You still have access to StreamWriter:

using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"\hereIam.txt"))
{
    file.WriteLine(sb.ToString()); // "sb" is the StringBuilder
}

From the MSDN documentation: Writing to a Text File (Visual C#).

For newer versions of the .NET Framework (Version 2.0. onwards), this can be achieved with one line using the File.WriteAllText method.

System.IO.File.WriteAllText(@"C:\TextFile.txt", stringBuilder.ToString());

Also you can use postgres fdw system

https://www.postgresql.org/docs/9.5/postgres-fdw.html

You will be able to connect different db in postgres. After that, in one query, you can access tables that are in different databases.

There are 72 points per inch; if it is sufficient to assume 96 pixels per inch, the formula is rather simple:

points = pixels * 72 / 96

There is a way to get the configured pixels per inch of your display in Windows using GetDeviceCaps. Microsoft has a guide called "Developing DPI-Aware Applications", look for the section "Creating DPI-Aware Fonts".

The W3C has defined the pixel measurement px as exactly 1/96th of 1in regardless of the actual resolution of your display, so the above formula should be good for all web work.

If you are using dataset to bind in a Grid, you can add the row after you fill in the sql data adapter:

adapter.Fill(ds);
ds.Tables(0).Rows.Add();

If you wanted to learn some GUI, may be tic tac toe is good. Even for console, I still find that is a fun problem. Not challenging but a little bit fun. Later you can advance some other games or port that game to GUI, client server or java applet for the web. I think if you want to learn something and get fun as well, game is a good choice:)

The Most Reliable way to replay har file is using a free tool like Fiddler, the tool is always free and can be downloaded quickly. The sites for the opening har file are all buggy and cannot open large files. Fiddler is available for all platforms.

https://www.telerik.com/download/fiddler

Go to File Menu -> Import Sessions...

Select the "HTTPArchive" Option

Browse to your HAR file

The HAR file will open and replay on the fiddler window.

The best and easy way to get the activity context is putting .this after the name of the Activity. For example: If your Activity's name is SecondActivity, its context will be SecondActivity.this

Yes, the best practice is to check-in (YES, CHECK-IN)

I agree that it will cause a lot of noise or conflict when seeing the diff. But the benefits are:

1. guarantee exact same version of every package. This part is the most important when building in different environments at different times. You may use ^1.2.3 in your package.json, but how can u ensure each time npm install will pick up the same version in your dev machine and in the build server, especially those indirect dependency packages? Well, package-lock.json will ensure that. (With the help of npm ci which installs packages based on lock file)
2. it improves the installation process.
3. it helps with new audit feature npm audit fix (I think the audit feature is from npm version 6).

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

Python has a built-in function called sorted, which will give you a sorted list from any iterable you feed it (such as a list ([1,2,3]); a dict ({1:2,3:4}, although it will just return a sorted list of the keys; a set ({1,2,3,4); or a tuple ((1,2,3,4))).

>>> x = [3,2,1]
>>> sorted(x)
[1, 2, 3]
>>> x
[3, 2, 1]

Lists also have a sort method that will perform the sort in-place (x.sort() returns None but changes the x object) .

>>> x = [3,2,1]
>>> x.sort()
>>> x
[1, 2, 3]

Both also take a key argument, which should be a callable (function/lambda) you can use to change what to sort by.
For example, to get a list of (key,value)-pairs from a dict which is sorted by value you can use the following code:

>>> x = {3:2,2:1,1:5}
>>> sorted(x.items(), key=lambda kv: kv[1])  # Items returns a list of `(key,value)`-pairs
[(2, 1), (3, 2), (1, 5)]

something like below

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
    friends.ForEach(a=>a.msgSentBy='1234');
    db.SaveChanges();
}

UPDATE:

you can update multiple fields as below

friends.ForEach(a =>
                      {
                         a.property1 = value1;
                         a.property2 = value2;
                      });

Because Python really just calls the C language strftime(3) function on your platform, it might be that there are format characters you could use to control the leading zero; try man strftime and take a look. But, of course, the result will not be portable, as the Python manual will remind you. :-)

I would try using a new-style datetime object instead, which has attributes like t.year and t.month and t.day, and put those through the normal, high-powered formatting of the % operator, which does support control of leading zeros. See http://docs.python.org/library/datetime.html for details. Better yet, use the "".format() operator if your Python has it and be even more modern; it has lots of format options for numbers as well. See: http://docs.python.org/library/string.html#string-formatting.

Just run:

$ git update-git-for-windows

Perl approach:

perl -ne 'if($i<1000) { print; } else { print STDERR;}; $i++;' in 1> in.new 2> out && mv in.new in

I think I figured out the problem, this input field is part of a reactive form (?), since you have included formControlName. This means that what you are trying to do by disabling the input field with is_edit is not working, e.g your attempt [disabled]="is_edit", which would in other cases work. With your form you need to do something like this:

toggle() {
  let control = this.myForm.get('name')
  control.disabled ? control.enable() : control.disable();
}

and lose the is_edit altogether.

if you want the input field to be disabled as default, you need to set the form control as:

name: [{value: '', disabled:true}]

Here's a plunker

You will want to check out the jQuery animate() feature. The standard way of doing this is positioning an element absolutely and then animating the "left" or "right" CSS property. An equally popular way is to increase/decrease the left or right margin.

Now, having said this, you need to be aware of severe performance loss for any type of animation that lasts longer than a second or two. Javascript was simply not meant to handle long, sustained, slow animations. This has to do with the way the DOM element is redrawn and recalculated for each "frame" of the animation. If you're doing a page-width animation that lasts more than a couple seconds, expect to see your processor spike by 50% or more. If you're on IE6, prepare to see your computer spontaneously combust into a flaming ball of browser incompetence.

To read up on this, check out this thread (from my very first Stackoverflow post no less)!

Here's a link to the jQuery docs for the animate() feature: http://docs.jquery.com/Effects/animate

Consider using more_itertools.unzip:

>>> from more_itertools import unzip
>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> [list(x) for x in unzip(original)]
[['a', 'b', 'c', 'd'], [1, 2, 3, 4]]     

There is no spoon.

Don't think of statelessness like "sending all your stuff to the server again and again". No way. There will be state, always - database itself is a kind of state after all, you're a registered user, so any set of client-side info won't be valid without the server side. Technically, you're never truly stateless.

The Login Debate

What does it even mean to not keep a session - and log in every time?

Some mean "send the password each time", that's just plain stupid. Some say "nah of course not, send a token instead" - lo and behold, PHP session is doing almost exactly that. It sends a session id which is a kind of token and it helps you reach your personal stuff without resending u/pw every time. It's also quite reliable and well tested. And yes, convenient, which can turn into a drawback, see next paragraph.

Reduce footprint

What you should do, instead, and what makes real sense, is thin your webserver footprint to the minimum. Languages like PHP make it very easy to just stuff everything in the session storage - but sessions have a price tag. If you have several webservers, they need to share session info, because they share the load too - any of them may have to serve the next request.



A shared storage is a must. Server needs to know at least if someone's logged in or not. (And if you bother the database every time you need to decide this, you're practically doomed.) Shared storages need to be a lot faster than the database. This brings the temptation: okay, I have a very fast storage, why not do everything there? - and that's where things go nasty in the other way.

So you're saying, keep session storage to the minimum?

Again, it's your decision. You can store stuff there for performance reasons (database is almost always slower than Redis), you can store information redundantly, implement your own caching, whatever - just keep in mind that web servers will have a bigger load if you store a lot of rubbish on them. Also, if they break under heavy loads (and they will), you lose valuable information; with the REST way of thinking, all that happens in this case is the client sends the same (!) request again and it gets served this time.

How to do it right then?

No one-fits-all solution here. I'd say choose a level of statelessness and go with that. Sessions may be loved by some and hated by others but they're not going anywhere. With every request, send as much information as makes sense, a bit more perhaps; but don't interpret statelessness as not having a session, nor as logging in every time. Somehow the server must know it's you; PHP session ids are one good way, manually generated tokens are another.

Think and decide - don't let design trends think for you.

@qbzenker provided the most idiomatic method IMO

Here are a few alternatives:

In [28]: df.query('Col2 != Col2') # Using the fact that: np.nan != np.nan
Out[28]:
   Col1  Col2  Col3
1     0   NaN   0.0

In [29]: df[np.isnan(df.Col2)]
Out[29]:
   Col1  Col2  Col3
1     0   NaN   0.0

if your using snap package dotnet-sdk on linux this can resolve by updating your ~.bashrc / etc. as follows:

#!/bin/bash
export DOTNET_ROOT=/snap/dotnet-sdk/current
export MSBuildSDKsPath=$DOTNET_ROOT/sdk/$(${DOTNET_ROOT}/dotnet --version)/Sdks
export PATH="${PATH}:${DOTNET_ROOT}"
export PATH="$PATH:$HOME/.dotnet/tools"

I ran into this myself when I wanted to make a thor command under Windows.

To avoid having that message output everytime I ran my thor application I temporarily muted warnings while loading thor:

begin
  original_verbose = $VERBOSE
  $VERBOSE = nil
  require "thor"
ensure
  $VERBOSE = original_verbose
end

That saved me from having to edit third party source files.

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

I agree with much that Manuel has said. In fact, his comments refer to this url...

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4

... which states:

The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

However, for me it would come down to tool/framework support.

• What tools and frameworks do you expect your API users to be building their apps with?
• Do they have frameworks or components they can use that favour one method over the other?

If you get a clear idea of your users, and how they'll make use of your API, then that will help you decide. If you make the upload of files hard for your API users then they'll move away, of you'll spend a lot of time on supporting them.

Secondary to this would be the tool support YOU have for writing your API and how easy it is for your to accommodate one upload mechanism over the other.

Simple solution to emit and show message by Exception.

try {
  throw new TypeError("Error message");
}
catch (e){
  console.log((<Error>e).message);//conversion to Error type
}

Caution

Above is not a solution if we don't know what kind of error can be emitted from the block. In such cases type guards should be used and proper handling for proper error should be done - take a look on @Moriarty answer.

Same thing happened to me. Eventually my solution was to navigate to the repository using terminal (on mac) and create a new js file with a slightly different name. It linked immediately so i copied contents of original file to new one. You also might want to lose the first / after src= and use "".

