JNZ     Jump if Not Zero    ZF=0

Indeed, this is confusing right.

To make it easier to understand, replace Not Zero with Not Set. (Please take note this is for your own understanding)

Hence,

JNZ     Jump if Not Set     ZF=0

Not Set means flag Z = 0. So Jump (Jump if Not Set)

Set means flag Z = 1. So, do NOT Jump

Two typical problems:

1. Missing the ProjectInstaller class (as @MiguelAngelo has pointed)
2. The command prompt must “Run as Administrator”

I love this piece of code, use it to load a file into one String:

File file = new File("/my/location");
String contents = new Scanner(file).useDelimiter("\\Z").next();

Here's a function to stringify timedelta.total_seconds(). It works in python 2 and 3.

def strf_interval(seconds):
    days, remainder = divmod(seconds, 86400)
    hours, remainder = divmod(remainder, 3600)
    minutes, seconds = divmod(remainder, 60)
    return '{} {} {} {}'.format(
            "" if int(days) == 0 else str(int(days)) + ' days',
            "" if int(hours) == 0 else str(int(hours)) + ' hours',
            "" if int(minutes) == 0 else str(int(minutes))  + ' mins',
            "" if int(seconds) == 0 else str(int(seconds))  + ' secs'
        )

Example output:

>>> print(strf_interval(1))
   1 secs
>>> print(strf_interval(100))
  1 mins 40 secs
>>> print(strf_interval(1000))
  16 mins 40 secs
>>> print(strf_interval(10000))
 2 hours 46 mins 40 secs
>>> print(strf_interval(100000))
1 days 3 hours 46 mins 40 secs

I agree that versioning the resource representation better follows the REST approach...but, one big problem with custom MIME types (or MIME types that append a version parameter) is the poor support to write to Accept and Content-Type headers in HTML and JavaScript.

For example, it is not possible IMO to POST with the following headers in HTML5 forms, in order to create a resource:

Accept: application/vnd.company.myapp-v3+json
Content-Type: application/vnd.company.myapp-v3+json 

This is because the HTML5 enctype attribute is an enumeration, therefore anything other than the usual application/x-www-formurlencoded, multipart/form-data and text/plain are invalid.

...nor am I sure it is supported across all browsers in HTML4 (which has a more lax encytpe attribute, but would be a browser implementation issue as to whether the MIME type was forwarded)

Because of this I now feel the most appropriate way to version is via the URI, but I accept that it is not the 'correct' way.

Check this code. It awesome code for hide div using select item.

I agree with @Lukasz Rzanek that we can use git plugin

But, I use option: checkout to a sub-direction what is enable as follow:
In Source Code Management, tick Git
click add button, choose checkout to a sub-directory

using Boost.Locale:

ws = boost::locale::conv::utf_to_utf<wchar_t>(s);

I would probably use something like:

string path = "C:/folder1/folder2/file.txt";
string lastFolderName = Path.GetFileName( Path.GetDirectoryName( path ) );

The inner call to GetDirectoryName will return the full path, while the outer call to GetFileName() will return the last path component - which will be the folder name.

This approach works whether or not the path actually exists. This approach, does however, rely on the path initially ending in a filename. If it's unknown whether the path ends in a filename or folder name - then it requires that you check the actual path to see if a file/folder exists at the location first. In that case, Dan Dimitru's answer may be more appropriate.

You need to provide an absolute path, not a relative path.

Provide the full path to the /data directory you are trying to write to.

You might want to add:

-webkit-appearance: none; 

if you need it looking consistent on Mobile Safari...

There are no events in JQuery to detect css changes.
Refer here: onHide() type event in jQuery
It is possible:

DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.
Source: Event detect when css property changed using Jquery

Without events, you can use setInterval function, like this:

var maxTime = 5000, // 5 seconds
    startTime = Date.now();

var interval = setInterval(function () {
        if ($('#element').is(':visible')) {
            // visible, do something
            clearInterval(interval);
        } else {
            // still hidden
            if (Date.now() - startTime > maxTime) {
                // hidden even after 'maxTime'. stop checking.
                clearInterval(interval);
            }
        }
    },
    100 // 0.1 second (wait time between checks)
);

Note that using setInterval this way, for keeping a watch, may affect your page's performance.

7th July 2018:
Since this answer is getting some visibility and up-votes recently, here is additional update on detecting css changes:

Mutation Events have been now replaced by the more performance friendly Mutation Observer.

The MutationObserver interface provides the ability to watch for changes being made to the DOM tree. It is designed as a replacement for the older Mutation Events feature which was part of the DOM3 Events specification.

Refer: https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

Create a generator using

g = myfunct()

Everytime you would like an item, use

next(g)

(or g.next() in Python 2.5 or below).

If the generator exits, it will raise StopIteration. You can either catch this exception if necessary, or use the default argument to next():

next(g, default_value)

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

public static int [] locations={1,2,3};

public static test dot=new test();

Declare the above variables above the main method and the code compiles fine.

public static void main(String[] args){

Try using cut... its fast and easy

First you have repeated spaces, you can squeeze those down to a single space between columns if thats what you want with tr -s ' '

If each column already has just one delimiter between it, you can use cut -d ' ' -f-2 to print fields (columns) <= 2.

for example if your data is in a file input.txt you can do one of the following:

cat input.txt | tr -s ' ' | cut -d ' ' -f-2

Or if you better reason about this problem by removing the 3rd column you can write the following

cat input.txt | tr -s ' ' | cut -d ' ' --complement -f3

cut is pretty powerful, you can also extract ranges of bytes, or characters, in addition to columns

excerpt from the man page on the syntax of how to specify the list range

Each LIST is made up of one range, or many ranges separated by commas.
Selected input is written in the same order that it is read, and is
written exactly once. Each range is one of:

  N     N'th byte, character or field, counted from 1
  N-    from N'th byte, character or field, to end of line
  N-M   from N'th to M'th (included) byte, character or field
  -M    from first to M'th (included) byte, character or field

so you also could have said you want specific columns 1 and 2 with...

cat input.txt | tr -s ' ' | cut -d ' ' -f1,2

DefaultForeColor is enough for this statement. This property gets the default foreground color of the control.

lblExample.ForeColor = DefaultForeColor;

Also, make sure that your environment variable is composed only by UPPER CASE LETTERS.... I don't know why (the documentation doesn't say nothing explicit about it, at least the link provided by @Andrew White), but if the variable is a lower case word (e.g. env.dummy), the variable always came empty or null...

i was struggling with this like an hour, until I decided to try an UPPER CASE VARIABLE, and problem solved.

OK Variables Examples:

• DUMMY
• DUMMY_ONE
• JBOSS_SERVER_PATH

(NOTE: I was using maven v3.0.5)

I Hope that this can help someone....

The error also happens when trying to use the

with multiprocessing.Pool() as pool:
   # ...

with a Python version that is too old (like Python 2.X) and does not support using with together with multiprocessing pools.

(See this answer https://stackoverflow.com/a/25968716/1426569 to another question for more details)

You need to move the pointer to the first row, before asking for data:

result.beforeFirst();
result.next();
String foundType = result.getString(1);

var sb = new StringBuilder();
sb.Append(beforeText);
sb.Insert(2, insertText);
afterText = sb.ToString();

Are you putting this line inside the class declaration? In that case you should remove the JSONDeserializer::.

There are many reasons why one might run into this error and thus a good checklist of what to check first helps considerably.

Let's consider that we are troubleshooting the following line:

require "/path/to/file"

Checklist

1. Check the file path for typos

• either check manually (by visually checking the path)

• or move whatever is called by require* or include* to its own variable, echo it, copy it, and try accessing it from a terminal:

  $path = "/path/to/file";
  
  echo "Path : $path";
  
  require "$path";
  

  Then, in a terminal:

  cat <file path pasted>
  

2. Check that the file path is correct regarding relative vs absolute path considerations

• if it is starting by a forward slash "/" then it is not referring to the root of your website's folder (the document root), but to the root of your server.
  • for example, your website's directory might be /users/tony/htdocs
• if it is not starting by a forward slash then it is either relying on the include path (see below) or the path is relative. If it is relative, then PHP will calculate relatively to the path of the current working directory.
  • thus, not relative to the path of your web site's root, or to the file where you are typing
  • for that reason, always use absolute file paths

Best practices :

In order to make your script robust in case you move things around, while still generating an absolute path at runtime, you have 2 options :

1. use require __DIR__ . "/relative/path/from/current/file". The __DIR__ magic constant returns the directory of the current file.

2. define a SITE_ROOT constant yourself :

   • at the root of your web site's directory, create a file, e.g. config.php

   • in config.php, write

     define('SITE_ROOT', __DIR__);
     

   • in every file where you want to reference the site root folder, include config.php, and then use the SITE_ROOT constant wherever you like :

     require_once __DIR__."/../config.php";
     ...
     require_once SITE_ROOT."/other/file.php";
     

These 2 practices also make your application more portable because it does not rely on ini settings like the include path.

3. Check your include path

Another way to include files, neither relatively nor purely absolutely, is to rely on the include path. This is often the case for libraries or frameworks such as the Zend framework.

