Programs & Examples On #Amortization

You can call tail +[line number] [file] and pipe it to grep -n which shows the line number:

tail +[line number] [file] | grep -n /regex/

The only problem with this method is the line numbers reported by grep -n will be [line number] - 1 less than the actual line number in [file].

Livelock

A thread often acts in response to the action of another thread. If the other thread's action is also a response to the action of another thread, then livelock may result.

As with deadlock, livelocked threads are unable to make further progress. However, the threads are not blocked — they are simply too busy responding to each other to resume work. This is comparable to two people attempting to pass each other in a corridor: Alphonse moves to his left to let Gaston pass, while Gaston moves to his right to let Alphonse pass. Seeing that they are still blocking each other, Alphonse moves to his right, while Gaston moves to his left. They're still blocking each other, and so on...

The main difference between livelock and deadlock is that threads are not going to be blocked, instead they will try to respond to each other continuously.

In this image, both circles (threads or processes) will try to give space to the other by moving left and right. But they can't move any further.

Another alternative, in my mind a better one, is using Pendulum instead of pytz. Consider the following simple code:

>>> import pendulum

>>> dt = pendulum.now().to_iso8601_string()
>>> print (dt)
2018-03-27T13:59:49+03:00
>>>

To install Pendulum and see their documentation, go here. It have tons of options (like simple ISO8601, RFC3339 and many others format support), better performance and tend to yield simpler code.

I am sure this can help. Create fileA anywhere in the directory and export all the functions.

export const func1=()=>{
    // do stuff
}
export const func2=()=>{
    // do stuff 
}
export const func3=()=>{
    // do stuff 
}
export const func4=()=>{
    // do stuff 
}
export const func5=()=>{
    // do stuff 
}

Here, in your React component class, you can simply write one import statement.

import React from 'react';
import {func1,func2,func3} from 'path_to_fileA';

class HtmlComponents extends React.Component {
    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }
    rippleClickFunction(){
        //do stuff. 
        // foo==bar
        func1(data);
        func2(data)
    }
   render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

Instead of configuring Tomcat to redirect requests, use Apache as a frontend with the Apache Tomcat connector so that Apache is only serving static content, while asking tomcat for dynamic content.

Using the JKmount directive (or others) you could specify exactly which requests are sent to Tomcat.

Requests for static content, such as images, would be served directly by Apache, using a standard virtual host configuration, while other requests, defined in the JKMount directive will be sent to Tomcat workers.

I think this implementation would give you the most flexibility and control on the overall application.

@noskio is correct... it just means that simplejson isn't found on your system and you need to install it for Python older than 2.6. one way is to use the setuptools easy_install tool. with it, you can install it as easily as: easy_install simplejson

UPDATE (Feb 2014): this is probably old news to many of you, but pip is a more modern tool that works in a similar way (i.e., pip install simplejson), only it can also uninstall apps.

In Python3, csv.reader expects, that passed iterable returns strings, not bytes. Here is one more solution to this problem, that uses codecs module:

import csv
import codecs
ifile  = open('sample.csv', "rb")
read = csv.reader(codecs.iterdecode(ifile, 'utf-8'))
for row in read :
    print (row) 

One more simple variant -

$ while read line
  do
      set $line          # assigns words in line to positional parameters
      echo "$3 $5"
  done < file

If you're not sure your input is going to be a Numpy array, you can use asarray with dtype=int instead of astype:

>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])

If the input array already has the correct dtype, asarray avoids the array copy while astype does not (unless you specify copy=False):

>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a)  # no copy :)
True
>>> a is a.astype(int)  # copy :(
False
>>> a is a.astype(int, copy=False)  # no copy :)
True

Since your list is already in ascending order, we can simply reverse the list.

>>> timestamps.reverse()
>>> timestamps
['2010-04-20 10:25:38', 
'2010-04-20 10:12:13', 
'2010-04-20 10:12:13', 
'2010-04-20 10:11:50', 
'2010-04-20 10:10:58', 
'2010-04-20 10:10:37',

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

example:

import java.util.*;   
import java.lang.Object;   
import java.text.Collator;   
public class CurrentTime{   
  public class CurrentTime   
{   
    public static void main( String[] args )   
    {   
        Calendar calendar = new GregorianCalendar();   
        String am_pm;   
        int hour = calendar.get( Calendar.HOUR );   
        int minute = calendar.get( Calendar.MINUTE );   
        // int second = calendar.get(Calendar.SECOND);   
        if( calendar.get( Calendar.AM_PM ) == 0 ){   
            am_pm = "AM";   
            if(hour >=10)   
                System.out.println( "welcome" );   
        }               
        else{   
            am_pm = "PM";   
            if(hour<6)   
                System.out.println( "welcome" );   
        }   

        String time = "Current Time : " + hour + ":" + minute + " " + am_pm;   
        System.out.println( time );    
    }   
}

Do note that on newer Apache versions the RewriteLog and RewriteLogLevel have been removed, and in fact will now trigger an error when trying to start Apache (at least on my XAMPP installation with Apache 2.4.2):

AH00526: Syntax error on line xx of path/to/config/file.conf: Invalid command 'RewriteLog', perhaps misspelled or defined by a module not included in the server configuration`

Instead, you're now supposed to use the general LogLevel directive, with a level of trace1 up to trace8. 'debug' didn't display any rewrite messages in the log for me.

Example: LogLevel warn rewrite:trace3

For the official documentation, see here.

Of course this also means that now your rewrite logs will be written in the general error log file and you'll have to sort them out yourself.

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have an LF.

If you are a single developer working on a windows machine, and you don't care that git automatically replaces LFs to CRLFs, you can turn this warning off by typing the following in the git command line

git config core.autocrlf true

If you want to make an intelligent decision how git should handle this, read the documentation

Here is a snippet

Formatting and Whitespace

Formatting and whitespace issues are some of the more frustrating and subtle problems that many developers encounter when collaborating, especially cross-platform. It’s very easy for patches or other collaborated work to introduce subtle whitespace changes because editors silently introduce them, and if your files ever touch a Windows system, their line endings might be replaced. Git has a few configuration options to help with these issues.

core.autocrlf

If you’re programming on Windows and working with people who are not (or vice-versa), you’ll probably run into line-ending issues at some point. This is because Windows uses both a carriage-return character and a linefeed character for newlines in its files, whereas Mac and Linux systems use only the linefeed character. This is a subtle but incredibly annoying fact of cross-platform work; many editors on Windows silently replace existing LF-style line endings with CRLF, or insert both line-ending characters when the user hits the enter key.

Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. You can turn on this functionality with the core.autocrlf setting. If you’re on a Windows machine, set it to true – this converts LF endings into CRLF when you check out code:

$ git config --global core.autocrlf true

If you’re on a Linux or Mac system that uses LF line endings, then you don’t want Git to automatically convert them when you check out files; however, if a file with CRLF endings accidentally gets introduced, then you may want Git to fix it. You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input

This setup should leave you with CRLF endings in Windows checkouts, but LF endings on Mac and Linux systems and in the repository.

If you’re a Windows programmer doing a Windows-only project, then you can turn off this functionality, recording the carriage returns in the repository by setting the config value to false:

$ git config --global core.autocrlf false

From Google documentation:

You can hide the navigation bar on Android 4.0 and higher using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag. This snippet hides both the navigation bar and the status bar:

View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
              | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

See below code. I am using that and it is opening my HomeActivity.

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.

select CONVERT(bigint,'60') as seconds 

and it returns

60

All proposed solutions didn't work for me but the closest one was from @Rishii.

I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.

.directive('jsr310Compatible', ['dateFilter', 'dateParser', function(dateFilter, dateParser) {
  return {
    restrict: 'EAC',
    require: 'ngModel',
    priority: 1,
    link: function(scope, element, attrs, ngModel) {
      var dateFormat = 'yyyy-MM-dd';

      ngModel.$parsers.push(function(viewValue) {
        return dateFilter(viewValue, dateFormat);
      });

      ngModel.$validators.date = function (modelValue, viewValue) {
        var value = modelValue || viewValue;

        if (!attrs.ngRequired && !value) {
          return true;
        }

        if (angular.isNumber(value)) {
          value = new Date(value);
        }

        if (!value) {
          return true;
        }
        else if (angular.isDate(value) && !isNaN(value)) {
          return true;
        }
        else if (angular.isString(value)) {
          var date = dateParser.parse(value, dateFormat);
          return !isNaN(date);
        }
        else {
          return false;
        }
      };
    }
  };
}])

add plt.figure(figsize=(16,5)) before the sns.heatmap and play around with the figsize numbers till you get the desired size

...

plt.figure(figsize = (16,5))

ax = sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5)

@Nanocom's answer works for me. It may be that lines have to be at the end, or could be because has to be after of some the bean class like this:

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
<bean class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler" />    

<mvc:resources mapping="/resources/**" 
               location="/resources/" 
               cache-period="10000" />

Firstly add a div with id.

<div id="my_map_add" style="width:100%;height:300px;"></div>

<script type="text/javascript">
function my_map_add() {
var myMapCenter = new google.maps.LatLng(28.5383866, 77.34916609);
var myMapProp = {center:myMapCenter, zoom:12, scrollwheel:false, draggable:false, mapTypeId:google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("my_map_add"),myMapProp);
var marker = new google.maps.Marker({position:myMapCenter});
marker.setMap(map);
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=your_key&callback=my_map_add"></script>

$http({
    url: 'http://localhost:8080/example/teste',
    dataType: 'json',
    method: 'POST',
    data: '',
    headers: {
        "Content-Type": "application/json"
    }

}).success(function(response){
    $scope.response = response;
}).error(function(error){
    $scope.error = error;
});

Try like this.

Tested on SQLite:

SELECT c.*, p.*, max(p.date)
FROM customer c
LEFT OUTER JOIN purchase p
ON c.id = p.customer_id
GROUP BY c.id

The max() aggregate function will make sure that the latest purchase is selected from each group (but assumes that the date column is in a format whereby max() gives the latest - which is normally the case). If you want to handle purchases with the same date then you can use max(p.date, p.id).