I can't seem to make that work without hacks either, so what I did was just use the drop-down menu in place of a select box and send the info through a hidden field, like so (using your code):

http://bootply.com/93417

Jquery:

$('.dropdown-menu li').click(function(e){
e.preventDefault();
  var selected = $(this).text();
  $('.category').val(selected);  
});

HTML:

<div class="container">
    <div class="col-sm-7 pull-right well">
      <form class="form-inline" action="#" method="get">
        <div class="input-group col-sm-8">
          <input class="form-control" type="text" value="" placeholder="Search" name="q">
       <div class="input-group-btn">
        <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Select <span class="caret"></span></button>
        <ul class="dropdown-menu">
          <li><a href="#">1</a></li>
          <li><a href="#">2</a></li>
          <li><a href="#">3</a></li>
        </ul>
         <input type="hidden" name="category" class="category">
      </div><!-- /btn-group -->
        </div>
        <button class="btn btn-primary col-sm-3 pull-right" type="submit">Search</button>
      </form>
    </div>
</div>

Not sure if that will work for what you want, but it is an option for you.

Find() will find the element that matches the predicate that you pass as a parameter, so it is not related to Equals() or the == operator.

var element = myList.Find(e => [some condition on e]);

In this case, I have used a lambda expression as a predicate. You might want to read on this. In the case of Find(), your expression should take an element and return a bool.

In your case, that would be:

var reponse = list.Find(r => r.Statement == "statement1")

And to answer the question in the comments, this is the equivalent in .NET 2.0, before lambda expressions were introduced:

var response = list.Find(delegate (Response r) {
    return r.Statement == "statement1";
});

you can use convert function :

Select convert(int,[Column1])

Here is the example:

var charCode = "a".charCodeAt(0);_x000D_
console.log(charCode);

Or if you have longer strings:

var string = "Some string";_x000D_
_x000D_
for (var i = 0; i < string.length; i++) {_x000D_
  console.log(string.charCodeAt(i));_x000D_
}

String.charCodeAt(x) method will return ASCII character code at a given position.

try a negative margin.

margin-top: -10px; /* as an example */

I would use:

self.childView.center = CGPointMake(CGRectGetMidX(self.parentView.bounds),
                                    CGRectGetMidY(self.parentView.bounds));

I like to use the CGRect options...

SWIFT 3:

self.childView.center = CGPoint(x: self.parentView.bounds.midX,
                                        y: self.parentView.bounds.midY);

I think, the easiest way, is to get video info in JSON format. If you want to use JavaScript, try jQuery.getJSON()... But I prefer PHP:

<?php
$video_ID = 'your-video-ID';
$JSON = file_get_contents("https://gdata.youtube.com/feeds/api/videos/{$video_ID}?v=2&alt=json");
$JSON_Data = json_decode($JSON);
$views = $JSON_Data->{'entry'}->{'yt$statistics'}->{'viewCount'};
echo $views;
?>

You can change the default location of .m2 directory in m2.conf file. It resides in your maven installation directory.

add modify this line in

m2.conf

set maven.home C:\Users\me\.m2

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

You need to capture from regex. search for the pattern, if found, retrieve the string using group(index). Assuming valid checks are performed:

>>> p = re.compile("name (.*) is valid")
>>> result = p.search(s)
>>> result
<_sre.SRE_Match object at 0x10555e738>
>>> result.group(1)     # group(1) will return the 1st capture (stuff within the brackets).
                        # group(0) will returned the entire matched text.
'my_user_name'

You can try this too
Type 1
public void YourMethod(int a=0, int b = 0) { //some code }

Type 2
public void YourMethod(int? a, int? b) { //some code }

 LocalDate monthstart = LocalDate.of(year,month,1);
 LocalDate monthend = monthstart.plusDays(monthstart.lengthOfMonth()-1);

There is no standard JSON representation of dates. You should do what @jAndy suggested and not serialize a DateTime at all; just send an RFC 1123 date string ToString("r") or a seconds-from-Unix-epoch number, or something else that you can use in the JavaScript to construct a Date.

Another solution if you want to keep this column as index.

pd.read_csv('filename.csv', index_col='Unnamed: 0')

    EditText ET1 = (EditText) findViewById(R.id.editText1);

    PackageInfo pinfo;
    try {
        pinfo = getPackageManager().getPackageInfo(getPackageName(), 0);
        String versionName = pinfo.versionName;
        ET1.setText(versionName);
        //ET2.setText(versionNumber);
    } catch (NameNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

For reference I was looking at the same problem, I wanted to join the string value of stream elements in the reverse order.

itemList = { last, middle, first } => first,middle,last

I started to use an intermediate collection with collectingAndThen from comonad or the ArrayDeque collector of Stuart Marks, although I wasn't happy with intermediate collection, and streaming again

itemList.stream()
        .map(TheObject::toString)
        .collect(Collectors.collectingAndThen(Collectors.toList(),
                                              strings -> {
                                                      Collections.reverse(strings);
                                                      return strings;
                                              }))
        .stream()
        .collect(Collector.joining());

So I iterated over Stuart Marks answer that was using the Collector.of factory, that has the interesting finisher lambda.

itemList.stream()
        .collect(Collector.of(StringBuilder::new,
                             (sb, o) -> sb.insert(0, o),
                             (r1, r2) -> { r1.insert(0, r2); return r1; },
                             StringBuilder::toString));

Since in this case the stream is not parallel, the combiner is not relevant that much, I'm using insert anyway for the sake of code consistency but it does not matter as it would depend of which stringbuilder is built first.

I looked at the StringJoiner, however it does not have an insert method.

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

You can use the localStorage.key(index) function to return the string representation, where index is the nth object you want to retrieve.

To activate the cursor and select the columns you want to select use:

Windows: Alt+Shift+A

Mac: command + option + A

Linux-based OS: Alt+Shift+A

To deactivate, press the keys again.

This information was taken from DJ's Java Blog.

Concatenating the columns together in some form is a "hack", but when the product doesn't support semi-joins for more than one column, sometimes you have no choice.

Example of where inner/outer join solution would not work:

select * from T1 
 where <boolean expression>
   and (<boolean expression> OR (ColA, ColB) in (select A, B ...))
   and <boolean expression>
   ...

When the queries aren't trivial in nature sometimes you don't have access to the base table set to perform regular inner/outer joins.

If you do use this "hack", when you combine fields just be sure to add enough of a delimiter in between them to avoid misinterpretations, e.g. ColA + ":-:" + ColB

I liked the python-slugify approach here but it was stripping dots also away which was not desired. So I optimized it for uploading a clean filename to s3 this way:

pip install python-slugify

Example code:

s = 'Very / Unsafe / file\nname hähä \n\r .txt'
clean_basename = slugify(os.path.splitext(s)[0])
clean_extension = slugify(os.path.splitext(s)[1][1:])
if clean_extension:
    clean_filename = '{}.{}'.format(clean_basename, clean_extension)
elif clean_basename:
    clean_filename = clean_basename
else:
    clean_filename = 'none' # only unclean characters

Output:

>>> clean_filename
'very-unsafe-file-name-haha.txt'

This is so failsafe, it works with filenames without extension and it even works for only unsafe characters file names (result is none here).

            Directory.CreateDirectory(uploadPath);

        var fileName = Guid.NewGuid() + Path.GetExtension(file.FileName);
        var filePath = Path.Combine(uploadPath, fileName);

        using (var strem = File.Create(filePath))

    if (ModelState.IsValid)
    {
        var fileName = fileService.Upload(vm.DisplayImage);
        student.DisplayImage = fileName;
        getpath = fileName;

        dbContext.Add(student);
        dbContext.SaveChanges();
        TempData["message"] = "Successfully Added";
    }
    return RedirectToAction("Index");
}

the problem can because of MVC MW.you must set formatterType in MVC options:

services.AddMvc(options =>
            {
                options.UseCustomStringModelBinder();
                options.AllowEmptyInputInBodyModelBinding = true;
                foreach (var formatter in options.InputFormatters)
                {
                    if (formatter.GetType() == typeof(SystemTextJsonInputFormatter))
                        ((SystemTextJsonInputFormatter)formatter).SupportedMediaTypes.Add(
                            Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("text/plain"));
                }
            }).AddJsonOptions(options =>
            {
                options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
            });

You can use os.listdir for this purpose. If you only want files and not directories, you can filter the results using os.path.isfile.

example:

files = os.listdir(os.curdir)  #files and directories

or

files = filter(os.path.isfile, os.listdir( os.curdir ) )  # files only
files = [ f for f in os.listdir( os.curdir ) if os.path.isfile(f) ] #list comprehension version.

For those who are working with Bootstrap-select, you might want to use this:

$('#mySelect').selectpicker('render');

package com.programmingfree.springshop.controller;

import java.util.List;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.programmingfree.springshop.dao.UserShop;
import com.programmingfree.springshop.domain.User;


@RestController
@RequestMapping("/shop/user")
public class SpringShopController {

 UserShop userShop=new UserShop();

 @RequestMapping(value = "/{id}", method = RequestMethod.GET,headers="Accept=application/json")
 public User getUser(@PathVariable int id) {
  User user=userShop.getUserById(id);
  return user;
 }


 @RequestMapping(method = RequestMethod.GET,headers="Accept=application/json")
 public List<User> getAllUsers() {
  List<User> users=userShop.getAllUsers();
  return users;
 }


}

In the above example they going to display all user and particular id details now I want to use both id and name,

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

now I want to use both id and name

localhost:8093/plejson/shop/user/11/raju <-----------------like this it means we can use any one in this please help me out.....

Use this:

window.open('', '_self');

This only works in chrome; it is a bug. It will be fixed in the future, so use this hacky solution with this in mind.

This function gives all 4 limits of the used range:

Function FindUsedRangeLimits()
    Set Sheet = ActiveSheet
    Sheet.UsedRange.Select

    ' Display the range's rows and columns.
    row_min = Sheet.UsedRange.Row
    row_max = row_min + Sheet.UsedRange.Rows.Count - 1
    col_min = Sheet.UsedRange.Column
    col_max = col_min + Sheet.UsedRange.Columns.Count - 1

    MsgBox "Rows " & row_min & " - " & row_max & vbCrLf & _
           "Columns: " & col_min & " - " & col_max
    LastCellBeforeBlankInColumn = True
End Function

You could use this to pick all li elements without class:

$('ul#list li:not([class])')

use Hibernate.initialize for lazy field

Another way to see the same problem. Hope helpfull

I'm using Android Studio 0.5.2. So if your version is lower than mine my answer may not work for you.

