The trick is to represent the algorithms state, which is an integer multi-set, as a compressed stream of "increment counter"="+" and "output counter"="!" characters. For example, the set {0,3,3,4} would be represented as "!+++!!+!", followed by any number of "+" characters. To modify the multi-set you stream out the characters, keeping only a constant amount decompressed at a time, and make changes inplace before streaming them back in compressed form.

Details

We know there are exactly 10^6 numbers in the final set, so there are at most 10^6 "!" characters. We also know that our range has size 10^8, meaning there are at most 10^8 "+" characters. The number of ways we can arrange 10^6 "!"s amongst 10^8 "+"s is (10^8 + 10^6) choose 10^6, and so specifying some particular arrangement takes ~0.965 MiB` of data. That'll be a tight fit.

We can treat each character as independent without exceeding our quota. There are exactly 100 times more "+" characters than "!" characters, which simplifies to 100:1 odds of each character being a "+" if we forget that they are dependent. Odds of 100:101 corresponds to ~0.08 bits per character, for an almost identical total of ~0.965 MiB (ignoring the dependency has a cost of only ~12 bits in this case!).

The simplest technique for storing independent characters with known prior probability is Huffman coding. Note that we need an impractically large tree (A huffman tree for blocks of 10 characters has an average cost per block of about 2.4 bits, for a total of ~2.9 Mib. A huffman tree for blocks of 20 characters has an average cost per block of about 3 bits, which is a total of ~1.8 MiB. We're probably going to need a block of size on the order of a hundred, implying more nodes in our tree than all the computer equipment that has ever existed can store.). However, ROM is technically "free" according to the problem and practical solutions that take advantage of the regularity in the tree will look essentially the same.

Pseudo-code

• Have a sufficiently large huffman tree (or similar block-by-block compression data) stored in ROM
• Start with a compressed string of 10^8 "+" characters.
• To insert the number N, stream out the compressed string until N "+" characters have gone past then insert a "!". Stream the recompressed string back over the previous one as you go, keeping a constant amount of buffered blocks to avoid over/under-runs.
• Repeat one million times: [input, stream decompress>insert>compress], then decompress to output

Java does not have the exact syntax but as of JDK-8, we have the Optional API with various methods at our disposal. So, the C# version with the use of null conditional operator:

return person?.getName()?.getGivenName(); 

can be written as follows in Java with the Optional API:

 return Optional.ofNullable(person)
                .map(e -> e.getName())
                .map(e -> e.getGivenName())
                .orElse(null);

if any of person, getName or getGivenName is null then null is returned.

I found this wonderful mapping script (mapper.js) that I have used in the past. What's different about it is you can hover over the map or a link on your page to make the map area highlight. Sadly it's written in javascript and requires a lot of in-line coding in the HTML - I would love to see this script ported over to jQuery :P

Also, check out all the demos! I think this example could almost be made into a simple online game (without using flash) - make sure you click on the different camera angles.

Adding custom rules is useful if you create a jQuery widget that requires custom CSS (such as extending the existing jQueryUI CSS framework for your particular widget). This solution builds on Taras's answer (the first one above).

Assuming your HTML markup has a button with an id of "addrule" and a div with an id of "target" containing some text:

jQuery code:

$( "#addrule" ).click(function () { addcssrule($("#target")); });

function addcssrule(target) 
{ 
var cssrules =  $("<style type='text/css'> </style>").appendTo("head");

cssrules.append(".redbold{ color:#f00; font-weight:bold;}"); 
cssrules.append(".newfont {font-family: arial;}"); 
target.addClass("redbold newfont");     
}       

The advantage of this approach is that you can reuse variable cssrules in your code to add or subtract rules at will. If cssrules is embedded in a persistent object such as a jQuery widget you have a persistent local variable to work with.

try this is your activity onCreate:

ScrollView sView = (ScrollView)findViewById(R.id.deal_web_view_holder);
// Hide the Scollbar
sView.setVerticalScrollBarEnabled(false);
sView.setHorizontalScrollBarEnabled(false);

http://developer.android.com/reference/android/view/View.html#setVerticalScrollBarEnabled%28boolean%29

just need putting the datatype of the column in the datasource

dataSource: {
      data: empModel.Value,
      pageSize: 10,
      schema:  {
                model: {
                    fields: {
                        DOJ: { type: "date" }
                            }
                       }
               }  
           }

and then your statement column:

 columns: [
    {
        field: "Name",
        width: 90,
        title: "Name"
    },

    {
        field: "DOJ",
        width: 90,
        title: "DOJ",
        type: "date",
        format:"{0:MM-dd-yyyy}" 
    }
]

To get rid of vertical padding for a single line label I did:

// I have a category method setFrameHeight; you'll likely need to modify the frame.
[label setFrameHeight:font.pointSize];

OR, without the category, use:

CGRect frame = label.frame;
frame.size.height = font.pointSize;
label.frame = frame;

there are better ways to do it as mentioned on android developer sites http://developer.android.com/guide/topics/location/strategies.html

thead {
  position: fixed;
  height: 10px; /* This is whatever height you want */
}
  tbody {
  position: fixed;
  margin-top: 10px; /* This has to match the height of thead */
  height: 300px; /* This is whatever height you want */
}

You need to float the divs in required direction eg left or right.

For me, I just did a CTRL+C and YES .
And I restart by

ionic serve 

This works for me.

I had the same problem quite a few times. It happened especially when i tried to paste a few lines of code from an editor online, the spaces are not registered properly as 'tabs' or 'spaces'.

However the fix was quite simple. I just had to remove the spacing across all the lines of code in that specific set and space it again with the tabs correctly. This fixed my problem.

Use this CSS for Modal and modal-dialog

.modal{
    pointer-events: none;
}

.modal-dialog{
    pointer-events: all;
 }

This can resolve your problem in Modal

I had the same issue, but the other answers only supplied one part of the solution.

The solution is two fold:

Remove the 64bit from the Register.

• c:\windows\system32\regsvr32.exe /U <file.dll>
• This will not remove references to other copied of the dll in other folders.

or

• Find the key called HKEY_CLASSES_ROOT\CLSID{......}\InprocServer32. This key will have the filename of the DLL as its default value.
• I removed the HKEY_CLASSES_ROOT\CLSID{......} folder.

Register it as 32bit:

• C:\Windows\SysWOW64\regsvr32 <file.dll>

Registering it as 32bit without removing the 64bit registration does not resolve my issue.

Hopefully this would get you started

See it live on http://ideone.com/l23He (using stdin)

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

const char* getfield(char* line, int num)
{
    const char* tok;
    for (tok = strtok(line, ";");
            tok && *tok;
            tok = strtok(NULL, ";\n"))
    {
        if (!--num)
            return tok;
    }
    return NULL;
}

int main()
{
    FILE* stream = fopen("input", "r");

    char line[1024];
    while (fgets(line, 1024, stream))
    {
        char* tmp = strdup(line);
        printf("Field 3 would be %s\n", getfield(tmp, 3));
        // NOTE strtok clobbers tmp
        free(tmp);
    }
}

Output:

Field 3 would be nazwisko
Field 3 would be Kowalski
Field 3 would be Nowak

I'm late to the party, but if you want to do this to an arbitrary element using only CSS, without messing around with positioning, overlay divs etc., you can use an inset box shadow:

box-shadow: inset 0px 0px 0 2000px rgba(0,0,0,0.5);

This will work on any element smaller than 4000 pixels long or wide.

example: http://jsfiddle.net/jTwPc/

There are two major categories of types in Java: primitive and reference. Variables declared of a primitive type store values; variables declared of a reference type store references.

String x = null;

In this case, the initialization statement declares a variables “x”. “x” stores String reference. It is null here. First of all, null is not a valid object instance, so there is no memory allocated for it. It is simply a value that indicates that the object reference is not currently referring to an object.

http://php.net/manual/en/function.unlink.php

Unlink can safely remove a single file; just make sure the file you are removing it actually a file and not a directory ('.' or '..')

if (is_file($filepath))
  {
    unlink($filepath);
  }

Why don't you just use the database diagram functionality built into SQL Server?

Single precision number uses 32 bits, with the MSB being sign bit, whereas double precision number uses 64bits, MSB being sign bit

Single precision

SEEEEEEEEFFFFFFFFFFFFFFFFFFFFFFF.(SIGN+EXPONENT+SIGNIFICAND)

Double precision:

SEEEEEEEEEEEFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.(SIGN+EXPONENT+SIGNIFICAND)

Yes. For that ensure that you declare the worksheet

For example

Previous Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet3")

    Debug.Print ws.Cells(23, 4).Value
End Sub

New Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet4")

    Debug.Print ws.Cells(23, 4).Value
End Sub

A character set is a subset of all written glyphs. A character encoding specifies how those characters are mapped to numeric values. Some character encodings, like UTF-8 and UTF-16, can encode any character in the Universal Character Set. Others, like US-ASCII or ISO-8859-1 can only encode a small subset, since they use 7 and 8 bits per character, respectively. Because many standards specify both a character set and a character encoding, the term "character set" is often substituted freely for "character encoding".

A collation comprises rules that specify how characters can be compared for sorting. Collations rules can be locale-specific: the proper order of two characters varies from language to language.

Choosing a character set and collation comes down to whether your application is internationalized or not. If not, what locale are you targeting?

In order to choose what character set you want to support, you have to consider your application. If you are storing user-supplied input, it might be hard to foresee all the locales in which your software will eventually be used. To support them all, it might be best to support the UCS (Unicode) from the start. However, there is a cost to this; many western European characters will now require two bytes of storage per character instead of one.

Choosing the right collation can help performance if your database uses the collation to create an index, and later uses that index to provide sorted results. However, since collation rules are often locale-specific, that index will be worthless if you need to sort results according to the rules of another locale.

The problem was that I used ajax to post the message to the server, when I used a direct link to download the file everything worked fine.

I used this other Stackoverflow Q&A material instead, it worked great for me:

• Ajax File Download using Jquery, PHP

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

I have created an open-source hackable local testing server that you can get running in minutes. You can create new API's, define your own response and hack it in any ways you wish to.

Another poster suggested

ls -l | head -2 | tail -1

but if you pipe head into tail, it looks like everything up to line N is processed twice.

Piping tail into head

ls -l | tail -n +2 | head -n1

would be more efficient?

echo $'Create the snapshots\nSnapshot created\n'

Another option is an interesting open source project called ScriptCS. It uses some crafty techniques to allow you a development experience outside of Visual Studio while still being able to leverage NuGet to manage your dependencies. It's free, very easy to install using Chocolatey. You can check it out here http://scriptcs.net.

Another cool feature it has is the REPL from the command line. Which allows you to do stuff like this:

C:\> scriptcs
scriptcs (ctrl-c or blank to exit)

> var message = "Hello, world!";
> Console.WriteLine(message);
Hello, world!
> 

C:\>

You can create C# utility "scripts" which can be anything from small system tasks, to unit tests, to full on Web APIs. In the latest release I believe they're also allowing for hosting the runtime in your own apps.

Check out it development on the GitHub page too https://github.com/scriptcs/scriptcs

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

You can just use css :

#id_fieldname, label[for="id_fieldname"] {_x000D_
  position: absolute;_x000D_
  display: none_x000D_
}

This will make the field and its label invisible.

One of the good things about handle.exe is that you can run it as a subprocess and parse the output.

