Yes, below is a link of docs.Oracle where you can find complete list of escape characters in Java.

Escape characters are always preceded with "\" and used to perform some specific task like go to next line etc.

For more Details on Escape Character Refer following link:

Short answer: you can't. Use MSIEXEC /x

Long answer: When you run the MSI file directly at the command line, all that's happening is that it runs MSIEXEC for you. This association is stored in the registry. You can see a list of associations by (in Windows Explorer) going to Tools / Folder Options / File Types.

For example, you can run a .DOC file from the command line, and WordPad or WinWord will open it for you.

If you look in the registry under HKEY_CLASSES_ROOT\.msi, you'll see that .MSI files are associated with the ProgID "Msi.Package". If you look in HKEY_CLASSES_ROOT\Msi.Package\shell\Open\command, you'll see the command line that Windows actually uses when you "run" a .MSI file.

You might also consider trying one of these approaches, since larger tables aren't exactly friendly on mobile even if it works:

http://elvery.net/demo/responsive-tables/

I'm partial to 'No More Tables' but that obviously depends on your application.

you can use:

adb shell su -c "your command here"

only rooted devices with su works.

I think you could use the following HTML and CSS combo instead:

<li>
  <a href="#">Backback</a>
</li>

Then use CSS background for the basket visibility on hover:

.listblock ul li a {
    padding: 5px 30px 5px 10px;
    display: block;
}

.listblock ul li a:hover {
    background: transparent url('../img/basket.png') no-repeat 3px 170px;
}

Simples!

In addition to the answers above, you could encounter this error if your client is running the wrong TLS version, for example if the server is only running TLS 1.2.

You can fix it by using:

// tested in .NET 4.5:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

This method sucks, but I've left it here for reference so others avoid this path:

Using Option 1 from @ninjagecko worked best for me:

Array.prototype.equals = function(array) {
    return array instanceof Array && JSON.stringify(this) === JSON.stringify(array) ;
}

a = [1, [2, 3]]
a.equals([[1, 2], 3]) // false
a.equals([1, [2, 3]]) // true

It will also handle the null and undefined case, since we're adding this to the prototype of array and checking that the other argument is also an array.

It's Unicode.

Just put the variable between str(), and it will work fine.

But in case you have two lists like the following:

a = ['co32','co36']
b = [u'co32',u'co36']

If you check set(a)==set(b), it will come as False, but if you do as follows:

b = str(b)
set(a)==set(b)

Now, the result will be True.

request.data will be empty if request.headers["Content-Type"] is recognized as form data, which will be parsed into request.form. To get the raw data regardless of content type, use request.get_data().

request.data calls request.get_data(parse_form_data=True), which results in the different behavior for form data.

In Spring applications, if you enable annotation based transaction support using <tx:annotation-driven/> and annotate any class/method with @Transactional(propagation=Propagation.REQUIRED) then Spring framework will start a transaction and executes the method and commits the transaction. If any RuntimeException occurred then the transaction will be rolled back.

Actually propagation=Propagation.REQUIRED is default propagation level, you don't need to explicitly mentioned it.

http://www.blackdogfoundry.com/blog/moving-repository-from-bitbucket-to-github/

This helped me move from one git provider to another. At the end of it, all the commits were in the destination git. Simple and straight forward.

git remote rename origin bitbucket
git remote add origin https://github.com/edwardaux/Pipelines.git
git push origin master

Once I was happy that the push had been successful to GitHub, I could delete the old remote by issuing:

git remote rm bitbucket

git log origin/master..master

or, more generally:

git log <since>..<until>

You can use this with grep to check for a specific, known commit:

git log <since>..<until> | grep <commit-hash>

Or you can also use git-rev-list to search for a specific commit:

git rev-list origin/master | grep <commit-hash>

The answer is for the problem:

Exception in thread "main" java.lang.UnsupportedClassVersionError: edu/stevens/cs549/dhts/main/LocalContext : Unsupported major.minor version 52.0

I was having the same problem. For those who were having this trouble in AWS ec2 instances, and have somehow got redirected here to this question. I am answering for those, and would like to share that how I did it. I was having the trouble because Amazon EC2 instances were running java version 1.7 and maybe my project was not compatible with it because I was using Maven and it kind of preconfigured for java 1.8. So I installed new version of java:

sudo yum -y install java-1.8.0

And then the important step is to remove the older version:

sudo yum remove java-1.7.0-openjdk

Remember to delete it after installing the new version, else it would continuously be using the same older version and I hope it resolves your problem, which did in my case.

Since you're not actually changing the filename, you can take out the filename from the destination and there will be no questions.

xcopy bin\development\whee.config.example TestConnectionExternal\bin\Debug\  /Y

This approach works well when the destination directory is guaranteed to exist, and when the source may equally be a file or directory.

Convert to cvs then upload to a version control system then diff with an advanced version control diff tool. When I used perforce it had a great diff tool, but I forget the name of it.

def partition(pred, iterable):
    'Use a predicate to partition entries into false entries and true entries'
    # partition(is_odd, range(10)) --> 0 2 4 6 8   and  1 3 5 7 9
    t1, t2 = tee(iterable)
    return filterfalse(pred, t1), filter(pred, t2)

Check this

You can use OLDand NEW in the trigger to access those values which had changed in that trigger. Mysql Ref

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

I was not able to get the createReadStream/createWriteStream method working for some reason, but using the fs-extra npm module it worked right away. I am not sure of the performance difference though.

npm install --save fs-extra

var fs = require('fs-extra');

fs.copySync(path.resolve(__dirname, './init/xxx.json'), 'xxx.json');

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

You can pass a name to the unknown key and then write your types:

type StuffBody = {
  [key: string]: string;
};

Now you can use it in your type checking:

let stuff: StuffBody = {};

But for FlowType there is no need to have name:

type StuffBody = {
  [string]: string,
};

I know that we are (n-1) * (n times), but why the division by 2?

It's only (n - 1) * n if you use a naive bubblesort. You can get a significant savings if you notice the following:

• After each compare-and-swap, the largest element you've encountered will be in the last spot you were at.

• After the first pass, the largest element will be in the last position; after the k^th pass, the k^th largest element will be in the k^th last position.

Thus you don't have to sort the whole thing every time: you only need to sort n - 2 elements the second time through, n - 3 elements the third time, and so on. That means that the total number of compare/swaps you have to do is (n - 1) + (n - 2) + .... This is an arithmetic series, and the equation for the total number of times is (n - 1)*n / 2.

Example: if the size of the list is N = 5, then you do 4 + 3 + 2 + 1 = 10 swaps -- and notice that 10 is the same as 4 * 5 / 2.

here is my tricky solution how to hide EVERYTHING

1. Before you start you should realize that all youtube's info are sticks to the top and bottom of iframe(not video, that's important)

2. Make iframe higher than real video height. In iframe parameters set height = width * 1.7 (or other multiplicator)

3. Hide youtube's info under your header and footer with an absolute position at top and bottom of iframe wrapper element. Height of header and footer could be calculated as: iframeHeight - (iframeWidth * (9 / 16))) / 2. If you want fullscreen than you should hide it outside screen visible zone and set overflow to hidden

4. In my case I use JS to destroy iframe after video is finished so user couldn't see youtube's offer with another videos

5. Also important note: since iOS 12.2 is replacing Youtube's player by their own, width and height calculation should be done in constructor(in case of React) because iOS player arrival cause page resize ->possible width&height recalculation-> video rerender -> video pause

A disadvantage of this solution is that it stretches image placeholder.

that's how it could look like with custom controls

was implemented that in service-now platform. No need to use other library - makepdf have all you need!

that my html part (include preloder gif):

   <div class="pdf-preview" ng-init="generatePDF(true)">
    <object data="{{c.content}}" type="application/pdf" style="width:58vh;height:88vh;" ng-if="c.content" ></object>
    <div ng-if="!c.content">
      <img src="https://support.lenovo.com/esv4/images/loading.gif" width="50" height="50">
    </div>
  </div>

this is client script (js part)

$scope.generatePDF = function (preview) {
    docDefinition = {} //you rootine to generate pdf content
    //...
    if (preview) {
        pdfMake.createPdf(docDefinition).getDataUrl(function(dataURL) {
            c.content = dataURL;
        });
    }
}

So on page load I fire init function that generate pdf content and if required preview (set as true) result will be assigned to c.content variable. On html side object will be not shown until c.content will got a value, so that will show loading gif.

This doesn't work too well when you have the plugin placed in a thin column, like a sidebar for example. On medium sized screens these typically run smaller than 280px in width.

.fb-page, 
.fb-page span, 
.fb-page span iframe[style] { 
    width: 100% !important; 
}

This is the code I use to stop the plugin breaking outside of a wrapping container. Unlike the old like box which would tile, this one just overflows, hiding the overflowed content.

You can try it like this

  Calendar c= Calendar.getInstance();

  SimpleDateFormat sdf= new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");
  String str=sdf.format(c.getTime());

you can use the following from the device console: pm disable com.my.app.package which will kill it. Then use pm enable com.my.app.package so that you can launch it again.