3 ways to add a new Jar to your project:

1. Menu under Files-->Project Structure
2. Just press 'F4'
3. under Project navigation, right clink on any java library and a context menu will show then click on 'Open Library Settings'

A Project Structure window will popup.

On the left column click on 'Libraries' then look at the right pane where there is a plus sign '+' and click on it then enter the path to your new library.

Make sure the new library is under the 'project\libs\' folder otherwise you may get a broken link when you save your project source code.

You can't remove anything from an array - they're always fixed length. Once you've created an array of length 3, that array will always have length 3.

You'd be better off with a List<String>, e.g. an ArrayList<String>:

List<String> list = new ArrayList<String>();
list.add("google");
list.add("microsoft");
list.add("apple");
System.out.println(list.size()); // 3

list.remove("apple");
System.out.println(list.size()); // 2

Collections like this are generally much more flexible than working with arrays directly.

EDIT: For removal:

void removeRandomElement(List<?> list, Random random)
{
    int index = random.nextInt(list.size());
    list.remove(index);
}

You can use:

$ host -l domain.com

Under the hood, this uses the AXFR query mentioned above. You might not be allowed to do this though. In that case, you'll get a transfer failed message.

I have a very simple solution for this problem. You don't need to use the console.

TLDR: Create repo, move files to existing projects folder, SourceTree will ask you where his files are, locate the files. Done, your repo is in another folder.

Long answer:

1. Create your new repository on Bitbucket
2. Click "Clone in SourceTree"
3. Let the program put your new repo where it wants, in my case SourceTree created a new folder in My Documents.
4. Locate in windows explorer your new repository folder.
5. Cut the .hg and README (or anything else you find in that folder)
6. Paste it in the location where is your existing project
7. Return to SourceTree and it will say "Error encountered...", just click OK
8. On the left side you will have your repository but with red message: Repository Moved or Deleted. Click on that.
9. Now you will see Repository Missing popup. Click on Change Folder and locate your existing project folder where you have moved the files mentoned earlier.
10. Thats it!

Tips: Clone in SourceTree option is not available right after you create new repository so you first have to click on Create Readme File for that option to become available.

Just pass your regression model into the following function:

    plot_coeffs <- function(mlr_model) {
      coeffs <- coefficients(mlr_model)
      mp <- barplot(coeffs, col="#3F97D0", xaxt='n', main="Regression Coefficients")
      lablist <- names(coeffs)
      text(mp, par("usr")[3], labels = lablist, srt = 45, adj = c(1.1,1.1), xpd = TRUE, cex=0.6)
    }

Use as follows:

model <- lm(Petal.Width ~ ., data = iris)

plot_coeffs(model)

Here is a good article from Microsoft http://www.iis.net/learn/troubleshoot/security-issues/troubleshooting-forms-authentication that covers various cases and scenarios.

while IFS='=' read -r name value ; do
    # Print line if found variable
    sed -n '/${'"${name}"'}/p' docker-compose.yml
    # Replace variable with value. 
    sed -i 's|${'"${name}"'}|'"${value}"'|' docker-compose.yml
done < <(env)

Note: Variable name or value should not contain "|", because it is used as a delimiter.

For Visual Studio 2015 the MSBuild variables have changed a bit:

  <Target Name="SpicNSpan" AfterTargets="Clean"> <!-- common vars https://msdn.microsoft.com/en-us/library/c02as0cs.aspx?f=255&MSPPError=-2147217396 -->
         <RemoveDir Directories="$(TargetDir)" /> <!-- bin -->
         <RemoveDir Directories="$(SolutionDir).vs" /> <!-- .vs -->
         <RemoveDir Directories="$(ProjectDir)$(BaseIntermediateOutputPath)" /> <!-- obj -->
  </Target>

Notice that this snippet also wipes out the .vs folder from the root directory of your solution. You may want to comment out the associated line if you feel that removing the .vs folder is an overkill. I have it enabled because I noticed that in some third party projects it causes issues when files ala application.config exist inside the .vs folder.

Addendum:

If you are into optimizing the maintainability of your solutions you might want to take things one step further and place the above snippet into a separate file like so:

  <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
       <Target Name="SpicNSpan" AfterTargets="Clean"> <!-- common vars https://msdn.microsoft.com/en-us/library/c02as0cs.aspx?f=255&MSPPError=-2147217396 -->
            <RemoveDir Directories="$(TargetDir)" /> <!-- bin -->
            <RemoveDir Directories="$(SolutionDir).vs" /> <!-- .vs -->
            <RemoveDir Directories="$(ProjectDir)$(BaseIntermediateOutputPath)" /> <!-- obj -->
       </Target>
  </Project>

And then include this file at the very end of each and every one of your *.csproj files like so:

     [...]
     <Import Project="..\..\Tools\ExtraCleanup.targets"/>
  </Project>

This way you can enrich or fine-tune your extra-cleanup-logic centrally, in one place without going through the pains of manually editing each and every *.csproj file by hand every time you want to make an improvement.

ActiveRecord#where will return an ActiveRecord::Relation object (which will never be nil). Try using .empty? on the relation to test if it will return any records.

Create a foreground service with the START_STICKY flag.

@Override
public int onStartCommand(Intent startIntent, int flags, int startId) {
   if (startIntent != null) {
       String action = startIntent.getAction();
       String command = startIntent.getStringExtra(CMD_NAME);
       if (ACTION_CMD.equals(action)) {
           if (CMD_PAUSE.equals(command)) {
               if (mPlayback != null && mPlayback.isPlaying()) {
                   handlePauseRequest();
               }
           } else if (CMD_PLAY.equals(command)) {
               ArrayList<Track> queue = new ArrayList<>();
               for (Parcelable input : startIntent.getParcelableArrayListExtra(ARG_QUEUE)) {
                   queue.add((Track) Parcels.unwrap(input));
               }
               int index = startIntent.getIntExtra(ARG_INDEX, 0);
               playWithQueue(queue, index);
           }
       }
   }

   return START_STICKY;
}

This can then be called from any activity to play some music

Intent intent = new Intent(MusicService.ACTION_CMD, fileUrlToPlay, activity, MusicService::class.java)
intent.putParcelableArrayListExtra(MusicService.ARG_QUEUE, tracks)
intent.putExtra(MusicService.ARG_INDEX, position)
intent.putExtra(MusicService.CMD_NAME, MusicService.CMD_PLAY)
activity.startService(intent)

You can bind to the service using bindService and to make the Service pause/stop from the corresponding activity lifecycle methods.

Here's a good tutorial about Playing music in the background on Android

And it's maybe also handy to know that BigTable is not a relational database (like MySQL) but a huge (distributed) hash table which has very different characteristics. You can play around with (a limited version) of BigTable yourself on the Google AppEngine platform.

Next to Hadoop mentioned above there are many other implementations that try to solve the same problems as BigTable (scalability, availability). I saw a nice blog post yesterday listing most of them here.

There is a statement you can issue at the module level:

Option Compare Text

This makes all "text comparisons" case insensitive. This means the following code will show the message "this is true":

Option Compare Text

Sub testCase()
  If "UPPERcase" = "upperCASE" Then
    MsgBox "this is true: option Compare Text has been set!"
  End If
End Sub

See for example http://www.ozgrid.com/VBA/vba-case-sensitive.htm . I'm not sure it will completely solve the problem for all instances (such as the Application.Match function) but it will take care of all the if a=b statements. As for Application.Match - you may want to convert the arguments to either upper case or lower case using the LCase function.

Actually, For me below works fine.

@Component
public class MyBean {

   public static String prop;

   @Value("${some.prop}")
   public void setProp(String prop) {
      this.prop= prop;
   }

   public MyBean() {

   }

   @PostConstruct
   public void init() {
      System.out.println("================== " + prop + "================== ");
   }

}

Now whereever i want, just invoke

MyBean.prop

it will return value.

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

The main difference is: Web API is a service for any client, any devices, and MVC Controller only serve its client. The same because it is MVC platform.

var wrapper = $(document.body);

strings = [
    "19 51 2.108997",
    "20 47 2.1089"
];

$.each(strings, function(key, value) {
    var tmp = value.split(" ");
    $.each([
        tmp[0] + " " + tmp[1],
        tmp[2]
    ], function(key, value) {
        $("<span>" + value + "</span>").appendTo(wrapper);
    }); 
});

setState takes new state and optional callback function which is called after the state has been updated.

this.setState(
  {newState: 'whatever'},
  () => {/*do something after the state has been updated*/}
)

The following example displays several values that are formatted by using custom format strings that include zero placeholders.

String.Format("{0:N1}", 29255.0);

Or

29255.0.ToString("N1")

result "29,255.0"

String.Format("{0:N2}", 29255.0);

Or

29255.0.ToString("N2")

result "29,255.00"

Relying on the compiler vendor's implementation of primitive type sizes WILL come back to haunt you if you ever compile your code on another machine architecture, OS, or another vendor's compiler .

Most compiler vendors provide a header file that defines primitive types with explict type sizes. These primitive types should be used when ever code may be potentially ported to another compiler (read this as ALWAYS in EVERY instance). For example, most UNIX compilers have int8_t uint8_t int16_t int32_t uint32_t. Microsoft has INT8 UINT8 INT16 UINT16 INT32 UINT32. I prefer Borland/CodeGear's int8 uint8 int16 uint16 int32 uint32. These names also give a little reminder of the size/range of the intended value.

For years I have used Borland's explicit primitive type names and #include the following C/C++ header file (primitive.h) which is intended to define the explicit primitive types with these names for any C/C++ compiler (this header file might not actually cover every compiler but it covers several compilers I have used on Windows, UNIX and Linux, it also doesn't (yet) define 64bit types).

