Your method signature is:

- (void) myTest:(NSString *)

withAString happens to be the parameter (the name is misleading, it looks like it is part of the selector's signature).

If you call the function in this manner:

[self performSelector:@selector(myTest:) withObject:myString];

It will work.

But, as the other posters have suggested, you may want to rename the method:

- (void)myTestWithAString:(NSString*)aString;

And call:

[self performSelector:@selector(myTestWithAString:) withObject:myString];

Change your append calls to say

...append(iter->first)

and

... append(iter->second)

Additionally, the line

std::string* strToReturn = new std::string("");

allocates a string on the heap. If you intend to actually return a pointer to this dynamically allocated string, the return should be changed to std::string*.

Alternatively, if you don't want to worry about managing that object on the heap, change the local declaration to

std::string strToReturn("");

and change the 'append' calls to use reference syntax...

strToReturn.append(...)

instead of

strToReturn->append(...)

Be aware that this will construct the string on the stack, then copy it into the return variable. This has performance implications.

I suggest using RegExp .test() function to check for a pattern match, and the only thing you need to change is remove the start/end of line anchors (and the * quantifier is also redundant) in the regex:

var format = /[ `!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;_x000D_
//            ^                                       ^   _x000D_
document.write(format.test("My@string-with(some%text)") + "<br/>");_x000D_
document.write(format.test("My string with spaces") + "<br/>");_x000D_
document.write(format.test("MyStringContainingNoSpecialChars"));

The anchors (like ^ start of string/line, $ end od string/line and \b word boundaries) can restrict matches at specific places in a string. When using ^ the regex engine checks if the next subpattern appears right at the start of the string (or line if /m modifier is declared in the regex). Same case with $: the preceding subpattern should match right at the end of the string.

In your case, you want to check the existence of the special character from the set anywhere in the string. Even if it is only one, you want to return false. Thus, you should remove the anchors, and the quantifier *. The * quantifier would match even an empty string, thus we must remove it in order to actually check for the presence of at least 1 special character (actually, without any quantifiers we check for exactly one occurrence, same as if we were using {1} limiting quantifier).

What characters are "special" for you?

• All chars other than ASCII chars: /[^\x00-\x7F]/ (demo)
• All chars other than printable ASCII chars: /[^ -~]/ (demo)
• Any printable ASCII chars other than space, letters and digits: /[!-\/:-@[-`{-~]/ (demo)
• Any Unicode punctuation proper chars, the \p{P} Unicode property class:

We are doing ...

ENV http_proxy http://9.9.9.9:9999
ENV https_proxy http://9.9.9.9:9999

and at end of dockerfile ...

ENV http_proxy ""
ENV https_proxy ""

This, for now (until docker introduces build env vars), allows the proxy env vars to be used for the build ONLY without exposing them

The alternative to solution is NOT to build your images locally behind a proxy but to let docker build your images for you using docker "automated builds". Since docker is not building the images behind your proxy the problem is solved. An example of an automated build is available at ...

https://github.com/danday74/docker-nginx-lua (GITHUB repo)

https://registry.hub.docker.com/u/danday74/nginx-lua (DOCKER repo which is watching the github repo using an automated build and doing a docker build on a push to the github master branch)

You can also do cd ......\ as many times as there are folders that takes you to home directory. For example, if you are in cd:\windows\syatem32, then cd ....\ takes you to the home, that is c:\

The source element as a jQuery object should be obtained via

var $el = $(event.target);

This gets you the source of the click, rather than the element that the click function was assigned too. Can be useful when the click event is on a parent object EG.a click event on a table row, and you need the cell that was clicked

$("tr").click(function(event){
    var $td = $(event.target);
});

adb backup will write an Android-specific archive:

adb backup  -f myAndroidBackup.ab  com.corp.appName

This archive can be converted to tar format using:

dd if=myAndroidBackup.ab bs=4K iflag=skip_bytes skip=24 | openssl zlib -d > myAndroidBackup.tar

Reference:

http://nelenkov.blogspot.ca/2012/06/unpacking-android-backups.html

Search for "Update" at that link.

Alternatively, use Android backup extractor to extract files from the Android backup (.ab) file.

I had problems with this and this is the story (sad but true) :

1. If your table name is all lower case like : accounts you can use: select * from AcCounTs and it will work fine

2. If your table name is all lower case like : accounts The following will fail: select * from "AcCounTs"

3. If your table name is mixed case like : Accounts The following will fail: select * from accounts

4. If your table name is mixed case like : Accounts The following will work OK: select * from "Accounts"

I dont like remembering useless stuff like this but you have to ;)

Unfortunately, there is no :click pseudo selector. If you want to change styling on click, you should use Jquery/Javascript. It certainly is better than the "hack" for pure HTML / CSS. But if you insist...

input {_x000D_
display: none;_x000D_
}_x000D_
span {_x000D_
padding: 20px;_x000D_

}_x000D_
input:checked + span {_x000D_

}

  <label for="input">_x000D_
  <input id="input" type="radio" />_x000D_
  <span>NO JS styling</span>_x000D_

Or, if you prefer, you can toggle the styling:

}_x000D_
span {_x000D_
padding: 20px;_x000D_

jminix is an embedded web based JMX console. Not sure if it's maintained any longer, but still.

That's because you're using a non-blocking socket and the output buffer is full.

From the send() man page

   When the message does not fit into  the  send  buffer  of  the  socket,
   send() normally blocks, unless the socket has been placed in non-block-
   ing I/O mode.  In non-blocking mode it  would  return  EAGAIN  in  this
   case.  

EAGAIN is the error code tied to "Resource temporarily unavailable"

Consider using select() to get a better control of this behaviours

Simply add this in your layout for the EditText :

android:textColorHint="#FFFFFF"

The simplest way to put an image into a button:

<button onclick="myFunction()"><img src="your image name here.png"></button>

This will automatically resize the button to the size of the image.

There are several helpful bits of code for this.

Place your cursor in a merged cell and ask these questions in the Immidiate Window:

Is the activecell a merged cell?

? Activecell.Mergecells
 True

How many cells are merged?

? Activecell.MergeArea.Cells.Count
 2

How many columns are merged?

? Activecell.MergeArea.Columns.Count
 2

How many rows are merged?

? Activecell.MergeArea.Rows.Count
  1

What's the merged range address?

? activecell.MergeArea.Address
  $F$2:$F$3

Angular 2-4 route reload hack

For me, using this method inside a root component (component, which is present on any route) works:

onRefresh() {
  this.router.routeReuseStrategy.shouldReuseRoute = function(){return false;};

  let currentUrl = this.router.url + '?';

  this.router.navigateByUrl(currentUrl)
    .then(() => {
      this.router.navigated = false;
      this.router.navigate([this.router.url]);
    });
  }

Here is how I did it:

CSS:

.my-flex-card > div > div.card {
    height: calc(100% - 15px);
    margin-bottom: 15px;
}

HTML:

<div class="row my-flex-card">
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                aaaa
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                bbbb
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                cccc
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                dddd
            </div>
        </div>
    </div>
</div>

select count(*) 
from table_emp 
 where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'

None, False and True all are available within template tags and filters. None, False, the empty string ('', "", """""") and empty lists/tuples all evaluate to False when evaluated by if, so you can easily do

{% if profile.user.first_name == None %}
{% if not profile.user.first_name %}

A hint: @fabiocerqueira is right, leave logic to models, limit templates to be the only presentation layer and calculate stuff like that in you model. An example:

# someapp/models.py
class UserProfile(models.Model):
    user = models.OneToOneField('auth.User')
    # other fields

    def get_full_name(self):
        if not self.user.first_name:
            return
        return ' '.join([self.user.first_name, self.user.last_name])

# template
{{ user.get_profile.get_full_name }}

Hope this helps :)

From a posting by Matz:

(1) ++ and -- are NOT reserved operator in Ruby.

(2) C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.

(3) self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.

                      matz.

Or, you could try changing the parameter type to string, then convert the string to an integer in the method. I am new to MVC, but I believe you need nullable objects in your parameter list, how else will the controller indicate that no such parameter was provided? So...

public ActionResult ViewNextItem(string id)...

I've recently stumbled upon the following solution to this problem:

Source: Multiple versions of Chrome

...this is registry data problem: How to do it then (this is an example for 2.0.172.39 and 3.0.197.11, I'll try it with next versions as they will come, let's assume I've started with Chrome 2):

1. Install Chrome 2, you'll find it Application Data folder, since I'm from Czech Republic and my name is Bronislav Klucka the path looks like this:

   C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome
   

   and run Chrome

2. Open registry and save

   [HKEY_CURRENT_USER\Software\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   [HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   

   keys, put them into one chrome2.reg file and copy this file next to chrome.exe (ChromeDir\Application)

3. Rename Chrome folder to something else (e.g. Chrome2)

4. Install Chrome 3, it will install to Chrome folder again and run Chrome

5. Save the same keys (there are changes due to different version) and save it to the chrome3.reg file next to chrome.exe file of this new version again

6. Rename the folder again (e.g. Chrome3)

   the result would be that there is no Chrome dir (only Chrome2 and Chrome3)

7. Go to the Application folder of Chrome2, create chrome.bat file with this content:

   @echo off
   regedit /S chrome2.reg
   START chrome.exe -user-data-dir="C:\Docume~1\Bronis~1\LocalS~1\Dataap~1\Google\Chrome2\User Data"
   rem START chrome.exe -user-data-dir="C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome2\User Data"
   

   the first line is generic batch command, the second line will update registry with the content of chrome2.reg file, the third lines starts Chrome pointing to passed directory, the 4th line is commented and will not be run.

   Notice short name format passed as -user-data-dir parameter (the full path is at the 4th line), the problem is that Chrome using this parameter has a problem with diacritics (Czech characters)

8. Do 7. again for Chrome 3, update paths and reg file name in bat file for Chrome 3

Try running both bat files, seems to be working, both versions of Chrome are running simultaneously.

Updating: Running "About" dialog displays correct version, but an error while checking for new one. To correct that do (I'll explain form Chrome2 folder): 1. rename Chrome2 to Chrome 2. Go to Chrome/Application folder 3. run chrome2.reg file 4. run chrome.exe (works the same for Chrome3) now the version checking works. There has been no new version of Chrome since I've find this whole solution up. But I assume that update will be downloaded to this folder so all you need to do is to update reg file after update and rename Chrome folder back to Chrome2. I'll update this post after successful Chrome update.