In terms of indexes, I would use an index on purchase with (customer_id, date, [any other purchase columns you want to return in your select]).

The LEFT OUTER JOIN (as opposed to INNER JOIN) will make sure that customers that have never made a purchase are also included.

Use the Date property:

var dateAndTime = DateTime.Now;
var date = dateAndTime.Date;

The date variable will contain the date, the time part will be 00:00:00.

ok in the fitsy we need salt salt must be unique so let generate it

   /**
     * Generating string
     * @param $size
     * @return string
     */
    function Uniwur_string($size){
        $text = md5(uniqid(rand(), TRUE));
        RETURN substr($text, 0, $size);
    }

also we need the hash I`m using sha512 it is the best and it is in php

   /**
     * Hashing string
     * @param $string
     * @return string
     */
    function hash($string){
        return hash('sha512', $string);
    }

so now we can use this functions to generate safe password

// generating unique password
$password = Uniwur_string(20); // or you can add manual password
// generating 32 character salt
$salt = Uniwur_string(32);
// now we can manipulate this informations

// hashin salt for safe
$hash_salt = hash($salt);
// hashing password
$hash_psw = hash($password.$hash_salt);

now we need to save in database our $hash_psw variable value and $salt variable

and for authorize we will use same steps...

it is the best way to safe our clients passwords...

P.s. for last 2 steps you can use your own algorithm... but be sure that you can generate this hashed password in the future when you need to authorize user...

Try something like this to get the format you wanted:

Get-WebBinding | % {
    $name = $_.ItemXPath -replace '(?:.*?)name=''([^'']*)(?:.*)', '$1'
    New-Object psobject -Property @{
        Name = $name
        Binding = $_.bindinginformation.Split(":")[-1]
    }
} | Group-Object -Property Name | 
Format-Table Name, @{n="Bindings";e={$_.Group.Binding -join "`n"}} -Wrap

You can achieve this by setting the android:noHistory attribute to "true" in the relevant <activity> entries in your AndroidManifest.xml file. For example:

<activity
    android:name=".AnyActivity"
    android:noHistory="true" />

Please check which user account you use to execute our task. It may happen that you run your task with different user then your default user, and this user requires some extra privileges. Also it may happen that the task is executed but you cant see any effect because the batch file waits for some user response so please check task manager if you see your process running. Once it happen that I schedule a batch with svn update of some web page and the process hangs because svn asked for accepting server certificate.

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

Your program has no knowledge of where your VS project is, so see get path for my .exe and go ../.. to get your project's path.

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

foreach (DataRow row in Datatable.Rows) 
{
    if (row["CountryName"].ToString() == userInput) 
    {
        return row["CountryID"];
    }
}

While this may not compile directly you should get the idea, also I'm sure it would be vastly superior to do the query through SQL as a huge datatable will take a long time to run through all the rows.

To do what you want, using the fs.createWriteStream(path[, options]) function in a ES6 way:

const fs = require('fs');
const writeStream = fs.createWriteStream('file.txt');
const pathName = writeStream.path;
 
let array = ['1','2','3','4','5','6','7'];
  
// write each value of the array on the file breaking line
array.forEach(value => writeStream.write(`${value}\n`));

// the finish event is emitted when all data has been flushed from the stream
writeStream.on('finish', () => {
   console.log(`wrote all the array data to file ${pathName}`);
});

// handle the errors on the write process
writeStream.on('error', (err) => {
    console.error(`There is an error writing the file ${pathName} => ${err}`)
});

// close the stream
writeStream.end();

Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.

If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.

Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.

1) First Insert JS file path in an index.html file :

<script src="assets/video.js" type="text/javascript"></script>

2) Import JS file and declare the variable in component.ts :

• import './../../../assets/video.js';

• declare var RunPlayer: any;

  NOTE: Variable name should be same as the name of a function in js file

3) Call the js method in the component

ngAfterViewInit(){

    setTimeout(() => {
        new RunPlayer();
    });

}

The command line arguments are separated by space. If you want provide an argument with a space in it, you should quote it. So use git commit -m "initial commit".

You should first create a new environment in conda. From the terminal, type:

$ conda create --name my_env pandas ipython

Python will be installed automatically as part of this installation. After selecting [y] to confirm, you now need to activate this environment:

$ source activate my_env

On Windows I believe it is just:

$ activate my_env

Now, confirm installed packages:

$ conda list

Finally, start python and run your session.

$ ipython

By default Spring Security redirects user to the URL that he originally requested (/Load.do in your case) after login.

You can set always-use-default-target to true to disable this behavior:

 <security:http auto-config="true">

    <security:intercept-url pattern="/Admin**" access="hasRole('PROGRAMMER') or hasRole('ADMIN')"/>
    <security:form-login login-page="/Load.do"
        default-target-url="/Admin.do?m=loadAdminMain"
        authentication-failure-url="/Load.do?error=true"
        always-use-default-target = "true"
        username-parameter="j_username"
        password-parameter="j_password"
        login-processing-url="/j_spring_security_check"/>
    <security:csrf/><!-- enable Cross Site Request Forgery protection -->
</security:http>

This answer mentions Json.NET but stops short of telling you how you can use Json.NET to serialize a dictionary:

return JsonConvert.SerializeObject( myDictionary );

As opposed to JavaScriptSerializer, myDictionary does not have to be a dictionary of type <string, string> for JsonConvert to work.

To add to the response from @Anish, if you are having issues with not seeing the text when exporting the SVG to an image, you can create a recursive function to loop through the children of the SVGDocument, try to cast it to a SvgText if possible (add your own error checking) and set the font family and style.

    foreach(var child in svgDocument.Children)
    {
        SetFont(child);
    }

    public void SetFont(SvgElement element)
    {
        foreach(var child in element.Children)
        {
            SetFont(child); //Call this function again with the child, this will loop
                            //until the element has no more children
        }

        try
        {
            var svgText = (SvgText)parent; //try to cast the element as a SvgText
                                           //if it succeeds you can modify the font

            svgText.Font = new Font("Arial", 12.0f);
            svgText.FontSize = new SvgUnit(12.0f);
        }
        catch
        {

        }
    }

Let me know if there are questions.

Although a bit unstandard, a possible solution is to contain the content you want to show/hide inside the <a> so it can be reachable through CSS:

http://jsfiddle.net/Jdrdh/2/

a .hidden {_x000D_
  visibility: hidden;_x000D_
}_x000D_
_x000D_
a:visited .hidden {_x000D_
  visibility: visible;_x000D_
}

<div id="container">_x000D_
  <a href="#">_x000D_
        A_x000D_
        <div class="hidden">hidden content</div>_x000D_
    </a>_x000D_
</div>

It is as simple as:

String charIs = string.charAt(index) + "";

If the string containing the phone number will always start this way (+33 or another country code) you should use regex to parse and get the country code and then use the library to get the country associated to the number.

if you follow

UPDATE table SET name = NULL

then name is "" not NULL IN MYSQL means your query

SELECT * FROM table WHERE name = NULL not work or disappoint yourself

Create a new custom object and add it to the object array that Import-Csv creates.

$fileContent = Import-csv $file -header "Date", "Description"
$newRow = New-Object PsObject -Property @{ Date = 'Text4' ; Description = 'Text5' }
$fileContent += $newRow

Another way to do this would be to by using map.

>>> a
[1, 2, 3]
>>> b
[4, 5, 6]
>>> for i,j in map(None,a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

One difference in using map compared to zip is, with zip the length of new list is
same as the length of shortest list. For example:

>>> a
[1, 2, 3, 9]
>>> b
[4, 5, 6]
>>> for i,j in zip(a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

Using map on same data:

>>> for i,j in map(None,a,b):
    ...   print i,j
    ...

    1 4
    2 5
    3 6
    9 None

Assuming you want a field length of 2 with leading zeros you'd do this:

import Foundation

for myInt in 1 ... 3 {
    print(String(format: "%02d", myInt))
}

output:

01
02
03

This requires import Foundation so technically it is not a part of the Swift language but a capability provided by the Foundation framework. Note that both import UIKit and import Cocoa include Foundation so it isn't necessary to import it again if you've already imported Cocoa or UIKit.

The format string can specify the format of multiple items. For instance, if you are trying to format 3 hours, 15 minutes and 7 seconds into 03:15:07 you could do it like this:

let hours = 3
let minutes = 15
let seconds = 7
print(String(format: "%02d:%02d:%02d", hours, minutes, seconds))

output:

03:15:07

This is an IndexError in python, which means that we're trying to access an index which isn't there in the tensor. Below is a very simple example to understand this error.

# create an empty array of dimension `0`
In [14]: arr = np.array([], dtype=np.int64) 

# check its shape      
In [15]: arr.shape  
Out[15]: (0,)

with this array arr in place, if we now try to assign any value to some index, for example to the index 0 as in the case below

In [16]: arr[0] = 23     

Then, we will get an IndexError, as below:

---

IndexError                                Traceback (most recent call last)
<ipython-input-16-0891244a3c59> in <module>
----> 1 arr[0] = 23

IndexError: index 0 is out of bounds for axis 0 with size 0

The reason is that we are trying to access an index (here at 0^th position), which is not there (i.e. it doesn't exist because we have an array of size 0).

In [19]: arr.size * arr.itemsize  
Out[19]: 0

So, in essence, such an array is useless and cannot be used for storing anything. Thus, in your code, you've to follow the traceback and look for the place where you're creating an array/tensor of size 0 and fix that.

I was using Angular 8 and was .NET core API. I add the following in my service web.config file. That resolve my error.

<system.webServer>
  <modules runAllManagedModulesForAllRequests="false">
    <remove name="WebDAVModule" />
  </modules>
</system.webServer>

I find that the --tree-filter option used in other answers can be very slow, especially on larger repositories with lots of commits.

