If you only want to match "" as an empty string

WHERE DATALENGTH(COLUMN) > 0 

If you want to count any string consisting entirely of spaces as empty

WHERE COLUMN <> '' 

Both of these will not return NULL values when used in a WHERE clause. As NULL will evaluate as UNKNOWN for these rather than TRUE.

CREATE TABLE T 
  ( 
     C VARCHAR(10) 
  ); 

INSERT INTO T 
VALUES      ('A'), 
            (''),
            ('    '), 
            (NULL); 

SELECT * 
FROM   T 
WHERE  C <> ''

Returns just the single row A. I.e. The rows with NULL or an empty string or a string consisting entirely of spaces are all excluded by this query.

You can use the lower function:

Guide.where("lower(title)='attack'")

I found that the problem is that I only have a production environment. I do not have a development or test environment.

By adding 'RAILS_ENV=production' to give the command

bundle exec rake redmine:plugins:migrate RAILS_ENV=production

it worked

You can leverage the streams API of Java 8.

public class ListToMap {

  public static void main(String[] args) {
    List<User> items = Arrays.asList(new User("One"), new User("Two"), new User("Three"));

    Map<String, User> map = createHashMap(items);
    for(String key : map.keySet()) {
      System.out.println(key +" : "+map.get(key));
    }
  }

  public static Map<String, User> createHashMap(List<User> items) {
    Map<String, User> map = items.stream().collect(Collectors.toMap(User::getId, Function.identity()));
    return map;
  }
}

See section Attributes from documentation on directives.

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

Edit: The bitset stuff below is maybe an interesting read, but the answer itself is a bit dated. Some of this functionality is changing around in 2.x. Also Slawek points out in another answer that the terms query is an easy way to DRY up the search in this case. Refactored at the end for current best practices. —nz

You'll probably want a Bool Query (or more likely Filter alongside another query), with a should clause.

The bool query has three main properties: must, should, and must_not. Each of these accepts another query, or array of queries. The clause names are fairly self-explanatory; in your case, the should clause may specify a list filters, a match against any one of which will return the document you're looking for.

From the docs:

In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

Here's an example of what that Bool query might look like in isolation:

{
  "bool": {
    "should": [
      { "term": { "tag": "c" }},
      { "term": { "tag": "d" }}
    ]
  }
}

And here's another example of that Bool query as a filter within a more general-purpose Filtered Query:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "bool": {
        "should": [
          { "term": { "tag": "c" }},
          { "term": { "tag": "d" }}
        ]
      }
    }
  }
}

Whether you use Bool as a query (e.g., to influence the score of matches), or as a filter (e.g., to reduce the hits that are then being scored or post-filtered) is subjective, depending on your requirements.

It is generally preferable to use Bool in favor of an Or Filter, unless you have a reason to use And/Or/Not (such reasons do exist). The Elasticsearch blog has more information about the different implementations of each, and good examples of when you might prefer Bool over And/Or/Not, and vice-versa.

Elasticsearch blog: All About Elasticsearch Filter Bitsets

Update with a refactored query...

Now, with all of that out of the way, the terms query is a DRYer version of all of the above. It does the right thing with respect to the type of query under the hood, it behaves the same as the bool + should using the minimum_should_match options, and overall is a bit more terse.

Here's that last query refactored a bit:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "terms": {
        "tag": [ "c", "d" ],
        "minimum_should_match": 1
      }
    }
  }
}

@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.

These days you can also use the Web API ResizeObserver.

Simple example:

const resizeObserver = new ResizeObserver(() => {
    console.log('size changed');
});

resizeObserver.observe(document.querySelector('#myElement'));

The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0^{[Ref 1]}.
The second is more readable.

The choice depends on user preference or the one which your coding standard mandates.

^{[Ref 1]} Reference C99 Standard 6.7.8.21:

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

NVL(length(clob_col_name),0) works for me.

Simply use the separator image as a background image on the li.

To get it to only appear in between list items, position the image to the left of the li, but not on the first one.

For example:

#nav li + li {
    background:url('seperator.gif') no-repeat top left;
    padding-left: 10px
}

This CSS adds the image to every list item that follows another list item - in other words all of them but the first.

NB. Be aware the adjacent selector (li + li) doesn't work in IE6, so you will have to just add the background image to the conventional li (with a conditional stylesheet) and perhaps apply a negative margin to one of the edges.

Please <staticContent /> line and erased it from the web.config.

I know this has already been highly voted in here by now, but I'd rather go for a custom directive approach and rely on the ClipboardEvent as @jockeisorby suggested, while also making sure the listener is correctly removed (same function needs to be provided for both the add and remove event listeners)

stackblitz demo

import { Directive, Input, Output, EventEmitter, HostListener } from "@angular/core";

@Directive({ selector: '[copy-clipboard]' })
export class CopyClipboardDirective {

  @Input("copy-clipboard")
  public payload: string;

  @Output("copied")
  public copied: EventEmitter<string> = new EventEmitter<string>();

  @HostListener("click", ["$event"])
  public onClick(event: MouseEvent): void {

    event.preventDefault();
    if (!this.payload)
      return;

    let listener = (e: ClipboardEvent) => {
      let clipboard = e.clipboardData || window["clipboardData"];
      clipboard.setData("text", this.payload.toString());
      e.preventDefault();

      this.copied.emit(this.payload);
    };

    document.addEventListener("copy", listener, false)
    document.execCommand("copy");
    document.removeEventListener("copy", listener, false);
  }
}

and then use it as such

<a role="button" [copy-clipboard]="'some stuff'" (copied)="notify($event)">
  <i class="fa fa-clipboard"></i>
  Copy
</a>

public notify(payload: string) {
   // Might want to notify the user that something has been pushed to the clipboard
   console.info(`'${payload}' has been copied to clipboard`);
}

Note: notice the window["clipboardData"] is needed for IE as it does not understand e.clipboardData

I encountered this error where

• two methods, A & B, in a single controller both used the same instance of an ApplicationDbContext, and
• method A called method B

    private ApplicationDbContext db;
    // api methods
    public JsonResult methodA(string id){
        Resource resource = db.Resources.Find(id);
        db.Entry(resource).State = EntityState.Modified;
        db.SaveChanges();
        return methodB()
    }

    public JsonResult methodB(string id){
        Resource resource = db.Resources.Find(id);
        db.Entry(resource).State = EntityState.Modified;
        db.SaveChanges();
        return new JsonResult();
    }

I changed method B to have a using statement and rely only on the local db2. After:

    private ApplicationDbContext db;    
    // api methods    
    public JsonResult methodA(string id){
        Resource resource = db.Resources.Find(id);
        db.Entry(resource).State = EntityState.Modified;
        db.SaveChanges();
        return methodB()
    }

    public JsonResult methodB(string id){
        using (var db2 = new ApplicationDbContext())
        {
            Resource resource = db2.Resources.Find(id);
            db2.Entry(resource).State = EntityState.Modified;
            db2.SaveChanges();
        }
        return new JsonResult();
    }

When none of the if test in number_translator() evaluate to true, the function returns None. The error message is the consequence of that.

Whenever you see an error that include 'NoneType' that means that you have an operand or an object that is None when you were expecting something else.

I could use the GetBody from Request package.

Look this comment in source code from request.go in net/http:

GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."

GetBody func() (io.ReadCloser, error)

This way you can get the body request without make it empty.

Sample:

getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
    // Do something return err
}
http.DefaultClient.Do(request)

All you need to give the name attribute to the each button. And you need to address each button press from the PHP script. But be careful to give each button a unique name. Because the PHP script only take care of the name most of the time

<input type="submit" name="Submit_this" id="This" />

The get method of a dict (like for example characters) works just like indexing the dict, except that, if the key is missing, instead of raising a KeyError it returns the default value (if you call .get with just one argument, the key, the default value is None).

So an equivalent Python function (where calling myget(d, k, v) is just like d.get(k, v) might be:

def myget(d, k, v=None):
  try: return d[k]
  except KeyError: return v

The sample code in your question is clearly trying to count the number of occurrences of each character: if it already has a count for a given character, get returns it (so it's just incremented by one), else get returns 0 (so the incrementing correctly gives 1 at a character's first occurrence in the string).

private bool CheckAll()
{
    if ( ....)
    {
        return true;
    }

    return false;
}

When the if-condition is false the method doesn't know what value should be returned (you probably get an error like "not all paths return a value").

As CQQL pointed out if you mean to return true when your if-condition is true you could have simply written:

private bool CheckAll()
{
    return (your_condition);
}

If you have side effects, and you want to handle them before you return, the first (long) version would be required.

Edit: Warning! This answer worked on my XAMPP OsX environment, but when I deployed it to AWS EC2 it did NOT prevent the upload attempt.

I was tempted to delete this answer as it is WRONG But instead I will explain what tripped me up

My file upload field is named 'upload' so I was getting "The upload failed to upload.". This message comes from this line in validation.php:

in resources/lang/en/validaton.php:

'uploaded' => 'The :attribute failed to upload.',

And this is the message displayed when the file is larger than the limit set by PHP.

I want to over-ride this message, which you normally can do by passing a third parameter $messages array to Validator::make() method.

However I can't do that as I am calling the POST from a React Component, which renders the form containing the csrf field and the upload field.

So instead, as a super-dodgy-hack, I chose to get into my view that displays the messages and replace that specific message with my friendly 'file too large' message.

Here is what works if the file to smaller than the PHP file size limit:

In case anyone else is using Laravel FormRequest class, here is what worked for me on Laravel 5.7:

This is how I set a custom error message and maximum file size:

I have an input field <input type="file" name="upload">. Note the CSRF token is required also in the form (google laravel csrf_field for what this means).

<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class Upload extends FormRequest
{
  ...
  ...
  public function rules() {
    return [
      'upload' => 'required|file|max:8192',
    ];
  }
  public function messages()
  {
    return [            
      'upload.required' => "You must use the 'Choose file' button to select which file you wish to upload",
      'upload.max' => "Maximum file size to upload is 8MB (8192 KB). If you are uploading a photo, try to reduce its resolution to make it under 8MB"
    ];
  }
}

A useful trick to avoid creating temporary patch files:

git diff | patch -p1 -d [dst-dir]

Asterisk symbol (*) is used to check values in the array, not the array itself.

$validator = Validator::make($request->all(), [
    "names"    => "required|array|min:3",
    "names.*"  => "required|string|distinct|min:3",
]);

In the example above:

• "names" must be an array with at least 3 elements,
• values in the "names" array must be distinct (unique) strings, at least 3 characters long.

