The existing answers have quite broken code. The DNS method does not work at all. Here is code that I used to configure my NIC:

public static class NetworkConfigurator

    /// </summary>
    /// <param name="ipAddress">The IP Address</param>

    /// <param name="gateway">The gateway.</param>
    /// <param name="nicDescription"></param>
    /// <remarks>Requires a reference to the System.Management namespace</remarks>
    public static void SetIP(string nicDescription, string[] ipAddresses, string subnetMask, string gateway)
    {
        using (var networkConfigMng = new ManagementClass("Win32_NetworkAdapterConfiguration"))
        {
            using (var networkConfigs = networkConfigMng.GetInstances())
            {
                foreach (var managementObject in networkConfigs.Cast<ManagementObject>().Where(mo => (bool)mo["IPEnabled"] && (string)mo["Description"] == nicDescription))
                {
                    using (var newIP = managementObject.GetMethodParameters("EnableStatic"))
                    {
                        // Set new IP address and subnet if needed
                        if (ipAddresses != null || !String.IsNullOrEmpty(subnetMask))
                        {
                            if (ipAddresses != null)
                            {
                                newIP["IPAddress"] = ipAddresses;
                            }

                            if (!String.IsNullOrEmpty(subnetMask))

                        // Set mew gateway if needed
                        if (!String.IsNullOrEmpty(gateway))
                        {

Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.

I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

I found this:

Full

An easy to use, full page image background template for Bootstrap 3 websites

http://startbootstrap.com/template-overviews/full/

or

using in your main div container:

html

<div class="container-fluid full">


</div>

css:

.full {
    background: url('http://placehold.it/1920x1080') no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    background-size: cover;
    -o-background-size: cover;
    height:100%;
}

What I use for debugging purposes is running the gradle task with stacktrace directly in terminal. Then you don't affect your normal compiles.

From your project root directory, via terminal you can use:

./gradlew assembleMyBuild --stacktrace

It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.

This can also be used

$('#name2').change(function(){
    $('#name').val('');//You can set the first value of first one if that is not empty
});


$('#name').change(function(){
    $('#name2').val('');
});

The things built into swift are still very basic. As they should be at this early stage. But you can add your own stuff with the risk that comes with overloading operators and global domain functions. They will be local to your module though.

let now = NSDate()
let seventies = NSDate(timeIntervalSince1970: 0)

// Standard solution still works
let days = NSCalendar.currentCalendar().components(.CalendarUnitDay, 
           fromDate: seventies, toDate: now, options: nil).day

// Flashy swift... maybe...
func -(lhs:NSDate, rhs:NSDate) -> DateRange {
    return DateRange(startDate: rhs, endDate: lhs)
}

class DateRange {
    let startDate:NSDate
    let endDate:NSDate
    var calendar = NSCalendar.currentCalendar()
    var days: Int {
        return calendar.components(.CalendarUnitDay, 
               fromDate: startDate, toDate: endDate, options: nil).day
    }
    var months: Int {
        return calendar.components(.CalendarUnitMonth, 
               fromDate: startDate, toDate: endDate, options: nil).month
    }
    init(startDate:NSDate, endDate:NSDate) {
        self.startDate = startDate
        self.endDate = endDate
    }
}

// Now you can do this...
(now - seventies).months
(now - seventies).days

Future answer with CSS4 selectors

New CSS Specs contain an experimental :has pseudo selector that might be able to do this thing.

li:has(a:active) {
  /* ... */
}

The browser support on this is basically non-existent at this time, but it is in consideration on the official specs.

Answer in 2012 that was wrong in 2012 and is even more wrong in 2018

While it is true that CSS cannot ASCEND, it is incorrect that you cannot grab the parent element of another element. Let me reiterate:

Using your HTML example code, you are able to grab the li without specifying li

ul * a {
    property:value;
}

In this example, the ul is the parent of some element and that element is the parent of anchor. The downside of using this method is that if there is a ul with any child element that contains an anchor, it inherits the styles specified.

You may also use the child selector as well since you'll have to specify the parent element anyway.

ul>li a {
    property:value;
}

In this example, the anchor must be a descendant of an li that MUST be a child of ul, meaning it must be within the tree following the ul declaration. This is going to be a bit more specific and will only grab a list item that contains an anchor AND is a child of ul.

SO, to answer your question by code.

ul.menu > li a.active {
    property:value;
}

This should grab the ul with the class of menu, and the child list item that contains only an anchor with the class of active.

I have combined some answers from the above thread and come up with the solution below. Although it is simple it can be used as a building block for making more complex key updates from a dictionary.

test_dict = {'a': 1, 'b': 2, 'c': 3}
print(test_dict)
# {'a': 1, 'b': 2, 'c': 3}
prefix = 'up'
def dict_key_update(json_file):    
    new_keys = []
    old_keys = []
    for i,(key,value) in enumerate(json_file.items()):
        old_keys.append(key)
        new_keys.append(str(prefix) + key) # i have updated by adding a prefix to the 
        # key
    for old_key, new_key in zip(old_keys,new_keys):
        print('old {}, new {}'.format(old_key, new_key))
        if new_key!=old_key:  
           json_file[new_key] = json_file.pop(old_key)
     return json_file

test_dict = dict_key_update(test_dict)
print(test_dict)
# {'upa': 1, 'upb': 2, 'upc': 3}

Here is multi threading with a simple example which will be helpful. You can run it and understand easily how multi threading is working in Python. I used a lock for preventing access to other threads until the previous threads finished their work. By the use of this line of code,

tLock = threading.BoundedSemaphore(value=4)

you can allow a number of processes at a time and keep hold to the rest of the threads which will run later or after finished previous processes.

import threading
import time

#tLock = threading.Lock()
tLock = threading.BoundedSemaphore(value=4)
def timer(name, delay, repeat):
    print  "\r\nTimer: ", name, " Started"
    tLock.acquire()
    print "\r\n", name, " has the acquired the lock"
    while repeat > 0:
        time.sleep(delay)
        print "\r\n", name, ": ", str(time.ctime(time.time()))
        repeat -= 1

    print "\r\n", name, " is releaseing the lock"
    tLock.release()
    print "\r\nTimer: ", name, " Completed"

def Main():
    t1 = threading.Thread(target=timer, args=("Timer1", 2, 5))
    t2 = threading.Thread(target=timer, args=("Timer2", 3, 5))
    t3 = threading.Thread(target=timer, args=("Timer3", 4, 5))
    t4 = threading.Thread(target=timer, args=("Timer4", 5, 5))
    t5 = threading.Thread(target=timer, args=("Timer5", 0.1, 5))

    t1.start()
    t2.start()
    t3.start()
    t4.start()
    t5.start()

    print "\r\nMain Complete"

"/tmp/mysql.sock" will be created automatically when you start the MySQL server. So remember to do that before starting the rails server.

For me it worked like I had images in icons folder under src and I wrote below code.

new ImageIcon(getClass().getResource("/icons/rsz_measurment_01.png"));

shopList = [] 
maxLengthList = 6
while len(shopList) < maxLengthList:
    item = input("Enter your Item to the List: ")
    shopList.append(item)
    print shopList
print "That's your Shopping List"
print shopList

             if (reader.HasRows)
            {
                while (reader.Read())
                {
                    comboBox1.Items.Add(reader.GetString(0));
                }
            }
            reader.Close();

            MySqlDataReader reader1 = cmd1.ExecuteReader();
            if (reader1.HasRows)
            {
                while (reader1.Read())
                {
                    listBox1.Items.Add(reader1.GetString(0));
                }
            }
            reader1.Close();

Personally I would suggest this is an error as opposed to a setting that needs adjusting. In my code it was because I had a class that had the same name as a library within one of my controllers and it seemed to trip it up.

Output errors and see where this is being triggered.

By using absolute positioning, you can make <body> or <form> or <div>, fit to your browser page. For example:

<body style="position: absolute; bottom: 0px; top: 0px; left: 0px; right: 0px;">

and then simply put a <div> inside it and use whatever percentage of either height or width you wish

<div id="divContainer" style="height: 100%;">

The accepted answer does not preserve STDERR as a separate file descriptor. That means

./script.sh >/dev/null

will not output bar to the terminal, only to the logfile, and

./script.sh 2>/dev/null

will output both foo and bar to the terminal. Clearly that's not the behaviour a normal user is likely to expect. This can be fixed by using two separate tee processes both appending to the same log file:

#!/bin/bash

# See (and upvote) the comment by JamesThomasMoon1979 
# explaining the use of the -i option to tee.
exec >  >(tee -ia foo.log)
exec 2> >(tee -ia foo.log >&2)

echo "foo"
echo "bar" >&2

(Note that the above does not initially truncate the log file - if you want that behaviour you should add

>foo.log

to the top of the script.)

The POSIX.1-2008 specification of tee(1) requires that output is unbuffered, i.e. not even line-buffered, so in this case it is possible that STDOUT and STDERR could end up on the same line of foo.log; however that could also happen on the terminal, so the log file will be a faithful reflection of what could be seen on the terminal, if not an exact mirror of it. If you want the STDOUT lines cleanly separated from the STDERR lines, consider using two log files, possibly with date stamp prefixes on each line to allow chronological reassembly later on.

mysql int types can do quite a few rows: http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html

I came across this when I wanted to make the axis labels smaller, but leave everything else the same size. The command that worked for me, was to put:

par(cex.axis=0.5)

Before the plot command. Just remember to put:

par(cex.axis=1.0)

After the plot to make sure that the fonts go back to the default size.

I solved it by open a command prompt as an administrator and point to mysql folder -> bin -> mysql.exe. it works

You need to add the python.exe in C://.../Anaconda3 installation file as well as C://.../Anaconda3/Scripts to PATH.

