // Parallel AsyncTasks are not possible unless using executeOnExecutor
        task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
    } else { // Below Android 3.0
        // Parallel AsyncTasks are possible, with fixed thread-pool size
        task.execute(params);
    }
}

If you want to kill the Sticky Service,the following command NOT WORKING:

adb shell am force-stop <PACKAGE>
adb shell kill <PID>

The following command is WORKING:

adb shell pm disable <PACKAGE>

If you want to restart the app,you must run command below first:

adb shell pm enable <PACKAGE>

An easier and shorter way is:

 <input type="text" class="form-control" data-ng-model="searchAll">
 <a class="clear" data-ng-click="searchAll = '' ">X</a>

This has always worked for me.

I was just faced with a similar problem. I exported the contents of the db into one sql file and used TextEdit to find and replace everything I needed. Simplicity ftw!

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

Define the query method with signatures as follows.

@Query(select p from Person p where p.forename = :forename and p.surname = :surname)
User findByForenameAndSurname(@Param("surname") String lastname,
                             @Param("forename") String firstname);
}

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

This is working on Flowplayer 6.0.2.

<script>
    flowplayer().load({
         sources: [
            { type: "video/mp4",  src: variable }
            ]
        });
</script>

where variable is a javascript/jquery variable value, The video tag should be something this

<div class="flowplayer">
   <video>
      <source type="video/mp4" src="" class="videomp4">
   </video>
</div>

Hope it helps anyone.

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

Note that if you want to comment out a single line of printing erb you should do like this

<%#= ["Buck", "Papandreou"].join(" you ") %>

CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.

I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.

Google has open sourced its excellent PDF rendering engine - PDFium - that it wrote with Foxit Software.

There is a C# nuget package called PdfiumViewer which gives a C# wrapper around PDFium and allows PDFs to be displayed and printed.

I have used it and was very impressed with the quality of the rendering.

PDFium works directly with streams so it doesn't require any data to be written to disk.

This is my example from a WinForms app

    public void LoadPdf(byte[] pdfBytes)
    {
        var stream = new MemoryStream(pdfBytes);
        LoadPdf(stream)
    }

    public void LoadPdf(Stream stream)
    {
        // Create PDF Document
        var pdfDocument = PdfDocument.Load(stream);

        // Load PDF Document into WinForms Control
        pdfRenderer.Load(pdfDocument);
    }

Edit: To get the pdfRenderer control in WinForm: Add the PdfiumViewer NuGet package to the project; open the projects packages folder in Windows Explorer and drag the PdfiumViewer.dll file onto the Toolbox window; A control called PdfRenderer will be available to add:

Here how to do this on mongodb 3.0. I used this nice blog

1. Install mongodb.
2. Create data directories:

$ mkdir RANDOM_PATH/node1
$ mkdir RANDOM_PATH/node2> 
$ mkdir RANDOM_PATH/node3

3. Start Mongod instances

$ mongod --replSet test --port 27021 --dbpath node1
$ mongod --replSet test --port 27022 --dbpath node2
$ mongod --replSet test --port 27023 --dbpath node3

4. Configure the Replica Set:

$ mongo
config = {_id: 'test', members: [ {_id: 0, host: 'localhost:27021'}, {_id: 1, host: 'localhost:27022'}]};    
rs.initiate(config);

5. Installing Elasticsearch:

a. Download and unzip the [latest Elasticsearch][2] distribution

b. Run bin/elasticsearch to start the es server.

c. Run curl -XGET http://localhost:9200/ to confirm it is working.

6. Installing and configuring the MongoDB River:

$ bin/plugin --install com.github.richardwilly98.elasticsearch/elasticsearch-river-mongodb

$ bin/plugin --install elasticsearch/elasticsearch-mapper-attachments

7. Create the “River” and the Index:

curl -XPUT 'http://localhost:8080/_river/mongodb/_meta' -d '{ "type": "mongodb", "mongodb": { "db": "mydb", "collection": "foo" }, "index": { "name": "name", "type": "random" } }'

8. Test on browser:

   http://localhost:9200/_search?q=home

Assuming that you're on SQL Server 2005 or greater, you can use a CTE with ROW_NUMBER():

SELECT  *
FROM    (SELECT ID, SKU, Product,
                ROW_NUMBER() OVER (PARTITION BY PRODUCT ORDER BY ID) AS RowNumber
         FROM   MyTable
         WHERE  SKU LIKE 'FOO%') AS a
WHERE   a.RowNumber = 1

in your setting.py file replace DIRS in TEMPLATES array with this

'DIRS': []

to this

'DIRS': [os.path.join(BASE_DIR, 'templates')],

but 1 think u need to know is that you have to make a folder with name templates and it should on the root path otherwise u have to change the DIRS value

Below function can be used to check for a value in any level in a JSON

function _isContains(json, value) {
    let contains = false;
    Object.keys(json).some(key => {
        contains = typeof json[key] === 'object' ? _isContains(json[key], value) : json[key] === value;
         return contains;
    });
    return contains;
 }

then to check if JSON contains the value

_isContains(JSONObject, "dog")

See this fiddle: https://jsfiddle.net/ponmudi/uykaacLw/

Most of the answers mentioned here compares by 'name' key. But no need to care about the key, can just checks if JSON contains the given value. So that the function can be used to find any value irrespective of the key.

I had the same problem, and found a detailed explanation in http://www.webmasterworld.com/apache/3163397.htm

My solution (the subdomains contents should be in a folder called sd_subdomain:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} subdomain\.domain\.com
RewriteCond $1 !^sd_
RewriteRule (.*) /sd_subdomain/$1 [L]

It's not the angular way, remove the function from html body and use it in controller, or use

angular.element(document).ready

More details are available here: https://stackoverflow.com/a/18646795/4301583

in windows command Type command blow:

taskkill /f /im node.exe

+1 for doing hover and click both. One other way could be using CSS media queries and using some styles only for smaller screens / mobile devices, which are the ones most likely to have touch / tap functionality. So if you have some specific styles via CSS, and from jQuery you check those elements for the mobile device style properties you could hook into them to write you mobile specific code.

See here: http://www.forabeautifulweb.com/blog/about/hardboiled_css3_media_queries/

This is as close as I can get to the natural feel of Python's "in" operator. You have to define your own type. Then you can extend the functionality of that type by adding a method like "has" which behaves like you'd hope.

package main

import "fmt"

type StrSlice []string

func (list StrSlice) Has(a string) bool {
    for _, b := range list {
        if b == a {
            return true
        }
    }
    return false
}

func main() {
    var testList = StrSlice{"The", "big", "dog", "has", "fleas"}

    if testList.Has("dog") {
        fmt.Println("Yay!")
    }
}

I have a utility library where I define a few common things like this for several types of slices, like those containing integers or my own other structs.

Yes, it runs in linear time, but that's not the point. The point is to ask and learn what common language constructs Go has and doesn't have. It's a good exercise. Whether this answer is silly or useful is up to the reader.

i dont know if the full resolution has been made for this yet. i know that from doing a 2 column page with fixed left side bar, to get a contact us form centered on my page i put the following:

    form {
 width: 100%;
 margin-left: auto;
 margin-right: auto;
 display: inline-block;
 }

this worked for me so thought id throw in my resolution to the same problem

ansible your_server_name -i custom_inventory_file_name -m -a "uptime"

The default module is command module, hence command keyword is not required.

If you need to issue any command with elevated privileges use -b at the end of the same command.

ansible your_server_name -i custom_inventory_file_name -m -a "uptime" -b

This image gives the answer. Please read it.

This is an old question but alot of the answers in here use VB or VBA. The tag says vbscript (which is how I got here).

The answers here got kind of muddled since VB is super broad where you can have so many applications of it. My answer is solely on vbscript and accomplishes my case of formatting in YYYYMMDD in vbscript

Sharing what I've learned:

1. There are all the DateTime functions in vbscript defined here so you can mix-n-match to get the result that you want
2. What I needed was to get the current date and format it in YYYYMMDD to do that I just needed to concat DatePart like so for the current Date: date = DatePart("yyyy",Date) & DatePart("m",Date) & DatePart("d",Date)

That's all, I hope this helps someone.

To just print 1 or 0 based on the boolean value I just used:

printf("%d\n", !!(42));

Especially useful with Flags:

#define MY_FLAG (1 << 4)
int flags = MY_FLAG;
printf("%d\n", !!(flags & MY_FLAG));

@Nazar Medeiros - Your solution uses passport with Express. I am not using passport, just express-jwt. I might be doing something wrong, but when a user logs in, the token needs to return to the client side. From what I have found so far, this means we have to return a json with the token and therefor cannot call redirect. Is there something I am missing there?

To get around this, I simply return the token, store it in my cookies and then make a ajax GET request (with the valid token). When that ajax call returns I replace the body's html with the returned HTML. This is probably not the right way to do it, but I can't find a better way. Here is my JQuery JavaScript code.

function loginUser(){
  $.post("/users/login", {
    username: $( '#login_input_username' ).val(),
   password: $( '#login_input_password' ).val()
 }).done(function(res){
    document.cookie = "token = " + res.token;
    redirectToHome();
  })
}

function redirectToHome(){
  var settings = {
    "async": true,
    "crossDomain": true,
    "url": "/home",
    "type": "GET",
    "headers": {
      "authorization": "Bearer " + getCookie('token'),
      "cache-control": "no-cache"
    }
  }

  $.ajax(settings).done(function (response) {
    $('body').replaceWith(response);
  });
}

function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    for(var i = 0; i <ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

Even easier!

strings contains myString

First of all - prerequisite for downcast is that object you are casting is of the type you are casting to. Casting with dynamic_cast will check this condition in runtime (provided that casted object has some virtual functions) and throw bad_cast or return NULL pointer on failure. Compile-time casts will not check anything and will just lead tu undefined behaviour if this prerequisite does not hold.
Now analyzing your code:

DerivedType m_derivedType = m_baseType;

Here there is no casting. You are creating a new object of type DerivedType and try to initialize it with value of m_baseType variable.