Such an inclusion will look like this :

include "Zend/Mail/Protocol/Imap.php"

In that case, you will want to make sure that the folder where "Zend" is, is part of the include path.

You can check the include path with :

echo get_include_path();

You can add a folder to it with :

set_include_path(get_include_path().":"."/path/to/new/folder");

4. Check that your server has access to that file

It might be that all together, the user running the server process (Apache or PHP) simply doesn't have permission to read from or write to that file.

To check under what user the server is running you can use posix_getpwuid :

$user = posix_getpwuid(posix_geteuid());

var_dump($user);

To find out the permissions on the file, type the following command in the terminal:

ls -l <path/to/file>

and look at permission symbolic notation

5. Check PHP settings

If none of the above worked, then the issue is probably that some PHP settings forbid it to access that file.

Three settings could be relevant :

1. open_basedir
   • If this is set PHP won't be able to access any file outside of the specified directory (not even through a symbolic link).
   • However, the default behavior is for it not to be set in which case there is no restriction
   • This can be checked by either calling phpinfo() or by using ini_get("open_basedir")
   • You can change the setting either by editing your php.ini file or your httpd.conf file
2. safe mode
   • if this is turned on restrictions might apply. However, this has been removed in PHP 5.4. If you are still on a version that supports safe mode upgrade to a PHP version that is still being supported.
3. allow_url_fopen and allow_url_include
   • this applies only to including or opening files through a network process such as http:// not when trying to include files on the local file system
   • this can be checked with ini_get("allow_url_include") and set with ini_set("allow_url_include", "1")

Corner cases

If none of the above enabled to diagnose the problem, here are some special situations that could happen :

1. The inclusion of library relying on the include path

It can happen that you include a library, for example, the Zend framework, using a relative or absolute path. For example :

require "/usr/share/php/libzend-framework-php/Zend/Mail/Protocol/Imap.php"

But then you still get the same kind of error.

This could happen because the file that you have (successfully) included, has itself an include statement for another file, and that second include statement assumes that you have added the path of that library to the include path.

For example, the Zend framework file mentioned before could have the following include :

include "Zend/Mail/Protocol/Exception.php" 

which is neither an inclusion by relative path, nor by absolute path. It is assuming that the Zend framework directory has been added to the include path.

In such a case, the only practical solution is to add the directory to your include path.

2. SELinux

If you are running Security-Enhanced Linux, then it might be the reason for the problem, by denying access to the file from the server.

To check whether SELinux is enabled on your system, run the sestatus command in a terminal. If the command does not exist, then SELinux is not on your system. If it does exist, then it should tell you whether it is enforced or not.

To check whether SELinux policies are the reason for the problem, you can try turning it off temporarily. However be CAREFUL, since this will disable protection entirely. Do not do this on your production server.

setenforce 0

If you no longer have the problem with SELinux turned off, then this is the root cause.

To solve it, you will have to configure SELinux accordingly.

The following context types will be necessary :

• httpd_sys_content_t for files that you want your server to be able to read
• httpd_sys_rw_content_t for files on which you want read and write access
• httpd_log_t for log files
• httpd_cache_t for the cache directory

For example, to assign the httpd_sys_content_t context type to your website root directory, run :

semanage fcontext -a -t httpd_sys_content_t "/path/to/root(/.*)?"
restorecon -Rv /path/to/root

If your file is in a home directory, you will also need to turn on the httpd_enable_homedirs boolean :

setsebool -P httpd_enable_homedirs 1

In any case, there could be a variety of reasons why SELinux would deny access to a file, depending on your policies. So you will need to enquire into that. Here is a tutorial specifically on configuring SELinux for a web server.

3. Symfony

If you are using Symfony, and experiencing this error when uploading to a server, then it can be that the app's cache hasn't been reset, either because app/cache has been uploaded, or that cache hasn't been cleared.

You can test and fix this by running the following console command:

cache:clear

4. Non ACSII characters inside Zip file

Apparently, this error can happen also upon calling zip->close() when some files inside the zip have non-ASCII characters in their filename, such as "é".

A potential solution is to wrap the file name in utf8_decode() before creating the target file.

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

Everyone is posting such complicated answers.

I found an easy answer, for scrolling to the bottom, nicely:

final ScrollView myScroller = (ScrollView) findViewById(R.id.myScrollerView);

// Scroll views can only have 1 child, so get the first child's bottom,
// which should be the full size of the whole content inside the ScrollView
myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );

And, if necessary, you can put the second line of code, above, into a runnable:

myScroller.post( new Runnable() {
    @Override
    public void run() {
        myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );
    }
}

It took me much research and playing around to find this simple solution. I hope it helps you, too! :)

Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.

You can't read individual integers in a single line separately using BufferedReader as you do using Scannerclass. Although, you can do something like this in regard to your query :

import java.io.*;
class Test
{
   public static void main(String args[])throws IOException
    {
       BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
       int t=Integer.parseInt(br.readLine());
       for(int i=0;i<t;i++)
       {
         String str=br.readLine();
         String num[]=br.readLine().split(" ");
         int num1=Integer.parseInt(num[0]);
         int num2=Integer.parseInt(num[1]);
         //rest of your code
       }
    }
}

I hope this will help you.

You can use sed for this. For example:

$ sed -n '/Feb 23 13:55/,/Feb 23 14:00/p' /var/log/mail.log
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: connect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: lost connection after CONNECT from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: disconnect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie pop3d: Connection, ip=[::ffff:127.0.0.1]
...

How it works

The -n switch tells sed to not output each line of the file it reads (default behaviour).

The last p after the regular expressions tells it to print lines that match the preceding expression.

The expression '/pattern1/,/pattern2/' will print everything that is between first pattern and second pattern. In this case it will print every line it finds between the string Feb 23 13:55 and the string Feb 23 14:00.

More info here.

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

TL;DR

Git doesn't really store history the way you think it does. It calculates history at run-time based on an ancestor chain. If your ancestry is missing blobs, trees, or commits then you may not be able to fully recover your history.

Restore Missing Objects from Backups

The first thing you can try is to restore the missing items from backup. For example, see if you have a backup of the commit stored as .git/objects/98/4c11abfc9c2839b386f29c574d9e03383fa589. If so you can restore it.

You may also want to look into git-verify-pack and git-unpack-objects in the event that the commit has already been packed up and you want to return it to a loose object for the purposes of repository surgery.

Surgical Resection

If you can't replace the missing items from a backup, you may be able to excise the missing history. For example, you might examine your history or reflog to find an ancestor of commit 984c11abfc9c2839b386f29c574d9e03383fa589. If you find one intact, then:

1. Copy your Git working directory to a temporary directory somewhere.
2. Do a hard reset to the uncorrupted commit.
3. Copy your current files back into the Git work tree, but make sure you don't copy the .git folder back!
4. Commit the current work tree, and do your best to treat it as a squashed commit of all the missing history.

If it works, you will of course lose the intervening history. At this point, if you have a working history log, then it's a good idea to prune your history and reflogs of all unreachable commits and objects.

Full Restores and Re-Initialization

If your repository is still broken, then hopefully you have an uncorrupted backup or clone you can restore from. If not, but your current working directory contains valid files, then you can always re-initialize Git. For example:

rm -rf .git
git init
git add .
git commit -m 'Re-initialize repository without old history.'

It's drastic, but it may be your only option if your repository history is truly unrecoverable. YMMV.

For me, it works (java - android)

void RevokeAcess()
{
    try{
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("https://accounts.google.com/o/oauth2/revoke?token="+ACCESS_TOKEN);
    org.apache.http.HttpResponse response = client.execute(post);
    }
    catch(IOException e)
    {
    }
    CookieManager.getInstance().removeAllCookie(); // this is clear the cookies which tends to same user in android web view
}

You have to call this function in AsyncTask in android

I know this is old question. But maybe this can help you

JSON string

var jsonStr = '{ "bool": true, "number": 123, "string": "foo bar" }';

Pretty Print JSON

JSON.stringify(JSON.parse(jsonStr), null, 2);

Minify JSON

JSON.stringify(JSON.parse(jsonStr));

Im going to provide an argument against using socket.io.

I think using socket.io solely because it has fallbacks isnt a good idea. Let IE8 RIP.

In the past there have been many cases where new versions of NodeJS has broken socket.io. You can check these lists for examples... https://github.com/socketio/socket.io/issues?q=install+error

If you go to develop an Android app or something that needs to work with your existing app, you would probably be okay working with WS right away, socket.io might give you some trouble there...

Plus the WS module for Node.JS is amazingly simple to use.

Inside testing2.php you should print the $_POST array which contains all the data from the post. Also, $_POST['name'] should be available. For more info check $_POST on php.net.

Taking advantage of str.split's behavior with no sep parameter:

>>> s = " \t foo \n bar "
>>> "".join(s.split())
'foobar'

If you just want to remove spaces instead of all whitespace:

>>> s.replace(" ", "")
'\tfoo\nbar'

Premature optimization

Even though efficiency isn't the primary goal—writing clear code is—here are some initial timings:

$ python -m timeit '"".join(" \t foo \n bar ".split())'
1000000 loops, best of 3: 1.38 usec per loop
$ python -m timeit -s 'import re' 're.sub(r"\s+", "", " \t foo \n bar ")'
100000 loops, best of 3: 15.6 usec per loop

Note the regex is cached, so it's not as slow as you'd imagine. Compiling it beforehand helps some, but would only matter in practice if you call this many times:

$ python -m timeit -s 'import re; e = re.compile(r"\s+")' 'e.sub("", " \t foo \n bar ")'
100000 loops, best of 3: 7.76 usec per loop

Even though re.sub is 11.3x slower, remember your bottlenecks are assuredly elsewhere. Most programs would not notice the difference between any of these 3 choices.

