Here is my sudoku solver in python. It uses simple backtracking algorithm to solve the puzzle. For simplicity no input validations or fancy output is done. It's the bare minimum code which solves the problem.

Algorithm

1. Find all legal values of a given cell
2. For each legal value, Go recursively and try to solve the grid

Solution

It takes 9X9 grid partially filled with numbers. A cell with value 0 indicates that it is not filled.

Code

def findNextCellToFill(grid, i, j):
        for x in range(i,9):
                for y in range(j,9):
                        if grid[x][y] == 0:
                                return x,y
        for x in range(0,9):
                for y in range(0,9):
                        if grid[x][y] == 0:
                                return x,y
        return -1,-1

def isValid(grid, i, j, e):
        rowOk = all([e != grid[i][x] for x in range(9)])
        if rowOk:
                columnOk = all([e != grid[x][j] for x in range(9)])
                if columnOk:
                        # finding the top left x,y co-ordinates of the section containing the i,j cell
                        secTopX, secTopY = 3 *(i//3), 3 *(j//3) #floored quotient should be used here. 
                        for x in range(secTopX, secTopX+3):
                                for y in range(secTopY, secTopY+3):
                                        if grid[x][y] == e:
                                                return False
                        return True
        return False

def solveSudoku(grid, i=0, j=0):
        i,j = findNextCellToFill(grid, i, j)
        if i == -1:
                return True
        for e in range(1,10):
                if isValid(grid,i,j,e):
                        grid[i][j] = e
                        if solveSudoku(grid, i, j):
                                return True
                        # Undo the current cell for backtracking
                        grid[i][j] = 0
        return False

Testing the code

>>> input = [[5,1,7,6,0,0,0,3,4],[2,8,9,0,0,4,0,0,0],[3,4,6,2,0,5,0,9,0],[6,0,2,0,0,0,0,1,0],[0,3,8,0,0,6,0,4,7],[0,0,0,0,0,0,0,0,0],[0,9,0,0,0,0,0,7,8],[7,0,3,4,0,0,5,6,0],[0,0,0,0,0,0,0,0,0]]
>>> solveSudoku(input)
True
>>> input
[[5, 1, 7, 6, 9, 8, 2, 3, 4], [2, 8, 9, 1, 3, 4, 7, 5, 6], [3, 4, 6, 2, 7, 5, 8, 9, 1], [6, 7, 2, 8, 4, 9, 3, 1, 5], [1, 3, 8, 5, 2, 6, 9, 4, 7], [9, 5, 4, 7, 1, 3, 6, 8, 2], [4, 9, 5, 3, 6, 2, 1, 7, 8], [7, 2, 3, 4, 8, 1, 5, 6, 9], [8, 6, 1, 9, 5, 7, 4, 2, 3]]

The above one is very basic backtracking algorithm which is explained at many places. But the most interesting and natural of the sudoku solving strategies I came across is this one from here

Check your connectivity. On my Computer this prints REACHABLE for both IP's:

Sending Ping Request to 127.0.0.1
Host is reachable
Sending Ping Request to 173.194.32.38
Host is reachable

EDIT:

You could try modifying the code to use getByAddress() to obtain the address:

public static void main(String[] args) throws UnknownHostException, IOException {
    InetAddress inet;

    inet = InetAddress.getByAddress(new byte[] { 127, 0, 0, 1 });
    System.out.println("Sending Ping Request to " + inet);
    System.out.println(inet.isReachable(5000) ? "Host is reachable" : "Host is NOT reachable");

    inet = InetAddress.getByAddress(new byte[] { (byte) 173, (byte) 194, 32, 38 });
    System.out.println("Sending Ping Request to " + inet);
    System.out.println(inet.isReachable(5000) ? "Host is reachable" : "Host is NOT reachable");
}

The getByName() methods may attempt some kind of reverse DNS lookup which may not be possible on your machine, getByAddress() might bypass that.

Several interesting answers. Since you just want a border bottom (or top) here are two more. Assuming you want a blue border 3px thick. In the style section you could add

.blueB {background-color:blue; height:3px} or
hr {background-color:blue; color:blue height:3px}

In the table code either

<tr><td colspan='3' class='blueB></td></tr> or
<tr><td colspan='3'><hr></td></tr>

In our instance of this problem, we had pom.xml files where the m2e-specific life cycle mapping configuration

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
                <lifecycleMappingMetadata>
...

did not have the <version>1.0.0</version> part. When doing a Maven -> Update Project..., this causes the reported NullPointerException without a stack trace. When using a fresh Import... -> Existing Maven Projects, the same exception occurred, but with a stack trace that led me to find the above.

(This is with m2e 1.6.1.20150625-2338 in Eclipse Luna Service Release 2 (4.4.2).)

Maybe something like this:

<script>
if(!window.jQuery)
{
   var script = document.createElement('script');
   script.type = "text/javascript";
   script.src = "path/to/jQuery";
   document.getElementsByTagName('head')[0].appendChild(script);
}
</script>

Something like this should do it too :

$last = $wpdb->get_row("SHOW TABLE STATUS LIKE 'table_name'");
$lastid = $last->Auto_increment;

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

Loop through the dictionary to find the index and then remove it.

TL;DR

You can do this by using the --prefix flag and the --global* flag.

pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules
[email protected] /Users/pje/foo/vendor/node_modules/bower

*Even though this is a "global" installation, installed bins won't be accessible through the command line unless ~/foo/vendor/node_modules exists in PATH.

TL;DR

Every configurable attribute of npm can be set in any of six different places. In order of priority:

• Command-Line Flags: --prefix ./vendor/node_modules
• Environment Variables: NPM_CONFIG_PREFIX=./vendor/node_modules
• User Config File: $HOME/.npmrc or userconfig param
• Global Config File: $PREFIX/etc/npmrc or userconfig param
• Built-In Config File: path/to/npm/itself/npmrc
• Default Config: node_modules/npmconf/config-defs.js

By default, locally-installed packages go into ./node_modules. global ones go into the prefix config variable (/usr/local by default).

You can run npm config list to see your current config and npm config edit to change it.

PS

In general, npm's documentation is really helpful. The folders section is a good structural overview of npm and the config section answers this question.

Are you getting errors, or just not sure where to start?

%pylab inline
import pandas as pd
import matplotlib.pyplot as plt

df2 = df.groupby(['Name', 'Abuse/NFF'])['Name'].count().unstack('Abuse/NFF').fillna(0)
df2[['abuse','nff']].plot(kind='bar', stacked=True)

You are trying to insert a record with a value in the foreign key column that doesn't exist in the foreign table.

For example: If you have Books and Authors tables where Books has a foreign key constraint on the Authors table and you try to insert a book record for which there is no author record.

In controller:

function innerItem($scope, $element){
    var jQueryInnerItem = $($element); 
}

This code also working .

#!/bin/bash
FILE=$1
if [ -f $FILE ]; then
 echo "File '$FILE' Exists"
else
 echo "The File '$FILE' Does Not Exist"
fi

Great answers from the guys but I would caution you against always relying on the Session. It is quick and easy to do so, and of course would work but would not be great in all cicrumstances.

For example if you run into a scenario where your hosting doesn't allow session use, or if you are on a web farm, or in the example of a shared SharePoint application.

If you wanted a different solution you could look at using an IOC Container such as Castle Windsor, creating a provider class as a wrapper and then keeping one instance of your class using the per request or session lifestyle depending on your requirements.

The IOC would ensure that the same instance is returned each time.

More complicated yes, if you need a simple solution just use the session.

Here are some implementation examples below out of interest.

Using this method you could create a provider class along the lines of:

public class CustomClassProvider : ICustomClassProvider
{
    public CustomClassProvider(CustomClass customClass)
    { 
        CustomClass = customClass;
    }

    public string CustomClass { get; private set; }
}

And register it something like:

public void Install(IWindsorContainer container, IConfigurationStore store)
{
    container.Register(
            Component.For<ICustomClassProvider>().UsingFactoryMethod(
                () => new CustomClassProvider(new CustomClass())).LifestylePerWebRequest());
    }

It may happen that "this.checked" is always "on". Therefore, I recommend:

$('#checkbox').change(function() {
  if ($(this).is(':checked')) {
    console.log('Checked');
  } else {
    console.log('Unchecked');
  }
});

Recent sdk-manager's download does not contain android-support-v7-appcompat.jar But the following dir contains aar file C:\Users\madan\android-sdks\extras\android\m2repository\com\ android\support\appcompat-v7\24.2.1\appcompat-v7-24.2.1.aar This file can be imported by right-click project, import, select general, select archieve and finally select aar file. Even this does not solve the problem. Later remove 'import android.R' and add 'import android.support.v7.appcompat.*;' Follow this tutorial for other details: http://www.srccodes.com/p/article/22/android-hello-world-example-using-eclipse-ide-and-android-development-tools-adt-plugin

Sorry, the short answer is no. CSS (2.1) will only mark up the elements of a DOM, not their attributes. You'd have to apply a specific class to each input.

Bummer I know, because that would be incredibly useful.

I know you've said you'd prefer CSS over JavaScript, but you should still consider using jQuery. It provides a very clean and elegant way of adding styles to DOM elements based on attributes.

