Perhaps manager app does not exist look if you the manager application is on $APACHE_HOME/server/webapps directory. on this directory you must have : docs,examples, host-manager,manager, ROOT.

As far as your question goes: no, if activating from .ini is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap, yum install php-soap). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).

In general, the double-dash --switches are designed to be used when recompiling PHP from scratch.

You would download the PHP source package (as a compressed .tgz tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script

./configure --prefix ...

The configure command used by your PHP may be shown with phpinfo(). Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap will then enable SOAP in addition to everything else.

That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype, gd, libjpeg, XML, expat, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg installed might not be enough, and you might need libjpeg-dev also).

I have to keep a separate virtual machine with everything installed for my recompilation purposes.

The clickAndWait command doesn't get converted when you choose the Webdriver format in the Selenium IDE. Here is the workaround. Add the wait line below. Realistically, the problem was the click or event that happened before this one--line 1 in my C# code. But really, just make sure you have a WaitForElement before any action where you're referencing a "By" object.

HTML code:

<a href="http://www.google.com">xxxxx</a>

C#/NUnit code:

driver.FindElement(By.LinkText("z")).Click;
driver.WaitForElement(By.LinkText("xxxxx"));
driver.FindElement(By.LinkText("xxxxx")).Click();

The original post might have been true back in 2009, but now it is actually incorrect now, and no linking is even required for the stylesheet as I see mentioned in some of the other responses. Rails will now do this for you by default.

• Place any new sheet .css (or other) in app/assets/stylesheets
• Test your server with rails-root/scripts/rails server and you'll see the link is added by rails itself.

You can test this with a path in your browser like testserverpath:3000/assets/filename_to_test.css?body=1

The most common way I have seen to encode this is with a character class whose members form a partition of the set of all possible characters.

Usually people write that as [\s\S] (whitespace or non-whitespace), though [\w\W], [\d\D], etc. would all work.

S3 is an object storage, it doesn't have real directory structure. The "/" is rather cosmetic. One reason that people want to have a directory structure, because they can maintain/prune/add a tree to the application. For S3, you treat such structure as sort of index or search tag.

To manipulate object in S3, you need boto3.client or boto3.resource, e.g. To list all object

import boto3 
s3 = boto3.client("s3")
all_objects = s3.list_objects(Bucket = 'bucket-name') 

http://boto3.readthedocs.org/en/latest/reference/services/s3.html#S3.Client.list_objects

In fact, if the s3 object name is stored using '/' separator. The more recent version of list_objects (list_objects_v2) allows you to limit the response to keys that begin with the specified prefix.

To limit the items to items under certain sub-folders:

    import boto3 
    s3 = boto3.client("s3")
    response = s3.list_objects_v2(
            Bucket=BUCKET,
            Prefix ='DIR1/DIR2',
            MaxKeys=100 )

Documentation

Another option is using python os.path function to extract the folder prefix. Problem is that this will require listing objects from undesired directories.

import os
s3_key = 'first-level/1456753904534/part-00014'
filename = os.path.basename(s3_key) 
foldername = os.path.dirname(s3_key)

# if you are not using conventional delimiter like '#' 
s3_key = 'first-level#1456753904534#part-00014
filename = s3_key.split("#")[-1]

A reminder about boto3 : boto3.resource is a nice high level API. There are pros and cons using boto3.client vs boto3.resource. If you develop internal shared library, using boto3.resource will give you a blackbox layer over the resources used.

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

Try it:

is_even = lambda x: True if x % 2 == 0 else False
print(is_even(10))
print(is_even(11))

Out:

True
False

The following supposedly gets you CPU and RAM. See ManagementFactory for more details.

import java.lang.management.ManagementFactory;
import java.lang.management.OperatingSystemMXBean;
import java.lang.reflect.Method;
import java.lang.reflect.Modifier;

private static void printUsage() {
  OperatingSystemMXBean operatingSystemMXBean = ManagementFactory.getOperatingSystemMXBean();
  for (Method method : operatingSystemMXBean.getClass().getDeclaredMethods()) {
    method.setAccessible(true);
    if (method.getName().startsWith("get")
        && Modifier.isPublic(method.getModifiers())) {
            Object value;
        try {
            value = method.invoke(operatingSystemMXBean);
        } catch (Exception e) {
            value = e;
        } // try
        System.out.println(method.getName() + " = " + value);
    } // if
  } // for
}

you can use grep, then take lines in jumps:
grep -A1 'blah' logfile | awk 'NR%3==2'

you can also take n lines after match, for example:
seq 100 | grep -A3 .2 | awk 'NR%5==4'
15
25
35
45
55
65
75
85
95
explanation -
here we want to grep all lines that are *2 and take 3 lines after it, which is *5.
seq 100 | grep -A3 .2 will give you:
12
13
14
15
--
22
23
24
25
--
...
the number in the modulo (NR%5) is the added rows by grep (here it's 3 by the flag -A3), +2 extra lines because you have current matching line and also the -- line that the grep is adding.

You can install the mail package in Ubuntu with below command.