We do this in our deployment script - works like a charm.

Unfortunately, vars files do not have include statements.

You can either put all the vars into the definitions dictionary, or add the variables as another dictionary in the same file.

If you don't want to have them in the same file, you can include them at the playbook level by adding the vars file at the start of the play:

---
- hosts: myhosts

  vars_files:
    - default_step.yml

or in a task:

---
- hosts: myhosts

  tasks:
    - name: include default step variables
      include_vars: default_step.yml

You can create a custom collector that convert a stream to array.

public static <T> Collector<T, ?, T[]> toArray( IntFunction<T[]> converter )
{
    return Collectors.collectingAndThen( 
                  Collectors.toList(), 
                  list ->list.toArray( converter.apply( list.size() ) ) );
}

and a quick use

List<String> input = Arrays.asList( ..... );

String[] result = input.stream().
         .collect( CustomCollectors.**toArray**( String[]::new ) );

you can add security provider by editing java.security by adding security.provider.=org.bouncycastle.jce.provider.BouncyCastleProvider

or add a line in your top of your class

Security.addProvider(new BouncyCastleProvider());

you can use below line to specify provider while specifying algorithms

Cipher cipher = Cipher.getInstance("AES", "SunJCE");

if you are using other provider like Bouncy Castle then

Cipher cipher =  Cipher.getInstance("AES", "BC");

I answered a virtually identical question just the other day: Save CSV files into mysql database

MySQL has a feature LOAD DATA INFILE, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.

Simple example:

<?php
$query = <<<eof
    LOAD DATA INFILE '$fileName'
     INTO TABLE tableName
     FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
     LINES TERMINATED BY '\n'
    (field1,field2,field3,etc)
eof;

$db->query($query);
?>

It's as simple as that.

No loops, no fuss. And much much quicker than parsing it in PHP.

MySQL manual page here: http://dev.mysql.com/doc/refman/5.1/en/load-data.html

Hope that helps

Given your container width 600px.

If you want only bigger images than that to fit inside, add: CSS:

#ImageContainer img {
    max-width: 600px;
}

If you want ALL images to take the avaiable (600px) space:

#ImageContainer img {
    width: 600px;
}

Because break cannot be used to break out of an if - it can only break out of loops. That's the way Python (and most other languages) are specified to behave.

What are you trying to do? Perhaps you should use sys.exit() or return instead?

If document.write('<\script ...') isn't working, try document.createElement('script')...

Other than that, you should be worried about the type of website you're making - do you really think its a good idea to include .js files from .js files?

Folks above hit the right notes for storage, though if you also need to consider any PII data that needs to be stored then you can also stash into the keychain using something like https://github.com/oblador/react-native-keychain since ASyncStorage is unencrypted. It can be applied as part of the persist configuration in something like redux-persist.

If your host is using suPHP, you can try creating a php.ini file in the same folder as the script and adding:

allow_url_fopen = On

(you can determine this by creating a file and checking which user it was created under: if you, it's suPHP, if "apache/nobody" or not you, then it's a normal PHP mode. You can also make a script

<?php
echo `id`;
?>

To give the same information, assuming shell_exec is not a disabled function)

ALTERNATIVE FOR LINE-BY-LINE SCROLLING

Ctrl + Shift + Up Arrow or Down Arrow

Unlike Shift + Page Up or Page Down, which scrolls the entire page, this will help with a smoother line-by-line scrolling, which is exactly what I was looking for.

What's wrong with transforming the version string into a tuple and going from there? Seems elegant enough for me

>>> (2,3,1) < (10,1,1)
True
>>> (2,3,1) < (10,1,1,1)
True
>>> (2,3,1,10) < (10,1,1,1)
True
>>> (10,3,1,10) < (10,1,1,1)
False
>>> (10,3,1,10) < (10,4,1,1)
True

@kindall's solution is a quick example of how good the code would look.

supervised learning

supervised learning is where we know the output of the raw input, i.e the data is labelled so that during the training of machine learning model it will understand what it need to detect in the give output, and it will guide the system during the training to detect the pre-labelled objects on that basis it will detect the similar objects which we have provided in training.

Here the algorithms will know what's the structure and pattern of data. Supervised learning is used for classification

As an example, we can have a different objects whose shapes are square, circle, trianle our task is to arrange the same types of shapes the labelled dataset have all the shapes labelled, and we will train the machine learning model on that dataset, on the based of training dateset it will start detecting the shapes.

Un-supervised learning

Unsupervised learning is a unguided learning where the end result is not known, it will cluster the dataset and based on similar properties of the object it will divide the objects on different bunches and detect the objects.

Here algorithms will search for the different pattern in the raw data, and based on that it will cluster the data. Un-supervised learning is used for clustering.

As an example, we can have different objects of multiple shapes square, circle, triangle, so it will make the bunches based on the object properties, if a object has four sides it will consider it square, and if it have three sides triangle and if no sides than circle, here the the data is not labelled, it will learn itself to detect the various shapes

Hmm, this seems to be a bit of an old question, but since I've been messing about with Doxygen configuration last few days, while my head's still full of current info let's have a stab at it -

I think the previous answers almost have it:

The missing option is to add COLLABORATION_GRAPH = YES in the Doxyfile. I assume you can do the equivalent thing somewhere in the doxywizard GUI (I don't use doxywizard).

So, as a more complete example, typical "Doxyfile" options related to UML output that I tend to use are:

EXTRACT_ALL          = YES
CLASS_DIAGRAMS      = YES
HIDE_UNDOC_RELATIONS = NO
HAVE_DOT             = YES
CLASS_GRAPH          = YES
COLLABORATION_GRAPH  = YES
UML_LOOK             = YES
UML_LIMIT_NUM_FIELDS = 50
TEMPLATE_RELATIONS   = YES
DOT_GRAPH_MAX_NODES  = 100
MAX_DOT_GRAPH_DEPTH  = 0
DOT_TRANSPARENT      = YES

These settings will generate both "inheritance" (CLASS_GRAPH=YES) and "collaboration" (COLLABORATION_GRAPH=YES) diagrams.

Depending on your target for "deployment" of the doxygen output, setting DOT_IMAGE_FORMAT = svg may also be of use. With svg output the diagrams are "scalable" instead of the fixed resolution of bitmap formats such as .png. Apparently, if viewing the output in browsers other than IE, there is also INTERACTIVE_SVG = YES which will allow "interactive zooming and panning" of the generated svg diagrams. I did try this some time ago, and the svg output was very visually attractive, but at the time, browser support for svg was still a bit inconsistent, so hopefully that situation may have improved lately.

As other comments have mentioned, some of these settings (DOT_GRAPH_MAX_NODES in particular) do have potential performance impacts, so YMMV.

I tend to hate "RTFM" style answers, so apologies for this sentence, but in this case the Doxygen documentation really is your friend, so check out the Doxygen docs on the above mentioned settings- last time I looked you can find the details at http://www.doxygen.nl/manual/config.html.

You can use one commandline with two commands (gs, convert) connected through a pipe, if the first command can write its output to stdout, and if the second one can read its input from stdin.

1. Luckily, gs can write to stdout (... -o %stdout ...).
2. Luckily, convert can read from stdin (convert -background transparent - output.png).

Problem solved:

• GS used for alpha channel handling a special image,
• convert used for creating transparent background,
• pipe used to avoid writing out a temp file on disk.

Complete solution:

gs -sDEVICE=pngalpha       \
   -o %stdout              \
   -r144 cover.pdf         \
   |                       \
convert                    \
   -background transparent \
   -                       \
    cover.png

Update

If you want to have a separate PNG per PDF page, you can use the %d syntax:

gs -sDEVICE=pngalpha -o file-%03d.png -r144 cover.pdf

This will create PNG files named page-000.png, page-001.png, ... (Note that the %d-counting is zero-based -- file-000.png corresponds to page 1 of the PDF, 001 to page 2...

Or, if you want to keep your transparent background, for a 100-page PDF, do

for i in {1..100}; do        \
                             \
  gs -sDEVICE=pngalpha       \
     -dFirstPage="${i}"      \
     -dLastPage="${i}"       \
     -o %stdout              \
     -r144 input.pdf         \
     |                       \
  convert                    \
     -background transparent \
     -                       \
      page-${i}.png ;        \
                             \
done

The way I use a yes/no prompt is:

If MsgBox("Are you sure?", MsgBoxStyle.YesNo) <> MsgBoxResults.Yes Then
    Exit Sub
End If

I'm using Java 1.8 and JAXB 2.3.1

First, be sure to be using java 1.8 in pom.xml

<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

Then in source code I used: (the key was the internal part)

// remove standalone=yes
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
marshaller.setProperty("com.sun.xml.internal.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

Operators                           Overloadability

+, -, *, /, %, &, |, <<, >>         All C# binary operators can be overloaded.

+, -, !,  ~, ++, --, true, false    All C# unary operators can be overloaded.

==, !=, <, >, <= , >=               All relational operators can be overloaded, 
                                    but only as pairs.

&&, ||                  They can't be overloaded

() (Conversion operator)        They can't be overloaded

+=, -=, *=, /=, %=                  These compound assignment operators can be 
                                    overloaded. But in C#, these operators are
                                    automatically overloaded when the respective
                                    binary operator is overloaded.

=, . , ?:, ->, new, is, as, sizeof  These operators can't be overloaded

    [ ]                             Can be overloaded but not always!

Source of the information

For bracket:

public Object this[int index]
{

}

BUT

The array indexing operator cannot be overloaded; however, types can define indexers, properties that take one or more parameters. Indexer parameters are enclosed in square brackets, just like array indices, but indexer parameters can be declared to be of any type (unlike array indices, which must be integral).

From MSDN

One point not pointed out yet, is the speed. I know it's an old answered question, but I think this deserves direct comment/answer:

They would seem to be redundant as the same can be done with derived tables

When I used CTE the very first time I was absolutely stunned by it's speed. It was a case like from a textbook, very suitable for CTE, but in all ocurences I ever used CTE, there was a significant speed gain. My first query was complex with derived tables, taking long minutes to execute. With CTE it took fractions of seconds and left me shocked, that it is even possible.

This set of utilities to work with the Size abstraction in Android.

It contains a class SizeFromDisplay.java You can use it like this:

ISize size = new SizeFromDisplay(getWindowManager().getDefaultDisplay());
size.width();
size.hight();

This would replicate exactly perl's chomp (minus behavior on arrays) for "\n" line terminator:

def chomp(x):
    if x.endswith("\r\n"): return x[:-2]
    if x.endswith("\n") or x.endswith("\r"): return x[:-1]
    return x

(Note: it does not modify string 'in place'; it does not strip extra trailing whitespace; takes \r\n in account)

Best way to solve this as per my opinion is Using "ignoreReadonly".

First make the input field readonly then add ignoreReadonly:true. This will make sure that even if the text field is readonly , popup will show.