#ifndef primitiveH
#define primitiveH
// Header file primitive.h
// Primitive types
// For C and/or C++
// This header file is intended to define a set of primitive types
// that will always be the same number bytes on any operating operating systems
// and/or for several popular C/C++ compiler vendors.
// Currently the type definitions cover:
// Windows (16 or 32 bit)
// Linux
// UNIX (HP/US, Solaris)
// And the following compiler vendors
// Microsoft, Borland/Imprise/CodeGear, SunStudio,  HP/UX
// (maybe GNU C/C++)
// This does not currently include 64bit primitives.
#define float64 double
#define float32 float
// Some old C++ compilers didn't have bool type
// If your compiler does not have bool then add   emulate_bool
// to your command line -D option or defined macros.

If you want to do it from the command line and not built into the script itself, use:

.\myscript.ps1 | Out-File c:\output.csv

If you want to disable unreferenced local variable write in some header

template<class T>
void ignore (const T & ) {}

and use

catch(const Except & excpt) {
    ignore(excpt); // No warning
    // ...  
} 

Because you did not write a comparison operator for your struct. The compiler does not generate it for you, so if you want comparison, you have to write it yourself.

AvaloniaUI now has support for running on top of .NET Core on Windows, OS X, and Linux. XAML, bindings and control templates included.

E.g. to develop on macOS with Rider:

1. Follow instructions to install the Avalonia dotnet new templates
2. Open JetBrains Rider and from the Welcome screen,
3. Choose New Solution ? (near the top of the Templates List) ? More Templates ? Button Install Template...* ? browse to the directory where you cloned the templates at step 1.
4. Click the Reload Button
5. Behold! Avalonia Templates now appear in the New Solution Templates List!
6. Choose an Avalonia template
7. Build and run. See the GUI open before your eyes.

The problem is your "Project SDK" is none! Add a "Project SDK" by clicking "New ..." and choose the path of JDK. And then it should be OK.

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

I just discovered that the Mock library provides an assertRaisesWithMessage() method (in its unittest.TestCase subclass), which will check not only that the expected exception is raised, but also that it is raised with the expected message:

from testcase import TestCase

import mymod

class MyTestCase(TestCase):
    def test1(self):
        self.assertRaisesWithMessage(SomeCoolException,
                                     'expected message',
                                     mymod.myfunc)

How I fixed this issue was I manually changed the code behind (from the menu View/code). The section below should have as many number of pairs <TablixMember> </TablixMember> as the number of rows are in the tablix. In my case I had more pairs <TablixMember> </TablixMember>than the number of rows in the tablix. Also if you go to "Advanced mode" (to the right of "Column Groups") the number of static lines behind the "Row groups" should be equal to the number of rows in the tablix. The way to make it equal is changing the code.

<TablixRowHierarchy>
      <TablixMembers>
        <TablixMember>
          <KeepWithGroup>After</KeepWithGroup>
          <RepeatOnNewPage>true</RepeatOnNewPage>
        </TablixMember>
        <TablixMember>
          <Group Name="Detail" />
        </TablixMember>
      </TablixMembers>
    </TablixRowHierarchy>

If the indices match then:

df['B'] = df1['E']

should work otherwise:

df['B'] = df1['E'].values

will work so long as the length of the elements matches

One solution is to set tis widget color property to Colors.transparent. For instance:

IconButton(
    icon: Image.asset("myImage.png",
        color: Colors.transparent,
    ),
    onPressed: () {},
),

The final keyword is used to declare constants.

final int FILE_TYPE = 3;

The finally keyword is used in a try catch statement to specify a block of code to execute regardless of thrown exceptions.

try
{
  //stuff
}
catch(Exception e)
{
  //do stuff
}
finally
{
  //this is always run
}

And finally (haha), finalize im not entirely sure is a keyword, but there is a finalize() function in the Object class.

Nobody has mentioned GetPerformanceInfo yet. PInvoke signatures are available.

This function makes the following system-wide information available:

• CommitTotal
• CommitLimit
• CommitPeak
• PhysicalTotal
• PhysicalAvailable
• SystemCache
• KernelTotal
• KernelPaged
• KernelNonpaged
• PageSize
• HandleCount
• ProcessCount
• ThreadCount

PhysicalTotal is what the OP is looking for, although the value is the number of pages, so to convert to bytes, multiply by the PageSize value returned.

Because JSON has a string data type (which is practically anything between " and "). It does not have a data type that matches something

                .ifPresent(converter -> converter.addSupportedMediaTypes(MediaType.APPLICATION_FORM_URLENCODED_VALUE));
    }

}

As of Spark 2.0.0, you can do the following.

Case Class

Let's define a Person case class:

scala> case class Person(id: Int, name: String)
defined class Person

Import spark SparkSession implicit Encoders:

scala> import spark.implicits._
import spark.implicits._

And use SparkSession to create an empty Dataset[Person]:

scala> spark.emptyDataset[Person]
res0: org.apache.spark.sql.Dataset[Person] = [id: int, name: string]

Schema DSL

You could also use a Schema "DSL" (see Support functions for DataFrames in org.apache.spark.sql.ColumnName).

scala> val id = $"id".int
id: org.apache.spark.sql.types.StructField = StructField(id,IntegerType,true)

scala> val name = $"name".string
name: org.apache.spark.sql.types.StructField = StructField(name,StringType,true)

scala> import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructType

scala> val mySchema = StructType(id :: name :: Nil)
mySchema: org.apache.spark.sql.types.StructType = StructType(StructField(id,IntegerType,true), StructField(name,StringType,true))

scala> import org.apache.spark.sql.Row
import org.apache.spark.sql.Row

scala> val emptyDF = spark.createDataFrame(sc.emptyRDD[Row], mySchema)
emptyDF: org.apache.spark.sql.DataFrame = [id: int, name: string]

scala> emptyDF.printSchema
root
 |-- id: integer (nullable = true)
 |-- name: string (nullable = true)

Good cocoa function:

-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
   BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
   NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
   NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
   NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
   NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
   return [emailTest evaluateWithObject:checkString];
}

Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/

And because categories are just better, you could also add an interface:

@interface NSString (emailValidation) 
  - (BOOL)isValidEmail;
@end

Implement

@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
  BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
  NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
  NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
  NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
  NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
  return [emailTest evaluateWithObject:self];
}
@end

And then utilize:

if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }

The list method index will return -1 if the item is not present, and will return the index of the item in the list if it is present. Alternatively in an if statement you can do the following:

if myItem in list:
    #do things

You can also check if an element is not in a list with the following if statement:

if myItem not in list:
    #do things

For example 1 and 2 you need to create static methods:

public static string InstanceMethod() {return "Hello World";}

Then for example 3 you need an instance of your object to invoke the method:

object o = new object();
string s = o.InstanceMethod();

window.location = mypage.href is a direct command for the browser to dump it's contents and start loading up some more. So for better clarification, here's what's happening in your PHP script:

echo '<script type="text/javascript">'; 
echo 'alert("review your answer");'; 
echo 'window.location = "index.php";';
echo '</script>';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (albeit an older method of loading a new URL (AND NOTICE that there are no "\n" (new line) indicators between the lines and is therefore causing some havoc in the JS decoder.

Let me suggest that you do this another way..

echo '<script type="text/javascript">\n'; 
echo 'alert("review your answer");\n'; 
echo 'document.location.href = "index.php";\n';
echo '</script>\n';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (in a better fashion than before) And WOW - it all works because the JS decoder can see that each command is anow a new line.

Best of luck!

I implemented a horizontal/vertical search, (first make a div full of vertical line links arranged horizontally, then make a div full of horizontal line links arranged vertically, and simply see which one has the hover state) like Tim Down's idea above, and it works pretty fast. Sadly, does not work on Chrome 32 on KDE.

== and != do not take into account the data type of the variables you compare. So these would all return true:

'0'   == 0
false == 0
NULL  == false

=== and !== do take into account the data type. That means comparing a string to a boolean will never be true because they're of different types for example. These will all return false:

'0'   === 0
false === 0
NULL  === false

You should compare data types for functions that return values that could possibly be of ambiguous truthy/falsy value. A well-known example is strpos():

// This returns 0 because F exists as the first character, but as my above example,
// 0 could mean false, so using == or != would return an incorrect result
var_dump(strpos('Foo', 'F') != false);  // bool(false)
var_dump(strpos('Foo', 'F') !== false); // bool(true), it exists so false isn't returned

may its so late but the response useful for others so : Sometimes, when you don't specify a server or servlet container at the creation of the project, NetBeans fails to create a context.xml file.

1. In your project under Web Pages, create a folder called META-INF.

Do this by right mouse button clicking on Web pages, and select:

New->Other->Other->File Folder

Name the folder META-INF. Case is important, even on Windows.

1. Create a file called context.xml in the META-INF folder.

Do this by right mouse button clicking on the new META-INF folder, and select:

New->Other->XML->XML Document

Name it context (NetBeans adds the .xml) Select Well-formed Document Press Finish

1. Edit the new document (context.xml), and add the following:

   <?xml version="1.0" encoding="UTF-8"?> 
   <Context antiJARLocking="true" path="/app-name"/> 
   

Replace app-name with the name of your application.

Now your in-place deployment should work. If not, make sure that the file can be read by everyone.

The context.xml file is specific to Tomcat. For more information about that file, see the Tomcat documentation at tomcat.apache.org.

There are lots of great answers which discuss differences in the use cases for each function. None of the answer discuss the differences in performance. That is reasonable cause various functions expects various input and produces various output, yet most of them have a general common objective to evaluate by series/groups. My answer is going to focus on performance. Due to above the input creation from the vectors is included in the timing, also the apply function is not measured.