For anyone who wants to work in pixels rather than inches this will work.

Plus the usual you will also need

from matplotlib.transforms import Bbox

Then you can use the following:

my_dpi = 100 # Good default - doesn't really matter

# Size of output in pixels
h = 224
w = 224

fig, ax = plt.subplots(1, figsize=(w/my_dpi, h/my_dpi), dpi=my_dpi)

ax.set_position([0, 0, 1, 1]) # Critical!

# Do some stuff
ax.imshow(img)
ax.imshow(heatmap) # 4-channel RGBA
ax.plot([50, 100, 150], [50, 100, 150], color="red")

ax.axis("off")

fig.savefig("saved_img.png",
            bbox_inches=Bbox([[0, 0], [w/my_dpi, h/my_dpi]]),
            dpi=my_dpi)

In may case, I nedded to copy the gacutil.exe, gacutil.exe.config AND ALSO the gacutlrc.dll (from the 1033 directory)

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

Check the jsfiddle http://jsfiddle.net/CdwB9/3/ and click on delete

function yesnodialog(button1, button2, element){
  var btns = {};
  btns[button1] = function(){ 
      element.parents('li').hide();
      $(this).dialog("close");
  };
  btns[button2] = function(){ 
      // Do nothing
      $(this).dialog("close");
  };
  $("<div></div>").dialog({
    autoOpen: true,
    title: 'Condition',
    modal:true,
    buttons:btns
  });
}
$('.delete').click(function(){
    yesnodialog('Yes', 'No', $(this));
})

Regexp work on the character base, and \d means a single digit 0...9 and not a decimal number.

A regular expression that matches only integers with a sign could be for example

^[-+]?[0-9]+$

meaning

1. ^ - start of string
2. [-+]? - an optional (this is what ? means) minus or plus sign
3. [0-9]+ - one or more digits (the plus means "one or more" and [0-9] is another way to say \d)
4. $ - end of string

Note: having the sign considered part of the number is ok only if you need to parse just the number. For more general parsers handling expressions it's better to leave the sign out of the number: source streams like 3-2 could otherwise end up being parsed as a sequence of two integers instead of an integer, an operator and another integer. My experience is that negative numbers are better handled by constant folding of the unary negation operator at an higher level.

You can use the reinstall module found in npm.

After installing it, you can use the following command:

reinstall

The only difference with manually removing node_modules folder and making npm install is that this command automatically clear npm's cache. So, you can get three steps in one command.

upd: npx reinstall is a way to run this command without globally installing package (only for npm5+)

I would do it this way:

try {
  txtProt = (EditText) findViewById(R.id.Protein); // Same
  p = txtProt.getText().toString(); // Same
  protein = Double.parseDouble(p); // Make use of autoboxing.  It's also easier to read.
} catch (NumberFormatException e) {
  // p did not contain a valid double
}

EDIT: "the program force closes immediately without leaving any info in the logcat"

I don't know bout not leaving information in the logcat output, but a force-close generally means there's an uncaught exception - like a NumberFormatException.

You can use the time() method of datetime objects to get the time of day, which you can use for comparison without taking the date into account:

>>> this_morning = datetime.datetime(2009, 12, 2, 9, 30)
>>> last_night = datetime.datetime(2009, 12, 1, 20, 0)
>>> this_morning.time() < last_night.time()
True

The CSS property display: inline-block was designed to address this need. You can read a bit about it here: http://robertnyman.com/2010/02/24/css-display-inline-block-why-it-rocks-and-why-it-sucks/

Below is an example of its use. The key elements are that the row element has white-space: nowrap and the cell elements have display: inline-block. This example should work on most major browsers; a compatibility table is available here: http://caniuse.com/#feat=inline-block

<html>
<body>
<style>

.row {
    float:left;
    border: 1px solid yellow;
    width: 100%;
    overflow: auto;
    white-space: nowrap;
}

.cell {
    display: inline-block;
    border: 1px solid red;
    width: 200px;
    height: 100px;
}
</style>

<div class="row">
    <div class="cell">a</div>
    <div class="cell">b</div>
    <div class="cell">c</div>
</div>


</body>
</html>

Here is the example:

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

Or if you have longer strings:

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

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

You could do something like this

var option=document.getElementsByName('Gender');

if (!(option[0].checked || option[1].checked)) {
    alert("Please Select Your Gender");
    return false;
}

Just use /\s+/ against '' as a splitter. In this case all "extra" blanks were removed. Usually this particular behaviour is required. So, in you case it will be:

my $line = "file1.gz file1.gz file3.gz";
my @abc = split(/\s+/, $line);

If you aren't dynamically loading scripts or marking them as defer or async, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.

Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.

There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.

When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.

A script tag with async may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async is that it can run anytime and that time is not predictable.

A script tag with defer waits until the entire parser is done and then runs all scripts marked with defer in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer or async.

Here's a quote from that article:

script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.

The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.

A quote from the HTML5 spec:

Then, the first of the following options that describes the situation must be followed:

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:

If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.

Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.

Remove the first element from this list of scripts that will execute in order as soon as possible.

If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.

If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.

Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.

What about Javascript module scripts, type="module"?

Javascript now has support for module loading with syntax like this:

<script type="module">
  import {addTextToBody} from './utils.mjs';

  addTextToBody('Modules are pretty cool.');
</script>

Or, with src attribute:

<script type="module" src="http://somedomain.com/somescript.mjs">
</script>

All scripts with type="module" are automatically given the defer attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.

Module scripts can also be given the async attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async script in any particular order relative to other scripts.

There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.

Use the Microsoft.VisualBasic.FileIO.TextFieldParser class. This will handle parsing a delimited file, TextReader or Stream where some fields are enclosed in quotes and some are not.

For example:

using Microsoft.VisualBasic.FileIO;

string csv = "2,1016,7/31/2008 14:22,Geoff Dalgas,6/5/2011 22:21,http://stackoverflow.com,\"Corvallis, OR\",7679,351,81,b437f461b3fd27387c5d8ab47a293d35,34";

TextFieldParser parser = new TextFieldParser(new StringReader(csv));

// You can also read from a file
// TextFieldParser parser = new TextFieldParser("mycsvfile.csv");

parser.HasFieldsEnclosedInQuotes = true;
parser.SetDelimiters(",");

string[] fields;

while (!parser.EndOfData)
{
    fields = parser.ReadFields();
    foreach (string field in fields)
    {
        Console.WriteLine(field);
    }
} 

parser.Close();

This should result in the following output:

My output:

Shorter and dealing with a column (entire, not just a section of a column):

=COUNTA(A:A)

COUNTA

Beware, a cell containing just a space would be included in the count.

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

Take note of all the MainWindow property settings (WindowStartupLocation, SizeToContent and WindowState) - important for this to work correctly - WindowState for my user case requirement was Maximized

Simply follow three steps;

1. Clear npm cache forcefully:

   npm cache clean -f

2. Install n package globally using npm:

   npm install -g n

3. Install from any of three options:

   a. sudo n stable (get the stable version)

   b. sudo n latest (get the latest version of node)

   c. sudo n x.x.x (get the specific version of node)

I have not used the classes from the Java NIO package, but it seems they might be of some help here. Specifically, java.nio.channels.Channels and java.nio.channels.InterruptibleChannel.

List of all foreign keys referencing a given table in SQL Server :

You can get the referencing table name and column name through following query...

SELECT 
   OBJECT_NAME(f.parent_object_id) TableName,
   COL_NAME(fc.parent_object_id,fc.parent_column_id) ColName
FROM 
   sys.foreign_keys AS f
INNER JOIN 
   sys.foreign_key_columns AS fc 
      ON f.OBJECT_ID = fc.constraint_object_id
INNER JOIN 
   sys.tables t 
      ON t.OBJECT_ID = fc.referenced_object_id
WHERE 
   OBJECT_NAME (f.referenced_object_id) = 'TableName'

And following screenshot for your understanding...

Use predefined git alias, i.e.:

$ git work

Created once by command:

$ git config --global alias.work 'log --pretty=format:"%h%x09%an%x09%ad%x09%s"'

https://git-scm.com/book/tr/v2/Git-Basics-Git-Aliases

Or more colored with graph:

$ git config --global alias.work 'log --pretty=format:"%C(yellow)%h %ar %C(auto)%d %Creset %s , %Cblue%cn" --graph --all'

SELECT latitude, longitude, SQRT(
    POW(69.1 * (latitude - [startlat]), 2) +
    POW(69.1 * ([startlng] - longitude) * COS(latitude / 57.3), 2)) AS distance
FROM TableName HAVING distance < 25 ORDER BY distance;

where [starlat] and [startlng] is the position where to start measuring the distance.

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

It should be located C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log(date stamp)\

Check your tableview frame in storyboard or xib. Mine by default has a y position value, hence the bug

i think this solution is shorter and simpler than older answers. This is Js Code:

const navbar = document.querySelector('.nav-fixed');
window.onscroll = () => {
    if (window.scrollY > 300) {
        navbar.classList.add('nav-active');
    } else {
        navbar.classList.remove('nav-active');
    }
};

And my css:

header.nav-fixed {
    width: 100%;
    position: fixed;
    transition: 0.3s ease-in-out;
}

.nav-active {
    background-color:#fff;
    box-shadow: 5px -1px 12px -5px grey;
}

Cygwin has fully featured fork() on Windows. Thus if using Cygwin is acceptable for you, then the problem is solved in the case performance is not an issue.

