Look at the package DBMS_Redefinition. It will rebuild the table with the new ordering. It can be done with the table online.

As Phil Brown noted, think carefully before doing this. However there is overhead in scanning the row for columns and moving data on update. Column ordering rules I use (in no particular order):

• Group related columns together.
• Not NULL columns before null-able columns.
• Frequently searched un-indexed columns first.
• Rarely filled null-able columns last.
• Static columns first.
• Updateable varchar columns later.
• Indexed columns after other searchable columns.

These rules conflict and have not all been tested for performance on the latest release. Most have been tested in practice, but I didn't document the results. Placement options target one of three conflicting goals: easy to understand column placement; fast data retrieval; and minimal data movement on updates.

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

You may use a delegate to solve this issue. Here is an example that is showing how to update a textBox using diffrent thread

public delegate void UpdateTextCallback(string message);

private void TestThread()
{
    for (int i = 0; i <= 1000000000; i++)
    {
        Thread.Sleep(1000);                
        richTextBox1.Dispatcher.Invoke(
            new UpdateTextCallback(this.UpdateText),
            new object[] { i.ToString() }
        );
    }
}
private void UpdateText(string message)
{
    richTextBox1.AppendText(message + "\n");
}

private void button1_Click(object sender, RoutedEventArgs e)
{
   Thread test = new Thread(new ThreadStart(TestThread));
   test.Start();
}

TestThread method is used by thread named test to update textBox

If you want to extract only numbers from a string the pattern "\d+" should help.

Instead of hard-coded converters, how about CSV support for Jackson (JSON processor): https://github.com/FasterXML/jackson-dataformat-csv. So core Jackson can read JSON in as POJOs, Maps, JsonNode, almost anything. And CSV support can do the same with CSV. Combine the two and it's very powerful but simple converter between multiple formats (there are backends for XML, YAML already, and more being added).

An article that shows how to do this can be found here.

It is possible to pass arrays to functions, and there are no special requirements for dealing with them. Are you sure that the array you are passing to to your function actually has an element at [0]?

It will group by the column position you put after the group by clause.

for example if you run 'SELECT SALESMAN_NAME, SUM(SALES) FROM SALES GROUP BY 1' it will group by SALESMAN_NAME.

One risk on doing that is if you run 'Select *' and for some reason you recreate the table with columns on a different order, it will give you a different result than you would expect.

Your regex says the following:

/^         - if the line starts with
(          - start a capture group
Clinton|   - "Clinton" 
|          - or
[^Bush]    - Any single character except "B", "u", "s" or "h"
|          - or
Reagan)   - "Reagan". End capture group.
/i         - Make matches case-insensitive 

So, in other words, your middle part of the regex is screwing you up. As it is a "catch-all" kind of group, it will allow any line that does not begin with any of the upper or lower case letters in "Bush". For example, these lines would match your regex:

Our president, George Bush
In the news today, pigs can fly
012-3123 33

You either make a negative look-ahead, as suggested earlier, or you simply make two regexes:

if( ($string =~ m/^(Clinton|Reagan)/i) and
    ($string !~ m/^Bush/i) ) {
   print "$string\n";
}

As mirod has pointed out in the comments, the second check is quite unnecessary when using the caret (^) to match only beginning of lines, as lines that begin with "Clinton" or "Reagan" could never begin with "Bush".

However, it would be valid without the carets.

Both choices refer to what algorithm the identity provider uses to sign the JWT. Signing is a cryptographic operation that generates a "signature" (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with.

• RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and it uses a public/private key pair: the identity provider has a private (secret) key used to generate the signature, and the consumer of the JWT gets a public key to validate the signature. Since the public key, as opposed to the private key, doesn't need to be kept secured, most identity providers make it easily available for consumers to obtain and use (usually through a metadata URL).

• HS256 (HMAC with SHA-256), on the other hand, involves a combination of a hashing function and one (secret) key that is shared between the two parties used to generate the hash that will serve as the signature. Since the same key is used both to generate the signature and to validate it, care must be taken to ensure that the key is not compromised.

If you will be developing the application consuming the JWTs, you can safely use HS256, because you will have control on who uses the secret keys. If, on the other hand, you don't have control over the client, or you have no way of securing a secret key, RS256 will be a better fit, since the consumer only needs to know the public (shared) key.

Since the public key is usually made available from metadata endpoints, clients can be programmed to retrieve the public key automatically. If this is the case (as it is with the .Net Core libraries), you will have less work to do on configuration (the libraries will fetch the public key from the server). Symmetric keys, on the other hand, need to be exchanged out of band (ensuring a secure communication channel), and manually updated if there is a signing key rollover.

Auth0 provides metadata endpoints for the OIDC, SAML and WS-Fed protocols, where the public keys can be retrieved. You can see those endpoints under the "Advanced Settings" of a client.

The OIDC metadata endpoint, for example, takes the form of https://{account domain}/.well-known/openid-configuration. If you browse to that URL, you will see a JSON object with a reference to https://{account domain}/.well-known/jwks.json, which contains the public key (or keys) of the account.

If you look at the RS256 samples, you will see that you don't need to configure the public key anywhere: it's retrieved automatically by the framework.

I solved this problem.

My Java version was the 1.6 and I found that was using 1.7 with CDI however after that I changed the Java version to 1.7 and import the package javax.faces.bean.ManagedBean and everything worked.

Thanks @PM77-1

you can watch all files like this

tsc *.ts --watch

If your your list is dynamically generated with unknown number and your target is to always have last div in a new line set last div class to "col-xl-12" and remove other classes so it will always take a full row.

This is a copy of your code corrected so that last div always occupy a full row (I although removed unnecessary classes).

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">_x000D_
<div class="grid">_x000D_
  <div class="row">_x000D_
    <div class="col-sm-3">Under me should be a DIV</div>_x000D_
    <div class="col-md-6 col-sm-5">Under me should be a DIV</div>_x000D_
    <div class="col-xl-12">I am the last DIV and I always take a full row for my self!!</div>_x000D_
  </div>_x000D_
</div>

The only way to execute PHP from JS is AJAX. You can send data to server (for eg, GET /ajax.php?do=someFunction) then in ajax.php you write:

function someFunction() {
    echo 'Answer';
}

if ($_GET['do'] === "someFunction") {
    someFunction();
}

and then, catch the answer with JS (i'm using jQuery for making AJAX requests)

Probably you'll need some format of answer. See JSON or XML, but JSON is easy to use with JavaScript. In PHP you can use function json_encode($array); which gets array as argument.

Modulo would be the correct answer, but if you're doing it manually this should work.

num = input("Enter a number: ")
div = input("Enter a divisor: ")

while num >= div:
    num -= div
print num

set JAVA_HOME variable and ad JAVA_HOME/bin to evnrionment path variable.

There are actually several approaches to do this. Some require more overhead than others, and some are considered better than others.

In no particular order:

1. Use AJAX to get the data you need from the server.
2. Echo the data into the page somewhere, and use JavaScript to get the information from the DOM.
3. Echo the data directly to JavaScript.

In this post, we'll examine each of the above methods, and see the pros and cons of each, as well as how to implement them.

1. Use AJAX to get the data you need from the server

This method is considered the best, because your server side and client side scripts are completely separate.

Pros

• Better separation between layers - If tomorrow you stop using PHP, and want to move to a servlet, a REST API, or some other service, you don't have to change much of the JavaScript code.
• More readable - JavaScript is JavaScript, PHP is PHP. Without mixing the two, you get more readable code on both languages.
• Allows for asynchronous data transfer - Getting the information from PHP might be time/resources expensive. Sometimes you just don't want to wait for the information, load the page, and have the information reach whenever.
• Data is not directly found on the markup - This means that your markup is kept clean of any additional data, and only JavaScript sees it.

Cons

• Latency - AJAX creates an HTTP request, and HTTP requests are carried over network and have network latencies.
• State - Data fetched via a separate HTTP request won't include any information from the HTTP request that fetched the HTML document. You may need this information (e.g., if the HTML document is generated in response to a form submission) and, if you do, will have to transfer it across somehow. If you have ruled out embedding the data in the page (which you have if you are using this technique) then that limits you to cookies/sessions which may be subject to race conditions.

Implementation Example

With AJAX, you need two pages, one is where PHP generates the output, and the second is where JavaScript gets that output:

get-data.php

/* Do some operation here, like talk to the database, the file-session
 * The world beyond, limbo, the city of shimmers, and Canada.
 *
 * AJAX generally uses strings, but you can output JSON, HTML and XML as well.
 * It all depends on the Content-type header that you send with your AJAX
 * request. */

echo json_encode(42); // In the end, you need to echo the result.
                      // All data should be json_encode()d.

                      // You can json_encode() any value in PHP, arrays, strings,
                      //even objects.

index.php (or whatever the actual page is named like)

<!-- snip -->
<script>
    function reqListener () {
      console.log(this.responseText);
    }

    var oReq = new XMLHttpRequest(); // New request object
    oReq.onload = function() {
        // This is where you handle what to do with the response.
        // The actual data is found on this.responseText
        alert(this.responseText); // Will alert: 42
    };
    oReq.open("get", "get-data.php", true);
    //                               ^ Don't block the rest of the execution.
    //                                 Don't wait until the request finishes to
    //                                 continue.
    oReq.send();
</script>
<!-- snip -->

The above combination of the two files will alert 42 when the file finishes loading.

• XMLHttpRequest object reference - MDN
• How do I return the response from an asynchronous call?

2. Echo the data into the page somewhere, and use JavaScript to get the information from the DOM

This method is less preferable to AJAX, but it still has its advantages. It's still relatively separated between PHP and JavaScript in a sense that there is no PHP directly in the JavaScript.

Pros

• Fast - DOM operations are often quick, and you can store and access a lot of data relatively quickly.