EDIT: Since Laravel 5.5 you can call validate() method directly on Request object like so:

$data = $request->validate([
    "name"    => "required|array|min:3",
    "name.*"  => "required|string|distinct|min:3",
]);

In 9.4.4 using the #>> operator works for me:

select to_json('test'::text) #>> '{}';

To use with a table column:

select jsoncol #>> '{}' from mytable;

To remove some key value pair form object array uses Postgres SQL as database like this example:

This is user function return user details object, we have to remove "api_secret" key from rows :

    function getCurrentUser(req, res, next) { // user function
    var userId = res.locals.userId;
    console.log(userId)
    db.runSQLWithParams("select * from users where id = $1", [userId], function(err, rows) {
      if(err){
        console.log(err)
      }
      var responseObject = {
        _embedded: rows,
      }
      responseObject._embedded[0].api_secret = undefined
      // console.log(api);
      // console.log(responseObject);
      res.json(responseObject);
    }); 
}

The above function return below object as JSON response before

 {
    "_embedded": [
        {
            "id": "0123abd-345gfhgjf-dajd4456kkdj",
            "secret_key: "secret",
            "email": "[email protected]",
            "created": "2020-08-18T00:13:16.077Z"
        }
    ]
}

After adding this line responseObject._embedded[0].api_secret = undefined It gives below result as JSON response:

{
        "_embedded": [
            {
                "id": "0123abd-345gfhgjf-dajd4456kkdj",
                "email": "[email protected]",
                "created": "2020-08-18T00:13:16.077Z"
            }
        ]
    }

Follow the screenshot below. It works when you run the simulator (won't see it on preview)

Easy way to fix this issue, try this

systemctl start docker
systemctl enable docker
systemctl restart docker

We can make class dynamic by using following syntax. In Angular 2 plus, you can do this in various ways:

[ngClass]="{'active': arrayData.length && arrayData[0]?.booleanProperty}"

[ngClass]="{'active': step}"

[ngClass]="step== 'step1'?'active':''"

[ngClass]="step? 'active' : ''"

I'll just leave this here for people interested in an implementation with no dependencies.

inline int
stringLength (char *String)
    {
    int Count = 0;
    while (*String ++) ++ Count;
    return Count;
    }

inline int
stringToInt (char *String)
    {
    int Integer = 0;
    int Length = stringLength(String);
    for (int Caret = Length - 1, Digit = 1; Caret >= 0; -- Caret, Digit *= 10)
        {
        if (String[Caret] == '-') return Integer * -1;
        Integer += (String[Caret] - '0') * Digit;
        }

    return Integer;
    }

Works with negative values, but can't handle non-numeric characters mixed in between (should be easy to add though). Integers only.

I also face that problem Finally, i solved it

<meta property="og:image" itemprop="image" content="http://yourdomain.com/yourfolder/imagename.png" />

My image property

1. Dimension : 300X200
2. Size : < 300KB
3. URL: http://yourdomain.com/yourfolder/imagename.png

Make sure in image name there is no space, if you have two words then use underscore sign

You have to rename Organization Identifier on Bundle Identifier on settings tab.

Only by renaming the Organization Identifier error will remove.

Can you try this,

var ajaxSubmit = function(formE1) {

            var password = $.trim($('#employee_password').val());

             $.ajax({
                type: "POST",
                async: "false",
                url: "checkpass.php",
                data: "password="+password,
                success: function(html) {
                    var arr=$.parseJSON(html);
                    if(arr == "Successful")
                    { 
                         **$("form[name='form']").submit();**
                        return true;
                    }
                    else
                    {    return false;
                    }
                }
            });
              **return false;**
        }

Try

String query = "INSERT INTO dbo.SMS_PW (id,username,password,email) VALUES (@id,@username, @password, @email)";
using(SqlConnection connection = new SqlConnection(connectionString))
using(SqlCommand command = new SqlCommand(query, connection))
{
    //a shorter syntax to adding parameters
    command.Parameters.Add("@id", SqlDbType.NChar).Value = "abc";

    command.Parameters.Add("@username", SqlDbType.NChar).Value = "abc";

    //a longer syntax for adding parameters
    command.Parameters.Add("@password", SqlDbType.NChar).Value = "abc";

    command.Parameters.Add("@email", SqlDbType.NChar).Value = "abc";

    //make sure you open and close(after executing) the connection
    connection.Open();
    command.ExecuteNonQuery();
}

I have done a very simple thing to enable or disable command button. Below is my grid

        if (e.Row.RowType == DataControlRowType.DataRow)
        {                

                foreach (ImageButton button in e.Row.Cells[5].Controls.OfType<ImageButton>())
                {
                    if (button.CommandName == "Delete")
                    {
                        button.Visible = false;
                    }
                }                    

        }
    }

Look how I format my date $jour in the parameters. It depends if you use a expr()->like or a expr()->lte

$qb
        ->select('e')
        ->from('LdbPlanningBundle:EventEntity', 'e')
        ->where(
            $qb->expr()->andX(
                $qb->expr()->orX(
                    $qb->expr()->like('e.start', ':jour1'),
                    $qb->expr()->like('e.end', ':jour1'),
                    $qb->expr()->andX(
                        $qb->expr()->lte('e.start', ':jour2'),
                        $qb->expr()->gte('e.end', ':jour2')
                    )
                ),
                $qb->expr()->eq('e.user', ':user')
            )
        )
        ->andWhere('e.user = :user ')
        ->setParameter('user', $user)
        ->setParameter('jour1', '%'.$jour->format('Y-m-d').'%')
        ->setParameter('jour2', $jour->format('Y-m-d'))
        ->getQuery()
        ->getArrayResult()
    ;

It's not called a tag; what you're looking for is called an html attribute.

$('div[imageId="imageN"]').each(function(i,el){
  $(el).html('changes');
  //do what ever you wish to this object :) 
});

More points regarding File Descriptor:

1. File Descriptors (FD) are non-negative integers (0, 1, 2, ...) that are associated with files that are opened.

2. 0, 1, 2 are standard FD's that corresponds to STDIN_FILENO, STDOUT_FILENO and STDERR_FILENO (defined in unistd.h) opened by default on behalf of shell when the program starts.

3. FD's are allocated in the sequential order, meaning the lowest possible unallocated integer value.

4. FD's for a particular process can be seen in /proc/$pid/fd (on Unix based systems).

To install 3.0 which is the latest stable version:

$ git clone http://github.com/antirez/redis.git 
$ cd redis && git checkout 3.0 
$ make redis-cli 

Optionally, you can put the compiled executable in your load path for convenience:

$ ln -s src/redis-cli /usr/local/bin/redis-cli

You really should use an established library, such as Newtonsoft.Json (which even Microsoft uses for frameworks such as MVC and WebAPI), or .NET's built-in JavascriptSerializer.

Here's a sample of reading JSON using Newtonsoft.Json:

JObject o1 = JObject.Parse(File.ReadAllText(@"c:\videogames.json"));

// read JSON directly from a file
using (StreamReader file = File.OpenText(@"c:\videogames.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
  JObject o2 = (JObject) JToken.ReadFrom(reader);
}

In my case the SDKROOT environment variable was wrong, which referred to an old version of iPhoneOSxx.x.sdk. (Perhaps this would have automatically resolved itself after a reboot?)

You can check by running echo $SDKROOT and verifying that it's a valid path.

I fixed it by updating in .bash_profile:

export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.2.sdk

There you go:

timeout --signal=SIGINT 10 /path/to/slow command with options

you may change the SIGINT and 10 as you desire ;)

Easiest way

The most trivial way to upload a file to an FTP server using .NET framework is using WebClient.UploadFile method:

WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");

Advanced options

If you need a greater control, that WebClient does not offer (like TLS/SSL encryption, ascii/text transfer mode, active mode, transfer resuming, progress monitoring, etc), use FtpWebRequest. Easy way is to just copy a FileStream to an FTP stream using Stream.CopyTo:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;  

using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
using (Stream ftpStream = request.GetRequestStream())
{
    fileStream.CopyTo(ftpStream);
}

Progress monitoring

If you need to monitor an upload progress, you have to copy the contents by chunks yourself:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;  

using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
using (Stream ftpStream = request.GetRequestStream())
{
    byte[] buffer = new byte[10240];
    int read;
    while ((read = fileStream.Read(buffer, 0, buffer.Length)) > 0)
    {
        ftpStream.Write(buffer, 0, read);
        Console.WriteLine("Uploaded {0} bytes", fileStream.Position);
    } 
}

For GUI progress (WinForms ProgressBar), see C# example at:
How can we show progress bar for upload with FtpWebRequest

Uploading folder

If you want to upload all files from a folder, see
Upload directory of files to FTP server using WebClient.

For a recursive upload, see
Recursive upload to FTP server in C#

.remove() is deprecated. instead we can use deleteMany

DateTime.deleteMany({}, callback).

For my case, dmatrices in patsy solved my problem. Actually, this function is designed for the generation of dependent and independent variables from a given DataFrame with an R-style formula string. But it can be used for the generation of dummy features from the categorical features. All you need to do would be drop the column 'Intercept' that is generated by dmatrices automatically regardless of your original DataFrame.

import pandas as pd
from patsy import dmatrices

df_original = pd.DataFrame({
   'A': ['red', 'green', 'red', 'green'],
   'B': ['car', 'car', 'truck', 'truck'],
   'C': [10,11,12,13],
   'D': ['alice', 'bob', 'charlie', 'alice']},
   index=[0, 1, 2, 3])

_, df_dummyfied = dmatrices('A ~ A + B + C + D', data=df_original, return_type='dataframe')
df_dummyfied = df_dummyfied.drop('Intercept', axis=1)

df_dummyfied.columns    
Index([u'A[T.red]', u'B[T.truck]', u'D[T.bob]', u'D[T.charlie]', u'C'], dtype='object')

df_dummyfied
   A[T.red]  B[T.truck]  D[T.bob]  D[T.charlie]     C
0       1.0         0.0       0.0           0.0  10.0
1       0.0         0.0       1.0           0.0  11.0
2       1.0         1.0       0.0           1.0  12.0
3       0.0         1.0       0.0           0.0  13.0

First

ps -ef

to list all processes. Note the the process number of the one you want to kill. Then

kill 1234

were you replace 1234 with the process number that you want.

Alternatively, if you are absolutely certain that there is only one process with a particular name, or you want to kill multiple processes which share the same name

killall processname

I think that Microsoft can fix this ambiguity by making the compiler add runat attribute before the page is ever compiled, something like the type-erasure thing that java has with the generics, instead of erasing, it could be writing runat=server wherever it sees asp: prefix for tags, so the developer would not need to worry about it.

Basically, the problem lies in block12. for the block1/2 to take up the total height of the block12, it must have a defined height. This stack overflow post explains that in really good detail.

So setting a defined height for block12 will allow you to set a proper height. I have created an example on JSfiddle that will show you the the blocks can be floated next to one another if the block12 div is set to a standard height through out the page.

Here is an example including a header and block3 div with some content in for examples.

