I deleted folders build inside a project. After cleaned and rebuilt it in Android Studio. Then corrected errors in build.gradle and AndroidManifest.

This was a fun question! Another way to handle this for variable length lists is to build a function that takes full advantage of the .format method and list unpacking. In the following example I don't use any fancy formatting, but that can easily be changed to suit your needs.

list_1 = [1,2,3,4,5,6]
list_2 = [1,2,3,4,5,6,7,8]

# Create a function that can apply formatting to lists of any length:
def ListToFormattedString(alist):
    # Create a format spec for each item in the input `alist`.
    # E.g., each item will be right-adjusted, field width=3.
    format_list = ['{:>3}' for item in alist] 

    # Now join the format specs into a single string:
    # E.g., '{:>3}, {:>3}, {:>3}' if the input list has 3 items.
    s = ','.join(format_list)

    # Now unpack the input list `alist` into the format string. Done!
    return s.format(*alist)

# Example output:
>>>ListToFormattedString(list_1)
'  1,  2,  3,  4,  5,  6'
>>>ListToFormattedString(list_2)
'  1,  2,  3,  4,  5,  6,  7,  8'

This problem consists of two very different sub-problems:

• the string must be seemingly random
• the string must be unique

While randomness is quite easily achieved, the uniqueness without a retry loop is not. This brings us to concentrate on the uniqueness first. Non-random uniqueness can trivially be achieved with AUTO_INCREMENT. So using a uniqueness-preserving, pseudo-random transformation would be fine:

• Hash has been suggested by @paul
• AES-encrypt fits also
• But there is a nice one: RAND(N) itself!

A sequence of random numbers created by the same seed is guaranteed to be

• reproducible
• different for the first 8 iterations
• if the seed is an INT32

So we use @AndreyVolk's or @GordonLinoff's approach, but with a seeded RAND:

e.g. Assumin id is an AUTO_INCREMENT column:

INSERT INTO vehicles VALUES (blah); -- leaving out the number plate
SELECT @lid:=LAST_INSERT_ID();
UPDATE vehicles SET numberplate=concat(
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@lid)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed:=round(rand(@seed)*4294967296))*36+1, 1),
  substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', rand(@seed)*36+1, 1)
)
WHERE id=@lid;

Here is a solution using object-scan

// const objectScan = require('object-scan');

const cars = { label: 'Autos', subs: [ { label: 'SUVs', subs: [] }, { label: 'Trucks', subs: [ { label: '2 Wheel Drive', subs: [] }, { label: '4 Wheel Drive', subs: [ { label: 'Ford', subs: [] }, { label: 'Chevrolet', subs: [] } ] } ] }, { label: 'Sedan', subs: [] } ] };

const find = (haystack, label) => objectScan(['**.label'], {
  filterFn: ({ value }) => value === label,
  rtn: 'parent',
  abort: true
})(haystack);

console.log(find(cars, 'Sedan'));
// => { label: 'Sedan', subs: [] }
console.log(find(cars, 'SUVs'));
// => { label: 'SUVs', subs: [] }

PROMPT text to print

Note: must use Run as Script (F5) not Run Statement (Ctl + Enter)

Why not do string suppression with triple quotes:

>>> s = """my string with "some" double quotes"""
>>> print s
my string with "some" double quotes

A lot of this is already available via JMX. With Java 5, JMX is built-in and they include a JMX console viewer with the JDK.

You can use JMX to monitor manually, or invoke JMX commands from Java if you need this information in your own run-time.

Java and HTTPS url connection without downloading certificate

If you really want to avoid downloading the server's certificate, then use an anonymous protocol like Anonymous Diffie-Hellman (ADH). The server's certificate is not sent with ADH and friends.

You select an anonymous protocol with setEnabledCipherSuites. You can see the list of cipher suites available with getEnabledCipherSuites.

Related: that's why you have to call SSL_get_peer_certificate in OpenSSL. You'll get a X509_V_OK with an anonymous protocol, and that's how you check to see if a certificate was used in the exchange.

But as Bruno and Stephed C stated, its a bad idea to avoid the checks or use an anonymous protocol.

Another option is to use TLS-PSK or TLS-SRP. They don't require server certificates either. (But I don't think you can use them).

The rub is, you need to be pre-provisioned in the system because TLS-PSK is Pres-shared Secret and TLS-SRP is Secure Remote Password. The authentication is mutual rather than server only.

In this case, the mutual authentication is provided by a property that both parties know the shared secret and arrive at the same premaster secret; or one (or both) does not and channel setup fails. Each party proves knowledge of the secret is the "mutual" part.

Finally, TLS-PSK or TLS-SRP don't do dumb things, like cough up the user's password like in a web app using HTTP (or over HTTPS). That's why I said each party proves knowledge of the secret...

If you notice, the code actually splits the chars into an array prior to do any permutation, so you simply remove the join and split operation

var permArr = [],_x000D_
  usedChars = [];_x000D_
_x000D_
function permute(input) {_x000D_
  var i, ch;_x000D_
  for (i = 0; i < input.length; i++) {_x000D_
    ch = input.splice(i, 1)[0];_x000D_
    usedChars.push(ch);_x000D_
    if (input.length == 0) {_x000D_
      permArr.push(usedChars.slice());_x000D_
    }_x000D_
    permute(input);_x000D_
    input.splice(i, 0, ch);_x000D_
    usedChars.pop();_x000D_
  }_x000D_
  return permArr_x000D_
};_x000D_
_x000D_
_x000D_
document.write(JSON.stringify(permute([5, 3, 7, 1])));

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

Run your program with valgrind of linked to efence. That will tell you where the pointer is being dereferenced and most likely fix your problem if you fix all the errors they tell you about.

Access requires parentheses in the FROM clause for queries which include more than one join. Try it this way ...

FROM
    ((tbl_employee
    INNER JOIN tbl_netpay
    ON tbl_employee.emp_id = tbl_netpay.emp_id)
    INNER JOIN tbl_gross
    ON tbl_employee.emp_id = tbl_gross.emp_ID)
    INNER JOIN tbl_tax
    ON tbl_employee.emp_id = tbl_tax.emp_ID;

If possible, use the Access query designer to set up your joins. The designer will add parentheses as required to keep the db engine happy.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

You probably need to run the cygwin shell as Administrator. You can right click the shortcut and click run as administrator or go into the properties of the shortcut and check it in the compatability section. Just beware.... root permissions can be dangerous.

Just use:

$output = array_merge($array1, $array2);

That should solve it. Because you use string keys if one key occurs more than one time (like '44' in your example) one key will overwrite proceding ones with the same name. Because in your case they both have the same value anyway it doesn't matter and it will also remove duplicates.

Update: I just realised, that PHP treats the numeric string-keys as numbers (integers) and so will behave like this, what means, that it renumbers the keys too...

A workaround is to recreate the keys.

$output = array_combine($output, $output);

Update 2: I always forget, that there is also an operator (in bold, because this is really what you are looking for! :D)

$output = $array1 + $array2;

All of this can be seen in: http://php.net/manual/en/function.array-merge.php

A condensed code block is as follows:

   new Handler(Looper.getMainLooper()).post(new Runnable() {
       @Override
       public void run() {
           // things to do on the main thread
       }
   });

This does not involve passing down the Activity reference or the Application reference.

Kotlin Equivalent:

    Handler(Looper.getMainLooper()).post(Runnable {
        // things to do on the main thread
    })

I ran into this on a friend's HTML code and in his case, he was missing quotes.

For example:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
<input type="text" name="fname" id="fname" style="width:90;font-size:10>     
<input type="submit" value="submit"/>
</form>

In this example, a missing quote on the input text fname will simply render the submit button un-usable and the form will not submit.

Of course, this is a bad example because I should be using CSS in the first place ;) but anyways, check all your single and double quotes to see that they are closing properly.

Also, if you have any tags like center, move them out of the form.

<form action="formHandler.php" name="yourForm" id="theForm" method="post">  
<center> <-- bad

As strange it may seems, it can have an impact.

As most answers state setdefault or defaultdict would let you set a default value when a key doesn't exist. However, I would like to point out a small caveat with regard to the use cases of setdefault. When the Python interpreter executes setdefaultit will always evaluate the second argument to the function even if the key exists in the dictionary. For example:

In: d = {1:5, 2:6}

In: d
Out: {1: 5, 2: 6}

In: d.setdefault(2, 0)
Out: 6

In: d.setdefault(2, print('test'))
test
Out: 6

As you can see, print was also executed even though 2 already existed in the dictionary. This becomes particularly important if you are planning to use setdefault for example for an optimization like memoization. If you add a recursive function call as the second argument to setdefault, you wouldn't get any performance out of it as Python would always be calling the function recursively.