Cons

• Potentially Unsemantic Markup - Usually, what happens is that you use some sort of <input type=hidden> to store the information, because it's easier to get the information out of inputNode.value, but doing so means that you have a meaningless element in your HTML. HTML has the <meta> element for data about the document, and HTML 5 introduces data-* attributes for data specifically for reading with JavaScript that can be associated with particular elements.
• Dirties up the Source - Data that PHP generates is outputted directly to the HTML source, meaning that you get a bigger and less focused HTML source.
• Harder to get structured data - Structured data will have to be valid HTML, otherwise you'll have to escape and convert strings yourself.
• Tightly couples PHP to your data logic - Because PHP is used in presentation, you can't separate the two cleanly.

Implementation Example

With this, the idea is to create some sort of element which will not be displayed to the user, but is visible to JavaScript.

index.php

<!-- snip -->
<div id="dom-target" style="display: none;">
    <?php
        $output = "42"; // Again, do some operation, get the output.
        echo htmlspecialchars($output); /* You have to escape because the result
                                           will not be valid HTML otherwise. */
    ?>
</div>
<script>
    var div = document.getElementById("dom-target");
    var myData = div.textContent;
</script>
<!-- snip -->

3. Echo the data directly to JavaScript

This is probably the easiest to understand.

Pros

• Very easily implemented - It takes very little to implement this, and understand.
• Does not dirty source - Variables are outputted directly to JavaScript, so the DOM is not affected.

Cons

• Tightly couples PHP to your data logic - Because PHP is used in presentation, you can't separate the two cleanly.

Implementation Example

Implementation is relatively straightforward:

<!-- snip -->
<script>
    var data = <?php echo json_encode("42", JSON_HEX_TAG); ?>; // Don't forget the extra semicolon!
</script>
<!-- snip -->

Good luck!

It sounds like you may be wanting to access the viewport of the device. You can do this by inserting this meta tag in your header.

<meta name="viewport" content="width=device-width, initial-scale=1.0">

This is helped to me for bootstrap active nav class in Laravel 5.2:

<li class="{{ Request::path() == '/' ? 'active' : '' }}"><a href="/">Home</a></li>
<li class="{{ Request::path() == 'about' ? 'active' : '' }}"><a href="/about">About</a></li>

You can create category for the UiView and override the touchesBegan meathod as follows.

It is working fine for me.And it is centralize solution for this problem.

#import "UIView+Keyboard.h"
@implementation UIView(Keyboard)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.window endEditing:true];
    [super touchesBegan:touches withEvent:event];
}
@end

Just use date($format, strtotime($date,' LAST SUNDAY + 1 DAY'));

from within the vscode terminal,

git remote set-url origin https://<your github username>:<your password>@github.com/<your github username>/<your github repository name>.git

for the quickest, but not so encouraged way.

For me the issue was caused by config file automatically genearted by importing the WSDL. I updated the binding to from basicHttpBinding to customBinding. Adding additional exception handling did not help pointing this out.

Before

<basicHttpBinding>
            <binding name="ServiceName">
                <security mode="Transport" />
            </binding>
        </basicHttpBinding>`

After

<customBinding>
        <binding name="ServiceName">
          <textMessageEncoding messageVersion="Soap12" />
          <httpsTransport />
        </binding>
      </customBinding>`

b = dict(zip(a[::2], a[1::2]))

If a is large, you will probably want to do something like the following, which doesn't make any temporary lists like the above.

from itertools import izip
i = iter(a)
b = dict(izip(i, i))

In Python 3 you could also use a dict comprehension, but ironically I think the simplest way to do it will be with range() and len(), which would normally be a code smell.

b = {a[i]: a[i+1] for i in range(0, len(a), 2)}

So the iter()/izip() method is still probably the most Pythonic in Python 3, although as EOL notes in a comment, zip() is already lazy in Python 3 so you don't need izip().

i = iter(a)
b = dict(zip(i, i))

If you want it on one line, you'll have to cheat and use a semicolon. ;-)

This works fine for me:

ALTER TABLE 'users'
ADD COLUMN 'count' SMALLINT(6) NOT NULL AFTER 'lastname',
ADD COLUMN 'log' VARCHAR(12) NOT NULL AFTER 'count',
ADD COLUMN 'status' INT(10) UNSIGNED NOT NULL AFTER 'log';

git config user.name
git config user.email

I believe these are the commands you are looking for.

Here is where I found them: http://alvinalexander.com/git/git-show-change-username-email-address

The answer is simple: people say ruby is slow because it is slow based on measured comparisons to other languages. Bear in mind, though, "slow" is relative. Often, ruby and other "slow" languages are plenty fast enough.

I managed to remove the errors by disabling the validations:

{
    "javascript.validate.enable": false,
    "html.validate.styles": false,
    "html.validate.scripts": false,
    "css.validate": false,
    "scss.validate": false
}

Obs: My project is a PWA using StyledComponents, React, Flow, Eslint and Prettier.

Global variables are almost never a good thing (maybe an exception or two out there...). In this case, it looks like you really just want to export your "name" variable. E.g.,

// module.js
var name = "foobar";
// export it
exports.name = name;

Then, in main.js...

//main.js
// get a reference to your required module
var myModule = require('./module');

// name is a member of myModule due to the export above
var name = myModule.name;

Using Transformer Factory:-

public static String printSoapMessage(final SOAPMessage soapMessage) throws TransformerFactoryConfigurationError,
            TransformerConfigurationException, SOAPException, TransformerException
    {
        final TransformerFactory transformerFactory = TransformerFactory.newInstance();
        final Transformer transformer = transformerFactory.newTransformer();

        // Format it
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

        final Source soapContent = soapMessage.getSOAPPart().getContent();

        final ByteArrayOutputStream streamOut = new ByteArrayOutputStream();
        final StreamResult result = new StreamResult(streamOut);
        transformer.transform(soapContent, result);

        return streamOut.toString();
    }

Replace Operator:=xlOr with Operator:=xlAnd between your criteria. See below the amended script

The stack is the memory set aside as scratch space for a thread of execution. When a function is called, a block is reserved on the top of the stack for local variables and some bookkeeping data. When that function returns, the block becomes unused and can be used the next time a function is called. The stack is always reserved in a LIFO (last in first out) order; the most recently reserved block is always the next block to be freed. This makes it really simple to keep track of the stack; freeing a block from the stack is nothing more than adjusting one pointer.

The heap is memory set aside for dynamic allocation. Unlike the stack, there's no enforced pattern to the allocation and deallocation of blocks from the heap; you can allocate a block at any time and free it at any time. This makes it much more complex to keep track of which parts of the heap are allocated or free at any given time; there are many custom heap allocators available to tune heap performance for different usage patterns.

Each thread gets a stack, while there's typically only one heap for the application (although it isn't uncommon to have multiple heaps for different types of allocation).

To answer your questions directly:

To what extent are they controlled by the OS or language runtime?

The OS allocates the stack for each system-level thread when the thread is created. Typically the OS is called by the language runtime to allocate the heap for the application.

What is their scope?

The stack is attached to a thread, so when the thread exits the stack is reclaimed. The heap is typically allocated at application startup by the runtime, and is reclaimed when the application (technically process) exits.

What determines the size of each of them?

The size of the stack is set when a thread is created. The size of the heap is set on application startup, but can grow as space is needed (the allocator requests more memory from the operating system).

What makes one faster?

The stack is faster because the access pattern makes it trivial to allocate and deallocate memory from it (a pointer/integer is simply incremented or decremented), while the heap has much more complex bookkeeping involved in an allocation or deallocation. Also, each byte in the stack tends to be reused very frequently which means it tends to be mapped to the processor's cache, making it very fast. Another performance hit for the heap is that the heap, being mostly a global resource, typically has to be multi-threading safe, i.e. each allocation and deallocation needs to be - typically - synchronized with "all" other heap accesses in the program.

You should use the flex or flex-basis property rather than width. Read more on MDN.

.flexbox .red {
  flex: 0 0 25em;
}

The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. It contains:

flex-grow: 0;     /* do not grow   - initial value: 0 */
flex-shrink: 0;   /* do not shrink - initial value: 1 */
flex-basis: 25em; /* width/height  - initial value: auto */

A simple demo shows how to set the first column to 50px fixed width.

.flexbox {_x000D_
  display: flex;_x000D_
}_x000D_
.red {_x000D_
  background: red;_x000D_
  flex: 0 0 50px;_x000D_
}_x000D_
.green {_x000D_
  background: green;_x000D_
  flex: 1;_x000D_
}_x000D_
.blue {_x000D_
  background: blue;_x000D_
  flex: 1;_x000D_
}

<div class="flexbox">_x000D_
  <div class="red">1</div>_x000D_
  <div class="green">2</div>_x000D_
  <div class="blue">3</div>_x000D_
</div>

The quirky syntax using conditions on the target (described by Mads) is the only supported way to perform conditional execution in core ANT.

ANT is not a programming language and when things get complicated I choose to embed a script within my build as follows:

<target name="prepare-copy" description="copy file based on condition">
    <groovy>
        if (properties["some.condition"] == "true") {
            ant.copy(file:"${properties["some.dir"]}/true", todir:".")
        }
    </groovy>
</target>

ANT supports several languages (See script task), my preference is Groovy because of it's terse syntax and because it plays so well with the build.

Apologies, David I am not a fan of ant-contrib.

I did not modify your code for this solution, I wrote my own instead. My solution isn't quite what you asked for, but maybe you could build on it with existing knowledge. I commented the code as well so you know what exactly I'm doing with the changes.

As a solution to "avoid setting the height in JavaScript", I just made 'maxHeight' a parameter in the JS function called toggleHeight. Now it can be set in the HTML for each div of class expandable.

I'll say this up front, I'm not super experienced with front-end languages, and there's an issue where I need to click the 'Show/hide' button twice initially before the animation starts. I suspect it's an issue with focus.

The other issue with my solution is that you can actually figure out what the hidden text is without pressing the show/hide button just by clicking in the div and dragging down, you can highlight the text that's not visible and paste it to a visible space.