For Ubuntu -:

$ sudo apt-get install -y mailutils

For CentOs-:

$ sudo yum install -y mailx

Test Mail command-:

$ echo "Mail test" | mail -s "Subject" [email protected]

Arrays.asList(array);    

Example:

 List<String> stooges = Arrays.asList("Larry", "Moe", "Curly");

See Arrays.asList class documentation.

Sounds bad?

 pkill `pidof myprocess`

example:

# kill all java processes
pkill `pidof java`

Git- Git is a version control software that you install on your local system. For an individual working on a project alone, Git proves to be excellent software.

GitHub- As mentioned earlier, Git is a version control system that tracks code changes, while GitHub is a web-based Git version control repository hosting service. It provides all of the distributed version control and source code management (SCM) functionalities of Git while topping it with a few of its own features.

@amal. This code will match your requirement. Only letter and space in between will be allow, no number. The text begin with any letter and could have space in between only. "^" denotes the beginning of the line and "$" denotes end of the line.

public static boolean validateLetters(String txt) {

    String regx = "^[a-zA-Z ]+$";
    Pattern pattern = Pattern.compile(regx,Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(txt);
    return matcher.find();

}

Basically, flush() cleans out your RAM buffer, its real power is that it lets you continue to write to it afterwards - but it shouldn't be thought of as the best/safest write to file feature. It's flushing your RAM for more data to come, that is all. If you want to ensure data gets written to file safely then use close() instead.

Now to answer the question that perhaps you should have asked, like "I'm getting 100 floats form somewhere; do I need to put them in an array or list before I find the minimum?"

Answer: No, if somewhere is a iterable, instead of doing this:

temp = []
for x in somewhere:
   temp.append(x)
answer = min(temp)

you can do this:

answer = min(somewhere)

Example:

answer = min(float(line) for line in open('floats.txt'))

While checking null or Empty value for a column, I noticed that there are some support concerns in various Databases.

Every Database doesn't support TRIM method.

Below is the matrix just to understand the supported methods by different databases.

The TRIM function in SQL is used to remove specified prefix or suffix from a string. The most common pattern being removed is white spaces. This function is called differently in different databases:

• MySQL: TRIM(), RTRIM(), LTRIM()
• Oracle: RTRIM(), LTRIM()
• SQL Server: TRIM(), RTRIM(), LTRIM()

How to Check Empty/Null/Whitespace :-

Below are two different ways according to different Databases-

The syntax for these trim functions are:

1. Use of Trim to check-

   SELECT FirstName FROM UserDetails WHERE TRIM(LastName) IS NULL

2. Use of LTRIM & RTRIM to check-

   SELECT FirstName FROM UserDetails WHERE LTRIM(RTRIM(LastName)) IS NULL

Above both ways provide same result just use based on your DataBase support. It Just returns the FirstName from UserDetails table if it has an empty LastName

Hoping this will help others too :)

Good answer from @unwind. It however can't handle extreme negative number (throwing OverflowError).

My improvement:

def sigmoid(x):
    try:
        res = 1 / (1 + math.exp(-x))
    except OverflowError:
        res = 0.0
    return res

you can simply use the get/set method for set the value

$("#select").select2("val"); //get the value
$("#select").select2("val", "CA"); //set the value

or you can do this:

$('#select').val("E").change(); // you must enter the Value instead of the string

Or without the year:

DateTime.Now.ToString("M/dd")

There is an isConnected function in BluetoothDevice system API in https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/BluetoothDevice.java

If you want to know if the a bounded(paired) device is currently connected or not, the following function works fine for me:

public static boolean isConnected(BluetoothDevice device) {
    try {
        Method m = device.getClass().getMethod("isConnected", (Class[]) null);
        boolean connected = (boolean) m.invoke(device, (Object[]) null);
        return connected;
    } catch (Exception e) {
        throw new IllegalStateException(e);
    }
}

I was facing the same issue, so I replaced the ".git" folder with a backed up version and it still wasn't working because .gitconfig file was corrupted. The BSOD on my laptop corrupted it. I replaced it with the following code and sourcetree restored all my repositories.

[user]
name = *your username*
email = *your email address*
[core]
autocrlf = true
excludesfile = C:\\Users\\*user name*\\Documents\\gitignore_global.txt

I don't know if this will help anybody, but this is just another solution that worked for me.

Also You Can Use Server.Execute

Previous answer didn't work for me.

But this worked perfectly. Convert Data URI to File then append to FormData

If all of the matrices are going to be the same size (i.e. 500x800), then you can just make a 3D array:

nUnknown;  % The number of unknown arrays
myArray = zeros(500,800,nUnknown);

To access one array, you would use the following syntax:

subMatrix = myArray(:,:,3);  % Gets the third matrix

You can add more matrices to myArray in a couple of ways:

myArray = cat(3,myArray,zeros(500,800));
% OR
myArray(:,:,nUnknown+1) = zeros(500,800);

If each matrix is not going to be the same size, you would need to use cell arrays like Hosam suggested.

