You can increase the memory allowed to php script by executing the following line above all the codes in the script:

ini_set('memory_limit','-1'); // enabled the full memory available.

And also de allocate the unwanted variables in the script.

One (slightly hacky) way to do it is replace and links that lead away from your site with an AJAX call to the server-side, indicating the user is leaving, then use that same javascript block to take the user to the external site they've requested.

Of course this won't work if the user simply closes the browser window or types in a new URL.

To get around that, you'd potentially need to use Javascript's setTimeout() on the page, making an AJAX call every few seconds (depending on how quickly you want to know if the user has left).

You can use urlib2 and parse the HTML yourself.

Or try Beautiful Soup to do some of the parsing for you.

Calling

if (a == b)

Will work most of the time, but it's not guaranteed to always work, so do not use it.

The most proper way to compare two Integer classes for equality, assuming they are named 'a' and 'b' is to call:

if(a != null && a.equals(b)) {
  System.out.println("They are equal");
}

You can also use this way which is slightly faster.

   if(a != null && b != null && (a.intValue() == b.intValue())) {
      System.out.println("They are equal");
    } 

On my machine 99 billion operations took 47 seconds using the first method, and 46 seconds using the second method. You would need to be comparing billions of values to see any difference.

Note that 'a' may be null since it's an Object. Comparing in this way will not cause a null pointer exception.

For comparing greater and less than, use

if (a != null && b!=null) {
    int compareValue = a.compareTo(b);
    if (compareValue > 0) {
        System.out.println("a is greater than b");
    } else if (compareValue < 0) {
        System.out.println("b is greater than a");
    } else {
            System.out.println("a and b are equal");
    }
} else {
    System.out.println("a or b is null, cannot compare");
}

How to use autoexpect to pipe a password into a command:

These steps are illustrated with an Ubuntu 12.10 desktop. The exact commands for your distribution may be slightly different.

This is dangerous because you risk exposing whatever password you use to anyone who can read the autoexpect script file.

DO NOT expose your root password or power user passwords by piping them through expect like this. Root kits WILL find this in an instant and your box is owned.

EXPECT spawns a process, reads text that comes in then sends text predefined in the script file.

1. Make sure you have expect and autoexpect installed:

   sudo apt-get install expect
   sudo apt-get install expect-dev
   

2. Read up on it:

   man expect
   man autoexpect
   

3. Go to your home directory:

   cd /home/el
   

4. User el cannot chown a file to root and must enter a password:

   touch testfile.txt
   sudo chown root:root testfile.txt 
      [enter password to authorize the changing of the owner]
   

5. This is the password entry we want to automate. Restart the terminal to ensure that sudo asks us for the password again. Go to /home/el again and do this:

   touch myfile.txt
   
   autoexpect -f my_test_expect.exp sudo chown root:root myfile.txt
   
       [enter password which authorizes the chown to root]
   
   autoexpect done, file is my_test_expect.exp
   

6. You have created my_test_expect.exp file. Your super secret password is stored plaintext in this file. This should make you VERY uncomfortable. Mitigate some discomfort by restricting permissions and ownership as much as possible:

   sudo chown el my_test_expect.exp     //make el the owner.
   sudo chmod 700 my_test_expect.exp    //make file only readable by el.
   

7. You see these sorts of commands at the bottom of my_test_expect.exp:

   set timeout -1
   spawn sudo chown root:root myfile.txt
   match_max 100000
   expect -exact "\[sudo\] password for el: "
   send -- "YourPasswordStoredInPlaintext\r"
   expect eof
   

8. You will need to verify that the above expect commands are appropriate. If the autoexpect script is being overly sensitive or not sensitive enough then it will hang. In this case it's acceptable because the expect is waiting for text that will always arrive.

9. Run the expect script as user el:

   expect my_test_expect.exp 
   spawn sudo chown root:root myfile.txt
   [sudo] password for el: 
   

10. The password contained in my_test_expect.exp was piped into a chown to root by user el. To see if the password was accepted, look at myfile.txt:

    ls -l
    -rw-r--r--  1 root root          0 Dec  2 14:48 myfile.txt
    

It worked because it is root, and el never entered a password. If you expose your root, sudo, or power user password with this script, then acquiring root on your box will be easy. Such is the penalty for a security system that lets everybody in no questions asked.

DatabaseMetaData dbm = con.getMetaData();
// check if "employee" table is there
ResultSet tables = dbm.getTables(null, null, "employee", null);
if (tables.next()) {
  // Table exists
}
else {
  // Table does not exist
}

They are the complete opposite of each other.

JSON.parse() is used for parsing data that was received as JSON; it deserializes a JSON string into a JavaScript object.

JSON.stringify() on the other hand is used to create a JSON string out of an object or array; it serializes a JavaScript object into a JSON string.

Try doing something like the following in main:

public static void main(String[] args) {
     PropertyConfigurator.configure(args[0]);
    //... your code

you need to tell log4j what its configuration should be.

something like....

SELECT f.*
      ,a1.city as from
      ,a2.city as to
FROM flights f
INNER JOIN airports a1
ON f.fairport = a1. code
INNER JOIN airports a2
ON f.tairport = a2. code

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

A comment to the "addPath" script; When supplying a path with spaces, it throws up.

Example: call addPath "c:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin"

yields: 'Files' is not recognized as an internal or external command, operable program or batch file.

A primary key has the semantic of identifying the row of a database. Therefore there can be only one primary key for a given table, while there can be many unique keys.

Also for the same reason a primary key cannot be NULL (at least in Oracle, not sure about other databases)

Since it identifies the row it should never ever change. Changing primary keys are bound to cause serious pain and probably eternal damnation.

Therefor in most cases you want some artificial id for primary key which isn't used for anything but identifying single rows in the table.

Unique keys on the other hand may change as much as you want.

I ended up combining urlTree with location.go

const urlTree = this.router.createUrlTree([], {
       relativeTo: this.route,
       queryParams: {
           newParam: myNewParam,
       },
       queryParamsHandling: 'merge',
    });

    this.location.go(urlTree.toString());

Not sure if toString can cause problems, but unfortunately location.go, seems to be string based.

You can use mmc:

1. Start / Run. Type "mmc".
2. File / Add/Remove Snap-in... Click "Add..."
3. Find "Services" and click "Add"
4. Select "Another computer:" and type the host name / IP address of the remote machine. Click Finish, Close, etc.

At that point you will be able to manage services as if they were on your local machine.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

Aggregate in a subquery derived table and then join to it.

 Select Date, User, Status, Notes 
    from [SOMETABLE]
    inner join 
    (
        Select max(Date) as LatestDate, [User]
        from [SOMETABLE]
        Group by User
    ) SubMax 
    on [SOMETABLE].Date = SubMax.LatestDate
    and [SOMETABLE].User = SubMax.User 

If you use the OOP method of inserting, you don't need to worry about mass-action/fillable properties:

$user = new User;
$user->username = 'Stevo';
$user->email = '[email protected]';
$user->password = '45678';
$user->save();

Why not call the $('.input-group.date').datepicker("remove"); when the select statement is changed then set your datepicker view then call the $('.input-group.date').datepicker("update");

div.abc.xyz {
    /* rules go here */
}

... or simply:

.abc.xyz {
    /* rules go here */
}

A "connection reset" error message generally means that the other side has aborted the connection during the attempt to create a connection (the handshake). This has a lot of possible causes. A bug in the JDBC driver, a timeout at the DB side, a restart of the database, the DB being run out of available connections, poor network quality, bad virusscanner/firewall/proxy, etc.

As it happens intermittely, a bug in the JDBC driver can be less or more excluded. Left behind the remaining possible causes. I suggest to start with looking in the logs of the DB server.

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

Do not use Jo Liss's resumer answer. It will work in most cases, but in my case it lost me a good 4 or 5 hours bug finding. There is no need for third party modules to do this.

NEW ANSWER:

var Readable = require('stream').Readable

var s = new Readable()
s.push('beep')    // the string you want
s.push(null)      // indicates end-of-file basically - the end of the stream

This should be a fully compliant Readable stream. See here for more info on how to use streams properly.

OLD ANSWER: Just use the native PassThrough stream:

var stream = require("stream")
var a = new stream.PassThrough()
a.write("your string")
a.end()

a.pipe(process.stdout) // piping will work as normal
/*stream.on('data', function(x) {
   // using the 'data' event works too
   console.log('data '+x)
})*/
/*setTimeout(function() {
   // you can even pipe after the scheduler has had time to do other things
   a.pipe(process.stdout) 
},100)*/

a.on('end', function() {
    console.log('ended') // the end event will be called properly
})

Note that the 'close' event is not emitted (which is not required by the stream interfaces).

