I upgraded from 2010 to 2013 and after changing all the projects' Platform Toolset, I need to right-click on the Solution and choose Retarget... to make it work.

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

I came here looking for a possible explanation before taking a closer look at the lines preceding the linker error. It turned out to have been an additional executable for which the global declaration was missing!

If You are comparing only with the date vale, then converting it to date (not datetime) will work

select id,numbers_from,created_date,amount_numbers,SMS_text 
 from Test_Table
 where 
 created_date <= convert(date,'2013-04-12',102)

This conversion is also applicable during using GetDate() function

You can just pass a list of the two points you want to connect to plt.plot. To make this easily expandable to as many points as you want, you could define a function like so.

import matplotlib.pyplot as plt

x=[-1 ,0.5 ,1,-0.5]
y=[ 0.5,  1, -0.5, -1]

plt.plot(x,y, 'ro')

def connectpoints(x,y,p1,p2):
    x1, x2 = x[p1], x[p2]
    y1, y2 = y[p1], y[p2]
    plt.plot([x1,x2],[y1,y2],'k-')

connectpoints(x,y,0,1)
connectpoints(x,y,2,3)

plt.axis('equal')
plt.show()

Note, that function is a general function that can connect any two points in your list together.

To expand this to 2N points, assuming you always connect point i to point i+1, we can just put it in a for loop:

import numpy as np
for i in np.arange(0,len(x),2):
    connectpoints(x,y,i,i+1)

In that case of always connecting point i to point i+1, you could simply do:

for i in np.arange(0,len(x),2):
    plt.plot(x[i:i+2],y[i:i+2],'k-')

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

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

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

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

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

Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.

This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/

Basically what I did was:

1. Downloaded from https://wkhtmltopdf.org/downloads.html
2. Unzipped the DEB file.
3. Unzipped data.tar.xz
4. Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)

Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.

you can use this

List<Car> requiredCars = cars.stream()
    .filter (t->  t!= null && StringUtils.startsWith(t.getName(),"M"))
    .collect(Collectors.toList());

I use:

from pathlib import Path
import platform
import tempfile

tempdir = Path("/tmp" if platform.system() == "Darwin" else tempfile.gettempdir())

This is because on MacOS, i.e. Darwin, tempfile.gettempdir() and os.getenv('TMPDIR') return a value such as '/var/folders/nj/269977hs0_96bttwj2gs_jhhp48z54/T'; it is one that I do not always want.

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

If the other answers don't work you can check if something else is using the port with netstat:

netstat -ano | findstr <your port number>

If nothing is already using it, the port might be excluded, try this command to see if the range is blocked by something else:

netsh interface ipv4 show excludedportrange protocol=tcp

I used a really simple loop to solve this in a BlackJack game I'm writing in HTML5 using the Isogenic Game Engine. You can see a video of the BlackJack game which shows the chips that were used to make up a bet from the bet value on the BlackJack table above the cards: http://bit.ly/yUF6iw

In this example, betValue equals the total value that you wish to divide into "coins" or "chips" or whatever.

You can set the chipValues array items to whatever your coins or chips are worth. Make sure that the items are ordered from lowest value to highest value (penny, nickel, dime, quarter).

Here is the JavaScript:

// Set the total that we want to divide into chips
var betValue = 191;

// Set the chip values
var chipValues = [
    1,
    5,
    10,
    25
];

// Work out how many of each chip is required to make up the bet value
var tempBet = betValue;
var tempChips = [];
for (var i = chipValues.length - 1; i >= 0; i--) {
    var chipValue = chipValues[i];
    var divided = Math.floor(tempBet / chipValue);

    if (divided >= 1) {
        tempChips[i] = divided;
        tempBet -= divided * chipValues[i];
    }

    if (tempBet == 0) { break; }
}

// Display the chips and how many of each make up the betValue
for (var i in tempChips) {
    console.log(tempChips[i] + ' of ' + chipValues[i]);
}

You obviously don't need to do the last loop and it is only there to console.log the final array values.

Using the newish java.util.concurrent.TimeUnit class you can do it like this

Date oldDate = new Date(); // oldDate == current time
Date newDate = new Date(oldDate.getTime() + TimeUnit.HOURS.toMillis(2)); // Add 2 hours

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

even this will work:

<div class="container">
            <div class="row">
                <div class="col-4 col-sm-4 col-md-6 order-1">
                    1
                </div>
                <div class="col-4 col-sm-4  col-md-6 order-3">
                    2
                </div>
                <div class="col-4 col-sm-4  col-md-12 order-2">
                    3
                </div>
            </div>
          </div>

I am adding to Matt Brunell's answer.

            string[] directories = myStringWithLotsOfFolders.Split(Path.DirectorySeparatorChar);

            string previousEntry = string.Empty;
            if (null != directories)
            {
                foreach (string direc in directories)
                {
                    string newEntry = previousEntry + Path.DirectorySeparatorChar + direc;
                    if (!string.IsNullOrEmpty(newEntry))
                    {
                        if (!newEntry.Equals(Convert.ToString(Path.DirectorySeparatorChar), StringComparison.OrdinalIgnoreCase))
                        {
                            Console.WriteLine(newEntry);
                            previousEntry = newEntry;
                        }
                    }
                }
            }

This should give you:

"\server"

"\server\folderName1"

"\server\folderName1\another name"

"\server\folderName1\another name\something"

"\server\folderName1\another name\something\another folder\"

(or sort your resulting collection by the string.Length of each value.

used for kolin in android for hide status bar in kolin no need to used semicolon(;) at the end of the line

window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

in android using java language for hid status bar

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

I think this works, at least partially (have not investigated): nvm uninstall <VERSION_TO_UNINSTALL> eg:

nvm uninstall 4.4.5

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

private void replaceView(View oldV,View newV){
        ViewGroup par = (ViewGroup)oldV.getParent();
        if(par == null){return;}
        int i1 = par.indexOfChild(oldV);
        par.removeViewAt(i1);
        par.addView(newV,i1);
    }

Since this is a question you come along on google using jquery tagname first child as a query I'll post another example:

<div><p>Some text, whatever</p></div>

$('div').children(':first-child').get(0).tagName); // ...and not $('div:first-child')[...]

The jquery result is an (uppercase) tagname: P

You should change your code to make use of SqlParameters and adapt your insert statement to the following

string connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// [ ] required as your fields contain spaces!!
string insStmt = "insert into Main ([First Name], [Last Name]) values (@firstName,@lastName)";

using (SqlConnection cnn = new SqlConnection(connetionString))
{
    cnn.Open();
    SqlCommand insCmd = new SqlCommand(insStmt, cnn);
    // use sqlParameters to prevent sql injection!
    insCmd.Parameters.AddWithValue("@firstName", textbox2.Text);
    insCmd.Parameters.AddWithValue("@lastName", textbox3.Text);
    int affectedRows = insCmd.ExecuteNonQuery();
    MessageBox.Show (affectedRows + " rows inserted!");
}

Since there is no restriction on bugs..

int i=1; int main() { int j=i/(i-1001); printf("%d\n", i++); main(); }

Or even better(?),

#include <stdlib.h>
#include <signal.h>

int i=1;
int foo() { int j=i/(i-1001); printf("%d\n", i++); foo(); }

int main()
{
        signal(SIGFPE, exit);
        foo();
}

My issue occurs when I add a PC to a domain. Restarting the service, making sure it's running, that it has the correct credentials to run, etc, as in other answers doesn't work. I don't know exactly what the problem is, but I can't even log in with the local user anymore to give the domain user access. Here's the steps that work for me:

In SSMS

• View > Registered Servers
• Database Engine > Local Server Groups > right-click pcname\sqlexpress
• Delete > Yes
• Right-click Local Server Groups > Tasks > Register Local Servers
• It confirms that it re-registered. pcname\sqlexpress reappears.

I'm then able to log in with the local windows auth'd user again, my databases are all there and everything. I then go about my business adding the domain user to Security > Logins.

INSERT syntax cannot have WHERE but you can use UPDATE.

The syntax is as follows:

UPDATE table_name

SET column1 = value1, column2 = value2, ...

WHERE condition;

If you don't want to alter the CSS file, this is what works for me. In HTML, add style with color:

<i class="fa fa-cog" style="color:#fff;"></i>

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

For Laravel 8 you can also use

Route::redirect('/here', '/there');
//or
Route::permanentRedirect('/here', '/there');

This also works with external URLs

Will the conditions be ORed or ANDed together?

Starts with: abc
Ends with: xyz
Contains: 123
Doesn't contain: 456

The OR version is fairly simple; as you said, it's mostly a matter of inserting pipes between individual conditions. The regex simply stops looking for a match as soon as one of the alternatives matches.

/^abc|xyz$|123|^(?:(?!456).)*$/

That fourth alternative may look bizarre, but that's how you express "doesn't contain" in a regex. By the way, the order of the alternatives doesn't matter; this is effectively the same regex:

/xyz$|^(?:(?!456).)*$|123|^abc/

The AND version is more complicated. After each individual regex matches, the match position has to be reset to zero so the next regex has access to the whole input. That means all of the conditions have to be expressed as lookaheads (technically, one of them doesn't have to be a lookahead, I think it expresses the intent more clearly this way). A final .*$ consummates the match.

/^(?=^abc)(?=.*xyz$)(?=.*123)(?=^(?:(?!456).)*$).*$/

And then there's the possibility of combined AND and OR conditions--that's where the real fun starts. :D

I've had this same problem for a while as I generate a fair number of ad-hoc reports from SQL Server and copy/paste them into Excel. I would also welcome a proper solution but my temporary workaround was to create a default macro in Excel which converts highlighted cells to Excel's datetime format, and assigned it to a hotkey (Shift-Ctrl-D in my case). So I open Excel, copy/paste from SSMS into a new Excel worksheet, highlight the column to convert and press Shift-Ctrl-D. Job done.

The .map function is only available on array.
It looks like data isn't in the format you are expecting it to be (it is {} but you are expecting []).

this.setState({data: data});

should be

this.setState({data: data.conversations});

Check what type "data" is being set to, and make sure that it is an array.

