It is very simple to make a variable global in a class:

a = 0

class b():
    global a
    a = 10

>>> a
10

Assuming you are using this plugin, you are misusing the .set method. .set must be passed the name of the key as a string as well as the value. I suppose you meant to write:

$.session.set("userName", $("#uname").val());

This sets the userName key in session storage to the value of the input, and allows you to retrieve it using:

$.session.get('userName');

Be careful if you have to deal with large numbers.

int[] arr = new int[]{Integer.MIN_VALUE, Integer.MIN_VALUE};
long sum = Arrays.stream(arr).sum(); // Wrong: sum == 0

The sum above is not 2 * Integer.MIN_VALUE. You need to do this in this case.

long sum = Arrays.stream(arr).mapToLong(Long::valueOf).sum(); // Correct

In Java-8 you can use IntStream to produce a stream of numbers that you want to repeat, and then convert it to array. This approach produces an expression suitable for use in an initializer:

int[] data = IntStream.generate(() -> value).limit(size).toArray();

Above, size and value are expressions that produce the number of items that you want tot repeat and the value being repeated.

Demo.

Well, after seven years you can change whole app textView or what you want easily by using android.support libraries 26++.

E.g:

Create your font package app/src/res/font and move your font into it.

And in your app theme just add it as a fontFamily:

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
   . . . ...
    <item name="android:fontFamily">@font/demo</item>
</style>

Example for use with textView only:

<style name="fontTextView" parent="@android:style/Widget.TextView">
    <item name="android:fontFamily">monospace</item>
</style>

And add into your main theme:

<item name="android:textViewStyle">@style/fontTextView</item>

Currently it's worked on 8.1 until 4.1 API Jelly Bean And that's a wide range.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

Access modifiers

From docs.microsoft.com:

public

The type or member can be accessed by any other code in the same assembly or another assembly that references it.

private

The type or member can only be accessed by code in the same class or struct.

protected

The type or member can only be accessed by code in the same class or struct, or in a derived class.

private protected (added in C# 7.2)

The type or member can only be accessed by code in the same class or struct, or in a derived class from the same assembly, but not from another assembly.

internal

The type or member can be accessed by any code in the same assembly, but not from another assembly.

protected internal

The type or member can be accessed by any code in the same assembly, or by any derived class in another assembly.

When no access modifier is set, a default access modifier is used. So there is always some form of access modifier even if it's not set.

static modifier

The static modifier on a class means that the class cannot be instantiated, and that all of its members are static. A static member has one version regardless of how many instances of its enclosing type are created.

A static class is basically the same as a non-static class, but there is one difference: a static class cannot be externally instantiated. In other words, you cannot use the new keyword to create a variable of the class type. Because there is no instance variable, you access the members of a static class by using the class name itself.

However, there is a such thing as a static constructor. Any class can have one of these, including static classes. They cannot be called directly & cannot have parameters (other than any type parameters on the class itself). A static constructor is called automatically to initialize the class before the first instance is created or any static members are referenced. Looks like this:

static class Foo()
{
    static Foo()
    {
        Bar = "fubar";
    }
    
    public static string Bar { get; set; }
}

Static classes are often used as services, you can use them like so:

MyStaticClass.ServiceMethod(...);

This should do it. Be sure to set your bullets to the outside. you can also use CSS pseudo elements if you can drop them in IE7 downward. I don't really recommend using pseudo elements for this kinda thing but it does work to control distance.

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

use a trigges it will work:-

->CREATE TRIGGER trigger_name BEFORE INSERT ON table_name

FOR EACH ROW SET NEW.column_name3 = NEW.column_name1 + NEW.column_name2;

this will only work only when you will insert a row in table not when you will be updating your table for such a pupose create another trigger of different name and use UPDATE on the place of INSERT in the above syntax

Just replace -H with -h. Check man grep for more details on options

find . -name '*.bar' -exec grep -hn FOO {} \;

The answers provided by Bohzo and Brabster will obviously work, but you could also just use:

rs3.getInt(1);

to get the value in the first, and in your case, only column.

Here is another simpler take:

df = pd.DataFrame([[0,1,3,4,np.nan,2],[3,5,6,np.nan,3,3]])

inds = np.asarray(df.isnull()).nonzero()

(array([0, 1], dtype=int64), array([4, 3], dtype=int64))

You can use pip install scikit-image.

Also see the recommended procedure.

The first thing is to understand that, the Dispatcher is not designed to run long blocking operation (such as retrieving data from a WebServer...). You can use the Dispatcher when you want to run an operation that will be executed on the UI thread (such as updating the value of a progress bar).

What you can do is to retrieve your data in a background worker and use the ReportProgress method to propagate changes in the UI thread.

If you really need to use the Dispatcher directly, it's pretty simple:

Application.Current.Dispatcher.BeginInvoke(
  DispatcherPriority.Background,
  new Action(() => this.progressBar.Value = 50));

Deleting all files from Gradle cache fixed my problem.

on Linux:

rm -rf ~/.gradle/caches/*

You use List#get(int index) to get an object with the index index in the list. You use it like that:

List<ExampleClass> list = new ArrayList<ExampleClass>();
list.add(new ExampleClass());
list.add(new ExampleClass());
list.add(new ExampleClass());
ExampleClass exampleObj = list.get(2); // will get the 3rd element in the list (index 2);

Alternately,

You can use your own Application class and call from wherever you needs (especially non-activities).

public class App extends Application {

    protected static Context context = null;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    public static Context getContext() {
        return context;
    }

}

And register your Application class :

<application android:name="yourpackage.App" ...

Then call :

App.getContext();

In that particular example, the error it's because of the GO after the use statements. The GO statements resets the environment, so no user variables exists. They must be declared again. And the answer to the global variables question is No, does not exists global variables at least Sql server versions equal or prior to 2008. I cannot assure the same for newer sql server versions.

Problem: My VS 2015 was throwing up error after I installed SSDT. Whenever I clicked on Tools >> Extensions and Update it was throwing "Object reference not set to an instance of an object" error. When I tried to open a solution it threw some provider not set correctly.

Solution: After many hours of research trying out all the solutions previously mentioned by others didn't solve my problem. Every time the error popup was pointing to check the ActivityLog.xml. But I was ignoring it. After hours of frustration I decided to read the error carefully and looked into ActivitLog.xml and found that it was looking for "Could not load file or assembly 'System.Collections.Immutable, Version=1.1.37.0". So I just started searching for this assembly and stumbled upon this link https://sergeytihon.com/2015/12/01/how-to-restore-viual-studio-2015-after-update-1-dependency-dance/ and followed the steps there, which fixed my issue.

Went into %LOCALAPPDATA%/Local\Microsoft\VisualStudio\14.0\devenv.exe.config and searched for "System.Collections.Immutable" and change newVersion from 1.1.36.0 to 1.1.37.0

Final config should look like this

<dependentAssembly>
 <assemblyIdentity name="System.Collections.Immutable" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
 <bindingRedirect oldVersion="1.0.27.0-1.1.65535.65535" newVersion="1.1.37.0"/>
</dependentAssembly>

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

For either the os.rename or shutil.move you will need to import the module. No * character is necessary to get all the files moved.

We have a folder at /opt/awesome called source with one file named awesome.txt.

in /opt/awesome
? ? ls
source
? ? ls source
awesome.txt

python 
>>> source = '/opt/awesome/source'
>>> destination = '/opt/awesome/destination'
>>> import os
>>> os.rename(source, destination)
>>> os.listdir('/opt/awesome')
['destination']

We used os.listdir to see that the folder name in fact changed. Here's the shutil moving the destination back to source.

>>> import shutil
>>> shutil.move(destination, source)
>>> os.listdir('/opt/awesome/source')
['awesome.txt']

This time I checked inside the source folder to be sure the awesome.txt file I created exists. It is there :)

Now we have moved a folder and its files from a source to a destination and back again.

It looks like you are trying to parse each line. You've been shown by another answer how to use getline in a loop to seperate each line. The other tool you are going to want is istringstream, to seperate each token.

std::string line;
while(std::getline(file, line))
{
    std::istringstream iss(line);
    std::string token;
    while (iss >> token)
    {
        // do something with token
    }
}

Use sudo -i to switch to $root, then execute npm install -g xxxx

you may use this below option.

<style>
  div:not(.no_common_style){
      background-color:red;
  }
</style>

now , if their any place where you do not want to apply default style you can use 'no_common_style' class as class. ex:

<div class="no_common_style">
  It will not display in red
</div>

We can find the the mean of a row using the range function, i.e in your case, from the Y1961 column to the Y1965

df['mean'] = df.iloc[:, 0:4].mean(axis=1)

And if you want to select individual columns

df['mean'] = df.iloc[:, [0,1,2,3,4].mean(axis=1)

Your DOS command 2> nul

Read page Using command redirection operators. Besides the "2>" construct mentioned by Tanuki Software, it lists some other useful combinations.

u'AB' is just a text representation of the corresponding Unicode string. Here're several methods that create exactly the same Unicode string:

L = [u'AB', u'\x41\x42', u'\u0041\u0042', unichr(65) + unichr(66)]
print u", ".join(L)

Output

AB, AB, AB, AB

There is no u'' in memory. It is just the way to represent the unicode object in Python 2 (how you would write the Unicode string literal in a Python source code). By default print L is equivalent to print "[%s]" % ", ".join(map(repr, L)) i.e., repr() function is called for each list item:

print L
print "[%s]" % ", ".join(map(repr, L))

Output

[u'AB', u'AB', u'AB', u'AB']
[u'AB', u'AB', u'AB', u'AB']

If you are working in a REPL then a customizable sys.displayhook is used that calls repr() on each object by default:

>>> L = [u'AB', u'\x41\x42', u'\u0041\u0042', unichr(65) + unichr(66)]
>>> L
[u'AB', u'AB', u'AB', u'AB']
>>> ", ".join(L)
u'AB, AB, AB, AB'
>>> print ", ".join(L)
AB, AB, AB, AB

Don't encode to bytes. Print unicode directly.

In your specific case, I would create a Python list and use json.dumps() to serialize it instead of using string formatting to create JSON text:

#!/usr/bin/env python2
import json
# ...
test = [dict(email=player.email, gem=player.gem)
        for player in players]
print test
print json.dumps(test)

Output

[{'email': u'[email protected]', 'gem': 0}, {'email': u'test', 'gem': 0}, {'email': u'test', 'gem': 0}, {'email': u'test', 'gem': 0}, {'email': u'test', 'gem': 0}, {'email': u'test1', 'gem': 0}]
[{"email": "[email protected]", "gem": 0}, {"email": "test", "gem": 0}, {"email": "test", "gem": 0}, {"email": "test", "gem": 0}, {"email": "test", "gem": 0}, {"email": "test1", "gem": 0}]

The behaviour comes from the fact that in Python prior to version 3 bytes was just an alias for str. In Python3.x bytes is an immutable version of bytearray - completely new type, not backwards compatible.