There's a similar post here: http://techpad.co.uk/content.php?sid=137 which explains how to do it.

function file_get_contents_proxy($url,$proxy){

    // Create context stream
    $context_array = array('http'=>array('proxy'=>$proxy,'request_fulluri'=>true));
    $context = stream_context_create($context_array);

    // Use context stream with file_get_contents
    $data = file_get_contents($url,false,$context);

    // Return data via proxy
    return $data;

}

typeof condition is used to check variable type, if you are check variable type in if-else condition e.g.

if(typeof Varaible_Name "undefined")
{

}

The notion of multi-module projects is there to service the needs of codependent segments of a project. Such a client depends on the services which in turn depends on say EJBs or data-access routines. You could group your continuous integration (CI) tests in this manner. I would rationalize that by saying that the CI tests need to be in lock-step with application logic changes.

Suppose your project is structured as:

project-root
  |
  + --- ci
  |
  + --- client
  |
  + --- server

The project-root/pom.xml defines modules

<modules>
  <module>ci</module>
  <module>client</module>
  <module>server</module>
</modules>

The ci/pom.xml defines profiles such as:

... 
<profiles>
  <profile>
    <id>default</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <plugin>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
         <skip>true</skip>
       </configuration>
     </plugin>
  </profile>
  <profile>
    <id>CI</id>
    <plugin>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
         <skip>false</skip>
       </configuration>
     </plugin>
  </profile>
</profiles>

This will result in Maven skipping tests in this module except when the profile named CI is active. Your CI server must be instructed to execute mvn clean package -P CI. The Maven web site has an in-depth explanation of the profiling mechanism.

This is what I found out in the documentation.

• I : send the file inline to the browser (default). The plug-in is used if available. The name given by name is used when one selects the "Save as" option on the link generating the PDF.
• D : send to the browser and force a file download with the name given by name.
• F : save to a local server file with the name given by name.
• S : return the document as a string (name is ignored).
• FI : equivalent to F + I option
• FD : equivalent to F + D option
• E : return the document as base64 mime multi-part email attachment (RFC 2045)

Here is a way to do it that works, but may not be best practise for any language really:

var x,y;
x='something';
y=1;
undefined === y || (x = y);

alternatively

undefined !== y && (x = y);

Will be there any difference if I use "x" instead of "this.x" in some of the methods?

Usually not. But it makes a difference sometimes:

  class A {
     private int i;
     public A(int i) {
        this.i = i; // this.i can be used to disambiguate the i being referred to
     }
  }

If I just use "method()", will it not be, by default, applied to the current object?

Yes. But if needed, this.method() clarifies that the call is made by this object.

After finding this StackOverflow question/answer

Complex type is getting null in a ApiController parameter

the [FromBody] attribute on the controller method needs to be [FromUri] since a GET does not have a body. After this change the "filter" complex object is passed correctly.

Again if you don't want to use bodyParser, the following works:

var express = require('express');
var http = require('http');
var app = express();

app.use(express.static('./public'));


app.configure(function(){
    app.use(express.methodOverride());
    app.use(express.multipart({
        uploadDir: './uploads',
        keepExtensions: true
    }));
});


app.use(app.router);

app.get('/upload', function(req, res){
    // Render page with upload form
    res.render('upload');
});

app.post('/upload', function(req, res){
    // Returns json of uploaded file
    res.json(req.files);
});

http.createServer(app).listen(3000, function() {
    console.log('App started');
});

You can do it with an confirm() message using Javascript.

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

Besides grep, you can also use other utilities such as awk or sed

Here is a few examples. Let say you want to search for a string is in the file named GPL.

Your sample file

user@linux:~$ cat -n GPL 
     1    The GNU General Public License is a free, copyleft license for
     2    The licenses for most software and other practical works are designed
     3  the GNU General Public License is intended to guarantee your freedom to
     4  GNU General Public License for most of our software;
user@linux:~$ 

1. grep

user@linux:~$ grep is GPL 
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

2. awk

user@linux:~$ awk /is/ GPL 
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

3. sed

user@linux:~$ sed -n '/is/p' GPL
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

Hope this helps

I found two main problems with that implementation. First, when you import the vue.js script you use type="JavaScript" as content-type which is wrong. You should remove this type parameter because by default script tags have text/javascript as default content-type. Or, just replace the type parameter with the correct content-type which is type="text/javascript".

The second problem is that your script is embedded in the same HTML file means that it may be triggered first and probably the vue.js file was not loaded yet. You can fix this using a jQuery snippet $(function(){ /* ... */ }); or adding a javascript function as shown in this example:

// Verifies if the document is ready_x000D_
function ready(f) {_x000D_
  /in/.test(document.readyState) ? setTimeout('ready(' + f + ')', 9) : f();_x000D_
}_x000D_
_x000D_
ready(function() {_x000D_
  var demo = new Vue({_x000D_
    el: '#demo',_x000D_
    data: {_x000D_
      message: 'Hello Vue.js!'_x000D_
    }_x000D_
  })_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>_x000D_

Thought of writing this answer as nothing worked from above & you don't want to specify proxy location.

If you're using httpClient then consider this.

HttpClientHandler handler = new HttpClientHandler();

IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
handler.Proxy = proxy;

var client = new HttpClient(handler);
// your next steps...

And if you're using HttpWebRequest:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri + _endpoint);

IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
request.Proxy = proxy;

Just thought I'd share my hacky solution with anyone who's discovering this problem now with embedded links within a string. It attempts to inline the links by rendering it dynamically with what ever string is fed into it.

Please feel free to tweak it to your needs. It's working for our purposes as such:

"origin/master" refers to the reference poiting to the HEAD commit of branch "origin/master". A reference is a human-friendly alias name to a Git object, typically a commit object. "origin/master" reference only gets updated when you git push to your remote (http://git-scm.com/book/en/v2/Git-Internals-Git-References#Remotes).

From within the root of your project, run:

cat .git/refs/remotes/origin/master

Compare the displayed commit ID with:

cat .git/refs/heads/master

They should be the same, and that's why Git says master is up-to-date with origin/master.

When you run

git fetch origin master

That retrieves new Git objects locally under .git/objects folder. And Git updates .git/FETCH_HEAD so that now, it points to the latest commit of the fetched branch.

So to see the differences between your current local branch, and the branch fetched from upstream, you can run

git diff HEAD FETCH_HEAD

I needed to make a ListView with items of different colors. I modified Shardul's method a bit and result in this:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                this, android.R.layout.simple_list_item_1, colorString) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                TextView textView = (TextView) super.getView(position, convertView, parent);
                textView.setBackgroundColor(assignBackgroundColor(position));
                textView.setTextColor(assignTextColor(position));
                return textView;
            }
        };
        colorList.setAdapter(adapter);

assignBackgroundColor() and assignTextColor() are methods that assign color you want. They can be replaced with int[] arrays.

You can actualy fake the transparency of option DOMElements with the following CSS:

CSS

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

See Demo

The option tag does not support rgba colors yet.

If you want to get client key from request header, u can try following:

In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :

ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt

Just click on the link written in the error:

Open Android SDK Manager

and it will show you the dialogs that will help you to install the required sdk for your project.

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

Assuming this is what the HTML looks like

<div class="form-group required">
   <label class="col-md-2 control-label">E-mail</label>
   <div class="col-md-4"><input class="form-control" id="id_email" name="email" placeholder="E-mail" required="required" title="" type="email" /></div>
</div>

To display an asterisk on the right of the label:

.form-group.required .control-label:after { 
    color: #d00;
    content: "*";
    position: absolute;
    margin-left: 8px;
    top:7px;
}

Or to the left of the label:

.form-group.required .control-label:before{
   color: red;
   content: "*";
   position: absolute;
   margin-left: -15px;
}

To make a nice big red asterisks you can add these lines:

font-family: 'Glyphicons Halflings';
font-weight: normal;
font-size: 14px;

Or if you are using Font Awesome add these lines (and change the content line):

font-family: 'FontAwesome';
font-weight: normal;
font-size: 14px;
content: "\f069";

Best and easiest way is to use anchor tag in CodeIgniter like eg.

<?php 
    $this->load->helper('url'); 
    echo anchor('name_of_controller_file/function_name_if_any', 'Sign Out', array('class' => '', 'id' => '')); 
?>

Refer https://www.codeigniter.com/user_guide/helpers/url_helper.html for details

This will surely work.

None of the above worked for me in the current youtube embed. Try this, it actually worked for me :)

Hope it helps!

It's pretty simple really:

a[start:stop]  # items start through stop-1
a[start:]      # items start through the rest of the array
a[:stop]       # items from the beginning through stop-1
a[:]           # a copy of the whole array

There is also the step value, which can be used with any of the above:

a[start:stop:step] # start through not past stop, by step

The key point to remember is that the :stop value represents the first value that is not in the selected slice. So, the difference between stop and start is the number of elements selected (if step is 1, the default).

The other feature is that start or stop may be a negative number, which means it counts from the end of the array instead of the beginning. So:

a[-1]    # last item in the array
a[-2:]   # last two items in the array
a[:-2]   # everything except the last two items

Similarly, step may be a negative number:

a[::-1]    # all items in the array, reversed
a[1::-1]   # the first two items, reversed
a[:-3:-1]  # the last two items, reversed
a[-3::-1]  # everything except the last two items, reversed

Python is kind to the programmer if there are fewer items than you ask for. For example, if you ask for a[:-2] and a only contains one element, you get an empty list instead of an error. Sometimes you would prefer the error, so you have to be aware that this may happen.

