I think the easiest thing to do is just to reuse dirname() So you can call

os.path.dirname(os.path.dirname( __file__ ))

if you file is at /Users/hobbes3/Sites/mysite/templates/method.py

This will return "/Users/hobbes3/Sites/mysite"

If you want to remove the glow from buttons in Bootstrap (which is not necessarily bad UX in my opinion), you'll need the following code:

.btn:focus, .btn:active:focus, .btn.active:focus{
  outline-color: transparent;
  outline-style: none;
}

Use title attribute. It is a standard HTML attribute and is by default rendered in a tooltip by most desktop browsers.

Use this syntax:

obj[name]

Note that obj.x is the same as obj["x"] for all valid JS identifiers, but the latter form accepts all string as keys (not just valid identifiers).

obj["Hey, this is ... neat?"] = 42

About "can it be that 0 errors and IsValid == false": here's MVC source code from https://github.com/Microsoft/referencesource/blob/master/System.Web/ModelBinding/ModelStateDictionary.cs#L37-L41

public bool IsValid {
    get {
        return Values.All(modelState => modelState.Errors.Count == 0);
    }
}

Now, it looks like it can't be. Well, that's for ASP.NET MVC v1.

I think you're getting confused about what can hold what in JSON.Net.

• A JToken is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.
• A JProperty is a single JToken value paired with a name. It can only be added to a JObject, and its value cannot be another JProperty.
• A JObject is a collection of JProperties. It cannot hold any other kind of JToken directly.

In your code, you are attempting to add a JObject (the one containing the "banana" data) to a JProperty ("orange") which already has a value (a JObject containing {"colour":"orange","size":"large"}). As you saw, this will result in an error.

What you really want to do is add a JProperty called "banana" to the JObject which contains the other fruit JProperties. Here is the revised code:

JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));

Just add this to your view:

<?php header("Access-Control-Allow-Origin: *"); ?>

This should work for any table, instead of hard-coding the columns.

You can set up Maven's Surefire to run unit tests and integration tests separately. In the standard unit test phase you run everything that does not pattern match an integration test. You then create a second test phase that runs just the integration tests.

Here is an example:

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
        <excludes>
          <exclude>**/*IntegrationTest.java</exclude>
        </excludes>
      </configuration>
      <executions>
        <execution>
          <id>integration-test</id>
          <goals>
            <goal>test</goal>
          </goals>
          <phase>integration-test</phase>
          <configuration>
            <excludes>
              <exclude>none</exclude>
            </excludes>
            <includes>
              <include>**/*IntegrationTest.java</include>
            </includes>
          </configuration>
        </execution>
      </executions>

You can use this query. Work in all SQL Server editions. It's simple, and clear. But you need use 2 queries. You can use if you can't use MERGE

    BEGIN TRAN

    UPDATE table
    SET Id = @ID, Description = @Description
    WHERE Id = @Id

    INSERT INTO table(Id, Description)
    SELECT @Id, @Description
    WHERE NOT EXISTS (SELECT NULL FROM table WHERE Id = @Id)

    COMMIT TRAN

NOTE: Please explain answer negatives

Use this method to set margin in dp

private void setMargins (View view, int left, int top, int right, int bottom) {
    if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

        final float scale = getBaseContext().getResources().getDisplayMetrics().density;
        // convert the DP into pixel
        int l =  (int)(left * scale + 0.5f);
        int r =  (int)(right * scale + 0.5f);
        int t =  (int)(top * scale + 0.5f);
        int b =  (int)(bottom * scale + 0.5f);

        p.setMargins(l, t, r, b);
        view.requestLayout();
    }
}

call the method :

setMargins(linearLayout,5,0,5,0);

The problem with your code snippet is the way variables are expanded. Variable expansion is usually done when a statement is first read. In your case the whole FOR loop and its block is read and all variables, except the loop variables are expanded to their current value.

This means %c% in your echo %%i, %c% expanded instantly and so is actually used as echo %%i, 1 in each loop iteration.

So what you need is the delayed variable expansion. Find some good explanation about it here.

Variables that should be delay expanded are referenced with !VARIABLE! instead of %VARIABLE%. But you need to activate this feature with setlocal ENABLEDELAYEDEXPANSION and reset it with a matching endlocal.

Your modified code would look something like that:

set TEXT_T="myfile.txt"

set /a c=1

setlocal ENABLEDELAYEDEXPANSION

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
  set /a c=c+1

  echo %%i, !c!
)

endlocal

The traceback module and sys.exc_info are overkill for tracking down the source of an exception. That's all in the default traceback. So instead of calling exit(1) just re-raise:

try:
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
except AssertionError:
    print 'Houston, we have a problem.'
    raise

Which gives the following output that includes the offending statement and line number:

Houston, we have a problem.
Traceback (most recent call last):
  File "/tmp/poop.py", line 2, in <module>
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
AssertionError: Should've asked for pie

Similarly the logging module makes it easy to log a traceback for any exception (including those which are caught and never re-raised):

import logging

try:
    assert False == True 
except AssertionError:
    logging.error("Nothing is real but I can't quit...", exc_info=True)

For even more robustness:

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

and

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

if (frame_win) {
  frame_win.reset();
  ...
}
...

A simpler way to get the selected value from a ComboBox control is:

Private Sub myComboBox_Change()
  msgbox "You selected: " + myComboBox.SelText
End Sub

Other posters have already explained why the :focus pseudo class is insufficient, but finally there is a CSS-based standard solution.

CSS Selectors Level 4 defines a new pseudo class:

:focus-within

From MDN:

The :focus-within CSS pseudo-class matches any element that the :focus pseudo-class matches or that has a descendant that the :focus pseudo-class matches. (This includes descendants in shadow trees.)

So now with the :focus-within pseudo class - styling the outer div when the textarea gets clicked becomes trivial.

.box:focus-within {
    border: thin solid black;
}

.box {_x000D_
    width: 300px;_x000D_
    height: 300px;_x000D_
    border: 5px dashed red;_x000D_
}_x000D_
_x000D_
.box:focus-within {_x000D_
    border: 5px solid green;_x000D_
}

<p>The outer box border changes when the textarea gets focus.</p>_x000D_
<div class="box">_x000D_
    <textarea rows="10" cols="25"></textarea>_x000D_
</div>

Just in case if the problem is still there, You can refer to ansible inventory through ‘hostvars’, ‘group_names’, and ‘groups’ ansible variables.

Example:

To be able to get ip addresses of all servers within group "mygroup", use the below construction:

- debug: msg="{{ hostvars[item]['ansible_eth0']['ipv4']['address'] }}" 
  with_items:
     - "{{ groups['mygroup'] }}"

I quite often use ajaxpro along with jQuery. ajaxpro lets me call .NET functions from JavaScript and I use jQuery for the rest.

@swpd's answer improved

I use , as a leader key and ,a shortcut does the trick

Add this line if you prefer ,a shortcut

map <Leader>a :%y+<CR> 

I use Ctrl y shortcut to copy

vmap <C-y> y:call system("xclip -i -selection clipboard", getreg("\""))<CR>:call system("xclip -i", getreg("\""))<CR>

And ,v to paste

nmap <Leader>v :call setreg("\"",system("xclip -o -selection clipboard"))<CR>p

Before using this you have to install xclip

$ sudo apt-get install xclip

Edit: When you use :%y+, it can be only pasted to Vim vim Ctrl+Insert shortcut. And

map <C-a> :%y+<Esc>

is not conflicting any settings in my Vimrc.

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

If you are running code and want to take input via running your program in the terminal, the best thing to do is to run it in terminal directly by just right click and choose "Run Python File in Terminal".

Bcrypt is a one-way hashing algorithm, you can't decrypt hashes. Use password_verify to check whether a password matches the stored hash:

<?php
// See the password_hash() example to see where this came from.
$hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';

if (password_verify('rasmuslerdorf', $hash)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}

In your case, run the SQL query using only the username:

$sql_script = 'SELECT * FROM USERS WHERE username=?';

And do the password validation in PHP using a code that is similar to the example above.

The way you are constructing the query is very dangerous. If you don't parameterize the input properly, the code will be vulnerable to SQL injection attacks. See this Stack Overflow answer on how to prevent SQL injection.

In C++ the requirements imposed on default arguments with regard to their location in parameter list are as follows:

1. Default argument for a given parameter has to be specified no more than once. Specifying it more than once (even with the same default value) is illegal.

2. Parameters with default arguments have to form a contiguous group at the end of the parameter list.

Now, keeping that in mind, in C++ you are allowed to "grow" the set of parameters that have default arguments from one declaration of the function to the next, as long as the above requirements are continuously satisfied.

For example, you can declare a function with no default arguments

void foo(int a, int b);

In order to call that function after such declaration you'll have to specify both arguments explicitly.

Later (further down) in the same translation unit, you can re-declare it again, but this time with one default argument

void foo(int a, int b = 5);

and from this point on you can call it with just one explicit argument.

Further down you can re-declare it yet again adding one more default argument

void foo(int a = 1, int b);

and from this point on you can call it with no explicit arguments.