First go to your installation directory, in my case it is installed in C://Users/user/Anaconda3 and shift+right click and press "Open command window here" or it might be "Open powershell here", if it is powershell, just write cmd and hit enter to run command window. Then run the following command setx PATH %cd%

Then go to C://Users/user/Anaconda3/Scripts and open the command window there as above, then run the same command "setx PATH %cd%"

I'm going to test adding the no-store tag to our site to see if this makes a difference to browser caching (Chrome has sometimes been caching the pages). I also found this article very useful on documentation on how and why caching works and will look at ETag's next if the no-store is not reliable:

http://www.mnot.net/cache_docs/

I would go for substr() functionality in MySql.

Basically, this function takes account of three parameters i.e. substr(str,pos,len)

http://www.w3resource.com/mysql/string-functions/mysql-substr-function.php

SELECT * FROM artists 
WHERE lower(substr(name,1,1)) in ('a','b','c');

I do this in a very simple way. Works for me. Any drawbacks?

Array.prototype.isArray = true;

a=[]; b={};
a.isArray  // true
b.isArray  // (undefined -> false)

I've created a plunker based off of the answers here and elsewhere.

Additionally I had to add an @Input, @ViewChild, and ElementRef of the <input> and create and subscribe() to an observable of it.

Angular2 Search Filter: PLUNKR (UPDATE: plunker no longer works)

Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.

Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:] or [._:-], to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:], and I wouldn't call that unconventional.

This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.

If you're using SQL Server, use the SqlBulkCopy class.

For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.

I wanted to comment on the solution provided by np8 but I don't have enough reputation so I'll just mention that you can create a setup.py file exactly as they suggested, and then do pipenv install --dev -e . from the project root directory to turn it into an editable dependency. Then your absolute imports will work e.g. from api.api import foo and you don't have to mess around with system-wide installations.

Documentation

for read of Body , you can to read asynchronously.

use the async method like follow:

public async Task<IActionResult> GetBody()
{
      string body="";
      using (StreamReader stream = new StreamReader(Request.Body))
      {
           body = await stream.ReadToEndAsync();
      }
    return Json(body);
}

Test with postman:

It's working well and tested in Asp.net core version 2.0 , 2.1 , 2.2, 3.0.

I hope is useful.

You could try to assign properties to the ENUM you're trying to create and statically contruct it by using a loaded properties file. Big hack, but it works :)

In case you want to utilize .then() which has a subtle difference in comparison with .done() :

return $.post(url, payload)
.then(
    function (result, textStatus, jqXHR) {
        return result;
    },
    function (jqXHR, textStatus, errorThrown) {
        return console.error(errorThrown);
    });

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

Use doubleValue method present in BigDecimal class :

double doubleValue()

Converts this BigDecimal to a double.

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.

You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig. It will give out some information and your local IP should look like 192.168.1.x.

checkout actual-branch

git merge {{commit-hash}}

Try this function, it's similar to your code but it's a dynamic range.

def unique(a):

    k=0
    while k < len(a):
        if a[k] in a[k+1:]:
            a.pop(k)
        else:
            k=k+1



    return a

git stash is your friend.

If you have not made the commit yet, just run git stash. This will save away all of your changes.

Switch to the branch you want the changes on and run git stash pop.

There are lots of uses for git stash. This is certainly one of the more useful reasons.

An example:

# work on some code
git stash
git checkout correct-branch
git stash pop

I used Beetroot-Betroot's solution, but instead of using contains, I used containsNC, which makes it case insensitive.

$.extend($.expr[":"], {
"containsNC": function(elem, i, match, array) {
return (elem.textContent || elem.innerText ||
"").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;
}
});

there is an even simpler way of emulating a switch structure that uses instanceof, you do this by creating a code block in your method and naming it with a label. Then you use if structures to emulate the case statements. If a case is true then you use the break LABEL_NAME to get out of your makeshift switch structure.

        DEFINE_TYPE:
        {
            if (a instanceof x){
                //do something
                break DEFINE_TYPE;
            }
            if (a instanceof y){
               //do something
                break DEFINE_TYPE;
            }
            if (a instanceof z){
                // do something
                break DEFINE_TYPE;
            }
        }

GitHub is a great tool in-all for making repositories. However, it does not do good with private repositories.

You're forced to pay for private repositories unless you get some sort of plan. I have a couple of projects so far, and if GitHub doesn't do what I want I just go to Bitbucket. It's a bit harder to work with than GitHub, however it's unlimited free repositories.

Typings can be configured with the ~/.typingsrc config file. (~ means your home directory)

After finding this issue on github: https://github.com/typings/typings/issues/120, I was able to hack around this issue by creating ~/.typingsrc and setting this configuration:

{
  "proxy": "http://<server>:<port>",
  "rejectUnauthorized": false
}

It also seemed to work without the proxy setting, so maybe it was able to pick that up from the environment somewhere.

This is not a true solution, but was enough for typings to ignore the corporate firewall issues so that I could continue working. I'm sure there is a better solution out there.

In my case, I wanted to center in a parent container with position: absolute.

<div class="absolute-container">
    <div class="parent-container">
        <div class="centered-content">
            My content
        </div>
    </div>
</div>

I had to add some positioning for top, bottom, left & right.

.absolute-container {
    position:absolute;
    top:0;
    left:0;
    bottom:0;
    right:0;
}

.parent-container {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}

.centered-content {
    display: table-cell;
    text-align: center;
    vertical-align: middle
}

On Snow Leopard (OS X 10.6.8), running 'man lsof' yields:

lsof -i 4 -a

(actual manual entry is 'lsof -i 4 -a -p 1234')

The previous answers didn't work on Snow Leopard, but I was trying to use 'netstat -nlp' until I saw the use of 'lsof' in the answer by pts.

For developers who cannot change php configuration because of the webhosting. (My settings 256MB max size, 1000 max variables)

I got the same issue that just 2 out of 5 big data objects (associative arrays) with substructures were received on the server side.

I find out that the whole substructure is being "flattened" in the post request. So, one object becomes a hundreds of literal variables. At the end, instead of 5 Object variables it is in reality sending dozens of hundreds elementar variables.

Solution in this case is to serialize each of the substructures into String. Then it is received on the server as 5 String variables. Example: {variable1:JSON.stringify(myDataObject1),variable2:JSON.stringify(myDataObject2)...}

Yes, you can script using the reg command. Example:

reg add HKCU\Software\SomeProduct
reg add HKCU\Software\SomeProduct /v Version /t REG_SZ /d v2.4.6

This would create key HKEY_CURRENT_USER\Software\SomeProduct, and add a String value "v2.4.6" named "Version" to that key.

reg /? has the details.

Update 2016:

Unfortunately most of the above solutions are out of date and no longer maintained.

There are 3 additional options I can suggest that are still actively developed:

1. BrowseEmAll.Cef

A .Net component that can be used to integrate the Chrome engine into your .Net Application. Based on CefGlue but a little faster on updates to the latest Chrome version. Also there is a commercial support option available which might come in handy for some. Of course the component itself is open source.

2. BrowseEmAll.Gecko

Another .Net component which can be used to integrate the Firefox engine into your .Net application. This is based on Geckofx but unlike the current version of Geckofx this will work with a normal release build of Firefox. To use Geckofx you will need to build Firefox yourself. Again commercial support is available but the component itself is fully open source.

3. BrowseEmAll Core API

Need all the different browsers in your .Net Application? Which the BrowseEmAll Core API you can integrate Chrome, Firefox, Webkit and Internet Explorer into your application. This is a commercial product though so be warned.

(Full disclosure: I work for this company so take everything I say with a grain of salt)

This is the correct and easiest way to accomplish this for 95% of use cases:

>>> df = pd.DataFrame(zip(*[range(10)]), columns=['num'])
>>> df
    num
0    0
1    1
2    2
3    3
4    4
5    5

>>> def example(x):
...     x['p1'] = x['num']**2
...     x['p2'] = x['num']**3
...     x['p3'] = x['num']**4
...     return x

>>> df = df.apply(example, axis=1)
>>> df
    num  p1  p2  p3
0    0   0   0    0
1    1   1   1    1
2    2   4   8   16
3    3   9  27   81
4    4  16  64  256

Example to show last 3 digits of account number.

x = '1234567890'   
x.replace(x[:7], '')

o/p: '890'

<div id="myInfoDiv" seamless="seamless" scrolling="no" style="width:100%; height: 100%; float: left; color: #FFF; background:#ed8719; line-height:100%; font-size:100%; font-family: sans-serif>;

Use the above div and it will not show scroll bar in any browser.

Using CSS you cannot, CSS will only change the appearance of the span. However you can do it without changing the structure of the div by adding an onclick handler to the span:

<html>
<head>
</head>
<body>
<div>
<a href="http://www.google.com">
  <span>title<br></span>
  <span onclick='return false;'>description<br></span>
  <span>some url</span>
</a>
</div>
</body>
</html>

You can then style it so that it looks un-clickable too:

<html>
<head>
     <style type='text/css'>
     a span.unclickable  { text-decoration: none; }
     a span.unclickable:hover { cursor: default; }
     </style>
</head>
<body>
<div>
<a href="http://www.google.com">
  <span>title<br></span>
  <span class='unclickable' onclick='return false;'>description<br></span>
  <span>some url</span>
</a>
</div>
</body>
</html>

Gulp is making issue with Nodejs version 11 and above. Uninstall your current node version and reinstall the v10.15.1 here is link for that version. This helps me and it will solve your problem too.

https://nodejs.org/download/release/v10.15.1/

Following should work

$d = strtotime("+1 months",strtotime("2015-05-25"));
echo   date("Y-m-d",$d); // This will print **2015-06-25** 

INSERT INTO DestinationTable(SupplierName, Country)
SELECT SupplierName, Country FROM SourceTable;

It is not mandatory column names to be same.

Rank each of the squares with numeric scores. If a square is taken, move on to the next choice (sorted in descending order by rank). You're going to need to choose a strategy (there are two main ones for going first and three (I think) for second). Technically, you could just program all of the strategies and then choose one at random. That would make for a less predictable opponent.