EDIT: I missed the part about running out of memory. I'm guessing your nUnknown is fairly large. You may have to switch the data type of the matrices (single or even a uintXX type if you are using integers). You can do this in the call to zeros:

myArray = zeros(500,800,nUnknown,'single');

Change Column Name/Type/Position/Comment:

ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name column_type [COMMENT col_comment] [FIRST|AFTER column_name]

Example:

CREATE TABLE test_change (a int, b int, c int);

// will change column a's name to a1
ALTER TABLE test_change CHANGE a a1 INT;

Based on this blog, one could share a docker image without a docker registry by executing:

docker save --output latestversion-1.0.0.tar dockerregistry/latestversion:1.0.0

Once this command has been completed, one could copy the image to a server and import it as follows:

docker load --input latestversion-1.0.0.tar

If you don't want to use any JPA provider such as OpenJPA or Hibernate, you can just give Apache DbUtils a try.

http://commons.apache.org/proper/commons-dbutils/examples.html

Then your code will look like this:

QueryRunner run = new QueryRunner(dataSource);

// Use the BeanListHandler implementation to convert all
// ResultSet rows into a List of Person JavaBeans.
ResultSetHandler<List<Person>> h = new BeanListHandler<Person>(Person.class);

// Execute the SQL statement and return the results in a List of
// Person objects generated by the BeanListHandler.
List<Person> persons = run.query("SELECT * FROM Person", h);

the time signal is not built into network antennas: you have to use the NTP protocol in order to retrieve the time on a ntp server. there are plenty of ntp clients, available as standalone executables or libraries.

the gps signal does indeed include a precise time signal, which is available with any "fix".

however, if nor the network, nor the gps are available, your only choice is to resort on the time of the phone... your best solution would be to use a system wide setting to synchronize automatically the phone time to the gps or ntp time, then always use the time of the phone.

note that the phone time, if synchronized regularly, should not differ much from the gps or ntp time. also note that forcing a user to synchronize its time may be intrusive, you 'd better ask your user if he accepts synchronizing. at last, are you sure you absolutely need a time that precise ?

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

For me -D_GLIBCXX_USE_CXX11_ABI=0 didn't help.

It works after I linked to C++ libs version instead of gnustl.

localStorage.clear();

or

window.localStorage.clear();

to clear particular item

window.localStorage.removeItem("item_name");

To remove particular value by id :

var item_detail = JSON.parse(localStorage.getItem("key_name")) || [];           
            $.each(item_detail, function(index, obj){
                if (key_id == data('key')) {
                    item_detail.splice(index,1);
                    localStorage["key_name"] = JSON.stringify(item_detail);
                    return false;
                }
            });

On Windows in PowerShell, use:

Invoke-Expression $(aws ecr get-login --no-include-email)

I often do this way. Try this way :

ps aux | grep script_Name

Here, script_Name could be any script/file run by nohup. This command gets you a process ID. Then use this command below to kill the script running on nohup.

kill -9 1787 787

Here, 1787 and 787 are Process ID as mentioned in the question as an example. This should do what was intended in the question.

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings.

$s = '1234.13';
$double = bcadd($s,'0',2);

PHP: bcadd

I modify it in the .env APP_TIMEZONE.

For Colombia: APP_TIMEZONE = America / Bogota also for paris like this: APP_TIMEZONE = Europe / Paris

In order to avoid having to fully specify the git push command you could alternatively modify your git config file:

[remote "gerrit"]
    url = https://your.gerrit.repo:44444/repo
    fetch = +refs/heads/master:refs/remotes/origin/master
    push = refs/heads/master:refs/for/master

Now you can simply:

git fetch gerrit
git push gerrit

This is according to Gerrit

Given numpy, you could use linspace:

Including the right endpoint (5):

In [46]: import numpy as np
In [47]: np.linspace(0,5,10)
Out[47]: 
array([ 0.        ,  0.55555556,  1.11111111,  1.66666667,  2.22222222,
        2.77777778,  3.33333333,  3.88888889,  4.44444444,  5.        ])

Excluding the right endpoint:

In [48]: np.linspace(0,5,10,endpoint=False)
Out[48]: array([ 0. ,  0.5,  1. ,  1.5,  2. ,  2.5,  3. ,  3.5,  4. ,  4.5])

You have a few options:

1. Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.

2. Read the submit button values from the POST data. You can tell which submit button was clicked: How can I build multiple submit buttons django form?

When you declare

public static <T> void foo(List<T>... bar) the compiler converts it to

public static <T> void foo(List<T>[] bar) then to

public static void foo(List[] bar)

The danger then arises that you'll mistakenly assign incorrect values into the list and the compiler will not trigger any error. For example, if T is a String then the following code will compile without error but will fail at runtime:

// First, strip away the array type (arrays allow this kind of upcasting)
Object[] objectArray = bar;

// Next, insert an element with an incorrect type into the array
objectArray[0] = Arrays.asList(new Integer(42));

// Finally, try accessing the original array. A runtime error will occur
// (ClassCastException due to a casting from Integer to String)
T firstElement = bar[0].get(0);

If you reviewed the method to ensure that it doesn't contain such vulnerabilities then you can annotate it with @SafeVarargs to suppress the warning. For interfaces, use @SuppressWarnings("unchecked").

