So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:

<script type="text/javascript">
  //<![CDATA[
    $(document).ready( function() {
       $('body').addClass( 'test' );
    } );
  //]]>
</script>

The following HAML will generate the typical tag for including (for example) typekit or google analytics code.

 %script{:type=>"text/javascript"}
  //your code goes here - dont forget the indent!

For prevent an error "can't modify frozen string" for encoding a varible you can use: var.dup.force_encoding(Encoding::ASCII_8BIT) or var.dup.force_encoding(Encoding::UTF_8)

ProxyWs proxy = (ProxyWs) factory.create();
Client client = ClientProxy.getClient(proxy);
HTTPConduit http = (HTTPConduit) client.getConduit();
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setConnectionTimeout(0);
httpClientPolicy.setReceiveTimeout(0);
http.setClient(httpClientPolicy);

This worked for me.

I resolved this by adding a new source folder and putting my java file inside that folder. "source folder" is not just any folder i believe. its some special folder type for java/eclipse and can be added in eclipse by right-click on project -> properties -> Java buld path -> Source and add a folder

Somewhere in the code you are using, there is a call to the Win32 API, CoCreateInstance, to dynamically load a DLL and instantiate an object from it.

The mapping between the component ID and the DLL that is capable of instantiating that object is usually found in HEKY_CLASSES_ROOT\CLSID in the registry. To discuss this further would be to explain a lot about COM in Windows. But the error indicates that the COM guid is not present in the registry.

I don't much about what the PackAndGo DLL is (an Autodesk component), but I suspect you simply need to "install" that component or the software package it came with through the designated installer to have that DLL and appropriate COM registry keys on your computer you are trying to run your code on. (i.e. go run setup.exe for this product).

In other words, I think you need to install "Pack and Go" on this computer instead of just copying the DLL to the target machine.

Also, make sure you decide to build your code appropriate as 32-bit vs. 64-bit depending on the which build flavor (32 or 64 bit) of Pack And Go you install.

The most recent approach of drawing underlined text is described by Romain Guy on medium with available source code on GitHub. This sample application exposes two possible implementations:

• A Path-based implementation that requires API level 19
• A Region-based implementation that requires API level 1

For those of us still lagging behind on Swift 2.3 here is Gordon's answer in our syntax:

let email = "[email protected]"
if let url = NSURL(string: "mailto:\(email)") {
   UIApplication.sharedApplication().openURL(url)
}

You should use the EndXXX of your async method to return the value. EndXXX should wait until there is a result using the IAsyncResult's WaitHandle and than return with the value.

for i in range(len(Data)):
    Data[i, 1] = Data[i-lookback:i, 0].sum() / lookback

Try this piece of code. I think it's simpler and does the job. lookback is the window of the moving average.

In the Data[i-lookback:i, 0].sum() I have put 0 to refer to the first column of the dataset but you can put any column you like in case you have more than one column.

First, choosing a data structure(xml,json,yaml) usually includes only a readability/size problem. For example

Json is very compact, but no human being can read it easily, very hard do debug,

Xml is very large, but everyone can easily read/debug it,

Yaml is in between Xml and json.

But if you want to work with Javascript heavily and/or your software makes a lot of data transfer between browser-server, you should use Json, because it is pure javascript and very compact. But don't try to write it in a string, use libraries to generate the code you needed from an object.

Hope this helps.

You can import a bunch of .java files to your existing project without creating a new project. Here are the steps:

1. Right-click on the Default Package in the Project Manager pane underneath your project and choose Import
2. An Import Wizard window will display. Choose File system and select the Next button
3. You are now prompted to choose a file
4. Simply browse your folder with .java files in it
5. Select desired .java files
6. Click on Finish to finish the import wizard

If you're needing something simple, would this fit the bill?

Map<K, V> myCache = Collections.synchronizedMap(new WeakHashMap<K, V>());

It wont save to disk, but you said you wanted simple...

Links:

• Collections.synchronizedMap
• WeakHashMap

(As Adam commented, synchronising a map has a performance hit. Not saying the idea doesn't have hairs on it, but would suffice as a quick and dirty solution.)

This will add a new column to your data.frame with the specified format.

df$Month_Yr <- format(as.Date(df$Date), "%Y-%m")

df
#>   ID       Date Month_Yr
#> 1  1 2004-02-06  2004-02
#> 2  2 2006-03-14  2006-03
#> 3  3 2007-07-16  2007-07

# your data sample
  df <- data.frame( ID=1:3,Date = c("2004-02-06" , "2006-03-14" , "2007-07-16") )

a simple example:

dates <- "2004-02-06"

format(as.Date(dates), "%Y-%m")
> "2004-02"

side note: the data.table approach can be quite faster in case you're working with a big dataset.

library(data.table)
setDT(df)[, Month_Yr := format(as.Date(Date), "%Y-%m") ]

$json = array('tag' => 'Odómetro'); // Original array
$json = json_encode($json); // {"Tag":"Od\u00f3metro"}
$json = json_decode($json); // Od\u00f3metro becomes  Odómetro
echo $json->{'tag'}; // Odómetro
echo utf8_decode($json->{'tag'}); // Odómetro

You were close, just use utf8_decode.

Running your code shows an image for me, after adjusting the path. Can you verify that your image path is correct, try absolute path for instance?

You have to loop through the list and fill your String[].

String[] array = new String[lst.size()];
int index = 0;
for (Object value : lst) {
  array[index] = (String) value;
  index++;
}

If the list would be of String values, List then this would be as simple as calling lst.toArray(new String[0]);

You can use inputmode html attribute:

<input type="text" inputmode="numeric" />

Bit late to the party, but this will get it done. I left the example at 600, as that is what most people will use:

Similar to Shay's example except this also includes max-width to work on the rest of the clients that do have support, as well as a second method to prevent the expansion (media query) which is needed for Outlook '11.

In the head:

  <style type="text/css">
    @media only screen and (min-width: 600px) { .maxW { width:600px !important; } }
  </style>

In the body:

<!--[if (gte mso 9)|(IE)]><table width="600" align="center" cellpadding="0" cellspacing="0" border="0"><tr><td><![endif]-->
<div class="maxW" style="max-width:600px;">

<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#FFFFFF">

Todo this in a single system call you can use the fs-extra npm module. After this the file will have been created as well as the directory it is to be placed in.

const fs = require('fs-extra');
const file = '/tmp/this/path/does/not/exist/file.txt'
fs.ensureFile(file, err => {
    console.log(err) // => null
});

Another way is to use ensureFileSync which will do the same thing but synchronous.

const fs = require('fs-extra');
const file = '/tmp/this/path/does/not/exist/file.txt'
fs.ensureFileSync(file)

Reposting this here for others from the requests issue page:

Requests' does not support doing this before version 1. Subsequent to version 1, you are expected to subclass the HTTPAdapter, like so:

from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager
import ssl

class MyAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                       maxsize=maxsize,
                                       block=block,
                                       ssl_version=ssl.PROTOCOL_TLSv1)

When you've done that, you can do this:

import requests
s = requests.Session()
s.mount('https://', MyAdapter())

Any request through that session object will then use TLSv1.

It's almost become a trend now to have a Conv2D followed by a ReLu followed by a BatchNormalization layer. So I made up a small function to call all of them at once. Makes the model definition look a whole lot cleaner and easier to read.

def Conv2DReluBatchNorm(n_filter, w_filter, h_filter, inputs):
    return BatchNormalization()(Activation(activation='relu')(Convolution2D(n_filter, w_filter, h_filter, border_mode='same')(inputs)))

This can be an issue when using Source Control and automated deployments to a shared development environment. Where I work we have a very large sample DB on our development tier to work with (a subset of our production data).

Recently I did some work to remove one column from a table and then add some extra ones on the end. I then had to undo my column removal so I re-added it on the end which means the table and all references are correct in the environment but the Source Control automated deployment will no longer work because it complains about the table definition changing.

The real problem here is that the table + indexes are ~120GB and the environment only has ~60GB free so I'll need to either:

a) Rename the existing columns which are in the wrong order, add new columns in the right order, update the data then drop the old columns

OR

b) Rename the table, create a new table with the correct order, insert to the new table from the old and delete from the old as I go along

The SSMS/TFS Schema compare option of using a temp table won't work because there isn't enough room on disc to do it.