Relation to slice() object

The slicing operator [] is actually being used in the above code with a slice() object using the : notation (which is only valid within []), i.e.:

a[start:stop:step]

is equivalent to:

a[slice(start, stop, step)]

Slice objects also behave slightly differently depending on the number of arguments, similarly to range(), i.e. both slice(stop) and slice(start, stop[, step]) are supported. To skip specifying a given argument, one might use None, so that e.g. a[start:] is equivalent to a[slice(start, None)] or a[::-1] is equivalent to a[slice(None, None, -1)].

While the :-based notation is very helpful for simple slicing, the explicit use of slice() objects simplifies the programmatic generation of slicing.

Agree with all above answers of using MutableList but you can also add/remove from List and get a new list as below.

val newListWithElement = existingList + listOf(element)
val newListMinusElement = existingList - listOf(element)

Or

val newListWithElement = existingList.plus(element)
val newListMinusElement = existingList.minus(element)

Mine was not working because I wanted an icon which was not released in the FA version I was using.

This answers why some icons shows but others no.

Pretty obvious but I guess some people still fall for this. Like me.

Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.

path.join returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.

For instance:

path.join('app/libs/oauth', '/../ssl')

resolves to app/libs/ssl

path.resolve, on the other hand, will resolve to an absolute path.

For instance, when you run:

path.resolve('bar', '/foo');

The path returned will be /foo since that is the first absolute path that can be constructed.

However, if you run:

path.resolve('/bar/bae', '/foo', 'test');

The path returned will be /foo/test again because that is the first absolute path that can be formed from right to left.

If you don't provide a path that specifies the root directory then the paths given to the resolve function are appended to the current working directory. So if your working directory was /home/mark/project/:

path.resolve('test', 'directory', '../back');

resolves to

/home/mark/project/test/back

Using __dirname is the absolute path to the directory containing the source file. When you use path.resolve or path.join they will return the same result if you give the same path following __dirname. In such cases it's really just a matter of preference.

• x += y is x = x + y
• x -= y is x = x - y
• x *= y is x = x * y
• x /= y is x = x / y
• x %= y is x = x % y
• x ^= y is x = x ^ y
• x &= y is x = x & y
• x |= y is x = x | y

and so on ...

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

However, I found that the second option only worked (OS X 10.6, MySQL 5.1.50) if the .plist has been loaded with:

sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysqld.plist

PS: I also found that I needed to unload the .plist to get an unrelated install of MAMP-MySQL to start / stop correctly. After running running this, MAMP-MySQL starts just fine:

sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

In order to use base_url(), you must first have the URL Helper loaded. This can be done either in application/config/autoload.php (on or around line 67):

$autoload['helper'] = array('url');

Or, manually:

$this->load->helper('url');

Once it's loaded, be sure to keep in mind that base_url() doesn't implicitly print or echo out anything, rather it returns the value to be printed:

echo base_url();

Remember also that the value returned is the site's base url as provided in the config file. CodeIgniter will accomodate an empty value in the config file as well:

If this (base_url) is not set then CodeIgniter will guess the protocol, domain and path to your installation.

application/config/config.php, line 13

Hope below image will help to understand:

Batch files have really very limited logic powers so the best you can hope to come up with is a good workaround that indirectly achieves what you want. That's not to say that you should feel they are inferior to a real language - they still demand the same attention to detail and manual debugging as a real application. It's just that you'll need to work a lot harder to make them do what you want in a robust manner.

For the OP's question it sounds like you require two specific files to exist. Just use a tally:

IF EXIST somefile.txt (
    set /a file1_status=1
)

IF EXIST someotehrfile.txt (
    set /a file2_status=1
)

set /a file_status_result=file1_status + file2_status

if %file_status_result% equ 2 (
    goto somefileexists
)

goto exit

:somefileexists
IF EXIST someotherfile.txt SET var=...

:exit

My example uses 3 variables, but you could just add 1 to file_result_status if the file exists. But if you want more granular control later in your batch file you can record the result for each file as I have done so you don't have to keep checking if a file exists later on.

I use Eclipse Indigo, and this is how I do it:

Window > Preferences > Startup and Shutdown > Workspaces

check box at the top of the window: "Prompt for workspace on startup"

For example, your remote host is example.com and remote login name is user1:

scp [email protected]:/path/to/file /path/to/store/file

And, if you want to verify that you HAVEN'T broken your relationships and introduced orphans, once you have re-armed your checks, i.e.

ALTER TABLE foo CHECK CONSTRAINT ALL

or

ALTER TABLE foo CHECK CONSTRAINT FK_something

then you can run back in and do an update against any checked columns like so:

UPDATE myUpdatedTable SET someCol = someCol, fkCol = fkCol, etc = etc

And any errors at that point will be due to failure to meet constraints.

The underlying XMLHttpRequest object used by jQuery will always silently follow redirects rather than return a 302 status code. Therefore, you can't use jQuery's AJAX request functionality to get the returned URL. Instead, you need to put all the data into a form and submit the form with the target attribute set to the value of the name attribute of the iframe:

$('#myIframe').attr('name', 'myIframe');

var form = $('<form method="POST" action="url.do"></form>').attr('target', 'myIframe');
$('<input type="hidden" />').attr({name: 'search', value: 'test'}).appendTo(form);

form.appendTo(document.body);
form.submit();

The server's url.do page will be loaded in the iframe, but when its 302 status arrives, the iframe will be redirected to the final destination.

homebrew Installer

Assuming you installed PostgreSQL with homebrew as referenced in check status of postgresql server Mac OS X and how to start postgresql server on mac os x: you can use the brew uninstall postgresql command.

EnterpriseDB Installer

If you used the EnterpriseDB installer then see the other answer in this thread.

The EnterpriseDB installer is what you get if you follow "download" links from the main Postgres web site. The Postgres team releases only source code, so the EnterpriseDB.com company builds installers as a courtesy to the community.

Postgres.app

You may have also used Postgres.app.

This double-clickable Mac app contains the Postgres engine.

Another method would be to do it sooner. You can create a Boolean variable and set it to true once you load data to the array. so all you really need is a simple if statement of when you load data into the array.

I needed something like that, so I went to the commons collections and used the SetUniqueList, but when I ran some performance test, I found that it seems not optimized comparing to the case if I want to use a Set and obtain an Array using the Set.toArray() method.

The SetUniqueTest took 20:1 time to fill and then traverse 100,000 Strings comparing to the other implementation, which is a big deal difference.

So, if you worry about the performance, I recommend you to use the Set and Get an Array instead of using the SetUniqueList, unless you really need the logic of the SetUniqueList, then you'll need to check other solutions...

Testing code main method:

public static void main(String[] args) {


SetUniqueList pq = SetUniqueList.decorate(new ArrayList());
Set s = new TreeSet();

long t1 = 0L;
long t2 = 0L;
String t;


t1 = System.nanoTime();
for (int i = 0; i < 200000; i++) {
    pq.add("a" + Math.random());
}
while (!pq.isEmpty()) {
    t = (String) pq.remove(0);
}
t1 = System.nanoTime() - t1;

t2 = System.nanoTime();
for (int i = 0; i < 200000; i++) {
    s.add("a" + Math.random());
}

s.clear();
String[] d = (String[]) s.toArray(new String[0]);
s.clear();
for (int i = 0; i < d.length; i++) {
    t = d[i];

}
t2 = System.nanoTime() - t2;

System.out.println((double)t1/1000/1000/1000); //seconds
System.out.println((double)t2/1000/1000/1000); //seconds
System.out.println(((double) t1) / t2);        //comparing results

}

It has copy, and as stated the JDK already has move.

Don't implement your own copy method. There are so many floating out there...

I just came up with this method which may be hardware intensive but it is working:

You can replace all characters which match the regex by an empty string.

This is a oneliner:

notMatched = re.sub(regex, "", string)

I used this because I was forced to use a very complex regex and couldn't figure out how to invert every part of it within a reasonable amount of time.

This will only return you the string result, not any match objects!

You might want to take a look at Joda Time which is a really good API for dealing with date/time. Even though if you don't really need it for the solution to your current question it is bound to save you pain in the future.