Here is the method I use to completely remove a directory from the git history using the --index-filter option, which runs much quicker:

# Make a fresh clone of YOUR_REPO
git clone YOUR_REPO
cd YOUR_REPO

# Create tracking branches of all branches
for remote in `git branch -r | grep -v /HEAD`; do git checkout --track $remote ; done

# Remove DIRECTORY_NAME from all commits, then remove the refs to the old commits
# (repeat these two commands for as many directories that you want to remove)
git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY_NAME/' --prune-empty --tag-name-filter cat -- --all
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

# Ensure all old refs are fully removed
rm -Rf .git/logs .git/refs/original

# Perform a garbage collection to remove commits with no refs
git gc --prune=all --aggressive

# Force push all branches to overwrite their history
# (use with caution!)
git push origin --all --force
git push origin --tags --force

You can check the size of the repository before and after the gc with:

git count-objects -vH

I accidentally turned on offline mode.

To disable it: in the Maven tool window, click The Toggle Offline Mode button.

Took a lot of googling but here is what I do in Python for MySql when I want to delete multiple items from a single table using a list of values.

#create some empty list
values = []
#continue to append the values you want to delete to it
#BUT you must ensure instead of a string it's a single value tuple
values.append(([Your Variable],))
#Then once your array is loaded perform an execute many
cursor.executemany("DELETE FROM YourTable WHERE ID = %s", values)

A margin-top of -8px means it will be 8px higher than if it had 0 margin.

A margin-bottom of 8px means that the thing below it will be 8px further down that if it had 0 margin.

Make sure your account uses IIS 7. For more information, see Customizing IIS Settings on Your Windows Hosting Account. Follow the instructions in Changing Pipeline Mode on Your Windows IIS 7 Hosting Account. Select Integrated Pipeline Mode. In your Project References section, set Copy Local to True for the following assemblies:

System.Web.Abstractions
System.Web.Helpers
System.Web.Routing
System.Web.Mvc
System.Web.WebPages

Add the following assemblies to your project, and then set Copy Local to True:

Microsoft.Web.Infrastructure
System.Web.Razor
System.Web.WebPages.Deployment
System.Web.WebPages.Razor
Publish your application.

What you need is this:

a, b, c = [0,3,5] # Unpack the list, now a, b, and c are ints
a = 1             # `a` did equal 0, not [0,3,5]
print(a)
print(b)
print(c)

Maybe you can use a work around and try something like:

import datetime
#import mysql
import MySQLdb
conn = MySQLdb.connect(host = '127.0.0.1',user = 'someUser', passwd = 'foobar',db = 'foobardb')
cursor = conn.cursor()

Copy the cell. Paste special as link. Will update with original. No formula though.

Andy Hayden mentioned the correct function (to_sql). In this answer, I'll give a complete example, which I tested with Python 3.5 but should also work for Python 2.7 (and Python 3.x):

First, let's create the dataframe:

# Create dataframe
import pandas as pd
import numpy as np

np.random.seed(0)
number_of_samples = 10
frame = pd.DataFrame({
    'feature1': np.random.random(number_of_samples),
    'feature2': np.random.random(number_of_samples),
    'class':    np.random.binomial(2, 0.1, size=number_of_samples),
    },columns=['feature1','feature2','class'])

print(frame)

Which gives:

   feature1  feature2  class
0  0.548814  0.791725      1
1  0.715189  0.528895      0
2  0.602763  0.568045      0
3  0.544883  0.925597      0
4  0.423655  0.071036      0
5  0.645894  0.087129      0
6  0.437587  0.020218      0
7  0.891773  0.832620      1
8  0.963663  0.778157      0
9  0.383442  0.870012      0

To import this dataframe into a MySQL table:

# Import dataframe into MySQL
import sqlalchemy
database_username = 'ENTER USERNAME'
database_password = 'ENTER USERNAME PASSWORD'
database_ip       = 'ENTER DATABASE IP'
database_name     = 'ENTER DATABASE NAME'
database_connection = sqlalchemy.create_engine('mysql+mysqlconnector://{0}:{1}@{2}/{3}'.
                                               format(database_username, database_password, 
                                                      database_ip, database_name))
frame.to_sql(con=database_connection, name='table_name_for_df', if_exists='replace')

One trick is that MySQLdb doesn't work with Python 3.x. So instead we use mysqlconnector, which may be installed as follows:

pip install mysql-connector==2.1.4  # version avoids Protobuf error

Output:

Note that to_sql creates the table as well as the columns if they do not already exist in the database.

Here is an attempt to get << and >> stream operators on enum automatically with an one line macro command only...

Definitions:

#include <string>
#include <iostream>
#include <stdexcept>
#include <algorithm>
#include <iterator>
#include <sstream>
#include <vector>

#define MAKE_STRING(str, ...) #str, MAKE_STRING1_(__VA_ARGS__)
#define MAKE_STRING1_(str, ...) #str, MAKE_STRING2_(__VA_ARGS__)
#define MAKE_STRING2_(str, ...) #str, MAKE_STRING3_(__VA_ARGS__)
#define MAKE_STRING3_(str, ...) #str, MAKE_STRING4_(__VA_ARGS__)
#define MAKE_STRING4_(str, ...) #str, MAKE_STRING5_(__VA_ARGS__)
#define MAKE_STRING5_(str, ...) #str, MAKE_STRING6_(__VA_ARGS__)
#define MAKE_STRING6_(str, ...) #str, MAKE_STRING7_(__VA_ARGS__)
#define MAKE_STRING7_(str, ...) #str, MAKE_STRING8_(__VA_ARGS__)
#define MAKE_STRING8_(str, ...) #str, MAKE_STRING9_(__VA_ARGS__)
#define MAKE_STRING9_(str, ...) #str, MAKE_STRING10_(__VA_ARGS__)
#define MAKE_STRING10_(str) #str

#define MAKE_ENUM(name, ...) MAKE_ENUM_(, name, __VA_ARGS__)
#define MAKE_CLASS_ENUM(name, ...) MAKE_ENUM_(friend, name, __VA_ARGS__)

#define MAKE_ENUM_(attribute, name, ...) name { __VA_ARGS__ }; \
    attribute std::istream& operator>>(std::istream& is, name& e) { \
        const char* name##Str[] = { MAKE_STRING(__VA_ARGS__) }; \
        std::string str; \
        std::istream& r = is >> str; \
        const size_t len = sizeof(name##Str)/sizeof(name##Str[0]); \
        const std::vector<std::string> enumStr(name##Str, name##Str + len); \
        const std::vector<std::string>::const_iterator it = std::find(enumStr.begin(), enumStr.end(), str); \
        if (it != enumStr.end())\
            e = name(it - enumStr.begin()); \
        else \
            throw std::runtime_error("Value \"" + str + "\" is not part of enum "#name); \
        return r; \
    }; \
    attribute std::ostream& operator<<(std::ostream& os, const name& e) { \
        const char* name##Str[] = { MAKE_STRING(__VA_ARGS__) }; \
        return (os << name##Str[e]); \
    }

Usage:

// Declare global enum
enum MAKE_ENUM(Test3, Item13, Item23, Item33, Itdsdgem43);

class Essai {
public:
    // Declare enum inside class
    enum MAKE_CLASS_ENUM(Test, Item1, Item2, Item3, Itdsdgem4);

};

int main() {
    std::cout << Essai::Item1 << std::endl;

    Essai::Test ddd = Essai::Item1;
    std::cout << ddd << std::endl;

    std::istringstream strm("Item2");
    strm >> ddd;

    std::cout << (int) ddd << std::endl;
    std::cout << ddd << std::endl;
}

Not sure about the limitations of this scheme though... comments are welcome!

What language are you using?

If you can use ruby, then maruku can be configured to process maths using various latex->MathML converters. Instiki uses this. It's also possible to extend PHPMarkdown to use itex2MML as well to convert maths. Basically, you insert extra steps in the Markdown engine at the appropriate points.

So with ruby and PHP, this is done. I guess these solutions could also be adapted to other languages - I've gotten the itex2MML extension to produce perl bindings as well.

Yes you can. Since you are using spring, check out @PropertySource anotation.

Anotate your configuration with

@PropertySource("application-${spring.profiles.active}.properties")

You can call it what ever you like, and add inn multiple property files if you like too. Can be nice if you have more sets and/or defaults that belongs to all environments (can be written with @PropertySource{...,...,...} as well).

@PropertySources({
  @PropertySource("application-${spring.profiles.active}.properties"),
  @PropertySource("my-special-${spring.profiles.active}.properties"),
  @PropertySource("overridden.properties")})

Then you can start the application with environment

-Dspring.active.profiles=test

In this example, name will be replaced with application-test-properties and so on.

Simplest solution:

$date = new DateTime('+1 day');
echo $date->format('Y-m-d H:i:s');

You can try: .order_by(ClientTotal.id.desc())

session = Session()
auth_client_name = 'client3' 
result_by_auth_client = session.query(ClientTotal).filter(ClientTotal.client ==
auth_client_name).order_by(ClientTotal.id.desc()).all()

for rbac in result_by_auth_client:
    print(rbac.id) 
session.close()

For this case you could use interfaces from default library (java 1.8):

java.util.function.BiConsumer
java.util.function.BiFunction

There is a small (not the best) example of default method in interface:

default BiFunction<File, String, String> getFolderFileReader() {
    return (directory, fileName) -> {
        try {
            return FileUtils.readFile(directory, fileName);
        } catch (IOException e) {
            LOG.error("Unable to read file {} in {}.", fileName, directory.getAbsolutePath(), e);
        }
        return "";
    };
}}

I had a similar problem. I needed to wait until my document was ready but also until all Ajax calls had finished. The second condition proved to be difficult to detect. In the end I checked for active Ajax calls and it worked.

Javascript:

return (document.readyState == 'complete' && jQuery.active == 0)

Full C# method:

private void WaitUntilDocumentIsReady(TimeSpan timeout)
{
    var javaScriptExecutor = WebDriver as IJavaScriptExecutor;
    var wait = new WebDriverWait(WebDriver, timeout);            

    // Check if document is ready
    Func<IWebDriver, bool> readyCondition = webDriver => javaScriptExecutor
        .ExecuteScript("return (document.readyState == 'complete' && jQuery.active == 0)");
    wait.Until(readyCondition);
}

If you use a Language Resource file to set the labels in your application you need to set the its value:

CultureInfo customCulture = new CultureInfo("en-US");
Languages.Culture = customCulture;

How about:

prog1 & prog2 && fg

This will:

1. Start prog1.
2. Send it to background, but keep printing its output.
3. Start prog2, and keep it in foreground, so you can close it with ctrl-c.
4. When you close prog2, you'll return to prog1's foreground, so you can also close it with ctrl-c.