One user control can't be applied to it ownself. So open another winform and the one will appear in the toolbox.

By default, Jenkins account is created without password and with the login shell as /bin/false.

jenkins:x:496:493:Jenkins Continuous Integration Server:/var/lib/jenkins:/bin/false

Change the shell to /bin/bash and you should be able to login without password by sudo su - jenkins.

Command to change the shell is:

chsh -s /bin/bash jenkin

I would think that one reason could be that the color is applied to things other than font. For example:

div {
    border: 1px solid;
    color: red;
}

Yields both a red font color and a red border.

Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.

I also faced problem in .Net Remoting Service in C#.

I got it solved in 3 steps:

1. Change Port of Protocol in all the files whereever it is being used.
2. Run your Host Server Program and make it active.
3. Now run your client program.

Just use a normal Javascript expression, no {} or anything necessary:

@click="addToCount(item.contactID)"

if you also need the event object:

@click="addToCount(item.contactID, $event)"

Command go

Download and install packages and dependencies

Usage:

go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]

Get downloads the packages named by the import paths, along with their dependencies. It then installs the named packages, like 'go install'.

The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages.

The -f flag, valid only when -u is set, forces get -u not to verify that each package has been checked out from the source control repository implied by its import path. This can be useful if the source is a local fork of the original.

The -fix flag instructs get to run the fix tool on the downloaded packages before resolving dependencies or building the code.

The -insecure flag permits fetching from repositories and resolving custom domains using insecure schemes such as HTTP. Use with caution.

The -t flag instructs get to also download the packages required to build the tests for the specified packages.

The -u flag instructs get to use the network to update the named packages and their dependencies. By default, get uses the network to check out missing packages but does not use it to look for updates to existing packages.

The -v flag enables verbose progress and debug output.

Get also accepts build flags to control the installation. See 'go help build'.

When checking out a new package, get creates the target directory GOPATH/src/. If the GOPATH contains multiple entries, get uses the first one. For more details see: 'go help gopath'.

When checking out or updating a package, get looks for a branch or tag that matches the locally installed version of Go. The most important rule is that if the local installation is running version "go1", get searches for a branch or tag named "go1". If no such version exists it retrieves the default branch of the package.

When go get checks out or updates a Git repository, it also updates any git submodules referenced by the repository.

Get never checks out or updates code stored in vendor directories.

For more about specifying packages, see 'go help packages'.

For more about how 'go get' finds source code to download, see 'go help importpath'.

This text describes the behavior of get when using GOPATH to manage source code and dependencies. If instead the go command is running in module-aware mode, the details of get's flags and effects change, as does 'go help get'. See 'go help modules' and 'go help module-get'.

See also: go build, go install, go clean.

For example, showing verbose output,

$ go get -v github.com/capotej/groupcache-db-experiment/...
github.com/capotej/groupcache-db-experiment (download)
github.com/golang/groupcache (download)
github.com/golang/protobuf (download)

Without knowing the ID of the DIV I think you could select the IMG like this:

$("#"+$(this).attr("id")+" img:first")

Starting in Python 3.7, you can use the breakpoint() built-in function to enter the debugger:

foo()
breakpoint()  # drop into the debugger at this point
bar()

By default, breakpoint() will import pdb and call pdb.set_trace(). However, you can control debugging behavior via sys.breakpointhook() and use of the environment variable PYTHONBREAKPOINT.

See PEP 553 for more information.

Other answers didn't mention how to access battery status (chraging or not).

IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, ifilter);

// Are we charging / charged?
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
                     status == BatteryManager.BATTERY_STATUS_FULL;

// How are we charging?
int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;

This related question's answer provided the solution for me... it was just a dumb mistake:

Remember to commit first!

https://stackoverflow.com/a/7572252

If you have not yet committed to your local repo, there is nothing to push, but the Git error message you get back doesn't help you too much.

Basically NS comes from NextSTEP, the original operating system that became Mac OS X when Apple acquired Next.

I want to explain something else and this is why exactly it's needed.

In C++ there are namespaces and almost anything goes in std

This is why you have std::string.

Namespaces are used so it's harder for you to make a mistake and you can write your own class string without conflicting with the system one.

Objective-C is superset of C, but it doesn't include namespaces and for the same reason above all system classes are prefixed with NS or some other strange prefix.

This thing is the same of how all DirectX classes are prefixed with D3D and how all OpenGL classes are prefixed with gl.

This means that you should not use NS to name your own classes and when you see NS, CA in Core Animation or CG in Core Graphics you understand that this is a call to a system framework.

Swift changes this convention, because Swift supports namespacing and it maps its core types like String to the NS equivalents.

It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:

1. Implement a separate session store for socket.io that stores data in the same format as connect-redis
2. Make connect session cookie not http-only so it's accessible from client JS
3. Upon a socket.io connection, send session cookie over socket.io from browser to server
4. Store the session id in a socket.io connection, and use it to access session data from redis.

If you use the following CSS

<link href="~/Content/common/bootstrap.css" rel="stylesheet" type="text/css"    />
<link href="~/Content/common/bootstrap.min.css" rel="stylesheet" type="text/css" />
<link href="~/Content/common/site.css" rel="stylesheet" type="text/css" />

just change it into the following style by adding media="screen"

<link href="~/Content/common/bootstrap.css" rel="stylesheet" **media="screen"** type="text/css" />
<link href="~/Content/common/bootstrap.min.css" rel="stylesheet" **media="screen"** type="text/css" />
<link href="~/Content/common/site.css" rel="stylesheet" **media="screen"** type="text/css" />

I think it will work.

the former answers like

    @media print {
  a[href]:after {
    content: none !important;
  }
}

were not worked well in the chrome browse.

I know this topic is a bit old, but after struggling and waiting a lot to download, Ive changed my DNS settings to use google's one (4.4.4.4 and 8.8.8.8) and it worked!!

My connection is 30mbps from Brazil (Virtua), using isp's provider I was getting 80KB/s and after changing to google dns, I got 2MB/s average.

All you need to do is set these properties in your theme

<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>

You did not specify any time stamp or interval for how long you would require such output, so I considered it to be an infinite loop. You can change it accordingly as per your need.

while true
do
   echo -e "`date`|`ping -n -c 1 <IP_TO_PING>|grep 'bytes from'`"
   sleep 2
done

In the format property of any textbox field you can use format strings:

e.g. D/M/Y, D, etc.

CREATE TABLE Admission (
    Rno INT PRIMARY KEY AUTO_INCREMENT,
    Name VARCHAR(25) NOT NULL,
    Gender ENUM('M','F'),
    Boolean_Valu boolean,
    Dob Date,
    Fees numeric(7,2) NOT NULL
);




insert into Admission (Name,Gender,Boolean_Valu,Dob,Fees)values('Raj','M',true,'1990-07-12',50000);
insert into Admission (Name,Gender,Boolean_Valu,Dob,Fees)values('Rani','F',false,'1994-05-10',15000);
select * from admission;

You can use ES6 spread on previous values in the object to avoid overwrite

this.setState({
     abc: {
            ...this.state.abc,
            xyz: 'new value'
           }
});

I created a PS script to check idle time and jiggle the mouse to prevent the screensaver.

There are two parameters you can control how it works.

$checkIntervalInSeconds : the interval in seconds to check if the idle time exceeds the limit

$preventIdleLimitInSeconds : the idle time limit in seconds. If the idle time exceeds the idle time limit, jiggle the mouse to prevent the screensaver

Here we go. Save the script in preventIdle.ps1. For preventing the 4-min screensaver, I set $checkIntervalInSeconds = 30 and $preventIdleLimitInSeconds = 180.

The best and most intuitive way is to use serialEvent() callback Arduino defines along with loop() and setup().

I've built a small library a while back that handles message reception, but never had time to opensource it. This library receives \n terminated lines that represent a command and arbitrary payload, space-separated. You can tweak it to use your own protocol easily.

First of all, a library, SerialReciever.h:

#ifndef __SERIAL_RECEIVER_H__
#define __SERIAL_RECEIVER_H__
    
class IncomingCommand {
  private:
    static boolean hasPayload;
  public:
    static String command;
    static String payload;
    static boolean isReady;
    static void reset() {
      isReady = false;
      hasPayload = false;
      command = "";
      payload = "";
    }
    static boolean append(char c) {
      if (c == '\n') {
        isReady = true;
        return true;
      }
      if (c == ' ' && !hasPayload) {
        hasPayload = true;
        return false;
      }
      if (hasPayload)
        payload += c;
      else
        command += c;
      return false;
    }
};
    
boolean IncomingCommand::isReady = false;
boolean IncomingCommand::hasPayload = false;
String IncomingCommand::command = false;
String IncomingCommand::payload = false;
    
#endif // #ifndef __SERIAL_RECEIVER_H__

To use it, in your project do this:

#include <SerialReceiver.h>
    
void setup() {
  Serial.begin(115200);
  IncomingCommand::reset();
}
    
void serialEvent() {
  while (Serial.available()) {
    char inChar = (char)Serial.read();
    if (IncomingCommand::append(inChar))
      return;
  }
}

To use the received commands:

void loop() {
  if (!IncomingCommand::isReady) {
    delay(10);
    return;
  }

executeCommand(IncomingCommand::command, IncomingCommand::payload); // I use registry pattern to handle commands, but you are free to do whatever suits your project better.
    
IncomingCommand::reset();

Explanation

I'm not sure if my answer is direct answer to original question, but as I suppose a lot of people come here to just find a way to tell their IDEs to understand types, I'll share what I found.

If you want to tell VSCode to understand your types, do as follows. Please pay attention that js runtime and NodeJS does not care about these types at all.

Solution

1- Create a file with .d.ts ending: e.g: index.d.ts. You can create this file in another folder. for example: types/index.d.ts
2- Suppose we want to have a function called view. Add these lines to index.d.ts:

/**
 * Use express res.render function to render view file inside layout file.
 *
 * @param {string} view The path of the view file, relative to view root dir.
 * @param {object} options The options to send to view file for ejs to use when rendering.
 * @returns {Express.Response.render} .
 */
view(view: string, options?: object): Express.Response.render;

3- Create a jsconfig.json file in you project's root. (It seems that just creating this file is enough for VSCode to search for your types).