Here is a solution using only a custom adapter with a different view type for the empty situation.

public class EventAdapter extends 
    RecyclerView.Adapter<EventAdapter.ViewHolder> {

    private static final int VIEW_TYPE_EVENT = 0;
    private static final int VIEW_TYPE_DATE = 1;
    private static final int VIEW_TYPE_EMPTY = 2;

    private ArrayList items;

    public EventAdapter(ArrayList items) {
        this.items = items;
    }

    @Override
    public int getItemCount() {
        if(items.size() == 0){
            return 1;
        }else {
            return items.size();
        }
    }

    @Override
    public int getItemViewType(int position) {
        if (items.size() == 0) {
            return VIEW_TYPE_EMPTY;
        }else{
            Object item = items.get(position);
            if (item instanceof Event) {
                return VIEW_TYPE_EVENT;
            } else {
                return VIEW_TYPE_DATE;
            }
        }
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v;
        ViewHolder vh;
        if (viewType == VIEW_TYPE_EVENT) {
            v = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.item_event, parent, false);
            vh = new ViewHolderEvent(v);
        } else if (viewType == VIEW_TYPE_DATE) {
            v = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.item_event_date, parent, false);
            vh = new ViewHolderDate(v);
        } else {
            v = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.item_event_empty, parent, false);
            vh = new ViewHolder(v);
        }

        return vh;
    }

    @Override
    public void onBindViewHolder(EventAdapter.ViewHolder viewHolder, 
                                 final int position) {
        int viewType = getItemViewType(position);
        if (viewType == VIEW_TYPE_EVENT) {
            //...
        } else if (viewType == VIEW_TYPE_DATE) {
            //...
        } else if (viewType == VIEW_TYPE_EMPTY) {
            //...
        }
    }

    public static class ViewHolder extends ParentViewHolder {
        public ViewHolder(View v) {
            super(v);
        }
    }

    public static class ViewHolderDate extends ViewHolder {
        public ViewHolderDate(View v) {
            super(v);
        }
    }

    public static class ViewHolderEvent extends ViewHolder {
        public ViewHolderEvent(View v) {
            super(v);
        }
    }

}

if you need to select multiple columns from dataframe use 2 pairs of square brackets eg.

df[["product_id","customer_id","store_id"]]

I had a situation where I needed a separate but persistent name space. I used classes. I don't otherwise. Segregated but persistent names are closures.

>>> class f2:
...     def __init__(self):
...         self.a = 0
...     def __call__(self, arg):
...         self.a += arg
...         return(self.a)
...
>>> f=f2()
>>> f(2)
2
>>> f(2)
4
>>> f(4)
8
>>> f(8)
16

# **OR**
>>> f=f2() # **re-initialize**
>>> f(f(f(f(2)))) # **nested**
16

# handy in list comprehensions to accumulate values
>>> [f(i) for f in [f2()] for i in [2,2,4,8]][-1] 
16

This should help if you need a publicly exposed website but you're on a dev pc. Also to answer (I can't comment yet): "How do I post to an internal only running development server with this? – stryba "

NGROK creates a secure public URL to a local webserver on your development machine (Permanent URLs available for a fee, temporary for free).
1) Run ngrok.exe to open command line (on desktop)
2) Type ngrok.exe http 80 to start a tunnel,
3) test by browsing to the displayed web address which will forward and display the local default 80 page on your dev pc

Then use some of the tools recommended above to POST to your ngrok site ('https://xxxxxx.ngrok.io') to test your local code.

https://ngrok.com/ ngrok

You can use reflection to iterate over the object's field, and set them. You'd obviously need some sort of mapping between types or even field names and required default values but this can be done quite easily in a loop. For example:

for (Field f : obj.getClass().getFields()) {
  f.setAccessible(true);
  if (f.get(obj) == null) {
     f.set(obj, getDefaultValueForType(f.getType()));
  }
}

[Update]

With modern Java, you can use annotations to set the default values for fields on a per class basis. A complete implementation might look like this:

// DefaultString.java:
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

@Retention(RetentionPolicy.RUNTIME)
public @interface DefaultString {
    String value();
}

// DefaultInteger.java:
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

@Retention(RetentionPolicy.RUNTIME)
public @interface DefaultInteger {
    int value();
}

// DefaultPojo.java:
import java.lang.annotation.Annotation;
import java.lang.reflect.Field;

public class DefaultPojo {

    public void setDefaults() {
        for (Field f : getClass().getFields()) {
            f.setAccessible(true);
            try {
                if (f.get(this) == null) {
                    f.set(this, getDefaultValueFromAnnotation(f.getAnnotations()));
                }
            } catch (IllegalAccessException e) { // shouldn't happen because I used setAccessible
            }
        }
    }

    private Object getDefaultValueFromAnnotation(Annotation[] annotations) {
        for (Annotation a : annotations) {
            if (a instanceof DefaultString)
                return ((DefaultString)a).value();
            if (a instanceof DefaultInteger)
                return ((DefaultInteger)a).value();
        }
        return null;
    }

}

// Test Pojo
public class TestPojo extends DefaultPojo {
    @DefaultString("Hello world!")
    public String stringValue;
    @DefaultInteger(42);
    public int integerValue;
}

Then default values for a TestPojo can be set just by running test.setDetaults()

So, by unset'ting the array index 2, you essentially remove that element in the array and decrement the array size (?).

I made my own test..

foo=(5 6 8)
echo ${#foo[*]}
unset foo
echo ${#foo[*]}

Which results in..

3
0

So just to clarify that unset'ting the entire array will in fact remove it entirely.

You can do:

#if MACRO0
    //code...
#elif MACRO1
    //code...
#endif

…where the identifier can be:

    __linux__       Defined on Linux
    __sun           Defined on Solaris
    __FreeBSD__     Defined on FreeBSD
    __NetBSD__      Defined on NetBSD
    __OpenBSD__     Defined on OpenBSD
    __APPLE__       Defined on Mac OS X
    __hpux          Defined on HP-UX
    __osf__         Defined on Tru64 UNIX (formerly DEC OSF1)
    __sgi           Defined on Irix
    _AIX            Defined on AIX
    _WIN32          Defined on Windows

You can convert it into string by using JSON and store it as string.

For example,

In [3]: json.dumps([[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]])

Out[3]: '[[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]]'

You can add a method into your class to convert it automatically for you.

import json


class Foobar(models.Model):
    foo = models.CharField(max_length=200)

    def set_foo(self, x):
        self.foo = json.dumps(x)

    def get_foo(self):
        return json.loads(self.foo)

If you're using Django 1.9 and postgresql, there is a new class called JSONField, you should use it instead. Here is a link to it

There is a good talk about PostgreSQL JSONs and Arrays on youtube. Watch it, it has very good information.

The for attribute shows that this label stands for related input field, or check box or radio button or any other data entering field associated with it. for example

<li>
    <label>{translate:blindcopy}</label>
    <a class="" href="#" title="{translate:savetemplate}" onclick="" ><i class="fa fa-list" class="button" ></i></a> &nbsp 
            <input type="text" id="BlindCopy" name="BlindCopy" class="splitblindcopy" />

</li>

It is Yoda condition writing in different manner

In java

String myString = null;
if (myString.equals("foobar")) { /* ... */ } //Will give u null pointer

yoda condition

String myString = null;
if ("foobar".equals(myString)) { /* ... */ } // will be false 

The most simple solution is to use LINQ and then transform the result to a DataTable

    //data is a DataTable that you want to change

Docker CE is not supported on RHEL. Any way you are trying to get around that is not a supported way. You can see the supported platforms in the Docker Documentation. I suggest you either use a supported OS, or switch to Enterprise Edition.

user1462299's response works great, but if you include fragments, they will use the original activities theme. To apply the theme to all fragments as well you can override the getTheme() method of the Context instead:

@Override
public Resources.Theme getTheme() {
    Resources.Theme theme = super.getTheme();
    if(useAlternativeTheme){
        theme.applyStyle(R.style.AlternativeTheme, true);
    }
    // you could also use a switch if you have many themes that could apply
    return theme;
}

You do not need to call setTheme() in the onCreate() Method anymore. You are overriding every request to get the current theme within this context this way.

Based on previous answers (swift 4)

You can use immediateConstraints when you don't want to crawl entire hierarchies.

extension UIView {
/**
 * Deactivates immediate constraints that target this view (self + superview)
 */
func deactivateImmediateConstraints(){
    NSLayoutConstraint.deactivate(self.immediateConstraints)
}
/**
 * Deactivates all constrains that target this view
 */
func deactiveAllConstraints(){
    NSLayoutConstraint.deactivate(self.allConstraints)
}
/**
 * Gets self.constraints + superview?.constraints for this particular view
 */
var immediateConstraints:[NSLayoutConstraint]{
    let constraints = self.superview?.constraints.filter{
        $0.firstItem as? UIView === self || $0.secondItem as? UIView === self
        } ?? []
    return self.constraints + constraints
}
/**
 * Crawls up superview hierarchy and gets all constraints that affect this view
 */
var allConstraints:[NSLayoutConstraint] {
    var view: UIView? = self
    var constraints:[NSLayoutConstraint] = []
    while let currentView = view {
        constraints += currentView.constraints.filter {
            return $0.firstItem as? UIView === self || $0.secondItem as? UIView === self
        }
        view = view?.superview
    }
    return constraints
}
}

For comparing 2 strings, either use the built in function strcmp() using header file string.h

if(strcmp(a,b)==0)
    printf("Entered strings are equal");
else
    printf("Entered strings are not equal");

OR you can write your own function like this:

int string_compare(char str1[], char str2[])
{
    int ctr=0;

    while(str1[ctr]==str2[ctr])
    {
        if(str1[ctr]=='\0'||str2[ctr]=='\0')
            break;
        ctr++;
    }
    if(str1[ctr]=='\0' && str2[ctr]=='\0')
        return 0;
    else
        return -1;
}

Elvis operator:

?: is the Elvis operator. This is a binary operator which does the following:

Coerces the value left of ?: to a boolean and checks if it is true. If true it will return the expression on the left side, if false it will return the expression on the right side.