My suggestion for a next step on top of what I've done is to make it so that the show/hide button changes dynamically. I think you can figure out how to do that with what you already seem to know about showing and hiding text with JS.

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

It seems there are 2 adb version in your system. Please find them out and keep the adb in your Android SDK folder only, delete all others folders that including adb file. You can find out which adb you are using from Application Monitor:

It might be a problem if the adb is not the one in you Android SDK folder.

In my case, I found I was running adb from here:

/Library/Application Support/RSupport/Mobizen2

after deleting the Mobizen2 folder, then all adb commands work fine.

FYI this kind of code works (you can find it ugly, it is your right :) ) :

def list = null
list.each { println it }
soSomething()

In other words, this code has null/empty checks both useless:

if (members && !members.empty) {
    members.each { doAnotherThing it }
}

def doAnotherThing(def member) {
  // Some work
}

You need to do a while loop to get the result from the SQL query, like this:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )    
FROM modul1open) ORDER BY idM1O LIMIT 1";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

    // If you want to display all results from the query at once:
    print_r($row);

    // If you want to display the results one by one
    echo $row['column1'];
    echo $row['column2']; // etc..

}

Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli or PDO extension. You can read more about that here.

Since you are using jQuery, you might as well use the each method... Also, it seems like everything is a value of the property 'd' in this JS Object [Notation].

$.each(result.d,function(i) {
    // In case there are several values in the array 'd'
    $.each(this,function(j) {
        // Apparently doesn't work...
        alert(this.EmployeeName);
        // What about this?
        alert(result.d[i][j]['EmployeeName']);
        // Or this?
        alert(result.d[i][j].EmployeeName);
    });
});

That should work. if not, then maybe you can give us a longer example of the JSON.

Edit: If none of this stuff works then I'm starting to think there might be something wrong with the syntax of your JSON.

In Ubuntu 18.04, below are the steps that I followed.

python3 -m pip install --upgrade pip

For some reason you will be getting an error, and that be fixed by making bash forget the wrongly referenced locations using the following command.

hash -r pip

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

Edit

As pointed out in @Kevin's answer, the correct way would be to use optional type cast operator as?. You can read more about it on the section Optional Chaining sub section Downcasting.

Edit 2

As pointed on the other answer by user @KPM, using the is operator is the right way to do it.

this is a programatical approach:

 view.setVisibility(View.GONE); //For GONE
 view.setVisibility(View.INVISIBLE); //For INVISIBLE
 view.setVisibility(View.VISIBLE); //For VISIBLE

Even later response, but I just ran into a similar issue and ended up writing my own Image link HtmlHelper extension.

You can find an implementation of it on my blog in the link above.

Just added in case someone is hunting down an implementation.

function removeLocationHash(){
    var noHashURL = window.location.href.replace(/#.*$/, '');
    window.history.replaceState('', document.title, noHashURL) 
}

window.addEventListener("load", function(){
    removeLocationHash();
});

Trying to find a good solution for this now, I happened upon the FeedEk jQuery RSS/ATOM Feed Plugin that does a great job of parsing and displaying RSS and Atom feeds via the jQuery Feed API. For a basic XML-based RSS feed, I've found it works like a charm and needs no server-side scripts or other CORS workarounds for it to run even locally.

Continuous Integration: The practice of merging the development work with the main branch constantly so that the code has been tested as often as possible to catch issues early.

Continuous Delivery: Continuous delivery of code to an environment once the code is ready to ship. This could be staging or production. The idea is the product is delivered to a user base, which can be QA's or customers for review and inspection.

Unit test during the Continuous Integration phase can not catch all the bugs and business logic, particularly design issues that is why we need QA, or staging environment for testing.

Continuous Deployment: The deployment or release of code as soon as it's ready. Continuous Deployment requires Continuous Integration and Continuous Delivery otherwise the code quality won't be guarantee in a release.

Hope this helps anyone facing same issue

To know exactly where has occurred, since the running program doesn't mention it as a error with line number

Make sure to add assert after loading the image/frame

For image

image = cv2.imread('myimage.png')
assert not isinstance(image,type(None)), 'image not found'

For video

cap = cv2.VideoCapture(0)

    while(cap.isOpened()):

        # Capture frame-by-frame
        ret, frame = cap.read()
        if ret:
            assert not isinstance(frame,type(None)), 'frame not found'

Helped me solve a similar issue, in a long script

I had the same issue but solved it by using !important. I forgot about the inheritance in CSS. Just a tip to check first.

Your regex looks correct, but you're splitting with it instead of matching with it. You want something like this:

// Untested code
Matcher matcher = Pattern.compile("<%=(.*?)%>").matcher(str);
while (matcher.find()) {
    System.out.println(matcher.group());
}

Don't do: mkdir -m 777 -p a/b/c since that will only set permission 777 on the last directory, c; a and b will be created with the default permission from your umask.

Instead to create any new directories with permission 777, run mkdir -p in a subshell where you override the umask:

(umask u=rwx,g=rwx,o=rwx && mkdir -p a/b/c)

Note that this won't change the permissions if any of a, b and c already exist though.

The /g modifier is used to perform a global match (find all matches rather than stopping after the first)

You can use \d for digit, as it is shorter than [0-9].

JavaScript:

var s = "04.07.2012"; 
echo(s.replace(/\d/g, "X"));

Output:

XX.XX.XXXX

You can assign a class to many elements. You can also assign more than one class to an element, eg.

<button class="btn span4" ..>

in Bootstrap. You can assign the id only to one. So if you want to make many elements look the same, eg. list items, you choose class. If you want to trigger certain actions on an element using JavaScript you will probably use id.

Here's some more good practices around Timer use:

http://tech.puredanger.com/2008/09/22/timer-rules/

In general, I'd use Timer for quick and dirty stuff and Executor for more robust usage.

Sometimes a lot of troubles with it. In attribute value of datapicker data is 28-06-2014, but datepicker is show or today or nothing. I decided it in a such way:

<input type="text" class="form-control datepicker" data-value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" />

I added to the input of datapicker attribute data-value, because if call jQuery(this).val() OR jQuery(this).attr('value') - nothing works. I decided init in cycle each datapicker and take its value from attribute data-value:

 $("form .datepicker").each(function() {
        var time = jQuery(this).data('value');
        time = time.split('-');
        $(this).datepicker('setDate', new Date(time[2], time[1], time[0], 0, 0, 0));
    });

and it is works fine =)

Are you using position: relative?

Try to set position: relative and then z-index because you want this div has a z-index in relation with other div.

By the way, your browser is important to check if it working or not. Neither IE or Firefox is a good one.

If you are using Microsoft Drivers 3.1, 3.0, and 2.0. Please check your PHP version already install with IIS.

Use this script to check the php version:

<?php echo phpinfo(); ?>

OR

If you have installed PHP Manager in IIS using web platform Installer you can check the version from it.

Then:
If you are using new PHP version (5.6) please download Drivers from here

For PHP version Lower than 5.6 - please download Drivers from here

• PHP Driver version 3.1 requires PHP 5.4.32, or PHP 5.5.16, or later.
• PHP Driver version 3.0 requires PHP 5.3.0 or later. If possible, use PHP 5.3.6, or later.
• PHP Driver version 2.0 driver works with PHP 5.2.4 or later, but not with PHP 5.4. If possible, use PHP 5.2.13, or later.

Then use the PHP Manager to add that downloaded drivers into php config file.You can do it as shown below (browse the files and press OK). Then Restart the IIS Server

If this method not work please change the php version and try to run your php script.

Tip:Change the php version to lower and try to understand what happened.then you can download relevant drivers.

When I want the UI to be able to update its display while waiting for a task to complete, I use a while-loop that tests IsAlive on the thread:

    Thread t = new Thread(() => someMethod(parameters));
    t.Start();
    while (t.IsAlive)
    {
        Thread.Sleep(500);
        Application.DoEvents();
    }

The script package does exactly what you're looking for: https://atom.io/packages/script

The package's documentation also contains the key mappings, which you can easily customize.

You need to code your html using absolute path for images. By Absolute path means you have to upload the images in a server and in the src attribute of images you have to give the direct path like this <img src="http://yourdomain.com/images/example.jpg">.

Below is the PHP code for your refference :- Its taken from http://www.php.net/manual/en/function.mail.php

<?php
// multiple recipients
$to  = '[email protected]' . ', '; // note the comma
$to .= '[email protected]';

// subject
$subject = 'Birthday Reminders for August';

// message
$message = '
  <p>Here are the birthdays upcoming in August!</p>
';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";

// Additional headers
$headers .= 'To: Mary <[email protected]>, Kelly <[email protected]>' . "\r\n";
$headers .= 'From: Birthday Reminder <[email protected]>' . "\r\n";


// Mail it
mail($to, $subject, $message, $headers);
?>

You should use

-moz-appearance:none;
-webkit-appearance:none;
-o-appearance:none;

Then you get rid of the default checkbox image/style and can style it. Anyway a border will still be there in Firefox

There's a lot of typedef going on here. Personally I'm against "hiding the asterisk", i.e. typedef:ing pointer types into something that doesn't look like a pointer. In C, pointers are quite important and really affect the code, there's a lot of difference between foo and foo *.

Many of the answers are also confused about this, I think.

Your allocation of an array of Chess values, which are pointers to values of type chess (again, a very confusing nomenclature that I really can't recommend) should be like this:

Chess *array = malloc(n * sizeof *array);

Then, you need to initialize the actual instances, by looping:

for(i = 0; i < n; ++i)
  array[i] = NULL;

This assumes you don't want to allocate any memory for the instances, you just want an array of pointers with all pointers initially pointing at nothing.

If you wanted to allocate space, the simplest form would be:

for(i = 0; i < n; ++i)
  array[i] = malloc(sizeof *array[i]);

See how the sizeof usage is 100% consistent, and never starts to mention explicit types. Use the type information inherent in your variables, and let the compiler worry about which type is which. Don't repeat yourself.