I have tested two different functions sum and length at once. Volume tested is 50M on input and 50K on output. I have also included two currently popular packages which were not widely used at the time when question was asked, data.table and dplyr. Both are definitely worth to look if you are aiming for good performance.

library(dplyr)
library(data.table)
set.seed(123)
n = 5e7
k = 5e5
x = runif(n)
grp = sample(k, n, TRUE)

timing = list()

# sapply
timing[["sapply"]] = system.time({
    lt = split(x, grp)
    r.sapply = sapply(lt, function(x) list(sum(x), length(x)), simplify = FALSE)
})

# lapply
timing[["lapply"]] = system.time({
    lt = split(x, grp)
    r.lapply = lapply(lt, function(x) list(sum(x), length(x)))
})

# tapply
timing[["tapply"]] = system.time(
    r.tapply <- tapply(x, list(grp), function(x) list(sum(x), length(x)))
)

# by
timing[["by"]] = system.time(
    r.by <- by(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# aggregate
timing[["aggregate"]] = system.time(
    r.aggregate <- aggregate(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# dplyr
timing[["dplyr"]] = system.time({
    df = data_frame(x, grp)
    r.dplyr = summarise(group_by(df, grp), sum(x), n())
})

# data.table
timing[["data.table"]] = system.time({
    dt = setnames(setDT(list(x, grp)), c("x","grp"))
    r.data.table = dt[, .(sum(x), .N), grp]
})

# all output size match to group count
sapply(list(sapply=r.sapply, lapply=r.lapply, tapply=r.tapply, by=r.by, aggregate=r.aggregate, dplyr=r.dplyr, data.table=r.data.table), 
       function(x) (if(is.data.frame(x)) nrow else length)(x)==k)
#    sapply     lapply     tapply         by  aggregate      dplyr data.table 
#      TRUE       TRUE       TRUE       TRUE       TRUE       TRUE       TRUE 

# print timings
as.data.table(sapply(timing, `[[`, "elapsed"), keep.rownames = TRUE
              )[,.(fun = V1, elapsed = V2)
                ][order(-elapsed)]
#          fun elapsed
#1:  aggregate 109.139
#2:         by  25.738
#3:      dplyr  18.978
#4:     tapply  17.006
#5:     lapply  11.524
#6:     sapply  11.326
#7: data.table   2.686

You need $event.currentTarget instead of $event.target.

you can simply use two table divs, for instance:

<div style="display:table; width:450px; margin:0 auto; margin-top:30px; ">_x000D_
  <div style="display:table-row">_x000D_
    <div style="width:50%">element1</div>_x000D_
    <div style="width:50%">element2</div>_x000D_
  </div>_x000D_
</div>_x000D_
<div style="display:table; width:450px; margin:0 auto;">_x000D_
  <div style="display:table-row">_x000D_
    <div style="width:100%">element1</div>_x000D_
  </div>_x000D_
</div>

works great!

Well, if you are not satisfied with the default setting, you can use ANSI escape code to help you set the color, and if you want to modify some text, you can write bash to help you. see as below:

Eaxmplae

# .gitconfig

[alias]
    st-color = "!f() { \
        echo -n -e '\\033[38;2;255;0;01m\\033[4m' ;\
        git status -s | grep ' D' | \
        sed -e 's/^ ./DELETE:/' ; \
        echo -n -e '\\033[m' ;\
        \
        echo -n -e '\\033[48;2;128;128;128m' ;\
        echo -n -e '\\033[38;2;0;255;01m' ;\
        git status -s | grep ' [AM]' | \
        sed -e 's/^ ./NEW OR MODIFY:/' ; \
        echo -n -e '\\033[m' ;\
        \
        echo -n -e '\\033[38;2;255;0;255m' ;\
        echo Rename ;\
        git status -s | grep 'R ' | \
        sed -e 's/^..//' ; \
        echo -n -e '\\033[m' ;\
    }; f"

demo

Explanation

1. you can write the long script on .gitconfig use the syntax as below:

   [alias]
       your-cmd = !f() { \
           \
       }; f"
   

2. echo -n -e (see more echo)

   • -n = Do not output a trailing newline.
   • -e Enable interpretation of the following backslash-escaped

3. \\033[38;2;255;0;0m\\033[4m (see more SGR parameters)

   • \\033[38;2;255;0;0m : 38 mean fore color. 255;0;0 = Red | r;g;b
   • \\033[4m : underline

4. grep : The grep command is used to search text.

5. sed -e 's/be_replace_string/new_string/' replace string to new string.

you can also use jquery for this

  var phoneNumber = 8882070980;
            var filter = /^((\+[1-9]{1,4}[ \-]*)|(\([0-9]{2,3}\)[ \-]*)|([0-9]{2,4})[ \-]*)*?[0-9]{3,4}?[ \-]*[0-9]{3,4}?$/;

            if (filter.test(phoneNumber)) {
              if(phoneNumber.length==10){
                   var validate = true;
              } else {
                  alert('Please put 10  digit mobile number');
                  var validate = false;
              }
            }
            else {
              alert('Not a valid number');
              var validate = false;
            }

         if(validate){
          //number is equal to 10 digit or number is not string 
          enter code here...
        }

From commons-lang3

org.apache.commons.lang3.text.WordUtils.capitalizeFully(String str)

This happens when a python extension (written in C) tries to access a memory beyond reach.

You can trace it in following ways.

• Add sys.settrace at the very first line of the code.

• Use gdb as described by Mark in this answer.. At the command prompt

  gdb python
  (gdb) run /path/to/script.py
  ## wait for segfault ##
  (gdb) backtrace
  ## stack trace of the c code
  

I got this issue resolved by removing non-desirable characters from the password for the connection. For example, I had these characters: <##% and it caused the problem (most probably hash tag was the root cause of the problem).

If you have direct access to the remote repo, you could always use:

git reset --soft HEAD^

This works since there is no attempt to modify the non-existent working directory. For more details please see the original answer:

How can I uncommit the last commit in a git bare repository?

The simple way to do that is by command

adb install example.apk

and if you want to target connect device you can add parameter " -d "

adb install -d example.apk

if you have more than one device/emulator connected you will get this error

adb: error: connect failed: more than one device/emulator - waiting for device - error: more than one device/emulator

to avoid that you can list all devices by below command

adb devices

you will get results like below

 C:\Windows\System32>adb devices 
 List of devices attached 
 a3b09hh3e    device 
 emulator-5334    device

chose one of these devices and add parameter to adb command as " -s a3b09hh3e " as below

adb -s a3b09a6e install  example.apk

also as a hint if the path of the apk long and have a spaces, just add it between double quotes like

adb -s a3b09a6e install  "c:\my apk location\here 123\example.apk"

Oracle SQL:

There is the "IN" Operator in Oracle SQL which can be used for that:

select 
    namet.customerfirstname, addrt.city, addrt.postalcode
from schemax.nametable namet
join schemax.addresstable addrt on addrt.adtid = namet.natadtid
where namet.customerfirstname in ('David', 'Moses', 'Robi'); 

Anonymous types are just regular types that are implicitly declared. They have little to do with dynamic.

Now, if you were to use an ExpandoObject and reference it through a dynamic variable, you could add or remove fields on the fly.

edit

Sure you can: just cast it to IDictionary<string, object>. Then you can use the indexer.

You use the same casting technique to iterate over the fields:

dynamic employee = new ExpandoObject();
employee.Name = "John Smith";
employee.Age = 33;

foreach (var property in (IDictionary<string, object>)employee)
{
    Console.WriteLine(property.Key + ": " + property.Value);
}
// This code example produces the following output:
// Name: John Smith
// Age: 33

The above code and more can be found by clicking on that link.

git reset HEAD <file1> <file2> ...

remove the specified files from the next commit

You may also consider the following solution:

let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
    return html + "<li>" + item + "</li>";
        }, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

I had a similar issue, and I wanted to use ":%s/old/new/g", but ended up using two commands:

:0
gu:$

You can also use Object Oriented Programming (OOP) instead of procedural programming:

$fiveDays = new DateInterval('P5D');
$today = new DateTime();
$fiveDaysAgo = $today->sub(fiveDays); // or ->add(fiveDays); to add 5 days

Or with just one line of code:

$fiveDaysAgo = (new DateTime())->sub(new DateInterval('P5D'));

It is probably not sorted at all and uses the order at which entries appear in the filesystem, i.e. the one you get when using ls -U. (At least on my machine this produces the same order as listing glob matches).

Problem

The upstream server is timing out and I don't what is happening.

Where to Look first before increasing read or write timeout if your server is connecting to a database

Server is connecting to a database and that connection is working just fine and within sane response time, and its not the one causing this delay in server response time.

make sure that connection state is not causing a cascading failure on your upstream

Then you can move to look at the read and write timeout configurations of the server and proxy.

From what I've gathered, here are some differences between the two:

• PhoneGap basically generates native wrappers for what are still web apps. It spits out a WhateverYourPlatformIs project, you build it, and deploy. If we're talking about the iPhone (which is where I spend my time), it doesn't seem much different from creating a web app launcher (a shortcut that gets its own Springboard icon, so you can launch it like (like) a native app). The "app" itself is still html/js/etc., and runs inside a hosted browser control. What PhoneGap provides beyond that is a bridge between JavaScript and native device APIs. So, you write JavaScript against PhoneGap APIs, and PhoneGap then makes the appropriate corresponding native call. In that respect, it is different from deploying a plain old web app.

• Titanium source gets compiled down to native bits. That is, your html/js/etc. aren't simply attached to a project and then hosted inside a web browser control - they're turned into native apps. That means, for example, that your app's interface will be composed of native UI components. There are ways of getting native look-and-feel without having a native app, but... well... what a nightmare that usually turns out to be.

The two are similar in that you write all your stuff using typical web technologies (html/js/css/blah blah blah), and that you get access to native functionality through custom JavaScript APIs.

But, again, PhoneGap apps (PhonGapps? I don't know... is that a stupid name? It's easier to say - I know that much) start their lives as web apps and end their lives as web apps. On the iPhone, your html/js/etc. is just executed inside a UIWebView control, and the PhoneGap JavaScript APIs your js calls are routed to native APIs.

Titanium apps become native apps - they're just developed using web dev tech.

What does this actually mean?

1. A Titanium app will look like a "real" app because, ultimately, it is a "real" app.

2. A PhoneGap app will look like a web app being hosted in a browser control because, ultimately, it is a web app being hosted in a browser control.

Which is right for you?

• If you want to write native apps using web dev skills, Titanium is your best bet.

• If you want to write an app using web dev skills that you could realistically deploy to multiple platforms (iPhone, Android, Blackberry, and whatever else they decide to include), and if you want access to a subset of native platform features (GPS, accelerometer, etc.) through a unified JavaScript API, PhoneGap is probably what you want.

You might be asking: Why would I want to write a PhoneGapp (I've decided to use the name) rather than a web app that's hosted on the web? Can't I still access some native device features that way, but also have the convenience of true web deployment rather than forcing the user to download my "native" app and install it?