$('#txtStartDate').datetimepicker({
            locale: "da",
            format: "DD/MM/YYYY",
            ignoreReadonly: true
        });
        $('#txtEndDate').datetimepicker({
            locale: "da",
            useCurrent: false,
            format: "DD/MM/YYYY",
            ignoreReadonly: true
        });
});

The keyword virtual tells the compiler it should not perform early binding. Instead, it should automatically install all the mechanisms necessary to perform late binding. To accomplish this, the typical compiler1 creates a single table (called the VTABLE) for each class that contains virtual functions.The compiler places the addresses of the virtual functions for that particular class in the VTABLE. In each class with virtual functions,it secretly places a pointer, called the vpointer (abbreviated as VPTR), which points to the VTABLE for that object. When you make a virtual function call through a base-class pointer the compiler quietly inserts code to fetch the VPTR and look up the function address in the VTABLE, thus calling the correct function and causing late binding to take place.

You would need to always consider the state of all checkboxes!

You could increase or decrease a number on checking or unchecking, but imagine the site loads with three of them checked.

So you always need to check all of them:

<script type="text/javascript">
<!--
function showMe (it, box) {
  // consider all checkboxes with same name
  var checked = amountChecked(box.name);

  var vis = (checked >= 3) ? "block" : "none";
  document.getElementById(it).style.display = vis;
}

function amountChecked(name) {
  var all = document.getElementsByName(name);

  // count checked
  var result = 0;
  all.forEach(function(el) {
    if (el.checked) result++;
  });

  return result;
}
//-->
</script>

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();
}

git remote manpage is pretty straightforward:

• https://www.kernel.org/pub/software/scm/git/docs/git-remote.html

Use

Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream

Then do:    
$ git remote add upstream https://github.com/Foo/repos.git

or just update the URL directly:

$ git remote set-url upstream https://github.com/Foo/repos.git

or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).

...
[remote "upstream"]
    fetch = +refs/heads/*:refs/remotes/upstream/*
    url = https://github.com/foo/repos.git
...

remote: prefer subcommand name 'remove' to 'rm'

All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

1. Try this 2. and change the condition to "WINTER" and you will wonder:

public static void main(String[] args) {
  Season.add("Frühling");
  Season.add("Sommer");
  Season.add("Herbst");
  Season.add("WINTER");
  for (String s : Season) {
   if(!s.equals("Sommer")) {
    System.out.println(s);
    continue;
   }
   Season.remove("Frühling");
  }
 }

Consider the following scenario:

public class Car {
  @Inject
  private Engine engine;  

  public Car() {
    engine.initialize();  
  }
  ...
}

Since Car has to be instantiated prior to field injection, the injection point engine is still null during the execution of the constructor, resulting in a NullPointerException.

This problem can be solved either by JSR-330 Dependency Injection for Java constructor injection or JSR 250 Common Annotations for the Java @PostConstruct method annotation.

@PostConstruct

JSR-250 defines a common set of annotations which has been included in Java SE 6.

The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization. This method MUST be invoked before the class is put into service. This annotation MUST be supported on all classes that support dependency injection.

JSR-250 Chap. 2.5 javax.annotation.PostConstruct

The @PostConstruct annotation allows for the definition of methods to be executed after the instance has been instantiated and all injects have been performed.

public class Car {
  @Inject
  private Engine engine;  

  @PostConstruct
  public void postConstruct() {
    engine.initialize();  
  }
  ...
} 

Instead of performing the initialization in the constructor, the code is moved to a method annotated with @PostConstruct.

The processing of post-construct methods is a simple matter of finding all methods annotated with @PostConstruct and invoking them in turn.

private  void processPostConstruct(Class type, T targetInstance) {
  Method[] declaredMethods = type.getDeclaredMethods();

  Arrays.stream(declaredMethods)
      .filter(method -> method.getAnnotation(PostConstruct.class) != null) 
      .forEach(postConstructMethod -> {
         try {
           postConstructMethod.setAccessible(true);
           postConstructMethod.invoke(targetInstance, new Object[]{});
        } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException ex) {      
          throw new RuntimeException(ex);
        }
      });
}

The processing of post-construct methods has to be performed after instantiation and injection have been completed.

If you want to append to the lists of each key inside a dictionary, you can append new values to them using + operator (tested in Python 3.7):

mydict = {'a':[], 'b':[]}
print(mydict)
mydict['a'] += [1,3]
mydict['b'] += [4,6]
print(mydict)
mydict['a'] += [2,8]
print(mydict)

and the output:

{'a': [], 'b': []}
{'a': [1, 3], 'b': [4, 6]}
{'a': [1, 3, 2, 8], 'b': [4, 6]}

mydict['a'].extend([1,3]) will do the job same as + without creating a new list (efficient way).

copied from that link, I had the same problem and this solved the problem, after we add password for the database, we need to add -p (password based login) then enter the password else will return this error.

mysql -u root -p

The problem occurs because webpack-dev-server 2.4.4 adds a host check. You can disable it by adding this to your webpack config:

 devServer: {
    compress: true,
    disableHostCheck: true,   // That solved it

 }      

EDIT: Please note, this fix is insecure.

Please see the following answer for a secure solution: https://stackoverflow.com/a/43621275/5425585

you can also do in this way using input-group

If you want to use JDKs downloaded from Oracle's site, what worked for me (using Mint) is using update-alternatives:

1. I downloaded the JDK and extracted it just anywhere, for example in /home/aqeel/development/jdk/jdk1.6.0_35

2. I ran:

   sudo update-alternatives --install /usr/bin/java java /home/aqeel/development/jdk/jdk1.6.0_35/bin/java 1
   

   Now you can execute sudo update-alternatives --config java and choose your java version.

3. This doesn't set the JAVA_HOME variable, which I wanted configured, so I just added it to my ~/.bashrc, including an export JAVA_HOME="/home/aqeel/development/jdk/jdk1.6.0_35" statement

Now, I had two JDKs downloaded (let's say the second has been extracted to /home/aqeel/development/jdk/jdk-10.0.1).

How can we change the JAVA_HOME dynamically based on the current java being used?

My solution is not very elegant, I'm pretty sure there are better options out there, but anyway:

4. To change the JAVA_HOME dynamically based on the chosen java alternative, I added this snippet to the ~/.bashrc:

   export JAVA_HOME=$(update-alternatives --query java | grep Value: | awk -F'Value: ' '{print $2}' | awk -F'/bin/java' '{print $1}')
   

Finally (this is out of the scope) if you have to change the java version constantly, you might want to consider:

5. Adding an alias to your ~./bash_aliases:

   alias change-java="sudo update-alternatives --config java"
   

(You might have to create the file and maybe uncomment the section related to this in ~/.bashrc)

try setting this

CATALINA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"

in {$tomcat-folder}\bin\setenv.sh (create it if necessary).

See http://www.mkyong.com/tomcat/tomcat-javalangoutofmemoryerror-permgen-space/ for more details.

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.

Compatible answer

There are a lot of different ways to do this in bash.

However, it's important to first note that bash has many special features (so-called bashisms) that won't work in any other shell.

In particular, arrays, associative arrays, and pattern substitution, which are used in the solutions in this post as well as others in the thread, are bashisms and may not work under other shells that many people use.

For instance: on my Debian GNU/Linux, there is a standard shell called dash; I know many people who like to use another shell called ksh; and there is also a special tool called busybox with his own shell interpreter (ash).

Requested string

The string to be split in the above question is:

IN="[email protected];[email protected]"

I will use a modified version of this string to ensure that my solution is robust to strings containing whitespace, which could break other solutions:

IN="[email protected];[email protected];Full Name <[email protected]>"

Split string based on delimiter in bash (version >=4.2)

In pure bash, we can create an array with elements split by a temporary value for IFS (the input field separator). The IFS, among other things, tells bash which character(s) it should treat as a delimiter between elements when defining an array:

IN="[email protected];[email protected];Full Name <[email protected]>"

# save original IFS value so we can restore it later
oIFS="$IFS"
IFS=";"
declare -a fields=($IN)
IFS="$oIFS"
unset oIFS

In newer versions of bash, prefixing a command with an IFS definition changes the IFS for that command only and resets it to the previous value immediately afterwards. This means we can do the above in just one line:

IFS=\; read -a fields <<<"$IN"
# after this command, the IFS resets back to its previous value (here, the default):
set | grep ^IFS=
# IFS=$' \t\n'

We can see that the string IN has been stored into an array named fields, split on the semicolons:

set | grep ^fields=\\\|^IN=
# fields=([0]="[email protected]" [1]="[email protected]" [2]="Full Name <[email protected]>")
# IN='[email protected];[email protected];Full Name <[email protected]>'

(We can also display the contents of these variables using declare -p:)

declare -p IN fields
# declare -- IN="[email protected];[email protected];Full Name <[email protected]>"
# declare -a fields=([0]="[email protected]" [1]="[email protected]" [2]="Full Name <[email protected]>")

Note that read is the quickest way to do the split because there are no forks or external resources called.

Once the array is defined, you can use a simple loop to process each field (or, rather, each element in the array you've now defined):

# `"${fields[@]}"` expands to return every element of `fields` array as a separate argument
for x in "${fields[@]}" ;do
    echo "> [$x]"
    done
# > [[email protected]]
# > [[email protected]]
# > [Full Name <[email protected]>]

Or you could drop each field from the array after processing using a shifting approach, which I like:

while [ "$fields" ] ;do
    echo "> [$fields]"
    # slice the array 
    fields=("${fields[@]:1}")
    done
# > [[email protected]]
# > [[email protected]]
# > [Full Name <[email protected]>]

And if you just want a simple printout of the array, you don't even need to loop over it:

printf "> [%s]\n" "${fields[@]}"
# > [[email protected]]
# > [[email protected]]
# > [Full Name <[email protected]>]

Update: recent bash >= 4.4

In newer versions of bash, you can also play with the command mapfile:

mapfile -td \; fields < <(printf "%s\0" "$IN")

This syntax preserve special chars, newlines and empty fields!

If you don't want to include empty fields, you could do the following:

mapfile -td \; fields <<<"$IN"
fields=("${fields[@]%$'\n'}")   # drop '\n' added by '<<<'

With mapfile, you can also skip declaring an array and implicitly "loop" over the delimited elements, calling a function on each:

myPubliMail() {
    printf "Seq: %6d: Sending mail to '%s'..." $1 "$2"
    # mail -s "This is not a spam..." "$2" </path/to/body
    printf "\e[3D, done.\n"
}

mapfile < <(printf "%s\0" "$IN") -td \; -c 1 -C myPubliMail

(Note: the \0 at end of the format string is useless if you don't care about empty fields at end of the string or they're not present.)

mapfile < <(echo -n "$IN") -td \; -c 1 -C myPubliMail

# Seq:      0: Sending mail to '[email protected]', done.
# Seq:      1: Sending mail to '[email protected]', done.
# Seq:      2: Sending mail to 'Full Name <[email protected]>', done.

Or you could use <<<, and in the function body include some processing to drop the newline it adds:

myPubliMail() {
    local seq=$1 dest="${2%$'\n'}"
    printf "Seq: %6d: Sending mail to '%s'..." $seq "$dest"
    # mail -s "This is not a spam..." "$dest" </path/to/body
    printf "\e[3D, done.\n"
}

mapfile <<<"$IN" -td \; -c 1 -C myPubliMail

# Renders the same output:
# Seq:      0: Sending mail to '[email protected]', done.
# Seq:      1: Sending mail to '[email protected]', done.
# Seq:      2: Sending mail to 'Full Name <[email protected]>', done.

Split string based on delimiter in shell

If you can't use bash, or if you want to write something that can be used in many different shells, you often can't use bashisms -- and this includes the arrays we've been using in the solutions above.