Modified code with a few recommendations (propType validation and clearInterval):

var converter = new Showdown.converter();

var Conversation = React.createClass({
  render: function() {
    var rawMarkup = converter.makeHtml(this.props.children.toString());
    return (
      <div className="conversation panel panel-default">
        <div className="panel-heading">
          <h3 className="panel-title">
            {this.props.id}
            {this.props.last_message_snippet}
            {this.props.other_user_id}
          </h3>
        </div>
        <div className="panel-body">
          <span dangerouslySetInnerHTML={{__html: rawMarkup}} />
        </div>
      </div>
    );
  }
});

var ConversationList = React.createClass({
 // Make sure this.props.data is an array
  propTypes: {
    data: React.PropTypes.array.isRequired
  },
  render: function() {

    window.foo            = this.props.data;
    var conversationNodes = this.props.data.map(function(conversation, index) {

      return (
        <Conversation id={conversation.id} key={index}>
          last_message_snippet={conversation.last_message_snippet}
          other_user_id={conversation.other_user_id}
        </Conversation>
      );
    });

    return (
      <div className="conversationList">
        {conversationNodes}
      </div>
    );
  }
});

var ConversationBox = React.createClass({
  loadConversationsFromServer: function() {
    return $.ajax({
      url: this.props.url,
      dataType: 'json',
      success: function(data) {
        this.setState({data: data.conversations});
      }.bind(this),
      error: function(xhr, status, err) {
        console.error(this.props.url, status, err.toString());
      }.bind(this)
    });
  },
  getInitialState: function() {
    return {data: []};
  },

  render: function() {
    return (

    );
  }
})

Clear backstack without loops

String name = getSupportFragmentManager().getBackStackEntryAt(0).getName();
getSupportFragmentManager().popBackStack(name, FragmentManager.POP_BACK_STACK_INCLUSIVE);

Where name is the addToBackStack() parameter

getSupportFragmentManager().beginTransaction().
                .replace(R.id.container, fragments.get(titleCode))
                .addToBackStack(name)

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

Stripes : pretty good. a book on this has come out from pragmatic programmers : http://www.pragprog.com/titles/fdstr/stripes. No XML. Requires java 1.5 or later.

tapestry : have tried an old version 3.x. I'm told that the current version 5.x is in Beta and pretty good.

Stripes should be the better in terms of taking care of maven, no xml and wrapping your head around fast.

You could do -

DELIMITER = '\t'
lines = list()
for line in open('file.txt'):
    lines.append(line.strip().split(DELIMITER))

The lines has got all the contents of your file.

One could also use list comprehensions to make this more compact.

lines = [ line.strip().split(DELIMITER) for line in open('file.txt')]

The short answer is the iPhone supports H.264 video, High profile and AAC audio, in container formats .mov, .mp4, or MPEG Segment .ts. MPEG Segment files are used for HTTP Live Streaming.

• For maximum compatibility with Android and desktop browsers, use H.264 + AAC in an .mp4 container.
• For extended length videos longer than 10 minutes you must use HTTP Live Streaming, which is H.264 + AAC in a series of small .ts container files (see App Store Review Guidelines rule 2.5.7).

Video

On the iPhone, H.264 is the only game in town. [1]

There are several different feature tiers or "profiles" available in H.264. All modern iPhones (3GS and above) support the High profile. These profiles are basically three different levels of algorithm "tricks" used to compress the video. More tricks give better compression, but require more CPU or dedicated hardware to decode. This is a table that lists the differences between the different profiles.

[1] Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. This is expected to change at some point.

In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network.

The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they support

4K [3840x2160] video recording at 30 fps

1080p [1920x1080] HD video recording at 30 fps or 60 fps.

Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw.

However, streaming video is a different matter. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum.

The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Figure 3 in that document gives a table of recommended streaming parameters:

This table is from May 2016.

As you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. Of course this is just a recommendation and YMMV.

Audio

The question is about video, but that video generally has one or more audio tracks with it. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps.

Container

The audio and video tracks go inside a container. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The iPhone supports

1. QuickTime .mov,
2. MP4, and
3. MPEG-TS.

The .mov and .mp4 file formats are closely related (.mp4 is in fact based on .mov), however .mp4 is an ISO standard that has much wider support.

As noted above, you have to use MPEG-TS for videos longer than 10 minutes.

Some time ago I installed Valloric/YouCompleteMe and I find it really awesome. It provides you completion for file paths, function names, methods, variable names... Together with davidhalter/jedi-vim it makes vim great for python programming (the only thing missing now is a linter).

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

If you're just formatting a number, you can just provide the proper custom numeric format to make it a 3 digit string directly:

myString = 3.ToString("000");

Or, alternatively, use the standard D format string:

myString = 3.ToString("D3");

No need for regex. This will also remove tabs, newlines etc

var newstr = String.Join("",str.Where(c=>!char.IsWhiteSpace(c)));

WhiteSpace chars : 0009 , 000a , 000b , 000c , 000d , 0020 , 0085 , 00a0 , 1680 , 180e , 2000 , 2001 , 2002 , 2003 , 2004 , 2005 , 2006 , 2007 , 2008 , 2009 , 200a , 2028 , 2029 , 202f , 205f , 3000.

$record = '123';

$this->db->distinct();

$this->db->select('accessid');

$this->db->where('record', $record); 

$query = $this->db->get('accesslog');

then

$query->num_rows();

should go a long way towards it.

Instead of os.path.isfile, suggested by others, I suggest using os.path.exists, which checks for anything with that name, not just whether it is a regular file.

Thus:

if not os.path.exists(filename):
    file(filename, 'w').close()

Alternatively:

file(filename, 'w+').close()

The latter will create the file if it exists, but not otherwise. It will, however, fail if the file exists, but you don't have permission to write to it. That's why I prefer the first solution.

In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.

In case of entity framework FK in dependent must also be its PK so in your case you should use:

public class Boo
{
    [Key, ForeignKey("Foo")]
    public string BooId{get;set;}
    public Foo Foo{get;set;}
}

Or fluent mapping

modelBuilder.Entity<Foo>()
            .HasOptional(f => f.Boo)
            .WithRequired(s => s.Foo);

Use the JQuery Serialize function

http://docs.jquery.com/Ajax/serialize

Serialize is typically used to prepare user input data to be posted to a server. The serialized data is in a standard format that is compatible with almost all server side programming languages and frameworks.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

Just turn the LIKE around

SELECT * FROM customers
WHERE 'Robert Bob Smith III, PhD.' LIKE CONCAT('%',name,'%')

Make a bat file with the following in it:

copy /y C:\temp\log1k.txt C:\temp\log1k_copied.txt

However, I think there are issues if there are spaces in your directory names. Notice this was copied to the same directory, but that doesn't matter. If you want to see how it runs, make another bat file that calls the first and outputs to a log:

C:\temp\test.bat > C:\temp\test.log

(assuming the first bat file was called test.bat and was located in that directory)

these both are working nicely:

select round(<maxNumber>*rand())

FLOOR(RAND() * (<max> - <min> + 1)) + <min> // generates a number
between <min> and <max> inclusive.

Here's an article from MSDN on a guide for how to write text to a file:

http://msdn.microsoft.com/en-us/library/8bh11f1k.aspx

I'd start there, then post additional, more specific questions as you continue your development.

just add

android:gravity="bottom" android:paddingBottom="10dp"

change paddingBottom according to your size of edittext

You can set imageview in XML file like this :

<ImageView
    android:id="@+id/image1"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:src="@drawable/imagep1" />

and you can define image view in android java file like :

ImageView imageView = (ImageView) findViewById(R.id.imageViewId);

and set Image with drawable like :

imageView.setImageResource(R.drawable.imageFileId);

and set image with your memory folder like :

File file = new File(SupportedClass.getString("pbg"));
if (file.exists()) {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap selectDrawable = BitmapFactory.decodeFile(file.getAbsolutePath(), options);
        imageView.setImageBitmap(selectDrawable);
}
else
{
      Toast.makeText(getApplicationContext(), "File not Exist", Toast.LENGTH_SHORT).show();
}

dic = {"key 1":"value 1","key b":"value b"}

#print the keys:
for key in dic:
    print key

#print the values:
for value in dic.itervalues():
    print value

#print key and values
for key, value in dic.iteritems():
    print key, value

Note:In Python 3, dic.iteritems() was renamed as dic.items()

Without Mutate

Actually, all unshift/push and shift/pop mutate the origin array.

The unshift/push add an item to the existed array from begin/end and shift/pop remove an item from the beginning/end of an array.

But there are few ways to add items to an array without a mutation. the result is a new array, to add to the end of array use below code:

const originArray = ['one', 'two', 'three'];
const newItem = 4;

const newArray = originArray.concat(newItem); // ES5
const newArray2 = [...originArray, newItem]; // ES6+

To add to begin of original array use below code:

const originArray = ['one', 'two', 'three'];
const newItem = 0;

const newArray = (originArray.slice().reverse().concat(newItem)).reverse(); // ES5
const newArray2 = [newItem, ...originArray]; // ES6+

With the above way, you add to the beginning/end of an array without a mutation.

One thing you should know is $ prefix refers to an Angular Method, $$ prefixes refers to angular methods that you should avoid using.

below is an example template and its controllers, we'll explore how $broadcast/$on can help us achieve what we want.

<div ng-controller="FirstCtrl">
    <input ng-model="name"/> 
    <button ng-click="register()">Register </button>
</div>

<div ng-controller="SecondCtrl">
    Registered Name: <input ng-model="name"/> 
</div>

The controllers are

app.controller('FirstCtrl', function($scope){
    $scope.register = function(){

    }
});

app.controller('SecondCtrl', function($scope){

});

My question to you is how do you pass the name to the second controller when a user clicks register? You may come up with multiple solutions but the one we're going to use is using $broadcast and $on.

$broadcast vs $emit

Which should we use? $broadcast will channel down to all the children dom elements and $emit will channel the opposite direction to all the ancestor dom elements.

The best way to avoid deciding between $emit or $broadcast is to channel from the $rootScope and use $broadcast to all its children. Which makes our case much easier since our dom elements are siblings.

Adding $rootScope and lets $broadcast

app.controller('FirstCtrl', function($rootScope, $scope){
    $scope.register = function(){
        $rootScope.$broadcast('BOOM!', $scope.name)
    }
});

Note we added $rootScope and now we're using $broadcast(broadcastName, arguments). For broadcastName, we want to give it a unique name so we can catch that name in our secondCtrl. I've chosen BOOM! just for fun. The second arguments 'arguments' allows us to pass values to the listeners.

Receiving our broadcast

In our second controller, we need to set up code to listen to our broadcast

app.controller('SecondCtrl', function($scope){
  $scope.$on('BOOM!', function(events, args){
    console.log(args);
    $scope.name = args; //now we've registered!
  })
});

It's really that simple. Live Example

Other ways to achieve similar results

Try to avoid using this suite of methods as it is neither efficient nor easy to maintain but it's a simple way to fix issues you might have.

You can usually do the same thing by using a service or by simplifying your controllers. We won't discuss this in detail but I thought I'd just mention it for completeness.

Lastly, keep in mind a really useful broadcast to listen to is '$destroy' again you can see the $ means it's a method or object created by the vendor codes. Anyways $destroy is broadcasted when a controller gets destroyed, you may want to listen to this to know when your controller is removed.

It actually depends on the plugins you plan to use as some plugins change the root document of the wordpress. but generally I recommend something like this for the wordpress directory.