If you are looking for optimizing your docker mysql container then the below command may help. I was able to run mysql docker container from a default 480mb to mere 100 mbs

docker run -d -p 3306:3306 -e MYSQL_DATABASE=test -e MYSQL_ROOT_PASSWORD=tooor -e MYSQL_USER=test -e MYSQL_PASSWORD=test -v /mysql:/var/lib/mysql --name mysqldb mysql --table_definition_cache=100 --performance_schema=0 --default-authentication-plugin=mysql_native_password

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Just append an empty string to the end. It forces Excel to see it for what it is.

For example:

=IFERROR(1/1/INDEX(A,B,C) & "","")

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

You can easily set a pandas.DataFrame column to a constant. This constant can be an int such as in your example. If the column you specify isn't in the df, then pandas will create a new column with the name you specify. So after your dataframe is constructed, (from your question):

df = pd.DataFrame({'a':[np.nan, 2, 3], 'b':[4, 5, 6]}, index=[3, 5, 6])

You can just run:

df['s1'], df['s2'] = 5, 6

You could write a loop or comprehension to make it do this for all the elements in a list of tuples, or keys and values in a dictionary depending on how you have your real data stored.

What you're looking for is setattr I believe. Use this to set an attribute on an object.

>>> def printme(s): print repr(s)
>>> class A: pass
>>> setattr(A,'printme',printme)
>>> a = A()
>>> a.printme() # s becomes the implicit 'self' variable
< __ main __ . A instance at 0xABCDEFG>

After using git for a long time without problems, I encountered this problem today. After some reflection, I realized I changed my umask earlier today from 022 to something else.

All the answers by other people are helpful, i.e., do chmod for the offending directories. But the root cause is my new umask which will always cause a new problem down the road whenever a new directory is created under .git/object/. So, the long term solution for me is to change umask back to 022.

Add position: relative to .outside. (https://developer.mozilla.org/en-US/docs/CSS/position)

Elements that are positioned relatively are still considered to be in the normal flow of elements in the document. In contrast, an element that is positioned absolutely is taken out of the flow and thus takes up no space when placing other elements. The absolutely positioned element is positioned relative to nearest positioned ancestor. If a positioned ancestor doesn't exist, the initial container is used.

The "initial container" would be <body>, but adding the above makes .outside positioned.

There is another simple and elegant option:

parameters.OfType<EmailParameterClass>();

This will remove all elements that are not of type EmailParameterClass which will obviously filter out any elements of type null.

Here's a test:

class Test { }
class Program
{
    static void Main(string[] args)
    {
        var list = new List<Test>();
        list.Add(null);
        Console.WriteLine(list.OfType<Test>().Count());// 0
        list.Add(new Test());
        Console.WriteLine(list.OfType<Test>().Count());// 1
        Test test = null;
        list.Add(test);
        Console.WriteLine(list.OfType<Test>().Count());// 1
        Console.ReadKey();
    }
}

IE10 does not support DX filters as IE9 and earlier have done, nor does it support a prefixed version of the greyscale filter.

However, you can use an SVG overlay in IE10 to accomplish the greyscaling. Example:

img.grayscale:hover {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 1 0\'/></filter></svg>#grayscale");
}

svg {
    background:url(http://4.bp.blogspot.com/-IzPWLqY4gJ0/T01CPzNb1KI/AAAAAAAACgA/_8uyj68QhFE/s400/a2cf7051-5952-4b39-aca3-4481976cb242.jpg);
}

(from: http://www.karlhorky.com/2012/06/cross-browser-image-grayscale-with-css.html)

More about the IE10 SVG filter effects: http://blogs.msdn.com/b/ie/archive/2011/10/14/svg-filter-effects-in-ie10.aspx

In such cases, you can convert the values of enum to a List and stream through it. Something like below examples. I would recommend using filter().

Using ForEach:

List<Category> category = Arrays.asList(Category.values());
category.stream().forEach(eachCategory -> {
            if(eachCategory.toString().equals("3")){
                String name = eachCategory.name();
            }
        });

Or, using Filter:

When you want to find with code:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.toString().equals("3")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

When you want to find with name:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.name().equals("Apple")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

Hope it helps! I know this is a very old post, but someone can get help.

What sort of rounding behavior do you want? Do you 2.67 to turn into 3, or 2. If you want to use rounding, try this:

s = '234.67'
i = int(round(float(s)))

Otherwise, just do:

s = '234.67'
i = int(float(s))

To give an example to what Alex said, if you're using Magento, for example, .phtml files are only to be found in the /design area as template files, and contain both HTML and PHP lines. Meanwhile the PHP files are pure code and don't have any lines of HTML in them.

You can use the viewport height, just set the height of your div to height:100vh;, this will set the height of your div to the height of the viewport of the device, furthermore, if you want it to be exactly as your device screen, set the margin and padding to 0.

Plus, It will be a good idea to set the viewport meta tag:

<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0" />

Please Note that this is relatively new and is not supported in IE8-, take a look at the support list before considering this approach (http://caniuse.com/#search=viewport).

Hope this helps.

I do not have a JDK installed on my machine to verify this, but here's something to get you started with

%CLASSPATH%=C:\Program Files\Java\jdk1.6\bin rem or whatever your path is
START %CLASSPATH%\javac Main.java
START %CLASSPATH%\java Main

You can use outline with outline offset

<div class="double-border"></div>
.double-border{
background-color:#ccc;
outline: 1px solid #f00;
outline-offset: 3px;
}

Not sure whether you still have this issue. I had a similar issue and I was able to resolve it simply by unsetting PYTHONPATH

$ unset PYTHONPATH

Request-scoped beans can be autowired with the request object.

private @Autowired HttpServletRequest request;

To extend answers above, you cannot use Guid default value with Guid.Empty as an optional argument in method, indexer or delegate definition, because it will give you compile time error. Use default(Guid) or new Guid() instead.

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Foreign keys work with unique constraints as well as primary keys. From Books Online:

A FOREIGN KEY constraint does not have to be linked only to a PRIMARY KEY constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table

For transactional replication, you need the primary key. From Books Online:

Tables published for transactional replication must have a primary key. If a table is in a transactional replication publication, you cannot disable any indexes that are associated with primary key columns. These indexes are required by replication. To disable an index, you must first drop the table from the publication.

Both answers are for SQL Server 2005.

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

Bulk add new categories to Woo:

Insert category id, name, url key

INSERT INTO wp_terms 
VALUES
  (57, 'Apples', 'fruit-apples', '0'),
  (58, 'Bananas', 'fruit-bananas', '0');

Set the term values as catergories

INSERT INTO wp_term_taxonomy 
VALUES
  (57, 57, 'product_cat', '', 17, 0),
  (58, 58, 'product_cat', '', 17, 0)

17 - is parent category, if there is one

key here is to make sure the wp_term_taxonomy table term_taxonomy_id, term_id are equal to wp_term table's term_id

After doing the steps above go to wordpress admin and save any existing category. This will update the DB to include your bulk added categories

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

IMPORTANT - You might have many Virtual devices in your environment. Ensure if you are changing AVD you repeat the setting again.

DEBUG INFORMATION-

Incase you are experiencing above error you have to 1st verify what is running on port 8081

Quickest way to find that is using the following command in terminal

netstat -aon | findstr 8081

if that shows you something it means the port is blocked. if possible get that port unblocked.

Otherwise, you would need to change the port. The process to do that has already been mentioned in the comment above by Naveen Kumar

react-native run-android --port=9001

Ensure 9001 is not used either :)

You can find the solution here!

Live streaming in HTML5 is possible via the use of Media Source Extensions (MSE) - the relatively new W3C standard: https://www.w3.org/TR/media-source/ MSE is an an extension of HTML5 <video> tag; the javascript on webpage can fetch audio/video segments from the server and push them to MSE for playback. The fetching mechanism can be done via HTTP requests (MPEG-DASH) or via WebSockets. As of September 2016 all major browsers on all devices support MSE. iOS is the only exception.

For high latency (5+ seconds) HTML5 live video streaming you can consider MPEG-DASH implementations by video.js or Wowza streaming engine.

For low latency, near real-time HTML5 live video streaming, take a look at EvoStream media server, Unreal media server, and WebRTC.

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

This is what I did for Installing Anaconda Python 3.6 version and Tensorflow on Window 10 64bit.And It was success!

1. Go to https://www.continuum.io/downloads to download Anaconda Python 3.6 version for Window 64bit.

2. Create a conda environment named tensorflow by invoking the following command:

   C:> conda create -n tensorflow

3. Activate the conda environment by issuing the following command:

   C:> activate tensorflow (tensorflow)C:> # Your prompt should change

4. Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/enter code here download “tensorflow-1.0.1-cp36-cp36m-win_amd64.whl”. (For my case, the file will be located in “C:\Users\Joshua\Downloads” once after downloaded)

5. Install the Tensorflow by using the following command:

   (tensorflow)C:>pip install C:\Users\Joshua\Downloads\ tensorflow-1.0.1-cp36-cp36m-win_amd64.whl

This is what I got after the installing:

6. Validate installation by entering following command in your Python environment:

   import tensorflow as tf hello = tf.constant('Hello, TensorFlow!') sess = tf.Session() print(sess.run(hello))

If the output you got is 'Hello, TensorFlow!',that means you have successfully install your Tensorflow.

use zip

columns = zip(*rows) #transpose rows to columns
print columns[0] #print the first column
#you can also do more with the columns
print columns[1] # or print the second column
columns.append([7,7,7]) #add a new column to the end
backToRows = zip(*columns) # now we are back to rows with a new column
print backToRows

you can also use numpy

a = numpy.array(a)
print a[:,0]

Edit: zip object is not subscriptable. It need to be converted to list to access as list:

column = list(zip(*row))

The accepted answer only shows files in the current directory's tree. To show all of the tracked files that have been committed (on the current branch), use

git ls-tree --full-tree --name-only -r HEAD

• --full-tree makes the command run as if you were in the repo's root directory.
• -r recurses into subdirectories. Combined with --full-tree, this gives you all committed, tracked files.
• --name-only removes SHA / permission info for when you just want the file paths.
• HEAD specifies which branch you want the list of tracked, committed files for. You could change this to master or any other branch name, but HEAD is the commit you have checked out right now.

This is the method from the accepted answer to the ~duplicate question https://stackoverflow.com/a/8533413/4880003.

First, make sure you're logged into heroku:

heroku login 

Enter your credentials.

