To split a string with a delimiter with GNU sed you say:

sed 's/delimiter/\n/g'     # GNU sed

For example, to split using : as a delimiter:

$ sed 's/:/\n/g' <<< "he:llo:you"
he
llo
you

Or with a non-GNU sed:

$ sed $'s/:/\\\n/g' <<< "he:llo:you"
he
llo
you

In this particular case, you missed the g after the substitution. Hence, it is just done once. See:

$ echo "string1:string2:string3:string4:string5" | sed s/:/\\n/g
string1
string2
string3
string4
string5

g stands for global and means that the substitution has to be done globally, that is, for any occurrence. See that the default is 1 and if you put for example 2, it is done 2 times, etc.

All together, in your case you would need to use:

sed 's/:/\\n/g' ~/Desktop/myfile.txt

Note that you can directly use the sed ... file syntax, instead of unnecessary piping: cat file | sed.

Zach had this one right.. using his method you could also make a seemingly "multi-dimensional" array.. I created a quick example at JSFiddle http://jsfiddle.net/LcnvJ/2/

// array[0][0] will produce brian
// array[0][1] will produce james

// array[1][0] will produce kevin
// array[1][1] will produce haley

var array = [];
    array[0] = "brian,james,doug".split(",");
    array[1] = "kevin,haley,steph".split(",");

VelocityEngine velocityEngin = new VelocityEngine();
velocityEngin.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
velocityEngin.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());

velocityEngin.init();

Template template = velocityEngin.getTemplate("nameOfTheTemplateFile.vtl");

you could use the above code to set the properties for velocity template. You can then give the name of the tempalte file when initializing the Template and it will find if it exists in the classpath.

All the above classes come from package org.apache.velocity*

Microsoft Access and LibreOffice Base can open a spreadsheet as a source and run sql queries on it. That would be the easiest way to run all kinds of queries, and avoid the mess of running macros or writing code.

Excel also has autofilters and data sorting that will accomplish a lot of simple queries like your example. If you need help with those features, Google would be a better source for tutorials than me.

If your JavaScript source is

elem.innerHTML="<img src='smily' alt='It\'s a Smily' style='width:50px'>";

the HTML source will be:

<img src="smiley" alt="It's a Smiley" style="width:50px">

Or for HTML5

<img src=smiley alt="It's a Smiley" style=width:50px>

JavaScript allows arrays like that:

var arr=['this','that'];

But if you stringify it, it will be for compatibility reasons:

JSON=["this","that"]

I'm sure this takes some time.

If you know the aspect ratio for example, if your image is square you can set either the height or the width to fill the container and get the other to be set by the aspectRatio property

Here is the style if you want the height be set automatically:

{
    width: '100%',
    height: undefined,
    aspectRatio: 1,
}

Note: height must be undefined

FWIW,

Poor mans security folder (to protect a public shared folder from little prying eyes ;) )

mkdir -p {0..9}/{0..9}/{0..9}/{0..9}

Now you can put your files in a pin numbered folder. Not exactly waterproof, but it's a barrier for the youngest.

You get this error when you try to run a 32-bit build on your 64-bit Linux.

Also contrast what file had to say on the binary you tried (ie: 32-bit) with what you get for your /bin/gzip:

$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB executable, x64-64, version 1 (SYSV), \
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

which is what I get on Ubuntu 9.10 for amd64 aka x86_64.

Edit: Your expanded post shows that as the readelf output also reflects a 32-bit build.

"py -m pip install requests" works fine with Windows and its up gradation. Just change the path after installing Python 3.4 in the command prompt and type in "py -m pip install requests"command prompt. pip install

This seems related to this: jQuery style not being applied in Safari

The solution suggested in the first response has worked well for me in these scenarios, namely: apply and remove a dummy class to the body after making the styling changes:

$('body').addClass('dummyclass').removeClass('dummyclass');

This forces safari to redraw.

For a shopping cart situation here's what I recommend. I'm gonna break it down into it's simplest form.

Assuming we start with this(a list view with 2 colums, 2 buttons, and a label):

First things first, removing the items, to do that we'll enter our remove button:

private void button2_Click(object sender, EventArgs e)
{
    listView1.Items.Remove(listView1.SelectedItems[0]);
    label1.Text = updateCartTotal().ToString();
}

Now the second line is updating our labels total using the next function i'll post to addup all the total of column 2 in the listview:

private decimal updateCartTotal()
{
    decimal runningTotal = 0;
    foreach(ListViewItem l in listView1.Items)
    {
        runningTotal += Convert.ToDecimal(l.SubItems[1].Text);
    }
    return runningTotal;
}

You don't have to use decimal like I did, you can use float or int if you don't have decimals. So let's break it down. We use a for loop to total all the items in the column 2(SubItems[1].Text). Add that to a decimal we declared prior to the foreach loop to keep a total. If you want to do tax you can do something like:

return runningTotal * 1.15;

or whatever your tax rate is.

Long and short of it, using this function you can retotal your listview by just calling the function. You can change the labels text like I demo'd prior if that's what you're after.

In your Jenkins job configuration, tick the box named "This build is parameterized", click the "Add Parameter" button and select the "String Parameter" drop down value.

Now define your parameter - example:

Now you can use your parameter in your job / build pipeline, example:

Next to trigger the build with own/custom parameter, invoke the following URL (using either POST or GET):

http://JENKINS_SERVER_ADDRESS/job/YOUR_JOB_NAME/buildWithParameters?myparam=myparam_value

I stumbled across this for the same reason as anyone else. But the quoted scripts didn't quite work for me. I've made one that is more a hybrid of those I've seen and it now lives here - https://gitlab.com/inorton/git-size-calc

Here is my combined solution for various PHP versions.

In my company we are working with different servers with various PHP versions, so I had to find solution working for all.

$phpVersion = substr(phpversion(), 0, 3)*1;

if($phpVersion >= 5.4) {
  $encodedValue = json_encode($value, JSON_UNESCAPED_UNICODE);
} else {
  $encodedValue = preg_replace('/\\\\u([a-f0-9]{4})/e', "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($value));
}

Credits should go to Marco Gasi & abu. The solution for PHP >= 5.4 is provided in the json_encode docs.

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

I use both Clang and GCC, I find Clang has some useful warnings, but for my own ray-tracing benchmarks - its consistently 5-15% slower then GCC (take that with grain of salt of course, but attempted to use similar optimization flags for both).

So for now I use Clang static analysis and its warnings with complex macros: (though now GCC's warnings are pretty much as good - gcc4.8 - 4.9).

Some considerations:

• Clang has no OpenMP support, only matters if you take advantage of that but since I do, its a limitation for me. (*****)
• Cross compilation may not be as well supported (FreeBSD 10 for example still use GCC4.x for ARM), gcc-mingw for example is available on Linux... (YMMV).
• Some IDE's don't yet support parsing Clangs output (QtCreator for example *****). EDIT: QtCreator now supports Clang's output
• Some aspects of GCC are better documented and since GCC has been around for longer and is widely used, you might find it easier to get help with warnings / error messages.

***** - these areas are in active development and may soon be supported

I open the project,.csproj, using a notepad and delete that missing file reference.

Your equals2() method always will return the same as equals() !!

Your code with my comments:

public boolean equals2(Object object2) {  // equals2 method
    if(a.equals(object2)) { // if equals() method returns true
        return true; // return true
    }
    else return false; // if equals() method returns false, also return false
}

Install yaml from the PyYAML home pagee: http://www.pyyaml.org/wiki/PyYAML

Select the appropriate version for your OS and Python.

On windows 7, you have to use this command: python -m pip install xxx. All above don't work for me.

I recommend the Boost.Random library, it's super detailed and well-documented, lets you explicitly specify what distribution you want, and in non-cryptographic scenarios can actually outperform a typical C library rand implementation.

A slightly modified version of @sidanmor 's code. The main point is, not every webpage is purely ASCII, user should be able to handle the decoding manually (even encode into base64)

function httpGet(url) {
  return new Promise((resolve, reject) => {
    const http = require('http'),
      https = require('https');

    let client = http;

    if (url.toString().indexOf("https") === 0) {
      client = https;
    }

    client.get(url, (resp) => {
      let chunks = [];

      // A chunk of data has been recieved.
      resp.on('data', (chunk) => {
        chunks.push(chunk);
      });

      // The whole response has been received. Print out the result.
      resp.on('end', () => {
        resolve(Buffer.concat(chunks));
      });

    }).on("error", (err) => {
      reject(err);
    });
  });
}

(async(url) => {
  var buf = await httpGet(url);
  console.log(buf.toString('utf-8'));
})('https://httpbin.org/headers');

I solved this with Access options.

Go to the Office Button --> Access Options --> Trust Center --> Trust Center Settings Button --> Message Bar

In the right hand pane I selected the radio button "Show the message bar in all applications when content has been blocked."

Closed Access, reopened the database and got the warning for blocked content again.

Use This Within button on Click option or your needs:

final ProgressDialog progressDialog;
progressDialog = new ProgressDialog(getApplicationContext());
progressDialog.setMessage("Loading..."); // Setting Message
progressDialog.setTitle("ProgressDialog"); // Setting Title
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); // Progress Dialog Style Spinner
progressDialog.show(); // Display Progress Dialog
progressDialog.setCancelable(false);
new Thread(new Runnable() {
    public void run() {
        try {
            Thread.sleep(5000);
        } catch (Exception e) {
            e.printStackTrace();
        }
        progressDialog.dismiss();
    }
}).start();

I have another example, that I made for my process:

I get an Array with value-Description like this

states = [{
    status: '1',
    desc: '\u2713'
}, {
    status: '2',
    desc: '\u271B'
}]

in my Filters.js:

.filter('getState', function () {
    return function (input, states) {
        //console.log(states);
        for (var i = 0; i < states.length; i++) {
            //console.log(states[i]);
            if (states[i].status == input) {
                return states[i].desc;
            }
        }
        return '\u2718';
    };
})

Then, a test var (controller):

function myCtrl($scope, $filter) {
    // ....
    var resp = $filter('getState')('1', states);
    // ....
}

I think your co-worker is smart and you are also correct.