It should work as well

Eval("item") == null?"0": Eval("item");

These all get you the line numbers of your current thread and method which work great if you use a try catch where you are expecting an exception. But if you want to catch any unhandled exception then you are using the default uncaught exception handler and current thread will return the line number of the handler function, not the class method that threw the exception. Instead of using Thread.currentThread() simply use the Throwable passed in by the exception handler:

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            public void uncaughtException(Thread t, Throwable e) {              
                if(fShowUncaughtMessage(e,t))               
                    System.exit(1);
            }
        });

In the above use e.getStackTrace()[0] in your handler function (fShowUncaughtMessage) to get the offender.

Note: This answer applies to Windows PowerShell; by contrast, in the cross-platform PowerShell Core edition (v6+), UTF-8 without BOM is the default encoding, across all cmdlets.

• In other words: If you're using PowerShell [Core] version 6 or higher, you get BOM-less UTF-8 files by default (which you can also explicitly request with -Encoding utf8 / -Encoding utf8NoBOM, whereas you get with-BOM encoding with -utf8BOM).

• If you're running Windows 10 and you're willing to switch to BOM-less UTF-8 encoding system-wide - which can have side effects - even Windows PowerShell can be made to use BOM-less UTF-8 consistently - see this answer.

To complement M. Dudley's own simple and pragmatic answer (and ForNeVeR's more concise reformulation):

For convenience, here's advanced function Out-FileUtf8NoBom, a pipeline-based alternative that mimics Out-File, which means:

• you can use it just like Out-File in a pipeline.
• input objects that aren't strings are formatted as they would be if you sent them to the console, just like with Out-File.
• an additional -UseLF switch allows you transform Windows-style CRLF newlines to Unix-style LF-only newlines.

Example:

(Get-Content $MyPath) | Out-FileUtf8NoBom $MyPath # Add -UseLF for Unix newlines

^{Note how (Get-Content $MyPath) is enclosed in (...), which ensures that the entire file is opened, read in full, and closed before sending the result through the pipeline. This is necessary in order to be able to write back to the same file (update it in place).
Generally, though, this technique is not advisable for 2 reasons: (a) the whole file must fit into memory and (b) if the command is interrupted, data will be lost.}

A note on memory use:

• M. Dudley's own answer requires that the entire file contents be built up in memory first, which can be problematic with large files.
• The function below improves on this only slightly: all input objects are still buffered first, but their string representations are then generated and written to the output file one by one.

Source code of function Out-FileUtf8NoBom:

Note: The function is also available as an MIT-licensed Gist, and only it will be maintained going forward.

You can install it directly with the following command (while I can personally assure you that doing so is safe, you should always check the content of a script before directly executing it this way):

function Out-FileUtf8NoBom {
<#
.SYNOPSIS
  Outputs to a UTF-8-encoded file *without a BOM* (byte-order mark).
.DESCRIPTION
  Mimics the most important aspects of Out-File:
    * Input objects are sent to Out-String first.
    * -Append allows you to append to an existing file, -NoClobber prevents
      overwriting of an existing file.
    * -Width allows you to specify the line width for the text representations
       of input objects that aren't strings.
  However, it is not a complete implementation of all Out-File parameters:
    * Only a literal output path is supported, and only as a parameter.
    * -Force is not supported.
    * Conversely, an extra -UseLF switch is supported for using LF-only newlines.
  Caveat: *All* pipeline input is buffered before writing output starts,
          but the string representations are generated and written to the target
          file one by one.
.NOTES
  The raison d'être for this advanced function is that Windows PowerShell
  lacks the ability to write UTF-8 files without a BOM: using -Encoding UTF8 
  invariably prepends a BOM.

For MAC:

1. Install Homebrew
2. brew install postgres
3. initdb /usr/local/var/postgres
4. /usr/local/Cellar/postgresql/<version>/bin/createuser -s postgres or /usr/local/opt/postgres/bin/createuser -s postgres which will just use the latest version.
5. start postgres server manually: pg_ctl -D /usr/local/var/postgres start

To start server at startup

• mkdir -p ~/Library/LaunchAgents
• ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
• launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Now, it is set up, login using psql -U postgres -h localhost or use PgAdmin for GUI.

By default user postgres will not have any login password.

EDIT:

Forgot to say that this solution is in pure js, the only thing you need is a browser that supports promises https://developer.mozilla.org/it/docs/Web/JavaScript/Reference/Global_Objects/Promise

For those who still needs to accomplish such, I've written my own solution that combines promises with timeouts.

Code:

/*
    class: Geolocalizer
        - Handles location triangulation and calculations.
        -- Returns various prototypes to fetch position from strings or coords or dragons or whatever.
*/

var Geolocalizer = function () {
    this.queue          = [];     // queue handler..
    this.resolved       = [];
    this.geolocalizer = new google.maps.Geocoder();  
};

Geolocalizer.prototype = {
    /*
        @fn: Localize
        @scope: resolve single or multiple queued requests.
        @params: <array> needles
        @returns: <deferred> object
    */
    Localize: function ( needles ) {
        var that = this;
        // Enqueue the needles.
        for ( var i = 0; i < needles.length; i++ ) {
            this.queue.push(needles[i]);
        }
        // return a promise and resolve it after every element have been fetched (either with success or failure), then reset the queue.
        return new Promise (
            function (resolve, reject) {
                that.resolveQueueElements().then(function(resolved){
                  resolve(resolved);
                  that.queue    = [];
                  that.resolved = [];
                });
            }
        );
    },

    /*
        @fn: resolveQueueElements
        @scope: resolve queue elements.
        @returns: <deferred> object (promise)
    */

    resolveQueueElements: function (callback) {
        var that = this;
        return new Promise(
            function(resolve, reject) {
                // Loop the queue and resolve each element.
                // Prevent QUERY_LIMIT by delaying actions by one second.
                (function loopWithDelay(such, queue, i){
                    console.log("Attempting the resolution of " +queue[i-1]);
                    setTimeout(function(){
                        such.find(queue[i-1], function(res){
                           such.resolved.push(res); 
                        });
                        if (--i) {
                            loopWithDelay(such,queue,i);
                        }
                    }, 1000);
                })(that, that.queue, that.queue.length);

                // Check every second if the queue has been cleared.
                var it = setInterval(function(){
                    if (that.queue.length == that.resolved.length) {
                        resolve(that.resolved);
                        clearInterval(it);
                    }
                }, 1000);
            }
        );
    },

    /*
        @fn: find
        @scope: resolve an address from string
        @params: <string> s, <fn> Callback
    */
    find: function (s, callback) {
        this.geolocalizer.geocode({
            "address": s
        }, function(res, status){
           if (status == google.maps.GeocoderStatus.OK) {
               var r = {
                   originalString:  s,
                   lat: res[0].geometry.location.lat(),
                   lng: res[0].geometry.location.lng()
               };
               callback(r);
           }
            else {
                callback(undefined);
                console.log(status);
                console.log("could not locate " + s);
            }
        });
    }
};

Please note that it's just a part of a bigger library I wrote to handle google maps stuff, hence comments may be confusing.

Usage is quite simple, the approach, however, is slightly different: instead of looping and resolving one address at a time, you will need to pass an array of addresses to the class and it will handle the search by itself, returning a promise which, when resolved, returns an array containing all the resolved (and unresolved) address.

Example:

var myAmazingGeo = new Geolocalizer();
var locations = ["Italy","California","Dragons are thugs...","China","Georgia"];
myAmazingGeo.Localize(locations).then(function(res){ 
   console.log(res); 
});

Console output:

Attempting the resolution of Georgia
Attempting the resolution of China
Attempting the resolution of Dragons are thugs...
Attempting the resolution of California
ZERO_RESULTS
could not locate Dragons are thugs...
Attempting the resolution of Italy

Object returned:

The whole magic happens here:

(function loopWithDelay(such, queue, i){
                    console.log("Attempting the resolution of " +queue[i-1]);
                    setTimeout(function(){
                        such.find(queue[i-1], function(res){
                           such.resolved.push(res); 
                        });
                        if (--i) {
                            loopWithDelay(such,queue,i);
                    }
                }, 750);
            })(that, that.queue, that.queue.length);

Basically, it loops every item with a delay of 750 milliseconds between each of them, hence every 750 milliseconds an address is controlled.

I've made some further testings and I've found out that even at 700 milliseconds I was sometimes getting the QUERY_LIMIT error, while with 750 I haven't had any issue at all.

In any case, feel free to edit the 750 above if you feel you are safe by handling a lower delay.

Hope this helps someone in the near future ;)

using(StreamWriter writer = new StreamWriter("debug.txt", true))
{
  writer.WriteLine("whatever you text is");
}

The second "true" parameter tells it to append.

This is an example of a very rare occasion where it is recommended to use == instead of ===. Expression somevar == null will return true for undefined and null, but false for everything else (an error if variable is undeclared).

Using the != will flip the result, as expected.

Modern editors will not warn for using == or != operator with null, as this is almost always the desired behavior.

Most common comparisions:

undeffinedVar == null     // true
obj.undefinedProp == null // true
null == null              // true
0 == null                 // false
'0' == null               // false
'' == null                // false

Try it yourself:

let undefinedVar;
console.table([
    { test : undefinedVar,     result: undefinedVar     == null },
    { test : {}.undefinedProp, result: {}.undefinedProp == null },
    { test : null,             result: null             == null },
    { test : false,            result: false            == null },
    { test : 0,                result: 0                == null },
    { test : '',               result: ''               == null },
    { test : '0',              result: '0'              == null },
]);

in case a restriction already exists with its default name:

-- Drop existing default constraint on Employee.CityBorn
DECLARE @default_name varchar(256);
SELECT @default_name = [name] FROM sys.default_constraints WHERE parent_object_id=OBJECT_ID('Employee') AND COL_NAME(parent_object_id, parent_column_id)='CityBorn';
EXEC('ALTER TABLE Employee DROP CONSTRAINT ' + @default_name);

-- Add default constraint on Employee.CityBorn
ALTER TABLE Employee ADD CONSTRAINT df_employee_1 DEFAULT 'SANDNES' FOR CityBorn;

Putting an answer , as my reputation aint enough to comment. But dont look at this as an answer, just a additional info, as myself, had some problems with both footer, and positioning.