To stop a for loop early in JavaScript, you use break:

var remSize = [], 
    szString,
    remData,
    remIndex,
    i;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // Set a default if we don't find it
for (i = 0; i < remSize.length; i++) {      
     // I'm looking for the index i, when the condition is true
     if (remSize[i].size === remData.size) {
          remIndex = i;
          break;       // <=== breaks out of the loop early
     }
}

If you're in an ES2015 (aka ES6) environment, for this specific use case, you can use Array#findIndex (to find the entry's index) or Array#find (to find the entry itself), both of which can be shimmed/polyfilled:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = remSize.findIndex(function(entry) {
     return entry.size === remData.size;
});

Array#find:

var remSize = [], 
    szString,
    remData,
    remEntry;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remEntry = remSize.find(function(entry) {
     return entry.size === remData.size;
});

Array#findIndex stops the first time the callback returns a truthy value, returning the index for that call to the callback; it returns -1 if the callback never returns a truthy value. Array#find also stops when it finds what you're looking for, but it returns the entry, not its index (or undefined if the callback never returns a truthy value).

If you're using an ES5-compatible environment (or an ES5 shim), you can use the new some function on arrays, which calls a callback until the callback returns a truthy value:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // <== Set a default if we don't find it
remSize.some(function(entry, index) {
    if (entry.size === remData.size) {
        remIndex = index;
        return true; // <== Equivalent of break for `Array#some`
    }
});

If you're using jQuery, you can use jQuery.each to loop through an array; that would look like this:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // <== Set a default if we don't find it
jQuery.each(remSize, function(index, entry) {
    if (entry.size === remData.size) {
        remIndex = index;
        return false; // <== Equivalent of break for jQuery.each
    }
});

Try pasting in the SVN URL into your browser's Address bar. You'll likely see that you cannot connect because of some issue with the URL. I had this issue just today and the problem was that I had mistyped the port number, but as others have noted it could also be a case-sensitivity issue, proxy settings, or other connection-level issues.

I thought this might be useful to someone:

in chrome version 32, a 2-pixels border automatically appears around iframes without the seamless attribute. It can be easily removed by adding this CSS rule:

iframe:not([seamless]) { border:none; }

Chrome uses the same selector with these default user-agent styles:

iframe:not([seamless]) {
  border: 2px inset;
  border-image-source: initial;
  border-image-slice: initial;
  border-image-width: initial;
  border-image-outset: initial;
  border-image-repeat: initial;
}

The article previously mentioned is good. http://forums.oracle.com/forums/thread.jspa?threadID=191750 (as far as it goes)

If this is not something that runs frequently (don't do it on your home page), you can turn off connection pooling.

There is one other "gotcha" that is not mentioned in the article. If the first thing you try to do with the connection is call a stored procedure, ODP will HANG!!!! You will not get back an error condition to manage, just a full bore HANG! The only way to fix it is to turn OFF connection pooling. Once we did that, all issues went away.

Pooling is good in some situations, but at the cost of increased complexity around the first statement of every connection.

If the error handling approach is so good, why don't they make it an option for ODP to handle it for us????

git gui provides this functionality under the diff view. Just right click the line(s) you're interested in and you should see a "stage this line to commit" menu item.

OK, here are the things that come into mind:

• Your WCF service presumably running on IIS must be running under the security context that has the privilege that calls the Web Service. You need to make sure in the app pool with a user that is a domain user - ideally a dedicated user.
• You can not use impersonation to use user's security token to pass back to ASMX using impersonation since my WCF web service calls another ASMX web service, installed on a **different** web server
• Try changing Ntlm to Windows and test again.

OK, a few words on impersonation. Basically it is a known issue that you cannot use the impersonation tokens that you got to one server, to pass to another server. The reason seems to be that the token is a kind of a hash using user's password and valid for the machine generated from so it cannot be used from the middle server.

UPDATE

Delegation is possible under WCF (i.e. forwarding impersonation from a server to another server). Look at this topic here.

var objResponse1 =

I'm guessing your code failed BEFORE import sys, so it can't find it when you handle the exception.

Also, you should indent the your code whithin the try block.

try:

import sys
# .. other safe imports
try:
    import numpy as np
    # other unsafe imports
except ImportError:
    print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
    sys.exit()

FYI: In .NET, Hashtable is thread safe for use by multiple reader threads and a single writing thread, while in Dictionary public static members are thread safe, but any instance members are not guaranteed to be thread safe.

We had to change all our Dictionaries back to Hashtable because of this.

Make sure the .ico file isn't corrupted as well. I got the same error which went away when I tried a different .ico file.

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

If you want to fetch particular element/node or tag in loop for e.g.

<p class="weekday" data-today="monday">Monday</p>
<p class="weekday" data-today="tuesday">Tuesday</p>
<p class="weekday" data-today="wednesday">Wednesday</p>
<p class="weekday" data-today="thursday">Thursday</p>

So, from above code loop is executed and we want particular field to select for that we have to use jQuery selection that can select only expecting element from above loop so, code will be

$('.weekdays:eq(n)');

e.g.

$('.weekdays:eq(0)');

as well as by other method

$('.weekday').find('p').first('.weekdays').next()/last()/prev();

but first method is more efficient when HTML <tag> has unique class name.

NOTE:Second method is use when their is no class name in target element or node.

The .bashrc file is in your user home directory (~/.bashrc or ~vagrant/.bashrc both resolve to the same path), inside the VM's filesystem. This file is invisible on the host machine, so you can't use any Windows editors to edit it directly.

You have two simple choices:

1. Learn how to use a console-based text editor. My favourite is vi (or vim), which takes 15 minutes to learn the basics and is much quicker for simple edits than anything else.

   vi .bashrc

2. Copy .bashrc out to /vagrant (which is a shared directory) and edit it using your Windows editors. Make sure not to save it back with any extensions.

   cp .bashrc /vagrant ... edit using your host machine ... cp /vagrant/.bashrc .

I'd recommend getting to know the command-line based editors. Once you're working inside the VM, it's best to stay there as otherwise you might just get confused.

You (the vagrant user) are the owner of your home .bashrc so you do have permissions to edit it.

Once edited, you can execute it by typing source .bashrc I prefer to logout and in again (there may be more than one file executed on login).

            for ($i = 1; $i <= $retries; ++$i)
            {
                $result = curl_exec($curl);

                if (($i == $retries) || ($result !== false))
                {
                    break;
                }

                usleep(pow(2, $i - 2) * 1000000);
            }
        }

        curl_close($curl);
    }

    return $result;
}

And pass this as $cookie parameter:

$cookie_jar = tempnam('/tmp','cookie');

Stop this error you have to follow this simple steps

1. Open Visual Studio
2. Select option debug from the top
3. Select Options
4. In Option Select debugging under debugging select General
5. In General Select check box "Automatically close the console when debugging stop"
6. Save it

Then Run the code by using Shortcut key Ctrl+f5

**Other wise it still show error when you run it direct

You can use ArgbEvaluatorCompat class above API 11.

implementation 'com.google.android.material:material:1.0.0' 


ValueAnimator colorAnim = ValueAnimator.ofObject(new ArgbEvaluatorCompat(), startColor, endColor);
colorAnim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            mTargetColor = (int) animation.getAnimatedValue();
        }
    });
colorAnim.start();

Create a mutable map without initial value:

scala> var d= collection.mutable.Map[Any, Any]()
d: scala.collection.mutable.Map[Any,Any] = Map()

Create a mutable map with initial values:

scala> var d= collection.mutable.Map[Any, Any]("a"->3,1->234,2->"test")
d: scala.collection.mutable.Map[Any,Any] = Map(2 -> test, a -> 3, 1 -> 234)

Update existing key-value:

scala> d("a")= "ABC"

Add new key-value:

scala> d(100)= "new element"

Check the updated map:

scala> d
res123: scala.collection.mutable.Map[Any,Any] = Map(2 -> test, 100 -> new element, a -> ABC, 1 -> 234)

DELETE FROM table_name WHERE id BETWEEN 1 AND 256;

Try This.

also you can use "readonly"

<select id="xxx" name="xxx" class="input-medium" readonly>

Building up on Paul Burke's answer I faced many problems resolving external SD card's URI path as most of the suggested "built-in" functions return paths which do not get resolved to files.

However, this is my approach of his // TODO handle non-primary volumes.

String resolvedPath = "";
File[] possibleExtSdComposites = context.getExternalFilesDirs(null);
for (File f : possibleExtSdComposites) {
    // Reset final path
    resolvedPath = "";

    // Construct list of folders
    ArrayList<String> extSdSplit = new ArrayList<>(Arrays.asList(f.getPath().split("/")));

    // Look for folder "<your_application_id>"
    int idx = extSdSplit.indexOf(BuildConfig.APPLICATION_ID);

    // ASSUMPTION: Expected to be found at depth 2 (in this case ExtSdCard's root is /storage/0000-0000/) - e.g. /storage/0000-0000/Android/data/<your_application_id>/files
    ArrayList<String> hierarchyList = new ArrayList<>(extSdSplit.subList(0, idx - 2));

    // Construct list containing full possible path to the file
    hierarchyList.add(tail);
    String possibleFilePath = TextUtils.join("/", hierarchyList);

    // If file is found --> success
    if (idx != -1 && new File(possibleFilePath).exists()) {
        resolvedPath = possibleFilePath;
        break;
    }
}

if (!resolvedPath.equals("")) {
    return resolvedPath;
} else {
    return null;
}

Note it depends on hierarchy which might be different on every phone manufacturer - I have not tested them all (it worked well so far on Xperia Z3 API 23 and Samsung Galaxy A3 API 23).

Please confirm if it does not perform well elsewhere.