Of course, the above does a needlessly large amount of calls to malloc(); depending on usage patterns it might be possible to do all of the above with just one call to malloc(), after computing the total size needed. Then you'd still need to go through and initialize the array[i] pointers to point into the large block, of course.

As explained in the accepted answer, https://stackoverflow.com/a/18665488/4038790, you need to check via a server.

Because there's no reliable way to check this in the browser, I suggest you build yourself a quick server endpoint that you can use to check if any url is loadable via iframe. Once your server is up and running, just send a AJAX request to it to check any url by providing the url in the query string as url (or whatever your server desires). Here's the server code in NodeJs:

const express = require('express')_x000D_
const app = express()_x000D_
_x000D_
app.get('/checkCanLoadIframeUrl', (req, res) => {_x000D_
  const request = require('request')_x000D_
  const Q = require('q')_x000D_
_x000D_
  return Q.Promise((resolve) => {_x000D_
    const url = decodeURIComponent(req.query.url)_x000D_
_x000D_
    const deafultTimeout = setTimeout(() => {_x000D_
      // Default to false if no response after 10 seconds_x000D_
      resolve(false)_x000D_
    }, 10000)_x000D_
_x000D_
    request({_x000D_
        url,_x000D_
        jar: true /** Maintain cookies through redirects */_x000D_
      })_x000D_
      .on('response', (remoteRes) => {_x000D_
        const opts = (remoteRes.headers['x-frame-options'] || '').toLowerCase()_x000D_
        resolve(!opts || (opts !== 'deny' && opts !== 'sameorigin'))_x000D_
        clearTimeout(deafultTimeout)_x000D_
      })_x000D_
      .on('error', function() {_x000D_
        resolve(false)_x000D_
        clearTimeout(deafultTimeout)_x000D_
      })_x000D_
  }).then((result) => {_x000D_
    return res.status(200).json(!!result)_x000D_
  })_x000D_
})_x000D_
_x000D_
app.listen(process.env.PORT || 3100)

I need something similiar with angular reactive form:

let myMap = new Map().set(0, {status: 'VALID'}).set(1, {status: 'INVALID'});
let mapToArray = Array.from(myMap.values());
let isValid = mapToArray.every(x => x.status === 'VALID');

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

You can either use (on the h4 elements, as they are block by default)

display: inline-block;

Or you can float the elements to the left/rght

float: left;

Just don't forget to clear the floats after

clear: left;

More visual example for the float left/right option as shared below by @VSB:

<h4> _x000D_
    <div style="float:left;">Left Text</div>_x000D_
    <div style="float:right;">Right Text</div>_x000D_
    <div style="clear: left;"/>_x000D_
</h4>

Let us put it clear that most of the time in production code, we use abstract factory pattern because class A is programmed with interface B. And A needs to create instances of B. So A has to have a factory object to produce instances of B. So A is not dependent on any concrete instance of B. Hope it helps.

No behaviors can be set by CSS. The only way to disable something in CSS is to make it invisible by either setting display:none or simply putting div with transparent img all over it and changing their z-orders to disable user focusing on it with mouse. Even though, user will still be able to focus with tab from another field.

You can use the following to get the previous URL.

var oldURL = document.referrer;
alert(oldURL);

I have encountered the same error as well. I am sure my indentation did not have any problem. Only restarting the python sell solved the problem.

There is this tool ChangeVersion ^[1]

Kind of an embarrassing occurrence of this error for me, but if it helps the cause...

Make sure you have Ubuntu for desktop, part 1 of this wikihow:

Nobody's perfect :)

For small applications it is fine to use Timer and TimerTask as Rohit mentioned but in web applications I would use Quartz Scheduler to schedule jobs and to perform such periodic jobs.

See tutorials for Quartz scheduling.

var minRows = 5;
var maxRows = 26;
function ResizeTextarea(id) {
    var t = document.getElementById(id);
    if (t.scrollTop == 0)   t.scrollTop=1;
    while (t.scrollTop == 0) {
        if (t.rows > minRows)
                t.rows--; else
            break;
        t.scrollTop = 1;
        if (t.rows < maxRows)
                t.style.overflowY = "hidden";
        if (t.scrollTop > 0) {
            t.rows++;
            break;
        }
    }
    while(t.scrollTop > 0) {
        if (t.rows < maxRows) {
            t.rows++;
            if (t.scrollTop == 0) t.scrollTop=1;
        } else {
            t.style.overflowY = "auto";
            break;
        }
    }
}

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

If you get this error for your Flutter App's Android APK, in your app/build.gradle file under defaultConfig {}

comment out

versionCode flutterVersionCode.toInteger()
versionName flutterVersionName

and add

versionCode 2
versionName "2"

or "previous version code" + 1.

For .net Core in GET method, you can do like this:

 StringValues value1;
 string DeviceId = string.Empty;

  if (Request.Headers.TryGetValue("param1", out value1))
      {
                DeviceId = value1.FirstOrDefault();
      }

What about /usr/share/dict/words on any Unix system? How many words are we talking about? Like OED-Unabridged?

sql = """\
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
"""

[edit in responese to comment]
Having an SQL string inside a method does NOT mean that you have to "tabulate" it:

>>> class Foo:
...     def fubar(self):
...         sql = """\
... select *
... from frobozz
... where zorkmids > 10
... ;"""
...         print sql
...
>>> Foo().fubar()
select *
from frobozz
where zorkmids > 10
;
>>>

You are mixing mysql and mysqli

Change these lines:

$sql = mysql_query("SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysql_num_rows($sql);

to

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

Make as shown.

FRONT-END OPTION

I made this code specifically for those who can't change any settings on the backend. In this case the best way to prevent a very long cache is with:

new Date().getTime()

However, for most programmers the cache can be a few minutes or hours so the simple code above ends up forcing all users to download "the each page browsed". To specify how long this item will remain without reloading I made this code and left several examples below:

// cache-expires-after.js v1
function cacheExpiresAfter(delay = 1, prefix = '', suffix = '') { // seconds
    let now = new Date().getTime().toString();
    now = now.substring(now.length - 11, 10); // remove decades and milliseconds
    now = parseInt(now / delay).toString();
    return prefix + now + suffix;
};

// examples (of the delay argument):
// the value changes every 1 second
var cache = cacheExpiresAfter(1);
// see the sync
setInterval(function(){
    console.log(cacheExpiresAfter(1), new Date().getSeconds() + 's');
}, 1000);

// the value changes every 1 minute
var cache = cacheExpiresAfter(60);
// see the sync
setInterval(function(){
    console.log(cacheExpiresAfter(60), new Date().getMinutes() + 'm:' + new Date().getSeconds() + 's');
}, 1000);

// the value changes every 5 minutes
var cache = cacheExpiresAfter(60 * 5); // OR 300

// the value changes every 1 hour
var cache = cacheExpiresAfter(60 * 60); // OR 3600

// the value changes every 3 hours
var cache = cacheExpiresAfter(60 * 60 * 3); // OR 10800

// the value changes every 1 day
var cache = cacheExpiresAfter(60 * 60 * 24); // OR 86400

// usage example:
let head = (document.head || document.getElementsByTagName('head')[0]);
let script = document.createElement('script');
script.setAttribute('src', '//unpkg.com/[email protected]/dist/sweetalert.min.js' + cacheExpiresAfter(60 * 5, '?'));
head.append(script);

// this works?
let waitSwal = setInterval(function() {
    if (window.swal) {
        clearInterval(waitSwal);
        swal('Script successfully injected', script.outerHTML);
    };
}, 100);

This also works:

^([1-9]|[0-1][0-2])$

[1-9] matches single digits between 1 and 9

[0-1][0-2] matches double digits between 10 and 12

There are some good examples here

According to Joshua Bloch (Effective Java), you should use private constructor which always throws exception. That will finally discourage user to create instance of util class.

Marking class abstract is not recommended because is abstract suggests reader that class is designed for inheritance.

An exception is a class like any other class, except that it extends from Exception. So if you create your own class

public class MyCustomException extends Exception

you can throw such an instance with

   throw new MyCustomException( ... );
   //using whatever constructor params you decide to use

And this might be an interesting read

If you are in Mac OS, you need to open the /usr/local/etc/rabbitmq/rabbitmq-env.conf and set NODE_IP_ADDRESS=, it used to be 127.0.0.1. Then add another user as the accepted answer suggested. After that, restart rabbitMQ, brew services restart rabbitmq

Based on Guy Daher's answer.

I try to avoid using ? because it can cause an application crash if the GetCurrentContext() returns nil.

I would do nil check if statement:

class CustomView: UIView 
{    
    override func draw(_ rect: CGRect) 
    {
        super.draw(rect)
        if let context = UIGraphicsGetCurrentContext()
        {
            context.setStrokeColor(UIColor.gray.cgColor)
            context.setLineWidth(1)
            context.move(to: CGPoint(x: 0, y: bounds.height))
            context.addLine(to: CGPoint(x: bounds.width, y: bounds.height))
            context.strokePath()
        }
    }
}

I have uninstalled jupyter, notebook and ipython, and installed jupyterlab. It is working for now (with just a few libraries installed and Python 3.6.8.

Something to discard: Uninstalling Python 3.7 completely with his libraries and reverting to 3.6 doesn't fix it, although it improves it, it works intermittently now (but once sth doesn't work properly, things start to get worse and worse, so I did the above).

Try this:

var s = ["<a href='", url, "'>click here</a>"].join("");

It works for me. The Java code works exactly as you wrote it. In the tester, the input string should be:

This is a string.
This is a long string.

...with a real linefeed. You can't use:

This is a string.\nThis is a long string.

...because it treats \n as the literal sequence backslash 'n'.