The useful things I found that putting everything into the headers is that:

1. No need for writing & sync headers and sources.

2. The structure is plain and no circular dependencies force the coder to make a "better" structure.

3. Portable, easy to embedded to a new project.

I do agree with the compiling time problem, but I think we should notice that:

1. The change of source file are very likely to change the header files which leads to the whole project be recompiled again.

2. Compiling speed is much faster than before. And if you have a project to be built with a long time and high frequency, it may indicates that your project design has flaws. Seperate the tasks into different projects and module can avoid this problem.

Lastly I just wanna support your co-worker, just in my personal view.

Set the traditional property to true before making the get call. i.e.:

jQuery.ajaxSettings.traditional = true

$.get('/controller/MyAction', { vals: arrayOfValues }, function (data) {... 

I'm using client.emit('disconnect') + client.removeAllListeners() for connected client for ignore all events after disconnect

Another (and I think better) way to achieve this is to actually intercept the data. limitTo is okay but what if you're limiting to 10 when your array actually contains thousands?

When calling my service I simply did this:

TaskService.getTasks(function(data){
    $scope.tasks = data.slice(0,10);
});

This limits what is sent to the view, so should be much better for performance than doing this on the front-end.

• On the front properties page of the variable script, amend the ReadOnlyVariables (or ReadWriteVariables) property and select the variables you are interested in. This will enable the selected variables within the script task

• Within code you will now have access to read the variable as

  string myString = Variables.MyVariableName.ToString();

Using 2.7:

from functools import partial
from random import randint

for roll in iter(partial(randint, 1, 8), 1):
    print 'you rolled: {}'.format(roll)
print 'oops you rolled a 1!'

you rolled: 7
you rolled: 7
you rolled: 8
you rolled: 6
you rolled: 8
you rolled: 5
oops you rolled a 1!

Then change the "oops" print to a raise SystemExit

I believe the answer above is incorrect, the proper way to initialize with multiple values would be this...

int[] otherList ={1,2,3,4,5};

so the full answer with the proper initialization would look like this

int[] otherList ={1,2,3,4,5};
arList.addAll(Arrays.asList(otherList));

Found a way to do this, simply add a querystring to load your components, like so:

@Component({
  selector: 'some-component',
  templateUrl: `./app/component/stuff/component.html?v=${new Date().getTime()}`,
  styleUrls: [`./app/component/stuff/component.css?v=${new Date().getTime()}`]
})

This should force the client to load the server's copy of the template instead of the browser's. If you would like it to refresh only after a certain period of time you could use this ISOString instead:

new Date().toISOString() //2016-09-24T00:43:21.584Z

And substring some characters so that it will only change after an hour for example:

new Date().toISOString().substr(0,13) //2016-09-24T00

Hope this helps

Per the documentation, scipy.io.wavfile.read(somefile) returns a tuple of two items: the first is the sampling rate in samples per second, the second is a numpy array with all the data read from the file:

from scipy.io import wavfile
samplerate, data = wavfile.read('./output/audio.wav')

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

Both .ics and .vcs files are in ASCII. If you use "Save As" option to save a calendar entry (Appt, Meeting Request/Response/Postpone/Cancel and etc) in both .ics and .vcs format and use vimdiff, you can easily see the difference.

Both .vcs (vCal) and .ics (iCal) belongs to the same VCALENDAR camp, but .vcs file shows "VERSION:1.0" whereas .ics file uses "VERSION:2.0".

The spec for vCalendar v1.0 can be found at http://www.imc.org/pdi/pdiproddev.html. The spec for iCalendar (vCalendar v2.0) is in RFC5545. In general, the newer is better, and that is true for Outlook 2007 and onward, but not for Outlook 2003.

For Outlook 2003, the behavior is peculiar. It can save the same calendar entry in both .ics and .vcs format, but it only read & display .vcs file correctly. It can read .ics file but it omits some fields and does not display it in calendar mode. My guess is that back then Microsoft wanted to provide .ics to be compatible with Mac's iCal but not quite committed to v2.0 yet.

So I would say for Outlook 2003, .vcs is the native format.

The easiest way is probably to use xvfb-run:

DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.0b3.jar

xvfb-run does the whole X authority dance for you, give it a try!

If you are trying to make more than just one folder on the root of the sdcard, ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"

then instead of folder.mkdir() you would use folder.mkdirs()

I've made this mistake in the past & I took forever to figure it out.

Microsoft SQL Server's INTERSECT "returns any distinct values that are returned by both the query on the left and right sides of the INTERSECT operand" This is different from a standard INNER JOIN or WHERE EXISTS query.

SQL Server

CREATE TABLE table_a (
    id INT PRIMARY KEY,
    value VARCHAR(255)
);

CREATE TABLE table_b (
    id INT PRIMARY KEY,
    value VARCHAR(255)
);

INSERT INTO table_a VALUES (1, 'A'), (2, 'B'), (3, 'B');
INSERT INTO table_b VALUES (1, 'B');

SELECT value FROM table_a
INTERSECT
SELECT value FROM table_b

value
-----
B

(1 rows affected)

MySQL

CREATE TABLE `table_a` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `value` varchar(255),
  PRIMARY KEY (`id`)
) ENGINE=InnoDB;

CREATE TABLE `table_b` LIKE `table_a`;

INSERT INTO table_a VALUES (1, 'A'), (2, 'B'), (3, 'B');
INSERT INTO table_b VALUES (1, 'B');

SELECT value FROM table_a
INNER JOIN table_b
USING (value);

+-------+
| value |
+-------+
| B     |
| B     |
+-------+
2 rows in set (0.00 sec)

SELECT value FROM table_a
WHERE (value) IN
(SELECT value FROM table_b);

+-------+
| value |
+-------+
| B     |
| B     |
+-------+

With this particular question, the id column is involved, so duplicate values will not be returned, but for the sake of completeness, here's a MySQL alternative using INNER JOIN and DISTINCT:

SELECT DISTINCT value FROM table_a
INNER JOIN table_b
USING (value);

+-------+
| value |
+-------+
| B     |
+-------+

And another example using WHERE ... IN and DISTINCT:

SELECT DISTINCT value FROM table_a
WHERE (value) IN
(SELECT value FROM table_b);

+-------+
| value |
+-------+
| B     |
+-------+

Just use this constructor of List<T>. It accepts any IEnumerable<T> as an argument.

string[] arr = ...
List<string> list = new List<string>(arr);

Have you looked at the samples provided with EPPlus?

This one shows you how to create a file http://epplus.codeplex.com/wikipage?title=ContentSheetExample

This one shows you how to use it to stream back a file http://epplus.codeplex.com/wikipage?title=WebapplicationExample

This is how we use the package to generate a file.

var newFile = new FileInfo(ExportFileName);
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{                       
    // do work here                            
    xlPackage.Save();
}

Try below one:

svn copy http://svn.example.com/repos/calc/trunk@rev-no 
       http://svn.example.com/repos/calc/branches/my-calc-branch 
  -m "Creating a private branch of /calc/trunk."  --parents

No slash "\" between the svn URLs.

You can use SET ECHO ON in the beginning of your script to achieve that, however, you have to specify your script using @ instead of < (also had to add EXIT at the end):

test.sql

SET ECHO ON

SELECT COUNT(1) FROM dual;

SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

EXIT

terminal

sqlplus hr/oracle@orcl @/tmp/test.sql > /tmp/test.log

test.log

SQL> 
SQL> SELECT COUNT(1) FROM dual;

  COUNT(1)

     1

SQL> 
SQL> SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

  COUNT(1)

Since 2.3 version of Gson library the JsonArray class have a 'set' method.

Here's an simple example:

JsonArray array = new JsonArray();
array.add(new JsonPrimitive("Red"));
array.add(new JsonPrimitive("Green"));
array.add(new JsonPrimitive("Blue"));

array.remove(2);
array.set(0, new JsonPrimitive("Yelow"));

I installed docker from snap repository. So I also had to start from snap (running Ubuntu).

sudo snap start docker

Otherwise you can also install it from their repositories.

1. Open SQL Management Studio
2. Expand your database
3. Expand the "Security" Folder
4. Expand "Users"
5. Right click the user (the one that's trying to perform the query) and select Properties.
6. Select page Membership.

7. Make sure you uncheck

   db_denydatareader

   db_denydatawriter

This should go without saying, but only grant the permissions to what the user needs. An easy lazy fix is to check db_owner like I have, but this is not the best security practice.

A little bit simpler and more effective variation of @yannis solution:

SELECT 
    title,
    description,    
    CHAR_LENGTH(description) - CHAR_LENGTH( REPLACE ( description, 'value', '1234') ) 
        AS `count`    
FROM <table> 

The difference is that I replace the "value" string with a 1-char shorter string ("1234" in this case). This way you don't need to divide and round to get an integer value.