A bit more

Now suppose we want to add this type to another library types. (As my own situation). We can use some ts keywords. And as long as VSCode understands ts we have no problem with it.
For example if you want to add this view function to response from expressjs, change index.d.ts file as follows:

export declare global {
  namespace Express {
    interface Response {
      /**
       * Use express res.render function to render view file inside layout file.

I own a mac too! here is the code that will work:

myButton.setBackground(Color.RED);
myButton.setOpaque(true); //Sets Button Opaque so it works

before doing anything or adding any components set the look and feel so it looks better:

try{
   UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
 }catch(Exception e){
  e.printStackTrace(); 
 }

That is Supposed to change the look and feel to the cross platform look and feel, hope i helped! :)

A Type agnostic solution:

for _, key := range reflect.ValueOf(yourMap).MapKeys() {
    value := s.MapIndex(key).Interface()
    fmt.Println("Key:", key, "Value:", value)
}

http://docs.python.org/2/tutorial/classes.html#method-objects

Usually, a method is called right after it is bound:

x.f()

In the MyClass example, this will return the string 'hello world'. However, it is not necessary to call a method right away: x.f is a method object, and can be stored away and called at a later time. For example:

xf = x.f
while True:
    print xf()

will continue to print hello world until the end of time.

What exactly happens when a method is called? You may have noticed that x.f() was called without an argument above, even though the function definition for f() specified an argument. What happened to the argument? Surely Python raises an exception when a function that requires an argument is called without any — even if the argument isn’t actually used...

Actually, you may have guessed the answer: the special thing about methods is that the object is passed as the first argument of the function. In our example, the call x.f() is exactly equivalent to MyClass.f(x). In general, calling a method with a list of n arguments is equivalent to calling the corresponding function with an argument list that is created by inserting the method’s object before the first argument.

If you still don’t understand how methods work, a look at the implementation can perhaps clarify matters. When an instance attribute is referenced that isn’t a data attribute, its class is searched. If the name denotes a valid class attribute that is a function object, a method object is created by packing (pointers to) the instance object and the function object just found together in an abstract object: this is the method object. When the method object is called with an argument list, a new argument list is constructed from the instance object and the argument list, and the function object is called with this new argument list.

you can use multiple attribute

 <OPTION VALUE="1"> One  
 <OPTION VALUE="2"> Two  
 <OPTION VALUE="3"> Three

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"

Below is the simplest way

Try the code

ALTER TRIGGER trigger_name DISABLE

That's it :)

I just added a hidden attribute in an option like below. It is working fine for me.

<select>_x000D_
  <option hidden>Sex</option>_x000D_
  <option>Male</option>_x000D_
  <option>Female</option>_x000D_
</select>

I also noticed that the query

SELECT * FROM tablename;

gives an error on the psql command prompt and

SELECT * FROM "tablename";

runs fine, really strange, so don't forget the double quotes. I always liked databases :-(

No, there isn't such constant.

The above answers are all fine, but the essence of the issue is that some headers are set one way, and others are set other ways. See above for 'restricted header' lists. FOr these, you just set them as a property. For others, you actually add the header. See here.

    request.ContentType = "application/x-www-form-urlencoded";

    request.Accept = "application/json";

    request.Headers.Add(HttpRequestHeader.Authorization, "Basic " + info.clientId + ":" + info.clientSecret);

Yes, just add multiple FileAppenders to your logger. For example:

<log4net>
    <appender name="File1Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-1.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>
    <appender name="File2Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-2.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="File1Appender" />
        <appender-ref ref="File2Appender" />
    </root>
</log4net>

Use the DecimalFormat class to format the double

AffineTransformOp offers the additional flexibility of choosing the interpolation type.

BufferedImage before = getBufferedImage(encoded);
int w = before.getWidth();
int h = before.getHeight();
BufferedImage after = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
AffineTransform at = new AffineTransform();
at.scale(2.0, 2.0);
AffineTransformOp scaleOp = 
   new AffineTransformOp(at, AffineTransformOp.TYPE_BILINEAR);
after = scaleOp.filter(before, after);

The fragment shown illustrates resampling, not cropping; this related answer addresses the issue; some related examples are examined here.

You can't use named parameters in JDBC itself. You could try using Spring framework, as it has some extensions that allow the use of named parameters in queries.

I have nothing against:

Array.apply(null, Array(5)).map(Number.prototype.valueOf,0);
new Array(5+1).join('0').split('').map(parseFloat);

suggested by Zertosh, but in a new ES6 array extensions allow you to do this natively with fill method. Now IE edge, Chrome and FF supports it, but check the compatibility table

new Array(3).fill(0) will give you [0, 0, 0]. You can fill the array with any value like new Array(5).fill('abc') (even objects and other arrays).

On top of that you can modify previous arrays with fill:

arr = [1, 2, 3, 4, 5, 6]
arr.fill(9, 3, 5)  # what to fill, start, end

which gives you: [1, 2, 3, 9, 9, 6]

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

from json.decoder import JSONDecodeError


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

//EDIT (Oct 2020):

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

from json.decoder import JSONDecodeError


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

$("#myid li").click(function() {
    alert(this.id); // id of clicked li by directly accessing DOMElement property
    alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
    alert($(this).html()); // gets innerHTML of clicked li
    alert($(this).text()); // gets text contents of clicked li
});

If you are talking about replacing the ID with something:

$("#myid li").click(function() {
    this.id = 'newId';

    // longer method using .attr()
    $(this).attr('id', 'newId');
});

Demo here. And to be fair, you should have first tried reading the documentation:

• http://api.jquery.com/category/selectors/
• http://api.jquery.com/category/events/
• http://api.jquery.com/attr/

I'll try to answer all your questions by addressing the larger question: How can I sync data between a webserver and an android app?

Syncing data between your webserver and an android app requires a couple of different components on your android device.

Persistent Storage:

This is how your phone actually stores the data it receives from the webserver. One possible method for accomplishing this is writing your own custom ContentProvider backed by a Sqlite database. A decent tutorial for a content provider can be found here: http://thinkandroid.wordpress.com/2010/01/13/writing-your-own-contentprovider/

A ContentProvider defines a consistent interface to interact with your stored data. It could also allow other applications to interact with your data if you wanted. Behind your ContentProvider could be a Sqlite database, a Cache, or any arbitrary storage mechanism.

While I would certainly recommend using a ContentProvider with a Sqlite database you could use any java based storage mechanism you wanted.

Data Interchange Format:

This is the format you use to send the data between your webserver and your android app. The two most popular formats these days are XML and JSON. When choosing your format, you should think about what sort of serialization libraries are available. I know off-hand that there's a fantastic library for json serialization called gson: https://github.com/google/gson, although I'm sure similar libraries exist for XML.

Synchronization Service

You'll want some sort of asynchronous task which can get new data from your server and refresh the mobile content to reflect the content of the server. You'll also want to notify the server whenever you make local changes to content and want to reflect those changes. Android provides the SyncAdapter pattern as a way to easily solve this pattern. You'll need to register user accounts, and then Android will perform lots of magic for you, and allow you to automatically sync. Here's a good tutorial: http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/

As for how you identify if the records are the same, typically you'll create items with a unique id which you store both on the android device and the server. You can use that to make sure you're referring to the same reference. Furthermore, you can store column attributes like "updated_at" to make sure that you're always getting the freshest data, or you don't accidentally write over newly written data.

You save some bytes by avoiding the .attr altogether by passing the properties to the jQuery constructor:

var img = $('<img />',
             { id: 'Myid',
               src: 'MySrc.gif', 
               width: 300
             })
              .appendTo($('#YourDiv'));

Maybe you mean

select x
from some_table
where some_column is null or some_column = ''

but I can't tell since you didn't really ask a question.

export default affects the syntax when importing the exported "thing", when allowing to import, whatever has been exported, by choosing the name in the import itself, no matter what was the name when it was exported, simply because it's marked as the "default".

A useful use case, which I like (and use), is allowing to export an anonymous function without explicitly having to name it, and only when that function is imported, it must be given a name:

Example:

Export 2 functions, one is default:

export function divide( x ){
    return x / 2;
}

// only one 'default' function may be exported and the rest (above) must be named
export default function( x ){  // <---- declared as a default function
    return x * x;
}

Import the above functions. Making up a name for the default one:

// The default function should be the first to import (and named whatever)
import square, {divide} from './module_1.js'; // I named the default "square" 

console.log( square(2), divide(2) ); // 4, 1

When the {} syntax is used to import a function (or variable) it means that whatever is imported was already named when exported, so one must import it by the exact same name, or else the import wouldn't work.

Erroneous Examples:

1. The default function must be first to import

   import {divide}, square from './module_1.js
   

2. divide_1 was not exported in module_1.js, thus nothing will be imported

   import {divide_1} from './module_1.js
   

3. square was not exported in module_1.js, because {} tells the engine to explicitly search for named exports only.

   import {square} from './module_1.js
   

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

This is how I implemented my URL builder. I have created one Service class to provide the params for the URL

public interface ParamsProvider {

    String queryProvider(List<BasicNameValuePair> params);

    String bodyProvider(List<BasicNameValuePair> params);
}

The Implementation of methods are below

@Component
public class ParamsProviderImp implements ParamsProvider {
    @Override
    public String queryProvider(List<BasicNameValuePair> params) {
        StringBuilder query = new StringBuilder();
        AtomicBoolean first = new AtomicBoolean(true);
        params.forEach(basicNameValuePair -> {
            if (first.get()) {
                query.append("?");
                query.append(basicNameValuePair.toString());
                first.set(false);
            } else {
                query.append("&");
                query.append(basicNameValuePair.toString());
            }
        });
        return query.toString();
    }

    @Override
    public String bodyProvider(List<BasicNameValuePair> params) {
        StringBuilder body = new StringBuilder();
        AtomicBoolean first = new AtomicBoolean(true);
        params.forEach(basicNameValuePair -> {
            if (first.get()) {
                body.append(basicNameValuePair.toString());
                first.set(false);
            } else {
                body.append("&");
                body.append(basicNameValuePair.toString());
            }
        });
        return body.toString();
    }
}

When we need the query params for our URL, I simply call the service and build it. Example for that is below.