The full example might look as follows

void foo(int a, int b);

int main()
{
  foo(2, 3);

  void foo(int a, int b = 5); // redeclare
  foo(8); // OK, calls `foo(8, 5)`

  void foo(int a = 1, int b); // redeclare again
  foo(); // OK, calls `foo(1, 5)`
}

void foo(int a, int b)
{
  // ...
}

As for the code in your question, both variants are perfectly valid, but they mean different things. The first variant declares a default argument for the second parameter right away. The second variant initially declares your function with no default arguments and then adds one for the second parameter.

The net effect of both of your declarations (i.e. the way it is seen by the code that follows the second declaration) is exactly the same: the function has default argument for its second parameter. However, if you manage to squeeze some code between the first and the second declarations, these two variants will behave differently. In the second variant the function has no default arguments between the declarations, so you'll have to specify both arguments explicitly.

If you do not have the pandas and sqlalchemy libraries, import using pip

pip install pandas
pip install sqlalchemy

We can use pandas and sqlalchemy to directly insert into the database

import csv
import pandas as pd
from sqlalchemy import create_engine, types

engine = create_engine('mysql://root:*Enter password here*@localhost/*Enter Databse name here*') # enter your password and database names here

df = pd.read_csv("Excel_file_name.csv",sep=',',quotechar='\'',encoding='utf8') # Replace Excel_file_name with your excel sheet name
df.to_sql('Table_name',con=engine,index=False,if_exists='append') # Replace Table_name with your sql table name

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

One approach: if you can guarantee unrelated applications won't use the files in a conflicting manner, just create a pool of files of varying sizes in a specific directory, then create links to them when needed.

For example, have a pool of files called:

• /home/bigfiles/512M-A
• /home/bigfiles/512M-B
• /home/bigfiles/1024M-A
• /home/bigfiles/1024M-B

Then, if you have an application that needs a 1G file called /home/oracle/logfile, execute a "ln /home/bigfiles/1024M-A /home/oracle/logfile".

If it's on a separate filesystem, you will have to use a symbolic link.

The A/B/etc files can be used to ensure there's no conflicting use between unrelated applications.

The link operation is about as fast as you can get.

Those who prefer to use laravel helpers they can check if a request is ajax using laravel request() helper.

This can happen when your plot panel in RStudio is too small for the margins of the plot you are trying to create. Try making expanding it and then run your code again.

RStudio UI causes an error when the plot panel is too small to display the chart:

Simply expanding the plot panel fixes the bug and displays the chart:

You can reverse the logic. Instead of deleting an invalid row after it has been inserted, write an INSTEAD OF trigger to insert only if you verify the row is valid.

CREATE TRIGGER mytrigger ON sometable
INSTEAD OF INSERT
AS BEGIN
  DECLARE @isnum TINYINT;

  SELECT @isnum = ISNUMERIC(somefield) FROM inserted;

  IF (@isnum = 1)
    INSERT INTO sometable SELECT * FROM inserted;
  ELSE
    RAISERROR('somefield must be numeric', 16, 1)
      WITH SETERROR;
END

If your application doesn't want to handle errors (as Joel says is the case in his app), then don't RAISERROR. Just make the trigger silently not do an insert that isn't valid.

I ran this on SQL Server Express 2005 and it works. Note that INSTEAD OF triggers do not cause recursion if you insert into the same table for which the trigger is defined.

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

Apache Commons Collection class.

StringUtils.equalsAny(CharSequence string, CharSequence... searchStrings)

So in your case, it would be

StringUtils.equalsAny(str, "val1", "val2", "val3");

If you know the length of the extension, you can use x.slice(0, -4) (where 4 is the three characters of the extension and the dot).

If you don't know the length @John Hartsock regex would be the right approach.

If you'd rather not use regular expressions, you can try this (less performant):

filename.split('.').slice(0, -1).join('.')

Note that it will fail on files without extension.

#if !defined(MANUF) || !defined(SERIAL) || !defined(MODEL)

Seems like problem of the old smtplib. In python2.7 everything works fine.

Update: Yep, server.ehlo() also could help.

The only reason to have a return in a void function would be to exit early due to some conditional statement:

void foo(int y)
{
    if(y == 0) return;

    // do stuff with y
}

As unwind said: when the code ends, it ends. No need for an explicit return at the end.

In Posgresql you could use ~

For example you could search for all rows that have col_a with any letter in lowercase

select * from your_table where col_a '[a-z]';

You could modify the Regex expression according your needs.

In the web a stateful protocol is based on having a temporary token that is exchanged between a browser and a server (via cookie header or URI rewriting) on every request. That token is usually created on the server end, and it is a piece of opaque data that has a certain time-to-live, and it has the sole purpose of identifying a specific web user agent. That is, the token is temporary, and becomes a STATE that the web server has to maintain on behalf of a client user agent during the duration of that conversation. Therefore, the communication using a token in this way is STATEFUL. And if the conversation between client and server is STATEFUL it is not RESTful.

The username/password (sent on the Authorization header) is usually persisted on the database with the intent of identifying a user. Sometimes the user could mean another application; however, the username/password is NEVER intended to identify a specific web client user agent. The conversation between a web agent and server based on using the username/password in the Authorization header (following the HTTP Basic Authorization) is STATELESS because the web server front-end is not creating or maintaining any STATE information whatsoever on behalf of a specific web client user agent. And based on my understanding of REST, the protocol states clearly that the conversation between clients and server should be STATELESS. Therefore, if we want to have a true RESTful service we should use username/password (Refer to RFC mentioned in my previous post) in the Authorization header for every single call, NOT a sension kind of token (e.g. Session tokens created in web servers, OAuth tokens created in authorization servers, and so on).

I understand that several called REST providers are using tokens like OAuth1 or OAuth2 accept-tokens to be be passed as "Authorization: Bearer " in HTTP headers. However, it appears to me that using those tokens for RESTful services would violate the true STATELESS meaning that REST embraces; because those tokens are temporary piece of data created/maintained on the server side to identify a specific web client user agent for the valid duration of a that web client/server conversation. Therefore, any service that is using those OAuth1/2 tokens should not be called REST if we want to stick to the TRUE meaning of a STATELESS protocol.

var wrapper = $(document.body);

strings = [

You can also add an Image to the Media Gallery by intent, have a look at the example code to see how it is done:

ContentValues image = new ContentValues();

image.put(Images.Media.TITLE, imageTitle);
image.put(Images.Media.DISPLAY_NAME, imageDisplayName);
image.put(Images.Media.DESCRIPTION, imageDescription);
image.put(Images.Media.DATE_ADDED, dateTaken);
image.put(Images.Media.DATE_TAKEN, dateTaken);
image.put(Images.Media.DATE_MODIFIED, dateTaken);
image.put(Images.Media.MIME_TYPE, "image/png");
image.put(Images.Media.ORIENTATION, 0);

 File parent = imageFile.getParentFile();
 String path = parent.toString().toLowerCase();
 String name = parent.getName().toLowerCase();
 image.put(Images.ImageColumns.BUCKET_ID, path.hashCode());
 image.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, name);
 image.put(Images.Media.SIZE, imageFile.length());

 image.put(Images.Media.DATA, imageFile.getAbsolutePath());

 Uri result = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, image);

The canonical examples are __declspec(dllimport) and __declspec(dllexport), which instruct the linker to import and export (respectively) a symbol from or to a DLL.

// header
__declspec(dllimport) void foo();


// code - this calls foo() somewhere in a DLL
foo();

(__declspec(..) just wraps up Microsoft's specific stuff - to achieve compatibility, one would usually wrap it away with macros)

Just wanted to make a time comparison for both solutions (for 30K rows DF):

In [1]: df = DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3], 'new':['apple', 'banana', 'pear']})

In [2]: big = pd.concat([df] * 10**4, ignore_index=True)

In [3]: big.shape
Out[3]: (30000, 3)

In [4]: %timeit big.apply(lambda x:'%s_%s_%s' % (x['bar'],x['foo'],x['new']),axis=1)
1 loop, best of 3: 881 ms per loop

In [5]: %timeit big['bar'].astype(str)+'_'+big['foo']+'_'+big['new']
10 loops, best of 3: 44.2 ms per loop

a few more options:

In [6]: %timeit big.ix[:, :-1].astype(str).add('_').sum(axis=1).str.cat(big.new)
10 loops, best of 3: 72.2 ms per loop

In [11]: %timeit big.astype(str).add('_').sum(axis=1).str[:-1]
10 loops, best of 3: 82.3 ms per loop

This error happened in my case when secure-file-priv was pointing to unexistent folder, make sure it exists and readable.

The line of code example in my.ini: secure-file-priv="D:/MySQL/uploads"

Do like this:

HTML

<div class="parent">
    <div class="child"></div>
    <div class="child"></div>
</div>

CSS

.parent{
    width: 400px;
    background: red;
}
.child{
    float: left;
    width:200px;
    background:green;
    height: 100px;
}

This is working jsfiddle. Change child width to more then 200px and they will stack.

I got this error because I was doing File.Move to a file path without a file name, need to specify the full path in the destination.