Generalized version (works for every needle string):

SET @needle = 'value';
SELECT 
    description,    
    CHAR_LENGTH(description) - CHAR_LENGTH(REPLACE(description, @needle, SPACE(LENGTH(@needle)-1))) 
        AS `count`    
FROM <table> 

Change your black and white IDs to classes instead (duplicate IDs are invalid), add 2 buttons with the proper IDs, and do this:

var rows = $('table.someclass tr');

$('#showBlackButton').click(function() {
    var black = rows.filter('.black').show();
    rows.not( black ).hide();
});

$('#showWhiteButton').click(function() {
    var white = rows.filter('.white').show();
    rows.not( white ).hide();
});

$('#showAll').click(function() {
    rows.show();
});

<button id="showBlackButton">show black</button>
<button id="showWhiteButton">show white</button>
<button id="showAll">show all</button>

<table class="someclass" border="0" cellpadding="0" cellspacing="0" summary="bla bla bla">
    <caption>bla bla bla</caption>
    <thead>
          <tr class="black">
            ...
          </tr>
    </thead>
    <tbody>
        <tr class="white">
            ...
        </tr>
        <tr class="black">
           ...
        </tr>
    </tbody>
</table>

It uses the filter()^[docs] method to filter the rows with the black or white class (depending on the button).

Then it uses the not()^[docs] method to do the opposite filter, excluding the black or white rows that were previously found.

EDIT: You could also pass a selector to .not() instead of the previously found set. It may perform better that way:

rows.not( `.black` ).hide();

// ...

rows.not( `.white` ).hide();

...or better yet, just keep a cached set of both right from the start:

var rows = $('table.someclass tr');
var black = rows.filter('.black');
var white = rows.filter('.white');

$('#showBlackButton').click(function() {
    black.show();
    white.hide();
});

$('#showWhiteButton').click(function() {
    white.show();
    black.hide();
});

To remove it from all inputs

input {
 outline:none;
}

In case of an associative array or numbered array where you do not want to change the array keys:

$firstItem = array('foo' => 'bar');

$arr = $firstItem + $arr;

array_merge does not work as it always reindexes the array.

Despite onclick Method you can also use formaction as follows:

<button type="submit" id="button1" name="button1" formaction='@Url.Action("Action", "Controller")'>Save</button>

Console Application is an application (.exe), not a Library (.dll). To make a library, create a new project, select "Class Library" in type of project, then copy the logic of your first code into this new project.

Or you can edit the Project Properties and select Class Library instead of Console Application in Output type.

As some code can be "console" dependant, I think first solution is better if you check your logic when you copy it.

You can use requests and beautifulsoup libraries to read data on a website. Just install these two libraries and type the following code.

import requests
import bs4
help(requests)
help(bs4)

You will get all the information you need about the library.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Setting form action after selection of option using JavaScript

<script>
    function onSelectedOption(sel) {
        if ((sel.selectedIndex) == 0) {
            document.getElementById("edit").action =
            "http://www.example.co.uk/index.php";
            document.getElementById("edit").submit();
        }
        else
        {
            document.getElementById("edit").action =
            "http://www.example.co.uk/different.php";
            document.getElementById("edit").submit();
        }
    }
</script>

<form name="edit" id="edit" action="" method="GET">
    <input type="hidden" name="id" value="{ID}" />
</form>

<select name="option" id="option" onchange="onSelectedOption(this);">
    <option name="contactBuyer">Edit item</option>
    <option name="relist">End listing</option>
</select>

Use this code.

driver.FindElement(By.XPath(".//[@id='header']/div/div[3]/div/form/input[1]")).SendKeys("25025");

This is a metadata change only: it is quick.

Handlebars supports {{else if}} blocks as of 3.0.0.

Handlebars v3.0.0 or greater:

{{#if FriendStatus.IsFriend}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else if FriendStatus.FriendRequested}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
{{else}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
{{/if}}

Prior to Handlebars v3.0.0, however, you will have to either define a helper that handles the branching logic or nest if statements manually:

{{#if FriendStatus.IsFriend}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else}}
  {{#if FriendStatus.FriendRequested}}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
  {{else}}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
  {{/if}}
{{/if}}

An sql sum of column_name's unique values and sorted by the frequency:

SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name ORDER BY 2 DESC;

There is no big difference, they basically do the same thing but doing them in different ways, but read on, look at this statement at W3C:

var cars = ["Saab", "Volvo","BMW"];

and

var cars = new Array("Saab", "Volvo", "BMW");

The two examples above do exactly the same. There is no need to use new Array().
For simplicity, readability and execution speed, use the first one (the array literal method).

But at the same time, creating new array using new Array syntax considered as a bad practice:

Avoid new Array()

There is no need to use the JavaScript's built-in array constructor new Array().
Use [] instead.
These two different statements both create a new empty array named points:

var points = new Array();         // Bad
var points = [];                  // Good 

These two different statements both create a new array containing 6 numbers:

var points = new Array(40, 100, 1, 5, 25, 10); // Bad    
var points = [40, 100, 1, 5, 25, 10];          // Good

The new keyword only complicates the code. It can also produce some unexpected results:

var points = new Array(40, 100);  // Creates an array with two elements (40 and 100)

What if I remove one of the elements?

var points = new Array(40);       // Creates an array with 40 undefined elements !!!!!

So basically not considered as the best practice, also there is one minor difference there, you can pass length to new Array(length) like this, which also not a recommended way.

Its must you file dump.sql problem.Use Sequel Pro check your file ecoding.It should be garbage characters in your dump.sql.

len = max(key for (item, key) in list)
newlist = [[] for i in range(len+1)]
for item,key in list:
  newlist[key].append(item)

You can do it in a single list comprehension, perhaps more elegant but O(n**2):

[[item for (item,key) in list if key==i] for i in range(max(key for (item,key) in list)+1)]

While using virtual machines is the best way of testing old IEs, it is possible to bring back old-fashioned F12 tools by editing registry as IE11 overwrites this value when new F12 tool is activated.

Thanks to awesome Dimitri Nickola? for this trick.

This works for me (save as .reg file and run):

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

Installing on a Mac - Sierra - After numerous failed attempts to install and run gulp globally via the command line using several different instructions I found I added this to my path and it worked:

export PATH=/usr/local/Cellar/node/7.6.0/libexec/npm/bin/:$PATH

I got that path from the text output when installing gulp.

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :

strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"

players is a list which needs to be indexed by integers. You seem to be using it like a dictionary. Maybe you could use unpacking -- Something like:

name, score = player

(if the player list is always a constant length).

There's not much more advice we can give you without knowing what query is and how it works.

It's worth pointing out that the entire code you posted doesn't make a whole lot of sense. There's an IndentationError on the second line. Also, your function is looping over some iterable, but unconditionally returning during the first iteration which isn't usually what you actually want to do.

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

For anyone who has this issue with an already running container, and they don't necessarily want to rebuild, the following command connects to a running container with root privileges:

docker exec -ti -u root container_name bash

You can also connect using its ID, rather than its name, by finding it with:

docker ps -l

To save your changes so that they are still there when you next launch the container (or docker-compose cluster):

docker commit container_id image_name

To roll back to a previous image version (warning: this deletes history rather than appends to the end, so to keep a reference to the current image, tag it first using the optional step):

docker history image_name
docker tag latest_image_id my_descriptive_tag_name  # optional
docker tag desired_history_image_id image_name

To start a container that isn't running and connect as root:

docker run -ti -u root --entrypoint=/bin/bash image_id_or_name -s

To copy from a running container:

docker cp <containerId>:/file/path/within/container /host/path/target

To export a copy of the image:

docker save container | gzip > /dir/file.tar.gz

Which you can restore to another Docker install using:

gzcat /dir/file.tar.gz | docker load

It is much quicker but takes more space to not compress, using:

docker save container | dir/file.tar

And:

cat dir/file.tar | docker load

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

I have a C# project (Windows Console Application). I have created a folder named Images inside project. There is one ico file called MyIcon.ico. I accessed MyIcon.ico inside Images folder like below.

this.Icon = new Icon(@"../../Images/MyIcon.ico");

Here´s an alternative with AJAX but no jQuery, just regular JavaScript:

Add this to first/main php page, where you want to call the action from, but change it from a potential a tag (hyperlink) to a button element, so it does not get clicked by any bots or malicious apps (or whatever).

<head>
<script>
  // function invoking ajax with pure javascript, no jquery required.
  function myFunction(value_myfunction) {
    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200) {
        document.getElementById("results").innerHTML += this.responseText; 
        // note '+=', adds result to the existing paragraph, remove the '+' to replace.
      }
    };
    xmlhttp.open("GET", "ajax-php-page.php?sendValue=" + value_myfunction, true);
    xmlhttp.send();
  }

</script>
</head>

<body>

  <?php $sendingValue = "thevalue"; // value to send to ajax php page. ?> 

  <!-- using button instead of hyperlink (a) -->
  <button type="button" onclick="value_myfunction('<?php echo $sendingValue; ?>');">Click to send value</button>

  <h4>Responses from ajax-php-page.php:</h4>
  <p id="results"></p> <!-- the ajax javascript enters returned GET values here -->

</body>

When the button is clicked, onclick uses the the head´s javascript function to send $sendingValue via ajax to another php-page, like many examples before this one. The other page, ajax-php-page.php, checks for the GET value and returns with print_r:

<?php

  $incoming = $_GET['sendValue'];

  if( isset( $incoming ) ) {
    print_r("ajax-php-page.php recieved this: " . "$incoming" . "<br>");
  } else {
    print_r("The request didn´t pass correctly through the GET...");
  }

?>

The response from print_r is then returned and displayed with

document.getElementById("results").innerHTML += this.responseText;

The += populates and adds to existing html elements, removing the + just updates and replaces the existing contents of the html p element "results".