Otherwise you can take a look at how Cygwin implements fork(). From a quite old Cygwin's architecture doc:

5.6. Process Creation The fork call in Cygwin is particularly interesting because it does not map well on top of the Win32 API. This makes it very difficult to implement correctly. Currently, the Cygwin fork is a non-copy-on-write implementation similar to what was present in early flavors of UNIX.

The first thing that happens when a parent process forks a child process is that the parent initializes a space in the Cygwin process table for the child. It then creates a suspended child process using the Win32 CreateProcess call. Next, the parent process calls setjmp to save its own context and sets a pointer to this in a Cygwin shared memory area (shared among all Cygwin tasks). It then fills in the child's .data and .bss sections by copying from its own address space into the suspended child's address space. After the child's address space is initialized, the child is run while the parent waits on a mutex. The child discovers it has been forked and longjumps using the saved jump buffer. The child then sets the mutex the parent is waiting on and blocks on another mutex. This is the signal for the parent to copy its stack and heap into the child, after which it releases the mutex the child is waiting on and returns from the fork call. Finally, the child wakes from blocking on the last mutex, recreates any memory-mapped areas passed to it via the shared area, and returns from fork itself.

While we have some ideas as to how to speed up our fork implementation by reducing the number of context switches between the parent and child process, fork will almost certainly always be inefficient under Win32. Fortunately, in most circumstances the spawn family of calls provided by Cygwin can be substituted for a fork/exec pair with only a little effort. These calls map cleanly on top of the Win32 API. As a result, they are much more efficient. Changing the compiler's driver program to call spawn instead of fork was a trivial change and increased compilation speeds by twenty to thirty percent in our tests.

However, spawn and exec present their own set of difficulties. Because there is no way to do an actual exec under Win32, Cygwin has to invent its own Process IDs (PIDs). As a result, when a process performs multiple exec calls, there will be multiple Windows PIDs associated with a single Cygwin PID. In some cases, stubs of each of these Win32 processes may linger, waiting for their exec'd Cygwin process to exit.

Sounds like a lot of work, doesn't it? And yes, it is slooooow.

EDIT: the doc is outdated, please see this excellent answer for an update

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Bootstrap 2.x

You can use the .input-append class like this:

<div class="input-append">
    <input class="span2" type="text">
    <button type="submit" class="btn">
        <i class="icon-search"></i>
    </button>

.gc is a candidate for elimination in future releases - a Sun Engineer once commented that maybe fewer than twenty people in the world actually know how to use .gc() - I did some work last night for a few hours on a central / critical data-structure using SecureRandom generated data, at somewhere just past 40,000 objects the vm would slow down as though it had run out of pointers. Clearly it was choking down on 16-bit pointer tables and exhibited classic "failing machinery" behavior.

I tried -Xms and so on, kept bit twiddling until it would run to about 57,xxx something. Then it would run gc going from say 57,127 to 57,128 after a gc() - at about the pace of code-bloat at camp Easy Money.

Your design needs fundamental re-work, probably a sliding window approach.

get GTK3 version:

dpkg -s libgtk-3-0|grep '^Version'

or just version number

dpkg -s libgtk-3-0|grep '^Version' | cut -d' ' -f2-

textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;

WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this:

using System.Windows.Media;

textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;

This has been asked so many times so that a user with over 1000 points ask for this is some strange
But just to show just another way to do it:

echo "/some/random/file.csv:some string" | awk '{sub(/:.*/,x)}1'
/some/random/file.csv

We never store enumerations as numerical ordinal values anymore; it makes debugging and support way too difficult. We store the actual enumeration value converted to string:

public enum Suit { Spade, Heart, Diamond, Club }

Suit theSuit = Suit.Heart;

szQuery = "INSERT INTO Customers (Name, Suit) " +
          "VALUES ('Ian Boyd', %s)".format(theSuit.name());

and then read back with:

Suit theSuit = Suit.valueOf(reader["Suit"]);

The problem was in the past staring at Enterprise Manager and trying to decipher:

Name                Suit
==================  ==========
Shelby Jackson      2
Ian Boyd            1

verses

Name                Suit
==================  ==========
Shelby Jackson      Diamond
Ian Boyd            Heart

the latter is much easier. The former required getting at the source code and finding the numerical values that were assigned to the enumeration members.

Yes it takes more space, but the enumeration member names are short, and hard drives are cheap, and it is much more worth it to help when you're having a problem.

Additionally, if you use numerical values, you are tied to them. You cannot nicely insert or rearrange the members without having to force the old numerical values. For example, changing the Suit enumeration to:

public enum Suit { Unknown, Heart, Club, Diamond, Spade }

would have to become :

public enum Suit { 
      Unknown = 4,
      Heart = 1,
      Club = 3,
      Diamond = 2,
      Spade = 0 }

in order to maintain the legacy numerical values stored in the database.

How to sort them in the database

The question comes up: lets say i wanted to order the values. Some people may want to sort them by the enum's ordinal value. Of course, ordering the cards by the numerical value of the enumeration is meaningless:

SELECT Suit FROM Cards
ORDER BY SuitID; --where SuitID is integer value(4,1,3,2,0)

Suit
------
Spade
Heart
Diamond
Club
Unknown

That's not the order we want - we want them in enumeration order:

SELECT Suit FROM Cards
ORDER BY CASE SuitID OF
    WHEN 4 THEN 0 --Unknown first
    WHEN 1 THEN 1 --Heart
    WHEN 3 THEN 2 --Club
    WHEN 2 THEN 3 --Diamond
    WHEN 0 THEN 4 --Spade
    ELSE 999 END

The same work that is required if you save integer values is required if you save strings:

SELECT Suit FROM Cards
ORDER BY Suit; --where Suit is an enum name

Suit
-------
Club
Diamond
Heart
Spade
Unknown

But that's not the order we want - we want them in enumeration order:

SELECT Suit FROM Cards
ORDER BY CASE Suit OF
    WHEN 'Unknown' THEN 0
    WHEN 'Heart'   THEN 1
    WHEN 'Club'    THEN 2
    WHEN 'Diamond' THEN 3
    WHEN 'Space'   THEN 4
    ELSE 999 END

My opinion is that this kind of ranking belongs in the user interface. If you are sorting items based on their enumeration value: you're doing something wrong.

But if you wanted to really do that, i would create a Suits dimension table:

| Suit       | SuitID       | Rank          | Color  |
|------------|--------------|---------------|--------|
| Unknown    | 4            | 0             | NULL   |
| Heart      | 1            | 1             | Red    |
| Club       | 3            | 2             | Black  |
| Diamond    | 2            | 3             | Red    |
| Spade      | 0            | 4             | Black  |

This way, when you want to change your cards to use Kissing Kings New Deck Order you can change it for display purposes without throwing away all your data:

| Suit       | SuitID       | Rank          | Color  | CardOrder |
|------------|--------------|---------------|--------|-----------|
| Unknown    | 4            | 0             | NULL   | NULL      |
| Spade      | 0            | 1             | Black  | 1         |
| Diamond    | 2            | 2             | Red    | 1         |
| Club       | 3            | 3             | Black  | -1        |
| Heart      | 1            | 4             | Red    | -1        |

Now we are separating an internal programming detail (enumeration name, enumeration value) with a display setting meant for users:

SELECT Cards.Suit 
FROM Cards
   INNER JOIN Suits ON Cards.Suit = Suits.Suit
ORDER BY Suits.Rank, 
   Card.Rank*Suits.CardOrder

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

As you've discovered above, you can use a combination of window.onbeforeunload and $locationChangeStart to message the user. In addition, you can utilize ngForm.$dirty to only message the user when they have made changes.

I've written an angularjs directive that you can apply to any form that will automatically watch for changes and message the user if they reload the page or navigate away. @see https://github.com/facultymatt/angular-unsavedChanges

Hopefully you find this directive useful!

Hope So this logic will help some one.

I think you're just looking for the overload which takes another Collector to specify what to do with each group... and then Collectors.counting() to do the counting:

import java.util.*;
import java.util.stream.*;

class Test {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();

        list.add("Hello");
        list.add("Hello");
        list.add("World");

        Map<String, Long> counted = list.stream()
            .collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));

        System.out.println(counted);
    }
}

Result:

{Hello=2, World=1}

(There's also the possibility of using groupingByConcurrent for more efficiency. Something to bear in mind for your real code, if it would be safe in your context.)

I have experienced the same issue:

Could not find Developer Disk Image

My Xcode version was 7.0.1, and I updated my iPhone's version to 9.2, and upon using Xcode I ran into this problem.

The solution is pretty simple: Just download the latest version of Xcode 7.2 which was released on 8 Dec, 2015 and install it. Everything works fine for you as it was before.

Note: The actual problem is your Xcode version is not compatible/outdated with the version on your device.