Next line is not much better:

DerivedType m_derivedType = (DerivedType)m_baseType;

Here you are creating a temporary of DerivedType type initialized with m_baseType value.

The last line

DerivedType * m_derivedType = (DerivedType*) & m_baseType;

should compile provided that BaseType is a direct or indirect public base class of DerivedType. It has two flaws anyway:

1. You use deprecated C-style cast. The proper way for such casts is
   static_cast<DerivedType *>(&m_baseType)
2. The actual type of casted object is not of DerivedType (as it was defined as BaseType m_baseType; so any use of m_derivedType pointer will result in undefined behaviour.

Sure the code does work, but I'm pretty sure it doesn't do what you expect it to do. It just fires off multiple asynchronous calls, but the printFiles function does immediately return after that.

Reading in sequence

If you want to read the files in sequence, you cannot use forEach indeed. Just use a modern for … of loop instead, in which await will work as expected:

async function printFiles () {
  const files = await getFilePaths();

  for (const file of files) {
    const contents = await fs.readFile(file, 'utf8');
    console.log(contents);
  }
}

Reading in parallel

If you want to read the files in parallel, you cannot use forEach indeed. Each of the async callback function calls does return a promise, but you're throwing them away instead of awaiting them. Just use map instead, and you can await the array of promises that you'll get with Promise.all:

async function printFiles () {
  const files = await getFilePaths();

  await Promise.all(files.map(async (file) => {
    const contents = await fs.readFile(file, 'utf8')
    console.log(contents)
  }));
}

For completeness and correct resource management:

        ICursor cursor = null;
        try
        {

            cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });

            if (cursor.Count > 0)
            {
                cursor.MoveToFirst();
            }
            return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
        }
        finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
        {
            if(cursor != null)
                cursor.Close();
        }

Simply put, in the first case, you are assigning multiple names to a list. Only one copy of list is created in memory and all names refer to that location. So changing the list using any of the names will actually modify the list in memory.

In the second case, multiple copies of same value are created in memory. So each copy is independent of one another.

Try to change Tomcat version, in my case tomcat "8.0.41" and "8.5.8" didn't work. But "8.5.37" worked fine.

This worked for me:

composer require "ext-gd:*" --ignore-platform-reqs

Normaly you can GET and POST parameters in a servlet the same way:

request.getParameter("cmd");

But only if the POST data is encoded as key-value pairs of content type: "application/x-www-form-urlencoded" like when you use a standard HTML form.

If you use a different encoding schema for your post data, as in your case when you post a json data stream, you need to use a custom decoder that can process the raw datastream from:

BufferedReader reader = request.getReader();

Json post processing example (uses org.json package )

public void doPost(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {

  StringBuffer jb = new StringBuffer();
  String line = null;
  try {
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null)
      jb.append(line);
  } catch (Exception e) { /*report an error*/ }

  try {
    JSONObject jsonObject =  HTTP.toJSONObject(jb.toString());
  } catch (JSONException e) {
    // crash and burn
    throw new IOException("Error parsing JSON request string");
  }

  // Work with the data using methods like...
  // int someInt = jsonObject.getInt("intParamName");
  // String someString = jsonObject.getString("stringParamName");
  // JSONObject nestedObj = jsonObject.getJSONObject("nestedObjName");
  // JSONArray arr = jsonObject.getJSONArray("arrayParamName");
  // etc...
}

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

Just change the color of layer of the header view

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
  UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0,    tableView.bounds.size.width, 30)] autorelease];
 headerView.layer.backgroundColor = [UIColor clearColor].CGColor
}

In SQL you need to use GETDATE():

UPDATE table SET date = GETDATE();

There is no NOW() function.

To answer your question:

In a large table, since the function is evaluated for each row, you will end up getting different values for the updated field.

So, if your requirement is to set it all to the same date I would do something like this (untested):

DECLARE @currDate DATETIME;
SET @currDate = GETDATE();

UPDATE table SET date = @currDate;

I had the same issue. Please follow these steps:

1. Make sure you have installed System.Data.SQLite.Core package by SQLite Development Team from NuGet.
2. Go to project solution and try to locate build folder inside packages folder
3. Check your project framework and pick the desired SQLite.Interop.dll and place it in your debug/release folder

Reference

Header fields are not copied to subsequent requests. You should use either cookie for this (addCookie method) or store "REMOTE_USER" in session (which you can obtain with getSession method).

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

You can potentially get a FileNotFoundException if the file does not exist.

Java documentation says:

Whether or not a file is available or may be created depends upon the underlying platform http://docs.oracle.com/javase/7/docs/api/java/io/FileOutputStream.html

If you're using Java 7 you can use the java.nio package:

The options parameter specifies how the the file is created or opened... it opens the file for writing, creating the file if it doesn't exist...

http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html

Looks like npm-check-updates is the only way to make this happen now.

npm i -g npm-check-updates
ncu -u
npm install

On npm <3.11:

Simply change every dependency's version to *, then run npm update --save. (Note: broken in recent (3.11) versions of npm).

Before:

  "dependencies": {
    "express": "*",
    "mongodb": "*",
    "underscore": "*",
    "rjs": "*",
    "jade": "*",
    "async": "*"
  }

After:

  "dependencies": {
    "express": "~3.2.0",
    "mongodb": "~1.2.14",
    "underscore": "~1.4.4",
    "rjs": "~2.10.0",
    "jade": "~0.29.0",
    "async": "~0.2.7"
  }

Of course, this is the blunt hammer of updating dependencies. It's fine if—as you said—the project is empty and nothing can break.

On the other hand, if you're working in a more mature project, you probably want to verify that there are no breaking changes in your dependencies before upgrading.

To see which modules are outdated, just run npm outdated. It will list any installed dependencies that have newer versions available.

You can use a variable to count places in the array, so when ever you add a new element, you put it in the right place. For example:

int a = 0;
int arr[5] = { };
arr[a] = 6;
a++;

If you ever happen to get this issue after running a git fetch and then git is not allowing you to run git pull because of a merge conflict (both modified / unmerged files, and to make you more frustrated, it won't show you any conflict markers in the file since it's not yet merged). If you do not wish to lose your work, you can do the following.

stage the file.

$ git add filename

then stash the local changes.

$ git stash

pull and update your working directory

$ git pull

restore your local modified file (git will automatically merge if it can, otherwise resolve it)

$ git stash pop

Hope it will help.

As @FelixKling pointed out, the most likely scenario is that the nodes you are looking for do not exist (yet).

However, modern development practices can often manipulate document elements outside of the document tree either with DocumentFragments or simply detaching/reattaching current elements directly. Such techniques may be used as part of JavaScript templating or to avoid excessive repaint/reflow operations while the elements in question are being heavily altered.

Similarly, the new "Shadow DOM" functionality being rolled out across modern browsers allows elements to be part of the document, but not query-able by document.getElementById and all of its sibling methods (querySelector, etc.). This is done to encapsulate functionality and specifically hide it.

Again, though, it is most likely that the element you are looking for simply is not (yet) in the document, and you should do as Felix suggests. However, you should also be aware that that is increasingly not the only reason that an element might be unfindable (either temporarily or permanently).

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

atan(x) Returns the principal value of the arc tangent of x, expressed in radians.

atan2(y,x) Returns the principal value of the arc tangent of y/x, expressed in radians.

Notice that because of the sign ambiguity, a function cannot determine with certainty in which quadrant the angle falls only by its tangent value (atan alone). You can use atan2 if you need to determine the quadrant.

You would have to use the JavascriptExecutor class:

WebDriver driver; // Assigned elsewhere
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('//id of element').setAttribute('attr', '10')");

You should have access to the POST dictionary on the request object.

I do it like this:

SELECT 1 FROM [dbo].[User] WHERE UserID = 20070022

Seeing as a boolean can never be null (at least in .NET), it should default to false or you can set it to that yourself if it's defaulting true. However 1 = true, so null = false, and no extra syntax.

Note: I use Dapper as my micro orm, I'd imagine ADO should work the same.

You most certainly have a databases tab in sql developer (all versions I've used in the past have this). Maybe check again? Perhaps, you're looking in the wrong location.

On a mac, the preferences is under "Oracle SQL Developer" (top left) -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

On windows (going from memory so might have to search if this isn't correct) Tools -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

Another approach is to use Collectors.toList:

targetLongList = 
    sourceLongList.stream().
    filter(l -> l > 100).
    collect(Collectors.toList());

Previous Solution:

Another approach is to use Collectors.toCollection:

targetLongList = 
    sourceLongList.stream().
    filter(l -> l > 100).
    collect(Collectors.toCollection(ArrayList::new));

The cause is that the remote peer closes its socket (crash for example), so if you try to write data to him for example, you will get this. to solve that, protect read/write to socket operations between (try catch), then manage the lose connection case into the catch (renew connection, stop program, ...etc):

 try {
      /* your code */
 } catch (SocketException e) {
      e.printStackTrace();
      /* insert your failure processings here */
 }

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

Example from the guide:

\newcommand{\example}[2][YYY]{Mandatory arg: #2;
                                 Optional arg: #1.}

This defines \example to be a command with two arguments, 
referred to as #1 and #2 in the {<definition>}--nothing new so far. 
But by adding a second optional argument to this \newcommand 
(the [YYY]) the first argument (#1) of the newly defined 
command \example is made optional with its default value being YYY.

Thus the usage of \example is either:

   \example{BBB}
which prints:
Mandatory arg: BBB; Optional arg: YYY.
or:
   \example[XXX]{AAA}
which prints:
Mandatory arg: AAA; Optional arg: XXX.

Haven't tested this fully but since iOS fires touch events, this could work, assuming you are in a jQuery setting.