First quote your javascript:

onclick="hello();"

Also you can't call a php function from javascript; you need:

<script type="text/javascript">
function hello()
{
alert ("hello");
}
</script>

check Robocopy:

ROBOCOPY \\server-source\c$\VMExports\ C:\VMExports\ /E /COPY:DAT

make sure you check what robocopy parameter you want. this is just an example. type robocopy /? in a comandline/powershell on your windows system.

Sometimes using only the line below throws me an Exception,

String text = listView1.SelectedItems[0].Text; 

so I use this code below:

private void listView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    if (listView1.SelectedIndices.Count <= 0) 
    { 
        return; 
    } 
    int intselectedindex = listView1.SelectedIndices[0]; 
    if (intselectedindex >= 0) 
    {
        String text = listView1.Items[intselectedindex].Text;

        //do something
        //MessageBox.Show(listView1.Items[intselectedindex].Text); 
    } 
}

There's no supported way to do this, but won't you have to examine the files related to each installer to figure out how to actually install them after extracting them? Assuming you can spend the time to figure out which command-line applies, here are some candidate parameters that normally allow you to extract an installation.

MSI Based (may not result in a usable image for an InstallScript MSI installation):

• setup.exe /a /s /v"/qn TARGETDIR=\"choose-a-location\""

  or, to also extract prerequisites (for versions where it works),

• setup.exe /a"choose-another-location" /s /v"/qn TARGETDIR=\"choose-a-location\""

InstallScript based:

• setup.exe /s /extract_all

Suite based (may not be obvious how to install the resulting files):

• setup.exe /silent /stage_only ISRootStagePath="choose-a-location"

This is the fastest& clean way to do that :

I'm using Jquery-->

$('selector').on('change', function () {
    console.log(this.id+": "+ this.value);
});

It is working pretty fine for me.

This is the most correct answer for IE and Chrome::

javascript=>

var element = document.getElementById('xxxx');
var evt = document.createEvent('HTMLEvents');
evt.initEvent('change', false, true);
element.dispatchEvent(evt);

I find this simple T-SQL query useful for returning valid e-mail addresses

SELECT email
FROM People
WHERE email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0

The PATINDEX bit eliminates all e-mail addresses containing characters that are not in the allowed a-z, 0-9, '@', '.', '_' & '-' set of characters.

It can be reversed to do what you want like this:

SELECT email
FROM People
WHERE NOT (email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0)

COPY description_f (id, name) FROM 'absolutepath\test.txt' WITH (FORMAT csv, HEADER true, DELIMITER '   ');

Example

COPY description_f (id, name) FROM 'D:\HIVEWORX\COMMON\TermServerAssets\Snomed2021\SnomedCT\Full\Terminology\sct2_Description_Full_INT_20210131.txt' WITH (FORMAT csv, HEADER true, DELIMITER ' ');

If it's for debugging, just add a css class for hovering (since elements can have more than one class):

a.hovertest:hover
{
text-decoration:underline;
}

<a href="http://example.com" class="foo bar hovertest">blah</a>

Querydsl and jOOQ are two popular choices.

You must use a .ts file - e.g. test.ts to get Typescript validation, intellisense typing of vars, return types, as well as "typed" error checking (e.g. passing a string to a method that expects an number param will error out).

It will be transpiled into (standard) .js via tsc.

Update (11/2018):

Clarification needed based on down-votes, very helpful comments and other answers.

types

• Yes, you can do type checking in VS Code in .js files with @ts-check - as shown in the animation

• What I originally was referring to for Typescript types is something like this in .ts which isn't quite the same thing:

  hello-world.ts

  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  This will not compile. Error: Type "1" is not assignable to String

• if you tried this syntax in a Javascript hello-world.js file:

  //@ts-check
  
  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  The error message referenced by OP is shown: [js] 'types' can only be used in a .ts file

If there's something I missed that covers this as well as the OP's context, please add. Let's all learn.

MACRO Solution (2020)

Here is the macro that I use for safe string instead of getting "(null)" string on a UILabel for example:

#define SafeString(STRING) ([STRING length] == 0 ? @"" : STRING)

let say you have an member class and name property, and name is nil:

NSLog(@"%@", member.name); // prints (null) on UILabel

with macro:

NSLog(@"%@", SafeString(member.name)); // prints empty string on UILabel

nice and clean

Extension Solution (2020)

If you prefer checking nil Null and empty string in your project you can use my extension line below:

NSString+Extension.h

///
/// Checks if giving String is an empty string or a nil object or a Null.
/// @param string string value to check.
///
+ (BOOL)isNullOrEmpty:(NSString*)string;

NSString+Extension.m

+ (BOOL)isNullOrEmpty:(NSString*)string {
    if (string) { // is not Nil
        NSRange range = [string rangeOfString:string];
        BOOL isEmpty = (range.length <= 0 || [string isEqualToString:@" "]);
        BOOL isNull = string == (id)[NSNull null];

        return (isNull || isEmpty);
    }

    return YES;
}

Example Usage

if (![NSString isNullOrEmpty:someTitle]) {
    // You can safely use on a Label or even add in an Array for example. Remember: Arrays don't like the nil values!
}

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

From crtdbg.h (and many other headers):

#ifndef NULL
#ifdef __cplusplus
#define NULL    0
#else
#define NULL    ((void *)0)
#endif
#endif

Therefore NULL is 0, at least on the Windows platform. So no, not that I know of.

Alternatively, if you want to export a copy without modifying the working copy, you can use rsync:

rsync -a --exclude .svn path/to/working/copy path/to/export

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

From Java How to Program about abstract classes:

Because they’re used only as superclasses in inheritance hierarchies, we refer to them as abstract superclasses. These classes cannot be used to instantiate objects, because abstract classes are incomplete. Subclasses must declare the “missing pieces” to become “concrete” classes, from which you can instantiate objects. Otherwise, these subclasses, too, will be abstract.

To answer your question "What is the reason to use interfaces?":

An abstract class’s purpose is to provide an appropriate superclass from which other classes can inherit and thus share a common design.

As opposed to an interface:

An interface describes a set of methods that can be called on an object, but does not provide concrete implementations for all the methods... Once a class implements an interface, all objects of that class have an is-a relationship with the interface type, and all objects of the class are guaranteed to provide the functionality described by the interface. This is true of all subclasses of that class as well.

So, to answer your question "I was wondering when I should use interfaces", I think you should use interfaces when you want a full implementation and use abstract classes when you want partial pieces for your design (for reusability)

Difference between STATIC MEMORY ALLOCATION & DYNAMIC MEMORY ALLOCATION

Memory is allocated before the execution of the program begins (During Compilation).
Memory is allocated during the execution of the program.

No memory allocation or deallocation actions are performed during Execution.
Memory Bindings are established and destroyed during the Execution.

Variables remain permanently allocated.
Allocated only when program unit is active.

Implemented using stacks and heaps.
Implemented using data segments.

Pointer is needed to accessing variables.
No need of Dynamically allocated pointers.

Faster execution than Dynamic.
Slower execution than static.

More memory Space required.
Less Memory space required.

   <p class="filename">keyword</p>
   <p class="content">keyword</p>
   <p class="system"><i>keyword</i></p>
</body>

JS

$(document).ready(function() {
   var keyWord = $("#lblKeyword").text(); 
   var replaceD = "<span class='highlight'>" + keyWord + "</span>";
   $(".system, .filename, .content").each(function() {
      var text = $(this).text();

Use ascii_bin where ever possible, it will match up with almost any collation. A username seldom accepts special characters anyway.

You could make the element containing the bg text have a lower stacking order ( z-index, position ) and possibly even set opacity. So the element you need on top would need a higher stacking order ( z-index:5; position:relative; for ex ) and the element behind would need something lower ( default or just a lower z-index like 3 and position:relative; ).

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

The solutions that search a file for a substring can also search a string, eg. find or findstr.
In your case, the easy solution would be to pipe a string into the command instead of supplying a filename eg.

case-sensitive string:
echo "abcdefg" | find "bcd"

ignore case of string:
echo "abcdefg" | find /I "bcd"

IF no match found, you will get a blank line response on CMD and %ERRORLEVEL% set to 1

Try this;

@media print{ @page { margin-top: 30px; margin-bottom: 30px;}}

replot

This is another way to get multiple plots at once:

plot file1.data
replot file2.data

It's an old question. A lot of good things happened since then. Here are my two cents on this topic:

1. To accurately track the visited pages you have to normalize URI first. The normalization algorithm includes multiple steps:

   • Sort query parameters. For example, the following URIs are equivalent after normalization: GET http://www.example.com/query?id=111&cat=222 GET http://www.example.com/query?cat=222&id=111

   • Convert the empty path. Example: http://example.org ? http://example.org/

   • Capitalize percent encoding. All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive. Example: http://example.org/a%c2%B1b ? http://example.org/a%C2%B1b

   • Remove unnecessary dot-segments. Example: http://example.org/../a/b/../c/./d.html ? http://example.org/a/c/d.html

   • Possibly some other normalization rules

2. Not only <a> tag has href attribute, <area> tag has it too https://html.com/tags/area/. If you don't want to miss anything, you have to scrape <area> tag too.