I'm not trying to say this is the best way to go about things or that column order really matters, just that I have a scenario where it is an issue and I'm sharing the options I've thought of to fix the issue

All you need to do is use the file object as an iterator.

for line in open("log.txt"):
    do_something_with(line)

Even better is using context manager in recent Python versions.

with open("log.txt") as fileobject:
    for line in fileobject:
        do_something_with(line)

This will automatically close the file as well.

You need to include the getters and setters for all the fields that have been defined in the model Test class --

public class Test implements Serializable {

    private static final long serialVersionUID = -1764970284520387975L;

    public String name;

    public Test() {

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

PHP is likely the easiest.

Just make a file script.php that contains <?php shell_exec("yourscript.sh"); ?> and send anybody who clicks the button to that destination. You can return the user to the original page with header:

<?php
shell_exec("yourscript.sh");
header('Location: http://www.website.com/page?success=true');
?>

2017 answer: you can now do exactly what you want in every current browser and node

This is quite simple:

• Return a Promise
• Use the 'await', which will tell JavaScript to await the promise to be resolved into a value (like the HTTP response)
• Add the 'async' keyword to the parent function

Here's a working version of your code:

(async function(){

var response = await superagent.get('...')
console.log(response)

})()

await is supported in all current browsers and node 8

First, let's make some test data:

create table client (client_id integer not null primary key auto_increment,
                     name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
                        client_id integer references client.id,
                        cash decimal(10,2),
                        stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
                                                       (1, 10.11, 23.22),
                                                       (2, 30.30, 40.40),
                                                       (2, 40.40, 50.50);

If you didn't need the portfolio ID, it would be easy:

select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id

+-----------+----------+--------------------+
| client_id | name     | max(cash + stocks) |
+-----------+----------+--------------------+
|         1 | John Doe |              33.33 | 
|         2 | Jane Doe |              90.90 | 
+-----------+----------+--------------------+

Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:

select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id

+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
|         1 |    33.33 | 
|         2 |    90.90 | 
+-----------+----------+

Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:

 select portfolio_id, cash + stocks from portfolio 
 join (select client_id, max(cash + stocks) as maxtotal 
       from portfolio
       group by client_id) as maxima
 using (client_id)
 where cash + stocks = maxtotal

+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
|            5 |         33.33 | 
|            6 |         33.33 | 
|            8 |         90.90 | 
+--------------+---------------+

Finally, we can join to the client table (as you did) in order to include the name of each client:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         1 | John Doe |            6 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

You could put a hidden input on the page, and after the page loads, give it a value. Then you can check that field, if it was in the post data, it's a postback, otherwise it is not.

There were two solutions that used server side code (ASP.NET specific) posted as responses. I think it is worth pointing out that this solution is technology agnostic since it uses client side features only, which are available in all major browsers.

It's possible with Sass! The only thing you have to do is to url-encode your svg code. And this is possible with a helper function in Sass. I've made a codepen for this. Look at this:

http://codepen.io/philippkuehn/pen/zGEjxB

// choose a color

$icon-color: #F84830;


// functions to urlencode the svg string

@function str-replace($string, $search, $replace: '') {
  $index: str-index($string, $search);
  @if $index {
    @return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace);
  }
  @return $string;
}

@function url-encode($string) {
  $map: (
    "%": "%25",
    "<": "%3C",
    ">": "%3E",
    " ": "%20",

  );
  $new: $string;
  @each $search, $replace in $map {
    $new: str-replace($new, $search, $replace);
  }
  @return $new;
}

Essentially:

history.pushState('data', '', 'http://your-domain/path');

You can manipulate the history object to make this work.

It only works on the same domain, but since you're satisfied with using the hash tag approach, that shouldn't matter.

Obviously would need to be cross-browser tested, but since that was posted on the Opera forum I'm safe to assume it would work in Opera, and I just tested it in Chrome and it worked fine.

I don't think you need cookies. Each document's js code can access the other document elements. So you can use them directly to share data. Your first window w1 opens w2 and save the reference

var w2 = window.open(...) 

In w2 you can access w1 using the opener property of window.

Just complementing Hovercraft Full Of Eels's solution:

I reworked his code, tweaked it a bit, adding a grid, axis labels and now the Y-axis goes from the minimum value present up to the maximum value. I planned on adding a couple of getters/setters but I didn't need them, you can add them if you want.

      //split the hex into pairs
      String pair = hex.substring(i, (i + 2));
      //convert hex to decimal

             str="n/a";  
  return str;
}

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.

This is working fine for me :

public class MethodInvokerClass {
    public static void main(String[] args) throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, ClassNotFoundException, InvocationTargetException, InstantiationException {
        Class c = Class.forName(MethodInvokerClass.class.getName());
        Object o = c.newInstance();
        Class[] paramTypes = new Class[1];
        paramTypes[0]=String.class;
        String methodName = "countWord";
         Method m = c.getDeclaredMethod(methodName, paramTypes);
         m.invoke(o, "testparam");
}
public void countWord(String input){
    System.out.println("My input "+input);
}

}

Output:

My input testparam

I am able to invoke the method by passing its name to another method (like main).

You can access the version through a URL, the web GUI, and the ReST API.

Via a URL

An HTML page displaying the version can be displayed in a browser at https://your-gitlab-url/help. The version is displayed only if you are signed in.

Via a menu in the web GUI

If you do not care to type this URL, you can also access the same HTML page from a menu in the GitLab web GUI:

In GitLab 11 and later

1. Log in to GitLab
2. Click on the drop down menu in the upper right. Select Help.
3. The GitLab version appears at the top of the page

In earlier versions, like GitLab 9

1. Log in to GitLab
2. Click on the drop down menu in the upper left. Select Help.
3. And then the version appears at the top of the page

Via the ReST API

Log in as any user, select the user icon in the upper right of the screen. Select Settings > Access Tokens. Create a personal access token and copy it to your clipboard.

In a Linux shell, use curl to access the GitLab version:

curl --header "PRIVATE-TOKEN: personal-access-token" your-gitlab-url/api/v4/version

Don't use IDs at all if you don't need to, instead wrap the input in a label like this:

<label>
   My Label
   <input type="text"/>
</label>

Then you won't need to worry about unique IDs.

I found a solution by myself after doing some research:

• Go to Eclipse home folder.
• Search for 'android' => In Windows 7 you can use search bar.
• Delete all the file related to android, which is shown in the results.
• Restart Eclipse.
• Install the ADT plugin again and Restart plugin.

Now everything works fine.

This doesn't answer your question exactly but I thought it would be worth mentioning Materialized Views. My experience is mostly with Oracle but supposedly SQL-Server is fairly similar.

We used something similar in our architecture to address XML performance problems. Our systems are designed with a lot of data stored as XML on a row and applications might need to query particular values within it. Handling lots of XMLTypes and running XPaths across large number of rows has a large impact on performance so we use a form of materialized views to extract the desired XML nodes out into a relational table anytime the base table changes. This effectively provides a physical snapshot of the query at a point in time as opposed to standard views which would run their query on demand.

How about using FONT tag?

Like:

H<font color="red">E</font>LLO.

Can't show example here, because this site doesn't allow font tag use.

Span style is fast and easy too.

"saving" is something wholly different from changing paragraph content with jquery.

If you need to save changes you will have to write them to your server somehow (likely form submission along with all the security and input sanitizing that entails). If you have information that is saved on the server then you are no longer changing the content of a paragraph, you are drawing a paragraph with dynamic content (either from a database or a file which your server altered when you did the "saving").

Judging by your question, this is a topic on which you will have to do MUCH more research.

Input page (input.html):

<form action="/saveMyParagraph.php">
    <input name="pContent" type="text"></input>
</form>

Saving page (saveMyParagraph.php) and Ouput page (output.php):

Inserting Data Into a MySQL Database using PHP

I'll try to answer the why question: The Java array is very simple and rudimentary compared to classes like ArrayList, that are more dynamic. Java wants to know at declaration time how much memory should be allocated for the array. An ArrayList is much more dynamic and the size of it can vary over time.

If you initialize your array with the length of two, and later on it turns out you need a length of three, you have to throw away what you've got, and create a whole new array. Therefore the 'new' keyword.