Use string interpolation decimalVar:0.00

This should do the trick:

import pandas as pd
import pymysql
pymysql.install_as_MySQLdb()
from sqlalchemy import create_engine

# Create engine
engine = create_engine('mysql://USER_NAME_HERE:PASS_HERE@HOST_ADRESS_HERE/DB_NAME_HERE')

# Create the connection and close it(whether successed of failed)
with engine.begin() as connection:
  df.to_sql(name='INSERT_TABLE_NAME_HERE/INSERT_NEW_TABLE_NAME', con=connection, if_exists='append', index=False)

    new java.util.Timer().schedule(new TimerTask(){
        @Override
        public void run() {
            System.out.println("Executed...");
           //your code here 
           //1000*5=5000 mlsec. i.e. 5 seconds. u can change accordngly 
        }
    },1000*5,1000*5); 

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

On the solution explorer, right click on the project title and select the 'Properties' on the context menu to open the 'Project Property' form. In the 'Application' tab, on the 'Resources' group box there is a entry field where you can select the icon file you want for your application.

As of Twig 1.5, the correct answer is to use the dump function. It is fully documented in the Twig documentation. Here is the documentation to enable this inside Symfony2.

{{ dump(user) }}

I think that error from Nginx is indicating that the connection was closed by your nodejs server (i.e., "upstream"). How is nodejs configured?

The thing you will need to do here is use a linear gradient as background and animate the background position. In code:

Use a linear gradient (50% red, 50% blue) and tell the browser that background is 2 times larger than the element's width (width:200%, height:100%), then tell it to position the background left.

background: linear-gradient(to right, red 50%, blue 50%);
background-size: 200% 100%;
background-position:left bottom;

On hover, change the background position to right bottom and with transition:all 2s ease;, the position will change gradually (it's nicer with linear tough) background-position:right bottom;

http://jsfiddle.net/75Umu/3/

As for the -vendor-prefix'es, see the comments to your question

extra If you wish to have a "transition" in the colour, you can make it 300% width and make the transition start at 34% (a bit more than 1/3) and end at 65% (a bit less than 2/3).

background: linear-gradient(to right, red 34%, blue 65%);
background-size: 300% 100%;

Demo:

div {
    font: 22px Arial;
    display: inline-block;
    padding: 1em 2em;
    text-align: center;
    color: white;
    background: red; /* default color */

    /* "to left" / "to right" - affects initial color */
    background: linear-gradient(to left, salmon 50%, lightblue 50%) right;
    background-size: 200%;
    transition: .5s ease-out;
}
div:hover {
    background-position: left;
}

<div>Hover me</div>

EDIT: Below was the preferred solution in 2014. Nowadays you should use @include, as mentioned in the other answer.

In Laravel views the dot is used as folder separator. So for example I have this code

return View::make('auth.details', array('id' => $id));

which points to app/views/auth/details.blade.php

And to include a view inside a view you do like this:

file: layout.blade.php

<html>
  <html stuff>
  @yield('content')
</html>

file: hello.blade.php

@extends('layout')

@section('content')
  <html stuff>
@stop

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }

You can check out my project: JavaSysMon on GitHub. It provides process id and a bunch of other stuff (CPU usage, memory usage) cross-platform (presently Windows, Mac OSX, Linux and Solaris)

@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")

Here is another example on how you can loop through a document or an element:

function getNodeList(elem){
var l=new Array(elem),c=1,ret=new Array();
//This first loop will loop until the count var is stable//
for(var r=0;r<c;r++){
    //This loop will loop thru the child element list//
    for(var z=0;z<l[r].childNodes.length;z++){

         //Push the element to the return array.
        ret.push(l[r].childNodes[z]);

        if(l[r].childNodes[z].childNodes[0]){
            l.push(l[r].childNodes[z]);c++;
        }//IF           
    }//FOR
}//FOR
return ret;
}

I don't know anything about EF really, but in LINQ to SQL you usually express a LIKE clause using String.Contains:

where entity.Name.Contains("xyz")

translates to

WHERE Name LIKE '%xyz%'

(Use StartsWith and EndsWith for other behaviour.)

I'm not entirely sure whether that's helpful, because I don't understand what you mean when you say you're trying to implement LIKE. If I've misunderstood completely, let me know and I'll delete this answer :)

I surveyed a few Excel modules for Python, and found openpyxl to be the best.

The free book Automate the Boring Stuff with Python has a chapter on openpyxl with more details or you can check the Read the Docs site. You won't need Office or Excel installed in order to use openpyxl.

Your program would look something like this:

import openpyxl
wb = openpyxl.load_workbook('example.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')

stimulusTimes = [1, 2, 3]
reactionTimes = [2.3, 5.1, 7.0]

for i in range(len(stimulusTimes)):
    sheet['A' + str(i + 6)].value = stimulusTimes[i]
    sheet['B' + str(i + 6)].value = reactionTimes[i]

wb.save('example.xlsx')

I had the same problem but none of the answer above worked. Here's what did the job for me:

1. download msvcr110.dll, msvcr120.dll, msvcp120.dll and vcruntime140.dll from dll-files.com
2. Copy them into System32

You can 'slice' a string very easily, just like you'd pull items from a list:

a_string = 'This is a string'

To get the first 4 letters:

first_four_letters = a_string[:4]
>>> 'This'

Or the last 5:

last_five_letters = a_string[-5:]
>>> 'string'

So applying that logic to your problem:

the_string = '416d76b8811b0ddae2fdad8f4721ddbe|d4f656ee006e248f2f3a8a93a8aec5868788b927|12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f '
first_32_chars = the_string[:32]
>>> 416d76b8811b0ddae2fdad8f4721ddbe

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

you can give it a max-height and max-width in your .css

.fontpixel{max-width:200px; max-height:200px;}

in addition to your height and width properties

In case you get a cross-domain error:

If you have control over the content of the iframe - that is, if it is merely loaded in a cross-origin setup such as on Amazon Mechanical Turk - you can circumvent this problem with the <body onload='my_func(my_arg)'> attribute for the inner html.

For example, for the inner html, use the this html parameter (yes - this is defined and it refers to the parent window of the inner body element):

<body onload='changeForm(this)'>

In the inner html :

    function changeForm(window) {
        console.log('inner window loaded: do whatever you want with the inner html');
        window.document.getElementById('mturk_form').style.display = 'none';
    </script>

To get insight on every function calls recursively, do:

%load_ext snakeviz
%%snakeviz

It just takes those 2 lines of code in a Jupyter notebook, and it generates a nice interactive diagram. For example:

Here is the code. Again, the 2 lines starting with % are the only extra lines of code needed to use snakeviz:

# !pip install snakeviz
%load_ext snakeviz
import glob
import hashlib

%%snakeviz

files = glob.glob('*.txt')
def print_files_hashed(files):
    for file in files:
        with open(file) as f:
            print(hashlib.md5(f.read().encode('utf-8')).hexdigest())
print_files_hashed(files)

It also seems possible to run snakeviz outside notebooks. More info on the snakeviz website.

If they need to be floated, you could always just set the min-height to 1px so they don't collapse.

this is my full solution which would read any base64 image format and save it in the proper format in the database:

    // Save base64 image to disk
    try
    {
        // Decoding base-64 image
        // Source: http://stackoverflow.com/questions/20267939/nodejs-write-base64-image-file
        function decodeBase64Image(dataString) 
        {
          var matches = dataString.match(/^data:([A-Za-z-+\/]+);base64,(.+)$/);
          var response = {};

          if (matches.length !== 3) 
          {
            return new Error('Invalid input string');
          }

          response.type = matches[1];
          response.data = new Buffer(matches[2], 'base64');

          return response;
        }

        // Regular expression for image type:
        // This regular image extracts the "jpeg" from "image/jpeg"
        var imageTypeRegularExpression      = /\/(.*?)$/;      

        // Generate random string
        var crypto                          = require('crypto');
        var seed                            = crypto.randomBytes(20);
        var uniqueSHA1String                = crypto
                                               .createHash('sha1')
                                                .update(seed)
                                                 .digest('hex');

        var base64Data = 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAZABkAAD/4Q3zaHR0cDovL25zLmFkb2JlLmN...';

        var imageBuffer                      = decodeBase64Image(base64Data);
        var userUploadedFeedMessagesLocation = '../img/upload/feed/';

        var uniqueRandomImageName            = 'image-' + uniqueSHA1String;
        // This variable is actually an array which has 5 values,
        // The [1] value is the real image extension
        var imageTypeDetected                = imageBuffer
                                                .type
                                                 .match(imageTypeRegularExpression);

        var userUploadedImagePath            = userUploadedFeedMessagesLocation + 
                                               uniqueRandomImageName +
                                               '.' + 
                                               imageTypeDetected[1];

        // Save decoded binary image to disk
        try
        {
        require('fs').writeFile(userUploadedImagePath, imageBuffer.data,  
                                function() 
                                {
                                  console.log('DEBUG - feed:message: Saved to disk image attached by user:', userUploadedImagePath);
                                });
        }
        catch(error)
        {
            console.log('ERROR:', error);
        }

    }
    catch(error)
    {
        console.log('ERROR:', error);
    }

Just add the class disabled on your anchor:

And you are free to go.

SCENARIO 1 - wait for async task completion: I agree that WaitHandle/Auto|ManualResetEvent should be used in scenario where a thread is waiting for task on another thread to complete.