3. Track crawling progress. If the website is small, it is not a problem. Contrarily it might be very frustrating if you crawl half of the site and it failed. Consider using a database or a filesystem to store the progress.

4. Be kind to the site owners. If you are ever going to use your crawler outside of your website, you have to use delays. Without delays, the script is too fast and might significantly slow down some small sites. From sysadmins perspective, it looks like a DoS attack. A static delay between the requests will do the trick.

If you don't want to deal with that, try Crawlzone and let me know your feedback. Also, check out the article I wrote a while back https://www.codementor.io/zstate/this-is-how-i-crawl-n98s6myxm

Swift 5 and above

DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: {
   // code to execute                 
})

A common mistake is

mainWB.Sheets.Add(After:=Sheets.Count)

which leads to Error 1004. Although it is not clear at all from the official documentation, it turns out that the 'After' parameter cannot be an integer, it must be a reference to a sheet in the same workbook.

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

The newer android phones in the market like HTC one, Xperia Z etc have resolutions in the >480dpi range, putting them in the new xxhdpi class as well. The new assets might be useful for them too.

This is what I did and it's fast and works perfectly:

function isIPv4Address(inputString) {
    let regex = new RegExp(/^(([0-9]{1,3}\.){3}[0-9]{1,3})$/);
    if(regex.test(inputString)){
        let arInput = inputString.split(".")
        for(let i of arInput){
            if(i.length > 1 && i.charAt(0) === '0')
                return false;
            else{
                if(parseInt(i) < 0 || parseInt(i) >=256)
                   return false;
            }
        }
    }
    else
        return false;
    return true;
}

Explanation: First, with the regex check that the IP format is correct. Although, the regex won't check any value ranges.

I mean, if you can use Javascript to manage regex, why not use it?. So, instead of using a crazy regex, use Regex only for checking that the format is fine and then check that each value in the octet is in the correct value range (0 to 255). Hope this helps anybody else. Peace.

just to add another example of what a lambda can do without using map:

a = 10
b = 2

var mixed = (a,b) => a * b; 
// OR
var mixed = (a,b) => { (any logic); return a * b };

console.log(mixed(a,b)) 
// 20

Try using a single quote instead of double quotes along with -g

Following scenario worked for me

curl -g -d '{"collection":[{"NumberOfParcels":1,"Weight":1,"Length":1,"Width":1,"Height":1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST  https://yoururl.com

This especially resolved my error curl command error : bad url colon is first character

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C
double              D
float               F
int                 I
long                J
short               S 
class or interface  Lclassname;

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace').

As the first answer indicated, currently there is no way to rename components so we're all just talking about work-arounds! This is what i do:

1. Create the new component you liked.

   ng generate component newName

2. Use Visual studio code editor or whatever other editor to then conveniently move code/pieces side by side!

3. In Linux, use grep & sed (find & replace) to find/replaces references.

   grep -ir "oldname"

   cd your folder

   sed -i 's/oldName/newName/g' *

We use @Temporal annotation to insert date, time or both in database table.Using TemporalType we can insert data, time or both int table.

@Temporal(TemporalType.DATE) // insert date
@Temporal(TemporalType.TIME) // insert time
@Temporal(TemporalType.TIMESTAMP) // insert  both time and date.

I hope this is helpful.

        T1 = 0,
        T2 = 1,

    }

get string value

string enumValueString = "T1";

        List<string> stringValueList =  typeof(TESTENUM).GetEnumValues().Cast<object>().Select(m => 
            Convert.ToString(m)
            ).ToList();

        }

        TESTENUM testEnumValueConvertString;
        Enum.TryParse<TESTENUM>(enumValueString, out testEnumValueConvertString);

get integer value

        int enumValueInt = 1;

        List<int> enumValueIntList =  typeof(TESTENUM).GetEnumValues().Cast<object>().Select(m =>
            Convert.ToInt32(m)
            ).ToList();

With python3, iterate on dic.keys() will raise the dictionary size error. You can use this alternative way:

Tested with python3, it works fine and the Error "dictionary changed size during iteration" is not raised:

my_dic = { 1:10, 2:20, 3:30 }
# Is important here to cast because ".keys()" method returns a dict_keys object.
key_list = list( my_dic.keys() )

# Iterate on the list:
for k in key_list:
    print(key_list)
    print(my_dic)
    del( my_dic[k] )


print( my_dic )
# {}

In addition to gmaggio's answer if you need to dynamically REPLACE and UPDATE according to another column you can do for example:

UPDATE your_table t1
INNER JOIN other_table t2
ON t1.field_id = t2.field_id
SET t1.your_field = IF(LOCATE('articles/updates/', t1.your_field) > 0, 
REPLACE(t1.your_field, 'articles/updates/', t2.new_folder), t1.your_field) 
WHERE...

In my example the string articles/news/ is stored in other_table t2 and there is no need to use LIKE in the WHERE clause.

If your HTML contains heavy HTML-contents like iframe's (i.e. facebook-, twitter, instagram-embeds) the real solution is much more difficult, first wrap your HTML:

[htmlContent appendFormat:@"<html>", [[LocalizationStore instance] currentTextDir], [[LocalizationStore instance] currentLang]];
[htmlContent appendFormat:@"<head>"];
[htmlContent appendString:@"<script type=\"text/javascript\">"];
[htmlContent appendFormat:@"    var lastHeight = 0;"];
[htmlContent appendFormat:@"    function updateHeight() { var h = document.getElementById('content').offsetHeight; if (lastHeight != h) { lastHeight = h; window.location.href = \"x-update-webview-height://\" + h } }"];
[htmlContent appendFormat:@"    window.onload = function() {"];
[htmlContent appendFormat:@"        setTimeout(updateHeight, 1000);"];
[htmlContent appendFormat:@"        setTimeout(updateHeight, 3000);"];
[htmlContent appendFormat:@"        if (window.intervalId) { clearInterval(window.intervalId); }"];
[htmlContent appendFormat:@"        window.intervalId = setInterval(updateHeight, 5000);"];
[htmlContent appendFormat:@"        setTimeout(function(){ clearInterval(window.intervalId); window.intervalId = null; }, 30000);"];
[htmlContent appendFormat:@"    };"];
[htmlContent appendFormat:@"</script>"];
[htmlContent appendFormat:@"..."]; // Rest of your HTML <head>-section
[htmlContent appendFormat:@"</head>"];
[htmlContent appendFormat:@"<body>"];
[htmlContent appendFormat:@"<div id=\"content\">"]; // !important https://stackoverflow.com/a/8031442/1046909
[htmlContent appendFormat:@"..."]; // Your HTML-content
[htmlContent appendFormat:@"</div>"]; // </div id="content">
[htmlContent appendFormat:@"</body>"];
[htmlContent appendFormat:@"</html>"];

Then add handling x-update-webview-height-scheme into your shouldStartLoadWithRequest:

    if (navigationType == UIWebViewNavigationTypeLinkClicked || navigationType == UIWebViewNavigationTypeOther) {
    // Handling Custom URL Scheme
    if([[[request URL] scheme] isEqualToString:@"x-update-webview-height"]) {
        NSInteger currentWebViewHeight = [[[request URL] host] intValue];
        if (_lastWebViewHeight != currentWebViewHeight) {
            _lastWebViewHeight = currentWebViewHeight; // class property
            _realWebViewHeight = currentWebViewHeight; // class property
            [self layoutSubviews];
        }
        return NO;
    }
    ...

And finally add the following code inside your layoutSubviews:

    ...
    NSInteger webViewHeight = 0;

    if (_realWebViewHeight > 0) {
        webViewHeight = _realWebViewHeight;
        _realWebViewHeight = 0;
    } else {
        webViewHeight = [[webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"content\").offsetHeight;"] integerValue];
    }

    upateWebViewHeightTheWayYorLike(webViewHeight);// Now your have real WebViewHeight so you can update your webview height you like.
    ...

P.S. You can implement time delaying (SetTimeout and setInterval) inside your ObjectiveC/Swift-code - it's up to you.

P.S.S. Important info about UIWebView and Facebook Embeds: Embedded Facebook post does not shows properly in UIWebView

In case anyone else runs into this. I have a web site that was working fine on the desktop browser but I was getting 400 errors with Android devices.

It turned out to be the anti forgery token.

$.ajax({
        url: "/Cart/AddProduct/",
        data: {
            __RequestVerificationToken: $("[name='__RequestVerificationToken']").val(),
            productId: $(this).data("productcode")
        },

The problem was that the .Net controller wasn't set up correctly.