A solution based on a comment by kbjorklu is:

bool isNumber(const std::string& s)
{
   return !s.empty() && s.find_first_not_of("-.0123456789") == std::string::npos;
}

As with David Rector's answer it is not robust to strings with multiple dots or minus signs, but you can remove those characters to just check for integers.

However, I am partial to a solution, based on Ben Voigt's solution, using strtod in cstdlib to look decimal values, scientific/engineering notation, hexidecimal notation (C++11), or even INF/INFINITY/NAN (C++11) is:

bool isNumberC(const std::string& s)
{
    char* p;
    strtod(s.c_str(), &p);
    return *p == 0;
}

I agree with Ahmed and RavinderSingh13 I had a similar problem and found that a white space was just before "#!/bin/bash" at the first line of some of my scripts. I never understood how this space appeared but all my script has at least one space at beginning of any line

take a look at this code

<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2"  /><br />
Answer 3 <input type="radio" name="ans" value="ans3"  /><br />
Answer 4 <input type="radio" name="ans" value="ans4"  /><br />
<input type="submit" value="submit" />
</form>

php

<?php 
if(isset($_POST['submit'])){
if(isset( $_POST['ans'])){  
echo "This is the value you are selected".$_POST['ans'];          
}         
}
?>

This happens when you do not include a message when you try to commit using:

git commit

It launches an editor environment. Quit it by typing :q! and hitting enter.

It's going to take you back to the terminal without committing, so make sure to try again, this time pass in a message:

git commit -m 'Initial commit'

size_t is the type used to represent sizes (as its names implies). Its platform (and even potentially implementation) dependent, and should be used only for this purpose. Obviously, representing a size, size_t is unsigned. Many stdlib functions, including malloc, sizeof and various string operation functions use size_t as a datatype.

An int is signed by default, and even though its size is also platform dependant, it will be a fixed 32bits on most modern machine (and though size_t is 64 bits on 64-bits architecture, int remain 32bits long on those architectures).

To summarize : use size_t to represent the size of an object and int (or long) in other cases.

I have a site where a logging-script writes a new line of text to a textfile after an action from the user, who can be using any OS.

Using PHP_EOL don't seem to be optimal in this case. If the user is on Mac OS and writes to the textfile it will put \n. When opening the textfile on a windows computer it doesn't show a line break. For this reason i use "\r\n" instead which works when opening the file on any OS.

It is in the dist folder inside of the project, but only if "Compress WAR File" in the project settings dialog ( build / packaging) ist checked. Before I checked this checkbox there was no dist folder.

In the Repository Browser of TortoiseSVN, find the branch that you want to create the new branch from. Right-click, Copy To.... and enter the new branch path. Now you can "switch" your local WC to that branch.

Make sure your drawables for the menu are in the correct folder, mine where put in drawablev21 hence this caused a nullpointer to the resource.

Fixed it buy moving my icons to drawables folder

if you add a jpg,png,pdf picture, you should use pdflatex to compile it.

For me, this error "Experimental support for decorators is a feature that is subject to change in a future release. (etc)" only happened in VS Code in an Angular project and only when creating a new Service.

The solution above: "In Visual Code Studio Go to File >> Preferences >> Settings, Search "decorator" in search field and Checking the option JavaScript › Implicit Project Config: Experimental Decorators" solved the problem.

Also, stopping the ng serve in the terminal window and restarting it made the error disappear after recompile.

Java ships in 2 versions: JRE & SDK (used to be called JDK)

The JRE in addition to not containing the compiler, also doesn't contain all of the libraries available in the JDK (tools.jar is one of them)

When you download Java at: http://java.sun.com/javase/downloads/index.jsp, make sure to select the JDK version and install it. If you have both a JDK & JRE, make sure that ANT is using the JDK, you can check JAVA_HOME (environment variable), and on the commandline if you do "javac -version" you should get a version description.

z-Index is not correct. It works initially, but multiple dialogs will continue to float underneath the one you altered with z-index. No good.

As suggested by @EboMike I saved the bitmap in a file named myImage in the internal storage of my application not accessible my other apps. Here's the code of that part:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

Bitmap bitmap = BitmapFactory.decodeStream(context
                    .openFileInput("myImage"));//here context can be anything like getActivity() for fragment, this or MainActivity.this

Note A lot of checking for null and scaling bitmap's is ommited.

You can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:

Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:

Hope this helps.

This should work:

window.onload = function() {
  document.getElementById('about').className = 'expand';
};

Or if you're using jQuery:

$(function() {
  $('#about').addClass('expand');
});

Since this is an open-ended question, I will just give you an idea of how I would go about implementing something like this myself.

<span class="inputname">
    Project Images:
    <a href="#" class="add_project_file">
        <img src="images/add_small.gif" border="0" />
    </a>
</span>

<ul class="project_images">
    <li><input name="upload_project_images[]" type="file" /></li>
</ul>

Wrapping the file inputs inside li elements allows to easily remove the parent of our 'remove' links when clicked. The jQuery to do so is close to what you have already:

// Add new input with associated 'remove' link when 'add' button is clicked.
$('.add_project_file').click(function(e) {
    e.preventDefault();

    $(".project_images").append(
        '<li>'
      + '<input name="upload_project_images[]" type="file" class="new_project_image" /> '
      + '<a href="#" class="remove_project_file" border="2"><img src="images/delete.gif" /></a>'
      + '</li>');
});

// Remove parent of 'remove' link when link is clicked.
$('.project_images').on('click', '.remove_project_file', function(e) {
    e.preventDefault();

    $(this).parent().remove();
});

Here's an example of creating and using an event with C#

using System;

namespace Event_Example
{
    //First we have to define a delegate that acts as a signature for the
    //function that is ultimately called when the event is triggered.
    //You will notice that the second parameter is of MyEventArgs type.
    //This object will contain information about the triggered event.
    public delegate void MyEventHandler(object source, MyEventArgs e);

    //This is a class which describes the event to the class that recieves it.
    //An EventArgs class must always derive from System.EventArgs.
    public class MyEventArgs : EventArgs
    {
        private string EventInfo;
        public MyEventArgs(string Text)
        {
            EventInfo = Text;
        }
        public string GetInfo()
        {
            return EventInfo;
        }
    }

    //This next class is the one which contains an event and triggers it
    //once an action is performed. For example, lets trigger this event
    //once a variable is incremented over a particular value. Notice the
    //event uses the MyEventHandler delegate to create a signature
    //for the called function.
    public class MyClass
    {
        public event MyEventHandler OnMaximum;
        private int i;
        private int Maximum = 10;
        public int MyValue
        {
            get
            {
                return i;
            }
            set
            {
                if(value <= Maximum)
                {
                    i = value;
                }
                else
                {
                    //To make sure we only trigger the event if a handler is present
                    //we check the event to make sure it's not null.
                    if(OnMaximum != null)
                    {
                        OnMaximum(this, new MyEventArgs("You've entered " +
                            value.ToString() +
                            ", but the maximum is " +
                            Maximum.ToString()));
                    }
                }
            }
        }
    }

    class Program
    {
        //This is the actual method that will be assigned to the event handler
        //within the above class. This is where we perform an action once the
        //event has been triggered.
        static void MaximumReached(object source, MyEventArgs e)
        {
            Console.WriteLine(e.GetInfo());
        }

        static void Main(string[] args)
        {
            //Now lets test the event contained in the above class.
            MyClass MyObject = new MyClass();
            MyObject.OnMaximum += new MyEventHandler(MaximumReached);

            for(int x = 0; x <= 15; x++)
            {
                MyObject.MyValue = x;
            }

            Console.ReadLine();
        }
    }
}

It's usually in your MySQL installation folder like in C:\Program Files\MySQL\MySQL Server 5.5\my.ini or C:\xampp\mysql\bin

If it's not there, it's highly possible that you have none, and that MySQL is just loading default values.

You might have to enable hidden Files and Folders to see it. Go to Folder Options: in any folder, go to the top horizontal main text menu >> Tools >> Folder Options. Enable 'View Hidden Files and Folders', and 'View Protected System Files', save & exit

You can use the groupby command, if you already have some labels for your data.

 out_list = [group[1] for group in in_series.groupby(label_series.values)]

Here's a detailed example:

Let's say we want to partition a pd series using some labels into a list of chunks For example, in_series is:

2019-07-01 08:00:00   -0.10
2019-07-01 08:02:00    1.16
2019-07-01 08:04:00    0.69
2019-07-01 08:06:00   -0.81
2019-07-01 08:08:00   -0.64
Length: 5, dtype: float64

And its corresponding label_series is:

2019-07-01 08:00:00   1
2019-07-01 08:02:00   1
2019-07-01 08:04:00   2
2019-07-01 08:06:00   2
2019-07-01 08:08:00   2
Length: 5, dtype: float64

Run

out_list = [group[1] for group in in_series.groupby(label_series.values)]

which returns out_list a list of two pd.Series:

[2019-07-01 08:00:00   -0.10
2019-07-01 08:02:00   1.16
Length: 2, dtype: float64,
2019-07-01 08:04:00    0.69
2019-07-01 08:06:00   -0.81
2019-07-01 08:08:00   -0.64
Length: 3, dtype: float64]

Note that you can use some parameters from in_series itself to group the series, e.g., in_series.index.day

protected void grvSecondaryLocations_RowEditing(object sender, GridViewEditEventArgs e)  
{  
    grvSecondaryLocations.EditIndex = e.NewEditIndex;  

    DropDownList ddlPbx = (DropDownList)(grvSecondaryLocations.Rows[grvSecondaryLocations.EditIndex].FindControl("ddlPBXTypeNS"));
    if (ddlPbx != null)  
    {  
        ddlPbx.DataSource = _pbxTypes;  
        ddlPbx.DataBind();  
    }  

    .... (more stuff)  
}

If you want to generate multiple random subsets of rows, for example if your doing RANSAC.

num_pop = 10
num_samples = 2
pop_in_sample = 3
rows_to_sample = np.random.random([num_pop, 5])
random_numbers = np.random.random([num_samples, num_pop])
samples = np.argsort(random_numbers, axis=1)[:, :pop_in_sample]
# will be shape [num_samples, pop_in_sample, 5]
row_subsets = rows_to_sample[samples, :]

I need to make a POST request via Curl from the command line. Data for this request is located in a file...