Class Mock{
@Autowired
ParamsProvider paramsProvider;
 String url ="http://www.google.lk";
// For the query params price,type
 List<BasicNameValuePair> queryParameters = new ArrayList<>();
 queryParameters.add(new BasicNameValuePair("price", 100));
 queryParameters.add(new BasicNameValuePair("type", "L"));
url = url+paramsProvider.queryProvider(queryParameters);
// You can use it in similar way to send the body params using the bodyProvider

}

This simple function works for me:

public static String leftPad(String string, int length, String pad) {
      return pad.repeat(length - string.length()) + string;
    }

Invocation:

String s = leftPad(myString, 10, "0");

pow is built into the language(not part of the math library). The problem is that you haven't imported math.

Try this:

import math
math.sqrt(4)

"You can store as many objects as you want within a bucket, and write, read, and delete objects in your bucket. Objects can be up to 5 terabytes in size."

<style> tags should be places within the <head> element, and each added tag should be added to the bottom of the <head> tag.

Using insertAdjacentHTML to inject a style tag into the document head tag:

Native DOM:

document.head.insertAdjacentHTML("beforeend", `<style>body{background:red}</style>`)

jQuery:

$('<style>').text("body{background:red}").appendTo(document.head)

If you face the problem in Ruby on Rails, the exhaustive solution is provided by Bootstrap Ruby Gem readme file.

or in short:

1. rename application.css to application.scss
2. add @import "bootstrap";
3. add gem 'jquery-rails' to Gemfile unless it exists.
4. add //= require jquery3 //= require popper //= require bootstrap //= require bootstrap-sprockets to application.js.

If you want to log inside JSX you can create a dummy component
which plugs where you wish to log:

const Console = prop => (
  console[Object.keys(prop)[0]](...Object.values(prop))
  ,null // ? React components must return something 
)

// Some component with JSX and a logger inside
const App = () => 
  <div>
    <p>imagine this is some component</p>
    <Console log='foo' />
    <p>imagine another component</p>
    <Console warn='bar' />
  </div>

// Render 
ReactDOM.render(
  <App />,
  document.getElementById("react")
)

<div id="react"></div>

If you're getting a lot of warnings (in my case 64 in a solution!) like

CS0618: 'ConfigurationSettings.AppSettings' is obsolete: 'This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings'

because you're upgrading an older project you can save a lot of time as follows:

1. Add System.Configuration as a reference to your References section.

2. Add the following two using statements to the top of each class (.cs) file:

   using System.Configuration; using ConfigurationSettings = System.Configuration.ConfigurationManager;

By this change all occurances of

ConfigurationSettings.AppSettings["mySetting"]

will now reference the right configuration manager, no longer the deprecated one, and all the CS0618 warnings will go away immediately.

Of course, keep in mind that this is a quick hack. On the long term, you should consider refactoring the code.

This is a simple way of doing something.

    @Override
        public void onBackPressed() {
            // do what you want to do when the "back" button is pressed.
            startActivity(new Intent(Activity.this, MainActivity.class));
            finish();
        }

I think there might be more elaborate ways of going about it, but I like simplicity. For example, I used the template above to make the user sign out of the application AND THEN go back to another activity of my choosing.

Here's another method, which happens to use no correlated subqueries or GROUP BY. I'm not expert in PostgreSQL performance tuning, so I suggest you try both this and the solutions given by other folks to see which works better for you.

SELECT l1.*
FROM lives l1 LEFT OUTER JOIN lives l2
  ON (l1.usr_id = l2.usr_id AND (l1.time_stamp < l2.time_stamp 
   OR (l1.time_stamp = l2.time_stamp AND l1.trans_id < l2.trans_id)))
WHERE l2.usr_id IS NULL
ORDER BY l1.usr_id;

I am assuming that trans_id is unique at least over any given value of time_stamp.

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

Minor update in @Joran's code.
Using the code below, you can avoid the ambiguity and only get the unique of two columns:

dat <- data.frame(id=c(1,1,3), id2=c(1,1,4) ,somevalue=c("x","y","z"))    
dat[row.names(unique(dat[,c("id", "id2")])), c("id", "id2")]

this code seems to have address the issue for me. it comes for a streaming class, ergo some of the nomenclature.

You're on the right track. You may read the user input into an integer and switch on that:

enum Choice
{
  EASY = 1, 
  MEDIUM = 2, 
  HARD = 3
};

int i = -1;

// ...<present the user with a menu>...

cin >> i;

switch(i)
{
  case EASY:
    cout << "Easy\n";
    break;
  case MEDIUM:
    cout << "Medium\n";
    break;
  case HARD:
    cout << "Hard\n";
    break;
  default:
    cout << "Invalid Selection\n";
    break;
}

It seems that resource filtering/searching can be implemented in a RESTful way. The idea is to introduce a new endpoint called /filters/ or /api/filters/.

Using this endpoint filter can be considered as a resource and hence created via POST method. This way - of course - body can be used to carry all the parameters as well as complex search/filter structures can be created.

After creating such filter there are two possibilities to get the search/filter result.

1. A new resource with unique ID will be returned along with 201 Created status code. Then using this ID a GET request can be made to /api/users/ like:

   GET /api/users/?filterId=1234-abcd
   

2. After new filter is created via POST it won't reply with 201 Created but at once with 303 SeeOther along with Location header pointing to /api/users/?filterId=1234-abcd. This redirect will be automatically handled via underlying library.

In both scenarios two requests need to be made to get the filtered results - this may be considered as a drawback, especially for mobile applications. For mobile applications I'd use single POST call to /api/users/filter/.

How to keep created filters?

They can be stored in DB and used later on. They can also be stored in some temporary storage e.g. redis and have some TTL after which they will expire and will be removed.

What are the advantages of this idea?

Filters, filtered results are cacheable and can be even bookmarked.

In case you have Git installed,

you can open the Git Bash (shift pressed + right click in the folder -> Git Bash Here) and use openssl command right in the Bash

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

Try

git checkout <commit hash>
git checkout -b new_branch

The commit should only exist once in your tree, not in two separate branches.

This allows you to check out that specific commit and name it what you will.

String url = "jdbc:mysql://127.0.0.1:3306/yourdatabase";
String user = "username";
String password = "password";

// Load the Connector/J driver
Class.forName("com.mysql.jdbc.Driver").newInstance();
// Establish connection to MySQL
Connection conn = DriverManager.getConnection(url, user, password);

$(window).height();

To set anything in the middle you can use CSS.

<style>
#divCentre 
{ 
    position: absolute;
    left: 50%;
    top: 50%;
    width: 300px;
    height: 400px;
    margin-left: -150px;
    margin-top: -200px;
}
</style>
<div id="divCentre">I am at the centre</div>

Use .modal({show:true}) and .modal({show:false}) instead of ('show') and ('hide') ... it seems to be bootstrap / jquery version combination dependent. Hope it helps.

1. Writing JSON Parser Class

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

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

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

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

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

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

We have similar situation right now and as of this answer, I am using laravel 5.6 release.

I will not use your example in the question but mine, because it's related though.

I have route like this:

Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');

Then in your controller method, make sure you include

use Illuminate\Http\Request;

and this should be above your controller, most likely a default, if generated using php artisan, now to get variable from the url it should look like this:

  public function someMethod(Request $request)
  {
    $foo = $request->input("start");
    $bar = $request->input("limit");

    // some codes here
  }

Regardless of the HTTP verb, the input() method may be used to retrieve user input.

https://laravel.com/docs/5.6/requests#retrieving-input

Hope this help.

This works for both GET and POST:

@Context
private HttpServletRequest httpRequest;


private void printRequest(HttpServletRequest httpRequest) {
    System.out.println(" \n\n Headers");

    Enumeration headerNames = httpRequest.getHeaderNames();
    while(headerNames.hasMoreElements()) {
        String headerName = (String)headerNames.nextElement();
        System.out.println(headerName + " = " + httpRequest.getHeader(headerName));
    }

    System.out.println("\n\nParameters");

    Enumeration params = httpRequest.getParameterNames();
    while(params.hasMoreElements()){
        String paramName = (String)params.nextElement();
        System.out.println(paramName + " = " + httpRequest.getParameter(paramName));
    }

    System.out.println("\n\n Row data");
    System.out.println(extractPostRequestBody(httpRequest));
}

static String extractPostRequestBody(HttpServletRequest request) {
    if ("POST".equalsIgnoreCase(request.getMethod())) {
        Scanner s = null;
        try {
            s = new Scanner(request.getInputStream(), "UTF-8").useDelimiter("\\A");
        } catch (IOException e) {
            e.printStackTrace();
        }
        return s.hasNext() ? s.next() : "";
    }
    return "";
}

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

With:

FILES = $(shell ls)

indented underneath all like that, it's a build command. So this expands $(shell ls), then tries to run the command FILES ....

If FILES is supposed to be a make variable, these variables need to be assigned outside the recipe portion, e.g.:

FILES = $(shell ls)
all:
        echo $(FILES)

Of course, that means that FILES will be set to "output from ls" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ... to avoid this, for efficiency and/or correctness.¹)

If FILES is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:

all:
        FILES="$(shell ls)"

However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:

        FILES="$(shell ls)"; echo $$FILES

This is all a bit silly since the shell will expand * (and other shell glob expressions) for you in the first place, so you can just:

        echo *

as your shell command.

Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls is not completely reliable (some details depend on file names and sometimes even the version of ls; some versions of ls attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard) and $(subst ...) to accomplish everything inside make itself (avoiding any "weird characters in file name" issues). (In sh scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0 to avoid tripping over blanks, newlines, control characters, and so on.)

¹The GNU Make documentation notes further that POSIX make added ::= assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make variants support ::= assignment, although GNU make does today, with the same meaning as :=, i.e., do the assignment right now with expansion.

Note that VAR := $(shell command args...) can also be spelled VAR != command args... in several make variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell) so using VAR != command args... is superior in both being shorter and working in more variants.

You can get the mouse positions by using this snippet:

function getMousePos(canvas, evt) {
    var rect = canvas.getBoundingClientRect();
    return {
        x: (evt.clientX - rect.left) / (rect.right - rect.left) * canvas.width,
        y: (evt.clientY - rect.top) / (rect.bottom - rect.top) * canvas.height
    };
}

This code takes into account both changing coordinates to canvas space (evt.clientX - rect.left) and scaling when canvas logical size differs from its style size (/ (rect.right - rect.left) * canvas.width see: Canvas width and height in HTML5).

If you have a FILE *, you can use functions like fscanf, fprintf and fgets etc. If you have just the file descriptor, you have limited (but likely faster) input and output routines read, write etc.

