As, said by @Agaline, i download the outside wheel from this Christoph Gohlke.

If your is Python 3.7 then try to PyAudio-0.2.11-cp37-cp37m-win_amd64.whl and use command as, go to the download directroy and:

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl and it works.

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',
  body: formData
})
.then(r => r.json())
.then(data => {
  console.log(data)
})

Follow the steps that are described on this answer just instead of using the drop down, type the port (8787) in "port range" an then "Add rule".

Go to the "Network & Security" -> Security Group settings in the left hand navigation

Find the Security Group that your instance is apart of Click on Inbound Rules Use the drop down and add HTTP (port 80) Click Apply and enjoy

Overview of Scanner.hasNextXXX methods

java.util.Scanner has many hasNextXXX methods that can be used to validate input. Here's a brief overview of all of them:

• hasNext() - does it have any token at all?
• hasNextLine() - does it have another line of input?
• For Java primitives
  • hasNextInt() - does it have a token that can be parsed into an int?
  • Also available are hasNextDouble(), hasNextFloat(), hasNextByte(), hasNextShort(), hasNextLong(), and hasNextBoolean()
  • As bonus, there's also hasNextBigInteger() and hasNextBigDecimal()
  • The integral types also has overloads to specify radix (for e.g. hexadecimal)
• Regular expression-based
  • hasNext(String pattern)
  • hasNext(Pattern pattern) is the Pattern.compile overload

Scanner is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern), which lets you define what pattern separates your tokens. There are also find and skip methods that ignores delimiters.

The following discussion will keep the regex as simple as possible, so the focus remains on Scanner.

Example 1: Validating positive ints

Here's a simple example of using hasNextInt() to validate positive int from the input.

Scanner sc = new Scanner(System.in);
int number;
do {
    System.out.println("Please enter a positive number!");
    while (!sc.hasNextInt()) {
        System.out.println("That's not a number!");
        sc.next(); // this is important!
    }
    number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);

Here's an example session:

Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5

Note how much easier Scanner.hasNextInt() is to use compared to the more verbose try/catch Integer.parseInt/NumberFormatException combo. By contract, a Scanner guarantees that if it hasNextInt(), then nextInt() will peacefully give you that int, and will not throw any NumberFormatException/InputMismatchException/NoSuchElementException.

Related questions

• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Example 2: Multiple hasNextXXX on the same token

Note that the snippet above contains a sc.next() statement to advance the Scanner until it hasNextInt(). It's important to realize that none of the hasNextXXX methods advance the Scanner past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!

This has two consequences:

• If you need to skip the "garbage" input that fails your hasNextXXX test, then you need to advance the Scanner one way or another (e.g. next(), nextLine(), skip, etc).
• If one hasNextXXX test fails, you can still test if it perhaps hasNextYYY!

Here's an example of performing multiple hasNextXXX tests.

Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
    System.out.println(
        sc.hasNextInt() ? "(int) " + sc.nextInt() :
        sc.hasNextLong() ? "(long) " + sc.nextLong() :  
        sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
        sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
        "(String) " + sc.next()
    );
}

Here's an example session:

5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit

Note that the order of the tests matters. If a Scanner hasNextInt(), then it also hasNextLong(), but it's not necessarily true the other way around. More often than not you'd want to do the more specific test before the more general test.

Example 3 : Validating vowels

Scanner has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.

Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
    System.out.println("That's not a vowel!");
    sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);

Here's an example session:

Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e

In regex, as a Java string literal, the pattern "[aeiou]" is what is called a "character class"; it matches any of the letters a, e, i, o, u. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner.

Example 4: Using two Scanner at once

Sometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner, where the second Scanner takes the nextLine() from the first Scanner as input. Here's an example:

Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
    Scanner lineSc = new Scanner(sc.nextLine());
    int sum = 0;
    while (lineSc.hasNextInt()) {
        sum += lineSc.nextInt();
    }
    System.out.println("Sum is " + sum);
}

Here's an example session:

Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit

In addition to Scanner(String) constructor, there's also Scanner(java.io.File) among others.

Summary

• Scanner provides a rich set of features, such as hasNextXXX methods for validation.
• Proper usage of hasNextXXX/nextXXX in combination means that a Scanner will NEVER throw an InputMismatchException/NoSuchElementException.
• Always remember that hasNextXXX does not advance the Scanner past any input.
• Don't be shy to create multiple Scanner if necessary. Two simple Scanner is often better than one overly complex Scanner.
• Finally, even if you don't have any plans to use the advanced regex features, do keep in mind which methods are regex-based and which aren't. Any Scanner method that takes a String pattern argument is regex-based.
  • Tip: an easy way to turn any String into a literal pattern is to Pattern.quote it.

I know this is really a really old question, but I was trying to do the same thing and I stumbled upon a new formula in excel called "TEXTJOIN".

For the question, the following formula solves the problem

=TEXTJOIN("",TRUE,(a1:a4))

The signature of "TEXTJOIN" is explained as TEXTJOIN(delimiter,ignore_empty,text1,[text2],[text3],...)

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

Another option, very late in coming, sorry:

http://www.architectshack.com/TextFileEncodingDetector.ashx

This small C#-only class uses BOMS if present, tries to auto-detect possible unicode encodings otherwise, and falls back if none of the Unicode encodings is possible or likely.

It sounds like UTF8Checker referenced above does something similar, but I think this is slightly broader in scope - instead of just UTF8, it also checks for other possible Unicode encodings (UTF-16 LE or BE) that might be missing a BOM.

Hope this helps someone!

Since you are interested in catching network related errors and HTTP errors, the following provides a better approach:

function curl_error_test($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $responseBody = curl_exec($ch);
    /*
     * if curl_exec failed then
     * $responseBody is false
     * curl_errno() returns non-zero number
     * curl_error() returns non-empty string
     * which one to use is up too you
     */
    if ($responseBody === false) {
        return "CURL Error: " . curl_error($ch);
    }

    $responseCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    /*
     * 4xx status codes are client errors
     * 5xx status codes are server errors
     */
    if ($responseCode >= 400) {
        return "HTTP Error: " . $responseCode;
    }

    return "No CURL or HTTP Error";
}

Tests:

curl_error_test("http://expamle.com");          // CURL Error: Could not resolve host: expamle.com
curl_error_test("http://example.com/whatever"); // HTTP Error: 404
curl_error_test("http://example.com");          // No CURL or HTTP Error

Reading a file in and by itself takes some time, garbage collecting the result is another problem as you read the whole file just to count the newline character(s),

At some point, someone is going to have to read the characters in the file, regardless if this the framework or if it is your code. This means you have to open the file and read it into memory if the file is large this is going to potentially be a problem as the memory needs to be garbage collected.

Nima Ara made a nice analysis that you might take into consideration

Here is the solution proposed, as it reads 4 characters at a time, counts the line feed character and re-uses the same memory address again for the next character comparison.

private const char CR = '\r';  
private const char LF = '\n';  
private const char NULL = (char)0;

public static long CountLinesMaybe(Stream stream)  
{
    Ensure.NotNull(stream, nameof(stream));

    var lineCount = 0L;

    var byteBuffer = new byte[1024 * 1024];
    const int BytesAtTheTime = 4;
    var detectedEOL = NULL;
    var currentChar = NULL;

    int bytesRead;
    while ((bytesRead = stream.Read(byteBuffer, 0, byteBuffer.Length)) > 0)
    {
        var i = 0;
        for (; i <= bytesRead - BytesAtTheTime; i += BytesAtTheTime)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 1];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 2];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 3];
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
                i -= BytesAtTheTime - 1;
            }
        }

        for (; i < bytesRead; i++)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
            }
        }
    }

    if (currentChar != LF && currentChar != CR && currentChar != NULL)
    {
        lineCount++;
    }
    return lineCount;
}

Above you can see that a line is read one character at a time as well by the underlying framework as you need to read all characters to see the line feed.

If you profile it as done bay Nima you would see that this is a rather fast and efficient way of doing this.

There is a new library called ipyvolume that may do what you want, the documentation shows live demos. The current version doesn't do meshes and lines, but master from the git repo does (as will version 0.4). (Disclaimer: I'm the author)

If you assign value 0 to item.selectedVariant it should be selected automatically. Check out sample on http://docs.angularjs.org/api/ng.directive:select which selects red color by default by simply assigning $scope.color='red'.

I think sim serial Number and sim number is unique. You can try this for get sim serial number and get sim number and Don't forget to add permission in manifest file.

TelephonyManager telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
String getSimNumber = telemamanger.getLine1Number();

And add below permission into your Androidmanifest.xml file.

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

Let me know if there is any issue.

all numbers are stored in binary. if you want a textual representation of a given number in binary, use bin(i)

>>> bin(10)
'0b1010'
>>> 0b1010
10

I expanded the Bootstrap table styles as Davide Pastore did, but with that method the styles are applied to all child tables as well, and they don't apply to the footer.

A better solution would be imitating the core Bootstrap table styles, but with your new class:

.table-borderless>thead>tr>th
.table-borderless>thead>tr>td
.table-borderless>tbody>tr>th
.table-borderless>tbody>tr>td
.table-borderless>tfoot>tr>th
.table-borderless>tfoot>tr>td {
    border: none;
}

Then when you use <table class='table table-borderless'> only the specific table with the class will be bordered, not any table in the tree.

I ran into a similar issue today - my ruby version didn't match my rvm installs.

> ruby -v
ruby 2.0.0p481

> rvm list
rvm rubies
   ruby-2.1.2 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
   ruby-2.2.3 [ x86_64 ]

Also, rvm current failed.

> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...

The error message recommended this useful command, which resolved the issue for me:

> rvm get stable --auto-dotfiles

IF EXISTS (SELECT NAME FROM SYS.OBJECTS WHERE object_id = OBJECT_ID(N'Scores') AND TYPE in (N'U'))
    DROP TABLE Scores
GO

Another way of escaping the apostrophe is to write a string literal:

insert into Person (First, Last) values (q'[Joe]', q'[O'Brien]')

This is a better approach, because:

1. Imagine you have an Excel list with 1000's of names you want to upload to your database. You may simply create a formula to generate 1000's of INSERT statements with your cell contents instead of looking manually for apostrophes.

2. It works for other escape characters too. For example loading a Regex pattern value, i.e. ^( *)(P|N)?( *)|( *)((<|>)\d\d?)?( *)|( )(((?i)(in|not in)(?-i) ?(('[^']+')(, ?'[^']+'))))?( *)$ into a table.

Android has build-in patterns for email, phone number, etc, that you can use if you are building for Android API level 8 and above.

private boolean isValidEmail(CharSequence email) {
    if (!TextUtils.isEmpty(email)) {
        return Patterns.EMAIL_ADDRESS.matcher(email).matches();
    }
    return false;
}

private boolean isValidPhoneNumber(CharSequence phoneNumber) {
    if (!TextUtils.isEmpty(phoneNumber)) {
        return Patterns.PHONE.matcher(phoneNumber).matches();
    }
    return false;
}

You can simplify the code like this.

In Java:

new Handler().postDelayed (() -> {
    //your code here
}, 1000);

In Kotlin:

Handler().postDelayed({
   //your code here
}, 1000)

Note that Git 1.9/2.0 (Q1 2014) has removed that limitation.
See commit 82fba2b, from Nguy?n Thái Ng?c Duy (pclouds):

Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore.

The documentation now reads:

--depth <depth>::

Create a 'shallow' clone with a history truncated to the specified number of revisions.

That stems from commits like 0d7d285, f2c681c, and c29a7b8 which support clone, send-pack /receive-pack with/from shallow clones.
smart-http now supports shallow fetch/clone too.

All the details are in "shallow.c: the 8 steps to select new commits for .git/shallow".

