I have just found this site – http://unused-css.com/

Looks good but I would need to thoroughly check its outputted 'clean' css before uploading it to any of my sites.

Also as with all these tools I would need to check it didn't strip id's and classes with no style but are used as JavaScript selectors.

The below content is taken from http://unused-css.com/ so credit to them for recommending other solutions:

Latish Sehgal has written a windows application to find and remove unused CSS classes. I haven't tested it but from the description, you have to provide the path of your html files and one CSS file. The program will then list the unused CSS selectors. From the screenshot, it looks like there is no way to export this list or download a new clean CSS file. It also looks like the service is limited to one CSS file. If you have multiple files you want to clean, you have to clean them one by one.

Dust-Me Selectors is a Firefox extension (for v1.5 or later) that finds unused CSS selectors. It extracts all the selectors from all the stylesheets on the page you're viewing, then analyzes that page to see which of those selectors are not used. The data is then stored so that when testing subsequent pages, selectors can be crossed off the list as they're encountered. This tool is supposed to be able to spider a whole website but I unfortunately could make it work. Also, I don't believe you can configure and download the CSS file with the styles removed.

Topstyle is a windows application including a bunch of tools to edit CSS. I haven't tested it much but it looks like it has the ability to removed unused CSS selectors. This software costs 80 USD.

Liquidcity CSS cleaner is a php script that uses regular expressions to check the styles of one page. It will tell you the classes that aren't available in the HTML code. I haven't tested this solution.

Deadweight is a CSS coverage tool. Given a set of stylesheets and a set of URLs, it determines which selectors are actually used and lists which can be "safely" deleted. This tool is a ruby module and will only work with rails website. The unused selectors have to be manually removed from the CSS file.

Helium CSS is a javascript tool for discovering unused CSS across many pages on a web site. You first have to install the javascript file to the page you want to test. Then, you have to call a helium function to start the cleaning.

UnusedCSS.com is web application with an easy to use interface. Type the url of a site and you will get a list of CSS selectors. For each selector, a number indicates how many times a selector is used. This service has a few limitations. The @import statement is not supported. You can't configure and download the new clean CSS file.

CSSESS is a bookmarklet that helps you find unused CSS selectors on any site. This tool is pretty easy to use but it won't let you configure and download clean CSS files. It will only list unused CSS files.

the only coding guidelines I've seen suggested for this is to put fields at the top of the class definition.

i tend to put constructors next.

my general comment would be that you should stick to one class per file and if the class is big enough that the organization of properties versus methods is a big concern, how big is the class and should you be refactoring it anyway? does it represent multiple concerns?

To detect your controller is pushed or not just use below code in anywhere you want:

if ([[[self.parentViewController childViewControllers] firstObject] isKindOfClass:[self class]]) {

    // Not pushed
}
else {

    // Pushed
}

I hope this code can help anyone...

after i tried the given answers, i found out another reason for the same Exception, that i had to add the library i'm using manually to my main library through

Right click on my main library > 
Properties > 
Android > 
Go to the very bottom of the screen and click (Add) > 
Select my other library that caused the crash >
Apply

before this solution, i used the "Fix Project setup" from within the .java file in eclipse, but this did not work, so i had to add it manually here and it worked

What they said, except find $PWD or (in bash) find ~+ is a bit more convenient.

More Suggestive answer supporting rmaddy's answer as our primary purpose is to delete unnecessary file and folder:

1. Delete this folder after every few days interval. Most of the time, it occupy huge space!

     ~/Library/Developer/Xcode/DerivedData
   

2. All your targets are kept in the archived form in Archives folder. Before you decide to delete contents of this folder, here is a warning - if you want to be able to debug deployed versions of your App, you shouldn’t delete the archives. Xcode will manage of archives and creates new file when new build is archived.

     ~/Library/Developer/Xcode/Archives
   

3. iOS Device Support folder creates a subfolder with the device version as an identifier when you attach the device. Most of the time it’s just old stuff. Keep the latest version and rest of them can be deleted (if you don’t have an app that runs on 5.1.1, there’s no reason to keep the 5.1.1 directory/directories). If you really don't need these, delete. But we should keep a few although we test app from device mostly.

   ~/Library/Developer/Xcode/iOS DeviceSupport
   

4. Core Simulator folder is familiar for many Xcode users. It’s simulator’s territory; that's where it stores app data. It’s obvious that you can toss the older version simulator folder/folders if you no longer support your apps for those versions. As it is user data, no big issue if you delete it completely but it’s safer to use ‘Reset Content and Settings’ option from the menu to delete all of your app data in a Simulator.

     ~/Library/Developer/CoreSimulator 
   

(Here's a handy shell command for step 5: xcrun simctl delete unavailable )

5. Caches are always safe to delete since they will be recreated as necessary. This isn’t a directory; it’s a file of kind Xcode Project. Delete away!

   ~/Library/Caches/com.apple.dt.Xcode
   

6. Additionally, Apple iOS device automatically syncs specific files and settings to your Mac every time they are connected to your Mac machine. To be on safe side, it’s wise to use Devices pane of iTunes preferences to delete older backups; you should be retaining your most recent back-ups off course.

    ~/Library/Application Support/MobileSync/Backup

I got back about 40GB!

You can also use TempVars - note '!' syntax is essential

Public - means that the class (program) is available for use by any other class.

Static - creates a class. Can also be applied to variables and methods,making them class methods/variables instead of just local to a particular instance of the class.

Void - this means that no product is returned when the class completes processing. Compare this with helper classes that provide a return value to the main class,these operate like functions; these do not have void in the declaration.

You can use a utility function I've created for the purpose of running code in the page context and getting back the returned value.

This is done by serializing a function to a string and injecting it to the web page.

The utility is available here on GitHub.

Usage examples -

// Some code that exists only in the page context -
window.someProperty = 'property';
function someFunction(name = 'test') {
    return new Promise(res => setTimeout(()=>res('resolved ' + name), 1200));
}
/////////////////

// Content script examples -

await runInPageContext(() => someProperty); // returns 'property'

await runInPageContext(() => someFunction()); // returns 'resolved test'

await runInPageContext(async (name) => someFunction(name), 'with name' ); // 'resolved with name'

await runInPageContext(async (...args) => someFunction(...args), 'with spread operator and rest parameters' ); // returns 'resolved with spread operator and rest parameters'

await runInPageContext({
    func: (name) => someFunction(name),
    args: ['with params object'],
    doc: document,
    timeout: 10000
} ); // returns 'resolved with params object'

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).

You have a few options here. The simplest is to chain your collectors:

Map<String, Map<Integer, List<Person>>> map = people
    .collect(Collectors.groupingBy(Person::getName,
        Collectors.groupingBy(Person::getAge));

Then to get a list of 18 year old people called Fred you would use:

map.get("Fred").get(18);

A second option is to define a class that represents the grouping. This can be inside Person. This code uses a record but it could just as easily be a class (with equals and hashCode defined) in versions of Java before JEP 359 was added:

class Person {
    record NameAge(String name, int age) { }

    public NameAge getNameAge() {
        return new NameAge(name, age);
    }
}

Then you can use:

Map<NameAge, List<Person>> map = people.collect(Collectors.groupingBy(Person::getNameAge));

and search with

map.get(new NameAge("Fred", 18));

Finally if you don't want to implement your own group record then many of the Java frameworks around have a pair class designed for this type of thing. For example: apache commons pair If you use one of these libraries then you can make the key to the map a pair of the name and age:

Map<Pair<String, Integer>, List<Person>> map =
    people.collect(Collectors.groupingBy(p -> Pair.of(p.getName(), p.getAge())));

and retrieve with:

map.get(Pair.of("Fred", 18));

Personally I don't really see much value in generic tuples now that records are available in the language as records display intent better and require very little code.

You have many options. Collating some of the answers above and the accepted answer from this post you can do:
1. df[-df["column"].isin(["value"])]
2. df[~df["column"].isin(["value"])]
3. df[df["column"].isin(["value"]) == False]
4. df[np.logical_not(df["column"].isin(["value"]))]

Note: for option 4 for you'll need to import numpy as np

Update: You can also use the .query method for this too. This allows for method chaining:
5. df.query("column not in @values").
where values is a list of the values that you don't want to include.

In case this may be helpful for someone who just needs to show colors rather than output, as a hackish workaround (and FYI), since GitHub supports Unicode (as Unicode, numeric character references or HTML entities), you could try colored Unicode symbols, though it depends on the font rendering them in color (as it happens to be appearing for me on Windows 10 and Mac 10.12.5, at least, though on the Mac at least, the up/down-pointing small red triangles don't show in red):

• RED APPLE (🍎):
• GREEN APPLE (🍏):
• BLUE HEART (💙):
• GREEN HEART (💚):
• YELLOW HEART (💛):
• PURPLE HEART (💜):
• GREEN BOOK (📗):
• BLUE BOOK (📘):
• ORANGE BOOK (📙):
• LARGE RED CIRCLE (🔴):
• LARGE BLUE CIRCLE (🔵):
• LARGE ORANGE DIAMOND (🔶):
• LARGE BLUE DIAMOND (🔷):
• SMALL ORANGE DIAMOND (🔸):
• SMALL BLUE DIAMOND (🔹):
• UP-POINTING RED TRIANGLE (🔺):
• DOWN-POINTING RED TRIANGLE (🔻):
• UP-POINTING SMALL RED TRIANGLE (🔼):
• DOWN-POINTING SMALL RED TRIANGLE (🔽):

In Ubuntu, you need to uncomment this line in file php.ini which is located at /etc/php/7.0/apache2/php.ini:

extension=php_mysqli.so

Using plyr package:

library(plyr)

count(mydf$V1)

It will return you a frequency of each value.

A backslash needs to be escaped with another backslash.

print('\\')

If you want search for printable strings, you can use:

strings -ao filename | grep string

strings will output all printable strings from a binary with offsets, and grep will search within.

If you want search for any binary string, here is your friend:

There are a few operations you can only do with DI/SI (or their extended counterparts, if you didn't learn ASM in 1985). Among these are

REP STOSB
REP MOVSB
REP SCASB

Which are, respectively, operations for repeated (= mass) storing, loading and scanning. What you do is you set up SI and/or DI to point at one or both operands, perhaps put a count in CX and then let 'er rip. These are operations that work on a bunch of bytes at a time, and they kind of put the CPU in automatic. Because you're not explicitly coding loops, they do their thing more efficiently (usually) than a hand-coded loop.

Just in case you're wondering: Depending on how you set the operation up, repeated storing can be something simple like punching the value 0 into a large contiguous block of memory; MOVSB is used, I think, to copy data from one buffer (well, any bunch of bytes) to another; and SCASB is used to look for a byte that matches some search criterion (I'm not sure if it's only searching on equality, or what – you can look it up :) )

That's most of what those regs are for.

I figured it this way:

* { padding: 0; margin: 0 }
body { height: 100%; white-space: nowrap }
html { height: 100% }

.red { background: red }
.blue { background: blue }
.yellow { background: yellow }

.header { width: 100%; height: 10%; position: fixed }
.wrapper { width: 1000%; height: 100%; background: green }
.page { width: 10%; height: 100%; float: left }

<div class="header red"></div>
<div class="wrapper">
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
</div>

I have the wrapper at 1000% and ten pages at 10% each. I set mine up to still have "pages" with each being 100% of the window (color coded). You can do eight pages with an 800% wrapper. I guess you can leave out the colors and have on continues page. I also set up a fixed header, but that's not necessary. Hope this helps.

I would have commented on whizzle's answer if I could, but thought it useful to note that in order for me to solve this problem in the context of multi-window mode in Android N, I needed to change the code slightly to this:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if(MeasureSpec.getSize(heightMeasureSpec) > maxHeight) {
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST);
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

This allows for the layout to resize to be smaller than the max height, but also prevent it from being larger than the max height. I used this is a layout class that Overrides RelativeLayout and this allowed me to create a custom dialog with a ScrollView as the child of MaxHeightRelativeLayout that does not expand the full height of the screen and also shrinks to fit within the smallest widow size in multi-window for Android N.