When setting up the page, so that my footer always stays at the bottom, with position absolute, and main container/wrapper with relative position.

I then found some issues with my text content, and a menu inside the same content(white part of page between header and footer), when setting these to absolute, footer no longer stays down.

Postitioning is, as you say a complex theme.

My solution, to the content I wanted in 'absolute' positon in my webpage, and not be pushed to the side, when in example opening a drop down menu, was to actually give it postition relative, and putting it 35em below my drop down menu. (35em is the heigth of my dropdown menu, when fully extended)

Then, Top:-35em, for the content that before was pushed to the side. And then adding margin-bottom:-35em. This way, the content is "below" my drop down menu, but visually it is side by side with my drop down menu! And the white space below down to the footer, is with only 10em margin, as it was before starting to play around with this. So my solution to this was like this :

 html, body {
    margin:0;
    padding:0;
    height:100%;

}
h1 {
    margin:0;
}
    #webpage {
    position:relative;
    min-height:100%;
    margin:0;
    overflow:auto;
}
     #header {
    height:5em;
    width:100%;
    padding:0;
    margin:0;
}
     #text {
    position:relative;
   margin-bottom:-32em;
    padding-top:2em;
    padding-right:2em;
    padding-bottom:10em;
    background-repeat:no-repeat;
    width:70%;
    padding-left:auto;
    margin-left:auto;
    margin-right:auto;
    right:10em;
    float:right;
    top:-32em;
      }
#dropdown {

position:absolute;
    left:0;
    width:20%;
    clear:both;
    display:block;
    position:relative;
    top:1em;
    height:35em;

}
    #footer {
    position:absolute;
    width:100%;
    right:0;
    bottom:0;
    height:5em;
    margin:0;
     margin-top:5em;
}

I see your question is answered good, but after alot of troubleing I found this to be a very good solution, and a way to understand better how positioning works.. When I place my text content, below my drop down menu, it doesn't push my text to the side. If I changed the text to position absolute, the footer did not stay in place. As I can believe this is an issue for more people then me, I add this here. What in fact happends, is I put the text, 35ems, below my drop down.

Then, I visually put it right next to eachother, with relative position, and top:-35em;, and evening out the huge space below, with margin:-35em;

negative values are underestimated at times, very good functionality, when one understands these positions better!

Natually, fixed position, also seemed logic for my footer, but I do really want the footer to go below the viewport, if the text, or content, is longer than the viewport. And to stay at the bottom, if there is little content on the page.

This setupp fixed that very nicely, and remember to use 'em', not 'px' for a more fluid/dynamic page layout! :)

(there may be better solutions, but this works for me cross platforms, as well as devices).

Use int() on a boolean test:

x = int(x == 'true')

int() turns the boolean into 1 or 0. Note that any value not equal to 'true' will result in 0 being returned.

For a similar effect to form's target attribute, you can also use the formtarget attribute of input[type="submit]" or button[type="submit"].

From MDN:

...this attribute is a name or keyword indicating where to display the response that is received after submitting the form. This is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). If this attribute is specified, it overrides the target attribute of the elements's form owner. The following keywords have special meanings:

• _self: Load the response into the same browsing context as the current one. This value is the default if the attribute is not specified.
• _blank: Load the response into a new unnamed browsing context.
• _parent: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
• _top: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.

printStackTrace() helps the programmer to understand where the actual problem occurred. printStacktrace() is a method of the class Throwable of java.lang package. It prints several lines in the output console. The first line consists of several strings. It contains the name of the Throwable sub-class & the package information. From second line onwards, it describes the error position/line number beginning with at.

The last line always describes the destination affected by the error/exception. The second last line informs us about the next line in the stack where the control goes after getting transfer from the line number described in the last line. The errors/exceptions represents the output in the form a stack, which were fed into the stack by fillInStackTrace() method of Throwable class, which itself fills in the program control transfer details into the execution stack. The lines starting with at, are nothing but the values of the execution stack. In this way the programmer can understand where in code the actual problem is.

Along with the printStackTrace() method, it's a good idea to use e.getmessage().

Go to Android Manifest.xml and be sure to add the <uses-permission tag > inside the manifest tag but Outside of all other tags..

<manifest xlmns:android...>

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

This is an example of the permission of using Internet.

Pass Today as value as mentioned below in $viewQuery property :

$web = Get-SPWeb "http://sitename"
$list = $web.Lists.TryGetList($listtitle)

your syntax is completely wrong....you need to give findelement to the driver

i.e your code will be :

WebDriver driver = new FirefoxDriver();
WebeElement element ;

element = driver.findElement(By.xpath("//[@test-id='test-username']"); 

// your xpath is: "//[@test-id='test-username']"

i suggest try this :"//*[@test-id='test-username']"

Another solution:

select * from traintable
where (train, time) in (select train, max(time) from traintable group by train);

kubectl exec -it POD_NAME -c CONTAINER_NAME bash - then kill 1

Assuming the container is run as root which is not recommended.

In my case when I changed the application config, I had to reboot the container which was used in a sidecar pattern, I would kill the PID for the spring boot application which is owned by the docker user.

Here are the steps-

1. Download openssl from Google code (If you have a 64 bit machine you must download openssl-0.9.8e X64 not the latest version)

2. Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here.

3. detect debug.keystore file path. If u didn't find, then do a search in C:/ and use the Path in the command in next step.

4. detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line-

   $ keytool -exportcert -alias androiddebugkey -keystore "C:\Documents and Settings\Administrator.android\debug.keystore" | "C:\OpenSSL\bin\openssl" sha1 -binary |"C:\OpenSSL\bin\openssl" base64

   • it will ask for password, put android
   • that's all. u will get a key-hash

io.js has an exit and a beforeExit event, which do what you want.

ideally we should never catch Error in our Java application as it is an abnormal condition. The application would be in abnormal state and could result in carshing or giving some seriously wrong result.

This works in all browsers:

window.location.href = '...';

If you wanted to change the page without it reflecting in the browser back history, you can do:

window.location.replace('...');

You define the dependent module inside the setup.py of your own package with the "install_requires" option.

If your package needs to have some console script generated then you can use the "console_scripts" entry point in order to generate a wrapper script that will be placed within the 'bin' folder (e.g. of your virtualenv environment).

If you will look at package.json file.

you will see something like this

 "start": "http-server -a localhost -p 8000"

This tells start a http-server at address of localhost on port 8000

http-server is a node-module.

Update:- Including comment by @Usman, ideally it should be present in your package.json but if it's not present you can include it in scripts section.

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

It is very difficult to measure the speed of software programs, and when we try, the answers can be very complex and filled with exceptions and special cases. This is a big problem, because all those exceptions and special cases are distracting and unhelpful when we want to compare two different programs with one another to find out which is "fastest".

As a result of all this unhelpful complexity, people try to describe the speed of software programs using the smallest and least complex (mathematical) expressions possible. These expressions are very very crude approximations: Although, with a bit of luck, they will capture the "essence" of whether a piece of software is fast or slow.

Because they are approximations, we use the letter "O" (Big Oh) in the expression, as a convention to signal to the reader that we are making a gross oversimplification. (And to make sure that nobody mistakenly thinks that the expression is in any way accurate).

If you read the "Oh" as meaning "on the order of" or "approximately" you will not go too far wrong. (I think the choice of the Big-Oh might have been an attempt at humour).

The only thing that these "Big-Oh" expressions try to do is to describe how much the software slows down as we increase the amount of data that the software has to process. If we double the amount of data that needs to be processed, does the software need twice as long to finish it's work? Ten times as long? In practice, there are a very limited number of big-Oh expressions that you will encounter and need to worry about:

The good:

• O(1) Constant: The program takes the same time to run no matter how big the input is.
• O(log n) Logarithmic: The program run-time increases only slowly, even with big increases in the size of the input.

The bad:

• O(n) Linear: The program run-time increases proportionally to the size of the input.
• O(n^k) Polynomial: - Processing time grows faster and faster - as a polynomial function - as the size of the input increases.

... and the ugly:

• O(k^n) Exponential The program run-time increases very quickly with even moderate increases in the size of the problem - it is only practical to process small data sets with exponential algorithms.
• O(n!) Factorial The program run-time will be longer than you can afford to wait for anything but the very smallest and most trivial-seeming datasets.

install these ==>> pip install -U scikit-learn scipy matplotlib if still getting the same error then , make sure that your imoprted statment should be correct. i made the mistike while writing ensemble so ,(check spelling) its should be >>> from sklearn.ensemble import RandomForestClassifier

You have to indent the docstring after the function definition there (line 3, 4):

def print_lol(the_list):
"""this doesn't works"""
    print 'Ain't happening'

Indented:

def print_lol(the_list):
    """this works!"""
    print 'Aaaand it's happening'

Or you can use # to comment instead:

def print_lol(the_list):
#this works, too!
    print 'Hohoho'

Also, you can see PEP 257 about docstrings.

Hope this helps!

The simple answer is that arrays are ALWAYS passed by reference and the int arg[] simply lets the compiler know to expect an array

Mongoose Models inherit from Documents, which have a toObject() method. I believe what you're looking for should be the result of doc.toObject().

A nice way to achieve something like optional parameters is to use variadic args. The function actually receives a slice of whatever type you specify.

func foo(params ...int) {
    fmt.Println(len(params))
}

func main() {
    foo()
    foo(1)
    foo(1,2,3)
}

Here is a solution that looks good under iOS6/7/8/9.