I needed to add the attributes to the controller:

    [AllowAnonymous]
    [IgnoreAntiforgeryToken]
    [DisableCors]
    [HttpPost]
    public async Task<JsonResult> AddProduct(int productId)
    {

The code needs review but for now at least I know what was causing it. 400 error not helpful at all.

if you are using cp doesn't save existing files when copying folders of the same name. Lets say you have this folders:

/myFolder
  someTextFile.txt

/someOtherFolder
  /myFolder

Then you copy one over the other:

cp /someOtherFolder/myFolder /myFolder

result:

/myFolder

I ended up blending Joe White's answer and some code from Adam Mills's answer, since I needed to show a user control in a programmatically created window. So the DialogCloser need not be on the window, it can be on the user control itself

<UserControl ...
    xmlns:xw="clr-namespace:Wpf"
    xw:DialogCloser.DialogResult="{Binding DialogResult}">

And the DialogCloser will find the window of the user control if it was not attached to the window itself.

namespace Wpf
{
  public static class DialogCloser
  {
    public static readonly DependencyProperty DialogResultProperty =
        DependencyProperty.RegisterAttached(
            "DialogResult",
            typeof(bool?),
            typeof(DialogCloser),
            new PropertyMetadata(DialogResultChanged));

    private static void DialogResultChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs e)
    {
      var window = d.GetWindow();
      if (window != null)
        window.DialogResult = e.NewValue as bool?;
    }

    public static void SetDialogResult(DependencyObject target, bool? value)
    {
      target.SetValue(DialogResultProperty, value);
    }
  }

  public static class Extensions
  {
    public static Window GetWindow(this DependencyObject sender_)
    {
      Window window = sender_ as Window;        
      return window ?? Window.GetWindow( sender_ );
    }
  }
}

To simplify the above:

text.substring(0, text.indexOf(' ')); 

Here is a ready function:

private String getFirstWord(String text) {

  int index = text.indexOf(' ');

  if (index > -1) { // Check if there is more than one word.

    return text.substring(0, index).trim(); // Extract first word.

  } else {

    return text; // Text is the first word itself.
  }
}

in your for loop use a Redim on the array like here:

For i = 0 to 3
  ReDim Preserve test(i)
  test(i) = 3 + i
Next i

A simple class that can wrap a dict, and retrieve based on a key:

class FindKey(dict):
    def get(self, path, default=None):
        keys = path.split(".")
        val = None

        for key in keys:
            if val:
                if isinstance(val, list):
                    val = [v.get(key, default) if v else None for v in val]
                else:
                    val = val.get(key, default)
            else:
                val = dict.get(self, key, default)

            if not val:
                break

        return val

For example:

person = {'person':{'name':{'first':'John'}}}
FindDict(person).get('person.name.first') # == 'John'

If the key doesn't exist, it returns None by default. You can override that using a default= key in the FindDict wrapper -- for example`:

FindDict(person, default='').get('person.name.last') # == doesn't exist, so ''

You can also try to use a Polyfill like Fixed-Sticky. Especially when you are using Bootstrap4 the affix component is no longer included:

Dropped the Affix jQuery plugin. We recommend using a position: sticky polyfill instead.

First, You have to install the Android Studio and Xcode to create phone emulator.

In VSCode you can use the Android IOS Emulator plugin to set the path of emulator to run.

It's worth reading Oracle Java Tutorial - Getting and Setting Field Values

Field#set(Object object, Object value) sets the field represented by this Field object on the specified object argument to the specified new value.

It should be like this

f.set(objectOfTheClass, new ConcurrentHashMap<>());

You can't set any value in null Object If tried then it will result in NullPointerException

Note: Setting a field's value via reflection has a certain amount of performance overhead because various operations must occur such as validating access permissions. From the runtime's point of view, the effects are the same, and the operation is as atomic as if the value was changed in the class code directly.

The algo will need to work on the following model,

• keep track of the head
• Recurse till end of linklist
• Reverse linkage

Structure:

Head    
|    
1-->2-->3-->4-->N-->null

null-->1-->2-->3-->4-->N<--null

null-->1-->2-->3-->4<--N<--null

null-->1-->2-->3<--4<--N<--null

null-->1-->2<--3<--4<--N<--null

null-->1<--2<--3<--4<--N<--null

null<--1<--2<--3<--4<--N
                       |
                       Head

Code:

public ListNode reverse(ListNode toBeNextNode, ListNode currentNode)
{               
        ListNode currentHead = currentNode; // keep track of the head

        if ((currentNode==null ||currentNode.next==null )&& toBeNextNode ==null)return currentHead; // ignore for size 0 & 1

        if (currentNode.next!=null)currentHead = reverse(currentNode, currentNode.next); // travarse till end recursively

        currentNode.next = toBeNextNode; // reverse link

        return currentHead;
}

Output:

head-->12345

head-->54321

just set position: fixed to the footer element (instead of relative)

Jsbin example

Note that you may need to also set a margin-bottom to the main element at least equal to the height of the footer element (e.g. margin-bottom: 1.5em;) otherwise, in some circustances, the bottom area of the main content could be partially overlapped by your footer

Store the return of setInterval in a variable, and use it later to clear the interval.

var timer = null;
$("textarea").blur(function(){
    timer = window.setInterval(function(){ ... whatever ... }, 2000);
}).focus(function(){
    if(timer){
       window.clearInterval(timer);
       timer = null
    }
});

@Query("SELECT DISTINCT name FROM people WHERE name NOT IN (:names)")
List<String> findNonReferencedNames(@Param("names") List<String> names);

Choosing a random pivot minimizes the chance that you will encounter worst-case O(n²) performance (always choosing first or last would cause worst-case performance for nearly-sorted or nearly-reverse-sorted data). Choosing the middle element would also be acceptable in the majority of cases.

Also, if you are implementing this yourself, there are versions of the algorithm that work in-place (i.e. without creating two new lists and then concatenating them).

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

The best is to try to use ONLY_FULL_GROUP_BY on new projects while remaining backward compatible on existing sites and databases. For this I opted for a modification of the SQL Mode when loading mysqli, respectively PDO in my classes.

For mysqli :

mysqli_query($this->link,"SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))");

For PDO class :

PDO::MYSQL_ATTR_INIT_COMMAND => "SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"

Example with PDO init :

try {
    $dns     = 'mysql:host=localhost;dbname=' . $prod_db;
    $user    = _DBUSER_;
    $pass    = _DBPASS_;
    $options = array(
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"
    );

    $db = new PDO($dns, $user, $pass, $options);
} 

catch(Exception $e) {
    mail("[email protected]","Database Error ",$dns.",".$user);
    echo "Unable ot connect to mySQL : ", $e->getMessage();
    die();
} 

Thus, the new classes created on the same server will work with new standard of databases.

This worked for me:

/* Headers */
require('./security/Headers/HeadersOptions').Headers(app);

/* Server */
const ssl = {
    key: fs.readFileSync('security/ssl/cert.key'),
    cert: fs.readFileSync('security/ssl/cert.pem')
};
//https server
https.createServer(ssl, app).listen(443, '192.168.1.2' && 443, '127.0.0.1');
//http server
app.listen(80, '192.168.1.2' && 80, '127.0.0.1');
app.use(function(req, res, next) {
    if(req.secure){
        next();
    }else{
        res.redirect('https://' + req.headers.host + req.url);
    }
});

Recommend add the headers before redirect to https

Now, when you do:

curl http://127.0.0.1 --include

You get:

HTTP/1.1 302 Found
//
Location: https://127.0.0.1/
Vary: Accept
Content-Type: text/plain; charset=utf-8
Content-Length: 40

Found. Redirecting to https://127.0.0.1/

I use express 4.17.1

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

The document says:

Copy the file into the app/ folder of your Android Studio project, or into the app/src/{build_type} folder if you are using multiple build types.

Strace is a tool that tells you how your application interacts with your operating system.

It does this by telling you what OS system calls your application uses and with what parameters it calls them.

So for instance you see what files your program tries to open, and weather the call succeeds.

You can debug all sorts of problems with this tool. For instance if application says that it cannot find library that you know you have installed you strace would tell you where the application is looking for that file.

And that is just a tip of the iceberg.

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/

simple just use the img tag helper. Rails knows to look in the images folder in the asset pipeline, you can use it like this

<%= image_tag "image.jpg" %>

Since IntelliJ 2016, the location is File | Settings | Build, Execution, Deployment | Compiler | Build process heap size.

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

For Windows Forms applications an optional disabling of a UI-Control can be very useful. So my suggestion looks like this:

public class AppWaitCursor : IDisposable
{
    private readonly Control _eventControl;

    public AppWaitCursor(object eventSender = null)
    {
         _eventControl = eventSender as Control;
        if (_eventControl != null)
            _eventControl.Enabled = false;

        Application.UseWaitCursor = true;
        Application.DoEvents();
    }

    public void Dispose()
    {
        if (_eventControl != null)
            _eventControl.Enabled = true;

        Cursor.Current = Cursors.Default;
        Application.UseWaitCursor = false;
    }
}

Usage:

private void UiControl_Click(object sender, EventArgs e)
{
    using (new AppWaitCursor(sender))
    {
        LongRunningCall();
    }
}

If you have more complex requirements than just the top directory (eg ignore VCS dirs etc), you can also modify the list of directories to prevent os.walk recursing through them.

ie:

def _dir_list(self, dir_name, whitelist):
    outputList = []
    for root, dirs, files in os.walk(dir_name):
        dirs[:] = [d for d in dirs if is_good(d)]
        for f in files:
            do_stuff()

Note - be careful to mutate the list, rather than just rebind it. Obviously os.walk doesn't know about the external rebinding.