Old way (if you don't now the length of arguments/parameters)

 >> function sumla1(){

    result=0
    for(let i=0; i<arguments.length;i++){

        result+=arguments[i];

    }
    return result;
    }
    >> sumla1(45,67,88);
    >> 200

ES6 (destructuring of array)

>> function sumla2(...x){return x.reduce((a,b)=>a+b)}
>>
>> sumla2(5,5,6,7,8)
>>
>> 31
>>
>> var numbers = [4, 9, 16, 25];
>> sumla2(...numbers);
>> 54

Both of the examples immediately above didn't work for me. Opening a recordset on the table and adding a record does work to add the record, except:

myLong = CLng(rs!AutoNumberField)

returns Null if put between rs.AddNew and rs.Update. If put after rs.Update, it does return something, but it's always wrong, and always the same incorrect value. Looking at the table directly after adding the new record shows an autonumber field value different than the one returned by the above statement.

myLong = DLookup("AutoNumberField","TableName","SomeCriteria")

will work properly, as long as it's done after rs.Update, and there are any other fields which can uniquely identify the record.

There are no difference between ProcessBuilder.start() and Runtime.exec() because implementation of Runtime.exec() is:

public Process exec(String command) throws IOException {
    return exec(command, null, null);
}

public Process exec(String command, String[] envp, File dir)
    throws IOException {
    if (command.length() == 0)
        throw new IllegalArgumentException("Empty command");

    StringTokenizer st = new StringTokenizer(command);
    String[] cmdarray = new String[st.countTokens()];
    for (int i = 0; st.hasMoreTokens(); i++)
        cmdarray[i] = st.nextToken();
    return exec(cmdarray, envp, dir);
}

public Process exec(String[] cmdarray, String[] envp, File dir)
    throws IOException {
    return new ProcessBuilder(cmdarray)
        .environment(envp)
        .directory(dir)
        .start();
}

So code:

List<String> list = new ArrayList<>();
new StringTokenizer(command)
.asIterator()
.forEachRemaining(str -> list.add((String) str));
new ProcessBuilder(String[])list.toArray())
            .environment(envp)
            .directory(dir)
            .start();

should be the same as:

Runtime.exec(command)

Every performance problem with PyCharm is unique, a solution that helps to one person will not work for another. The only proper way to fix your specific performance problem is by capturing the CPU profiler snapshot as described in this document and sending it to PyCharm support team, either by submitting a ticket or directly into the issue tracker.

After the CPU snapshot is analyzed, PyCharm team will work on a fix and release a new version which will (hopefully) not be affected by this specific performance problem. The team may also suggest you some configuration change or workaround to remedy the problem based on the analysis of the provided data.

All the other "solutions" (like enabling Power Save mode and changing the highlighting level) will just hide the real problems that should be fixed.

Use this:

SELECT 
    Pieces, Price, 
    Pieces * Price as 'Total' 
FROM myTable

Push object into your array. Try this:

export class FormComponent implements OnInit {
    name: string;
    empoloyeeID : number;
    empList: Array<{name: string, empoloyeeID: number}> = []; 
    constructor() {}
    ngOnInit() {}
    onEmpCreate(){
        console.log(this.name,this.empoloyeeID);
        this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
        this.name = "";
        this.empoloyeeID = 0;
    }
}

The following works for me:

public virtual void Send(string fileName, byte[] file)
{
    ByteArrayToFile(fileName, file);

    var request = (FtpWebRequest) WebRequest.Create(new Uri(ServerUrl + fileName));

    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UsePassive = false;
    request.Credentials = new NetworkCredential(UserName, Password);
    request.ContentLength = file.Length;

    var requestStream = request.GetRequestStream();
    requestStream.Write(file, 0, file.Length);
    requestStream.Close();

    var response = (FtpWebResponse) request.GetResponse();

    if (response != null)
        response.Close();
}

You can't read send the file parameter in your code as it is only the filename.

Use the following:

byte[] bytes = File.ReadAllBytes(dir + file);

To get the file so you can pass it to the Send method.

Check my fiddle from this thread: Draw a line connecting two clicked div columns

The layout is different, but basically the idea is to create invisible divs between the boxes and add corresponding borders with jQuery (the answer is only HTML and CSS)

In Xcode, check the "Requires Full Screen" checkbox under General > Targets, as shown below.

Long, and could maybe be shortened. Supports special characters ?"-_.

\A(?=[-\?\"_a-zA-Z0-9]*?[A-Z])(?=[-\?\"_a-zA-Z0-9]*?[a-z])(?=[-\?\"_a-zA-Z0-9]*?[0-9])[-\?\"_a-zA-Z0-9]{8,15}\z

Query :- Select datename(m,GETDATE())+'-'+cast(datepart(yyyy,GETDATE()) as varchar) as FieldName

Output :- January-2019

general datefield we can use

datename(m,<DateField>)+' '+cast(datepart(yyyy,<DateField>) as varchar) as FieldName

For me there was a lack of space on my drive (around 1gb free). Cleared away a few things and it loaded up fine.

Microsoft has a tool just for this purpose: Microsoft Expression Web. There's a free version with a bunch of FrontPage/Dreamweaver-like garbage that nobody wants. What's important is that it has a great browser testing feature. I'm running Windows 8.1 Pro (final release, not preview) with Internet Explorer 11. I get these local browsers:

• Internet Explorer 6
• Internet Explorer 7
• Internet Explorer 11 /!\ Unsupported Version (can't use it; big whoop, I have the browser)

Then I get a Remote Browsers (Beta) option. I'm supposed to sign up with a valid e-mail, but there's an error communicating with the server. Oh well.

Firefox used to be supported, but I don't see it now. Might be hiding.

I can compare side-by-side between browser versions. I can also compare with an image, or apparently, a PSD file (no idea how well that works). InDesign would be nice, but that's probably asking for too much.

I have the full version of Expression partially installed as well due to Visual Studio Ultimate being on the same computer, so I'd appreciate someone confirming in a comment that my free installation isn't automatically upgrading.

Update: Looks like the online service was discontinued, but local browsers are still supported. You can also download just SuperPreview, without the editor garbage. If you want the full IDE, the latest version is Microsoft Expression Web 4 (Free Version). Here's the official list of supported browsers. IE6 seems to give an error on Windows 8.1, but IE7 works.

Update 2014-12-09: Microsoft has pretty much given up on this. Don't expect it to work well.

React behavior

Apart from the rest of the answers, I would like to show one difference in React.

If I throw a new Error() and I am in development mode, I will get an error screen and a console log. If I throw a string literal, I will only see it in the console and possibly miss it, if I am not watching the console log.

Example

Throwing an error logs into the console and shows an error screen while in development mode (the screen won't be visible in production).

throw new Error("The application could not authenticate.");

Whereas the following code only logs into the console:

throw "The application could not authenticate.";

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

One way of achieving this is to make your class implement OnClickListener and then add it to your buttons like this:

Example:

//make your class implement OnClickListener
public class MyClass implements OnClickListener{

        ...

        //Create your buttons and set their onClickListener to "this"
        Button b1 = (Button) findViewById(R.id.buttonplay);   
        b1.setOnClickListener(this);

        Button b2 = (Button) findViewById(R.id.buttonstop);   
        b2.setOnClickListener(this);

        ...

        //implement the onClick method here
        public void onClick(View v) {
           // Perform action on click
          switch(v.getId()) {
            case R.id.buttonplay:
              //Play voicefile
              MediaPlayer.create(getBaseContext(), R.raw.voicefile).start();
              break;
            case R.id.buttonstop:
              //Stop MediaPlayer
              MediaPlayer.create(getBaseContext(), R.raw.voicefile).stop();
              break;
          }
       }
}

I store my data this way:

accountsTable ->
  key1 -> account1
  key2 -> account2

in order to get object data:

accountsDb = mDatabase.child("accountsTable");

accountsDb.child("some   key").addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot snapshot) {

                    try{

                        Account account  = snapshot.getChildren().iterator().next()
                                  .getValue(Account.class);


                    } catch (Throwable e) {
                        MyLogger.error(this, "onCreate eror", e);
                    }
                }
                @Override public void onCancelled(DatabaseError error) { }
            });

you can use group and max:

db.getCollection('kids').aggregate([
    {
        $group: {
            _id: null,
            maxQuantity: {$max: "$age"}
        }
    }
])

.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

try:

.table-hover > tbody > tr.active:hover > th {
                background-color: #color;
            }

Try innerText property:

var content = document.getElementById("one").innerText;
alert(content);

See also this fiddle http://fiddle.jshell.net/4g8vb/

For normal form you can do

class MyModelForm(forms.ModelForm):
    slug = forms.CharField(widget=forms.HiddenInput())

If you have model form you can do the following

class MyModelForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        fields = ('slug', 'ext')
        widgets = {'slug': forms.HiddenInput()}

You can also override __init__ method

class Myform(forms.Form):
    def __init__(self, *args, **kwargs):
        super(Myform, self).__init__(*args, **kwargs)
        self.fields['slug'].widget = forms.HiddenInput()

The date function would be defined something like this:

function date($format, $timestamp = null)
{
    if ($timestamp === null) {
        $timestamp = time();
    }

    // Format the timestamp according to $format
}

Usually, you would put the default value like this:

function foo($required, $optional = 42)
{
    // This function can be passed one or more arguments
}

However, only literals are valid default arguments, which is why I used null as default argument in the first example, not $timestamp = time(), and combined it with a null check. Literals include arrays (array() or []), booleans, numbers, strings, and null.

You could also use jquery when and then functions. for example

 $.when( $.ajax( "test.aspx" ) ).then(function( data, textStatus, jqXHR ) {
  //another ajax call
});

https://api.jquery.com/jQuery.when/

In oficial documentation https://github.com/mde/ejs#includes show that includes works like that:

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

If you happen to have AWS S3 that works like a charm also. Well. Relatively speaking :-)

Create a bucket for your ad hocs in AWS, add an index file (it can just be a blank index.html file) then using a client that can connect to S3 like CyberDuck or Coda (I used Coda - where you'd select Add Site to get a connection window) then set the connections like the attached:

Then build your enterprise ad hoc in XCode and make sure you use https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.ipa as the Application URL, and upload it to your new S3 bucket directory.

Your itms link should match, i.e. itms-services://?action=download-manifest&url=https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.plist

And voilá.

This is only for generic AWS URLs - I haven't tried with custom URLs on AWS so you might have to do a few things differently.

I was determined to try to make James Webster's solution above work, but I couldn't get it to work with Plesk.

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:

$("document").ready(function() {
    setTimeout(function() {
        $("ul.galleria li:first-child img").trigger('click');
    },10);
});

A delay of 10ms will cause the function to run immediately after all the $(document).ready() handlers have been called.

OR you check if the element is ready:

$("document").ready(function() {
  $("ul.galleria li:first-child img").ready(function() {
    $(this).click();
  });    
});

Easily achieved with the css property user-select set to all. Like this:

div.anyClass {_x000D_
  user-select: all;_x000D_
}

The XMLHttpRequest.timeout property represents a number of milliseconds a request can take before automatically being terminated. The default value is 0, which means there is no timeout. An important note the timeout shouldn't be used for synchronous XMLHttpRequests requests, used in a document environment or it will throw an InvalidAccessError exception. You may not use a timeout for synchronous requests with an owning window.

IE10 and 11 do not support synchronous requests, with support being phased out in other browsers too. This is due to detrimental effects resulting from making them.

I am having a similar problem. I can get the screen to stay on, but if I use a partial wake lock and the screen is turned off, my onFinish function isn't called until the screen is turned on.

You can check your wake lock using mWakeLock.isHeld(), first of all, to make sure you're getting it. Easiest way is to add that to the code, set a breakpoint on it in the debugger, and then check it.

In my case, I'm getting it, but the partial wake lock doesn't seem to be doing anything. Here's my working code for the screen dim lock.

protected void setScreenLock(boolean on){
        if(mWakeLock == null){
            PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
            mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK |
                                        PowerManager.ON_AFTER_RELEASE, TAG);
        }
        if(on){
         mWakeLock.acquire();
        }else{
            if(mWakeLock.isHeld()){
                mWakeLock.release();
            }
         mWakeLock = null;
        }

    }

ADDENDUM:

Droid Eris and DROID users are reporting to me that this DOES NOT work on their devices, though it works fine on my G1. What device are you testing on? I think this may be an Android bug.