However, we don't need to use arrays to loop over "elements" of a string. There is a syntax used in many shells for deleting substrings of a string from the first or last occurrence of a pattern. Note that * is a wildcard that stands for zero or more characters:

(The lack of this approach in any solution posted so far is the main reason I'm writing this answer ;)

${var#*SubStr}  # drops substring from start of string up to first occurrence of `SubStr`
${var##*SubStr} # drops substring from start of string up to last occurrence of `SubStr`
${var%SubStr*}  # drops substring from last occurrence of `SubStr` to end of string
${var%%SubStr*} # drops substring from first occurrence of `SubStr` to end of string

As explained by Score_Under:

# and % delete the shortest possible matching substring from the start and end of the string respectively, and

## and %% delete the longest possible matching substring.

Using the above syntax, we can create an approach where we extract substring "elements" from the string by deleting the substrings up to or after the delimiter.

The codeblock below works well in bash (including Mac OS's bash), dash, ksh, and busybox's ash:

IN="[email protected];[email protected];Full Name <[email protected]>"
while [ "$IN" ] ;do
    # extract the substring from start of string up to delimiter.
    # this is the first "element" of the string.
    iter=${IN%%;*}
    echo "> [$iter]"
    # if there's only one element left, set `IN` to an empty string.
    # this causes us to exit this `while` loop.
    # else, we delete the first "element" of the string from IN, and move onto the next.
    [ "$IN" = "$iter" ] && \
        IN='' || \
        IN="${IN#*;}"
  done
# > [[email protected]]
# > [[email protected]]
# > [Full Name <[email protected]>]

Have fun!

If you really want to list modified files only you can reduce the output of svn st by leading "M" that indicates a file has been modified. I would do this like that:

svn st | grep ^M

One of my windows services is logged on as Local System in windows server 2016, and I can find the user.config under C:\Windows\SysWOW64\config\systemprofile\AppData\Local\{your application name}.

I think the easiest way is searching your application name on C drive and then check where is the user.config

I just did

1.Invalidate caches and restart

2.Rebuilt my project which solved the problem

In C and C++

unsigned = unsigned int (Integer type)
signed   = signed int (Integer type)

An unsigned integer containing n bits can have a value between 0 and (2^n-1) , which is 2^n different values.

An unsigned integer is either positive or zero.

Signed integers are stored in a computer using 2's complement.

TCP has a feature called "TIME_WAIT" that ensures connections are closed cleanly. It requires one end of the connection to stay listening for a while after the socket has been closed.

In a high-performance server, it's important that it's the clients who go into TIME_WAIT, not the server. Clients can afford to have a port open, whereas a busy server can rapidly run out of ports or have too many open FDs.

To achieve this, the server should never close the connection first -- it should always wait for the client to close it.

How about this?

(A=1 OR B=1 OR C=1) 
AND NOT (A=1 AND B=1 AND C=1)

And if A, B and C can have null values you would need the following:

(A=1 OR B=1 OR C=1) 
AND NOT ( (A=1 AND A is not null) AND (B=1 AND B is not null) AND (C=1 AND C is not null) )

This is scalable to larger number of fields and hence more applicable.

Check out the basics of regular expressions in a tutorial. All it requires is two anchors and a repeated character class:

^[a-zA-Z ._-]*$

If you use the case-insensitive modifier, you can shorten this to

^[a-z ._-]*$

Note that the space is significant (it is just a character like any other).

Webservices require unique namespaces so they don't confuse each others schemas and whatever with each other. A URL (domain, subdomain, subsubdomain, etc) is a clever identifier as it's "guaranteed" to be unique, and in most circumstances you've already got one.

The current answers are fine and should work ok, but what's wrong with the more simple, more obvious, and more maintainable:

IF @flag = 1
    UPDATE table_name SET column_A = column_A + @new_value WHERE ID = @ID;
ELSE
    UPDATE table_name SET column_B = column_B + @new_value WHERE ID = @ID;

This is much easier to read albeit this is a very simple query.

Here's a working example courtesy of @snyder: SqlFiddle.

Wrong answer - see EDIT at the end

Let me build on Alex's answer.

To prevent the creation of a data object if it doesn't exists, I would better do:

$.fn.hasData = function(key) {
    var $this = $(this);
    return $.hasData($this) && typeof $this.data(key) !== 'undefined';
};

Then, where $this has no data object created, $.hasData returns false and it will not execute $this.data(key).

EDIT: function $.hasData(element) works only if the data was set using $.data(element, key, value), not element.data(key, value). Due to that, my answer is not correct.

Appart from what is told here, in my case I missed import UIKit:

The cleanest way to manage multiple java versions on Mac is to use Homebrew.

And within Homebrew, use:

• homebrew-cask to install the versions of java
• jenv to manage the installed versions of java

As seen on http://hanxue-it.blogspot.ch/2014/05/installing-java-8-managing-multiple.html , these are the steps to follow.

1. install homebrew
2. install homebrew jenv
3. install homebrew-cask
4. install a specific java version using cask (see "homebrew-cask versions" paragraph below)
5. add this version for jenv to manage it
6. check the version is correctly managed by jenv
7. repeat steps 4 to 6 for each version of java you need

homebrew-cask versions

Add the homebrew/cask-versions tap to homebrew using:

brew tap homebrew/cask-versions

Then you can look at all the versions available:

brew search java

Then you can install the version(s) you like:

brew cask install java7
brew cask install java6

And add them to be managed by jenv as usual.

jenv add <javaVersionPathHere>

I think this is the cleanest & simplest way to go about it.

Another important thing to note, as mentioned in Mac OS X 10.6.7 Java Path Current JDK confusing :

For different types of JDKs or installations, you will have different paths

You can check the paths of the versions installed using /usr/libexec/java_home -V, see How do I check if the Java JDK is installed on Mac?

On Mac OS X Mavericks, I found as following:

1) Built-in JRE default: /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

2) JDKs downloaded from Apple: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/

3) JDKs downloaded from Oracle: /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home

If you are trying to use AngularJs 1.6.6 as of 21/10/2017 the following parameter works as .success and has been depleted. The .then() method takes two arguments: a response and an error callback which will be called with a response object.

 $scope.login = function () {
        $scope.btntext = "Please wait...!";
        $http({
            method: "POST",
            url: '/Home/userlogin', // link UserLogin with HomeController 
            data: $scope.user
         }).then(function (response) {
            console.log("Result value is : " + parseInt(response));
            data = response.data;
            $scope.btntext = 'Login';
            if (data == 1) {
                window.location.href = '/Home/dashboard';
             }
            else {
            alert(data);
        }
        }, function (error) {

        alert("Failed Login");
        });

The above snipit works for a login page.

                    layoutParams = RelativeLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
                            LinearLayout.LayoutParams.WRAP_CONTENT).apply {
                        addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
                        // addRule(RelativeLayout.LEFT_OF, myImageButton.id)
                    }
                }))
            }
        }
        this.addView(parent)
    }
}

Check who the group and owner are of the folder where the script runs. If the group id or user id are wrong, for example, set to root, it will cause sessions to not be saved properly.

-Build
-Generate Signed Apk
-Create new

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

git checkout -b NEW_BRANCH_NAME COMMIT_ID

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

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

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

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

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

Often there are questions about the java settings in vsCode. This is a big question and can involve advanced user knowledge to accmplish. But there is simple way to get the existing java settings from vsCode and copy these setting for use on another PC. This post is using recent versions of vsCode and JDK in mid-December 2020.

There are several screen shots (below) that accompany this post which should provide enough information for the visual learners.

First things first, open vsCode and either open an existing java folder-file or create a new java file in vsCode. Then look at the lower right corner of vsCode (on the blue command bar). The vsCode should be displaying an icon showing the version of the Java Standard Edition ( Java SE ) being used. The version being on this PC today is JavaSE-15. (link 1)

Click on that icon (JAVASE-15) which then opens a new window named "java.configuration.runtimes". There should be two tabs below this name: User and Workspace. Below these tabs is a link named, "Edit in settings.json". Click on that link. (link 2)

Two json files should then open: Default settings and settings.json. This post only focuses on the "settings.json" file. The settings.json file shows various settings used for coding different programming languages (Python, R, and java). Near the bottom of the settings.json file shows the settings this User uses in vsCode for programming java.

These java settings are the settings that can be "backed up" - meaning these settings get copied and pasted to another PC for creating a java programming environment similar to the java programming environment on this PC. (link 3)

I used ganymede for this a few yeas ago... http://www.cleondris.ch/opensource/ssh2/

Install the packages:

sudo apt-get install libaio1 libaio-dev

or

sudo yum install libaio

myfunc is an attribute of MyClass. That's how it's found when you run:

myinstance = MyClass()
myinstance.myfunc()

It looks for an attribute on myinstance named myfunc, doesn't find one, sees that myinstance is an instance of MyClass and looks it up there.

So the complete list of attributes for MyClass is:

>>> dir(MyClass)
['__doc__', '__module__', 'a', 'b', 'myfunc']

(Note that I'm using dir just as a quick and easy way to list the members of the class: it should only be used in an exploratory fashion, not in production code)

If you only want particular attributes, you'll need to filter this list using some criteria, because __doc__, __module__, and myfunc aren't special in any way, they're attributes in exactly the same way that a and b are.

I've never used the inspect module referred to by Matt and Borealid, but from a brief link it looks like it has tests to help you do this, but you'll need to write your own predicate function, since it seems what you want is roughly the attributes that don't pass the isroutine test and don't start and end with two underscores.

Also note: by using class MyClass(): in Python 2.7 you're using the wildly out of date old-style classes. Unless you're doing so deliberately for compatibility with extremely old libraries, you should be instead defining your class as class MyClass(object):. In Python 3 there are no "old-style" classes, and this behaviour is the default. However, using newstyle classes will get you a lot more automatically defined attributes:

>>> class MyClass(object):
        a = "12"
        b = "34"
        def myfunc(self):
            return self.a
>>> dir(MyClass)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'a', 'b', 'myfunc']

Easiest way for me was to create an extra column with an if statement to essentially use as a copy past clipboard.

=IF(desired cell = 0, "", desired cell)

That should return a corrected column which then you can copy and paste back over the original column AS TEXT--if you just copy paste a circular reference occurs and all the data is "erased" from both columns. Don't fret if you didn't read this carefully Ctrl+Z is your best friend...

I typed this in my URL bar:

javascript:{ var col = 'screwdriver'; var x = '<option value="' + col + '"' + ((col == 'screwdriver') ? ' selected' : '') + '>Very roomy</option>'; alert(x); }

I had same problem even after changing the password, it wasn't getting reflected in SQLDEVELOPER.

Atlast following solved my problem :

1. Open Command Propmt
2. Type sqlplus
3. login as sysdba
4. Run following command : alter user USERNAME identified by NEW_PASSWORD;

I'm using nGram, too. I use standard tokenizer and nGram just as a filter. Here is my setup:

{
  "index": {
    "index": "my_idx",
    "type": "my_type",
    "analysis": {
      "index_analyzer": {
        "my_index_analyzer": {
          "type": "custom",
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "mynGram"
          ]
        }
      },
      "search_analyzer": {
        "my_search_analyzer": {
          "type": "custom",
          "tokenizer": "standard",
          "filter": [
            "standard",
            "lowercase",
            "mynGram"
          ]
        }
      },
      "filter": {
        "mynGram": {
          "type": "nGram",
          "min_gram": 2,
          "max_gram": 50
        }
      }
    }
  }
}

Let's you find word parts up to 50 letters. Adjust the max_gram as you need. In german words can get really big, so I set it to a high value.

with paging you need to do some calculation

int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

Note: This answer should probably not be used in production code. It's a hack and you should know about the implications.