All you need to do is have the --data argument start with a @:

curl -H "Content-Type: text/xml" --data "@path_of_file" host:port/post-file-path

For example, if you have the data in a file called stuff.xml then you would do something like:

curl -H "Content-Type: text/xml" --data "@stuff.xml" host:port/post-file-path

The stuff.xml filename can be replaced with a relative or full path to the file: @../xml/stuff.xml, @/var/tmp/stuff.xml, ...

You declared them at the start of the method, but you never initialized them. Initializing would be setting them equal to a value, such as:

int a = 0;
int b = 0;

You have empty $entry_database variable. As you see in error: ListEmail, Title FROM WHERE ID bewteen FROM and WHERE should be name of table. Proper syntax of SELECT:

SELECT columns FROM table [optional things as WHERE/ORDER/GROUP/JOIN etc]

which in your way should become:

SELECT ID, ListStID, ListEmail, Title FROM some_table_you_got WHERE ID = '4'

Technically, I have seen HTTP GET will have issues if the URL length goes beyond 2000 characters. In that case, it's better to use HTTP POST or split the URL.

Do you know View.getViewTreeObserver().addOnGlobalLayoutListener()

By this you can calculate the sizes.

I achieve your UI effect by GridView:

GridView g;
g.setNumColumns(2);
g.setStretchMode(GridView.STRETCH_SPACING_UNIFORM);

Null is used in databases to represent "no record" or "no information". So you might have a bit field that describes "does this user want to be sent e-mails by us", where True means they do, False means they don't want to be sent anything, but Null would mean that you don't know. They can come about through outer joins and suchlike.

The logical implications of Null are often different - in some languages NULL is not equal to anything, so if(a == NULL) will always be false.

So personally I'd always initialise a boolean to FALSE, and initialising one to NULL would look a bit icky (even in C where the two are both just 0... just a style thing).

Haven't you heard about the Comparable interface being implemented by String ? If no, try to use

"abcda".compareTo("abcza")

And it will output a good root for a solution to your problem.

If you're willing to go the way of the preprocessor abuse, Boost.Preprocessor can help you.

    #include <boost/preprocessor/seq/for_each.hpp>

    #define CASE_case(ign, ign2, n) case n:

    #define CASES(seq) \
        BOOST_PP_SEQ_FOR_EACH(CASE_case, ~, seq)

    CASES((1)(3)(15)(13))

Running this through gcc with -E -P to only run the preprocessor, the expansion of CASES gives:

    case 1: case 3: case 15: case 13:

Note that this probably wouldn't pass a code review (wouldn't where I work!) so I recommend it be constrained to personal use.

It should also be possible to create a CASE_RANGE(1,5) macro to expand to

    case 1: case 2: case 3: case 4: case 5:

for you as well.

You can convert both values to upper or lowercase using the upper or lower functions:

Select * from table where upper(table.name) like upper('IgNoreCaSe')

or

Select * from table where lower(table.name) like lower('IgNoreCaSe');

you can use ipinfodb after getting your api key you can query for a location against a specific ip like this http://api.ipinfodb.com/v2/ip_query.php?key=" + apiKey + "&ip=" + ip + "&output=xml you can then then extract the location from the xml response

If you can stand adding one dependency to your project there's the great blob-util npm package that provides a handy base64StringToBlob function. Once added to your package.json you can use it like this:

import { base64StringToBlob } from 'blob-util';

const contentType = 'image/png';
const b64Data = 'iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==';

const blob = base64StringToBlob(b64Data, contentType);

// Do whatever you need with your blob...

The gem env lists where gems can be installed, but this can be 10 or more locations. If you want to know where a particular gem is installed, you can execute:

First, to describe dynamic cast in C terms, we have to represent classes in C. Classes with virtual functions use a "VTABLE" of pointers to the virtual functions. Comments are C++. Feel free to reformat and fix compile errors...

// class A { public: int data; virtual int GetData(){return data;} };
typedef struct A { void**vtable; int data;} A;
int AGetData(A*this){ return this->data; }
void * Avtable[] = { (void*)AGetData };
A * newA() { A*res = malloc(sizeof(A)); res->vtable = Avtable; return res; }

// class B : public class A { public: int moredata; virtual int GetData(){return data+1;} }
typedef struct B { void**vtable; int data; int moredata; } B;
int BGetData(B*this){ return this->data + 1; }
void * Bvtable[] = { (void*)BGetData };
B * newB() { B*res = malloc(sizeof(B)); res->vtable = Bvtable; return res; }

// int temp = ptr->GetData();
int temp = ((int(*)())ptr->vtable[0])();

Then a dynamic cast is something like:

// A * ptr = new B();
A * ptr = (A*) newB();
// B * aB = dynamic_cast<B>(ptr);
B * aB = ( ptr->vtable == Bvtable ? (B*) aB : (B*) 0 );

You can always check this maintained list to timezones

https://www.php.net/manual/en/function.date.php

Expanding on the answer using this:

body {
    width: calc(100vw - 17px);
}

One commentor suggested adding left-padding as well to maintain the centering:

body {
    padding-left: 17px;
    width: calc(100vw - 17px);
}

But then things don't look correct if your content is wider than the viewport. To fix that, you can use media queries, like this:

@media screen and (min-width: 1058px) {
    body {
        padding-left: 17px;
        width: calc(100vw - 17px);
    }
}

Where the 1058px = content width + 17 * 2

This lets a horizontal scrollbar handle the x overflow and keeps the centered content centered when the viewport is wide enough to contain your fixed-width content

Most of you already know this by now, but I am posting this, just incase, some of you are still struggling with JSON in iOS6+.

In iOS6 and later, we have the NSJSONSerialization Class that is fast and has no dependency on including "outside" libraries.

NSDictionary *result = [NSJSONSerialization JSONObjectWithData:[resultStr dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil]; 

This is the way iOS6 and later can now parse JSON efficiently.The use of SBJson is also pre-ARC implementation and brings with it those issues too if you are working in an ARC environment.

I hope this helps!

Store all the to be deleted ID's into a table. Then there are 3 ways. 1) loop through all the ID's in the table, then delete one row at a time for X commit interval. X can be a 100 or 1000. It works on OLTP environment and you can control the locks.

2) Use Oracle Bulk Delete

3) Use correlated delete query.

Single query is usually faster than multiple queries because of less context switching, and possibly less parsing.

You use dependency injection when you exactly know what type of objects you require at this point of time. While in case of factory pattern, you just delegate the process of creating objects to factory as you are unclear of what exact type of objects you require.

You need to add:

 #include <cstdlib>

in order for the compiler to see the prototype for system().

Here's another option. It works by putting an ActiveX ComboBox on top of the cell with validation enabled, and then providing autocomplete in the ComboBox instead.

Option Explicit

' Autocomplete - replacing validation lists with ActiveX ComboBox
'
' Usage:
'   1. Copy this code into a module named m_autocomplete
'   2. Go to Tools / References and make sure "Microsoft Forms 2.0 Object Library" is checked
'   3. Copy and paste the following code to the worksheet where you want autocomplete

The event must be cancelable. Adding an if statement solves this issue.

if (e.cancelable) {
   e.preventDefault();
}

In your code you should put it here:

if (this.isSwipe(swipeThreshold) && e.cancelable) {
   e.preventDefault();
   e.stopPropagation();
   swiping = true;
}

distcp command use for copying from one cluster to another cluster in parallel. You have to set the path for namenode of src and path for namenode of dst, internally it use mapper.

Example:

$ hadoop distcp <src> <dst>

there few options you can set for distcp

-m for no. of mapper for copying data this will increase speed of copying.

-atomic for auto commit the data.

-update will only update data that is in old version.

There are generic command for copying files in hadoop are -cp and -put but they are use only when the data volume is less.

<div class="tabbable">
<ul class="nav nav-tabs">
    <li class="active"><a href="#aaa" data-toggle="tab">AAA</a></li>
    <li><a href="#bbb" data-toggle="tab">BBB</a></li>
    <li><a href="#ccc" data-toggle="tab">CCC</a></li>
</ul>
<div class="tab-content" id="tabs">
    <div class="tab-pane fade active in" id="aaa">...Content...</div>
    <div class="tab-pane" id="bbb">...Content...</div>
    <div class="tab-pane" id="ccc">...Content...</div>
</div>
</div>   

Add active class to any li element you want to be active after page load. And also adding active class to content div is needed ,fade in classes are useful for a smooth transition.