In c++11, you can use std::regex_replace:

#include <string>
#include <regex>

std::string test = "abc def abc def";
test = std::regex_replace(test, std::regex("def"), "klm");

Fairly straightforward (in compared to how it was done with the previous API).

Source from (copy and pasted) the Angular official guide

 http
  .get<ItemsResponse>('/api/items')
  .subscribe(
    // Successful responses call the first callback.
    data => {...},
    // Errors will call this callback instead:
    err => {
      console.log('Something went wrong!');
    }
  );

The problem is, you are creating a transport object and using it's connect method to authenticate yourself. But then you use a static method to send the message which ignores authentication done by the object.

So, you should either use the sendMessage(message, message.getAllRecipients()) method on the object or use an authenticator as suggested by others to get authorize through the session.

Here's the Java Mail FAQ, you need to read.

It does seem a little cumbersome to ignore files (and folders) in Team Foundation Server. I've found a couple ways to do this (using TFS / Team Explorer / Visual Studio 2008). These methods work with the web site ASP project type, too.

One way is to add a new or existing item to a project (e.g. right click on project, Add Existing Item or drag and drop from Windows explorer into the solution explorer), let TFS process the file(s) or folder, then undo pending changes on the item(s). TFS will unmark them as having a pending add change, and the files will sit quietly in the project and stay out of TFS.

Another way is with the Add Items to Folder command of Source Control Explorer. This launches a small wizard, and on one of the steps you can select items to exclude (although, I think you have to add at least one item to TFS with this method for the wizard to let you continue).

You can even add a forbidden patterns check-in policy (under Team -> Team Project Settings -> Source Control... -> Check-in Policy) to disallow other people on the team from mistakenly checking in certain assets.

Here is the Best and shortest solution that works for me as of may, 2018 for Laravel 5.5

1. just cut your .htaccess file from the /public directory to the root directory and replace it content with the following code:

   <IfModule mod_rewrite.c>
       <IfModule mod_negotiation.c>
          Options -MultiViews
       </IfModule>
   
       RewriteEngine On
   
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteRule ^(.*)/$ /$1 [L,R=301]
   
       RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^ server.php [L]
   
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteCond %{REQUEST_URI} !^/public/
       RewriteRule ^(css|js|images)/(.*)$ public/$1/$2 [L,NC]
   </IfModule>
   

2. Just save the .htaccess file and that is all.

3. Rename your server.php file to index.php. that is all enjoy!

I had a similar issue with an integer that could be legitimately assigned 0 in Access VBA. None of the above solutions worked for me.

At first I just used a boolean var and IF statement:

Dim i as integer, bol as boolean
   If bol = false then
      i = ValueIWantToAssign
      bol = True
   End If

In my case, my integer variable assignment was within a for loop and another IF statement, so I ended up using "Exit For" instead as it was more concise.

Like so:

Dim i as integer
ForLoopStart
   If ConditionIsMet Then
      i = ValueIWantToAssign
   Exit For
   End If
ForLoopEnd

For people who are still getting error despite of passing absolute path, should check that if file has a valid name. For me I was trying to create a file with '/' in the file name. As soon as I removed '/', I was able to create the file.

The following should work

.carousel .item {
  height: 300px;
}

.item img {
    position: absolute;
    top: 0;
    left: 0;
    min-height: 300px;
}

JSFille for reference.

It's empty by default. You'll find a bunch of settings in /etc/apache2/apache2.conf.

In there it does this:

# Include all the user configurations:
Include httpd.conf

The answer by ganeshragav is correct, but it is also useful to know that you can use:

firewall-cmd --permanent --zone=public --add-port=2888/tcp 

but if is a known service, you can use:

firewall-cmd --permanent --zone=public --add-service=http 

and then reload the firewall

firewall-cmd --reload

[ Answer modified to reflect Martin Peter's comment, original answer had --permanent at end of command line ]

Object does not have forEach, it belongs to Array prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:

Object.keys(a).forEach(function (key){
    console.log(a[key]);
});

Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};, Object.keys(v) gives you an array of the keys so you get ["cat","dog","bird"]

On a Windows machine run the python command prompt as administrator. That should resolved the permissions issue when creating a new python 3 notebook.

I know this question already have been answer but I have made some update to the GD function :

  ### COST FUNCTION

def cost(theta,X,y):
     ### Evaluate half MSE (Mean square error)
     m = len(y)
     error = np.dot(X,theta) - y
     J = np.sum(error ** 2)/(2*m)
     return J

 cost(theta,X,y)



def GD(X,y,theta,alpha):

    cost_histo = [0]
    theta_histo = [0]

    # an arbitrary gradient, to pass the initial while() check
    delta = [np.repeat(1,len(X))]
    # Initial theta
    old_cost = cost(theta,X,y)

    while (np.max(np.abs(delta)) > 1e-6):
        error = np.dot(X,theta) - y
        delta = np.dot(np.transpose(X),error)/len(y)
        trial_theta = theta - alpha * delta
        trial_cost = cost(trial_theta,X,y)
        while (trial_cost >= old_cost):
            trial_theta = (theta +trial_theta)/2
            trial_cost = cost(trial_theta,X,y)
            cost_histo = cost_histo + trial_cost
            theta_histo = theta_histo +  trial_theta
        old_cost = trial_cost
        theta = trial_theta
    Intercept = theta[0] 
    Slope = theta[1]  
    return [Intercept,Slope]

res = GD(X,y,theta,alpha)

This function reduce the alpha over the iteration making the function too converge faster see Estimating linear regression with Gradient Descent (Steepest Descent) for an example in R. I apply the same logic but in Python.

one solution could be to find a way of pulling the numbers from the string and placing them in a column of just numbers the using the =MEDIAN() function giving the new number column as the range

Bear in mind that using WaitForSingleObject can get you into trouble in this scenario. The following is snipped from a tip on my website:

The problem arises because your application has a window but isn't pumping messages. If the spawned application invokes SendMessage with one of the broadcast targets (HWND_BROADCAST or HWND_TOPMOST), then the SendMessage won't return to the new application until all applications have handled the message - but your app can't handle the message because it isn't pumping messages.... so the new app locks up, so your wait never succeeds.... DEADLOCK.

If you have absolute control over the spawned application, then there are measures you can take, such as using SendMessageTimeout rather than SendMessage (e.g. for DDE initiations, if anybody is still using that). But there are situations which cause implicit SendMessage broadcasts over which you have no control, such as using the SetSysColors API for instance.

The only safe ways round this are:

1. split off the Wait into a separate thread, or
2. use a timeout on the Wait and use PeekMessage in your Wait loop to ensure that you pump messages, or
3. use the MsgWaitForMultipleObjects API.

Lookarounds are zero width assertions. They check for a regex (towards right or left of the current position - based on ahead or behind), succeeds or fails when a match is found (based on if it is positive or negative) and discards the matched portion. They don't consume any character - the matching for regex following them (if any), will start at the same cursor position.

Read regular-expression.info for more details.

• Positive lookahead:

Syntax:

(?=REGEX_1)REGEX_2

Match only if REGEX_1 matches; after matching REGEX_1, the match is discarded and searching for REGEX_2 starts at the same position.

example:

(?=[a-z0-9]{4}$)[a-z]{1,2}[0-9]{2,3}

REGEX_1 is [a-z0-9]{4}$ which matches four alphanumeric chars followed by end of line.
REGEX_2 is [a-z]{1,2}[0-9]{2,3} which matches one or two letters followed by two or three digits.

REGEX_1 makes sure that the length of string is indeed 4, but doesn't consume any characters so that search for REGEX_2 starts at the same location. Now REGEX_2 makes sure that the string matches some other rules. Without look-ahead it would match strings of length three or five.

• Negative lookahead

Syntax:

(?!REGEX_1)REGEX_2

Match only if REGEX_1 does not match; after checking REGEX_1, the search for REGEX_2 starts at the same position.

example:

(?!.*\bFWORD\b)\w{10,30}$

The look-ahead part checks for the FWORD in the string and fails if it finds it. If it doesn't find FWORD, the look-ahead succeeds and the following part verifies that the string's length is between 10 and 30 and that it contains only word characters a-zA-Z0-9_

Look-behind is similar to look-ahead: it just looks behind the current cursor position. Some regex flavors like javascript doesn't support look-behind assertions. And most flavors that support it (PHP, Python etc) require that look-behind portion to have a fixed length.

• Atomic groups basically discards/forgets the subsequent tokens in the group once a token matches. Check this page for examples of atomic groups

Apart from the above answers, we can use asn1parse to get the values

$ openssl asn1parse -i -in pub0.der -inform DER -offset 24
0:d=0  hl=4 l= 266 cons: SEQUENCE
4:d=1  hl=4 l= 257 prim:  INTEGER           :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
265:d=1  hl=2 l= 3 prim:  INTEGER           :010001

Now, to get to this offset,we try the default asn1parse

$ openssl asn1parse -i -in pub0.der -inform DER
 0:d=0  hl=4 l= 290 cons: SEQUENCE
 4:d=1  hl=2 l=  13 cons:  SEQUENCE
 6:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
17:d=2  hl=2 l=   0 prim:   NULL
19:d=1  hl=4 l= 271 prim:  BIT STRING

We need to get to the BIT String part, so we add the sizes

depth_0_header(4) + depth_1_full_size(2 + 13) + Container_1_EOC_bit + BIT_STRING_header(4) = 24

This can be better visialized at: ASN.1 Parser, if you hover at tags, you will see the offsets

1 Direct Execution / Conversion

Use from to directly convert a previously created Promise to an Observable.

import { from } from 'rxjs';

// getPromise() is called once, the promise is passed to the Observable
const observable$ = from(getPromise());

observable$ will be a hot Observable that effectively replays the Promises value to Subscribers.

It's a hot Observable because the producer (in this case the Promise) is created outside of the Observable. Multiple subscribers will share the same Promise. If the inner Promise has been resolved a new subscriber to the Observable will get its value immediately.

2 Deferred Execution On Every Subscribe

Use defer with a Promise factory function as input to defer the creation and conversion of a Promise to an Observable.

import { defer } from 'rxjs';

// getPromise() is called every time someone subscribes to the observable$
const observable$ = defer(() => getPromise());

observable$ will be a cold Observable.

It's a cold Observable because the producer (the Promise) is created inside of the Observable. Each subscriber will create a new Promise by calling the given Promise factory function.

This allows you to create an observable$ without creating and thus executing a Promise right away and without sharing this Promise with multiple subscribers. Each subscriber to observable$ effectively calls from(promiseFactory()).subscribe(subscriber). So each subscriber creates and converts its own new Promise to a new Observable and attaches itself to this new Observable.

3 Many Operators Accept Promises Directly

Most RxJS operators that combine (e.g. merge, concat, forkJoin, combineLatest ...) or transform observables (e.g. switchMap, mergeMap, concatMap, catchError ...) accept promises directly. If you're using one of them anyway you don't have to use from to wrap a promise first (but to create a cold observable you still might have to use defer).

// Execute two promises simultaneously
forkJoin(getPromise(1), getPromise(2)).pipe(
  switchMap(([v1, v2]) => v1.getPromise(v2)) // map to nested Promise
)

Check the documentation or implementation to see if the operator you're using accepts ObservableInput or SubscribableOrPromise.

type ObservableInput<T> = SubscribableOrPromise<T> | ArrayLike<T> | Iterable<T>;
// Note the PromiseLike ----------------------------------------------------v
type SubscribableOrPromise<T> = Subscribable<T> | Subscribable<never> | PromiseLike<T> | InteropObservable<T>;

The difference between from and defer in an example: https://stackblitz.com/edit/rxjs-6rb7vf

const getPromise = val => new Promise(resolve => {
  console.log('Promise created for', val);
  setTimeout(() => resolve(`Promise Resolved: ${val}`), 5000);
});

// the execution of getPromise('FROM') starts here, when you create the promise inside from
const fromPromise$ = from(getPromise('FROM'));
const deferPromise$ = defer(() => getPromise('DEFER'));

fromPromise$.subscribe(console.log);
// the execution of getPromise('DEFER') starts here, when you subscribe to deferPromise$
deferPromise$.subscribe(console.log);

Another way to convert.