Update June 2015: Git 2.5 will even allow for fetching a single commit!
(Ultimate shallow case)

Update January 2016: Git 2.8 (Mach 2016) now documents officially the practice of getting a minimal history.
See commit 99487cf, commit 9cfde9e (30 Dec 2015), commit 9cfde9e (30 Dec 2015), commit bac5874 (29 Dec 2015), and commit 1de2e44 (28 Dec 2015) by Stephen P. Smith (``).
^{(Merged by Junio C Hamano -- gitster -- in commit 7e3e80a, 20 Jan 2016)}

This is "Documentation/user-manual.txt"

A <<def_shallow_clone,shallow clone>> is created by specifying the git-clone --depth switch.
The depth can later be changed with the git-fetch --depth switch, or full history restored with --unshallow.

Merging inside a <<def_shallow_clone,shallow clone>> will work as long as a merge base is in the recent history.
Otherwise, it will be like merging unrelated histories and may have to result in huge conflicts.
This limitation may make such a repository unsuitable to be used in merge based workflows.

Update 2020:

• git 2.11.1 introduced option git fetch --shallow-exclude= to prevent fetching all history
• git 2.11.1 introduced option git fetch --shallow-since= to prevent fetching old commits.

For more on the shallow clone update process, see "How to update a git shallow clone?".

As commented by Richard Michael:

to backfill history: git pull --unshallow

And Olle Härstedt adds in the comments:

To backfill part of the history: git fetch --depth=100.

Just is case somebody asks (like I did), this is also possible when one uses subplot2grid. For example:

import matplotlib.pyplot as plt
plt.subplot2grid((3,2), (0,1), rowspan=3)
plt.plot([2,3,4,5])
plt.tick_params(axis='y', which='both', labelleft='off', labelright='on')
plt.show()

It will show this:

Assuming that you're talking about desktop and not web applications:

When you add settings to a project, VS creates a file named app.config in your project directory and stores the settings in that file. It also builds the Settings.cs file that provides the static accessors to the individual settings.

At compile time, VS will (by default; you can change this) copy the app.config to the build directory, changing its name to match the executable (e.g. if your executable is named foo.exe, the file will be named foo.exe.config), which is the name the .NET configuration manager looks for when it retrieves settings at runtime.

If you change a setting through the VS settings editor, it will update both app.config and Settings.cs. (If you look at the property accessors in the generated code in Settings.cs, you'll see that they're marked with an attribute containing the default value of the setting that's in your app.config file.) If you change a setting by editing the app.config file directly, Settings.cs won't be updated, but the new value will still be used by your program when you run it, because app.config gets copied to foo.exe.config at compile time. If you turn this off (by setting the file's properties), you can change a setting by directly editing the foo.exe.config file in the build directory.

Then there are user-scoped settings.

Application-scope settings are read-only. Your program can modify and save user-scope settings, thus allowing each user to have his/her own settings. These settings aren't stored in the foo.exe.config file (since under Vista, at least, programs can't write to any subdirectory of Program Files without elevation); they're stored in a configuration file in the user's application data directory.

The path to that file is %appdata%\%publisher_name%\%program_name%\%version%\user.config, e.g. C:\Users\My Name\AppData\Local\My_Company\My_Program.exe\1.0.0\user.config. Note that if you've given your program a strong name, the strong name will be appended to the program name in this path.

Use os.path.join to concatenate the directory and file name:

for path, subdirs, files in os.walk(root):
    for name in files:
        print(os.path.join(path, name))

Note the usage of path and not root in the concatenation, since using root would be incorrect.

In Python 3.4, the pathlib module was added for easier path manipulations. So the equivalent to os.path.join would be:

pathlib.PurePath(path, name)

The advantage of pathlib is that you can use a variety of useful methods on paths. If you use the concrete Path variant you can also do actual OS calls through them, like changing into a directory, deleting the path, opening the file it points to and much more.

.center {
  display: table;
  margin: auto;
}

There is a space missing between elif and [:

elif[ "$seconds" -gt 0 ]

should be

elif [ "$seconds" -gt 0 ]

As I see this question is getting a lot of views, it is important to indicate that the syntax to follow is:

if [ conditions ]
# ^ ^          ^

meaning that spaces are needed around the brackets. Otherwise, it won't work. This is because [ itself is a command.

The reason why you are not seeing something like elif[: command not found (or similar) is that after seeing if and then, the shell is looking for either elif, else, or fi. However it finds another then (after the mis-formatted elif[). Only after having parsed the statement it would be executed (and an error message like elif[: command not found would be output).

Question - is this case proven to be the result of lock escalation (i.e. if you trace with profiler for lock escalation events, is that definitely what is happening to cause the blocking)? If so, there is a full explanation and a (rather extreme) workaround by enabling a trace flag at the instance level to prevent lock escalation. See http://support.microsoft.com/kb/323630 trace flag 1211

But, that will likely have unintended side effects.

If you are deliberately locking a row and keeping it locked for an extended period, then using the internal locking mechanism for transactions isn't the best method (in SQL Server at least). All the optimization in SQL Server is geared toward short transactions - get in, make an update, get out. That's the reason for lock escalation in the first place.

So if the intent is to "check out" a row for a prolonged period, instead of transactional locking it's best to use a column with values and a plain ol' update statement to flag the rows as locked or not.

No one has provided a solution that would work cross-form. I know it wasn't specifically asked but I am working in a linux environment where most of the solutions (as at the time I post this) would provide an error.

Hardcoding path separators (as well as other things) will give an error in anything but Windows systems.

In my original solution I used:

char filesep = Path.DirectorySeparatorChar;
string datapath = $"..{filesep}..{filesep}";

However after seeing some of the answers here I adjusted it to be:

string datapath = Directory.GetParent(Directory.GetParent(Directory.GetCurrentDirectory()).FullName).FullName; 

If the pop-up's document is from a different domain, this is simply not possible.

Update April 2015: I was wrong about this: if you own both domains, you can use window.postMessage and the message event in pretty much all browsers that are relevant today.

If not, there's still no way you'll be able to make this work cross-browser without some help from the document being loaded into the pop-up. You need to be able to detect a change in the pop-up that occurs once it has loaded, which could be a variable that JavaScript in the pop-up page sets when it handles its own load event, or if you have some control of it you could add a call to a function in the opener.

If you are running against IIS rather than the VS webdev server, ensure that Index.aspx is one of your default files and that directory browsing is turned off.

Continuing from Pete's example above, to do it directly in the cmd window, use a single %, eg:

cd c:\test\folder A
for %X in (*)do echo %~nxX

(Note that special files like desktop.ini will not show up.)

It's also possible to redirect the output to a file using >>:

cd c:\test\folder A
for %X in (*)do echo %~nxX>>c:\test\output.txt

For a real example, assuming you want to robocopy all files from folder-A to folder-B (non-recursively):

cd c:\test\folder A
for %X in (*)do robocopy . "c:\test\folder B" "%~nxX" /dcopy:dat /copyall /v>>c:\test\output.txt

and for all folders (recursively):

cd c:\test\folder A
for /d %X in (*)do robocopy "%X" "C:\test\folder B\%X" /e /copyall /dcopy:dat /v>>c:\test\output2.txt

Using just awk you could do (I also shortened some of your piping):

strings -a libAddressDoctor5.so | awk '/EngineVersion/ { if(NR==2) { gsub("\"",""); print $2 } }'

I can't verify it for you because I don't know your exact input, but the following works:

echo "Blah EngineVersion=\"123\"" | awk '/EngineVersion/ { gsub("\"",""); print $2 }'

To remove all OIDs from your database tables, you can use this Linux script:

First, login as PostgreSQL superuser:

sudo su postgres

Now run this script, changing YOUR_DATABASE_NAME with you database name:

for tbl in `psql -qAt -c "select schemaname || '.' || tablename from pg_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema';" YOUR_DATABASE_NAME` ; do  psql -c "alter table $tbl SET WITHOUT OIDS" YOUR_DATABASE_NAME ; done

I used this script to remove all my OIDs, since Npgsql 3.0 doesn't work with this, and it isn't important to PostgreSQL anymore.

A build, as Makefile understands it, consists of a lot of targets. For example, to build a project you might need

1. Build file1.o out of file1.c
2. Build file2.o out of file2.c
3. Build file3.o out of file3.c
4. Build executable1 out of file1.o and file3.o
5. Build executable2 out of file2.o

If you implemented this workflow with makefile, you could make each of the targets separately. For example, if you wrote

make file1.o

it would only build that file, if necessary.

The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files. For the example above, building all necessary is building executables, the other files being pulled in as dependencies. So in the makefile it looks like this:

all: executable1 executable2

all target is usually the first in the makefile, since if you just write make in command line, without specifying the target, it will build the first target. And you expect it to be all.

all is usually also a .PHONY target. Learn more here.

If the numeric values are seq indexes, then we could have simpler ways... Here's my code submission, My Ruby is a bit rusty

   input = ["cat", 1, "dog", 2, "wombat", 3]
   hash = Hash.new
   input.each_with_index {|item, index|
     if (index%2 == 0) hash[item] = input[index+1]
   }
   hash   #=> {"cat"=>1, "wombat"=>3, "dog"=>2}

This one $("#yourDiv").load(" #yourDiv > *"); is the best if you are planning to just reload a <div>

Make sure to use an id and not a class. Also, remember to paste <script src="https://code.jquery.com/jquery-3.5.1.js"></script> in the <head> section of the html file, if you haven't already. In opposite case it won't work.

If you are simply interested to know whether a registry value is present or not then how about:

[bool]((Get-itemproperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").PathName)

will return: $true while

[bool]((Get-itemproperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ValueNotThere)

will return: $false as it's not there ;)

You could adapt it into a scriptblock like:

$CheckForRegValue = { Param([String]$KeyPath, [String]$KeyValue)
return [bool]((Get-itemproperty -Path $KeyPath).$KeyValue) }

and then just call it by:

& $CheckForRegValue "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" PathName

The Numerical Recipes website (http://www.nr.com/) has an FFT if you don't mind typing it in. I am working on a project converting a Labview program to C# 2008, .NET 3.5 to acquire data and then look at the frequency spectrum. Unfortunately the Math.Net uses the latest .NET framework, so I couldn't use that FFT. I tried the Exocortex one - it worked but the results to match the Labview results and I don't know enough FFT theory to know what is causing the problem. So I tried the FFT on the numerical recipes website and it worked! I was also able to program the Labview low sidelobe window (and had to introduce a scaling factor).

You can read the chapter of the Numerical Recipes book as a guest on thier site, but the book is so useful that I highly recomend purchasing it. Even if you do end up using the Math.NET FFT.

You can use a query in the AWS Config Console here. (Region may change for you) https://console.aws.amazon.com/config/home?region=us-east-1#/resources/query

the query will look like.

SELECT
  resourceId,
  resourceName,
  resourceType,
  relationships
WHERE
relationships.resourceId = 'vpc-#######'

You need to wrap the table inside another element and set the height of that element. Example with inline css:

<div style="height: 500px; overflow: auto;">
 <table>
 </table>
</div>

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

In Vim you can also use gJ.

I'm a little surprised nobody has suggested the most obvious solution:

grep -v '^#' filename

This solves the problem as stated.

But note that a common convention is for everything from a # to the end of a line to be treated as a comment:

sed 's/#.*$//' filename

though that treats, for example, a # character within a string literal as the beginning of a comment (which may or may not be relevant for your case) (and it leaves empty lines).

A line starting with arbitrary whitespace followed by # might also be treated as a comment:

grep -v '^ *#' filename

if whitespace is only spaces, or

grep -v '^[  ]#' filename

where the two spaces are actually a space followed by a literal tab character (type "control-v tab").

For all these commands, omit the filename argument to read from standard input (e.g., as part of a pipe).

The hex values are on the mainpage of http://glyphicons.com/ in the tooltips of the specific icon.