Use android.util.Log and the static methods defined there (e.g., e(), w()).

With the following small function, digging into a tree-shaped dictionary becomes quite easy:

def dig(tree, path):
    for key in path.split("."):
        if isinstance(tree, dict) and tree.get(key):
            tree = tree[key]
        else:
            return None
    return tree

Now, dig(mydict, "Apple.Mexican") returns 10, while dig(mydict, "Grape") yields the subtree {'Arabian':'25','Indian':'20'}. If a key is not contained in the dictionary, dig returns None.

Note that you can easily change (or even parameterize) the separator char from '.' to '/', '|' etc.

You would typically do something like:

protected void btnClose_Click(object sender, EventArgs e)
{
    ClientScript.RegisterStartupScript(typeof(Page), "closePage", "window.close();", true);
}

However, keep in mind that different things will happen in different scenerios. Firefox won't let you close a window that wasn't opened by you (opened with window.open()).

IE7 will prompt the user with a "This page is trying to close (Yes | No)" dialog.

In any case, you should be prepared to deal with the window not always closing!

One fix for the 2 above issues is to use:

protected void btnClose_Click(object sender, EventArgs e) {
    ClientScript.RegisterStartupScript(typeof(Page), "closePage", "window.open('close.html', '_self', null);", true);
}

And create a close.html:

<html><head>
 <title></title>
 <script language="javascript" type="text/javascript">
     var redirectTimerId = 0;
     function closeWindow()
     {
         window.opener = top;
         redirectTimerId = window.setTimeout('redirect()', 2000);
         window.close(); 
     }

     function stopRedirect()
     {
         window.clearTimeout(redirectTimerId);
     }

     function redirect()
     {
         window.location = 'default.aspx';
     }
 </script>
 </head>
 <body onload="closeWindow()" onunload="stopRedirect()" style="">
     <center><h1>Please Wait...</h1></center>
 </body></html>

Note that close.html will redirect to default.aspx if the window does not close after 2 sec for some reason.

The correct pattern is to call the Redirect overload with endResponse=false and make a call to tell the IIS pipeline that it should advance directly to the EndRequest stage once you return control:

Response.Redirect(url, false);
Context.ApplicationInstance.CompleteRequest();

This blog post from Thomas Marquardt provides additional details, including how to handle the special case of redirecting inside an Application_Error handler.

This worked great for me

$this->db->where('sell_date BETWEEN "'. date('Y-m-d', strtotime($start_date)). '" and "'. date('Y-m-d', strtotime($end_date)).'"');

will I get the same results?

Not really. I don't know of a workaround for PHP 5.2, though.

What is the difference between new self and new static?

self refers to the same class in which the new keyword is actually written.

static, in PHP 5.3's late static bindings, refers to whatever class in the hierarchy you called the method on.

In the following example, B inherits both methods from A. The self invocation is bound to A because it's defined in A's implementation of the first method, whereas static is bound to the called class (also see get_called_class()).

class A {
    public static function get_self() {
        return new self();
    }

    public static function get_static() {
        return new static();
    }
}

class B extends A {}

echo get_class(B::get_self());  // A
echo get_class(B::get_static()); // B
echo get_class(A::get_self()); // A
echo get_class(A::get_static()); // A

Checking the owner of /dev/console seems to work well.

stat -f "%Su" /dev/console

To be efficient, and random, it might be best to have two different queries.

Something like...

SELECT table_id FROM table

Then, in your chosen language, pick a random id, then pull that row's data.

SELECT * FROM table WHERE table_id = $rand_id

But that's not really a good idea if you're expecting to have lots of rows in the table. It would be better if you put some kind of limit on what you randomly select from. For publications, maybe randomly pick from only items posted within the last year.

Assuming that you're working with a class named MyClass, the following should work:

MyClass.class.getClassLoader();

Whether or not you can get the on-disk location of the .class file is dependent on the classloader itself. For example, if you're using something like BCEL, a certain class may not even have an on-disk representation.

I think that the solution of @Azimuts (https://stackoverflow.com/a/33375677/6503697) is for HTTP only connection. For FTPS connection you can use Bouncy Castle with org.apache.commons.net.ftp.FTPSClient without the need for rewrite FTPS protocol.

I have a program running on JRE 1.6.0_04 and I can not update the JRE.

The program has to connect to an FTPS server that work only with TLS 1.2 (IIS server).

I struggled for days and finally I have understood that there are few versions of bouncy castle library right in my use case: bctls-jdk15on-1.60.jar and bcprov-jdk15on-1.60.jar are ok, but 1.64 versions are not.

The version of apache commons-net is 3.1 .

Following is a small snippet of code that should work:

import java.io.ByteArrayOutputStream;
import java.security.SecureRandom;
import java.security.Security;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPReply;
import org.apache.commons.net.ftp.FTPSClient;

import org.junit.Test;


public class FtpsTest {

// Create a trust manager that does not validate certificate chains

    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }

    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }
} };

@Test public void test() throws Exception {


    Security.insertProviderAt(new BouncyCastleProvider(), 1);
    Security.addProvider(new BouncyCastleJsseProvider());


    SSLContext sslContext = SSLContext.getInstance("TLS", new BouncyCastleJsseProvider());
    sslContext.init(null, trustAllCerts, new SecureRandom());
    org.apache.commons.net.ftp.FTPSClient ftpClient = new FTPSClient(sslContext);
    ByteArrayOutputStream out = null;
    try {

        ftpClient.connect("hostaname", 21);
        if (!FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) {
            String msg = "Il server ftp ha rifiutato la connessione.";
            throw new Exception(msg);
        }
        if (!ftpClient.login("username", "pwd")) {
            String msg = "Il server ftp ha rifiutato il login con username:  username  e pwd:  password  .";
            ftpClient.disconnect();
            throw new Exception(msg);
        }


        ftpClient.enterLocalPassiveMode();
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        ftpClient.setDataTimeout(60000);
        ftpClient.execPBSZ(0); // Set protection buffer size
        ftpClient.execPROT("P"); // Set data channel protection to private
        int bufSize = 1024 * 1024; // 1MB
        ftpClient.setBufferSize(bufSize);
        out = new ByteArrayOutputStream(bufSize);
        ftpClient.retrieveFile("remoteFileName", out);
        out.toByteArray();
    }
    finally {
        if (out != null) {
            out.close();
        }
        ftpClient.disconnect();

    }

}

}

To append to an array, just use the += operator.

$Target += $TargetObject

Also, you need to declare $Target = @() before your loop because otherwise, it will empty the array every loop.

Yes, Ruby has very similar array-slicing syntax to Python. Here is the ri documentation for the array index method:

--------------------------------------------------------------- Array#[]
     array[index]                -> obj      or nil
     array[start, length]        -> an_array or nil
     array[range]                -> an_array or nil
     array.slice(index)          -> obj      or nil
     array.slice(start, length)  -> an_array or nil
     array.slice(range)          -> an_array or nil
------------------------------------------------------------------------
     Element Reference---Returns the element at index, or returns a 
     subarray starting at start and continuing for length elements, or 
     returns a subarray specified by range. Negative indices count 
     backward from the end of the array (-1 is the last element). 
     Returns nil if the index (or starting index) are out of range.

        a = [ "a", "b", "c", "d", "e" ]
        a[2] +  a[0] + a[1]    #=> "cab"
        a[6]                   #=> nil
        a[1, 2]                #=> [ "b", "c" ]
        a[1..3]                #=> [ "b", "c", "d" ]
        a[4..7]                #=> [ "e" ]
        a[6..10]               #=> nil
        a[-3, 3]               #=> [ "c", "d", "e" ]
        # special cases
        a[5]                   #=> nil
        a[6, 1]                #=> nil
        a[5, 1]                #=> []
        a[5..10]               #=> []

For those wanting a more secure way to create a random byte array, yes the most secure way is:

byte[] bytes = new byte[20];
SecureRandom.getInstanceStrong().nextBytes(bytes);

BUT your threads might block if there is not enough randomness available on the machine, depending on your OS. The following solution will not block:

SecureRandom random = new SecureRandom();
byte[] bytes = new byte[20];
random.nextBytes(bytes);

This is because the first example uses /dev/random and will block while waiting for more randomness (generated by a mouse/keyboard and other sources). The second example uses /dev/urandom which will not block.

yourToolTip = new ToolTip();
//The below are optional, of course,

yourToolTip.ToolTipIcon = ToolTipIcon.Info;
yourToolTip.IsBalloon = true;
yourToolTip.ShowAlways = true;

yourToolTip.SetToolTip(lblYourLabel,"Oooh, you put your mouse over me.");

itertools is ideally suited for this:

itertools.chain.from_iterable((''.join(l)
                               for l in itertools.product(charset, repeat=i))
                              for i in range(1, maxlen + 1))

Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

Example -

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

The above should set the default encoding as utf-8 .

$location.search() will work only with HTML5 mode turned on and only on supporting browser.

This will work always:

$window.location.search

If you are using jQuery you can easily check the type of any element.

    function(elementID){    
    var type = $(elementId).attr('type');
    if(type == "text") //inputBox
     console.log("input text" + $(elementId).val().size());
   }

similarly you can check the other types and take appropriate action.

Using the ironRuby interperter you have the full .net platform, meaning you can code Winforms and WPF(I have only tried Winforms). It is potentially cross platform since the mono platform exist

Use this query:

UPDATE `table` SET date_date=now();

Sample code can be:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE `table` SET date_date=now()");

mysql_close($con);
?>

Maybe you should have a look at Mapquests Traffic API: http://www.mapquestapi.com/traffic/

The webservice is unfortunately only available for some citys in the US, I think. But probably it solves your problem.

Node.js 10.5+ supports worker threads as experimental feature (you can use it with --experimental-worker flag enabled): https://nodejs.org/api/worker_threads.html

So, the rule is:

• if you need to do I/O bound ops, then use the internal mechanism (aka callback/promise/async-await)
• if you need to do CPU bound ops, then use worker threads.