$('a').on('click touchend', function(e) {
    var el = $(this);
    var link = el.attr('href');
    window.location = link;
});

The idea is that Mobile WebKit fires a touchend event at the end of a tap so we listen for that and then redirect the browser as soon as a touchend event has been fired on a link.

strtolower is lacking in several of the proposed solutions, RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. The whole thing, not just the value part.

So suggestions like only parsing HTTP_ entries are wrong.

Better would be like this:

if (!function_exists('getallheaders')) {
    foreach ($_SERVER as $name => $value) {
        /* RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. */
        if (strtolower(substr($name, 0, 5)) == 'http_') {
            $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
        }
    }
    $this->request_headers = $headers;
} else {
    $this->request_headers = getallheaders();
}

Notice the subtle differences with previous suggestions. The function here also works on php-fpm (+nginx).

It is not possible to add comments to 'normal' Access queries, that is, a QueryDef in an mdb, which is why a number of people recommend storing the sql for queries in a table.

If 'they' are using a self-signed certificate it is up to them to take the steps required to make their server usable. Specifically that means providing their certificate to you offline in a trustworthy way. So get them to do that. You then import that into your truststore using the keytool as described in the JSSE Reference Guide. Don't even think about the insecure TrustManager posted here.

EDIT For the benefit of the seventeen (!) downvoters, and numerous commenters below, who clearly have not actually read what I have written here, this is not a jeremiad against self-signed certificates. There is nothing wrong with self-signed certificates when implemented correctly. But, the correct way to implement them is to have the certificate delivered securely via an offline process, rather than via the unauthenticated channel they are going to be used to authenticate. Surely this is obvious? It is certainly obvious to every security-aware organization I have ever worked for, from banks with thousands of branches to my own companies. The client-side code-base 'solution' of trusting all certificates, including self-signed certificates signed by absolutely anybody, or any arbitary body setting itself up as a CA, is ipso facto not secure. It is just playing at security. It is pointless. You are having a private, tamperproof, reply-proof, injection-proof conversation with ... somebody. Anybody. A man in the middle. An impersonator. Anybody. You may as well just use plaintext.

I wanted to do the same, and I had first problems with the split function, then problems with installing pandas 0.15.2, so I went back to my old version, and wrote a little function that works very well. I hope this can help!

# input - df: a Dataframe, chunkSize: the chunk size
# output - a list of DataFrame
# purpose - splits the DataFrame into smaller chunks
def split_dataframe(df, chunk_size = 10000): 
    chunks = list()
    num_chunks = len(df) // chunk_size + 1
    for i in range(num_chunks):
        chunks.append(df[i*chunk_size:(i+1)*chunk_size])
    return chunks

I've found that it's best not to mess around with setting the measured dimensions yourself. There's actually a bit of negotiation that goes on between the parent and child views and you don't want to re-write all that code.

What you can do, though, is modify the measureSpecs, then call super with them. Your view will never know that it's getting a modified message from its parent and will take care of everything for you:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
    int myWidth = (int) (parentHeight * 0.5);
    super.onMeasure(MeasureSpec.makeMeasureSpec(myWidth, MeasureSpec.EXACTLY), heightMeasureSpec);
}

In Java, console input is accomplished by reading from System.in. To obtain a character based stream that is attached to the console, wrap System.in in a BufferedReader object. BufferedReader supports a buffered input stream. Its most commonly used constructor is shown here:

BufferedReader(Reader inputReader)

Here, inputReader is the stream that is linked to the instance of BufferedReader that is being created. Reader is an abstract class. One of its concrete subclasses is InputStreamReader, which converts bytes to characters.

To obtain an InputStreamReader object that is linked to System.in, use the following constructor:

InputStreamReader(InputStream inputStream)

Because System.in refers to an object of type InputStream, it can be used for inputStream. Putting it all together, the following line of code creates a BufferedReader that is connected to the keyboard:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

After this statement executes, br is a character-based stream that is linked to the console through System.in.

This is taken from the book Java- The Complete Reference by Herbert Schildt

You can't.. You would have to know:

• How far is the object (you can know your location from GPS.. but the object's location?)
• What is the focal length of the camera

Maybe, just maybe if the object was optically tagged with for example a QR code, and you have a code-to-loc map...

The "manual bootstrap" case can gain access to Angular services by manually creating an injector before bootstrap. This initial injector will stand alone (not be attached to any elements) and include only a subset of the modules that are loaded. If all you need is core Angular services, it's sufficient to just load ng, like this:

angular.element(document).ready(
    function() {
        var initInjector = angular.injector(['ng']);
        var $http = initInjector.get('$http');
        $http.get('/config.json').then(
            function (response) {
               var config = response.data;
               // Add additional services/constants/variables to your app,
               // and then finally bootstrap it:
               angular.bootstrap(document, ['myApp']);
            }
        );
    }
);

You can, for example, use the module.constant mechanism to make data available to your app:

myApp.constant('myAppConfig', data);

This myAppConfig can now be injected just like any other service, and in particular it's available during the configuration phase:

myApp.config(
    function (myAppConfig, someService) {
        someService.config(myAppConfig.someServiceConfig);
    }
);

or, for a smaller app, you could just inject the global config directly into your service, at the expense of spreading knowledge about the configuration format throughout the application.

Of course, since the async operations here will block the bootstrap of the application, and thus block the compilation/linking of the template, it's wise to use the ng-cloak directive to prevent the unparsed template from showing up during the work. You could also provide some sort of loading indication in the DOM , by providing some HTML that gets shown only until AngularJS initializes:

<div ng-if="initialLoad">
    <!-- initialLoad never gets set, so this div vanishes as soon as Angular is done compiling -->
    <p>Loading the app.....</p>
</div>
<div ng-cloak>
    <!-- ng-cloak attribute is removed once the app is done bootstrapping -->
    <p>Done loading the app!</p>
</div>

I created a complete, working example of this approach on Plunker, loading the configuration from a static JSON file as an example.

To only way in Java 6 or earlier is with a so called StreamGobbler (which you are started to create):

StreamGobbler errorGobbler = new StreamGobbler(p.getErrorStream(), "ERROR");

// any output?
StreamGobbler outputGobbler = new StreamGobbler(p.getInputStream(), "OUTPUT");

// start gobblers
outputGobbler.start();
errorGobbler.start();

...

private class StreamGobbler extends Thread {
    InputStream is;
    String type;

    private StreamGobbler(InputStream is, String type) {
        this.is = is;
        this.type = type;
    }

    @Override
    public void run() {
        try {
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            while ((line = br.readLine()) != null)
                System.out.println(type + "> " + line);
        }
        catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }
}

For Java 7, see Evgeniy Dorofeev's answer.

Use the $_SERVER['HTTP_REFERER'] header, but bear in mind anybody can spoof it at anytime regardless of whether they clicked on a link.

I've had multenum for "Multi-column enumerated lists" recommended to me, but I've never actually used it myself, yet.

Edit: The syntax doesn't exactly look like you could easily copy+paste lists into the LaTeX code. So, it may not be the best solution for your use case!

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

memset is generally designed to be very very fast general-purpose setting/zeroing code. It handles all cases with different sizes and alignments, which affect the kinds of instructions you can use to do your work. Depending on what system you're on (and what vendor your stdlib comes from), the underlying implementation might be in assembler specific to that architecture to take advantage of whatever its native properties are. It might also have internal special cases to handle the case of zeroing (versus setting some other value).

That said, if you have very specific, very performance critical memory zeroing to do, it's certainly possible that you could beat a specific memset implementation by doing it yourself. memset and its friends in the standard library are always fun targets for one-upmanship programming. :)

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Method 1:

   DataView view = new DataView(table);
   DataTable distinctValues = view.ToTable(true, "id");

Method 2: You will have to create a class matching your datatable column names and then you can use the following extension method to convert Datatable to List

    public static List<T> ToList<T>(this DataTable table) where T : new()
    {
        List<PropertyInfo> properties = typeof(T).GetProperties().ToList();
        List<T> result = new List<T>();

        foreach (var row in table.Rows)
        {
            var item = CreateItemFromRow<T>((DataRow)row, properties);
            result.Add(item);
        }

        return result;
    }

    private static T CreateItemFromRow<T>(DataRow row, List<PropertyInfo> properties) where T : new()
    {
        T item = new T();
        foreach (var property in properties)
        {
            if (row.Table.Columns.Contains(property.Name))
            {
                if (row[property.Name] != DBNull.Value)
                    property.SetValue(item, row[property.Name], null);
            }
        }
        return item;
    }

and then you can get distinct from list using

      YourList.Select(x => x.Id).Distinct();

Please note that this will return you complete Records and not just ids.

Environmental Variables

When compiling your Wxs documents to wixobj code, you can make use of environmental variables to determine various information. For example, lets say you want to change which files get included in a project. Lets say you have an environmental variable called RELEASE_MODE, that you set right before you build your MSI (either with a script or manually, it doesn't matter) In your wix source, you can do something like:

<define FILESOURCE = c:\source\output\bin\$(env.RELEASE_MODE) >

and then later in your code, use it in place to on the fly change your wxs document, eg:

<Icon Id="myicon.ico" SourceFile="$(var.FILESOURCE)" />

Here is a workaround to copy all the objects from one arrayList to another:

 ArrayList<Object> myObject = new ArrayList<Object>();
ArrayList<Object> myTempObject = new ArrayList<Object>();

myObject.addAll(myTempObject.subList(0, myTempObject.size()));

subList is intended to return a List with a range of data. so you can copy the whole arrayList or part of it.

%DATE% is not your friend. Because the %DATE% environment variable (and the DATE command) returns the current date using the Windows short date format that is fully and endlessly customizable. One user may configure the system to return 07/06/2012 while another might choose Fri060712. Using %DATE% is a complete nightmare for a BAT programmer.