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

You can use the $$ variable.

You can update progress bar only from ProgressChanged or RunWorkerCompleted event handlers as these are synchronized with the UI thread.

The basic idea is. Thread.Sleep just simulates some work here. Replace it with your real routing call.

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.WorkerReportsProgress = true;
}

private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);
    }
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

Open the source tab in 'Developer Tools', click on a line number in a script that is running, this will create a breakpoint and the debugger will break there.

$.ajax({
    dataType: "json",
    type: "POST",
    url: "/Home/AutocompleteID",
    data: data,
    success: function (data) {
        $('#search').html('');
        $('#search').append(data[0].Scheme_Code);
        $('#search').append(data[0].Scheme_Name);
    }
});

This is a way:

1. Using apktool to decode:

    $ apktool d -f {apkfile} -o {output folder}
   

2. Next, using JADX (at github.com/skylot/jadx)

    $ jadx -d {output folder} {apkfile}
   

2 tools extract and decompiler to same output folder.

Here is a working version using v3 of docker-compose.yml. The key is the volumes directive:

mysql:
  image: mysql:5.6
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: root
    MYSQL_USER: theusername
    MYSQL_PASSWORD: thepw
    MYSQL_DATABASE: mydb
  volumes:
    - ./data:/docker-entrypoint-initdb.d

In the directory that I have my docker-compose.yml I have a data dir that contains .sql dump files. This is nice because you can have a .sql dump file per table.

I simply run docker-compose up and I'm good to go. Data automatically persists between stops. If you want remove the data and "suck in" new .sql files run docker-compose down then docker-compose up.

If anyone knows how to get the mysql docker to re-process files in /docker-entrypoint-initdb.d without removing the volume, please leave a comment and I will update this answer.

http://en.wikipedia.org/wiki/Post/Redirect/Get

The most common way to implement this pattern in ASP.Net is to use Response.Redirect(Request.RawUrl)

Consider the differences between Redirect and Transfer. Transfer really isn't telling the browser to forward to a clear form, it's simply returning a cleared form. That may or may not be what you want.

Response.Redirect() does not a waste round trip. If you post to a script that clears the form by Server.Transfer() and reload you will be asked to repost by most browsers since the last action was a HTTP POST. This may cause your users to unintentionally repeat some action, eg. place a second order which will have to be voided later.

A variation when using xpath in Java using count():

int numberofbodies = Integer.parseInt((String) xPath.evaluate("count(/html/body)", doc));
if( numberofbodies==0) {
    // body node missing
}

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

The erase method will be used in two ways:

1. Erasing single element:

   vector.erase( vector.begin() + 3 ); // Deleting the fourth element
   

2. Erasing range of elements:

   vector.erase( vector.begin() + 3, vector.begin() + 5 ); // Deleting from fourth element to sixth element
   

1. mysql -u root -p
2. UPDATE mysql.user SET Password=PASSWORD('mypass') WHERE User='root';
3. Flush the privileges: FLUSH PRIVILEGES;
4. Exit by typing: Exit

5. Edited line in the file config.inc.php with the new root password: $cfg['Servers'][$i]['password'] = 'mypass'

The below simple commands can create a virtual env with version 3.5

apt-get install python3-venv

python3.5 -m venv <your env name>

if you want virtual env version as 3.6

python3.6 -m venv <your env name>

You can use any country code, yes, but that doesn't mean a browser or other software will recognize it or do anything differently because of it. For example, a screen reader might deal with "en-US" and "en-GB" the same if they only support an American accent in English. Another piece of software that has two distinct voices, though, could adjust according to the country code.

You would have to use the JavascriptExecutor class:

WebDriver driver; // Assigned elsewhere
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('//id of element').setAttribute('attr', '10')");

This should work:

if (variable === "") {

}

IMPORTANT:

We have been using the function as provided above by LPG.

However, this contains a bug you might encounter when you start a process that generates a lot of output. Due to this you might end up with a deadlock when using this function. Instead use the adapted version below:

Function Execute-Command ($commandTitle, $commandPath, $commandArguments)
{
  Try {
    $pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = $commandPath
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $commandArguments
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    [pscustomobject]@{
        commandTitle = $commandTitle
        stdout = $p.StandardOutput.ReadToEnd()
        stderr = $p.StandardError.ReadToEnd()
        ExitCode = $p.ExitCode
    }
    $p.WaitForExit()
  }
  Catch {
     exit
  }
}

Further information on this issue can be found at MSDN:

A deadlock condition can result if the parent process calls p.WaitForExit before p.StandardError.ReadToEnd and the child process writes enough text to fill the redirected stream. The parent process would wait indefinitely for the child process to exit. The child process would wait indefinitely for the parent to read from the full StandardError stream.

import datetime

datetime.date.today()  # Returns 2018-01-15

Ar you looking for that:

isEmptyObject(obj) {
  return (obj && (Object.keys(obj).length === 0));
}

(found here)

or that :

function isEmpty(obj) {
    for(var key in obj) {
        if(obj.hasOwnProperty(key))
            return false;
    }
    return true;
}

Use a regular for loop and format the index to be used in the selector.

var array = [];
for (var i = 0; i < 4; i++) {
    var selector = '' + i;
    if (selector.length == 1)
        selector = '0' + selector;
    selector = '#event' + selector;
    array.push($(selector, response).html());
}

Not sure exactly what you try to denote with that syntax, but in almost all RDBMS-es you can use a subquery in the FROM clause (sometimes called an "inline-view"):

SELECT..
FROM (
     SELECT ...
     FROM ...
     ) my_select
WHERE ...

In advanced "enterprise" RDBMS-es (like oracle, SQL Server, postgresql) you can use common table expressions which allows you to refer to a query by name and reuse it even multiple times:

-- Define the CTE expression name and column list.
WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
-- Define the CTE query.
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IS NOT NULL
)
-- Define the outer query referencing the CTE name.
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID
ORDER BY SalesPersonID, SalesYear;

(example from http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx)

You could also try to run the following command:

devenv /ResetSkipPkgs

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

Why don't you try to write a function based on Integer.parseInt(String obj) ? The function could accept as parameter your String object, and then tokenize the String and use Integer.parseInt(String obj) to extract the number from the "lucky" substring...

Javadoc of Integer.parseInt(String obj)

Simply go in Task Manager (windows users) and kill the abd.exe (it is remaining active somehow). After that start Eclipse.

The error

"The connection to adb is down, and a severe error has occured"

happened after installing plugin for Android of Netbeans. After closing Netbeans the process abd.exe remained active. When you want to start again Eclipse ... you will get the error.

You have to manually kill the adb.exe and then start Eclipse.

It worked for me.

I also went through this problem and changed that:

<application  android:debuggable="true" android:icon="@drawable/app_icon" android:label="@string/app_name" android:supportsRtl="true" android:allowBackup="false" android:fullBackupOnly="false" android:theme="@style/UnityThemeSelector">

to

 <application tools:replace="android:allowBackup" android:debuggable="true" android:icon="@drawable/app_icon" android:label="@string/app_name" android:supportsRtl="true" android:allowBackup="false" android:fullBackupOnly="false" android:theme="@style/UnityThemeSelector">

The assignment does not remove the newline characters, it's actually the echo doing this. You need simply put quotes around the string to maintain those newlines:

echo "$testvar"

This will give the result you want. See the following transcript for a demo:

pax> cat num1.txt ; x=$(cat num1.txt)
line 1
line 2

pax> echo $x ; echo '===' ; echo "$x"
line 1 line 2
===
line 1
line 2

The reason why newlines are replaced with spaces is not entirely to do with the echo command, rather it's a combination of things.

When given a command line, bash splits it into words according to the documentation for the IFS variable:

IFS: The Internal Field Separator that is used for word splitting after expansion ... the default value is <space><tab><newline>.

That specifies that, by default, any of those three characters can be used to split your command into individual words. After that, the word separators are gone, all you have left is a list of words.

Combine that with the echo documentation (a bash internal command), and you'll see why the spaces are output:

echo [-neE] [arg ...]: Output the args, separated by spaces, followed by a newline.

When you use echo "$x", it forces the entire x variable to be a single word according to bash, hence it's not split. You can see that with:

pax> function count {
...>    echo $#
...> }
pax> count 1 2 3
3
pax> count a b c d
4
pax> count $x
4
pax> count "$x"
1

Here, the count function simply prints out the number of arguments given. The 1 2 3 and a b c d variants show it in action.

Then we try it with the two variations on the x variable. The one without quotes shows that there are four words, "test", "1", "test" and "2". Adding the quotes makes it one single word "test 1\ntest 2".

If you got any error on your console by saying, “Embedded servlet container failed to start. Port 8080 was already in use.” Then go to application.properties file and add this property “server.port = 8090”.

Actually the default port for spring boot is 8080, if you have something else on that port, the above error will occur. So we are asking spring boot to run on other port by adding “server.port = 8090” in application.properties file.