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

If your page really relies on the fact that people won't be able to see that menu, you should know that modern browsers (for example Firefox) let the user decide if he really wants to disable it or not. So you have no guarantee at all that the menu would be really disabled.

As delnan pointed out, the match keyword in Scala has nothing to do with regexes. To find out whether a string matches a regex, you can use the String.matches method. To find out whether a string starts with an a, b or c in lower or upper case, the regex would look like this:

word.matches("[a-cA-C].*")

You can read this regex as "one of the characters a, b, c, A, B or C followed by anything" (. means "any character" and * means "zero or more times", so ".*" is any string).

HashMap is unordered per the second line of the documentation:

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Perhaps you can do as aix suggests and use a LinkedHashMap, or another ordered collection. This link can help you find the most appropriate collection to use.

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

It sounds like you're using Subclipse; is that correct? If so, there's a great list of decorators and their descriptions at this answer by Tim Stone.

Here's the relevant snippet for your case:

- A file not under version control. These are typically new files that you have not committed to the repository yet.
- A file with no local changes.

I had a big dataset and .loc[] was taking too long so I found a vectorized way to do it. Recall that you can set a column to a logical operator, so this works:

file['Flag'] = (file['Claim_Amount'] > 0)

This gives a Boolean, which I wanted, but you can multiply it by, say, 1 to make an Integer.

You can use any of the following:

\b      #A word break and will work for both spaces and end of lines.
(^|\s)  #the | means or. () is a capturing group. 


/\b(stackoverflow)\b/

Also, if you don't want to include the space in your match, you can use lookbehind/aheads.

(?<=\s|^)         #to look behind the match
(stackoverflow)   #the string you want. () optional
(?=\s|$)          #to look ahead.

You can use these solutions :

CSS rules applies to all tags that have following two classes :

.left.ui-class-selector {
    /*style here*/
}

CSS rules applies to all tags that have <li> with following two classes :

li.left.ui-class-selector {
   /*style here*/
}

jQuery solution :

$("li.left.ui-class-selector").css("color", "red");

Javascript solution :

document.querySelector("li.left.ui-class-selector").style.color = "red";

Why not simply return your calculated value and let the caller modify the global variable. It's not a good idea to manipulate a global variable within a function, as below:

Var1 = 1
Var2 = 0

def function(): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1

Var1 = function()

or even make local copies of the global variables and work with them and return the results which the caller can then assign appropriately

def function():
v1, v2 = Var1, Var2
# calculate using the local variables v1 & v2
return v1 - 1

Var1 = function()

Select the text of all items under produce:

//produce/item/text()

Select all the manager nodes in all departments:

//department/*

You may also use pyplot.text (see here).

def plot_embeddings(M_reduced, word2Ind, words):
    """ 
        Plot in a scatterplot the embeddings of the words specified in the list "words".
        Include a label next to each point.
    """
    for word in words:
        x, y = M_reduced[word2Ind[word]]
        plt.scatter(x, y, marker='x', color='red')
        plt.text(x+.03, y+.03, word, fontsize=9)
    plt.show()

M_reduced_plot_test = np.array([[1, 1], [-1, -1], [1, -1], [-1, 1], [0, 0]])
word2Ind_plot_test = {'test1': 0, 'test2': 1, 'test3': 2, 'test4': 3, 'test5': 4}
words = ['test1', 'test2', 'test3', 'test4', 'test5']

A bracket - [ or ] - means that end of the range is inclusive -- it includes the element listed. A parenthesis - ( or ) - means that end is exclusive and doesn't contain the listed element. So for [first1, last1), the range starts with first1 (and includes it), but ends just before last1.

Assuming integers:

• (0, 5) = 1, 2, 3, 4
• (0, 5] = 1, 2, 3, 4, 5
• [0, 5) = 0, 1, 2, 3, 4
• [0, 5] = 0, 1, 2, 3, 4, 5

The api is fairly easy to use.

// Lookup the dns, if the ip exists.
 if (!ip.isEmpty()) {
     InetAddress inetAddress = InetAddress.getByName(ip);
     dns = inetAddress.getCanonicalHostName(); 
 }

Recursive algorithm's time complexity can be better estimated by drawing recursion tree, In this case the recurrence relation for drawing recursion tree would be T(n)=T(n-1)+T(n-2)+O(1) note that each step takes O(1) meaning constant time,since it does only one comparison to check value of n in if block.Recursion tree would look like

          n
   (n-1)      (n-2)
(n-2)(n-3) (n-3)(n-4) ...so on

Here lets say each level of above tree is denoted by i hence,

i
0                        n
1            (n-1)                 (n-2)
2        (n-2)    (n-3)      (n-3)     (n-4)
3   (n-3)(n-4) (n-4)(n-5) (n-4)(n-5) (n-5)(n-6)

lets say at particular value of i, the tree ends, that case would be when n-i=1, hence i=n-1, meaning that the height of the tree is n-1. Now lets see how much work is done for each of n layers in tree.Note that each step takes O(1) time as stated in recurrence relation.

2^0=1                        n
2^1=2            (n-1)                 (n-2)
2^2=4        (n-2)    (n-3)      (n-3)     (n-4)
2^3=8   (n-3)(n-4) (n-4)(n-5) (n-4)(n-5) (n-5)(n-6)    ..so on
2^i for ith level

since i=n-1 is height of the tree work done at each level will be

i work
1 2^1
2 2^2
3 2^3..so on

Hence total work done will sum of work done at each level, hence it will be 2^0+2^1+2^2+2^3...+2^(n-1) since i=n-1. By geometric series this sum is 2^n, Hence total time complexity here is O(2^n)

Stored procedures:

(+)

• Great flexibility
• Full control over SQL
• The highest performance available

(-)

• Requires knowledge of SQL
• Stored procedures are out of source control
• Substantial amount of "repeating yourself" while specifying the same table and field names. The high chance of breaking the application after renaming a DB entity and missing some references to it somewhere.
• Slow development

ORM:

(+)

• Rapid development
• Data access code now under source control
• You're isolated from changes in DB. If that happens you only need to update your model/mappings in one place.

(-)

• Performance may be worse
• No or little control over SQL the ORM produces (could be inefficient or worse buggy). Might need to intervene and replace it with custom stored procedures. That will render your code messy (some LINQ in code, some SQL in code and/or in the DB out of source control).
• As any abstraction can produce "high-level" developers having no idea how it works under the hood

The general tradeoff is between having a great flexibility and losing lots of time vs. being restricted in what you can do but having it done very quickly.

There is no general answer to this question. It's a matter of holy wars. Also depends on a project at hand and your needs. Pick up what works best for you.

In my case the error was due to missing /data/db folder which the mongodb uses to store your data. Please type this command $sudo mongod in your terminal. If the error message is something like :

missing data/db folder error

Simply create the folder and you are good to go.

Either do it with CSS like the other answers did or change the text style color directly via the onMouseOver and onMouseOut event:

onmouseover="this.bgColor='white'; this.style.color='black'"

onmouseout="this.bgColor='black'; this.style.color='white'"

Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.

First, your IntentFilter must contain an event.

static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

Second, when you send a broadcast, use this same action:

Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);

Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.

Fourth, is your service declared in the AndroidManifest.xml?

Another interesting solution found here is using ES6 Map:

export enum Type {
  low,
  mid,
  high
}

export const TypeLabel = new Map<number, string>([
  [Type.low, 'Low Season'],
  [Type.mid, 'Mid Season'],
  [Type.high, 'High Season']
]);

USE

console.log(TypeLabel.get(Type.low)); // Low Season

I was facing the same problem trying to get around a custom check constraint that I needed to updated to allow different values. Problem is that ALL_CONSTRAINTS does't have a way to tell which column the constraint(s) are applied to. The way I managed to do it is by querying ALL_CONS_COLUMNS instead, then dropping each of the constraints by their name and recreate it.

select constraint_name from all_cons_columns where table_name = [TABLE_NAME] and column_name = [COLUMN_NAME];

I got the same issue while using .NET Framework 4.5. However, when I update the .NET version to 4.7.2 connection issue was resolved. Maybe this is due to SecurityProtocol support issue.

iirc :

cat filename.txt | awk '{ print $2 $4 }'

or, as mentioned in the comments :

awk '{ print $2 $4 }' filename.txt

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

Found This while searching, and it was after I updated my Java that the problem seemed to occur.

In Eclipse from your project:

Right-click on your project
Click Properties
Java build path: Libraries; Remove the "JRE System Library[J2SE 1.4]"
Click Add Library -> JRE System Library
Select the new "Execution Environment" or Workspace default JRE

I might consider using a dict and re.sub for something like this:

import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
    return repldict[match.group(0)]

regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
    for line in fin:
        fout.write(regex.sub(replfunc,line))

This has a slight advantage to replace in that it is a bit more robust to overlapping matches.