If you have string field, you can transform it or its numerical part the following way: add leading zeros to make all integer strings having equal length.

ORDER BY CONCAT( REPEAT(  "0", 18 - LENGTH( stringfield ) ) , stringfield ) 

or order by part of a field something like 'tensymbols13', 'tensymbols1222' etc.

ORDER BY CONCAT( REPEAT(  "0", 18 - LENGTH( LEFT( stringfield , 10 ) ) ) , LEFT( stringfield , 10 ) ) 

I found the easiest way was to:

1. Convert the samples column into a DataFrame
2. Joining with the original df
3. Melting

Shown here:

    df.samples.apply(lambda x: pd.Series(x)).join(df).\
melt(['subject','trial_num'],[0,1,2],var_name='sample')

        subject  trial_num sample  value
    0         1          1      0  -0.24
    1         1          2      0   0.14
    2         1          3      0  -0.67
    3         2          1      0  -1.52
    4         2          2      0  -0.00
    5         2          3      0  -1.73
    6         1          1      1  -0.70
    7         1          2      1  -0.70
    8         1          3      1  -0.29
    9         2          1      1  -0.70
    10        2          2      1  -0.72
    11        2          3      1   1.30
    12        1          1      2  -0.55
    13        1          2      2   0.10
    14        1          3      2  -0.44
    15        2          1      2   0.13
    16        2          2      2  -1.44
    17        2          3      2   0.73

It's worth noting that this may have only worked because each trial has the same number of samples (3). Something more clever may be necessary for trials of different sample sizes.

You may try this code for you to take comma separated values / an array of values to get back a JSON from webAPI

 public class CategoryController : ApiController
 {
     public List<Category> Get(String categoryIDs)
     {
         List<Category> categoryRepo = new List<Category>();

         String[] idRepo = categoryIDs.Split(',');

         foreach (var id in idRepo)
         {
             categoryRepo.Add(new Category()
             {
                 CategoryID = id,
                 CategoryName = String.Format("Category_{0}", id)
             });
         }
         return categoryRepo;
     }
 }

 public class Category
 {
     public String CategoryID { get; set; }
     public String CategoryName { get; set; }
 } 

Output :

[
{"CategoryID":"4","CategoryName":"Category_4"}, 
{"CategoryID":"5","CategoryName":"Category_5"}, 
{"CategoryID":"3","CategoryName":"Category_3"} 
]

After declaring the base url in config.php, (note, if you are still getting the same error, check autoload.php)

$config['base_url'] = "http://somesite.com/somedir/";

Check "autoload"

CodeIgniter file structure:

\application\config\autoload.php

And enable on autoload:

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

And it works.

This was what fixed it for me. (I had already tried toggling the capabilities on/off, recreating the provisioning profile, etc).

In the Build Settings tab, in Code Signing Entitlements, my .entitlements file wasn't link for all sections. Once I added it to the Any SDK section, the error was resolved.

When i faced such a situation, i have done something like this:

Logger = {
    info: function (message, tag) {
        var fullMessage = '';        
        fullMessage = this._getFormatedMessage(message, tag);
        if (loggerEnabled) {
            console.log(fullMessage);
        }
    },
    warning: function (message, tag) {
        var fullMessage = '';
        fullMessage = this._getFormatedMessage(message, tag);
        if (loggerEnabled) {
            console.warn(fullMessage);`enter code here`
        }
    },
    _getFormatedMessage: function () {}
};

so now i can call the info method as Logger.info("my Msg", "Tag");

Specify the Class Card for the constructor-:

void Card::Card(Card::Rank rank, Card::Suit suit) {

And also define the default constructor and destructor.

One way to do it is to set the index to be auto incrementing. Then your SQL statement simply specifies NULL and then SQL parser does the rest for you.

INSERT INTO foo VALUES (null);

don't have to chain so many tools. Just one awk command does the job

 COMPANY_NAME=$(awk -F"=" '/company_name/{gsub(/;$/,"",$2) ;print $2}' file.txt)

Session state is saved on the server, ViewState is saved in the page.

Session state is usually cleared after a period of inactivity from the user (no request happened containing the session id in the request cookies).

The view state is posted on subsequent post back in a hidden field.

You can do this by creating a constraint and connecting it via interface builder

See explanation: Auto_Layout_Constraints_in_Interface_Builder

raywenderlich beginning-auto-layout

AutolayoutPG Articles constraint Fundamentals

@interface ViewController : UIViewController {
    IBOutlet NSLayoutConstraint *leadingSpaceConstraint;
    IBOutlet NSLayoutConstraint *topSpaceConstraint;
}
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *leadingSpaceConstraint;

connect this Constraint outlet with your sub views Constraint or connect super views Constraint too and set it according to your requirements like this

 self.leadingSpaceConstraint.constant = 10.0;//whatever you want to assign

I hope this clarifies it.

Sometimes size "picks the wrong one" and returns a hash (which is what count would do)

In that case, use length to get an integer instead of hash.

Building on a previous answer by @user1172173 that addressed SQL Injection vulnerabilities, see below:

CREATE PROCEDURE [dbo].[spQ_SomeColumnByCustomerId](
@CustomerId int,
@SchemaName varchar(20),
@TableName nvarchar(200)) AS
SET Nocount ON
DECLARE @SQLQuery AS NVARCHAR(500)
DECLARE @ParameterDefinition AS NVARCHAR(100)
DECLARE @Table_ObjectId int;
DECLARE @Schema_ObjectId int;
DECLARE @Schema_Table_SecuredFromSqlInjection NVARCHAR(125)

SET @Table_ObjectId = OBJECT_ID(@TableName)
SET @Schema_ObjectId = SCHEMA_ID(@SchemaName)
SET @Schema_Table_SecuredFromSqlInjection = SCHEMA_NAME(@Schema_ObjectId) + '.' + OBJECT_NAME(@Table_ObjectId)

SET @SQLQuery = N'SELECT TOP 1 ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn 
FROM dbo.Customer 
INNER JOIN ' + @Schema_Table_SecuredFromSqlInjection + ' 
ON dbo.Customer.Customerid = ' + @Schema_Table_SecuredFromSqlInjection + '.CustomerId 
WHERE dbo.Customer.CustomerID = @CustomerIdParam 
ORDER BY ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn DESC' 
SET @ParameterDefinition =  N'@CustomerIdParam INT'

EXECUTE sp_executesql @SQLQuery, @ParameterDefinition, @CustomerIdParam = @CustomerId; RETURN

You can't do what I think you're asking to do.

The only privileges you can grant on procedures are EXECUTE and DEBUG.

If you want to allow user B to create a procedure in user A schema, then user B must have the CREATE ANY PROCEDURE privilege. ALTER ANY PROCEDURE and DROP ANY PROCEDURE are the other applicable privileges required to alter or drop user A procedures for user B. All are wide ranging privileges, as it doesn't restrict user B to any particular schema. User B should be highly trusted if granted these privileges.

EDIT:

As Justin mentioned, the way to give execution rights to A for a procedure owned by B:

GRANT EXECUTE ON b.procedure_name TO a;

Assuming employee numbers are in the first column and their names are in the second:

=VLOOKUP(A1, Sheet2!A:B, 2,false)

Well if you want fully transparent than you can use

border: 5px solid transparent;

If you mean opaque/transparent, than you can use

border: 5px solid rgba(255, 255, 255, .5);

Here, a means alpha, which you can scale, 0-1.

Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.

For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.

Demo

Demo 2 (With a background image for nested div)

Demo 3 (With an img tag instead of a background-image)

body {
    background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);   
}

div.wrap {
    border: 5px solid #fff; /* Fall back, not used in fiddle */
    border: 5px solid rgba(255, 255, 255, .5);
    height: 400px;
    width: 400px;
    margin: 50px;
    border-radius: 50%;
}

div.inner {
    background: #fff; /* Fall back, not used in fiddle */
    background: rgba(255, 255, 255, .5);
    height: 380px;
    width: 380px;
    border-radius: 50%; 
    margin: auto; /* Horizontal Center */
    margin-top: 10px; /* Vertical Center ... Yea I know, that's 
                         manually calculated*/
}

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.

c.f. http://docs.python.org/3/tutorial/datastructures.html#list-comprehensions

For a discussion on why to prefer comprehensions over higher-order functions such as map, go to http://www.artima.com/weblogs/viewpost.jsp?thread=98196.

I ran into this scenario recently (well over 7 million rows) and eneded up using sqlcmd via powershell (after parsing raw data into SQL insert statements) in segments of 5,000 at a time (SQL can't handle 7 million lines in one lump job or even 500,000 lines for that matter unless its broken down into smaller 5K pieces. You can then run each 5K script one after the other.) as I needed to leverage the new sequence command in SQL Server 2012 Enterprise. I couldn't find a programatic way to insert seven million rows of data quickly and efficiently with said sequence command.

Secondly, one of the things to look out for when inserting a million rows or more of data in one sitting is the CPU and memory consumption (mostly memory) during the insert process. SQL will eat up memory/CPU with a job of this magnitude without releasing said processes. Needless to say if you don't have enough processing power or memory on your server you can crash it pretty easily in a short time (which I found out the hard way). If you get to the point to where your memory consumption is over 70-75% just reboot the server and the processes will be released back to normal.

I had to run a bunch of trial and error tests to see what the limits for my server was (given the limited CPU/Memory resources to work with) before I could actually have a final execution plan. I would suggest you do the same in a test environment before rolling this out into production.

E:>move "blogger code.txt" d:/"blogger code.txt"

    1 file(s) moved.

"blogger code.txt" is a file name

The file move from E: drive to D: drive

Is declaring a variable as private static varName; any different from declaring a variable private varName;?

Yes, both are different. And the first one is called class variable because it holds single value for that class whereas the other one is called instance variable because it can hold different value for different instances(Objects). The first one is created only once in jvm and other one is created once per instance i.e if you have 10 instances then you will have 10 different private varName; in jvm.

Does declaring the variable as static give it other special properties?

Yes, static variables gets some different properties than normal instance variables. I've mentioned few already and let's see some here: class variables (instance variables which are declared as static) can be accessed directly by using class name like ClassName.varName. And any object of that class can access and modify its value unlike instance variables are accessed by only its respective objects. Class variables can be used in static methods.

What is the use of a private static variable in Java?

Logically, private static variable is no different from public static variable rather the first one gives you more control. IMO, you can literally replace public static variable by private static variable with help of public static getter and setter methods.

One widely used area of private static variable is in implementation of simple Singleton pattern where you will have only single instance of that class in whole world. Here static identifier plays crucial role to make that single instance is accessible by outside world(Of course public static getter method also plays main role).

public class Singleton {
    private static Singleton singletonInstance = new Singleton();

    private Singleton(){}

    public static Singleton getInstance(){
        return Singleton.singletonInstance;
    }
}

try below code

Directory.GetFiles(txtFolderPath.Text, "*ProfileHandler.cs",SearchOption.AllDirectories)

An advance approach is using Kotlin Extension function

fun Context.getRawInput(@RawRes resourceId: Int): InputStream {
    return resources.openRawResource(resourceId)
}

One more interesting thing is extension function use that is defined in Closeable scope

For example you can work with input stream in elegant way without handling Exceptions and memory managing

fun Context.readRaw(@RawRes resourceId: Int): String {
    return resources.openRawResource(resourceId).bufferedReader(Charsets.UTF_8).use { it.readText() }
}

Jaminto did a great job of answering the question, but I recently went through the process myself and wanted to expand on Jaminto's answer.

I'm assuming that you already have an EC2 instance created and have associated an Elastic IP Address to it.

Step #1: Install vsftpd

SSH to your EC2 server. Type:

> sudo yum install vsftpd

This should install vsftpd.

Step #2: Open up the FTP ports on your EC2 instance

Next, you'll need to open up the FTP ports on your EC2 server. Log in to the AWS EC2 Management Console and select Security Groups from the navigation tree on the left. Select the security group assigned to your EC2 instance. Then select the Inbound tab, then click Edit:

Add two Custom TCP Rules with port ranges 20-21 and 1024-1048. For Source, you can select 'Anywhere'. If you decide to set Source to your own IP address, be aware that your IP address might change if it is being assigned via DHCP.