#header{
   position:absolute;
   top:0;
   left:0;
   width:100%;
   height:20%;
    }

    #block12{
    position:absolute;
    top:20%;
    width:100%;
    left:0;
    height:40%;
    }
    #block1,#block2{
    float:left;
    overflow-y: scroll;
    text-align:center;
    color:red;
    width:50%;
    height:100%;

    }
 #clear{clear:both;}
 #block3{
    position:absolute;
    bottom:0;
    color:blue;
    height:40%;

    }

Starting from iOS 7, the system always returns the value 02:00:00:00:00:00 when you ask for the MAC address on any device.

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)"

Abstract classes cannot be instantiated, but they can be subclassed. See This Link

The best example is

Although Calender class has a abstract method getInstance(), but when you say Calendar calc=Calendar.getInstance();

calc is referring to the class instance of class GregorianCalendar as "GregorianCalendar extends Calendar "

Infact annonymous inner type allows you to create a no-name subclass of the abstract class and an instance of this.

I believe this line in the web.config will set the max upload size:

<system.web>

        <httpRuntime maxRequestLength="600000"/>
</system.web>

Same thing with gcc version 4.8.1 (GCC) and libstdc++.so.6.0.18. Had to copy it here /usr/lib/x86_64-linux-gnu on my ubuntu box.

The most easy way, with direct access to the machine is to copy the job folder from first jenkins to another one (you can exclude workspaces - workspace folder), because the whole job configuration is stored in the xml file on the disk.

Then in the new jenkins just reload configuration in the global settings (admin access is required) should be enough, if not, then you will need to restart Jenkins tool.

Another way can be to use plugins mentioned above this post.

edit: - in case you can probably also exclude modules folders

It looks like derivedFactor from the mosaic package was designed for this. In this example, it would look something like:

library(mosaic)
myfile <- mutate(myfile, V5 = derivedFactor(
    "1" = (V1==1 & V2!=4),
    "2" = (V2==4 & V3!=1),
    .method = "first",
    .default = 0
    ))

(If you want the outcome to be numeric instead of a factor, wrap the derivedFactor with an as.numeric.)

Note that the .default option combined with .method = "first" sets the "else" condition -- this approach is described in the help file for derivedFactor.

You can also use the summary for linear models:

summary(lm(obs ~ mod, data=df))$r.squared 

The be-all-end-all, for no selecting or dragging, with all browser prefixes:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
-ms-user-select: none;
user-select: none;

-webkit-user-drag: none;
-khtml-user-drag: none;
-moz-user-drag: none;
-o-user-drag: none;
-ms-user-drag: none;
user-drag: none;

You can also set the draggable attribute to false. You can do this with inline HTML: draggable="false", with Javascript: elm.draggable = false, or with jQuery: elm.attr('draggable', false).

You can also handle the onmousedown function to return false. You can do this with inline HTML: onmousedown="return false", with Javascript: elm.onmousedown=()=>return false;, or with jQuery: elm.mousedown(()=>return false)

When building TensorFlow from source, you'll run the configure script. One of the questions that the configure script asks is as follows:

Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]

The configure script will attach the flag(s) you specify to the bazel command that builds the TensorFlow pip package. Broadly speaking, you can respond to this prompt in one of two ways:

• If you are building TensorFlow on the same type of CPU type as the one on which you'll run TensorFlow, then you should accept the default (-march=native). This option will optimize the generated code for your machine's CPU type.
• If you are building TensorFlow on one CPU type but will run TensorFlow on a different CPU type, then consider supplying a more specific optimization flag as described in the gcc documentation.

After configuring TensorFlow as described in the preceding bulleted list, you should be able to build TensorFlow fully optimized for the target CPU just by adding the --config=opt flag to any bazel command you are running.

The answers on this question are not only wrong, but dangerous. CTRL+ALT+SHIFT+B will not indent HTML but XML. Consider the following HTML code:

<span class="myClass"></span>

The function 'Notepad++ -> Plugins -> XmlTools -> Pretty print (Xml only with line breaks)' (CTRL+ALT+SHIFT+B) will transform this to:

<span class="myClass"/>

which will not be displayed correctly anymore by your browser! I strongly advice against using this function to indent HTML.

Instead use the plugin Tidy2. This will indent the HTML correctly without bad side-effects (but it will also create <html>, <head>, <body>, ... elements around your code, if these are not there).

Use declare

There is no need on using prefixes like on other answers, neither arrays. Use just declare, double quotes, and parameter expansion.

I often use the following trick to parse argument lists contanining one to n arguments formatted as key=value otherkey=othervalue etc=etc, Like:

# brace expansion just to exemplify
for variable in {one=foo,two=bar,ninja=tip}
do
  declare "${variable%=*}=${variable#*=}"
done
echo $one $two $ninja 
# foo bar tip

But expanding the argv list like

for v in "$@"; do declare "${v%=*}=${v#*=}"; done

Extra tips

# parse argv's leading key=value parameters
for v in "$@"; do
  case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
done
# consume argv's leading key=value parameters
while (( $# )); do
  case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
  shift
done

The solution:

error : The requested URL returned error : 503 while Accessing

The error might be resolved by deleting the existing git folder.

I have used TestNG and Apache HTTP classes to build my own REST API test framework, I developed this concept after working in Selenium for two years.

Everything is same, except you should use Apache HTTP classes instead of Selenium classes.

give a try, its really cute and good, you've all the power to customize your test framework to your fullest possibilities.

REST stands for Representational state transfer.

It relies on a stateless, client-server, cacheable communications protocol -- and in virtually all cases, the HTTP protocol is used.

REST is often used in mobile applications, social networking Web sites, mashup tools and automated business processes. The REST style emphasizes that interactions between clients and services is enhanced by having a limited number of operations (verbs). Flexibility is provided by assigning resources (nouns) their own unique universal resource indicators (URIs).

Introduction about Rest

Use this simple code for DataTables custom sorting. Its 100% work

<script>
    $(document).ready(function() {
        $('#myTable').DataTable( {
            "order": [[ 0, "desc" ]] // "0" means First column and "desc" is order type; 
        } );
    } );
</script>

See in Datatables website

https://datatables.net/examples/basic_init/table_sorting.html

MM/DD/YYYY format

If you have the MM/DD/YYYY format which is default for JavaScript, you can simply pass your string to Date(string) constructor. It will parse it for you.

var dateString = "10/23/2015"; // Oct 23_x000D_
_x000D_
var dateObject = new Date(dateString);_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

DD/MM/YYYY format - manually

If you work with this format, then you can split the date in order to get day, month and year separately and then use it in another constructor - Date(year, month, day):

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateParts = dateString.split("/");_x000D_
_x000D_
// month is 0-based, that's why we need dataParts[1] - 1_x000D_
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]); _x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

For more information, you can read article about Date at Mozilla Developer Network.

DD/MM/YYYY - using moment.js library

Alternatively, you can use moment.js library, which is probably the most popular library to parse and operate with date and time in JavaScript:

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateMomentObject = moment(dateString, "DD/MM/YYYY"); // 1st argument - string, 2nd argument - format_x000D_
var dateObject = dateMomentObject.toDate(); // convert moment.js object to Date object_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

<script src="https://momentjs.com/downloads/moment.min.js"></script>

In all three examples dateObject variable contains an object of type Date, which represents a moment in time and can be further converted to any string format.

Great Explanation from the link : http://geekswithblogs.net/dlussier/archive/2009/11/21/136454.aspx

Let's First look at MVC

The input is directed at the Controller first, not the view. That input might be coming from a user interacting with a page, but it could also be from simply entering a specific url into a browser. In either case, its a Controller that is interfaced with to kick off some functionality.

There is a many-to-one relationship between the Controller and the View. That’s because a single controller may select different views to be rendered based on the operation being executed.

There is one way arrow from Controller to View. This is because the View doesn’t have any knowledge of or reference to the controller.

The Controller does pass back the Model, so there is knowledge between the View and the expected Model being passed into it, but not the Controller serving it up.

MVP – Model View Presenter

Now let’s look at the MVP pattern. It looks very similar to MVC, except for some key distinctions:

The input begins with the View, not the Presenter.

There is a one-to-one mapping between the View and the associated Presenter.

The View holds a reference to the Presenter. The Presenter is also reacting to events being triggered from the View, so its aware of the View its associated with.

The Presenter updates the View based on the requested actions it performs on the Model, but the View is not Model aware.

MVVM – Model View View Model

So with the MVC and MVP patterns in front of us, let’s look at the MVVM pattern and see what differences it holds:

The input begins with the View, not the View Model.

While the View holds a reference to the View Model, the View Model has no information about the View. This is why its possible to have a one-to-many mapping between various Views and one View Model…even across technologies. For example, a WPF View and a Silverlight View could share the same View Model.

Curently in nested fragment, the nested one(s) are only supported if they are generated programmatically! So at this time no nested fragment layout are supported in xml layout scheme!

I guess this what you are exactly looking for

    def findPath(i_file) :
        lines = open( i_file ).readlines()
        for line in lines :
            if line.startswith( "Path=" ):
                output_line=line[(line.find("Path=")+len("Path=")):]
                return output_line

There exists a newer question what is hitting the problem better asking How do include paths work in Visual Studio?

There is getting revealed the way to do it in the newer versions of VisualStudio

• in the current project only (as the question is set here too) as well as
• for every new project as default

The second is the what the answer of Steve Wilkinson above explains, what is, as he supposed himself, not the what Microsoft would recommend.

To say it the shortway here: do it, but do it in the User-Directory at

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0

in the XML-file

Microsoft.Cpp.Win32.user.props

and/or

Microsoft.Cpp.x64.user.props

and not in the C:\program files - directory, where the unmodified Factory-File of Microsoft is expected to reside.

Then you do it the way as VisualStudio is doing it too and everything is regular.

For more info why to do it alike, see my answer there.

Yep:

WITH tab (
  bla bla
)

INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos (  BatchID,                                                        AccountNo,
APartyNo,
SourceRowID)    

SELECT * FROM tab

Note that this is for SQL Server, which supports multiple CTEs:

WITH x AS (), y AS () INSERT INTO z (a, b, c) SELECT a, b, c FROM y

Teradata allows only one CTE and the syntax is as your example.

If you're using the MVVM pattern you can bind a SelectedRecord property of your VM with SelectedItem of the DataGrid, this way you always have the SelectedValue in you VM. Otherwise you should use the SelectedIndex property of the DataGrid.

TextWatcher didn't work for me as it kept firing for every EditText and messing up each others values.

Here is my solution:

public class ConsultantTSView extends Activity {
    .....

    //Submit is called when I push submit button.
    //I wanted to retrieve all EditText(tsHours) values in my HoursList

    public void submit(View view){

        ListView TSDateListView = (ListView) findViewById(R.id.hoursList);
        String value = ((EditText) TSDateListView.getChildAt(0).findViewById(R.id.tsHours)).getText().toString();
    }
}

Hence by using the getChildAt(xx) method you can retrieve any item in the ListView and get the individual item using findViewById. And it will then give the most recent value.