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

The key is "argument-less git-pull". When you do a git pull from a branch, without specifying a source remote or branch, git looks at the branch.<name>.merge setting to know where to pull from. git push -u sets this information for the branch you're pushing.

To see the difference, let's use a new empty branch:

$ git checkout -b test

First, we push without -u:

$ git push origin test
$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.test.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "test"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.

Now if we add -u:

$ git push -u origin test
Branch test set up to track remote branch test from origin.
Everything up-to-date
$ git pull
Already up-to-date.

Note that tracking information has been set up so that git pull works as expected without specifying the remote or branch.

Update: Bonus tips:

• As Mark mentions in a comment, in addition to git pull this setting also affects default behavior of git push. If you get in the habit of using -u to capture the remote branch you intend to track, I recommend setting your push.default config value to upstream.
• git push -u <remote> HEAD will push the current branch to a branch of the same name on <remote> (and also set up tracking so you can do git push after that).

ssh -q -o "BatchMode=yes" -i /home/sicmapp/.ssh/id_rsa <ID>@<Servername>.<domain> "echo 2>&1" && echo $host SSH_OK || echo $host SSH_NOK

I just want to correct a point here. ELF file is produced by the Linker, not the compiler.

The Compiler mission ends after producing the object files (*.o) out of the source code files. Linker links all .o files together and produces the ELF.

The command palette tells you the colours and their order when col = somefactor. It can also be used to set the colours as well.

palette()
[1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

In order to see that in your graph you could use a legend.

You'll notice that I only specified the new colours with 3 numbers. This will work like using a factor. I could have used the factor originally used to colour the points as well. This would make everything logically flow together... but I just wanted to show you can use a variety of things.

You could also be specific about the colours. Try ?rainbow for starters and go from there. You can specify your own or have R do it for you. As long as you use the same method for each you're OK.

Resource for android will be a option available when you go to your sdk manager and select Android 5.0. Download and install that. This will fix the problem of resource not found.

Putting my two cents here. I wanted to do the same without hardcoding the URL for my specific request. So i came up with this solution.

To append 'api' to my baseURL, I have my default baseURL set as,

axios.defaults.baseURL = '/api/';

Then in my specific request, after explicitly setting the method and url, i set the baseURL to '/'

axios({
    method:'post',
    url:'logout',
    baseURL: '/',
   })
   .then(response => {
      window.location.reload();
   })
   .catch(error => {
       console.log(error);
   });

Run eclipse.exe file as an Administrator. It worked for me

Since 0.17, you have to use the explicit conversions:

pd.to_datetime, pd.to_timedelta and pd.to_numeric

(As mentioned below, no more "magic", convert_objects has been deprecated in 0.17)

df = pd.DataFrame({'x': {0: 'a', 1: 'b'}, 'y': {0: '1', 1: '2'}, 'z': {0: '2018-05-01', 1: '2018-05-02'}})

df.dtypes

x    object
y    object
z    object
dtype: object

df

   x  y           z
0  a  1  2018-05-01
1  b  2  2018-05-02

You can apply these to each column you want to convert:

df["y"] = pd.to_numeric(df["y"])
df["z"] = pd.to_datetime(df["z"])    
df

   x  y          z
0  a  1 2018-05-01
1  b  2 2018-05-02

df.dtypes

x            object
y             int64
z    datetime64[ns]
dtype: object

and confirm the dtype is updated.

OLD/DEPRECATED ANSWER for pandas 0.12 - 0.16: You can use convert_objects to infer better dtypes:

In [21]: df
Out[21]: 
   x  y
0  a  1
1  b  2

In [22]: df.dtypes
Out[22]: 
x    object
y    object
dtype: object

In [23]: df.convert_objects(convert_numeric=True)
Out[23]: 
   x  y
0  a  1
1  b  2

In [24]: df.convert_objects(convert_numeric=True).dtypes
Out[24]: 
x    object
y     int64
dtype: object

Magic! (Sad to see it deprecated.)

To work around this problem, use SQL statements to make the changes to the metadata structure of a table.

This problem occurs when "Prevent saving changes that require table re-creation" option is enabled.

Source: Error message when you try to save a table in SQL Server 2008: "Saving changes is not permitted"

Also worth noting is that with update_attribute, the desired attribute to be updated doesn't need to be white listed with attr_accessible to update it as opposed to the mass assignment method update_attributes which will only update attr_accessible specified attributes.

You can try it. hope it will be useful.

SELECT * FROM `table` WHERE `Value` COLLATE latin1_general_cs = "IAreSavage"

You can use the information schema system views to find out pretty much anything about the tables you're interested in:

SELECT *
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE TABLE_NAME = 'yourTableName'
 ORDER BY ORDINAL_POSITION

You can also interrogate views, stored procedures and pretty much anything about the database using the Information_schema views.

You may use for this YUI library or use this article to implement

You need to loop over each of the elements in the slice and test. Equality for slices is not defined. However, there is a bytes.Equal function if you are comparing values of type []byte.

func testEq(a, b []Type) bool {

    // If one is nil, the other must also be nil.
    if (a == nil) != (b == nil) { 
        return false; 
    }

    if len(a) != len(b) {
        return false
    }

    for i := range a {
        if a[i] != b[i] {
            return false
        }
    }

    return true
}

SelectedText = this.combobox.SelectionBoxItem.ToString();

If you don't care about the columns where the missing files are, considering that the dataframe has the name New and one wants to assign the new dataframe to the same variable, simply run

New = New.drop_duplicates()

If you specifically want to remove the rows for the empty values in the column Tenant this will do the work

New = New[New.Tenant != '']

This may also be used for removing rows with a specific value - just change the string to the value that one wants.

Note: If instead of an empty string one has NaN, then

New = New.dropna(subset=['Tenant'])

You want

round(new MathContext(0));  // or perhaps another math context with rounding mode HALF_UP

Now it's more easy with management studio 2016.

Using SQL Server Management Studio

To copy data from one table to another

1.Open the table with columns you want to copy and the one you want to copy into by right-clicking the tables, and then clicking Design.

2.Click the tab for the table with the columns you want to copy and select those columns.

3.From the Edit menu, click Copy.

4.Open a new Query Editor window.

5.Right-click the Query Editor, and then click Design Query in Editor.

6.In the Add Table dialog box, select the source and destination table, click Add, and then close the Add Table dialog box.

7.Right-click an open area of the the Query Editor, point to Change Type, and then click Insert Results.

8.In the Choose Target Table for Insert Results dialog box, select the destination table.

9.In the upper portion of the Query Designer, click the source column in the source table.

10.The Query Designer has now created an INSERT query. Click OK to place the query into the original Query Editor window.

11.Execute the query to insert the data from the source table to the destination table.

C# Code:

Output:

Note:

We need to tell the compiler to not prefer a particular build platform.

Go to Visual Studio > Project Properties > Build > Uncheck "Prefer 32 bit"

Reason:

By default for most .NET Projects is "Any CPU 32-bit preferred"

When you uncheck 32 bit assembly will:

JIT to 32-bit code on 64 bit process

You can use str.translate, you just have to give it the right arguments:

>>> dels=''.join(chr(x) for x in range(256) if not chr(x).isdigit())
>>> '+1-617-555-1212'.translate(None, dels)
'16175551212'

N.b.: This won't work with unicode strings in Python2, or at all in Python3. For those environments, you can create a custom class to pass to unicode.translate:

>>> class C:
...    def __getitem__(self, i):
...       if unichr(i).isdigit():
...          return i
... 
>>> u'+1-617.555/1212'.translate(C())
u'16175551212'

This works with non-ASCII digits, too:

>>> print u'+\u00b9-\uff1617.555/1212'.translate(C()).encode('utf-8')
¹6175551212

@Bean was created to avoid coupling Spring and your business rules in compile time. It means you can reuse your business rules in other frameworks like PlayFramework or JEE.

You can still using the devil logic of setting options depending on your current Tmux version: see my previous answer.

But since Tmux v1.7, set-option adds "-q" to silence errors and not print out anything (see changelog). I recommend to use this feature, it's more readable and easily expandable.

Add this to your ~/.tmux.conf:

# from v2.1
set -gq mouse on
# before v2.1
set -gq mode-mouse on
set -gq mouse-resize-pane on
set -gq mouse-select-pane on
set -gq mouse-select-window on

Restar tmux or source-file your new .tmux.conf

Old question, but I did come across a similar situation. Don't think the above answer fully achieves what is needed. The missing piece is keychain; install it if it isn't already.

sudo apt-get install keychain

Then add the following line to your ~/.bashrc

eval $(keychain --eval id_rsa)

This will start the ssh-agent if it isn't running, connect to it if it is, load the ssh-agent environment variables into your shell, and load your ssh key.

Change id_rsa to whichever private key in ~/.ssh you want to load.

Some useful options for keychain:

• -q Quiet mode
• --noask Don't ask for the password upon start, but on demand when ssh key is actually used.

Some of the other answers return an actual string whereas I had more need to know the actual index int. And the answers that do that seem to over-complicate things. Using some of the other answers as inspiration, I did the following...