This will assign the "root" (or whatever the user you are using) as the user in every single file/folder, R means recursive, so it just doesn't stop at the "html" folder. if you didn't use R, then it only applicable to the "html" directory.

sudo chown -R root:www-data /var/www/html  

This will set the owner/group of "wp-content" to "www-data" and thus allowing the web server to install the plugins through the admin panel.

chown -R www-data:www-data /var/www/html/wp-content

This will set the permission of every single file in "html" folder (Including files in subdirectories) to 644, so outside people can't execute any file, modify any file, group can't execute any file, modify any file and only the user is allowed to modify/read files, but still even the user can't execute any file. This is important because it prevents any kind of execution in "html" folder, also since the owner of the html folder and all other folders except the wp-content folder are "root" (or your user), the www-data can't modify any file outside of the wp-content folder, so even if there is any vulnerability in the web server, and if someone accessed to the site unauthorizedly, they can't delete the main site except the plugins.

sudo find /var/www/html -type f -exec chmod 644 {} +

This will restrict the permission of accessing to "wp-config.php" to user/group with rw-r----- these permissions.

chmod 640 /var/www/html/wp-config.php

And if a plugin or update complained it can't update, then access to the SSH and use this command, and grant the temporary permission to "www-data" (web server) to update/install through the admin panel, and then revert back to the "root" or your user once it's completed.

chown -R www-data /var/www/html

And in Nginx (same procedure for the apache)to protect the wp-admin folder from unauthorized accessing, and probing. apache2-utils is required for encrypting the password even if you have nginx installed, omit c if you plan to add more users to the same file.

sudo apt-get install apache2-utils
sudo htpasswd -c /etc/nginx/.htpasswd userName

Now visit this location

/etc/nginx/sites-available/

Use this codes to protect "wp-admin" folder with a password, now it will ask the password/username if you tried to access to the "wp-admin". notice, here you use the ".htpasswd" file which contains the encrypted password.

location ^~ /wp-admin {
    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/.htpasswd;
    index  index.php index.html index.htm;
}

Now restart the nginx.

sudo /etc/init.d/nginx restart

Note: If its a React Native project

If you open the root project folder in Android Studio, you wont see the options suggested in other answers in this page.

Solution

Instead of the root folder I opened the packages/native/android folder. Then only I could see the options to build signed APK.

Nested fragments are not currently supported. Trying to put a fragment within the UI of another fragment will result in undefined and likely broken behavior.

Update: Nested fragments are supported as of Android 4.2 (and Android Support Library rev 11) : http://developer.android.com/about/versions/android-4.2.html#NestedFragments

NOTE (as per this docs): "Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically."

Step1: copy all the rpm pkg in given locations

Step2: if createrepo is not already installed, as it will not be by default, install it.

[root@pavangildamysql1 8.0.11_rhel7]# yum install createrepo

Step3: create repository metedata and give below permission

[root@pavangildamysql1 8.0.11_rhel7]# chown -R root.root /scratch/PVN/8.0.11_rhel7
[root@pavangildamysql1 8.0.11_rhel7]# createrepo /scratch/PVN/8.0.11_rhel7

If you are using fedora then first install tkinter

sudo dnf install python3-tkinter

I don't think you need to import tkinter afterwards I also suggest you to use virtualenv

$ python3 -m venv myvenv
$ source myvenv/bin/activate

And add the necessary packages using pip

You need xlutils.copy. Try something like this:

from xlutils.copy import copy
w = copy('book1.xls')
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')

Keep in mind you can't overwrite cells by default as noted in this question.

Add the following to the header:

<script language="javascript" type="text/javascript">
function limitText(limitField, limitNum) {
    if (limitField.value.length > limitNum) {
        limitField.value = limitField.value.substring(0, limitNum);
    }
}
</script>

    <input type="text" id="sessionNo" name="sessionNum" onKeyDown="limitText(this,5);" 
onKeyUp="limitText(this,5);"" />

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"
done

list='"item 1" "item 2" "item 3"'
for i in $list; do
    echo $i
done
for i in "$list"; do
    echo $i
done
for i in ${array[@]}; do
    echo $i
done

you have to check your pip package to be updated to the latest version in your pycharm and then install numpy package. in settings -> project:progLangComp -> Project Interpreter there is a table of packages and their current version (just labelled as Version) and their latest version (labelled as Latest). Pip current version number should be the same as latest version. If you see a blue arrow in front of pip, you have to update it to the latest then trying to install numpy or any other packages that you couldn't install, for me it was pandas which I wanted to install.

In file wp-config.php you can find constant WP_DEBUG. Make sure it is set to false.

define('WP_DEBUG', false);

This is for WordPress 3.x.

Correction:

On the emulator and most devices System.out.println gets redirected to LogCat and printed using Log.i(). This may not be true on very old or custom Android versions.

Original:

There is no console to send the messages to so the System.out.println messages get lost. In the same way this happens when you run a "traditional" Java application with javaw.

Instead, you can use the Android Log class:

Log.d("MyApp","I am here");

You can then view the log either in the Logcat view in Eclipse, or by running the following command:

adb logcat

It's good to get in to the habit of looking at logcat output as that is also where the Stack Traces of any uncaught Exceptions are displayed.

The first Entry to every logging call is the log tag which identifies the source of the log message. This is helpful as you can filter the output of the log to show just your messages. To make sure that you're consistent with your log tag it's probably best to define it once as a static final String somewhere.

Log.d(MyActivity.LOG_TAG,"Application started");

There are five one-letter methods in Log corresponding to the following levels:

• e() - Error
• w() - Warning
• i() - Information
• d() - Debug
• v() - Verbose
• wtf() - What a Terrible Failure

The documentation says the following about the levels:

Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

Using the := walrus operator available in Python 3.8+:

>>> t = [1, 3, 6]
>>> prev = t[0]; [-prev + (prev := x) for x in t[1:]]
[2, 3]

If you load URL from bitmap without using AsyncTask, write two lines after setContentView(R.layout.abc);

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

try {
    URL url = new URL("http://....");
    Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch(IOException e) {
    System.out.println(e);
}

You may come across code that reads from an InputStream and uses the snippet while(in.available()>0) to check for the end of the stream, rather than checking for an EOFException (end of the file).

The problem with this technique, and the Javadoc does echo this, is that it only tells you the number of blocks that can be read without blocking the next caller. In other words, it can return 0 even if there are more bytes to be read. Therefore, the InputStream available() method should never be used to check for the end of the stream.

You must use while (true) and

catch(EOFException e) {
//This isn't problem
} catch (Other e) {
//This is problem
}

A simpler solution that works for me:

=COUNTIFS(A:A;"<>"&"")

It counts both numbers, strings, dates, etc that are not empty

These three commands have entirely different purposes. They are not even remotely similar.

git revert

This command creates a new commit that undoes the changes from a previous commit. This command adds new history to the project (it doesn't modify existing history).

git checkout

This command checks-out content from the repository and puts it in your work tree. It can also have other effects, depending on how the command was invoked. For instance, it can also change which branch you are currently working on. This command doesn't make any changes to the history.

git reset

This command is a little more complicated. It actually does a couple of different things depending on how it is invoked. It modifies the index (the so-called "staging area"). Or it changes which commit a branch head is currently pointing at. This command may alter existing history (by changing the commit that a branch references).

Using these commands

If a commit has been made somewhere in the project's history, and you later decide that the commit is wrong and should not have been done, then git revert is the tool for the job. It will undo the changes introduced by the bad commit, recording the "undo" in the history.

If you have modified a file in your working tree, but haven't committed the change, then you can use git checkout to checkout a fresh-from-repository copy of the file.

If you have made a commit, but haven't shared it with anyone else and you decide you don't want it, then you can use git reset to rewrite the history so that it looks as though you never made that commit.

These are just some of the possible usage scenarios. There are other commands that can be useful in some situations, and the above three commands have other uses as well.

The singular form dtype is used to check the data type for a single column. And the plural form dtypes is for data frame which returns data types for all columns. Essentially:

For a single column:

dataframe.column.dtype

For all columns:

dataframe.dtypes

Example:

import pandas as pd
df = pd.DataFrame({'A': [1,2,3], 'B': [True, False, False], 'C': ['a', 'b', 'c']})

df.A.dtype
# dtype('int64')
df.B.dtype
# dtype('bool')
df.C.dtype
# dtype('O')

df.dtypes
#A     int64
#B      bool
#C    object
#dtype: object

Try this namespaces module

namespaceModuleFile.ts

export namespace Bookname{
export class Snows{
    name:any;
    constructor(bookname){
        console.log(bookname);
    }
}
export class Adventure{
    name:any;
    constructor(bookname){
        console.log(bookname);
    }
}
}





export namespace TreeList{
export class MangoTree{
    name:any;
    constructor(treeName){
        console.log(treeName);
    }
}
export class GuvavaTree{
    name:any;
    constructor(treeName){
        console.log(treeName);
    }
}
}

bookTreeCombine.ts

---compilation part---

import {Bookname , TreeList} from './namespaceModule';
import b = require('./namespaceModule');
let BooknameLists = new Bookname.Adventure('Pirate treasure');

const TreeLis = new TreeList.MangoTree('trees present in nature');
const TreeLists = new TreeList.GuvavaTree('trees are the celebraties');

You should use the new lightweight View Space to draw dividers. Your layout will load faster if you will use Space instead of View.

Horizontal divider:

<android.support.v4.widget.Space
        android:layout_height="1dp"
        android:layout_width="match_parent" /> 

Vertical divider:

<android.support.v4.widget.Space
        android:layout_height="match_parent"
        android:layout_width="1dp" />

You can also add a background:

<android.support.v4.widget.Space
        android:layout_height="match_parent"
        android:layout_width="1dp"
        android:background="?android:attr/listDivider"/>

Usage example:

....
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="One"/>

<android.support.v4.widget.Space
    android:layout_height="match_parent"
    android:layout_width="1dp"
    android:background="?android:attr/listDivider"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Two"/>

<android.support.v4.widget.Space
    android:layout_height="match_parent"
    android:layout_width="1dp"
    android:background="?android:attr/listDivider"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Three"/>
....

In order to use Space you should add the dependency in your build.gradle:

dependencies {
    compile 'com.android.support:support-v4:22.1.+'
}

Documentation https://developer.android.com/reference/android/support/v4/widget/Space.html

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

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

    // do stuff with y
}

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

I want to make a more comprehensive answer based off of the most of the potential solutions that are already provided. I also want to point out one more potential aid that may help reading process.

Option 1: dtypes

"dtypes" is a pretty powerful parameter that you can use to reduce the memory pressure of read methods. See this and this answer. Pandas, on default, try to infer dtypes of the data.

Referring to data structures, every data stored, a memory allocation takes place. At a basic level refer to the values below (The table below illustrates values for C programming language):

The maximum value of UNSIGNED CHAR = 255                                    
The minimum value of SHORT INT = -32768                                     
The maximum value of SHORT INT = 32767                                      
The minimum value of INT = -2147483648                                      
The maximum value of INT = 2147483647                                       
The minimum value of CHAR = -128                                            
The maximum value of CHAR = 127                                             
The minimum value of LONG = -9223372036854775808                            
The maximum value of LONG = 9223372036854775807

Refer to this page to see the matching between NumPy and C types.