Thanks for all your support, this is now on CocoaPods/Carthage/SPM at https://github.com/fulldecent/FDTextFieldTableViewCell

Basically we take the stock UITableViewCellStyleValue1 and staple a UITextField where the detailTextLabel is supposed to be. This gives us automatic placement for all scenarios: iOS6/7/8/9, iPhone/iPad, Image/No-image, Accessory/No-accessory, Portrait/Landscape, 1x/2x/3x.

Note: this is using storyboard with a UITableViewCellStyleValue1 type cell named "word".

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    cell = [tableView dequeueReusableCellWithIdentifier:@"word"];
    cell.detailTextLabel.hidden = YES;
    [[cell viewWithTag:3] removeFromSuperview];
    textField = [[UITextField alloc] init];
    textField.tag = 3;
    textField.translatesAutoresizingMaskIntoConstraints = NO;
    [cell.contentView addSubview:textField];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeLeading relatedBy:NSLayoutRelationEqual toItem:cell.textLabel attribute:NSLayoutAttributeTrailing multiplier:1 constant:8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:cell.contentView attribute:NSLayoutAttributeTop multiplier:1 constant:8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:cell.contentView attribute:NSLayoutAttributeBottom multiplier:1 constant:-8]];
    [cell addConstraint:[NSLayoutConstraint constraintWithItem:textField attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationEqual toItem:cell.detailTextLabel attribute:NSLayoutAttributeTrailing multiplier:1 constant:0]];
    textField.textAlignment = NSTextAlignmentRight;
    textField.delegate = self;
    return cell;
}

Okay, the .NET 2.0 answers:

If you don't need to clone the values, you can use the constructor overload to Dictionary which takes an existing IDictionary. (You can specify the comparer as the existing dictionary's comparer, too.)

If you do need to clone the values, you can use something like this:

public static Dictionary<TKey, TValue> CloneDictionaryCloningValues<TKey, TValue>
   (Dictionary<TKey, TValue> original) where TValue : ICloneable
{
    Dictionary<TKey, TValue> ret = new Dictionary<TKey, TValue>(original.Count,
                                                            original.Comparer);
    foreach (KeyValuePair<TKey, TValue> entry in original)
    {
        ret.Add(entry.Key, (TValue) entry.Value.Clone());
    }
    return ret;
}

That relies on TValue.Clone() being a suitably deep clone as well, of course.

According to the UI dialog documentation, the dialog plugin generates something like this:

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   </div>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

Can someone help me with the exact syntax?

It's a three-step process, and it involves modifying the openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way.

Find your openssl.cnf file. It is likely located in /usr/lib/ssl/openssl.cnf:

$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf

On my Debian system, /usr/lib/ssl/openssl.cnf is used by the built-in openssl program. On recent Debian systems it is located at /etc/ssl/openssl.cnf

You can determine which openssl.cnf is being used by adding a spurious XXX to the file and see if openssl chokes.

First, modify the req parameters. Add an alternate_names section to openssl.cnf with the names you want to use. There are no existing alternate_names sections, so it does not matter where you add it.

[ alternate_names ]

DNS.1        = example.com
DNS.2        = www.example.com
DNS.3        = mail.example.com
DNS.4        = ftp.example.com

Next, add the following to the existing [ v3_ca ] section. Search for the exact string [ v3_ca ]:

subjectAltName      = @alternate_names

You might change keyUsage to the following under [ v3_ca ]:

keyUsage = digitalSignature, keyEncipherment

digitalSignature and keyEncipherment are standard fare for a server certificate. Don't worry about nonRepudiation. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.

In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.

Second, modify the signing parameters. Find this line under the CA_default section:

# Extension copying option: use with caution.
# copy_extensions = copy

And change it to:

# Extension copying option: use with caution.
copy_extensions = copy

This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.

Third, generate your self-signed certificate:

$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...

Finally, examine the certificate:

$ openssl x509 -in certificate.pem -text -noout

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

With small custom synchronization context, sync function can wait for completion of async function, without creating deadlock. Here is small example for WinForms app.

Informally

entropy is availability of information or knowledge, Lack of information will leads to difficulties in prediction of future which is high entropy (next word prediction in text mining) and availability of information/knowledge will help us more realistic prediction of future (low entropy).

Relevant information of any type will reduce entropy and helps us predict more realistic future, that information can be word "meat" is present in sentence or word "meat" is not present. This is called Information Gain

Formally

entropy is lack of order of predicability

None of the answers are particularly satisfactory, so here's a small snippet to help.

            self.line_map.append(seekable.tell())

    def __getitem__(self, index):
        # NOTE: This assumes that you're not reading the file sequentially.  
        # For that, just use 'for line in file'.
        self.fin.seek(self.line_map[index])
        return self.fin.readline()

Example usage:

In: !cat /tmp/test.txt

Out:
Line zero.
Line one!

Line three.
End of file, line four.

In:
with open("/tmp/test.txt", 'rt') as fin:
    seeker = LineSeekableFile(fin)    
    print(seeker[1])
Out:
Line one!

This involves doing a lot of file seeks, but is useful for the cases where you can't fit the whole file in memory. It does one initial read to get the line locations (so it does read the whole file, but doesn't keep it all in memory), and then each access does a file seek after the fact.

You can calculate with Dates.

var birthdate = new Date("1990/1/1");
var cur = new Date();
var diff = cur-birthdate; // This is the difference in milliseconds
var age = Math.floor(diff/31557600000); // Divide by 1000*60*60*24*365.25

Per Martin Konicek's comment, to fully disable the selection of the items in the simplest manner:

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="Focusable" Value="false"/>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

However if you still require the functionality of the ListView, like being able to select an item, then you can visually disable the styling of the selected item like so:

You can do this a number of ways, from changing the ListViewItem's ControlTemplate to just setting a style (much easier). You can create a style for the ListViewItems using the ItemContainerStyle and 'turn off' the background and border brush when it is selected.

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsSelected"
                         Value="True">
                    <Setter Property="Background"
                            Value="{x:Null}" />
                    <Setter Property="BorderBrush"
                            Value="{x:Null}" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

Also, unless you have some other way of notifying the user when the item is selected (or just for testing) you can add a column to represent the value:

<GridViewColumn Header="IsSelected"
                DisplayMemberBinding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem}}, Path=IsSelected}" />

UPDATE: This has been fixed in jQuery 3.x. If you have no possibility to upgrade to any version above 3.0, you could use following snippet BUT be aware that now you will lose sync behaviour of script loading in the targeted content.

You could fix it, setting explicitly async option of xhr request to true:

$.ajaxPrefilter(function( options, original_Options, jqXHR ) {
    options.async = true;
});

This will be inside a function or script tag with custom CSS with classname as Custom

 var board = document.createElement('div');
 board.className = "Custom";
 board.innerHTML = "your data";
 console.log(count);
 document.getElementById('notification').appendChild(board);

The most common cause of this problem is that Matlab cannot find the file on it's search path. Basically, Matlab looks for files in:

1. The current directory (pwd);
2. Directly in a directory on the path (to see the path, type path at the command line)
3. In a directory named @(whatever the class of the first argument is) that is in any directory above.
   
   

   As someone else suggested, you can use the command which, but that is often unhelpful in this case - it tells you Matlab can't find the file, which you knew already.
   
   So the first thing to do is make sure the file is locatable on the path.
   

   Next thing to do is make sure that the file that matlab is finding (use which) requires the same type as the first argument you are actually passing. I.el, If w is supposed to be different class, and there is a divrat function there, but w is actually empty, [], so matlab is looking for Double/divrat, when there is only a @(yourclass)/divrat. This is just speculation on my part, but this often bites me.

Try putting display: block in the <li> tags instead of the <ul>

Try removing the uses-sdk part form AndroidManifest.xml file. it worked for me!

Don't use the Android Virtual Device with too low configuration. Let it be medium.

From the npm-link documentation:

In the local module directory:

$ cd ./package-dir
$ npm link

In the directory of the project to use the module:

$ cd ./project-dir
$ npm link package-name

Or in one go using relative paths:

$ cd ./project-dir
$ npm link ../package-dir

This is equivalent to using two commands above under the hood.

In Rails 3.1, you should use the query interface:

• new(attributes)
• create(attributes)
• create!(attributes)
• find(id_or_array)
• destroy(id_or_array)
• destroy_all
• delete(id_or_array)
• delete_all
• update(ids, updates)
• update_all(updates)
• exists?

update and update_all are the operation you need.

See details here: http://m.onkey.org/active-record-query-interface

This one works for me...

new System.Uri(Page.Request.Url, ResolveClientUrl("~/mypage.aspx")).AbsoluteUri

The enumerate function returns a generator object which, at each iteration, yields a tuple containing the index of the element (i), numbered starting from 0 by default, coupled with the element itself (a), and the for loop conveniently allows you to access both fields of those generated tuples and assign variable names to them.

__FILE__ use examples based on localhost server results:

echo __FILE__;
// C:\LocalServer\www\templates\page.php

echo strrchr( __FILE__ , '\\' );
// \page.php

echo substr( strrchr( __FILE__ , '\\' ), 1);
// page.php

echo basename(__FILE__, '.php');
// page

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

You need to use kill -9 59780 with 59780 replaced with found PID number (use lsof -wni tcp:3000 to see which process used 3000 port and get the process PID).

Or you can just modify your puma config change the tcp port tcp://127.0.0.1:3000 from 3000 to 9292 or other port that not been used.

Or you can start your rails app by using:

bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001

Both Null and undefined in JavaScript indicate absence of value.

var a = null; //variable assigned null value
var b;  // undefined

Despite the fact both exist for absence of value but: Undefined actually means the variable is not initialized. Functions that return nothing and function parameters for which no value is supplied, undefined value is returned. Use strict equality operator === to distinguish between null and undefined.