Some sites are detecting this:

function d() {
try {
    if (window.document.$cdc_asdjflasutopfhvcZLmcfl_.cache_)
        return !0
} catch (e) {}

try {
    //if (window.document.documentElement.getAttribute(decodeURIComponent("%77%65%62%64%72%69%76%65%72")))
    if (window.document.documentElement.getAttribute("webdriver"))
        return !0
} catch (e) {}

try {
    //if (decodeURIComponent("%5F%53%65%6C%65%6E%69%75%6D%5F%49%44%45%5F%52%65%63%6F%72%64%65%72") in window)
    if ("_Selenium_IDE_Recorder" in window)
        return !0
} catch (e) {}

try {
    //if (decodeURIComponent("%5F%5F%77%65%62%64%72%69%76%65%72%5F%73%63%72%69%70%74%5F%66%6E") in document)
    if ("__webdriver_script_fn" in document)
        return !0
} catch (e) {}

Yes, something like this:

SELECT
    id,
    action_heading,
    CASE
        WHEN action_type = 'Income' THEN action_amount
        ELSE NULL
    END AS income_amt,
    CASE
        WHEN action_type = 'Expense' THEN action_amount
        ELSE NULL
    END AS expense_amt

FROM tbl_transaction;

As other answers have pointed out, MySQL also has the IF() function to do this using less verbose syntax. I generally try to avoid this because it is a MySQL-specific extension to SQL that isn't generally supported elsewhere. CASE is standard SQL and is much more portable across different database engines, and I prefer to write portable queries as much as possible, only using engine-specific extensions when the portable alternative is considerably slower or less convenient.

Just as @Saravana mentioned:

flatmap is better but there are other ways to achieve the same

 listStream.reduce(new ArrayList<>(), (l1, l2) -> {
        l1.addAll(l2);
        return l1;
 });

To sum up, there are several ways to achieve the same as follows:

private <T> List<T> mergeOne(Stream<List<T>> listStream) {
    return listStream.flatMap(List::stream).collect(toList());
}

private <T> List<T> mergeTwo(Stream<List<T>> listStream) {
    List<T> result = new ArrayList<>();
    listStream.forEach(result::addAll);
    return result;
}

private <T> List<T> mergeThree(Stream<List<T>> listStream) {
    return listStream.reduce(new ArrayList<>(), (l1, l2) -> {
        l1.addAll(l2);
        return l1;
    });
}

private <T> List<T> mergeFour(Stream<List<T>> listStream) {
    return listStream.reduce((l1, l2) -> {
        List<T> l = new ArrayList<>(l1);
        l.addAll(l2);
        return l;
    }).orElse(new ArrayList<>());
}

private <T> List<T> mergeFive(Stream<List<T>> listStream) {
    return listStream.collect(ArrayList::new, List::addAll, List::addAll);
}

You can figure out the dimensions of the screen dynamically

Display mDisplay= activity.getWindowManager().getDefaultDisplay();
int width= mDisplay.getWidth();
int Height= mDisplay.getHeight();

The layout can be set using the width and the height obtained using this method.

It really doesn't matter. Just make sure you name your variables and functions descriptively. Also be consistent.

Nowt worse than seeing code like this:

int anInt;                  // Great name for a variable there ...
int myVar = Func( anInt );  // And on this line a great name for a function and myVar
                            // lacks the consistency already, poorly, laid out! 

Edit: As pointed out by my commenter that consistency needs to be maintained across an entire team. As such it doesn't matter WHAT method you chose, as long as that consistency is maintained. There is no right or wrong method, however. Every team I've worked in has had different ideas and I've adapted to those.

Of course you can add jars to that folder. But maybe it does not what you want to achieve...

If you need these jars for compilation, check this related question: Can I add jars to maven 2 build classpath without installing them?

Also, before anyone suggests it, do NOT use the system scope.

My problem was with TIMEZONE in emulator genymotion. Change TIMEZONE ANDROID EMULATOR equal TIMEZONE SERVER, solved problem.

How to insert current time into a timestamp with SQL Server:

In newer versions of SQL Server, timestamp is renamed to RowVersion. Rightly so, because timestamp name is misleading.

SQL Server's timestamp IS NOT set by the user and does not represent a date or a time. Timestamp is only good for making sure a row hasn't changed since it's been read.

If you want to store a date or a time, do not use timestamp, you must use one of the other datatypes, like for example datetime, smalldatetime, date, time or DATETIME2

For example:

create table wtf (
    id INT,
    leet timestamp
)

insert into wtf (id) values (15)

select * from wtf

15    0x00000000000007D3 

'timestamp' in mssql is some kind of internal datatype. Casting that number to datetime produces a nonsense number.

Using jQuery the easiest will be:

var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';

var output = $("<div />").html(text).text();
console.log(output);

Content Hugging and Content Compression Resistence Priorities work for elements which can calculate their size intrinsically depending upon the contents which are coming in.

From Apple docs:

Take the number 123.456789

• As an integer, this number would be 123
• As a fixed point (2), this number would be 123.46 (Assuming you rounded it up)
• As a floating point, this number would be 123.456789

Floating point lets you represent most every number with a great deal of precision. Fixed is less precise, but simpler for the computer..

Does GitHub have this social feature?

If the commit email is kept private, GitHub now (July 2020) proposes:

Users and organizations can now add Twitter usernames to their GitHub profiles

You can now add your Twitter username to your GitHub profile directly from your profile page, via profile settings, and also the REST API.

We've also added the latest changes:

• Organization admins can now add Twitter usernames to their profile via organization profile settings and the REST API.
• All users are now able to see Twitter usernames on user and organization profiles, as well as via the REST and GraphQL APIs.
• When sponsorable maintainers and organizations add Twitter usernames to their profiles, we'll encourage new sponsors to include that Twitter username when they share their sponsorships on Twitter.

That could be a workaround to leave a message to a GitHub user.

By changing a code of Francisco Cabezas, I got the following:

private int selectedRow = -1;

...

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    parent.getChildAt(position).setBackgroundResource(R.color.orange);
    if (selectedRow != -1 && selectedRow != position) {
        parent.getChildAt(selectedRow).setBackgroundResource(R.color.black);
    }
    selectedRow = position;

Ran into this issue with spring boot and jvm 1.7 and 1.8. On AWS, we did not have the option to change the ServerName and ServerAlias to match (they are different) so we did the following:

In build.gradle we added the following:

System.setProperty("jsse.enableSNIExtension", "false")
bootRun.systemProperties = System.properties

That allowed us to bypass the issue with the "Unrecognized Name".

In this answer I am using an example posted by Justin Grammens.

About JSON

JSON stands for JavaScript Object Notation. In JavaScript properties can be referenced both like this object1.name and like this object['name'];. The example from the article uses this bit of JSON.

The Parts
A fan object with email as a key and [email protected] as a value

{
  fan:
    {
      email : '[email protected]'
    }
}

So the object equivalent would be fan.email; or fan['email'];. Both would have the same value of '[email protected]'.

About HttpClient Request

The following is what our author used to make a HttpClient Request. I do not claim to be an expert at all this so if anyone has a better way to word some of the terminology feel free.

public static HttpResponse makeRequest(String path, Map params) throws Exception 
{
    //instantiates httpclient to make request
    DefaultHttpClient httpclient = new DefaultHttpClient();

    //url with the post data
    HttpPost httpost = new HttpPost(path);

    //convert parameters into JSON object
    JSONObject holder = getJsonObjectFromMap(params);

    //passes the results to a string builder/entity
    StringEntity se = new StringEntity(holder.toString());

    //sets the post request as the resulting string
    httpost.setEntity(se);
    //sets a request header so the page receving the request
    //will know what to do with it
    httpost.setHeader("Accept", "application/json");
    httpost.setHeader("Content-type", "application/json");

    //Handles what is returned from the page 
    ResponseHandler responseHandler = new BasicResponseHandler();
    return httpclient.execute(httpost, responseHandler);
}

Map

If you are not familiar with the Map data structure please take a look at the Java Map reference. In short, a map is similar to a dictionary or a hash.

private static JSONObject getJsonObjectFromMap(Map params) throws JSONException {

    //all the passed parameters from the post request
    //iterator used to loop through all the parameters
    //passed in the post request
    Iterator iter = params.entrySet().iterator();

    //Stores JSON
    JSONObject holder = new JSONObject();

    //using the earlier example your first entry would get email
    //and the inner while would get the value which would be '[email protected]' 
    //{ fan: { email : '[email protected]' } }

    //While there is another entry
    while (iter.hasNext()) 
    {
        //gets an entry in the params
        Map.Entry pairs = (Map.Entry)iter.next();

        //creates a key for Map
        String key = (String)pairs.getKey();

        //Create a new map
        Map m = (Map)pairs.getValue();   

        //object for storing Json
        JSONObject data = new JSONObject();

        //gets the value
        Iterator iter2 = m.entrySet().iterator();
        while (iter2.hasNext()) 
        {
            Map.Entry pairs2 = (Map.Entry)iter2.next();
            data.put((String)pairs2.getKey(), (String)pairs2.getValue());
        }

        //puts email and '[email protected]'  together in map
        holder.put(key, data);
    }
    return holder;
}

(I will take down if Justin Grammens does not approve. But if not then thanks Justin for being cool about it.)

Update

I just happend to get a comment about how to use the code and realized that there was a mistake in the return type. The method signature was set to return a string but in this case it wasnt returning anything. I changed the signature to HttpResponse and will refer you to this link on Getting Response Body of HttpResponse the path variable is the url and I updated to fix a mistake in the code.

get the contact number whom you want to send the message and create uri for whatsapp, here c is a Cursor returning the selected contact.

Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

Live demo

first, check its offset every time you scroll the page

$(document).scroll(function() {
    checkOffset();
});

and make its position absolute if it has been downed under 10px before the footer.

function checkOffset() {
    if($('#social-float').offset().top + $('#social-float').height() 
                                           >= $('#footer').offset().top - 10)
        $('#social-float').css('position', 'absolute');
    if($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
        $('#social-float').css('position', 'fixed'); // restore when you scroll up
}

notice that #social-float's parent should be sibling of the footer

<div class="social-float-parent">
    <div id="social-float">
        something...
    </div>
</div>
<div id="footer">
</div>

good luck :)

            return re.test(email);
           }

Or use download attribute to tag in HTML5

If in addition you want to pipe the output to a separate file, you can do:

On a Sun JVM:

-Xloggc:C:\whereever\jvm.log -verbose:gc -XX:+PrintGCDateStamps

ON an IBM JVM:

-Xverbosegclog:C:\whereever\jvm.log 

If you find yourself doing things like this regularly it may be worth investigating the object-oriented interface to matplotlib. In your case:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(5)
y = np.exp(x)
fig1, ax1 = plt.subplots()
ax1.plot(x, y)
ax1.set_title("Axis 1 title")
ax1.set_xlabel("X-label for axis 1")

z = np.sin(x)
fig2, (ax2, ax3) = plt.subplots(nrows=2, ncols=1) # two axes on figure
ax2.plot(x, z)
ax3.plot(x, -z)

w = np.cos(x)
ax1.plot(x, w) # can continue plotting on the first axis

It is a little more verbose but it's much clearer and easier to keep track of, especially with several figures each with multiple subplots.

To avoid any potential confusion, I would like to contrast static variables and immutable objects.

Some primitive object types like integers, floats, strings, and touples are immutable in Python. This means that the object that is referred to by a given name cannot change if it is of one of the aforementioned object types. The name can be reassigned to a different object, but the object itself may not be changed.

Making a variable static takes this a step further by disallowing the variable name to point to any object but that to which it currently points. (Note: this is a general software concept and not specific to Python; please see others' posts for information about implementing statics in Python).

The range of char is 127 to -128. If you assign 212, ch stores -44 (212-128-128) not 212.So if you try to print a negative number as unsigned you get (MAX value of unsigned int)-abs(number) which in this case is 4294967252

So if you want to store 212 as it is in ch the only thing you can do is declare ch as

unsigned char ch;

now the range of ch is 0 to 255.

If you are using the push_back there is no call for the string constructor. Otherwise it will create a string object via casting, then it will add the character in this string to the other string. Too much trouble for a tiny character ;)

As per @Nitsew's answer, Create your personal access token and use your token as your username and enter with blank password.

Later you won't need any credentials to access all your private repo(s).

You are consuming a line at, which is discarded

while((str=input.readLine())!=null && str.length()!=0)

and reading a bigint at

BigInteger n = new BigInteger(input.readLine());

so try getting the bigint from string which is read as

BigInteger n = new BigInteger(str);

   Constructor used: BigInteger(String val)

Aslo change while((str=input.readLine())!=null && str.length()!=0) to

while((str=input.readLine())!=null)

see related post string to bigint

readLine()
Returns:
    A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached 

see javadocs

I looked at the HTML generated by the UI Dialog. It renders buttons pane like this:

<div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
     <button type="button" class="ui-state-default ui-corner-all">Delete all items in recycle bin</button>
     <button type="button" class="ui-state-default ui-corner-all different" style="border: 1px solid blue;">Cancel</button>
</div>

Adding a class to Cancel button should be easy.

$('.ui-dialog-buttonpane :last-child').css('background-color', '#ccc');

This will make the Cancel button little grey. You can style this button however you like.

Above code assumes that the Cancel button is the last button. The fool proof way to do it would be

$('.ui-dialog-buttonpane :button')
    .each(
        function()
        { 
            if($(this).text() == 'Cancel')
            {
                //Do your styling with 'this' object.
            }
        }
    );

Add the following line to the beginning script1.py

#!/usr/bin/env python

and then make the script executable:

$ chmod +x script1.py

If the script resides in a directory that appears in your PATH variable, you can simply type

$ script1.py

Otherwise, you'll need to provide the full path (either absolute or relative). This includes the current working directory, which should not be in your PATH.

$ ./script1.py

This can be done in a single line, as long as the worksheet is active:

ActiveSheet.Visible = xlSheetHidden

However, you may not want to do this, especially if you use any "select" operations or you use any more ActiveSheet operations.

I have been playing about with tmux today, trying to customised a little here and there, managed to get battery info displaying on the status right with a ruby script.

Copy the ruby script from http://natedickson.com/blog/2013/04/30/battery-status-in-tmux/ and save it as:

 battinfo.rb in ~/bin

To make it executable make sure to run:

chmod +x ~/bin/battinfo.rb

edit your ~/.tmux.config and include this line

set -g status-right "#[fg=colour155]#(pmset -g batt | ~/bin/battinfo.rb) | #[fg=colour45]%d %b %R"

try

mat.sum()

If the sum of your data is infinity (greater that the max float value which is 3.402823e+38) you will get that error.

see the _assert_all_finite function in validation.py from the scikit source code:

if is_float and np.isfinite(X.sum()):
    pass
elif is_float:
    msg_err = "Input contains {} or a value too large for {!r}."
    if (allow_nan and np.isinf(X).any() or
            not allow_nan and not np.isfinite(X).all()):
        type_err = 'infinity' if allow_nan else 'NaN, infinity'
        # print(X.sum())
        raise ValueError(msg_err.format(type_err, X.dtype))

Rollback... will prompt you to select a folder to rollback, ie, it will work on specific folders, and you can rollback to labels or changlists or dates. Back out works on the files in specific changelists.

git status | sed 's/^#\s*deleted:\s*//' | sed 's/^#.*//' | xargs git rm -rf

fmt.Sprintf("%v",value);

If you know the specific type of value use the corresponding formatter for example %d for int

Our global AsyncTask class variable

LongOperation LongOperationOdeme = new LongOperation();

And KEYCODE_BACK action which interrupt AsyncTask

   @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            LongOperationOdeme.cancel(true);
        }
        return super.onKeyDown(keyCode, event);
    }

It works for me.

A reliable way to address this is

from six.moves import input

six is a module which patches over many of the 2/3 common code base pain points.

This is based on cfx's solution, but rather than setting the font size to zero in the parent container to remove the inter-column spaces added because of the display: inline-block and having to reset them, I simply added

.row.row-align-bottom > div {_x000D_
    float: none;_x000D_
    display: inline-block;_x000D_
    vertical-align: bottom;_x000D_
    margin-right: -0.25em;_x000D_
}

to the column divs to compensate.

arrayData.forEach((key : any, val: any) => {
                        key['index'] = val + 1;

                        arrayData2.forEach((keys : any, vals :any) => {
                            if (key.group_id == keys.id) {
                                key.group_name = keys.group_name;
                            }
                        })
                    })

git generally requires a non-empty message because providing a meaningful commit message is part of good development practice and good repository stewardship. The first line of the commit message is used all over the place within git; for more, read "A Note About Git Commit Messages".

If you open Terminal.app, cd to your project directory, and git commit -am '', you will see that it fails because an empty commit message is not allowed. Newer versions of git have the
--allow-empty-message commandline argument, including the version of git included with the latest version of Xcode. This will let you use this command to make a commit with an empty message:

git commit -a --allow-empty-message -m ''

Prior to the --allow-empty-message flag, you had to use the commit-tree plumbing command. You can see an example of using this command in the "Raw Git" chapter of the Git book.

Just check in you projects properties >build ->packaging WAR file compress.

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

I have found that wget does not properly authenticate with some servers, perhaps because it is only HTTP 1.0 compliant. In such cases, curl (which is HTTP 1.1 compliant) usually does the trick:

curl -o <filename-to-save-as> -u <username>:<password> <url>

Just to clarify, the reason why there is no member like contains() in these container types is because it would open you up to writing inefficient code. Such a method would probably just do a this->find(key) != this->end() internally, but consider what you do when the key is indeed present; in most cases you'll then want to get the element and do something with it. This means you'd have to do a second find(), which is inefficient. It's better to use find directly, so you can cache your result, like so:

auto it = myContainer.find(key);
if (it != myContainer.end())
{
    // Do something with it, no more lookup needed.
}
else
{
    // Key was not present.
}

Of course, if you don't care about efficiency, you can always roll your own, but in that case you probably shouldn't be using C++... ;)

I'm new to git but it seems that if I do git checkout for each directory then it works. Also, the sparse-checkout file needs to have a trailing slash after every directory as indicated. Someone more experience please confirm that this will work.

Interestingly, if you checkout a directory not in the sparse-checkout file it seems to make no difference. They don't show up in git status and git read-tree -m -u HEAD doesn't cause it to be removed. git reset --hard doesn't cause the directory to be removed either. Anyone more experienced care to comment on what git thinks of directories that are checked out but which are not in the sparse checkout file?

1. Writing JSON Parser Class

   public class JSONParser {
   
       static InputStream is = null;
       static JSONObject jObj = null;
       static String json = "";
   
       // constructor
       public JSONParser() {}
   
       public JSONObject getJSONFromUrl(String url) {
   
           // Making HTTP request
           try {
               // defaultHttpClient
               DefaultHttpClient httpClient = new DefaultHttpClient();
               HttpPost httpPost = new HttpPost(url);
   
               HttpResponse httpResponse = httpClient.execute(httpPost);
               HttpEntity httpEntity = httpResponse.getEntity();
               is = httpEntity.getContent();
   
           } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
           } catch (ClientProtocolException e) {
               e.printStackTrace();
           } catch (IOException e) {
               e.printStackTrace();
           }
   
           try {
               BufferedReader reader = new BufferedReader(new InputStreamReader(
                       is, "iso-8859-1"), 8);
               StringBuilder sb = new StringBuilder();
               String line = null;
               while ((line = reader.readLine()) != null) {
                   sb.append(line + "\n");
               }
               is.close();
               json = sb.toString();
           } catch (Exception e) {
               Log.e("Buffer Error", "Error converting result " + e.toString());
           }
   
           // try parse the string to a JSON object
           try {
               jObj = new JSONObject(json);
           } catch (JSONException e) {
               Log.e("JSON Parser", "Error parsing data " + e.toString());
           }
   
           // return JSON String
           return jObj;
   
       }
   }
   

2. Parsing JSON Data
   Once you created parser class next thing is to know how to use that class. Below i am explaining how to parse the json (taken in this example) using the parser class.