There is the uvrun module (updated for newer Nodejs versions here) where you can execute a single loop round of the libuv main event loop (which is the Nodejs main loop).

Your code would look like this:

function(query) {
  var r;
  myApi.exec('SomeCommand', function(response) {
    r = response;
  });
  var uvrun = require("uvrun");
  while (!r)
    uvrun.runOnce();
  return r;
}

(You might alternative use uvrun.runNoWait(). That could avoid some problems with blocking, but takes 100% CPU.)

Note that this approach kind of invalidates the whole purpose of Nodejs, i.e. to have everything async and non-blocking. Also, it could increase your callstack depth a lot, so you might end up with stack overflows. If you run such function recursively, you definitely will run into troubles.

See the other answers about how to redesign your code to do it "right".

This solution here is probably only useful when you do testing and esp. want to have synced and serial code.

A basic for statement includes

• 0..n initialization statements (ForInit)
• 0..1 expression statements that evaluate to boolean or Boolean (ForStatement) and
• 0..n update statements (ForUpdate)

If you need multiple conditions to build your ForStatement, then use the standard logic operators (&&, ||, |, ...) but - I suggest to use a private method if it gets to complicated:

for (int i = 0, j = 0; isMatrixElement(i,j,myArray); i++, j++) { 
   // ...
}

and

private boolean isMatrixElement(i,j,myArray) {
  return (i < myArray.length) && (j < myArray[i].length);  //  stupid dummy code!
}

i had this problem using bitcoinJ library (org.bitcoinj:bitcoinj-core:0.14.7) added to build.gradle(in module app) a packaging options inside the android scope. it helped me.

android {
...
    packagingOptions {
        exclude 'lib/x86_64/darwin/libscrypt.dylib'
        exclude 'lib/x86_64/freebsd/libscrypt.so'
        exclude 'lib/x86_64/linux/libscrypt.so'
    }
}

There are 3 different libraries that wraps libmagic.

2 of them are available on pypi (so pip install will work):

• filemagic
• python-magic

And another, similar to python-magic is available directly in the latest libmagic sources, and it is the one you probably have in your linux distribution.

In Debian the package python-magic is about this one and it is used as toivotuo said and it is not obsoleted as Simon Zimmermann said (IMHO).

It seems to me another take (by the original author of libmagic).

Too bad is not available directly on pypi.

Client need to notify that it finished sending, using socket.shutdown (not socket.close which close both reading/writing part of the socket):

...
print "Done Sending"
s.shutdown(socket.SHUT_WR)
print s.recv(1024)
s.close()

UPDATE

Client sends Hello server! to the server; which is written to the file in the server side.

s.send("Hello server!")

Remove above line to avoid it.

The same error appears if you do not use the correct (numeric) format of your data in your data.frame column using mean() function. Therefore, check your data using str(data.frame&column) function to see what data type you have, and convert it to numeric format if necessary. For example, if your data is Character convert it with as.numeric(data.frame$column), or as a factor with as.numeric(as.character(data.frame$column)). The mean function does not work with types other than numeric.

Check, if you are not accidentally requesting HTTPS protocol instead of HTTP.

I have overlooked that I was requesting https://localhost:... instead of http://localhost:... and it resulted to this weird message..

If you really want them to have ALL rights:

use YourDatabase
go
exec sp_addrolemember 'db_owner', 'UserName'
go

You are not adding the object to the session, instead you are adding it to the request.
What you need is:

HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);

In Servlets you have 4 scopes where you can store data.

1. Application
2. Session
3. Request
4. Page

Make sure you understand these. For more look here

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }

I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

// Sample usage in CSHTML

 @Html.ActionImage("Edit",
       "EditController"
        new { id = MyId },
       "~/Content/Images/Image.bmp",
       new { width=108, height=129, alt="Edit" })

And the extension class for the code above:

using System.Collections.Generic;
using System.Reflection;
using System.Web.Mvc;

namespace MVC.Extensions
{
    public static class MvcHtmlStringExt
    {
        // Extension method
        public static MvcHtmlString ActionImage(
          this HtmlHelper html,
          string action,
          string controllerName,
          object routeValues,
          string imagePath,
          object htmlAttributes)
        {
            //https://stackoverflow.com/questions/4896439/action-image-mvc3-razor
            var url = new UrlHelper(html.ViewContext.RequestContext);

            // build the <img> tag
            var imgBuilder = new TagBuilder("img");
            imgBuilder.MergeAttribute("src", url.Content(imagePath));

            var dictAttributes = htmlAttributes.ToDictionary();

            if (dictAttributes != null)
            {
                foreach (var attribute in dictAttributes)
                {
                    imgBuilder.MergeAttribute(attribute.Key, attribute.Value.ToString(), true);
                }
            }                        

            string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

            // build the <a> tag
            var anchorBuilder = new TagBuilder("a");
            anchorBuilder.MergeAttribute("href", url.Action(action, controllerName, routeValues));
            anchorBuilder.InnerHtml = imgHtml; // include the <img> tag inside            
            string anchorHtml = anchorBuilder.ToString(TagRenderMode.Normal);

            return MvcHtmlString.Create(anchorHtml);
        }

        public static IDictionary<string, object> ToDictionary(this object data)
        {
            //https://stackoverflow.com/questions/6038255/asp-net-mvc-helpers-merging-two-object-htmlattributes-together

            if (data == null) return null; // Or throw an ArgumentNullException if you want

            BindingFlags publicAttributes = BindingFlags.Public | BindingFlags.Instance;
            Dictionary<string, object> dictionary = new Dictionary<string, object>();

            foreach (PropertyInfo property in
                     data.GetType().GetProperties(publicAttributes))
            {
                if (property.CanRead)
                {

PuTTYgen for Ubuntu/Linux and PEM to PPK

sudo apt install putty-tools

If you use Kotlin, you can add an extension method to Image in the same manner Sri Harsha Chilakapati suggests.

fun Image.toBufferedImage(): BufferedImage {
    if (this is BufferedImage) {
        return this
    }
    val bufferedImage = BufferedImage(this.getWidth(null), this.getHeight(null), BufferedImage.TYPE_INT_ARGB)

    val graphics2D = bufferedImage.createGraphics()
    graphics2D.drawImage(this, 0, 0, null)
    graphics2D.dispose()

    return bufferedImage
}

And use it like this:

myImage.toBufferedImage()

On controller.

$your_variable = '';
$your_variable .= '<p>Hello world</p>';

return view('viewname')->with('your_variable', $your_variable)

If you do not want your data to be escaped, you may use the following syntax:

{!! $your_variable !!}

Output

Hello world

To add to the comparison: (burst)read/write-performance on EFS depends on gathered credits. Gathering of credits depends on the amount of data you store on it. More date -> more credits. That means that when you only need a few GB of storage which is read or written often you will run out of credits very soon and througphput drops to about 50kb/s. The only way to fix this (in my case) was to add large dummy files to increase the rate credits are earned. However more storage -> more cost.

It is nice for a Python module to have a docstring, explaining what the module does, what it provides, examples of how to use the classes. This is different from the comments that you often see at the beginning of a file giving the copyright and license information, which IMO should not go in the docstring (some even argue that they should disappear altogether, see e.g. Get Rid of Source Code Templates)

With Pylint 2.4 and above, you can differentiate between the various missing-docstring by using the three following sub-messages:

• C0114 (missing-module-docstring)
• C0115 (missing-class-docstring)
• C0116 (missing-function-docstring)

So the following .pylintrc file should work:

[MASTER]
disable=
    C0114, # missing-module-docstring

For previous versions of Pylint, it does not have a separate code for the various place where docstrings can occur, so all you can do is disable C0111. The problem is that if you disable this at module scope, then it will be disabled everywhere in the module (i.e., you won't get any C line for missing function / class / method docstring. Which arguably is not nice.

So I suggest adding that small missing docstring, saying something like:

"""
high level support for doing this and that.
"""

Soon enough, you'll be finding useful things to put in there, such as providing examples of how to use the various classes / functions of the module which do not necessarily belong to the individual docstrings of the classes / functions (such as how these interact, or something like a quick start guide).

First we'll consider loops where the number of iterations of the inner loop is independent of the value of the outer loop's index. For example:

 for (i = 0; i < N; i++) {
     for (j = 0; j < M; j++) {
         sequence of statements
      }
  }

The outer loop executes N times. Every time the outer loop executes, the inner loop executes M times. As a result, the statements in the inner loop execute a total of N * M times. Thus, the total complexity for the two loops is O(N2).

Use:

return [n]

From help return

return: return [n]

Return from a shell function.

Causes a function or sourced script to exit with the return value
specified by N.  If N is omitted, the return status is that of the
last command executed within the function or script.

Exit Status:
Returns N, or failure if the shell is not executing a function or script.

I wrote an HTML5 video player around broadway h264 codec (emscripten) that can play live (no delay) h264 video on all browsers (desktop, iOS, ...).

Video stream is sent through websocket to the client, decoded frame per frame and displayed in a canva (using webgl for acceleration)

Check out https://github.com/131/h264-live-player on github.

A dict (really, a defaultdict) gives you a pretty easy way to do this trick:

from collections import defaultdict
bool_mapping = defaultdict(bool) # Will give you False for non-found values
for val in ['True', 'yes', ...]:
    bool_mapping[val] = True

print(bool_mapping['True']) # True
print(bool_mapping['kitten']) # False

It's really easy to tailor this method to the exact conversion behavior you want -- you can fill it with allowed Truthy and Falsy values and let it raise an exception (or return None) when a value isn't found, or default to True, or default to False, or whatever you want.

(I tried previous answers but they lacks in some points. For example if you don't do a return; after finishing activity, remaining activity code runs. Also you need to edit onCreate with return. If you doesn't run super.onCreate() you will get a runtime error)

Say you have MainActivity and ChildActivity.

Inside ChildActivity add this:

Intent intent = new Intent(ChildActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);
return true;

Inside MainActivity's onCreate add this:

@Override
public void onCreate(Bundle savedInstanceState) {

    mContext = getApplicationContext();

    super.onCreate(savedInstanceState);

    if (getIntent().getBooleanExtra("EXIT", false)) {
        finish();
        return;
    }
    // your current codes
    // your current codes
}

When you don't have a PC on hand, you could use Eruda, which is devtools for mobile browsers https://github.com/liriliri/eruda
It is provided as embeddable javascript and also a bookmarklet (pasting bookmarklet in chrome removes the javascript: prefix, so you have to type it yourself)

You can use this code:

android:textSize="32dp"

it solves your problem but you must know that you should respect user decisions. by this, changing text size from device settings will not change this value. so that's why you need to use sp instead of dp. So my suggestion is to review your app with different system font sizes(small,normal,big,...)

1) Ensure you're in branch where you need a copy of the file. for eg: i want sub branch file in master so you need to checkout or should be in master git checkout master

2) Now checkout specific file alone you want from sub branch into master,

git checkout sub_branch file_path/my_file.ext

here sub_branch means where you have that file followed by filename you need to copy.