Worker threads are intended to be long-living threads, meaning you spawn a background thread and then you communicate with it via message passing.

Otherwise, if you need to execute a heavy CPU load with an anonymous function, then you can go with https://github.com/wilk/microjob, a tiny library built around worker threads.

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:
    local('Green Web'),
    local('GreenWeb-Regular'),
    url('GreenWeb.ttf');
}

There is a more elaborate description of what to do here.

Another way of doing the same could be using the Gson Class

String filename = "path/to/file/abc.json";
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
SampleClass data = gson.fromJson(reader, SampleClass.class);

This will give an object obtained after parsing the json string to work with.

>>> list(x for x in string.letters if x in (y for y in "BigMan on campus"))
['a', 'c', 'g', 'i', 'm', 'n', 'o', 'p', 's', 'u', 'B', 'M']

I guess your code relates to Windows Forms.
You call BeginInvoke if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)

If BeginInvoke is called for Delegate type the delegate is just invoked asynchronously.
(Invoke for the sync version.)

If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task with the according context. (TaskScheduler.FromCurrentSynchronizationContext())

And to add a little to already said by others: Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var with lambdas: compiler needs a hint.

UPDATE:

this requires .Net v4.0 and higher

// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);

// also can be called anywhere. Task  will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked) 
task.Start(scheduler);

If you started the task from other thread and need to wait for its completition task.Wait() will block calling thread till the end of the task.

yourStringStream.str()

for kotlin, it works for me

priceTextView.textSize = 12f

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

Slightly twisted, but an iterator block to do it:

public static IEnumerable<string> Lines(this string Text)
{
    int cIndex = 0;
    int nIndex;
    while ((nIndex = Text.IndexOf(Environment.NewLine, cIndex + 1)) != -1)
    {
        int sIndex = (cIndex == 0 ? 0 : cIndex + 1);
        yield return Text.Substring(sIndex, nIndex - sIndex);
        cIndex = nIndex;
    }
    yield return Text.Substring(cIndex + 1);
}

You can then call:

var result = input.Lines().ToArray();

As for current Chrome version (56) you can't remove it yet. Solution provided in other posts leads to overflowing some part of the video.

I've found another solution - you can make the preceding button to overlap the download button and simply cover it, by using this technique:

video::-webkit-media-controls-fullscreen-button {
   margin-right: -48px;
   z-index: 10;
   position: relative;
   background: #fafafa;
   background-image: url(https://image.flaticon.com/icons/svg/151/151926.svg);
   background-size: 35%;
   background-position: 50% 50%;
   background-repeat: no-repeat;
}

Example: https://jsfiddle.net/dk4q6hh2/

PS You might want to customise the icon, since it's for example only.

An alternative to the accepted answer that fits in the first line:

#!/bin/bash -e

cd some_dir  

./configure --some-flags  

make  

make install

This solution worked well for me: http://www.apachefriends.org/f/viewtopic.php?f=17&t=50902&p=196185#p196185

Edit /opt/lampp/etc/extra/httpd-xampp.conf and adding Require all granted line at bottom of block <Directory "/opt/lampp/phpmyadmin"> to have the following code:

<Directory "/opt/lampp/phpmyadmin">

  Order allow,deny
  Allow from all
  Require all granted
</Directory>

x = ['1', '2', '3']
s = f"{x[0]} BLAH {x[1]} FOO {x[2]} BAR"
print(s)

The output is

1 BLAH 2 FOO 3 BAR

As doc says also keep in mind the correct value combination:

The setting must be one of the values listed in the following table, or a combination of one "state..." value plus one "adjust..." value. Setting multiple values in either group — multiple "state..." values, for example — has undefined results. Individual values are separated by a vertical bar (|). For example:

<activity android:windowSoftInputMode="stateVisible|adjustResize" . . . >

No this is not enough (in some specific cases)! By default PDO uses emulated prepared statements when using MySQL as a database driver. You should always disable emulated prepared statements when using MySQL and PDO:

$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

Another thing that always should be done it set the correct encoding of the database:

$dbh = new PDO('mysql:dbname=dbtest;host=127.0.0.1;charset=utf8', 'user', 'pass');

Also see this related question: How can I prevent SQL injection in PHP?

Also note that that only is about the database side of the things you would still have to watch yourself when displaying the data. E.g. by using htmlspecialchars() again with the correct encoding and quoting style.

You can combine Adam & Greg's alias and dot approaches to make something that can be more dynamic—

alias project=". project"

Now running the project alias will execute the project script in the current shell as opposed to the subshell.

This worked for me in newer browsers:

You Can Use The Simplest Method

<?php
function make_thumb($src, $dest, $desired_width) {

    /* read the source image */
    $source_image = imagecreatefromjpeg($src);
    $width = imagesx($source_image);
    $height = imagesy($source_image);

    /* find the "desired height" of this thumbnail, relative to the desired width  */
    $desired_height = floor($height * ($desired_width / $width));

    /* create a new, "virtual" image */
    $virtual_image = imagecreatetruecolor($desired_width, $desired_height);

    /* copy source image at a resized size */
    imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);

    /* create the physical thumbnail image to its destination */
    imagejpeg($virtual_image, $dest);
}

$src="1494684586337H.jpg";
$dest="new.jpg";
$desired_width="200";
make_thumb($src, $dest, $desired_width);
?>

In a function call the single star turns a list into seperate arguments (e.g. zip(*x) is the same as zip(x1,x2,x3) if x=[x1,x2,x3]) and the double star turns a dictionary into seperate keyword arguments (e.g. f(**k) is the same as f(x=my_x, y=my_y) if k = {'x':my_x, 'y':my_y}.

In a function definition it's the other way around: the single star turns an arbitrary number of arguments into a list, and the double start turns an arbitrary number of keyword arguments into a dictionary. E.g. def foo(*x) means "foo takes an arbitrary number of arguments and they will be accessible through the list x (i.e. if the user calls foo(1,2,3), x will be [1,2,3])" and def bar(**k) means "bar takes an arbitrary number of keyword arguments and they will be accessible through the dictionary k (i.e. if the user calls bar(x=42, y=23), k will be {'x': 42, 'y': 23})".

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

Why don't you simply hide, append, then show, like this:

<div id="parent1" style="  width: 300px; height: 300px; background-color: yellow;">
    <div id="child" style=" width: 100px; height: 100px; background-color: red;"></div>
</div>


<div id="parent2" style="  width: 300px; height: 300px; background-color: green;">
</div>

<input id="mybutton" type="button" value="move">

<script>
    $("#mybutton").click(function(){
        $('#child').hide(1000, function(){
            $('#parent2').append($('#child'));
            $('#child').show(1000);
        });

    });
</script>

I ran into the same problem because I set the http_proxy and https_proxy environment variables. But occasionally, I connect to a different network and need to bypass the proxy temporarily. The easiest way to do this (without changing the environment variables) is:

curl --noproxy '*' stackoverflow.com

From the manual: "The only wildcard is a single * character, which matches all hosts, and effectively disables the proxy."

The * character is quoted so that it is not erroneously expanded by the shell.

Your submit button doesn't have a name. Add name="submit" to your submit button.

If you view source on the form in the browser, you'll see how it submits to self - the form's action attribute will contain the name of the current script - therefore when the form submits, it submits to itself. Edit for vanity sake!

I rely heavily on commands like this.

python -c 'import sys; print(sys.maxsize)'

Max int returned: 9223372036854775807

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

c_str() converts a C++ string into a C-style string which is essentially a null terminated array of bytes. You use it when you want to pass a C++ string into a function that expects a C-style string (e.g. a lot of the Win32 API, POSIX style functions, etc).

Here's a comprehensive yet non-exhaustive list of examples of list operations and whether or not they are thread safe. Hoping to get an answer regarding the obj in a_list language construct here.

max-width is definitely not well supported. If you're going to use it, use it in a media query in your style tag. ios, android, and windows phone default mail all support them. (gmail and outlook mobile don't)

http://www.campaignmonitor.com/guides/mobile/targeting/

Look at the starbucks example at the bottom

Depending on the admin settings, you may have to specify your old password using the REPLACE option

alter user <username> identified by <newpassword> replace <oldpassword> 

As said Will Wagner, in old version of jsp you should always use c:out to output dynamic text.

Moreover, using this syntax:

<c:out value="${person.name}">No name</c:out>

you can display the text "No name" when name is null.

Three double quotes: " " " x " " " = "x" Excel will auto change to one double quote. e.g.:

=CONCATENATE("""x"""," hi")  

= "x" hi

To add to wflynny's answer above, you can find the available colormaps here

Example:

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.jet)

or alternatively,

plt.scatter(x, y, c=t, cmap='jet')

class async_file_get_contents extends Thread{
    public $ret;
    public $url;
    public $finished;
        public function __construct($url) {
        $this->finished=false;
        $this->url=$url;
    }
        public function run() {
        $this->ret=file_get_contents($this->url);
        $this->finished=true;
    }
}
$afgc=new async_file_get_contents("http://example.org/file.ext");

The memory must be configured in several places.
Set memory_limit to 512M:

sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini

Restart service:

sudo service service php5-fpm restart
sudo service service nginx restart

or

sudo service apache2 restart

Finally it should solve the problem of the memory_limit

It depends. On MySQL an index is created if you don't create it on your own:

MySQL requires that foreign key columns be indexed; if you create a table with a foreign key constraint but no index on a given column, an index is created.

Source: https://dev.mysql.com/doc/refman/8.0/en/constraint-foreign-key.html

The same for MySQL 5.6 eh.

I suggest using the Segment analytics library and following our Angular quickstart guide. You’ll be able to track page visits and track user behavior actions with a single API. If you have an SPA, you can allow the RouterOutlet component to handle when the page renders and use ngOnInit to invoke page calls. The example below shows one way you could do this:

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {
  ngOnInit() {
    window.analytics.page('Home');
  }
}

I’m the maintainer of https://github.com/segmentio/analytics-angular. With Segment, you’ll be able to switch different destinations on-and-off by the flip of a switch if you are interested in trying multiple analytics tools (we support over 250+ destinations) without having to write any additional code.