There are two possible approaches to solve this problem:

1. You may be tempted to temporarily change the short date format, by changing the locale settings in the registry value HKCU\Control Panel\International\sShortDate, to your recognizable format. Then access %DATE% to get the date in the format you want; and finally restore the format back to the original user format. Something like this

   reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f >nul
   reg add "HKCU\Control Panel\International" /v sShortDate /d "ddd" /f >nul
   set DOW=%DATE%
   reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f >nul
   

   but this method has two problems:

   • it tampers with a global registry value for its local particular purpouses, so it may interfere with other processes or user tasks that at the very same time query the date in short date format, including itself if run simultaneously.

   • and it returns the three letter day of the week in the local language that may be different in different systems or different users.

2. use WMIC Win32_LocalTime, that returns the date in a convenient way to directly parse it with a FOR command.

   FOR /F "skip=1" %%A IN ('WMIC Path Win32_LocalTime Get DayOfWeek' ) DO (
     set DOW=%%A
   )
   

   this is the method I recommend.

when it gets out from the using statement the Dispose method will be called automatically closing the stream

try the below:

using (var ms = new MemoryStream())
{
    var sw = new StreamWriter(ms);

        sw.WriteLine("data");
        sw.WriteLine("data 2");
        ms.Position = 0;
        using (var sr = new StreamReader(ms))
        {
            Console.WriteLine(sr.ReadToEnd());
        }
}    

Only the answers that push the value into the registry affect a permanent change (so the majority of answers on this thread, including the accepted answer, do not permanently affect the Path).

The following function works for both Path / PSModulePath and for User / System types. It will also add the new path to the current session by default.

function AddTo-Path {
    param ( 
        [string]$PathToAdd,
        [Parameter(Mandatory=$true)][ValidateSet('System','User')][string]$UserType,
        [Parameter(Mandatory=$true)][ValidateSet('Path','PSModulePath')][string]$PathType
    )

    # AddTo-Path "C:\XXX" "PSModulePath" 'System' 
    if ($UserType -eq "System" ) { $RegPropertyLocation = 'HKLM:\System\CurrentControlSet\Control\Session Manager\Environment' }
    if ($UserType -eq "User"   ) { $RegPropertyLocation = 'HKCU:\Environment' } # also note: Registry::HKEY_LOCAL_MACHINE\ format
    $PathOld = (Get-ItemProperty -Path $RegPropertyLocation -Name $PathType).$PathType
    "`n$UserType $PathType Before:`n$PathOld`n"
    $PathArray = $PathOld -Split ";" -replace "\\+$", ""
    if ($PathArray -notcontains $PathToAdd) {
        "$UserType $PathType Now:"   # ; sleep -Milliseconds 100   # Might need pause to prevent text being after Path output(!)
        $PathNew = "$PathOld;$PathToAdd"
        Set-ItemProperty -Path $RegPropertyLocation -Name $PathType -Value $PathNew
        Get-ItemProperty -Path $RegPropertyLocation -Name $PathType | select -ExpandProperty $PathType
        if ($PathType -eq "Path") { $env:Path += ";$PathToAdd" }                  # Add to Path also for this current session
        if ($PathType -eq "PSModulePath") { $env:PSModulePath += ";$PathToAdd" }  # Add to PSModulePath also for this current session
        "`n$PathToAdd has been added to the $UserType $PathType"
    }
    else {
        "'$PathToAdd' is already in the $UserType $PathType. Nothing to do."
    }
}

# Add "C:\XXX" to User Path (but only if not already present)
AddTo-Path "C:\XXX" "User" "Path"

# Just show the current status by putting an empty path
AddTo-Path "" "User" "Path"

An example would be nice - here's a trivial one

for %I in (*.*) do @echo %~xI

it lists only the EXTENSIONS of each file in current folder

for more useful variable combinations (also listed in previous response) from the CMD prompt execute: HELP FOR which contains this snippet

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line

If you want to extract a raw-ish value from a HSSF cell, you can use something like this code fragment:

CellBase base = (CellBase) cell;
CellType cellType = cell.getCellType();
base.setCellType(CellType.STRING);
String result = cell.getStringCellValue();
base.setCellType(cellType);

At least for strings that are completely composed of digits (and automatically converted to numbers by Excel), this returns the original string (e.g. "12345") instead of a fractional value (e.g. "12345.0"). Note that setCellType is available in interface Cell(as of v. 4.1) but deprecated and announced to be eliminated in v 5.x, whereas this method is still available in class CellBase. Obviously, it would be nicer either to have getRawValue in the Cell interface or at least to be able use getStringCellValue on non STRING cell types. Unfortunately, all replacements of setCellType mentioned in the description won't cover this use case (maybe a member of the POI dev team reads this answer).

make sure that you insert your module and controller in your index.html first. then use this code in your module var app = angular.module("MesaViewer", []);

Is this what you're looking for?

When you have multiple if conditions, numpy.select is the way to go:

In [4096]: choices = [0, 1, -1]

In [4100]: df['C'] = np.select(conditions, choices)

In [4101]: df

Found an awesome JavaScript version here: http://oskarhane.com/create-a-nested-array-recursively-in-javascript/

Let’s say you have an array like this:

const models = [
    {id: 1, title: 'hello', parent: 0},
    {id: 2, title: 'hello', parent: 0},
    {id: 3, title: 'hello', parent: 1},
    {id: 4, title: 'hello', parent: 3},
    {id: 5, title: 'hello', parent: 4},
    {id: 6, title: 'hello', parent: 4},
    {id: 7, title: 'hello', parent: 3},
    {id: 8, title: 'hello', parent: 2}
];

And you want to have the objects nested like this:

const nestedStructure = [
    {
        id: 1, title: 'hello', parent: 0, children: [
            {
                id: 3, title: 'hello', parent: 1, children: [
                    {
                        id: 4, title: 'hello', parent: 3, children: [
                            {id: 5, title: 'hello', parent: 4},
                            {id: 6, title: 'hello', parent: 4}
                        ]
                    },
                    {id: 7, title: 'hello', parent: 3}
                ]
            }
        ]
    },
    {
        id: 2, title: 'hello', parent: 0, children: [
            {id: 8, title: 'hello', parent: 2}
        ]
    }
];

Here’s a recursive function that makes it happen.

function getNestedChildren(models, parentId) {
    const nestedTreeStructure = [];
    const length = models.length;

    for (let i = 0; i < length; i++) { // for-loop for perf reasons, huge difference in ie11
        const model = models[i];

        if (model.parent == parentId) {
            const children = getNestedChildren(models, model.id);

            if (children.length > 0) {
                model.children = children;
            }

            nestedTreeStructure.push(model);
        }
    }

    return nestedTreeStructure;
}

Usuage:

const models = [
    {id: 1, title: 'hello', parent: 0},
    {id: 2, title: 'hello', parent: 0},
    {id: 3, title: 'hello', parent: 1},
    {id: 4, title: 'hello', parent: 3},
    {id: 5, title: 'hello', parent: 4},
    {id: 6, title: 'hello', parent: 4},
    {id: 7, title: 'hello', parent: 3},
    {id: 8, title: 'hello', parent: 2}
];
const nestedStructure = getNestedChildren(models, 0);

black magic:

<style>
body { float:left;}
.success { background-color: #ccffcc;}
</style>

If anyone has a clear explanation of why this works, please comment. I think it has something to do with a side effect of the float that removes the constraint that the body must fit into the page width.

If the .project and .classpath are already committed, then they need to be removed from the index (but not the disk)

git rm --cached .project
git rm --cached .classpath

Then the .gitignore would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse file will then work, which does include:

# Eclipse Core      
.project

# JDT-specific (Eclipse Java Development Tools)     
.classpath

Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR set to a shared folder accessible by all).
That template folder can contain an info/exclude file, with ignore rules that you want enforced for all repos, including the new ones (git init) that any user would use.

When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files .classpath and .project from the repo.

find . -name "*.mp3" -exec mv --target-directory=/home/d0k/??????/ {} \+

You must use %ld to print a long int, and %lld to print a long long int.

Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you're using).

You will also need to ensure that you use your compiler in a C99-compatible mode (for example, using the -std=gnu99 option to gcc). This is because the long long int type was not introduced until C99; and although many compilers implement long long int in C90 mode as an extension, the constant 2147483648 may have a type of unsigned int or unsigned long in C90. If this is the case in your implementation, then the value of -2147483648 will also have unsigned type and will therefore be positive, and the overall result will be not what you expect.

I did a work around. I had a hidden textbox to hold the value. Then, on form_onsubmit, I copied the path value, less the file name to the hidden folder. Then, set the fileInput box to "". That way, no file is uploaded. I don't recall the event of the fileUpload control. Maybe onchange. It's been a while. If there's a value, I parse off the file name and put the folder back to the box. Of, course you'd validate that the file as a valid file. This would give you the clients workstation folder.
However, if you want to reflect server paths, that requires a whole different coding approach.

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

To begin with (and unrelated), instantiating the Application class by yourself does not seem to be its intended use. From what one can read from its source, you are rather expected to use the static instance returned by getApplication().

Now let's get to the error Eclipse reports. I've ran into a similar issue recently: Access restriction: The method ... is not API (restriction on required project). I called the method in question as a method of an object which inherited that method from a super class. All I had to do was to add the package the super class was in to the packages imported by my plugin.

However, there is a lot of different causes for errors based on "restriction on required project/library". Similar to the problem described above, the type you are using might have dependencies to packages that are not exported by the library or might not be exported itself. In that case you can try to track down the missing packages and export them my yourself, as suggested here, or try Access Rules. Other possible scenarios include:

• Eclipse wants to keep you from using available packages that are not part of the public Java API (solution 1, 2)
• Dependencies are satisfied by multiple sources, versions are conflicting etc. (solution 1, 2, 3)
• Eclipse is using a JRE where a JDK is necessary (which might be the case here, from what your errors say; solution) or JRE/JDK version in project build path is not the right one

This ended up as more like a medley of restriction-related issues than an actual answer. But since restriction on required projects is such a versatile error to be reported, the perfect recipe is probably still to be found.