If you get this error message:

Varargs method could cause heap pollution from non-reifiable varargs parameter

and you are sure that your usage is safe then you should use @SuppressWarnings("varargs") instead. See Is @SafeVarargs an appropriate annotation for this method? and https://stackoverflow.com/a/14252221/14731 for a nice explanation of this second kind of error.

The short answer: I've found it very difficult to maintain a Maven build system, and I would like to switch to Gradle as soon as I can.

I've been working with Maven for over four years. I would call myself an expert on build systems because in the last (at least) five companies I've been in, I've done major renovations on the build/deploy infrastructure.

Some of the lessons I've learned:

• Most developers tend not to spend a lot of time thinking about build systems; as a result, the build turns into a spaghetti mess of hacks, but they do appreciate it when that mess is cleaned up and rationalized.
• In dealing with complexity, I would rather have a transparent system that exposes the complexity (like Ant) than one that tries to make complex things simple by imposing rigid restrictions, like Maven. Think of Linux vs. Windows.
• Maven has a lot of holes in functionality which require byzantine workarounds. This leads to POM files that are incomprehensible and unmaintainable.
• Ant is super-flexible and understandable, but Ant files can get pretty big too, because it's so low-level.
• For any significant project, developers have to create their own build/deploy structure beyond what the tool provides; the suitability of the structure to the project has a lot to do with how easy it is to maintain. The best tools will support you in creating a structure and not fight you.

I've looked into Gradle a bit and it looks like it has the potential to be the best of both worlds, allowing a mix of declarative and procedural build description.

I was wondering if it is possible to execute something like this using JDBC.

"SELECT FROM * TABLE;INSERT INTO TABLE;"

Yes it is possible. There are two ways, as far as I know. They are

1. By setting database connection property to allow multiple queries, separated by a semi-colon by default.
2. By calling a stored procedure that returns cursors implicit.

Following examples demonstrate the above two possibilities.

Example 1: ( To allow multiple queries ):

While sending a connection request, you need to append a connection property allowMultiQueries=true to the database url. This is additional connection property to those if already exists some, like autoReConnect=true, etc.. Acceptable values for allowMultiQueries property are true, false, yes, and no. Any other value is rejected at runtime with an SQLException.

String dbUrl = "jdbc:mysql:///test?allowMultiQueries=true";  

Unless such instruction is passed, an SQLException is thrown.

You have to use execute( String sql ) or its other variants to fetch results of the query execution.

boolean hasMoreResultSets = stmt.execute( multiQuerySqlString );

To iterate through and process results you require following steps:

READING_QUERY_RESULTS: // label  
    while ( hasMoreResultSets || stmt.getUpdateCount() != -1 ) {  
        if ( hasMoreResultSets ) {  
            Resultset rs = stmt.getResultSet();
            // handle your rs here
        } // if has rs
        else { // if ddl/dml/...
            int queryResult = stmt.getUpdateCount();  
            if ( queryResult == -1 ) { // no more queries processed  
                break READING_QUERY_RESULTS;  
            } // no more queries processed  
            // handle success, failure, generated keys, etc here
        } // if ddl/dml/...

        // check to continue in the loop  
        hasMoreResultSets = stmt.getMoreResults();  
    } // while results

Example 2: Steps to follow:

1. Create a procedure with one or more select, and DML queries.
2. Call it from java using CallableStatement.
3. You can capture multiple ResultSets executed in procedure.
   DML results can't be captured but can issue another select
   to find how the rows are affected in the table.

Sample table and procedure:

mysql> create table tbl_mq( i int not null auto_increment, name varchar(10), primary key (i) );
Query OK, 0 rows affected (0.16 sec)

mysql> delimiter //
mysql> create procedure multi_query()
    -> begin
    ->  select count(*) as name_count from tbl_mq;
    ->  insert into tbl_mq( names ) values ( 'ravi' );
    ->  select last_insert_id();
    ->  select * from tbl_mq;
    -> end;
    -> //
Query OK, 0 rows affected (0.02 sec)
mysql> delimiter ;
mysql> call multi_query();
+------------+
| name_count |
+------------+
|          0 |
+------------+
1 row in set (0.00 sec)

+------------------+
| last_insert_id() |
+------------------+
|                3 |
+------------------+
1 row in set (0.00 sec)

+---+------+
| i | name |
+---+------+
| 1 | ravi |
+---+------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Call Procedure from Java:

CallableStatement cstmt = con.prepareCall( "call multi_query()" );  
boolean hasMoreResultSets = cstmt.execute();  
READING_QUERY_RESULTS:  
    while ( hasMoreResultSets ) {  
        Resultset rs = stmt.getResultSet();
        // handle your rs here
    } // while has more rs

Adding to Santosh :

You can load React by

import React from 'react'

Another way of doing so is:

while i<len(your_list):
    if #condition :
        del your_list[i]
    else:
        i+=1

So, you delete the elements side by side while checking

pathinfo is cool but your code can be improved:

$filename = $_FILES['video_file']['name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);
$allowed = array('jpg','png','gif');
if( ! in_array( $ext, $allowed ) ) {echo 'error';}

Of course simply checking the extension of the filename would not guarantee the file type as a valid image. You may consider using a function like getimagesize to validate uploaded image files.