Why not just use CSS?

.parent:hover .child, .parent.hover .child { display: block; }

and then add JS for IE6 (inside a conditional comment for instance) which doesn't support :hover properly:

jQuery('.parent').hover(function () {
    jQuery(this).addClass('hover');
}, function () {
    jQuery(this).removeClass('hover');
});

Here's a quick example: Fiddle

First of all, @Fetch(FetchMode.JOIN) and @ManyToOne(fetch = FetchType.LAZY) are antagonistic because @Fetch(FetchMode.JOIN) is equivalent to the JPA FetchType.EAGER.

Eager fetching is rarely a good choice, and for predictable behavior, you are better off using the query-time JOIN FETCH directive:

public interface PlaceRepository extends JpaRepository<Place, Long>, PlaceRepositoryCustom {

    @Query(value = "SELECT p FROM Place p LEFT JOIN FETCH p.author LEFT JOIN FETCH p.city c LEFT JOIN FETCH c.state where p.id = :id")
    Place findById(@Param("id") int id);
}

public interface CityRepository extends JpaRepository<City, Long>, CityRepositoryCustom { 
    @Query(value = "SELECT c FROM City c LEFT JOIN FETCH c.state where c.id = :id")   
    City findById(@Param("id") int id);
}

TLDR:

So what I did was to have the standard src/main/resources/application.properties and also a src/test/resources/application-default.properties where i override some settings for ALL my tests.

Whole Story

I ran into the same problem and was not using profiles either so far. It seemed to be bothersome to have to do it now and remember declaring the profile -- which can be easily forgotten.

The trick is, to leverage that a profile specific application-<profile>.properties overrides settings in the general profile. See https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-profile-specific-properties.

Just in case someone stumbles upon this like I did and doesn't realise, the two variations above are for different use cases.

The following:

.blue-border, .background {
    border: 1px solid #00f;
    background: #fff;
}

is for when you want to add styles to elements that have either the blue-border or background class, for example:

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

would all get a blue border and white background applied to them.

However, the accepted answer is different.

.blue-border.background {
    border: 1px solid #00f;
    background: #fff;
}

This applies the styles to elements that have both classes so in this example only the <div> with both classes should get the styles applied (in browsers that interpret the CSS properly):

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

So basically think of it like this, comma separating applies to elements with one class OR another class and dot separating applies to elements with one class AND another class.

You can actually disable all database constraints in a single SQL command and the re-enable them calling another single command. See:

• Can foreign key constraints be temporarily disabled using TSQL?

I am currently working with SQL Server 2005 but I am almost sure that this approach worked with SQL 2000 as well

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

In case any one wants it in Kotlin :

val dialogBuilder = AlertDialog.Builder(this)
// ...Irrelevant code for customizing the buttons and title
val dialogView = layoutInflater.inflate(R.layout.alert_label_editor, null)
dialogBuilder.setView(dialogView)

val editText =  dialogView.findViewById(R.id.label_field)
editText.setText("test label")
val alertDialog = dialogBuilder.create()
alertDialog.show()

Reposted @user370305's answer.

instead of localhost of '0.0.0.0', use local network address as host in case of both - the server and the client - code.

host = '192.168.12.12' port = 12345

use this host address when binding and connecting to the socket.

server.bind((host, port)) client.connect((host, port))

this change solved the issue for me.

I found that for me the best permanent solution to stay up-to-date under Linux was to install the R-patched project. This will keep your R installation up-to-date, and you needn't even move your packages between installations (which is described in RyanStochastic's answer).

For openSUSE, see the instructions here.

i think the problem is that there is no data in the success-function because the request breaks up with an 401 error in your case and thus has no success.

if you use

$.ajax({
        url: "https://app.asana.com/-/api/0.1/workspaces/",
        type: 'GET',
         error: function (xhr, ajaxOptions, thrownError) {
    alert(xhr.status);
    alert(thrownError);
  }
    });

there will be your 401 code i think (this link says so)

You can use GNU GetOpt (LGPL) or one of the various C++ ports, such as getoptpp (GPL).

A simple example using GetOpt of what you want (prog [-ab] input) is the following:

// C Libraries:
#include <string>
#include <iostream>
#include <unistd.h>

// Namespaces:
using namespace std;

int main(int argc, char** argv) {
    int opt;
    string input = "";
    bool flagA = false;
    bool flagB = false;

    // Retrieve the (non-option) argument:
    if ( (argc <= 1) || (argv[argc-1] == NULL) || (argv[argc-1][0] == '-') ) {  // there is NO input...
        cerr << "No argument provided!" << endl;
        //return 1;
    }
    else {  // there is an input...
        input = argv[argc-1];
    }

    // Debug:
    cout << "input = " << input << endl;

    // Shut GetOpt error messages down (return '?'):

Which whitespace character? The empty string is pretty unambiguous - it's a sequence of 0 characters. However, " ", "\t" and "\n" are all strings containing a single character which is characterized as whitespace.

If you just mean a space, use a space. If you mean some other whitespace character, there may well be a custom escape sequence for it (e.g. "\t" for tab) or you can use a Unicode escape sequence ("\uxxxx"). I would discourage you from including non-ASCII characters in your source code, particularly whitespace ones.

EDIT: Now that you've explained what you want to do (which should have been in your question to start with) you'd be better off using Regex.Split with a regular expression of \s which represents whitespace:

Regex regex = new Regex(@"\s");
string[] bits = regex.Split(text.ToLower());

See the Regex Character Classes documentation for more information on other character classes.

just set -Dlog4j.configuration=file:log4j.properties worked for me.

log4j then looks for the file log4j.properties in the current working directory of the application.

Remember that log4j.configuration is a URL specification, so add 'file:' in front of your log4j.properties filename if you want to refer to a regular file on the filesystem, i.e. a file not on the classpath!

Initially I specified -Dlog4j.configuration=log4j.properties. However that only works if log4j.properties is on the classpath. When I copied log4j.properties to main/resources in my project and rebuild so that it was copied to the target directory (maven project) this worked as well (or you could package your log4j.properties in your project jars, but that would not allow the user to edit the logger configuration!).

Use,

var url = $(this).attr('href');
window.open(url, '_blank');

Update:the href is better off being retrieved with prop since it will return the full url and it's slightly faster.

var url = $(this).prop('href');

if (typeof x.key != "undefined") {

}

Because

if (x.key)

fails if x.key resolves to false (for example, x.key = "").

I had this issue today. I'll add a workaround that uses <script defer> as I didn't see the other answers mention it.

//on a JS file somewhere (i.e partial-view-caller.js)
(() => <your partial view script>)();

//in your Partial View
<script src="~/partial-view-caller.js" defer></script>

//you can actually just straight call your partial view script living in an external file - I just prefer having an initialization method :)

Code above is an excerpt from a quick post I made about this question.

You need to seed the random number generator, from man 3 rand

If no seed value is provided, the rand() function is automatically seeded with a value of 1.

and

The srand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned by rand(). These sequences are repeatable by calling srand() with the same seed value.

e.g.

srand(time(NULL));

Well, your whole code can be limited to:

foreach $line (@lines){
        $strings{$1}++ if $line =~ m|my regex|;
}

If the value is not there, ++ operator will assume it to be 0 (and then increment to 1). If it is already there - it will simply be incremented.

Try to add the suggested code to the TextChanged event:

private void textBox1_TextChanged(object sender, EventArgs e)
{
  textBox1.SelectionStart = textBox1.Text.Length;
  textBox1.ScrollToCaret();
}

In Netbeans, you can instruct Maven to check javadoc on every project open :

Tools | Options | Java icon | Maven tab | Dependencies category | Check Javadoc drop down set to Every Project Open.

Close and reopen Netbeans and you will see Maven download javadocs in the status bar.

We can use the core java stuff alone to read the CVS file column by column. Here is the sample code I have wrote for my requirement. I believe that it will help for some one.

 BufferedReader br = new BufferedReader(new FileReader(csvFile));
    String line = EMPTY;
    int lineNumber = 0;

    int productURIIndex = -1;
    int marketURIIndex = -1;
    int ingredientURIIndex = -1;
    int companyURIIndex = -1;

    // read comma separated file line by line
    while ((line = br.readLine()) != null) {
        lineNumber++;
        // use comma as line separator
        String[] splitStr = line.split(COMMA);
        int splittedStringLen = splitStr.length;

        // get the product title and uri column index by reading csv header
        // line
        if (lineNumber == 1) {
            for (int i = 0; i < splittedStringLen; i++) {
                if (splitStr[i].equals(PRODUCTURI_TITLE)) {
                    productURIIndex = i;
                    System.out.println("product_uri index:" + productURIIndex);
                }

                if (splitStr[i].equals(MARKETURI_TITLE)) {
                    marketURIIndex = i;
                    System.out.println("marketURIIndex:" + marketURIIndex);
                }

                if (splitStr[i].equals(COMPANYURI_TITLE)) {
                    companyURIIndex = i;
                    System.out.println("companyURIIndex:" + companyURIIndex);
                }

                if (splitStr[i].equals(INGREDIENTURI_TITLE)) {
                    ingredientURIIndex = i;
                    System.out.println("ingredientURIIndex:" + ingredientURIIndex);
                }
            }
        } else {
            if (splitStr != null) {
                String conditionString = EMPTY;
                // avoiding arrayindexoutboundexception when the line
                // contains only ,,,,,,,,,,,,,
                for (String s : splitStr) {
                    conditionString = s;
                }
                if (!conditionString.equals(EMPTY)) {
                    if (productURIIndex != -1) {
                        productCVSUriList.add(splitStr[productURIIndex]);
                    }
                    if (companyURIIndex != -1) {
                        companyCVSUriList.add(splitStr[companyURIIndex]);

                        marketCVSUriList.add(splitStr[marketURIIndex]);
                    }
                    if (ingredientURIIndex != -1) {

You may use YQL however yahoo.finance.* tables are not the core yahoo tables. It is an open data table which uses the 'csv api' and converts it to json or xml format. It is more convenient to use but it's not always reliable. I could not use it just a while ago because it the table hits its storage limit or something...