I got this error after uninstalling Windows Server Update Services (WSUS) from the computer running IIS. Apparently uninstalling WSUS may break the IIS configuration on the server making other web application installed on the same server unavailable.

I found the solution for the problem here.

You should place below line

btn.Click = btn.Click + btn1_Click;

Obviously @Lasse solution is right, but there's another way to solve your problem: T-SQL operator LIKE defines the optional ESCAPE clause, that lets you declare a character which will escape the next character into the pattern.

For your case, the following WHERE clauses are equivalent:

WHERE username LIKE '%[_]d';            -- @Lasse solution
WHERE username LIKE '%$_d' ESCAPE '$';
WHERE username LIKE '%^_d' ESCAPE '^';

imageToBase64 = (URL) => {
    let image;

    image.crossOrigin = 'Anonymous';

        let context = canvas.getContext('2d');
        canvas.width = image.width;
        canvas.height = image.height;
        context.drawImage(image, 0, 0);

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

[Edit] There's another solution not mentioned yet, and it seems to outperform the others given so far in most cases.

Use string.translate to replace all valid characters in the string, and see if we have any invalid ones left over. This is pretty fast as it uses the underlying C function to do the work, with very little python bytecode involved.

Obviously performance isn't everything - going for the most readable solutions is probably the best approach when not in a performance critical codepath, but just to see how the solutions stack up, here's a performance comparison of all the methods proposed so far. check_trans is the one using the string.translate method.

Test code:

import string, re, timeit

pat = re.compile('[\w-]*$')
pat_inv = re.compile ('[^\w-]')
allowed_chars=string.ascii_letters + string.digits + '_-'
allowed_set = set(allowed_chars)
trans_table = string.maketrans('','')

def check_set_diff(s):
    return not set(s) - allowed_set

def check_set_all(s):
    return all(x in allowed_set for x in s)

def check_set_subset(s):
    return set(s).issubset(allowed_set)

def check_re_match(s):
    return pat.match(s)

def check_re_inverse(s): # Search for non-matching character.
    return not pat_inv.search(s)

def check_trans(s):
    return not s.translate(trans_table,allowed_chars)

test_long_valid='a_very_long_string_that_is_completely_valid_' * 99
test_short_valid='short_valid_string'
test_short_invalid='/$%$%&'
test_long_invalid='/$%$%&' * 99
test_empty=''

def main():
    funcs = sorted(f for f in globals() if f.startswith('check_'))
    tests = sorted(f for f in globals() if f.startswith('test_'))
    for test in tests:
        print "Test %-15s (length = %d):" % (test, len(globals()[test]))
        for func in funcs:
            print "  %-20s : %.3f" % (func, 
                   timeit.Timer('%s(%s)' % (func, test), 'from __main__ import pat,allowed_set,%s' % ','.join(funcs+tests)).timeit(10000))
        print

The translate approach seems best in most cases, dramatically so with long valid strings, but is beaten out by regexes in test_long_invalid (Presumably because the regex can bail out immediately, but translate always has to scan the whole string). The set approaches are usually worst, beating regexes only for the empty string case.

Using all(x in allowed_set for x in s) performs well if it bails out early, but can be bad if it has to iterate through every character. isSubSet and set difference are comparable, and are consistently proportional to the length of the string regardless of the data.

There's a similar difference between the regex methods matching all valid characters and searching for invalid characters. Matching performs a little better when checking for a long, but fully valid string, but worse for invalid characters near the end of the string.

I am not certain about what precisely you are trying to do, but I think this SQL function will help you:

SELECT DATEADD(day,-1,'2013-04-01 16:25:00.250')

The above will give you 2013-03-31 16:25:00.250.

It takes you back exactly one day and works on any standard date-time or date format.

Try running this command and see if it gives you what you are looking for:

SELECT DATEADD(day,-1,@CreatedDate)

1) You can create rounded corner button by defining xml drawable and you can increase or decrease radius to increase or decrease roundness of button corner. Set this xml drawable as background of button.

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="4dp"
    android:insetTop="6dp"
    android:insetRight="4dp"
    android:insetBottom="6dp">
    <ripple android:color="?attr/colorControlHighlight">
        <item>
            <shape android:shape="rectangle"
                android:tint="#0091ea">
                <corners android:radius="10dp" />
                <solid android:color="#1a237e" />
                <padding android:bottom="6dp" />
            </shape>

2) To change default shadow and shadow transition animation between button states, you need to define selector and apply it to button using android:stateListAnimator property. For complete button customization reference : http://www.zoftino.com/android-button

While admittedly a bit obscure, I would say that the most typographically pleasing way of doing this is

Just to demonstrate the changes that editor.renderWhitespace : none||boundary||all will do to your VSCode I added this screenshot:

Where Tab are ? and Spaceare .

Just do a random click on any non input item. Keyboard will disappear.

"SELECT *
  INTO 
    @TempCustomer 
FROM 
    Customer
WHERE 
    CustomerId = @CustomerId"

Which means creating a new @tempCustomer tablevariable and inserting data FROM Customer. You had already declared it above so no need of again declaring. Better to go with

INSERT INTO @tempCustomer SELECT * FROM Customer

FWIW, this config worked for me:

location = /logpush.html {
  if ($request_method = POST) {
    access_log /var/log/nginx/push.log push_requests;
    proxy_pass $scheme://127.0.0.1/logsink;
    break;
  }   
  return 200 $scheme://$host/serviceup.html;
}   
#
location /logsink {
  return 200;
}

The standard way to do this sort of thing is to use external tools. Disallowing the use of external tools while writing a shell script is absurd. However, if you really don't want to use external tools, you can print line 5 with:

i=0; while read line; do test $((++i)) = 5 && echo "$line"; done < input-file

Note that this will print logical line 5. That is, if input-file contains line continuations, they will be counted as a single line. You can change this behavior by adding -r to the read command. (Which is probably the desired behavior.)

How did you configure networking when you created the guest? The easiest way is to set the network adapter to NAT, if you don't need to access the vm from another pc.

Quite simply, both lines create the object on the stack, rather than on the heap as 'new' does. The second line actually involves a second call to a copy constructor, so it should be avoided (it also needs to be corrected as indicated in the comments). You should use the stack for small objects as much as possible since it is faster, however if your objects are going to survive for longer than the stack frame, then it's clearly the wrong choice.

We should set to overflow: auto and hide a scrollbar which we don't use for working on unsupporting CSS3 browser. Look at this CSS Overflow; XME.im

There's still no simple answer. It depends on your scenario. MSDN has documentation to help you decide.

There are other options covered here. Instead of storing in the file system directly or in a BLOB, you can use the FileStream or File Table in SQL Server 2012. The advantages to File Table seem like a no-brainier (but admittedly I have no personal first-hand experience with them.)

The article is definitely worth a read.

Just something I found for Wordpress users,

As obvious as it sounds, If your div is returning some AJAX content based on say a header that would commonly link out to a new post page, some tutorials will say to return false since you're returning the post data on the same page and the return would prevent the page from moving. However if you return false, you also prevent Fancybox2 from doing it's thing as well. I spent hours trying to figure that stupid simple thing out.

So for these kind of links, just make sure that the href property is the hashed (#) div you wish to select, and in your javascript, make sure that you do not return false since you no longer will need to.

Simple I know ^_^

math.fabs() converts its argument to float if it can (if it can't, it throws an exception). It then takes the absolute value, and returns the result as a float.

In addition to floats, abs() also works with integers and complex numbers. Its return type depends on the type of its argument.

In [7]: type(abs(-2))
Out[7]: int

In [8]: type(abs(-2.0))
Out[8]: float

In [9]: type(abs(3+4j))
Out[9]: float

In [10]: type(math.fabs(-2))

In [11]: type(math.fabs(-2.0))
Out[11]: float

Update February 2016:

www.javadecompilers.com lists JAD as being:

the most popular Java decompiler, but primarily of this age only. Written in C++, so very fast.
Outdated, unsupported and does not decompile correctly Java 5 and later

So your mileage may vary with recent jdk (7, 8).

The same site list other tools.

And javadecompiler, as noted by Salvador Valencia in the comments (Sept 2017), offers a SaaS where you upload the .class file to the cloud and it returns you the decompiled code.

Original answer: Oct. 2008

• The final release of JSR 176, defining the major features of J2SE 5.0 (Java SE 5), has been published on September 30, 2004.
• The lastest Java version supported by JAD, the famous Java decompiler written by Mr. Pavel Kouznetsov, is JDK 1.3.
• Most of the Java decompilers downloadable today from the Internet, such as “DJ Java Decompiler” or “Cavaj Java Decompiler”, are powered by JAD: they can not display Java 5 sources.

Java Decompiler (Yet another Fast Java decompiler) has:

• Explicit support for decompiling and analyzing Java 5+ “.class” files.
• A nice GUI:

It works with compilers from JDK 1.1.8 up to JDK 1.7.0, and others (Jikes, JRockit, etc.).

It features an online live demo version that is actually fully functional! You can just drop a jar file on the page and see the decompiled source code without installing anything.

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

Use this plugin

Fluttertoast.showToast(
        msg: "This is Toast messaget",
        toastLength: Toast.LENGTH_SHORT,
        gravity: ToastGravity.CENTER,
        timeInSecForIos: 1
    );

You can get column type of DataTable with DataType attribute of datatable column like below:

var type = dt.Columns[0].DataType

dt : DataTable object.

0 : DataTable column index.

Hope It Helps

You could use lsof to see what application is listening on port 80:

sudo lsof -i TCP:80

Try clearing your browsers cache.