To round down towards negative infinity, use:

rounded=Math.floor(number);

To round down towards zero (if the number can round to a 32-bit integer between -2147483648 and 2147483647), use:

rounded=number|0;

To round down towards zero (for any number), use:

if(number>0)rounded=Math.floor(number);else rounded=Math.ceil(number);

Extract the common code into a class library project and add that class library project to your solutions. Then you can add a reference to the common code from other projects by adding a project reference to that class library. The advantage of having a project reference as opposed to a binary/assembly reference is that if you change your build configuration to debug, release, custom, etc, the common class library project will be built based on that configuration as well.

I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).

SWFUpload is a good start : http://www.swfupload.org/documentation

jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.

Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html

generally, I make by simple way, whatever, I create a restAPI endpoint for example "localhost/api/method/:lastIdObtained/:countDateToReturn" with theses parameters, you can do it a simple request. in the service, eg. .net

jsonData function(lastIdObtained,countDatetoReturn){
'... write your code as you wish..'
and into select query make a filter
select top countDatetoreturn tt.id,tt.desc
 from tbANyThing tt
where id > lastIdObtained
order by id
}

In Ionic, when I scroll from bottom to top, I pass the zero value, when I get the answer, I set the value of the last id obtained, and when I slide from top to bottom, I pass the last registration id I got

Step 6: C:\> imp UserName/password@localhost file=D:\abc\xyz.dmp log=D:\abc\abc_1.log full=y;

Done....

I hope you Find Right solution here.

Thanks.

Okay, finally figured out where I was remiss. I was under the mistaken notion that I should wrap each DAO method in a transaction. Terribly wrong! I've learned my lesson. I've hauled all the transaction code from all the DAO methods and have set up transactions strictly at the application/manager layer. This has totally solved all my problems. Data is properly lazy loaded as I need it, wrapped up and closed down once I do the commit.

Life is goodly... :)

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!

Ryan Stewart's answer was almost there. In the case where you actually don't want to delete your local changes, there's a workflow you can use to merge:

• Run git status. It will give you a list of unmerged files.
• Merge them (by hand, etc.)
• Run git commit

Git will commit just the merges into a new commit. (In my case, I had additional added files on disk, which weren't lumped into that commit.)

Git then considers the merge successful and allows you to move forward.

One of the way you can ensure that this type of mistake (using string instead of json) doesn't happen is to see what gets printed in the alert. When you do

alert(data)

if data is a string, it will print everything that is contains. However if you print is json object. you will get the following response in the alert

[object Object]

If this the response then you can be sure that you can use this as an object (json in this case).

Thus, you need to convert your string into json first, before using it by doing this:

JSON.parse(data)

Most of the times in Linux, ng serve or ng build --watch doesn't work if the directory doesn't have sufficient permissions.

The solution is either to provide the necessary permissions or to use sudo instead.

UPDATE

watch flag in ng serve is actually redundant as it is the default option. Credit to @Zaphoid for pointing out the mistake.

I used similar approach, but I wanted to

1. Keep the Dialog code as a widget in a separated file so I can reuse it.
2. Blurr the background when the dialog is shown.

Code: 1. alertDialog_widget.dart

import 'dart:ui';
import 'package:flutter/material.dart';


class BlurryDialog extends StatelessWidget {

  String title;
  String content;
  VoidCallback continueCallBack;

  BlurryDialog(this.title, this.content, this.continueCallBack);
  TextStyle textStyle = TextStyle (color: Colors.black);

  @override
  Widget build(BuildContext context) {
    return BackdropFilter(
      filter: ImageFilter.blur(sigmaX: 6, sigmaY: 6),
      child:  AlertDialog(
      title: new Text(title,style: textStyle,),
      content: new Text(content, style: textStyle,),
      actions: <Widget>[
        new FlatButton(
          child: new Text("Continue"),
           onPressed: () {
            continueCallBack();
          },
        ),
        new FlatButton(
          child: Text("Cancel"),
          onPressed: () {
            Navigator.of(context).pop();
          },
        ),
      ],
      ));
  }
}

You can call this in main (or wherever you want) by creating a new method like:

 _showDialog(BuildContext context)
{

  VoidCallback continueCallBack = () => {
 Navigator.of(context).pop(),
    // code on continue comes here

  };
  BlurryDialog  alert = BlurryDialog("Abort","Are you sure you want to abort this operation?",continueCallBack);


  showDialog(
    context: context,
    builder: (BuildContext context) {
      return alert;
    },
  );
}

The args of print_the_arguments is arguments, so you should use:

struct arg_struct *args = (struct arg_struct *)arguments. 

This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.

Building off of @Bohemian, I think the easiest approach would be to just use a regex literal, e.g.:

if (name.search(/[\[\]?*+|{}\\()@.\n\r]/) != -1) {
    // ... stuff ...
}

Regex literals are nice because you don't have to escape the escape character, and some IDE's will highlight invalid regex (very helpful for me as I constantly screw them up).

Adding to @adardesign's answer, if you want to reset all files that have been added to assume-unchanged list to no-assume-unchanged in one go, you can do the following:

git ls-files -v | grep '^h' | sed 's/^..//' | sed 's/\ /\\ /g' | xargs -I FILE git update-index --no-assume-unchanged FILE || true

This will just strip out the two characters output from grep i.e. "h ", then escape any spaces that may be present in file names, and finally || true will prevent the command to terminate prematurely in case some files in the loop has errors.

I was having the same exact problem, I wasnt being asked for a password, and it seems that I had the wrong path for the keystore file.

In fact, if the keytool doesn't find the keystore you have set, it will create one and give you the wrong key since it isn't using the correct one.

The general rule is that if you aren't being asked for a password then you have the wrong key being generated.

cout << '\a';

Edit: I feel like this was too simple an answer for the rep so here's something that you may also find helpful.

In PHP we can find the absolute value of an integer by using the abs() function. For example if I were trying to work out the difference between two figures I could do this:

$turnover = 10000;
$overheads = 12500;

$difference = abs($turnover-$overheads);

echo "The Difference is ".$difference;

This would produce The Difference is 2500.

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

See file()^{PHP Manual}:

$url    = 'http://mixednews.ru/wp-content/uploads/2011/10/0ed9320413f3ba172471860e77b15587.jpg';
$img    = 'miki.png';
$file   = file($url);
$result = file_put_contents($img, $file)

According to Javascript Date Documentation, you can easily do this way:

var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);

And don't worry about if hours you set will be out of 0..23 range. Date() object will update the date accordingly.

You may want to keep jquery.js deferred for faster page load. However, if jquery.js is deferred the $(window).load may not work. Then you may try

setTimeout(function(){$('#myModal').modal('show');},3000);

it will popup your modal after page is completely loaded (including jquery)

This might be useful to someone ending up here from a search. Make sure you're trying to drop a table and not a view.

SET foreign_key_checks = 0;
-- Drop tables
drop table ...
-- Drop views
drop view ...
SET foreign_key_checks = 1;

SET foreign_key_checks = 0 is to set foreign key checks to off and then SET foreign_key_checks = 1 is to set foreign key checks back on. While the checks are off the tables can be dropped, the checks are then turned back on to keep the integrity of the table structure.

Servlet to be accessible from a browser, then must tell the servlet container what servlets to deploy, and what URL's to map the servlets to. This is done in the web.xml file of your Java web application.

use web.xml in servlet

<servlet>
    <description></description>
    <display-name>servlet class name</display-name>
    <servlet-name>servlet class name</servlet-name>
    <servlet-class>servlet package name/servlet class name</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>servlet class name</servlet-name>
    <url-pattern>/servlet class name</url-pattern>
</servlet-mapping>

manly use web.xml for servlet mapping.

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

In the later PHP version self::staticMethod(); also will not work. It will throw the strict standard error.

In this case, we can create object of same class and call by object

here is the example

class Foo {

    public function fun1() {
        echo 'non-static';   
    }

    public static function fun2() {
        echo (new self)->fun1();
    }
}

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

add margin:-1px; which reduces 1px to each side. or if you need only for side you can do margin-left:-1px etc.

The command

show full processlist

can be replaced by:

SELECT * FROM information_schema.processlist

but if you go with the latter version you can add WHERE clause to it:

SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

The main difference with shell config files is that some are only read by "login" shells (eg. when you login from another host, or login at the text console of a local unix machine). these are the ones called, say, .login or .profile or .zlogin (depending on which shell you're using).

Then you have config files that are read by "interactive" shells (as in, ones connected to a terminal (or pseudo-terminal in the case of, say, a terminal emulator running under a windowing system). these are the ones with names like .bashrc, .tcshrc, .zshrc, etc.

bash complicates this in that .bashrc is only read by a shell that's both interactive and non-login, so you'll find most people end up telling their .bash_profile to also read .bashrc with something like

[[ -r ~/.bashrc ]] && . ~/.bashrc

Other shells behave differently - eg with zsh, .zshrc is always read for an interactive shell, whether it's a login one or not.

The manual page for bash explains the circumstances under which each file is read. Yes, behaviour is generally consistent between machines.

.profile is simply the login script filename originally used by /bin/sh. bash, being generally backwards-compatible with /bin/sh, will read .profile if one exists.

You can also do this with the ol' good method :

String inputLine = "test123";
String translatedString = null;
char[] stringArray = inputLine.toCharArray();
for(int i=0;i<stringArray.length;i++){
      translatedString += Integer.toBinaryString((int) stringArray[i]);
}

Regarding this answer, the snapshot function is deprecated in version 3.6, according to this update. So, on version 3.6 and above, it is possible to perform the operation this way:

db.person.find().forEach(
    function (elem) {
        db.person.update(
            {
                _id: elem._id
            },
            {
                $set: {
                    name: elem.firstname + ' ' + elem.lastname
                }
            }
        );
    }
);

Here is alternative code:

javascript:(function() {var url = '//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js'; var n=document.createElement('script');n.setAttribute('language','JavaScript');n.setAttribute('src',url+'?rand='+new Date().getTime());document.body.appendChild(n);})();

which can be pasted either directly in Console or create a new Bookmark page (in Chrome right-click on the Bookmark Bar, Add Page...) and paste this code as URL.

To test if that worked, see below.

Before:

$()
Uncaught TypeError: $ is not a function(…)

After:

$()
[]

The default timeout is defined by default_socket_timeout ini-setting, which is 60 seconds. You can also change it on the fly:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

Another way to set a timeout, would be to use stream_context_create to set the timeout as HTTP context options of the HTTP stream wrapper in use:

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);

As mentioned before, the use of x(end+1) = newElem has the advantage that it allows you to concatenate your vector with a scalar, regardless of whether your vector is transposed or not. Therefore it is more robust for adding scalars.