Use .form-group.required without the space.

.form-group.required .control-label:after {
  content:"*";
  color:red;
}

Edit:

.form-group.required:not(.checkbox) .control-label:after, 
.form-group.required .text:after { /* change .text in whatever class of the text after the checkbox has */
   content:"*";
   color:red;
}

<div class="form-group required">
   <label class="col-md-2 control-label">&#160;</label>
   <div class="col-md-4">
      <div class="checkbox">
         <label class='text'> <!-- use this class -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

Ok third edit:

CSS back to what is was

.form-group.required .control-label:after { 
   content:"*";
   color:red;
}

HTML:

<div class="form-group required">
   <label class="col-md-2">&#160;</label> <!-- remove class control-label -->
   <div class="col-md-4">
      <div class="checkbox">
         <label class='control-label'> <!-- use this class as the red * will be after control-label -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

In the __init__ method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called.

self, as a name, is just a convention, call it as you want ! but when using it, for example to delete the object, you have to use the same name: __del__(var), where var was used in the __init__(var,[...])

You should take a look at cls too, to have the bigger picture. This post could be helpful.

shuckc's answer for echoing select lines has a few downsides: you end up with the following set +x command being echoed as well, and you lose the ability to test the exit code with $? since it gets overwritten by the set +x.

Another option is to run the command in a subshell:

echo "getting URL..."
( set -x ; curl -s --fail $URL -o $OUTFILE )

if [ $? -eq 0 ] ; then
    echo "curl failed"
    exit 1
fi

which will give you output like:

getting URL...
+ curl -s --fail http://example.com/missing -o /tmp/example
curl failed

This does incur the overhead of creating a new subshell for the command, though.

Finally come up with best way to do

String to = "[email protected]";
String subject= "Hi I am subject";
String body="Hi I am test body";
String mailTo = "mailto:" + to +
        "?&subject=" + Uri.encode(subject) +
        "&body=" + Uri.encode(body);
Intent emailIntent = new Intent(Intent.ACTION_VIEW);
emailIntent.setData(Uri.parse(mailTo));
startActivity(emailIntent);

I like the next style for rename dataframe column names one by one.

colnames(df)[which(colnames(df) == 'old_colname')] <- 'new_colname'

where

which(colnames(df) == 'old_colname')

returns by the index of the specific column.

My solution was https://yoksel.github.io/url-encoder/ You just simply insert your svg and getting back background-image code

If your app is written in TypeScript, try

(global as any).logger = // ...

or

Object.assign(global, { logger: // ... })

However, I will do it only when React Native's __DEV__ in testing environment.

Here's a dictionary that will take any type of key as long as the toString() property returns unique values. The dictionary uses anything as the value for the key value pair.

See Would JavaScript Benefit from a Dictionary Object.

To use the dictionary as is:

var dictFact = new Dict();
var myDict = dictFact.New();
myDict.addOrUpdate("key1", "Value1");
myDict.addOrUpdate("key2", "Value2");
myDict.addOrUpdate("keyN", "ValueN");

In /etc/subversion/servers you are setting http-proxy-host, which has nothing to do with svn:// which connects to a different server usually running on port 3690 started by svnserve command.

If you have access to the server, you can setup svn+ssh:// as explained here.

Update: You could also try using connect-tunnel, which uses your HTTPS proxy server to tunnel connections:

connect-tunnel -P proxy.company.com:8080 -T 10234:svn.example.com:3690

Then you would use

svn checkout svn://localhost:10234/path/to/trunk

You can use JavaScript like... Just give the proper path of your json file...

<!doctype html>
<html>
    <head>
        <script type="text/javascript" src="abc.json"></script>
        <script type="text/javascript" >
            function load() {
                var mydata = JSON.parse(data);
                alert(mydata.length);

                var div = document.getElementById('data');

                for(var i = 0;i < mydata.length; i++)
                {
                    div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
                }
            }
        </script>
    </head>
    <body onload="load()">
        <div id="data">

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

Simply getting the data and appending it to a div... Initially printing the length in alert.

Here is my Json file: abc.json

data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';

Depends on. Briefly... If you want load variables on current console and execute you may use source myshellfile.sh on your code. Example:

!#/bin/bash
set -x
echo "This is an example of run another INTO this session."
source my_lib_of_variables_and_functions.sh
echo "The function internal_function() is defined into my lib."
returned_value=internal_function()
echo $this_is_an_internal_variable

set +x

If you just want to execute a file and the only thing intersting for you is the result, you can do:

!#/bin/bash
set -x
./executing_only.sh
sh i_can_execute_this_way_too.sh
bash or_this_way.sh
set +x

I hope helps you. Thanks.

For those who are looking for PHP ( >5.3.5 ) PDO statement, we can set charset as per below:

$dbh = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');

var mouseX;
var mouseY;
$(document).mousemove( function(e) {
   mouseX = e.pageX; 
   mouseY = e.pageY;
});  
$(".classForHoverEffect").mouseover(function(){
  $('#DivToShow').css({'top':mouseY,'left':mouseX}).fadeIn('slow');
});

the function above will make the DIV appear over the link wherever that may be on the page. It will fade in slowly when the link is hovered. You could also use .hover() instead. From there the DIV will stay, so if you would like the DIV to disappear when the mouse moves away, then,

$(".classForHoverEffect").mouseout(function(){
  $('#DivToShow').fadeOut('slow');
});

If you DIV is already positioned, you can simply use

$('.classForHoverEffect').hover(function(){
  $('#DivToShow').fadeIn('slow');
});

Also, keep in mind, your DIV style needs to be set to display:none; in order for it to fadeIn or show.

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

--- To set java path ---

There are two ways to set java path

A. Temporary

1. Open cmd
2. Write in cmd : javac

If java is not installed, then you will see message:

javac is not recognized as internal or external command, operable program or batch file.

3. Write in cmd : set path=C:\Program Files\Java\jdk1.8.0_121\bin
4. Write in cmd : javac

You can check that path is set if not error has been raised.

It is important to note that these changes are only temporary from programs launched from this cmd.

NOTE: You might have to run the command line as admin

B. Permanent

1. Righ-click on "My computer" and click on properties
2. Click on "Advanced system settings"
3. Click on "Environment variables"
4. Click on new tab of user variable
5. Write path in variable name
6. Copy the path of bin folder
7. Paste the path of the bin folder in the variable value
8. Click OK

The path is now set permanently.

TIP: The tool "Rapid Environment Editor" (freeware) is great for modifying the environment variables and useful in that case

TIP2: There is also a faster way to access the Environment Variables: press Win+R keys, paste the following %windir%\System32\rundll32.exe sysdm.cpl,EditEnvironmentVariables and press ENTER

Sublime

I think you could do:

$('#google_translate_element').find('*').each(function(){
    $(this).unbind('click');
});

but it would cause a lot of overhead

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

Thanks to tmoschou for adding this comment to an outdated accepted answer:

As of Ansible 2.10, The documentation for ansible.builtin.copy says: 

If you need variable interpolation in copied files, use the
ansible.builtin.template module. Using a variable in the content field will
result in unpredictable output.

For more details see this and an explanation

Original answer:

You can use the copy module, with the parameter content=.

I gave the exact same answer here: Write variable to a file in Ansible

In your case, it looks like you want this variable written to a local logfile, so you could combine it with the local_action notation:

- local_action: copy content={{ foo_result }} dest=/path/to/destination/file

Below code works for me:

JsonConvert.SerializeObject(JToken.Parse(yourobj.ToString()))

for cordova developers having this issue

try to set

<preference name="deployment-target" value="8.0" />

in confix.xml

This can also be a issue when you enter wrong password for your sign key.

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

You can do that using the gacutil tool. In its simplest form:

gacutil /i yourdll.dll

You find the Visual Studio Command Prompt in the start menu under Programs -> Visual Studio -> Visual Studio Tools.

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

You need to use data: {title: title} to POST it correctly.

In the PHP code you need to echo the value instead of returning it.

What i have done is that import a new project into eclipse workspace, and that path of that was be

android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib

and add as library in your project.. that it .. simple!! you might require to add support library in your project.

What about element.tagName?

See also tagName docs on MDN.

strace is available from Cygwin in the cygwin package. You can download it from a Cygwin mirror, for example:

http://mirrors.sonic.net/cygwin/x86_64/release/cygwin/cygwin-2.0.2-1.tar.xz
#      |                      |                              |     |
#      +-----------+----------+                              +--+--+
#                  |                                            |
#               mirror                                       version

strace is one of the few Cygwin programs that does not rely on the Cygwin DLL, so you should be able to just copy strace.exe to where you want and use it.

It can depend on what your are initialising, for example you cannot just use field initialisation if a checked exception is involved. For example, the following:

public class Foo {
    FileInputStream fis = new FileInputStream("/tmp"); // throws FileNotFoundException
}

Will cause a compile-time error unless you also include a constructor declaring that checked exception, or extend a superclass which does, e.g.:

public Foo() throws FileNotFoundException {} 

No, it is not possible to change the content of the buttons in the dialog displayed by the confirm function. You can use Javascript to create a dialog that looks similar.