It's a one-liner with mutate_at:

dat %>% mutate_at("l1", factor) %>% mutate_at("l2", as.numeric)

You could use a @HostListener decorator. Works with Angular 4 and up.

import { HostListener } from '@angular/core';

@HostListener("window:scroll", []) onWindowScroll() {
    // do some stuff here when the window is scrolled
    const verticalOffset = window.pageYOffset 
          || document.documentElement.scrollTop 
          || document.body.scrollTop || 0;
}

Base on Francisco Daniel's answer I modified some of the Jquery code here's My version. I removed some excess code and use "fa" instead of "far" for the icon. I also remove the "far fa-minus-square" since I can't understand its purpose.

-- Edited --

I added the "draw" event for the button icon to update whenever the table is redrawn or reloaded. Because I noticed when I tried to reload the table using "myTable.ajax.reload()" the button icon is not changing.

You can't use {{}} when using angular directives for binding with ng-model but for binding non-angular attributes you would have to use {{}}..

Eg:

ng-show="my-model"
title = "{{my-model}}"

Try this:

import re

mystr = 'This is a string, with words!'
wordList = re.sub("[^\w]", " ",  mystr).split()

How it works:

From the docs :

re.sub(pattern, repl, string, count=0, flags=0)

Return the string obtained by replacing the leftmost non-overlapping occurrences of pattern in string by the replacement repl. If the pattern isn’t found, string is returned unchanged. repl can be a string or a function.

so in our case :

pattern is any non-alphanumeric character.

[\w] means any alphanumeric character and is equal to the character set [a-zA-Z0-9_]

a to z, A to Z , 0 to 9 and underscore.

so we match any non-alphanumeric character and replace it with a space .

and then we split() it which splits string by space and converts it to a list

so 'hello-world'

becomes 'hello world'

with re.sub

and then ['hello' , 'world']

after split()

let me know if any doubts come up.

In my case, the setting was HKEY_CURRENT_USER\Software\Policies\Google\Chrome

I deleted Chrome and everything is fine now.

If your start and end datetimes are on different days use TIMEDIFF.

SELECT TIMEDIFF(datetime1,datetime2)

if datetime1 > datetime2 then

SELECT TIMEDIFF("2019-02-20 23:46:00","2019-02-19 23:45:00")

gives: 24:01:00

and datetime1 < datetime2

SELECT TIMEDIFF("2019-02-19 23:45:00","2019-02-20 23:46:00")

gives: -24:01:00

You need to make sure if package.json file exist in app folder. i run into same problem differently but solution would be same

Run this command where "package.json" file exist. even i experience similar problem then i change the folder and got resolve it. for more explanation i run c:\selfPractice> npm start whereas my package.json resides in c:\selfPractice\frontend> then i change the folder and run c:\selfPractice\frontend> npm start and it got run

Not the same, but idea that works anyway.

#!/bin/bash  
i='y'  
while [ ${i:0:1} != n ]  
do  
    # Command(s)  
    read -p " Again? Y/n " i  
    [[ ${#i} -eq 0 ]] && i='y'  
done  

Output:
Again? Y/n N
Again? Y/n Anything
Again? Y/n 7
Again? Y/n &
Again? Y/n nsijf
$

Now only checks 1st character of $i read.

You need to pass the variable into the function:

$data = 'My data';

function menugen($data)
{
    echo $data;
}

To disagree with the official answer:

:set list will not show ^M characters (CRs). Supplying the -b option to vi/vim will work. Or, once vim is loaded, type :e ++ff=unix.

Operator? NO, but I think you can change your culture so that string comparison is not case-sensitive.

// you'll want to change this...
System.Threading.Thread.CurrentThread.CurrentCulture
// and you'll want to custimize this
System.Globalization.CultureInfo.CompareInfo

I'm confident that it will change the way that strings are being compared by the equals operator.

Parsing dates is a pain in JavaScript as there's no extensive native support. However you could do something like the following by relying on the Date(year, month, day [, hour, minute, second, millisecond]) constructor signature of the Date object.

var dateString = '17-09-2013 10:08',
    dateTimeParts = dateString.split(' '),
    timeParts = dateTimeParts[1].split(':'),
    dateParts = dateTimeParts[0].split('-'),
    date;

date = new Date(dateParts[2], parseInt(dateParts[1], 10) - 1, dateParts[0], timeParts[0], timeParts[1]);

console.log(date.getTime()); //1379426880000
console.log(date); //Tue Sep 17 2013 10:08:00 GMT-0400

You could also use a regular expression with capturing groups to parse the date string in one line.

var dateParts = '17-09-2013 10:08'.match(/(\d+)-(\d+)-(\d+) (\d+):(\d+)/);

console.log(dateParts); // ["17-09-2013 10:08", "17", "09", "2013", "10", "08"]

Using npm

Latest version while still respecting the semver in your package.json: npm update <package-name>. So, if your package.json says "react": "^15.0.0" and you run npm update react your package.json will now say "react": "^15.6.2" (the currently latest version of react 15).

But since you want to go from react 15 to react 16, that won't do. Latest version regardless of your semver: npm install --save react@latest.

If you want a specific version, you run npm install --save react@<version> e.g. npm install --save [email protected].

https://docs.npmjs.com/cli/install

Using yarn

Latest version while still respecting the semver in your package.json: yarn upgrade react.

Latest version regardless of your semver: yarn upgrade react@latest.

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

You are looking for the break statement.

$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
while (list(, $val) = each($arr)) {
    if ($val == 'stop') {
        break;    /* You could also write 'break 1;' here. */
    }
    echo "$val<br />\n";
}

Copy this method into your class

 public int getArrayIndex(int[] arr,int value) {

        int k=0;
        for(int i=0;i<arr.length;i++){

            if(arr[i]==value){
                k=i;
                break;
            }
        }
    return k;
}

Call this method with pass two perameters Array and value and store its return value in a integer variable.

int indexNum = getArrayIndex(array,value);

Thank you

The 4K limit you read about is for the entire cookie, including name, value, expiry date etc. If you want to support most browsers, I suggest keeping the name under 4000 bytes, and the overall cookie size under 4093 bytes.

One thing to be careful of: if the name is too big you cannot delete the cookie (at least in JavaScript). A cookie is deleted by updating it and setting it to expire. If the name is too big, say 4090 bytes, I found that I could not set an expiry date. I only looked into this out of interest, not that I plan to have a name that big.

To read more about it, here are the "Browser Cookie Limits" for common browsers.

While on the subject, if you want to support most browsers, then do not exceed 50 cookies per domain, and 4093 bytes per domain. That is, the size of all cookies should not exceed 4093 bytes.

This means you can have 1 cookie of 4093 bytes, or 2 cookies of 2045 bytes, etc.

I used to say 4095 bytes due to IE7, however now Mobile Safari comes in with 4096 bytes with a 3 byte overhead per cookie, so 4093 bytes max.

for i in range(1,len(na_rm.columns)):
           print ("column name:", na_rm.columns[i])

Output :

column name: seretide_price
column name: symbicort_mkt_shr
column name: symbicort_price

Those using a buffer or tree navigation plugin, like Buffergator or NERDTree, will need to toggle these splits before destroying the current buffer - else you'll send your splits into wonkyville

Where "NERDTreeToggle" in that list is the same as typing :NERDTreeToggle. You can modify this function to integrate with your own configuration.

Try using something like

File.Create

Creates or overwrites a file in the specified path.

Procedural generation only means that code is used to generate the data instead of it being hand made. For example if you want to generate a forest with various trees you are not going to design each tree by hand, thus coding is more efficient to generate the variations. It could be the generation of the tree graphics, size, structure, placement ...

In general there is some kind of interation with a few rules, in addition to that you can add some randomness and logic of your own, combine all of these techniques ... Anything somewhat chaotic but not too chaotic can yield interesting results.

Here are a few notable techniques:

• https://en.wikipedia.org/wiki/Cellular_automaton
• https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life (notable cellular automaton)
• Book: https://en.wikipedia.org/wiki/A_New_Kind_of_Science
• Fractals: https://en.wikipedia.org/wiki/Fractal
• Plants: https://en.wikipedia.org/wiki/L-system
• Terrain or maps, textures, smoke, clouds, turbulence: https://en.wikipedia.org/wiki/Perlin_noise
• Terrain or maps: https://en.wikipedia.org/wiki/Voronoi_diagram

A few games famous for their procedural generation:

• https://en.wikipedia.org/wiki/Rogue_(video_game) and roguelikes in general
• https://en.wikipedia.org/wiki/Elite_(video_game) random seed ...
• https://en.wikipedia.org/wiki/.kkrieger The entire game uses only 97,280 bytes of disk space.

Changing your css file to a scss file would allow you to do the trick. An example in Angular would be to use an ngClass and your scss would look like:

 .sidebar {
    height: 100%;
    width: 60px;

    &.is-open {
        width: 150px
    }
} 

For strings, you can use string.c_str() which will return you a const char*, which can be treated as an array, example:

const char* strdata = str.c_str();

for (int i = 0; i < str.length(); ++i)
    cout << i << strdata[i];

Corse-grained services provides broader functionalities as compared to fine-grained service. Depending on the business domain, a single service can be created to serve a single business unit or specialised multiple fine-grained services can be created if subunits are largely independent of each other. Coarse grained service may get more difficult may be less adaptable to change due to its size while fine-grained service may introduce additional complexity of managing multiple services.