Example:

var_dump(0 ?: "Expression not true");     // expression returns: Expression not true
var_dump("" ?: "Expression not true");    // expression returns: Expression not true
var_dump("hi" ?: "Expression not true");  // expression returns string hi
var_dump(null ?: "Expression not true");  // expression returns: Expression not true
var_dump(56 ?: "Expression not true");    // expression return int 56

When to use:

The Elvis operator is basically shorthand syntax for a specific case of the ternary operator which is:

$testedVar ? $ testedVar : $otherVar;

The Elvis operator will make the syntax more consise in the following manner:

$testedVar ?: $otherVar;

The error means that the dependency injector was unable to locate the dependency 'ngResource'. The script tag in the accepted answer provides this dependency.

You will also get the same error if you add any custom modules in the dependencies but did not add the script tag for including the '.js' file containing the dependency.

Gooye if it's possible to use Joda Time in your project then this code works for me:

String dateStr = "2012-10-01T09:45:00.000+02:00";
String customFormat = "yyyy-MM-dd HH:mm:ss";

DateTimeFormatter dtf = ISODateTimeFormat.dateTime();
LocalDateTime parsedDate = dtf.parseLocalDateTime(dateStr);

String dateWithCustomFormat = parsedDate.toString(DateTimeFormat.forPattern(customFormat));
System.out.println(dateWithCustomFormat);

First of all, I can only agree that Arrays.asList(T...) is clearly the best solution for Wrapper types or arrays with non-primtive datatypes. This method calls a constructor of a simple private static AbstractList implementation in the Arrays class which basically saves the given array reference as field and simulates a list by overriding the needed methods.

If you can choose between a primtive type or a Wrapper type for your array, I would use the Wrapper type for such situations but of course, it's not always useful or required. There would be only two possibilities you can do:

1) You can create a class with a static method for each primitive datatype array (boolean, byte, short, int, long, char, float, double returning an Iterable<WrapperType>. These methods would use anonymous classes of Iterator (besides Iterable) which are allowed to contain the reference of the comprising method's argument (for example an int[]) as field in order to implement the methods.

-> This approach is performant and saves you memory (except for the memory of the newly created methods, even though, using Arrays.asList() would take memory in the same way)

2) Since arrays don't have methods (as to be read on the side you linked) they can't provide an Iterator instance either. If you really are too lazy to write new classes, you must use an instance of an already existing class that implements Iterable because there is no other way around than instantiating Iterable or a subtype.
The ONLY way to create an existing Collection derivative implementing Iterable is to use a loop (except you use anonymous classes as described above) or you instantiate an Iterable implementing class whose constructor allows a primtive type array (because Object[] doesn't allow arrays with primitive type elements) but as far as I know, the Java API doesn't feature a class like that.

The reason for the loop can be explained easily:
for each Collection you need Objects and primtive datatypes aren't objects. Objects are much bigger than primitive types so that they require additional data which must be generated for each element of the primitive type array. That means if two ways of three (using Arrays.asList(T...) or using an existing Collection) require an aggregate of objects, you need to create for each primitive value of your int[] array the wrapper object. The third way would use the array as is and use it in an anonymous class as I think it's preferable due to fast performance.

There is also a third strategy using an Object as argument for the method where you want to use the array or Iterable and it would require type checks to figure out which type the argument has, however I wouldn't recommend it at all as you usually need to consider that the Object hasn't always the required type and that you need seperate code for certain cases.

In conclusion, it's the fault of Java's problematic Generic Type system which doesn't allow to use primitive types as generic type which would save a lot of code by using simply Arrays.asList(T...). So you need to program for each primitive type array, you need, such a method (which basically makes no difference to the memory used by a C++ program which would create for each used type argument a seperate method.

1. I firstly added one off static table with ALL possibilities of my wildcard results (this company has a 4 character nvarchar code as their localities and they wildcard their locals) i.e. they may have 456? which would give them 456[1] to 456[Z] i.e 0-9 & a-z

2. I had to write a script to pull the current user (declare them) and pull the masks for the declared user.

3. Create some temporary tables just basic ones to rank the row numbers for this current user

4. loop through each result (YOUR Or this Or that etc...)

5. Insert into the test Table.

Here is the script I used:

Drop Table #UserMasks 
Drop Table #TESTUserMasks 

Create Table #TESTUserMasks (
    [User] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

Create Table #UserMasks (
    [RN] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

DECLARE @User INT
SET @User = 74054

Insert Into #UserMasks 
select ROW_NUMBER() OVER ( PARTITION BY ProntoUserID ORDER BY Id DESC) AS RN,
       REPLACE(mask,'?','') Mask
from dbo.Access_Masks 
where prontouserid = @User

DECLARE @TopFlag INT
SET @TopFlag = 1

WHILE (@TopFlag <=(select COUNT(*) from #UserMasks))
BEGIN
    Insert Into #TestUserMasks 
    select (@User),Code from dbo.MaskArrayLookupTable 
    where code like (select Mask + '%' from #UserMasks Where RN = @TopFlag)

    SET @TopFlag = @TopFlag + 1
END
GO

select * from #TESTUserMasks

If you are reading unicode escaped chars from a file, then you will have a tough time doing that because the string will be read literally along with an escape for the back slash:

my_file.txt

Blah blah...
Column delimiter=;
Word delimiter=\u0020 #This is just unicode for whitespace

.. more stuff

Here, when you read line 3 from the file the string/line will have:

"Word delimiter=\u0020 #This is just unicode for whitespace"

and the char[] in the string will show:

{...., '=', '\\', 'u', '0', '0', '2', '0', ' ', '#', 't', 'h', ...}

Commons StringUnescape will not unescape this for you (I tried unescapeXml()). You'll have to do it manually as described here.

So, the sub-string "\u0020" should become 1 single char '\u0020'

But if you are using this "\u0020" to do String.split("... ..... ..", columnDelimiterReadFromFile) which is really using regex internally, it will work directly because the string read from file was escaped and is perfect to use in the regex pattern!! (Confused?)

Your URL should be jdbc:sqlserver://server:port;DatabaseName=dbname
and Class name should be like com.microsoft.sqlserver.jdbc.SQLServerDriver
Use MicrosoftSQL Server JDBC Driver 2.0

Or if you use gmaps.js, call:

map.refresh();

when your div is shown.

You can't call something on the entire viewModel, but on an individual observable you can call myObservable.valueHasMutated() to notify subscribers that they should re-evaluate. This is generally not necessary in KO, as you mentioned.

Maybe this will help:

<select onchange="location = this.value;">
 <option value="home.html">Home</option>
 <option value="contact.html">Contact</option>
 <option value="about.html">About</option>
</select>

here's the best of both worlds.

I also "like" underscores, besides all your positive points about them, there is also a certain old-school style to them.

So what I do is use underscores and simply add a small rewrite rule to your Apache's .htaccess file to re-write all underscores to hyphens.

Copying the VM files onto an external HDD and then bringing it in to the destination will take a lot longer and requires multiple steps. Using vCenter Converter Standalone Client will do everything for you and is much faster. No external HDD required. Not sure where you got the cloning part from. vCenter Converter Standalone Client is simply copying the VM files by importing and exporting from source to destination, shutdown the source VM, then register the VM at destination and power on. All in one step. Takes about 1 min to set that up vCenter Converter Standalone Client.

NOTE: Though this is possible, it is not at all recommended as it kind of destroys the reason for inheritance. The best way would be to restructure your application design so that there are NO parent to child dependencies. A parent should not ever need to know its children or their capabilities.

However.. you should be able to do it like:

void calculate(Person p) {
    ((Student)p).method();
}

a safe way would be:

void calculate(Person p) {
    if(p instanceof Student) ((Student)p).method();
}

You haven't specified any keyframes. I made it work here.

div {
    margin: 20px;
    width: 100px; 
    height: 100px;    
    background: #f00;
    -webkit-animation: spin 4s infinite linear;
}

@-webkit-keyframes spin {
    0%  {-webkit-transform: rotate(0deg);}
    100% {-webkit-transform: rotate(360deg);}   
}

You can actually do lots of really cool stuff with this. Here is one I made earlier.

