How about the Omondo Plugin for Eclipse. I have used it and I find it to be quite useful. Although if you are generating diagrams for large sources, you might have to start Eclipse with more memory.

I came up with 4 methods to achieve the results. Here is demo

Method 1:

#a {
    margin-right: auto;
}

Method 2:

#a {
    flex-grow: 1;
}

Method 3:

#b {
    margin-left: auto;
}

Method 4:

#container {
    justify-content: space-between;
}

On Linux, Unix, Git Bash, or Cygwin, try:

rm -f .git/index.lock

On Windows Command Prompt, try:

del .git\index.lock

For Windows:

• From a PowerShell console opened as administrator, try

  rm -Force ./.git/index.lock
  

• If that does not work, you must kill all git.exe processes

  taskkill /F /IM git.exe
  

  SUCCESS: The process "git.exe" with PID 20448 has been terminated.
  SUCCESS: The process "git.exe" with PID 11312 has been terminated.
  SUCCESS: The process "git.exe" with PID 23868 has been terminated.
  SUCCESS: The process "git.exe" with PID 27496 has been terminated.
  SUCCESS: The process "git.exe" with PID 33480 has been terminated.
  SUCCESS: The process "git.exe" with PID 28036 has been terminated. \

  rm -Force ./.git/index.lock
  

in code add below line:

spin27.setLayoutParams(new LinearLayout.LayoutParams(200, 120));

You need to give the WebClient object the credentials. Something like this...

 WebClient client = new WebClient();
 client.Credentials = new NetworkCredential("username", "password");

The short answer is: No. The only way to post images is through the mobile app.

From the Instagram API documentation: http://instagram.com/developer/endpoints/media/

At this time, uploading via the API is not possible. We made a conscious choice not to add this for the following reasons:

• Instagram is about your life on the go – we hope to encourage photos from within the app. However, in the future we may give whitelist access to individual apps on a case by case basis.
• We want to fight spam & low quality photos. Once we allow uploading from other sources, it's harder to control what comes into the Instagram ecosystem.

All this being said, we're working on ways to ensure users have a consistent and high-quality experience on our platform.

For a nested Json(example below), you can form a query using postman as shown below.

{
    "Items": {
        "sku": "10 Units",
        "Price": "20 Rs"
    },
    "Characteristics": {
        "color": "blue",
        "weight": "2 lb"
    }
}

I don't know why

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%'
    AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')

Here is a slightly different approach to read-only properties, which perhaps should be called write-once properties since they do have to get initialized, don't they? For the paranoid among us who worry about being able to modify properties by accessing the object's dictionary directly, I've introduced "extreme" name mangling:

from uuid import uuid4

class ReadOnlyProperty:
    def __init__(self, name):
        self.name = name
        self.dict_name = uuid4().hex
        self.initialized = False

    def __get__(self, instance, cls):
        if instance is None:
            return self
        else:
            return instance.__dict__[self.dict_name]

    def __set__(self, instance, value):
        if self.initialized:
            raise AttributeError("Attempt to modify read-only property '%s'." % self.name)
        instance.__dict__[self.dict_name] = value
        self.initialized = True

class Point:
    x = ReadOnlyProperty('x')
    y = ReadOnlyProperty('y')
    def __init__(self, x, y):
        self.x = x
        self.y = y

if __name__ == '__main__':
    try:
        p = Point(2, 3)
        print(p.x, p.y)
        p.x = 9
    except Exception as e:
        print(e)

Maven working terminology having phases and goals.

Phase:Maven phase is a set of action which is associated with 2 or 3 goals

exmaple:- if you run mvn clean

this is the phase will execute the goal mvn clean:clean

Goal:Maven goal bounded with the phase

for reference http://books.sonatype.com/mvnref-book/reference/lifecycle-sect-structure.html

If you have control over the structure of the list, the most pythonic thing to do would probably be to change it from:

l=[1,2,3,4]

to:

l=[(1,2),(3,4)]

Then, your loop would be:

for i,j in l:
    print i, j

I encountered the same problem with troubleshooting EXC_BAD_ACCESS and had hard time to find the setting with Xcode 4.2 (the latest one that comes with iOS5 SDK). Apple keeps on moving things and the settings are no longer where they used to be.

Fortunately, I've found it and it works for the device, not just Simulator. You need to open the Product menu in the Xcode, select Edit scheme and then choose the Diagnostics tab. There you have "Enable Zombie Objects". Once selected and run in debugger will point you to the double released object! Enjoy!

In short

Product->Edit Scheme->Diagnostics-> Click Enable Zombie Objects

When you open a file with the name address.csv, you are telling the open() function that your file is in the current working directory. This is called a relative path.

To give you an idea of what that means, add this to your code:

import os

cwd = os.getcwd()  # Get the current working directory (cwd)
files = os.listdir(cwd)  # Get all the files in that directory
print("Files in %r: %s" % (cwd, files))

That will print the current working directory along with all the files in it.

Another way to tell the open() function where your file is located is by using an absolute path, e.g.:

f = open("/Users/foo/address.csv")

I ran into this problem today, and finding no good solutions for it, I created a module to address it. I was inspired by @fbartho's snippet, but wanted to avoid overwriting the fs module.

The module I wrote is Filequeue, and you use it just like fs:

var Filequeue = require('filequeue');
var fq = new Filequeue(200); // max number of files to open at once

fq.readdir('/Users/xaver/Downloads/xaver/xxx/xxx/', function(err, files) {
    if(err) {
        throw err;
    }
    files.forEach(function(file) {
        fq.readFile('/Users/xaver/Downloads/xaver/xxx/xxx/' + file, function(err, data) {
            // do something here
        }
    });
});

Question already answered by the OP, but I am posting this answer for anyone having similar problem, retting to

Could not input open file: composer.phar

error message.

Simply go to your project directory/folder and do a

composer update

Assuming this is where you have your web application:

/Library/WebServer/Documents/zendframework

change directory to it, and then run composer update.

using (var client = new WebClient())
{
    client.DownloadFile("http://example.com/file/song/a.mpeg", "a.mpeg");
}

Gumbo's answer in the Stack Overflow question How to hide the .html extension with Apache mod_rewrite should work fine.

Re 1) Change the .html to .php

Re a.) Yup, that's possible, just add #tab to the URL.

Re b.) That's possible using QSA (Query String Append), see below.

This should also work in a sub-directory path:

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule !.*\.php$ %{REQUEST_FILENAME}.php [QSA,L]

I realize this is a later answer, but I found another reference to a way to address this issue that might help others in the future. This web page describes setting an environment variable (COMPLUS_ZapDisable=1) that prevents optimization, at least it did for me! (Don't forget the second part of disabling the Visual Studio hosting process.) In my case, this might have been even more relevant because I was debugging an external DLL thru a symbol server, but I'm not sure.

Just Like TempTables, a local table variable is also created in TempDB. The scope of table variable is the batch, stored procedure and statement block in which it is declared. They can be passed as parameters between procedures. They are automatically dropped when you close that session on which you create them.

Client side code: I had a requirement where my nodejs webserver should work as both server as well as client, so i added below code when i need it as client, It should work fine, i am using it and working fine for me!!!

const socket = require('socket.io-client')('http://192.168.0.8:5000', {
            reconnection: true,
            reconnectionDelay: 10000
          });
    
        socket.on('connect', (data) => {
            console.log('Connected to Socket');
        });
        
        socket.on('event_name', (data) => {
            console.log("-----------------received event data from the socket io server");
        });
    
        //either 'io server disconnect' or 'io client disconnect'
        socket.on('disconnect', (reason) => {
            console.log("client disconnected");
            if (reason === 'io server disconnect') {
              // the disconnection was initiated by the server, you need to reconnect manually
              console.log("server disconnected the client, trying to reconnect");
              socket.connect();
            }else{
                console.log("trying to reconnect again with server");
            }
            // else the socket will automatically try to reconnect
          });
    
        socket.on('error', (error) => {
            console.log(error);
        });

After installation/upgrading node via brew I ran into this issue exactly: the node command worked but not the npm command.

I used these commands to fix it.

brew uninstall node
brew update
brew upgrade
brew cleanup
brew install node
sudo chown -R $(whoami) /usr/local
brew link --overwrite node
brew postinstall node

I pieced together this solution after trial and error using...

• a github thread: https://github.com/npm/npm/issues/3125

• this site: http://developpeers.com/blogs/fix-for-homebrew-permission-denied-issues

Natural verses artifical keys is a kind of religious debate among the database community - see this article and others it links to. I'm neither in favour of always having artifical keys, nor of never having them. I would decide on a case-by-case basis, for example:

• US States: I'd go for state_code ('TX' for Texas etc.), rather than state_id=1 for Texas
• Employees: I'd usually create an artifical employee_id, because it's hard to find anything else that works. SSN or equivalent may work, but there could be issues like a new joiner who hasn't supplied his/her SSN yet.
• Employee Salary History: (employee_id, start_date). I would not create an artifical employee_salary_history_id. What point would it serve (other than "foolish consistency")

Wherever artificial keys are used, you should always also declare unique constraints on the natural keys. For example, use state_id if you must, but then you'd better declare a unique constraint on state_code, otherwise you are sure to eventually end up with:

state_id    state_code   state_name
137         TX           Texas
...         ...          ...
249         TX           Texas

I just noticed that this question is quite old. Nevertheless, I consider the following aspects to be worth adding:

• Use MongoDB if you don't know yet how you're going to query your data.

  MongoDB is suited for Hackathons, startups or every time you don't know how you'll query the data you inserted. MongoDB does not make any assumptions on your underlying schema. While MongoDB is schemaless and non-relational, this does not mean that there is no schema at all. It simply means that your schema needs to be defined in your app (e.g. using Mongoose). Besides that, MongoDB is great for prototyping or trying things out. Its performance is not that great and can't be compared to Redis.

• Use Redis in order to speed up your existing application.

  Redis can be easily integrated as a LRU cache. It is very uncommon to use Redis as a standalone database system (some people prefer referring to it as a "key-value"-store). Websites like Craigslist use Redis next to their primary database. Antirez (developer of Redis) demonstrated using Lamernews that it is indeed possible to use Redis as a stand alone database system.

• Redis does not make any assumptions based on your data.

  Redis provides a bunch of useful data structures (e.g. Sets, Hashes, Lists), but you have to explicitly define how you want to store you data. To put it in a nutshell, Redis and MongoDB can be used in order to achieve similar things. Redis is simply faster, but not suited for prototyping. That's one use case where you would typically prefer MongoDB. Besides that, Redis is really flexible. The underlying data structures it provides are the building blocks of high-performance DB systems.

When to use Redis?

• Caching

  Caching using MongoDB simply doesn't make a lot of sense. It would be too slow.

• If you have enough time to think about your DB design.

  You can't simply throw in your documents into Redis. You have to think of the way you in which you want to store and organize your data. One example are hashes in Redis. They are quite different from "traditional", nested objects, which means you'll have to rethink the way you store nested documents. One solution would be to store a reference inside the hash to another hash (something like key: [id of second hash]). Another idea would be to store it as JSON, which seems counter-intuitive to most people with a *SQL-background.

• If you need really high performance.

  Beating the performance Redis provides is nearly impossible. Imagine you database being as fast as your cache. That's what it feels like using Redis as a real database.

• If you don't care that much about scaling.