Sorry, this might be a bit late. But I think I found a better implementation on the go docs.

buf := new(bytes.Buffer)
var num uint16 = 1234
err := binary.Write(buf, binary.LittleEndian, num)
if err != nil {
    fmt.Println("binary.Write failed:", err)
}
fmt.Printf("% x", buf.Bytes())

Use .ashx file type and use the same code

I think the best way to do this with basic R is:

for( i in rownames(df) )
   print(df[i, "column1"])

The advantage over the for( i in 1:nrow(df))-approach is that you do not get into trouble if df is empty and nrow(df)=0.

In my first answer the logic is shown for those who want to go with the logic only.

I think I was not able to make clear to @chalukya3545, that's why I am adding the whole code to let him know the exact flow of the code.

str_replace is considerably faster.

$find_letters = array('a', 'c', 'd');
$string = 'abcdefg';
$match = (str_replace($find_letters, '', $string) != $string);

Use .mp3 audio/mpeg, that's the one I always used. I guess others are just aliases.

  ...(false) && {nonprop: "foo"},_x000D_
  ...({}) && {tricky: "hello"},_x000D_

Concerning the (somewhat off topic I know but since it was brought up earlier) XNA vs OpenGL choice, it might be beneficial in several cases to go with OpenGL instead of XNA (and in other XNA instead of OpenGL...).

If you are going to run the applications on Linux or Mac using Mono, it might be a good choice to go with OpenGL. Also, which isn't so widely known I think, if you have customers that are going to run your applications in a Citrix environment, then DirectX/Direct3D/XNA won't be as economical a choice as OpenGL. The reason for this is that OpenGL applications can be co-hosted on a lesser number of servers (due to performance issues a single server cannot host an infinite number of application instances) than DirectX/XNA applications which demands dedicated virtual servers to run in hardware accelerated mode. Other requirements exists like supported graphics cards etc but I will keep to the XNA vs OpenGL issue. As an IT Architect, Software developer etc this will have to be considered before choosing between OpenGL and DirectX/XNA...

A side note is that WebGL is based on OpenGL ES3 afaik...

As a further note, these are not the only considerations, but they might make the choice easier for some...

<script type="text/javascript">
function showDiv(toggle){
document.getElementById(toggle).style.display = 'block';

<div id="toggle" style="display:none">Hello</div>

You can also add linker flags to a specific target using the LINK_FLAGS property:

set_property(TARGET ${target} APPEND_STRING PROPERTY LINK_FLAGS " ${flag}")

If you want to propagate this change to other targets, you can create a dummy target to link to.

Converting the date without specifying the current format can bring this error to you easily.

Here is an example:

sdate <- "2015.10.10"

Convert without specifying the Format:

date <- as.Date(sdate4) # ==> This will generate the same error"""Error in charToDate(x): character string is not in a standard unambiguous format""".

Convert with specified Format:

date <- as.Date(sdate4, format = "%Y.%m.%d") # ==> Error Free Date Conversion.

Not exactly zipping, but you can compact files in Windows with the compact command:

compact /c /s:<directory or file>

And to uncompress:

compact /u /s:<directory or file>

NOTE: These commands only mark/unmark files or directories as compressed in the file system. They do not produces any kind of archive (like zip, 7zip, rar, etc.)

"WARNING: The command completed successfully but no settings of '[user id here]' have been modified."

This warning means the setting was already set like what you want it to be. So it didn't change anything for that object.

As mentioned, sealed is an equivalent of final for methods and classes.

As for the rest, it is complicated.

• For static final fields, static readonly is the closest thing possible. It allows you to initialize the static field in a static constructor, which is fairly similar to static initializer in Java. This applies both to constants (primitives and immutable objects) and constant references to mutable objects.

  The const modifier is fairly similar for constants, but you can't set them in a static constructor.

• On a field that shouldn't be reassigned once it leaves the constructor, readonly can be used. It is not equal though - final requires exactly one assignment even in constructor or initializer.

• There is no C# equivalent for a final local variable that I know of. If you are wondering why would anyone need it: You can declare a variable prior to an if-else, switch-case or so. By declaring it final, you enforce that it is assigned at most once.

  Java local variables in general are required to be assigned at least once before they are read. Unless the branch jumps out before value read, a final variable is assigned exactly once. All of this is checked compile-time. This requires well behaved code with less margin for an error.

Summed up, C# has no direct equivalent of final. While Java lacks some nice features of C#, it is refreshing for me as mostly a Java programmer to see where C# fails to deliver an equivalent.

I have taken Vlad's idea and changed it a little bit. Instead of

grep -rl oldstr path | xargs sed -i 's/oldstr/newstr/g' /dev/null

Which yields

sed: couldn't edit /dev/null: not a regular file

I'm doing in 3 different connections to the remote server

touch deleteme
grep -rl oldstr path | xargs sed -i 's/oldstr/newstr/g' ./deleteme
rm deleteme

Although this is less elegant and requires 2 more connections to the server (maybe there's a way to do it all in one line) it does the job efficiently as well

Could anybody post a working solution for doing this in the terminal?

ANDROID_HOME is usually a directory like .android. Its where things like the Debug Key will be stored.

export ANDROID_HOME=~/.android 

You can automate it for your login. Just add it to your .bash_profile (below is from my OS X 10.8.5 machine):

$ cat ~/.bash_profile
# MacPorts Installer addition on 2012-07-19 at 20:21:05
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

# Android
export ANDROID_NDK_ROOT=/opt/android-ndk-r9
export ANDROID_SDK_ROOT=/opt/android-sdk
export JAVA_HOME=`/usr/libexec/java_home`
export ANDROID_HOME=~/.android

export PATH="$ANDROID_SDK_ROOT/tools/":"$ANDROID_SDK_ROOT/platform-tools/":"$PATH"

According to David Turner on the NDK Mailing List, both ANDROID_NDK_ROOT and ANDROID_SDK_ROOT need to be set because other tools depend on those values (see Recommended NDK Directory?).

After modifying ~/.bash_profile, then perform the following (or logoff and back on):

source ~/.bash_profile

Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.

I too had the same problem.
Mine was a case where i was using a background image which was in drawables.That particular image was of approx 130kB and was used during splash screen and home page in my android app.

Solution - I just shifted that particular image to drawables-xxx folder from drawables and was able free a lot of memory occupied in background and the skipping frames were no longer skipping.

Update Use 'nodp' drawable resource folder for storing background drawables files.
Will a density qualified drawable folder or drawable-nodpi take precedence?

Check out the language reference:

         //todo
     {% endif %}

     //test if variable is not null
     {% if var is not null %}
         //todo
     {% endif %}

You can try adding action="#{yourBean.function1}" on each button (changing of course the method function2, function3, or whatever you need). If that does not work, you can try the same with the onclick event.

Anyway, it would be easier to help you if you tell us what kind of buttons are you trying to use, a4j:commandButton or whatever you are using.

[ -n file.txt ] doesn't check its size, it checks that the string file.txt is non-zero length, so it will always succeed.

If you want to say "size is non-zero", you need [ -s file.txt ].

To get a file's size, you can use wc -c to get the size (file length) in bytes:

file=file.txt
minimumsize=90000
actualsize=$(wc -c <"$file")
if [ $actualsize -ge $minimumsize ]; then
    echo size is over $minimumsize bytes
else
    echo size is under $minimumsize bytes
fi

In this case, it sounds like that's what you want.

But FYI, if you want to know how much disk space the file is using, you could use du -k to get the size (disk space used) in kilobytes:

file=file.txt
minimumsize=90
actualsize=$(du -k "$file" | cut -f 1)
if [ $actualsize -ge $minimumsize ]; then
    echo size is over $minimumsize kilobytes
else
    echo size is under $minimumsize kilobytes
fi

If you need more control over the output format, you can also look at stat. On Linux, you'd start with something like stat -c '%s' file.txt, and on BSD/Mac OS X, something like stat -f '%z' file.txt.

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

There is another much less known solution which has merit in some places. Use the #NULL! error which does not plot and does not create a zero point for the plot.

So your plot column is filled with the following construct. Assume real data in column A and that the plotted version is in column C.

=If(Isnumber(A2),A2,A2 A3)

That space is a little known operator to produce the intersection of the two cell addresses or ranges. If there is no intersection then it produces the message #NULL!

Cells containing #NULL! are skipped for plotting purposes.

Aside (For Microsoft) just need to get the maths equations to ignore such cells somehow?

Just finish it up.

string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";

DataSet ds = GetDataSet(sqlCommand, connectionString);

DataSet GetDataSet(string sqlCommand, string connectionString)
{
    DataSet ds = new DataSet();
    using (SqlCommand cmd = new SqlCommand(
        sqlCommand, new SqlConnection(connectionString)))
    {
        cmd.Connection.Open();
        DataTable table = new DataTable();
        table.Load(cmd.ExecuteReader());
        ds.Tables.Add(table);
    }
    return ds;

Not sure what you call FIFO these days since Queue is FILO, but when I was a student we used the Stack<E> with the simple push, pop, and a peek... It is really that simple, no need for complicating further with Queue and whatever the accepted answer suggests.

For an external (cross-site) solution, you can use: Get contents of a link tag with JavaScript - not CSS

It uses $.ajax() function, so it includes jquery.

One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:

import math
import numpy
import scipy
import sympy

print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False

I just tested the code at the bottom and it prints 16384 twice (I'm on Excel 2010) and the first row gets selected. Your problem seems to be somewhere else.