I used a custom ScrollView made in Kotlin which uses maxHeight. Example of use:

<com.antena3.atresplayer.tv.ui.widget.ScrollViewWithMaxHeight
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxHeight="100dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
</com.antena3.atresplayer.tv.ui.widget.ScrollViewWithMaxHeight>

Here is the code of ScrollViewWidthMaxHeight:

import android.content.Context
import android.util.AttributeSet
import android.widget.ScrollView
import timber.log.Timber

class ScrollViewWithMaxHeight @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = 0
) : ScrollView(context, attrs, defStyleAttr) {

companion object {
    var WITHOUT_MAX_HEIGHT_VALUE = -1
}

private var maxHeight = WITHOUT_MAX_HEIGHT_VALUE

init {
    val a = context.obtainStyledAttributes(
        attrs, R.styleable.ScrollViewWithMaxHeight,
        defStyleAttr, 0
    )
    try {
        maxHeight = a.getDimension(
            R.styleable.ScrollViewWithMaxHeight_android_maxHeight,
            WITHOUT_MAX_HEIGHT_VALUE.toFloat()
        ).toInt()
    } finally {
        a.recycle()
    }
}

override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
    var heightMeasure = heightMeasureSpec
    try {
        var heightSize = MeasureSpec.getSize(heightMeasureSpec)
        if (maxHeight != WITHOUT_MAX_HEIGHT_VALUE) {
            heightSize = maxHeight
            heightMeasure = MeasureSpec.makeMeasureSpec(heightSize, MeasureSpec.AT_MOST)
        } else {
            heightMeasure = MeasureSpec.makeMeasureSpec(heightSize, MeasureSpec.UNSPECIFIED)
        }
        layoutParams.height = heightSize
    } catch (e: Exception) {
        Timber.e(e, "Error forcing height")
    } finally {
        super.onMeasure(widthMeasureSpec, heightMeasure)
    }
}

fun setMaxHeight(maxHeight: Int) {
    this.maxHeight = maxHeight
}
}

which needs also this declaration in values/attrs.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="ScrollViewWithMaxHeight">
        <attr name="android:maxHeight" />
    </declare-styleable>
</resources>

I found a perfect and simple method. The auto layout does not allow you to resize the spaces equally, but it does allow you to resize views equally. Simply put some invisible views in between your fields and tell auto layout to keep them the same size. It works perfectly!

One thing of note though; when I reduced the size in the interface designer, sometimes it got confused and left a label where it was, and it had a conflict if the size was changed by an odd amount. Otherwise it worked perfectly.

edit: I found that the conflict became a problem. Because of that, I took one of the spacing constraints, deleted it and replaced it with two constraints, a greater-than-or-equal and a less-than-or-equal. Both were the same size and had a much lower priority than the other constraints. The result was no further conflict.

This means that your selectedindex is out of the range of the array of items in the combobox. The array of items in your combo box is zero-based, so if you have 2 items, it's item 0 and item 1.

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

This is all I know how to do though sorry.

counter=0
ipcounter=0
tcpcounter=0
udpcounter=0

filename='sampledata.pcap'

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

    counter+=1
    eth=dpkt.ethernet.Ethernet(pkt) 
    if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
       continue

    ip=eth.data
    ipcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_TCP: 
       tcpcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_UDP:
       udpcounter+=1

print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

You could use the static StartupPath property of the Application class.

Wikipedia's Segmentation_fault page has a very nice description about it, just pointing out the causes and reasons. Have a look into the wiki for a detailed description.

In computing, a segmentation fault (often shortened to segfault) or access violation is a fault raised by hardware with memory protection, notifying an operating system (OS) about a memory access violation.

The following are some typical causes of a segmentation fault:

• Dereferencing NULL pointers – this is special-cased by memory management hardware
• Attempting to access a nonexistent memory address (outside process's address space)
• Attempting to access memory the program does not have rights to (such as kernel structures in process context)
• Attempting to write read-only memory (such as code segment)

These in turn are often caused by programming errors that result in invalid memory access:

• Dereferencing or assigning to an uninitialized pointer (wild pointer, which points to a random memory address)

• Dereferencing or assigning to a freed pointer (dangling pointer, which points to memory that has been freed/deallocated/deleted)

• A buffer overflow.

• A stack overflow.

• Attempting to execute a program that does not compile correctly. (Some compilers will output an executable file despite the presence of compile-time errors.)

To reduce the complexity and simplify the language, multiple inheritance is not supported in java.

Consider a scenario where A, B and C are three classes. The C class inherits A and B classes. If A and B classes have same method and you call it from child class object, there will be ambiguity to call method of A or B class.

Since compile time errors are better than runtime errors, java renders compile time error if you inherit 2 classes. So whether you have same method or different, there will be compile time error now.

class A {  
    void msg() {
        System.out.println("From A");
    }  
}

class B {  
    void msg() {
        System.out.println("From B");
    }  
}

class C extends A,B { // suppose if this was possible
    public static void main(String[] args) {  
        C obj = new C();  
        obj.msg(); // which msg() method would be invoked?  
    }
} 

I used this set of code to find the file length.

//opens a file with a file descriptor
FILE * i_file;
i_file = fopen(source, "r");

//gets a long from the file descriptor for fstat
long f_d = fileno(i_file);
struct stat buffer;
fstat(f_d, &buffer);

//stores file size
long file_length = buffer.st_size;
fclose(i_file);

There are many ways to do this, one way is:

sqlite3 auction.db

Followed by:

sqlite> .read create.sql

In general, the SQLite project has really fantastic documentation! I know we often reach for Google before the docs, but in SQLite's case, the docs really are technical writing at its best. It's clean, clear, and concise.

Every programming language has its own way of structuring the code.
whenever you write a block of code, it has to be organised in a way to be understood by everyone.

Usually used in conditional and classes and defining the definition.
It represents the parent, child and grandchild and further.

Example:

def example()
    print "name"
    print "my name"
example()

Here you can say example() is a parent and others are children.

If you are just looping through 10k rows in column A, then dump the row into a variant array and then loop through that.

You can then either add the elements to a new array (while adding rows when needed) and using Transpose() to put the array onto your range in one move, or you can use your iterator variable to track which row you are on and add rows that way.

Dim i As Long
Dim varray As Variant

varray = Range("A2:A" & Cells(Rows.Count, "A").End(xlUp).Row).Value

For i = 1 To UBound(varray, 1)
    ' do stuff to varray(i, 1)
Next

Here is an example of how you could add rows after evaluating each cell. This example just inserts a row after every row that has the word "foo" in column A. Not that the "+2" is added to the variable i during the insert since we are starting on A2. It would be +1 if we were starting our array with A1.

Sub test()

Dim varray As Variant
Dim i As Long

varray = Range("A2:A10").Value

'must step back or it'll be infinite loop
For i = UBound(varray, 1) To LBound(varray, 1) Step -1
    'do your logic and evaluation here
    If varray(i, 1) = "foo" Then
       'not how to offset the i variable 
       Range("A" & i + 2).EntireRow.Insert
    End If
Next

End Sub

Thanks for referencing my blog post at http://mbccs.blogspot.com/2007/11/fixing-window-resize-event-in-ie.html.

While you can just hook up to the standard window resize event, you'll find that in IE, the event is fired once for every X and once for every Y axis movement, resulting in a ton of events being fired which might have a performance impact on your site if rendering is an intensive task.

My method involves a short timeout that gets cancelled on subsequent events so that the event doesn't get bubbled up to your code until the user has finished resizing the window.

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

This is my version of a bash script. It takes database name as a parameter and converts all tables to another charset and collation (given by another parameters or default value defined in the script).

#!/bin/bash

# mycollate.sh <database> [<charset> <collation>]
# changes MySQL/MariaDB charset and collation for one database - all tables and
# all columns in all tables

DB="$1"
CHARSET="$2"
COLL="$3"

[ -n "$DB" ] || exit 1
[ -n "$CHARSET" ] || CHARSET="utf8mb4"
[ -n "$COLL" ] || COLL="utf8mb4_general_ci"

echo $DB
echo "ALTER DATABASE $DB CHARACTER SET $CHARSET COLLATE $COLL;" | mysql

echo "USE $DB; SHOW TABLES;" | mysql -s | (
    while read TABLE; do
        echo $DB.$TABLE
        echo "ALTER TABLE $TABLE CONVERT TO CHARACTER SET $CHARSET COLLATE $COLL;" | mysql $DB
    done
)

A JSON object is simply a Javascript object. That's actually what JSON stands for: JavaScript Object Notation. So you'd traverse a JSON object however you'd choose to "traverse" a Javascript object in general.

In ES2017 you would do:

Object.entries(jsonObj).forEach(([key, value]) => {
    // do something with key and val
});

You can always write a function to recursively descend into the object:

function traverse(jsonObj) {
    if( jsonObj !== null && typeof jsonObj == "object" ) {
        Object.entries(jsonObj).forEach(([key, value]) => {
            // key is either an array index or object key
            traverse(value);
        });
    }
    else {
        // jsonObj is a number or string
    }
}

This should be a good starting point. I highly recommend using modern javascript methods for such things, since they make writing such code much easier.

In addition to how Java defines static inner classes, there is another definition of static classes as per the C# world [1]. A static class is one that has only static methods (functions) and it is meant to support procedural programming. Such classes aren't really classes in that the user of the class is only interested in the helper functions and not in creating instances of the class. While static classes are supported in C#, no such direct support exists in Java. You can however use enums to mimic C# static classes in Java so that a user can never create instances of a given class (even using reflection) [2]:

public enum StaticClass2 {
    // Empty enum trick to avoid instance creation
    ; // this semi-colon is important

    public static boolean isEmpty(final String s) {
        return s == null || s.isEmpty();
    }
}

Is there some reason why you think that:

while(in.hasNext())
{
    in.next();
    words++;
}

will not consume the entire input stream?

It will do so, meaning that your other two while loops will never iterate. That's why your values for words and lines are still set to zero.

You're probably better off reading the file one character at a time, increasing the character count each time through the loop, and also detecting the character to decide whether or not to increment the other counters.

Basically, wherever you find a \n, increase the line count - you should probably also do this if the last character in the stream wasn't \n.

And, whenever you transition from white-space to non-white-space, increase the word count (there'll probably be some tricky edge case processing at the stream beginning but that's an implementation issue).

You're looking at something like the following pseudo-code:

# Init counters and last character

charCount = 0
wordCount = 0
lineCount = 0
lastChar = ' '

# Start loop.

currChar = getNextChar()
while currChar != EOF:
    # Every character counts.

    charCount++;

    # Words only on whitespace transitions.

    if isWhite(lastChar) && !isWhite(currChar):
        wordCount++

    # Lines only on newline characters.

    if currChar == '\n':
        lineCount++;
    lastChar = currChar
    currChar = getNextChar()

# Handle incomplete last line.

if lastChar != '\n':
    lineCount++;

My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type.

You are sort of correct. You are allowed to initialize static const integrals in the class declaration but that is not a definition.

http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlcpp8a.doc/language/ref/cplr038.htm

Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line).

Any idea as to what's going on?

std::min takes its parameters by const reference. If it took them by value you'd not have this problem but since you need a reference you also need a definition.

Here's chapter/verse:

9.4.2/4 - If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

See Chu's answer for a possible workaround.

It only comes when your list or dictionary not available in the local function.

Hadoop comes with a useful program called distcp for copying large amounts of data to and from Hadoop Filesystems in parallel. The canonical use case for distcp is for transferring data between two HDFS clusters. If the clusters are running identical versions of hadoop, then the hdfs scheme is appropriate to use.

$ hadoop distcp hdfs://namenode1/foo hdfs://namenode2/bar

The data in /foo directory of namenode1 will be copied to /bar directory of namenode2. If the /bar directory does not exist, it will create it. Also we can mention multiple source paths.

Similar to rsync command, distcp command by default will skip the files that already exist. We can also use -overwrite option to overwrite the existing files in destination directory. The option -update will only update the files that have changed.