Yes, you can definitely do this. Just use something like

.parent:hover .child {
   /* ... */
}

According to this page it's supported by all major browsers.

In WSDL definition, bindings contain operations, here comes style for each operation.

Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.

• Advantage:
  • Using this Document style, we can validate SOAP messages against predefined schema. It supports xml datatypes and patterns.
  • loosely coupled.
• Disadvantage: It is a little bit hard to get understand.

In WSDL types element looks as follows:

<types>
 <xsd:schema>
  <xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
 </xsd:schema>
</types>

The schema is importing from external reference.

RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.

<types/>  
<message name="getHelloWorldAsString">  
<part name="arg0" type="xsd:string"/>  
</message>  
<message name="getHelloWorldAsStringResponse">  
<part name="return" type="xsd:string"/>  
</message>  

• Advantage: Easy to understand.
• Disadvantage:
  • we can not validate SOAP messages.
  • tightly coupled

RPC : No types in WSDL
Document: Types section would be available in WSDL

add display:block; and it'll work. Images are inline by default

To clarify, the default width for a block element is auto, which of course fills the entire available width of the containing element.

By setting the margin to auto, the browser assigns half the remaining space to margin-left and the other half to margin-right.

Select just column_name from information schema and put the result of this query into variable. Then test the variable to decide if table needs alteration or not.

P.S. Don't foget to specify TABLE_SCHEMA for COLUMNS table as well.

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

See also std::remove_if to be able to use a predicate...

Here's the example from the link above:

vector<int> V;
V.push_back(1);
V.push_back(4);
V.push_back(2);
V.push_back(8);
V.push_back(5);
V.push_back(7);

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 4 2 8 5 7"

vector<int>::iterator new_end = 
    remove_if(V.begin(), V.end(), 
              compose1(bind2nd(equal_to<int>(), 0),
                       bind2nd(modulus<int>(), 2)));
V.erase(new_end, V.end()); [1]

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 5 7".

Guys, I found that JQuery has only one effect: the page is reloaded when the back button is pressed. This has nothing to do with "ready".

How does this work? Well, JQuery adds an onunload event listener.

// http://code.jquery.com/jquery-latest.js
jQuery(window).bind("unload", function() { // ...

By default, it does nothing. But somehow this seems to trigger a reload in Safari, Opera and Mozilla -- no matter what the event handler contains.

[edit(Nickolay): here's why it works that way: webkit.org, developer.mozilla.org. Please read those articles (or my summary in a separate answer below) and consider whether you really need to do this and make your page load slower for your users.]

Can't believe it? Try this:

<body onunload=""><!-- This does the trick -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

You will see similar results when using JQuery.

You may want to compare to this one without onunload

<body><!-- Will not reload on back button -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

The reasonable way how to launch apps from HTML is through url schemes. So you can launch email via mailto: links and irc through irc: links. Individual apps can implement these schemes, but I'm not sure WinMerge does this.

Click with contextMenu button on Mysql prompt and choose "Scroll", because I didn't find any way to clean too. =P

One way to get this error in Eclipse :

1. Define a class A in src/test/java.
2. Define another class B in src/main/java that uses class A.

Result : Eclipse will compile the code, but maven will give "Cannot find symbol".

Underlying cause : Eclipse is using a combined build path for the main and test trees. Unfortunately, it does not support using different build paths for different parts of an Eclipse project, which is what Maven requires.

Solution :

1. Don't define your dependencies that way; i.e. don't make this mistake.
2. Regularly build your codebase using Maven so that you pick up this mistake early. One way to do that is to use a CI server.

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

Something like this:

var option = document.createElement("option");
option.text = "Text";
option.value = "myvalue";
var select = document.getElementById("id-to-my-select-box");
select.appendChild(option);

You can even use this one. worked well for me

$("#registerform").attr("action", "register.php?btnsubmit=Save") 
$('#registerform').submit();

this will submit btnsubmit =Save as GET value to register.php form.

With java 8 you can try this:

import org.json.JSONException;
import org.json.JSONObject;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class JSONUtil {

    public static JSONObject parseJSONFile(String filename) throws JSONException, IOException {
        String content = new String(Files.readAllBytes(Paths.get(filename)));
        return new JSONObject(content);
    }

    public static void main(String[] args) throws IOException, JSONException {
        String filename = "path/to/file/abc.json";
        JSONObject jsonObject = parseJSONFile(filename);

        //do anything you want with jsonObject
    }
}

You can convert Date to almost any format using the Snippet I have added below.

Code:

dateFormat(new Date(),"dd/mm/yy h:MM TT")
//"20/06/14 6:49 PM"

Other examples

// Can also be used as a standalone function
dateFormat(new Date(), "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM

dateFormat(new Date(),"dddd d mmmm yyyy")
//Monday 2 June 2014"

Snippet:

Add following code taken from this link into your code.

var dateFormat = function () {
    var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
        timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
        timezoneClip = /[^-+\dA-Z]/g,
        pad = function (val, len) {
            val = String(val);
            len = len || 2;
            while (val.length < len) val = "0" + val;
            return val;
        };

    // Regexes and supporting functions are cached through closure
    return function (date, mask, utc) {
        var dF = dateFormat;

        // You can't provide utc if you skip other args (use the "UTC:" mask prefix)
        if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
            mask = date;
            date = undefined;
        }

        // Passing date through Date applies Date.parse, if necessary
        date = date ? new Date(date) : new Date;
        if (isNaN(date)) throw SyntaxError("invalid date");

        mask = String(dF.masks[mask] || mask || dF.masks["default"]);

        // Allow setting the utc argument via the mask
        if (mask.slice(0, 4) == "UTC:") {
            mask = mask.slice(4);
            utc = true;
        }

        var _ = utc ? "getUTC" : "get",
            d = date[_ + "Date"](),
            D = date[_ + "Day"](),

There is now (Chrome 76+ & FF 69+) a Blob.prototype.arrayBuffer() method which will return a Promise resolving with an ArrayBuffer representing the Blob's data.

(async () => {_x000D_
  const blob = new Blob(['hello']);_x000D_
  const buf = await blob.arrayBuffer();_x000D_
  console.log( buf.byteLength ); // 5_x000D_
})();

Make children divs inline-block and they will position side by side:

#content {
   width: 500px;
   height: 500px;
}

#left, #right {
    display: inline-block;
    width: 45%;
    height: 100%;
}

No JS needed really ... Just add a type attribute to the button with a value of button

<Button type="button" color="primary" onClick={this.onTestClick}>primary</Button>&nbsp;

By default, button elements are of the type "submit" which causes them to submit their enclosing form element (if any). Changing the type to "button" prevents that.

it clears stdin buffer before reading. From the man page:

For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.

Note: This is Linux-specific, using fflush() on input streams is undefined by the standard, however, most implementations behave the same as in Linux.

#include "stdio.h"

void print_ip(int ip) {
   unsigned char bytes[4];
   int i;
   for(i=0; i<4; i++) {
      bytes[i] = (ip >> i*8) & 0xFF;
   }
   printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);
}

int main() {
   int ip = 0xDEADBEEF;
   print_ip(ip);   
}

This function returns the nth part of input string MYSTRING. Second input parameter is separator ie., SEPARATOR_OF_SUBSTR and the third parameter is Nth Part which is required.

Note: MYSTRING should end with the separator.

create or replace FUNCTION PK_GET_NTH_PART(MYSTRING VARCHAR2,SEPARATOR_OF_SUBSTR VARCHAR2,NTH_PART NUMBER)
RETURN VARCHAR2
IS
NTH_SUBSTR VARCHAR2(500);
POS1 NUMBER(4);
POS2 NUMBER(4);
BEGIN
IF NTH_PART=1 THEN
SELECT REGEXP_INSTR(MYSTRING,SEPARATOR_OF_SUBSTR, 1, 1)  INTO POS1 FROM DUAL; 
SELECT SUBSTR(MYSTRING,0,POS1-1) INTO NTH_SUBSTR FROM DUAL;
ELSE
SELECT REGEXP_INSTR(MYSTRING,SEPARATOR_OF_SUBSTR, 1, NTH_PART-1) INTO  POS1 FROM DUAL; 
SELECT REGEXP_INSTR(MYSTRING,SEPARATOR_OF_SUBSTR, 1, NTH_PART)  INTO POS2 FROM DUAL; 
SELECT SUBSTR(MYSTRING,POS1+1,(POS2-POS1-1)) INTO NTH_SUBSTR FROM DUAL;
END IF;
RETURN NTH_SUBSTR;
END;

Hope this helps some body, you can use this function like this in a loop to get all the values separated:

SELECT REGEXP_COUNT(MYSTRING, '~', 1, 'i') INTO NO_OF_RECORDS FROM DUAL;
WHILE NO_OF_RECORDS>0
LOOP
    PK_RECORD    :=PK_GET_NTH_PART(MYSTRING,'~',NO_OF_RECORDS);
    -- do some thing
    NO_OF_RECORDS  :=NO_OF_RECORDS-1;
END LOOP;

Here NO_OF_RECORDS,PK_RECORD are temp variables.