Have you tried to get rid of the selects:

Sheets("BOM").Rows(copyFromRow).Copy
With Sheets("Proposal")
    .Paste Destination:=.Rows(copyToRow)
    copyToRow = copyToRow + 1
    Application.CutCopyMode = False
    .Rows(copyToRow).Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
End With

Test code to get convinced that the problem does not seem to be what you think it is.

Sub test()

  Dim r
  Dim i As Long

  i = 1

  r = Rows(i & ":" & i)
  Debug.Print UBound(r, 2)
  r = Rows(i)
  Debug.Print UBound(r, 2)
  Rows(i).Select

End Sub

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or 
#cat release_vars.yml >> vars.yml
mvn ....

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

To amend kris' answer, starting with Git 2.20 (Q4 2018), the proper command for git mergetool will be

git config --global merge.guitool kdiff3 

That is because "git mergetool" learned to take the "--[no-]gui" option, just like "git difftool" does.

See commit c217b93, commit 57ba181, commit 063f2bd (24 Oct 2018) by Denton Liu (Denton-L).
^{(Merged by Junio C Hamano -- gitster -- in commit 87c15d1, 30 Oct 2018)}

mergetool: accept -g/--[no-]gui as arguments

In line with how difftool accepts a -g/--[no-]gui option, make mergetool accept the same option in order to use the merge.guitool variable to find the default mergetool instead of merge.tool.

sqrt=x**(1/2) is doing integer division. 1/2 == 0.

So you're computing x^(1/2) in the first instance, x⁽⁰⁾ in the second.

So it's not wrong, it's the right answer to a different question.

What about including the current directory in the search path?

If you want to use jquery in a web application (e.g. React) and jquery is already loaded with <script src="jquery-3.3.1.js"...

On the webpage you can do:

npm install --save-dev @types/query
and the use it with:
let $: JQueryStatic = (window as any)["jQuery"];

so, you don't need to load jquery a second time (with npm install --save jquery) but have all the advantages of Typescript

There is another way of performing the fit, which is by using the 'lmfit' package. It basically uses the cuve_fit but is much better in fitting and offers complex fitting as well. Detailed step by step instructions are given in the below link. http://cars9.uchicago.edu/software/python/lmfit/model.html#model.best_fit

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, _
                                    ByVal e As DataGridViewCellEventArgs) _
                                    Handles DataGridView1.CellClick

Just a comment on this issue. After I installed Visual Studio 2015 RTM all my resharper shortcuts were gone. (I had them working just fine with RC) A few of my colleagues were having the exact same issue with Visual Studio 2012.

I tried all the suggestions in here but none worked. The way I found to solve this was to: go to Tools -> Import and Export Settings , select the "Import selected environment settings" and in my case use the Settings I had from my RC installation (you can see that there are files with parts of a date as the filename like: CurrentSettings-2014-09-22). For my colleagues problem I basically sent them my .vssettings that I had that was working on my local VS2012 installation.

This effectively solved the shortcut problem. Further investigation in my case showed that although I applied the Resharper shortcuts they were never bound to the actual shortcut key thats why resetting stuff never worked.

I started using mocks with EasyMock. Easy enough to understand, but the replay step was kinda annoying. Mockito removes this, also has a cleaner syntax as it looks like readability was one of its primary goals. I cannot stress enough how important this is, since most of developers will spend their time reading and maintaining existing code, not creating it.

Another nice thing is that interfaces and implementation classes are handled in the same way, unlike in EasyMock where still you need to remember (and check) to use an EasyMock Class Extension.

I've taken a quick look at JMockit recently, and while the laundry list of features is pretty comprehensive, I think the price of this is legibility of resulting code, and having to write more.

For me, Mockito hits the sweet spot, being easy to write and read, and dealing with majority of the situations most code will require. Using Mockito with PowerMock would be my choice.

One thing to consider is that the tool you would choose if you were developing by yourself, or in a small tight-knit team, might not be the best to get for a large company with developers of varying skill levels. Readability, ease of use and simplicity would need more consideration in the latter case. No sense in getting the ultimate mocking framework if a lot of people end up not using it or not maintaining the tests.

I was able to get Jenkins to build a tag by setting the Refspec and Branch Specifier as detailed in this blog post.

I also had to set the Repository Name (to "origin" in my case) so that I could reference it in the Refspec (otherwise it would apparently use a randomly generated name).

It seems that you want a list structure with very fast removal and random access by index (not by key) times. An ArrayList gives you the latter and a HashMap or TreeMap give you the former.

There is one structure in Apache Commons Collections that may be what you are looking for, the TreeList. The JavaDoc specifies that it is optimized for quick insertion and removal at any index in the list. If you also need generics though, this will not help you.

The pattern is wrong. You have a 3-letter day abbreviation, so it must be EEE. You have a 3-letter month abbreviation, so it must be MMM. As those day and month abbreviations are locale sensitive, you'd like to explicitly specify the SimpleDateFormat locale to English as well, otherwise it will use the platform default locale which may not be English per se.

public static void main(String[] args) throws Exception {
    String target = "Thu Sep 28 20:29:30 JST 2000";
    DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
    Date result =  df.parse(target);  
    System.out.println(result);
}

This prints here

Thu Sep 28 07:29:30 BOT 2000

which is correct as per my timezone.

I would also reconsider if you wouldn't rather like to use HH instead of kk. Read the javadoc for details about valid patterns.

Static methods are the methods in Java that can be called without creating an object of class. It is belong to the class.

We use static method when we no need to be invoked method using instance.

Why don't you just refactor the default case as a method and call it from both places? This should be more readable and will allow you to change the code later in a more efficient manner.

Without the .pdb files it is virtually imposible to step through the production code; you have to rely on other tools which can be costly and time consuming. I understand you can use tracing or windbg for instance but it really depends on what you want to achieve. In certain scenarios you just want to step through the remote code (no errors or exceptions) using the production data to observe particular behaviour, and this is where .pdb files come handy. Without them running the debugger on that code is impossible.

If local.properties file is missing, just create one in the "project/android" folder with 'sdk.dir=/Users/apple/Library/Android/sdk' and make sure your SDK in on that location.

for creating a file with custom extensions on mac refer the following link

How do I save a TextEdit (mac) file with a custom extension (.sas)?

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

The problem is that you are not specifying the name of the remote: Instead of

git remote add https://github.com/username/project.git

you should use:

git remote add origin https://github.com/username/project.git

you can also use this code

//test" class="btn btn-primary pull-right">

You could call during init or whatever Locale.setDefault() or -Duser.language=, -Duser.country=, and -Duser.variant= at the command line. Here's something on Sun's site.

You can use max-height in an inline style attribute, as below:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

To use scrolling with content that overflows a given max-height, you can alternatively try the following:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>

To restrict the height to a fixed value you can use something like this.

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

Specify the same value for both max-height and min-height (either in pixels or in points – as long as it’s consistent).

You can also put the same styles in css class in a stylesheet (or a style tag as shown below) and then include the same in your tag. See below:

Style Code:

.fixed-panel {
  min-height: 10;
  max-height: 10;
  overflow-y: scroll;
}

Apply Style :

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>

Hope this helps with your need.

No, Java doesn't support user-defined operator overloading. The only aspect of Java which comes close to "custom" operator overloading is the handling of + for strings, which either results in compile-time concatenation of constants or execution-time concatenation using StringBuilder/StringBuffer. You can't define your own operators which act in the same way though.

For a Java-like (and JVM-based) language which does support operator overloading, you could look at Kotlin or Groovy. Alternatively, you might find luck with a Java compiler plugin solution.

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

To summarize the information found after the link: The JVM allocates the amount specified by -Xms but the OS usually does not allocate real pages until they are needed. So the JVM allocates virtual memory as specified by Xms but only allocates physical memory as is needed.

You can see this by using Process Explorer by Sysinternals instead of task manager on windows.

So there is a real difference between using -Xms64M and -Xms512M. But I think the most important difference is the one you already pointed out: the garbage collector will run more often if you really need the 512MB but only started with 64MB.

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

This is the way i calculated the slope: Source: http://classroom.synonym.com/calculate-trendline-2709.html

class Program
    {
        public double CalculateTrendlineSlope(List<Point> graph)
        {
            int n = graph.Count;
            double a = 0;
            double b = 0;
            double bx = 0;
            double by = 0;
            double c = 0;
            double d = 0;
            double slope = 0;

            foreach (Point point in graph)
            {
                a += point.x * point.y;
                bx = point.x;
                by = point.y;
                c += Math.Pow(point.x, 2);
                d += point.x;
            }
            a *= n;
            b = bx * by;
            c *= n;
            d = Math.Pow(d, 2);

            slope = (a - b) / (c - d);
            return slope;
        }
    }

    class Point
    {
        public double x;
        public double y;
    }

Not relevant to the onclick issue, but also related:

For html attributes whose name collide with javascript reserved words, an alternate name is chosen, eg. <div class=''>, but div.className, or <label for='...'>, but label.htmlFor.