Since memoization was mentioned, a better alternative is to use functools.lru_cache decorator if you consider enhancing a function with memoization. lru_cache handles the caching requirements for a recursive function better.

As a JavaScript fallback (or your sole solution), you can use my jQuery Scalem plugin, which lets you scale relative to the parent element (container) by passing the reference option.

You can also try with /usr/local/bin/git it worked for me

Previous answer is not correct in my experience, you can't pass it a simple string, needs to be a datetime object. So:

import datetime 
df.loc[datetime.date(year=2014,month=1,day=1):datetime.date(year=2014,month=2,day=1)]

There's also UJMP

If you are asking whether there's shorthand version of operator .. - no there isn't. You cannot write a ..= b. You'll have to type it in full: filename = filename .. ".tmp"

Constructors are not normal methods and they cannot be "overridden". Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass. This isn't true... a subclass doesn't have any constructors by default (except a no-arg constructor if the class it extends has one). It has to explicitly declare any other constructors, and those constructors belong to it and not to its superclass, even if they take the same parameters that the superclass constructors take.

The stuff you mention about default no arg constructors is just an aspect of how constructors work and has nothing to do with overriding.

Have a look at Runtime.exec() Javadoc

Process p = Runtime.getRuntime().exec("ssh myhost");
PrintStream out = new PrintStream(p.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));

out.println("ls -l /home/me");
while (in.ready()) {
  String s = in.readLine();
  System.out.println(s);
}
out.println("exit");

p.waitFor();

I think it's the shortest answer

Edit the code as you like

There is a good post about this: https://itnext.io/protobuf-and-null-support-1908a15311b6

The solution depends on your actual use case:

• Handling partial update

• Support null

It can be done like this:

import numpy as np

# create a random matrix:
A = np.random.normal(size=(5,2))

# add a column of zeros to it:
print(np.hstack((A,np.zeros((A.shape[0],1)))))

In general, if A is an m*n matrix, and you need to add a column, you have to create an n*1 matrix of zeros, then use "hstack" to add the matrix of zeros to the right of the matrix A.

You want to git rebase -i to perform an interactive rebase.

If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.

Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f and anybody sharing your code will have to jump through some hoops to pull your changes.

Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.

Here are implementations from phpjs.org:

• array_values
• array_keys

This is not my code, I'm just pointing you to a useful resource.

For me it worked doing this:

Uninstall the previous version: go to C:\users\username\anaconda3 and run the anaconda-uninstall.exe

Install again anaconda

then run the following commands on the anaconda pompt:

conda create -n my_env python=2.7

conda activate my_env

start the gui app

anaconda-navigator

Use the cmd activity start-activity (or the alternative am start) command, which is a command-line interface to the ActivityManager. Use am to start activities as shown in this help:

$ adb shell am
usage: am [start|instrument]
       am start [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
                [-c <CATEGORY> [-c <CATEGORY>] ...]
                [-e <EXTRA_KEY> <EXTRA_VALUE> [-e <EXTRA_KEY> <EXTRA_VALUE> ...]
                [-n <COMPONENT>] [-D] [<URI>]
       ...

For example, to start the Contacts application, and supposing you know only the package name but not the Activity, you can use

$ pkg=com.google.android.contacts
$ comp=$(adb shell cmd package resolve-activity --brief -c android.intent.category.LAUNCHER $pkg | tail -1)
$ adb shell cmd activity start-activity $comp

or the alternative

$ adb shell am start -n $comp

See also http://www.kandroid.org/online-pdk/guide/instrumentation_testing.html (may be a copy of obsolete url : http://source.android.com/porting/instrumentation_testing.html ) for other details.

To terminate the application you can use

$ adb shell am kill com.google.android.contacts

or the more drastic

$ adb shell am force-stop com.google.android.contacts

Remove that the entry from known_hosts using:

ssh-keygen -R *ip_address_or_hostname*

This will remove the problematic IP or hostname from known_hosts file and try to connect again.

From the man pages:

-R hostname
Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).

Swift 3:

self.btn.sendActions(for: .touchUpInside)

Remove the WebDAV works perfectly for my case:

<modules>
  <remove name="WebDAVModule"/>
</modules>
<handlers>
  <remove name="WebDAV" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" 
       type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

it always better to solve the problem through the web.config instead of going to fix it through the iis or machine.config to grantee it wouldn't happen if the app hosted at another machine

Try making the whole sheet font size smaller. Then zoom and save. Make a practice sheet first because it really screws everything up.

Use the Environment.NewLine property

Browsers and OS's determine the style of the select boxes in most cases, and it's next to impossible to alter them with CSS alone. You'll have to look into replacement methods. The main trick is to apply appearance: none which lets you override some of the styling.

My favourite method is this one:

http://cssdeck.com/item/265/styling-select-box-with-css3

It doesn't replace the OS select menu UI element so all the problems related to doing that are non-existant (not being able to break out of the browser window with a long list being the main one).

Good luck :)

I've stumbled upon this problem while trying to augment my WebAPI controllers with extra actions.

Assume you would have

public IEnumerable<string> Get()
{
    return this.Repository.GetAll();
}

[HttpGet]
public void ReSeed()
{
    // Your custom action here
}

There are now two methods that satisfy the request for /api/controller which triggers the problem described by TS.

I didn't want to add "dummy" parameters to my additional actions so I looked into default actions and came up with:

[ActionName("builtin")]
public IEnumerable<string> Get()
{
    return this.Repository.GetAll();
}

for the first method in combination with the "dual" route binding:

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { action = "builtin", id = RouteParameter.Optional },
    constraints: new { id = @"\d+" });

config.Routes.MapHttpRoute(
    name: "CustomActionApi",
    routeTemplate: "api/{controller}/{action}");

Note that even though there is no "action" parameter in the first route template apparently you can still configure a default action allowing us to separate the routing of the "normal" WebAPI calls and the calls to the extra action.

You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file.

Instead of

move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);

Use

$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);

Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.

Add a single line AddKeysToAgent yes on the top of the .ssh/config file. Ofcourse ssh-agent must be running beforehand. If its not running ( check by prep ssh-agent ) , then simply run it eval $(ssh-agent)

Now, the key is loaded systemwide into the memory and you dont have to type in the passphrase again.

UTF-8 and UCS-2/UTF-16 can be distinguished reasonably easily via a byte order mark at the start of the file. If this exists then it's a pretty good bet that the file is in that encoding - but it's not a dead certainty. You may well also find that the file is in one of those encodings, but doesn't have a byte order mark.

I don't know much about ISO-8859-2, but I wouldn't be surprised if almost every file is a valid text file in that encoding. The best you'll be able to do is check it heuristically. Indeed, the Wikipedia page talking about it would suggest that only byte 0x7f is invalid.

There's no idea of reading a file "as it is" and yet getting text out - a file is a sequence of bytes, so you have to apply a character encoding in order to decode those bytes into characters.

Today I had similar situation. Media query did not work. After a while I found that space after 'and' was missing. Proper media query should look like this:

@media screen and (max-width: 1024px) {}

You didn't specify the language nor which driver you are using. Therefore I'm describing it abstractly.

EDIT: You say "I am concatenating simple and short XML file and I do not use serialization, so I need to explicitly escape XML character by hand".

I would strongly advise you not to do it by hand. Use the XML APIs to do it all for you - read in the original files, merge the two into a single document however you need to (you probably want to use XmlDocument.ImportNode), and then write it out again. You don't want to write your own XML parsers/formatters. Serialization is somewhat irrelevant here.

If you can give us a short but complete example of exactly what you're trying to do, we can probably help you to avoid having to worry about escaping in the first place.

Original answer

It's not entirely clear what you mean, but normally XML APIs do this for you. You set the text in a node, and it will automatically escape anything it needs to. For example:

LINQ to XML example:

using System;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XElement element = new XElement("tag",
                                        "Brackets & stuff <>");

        Console.WriteLine(element);
    }
}

DOM example:

using System;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement element = doc.CreateElement("tag");
        element.InnerText = "Brackets & stuff <>";
        Console.WriteLine(element.OuterXml);
    }
}

Output from both examples:

<tag>Brackets &amp; stuff &lt;&gt;</tag>

That's assuming you want XML escaping, of course. If you're not, please post more details.