However, what should not be forgotten is that x = [x newElem] will also work when you try to add multiple elements at once. Furthermore, this generalizes a bit more naturally to the case where you want to concatenate matrices. M = [M M1 M2 M3]

All in all, if you want a solution that allows you to concatenate your existing vector x with newElem that may or may not be a scalar, this should do the trick:

 x(end+(1:numel(newElem)))=newElem

Try this:

num1 = num2 = 5;

Note that this won't work in VB.

Emulation is a multi-faceted area. Here are the basic ideas and functional components. I'm going to break it into pieces and then fill in the details via edits. Many of the things I'm going to describe will require knowledge of the inner workings of processors -- assembly knowledge is necessary. If I'm a bit too vague on certain things, please ask questions so I can continue to improve this answer.

Basic idea:

Emulation works by handling the behavior of the processor and the individual components. You build each individual piece of the system and then connect the pieces much like wires do in hardware.

Processor emulation:

There are three ways of handling processor emulation:

• Interpretation
• Dynamic recompilation
• Static recompilation

With all of these paths, you have the same overall goal: execute a piece of code to modify processor state and interact with 'hardware'. Processor state is a conglomeration of the processor registers, interrupt handlers, etc for a given processor target. For the 6502, you'd have a number of 8-bit integers representing registers: A, X, Y, P, and S; you'd also have a 16-bit PC register.

With interpretation, you start at the IP (instruction pointer -- also called PC, program counter) and read the instruction from memory. Your code parses this instruction and uses this information to alter processor state as specified by your processor. The core problem with interpretation is that it's very slow; each time you handle a given instruction, you have to decode it and perform the requisite operation.

With dynamic recompilation, you iterate over the code much like interpretation, but instead of just executing opcodes, you build up a list of operations. Once you reach a branch instruction, you compile this list of operations to machine code for your host platform, then you cache this compiled code and execute it. Then when you hit a given instruction group again, you only have to execute the code from the cache. (BTW, most people don't actually make a list of instructions but compile them to machine code on the fly -- this makes it more difficult to optimize, but that's out of the scope of this answer, unless enough people are interested)

With static recompilation, you do the same as in dynamic recompilation, but you follow branches. You end up building a chunk of code that represents all of the code in the program, which can then be executed with no further interference. This would be a great mechanism if it weren't for the following problems:

• Code that isn't in the program to begin with (e.g. compressed, encrypted, generated/modified at runtime, etc) won't be recompiled, so it won't run
• It's been proven that finding all the code in a given binary is equivalent to the Halting problem

These combine to make static recompilation completely infeasible in 99% of cases. For more information, Michael Steil has done some great research into static recompilation -- the best I've seen.

The other side to processor emulation is the way in which you interact with hardware. This really has two sides:

• Processor timing
• Interrupt handling

Processor timing:

Certain platforms -- especially older consoles like the NES, SNES, etc -- require your emulator to have strict timing to be completely compatible. With the NES, you have the PPU (pixel processing unit) which requires that the CPU put pixels into its memory at precise moments. If you use interpretation, you can easily count cycles and emulate proper timing; with dynamic/static recompilation, things are a /lot/ more complex.

Interrupt handling:

Interrupts are the primary mechanism that the CPU communicates with hardware. Generally, your hardware components will tell the CPU what interrupts it cares about. This is pretty straightforward -- when your code throws a given interrupt, you look at the interrupt handler table and call the proper callback.

Hardware emulation:

There are two sides to emulating a given hardware device:

• Emulating the functionality of the device
• Emulating the actual device interfaces

Take the case of a hard-drive. The functionality is emulated by creating the backing storage, read/write/format routines, etc. This part is generally very straightforward.

The actual interface of the device is a bit more complex. This is generally some combination of memory mapped registers (e.g. parts of memory that the device watches for changes to do signaling) and interrupts. For a hard-drive, you may have a memory mapped area where you place read commands, writes, etc, then read this data back.

I'd go into more detail, but there are a million ways you can go with it. If you have any specific questions here, feel free to ask and I'll add the info.

Resources:

I think I've given a pretty good intro here, but there are a ton of additional areas. I'm more than happy to help with any questions; I've been very vague in most of this simply due to the immense complexity.

Obligatory Wikipedia links:

• Emulator
• Dynamic recompilation

General emulation resources:

• Zophar -- This is where I got my start with emulation, first downloading emulators and eventually plundering their immense archives of documentation. This is the absolute best resource you can possibly have.
• NGEmu -- Not many direct resources, but their forums are unbeatable.
• RomHacking.net -- The documents section contains resources regarding machine architecture for popular consoles

Emulator projects to reference:

• IronBabel -- This is an emulation platform for .NET, written in Nemerle and recompiles code to C# on the fly. Disclaimer: This is my project, so pardon the shameless plug.
• BSnes -- An awesome SNES emulator with the goal of cycle-perfect accuracy.
• MAME -- The arcade emulator. Great reference.
• 6502asm.com -- This is a JavaScript 6502 emulator with a cool little forum.
• dynarec'd 6502asm -- This is a little hack I did over a day or two. I took the existing emulator from 6502asm.com and changed it to dynamically recompile the code to JavaScript for massive speed increases.

Processor recompilation references:

• The research into static recompilation done by Michael Steil (referenced above) culminated in this paper and you can find source and such here.

Addendum:

It's been well over a year since this answer was submitted and with all the attention it's been getting, I figured it's time to update some things.

Perhaps the most exciting thing in emulation right now is libcpu, started by the aforementioned Michael Steil. It's a library intended to support a large number of CPU cores, which use LLVM for recompilation (static and dynamic!). It's got huge potential, and I think it'll do great things for emulation.

emu-docs has also been brought to my attention, which houses a great repository of system documentation, which is very useful for emulation purposes. I haven't spent much time there, but it looks like they have a lot of great resources.

I'm glad this post has been helpful, and I'm hoping I can get off my arse and finish up my book on the subject by the end of the year/early next year.

Why be easy when it can be complicated? Why use third-party applications like netdom.exe when correct interogations is the way? Try 2 interogations:

wmic computersystem where caption='%computername%' get caption, UserName, Domain /format:value

wmic computersystem where "caption like '%%%computername%%%'" get caption, UserName, Domain /format:value

or in a batch file use loop

for /f "tokens=2 delims==" %%i in ('wmic computersystem where "Caption like '%%%currentname%%%'" get UserName /format:value') do (echo. UserName- %%i)

In new version it is like this:

def validate(self, attrs):
    has_unknown_fields = set(self.initial_data) - set(self.fields.keys())
    if has_unknown_fields:
        raise serializers.ValidationError("Do not send extra fields")
    return attrs

If parent dies, PPID of orphans change to 1 - you only need to check your own PPID. In a way, this is polling, mentioned above. here is shell piece for that:

check_parent () {
      parent=`ps -f|awk '$2=='$PID'{print $3 }'`
      echo "parent:$parent"
      let parent=$parent+0
      if [[ $parent -eq 1 ]]; then
        echo "parent is dead, exiting"
        exit;
      fi
}


PID=$$
cnt=0
while [[ 1 = 1 ]]; do
  check_parent
  ... something
done

The current windows 10 (Version 1803 (OS Build 17134.1)) has SSH built in. With that, just enable SSH from the Control Panel, Terminal & SNMP, be sure you are using an account in the Administrator's group, and you're all set.

Launch Powershell or CMD, enter ssh yourAccountName@diskstation

The first time it will cache off your certificate.

It's actually fairly easy to set the underline color of an EditText programmatically (just one line of code).

To set the color:

editText.getBackground().setColorFilter(color, PorterDuff.Mode.SRC_IN);

To remove the color:

editText.getBackground().clearColorFilter();

Note: when the EditText has focus on, the color you set won't take effect, instead, it has a focus color.

API Reference:

Drawable#setColorFilter

Drawable#clearColorFilter

No, you don't have to bother grep.

Consider the code below.

def return_something(someint):
 if  someint > 5:
    return someint

y = return_something(2)
y.real()

This is going to give you the error

AttributeError: 'NoneType' object has no attribute 'real'

So points are as below.

1. In the code, a function or class method is not returning anything or returning the None
2. Then you try to access an attribute of that returned object(which is None), causing the error message.

public Image byteArrayToImage(byte[] bytesArr)
{
    using (MemoryStream memstr = new MemoryStream(bytesArr))
    {
        Image img = Image.FromStream(memstr);
        return img;
    }
}

swift 4.2 and above

using button's IBOutlet

btnOutlet.setTitle("New Title", for: .normal)

using button's IBAction

@IBAction func btnAction(_ sender: UIButton) {
  sender.setTitle("New Title", for: .normal)
}

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.
// Calling it explicitly ensures each integer is created 
// as a separate object as intended.

You entity is not correctly annotated, you must use the @javax.persistence.Entity annotation. You can use the Hibernate extension @org.hibernate.annotations.Entity to go beyond what JPA has to offer but the Hibernate annotation is not a replacement, it's a complement.

So change your code into:

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
public class Message { 
    ...  
}

There are multiple answers based on what you are doing with the string.

1) Using the string as an id (will not be modified). Passing it in by const reference is probably the best idea here: (std::string const&)

2) Modifying the string but not wanting the caller to see that change. Passing it in by value is preferable: (std::string)

3) Modifying the string but wanting the caller to see that change. Passing it in by reference is preferable: (std::string &)

4) Sending the string into the function and the caller of the function will never use the string again. Using move semantics might be an option (std::string &&)

This should handle cases of clicking on [x] or ALT+F4

   if (e.CloseReason == CloseReason.UserClosing)

      if (result == DialogResult.Yes)
      {
          Environment.Exit(0);
      }
      else 
      {
         e.Cancel = true;

This function will do as JohnFx suggested and allow for varied lengths on the arrays

Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim bi As Long
    Dim i As Long
    Dim newind As Long

        ub1 = UBound(arr1) + 1
        ub2 = UBound(arr2) + 1

        bi = IIf(ub1 >= ub2, ub1, ub2)

        ReDim holdarr(ub1 + ub2 - 1)

        For i = 0 To bi
            If i < ub1 Then
                holdarr(newind) = arr1(i)
                newind = newind + 1
            End If

            If i < ub2 Then
                holdarr(newind) = arr2(i)
                newind = newind + 1
            End If
        Next i

        mergeArrays = holdarr
End Function

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

Even if my answer wont be accepted as the correct answer, I just feel all these answers above caused me to have more problems here is how I fixed it

1. Get Sublime Text (crazy, right? No, just follow my steps)
2. Click on file and select open folder, then choose the folder of the project you are working on
3. Now click on Find from the Tabs, and select find in files or just do Ctrl + Shift + F (for Windows users, for mac users you already know the drill)
4. Now copy and paste exactly the name of the package you want to change in the Find section and paste in the replace section what you would like to replace the package name with.
5. Click on FIND (do not click on REPLACE just yet).
6. Now clicking on Find lists all available package name in your project which matches your search criteria, if you are satisfied with this then repeat from no. 3 but this time click on REPLACE.
7. Rebuild your project and have fun

Conclusion: a simple find and replace program is all you need to sort this problem out, and I strongly recommend Sublime Text 3 for that.