Yes you can use them, for example I use them to more easily style groups of data, like this:

thead th { width: 100px; border-bottom: solid 1px #ddd; font-weight: bold; }_x000D_
tbody:nth-child(odd) { background: #f5f5f5;  border: solid 1px #ddd; }_x000D_
tbody:nth-child(even) { background: #e5e5e5;  border: solid 1px #ddd; }

<table>_x000D_
    <thead>_x000D_
        <tr><th>Customer</th><th>Order</th><th>Month</th></tr>_x000D_
    </thead>_x000D_
    <tbody>_x000D_
        <tr><td>Customer 1</td><td>#1</td><td>January</td></tr>_x000D_
        <tr><td>Customer 1</td><td>#2</td><td>April</td></tr>_x000D_
        <tr><td>Customer 1</td><td>#3</td><td>March</td></tr>_x000D_
    </tbody>_x000D_
    <tbody>_x000D_
        <tr><td>Customer 2</td><td>#1</td><td>January</td></tr>_x000D_
        <tr><td>Customer 2</td><td>#2</td><td>April</td></tr>_x000D_
        <tr><td>Customer 2</td><td>#3</td><td>March</td></tr>_x000D_
    </tbody>_x000D_
    <tbody>_x000D_
        <tr><td>Customer 3</td><td>#1</td><td>January</td></tr>_x000D_
        <tr><td>Customer 3</td><td>#2</td><td>April</td></tr>_x000D_
        <tr><td>Customer 3</td><td>#3</td><td>March</td></tr>_x000D_
    </tbody>_x000D_
</table>

You can view an example here. It'll only work in newer browsers, but that's what I'm supporting in my current application, you can use the grouping for JavaScript etc. The main thing is it's a convenient way to visually group the rows to make the data much more readable. There are other uses of course, but as far as applicable examples, this one is the most common one for me.

         static void Main(string[] args)
        {
            int[] arrayname = new int[5];/*arrayname is an array of 5 integer [5] mean in array [0],[1],[2],[3],[4],[5] because array starts with zero*/
            int i, j;


          /*initialize elements of array arrayname*/
            for (i = 0; i < 5; i++)
            {
                arrayname[i] = i + 100;
            }

             /*output each array element value*/
            for (j = 0; j < 5; j++)
            {
                Console.WriteLine("Element and output value [{0}]={1}",j,arrayname[j]);
            }
            Console.ReadKey();/*Obtains the next character or function key pressed by the user.
                                The pressed key is displayed in the console window.*/
        }

You can for example create an instance of List<object>, which implements IEnumerable<object>. Example:

List<object> list = new List<object>();
list.Add(1);
list.Add(4);
list.Add(5);

IEnumerable<object> en = list;
CallFunction(en);

Alternatively one can use the setExtremes method also,

yAxis.setExtremes(0, 100);

Or if only one value is needed to be set, just leave other as null

yAxis.setExtremes(null, 100);

 select p.post_title,m.meta_value sale_price ,n.meta_value   regular_price
    from  wp_postmeta m 
    inner join wp_postmeta n
      on m.post_id  = n.post_id
    inner join wp_posts p
      ON m.post_id=p.id 
    and m.meta_key = '_sale_price'
    and  n.meta_key = '_regular_price'
     AND p.post_type = 'product';



 update  wp_postmeta m 
inner join wp_postmeta n
  on m.post_id  = n.post_id
inner join wp_posts p
  ON m.post_id=p.id 
and m.meta_key = '_sale_price'
and  n.meta_key = '_regular_price'
 AND p.post_type = 'product'
 set m.meta_value = n.meta_value;

If you need to compare an array of objects, this works in all cases:

let arr = [{ id: 1, title: "title1" },{ id: 2, title: "title2" }]
let brr = [{ id: 2, title: "title2" },{ id: 3, title: "title3" }]

const res = arr.filter(f => brr.some(item => item.id === f.id));
console.log(res);

change it to Console (/SUBSYSTEM:CONSOLE) it will work

We can download a specified branch by using following magical command:

git clone -b < branch name > <remote_repo url> 

With JavaScript (here jQuery), you can disable the prev button before submitting the form.

$('form').on('keypress', function(event) {
    if (event.which == 13) {
        $('input[name="prev"]').prop('type', 'button');
    }
});

JSON stands for JavaScript Object Notation. A JSON object is really a string that has yet to be turned into the object it represents.

To add a property to an existing object in JS you could do the following.

object["property"] = value;

or

object.property = value;

If you provide some extra info like exactly what you need to do in context you might get a more tailored answer.

I don't know why

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%'
    AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')

You can write like this:

img{
    width:100%;
    max-width:600px;
}

I think it could be almost any javascript error/typing error in your application. I tried to delete one file content after another and finally found the typing error.

This is pretty must just a copy of that projects demo page and shows uploading a single file on form submit with upload progress.

EDIT: Added passing a model up to the server in the file post.

The form data in the input elements would be sent in the data property of the post and be available as normal form values.

This works and it's deadly simple. As many points as you want:

    private function moveTweets():void {


        var newScale:Number=Scale(meshes.length,50,500,6,2);
        trace("new scale:"+newScale);


        var l:Number=this.meshes.length;
        var tweetMeshInstance:TweetMesh;
        var destx:Number;
        var desty:Number;
        var destz:Number;
        for (var i:Number=0;i<this.meshes.length;i++){

            tweetMeshInstance=meshes[i];

            var phi:Number = Math.acos( -1 + ( 2 * i ) / l );
            var theta:Number = Math.sqrt( l * Math.PI ) * phi;

            tweetMeshInstance.origX = (sphereRadius+5) * Math.cos( theta ) * Math.sin( phi );
            tweetMeshInstance.origY= (sphereRadius+5) * Math.sin( theta ) * Math.sin( phi );
            tweetMeshInstance.origZ = (sphereRadius+5) * Math.cos( phi );

            destx=sphereRadius * Math.cos( theta ) * Math.sin( phi );
            desty=sphereRadius * Math.sin( theta ) * Math.sin( phi );
            destz=sphereRadius * Math.cos( phi );

            tweetMeshInstance.lookAt(new Vector3D());


            TweenMax.to(tweetMeshInstance, 1, {scaleX:newScale,scaleY:newScale,x:destx,y:desty,z:destz,onUpdate:onLookAtTween, onUpdateParams:[tweetMeshInstance]});

        }

    }
    private function onLookAtTween(theMesh:TweetMesh):void {
        theMesh.lookAt(new Vector3D());
    }

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

I just use this for add a image to clipboard in windows.

Yet another solution would be to create a Dictionary<string, object> before calling TextBoxFor and pass that dictionary. In the dictionary, add "disabled" key only if the textbox is to be diabled. Not the neatest solution but simple and straightforward.

An easy way to do it:

var data = '{"result":true,"count":1}';
var json = eval("[" +data+ "]")[0]; // ;)

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

There are three ways to fetch multiple rows returned by PDO statement.

The simplest one is just to iterate over PDOStatement itself:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// iterating over a statement
foreach($stmt as $row) {
    echo $row['name'];
}

another one is to fetch rows using fetch() method inside a familiar while statement:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    echo $row['name'];
}

but for the modern web application we should have our datbase iteractions separated from output and thus the most convenient method would be to fetch all rows at once using fetchAll() method:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// fetching rows into array
$data = $stmt->fetchAll();

or, if you need to preprocess some data first, use the while loop and collect the data into array manually

$result = [];
$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    $result[] = [
        'newname' => $row['oldname'],
        // etc
    ];
}

and then output them in a template:

<ul>
<?php foreach($data as $row): ?>
    <li><?=$row['name']?></li>
<?php endforeach ?>
</ul>

Note that PDO supports many sophisticated fetch modes, allowing fetchAll() to return data in many different formats.

You need add charset in the RequestMapping annotation:

@RequestMapping(path = "/account",  produces = "application/json;charset=UTF-8")

thats all.

Presumably you have reason to be believe that the algorithm for producing Guids is not producing truly random numbers, but is in fact cycling with a period << 2^128.

e.g. RFC4122 method used to derive GUIDs which fixes the values of some bits.

Proof of cycling is going to depend upon the possible size of the period.

For small periods, hash table of hash(GUID) -> GUID with replacement on collision if GUIDs do not match (terminate if they do) might be an approach. Consider also only doing the replacement a random fraction of the time.

Ultimately if the maximum period between collisions is large enough (and isn't known in advance) any method is only going to yield a probability that the collision would be found if it existed.

Note that if the method of generating Guids is clock based (see the RFC), then it may not be possible to determine if collisions exist because either (a) you won't be able to wait long enough for the clock to wrap round, or (b) you can't request enough Guids within a clock tick to force a collision.

Alternatively you might be able to show a statistical relationship between the bits in the Guid, or a correlation of bits between Guids. Such a relationship might make it highly probable that the algorithm is flawed without necessarily being able to find an actual collision.

Of course, if you just want to prove that Guids can collide, then a mathematical proof, not a program, is the answer.

JSON uses the Date.prototype.toISOString function which does not represent local time -- it represents time in unmodified UTC -- if you look at your date output you can see you're at UTC+2 hours, which is why the JSON string changes by two hours, but if this allows the same time to be represented correctly across multiple time zones.

If you want all groups known to the system, I would recommend using getent group instead of parsing /etc/group:

getent group

The reason is that on networked systems, groups may not only read from /etc/group file, but also obtained through LDAP or Yellow Pages (the list of known groups comes from the local group file plus groups received via LDAP or YP in these cases).

If you want just the group names you can use:

getent group | cut -d: -f1

set pagesize 0

alter session set skip_unusable_indexes = true;
spool c:\temp\disable_indexes.sql
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;
spool off
@c:\temp\disable_indexes.sql

Do import...

select 'alter index ' || u.index_name || 
' rebuild online;' from user_indexes u;

Note this assumes that the import is going to happen in the same (sqlplus) session.
If you are calling "imp" it will run in a separate session so you would need to use "ALTER SYSTEM" instead of "ALTER SESSION" (and remember to put the parameter back the way you found it.