Works properly on Andorid 8.1:

Updated sample (without any deprecated code):

public NotificationBattery(Context context) {
    this.mCtx = context;

    mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
            .setContentTitle(context.getString(R.string.notification_title_battery))
            .setSmallIcon(R.drawable.ic_launcher)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setChannelId(CHANNEL_ID)
            .setOnlyAlertOnce(true)
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .setWhen(System.currentTimeMillis() + 500)
            .setGroup(GROUP)
            .setOngoing(true);

    mRemoteViews = new RemoteViews(context.getPackageName(), R.layout.notification_view_battery);

    initBatteryNotificationIntent();

    mBuilder.setContent(mRemoteViews);

    mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    if (AesPrefs.getBooleanRes(R.string.SHOW_BATTERY_NOTIFICATION, true)) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, context.getString(R.string.notification_title_battery),
                    NotificationManager.IMPORTANCE_DEFAULT);
            channel.setShowBadge(false);
            channel.setSound(null, null);
            mNotificationManager.createNotificationChannel(channel);
        }
    } else {
        mNotificationManager.cancel(Const.NOTIFICATION_CLIPBOARD);
    }
}

Old snipped (it's a different app - not related to the code above):

@Override
public int onStartCommand(Intent intent, int flags, final int startId) {
    Log.d(TAG, "onStartCommand");

    String CHANNEL_ONE_ID = "com.kjtech.app.N1";
    String CHANNEL_ONE_NAME = "Channel One";
    NotificationChannel notificationChannel = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        notificationChannel = new NotificationChannel(CHANNEL_ONE_ID,
                CHANNEL_ONE_NAME, IMPORTANCE_HIGH);
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setShowBadge(true);
        notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.createNotificationChannel(notificationChannel);
    }

    Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    Notification notification = new Notification.Builder(getApplicationContext())
            .setChannelId(CHANNEL_ONE_ID)
            .setContentTitle(getString(R.string.obd_service_notification_title))
            .setContentText(getString(R.string.service_notification_content))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setLargeIcon(icon)
            .build();

    Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    notification.contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);

    startForeground(START_FOREGROUND_ID, notification);

    return START_STICKY;
}

If the string can not be converted to an integer, then

• int.Parse() will throw an exception
• int.TryParse() will return false (but not throw an exception)

// html code

<input id="idFdate" type="date" />

// javascript code on main load function

function loadFunction() {
    // body...
    var today = new Date();
    var dd = today.getDate();
    var mm = today.getMonth()+1; //January is 0!
    var yyyy = today.getFullYear();

    if(dd<10){
        dd='0'+dd;
    } 
    if(mm<10){
        mm='0'+mm;
    } 

    today = yyyy+'-'+mm+'-'+dd;                
    document.getElementById("idFdate").defaultValue =today+"";
}

Here's some code that avoids getting the count to instantiate an array, but uses an ArrayList instead and just before returning converts the ArrayList to the needed array type.

Note that Supervisor class here implements ISupervisor interface, but in Java you can't cast from object[] (that ArrayList's plain toArray() method returns) to ISupervisor[] (as I think you are able to do in C#), so you have to iterate through all list items and populate the result array.

/**
 * Get Supervisors for given program id
 * @param connection
 * @param programId
 * @return ISupervisor[]
 * @throws SQLException
 */
public static ISupervisor[] getSupervisors(Connection connection, String programId)
  throws SQLException
{
  ArrayList supervisors = new ArrayList();

  PreparedStatement statement = connection.prepareStatement(SQL.GET_SUPERVISORS);
  try {
    statement.setString(SQL.GET_SUPERVISORS_PARAM_PROGRAMID, programId);
    ResultSet resultSet = statement.executeQuery();  

    if (resultSet != null) {
      while (resultSet.next()) {
        Supervisor s = new Supervisor();
        s.setId(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ID));
        s.setFirstName(resultSet.getString(SQL.GET_SUPERVISORS_RESULT_FIRSTNAME));
        s.setLastName(resultSet.getString(SQL.GET_SUPERVISORS_RESULT_LASTNAME));
        s.setAssignmentCount(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ASSIGNMENT_COUNT));
        s.setAssignment2Count(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ASSIGNMENT2_COUNT));
        supervisors.add(s);
      }
      resultSet.close();
    }
  } finally {
    statement.close();
  }

  int count = supervisors.size();
  ISupervisor[] result = new ISupervisor[count];
  for (int i=0; i<count; i++)
    result[i] = (ISupervisor)supervisors.get(i);
  return result;
}

When you create an empty project, this line is commented in Gemfile. Just uncomment it and bundle!

gem 'therubyracer', :platforms => :ruby

In a nutshell :

-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record

-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

More browser supported and more flexible way of doing that is using a normal loop, something like:

const arr = ['a', 'b', 'c'],
obj = {};

for (let i=0; i<arr.length; i++) {
   obj[i] = arr[i];
}

But also the modern way could be using the spread operator, like:

{...arr}

Or Object assign:

Object.assign({}, ['a', 'b', 'c']);

Both will return:

{0: "a", 1: "b", 2: "c"}

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

Just to explain:

2011-02-15 is being interpreted literally as a mathematical operation, to which the answer is 1994.

This, then, is being interpreted as 1994 days since the origin of date (Jan 1st 1900).

1994 days = 5 years, 6 months, 18 days = June 18th 1905

So, if you don't want to to the calculation each time you want compare a date to a particular value use the standard: Compare the value of the toString() function of date object to the string like this :

set @TEST  ='2011-02-05'

An int array without elements is not necessarily null. It will only be null if it hasn't been allocated yet. See this tutorial for more information about Java arrays.

You can test the array's length:

void foo(int[] data)
{
  if(data.length == 0)
    return;
}

Is this what you are looking for? Otherwise, let me know and I will remove this post.

Window->Show View->Other->General->Project Explorer

Or

Window->Open Perspective->Other->Java (default)

People already mentioned that

Task.Run(A);

Is equivalent to

Task.Factory.StartNew(A, CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);

But no one mentioned that

Task.Factory.StartNew(A);

Is equivalent to:

Task.Factory.StartNew(A, CancellationToken.None, TaskCreationOptions.None, TaskScheduler.Current);

As you can see two parameters are different for Task.Run and Task.Factory.StartNew:

1. TaskCreationOptions - Task.Run uses TaskCreationOptions.DenyChildAttach which means that children tasks can not be attached to the parent, consider this:

   var parentTask = Task.Run(() =>
   {
       var childTask = new Task(() =>
       {
           Thread.Sleep(10000);
           Console.WriteLine("Child task finished.");
       }, TaskCreationOptions.AttachedToParent);
       childTask.Start();
   
       Console.WriteLine("Parent task finished.");
   });
   
   parentTask.Wait();
   Console.WriteLine("Main thread finished.");
   

   When we invoke parentTask.Wait(), childTask will not be awaited, even though we specified TaskCreationOptions.AttachedToParent for it, this is because TaskCreationOptions.DenyChildAttach forbids children to attach to it. If you run the same code with Task.Factory.StartNew instead of Task.Run, parentTask.Wait() will wait for childTask because Task.Factory.StartNew uses TaskCreationOptions.None

2. TaskScheduler - Task.Run uses TaskScheduler.Default which means that the default task scheduler (the one that runs tasks on Thread Pool) will always be used to run tasks. Task.Factory.StartNew on the other hand uses TaskScheduler.Current which means scheduler of the current thread, it might be TaskScheduler.Default but not always. In fact when developing Winforms or WPF applications it is required to update UI from the current thread, to do this people use TaskScheduler.FromCurrentSynchronizationContext() task scheduler, if you unintentionally create another long running task inside task that used TaskScheduler.FromCurrentSynchronizationContext() scheduler the UI will be frozen. A more detailed explanation of this can be found here

So generally if you are not using nested children task and always want your tasks to be executed on Thread Pool it is better to use Task.Run, unless you have some more complex scenarios.

There are workarounds but no clean/short/sweet way to do it with streams and to be honest, you would probably be better off with:

int idx = 0;
for (Param p : params) query.bind(idx++, p);

Or the older style:

for (int idx = 0; idx < params.size(); idx++) query.bind(idx, params.get(idx));

Please read the user notes for this method:

This:

STR_TO_DATE(t.datestring, '%d/%m/%Y')

...will convert the string into a datetime datatype. To be sure that it comes out in the format you desire, use DATE_FORMAT:

DATE_FORMAT(STR_TO_DATE(t.datestring, '%d/%m/%Y'), '%Y-%m-%d')

If you can't change the datatype on the original column, I suggest creating a view that uses the STR_TO_DATE call to convert the string to a DateTime data type.

The shortest and best way is already answered, but the first thing I thought of was the mathematical way, so here it is:

def intlist(n):
    q = n
    ret = []
    while q != 0:
        q, r = divmod(q, 10) # Divide by 10, see the remainder
        ret.insert(0, r) # The remainder is the first to the right digit
    return ret

print intlist(3)
print '-'
print intlist(10)
print '--'
print intlist(137)

It's just another interesting approach, you definitely don't have to use such a thing in practical use cases.

You can try: a=[0,1,2,3,4,5,6,7,8,9];

[abs(x[1]-x[0]) for x in zip(a[1:],a[:-1])]

If you are using ssh and cloned with https this will not work. Clone with ssh and then push and pulls should work as expected!

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u prefix on strings, i.e. u'€' or by decoding a string with mystr.decode('utf-8') using the appropriate encoding.

The best practice is to decode all text data as it's read, rather than decoding mid-program. The io module provides an open() method which decodes text data to Unicode strings as it's read.

ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write() method.

Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write() and adds the relevant header.

Presuming your input file is UTF-8 encoded (0xC2 is common UTF-8 lead byte), putting everything together, and using the with statement, your code should look like:

with io.open('myText.txt', "r", encoding='utf-8') as f:
    data = f.read()

root = ET.Element("add")
doc = ET.SubElement(root, "doc")

field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data

tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)

Output:

<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>

You could achieve this with the use of anchors. Or more precisely the non use of them.