There is a React module called react-client-session that makes storing client side session data very easy. The git repo is here.

This is implemented in a similar way as the closure approach in my other answer, however it also supports persistence using 3 different persistence stores. The default store is memory(not persistent).

1. Cookie
2. localStorage
3. sessionStorage

After installing, just set the desired store type where you mount the root component ...

import ReactSession from 'react-client-session';

ReactSession.setStoreType("localStorage");

... and set/get key value pairs from anywhere in your app:

import ReactSession from 'react-client-session';

ReactSession.set("username", "Bob");
ReactSession.get("username");  // Returns "Bob"

Found a solution to this. Just ISNULL the CASE statement:

ISNULL(CASE x WHEN x THEN x ELSE x END, '') AS 'BLAH'

The "cd" command changes the directory, but not what drive you are working with. So when you go "cd d:\temp", you are changing the D drive's directory to temp, but staying in the C drive.

Execute these two commands:

D:
cd temp

That will get you the results you want.

You might changed your drive-letter: once u had installed eclipse on D:\, after windows reinstall the drive-letter is now E:\ (for example).

look into eclipse.ini in your eclipse folder, there are some lines where the drive-letter is still D:\

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

performSelector:withObject:withObject:

You might also want to mention that this method is only for passing maximum 2 arguments, and it cannot be delayed. (such as performSelector:withObject:afterDelay:).

kinda weird that apple only supports 2 objects to be send and didnt make it more generic.

List iterators guarantee first and foremost that you get the list's elements in the internal order of the list (aka. insertion order). More specifically it is in the order you've inserted the elements or on how you've manipulated the list. Sorting can be seen as a manipulation of the data structure, and there are several ways to sort the list.

I'll order the ways in the order of usefulness as I personally see it:

1. Consider using Set or Bag collections instead

NOTE: I put this option at the top because this is what you normally want to do anyway.

A sorted set automatically sorts the collection at insertion, meaning that it does the sorting while you add elements into the collection. It also means you don't need to manually sort it.

Furthermore if you are sure that you don't need to worry about (or have) duplicate elements then you can use the TreeSet<T> instead. It implements SortedSet and NavigableSet interfaces and works as you'd probably expect from a list:

TreeSet<String> set = new TreeSet<String>();
set.add("lol");
set.add("cat");
// automatically sorts natural order when adding

for (String s : set) {
    System.out.println(s);
}
// Prints out "cat" and "lol"

If you don't want the natural ordering you can use the constructor parameter that takes a Comparator<T>.

Alternatively, you can use Multisets (also known as Bags), that is a Set that allows duplicate elements, instead and there are third-party implementations of them. Most notably from the Guava libraries there is a TreeMultiset, that works a lot like the TreeSet.

2. Sort your list with Collections.sort()

As mentioned above, sorting of Lists is a manipulation of the data structure. So for situations where you need "one source of truth" that will be sorted in a variety of ways then sorting it manually is the way to go.

You can sort your list with the java.util.Collections.sort() method. Here is a code sample on how:

List<String> strings = new ArrayList<String>()
strings.add("lol");
strings.add("cat");

Collections.sort(strings);
for (String s : strings) {
    System.out.println(s);
}
// Prints out "cat" and "lol"

Using comparators

One clear benefit is that you may use Comparator in the sort method. Java also provides some implementations for the Comparator such as the Collator which is useful for locale sensitive sorting strings. Here is one example:

Collator usCollator = Collator.getInstance(Locale.US);
usCollator.setStrength(Collator.PRIMARY); // ignores casing

Collections.sort(strings, usCollator);

Sorting in concurrent environments

Do note though that using the sort method is not friendly in concurrent environments, since the collection instance will be manipulated, and you should consider using immutable collections instead. This is something Guava provides in the Ordering class and is a simple one-liner:

List<string> sorted = Ordering.natural().sortedCopy(strings);

3. Wrap your list with java.util.PriorityQueue

Though there is no sorted list in Java there is however a sorted queue which would probably work just as well for you. It is the java.util.PriorityQueue class.

Nico Haase linked in the comments to a related question that also answers this.

In a sorted collection you most likely don't want to manipulate the internal data structure which is why PriorityQueue doesn't implement the List interface (because that would give you direct access to its elements).

Caveat on the PriorityQueue iterator

The PriorityQueue class implements the Iterable<E> and Collection<E> interfaces so it can be iterated as usual. However, the iterator is not guaranteed to return elements in the sorted order. Instead (as Alderath points out in the comments) you need to poll() the queue until empty.

Note that you can convert a list to a priority queue via the constructor that takes any collection:

List<String> strings = new ArrayList<String>()
strings.add("lol");
strings.add("cat");

PriorityQueue<String> sortedStrings = new PriorityQueue(strings);
while(!sortedStrings.isEmpty()) {
    System.out.println(sortedStrings.poll());
}
// Prints out "cat" and "lol"

4. Write your own SortedList class

NOTE: You shouldn't have to do this.

You can write your own List class that sorts each time you add a new element. This can get rather computation heavy depending on your implementation and is pointless, unless you want to do it as an exercise, because of two main reasons:

1. It breaks the contract that List<E> interface has because the add methods should ensure that the element will reside in the index that the user specifies.
2. Why reinvent the wheel? You should be using the TreeSet or Multisets instead as pointed out in the first point above.

However, if you want to do it as an exercise here is a code sample to get you started, it uses the AbstractList abstract class:

public class SortedList<E> extends AbstractList<E> {

    private ArrayList<E> internalList = new ArrayList<E>();

    // Note that add(E e) in AbstractList is calling this one
    @Override 
    public void add(int position, E e) {
        internalList.add(e);
        Collections.sort(internalList, null);
    }

    @Override
    public E get(int i) {
        return internalList.get(i);
    }

    @Override
    public int size() {
        return internalList.size();
    }

}

Note that if you haven't overridden the methods you need, then the default implementations from AbstractList will throw UnsupportedOperationExceptions.

Global variables certainly do exist in GAS, but you must understand the client/server relationship of the environment in order to use them correctly - please see this question: Global variables in Google Script (spreadsheet)

However this is not the problem with your code; the documentation indicates that the function to be executed by the menu must be supplied to the method as a string, right now you are supplying the output of the function: https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#addMenu%28String,Object%29

function MainMenu_Init() {
    Logger.log('init');  
};

function onOpen() {
    var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
    var menus = [{
        name: "Init",
        functionName: "MainMenu_Init"
    }];
    spreadsheet.addMenu("Test", menus);
};

It is as simple as this:

var sel = document.getElementById('sel');
var button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;
    sel.onchange();
});

But this way has a problem. You can't call events just like you would, with normal functions, because there may be more than one function listening for an event, and they can get set in several different ways.

Unfortunately, the 'right way' to fire an event is not so easy because you have to do it differently in Internet Explorer (using document.createEventObject) and Firefox (using document.createEvent("HTMLEvents"))

var sel = document.getElementById('sel');
var button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;
    fireEvent(sel,'change');

});


function fireEvent(element,event){
    if (document.createEventObject){
    // dispatch for IE
    var evt = document.createEventObject();
    return element.fireEvent('on'+event,evt)
    }
    else{
    // dispatch for firefox + others
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent(event, true, true ); // event type,bubbling,cancelable
    return !element.dispatchEvent(evt);
    }
}

For the problem you're having about the batch file asking the user if the destination is a folder or file, if you know the answer in advance, you can do as such:

If destination is a file: echo f | [batch file path]

If folder: echo d | [batch file path]

It will essentially just pipe the letter after "echo" to the input of the batch file.

A simple regex should be efficent to check your textarea:

/\s*\d+\s*\n/g.test(text) ? "OK" : "KO"

I faced similar issues with POST Request where GET Request was working fine on my backend which i am passing my variables etc. The problem lies in there that the backend does a lot of redirects, which didnt work with fopen or the php header methods.

So the only way i got it working was to put a hidden form and push over the values with a POST submit when the page is loaded.

echo
'<body onload="document.redirectform.submit()">   
    <form method="POST" action="http://someurl/todo.php" name="redirectform" style="display:none">
    <input name="var1" value=' . $var1. '>
    <input name="var2" value=' . $var2. '>
    <input name="var3" value=' . $var3. '>
    </form>
</body>';

<TextView
                android:id="@+id/layone"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Previous Page"
                android:textColor="#000000"
                android:textSize="16dp"
                android:paddingLeft="10dp"
                android:layout_marginTop="10dp"
                android:visibility="gone" />

layone is a TextView.
You got your id wrong.

LinearLayout layone= (LinearLayout) view.findViewById(R.id.laytwo);// change id here

layone.setVisibility(View.VISIBLE);

should do the job.

or change like this to show the TextView:

TextView layone= (TextView) view.findViewById(R.id.layone);

    layone.setVisibility(View.VISIBLE);

Sometimes this doesn't work if:

1) you have an error in the java script code before your line with $('#myModal').on('show.bs.modal'...). To troubleshoot put an alert message before the line to see if it comes up when you load the page. To resolve eliminate JSs above to see which one is the problem

2) Another problem is if you load up the JS in wrong order. For example you can have the $('#myModal').on('show.bs.modal'...) part before you actually load JQuery.js. In that case your call will be ignored, so first in the HTML (view page source to be sure) check if the script link to JQuery is above your modal onShow call, otherwise it will be ignored. To troubleshoot put an alert inside the on show an one before. If you see the one before and not the one inside the onShow function it is clear that the function cannot execute. If the spelling is right more than likely your call to JQuery.js is not made or it is made after the onShow part

If your Main class is in a package called FileManagement, then try:

java -cp . FileManagement.Main

in the parent folder of the FileManagement folder.

If your Main class is not in a package (the default package) then cd to the FileManagement folder and try:

java -cp . Main

In case this helps someone, I deployed my app to google play, when I uninstalled it and tried to run a debug on my device (new version) I was getting this failed update message.

I couldn't see the app in my device (it was already uninstalled) so I:

Installed the first version again from google play

Opened Settings/App/App name

Cleared the Data

Cleared the Cache

Uninstalled the app

Now you can deploy the debug version again to the device :)

Very easy ... outside "span" element with small font and underline, and inside "font" element with bigger font size.

<span style="font-size:1em;text-decoration:underline;">_x000D_
 <span style="font-size:1.5em;">_x000D_
   Text with big font size and thin underline_x000D_
 </span>_x000D_
</span>

Prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:

<?php

    $dbh = new PDO("mysql:$connstr",  $user, $password);

    $dbh -> exec("set names utf8");

?>

You can create a div with the exact same size as the image.