In your first two examples, you tell at declaration time how much memory to allocate. In your third example, the array name becomes a pointer to nothing at all, and therefore, when it's initialized, you have to explicitly create a new array to allocate the right amount of memory.

I would say that (and if someone knows better, please correct me) the first example

AClass[] array = {object1, object2}

actually means

AClass[] array = new AClass[]{object1, object2};

but what the Java designers did, was to make quicker way to write it if you create the array at declaration time.

The suggested workarounds are good. If the time or memory usage is critical at runtime, use arrays. If it's not critical, and you want code that is easier to understand and to work with, use ArrayList.

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

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

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

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

Updated

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

Within the constructor of GalzyTable2 you are doing...

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

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

Case in point...

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

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

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

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

You can also try using multiprocessing.Process with daemon=True; the process.start() method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.

I experienced similar problem while working with falcon framework and using daemon process helped.

You'd need to do the following:

from multiprocessing import Process

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    heavy_process = Process(  # Create a daemonic process with heavy "my_func"
        target=my_func,
        daemon=True
    )
    heavy_process.start()
    return Response(
        mimetype='application/json',
        status=200
    )

# Define some heavy function
def my_func():
    time.sleep(10)
    print("Process finished")

You should get a response immediately and, after 10s you should see a printed message in the console.

NOTE: Keep in mind that daemonic processes are not allowed to spawn any child processes.

Make sure to download these from here:

Also create PATH enviroment variable on you computer like this (if it doesn't exist already):

1. Right click on My Computer/Computer
2. Properties
3. Advanced system settings (or just Advanced)
4. Enviroment variables
5. If PATH variable doesn't exist among "User variables" click New (Variable name: PATH, Variable value : C:\Program Files\Java\jdk1.8.0\bin; <-- please check out the right version, this may differ as Oracle keeps updating Java). ; in the end enables assignment of multiple values to PATH variable.
6. Click OK! Done

To be sure that everything works, open CMD Prompt and type: java -version to check for Java version and javac to be sure that compiler responds.

I hope this helps. Good luck!

Something to be aware of, the $_SESSION variables are still set in the same page after calling session_destroy() where as this is not the case when using unset($_SESSION) or $_SESSION = array(). Also, unset($_SESSION) blows away the $_SESSION superglobal so only do this when you're destroying a session.

With all that said, it's best to do like the PHP docs has it in the first example for session_destroy().

The features available to use are dependent on your processor. Apple uses the same Intel stuff as everybody else. So yes, generic x86 should be fine (assuming you're not on a PPC :D).

As far as tools go, I think your best bet is a good text editor that 'understands' assembly.

first call the intent

Intent intenta = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intenta, 42);

then call the result

    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case 42:

            break;
    }
}

You can use ngClass to apply the class name both conditionally and not in Angular

For Example

[ngClass]="'someClass'">

Conditional

[ngClass]="{'someClass': property1.isValid}">

Multiple Condition

 [ngClass]="{'someClass': property1.isValid && property2.isValid}">

Method expression

[ngClass]="getSomeClass()"

This method will inside of your component

 getSomeClass(){
        const isValid=this.property1 && this.property2;
        return {someClass1:isValid , someClass2:isValid};
    }

That will return an item. Simply change to:

if (ddlCustomerNumber.Items.FindByText( GetCustomerNumberCookie().ToString()) != null)
    ddlCustomerNumber.SelectedIndex = 0;

I had a similar issue where I was not able to either install a CRX file into Chrome.

It turns out that since I had my Downloads folder set to a network mapped drive, it would not allow Chrome to install any extensions and would either do nothing (drag and drop on Chrome) or ask me to download the extension (if I clicked a link from the Web Store).

Setting the Downloads folder to a local disk directory instead of a network directory allowed extensions to be installed.

If if doesn't work then use "!Important"

@media (min-width: 1200px) { .container { width: 970px !important; } }

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

You can merge interface with namespace using the same name:

interface myInterface { }

namespace myInterface {
  Name:string;
}

But this interface is only useful to know that its have property Name. You can not implement it.

Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

select * from tab
where DateCol between adddate(now(),-7) and now() 

Simply use this:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*.*", SearchOption.AllDirectories).ToList();
}

And if you want every file, even extensionless ones:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*", SearchOption.AllDirectories).ToList();
}

I ended up figuring out a (pretty good) solution for this problem!

You can use a TransitionDrawable to accomplish this. For example, in an XML file in the drawable folder you could write something like:

<?xml version="1.0" encoding="UTF-8"?>
<transition xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- The drawables used here can be solid colors, gradients, shapes, images, etc. -->
    <item android:drawable="@drawable/original_state" />
    <item android:drawable="@drawable/new_state" />
</transition>

Then, in your XML for the actual View you would reference this TransitionDrawable in the android:background attribute.

At this point you can initiate the transition in your code on-command by doing:

TransitionDrawable transition = (TransitionDrawable) viewObj.getBackground();
transition.startTransition(transitionTime);

Or run the transition in reverse by calling:

transition.reverseTransition(transitionTime);

To check whether your php.ini file takes effect, open a plain text editor and create a file called phpinfo.php. Insert the following line:

<?php phpinfo(); ?>

Save this file to the root of your Web site and then browse to yourdomain.com/phpinfo.php to test the settings.

How to add 1 year to a date and then subtract 1 day from it in asp.net c#

Convert.ToDateTime(txtDate.Value.Trim()).AddYears(1).AddDays(-1);

For all browsers

The following function will perform a lot faster than the option suggested in the accepted answer:

var repeat = function(str, count) {
    var array = [];
    for(var i = 0; i < count;)
        array[i++] = str;
    return array.join('');
}

You'd use it like this :

var repeatedString = repeat("a", 10);

To compare the performance of this function with that of the option proposed in the accepted answer, see this Fiddle and this Fiddle for benchmarks.

For moderns browsers only

In modern browsers, you can now do this using String.prototype.repeat method:

var repeatedString = "a".repeat(10);

Read more about this method on MDN.

This option is even faster. Unfortunately, it doesn't work in any version of Internet explorer. The numbers in the table specify the first browser version that fully supports the method:

What helped me was that I changed the order. The .eot get's loaded first, but my error was on loading the .eot. So I ditched the .eot as a first src for woff2 and the error went away.

So code is now:

@font-face {
  font-family: 'icomoon';
  src:  url('assets/fonts/icomoon.woff2?9h1pxj') format('woff2');
  src:  url('assets/fonts/icomoon.eot?9h1pxj#iefix') format('embedded-opentype'),
    url('assets/fonts/icomoon.woff2?9h1pxj') format('woff2'),
    url('assets/fonts/icomoon.ttf?9h1pxj') format('truetype'),
    url('assets/fonts/icomoon.woff?9h1pxj') format('woff'),
    url('assets/fonts/icomoon.svg?9h1pxj#icomoon') format('svg');
  font-weight: normal;
  font-style: normal;
  font-display: block;
}

And is was:

@font-face {
  font-family: 'icomoon';
  src:  url('assets/fonts/icomoon.eot?9h1pxj');
  src:  url('assets/fonts/icomoon.eot?9h1pxj#iefix') format('embedded-opentype'),
    url('assets/fonts/icomoon.woff2?9h1pxj') format('woff2'),
    url('assets/fonts/icomoon.ttf?9h1pxj') format('truetype'),
    url('assets/fonts/icomoon.woff?9h1pxj') format('woff'),
    url('assets/fonts/icomoon.svg?9h1pxj#icomoon') format('svg');
  font-weight: normal;
  font-style: normal;
  font-display: block;
}

I know it's silly, but in my case I just tried with sudo and it worked like a charm.

in your case, just try: $ sudo docker-compose up

Yes you can use ALTER TABLE as follows:

ALTER TABLE [table name] ALTER COLUMN [column name] [data type] NULL

Quoting from the ALTER TABLE documentation:

NULL can be specified in ALTER COLUMN to force a NOT NULL column to allow null values, except for columns in PRIMARY KEY constraints.