Let's say you have an array of integers of digits. You can both theoretically and practically assign, say array of 16-bit integer type, but you would then allocate more memory than you actually need to store that array. To prevent this, you can set dtype option on read_csv. You do not want to store the array items as long integer where actually you can fit them with 8-bit integer (np.int8 or np.uint8).

Observe the following dtype map.

Source: https://pbpython.com/pandas_dtypes.html

You can pass dtype parameter as a parameter on pandas methods as dict on read like {column: type}.

import numpy as np
import pandas as pd

df_dtype = {
        "column_1": int,
        "column_2": str,
        "column_3": np.int16,
        "column_4": np.uint8,
        ...
        "column_n": np.float32
}

df = pd.read_csv('path/to/file', dtype=df_dtype)

Option 2: Read by Chunks

Reading the data in chunks allows you to access a part of the data in-memory, and you can apply preprocessing on your data and preserve the processed data rather than raw data. It'd be much better if you combine this option with the first one, dtypes.

I want to point out the pandas cookbook sections for that process, where you can find it here. Note those two sections there;

• Reading a csv chunk-by-chunk
• Reading only certain rows of a csv chunk-by-chunk

Option 3: Dask

Dask is a framework that is defined in Dask's website as:

Dask provides advanced parallelism for analytics, enabling performance at scale for the tools you love

It was born to cover the necessary parts where pandas cannot reach. Dask is a powerful framework that allows you much more data access by processing it in a distributed way.

You can use dask to preprocess your data as a whole, Dask takes care of the chunking part, so unlike pandas you can just define your processing steps and let Dask do the work. Dask does not apply the computations before it is explicitly pushed by compute and/or persist (see the answer here for the difference).

Other Aids (Ideas)

• ETL flow designed for the data. Keeping only what is needed from the raw data.
  • First, apply ETL to whole data with frameworks like Dask or PySpark, and export the processed data.
  • Then see if the processed data can be fit in the memory as a whole.
• Consider increasing your RAM.
• Consider working with that data on a cloud platform.

Unfortunately: NO.

We're all eagerly awaiting the Java support for extension methods

I had a similar problem when I had installed the 12c database as per Oracle's tutorial . The instruction instructs reader to create a PLUGGABLE DATABASE (pdb).

The problem

sqlplus hr/hr@pdborcl would result in ORACLE initialization or shutdown in progress.

The solution

• 1. Login as SYSDBA to the dabase :

     sqlplus SYS/Oracle_1@pdborcl AS SYSDBA
     

• 2. Alter database:

     alter pluggable database pdborcl open read write;
     

• 3. Login again:

     sqlplus hr/hr@pdborcl
     

That worked for me

Some documentation here

In Swift 4, if you are traversing through your DataModel array, make sure your data model conforms to Equatable Protocol , implement the lhs=rhs method , and only then you can use ".index(of" . For example

class Photo : Equatable{
    var imageURL: URL?
    init(imageURL: URL){
        self.imageURL = imageURL
    }

    static func == (lhs: Photo, rhs: Photo) -> Bool{
        return lhs.imageURL == rhs.imageURL
    }
}

And then,

let index = self.photos.index(of: aPhoto)

Step 1: create a MANIFEST.in file in the same folder with setup.py

Step 2: include the relative path to the files you want to add in MANIFEST.in

include README.rst
include docs/*.txt
include funniest/data.json

Step 3: set include_package_data=True in the setup() function to copy these files to site-package

Reference is here.

You can use Google Translate API v2 Java. It has a core module that you can call from your Java code and also a command line interface module.

Using the form you already have:

var input = document.querySelector('form[name=myForm] #username');

input.onkeyup = function() {
    var patterns = /[^0-9]/g;
    var caretPos = this.selectionStart;

    this.value = input.value.replace(patterns, '');
    this.setSelectionRange(caretPos, caretPos);
}

This will delete all non-digits after the key is released.

It imports once when the function executes first time.

Pros:

• imports related to the function they're used in
• easy to move functions around the package

Cons:

• couldn't see what modules this module might depend on

If you actually create the buffer as per dirks suggestion, then:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE);

may completely fill the buffer, possibly overwriting the terminating zero character which you depend on when extracting to a stringstream. You need:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE - 1 );

I am posting an answer to provide an updated solution and explanation as to why this problem can occur. Say you are getting this data from a database or Excel workbook. If you have special characters like La Cañada Flintridge city, well unless you are exporting the data using UTF-8 encoding, you're going to introduce errors. La Cañada Flintridge city will become La Ca\xf1ada Flintridge city. If you are using pandas.read_csv without any adjustments to the default parameters, you'll hit the following error

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 5: invalid continuation byte

Fortunately, there are a few solutions.

Option 1, fix the exporting. Be sure to use UTF-8 encoding.

Option 2, if fixing the exporting problem is not available to you, and you need to use pandas.read_csv, be sure to include the following paramters, engine='python'. By default, pandas uses engine='C' which is great for reading large clean files, but will crash if anything unexpected comes up. In my experience, setting encoding='utf-8' has never fixed this UnicodeDecodeError. Also, you do not need to use errors_bad_lines, however, that is still an option if you REALLY need it.

pd.read_csv(<your file>, engine='python')

Option 3: solution is my preferred solution personally. Read the file using vanilla Python.

import pandas as pd

data = []

with open(<your file>, "rb") as myfile:
    # read the header seperately
    # decode it as 'utf-8', remove any special characters, and split it on the comma (or deliminator)
    header = myfile.readline().decode('utf-8').replace('\r\n', '').split(',')
    # read the rest of the data
    for line in myfile:
        row = line.decode('utf-8', errors='ignore').replace('\r\n', '').split(',')
        data.append(row)

# save the data as a dataframe
df = pd.DataFrame(data=data, columns = header)

Hope this helps people encountering this issue for the first time.

git diff --stat commit1 commit2

EDIT: You have to specify the commits as well (without parameters it compares the working directory against the index). E.g.

git diff --stat HEAD^ HEAD

to compare the parent of HEAD with HEAD.

all these answers has the problem, that's always stretching the image to pagesize and cuts off some content at trying this.
Found a little bit easier way.

My own solution only stretch(is this the right word?) if the image is to large, can use multiply copies and pageorientations.

                PrintDialog dlg = new PrintDialog();

            if (dlg.ShowDialog() == true)
            {
                BitmapImage bmi = new BitmapImage(new Uri(strPath));

                Image img = new Image();
                img.Source = bmi;

                if (bmi.PixelWidth < dlg.PrintableAreaWidth ||
                           bmi.PixelHeight < dlg.PrintableAreaHeight)
                {
                    img.Stretch = Stretch.None;
                    img.Width = bmi.PixelWidth;
                    img.Height = bmi.PixelHeight;
                }


                if (dlg.PrintTicket.PageBorderless == PageBorderless.Borderless)
                {
                    img.Margin = new Thickness(0);
                }
                else
                {
                    img.Margin = new Thickness(48);
                }
                img.VerticalAlignment = VerticalAlignment.Top;
                img.HorizontalAlignment = HorizontalAlignment.Left;

                for (int i = 0; i < dlg.PrintTicket.CopyCount; i++)
                {
                    dlg.PrintVisual(img, "Print a Image");
                }
            }

Below is a working code to add a fragment e.g 3 times to a vertical LinearLayout (xNumberLinear). You can change number 3 with any other number or take a number from a spinner!

for (int i = 0; i < 3; i++) {
            LinearLayout linearDummy = new LinearLayout(getActivity());
            linearDummy.setOrientation(LinearLayout.VERTICAL);
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {

                Toast.makeText(getActivity(), "This function works on newer versions of android", Toast.LENGTH_LONG).show();

            } else {
                linearDummy.setId(View.generateViewId());
            }
            fragmentManager.beginTransaction().add(linearDummy.getId(), new SomeFragment(),"someTag1").commit();

            xNumberLinear.addView(linearDummy);
        }

A easy way is

1. type in from google.colab import files uploaded = files.upload()
2. copy the code
3. paste in colab cell

Since whitespace has semantic meaning in Python, some methods of word wrapping could produce incorrect or ambiguous results, so there needs to be some limit to avoid those situations. An 80 character line length has been standard since we were using teletypes, so 79 characters seems like a pretty safe choice.

 $singleArray = array();

    foreach ($multiDimensionalArray as $key => $value){
        $singleArray[$key] = $value['plan'];
    }

this is best way to create a array from multiDimensionalArray array.

thanks

Tuples are known values which is used to relate the table in relational DB.

I'm late to the party, but I had this same issue working with Java 8.

This is what worked for me, on the HttpServletRequest request object.

request.getHeader("origin");

and

request.getHeader("referer");

How I came to that conclusion:

I have a java app running on http://localhost:3000 making a Http Post to another java app I have running on http://localhost:8080.

From the Java code running on http://localhost:8080 I couldn't get the http://localhost:3000 from the HttpServletRequest using the answers above. For me using the getHeader method with the correct string input worked.

request.getHeader("origin") gave me "http://localhost:3000" which is what I wanted.

request.getHeader("referer") gave me "http://localhost:3000/xxxx" where xxxx is full URL I have from the requesting app.

You can also set this directly from Interface Builder under the Attributes Inspector.

Answer from 2020 year :

dependencies {
    implementation "androidx.core:core-ktx:1.2.0"
}

and cal it simply in your code

view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
   setMargins(5)
}

I think it is better practice to keep your response under single control and for this reason I found out the most official solution.

response()->json([...])
    ->setStatusCode(Response::HTTP_OK, Response::$statusTexts[Response::HTTP_OK]);

add this after namespace declaration:

use Illuminate\Http\Response;

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

There are many ways to tackle a problem like this. There are many ways to do this. I'm going to give you the most simple solution to this question I know. When changing the text of a label or any kind of wiget really. I would do it like this.

Name_Of_Label["text"] = "Your New Text"

So when I apply this knowledge to your code. It would look something like this.

from tkinter import*

class MyGUI:
   def __init__(self):
    self.__mainWindow = Tk()
    #self.fram1 = Frame(self.__mainWindow)
    self.labelText = 'Enter amount to deposit'
    self.depositLabel = Label(self.__mainWindow, text = self.labelText)
    self.depositEntry = Entry(self.__mainWindow, width = 10)
    self.depositEntry.bind('<Return>', self.depositCallBack)
    self.depositLabel.pack()
    self.depositEntry.pack()

    mainloop()

  def depositCallBack(self,event):
    self.labelText["text"] = 'change the value'
    print(self.labelText)

myGUI = MyGUI()

If this helps please let me know!

<?php
set_time_limit(0);
//This is the file where we save the    information
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
// write curl response to file
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// get curl response
curl_exec($ch); 
curl_close($ch);

You need to split the line first.

import csv

with open('log.txt', 'r') as in_file:
    stripped = (line.strip() for line in in_file)
    lines = (line.split(",") for line in stripped if line)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro'))
        writer.writerows(lines)

Be aware that if you are trying to reach a shared folder path from your code, you dont only need to give the proper permissions to the physicial folder thru the security tab. You also need to "share" the folder with the corresponding app pool user thru the Share Tab

C style, simple ring buffer for integers. First use init than use put and get. If buffer does not contain any data it returns "0" zero.