I have tested almost all methods given here in this page for my Angular app. Only I found solution via   that inserts spaces i.e.

Angular Material

add   in the placeholder, like

<input matInput type="text" placeholder="&nbsp;&nbsp;Email">

Non Angular Material

Add padding to your input field, like below. Click Run Code Snippet to see demo

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container m-3 d-flex flex-column align-items-center justify-content-around" style="height:100px;">
<input type="text" class="pl-0" placeholder="Email with no Padding" style="width:240px;">
<input type="text" class="pl-3" placeholder="Email with 1 rem padding" style="width:240px;">
</div>

First treat the number like a string

number = 9876543210
number = str(number)

Then to get the first digit:

number[0]

The fourth digit:

number[3]

EDIT:

This will return the digit as a character, not as a number. To convert it back use:

int(number[0])

Remove warnings.filterwarnings and add:

numpy.seterr(all='raise')

python3.6 -m pip install opencv-python

will install cv2 in linux in branch python3.6

From http://www.codeave.com/javascript/code.asp?u_log=7004:

var input = document.getElementById('myTextInput');_x000D_
input.focus();_x000D_
input.select();

<input id="myTextInput" value="Hello world!" />

The following definition might be more efficient than the first solution proposed

def new_list_from_intervals(original_list, *intervals):
    n = sum(j - i for i, j in intervals)
    new_list = [None] * n
    index = 0
    for i, j in intervals :
        for k in range(i, j) :
            new_list[index] = original_list[k]
            index += 1

    return new_list

then you can use it like below

new_list = new_list_from_intervals(original_list, (0,2), (4,5), (6, len(original_list)))

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

For Any *.Exe file written in any language .You can view the source code with hiew (otherwise Hackers view). You can download it at www.hiew.ru. It will be the demo version but still can view the code.

After this follow these steps:

1. Press alt+f2 to navigate to the file.

2. Press enter to see its assembly / c++ code.

Can you provide some more details like which linux you are using? Are you loged in as root? On linux you have to run export CLASSPATH = %path%;LOG4J_HOME/og4j-1.2.16.jar If you want it permanent then you can add above lines in ~/.bashrc file.

To improve upon the answer given by derobert,

You can determine what your OS connection limit is by catting nf_conntrack_max.

For example: cat /proc/sys/net/netfilter/nf_conntrack_max

You can use the following script to count the number of tcp connections to a given range of tcp ports. By default 1-65535.

This will confirm whether or not you are maxing out your OS connection limit.

Here's the script.

#!/bin/bash
OS=$(uname)

case "$OS" in
    'SunOS')
            AWK=/usr/bin/nawk
            ;;
    'Linux')
            AWK=/bin/awk
            ;;
    'AIX')
            AWK=/usr/bin/awk
            ;;
esac

netstat -an | $AWK -v start=1 -v end=65535 ' $NF ~ /TIME_WAIT|ESTABLISHED/ && $4 !~ /127\.0\.0\.1/ {
    if ($1 ~ /\./)
            {sip=$1}
    else {sip=$4}

    if ( sip ~ /:/ )
            {d=2}
    else {d=5}

    split( sip, a, /:|\./ )

    if ( a[d] >= start && a[d] <= end ) {
            ++connections;
            }
    }
    END {print connections}'

That's usually because you don't have a file called vertex.cpp available to make. Check that:

• that file exists.
• you're in the right directory when you make.

Other than that, I've not much else to suggest. Perhaps you could give us a directory listing of that directory.

If you copy something from disk A to disk B in explorer, Windows employs DMA. That means for most of the copy process, the CPU will basically do nothing other than telling the disk controller where to put, and get data from, eliminating a whole step in the chain, and one that is not at all optimized for moving large amounts of data - and I mean hardware.

What you do involves the CPU a lot. I want to point you to the "Some calculations to fill a[]" part. Which I think is essential. You generate a[], then you copy from a[] to an output buffer (thats what fstream::write does), then you generate again, etc.

What to do? Multithreading! (I hope you have a multi-core processor)

• fork.
• Use one thread to generate a[] data
• Use the other to write data from a[] to disk
• You will need two arrays a1[] and a2[] and switch between them
• You will need some sort of synchronization between your threads (semaphores, message queue, etc.)
• Use lower level, unbuffered, functions, like the the WriteFile function mentioned by Mehrdad

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

Try this: currentLoad = ConvertToLongInteger(oXLSheet2.Cells(4, 6).Value) with this function:

Function ConvertToLongInteger(ByVal stValue As String) As Long
 On Error GoTo ConversionFailureHandler
 ConvertToLongInteger = CLng(stValue)  'TRY to convert to an Integer value
 Exit Function           'If we reach this point, then we succeeded so exit

ConversionFailureHandler:
 'IF we've reached this point, then we did not succeed in conversion
 'If the error is type-mismatch, clear the error and return numeric 0 from the function
 'Otherwise, disable the error handler, and re-run the code to allow the system to 
 'display the error
 If Err.Number = 13 Then 'error # 13 is Type mismatch
      Err.Clear
      ConvertToLongInteger = 0
      Exit Function
 Else
      On Error GoTo 0
      Resume
 End If
End Function

I chose Long (Integer) instead of simply Integer because the min/max size of an Integer in VBA is crummy (min: -32768, max:+32767). It's common to have an integer outside of that range in spreadsheet operations.

The above code can be modified to handle conversion from string to-Integers, to-Currency (using CCur() ), to-Decimal (using CDec() ), to-Double (using CDbl() ), etc. Just replace the conversion function itself (CLng). Change the function return type, and rename all occurrences of the function variable to make everything consistent.

check the images first with php if it is small then the standerd size for logo provide it any other css class and dont change its size

i think you have to take up scripting in between

In a nutshell what it does is refer to the id of the input, that's all:

<label for="the-id-of-the-input">Input here:</label>
<input type="text" name="the-name-of-input" id="the-id-of-the-input">

For small applications it is fine to use Timer and TimerTask as Rohit mentioned but in web applications I would use Quartz Scheduler to schedule jobs and to perform such periodic jobs.

See tutorials for Quartz scheduling.

A static method belongs to the class itself and a non-static (aka instance) method belongs to each object that is generated from that class. If your method does something that doesn't depend on the individual characteristics of its class, make it static (it will make the program's footprint smaller). Otherwise, it should be non-static.

Example:

class Foo {
    int i;

    public Foo(int i) { 
       this.i = i;
    }

    public static String method1() {
       return "An example string that doesn't depend on i (an instance variable)";
    }

    public int method2() {
       return this.i + 1; // Depends on i
    }
}

You can call static methods like this: Foo.method1(). If you try that with method2, it will fail. But this will work: Foo bar = new Foo(1); bar.method2();

In Visual Studio, Right Click your project -> On the left pane click the Build tab,

under Platform Target select x86 (or more generally the architecture to match with the library you are linking to)

I hope this helps someone! :)

you can convert it into date format by-

new_date<- as.Date(old_date, "%m/%d/%Y")} 

from new_date, you can get the month by strftime()

month<- strftime(new_date, "%m")

old_date<- "01/01/1979"
new_date<- as.Date(old_date, "%m/%d/%Y")
new_date
#[1] "1979-01-01"
month<- strftime(new_date,"%m")
month
#[1] "01"
year<- strftime(new_date, "%Y")
year
#[1] "1979"

Use the following code:

$('input[name^=CheckBoxInput]').val();

Using custom Structural Directive with index:

According Angular documentation:

createEmbeddedView Instantiates an embedded view and inserts it into this container.

abstract createEmbeddedView(templateRef: TemplateRef, context?: C, index?: number): EmbeddedViewRef.

Param          Type           Description
templateRef    TemplateRef    the HTML template that defines the view.
context        C              optional. Default is undefined.
index          number         the 0-based index at which to insert the new view into this container. If not specified, appends the new view as the last entry.

When angular creates template by calling createEmbeddedView it can also pass context that will be used inside ng-template.

Using context optional parameter, you may use it in the component, extracting it within the template just as you would with the *ngFor.

app.component.html:

<p *for="number; let i=index; let c=length; let f=first; let l=last; let e=even; let o=odd">
  item : {{i}} / {{c}}
  <b>
    {{f ? "First,": ""}}
    {{l? "Last,": ""}}
    {{e? "Even." : ""}}
    {{o? "Odd." : ""}}
  </b>
</p>

for.directive.ts:

import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core';

class Context {
  constructor(public index: number, public length: number) { }
  get even(): boolean { return this.index % 2 === 0; }
  get odd(): boolean { return this.index % 2 === 1; }
  get first(): boolean { return this.index === 0; }
  get last(): boolean { return this.index === this.length - 1; }
}

@Directive({
  selector: '[for]'
})
export class ForDirective {
  constructor(private templateRef: TemplateRef<any>, private viewContainer: ViewContainerRef) { }

  @Input('for') set loop(num: number) {
    for (var i = 0; i < num; i++)
      this.viewContainer.createEmbeddedView(this.templateRef, new Context(i, num));
  }
}

Profiling with XDebug

An extension to PHP called Xdebug is available to assist in profiling PHP applications, as well as runtime debugging. When running the profiler, the output is written to a file in a binary format called "cachegrind". Applications are available on each platform to analyze these files. No application code changes are necessary to perform this profiling.

To enable profiling, install the extension and adjust php.ini settings. Some Linux distributions come with standard packages (e.g. Ubuntu's php-xdebug package). In our example we will run the profile optionally based on a request parameter. This allows us to keep settings static and turn on the profiler only as needed.

# php.ini settings
# Set to 1 to turn it on for every request
xdebug.profiler_enable = 0
# Let's use a GET/POST parameter to turn on the profiler
xdebug.profiler_enable_trigger = 1
# The GET/POST value we will pass; empty for any value
xdebug.profiler_enable_trigger_value = ""
# Output cachegrind files to /tmp so our system cleans them up later
xdebug.profiler_output_dir = "/tmp"
xdebug.profiler_output_name = "cachegrind.out.%p"

Next use a web client to make a request to your application's URL you wish to profile, e.g.

http://example.com/article/1?XDEBUG_PROFILE=1

As the page processes it will write to a file with a name similar to

/tmp/cachegrind.out.12345

By default the number in the filename is the process id which wrote it. This is configurable with the xdebug.profiler_output_name setting.

Note that it will write one file for each PHP request / process that is executed. So, for example, if you wish to analyze a form post, one profile will be written for the GET request to display the HTML form. The XDEBUG_PROFILE parameter will need to be passed into the subsequent POST request to analyze the second request which processes the form. Therefore when profiling it is sometimes easier to run curl to POST a form directly.

Analyzing the Output

Once written the profile cache can be read by an application such as KCachegrind or Webgrind. PHPStorm, a popular PHP IDE, can also display this profiling data.

KCachegrind, for example, will display information including:

• Functions executed
• Call time, both itself and inclusive of subsequent function calls
• Number of times each function is called
• Call graphs
• Links to source code

What to Look For

Obviously performance tuning is very specific to each application's use cases. In general it's good to look for:

• Repeated calls to the same function you wouldn't expect to see. For functions that process and query data these could be prime opportunities for your application to cache.
• Slow-running functions. Where is the application spending most of its time? the best payoff in performance tuning is focusing on those parts of the application which consume the most time.