It's common to get this error when using a cloned git repo onto a new machine. Even if your heroku credentials are already on the machine, there is no link between the cloned repo and heroku locally yet. To do this, cd into the root dir of the cloned repo and run

heroku git:remote -a yourapp

if (typeof EmpName != 'undefined' && EmpName) {

will evaluate to true if value is not:

• null

• undefined

• NaN

• empty string ("")

• 0

• false

This line makes selects with the readonly attribute read-only:

$('select[readonly=readonly] option:not(:selected)').prop('disabled', true);

You might find it easier to understand by using a simple subquery

SELECT `settings`.*, (
    SELECT `value` FROM `character_settings`
    WHERE `character_settings`.`setting_id` = `settings`.`id`
      AND `character_settings`.`character_id` = '1') AS cv_value
FROM `settings`

The subquery is allowed to return null, so you don't have to worry about JOIN/WHERE in the main query.

Sometimes, this works faster in MySQL, but compare it against the LEFT JOIN form to see what works best for you.

SELECT s.*, c.value
FROM settings s
LEFT JOIN character_settings c ON c.setting_id = s.id AND c.character_id = '1'

Just solved this problem! I know the question is quite old, but I just had this same problem and none of the answers above helped to solve it.

Assuming the actual domain name you want to use is specified in your c:\windows\System32\drivers\etc\hosts and your configurations in apache\conf\httpd.conf and apache\conf\extra\httpd-vhots.conf are right, your problem might be the same as mine:

In Apache's htdocs directory I had a shortcut linking to the actual project I wanted to see in the browser. It turns out, Apache doesn't understand shortcuts. My solution was to create a proper symlink:

In windows, and within the httdocs directory, I ran this command in the terminal:

mklink /d ple <your project directory with index.html> 

This created a proper symlink in the httpdocs directory. After restarting the Apache service and then reloading the page, I was able to see my website up :)

To extract the real part of a complex-valued expression z, use the notation as __real__ z. Similarly, use __imag__ attribute on the z to extract the imaginary part.

For example;

__complex__ float z;
float r;
float i;
r = __real__ z;
i = __imag__ z;

r is the real part of the complex number "z" i is the imaginary part of the complex number "z"

Use of the argmin method for numpy arrays.

import numpy as np
np.argmin(myList)

However, it is not the fastest method: it is 3 times slower than OP's answer on my computer. It may be the most concise one though.

It's because you can't resolve the host name Maybe DNS problems, host is unreachable...

try to use IP address instead of host name... ping this host name... nslookup it...

There is no need extension or any extra func anymore. You can write like that :

firstDictionary.merge(secondDictionary) { (value1, value2) -> AnyObject in
        return object2 // what you want to return if keys same.
    }

My favorite way to run this query is with a not exists clause. I believe this is the most efficient way to run this sort of query:

select o.OrderNumber,
       li.Quantity,
       li.Description
from Orders as o
inner join LineItems as li
on li.OrderID = o.OrderID
where not exists (
    select 1
    from LineItems as li_later
    where li_later.OrderID = o.OrderID
    and li_later.LineItemGUID > li.LineItemGUID
    )

But I have not tested this method against other methods suggested here.

I have noticed that if utilised progrmmatically it renders incomplete (entire form simply doesn't "paint" anything) if used before panel1.Controls.Add(dataGridView); then dataGridView.Columns["ID"].Visible = false; will break the entire form and make it blank, so to get round that set this AFTER EG:

 panel1.Controls.Add(dataGridView);
 dataGridView.Columns["ID"].Visible = false; 
 //works

 dataGridView.Columns["ID"].Visible = false; 
 panel1.Controls.Add(dataGridView);
 //fails miserably

As apparantly no one mentioned it: you can also use the Numpy Docstring Standard. It is widely used in the scientific community.

• The specification of the format from numpy together with an example
• You have a sphinx extension to render it: numpydoc
• And an example of how beautiful a rendered docstring can look like: http://docs.scipy.org/doc/numpy/reference/generated/numpy.mean.html

The Napolean sphinx extension to parse Google-style docstrings (recommended in the answer of @Nathan) also supports Numpy-style docstring, and makes a short comparison of both.

And last a basic example to give an idea how it looks like:

def func(arg1, arg2):
    """Summary line.

    Extended description of function.

    Parameters
    ----------
    arg1 : int
        Description of arg1
    arg2 : str
        Description of arg2

    Returns
    -------
    bool
        Description of return value

    See Also
    --------
    otherfunc : some related other function

    Examples
    --------
    These are written in doctest format, and should illustrate how to
    use the function.

    >>> a=[1,2,3]
    >>> print [x + 3 for x in a]
    [4, 5, 6]
    """
    return True

Add the following to your build.gradle

apply plugin: 'eclipse'

and browse to the project directory

gradle eclipse

To achieve a generic solution, why not do this:

$(':reset').live('click', function(){
    var $r = $(this);
    setTimeout(function(){ 
        $r.closest('form').find('.select2-offscreen').trigger('change'); 
    }, 10);
});

This way: You'll not have to make a new logic for each select2 on your application.

And, you don't have to know the default value (which, by the way, does not have to be "" or even the first option)

Finally, setting the value to :selected would not always achieve a true reset, since the current selected might well have been set programmatically on the client, whereas the default action of the form select is to return input element values to the server-sent ones.

EDIT: Alternatively, considering the deprecated status of live, we could replace the first line with this:

$('form:has(:reset)').on('click', ':reset', function(){

or better still:

$('form:has(:reset)').on('reset', function(){

PS: I personally feel that resetting on reset, as well as triggering blur and focus events attached to the original select, are some of the most conspicuous "missing" features in select2!

I'm not sure about what you're trying to do... maybe something like

SELECT gid, COUNT(*) AS num FROM gd GROUP BY gid HAVING num > 10 ORDER BY lastupdated DESC

Automated Process:

Use this tool (uses the new apksigner from Google):

https://github.com/patrickfav/uber-apk-signer

^{Disclaimer: Im the developer :)}

Manual Process:

Step 1: Generate Keystore (only once)

You need to generate a keystore once and use it to sign your unsigned apk. Use the keytool provided by the JDK found in %JAVA_HOME%/bin/

keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app

Step 2 or 4: Zipalign

zipalign which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/ is a mandatory optimization step if you want to upload the apk to the Play Store.

zipalign -p 4 my.apk my-aligned.apk

Note: when using the old jarsigner you need to zipalign AFTER signing. When using the new apksigner method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).

You can verify the alignment with

zipalign -c 4 my-aligned.apk

Step 3: Sign & Verify

Using build-tools 24.0.2 and older

Use jarsigner which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/ and use it like so:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name

and can be verified with

jarsigner -verify -verbose my_application.apk

Using build-tools 24.0.3 and newer

Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Therefore, Google implemented their own apk signer called apksigner (duh!) The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/ (the .jar is in the /lib subfolder). Use it like this

apksigner sign --ks my.keystore my-app.apk --ks-key-alias alias_name

and can be verified with

apksigner verify my-app.apk

The official documentation can be found here.

I wrote a simple function:

function push(&$arr,$new) {
    $arr = array_merge($arr,$new);
}

so that I can "upsert" new element easily:

push($my_array, ['a'=>1,'b'=>2])

This can be initiated however you want. timeout is the method i used to keep it on the top of the hour.

I had the need for every hour to begin a code block on the hour. So this would start at server startup and run the interval hourly. Basicaly the initial run is to begin the interval within the same minute. So in a second from init, run immediately then on every 5 seconds.

var interval = 1000;
var timing =function(){
    var timer = setInterval(function(){
        console.log(interval);
        if(interval == 1000){ /*interval you dont want anymore or increment/decrement */
            interval = 3600000; /* Increment you do want for timer */
            clearInterval(timer);
            timing();
        }
    },interval);
}
timing();

Alternately if you wanted to just have something happen at start and then forever at a specific interval you could just call it at the same time as the setInterval. For example:

var this = function(){
 //do
}
setInterval(function(){
  this()
},3600000)
this()

Here we have this run the first time and then every hour.

Should use ngChange instead of ngClick if trigger source is not from click.

Is the below what you want ? what exactly doesn't work in your case ?

var myApp = angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.value = "none" ;
    $scope.isChecked = false;
    $scope.checkStuff = function () {
        $scope.isChecked = !$scope.isChecked;
    }
}


<div ng-controller="MyCtrl">
    <input type="radio" ng-model="value" value="one" ng-change="checkStuff()" />
    <span> {{value}} isCheck:{{isChecked}} </span>
</div>   

Sharing one more way of checking if a key exists using boolean operators.

d = {'a': 1, 'b':2}
keys = 'abcd'

for k in keys:
    x = (k in d and 'blah') or 'boo'
    print(x) 

This returns

>>> blah
>>> blah
>>> boo
>>> boo

Explanation

First you should know that in Python, 0, None, or objects with zero length evaluate to False. Everything else evaluates to True. Boolean operations are evaluated left to right and return the operand not True or False.

Let's see an example:

>>> 'Some string' or 1/0 
'Some string'
>>>

Since 'Some string' evaluates to True, the rest of the or is not evaluated and there is no division by zero error raised.

But if we switch the order 1/0 is evaluated first and raises an exception:

>>> 1/0 or 'Some string'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: division by zero
>>> 

We can use this for pattern for checking if a key exists.

(k in d and 'blah')

does the same as

if k in d:
    'blah'
else:
    False

This already returns the correct result if the key exists, but we want it to print 'boo' when it doesn't. So, we take the result and or it with 'boo'

>>> False or 'boo'
'boo'
>>> 'blah' or 'boo'
'blah'
>>> 

Your stylesheet should be thought of as a static table of available variables that your html document can call on based on what you need to display. The logic should be in your javascript and html, use javascript to dynamically apply attributes based on conditions if you really need to. Stylesheets are not the place for logic.

I created blog post on the topic. It contains also link to Github repository with working example.

The trick is using test configuration, where you override original spring bean with fake one. You can use @Primary and @Profile annotations for this trick.

Here's a benchmark to compare a Go for statement with a ForClause and a Go range statement using the iter package.

iter_test.go

package main

import (
    "testing"

    "github.com/bradfitz/iter"
)

const loops = 1e6

func BenchmarkForClause(b *testing.B) {
    b.ReportAllocs()
    j := 0
    for i := 0; i < b.N; i++ {
        for j = 0; j < loops; j++ {
            j = j
        }
    }
    _ = j
}

func BenchmarkRangeIter(b *testing.B) {
    b.ReportAllocs()
    j := 0
    for i := 0; i < b.N; i++ {
        for j = range iter.N(loops) {
            j = j
        }
    }
    _ = j
}

// It does not cause any allocations.
func N(n int) []struct{} {
    return make([]struct{}, n)
}

func BenchmarkIterAllocs(b *testing.B) {
    b.ReportAllocs()
    var n []struct{}
    for i := 0; i < b.N; i++ {
        n = iter.N(loops)
    }
    _ = n
}

Output:

$ go test -bench=. -run=.
testing: warning: no tests to run
PASS

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

Another possibility is:

create or replace FUNCTION getNth (
  input varchar2,
  nth number
) RETURN varchar2 AS
  nthVal varchar2(80);
BEGIN
  with candidates (s,e,n) as (
      select 1, instr(input,',',1), 1 from dual
      union all
      select e+1, instr(input,',',e+1), n+1
        from candidates where e > 0)
  select substr(input,s,case when e > 0 then e-s else length(input) end) 
    into nthVal
    from candidates where n=nth;
  return nthVal;
END getNth;

It's a little too expensive to run, as it computes the complete split every time the caller asks for one of the items in there...