  Scaling Redis is not as hard as it used to be. For instance, you could use a kind of proxy server in order to distribute the data among multiple Redis instances. Master-slave replication is not that complicated, but distributing you keys among multiple Redis-instances needs to be done on the application site (e.g. using a hash-function, Modulo etc.). Scaling MongoDB by comparison is much simpler.

When to use MongoDB

• Prototyping, Startups, Hackathons

  MongoDB is perfectly suited for rapid prototyping. Nevertheless, performance isn't that good. Also keep in mind that you'll most likely have to define some sort of schema in your application.

• When you need to change your schema quickly.

  Because there is no schema! Altering tables in traditional, relational DBMS is painfully expensive and slow. MongoDB solves this problem by not making a lot of assumptions on your underlying data. Nevertheless, it tries to optimize as far as possible without requiring you to define a schema.

TL;DR - Use Redis if performance is important and you are willing to spend time optimizing and organizing your data. - Use MongoDB if you need to build a prototype without worrying too much about your DB.

Number of a columns in the result set you can get with code (as DB is used PostgreSQL):

//load the driver for PostgreSQL
Class.forName("org.postgresql.Driver");

String url = "jdbc:postgresql://localhost/test";
Properties props = new Properties();
props.setProperty("user","mydbuser");
props.setProperty("password","mydbpass");
Connection conn = DriverManager.getConnection(url, props);

//create statement
Statement stat = conn.createStatement();

//obtain a result set
ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE");

//from result set give metadata
ResultSetMetaData rsmd = rs.getMetaData();

//columns count from metadata object
int numOfCols = rsmd.getColumnCount();

But you can get more meta-informations about columns:

for(int i = 1; i <= numOfCols; i++)
{
    System.out.println(rsmd.getColumnName(i));
}

And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.

Since django 1.6 you can use first() method like so:

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

Since no other answer has cited the Java language standard, I have decided to write an answer of my own:

In Java, local variables are not, by default, initialized with a certain value (unlike, for example, the field of classes). From the language specification one (§4.12.5) can read the following:

A local variable (§14.4, §14.14) must be explicitly given a value before it is used, by either initialization (§14.4) or assignment (§15.26), in a way that can be verified using the rules for definite assignment (§16 (Definite Assignment)).

Therefore, since the variables a and b are not initialized :

 for (int l= 0; l<x.length; l++) 
    {
        if (x[l] == 0) 
        a++ ;
        else if (x[l] == 1) 
        b++ ;
    }

the operations a++; and b++; could not produce any meaningful results, anyway. So it is logical for the compiler to notify you about it:

Rand.java:72: variable a might not have been initialized
                a++ ;
                ^
Rand.java:74: variable b might not have been initialized
                b++ ;
                ^

However, one needs to understand that the fact that a++; and b++; could not produce any meaningful results has nothing to do with the reason why the compiler displays an error. But rather because it is explicitly set on the Java language specification that

A local variable (§14.4, §14.14) must be explicitly given a value (...)

To showcase the aforementioned point, let us change a bit your code to:

public static Rand searchCount (int[] x) 
{
    if(x == null || x.length  == 0)
      return null;
    int a ; 
    int b ; 

    ...   

    for (int l= 0; l<x.length; l++) 
    {
        if(l == 0)
           a = l;
        if(l == 1)
           b = l;
    }

    ...   
}

So even though the code above can be formally proven to be valid (i.e., the variables a and b will be always assigned with the value 0 and 1, respectively) it is not the compiler job to try to analyze your application's logic, and neither does the rules of local variable initialization rely on that. The compiler checks if the variables a and b are initialized according to the local variable initialization rules, and reacts accordingly (e.g., displaying a compilation error).

I'm not sure why nobody else has suggested this, but you can write a templated function that returns lambda functions. The following solved my problem, the reason I came to this page:

template <typename DATUM>
std::function<double(DATUM)> makeUnweighted() {
  return [](DATUM datum){return 1.0;};
}

Now whenever I want a function that takes a given type of argument (e.g. std::string), I just say

auto f = makeUnweighted<std::string>()

and now f("any string") returns 1.0.

That's an example of what I mean by "templated lambda function." (This particular case is used to automatically provide an inert weighting function when somebody doesn't want to weight their data, whatever their data might be.)

Your web server isn't running! You need to find the XAMPP control panel and start the web server up.

Of course, you might find other problems after that, but this is the first step.

There's no such keyword in C++. List of C++ keywords can be found in section 2.11/1 of C++ language standard. restrict is a keyword in C99 version of C language and not in C++.

Assuming we imported pandas as pd and df is our dataframe

pd.to_datetime(df['date'], unit='s')

works for me.

What @VonC has suggested is nice but I prefer doing all cron job configuration in one line. This would avoid cross platform issues like cronjob location and you don't need a separate cron file.

FROM ubuntu:latest

# Install cron
RUN apt-get -y install cron

# Create the log file to be able to run tail
RUN touch /var/log/cron.log

# Setup cron job
RUN (crontab -l ; echo "* * * * * echo "Hello world" >> /var/log/cron.log") | crontab

# Run the command on container startup
CMD cron && tail -f /var/log/cron.log

After running your docker container, you can make sure if cron service is working by:

# To check if the job is scheduled
docker exec -ti <your-container-id> bash -c "crontab -l"
# To check if the cron service is running
docker exec -ti <your-container-id> bash -c "pgrep cron"

If you prefer to have ENTRYPOINT instead of CMD, then you can substitute the CMD above with

ENTRYPOINT cron start && tail -f /var/log/cron.log

William Jockusch's answer solve this problem with easy trick.

-(void) viewWillDisappear:(BOOL)animated {
    if ([self.navigationController.viewControllers indexOfObject:self]==NSNotFound) {
       // back button was pressed.  We know this is true because self is no longer
       // in the navigation stack.  
    }
    [super viewWillDisappear:animated];
}

When you just want to execute one or several HTTP requests without having to wait for the response, there is a simple PHP solution, as well.

In the calling script:

$socketcon = fsockopen($host, 80, $errno, $errstr, 10);
if($socketcon) {   
   $socketdata = "GET $remote_house/script.php?parameters=... HTTP 1.1\r\nHost: $host\r\nConnection: Close\r\n\r\n";      
   fwrite($socketcon, $socketdata); 
   fclose($socketcon);
}
// repeat this with different parameters as often as you like

On the called script.php, you can invoke these PHP functions in the first lines:

ignore_user_abort(true);
set_time_limit(0);

This causes the script to continue running without time limit when the HTTP connection is closed.

To clarify there is no such thing as a mutable string in C# (or .NET in general). Other langues support mutable strings (string which can change) but the .NET framework does not.

So the correct answer to your question is ALL string are immutable in C#.

string has a specific meaning. "string" lowercase keyword is merely a shortcut for an object instantiated from System.String class. All objects created from string class are ALWAYS immutable.

If you want a mutable representation of text then you need to use another class like StringBuilder. StringBuilder allows you to iteratively build a collection of 'words' and then convert that to a string (once again immutable).

System.out.println("First Name: " + firstname);
System.out.println("Last Name: " + lastname);

or

System.out.println(String.format("First Name: %s", firstname));
System.out.println(String.format("Last Name: %s", lastname));

=COUNTIFS(1:1,FALSE)=0

This will return TRUE or FALSE (Looks for FALSE, if count isn't 0 (all True) it will be false

The logic is simple. setOnClickListener belongs to step 2.

1. You create the button
2. You create an instance of OnClickListener* like it's done in that example and override the onClick-method.
3. You assign that OnClickListener to that button using btn.setOnClickListener(myOnClickListener); in your fragments/activities onCreate-method.
4. When the user clicks the button, the onClick function of the assigned OnClickListener is called.

*If you import android.view.View; you use View.OnClickListener. If you import android.view.View.*; or import android.view.View.OnClickListener; you use OnClickListener as far as I get it.

Another way is to let you activity/fragment inherit from OnClickListener. This way you assign your fragment/activity as the listener for your button and implement onClick as a member-function.

Although other answers include some of the following information, this is the absolute minimum that needs to be changed on EC2 instances, specifically regarding deployment of large WAR files, and is the least likely to cause issues during future updates. I've been running into these limits about every other year due to the ever-increasing size of the Jenkins WAR file (now ~72MB).

More specifically, this answer is applicable if you encounter a variant of the following error in catalina.out:

SEVERE [https-jsse-nio-8443-exec-17] org.apache.catalina.core.ApplicationContext.log HTMLManager:
FAIL - Deploy Upload Failed, Exception:
[org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException:
the request was rejected because its size (75333656) exceeds the configured maximum (52428800)]

On Amazon EC2 Linux instances, the only file that needs to be modified from the default installation of Tomcat (sudo yum install tomcat8) is:

/usr/share/tomcat8/webapps/manager/WEB-INF/web.xml

By default, the maximum upload size is exactly 50MB:

<multipart-config>
  <!-- 50MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

There are only two values that need to be modified (max-file-size and max-request-size):

<multipart-config>
  <!-- 100MB max -->
  <max-file-size>104857600</max-file-size>
  <max-request-size>104857600</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

When Tomcat is upgraded on these instances, the new version of the manager web.xml will be placed in web.xml.rpmnew, so any modifications to the original file will not be overwritten during future updates.

For intel drivers, there is also this method

Disable Vertical Synchronization (VSYNC)

The intel-driver uses Triple Buffering for vertical synchronization, this allows for full performance and avoids tearing. To turn vertical synchronization off (e.g. for benchmarking) use this .drirc in your home directory:

<device screen="0" driver="dri2">
    <application name="Default">
        <option name="vblank_mode" value="0"/>
    </application>

Never hardcode sensitive information (account credentials, passwords, etc.). Instead, create a file to store that information as environment variables (key/value pairs), and exclude that file from your source code management system. For example, in terms of Git (source code management system), exclude that file by adding it to .gitignore:

-bash> echo '/config/app_environment_variables.rb' >> .gitignore 

/config/app_environment_variables.rb

ENV['HTTP_USER'] = 'devuser'
ENV['HTTP_PASS'] = 'devpass'

As well, add the following lines to /config/environment.rb, between the require line, and the Application.initialize line:

# Load the app's custom environment variables here, so that they are loaded before environments/*.rb
app_environment_variables = File.join(Rails.root, 'config', 'app_environment_variables.rb')
load(app_environment_variables) if File.exists?(app_environment_variables)

That's it!

As the comment above says, by doing this you will be loading your environment variables before environments/*.rb, which means that you will be able to refer to your variables inside those files (e.g. environments/production.rb). This is a great advantage over putting your environment variables file inside /config/initializers/.

Inside app_environment_variables.rb there's no need to distinguish environments as far as development or production because you will never commit this file into your source code management system, hence it is for the development context by default. But if you need to set something special for the test environment (or for occasions when you test production mode locally), just add a conditional block below all the other variables:

if Rails.env.test?
  ENV['HTTP_USER'] = 'testuser'
  ENV['HTTP_PASS'] = 'testpass'
end

if Rails.env.production?
  ENV['HTTP_USER'] = 'produser'
  ENV['HTTP_PASS'] = 'prodpass'
end

Whenever you update app_environment_variables.rb, restart the app server. Assuming you are using the likes of Apache/Passenger or rails server:

-bash> touch tmp/restart.txt

In your code, refer to the environment variables as follows:

def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    username == ENV['HTTP_USER'] && password == ENV['HTTP_PASS']
  end
end

Note that inside app_environment_variables.rb you must specify booleans and numbers as strings (e.g. ENV['SEND_MAIL'] = 'false' not just false, and ENV['TIMEOUT'] = '30' not just 30), otherwise you will get the errors can't convert false into String and can't convert Fixnum into String, respectively.