SCENARIO 2 - timing while loop: However, as a crude timing mechanism (while+Thread.Sleep) is perfectly fine for 99% of applications which does NOT require knowing exactly when the blocked Thread should "wake up*. The argument that it takes 200k cycles to create the thread is also invalid - the timing loop thread needs be created anyway and 200k cycles is just another big number (tell me how many cycles to open a file/socket/db calls?).

So if while+Thread.Sleep works, why complicate things? Only syntax lawyers would, be practical!

There are two ways to do this. One is very simple but unsafe:

Map<String, Object> map = new HashMap<String, Object>();
Map<String, String> newMap = new HashMap<String, String>((Map)map);  // unchecked warning

The other way has no compiler warnings and ensures type safety at runtime, which is more robust. (After all, you can't guarantee the original map contains only String values, otherwise why wouldn't it be Map<String, String> in the first place?)

Map<String, Object> map = new HashMap<String, Object>();
Map<String, String> newMap = new HashMap<String, String>();
@SuppressWarnings("unchecked") Map<String, Object> intermediate =
    (Map)Collections.checkedMap(newMap, String.class, String.class);
intermediate.putAll(map);

Use Sum()

 List<string> foo = new List<string>();
 foo.Add("1");
 foo.Add("2");
 foo.Add("3");
 foo.Add("4");

 Console.Write(foo.Sum(x => Convert.ToInt32(x)));

Prints:

10

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

Take the time to read through Creating a GUI with Swing and Laying components out in a container

As an even easier solution, you could just use:

$results = $objects.Name

Which should fill $results with an array of all the 'Name' property values of the elements in $objects.

You can redirect the output of a cmd prompt to a file using > or >> to append to a file.

i.e.

echo Hello World >C:\output.txt
echo Hello again! >>C:\output.txt

or

mybatchfile.bat >C:\output.txt

Note that using > will automatically overwrite the file if it already exists.

You also have the option of redirecting stdin, stdout and stderr.

See here for a complete list of options.

Your log indicates ClientAbortException, which occurs when your HTTP client drops the connection with the server and this happened before server could close the server socket Connection.

It depends on your requirements.

Page Load : Perform actions common to all requests, such as setting up a database query. At this point, server controls in the tree are created and initialized, the state is restored, and form controls reflect client-side data. See Handling Inherited Events.

Prerender :Perform any updates before the output is rendered. Any changes made to the state of the control in the prerender phase can be saved, while changes made in the rendering phase are lost. See Handling Inherited Events.

Since the border is used just for visual appearance, you could put it into the ListBoxItem's ControlTemplate and modify the properties there. In the ItemTemplate, you could place only the StackPanel and the TextBlock. In this way, the code also remains clean, as in the appearance of the control will be controlled via the ControlTemplate and the data to be shown will be controlled via the DataTemplate.

This is a great wrapper, but when posting to a asp.net web page, two additional post values need to be set:

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    //ADD THESE, BECAUSE ASP.NET is Expecting them for validation
    //Even if they are empty you will be able to post the file
    [request setPostValue:@"" forKey:@"__VIEWSTATE"];
    [request setPostValue:@"" forKey:@"__EVENTVALIDATION"]; 
    ///

    [request setFile:FIleName forKey:@"fileupload_control_Name"];
    [request startSynchronous];

I have used sequelize.js, node.js and transaction in below code and added proper error handling if it doesn't find data it will throw error that no data found with that id

editLocale: async (req, res) => {

    sequelize.sequelize.transaction(async (t1) => {

        if (!req.body.id) {
            logger.warn(error.MANDATORY_FIELDS);
            return res.status(500).send(error.MANDATORY_FIELDS);
        }

        let id = req.body.id;

        let checkLocale= await sequelize.Locale.findOne({
            where: {
                id : req.body.id
            }
        });

        checkLocale = checkLocale.get();
        if (checkLocale ) {
            let Locale= await sequelize.Locale.update(req.body, {
                where: {
                    id: id
                }
            });

            let result = error.OK;
            result.data = Locale;

            logger.info(result);
            return res.status(200).send(result);
        }
        else {
            logger.warn(error.DATA_NOT_FOUND);
            return res.status(404).send(error.DATA_NOT_FOUND);
        }
    }).catch(function (err) {
        logger.error(err);
        return res.status(500).send(error.SERVER_ERROR);
    });
},

A two line intuitive solution to round to a given time unit, here seconds, for a datetime object t:

format_str = '%Y-%m-%d %H:%M:%S'
t_rounded = datetime.strptime(datetime.strftime(t, format_str), format_str)

If you wish to round to a different unit simply alter format_str.

This approach does not round to arbitrary time amounts as above methods, but is a nicely Pythonic way to round to a given hour, minute or second.

Here is a more browser-safe solution:

    $fp = @fopen($yourfile, 'rb');

    if (strstr($_SERVER['HTTP_USER_AGENT'], "MSIE"))
{
    header('Content-Type: "application/octet-stream"');
    header('Content-Disposition: attachment; filename="yourname.file"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header("Content-Transfer-Encoding: binary");
    header('Pragma: public');
    header("Content-Length: ".filesize($yourfile));
}
else
{
    header('Content-Type: "application/octet-stream"');
    header('Content-Disposition: attachment; filename="yourname.file"');
    header("Content-Transfer-Encoding: binary");
    header('Expires: 0');
    header('Pragma: no-cache');
    header("Content-Length: ".filesize($yourfile));
}

fpassthru($fp);
fclose($fp);

The solution for me was to update guest additions

Is this what you're looking for?

if (request instanceof HttpServletRequest) {
 String url = ((HttpServletRequest)request).getRequestURL().toString();
 String queryString = ((HttpServletRequest)request).getQueryString();
}

To Reconstruct:

System.out.println(url + "?" + queryString);

Info on HttpServletRequest.getRequestURL() and HttpServletRequest.getQueryString().

If you inherit from Exception, you have to provide a constructor that takes a String as a parameter (it will contain the error message).

I think you're looking for Hping (http://www.hping.org/), which has a Windows version.

"The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP, ICMP..."

It's also very useful if you want to see where along a route that a TCP port is being blocked (like by a firewall), where ICMP might not be.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

I do wonder if perhaps you should iterate over the exploded HTTP_X_FORWARDED_FOR in reverse order, since my experience has been that the user's IP address ends up at the end of the comma-separated list, so starting at the start of the header, you're more likely to get the ip address of one of the proxies returned, which could potentially still allow session hijacking as many users may come through that proxy.

You can use this small library: https://github.com/ledfusion/php-rest-curl

Making a call is as simple as:

// GET
$result = RestCurl::get($URL, array('id' => 12345678));

// POST
$result = RestCurl::post($URL, array('name' => 'John'));

// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));

// DELETE
$result = RestCurl::delete($URL); 

And for the $result variable:

• $result['status'] is the HTTP response code
• $result['data'] an array with the JSON response parsed
• $result['header'] a string with the response headers

Hope it helps

On MVC 5 is quite similar

@Html.ActionLink("LinkText", "ActionName", new { id = "id" })

JSONArray may be what you want.

String message;
JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");
item.put("id", 3);
item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

Wikipedia has a comprehensive list of unit testing frameworks, with tables that identify features supported or not.

You can actually just use

$("#form").attr("target", "NewAction");

As far as I know, this will NOT fail silently.

If the page is opening in a new target, you may need to make sure the URL is unique each time because Webkit (chrome/safari) will cache the fact you have visited that URL and won't perform the post.

For example

$("form").attr("action", "/Pages/GeneratePreview?" + new Date().getMilliseconds());

On Linux (and probably most Unix), there is no OS-level DNS caching unless nscd is installed and running. Even then, the DNS caching feature of nscd is disabled by default at least in Debian because it's broken. The practical upshot is that your linux system very very probably does not do any OS-level DNS caching.

You could implement your own cache in your application (like they did for Squid, according to diegows's comment), but I would recommend against it. It's a lot of work, it's easy to get it wrong (nscd got it wrong!!!), it likely won't be as easily tunable as a dedicated DNS cache, and it duplicates functionality that already exists outside your application.

If an end user using your software needs to have DNS caching because the DNS query load is large enough to be a problem or the RTT to the external DNS server is long enough to be a problem, they can install a caching DNS server such as Unbound on the same machine as your application, configured to cache responses and forward misses to the regular DNS resolvers.

I found this thread looking for a way to control Shift + any key. I pasted together other solutions to make this combined function to accomplish what I needed. I hope it helps someone else.

function () {
    return this.each(function () {
    $(this).keydown(function (e) {
        var key = e.charCode || e.keyCode || 0;
        // Shift + anything is not desired
        if (e.shiftKey) {
            return false;
        }
        // allow backspace, tab, delete, enter, arrows, numbers 
        //and keypad numbers ONLY
        // home, end, period, and numpad decimal
        return (
            key == 8 ||
            key == 9 ||
            key == 13 ||
            key == 46 ||
            key == 110 ||
            key == 190 ||
            (key >= 35 && key <= 40) ||
            (key >= 48 && key <= 57) ||
            (key >= 96 && key <= 105));
    });
});

In the AWS console, if you navigate to S3, you will see your folders listed. If you navigate to the folder, you will see the object (s) listed. right click and you can rename. OR, you can check the box in front of your object, then from the pull down menu named ACTIONS, you can select rename. Just worked for me, 3-31-2019

You can always use "FAR" = "Find and Replace". It's written under java, so it works where Java works (pretty much everywhere). Works with directories and subdirectories, searches and replaces within files, also can renames them. Also can rename bulk files.Licence = free, for both individuals or comapnies. Very fast and maintained by the developer. Find it here: http://findandreplace.sourceforge.net/

Also you can use GrepWin. Works pretty much the same. You can find it here: http://tools.tortoisesvn.net/grepWin.html

I don't know what is the value/usefulness of renaming a function and call it with the new name. But using a string as function name, e.g. obtained from the command line, has some value/usefulness:

import sys
fun = eval(sys.argv[1])
fun()

In the present case, fun = x.