The best way to find out the REAL type of an object (including BOTH the native Object or DataType name (such as String, Date, Number, ..etc) AND the REAL type of an object (even custom ones); is by grabbing the name property of the object prototype's constructor:

Native Type Ex1:

var string1 = "Test";
console.log(string1.__proto__.constructor.name);

displays:

String

Ex2:

var array1 = [];
console.log(array1.__proto__.constructor.name);

displays:

Array

Custom Classes:

function CustomClass(){_x000D_
  console.log("Custom Class Object Created!");_x000D_
}_x000D_
var custom1 = new CustomClass();_x000D_
_x000D_
console.log(custom1.__proto__.constructor.name);

displays:

CustomClass

Much more convenient way if you are sure you need a default timezone :

Date d = java.sql.Timestamp.valueOf( myLocalDateTime );

Check your servers error log, typically /var/log/apache2/error.log.

Yes, there is one here: http://en.wikipedia.org/wiki/Byte_order_mark#Representations_of_byte_order_marks_by_encoding.

I just wanted to leave the following which enhances the accepted answer above.

In addition to the accepted answer, you can make your own life a bit easier by specifying an alias path in Webpack, so you don't have to worry where the image is located relative to the file you're currently in. Please see example below:

Webpack file:

module.exports = {
  resolve: {
    modules: ['node_modules'],
    alias: {
      public: path.join(__dirname, './public')
    }
  },
}

Use:

<img src={require("public/img/resto.ong")} />

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

You can use the following code to do custom ORDERED serialization and deserialization of JSON Array (This example assumes you are ordering Strings but can be applied to all types):

Serialization

JSONArray params = new JSONArray();
int paramIndex = 0;

for (String currParam : mParams)
{
    JSONObject paramObject = new JSONObject();
    paramObject.put("index", paramIndex);
    paramObject.put("value", currParam);

    params.put(paramObject);
    ++paramIndex;
}

json.put("orderedArray", params);

Deserialization

JSONArray paramsJsonArray = json.optJSONArray("orderedArray");
if (null != paramsJsonArray)
{
    ArrayList<String> paramsArr = new ArrayList<>();
    for (int i = 0; i < paramsJsonArray.length(); i++)
    {
        JSONObject param = paramsJsonArray.optJSONObject(i);
        if (null != param)
        {
            int paramIndex = param.optInt("index", -1);
            String paramValue = param.optString("value", null);

            if (paramIndex > -1 && null != paramValue)
            {
                paramsArr.add(paramIndex, paramValue);
            }
        }
    }
}

Have you tried resetting the image containers html. Of course if it's the browser that is caching then this wouldn't help.

function imageUploadComplete () {
    $("#image_container").html("<img src='" + newImageUrl + "'>");
}

There are a few ways to get all unique combinations of a set of factors.

with(df, interaction(yad, per, drop=TRUE))   # gives labels
with(df, yad:per)                            # ditto

aggregate(numeric(nrow(df)), df[c("yad", "per")], length)    # gives a data frame

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

You can use either resample or Grouper (which resamples under the hood).

First make sure that the datetime column is actually of datetimes (hit it with pd.to_datetime). It's easier if it's a DatetimeIndex:

In [11]: df1
Out[11]:
            abc  xyz
Date
2013-06-01  100  200
2013-06-03  -20   50
2013-08-15   40   -5
2014-01-20   25   15
2014-02-21   60   80

In [12]: g = df1.groupby(pd.Grouper(freq="M"))  # DataFrameGroupBy (grouped by Month)

In [13]: g.sum()
Out[13]:
            abc  xyz
Date
2013-06-30   80  250
2013-07-31  NaN  NaN
2013-08-31   40   -5
2013-09-30  NaN  NaN
2013-10-31  NaN  NaN
2013-11-30  NaN  NaN
2013-12-31  NaN  NaN
2014-01-31   25   15
2014-02-28   60   80

In [14]: df1.resample("M", how='sum')  # the same
Out[14]:
            abc  xyz
Date
2013-06-30   40  125
2013-07-31  NaN  NaN
2013-08-31   40   -5
2013-09-30  NaN  NaN
2013-10-31  NaN  NaN
2013-11-30  NaN  NaN
2013-12-31  NaN  NaN
2014-01-31   25   15
2014-02-28   60   80

Note: Previously pd.Grouper(freq="M") was written as pd.TimeGrouper("M"). The latter is now deprecated since 0.21.

I had thought the following would work, but it doesn't (due to as_index not being respected? I'm not sure.). I'm including this for interest's sake.

If it's a column (it has to be a datetime64 column! as I say, hit it with to_datetime), you can use the PeriodIndex:

In [21]: df
Out[21]:
        Date  abc  xyz
0 2013-06-01  100  200
1 2013-06-03  -20   50
2 2013-08-15   40   -5
3 2014-01-20   25   15
4 2014-02-21   60   80

In [22]: pd.DatetimeIndex(df.Date).to_period("M")  # old way
Out[22]:
<class 'pandas.tseries.period.PeriodIndex'>
[2013-06, ..., 2014-02]
Length: 5, Freq: M

In [23]: per = df.Date.dt.to_period("M")  # new way to get the same

In [24]: g = df.groupby(per)

In [25]: g.sum()  # dang not quite what we want (doesn't fill in the gaps)
Out[25]:
         abc  xyz
2013-06   80  250
2013-08   40   -5
2014-01   25   15
2014-02   60   80

To get the desired result we have to reindex...

In your gem file Uncomment this line.

19 # gem 'therubyracer', platforms: :ruby

And run bundle install

You are ready to work. :)

There is a nice way of doing conditional INSERT in PostgreSQL using WITH query: Like:

WITH a as(
select 
 id 
from 
 schema.table_name 
where 
 column_name = your_identical_column_value
)
INSERT into 
 schema.table_name
(col_name1, col_name2)
SELECT
    (col_name1, col_name2)
WHERE NOT EXISTS (
     SELECT
         id
     FROM
         a
        )
  RETURNING id 

I used some of the answers and found one that fit my case ( make sure all tasks are in the release branch).

Other methods works as well but I found that they might add lines that I do not need, like merge commits that add no value.

git fetch
git log origin/master..origin/release-1.1 --oneline --no-merges

or you can compare your current with master

git fetch
git log origin/master..HEAD --oneline --no-merges

git fetch is there to make sure you are using updated info.

In this way each commit will be on a line and you can copy/paste that into an text editor and start comparing the tasks with the commits that will be merged.

This idea can apply?. If you use CountdownLatches or Semaphores works perfect but if u are looking for the easiest answer for an interview i think this can apply.

On declaration you can do the following.

float[] values = {0.1f, 0.2f, 0.3f};

When the field is already defined, try this.

values = new float[] {0.1f, 0.2f, 0.3f};

Be aware that also the second version creates a new array. If values was the only reference to an already existing field, it becomes eligible for garbage collection.

As bellow we can remove table rows with specific row id

<html>
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script>
<script type="text/javascript">
function remove(id)
{
$('table#test tr#'+id).remove();
// or you can use bellow line also
//$('#test tr#'+id).remove();
}
</script>
    </head>
<body>
<table id="test">
 <tr id="1"><td>bla</td><td><input type="button" onclick="remove(1)"value="Remove"></td></tr>
 <tr id="2"><td>bla</td><td><input type="button" onclick="remove(2)" value="Remove"></td></tr>
 <tr id="3"><td>bla</td><td><input type="button" onclick="remove(3)" value="Remove"></td></tr>
 <tr id="4"><td>bla</td><td><input type="button" onclick="remove(4)" value="Remove"></td></tr>
</table>
</body></html>

Use below regular expression

^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+)+((\.)[a-z]{2,})+$

Here's the proper way to do things:

<?PHP
$sql = 'some query...';
$result = mysql_query($q);

if (! $result){
   throw new My_Db_Exception('Database error: ' . mysql_error());
}

while($row = mysql_fetch_assoc($result)){
  //handle rows.
}

Note the check on (! $result) -- if your $result is a boolean, it's certainly false, and it means there was a database error, meaning your query was probably bad.