Reference: http://www.thesstech.com/javascript/null-and-undefined

Check if your scripts name doesn't contain $SERVICE. If it does, it will be shown in ps results, causing script to always think that service is running. You can grep it against current filename like this:

#!/bin/sh
SERVICE=$1
if ps ax | grep -v grep | grep -v $0 | grep $SERVICE > /dev/null
then
    echo "$SERVICE service running, everything is fine"
else
    echo "$SERVICE is not running"

The VBA script below looks for all unique values from cell B5 all the way down to the very last cell in column B… $B$1048576. Once it is found, they are stored in the array (objDict).

Private Const SHT_MASTER = “MASTER”
Private Const SHT_INST_INDEX = “InstrumentIndex”

Sub UniqueList()
    Dim Xyber
    Dim objDict As Object
    Dim lngRow As Long

    Sheets(SHT_MASTER).Activate
    Xyber = Application.Transpose(Sheets(SHT_MASTER).Range([b5], Cells(Rows.count, “B”).End(xlUp)))
    Sheets(SHT_INST_INDEX).Activate
    Set objDict = CreateObject(“Scripting.Dictionary”)
    For lngRow = 1 To UBound(Xyber, 1)
    If Len(Xyber(lngRow)) > 0 Then objDict(Xyber(lngRow)) = 1
    Next
    Sheets(SHT_INST_INDEX).Range(“B1:B” & objDict.count) = Application.Transpose(objDict.keys)
End Sub

I have tested and documented with some screenshots of the this solution. Here is the link where you can find it....

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

I'm using Bootstrap 4 and Dennis Puzak's solution does not work for me.

The next solution works for me

.form-control::placeholder { color: white;} /* Chrome, Firefox, Opera*/
:-ms-input-placeholder.form-control { color: white; }  /* Internet Explorer*/
.form-control::-ms-input-placeholder { color: white; }  /* Microsoft Edge*/

On the flip side, I was having an issue with PHPUNIT asserting urls was contained in or equal to a url that was json_encoded -

my expected:

http://localhost/api/v1/admin/logs/testLog.log

would be encoded to:

http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log

If you need to do a comparison, transforming the url using:

addcslashes($url, '/')

allowed for the proper output during my comparisons.

If you haven't committed changes

If your changes are compatible with the other branch

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.

As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:

git checkout -b branch_name
git add <files>
git commit -m "message"

If your changes are incompatible with the other branch

If you get the error:

error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches

Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:

git stash
git checkout -b branch_name
git stash pop

It will be as if you had made those changes after creating the new branch. Then you can commit as usual:

git add <files>
git commit -m "message"

If you have committed changes

If you want to keep the commits in the original branch

See the answer by Carl Norum with cherry-picking, which is the right tool in this case:

git checkout <target name>
git cherry-pick <original branch>

If you don't want to keep the commits in the original branch

See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:

git branch -f <original branch> <earlier commit id>

If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

Iknow It is too old to answer, but I couldn't find solution like this.

Use

python -V

or

python --version

NOTE: Please note that the "V" in the python -V command is capital V. python -v (small "v") will launch Python in verbose mode.

There is a second parameter for the callback for collection.insert that will return the doc or docs inserted, which should have _ids.

Try:

collection.insert(objectToInsert, function(err,docsInserted){
    console.log(docsInserted);
});

and check the console to see what I mean.

Another solution is to use a Predicate, then you can use this in any filter:

public static <T> Predicate<T> distinctBy(Function<? super T, ?> f) {
  Set<Object> objects = new ConcurrentHashSet<>();
  return t -> objects.add(f.apply(t));
}

Then simply reuse the predicate anywhere:

employees.stream().filter(distinctBy(e -> e.getId));

Note: in the JavaDoc of filter, which says it takes a stateless Predicte. Actually, this works fine even if the stream is parallel.

About other solutions:

1) Using .collect(Collectors.toConcurrentMap(..)).values() is a good solution, but it's annoying if you want to sort and keep the order.

2) stream.removeIf(e->!seen.add(e.getID())); is also another very good solution. But we need to make sure the collection implemented removeIf, for example it will throw exception if we construct the collection use Arrays.asList(..).

This will show the value up to two decimal places after the dot.

#include <iostream>
#include <iomanip>

double d = 2.0;
int n = 2;
cout << fixed << setprecision(n) << d;

See here: Fixed-point notation

std::fixed

Use fixed floating-point notation Sets the floatfield format flag for the str stream to fixed.

When floatfield is set to fixed, floating-point values are written using fixed-point notation: the value is represented with exactly as many digits in the decimal part as specified by the precision field (precision) and with no exponent part.

std::setprecision

Set decimal precision Sets the decimal precision to be used to format floating-point values on output operations.

If you're familiar with the IEEE standard for representing the floating-points, you would know that it is impossible to show floating-points with full-precision out of the scope of the standard, that is to say, it will always result in a rounding of the real value.

You need to first check whether the value is within the scope, if yes, then use:

cout << defaultfloat << d ;

std::defaultfloat

Use default floating-point notation Sets the floatfield format flag for the str stream to defaultfloat.

When floatfield is set to defaultfloat, floating-point values are written using the default notation: the representation uses as many meaningful digits as needed up to the stream's decimal precision (precision), counting both the digits before and after the decimal point (if any).

That is also the default behavior of cout, which means you don't use it explicitly.

You can also use one line to do that:

{{ yourVariable is not defined ? "Not Assigned" : "Assigned" }}

If you want to just uncommit the last commit use this:

git reset HEAD~

work like charm for me.

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

I had the exact same error message, and tried the suggested solutions in this thread but without success.

what solved the problem for me is opening the .xlsx file and saving it as .xls (excel 2003) file.

maybe the file was corrupted or in a different format, and saving it again fixed it.

From the output of java -X:

    -Xloggc:<file>    log GC status to a file with time stamps

Documented here:

-Xloggc:filename

Sets the file to which verbose GC events information should be redirected for logging. The information written to this file is similar to the output of -verbose:gc with the time elapsed since the first GC event preceding each logged event. The -Xloggc option overrides -verbose:gc if both are given with the same java command.

Example:

    -Xloggc:garbage-collection.log

So the output looks something like this:

0.590: [GC 896K->278K(5056K), 0.0096650 secs]
0.906: [GC 1174K->774K(5056K), 0.0106856 secs]
1.320: [GC 1670K->1009K(5056K), 0.0101132 secs]
1.459: [GC 1902K->1055K(5056K), 0.0030196 secs]
1.600: [GC 1951K->1161K(5056K), 0.0032375 secs]
1.686: [GC 1805K->1238K(5056K), 0.0034732 secs]
1.690: [Full GC 1238K->1238K(5056K), 0.0631661 secs]
1.874: [GC 62133K->61257K(65060K), 0.0014464 secs]

step 1 : create layout with name activity_main.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    tools:context=".MainActivity"
    android:background="#c6cabd"
    >
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dp"
        android:textColor="#ff0e13"
        />
    <EditText
        android:id="@+id/et"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv"
        android:hint="Input your country"
        />
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Get EditText Text"
        android:layout_below="@id/et"
        />
</RelativeLayout>

Step 2 : Create class Main.class

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.btn);
        final TextView tv = (TextView) findViewById(R.id.tv);
        final EditText et = (EditText) findViewById(R.id.et);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String country = et.getText().toString();
                tv.setText("Your inputted country is : " + country);
            }
        });
 }
}

Brant's solution is absolutely correct, but I needed to modify it to make it work with multiple select checkboxes and commit=false. Here is my solution:

models.py

class Choices(models.Model):
    description = models.CharField(max_length=300)

class Profile(models.Model):
   user = models.ForeignKey(User, blank=True, unique=True, verbose_name_('user'))
   the_choices = models.ManyToManyField(Choices)

forms.py

class ProfileForm(forms.ModelForm):
    the_choices = forms.ModelMultipleChoiceField(queryset=Choices.objects.all(), required=False, widget=forms.CheckboxSelectMultiple)

    class Meta:
        model = Profile
        exclude = ['user']

views.py

if request.method=='POST':
    form = ProfileForm(request.POST)
    if form.is_valid():
        profile = form.save(commit=False)
        profile.user = request.user
        profile.save()
        form.save_m2m() # needed since using commit=False
    else:
        form = ProfileForm()

return render_to_response(template_name, {"profile_form": form}, context_instance=RequestContext(request))

Just keep the following in mind.

In IIS if you have a folder for example called Pages with multiple websites in it. Website will inherit settings from the web.config file from the parent directory. So even if the folder page (in this example Pages) isn't a website but contains a web.config file, all websites listed inside of it will inherit the setting.

For GNU/Linux & MacOS (or generally UNIX like) systems, I've used below method which works fine:

private int tryGetPid(Process process)
{
    if (process.getClass().getName().equals("java.lang.UNIXProcess"))
    {
        try
        {
            Field f = process.getClass().getDeclaredField("pid");
            f.setAccessible(true);
            return f.getInt(process);
        }
        catch (IllegalAccessException | IllegalArgumentException | NoSuchFieldException | SecurityException e)
        {
        }
    }

    return 0;
}

You can use a timedelta object:

from datetime import datetime, timedelta
    
d = datetime.today() - timedelta(days=days_to_subtract)

I use ssh to connect to remote server and have python code execute cv2.VideoCapture(0) to capture remote webcam, then encounter this error message:

error: (-215)size.width>0 && size.height>0 in function imshow

Finally, I have to grant access to /dev/video0 (which is my webcam device) with my user account and the error message was gone. Use usermod to add user into group video

usermod -a -G video user

you can easily find the current CodeIgniter version by

echo CI_VERSION 


or you can navigate to System->core->codeigniter.php file and you can see the constant

/**

 *
 * @var string
 *
 */
    const CI_VERSION = '3.1.6';

TL;DR: List.stream().forEach() was the fastest.