Storing and sharing sensitive information

The final knot to tie is: how to share this sensitive information with your clients and/or partners? For the purpose of business continuity (i.e. when you get hit by a falling star, how will your clients and/or partners resume full operations of the site?), your clients and/or partners need to know all the credentials required by your app. Emailing/Skyping these things around is insecure and leads to disarray. Storing it in shared Google Docs is not bad (if everyone uses https), but an app dedicated to storing and sharing small titbits like passwords would be ideal.

How to set environment variables on Heroku

If you have a single environment on Heroku:

-bash> heroku config:add HTTP_USER='herouser'
-bash> heroku config:add HTTP_USER='heropass'

If you have multiple environments on Heroku:

-bash> heroku config:add HTTP_USER='staguser' --remote staging
-bash> heroku config:add HTTP_PASS='stagpass' --remote staging

-bash> heroku config:add HTTP_USER='produser' --remote production
-bash> heroku config:add HTTP_PASS='prodpass' --remote production

Foreman and .env

Many developers use Foreman (installed with the Heroku Toolbelt) to run their apps locally (as opposed to using the likes of Apache/Passenger or rails server). Foreman and Heroku use Procfile for declaring what commands are run by your application, so the transition from local dev to Heroku is seamless in that regard. I use Foreman and Heroku in every Rails project, so this convenience is great. But here's the thing.. Foreman loads environment variables stored in /.env via dotenv but unfortunately dotenv essentially only parses the file for key=value pairs; those pairs don't become variables right there and then, so you can't refer to already set variables (to keep things DRY), nor can you do "Ruby" in there (as noted above with the conditionals), which you can do in /config/app_environment_variables.rb. For instance, in terms of keeping things DRY I sometimes do stuff like this:

ENV['SUPPORT_EMAIL']='Company Support <[email protected]>'
ENV['MAILER_DEFAULT_FROM'] = ENV['SUPPORT_EMAIL']
ENV['MAILER_DEFAULT_TO']   = ENV['SUPPORT_EMAIL']

Hence, I use Foreman to run my apps locally, but I don't use its .env file for loading environment variables; rather I use Foreman in conjunction with the /config/app_environment_variables.rb approach described above.

ulimit -s unlimited lets the stack grow unlimited.

This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.

If you only need filenames and since I didn't really like most of the solutions here (feature-wise or readability-wise), how about this lazy one?

private void Foo()
{
  var files = GetAllFiles("pathToADirectory");
  foreach (string file in files)
  {
      // Use can use Path.GetFileName() or similar to extract just the filename if needed
      // You can break early and it won't still browse your whole disk since it's a lazy one
  }
}

Change your div into a flex container:

div { display:flex; }

Now there are two methods to center the alignments for all the content:

Method 1:

div { align-items:center; }

DEMO

Method 2:

div * { margin-top:auto; margin-bottom:auto; }

DEMO

Try different width and height values on the img and different font size values on the span and you'll see they always remain in the middle of the container.

Not complicated.

<div ng-app="Application" ng-controller="TreeController">
    <table>
        <thead>
            <tr>
                <th>col 1</th>
                <th>col 2</th>
                <th>col 3</th>
            </tr>
        </thead>
        <tbody ng-repeat="item in tree">
            <tr>
                <td>{{item.id}}</td>
                <td>{{item.fname}}</td>
                <td>{{item.lname}}</td>
            </tr>
            <tr ng-repeat="children in item.child">
                <td style="padding-left:15px;">{{children.id}}</td>
                <td>{{children.fname}}</td>
            </tr>
        </tbody>
     </table>
</div>

controller code:

angular.module("myApp", []).
controller("TreeController", ['$scope', function ($scope) {
    $scope.tree = [{
        id: 1,
        fname: "tree",
        child: [{
            id: 1,
            fname: "example"
        }],
        lname: "grid"
    }];


}]);

If anybody still looking at this question, the currently accepted answer is now outdated:

Since Python 3.7* the dictionaries are order-preserving, that is they now behave exactly as collections.OrderedDicts used to. Unfortunately, there is still no dedicated method to index into keys() / values() of the dictionary, so getting the first key / value in the dictionary can be done as

first_key = list(colors)[0]
first_val = list(colors.values())[0]

or alternatively (this avoids instantiating the keys view into a list):

def get_first_key(dictionary):
    for key in dictionary:
        return key
    raise IndexError

first_key = get_first_key(colors)
first_val = colors[first_key]

If you need an n-th key, then similarly

def get_nth_key(dictionary, n=0):
    if n < 0:
        n += len(dictionary)
    for i, key in enumerate(dictionary.keys()):
        if i == n:
            return key
    raise IndexError("dictionary index out of range") 

(*CPython 3.6 already included ordered dicts, but this was only an implementation detail. The language specification includes ordered dicts from 3.7 onwards.)

You just have to set UIFileSharingEnabled (Application Supports iTunes file sharing) key in the info plist of your app. Here's a link for the documentation. Scroll down to the file sharing support part.

In the past, it was also necessary to define CFBundleDisplayName (Bundle Display Name), if it wasn't already there. More details here.

you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

I believe the responses already posted should get people going in the right direction. However here is what I did that made sense for the legacy code I was updating. The legacy code was using the URI from the gallery to change and then save the images.

Prior to 4.4 (and google drive), the URIs would look like this: content://media/external/images/media/41

As stated in the question, they more often look like this: content://com.android.providers.media.documents/document/image:3951

Since I needed the ability to save images and not disturb the already existing code, I just copied the URI from the gallery into the data folder of the app. Then originated a new URI from the saved image file in the data folder.

Here's the idea:

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent), CHOOSE_IMAGE_REQUEST);

public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);

    File tempFile = new File(this.getFilesDir().getAbsolutePath(), "temp_image");

    //Copy URI contents into temporary file.
    try {
        tempFile.createNewFile();
        copyAndClose(this.getContentResolver().openInputStream(data.getData()),new FileOutputStream(tempFile));
    }
    catch (IOException e) {
        //Log Error
    }

    //Now fetch the new URI
    Uri newUri = Uri.fromFile(tempFile);

    /* Use new URI object just like you used to */
 }

Note - copyAndClose() just does file I/O to copy InputStream into a FileOutputStream. The code is not posted.

Add binding property selected, but make sure to make it null, for other fields e.g:

<option *ngFor="#workout of workouts" [selected]="workout.name =='back' ? true: null">{{workout.name}}</option>

Now it will work

You can use CSS grid to achieve this, this is the long-hand version for the purposes of illustration:

div.container {_x000D_
    display: grid;_x000D_
    grid-template-columns: 220px 20px auto;_x000D_
    grid-template-rows: auto;_x000D_
}_x000D_
_x000D_
div.left {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 2;_x000D_
    grid-row-start: row1-start_x000D_
    grid-row-end: 3;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    grid-column-start: 3;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 1;_x000D_
    grid-row-end; 1;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.below {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 2;_x000D_
    grid-row-end; 2;_x000D_
}

<div class="container">_x000D_
    <div class="left">Left</div>_x000D_
    <div class="right">Right</div>_x000D_
    <div class="below">Below</div>_x000D_
</div>

Or the more traditional method using float and margin.

I have included a background colour in this example to help show where things are - and also what to do with content below the floated-area.

Don't put your styles inline in real life, extract them into a style sheet.

div.left {_x000D_
    width: 200px;_x000D_
    float: left;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    margin-left: 220px;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.clear {_x000D_
    clear: both;_x000D_
}

    <div class="left"> Left </div>_x000D_
    <div class="right"> Right </div>_x000D_
    <div class="clear">Below</div>

<div style="width: 200px; float: left; background-color: Aqua;"> Left </div>
<div style="margin-left: 220px; background-color: Silver;"> Right </div>
<div style="clear: both;">Below</div>

I solved this with some lines of code, opening the file, going trough it and adding indentation, then saving it again. I was working with small xml files, and did not want to add dependencies, or more libraries to install for the user. Anyway, here is what I ended up with:

    f = open(file_name,'r')
    xml = f.read()
    f.close()

    #Removing old indendations
    raw_xml = ''        
    for line in xml:
        raw_xml += line

    xml = raw_xml

    new_xml = ''
    indent = '    '
    deepness = 0

    for i in range((len(xml))):

        new_xml += xml[i]   
        if(i<len(xml)-3):

            simpleSplit = xml[i:(i+2)] == '><'
            advancSplit = xml[i:(i+3)] == '></'        
            end = xml[i:(i+2)] == '/>'    
            start = xml[i] == '<'

            if(advancSplit):
                deepness += -1
                new_xml += '\n' + indent*deepness
                simpleSplit = False
                deepness += -1
            if(simpleSplit):
                new_xml += '\n' + indent*deepness
            if(start):
                deepness += 1
            if(end):
                deepness += -1

    f = open(file_name,'w')
    f.write(new_xml)
    f.close()

It works for me, perhaps someone will have some use of it :)

I think the query you want is this:

SELECT BrandId, SUM(ICount),
       SUM(sum(ICount)) over () as TotalCount,
       100.0 * SUM(ICount) / SUM(sum(Icount)) over () as Percentage
FROM Table 
WHERE DateId  = 20130618
group by BrandId;

This does the group by for brand. And it calculates the "Percentage". This version should produce a number between 0 and 100.

The function declaration int writeFile () ; seems to be missing in the code. Add int writeFile () ; before the function main()

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

possible just do:

static const std::string RECTANGLE() const {
    return "rectangle";
} 

or

#define RECTANGLE "rectangle"

os.path.abspath doesn't validate anything, so if we're already appending strings to __file__ there's no need to bother with dirname or joining or any of that. Just treat __file__ as a directory and start climbing:

# climb to __file__'s parent's parent:
os.path.abspath(__file__ + "/../../")

That's far less convoluted than os.path.abspath(os.path.join(os.path.dirname(__file__),"..")) and about as manageable as dirname(dirname(__file__)). Climbing more than two levels starts to get ridiculous.

But, since we know how many levels to climb, we could clean this up with a simple little function:

uppath = lambda _path, n: os.sep.join(_path.split(os.sep)[:-n])

# __file__ = "/aParent/templates/blog1/page.html"
>>> uppath(__file__, 1)
'/aParent/templates/blog1'
>>> uppath(__file__, 2)
'/aParent/templates'
>>> uppath(__file__, 3)
'/aParent'

You can't detect the codepage

This is clearly false. Every web browser has some kind of universal charset detector to deal with pages which have no indication whatsoever of an encoding. Firefox has one. You can download the code and see how it does it. See some documentation here. Basically, it is a heuristic, but one that works really well.

Given a reasonable amount of text, it is even possible to detect the language.

Here's another one I just found using Google:

One way would be to convert both strings to upper or lower:

test $(echo "string" | /bin/tr '[:upper:]' '[:lower:]') = $(echo "String" | /bin/tr '[:upper:]' '[:lower:]') && echo same || echo different

Another way would be to use grep:

echo "string" | grep -qi '^String$' && echo same || echo different

You might also, like me, have installed php-cgi prior to installing Apache and when doing so it doesn't set up Apache properly to run PHP, removing PHP entirely and reinstalling seemed to fix my problem.