You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.

Site 1

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';

Includes under site one would be at:

echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';

Site 2

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';

The actual code to access includes from site1 inside of site2 you would say:

include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');

It will only use the relative path of the file executing the query if you try to access it by excluding the document root and the root slash:

 //(not as fool-proof or non-platform specific)
 include('../includes/file_from_site_1.php');

Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.

Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:

<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>

You should use:

<a href='/contact/'>Contact</a>

For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt file for ONLY site1:

User-agent: *
Disallow: /blog/

Other possibilities:

Look up your IP address and include this snippet of code:

function is_dev(){
  //use the external IP from Google.
  //If you're hosting locally it's 127.0.01 unless you've changed it.
  $ip_address='xxx.xxx.xxx.xxx';

  if ($_SERVER['REMOTE_ADDR']==$ip_address){
     return true;
  } else {
     return false;
  } 
}

if(is_dev()){
    echo $_SERVER['DOCUMENT_ROOT'];       
}

Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.

If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:

if(is_dev()){
    echo "<script>".PHP_EOL;
    echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
    echo "</script>".PHP_EOL;       
}

Change

JSONObject objects = getArray.getJSONArray(i);

to

JSONObject objects = getArray.getJSONObject(i);

or to

JSONObject objects = getArray.optJSONObject(i);

depending on which JSON-to/from-Java library you're using. (It looks like getJSONObject will work for you.)

Then, to access the string elements in the "objects" JSONObject, get them out by element name.

String a = objects.get("A");

If you need the names of the elements in the JSONObject, you can use the static utility method JSONObject.getNames(JSONObject) to do so.

String[] elementNames = JSONObject.getNames(objects);

"Get the value for the first element and the value for the last element."

If "element" is referring to the component in the array, note that the first component is at index 0, and the last component is at index getArray.length() - 1.

I want to iterate though the objects in the array and get thier component and thier value. In my example the first object has 3 components, the scond has 5 and the third has 4 components. I want iterate though each of them and get thier component name and value.

The following code does exactly that.

import org.json.JSONArray;
import org.json.JSONObject;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    String jsonInput = "{\"JObjects\":{\"JArray1\":[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\"},{\"A\":\"a1\",\"B\":\"b2\",\"C\":\"c3\",\"D\":\"d4\",\"E\":\"e5\"},{\"A\":\"aa\",\"B\":\"bb\",\"C\":\"cc\",\"D\":\"dd\"}]}}";

    // "I want to iterate though the objects in the array..."
    JSONObject outerObject = new JSONObject(jsonInput);
    JSONObject innerObject = outerObject.getJSONObject("JObjects");
    JSONArray jsonArray = innerObject.getJSONArray("JArray1");
    for (int i = 0, size = jsonArray.length(); i < size; i++)
    {
      JSONObject objectInArray = jsonArray.getJSONObject(i);

      // "...and get thier component and thier value."
      String[] elementNames = JSONObject.getNames(objectInArray);
      System.out.printf("%d ELEMENTS IN CURRENT OBJECT:\n", elementNames.length);
      for (String elementName : elementNames)
      {
        String value = objectInArray.getString(elementName);
        System.out.printf("name=%s, value=%s\n", elementName, value);
      }
      System.out.println();
    }
  }
}
/*
OUTPUT:
3 ELEMENTS IN CURRENT OBJECT:
name=A, value=a
name=B, value=b
name=C, value=c

5 ELEMENTS IN CURRENT OBJECT:

I tend to use Spring's Named JDBC Parameters so I can write a standard string like "select * from blah where colX=':someValue'"; I think that's pretty readable.

An alternative would be to supply the string in a separate .sql file and read the contents in using a utility method.

Oh, also worth having a look at Squill: https://squill.dev.java.net/docs/tutorial.html

    var p=document.getElementById('childId').parentNode;
    var c=document.getElementById('childId');
    p.removeChild(c);
    alert('Deleted');

p is parent node and c is child node
parentNode is a JavaScript variable which contains parent reference

Easy to understand

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{

    int num = 1234567;
    int den = 3;
    div_t r = div(num,den); // div() is a standard C function.
    printf("%d\n", r.quot);

    return 0;
}

use zzz instead of TZD

Example:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

Response:

2011-08-09T11:50:00:02+02:00

Best way is to find using log, it works always

int len = ceil(log10(num))+1;

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).

Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.

In your onCreate:

 yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
 yourSeekBar.setOnSeekBarChangeListener(new yourListener());

Your listener:

private class yourListener implements SeekBar.OnSeekBarChangeListener {

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
                            // Log the progress
            Log.d("DEBUG", "Progress is: "+progress);
                            //set textView's text
            yourTextView.setText(""+progress);
        }

        public void onStartTrackingTouch(SeekBar seekBar) {}

        public void onStopTrackingTouch(SeekBar seekBar) {}

    }

Please share some code and the Log results for furter help.

The fundamental difference in most programming languages is that unless the unexpected happens a for loop will always repeat n times or until a break statement, (which may be conditional), is met then finish with a while loop it may repeat 0 times, 1, more or even forever, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while loop, (or repeat until), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).

It is worth noting that in Python a for or while statement can have break, continue and else statements where:

• break - terminates the loop
• continue - moves on to the next time around the loop without executing following code this time around
• else - is executed if the loop completed without any break statements being executed.

N.B. In the now unsupported Python 2 range produced a list of integers but you could use xrange to use an iterator. In Python 3 range returns an iterator.

So the answer to your question is 'it all depends on what you are trying to do'!

You can create a base class in your application that inherits from System.Web.UI.Page. Let all your pages inherit from the newly created base class. Add a property or a variable to your base class with propected access modifier, so that it will be accessed from all your pages in the application.

PROBLEM:

I had a problem with ConstraintLayout and ScrollView when i wanted to include it in another layout.

DECISION:

The solution to my problem was to use dataBinding.

dataBinding (layout)

-background white -alpha remove -alpha off

Example:

convert image.png -background white -alpha remove -alpha off white.png

Feel free to replace white with any other color you want. Imagemagick documentation says this about the -alpha remove operation:

This operation is simple and fast, and does the job without needing any extra memory use, or other side effects that may be associated with alternative transparency removal techniques. It is thus the preferred way of removing image transparency.

Your example creates multiple key: value pairs if using fromkeys. If you don't want this, you can use one key and create an alias for the key. For example if you are using a register map, your key can be the register address and the alias can be register name. That way you can perform read/write operations on the correct register.

>>> mydict = {}
>>> mydict[(1,2)] = [30, 20]
>>> alias1 = (1,2)
>>> print mydict[alias1]
[30, 20]
>>> mydict[(1,3)] = [30, 30]
>>> print mydict
{(1, 2): [30, 20], (1, 3): [30, 30]}
>>> alias1 in mydict
True

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

I would use SharedSizeGroup

<Grid>
    <Grid.ColumnDefinition>
        <ColumnDefinition SharedSizeGroup="col1"></ColumnDefinition>  
        <ColumnDefinition SharedSizeGroup="col2"></ColumnDefinition>
    </Grid.ColumnDefinition>
    <TextBox Background="Azure" Text="Hello" Grid.Column="1" MaxWidth="200" />
</Grid>

My answer won't probably be useful to the writer of this question (I am 8 months late so not the right timing I guess) but I think it will probably be useful for many other developers that might come across this answer.

Today, I just released (in the name of my company) an HTML to POJO complete framework that you can use to map HTML to any POJO class with simply some annotations. The library itself is quite handy and features many other things all the while being very pluggable. You can have a look to it right here : https://github.com/whimtrip/jwht-htmltopojo

How to use : Basics

Imagine we need to parse the following html page :

<html>
    <head>
        <title>A Simple HTML Document</title>
    </head>
    <body>
        <div class="restaurant">
            <h1>A la bonne Franquette</h1>
            <p>French cuisine restaurant for gourmet of fellow french people</p>
            <div class="location">
                <p>in <span>London</span></p>
            </div>
            <p>Restaurant n*18,190. Ranked 113 out of 1,550 restaurants</p>  
            <div class="meals">
                <div class="meal">
                    <p>Veal Cutlet</p>
                    <p rating-color="green">4.5/5 stars</p>
                    <p>Chef Mr. Frenchie</p>
                </div>

                <div class="meal">
                    <p>Ratatouille</p>
                    <p rating-color="orange">3.6/5 stars</p>
                    <p>Chef Mr. Frenchie and Mme. French-Cuisine</p>
                </div>

            </div> 
        </div>    
    </body>
</html>

Let's create the POJOs we want to map it to :

public class Restaurant {

    @Selector( value = "div.restaurant > h1")
    private String name;

    @Selector( value = "div.restaurant > p:nth-child(2)")
    private String description;

    @Selector( value = "div.restaurant > div:nth-child(3) > p > span")    
    private String location;    

    @Selector( 
        value = "div.restaurant > p:nth-child(4)"
        format = "^Restaurant n\*([0-9,]+). Ranked ([0-9,]+) out of ([0-9,]+) restaurants$",
        indexForRegexPattern = 1,
        useDeserializer = true,
        deserializer = ReplacerDeserializer.class,
        preConvert = true,
        postConvert = false
    )
    // so that the number becomes a valid number as they are shown in this format : 18,190
    @ReplaceWith(value = ",", with = "")
    private Long id;

    @Selector( 
        value = "div.restaurant > p:nth-child(4)"
        format = "^Restaurant n\*([0-9,]+). Ranked ([0-9,]+) out of ([0-9,]+) restaurants$",
        // This time, we want the second regex group and not the first one anymore
        indexForRegexPattern = 2,
        useDeserializer = true,
        deserializer = ReplacerDeserializer.class,
        preConvert = true,
        postConvert = false
    )
    // so that the number becomes a valid number as they are shown in this format : 18,190
    @ReplaceWith(value = ",", with = "")
    private Integer rank;

    @Selector(value = ".meal")    
    private List<Meal> meals;

    // getters and setters

}

And now the Meal class as well :

public class Meal {

    @Selector(value = "p:nth-child(1)")
    private String name;

    @Selector(
        value = "p:nth-child(2)",
        format = "^([0-9.]+)\/5 stars$",
        indexForRegexPattern = 1
    )
    private Float stars;

    @Selector(
        value = "p:nth-child(2)",
        // rating-color custom attribute can be used as well
        attr = "rating-color"
    )
    private String ratingColor;

    @Selector(
        value = "p:nth-child(3)"
    )
    private String chefs;

    // getters and setters.
}

We provided some more explanations on the above code on our github page.