When you allow the 9000 port to firewall on your desired operating System the following error "ERROR: Sonar server 'http://localhost:9000' can not be reached" will remove successfully.In ubuntu it is just like as by typing the following command in terminal "sudo ufw allow 9000/tcp" this error will removed from the Jenkins server by clicking on build now in jenkins.

I was able to import the module within the function (only) that would require the objects from this module:

def my_func():
    import Foo
    foo_instance = Foo()

You can use URL.createObjectURL

    function img_pathUrl(input){
        $('#img_url')[0].src = (window.URL ? URL : webkitURL).createObjectURL(input.files[0]);
    }

#img_url {
  background: #ddd;
  width:100px;
  height: 90px;
  display: block;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<img src="" id="img_url" alt="your image">
<br>
<input type="file" id="img_file" onChange="img_pathUrl(this);">

You can debug this in many different ways. Here's my approach.

localsettings.py:

DEBUG = False
DEBUG404 = True

urls.py:

from django.conf import settings
import os

if settings.DEBUG404:
    urlpatterns += patterns('',
        (r'^static/(?P<path>.*)$', 'django.views.static.serve',
         {'document_root': os.path.join(os.path.dirname(__file__), 'static')} ),
    )

Be sure to read the docs ;)

https://docs.djangoproject.com/en/2.0/howto/static-files/#limiting-use-to-debug-true

The way to use should still be the toInteger(), because it is not really deprecated.

int value = '99'.toInteger()

The String version is deprecated, but the CharSequence is an Interface that a String implements. So, using a String is ok, because your code will still works even when the method will only work with CharSequence. Same goes for isInteger()

See this question for reference : How to convert a String to CharSequence?

I commented, because the notion of deprecated on this method got me confuse and I want to avoid that for other people.

This answer is for Jenkins

1. Go to your Jenkins home page ? Manage Jenkins ? Script Console

   

2. Run the following script there. Change copy_folder to your project name

Code:

def jobName = "copy_folder"
def job = Jenkins.instance.getItem(jobName)
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()

Depending on what kind of objects you are checking you may be able to use some of the classes in the apache commons such as: apache commons lang and apache commons collections

Example:

String foo;
...
if( StringUtils.isBlank( foo ) ) {
   ///do something
}

or (depending on what you need to check):

String foo;
...
if( StringUtils.isEmpty( foo ) ) {
   ///do something
}

The StringUtils class is only one of many; there are quite a few good classes in the commons that do null safe manipulation.

Here follows an example of how you can use null vallidation in JAVA when you include apache library(commons-lang-2.4.jar)

public DOCUMENT read(String xml, ValidationEventHandler validationEventHandler) {
    Validate.notNull(validationEventHandler,"ValidationHandler not Injected");
    return read(new StringReader(xml), true, validationEventHandler);
}

And if you are using Spring, Spring also has the same functionality in its package, see library(spring-2.4.6.jar)

Example on how to use this static classf from spring(org.springframework.util.Assert)

Assert.notNull(validationEventHandler,"ValidationHandler not Injected");

This is incredibly old, but I stumbled across it trying to find an answer to a different question.

my question is how do you get the values from both map keys in the arraylist?

for (String key : map.keyset()) {
  list.add(key + "|" + map.get(key));
}

the Map size always return a value of 2, which is just the elements

I think you may be confused by the functionality of HashMap. HashMap only allows 1 to 1 relationships in the map.

For example if you have:

String TAG_FOO = "FOO";
String TAG_BAR = "BAR";

and attempt to do something like this:

ArrayList<String> bars = ArrayList<>("bar","Bar","bAr","baR");
HashMap<String,String> map = new HashMap<>();
for (String bar : bars) {
  map.put(TAG_BAR, bar);
}

This code will end up setting the key entry "BAR" to be associated with the final item in the list bars.

In your example you seem to be confused that there are only two items, yet you only have two keys recorded which leads me to believe that you've simply overwritten the each key's field multiple times.

If you use

git fetch --dry-run -v <link/to/remote/git/repo>

you'll get feedback about whether it is up-to-date. So basically, you just need to add the "verbose" option to the answer given before.

In UBUNTU use:

$ export NODE_ENV=test

openURL() has been deprecated in iOS 10. Here is the new syntax:

if let url = URL(string: "tel://\(busPhone)") {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

You just subindex it with [:5] indicating that you want (up to) the first 5 elements.

>>> [1,2,3,4,5,6,7,8][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]
>>> x = [6,7,8,9,10,11,12]
>>> x[:5]
[6, 7, 8, 9, 10]

Also, putting the colon on the right of the number means count from the nth element onwards -- don't forget that lists are 0-based!

>>> x[5:]
[11, 12]

As much as I hate to rely on Windows Excel proprietary software, which is not cross-platform, my testing of csvkit for .xls, which uses xlrd under the hood, failed to correctly parse dates (even when using the commandline parameters to specify strptime format).

For example, this xls file, when parsed with csvkit, will convert cell G1 of 12/31/2002 to 37621, whereas when converted to csv via excel -> save_as (using below) cell G1 will be "December 31, 2002".

        input_dir='C:\\data\\xls\\',
        output_dir='C:\\data\\csv\\'

    self.batchConvertXlsToCsv()

The above will take an input_dir containing .xls and output them to output_dir as .csv -- it will assert that there is exactly 1 non-empty sheet in the .xls; if you need to handle multiple sheets into multiple csv then you'll need to edit saveWorkbookAsCsv.

CAUSE: "Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app." In this case, "ACCESS_FINE_LOCATION" is a "dangerous permission and for that reason, you get this 'java.lang.SecurityException: "gps" location provider requires ACCESS_FINE_LOCATION permission.' error (https://developer.android.com/training/permissions/requesting.html).

SOLUTION: Implementing the code provided at https://developer.android.com/training/permissions/requesting.html under the "Request the permissions you need" and "Handle the permissions request response" headings.

I also read the Spring docs, as lapkritinis suggested - and luckily this brought me on the right path! But I don´t think, that the Spring docs explain this good right now. At least for me, they aren´t consistent IMHO.

The original problem/question is on what to do, if you upgrade an existing Spring Boot 1.5.x application to 2.0.x, which is using PostgreSQL/Hibernate. The main reason, you get your described error, is that Spring Boot 2.0.x uses HikariCP instead of Tomcat JDBC pooling DataSource as a default - and Hikari´s DataSource doesn´t know the spring.datasource.url property, instead it want´s to have spring.datasource.jdbc-url (lapkritinis also pointed that out).

So far so good. BUT the docs also suggest - and that´s the problem here - that Spring Boot uses spring.datasource.url to determine, if the - often locally used - embedded Database like H2 has to back off and instead use a production Database:

You should at least specify the URL by setting the spring.datasource.url property. Otherwise, Spring Boot tries to auto-configure an embedded database.

You may see the dilemma. If you want to have your embedded DataBase like you´re used to, you have to switch back to Tomcat JDBC. This is also much more minimally invasive to existing applications, as you don´t have to change source code! To get your existing application working after the Spring Boot 1.5.x --> 2.0.x upgrade with PostgreSQL, just add tomcat-jdbc as a dependency to your pom.xml:

    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-jdbc</artifactId>
    </dependency>

And then configure Spring Boot to use it accordingly inside application.properties:

spring.datasource.type=org.apache.tomcat.jdbc.pool.DataSource

Hope to help some folks with this, was quite a time consuming problem. I also hope my beloved Spring folks update the docs - and the way new Hikari pool is configured - to get a more consistent Spring Boot user experience :)

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.

Well, quick answer would to take a look at the 'scp' manpage, or perhaps rsync - depending exactly on what you need to copy. If you had to, you could even do tar-over-ssh:

tar cvf - | ssh server tar xf -

I strongly recommend the following:

<img src="<?php echo get_stylesheet_directory_uri(); ?>/img-folder/your_image.jpg">

It works for almost any file you want to add to your wordpress project, be it image or CSS.

AngularJs has "Services" and "Factories" just for problems like yours.These are used to have something global between Controllers, Directives, Other Services or any other angularjs components..You can defined functions, store data, make calculate functions or whatever you want inside Services and use them in AngularJs Components as Global.like

angular.module('MyModule', [...])
  .service('MyService', ['$http', function($http){
    return {
       users: [...],
       getUserFriends: function(userId){
          return $http({
            method: 'GET',
            url: '/api/user/friends/' + userId
          });
       }
       ....
    }
  }])

Hello this is a snippet from an old project of mine that uses curl to get ip information from some free ip databases services which reply in json format. I think it might help you.

$ip_srv = array("http://freegeoip.net/json/$this->ip","http://smart-ip.net/geoip-json/$this->ip");

getUserLocation($ip_srv);

Function:

function getUserLocation($services) {

        $ctx = stream_context_create(array('http' => array('timeout' => 15))); // 15 seconds timeout

        for ($i = 0; $i < count($services); $i++) {

            // Configuring curl options
            $options = array (
                CURLOPT_RETURNTRANSFER => true, // return web page
                //CURLOPT_HEADER => false, // don't return headers
                CURLOPT_HTTPHEADER => array('Content-type: application/json'),
                CURLOPT_FOLLOWLOCATION => true, // follow redirects
                CURLOPT_ENCODING => "", // handle compressed
                CURLOPT_USERAGENT => "test", // who am i
                CURLOPT_AUTOREFERER => true, // set referer on redirect
                CURLOPT_CONNECTTIMEOUT => 5, // timeout on connect
                CURLOPT_TIMEOUT => 5, // timeout on response
                CURLOPT_MAXREDIRS => 10 // stop after 10 redirects
            ); 

            // Initializing curl
            $ch = curl_init($services[$i]);
            curl_setopt_array ( $ch, $options );

            $content = curl_exec ( $ch );
            $err = curl_errno ( $ch );
            $errmsg = curl_error ( $ch );
            $header = curl_getinfo ( $ch );
            $httpCode = curl_getinfo ( $ch, CURLINFO_HTTP_CODE );

            curl_close ( $ch );

            //echo 'service: ' . $services[$i] . '</br>';
            //echo 'err: '.$err.'</br>';
            //echo 'errmsg: '.$errmsg.'</br>';
            //echo 'httpCode: '.$httpCode.'</br>';
            //print_r($header);
            //print_r(json_decode($content, true));

            if ($err == 0 && $httpCode == 200 && $header['download_content_length'] > 0) {

                return json_decode($content, true);

            } 

        }
    }

The most efficient selector you can use is an attribute selector.

 input[name="btnPage"]:hover {/*your css here*/}

Here's a live demo: http://tinkerbin.com/3G6B93Cb

Many good answers here already, although you also need to keep in mind that if you are doing long-running processing on the UI thread (generally a bad idea), then you won't see the marquee moving either.