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

it's possible with v2 = Convert.ToInt32(v1);

Discovered that calling stat is slow and collects a lot of info that is not required for file existence check.
After spending some time searching for solution, i discovered following solution, which works much faster:

- raw: test -e /path/to/something && echo true || echo false
  register: file_exists

- debug: msg="Path exists"
  when: file_exists == true

Use this

<script>
$(document).ready(function(){
    $( '.expand' ).click(function() {
        $( '.img_display_content' ).show();
    });
});
</script>

Event assigning always after Document Object Model loaded

You did it the wrong way around. You are meant to reset first, to unstage the file, then checkout, to revert local changes.

Try this:

$ git reset foo/bar.txt
$ git checkout foo/bar.txt

This error is because of multiple project having the offending resources.

Try out adding the dependencies projects other way around. (like in pom.xml or external depandancies)

onSelect doesn't work well in ng-repeat, so I made another version using event bind

html

<tr ng-repeat="product in products">
<td>
    <input type="text" ng-model="product.startDate" class="form-control date-picker" data-date-format="yyyy-mm-dd" datepicker/>
</td>
</tr>

script

angular.module('app', []).directive('datepicker', function () {
    return {

To the very first please run the below commands to install python dependencies otherwise python runserver command will throw error.

sudo apt-get install libmysqlclient-dev
sudo pip install MySQL-python

Then configure the settings.py file as defined by #Andy and at the last execute :

python manage.py runserver

Have fun..!!

Wouldn't you just change:

numero = stmt.executeUpdate(query);

to:

numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);

Take a look at the documentation for the JDBC Statement interface.

Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero variable is completely irrelevant and its value is never read after it is set.

your device older than minSDK , edit minSdkVersion in build.gradle

You may get the following error while creating an optimized production build when using query-string module.

Failed to minify the code from this file: ./node_modules/query-string/index.js:8

To overcome this, kindly use the alternative module called stringquery which does the same process well without any issues while running the build.

import querySearch from "stringquery";

var query = querySearch(this.props.location.search);

You could use cut

 df$valueBin <- cut(df$value, c(-Inf, 250, 500, 1000, 2000, Inf), 
    labels=c('<=250', '250-500', '500-1,000', '1,000-2,000', '>2,000'))

data

 set.seed(24)
 df <- data.frame(value= sample(0:2500, 100, replace=TRUE))

I tried recursively deleting all lock files, but that just resulted the error "Path is not a working copy". I ended up having to do Team->Disconnect and then Team->Share. Upon reconnect, it complained about existing .svn files, which it deleted. Now it seems to be working.

Taken from this answer.

1. Close your packages.config file.
2. Build
3. Warning is gone!

This is the first time I see ignoring a problem actually makes it go away...

Edit in 2020: if you are viewing this warning, consider upgrading to PackageReference if you can

If you go to http://github.com/my_user_name/my_repo you will see a textbox where you can select the git path to your repository. You'll want to use this!

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

Simplest way is:

in script_1.py:

import subprocess
subprocess.call(['python3',<path_to_script_2.py>])

in script_2.py:

sys.argv[0]

P.S.: I've tried execfile, but since it reads script_2.py as a string, sys.argv[0] returned <string>.

Double check if you are not able to use keys.

Otherwise use expect:

#!/usr/bin/expect -f
spawn ssh [email protected]
expect "assword:"
send "mypassword\r"

Make sure Apache didn't get Disabled in Services (Control panel, Admin Tools, Services). If it's Disabled then Set it to Manual and it should run. That was my case, I found Apache Disabled.

Here is working code that defines a subroutine make_3d_array to allocate a multidimensional 3D array with N1, N2 and N3 elements in each dimension, and then populates it with random numbers. You can use the notation A[i][j][k] to access its elements.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


// Method to allocate a 2D array of floats
float*** make_3d_array(int nx, int ny, int nz) {
    float*** arr;
    int i,j;

    arr = (float ***) malloc(nx*sizeof(float**));

    for (i = 0; i < nx; i++) {
        arr[i] = (float **) malloc(ny*sizeof(float*));

        for(j = 0; j < ny; j++) {
            arr[i][j] = (float *) malloc(nz * sizeof(float));
        }
    }

    return arr;
} 



int main(int argc, char *argv[])
{
    int i, j, k;
    size_t N1=10,N2=20,N3=5;

    // allocates 3D array
    float ***ran = make_3d_array(N1, N2, N3);

    // initialize pseudo-random number generator
    srand(time(NULL)); 

    // populates the array with random numbers
    for (i = 0; i < N1; i++){
        for (j=0; j<N2; j++) {
            for (k=0; k<N3; k++) {
                ran[i][j][k] = ((float)rand()/(float)(RAND_MAX));
            }
        }
   }

    // prints values
    for (i=0; i<N1; i++) {
        for (j=0; j<N2; j++) {
            for (k=0; k<N3; k++) {
                printf("A[%d][%d][%d] = %f \n", i,j,k,ran[i][j][k]);
            }
        }
    }

    free(ran);
}

string str = "string ";
List<string> li_str = new List<string>();
    for (int k = 0; k < 100; i++ )
         li_str.Add(str+k.ToString());
string[] arr_str = li_str.ToArray();

A very simple way of doing this is to use your your own custom Settings class.

basename() has a bug when processing Asian characters like Chinese.

I use this:

function get_basename($filename)
{
    return preg_replace('/^.+[\\\\\\/]/', '', $filename);
}

You can use this:

function isDigit(n) {
    return Boolean([true, true, true, true, true, true, true, true, true, true][n]);
}

Here, I compared it to the accepted method: http://jsperf.com/isdigittest/5 . I didn't expect much, so I was pretty suprised, when I found out that accepted method was much slower.

Interesting thing is, that while accepted method is faster correct input (eg. '5') and slower for incorrect (eg. 'a'), my method is exact opposite (fast for incorrect and slower for correct).

Still, in worst case, my method is 2 times faster than accepted solution for correct input and over 5 times faster for incorrect input.

To pipe the result to the response object (scenarios where there is a need to download the zip rather than store locally)

 archive.pipe(res);

Sam's hints for accessing the content of the directory worked for me.

src: ["**/*"]

1. String
2. Varchar

This is my opinion for my database as recommended by my mentor

You want to put code in the master page code behind that inserts HTML into the contents of a page that is using that master page?

I would not search for the control via FindControl as this is a fragile solution that could easily be broken if the name of the control changed.

Your best bet is to declare an event in the master page that any child page could handle. The event could pass the HTML as an EventArg.

There are a bunch of values that can be used to undo CSS rules: initial, unset & revert. More details from the CSS Working Group at W3C:

https://drafts.csswg.org/css-cascade/#defaulting-keywords

As this is 'draft' not all are fully supported, but unset and initial are in most major browsers, revert has less support.

Based on the solution by Jason Bunting, here is what I use now.

The whole thing is for the jQuery tablesorter plug-in: For (nearly correct) sorting of non-English tables with tablesorter plugin it is necessary to make use of a custom textExtraction function.

This one:

• translates the most common accented letters to unaccented ones (the list of supported letters is easily expandable)
• changes dates in German format ('dd.mm.yyyy') to a recognized format ('yyyy-mm-dd')

Be careful to save the JavaScript file in UTF-8 encoding or it won't work.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

You can use it like this:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
}); 

Here's a version using the excellent requests library:

from requests import session

payload = {
    'action': 'login',
    'username': USERNAME,
    'password': PASSWORD
}

with session() as c:
    c.post('http://example.com/login.php', data=payload)
    response = c.get('http://example.com/protected_page.php')
    print(response.headers)
    print(response.text)

I as well as you faced a problem of work angular.copy and angular.expect because they do not copy the object or create the object without adding some dependencies. My solution was this:

  copyFactory = (() ->
    resource = ->
      resource.__super__.constructor.apply this, arguments
      return
    this.extendTo resource
    resource
  ).call(factory)

i personally discovered java.lang.Void very late -- improves code readability in conjunction with generics, e.g. Callable<Void>

awk one-liner:

awk '/abc/,/efg/' [file-with-content]

JSON:-

For POST request using json object it can be configured by selecting

Body -> raw -> application/json

Form Data(For Normal content POST):- multipart/form-data

For normal POST request (using multipart/form-data) it can be configured by selecting

Body -> form-data

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

In Windows 7 and later, this will do the trick for you

• Select the file/files.
• Hold the shift key and then right-click on the selected file/files.
• You will see Copy as Path. Click that.
• Open a Notepad file and paste and you will be good to go.