In reasonable browsers, this doesn't affect setAttribute. So in gecko and webkit you'd call div.setAttribute('class', 'foo'), but in IE you have to use the javascript property name instead, so div.setAttribute('className', 'foo').

You are catching the error but then you are re throwing it. You should try and handle it more gracefully, otherwise your user is going to see 500, internal server, errors.

You may want to send back a response telling the user what went wrong as well as logging the error on your server.

I am not sure exactly what errors the request might return, you may want to return something like.

router.get("/emailfetch", authCheck, async (req, res) => {
  try {
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
      emailFetch = emailFetch.data
      res.send(emailFetch)
   } catch(error) {
      res.status(error.response.status)
      return res.send(error.message);
    })

})

This code will need to be adapted to match the errors that you get from the axios call.

I have also converted the code to use the try and catch syntax since you are already using async.

The path is in the registry but usually you edit through this interface:

1. Go to Control Panel -> System -> System settings -> Environment Variables.
2. Scroll down in system variables until you find PATH.
3. Click edit and change accordingly.
4. BE SURE to include a semicolon at the end of the previous as that is the delimiter, i.e. c:\path;c:\path2
5. Launch a new console for the settings to take effect.

There are two problems with your xpath - first you need to remove the child selector from after Data like phihag mentioned. Also you forgot to include root in your xpath. Here is what you want to do:

select="/root/DataSet/Data[@Value1='2']/@Value2"

.disabledLink.disabled {pointer-events:none;}

That should do it hope I helped!

Use curly braces around the variable name:

`tail -1 ${filepath}_newstap.sh`

a vue3 replacement of this answer:

// Vue3

const app = Vue.createApp({})
app.config.globalProperties.$hostname = 'http://localhost:3000'


app.component('a-child-component', {
  mounted() {
    console.log(this.$hostname) // 'http://localhost:3000'
  }
})

Put the javascript part and the end right before the closing </body> then it should work.

http://jsfiddle.net/Q3Zy3/1/

  <img onclick="exportToForm('1.6','55','10','50','1');" src="China-Flag-256.png"/>
  <button onclick="exportToForm('1.6','55','10','50','1');" style="background-color: #00FFFF">Export</button>

  <script type="text/javascript">
      function exportToForm(a,b,c,d,e) {
      alert(a + b);
      window.external.values(a.value, b.value, c.value, d.value, e.value);
  }
</script>

This might work for you (GNU sed):

sed '/Here/!d;s//&\n/;s/.*\n//;:a;/String/bb;$!{n;ba};:b;s//\n&/;P;D' file 

This presents each representation of text between two markers (in this instance Here and String) on a newline and preserves newlines within the text.

@media queries serve this purpose. Here's an example:

@media only screen and (max-width: 991px) and (min-width: 769px){
 /* CSS that should be displayed if width is equal to or less than 991px and larger 
  than 768px goes here */
}

@media only screen and (max-width: 991px){
 /* CSS that should be displayed if width is equal to or less than 991px goes here */
}

You can use lookups in Ansible in order to get the contents of a file, e.g.

user_data: "{{ lookup('file', user_data_file) }}"

Caveat: This lookup will work with local files, not remote files.

Here's a complete example from the docs:

- hosts: all
  vars:
     contents: "{{ lookup('file', '/etc/foo.txt') }}"
  tasks:
     - debug: msg="the value of foo.txt is {{ contents }}"

$("#datetimepicker2").datepicker({ 
  dateFormat: "mm/dd/yy", 
  minDate: new Date()
});

I would suggest you have a look at BackgroundWorker. If you have a loop that large in your WinForm it will block and your app will look like it has hanged.

Look at BackgroundWorker.ReportProgress() to see how to report progress back to the UI thread.

For example:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;
    progressBar1.Value = 0;
    backgroundWorker.RunWorkerAsync();
}

private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);
        backgroundWorker.ReportProgress((j * 100) / 100000);
    }
}

private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // TODO: do something with final calculation.
}

Also in addition to above solutions, also check the location where the tnsname ora file exists and compare with the path in the environment variable

You create an empty project in gitlab then on your local terminal follow one of these:

Push an existing folder

cd existing_folder
git init
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git
git add .
git commit -m "Initial commit"
git push -u origin master

Push an existing Git repository

cd existing_repo
git remote rename origin old-origin
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git
git push -u origin --all
git push -u origin --tags

I would change zoom for transform in all cases because, as explained by other answers, they are not equivalent. In my case it was also necessary to apply transform-origin property to place the items where I wanted.

This worked for me in Chome, Safari and Firefox:

transform: scale(0.4);
transform-origin: top left;
-moz-transform: scale(0.4);
-moz-transform-origin: top left;

You do not need to throw a checked exception. This is a bug within the control of the program, so you want to throw an unchecked exception. Use one of the unchecked exceptions already provided by the Java language, such as IllegalArgumentException, IllegalStateException or NullPointerException.

You may also want to get rid of the setter. You've already provided a way to initiate age through the constructor. Does it need to be updated once instantiated? If not, skip the setter. A good rule, do not make things more public than necessary. Start with private or default, and secure your data with final. Now everyone knows that Person has been constructed properly, and is immutable. It can be used with confidence.

Most likely this is what you really need:

class Person { 

  private final int age;   

  Person(int age) {    

    if (age < 0) 
       throw new IllegalArgumentException("age less than zero: " + age); 

    this.age = age;   
  }

  // setter removed

Use something like this in case you also want to output products details per date as JSON and the MySQL version does not support JSON functions.

SELECT `date`,
CONCAT('{',GROUP_CONCAT('{\"id\": \"',`product_id`,'\",\"name\": \"',`product_name`,'\"}'),'}') as `productsJSON`
FROM `buy` group by `date` 
order by `date` DESC

 product_id product_name     date  
|    1     |     azd    | 2011-12-12 |
|    2     |     xyz    | 2011-12-12 |
|    3     |     ase    | 2011-12-11 |
|    4     |     azwed  | 2011-12-11 |
|    5     |     wed    | 2011-12-10 |
|    6     |     cvg    | 2011-12-10 |
|    7     |     cvig   | 2011-12-09 |

RESULT
       date                                productsJSON
2011-12-12T00:00:00Z    {{"id": "1","name": "azd"},{"id": "2","name": "xyz"}}
2011-12-11T00:00:00Z    {{"id": "3","name": "ase"},{"id": "4","name": "azwed"}}
2011-12-10T00:00:00Z    {{"id": "5","name": "wed"},{"id": "6","name": "cvg"}}
2011-12-09T00:00:00Z    {{"id": "7","name": "cvig"}}

Try it out in SQL Fiddle

If you are using a MySQL version that supports JSON functions then the above query could be re-written:

SELECT `date`,JSON_OBJECTAGG(CONCAT('product-',`product_id`),JSON_OBJECT('id', `product_id`, 'name', `product_name`)) as `productsJSON`
FROM `buy` group by `date`
order by `date` DESC;

Try both in DB Fiddle

button {
    background:transparent;
    border:none;
    outline:none;
    display:block;
    height:200px;
    width:200px;
    cursor:pointer;
}

Give the height and width with respect to the image in the background.This removes the borders and color of a button.You might also need to position it absolute so you can correctly place it where you need.I cant help you further without posting you code

To make it truly invisible you have to set outline:none; otherwise there would be a blue outline in some browsers and you have to set display:block if you need to click it and set dimensions to it

I can suggest two options.

1. Within the method, assuming it is looping and not waiting for an external event, add a local field and test the time each time around the loop.

   void method() {
       long endTimeMillis = System.currentTimeMillis() + 10000;
       while (true) {
           // method logic
           if (System.currentTimeMillis() > endTimeMillis) {
               // do some clean-up
               return;
           }
       }
   }
   

2. Run the method in a thread, and have the caller count to 10 seconds.

   Thread thread = new Thread(new Runnable() {
           @Override
           public void run() {
               method();
           }
   });
   thread.start();
   long endTimeMillis = System.currentTimeMillis() + 10000;
   while (thread.isAlive()) {
       if (System.currentTimeMillis() > endTimeMillis) {
           // set an error flag
           break;
       }
       try {
           Thread.sleep(500);
       }
       catch (InterruptedException t) {}
   }
   

The drawback to this approach is that method() cannot return a value directly, it must update an instance field to return its value.

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

If you are using ajax, it is possible to add the options xhrFields: { responseType: 'blob' }:

$.ajax({
  url: 'yourURL',
  type: 'POST',
  data: yourData,
  xhrFields: { responseType: 'blob' },
  success: function (data, textStatus, jqXHR) {

This error could be an indication that variable with the same name has been used in your code earlier, but for other purposes. Possibly, a variable has been given a name that coincides with the existing function used later in the code.

contentType is the type of data you're sending, so application/json; charset=utf-8 is a common one, as is application/x-www-form-urlencoded; charset=UTF-8, which is the default.

dataType is what you're expecting back from the server: json, html, text, etc. jQuery will use this to figure out how to populate the success function's parameter.