I felt I should add my results from benchmarking iteration. I took a very simple approach (no benchmarking frameworks) and benchmarked 5 different methods:

1. classic for
2. classic foreach
3. List.forEach()
4. List.stream().forEach()
5. List.parallelStream().forEach

the testing procedure and parameters

private List<Integer> list;
private final int size = 1_000_000;

public MyClass(){
    list = new ArrayList<>();
    Random rand = new Random();
    for (int i = 0; i < size; ++i) {
        list.add(rand.nextInt(size * 50));
    }    
}
private void doIt(Integer i) {
    i *= 2; //so it won't get JITed out
}

The list in this class shall be iterated over and have some doIt(Integer i) applied to all it's members, each time via a different method. in the Main class I run the tested method three times to warm up the JVM. I then run the test method 1000 times summing the time it takes for each iteration method (using System.nanoTime()). After that's done i divide that sum by 1000 and that's the result, average time. example:

myClass.fored();
myClass.fored();
myClass.fored();
for (int i = 0; i < reps; ++i) {
    begin = System.nanoTime();
    myClass.fored();
    end = System.nanoTime();
    nanoSum += end - begin;
}
System.out.println(nanoSum / reps);

I ran this on a i5 4 core CPU, with java version 1.8.0_05

classic for

for(int i = 0, l = list.size(); i < l; ++i) {
    doIt(list.get(i));
}

execution time: 4.21 ms

classic foreach

for(Integer i : list) {
    doIt(i);
}

execution time: 5.95 ms

List.forEach()

list.forEach((i) -> doIt(i));

execution time: 3.11 ms

List.stream().forEach()

list.stream().forEach((i) -> doIt(i));

execution time: 2.79 ms

List.parallelStream().forEach

list.parallelStream().forEach((i) -> doIt(i));

execution time: 3.6 ms

This should get the id added.

ASP.NET MVC 5 and lower:

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))
   { } %>

ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id.

<form asp-controller="Account" asp-action="Register" method="post" id="signupform" role="form"></form>

Download commons-net binary from here. Extract the files and reference the commons-net-x.x.jar file.

The csv file might contain very huge fields, therefore increase the field_size_limit:

import sys
import csv

csv.field_size_limit(sys.maxsize)

sys.maxsize works for Python 2.x and 3.x. sys.maxint would only work with Python 2.x (SO: what-is-sys-maxint-in-python-3)

Update

As Geoff pointed out, the code above might result in the following error: OverflowError: Python int too large to convert to C long. To circumvent this, you could use the following quick and dirty code (which should work on every system with Python 2 and Python 3):

import sys
import csv
maxInt = sys.maxsize

while True:
    # decrease the maxInt value by factor 10 
    # as long as the OverflowError occurs.

    try:
        csv.field_size_limit(maxInt)
        break
    except OverflowError:
        maxInt = int(maxInt/10)

Our version of Oracle is running on Red Hat Enterprise Linux. We experimented with several different types of group permissions to no avail. The /defaultdir directory had a group that was a secondary group for the oracle user. When we updated the /defaultdir directory to have a group of "oinstall" (oracle's primary group), I was able to select from the external tables underneath that directory with no problem.

So, for others that come along and might have this issue, make the directory have oracle's primary group as the group and it might resolve it for you as it did us. We were able to set the permissions to 770 on the directory and files and selecting on the external tables works fine now.

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

The second method would almost certainly be the fastest way to test whether a null-terminated string is empty, since it involves one read and one comparison. There's certainly nothing wrong with this approach in this case, so you may as well use it.

The third method doesn't check whether a character array is empty; it ensures that a character array is empty.

For Spring Boot 2.1.0 and later you can use

mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar

Java SE 6 or Java EE 5 provides a method to do this now so there is no need for extra libraries.

The method is DatatypeConverter.parseHexBinary

In this case it can be used as follows:

String str = "9B7D2C34A366BF890C730641E6CECF6F";
byte[] bytes = DatatypeConverter.parseHexBinary(str);

The class also provides type conversions for many other formats that are generally used in XML.

Starting June 2019, with Windows 10, you won't have to change the codepage.

See "Introducing Windows Terminal" (from Kayla Cinnamon) and the Microsoft/Terminal.
Through the use of the Consolas font, partial Unicode support will be provided.

As documented in Microsoft/Terminal issue 387:

There are 87,887 ideographs currently in Unicode. You need all of them too?
We need a boundary, and characters beyond that boundary should be handled by font fallback / font linking / whatever.

What Consolas should cover:

• Characters that used as symbols that used by modern OSS programs in CLI.
• These characters should follow Consolas' design and metrics, and properly aligned with existing Consolas characters.

What Consolas should NOT cover:

• Characters and punctuation of scripts that beyond Latin, Greek and Cyrillic, especially characters need complex shaping (like Arabic).
• These characters should be handled with font fallback.

    public Dictionary<string, object> ToDictionary<T>(string key, T value)
    {
        try
        {
            var payload = new Dictionary<string, object>
            {
                { key, value }
            }; 
        } catch (Exception e)
        {
            return null;
        }
    }

    public T FromDictionary<T>(Dictionary<string, object> payload, string key)
    {
        try
        {
            JObject jObject = (JObject) payload[key];
            T t = jObject.ToObject<T>();
            return (t);
        }
        catch(Exception e) {
            return default(T);
        }
    }

If you are getting the output Optional(5) when trying to print the value of 5 in an optional Int or String, you should unwrap the value first:

if value != nil
{ print(value)
}

or you can use this:

if let value = text {
    print(value)
}

or in simple just 1 line answer:

print(value ?? "")

The last line will check if variable 'value' has any value assigned to it, if not it will print empty string

remove_indices = [1,2,3]
somelist = [i for j, i in enumerate(somelist) if j not in remove_indices]

Example:

In [9]: remove_indices = [1,2,3]

In [10]: somelist = range(10)

In [11]: somelist = [i for j, i in enumerate(somelist) if j not in remove_indices]

In [12]: somelist
Out[12]: [0, 4, 5, 6, 7, 8, 9]

As mentioned above, you need the autoreload extension. If you want it to automatically start every time you launch ipython, you need to add it to the ipython_config.py startup file:

It may be necessary to generate one first:

ipython profile create

Then include these lines in ~/.ipython/profile_default/ipython_config.py:

c.InteractiveShellApp.exec_lines = []
c.InteractiveShellApp.exec_lines.append('%load_ext autoreload')
c.InteractiveShellApp.exec_lines.append('%autoreload 2')

As well as an optional warning in case you need to take advantage of compiled Python code in .pyc files:

c.InteractiveShellApp.exec_lines.append('print "Warning: disable autoreload in ipython_config.py to improve performance." ')

edit: the above works with version 0.12.1 and 0.13

You can't. The CLR won't let you. A stack overflow is a fatal error and can't be recovered from.

First of all, there is no real folder concept in S3. You definitely can have a file @ '/folder/subfolder/myfile.txt' and no folder nor subfolder.

To "simulate" a folder in S3, you must create an empty file with a '/' at the end of its name (see Amazon S3 boto - how to create a folder?)

For your problem, you should probably use the method get_all_keys with the 2 parameters : prefix and delimiter

https://github.com/boto/boto/blob/develop/boto/s3/bucket.py#L427

for key in bucket.get_all_keys(prefix='first-level/', delimiter='/'):
    print(key.name)

$provide service

They are technically the same thing, it's actually a different notation of using the provider function of the $provide service.

• If you're using a class: you could use the service notation.
• If you're using an object: you could use the factory notation.

The only difference between the service and the factory notation is that the service is new-ed and the factory is not. But for everything else they both look, smell and behave the same. Again, it's just a shorthand for the $provide.provider function.

// Factory

angular.module('myApp').factory('myFactory', function() {

  var _myPrivateValue = 123;

  return {
    privateValue: function() { return _myPrivateValue; }
  };

});

// Service

function MyService() {
  this._myPrivateValue = 123;
}

MyService.prototype.privateValue = function() {
  return this._myPrivateValue;
};

angular.module('myApp').service('MyService', MyService);

Having the same chore on windows 10, and windows server 2012. I found the following solution:

echo quit |sqlplus schemaName/schemaPassword@sid @plsqlScript.sql > outputFile.log

Explanation

echo quit | send the quit command to exit sqlplus after the script completes

sqlplus schemaName/schemaPassword@sid @plsqlScript.sql execute plssql script plsqlScript.sql in schema schemaName with password schemaPassword connecting to SID sid

> outputFile.log redirect sqlplus output to log file outputFile.log

These examples are from php.net. Thanks to you, I also just learned about the new php hashing functions.

Read the php documentation to find out about the possibilities and best practices: http://www.php.net/manual/en/function.password-hash.php

Save a password hash:

$options = [
    'cost' => 11,
];
// Get the password from post
$passwordFromPost = $_POST['password'];

$hash = password_hash($passwordFromPost, PASSWORD_BCRYPT, $options);

// Now insert it (with login or whatever) into your database, use mysqli or pdo!

Get the password hash:

// Get the password from the database and compare it to a variable (for example post)
$passwordFromPost = $_POST['password'];
$hashedPasswordFromDB = ...;

if (password_verify($passwordFromPost, $hashedPasswordFromDB)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}

I think the best solution with generics would be:

/* This for non primitive types */
public static <T> T[] concatenate (T[]... elements) {

    T[] C = null;
    for (T[] element: elements) {
        if (element==null) continue;
        if (C==null) C = (T[]) Array.newInstance(element.getClass().getComponentType(), element.length);
        else C = resizeArray(C, C.length+element.length);

        System.arraycopy(element, 0, C, C.length-element.length, element.length);
    }

    return C;
}

/**
 * as far as i know, primitive types do not accept generics 
 * http://stackoverflow.com/questions/2721546/why-dont-java-generics-support-primitive-types
 * for primitive types we could do something like this:

public static int[] concatenate (int[]... elements){
    int[] C = null;
    for (int[] element: elements) {
        if (element==null) continue;
        if (C==null) C = new int[element.length];
        else C = resizeArray(C, C.length+element.length);

        System.arraycopy(element, 0, C, C.length-element.length, element.length);
    }
    return C;
}

private static <T> T resizeArray (T array, int newSize) {
    int oldSize =
            java.lang.reflect.Array.getLength(array);
    Class elementType =
            array.getClass().getComponentType();
    Object newArray =
            java.lang.reflect.Array.newInstance(
                    elementType, newSize);
    int preserveLength = Math.min(oldSize, newSize);
    if (preserveLength > 0)
        System.arraycopy(array, 0,
                newArray, 0, preserveLength);
    return (T) newArray;
}

In my case ping works from device but not from the emulator. I found this documentation: http://developer.android.com/guide/developing/devices/emulator.html#emulatornetworking

On the topic of "Local Networking Limitations" it says:

"Depending on the environment, the emulator may not be able to support other protocols (such as ICMP, used for "ping") might not be supported. Currently, the emulator does not support IGMP or multicast."