In C++ there is a concept of constructor's initialization list, which is where you can and should call the base class' constructor and where you should also initialize the data members. The initialization list comes after the constructor signature following a colon, and before the body of the constructor. Let's say we have a class A:

class A : public B
{
public:
  A(int a, int b, int c);
private:
  int b_, c_;
};

Then, assuming B has a constructor which takes an int, A's constructor may look like this:

A::A(int a, int b, int c) 
  : B(a), b_(b), c_(c) // initialization list
{
  // do something
}

As you can see, the constructor of the base class is called in the initialization list. Initializing the data members in the initialization list, by the way, is preferable to assigning the values for b_, and c_ inside the body of the constructor, because you are saving the extra cost of assignment.

Keep in mind, that data members are always initialized in the order in which they are declared in the class definition, regardless of their order in the initialization list. To avoid strange bugs, which may arise if your data members depend on each other, you should always make sure that the order of the members is the same in the initialization list and the class definition. For the same reason the base class constructor must be the first item in the initialization list. If you omit it altogether, then the default constructor for the base class will be called automatically. In that case, if the base class does not have a default constructor, you will get a compiler error.

I was looking into this but wanted to have a different transition rate for in and out.

This is what I ended up doing:

//css
.addedClass {
    background: #5eb4fc;
}

// js
function setParentTransition(id, prop, delay, style, callback) {
    $(id).css({'-webkit-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-moz-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-o-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'transition' : prop + ' ' + delay + ' ' + style});
    callback();
}
setParentTransition(id, 'background', '0s', 'ease', function() {
    $('#elementID').addClass('addedClass');
});

setTimeout(function() {
    setParentTransition(id, 'background', '2s', 'ease', function() {
        $('#elementID').removeClass('addedClass');
    });
});

This instantly turns the background color to #5eb4fc and then slowly fades back to normal over 2 seconds.

Here's a fiddle

I'm not aware of any way to programmatically create these URLs, but the existing username space (www.facebook.com/something) works on fb.me also (e.g. http://fb.me/facebook )

The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.

That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

<style>
  html, body {
    height: 100%;
  }
  #tableContainer-1 {
    height: 100%;
    width: 100%;
    display: table;
  }
  #tableContainer-2 {
    vertical-align: middle;
    display: table-cell;
    height: 100%;
  }
  #myTable {
    margin: 0 auto;
  }
</style>
<div id="tableContainer-1">
  <div id="tableContainer-2">
    <table id="myTable" border>
      <tr><td>Name</td><td>J W BUSH</td></tr>
      <tr><td>Proficiency</td><td>PHP</td></tr>
      <tr><td>Company</td><td>BLAH BLAH</td></tr>
    </table>
  </div>
</div>

As of this writing, in OS X, it will usually look like this

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --allow-file-access-from-files

If you are a freak like me, and put your apps in ~/Applications, then it will be

"/Users/yougohere/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --allow-file-access-from-files

If neither of those are working, then type chrome://version in your Chrome address bar, and it will tell you what "command line" invocation you should be using. Just add --allow-file-access-from-files to that.

You are using a function for which the compiler has not seen a declaration ("prototype") yet.

For example:

int main()
{
    fun(2, "21"); /* The compiler has not seen the declaration. */       
    return 0;
}

int fun(int x, char *p)
{
    /* ... */
}

You need to declare your function before main, like this, either directly or in a header:

int fun(int x, char *p);

Try Boost::Program Options. It allows you to read and parse command lines as well as config files.

Here It is actually returning tuple.

If you execute this code in Python 3:

def get():
    a = 3
    b = 5
    return a,b
number = get()
print(type(number))
print(number)

Output :

<class 'tuple'>
(3, 5)

But if you change the code line return [a,b] instead of return a,b and execute :

def get():
    a = 3
    b = 5
    return [a,b]
number = get()
print(type(number))
print(number)

Output :

<class 'list'>
[3, 5]

It is only returning single object which contains multiple values.

There is another alternative to return statement for returning multiple values, use yield( to check in details see this What does the "yield" keyword do in Python?)

Sample Example :

def get():
    for i in range(5):
        yield i
number = get()
print(type(number))
print(number)
for i in number:
    print(i)

Output :

<class 'generator'>
<generator object get at 0x7fbe5a1698b8>
0
1
2
3
4

GET requests can have "Accept" headers, which say which types of content the client understands. The server can then use that to decide which content type to send back.

They're optional though.

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1

What you are asking for is a specialized form of compression. xdelta3 was designed for this particular kind of compression, and there's a python binding for it, but you could probably get away with using zlib directly. You'd want to use zlib.compressobj and zlib.decompressobj with the zdict parameter set to your "base word", e.g. afrykanerskojezyczny.

Caveats are zdict is only supported in python 3.3 and higher, and it's easiest to code if you have the same "base word" for all your diffs, which may or may not be what you want.

I spent a long time looking for solutions, and found this answer.

It looks like, in order to get what you (and I) want, you need the combination of plt.ion(), plt.show() (not with block=False) and, most importantly, plt.pause(.001) (or whatever time you want). The pause is needed because the GUI events happen while the main code is sleeping, including drawing. It's possible that this is implemented by picking up time from a sleeping thread, so maybe IDEs mess with that—I don't know.

Here's an implementation that works for me on python 3.5:

import numpy as np
from matplotlib import pyplot as plt

def main():
    plt.axis([-50,50,0,10000])
    plt.ion()
    plt.show()

    x = np.arange(-50, 51)
    for pow in range(1,5):   # plot x^1, x^2, ..., x^4
        y = [Xi**pow for Xi in x]
        plt.plot(x, y)
        plt.draw()
        plt.pause(0.001)
        input("Press [enter] to continue.")

if __name__ == '__main__':
    main()

Its work perfectly

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL;

But if you want more precise in table then you can try AFTER.

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL AFTER `column_name`;

It will add LastUpdate column after specified column name (column_name).

You can try:

WebElement getmenu= driver.findElement(By.xpath("//*[@id='ui-id-2']/span[2]")); //xpath the parent

Actions act = new Actions(driver);
act.moveToElement(getmenu).perform();

Thread.sleep(3000);
WebElement clickElement= driver.findElement(By.linkText("Sofa L"));//xpath the child
act.moveToElement(clickElement).click().perform();

If you had case the web have many category, use the first method. For menu you wanted, you just need the second method.

A bug or security vulnerability in the server (either Apache or the PHP engine), or your own PHP code, might allow an attacker to obtain access to your code.

For instance if you have a PHP script to allow people to download files, and an attacker can trick this script into download some of your PHP files, then your code can be leaked.

Since it's impossible to eliminate all bugs from the software you're using, if someone really wants to steal your code, and they have enough resources, there's a reasonable chance they'll be able to.

However, as long as you keep your server up-to-date, someone with casual interest is not able to see the PHP source unless there are some obvious security vulnerabilities in your code.

Read the Security section of the PHP manual as a starting point to keeping your code safe.

You can also try:

string res = string.Join("", sample.Split(Environment.NewLine.ToCharArray())

Environment.NewLine should make it independent of platform.

Recommended Read:

Environment.NewLine Property

The main difference between return false and event.preventDefault() is that your code below return false will not be executed and in event.preventDefault() case your code will execute after this statement.

When you write return false it do the following things for you behind the scenes.

* Stops callback execution and returns immediately when called.
* event.stopPropagation();
* event.preventDefault();

I use the package enumitem. You may then set such margins when you declare your lists (enumerate, description, itemize):

\begin{itemize}[leftmargin=0cm]
    \item Foo
    \item Bar
\end{itemize}

Naturally, the package provides lots of other nice customizations for lists (use 'label=' to change the bullet, use 'itemsep=' to change the spacing between items, etc...)

I don't think, You really need to do that just define your TextView in layout file like this

<RelativeLayout
    android:layout_width="width"
    android:layout_height="height">
    <TextView
        android:id="@+id/yourid"
        android:layout_centerInParent="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your text" />
</RelativeLayout>

In a very general way and to support SQL server here is

SELECT TOP(N) *
FROM tbl_name
ORDER BY tbl_id DESC

and for the performance, it is not bad (less than one second for more than 10,000 records On Server machine)

I would recommend storing these as numbers in columns of type varchar - one column per "field" (like contry code etc.).

The format should be applied when you interact with a user... that makes it easier to account for format changes for example and will help esp. when your application goes international...

Your sprite is created mid way through the playerSprite function... it also goes out of scope and ceases to exist at the end of that same function. The sprite must be created where you can pass it to playerSprite to initialize it and also where you can pass it to your draw function.

Perhaps declare it above your first while?

You can use Cursor.Current.

// Set cursor as hourglass
Cursor.Current = Cursors.WaitCursor;

// Execute your time-intensive hashing code here...

// Set cursor as default arrow
Cursor.Current = Cursors.Default;

However, if the hashing operation is really lengthy (MSDN defines this as more than 2-7 seconds), you should probably use a visual feedback indicator other than the cursor to notify the user of the progress. For a more in-depth set of guidelines, see this article.

Edit:
As @Am pointed out, you may need to call Application.DoEvents(); after Cursor.Current = Cursors.WaitCursor; to ensure that the hourglass is actually displayed.

The only editor I know of that has syntax highlighting and a fallback to a textarea is Mozilla Bespin. Google around for embedding Bespin to see how to embed the editor. The only site I know of that uses this right now is the very alpha Mozilla Jetpack Gallery (in the submit a Jetpack page) and you may want to see how they include it.

There's also a blog post on embedding and reusing the Bespin editor that may help you.

html code here

    <input id="result" style="width:300px"/>some example text
    <button onclick="copyToClipboard('result')">Copy P1</button>
    <input type="text" style="width:400px" placeholder="Paste here for test" />

JS CODE:

     function copyToClipboard(elementId) {

                      // Create a "hidden" input
                      var aux = document.createElement("input");

                      aux.setAttribute("value", document.getElementById(elementId).value);
                      // Append it to the body
                      document.body.appendChild(aux);
                      // Highlight its content
                      aux.select();
                      // Copy the highlighted text
                      document.execCommand("copy");
                      // Remove it from the body
                      document.body.removeChild(aux);
                    }

I prefer to use the @ symbol so I see the query exactly as I can copy and paste into a query file:

string name = "Joe";
string gender = "M";
string query = String.Format(@"
SELECT
   *
FROM
   tableA
WHERE
   Name = '{0}' AND
   Gender = '{1}'", name, gender);

It's really great with long complex queries. Nice thing is it keeps tabs and line feeds so pasting into a query browser retains the nice formatting

For a string specifically, the quickest way is to use the StringContent constructor

response.Content = new StringContent("Your response text");

There are a number of additional HttpContent class descendants for other common scenarios.