IndexError: invalid index to scalar variable happens when you try to index a numpy scalar such as numpy.int64 or numpy.float64. It is very similar to TypeError: 'int' object has no attribute '__getitem__' when you try to index an int.

>>> a = np.int64(5)
>>> type(a)
<type 'numpy.int64'>
>>> a[3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: invalid index to scalar variable.
>>> a = 5
>>> type(a)
<type 'int'>
>>> a[3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Check that you are building a 64-bit process, and not a 32-bit one, which is the default compilation mode of Visual Studio. To do this, right click on your project, Properties -> Build -> platform target : x64. As any 32-bit process, Visual Studio applications compiled in 32-bit have a virtual memory limit of 2GB.

64-bit processes do not have this limitation, as they use 64-bit pointers, so their theoretical maximum address space (the size of their virtual memory) is 16 exabytes (2^64). In reality, Windows x64 limits the virtual memory of processes to 8TB. The solution to the memory limit problem is then to compile in 64-bit.

However, object’s size in Visual Studio is still limited to 2GB, by default. You will be able to create several arrays whose combined size will be greater than 2GB, but you cannot by default create arrays bigger than 2GB. Hopefully, if you still want to create arrays bigger than 2GB, you can do it by adding the following code to you app.config file:

<configuration>
  <runtime>
    <gcAllowVeryLargeObjects enabled="true" />
  </runtime>
</configuration>

From Save MySQL query results into a text or CSV file:

MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other application which accepts data in CSV format.

Given a query such as

SELECT order_id,product_name,qty FROM orders

which returns three columns of data, the results can be placed into the file /tmp/orders.txt using the query:

SELECT order_id,product_name,qty FROM orders
INTO OUTFILE '/tmp/orders.txt'

This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:

SELECT order_id,product_name,qty FROM orders
INTO OUTFILE '/tmp/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'

In this example, each field will be enclosed in double quotes, the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:

"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95"

Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.

Syntax

   SELECT Your_Column_Name
    FROM Your_Table_Name
    INTO OUTFILE 'Filename.csv'
    FIELDS TERMINATED BY ','
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

Or you could try to grab the output via the client:

You could try executing the query from the your local client and redirect the output to a local file destination:

mysql -user -pass -e "select cols from table where cols not null" > /tmp/output

Hint: If you don't specify an absoulte path but use something like INTO OUTFILE 'output.csv' or INTO OUTFILE './output.csv', it will store the output file to the directory specified by show variables like 'datadir';.

What about including the current directory in the search path?

ruby -I. main.rb

Unless you can get PHP to label that element with a class you are better to use jQuery.

jQuery(document).ready(function () {
  $count =  jQuery("ul li").size() - 1;
  alert($count);
  jQuery("ul li:nth-child("+$count+")").css("color","red");
});

I had terrible trouble with the both the PEAR-based and the simpler alternatives shown. So here's a solution that leverages the Unix diff command (obviously, you have to be on a Unix system or have a working Windows diff command for it to work). Choose your favourite temporary directory, and change the exceptions to return codes if you prefer.

 * @param $new string The new string
 * @param $old string The old string
 * @return string Human-readable output as produced by the Unix diff command,
 * or "No changes" if the strings are the same.
 * @throws Exception
 */
public static function diff($new, $old) {
  $tempdir = '/var/somewhere/tmp'; // Your favourite temporary directory
  $oldfile = tempnam($tempdir,'OLD');
  $newfile = tempnam($tempdir,'NEW');
  if (!@file_put_contents($oldfile,$old)) {
    throw new Exception('diff failed to write temporary file: ' . 
         print_r(error_get_last(),true));
  }
  if (!@file_put_contents($newfile,$new)) {
    throw new Exception('diff failed to write temporary file: ' . 
         print_r(error_get_last(),true));
  }
  $answer = array();
  $cmd = "diff $newfile $oldfile";
  exec($cmd, $answer, $retcode);
  unlink($newfile);
  unlink($oldfile);
  if ($retcode != 1) {
    throw new Exception('diff failed with return code ' . $retcode);
  }
  if (empty($answer)) {
    return 'No changes';
  } else {
    return implode("\n", $answer);
  }
}

Make sure you are using binding to get component props in REACT

class FileUploader extends Component {
  constructor (props) {
    super(props);
    this.handleClick = this.handleClick.bind(this);

   onChange=(e,props)=>{
    const files = e.target.files;
    const selectedFile = files[0];
    ProcessFileUpload(selectedFile,props.ProgressCallBack,props.ErrorCallBack,props.CompleatedCallBack,props.BaseURL,props.Location,props.FilesAllowed);
  }
   handleClick = () => {
    this.refs.fileUploader.click();
  }
  render()
  {
  return(
      <div>
        <button type="button" onClick={this.handleClick}>Select File</button>  
        <input type='file' onChange={(e)=>this.onChange(e,this.props)} ref="fileUploader" style={{display:"none"}} />

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

If you want to take the formatted value of input do this :

$("input").datepicker({ dateFormat: 'dd, mm, yy' });

later in your code when the date is set you could get it by

dateVariable = $("input").val();

If you want just to take a formatted value with datepicker you might want to use the utility

dateString = $.datepicker.formatDate('dd, MM, yy', new Date("20 April 2012"));

I've updated the jsfiddle for experimenting with this

There are some guys at Mozilla working on implementing a PDF reader using HTML5 and JavaScript. It is called pdf.js and one of the developers just made an interesting blog post about the project.

Regarding os.linesep:

Here is an exact unedited Python 2.7.1 interpreter session on Windows:

Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.linesep
'\r\n'
>>> f = open('myfile','w')
>>> f.write('hi there\n')
>>> f.write('hi there' + os.linesep) # same result as previous line ?????????
>>> f.close()
>>> open('myfile', 'rb').read()
'hi there\r\nhi there\r\r\n'
>>>

On Windows:

As expected, os.linesep does NOT produce the same outcome as '\n'. There is no way that it could produce the same outcome. 'hi there' + os.linesep is equivalent to 'hi there\r\n', which is NOT equivalent to 'hi there\n'.

It's this simple: use \n which will be translated automatically to os.linesep. And it's been that simple ever since the first port of Python to Windows.

There is no point in using os.linesep on non-Windows systems, and it produces wrong results on Windows.

DO NOT USE os.linesep!

I resolved this error, I was adding permissions inside Application tag by mistake. I putted outside and it works fine. Hope it helps for someone.

items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:

you can also get the line if there are other characters before token

items=re.findall("^.*token.*$",s,re.MULTILINE)

The above works like grep token on unix and keyword 'in' or .contains in python and C#

Using just File.Create will leave the file open, which probably isn't what you want.

You could use:

using (File.Create(filename)) ;

That looks slightly odd, mind you. You could use braces instead:

using (File.Create(filename)) {}

Or just call Dispose directly:

File.Create(filename).Dispose();

Either way, if you're going to use this in more than one place you should probably consider wrapping it in a helper method, e.g.

public static void CreateEmptyFile(string filename)
{
    File.Create(filename).Dispose();
}

Note that calling Dispose directly instead of using a using statement doesn't really make much difference here as far as I can tell - the only way it could make a difference is if the thread were aborted between the call to File.Create and the call to Dispose. If that race condition exists, I suspect it would also exist in the using version, if the thread were aborted at the very end of the File.Create method, just before the value was returned...

Use the following function to get exact information. It is generated by taking the base of the ATM_CashWithdrawl concept.

I have just modified the code of facebookarchive-StringUtils to get the below format. The same format you will get when you use apache.hadoop-StringUtils

public static String getMemoryUnit(long bytes) {
    DecimalFormat oneDecimal = new DecimalFormat("0.0");
    float BYTE = 1024.0f, KB = BYTE, MB = KB * KB, GB = MB * KB, TB = GB * KB;
    long absNumber = Math.abs(bytes);
    double result = bytes;
    String suffix = " Bytes";
    if (absNumber < MB) {
        result = bytes / KB;
        suffix = " KB";
    } else if (absNumber < GB) {
        result = bytes / MB;
        suffix = " MB";
    } else if (absNumber < TB) {
        result = bytes / GB;
        suffix = " GB";
    }
    return oneDecimal.format(result) + suffix;
}

Example usage of the above methods:

public static void main(String[] args) {
    Runtime runtime = Runtime.getRuntime();
    int availableProcessors = runtime.availableProcessors();

    long heapSize = Runtime.getRuntime().totalMemory();
    long heapMaxSize = Runtime.getRuntime().maxMemory();
    long heapFreeSize = Runtime.getRuntime().freeMemory();

    System.out.format("Total: [%s], Max: [%s], Free: [%s]\n", heapSize, heapMaxSize, heapFreeSize);
    System.out.format("getMemoryUnit(): Total: [%s], Max: [%s], Free: [%s]\n",
            getMemoryUnit(heapSize), getMemoryUnit(heapMaxSize), getMemoryUnit(heapFreeSize));
    System.out.format("getFullMemoryUnit(): Total: [%s], Max: [%s], Free: [%s]\n",
            getFullMemoryUnit(heapSize), getFullMemoryUnit(heapMaxSize), getFullMemoryUnit(heapFreeSize));

Some modern browsers have support for parsing JSON into a native object:

var var1 = '{"cols": [{"i" ....... 66}]}';
var result = JSON.parse(var1);

For the browsers that don't support it, you can download json2.js from json.org for safe parsing of a JSON object. The script will check for native JSON support and if it doesn't exist, provide the JSON global object instead. If the faster, native object is available it will just exit the script leaving it intact. You must, however, provide valid JSON or it will throw an error — you can check the validity of your JSON with http://jslint.com or http://jsonlint.com.

Try the following code to verify whether the file exist. You can create a user function and use it in your stored procedure. modify it as you need:

Set NOCOUNT ON

 DECLARE @Filename NVARCHAR(50)
 DECLARE @fileFullPath NVARCHAR(100)

 SELECT @Filename = N'LogiSetup.log'
 SELECT @fileFullPath = N'C:\LogiSetup.log'

create table #dir

(output varchar(2000))

 DECLARE @cmd NVARCHAR(100)
SELECT @cmd = 'dir ' + @fileFullPath     

insert into #dir    

exec master.dbo.xp_cmdshell @cmd

--Select * from #dir

-- This is risky, as the fle path itself might contain the filename
if exists (Select * from #dir where output like '%'+ @Filename +'%')

       begin    
              Print 'File found'    
              --Add code you want to run if file exists    
       end    
else    
       begin    
              Print 'No File Found'    
              --Add code you want to run if file does not exists    
       end

drop table #dir

Update: I completely rewrote this answer. The old code is still there, at the bottom, but I don't recommend it.

There are two main ways you can get access GET variables:

1. Via PHP's $_GET array (associative array).
2. Via JavaScript's location object.

With PHP, you can just make a "template", which goes something like this:

<script type="text/javascript">
var $_GET = JSON.parse("<?php echo json_encode($_GET); ?>");
</script>

However, I think the mixture of languages here is sloppy, and should be avoided where possible. I can't really think of any good reasons to mix data between PHP and JavaScript anyway.

It really boils down to this:

• If the data can be obtained via JavaScript, use JavaScript.
• If the data can't be obtained via JavaScript, use AJAX.
• If you otherwise need to communicate with the server, use AJAX.