            Document doc = builder.parse( new InputSource( new StringReader( xmlStr )) ); 

        } catch (Exception e) {  
            e.printStackTrace();  
        } 
  }

You should use Merge: For example:

MERGE INTO employees e
    USING (SELECT * FROM hr_records WHERE start_date > ADD_MONTHS(SYSDATE, -1)) h
    ON (e.id = h.emp_id)
  WHEN MATCHED THEN
    UPDATE SET e.address = h.address
  WHEN NOT MATCHED THEN
    INSERT (id, address)
    VALUES (h.emp_id, h.address);

or

MERGE INTO employees e
    USING hr_records h
    ON (e.id = h.emp_id)
  WHEN MATCHED THEN
    UPDATE SET e.address = h.address
  WHEN NOT MATCHED THEN
    INSERT (id, address)
    VALUES (h.emp_id, h.address);

The min-height property is not supported by all browsers. If you need your #content to extend it's height on longer pages the height property will cut it short.

It's a bit of a hack but you could add an empty div with a width of 1px and height of e.g. 1000px inside your #content div. That will force the content to be at least 1000px high and still allow longer content to extend the height when needed

No more plugins, jQuery has implemented its own jQuery.isNumeric() added in v1.7.

jQuery.isNumeric( value )

Determines whether its argument is anumber.

Samples results

$.isNumeric( "-10" );     // true
$.isNumeric( 16 );        // true
$.isNumeric( 0xFF );      // true
$.isNumeric( "0xFF" );    // true
$.isNumeric( "8e5" );     // true (exponential notation string)
$.isNumeric( 3.1415 );    // true
$.isNumeric( +10 );       // true
$.isNumeric( 0144 );      // true (octal integer literal)
$.isNumeric( "" );        // false
$.isNumeric({});          // false (empty object)
$.isNumeric( NaN );       // false
$.isNumeric( null );      // false
$.isNumeric( true );      // false
$.isNumeric( Infinity );  // false
$.isNumeric( undefined ); // false

Here is an example of how to tie the isNumeric() in with the event listener

$(document).on('keyup', '.numeric-only', function(event) {
   var v = this.value;
   if($.isNumeric(v) === false) {
        //chop off the last char entered
        this.value = this.value.slice(0,-1);
   }
});

or actually round off the other decimal places?

round(number,1)

or even round strictly down?

here is an easy way to use join.

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

spoiler: possible Server Side Problem

Here is what i've found, my code expected the responce from my server, when the server returned just 200 code, it wasnt enough herefrom json parser thrown the error error unexpected end of input

fetch(url, {
        method: 'POST',
        body: JSON.stringify(json),
        headers: {
          'Content-Type': 'application/json'
        }
      })
        .then(res => res.json()) // here is my code waites the responce from the server
        .then((res) => {
          toastr.success('Created Type is sent successfully');
        })
        .catch(err => {
          console.log('Type send failed', err);
          toastr.warning('Type send failed');
        })

Here is a way to add Parameters to the script if you used

pipeline.Commands.AddScript(Script);

This is with using an HashMap as paramaters the key being the name of the variable in the script and the value is the value of the variable.

pipeline.Commands.AddScript(script));
FillVariables(pipeline, scriptParameter);
Collection<PSObject> results = pipeline.Invoke();

And the fill variable method is:

private static void FillVariables(Pipeline pipeline, Hashtable scriptParameters)
{
  // Add additional variables to PowerShell
  if (scriptParameters != null)
  {
    foreach (DictionaryEntry entry in scriptParameters)
    {
      CommandParameter Param = new CommandParameter(entry.Key as String, entry.Value);
      pipeline.Commands[0].Parameters.Add(Param);
    }
  }
}

this way you can easily add multiple parameters to a script. I've also noticed that if you want to get a value from a variable in you script like so:

Object resultcollection = runspace.SessionStateProxy.GetVariable("results");

//results being the name of the v

you'll have to do it the way I showed because for some reason if you do it the way Kosi2801 suggests the script variables list doesn't get filled with your own variables.

One way to do it is to set the image you want to display as a background in a container (td, div, span etc) and then adjust background-position to get the sprite you want.

In order to determine optimal k-cluster in clustering methods. I usually using Elbow method accompany by Parallel processing to avoid time-comsuming. This code can sample like this:

Elbow method

elbow.k <- function(mydata){
dist.obj <- dist(mydata)
hclust.obj <- hclust(dist.obj)
css.obj <- css.hclust(dist.obj,hclust.obj)
elbow.obj <- elbow.batch(css.obj)
k <- elbow.obj$k
return(k)
}

Running Elbow parallel

no_cores <- detectCores()
    cl<-makeCluster(no_cores)
    clusterEvalQ(cl, library(GMD))
    clusterExport(cl, list("data.clustering", "data.convert", "elbow.k", "clustering.kmeans"))
 start.time <- Sys.time()
 elbow.k.handle(data.clustering))
 k.clusters <- parSapply(cl, 1, function(x) elbow.k(data.clustering))
    end.time <- Sys.time()
    cat('Time to find k using Elbow method is',(end.time - start.time),'seconds with k value:', k.clusters)

It works well.

Replace this:

var cat = $.jqURL.get('category');
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
    $(this).select(); // This is where my problem is
});

With this:

$('#cbCategory').val(cat);

Calling val() on a select list will automatically select the option with that value, if any.

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

As mentioned in other answers, you can use set to list all the environment variables or use

set [environment_variable] to get a specific variable with its value.

set [environment_variable]= can be used to remove a variable from the workspace.

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:

Without storing a new procedure you can use a code block and execute to obtain a table of occurences. You can filter results by schema, table or column name.

For those who wanna use maven2 in Mavericks, type:

brew tap homebrew/versions

brew install maven2

If you have already installed maven3, backup 3 links (mvn, m2.conf, mvnDebug) in /usr/local/bin first:

mkdir bak

mv m* bak/

then reinstall:

brew uninstall maven2(only when conflicted)

brew install maven2

The error is because you are including the script links at two places which will do the override and re-initialization of date-picker

It will work..

You need to use setTimeout and pass it a callback function. The reason you can't use sleep in javascript is because you'd block the entire page from doing anything in the meantime. Not a good plan. Use Javascript's event model and stay happy. Don't fight it!

you can try this too much better

import sys

class Logger(object):
    def __init__(self, filename="Default.log"):
        self.terminal = sys.stdout
        self.log = open(filename, "a")

    def write(self, message):
        self.terminal.write(message)
        self.log.write(message)

sys.stdout = Logger("yourlogfilename.txt")
print "Hello world !" # this is should be saved in yourlogfilename.txt

If you're using Blend, to make it extra easy and not have any trouble getting the correct path for the Source attribute, just drag and drop the image from the Project panel onto the designer.

you can try using this

    System.Web.HttpContext.Current.Server.MapPath(path);

or use HostingEnvironment.MapPath

    System.Web.Hosting.HostingEnvironment.MapPath(path);

Bower maintains a single version of modules, it only tries to help you select the correct/best one for you.

Javascript dependency management : npm vs bower vs volo?

NPM is better for node modules because there is a module system and you're working locally. Bower is good for the browser because currently there is only the global scope, and you want to be very selective about the version you work with.

Try df.mean(axis=0) , axis=0 argument calculates the column wise mean of the dataframe so the result will be axis=1 is row wise mean so you are getting multiple values.

pids=$(pgrep <name>)

will get you the pids of all processes with the given name. To kill them all, use

kill -9 $pids

To refrain from using a variable and directly kill all processes with a given name issue

pkill -9 <name>

In Xcode 3.2 just select the Project entry in the Groups & Files panel, then select the menu item Project -> Rename… Worked for me.

SELECT tbl_names.id, tbl_names.name, tbl_names.section
  FROM tbl_names, tbl_section 
 WHERE tbl_names.id = tbl_section.id

I disagree with the recommendation to create separate CSS files for non-editorial images.

Assuming the images are for UI purposes, it's presentation layer styling, and as mentioned above, if you're doing mobile UI's its definitely a good idea to keep all styling in a single file so it can be cached once.

Most answers I've found are long and require being familiar with other modules or advanced python features, and will be rather confusing to someone unless they're already familiar with everything the answer talks about.