Note: Xdebug, and in particular its profiling features, are very resource intensive and slow down PHP execution. It is recommended to not run these in a production server environment.

Agile is the practice and Scrum is the process to following this practice same as eXtreme Programming (XP) and Kanban are the alternative process to following Agile development practice.

you could deserialize your json string into a dictionary and then add new properties then serialize it.

 var jsonString = @"{}";

        var jsonDoc = JsonSerializer.Deserialize<Dictionary<string, object>>(jsonString);

        jsonDoc.Add("Name", "Khurshid Ali");

        Console.WriteLine(JsonSerializer.Serialize(jsonDoc));

As posted I followed moeamaya's answer but needed to modify it just a bit to see my work in the Sites directory.

I have used this simple code, and it works!

for (int i = 0; i < N * N; i++)
     {
        Thread.Sleep(50);
        progressBar1.BeginInvoke(new Action(() => progressBar1.Value = i));
        progressBar1.CreateGraphics().DrawString(i.ToString() + "%", new Font("Arial",
        (float)10.25, FontStyle.Bold),
        Brushes.Red, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
     }

It just has one simple problem and this is it: when progress bar start to rising, percentage some times hide, and then appear again. I did't write it myself.I found it here: text on progressbar in c#

I used this code, and it does work.

While Niemeyer's answer is a more correct answer to the question, you could also do the following:

<div>
  <input data-bind="value: VMA.name" />
</div>

<div>
  <input data-bind="value: VMB.name" />
</div>

<script type="text/javascript">
  var viewModels = {
     VMA: {name: ko.observable("Bob")},
     VMB: {name: ko.observable("Ted")}
  };

  ko.applyBindings(viewModels);
</script>

This means you don't have to specify the DOM element, and you can even bind multiple models to the same element, like this:

<div>
  <input data-bind="value: VMA.name() + ' and ' + VMB.name()" />
</div>

You are calling the constructor of its base class, demo.

In my case, I'm using j-hipster and I had to do ./mvnw clean to overcome this warning.

In the ideal world you would set the text style attribute in you layout XML definition like that:

<TextView
    android:id="@+id/TextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textStyle="bold"/>

There is a simple way to achieve the same result dynamically in your code by using setTypeface method. You need to pass and object of Typeface class, which will describe the font style for that TextView. So to achieve the same result as with the XML definition above you can do the following:

TextView Tv = (TextView) findViewById(R.id.TextView);
Typeface boldTypeface = Typeface.defaultFromStyle(Typeface.BOLD);
Tv.setTypeface(boldTypeface);

The first line will create the object form predefined style (in this case Typeface.BOLD, but there are many more predefined). Once we have an instance of typeface we can set it on the TextView. And that's it our content will be displayed on the style we defined.

I hope it helps you a lot.For better info you can visit

           // Set ListView divider color
            lv.setDivider(new ColorDrawable(Color.parseColor("#FF4A4D93")));

            // set ListView divider height
            lv.setDividerHeight(2);

using xml

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"

    android:dividerHeight="4px"/>

Following on Ivan Krechetov's answer, here is a function that does mail merge (actually just simple text replace) for docx and odt, without the need for an extra library.

function mailMerge($templateFile, $newFile, $row)
{
  if (!copy($templateFile, $newFile))  // make a duplicate so we dont overwrite the template
    return false; // could not duplicate template
  $zip = new ZipArchive();
  if ($zip->open($newFile, ZIPARCHIVE::CHECKCONS) !== TRUE)
    return false; // probably not a docx file
  $file = substr($templateFile, -4) == '.odt' ? 'content.xml' : 'word/document.xml';
  $data = $zip->getFromName($file);
  foreach ($row as $key => $value)
    $data = str_replace($key, $value, $data);
  $zip->deleteName($file);
  $zip->addFromString($file, $data);
  $zip->close();
  return true;
}

This will replace [Person Name] with Mina and [Person Last Name] with Mooo:

$replacements = array('[Person Name]' => 'Mina', '[Person Last Name]' => 'Mooo');
$newFile = tempnam_sfx(sys_get_temp_dir(), '.dat');
$templateName = 'personinfo.docx';
if (mailMerge($templateName, $newFile, $replacements))
{
  header('Content-type: application/msword');
  header('Content-Disposition: attachment; filename=' . $templateName);
  header('Accept-Ranges: bytes');
  header('Content-Length: '. filesize($file));
  readfile($newFile);
  unlink($newFile);
}

Beware that this function can corrupt the document if the string to replace is too general. Try to use verbose replacement strings like [Person Name].

NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft]; [[UIDevice currentDevice] setValue:value forKey:@"orientation"];

does work but you have to return shouldAutorotate with YES in your view controller

- (BOOL)shouldAutorotate
{
    return self.shouldAutoRotate;
}

But if you do that, your VC will autorotate if the user rotates the device... so I changed it to:

@property (nonatomic, assign) BOOL shouldAutoRotate;

- (BOOL)shouldAutorotate
{
    return self.shouldAutoRotate;
}

and I call

- (void)swithInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    self.rootVC.shouldAutoRotate = YES;

    NSNumber *value = [NSNumber numberWithInt: orientation];
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}

to force a new orientation with a button-click. To set back shouldAutoRotate to NO, I added to my rootVC

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    self.shouldAutoRotate = NO;
}

PS: This workaround does work in all simulators too.

This will get you the most expensive car for the user:

SELECT users.userName, MAX(cars.carPrice)
FROM users
LEFT JOIN cars ON cars.belongsToUser=users.id
WHERE users.id=4
GROUP BY users.userName

However, this statement makes me think that you want all of the cars prices sorted, descending:

So question: How do I set the LEFT JOIN table to be ordered by carPrice, DESC ?

So you could try this:

SELECT users.userName, cars.carPrice
FROM users
LEFT JOIN cars ON cars.belongsToUser=users.id
WHERE users.id=4
GROUP BY users.userName
ORDER BY users.userName ASC, cars.carPrice DESC

A recursive CTE solution was suggested, but no code was provided. The code below is an example of a recursive CTE. Note that although the results match the question, the data doesn't quite match the given description, as I assume that you really want to be doing this on groups of rows, not all rows in the table. Changing it to match all rows in the table is left as an exercise for the reader.

;WITH basetable AS (
    SELECT
        id,
        CAST(name AS VARCHAR(MAX)) name, 
        ROW_NUMBER() OVER (Partition BY id ORDER BY seq) rw, 
        COUNT(*) OVER (Partition BY id) recs 
    FROM (VALUES
        (1, 'Johnny', 1),
        (1, 'M', 2), 
        (2, 'Bill', 1),
        (2, 'S.', 4),
        (2, 'Preston', 5),
        (2, 'Esq.', 6),
        (3, 'Ted', 1),
        (3, 'Theodore', 2),
        (3, 'Logan', 3),
        (4, 'Peter', 1),
        (4, 'Paul', 2),
        (4, 'Mary', 3)
    ) g (id, name, seq)
),
rCTE AS (
    SELECT recs, id, name, rw
    FROM basetable
    WHERE rw = 1

    UNION ALL

    SELECT b.recs, r.ID, r.name +', '+ b.name name, r.rw + 1
    FROM basetable b
    INNER JOIN rCTE r ON b.id = r.id AND b.rw = r.rw + 1
)
SELECT name
FROM rCTE
WHERE recs = rw AND ID=4

Note: This answer was given when the question didn't specify Android as the context. For an answer specific to the Android UI thread look here.

It looks like the Mac OS API lets the current thread continue, and schedules the task to run asynchronously. In the Java, the equivalent function is provided by the java.util.concurrent package. I'm not sure what limitations Android might impose.

            contentType: "application/json; charset=utf-8",
            traditional: true,
            success: function (data) {
                ...
            }
        });

and in action

public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...

you can bind your array like this

var SendInfo = [];

$(this).parents('table').find('input:checked').each(function () {
    var domain = {
        name: $("#id-manuf-name").val(),
        address: $("#id-manuf-address").val(),
        phone: $("#id-manuf-phone").val(),
    }

    SendInfo.push(domain);
});

hope this can help you.

you can use lst.pop() or del lst[-1]

pop() removes and returns the item, in case you don't want have a return use del

This isn't a clear answer as to why, but we had this problem, here's our circumstances and what solved it:

Dev 1:

Solution contains Project A referencing a NuGet Package, and an MVC project referencing Project A. Enabled NuGet Package Restore, then updated the NuGet package. Got a runtime error complaining the NuGet lib can't be found - but the error is it looking for the older, non-updated version. Solution (and this is ridiculous): Set a breakpoint on the first line of code in the MVC project that calls Project A. Step in with F11. Solved - never had a problem again.

Dev 2:

Same solution and projects, but the magic set breakpoint and step in solution doesn't work. Looked everywhere for version redirects or other bad references to this Nuget package, removed package and reinstalled it, wiped bin, obj, Asp.Net Temp, nothing solved it. Finally, renamed Project A, ran the MVC project - fixed. Renamed it back to its original name, it stayed fixed.

I don't have any explanation for why that worked, but it did get us out of a serious lurch.

Simply add this to your pom.xml:

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-simple</artifactId>
  <version>1.7.21</version>
</dependency>

In my case, resetting ADB didn't make a difference. I also needed to delete my existing virtual devices, which were pretty old, and create new ones.

Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

Source

Why?

It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.

See the following information in MSDN about the GAC changes in 4.0.

For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.

As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

Could there be any problem if i replace Method-1 by Method-2?

No, just use map[key] = value. The two options are equivalent.

Regarding Dictionary<> vs. Hashtable: When you start Reflector, you see that the indexer setters of both classes call this.Insert(key, value, add: false); and the add parameter is responsible for throwing an exception, when inserting a duplicate key. So the behavior is the same for both classes.

Capturing lambdas cannot be converted to function pointers, as this answer pointed out.

However, it is often quite a pain to supply a function pointer to an API that only accepts one. The most often cited method to do so is to provide a function and call a static object with it.

static Callable callable;
static bool wrapper()
{
    return callable();
}

This is tedious. We take this idea further and automate the process of creating wrapper and make life much easier.

#include<type_traits>
#include<utility>

template<typename Callable>
union storage
{
    storage() {}
    std::decay_t<Callable> callable;
};

template<int, typename Callable, typename Ret, typename... Args>
auto fnptr_(Callable&& c, Ret (*)(Args...))
{
    static bool used = false;
    static storage<Callable> s;
    using type = decltype(s.callable);

    if(used)
        s.callable.~type();
    new (&s.callable) type(std::forward<Callable>(c));
    used = true;

    return [](Args... args) -> Ret {
        return Ret(s.callable(std::forward<Args>(args)...));
    };
}

template<typename Fn, int N = 0, typename Callable>
Fn* fnptr(Callable&& c)
{
    return fnptr_<N>(std::forward<Callable>(c), (Fn*)nullptr);
}

And use it as

void foo(void (*fn)())
{
    fn();   
}

int main()
{
    int i = 42;
    auto fn = fnptr<void()>([i]{std::cout << i;});
    foo(fn);  // compiles!
}

Live

This is essentially declaring an anonymous function at each occurrence of fnptr.