For the moment, let's see how to scrap this.

private static final String MY_HTML_FILE = "my-html-file.html";

public static void main(String[] args) {


    HtmlToPojoEngine htmlToPojoEngine = HtmlToPojoEngine.create();

    HtmlAdapter<Restaurant> adapter = htmlToPojoEngine.adapter(Restaurant.class);

    // If they were several restaurants in the same page, 
    // you would need to create a parent POJO containing
    // a list of Restaurants as shown with the meals here
    Restaurant restaurant = adapter.fromHtml(getHtmlBody());

    // That's it, do some magic now!

}


private static String getHtmlBody() throws IOException {
    byte[] encoded = Files.readAllBytes(Paths.get(MY_HTML_FILE));
    return new String(encoded, Charset.forName("UTF-8"));

}

Hope this will help someone out there!

A double quote character (") can be escaped as ", but here's the rest of the story...

Double quote character must be escaped in this context:

• In XML attributes delimited by double quotes:

  <EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
  

Double quote character need not be escaped in most contexts:

• In XML textual content:

  <NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
  

• In XML attributes delimited by single quotes ('):

  <NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
  

  Similarly, (') require no escaping if (") are used for the attribute value delimiters:

  <NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

the first way is better, the second way cost more time on creating a new array and converting to a list

Because the file you source ends lines with carriage returns, the contents of $testVar are likely to look like this:

$ printf '%q\n' "$testVar"
$'value123\r'

(The first line's $ is the shell prompt; the second line's $ is from the %q formatting string, indicating $'' quoting.)

To get rid of the carriage return, you can use shell parameter expansion and ANSI-C quoting (requires Bash):

testVar=${testVar//$'\r'}

Which should result in

$ printf '%q\n' "$testVar"
value123

No.

But if you're looking to treat your person1 object as if it were a Person, you can call methods on Person's prototype on person1 with call:

Person.prototype.getFullNamePublic = function(){
    return this.lastName + ' ' + this.firstName;
}
Person.prototype.getFullNamePublic.call(person1);

Though this obviously won't work for privileged methods created inside of the Person constructor—like your getFullName method.

Passable for getting multiple values with scanf()

int r,m,v,i,e,k;

scanf("%d%d%d%d%d%d",&r,&m,&v,&i,&e,&k);

You can use y.count().

It will return the integer value of the number of times a sub string appears in a string.

For example:

string.count("bah") >> 0
string.count("Hello") >> 1

In Eclipse Folder there is eclipse.ini file. Increase size -Xms512m -Xmx1024m

Sometimes you may want to get just the quantity of the months between two dates totally ignoring the day part. So for instance, if you had two dates- 2013/06/21 and 2013/10/18- and you only cared about the 2013/06 and 2013/10 parts, here are the scenarios and possible solutions:

var date1=new Date(2013,5,21);//Remember, months are 0 based in JS
var date2=new Date(2013,9,18);
var year1=date1.getFullYear();
var year2=date2.getFullYear();
var month1=date1.getMonth();
var month2=date2.getMonth();
if(month1===0){ //Have to take into account
  month1++;
  month2++;
}
var numberOfMonths; 

1.If you want just the number of the months between the two dates excluding both month1 and month2

numberOfMonths = (year2 - year1) * 12 + (month2 - month1) - 1;

2.If you want to include either of the months

numberOfMonths = (year2 - year1) * 12 + (month2 - month1);

3.If you want to include both of the months

numberOfMonths = (year2 - year1) * 12 + (month2 - month1) + 1;

If you need to organize data in columns of 1 / 2 / 4 depending of the viewport size then push and pull may be no option at all. No matter how you order your items in the first place, one of the sizes may give you a wrong order.

A solution in this case is to use nested rows and cols without any push or pull classes.

Example

In XS you want...

A
B
C
D
E
F
G
H

In SM you want...

A   E
B   F
C   G
D   H

In MD and above you want...

A   C   E   G
B   D   F   H

Solution

Use nested two-column child elements in a surrounding two-column parent element:

Here is a working snippet:

<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript" ></script>_x000D_
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"> _x000D_
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>_x000D_
_x000D_
<div class="row">_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>A</p><p>B</p></div>_x000D_
      <div class="col-md-6"><p>C</p><p>D</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>E</p><p>F</p></div>_x000D_
      <div class="col-md-6"><p>G</p><p>H</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Another beauty of this solution is, that the items appear in the code in their natural order (A, B, C, ... H) and don't have to be shuffled, which is nice for CMS generation.

function deepclone(obj) {
    let newObj = {};

    if (typeof obj === 'object') {
        for (let key in obj) {
            let property = obj[key],
                type = typeof property;
            switch (type) {
                case 'object':
                    if( Object.prototype.toString.call( property ) === '[object Array]' ) {
                        newObj[key] = [];
                        for (let item of property) {
                            newObj[key].push(this.deepclone(item))
                        }
                    } else {
                        newObj[key] = deepclone(property);
                    }
                    break;
                default:
                    newObj[key] = property;
                    break;

            }
        }
        return newObj
    } else {
        return obj;
    }
}

The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:

a) The IP/domain or port is incorrect

b) The IP/domain or port (i.e service) is down

c) The IP/domain is taking longer than your default timeout to respond

d) You have a firewall that is blocking requests or responses on whatever port you are using

e) You have a firewall that is blocking requests to that particular host

f) Your internet access is down

g) Your live-server is down i.e in case of "rest-API call".

Note that firewalls and port or IP blocking may be in place by your ISP

The Hash Password Support and Token Assertion Parameters in Metro 1.2 explains very nicely what a UsernameToken with Digest Password looks like:

Digest Password Support

The WSS 1.1 Username Token Profile allows digest passwords to be sent in a wsse:UsernameToken of a SOAP message. Two more optional elements are included in the wsse:UsernameToken in this case: wsse:Nonce and wsse:Created. A nonce is a random value that the sender creates to include in each UsernameToken that it sends. A creation time is added to combine nonces to a "freshness" time period. The Password Digest in this case is calculated as:

Password_Digest = Base64 ( SHA-1 ( nonce + created + password ) )

This is how a UsernameToken with Digest Password looks like:

<wsse:UsernameToken wsu:Id="uuid_faf0159a-6b13-4139-a6da-cb7b4100c10c">
   <wsse:Username>Alice</wsse:Username>
   <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">6S3P2EWNP3lQf+9VC3emNoT57oQ=</wsse:Password>
   <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">YF6j8V/CAqi+1nRsGLRbuZhi</wsse:Nonce>
   <wsu:Created>2008-04-28T10:02:11Z</wsu:Created>
</wsse:UsernameToken>

+"\n" + can be added in print command to display the code block after it in next line

E.g. System.out.println ("a" + "\n" + "b") outputs a in first line and b in second line.

HTML4 specification states that:

Inline elements may contain only data and other inline elements

Span is an inline element, therefore having span inside span is valid. There's a related question: Can <span> tags have any type of tags inside them? which makes it completely clear.

HTML5 specification (including the most current draft of HTML 5.3 dated November 16, 2017) changes terminology, but it's still perfectly valid to place span inside another span.

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

This one is working for me.

If we need to move from one component to another service then we have to define that service into app.module providers array.

The documentation says that these two methods are equivalent:

StreamReader.Close: This implementation of Close calls the Dispose method passing a true value.

StreamWriter.Close: This implementation of Close calls the Dispose method passing a true value.

Stream.Close: This method calls Dispose, specifying true to release all resources.

So, both of these are equally valid:

/* Option 1, implicitly calling Dispose */
using (StreamWriter writer = new StreamWriter(filename)) { 
   // do something
} 

/* Option 2, explicitly calling Close */
StreamWriter writer = new StreamWriter(filename)
try {
    // do something
}
finally {
    writer.Close();
}

Personally, I would stick with the first option, since it contains less "noise".

Assuming you are writing a bootloader or other application that has access to the BIOS, here is a rough sketch of what you can do:

• Isolate the first digit of the hex byte
• If it is greater than 9 (i.e. 0x0A to 0x0F), subtract 10 from it (scaling it down to 0 to 5), and add 'A' (0x41).
• If it is less than or equal to 9 (i.e. 0x00 to 0x09), add '0' to it.
• Repeat this with the next hex digit.

Here is my implementation of this:

; Prints AL in hex.
printhexb:
    push ax
    shr al, 0x04
    call print_nibble
    pop ax
    and al, 0x0F
    call print_nibble
    ret
print_nibble:
    cmp al, 0x09
    jg .letter
    add al, 0x30
    mov ah, 0x0E
    int 0x10
    ret
.letter:
    add al, 0x37
    mov ah, 0x0E
    int 0x10
    ret   

List is an interface, and you can not initialize an interface. Instantiate an implementing class instead.

Like:

List<String> abc = new ArrayList<String>();
List<String> xyz = new LinkedList<String>();

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

If you want to use free version of font awesome - bootstrap, use this :

npm install --save @fortawesome/fontawesome-free

If you are building angular project, you also need to add these imports in your angular.json :

"styles": [
          "src/styles.css",
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "node_modules/@fortawesome/fontawesome-free/css/fontawesome.min.css"
        ],
        "scripts": [
          "node_modules/jquery/dist/jquery.min.js",
          "node_modules/bootstrap/dist/js/bootstrap.min.js",
          "node_modules/popper.js/dist/umd/popper.min.js",
          "node_modules/@fortawesome/fontawesome-free/js/all.js"
        ]

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

You can also use nvl(Column,0)

Here's a list : http://delphi.about.com/od/devutilities/a/decompiling_3.htm (and this page mentions some more : http://www.program-transformation.org/Transform/DelphiDecompilers )

I've used DeDe on occasion, but it's not really all that powerfull, and it's not up-to-date with current Delphi versions (latest version it supports is Delphi 7 I believe)

In my case I had to enable another extension, namely php_mbstring.dll in the php.ini file before it could work. It's listed under extension=php_mbstring.dll. Find it in the php.ini file and remove the semi-colon (;) in front of it and save the file.

After this run install composer again in the root directory of your Laravel applcication and is should work.