It can also be caused by this bug, if you're having Eclipse 4.5/4.6, an Eclipse Xtext plugin version older than v2.9.0, and a particular workspace configuration.

The workaround would be to create a new workspace and import the existing projects.

You can create multiple workspaces in Eclipse. You have to just specify the path of the workspace during Eclipse startup. You can even switch workspaces via File?Switch workspace.

You can then import project to your workspace, copy paste project to your new workspace folder, then

File?Import?Existing project in to workspace?select project.

From Christoffer Noring, Pablo Deeleman's book “Learning Angular - Second Edition”:

"As our applications grow and evolves, each one of our code entities will internally require instances of other objects, which are better known as dependencies in the world of software engineering. The action of passing such dependencies to the dependent client is known as injection, and it also entails the participation of another code entity, named the injector. The injector will take responsibility for instantiating and bootstrapping the required dependencies so they are ready for use from the very moment they are successfully injected in the client. This is very important since the client knows nothing about how to instantiate its own dependencies and is only aware of the interface they implement in order to use them."

From: Anton Moiseev. book “Angular Development with Typescript, Second Edition.”:

“In short, DI helps you write code in a loosely coupled way and makes your code more testable and reusable.”

If you want to enable ping (from anywhere) programmatically, via the SDK, the magic formula is:

cidrIp:     "0.0.0.0/0"
ipProtocol: "icmp"
toPort:     -1
fromPort:   8

For example, in Scala (using the AWS Java SDK v2), the following works to define an IpPermission for the authorizeSecurityGroupIngress endpoint.

  val PingPermission = {
    val range = IpRange.builder().cidrIp( "0.0.0.0/0" ).build()
    IpPermission.builder().ipProtocol( "icmp" ).ipRanges( range ).toPort( -1 ).fromPort( 8 ).build()
  }

(I've tried this is only on EC2-Classic. I don't know what egress rules might be necessary under a VPC)

I offer one more solution in case it is worthful for someone else.

I have a history.js file where I have the following:

import createHistory from 'history/createBrowserHistory'
const history = createHistory()
history.pushLater = (...args) => setImmediate(() => history.push(...args))
export default history

Next, on my Root where I define my router I use the following:

import history from '../history'
import { Provider } from 'react-redux'
import { Router, Route, Switch } from 'react-router-dom'

export default class Root extends React.Component {
  render() {
    return (
     <Provider store={store}>
      <Router history={history}>
       <Switch>
        ...
       </Switch>
      </Router>
     </Provider>
    )
   }
  }

Finally, on my actions.js I import History and make use of pushLater

import history from './history'
export const login = createAction(
...
history.pushLater({ pathname: PATH_REDIRECT_LOGIN })
...)

This way, I can push to new actions after API calls.

Hope it helps!

Save the archiveName image to a tar file. I will use the /media/sf_docker_vm/ to save the image.

stratos@Dev-PC:~$ docker save imageID > /media/sf_docker_vm/archiveName.tar

Copy the archiveName.tar file to your new Docker instance using whatever method works in your environment, for example FTP, SCP, etc.

Run the docker load command on your new Docker instance and specify the location of the image tar file.

stratos@Dev-PC:~$ docker load < /media/sf_docker_vm/archiveName.tar

Finally, run the docker images command to check that the image is now available.

stratos@Dev-PC:~$ docker images

Please find this detailed post.

Rather than use Ajax / XMLHttpRequest / $http to invoke your WebApi method, use an html form. That way the browser saves the file using the filename and content type information in the response headers, and you don't need to work around javascript's limitations on file handling. You might also use a GET method rather than a POST as the method returns data. Here's an example form:

<form name="export" action="/MyController/Export" method="get" novalidate>
    <input name="id" type="id" ng-model="id" placeholder="ID" />
    <input name="fileName" type="text" ng-model="filename" placeholder="file name" required />
    <span class="error" ng-show="export.fileName.$error.required">Filename is required!</span>
    <button type="submit" ng-disabled="export.$invalid">Export</button>
</form>

Not sure if that's useful, but, if you need a long URL from desktop browser to be opened in mobile browser, you can send SMS with that URL and open directly from message app.

They're the same, aren't they? Now I'm losing confidence in myself but I really thought IPv6 was just an addressing change. TCP and UDP are still addressed as they are under IPv4.

Try the Leaflet.awesome-markers lib -- it allows you to set colors and other styles.

I catch this exception when Java out of heap. If I try to put in RAM many data items - first I catch "Communications link failure" and next "OutOfMemoryError".

I logged it and I decrease memory consumption (delete 1/2 data) and all ok.

rabbitmqadmin list queues|awk 'NR>3{print $4}'|head -n-1|xargs -I qname rabbitmqadmin delete queue name=qname

The answer that Pablo Santa Cruz gave is correct; however, in case anybody stumbled on this page and wants more clarification, here is a detailed breakdown.

Example Tables

Suppose we have the following tables:

-- t1
id  name
1   Tim
2   Marta

-- t2
id  name
1   Tim
3   Katarina

Inner Joins

An inner join, like this:

SELECT *
FROM `t1`
INNER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

Would get us only records that appear in both tables, like this:

1 Tim  1 Tim

Inner joins don't have a direction (like left or right) because they are explicitly bidirectional - we require a match on both sides.

Outer Joins

Outer joins, on the other hand, are for finding records that may not have a match in the other table. As such, you have to specify which side of the join is allowed to have a missing record.

LEFT JOIN and RIGHT JOIN are shorthand for LEFT OUTER JOIN and RIGHT OUTER JOIN; I will use their full names below to reinforce the concept of outer joins vs inner joins.

Left Outer Join

A left outer join, like this:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

...would get us all the records from the left table regardless of whether or not they have a match in the right table, like this:

1 Tim   1    Tim
2 Marta NULL NULL

Right Outer Join

A right outer join, like this:

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

...would get us all the records from the right table regardless of whether or not they have a match in the left table, like this:

1    Tim   1  Tim
NULL NULL  3  Katarina

Full Outer Join

A full outer join would give us all records from both tables, whether or not they have a match in the other table, with NULLs on both sides where there is no match. The result would look like this:

1    Tim   1    Tim
2    Marta NULL NULL
NULL NULL  3    Katarina

However, as Pablo Santa Cruz pointed out, MySQL doesn't support this. We can emulate it by doing a UNION of a left join and a right join, like this:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`

UNION

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

You can think of a UNION as meaning "run both of these queries, then stack the results on top of each other"; some of the rows will come from the first query and some from the second.

It should be noted that a UNION in MySQL will eliminate exact duplicates: Tim would appear in both of the queries here, but the result of the UNION only lists him once. My database guru colleague feels that this behavior should not be relied upon. So to be more explicit about it, we could add a WHERE clause to the second query:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`

UNION

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`
WHERE `t1`.`id` IS NULL;

On the other hand, if you wanted to see duplicates for some reason, you could use UNION ALL.

I liked Levit's answer and ended up using it. But I just wanted to point out, just in case, that there is an official Google PHP library for new reCAPTCHA: https://github.com/google/recaptcha

The latest version (right now 1.1.2) supports Composer and contains an example that you can run to see if you have configured everything correctly.

Below you can see part of the example that comes with this official library (with my minor modifications for clarity):

// Make the call to verify the response and also pass the user's IP address
    $resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);

    if ($resp->isSuccess()) {
// If the response is a success, that's it!
        ?>
        <h2>Success!</h2>
        <p>That's it. Everything is working. Go integrate this into your real project.</p>
        <p><a href="/">Try again</a></p>
        <?php
    } else {
// If it's not successful, then one or more error codes will be returned.
        ?>
        <h2>Something went wrong</h2>
        <p>The following error was returned: <?php
            foreach ($resp->getErrorCodes() as $code) {
                echo '<tt>' , $code , '</tt> ';
            }
            ?></p>
        <p>Check the error code reference at <tt><a href="https://developers.google.com/recaptcha/docs/verify#error-code-reference">https://developers.google.com/recaptcha/docs/verify#error-code-reference</a></tt>.
        <p><strong>Note:</strong> Error code <tt>missing-input-response</tt> may mean the user just didn't complete the reCAPTCHA.</p>
        <p><a href="/">Try again</a></p>
    <?php
    }

Hope it helps someone.

A native way with latest .NET 4.5 framework, but entirely feature-less:

Creation:

Add-Type -Assembly "System.IO.Compression.FileSystem" ;
[System.IO.Compression.ZipFile]::CreateFromDirectory("c:\your\directory\to\compress", "yourfile.zip") ;

Extraction:

Add-Type -Assembly "System.IO.Compression.FileSystem" ;
[System.IO.Compression.ZipFile]::ExtractToDirectory("yourfile.zip", "c:\your\destination") ;

As mentioned, totally feature-less, so don't expect an overwrite flag.

UPDATE: See below for other developers that have expanded on this over the years...

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

I found the solution:

In your activity which has the Theme.Dialog style set, do this:

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

    setContentView(R.layout.your_layout);

    getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}

It's important that you call Window.setLayout() after you call setContentView(), otherwise it won't work.