The answer is: Because you can submit your PhoneGapp to the App Store and charge for it. You also get that launcher icon, which makes it harder for the user to forget about your app (I'm far more likely to forget about a bookmark than an app icon).

You could certainly charge for access to your web-hosted web app, but how many people are really going to go through the process to do that? With the App Store, I pick an app, tap the "Buy" button, enter a password, and I'm done. It installs. Seconds later, I'm using it. If I had to use someone else's one-off mobile web transaction interface, which likely means having to tap out my name, address, phone number, CC number, and other things I don't want to tap out, I almost certainly wouldn't go through with it. Also, I trust Apple - I'm confident Steve Jobs isn't going to log my info and then charge a bunch of naughty magazine subscriptions to my CC for kicks.

Anyway, except for the fact that web dev tech is involved, PhoneGap and Titanium are very different - to the point of being only superficially comparable.

I hate web apps, by the by, and if you read iTunes App Store reviews, users are pretty good at spotting them. I won't name any names, but I have a couple "apps" on my phone that look and run like garbage, and it's because they're web apps that are hosted inside UIWebView instances. If I wanted to use a web app, I'd open Safari and, you know, navigate to one. I bought an iPhone because I want things that are iPhone-y. I have no problem using, say, a snazzy Google web app inside Safari, but I'd feel cheated if Google just snuck a bookmark onto Springboard by presenting a web app as a native one.

Have to go now. My girlfriend has that could-you-please-stop-using-that-computer-for-three-seconds look on her face.

I have had a similar question and I was using signal:

import signal

def signal_handler(signal_number, frame):
    print "Proceed ..."

signal.signal(signal.SIGINT, signal_handler)
signal.pause()

So you register a handler for the signal SIGINT and pause waiting for any signal. Now from outside your program (e.g. in bash), you can run kill -2 <python_pid>, which will send signal 2 (i.e. SIGINT) to your python program. Your program will call your registered handler and proceed running.

You cannot put spaces around the = sign when you do:

export foo=bar

Remove the spaces you have and you should be good to go.

If you type:

export foo = bar

the shell will interpret that as a request to export three names: foo, = and bar. = isn't a valid variable name, so the command fails. The variable name, equals sign and it's value must not be separated by spaces for them to be processed as a simultaneous assignment and export.

rate_text.textProperty().addListener(new ChangeListener<String>() {

    @Override
    public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
        String s="";
        for(char c : newValue.toCharArray()){
            if(((int)c >= 48 && (int)c <= 57 || (int)c == 46)){
                s+=c;
            }
        }
        rate_text.setText(s);
    }
});

This works fine as it allows you to enter only integer value and decimal value (having ASCII code 46).

   @Html.TextBoxFor(model => model.IdUsuario, new { @Value = "" + User.Identity.GetUserId() + "", @disabled = "true" })

@disabled = "true"

Work very well

Add the maven repository outside the buildscript configuration block of your main build.gradle file as follows:

repositories {
        maven {
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
    }

Make sure that you add them after the following:

apply plugin: 'com.android.application'

From what I can see FOR XML (as posted earlier) is the only way to do it if you want to also select other columns (which I'd guess most would) as the OP does. Using COALESCE(@var... does not allow inclusion of other columns.

Update: Thanks to programmingsolutions.net there is a way to remove the "trailing" comma to. By making it into a leading comma and using the STUFF function of MSSQL you can replace the first character (leading comma) with an empty string as below:

stuff(
    (select ',' + Column 
     from Table
         inner where inner.Id = outer.Id 
     for xml path('')
), 1,1,'') as Values

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

How to solve this issue:

1. Install RootExplorer
2. Create new tmp folder on SD card
3. Long press on tmp folder, and select Link to this folder (last option in menu)
4. Go to /data/local/ and tap button CREATE LINK from bottom

The Syabru Nagios JMX plugin is meant to be used from Nagios, but doesn't require Nagios and is very convenient for command-line use:

Running nginx -t through your commandline will issue out a test and append the output with the filepath to the configuration file (with either an error or success message).

The best superuser role would be the root.The Syntax is:

use admin

db.createUser(
{
    user: "root",
    pwd: "password",
    roles: [ "root" ]
})

For more details look at built-in roles.

Hope this helps !!!

Not a for each exactly, but you can do nested SQL

SELECT 
    distinct a.ID, 
    a.col2, 
    (SELECT 
        SUM(b.size) 
    FROM 
        tableb b 
    WHERE 
        b.id = a.col3)
FROM
    tablea a

Form Post Action :

<form method="post" action="{{url('login')}}" accept-charset="UTF-8">

Change your Route : In Routes -> Web.php

Route::post('login','WelcomeController@log_in');

You can do it faster without any imports just by using magics:

%env CUDA_DEVICE_ORDER=PCI_BUS_ID
%env CUDA_VISIBLE_DEVICES=0

Notice that all env variable are strings, so no need to use ". You can verify that env-variable is set up by running: %env <name_of_var>. Or check all of them with %env.

EDIT: This is bad advice. Use "o", as above. "s" does the wrong thing.

I always use this:

dateTime.ToUniversalTime().ToString("s");

This is correct if your schema looks like this:

<xs:element name="startdate" type="xs:dateTime"/>

Which would result in:

<startdate>2002-05-30T09:00:00</startdate>

The Mach-O object file format used by Mac OS X for executables and libraries distinguishes between shared libraries and dynamically loaded modules. Use otool -hv some_file to see the filetype of some_file.

Mach-O shared libraries have the file type MH_DYLIB and carry the extension .dylib. They can be linked against with the usual static linker flags, e.g. -lfoo for libfoo.dylib. They can be created by passing the -dynamiclib flag to the compiler. (-fPIC is the default and needn't be specified.)

Loadable modules are called "bundles" in Mach-O speak. They have the file type MH_BUNDLE. They can carry any extension; the extension .bundle is recommended by Apple, but most ported software uses .so for the sake of compatibility. Typically, you'll use bundles for plug-ins that extend an application; in such situations, the bundle will link against the application binary to gain access to the application’s exported API. They can be created by passing the -bundle flag to the compiler.

Both dylibs and bundles can be dynamically loaded using the dl APIs (e.g. dlopen, dlclose). It is not possible to link against bundles as if they were shared libraries. However, it is possible that a bundle is linked against real shared libraries; those will be loaded automatically when the bundle is loaded.

Historically, the differences were more significant. In Mac OS X 10.0, there was no way to dynamically load libraries. A set of dyld APIs (e.g. NSCreateObjectFileImageFromFile, NSLinkModule) were introduced with 10.1 to load and unload bundles, but they didn't work for dylibs. A dlopen compatibility library that worked with bundles was added in 10.3; in 10.4, dlopen was rewritten to be a native part of dyld and added support for loading (but not unloading) dylibs. Finally, 10.5 added support for using dlclose with dylibs and deprecated the dyld APIs.

On ELF systems like Linux, both use the same file format; any piece of shared code can be used as a library and for dynamic loading.

Finally, be aware that in Mac OS X, "bundle" can also refer to directories with a standardized structure that holds executable code and the resources used by that code. There is some conceptual overlap (particularly with "loadable bundles" like plugins, which generally contain executable code in the form of a Mach-O bundle), but they shouldn't be confused with Mach-O bundles discussed above.

It happens to me sometimes, I always fixed that with "mvn eclipse:clean" command to clean old properties and then run mvn eclipse:eclipse -Dwtpversion=2.0 (for web project of course). There are some old properties saved so eclipse is confused sometimes.

Another late answer, but if you're just trying to see if a new file has been uploaded to a file field, try this: (adapted from Christopher Adams's comment on the link http://zmsmith.com/2010/05/django-check-if-a-field-has-changed/ in zach's comment here)

Updated link: https://web.archive.org/web/20130101010327/http://zmsmith.com:80/2010/05/django-check-if-a-field-has-changed/

def save(self, *args, **kw):
    from django.core.files.uploadedfile import UploadedFile
    if hasattr(self.image, 'file') and isinstance(self.image.file, UploadedFile) :
        # Handle FileFields as special cases, because the uploaded filename could be
        # the same as the filename that's already there even though there may
        # be different file contents.

        # if a file was just uploaded, the storage model with be UploadedFile
        # Do new file stuff here
        pass

Additionally to

openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer
openssl pkcs12 -in domain.pfx -nocerts -nodes  -out domain.key

I also generated Certificate Authority (CA) certificate:

openssl pkcs12 -in domain.pfx -out domain-ca.crt -nodes -nokeys -cacerts

And included it in Apache config file:

<VirtualHost 192.168.0.1:443>

 SSLCertificateKeyFile /path/to/domain.key

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

You don't have to register an actual BroadcastReceiver as Android's BatteryManager is using a sticky Intent:

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

int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);

float batteryPct = level / (float)scale;

return (int)(batteryPct*100);

This is from the official docs over at https://developer.android.com/training/monitoring-device-state/battery-monitoring.html.

Could you do the following:

obj = {
    "1":"aa",
    "2":"bb"
};


var newNum = "3";
var newVal = "cc";


obj[newNum] = newVal;



alert(obj["3"]); // this would alert 'cc'

%s is for string %d is for decimal (or int) %c is for character

It appears to be chewing through an array of characters, and printing out whatever string exists starting at each subsequent position. The strings will stop at the first null in each case.

The commas are just separating the arguments to a function that takes a variable number of args; this number corresponds to the number of % args in the format descriptor at the front.

For OSX users:

If you use ls *.{mp3,exe,mp4}, it will throw an error if one of those extensions has no results.

Using ls *.(mp3|exe|mp4) will return all files matching those extensions, even if one of the extensions had 0 results.

If you are using an SMTP server on the same box and your SMTP is bound to an IP address instead of "Any Assigned" it may fail because it is trying to use an IP address (like 127.0.0.1) that SMTP is not currently working on.

I wanted to add, that in order to prevent it from being messed up in the first place you can type :set paste before pasting. After pasting, you can type :set nopaste for things like js-beautify and indenting to work again.

Stored procedures:

(+)

• Great flexibility
• Full control over SQL
• The highest performance available

(-)

• Requires knowledge of SQL
• Stored procedures are out of source control
• Substantial amount of "repeating yourself" while specifying the same table and field names. The high chance of breaking the application after renaming a DB entity and missing some references to it somewhere.
• Slow development

ORM:

(+)

• Rapid development
• Data access code now under source control
• You're isolated from changes in DB. If that happens you only need to update your model/mappings in one place.