Working code for a simplified approach:

import threading, time, random

class ThreadWithResult(threading.Thread):
    def __init__(self, group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None):
        def function():
            self.result = target(*args, **kwargs)
        super().__init__(group=group, target=function, name=name, daemon=daemon)

def function_to_thread(n):
    count = 0
    while count < 3:
            print(f'still running thread {n}')
            count +=1
            time.sleep(3)
    result = random.random()
    print(f'Return value of thread {n} should be: {result}')
    return result


def main():
    thread1 = ThreadWithResult(target=function_to_thread, args=(1,))
    thread2 = ThreadWithResult(target=function_to_thread, args=(2,))
    thread1.start()
    thread2.start()
    thread1.join()
    thread2.join()
    print(thread1.result)
    print(thread2.result)

main()

Explanation: I wanted to simplify things significantly, so I created a ThreadWithResult class and had it inherit from threading.Thread. The nested function function in __init__ calls the threaded function we want to save the value of, and saves the result of that as the instance attribute self.result after the thread finishes executing.

Creating an instance of this is identical to creating an instance of threading.Thread. Pass in the function you want to run on a new thread to the target argument and any arguments that your function might need to the args argument and any keyword arguments to the kwargs argument.

e.g.

my_thread = ThreadWithResult(target=my_function, args=(arg1, arg2, arg3))

I think this is significantly easier to understand than the vast majority of answers, and this approach requires no extra imports! I included the time and random module to simulate the behavior of a thread, but they're not required to achieve the functionality asked in the original question.

I know I'm answering this looong after the question was asked, but I hope this can help more people in the future!

EDIT: I created the save-thread-result PyPI package to allow you to access the same code above and reuse it across projects (GitHub code is here). The PyPI package fully extends the threading.Thread class, so you can set any attributes you would set on threading.thread on the ThreadWithResult class as well!

The original answer above goes over the main idea behind this subclass, but for more information, see the more detailed explanation (from the module docstring) here.

Quick usage example:

pip3 install -U save-thread-result     # MacOS/Linux
pip  install -U save-thread-result     # Windows

python3     # MacOS/Linux
python      # Windows

from save_thread_result import ThreadWithResult

# As of Release 0.0.3, you can also specify values for
#`group`, `name`, and `daemon` if you want to set those
# values manually.
thread = ThreadWithResult(
    target = my_function,
    args   = (my_function_arg1, my_function_arg2, ...)
    kwargs = (my_function_kwarg1=kwarg1_value, my_function_kwarg2=kwarg2_value, ...)
)

thread.start()
thread.join()
if getattr(thread, 'result', None):
    print(thread.result)
else:
    # thread.result attribute not set - something caused
    # the thread to terminate BEFORE the thread finished
    # executing the function passed in through the
    # `target` argument
    print('ERROR! Something went wrong while executing this thread, and the function you passed in did NOT complete!!')

# seeing help about the class and information about the threading.Thread super class methods and attributes available:

You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else. By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment in order to find the action.

I think that you can consider changing your markup. If I am not wrong, you'd like to put an invisible layer above the document and your invisible markup may be preceding your document image (is this correct?).

Instead, I propose that you put the invisible right after the document image but changing the position to absolute.

Notice that you need a parent element to have position: relative and then you will be able to use this idea. Otherwise your absolute layer will be placed just in the top left corner.

An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is html

Hope this helps. See here for more information about CSS positioning.

You can make use of cut, sort and uniq commands as follows:

cat input_file | cut -f 1 | sort | uniq

gets unique values in field 1, replacing 1 by 2 will give you unique values in field 2.

Avoiding UUOC :)

cut -f 1 input_file | sort | uniq

EDIT:

To count the number of unique occurences you can make use of wc command in the chain as:

cut -f 1 input_file | sort | uniq | wc -l

This will return the first 200 characters of words:

preg_replace('/\s+?(\S+)?$/', '', substr($string, 0, 201));

The following worked for me:

Short answer

Run the following via command line (cmd):

TlbImp.exe cvextern.dll        //where cvextern.dll is your dll you want to fix.

And a valid dll will be created for you.

Longer answer

• Open cmd

• Find TlbImp.exe. Probably located in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin. If you can't find it go to your root folder (C:\ or D:) and run:

  dir tlbimp.exe /s              //this will locate the file.
  

• Run tlbimp.exe and put your dll behind it. Example: If your dll is cvextern.dll. You can run:

  TlbImp.exe cvextern.dll
  

• A new dll has been created in the same folder of tlbimp.exe. You can use that as reference in your project.

I solved this issue by doing this:

instead of

<Route path="/" component={HomePage} />

do this

<Route
 path="/" component={props => <HomePage {...props} />} />

If the following conditions are true, then rewrite the URL:
If the requested filename is not a directory,

RewriteCond %{REQUEST_FILENAME} !-d

and if the requested filename is not a regular file that exists,

RewriteCond %{REQUEST_FILENAME} !-f

and if the requested filename is not a symbolic link,

RewriteCond %{REQUEST_FILENAME} !-l

then rewrite the URL in the following way:
Take the whole request filename and provide it as the value of a "url" query parameter to index.php. Append any query string from the original URL as further query parameters (QSA), and stop processing this .htaccess file (L).

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

Apache docs #flag_qsa

Another Example:

RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]

With the [QSA] flag, a request for

/pages/123?one=two

will be mapped to

/page.php?page=123&one=two

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

Yes. Internally it is implemented as open hashing based on a primitive polynomial over Z/2 (source).

Other possibility would be place the html in a non overflow:hidden element placed 'out' of screen, like a position absolute top and left lesse then 5000px, then read this elements height. Its ugly, but work well.

Another option I wanted to mention, you could convert your data into XML and then use jQuery.find(":id='A'") the way you wanted.

There are jQuery plugins to that effect, like json2xml.

Probably not worth the conversion overhead, but that's a one time cost for static data, so it might be useful.

The code you posted is wrong, it should throw an Exception if is catching a specific exception in order to handler IOException but throwing not catched exceptions.

Something like:

public void method() throws Exception{
   try{
           BufferedReader br = new BufferedReader(new FileReader("file.txt"));
   }catch(IOException e){
           System.out.println(e.getMessage());
   }
}

or

public void method(){
   try{
           BufferedReader br = new BufferedReader(new FileReader("file.txt"));
   }catch(IOException e){
           System.out.println("Catching IOException");
           System.out.println(e.getMessage());
   }catch(Exception e){
           System.out.println("Catching any other Exceptions like NullPontException, FileNotFoundExceptioon, etc.");
           System.out.println(e.getMessage());
   }

}

I have the same problem. Finally found the solution:

The Relocate XAMPP option in the setup tool didn't correctly relocate the paths and corrupted them, but I've manually change the directories inside my.ini (base dir, data dir , ...). After that mysql started successfully.

I have written an add-in for SSMS and this problem is fixed there. You can use one of 2 ways:

you can use "Copy current cell 1:1" to copy original cell data to clipboard:

http://www.ssmsboost.com/Features/ssms-add-in-copy-results-grid-cell-contents-line-with-breaks

Or, alternatively, you can open cell contents in external text editor (notepad++ or notepad) using "Cell visualizers" feature: http://www.ssmsboost.com/Features/ssms-add-in-results-grid-visualizers

(feature allows to open contents of field in any external application, so if you know that it is text - you use text editor to open it. If contents is binary data with picture - you select view as picture. Sample below shows opening a picture):

If you just want to display it when you get a response add this to your loadpage()

function loadpage(page_request, containerid){
   if (page_request.readyState == 4 && page_request.status==200) { 
      var container = document.getElementById(containerid);
      container.innerHTML=page_request.responseText;
      container.style.visibility = 'visible';
      // or 
      container.style.display = 'block';
}

but this depend entirely on how you hid the div in the first place

There's no problem with what you've done, but you must remember the difference between function declarations and function expressions.

A function declaration, that is:

function doSomething () {}

Is hoisted entirely to the top of the scope (and like let and const they are block scoped as well).

This means that the following will work:

doSomething() // works!
function doSomething() {}

A function expression, that is:

[const | let | var] = function () {} (or () =>

Is the creation of an anonymous function (function () {}) and the creation of a variable, and then the assignment of that anonymous function to that variable.

So the usual rules around variable hoisting within a scope -- block-scoped variables (let and const) do not hoist as undefined to the top of their block scope.