$ hadoop distcp -update hdfs://namenode1/foo hdfs://namenode2/bar/foo

distcp can also be implemented as a MapReduce job where the work of copying is done by the maps that run in parallel across the cluster. There will be no reducers.

If trying to copy data between two HDFS clusters that are running different versions, the copy will process will fail, since the RPC systems are incompatible. In that case we need to use the read-only HTTP based HFTP filesystems to read from the source. Here the job has to run on destination cluster.

$ hadoop distcp hftp://namenode1:50070/foo hdfs://namenode2/bar

50070 is the default port number for namenode's embedded web server.

How about this? It doesn't require so much coding.

<a href="#"><div class="plus">CHANGE</div></a>

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

First a CMP (comparison) instruction is called then one of the following:

jle - jump to line if less than or equal to
jge - jump to line if greater than or equal to

The lowest assembler works with is bytes, not bits (directly anyway). If you want to know about bit logic you'll need to take a look at circuit design.

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

In my case MySQL sever was not running. I restarted the MySQL server and issue was resolved.

//on ubuntu server
sudo /etc/init.d/mysql start

To avoid MySQL stop problem, you can use the "initctl" utility in Ubuntu 14.04 LTS Linux to make sure the service restarts in case of a failure or reboot. Please consider talking a snapshot of root volume (with mysql stopped) before performing this operations for data retention purpose[8]. You can use the following commands to manage the mysql service with "initctl" utility with stop and start operations.

$ sudo initctl stop mysql
$ sudo initctl start mysql

To verify the working, you can check the status of the service and get the process id (pid), simulate a failure by killing the "mysql" process and verify its status as running with new process id after sometime (typically within 1 minute) using the following commands.

$ sudo initctl status mysql         # get pid
$ sudo kill -9 <pid>                # kill mysql process
$ sudo initctl status mysql         # verify status as running after sometime

Note : In latest Ubuntu version now initctl is replaced by systemctl

Pure bash solution

Since bash 5.0 (released on 7 Jan 2019) you can use the built-in variable EPOCHSECONDS.

$ echo $EPOCHSECONDS
1547624774

There is also EPOCHREALTIME which includes fractions of seconds.

$ echo $EPOCHREALTIME
1547624774.371215

EPOCHREALTIME can be converted to micro-seconds (µs) by removing the decimal point. This might be of interest when using bash's built-in arithmetic (( expression )) which can only handle integers.

$ echo ${EPOCHREALTIME/./}
1547624774371215

In all examples from above the printed time values are equal for better readability. In reality the time values would differ since each command takes a small amount of time to be executed.

One way you could do it in SQL Server would be to return the table content as XML (for XML raw), convert the result to a string and then replace the tags with ", ".

Adding to the crazy ideas: with Python 3 accepting unicode identifiers, you could declare a variable ? = frozenset() (? is U+03D5) and use it instead.

i think it is possible by using below technique

`ts_create` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`ts_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Don't know about git, but in Mercurial I'd just pipe the output of hg log to some sed/perl/whatever script to search for whatever it is you're looking for. You can customize the output of hg log using a template or a style to make it easier to search on, if you wish.

This will include all named branches in the repo. Mercurial does not have something like dangling blobs afaik.

The simple solution would be to use a ItemListener. When the state changes, you would simply check the currently selected item and set the text accordingly

A better solution would be to create a custom object that represents the value to be displayed and the value associated with it...

Updated

Now I no longer have a 10 month chewing on my ankles, I updated the example to use a ListCellRenderer which is a more correct approach then been lazy and overriding toString

import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.DefaultListCellRenderer;
import javax.swing.JComboBox;

import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class TestComboBox06 {

    public static void main(String[] args) {
        new TestComboBox06();
    }

    public TestComboBox06() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException ex) {

                } catch (UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new TestPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }

        });
    }

    public class TestPane extends JPanel {

        private JComboBox cb;
        private JTextField field;

        public TestPane() {
            cb = new JComboBox(new Item[]{
                new Item("Item 1", "20"), 
                new Item("Item 2", "30")});
            cb.setRenderer(new ItemCelLRenderer());
            field = new JTextField(12);

            add(cb);
            add(field);

            cb.setSelectedItem(null);

            cb.addItemListener(new ItemListener() {
                @Override
                public void itemStateChanged(ItemEvent e) {
                    Item item = (Item)cb.getSelectedItem();
                    field.setText(item.getValue());
                }
            });
        }

    }

    public class Item {
        private String value;
        private String text;

        public Item(String text, String value) {
            this.text = text;
            this.value = value;
        }

        public String getText() {
            return text;
        }

        public String getValue() {
            return value;
        }

    }

    public class ItemCelLRenderer extends DefaultListCellRenderer {

        @Override
        public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
            super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus); //To change body of generated methods, choose Tools | Templates.
            if (value instanceof Item) {
                setText(((Item)value).getText());
            }
            return this;
        }

    }

}

In the interface, you specify the property:

public interface IResourcePolicy
{
   string Version { get; set; }
}

In the implementing class, you need to implement it:

public class ResourcePolicy : IResourcePolicy
{
   public string Version { get; set; }
}

This looks similar, but it is something completely different. In the interface, there is no code. You just specify that there is a property with a getter and a setter, whatever they will do.

In the class, you actually implement them. The shortest way to do this is using this { get; set; } syntax. The compiler will create a field and generate the getter and setter implementation for it.

You can use a binding adapter(Kotlin) to achieve this. Create a binding adapter class named ChangeShapeColor like below

@BindingAdapter("shapeColor")

// Method to load shape and set its color 

fun loadShape(textView: TextView, color: String) {
// first get the drawable that you created for the shape 
val mDrawable = ContextCompat.getDrawable(textView.context, 
R.drawable.language_image_bg)
val  shape =   mDrawable as (GradientDrawable)
// use parse color method to parse #34444 to the int 
shape.setColor(Color.parseColor(color))
 }

Create a drawable shape in res/drawable folder. I have created a circle

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="#anyColorCode"/>

<size
    android:width="@dimen/dp_16"
    android:height="@dimen/dp_16"/>
</shape>

Finally refer it to your view

  <TextView>
   .........
  app:shapeColor="@{modelName.colorString}"
 </Textview>

There is no functions in c#. There is methods (typical method:public void UpdateLeaveStatus(EmployeeLeave objUpdateLeaveStatus)) link to msdn and functors - variable of type Func<>

How about this pseudocode:

After a player puts down a piece at position (x,y):

col=row=diag=rdiag=0
winner=false
for i=1 to n
  if cell[x,i]=player then col++
  if cell[i,y]=player then row++
  if cell[i,i]=player then diag++
  if cell[i,n-i+1]=player then rdiag++
if row=n or col=n or diag=n or rdiag=n then winner=true

I'd use an array of char [n,n], with O,X and space for empty.

1. simple.
2. One loop.
3. Five simple variables: 4 integers and one boolean.
4. Scales to any size of n.
5. Only checks current piece.
6. No magic. :)

Just a small point, I see some of the answers using innerhtml. I have toyed with a similar idea but decided not too, In the latest version react version the same process is now called dangerouslyinnerhtml, as you are giving your client a way into your OS by presenting html in the app. This could lead to various attacks as well as SQL injection attempts

For Java 7 you can use try-with-resource for more compact code:

private static boolean available(int port) {
    try (Socket ignored = new Socket("localhost", port)) {
        return false;
    } catch (IOException ignored) {
        return true;
    }
}

UPDATE:

If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile because I was having issues with it on my server. File put contents works just as well.

<?php
/**
 * 
 * Generate Thumbnail using Imagick class
 *  
 * @param string $img
 * @param string $width
 * @param string $height
 * @param int $quality
 * @return boolean on true
 * @throws Exception
 * @throws ImagickException
 */
function generateThumbnail($img, $width, $height, $quality = 90)
{
    if (is_file($img)) {
        $imagick = new Imagick(realpath($img));
        $imagick->setImageFormat('jpeg');
        $imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
        $imagick->setImageCompressionQuality($quality);
        $imagick->thumbnailImage($width, $height, false, false);
        $filename_no_ext = reset(explode('.', $img));
        if (file_put_contents($filename_no_ext . '_thumb' . '.jpg', $imagick) === false) {
            throw new Exception("Could not put contents.");
        }
        return true;
    }
    else {
        throw new Exception("No valid image provided with {$img}.");
    }
}

// example usage
try {
    generateThumbnail('test.jpg', 100, 50, 65);
}
catch (ImagickException $e) {
    echo $e->getMessage();
}
catch (Exception $e) {
    echo $e->getMessage();
}
?>

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...

function makeThumbnails($updir, $img, $id)
{
    $thumbnail_width = 134;
    $thumbnail_height = 189;
    $thumb_beforeword = "thumb";
    $arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
    $original_width = $arr_image_details[0];
    $original_height = $arr_image_details[1];
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);
    if ($arr_image_details[2] == IMAGETYPE_GIF) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    }
    if ($arr_image_details[2] == IMAGETYPE_JPEG) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    }
    if ($arr_image_details[2] == IMAGETYPE_PNG) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    }
    if ($imgt) {
        $old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
        $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
        imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
        $imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
    }
}

The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.

I was facing a similar problem. The solution that I found out was :

1. Declare an interface in your DialogFragment just like James McCracken has explained above.

2. Implement the interface in your activity (not fragment! That is not a good practice).

3. From the callback method in your activity, call a required public function in your fragment which does the job that you want to do.

Thus, it becomes a two-step process : DialogFragment -> Activity and then Activity -> Fragment

I know this is a different twist on the answer, but isn't this more of a concern for a web server? For example, nginx, could help.

The ngx_http_headers_module module allows adding the “Expires” and “Cache-Control” header fields, and arbitrary fields, to a response header

...

location ~ ^<REGXP MATCHING CORS ROUTES> {
    add_header Access-Control-Allow-Methods POST
    ...
}
...

Adding nginx in front of your go service in production seems wise. It provides a lot more feature for authorizing, logging,and modifying requests. Also, it gives the ability to control who has access to your service and not only that but one can specify different behavior for specific locations in your app, as demonstrated above.

I could go on about why to use a web server with your go api, but I think that's a topic for another discussion.

Found a very easy way to do this.

Open http://phpfiddle.org/

Paste following php script in box. In php script set API_ACCESS_KEY, set device ids separated by coma.

Press F9 or click Run.

Have fun ;)

<?php


// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );


$registrationIds = array("YOUR DEVICE IDS WILL GO HERE" );

// prep the bundle
$msg = array
(
    'message'       => 'here is a message. message',
    'title'         => 'This is a title. title',
    'subtitle'      => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1
);

$fields = array
(
    'registration_ids'  => $registrationIds,
    'data'              => $msg
);

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );

echo $result;
?>

For FCM, google url would be: https://fcm.googleapis.com/fcm/send

For FCM v1 google url would be: https://fcm.googleapis.com/v1/projects/YOUR_GOOGLE_CONSOLE_PROJECT_ID/messages:send

Note: While creating API Access Key on google developer console, you have to use 0.0.0.0/0 as ip address. (For testing purpose).

In case of receiving invalid Registration response from GCM server, please cross check the validity of your device token. You may check the validity of your device token using following url:

https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=YOUR_DEVICE_TOKEN

Some response codes:

Following is the description of some response codes you may receive from server.