You may use this php library to get historical data / quotes using YQL https://github.com/aygee/php-yql-finance

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

First, here are the results for what currently are the latest versions of Python 2 & 3:

I also ran it with a much larger 10 MiB test file (which took nearly an hour to run) and got performance results which were comparable to those shown above.

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

Below is the solution that worked for me. This function is in a controller and will return a structured array of all the error messages and the field that caused them.

Symfony 2.0:

private function getErrorMessages(\Symfony\Component\Form\Form $form) {
    $errors = array();
    foreach ($form->getErrors() as $key => $error) {
        $template = $error->getMessageTemplate();
        $parameters = $error->getMessageParameters();

        foreach($parameters as $var => $value){
            $template = str_replace($var, $value, $template);
        }

        $errors[$key] = $template;
    }
    if ($form->hasChildren()) {
        foreach ($form->getChildren() as $child) {
            if (!$child->isValid()) {
                $errors[$child->getName()] = $this->getErrorMessages($child);
            }
        }
    }

    return $errors;
}

Symfony 2.1 and newer:

private function getErrorMessages(\Symfony\Component\Form\Form $form) {      
    $errors = array();

    if ($form->hasChildren()) {
        foreach ($form->getChildren() as $child) {
            if (!$child->isValid()) {
                $errors[$child->getName()] = $this->getErrorMessages($child);
            }
        }
    } else {
        foreach ($form->getErrors() as $key => $error) {
            $errors[] = $error->getMessage();
        }   
    }

    return $errors;
}

1. Go to Tools.
2. Extensions and Updates.
3. Update Nuget and any other important feature.
4. Restart.

Done.

I need to make a POST request via Curl from the command line. Data for this request is located in a file...

All you need to do is have the --data argument start with a @:

curl -H "Content-Type: text/xml" --data "@path_of_file" host:port/post-file-path

For example, if you have the data in a file called stuff.xml then you would do something like:

curl -H "Content-Type: text/xml" --data "@stuff.xml" host:port/post-file-path

The stuff.xml filename can be replaced with a relative or full path to the file: @../xml/stuff.xml, @/var/tmp/stuff.xml, ...

If you are trying to decipher info MS puts on their patching site such as https://technet.microsoft.com/en-us/library/security/ms17-010.aspx

you will need a combo such as:

$name=(Get-WmiObject Win32_OperatingSystem).caption $bit=(Get-WmiObject Win32_OperatingSystem).OSArchitecture $ver=(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").ReleaseId Write-Host $name, $bit, $ver

Microsoft Windows 10 Home 64-bit 1703

this worked for me:-

<?php echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>'; ?>

Not quite sure what the 300 is supposed to mean? Miss typo? However for iframes it would be best to use CSS :) - Ive found befor when importing youtube videos that it ignores inline things.

There are several ways to create an array of strings in C. If all the strings are going to be the same length (or at least have the same maximum length), you simply declare a 2-d array of char and assign as necessary:

char strs[NUMBER_OF_STRINGS][STRING_LENGTH+1];
...
strcpy(strs[0], aString); // where aString is either an array or pointer to char
strcpy(strs[1], "foo");

You can add a list of initializers as well:

char strs[NUMBER_OF_STRINGS][STRING_LENGTH+1] = {"foo", "bar", "bletch", ...};

This assumes the size and number of strings in the initializer match up with your array dimensions. In this case, the contents of each string literal (which is itself a zero-terminated array of char) are copied to the memory allocated to strs. The problem with this approach is the possibility of internal fragmentation; if you have 99 strings that are 5 characters or less, but 1 string that's 20 characters long, 99 strings are going to have at least 15 unused characters; that's a waste of space.

Instead of using a 2-d array of char, you can store a 1-d array of pointers to char:

char *strs[NUMBER_OF_STRINGS];

Note that in this case, you've only allocated memory to hold the pointers to the strings; the memory for the strings themselves must be allocated elsewhere (either as static arrays or by using malloc() or calloc()). You can use the initializer list like the earlier example:

char *strs[NUMBER_OF_STRINGS] = {"foo", "bar", "bletch", ...};

Instead of copying the contents of the string constants, you're simply storing the pointers to them. Note that string constants may not be writable; you can reassign the pointer, like so:

strs[i] = "bar";
strs[i] = "foo"; 

But you may not be able to change the string's contents; i.e.,

strs[i] = "bar";
strcpy(strs[i], "foo");

may not be allowed.

You can use malloc() to dynamically allocate the buffer for each string and copy to that buffer:

strs[i] = malloc(strlen("foo") + 1);
strcpy(strs[i], "foo");

BTW,

char (*a[2])[14];

Declares a as a 2-element array of pointers to 14-element arrays of char.

There's a good answer here:

function toTitleCase(str) {
    return str.replace(/\w\S*/g, function(txt){
        return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
    });
}

or in ES6:

var text = "foo bar loo zoo moo";
text = text.toLowerCase()
    .split(' ')
    .map((s) => s.charAt(0).toUpperCase() + s.substring(1))
    .join(' ');

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

Sun's java 1.4 has the following arguments to control memory size:

-Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:

           -Xms6291456
           -Xms6144k
           -Xms6m

-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:

           -Xmx83886080
           -Xmx81920k
           -Xmx80m

Configuring Identity to your existing project is not hard thing. You must install some NuGet package and do some small configuration.

First install these NuGet packages with Package Manager Console:

PM> Install-Package Microsoft.AspNet.Identity.Owin 
PM> Install-Package Microsoft.AspNet.Identity.EntityFramework
PM> Install-Package Microsoft.Owin.Host.SystemWeb 

Add a user class and with IdentityUser inheritance:

public class AppUser : IdentityUser
{
    //add your custom properties which have not included in IdentityUser before
    public string MyExtraProperty { get; set; }  
}

Do same thing for role:

public class AppRole : IdentityRole
{
    public AppRole() : base() { }
    public AppRole(string name) : base(name) { }
    // extra properties here 
}

Change your DbContext parent from DbContext to IdentityDbContext<AppUser> like this:

public class MyDbContext : IdentityDbContext<AppUser>
{
    // Other part of codes still same 
    // You don't need to add AppUser and AppRole 
    // since automatically added by inheriting form IdentityDbContext<AppUser>
}

If you use the same connection string and enabled migration, EF will create necessary tables for you.

Optionally, you could extend UserManager to add your desired configuration and customization:

public class AppUserManager : UserManager<AppUser>
{
    public AppUserManager(IUserStore<AppUser> store)
        : base(store)
    {
    }

    // this method is called by Owin therefore this is the best place to configure your User Manager
    public static AppUserManager Create(
        IdentityFactoryOptions<AppUserManager> options, IOwinContext context)
    {
        var manager = new AppUserManager(
            new UserStore<AppUser>(context.Get<MyDbContext>()));

        // optionally configure your manager
        // ...

        return manager;
    }
}

Since Identity is based on OWIN you need to configure OWIN too:

Add a class to App_Start folder (or anywhere else if you want). This class is used by OWIN. This will be your startup class.

namespace MyAppNamespace
{
    public class IdentityConfig
    {
        public void Configuration(IAppBuilder app)
        {
            app.CreatePerOwinContext(() => new MyDbContext());
            app.CreatePerOwinContext<AppUserManager>(AppUserManager.Create);
            app.CreatePerOwinContext<RoleManager<AppRole>>((options, context) =>
                new RoleManager<AppRole>(
                    new RoleStore<AppRole>(context.Get<MyDbContext>())));

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Home/Login"),
            });
        }
    }
}

Almost done just add this line of code to your web.config file so OWIN could find your startup class.

<appSettings>
    <!-- other setting here -->
    <add key="owin:AppStartup" value="MyAppNamespace.IdentityConfig" />
</appSettings>

Now in entire project you could use Identity just like any new project had already installed by VS. Consider login action for example

[HttpPost]
public ActionResult Login(LoginViewModel login)
{
    if (ModelState.IsValid)
    {
        var userManager = HttpContext.GetOwinContext().GetUserManager<AppUserManager>();
        var authManager = HttpContext.GetOwinContext().Authentication;

        AppUser user = userManager.Find(login.UserName, login.Password);
        if (user != null)
        {
            var ident = userManager.CreateIdentity(user, 
                DefaultAuthenticationTypes.ApplicationCookie);
            //use the instance that has been created. 
            authManager.SignIn(
                new AuthenticationProperties { IsPersistent = false }, ident);
            return Redirect(login.ReturnUrl ?? Url.Action("Index", "Home"));
        }
    }
    ModelState.AddModelError("", "Invalid username or password");
    return View(login);
}

You could make roles and add to your users:

public ActionResult CreateRole(string roleName)
{
    var roleManager=HttpContext.GetOwinContext().GetUserManager<RoleManager<AppRole>>();

    if (!roleManager.RoleExists(roleName))
        roleManager.Create(new AppRole(roleName));
    // rest of code
} 

You could also add a role to a user, like this:

UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");

By using Authorize you could guard your actions or controllers:

[Authorize]
public ActionResult MySecretAction() {}

or

[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}

You can also install additional packages and configure them to meet your requirement like Microsoft.Owin.Security.Facebook or whichever you want.

Note: Don't forget to add relevant namespaces to your files:

using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;

You could also see my other answers like this and this for advanced use of Identity.

Efficient is a word that depends on context. The solution to this problem depends on the amount of queries performed relative to the amount of insertions. Suppose you are inserting N numbers and K times towards the end you were interested in the median. The heap based algorithm's complexity would be O(N log N + K).

Consider the following alternative. Plunk the numbers in an array, and for each query, run the linear selection algorithm (using the quicksort pivot, say). Now you have an algorithm with running time O(K N).

Now if K is sufficiently small (infrequent queries), the latter algorithm is actually more efficient and vice versa.

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

Using Spring's SimpleJdbcTemplate, I got it when I tried to do this:

String sqlString = "select pwy_code from approver where university_id = '123'";
List<Map<String, Object>> rows = getSimpleJdbcTemplate().queryForList(sqlString, uniId);

• I had an argument to queryForList that didn't correspond to a question mark in the SQL. The first line should have been:

  String sqlString = "select pwy_code from approver where university_id = ?";
  

< stands for lesser than (<) symbol and, the > sign stands for greater than (>) symbol.