<div class="imageContainer">Some Text</div>

use the css background-image property to show the image

 .imageContainer {
       width:200px; 
       height:200px; 
       background-image: url(locationoftheimage);
 }

note: this slichtly tampers the semantics of your document. If needed use javascript to inject the div in the place of a real image.

name1 = input("What's your name? ")
age1 = int(input ("how old are you? "))
twentyone = str(21 - int(age1))

if age1<21:
    print ("Hi, " + name1+ " you will be 21 in: " + twentyone + " years.")

else:
    print("You are over the age of 21")

You would need to set DATEFIRST. Take a look at this article. I believe this should help.

Use square bracket around variable name.

var objname = 'myobject';
{[objname]}.value = 'value';

One major note that all new Android developers should know is that any information in Widgets (TextView, Buttons, etc.) will be persisted automatically by Android as long as you assign an ID to them. So that means most of the UI state is taken care of without issue. Only when you need to store other data does this become an issue.

From Android Docs:

The only work required by you is to provide a unique ID (with the android:id attribute) for each widget you want to save its state. If a widget does not have an ID, then it cannot save its state

I had this problem (colons in the target name) because I had -n in my GREP_OPTIONS environment variable. Apparently, this caused configure to generate the Makefile incorrectly.

Is there a more elegant way to write this code?

Use collections.defaultdict:

from collections import defaultdict

dates_dict = defaultdict(list)
for key, date in cur:
    dates_dict[key].append(date)

Your problem may have been due to a deficiency in an earlier version of Swift or of the Xcode Beta. Working with Xcode Version 6.0 (6A279r) on August 21, 2014, your code works as expected with this output:

column: 0 row: 0 value:1.0
column: 0 row: 1 value:4.0
column: 0 row: 2 value:7.0
column: 1 row: 0 value:2.0
column: 1 row: 1 value:5.0
column: 1 row: 2 value:8.0
column: 2 row: 0 value:3.0
column: 2 row: 1 value:6.0
column: 2 row: 2 value:9.0

I just copied and pasted your code into a Swift playground and defined two constants:

let NumColumns = 3, NumRows = 3

I've used Sothink SWF decompiler a couple of times, the only problem is that as project gets more complex, the output of decompiler gets harder to compile back again. But it ensures that you can get your .as files most of the time, compilable fla is a question.

For example, to execute following with command prompt or BATCH file we can use this:

C:\Python27\python.exe "C:\Program files(x86)\dev_appserver.py" --host 0.0.0.0 --post 8080 "C:\blabla\"

Same thing to do with Python, we can do this:

subprocess.Popen(['C:/Python27/python.exe', 'C:\\Program files(x86)\\dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:\\blabla'], shell=True)

or

subprocess.Popen(['C:/Python27/python.exe', 'C:/Program files(x86)/dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:/blabla'], shell=True)

obligatory: "use jQuery"

I've seen pages that put a black or white div that covers everything on top of the page, then remove it on the document.load event. Or you could use .ready in jQuery That being said, it was one of the most anoying web pages I've ever seen, I would advise against it.

Good point about the index in the answer you accepted.

Still, if you really search only on specific DATE or DATE ranges often, then the best solution I found is to add another persisted computed column to your table which would only contain the DATE, and add index on this column:

ALTER TABLE "table1" 
    ADD "column_date" AS CONVERT(DATE, "column_datetime") PERSISTED

Add index on that column:

CREATE NONCLUSTERED INDEX "table1_column_date_nu_nci"
ON  "table1" ( "column_date" ASC )
GO

Then your search will be even faster:

DECLARE  @p_date DATE
SET      @p_date = CONVERT( DATE, '14 AUG 2008', 106 )

SELECT   *
FROM     table1
WHERE    column_date = @p_date

You can use eval() method to declare dynamic variables. But better to use an Array.

for (var i = 0; i < coords.length; ++i) {
    var str ="marker"+ i+" = undefined";
    eval(str);
}

This just happened to me. I was running Aurora (AWS MySQL) and tried to add records to a table. The field marked [Key] in the model was mapped to an auto-incremented field in the table... or so I thought. It was set as Primary Key, but it was not set to auto-increment. So setting it to auto-increment fixed my issue.

Define class method:

class Foo(object):
    bar = 1
    @classmethod
    def bah(cls):    
        print cls.bar

Now if bah() has to be instance method (i.e. have access to self), you can still directly access the class variable.

class Foo(object):
    bar = 1
    def bah(self):    
        print self.bar

I find it easier to think of Joins in the following order:

• CROSS JOIN - a Cartesian product of both tables. ALL joins begin here
• INNER JOIN - a CROSS JOIN with a filter added.
• OUTER JOIN - an INNER JOIN with missing elements (from either LEFT or RIGHT table) added afterward.

Until I figured out this (relatively) simple model, JOINS were always a bit more of a black art. Now they make perfect sense.

Hope this helps more than it confuses.

There's a better way to do this in modern browsers using the vh and vw units.

vh is the viewport height.

So you can try something like this:

<style>
canvas {
  border: solid 2px purple;
  background-color: green;
  width: 100%;
  height: 80vh;
}
</style>

This will distort the aspect ration.

You can keep the aspect ratio by using the same unit for each. Here's an example with a 2:1 aspect ratio:

<style>
canvas {
  width: 40vh;
  height: 80vh;
}
</style>

If you're working with an x64 server, keep in mind that there are different ODBC settings for x86 and x64 applications. The "Data Sources (ODBC)" tool in the Administrative Tools list takes you to the x64 version. To view/edit the x86 ODBC settings, you'll need to run that version of the tool manually:

%windir%\SysWOW64\odbcad32.exe (%windir% is usually C:\Windows)

When your app runs as x64, it will use the x64 data sources, and when it runs as x86, it will use those data sources instead.

float(str(round(answer, 2)))
float(str(round(0.0556781255, 2)))

Here's a piece of code that checks whether a number is an integer or not, it works for both Python 2 and Python 3.

import sys

if sys.version < '3':
    integer_types = (int, long,)
else:
    integer_types = (int,)

isinstance(yourNumber, integer_types)  # returns True if it's an integer
isinstance(yourNumber, float)  # returns True if it's a float

Notice that Python 2 has both types int and long, while Python 3 has only type int. Source.

If you want to check whether your number is a float that represents an int, do this

(isinstance(yourNumber, float) and (yourNumber).is_integer())  # True for 3.0

If you don't need to distinguish between int and float, and are ok with either, then ninjagecko's answer is the way to go

import numbers

isinstance(yourNumber, numbers.Real)

You want to get an element from an empty array. That's why the Size: 0 from the exception

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

So you cant do lstpp.get(0) until you fill the array.

Sure, this can be done using profiles. You can do something like the following in your parent pom.xml.

  ...
   <modules>
      <module>module1</module>
      <module>module2</module>  
      ...
  </modules>
  ...
  <profiles>
     <profile>
       <id>ci</id>
          <modules>
            <module>module1</module>
            <module>module2</module>
            ...
            <module>module-integration-test</module>
          </modules> 
      </profile>
  </profiles>
 ...

In your CI, you would run maven with the ci profile, i.e. mvn -P ci clean install

I didn't get far testing a legacy C application before I started looking for a way to mock functions. I needed mocks badly to isolate the C file I want to test from others. I gave cmock a try and I think I will adopt it.

Cmock scans header files and generates mock functions based on prototypes it finds. Mocks will allow you to test a C file in perfect isolation. All you will have to do is to link your test file with mocks instead of your real object files.

Another advantage of cmock is that it will validate parameters passed to mocked functions, and it will let you specify what return value the mocks should provide. This is very useful to test different flows of execution in your functions.

Tests consist of the typical testA(), testB() functions in which you build expectations, call functions to test and check asserts.

The last step is to generate a runner for your tests with unity. Cmock is tied to the unity test framework. Unity is as easy to learn as any other unit test framework.

Well worth a try and quite easy to grasp:

http://sourceforge.net/apps/trac/cmock/wiki

Update 1

Another framework I am investigating is Cmockery.

http://code.google.com/p/cmockery/

It is a pure C framework supporting unit testing and mocking. It has no dependency on ruby (contrary to Cmock) and it has very little dependency on external libs.

It requires a bit more manual work to setup mocks because it does no code generation. That does not represent a lot of work for an existing project since prototypes won't change much: once you have your mocks, you won't need to change them for a while (this is my case). Extra typing provides complete control of mocks. If there is something you don't like, you simply change your mock.

No need of a special test runner. You only need need to create an array of tests and pass it to a run_tests function. A bit more manual work here too but I definitely like the idea of a self-contained autonomous framework.

Plus it contains some nifty C tricks I didn't know.

Overall Cmockery needs a bit more understanding of mocks to get started. Examples should help you overcome this. It looks like it can do the job with simpler mechanics.

In addition to the repository permissions, the /tmp directory must also be writeable by all users.

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

You cant style the alt attribute directly in css. However the alt will inherit the styles of the item the alt is on or what is inherited by its parent:

    <div style="background-color:black; height: 50px; width: 50px; color:white;">_x000D_
    <img src="ouch" alt="here i am"/>_x000D_
    <div>

In the above example, the alt text will be black. However with the color:white the alt text is white.

You can use C++20 std::format or the fmt::format function from the {fmt} library, std::format is based on:

#include <fmt/core.h>

int main()
  std::string s = fmt::format("{:.2f}", 3.14159265359); // s == "3.14"
}

where 2 is a precision.

As shown by @Maglob, the basic approach is to test the conversion from string to date using SimpleDateFormat.parse. That will catch invalid day/month combinations like 2008-02-31.

However, in practice that is rarely enough since SimpleDateFormat.parse is exceedingly liberal. There are two behaviours you might be concerned with:

Invalid characters in the date string Surprisingly, 2008-02-2x will "pass" as a valid date with locale format = "yyyy-MM-dd" for example. Even when isLenient==false.

Years: 2, 3 or 4 digits? You may also want to enforce 4-digit years rather than allowing the default SimpleDateFormat behaviour (which will interpret "12-02-31" differently depending on whether your format was "yyyy-MM-dd" or "yy-MM-dd")

A Strict Solution with the Standard Library

So a complete string to date test could look like this: a combination of regex match, and then a forced date conversion. The trick with the regex is to make it locale-friendly.