{ "message_id": "XXXX" } - success
{ "message_id": "XXXX", "registration_id": "XXXX" } - success, device registration id has been changed mainly due to app re-install
{ "error": "Unavailable" } - Server not available, resend the message
{ "error": "InvalidRegistration" } - Invalid device registration Id 
{ "error": "NotRegistered"} - Application was uninstalled from the device

You can also rest your string and work with it like an array of elements using

• Array.prototype.filter()

const mainStr = 'str1,str2,str3,str4';_x000D_
const commas = [...mainStr].filter(l => l === ',').length;_x000D_
_x000D_
console.log(commas);

Or

• Array.prototype.reduce()

const mainStr = 'str1,str2,str3,str4';_x000D_
const commas = [...mainStr].reduce((a, c) => c === ',' ? ++a : a, 0);_x000D_

I ran in this problem with OpenVPN working as well and I've found a solution where you should NOT stop/start OpenVPN server.

Idea that You should specify what exactly subnet you want to use. In docker-compose.yml write:

networks:
  default:
    driver: bridge
    ipam:
      config:
        - subnet: 172.16.57.0/24

That's it. Now, default network will be used and if your VPN did not assign you something from 172.16.57.* subnet, you're fine.

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

By Installing Maven you can not expect the settings.xml in your .m2 folder(If may be hidden folder, to unhide just press Ctrl+h). You need to place the file explicitly at that location. After placing the file maven plugin for eclipse will start using that file too.

To multiply a column of numbers with a constant(same number), I have done like this.

Let C2 to C12 be different numbers which need to be multiplied by a single number (constant). Then type the numbers from C2 to C12.

In D2 type 1 (unity) and in E2 type formula =PRODUCT(C2:C12,CONSTANT). SELECT RIGHT ICON TO APPLY. NOW DRAG E2 THROUGH E12. YOU HAVE DONE IT.

C       D       E=PRODUCT(C2:C12,20)

What is the other application you are trying to suppress the visibility of? Have you investigated other ways of achieving your desired effect? Please do so before subjecting your users to such rogue behaviour as you are describing: what you are trying to do sound rather like what certain naughty sites do with browser windows...

At least try to adhere to the rule of Least Surprise. Users expect to be able to determine the z-order of most applications themselves. You don't know what is most important to them, so if you change anything, you should focus on pushing the other application behind everything rather than promoting your own.

This is of course trickier, since Windows doesn't have a particularly sophisticated window manager. Two approaches suggest themselves:

1. enumerating top-level windows and checking which process they belong to, dropping their z-order if so. (I'm not sure if there are framework methods for these WinAPI functions.)
2. Fiddling with child process permissions to prevent it from accessing the desktop... but I wouldn't try this until the othe approach failed, as the child process might end up in a zombie state while requiring user interaction.

Which SDKs? If you mean the SDK for Cocoa development, you can check in /Developer/SDKs/ to see which ones you have installed.

If you're looking for the Java SDK version, then open up /Applications/Utilities/Java Preferences. The versions of Java that you have installed are listed there.

On Mac OS X 10.6, though, the only Java version is 1.6.

C++11 brought us lambdas, which can be incredibly useful in this situation:

#define MACRO(X,Y)                              \
    [&](x_, y_) {                               \
        cout << "1st arg is:" << x_ << endl;    \
        cout << "2nd arg is:" << y_ << endl;    \
        cout << "Sum is:" << (x_ + y_) << endl; \
    }((X), (Y))

You keep the generative power of macros, but have a comfy scope from which you can return whatever you want (including void). Additionally, the issue of evaluating macro parameters multiple times is avoided.

gcc -dumpversion

-dumpversion Print the compiler version (for example, 3.0) — and don't do anything else.

The same works for following compilers/aliases:

cc -dumpversion
g++ -dumpversion
clang -dumpversion
tcc -dumpversion

Be careful with automate parsing the GCC output:

• Output of --version might be localized (e.g. to Russian, Chinese, etc.)
• GCC might be built with option --with-gcc-major-version-only. And some distros (e.g. Fedora) are already using that
• GCC might be built with option --with-pkgversion. And --version output will contain something like Android (5220042 based on r346389c) clang version 8.0.7 (it's real version string)

From the standard

7.5.2 Element identifiers: the id and class attributes

Attribute definitions

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

class = cdata-list [CS]
This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Yes, just put a space between them.

The problem with every other answer in this thread is that none of them properly parse all special cases of the strings within the enum.

The biggest special case character that was throwing me for a loop was single quotes, as they are encoded themselves as 2 single quotes together! So, for example, an enum with the value 'a' is encoded as enum('''a'''). Horrible, right?

Well, the solution is to use MySQL to parse the data for you!

Since everyone else is using PHP in this thread, that is what I will use. Following is the full code. I will explain it after. The parameter $FullEnumString will hold the entire enum string, extracted from whatever method you want to use from all the other answers. RunQuery() and FetchRow() (non associative) are stand ins for your favorite DB access methods.

function GetDataFromEnum($FullEnumString)
{
    if(!preg_match('/^enum\((.*)\)$/iD', $FullEnumString, $Matches))
        return null;
    return FetchRow(RunQuery('SELECT '.$Matches[1]));
}

preg_match('/^enum\((.*)\)$/iD', $FullEnumString, $Matches) confirms that the enum value matches what we expect, which is to say, "enum(".$STUFF.")" (with nothing before or after). If the preg_match fails, NULL is returned.

This preg_match also stores the list of strings, escaped in weird SQL syntax, in $Matches[1]. So next, we want to be able to get the real data out of that. So you just run "SELECT ".$Matches[1], and you have a full list of the strings in your first record!

So just pull out that record with a FetchRow(RunQuery(...)) and you’re done.

If you wanted to do this entire thing in SQL, you could use the following

SET @TableName='your_table_name', @ColName='your_col_name';
SET @Q=(SELECT CONCAT('SELECT ', (SELECT SUBSTR(COLUMN_TYPE, 6, LENGTH(COLUMN_TYPE)-6) FROM information_schema.COLUMNS WHERE TABLE_NAME=@TableName AND COLUMN_NAME=@ColName)));
PREPARE stmt FROM @Q;
EXECUTE stmt;

P.S. To preempt anyone from saying something about it, no, I do not believe this method can lead to SQL injection.

sys.maxsize is not the actually the maximum integer value which is supported. You can double maxsize and multiply it by itself and it stays a valid and correct value.

However, if you try sys.maxsize ** sys.maxsize, it will hang your machine for a significant amount of time. As many have pointed out, the byte and bit size does not seem to be relevant because it practically doesn't exist. I guess python just happily expands it's integers when it needs more memory space. So in general there is no limit.

Now, if you're talking about packing or storing integers in a safe way where they can later be retrieved with integrity then of course that is relevant. I'm really not sure about packing but I know python's pickle module handles those things well. String representations obviously have no practical limit.

So really, the bottom line is: what is your applications limit? What does it require for numeric data? Use that limit instead of python's fairly nonexistent integer limit.

If you are using twitter Bootstrap add the class text-center to your code.

Building on Jeff Atwood's answer above here it is with GROUP BY and a correlated subquery to get the median for each group.

SELECT TestID, 
(
 (SELECT MAX(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts WHERE TestID = Posts_parent.TestID ORDER BY Score) AS BottomHalf)
 +
 (SELECT MIN(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts WHERE TestID = Posts_parent.TestID ORDER BY Score DESC) AS TopHalf)
) / 2 AS MedianScore,
AVG(Score) AS AvgScore, MIN(Score) AS MinScore, MAX(Score) AS MaxScore
FROM Posts_parent
GROUP BY Posts_parent.TestID

What's going on? Python modules can be part written in C or C++ (typically for speed). If you try to install such a package with Pip (or setup.py), it has to compile that C/C++ from source. Out the box, Pip will brazenly assume you the compiler Microsoft Visual C++ installed. If you don't have it, you'll see this cryptic error message "Error: Unable to find vcvarsall.bat".

The prescribed solution is to install a C/C++ compiler, either Microsoft Visual C++, or MinGW (an open-source project). However, installing and configuring either is prohibitively difficult. (Edit 2014: Microsoft have published a special C++ compiler for Python 2.7)

The easiest solution is to use Christoph Gohlke's Windows installers (.msi) for popular Python packages. He builds installers for Python 2.x and 3.x, 32 bit and 64 bit. You can download them from http://www.lfd.uci.edu/~gohlke/pythonlibs/

If you too think "Error: Unable to find vcvarsall.bat" is a ludicrously cryptic and unhelpful message, then please comment on the bug at http://bugs.python.org/issue2943 to replace it with a more helpful and user-friendly message.

For comparison, Ruby ships with a package manager Gem and offers a quasi-official C/C++ compiler, DevKit. If you try to install a package without it, you see this helpful friendly useful message:

Please update your PATH to include build tools or download the DevKit from http://rubyinstaller.org/downloads and follow the instructions at http://github.com/oneclick/rubyinstaller/wiki/Development-Kit

md5 = hashlib.md5(source).hexdigest() # returns a str
print(md5) # a02506b31c1cd46c2e0b6380fb94eb3d

If you need byte type output, use digest() instead of hexdigest().

The solution that work for me is the following:

If this happens sporadically then my guess is that it has something to do with the timer.

I'm guessing (and this is only a guess since I have no access to your code) that the timer is firing while the form is being closed. The dbiSchedule object has been disposed but the timer somehow still manages to try to call it. This shouldn't happen, because if the timer has a reference to the schedule object then the garbage collector should see this and not dispose of it.

This leads me to ask: are you calling Dispose() on the schedule object manually? If so, are you doing that before disposing of the timer? Be sure that you release all references to the schedule object before Disposing it (i.e. dispose of the timer beforehand).

Now I realize that a few months have passed between the time you posted this and when I am answering, so hopefully, you have resolved this issue. I'm writing this for the benefit of others who may come along later with a similar issue.

Hope this helps.

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

I ran into this today, with a position: fixed modal that I was reusing. I couldn't keep it display: none and then animate it, as it just jumped into appearance, and and z-index (negative values, etc) did weird things as well.

I was also using a height: 0 to height: 100%, but it only worked when the modal appeared. This is the same as if you used left: -100% or something.

Then it struck me that there was a simple answer. Et voila:

First, your hidden modal. Notice the height is 0, and check out the height declaration in transitions... it has a 500ms, which is longer than my opacity transition. Remember, this affects the out-going fade-out transition: returning the modal to its default state.

#modal-overlay {
    background: #999;
    background: rgba(33,33,33,.2);
    display: block;
    overflow: hidden;
    height: 0;
    width: 100%;
    position: fixed;
    top: 0;
    left: 0;
    opacity: 0;
    z-index: 1;
    -webkit-transition: height 0s 500ms, opacity 300ms ease-in-out;
       -moz-transition: height 0s 500ms, opacity 300ms ease-in-out;
            -ms-transition: height 0s 500ms, opacity 300ms ease-in-out;
         -o-transition: height 0s 500ms, opacity 300ms ease-in-out;
        transition: height 0s 500ms, opacity 300ms ease-in-out;
}

Second, your visible modal. Say you're setting a .modal-active to the body. Now the height is 100%, and my transition has also changed. I want the height to be instantly changed, and the opacity to take 300ms.

.modal-active #modal-overlay {
    height: 100%;
    opacity: 1;
    z-index: 90000;
    -webkit-transition: height 0s, opacity 300ms ease-in-out;
       -moz-transition: height 0s, opacity 300ms ease-in-out;
        -ms-transition: height 0s, opacity 300ms ease-in-out;
         -o-transition: height 0s, opacity 300ms ease-in-out;
            transition: height 0s, opacity 300ms ease-in-out;
}

That's it, it works like a charm.

.NET has some handy utility methods for this sort of thing in System.Array:

PS> $a = 'a','b','c'
PS> [array]::IndexOf($a, 'b')
1
PS> [array]::IndexOf($a, 'c')
2

Good points on the above approach in the comments. Besides "just" finding an index of an item in an array, given the context of the problem, this is probably more suitable:

$letters = { 'A', 'B', 'C' }
$letters | % {$i=0} {"Value:$_ Index:$i"; $i++}

Foreach (%) can have a Begin sciptblock that executes once. We set an index variable there and then we can reference it in the process scripblock where it gets incremented before exiting the scriptblock.