Let's say you have 2 tables, one with a Master set (eg. Employees) and one with a child set (eg. Dependents) and you're wanting to get rid of all the rows of data in the Dependents table that cannot key up with any rows in the Master table.

delete from Dependents where EmpID in (
select d.EmpID from Employees e 
    right join Dependents d on e.EmpID = d.EmpID
    where e.EmpID is null)

The point to notice here is that you're just collecting an 'array' of EmpIDs from the join first, the using that set of EmpIDs to do a Deletion operation on the Dependents table.

The examples above are a bit out of date. One new example is here:

import pyhs2 as hive
import getpass
DEFAULT_DB = 'default'
DEFAULT_SERVER = '10.37.40.1'
DEFAULT_PORT = 10000
DEFAULT_DOMAIN = 'PAM01-PRD01.IBM.COM'

u = raw_input('Enter PAM username: ')
s = getpass.getpass()
connection = hive.connect(host=DEFAULT_SERVER, port= DEFAULT_PORT, authMechanism='LDAP', user=u + '@' + DEFAULT_DOMAIN, password=s)
statement = "select * from user_yuti.Temp_CredCard where pir_post_dt = '2014-05-01' limit 100"
cur = connection.cursor()

cur.execute(statement)
df = cur.fetchall() 

In addition to the standard python program, a few libraries need to be installed to allow Python to build the connection to the Hadoop databae.

1.Pyhs2, Python Hive Server 2 Client Driver

2.Sasl, Cyrus-SASL bindings for Python

3.Thrift, Python bindings for the Apache Thrift RPC system

4.PyHive, Python interface to Hive

Remember to change the permission of the executable

chmod +x test_hive2.py ./test_hive2.py

As far as your question goes: no, if activating from .ini is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap, yum install php-soap). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).

In general, the double-dash --switches are designed to be used when recompiling PHP from scratch.

You would download the PHP source package (as a compressed .tgz tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script

./configure --prefix ...

The configure command used by your PHP may be shown with phpinfo(). Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap will then enable SOAP in addition to everything else.

That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype, gd, libjpeg, XML, expat, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg installed might not be enough, and you might need libjpeg-dev also).

I have to keep a separate virtual machine with everything installed for my recompilation purposes.

This expression will force the first letter to be alphabetic and the remaining characters to be alphanumeric or any of the following special characters: @,#,%,&,*

^[A-Za-z][A-Za-z0-9@#%&*]*$

protocol CustomError : Error {

    var localizedTitle: String
    var localizedDescription: String

}

enum RequestError : Int, CustomError {

    case badRequest         = 400
    case loginFailed        = 401
    case userDisabled       = 403
    case notFound           = 404
    case methodNotAllowed   = 405
    case serverError        = 500
    case noConnection       = -1009
    case timeOutError       = -1001

}

func anything(errorCode: Int) -> CustomError? {

      return RequestError(rawValue: errorCode)
}

a do while loop would be a nice way to wait for the user input. Like this:

int main() 
{

 do 
 {
   cout << '\n' << "Press a key to continue...";
 } while (cin.get() != '\n');

 return 0;
}

You can also use the function system('PAUSE') but I think this is a bit slower and platform dependent

You can take the ToArray() call off the end. Is there a reason you need it to be an array after the call to Concat?

Calling Concat creates an iterator over both arrays. It does not create a new array so you have not used more memory for a new array. When you call ToArray you actually do create a new array and take up the memory for the new array.

So if you just need to easily iterate over both then just call Concat.

The simplest way is to just redirect the output, like so:

Compare-Object $(Get-Content c:\user\documents\List1.txt) $(Get-Content c:\user\documents\List2.txt) > c:\user\documents\diff_output.txt

> will cause the output file to be overwritten if it already exists.
>> will append new text to the end of the output file if it already exists.

StreamReader reader = new StreamReader(Oldfilepath);
string fileContent = reader.ReadToEnd();

StreamWriter writer = new StreamWriter(NewFilePath);
writer.Write(fileContent);

If your template.html file is just HTML and not a React component, then you can't require it in the same way you would do with a JS file.

However, if you are using Browserify — there is a transform called stringify which will allow you to require non-js files as strings. Once you have added the transform, you will be able to require HTML files and they will export as though they were just strings.

Once you have required the HTML file, you'll have to inject the HTML string into your component, using the dangerouslySetInnerHTML prop.

var __html = require('./template.html');
var template = { __html: __html };

React.module.exports = React.createClass({
  render: function() {
    return(
      <div dangerouslySetInnerHTML={template} />
    );
  }
});

This goes against a lot of what React is about though. It would be more natural to create your templates as React components with JSX, rather than as regular HTML files.

The JSX syntax makes it trivially easy to express structured data, like HTML, especially when you use stateless function components.

If your template.html file looked something like this

<div class='foo'>
  <h1>Hello</h1>
  <p>Some paragraph text</p>
  <button>Click</button>
</div>

Then you could convert it instead to a JSX file that looked like this.

module.exports = function(props) {
  return (
    <div className='foo'>
      <h1>Hello</h1>
      <p>Some paragraph text</p>
      <button>Click</button>
    </div>
  );
};

Then you can require and use it without needing stringify.

var Template = require('./template');

module.exports = React.createClass({
  render: function() {
    var bar = 'baz';
    return(
      <Template foo={bar}/>
    );
  }
});

It maintains all of the structure of the original file, but leverages the flexibility of React's props model and allows for compile time syntax checking, unlike a regular HTML file.

The two most usual choices are GTK+, which has documentation links here, and is mostly used with C; or Qt which has documentation here and is more used with C++.

I posted these two as you do not specify an operating system and these two are pretty cross-platform.

The way it's often done is as follows:

• allocate an array of some initial (fairly small) size;
• read into this array, keeping track of how many elements you've read;
• once the array is full, reallocate it, doubling the size and preserving (i.e. copying) the contents;
• repeat until done.

I find that this pattern comes up pretty frequently.

What's interesting about this method is that it allows one to insert N elements into an empty array one-by-one in amortized O(N) time without knowing N in advance.

I found the answer.

the statement On Error Resume Next should be placed on top of what we want to validate.

The toISOString() method returns a string in simplified extended ISO format (ISO 8601), which is always 24 or 27 characters long (YYYY-MM-DDTHH:mm:ss.sssZ or ±YYYYYY-MM-DDTHH:mm:ss.sssZ, respectively). The timezone is always zero UTC offset, as denoted by the suffix "Z".

Source: MDN web docs

The format you need is created with the .toISOString() method. For older browsers (ie8 and under), which don't natively support this method, the shim can be found here:

This will give you the ability to do what you need:

var isoDateString = new Date().toISOString();
console.log(isoDateString);

For Timezone work, moment.js and moment.js timezone are really invaluable tools...especially for navigating timezones between client and server javascript.

You can download the needed packages from here and use pip install "Abc.whl" from the directory where you have downloaded the file.

I installed Node.js on bluehost.com (a shared server) using:

wget <path to download file>
tar -xf <gzip file>
mv <gzip_file_dir> node

This will download the tar file, extract to a directory and then rename that directory to the name 'node' to make it easier to use.

then

./node/bin/npm install jt-js-sample

Returns:
npm WARN engine [email protected]: wanted: {"node":"0.10.x"} (current: {"node":"0.12.4","npm":"2.10.1"})

I can now use the commands:

# ~/node/bin/node -v
v0.12.4

# ~/node/bin/npm -v
2.10.1

For security reasons, I have renamed my node directory to something else.

Try adding the following line at the top of your python script.

# _*_ coding:utf-8 _*_

You can do this in Interface Builder:

1) Control-drag from a frame view (e.g. questionFrame) to main View, in the pop-up select "Equal heights".

2)Then go to size inspector of the frame, click edit "Equal height to Superview" constraint, set the multiplier to 0.7 and hit return.

You'll see that constraint has changed from "Equal height to..." to "Proportional height to...".

psxls gave a great answer but I think my Notepad++ version is slightly different so the $ (dollar sign) capturing did not work.

I have Notepad++ v.5.9.3 and here's how you can accomplish your task:

Search for the pattern: value=\"([0-9]*)\" And replace with: \1 (whatever you want to do around that capturing group)

Ex. Surround with square brackets

[\1] --> will produce value="[4]"

Here's a one-liner to get the filename for a module, suitable for shell aliasing:

echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - 

Set up as an alias:

alias getpmpath="echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - "

To use:

$ getpmpath twisted
/usr/lib64/python2.6/site-packages/twisted/__init__.pyc
$ getpmpath twisted.web
/usr/lib64/python2.6/site-packages/twisted/web/__init__.pyc

In addition to the example given in the Advanced Bash Scripting Guide referenced by Jefromi, these examples show how pipes create subshells:

11656 11656
$ echo $$ | while read line; do echo $line $$ $BASHPID; done

Since Qt 5.5 you can use QTextStream::readLineInto. It behaves similar to std::getline and is maybe faster as QTextStream::readLine, because it reuses the string:

QIODevice* device;
QTextStream in(&device);

QString line;
while (in.readLineInto(&line)) {
  // ...
}

For MVC4, using a Enum (UserRoles) with my roles, I use a custom AuthorizeAttribute.