Since we're talking about $_GET here (or at least I assumed we were when I wrote the original answer), you should get it via JavaScript.

In the original answer, I had two methods for getting the query string, but it was too messy and error-prone. Those are now at the bottom of this answer.

Anyways, I designed a nice little "class" for getting the query string (actually an object constructor, see the relevant section from MDN's OOP article):

function QuerystringTable(_url){
    // private
    var url   = _url,
        table = {};

    function buildTable(){
        getQuerystring().split('&').filter(validatePair).map(parsePair);
    }

    function parsePair(pair){
        var splitPair = pair.split('='),
            key       = decodeURIComponent(splitPair[0]),
            value     = decodeURIComponent(splitPair[1]);

        table[key] = value;
    }

    function validatePair(pair){
        var splitPair = pair.split('=');

        return !!splitPair[0] && !!splitPair[1];
    }

    function validateUrl(){
        if(typeof url !== "string"){
            throw "QuerystringTable() :: <string url>: expected string, got " + typeof url;
        }

        if(url == ""){
            throw "QuerystringTable() :: Empty string given for argument <string url>";
        }
    }

    // public
    function getKeys(){
        return Object.keys(table);
    }

    function getQuerystring(){
        var string;

        validateUrl();
        string = url.split('?')[1];

        if(!string){
            string = url;
        }

        return string;
    }

    function getValue(key){
        var match = table[key] || null;

        if(!match){
            return "undefined";
        }

        return match;
    }

    buildTable();
    this.getKeys        = getKeys;
    this.getQuerystring = getQuerystring;
    this.getValue       = getValue;
}

It's much more robust, doesn't rely on regex, combines the best parts of both the previous approaches, and will validate your input. You can give it query strings other than the one from the url, and it will fail loudly if you give bad input. Moreover, like a good object/module, it doesn't know or care about anything outside of the class definition, so it can be used with anything.

The constructor automatically populates its internal table and decodes each string such that ...?foo%3F=bar%20baz&ampersand=this%20thing%3A%20%26, for example, will internally become:

{
    "foo?"      : "bar baz",
    "ampersand" : "this thing: &"
}

All the work is done for you at instantiation.

Here's how to use it:

var qst = new QuerystringTable(location.href);
qst.getKeys()        // returns an array of keys
qst.getValue("foo")  // returns the value of foo, or "undefined" if none.
qst.getQuerystring() // returns the querystring

That's much better. And leaving the url part up to the programmer both allows this to be used in non-browser environments (tested in both node.js and a browser), and allows for a scenario where you might want to compare two different query strings.

var qs1 = new QuerystringTable(/* url #1 */),
    qs2 = new QuerystringTable(/* url #2 */);

if (qs1.getValue("vid") !== qs2.getValue("vid")){
    // Do something
}

As I said above, there were two messy methods that are referenced by this answer. I'm keeping them here so readers don't have to hunt through revision history to find them. Here they are:

1) Direct parse by function. This just grabs the url and parses it directly with RegEx

$_GET=function(key,def){
    try{
        return RegExp('[?&;]'+key+'=([^?&#;]*)').exec(location.href)[1]
    }catch(e){
        return def||''
    }
}

Easy peasy, if the query string is ?ducksays=quack&bearsays=growl, then $_GET('ducksays') should return quack and $_GET('bearsays') should return growl

Now you probably instantly notice that the syntax is different as a result of being a function. Instead of $_GET[key], it is $_GET(key). Well, I thought of that :)

Here comes the second method:

---

2) Object Build by Loop

onload=function(){
    $_GET={}//the lack of 'var' makes this global
    str=location.search.split('&')//not '?', this will be dealt with later
    for(i in str){
        REG=RegExp('([^?&#;]*)=([^?&#;]*)').exec(str[i])
        $_GET[REG[1]]=REG[2]
    }
}

Behold! $_GET is now an object containing an index of every object in the url, so now this is possible:

$_GET['ducksays']//returns 'quack'

AND this is possible

for(i in $_GET){
    document.write(i+': '+$_GET[i]+'<hr>')
}

This is definitely not possible with the function.

Again, I don't recommend this old code. It's badly written.

If (condition, condition_is_true, condition_is_false)

It will look like this in longer version:

If (condition_is_true) Then 

Else (condition_is_false)

End If

In order to add an EventListener to an element in angular 2+, we can use the method listen of the Renderer2 service (Renderer is deprecated, so use Renderer2):

listen(target: 'window'|'document'|'body'|any, eventName: string, callback: (event: any) => boolean | void): () => void

Example:

export class ListenDemo implements AfterViewInit { 
   @ViewChild('testElement') 
   private testElement: ElementRef;
   globalInstance: any;       

   constructor(private renderer: Renderer2) {
   }

   ngAfterViewInit() {
       this.globalInstance = this.renderer.listen(this.testElement.nativeElement, 'click', () => {
           this.renderer.setStyle(this.testElement.nativeElement, 'color', 'green');
       });
    }
}

Note:

When you use this method to add an event listener to an element in the dom, you should remove this event listener when the component is destroyed

You can do that this way:

ngOnDestroy() {
  this.globalInstance();
}

The way of use of ElementRef in this method should not expose your angular application to a security risk. for more on this referrer to ElementRef security risk angular 2

$date1 = date_create("2017-04-15");
$date2 = date_create("2017-05-18");

//difference between two dates
$diff = date_diff($date1,$date2);

//count days
echo 'Days Count - '.$diff->format("%a");

For another approach, you can wrap your tests in a function and use normal conditional checks at runtime to only execute them if you want.

#include <gtest/gtest.h>

const bool skip_some_test = true;

bool some_test_was_run = false;

void someTest() {
   EXPECT_TRUE(!skip_some_test);
   some_test_was_run = true;
}

TEST(BasicTest, Sanity) {
   EXPECT_EQ(1, 1);
   if(!skip_some_test) {
      someTest();
      EXPECT_TRUE(some_test_was_run);

This is useful for me as I'm trying to run some tests only when a system supports dual stack IPv6.

Technically that dualstack stuff shouldn't really be a unit test as it depends on the system. But I can't really make any integration tests until I have tested they work anyway and this ensures that it won't report failures when it's not the codes fault.

As for the test of it I have stub objects that simulate a system's support for dualstack (or lack of) by constructing fake sockets.

The only downside is that the test output and the number of tests will change which could cause issues with something that monitors the number of successful tests.

You can also use ASSERT_* rather than EQUAL_*. Assert will about the rest of the test if it fails. Prevents a lot of redundant stuff being dumped to the console.

var myString = "something format_abc";_x000D_
var arr = myString.match(/\bformat_(.*?)\b/);_x000D_
console.log(arr[0] + " " + arr[1]);

The \b isn't exactly the same thing. (It works on --format_foo/, but doesn't work on format_a_b) But I wanted to show an alternative to your expression, which is fine. Of course, the match call is the important thing.

Your project is too large. You have too many methods. There can only be 65536 methods per application. see here https://code.google.com/p/android/issues/detail?id=7147#c6

I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.

The Pyhton 3 opening modes are:

'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)

The modes r, w, x, a are combined with the mode modifiers b or t. + is optionally added, U should be avoided.

As I found out the hard way, it is a good idea to always specify t when opening a file in text mode since r is an alias for rt in the standard open() function but an alias for rb in the open() functions of all compression modules (when e.g. reading a *.bz2 file).

Thus the modes for opening a file should be:

rt / wt / xt / at for reading / writing / creating / appending to a file in text mode and

rb / wb / xb / ab for reading / writing / creating / appending to a file in binary mode.

Use + as before.

mode con lines=32766

sets the buffer, but also increases the window height to full screen, which is ugly.

You can change the settings directly in the registry :

:: escape the environment variable in the key name
set mySysRoot=%%SystemRoot%%

:: 655294544 equals 9999 lines in the GUI
reg.exe add "HKCU\Console\%mySysRoot%_system32_cmd.exe" /v ScreenBufferSize /t REG_DWORD /d 655294544 /f

:: We also need to change the Window Height, 3276880 = 50 lines
reg.exe add "HKCU\Console\%mySysRoot%_system32_cmd.exe" /v WindowSize /t REG_DWORD /d 3276880 /f

The next cmd.exe you start has the increase buffer.

So this doesn't work for the cmd.exe you are already in, but just use this in a pre-batch.cmd which than calls your main script.

Use scipy's Rotation.from_rotvec(). The argument is the rotation vector (a unit vector) multiplied by the rotation angle in rads.

from scipy.spatial.transform import Rotation
from numpy.linalg import norm


v = [3, 5, 0]
axis = [4, 4, 1]
theta = 1.2

axis = axis / norm(axis)  # normalize the rotation vector first
rot = Rotation.from_rotvec(theta * axis)

new_v = rot.apply(v)  
print(new_v)    # results in [2.74911638 4.77180932 1.91629719]

There are several more ways to use Rotation based on what data you have about the rotation:

• from_quat Initialized from quaternions.

• from_dcm Initialized from direction cosine matrices.

• from_euler Initialized from Euler angles.

I don't know if this is exactly what you want, but did you know you can use the CSS overflow property to create scrollbars?

CSS:

div.box{
  width: 200px;
  height: 200px;
  overflow: scroll;
}

HTML:

<div class="box">
  All your text content...
</div>

There are already a lot of good responses to this question, but I thought it may be helpful to clarify the case where you would expect the session cookie to be sent because the cookie domain matches, but it is not getting sent because the AJAX request is being made to a different subdomain. In this case, I have a cookie that is assigned to the *.mydomain.com domain, and I am wanting it to be included in an AJAX request to different.mydomain.com". By default, the cookie does not get sent. You do not need to disable HTTPONLY on the session cookie to resolve this issue. You only need to do what wombling suggested (https://stackoverflow.com/a/23660618/545223) and do the following.

1) Add the following to your ajax request.

xhrFields: { withCredentials:true }

2) Add the following to your response headers for resources in the different subdomain.

Access-Control-Allow-Origin : http://original.mydomain.com
Access-Control-Allow-Credentials : true

As Hogan notes above, use an AND instead of &. See this tutorial for more info.

Try this

rails destroy model Rating

It will remove model, migration, tests and fixtures

For everyone here seeking a crazy solution, just simply try

title="your-tooltip-here"

in any tag. I've tested into td's and a's and it pretty works.

I like it when the return value always equals the argument. This way, if the string array has been allocated with malloc(), it can safely be free() again.

/* Remove leading whitespaces */
char *ltrim(char *const s)
{
        size_t len;
        char *cur;

        if(s && *s) {
                len = strlen(s);
                cur = s;

                while(*cur && isspace(*cur))
                        ++cur, --len;

                if(s != cur)
                        memmove(s, cur, len + 1);

        }

        return s;
}

/* Remove trailing whitespaces */
char *rtrim(char *const s)
{
        size_t len;
        char *cur;

        if(s && *s) {
                len = strlen(s);
                cur = s + len - 1;

                while(cur != s && isspace(*cur))
                        --cur, --len;

                cur[isspace(*cur) ? 0 : 1] = '\0';
        }

        return s;
}

/* Remove leading and trailing whitespaces */
char *trim(char *const s)
{
        rtrim(s);  // order matters
        ltrim(s);

        return s;
}

If you want to see what is run in the database use dd(DB::getQueryLog()) to see what queries were run.