On Fedora, this works:

sudo yum install -y python-pip
sudo yum install -y lapack lapack-devel blas blas-devel 
sudo yum install -y blas-static lapack-static
sudo pip install numpy
sudo pip install scipy

If you get any public key errors while downloading, add --nogpgcheck as parameter to yum, for example: yum --nogpgcheck install blas-devel

On Fedora 23 onwards, use dnf instead of yum.

There's a difference between the raw queries and standard selects (between the DB::raw and DB::select methods).

You can do what you want using a DB::select and simply dropping in the ? placeholder much like you do with prepared statements (it's actually what it's doing).

A small example:

$results = DB::select('SELECT * FROM user WHERE username=?', ['jason']);

The second parameter is an array of values that will be used to replace the placeholders in the query from left to right.

in your <head>

<meta id="viewport"
      name="viewport"
      content="width=1024, height=768, initial-scale=0, minimum-scale=0.25" />

somewhere in your javascript

document.getElementById("viewport").setAttribute("content",
      "initial-scale=0.5; maximum-scale=1.0; user-scalable=0;");

... but good luck with tweaking it for your device, fiddling for hours... and i'm still not there!

This may not completely answer your question but you could also try using the Elevate Command Powertoy in order to run the script with elevated UAC privileges.

http://technet.microsoft.com/en-us/magazine/2008.06.elevation.aspx

I think if you use it it would look like 'elevate python yourscript.py'

Here You Go with Fiddle:

FIDDLE

HTML:

<ol>
        <li>List 1          
            <ol>
                <li>Sub-Chapter</li>
                <li>Sub-Chapter</li>
            </ol>
        </li>
        <li>List 2
            <ol>
                <li>Sub-Chapter</li>
                <li>Sub-Chapter</li>
            </ol>
        </li>
        <li>List 3</li>
</ol>

CSS:

ol {counter-reset:item;}
ol li {display:block;}
li:before {content:counters(item, ".");counter-increment:item;left:-7px;position:relative;font-weight:bold;}

If the script creates any variables or functions in the global space you can check for their existance:

External JS (in global scope) --

var myCustomFlag = true;

And to check if this has run:

if (typeof window.myCustomFlag == 'undefined') {
    //the flag was not found, so the code has not run
    $.getScript('<external JS>');
}

Update

You can check for the existence of the <script> tag in question by selecting all of the <script> elements and checking their src attributes:

//get the number of `<script>` elements that have the correct `src` attribute
var len = $('script').filter(function () {
    return ($(this).attr('src') == '<external JS>');
}).length;

//if there are no scripts that match, the load it
if (len === 0) {
    $.getScript('<external JS>');
}

Or you can just bake this .filter() functionality right into the selector:

var len = $('script[src="<external JS>"]').length;

There's also a really useful discussion about converting the array in place, In-place type conversion of a NumPy array. If you're concerned about copying your array (which is whatastype() does) definitely check out the link.

Simply move the declaration outside of the if block.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store2_logo.gif";
    }
}

<a href="@Url.RouteUrl("HomePage")" class="logo"><img  alt="" src="@imgsrc"></a>

You could make it a bit cleaner.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="/content/images/uploaded/store2_logo.gif";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    }
}

The <appSettings> tag in web.config supports a file attribute that will load an external config with it's own set of key/values. These will override any settings you have in your web.config or add to them.

We take advantage of this by modifying our web.config at install time with a file attribute that matches the environment the site is being installed to. We do this with a switch on our installer.

eg;

<appSettings file=".\EnvironmentSpecificConfigurations\dev.config">

<appSettings file=".\EnvironmentSpecificConfigurations\qa.config">

<appSettings file=".\EnvironmentSpecificConfigurations\production.config">

Note:

• Changes to the .config specified by the attribute won't trigger a restart of the asp.net worker process

I noticed that Pandas for example will return 'nan' for blank values. Since it's not a string you need to convert it to one in order to match it. For example:

ulist = df.column1.unique() #create a list from a column with Pandas which 
for loc in ulist:
    loc = str(loc)   #here 'nan' is converted to a string to compare with if
    if loc != 'nan':
        print(loc)

Another solution:

If you have a static subclass in a non-static outer class, you can access the resources from within the subclass via static variables in the outer class, which you initialise on creation of the outer class. Like

public class Outerclass {

    static String resource1

    public onCreate() {
        resource1 = getString(R.string.text);
    }

    public static class Innerclass {

        public StringGetter (int num) {
            return resource1; 
        }
    }
}

I used it for the getPageTitle(int position) Function of the static FragmentPagerAdapter within my FragmentActivity which is useful because of I8N.

Using Moshi:

When building your Retrofit Service add .asLenient() to your MoshiConverterFactory. You don't need a ScalarsConverter. It should look something like this:

return Retrofit.Builder()
                .client(okHttpClient)
                .baseUrl(ENDPOINT)
                .addConverterFactory(MoshiConverterFactory.create().asLenient())
                .build()
                .create(UserService::class.java)

var currentDate = moment('2015-10-30');
var futureMonth = moment(currentDate).add(1, 'M');
var futureMonthEnd = moment(futureMonth).endOf('month');

if(currentDate.date() != futureMonth.date() && futureMonth.isSame(futureMonthEnd.format('YYYY-MM-DD'))) {
    futureMonth = futureMonth.add(1, 'd');
}

console.log(currentDate);
console.log(futureMonth);

DEMO

EDIT

moment.addRealMonth = function addRealMonth(d) {
  var fm = moment(d).add(1, 'M');
  var fmEnd = moment(fm).endOf('month');
  return d.date() != fm.date() && fm.isSame(fmEnd.format('YYYY-MM-DD')) ? fm.add(1, 'd') : fm;  
}

var nextMonth = moment.addRealMonth(moment());

DEMO

I know this is late but it might be of some use:

echo "<pre>";
print_r($array);
echo "</pre>";

It's worth noting that multiple field indexes can drastically improve your query performance. So in the above example we assume ProductID is the only field to lookup but were the query to say ProductID = 1 AND Category = 7 then a multiple column index helps. This is achieved with the following:

ALTER TABLE `table` ADD INDEX `index_name` (`col1`,`col2`)

Additionally the index should match the order of the query fields. In my extended example the index should be (ProductID,Category) not the other way around.

This has happened to me after I "updated" into 5.0 SDK and wanted to create a new application with support library

In both Projects (project.properties file) in the one you want to use support library and the support library itself it has to be set the same target

e.g. for my case it worked

1. In project android-support-v7-appcompat Change project.properties into target=android-21
2. Cleanandroid-support-v7-appcompat In my project (where I desire support library)
3. In my project, Change project.properties into target=android-21 and android.library.reference.1=../android-support-v7-appcompat (or add support library in project properties)
4. Clean the project

In my case, I was running tests through MSTest and found out that I was deploying both a 32-bit and 64-bit DLL to the test directory. The program was favoring the 64-bit DLL and causing it to fail.

TL;DR Make sure you only deploy 32-bit DLLs to tests.

You can try @Rule annotation. Here is the example from the docs:

public static class UsesExternalResource {
    Server myServer = new Server();

    @Rule public ExternalResource resource = new ExternalResource() {
        @Override
        protected void before() throws Throwable {
            myServer.connect();
        };

        @Override
        protected void after() {
            myServer.disconnect();
        };
    };

    @Test public void testFoo() {
        new Client().run(myServer);
    }
}

You just need to create FileResource class extending ExternalResource.

Let's get you started. Do you have any knowledge in Oracle?

First you need to understand what a SCHEMA is. A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema. Schema objects can be created and manipulated with SQL.

1. CREATE USER acoder; -- whenever you create a new user in Oracle, a schema with the same name as the username is created where all his objects are stored.
2. GRANT CREATE SESSION TO acoder; -- Failure to do this you cannot do anything.

To access another user's schema, you need to be granted privileges on specific object on that schema or optionally have SYSDBA role assigned.

That should get you started.

Overall I don't see anything that would break in your code.

Two suggestions:

The way you are combining Buffer objects is a suboptimal because it has to copy all the pre-existing data on every 'data' event. It would be better to put the chunks in an array and concat them all at the end.

var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
  var buf = Buffer.concat(bufs);
}

For performance, I would look into if the S3 library you are using supports streams. Ideally you wouldn't need to create one large buffer at all, and instead just pass the stdout stream directly to the S3 library.

As for the second part of your question, that isn't possible. When a function is called, it is allocated its own private context, and everything defined inside of that will only be accessible from other items defined inside that function.

Update

Dumping the file to the filesystem would probably mean less memory usage per request, but file IO can be pretty slow so it might not be worth it. I'd say that you shouldn't optimize too much until you can profile and stress-test this function. If the garbage collector is doing its job you may be overoptimizing.

With all that said, there are better ways anyway, so don't use files. Since all you want is the length, you can calculate that without needing to append all of the buffers together, so then you don't need to allocate a new Buffer at all.

var pause_stream = require('pause-stream');

// Your other code.

var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
  var contentLength = bufs.reduce(function(sum, buf){
    return sum + buf.length;
  }, 0);

  // Create a stream that will emit your chunks when resumed.
  var stream = pause_stream();
  stream.pause();
  while (bufs.length) stream.write(bufs.shift());
  stream.end();

  var headers = {
      'Content-Length': contentLength,
      // ...
  };

  s3.putStream(stream, ....);

I encountered what appeared to be this error. I was running on windows and found my administrator windows user did not have administrator privileges to database.

1. Shut down SQL Server from ‘Services’

2. Open cmd window (as administrator) and run single-user mode as local admin with this command (the version of MSSQL may differ):

"C:\Program Files\Microsoft SQL Server\MSSQL14.SQLEXPRESS\MSSQL\Binn\sqlservr.exe" -m -s SQLEXPRESS

3. Open another cmd window (as administrator)
4. Open sqlcmd on that terminal with:

sqlcmd -S .\SQLEXPRESS

5. Now add the sysadmin role to your user:

sp_addsrvrolemember 'domain\user', 'sysadmin'
GO

6. Re-enable SQL Server from ‘Services’

$rows = array();
while($r = mysql_fetch_assoc($result)) {
    $r["id"] = intval($r["id"]); 
    $rows[] = $r;
}
print json_encode($rows);  

@AnandaMahto has addressed why you're getting these results and provided the clearest way to get what you want. But another option would be to use identical instead of ==.

test$ID <- ifelse(is.na(test$time) | sapply(as.character(test$type), identical, "A"), NA, "1")

Or use isTRUE:

test$ID <- ifelse(is.na(test$time) | Vectorize(isTRUE)(test$type == "A"), NA, "1")

Since Java 1.7 you can use Objects.equals:

java.util.Objects.equals(oneInteger, anotherInteger);

Returns true if the arguments are equal to each other and false otherwise. Consequently, if both arguments are null, true is returned and if exactly one argument is null, false is returned. Otherwise, equality is determined by using the equals method of the first argument.