The menu item Copy as Path is not available in Windows XP.

It's the special table in Oracle. I often use it for calculations or checking system variables. For example:

• Select 2*4 from dual prints out the result of the calculation
• Select sysdate from dual prints the server current date.

If you are using python3, then try this(My OS is Ubuntu 16.04):

sudo apt-get install python3-mysqldb

Changed blak3r his code a bit. In case you have two adapters with the same speed. Sort by MAC, so you always get the same value.

public string GetMacAddress()
{
    const int MIN_MAC_ADDR_LENGTH = 12;
    string macAddress = string.Empty;
    Dictionary<string, long> macPlusSpeed = new Dictionary<string, long>();
    try
    {
        foreach(NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
        {
            System.Diagnostics.Debug.WriteLine("Found MAC Address: " + nic.GetPhysicalAddress() + " Type: " + nic.NetworkInterfaceType);

            string tempMac = nic.GetPhysicalAddress().ToString();

            if(!string.IsNullOrEmpty(tempMac) && tempMac.Length >= MIN_MAC_ADDR_LENGTH)
                macPlusSpeed.Add(tempMac, nic.Speed);
        }

        macAddress = macPlusSpeed.OrderByDescending(row => row.Value).ThenBy(row => row.Key).FirstOrDefault().Key;
    }
    catch{}

    System.Diagnostics.Debug.WriteLine("Fastest MAC address: " + macAddress);

    return macAddress;
}

From SQL Server 2012 you can use a native pagination in order to have semplicity and best performance:

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15#using-offset-and-fetch-to-limit-the-rows-returned

Your query become:

SELECT * FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC;
OFFSET 20 ROWS  
FETCH NEXT 20 ROWS ONLY;  

There is a good blog about this topic: http://www.baeldung.com/jackson-serialize-dates Use @JsonFormat looks the most simple way.

public class Event {
    public String name;

    @JsonFormat
      (shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy hh:mm:ss")
    public Date eventDate;
}

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

I found that this worked perfectly for me:

.jumbotron {
background-image: url(/img/Jumbotron.jpg);
background-size: cover;
height: 100%;}

You can resize your screen and it will always take up 100% of the window.

you can use burp-suite. do follow below procedure.

Configure the Burp Proxy listener

In Burp, go to the “Proxy” tab and then the “Options” tab.In the “Proxy Listeners" section, click the “Add” button.

In the "Binding" tab, in the “Bind to port:” box, enter a port number that is not currently in use, e.g. “8082”.Then select the “All interfaces” option, and click "OK".

Configure your device to use the proxy

In your Android device, go to the“Settings” menu.

If your device is not already connected to the wireless network you are using, then switch the "Wi-Fi" button on, and tap the “Wi-Fi” button to access the "Wi-Fi" menu.

In the "Wi-Fi networks" table, find your network and tap it to bring up the connection menu.

Tap "Connect".If you have configured a password, enter it and continue.

Once you are connected hold down on the network button to bring up the context menu.Tap “Modify network config”.

Ensure that the “Show advanced options” box is ticked.

Change the “Proxy settings” to “Manual” by tapping the button.

Then enter the IP of the computer running Burp into the “Proxy hostname”.Enter the port number configured in the “Proxy Listeners” section earlier, in this example “8082”.Tap "Save".

Test the configuration

In Burp, go to the "Proxy Intercept" tab, and ensure that intercept is “on” (if the button says “Intercept is off" then click it to toggle the interception status).

Open the browser on your Android device and go to an HTTP web page (you can visit an HTTPS web page when you have installed Burp's CA Certificate in your Android device.)

The request should be intercepted in Burp.

jQuery has a toggleClass function:

<button class="switch">Click me</button>

<div class="text-block collapsed pressed">some text</div>

<script>    
    $('.switch').on('click', function(e) {
      $('.text-block').toggleClass("collapsed pressed"); //you can list several class names 
      e.preventDefault();
    });
</script>

Iterate through the entrySet() like so:

public static void printMap(Map mp) {
    Iterator it = mp.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        System.out.println(pair.getKey() + " = " + pair.getValue());
        it.remove(); // avoids a ConcurrentModificationException
    }
}

Read more about Map.

What you're doing is valid for the current session (limited to the terminal that you're working in). You need to persist those changes. Consider adding commands in steps 1-3 above to your ${HOME}/.bashrc.

Only one thing more: when you´re using the "crasis variable assignment" you need to use double cotes too AND you do not need to use the "input" word!:

valInput  = $(`[name="${inputNameHere}"]`).val();

How about the following?

window.location.hash=' '

Please note that am setting the hash to a single space and not an empty string.

Setting the hash to an invalid anchor does not cause a refresh either. Such as,

window.location.hash='invalidtag'

But, I find above solution to be misleading. This seems to indicate that there is an anchor on the given position with the given name although there isn't one. At the same time, using an empty string causes page to move to the top which can be unacceptable at times. Using a space also ensures that whenever the URL is copied and bookmarked and visited again, the page will usually be at the top and the space will be ignored.

And, hey, this is my first answer on StackOverflow. Hope someone finds it useful and it matches the community standards.

You have several options:

Convert it to a JSON string, then parse it in PHP (recommended)

JS

var json_arr = JSON.stringify(arr);

PHP

$arr = json_decode($_POST['arr']);

Or use @Curios's method

Sending an array via FormData.

Not recommended: Serialize the data with, then deserialize in PHP

JS

// Use <#> or any other delimiter you want
var serial_arr = arr.join("<#>"); 

PHP

$arr = explode("<#>", $_POST['arr']);

You can replace the values "null" from the original file & field/column.

When your are trying to apply prod on string type of value like:

['-214' '-153' '-58' ..., '36' '191' '-37']

you will get the error.

Solution: Append only integer value like [1,2,3], and you will get your expected output.

If the value is in string format before appending then, in the array you can convert the type into int type and store it in a list.

height for td works like min-height:

td {
  height: 100px;
}

instead of

td {
  min-height: 100px;
}

Table cells will grow when the content does not fit.

https://jsfiddle.net/qz70zps4/

Use print("use this bracket -sample text")

In Python 3 print "Hello world" gives invalid syntax error.

To display string content in Python3 have to use this ("Hello world") brackets.

l = [1, 2, 3]
print '\n'.join(['%i: %s' % (n, l[n]) for n in xrange(len(l))])

I was facing same problem but accidentlty I sorted this problem. 1) Login in github 2) Click on Fork Button at Top Right. 3) After above step you can see Clone or download in Green color under <> Code Tab.

If you are trying to display an Image in this way inside a loop, then you need to wrap the Image constructor in a display method.

from IPython.display import Image, display

listOfImageNames = ['/path/to/images/1.png',
                    '/path/to/images/2.png']

for imageName in listOfImageNames:
    display(Image(filename=imageName))

            frame[3] = (Byte)(length & 255);
            indexStartRawData = 4;
        }
        else
        {
            frame[1] = (Byte)127;
            frame[2] = (Byte)((length >> 56) & 255);
            frame[3] = (Byte)((length >> 48) & 255);
            frame[4] = (Byte)((length >> 40) & 255);
            frame[5] = (Byte)((length >> 32) & 255);
            frame[6] = (Byte)((length >> 24) & 255);
            frame[7] = (Byte)((length >> 16) & 255);
            frame[8] = (Byte)((length >> 8) & 255);
            frame[9] = (Byte)(length & 255);

            indexStartRawData = 10;
        }

        response = new Byte[indexStartRawData + length];

        Int32 i, reponseIdx = 0;

        //Add the frame bytes to the reponse
        for (i = 0; i < indexStartRawData; i++)
        {
            response[reponseIdx] = frame[i];
            reponseIdx++;
        }

        //Add the data bytes to the response
        for (i = 0; i < length; i++)
        {
            response[reponseIdx] = bytesRaw[i];
            reponseIdx++;
        }

        return response;
    }

Use String.matches(), like:

String myString = "qwerty123456";
System.out.println(myString.matches("[A-Za-z0-9]+"));

That may not be the absolute "fastest" possible approach. But in general there's not much point in trying to compete with the people who write the language's "standard library" in terms of performance.