I believe that before we started using ES6, an approach with a single var declaration was neither good nor bad (in case if you have linters and 'use strict'. It was really a taste preference. But now things changed for me. These are my thoughts in favour of multiline declaration:

1. Now we have two new kinds of variables, and var became obsolete. It is good practice to use const everywhere until you really need let. So quite often your code will contain variable declarations with assignment in the middle of the code, and because of block scoping you quite often will move variables between blocks in case of small changes. I think that it is more convenient to do that with multiline declarations.

2. ES6 syntax became more diverse, we got destructors, template strings, arrow functions and optional assignments. When you heavily use all those features with single variable declarations, it hurts readability.

You could put \s* inbetween every character in your search string so if you were looking for cat you would use c\s*a\s*t\s*s\s*s

It's long but you could build the string dynamically of course.

You can see it working here: http://www.rubular.com/r/zzWwvppSpE

You can do this if you use an <a> tag instead of a button. I know it's not exactly what you asked for, but it might give you some other options if you cannot find a solution to this:

Borrowing from a demo from another answer here I produced this:

a {_x000D_
  display: block;_x000D_
  font-size: 18px;_x000D_
  border: 2px solid gray;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  text-align: center;_x000D_
  line-height: 100px;_x000D_
}_x000D_
_x000D_
a:active {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid green;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
a:target {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid red;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}

<a id="btn" href="#btn">Demo</a>

Notice the use of :target; this will be the style applied when the element is targeted via the hash. Which also means your HTML will need to be this: <a id="btn" href="#btn">Demo</a> a link targeting itself. and the demo http://jsfiddle.net/rlemon/Awdq5/4/

Thanks to @BenjaminGruenbaum here is a better demo: http://jsfiddle.net/agzVt/

_{Also, as a footnote: this should really be done with JavaScript and applying / removing CSS classes from the element. It would be much less convoluted.}

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

PHP extensions for Ubuntu 18.04 LTS (Bionic)

PHP extensions for Ubuntu 16.04 LTS (Xenial)

network solutions offers the advice to put a php.ini in the cgi-bin to enable mod_rewrite

If you can use repeated letters, you can use the * operator:

>>> 'a'*5

'aaaaa'

Please follow these step, I hope your key working properly:

1. Step 1 You will need OpenSSL. You can download the binary from openssl-for-windows project on Google Code.

2. Step 2 Unzip the folder, then copy the path to the bin folder to the clipboard.

   For example, if the file is unzipped to the location C:\Users\gaurav\openssl-0.9.8k_WIN32, then copy the path C:\Users\gaurav\openssl-0.9.8k_WIN32\bin.

3. Step 3 Add the path to your system environment path. After your PATH environment variable is set, open the cmd and type this command:

   C:\>keytool -exportcert -alias androiddebugkey -keystore [path to debug.keystore] | openssl sha1 -binary | openssl base64
   

   Type your password when prompted. If the command works, then you will be shown a key.

Looking at the source code of the page I took the reCaptcha part and changed the code a bit. Here's the code:

HTML:

<div class="tabs">
    <ul class="product-tabs">
        <li id="product_tabs_new" class="active"><a href="#">Detailed Description</a></li>
        <li id="product_tabs_what"><a href="#">Request Information</a></li>
        <li id="product_tabs_wha"><a href="#">Make Offer</a></li>
    </ul>
</div>

<div class="tab_content">
    <li class="wide">
        <div id="product_tabs_new_contents">
            <?php $_description = $this->getProduct()->getDescription(); ?>
            <?php if ($_description): ?>
                <div class="std">
                    <h2><?php echo $this->__('Details') ?></h2>
                    <?php echo $this->helper('catalog/output')->productAttribute($this->getProduct(), $_description, 'description') ?>
                </div>
            <?php endif; ?>
        </div>
    </li>

    <li class="wide">
        <label for="recaptcha">Captcha</label>
        <div id="more_info_recaptcha_box" class="input-box more_info_recaptcha_box"></div>
    </li>

    <li class="wide">
        <label for="recaptcha">Captcha</label>
        <div id="make_offer_recaptcha_box" class="input-box make_offer_recaptcha_box"></div>
    </li>
</div>

jQuery:

<script type="text/javascript" src="http://www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>
<script type="text/javascript">
    jQuery(document).ready(function() {
        var recapExist = false;
      // Create our reCaptcha as needed
        jQuery('#product_tabs_what').click(function() {
            if(recapExist == false) {
                Recaptcha.create("<?php echo $publickey; ?>", "more_info_recaptcha_box");
                recapExist = "make_offer_recaptcha_box";
            } else if(recapExist == 'more_info_recaptcha_box') {
                Recaptcha.destroy(); // Don't really need this, but it's the proper way
                Recaptcha.create("<?php echo $publickey; ?>", "more_info_recaptcha_box");
                recapExist = "make_offer_recaptcha_box";
            }
        });
        jQuery('#product_tabs_wha').click(function() {
            if(recapExist == false) {
                Recaptcha.create("<?php echo $publickey; ?>", "make_offer_recaptcha_box");
                recapExist = "more_info_recaptcha_box";
            } else if(recapExist == 'make_offer_recaptcha_box') {
                Recaptcha.destroy(); // Don't really need this, but it's the proper way (I think :)
                Recaptcha.create("<?php echo $publickey; ?>", "make_offer_recaptcha_box");
                recapExist = "more_info_recaptcha_box";
            }
        });
    });
</script>

I am using here simple javascript tab functionality. So, didn't included that code.

When user would click on "Request Information" (#product_tabs_what) then JS will check if recapExist is false or has some value. If it has a value then this will call Recaptcha.destroy(); to destroy the old loaded reCaptcha and will recreate it for this tab. Otherwise this will just create a reCaptcha and will place into the #more_info_recaptcha_box div. Same as for "Make Offer" #product_tabs_wha tab.

You want to get an element from an empty array. That's why the Size: 0 from the exception

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

So you cant do lstpp.get(0) until you fill the array.

Try this:

Dim text As String = ""
Dim files() As String = IO.Directory.GetFiles(sFolder)

For Each sFile As String In files
    text &= IO.File.ReadAllText(sFile)

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

Keep in mind that you have to exactly specify your path to your language.JSON like this:

language: {
    url: '/mywebsite/js/localisation/German.json'
}

For internal gridlines, use the tag: td For external gridlines, use the tag: table

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

check field execution_status

0 - Returns only those jobs that are not idle or suspended.
1 - Executing.
2 - Waiting for thread.
3 - Between retries.
4 - Idle.
5 - Suspended.
7 - Performing completion actions.

If you need the result of execution, check the field last_run_outcome

0 = Failed
1 = Succeeded
3 = Canceled
5 = Unknown

Statically typed languages type-check at compile time and the type can NOT change. (Don't get cute with type-casting comments, a new variable/reference is created).

Dynamically typed languages type-check at run-time and the type of an variable CAN be changed at run-time.

1. --save-dev (only used in the development, not in production)

2. --save (production dependencies)

3. --global or -g (used globally i.e can be used anywhere in our local system)

Found this while Googling. The second post makes a point about the different phases of JSF, which might be causing your error message to become lost. Also, try null in place of "newPassword" because you do not have any object with the id newPassword.

Another scenario where you might see this is when you are attempting to connect to another SQL server from an SSMS session that was already logged-in while you changed your password. Sequence of events might go something like:

1. RDP to Server-A (your SQL Server), open SSMS and login
2. RDP to Server-B in the same domain and change your password
3. Return to RDP session on Server-A and via SSMS attempt to add another DB into an existing AlwaysOn availability group. When connecting to replicas you get "untrusted domain"-login-error

To resolve, simply logoff and log back in

You could wrap the textbox and button in an ASP:Panel, and set the DefaultButton property of the Panel to the Id of your Submit button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="SubmitButton">
    <asp:TextBox ID="TextBox1" runat="server" />
    <asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" />
</asp:Panel>

Now anytime the focus is within the Panel, the 'SubmitButton_Click' event will fire when enter is pressed.

This solved me the problem.

For those stuck on windows (version >= server 2012 or win 8)and python 2.7,

import ctypes

class FILETIME(ctypes.Structure):
    _fields_ = [("dwLowDateTime", ctypes.c_uint),
                ("dwHighDateTime", ctypes.c_uint)]

def time():
    """Accurate version of time.time() for windows, return UTC time in term of seconds since 01/01/1601
"""
    file_time = FILETIME()
    ctypes.windll.kernel32.GetSystemTimePreciseAsFileTime(ctypes.byref(file_time))
    return (file_time.dwLowDateTime + (file_time.dwHighDateTime << 32)) / 1.0e7

GetSystemTimePreciseAsFileTime function

To see what the problem is, when you get the cryptic error 0 go to ... | More Tools | Developer Tools (Ctrl+Shift+I) in Chrome (on the page giving the error)

Read the red text in the log to get the true error message. If there is too much in there, right-click and Clear Console, then do your last request again.

My first problem was, I was passing in Authorization headers to my own cross-domain web service for the browser for the first time.

I already had:

Access-Control-Allow-Origin: *

But not:

Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Headers: Authorization

in the response header of my web service.

After I added that, my error zero was gone from my own web server, as well as when running the index.html file locally without a web server, but was still giving errors in code pen.

Back to ... | More Tools | Developer Tools while getting the error in codepen, and there is clearly explained: codepen uses https, so I cannot make calls to http, as the security is lower.

I need to therefore host my web service on https.

Knowing how to get the true error message - priceless!