On my controlled action, I do:

[CustomAuthorize(UserRoles.Admin, UserRoles.User)]
public ActionResult ChangePassword()
{
    return View();
}

And I use a custom AuthorizeAttribute like that:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class CustomAuthorize : AuthorizeAttribute
{
    private string[] UserProfilesRequired { get; set; }

    public CustomAuthorize(params object[] userProfilesRequired)
    {
        if (userProfilesRequired.Any(p => p.GetType().BaseType != typeof(Enum)))
            throw new ArgumentException("userProfilesRequired");

        this.UserProfilesRequired = userProfilesRequired.Select(p => Enum.GetName(p.GetType(), p)).ToArray();
    }

    public override void OnAuthorization(AuthorizationContext context)
    {
        bool authorized = false;

        foreach (var role in this.UserProfilesRequired)
            if (HttpContext.Current.User.IsInRole(role))
            {
                authorized = true;
                break;
            }

        if (!authorized)
        {
            var url = new UrlHelper(context.RequestContext);
            var logonUrl = url.Action("Http", "Error", new { Id = 401, Area = "" });
            context.Result = new RedirectResult(logonUrl);

            return;
        }
    }
}

You may also set {{ant.build.javac.target=1.5}} ant property to update default target version of task. See http://ant.apache.org/manual/javacprops.html#target

If you want the month year unique pair, using apply is pretty sleek.

df['mnth_yr'] = df['date_column'].apply(lambda x: x.strftime('%B-%Y')) 

Outputs month-year in one column.

Don't forget to first change the format to date-time before, I generally forget.

df['date_column'] = pd.to_datetime(df['date_column'])

You can use the ArrayUtils class from commons-lang to obtain a double[] from a Double[].

Double[] ds = frameList.toArray(new Double[frameList.size()]);
...
double[] d = ArrayUtils.toPrimitive(ds);

I just tried the same and came up with following solution:

public enum Countries {
    TEXAS,
    FLORIDA,
    OKLAHOMA,
    KENTUCKY;

    private static Countries[] list = Countries.values();

    public static Countries getCountry(int i) {
        return list[i];
    }

    public static int listGetLastIndex() {
        return list.length - 1;
    }
}

The class has it's own values saved inside an array, and I use the array to get the enum at indexposition. As mentioned above arrays begin to count from 0, if you want your index to start from '1' simply change these two methods to:

public static String getCountry(int i) {
    return list[(i - 1)];
}

public static int listGetLastIndex() {
    return list.length;
}

Inside my Main I get the needed countries-object with

public static void main(String[] args) {
   int i = Countries.listGetLastIndex();
   Countries currCountry = Countries.getCountry(i);
}

which sets currCountry to the last country, in this case Countries.KENTUCKY.

Just remember this code is very affected by ArrayOutOfBoundsExceptions if you're using hardcoded indicies to get your objects.

In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia

In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict) into its valid JSON pendant (object).

• Python's True will be converted to JSONs true and the dictionary itself will then be encapsulated in quotes.
• You can easily spot the difference between a Python dictionary and JSON by their Boolean values:
  • Python: True / False,
  • JSON: true / false
• Python builtin module json is the standard way to do serialization:

Code example:

data = {
    "president": {
        "name": "Zaphod Beeblebrox",
        "species": "Betelgeusian",
        "male": True,
    }
}

import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize

# serialized json_data now looks like:
# {
#   "president": {
#     "name": "Zaphod Beeblebrox",
#     "species": "Betelgeusian",
#     "male": true
#   }
# }

Source: realpython.com

Its been updated so

root.configure(background="red")

is now:

root.configure(bg="red")

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

You can use the container, It will help you to set the alignment.

Widget _buildListWidget({Map reminder}) {
return Container(
  color: Colors.amber,
  alignment: Alignment.centerLeft,
  padding: EdgeInsets.all(20),
  height: 80,
  child: Column(
    mainAxisAlignment: MainAxisAlignment.center,
    crossAxisAlignment: CrossAxisAlignment.center,
    children: <Widget>[
      Container(
        alignment: Alignment.centerLeft,
        child: Text(
          reminder['title'],
          textAlign: TextAlign.left,
          style: TextStyle(
            fontSize: 16,
            color: Colors.black,
            backgroundColor: Colors.blue,
            fontWeight: FontWeight.normal,
          ),
        ),
      ),
      Container(
        alignment: Alignment.centerRight,
        child: Text(
          reminder['Date'],
          textAlign: TextAlign.right,
          style: TextStyle(
            fontSize: 12,
            color: Colors.grey,
            backgroundColor: Colors.blue,
            fontWeight: FontWeight.normal,
          ),
        ),
      ),
    ],
  ),
);
}

I'm assuming this is for a game or for a fast-responding type of application hence the use of KEYDOWN than KEYPRESS.

Edit: Dang! I stand corrected (thank you Crescent Fresh and David): JQuery (or even rather the underlying DOM hosts) do not expose the detail of the WM_KEYDOWN and of other events. Rather they pre-digest this data and, in the case of keyDown even in JQuery, we get:

• event.keyCode for non-character keys
• event.charCode for character keys

Note that these properties are the UniCode values.
Note, I wasn't able to find an authorititative reference to that in JQuery docs, but many reputable examples on the net refer to these two properties.

The following code, adapted from some java (not javascript) of mine, is therefore totally wrong...

The following will give you the "interesting" parts of the keycode:

  value = e.KeyCode;
  repeatCount = value & 0xFF;
  scanCode = (value >> 16) & 0xFF;  // note we take the "extended bit" deal w/ it later.
  wasDown = ((value & 0x4000) != 0);  // indicate key was readily down (auto-repeat)
  if (scanCode > 127)
      // deal with extended
  else
      // "regular" character

You can also use the Runtime to create a cross platform solution:

import java.awt.Desktop;
import java.net.URI;

public class App {

    public static void main(String[] args) throws Exception {
        String url = "http://stackoverflow.com";

        if (Desktop.isDesktopSupported()) {
            // Windows
            Desktop.getDesktop().browse(new URI(url));
        } else {
            // Ubuntu
            Runtime runtime = Runtime.getRuntime();
            runtime.exec("/usr/bin/firefox -new-window " + url);
        }
    }
}

In Swift 3:

NSLocale.current.languageCode

The content inside strings in Golang can be compared using == operator. If the results are not as expected there may be some hidden characters like \n, \r, spaces, etc. So as a general rule of thumb, try removing those using functions provided by strings package in golang.

For Instance, spaces can be removed using strings.TrimSpace function. You can also define a custom function to remove any character you need. strings.TrimFunc function can give you more power.

You can also provide a negative number as an argument to the round method to round to the nearest multiple of 10, 100 and so on.

# Round to the nearest multiple of 10. 
12.3453.round(-1)       # Output: 10

# Round to the nearest multiple of 100. 
124.3453.round(-2)      # Output: 100

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

The following example Web.config file will configure IIS to deny access for HTTP requests where the length of the "Content-type" header is greater than 100 bytes.

  <configuration>
   <system.webServer>
      <security>
         <requestFiltering>
            <requestLimits>
               <headerLimits>
                  <add header="Content-type" sizeLimit="100" />
               </headerLimits>
            </requestLimits>
         </requestFiltering>
      </security>
   </system.webServer>
</configuration>

If performance is an issue, you could use a MySQL variable:

set @csum := 0;
update YourTable
set cumulative_sum = (@csum := @csum + count)
order by id;

Alternatively, you could remove the cumulative_sum column and calculate it on each query:

set @csum := 0;
select id, count, (@csum := @csum + count) as cumulative_sum
from YourTable
order by id;

This calculates the running sum in a running way :)

You must turn debug off for database in config/database.php ->

$db['default']['db_debug'] = FALSE;

It is better for your website security.

I know this is an old thread, but I experienced the same issue with an inline form, and none of the options above solved the issue. So I fixed my inline form like so:-

<form class="form-inline" action="" method="post" accept-charset="UTF-8">
    <div class="row">
        <div class="form-group col-xs-7" style="padding-right: 0;">
            <label class="sr-only" for="term">Search</label>
            <input type="text" class="form-control" style="width: 100% !important;" name="term" id="term" placeholder="Search..." autocomplete="off">
            <span class="help-block">0 results</span>
        </div>
        <div class="form-group col-xs-2">
            <button type="submit" name="search" class="btn btn-success" id="search">Search</button>
        </div>
    </div>
</form>

That was my solution. Bit hacky hack, but did the job for an inline form.

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

  if (window.sidebar) { // Mozilla Firefox Bookmark
     window.sidebar.addPanel(document.title,location.href,"");

It adds the bookmark but in the sidebar.