Try this

BookingDates::where('email', Input::get('email'))
    ->orWhere('name', 'like', '%' . Input::get('name') . '%')->get();

You can reload using /etc/init.d/nginx reload and sudo service nginx reload

If nginx -t throws some error then it won't reload

so use && to run both at a same time

like

nginx -t && /etc/init.d/nginx reload

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

Expanding P.Bailey's solution:

String.prototype.repeat = function(num) {
    return new Array(isNaN(num)? 1 : ++num).join(this);
    }

This way you should be safe from unexpected argument types:

var foo = 'bar';
alert(foo.repeat(3));              // Will work, "barbarbar"
alert(foo.repeat('3'));            // Same as above
alert(foo.repeat(true));           // Same as foo.repeat(1)

alert(foo.repeat(0));              // This and all the following return an empty
alert(foo.repeat(false));          // string while not causing an exception
alert(foo.repeat(null));
alert(foo.repeat(undefined));
alert(foo.repeat({}));             // Object
alert(foo.repeat(function () {})); // Function

EDIT: Credits to jerone for his elegant ++num idea!

@Html.DropDownListFor(m => m.Departments.id, (SelectList)ViewBag.Department, "Select", htmlAttributes: new { @class = "form-control" })

Try this:

SELECT Count(Student_ID) as 'StudentCount' 
FROM CourseSemOne
where Student_ID=3 
Having Count(Student_ID) < 6 and Count(Student_ID) > 0;

I would like just to add that if you want to use windows socket library you have to :

• at the beginning : call WSAStartup()

• at the end : call WSACleanup()

You can create a new group with both the apache user and FTP user as members and then make the permission on the upload folder 775. This should give both the apache and FTP users the ability to write to the files in the folder but keep everyone else from modifying them.

try this

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
    <url-pattern>*.css</url-pattern>
    <url-pattern>*.ico</url-pattern>
    <url-pattern>*.png</url-pattern>
    <url-pattern>*.jpg</url-pattern>
    <url-pattern>*.htc</url-pattern>
    <url-pattern>*.gif</url-pattern>

Edit: This is only valid for the servlet 2.5 spec and up.

Under Chrome v51 on a Mac, I found the rendering settings by clicking in the upper right corner, choosing More tools > Rendering settings and checking the Emulate media button in the options offered at the bottom of the window.

Thank you to all the other posters that led me to this, and credit to those that provided the answer without the images.

This functionality can also be added using JavaScript. Carto.net has an example:

http://old.carto.net/papers/svg/textFlow/

Something else that also might be useful to are you are editable text areas:

http://old.carto.net/papers/svg/gui/textbox/

Another solution cold be:

$value = $arr[count($arr) - 1];

The above will count the amount of array values, substract 1 and then return the value.

Note: This can only be used if your array keys are numeric.

There is an excellent summary of this feature in the article The For-Each Loop. It shows by example how using the for-each style can produce clearer code that is easier to read and write.

See the section "5.1. Accessing Hibernate APIs from JPA" in the Hibernate ORM User Guide:

Session session = entityManager.unwrap(Session.class);

You can either use onclick inside the button to ensure the event is preserved, or else attach the button click handler by finding the button after it is inserted. The test.html() call will not serialize the event.

I'm not sure that the method that you give is really inefficient, but an alternate way, as long as it doesn't have to be flexible in the length or padding character, would be (assuming that you want to pad it with "0" to 10 characters:

DECLARE
   @pad_characters VARCHAR(10)

SET @pad_characters = '0000000000'

SELECT RIGHT(@pad_characters + @str, 10)

This is not answering the problem but if anyone comes to this question when they stumble upon this exception of no suitable message converter found, here is my problem and solution.

In Spring 4.0.9, we were able to send this

    JSONObject jsonCredential = new JSONObject();
    jsonCredential.put(APPLICATION_CREDENTIALS, data);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);

ResponseEntity<String> res = restTemplate.exchange(myRestUrl), HttpMethod.POST,request, String.class);

In Spring 4.3.5 release, we starting seeing errors with the message that converter was not found.

The way Convertors work is that if you have it in your classpath, they get registered.

Jackson-asl was still in classpath but was not being recognized by spring. We replaced Jackson-asl with faster-xml jackson core.

Once we added I could see the converter being registered.

Install opencv-python (which is an unofficial pre-built OpenCV package for Python) by issuing the following command:

pip install opencv-python

Try using

img.style.webkitTransform = "rotate(60deg)"

I had a similar issue and this is how I was able to address it.

Step 1 - Loaded the data from hive table into another table as follows

DROP TABLE IF EXISTS TestHiveTableCSV; CREATE TABLE TestHiveTableCSV ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' AS SELECT Column List FROM TestHiveTable;

Step 2 - Copied the blob from hive warehouse to the new location with appropriate extension

Start-AzureStorageBlobCopy -DestContext $destContext -SrcContainer "Source Container" -SrcBlob "hive/warehouse/TestHiveTableCSV/000000_0" -DestContainer "Destination Container" ` -DestBlob "CSV/TestHiveTable.csv"

Hope this helps!

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

If you want to make transformation your app setting from web config file to web.Release.config,you have to do the following steps. Let your web.config app setting file is this-

<appSettings>
     <add key ="K1" value="Debendra Dash"/>
  </appSettings>

Now here is the web.Release.config for the transformation.

<appSettings>
    <add key="K1" value="value dynamicly from Realease"
       xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"   
         />
  </appSettings>

This will transform the value of K1 to the new value in realese Mode.

Another easy way is to set the logger like this- ensure that you do it before you load the cxf web service related classes. You can use it in some static blocks.

YourClientConstructor() {

  LogUtils.setLoggerClass(org.apache.cxf.common.logging.Log4jLogger.class);

  URL wsdlURL = YOurURL;//

  //create the service
  YourService = new YourService(wsdlURL, SERVICE_NAME);
  port = yourService.getServicePort(); 

  Client client = ClientProxy.getClient(port);
  client.getInInterceptors().add(new LoggingInInterceptor());
  client.getOutInterceptors().add(new LoggingOutInterceptor());
}

Then the inbound and outbound messages will be printed to Log4j file instead of the console. Make sure your log4j is configured properly

It can be done using a single line:

perl -pi.back -e 's/oldString/newString/g;' inputFileName

Pay attention that oldString is processed as a Regular Expression.
In case the string contains any of {}[]()^$.|*+? (The special characters for Regular Expression syntax) make sure to escape them unless you want it to be processed as a regular expression.
Escaping it is done by \, so \[.

If you are using terminal just type the following:

locate my.cnf

I think both have their place. One issue with using @property is that it is hard to extend the behaviour of getters or setters in subclasses using standard class mechanisms. The problem is that the actual getter/setter functions are hidden in the property.

You can actually get hold of the functions, e.g. with

class C(object):
    _p = 1
    @property
    def p(self):
        return self._p
    @p.setter
    def p(self, val):
        self._p = val

you can access the getter and setter functions as C.p.fget and C.p.fset, but you can't easily use the normal method inheritance (e.g. super) facilities to extend them. After some digging into the intricacies of super, you can indeed use super in this way:

# Using super():
class D(C):
    # Cannot use super(D,D) here to define the property
    # since D is not yet defined in this scope.
    @property
    def p(self):
        return super(D,D).p.fget(self)

    @p.setter
    def p(self, val):
        print 'Implement extra functionality here for D'
        super(D,D).p.fset(self, val)

# Using a direct reference to C
class E(C):
    p = C.p

    @p.setter
    def p(self, val):
        print 'Implement extra functionality here for E'
        C.p.fset(self, val)

Using super() is, however, quite clunky, since the property has to be redefined, and you have to use the slightly counter-intuitive super(cls,cls) mechanism to get an unbound copy of p.

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

With delay and fade :

setTimeout(function(){
    $(".alert").each(function(index){
        $(this).delay(200*index).fadeTo(1500,0).slideUp(500,function(){
            $(this).remove();
        });
    });
},2000);

Even i recently had the same query....some how none of the above mentioned setmaxzoom or else map:cameraZoom="13" did not work So i found that the depenedency which i used was old please make sure your dependency for google maps is correct this is the newest use this

This is a little ugly, but maybe someone will chime in with a prettier solution.

In most cases, when you find yourself using forEach on a Stream, you should rethink whether you are using the right tool for your job or whether you are using it the right way.

Generally, you should look for an appropriate terminal operation doing what you want to achieve or for an appropriate Collector. Now, there are Collectors for producing Maps and Lists, but no out of-the-box collector for combining two different collectors, based on a predicate.

Now, this answer contains a collector for combining two collectors. Using this collector, you can achieve the task as

Pair<Map<KeyType, Animal>, List<KeyType>> pair = animalMap.entrySet().stream()
    .collect(conditional(entry -> entry.getValue() != null,
            Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue),
            Collectors.mapping(Map.Entry::getKey, Collectors.toList()) ));
Map<KeyType,Animal> myMap = pair.a;
List<KeyType> myList = pair.b;

But maybe, you can solve this specific task in a simpler way. One of you results matches the input type; it’s the same map just stripped off the entries which map to null. If your original map is mutable and you don’t need it afterwards, you can just collect the list and remove these keys from the original map as they are mutually exclusive:

List<KeyType> myList=animalMap.entrySet().stream()
    .filter(pair -> pair.getValue() == null)
    .map(Map.Entry::getKey)
    .collect(Collectors.toList());

animalMap.keySet().removeAll(myList);

Note that you can remove mappings to null even without having the list of the other keys:

animalMap.values().removeIf(Objects::isNull);

or

animalMap.values().removeAll(Collections.singleton(null));

If you can’t (or don’t want to) modify the original map, there is still a solution without a custom collector. As hinted in Alexis C.’s answer, partitioningBy is going into the right direction, but you may simplify it:

Map<Boolean,Map<KeyType,Animal>> tmp = animalMap.entrySet().stream()
    .collect(Collectors.partitioningBy(pair -> pair.getValue() != null,
                 Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue)));
Map<KeyType,Animal> myMap = tmp.get(true);
List<KeyType> myList = new ArrayList<>(tmp.get(false).keySet());

The bottom line is, don’t forget about ordinary Collection operations, you don’t have to do everything with the new Stream API.

I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.

Finally i have found a solution with javascript here is the link bellow :-

scrollable horizontal and vertical grid view with fixed headers

I had some directories left from another mysql(8.0) installation, that were not removed.

I solved this by doing the following:

First uninstall mysql

brew uninstall [email protected]

Delete the folders/files that were not removed

rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf

Reinstall mysql and link it

brew install [email protected]
brew link --force [email protected]

Enable and start the service

brew services start [email protected]

I assume you want to know the performance difference between the following:

WHERE foo IN ('a', 'b', 'c')
WHERE foo = 'a' OR foo = 'b' OR foo = 'c'

According to the manual for MySQL if the values are constant IN sorts the list and then uses a binary search. I would imagine that OR evaluates them one by one in no particular order. So IN is faster in some circumstances.

The best way to know is to profile both on your database with your specific data to see which is faster.