For java, you also need to learn how to use an IDE and setup your environment and this kind of this to make java works...

Then for J2ME, you'll need to know things about embedded/mobile systems....

10 weeks with the tutorials would be ok but it also depends on what you're going to do in your j2me course...

I would go head first in a j2me tutorial (assuming you know a minimum concerning variables functions and OO)...

good luck...

This works well for me, and I'm handling hover and click CSS as well (by changing background color):

HTML (here showing 2 images, image1 on top of image2):

<button class="iconButton" style="background-image: url('image1.png'), url('image2.png')"
  onclick="alert('clicked');"></button>

CSS (my images are 32px X 32px, so I gave them 4px for padding and a 5px border rounding):

.iconButton {
    width: 36px;
    height: 36px;
    background-color: #000000;
    background-position: center;
    background-repeat: no-repeat;
    border: none;
    border-radius: 5px;
    cursor: pointer;
    outline: none;
}

.iconButton:hover {
    background-color: #303030;
}

.iconButton:active {
    background-color: #606060;
}

button::-moz-focus-inner {
    border: 0;
}

A CSS only solution for those who are having trouble with mobile touchscreen button styling.

This will fix your hover-stick / active button problems.

body, html {
  width: 600px;
}
p {
  font-size: 20px;
}

  border-radius: 30px;
  background: #00aeff;
  font-size: 20px;
}

button:active {
  background: black;
  color: white;
}

.delayed {
  transition: all 0.2s;
  transition-delay: 300ms;
}

.delayed:active {
  transition: none;
}

<h1>Sticky styles for better touch screen buttons!</h1>

<button>Normal button</button>

<button class="delayed"><a href="https://www.google.com"/>Delayed style</a></button>

<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures.   With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely.  This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>

<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

Here is a simple solution, which uses a deep object comparison to check for duplicates (without resorting to converting to JSON, which is inefficient and hacky)

var newArr = _.filter(oldArr, function (element, index) {
    // tests if the element has a duplicate in the rest of the array
    for(index += 1; index < oldArr.length; index += 1) {
        if (_.isEqual(element, oldArr[index])) {
            return false;
        }
    }
    return true;
});

It filters out all elements if they have a duplicate later in the array - such that the last duplicate element is kept.

The testing for a duplicate uses _.isEqual which performs an optimised deep comparison between the two objects see the underscore isEqual documentation for more info.

edit: updated to use _.filter which is a cleaner approach

I found an up-to-date & unparalleled solution: https://www.npmjs.com/package/ts-mixer

You are welcome :)

I developed a multithreaded swing based simulation of robot navigation through a set of randomized grid terrain of food sources and mines and developed a genetic algorithm based strategy of exploring the optimization of robotic behavior and survival of fittest genes for a robotic chromosome. This was done using charting and mapping of each iteration cycle.

Since, then I have developed even more game behavior. An example application I built recently for myself was a genetic algorithm for solving the traveling sales man problem in route finding in UK taking into account start and goal states as well as one/multiple connection points, delays, cancellations, construction works, rush hour, public strikes, consideration between fastest vs cheapest routes. Then providing a balanced recommendation for the route to take on a given day.

Generally, my strategy is to use POJO based representaton of genes then I apply specific interface implementations for selection, mutation, crossover strategies, and the criteria point. My fitness function then basically becomes a quite complex based on the strategy and criteria I need to apply as a heuristic measure.

I have also looked into applying genetic algorithm into automated testing within code using systematic mutation cycles where the algorithm understands the logic and tries to ascertain a bug report with recommendations for code fixes. Basically, a way to optimize my code and provide recommendations for improvement as well as a way of automating the discovery of new programmatic code. I have also tried to apply genetic algorithms to music production amongst other applications.

Generally, I find evolutionary strategies like most metaheuristic/global optimization strategies, they are slow to learn at first but start to pick up as the solutions become closer and closer to goal state and as long as your fitness function and heuristics are well aligned to produce that convergence within your search space.

It may be curable by increasing the stack size - but a better solution would be to work out how to avoid recursing so much. A recursive solution can always be converted to an iterative solution - which will make your code scale to larger inputs much more cleanly. Otherwise you'll really be guessing at how much stack to provide, which may not even be obvious from the input.

Are you absolutely sure it's failing due to the size of the input rather than a bug in the code, by the way? Just how deep is this recursion?

EDIT: Okay, having seen the update, I would personally try to rewrite it to avoid using recursion. Generally having a Stack<T> of "things still do to" is a good starting point to remove recursion.

Every answer I've read indicates the SUBSYSTEM=="usb". However, my (perhaps ancient) udev needed this to be changed to DRIVER=="usb". At last I can run the adb server as a non-root user... yay.

It can be instructive to look at the output of udevmonitor --env, followed by the output of

udevinfo -a -p <DEVICE_PATH_AS_REPORTED_BY-udevmonitor>

With CLI in one line :

mysql --user=root --password=pass --host=localhost db_name --execute='select version()';

or

mysql -uroot -ppass -hlocalhost db_name -e 'select version()';

return something like this :

+-----------+
| version() |
+-----------+
| 5.6.34    |
+-----------+

The Google collections framework offers a good and elegant way to achieve the null check.

There is a method in a library class like this:

static <T> T checkNotNull(T e) {
   if (e == null) {
      throw new NullPointerException();
   }
   return e;
}

And the usage is (with import static):

...
void foo(int a, Person p) {
   if (checkNotNull(p).getAge() > a) {
      ...
   }
   else {
      ...
   }
}
...

Or in your example:

checkNotNull(someobject).doCalc();

The easiest way only if you don't need return something it'ts just return null

With Project JUnion you can use structs in Java by annotating a class with @Struct annotation

@Struct
class Member {
  string FirstName; 
  string LastName;  
  int BirthYear; 
}

Be careful: while the string representations for .NET Guid and (RFC4122) UUID are identical, the storage format is not. .NET trades in little-endian bytes for the first three Guid parts.

If you are transmitting the bytes (for example, as base64), you can't just use Guid.ToByteArray() and encode it. You'll need to Array.Reverse the first three parts (Data1-3).

I do it this way:

var rfc4122bytes = Convert.FromBase64String("aguidthatIgotonthewire==");
Array.Reverse(rfc4122bytes,0,4);
Array.Reverse(rfc4122bytes,4,2);
Array.Reverse(rfc4122bytes,6,2);
var guid = new Guid(rfc4122bytes);

See this answer for the specific .NET implementation details.

Edit: Thanks to Jeff Walker, Code Ranger, for pointing out that the internals are not relevant to the format of the byte array that goes in and out of the byte-array constructor and ToByteArray().

For me, the only way to reset the failed cherry-pick-attempt was

git reset --hard HEAD

int w =0 , l =0, d=0, i=0;
    Scanner sc = new Scanner(System.in);

// try tentimes
    while (i<10) {


        System.out.println("scissor(1) ,Rock(2),Paper(3) ");
        int n = sc.nextInt();
        int m =(int)(Math.random()*3+1);


        if(n==m){

            System.out.println("Com:"+m +"so>>> " + "draw");
            d++;


        }else if ((n-1)%3==(m%3)){
            w++;
            System.out.println("Com:"+m +"so>>> " +"win");
        }
        else if(n >=4 )
        {
            System.out.println("pleas enter correct number)");


    }
        else {
            System.out.println("Com:"+m +"so>>> " +"lose");
            l++;

        }
        i++;

simple way:Add a "center" tag before the form tag

Update:

In Python 3.8, the prod function was added to the math module. See: math.prod().

Older info: Python 3.7 and prior

The function you're looking for would be called prod() or product() but Python doesn't have that function. So, you need to write your own (which is easy).

Pronouncement on prod()

Yes, that's right. Guido rejected the idea for a built-in prod() function because he thought it was rarely needed.

Alternative with reduce()

As you suggested, it is not hard to make your own using reduce() and operator.mul():

from functools import reduce  # Required in Python 3
import operator
def prod(iterable):
    return reduce(operator.mul, iterable, 1)

>>> prod(range(1, 5))
24

Note, in Python 3, the reduce() function was moved to the functools module.

Specific case: Factorials

As a side note, the primary motivating use case for prod() is to compute factorials. We already have support for that in the math module:

>>> import math

>>> math.factorial(10)
3628800

Alternative with logarithms

If your data consists of floats, you can compute a product using sum() with exponents and logarithms:

>>> from math import log, exp

>>> data = [1.2, 1.5, 2.5, 0.9, 14.2, 3.8]
>>> exp(sum(map(log, data)))
218.53799999999993

>>> 1.2 * 1.5 * 2.5 * 0.9 * 14.2 * 3.8
218.53799999999998

Note, the use of log() requires that all the inputs are positive.

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

The correct format for url can be one of the following formats:

jdbc:oracle:thin:@<hostName>:<portNumber>:<sid>;  (if you have sid)
jdbc:oracle:thin:@//<hostName>:<portNumber>/serviceName; (if you have oracle service name)

And don't put any space there. Try to use 1521 as port number. sid (database name) must be the same as the one which is in environment variables (if you are using windows).

List<String> lines = Files.readAllLines(Paths.get("src/test/resources/foo.txt"));
lines.forEach(System.out::println);

If @Region is not a null value (lets say @Region = 'South') it will not return rows where the Region field is null, regardless of the value of ANSI_NULLS.

ANSI_NULLS will only make a difference when the value of @Region is null, i.e. when your first query essentially becomes the second one.