PURE JS (works also when arrays and subarrays has more than 2 elements with arbitrary order). If strings contains , use as join('-') parametr character (can be utf) which is not used in strings

You are touching multiple issues here:

1) A stack trace should never be visibile to end users (for user experience and security purposes)

Yes, it should be accessible to diagnose problems of end-users, but end-user should not see them for two reasons:

• They are very obscure and unreadable, the application will look very user-unfriendly.
• Showing a stack trace to end-user might introduce a potential security risk. Correct me if I'm wrong, PHP actually prints function parameters in stack trace - brilliant, but very dangerous - if you would you get exception while connecting to the database, what are you likely to in the stacktrace?

2) Generating a stack trace is a relatively expensive process (though unlikely to be an issue in most 'exception'al circumstances)

Generating a stack trace happens when the exception is being created/thrown (that's why throwing an exception comes with a price), printing is not that expensive. In fact you can override Throwable#fillInStackTrace() in your custom exception effectively making throwing an exception almost as cheap as a simple GOTO statement.

3) Many logging frameworks will print the stack trace for you (ours does not and no, we can't change it easily)

Very good point. The main issue here is: if the framework logs the exception for you, do nothing (but make sure it does!) If you want to log the exception yourself, use logging framework like Logback or Log4J, to not put them on the raw console because it is very hard to control it.

With logging framework you can easily redirect stack traces to file, console or even send them to a specified e-mail address. With hardcoded printStackTrace() you have to live with the sysout.

4) Printing the stack trace does not constitute error handling. It should be combined with other information logging and exception handling.

Again: log SQLException correctly (with the full stack trace, using logging framework) and show nice: "Sorry, we are currently not able to process your request" message. Do you really think the user is interested in the reasons? Have you seen StackOverflow error screen? It's very humorous, but does not reveal any details. However it ensures the user that the problem will be investigated.

But he will call you immediately and you need to be able to diagnose the problem. So you need both: proper exception logging and user-friendly messages.

To wrap things up: always log exceptions (preferably using logging framework), but do not expose them to the end-user. Think carefully and about error-messages in your GUI, show stack traces only in development mode.

Actually the enhanced for loop should look like this

for (final Room room : rooms) {
          // Here your room is available
}

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

Right-click on an Eclipse project then "Export" then "General" then "Ant build files". I don't think it is possible to customise the output format though.

Couple of points:

• I believe git stash + git stash drop could be replaced with git reset --hard

• ... or, even shorter, add -f to checkout command:

  git checkout -f -b $branch
  

  That will discard any local changes, just as if git reset --hard was used prior to checkout.

As for the main question: instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.

Since Bootstrap 3 removed the submenu part and we need to adapt ourselves the style, I think it's better to go with SmartMenu Bootstrap: https://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar.html#

That would save us time on mobile responsive and style.

This plugin also very promising.

The way I typically handle this is with a second piece of software. For Windows I use Notepad++, for OS X I use Sublime Text 2.

1. In Excel, hit Control + ~ (OS X)
2. Excel will convert all values to their formula version
3. CMD + A (I usually do this twice) to select the entire sheet
4. Copy all contents and paste them into Notepad++/Sublime Text 2
5. Find / Replace your formula contents here
6. Copy the contents and paste back into Excel, confirming any issues about cell size differences
7. Control + ~ to switch back to values mode

That's the correct way. Calendars work the same way. The best I could offer you (based on your example) is this:

boolean isWithinRange(Date testDate) {
    return testDate.getTime() >= startDate.getTime() &&
             testDate.getTime() <= endDate.getTime();
}

Date.getTime() returns the number of milliseconds since 1/1/1970 00:00:00 GMT, and is a long so it's easily comparable.

Provide your package name separately, it requires a String[] for package names.

Instead of this:

@ComponentScan("com.my.package.first,com.my.package.second")

Use this:

@ComponentScan({"com.my.package.first","com.my.package.second"})

Use the enumerate() function to generate the index along with the elements of the sequence you are looping over:

for index, w in enumerate(loopme):
    print "CURRENT WORD IS", w, "AT CHARACTER", index 

This maybe too late but No one provided a clear explanation of how the algorithm works

The idea of Dijkstra is simple, let me show this with the following pseudocode.

Dijkstra partitions all nodes into two distinct sets. Unsettled and settled. Initially all nodes are in the unsettled set, e.g. they must be still evaluated.

At first only the source node is put in the set of settledNodes. A specific node will be moved to the settled set if the shortest path from the source to a particular node has been found.

The algorithm runs until the unsettledNodes set is empty. In each iteration it selects the node with the lowest distance to the source node out of the unsettledNodes set. E.g. It reads all edges which are outgoing from the source and evaluates each destination node from these edges which are not yet settled.

If the known distance from the source to this node can be reduced when the selected edge is used, the distance is updated and the node is added to the nodes which need evaluation.

Please note that Dijkstra also determines the pre-successor of each node on its way to the source. I left that out of the pseudo code to simplify it.

A little bit late, but here's an extension that enable you to find a responder of any type, including ViewController.

extension NSObject{
func findNext(type: AnyClass) -> Any{
    var resp = self as! UIResponder

    while !resp.isKind(of: type.self) && resp.next != nil
    {
        resp = resp.next!
    }

    return resp
  }                       
}

First Create Procedure as Below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split`(str nvarchar(6500), dilimiter varchar(15), tmp_name varchar(50))
BEGIN

    declare end_index   int;
    declare part        nvarchar(6500);
    declare remain_len  int;

    set end_index      = INSTR(str, dilimiter);

    while(end_index   != 0) do

        /* Split a part */
        set part       = SUBSTRING(str, 1, end_index - 1);

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, part);

        set remain_len = length(str) - end_index;
        set str = substring(str, end_index + 1, remain_len);

        set end_index  = INSTR(str, dilimiter);

    end while;

    if(length(str) > 0) then

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, str);

    end if;

END

After that create procedure as below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split_insert`(tb_name varchar(255), tb_value nvarchar(6500))
BEGIN
    SET @sql = CONCAT('Insert Into ', tb_name,'(item) Values(?)'); 
    PREPARE s1 from @sql;
    SET @paramA = tb_value;
    EXECUTE s1 USING @paramA;
END

How call test

CREATE DEFINER=`root`@`%` PROCEDURE `test_split`(test_text nvarchar(255))
BEGIN

    create temporary table if not exists tb_search
        (
            item nvarchar(6500)
        );

    call sp_split(test_split, ',', 'tb_search');

    select * from tb_search where length(trim(item)) > 0;

    drop table tb_search;

I often use this workaround in CLI where instead of configuring my .gitignore, I create a separate .include file where I define the (sub)directories I want included in spite of directories directly or recursively ignored by .gitignore.

Thus, I additionally use

git add `cat .include`

during staging, before committing.

To the OP, I suggest using a .include which has these lines:

<parent_folder_path>/application/language/gr/*

NOTE: Using cat does not allow usage of aliases (within .include) for specifying $HOME (or any other specific directory). This is because the line homedir/app1/* when passed to git add using the above command appears as git add 'homedir/app1/*', and enclosing characters in single quotes ('') preserves the literal value of each character within the quotes, thus preventing aliases (such as homedir) from functioning (see Bash Single Quotes).

Here is an example of a .include file I use in my repo here.

/home/abhirup/token.txt
/home/abhirup/.include
/home/abhirup/.vim/*
/home/abhirup/.viminfo
/home/abhirup/.bashrc
/home/abhirup/.vimrc
/home/abhirup/.condarc

use js:

 $(document).ready(function ()
   { $(".class-span").each(function(i){
        var len=$(this).text().trim().length;
        if(len>100)
        {
            $(this).text($(this).text().substr(0,100)+'...');
        }
    });
 });

I know I am wayyy too late to write an answer for this question but nevertheless I think this will be use for anybody who is thinking of sending emails out via javascript.

The first way I would suggest is using a callback to do this on the server. If you really want it to be handled using javascript folowing is what I recommend.

The easiest way I found was using smtpJs. A free library which can be used to send emails.

1.Include the script like below

<script src="https://smtpjs.com/v3/smtp.js"></script>

2. You can either send an email like this

Email.send({_x000D_
    Host : "smtp.yourisp.com",_x000D_
    Username : "username",_x000D_
    Password : "password",_x000D_
    To : '[email protected]',_x000D_
    From : "[email protected]",_x000D_
    Subject : "This is the subject",_x000D_
    Body : "And this is the body"_x000D_
    }).then(_x000D_
      message => alert(message)_x000D_
    );

Which is not advisable as it will display your password on the client side.Thus you can do the following which encrypt your SMTP credentials, and lock it to a single domain, and pass a secure token instead of the credentials instead.

Email.send({_x000D_
    SecureToken : "C973D7AD-F097-4B95-91F4-40ABC5567812",_x000D_
    To : '[email protected]',_x000D_
    From : "[email protected]",_x000D_
    Subject : "This is the subject",_x000D_
    Body : "And this is the body"_x000D_
}).then(_x000D_
  message => alert(message)_x000D_
);

Finally if you do not have a SMTP server you use an smtp relay service such as Elastic Email

Also here is the link to the official SmtpJS.com website where you can find all the example you need and the place where you can create your secure token.

I hope someone find this details useful. Happy coding.

According to the latest document when state is set to be directory, you don't need to use parameter recurse to create parent directories, file module will take care of it.

- name: create directory with parent directories
  file:
    path: /data/test/foo
    state: directory

this is fare enough to create the parent directories data and test with foo

please refer the parameter description - "state" http://docs.ansible.com/ansible/latest/modules/file_module.html

SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.

When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.

There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.

The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.

Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).

If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.

Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.

Traditional (well not all the way back to the beginning) arm syntax:

...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...

stm is store multiple you can save more than one register at a time, up to all of them in one instruction.

db means decrement before, this is a downward moving stack from high addresses to lower addresses.

You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.

The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.

Then in the brackets { } list the registers you want to save, comma separated.

ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm

So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.

Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:

void myfun ( void )
{
   int somedata;
}

In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.

A global variable would not be found on the stack.

Going back...

Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.

...
bl myfun
    <--- the return from my fun returns here
...


myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
   <---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.

So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.

ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use

push {r5,r6}
...
pop {r5,r6}

in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).

No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.

push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}

assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.

The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.

If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.

sorry for the very long post, hope it is useful.

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

There is a case for either solution, depending on what you want to do conditional on the existence of the environment variable.