  Date parseDate(String maybeDate, String format, boolean lenient) {
    Date date = null;

    // test date string matches format structure using regex
    // - weed out illegal characters and enforce 4-digit year
    // - create the regex based on the local format string
    String reFormat = Pattern.compile("d+|M+").matcher(Matcher.quoteReplacement(format)).replaceAll("\\\\d{1,2}");
    reFormat = Pattern.compile("y+").matcher(reFormat).replaceAll("\\\\d{4}");
    if ( Pattern.compile(reFormat).matcher(maybeDate).matches() ) {

      // date string matches format structure, 
      // - now test it can be converted to a valid date
      SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance();
      sdf.applyPattern(format);
      sdf.setLenient(lenient);
      try { date = sdf.parse(maybeDate); } catch (ParseException e) { }
    } 
    return date;
  } 

  // used like this:
  Date date = parseDate( "21/5/2009", "d/M/yyyy", false);

Note that the regex assumes the format string contains only day, month, year, and separator characters. Aside from that, format can be in any locale format: "d/MM/yy", "yyyy-MM-dd", and so on. The format string for the current locale could be obtained like this:

Locale locale = Locale.getDefault();
SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance(DateFormat.SHORT, locale );
String format = sdf.toPattern();

Joda Time - Better Alternative?

I've been hearing about joda time recently and thought I'd compare. Two points:

1. Seems better at being strict about invalid characters in the date string, unlike SimpleDateFormat
2. Can't see a way to enforce 4-digit years with it yet (but I guess you could create your own DateTimeFormatter for this purpose)

It's quite simple to use:

import org.joda.time.format.*;
import org.joda.time.DateTime;

org.joda.time.DateTime parseDate(String maybeDate, String format) {
  org.joda.time.DateTime date = null;
  try {
    DateTimeFormatter fmt = DateTimeFormat.forPattern(format);
    date =  fmt.parseDateTime(maybeDate);
  } catch (Exception e) { }
  return date;
}

Here's a solution with nested list comprehensions, os.walk and simple suffix matching instead of glob:

import os
cfiles = [os.path.join(root, filename)
          for root, dirnames, filenames in os.walk('src')
          for filename in filenames if filename.endswith('.c')]

It can be compressed to a one-liner:

import os;cfiles=[os.path.join(r,f) for r,d,fs in os.walk('src') for f in fs if f.endswith('.c')]

or generalized as a function:

import os

def recursive_glob(rootdir='.', suffix=''):
    return [os.path.join(looproot, filename)
            for looproot, _, filenames in os.walk(rootdir)
            for filename in filenames if filename.endswith(suffix)]

cfiles = recursive_glob('src', '.c')

If you do need full glob style patterns, you can follow Alex's and Bruno's example and use fnmatch:

import fnmatch
import os

def recursive_glob(rootdir='.', pattern='*'):
    return [os.path.join(looproot, filename)
            for looproot, _, filenames in os.walk(rootdir)
            for filename in filenames
            if fnmatch.fnmatch(filename, pattern)]

cfiles = recursive_glob('src', '*.c')

>>> x = 'it is icy'.replace('i', '', 1)
>>> x
't is icy'

Since your code would only replace the first instance, I assumed that's what you wanted. If you want to replace them all, leave off the 1 argument.

Since you cannot replace the character in the string itself, you have to reassign it back to the variable. (Essentially, you have to update the reference instead of modifying the string.)

You can also use the PostAsJsonAsync() method available in HttpClient()

   var requestObj= JsonConvert.SerializeObject(obj);_x000D_
   HttpResponseMessage response = await    client.PostAsJsonAsync($"endpoint",requestObj).ConfigureAwait(false);

I did find any of these solutions met my requirements, so made my own version of node called node2exe that does this. It's available from https://github.com/areve/node2exe

To add to the previous answers, if you have a tarball image, you can simply load it to you local docker set of images docker image load -i /path/image.tar .Please remember to run it after eval $(minikube docker-env), since minikube does not share images with the locally installed docker engine.

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

\d{1}(\.\d{1,3})?

Match a single digit 0..9 «\d{1}»
   Exactly 1 times «{1}»
Match the regular expression below and capture its match into backreference number 1 «(\.\d{1,3})?»
   Between zero and one times, as many times as possible, giving back as needed (greedy) «?»
   Match the character “.” literally «\.»
   Match a single digit 0..9 «\d{1,3}»
      Between one and 3 times, as many times as possible, giving back as needed (greedy) «{1,3}»

The core reason is quite simple: Python does not find its modules directory, so it can of course not load encodings, too

Python doc on embedding says "Py_Initialize() calculates the module search path based upon its best guess" ... "In particular, it looks for a directory named lib/pythonX.Y"

Yet, if the modules are installed in (just) lib - relative to the python binary - above guess is wrong.

Although docs says that PYTHONHOME and PYTHONPATH are regarded, we observed that this was not the case; their actual presence or content was completely irrelevant.

The only thing that had an effect was a call to Py_SetPath() with e.g. [path-to]\lib as argument before Py_Initialize().

Sure this is only an option for an embedding scenario where one has direct access and control over the code; with a ready-made solution, special steps may be necessary to solve the issue.

    function trbl(e, relative) {
            var r = $(e).get(0).getBoundingClientRect(); relative = $(relative);

            return {
                    t : r.top    + relative['scrollTop'] (),
                    r : r.right  + relative['scrollLeft'](),
                    b : r.bottom + relative['scrollTop'] (),
                    l : r.left   + relative['scrollLeft']() 

            }
    }

    // Example
    trbl(e, window);

Numpy's arange function can be applied to dates:

import numpy as np
from datetime import datetime, timedelta
d0 = datetime(2009, 1,1)
d1 = datetime(2010, 1,1)
dt = timedelta(days = 1)
dates = np.arange(d0, d1, dt).astype(datetime)

The use of astype is to convert from numpy.datetime64 to an array of datetime.datetime objects.

If you are running your application on Microsoft Windows, the path to dynamic libraries (.dll) need to be defined in the PATH environment variable.

If you are running your application on UNIX, the path to your dynamic libraries (.so) need to be defined in the LD_LIBRARY_PATH environment variable.

Very quickly and sortly-code implementation by using the lambda operator.

In [17]: percent = lambda part, whole:float(whole) / 100 * float(part)
In [18]: percent(5,400)

In [19]: percent(5,435)
Out[19]: 21.75

Take your pick:

def my_view(request):

    if request.method == 'POST':
        print request.POST.get('my_field')

        form = MyForm(request.POST)

        print form['my_field'].value()
        print form.data['my_field']

        if form.is_valid():

            print form.cleaned_data['my_field']
            print form.instance.my_field

            form.save()
            print form.instance.id  # now this one can access id/pk

Note: the field is accessed as soon as it's available.

Late Entry.

Following is a succinct implementation using Java8 streams, a one liner:

String foobarspam = "foobarspam";
AtomicInteger splitCounter = new AtomicInteger(0);
Collection<String> splittedStrings = foobarspam
                                    .chars()
                                    .mapToObj(_char -> String.valueOf((char)_char))
                                    .collect(Collectors.groupingBy(stringChar -> splitCounter.getAndIncrement() / 3
                                                                ,Collectors.joining()))
                                    .values();

Output:

[foo, bar, spa, m]

C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.

When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.

Another solution I've found is NOT to use the transformations but just have a separate config file, e.g. app.Release.config. Then add this line to your csproj file.

  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
    <AppConfig>App.Release.config</AppConfig>
  </PropertyGroup>

This will not only generate the right myprogram.exe.config file but if you're using Setup and Deployment Project in Visual Studio to generate MSI, it'll force the deployment project to use the correct config file when packaging.

Here is a short script which checks if the console is available. If it is not, it tries to load Firebug and if Firebug is not available it loads Firebug Lite. Now you can use console.log in any browser. Enjoy!

if (!window['console']) {

    // Enable console
    if (window['loadFirebugConsole']) {
        window.loadFirebugConsole();
    }
    else {
        // No console, use Firebug Lite
        var firebugLite = function(F, i, r, e, b, u, g, L, I, T, E) {
            if (F.getElementById(b))
                return;
            E = F[i+'NS']&&F.documentElement.namespaceURI;
            E = E ? F[i + 'NS'](E, 'script') : F[i]('script');
            E[r]('id', b);
            E[r]('src', I + g + T);
            E[r](b, u);
            (F[e]('head')[0] || F[e]('body')[0]).appendChild(E);
            E = new Image;
            E[r]('src', I + L);
        };
        firebugLite(
            document, 'createElement', 'setAttribute', 'getElementsByTagName',
            'FirebugLite', '4', 'firebug-lite.js',
            'releases/lite/latest/skin/xp/sprite.png',
            'https://getfirebug.com/', '#startOpened');
    }
}
else {
    // Console is already available, no action needed.
}

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

Nginx works as a front end server, which in this case proxies the requests to a node.js server. Therefore you need to setup an nginx config file for node.

This is what I have done in my Ubuntu box:

Create the file yourdomain.com at /etc/nginx/sites-available/:

vim /etc/nginx/sites-available/yourdomain.com

In it you should have something like:

# the IP(s) on which your node server is running. I chose port 3000.
upstream app_yourdomain {
    server 127.0.0.1:3000;
    keepalive 8;
}

# the nginx server instance
server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com www.yourdomain.com;
    access_log /var/log/nginx/yourdomain.com.log;

    # pass the request to the node.js server with the correct headers
    # and much more can be added, see nginx config options
    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;

      proxy_pass http://app_yourdomain/;
      proxy_redirect off;
    }
 }

If you want nginx (>= 1.3.13) to handle websocket requests as well, add the following lines in the location / section:

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

Once you have this setup you must enable the site defined in the config file above:

cd /etc/nginx/sites-enabled/ 
ln -s /etc/nginx/sites-available/yourdomain.com yourdomain.com

Create your node server app at /var/www/yourdomain/app.js and run it at localhost:3000

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

Test for syntax mistakes:

nginx -t

Restart nginx:

sudo /etc/init.d/nginx restart

Lastly start the node server:

cd /var/www/yourdomain/ && node app.js

Now you should see "Hello World" at yourdomain.com

One last note with regards to starting the node server: you should use some kind of monitoring system for the node daemon. There is an awesome tutorial on node with upstart and monit.

As a one-liner:

var result = Regex.Replace(input, @"[^\x00-\x7F]", c => 
    string.Format(@"\u{0:x4}", (int)c.Value[0]));

This is similar to C#'s way of doing it in C++

In C# file.cs you can have private var inside a public function. When in another file you can use it by calling the namespace with the function as in:

MyNamespace.Function(blah);

Here's how to imp the same in C++:

SharedModule.h

class TheDataToBeHidden
{
  public:
    static int _var1;
    static int _var2;
};

namespace SharedData
{
  void SetError(const char *Message, const char *Title);
  void DisplayError(void);
}

SharedModule.cpp

//Init the data (Link error if not done)
int TheDataToBeHidden::_var1 = 0;
int TheDataToBeHidden::_var2 = 0;


//Implement the namespace
namespace SharedData
{
  void SetError(const char *Message, const char *Title)
  {
    //blah using TheDataToBeHidden::_var1, etc
  }

  void DisplayError(void)
  {
    //blah
  }
}

OtherFile.h

#include "SharedModule.h"

OtherFile.cpp

//Call the functions using the hidden variables
SharedData::SetError("Hello", "World");
SharedData::DisplayError();