Controls are anchored by default to the top left of the form which means when the form size will be changed, their distance from the top left side of the form will remain constant. If you change the control anchor to bottom left, then the control will keep the same distance from the bottom and left sides of the form when the form if resized.

Turning off the anchor in a direction will keep the control centered in that direction when resizing.

NOTE: Turning off anchoring via the properties window in VS2015 may require entering None, None (instead of default Top,Left)

I think you've created your project like this:

vue init webpack myproject

Well, now you can run

npm run build

Copy index.html and /dist/ folder into your website root directory. Done.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

Try this: B = A ( : ), or try the reshape function.

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/reshape.html

@media (max-width: 767px) {
    footer .text-right, 
    footer .text-left {
        text-align: center;
    } 
}

I updated @loddn's answer, making two changes

• max-width of xs screens in bootstrap is 767px (768px is the start of sm screens)
• (this one is a matter of preference) I used footer instead of col-* so that if the column widths change, the CSS doesn't need to be updated.

You can get entire post body into a POJO. Following is something similar

@RequestMapping(
    value = { "/api/pojo/edit" }, 
    method = RequestMethod.POST, 
    produces = "application/json", 
    consumes = ["application/json"])
@ResponseBody
public Boolean editWinner( @RequestBody Pojo pojo) { 

Where each field in Pojo (Including getter/setters) should match the Json request object that the controller receives..

Import System.Windows.Forms binary to the test solution and call the following two LOC on clicking the Upload button on the UI.

        // Send the file path and enter file path and wait.
        System.Windows.Forms.SendKeys.SendWait("complete path of the file");
        System.Windows.Forms.SendKeys.SendWait("{ENTER}");

If you're using Bootstrap 3, you can use the embed-responsive class and set the padding bottom as the height divided by the width plus a little extra for toolbars. For example, to display an 8.5 by 11 PDF, use 130% (11/8.5) plus a little extra (20%).

<div class='embed-responsive' style='padding-bottom:150%'>
    <object data='URL.pdf' type='application/pdf' width='100%' height='100%'></object>
</div>

Here's the Bootstrap CSS:

.embed-responsive {
    position: relative;
    display: block;
    height: 0;
    padding: 0;
    overflow: hidden;
}

Another alternative is to use .SDcols

cols = paste0("V", c(1,2,3,5))
dt[, .SD, .SDcols=-cols]

If you're using spring >= 3.0, try using Springs @Configuration annotation to define part of the application context

@Configuration
@ImportResource("com/blah/blurk/rest-of-config.xml")
public class DaoTestConfiguration {

    @Bean
    public ApplicationService applicationService() {
        return mock(ApplicationService.class);
    }

}

If you don't want to use the @ImportResource, it can be done the other way around too:

<beans>
    <!-- rest of your config -->

    <!-- the container recognize this as a Configuration and adds it's beans 
         to the container -->
    <bean class="com.package.DaoTestConfiguration"/>
</beans>

For more information, have a look at spring-framework-reference : Java-based container configuration

Just add <br> where you would like to make the new line.

$S$: a set of shops
<br>
$I$: a set of items M wants to get

Because jupyter notebook markdown cell is a superset of HTML.
http://jupyter-notebook.readthedocs.io/en/latest/examples/Notebook/Working%20With%20Markdown%20Cells.html

Note that newlines using <br> does not persist when exporting or saving the notebook to a pdf (using "Download as > PDF via LaTeX"). It is probably treating each <br> as a space.

In my case it was a failed import to eclipse. I had to delete the project from eclipse (without deleting form the filesystem of course) and reimport it. After that the error was gone immediately.

In my case, after some refactoring in EF6, my tests were failing with the same error message as the original poster but my solution had nothing to do with the DateTime fields.

I was just missing a required field when creating the entity. Once I added the missing field, the error went away. My entity does have two DateTime? fields but they weren't the problem.

If you want "insert or replace" semantics, use this syntax:

A[key] = value;     // <-- insert or replace semantics

It's more efficient and readable than calls involving "ContainsKey()" or "Remove()" prior to "Add()".

So in your case:

rct3Features[items[0]] = items[1];

npm --depth 9999 update fixed the issue for me--apparently because package-lock.json was insisting on the outdated versions.

You should use the grep -q flag for quiet output. See the man pages below:

man grep output :

 General Output Control

  -q, --quiet, --silent
              Quiet;  do  not write anything to standard output.  Exit immediately with zero status
              if any match is  found,  even  if  an  error  was  detected.   Also  see  the  -s  or
              --no-messages option.  (-q is specified by POSIX.)

This KornShell (ksh) script demos the grep quiet output and is a solution to your question.

Adding this line worked for me. This in fact trusts all the certificates as mentioned here. However, this can be used primarily for troubleshooting. If this works for you, then it means that the certificate of the remote server is not added as a trusted certificate in your machine.

System.Net.ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(RemoteServerCertificateValidationCallback);

Full code is

private void sendAMail(String toAddress, String messageBody)
        {
            String msg = "Sending mail to : " + toAddress;

            MailMessage mail = new MailMessage();
            mail.To.Add(toAddress);
            mail.From = new MailAddress("[email protected]");
            mail.Subject = "Subject: Test Mail";
            mail.Body = messageBody;
            mail.IsBodyHtml = true;            

            //Added this line here
            System.Net.ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(RemoteServerCertificateValidationCallback);
            SmtpClient smtp = new SmtpClient();

            smtp.Host = "myhostname.com";            
            smtp.Credentials = new System.Net.NetworkCredential("[email protected]", "");
            smtp.EnableSsl = true;
            smtp.Port = 587;            
            smtp.Send(mail);            
        }

docker top <container ID>

You can use max(value, run)

The function max takes any number of arguments, or (alternatively) an iterable, and returns the maximum value.

The agg function will do this for you. Pass the columns and function as a dict with column, output:

df.groupby(['Country', 'Item_Code']).agg({'Y1961': np.sum, 'Y1962': [np.sum, np.mean]})  # Added example for two output columns from a single input column

This will display only the group by columns, and the specified aggregate columns. In this example I included two agg functions applied to 'Y1962'.

To get exactly what you hoped to see, included the other columns in the group by, and apply sums to the Y variables in the frame:

df.groupby(['Code', 'Country', 'Item_Code', 'Item', 'Ele_Code', 'Unit']).agg({'Y1961': np.sum, 'Y1962': np.sum, 'Y1963': np.sum})

Explanation from the Preshing on Programming blog:

It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:

 with open('output.txt', 'w') as f:
     f.write('Hi there!')

The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.

If you are using the table interface you can type in NULL (all caps)

otherwise you can run an update statement where you could:

Update table set ColumnName = NULL where [Filter for record here]

With ES6 MDN docs .includes()

"FooBar".includes("oo"); // true

"FooBar".includes("foo"); // false

"FooBar".includes("oo", 2); // false

E: Not suported by IE - instead you can use the Tilde opperator ~ (Bitwise NOT) with .indexOf()

~"FooBar".indexOf("oo"); // -2 -> true

~"FooBar".indexOf("foo"); // 0 -> false

~"FooBar".indexOf("oo", 2); // 0 -> false

Used with a number, the Tilde operator effective does ~N => -(N+1). Use it with double negation !! (Logical NOT) to convert the numbers in bools:

!!~"FooBar".indexOf("oo"); // true

!!~"FooBar".indexOf("foo"); // false

!!~"FooBar".indexOf("oo", 2); // false

 

Please note, that this only applies for Ubuntu 14.04 LTS and newer releases.

In my Ubuntu 14.04 LTS, the document root was set to /var/www/html. It was configured in the following file:

/etc/apache2/sites-available/000-default.conf

So just do a

sudo nano /etc/apache2/sites-available/000-default.conf

and change the following line to what you want:

DocumentRoot /var/www/html

Also do a

sudo nano /etc/apache2/apache2.conf

and find this

<Directory /var/www/html/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>

and change /var/www/html to your preferred directory

and save it.

After you saved your changes, just restart the apache2 webserver and you'll be done :)

sudo service apache2 restart

What does return; mean?

return; really means it returns nothing void. That's it.

why return; or other codes can write below the statement of System.exit(0);

It is allowed since compiler doesn't know calling System.exit(0) will terminate the JVM. The compiler will just give a warning - unnecessary return statement

Use the JSON.stringify() to get the string in JSON format, ensure that while making the AJAX call you pass below mentioned attributes:

• contentType: 'application/json'

Below is the give jquery code to make ajax post call to asp.net web api:

var product =_x000D_
    JSON.stringify({_x000D_
        productGroup: "Fablet",_x000D_
        productId: 1,_x000D_
        productName: "Lumia 1525 64 GB",_x000D_
        sellingPrice: 700_x000D_
    });_x000D_
_x000D_
$.ajax({_x000D_
    URL: 'http://localhost/api/Products',_x000D_
    type: 'POST',_x000D_
    contentType: 'application/json',_x000D_
    data: product,_x000D_
    success: function (data, status, xhr) {_x000D_
        alert('Success!');_x000D_
    },_x000D_
    error: function (xhr, status, error) {_x000D_
        alert('Update Error occurred - ' + error);_x000D_
    }_x000D_
});

If you need a cross-platform solution, try Boost's Program Options library.

df.loc[:,'industry'] = 'yyy'

This does the magic. You are to add '.loc' with ':' for all rows. Hope it helps

You can use gcc, in Terminal, by doing gcc -c tat.c -o tst

however, it doesn't come installed by default. You have to install the XCode package from tour install disc or download from http://developer.apple.com

Here is where to download past developer tools from, which includes XCode 3.1, 3.0, 2.5 ...

http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wo/5.1.17.2.1.3.3.1.0.1.1.0.3.3.3.3.1

exec is for statement and does not return anything. eval is for expression and returns value of expression.

expression means "something" while statement means "do something".