If you want to use jQuery. I found this:

http://www.jquerysdk.com/api/jQuery.htmlspecialchars

(part of jquery.string plugin offered by jQuery SDK)

The problem with Prototype I believe is that it extends base objects in JavaScript and will be incompatible with any jQuery you may have used. Of course, if you are already using Prototype and not jQuery, it won't be a problem.

EDIT: Also there is this, which is a port of Prototype's string utilities for jQuery:

http://stilldesigning.com/dotstring/

private int user_movie_matrix[][];Th. should be `private int user_movie_matrix[][];.

private int user_movie_matrix[][]; should be private static int user_movie_matrix[][];

cfiltering(numberOfUsers, numberOfMovies); should be new cfiltering(numberOfUsers, numberOfMovies);

Whether or not the code works as intended after these changes is beyond the scope of this answer; there were several syntax/scoping errors.

I've try install curl-ca-bundle with brew, but the package is no available more:

$ brew install curl-ca-bundle

The solution that worked to me on Mac was:

 $ cd /usr/local/etc/openssl/certs/
 $ sudo curl -O http://curl.haxx.se/ca/cacert.pem

Add this line in your ~/.bash_profile (or ~/.zshrc for zsh):

export SSL_CERT_FILE=/usr/local/etc/openssl/certs/cacert.pem

Then update your terminal:

$ source ~/.bash_profile

It will look better if you reserve space for the common labels by making invisible labels for the subplot in the bottom left corner. It is also good to pass in the fontsize from rcParams. This way, the common labels will change size with your rc setup, and the axes will also be adjusted to leave space for the common labels.

fig_size = [8, 6]
fig, ax = plt.subplots(5, 2, sharex=True, sharey=True, figsize=fig_size)
# Reserve space for axis labels
ax[-1, 0].set_xlabel('.', color=(0, 0, 0, 0))
ax[-1, 0].set_ylabel('.', color=(0, 0, 0, 0))
# Make common axis labels
fig.text(0.5, 0.04, 'common X', va='center', ha='center', fontsize=rcParams['axes.labelsize'])
fig.text(0.04, 0.5, 'common Y', va='center', ha='center', rotation='vertical', fontsize=rcParams['axes.labelsize'])

The issue is also created if you have setup breakpoints in the code and trying to start tomcat in debug mode post some code overhaul.

Solution is to clear all the breakpoints.

The problem is not with extract, which can certainly handle 'military time'. It looks like you have a default timestamp format which has HH instead of HH24; or at least that's the only way I can see to recreate this:

SQL> select value from nls_session_parameters
  2  where parameter = 'NLS_TIMESTAMP_FORMAT';

VALUE
--------------------------------------------------------------------------------
DD-MON-RR HH24.MI.SSXFF

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

alter session set nls_timestamp_format = 'DD-MON-YYYY HH:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') as timestamp)) from dual
                              *
ERROR at line 1:
ORA-01849: hour must be between 1 and 12

So the simple 'fix' is to set the format to something that does recognise 24-hours:

SQL> alter session set nls_timestamp_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

Although you don't need the to_char at all:

SQL> select extract(hour from cast(sysdate as timestamp)) from dual;

EXTRACT(HOURFROMCAST(SYSDATEASTIMESTAMP))
-----------------------------------------
                                       15

Just to enhance @adivis12 answer, you don't need to do the if statement. Put it like this:

fig, ax = plt.subplots()
for BAR in dict_of_dfs.keys():
    dict_of_dfs[BAR].plot(ax=ax)

For increased performance you should not evaluate the dataframe using your predicate. You can just use the outcome of your predicate directly as illustrated below:

In [1]: import pandas as pd
        import numpy as np
        df = pd.DataFrame(np.random.randn(20,4),columns=list('ABCD'))


In [2]: df.head()
Out[2]:
          A         B         C         D
0 -2.019868  1.227246 -0.489257  0.149053
1  0.223285 -0.087784 -0.053048 -0.108584
2 -0.140556 -0.299735 -1.765956  0.517803
3 -0.589489  0.400487  0.107856  0.194890
4  1.309088 -0.596996 -0.623519  0.020400

In [3]: %time sum((df['A']>0) & (df['B']>0))
CPU times: user 1.11 ms, sys: 53 µs, total: 1.16 ms
Wall time: 1.12 ms
Out[3]: 4

In [4]: %time len(df[(df['A']>0) & (df['B']>0)])
CPU times: user 1.38 ms, sys: 78 µs, total: 1.46 ms
Wall time: 1.42 ms
Out[4]: 4

Keep in mind that this technique only works for counting the number of rows that comply with your predicate.

As an alternate option, if you have the Sqlite Database Browser and are more inclined to a GUI solution, you can edit the sqlite_sequence table where field name is the name of your table. Double click the cell for the field seq and change the value to 0 in the dialogue box that pops up.

You can have almost any character, including most Unicode characters! The exact definition is in the Java Language Specification under section 3.8: Identifiers.

An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. ...

Letters and digits may be drawn from the entire Unicode character set, ... This allows programmers to use identifiers in their programs that are written in their native languages.

An identifier cannot have the same spelling (Unicode character sequence) as a keyword (§3.9), boolean literal (§3.10.3), or the null literal (§3.10.7), or a compile-time error occurs.

However, see this question for whether or not you should do that.

For the total uploaded there doesn't seem to be a way to handle that, but there's something similar to what you want for download. Once readyState is 3, you can periodically query responseText to get all the content downloaded so far as a String (this doesn't work in IE), up until all of it is available at which point it will transition to readyState 4. The total bytes downloaded at any given time will be equal to the total bytes in the string stored in responseText.

For a all or nothing approach to the upload question, since you have to pass a string for upload (and it's possible to determine the total bytes of that) the total bytes sent for readyState 0 and 1 will be 0, and the total for readyState 2 will be the total bytes in the string you passed in. The total bytes both sent and received in readyState 3 and 4 will be the sum of the bytes in the original string plus the total bytes in responseText.

Also i have found another useful link. It is a background hack used like this

.selector { background-size: cover; -ms-behavior: url(/backgroundsize.min.htc); }

https://github.com/louisremi/background-size-polyfill

You can't directly do array2 = array1, because in this case you manipulate the addresses of the arrays (char *) and not of their inner values (char).

What you, conceptually, want is to do is iterate through all the chars of your source (array1) and copy them to the destination (array2). There are several ways to do this. For example you could write a simple for loop, or use memcpy.

That being said, the recommended way for strings is to use strncpy. It prevents common errors resulting in, for example, buffer overflows (which is especially dangerous if array1 is filled from user input: keyboard, network, etc). Like so:

// Will copy 18 characters from array1 to array2
strncpy(array2, array1, 18);

As @Prof. Falken mentioned in a comment, strncpy can be evil. Make sure your target buffer is big enough to contain the source buffer (including the \0 at the end of the string).

As others suggested, you can use String.compareTo(String).

But if you are sorting a list of Strings and you need a Comparator, you don't have to implement it, you can use Comparator.naturalOrder() or Comparator.reverseOrder().

I use fetchObject() here a small example using Symfony 4.4

    <?php 
    use Doctrine\DBAL\Driver\Connection;

    class MyController{

    public function index($username){
      $queryBuilder = $connection->createQueryBuilder();
      $queryBuilder
        ->select('id', 'name')
        ->from('app_user')
        ->where('name = ?')
        ->setParameter(0, $username)
        ->setMaxResults(1);
      $stmUser = $queryBuilder->execute();

      dump($stmUser->fetchObject());

      //get_class_methods($stmUser) -> to see all methods
    }
  }

Response:

{ 
"id": "2", "name":"myuser"
}

PHP scripting is not like other desktop application developing language. In desktop application languages we can set daemon threads to run a background process but in PHP a process is occuring when user request for a page. However It is possible to set a background job using server's cron job functionality which php script runs.

You are trying to read the value of your checkbox before it is loaded. The script runs before the checkbox exists. You need to call your script when the page loads:

<body onload="dosomething()">

Example:

http://jsfiddle.net/jtbowden/6dx6A/

You are also missing a semi-colon after your first assignment.

Try my simple trick:

        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if(url.startsWith("classRegister:")) {                  
                Intent MnRegister = new Intent(getApplicationContext(), register.class); startActivity(MnRegister);
            }               
            view.loadUrl(url);
            return true;
        }

and my html link:

<a href="classRegister:true">Go to register.java</a>

or you can make < a href="classRegister:true" > <- "true" value for class filename

however this script work for mailto link :)

        if (url.startsWith("mailto:")) {
            String[] blah_email = url.split(":");
            Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.setType("text/plain");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{blah_email[1]});
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, what_ever_you_want_the_subject_to_be)");
            Log.v("NOTICE", "Sending Email to: " + blah_email[1] + " with subject: " + what_ever_you_want_the_subject_to_be);
            startActivity(emailIntent);
        }

when you use camera.open; and you finish using the camera write this commend camera.release(); this will stop the camera so you can use it again

Curl will look for a .curlrc file in your home folder when it starts. You can create (or edit) this file and add this line:

proxy = yourproxy.com:8080

Try this

foreach(array_keys($array) as $nmkey)
    {
        echo $nmkey;
    }

This is a part from a REST-Service I´ve written recently.

var select = $("#productSelect")
for (var prop in data) {
    var option = document.createElement('option');
    option.innerHTML = data[prop].ProduktName
    option.value = data[prop].ProduktName;
    select.append(option)
}

The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.

Being specific to Angular2 to 5, we can bind image path using property binding as below. Image path is enclosed by the single quotation marks.

Sample example

<img [src]="'assets/img/klogo.png'" alt="image">

Check out this SO question's accepted solution. Substitute your own filename for basename($File) and change filesize($File) to strlen($your_string). (You may want to use mb_strlen just in case the string contains multibyte characters.)

I am currently using Rob de la Cruz's reply:

Object.keys(obj)

And in a file loaded early on I have some lines of code borrowed from elsewhere on the Internet which cover the case of old versions of script interpreters that do not have Object.keys built in.

if (!Object.keys) {
    Object.keys = function(object) {
        var keys = [];
        for (var o in object) {
            if (object.hasOwnProperty(o)) {
                keys.push(o);
            }
        }
        return keys;
    };
}

I think this is the best of both worlds for large projects: simple modern code and backwards compatible support for old versions of browsers, etc.