This means:

if (true) {
    doSomething() // will fail
    const doSomething = function () {}
}

Will fail since doSomething is not defined. (It will throw a ReferenceError)

If you switch to using var you get your hoisting of the variable, but it will be initialized to undefined so that block of code above will still not work. (This will throw a TypeError since doSomething is not a function at the time you call it)

As far as standard practices go, you should always use the proper tool for the job.

Axel Rauschmayer has a great post on scope and hoisting including es6 semantics: Variables and Scoping in ES6

The easiest solution I have found is this one :

<a href="#" ng-click="do(); $event.preventDefault()">Click</a>

$diff = strtotime('2019-11-25') - strtotime('2019-11-10');
echo abs(round($diff / 86400));

for a single line implementation, you can use a lambda expression in a map

map(lambda x:MyModel.objects.get_or_create(name=x), items)

Here, lambda matches each item in items list to x and create a Database record if necessary.

Solution for those, who have problem after moving to KitKat:

"This will get the file path from the MediaProvider, DownloadsProvider, and ExternalStorageProvider, while falling back to the unofficial ContentProvider method" https://stackoverflow.com/a/20559175/690777

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

Here's how to enumerate an object's properties:

var params = { name: 'myname', age: 'myage' }

for (var key in params) {
  alert(key + "=" + params[key]);
}

Okay, it took me a while to see this, but there's no way this compiles:

return String.(ConfigurationManager.AppSettings[paramName]);

You're not even calling a method on the String type. Just do this:

return ConfigurationManager.AppSettings[paramName];

The AppSettings KeyValuePair already returns a string. If the name doesn't exist, it will return null.

Based on your edit you have not yet added a Reference to the System.Configuration assembly for the project you're working in.

Another scenario that can cause this exception is with DataBinding, that is when you use something like this in your layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="point.to.your.model"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@{model.someIntegerVariable}"/>

</layout>

Notice that the variable I'm using is an Integer and I'm assigning it to the text field of the TextView. Since the TextView already has a method with signature of setText(int) it will use this method instead of using the setText(String) and cast the value. Thus the TextView thinks of your input number as a resource value which obviously is not valid.

Solution is to cast your int value to string like this

android:text="@{String.valueOf(model.someIntegerVariable)}"

This feature helps not only delaying expensive calculations, but is also useful to construct mutual dependent or cyclic structures. E.g. this leads to an stack overflow:

trait Foo { val foo: Foo }
case class Fee extends Foo { val foo = Faa() }
case class Faa extends Foo { val foo = Fee() }

println(Fee().foo)
//StackOverflowException

But with lazy vals it works fine

trait Foo { val foo: Foo }
case class Fee extends Foo { lazy val foo = Faa() }
case class Faa extends Foo { lazy val foo = Fee() }

println(Fee().foo)
//Faa()

I was working with talend V7.3.1 and I had poi version "4.1.0" and including xml-beans from the list of dependencies didnt fix my problem (i.e: 2.3.0 and 2.6.0).

It was fixed by downloading the jar "xmlbeans-3.0.1.jar" and adding it to the project

1. The reason this is failing is because (Python 3) input returns a string. To convert it to an integer, use int(some_string).

2. You do not typically keep track of indices manually in Python. A better way to implement such a function would be

   def cat_n_times(s, n):
       for i in range(n):
           print(s) 
   
   text = input("What would you like the computer to repeat back to you: ")
   num = int(input("How many times: ")) # Convert to an int immediately.
   
   cat_n_times(text, num)
   

3. I changed your API above a bit. It seems to me that n should be the number of times and s should be the string.

How about this solution:

str="Hello World" (as stated in problem) srr = str+ ""

open ui.all.css

at the end put

@import "ui.base.css";
@import "ui.theme.css";

div.ui-datepicker {
font-size: 62.5%; 
}

and go !

You should be able to break to a label, like so:

function foo ()
{
    dance:
    for(var k = 0; k < 4; k++){
        for(var m = 0; m < 4; m++){
            if(m == 2){
                break dance;
            }
        }
    }
}

After Uri.TryCreate you can check Uri.Scheme to see if it HTTP(s).

Try this one:

<button class="button" onclick="$('#target').toggle();">
    Show/Hide
</button>
<div id="target" style="display: none">
    Hide show.....
</div>

Another option is to create an extra wrapper to center the element vertically.

#container{_x000D_
  border:solid 1px #33aaff;_x000D_
  width:200px;_x000D_
  height:200px;_x000D_

}

<div id="container">_x000D_

    <div id="centered"></div>_x000D_

From Excel Macro Security - www.excelfunctions.net:

Macro Security in Excel 2007, 2010 & 2013:

.....

The different Excel file types provided by the latest versions of Excel make it clear when workbook contains macros, so this in itself is a useful security measure. However, Excel also has optional macro security settings, which are controlled via the options menu. These are :

'Disable all macros without notification'

• This setting does not allow any macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Disable all macros with notification'

• This setting prevents macros from running. However, if there are macros in a workbook, a pop-up is displayed, to warn you that the macros exist and have been disabled.

'Disable all macros except digitally signed macros'

• This setting only allow macros from trusted sources to run. All other macros do not run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Enable all macros'

• This setting allows all macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros and may not be aware of macros running while you have the file open.

If you trust the macros and are ok with enabling them, select this option:

'Enable all macros'

and this dialog box should not show up for macros.

As for the dialog for saving, after noting that this was running on Excel for Mac 2011, I came across the following question on SO, StackOverflow - Suppress dialog when using VBA to save a macro containing Excel file (.xlsm) as a non macro containing file (.xlsx). From it, removing the dialog does not seem to be possible, except for possibly by some Keyboard Input simulation. I would post another question to inquire about that. Sorry I could only get you halfway. The other option would be to use a Windows computer with Microsoft Excel, though I'm not sure if that is a option for you in this case.

I have same issue , i solved issue :

step-1 : download docker-compose using following command.

     1.  sudo su

     2. sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

Step-2 : Run command

    chmod +x /usr/local/bin/docker-compose

Step-3 : Check docker-compose version

     docker-compose --version

You are missing table NewScores, so it can't be found. Just join this table.

If you really want to avoid joining it directly you can replace NewScores.NetScore with SELECT NetScore FROM NewScores WHERE {conditions on which they should be matched}

You could drop the primary key column and re-create it. All the ids should then be reassigned in order.

However this is probably a bad idea in most situations. If you have other tables that have foreign keys to this table then it will definitely not work.

TASKLIST does not set errorlevel.

echo off
tasklist /fi "imagename eq notepad.exe" |find ":" > nul
if errorlevel 1 taskkill /f /im "notepad.exe"
exit

should do the job, since ":" should appear in TASKLIST output only if the task is NOT found, hence FIND will set the errorlevel to 0 for not found and 1 for found

Nevertheless,

taskkill /f /im "notepad.exe"

will kill a notepad task if it exists - it can do nothing if no notepad task exists, so you don't really need to test - unless there's something else you want to do...like perhaps

echo off
tasklist /fi "imagename eq notepad.exe" |find ":" > nul
if errorlevel 1 taskkill /f /im "notepad.exe"&exit

which would appear to do as you ask - kill the notepad process if it exists, then exit - otherwise continue with the batch

The following command does this automatically for you: This will also delete all the data in the table. So be careful.

TRUNCATE TABLE someTable RESTART IDENTITY;

you could do:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.image as mpimg

def rgb_to_gray(img):
        grayImage = np.zeros(img.shape)
        R = np.array(img[:, :, 0])
        G = np.array(img[:, :, 1])
        B = np.array(img[:, :, 2])

        R = (R *.299)
        G = (G *.587)
        B = (B *.114)

        Avg = (R+G+B)
        grayImage = img

        for i in range(3):
           grayImage[:,:,i] = Avg

        return grayImage       

image = mpimg.imread("your_image.png")   
grayImage = rgb_to_gray(image)  
plt.imshow(grayImage)
plt.show()

I had the same problem while installing Brotli

ERROR

Failed building wheel for Brotli

I solved it by downloading the .whl file from here and installing it using the below command

C:\Users\{user_name}\Downloads>pip install Brotli-1.0.9-cp39-cp39-win_amd64.whl

I'm using flow with vscode but had the same problem. I solved it with these steps:

1. Install the extension Flow Language Support

2. Disable the built-in TypeScript extension:

   1. Go to Extensions tab
   2. Search for @builtin TypeScript and JavaScript Language Features
   3. Click on Disable

I prefer

I believe that Notepad++ has this feature.