(-)

• Performance may be worse
• No or little control over SQL the ORM produces (could be inefficient or worse buggy). Might need to intervene and replace it with custom stored procedures. That will render your code messy (some LINQ in code, some SQL in code and/or in the DB out of source control).
• As any abstraction can produce "high-level" developers having no idea how it works under the hood

The general tradeoff is between having a great flexibility and losing lots of time vs. being restricted in what you can do but having it done very quickly.

There is no general answer to this question. It's a matter of holy wars. Also depends on a project at hand and your needs. Pick up what works best for you.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

By default, when you are inside a function, you do not have access to the outer variables.

If you want your function to have access to an outer variable, you have to declare it as global, inside the function :

function someFuntion(){
    global $myArr;
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
}

For more informations, see Variable scope.

But note that using global variables is not a good practice : with this, your function is not independant anymore.

A better idea would be to make your function return the result :

function someFuntion(){
    $myArr = array();       // At first, you have an empty array
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;      // Put that $myVal into the array
    return $myArr;
}

And call the function like this :

$result = someFunction();

Your function could also take parameters, and even work on a parameter passed by reference :

function someFuntion(array & $myArr){
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;      // Put that $myVal into the array
}

Then, call the function like this :

$myArr = array( ... );
someFunction($myArr);  // The function will receive $myArr, and modify it

With this :

• Your function received the external array as a parameter
• And can modify it, as it's passed by reference.
• And it's better practice than using a global variable : your function is a unit, independant of any external code.

For more informations about that, you should read the Functions section of the PHP manual, and,, especially, the following sub-sections :

• Functions arguments
• Returning values

select distinct 'GRANT '||privilege||' ON '||OWNER||'.'||TABLE_NAME||' TO '||RP.GRANTEE
from DBA_ROLE_PRIVS RP join ROLE_TAB_PRIVS RTP 
on (RP.GRANTED_ROLE = RTP.role)  
where (OWNER in ('YOUR USER') --Change User Name
   OR RP.GRANTEE in ('YOUR USER')) --Change User Name
and RP.GRANTEE not in ('SYS', 'SYSTEM')
;

You can find the latest features of the .NET Framework 4.5 beta here

It breaks down the changes to the framework in the following categories:

• .NET for Metro style Apps
• Portable Class Libraries
• Core New Features and Improvements
• Parallel Computing
• Web
• Networking
• Windows Presentation Foundation (WPF)
• Windows Communication Foundation (WCF)
• Windows Workflow Foundation (WF)

You sound like you are more interested in the Web section as this shows the changes to ASP.NET 4.5. The rest of the changes can be found under the other headings.

You can also see some of the features that were new when the .NET Framework 4.0 was shipped here.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

try this

   function getmoviename(id)
   {    
     var p_url= yoururl from where you get movie name,
     jQuery.ajax({
     type: "GET",             
     url: p_url,
     data: "id=" + id,
      success: function(data) {
       $('#summary').html(data);

    }
 });    
 }

and you html part is

  <a href="javascript:void(0);" class="movie" onclick="getmoviename(youridvariable)">
  Name of movie</a>

  <div id="summary">Here is summary of movie</div>

#try this one:

tuples = list(zip(data_set["data_date"], data_set["data_1"],data_set["data_2"]))
print (tuples)

As you are looking for select permissions, I would suggest you to grant only select rather than all privileges. You can do this by:

GRANT SELECT ON <table> TO <role>;

Python 2

From the docs:

urllib.quote(string[, safe])

Replace special characters in string using the %xx escape. Letters, digits, and the characters '_.-' are never quoted. By default, this function is intended for quoting the path section of the URL.The optional safe parameter specifies additional characters that should not be quoted — its default value is '/'

That means passing '' for safe will solve your first issue:

>>> urllib.quote('/test')
'/test'
>>> urllib.quote('/test', safe='')
'%2Ftest'

About the second issue, there is a bug report about it here. Apparently it was fixed in python 3. You can workaround it by encoding as utf8 like this:

>>> query = urllib.quote(u"Müller".encode('utf8'))
>>> print urllib.unquote(query).decode('utf8')
Müller

By the way have a look at urlencode

Python 3

The same, except replace urllib.quote with urllib.parse.quote.

import gzip
import shutil
with gzip.open('file.txt.gz', 'rb') as f_in:
    with open('file.txt', 'wb') as f_out:
        shutil.copyfileobj(f_in, f_out)

you can also do it like that :

$ver = $em->getRepository('GedDocumentBundle:version')->search($val);

$tail = sizeof($ver);

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount() in a React class.

For you edit, you may want to try something like this:

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

Well, found a solution to my problem; Updating all rows using a SQL query and a SQL Task in SSIS Like Below. May help others if they face same challenge in future.

[EDIT] I made a mistake earlier, because, to get the text, you need to use .getText().toString().

Here is a full working example:

package com.psegina.passwordTest01;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.Toast;

public class Main extends Activity implements OnClickListener {
    LinearLayout l;
    EditText user;
    EditText pwd;
    Button btn;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        l = new LinearLayout(this);
        user = new EditText(this);
        pwd = new EditText(this);
        btn = new Button(this);

        l.addView(user);
        l.addView(pwd);
        l.addView(btn);
        btn.setOnClickListener(this);

        setContentView(l);
    }

    public void onClick(View v){
        String u = user.getText().toString();
        String p = pwd.getText().toString();
        if( u.equals( p ) )
            Toast.makeText(getApplicationContext(), "Matches", Toast.LENGTH_SHORT).show();
        else
            Toast.makeText(getApplicationContext(), user.getText()+" != "+pwd.getText(), Toast.LENGTH_SHORT).show();
    }
}

Original answer (Will not work because of the lack of toString())

Try using .getText() instead of .toString().

if( passw1.getText() == passw2.getText() )
#do something

.toString() returns a String representation of the whole object, meaning it won't return the text you entered in the field (see for yourself by adding a Toast which will show the output of .toString())

We can also validate it by below code

var a = new Date();
a.constructor === Date
/*
true
*/

If you don't want to actually navigate to a new page you can also have your anchor somewhere on the page like this.

<a id="the_anchor" href="">

And then to assign your string of JavaScript to the the onclick of the anchor, put this somewhere else (i.e. the header, later in the body, whatever):

<script>
    var js = "alert('I am your string of JavaScript');"; // js is your string of script
    document.getElementById('the_anchor').href = 'javascript:' + js;
</script>

If you have all of this info on the server before sending out the page, then you could also simply place the JavaScript directly in the href attribute of the anchor like so:

<a href="javascript:alert('I am your script.'); alert('So am I.');">Click me</a>

String newstring  = "";
String target2 = "fooBar";
newstring = target2.substring("foo".length()).trim();   
logger.debug("target2: {}",newstring); 
// output: target2: Bar
    
String target3 = "FooBar";
newstring = target3.substring("foo".length()).trim();
logger.debug("target3: {}",newstring); 
// output: target3: Bar

You must do the following command:

sort -n -k1 filename

That should do it :)

For a valid JSON string at least a "{}" is required. See more at the http://json.org/

You cant combine this to attributes.

But you can put both on one action method but you can encapsulate your logic into a other method and call this method from both actions.

The ActionName Attribute allows to have 2 ActionMethods with the same name.

[HttpGet]
public ActionResult MyMethod()
{
    return MyMethodHandler();
}

[HttpPost]
[ActionName("MyMethod")]
public ActionResult MyMethodPost()
{
    return MyMethodHandler();
}

private ActionResult MyMethodHandler()
{
    // handle the get or post request
    return View("MyMethod");
}

First install Ubuntu's python-lxml package and its dependencies:

sudo apt-get install python-lxml

Then use pip to upgrade to the latest version of lxml for Python:

pip install lxml

Ubuntu has the option to install a headless Java -- this means without graphics libraries. This wasn't always the case, but I encountered this while trying to run a Java text editor on 10.10 the other day. Run the following command to install a JDK that has these libraries:

sudo apt-get install openjdk-6-jdk

EDIT: Actually, looking at my config, you might need the JRE. If that's the case, run:

sudo apt-get install openjdk-6-jre

I have wrote this simple function for myself:

function sortObj(list, key) {
    function compare(a, b) {
        a = a[key];
        b = b[key];
        var type = (typeof(a) === 'string' ||
                    typeof(b) === 'string') ? 'string' : 'number';
        var result;
        if (type === 'string') result = a.localeCompare(b);
        else result = a - b;
        return result;
    }
    return list.sort(compare);
}

for example you have list of cars:

var cars= [{brand: 'audi', speed: 240}, {brand: 'fiat', speed: 190}];
var carsSortedByBrand = sortObj(cars, 'brand');
var carsSortedBySpeed = sortObj(cars, 'speed');

Keep() method marks the specified key in the dictionary for retention

You can use Keep() when prevent/hold the value depends on additional logic.

when you read TempData one’s and want to hold for another request then use keep method, so TempData can available for next request as above example.

If you have a good reason to set aside culture-dependent formatting and get explicit control over whether or not there's a space between the value and the "%", and whether the "%" is leading or trailing, you can use NumberFormatInfo's PercentPositivePattern and PercentNegativePattern properties.

For example, to get a decimal value with a trailing "%" and no space between the value and the "%":

myValue.ToString("P2", new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 });

More complete example:

using System.Globalization; 

...

decimal myValue = -0.123m;
NumberFormatInfo percentageFormat = new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 };
string formattedValue = myValue.ToString("P2", percentageFormat); // "-12.30%" (in en-us)

In my case the underlying system account through which the package was running was locked out. Once we got the system account unlocked and reran the package, it executed successfully. The developer said that he got to know of this while debugging wherein he directly tried to connect to the server and check the status of the connection.

Had the same problem.

Fixed by adding the dependency

classpath 'com.google.gms:google-services:3.0.0'

to the root build.gradle.

 super.onResume();
 getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

@Override public void onPause() {
 super.onPause();
 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

Please note that in the following I'm comparing the Select approach (the one that the OP wants to avoid), with the Range approach (and this is the answer to the question). So don't stop reading when you see the first Select.