If you don't need any special processing, this should do what you're looking for

$lines = file($filename, FILE_IGNORE_NEW_LINES);

Well, this is simple. The above for loops are semantically equivalent to

int i = 0;
while(i < 5) {
    printf("%d", i);
    i++;
}

and

int i = 0;
while(i < 5) {
    printf("%d", i);
    ++i;
}

Note that the lines i++; and ++i; have the same semantics FROM THE PERSPECTIVE OF THIS BLOCK OF CODE. They both have the same effect on the value of i (increment it by one) and therefore have the same effect on the behavior of these loops.

Note that there would be a difference if the loop was rewritten as

int i = 0;
int j = i;
while(j < 5) {
    printf("%d", i);
    j = ++i;
}

int i = 0;
int j = i;
while(j < 5) {
    printf("%d", i);
    j = i++;
}

This is because in first block of code j sees the value of i after the increment (i is incremented first, or pre-incremented, hence the name) and in the second block of code j sees the value of i before the increment.

The discussion I had with Asaph may be unclear to follow as we went back and forth quite a bit.

I thought that I might clarify the upshot of our discourse for others who might face similar situations in the future to benefit from:

ENUM-type columns are very difficult beasts to manipulate. I wanted to add two countries (Malaysia & Sweden) to the existing set of countries in my ENUM.

It seems that MySQL 5.1 (which is what I am running) can only update the ENUM by redefining the existing set in addition to what I want:

This did not work:

ALTER TABLE carmake CHANGE country country ENUM('Sweden','Malaysia') DEFAULT NULL;

The reason was that the MySQL statement was replacing the existing ENUM with another containing the entries 'Malaysia' and 'Sweden' only. MySQL threw up an error because the carmake table already had values like 'England' and 'USA' which were not part of the new ENUM's definition.

Surprisingly, the following did not work either:

ALTER TABLE carmake CHANGE country country ENUM('Australia','England','USA'...'Sweden','Malaysia') DEFAULT NULL;

It turns out that even the order of elements of the existing ENUM needs to be preserved while adding new members to it. So if my existing ENUM looks something like ENUM('England','USA'), then my new ENUM has to be defined as ENUM('England','USA','Sweden','Malaysia') and not ENUM('USA','England','Sweden','Malaysia'). This problem only becomes manifest when there are records in the existing table that use 'USA' or 'England' values.

BOTTOM LINE:

Only use ENUMs when you do not expect your set of members to change once defined. Otherwise, lookup tables are much easier to update and modify.

I'm always running tests against an in-memory DB (HSQLDB or Derby) for these reasons:

• It makes you think which data to keep in your test DB and why. Just hauling your production DB into a test system translates to "I have no idea what I'm doing or why and if something breaks, it wasn't me!!" ;)
• It makes sure the database can be recreated with little effort in a new place (for example when we need to replicate a bug from production)
• It helps enormously with the quality of the DDL files.

The in-memory DB is loaded with fresh data once the tests start and after most tests, I invoke ROLLBACK to keep it stable. ALWAYS keep the data in the test DB stable! If the data changes all the time, you can't test.

The data is loaded from SQL, a template DB or a dump/backup. I prefer dumps if they are in a readable format because I can put them in VCS. If that doesn't work, I use a CSV file or XML. If I have to load enormous amounts of data ... I don't. You never have to load enormous amounts of data :) Not for unit tests. Performance tests are another issue and different rules apply.

Yes it s working: remove the path of jdk 9.0 and uninstall this from Cantroll panel instead install jdk 8version and set it's path, it is working easily with netbean 8.2.

Yes, you can safely pass an array as a parameter.

b''.fromhex('7061756c')

use it without delimiter

I ended up crafting a slightly more aggressive solution:

function toCamelCase(str) {
  const [first, ...acc] = str.replace(/[^\w\d]/g, ' ').split(/\s+/);
  return first.toLowerCase() + acc.map(x => x.charAt(0).toUpperCase() 
    + x.slice(1).toLowerCase()).join('');
}

This one, above, will remove all non-alphanumeric characters and lowercase parts of words that would otherwise remain uppercased, e.g.

• Size (comparative) => sizeComparative
• GDP (official exchange rate) => gdpOfficialExchangeRate
• hello => hello

Here's one way:

CString str;
str.Format("%d", 5);

In your case, try _T("%d") or L"%d" rather than "%d"

Follow the below steps in order

• Create a user using the CLI

use admin
db.createUser(
  {
    user: "admin",
    pwd: "admin123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]
  }
)

• Enable authentication, how you do it differs based on your OS, if you are using windows you can simply mongod --auth in case of linux you can edit the /etc/mongod.conf file to add security.authorization : enabled and then restart the mongd service
• To connect via cli mongo -u "admin" -p "admin123" --authenticationDatabase "admin". That's it

You can check out this post to go into more details and to learn connecting to it using mongoose.

$string = 'this is my world, not my world';

echo strrev($result); //output: this is my world, not my farm

For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2 MIME type, only about .woff. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2, then updated .woff.)

Second, and more importantly, I was bundling bootstrap.css along with some other files as "~/bundles/css/site". Meanwhile, my font files were in "~/fonts". bootstrap.css looks for the glyphicon fonts in "../fonts", which translated to "~/bundles/fonts" -- wrong path.

In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss", and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts" for the glyphicon files, which worked. Problem solved.

Before I fixed the second problem above, none of the glyphicon font files were loading. The symptom was that all instances of glyphicon glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.

The new line character is \n. It is used inside a string.

Example:

    print('First line \n Second line') 

where \n is the newline character.

This would yield the result:

First line
 Second line

If you use Python 2, you do not use the parentheses on the print function.

TL; DR: use np.where as it is the fastest option. Your options are np.where, itertools.compress, and list comprehension.

See the detailed comparison below, where it can be seen np.where outperforms both itertools.compress and also list comprehension.

>>> from itertools import compress
>>> import numpy as np
>>> t = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]`
>>> t = 1000*t

• Method 1: Using list comprehension

>>> %timeit [i for i, x in enumerate(t) if x]
457 µs ± 1.5 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

• Method 2: Using itertools.compress

>>> %timeit list(compress(range(len(t)), t))
210 µs ± 704 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each)

• Method 3 (the fastest method): Using numpy.where

>>> %timeit np.where(t)
179 µs ± 593 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

Max;Musterman;2014/01/02

The corresponding domain model in our system might look like this.

private class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public DateTime BirthDate { get; set; }
}

When using TinyCsvParser you have to define the mapping between the columns in the CSV data and the property in you domain model.

private class CsvPersonMapping : CsvMapping<Person>
{

    public CsvPersonMapping()
        : base()
    {
        MapProperty(0, x => x.FirstName);
        MapProperty(1, x => x.LastName);
        MapProperty(2, x => x.BirthDate);
    }
}

And then we can use the mapping to parse the CSV data with a CsvParser.

namespace TinyCsvParser.Test
{
    [TestFixture]
    public class TinyCsvParserTest
    {
        [Test]
        public void TinyCsvTest()
        {
            CsvParserOptions csvParserOptions = new CsvParserOptions(true, new[] { ';' });
            CsvPersonMapping csvMapper = new CsvPersonMapping();
            CsvParser<Person> csvParser = new CsvParser<Person>(csvParserOptions, csvMapper);

            var result = csvParser
                .ReadFromFile(@"persons.csv", Encoding.ASCII)
                .ToList();

            Assert.AreEqual(2, result.Count);

            Assert.IsTrue(result.All(x => x.IsValid));

            Assert.AreEqual("Philipp", result[0].Result.FirstName);
            Assert.AreEqual("Wagner", result[0].Result.LastName);

            Assert.AreEqual(1986, result[0].Result.BirthDate.Year);
            Assert.AreEqual(5, result[0].Result.BirthDate.Month);
            Assert.AreEqual(12, result[0].Result.BirthDate.Day);

            Assert.AreEqual("Max", result[1].Result.FirstName);
            Assert.AreEqual("Mustermann", result[1].Result.LastName);

            Assert.AreEqual(2014, result[1].Result.BirthDate.Year);
            Assert.AreEqual(1, result[1].Result.BirthDate.Month);
            Assert.AreEqual(1, result[1].Result.BirthDate.Day);
        }
    }
}

User Guide

A full User Guide is available at:

• http://bytefish.github.io/TinyCsvParser/

Please see http://java.dzone.com/articles/how-debug-remote-java-applicat to enable the remote debugging. If you are using tomcat to run your application, start tomcat with remote debug parameters or you can start tomcat with JPDA support by using following command.

Windows

<tomcat bin dir>/startup.bat jpda

*nix

<tomcat bin dir>/startup.sh jpda

this will enable remote debugging on port 8000

You turn off pack_propagate by setting pack_propagate(0)

Turning off pack_propagate here basically says don't let the widgets inside the frame control it's size. So you've set it's width and height to be 500. Turning off propagate stills allows it to be this size without the widgets changing the size of the frame to fill their respective width / heights which is what would happen normally

To turn off resizing the root window, you can set root.resizable(0, 0), where resizing is allowed in the x and y directions respectively.

To set a maxsize to window, as noted in the other answer you can set the maxsize attribute or minsize although you could just set the geometry of the root window and then turn off resizing. A bit more flexible imo.

Whenever you set grid or pack on a widget it will return None. So, if you want to be able to keep a reference to the widget object you shouldn't be setting a variabe to a widget where you're calling grid or pack on it. You should instead set the variable to be the widget Widget(master, ....) and then call pack or grid on the widget instead.

import tkinter as tk

def startgame():

    pass

mw = tk.Tk()

#If you have a large number of widgets, like it looks like you will for your
#game you can specify the attributes for all widgets simply like this.
mw.option_add("*Button.Background", "black")
mw.option_add("*Button.Foreground", "red")

mw.title('The game')
#You can set the geometry attribute to change the root windows size
mw.geometry("500x500") #You want the size of the app to be 500x500
mw.resizable(0, 0) #Don't allow resizing in the x or y direction

back = tk.Frame(master=mw,bg='black')
back.pack_propagate(0) #Don't allow the widgets inside to determine the frame's width / height
back.pack(fill=tk.BOTH, expand=1) #Expand the frame to fill the root window

#Changed variables so you don't have these set to None from .pack()
go = tk.Button(master=back, text='Start Game', command=startgame)
go.pack()
close = tk.Button(master=back, text='Quit', command=mw.destroy)
close.pack()
info = tk.Label(master=back, text='Made by me!', bg='red', fg='black')
info.pack()

mw.mainloop()

It is now 2019 and the TLS v1.3 has been released. According to Cloudflare, the server name indication (SNI aka the hostname) can be encrypted thanks to TLS v1.3. So, I told myself great! Let's see how it looks within the TCP packets of cloudflare.com So, I caught a "client hello" handshake packet from a response of the cloudflare server using Google Chrome as browser & wireshark as packet sniffer. I still can read the hostname in plain text within the Client hello packet as you can see below. It is not encrypted.

So, beware of what you can read because this is still not an anonymous connection. A middleware application between the client and the server could log every domain that are requested by a client.

So, it looks like the encryption of the SNI requires additional implementations to work along with TLSv1.3

UPDATE June 2020: It looks like the Encrypted SNI is initiated by the browser. Cloudflare has a page for you to check if your browser supports Encrypted SNI:

https://www.cloudflare.com/ssl/encrypted-sni/

At this point, I think Google chrome does not support it. You can activate Encrypted SNI in Firefox manually. When I tried it for some reason, it didn't work instantly. I restarted Firefox twice before it worked:

Type: about:config in the URL field.

Check if network.security.esni.enabled is true. Clear your cache / restart

Go to the website, I mentioned before.

As you can see VPN services are still useful today for people who want to ensure that a coffee shop owner does not log the list of websites that people visit.