Edit (for newer versions)
Install the "XML Tools" plugin (Menu Plugins, Plugin Manager)
Then run: Menu Plugins, Xml Tools, Pretty Print (XML only - with line breaks)

Original answer (for older versions of Notepad++)

Notepad++ menu: TextFX -> HTML Tidy -> Tidy: Reindent XML

This feature however wraps XMLs and that makes it look 'unclean'. To have no wrap,

• open C:\Program Files\Notepad++\plugins\Config\tidy\TIDYCFG.INI,
• find the entry [Tidy: Reindent XML] and add wrap:0 so that it looks like this:

[Tidy: Reindent XML] 
input-xml: yes 
indent:yes 
wrap:0 

You could use RegEx:

Regex.IsMatch(hello, @"^[a-zA-Z]+$");

If you don't like that, you can use LINQ:

hello.All(Char.IsLetter);

Or, you can loop through the characters, and use isAlpha:

Char.IsLetter(character);

Alex' comment looks good but I was still confused with using range. The following worked for me while working on a for condition using length within range.

{% for i in range(0,(nums['list_users_response']['list_users_result']['users'])| length) %}
<li>    {{ nums['list_users_response']['list_users_result']['users'][i]['user_name'] }} </li>
{% endfor %}

To get it so that it can be loaded sensibly by Excel, you need to use a comma (the csv default) as the delimiter, unless you are in a locale (e.g. Europe) where you need a semicolon.

Im using the code below..

DATEPART(WK,@DATE_INSERT) - DATEPART(WK,DATEADD(DAY,1,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@DATE_INSERT),0)))) + 1

A solution with reduce():

int[] array = {23, 3, 56, 97, 42};
// directly print out
Arrays.stream(array).reduce((x, y) -> x > y ? x : y).ifPresent(System.out::println);

// get the result as an int
int res = Arrays.stream(array).reduce((x, y) -> x > y ? x : y).getAsInt();
System.out.println(res);
>>
97
97

In the code above, reduce() returns data in Optional format, which you can convert to int by getAsInt().

If we want to compare the max value with a certain number, we can set a start value in reduce():

int[] array = {23, 3, 56, 97, 42};
// e.g., compare with 100
int max = Arrays.stream(array).reduce(100, (x, y) -> x > y ? x : y);
System.out.println(max);
>>
100

In the code above, when reduce() with an identity (start value) as the first parameter, it returns data in the same format with the identity. With this property, we can apply this solution to other arrays:

double[] array = {23.1, 3, 56.6, 97, 42};
double max = Arrays.stream(array).reduce(array[0], (x, y) -> x > y ? x : y);
System.out.println(max);
>>
97.0

There used to be a statement in the SQLite documentation that the practical size limit of a database file was a few dozen GB:s. That was mostly due to the need for SQLite to "allocate a bitmap of dirty pages" whenever you started a transaction. Thus 256 byte of RAM were required for each MB in the database. Inserting into a 50 GB DB-file would require a hefty (2^8)*(2^10)=2^18=256 MB of RAM.

But as of recent versions of SQLite, this is no longer needed. Read more here.

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

Open the httpd.conf file and search for

"rewrite"

, then remove

"#"

at the starting of the line,so the line looks like.

LoadModule rewrite_module modules/mod_rewrite.so

then restart the wamp.

You cannot use || operators in between 2 case. But you can use multiple case values without using a break between them. The program will then jump to the respective case and then it will look for code to execute until it finds a "break". As a result these cases will share the same code.

switch(value) 
{ 
    case 0: 
    case 1: 
        // do stuff for if case 0 || case 1 
        break; 
    // other cases 
    default: 
        break; 
}

You'll want to use the static method Character.toString(char c) to convert the character into a string first. Then you can use the normal string concatenation functions.

mysqli is provided by php-mysql-5.3.3-40.el6_6.x86_64

You may need to try the following

yum install php-mysql-5.3.3-40.el6_6.x86_64

Collections by themselves do not have a predefined order, therefore you must convert them to a java.util.List. Then you can use one form of java.util.Collections.sort

Collection< T > collection = ...;

List< T > list = new ArrayList< T >( collection );

Collections.sort( list );
 // or
Collections.sort( list, new Comparator< T >( ){...} );

// list now is sorted

Array notaion is the best way of combining styles in react native.

This shows how to combine 2 Style objects,

<Text style={[styles.base, styles.background]} >Test </Text>

this shows how to combine Style object and property,

<Text style={[styles.base, {color: 'red'}]} >Test </Text>

This will work on any react native application.

Try the code below:

$ python
>>> class Container(object):
...     pass 
...
>>> x = Container()
>>> x.a = 10
>>> x.b = 20
>>> x.banana = 100
>>> x.a, x.b, x.banana
(10, 20, 100)
>>> dir(x)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', 
'__getattribute__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__',     '__sizeof__', 
'__str__', '__subclasshook__', '__weakref__', 'a', 'b', 'banana']

In addition to the solution you accepted, you could also implement the special __lt__() ("less than") method on the class. The sort() method (and the sorted() function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.

class Foo(object):

     def __init__(self, score):
         self.score = score

     def __lt__(self, other):
         return self.score < other.score

l = [Foo(3), Foo(1), Foo(2)]
l.sort()

I found that a combination of the other answers works:

interface ApiInterface {
    @GET("/someurl")
    Call<ResponseBody> getdata()
}

apiService.getdata().enqueue(object : Callback {
    override fun onResponse(call: Call, response: Response) {
        val rawJsonString = response.body()?.string()
    }
})

The important part are that the response type should be ResponseBody and use response.body()?.string() to get the raw string.

Another Solution to isolate a character in a string

package main
import "fmt"

   func main() {
        var word string = "ZbjTS"

       // P R I N T 
       fmt.Println(word)
       yo := string([]rune(word)[0])
       fmt.Println(yo)

       //I N D E X 
       x :=0
       for x < len(word){
           yo := string([]rune(word)[x])
           fmt.Println(yo)
           x+=1
       }

}

for string arrays also:

fmt.Println(string([]rune(sArray[0])[0]))

// = commented line

Install mysysgit. (Same as Greg Hewgill's answer.)

Install Tortoisegit. (Tortoisegit requires mysysgit or something similiar like Cygwin.)

After TortoiseGit is installed, right-click on a folder, select Git Clone..., then enter the Url of the repository, then click Ok.

This answer is not any better than just installing mysysgit, but you can avoid the dreaded command line. :)

Just use;

$('#selectedDueDate').val(dateText).trigger('input');

Just run the main method which is in the class SampleWebJspApplication. Spring Boot will take care of all the rest (starting the embedded tomcat which will host your sample application).

string input = "OneTwoThree";
(if input.length >5)
{
string str=input.substring(input.length-5,5);
}

        t2=new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.print(mycount++ + " even \n");
                try {

                }
                if(mycount>25)
                    System.exit(0);
                run();
            }
        });
        t=new Thread(new Runnable() {
            @Override

                System.out.print(mycount++ + " odd \n");
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {

                }
                if(mycount>26)
                    System.exit(0);
                run();

First check if you have configured JDK correctly:

• Go to File->Project Structure -> SDKs
• your JDK home path should be something like this: /Library/Java/JavaVirtualMachine/jdk.1.7.0_79.jdk/Contents/Home
• Hit Apply and then OK

Secondly check if you have provided in path in Library's section

• Go to File->Project Structure -> Libraries
• Hit the + button
• Add the path to your src folder
• Hit Apply and then OK

This should fix the problem

Since version 1.7 ansible has the run_once option. Section also contains some discussion of various other techniques.

Simple and Nice. You don't have to change your views. Bjax handles all your links. Check this out: Bjax

Usage:

<script src="bjax.min.js" type="text/javascript"></script>
<link href="bjax.min.css" rel="stylesheet" type="text/css" />

Finally, include this in the HEAD of your html:

$('a').bjax();

I encountered this error working in Talend. I was able to store S3 CSV files created from Redshift without a problem. The error occurred when I was trying to load the same S3 CSV files into an Amazon RDS MySQL database. I tried the default timestamp Talend timestamp formats but they were throwing exception:unparseable date when loading into MySQL.