I tried both on a MySQL with 1000000 rows. When the column is indexed there is no discernable difference in performance - both are nearly instant. When the column is not indexed I got these results:

SELECT COUNT(*) FROM t_inner WHERE val IN (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000);
1 row fetched in 0.0032 (1.2679 seconds)

SELECT COUNT(*) FROM t_inner WHERE val = 1000 OR val = 2000 OR val = 3000 OR val = 4000 OR val = 5000 OR val = 6000 OR val = 7000 OR val = 8000 OR val = 9000;
1 row fetched in 0.0026 (1.7385 seconds)

So in this case the method using OR is about 30% slower. Adding more terms makes the difference larger. Results may vary on other databases and on other data.

There's no NotifyIcon for WPF.

A colleague of mine used this freely available library to good effect:

• http://www.hardcodet.net/wpf-notifyicon (blog post)
• https://bitbucket.org/hardcodet/notifyicon-wpf/src (source code)
• https://www.nuget.org/packages/Hardcodet.NotifyIcon.Wpf/ (NuGet package)
• http://visualstudiogallery.msdn.microsoft.com/aacbc77c-4ef6-456f-80b7-1f157c2909f7/

You can set an enviroment variable to always have these options apply to all less'd file:

export LESS='-RS#3NM~g'

What I believe is this:

Cohesion refers to the degree to which the elements of a module/class belong together, it is suggested that the related code should be close to each other, so we should strive for high cohesion and bind all related code together as close as possible. It has to do with the elements within the module/class.

Coupling refers to the degree to which the different modules/classes depend on each other, it is suggested that all modules should be independent as far as possible, that's why low coupling. It has to do with the elements among different modules/classes.

To visualize the whole picture will be helpful:

If only one checkbox should be checked in the same time use RadioButtonFor instead:

      @Html.RadioButtonFor(model => model.Type,1, new { @checked = "checked" }) fultime
      @Html.RadioButtonFor(model => model.Type,2) party
      @Html.RadioButtonFor(model => model.Type,3) next option...

If one more one could be checked in the same time use excellent extension: CheckBoxListFor:

The answer of the user load step worked for me. Sometimes is need edit the file in /etc/mysql/my.cnf add line to client

[client]
password = your_mysql_root_password
port  = 3306
host  = 127.0.0.1
socket  = /var/lib/mysql/mysql.sock

I was interested to see that the original poster used a style that avoided early exits. Single Entry; Single Exit (SESE) is an interesting style that I've not really explored. It's late and I've got a bottle of cider, so I've written a solution (not tested) without an early exit.

I should have used an iterator. Unfortunately java.util.Iterator has a side-effect in the get method. (I don't like the Iterator design due to its exception ramifications.)

private Dog findDog(int id) {
    int i = 0;
    for (; i!=dogs.length() && dogs.get(i).getID()!=id; ++i) {
        ;
    }

    return i!=dogs.length() ? dogs.get(i) : null;
}

Note the duplication of the i!=dogs.length() expression (could have chosen dogs.get(i).getID()!=id).

Try this it worked for me

Write this in your Controller

public class DemoController: Controller

        public async Task<FileStreamResult> GetLogoImage(string logoimage)
        {
            string str = "" ;
            var filePath = Server.MapPath("~/App_Data/" + SubfolderName);//If subfolder exist otherwise leave.
            // DirectoryInfo dir = new DirectoryInfo(filePath);
            string[] filePaths = Directory.GetFiles(@filePath, "*.*");
            foreach (var fileTemp in filePaths)
            {
                  str= fileTemp.ToString();
            }
                return File(new MemoryStream(System.IO.File.ReadAllBytes(str)), System.Web.MimeMapping.GetMimeMapping(str), Path.GetFileName(str));
        }

Here is my view

<div><a href="/DemoController/GetLogoImage?Type=Logo" target="_blank">Download Logo</a></div>

Don'y forget that if you are mixing grouped (ie. SUM) fields and non-grouped fields, you need to GROUP BY one of the non-grouped fields.

Try this:

SELECT SUM(something) AS fieldname
FROM tablename
ORDER BY fieldname

OR this:

SELECT Field1, SUM(something) AS Field2
FROM tablename
GROUP BY Field1
ORDER BY Field2

And you can always do a derived query like this:

SELECT
   f1, f2
FROM
    (
        SELECT SUM(x+y) as f1, foo as F2
        FROM tablename 
        GROUP BY f2
    ) as table1
ORDER BY 
    f1

Many possibilities!

in the file .eslintrc.json in side roles add this code it will solve this issue

      "rules": {
    "prettier/prettier": ["error",{
      "endOfLine": "auto"}
    ]

  }

Just use special `

var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;

You can see more examples here.

You need to use *

0 */6 * * * /path/to/mycommand

Also you can refer to https://crontab.guru/ which will help you in scheduling better...

Use nargs='?' (or nargs='*' if you need more than one dir)

parser.add_argument('dir', nargs='?', default=os.getcwd())

extended example:

>>> import os, argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
_StoreTrueAction(option_strings=['-v'], dest='v', nargs=0, const=True, default=False, type=None, choices=None, help=None, metavar=None)
>>> parser.add_argument('dir', nargs='?', default=os.getcwd())
_StoreAction(option_strings=[], dest='dir', nargs='?', const=None, default='/home/vinay', type=None, choices=None, help=None, metavar=None)
>>> parser.parse_args('somedir -v'.split())
Namespace(dir='somedir', v=True)
>>> parser.parse_args('-v'.split())
Namespace(dir='/home/vinay', v=True)
>>> parser.parse_args(''.split())
Namespace(dir='/home/vinay', v=False)
>>> parser.parse_args(['somedir'])
Namespace(dir='somedir', v=False)
>>> parser.parse_args('somedir -h -v'.split())
usage: [-h] [-v] [dir]

positional arguments:
  dir

optional arguments:
  -h, --help  show this help message and exit
  -v

You don't mention the API version, but since API 11 there's the method WebViewClient.shouldInterceptRequest

Maybe this could help?

I am not writing anything same here. Just a changelog note from PHP manual.

Changelog for continue

Version Description

7.0.0 - continue outside of a loop or switch control structure is now detected at compile-time instead of run-time as before, and triggers an E_COMPILE_ERROR.

5.4.0   continue 0; is no longer valid. In previous versions it was interpreted the same as continue 1;.

5.4.0   Removed the ability to pass in variables (e.g., $num = 2; continue $num;) as the numerical argument.

Changelog for break

Version Description

7.0.0   break outside of a loop or switch control structure is now detected at compile-time instead of run-time as before, and triggers an E_COMPILE_ERROR.

5.4.0   break 0; is no longer valid. In previous versions it was interpreted the same as break 1;.

5.4.0   Removed the ability to pass in variables (e.g., $num = 2; break $num;) as the numerical argument.

No, image/jpg is not the same as image/jpeg.

You should use image/jpeg. Only image/jpeg is recognised as the actual mime type for JPEG files.

See https://tools.ietf.org/html/rfc3745, https://www.w3.org/Graphics/JPEG/ .

Serving the incorrect Content-Type of image/jpg to IE can cause issues, see http://www.bennadel.com/blog/2609-internet-explorer-aborts-images-with-the-wrong-mime-type.htm.

I used the following online tool: https://www.get-metadata.com It allows to upload a file and analyze it and then shows all its metadata.

For adhoc queries:

Show results in grid mode (CTRL+D), run query, click top left hand box in results grid, paste to Excel, save as CSV. You may be able to paste directly into a text file (can't try it now)

Or "Results to file" has options too for CSV

Or "Results to text" with comma separators

All settings under Tool..Options and Query.. options (I think, can't check) too

Besides listing the files explicitly as shown by unwind and Wienczny, you can setup change lists and checkin these. These allow you to manage disjunct sets of changes to the same working copy.

You can read about them in the online version of the excellent SVN book.

An evolution of what BioData41 added...

Place what follows in CSS style

     <style>

        .CellWithComment{position:relative;}

        .CellComment
        {
            visibility: hidden;
            width: auto;
            position:absolute; 
            z-index:100;
            text-align: Left;
            opacity: 0.4;
            transition: opacity 2s;
            border-radius: 6px;
            background-color: #555;
            padding:3px;
            top:-30px; 
            left:0px;
        }   
        .CellWithComment:hover span.CellComment {visibility: visible;opacity: 1;}
</style>

Then, use it like this:

        <table>
            <tr>
                <th class="CellWithComment">Category<span class="CellComment">"Ciaooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo"</span></th>
                <th class="CellWithComment">Code<span class="CellComment">"Ciaooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo"</span></th>
                <th>Opened</th>
                <th>Event</th>
                <th>Severity</th>           
                <th>Id</th>
                <th>Component Name</th>
            </tr>
            <tr>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
            </tr>
            <tr>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
                <td>Table cell</td>
            </tr>
        </table>

Another way to do it:

MEDIA_ROOT = '/home/USER/Projects/REPO/src/PROJECT/APP/static/media/'
MEDIA_URL = '/static/media/'

This would require you to move your media folder to a sub directory of a static folder.

Then in your template you can use:

<img class="scale-with-grid" src="{{object.photo.url}}"/>

I think you might want something like this

// Compose a string that consists of three lines.
string lines = "First line.\r\nSecond line.\r\nThird line.";

// Write the string to a file.
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt");
file.WriteLine(lines);

file.Close();

Updated 2018-06-08: My previous answer was a bit of hack so I have come back and looked at this again. This is a cleaner Jinja2 approach.

- name: Set fact 4
  set_fact:
    foo: "{% for i in foo_result.results %}{% do foo.append(i) %}{% endfor %}{{ foo }}"

I am adding this answer as current best answer for Ansible 2.2+ does not completely cover the original question. Thanks to Russ Huguley for your answer this got me headed in the right direction but it left me with a concatenated string not a list. This solution gets a list but becomes even more hacky. I hope this gets resolved in a cleaner manner.

- name: build foo_string
  set_fact:
    foo_string: "{% for i in foo_result.results %}{{ i.ansible_facts.foo_item }}{% if not loop.last %},{% endif %}{%endfor%}"

- name: set fact foo
  set_fact:
    foo: "{{ foo_string.split(',') }}"

Im under the impression that theres no way to do this, it would be nice though.

You can achieve a similar result by having a Alarm_last_set_time recorded somewhere, and having a On_boot_starter BroadcastReciever:BOOT_COMPLETED kinda thing.

You could use a variable table, like this:

declare @num int

set @num = 1

declare @results table ( val int )

while (@num < 6)
begin
  insert into @results ( val ) values ( @num )
  set @num = @num + 1
end

select val from @results

From the JDK source:

static <T> Function<T, T> identity() {
    return t -> t;
}

So, no, as long as it is syntactically correct.

This code can do the trick as well, using the SCSS syntax

.parent {
  & > * {
    margin-right: 15px;
    &:last-child {
      margin-right: 0;
    }
  }
}

I had the same issue, but I have just figured out that :

• parsing the EditText value in the Oncreate method caused the app to crash because when the app starts, there are no values to parse or maybe the placeholders which are letter.

My code:

package com.example.herodav.volumeapp;

import android.renderscript.Double2;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.*;
import android.widget.*;

import org.w3c.dom.Text;

public class MainActivity extends AppCompatActivity {

    EditText height, length, depth;
    TextView volume;
    double h,l,d,vol;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        height = (EditText)findViewById(R.id.h);
        length = (EditText)findViewById(R.id.l);
        depth = (EditText)findViewById(R.id.d);
        volume = (TextView)findViewById(R.id.v);

        Button btn = (Button)findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                calculateVolume();
                volume.setText("Volume = " + String.valueOf(vol));
            }
        });
    }

    public void calculateVolume(){
        h = Double.parseDouble(height.getText().toString());
        l = Double.parseDouble(length.getText().toString());
        d = Double.parseDouble(depth.getText().toString());
        vol = h*l*d;
    }
}

it's so easy...converting a date to calendar like this:

Calendar cal=Calendar.getInstance();
DateFormat format=new SimpleDateFormat("yyyy/mm/dd");
format.format(date);
cal=format.getCalendar();

You can combine AngularJS and jQuery. For example, you need to define an array, $scope.selected = [];, in the controller.