Effectively it puts JW's solution into the function when Rob de la Cruz's Object.keys(obj) is not natively available.

The key part is that I am reducing the scope of the problem: I forbid indirect execution of the script via the path (as in /bin/sh [script path relative to path component]).

This can be detected because $0 will be a relative path which does not resolve to any file relative to the current folder. I believe that direct execution using the #! mechanism always results in an absolute $0, including when the script is found on the path.

I also require that the pathname and any pathnames along a chain of symbolic links only contain a reasonable subset of characters, notably not \n, >, * or ?. This is required for the parsing logic.

There are a few more implicit expectations which I will not go into (look at this answer), and I do not attempt to handle deliberate sabotage of $0 (so consider any security implications). I expect this to work on almost any Unix-like system with a Bourne-like /bin/sh.

#!/bin/sh
(
    path="${0}"
    while test -n "${path}"; do
        # Make sure we have at least one slash and no leading dash.
        expr "${path}" : / > /dev/null || path="./${path}"
        # Filter out bad characters in the path name.
        expr "${path}" : ".*[*?<>\\]" > /dev/null && exit 1
        # Catch embedded new-lines and non-existing (or path-relative) files.
        # $0 should always be absolute when scripts are invoked through "#!".
        test "`ls -l -d "${path}" 2> /dev/null | wc -l`" -eq 1 || exit 1
        # Change to the folder containing the file to resolve relative links.
        folder=`expr "${path}" : "\(.*/\)[^/][^/]*/*$"` || exit 1
        path=`expr "x\`ls -l -d "${path}"\`" : "[^>]* -> \(.*\)"`
        cd "${folder}"
        # If the last path was not a link then we are in the target folder.
        test -n "${path}" || pwd
    done
)

You may try to_char(now()::date, 'yyyy')
If text, you've to cast your text to date to_char('2018-01-01'::date, 'yyyy')

Here is my whole code of a map activity with 4 clickable markers. Click on a marker shows an info window, and after click on info window you are going to another activity: English, German, Spanish or Italian. If you want to use OnMarkerClickListener in spite of OnInfoWindowClickListener, you just have to swap this line:

mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener()

to this:

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener()

this line:

public void onInfoWindowClick(Marker arg0)

to this:

public boolean onMarkerClick(Marker arg0)

and at the end of the method "onMarkerClick":

return true;

Enclosed in {} represents an object; enclosed in [] represents an array, there can be multiple objects in the array
example object :

{
    "brand": "bwm", 
    "price": 30000
}


{
    "brand": "benz", 
    "price": 50000
}

example array:

[
    {
        "brand": "bwm", 
        "price": 30000
    }, 
    {
        "brand": "benz", 
        "price": 50000
    }
]

In order to use JSON more beautifully, you can go here JSON Viewer do format

    words = re.findall(r"([a-zA-Z\-]+)", file.read())

Another alternative with data.table.

EXAMPLE DATA

dt1 <- data.table(df1)

If it's errors you want to hide you can do it like this

$ErrorActionPreference = "SilentlyContinue"; #This will hide errors
$someObject.SomeFunction();
$ErrorActionPreference = "Continue"; #Turning errors back on

First, use git log to see the log, pick the commit you want, note down the sha1 hash that is used to identify the commit. Next, run git checkout hash. After you are done, git checkout original_branch. This has the advantage of not moving the HEAD, it simply switches the working copy to a specific commit.

Update:

As mentioned below, not all implementations support this callback (i.e. platforms like iOS). In this case, as the docs say, you can set the validator explicitly:

handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;

This works too for .NET Core 2.2, 3.0 and 3.1

Old answer, with more control but may throw PlatformNotSupportedException:

You can override SSL cert check on a HTTP call with the a anonymous callback function like this

using (var httpClientHandler = new HttpClientHandler())
{
   httpClientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => { return true; };
   using (var client = new HttpClient(httpClientHandler))
   {
       // Make your request...
   }
}

Additionally, I suggest to use a factory pattern for HttpClient because it is a shared object that might no be disposed immediately and therefore connections will stay open.

Short Answer

If the goal is to create a grid with equal height rows, where the tallest cell in the grid sets the height for all rows, here's a quick and simple solution:

• Set the container to grid-auto-rows: 1fr

How it works

Grid Layout provides a unit for establishing flexible lengths in a grid container. This is the fr unit. It is designed to distribute free space in the container and is somewhat analogous to the flex-grow property in flexbox.

If you set all rows in a grid container to 1fr, let's say like this:

grid-auto-rows: 1fr;

... then all rows will be equal height.

It doesn't really make sense off-the-bat because fr is supposed to distribute free space. And if several rows have content with different heights, then when the space is distributed, some rows would be proportionally smaller and taller.

Except, buried deep in the grid spec is this little nugget:

7.2.3. Flexible Lengths: the fr unit

...

When the available space is infinite (which happens when the grid container’s width or height is indefinite), flex-sized (fr) grid tracks are sized to their contents while retaining their respective proportions.

The used size of each flex-sized grid track is computed by determining the max-content size of each flex-sized grid track and dividing that size by the respective flex factor to determine a “hypothetical 1fr size”.

The maximum of those is used as the resolved 1fr length (the flex fraction), which is then multiplied by each grid track’s flex factor to determine its final size.

So, if I'm reading this correctly, when dealing with a dynamically-sized grid (e.g., the height is indefinite), grid tracks (rows, in this case) are sized to their contents.

The height of each row is determined by the tallest (max-content) grid item.

The maximum height of those rows becomes the length of 1fr.

That's how 1fr creates equal height rows in a grid container.

Why flexbox isn't an option

As noted in the question, equal height rows are not possible with flexbox.

Flex items can be equal height on the same row, but not across multiple rows.

This behavior is defined in the flexbox spec:

6. Flex Lines

In a multi-line flex container, the cross size of each line is the minimum size necessary to contain the flex items on the line.

In other words, when there are multiple lines in a row-based flex container, the height of each line (the "cross size") is the minimum height necessary to contain the flex items on the line.

"Conflicts" mean "parallel evolutions of a same content". So if it goes "all to hell" during a merge, it means you have massive evolutions on the same set of files.

The reason why a rebase is then better than a merge is that:

• you rewrite your local commit history with the one of the master (and then reapply your work, resolving any conflict then)
• the final merge will certainly be a "fast forward" one, because it will have all the commit history of the master, plus only your changes to reapply.

I confirm that the correct workflow in that case (evolutions on common set of files) is rebase first, then merge.

However, that means that, if you push your local branch (for backup reason), that branch should not be pulled (or at least used) by anyone else (since the commit history will be rewritten by the successive rebase).

On that topic (rebase then merge workflow), barraponto mentions in the comments two interesting posts, both from randyfay.com:

• A Rebase Workflow for Git: reminds us to fetch first, rebase:

Using this technique, your work always goes on top of the public branch like a patch that is up-to-date with current HEAD.

(a similar technique exists for bazaar)

• Avoiding Git Disasters: A Gory Story: about the dangers of git push --force (instead of a git pull --rebase for instance)

2. Goto user's home directory by typing cd
3. Reload the profile with . .bash_profile

Since this still comes up as a first answer in Google I'll contribute possible solution.

Command taken from here suprisingly worked for me (Docker 1.13.1, Ubuntu 16.04) :

docker exec -u 0 <container-name> /bin/sh -c "echo '<ip> <name> >> /etc/hosts"

I had the same problem today, I solved it by installing recommended packages: libc6-dev-mipsel-cross libc6-dev-mipsel-cross, libc-dev-mipsel-cross

This worked:

sudo apt-get install libc6-dev-mipsel-cross

Try this. If I got any error on any file then I got error mail on my email id. Create two files index.php and checkErrorEmail.php and uploaded them to your server. Then load index.php with your browser.

Index.php

<?php
    include('checkErrorEmail.php');
    include('dereporting.php');
    $temp;
    echo 'hi '.$temp;
?>

checkErrorEmail.php

<?php

  define("ADMIN_EMAIL", "[email protected]");
  //define("LOG_FILE", "/my/home/errors.log");

  // Destination types
  define("DEST_EMAIL", "1");
  //define("DEST_LOGFILE", "3");

  /* Examples */

  // Send an e-mail to the administrator
  //error_log("Fix me!", DEST_EMAIL, ADMIN_EMAIL);

  // Write the error to our log file
  //error_log("Error", DEST_LOGFILE, LOG_FILE);

This is not CSS, but it is worth a mention:

jQuery UI Disable Selection:

$("your.selector").disableSelection();

position: absolute;
left: 50%;
top: 50%;
-webkit-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);

Explanation:

Give it an absolute positioning (the parent should have relative positioning). Then, the upper left corner is moved to the center. Because you don't know the width/height yet, you use css transform to translate the position relatively to the middle. translate(-50%, -50%) does reduce the x and y position of the upper left corner by 50% of width and height.

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

this code works for all browsers and all inputs.

$('#your_target_input').attr('value', '');

A simple way to fixe a 419 unknown status on your console is to put this script inside in your FORM. {{ csrf_field() }}

The code below has the following features:

1. Detection or attempted detection of UTF-7, UTF-8/16/32 (bom, no bom, little & big endian)
2. Falls back to the local default codepage if no Unicode encoding was found.
3. Detects (with high probability) unicode files with the BOM/signature missing
4. Searches for charset=xyz and encoding=xyz inside file to help determine encoding.
5. To save processing, you can 'taste' the file (definable number of bytes).
6. The encoding and decoded text file is returned.
7. Purely byte-based solution for efficiency

As others have said, no solution can be perfect (and certainly one can't easily differentiate between the various 8-bit extended ASCII encodings in use worldwide), but we can get 'good enough' especially if the developer also presents to the user a list of alternative encodings as shown here: What is the most common encoding of each language?