Hope this helps.

You can also use the good old micro clearfix for this.

    content: ' ';
    display: table;
}

location.hash is not safe for IE , in case of IE ( including IE9 ) , if your page contains iframe , then after manual refresh inside iframe content get location.hash value is old( value for first page load ). while manual retrieved value is different than location.hash so always retrieve it through document.URL

var hash = document.URL.substr(document.URL.indexOf('#')+1) 

Add MultipleActiveResultSets=true to the provider part of your connection string example in the file appsettings.json

"ConnectionStrings": {
"EmployeeDBConnection": "server=(localdb)\\MSSQLLocalDB;database=YourDatabasename;Trusted_Connection=true;MultipleActiveResultSets=true"}

Both commands are correct

php_value post_max_size 30M 

php_value upload_max_filesize 30M 

BUT to use the .htaccess you have to enable rewrite_module in Apache config file. In httpd.conf find this line:

# LoadModule rewrite_module modules/mod_rewrite.so

and remove the #.

Reference Resolution is described by RFC 3986 Uniform Resource Identifier (URI): Generic Syntax. And that is exactly how it supposed to work. To preserve base URI path you need to add slash at the end of the base URI and remove slash at the beginning of relative URI.

If base URI contains non-empty path, merge procedure discards it's last part (after last /). Relevant section:

5.2.3. Merge Paths

The pseudocode above refers to a "merge" routine for merging a relative-path reference with the path of the base URI. This is accomplished as follows:

• If the base URI has a defined authority component and an empty path, then return a string consisting of "/" concatenated with the reference's path; otherwise

• return a string consisting of the reference's path component appended to all but the last segment of the base URI's path (i.e., excluding any characters after the right-most "/" in the base URI path, or excluding the entire base URI path if it does not contain any "/" characters).

If relative URI starts with a slash, it is called a absolute-path relative URI. In this case merge procedure ignore all base URI path. For more information check 5.2.2. Transform References section.

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

Solution 1: You can declare .modal{ overflow-y:auto} or .modal-open .modal{ overflow-y:auto} if you are using below 3v of bootstrap (for upper versions it is already declared).

Bootstrap adds modal-open class to body in order to remove scrollbars in case modal is shown, but does not add any class to html which also can have scrollbars, as a result the scrollbar of html sometimes can be visible too, to remove it you have to set modal show/hide events and add/remove overflow:hidden on html. Here how to do this.

$('.modal').on('hidden.bs.modal', function () {
   $('html').css('overflow','auto');
}).on('shown.bs.modal', function () {
   $('html').css('overflow','hidden');
});

Solution 2: As modal has functionality keys, the best way to handle this is to fix height of or even better connect the height of modal with height of the viewport like this -

.modal-body {
     overflow:auto; 
     max-height: 65vh;
}

With this method you also do not have to handle body and html scrollbars.

Note 1: Browser support for vh units.

Note 2: As it is proposed above. If you change .modal{position:fixed} to .modal{position:absolute}, but in case page has more height than modal user can scroll too much up and modal will disappear from viewport, this is not good for user experience.

Add this two file in res/anim folder.

R.anim.slide_out_bottom

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
    android:duration="@integer/time_duration_max"
    android:fromXDelta="0%"
    android:fromYDelta="100%"
    android:toXDelta="0%"
    android:toYDelta="0%" />
</set>

R.anim.slide_in_bottom

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
    android:duration="@integer/time_duration_max"
    android:fromXDelta="0%"
    android:fromYDelta="0%"
    android:toXDelta="0%"
    android:toYDelta="100%" /> 
</set>

And write the below line of code in your view click listener.

startActivity(new Intent(MainActivity.this, NameOfTargetActivity.class));
overridePendingTransition(R.anim.slide_out_bottom, R.anim.slide_in_bottom);

<html>

<script language="javascript" type="text/javascript">
var scrt_var = 10; 
openPage = function() {
location.href = "2.html?Key="+scrt_var;
}
</script>

 this is a <a href ="javascript:openPage()">Link  </a>
</html>

In addition to the accepted answer, there is a corner case when you should use filter instead of a list comprehension. If the list is unhashable you cannot directly process it with a list comprehension. A real world example is if you use pyodbc to read results from a database. The fetchAll() results from cursor is an unhashable list. In this situation, to directly manipulating on the returned results, filter should be used:

cursor.execute("SELECT * FROM TABLE1;")
data_from_db = cursor.fetchall()
processed_data = filter(lambda s: 'abc' in s.field1 or s.StartTime >= start_date_time, data_from_db) 

If you use list comprehension here you will get the error:

TypeError: unhashable type: 'list'

I have merged some solutions to make a complete util for picking an image from Gallery or Camera. These are the features of ImagePicker util (also in a Github lib):

• Merged intents for Gallery and Camera resquests.
• Resize selected big images (e.g.: 2500 x 1600)
• Rotate image if necesary

Screenshot:

Edit: Here is a fragment of code to get a merged Intent for Gallery and Camera apps together. You can see the full code at ImagePicker util (also in a Github lib):

public static Intent getPickImageIntent(Context context) {
    Intent chooserIntent = null;

    List<Intent> intentList = new ArrayList<>();

    Intent pickIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    takePhotoIntent.putExtra("return-data", true);
    takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(context)));
    intentList = addIntentsToList(context, intentList, pickIntent);
    intentList = addIntentsToList(context, intentList, takePhotoIntent);

    if (intentList.size() > 0) {
        chooserIntent = Intent.createChooser(intentList.remove(intentList.size() - 1),
                context.getString(R.string.pick_image_intent_text));
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new Parcelable[]{}));
    }

    return chooserIntent;
}

private static List<Intent> addIntentsToList(Context context, List<Intent> list, Intent intent) {
    List<ResolveInfo> resInfo = context.getPackageManager().queryIntentActivities(intent, 0);
    for (ResolveInfo resolveInfo : resInfo) {
        String packageName = resolveInfo.activityInfo.packageName;
        Intent targetedIntent = new Intent(intent);
        targetedIntent.setPackage(packageName);
        list.add(targetedIntent);
    }
    return list;
}

Yes, they are different...

# is an id selector, used to target a single specific element with a unique id, but . is a class selector used to target multiple elements with a particular class. To put it another way:

• #foo {} will style the single element declared with an attribute id="foo"
• .foo {} will style all elements with an attribute class="foo" (you can have multiple classes assigned to an element too, just separate them with spaces, e.g. class="foo bar")

Typical uses

Generally speaking, you use # for styling something you know is only going to appear once, for example, things like high level layout divs such sidebars, banner areas etc.

Classes are used where the style is repeated, e.g. say you head a special form of header for error messages, you could create a style h1.error {} which would only apply to <h1 class="error">

Specificity

Another aspect where selectors differ is in their specificity - an id selector is deemed to be more specific than class selector. This means that where styles conflict on an element, the ones defined with the more specific selector will override less specific selectors. For example, given <div id="sidebar" class="box"> any rules for #sidebar with override conflicting rules for .box

Learn more about CSS selectors

See Selectutorial for more great primers on CSS selectors - they are incredibly powerful, and if your conception is simply that "# is used for DIVs" you'd do well to read up on exactly how to use CSS more effectively.

EDIT: Looks like Selectutorial might have gone to the big website in the sky, so try this archive link instead.

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

git remote show origin -n | ruby -ne 'puts /^\s*Fetch.*(:|\/){1}([^\/]+\/[^\/]+).git/.match($_)[2] rescue nil'

It was tested with three different URL styles:

echo "Fetch URL: http://user@pass:gitservice.org:20080/owner/repo.git" | ruby -ne 'puts /^\s*Fetch.*(:|\/){1}([^\/]+\/[^\/]+).git/.match($_)[2] rescue nil'
echo "Fetch URL: Fetch URL: [email protected]:home1-oss/oss-build.git" | ruby -ne 'puts /^\s*Fetch.*(:|\/){1}([^\/]+\/[^\/]+).git/.match($_)[2] rescue nil'
echo "Fetch URL: https://github.com/owner/repo.git" | ruby -ne 'puts /^\s*Fetch.*(:|\/){1}([^\/]+\/[^\/]+).git/.match($_)[2] rescue nil'

I just ran into this problem myself.

First, modify your code slightly:

var download = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                  +"<"+this.gamesave.tagName+">"
                  +this.xml.firstChild.innerHTML
                  +"</"+this.gamesave.tagName+">";

this.loader.src = "data:application/x-forcedownload;base64,"+
                  btoa(download);

Then use your favorite web inspector, put a breakpoint on the line of code that assigns this.loader.src, then execute this code:

for (var i = 0; i < download.length; i++) {
  if (download[i].charCodeAt(0) > 255) {
    console.warn('found character ' + download[i].charCodeAt(0) + ' "' + download[i] + '" at position ' + i);
  }
}

Depending on your application, replacing the characters that are out of range may or may not work, since you'll be modifying the data. See the note on MDN about unicode characters with the btoa method:

https://developer.mozilla.org/en-US/docs/Web/API/window.btoa