   2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.

   // url to make request
   private static String url = "http://api.9android.net/contacts";
   
   // JSON Node names
   private static final String TAG_CONTACTS = "contacts";
   private static final String TAG_ID = "id";
   private static final String TAG_NAME = "name";
   private static final String TAG_EMAIL = "email";
   private static final String TAG_ADDRESS = "address";
   private static final String TAG_GENDER = "gender";
   private static final String TAG_PHONE = "phone";
   private static final String TAG_PHONE_MOBILE = "mobile";
   private static final String TAG_PHONE_HOME = "home";
   private static final String TAG_PHONE_OFFICE = "office";
   
   // contacts JSONArray
   JSONArray contacts = null;
   

   2.2. Use parser class to get JSONObject and looping through each json item. Below i am creating an instance of JSONParser class and using for loop i am looping through each json item and finally storing each json data in variable.

   // Creating JSON Parser instance
   JSONParser jParser = new JSONParser();
   
   // getting JSON string from URL
   JSONObject json = jParser.getJSONFromUrl(url);
   
       try {
       // Getting Array of Contacts
       contacts = json.getJSONArray(TAG_CONTACTS);
   
       // looping through All Contacts
       for(int i = 0; i < contacts.length(); i++){
           JSONObject c = contacts.getJSONObject(i);
   
           // Storing each json item in variable
           String id = c.getString(TAG_ID);
           String name = c.getString(TAG_NAME);
           String email = c.getString(TAG_EMAIL);
           String address = c.getString(TAG_ADDRESS);
           String gender = c.getString(TAG_GENDER);
   
           // Phone number is agin JSON Object
           JSONObject phone = c.getJSONObject(TAG_PHONE);
           String mobile = phone.getString(TAG_PHONE_MOBILE);
           String home = phone.getString(TAG_PHONE_HOME);
           String office = phone.getString(TAG_PHONE_OFFICE);
   
       }
   } catch (JSONException e) {
       e.printStackTrace();
   }
   

I think a combination of xdg-open as described by shellholic and - if it fails - the solution to finding a browser using the which command as described here is probably the best solution.

One who has tried all other answers and had no luck the please check this check box, hope it'll help (did the trick for me xcode 6.0.1)

In my instance, I was running an abnormal query to fix data. If you lock the tables in your query, then you won't have to deal with the Lock timeout:

LOCK TABLES `customer` WRITE;
update customer set account_import_id = 1;
UNLOCK TABLES;

This is probably not a good idea for normal use.

For more info see: MySQL 8.0 Reference Manual

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

src should be in quotes:

$('.img1 img').attr('src');

in mvc 5

              @Html.EditorFor(x => x.Address, 
              new {htmlAttributes = new {@class = "form-control", 
                   @placeholder = "Complete Address", @cols = 10, @rows = 10 } })

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

Inserting Space in emailId field after every 8 characters

public string BreakEmailId(string emailId) {
    string returnVal = string.Empty;
    if (emailId.Length > 8) {           
        for (int i = 0; i < emailId.Length; i += 8) {
            returnVal += emailId.Substring(i, 8) + " ";
        }
    }

    return returnVal;
}

You may get the following error while creating an optimized production build when using query-string module.

Failed to minify the code from this file: ./node_modules/query-string/index.js:8

To overcome this, kindly use the alternative module called stringquery which does the same process well without any issues while running the build.

import querySearch from "stringquery";

var query = querySearch(this.props.location.search);

I was having some trouble with this, and the "X:not():not()" method wasn't working for me.

I ended up resorting to this strategy:

INPUT {
    /* styles */
}
INPUT[type="radio"], INPUT[type="checkbox"] {
    /* styles that reset previous styles */
}

It's not nearly as fun, but it worked for me when :not() was being pugnacious. It's not ideal, but it's solid.

1. We need Git Bash
2. In Git Bash Command Section::

1.1 ls

It will show you default location.

1.2 CD "C:\Users\user\Desktop\HTML" We need to assign project path

1.3 git init It will initialize the empty git repository in C:\Users\user\Desktop\HTML

1.4 ls It will list all files name

1.5 git remote add origin https://github.com/repository/test.git it is your https://github.com/repository/test.git is your repository path

1.6 git remote -v To check weather we have fetch or push permisson or not

1.7 git add . If you put . then it mean whatever we have in perticular folder publish all.

1.8 git commit -m "First time"

1.9 git push -u origin master

Nope! You have to do it at runtime.

If you want to make your app backwards compatible, then simply check the device API level. If it is higher than 11, then you can fiddle with the ActionBar and set the subtitle.

if(Integer.valueOf(android.os.Build.VERSION.SDK) >= 11){
    //set actionbar title
}

ES5 Object.keys

var a = { a: 1, b: 2, c: 3 };
Object.keys(a).map(function(key){ return a[key] });
// result: [1,2,3]

A lot of answers already but in the hope that this helps someone. This is an issue that occurs when you install docker via snap. Running via sudo would allow you to connect to the daemon, but this leads to other issues. The solution is to perform some steps BEFORE you install the snap package making the complete list of steps:

sudo addgroup --system docker
sudo adduser $USER docker
newgrp docker
sudo snap install docker

After doing this, docker will connect to the daemon and work without sudo, no restart required.

The class BooleanUtils supportes the negation of a boolean. You find this class in commons-lang:commons-lang

BooleanUtils.negate(theBoolean)

Try using the COLUMN command with the FORMAT option for that:

COLUMN COLUMN_NAME FORMAT 99.99
SELECT COLUMN_NAME FROM ....

You can use background-size: cover;

Try this instead, remove the SelectCommand property and SelectParameters:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:itematConnectionString %>">

Then in the code behind do this:

SqlDataSource1.SelectParameters.Add("userId", userId.ToString());

SqlDataSource1.SelectCommand = "SELECT items.name, items.id FROM items INNER JOIN users_items ON items.id = users_items.id WHERE (users_items.user_id = @userId) ORDER BY users_items.date DESC"

While this worked for me, the following code also works:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:itematConnectionString %>"
    SelectCommand = "SELECT items.name, items.id FROM items INNER JOIN users_items ON items.id = users_items.id WHERE (users_items.user_id = @userId) ORDER BY users_items.date DESC"></asp:SqlDataSource>


SqlDataSource1.SelectParameters.Add("userid", DbType.Guid, userId.ToString());

use

<div class="btn-group btn-group-justified">
  ...
</div>

but it only works for <a> elements and not <button> elements.

No posters have mentioned the contraction of floating expressions yet (ISO C standard, 6.5p8 and 7.12.2). If the FP_CONTRACT pragma is set to ON, the compiler is allowed to regard an expression such as a*a*a*a*a*a as a single operation, as if evaluated exactly with a single rounding. For instance, a compiler may replace it by an internal power function that is both faster and more accurate. This is particularly interesting as the behavior is partly controlled by the programmer directly in the source code, while compiler options provided by the end user may sometimes be used incorrectly.

The default state of the FP_CONTRACT pragma is implementation-defined, so that a compiler is allowed to do such optimizations by default. Thus portable code that needs to strictly follow the IEEE 754 rules should explicitly set it to OFF.

If a compiler doesn't support this pragma, it must be conservative by avoiding any such optimization, in case the developer has chosen to set it to OFF.

GCC doesn't support this pragma, but with the default options, it assumes it to be ON; thus for targets with a hardware FMA, if one wants to prevent the transformation a*b+c to fma(a,b,c), one needs to provide an option such as -ffp-contract=off (to explicitly set the pragma to OFF) or -std=c99 (to tell GCC to conform to some C standard version, here C99, thus follow the above paragraph). In the past, the latter option was not preventing the transformation, meaning that GCC was not conforming on this point: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=37845

In case if you want to implement your own Array.Copy method.

Static method which is of generic type.

 static void MyCopy<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long destinationIndex, long copyNoOfElements)
 {
  long totaltraversal = sourceIndex + copyNoOfElements;
  long sourceArrayLength = sourceArray.Length;

  //to check all array's length and its indices properties before copying
  CheckBoundaries(sourceArray, sourceIndex, destinationArray, copyNoOfElements, sourceArrayLength);
   for (long i = sourceIndex; i < totaltraversal; i++)
     {
      destinationArray[destinationIndex++] = sourceArray[i]; 
     } 
  }

Boundary method implementation.

private static void CheckBoundaries<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long copyNoOfElements, long sourceArrayLength)
        {
            if (sourceIndex >= sourceArray.Length)
            {
                throw new IndexOutOfRangeException();
            }
            if (copyNoOfElements > sourceArrayLength)
            {
                throw new IndexOutOfRangeException();
            }
            if (destinationArray.Length < copyNoOfElements)
            {
                throw new IndexOutOfRangeException();
            }
        }

@JAB's answer is fast and concise. But it changes the DataFrame you are trying to sort, which you may or may not want.

_{(Note: You almost certainly will want it, because your date columns should be dates, not strings!)}

In the unlikely event that you don't want to change the dates into dates, you can also do it a different way.

First, get the index from your sorted Date column:

In [25]: pd.to_datetime(df.Date).order().index
Out[25]: Int64Index([0, 2, 1], dtype='int64')

Then use it to index your original DataFrame, leaving it untouched:

In [26]: df.ix[pd.to_datetime(df.Date).order().index]
Out[26]: 
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

Magic!

Note: for Pandas versions 0.20.0 and later, use loc instead of ix, which is now deprecated.

If all you are trying to do is capture the output from a command, then this will work well.