In that case, ANSI_NULLS ON will not return any rows (because null = null will yield an unknown boolean value (a.k.a. null)) and ANSI_NULLS OFF will return any rows where the Region field is null (because null = null will yield true)

Try starting with the Percona wizard and comparing their recommendations against your current settings one by one. Don't worry there aren't as many applicable settings as you might think.

Everyone points to key_buffer_size first which you have addressed. With 96GB memory I'd be wary of any tiny default value (likely to be only 96M!).

Your modification of sys.path assumes the current working directory is always in main/. This is not the case. Instead, just add the parent directory to sys.path:

import sys
import os.path

sys.path.append(os.path.join(os.path.dirname(__file__), '..'))
import gen_py.lib

Don't forget to include a file __init__.py in gen_py and lib - otherwise, they won't be recognized as Python modules.

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

select substring(ColumnName, patindex('%[^0]%',ColumnName), 10)

Sorry, but--in my opinion--RichieHindle is completely right about saying that method...

It's a function which is a member of a class.

Here is the example of a function that becomes the member of the class. Since then it behaves as a method of the class. Let's start with the empty class and the normal function with one argument:

>>> class C:
...     pass
...
>>> def func(self):
...     print 'func called'
...
>>> func('whatever')
func called

Now we add a member to the C class, which is the reference to the function. After that we can create the instance of the class and call its method as if it was defined inside the class:

>>> C.func = func
>>> o = C()
>>> o.func()
func called

We can use also the alternative way of calling the method:

>>> C.func(o)
func called

The o.func even manifests the same way as the class method:

>>> o.func
<bound method C.func of <__main__.C instance at 0x000000000229ACC8>>

And we can try the reversed approach. Let's define a class and steal its method as a function:

>>> class A:
...     def func(self):
...         print 'aaa'
...
>>> a = A()
>>> a.func
<bound method A.func of <__main__.A instance at 0x000000000229AD08>>
>>> a.func()
aaa

So far, it looks the same. Now the function stealing:

>>> afunc = A.func
>>> afunc(a)
aaa    

The truth is that the method does not accept 'whatever' argument:

>>> afunc('whatever')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method func() must be called with A instance as first 
  argument (got str instance instead)

IMHO, this is not the argument against method is a function that is a member of a class.

Later found the Alex Martelli's answer that basically says the same. Sorry if you consider it duplication :)

If you want to display at row=159220

row=159220

#To display in a table format
display(res.loc[row:row])
display(res.iloc[row:row+1])

#To display in print format
display(res.loc[row])
display(res.iloc[row])

Came across this while looking for help. I was trying to implement the favicon in my Django project and it was not showing -- wanted to add to the conversation.

While trying to implement the favicon in my Django project I renamed the 'favicon.ico' file to 'my_filename.ico' –– the image would not show. After renaming to 'favicon.ico' resolved the issue and graphic displayed. below is the code that resolved my issue:

<link rel="shortcut icon" type="image/png" href="{% static 'img/favicon.ico' %}" />

You can use following code to read file in String from resource folder.

final Resource resource = new ClassPathResource("public.key");
String publicKey = null;
try {
     publicKey = new String(Files.readAllBytes(resource.getFile().toPath()), StandardCharsets.UTF_8);
} catch (IOException e) {
     e.printStackTrace();
}

Here is an option with only a single comparison.

// return true if in range, otherwise false
function inRange(x, min, max) {
    return ((x-min)*(x-max) <= 0);
}

console.log(inRange(5, 1, 10));     // true
console.log(inRange(-5, 1, 10));    // false
console.log(inRange(20, 1, 10));    // false

It is better to use this syntax to replace all the commas in a case of a million 1,234,567

var string = "1,234,567";
string = string.replace(/[^\d\.\-]/g, ""); 
var number = parseFloat(string);
console.log(number)

The g means to remove all commas.

Check the Jsfiddle demo here.

If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b is a power of two, a % b == a & (b - 1).

For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63, because 63 is 111111 in binary.

The masked, higher digits are not of interest to us. Try it out!

Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!

The original question hinted that it would be nice to be able to filter all the properties based on a prefix. I have just confirmed that this works as of Spring Boot 2.1.1.RELEASE, for Properties or Map<String,String>. I'm sure it's worked for while now. Interestingly, it does not work without the prefix = qualification, i.e. I do not know how to get the entire environment loaded into a map. As I said, this might actually be what OP wanted to begin with. The prefix and the following '.' will be stripped off, which might or might not be what one wants:

@ConfigurationProperties(prefix = "abc")
@Bean
public Properties getAsProperties() {
    return new Properties();
}

@Bean
public MyService createService() {
    Properties properties = getAsProperties();
    return new MyService(properties);
}

Postscript: It is indeed possible, and shamefully easy, to get the entire environment. I don't know how this escaped me:

@ConfigurationProperties
@Bean
public Properties getProperties() {
    return new Properties();
}

SELECT convert(datetime, '23/07/2009', 103)

Swift 3: If you want to round to a certain digit number e.g. 5.678434 -> 5.68 you can just combine the round() or roundf() function with a multiplication:

let value:Float = 5.678434
let roundedValue = roundf(value * 100) / 100
print(roundedValue) //5.68

Strings.xml

<string name="my_text"><Data><![CDATA[<b>Your text</b>]]></Data></string>

To set

textView.setText(Html.fromHtml(getString(R.string.activity_completed_text)));

You only need to include a throws clause on a method if the method throws a checked exception. If the method throws a runtime exception then there is no need to do so.

See here for some background on checked vs unchecked exceptions: http://download.oracle.com/javase/tutorial/essential/exceptions/runtime.html

If the method catches the exception and deals with it internally (as in your second example) then there is no need to include a throws clause.

If someone is looking to sub out more than a comma I'm a fan of:

"1,200".chars.grep(/\d/).join.to_i

dunno about performance but, it is more flexible than a gsub, ie:

"1-200".chars.grep(/\d/).join.to_i

The threadunsafety of SimpleDateFormat should not be an issue if you just create it inside the very same method block as you use it. In other words, you are not assigning it as static or instance variable of a class and reusing it in one or more methods which can be invoked by multiple threads. Only this way the threadunsafety of SimpleDateFormat will be exposed. You can however safely reuse the same SimpleDateFormat instance within the very same method block as it would be accessed by the current thread only.

Also, the java.sql.Timestamp class which you're using there should not be abused as it's specific to the JDBC API in order to be able to store or retrieve a TIMESTAMP/DATETIME column type in a SQL database and convert it from/to java.util.Date.

So, this should do:

Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy h:mm:ss a");
String formattedDate = sdf.format(date);
System.out.println(formattedDate); // 12/01/2011 4:48:16 PM

Assuming all of these columns are int, then the first thing to sort out is converting one or more of them to a better data type - int division performs truncation, so anything less than 100% would give you a result of 0:

select (100.0 * (SPGI09_EARLY_OVER_T – SPGI09_OVER_WK_EARLY_ADJUST_T)) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)
from 
CSPGI09_OVERSHIPMENT 

Here, I've mutiplied one of the numbers by 100.0 which will force the result of the calculation to be done with floats rather than ints. By choosing 100, I'm also getting it ready to be treated as a %.

I was also a little confused by your bracketing - I think I've got it correct - but you had brackets around single values, and then in other places you had a mix of operators (- and /) at the same level, and so were relying on the precedence rules to define which operator applied first.

Try a case statement

WHERE
CASE WHEN @zipCode IS NULL THEN 1
ELSE @zipCode
END

Tiny ES6 solution can look like:

var arr = [{key:"11", value:"1100"},{key:"22", value:"2200"}];
var object = arr.reduce(
  (obj, item) => Object.assign(obj, { [item.key]: item.value }), {});

console.log(object)

Also, if you use object spread, than it can look like:

var object = arr.reduce((obj, item) => ({...obj, [item.key]: item.value}) ,{});

One more solution that is 99% faster is(tested on jsperf):

var object = arr.reduce((obj, item) => (obj[item.key] = item.value, obj) ,{});

Here we benefit from comma operator, it evaluates all expression before comma and returns a last one(after last comma). So we don't copy obj each time, rather assigning new property to it.

You can make an empty commit with git commit --allow-empty, but that will not allow you to commit an empty folder structure as git does not know or care about folders as objects themselves -- just the files they contain.

If you mean a variable at the module level then you can use "globals":

if "var1" not in globals():
    var1 = 4

but the common Python idiom is to initialize it to say None (assuming that it's not an acceptable value) and then testing with if var1 is not None.

To get make to actually ignore errors on a single line, you can simply suffix it with ; true, setting the return value to 0. For example:

rm .lambda .lambda_t .activity .activity_t_lambda 2>/dev/null; true

This will redirect stderr output to null, and follow the command with true (which always returns 0, causing make to believe the command succeeded regardless of what actually happened), allowing program flow to continue.

If path is not hardcoded in any script then your websites should work seamlessly.

If one is used to work with DLL in Windows and would like to skip .so version numbers in linux/QT, adding CONFIG += plugin will take version numbers out. To use absolute path to .so, giving it to linker works fine, as Mr. Klatchko mentioned.

Just include windows.h instead of stdfax or create a clean project without template.

Slightly different option usually works for me:

1. "mvn eclipse:eclipse" for this project in the command line.
2. "Refresh/F5" this project in eclipse.

That's all, no need to re-import but need to have the terminal window handy.

Suppose that you have two handlers, f and g, and want to make sure that they are executed in a known and fixed order, then just encapsulate them:

$("...").click(function(event){
  f(event);
  g(event);
});

In this way there is (from the perspective of jQuery) only one handler, which calls f and g in the specified order.