It really depends on what you are trying to do. Anyway, a simple example could be useful. Let's suppose that you want to set the value of the active cell to "foo". Using ActiveCell you would write something like this:

Sub Macro1()
    ActiveCell.Value = "foo"
End Sub

If you want to use it for a cell that is not the active one, for instance for "B2", you should select it first, like this:

Sub Macro2()
    Range("B2").Select
    Macro1
End Sub

Using Ranges you can write a more generic macro that can be used to set the value of any cell you want to whatever you want:

Sub SetValue(cellAddress As String, aVal As Variant)
    Range(cellAddress).Value = aVal
End Sub

Then you can rewrite Macro2 as:

Sub Macro2()
    SetCellValue "B2", "foo"
End Sub

And Macro1 as:

Sub Macro1()
    SetValue ActiveCell.Address, "foo"
End Sub

I fixed this on my PC, on my environment iReport was iReport-5.1.0 , both jdk 7 and jdk 8 had been installed.

but iReport did not load

fix:- 1. Find the iReport.conf //C:\Program Files (x86)\Jaspersoft\iReport-5.1.0\etc

2. Open it on text editor

3. copy your jdk installation path //C:\Program Files (x86)\Java\jdk1.8.0_60

4. add jdkhome= into the ireport.conf file jdkhome="C:/Program Files (x86)/Java/jdk1.8.0_60"

Now iReport will work

I also don't under stand what the "-" means after the 200 140 section of the log

That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)

Well, it will take you forever. There is so much to learn about programming that 10 years are not enough.

http://norvig.com/21-days.html

Don't get me wrong, you will learn the basics quickly enough, but to become good at it will take much longer.

You should focus on an area and try to make some examples, if you choose web development, start with an hello world web page, then add some code to it. Learn about postbacks, viewstate and Sessions. Try to master ifs, cycles and functions, you really have a lot to cover, it's not easy to say "this is the best way to learn".

I guess in the end you will learn on a need to do basis.

For better understand how it works!

int n = JOptionPane.showConfirmDialog(null, "Yes No Cancel", "YesNoCancel", JOptionPane.YES_NO_CANCEL_OPTION);
    if(n == 0)
        {
        JOptionPane.showConfirmDialog(null, "You pressed YES\n"+"Pressed value is = "+n);
        }
    else if(n == 1)
        {
        JOptionPane.showConfirmDialog(null, "You pressed NO\n"+"Pressed value is = "+n);
        }
    else if (n == 2)
        {
        JOptionPane.showConfirmDialog(null, "You pressed CANCEL\n"+"Pressed value is = "+n);
        }
    else if (n == -1)
        {
        JOptionPane.showConfirmDialog(null, "You pressed X\n"+"Pressed value is = "+n);
        }

OR

int n = JOptionPane.showConfirmDialog(null, "Yes No Cancel", "YesNoCancel", JOptionPane.YES_NO_CANCEL_OPTION);
    switch (n) {
        case 0:
            JOptionPane.showConfirmDialog(null, "You pressed YES\n"+"Pressed value is = "+n);
            break;
        case 1:
            JOptionPane.showConfirmDialog(null, "You pressed NO\n"+"Pressed value is = "+n);
            break;
        case 2:
            JOptionPane.showConfirmDialog(null, "You pressed CANCEL\n"+"Pressed value is = "+n);
            break;
        case -1:
            JOptionPane.showConfirmDialog(null, "You pressed X\n"+"Pressed value is = "+n);
            break;
        default:
            break;
    }

The concept is very well explained by the accepted answer, but I find that the more example one sees, the better it sinks in. Here's an incremental example:

1) Boss says "get me number of items we have in stock grouped by brand"

You say: "no problem"

SELECT 
      BRAND
      ,COUNT(ITEM_ID) 
FROM 
      ITEMS
GROUP BY 
      BRAND;

Result:

+--------------+---------------+
|  Brand       |   Count       | 
+--------------+---------------+
| H&M          |     50        |
+--------------+---------------+
| Hugo Boss    |     100       |
+--------------+---------------+
| No brand     |     22        |
+--------------+---------------+

2) The boss says "Now get me a list of all items, with their brand AND number of items that the respective brand has"

You may try:

 SELECT 
      ITEM_NR
      ,BRAND
      ,COUNT(ITEM_ID) 
 FROM 
      ITEMS
 GROUP BY 
      BRAND;

But you get:

ORA-00979: not a GROUP BY expression 

This is where the OVER (PARTITION BY BRAND) comes in:

 SELECT 
      ITEM_NR
      ,BRAND
      ,COUNT(ITEM_ID) OVER (PARTITION BY BRAND) 
 FROM 
      ITEMS;

Whic means:

• COUNT(ITEM_ID) - get the number of items
• OVER - Over the set of rows
• (PARTITION BY BRAND) - that have the same brand

And the result is:

+--------------+---------------+----------+
|  Items       |  Brand        | Count()  |
+--------------+---------------+----------+
|  Item 1      |  Hugo Boss    |   100    | 
+--------------+---------------+----------+
|  Item 2      |  Hugo Boss    |   100    | 
+--------------+---------------+----------+
|  Item 3      |  No brand     |   22     | 
+--------------+---------------+----------+
|  Item 4      |  No brand     |   22     | 
+--------------+---------------+----------+
|  Item 5      |  H&M          |   50     | 
+--------------+---------------+----------+

etc...

Setting the minSdkVersion to 21 from 19 solved the issue for me.

defaultConfig {
        applicationId "com.example"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 23
        versionName "1.0"
        vectorDrawables.useSupportLibrary = true
    }

Depends what it does. If your app takes up too much memory, or makes calls to functions/classes it shouldn't, SpringBoard may terminate it. However, it will most likely be rejected by Apple, as it does not follow their 7 background uses.

Another simple way is to use the pivot function to format the data as you need first.

df.plot() does the rest

df = pd.DataFrame([
    ['red', 0, 0],
    ['red', 1, 1],
    ['red', 2, 2],
    ['red', 3, 3],
    ['red', 4, 4],
    ['red', 5, 5],
    ['red', 6, 6],
    ['red', 7, 7],
    ['red', 8, 8],
    ['red', 9, 9],
    ['blue', 0, 0],
    ['blue', 1, 1],
    ['blue', 2, 4],
    ['blue', 3, 9],
    ['blue', 4, 16],
    ['blue', 5, 25],
    ['blue', 6, 36],
    ['blue', 7, 49],
    ['blue', 8, 64],
    ['blue', 9, 81],
], columns=['color', 'x', 'y'])

df = df.pivot(index='x', columns='color', values='y')

df.plot()

pivot effectively turns the data into:

PHP has a date_diff() function to do this.

A small addition to KTC's very informative main answer:

If you are using the free Visual Studio c++ 2010 Express, and managed to get that one to compile 64-bits binaries, and now want to use that to use a 64-bits version of the Boost libaries, you may end up with 32-bits libraries (your mileage may vary of course, but on my machine this is the sad case).

I could fix this using the following: inbetween the steps described above as

1. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
2. Run: bootstrap

I inserted a call to 'setenv' to set the environment. For a release build, the above steps become:

1. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
2. Run: "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\setenv.cmd" /Release /x64
3. Run: bootstrap

I found this info here: http://boost.2283326.n4.nabble.com/64-bit-with-VS-Express-again-td3044258.html

Code:

if [[ -e $1 && ! -e $2 ]]; then
   mkdir --parents --verbose -- "$(dirname -- "$2")"
fi
mv --verbose -- "$1" "$2"

Example:

arguments: "d1" "d2/sub"

mkdir: created directory 'd2'
renamed 'd1' -> 'd2/sub'

Make sure your app_offline.htm file is at least 512 bytes long. A zero-byte app_offline.htm will have no effect.

UPDATE: Newer versions of ASP.NET/IIS may behave better than when I first wrote this.

UPDATE 2: If you are using ASP.NET MVC, add the following to web.config:

<?xml version="1.0"?>
<configuration>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true" />
    </system.webServer>
</configuration>

In HTML only:

<label>
  <input type="file" name="input-name" style="display: none;" />
  <span>Select file</span>
</label>

Edit: I hadn't tested this in Blink, it actually doesn't work with a <button>, but it should work with most other elements–at least in recent browsers.

Check this fiddle with the code above.

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

You can use the ?? operator to set the default value but first you must set the Nullable property to true in your dbml file in the required field (xx.Online)

var hht = from x in db.HandheldAssets
        join a in db.HandheldDevInfos on x.AssetID equals a.DevName into DevInfo
        from aa in DevInfo.DefaultIfEmpty()
        select new
        {
        AssetID = x.AssetID,
        Status = xx.Online ?? false
        };

Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.

Connect as PCT account in the database, then grant the account you are using select access for the table.

grant select on pi_int to Account_used_to_connect

For every client you need to start separate thread. Example:

public class ThreadedEchoServer {

    static final int PORT = 1978;

    public static void main(String args[]) {
        ServerSocket serverSocket = null;
        Socket socket = null;

        try {
            serverSocket = new ServerSocket(PORT);
        } catch (IOException e) {
            e.printStackTrace();

        }
        while (true) {
            try {
                socket = serverSocket.accept();
            } catch (IOException e) {
                System.out.println("I/O error: " + e);
            }
            // new thread for a client
            new EchoThread(socket).start();
        }
    }
}

and

public class EchoThread extends Thread {
    protected Socket socket;

    public EchoThread(Socket clientSocket) {
        this.socket = clientSocket;
    }

    public void run() {
        InputStream inp = null;
        BufferedReader brinp = null;
        DataOutputStream out = null;
        try {
            inp = socket.getInputStream();
            brinp = new BufferedReader(new InputStreamReader(inp));
            out = new DataOutputStream(socket.getOutputStream());
        } catch (IOException e) {
            return;
        }
        String line;
        while (true) {
            try {
                line = brinp.readLine();
                if ((line == null) || line.equalsIgnoreCase("QUIT")) {
                    socket.close();
                    return;
                } else {
                    out.writeBytes(line + "\n\r");
                    out.flush();
                }
            } catch (IOException e) {
                e.printStackTrace();
                return;
            }
        }
    }
}

You can also go with more advanced solution, that uses NIO selectors, so you will not have to create thread for every client, but that's a bit more complicated.