For the CTRL+C case, you can use this:

// Tell the system console to handle CTRL+C by calling our method that
// gracefully shuts down.
Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);


static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
            Console.WriteLine("Shutting down...");
            // Cleanup here
            System.Threading.Thread.Sleep(750);
}

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

For Asp.net Core 2

ViewContext.ModelState["id"].AttemptedValue

This method orderBy does not change the input array, you have to assign the result to your array :

var chars = this.state.characters;

chars = _.orderBy(chars, ['name'],['asc']); // Use Lodash to sort array by 'name'

 this.setState({characters: chars})

Just right click on your project and then go to

*Export -> Android -> Export Android Application -> YOUR_PROJECT_NAME -> Create new key store path -> Fill the detail -> Set the .apk location -> Now you can get your .apk file*

Sometimes your build folder simply needs cleaning - it certainly worked for me. Thanks to loafer-project for the solution.

I'm adding my own answer just because everyone else has covered the hoisting part thoroughly.

I've wondered about which way is better for a long while now, and thanks to http://jsperf.com now I know :)

Function declarations are faster, and that's what really matters in web dev right? ;)

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner:

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

Then to show again:

myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

... and to show:

myDiv.show();

I was having this problem but i found out that it was a permissions problem I changed my permissions to 0744 and now it works. I don't know if this was your problem but it worked for me.

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

buf.erase(buf.size() - 1);

This assumes you know that the string is not empty. If so, you'll get an out_of_range exception.

Java does not allow abstract variables and/or constructor definitions in interfaces. Solution: Simply hang an abstract class between your interface and your implementation which only extends the abstract class like so:

 public interface IMyClass {

     void methodA();
     String methodB();
     Integer methodC();

 }

 public abstract class myAbstractClass implements IMyClass {
     protected String varA, varB;

     //Constructor
     myAbstractClass(String varA, String varB) {
         this.varA = varA;
         this.varB = VarB;
     }

     //Implement (some) interface methods here or leave them for the concrete class
     protected void methodA() {
         //Do something
     }

     //Add additional methods here which must be implemented in the concrete class
     protected abstract Long methodD();

     //Write some completely new methods which can be used by all subclasses
     protected Float methodE() {
         return 42.0;
     }

 }

 public class myConcreteClass extends myAbstractClass {

     //Constructor must now be implemented!
     myClass(String varA, String varB) {
         super(varA, varB);
     }

     //All non-private variables from the abstract class are available here
     //All methods not implemented in the abstract class must be implemented here

 }

You can also use an abstract class without any interface if you are SURE that you don't want to implement it along with other interfaces later. Please note that you can't create an instance of an abstract class you MUST extend it first.

(The "protected" keyword means that only extended classes can access these methods and variables.)

A flow chart details the processes to follow. A DFD details the flow of data through a system.

In a flow chart, the arrows represent transfer of control (not data) between elements and the elements are instructions or decision (or I/O, etc).

In a DFD, the arrows are actually data transfer between the elements, which are themselves parts of a system.

Wikipedia has a good article on DFDs here.

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

From EL 2.2 specification (get the one below "Click here to download the spec for evaluation"):

1.10 Empty Operator - empty A

The empty operator is a prefix operator that can be used to determine if a value is null or empty.

To evaluate empty A

• If A is null, return true
• Otherwise, if A is the empty string, then return true
• Otherwise, if A is an empty array, then return true
• Otherwise, if A is an empty Map, return true
• Otherwise, if A is an empty Collection, return true
• Otherwise return false

So, considering the interfaces, it works on Collection and Map only. In your case, I think Collection is the best option. Or, if it's a Javabean-like object, then Map. Either way, under the covers, the isEmpty() method is used for the actual check. On interface methods which you can't or don't want to implement, you could throw UnsupportedOperationException.

You could create your own .xml animation files to fade in a new Activity and fade out the current Activity:

fade_in.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="0.0" android:toAlpha="1.0"
           android:duration="500" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="1.0" android:toAlpha="0.0"
           android:fillAfter="true"
           android:duration="500" />

Use it in code like that: (Inside your Activity)

Intent i = new Intent(this, NewlyStartedActivity.class);
startActivity(i);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);

The above code will fade out the currently active Activity and fade in the newly started Activity resulting in a smooth transition.

UPDATE: @Dan J pointed out that using the built in Android animations improves performance, which I indeed found to be the case after doing some testing. If you prefer working with the built in animations, use:

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

Notice me referencing android.R instead of R to access the resource id.

UPDATE: It is now common practice to perform transitions using the Transition class introduced in API level 19.

In Python 3.5+, encode the string to bytes and use the hex() method, returning a string.

s = "hello".encode("utf-8").hex()
s
# '68656c6c6f'

Optionally convert the string back to bytes:

b = bytes(s, "utf-8")
b
# b'68656c6c6f'

Update 2020: I have a new answer that replaces this, now 8-years-old, one: https://stackoverflow.com/a/61177330/278976

On Linux, I tried cpp-netlib, libcurl, curlpp, urdl, boost::asio and considered Qt (but turned it down based on the license). All of these were either incomplete for this use, had sloppy interfaces, had poor documentation, were unmaintained or didn't support https.

Then, at the suggestion of https://stackoverflow.com/a/1012577/278976, I tried POCO. Wow, I wish I had seen this years ago. Here's an example of making an HTTP GET request with POCO:

https://stackoverflow.com/a/26026828/2817595

POCO is free, open source (boost license). And no, I don't have any affiliation with the company; I just really like their interfaces. Great job guys (and gals).

Hope this helps someone... it took me three days to try all of these libraries out.

After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.

After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here

sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7

And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.

install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)

You can declare a dictionary inside a dictionary by nesting the {} containers:

d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}

And then you can access the elements using the [] syntax:

print d['dict1']           # {'foo': 1, 'bar': 2}
print d['dict1']['foo']    # 1
print d['dict2']['quux']   # 4

Given the above, if you want to add another dictionary to the dictionary, it can be done like so:

d['dict3'] = {'spam': 5, 'ham': 6}

or if you prefer to add items to the internal dictionary one by one:

d['dict4'] = {}
d['dict4']['king'] = 7
d['dict4']['queen'] = 8

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

I was trying to use @class "Myclass.h".

When I changed it to #import "Myclass.h", it worked fine.

Be sure to checkout the branch you want to merge first and then pull it (so your local version matches the remote version).

Then checkout back to your branch you want to do the merge on and your git merge should work.

In View:

<Button
 Height="50" Width="50"
 Style="{StaticResource MyButtonStyle}"
 Command="{Binding SmallDisp}" CommandParameter="{Binding}" 
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat}"/>

In view Model:

public _advancedFormat = Visibility.visible (whatever you start with)

public Visibility AdvancedFormat
{
 get{return _advancedFormat;}
 set{
   _advancedFormat = value;
   //raise property changed here
}

You will need to have a property changed event

 protected virtual void OnPropertyChanged(PropertyChangedEventArgs e) 
    { 
        PropertyChanged.Raise(this, e); 
    } 

    protected void OnPropertyChanged(string propertyName) 
    { 
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName)); 
    } 

This is how they use Model-view-viewmodel

But since you want it binded to a boolean, You will need some converter. Another way is to set a boolean outside and when that button is clicked then set the property_advancedFormat to your desired visibility.

It's not possible to use an array like that in PDO.

You need to build a string with a parameter (or use ?) for each value, for instance:

:an_array_0, :an_array_1, :an_array_2, :an_array_3, :an_array_4, :an_array_5

Here's an example:

<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = join(
    ', ',
    array_map(
        function($index) {
            return ":an_array_$index";
        },
        array_keys($ids)
    )
);
$db = new PDO(
    'mysql:dbname=mydb;host=localhost',
    'user',
    'passwd'
);
$stmt = $db->prepare(
    'SELECT *
     FROM table
     WHERE id IN('.$sqlAnArray.')'
);
foreach ($ids as $index => $id) {
    $stmt->bindValue("an_array_$index", $id);
}

If you want to keep using bindParam, you may do this instead:

foreach ($ids as $index => $id) {
    $stmt->bindParam("an_array_$index", $ids[$id]);
}

If you want to use ? placeholders, you may do it like this:

<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = '?' . str_repeat(', ?', count($ids)-1);
$db = new PDO(
    'mysql:dbname=dbname;host=localhost',
    'user',
    'passwd'
);
$stmt = $db->prepare(
    'SELECT *
     FROM phone_number_lookup
     WHERE country_code IN('.$sqlAnArray.')'
);
$stmt->execute($ids);

If you don't know if $ids is empty, you should test it and handle that case accordingly (return an empty array, or return a Null Object, or throw an exception, ...).