Note that invocations of fnptr overwrite the previously written callable given callables of the same type. We remedy this, to a certain degree, with the int parameter N.

std::function<void()> func1, func2;
auto fn1 = fnptr<void(), 1>(func1);
auto fn2 = fnptr<void(), 2>(func2);  // different function

When your network team does ssl-inspection by rewriting certificates, then using a http url instead of a https one, combined with setting this var worked for me.

git config --global http.proxy http://proxy:8081

class Test extends Thread
{
    public void run(){  
        try{  
            Thread.sleep(10000);  
        }catch(InterruptedException e){  
            System.out.println("test1");
            throw new RuntimeException("Thread interrupted..."+e);  
        }  

    }  

    public static void main(String args[]){  
        Test t1=new Test1();  
        t1.start();  
        try{  
            t1.interrupt();  
        }catch(Exception e){
            System.out.println("test2");
            System.out.println("Exception handled "+e);
        }  

    }  
}

Its output doesn't contain test2 , so its not handling runtime exception. @jon skeet, @Jan Zyka

The correct answer:

<form role="search" method="get" action="" target="_blank"></form>

Supported in all major browsers :)

You compile your PHP using --with-curl.

I have got the same problem on Xamarin.Android - VS (2017)

The Solution that worked for me:

SOLUTION

In your XML file add:

 xmlns:card_view="http://schemas.android.com/apk/res-auto"

and in your android.support.v7.widget.CardView element add this propriety:

card_view:cardBackgroundColor="#ffb4b4"

(i.e.)

<android.support.v7.widget.CardView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_margin="12dp"
    card_view:cardCornerRadius="4dp"
    card_view:cardElevation="1dp"
    card_view:cardPreventCornerOverlap="false"
    card_view:cardBackgroundColor="#ffb4b4" />

You can also add cardElevation and cardElevation.

If you want to edit the cardview programmatically you just need to use this code: For (C#)

    cvBianca = FindViewById<Android.Support.V7.Widget.CardView>(Resource.Id.cv_bianca);
    cvBianca.Elevation = 14;
    cvBianca.Radius = 14;
    cvBianca.PreventCornerOverlap = true;
    cvBianca.SetCardBackgroundColor(Color.Red);

And now you can change background color programmatically without lost border, corner radius and elevation.

I needed a really light weight one, Its not 100%, but it gets close enough for some usecases.

float3 Hue(float h, float s, float l)
{
    float r = max(cos(h * 2 * UNITY_PI) * 0.5 + 0.5, 0);
    float g = max(cos((h + 0.666666) * 2 * UNITY_PI) * 0.5 + 0.5, 0);
    float b = max(cos((h + 0.333333) * 2 * UNITY_PI) * 0.5 + 0.5, 0);
    float gray = 0.2989 * r + 0.5870 * g + 0.1140 * b;
    return lerp(gray, float3(r, g, b), s) * smoothstep(0, 0.5, l) + 1 * smoothstep(0.5, 1, l);
}

In case you don't want to mix up with default change event you can provide your custom event

$('input.test').on('value_changed', function(e){
    console.log('value changed to '+$(this).val());
});

to trigger the event on value set, you can do

$('input.test').val('I am a new value').trigger('value_changed');

Your local branch doensn't know about the remote branch. If you don't tell git that your local branch (master) is supposed to compare itself to the remote counterpart (origin/master in this case); then git status won't tell you the difference between your branch and the remote one. So you should use:

git branch --set-upstream-to origin/master

or with the short option:

git branch -u origin/master

This options --set-upstream-to (or -u in short) was introduced in git 1.8.0.

Once you have set this option; git status will show you something like:

# Your branch is ahead of 'origin/master' by 1 commit.

Quicker - no. More effective - yes, if you will use the StringBuilder class. With your implementation each operation generates a copy of a string which under circumstances may impair performance. Strings are immutable objects so each operation just returns a modified copy.

If you expect this method to be actively called on multiple Strings of significant length, it might be better to "migrate" its implementation onto the StringBuilder class. With it any modification is performed directly on that instance, so you spare unnecessary copy operations.

public static class StringExtention
{
    public static string clean(this string s)
    {
        StringBuilder sb = new StringBuilder (s);

        sb.Replace("&", "and");
        sb.Replace(",", "");
        sb.Replace("  ", " ");
        sb.Replace(" ", "-");
        sb.Replace("'", "");
        sb.Replace(".", "");
        sb.Replace("eacute;", "é");

        return sb.ToString().ToLower();
    }
}

All the methods above do not handle deep cloning of objects where it is nested to n levels. I did not check its performance over others but it is short and simple.

The first example below shows object cloning using Object.assign which clones just till first level.

var person = {_x000D_
    name:'saksham',_x000D_
    age:22,_x000D_
    skills: {_x000D_
        lang:'javascript',_x000D_
        experience:5_x000D_
    }_x000D_
}_x000D_
_x000D_
newPerson = Object.assign({},person);_x000D_
newPerson.skills.lang = 'angular';_x000D_
console.log(newPerson.skills.lang); //logs Angular

Using the below approach deep clones object

var person = {_x000D_
    name:'saksham',_x000D_
    age:22,_x000D_
    skills: {_x000D_
        lang:'javascript',_x000D_
        experience:5_x000D_
    }_x000D_
}_x000D_
_x000D_
anotherNewPerson = JSON.parse(JSON.stringify(person));_x000D_
anotherNewPerson.skills.lang = 'angular';_x000D_
console.log(person.skills.lang); //logs javascript

Simply add class="img-responsive" to the video tag. I'm doing this on a current project, and it works. It doesn't need to be wrapped in anything.

<video class="img-responsive" src="file.mp4" autoplay loop/>

If you're ok with using a third party library, check out traex/RippleEffect. It allows you to add a Ripple effect to ANY view with just a few lines of code. You just need to wrap, in your xml layout file, the element you want to have a ripple effect with a com.andexert.library.RippleView container.

As an added bonus it requires Min SDK 9 so you can have design consistency across OS versions.

Here's an example taken from the libraries' GitHub repo:

<com.andexert.library.RippleView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:rv_centered="true">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@android:drawable/ic_menu_edit"
        android:background="@android:color/holo_blue_dark"/> 

</com.andexert.library.RippleView>

You can change the ripple colour by adding this attribute the the RippleView element: app:rv_color="@color/my_fancy_ripple_color

You can use multiple ordering on multiple condition,

ORDER BY 
     (CASE 
        WHEN @AlphabetBy = 2  THEN [Drug Name]
      END) ASC,
    CASE 
        WHEN @TopBy = 1  THEN [Rx Count]
        WHEN @TopBy = 2  THEN [Cost]
        WHEN @TopBy = 3  THEN [Revenue]
    END DESC 

Also, if you want to overwrite messages in the same line, for instance in a countdown, you could add '\r' at the end of the string.

process.stdout.write("Downloading " + data.length + " bytes\r");

ponder Try Heap. I believe it's the most consistent of the O(n lg n) sorts.

If you are looking to do this from Windows 10 IoT, then there is a built in command you can use:

By column name:

In [20]: df = pd.DataFrame({'x' : [1, 2, 3, 4], 'y' : [4, 5, 6, 7]})
In [21]: df
Out[21]:
    x   y
0   1   4
1   2   5
2   3   6
3   4   7

In [23]: df.x
Out[23]:
0    1
1    2

1. git reset --hard CommitId
2. git push -f origin master

1st command will rest your head to commitid and 2nd command will delete all commit after that commit id on master branch.

Note: Don't forget to add -f in push otherwise it will be rejected.

Wont the below basic approach doesn't suffice your requirements?

I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.

It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.

CREATE USER myNewUser WITH PASSWORD 'passWord';

will create a user with the username 'mynewuser' and password 'passWord'.

This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.

The data-role="none" is the key to make them work together. You can apply to the elements you want bootstrap to touch but jquery mobile to ignore. like this input type="text" class="form-control" placeholder="Search" data-role="none"

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

When you specify a percentage for max-height on a child, it is a percentage of the parent's actual height, not the parent's max-height, oddly enough. The same applies to max-width.

So, when you don't specify an explicit height on the parent, then there's no base height for the child's max-height to be calculated from, so max-height computes to none, allowing the child to be as tall as possible. The only other constraint acting on the child now is the max-width of its parent, and since the image itself is taller than it is wide, it overflows the container's height downwards, in order to maintain its aspect ratio while still being as large as possible overall.

When you do specify an explicit height for the parent, then the child knows it has to be at most 100% of that explicit height. That allows it to be constrained to the parent's height (while still maintaining its aspect ratio).

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '

SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

Here is a way to write data from a dataframe into an excel file by different IDs and into different tabs (sheets) by another ID associated to the first level id. Imagine you have a dataframe that has email_address as one column for a number of different users, but each email has a number of 'sub-ids' that have all the data.

data <- tibble(id = c(1,2,3,4,5,6,7,8,9), email_address = c(rep('[email protected]',3), rep('[email protected]', 3), rep('[email protected]', 3)))

So ids 1,2,3 would be associated with [email protected]. The following code splits the data by email and then puts 1,2,3 into different tabs. The important thing is to set append = True when writing the .xlsx file.

temp_dir <- tempdir()

for(i in unique(data$email_address)){
    
  data %>% 
    filter(email_address == i) %>% 
    arrange(id) -> subset_data
  
  for(j in unique(subset_data$id)){
    write.xlsx(subset_data %>% filter(id == j), 
      file = str_c(temp_dir,"/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0- 
       9._%+-]+"),'_', Sys.Date(), '.xlsx'), 
      sheetName = as.character(j), 
      append = TRUE)}
 
  }

The regex gets the name from the email address and puts it into the file-name.

Hope somebody finds this useful. I'm sure there's more elegant ways of doing this but it works.

Btw, here is a way to then send these individual files to the various email addresses in the data.frame. Code goes into second loop [j]

  send.mail(from = "[email protected]",
            to = i,
          subject = paste("Your report for", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"), 'on', Sys.Date()),
          body = "Your email body",
          authenticate = TRUE,
          smtp = list(host.name = "XXX", port = XXX,
                      user.name = Sys.getenv("XXX"), passwd = Sys.getenv("XXX")),
          attach.files = str_c(temp_dir, "/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"),'_', Sys.Date(), '.xlsx'))

This is an easy way for any format. Just change it to required format string

XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);

jQuery uses a .call(...) method to assign the current node to this inside the function you pass as the parameter.

EDIT:

Don't be afraid to look inside jQuery's code when you have a doubt, it's all in clear and well documented Javascript.

ie: the answer to this question is around line 574,
callback.call( object[ name ], name, object[ name ] ) === false

Use switch every time you have more than 2 conditions on a single variable, take weekdays for example, if you have a different action for every weekday you should use a switch.

Other situations (multiple variables or complex if clauses you should Ifs, but there isn't a rule on where to use each.

Go to File > Source Control > Go Online, select the files you changed, and finish the process.

I hope this answer is still useful, despite problem seems to be quite old.

If you have Anaconda installed, and your OpenCV does not support GTK+ (as in this case), you can simply type

conda install -c menpo opencv=2.4.11

It will install suitable OpenCV version that does not produce a mentioned error. Besides, it will reinstall previously installed OpenCV if there was one as a part of Anaconda.

This worked for me:

from matplotlib import pyplot as plt
from IPython.display import clear_output
import numpy as np
for i in range(50):
    clear_output(wait=True)
    y = np.random.random([10,1])
    plt.plot(y)
    plt.show()