Step #3: Make updates to the vsftpd.conf file

Edit your vsftpd conf file by typing:

> sudo vi /etc/vsftpd/vsftpd.conf

Disable anonymous FTP by changing this line:

anonymous_enable=YES

to

anonymous_enable=NO

Then add the following lines to the bottom of the vsftpd.conf file:

pasv_enable=YES
pasv_min_port=1024
pasv_max_port=1048
pasv_address=<Public IP of your instance> 

Your vsftpd.conf file should look something like the following - except make sure to replace the pasv_address with your public facing IP address:

To save changes, press escape, then type :wq, then hit enter.

Step #4: Restart vsftpd

Restart vsftpd by typing:

> sudo /etc/init.d/vsftpd restart

You should see a message that looks like:

If this doesn't work, try:

> sudo /sbin/service vsftpd restart

Step #5: Create an FTP user

If you take a peek at /etc/vsftpd/user_list, you'll see the following:

# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers
# for users that are denied.
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody

This is basically saying, "Don't allow these users FTP access." vsftpd will allow FTP access to any user not on this list.

So, in order to create a new FTP account, you may need to create a new user on your server. (Or, if you already have a user account that's not listed in /etc/vsftpd/user_list, you can skip to the next step.)

Creating a new user on an EC2 instance is pretty simple. For example, to create the user 'bret', type:

> sudo adduser bret
> sudo passwd bret

Here's what it will look like:

Step #6: Restricting users to their home directories

At this point, your FTP users are not restricted to their home directories. That's not very secure, but we can fix it pretty easily.

Edit your vsftpd conf file again by typing:

> sudo vi /etc/vsftpd/vsftpd.conf

Un-comment out the line:

chroot_local_user=YES

It should look like this once you're done:

Restart the vsftpd server again like so:

> sudo /etc/init.d/vsftpd restart

All done!

Appendix A: Surviving a reboot

vsftpd doesn't automatically start when your server boots. If you're like me, that means that after rebooting your EC2 instance, you'll feel a moment of terror when FTP seems to be broken - but in reality, it's just not running!. Here's a handy way to fix that:

> sudo chkconfig --level 345 vsftpd on

Alternatively, if you are using redhat, another way to manage your services is by using this nifty graphic user interface to control which services should automatically start:

>  sudo ntsysv

Now vsftpd will automatically start up when your server boots up.

Appendix B: Changing a user's FTP home directory

* NOTE: Iman Sedighi has posted a more elegant solution for restricting users access to a specific directory. Please refer to his excellent solution posted as an answer *

You might want to create a user and restrict their FTP access to a specific folder, such as /var/www. In order to do this, you'll need to change the user's default home directory:

> sudo usermod -d /var/www/ username

In this specific example, it's typical to give the user permissions to the 'www' group, which is often associated with the /var/www folder:

> sudo usermod -a -G www username

On OS X you can use:

ls -lead

The e option shows ACLs. And ACLs are very important to knowing what the exact permissions on your system are.

If you want to get the first element whose id is 1 while object is being searched, you can use this function:

function customFilter(object){
    if(object.hasOwnProperty('id') && object["id"] == 1)
        return object;

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            var o = customFilter(object[Object.keys(object)[i]]);
            if(o != null)
                return o;
        }
    }

    return null;
}

If you want to get all elements whose id is 1, then (all elements whose id is 1 are stored in result as you see):

function customFilter(object, result){
    if(object.hasOwnProperty('id') && object.id == 1)
        result.push(object);

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            customFilter(object[Object.keys(object)[i]], result);
        }
    }
}

In my case, i installed node with NVM and after installing z Shell, node and nvm command didn't worked. So what worked for me was installing nvm again with this command :

wget https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
sudo zsh install.sh

Above commands installed nvm again, since node was already installed, it added the node path automatically in .zshrc file and everything worked.

This is called type assertion in TypeScript, and since TypeScript 1.6, there are two ways to express this:

// Original syntax
var markerSymbolInfo = <MarkerSymbolInfo> symbolInfo;

// Newer additional syntax
var markerSymbolInfo = symbolInfo as MarkerSymbolInfo;

Both alternatives are functionally identical. The reason for introducing the as-syntax is that the original syntax conflicted with JSX, see the design discussion here.

If you are in a position to choose, just use the syntax that you feel more comfortable with. I personally prefer the as-syntax as it feels more fluent to read and write.

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

Example.. "OTHER"

You can do this by comparing each field using the NULL-safe equals operator <=> and then negating the result using NOT.

The complete trigger would become:

DROP TRIGGER IF EXISTS `my_trigger_name`;

DELIMITER $$

CREATE TRIGGER `my_trigger_name` AFTER UPDATE ON `my_table_name` FOR EACH ROW 
    BEGIN
        /*Add any fields you want to compare here*/
        IF !(OLD.a <=> NEW.a AND OLD.b <=> NEW.b) THEN
            INSERT INTO `my_other_table` (
                `a`,
                 `b`
            ) VALUES (
                NEW.`a`,
                NEW.`b`
            );
        END IF;
    END;$$

DELIMITER ;

(Based on a different answer of mine.)

https://turbo.net/ offers a browser sandbox in which containerised virtual machines run browser sessions for you. I tried it with Safari on my Windows development machine and it seems to work very well.

This is a bit of an open ended question since screen sizes are changing all the time and what might have been correct two years ago would likely be out of date now.

I use Twitter Bootstrap 3 at present and it uses a fluid grid system designed to work at sizes ranging from mobile/very small all the way up to the huge wide screen monitors that are now available.

Currently the upper default in BS3 is 1200px which translates to a container width of 1144px after taking account of margins and padding of the grids elements.

In my experience, modern designers are working to a width of around 1366px for desktop. All recent designs I've been given to implement have been 1366px.

Note also that you can customise the BS3 grid quite heavily. For example we will use a 32 column grid with 4px gutter in our sites/designs going forwards.

Ultimately the decision on page width needs to be made based on your website analytics and the screen sizes that your visitors typically use.

Its Shift + Alt + 2 to split into 2 screens. More options are found under the menu item View -> Layout.
Once the screen is split, you can open files using the shortcuts:
1. Ctrl + P (From existing directories within sublime) or
2. Ctrl + O(Browse directory)

The right way for Select2 3.x is:

$('select').select2("enable", false)

This works fine.

Step 1: Make a new project

Step 2: in ViewController.swift

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // CODE
        let btn = UIButton(type: UIButtonType.System) as UIButton        
        btn.backgroundColor = UIColor.blueColor()
        btn.setTitle("CALL TPT AGENT", forState: UIControlState.Normal)
        btn.frame = CGRectMake(100, 100, 200, 100)
        btn.addTarget(self, action: "clickMe:", forControlEvents: UIControlEvents.TouchUpInside)
        self.view.addSubview(btn)

    }

    func clickMe(sender:UIButton!) {
      print("CALL")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

grep -v is your friend:

grep --help | grep invert  

-v, --invert-match select non-matching lines

Also check out the related -L (the complement of -l).

-L, --files-without-match only print FILE names containing no match

List<T> for strongly typed one, or ArrayList if you have .NET 1.1 or love to cast variables.

Let me make it simple and clear. Lets use the re module in python to escape the special characters.

Python script :

import re
s = "C:\Users\Josh\Desktop"
print s
print re.escape(s)

Output :

C:\Users\Josh\Desktop
C:\\Users\\Josh\\Desktop

Explanation :

Now observe that re.escape function on escaping the special chars in the given string we able to add an other backslash before each backslash, and finally the output results in a double backslash, the desired output.

Hope this helps you.

As a suggestion, you also can use the QChar::digitValue() to obtain the numeric value of the digit. For example:

for (int var = 0; var < myString.length(); ++var) {
    bool ok;
    if (myString.at(var).isDigit()){
        int digit = myString.at(var).digitValue();
        //DO SOMETHING HERE WITH THE DIGIT
    }
}

Source: Converting one element from a QString to int

Here's what I'm currently using to accomplish that.

$.xhrPool = [];
$.xhrPool.abortAll = function() {
  _.each(this, function(jqXHR) {
    jqXHR.abort();
  });
};
$.ajaxSetup({
  beforeSend: function(jqXHR) {
    $.xhrPool.push(jqXHR);
  }
});

Note: _.each of underscore.js is present, but obviously not necessary. I'm just lazy and I don't want to change it to $.each(). 8P

You application of js and php in totally invalid.

You have to understand a fact that JS runs on clientside, once the page loads it does not care, whether the page was a php page or jsp or asp. It executes of DOM and is related to it only.

However you can do something like this

var newLocation = "<?php echo $newlocation; ?>";
window.location = newLocation;

You see, by the time the script is loaded, the above code renders into different form, something like this

var newLocation = "your/redirecting/page.php";
window.location = newLocation;

Like above, there are many possibilities of php and js fusions and one you are doing is not one of them.

Try this. Note there's no database specified - it just runs "on the server"

psql -U postgres -c "drop database databasename"

If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:

SELECT * FROM pg_prepared_xacts;

then for every id you see, run this:

ROLLBACK PREPARED '<id>';

So I think the answer is simpler than many misleading answers above.

To start an existing container which is stopped

docker start <container-name/ID>

To stop a running container

docker stop <container-name/ID>

Then to login to the interactive shell of a container

docker exec -it <container-name/ID> bash

To start an existing container and attach to it in one command

docker start -ai <container-name/ID>

Beware, this will stop the container on exit. But in general, you need to start the container, attach and stop it after you are done.

Actually, there are five words commonly used when we talk about layers of reference models (or protocol stacks): data, segment, packet, frame and bit. And the term PDU (Protocol Data Unit) is used to refer to the packets in different layers of the OSI model. Thus PDU gives an abstract idea of the data packets. The PDU has a different meaning in different layers still we can use it as a common term.

When we come to your question, we can call all of them by using the general term PDU, but if you want to call them specifically at a given layer:

• Data: PDU of Application, Presentation and Session Layers
• Segment: PDU of Transport Layer
• Packet: PDU of network Layer
• Frame: PDU of data-link Layer
• Bit: PDU of physical Layer

Here is a diagram, since a picture is worth a thousand words:

The accepted solution wouldn't work for me as I need a child element with display: inline-block to be both horizontally and vertically centered within a 100% width parent.

I used Flexbox's justify-content and align-items properties, which respectively allow you to center elements horizontally and vertically. By setting both to center on the parent, the child element (or even multiple elements!) will be perfectly in the middle.

This solution does not require fixed width, which would have been unsuitable for me as my button's text will change.

Here is a CodePen demo and a snippet of the relevant code below:

.parent {
  display: flex;
  justify-content: center;
  align-items: center;
}

<div class="parent">
  <a class="child" href="#0">Button</a>
</div>

The answer by @akrun certainly does the trick. For future googlers who want to understand why, here is an explanation...

The new variable needs to be created first.

The variable "valueBin" needs to be already in the df in order for the conditional assignment to work. Essentially, the syntax of the code is correct. Just add one line in front of the code chuck to create this name --

df$newVariableName <- NA

Then you continue with whatever conditional assignment rules you have, like

df$newVariableName[which(df$oldVariableName<=250)] <- "<=250"

I blame whoever wrote that package's error message... The debugging was made especially confusing by that error message. It is irrelevant information that you have two arrays in the df with different lengths. No. Simply create the new column first. For more details, consult this post https://www.r-bloggers.com/translating-weird-r-errors/

In my opinion the bare minimum implementation has two requirements. A state that keeps track of whether the modal is open or not, and a portal to render the modal outside of the standard react tree.

The ModalContainer component below implements those requirements along with corresponding render functions for the modal and the trigger, which is responsible for executing the callback to open the modal.

import React from 'react';
import PropTypes from 'prop-types';
import Portal from 'react-portal';

class ModalContainer extends React.Component {
  state = {
    isOpen: false,
  };

  openModal = () => {
    this.setState(() => ({ isOpen: true }));
  }

  closeModal = () => {
    this.setState(() => ({ isOpen: false }));
  }

  renderModal() {
    return (
      this.props.renderModal({
        isOpen: this.state.isOpen,
        closeModal: this.closeModal,
      })
    );
  }

  renderTrigger() {
     return (
       this.props.renderTrigger({
         openModal: this.openModal
       })
     )
  }

  render() {
    return (
      <React.Fragment>
        <Portal>
          {this.renderModal()}
        </Portal>
        {this.renderTrigger()}
      </React.Fragment>
    );
  }
}

ModalContainer.propTypes = {
  renderModal: PropTypes.func.isRequired,
  renderTrigger: PropTypes.func.isRequired,
};

export default ModalContainer;

And here's a simple use case...

import React from 'react';
import Modal from 'react-modal';
import Fade from 'components/Animations/Fade';
import ModalContainer from 'components/ModalContainer';

I use render functions, because I want to isolate state management and boilerplate logic from the implementation of the rendered modal and trigger component. This allows the rendered components to be whatever you want them to be. In your case, I suppose the modal component could be a connected component that receives a callback function that dispatches an asynchronous action.