First, I created a function:

CREATE FUNCTION [dbo].[LastIndexOf] (@stringToFind varchar(max), @stringToSearch varchar(max))
RETURNS INT
AS
BEGIN
    RETURN (LEN(@stringToSearch) - CHARINDEX(@stringToFind,REVERSE(@stringToSearch))) + 1
END
GO

Then, in your query you can simply do this:

declare @stringToSearch varchar(max) = 'SomeText: SomeMoreText: SomeLastText'

select dbo.LastIndexOf(':', @stringToSearch)

The above should return 23 (the last index of ':')

Hope this made it a little easier for someone!

Use a Razor to dynamically change your URL by calling your action like this:

$.ajax({

    data: { data: "yourdata" },

It sounds like you're using an incorrect address:

Assuming you mean this is the address you give your client code then I suspect it should actually be:

Considering the thoughts from http://www.thoughtcrime.org/blog/the-cryptographic-doom-principle/ (in short: FIRST encrypt, THEN authenticate. Afterwards FIRST verify, THEN decrypt) I have implemented the following solution in node.js:

function encrypt(text,password){
  var cipher = crypto.createCipher(algorithm,password)
  var crypted = cipher.update(text,'utf8','hex')
  crypted += cipher.final('hex');
  return crypted;
}

function decrypt(text,password){
  var decipher = crypto.createDecipher(algorithm,password)
  var dec = decipher.update(text,'hex','utf8')
  dec += decipher.final('utf8');
  return dec;
}

function hashText(text){
    var hash = crypto.createHash('md5').update(text).digest("hex");
    //console.log(hash); 
    return hash;
}

function encryptThenAuthenticate(plainText,pw)
{
    var encryptedText = encrypt(plainText,pw);
    var hash = hashText(encryptedText);
    return encryptedText+"$"+hash;
}
function VerifyThenDecrypt(encryptedAndAuthenticatedText,pw)
{
    var encryptedAndHashArray = encryptedAndAuthenticatedText.split("$");
    var encrypted = encryptedAndHashArray[0];
    var hash = encryptedAndHashArray[1];
    var hash2Compare = hashText(encrypted);
    if (hash === hash2Compare)
    {
        return decrypt(encrypted,pw); 
    }
}

It can be tested with:

var doom = encryptThenAuthenticate("The encrypted text",user.cryptoPassword);
console.log(VerifyThenDecrypt(doom,user.cryptoPassword));

Hope this helps :-)

Bottom line: ! methods just change the value of the object they are called upon, whereas a method without ! returns a manipulated value without writing over the object the method was called upon.

Only use ! if you do not plan on needing the original value stored at the variable you called the method on.

I prefer to do something like:

foo = "word"
bar = foo.capitalize
puts bar

OR

foo = "word"
puts foo.capitalize

Instead of

foo = "word"
foo.capitalize!
puts foo

Just in case I would like to access the original value again.

This is round robin DNS. This is a quite simple solution for load balancing. Usually DNS servers rotate/shuffle the DNS records for each incoming DNS request. Unfortunately it's not a real solution for fail-over. If one of the servers fail, some visitors will still be directed to this failed server.

Generally, there is a mistake in the HTTP verb used eg:

The post needs an update after the links option is deprecated.

Basically, links is no longer needed because its main purpose, making container reachable by another by adding environment variable, is included implicitly with network. When containers are placed in the same network, they are reachable by each other using their container name and other alias as host.

For docker run, --link is also deprecated and should be replaced by a custom network.

docker network create mynet
docker run -d --net mynet --name container1 my_image
docker run -it --net mynet --name container1 another_image

depends_on expresses start order (and implicitly image pulling order), which was a good side effect of links.

For example like this:

var value = $("#a").find("#b").val()

For me, this was an issue with cyclic dependencies.

IOW, module A required module B, and module B required module A.

So in module B, require('./A') is an empty object rather than a function.

How to deal with cyclic dependencies in Node.js

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

The recommended approach in this case is to sort the data in the database, adding an ORDER BY at the end of the query that fetches the results, something like this:

SELECT temperature FROM temperatures ORDER BY temperature ASC;  -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order

If for some reason that is not an option, you can change the sorting order like this in Python:

templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int)               # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]

As has been pointed in the comments, the int key (or float if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.

In the parent process, fork()'s return value is the process ID of the child process. Stuff that value away somewhere for when you need to terminate the child process. fork() returns zero(0) in the child process.

When you need to terminate the child process, use the kill(2) function with the process ID returned by fork(), and the signal you wish to deliver (e.g. SIGTERM).

Remember to call wait() on the child process to prevent any lingering zombies.

Use document.activeElement, it is supported in all major browsers.

Previously, if you were trying to find out what form field has focus, you could not. To emulate detection within older browsers, add a "focus" event handler to all fields and record the last-focused field in a variable. Add a "blur" handler to clear the variable upon a blur event for the last-focused field.

If you need to remove the activeElement you can use blur; document.activeElement.blur(). It will change the activeElement to body.

Just want to share my own experience, I find that my Dynamic Web Module is locked, it is solved with the following steps:

First

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

You can create an alias in .bashrc file as follows

alias vg='valgrind --leak-check=full -v --track-origins=yes --log-file=vg_logfile.out'

So whenever you want to check memory leaks, just do simply

vg ./<name of your executable> <command line parameters to your executable>

This will generate a Valgrind log file in the current directory.

Although it creates a little clutter, it is worth putting final. Ides e.g eclipse can automatically put the final if you configure it to do so.

Regarding number of days in month just use static switch command and check if (year % 4 == 0) in which case February will have 29 days.

Minute, hour, day etc:

var someMillisecondValue = 511111222127;
var date = new Date(someMillisecondValue);
var minute = date.getMinutes();
var hour = date.getHours();
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
alert([minute, hour, day, month, year].join("\n"));

I tried with cygwin & gnuwin, and didn't worked for me, I guess because the makefile used mainly specific linux code.

What it worked was use Ubuntu Bash for Windows 10. This is a Marvel if you come from MAC as it is my case:

1. To install the Ubuntu Bash: https://itsfoss.com/install-bash-on-windows/
2. Once in the console, to install make simply type "make" and it gives the instructions to download it.

Extras:

1. Useful enable copy / paste on bash: Copy Paste in Bash on Ubuntu on Windows
2. In my case the make called Maven, so I have to install it as well: https://askubuntu.com/questions/722993/unable-to-locate-package-maven
3. To access windows filesystem C: drive, for example: "cd /mnt/c/"

Hope it helps

One notable reason to avoid overusing the heap is for performance -- specifically involving the performance of the default memory management mechanism used by C++. While allocation can be quite quick in the trivial case, doing a lot of new and delete on objects of non-uniform size without strict order leads not only to memory fragmentation, but it also complicates the allocation algorithm and can absolutely destroy performance in certain cases.

That's the problem that memory pools where created to solve, allowing to to mitigate the inherent disadvantages of traditional heap implementations, while still allowing you to use the heap as necessary.

Better still, though, to avoid the problem altogether. If you can put it on the stack, then do so.

In such a small cases where difference is less than 0 milliseconds you can get difference in nano seconds as well.

System.nanoTime()

Put all the ids into a variable called $ids and separate them with a ",":

$ids = "1,2,3,4,5,6";

Pass them like so:

$url = "?ids={$ids}";

Process them:

$ids = explode(",", $_GET['ids']);

Sure. Here's a completely silly program that demonstrates calling main recursively.

public class main
{
    public static void main(String[] args)
    {
        for (int i = 0; i < args.length; ++i)
        {
            if (args[i] != "")
            {
                args[i] = "";
                System.out.println((args.length - i) + " left");
                main(args);
            }
        }

    }
}

@AlexanderMP's answer is correct, but you can also consider handling nulls with coalesce:

declare @CodeNameString  nvarchar(max)
set @CodeNameString = null
SELECT @CodeNameString = Coalesce(@CodeNameString + ', ', '') + cast(CodeName as varchar) from AccountCodes  
select @CodeNameString

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

SQL keywords are case insensitive themselves.

Names of tables, columns etc, have a case sensitivity which is database dependent - you should probably assume that they are case sensitive unless you know otherwise (In many databases they aren't though; in MySQL table names are SOMETIMES case sensitive but most other names are not).

Comparing data using =, >, < etc, has a case awareness which is dependent on the collation settings which are in use on the individual database, table or even column in question. It's normal however, to keep collation fairly consistent within a database. We have a few columns which need to store case-sensitive values; they have a collation specifically set.

feel free to use this tool https://github.com/rooty0/ffmpeg_video_cutter I wrote awhile ago Pretty much that's cli front-end for ffmpeg... you just need to create a yaml what you want to cut out... something like this

cut_method: delete  # we're going to delete following video fragments from a video
timeframe:
  - from: start   # waiting for people to join the conference
    to: 4m
  - from: 10m11s  # awkward silence
    to: 15m50s
  - from: 30m5s   # Off-Topic Discussion
    to: end

and then just run a tool to get result

any one have best practice please comment below

You can bind listeners to one common functions -

$(window).bind("load resize scroll",function(e){
  // do stuff
});

Or another way -

$(window).bind({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

Alternatively, instead of using .bind() you can use .on() as bind directly maps to on(). And maybe .bind() won't be there in future jquery versions.