The command is this:

mysqlcheck -u root -p --auto-repair --check --all-databases

You must supply the password when asked,

or you can run this one but it's not recommended because the password is written in clear text:

mysqlcheck -u root --password=THEPASSWORD --auto-repair --check --all-databases

In my case the image file had just been written to and needed to be flushed before opening, like so:

This is system dependent but often -1. See here

You might also find it useful to know generally what these data types are used for:

• :string - is for small data types such as a title. (Should you choose string or text?)
• :text - is for longer pieces of textual data, such as a paragraph of information
• :binary - is for storing data such as images, audio, or movies.
• :boolean - is for storing true or false values.
• :date - store only the date
• :datetime - store the date and time into a column.
• :time - is for time only
• :timestamp - for storing date and time into a column.(What's the difference between datetime and timestamp?)
• :decimal - is for decimals (example of how to use decimals).
• :float - is for decimals. (What's the difference between decimal and float?)
• :integer - is for whole numbers.
• :primary_key - unique key that can uniquely identify each row in a table

There's also references used to create associations. But, I'm not sure this is an actual data type.

New Rails 4 datatypes available in PostgreSQL:

• :hstore - storing key/value pairs within a single value (learn more about this new data type)
• :array - an arrangement of numbers or strings in a particular row (learn more about it and see examples)
• :cidr_address - used for IPv4 or IPv6 host addresses
• :inet_address - used for IPv4 or IPv6 host addresses, same as cidr_address but it also accepts values with nonzero bits to the right of the netmask
• :mac_address - used for MAC host addresses

Learn more about the address datatypes here and here.

On the selected answer I see that when initially the page is loaded the selection of first option is prior fixed and therefore gives the option of all the categories in selection 2. You can avoid that by adding the first option as the following in both the select tag:- <option value="none" selected disabled hidden>Select an Option</option>

<select name="select1" id="select1">
<option value="none" selected disabled hidden>Select an Option</option>
<option value="1">Fruit</option>
  <option value="2">Animal</option>
  <option value="3">Bird</option>
  <option value="4">Car</option>
</select>


<select name="select2" id="select2">
<option value="none" selected disabled hidden>Select an Option</option>
  <option value="1">Banana</option>
  <option value="1">Apple</option>
  <option value="1">Orange</option>
  <option value="2">Wolf</option>
  <option value="2">Fox</option>
  <option value="2">Bear</option>
  <option value="3">Eagle</option>
  <option value="3">Hawk</option>
  <option value="4">BWM<option>

Make the sql mode non strict

if using laravel go to config->database, the go to mysql settings and make the strict mode false

It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.

Suppose your select has 10 option, then fixed size=9.

Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.

Here is your modified code from jsfiddle:

<select size="5" style="width:100px;">
 <option>1</option>
 <option>2</option>
 <option>3</option>
 <option>4</option>
 <option>5</option>
 <option>6</option>
</select>

this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).

Here is your desired result. I think this will help you:

  .wrapper{
    border: 1px dashed red;
    height: 150px;
    overflow-x: hidden;
    overflow-y: scroll;

So it seems that there is no way to reattach a stale detached entity in JPA.

merge() will push the stale state to the DB, and overwrite any intervening updates.

refresh() cannot be called on a detached entity.

lock() cannot be called on a detached entity, and even if it could, and it did reattach the entity, calling 'lock' with argument 'LockMode.NONE' implying that you are locking, but not locking, is the most counterintuitive piece of API design I've ever seen.

So you are stuck. There's an detach() method, but no attach() or reattach(). An obvious step in the object lifecycle is not available to you.

Judging by the number of similar questions about JPA, it seems that even if JPA does claim to have a coherent model, it most certainly does not match the mental model of most programmers, who have been cursed to waste many hours trying understand how to get JPA to do the simplest things, and end up with cache management code all over their applications.

It seems the only way to do it is discard your stale detached entity and do a find query with the same id, that will hit the L2 or the DB.

You can get the maximum like this:

>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]]
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]].max(axis=1)
0    1
1    8
2    3

and so:

>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

If you know that "A" and "B" are the only columns, you could even get away with

>>> df["C"] = df.max(axis=1)

And you could use .apply(max, axis=1) too, I guess.

Try

//re:*[. ='match']

byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
    fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}
ImageConverter imageConverter = new System.Drawing.ImageConverter();
System.Drawing.Image image = imageConverter.ConvertFrom(fileData) as System.Drawing.Image;
image.Save(imageFullPath, System.Drawing.Imaging.ImageFormat.Jpeg);

Just set the domain and path attributes on your cookie, like:

<script type="text/javascript">
var cookieName = 'HelloWorld';
var cookieValue = 'HelloWorld';
var myDate = new Date();
myDate.setMonth(myDate.getMonth() + 12);
document.cookie = cookieName +"=" + cookieValue + ";expires=" + myDate 
                  + ";domain=.example.com;path=/";
</script>

I tried this:

class dotdict(dict):
    def __getattr__(self, name):
        return self[name]

you can try __getattribute__ too.

make every dict a type of dotdict would be good enough, if you want to init this from a multi-layer dict, try implement __init__ too.