The syntax:

   ALTER TABLE `table1` CHANGE `itemId` `itemId` INT( 11 ) NOT NULL AUTO_INCREMENT 

But the table needs a defined key (ex primary key on itemId).

In addition to the published answers I can say that a metaclass defines the behaviour for a class. So, you can explicitly set your metaclass. Whenever Python gets a keyword class then it starts searching for the metaclass. If it's not found – the default metaclass type is used to create the class's object. Using the __metaclass__ attribute, you can set metaclass of your class:

class MyClass:
   __metaclass__ = type
   # write here other method
   # write here one more method

print(MyClass.__metaclass__)

It'll produce the output like this:

class 'type'

And, of course, you can create your own metaclass to define the behaviour of any class that are created using your class.

For doing that, your default metaclass type class must be inherited as this is the main metaclass:

class MyMetaClass(type):
   __metaclass__ = type
   # you can write here any behaviour you want

class MyTestClass:
   __metaclass__ = MyMetaClass

Obj = MyTestClass()
print(Obj.__metaclass__)
print(MyMetaClass.__metaclass__)

The output will be:

class '__main__.MyMetaClass'
class 'type'

bash your_script.sh 1>file.log 2>&1

1>file.log instructs the shell to send STDOUT to the file file.log, and 2>&1 tells it to redirect STDERR (file descriptor 2) to STDOUT (file descriptor 1).

Note: The order matters as liw.fi pointed out, 2>&1 1>file.log doesn't work.

In my case, I was getting this error because I had an input named x and I was creating (without realizing it) a local variable called x. I thought I was trying to access an element of the input x (which was an array), while I was actually trying to access an element of the local variable x (which was a scalar).

To get the job done, use

If you’d rather “be right” than get things done, you can instead use the CSS property border-spacing, which is supported by some browsers.

Traditional relational databases were designed as client/server database systems. They can be scaled horizontally but the process to do so tends to be complex and error prone. NewSQL databases like NuoDB are memory-centric distributed database systems designed to scale out horizontally while maintaining the SQL/ACID properties of traditional RDBMS.

For more information on NuoDB, read their technical white paper.

Decoding a filename from the header is a little bit more complex...

    var filename = "default.pdf";
    var disposition = req.getResponseHeader('Content-Disposition');

    if (disposition && disposition.indexOf('attachment') !== -1) 
    {
       var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
       var matches = filenameRegex.exec(disposition);

       if (matches != null && matches[1]) 
           filename = matches[1].replace(/['"]/g, '');
    }

InputProperty[] ip = new InputProperty[nvPairs.Length]; 

Or, you can use a list like so:

List<InputProperty> list = new List<InputProperty>();
InputProperty ip = new (..);
list.Add(ip);
update.items = list.ToArray();

Another thing I'd like to point out, in C# you can delcare your int variable use in a for loop right inside the loop:

for(int i = 0; i<nvPairs.Length;i++
{
.
.
}

And just because I'm in the mood, here's a cleaner way to do this method IMO:

private Update BuildMetaData(MetaData[] nvPairs)
{
        Update update = new Update();
        var ip = new List<InputProperty>();

        foreach(var nvPair in nvPairs)
        {
            if (nvPair == null) break;
            var inputProp = new InputProperty
            {
               Name = "udf:" + nvPair.Name,
               Val = nvPair.Value
            };
            ip.Add(inputProp);
        }
        update.Items = ip.ToArray();
        return update;
}

There are services available which allow you to artificially create origin timeouts by calling an API where you specify how long the server will take to respond. Server Timeout on macgyver is an example of such a service.

For example if you wanted to test a request that takes 15 seconds to respond you would simply make a post request to the macgyver API.

JSON Payload:

{
    "timeout_length": 15000
}

API Response (After 15 seconds):

{
    "response": "ok"
}

The other answers here provide the bits in big-endian order ('\x01' becomes '00000001')

In case you're interested in little-endian order of bits, which is useful in many cases, like common representations of bignums etc - here's a snippet for that:

def bits_little_endian_from_bytes(s):
    return ''.join(bin(ord(x))[2:].rjust(8,'0')[::-1] for x in s)

And for the other direction:

def bytes_from_bits_little_endian(s):
    return ''.join(chr(int(s[i:i+8][::-1], 2)) for i in range(0, len(s), 8))

So here's what I did eventually. I hope this helps someone else.

class NoDuplicatesList<E> extends LinkedList<E> {
    @Override
    public boolean add(E e) {
        if (this.contains(e)) {
            return false;
        }
        else {
            return super.add(e);
        }
    }

    @Override
    public boolean addAll(Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(copy);
    }

    @Override
    public boolean addAll(int index, Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(index, copy);
    }

    @Override
    public void add(int index, E element) {
        if (this.contains(element)) {
            return;
        }
        else {
            super.add(index, element);
        }
    }
}   

You can easily do this with the normal "Time" data type - just change the format!

Excels time/date format is simply 1.0 equals 1 full day (starting on 1/1/1900). So 36 hours would be 1.5. If you change the format to [h]:mm, you'll see 36:00.

Therefore, if you want to work with durations, you can simply use subtraction, e.g.

A1: Start:           36:00 (=1.5)
A2: End:             60:00 (=2.5) 
A3: Duration: =A2-A1 24:00 (=1.0)

Is there a reason you are not doing something like:

public class IPGUI extends JFrame implements ActionListener 
{
    private static JPanel contentPane;

    private JButton btnConvertDocuments;
    private JButton btnExtractImages;
    private JButton btnParseRIDValues;
    private JButton btnParseImageInfo;

    public IPGUI() 
    {

The if statement with your disabling code won't get called unless you keep calling the IPGUI constructor.

You can set imageview in XML file like this :

<ImageView
    android:id="@+id/image1"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:src="@drawable/imagep1" />

and you can define image view in android java file like :

ImageView imageView = (ImageView) findViewById(R.id.imageViewId);

and set Image with drawable like :

imageView.setImageResource(R.drawable.imageFileId);

and set image with your memory folder like :

File file = new File(SupportedClass.getString("pbg"));
if (file.exists()) {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap selectDrawable = BitmapFactory.decodeFile(file.getAbsolutePath(), options);
        imageView.setImageBitmap(selectDrawable);
}
else
{
      Toast.makeText(getApplicationContext(), "File not Exist", Toast.LENGTH_SHORT).show();
}

LinearLayout YOUR_LinearLayout =(LinearLayout)findViewById(R.id.YOUR_LinearLayout)
    LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
                       /*width*/ ViewGroup.LayoutParams.MATCH_PARENT,
               /*height*/ 100,
               /*weight*/ 1.0f
                );
                YOUR_LinearLayout.setLayoutParams(param);

Less than Tera will write on GB & more than 999 GB write on TB

[<1000]0" GB";[>999]0.0," TB"

OR

[<1000]0" GB";[>=1000]0.0," TB"

Now you should be able to do it directly in the IB.

Not sure though, if this was available when the question was posted originally.

This is one way.

Map<String, String> h = new HashMap<String, String>() {{
    put("a","b");
}};

However, you should be careful and make sure that you understand the above code (it creates a new class that inherits from HashMap). Therefore, you should read more here: http://www.c2.com/cgi/wiki?DoubleBraceInitialization , or simply use Guava:

Map<String, Integer> left = ImmutableMap.of("a", 1, "b", 2, "c", 3);

ImmutableMap.of works for up to 5 entries. Otherwise, use the builder: source.

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

You are most likely pushing a string 'NULL' to the table, rather then an actual NULL, but other things may be going on as well, an illustration:

mysql> CREATE TABLE date_test (pdd DATE NOT NULL);

mysql> INSERT INTO date_test VALUES (NULL);
ERROR 1048 (23000): Column 'pdd' cannot be null
mysql> INSERT INTO date_test VALUES ('NULL');