$(window).on({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

I believe my input is controlled since it has a value.

For an input to be controlled, its value must correspond to that of a state variable.

That condition is not initially met in your example because this.state.name is not initially set. Therefore, the input is initially uncontrolled. Once the onChange handler is triggered for the first time, this.state.name gets set. At that point, the above condition is satisfied and the input is considered to be controlled. This transition from uncontrolled to controlled produces the error seen above.

By initializing this.state.name in the constructor:

e.g.

this.state = { name: '' };

the input will be controlled from the start, fixing the issue. See React Controlled Components for more examples.

Unrelated to this error, you should only have one default export. Your code above has two.

you are using a smart quote “ instead of " here:

git.exe clone -v “ssh://
                ^^^ 

Make sure you use the plain-old-double-quote.

In case you have smaller data set, a way to achieve it by GUI is:

1. Open a query window
2. SELECT * FROM [table_name]
3. Select Import from the menu bar
4. Press Apply on the bottom right below the Result Grid

It is possible to insert an image in a Google Spreadsheet using Google Apps Script. However, the image should have been hosted publicly over internet. At present, it is not possible to insert private images from Google Drive.

You can use following code to insert an image through script.

  function insertImageOnSpreadsheet() {
  var SPREADSHEET_URL = 'INSERT_SPREADSHEET_URL_HERE';
  // Name of the specific sheet in the spreadsheet.
  var SHEET_NAME = 'INSERT_SHEET_NAME_HERE';

  var ss = SpreadsheetApp.openByUrl(SPREADSHEET_URL);
  var sheet = ss.getSheetByName(SHEET_NAME);

  var response = UrlFetchApp.fetch(
      'https://developers.google.com/adwords/scripts/images/reports.png');
  var binaryData = response.getContent();

  // Insert the image in cell A1.
  var blob = Utilities.newBlob(binaryData, 'image/png', 'MyImageName');
  sheet.insertImage(blob, 1, 1);
}

Above example has been copied from this link. Check noogui's reply for details.

In case you need to insert image from Google Drive, please check this link for current updates.

what language is this? If you're using a language that passes everything by reference like Java (except for native types), typically you can call .clone() method. The .clone() method is typically implemented by copying/cloning all relevant instance fields into the new object.

Try this example and you will understand also what is the difference between Associative Array and Object in JavaScript.

Associative Array

var a = new Array(1,2,3); 
a['key'] = 'experiment';
Array.isArray(a);

returns true

Keep in mind that a.length will be undefined, because length is treated as a key, you should use Object.keys(a).length to get the length of an Associative Array.

Object

var a = {1:1, 2:2, 3:3,'key':'experiment'}; 
Array.isArray(a)

returns false

JSON returns an Object ... could return an Associative Array ... but it is not like that

A Java String is internally always encoded in UTF-16 - but you really should think about it like this: an encoding is a way to translate between Strings and bytes.

So if you have an encoding problem, by the time you have String, it's too late to fix. You need to fix the place where you create that String from a file, DB or network connection.

To add timezone information in Python 3.2+

import datetime

>>> d = datetime.datetime.now(tz=datetime.timezone.utc)
>>> print(d.tzinfo)
'UTC+00:00'

This is the best way to do it, very simple.

$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');

echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;

recently I saw that sometimes the flash player doesn't recognize &wmode=opaque, istead you should pass &WMode=opaque too (notice the uppercase).

This error goes when startactivity doesn't know which is his activity. So you must add activity before startActivity()

you must set

context.startActivity(yourIntent);

I won't refer too your example as it is quite simple for a general answer (for example it doesn't contain templated functions ,which force you to implement them on the header) , what I follow as a rule of thumb is the pimpl idiom

It has quite some benefits as you get faster compilation times and the syntactic sugar :

class->member instead of class.member

The only drawback is the extra pointer you pay.

Let's add one more similar solution to the stack. This one also parses enums, and it looks nice. Very safe.

/// <summary>
    /// <para>More convenient than using T.TryParse(string, out T). 
    /// Works with primitive types, structs, and enums.
    /// Tries to parse the string to an instance of the type specified.
    /// If the input cannot be parsed, null will be returned.
    /// </para>
    /// <para>
    /// If the value of the caller is null, null will be returned.
    /// So if you have "string s = null;" and then you try "s.ToNullable...",
    /// null will be returned. No null exception will be thrown. 
    /// </para>
    /// <author>Contributed by Taylor Love (Pangamma)</author>
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="p_self"></param>
    /// <returns></returns>
    public static T? ToNullable<T>(this string p_self) where T : struct
    {
        if (!string.IsNullOrEmpty(p_self))
        {
            var converter = System.ComponentModel.TypeDescriptor.GetConverter(typeof(T));
            if (converter.IsValid(p_self)) return (T)converter.ConvertFromString(p_self);
            if (typeof(T).IsEnum) { T t; if (Enum.TryParse<T>(p_self, out t)) return t;}
        }

        return null;
    }

I have too low reputation to add comment to @bernie response, with response to @user1506145. I have run in to same issue.

The answer to it is a interval parameter which fixes things up

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import numpy as np
import datetime as dt

np.random.seed(1)

N = 100
y = np.random.rand(N)

now = dt.datetime.now()
then = now + dt.timedelta(days=100)
days = mdates.drange(now,then,dt.timedelta(days=1))

plt.gca().xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))
plt.gca().xaxis.set_major_locator(mdates.DayLocator(interval=5))
plt.plot(days,y)
plt.gcf().autofmt_xdate()
plt.show()

It's as easy as:

delete object.keyname;

or

delete object["keyname"];

Anything if you use directly in the Codeigniter framework directly, like base_url(), uri_string(), or word_limiter(), All of these are coming from some sort of Helper function of framework.

While some of Helpers may be available globally to use just like log_message() which are extremely useful everywhere, rest of the Helpers are optional and use case varies application to application. base_url() is a function defined in url helper of the Framework.

You can learn more about helper in Codeigniter user guide's helper section.

You can use base_url() function once your current class have access to it, for which you needs to load it first.

$this->load->helper('url')

You can use this line anywhere in the application before using the base_url() function.

If you need to use it frequently, I will suggest adding this function in config/autoload.php in the autoload helpers section.

Also, make sure you have well defined base_url value in your config/config.php file.

This will be the first configuration you will see,

$config['base_url'] = 'http://yourdomain.com/'; 

You can check quickly by

echo base_url();

Reference: https://codeigniter.com/user_guide/helpers/url_helper.html

Here below is a self composed myitoa() which is by far smaller in code, and reserves a FIXED array of 7 (including terminating 0) in char *mystring, which is often desirable. It is obvious that one can build the code with character-shift instead, if one need a variable-length output-string.

void myitoa(int number, char *mystring) {
  boolean negative = number>0;

  mystring[0] = number<0? '-' : '+';
  number = number<0 ? -number : number;
  for (int n=5; n>0; n--) {
     mystring[n] = ' ';
     if(number > 0) mystring[n] = number%10 + 48;
     number /= 10;
  }  
  mystring[6]=0;
}

You may like py2exe. You'll also find information in there for doing it on Linux.

You could do something like this:

<body>

<textarea id="txtArea" onkeypress="onTestChange();"></textarea>

<script>
function onTestChange() {
    var key = window.event.keyCode;

    // If the user has pressed enter
    if (key === 13) {
        document.getElementById("txtArea").value = document.getElementById("txtArea").value + "\n*";
        return false;
    }
    else {
        return true;
    }
}
</script>

</body>

Although the new line character feed from pressing enter will still be there, but its a start to getting what you want.

There is an odd case I got in VS2017, about the space between ‘Any’ and 'CPU'. this is not about using command prompt.

If you have a build project file, which could call other solution files. You can try to add the space between Any and CPU, like this (the Platform property value):

<MSBuild Projects="@(SolutionToBuild2)" Properties ="Configuration=$(ProjectConfiguration);Platform=Any CPU;Rerun=$(MsBuildReRun);" />

Before I fix this build issue, it is like this (ProjectPlatform is a global variable, was set to 'AnyCPU'):

<MSBuild Projects="@(SolutionToBuild1)" Properties ="Configuration=$(ProjectConfiguration);Platform=$(ProjectPlatform);Rerun=$(MsBuildReRun);" />

Also, we have a lot projects being called using $ (ProjectPlatform), which is 'AnyCPU' and work fine. If we open proj file, we can see lines liket this and it make sense.

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">

So my conclusion is, 'AnyCPU' works for calling project files, but not for calling solution files, for calling solution files, using 'Any CPU' (add the space.)

For now, I am not sure if it is a bug of VS project file or MSBuild. I am using VS2017 with VS2017 build tools installed.

What you have is a parse error. Those are thrown before any code is executed. A PHP file needs to be parsed in its entirety before any code in it can be executed. If there's a parse error in the file where you're setting your error levels, they won't have taken effect by the time the error is thrown.

Either break your files up into smaller parts, like setting the error levels in one file and then includeing another file which contains the actual code (and errors), or set the error levels outside PHP using php.ini or .htaccess directives.