I use it for changing system time, as [timezoneinfo]::local always produces the same information, even after you have made changes to the system. This is the only way I can validate and log the change in time zone:

$NewTime = (powershell.exe -command [timezoneinfo]::local)
$NewTime | Tee-Object -FilePath $strLFpath\$strLFName -Append

Meaning that I have to open a new PowerShell session to reload the system variables.

While you can execute backup commands from PHP, they don't really have anything to do with PHP. It's all about MySQL.

I'd suggest using the mysqldump utility to back up your database. The documentation can be found here : http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html.

The basic usage of mysqldump is

mysqldump -u user_name -p name-of-database >file_to_write_to.sql

You can then restore the backup with a command like

mysql -u user_name -p <file_to_read_from.sql

Do you have access to cron? I'd suggest making a PHP script that runs mysqldump as a cron job. That would be something like

<?php

$filename='database_backup_'.date('G_a_m_d_y').'.sql';

$result=exec('mysqldump database_name --password=your_pass --user=root --single-transaction >/var/backups/'.$filename,$output);

if(empty($output)){/* no output is good */}
else {/* we have something to log the output here*/}

If mysqldump is not available, the article describes another method, using the SELECT INTO OUTFILE and LOAD DATA INFILE commands. The only connection to PHP is that you're using PHP to connect to the database and execute the SQL commands. You could also do this from the command line MySQL program, the MySQL monitor.

It's pretty simple, you're writing an SQL file with one command, and loading/executing it when it's time to restore.

You can find the docs for select into outfile here (just search the page for outfile). LOAD DATA INFILE is essentially the reverse of this. See here for the docs.

This works for me:

FROM postgres:9.6
USER postgres

# Copy postgres config file into container
COPY postgresql.conf /etc/postgresql

# Override default postgres config file
CMD ["postgres", "-c", "config_file=/etc/postgresql/postgresql.conf"]

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

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

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

FileReader won't let you specify the encoding, use InputStreamReaderinstead if you need to specify it:

try {
    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), "Cp1252"));         

    String line;
    while ((line = br.readLine()) != null) {
        // process the line.
    }
    br.close();

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

If you imported this file from Windows, it might have ANSI encoding (Cp1252), so you have to specify the encoding.

By the way, if you need to add other characters such as "(" or ")" because the column may be used as "UPPER(bqr)", then those options can be added to the lists of before and after characters.

(\s|\(|\.|,|^)bqr(\s|,|\)|$)

1. update - modify existent only. To avoid side effect of indexer use:

   int val;
   if (dic.TryGetValue(key, out val))
   {
       // key exist
       dic[key] = val;
   }
   

2. update or (add new if value doesn't exist in dic)

   dic[key] = val;
   

   for instance:

   d["Two"] = 2; // adds to dictionary because "two" not already present
   d["Two"] = 22; // updates dictionary because "two" is now present
   

Maybe this code helps:

var chunk_size = 10;_x000D_
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];_x000D_
var groups = arr.map( function(e,i){ _x000D_
     return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null; _x000D_
}).filter(function(e){ return e; });_x000D_
console.log({arr, groups})

Here is another way without using additional libraries (no error checking included)

function saveAll( callback ){
  var count = 0;
  docs.forEach(function(doc){
      doc.save(function(err){
          count++;
          if( count == docs.length ){
             callback();
          }
      });
  });
}

I have just faced this problem, and the solution is that the property "mail.smtp.user" should be your email (not username).

The example for gmail user:

properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.user", from);
properties.put("mail.smtp.password", pass);
properties.put("mail.smtp.port", "587");
properties.put("mail.smtp.auth", "true");

If you're not just looking for books, but also interested in web sites that have articles on the topic, I've blogged about various aspects of creating a programming language. Most of the posts can be found in my blog's "Language Design" category.

In particular, I cover generating Intel machine code manually, automatically generating machine- or bytecode, creating a bytecode interpreter, writing an object-oriented runtime, creating a simple loader, and writing a simple mark/sweep garbage collector. All of this in a very practical and pragmatic way instead of boring you with lots of theory.

Would appreciate feedback on these.

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

Since function pointers are often typed callbacks, you might want to have a look at type safe callbacks. The same applies to entry points, etc of functions that are not callbacks.

C is quite fickle and forgiving at the same time :)

I've been a Vim user for years. I'm starting to find myself starting up Eclipse occasionally (using the vi plugin, which, I have to say, has a variety of issues). The main reason is that Java builds take quite a while...and they are just getting slower and slower with the addition of highly componentized build-frameworks like maven. So validating your changes tends to take quite a while, which for me seems to often lead to stacking up a bunch of compile issues I have to resolve later, and filtering through the commit messages takes a while.

When I get too big of a queue of compile issues, I fire up Eclipse. It lets me make cake-work of the changes. It's slow, brutal to use, and not nearly as nice of an editor as Vim is (I've been using Vim for nearly a decade, so it's second nature to me). I find for precision editing—needing to fix a specific bug, needing to refactor some specific bit of logic, or something else...I simply can't be as efficient at editing in Eclipse as I can in Vim.

Also a tip:

:set path=**
:chdir your/project/root

This makes ^wf on a classname a very nice feature for navigating a large project.

So anyway, the skinny is, when I need to add a lot of new code, Vim seems to slow me down simply due to the time spent chasing down compilation issues and similar stuff. When I need to find and edit specific sources, though, Eclipse feels like a sledge hammer. I'm still waiting for the magical IDE for Vim. There's been three major attempts I know of. There's a pure viml IDE-type plugin which adds a lot of features but seems impossible to use. There's eclim, which I've had a lot of trouble with. And there's a plugin for Eclipse which actually embeds Vim. The last one seems the most promising for real serious Java EE work, but it doesn't seem to work very well or really integrate all of Eclipse's features with the embedded Vim.

Things like add a missing import with a keystroke, hilight code with typing issues, etc, seems to be invaluable from your IDE when working on a large Java project.

Well id isn't really the root node: Login is.

It should just be a case of specifying the attributes (not tags, btw) using XmlElement.SetAttribute. You haven't specified how you're creating the file though - whether you're using XmlWriter, the DOM, or any other XML API.

If you could give an example of the code you've got which isn't working, that would help a lot. In the meantime, here's some code which creates the file you described:

using System;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement root = doc.CreateElement("Login");
        XmlElement id = doc.CreateElement("id");
        id.SetAttribute("userName", "Tushar");
        id.SetAttribute("passWord", "Tushar");
        XmlElement name = doc.CreateElement("Name");
        name.InnerText = "Tushar";
        XmlElement age = doc.CreateElement("Age");
        age.InnerText = "24";

        id.AppendChild(name);
        id.AppendChild(age);
        root.AppendChild(id);
        doc.AppendChild(root);

        doc.Save("test.xml");
    }
}

You can create a trigger which updates NoofUses column in Coupon table whenever couponid is used in CouponUse table

query :

CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
  BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end 

Make sure that each Application Pool in IIS, under Advanced Settings has Enable 32 bit Applications set to True

If you use the callback URL, then the API can connect to the callback URL and send or receive some data. That means API can connect to you later (after API call).

Example

1. YOU send data using request to API
2. API sends data using second request to YOU

Exact definition should be in API documentation.

Try:

 DateTime.TryParseExact(txtStartDate.Text, formats, 
        System.Globalization.CultureInfo.InvariantCulture,
        System.Globalization.DateTimeStyles.None, out startDate)

Just use UniversalImageLoader and set

DisplayImageOptions.Builder()
    .imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
    .build();

and no scale settings on ImageView

If you want to open multiple workspaces and you are not a terminal guy, just locate the Unix executable file in your eclipse folder and click it.

The path to the said file is

Eclipse(folder) -> eclipse(right click) -> Show package Contents -> Contents -> MacOs -> eclipse(unix executable file)

Clicking on this executable will open a separate instance of eclipse.

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

Here are some simple techniques for vertical-align:

One-line vertical-align:middle

This one is easy: set the line-height of the text element to equal that of the container

<div>
  <img style="width:30px; height:30px;">
  <span style="line-height:30px;">Doesn't work.</span>
</div>

Multiple-lines vertical-align:bottom

Absolutely position an inner div relative to its container

<div style="position:relative;width:30px;height:60px;">
  <div style="position:absolute;bottom:0">This is positioned on the bottom</div>
</div>

Multiple-lines vertical-align:middle

<div style="display:table;width:30px;height:60px;">
  <div style="display:table-cell;height:30px;">This is positioned in the middle</div>
</div>

If you must support ancient versions of IE <= 7

In order to get this to work correctly across the board, you'll have to hack the CSS a bit. Luckily, there is an IE bug that works in our favor. Setting top:50% on the container and top:-50% on the inner div, you can achieve the same result. We can combine the two using another feature IE doesn't support: advanced CSS selectors.

<style type="text/css">
  #container {
    width: 30px;
    height: 60px;
    position: relative;
  }
  #wrapper > #container {
    display: table;
    position: static;
  }
  #container div {
    position: absolute;
    top: 50%;
  }
  #container div div {
    position: relative;
    top: -50%;
  }
  #container > div {
    display: table-cell;
    vertical-align: middle;
    position: static;
  }
</style>

<div id="wrapper">
  <div id="container">
    <div><div><p>Works in everything!</p></div></div>
  </div>
</div>

Variable container height vertical-align:middle

This solution requires a slightly more modern browser than the other solutions, as it makes use of the transform: translateY property. (http://caniuse.com/#feat=transforms2d)

Applying the following 3 lines of CSS to an element will vertically centre it within its parent regardless of the height of the parent element:

position: relative;
top: 50%;
transform: translateY(-50%);

Try this:

HTML:

<div id="container">
    <div id="content">
        // Content here
    </div>
</div>

CSS:

#container{
    height: 100%;
    width: 100%;
    overflow: hidden;
}

#content{
    width: 100%;
    height: 99%;
    overflow: auto;
    padding-right: 15px;
}

html, body{
    height: 99%;
    overflow:hidden;
}