Further information: http://groups.google.com/group/android-developers/browse_thread/thread/8657506be6819297

this is a known limitation of the QEMU user-mode network stack. Quoting from the original doc: Note that ping is not supported reliably to the internet as it would require root privileges. It means you can only ping the local router (10.0.2.2).

Why not just return the worksheet name with address = cell.Worksheet.Name then you can concatenate the address back on like this address = cell.Worksheet.Name & "!" & cell.Address

To link to a UNC path from an HTML document, use file:///// (yes, that's five slashes).

file://///server/path/to/file.txt

Note that this is most useful in IE and Outlook/Word. It won't work in Chrome or Firefox, intentionally - the link will fail silently. Some words from the Mozilla team:

For security purposes, Mozilla applications block links to local files (and directories) from remote files.

And less directly, from Google:

Firefox and Chrome doesn't open "file://" links from pages that originated from outside the local machine. This is a design decision made by those browsers to improve security.

The Mozilla article includes a set of client settings you can use to override this behavior in Firefox, and there are extensions for both browsers to override this restriction.

You can use parents() to get all parents with the given selector.

Description: Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.

But parent() will get just the first parent of the element.

Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.

jQuery parent() vs. parents()

And there is .parentsUntil() which I think will be the best.

Description: Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector.

I'm posting here hoping that others my find my answer helpful. I had a similar problem when I tried to do a stash pop on a different branch than the one I had stashed from. On my case I had no files that were uncommitted or in the index but still got into the merge conflicts case (same case as @pid). As others pointed out previously, the failed git stash pop did indeed retain my stash, then A quick git reset HEAD plus going back to my original branch and doing the stash from there did resolve my problem.

This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';

const root = document.getElementById('someElementIdHere');

ReactDOM.render(
  <Application />,
  root,
);

Your <Application /> component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router, redux, redux-saga, react-devtools come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.

When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about, you should create the route in whatever routing package you're using and create a component of About.js with whatever information you need.

Just do:

Stream.of(stream1, stream2, Stream.of(element)).flatMap(identity());

where identity() is a static import of Function.identity().

Concatenating multiple streams into one stream is the same as flattening a stream.

However, unfortunately, for some reason there is no flatten() method on Stream, so you have to use flatMap() with the identity function.

Replace false with 0

If additional table doesn't fit, you can write your own function for translation.

The plus of sql function over case is, that you can use it in various places, and keep translation logic in one place.

If you list the bakground-none class after the other classes, its properties will override those already set. There is no need to use !important here.

For example:

.red { background-color: red; }
.background-none { background: none; }

and

<a class="red background-none" href="#carousel">...</a>

The link will not have a red background. Please note that this only overrides properties that have a selector that is less or equally specific.

To verify the Python version for commands on Windows, run the following commands in a command prompt and verify the output

c:\>python -V
Python 2.7.16

c:\>py -2 -V
Python 2.7.16

c:\>py -3 -V
Python 3.7.3

Also, To see the folder configuration for each Python version, run the following commands:

For Python 2,'py -2 -m site'
For Python 3,'py -3 -m site'

Delete Without Rebooting

The OP's question indeed has been answered extensively, including how to avoid rebooting through powershell, vbscript, or you name it.

However, if you need to stick to cmd commands only and don't have the luxury of being able to call powershell or vbscript, you could use the following approach:

rem remove from current cmd instance
  SET FOOBAR=
rem remove from the registry if it's a user variable
  REG delete HKCU\Environment /F /V FOOBAR
rem remove from the registry if it's a system variable
  REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR
rem tell Explorer.exe to reload the environment from the registry
  SETX DUMMY ""
rem remove the dummy
  REG delete HKCU\Environment /F /V DUMMY

So the magic here is that by using "setx" to assign something to a variable you don't need (in my example DUMMY), you force Explorer.exe to reread the variables from the registry, without needing powershell. You then clean up that dummy, and even though that one will stay in Explorer's environment for a little while longer, it will probably not harm anyone.

Or if after deleting variables you need to set new ones, then you don't even need any dummy. Just using SETX to set the new variables will automatically clear the ones you just removed from any new cmd tasks that might get started.

Background information: I just used this approach successfully to replace a set of user variables by system variables of the same name on all of the computers at my job, by modifying an existing cmd script. There are too many computers to do it manually, nor was it practical to copy extra powershell or vbscripts to all of them. The reason I urgently needed to replace user with system variables was that user variables get synchronized in roaming profiles (didn't think about that), so multiple machines using the same windows login but needing different values, got mixed up.

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

var dataArray = [];
var obj = jQuery.parseJSON(yourInput);

$.each(obj, function (index, value) {
    dataArray.push([value["yourID"].toString(), value["yourValue"] ]);
});

this helps me a lot :-)

iconv(1)

iconv -f FROM-ENCODING -t TO-ENCODING file.txt

Also there are iconv-based tools in many languages.

This is how i solve my problem

let parameters = [
            "station_id" :        "1000",
            "title":      "Murat Akdeniz",
            "body":        "xxxxxx"]

let imgData = UIImageJPEGRepresentation(UIImage(named: "1.png")!,1)



    Alamofire.upload(
        multipartFormData: { MultipartFormData in
        //    multipartFormData.append(imageData, withName: "user", fileName: "user.jpg", mimeType: "image/jpeg")

            for (key, value) in parameters {
                MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }

        MultipartFormData.append(UIImageJPEGRepresentation(UIImage(named: "1.png")!, 1)!, withName: "photos[1]", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
        MultipartFormData.append(UIImageJPEGRepresentation(UIImage(named: "1.png")!, 1)!, withName: "photos[2]", fileName: "swift_file.jpeg", mimeType: "image/jpeg")


    }, to: "http://platform.twitone.com/station/add-feedback") { (result) in

        switch result {
        case .success(let upload, _, _):

            upload.responseJSON { response in
                print(response.result.value)
            }

        case .failure(let encodingError): break
            print(encodingError)
        }


    }

You can call sortable on a <tbody> instead of on the individual rows.

<table>
    <tbody>
        <tr> 
            <td>1</td>
            <td>2</td>
        </tr>
        <tr>
            <td>3</td>
            <td>4</td> 
        </tr>
        <tr>
            <td>5</td>
            <td>6</td>
        </tr>  
    </tbody>    
</table>?

<script>
    $('tbody').sortable();

  $( "tbody" ).sortable();_x000D_
});

</table>

select t.* from table t
    join (
        select C2, C3, C4
        from table
        group by C2, C3, C4
        having count(*) > 1
    ) t2
    using (C2, C3, C4);

You can also pad the characters left by including a number following the X, such as this: string.format("0x{0:X8}", string_to_modify), which yields "0x00000C20".

You can take the SelectedItem and cast it back to your class and access its properties.

 MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);

Edit You can try using DataTextField and DataValueField, I used it with DataSource.

ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";

I had the same problem, after delete some gradle files (of aws)

i solved it by mark them "ignore gradle"

I believe it is not the best answer but it solve it for me

Gradle (at the right bar)--> right click on the problematic gradle --> ignore

I was bored of this problem so I decided to create a shell script to restore my mongo data base easily.

#!/bin/sh
sudo rm /var/lib/mongodb/mongod.lock
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
sudo service mongodb start

use \t instead of space.

bw.write("\t"); 

The method is implicitly defined (i.e. generated by the compiler).

From the JLS:

In addition, if E is the name of an enum type, then that type has the following implicitly declared static methods:

/**
* Returns an array containing the constants of this enum 
* type, in the order they're declared.  This method may be
* used to iterate over the constants as follows:
*
*    for(E c : E.values())
*        System.out.println(c);
*
* @return an array containing the constants of this enum 
* type, in the order they're declared
*/
public static E[] values();

/**
* Returns the enum constant of this type with the specified
* name.
* The string must match exactly an identifier used to declare
* an enum constant in this type.  (Extraneous whitespace 
* characters are not permitted.)
* 
* @return the enum constant with the specified name
* @throws IllegalArgumentException if this enum type has no
* constant with the specified name
*/
public static E valueOf(String name);

Use: http://jsfiddle.net/xH79d/

var n = $("input[name^='card']").length;
var array = $("input[name^='card']");

for(i=0; i < n; i++) {

   // use .eq() within a jQuery object to navigate it by Index

   card_value = array.eq(i).attr('name'); // I'm assuming you wanted -name-
   // otherwise it'd be .eq(i).val(); (if you wanted the text value)
   alert(card_value);
}

?

What do you mean by "version number"? It is quite common to tag a commit with a version number and then use

$ git describe --tags

to identify the current HEAD w.r.t. any tags. If you mean you want to know the hash of the current HEAD, you probably want:

$ git rev-parse HEAD

or for the short revision hash:

$ git rev-parse --short HEAD

It is often sufficient to do:

$ cat .git/refs/heads/${branch-master}

but this is not reliable as the ref may be packed.

time_point objects only support arithmetic with other time_point or duration objects.

You'll need to convert your long to a duration of specified units, then your code should work correctly.

Alt+F4 is working only in brackets

SendKeys.SendWait("(%{F4})");