If you need to send dynamic props to the modal component from the trigger component, which hopefully doesn't happen too often, I recommend wrapping the ModalContainer with a container component that manages the dynamic props in its own state and enhance the original render methods like so.

import React from 'react'
import partialRight from 'lodash/partialRight';
import ModalContainer from 'components/ModalContainer';

class ErrorModalContainer extends React.Component {
  state = { message: '' }

  onError = (message, callback) => {
    this.setState(
      () => ({ message }),
      () => callback && callback()
    );
  }

  renderModal = (props) => (
    this.props.renderModal({
       ...props,
       message: this.state.message,
    })
  )

  renderTrigger = (props) => (
    this.props.renderTrigger({
      openModal: partialRight(this.onError, props.openModal)
    })
  )

  render() {
    return (
      <ModalContainer
        renderModal={this.renderModal}
        renderTrigger={this.renderTrigger}
      />
    )
  }
}

ErrorModalContainer.propTypes = (
  ModalContainer.propTypes
);

export default ErrorModalContainer;

I know it is an old question, but for the record here is a kind of a solution to the problem of multiline lambda problem in which the result of one call is consumed by another call.

I hope it is not super hacky, since it is based only on standard library functions and uses no dunder methods.

Below is a simple example in which we start with x = 3 and then in the first line we add 1 and then in the second line we add 2 and get 6 as the output.

from functools import reduce

reduce(lambda data, func: func(data), [
    lambda x: x + 1,
    lambda x: x + 2
], 3)

## Output: 6

Why use GROUP BY at all?

For anyone who wants to work in pixels rather than inches this will work.

Plus the usual you will also need

from matplotlib.transforms import Bbox

Then you can use the following:

my_dpi = 100 # Good default - doesn't really matter

# Size of output in pixels
h = 224
w = 224

fig, ax = plt.subplots(1, figsize=(w/my_dpi, h/my_dpi), dpi=my_dpi)

ax.set_position([0, 0, 1, 1]) # Critical!

# Do some stuff
ax.imshow(img)
ax.imshow(heatmap) # 4-channel RGBA
ax.plot([50, 100, 150], [50, 100, 150], color="red")

ax.axis("off")

fig.savefig("saved_img.png",
            bbox_inches=Bbox([[0, 0], [w/my_dpi, h/my_dpi]]),
            dpi=my_dpi)

using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php

so set $dbserver to your server name, e.g. $dbserver='mysql.example.com';

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##

## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##

$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';

Yeah, you can install opencv (this is a library used for image processing, and computer vision), and use the cv2.resize function. And for instance use:

import cv2
import numpy as np

img = cv2.imread('your_image.jpg')
res = cv2.resize(img, dsize=(54, 140), interpolation=cv2.INTER_CUBIC)

Here img is thus a numpy array containing the original image, whereas res is a numpy array containing the resized image. An important aspect is the interpolation parameter: there are several ways how to resize an image. Especially since you scale down the image, and the size of the original image is not a multiple of the size of the resized image. Possible interpolation schemas are:

• INTER_NEAREST - a nearest-neighbor interpolation
• INTER_LINEAR - a bilinear interpolation (used by default)
• INTER_AREA - resampling using pixel area relation. It may be a preferred method for image decimation, as it gives moire’-free results. But when the image is zoomed, it is similar to the INTER_NEAREST method.
• INTER_CUBIC - a bicubic interpolation over 4x4 pixel neighborhood
• INTER_LANCZOS4 - a Lanczos interpolation over 8x8 pixel neighborhood

Like with most options, there is no "best" option in the sense that for every resize schema, there are scenarios where one strategy can be preferred over another.

You can change the port in the console by running the following on Windows:

SET PORT=8000

For Mac, Linux or Windows WSL use the following:

export PORT=8000

The export sets the environment variable for the current shell and all child processes like npm that might use it.

If you want the environment variable to be set just for the npm process, precede the command with the environment variable like this (on Mac and Linux and Windows WSL):

PORT=8000 npm run start

As the error message is trying very hard to tell you, you can't deserialize a single object into a collection (List<>).

You want to deserialize into a single RootObject.

You can use an extension method:

public static class StringExtension
{
    public static string GetLast(this string source, int tail_length)
    {
       if(tail_length >= source.Length)
          return source;
       return source.Substring(source.Length - tail_length);
    }
}

And then call:

string mystring = "34234234d124";
string res = mystring.GetLast(4);

i think you can download the latest android SDK and use it.i do this and fixed the problem and work well. here is the link: http://developer.android.com/sdk/index.html#download

If the view is accessed via a stored procedure, the execute grant is insufficient to access the view. You must grant select explicitly.

Only IE and WebKit support zoom, and yes, in theory it does exactly what you're saying.

Try it out on an image to see it's full effect :)

Try

$ yum provides ld-linux.so.2
$ yum update
$ yum install glibc.i686 libfreetype.so.6 libfontconfig.so.1 libstdc++.so.6

Hope this clears out.

I solved it with converting it back to number using JavaScript's Number() function

var x = 2.2873424;
x = Number(x.toFixed(2));

No need for a StringBuilder:

string path = @"c:\hereIAm.txt";
if (!File.Exists(path)) 
{
    // Create a file to write to.
    using (StreamWriter sw = File.CreateText(path)) 
    {
        sw.WriteLine("Here");
        sw.WriteLine("I");
        sw.WriteLine("am.");
    }    
} 

But of course you can use the StringBuilder to create all lines and write them to the file at once.

sw.Write(stringBuilder.ToString());

Only MyISAM allows for FULLTEXT, as seen here.

Try this:

CREATE TABLE gamemech_chat (
  id bigint(20) unsigned NOT NULL auto_increment,
  from_userid varchar(50) NOT NULL default '0',
  to_userid varchar(50) NOT NULL default '0',
  text text NOT NULL,
  systemtext text NOT NULL,
  timestamp datetime NOT NULL default '0000-00-00 00:00:00',
  chatroom bigint(20) NOT NULL default '0',
  PRIMARY KEY  (id),
  KEY from_userid (from_userid),
  FULLTEXT KEY from_userid_2 (from_userid),
  KEY chatroom (chatroom),
  KEY timestamp (timestamp)
) ENGINE=MyISAM;

Use >> instead of > when directing output to a file:

your_command >> file_to_append_to

If file_to_append_to does not exist, it will be created.

Example:

$ echo "hello" > file
$ echo "world" >> file
$ cat file 
hello
world

Here's the shortest solution, based on vh. Please note that vh is not supported in some older browsers.

CSS:

div {
    width: 100%;
    height: 100vh;
}

HTML:

<div>This div is fullscreen :)</div>

Another possibility, if using the -o (output file) option - the destination directory does not exist.

eg. if you have -o /tmp/download/abc.txt and /tmp/download does not exist.

Hence, ensure any required directories are created/exist beforehand, use the --create-dirs option as well as -o if necessary

I got this issue after running the google-cloud-sdk install script, which adds command-completion to the shell via an entry in .zshrc.

Following Homebrew's instructions for configuring completions in zsh was helpful.

Additionally, if you receive “zsh compinit: insecure directories” warnings when attempting to load these completions, you may need to run this: chmod -R go-w "$(brew --prefix)/share"

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

That's my take:

<ControlTemplate>
    <Grid>
        <Grid.Resources>

            <Style TargetType="TextBox">
                <Setter Property="Padding" Value="4"/>
                <Setter Property="BorderThickness" Value="2"/>
            </Style>
        </Grid.Resources>

        <TextBox x:Name="TbSearch"/>
        <TextBox x:Name="TbHint" Text="Suche" Foreground="LightGray"
                 Visibility="Hidden" IsHitTestVisible="False" Focusable="False"/>
    </Grid>

    <ControlTemplate.Triggers>
        <MultiTrigger>
            <MultiTrigger.Conditions>
                <Condition SourceName="TbSearch" Property="Text" Value="{x:Static sys:String.Empty}"/>
                <Condition SourceName="TbSearch" Property="IsKeyboardFocused" Value="False"/>
            </MultiTrigger.Conditions>
            <MultiTrigger.Setters>
                <Setter TargetName="TbHint" Property="Visibility" Value="Visible"/>
            </MultiTrigger.Setters>
        </MultiTrigger>

        <MultiTrigger>

                <Condition SourceName="TbSearch" Property="IsKeyboardFocused" Value="False"/>
            </MultiTrigger.Conditions>
            <MultiTrigger.Setters>

Most other answers including the top one have flaws in my opinion.

This solution works under all circumstances. Pure XAML, easily reusable.

The Problem is related to MySql Driver

Class.forName("com.mysql.jdbc.Driver");

Add the MySQL jdbc driver jar file in to your classpath.

Also i have this error on JDK. I build the ClassPath Properly then I put the "mysql-connector-java-5.1.25-bin" in dir "C:\Program Files\Java\jre7\lib\ext" in this dir i have my JDK. then compile and Run again then it's working fine.

You need to install the APK on the emulator. You can do this with the adb command line tool that is included in the Android SDK.

adb -e install -r yourapp.apk

Once you've done that you should be able to run the app.

The -e and -r flags might not be necessary. They just specify that you are using an emulator (if you also have a device connected) and that you want to replace the app if it already exists.

My 2 cents, from a current implementation Point of View and for SWIG users on k8 (x86_64) architecture.

Linux

First long long and long int are different types but sizeof(long long) == sizeof(long int) == sizeof(int64_t)

Gcc

First try to find where and how the compiler define int64_t and uint64_t

grepc -rn "typedef.*INT64_TYPE" /lib/gcc
/lib/gcc/x86_64-linux-gnu/9/include/stdint-gcc.h:43:typedef __INT64_TYPE__ int64_t;
/lib/gcc/x86_64-linux-gnu/9/include/stdint-gcc.h:55:typedef __UINT64_TYPE__ uint64_t;

So we need to find this compiler macro definition

gcc -dM -E -x c /dev/null | grep __INT64                 
#define __INT64_C(c) c ## L
#define __INT64_MAX__ 0x7fffffffffffffffL
#define __INT64_TYPE__ long int

gcc -dM -E -x c++ /dev/null | grep __INT64
#define __INT64_C(c) c ## L
#define __INT64_MAX__ 0x7fffffffffffffffL
#define __INT64_TYPE__ long int

Clang

clang -dM -E -x c++ /dev/null | grep INT64_TYPE
#define __INT64_TYPE__ long int
#define __UINT64_TYPE__ long unsigned int

Clang, GNU compilers:
-dM dumps a list of macros.
-E prints results to stdout instead of a file.
-x c and -x c++ select the programming language when using a file without a filename extension, such as /dev/null

Ref: https://web.archive.org/web/20190803041507/http://nadeausoftware.com/articles/2011/12/c_c_tip_how_list_compiler_predefined_macros

note: for swig user, on Linux x86_64 use -DSWIGWORDSIZE64

MacOS

On Catalina 10.15 IIRC

Clang

clang -dM -E -x c++ /dev/null | grep INT64_TYPE
#define __INT64_TYPE__ long long int
#define __UINT64_TYPE__ long long unsigned int

Clang:
-dM dumps a list of macros.
-E prints results to stdout instead of a file.
-x c and -x c++ select the programming language when using a file without a filename extension, such as /dev/null

Ref: https://web.archive.org/web/20190803041507/http://nadeausoftware.com/articles/2011/12/c_c_tip_how_list_compiler_predefined_macros

note: for swig user, on macOS x86_64 don't use -DSWIGWORDSIZE64

Visual Studio 2019

First sizeof(long int) == 4 and sizeof(long long) == 8

in stdint.h we have:

#if _VCRT_COMPILER_PREPROCESSOR

typedef signed char        int8_t;
typedef short              int16_t;
typedef int                int32_t;
typedef long long          int64_t;
typedef unsigned char      uint8_t;
typedef unsigned short     uint16_t;
typedef unsigned int       uint32_t;
typedef unsigned long long uint64_t;

note: for swig user, on windows x86_64 don't use -DSWIGWORDSIZE64

SWIG Stuff

First see https://github.com/swig/swig/blob/3a329566f8ae6210a610012ecd60f6455229fe77/Lib/stdint.i#L20-L24 so you can control the typedef using SWIGWORDSIZE64 but...

now the bad: SWIG Java and SWIG CSHARP do not take it into account

So you may want to use

#if defined(SWIGJAVA)
#if defined(SWIGWORDSIZE64)
%define PRIMITIVE_TYPEMAP(NEW_TYPE, TYPE)
%clear NEW_TYPE;
%clear NEW_TYPE *;
%clear NEW_TYPE &;
%clear const NEW_TYPE &;
%apply TYPE { NEW_TYPE };
%apply TYPE * { NEW_TYPE * };
%apply TYPE & { NEW_TYPE & };
%apply const TYPE & { const NEW_TYPE & };
%enddef // PRIMITIVE_TYPEMAP
PRIMITIVE_TYPEMAP(long int, long long);
PRIMITIVE_TYPEMAP(unsigned long int, long long);
#undef PRIMITIVE_TYPEMAP
#endif // defined(SWIGWORDSIZE64)
#endif // defined(SWIGJAVA)

and

#if defined(SWIGCSHARP)
#if defined(SWIGWORDSIZE64)
%define PRIMITIVE_TYPEMAP(NEW_TYPE, TYPE)
%clear NEW_TYPE;
%clear NEW_TYPE *;
%clear NEW_TYPE &;
%clear const NEW_TYPE &;
%apply TYPE { NEW_TYPE };
%apply TYPE * { NEW_TYPE * };
%apply TYPE & { NEW_TYPE & };
%apply const TYPE & { const NEW_TYPE & };
%enddef // PRIMITIVE_TYPEMAP
PRIMITIVE_TYPEMAP(long int, long long);
PRIMITIVE_TYPEMAP(unsigned long int, unsigned long long);
#undef PRIMITIVE_TYPEMAP
#endif // defined(SWIGWORDSIZE64)
#endif // defined(SWIGCSHARP)

So int64_t aka long int will be bind to Java/C# long on Linux...

One of the putty tools is pscp.exe; it will allow you to copy files from your remote host.

If you need to do substitutions across line boundaries, then using ruby -pi -e won't work because the p processes one line at a time. Instead, I recommend the following, although it could fail with a multi-GB file:

ruby -e "file='translation.ja.yml'; IO.write(file, (IO.read(file).gsub(/\s+'$/, %q('))))"

The is looking for white space (potentially including new lines) following by a quote, in which case it gets rid of the whitespace. The %q(')is just a fancy way of quoting the quote character.

There is indeed a Groovier Way.

if(members){
    //Some work
}

does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. :)

I had the same problem. Here is how I solved it. The solution loads the lib directory and all the subdirectories (not only the direct). Of course you can use this for all directories.

# application.rb
config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]

You can use a background image

.application-title img {_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
  box-sizing:border-box;_x000D_
  padding-left: 200px;_x000D_
  /*width of the image*/_x000D_
  background: url(http://lorempixel.com/200/200/city/2) left top no-repeat;_x000D_
}

<div class="application-title">_x000D_
  <img src="http://lorempixel.com/200/200/city/1/">_x000D_
</div><br />_x000D_
Original Image: <br />_x000D_
_x000D_
<img src="http://lorempixel.com/200/200/city/1/">

Simply use

SELECT DATEPART(YEAR, SomeDateColumn)

It will return the portion of a DATETIME type that corresponds to the option you specify. SO DATEPART(YEAR, GETDATE()) would return the current year.

Can pass other time formatters instead of YEAR like

• DAY
• MONTH
• SECOND
• MILLISECOND
• ...etc.

Yes that is valid syntax but it may well not do what you want.

Execution will continue after your RAISERROR except if you add a RETURN. So you will need to add a block with BEGIN ... END to hold the two statements.

Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.

Finally I'd simplify the conditions using IN

CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
                                            @UserType TINYINT,
                                            @UserName NVARCHAR(100),
                                            @Password NVARCHAR(100))
AS
  BEGIN
      IF ( @TenantId IS NULL
           AND @UserType IN ( 0, 1 ) )
        BEGIN
            RAISERROR('The value for @TenantID should not be null',15,1);

            RETURN;
        END
  END 

JE and JZ are just different names for exactly the same thing: a conditional jump when ZF (the "zero" flag) is equal to 1.

(Similarly, JNE and JNZ are just different names for a conditional jump when ZF is equal to 0.)

You could use them interchangeably, but you should use them depending on what you are doing:

• JZ/JNZ are more appropriate when you are explicitly testing for something being equal to zero:

  dec  ecx
  jz   counter_is_now_zero
  

• JE and JNE are more appropriate after a CMP instruction:

  cmp  edx, 42
  je   the_answer_is_42
  

  (A CMP instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1 when the operands are equal and ZF=0 when they're not.)

FLAG_ACTIVITY_NEW_TASK is the problem here which initiates a new task .Just remove it & you are done.

Well I recommend you to read what every Flag does before working with them

Inside my UIViewController derived class, I am using the following inside viewDidLoad:

UIBarButtonItem *flipButton = [[UIBarButtonItem alloc] 
                               initWithTitle:@"Flip"                                            
                               style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(flipView:)];
self.navigationItem.rightBarButtonItem = flipButton;
[flipButton release];

This adds a button to the right hand side with the title Flip, which calls the method:

-(IBAction)flipView

This looks very much like you #3, but it is working within my code.

        BufferedReader(InputStreamReader(inputStream)).use {
            val response = StringBuffer()

            var inputLine = it.readLine()
            while (inputLine != null) {
                response.append(inputLine)
                inputLine = it.readLine()
            }
            println("Response : $response")
        }
    }
}

GET with Parameters:

fun sendGetRequest(userName:String, password:String) {

        var reqParam = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode(userName, "UTF-8")
        reqParam += "&" + URLEncoder.encode("password", "UTF-8") + "=" + URLEncoder.encode(password, "UTF-8")

Redis is better.

The Pros of Redis are ,

1. It has a lot of data storage options such as string , sets , sorted sets , hashes , bitmaps
2. Disk Persistence of records
3. Stored Procedure (LUA scripting) support
4. Can act as a Message Broker using PUB/SUB

Whereas Memcache is an in-memory key value cache type system.

1. No support for various data type storages like lists , sets as in redis.
2. The major con is Memcache has no disk persistence .

If it's in a class, you can use getattr:

class MyClass(object):
    def install(self):
          print "In install"

method_name = 'install' # set by the command line options
my_cls = MyClass()

method = None
try:
    method = getattr(my_cls, method_name)
except AttributeError:
    raise NotImplementedError("Class `{}` does not implement `{}`".format(my_cls.__class__.__name__, method_name))

method()

or if it's a function:

def install():
       print "In install"

method_name = 'install' # set by the command line options
possibles = globals().copy()
possibles.update(locals())
method = possibles.get(method_name)
if not method:
     raise NotImplementedError("Method %s not implemented" % method_name)
method()

If we need to share multiple variables use the below format

//module.js
   let name='foobar';
   let city='xyz';
   let company='companyName';

   module.exports={
    name,
    city,
    company
  }

Usage

  // main.js
    require('./modules');
    console.log(name); // print 'foobar'

-> Add a permission to read contacts data to your application manifest.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

-> Use Intent.Action_Pick in your Activity like below

Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
        startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);

-> Then Override the onActivityResult()

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // check whether the result is ok
        if (resultCode == RESULT_OK) {
            // Check for the request code, we might be usign multiple startActivityForReslut
            switch (requestCode) {
            case RESULT_PICK_CONTACT:
               Cursor cursor = null;
        try {
            String phoneNo = null ;
            String name = null;           
            Uri uri = data.getData();            
            cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();           
            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex); 

            textView2.setText(phoneNo);
        } catch (Exception e) {
            e.printStackTrace();
        }
                break;
            }
        } else {
            Log.e("MainActivity", "Failed to pick contact");
        }
    }

This will work check it out

The first problem is that your query string is wrong:

I think this: "INSERT INTO employee(hans,germany) values(?,?)" should be like this: "INSERT INTO employee(name,country) values(?,?)"

The other problem is that you have a parameterized PreparedStatement and you don't set the parameters before running it.

You should add these to your code:

String inserting = "INSERT INTO employee(name,country) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1,"hans"); // <----- this
ps.setString(2,"germany");// <---- and this
ps.executeUpdate();

Thats how i do it, not much code, easy to understand, fits my needs:

void bench(std::function<void()> fnBench, std::string name, size_t iterations)
{
    if (iterations == 0)
        return;
    if (fnBench == nullptr)
        return;
    std::chrono::high_resolution_clock::time_point start, end;
    if (iterations == 1)
    {
        start = std::chrono::high_resolution_clock::now();
        fnBench();
        end = std::chrono::high_resolution_clock::now();
    }
    else
    {
        start = std::chrono::high_resolution_clock::now();
        for (size_t i = 0; i < iterations; ++i)
            fnBench();
        end = std::chrono::high_resolution_clock::now();
    }
    printf
    (
        "bench(*, \"%s\", %u) = %4.6lfs\r\n",
        name.c_str(),
        iterations,
        std::chrono::duration_cast<std::chrono::duration<double>>(end - start).count()
    );
}

Usage:

bench
(
    []() -> void // function
    {
        // Put your code here
    },
    "the name of this", // name
    1000000 // iterations
);

Did you try setting the style:

input {
    text-align:right;
}

Just tested, this works fine (in FF3 at least):

<html>
    <head>
        <title>Blah</title>
        <style type="text/css">
        input { text-align:right; }
        </style>
    </head>
    <body>
        <input type="text" value="2">
    </body>
</html>

You'll probably want to throw a class on these inputs, and use that class as the selector. I would shy away from "rightAligned" or something like that. In a class name, you want to describe what the element's function is, not how it should be rendered. "numeric" might be good, or perhaps the business function of the text boxes.

If you are trying to set the background as some other resource file in your drawable folder, say, a custom-button.xml, then try this:

button_name.setBackgroundResource(R.drawable.custom_button_file_name);

eg. Say, you have a custom-button.xml file. Then,

button_name.setBackgroundResource(R.drawable.custom_button);

Will set the button background as the custom-button.xml file.

The accepted solution only works on arrays, but not objects or associative arrays. Unfortunately, since Angular depends on the JavaScript implementation of array enumeration, the order of object properties cannot be consistently controlled. Some browsers may iterate through object properties lexicographically, but this cannot be guaranteed.

e.g. Given the following assignment:

$scope.cards = {
  "card2": {
    values: {
      opt1: 9,
      opt2: 12
    }
  },
  "card1": {
    values: {
      opt1: 9,
      opt2: 11
    }
  }
};

and the directive <ul ng-repeat="(key, card) in cards | orderBy:myValueFunction">, ng-repeat may iterate over "card1" prior to "card2", regardless of sort order.

To workaround this, we can create a custom filter to convert the object to an array, and then apply a custom sort function before returning the collection.

myApp.filter('orderByValue', function () {
  // custom value function for sorting
  function myValueFunction(card) {
    return card.values.opt1 + card.values.opt2;
  }

  return function (obj) {
    var array = [];
    Object.keys(obj).forEach(function (key) {
      // inject key into each object so we can refer to it from the template
      obj[key].name = key;
      array.push(obj[key]);
    });
    // apply a custom sorting function
    array.sort(function (a, b) {
      return myValueFunction(b) - myValueFunction(a);
    });
    return array;
  };
});

We cannot iterate over (key, value) pairings in conjunction with custom filters (since the keys for arrays are numerical indexes), so the template should be updated to reference the injected key names.