Functions in SQL Server, as in mathematics, can not be used to modify the database. They are intended to be read only and can help developer to implement command-query separation. In other words, asking a question should not change the answer. When your program needs to modify the database use a stored procedure instead.

The expression $(document).ready(function() deprecated in jQuery3.

See working fiddle with jQuery 3 here

Take into account I didn't include the showless button.

Here's the code:

JS

$(function () {
    x=3;
    $('#myList li').slice(0, 3).show();
    $('#loadMore').on('click', function (e) {
        e.preventDefault();
        x = x+5;
        $('#myList li').slice(0, x).slideDown();
    });
});

CSS

#myList li{display:none;
}
#loadMore {
    color:green;
    cursor:pointer;
}
#loadMore:hover {
    color:black;
}

You can use the following command :

$ grep "phpmyadmin" $path_to_access.log | grep -Po "^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" | sort | uniq | xargs -I% sudo iptables -A INPUT -s % -j DROP 

Explanation:

Make sure your IP isn't listed before piping through iptables drop!!

This will first find all lines in $path_to_access.log that have phpmyadmin in them,

then grep out the ip address from the start of the line,

then sort and unique them,

then add a rule to drop them in iptables

Again, just edit in echo % at the end instead of the iptables command to make sure your IP isn't in there. Don't inadvertently ban your access to the server!

Limitations

You may need to change the grep part of the command if you're on mac or any system that doesn't have grep -P. I'm not sure if all systems start with xargs, so that might need to be installed too. It's super useful anyway if you do a lot of bash.

VS Code 1.6.0 and Greater

As mentioned by aloisdg below, editor.renderWhitespace is now an enum taking either none, boundary or all. To view all whitespaces:

"editor.renderWhitespace": "all", 

Before VS Code 1.6.0

Before 1.6.0, you had to set editor.renderWhitespace to true:

"editor.renderWhitespace": true

You can use another tag instead of input and apply FontAwesome the normal way.

instead of your input with type image you can use this:

<i class="icon-search icon-2x"></i>

quick CSS:

.icon-search {
    color:white;
    background-color:black;
}

Here is a quick fiddle: DEMO

You can style it a little better and add event functionality, to the i object, which you can do by using a <button type="submit"> object instead of i, or with javascript.

The button sollution would be something like this:

<button type="submit" class="icon-search icon-large"></button>

And the CSS:

.icon-search {
    height:32px;
    width:32px;
    border: none;
    cursor: pointer;
    color:white;
    background-color:black;
    position:relative;
}

here is my fiddle updated with the button instead of i: DEMO

Update: Using FontAwesome on any tag

The problem with FontAwsome is that its stylesheet uses :before pseudo-elements to add the icons to an element - and pseudo elements don't work/are not allowed on input elements. This is why using FontAwesome the normal way will not work with input.

But there is a solution - you can use FontAwesome as a regular font like so:

CSS:

input[type="submit"] {
    font-family: FontAwesome;
}

HTML:

<input type="submit" class="search" value="&#xf002;" />

The glyphs can be passed as values of the value attribute. The ascii codes for the individual letters/icons can be found in the FontAwesome css file, you just need to change them into a HTML ascii number like \f002 to  and it should work.

Link to the FontAwesome ascii code (cheatsheet): fortawesome.github.io/Font-Awesome/cheatsheet

The size of the icons can be easily adjusted via font-size.

See the above example using an input element in a jsfidde:

DEMO

Update: FontAwesome 5

With FontAwesome version 5 the CSS required for this solution has changed - the font family name has changed and the font weight must be specified:

input[type="submit"] {
    font-family: "Font Awesome 5 Free"; // for the open access version
    font-size: 1.3333333333333333em;
    font-weight: 900;
}

See @WillFastie 's comment with link to updated fiddle bellow. Thanks!

There's a workaround to achieve it.

1. First, bind your iframe to a target page with relative url. The browsers will treat the site in iframe the same domain with your website.

2. In your web server, using a rewrite module to redirect request from the relative url to absolute url. If you use IIS, I recommend you check on IIRF module.

Update as of early 2015. xDomain is a widely used library to supports CORS on IE9 with limited extra coding.

Focus on mount

If you just want to focus an element when it mounts (initially renders) a simple use of the autoFocus attribute will do.

<input type="text" autoFocus />

Dynamic focus

to control focus dynamically use a general function to hide implementation details from your components.

React 16.8 + Functional component - useFocus hook

const FocusDemo = () => {

    const [inputRef, setInputFocus] = useFocus()

    return (
        <> 
            <button onClick={setInputFocus} >
               FOCUS
            </button>
            <input ref={inputRef} />
        </>
    )
    
}

const useFocus = () => {
    const htmlElRef = useRef(null)
    const setFocus = () => {htmlElRef.current &&  htmlElRef.current.focus()}

    return [ htmlElRef, setFocus ] 
}

      <> 
          <button onClick={this.inputFocus.setFocus}>

<div> is a block-level element and <span> is an inline element.

If you wanted to do something with some inline text, <span> is the way to go since it will not introduce line breaks that a <div> would.

As noted by others, there are some semantics implied with each of these, most significantly the fact that a <div> implies a logical division in the document, akin to maybe a section of a document or something, a la:

<div id="Chapter1">
   <p>Lorem ipsum dolor sit amet, <span id="SomeSpecialText1">consectetuer adipiscing</span> elit. Duis congue vehicula purus.</p>
   <p>Nam <span id="SomeSpecialText2">eget magna nec</span> sapien fringilla euismod. Donec hendrerit.</p> 
</div>

import jquery within <script> tag in your vue file.

I think this is the easiest way.

For example,

<script>
import $ from "jquery";

export default {
    name: 'welcome',
    mounted: function() {
        window.setTimeout(function() {
            $('.logo').css('opacity', 0);   
        }, 1000);
    } 
}
</script>

I tried the below and it worked like a charm :)

rec_list =  ['[email protected]', '[email protected]']
rec =  ', '.join(rec_list)

msg['To'] = rec

send_out = smtplib.SMTP('localhost')
send_out.sendmail(me, rec_list, msg.as_string())

Similar to the answer before there there is

location.host

The location global has more fun facts about the current url as well. ( protocol, host, port, pathname, search, hash )

Correct way to exclude default logging, and configure log4j for logging.

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter</artifactId>
 <exclusions>
     <exclusion>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-logging</artifactId>
     </exclusion>
 </exclusions>
</dependency>

Refer Spring Logging - How To.

In gradle, I needed to do this with several other dependencies:

configurations {
    all*.exclude module : 'spring-boot-starter-logging'
    all*.exclude module : 'logback-classic'
}

position: sticky;

The sticky element sticks on top of the page (top: 0) when you reach its scroll position.

See example: https://www.w3schools.com/css/tryit.asp?filename=trycss_position_sticky

The following should do the trick:

btn.Click += btn1_Click;

You don't need the assignment operator. append returns None.

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

External fragmentation
Total memory space is enough to satisfy a request or to reside a process in it, but it is not contiguous so it can not be used.

Internal fragmentation
Memory block assigned to process is bigger. Some portion of memory is left unused as it can not be used by another process.

const int WIDTH = 1024;
const int HEIGHT = 800;

I updated BigGridDemo to support multiple sheets.

There are two ways to interpret the input data; either -128 is the lowest value, and 127 is the highest (i.e. true signed data), or 0 is the lowest value, 127 is somewhere in the middle, and the next "higher" number is -128, with -1 being the "highest" value (that is, the most significant bit already got misinterpreted as a sign bit in a two's complement notation.

Assuming you mean the latter, the formally correct way is

signed char in = ...
unsigned char out = (in < 0)?(in + 256):in;

which at least gcc properly recognizes as a no-op.

import pandas as pd
import numpy as np
x = np.array( [1,1,1,2,2,2,5,25,1,1] )
print(dict(pd.Series(x).value_counts()))

This gives you: {1: 5, 2: 3, 5: 1, 25: 1}

Use round, floor or ceil methods to round it to the closest integer, along with intval() which is limited.

See ?"[" for a start ...

For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

After spending a good amount of time on this issue I found whenever I followed suggestions of using IIS to make a self signed certificate, I found that the Issued To and Issued by was not correct. SelfSSL.exe was the key to solving this problem. The following website not only provided a step by step approach to making self signed certificates, but also solved the Issued To and Issued by problem. Here is the best solution I found for making self signed certificates. If you'd prefer to see the same tutorial in video form click here.

A sample use of SelfSSL would look something like the following:

SelfSSL /N:CN=YourWebsite.com /V:1000 /S:2

SelfSSL /? will provide a list of parameters with explanation.