A full list of Encodings can be found using Encoding.GetEncodings();

// Function to detect the encoding for UTF-7, UTF-8/16/32 (bom, no bom, little
// & big endian), and local default codepage, and potentially other codepages.
// 'taster' = number of bytes to check of the file (to save processing). Higher
// value is slower, but more reliable (especially UTF-8 with special characters
// later on may appear to be ASCII initially). If taster = 0, then taster
// becomes the length of the file (for maximum reliability). 'text' is simply
// the string with the discovered encoding applied to the file.
public Encoding detectTextEncoding(string filename, out String text, int taster = 1000)
{
    byte[] b = File.ReadAllBytes(filename);

    //////////////// First check the low hanging fruit by checking if a
    //////////////// BOM/signature exists (sourced from http://www.unicode.org/faq/utf_bom.html#bom4)
    if (b.Length >= 4 && b[0] == 0x00 && b[1] == 0x00 && b[2] == 0xFE && b[3] == 0xFF) { text = Encoding.GetEncoding("utf-32BE").GetString(b, 4, b.Length - 4); return Encoding.GetEncoding("utf-32BE"); }  // UTF-32, big-endian 
    else if (b.Length >= 4 && b[0] == 0xFF && b[1] == 0xFE && b[2] == 0x00 && b[3] == 0x00) { text = Encoding.UTF32.GetString(b, 4, b.Length - 4); return Encoding.UTF32; }    // UTF-32, little-endian
    else if (b.Length >= 2 && b[0] == 0xFE && b[1] == 0xFF) { text = Encoding.BigEndianUnicode.GetString(b, 2, b.Length - 2); return Encoding.BigEndianUnicode; }     // UTF-16, big-endian
    else if (b.Length >= 2 && b[0] == 0xFF && b[1] == 0xFE) { text = Encoding.Unicode.GetString(b, 2, b.Length - 2); return Encoding.Unicode; }              // UTF-16, little-endian
    else if (b.Length >= 3 && b[0] == 0xEF && b[1] == 0xBB && b[2] == 0xBF) { text = Encoding.UTF8.GetString(b, 3, b.Length - 3); return Encoding.UTF8; } // UTF-8
    else if (b.Length >= 3 && b[0] == 0x2b && b[1] == 0x2f && b[2] == 0x76) { text = Encoding.UTF7.GetString(b,3,b.Length-3); return Encoding.UTF7; } // UTF-7


    //////////// If the code reaches here, no BOM/signature was found, so now
    //////////// we need to 'taste' the file to see if can manually discover
    //////////// the encoding. A high taster value is desired for UTF-8
    if (taster == 0 || taster > b.Length) taster = b.Length;    // Taster size can't be bigger than the filesize obviously.


    // Some text files are encoded in UTF8, but have no BOM/signature. Hence
    // the below manually checks for a UTF8 pattern. This code is based off
    // the top answer at: https://stackoverflow.com/questions/6555015/check-for-invalid-utf8

    {

Hence, there's no "utf8 = true;" code unlike the next three checks.
        if (b[i] >= 0xC2 && b[i] <= 0xDF && b[i + 1] >= 0x80 && b[i + 1] < 0xC0) { i += 2; utf8 = true; continue; }

        return Encoding.UTF8;
    }


    // The next check is a heuristic attempt to detect UTF-16 without a BOM.
    // We simply look for zeroes in odd or even byte places, and if a certain
    // threshold is reached, the code is 'probably' UF-16.          
    double threshold = 0.1; // proportion of chars step 2 which must be zeroed to be diagnosed as utf-16. 0.1 = 10%
    int count = 0;

    // Finally, a long shot - let's see if we can find "charset=xyz" or

As previously mentioned, the bundler version may be too high for your version of rails.

I ran into the same problem using Rails 3.0.1 which requires Bundler v1.0.0 - v1.0.22

Check your bundler version using: gem list bundler

If your bundler version is not within the appropriate range, I found this solution to work: rvm @global do gem uninstall bundler

Note: rvm is required for this solution... another case for why you should be using rvm in the first place.

--shell flag can also be used for javascript files

 mongo --shell /path/to/jsfile/test.js 

I started getting weird ConftestImportFailure: ImportError('No module named ... errors when I had accidentally added __init__.py file to my src directory (which was not supposed to be a Python package, just a container of all source).

$(document).ready(function () {
    $(".class").on('click', function () {
        $(".checkbox).prop('checked', true);
    });
});

var dateFormat = 'YYYY-DD-MM HH:mm:ss';
var testDateUtc = moment.utc('2015-01-30 10:00:00');
var localDate = testDateUtc.local();
console.log(localDate.format(dateFormat)); // 2015-30-01 02:00:00

1. Define your date format.
2. Create a moment object and set the UTC flag to true on the object.
3. Create a localized moment object converted from the original moment object.
4. Return a formatted string from the localized moment object.

See: http://momentjs.com/docs/#/manipulating/local/

I see 2 easy options:

• multiple background with a translucent single gradient over image
• huge inset shadow

gradient option:

html {
  min-height:100%;
  background:linear-gradient(0deg, rgba(255, 0, 150, 0.3), rgba(255, 0, 150, 0.3)), url(http://lorempixel.com/800/600/nature/2);
  background-size:cover;
}

shadow option:

html {
  min-height:100%;
  background:url(http://lorempixel.com/800/600/nature/2);
  background-size:cover;
  box-shadow:inset 0 0 0 2000px rgba(255, 0, 150, 0.3);
}

an old codepen of mine with few examples

a third option

• with background-blen-mode :

  The background-blend-mode CSS property sets how an element's background images should blend with each other and with the element's background color.

html {
  min-height:100%;
  background:url(http://lorempixel.com/800/600/nature/2) rgba(255, 0, 150, 0.3);
  background-size:cover;
  background-blend-mode: multiply;
}

This works for me

sed '/^all:/ s/$/ anotherthing/' file

The first part is a pattern to find and the second part is an ordinary sed's substitution using $ for the end of a line.

If you want to change the file during the process, use -i option

sed -i '/^all:/ s/$/ anotherthing/' file

Or you can redirect it to another file

sed '/^all:/ s/$/ anotherthing/' file > output

This is old post but I will share one my solution because noone mention here one problem before.

New email address can contain UTF-8 characters or special domain names like .live, .news etc.

Also I find that some email address can be on Cyrilic and on all cases standard regex or filter_var() will fail.

That's why I made an solution for it:

function valid_email($email) 
{
    if(is_array($email) || is_numeric($email) || is_bool($email) || is_float($email) || is_file($email) || is_dir($email) || is_int($email))
        return false;
    else
    {
        $email=trim(strtolower($email));
        if(filter_var($email, FILTER_VALIDATE_EMAIL)!==false) return $email;
        else
        {
            $pattern = '/^(?!(?:(?:\\x22?\\x5C[\\x00-\\x7E]\\x22?)|(?:\\x22?[^\\x5C\\x22]\\x22?)){255,})(?!(?:(?:\\x22?\\x5C[\\x00-\\x7E]\\x22?)|(?:\\x22?[^\\x5C\\x22]\\x22?)){65,}@)(?:(?:[\\x21\\x23-\\x27\\x2A\\x2B\\x2D\\x2F-\\x39\\x3D\\x3F\\x5E-\\x7E]+)|(?:\\x22(?:[\\x01-\\x08\\x0B\\x0C\\x0E-\\x1F\\x21\\x23-\\x5B\\x5D-\\x7F]|(?:\\x5C[\\x00-\\x7F]))*\\x22))(?:\\.(?:(?:[\\x21\\x23-\\x27\\x2A\\x2B\\x2D\\x2F-\\x39\\x3D\\x3F\\x5E-\\x7E]+)|(?:\\x22(?:[\\x01-\\x08\\x0B\\x0C\\x0E-\\x1F\\x21\\x23-\\x5B\\x5D-\\x7F]|(?:\\x5C[\\x00-\\x7F]))*\\x22)))*@(?:(?:(?!.*[^.]{64,})(?:(?:(?:xn--)?[a-z0-9]+(?:-+[a-z0-9]+)*\\.){1,126}){1,}(?:(?:[a-z][a-z0-9]*)|(?:(?:xn--)[a-z0-9]+))(?:-+[a-z0-9]+)*)|(?:\\[(?:(?:IPv6:(?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(?:(?!(?:.*[a-f0-9][:\\]]){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(?:(?:IPv6:(?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}:)|(?:(?!(?:.*[a-f0-9]:){5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}:)?)))?(?:(?:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\\.(?:(?:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))\\]))$/iD';
            return (preg_match($pattern, $email) === 1) ? $email : false;
        }
    }
}

This function work perfectly for all cases and email formats.

iOS 8 users and above, please include this in App delegate to make it work.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)])
    {
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
    }

    return YES;
}

And then adding this lines of code would help,

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    UILocalNotification *notification = [[UILocalNotification alloc]init];
    notification.repeatInterval = NSDayCalendarUnit;
    [notification setAlertBody:@"Hello world"];
    [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
    [notification setTimeZone:[NSTimeZone  defaultTimeZone]];
    [application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];

}

If you want to keep existing params and not expose yourself to XSS attacks, be sure to clean the params hash, leaving only the params that your app can be sending:

# inline
<%= link_to 'Link', params.slice(:sort).merge(per_page: 20) %>

If you use it in multiple places, clean the params in the controller:

# your_controller.rb
@params = params.slice(:sort, :per_page)

# view
<%= link_to 'Link', @params.merge(per_page: 20) %>

Read this article for better insight. Note: Numpy reports the shape of 3D arrays in the order layers, rows, columns.

It depends on your requirements. If IPet is simple enough, I would prefer to implement that. Otherwise, if PetBase implements a ton of functionality you don't want to duplicate, then have at it.

The downside to implementing a base class is the requirement to override (or new) existing methods. This makes them virtual methods which means you have to be careful about how you use the object instance.

Lastly, the single inheritance of .NET kills me. A naive example: Say you're making a user control, so you inherit UserControl. But, now you're locked out of also inheriting PetBase. This forces you to reorganize, such as to make a PetBase class member, instead.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

What kind of authentication are you using? If it's Forms authentication, then at best, you'll have to find the .ASPXAUTH cookie and pass it in the WebClient request.

At worst, it won't work.

There is one rather sneaky trick not mentioned here so far. We assume that you have no extra way to store data, but that is not strictly true.

One way around your problem is to do the following horrible thing, which should not be attempted by anyone under any circumstances: Use the network traffic to store data. And no, I don't mean NAS.

You can sort the numbers with only a few bytes of RAM in the following way:

• First take 2 variables: COUNTER and VALUE.
• First set all registers to 0;
• Every time you receive an integer I, increment COUNTER and set VALUE to max(VALUE, I);
• Then send an ICMP echo request packet with data set to I to the router. Erase I and repeat.
• Every time you receive the returned ICMP packet, you simply extract the integer and send it back out again in another echo request. This produces a huge number of ICMP requests scuttling backward and forward containing the integers.

Once COUNTER reaches 1000000, you have all of the values stored in the incessant stream of ICMP requests, and VALUE now contains the maximum integer. Pick some threshold T >> 1000000. Set COUNTER to zero. Every time you receive an ICMP packet, increment COUNTER and send the contained integer I back out in another echo request, unless I=VALUE, in which case transmit it to the destination for the sorted integers. Once COUNTER=T, decrement VALUE by 1, reset COUNTER to zero and repeat. Once VALUE reaches zero you should have transmitted all integers in order from largest to smallest to the destination, and have only used about 47 bits of RAM for the two persistent variables (and whatever small amount you need for the temporary values).

I know this is horrible, and I know there can be all sorts of practical issues, but I thought it might give some of you a laugh or at least horrify you.