Check out this issue. I think the bug will be resolved when new template precompilation logic will be implemented. For now I think the best you can do is to wrap your template into <div class="root"> and style this div:

@Component({ ... })
@View({
  template: `
    <div class="root">
      <h2>Hello Angular2!</h2>
      <p>here is your template</p>
    </div>
  `,
  styles: [`
    .root {
      background: blue;
    }
  `],
   ...
})
class SomeComponent {}

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

You were so close! The kill -HUP method wasn't working for me either.

You were calling:

select @@global.max_connections;

All you needed was to set instead of select:

set @@global.max_connections = 400;

See:

I made a variation of Longpoke's minimalistic approach that also ensures the signatures for both callees and callers:

class EventHook(object):
    '''
    A simple implementation of the Observer-Pattern.
    The user can specify an event signature upon inizializazion,
    defined by kwargs in the form of argumentname=class (e.g. id=int).
    The arguments' types are not checked in this implementation though.
    Callables with a fitting signature can be added with += or removed with -=.
    All listeners can be notified by calling the EventHook class with fitting
    arguments.

    >>> event = EventHook(id=int, data=dict)
    >>> event += lambda id, data: print("%d %s" % (id, data))
    >>> event(id=5, data={"foo": "bar"})
    5 {'foo': 'bar'}

    >>> event = EventHook(id=int)
    >>> event += lambda wrong_name: None
    Traceback (most recent call last):
        ...
    ValueError: Listener must have these arguments: (id=int)

    >>> event = EventHook(id=int)
    >>> event += lambda id: None
    >>> event(wrong_name=0)

    def __call__(self, *args, **kwargs):

You can use RequestDispatcher as you usually use it in Servlet:

<%@ page contentType="text/html"%>
<%@ page import = "javax.servlet.RequestDispatcher" %>
<%
     RequestDispatcher rd = request.getRequestDispatcher("/yourServletUrl");
     request.setAttribute("msg","HI Welcome");
     rd.forward(request, response);
%>

Always be aware that don't commit any response before you use forward, as it will lead to IllegalStateException.

Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size.

Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR (x=b OR (x=c)), so it gets very deep with a large number of OR. SQL 7 would hit a SO at about 10k values in the IN, but nowdays stacks are much deeper (because of x64), so it can go pretty deep.

Update

You already found Erland's article on the topic of passing lists/arrays to SQL Server. With SQL 2008 you also have Table Valued Parameters which allow you to pass an entire DataTable as a single table type parameter and join on it.

XML and XPath is another viable solution:

SELECT ...
FROM Table
JOIN (
   SELECT x.value(N'.',N'uniqueidentifier') as guid
   FROM @values.nodes(N'/guids/guid') t(x)) as guids
 ON Table.guid = guids.guid;

for (int i = 0; i < nodeList.getLength(); i++)

change to

for (int i = 0, len = nodeList.getLength(); i < len; i++)

to be more efficient.

The second way of javanna answer may be the best as it tends to use a flatter, predictable memory model.

You can use the Build Class to get the device information.

For example:

String myDeviceModel = android.os.Build.MODEL;

The Catch is Capture all SQL run between two points in time. Like the way SQL Server also does.

There are situations where it is useful to capture the SQL that a particular user is running in the database. Usually you would simply enable session tracing for that user, but there are two potential problems with that approach.

1. The first is that many web based applications maintain a pool of persistent database connections which are shared amongst multiple users.
2. The second is that some applications connect, run some SQL and disconnect very quickly, making it tricky to enable session tracing at all (you could of course use a logon trigger to enable session tracing in this case).

A quick and dirty solution to the problem is to capture all SQL statements that are run between two points in time.

The following procedure will create two tables, each containing a snapshot of the database at a particular point. The tables will then be queried to produce a list of all SQL run during that period.

If possible, you should do this on a quiet development system - otherwise you risk getting way too much data back.

1. Take the first snapshot Run the following sql to create the first snapshot:

   create table sql_exec_before as
   select executions,hash_value
   from v$sqlarea
   /
   

2. Get the user to perform their task within the application.

3. Take the second snapshot.

   create table sql_exec_after as
   select executions, hash_value
   from v$sqlarea
   /
   

4. Check the results Now that you have captured the SQL it is time to query the results.

This first query will list all query hashes that have been executed:

select  aft.hash_value
from sql_exec_after aft
left outer join sql_exec_before bef
  on aft.hash_value  =  bef.hash_value 
where aft.executions > bef.executions
   or bef.executions is null;
/

This one will display the hash and the SQL itself: set pages 999 lines 100 break on hash_value

select  hash_value, sql_text
from    v$sqltext
where   hash_value in (
    select  aft.hash_value
    from sql_exec_after aft
    left outer join sql_exec_before bef
      on aft.hash_value  =  bef.hash_value
    where aft.executions > bef.executions
       or bef.executions is null;
)
order by
    hash_value, piece
/

5. Tidy up Don't forget to remove the snapshot tables once you've finished:

drop table sql_exec_before
/

drop table sql_exec_after
/

Usually I just check if the index is less than the array size

if (index < list.size()) {
    ...
}

If you are also concerned of index being a negative value, use following

if (index >= 0 && index < list.size()) {
    ...
}

You should never use the unidirectional @OneToMany annotation because:

1. It generates inefficient SQL statements
2. It creates an extra table which increases the memory footprint of your DB indexes

Now, in your first example, both sides are owning the association, and this is bad.

While the @JoinColumn would let the @OneToMany side in charge of the association, it's definitely not the best choice. Therefore, always use the mappedBy attribute on the @OneToMany side.

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<APost> aPosts;

    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<BPost> bPosts;
}

public class BPost extends Post {

    @ManyToOne(fetch=FetchType.LAZY)    
    public User user;
}

public class APost extends Post {

     @ManyToOne(fetch=FetchType.LAZY) 
     public User user;
}

You have two options which are quite similar (by the approach and result):

// option 1:
var string_1 : String = "100"
var double_1 : Double = (string_1 as NSString).doubleValue + 99.0

// option 2: 
var string_2 : NSString = "100"
// or:  var string_2 = "100" as NSString
var number_2 : Double = string_2.doubleValue;

Basically, what this error is saying is that if you are going to use the GROUP BY clause, then your result is going to be a relation/table with a row for each group, so in your SELECT statement you can only "select" the column that you are grouping by and use aggregate functions on that column because the other columns will not appear in the resulting table.

if the database is InnoDB you dont need to do joins in deletion. only

DELETE FROM spawnlist WHERE spawnlist.type = "monster";

can be used to delete the all the records that linked with foreign keys in other tables, to do that you have to first linked your tables in design time.

CREATE TABLE IF NOT EXIST spawnlist (
  npc_templateid VARCHAR(20) NOT NULL PRIMARY KEY

)ENGINE=InnoDB;

CREATE TABLE IF NOT EXIST npc (
  idTemplate VARCHAR(20) NOT NULL,

  FOREIGN KEY (idTemplate) REFERENCES spawnlist(npc_templateid) ON DELETE CASCADE

)ENGINE=InnoDB;

if you uses MyISAM you can delete records joining like this

DELETE a,b
FROM `spawnlist` a
JOIN `npc` b
ON a.`npc_templateid` = b.`idTemplate`
WHERE a.`type` = 'monster';

in first line i have initialized the two temp tables for delet the record, in second line i have assigned the existance table to both a and b but here i have linked both tables together with join keyword, and i have matched the primary and foreign key for both tables that make link, in last line i have filtered the record by field to delete.

If you are using Microsoft windows environment then you can set a variable named HTTP_PROXY, FTP_PROXY, or HTTPS_PROXY depending on the requirement.

I have used following settings for allowing my commands at windows command prompt to use the browser proxy to access internet.

set HTTP_PROXY=http://proxy_userid:proxy_password@proxy_ip:proxy_port

The parameters on right must be replaced with actual values.

Once the variable HTTP_PROXY is set, all our subsequent commands executed at windows command prompt will be able to access internet through the proxy along with the authentication provided.

Additionally if you want to use ftp and https as well to use the same proxy then you may like to the following environment variables as well.

set FTP_PROXY=%HTTP_PROXY%

set HTTPS_PROXY=%HTTP_PROXY%

Unfortunately there's a simple answer to this question, and it's "No"

Use this function like

 String.prototype.text=function(){
   return this ? String(this).replace(/<[^>]+>/gm, '') : '';
 }

  "<span>My text</span>".text()
  output:
  My text

Fiddle

Make sure you have created persistence.xml file under the 'src' folder. I created under the project folder and that was my problem.

When you run some function inside setInterval, which works more time than timeout-> the browser will be stuck.

- E.g., doStuff() takes 1500 sec. to be execute and you do: setInterval(doStuff, 1000);
1) Browser run doStuff() which takes 1.5 sec. to be executed;
2) After ~1 second it tries to run doStuff() again. But previous doStuff() is still executed-> so browser adds this run to the queue (to run after first is done).
3,4,..) The same adding to the queue of execution for next iterations, but doStuff() from previous are still in progress...
As the result- the browser is stuck.

To prevent this behavior, the best way is to run setTimeout inside setTimeout to emulate setInterval.
To correct timeouts between setTimeout calls, you can use self-correcting alternative to JavaScript's setInterval technique.

See String.format method.