This from the accepted answer helped me solve this problem:

By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse(). This means that the inputDate isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z". You'll probably need to modify the pattern to match the inputDate's actual pattern

The key to my solution was changing the Talend schema. Talend set the timestamp field to "date" so I changed it to "timestamp" then I inserted "yyyy-MM-dd HH:mm:ss z" into the format string column view a screenshot here talend schema

I had other issues with 12 hour and 24 hour timestamp translations until I added the "z" at the end of the timestamp string.

Use an overloaded method without the out parameter to call the one with the out parameter for C# 6.0 and lower. I'm not sure why a C# 7.0 for .NET Core is even the correct answer for this thread when it was specifically asked if C# 4.0 can have an optional out parameter. The answer is NO!

I had yet another issue with the same error!

Turns out I had created a property on a model, but was stupidly calling that property with parentheses.

Hope this helps someone!

I prefer a mutex solution similar to the following. As this way it re-focuses on the app if it is already loaded

using System.Threading;

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetForegroundWindow(IntPtr hWnd);

/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
   bool createdNew = true;
   using (Mutex mutex = new Mutex(true, "MyApplicationName", out createdNew))
   {
      if (createdNew)
      {
         Application.EnableVisualStyles();
         Application.SetCompatibleTextRenderingDefault(false);
         Application.Run(new MainForm());
      }
      else
      {
         Process current = Process.GetCurrentProcess();
         foreach (Process process in Process.GetProcessesByName(current.ProcessName))
         {
            if (process.Id != current.Id)
            {
               SetForegroundWindow(process.MainWindowHandle);
               break;
            }
         }
      }
   }
}

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

For me -D_GLIBCXX_USE_CXX11_ABI=0 didn't help.

It works after I linked to C++ libs version instead of gnustl.

This solution also avoids hasOwnProperty() as Object.keys returns an array of a given object's own enumerable properties.

Object.keys(obj).forEach(function (key) {
 if(typeof obj[key] === 'undefined'){
    delete obj[key];
  }
});

and you can add this as null or '' for stricter cleaning.

No longer works for spreadsheets Protected with Excel 2013 or later -- they improved the pw hash. So now need to unzip .xlsx and hack the internals.

It is a little tricky. First you can use keytool to put the private key into PKCS12 format, which is more portable/compatible than Java's various keystore formats. Here is an example taking a private key with alias 'mykey' in a Java keystore and copying it into a PKCS12 file named myp12file.p12. [note that on most screens this command extends beyond the right side of the box: you need to scroll right to see it all]

keytool -v -importkeystore -srckeystore .keystore -srcalias mykey -destkeystore myp12file.p12 -deststoretype PKCS12
Enter destination keystore password:  
Re-enter new password: 
Enter source keystore password:  
[Storing myp12file.p12]

Now the file myp12file.p12 contains the private key in PKCS12 format which may be used directly by many software packages or further processed using the openssl pkcs12 command. For example,

openssl pkcs12 -in myp12file.p12 -nocerts -nodes
Enter Import Password:
MAC verified OK
Bag Attributes
    friendlyName: mykey
    localKeyID: 54 69 6D 65 20 31 32 37 31 32 37 38 35 37 36 32 35 37 
Key Attributes: <No Attributes>
-----BEGIN RSA PRIVATE KEY-----
MIIC...
.
.
.
-----END RSA PRIVATE KEY-----

Prints out the private key unencrypted.

Note that this is a private key, and you are responsible for appreciating the security implications of removing it from your Java keystore and moving it around.

I ran into an issue with floats and decimals using the implementation selected as the answer above.

This test fails (floats; hash is the same even though I switched 2 values to be negative):

        var obj1 = new { A = 100m, B = 100m, C = 100m, D = 100m};
        var obj2 = new { A = 100m, B = 100m, C = -100m, D = -100m};
        var hash1 = ComputeHash(obj1.A, obj1.B, obj1.C, obj1.D);
        var hash2 = ComputeHash(obj2.A, obj2.B, obj2.C, obj2.D);
        Assert.IsFalse(hash1 == hash2, string.Format("Hashcode values should be different   hash1:{0}  hash2:{1}",hash1,hash2));

But this test passes (with ints):

        var obj1 = new { A = 100m, B = 100m, C = 100, D = 100};
        var obj2 = new { A = 100m, B = 100m, C = -100, D = -100};
        var hash1 = ComputeHash(obj1.A, obj1.B, obj1.C, obj1.D);
        var hash2 = ComputeHash(obj2.A, obj2.B, obj2.C, obj2.D);
        Assert.IsFalse(hash1 == hash2, string.Format("Hashcode values should be different   hash1:{0}  hash2:{1}",hash1,hash2));

I changed my implementation to not use GetHashCode for the primitive types and it seems to work better

    private static int InternalComputeHash(params object[] obj)
    {
        unchecked
        {
            var result = (int)SEED_VALUE_PRIME;
            for (uint i = 0; i < obj.Length; i++)
            {
                var currval = result;
                var nextval = DetermineNextValue(obj[i]);
                result = (result * MULTIPLIER_VALUE_PRIME) + nextval;

            }
            return result;
        }
    }



    private static int DetermineNextValue(object value)
    {
        unchecked
        {

                int hashCode;
                if (value is short
                    || value is int
                    || value is byte
                    || value is sbyte
                    || value is uint
                    || value is ushort
                    || value is ulong
                    || value is long
                    || value is float
                    || value is double
                    || value is decimal)
                {
                    return Convert.ToInt32(value);
                }
                else
                {
                    return value != null ? value.GetHashCode() : 0;
                }
        }
    }

Shortest Code

[x for _,x in sorted(zip(Y,X))]

Example:

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,    0,   1,   2,   2,   0,   1]

Z = [x for _,x in sorted(zip(Y,X))]
print(Z)  # ["a", "d", "h", "b", "c", "e", "i", "f", "g"]

Generally Speaking

[x for _, x in sorted(zip(Y,X), key=lambda pair: pair[0])]

Explained:

1. zip the two lists.
2. create a new, sorted list based on the zip using sorted().
3. using a list comprehension extract the first elements of each pair from the sorted, zipped list.

For more information on how to set\use the key parameter as well as the sorted function in general, take a look at this.

HTML in line styling example:

<td style='text-align:center; vertical-align:middle'></td> 

CSS file example:

td {
    text-align: center;
    vertical-align: middle;
}

With the help of Vonc's answer above I created the following bash script named check.sh:

#!/bin/bash
image_and_tag="$1"
image_and_tag_array=(${image_and_tag//:/ })
if [[ "$(docker images ${image_and_tag_array[0]} | grep ${image_and_tag_array[1]} 2> /dev/null)" != "" ]]; then
  echo "exists"
else
  echo "doesn't exist"
fi

Using it for an existing image and tag will print exists, for example:

./check.sh rabbitmq:3.4.4

Using it for a non-existing image and tag will print doesn't exist, for example:

./check.sh rabbitmq:3.4.3

Because some database can throw an exception at dbContextTransaction.Commit() so better this:

using (var context = new BloggingContext()) 
{ 
  using (var dbContextTransaction = context.Database.BeginTransaction()) 
  { 
    try 
    { 
      context.Database.ExecuteSqlCommand( 
          @"UPDATE Blogs SET Rating = 5" + 
              " WHERE Name LIKE '%Entity Framework%'" 
          ); 

      var query = context.Posts.Where(p => p.Blog.Rating >= 5); 
      foreach (var post in query) 
      { 
          post.Title += "[Cool Blog]"; 
      } 

      context.SaveChanges(false); 

      dbContextTransaction.Commit(); 

      context.AcceptAllChanges();
    } 
    catch (Exception) 
    { 
      dbContextTransaction.Rollback(); 
    } 
  } 
} 

I'm saying the same thing as the other guys, so everyone's correct, I'm just trying to make it more clear.

@@IDENTITY returns the id of the last thing that was inserted by your client's connection to the database.
Most of the time this works fine, but sometimes a trigger will go and insert a new row that you don't know about, and you'll get the ID from this new row, instead of the one you want

SCOPE_IDENTITY() solves this problem. It returns the id of the last thing that you inserted in the SQL code you sent to the database. If triggers go and create extra rows, they won't cause the wrong value to get returned. Hooray

IDENT_CURRENT returns the last ID that was inserted by anyone. If some other app happens to insert another row at an unforunate time, you'll get the ID of that row instead of your one.