Case 1

When you want to take different actions purely based on the existence of the environment variable, without caring for its value, the first solution is the best practice. It succinctly describes what you test for: is 'FOO' in the list of environment variables.

if 'KITTEN_ALLERGY' in os.environ:
    buy_puppy()
else:
    buy_kitten()

Case 2

When you want to set a default value if the value is not defined in the environment variables the second solution is actually useful, though not in the form you wrote it:

server = os.getenv('MY_CAT_STREAMS', 'youtube.com')

or perhaps

server = os.environ.get('MY_CAT_STREAMS', 'youtube.com')

Note that if you have several options for your application you might want to look into ChainMap, which allows to merge multiple dicts based on keys. There is an example of this in the ChainMap documentation:

[...]
combined = ChainMap(command_line_args, os.environ, defaults)

I had a similar issue. It is caused due the dependent package 'rJava'. This problem can be overcome by re-directing the R to use a different JAVA_HOME.

if(Sys.getenv("JAVA_HOME")!=""){
    Sys.setenv(JAVA_HOME="")
}
library(rJava)

This worked for me.

Hide the input with css, add a label and assign it to input button. label will be clickable and when clicked, it will fire up the file dialog.

<input type="file" id="files" class="hidden"/>
<label for="files">Select file</label>

Then style the label as a button if you want.

For whatever reason, @import didn't work for me, but it's not really necessary is it?

Here's what I did instead, within the html:

  <link rel="stylesheet" media="print" href="myap-print.css">
  <link rel="stylesheet" media="print" href="myap-screen.css">
  <link rel="stylesheet" media="screen" href="myap-screen.css">

Notice that media="print" has 2 stylesheets: myap-print.css and myap-screen.css. It's the same effect as including myap-screen.css within myap-print.css.

Different Environments

Typically, software will run in different environments:

• development
• testing
• staging
• production

Different Dependencies in Different Environments

The dependencies which are declared in the require section of composer.json are typically dependencies which are required for running an application or a package in

• staging
• production

environments, whereas the dependencies declared in the require-dev section are typically dependencies which are required in

• developing
• testing

environments.

For example, in addition to the packages used for actually running an application, packages might be needed for developing the software, such as:

• friendsofphp/php-cs-fixer (to detect and fix coding style issues)
• squizlabs/php_codesniffer (to detect and fix coding style issues)
• phpunit/phpunit (to drive the development using tests)
• etc.

Deployment

Now, in development and testing environments, you would typically run

$ composer install

to install both production and development dependencies.

However, in staging and production environments, you only want to install dependencies which are required for running the application, and as part of the deployment process, you would typically run

$ composer install --no-dev

to install only production dependencies.

Semantics

In other words, the sections

• require
• require-dev

indicate to composer which packages should be installed when you run

$ composer install

or

$ composer install --no-dev

That is all.

Note Development dependencies of packages your application or package depend on will never be installed

For reference, see:

• https://getcomposer.org/doc/04-schema.md#require
• https://getcomposer.org/doc/04-schema.md#require-dev

Most of the above work, but for me, this was the easiest.

Install the plugin, log out, log in, system, advanced, front end links manager, check and uncheck the options you want to show. It also works on any of the front end navigation's on your site.

http://www.magentocommerce.com/magento-connect/frontend-links-manager.html

For some cases UIWebView is a good solution. Because:

• it displays tables, images, other files
• it's fast (comparing with NSAttributedString: NSHTMLTextDocumentType)
• it's out of the box

Using NSAttributedString can lead to crashes, if html is complex or contains tables (so example)

For loading text to web view you can use the following snippet (just example):

func loadHTMLText(_ text: String?, font: UIFont) {
        let fontSize = font.pointSize * UIScreen.screens[0].scale
        let html = """
        <html><body><span style=\"font-family: \(font.fontName); font-size: \(fontSize)\; color: #112233">\(text ?? "")</span></body></html>
        """
        self.loadHTMLString(html, baseURL: nil)
    }

Perhaps your Apache is bounded to localhost only. Look in your apache configuration file for:

Listen 127.0.0.1:80

If you found it, replace it for:

Listen 80

I was looking for same thing but in number, means from integer xx hour, xx minutes and AM/PM to 24 hour format xx hour and xx minutes, so here what i have done:

private static final int PM = 1;
/**

   * afternoon 12 is 12PM, 12:xxAM is basically 00:xxAM
   * @param hour12Format
   * @param amPm
   * @return
   */
  private int get24FormatHour(int hour12Format,int amPm){
    if(hour12Format==12 && amPm==AM){
      hour12Format=0;
    }
    if(amPm == PM && hour12Format!=12){
      hour12Format+=12;
    }
    return hour12Format;
  }`

    private int minutesTillMidnight(int hour12Format,int minutes, int amPm){
        int hour24Format=get24FormatHour(hour12Format,amPm);
        System.out.println("24 Format :"+hour24Format+":"+minutes); 
        return (hour24Format*60)+minutes;
      }

Rxjs v 6.*

It got simplified with newer version of rxjs .

1) Operators

import {map} from 'rxjs/operators';

2) Others

import {Observable,of, from } from 'rxjs';

Instead of chaining we need to pipe . For example

Old syntax :

source.map().switchMap().subscribe()

New Syntax:

source.pipe(map(), switchMap()).subscribe()

Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:

do -> tap,

catch -> catchError

switch -> switchAll

finally -> finalize

Rxjs v 5.*

I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.

1) import { Rx } from 'rxjs/Rx';

This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.

public cache = new Rx.BehaviorSubject('');

Or you can import individual operators .

This will Optimize your app to use only those files :

2) import { _______ } from 'rxjs/_________';

This syntax usually used for main Object like Rx itself or Observable etc.,

Keywords which can be imported with this syntax

 Observable, Observer, BehaviorSubject, Subject, ReplaySubject

3) import 'rxjs/add/observable/__________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';

These are usually accompanied with Observable directly. For example

Observable.from()
Observable.of()

Other such keywords which can be imported using this syntax:

concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of, 
range, throw, timer, using, zip

4) import 'rxjs/add/operator/_________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';

These usually come in the stream after the Observable is created. Like flatMap in this code snippet:

Observable.of([1,2,3,4])
          .flatMap(arr => Observable.from(arr));

Other such keywords using this syntax:

audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay, 
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck, 
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take, 
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip

FlatMap: flatMap is alias to mergeMap so we need to import mergeMap to use flatMap.

Note for /add imports :

We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.

Add

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

Method

String getUUID(){
    TelephonyManager teleManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
    String tmSerial = teleManager.getSimSerialNumber();
    String tmDeviceId = teleManager.getDeviceId();
    String androidId = android.provider.Settings.Secure.getString(getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
    if (tmSerial  == null) tmSerial   = "1";
    if (tmDeviceId== null) tmDeviceId = "1";
    if (androidId == null) androidId  = "1";
    UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDeviceId.hashCode() << 32) | tmSerial.hashCode());
    String uniqueId = deviceUuid.toString();
    return uniqueId;
}

and here the fork of the toolkit wich contains the port to 4.O,

https://github.com/jogibear9988/wpftoolkit

it's worked very well to me .

Git v2.19 introduces branch.sort config option (see branch.sort).

So git branch will sort by committer date (desc) by default with

# gitconfig
[branch]
    sort = -committerdate     # desc

script:

$ git config --global branch.sort -committerdate

Update:

So,

$ git branch
* dev
  master
  _

and

$ git branch -v
* dev    0afecf5 Merge branch 'oc' into dev
  master 652428a Merge branch 'dev'
  _      7159cf9 Merge branch 'bashrc' into dev

Look at how Runtime.getRuntime().exec() passes the String command to the ProcessBuilder. It uses a tokenizer and explodes the command into individual tokens, then invokes exec(String[] cmdarray, ......) which constructs a ProcessBuilder.

If you construct the ProcessBuilder with an array of strings instead of a single one, you'll get to the same result.

The ProcessBuilder constructor takes a String... vararg, so passing the whole command as a single String has the same effect as invoking that command in quotes in a terminal:

shell$ "command with args"

The simplest way to handle this case is by using getattr(). You can adapt this example to your needs:

from bs4 import BeautifulSoup

source_html = """
<span class="ratingsDisplay">
    <a class="ratingNumber" href="https://www.youtube.com/watch?v=oHg5SJYRHA0" target="_blank" rel="noopener">
        <span class="ratingsContent">3.7</span>
    </a>
</span>
"""

soup = BeautifulSoup(source_html, "lxml")
my_ratings = getattr(soup.find('span', {"class": "ratingsContent"}), "text", None)
print(my_ratings)

This will find the text element,"3.7", within the tag object <span class="ratingsContent">3.7</span> when it exists, however, default to NoneType when it does not.

getattr(object, name[, default])

Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise, AttributeError is raised.

I agree that it is not possible in general.

The only thing CSS3 can do (which helped in my case) is to select elements that have no children:

table td:empty
{
   background-color: white;
}

Or have any children (including text):

table td:not(:empty)
{
   background-color: white;
}

According to the jQuery official documentation

To create a HTML element, $("<div/>") or $("<div></div>") is preferred.

Then you can use either appendTo, append, before, after and etc,. to insert the new element to the DOM.

PS: jQuery Version 1.11.x

The following command will return a list of all packages directly related to Java. They will be in the format of java-<version>.

$ yum search java | grep 'java-'

If there are no available packages, then you may need to download a new repository to search through. I suggest taking a look at Dag Wieers' repo. After downloading it, try the above command again.

You will see at least one version of Java packages available for download. Depending on when you read this, the lastest available version may be different.

java-1.7.0-openjdk.x86_64

The above package alone will only install JRE. To also install javac and JDK, the following command will do the trick:

$ yum install java-1.7.0-openjdk*

These packages will be installing (as well as their dependencies):

java-1.7.0-openjdk.x86_64
java-1.7.0-openjdk-accessibility.x86_64
java-1.7.0-openjdk-demo.x86_64
java-1.7.0-openjdk-devel.x86_64
java-1.7.0-openjdk-headless.x86_64
java-1.7.0-openjdk-javadoc.noarch
java-1.7.0-openjdk-src.x86_64

I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({name: 'filter'})
export class Filter implements PipeTransform {
    transform(array: Array<Object>, filter: Object): any {
        let notAllKeysUndefined = false;
        let newArray = [];

        if(array.length > 0) {
            for (let k in filter){
                if (filter.hasOwnProperty(k)) {
                    if(filter[k] != undefined && filter[k] != '') {
                        for (let i = 0; i < array.length; i++) {
                            let filterRule = filter[k];

                            if(typeof filterRule === 'object') {
                                for(let fkey in filterRule) {
                                    if (filter[k].hasOwnProperty(fkey)) {
                                        if(filter[k][fkey] != undefined && filter[k][fkey] != '') {

                                                newArray.push(array[i]);
                                            }

                                        }
                                    }
                                }
                            } else {
                                if(this.shouldPushInArray(array[i][k], filter[k])) {
                                    newArray.push(array[i]);
                                }

                    }
                }
            }
            if(notAllKeysUndefined) {
                return newArray;
            }
        }

        return array;
    }

    private shouldPushInArray(item, filter) {
        if(typeof filter !== 'string') {
            item = item.toString();
            filter = filter.toString();
        }