I have tried lots and lots of steps from different people posted on different websites. But none of them mention that I should add the certificate into the Trusted People keystore.

That's right, placing it under trusted CA is not enough for my case, I have to put the certs inside the Trusted People also.

That's:

1. Run MMC
2. Add Certificate Snap-in choose Local Computer
3. Expand Certificates(Local Computer) -> Trusted People -> Certificates
4. Right click All Task -> Import
5. Finish the wizard

To export the certificate:

1. Run IE as admin (right click, run as admin)
2. When prompted invalid cert, go ahead visit the website anyway
3. Click the certificate error near the address, click view certificate
4. Go to Details tab, click Copy To file
5. Save as *.cer file.

I'm on IE9, Windows 7

Use data-dismiss="modal". In the version of Bootstrap I am using v3.3.5, when data-dismiss="modal" is added to the desired button like shown below it calls my external Javascript (JQuery) function beautifully and magically closes the modal. Its soo Sweet, I was worried I would have to call some modal hide in another function and chain that to the real working function

 <a href="#" id="btnReleaseAll" class="btn btn-primary btn-default btn-small margin-right pull-right" data-dismiss="modal">Yes</a>

In some external script file, and in my doc ready there is of course a function for the click of that identifier ID

 $("#divExamListHeader").on('click', '#btnReleaseAll', function () {
               // Do DatabaseMagic Here for a call a MVC ActionResult

For those, like me, who did not have the possibility to use angular directive and were "stuck" outside of the angular scope, here is something that might help you.

After hours searching on the web and on the angular doc, I have created a class that compiles HTML, place it inside a targets, and binds it to a scope ($rootScope if there is no $scope for that element)

/**
 * AngularHelper : Contains methods that help using angular without being in the scope of an angular controller or directive
 */
var AngularHelper = (function () {
    var AngularHelper = function () { };

    /**
     * ApplicationName : Default application name for the helper
     */
    var defaultApplicationName = "myApplicationName";

    /**
     * Compile : Compile html with the rootScope of an application
     *  and replace the content of a target element with the compiled html
     * @$targetDom : The dom in which the compiled html should be placed
     * @htmlToCompile : The html to compile using angular
     * @applicationName : (Optionnal) The name of the application (use the default one if empty)
     */
    AngularHelper.Compile = function ($targetDom, htmlToCompile, applicationName) {
        var $injector = angular.injector(["ng", applicationName || defaultApplicationName]);

        $injector.invoke(["$compile", "$rootScope", function ($compile, $rootScope) {
            //Get the scope of the target, use the rootScope if it does not exists
            var $scope = $targetDom.html(htmlToCompile).scope();
            $compile($targetDom)($scope || $rootScope);
            $rootScope.$digest();
        }]);
    }

    return AngularHelper;
})();

It covered all of my cases, but if you find something that I should add to it, feel free to comment or edit.

Hope it will help.

Neither of the posted answers worked for me. Setting position: absolute for the child element did work however.

atm they are working on that issue https://github.com/firebase/quickstart-android/issues/4

when you send a notification from the Firebase console is uses your app icon by default, and the Android system will turn that icon solid white when in the notification bar.

If you are unhappy with that result you should implement FirebaseMessagingService and create the notifications manually when you receive a message. We are working on a way to improve this but for now that's the only way.

edit: with SDK 9.8.0 add to AndroidManifest.xml

<meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@drawable/my_favorite_pic"/>

Changing XAMPP Default Port: If you want to get XAMPP up and running, you should consider changing the port from the default 80 to say 7777.

• In the XAMPP Control Panel, click on the Apache – Config button which is located next to the ‘Logs’ button.

• Select ‘Apache (httpd.conf)’ from the drop down. (Notepad should open)

• Do Ctrl+F to find ’80’ and change line Listen 80 to Listen 7777

• Find again and change line ServerName localhost:80 to ServerName localhost:7777

• Save and re-start Apache. It should be running by now.

The only demerit to this technique is, you have to explicitly include the port number in the localhost url. Rather than http://localhost it becomes http://localhost:7777.

They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"

If you are using windows version nginx, you can try to kill all nginx process and restart it to see. I encountered same issue In my environment, but resolved it with this solution.

Full answer to the original question that was talking about a possible different path on local and remote is below

1. git fetch origin
2. git diff master -- [local-path] origin/master -- [remote-path]

Assuming the local path is docs/file1.txt and remote path is docs2/file1.txt, use git diff master -- docs/file1.txt origin/master -- docs2/file1.txt

This is adapted from GitHub help page here and Code-Apprentice answer above

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

1. Select File>New>Folder>Assets Folder

2. Click finish

3. Right click on assets and create a folder called fonts

4. Put your font file in assets > fonts

5. Use code below to change your textView's font

   TextView textView = (TextView) findViewById(R.id.textView);
   Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/yourfont.ttf");
   textView.setTypeface(typeface);
   

The NameValueCollection supports multiple string values under one key (which is also a string), but it is the only example I am aware of.

I tend to create constructs similar to the one in your example when I run into situations where I need that sort of functionality.

Just add a 0 or 1 token:

^-?[0-9]\d*(.\d+)?$

Here you go! Ready for Xcode 8 and Swift 3.

import UIKit

let mString = "This is a String that contains something to search."
let stringToSearchUpperCase = "String"
let stringToSearchLowerCase = "string"

mString.contains(stringToSearchUpperCase) //true
mString.contains(stringToSearchLowerCase) //false
mString.lowercased().contains(stringToSearchUpperCase) //false
mString.lowercased().contains(stringToSearchLowerCase) //true

I don't know why you think there's no constructor. See the API.

Environment.getExternalStorageState() returns path to internal SD mount point like "/mnt/sdcard"

No, Environment.getExternalStorageDirectory() refers to whatever the device manufacturer considered to be "external storage". On some devices, this is removable media, like an SD card. On some devices, this is a portion of on-device flash. Here, "external storage" means "the stuff accessible via USB Mass Storage mode when mounted on a host machine", at least for Android 1.x and 2.x.

But the question is about external SD. How to get a path like "/mnt/sdcard/external_sd" (it may differ from device to device)?

Android has no concept of "external SD", aside from external storage, as described above.

If a device manufacturer has elected to have external storage be on-board flash and also has an SD card, you will need to contact that manufacturer to determine whether or not you can use the SD card (not guaranteed) and what the rules are for using it, such as what path to use for it.

UPDATE

Two recent things of note:

First, on Android 4.4+, you do not have write access to removable media (e.g., "external SD"), except for any locations on that media that might be returned by getExternalFilesDirs() and getExternalCacheDirs(). See Dave Smith's excellent analysis of this, particularly if you want the low-level details.

Second, lest anyone quibble on whether or not removable media access is otherwise part of the Android SDK, here is Dianne Hackborn's assessment:

...keep in mind: until Android 4.4, the official Android platform has not supported SD cards at all except for two special cases: the old school storage layout where external storage is an SD card (which is still supported by the platform today), and a small feature added to Android 3.0 where it would scan additional SD cards and add them to the media provider and give apps read-only access to their files (which is also still supported in the platform today).

Android 4.4 is the first release of the platform that has actually allowed applications to use SD cards for storage. Any access to them prior to that was through private, unsupported APIs. We now have a quite rich API in the platform that allows applications to make use of SD cards in a supported way, in better ways than they have been able to before: they can make free use of their app-specific storage area without requiring any permissions in the app, and can access any other files on the SD card as long as they go through the file picker, again without needing any special permissions.

With \ you escape special characters

Escapes special characters to literal and literal characters to special.

E.g: /\(s\)/ matches '(s)' while /(\s)/ matches any whitespace and captures the match.

Good question. But I think there is no good answer which fits your criteria. The best I can think of is to use an extra vars file.

A task like this:

- include_vars: concat.yml

And in concat.yml you have your definition:

newvar: "{{ var1 }}-{{ var2 }}-{{ var3 }}"

If you need to loop inside a directory recursively for a particular kind of file, use the below command, which filters all the files of doc file type

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc

If you need to do the filteration on multiple types, use the below command.

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc,*.pdf

Now $fileNames variable act as an array from which you can loop and apply your business logic.

You can check GBDeviceInfo on GitHub, also available via CocoaPods. It provides simple API for detecting various properties with support of all latest devices:

• Device family

[GBDeviceInfo deviceDetails].family == GBDeviceFamilyiPhone;

• Device model

[GBDeviceInfo deviceDetails].model == GBDeviceModeliPhone6.

You could just do:

var canvas = yourCanvasElement;
var mouseX = (event.clientX - (canvas.offsetLeft - canvas.scrollLeft)) - 2;
var mouseY = (event.clientY - (canvas.offsetTop - canvas.scrollTop)) - 2;

This will give you the exact position of the mouse pointer.

I'm replacing a submit button with an anchor link. Since calling form.submit() does not activate onsubmit's, I'm finding it, and eval()ing it myself. But I'd like to check if the function exists before just eval()ing what's there. – gms8994

<script type="text/javascript">
function onsubmitHandler() {
    alert('running onsubmit handler');
    return true;
}
function testOnsubmitAndSubmit(f) {
    if (typeof f.onsubmit === 'function') {
        // onsubmit is executable, test the return value
        if (f.onsubmit()) {
            // onsubmit returns true, submit the form
            f.submit();
        }
    }
}
</script>

<form name="theForm" onsubmit="return onsubmitHandler();">
<a href="#" onclick="
    testOnsubmitAndSubmit(document.forms['theForm']);
    return false;
"></a>
</form>

EDIT : missing parameter f in function testOnsubmitAndSubmit

The above should work regardless of whether you assign the onsubmit HTML attribute or assign it in JavaScript:

document.forms['theForm'].onsubmit = onsubmitHandler;

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

apply() was added in 2.3, it commits without returning a boolean indicating success or failure.

commit() returns true if the save works, false otherwise.

apply() was added as the Android dev team noticed that almost no one took notice of the return value, so apply is faster as it is asynchronous.