If you want to play it safe, always use SCOPE_IDENTITY(). If you stick with @@IDENTITY and someone decides to add a trigger later on, all your code will break.

Try

$('li.current_sub').prev('.par_cat').[do stuff];

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

Slicing works (and is the preferred approach), but just an alternative if more operations are needed (but then converting to a list wouldn't hurt anyway):

>>> a = '123456789'
>>> b = bytearray(a)
>>> del b[3]
>>> b
bytearray(b'12356789')
>>> str(b)
'12356789'

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.

I had same issue reported here. I solved the issue moving the mainTest.cpp from a subfolder src/mainTest/ to the main folder src/ I guess this was your problem too.

myList.GroupBy(test => test.id)
      .Select(grp => grp.First());

Edit: as getting this IEnumerable<> into a List<> seems to be a mystery to many people, you can simply write:

var result = myList.GroupBy(test => test.id)
                   .Select(grp => grp.First())
                   .ToList();

But one is often better off working with the IEnumerable rather than IList as the Linq above is lazily evaluated: it doesn't actually do all of the work until the enumerable is iterated. When you call ToList it actually walks the entire enumerable forcing all of the work to be done up front. (And may take a little while if your enumerable is infinitely long.)

The flipside to this advice is that each time you enumerate such an IEnumerable the work to evaluate it has to be done afresh. So you need to decide for each case whether it is better to work with the lazily evaluated IEnumerable or to realize it into a List, Set, Dictionary or whatnot.

No, there isn't such constant.

XAMPP only offers MySQL (Database Server) & Apache (Webserver) in one setup and you can manage them with the xampp starter.

After the successful installation navigate to your xampp folder and execute the xampp-control.exe

Press the start Button at the mysql row.

Now you've successfully started mysql. Now there are 2 different ways to administrate your mysql server and its databases.

But at first you have to set/change the MySQL Root password. Start the Apache server and type localhost or 127.0.0.1 in your browser's address bar. If you haven't deleted anything from the htdocs folder the xampp status page appears. Navigate to security settings and change your mysql root password.

Now, you can browse to your phpmyadmin under http://localhost/phpmyadmin or download a windows mysql client for example navicat lite or mysql workbench. Install it and log in to your mysql server with your new root password.

Simply you can aadd --force at the end of the command. Like:

sudo docker rmi <docker_image_id> --force

To make it more intelligent you can add as:

sudo docker stop $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rm $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rmi $(docker images | grep <your_image_name> | awk '{print $3}') --force

Here in docker ps $1 is the first column, i.e. the Docker container ID.

And docker images $3 is the third column, i.e. the Docker image ID.

Here's an Angular friendly version:

  constructor(private location: Location, private renderer: Renderer2) {}

  download(content, fileName, mimeType) {

    const a = this.renderer.createElement('a');

    mimeType = mimeType || 'application/octet-stream';

    if (navigator.msSaveBlob) {

      navigator.msSaveBlob(new Blob([content], {
        type: mimeType
      }), fileName);
    }
    else if (URL && 'download' in a) {

      const id = GetUniqueID();

      this.renderer.setAttribute(a, 'id', id);
      this.renderer.setAttribute(a, 'href', URL.createObjectURL(new Blob([content], {
        type: mimeType
      })));

      this.renderer.setAttribute(a, 'download', fileName);

      this.renderer.appendChild(document.body, a);

      const anchor = this.renderer.selectRootElement(`#${id}`);

      anchor.click();

      this.renderer.removeChild(document.body, a);
    }
    else {
      this.location.go(`data:application/octet-stream,${encodeURIComponent(content)}`);
    }
  };

From Java Tutorial - Restrictions on Generics:

Cannot Create Instances of Type Parameters

You cannot create an instance of a type parameter. For example, the following code causes a compile-time error:

public static <E> void append(List<E> list) {
    E elem = new E();  // compile-time error
    list.add(elem);
}

As a workaround, you can create an object of a type parameter through reflection:

public static <E> void append(List<E> list, Class<E> cls) throws Exception {
    E elem = cls.newInstance();   // OK
    list.add(elem);
}

You can invoke the append method as follows:

List<String> ls = new ArrayList<>();
append(ls, String.class);

I know I'm am very late on this, but here some usefull samples:

'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select

or

'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
    .value = .value
end with

To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like

 lngLast = cells(rows.count,3).end(xlUp).row

You can install the mail package in Ubuntu with below command.

For Ubuntu -:

$ sudo apt-get install -y mailutils

For CentOs-:

$ sudo yum install -y mailx

Test Mail command-:

$ echo "Mail test" | mail -s "Subject" [email protected]

Download python setup tools from the below website:

https://pypi.python.org/pypi/setuptools

Use the tar file.

Once you download, go to the downloaded folder and run

python setup.py install

Once you do that,you will have easy_install.

Use the below then to install pip:

sudo easy_install pip

function abc() {
    var color = document.getElementById("test").style.color;
    color = (color=="red") ? "black" : "red" ;
    document.getElementById("test").style.color= color;
}

Why use GROUP BY at all?

SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players
ORDER BY player_salary DESC

Presuming the autoincrement column in customer_data is named Id, you can do:

SELECT CONCAT(title,' ',forename,' ',surname) AS name *
FROM customer c
    INNER JOIN customer_data d 
        ON c.customer_id=d.customer_id
WHERE name LIKE '%Smith%'
    AND d.ID = (
                Select Max(D2.Id)
                From customer_data As D2
                Where D2.customer_id = D.customer_id
                )
LIMIT 10, 20

Adding to what deceze said above. This is a parse error, so in order to debug a parse error, create a new file in the root named debugSyntax.php. Put this in it:

<?php

///////    SYNTAX ERROR CHECK    ////////////
error_reporting(E_ALL);
ini_set('display_errors','On');

//replace "pageToTest.php" with the file path that you want to test. 
include('pageToTest.php'); 

?>

Run the debugSyntax.php page and it will display parse errors from the page that you chose to test.

I had the same problem with a client of my company, the problem was that the driver sqljdbc4.jar, tries a convertion of character between the database and the driver. Each time that it did a request to the database, now you can imagine 650 connections concurrently, this did my sistem very very slow, for avoid this situation i add at the String of connection the following parameter:

 SendStringParametersAsUnicode=false, then te connection must be something like url="jdbc:sqlserver://IP:PORT;DatabaseName=DBNAME;SendStringParametersAsUnicode=false"

After that, the system is very very fast, as the users are very happy with the change, i hope my input be of same.

Almost all CPUs use stack. The program stack is LIFO technique with hardware supported manage.

Stack is amount of program (RAM) memory normally allocated at the top of CPU memory heap and grow (at PUSH instruction the stack pointer is decreased) in opposite direction. A standard term for inserting into stack is PUSH and for remove from stack is POP.

Stack is managed via stack intended CPU register, also called stack pointer, so when CPU perform POP or PUSH the stack pointer will load/store a register or constant into stack memory and the stack pointer will be automatic decreased xor increased according number of words pushed or poped into (from) stack.

Via assembler instructions we can store to stack:

1. CPU registers and also constants.
2. Return addresses for functions or procedures
3. Functions/procedures in/out variables
4. Functions/procedures local variables.

MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form

The inability to load the resource from an external data store beyond your control is difficult. Looking for missing functions is totally fallacious as a means to avoid suffering a timeout, as described herein: http://www.tech-101.com/support/topic/4499-issues-using-a-cdn/

from itertools import count, izip

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

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

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

To generate an area where you can specify a description for the function and each parameter for the function, type the following on the line before your function and hit Enter:

• C#: ///

• VB: '''

After jQuery 1.6, using promise seems like a better option.

var $div1 = $('#div1');
var fadeOutDone = $div1.fadeOut().promise();
// do your logic here, e.g.fetch your 2nd image url
$.get('secondimageinfo.json').done(function(data){
  fadeoOutDone.then(function(){
    $div1.html('<img src="' + data.secondImgUrl + '" alt="'data.secondImgAlt'">');
    $div1.fadeIn();
  });
});

Instead of using the ifelse as in the above example, one can also prefilter the data prior to labeling based on some threshold values, this saves a lot of work for the plotting device:

xlimit <- 36
ylimit <- 24
ggplot(myData)+geom_point(aes(myX,myY))+
    geom_label(data=myData[myData$myX > xlimit & myData$myY> ylimit,], aes(myX,myY,myLabel))