        // Filter main logic
        item = item.toLowerCase();
        filter = filter.toLowerCase();
        if(item.indexOf(filter) !== -1) {
            return true;
        }
        return false;
    }
}

Returns the string the user entered; empty string if they hit Cancel:

    public static String InputBox(String caption, String prompt, String defaultText)
    {
        String localInputText = defaultText;
        if (InputQuery(caption, prompt, ref localInputText))

        }
        else
        {
            return "";
        }
    }

Returns the String as a ref parameter, returning true if they hit OK, or false if they hit Cancel:

Use - (Negative sign) along with position of element, example if 3rd element is to be removed use it as your_list[-3]

Input

my_list <- list(a = 3, b = 3, c = 4, d = "Hello", e = NA)
my_list
# $`a`
# [1] 3

# $b
# [1] 3

# $c
# [1] 4

# $d
# [1] "Hello"

# $e
# [1] NA

Remove single element from list

 my_list[-3]
 # $`a`
 # [1] 3

 # $b
 # [1] 3

 # $d
 # [1] "Hello"

 # $e
 [1] NA

Remove multiple elements from list

 my_list[c(-1,-3,-2)]
 # $`d`
 # [1] "Hello"

 # $e
 # [1] NA

 my_list[c(-3:-5)]
 # $`a`
 # [1] 3

 # $b
 # [1] 3

 my_list[-seq(1:2)]
 # $`c`
 # [1] 4

 # $d
 # [1] "Hello"

 # $e
 # [1] NA

So here is the brief summary for Bootstrap 4:

<div class="container-fluid px-0">
  <div class="row no-gutters">
    <div class="col-12">          //any cols you need
        ...
    </div>
  </div>
</div>

It works for me.

This worked for me

sudo apt-get install ca-certificates

then go into the certificates folder at

sudo cd /etc/ssl/certs

then you copy the ca-certificates.crt file into the /etc/pki/tls/certs

sudo cp ca-certificates.crt /etc/pki/tls/certs

if there is no tls/certs folder: create one and change permissions using chmod 777 -R folderNAME

Is this what you are after?

select * from tempdb..sysobjects
--for sql-server 2000 and later versions

select * from tempdb.sys.objects
--for sql-server 2005 and later versions

yes, using *arg passing args to a function will make python unpack the values in arg and pass it to the function.

so:

>>> def printer(*args):
 print args


>>> printer(2,3,4)
(2, 3, 4)
>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)
>>> 

From the docs:

from .. import scriptA

You can do this in packages, but not in scripts you run directly. From the link above:

Note that both explicit and implicit relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports.

If you create a script that imports A.B.B, you won't receive the ValueError.

CardView extends FrameLayout, so it support foreground attribute. Using foreground attribute can also add border easily.

layout as follows:

<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/link_card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:foreground="@drawable/bg_roundrect_ripple_light_border"
    app:cardCornerRadius="23dp"
    app:cardElevation="0dp">
</androidx.cardview.widget.CardView>

bg_roundrect_ripple_light_border.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/ripple_color_light">

        <shape android:shape="rectangle">
            <stroke
                android:width="0.5dp"
                android:color="#DDDDDD" />
            <corners android:radius="23dp" />
        </shape>
    </item>

    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <corners android:radius="23dp" />
            <solid android:color="@color/background" />
        </shape>
    </item>

</ripple>

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

Convert the value to a string, add a zero in front of it (so that it's two or tree characters), and get the last to characters:

right('0'+convert(varchar(2),Sort_Export_CSV),2)

For me worked: Right click on project > Properties > Project Faces > change Configuration from "custom" to "Default configuration for Apache Tomcat v7.0" > OK and then Run on Server option has appeared.

public static class Webdriver
{        
    public static void ExecuteJavaScript(string scripts)
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        js.ExecuteScript(scripts);
    }

    public static T ExecuteJavaScript<T>(string scripts)
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        return (T)js.ExecuteScript(scripts);
    }
}

In your code you can then do

string test = Webdriver.ExecuteJavaScript<string>(" return 'hello World'; ");
int test = Webdriver.ExecuteJavaScript<int>(" return 3; ");

Mine was here: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE"

The answers are great. If you want to give a chance to another clustering method you can use hierarchical clustering and see how data is splitting.

> set.seed(2)
> x=matrix(rnorm(50*2), ncol=2)
> hc.complete = hclust(dist(x), method="complete")
> plot(hc.complete)

Depending on how many classes you need you can cut your dendrogram as;

> cutree(hc.complete,k = 2)
 [1] 1 1 1 2 1 1 1 1 1 1 1 1 1 2 1 2 1 1 1 1 1 2 1 1 1
[26] 2 1 1 1 1 1 1 1 1 1 1 2 2 1 1 1 2 1 1 1 1 1 1 1 2

If you type ?cutree you will see the definitions. If your data set has three classes it will be simply cutree(hc.complete, k = 3). The equivalent for cutree(hc.complete,k = 2) is cutree(hc.complete,h = 4.9).

For me as a beginner in TypeScript, it was a problem in the getter and the setter of _var1.

class Point2{
    
    constructor(private _var1?: number, private y?: number){}

    set var1(num: number){
        this._var1 = num  // problem was here, it was this.var1 = num
    }
    get var1(){
        return this._var1 // this was return this.var1
    }
}

To hide those warnings, you could do this before your actual code.

import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
import tensorflow as tf

Just to keep it backward compatible I load Crockfords JSON-library from cloudflare CDN if no native JSON support is given (for simplicity using jQuery):

function winHasJSON(){
  json_data = JSON.stringify(obj);
  // ... (do stuff with json_data)
}
if(typeof JSON === 'object' && typeof JSON.stringify === 'function'){
  winHasJSON();
} else {
  $.getScript('//cdnjs.cloudflare.com/ajax/libs/json2/20121008/json2.min.js', winHasJSON)
}

If there are multiple columns with identical names, the solutions given here so far will remove all of the columns, which may not be what one is looking for. This may be the case if one is trying to remove duplicate columns except one instance. The example below clarifies this situation:

# make a df with duplicate columns 'x'
df = pd.DataFrame({'x': range(5) , 'x':range(5), 'y':range(6, 11)}, columns = ['x', 'x', 'y']) 


df
Out[495]: 
   x  x   y
0  0  0   6
1  1  1   7
2  2  2   8
3  3  3   9
4  4  4  10

# attempting to drop the first column according to the solution offered so far     
df.drop(df.columns[0], axis = 1) 
   y
0  6
1  7
2  8
3  9
4  10

As you can see, both Xs columns were dropped. Alternative solution:

column_numbers = [x for x in range(df.shape[1])]  # list of columns' integer indices

column_numbers .remove(0) #removing column integer index 0
df.iloc[:, column_numbers] #return all columns except the 0th column

   x  y
0  0  6
1  1  7
2  2  8
3  3  9
4  4  10

As you can see, this truly removed only the 0th column (first 'x').

I've made a mistake in the last my post. This is working example for how to pass additional argument in callback function:

function custom_func(p1,p2) {
    $.post(AJAX_FILE_PATH,{op:'dosomething',p1:p1},
        function(data){
            return function(){
                alert(data);
                alert(p2);
            }(data,p2)
        }
    );
    return false;
}

I found this question by the title. If anyone else is looking for the answer on how to just get the domain name, use the following environment variable.

System.Environment.UserDomainName

I'm aware that the author to the question mentions this, but I missed it at the first glance and thought someone else might do the same.

What the description of the question then ask for is the fully qualified domain name (FQDN).

}

When packing signed bytes into an int, each byte needs to be masked off because it is sign-extended to 32 bits (rather than zero-extended) due to the arithmetic promotion rule (described in JLS, Conversions and Promotions).

There's an interesting puzzle related to this described in Java Puzzlers ("A Big Delight in Every Byte") by Joshua Bloch and Neal Gafter . When comparing a byte value to an int value, the byte is sign-extended to an int and then this value is compared to the other int

byte[] bytes = (…)
if (bytes[0] == 0xFF) {
   // dead code, bytes[0] is in the range [-128,127] and thus never equal to 255
}

Note that all numeric types are signed in Java with exception to char being a 16-bit unsigned integer type.

#!/bin/sh

as most scripts do not need specific bash feature and should be written for sh.

Also, this makes scripts work on the BSDs, which do not have bash per default.

This ridiculous error message merely means there's a binding to an array that doesn't exist.

<option
  *ngFor="let option of setting.options"
  [value]="option"
  >{{ option }}
</option>

In the example above the value of setting.options is undefined. To fix, press F12 and open developer window. When the the get request returns the data look for the values to contain data.

If data exists, then make sure the binding name is correct

//was the property name correct? 
setting.properNamedOptions

If the data exists, is it an Array?

If the data doesn't exist then fix it on the backend.

There are situations where it matters.

If you pass AF_INET to socket() in Cygwin, your socket may or may not be randomly reset. Passing PF_INET ensures that the connection works right.

Cygwin is self-admittedly a huge mess for socket programming, but it is a real world case where AF_INET and PF_INET are not identical.

You're being mislead by output -- the second approach you're taking actually does what you want, you just aren't believing it. :)

>>> foo = 'baz "\\"'
>>> foo
'baz "\\"'
>>> print(foo)
baz "\"

Incidentally, there's another string form which might be a bit clearer:

>>> print(r'baz "\"')
baz "\"

<td><b>Field Label:</b><br>
    <select style='align:left; width:100%;' id='some_id' name='some_name'>
    <option hidden selected>Select one...</option>
    <option value='Value1'>OptLabel1</option>
    <option value='Value2'>OptLabel2</option>
    <option value='Value3'>OptLabel3</option></select>
</td>

Just put "hidden" on option you want to hide on dropdown list.

 * The cost to add or delete an element into a known location in the list 
   (i.e. if you have an iterator to the location) is O(1). If you don't 
   know the location, then you need to traverse the list to the location
   of deletion/insertion, which takes O(n) time. 

** The deletion cost is O(log n) for the minimum or maximum, O(n) for an
   arbitrary element.

I also wanted similar functionality where I have a File Input Control with display:none and a Button control where I wanted to trigger click event of File Input Control when I click on the button, below is the code to do so

<input type="button" (click)="fileInput.click()" class="btn btn-primary" value="Add From File">
<input type="file" style="display:none;" #fileInput/>

as simple as that and it's working flawlessly...

Your regex seems a bit too complex in my opinion. Also, remember that the dot is a special character meaning "any character". The following regex should work (note the escaped dots):

^.*\.(jpg|JPG|gif|GIF|doc|DOC|pdf|PDF)$

You can use a tool like Expresso to test your regular expressions.

Since we use tel: links on a site with a phone-icon on :before most solutions posted here introduces another problem.

I used the meta-tag:

<meta name="format-detection" content="telephone=no">

This combined with specifying tel: links site-wide where it should be linked!

Using css is really not an option as it hides relevant tel-links.

When you create an empty project, this line is commented in Gemfile. Just uncomment it and bundle!