<ul ng-repeat="card in cards | orderByValue">
    <li>{{card.name}} {{value(card)}}</li>
</ul>

Here is a working fiddle utilizing a custom filter on an associative array: http://jsfiddle.net/av1mLpqx/1/

Alternatively you can use cmder which lets you add aliases just like linux:

alias subl="C:\Program Files\Sublime Text 3\subl.exe" $*

Also just though I'd post the answer to another related question I had,

a = x ? : y;

Is equivalent to:

a = x ? x : y;

If x is false or null then the value of y is taken.

change_column_default :employees, :foreign, false

const getJsonIndented = (obj) => JSON.stringify(newObj, null, 4).replace(/["{[,\}\]]/g, "")

const JSONDisplayer = ({children}) => (
    <div>
        <pre>{getJsonIndented(children)}</pre>
    </div>
)

Then you can easily use it:

const Demo = (props) => {
   ....
   return <JSONDisplayer>{someObj}<JSONDisplayer>
}

You could use LoadWithPartialName. However, that is deprecated as they said.

You can indeed go along with Add-Type, and in addition to the other answers, if you don't want to specify the full path of the .dll file, you could just simply do:

Add-Type -AssemblyName "Microsoft.SqlServer.Management.SMO"

To me this returned an error, because I do not have SQL Server installed (I guess), however, with this same idea I was able to load the Windows Forms assembly:

Add-Type -AssemblyName "System.Windows.Forms"

You can find out the precise assembly name belonging to the particular class on the MSDN site:

Launch the program "Run" (Windows Vista/7/8: type it in the start menu search bar) and type: C:\windows\assembly\GAC_MSIL

Then move to the parent folder (Windows Vista/7/8: by clicking on it in the explorer bar) to see all the GAC files in a normal explorer window. You can now copy, add and remove files as everywhere else.

I know the answer is in reply to a question asked 6 years ago ...

But I was looking for something similar for a few hours and then found out that: cut -c does exactly that, with an added bonus that you could also specify an offset.

cut -c 1-5 will return Hello and cut -c 7-11 will return world. No need for any other command

LayoutInflater inflater = (LayoutInflater) SettingActivity.this.getSystemService(SettingActivity.LAYOUT_INFLATER_SERVICE); 
PopupWindow pw = new PopupWindow(inflater.inflate(R.layout.gd_quick_action_slide_fontsize, null),LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT, true);
pw.showAtLocation(SettingActivity.this.findViewById(R.id.setting_fontsize), Gravity.CENTER, 0, 0);
View v= pw.getContentView();
TextView tv=v.findViewById(R.id.....);

Yo could also set labels = FALSE inside axis(...) and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it

lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)

Detailed explanation here

I add the same situation and went in a couple of stackoverfow, github and tutorials showing complex solutions. Nothing simple though! Some with "Hold the alt key and move the mouse while the cursor shows a cross" which is not for laptop users (at least for me), some others with configuration files...

I found it after a good sleep night. My environment is laptop, ubuntu and Jupyter/Ipython 5.1.0 :

Just select/highlight one line, a block or something, and then "Ctrl"+"/" and it's magic :)

Bad idea when you know the field will be in a set range- 5 to 10 character for example. I think I'd only use max if I wasn't sure what the length would be. For example a telephone number would never be more than a certain number of characters.

Can you honestly say you are that uncertain about the approximate length requirements for every field in your table?

I do get your point though- there are some fields I'd certainly consider using varchar(max).

Interestingly the MSDN docs sum it up pretty well:

Use varchar when the sizes of the column data entries vary considerably. Use varchar(max) when the sizes of the column data entries vary considerably, and the size might exceed 8,000 bytes.

There's an interesting discussion on the issue here.

Tip #84: Did you know… How to set a Start page for your Web Site in Visual Web Developer?

Simply right click on the page you want to be the start page and say "set as start page".

As noted in the comment below by Adam Tuliper - MSFT, this only works for debugging, not deployment.

Where you have a posted date in format dd/mm/yyyy, use the below:

$date = explode('/', $_POST['posted_date']);
$new_date = $date[2].'-'.$date[1].'-'.$date[0];

If you have it in mm/dd/yyyy, just change the second line:

$new_date = $date[2].'-'.$date[0].'-'.$date[1];

UPDATE: this was solved by rebooting but there was another error when running app. This time tomcat woudnt start. To solve this (bugs with latest apache and netbeans versions) follow: Error starting Tomcat from NetBeans - '127.0.0.1*' is not recognized as an internal or external command

Most people here seem to be unaware that decimal considers trailing zeroes as significant for storage and printing.

So 0.1m, 0.10m and 0.100m may compare as equal, they are stored differently (as value/scale 1/1, 10/2 and 100/3, respectively), and will be printed as 0.1, 0.10 and 0.100, respectively, by ToString().

As such, the solutions that report "too high a precision" are actually reporting the correct precision, on decimal's terms.

In addition, math-based solutions (like multiplying by powers of 10) will likely be very slow (decimal is ~40x slower than double for arithmetic, and you don't want to mix in floating-point either because that's likely to introduce imprecision). Similarly, casting to int or long as a means of truncating is error-prone (decimal has a much greater range than either of those - it's based around a 96-bit integer).

While not elegant as such, the following will likely be one of the fastest way to get the precision (when defined as "decimal places excluding trailing zeroes"):

public static int PrecisionOf(decimal d) {
  var text = d.ToString(System.Globalization.CultureInfo.InvariantCulture).TrimEnd('0');
  var decpoint = text.IndexOf('.');
  if (decpoint < 0)
    return 0;
  return text.Length - decpoint - 1;
}

The invariant culture guarantees a '.' as decimal point, trailing zeroes are trimmed, and then it's just a matter of seeing of how many positions remain after the decimal point (if there even is one).

Edit: changed return type to int

You could try using FontAwesome. It contains a sort-icon (http://fontawesome.io/icon/sort/).

To do so, you would

1. need to include fontawesome:

   <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">
   

2. and then simply use the fontawesome-icon instead of the default-bootstrap-icons in your th's:

   <th><b>#</b> <i class="fa fa-fw fa-sort"></i></th>
   

Hope that helps.

I wrote bash script for that. Just run it with 2 parameters (database name, dir to store files).

#!/bin/bash

if [ ! $1 ]; then
        echo " Example of use: $0 database_name [dir_to_store]"
        exit 1
fi
db=$1
out_dir=$2
if [ ! $out_dir ]; then
        out_dir="./"
else
        mkdir -p $out_dir
fi

tmp_file="fadlfhsdofheinwvw.js"
echo "print('_ ' + db.getCollectionNames())" > $tmp_file
cols=`mongo $db $tmp_file | grep '_' | awk '{print $2}' | tr ',' ' '`
for c in $cols
do
    mongoexport -d $db -c $c -o "$out_dir/exp_${db}_${c}.json"
done
rm $tmp_file

All answers are old, I recommend and I am a big fan of requests

From homepage:

Python’s standard urllib2 module provides most of the HTTP capabilities you need, but the API is thoroughly broken. It was built for a different time — and a different web. It requires an enormous amount of work (even method overrides) to perform the simplest of tasks.

Things shouldn't be this way. Not in Python.

You use it in situations where you need to create a class for a specific purpose inside another function, e.g., as a listener, as a runnable (to spawn a thread), etc.

The idea is that you call them from inside the code of a function so you never refer to them elsewhere, so you don't need to name them. The compiler just enumerates them.

They are essentially syntactic sugar, and should generally be moved elsewhere as they grow bigger.

I'm not sure if it is one of the advantages of Java, though if you do use them (and we all frequently use them, unfortunately), then you could argue that they are one.

Edited: Kindly note that
whereBetween('date',$start_date,$end_date)
is inclusive of the first date.

final Date currentTime = new Date();
final SimpleDateFormat sdf = new SimpleDateFormat("EEE, MMM d, yyyy hh:mm:ss a z");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println("UTC time: " + sdf.format(currentTime));

Right click on the particular element (e.g. div, table, td) and select the copy as html.

For a while, I specified "constants" (which still weren't actually constants) in object literals passed through to with() statements. I thought it was so clever. Here's an example:

with ({
    MY_CONST : 'some really important value'
}) {
    alert(MY_CONST);
}

In the past, I also have created a CONST namespace where I would put all of my constants. Again, with the overhead. Sheesh.

Now, I just do var MY_CONST = 'whatever'; to KISS.

$('#demoTable td').contents().each(function() {
    if (this.nodeType === 3) {
        this.textContent
        ? this.textContent = 'The text has been '
        : this.innerText  = 'The text has been '
    } else {
        this.innerHTML = 'changed';
        return false;
    }
})

First approach with Windows Service is not easy..

A long time ago, I wrote a C# service.

This is the logic of the Service class (tested, works fine):

namespace MyServiceApp
{
    public class MyService : ServiceBase
    {
        private System.Timers.Timer timer;

        protected override void OnStart(string[] args)
        {
            this.timer = new System.Timers.Timer(30000D);  // 30000 milliseconds = 30 seconds
            this.timer.AutoReset = true;
            this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
            this.timer.Start();
        }

        protected override void OnStop()
        {
            this.timer.Stop();
            this.timer = null;
        }

        private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            MyServiceApp.ServiceWork.Main(); // my separate static method for do work
        }

        public MyService()
        {
            this.ServiceName = "MyService";
        }

        // service entry point
        static void Main()
        {
            System.ServiceProcess.ServiceBase.Run(new MyService());
        }
    }
}

I recommend you write your real service work in a separate static method (why not, in a console application...just add reference to it), to simplify debugging and clean service code.

Make sure the interval is enough, and write in log ONLY in OnStart and OnStop overrides.

Hope this helps!

For PowerShell 3.0 users - following works for both modules and script files:

Please see what the update-alternatives command does (it has a nice man...).

Shortly - what happens when you have java-sun-1.4 and java-opensouce-1.0 ... which one takes "java"? It debian "/usr/bin/java" is symbolic link and "/usr/bin/java-sun-1.4" is an alternative to "/usr/bin/java"

Edit: As Richard said, update-alternatives is not enough. You actually need to use update-java-alternatives. More info at:

As I can see the array is of String only.For each loop can be used to get individual element of the array and put them in local inner class for use.

Below is the code snippet for it :

     //WorkAround 
    for (String color : colors ){

String pos = Character.toUpperCase(color.charAt(0)) + color.substring(1);
JMenuItem Jmi =new JMenuItem(pos);
Jmi.setIcon(new IconA(color));

Jmi.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            JMenuItem item = (JMenuItem) e.getSource();
            IconA icon = (IconA) item.getIcon();
            // HERE YOU USE THE String color variable and no errors!!!
            Color kolorIkony = getColour(color); 
            textArea.setForeground(kolorIkony);
        }
    });

    mnForeground.add(Jmi);
}

}

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

(this question is a duplicate of In chart.js, Is it possible to hide x-axis label/text of bar chart if accessing from mobile?) They added the option, 2.1.4 (and maybe a little earlier) has it

var myLineChart = new Chart(ctx, {
    type: 'line',
    data: data,
    options: {
        scales: {
            xAxes: [{
                ticks: {
                    display: false
                }
            }]
        }
    }
}

In response to Mike B, I prefer to use 'class' as, within a template, 'typename' has an overloaded meaning, but 'class' does not. Take this checked integer type example:

template <class IntegerType>
class smart_integer {
public: 
    typedef integer_traits<Integer> traits;
    IntegerType operator+=(IntegerType value){
        typedef typename traits::larger_integer_t larger_t;
        larger_t interm = larger_t(myValue) + larger_t(value); 
        if(interm > traits::max() || interm < traits::min())
            throw overflow();
        myValue = IntegerType(interm);
    }
}

larger_integer_t is a dependent name, so it requires 'typename' to preceed it so that the parser can recognize that larger_integer_t is a type. class, on the otherhand, has no such overloaded meaning.

That... or I'm just lazy at heart. I type 'class' far more often than 'typename', and thus find it much easier to type. Or it could be a sign that I write too much OO code.

The .join() function is using the index of the passed as argument dataset, so you should use set_index or use .merge function instead.

Please find the two examples that should work in your case:

join_df = LS_sgo.join(MSU_pi.set_index('mukey'), on='mukey', how='left')

or

join_df = df_a.merge(df_b, on='mukey', how='left')