If you're posting something like:

{"name":"John Doe"}

and expecting back:

{"success":true}

Then you should have:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "json",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        alert(result.success); // result is an object which is created from the returned JSON
    },
});

If you're expecting the following:

<div>SUCCESS!!!</div>

Then you should do:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "html",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

One more - if you want to post:

name=John&age=34

Then don't stringify the data, and do:

var data = {"name":"John", "age": 34}
$.ajax({
    dataType : "html",
    contentType: "application/x-www-form-urlencoded; charset=UTF-8", // this is the default value, so it's optional
    data : data,
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

It depends a bit on context. Cardinality means the number of something but it gets used in a variety of contexts.

• When you're building a data model, cardinality often refers to the number of rows in table A that relate to table B. That is, are there 1 row in B for every row in A (1:1), are there N rows in B for every row in A (1:N), are there M rows in B for every N rows in A (N:M), etc.
• When you are looking at things like whether it would be more efficient to use a b*-tree index or a bitmap index or how selective a predicate is, cardinality refers to the number of distinct values in a particular column. If you have a PERSON table, for example, GENDER is likely to be a very low cardinality column (there are probably only two values in GENDER) while PERSON_ID is likely to be a very high cardinality column (every row will have a different value).
• When you are looking at query plans, cardinality refers to the number of rows that are expected to be returned from a particular operation.

There are probably other situations where people talk about cardinality using a different context and mean something else.

I have Mojave 10.14.6 and the only thing that did work for me was:

• setting JAVA_HOME to the following:

export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

• source .bash_profile (or wherever you keep your vars, in my case .zshrc)

Hope it helps! You can now type java --version and it should work

My main query looked like this in the model:

@NamedQuery(name = "getAllCentralFinancialAgencyAccountCd", 
    query = "select distinct i from CentralFinancialAgencyAccountCd i")

And I was still not getting what I considered "distinct" results. They were just distinct based on a primary key combination on the table.

So in the DaoImpl I added an one line change and ended up getting the "distinct" return I wanted. An example would be instead of seeing 00 four times I now just see it once. Here is the code I added to the DaoImpl:

@SuppressWarnings("unchecked")
public List<CacheModelBase> getAllCodes() {

    Session session = (Session) entityManager.getDelegate();
    org.hibernate.Query q = session.getNamedQuery("getAllCentralFinancialAgencyAccountCd");
    q.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY); // This is the one line I had to add to make it do a more distinct query.
    List<CacheModelBase> codes;
    codes = q.list();
    return codes;       
}

I hope this helped! Once again, this might only work if you are following coding practices that implement the service, dao, and model type of project.

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

As others have referred, names in Oracle SQL must be less or equal to 30 characters. I would add that this rule applies not only to table names but to field names as well. So there you have it.

Short form:

.zip is an archive format using, usually, the Deflate compression method. The .gz gzip format is for single files, also using the Deflate compression method. Often gzip is used in combination with tar to make a compressed archive format, .tar.gz. The zlib library provides Deflate compression and decompression code for use by zip, gzip, png (which uses the zlib wrapper on deflate data), and many other applications.

Long form:

The ZIP format was developed by Phil Katz as an open format with an open specification, where his implementation, PKZIP, was shareware. It is an archive format that stores files and their directory structure, where each file is individually compressed. The file type is .zip. The files, as well as the directory structure, can optionally be encrypted.

The ZIP format supports several compression methods:

    0 - The file is stored (no compression)
    1 - The file is Shrunk
    2 - The file is Reduced with compression factor 1
    3 - The file is Reduced with compression factor 2
    4 - The file is Reduced with compression factor 3
    5 - The file is Reduced with compression factor 4
    6 - The file is Imploded
    7 - Reserved for Tokenizing compression algorithm
    8 - The file is Deflated
    9 - Enhanced Deflating using Deflate64(tm)
   10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
   11 - Reserved by PKWARE
   12 - File is compressed using BZIP2 algorithm
   13 - Reserved by PKWARE
   14 - LZMA
   15 - Reserved by PKWARE
   16 - IBM z/OS CMPSC Compression
   17 - Reserved by PKWARE
   18 - File is compressed using IBM TERSE (new)
   19 - IBM LZ77 z Architecture 
   20 - deprecated (use method 93 for zstd)
   93 - Zstandard (zstd) Compression 
   94 - MP3 Compression 
   95 - XZ Compression 
   96 - JPEG variant
   97 - WavPack compressed data
   98 - PPMd version I, Rev 1
   99 - AE-x encryption marker (see APPENDIX E)

Methods 1 to 7 are historical and are not in use. Methods 9 through 98 are relatively recent additions and are in varying, small amounts of use. The only method in truly widespread use in the ZIP format is method 8, Deflate, and to some smaller extent method 0, which is no compression at all. Virtually every .zip file that you will come across in the wild will use exclusively methods 8 and 0, likely just method 8. (Method 8 also has a means to effectively store the data with no compression and relatively little expansion, and Method 0 cannot be streamed whereas Method 8 can be.)

The ISO/IEC 21320-1:2015 standard for file containers is a restricted zip format, such as used in Java archive files (.jar), Office Open XML files (Microsoft Office .docx, .xlsx, .pptx), Office Document Format files (.odt, .ods, .odp), and EPUB files (.epub). That standard limits the compression methods to 0 and 8, as well as other constraints such as no encryption or signatures.

Around 1990, the Info-ZIP group wrote portable, free, open-source implementations of zip and unzip utilities, supporting compression with the Deflate format, and decompression of that and the earlier formats. This greatly expanded the use of the .zip format.

In the early '90s, the gzip format was developed as a replacement for the Unix compress utility, derived from the Deflate code in the Info-ZIP utilities. Unix compress was designed to compress a single file or stream, appending a .Z to the file name. compress uses the LZW compression algorithm, which at the time was under patent and its free use was in dispute by the patent holders. Though some specific implementations of Deflate were patented by Phil Katz, the format was not, and so it was possible to write a Deflate implementation that did not infringe on any patents. That implementation has not been so challenged in the last 20+ years. The Unix gzip utility was intended as a drop-in replacement for compress, and in fact is able to decompress compress-compressed data (assuming that you were able to parse that sentence). gzip appends a .gz to the file name. gzip uses the Deflate compressed data format, which compresses quite a bit better than Unix compress, has very fast decompression, and adds a CRC-32 as an integrity check for the data. The header format also permits the storage of more information than the compress format allowed, such as the original file name and the file modification time.

Though compress only compresses a single file, it was common to use the tar utility to create an archive of files, their attributes, and their directory structure into a single .tar file, and to then compress it with compress to make a .tar.Z file. In fact, the tar utility had and still has an option to do the compression at the same time, instead of having to pipe the output of tar to compress. This all carried forward to the gzip format, and tar has an option to compress directly to the .tar.gz format. The tar.gz format compresses better than the .zip approach, since the compression of a .tar can take advantage of redundancy across files, especially many small files. .tar.gz is the most common archive format in use on Unix due to its very high portability, but there are more effective compression methods in use as well, so you will often see .tar.bz2 and .tar.xz archives.

Unlike .tar, .zip has a central directory at the end, which provides a list of the contents. That and the separate compression provides random access to the individual entries in a .zip file. A .tar file would have to be decompressed and scanned from start to end in order to build a directory, which is how a .tar file is listed.

Shortly after the introduction of gzip, around the mid-1990s, the same patent dispute called into question the free use of the .gif image format, very widely used on bulletin boards and the World Wide Web (a new thing at the time). So a small group created the PNG losslessly compressed image format, with file type .png, to replace .gif. That format also uses the Deflate format for compression, which is applied after filters on the image data expose more of the redundancy. In order to promote widespread usage of the PNG format, two free code libraries were created. libpng and zlib. libpng handled all of the features of the PNG format, and zlib provided the compression and decompression code for use by libpng, as well as for other applications. zlib was adapted from the gzip code.

All of the mentioned patents have since expired.

The zlib library supports Deflate compression and decompression, and three kinds of wrapping around the deflate streams. Those are: no wrapping at all ("raw" deflate), zlib wrapping, which is used in the PNG format data blocks, and gzip wrapping, to provide gzip routines for the programmer. The main difference between zlib and gzip wrapping is that the zlib wrapping is more compact, six bytes vs. a minimum of 18 bytes for gzip, and the integrity check, Adler-32, runs faster than the CRC-32 that gzip uses. Raw deflate is used by programs that read and write the .zip format, which is another format that wraps around deflate compressed data.

zlib is now in wide use for data transmission and storage. For example, most HTTP transactions by servers and browsers compress and decompress the data using zlib, specifically HTTP header Content-Encoding: deflate means deflate compression method wrapped inside the zlib data format.

Different implementations of deflate can result in different compressed output for the same input data, as evidenced by the existence of selectable compression levels that allow trading off compression effectiveness for CPU time. zlib and PKZIP are not the only implementations of deflate compression and decompression. Both the 7-Zip archiving utility and Google's zopfli library have the ability to use much more CPU time than zlib in order to squeeze out the last few bits possible when using the deflate format, reducing compressed sizes by a few percent as compared to zlib's highest compression level. The pigz utility, a parallel implementation of gzip, includes the option to use zlib (compression levels 1-9) or zopfli (compression level 11), and somewhat mitigates the time impact of using zopfli by splitting the compression of large files over multiple processors and cores.