If you're trying to copy the array:

array2 = array[:]

For parseInt to work, your string should have only numerical data. Something like this:

 str1 = "123.00";
 str2 = "50.00";
 total = parseInt(str1)+parseInt(str2);
 alert(total);

Can you split the string before you start processing them for a total?

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

You should use the OpenFileDialog class like this

Dim fd As OpenFileDialog = New OpenFileDialog() 
Dim strFileName As String

fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True

If fd.ShowDialog() = DialogResult.OK Then
   strFileName = fd.FileName
End If

Then you can use the File class.

Running

npm run scss
npm run start 

in that order in terminal solved the issue for me.

In my case because I assigned the post data to the header, this is how I get it:

protected void Page_Load(object sender, EventArgs e){
    ...
    postValue = Request.Headers["Key"];

This is how I attached the value and key to the POST:

var request = new NSMutableUrlRequest(url){
    HttpMethod = "POST", 
    Headers = NSDictionary.FromObjectAndKey(FromObject(value), FromObject("key"))
};
webView.LoadRequest(request);

In Tomcat 7 with these changes, i'm able to access myAPP at / and ROOT at /ROOT

<Context path="" docBase="myAPP"/>
<Context path="ROOT" docBase="ROOT"/>

Add above to the <Host> section in server.xml

I'm a few years late, but why not this?

This is easy to do with a terms panel:

If you want to select the count of distinct IP that are in your logs, you should specify in the field clientip, you should put a big enough number in length (otherwise, it will join different IP under the same group) and specify in the style table. After adding the panel, you will have a table with IP, and the count of that IP:

The svnbook has a section on how Subversion allows you to revert the changes from a particular revision without affecting the changes that occured in subsequent revisions:

http://svnbook.red-bean.com/en/1.4/svn.branchmerge.commonuses.html#svn.branchmerge.commonuses.undo

I don't use Eclipse much, but in TortoiseSVN you can do this from the from the log dialogue; simply right-click on the revision you want to revert and select "Revert changes from this revision".

In the case that the files for which you want to revert "bad changes" had "good changes" in subsequent revisions, then the process is the same. The changes from the "bad" revision will be reverted leaving the changes from "good" revisions untouched, however you might get conflicts.

All you need to do is to put arp into diferrent group.

Default:

-rwxr-xr-x 1 root root 48K 2008-11-11 18:11 /usr/sbin/arp*

With command:

sudo chown root:www-data /usr/sbin/arp

you will get:

-rwxr-xr-x 1 root www-data 48K 2008-11-11 18:11 /usr/sbin/arp*

And because apache is a daemon running under the user www-data, it's now able to execute this command.

So if you now use a PHP script, e.g.:

<?php
$mac = system('arp -an');
echo $mac;
?>

you will get the output of linux arp -an command.

steps :

1. run your xampp control panel
2. click the button saying config
3. select apache( httpd.conf )
4. find document root

replace

DocumentRoot "C:/xampp/htdocs"
<Directory "C:/xampp/htdocs">

Those 2 lines

| C:/xampp/htdocs == current location for root |

|change C:/xampp/htdocs with any location you want|

5. save it

DONE: start apache and go to the localhost see in action [ watch video click here ]

This can be done pretty easily. All I did was move the existing directory, not under version control, to a temporary directory. Then I checked out the SVN version to my correct directory name, copied the files from the temporary directory into the SVN directory, and reverted the files in the SVN directory. If that does not make sense there is an example below:

/usr/local/www

mv www temp_www
svn co http://www.yourrepo.com/therepo www
cp -pR ./temp_www/* ./www
svn revert -R ./www/*
svn update

I hope this helps and am not sure why just a simple SVN update did not change the files back?

This is an old post but still a problem within the Chrome dev tools. I find the best way to check mobile source locally is to open the site locally in Xcode's iOS Simulator. Then from there you open the Safari browser and enable dev tools, if you have not already done this (go to preferences -> advanced -> show develop menu in menu bar). Now you will see the develop option in the main menu and can go to develop -> iOS Simulator -> and the page you have open in Xcode's iOS Simulator will be there. Once you click on it, it will open the web inspector and you can edit as you would normally in the browser dev tools.

I'm afraid this solution will only work on a Mac though as it uses Xcode.

Input the following formula in C1:

=IF(ISNA(A1),B1,A1*B1)

Screenshots:

When #N/A:

When not #N/A:

The code looks strange because the printf are not in any function blocks.

If you wants to center the dropdown, this is the solution.

<ul class="dropdown-menu" style="right:auto; left: auto;">

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Also try:

ul {
  list-style-position: inside;

A back link is a link that moves the browser backwards one page, as if the user had clicked the Back button available in most browsers. Back links use JavaScript. It moves the browser back one page if your browser supports JavaScript (which it does) and if it supports the window.history object, which is necessary for back links.

Simple ways are

<a href="#" onClick="history.go(-1)">Go Back</a>

OR:

function goBack() {_x000D_
  window.history.back()_x000D_
}

<a href="#" onclick="goBack()" />Go Back</a>

Generally speaking a back link isn't necessary… the Back button usually suffices quite nicely, and usually you can also simply link to the previous page in your site. However, sometimes you might want to provide a link back to one of several "previous" pages, and that's where a back link comes in handy. So I refer you below tutorial if you want to do in more advanced way:

http://www.htmlcodetutorial.com/linking/linking_famsupp_108.html

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

Is so simple,only add your java path for example:

C:\Program Files\Java\jdk1.8.0_121\bin

in PATH system variable

Try using rowMeans:

z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)

  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

You could use super(ChildClass, self).__init__()

class BaseClass(object):
    def __init__(self, *args, **kwargs):
        pass

class ChildClass(BaseClass):
    def __init__(self, *args, **kwargs):
        super(ChildClass, self).__init__(*args, **kwargs)

Your indentation is incorrect, here's the modified code:

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):
    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super(ElectricCar, self).__init__(model, color, mpg)

car = ElectricCar('battery', 'ford', 'golden', 10)
print car.__dict__

Here's the output:

{'color': 'golden', 'mpg': 10, 'model': 'ford', 'battery_type': 'battery'}

Just learning this myself. I will answer the second question:

2. How to use these files? Currently I am using webpack-dev-server to run the application.

Instead of using webpack-dev-server, you can just run an "express". use npm install "express" and create a server.js in the project's root dir, something like this:

var path = require("path");
var express = require("express");

var DIST_DIR = path.join(__dirname, "build");
var PORT = 3000;
var app = express();

//Serving the files on the dist folder
app.use(express.static(DIST_DIR));

//Send index.html when the user access the web
app.get("*", function (req, res) {
  res.sendFile(path.join(DIST_DIR, "index.html"));
});

app.listen(PORT);

Then, in the package.json, add a script:

"start": "node server.js"

Finally, run the app: npm run start to start the server

A detailed example can be seen at: https://alejandronapoles.com/2016/03/12/the-simplest-webpack-and-express-setup/ (the example code is not compatible with the latest packages, but it will work with small tweaks)

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

All you need is width:100% somewhere that applies to the tag as shown by the various answers here.

Using col-xs-12:

<!-- adds float:left, which is usually not a problem -->
<img class='img-responsive col-xs-12' />

Or inline CSS:

<img class='img-responsive' style='width:100%;' />

Or, in your own CSS file, add an additional definition for .img-responsive

.img-responsive { 
    width:100%;
}

THE ROOT OF THE PROBLEM

This is a known FF bug that <fieldset> does not respect overflow rules:

https://bugzilla.mozilla.org/show_bug.cgi?id=261037

A CSS "FIX" to fix the FireFox bug would be to make the <fieldset> display:table-column. However, doing so, according to the following link, will cause the display of the fieldset to fail in Opera:

https://github.com/TryGhost/Ghost/issues/789

So, just set your tag to 100% width as described in one of the solutions above.

1. I agree with yossi's example, stretch the image to fit the div but in a slightly different way (without background-image as this is a little inflexible in css 2.1). Show full image:

   <div id="yourdiv">
       <img id="theimage" src="image.jpg" alt="" />
   </div>
   
   #yourdiv img {
       width:100%;
     /*height will be automatic to remain aspect ratio*/
   }
   

2. Show part of the image using background-position:

   #yourdiv 
   {
       background-image: url(image.jpg);
       background-repeat: no-repeat;
       background-position: 10px 25px;
   }
   

3. Same as the first part of (1) the image will scale to the div so bigger or smaller will both work

4. Same as yossi's.

BhupeshC and murat , this is what I was looking for. However @SQL varchar(4000) wasn't big enough. So, small change

DECLARE @cmd varchar(4000)

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 

select 'ALTER TABLE ['+s.name+'].['+t.name+'] DROP CONSTRAINT [' + RTRIM(f.name) +'];' FROM sys.Tables t INNER JOIN sys.foreign_keys f ON f.parent_object_id = t.object_id INNER JOIN sys.schemas s ON s.schema_id = f.schema_id

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @cmd
WHILE @@FETCH_STATUS = 0
BEGIN
    -- EXEC (@cmd)
    PRINT @cmd
    FETCH NEXT FROM MY_CURSOR INTO @cmd
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

GO

Let's illustrate what's happening here:

Python 3.1.2 (r312:79147, Sep 27 2010, 09:45:41) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Foo:
...     def __init__(self, x=[]):
...         x.append(1)
... 
>>> Foo.__init__.__defaults__
([],)
>>> f = Foo()
>>> Foo.__init__.__defaults__
([1],)
>>> f2 = Foo()
>>> Foo.__init__.__defaults__
([1, 1],)

You can see that the default arguments are stored in a tuple which is an attribute of the function in question. This actually has nothing to do with the class in question and goes for any function. In python 2, the attribute will be func.func_defaults.

As other posters have pointed out, you probably want to use None as a sentinel value and give each instance it's own list.

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.