A very simple approach for the dev who just want to send POST parameters in multipart request.

Make the following changes in class which extends Request.java

First define these constants :

String BOUNDARY = "s2retfgsGSRFsERFGHfgdfgw734yhFHW567TYHSrf4yarg"; //This the boundary which is used by the server to split the post parameters.
String MULTIPART_FORMDATA = "multipart/form-data;boundary=" + BOUNDARY;

Add a helper function to create a post body for you :

private String createPostBody(Map<String, String> params) {
        StringBuilder sbPost = new StringBuilder();
        if (params != null) {
            for (String key : params.keySet()) {
                if (params.get(key) != null) {
                    sbPost.append("\r\n" + "--" + BOUNDARY + "\r\n");
                    sbPost.append("Content-Disposition: form-data; name=\"" + key + "\"" + "\r\n\r\n");
                    sbPost.append(params.get(key).toString());
                }
            }
        }
        return sbPost.toString();
    } 

Override getBody() and getBodyContentType

public String getBodyContentType() {
    return MULTIPART_FORMDATA;
}

public byte[] getBody() throws AuthFailureError {
        return createPostBody(getParams()).getBytes();
}

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.

You can change your Github account name at any time.

To do this, click your profile picture > Settings > Account Settings > Change Username.

Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.

For more information, see the official help page.

And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.

When I was in the UNIX world (using tcsh (sigh...)), I used to have all sorts of "find" aliases/scripts setup for searching for files. I think the default "find" syntax is a little clunky, so I used to have aliases/scripts to pipe "find . -print" into grep, which allows you to use regular expressions for searching:

# finds all .java files starting in current directory
find . -print | grep '\.java'

#finds all .java files whose name contains "Message"
find . -print | grep '.*Message.*\.java'

Of course, the above examples can be done with plain-old find, but if you have a more specific search, grep can help quite a bit. This works pretty well, unless "find . -print" has too many directories to recurse through... then it gets pretty slow. (for example, you wouldn't want to do this starting in root "/")

If you used the auth scaffolding in 5.5 simply direct your href to:

{{ route('logout') }}

There is no need to alter any routes or controllers.

Just need to add font-size: 0; to your element that contains text. This works well.

AJAX does the magic:

$(document).ready(function(

    $.ajax({ url: 'script.php?argument=value&foo=bar' });

));

• Everything that is nil? is blank?
• Everything that is empty? is blank?
• Nothing that is empty? is nil?
• Nothing that is nil? is empty?

tl;dr -- only use blank? & present? unless you want to distinguish between "" and " "

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

See also:

• ViewParam vs @ManagedProperty(value = "#{param.id}")
• Communication in JSF 2.0 - Processing GET request parameters

If you need to use Content-Type=x-www-urlencoded-form then DO NOT use FormDataCollection as parameter: In asp.net Core 2+ FormDataCollection has no default constructors which is required by Formatters. Use IFormCollection instead:

 public IActionResult Search([FromForm]IFormCollection type)
    {
        return Ok();
    }

You can not use DATEDIFF but you can use this (if columns are not date type):

SELECT 
to_date('2008-08-05','YYYY-MM-DD')-to_date('2008-06-05','YYYY-MM-DD') 
AS DiffDate from dual

you can see the sample

http://sqlfiddle.com/#!4/d41d8/34609

Here's a simple way to accomplish this with jQuery that limits it to the appropriate input elements:

//prevent submission of forms when pressing Enter key in a text input
$(document).on('keypress', ':input:not(textarea):not([type=submit])', function (e) {
    if (e.which == 13) e.preventDefault();
});

A couple people here had success by switching the lines around in an XML file.

Here is the code I've been using for programatically importing .cer files into a new KeyStore.

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
//VERY IMPORTANT.  SOME OF THESE EXIST IN MORE THAN ONE PACKAGE!
import java.security.GeneralSecurityException;
import java.security.KeyStore;
import java.security.cert.Certificate;
import java.security.cert.CertificateFactory;

//Put everything after here in your function.
KeyStore trustStore  = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null);//Make an empty store
InputStream fis = /* insert your file path here */;
BufferedInputStream bis = new BufferedInputStream(fis);

CertificateFactory cf = CertificateFactory.getInstance("X.509");

while (bis.available() > 0) {
    Certificate cert = cf.generateCertificate(bis);
    trustStore.setCertificateEntry("fiddler"+bis.available(), cert);
}

This will work

@Cacheable(value="bookCache", key="#checkwarehouse.toString().append(#isbn.toString())")

I've tried all the possibilities. Nothing worked for me except the following. var element = document.querySelectorAll("input[id=btn1]"); element[0].setAttribute("disabled",true);

There are 2 possible solutions that I personally use

1.without using form

 <button type="submit" value={{excel_path}} onclick="location.href='{% url 'downloadexcel' %}'" name='mybtn2'>Download Excel file</button>

2.Using Form

<form action="{% url 'downloadexcel' %}" method="post">
{% csrf_token %}


 <button type="submit" name='mybtn2' value={{excel_path}}>Download results in Excel</button>
 </form>

Where urls.py should have this

path('excel/',views1.downloadexcel,name="downloadexcel"),

In case you're making custom back button basing on UIButton with image of arrow, here is the subclass snippet. Using it you can either create button in code or just assign class in Interface Builder to any UIButton. Back Arrow Image will be added automatically and colored with text color.

@interface UIImage (TintColor)

- (UIImage *)imageWithOverlayColor:(UIColor *)color;

@end


@implementation UIImage (TintColor)

- (UIImage *)imageWithOverlayColor:(UIColor *)color
{
    CGRect rect = CGRectMake(0.0f, 0.0f, self.size.width, self.size.height);

    if (UIGraphicsBeginImageContextWithOptions) {
        CGFloat imageScale = 1.0f;
        if ([self respondsToSelector:@selector(scale)])
            imageScale = self.scale;
        UIGraphicsBeginImageContextWithOptions(self.size, NO, imageScale);
    }
    else {
        UIGraphicsBeginImageContext(self.size);
    }

    [self drawInRect:rect];

    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetBlendMode(context, kCGBlendModeSourceIn);

    CGContextSetFillColorWithColor(context, color.CGColor);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}

@end




#import "iOS7backButton.h"

@implementation iOS7BackButton

-(void)awakeFromNib
{
    [super awakeFromNib];

    BOOL is6=([[[UIDevice currentDevice] systemVersion] floatValue] <7);
    UIImage *backBtnImage = [[UIImage imageNamed:@"backArrow"] imageWithOverlayColor:self.titleLabel.textColor];
    [self setImage:backBtnImage forState:UIControlStateNormal];
    [self setTitleEdgeInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
    [self setImageEdgeInsets:UIEdgeInsetsMake(0, is6?0:-10, 0, 0)];


}


+ (UIButton*) buttonWithTitle:(NSString*)btnTitle andTintColor:(UIColor*)color {
    BOOL is6=([[[UIDevice currentDevice] systemVersion] floatValue] <7);
    UIButton *backBtn=[[UIButton alloc] initWithFrame:CGRectMake(0, 0, 60, 30)];
    UIImage *backBtnImage = [[UIImage imageNamed:@"backArrow"] imageWithOverlayColor:color];
    [backBtn setImage:backBtnImage forState:UIControlStateNormal];
    [backBtn setTitleEdgeInsets:UIEdgeInsetsMake(0, is6?5:-5, 0, 0)];
    [backBtn setImageEdgeInsets:UIEdgeInsetsMake(0, is6?0:-10, 0, 0)];
    [backBtn setTitle:btnTitle forState:UIControlStateNormal];
    [backBtn setTitleColor:color /*#007aff*/ forState:UIControlStateNormal];

    return backBtn;
}

Issue is with remote server, can you login to the remote server and check if "scp" works

probable causes: - scp is not in path - openssh client not installed correctly

ERROR: Linux / Centos:

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

Solution:

• Edit the Jenkins init file by doing

  sudo vi /etc/init.d/jenkins
  

• Add your own Java path, for example:

  /opt/oracle/product/java/jdk1.8.0_45/bin/java
  

• Restart the service:

  sudo service jenkins start
  sudo service jenkins status
  sudo service jenkins stop
  

Try one of this solution

1. In your terminal type find / -name "php.ini"

2. In your terminal type php -i | grep php.ini . It should show the file path as Configuration File (php.ini) Path => /etc

3. If you can access one your php files , open it in a editor (notepad) and insert below code after <?php in a new line phpinfo(); This will tell you the php.ini location
4. You can also talk to php in interactive mode. Just type php -a in the terminal and type phpinfo(); after php initiated.

You can use Chr(13). Then just wrap the whole thing in Chr(34). Chr(34) is double quotes.

• VB.Net Example:
• TheContactInfo = ""
• TheContactInfo = Trim(TheEmail) & chr(13)
• TheContactInfo = TheContactInfo & Trim(ThePhone) & chr(13)
• TheContactInfo = Chr(34) & TheContactInfo & Chr(34)

</Configuration>

TimeBasedTriggeringPolicy

interval (integer) - How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours. The default value is 1.

modulate (boolean) - Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc.

A new log file will be created daily with previous day automatically renamed to:

cucumber_yyyy-MM-dd.log

In a Maven project, you would put the log4j2.xml in src/main/resources or src/test/resources.

Given your specifications (plus additional info in the comments),

• You have a numeric ID column (integer numbers) with only few (or moderately few) gaps.
• Obviously no or few write operations.
• Your ID column has to be indexed! A primary key serves nicely.

The query below does not need a sequential scan of the big table, only an index scan.

First, get estimates for the main query:

SELECT count(*) AS ct              -- optional
     , min(id)  AS min_id
     , max(id)  AS max_id
     , max(id) - min(id) AS id_span
FROM   big;

The only possibly expensive part is the count(*) (for huge tables). Given above specifications, you don't need it. An estimate will do just fine, available at almost no cost (detailed explanation here):

SELECT reltuples AS ct FROM pg_class WHERE oid = 'schema_name.big'::regclass;

As long as ct isn't much smaller than id_span, the query will outperform other approaches.

WITH params AS (
    SELECT 1       AS min_id           -- minimum id <= current min id
         , 5100000 AS id_span          -- rounded up. (max_id - min_id + buffer)
    )
SELECT *
FROM  (
    SELECT p.min_id + trunc(random() * p.id_span)::integer AS id
    FROM   params p
          ,generate_series(1, 1100) g  -- 1000 + buffer
    GROUP  BY 1                        -- trim duplicates
    ) r
JOIN   big USING (id)
LIMIT  1000;                           -- trim surplus

• Generate random numbers in the id space. You have "few gaps", so add 10 % (enough to easily cover the blanks) to the number of rows to retrieve.

• Each id can be picked multiple times by chance (though very unlikely with a big id space), so group the generated numbers (or use DISTINCT).

• Join the ids to the big table. This should be very fast with the index in place.

• Finally trim surplus ids that have not been eaten by dupes and gaps. Every row has a completely equal chance to be picked.

Short version

You can simplify this query. The CTE in the query above is just for educational purposes:

SELECT *
FROM  (
    SELECT DISTINCT 1 + trunc(random() * 5100000)::integer AS id
    FROM   generate_series(1, 1100) g
    ) r
JOIN   big USING (id)
LIMIT  1000;

Refine with rCTE

Especially if you are not so sure about gaps and estimates.