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

    public int MinimumValue { get; private set; }
    public int MaxmimumValue { get; private set; }

    public void num()
    {
        int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
        MaxmimumValue = array[0];
        MinimumValue = array[0];

        foreach (int num in array)

        {

            if (num > MaxmimumValue) MaxmimumValue = num;
            if (num < MinimumValue) MinimumValue = num;
        }
        Console.WriteLine(MinimumValue);
        Console.WriteLine(MaxmimumValue);
    }

It is easy, but takes 3 steps:

1. In SQL Developer, enter your query in the "Worksheet" and highlight it, and press F9 to run it. The first 50 rows will be fetched into the "Query Result" window.
2. Click on any cell in the "Query Result" window to set the focus to that window.
3. Hold the Ctrl key and tap the "A" key.

All rows will be fetched into the "Query Result" window!

If you are using HTML Form element instead Laravel Form Builder, you must place method_field between your form opening tag and closing end. By doing this you may explicitly define form method type.

<form>
{{ method_field('PUT') }}
</form>

Just in case somebody else gets in the same situation like me yesterday (2016-06-22) and also does not succeed with the already posted approaches - on Lubuntu 14.04 it worked for me using the following chain of commands:

git clone https://github.com/google/googletest
cd googletest
cmake -DBUILD_SHARED_LIBS=ON .
make
cd googlemock
sudo cp ./libgmock_main.so ./gtest/libgtest.so gtest/libgtest_main.so ./libgmock.so /usr/lib/
sudo ldconfig

Setting the cursor for 'body' will change the cursor for the background of the page but not for controls on it. For example, buttons will still have the regular cursor when hovering over them. The following is what I am using:

To set the 'wait' cursor, create a style element and insert in the head:

var css = "* { cursor: wait; !important}";
var style = document.createElement("style");
style.type = "text/css";
style.id = "mywaitcursorstyle";
style.appendChild(document.createTextNode(css));
document.head.appendChild(style);

Then to restore the cursor, delete the style element:

var style = document.getElementById("mywaitcursorstyle");
if (style) {
  style.parentNode.removeChild(style);
}

If you want to put the content of example into install folder after build:

code/
  src/
  example/
  CMakeLists.txt

try add the following to your CMakeLists.txt:

install(DIRECTORY example/ DESTINATION example)

declare @locationType varchar(50);
declare @locationID int;

SELECT column1, column2
FROM viewWhatever
WHERE
@locationID = 
  CASE @locationType
      WHEN 'location' THEN account_location
      WHEN 'area' THEN xxx_location_area 
      WHEN 'division' THEN xxx_location_division 
  END

1. Implement javax.servlet.Filter.
2. In doFilter() method, cast the incoming ServletRequest to HttpServletRequest.
3. Use HttpServletRequest#getRequestURI() to grab the path.
4. Use straightforward java.lang.String methods like substring(), split(), concat() and so on to extract the part of interest and compose the new path.
5. Use either ServletRequest#getRequestDispatcher() and then RequestDispatcher#forward() to forward the request/response to the new URL (server-side redirect, not reflected in browser address bar), or cast the incoming ServletResponse to HttpServletResponse and then HttpServletResponse#sendRedirect() to redirect the response to the new URL (client side redirect, reflected in browser address bar).
6. Register the filter in web.xml on an url-pattern of /* or /Check_License/*, depending on the context path, or if you're on Servlet 3.0 already, use the @WebFilter annotation for that instead.

Don't forget to add a check in the code if the URL needs to be changed and if not, then just call FilterChain#doFilter(), else it will call itself in an infinite loop.

Alternatively you can also just use an existing 3rd party API to do all the work for you, such as Tuckey's UrlRewriteFilter which can be configured the way as you would do with Apache's mod_rewrite.

    border: 1px solid #c4c4c4;

    -moz-box-shadow: 0px 0px 8px #d9d9d9;
    -webkit-box-shadow: 0px 0px 8px #d9d9d9;
}

input:focus,textarea:focus { 
    outline: none;
    border: 1px solid #7bc1f7;
    box-shadow: 0px 0px 8px #7bc1f7;
    -moz-box-shadow: 0px 0px 8px #7bc1f7;
    -webkit-box-shadow: 0px 0px 8px #7bc1f7;
}

(Firstly read the other answers which has explained the for in the <label></label> tags. Well, both the tops answers are correct, but for my challenge, it was when you have several radio boxes, you should select for them a common name like name="r1" but with different ids id="r1_1" ... id="r1_2"

So this way the answer is more clear and removes the conflicts between name and ids as well.

You need different ids for different options of the radio box.

<input type="radio" name="r1" id="r1_1" />_x000D_
_x000D_
       <label for="r1_1">button text one</label>_x000D_
       <br/>_x000D_
       <input type="radio" name="r1" id="r1_2" />_x000D_
_x000D_
       <label for="r1_2">button text two</label>_x000D_
       <br/>_x000D_
       <input type="radio" name="r1" id="r1_3" />_x000D_
_x000D_
       <label for="r1_3">button text three</label>

I think df.replace() does the job, since pandas 0.13:

df = pd.DataFrame([
    [-0.532681, 'foo', 0],
    [1.490752, 'bar', 1],
    [-1.387326, 'foo', 2],
    [0.814772, 'baz', ' '],     
    [-0.222552, '   ', 4],
    [-1.176781,  'qux', '  '],         
], columns='A B C'.split(), index=pd.date_range('2000-01-01','2000-01-06'))

# replace field that's entirely space (or empty) with NaN
print(df.replace(r'^\s*$', np.nan, regex=True))

Produces:

                   A    B   C
2000-01-01 -0.532681  foo   0
2000-01-02  1.490752  bar   1
2000-01-03 -1.387326  foo   2
2000-01-04  0.814772  baz NaN
2000-01-05 -0.222552  NaN   4
2000-01-06 -1.176781  qux NaN

As Temak pointed it out, use df.replace(r'^\s+$', np.nan, regex=True) in case your valid data contains white spaces.

Going back to absolute basics here. The answers on this page and a little googling have brought me to the following resolution to my issue. Steps to restart the apache service with Xampp installed:-

1. Click the start button and type CMD (if on Windows Vista or later and Apache is installed as a service make sure this is an elevated command prompt)
2. In the command window that appears type cd C:\xampp\apache\bin (the default installation path for Xampp)
3. Then type httpd -k restart

I hope that this is of use to others just starting out with running a local Apache server.

If you are looking for PERFORMANCE, give where condition inside the db link query. Otherwise it fetch all data from the foreign table and apply the where condition.

INSERT INTO tblA (id,time) 
SELECT id, time FROM  dblink('dbname=dbname port=5432 host=10.10.90.190 user=postgresuser password=pass123', 
'select id, time from tblB  where time>'''||1000||'''')
AS t1(id integer, time integer)  

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

Well, the code that renders the button enabled/disabled:

if(name.getText().equals("")) {
    loginbt.setEnabled(false);
}else {
    loginbt.setEnabled(true);
}

must be written in javax.swing.event.ChangeListener and attached to the field (see here). A change in field's value should trigger the listener to reevaluate the object state. What did you expect?

I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.

head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt

If you don't want to rest of the lines from the file, just skip the tail part.

One is a Multi-column Correlated Update

UPDATE PRODUCTION a
SET (name, count) = (
  SELECT name, count
  FROM STAGING b
  WHERE a.ID = b.ID);

DEMO

You can use merge

MERGE INTO PRODUCTION a
USING ( select id, name, count 
          from STAGING ) b
ON ( a.id = b.id )
WHEN MATCHED THEN 
UPDATE SET  a.name = b.name,
            a.count = b.count

DEMO

getActivity().getFragmentManager() This worked or me.

Also take a look at here.

Try this example as simple as you can read, just copy save newfile.js do node newfile to run the application.

function myNew(next){
    console.log("Im the one who initates callback");
    next("nope", "success");
}


myNew(function(err, res){
    console.log("I got back from callback",err, res);
});

In case you are running it on Fedora or CentOS, this is what worked for me (PostgreSQL 9.6):

In terminal:

$ sudo visudo -f /etc/sudoers

modify the following text from:

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin

to

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/pgsql-9.6/bin

exit, then:

$ printenv PATH

$ sudo su postgres

$ psql

To exit postgreSQL terminal, you need to digit:

$ \q

You can try this script. :)

    <html>
    <head>
    <title>Div BG color</title>
    <script type="text/javascript">
    function Off(idecko)
    {
    document.getElementById(idecko).style.background="rgba(0,0,0,0)"; <!--- Default --->
    }
    function cOn(idecko)
    {
    document.getElementById(idecko).style.background="rgb(0,60,255)"; <!--- New content color --->
    }
    function hOn(idecko)
    {
    document.getElementById(idecko).style.background="rgb(60,255,0)"; <!--- New h2 color --->
    }
    </script>
    </head>
    <body>

    <div id="catestory">

        <div class="content" id="myid1" onmouseover="cOn('myid1'); hOn('h21')" onmouseout="Off('myid1'); Off('h21')">
          <h2 id="h21">some title here</h2>
          <p>some content here</p>
        </div>

        <div class="content" id="myid2" onmouseover="cOn('myid2'); hOn('h22')" onmouseout="Off('myid2'); Off('h22')">
          <h2 id="h22">some title here</h2>
          <p>some content here</p>
        </div>

        <div class="content" id="myid3" onmouseover="cOn('myid3'); hOn('h23')" onmouseout="Off('myid3'); Off('h23')">
          <h2 id="h23">some title here</h2>
          <p>some content here</p>
        </div>

    </div>

    </body>
<html>

If your base class is called Base, and your function is called FooBar() you can call it directly using Base::FooBar()

void Base::FooBar()
{
   printf("in Base\n");
}

void ChildOfBase::FooBar()
{
  Base::FooBar();
}

Why not something simple like this?