String s = "hello %s!";
s = String.format(s, "world");
assertEquals(s, "hello world!"); // should be true

You can bind a click handler that returns false:

$('.my-link').click(function () {return false;});

To re-enable it again, unbind the handler:

$('.my-link').unbind('click');

Note that disabled doesn't work because it is designed for form inputs only.

jQuery has anticipated this already, providing a shortcut as of jQuery 1.4.3:

$('.my-link').bind('click', false);

And to unbind / re-enable:

$('.my-link').unbind('click', false);

The only way that i know of is to test for it, you can do a combined if though to make it easy.

If NOT IsDbNull(myItem("sID")) AndAlso myItem("sID") = sId Then
   'Do success
ELSE
   'Failure
End If

I wrote in VB as that is what it looks like you need, even though you mixed languages.

Edit

Cleaned up to use IsDbNull to make it more readable

Why not use index or rindex?

array = %w( a b c d e)
# get FIRST index of element searched
puts array.index('a')
# get LAST index of element searched
puts array.rindex('a')

index: http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-index

rindex: http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-rindex

I would use the insert function, something like:

vector<int> a, b;
//fill with data
b.insert(b.end(), a.begin(), a.end());

ArrayList<ArrayList<String>> listOLists = new ArrayList<ArrayList<String>>();
ArrayList<String> singleList = new ArrayList<String>();
singleList.add("hello");
singleList.add("world");
listOLists.add(singleList);

ArrayList<String> anotherList = new ArrayList<String>();
anotherList.add("this is another list");
listOLists.add(anotherList);

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

More concise than others:

def parseString(string):
    try:
        return int(string)
    except ValueError:
        return string

b = [[parseString(s) for s in clause.split(', ')] for clause in a]

Alternatively if your format is fixed as <string>, <int>, <int>, you can be even more concise:

def parseClause(a,b,c):
    return [a, int(b), int(c)]

b = [parseClause(*clause) for clause in a]

myfunc("string*& val") this itself doesn't make any sense. "string*& val" implies "string val",* and & cancels each other. Finally one can not pas string variable to a function("string val"). Only basic data types can be passed to a function, for other data types need to pass as pointer or reference. You can have either string& val or string* val to a function.

I'm going to throw my hat into the ring here:

I've used the __call hack with mixed degrees of success. The alternative I came up with was to use the Visitor pattern:

1: generate a stdClass or custom class (to enforce type)

2: prime that with the required method and arguments

3: ensure that your SUT has an acceptVisitor method which will execute the method with the arguments specified in the visiting class

4: inject it into the class you wish to test

5: SUT injects the result of operation into the visitor

6: apply your test conditions to the Visitor's result attribute

As far as i experienced zposition is a best way.

self.view.layer.zPosition = 1;

BOOTSTRAP 4

If you do not want to kill a fly with bazooka by use -webkit-appearance:none; which also kills nice sliderinputs btw and presuming you are working with the bootstrap form css selector "form-control" for your input.

This is the solution:

.form-control:focus {
    box-shadow: none!important;
    border-color: #ced4da!important;
}

If you want to keep a tiny small blue outline the leave border-color out.

I'm going to repost (since I'm not cool enough yet to comment) in the correct answer....in case anyone else thought it needed better explaining.

SELECT temp_table_1.name
FROM original_table_1 temp_table_1
LEFT JOIN original_table_2 temp_table_2 ON temp_table_2.name = temp_table_1.name
WHERE temp_table_2.name IS NULL

And I've seen syntax in FROM needing commas between table names in mySQL but in sqlLite it seemed to prefer the space.

The bottom line is when you use bad variable names it leaves questions. My variables should make more sense. And someone should explain why we need a comma or no comma.

You can use the Date property of the DateTime object - eg

DateTime midnight = DateTime.Now.Date;

So your code example becomes

private DateTime _Begin = DateTime.Now.Date;
public DateTime Begin { get { return _Begin; } set { _Begin = value; } }

PS. going back to your original code setting the hours to 12 will give you time of noon for the current day, so instead you could have used 0...

var now = DateTime.Now;
new DateTime(now.Year, now.Month, now.Day, 0, 0, 0);

Code check:

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

LINQ is a "query" language (thats the Q), so modifying data is outside its scope.

That said, your DataGridView is presumably bound to an ItemsSource, perhaps of type ObservableCollection<T> or similar. In that case, just do something like X.ToList().ForEach(yourGridSource.Add) (this might have to be adapted based on the type of source in your grid).

If the list to compare against is large, (ie the manilaListRange range in the example above), it is a smart move to use the match function. It avoids the use of a loop which could slow down the procedure. If you can ensure that the manilaListRange is all upper or lower case then this seems to be the best option to me. It is quick to apply 'UCase' or 'LCase' as you do your match.

If you did not have control over the ManilaListRange then you might have to resort to looping through this range in which case there are many ways to compare 'search', 'Instr', 'replace' etc.

• What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?

I'm not sure at what level you are looking for an answer at, so let's take a little trip. Some of this you may already know.

When you build your project, Xcode invokes clang for Objective-C targets and swift/swiftc for Swift targets. Both of these compilers compile the app to an intermediate representation (IR), one of these IRs is bitcode. From this IR, a program called LLVM takes over and creates the binaries needed for x86 32 and 64 bit modes (for the simulator) and arm6/arm7/arm7s/arm64 (for the device). Normally, all of these different binaries are lumped together in a single file called a fat binary.

The ENABLE_BITCODE option cuts out this final step. It creates a version of the app with an IR bitcode binary. This has a number of nice features, but one giant drawback: it can't run anywhere. In order to get an app with a bitcode binary to run, the bitcode needs to be recompiled (maybe assembled or transcoded… I'm not sure of the correct verb) into an x86 or ARM binary.

When a bitcode app is submitted to the App Store, Apple will do this final step and create the finished binaries.

Right now, bitcode apps are optional, but history has shown Apple turns optional things into requirements (like 64 bit support). This usually takes a few years, so third party developers (like Parse) have time to update.

• can I use the above method without any negative impact and without compromising a future appstore submission?

Yes, you can turn off ENABLE_BITCODE and everything will work just like before. Until Apple makes bitcode apps a requirement for the App Store, you will be fine.

• Are there any performance impacts if I enable / disable it?

There will never be negative performance impacts for enabling it, but internal distribution of an app for testing may get more complicated.

As for positive impacts… well that's complicated.

For distribution in the App Store, Apple will create separate versions of your app for each machine architecture (arm6/arm7/arm7s/arm64) instead of one app with a fat binary. This means the app installed on iOS devices will be smaller.

In addition, when bitcode is recompiled (maybe assembled or transcoded… again, I'm not sure of the correct verb), it is optimized. LLVM is always working on creating new a better optimizations. In theory, the App Store could recreate the separate version of the app in the App Store with each new release of LLVM, so your app could be re-optimized with the latest LLVM technology.

To add to Alan Wells's elaborate answer here is a quick fix

Run a Local Server

you can serve any folder in your computer with Serve

First, navigate using the command line into the folder you'd like to serve.

Then

npx i -g serve
serve

or if you'd like to test Serve without downloading it

npx serve

and that's it! You can view your files at http://localhost:5000

for update: event: React.ChangeEvent for submit: event: React.FormEvent for click: event: React.MouseEvent

Nothing special, just saving the cost it takes to return a value at certain index from an array.

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

compile function -

1. is called before the controller and link function.
2. In compile function, you have the original template DOM so you can make changes on original DOM before AngularJS creates an instance of it and before a scope is created
3. ng-repeat is perfect example - original syntax is template element, the repeated elements in HTML are instances
4. There can be multiple element instances and only one template element
5. Scope is not available yet
6. Compile function can return function and object
7. returning a (post-link) function - is equivalent to registering the linking function via the link property of the config object when the compile function is empty.
8. returning an object with function(s) registered via pre and post properties - allows you to control when a linking function should be called during the linking phase. See info about pre-linking and post-linking functions below.

syntax

function compile(tElement, tAttrs, transclude) { ... }

controller

1. called after the compile function
2. scope is available here
3. can be accessed by other directives (see require attribute)

pre - link

1. The link function is responsible for registering DOM listeners as well as updating the DOM. It is executed after the template has been cloned. This is where most of the directive logic will be put.

2. You can update the dom in the controller using angular.element but this is not recommended as the element is provided in the link function

3. Pre-link function is used to implement logic that runs when angular js has already compiled the child elements but before any of the child element's post link have been called

post-link

1. directive that only has link function, angular treats the function as a post link

2. post will be executed after compile, controller and pre-link funciton, so that's why this is considered the safest and default place to add your directive logic

One of the answers ask you to use buildToolsVersion 23.0.0, but you would get buildToolsVersion 23.0.0 has serious bugs use buildToolsVersion 23.0.3. I did that then I started getting message buildToolsVersion 23.0.3 is too low from project app update to buildToolsVersion 25.0.0 and sync again. So I did that and it worked , So here are the final changes.

Inside app's build.gradle change this

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0 rc2"
}

with this one

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0"
}

Browser development progresses:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString

 Number.toLocaleString(locale);

 // E.g.
 parseFloat("1234567.891").toLocaleString(window.document.documentElement.lang);
 "1,234,567.891"

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

It depends how many rows are returned in $results, and how many columns there are in $row?