Did you recently updated your eclipse android plugin (adt r17)? Then the following link might help:

How to fix the classdefnotfounderror with adt-17

Update: One year has passed since the question arose. I will keep the link, because even in 2013 it seem to help some people to solve the problem. But please take care what you are doing, see Erics comment below. Current ADT-Version is 22, I recommend using the most current version.

Please! please! please! DO NOT serialize data and place it into your database. Serialize can be used that way, but that's missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries. If you want your application to be portable to other languages, like let's say you find that you want to use Java for some portion of your app that it makes sense to use Java in, serialization will become a pain in the buttocks. You should always be able to query and modify data in the database without using a third party intermediary tool to manipulate data to be inserted.

it makes really difficult to maintain code, code with portability issues, and data that is it more difficult to migrate to other RDMS systems, new schema, etc. It also has the added disadvantage of making it messy to search your database based on one of the fields that you've serialized.

That's not to say serialize() is useless. It's not... A good place to use it may be a cache file that contains the result of a data intensive operation, for instance. There are tons of others... Just don't abuse serialize because the next guy who comes along will have a maintenance or migration nightmare.

A good example of serialize() and unserialize() could be like this:

$posts = base64_encode(serialize($_POST));
header("Location: $_SERVER[REQUEST_URI]?x=$posts");

Unserialize on the page

if($_GET['x']) {
   // unpack serialize and encoded URL
   $_POST = unserialize(base64_decode($_GET['x']));
}

Just wanted to share with you:
I happened to get this error after changing Digital Ocean machine (IP address). Apparently Gmail recognized it as a hacking attack. After following their directions, and approving the new IP address the code is back and running.

if the variable is a string

bool result = string.IsNullOrEmpty(variableToTest);

if you only have an object which may or may not contain a string then

bool result = string.IsNullOrEmpty(variableToTest as string);

np.convolve needs a flattened array as one of it's inputs, you can use numpy.ndarray.flatten() which is quite fast, find it here.

Here's a simple method:

public static boolean checkDatePattern(String padrao, String data) {
    try {
        SimpleDateFormat format = new SimpleDateFormat(padrao, LocaleUtils.DEFAULT_LOCALE);
        format.parse(data);
        return true;
    } catch (ParseException e) {
        return false;
    }
}

You've correctly diagnosed your problem, so good job. Once you call into your search code, the for loop just keeps right on going.

I'm a big fan of https://github.com/caolan/async, and it serves me well. Basically with it you'd end up with something like:

var async = require('async')
async.eachSeries(Object.keys(config), function (key, next){ 
  search(config[key].query, function(err, result) { // <----- I added an err here
    if (err) return next(err)  // <---- don't keep going if there was an error

    var json = JSON.stringify({
      "result": result
    });
    results[key] = {
      "result": result
    }
    next()    /* <---- critical piece.  This is how the forEach knows to continue to
                       the next loop.  Must be called inside search's callback so that
                       it doesn't loop prematurely.*/
  })
}, function(err) {
  console.log('iterating done');
}); 

I hope that helps!

You can also:

if (x & 1)
 itsOdd();
else
 itsEven();

Here is an update to Vadim Shender's clever code with tabular output:

import collections
import time
from functools import wraps

PROF_DATA = collections.defaultdict(list)

def profile(fn):
    @wraps(fn)
    def with_profiling(*args, **kwargs):
        start_time = time.time()
        ret = fn(*args, **kwargs)
        elapsed_time = time.time() - start_time
        PROF_DATA[fn.__name__].append(elapsed_time)
        return ret
    return with_profiling

Metrics = collections.namedtuple("Metrics", "sum_time num_calls min_time max_time avg_time fname")

def print_profile_data():
    results = []
    for fname, elapsed_times in PROF_DATA.items():
        num_calls = len(elapsed_times)
        min_time = min(elapsed_times)
        max_time = max(elapsed_times)
        sum_time = sum(elapsed_times)
        avg_time = sum_time / num_calls
        metrics = Metrics(sum_time, num_calls, min_time, max_time, avg_time, fname)
        results.append(metrics)
    total_time = sum([m.sum_time for m in results])
    print("\t".join(["Percent", "Sum", "Calls", "Min", "Max", "Mean", "Function"]))
    for m in sorted(results, reverse=True):
        print("%.1f\t%.3f\t%d\t%.3f\t%.3f\t%.3f\t%s" % (100 * m.sum_time / total_time, m.sum_time, m.num_calls, m.min_time, m.max_time, m.avg_time, m.fname))
    print("%.3f Total Time" % total_time)

You can use the function stat.desc from pastec package.

library(pastec)
stat.desc(x, BASIC =TRUE, NORMAL =TRUE)

you can find more about it from here: https://www.rdocumentation.org/packages/pastecs/versions/1.3.21/topics/stat.desc

Like it has been said few times, you need to change your selector to

$("input[name='bla[]']")

But I want to add, you have to use single or double quotes when using [] in selector.

I think that "\r\n" should work fine

There are a few ways to go about this. One option would be to use inputfile.read() instead of inputfile.readlines() - you'd need to write separate code to strip the first four lines, but if you want the final output as a single string anyway, this might make the most sense.

A second, simpler option would be to rejoin the strings after striping the first four lines with my_text = ''.join(my_text). This is a little inefficient, but if speed isn't a major concern, the code will be simplest.

Finally, if you actually want the output as a list of strings instead of a single string, you can just modify your data parser to iterate over the list. That might looks something like this:

def data_parser(lines, dic):
    for i, j in dic.iteritems():
        for (k, line) in enumerate(lines):
            lines[k] = line.replace(i, j)
    return lines

Or you can do it like as well:

<asp:DropDownList ID="ddl" runat="server"  AutoPostBack="true" onchange="javascript:CalcTotalAmt();" OnSelectedIndexChanged="ddl_SelectedIndexChanged"></asp:DropDownList>

This is what I use often:

git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force;

Note that it is good practice not to make changes to your local master/develop branch, but instead checkout to another branch for any change, with the branch name prepended by the type of change, e.g. feat/, chore/, fix/, etc. Thus you only need to pull changes, not push any changes from master. Same thing for other branches that others contribute to. So the above should only be used if you have happened to commit changes to a branch that others have committed to, and need to reset. Otherwise in future avoid pushing to a branch that others push to, instead checkout and push to the said branch via the checked out branch.

If you want to reset your local branch to the latest commit in the upstream branch, what works for me so far is:

Check your remotes, make sure your upstream and origin are what you expect, if not as expected then use git remote add upstream <insert URL>, e.g. of the original GitHub repo that you forked from, and/or git remote add origin <insert URL of the forked GitHub repo>.

git remote --verbose

git checkout develop;
git commit -m "Saving work.";
git branch saved-work;
git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force

On GitHub, you can also checkout the branch with the same name as the local one, in order to save the work there, although this isn't necessary if origin develop has the same changes as the local saved-work branch. I'm using the develop branch as an example, but it can be any existing branch name.

git add .
git commit -m "Reset to upstream/develop"
git push --force origin develop

Then if you need to merge these changes with another branch while where there are any conflicts, preserving the changes in develop, use:

git merge -s recursive -X theirs develop

While use

git merge -s recursive -X ours develop

to preserve branch_name's conflicting changes. Otherwise use a mergetool with git mergetool.

With all the changes together:

git commit -m "Saving work.";
git branch saved-work;
git checkout develop;
git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force;
git add .;
git commit -m "Reset to upstream/develop";
git push --force origin develop;
git checkout branch_name;
git merge develop;

Note that instead of upstream/develop you could use a commit hash, other branch name, etc. Use a CLI tool such as Oh My Zsh to check that your branch is green indicating that there is nothing to commit and the working directory is clean (which is confirmed or also verifiable by git status). Note that this may actually add commits compared to upstream develop if there is anything automatically added by a commit, e.g. UML diagrams, license headers, etc., so in that case, you could then pull the changes on origin develop to upstream develop, if needed.

I am not sure and not really trust $_SERVER['HTTP_HOST'] because it depend on header from client. In another way, if a domain requested by client is not mine one, they will not getting into my site because DNS and TCP/IP protocol point it to the correct destination. However I don't know if possible to hijack the DNS, network or even Apache server. To be safe, I define host name in environment and compare it with $_SERVER['HTTP_HOST'].

Add SetEnv MyHost domain.com in .htaccess file on root and add ths code in Common.php

if (getenv('MyHost')!=$_SERVER['HTTP_HOST']) {
  header($_SERVER['SERVER_PROTOCOL'].' 400 Bad Request');
  exit();
}

I include this Common.php file in every php page. This page doing anything required for each request like session_start(), modify session cookie and reject if post method come from different domain.

Is a simple MAYUS word. verify the log.

1. No, this doesn't mean network is slow.
2. No, this is not only false warning.

I have this problem on angular web applications after replace link https://fonts.googleapis.com/icon?family=Material+Icons in index.html to integrated version (npm install .... material-icons...). This works, but sometimes web application show that warning.

When warning is shown icons are not rendered for approximately 1 second, so user see badly rendered icons.

I don't have solution yet.

THE way is

:%s/pattern//gn

values()

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

values_list()

Returns a QuerySet that returns list of tuples, rather than model instances, when used as an iterable.

distinct()

distinct are used to eliminate the duplicate elements.

Example:

>>> list(Article.objects.values_list('id', flat=True)) # flat=True will remove the tuples and return the list   
[1, 2, 3, 4, 5, 6]

>>> list(Article.objects.values('id'))
[{'id':1}, {'id':2}, {'id':3}, {'id':4}, {'id':5}, {'id':6}]

Note that java11 now offers a new HTTP api HttpClient, which supports fully asynchronous operation, using java's CompletableFuture.

It also supports a synchronous version, with calls like send, which is synchronous, and sendAsync, which is asynchronous.

Example of an async request (taken from the apidoc):

   HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("https://example.com/"))
        .timeout(Duration.ofMinutes(2))
        .header("Content-Type", "application/json")
        .POST(BodyPublishers.ofFile(Paths.get("file.json")))
        .build();
   client.sendAsync(request, BodyHandlers.ofString())
        .thenApply(HttpResponse::body)
        .thenAccept(System.out::println);

My favourite is to extend jQuery with this tiny convenience:

$.fn.exists = function () {
    return this.length !== 0;
}

Used like:

$("#notAnElement").exists();

More explicit than using length.

When you get the width and height of a resized image Get width of a resized image after UIViewContentModeScaleAspectFit, you can resize your imageView:

imageView.frame = CGRectMake(0, 0, resizedWidth, resizedHeight);
imageView.center = imageView.superview.center;

I haven't checked if it works, but I think all should be OK

To move/copy from one bucket to another or the same bucket I use s3cmd tool and works fine. For instance:

s3cmd cp --recursive s3://bucket1/directory1 s3://bucket2/directory1
s3cmd mv --recursive s3://bucket1/directory1 s3://bucket2/directory1

Try this

SELECT CAST(DataField AS time(7)) AS 'time'

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/