My humble take on the subject, a generalization of Alex Martelli's answer, with start() and stop() control:

from threading import Timer

class RepeatedTimer(object):
    def __init__(self, interval, function, *args, **kwargs):
        self._timer     = None
        self.interval   = interval
        self.function   = function
        self.args       = args
        self.kwargs     = kwargs
        self.is_running = False
        self.start()

    def _run(self):
        self.is_running = False
        self.start()
        self.function(*self.args, **self.kwargs)

    def start(self):
        if not self.is_running:
            self._timer = Timer(self.interval, self._run)
            self._timer.start()
            self.is_running = True

    def stop(self):
        self._timer.cancel()
        self.is_running = False

Usage:

from time import sleep

def hello(name):
    print "Hello %s!" % name

print "starting..."
rt = RepeatedTimer(1, hello, "World") # it auto-starts, no need of rt.start()
try:
    sleep(5) # your long-running job goes here...
finally:
    rt.stop() # better in a try/finally block to make sure the program ends!

Features:

• Standard library only, no external dependencies
• start() and stop() are safe to call multiple times even if the timer has already started/stopped
• function to be called can have positional and named arguments
• You can change interval anytime, it will be effective after next run. Same for args, kwargs and even function!

It's always a good idea, and while it's not always required, the Windows standard is to include both.

\n actually represents a Line Feed, or the number 10, and canonically a Line Feed means just "move down one row" on terminals and teletypes.

\r represents CR, a Carriage Return, or the number 13. On Windows, Unix, and most terminals, a CR moves the cursor to the beginning of the line. (This is not the case for 8-bit computers: most of those do advance to the next line with a CR.)

Anyway, some processes, such as the text console, might add a CR automatically when you send an LF. However, since the CR simply moves to the start of the line, there's no harm in sending the CR twice.

On the other hand, dialog boxes, text boxes, and other display elements require both CR and LF to properly start a new line.

Since there's really no downside to sending both, and both are required in some situations, the simplest policy is to use both, if you're not sure.

dim mydate = from cv in mydata.t1s
  select cv.date1 asc

datetime mindata = mydate[0];

I know this is a relatively old thread, but I thought I'd throw what I did out there.

I wanted attribute-mapping to work globally. Either you match the property name (aka default) or you match a column attribute on the class property. I also didn't want to have to set this up for every single class I was mapping to. As such, I created a DapperStart class that I invoke on app start:

public static class DapperStart
{
    public static void Bootstrap()
    {
        Dapper.SqlMapper.TypeMapProvider = type =>
        {
            return new CustomPropertyTypeMap(typeof(CreateChatRequestResponse),
                (t, columnName) => t.GetProperties().FirstOrDefault(prop =>
                    {
                        return prop.Name == columnName || prop.GetCustomAttributes(false).OfType<ColumnAttribute>()
                                   .Any(attr => attr.Name == columnName);
                    }
                ));
        };
    }
}

Pretty simple. Not sure what issues I'll run into yet as I just wrote this, but it works.

find | perl -lne 'print quotemeta' | xargs ls -d

I believe that this will work reliably for any character except line-feed (and I suspect that if you've got line-feeds in your filenames, then you've got worse problems than this). It doesn't require GNU findutils, just Perl, so it should work pretty-much anywhere.

As Authentication vs Authorization puts it:

Authentication is the mechanism whereby systems may securely identify their users. Authentication systems provide an answers to the questions:

• Who is the user?
• Is the user really who he/she represents himself to be?

Authorization, by contrast, is the mechanism by which a system determines what level of access a particular authenticated user should have to secured resources controlled by the system. For example, a database management system might be designed so as to provide certain specified individuals with the ability to retrieve information from a database but not the ability to change data stored in the datbase, while giving other individuals the ability to change data. Authorization systems provide answers to the questions:

• Is user X authorized to access resource R?
• Is user X authorized to perform operation P?
• Is user X authorized to perform operation P on resource R?

Unlike Java, C++ doesn't have a "standard style". Pretty much very company I've ever worked at has its own C++ coding style, and most open source projects have their own styles too. A few coding conventions you might want to look at:

• GNU Coding Standards (mostly C, but mentions C++)
• Google C++ Style Guide
• C++ Coding Standards: 101 Rules, Guidelines, and Best Practices

It's interesting to note that C++ coding standards often specify which parts of the language not to use. For example, the Google C++ Style Guide says "We do not use C++ exceptions". Almost everywhere I've worked has prohibited certain parts of C++. (One place I worked basically said, "program in C, but new and delete are okay"!)

If you want a new one, then do session_destroy() before starting it. To check if its set before starting it, call session_status() :

$status = session_status();
if($status == PHP_SESSION_NONE){
    //There is no active session
    session_start();
}else
if($status == PHP_SESSION_DISABLED){
    //Sessions are not available
}else
if($status == PHP_SESSION_ACTIVE){
    //Destroy current and start new one
    session_destroy();
    session_start();
}

I would avoid checking the global $_SESSION instead of I am calling the session_status() method since PHP implemented this function explicitly to:

Expose session status via new function, session_status This is for (PHP >=5.4.0)

Go to iOS Simulator-> Hardware-> Keyboard -> Uncheck the Connect Hardware Keyboard Option. This will fix the issue.

Use

datatable.select("col1='test'","col1 ASC")

Then before binding your data to the grid or repeater etc, use this

datatable.defaultview.sort()

That will solve your problem.

Yes, -f is the most suitable option for this.

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring

IIRC ...

setSize sets the size of the component.

setPreferredSize sets the preferred size. The Layoutmanager will try to arrange that much space for your component.

It depends on whether you're using a layout manager or not ...

You can also delete all tables from database using only MSSMS UI tools (without using SQL script). Sometimes this way can be more comfortable (especially if it is performed occasionally)

I do this step by step as follows:

1. Select 'Tables' on the database tree (Object Explorer)
2. Press F7 to open Object Explorer Details view
3. In this view select tables which have to be deleted (in this case all of them)
4. Keep pressing Delete until all tables have been deleted (you repeat it as many times as amount of errors due to key constraints/dependencies)

SQL keywords are case insensitive themselves.

Names of tables, columns etc, have a case sensitivity which is database dependent - you should probably assume that they are case sensitive unless you know otherwise (In many databases they aren't though; in MySQL table names are SOMETIMES case sensitive but most other names are not).

Comparing data using =, >, < etc, has a case awareness which is dependent on the collation settings which are in use on the individual database, table or even column in question. It's normal however, to keep collation fairly consistent within a database. We have a few columns which need to store case-sensitive values; they have a collation specifically set.

I would say parsing it is the only way you can really entirely tell. Exception will be raised by python's json.loads() function (almost certainly) if not the correct format. However, the the purposes of your example you can probably just check the first couple of non-whitespace characters...

I'm not familiar with the JSON that facebook sends back, but most JSON strings from web apps will start with a open square [ or curly { bracket. No images formats I know of start with those characters.

Conversely if you know what image formats might show up, you can check the start of the string for their signatures to identify images, and assume you have JSON if it's not an image.

Another simple hack to identify a graphic, rather than a text string, in the case you're looking for a graphic, is just to test for non-ASCII characters in the first couple of dozen characters of the string (assuming the JSON is ASCII).

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

width: 100%

I had to add the CSS class into the asp:DropDownList element

For those looking for a plug-and-play solution on UIImage, I wrote CodyMace's answer as an extension.

Usage: let outlined = UIImage(named: "something")?.outline()

extension UIImage {

    func outline() -> UIImage? {

        let size = CGSize(width: self.size.width, height: self.size.height)
        UIGraphicsBeginImageContext(size)
        let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
        self.draw(in: rect, blendMode: .normal, alpha: 1.0)
        let context = UIGraphicsGetCurrentContext()
        context?.setStrokeColor(red: 0, green: 0, blue: 0, alpha: 1)
        context?.stroke(rect)
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return newImage

    }

}

Here is the script i used and it works like a charm. I used the boolean method Ender suggested as the other ones using only the IE specific script adds something to IE but doesn´t take the original code out.

    <script>runFancy = true;</script>
<!--[if IE]>
<script type="text/javascript">
    runFancy = false;
 </script> // <div>The HTML version for IE went here</div>
<![endif]-->

    // Below is the script used for all other browsers:
    <script src="accmenu/acac1.js" charset="utf-8" type="text/javascript"></script><script>ac1init_doc('',0)</script> 

Here's a simple example that waits for a tread to finish, within the same class. It also makes a call to another class in the same namespace. I included the "using" statements so it can execute as a Windows Forms form as long as you create button1.

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Threading;

namespace ClassCrossCall
{

    public partial class Form1 : Form
    {
        int number = 0; // This is an intentional problem, included
                        // for demonstration purposes
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            button1.Text = "Initialized";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            button1.Text = "Clicked";
            button1.Refresh();
            Thread.Sleep(400);
            List<Task> taskList = new List<Task>();
            taskList.Add(Task.Factory.StartNew(() => update_thread(2000)));
            taskList.Add(Task.Factory.StartNew(() => update_thread(4000)));
            Task.WaitAll(taskList.ToArray());
            worker.update_button(this, number);
        }

        public void update_thread(int ms)
        {
            // It's important to check the scope of all variables
            number = ms; // This could be either 2000 or 4000. Race condition.
            Thread.Sleep(ms);
        }
    }

    class worker
    {
        public static void update_button(Form1 form, int number)
        {
            form.button1.Text = $"{number}";
        }
    }
}

For completeness, also look into the local storage capabilities & sessionStorage of HTML5. These are supported in the latest versions of all modern browsers, and are much easier to use and less fiddly than cookies.

http://www.w3.org/TR/2009/WD-webstorage-20091222/

https://www.w3.org/TR/webstorage/. (second edition)

Here are some sample code for setting and getting the values using sessionStorage and localStorage :

 // HTML5 session Storage
 sessionStorage.setItem("variableName","test");
 sessionStorage.getItem("variableName");


//HTML5 local storage 
localStorage.setItem("variableName","Text");
// Receiving the data:
localStorage.getItem("variableName");

After stumbling around, this worked for me:

df = df.astype(object).where(pd.notnull(df),None)

For what it worth, if anyone has this problem only in VSCode, just restart VSCode and it should fix it. Sometimes, Intellisense seems to mess up with imports or types.