$(document).on('keypress', 'input', function(e) {

  if(e.keyCode == 13 && e.target.type !== 'submit') {
    e.preventDefault();
    return $(e.target).blur().focus();
  }

});

This way, you don't trigger the submit unless you're focused on the input type of "submit" already, and it puts you right where you left off. This also makes it work for inputs which are dynamically added to the page.

Note: The blur() is in front of the focus() for anyone who might have any "on blur" event listeners. It is not necessary for the process to work.

Run the Apache server, note down the port number(eg:8081) Open your browser and type localhost:8081(or apache's port number)

Here is my working solution :

// --------------------------
// SOAP Message creation
// --------------------------
SOAPMessage sm = MessageFactory.newInstance().createMessage();
sm.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");
sm.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-8");

SOAPPart sp = sm.getSOAPPart();
SOAPEnvelope se = sp.getEnvelope();
se.setEncodingStyle("http://schemas.xmlsoap.org/soap/encoding/");
se.setAttribute("xmlns:SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/");
se.setAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");
se.setAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");

SOAPBody sb = sm.getSOAPBody();
// 
// Add all input fields here ...
// 

SOAPConnection connection = SOAPConnectionFactory.newInstance().createConnection();
// -----------------------------------
// URL creation with TimeOut connexion
// -----------------------------------
URL endpoint = new URL(null,
                      "http://myDomain/myWebService.php",
                    new URLStreamHandler() { // Anonymous (inline) class
                    @Override
                    protected URLConnection openConnection(URL url) throws IOException {
                    URL clone_url = new URL(url.toString());
                    HttpURLConnection clone_urlconnection = (HttpURLConnection) clone_url.openConnection();
                    // TimeOut settings
                    clone_urlconnection.setConnectTimeout(10000);
                    clone_urlconnection.setReadTimeout(10000);
                    return(clone_urlconnection);
                    }
                });


try {
    // -----------------
    // Send SOAP message
    // -----------------
    SOAPMessage retour = connection.call(sm, endpoint);
}
catch(Exception e) {
    if ((e instanceof com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl) && (e.getCause()!=null) && (e.getCause().getCause()!=null) && (e.getCause().getCause().getCause()!=null)) {
        System.err.println("[" + e + "] Error sending SOAP message. Initial error cause = " + e.getCause().getCause().getCause());
    }
    else {
        System.err.println("[" + e + "] Error sending SOAP message.");

    }
}

Here is a more compact version inspired by justinfay's answer:

from collections import namedtuple
from functools import partial

Node = namedtuple('Node', ('val left right'))
Node.__new__ = partial(Node.__new__, left=None, right=None)

YES!....always style textarea using CSS and avoid the attributes, unless you need to support some very old agent that does not support style sheets. Otherwise, you have full power to use CSS. Below is my default CSS formatting for textarea that looks beautiful in any website. Customize it as you like. Comments are included below so you can see why I chose those CSS properties and values:

textarea {
    display: inline-block;
    margin: 0;
    padding: .2em;
    width: auto;
    min-width: 30em;
    /* The max-width "100%" value fixes a weird issue where width is too wide by default and extends beyond 100% of the parent in some agents. */
    max-width: 100%;
    /* Height "auto" will allow the text area to expand vertically in size with a horizontal scrollbar if pre-existing content is added to the box before rendering. Remove this if you want a pre-set height. Use "em" to match the font size set in the website. */
    height: auto;
    /* Use "em" to define the height based on the text size set in your website and the text rows in the box, not a static pixel value. */
    min-height: 10em;
    /* Do not use "border" in textareas unless you want to remove the 3D box most browsers assign and flatten the box design. */
    /*border: 1px solid black;*/
    cursor: text;
    /* Some textareas have a light gray background by default anyway. */
    background-color: #eee;
    /* Overflow "auto" allows the box to start with no scrollbars but add them as content fills the box. */
    overflow: auto;
    /* Resize creates a tab in the lower right corner of textarea for most modern browsers and allows users to resize the box manually. Note: Resize isn't supported by most older agents and IE. */
    resize: both;
}

In my "reset" element style sheet I set these values as defaults for "textarea" by default, which give all your textareas a nice look and feel with scrolling when detected, a resizing tab (non-IE browsers), and fixes for dimensions, including a height that allows the box to size itself based on existing content you put in it for the user and a width that does not break out beyond its parent containers limitations.

In imports

import re

In run time processing:

RE_TEST = r'test'
if re.match(RE_TEST, 'TeSt', re.IGNORECASE):

It should be mentioned that not using re.compile is wasteful. Every time the above match method is called, the regular expression will be compiled. This is also faulty practice in other programming languages. The below is the better practice.

In app initialization:

self.RE_TEST = re.compile('test', re.IGNORECASE)

In run time processing:

if self.RE_TEST.match('TeSt'):

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

const char * a;

This states pointer to constant character. For eg.

char b='s';
const char *a = &b;

Here a points to a constant char('s',in this case).You can't use a to change that value.But this declaration doesn't mean that value it points to is really a constant,it just means the value is a constant insofar as a is concerned. You can change the value of b directly by changing the value of b,but you can't change the value indirectly via the a pointer.

*a='t'; //INVALID b='t' ; //VALID

char * const a=&b

This states a constant pointer to char. It constraints a to point only to b however it allows you to alter the value of b.

Hope it helps!!! :)

This is not a permanent Fix for the problem but more like a workaround or hack

I had this very same issue when deploying my Angular App to gh-pages. First i was greeted with 404 messages when Refreshing my pages on gh-pages.

Then as what @gunter pointed out i started using HashLocationStrategy which was provided with Angular 2 .

But that came with it's own set of problems the # in the url it was really bad made the url look wierd like this https://rahulrsingh09.github.io/AngularConcepts/#/faq.

I started researching out about this problem and came across a blog. I tried giving it a shot and it worked .

Here is what i did as mentioned in that blog.

You’ll need to start by adding a 404.html file to your gh-pages repo that contains an empty HTML document inside it – but your document must total more than 512 bytes (explained below). Next put the following markup in your 404.html page’s head element:

<script>
  sessionStorage.redirect = location.href;
</script>
<meta http-equiv="refresh" content="0;URL='/REPO_NAME_HERE'"></meta>

This code sets the attempted entrance URL to a variable on the standard sessionStorage object and immediately redirects to your project’s index.html page using a meta refresh tag. If you’re doing a Github Organization site, don’t put a repo name in the content attribute replacer text, just do this: content="0;URL='/'"

In order to capture and restore the URL the user initially navigated to, you’ll need to add the following script tag to the head of your index.html page before any other JavaScript acts on the page’s current state:

<script>
  (function(){
    var redirect = sessionStorage.redirect;
    delete sessionStorage.redirect;
    if (redirect && redirect != location.href) {
      history.replaceState(null, null, redirect);
    }
  })();
</script>

This bit of JavaScript retrieves the URL we cached in sessionStorage over on the 404.html page and replaces the current history entry with it.

Reference backalleycoder Thanks to @Daniel for this workaround.

Now the above URL changes to https://rahulrsingh09.github.io/AngularConcepts/faq

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

tl;dr

LocalTime.parse( "10:30" )  // Parsed as 24-hour time.

java.time

Avoid the troublesome old date-time classes such as Date and Calendar that are now supplanted by the java.time classes.

LocalTime

The java.time classes provide a way to represent the time-of-day without a date and without a time zone: LocalTime

LocalTime lt = LocalTime.of( 10 , 30 );  // 10:30 AM.
LocalTime lt = LocalTime.of( 22 , 30 );  // 22:30 is 10:30 PM.

ISO 8601

The java.time classes use standard ISO 8601 formats by default when generating and parsing strings. These formats use 24-hour time.

String output = lt.toString();

LocalTime.of( 10 , 30 ).toString() : 10:30

LocalTime.of( 22 , 30 ).toString() : 22:30

So parsing 10:30 will be interpreted as 10:30 AM.

LocalTime lt = LocalTime.parse( "10:30" );  // 10:30 AM.

DateTimeFormatter

If you need to generate or parse strings in 12-hour click format with AM/PM, use the DateTimeFormatter class. Tip: make a habit of specifying a Locale.

I have simplified it : I have edited jackjoe's answer. The height auto etc not required I think.

CSS:

#container {
position: relative;
margin:0 auto;
width: 1000px;
background: #C63;
padding: 10px;
}

#leftCol {
background: #e8f6fe;
width: auto;
}

#rightCol {
float:right;
width:30%;
background: #aafed6;
}

.box {
position:relative;
clear:both;
background:#F39;
 }
</style>

HTML:

<div id="container">