WITH RECURSIVE random_pick AS (
   SELECT *
   FROM  (
      SELECT 1 + trunc(random() * 5100000)::int AS id
      FROM   generate_series(1, 1030)  -- 1000 + few percent - adapt to your needs
      LIMIT  1030                      -- hint for query planner
      ) r
   JOIN   big b USING (id)             -- eliminate miss

   UNION                               -- eliminate dupe
   SELECT b.*
   FROM  (
      SELECT 1 + trunc(random() * 5100000)::int AS id
      FROM   random_pick r             -- plus 3 percent - adapt to your needs
      LIMIT  999                       -- less than 1000, hint for query planner
      ) r
   JOIN   big b USING (id)             -- eliminate miss
   )
SELECT *
FROM   random_pick
LIMIT  1000;  -- actual limit

We can work with a smaller surplus in the base query. If there are too many gaps so we don't find enough rows in the first iteration, the rCTE continues to iterate with the recursive term. We still need relatively few gaps in the ID space or the recursion may run dry before the limit is reached - or we have to start with a large enough buffer which defies the purpose of optimizing performance.

Duplicates are eliminated by the UNION in the rCTE.

The outer LIMIT makes the CTE stop as soon as we have enough rows.

This query is carefully drafted to use the available index, generate actually random rows and not stop until we fulfill the limit (unless the recursion runs dry). There are a number of pitfalls here if you are going to rewrite it.

Wrap into function

For repeated use with varying parameters:

CREATE OR REPLACE FUNCTION f_random_sample(_limit int = 1000, _gaps real = 1.03)
  RETURNS SETOF big AS
$func$
DECLARE
   _surplus  int := _limit * _gaps;
   _estimate int := (           -- get current estimate from system
      SELECT c.reltuples * _gaps
      FROM   pg_class c
      WHERE  c.oid = 'big'::regclass);
BEGIN

   RETURN QUERY
   WITH RECURSIVE random_pick AS (
      SELECT *
      FROM  (
         SELECT 1 + trunc(random() * _estimate)::int
         FROM   generate_series(1, _surplus) g
         LIMIT  _surplus           -- hint for query planner
         ) r (id)
      JOIN   big USING (id)        -- eliminate misses

      UNION                        -- eliminate dupes
      SELECT *
      FROM  (
         SELECT 1 + trunc(random() * _estimate)::int
         FROM   random_pick        -- just to make it recursive
         LIMIT  _limit             -- hint for query planner
         ) r (id)
      JOIN   big USING (id)        -- eliminate misses
   )
   SELECT *
   FROM   random_pick
   LIMIT  _limit;
END
$func$  LANGUAGE plpgsql VOLATILE ROWS 1000;

Call:

SELECT * FROM f_random_sample();
SELECT * FROM f_random_sample(500, 1.05);

You could even make this generic to work for any table: Take the name of the PK column and the table as polymorphic type and use EXECUTE ... But that's beyond the scope of this question. See:

• Refactor a PL/pgSQL function to return the output of various SELECT queries

Possible alternative

IF your requirements allow identical sets for repeated calls (and we are talking about repeated calls) I would consider a materialized view. Execute above query once and write the result to a table. Users get a quasi random selection at lightening speed. Refresh your random pick at intervals or events of your choosing.

Postgres 9.5 introduces TABLESAMPLE SYSTEM (n)

Where n is a percentage. The manual:

The BERNOULLI and SYSTEM sampling methods each accept a single argument which is the fraction of the table to sample, expressed as a percentage between 0 and 100. This argument can be any real-valued expression.

Bold emphasis mine. It's very fast, but the result is not exactly random. The manual again:

The SYSTEM method is significantly faster than the BERNOULLI method when small sampling percentages are specified, but it may return a less-random sample of the table as a result of clustering effects.

The number of rows returned can vary wildly. For our example, to get roughly 1000 rows:

SELECT * FROM big TABLESAMPLE SYSTEM ((1000 * 100) / 5100000.0);

Related:

• Fast way to discover the row count of a table in PostgreSQL

Or install the additional module tsm_system_rows to get the number of requested rows exactly (if there are enough) and allow for the more convenient syntax:

SELECT * FROM big TABLESAMPLE SYSTEM_ROWS(1000);

See Evan's answer for details.

But that's still not exactly random.

how i solve it in Eclipse

1. go to the properties of the project

2. go to Java compiler

3. change in the Compiler complicated level to java that my project work with (java 11 in my project) you can see that it your java that you work when the last message disappear

4. Apply

After the last Firefox update we had the same session timeout issue and the following setting helped to resolve it.

We can control it with network.http.response.timeout parameter.

1. Open Firefox and type in ‘about:config’ in the address bar and press Enter.
2. Click on the "I'll be careful, I promise!" button.
3. Type ‘timeout’ in the search box and network.http.response.timeout parameter will be displayed.
4. Double-click on the network.http.response.timeout parameter and enter the time value (it is in seconds) that you don't want your session not to timeout, in the box.

Yep, using the staticmethod decorator

class MyClass(object):
    @staticmethod
    def the_static_method(x):
        print(x)

MyClass.the_static_method(2)  # outputs 2

Note that some code might use the old method of defining a static method, using staticmethod as a function rather than a decorator. This should only be used if you have to support ancient versions of Python (2.2 and 2.3)

class MyClass(object):
    def the_static_method(x):
        print(x)
    the_static_method = staticmethod(the_static_method)

MyClass.the_static_method(2)  # outputs 2

This is entirely identical to the first example (using @staticmethod), just not using the nice decorator syntax

Finally, use staticmethod sparingly! There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer.

The following is verbatim from the documentation::

A static method does not receive an implicit first argument. To declare a static method, use this idiom:

class C:
    @staticmethod
    def f(arg1, arg2, ...): ...

The @staticmethod form is a function decorator – see the description of function definitions in Function definitions for details.

It can be called either on the class (such as C.f()) or on an instance (such as C().f()). The instance is ignored except for its class.

Static methods in Python are similar to those found in Java or C++. For a more advanced concept, see classmethod().

For more information on static methods, consult the documentation on the standard type hierarchy in The standard type hierarchy.

New in version 2.2.

Changed in version 2.4: Function decorator syntax added.

You can certainly validate the file for a particular charset by decoding it with a CharsetDecoder and watching out for "malformed-input" or "unmappable-character" errors. Of course, this only tells you if a charset is wrong; it doesn't tell you if it is correct. For that, you need a basis of comparison to evaluate the decoded results, e.g. do you know beforehand if the characters are restricted to some subset, or whether the text adheres to some strict format? The bottom line is that charset detection is guesswork without any guarantees.

Update April 10, 2016

Flexboxes should now be used to vertically (or even horizontally) align items.

body {
    height: 150px;
    border: 5px solid cyan; 
    font-size: 50px;
    
    display: flex;
    align-items: center; /* Vertical center alignment */
    justify-content: center; /* Horizontal center alignment */
}

Middle

A good guide to flexbox can be read on CSS Tricks. Thanks Ben (from comments) for pointing it out. I didn't have time to update.

A good guy named Mahendra posted a very working solution here.

The following class should make the element horizontally and vertically centered to its parent.

.absolute-center {

    /* Internet Explorer 10 */
    display: -ms-flexbox;
    -ms-flex-pack: center;
    -ms-flex-align: center;

    /* Firefox */
    display: -moz-box;
    -moz-box-pack: center;
    -moz-box-align: center;

    /* Safari, Opera, and Chrome */
    display: -webkit-box;
    -webkit-box-pack: center;
    -webkit-box-align: center;

    /* W3C */
    display: box;
    box-pack: center;
    box-align: center;
}

Instead of dealing with SSH keys, you can also try Heroku's new beta HTTP Git support. It just uses your API token and runs on port 443, so no SSH keys or port 22 to mess with.

To use HTTP Git, first make sure Toolbelt is updated and that your credentials are current:

$ heroku update
$ heroku login

(this is important because Heroku HTTP Git authenticates in a slightly different way than the rest of Toolbelt)

During the beta, you get HTTP by passing the --http-git flag to the relevant heroku apps:create, heroku git:clone and heroku git:remote commands. To create a new app and have it be configured with a HTTP Git remote, run this:

$ heroku apps:create --http-git

To change an existing app from SSH to HTTP Git, simply run this command from the app’s directory on your machine:

$ heroku git:remote --http-git
Git remote heroku updated

Check out the Dev Center documentation for details on how set up HTTP Git for Heroku.

No one probably really wants to remove row one. So if you are looking for something meaningful, that is conditional selection

#remove rows that have long length and "0" value for vector E

>> setNew<-set[!(set$length=="long" & set$E==0),]

You should have a look at Boost.Python. Here is the short introduction taken from their website:

The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).

Not a Javascript way to answer this but if you use CloudFlare you can write page rules that redirect the user much faster to HTTPS and it's free. Looks like this in CloudFlare's Page Rules:

Java code for start service:

Start service from Activity:

startService(new Intent(MyActivity.this, MyService.class));

Start service from Fragment:

getActivity().startService(new Intent(getActivity(), MyService.class));

MyService.java:

import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;

public class MyService extends Service {

    private static String TAG = "MyService";
    private Handler handler;
    private Runnable runnable;
    private final int runTime = 5000;

    @Override
    public void onCreate() {
        super.onCreate();
        Log.i(TAG, "onCreate");

        handler = new Handler();
        runnable = new Runnable() {
            @Override
            public void run() {

                handler.postDelayed(runnable, runTime);
            }
        };
        handler.post(runnable);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onDestroy() {
        if (handler != null) {
            handler.removeCallbacks(runnable);
        }
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return START_STICKY;
    }

    @SuppressWarnings("deprecation")
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.i(TAG, "onStart");
    }

}

Define this Service into Project's Manifest File:

Add below tag in Manifest file:

<service android:enabled="true" android:name="com.my.packagename.MyService" />

Done

In JBoss EAP 6.4, right click on the server and open launch configuration under VM argument you will find

{-Dprogram.name=JBossTools: jboss-eap" -server -Xms1024m -Xmx1024m -XX:MaxPermSize=256m}

update it to

{-Dprogram.name=JBossTools: JBoss 6.4" -server -Xms512m -Xmx512m}

this will solve your problem.

I also encountered the same problem, my problem has been resolved. The solution is:

According to error information being given, to find the corresponding jar in maven repository and deleted. Then executed mvn install command after deleting.

Edit your style.xml with:

<style name="AppTheme" parent="Base.V21.Theme.AppCompat.Light.Dialog">

As long as you have initialized moment-timezone with the data for the zones you want, your code works as expected.

You are correctly converting the moment to the time zone, which is reflected in the second line of output from momentObj.format().

Switching to UTC doesn't just drop the offset, it changes back to the UTC time zone. If you're going to do that, you don't need the original .tz() call at all. You could just do moment.utc().

Perhaps you are just trying to change the output format string? If so, just specify the parameters you want to the format method:

momentObj.format("YYYY-MM-DD HH:mm:ss")

Regarding the last to lines of your code - when you go back to a Date object using toDate(), you are giving up the behavior of moment.js and going back to JavaScript's behavior. A JavaScript Date object will always be printed in the local time zone of the computer it's running on. There's nothing moment.js can do about that.

A couple of other little things:

• While the moment constructor can take a Date, it is usually best to not use one. For "now", don't use moment(new Date()). Instead, just use moment(). Both will work but it's unnecessarily redundant. If you are parsing from a string, pass that string directly into moment. Don't try to parse it to a Date first. You will find moment's parser to be much more reliable.

• Time Zones like MST7MDT are there for backwards compatibility reasons. They stem from POSIX style time zones, and only a few of them are in the TZDB data. Unless absolutely necessary, you should use a key such as America/Denver.

This is how I am comparing 2 dates, now() and a date from the table

@if (\Carbon\Carbon::now()->lte($item->client->event_date_from))
    .....
    .....
@endif

Should work just right. I have used the comparison functions provided by Carbon.

You can use the function numpy.nonzero(), or the nonzero() method of an array

import numpy as np

A = np.array([[2,4],
          [6,2]])
index= np.nonzero(A>1)
       OR
(A>1).nonzero()

Output:

(array([0, 1]), array([1, 0]))

First array in output depicts the row index and second array depicts the corresponding column index.

why not just

#if RELEASE
#undef DEBUG
#endif