<label ng-repeat="item in items">
    <input type="checkbox" ng-model="selected[$index]" ng-true-value="'{{item}}'">{{item}}
</label>

You can get an array owning the selected items. Using method alert(JSON.stringify($scope.selected)), you can check the selected items.

You can also use python's requests library instead.

import requests

url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'    
response = requests.get(url)    
dict = response.json()

Now you can manipulate the "dict" like a python dictionary.

I have written a simple base class that handles this. It's available as a NuGet package and it's quite easy to use.

//MemberServiceClient is the class generated by SvcUtil
public class MemberServiceManager : ServiceClientBase<MemberServiceClient>
{
    public User GetUser(int userId)
    {
        return PerformServiceOperation(client => client.GetUser(userId));
    }

    //you can also check if any error occured if you can't throw exceptions       
    public bool TryGetUser(int userId, out User user)
    {
        return TryPerformServiceOperation(c => c.GetUser(userId), out user);
    }
}

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

The solution for the error is to add this line at the top of the code:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

Go to the repository folder. Delete relevant submodules from .gitmodules. Select show hidden files. Go to .git folder, delete the submodules from module folder and config.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

First of all, don't loop while (!eof()), it will not work as you expect it to because the eofbit will not be set until after a failed read due to end of file.

Secondly, the normal input operator >> separates on whitespace and so can be used to read "words":

std::string word;
while (file >> word)
{
    ...
}

Add your style here:

If you just want to know whether the certificate has expired (or will do so within the next N seconds), the -checkend <seconds> option to openssl x509 will tell you:

if openssl x509 -checkend 86400 -noout -in file.pem
then
  echo "Certificate is good for another day!"
else
  echo "Certificate has expired or will do so within 24 hours!"
  echo "(or is invalid/not found)"
fi

This saves having to do date/time comparisons yourself.

openssl will return an exit code of 0 (zero) if the certificate has not expired and will not do so for the next 86400 seconds, in the example above. If the certificate will have expired or has already done so - or some other error like an invalid/nonexistent file - the return code is 1.

(Of course, it assumes the time/date is set correctly)

Be aware that older versions of openssl have a bug which means if the time specified in checkend is too large, 0 will always be returned (https://github.com/openssl/openssl/issues/6180).

var newList = list.OrderBy(x => x.Product.Name).Reverse()

This should do the job.

For me, line numbers wouldn't appear in the editor until I added the option under both the "all languages" pane, and the language I was working under (C# etc)... screen capture showing editor options

Change maxDate to current date

maxDate: new Date()

It will set current date as maximum value.

I quite like adding the code in the GridView RowDataBound event to inform the user exactly which item they are trying to delete. Slightly better user experience?

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

    if (e.Row.RowType == DataControlRowType.DataRow)

        // Use whatever control you want to show in the confirmation message
        Label lblContactName = e.Row.FindControl("lblContactName") as Label;

Like Jonathan said, yes, renaming can help to work around this problem. But ,e.g. I was forced to rename target executable many times, it's some tedious and not good.

The problem lies there that when you run your project and later get an error that you can't build your project - it's so because this executable (your project) is still runnning (you can check it via task manager.) If you just rename target build, some time later you will get the same error with new name too and if you open a task manager, you will see that you rubbish system with your not finished projects.

Visual studio for making a new build need to remove previous executable and create new instead of old, it can't do it while executable is still runinng. So, if you want to make a new build, process of old executable has to be closed! (it's strange that visual studio doesn't close it by itself and yes, it looks like some buggy behaviour).

It's some tedious to do it manually, so you may just a bat file and just click it when you have such problem:

taskkill /f /im name_of_target_executable.exe

it works for me at least. Like a guess - I don't close my program properly in C++, so may be it's normal for visual studio to hold it running.

ADDITION: There is a great chance to be so , because of not finished application. Check whether you called PostQuitMessage in the end, in order to give know Windows that you are done.

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

<input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.

products = [{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}];

change to

products = '[{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}]';

If I'm not wrong, what you're trying to achieve is called Sticky navbar.

With a few lines of jQuery and the scroll event is pretty easy to achieve:

$(document).ready(function() {

    var menu = $('.menu');
    var content = $('.content');
    var origOffsetY = menu.offset().top;

    function scroll() {
        if ($(window).scrollTop() >= origOffsetY) {
            menu.addClass('sticky');
            content.addClass('menu-padding');
        } else {
            menu.removeClass('sticky');
            content.removeClass('menu-padding');
        }
    }

    $(document).scroll();

});

I've done a quick working sample for you, hope it helps: http://jsfiddle.net/yeco/4EcFf/

To make it work with Bootstrap you only need to add or remove "navbar-fixed-top" instead of the "sticky" class in the jsfiddle .

I’ve seen people doing it with raw queries, like this:

$q->where(DB::raw("DATE(created_at) = '".date('Y-m-d')."'"));

Or without raw queries by datetime, like this:

$q->where('created_at', '>=', date('Y-m-d').' 00:00:00'));

Luckily, Laravel Query Builder offers a more Eloquent solution:

$q->whereDate('created_at', '=', date('Y-m-d'));

Or, of course, instead of PHP date() you can use Carbon:

$q->whereDate('created_at', '=', Carbon::today()->toDateString());

It’s not only whereDate. There are three more useful functions to filter out dates:

$q->whereDay('created_at', '=', date('d'));
$q->whereMonth('created_at', '=', date('m'));
$q->whereYear('created_at', '=', date('Y'));

I wrote a cron job to grab the ip address of my dads router and ftp it to a secure location so when he needed help I could remote desktop in and fix his comp.

you can achieve that using Following example uses addBatch & executeBatch commands to execute multiple SQL commands simultaneously.

Batch Processing allows you to group related SQL statements into a batch and submit them with one call to the database. reference

When you send several SQL statements to the database at once, you reduce the amount of communication overhead, thereby improving performance.

• JDBC drivers are not required to support this feature. You should use the DatabaseMetaData.supportsBatchUpdates() method to determine if the target database supports batch update processing. The method returns true if your JDBC driver supports this feature.
• The addBatch() method of Statement, PreparedStatement, and CallableStatement is used to add individual statements to the batch. The executeBatch() is used to start the execution of all the statements grouped together.
• The executeBatch() returns an array of integers, and each element of the array represents the update count for the respective update statement.
• Just as you can add statements to a batch for processing, you can remove them with the clearBatch() method. This method removes all the statements you added with the addBatch() method. However, you cannot selectively choose which statement to remove.

EXAMPLE:

import java.sql.*;

public class jdbcConn {
   public static void main(String[] args) throws Exception{
      Class.forName("org.apache.derby.jdbc.ClientDriver");
      Connection con = DriverManager.getConnection
      ("jdbc:derby://localhost:1527/testDb","name","pass");

      Statement stmt = con.createStatement
      (ResultSet.TYPE_SCROLL_SENSITIVE,
      ResultSet.CONCUR_UPDATABLE);
      String insertEmp1 = "insert into emp values
      (10,'jay','trainee')";
      String insertEmp2 = "insert into emp values
      (11,'jayes','trainee')";
      String insertEmp3 = "insert into emp values
      (12,'shail','trainee')";
      con.setAutoCommit(false);
      stmt.addBatch(insertEmp1);//inserting Query in stmt
      stmt.addBatch(insertEmp2);
      stmt.addBatch(insertEmp3);
      ResultSet rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows before batch execution= "
      + rs.getRow());
      stmt.executeBatch();
      con.commit();
      System.out.println("Batch executed");
      rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows after batch execution= "
      + rs.getRow());
   }
}

In similar situations, I've done well by putting something like the following into /etc/rc.local:

cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local  # check that rc.local ran

This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.

You can also:

public static int unsignedToBytes(byte a)
{
    return (int) ( ( a << 24) >>> 24);
}    

Explanation:

let's say a = (byte) 133;

In memory it's stored as: "1000 0101" (0x85 in hex)

So its representation translates unsigned=133, signed=-123 (as 2's complement)

a << 24

When left shift is performed 24 bits to the left, the result is now a 4 byte integer which is represented as:

"10000101 00000000 00000000 00000000" (or "0x85000000" in hex)

then we have

( a << 24) >>> 24

and it shifts again on the right 24 bits but fills with leading zeros. So it results to:

"00000000 00000000 00000000 10000101" (or "0x00000085" in hex)

and that is the unsigned representation which equals to 133.

If you tried to cast a = (int) a; then what would happen is it keeps the 2's complement representation of byte and stores it as int also as 2's complement:

(int) "10000101" ---> "11111111 11111111 11111111 10000101"

And that translates as: -123

Use git log to find the revision you want to rollback to, and take note of the commit hash. After that, you have 2 options:

1. If you plan to commit anything after that revision, I recommend you to checkout to a new branch: git checkout -b <new_branch_name> <hash>

2. If you don't plan to commit anything after that revision, you can simply checkout without a branch: git checkout <hash> - NOTE: This will put your repository in a 'detached HEAD' state, which means its currently not attached to any branch - then you'll have some extra work to merge new commits to an actual branch.

Example:

$ git log
commit 89915b4cc0810a9c9e67b3706a2850c58120cf75
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:15:01 2010 -0300

    Added a custom extension.

commit 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:13:48 2010 -0300

    Missing constness.

$ git checkout 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Note: moving to '4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7'
which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 4553c14... Missing constness.

That way you don't lose any informations, thus you can move to a newer revision when it becomes stable.

You can recursively revert like this:

svn revert --recursive .

There is no way (without writing a creative script) to remove things that aren't under source control. I think the closest you could do is to iterate over all of the files, use then grep the result of svn list, and if the grep fails, then delete it.

EDIT: The solution for the creative script is here: Automatically remove Subversion unversioned files

So you could create a script that combines a revert with whichever answer in the linked question suits you best.

Solution:

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

Demo Fiddle

I don't have enough reputation to reply to @complex857 solution. It works great, but I had to add ; at the end of the Content-Disposition header. Without it the browser adds two dashes at the end of the filename (e.g. instead of "export.csv" the file gets saved as "export.csv--"). Probably it tries to sanitize \r\n at the end of the header line.

Correct line should look like this:

header('Content-Disposition: attachment;filename="'.$filename.'";');

In case when CSV has UTF-8 chars in it, you have to change the encoding to UTF-8 by changing the Content-Type line:

header('Content-Type: application/csv; charset=UTF-8');

Also, I find it more elegant to use rewind() instead of fseek():

rewind($f);

Thanks for your solution!

I am using this method to avoid the popup blocker in my React code. it will work in all other javascript codes also.

When you are making an async call on click event, just open a blank window first and then write the URL in that later when an async call will complete.

const popupWindow = window.open("", "_blank");
popupWindow.document.write("<div>Loading, Plesae wait...</div>")

on async call's success, write the following

popupWindow.document.write(resonse.url)