Since id is an attribute don't create an id element, just do this:

myPara.setAttribute("id", "id_you_like");

Using java 8 removeIf

public int getSimilarItems(){
    List<String> one = Arrays.asList("milan", "dingo", "elpha", "hafil", "meat", "iga", "neeta.peeta");
    List<String> two = new ArrayList<>(Arrays.asList("hafil", "iga", "binga", "mike", "dingo")); //Cannot remove directly from array backed collection
    int initial = two.size();

    two.removeIf(one::contains);
    return initial - two.size();
}

The following might work well enough:

Call window as a function.

driver.manage().window().maximize();

Actually these two terms are often used to represent same thing, but there are some exceptional situations. A field can store the state of an object. Also all fields are variables. So it is clear that there can be variables which are not fields. So looking into the 4 type of variables (class variable, instance variable, local variable and parameter variable) we can see that class variables and instance variables can affect the state of an object. In other words if a class or instance variable changes,the state of object changes. So we can say that class variables and instance variables are fields while local variables and parameter variables are not.

If you want to understand more deeply, you can head over to the source below:-

file = open('ValidEmails.txt','wb')
file.write(email.encode('utf-8', 'ignore'))

This is solve your encode error also.

There is not much point in declaring an array without size. An array is about size. When you declare an array of specific size, you specify the fixed number of slots available in a collection that can hold things, and accordingly memory is allocated. To add something to it, you will need to anyway reinitialize the existing array (even if you're resizing the array, see this thread). One of the rare cases where you would want to initialise an empty array would be to pass array as an argument.

If you want to define a collection when you do not know what size it could be of possibly, array is not your choice, but something like a List<T> or similar.

That said, the only way to declare an array without specifying size is to have an empty array of size 0. hemant and Alex Dn provides two ways. Another simpler alternative is to just:

string[] a = { };

[The elements inside the bracket should be implicitly convertible to type defined, for instance, string[] a = { "a", "b" };]

Or yet another:

var a = Enumerable.Empty<string>().ToArray();

Here is a more declarative way:

public static class Array<T>
{
    public static T[] Empty()
    {
        return Empty(0);
    }

    public static T[] Empty(int size)
    {
        return new T[size];
    }
}

Now you can call:

var a = Array<string>.Empty();

//or

var a = Array<string>.Empty(5);

httpOnly is supported as of Tomcat 6.0.19 and Tomcat 5.5.28.

See the changelog entry for bug 44382.

The last comment for bug 44382 states, "this has been applied to 5.5.x and will be included in 5.5.28 onwards." However, it does not appear that 5.5.28 has been released.

The httpOnly functionality can be enabled for all webapps in conf/context.xml:

<Context useHttpOnly="true">
...
</Context>

My interpretation is that it also works for an individual context by setting it on the desired Context entry in conf/server.xml (in the same manner as above).

You can't do it directly, because you don't have write access to the underlying buffer (until C++11; see Dietrich Epp's comment). You'll have to do it first in a c-string, then copy it into a std::string:

  char buff[100];
  snprintf(buff, sizeof(buff), "%s", "Hello");
  std::string buffAsStdStr = buff;

But I'm not sure why you wouldn't just use a string stream? I'm assuming you have specific reasons to not just do this:

  std::ostringstream stringStream;
  stringStream << "Hello";
  std::string copyOfStr = stringStream.str();

Using the DateTime class available in PHP version 5.2 it would be done like this:

$datetime = new DateTime('17 Oct 2008');
echo $datetime->format('c');

See it in action

As of PHP 5.4 you can do this as a one-liner:

echo (new DateTime('17 Oct 2008'))->format('c');

    for (int i = 0; i < n; i++) {
        int change = i + random.nextInt(n - i);
        swap(a, i, change);
    }
}

}

The standard requires the array length to be a value that is computable at compile time so that the compiler is able to allocate enough space on the stack. In your case, you are trying to set the array length to a value that is unknown at compile time. Yes, i know that it seems obvious that it should be known to the compiler, but this is not the case here. The compiler cannot make any assumptions about the contents of non-constant variables. So go with:

const int row = 8;
const int col= 8;
int a[row][col];

UPD: some compilers will actually allow you to pull this off. IIRC, g++ has this feature. However, never use it because your code will become un-portable across compilers.

If you want to create a new branch remotely in the origin, you need to create the same branch locally first:

$ git clone -b new-branch
$ git push origin new-branch

If you have setup.py in your project and you use find_packages() within it, it is necessary to have an __init__.py file in every directory for packages to be automatically found.

Packages are only recognized if they include an __init__.py file

UPD: If you want to use implicit namespace packages without __init__.py you just have to use find_namespace_packages() instead

Be aware that the line-height approach fails if you have a long sentence in the span which breaks the line because there's not enough space. In this case, you would have two lines with a gap with the height of the N pixels specified in the property.

I stuck into it when I wanted to show an image with vertically centered text on its right side which works in a responsive web application. As a base I use the approach suggested by Eric Nickus and Felipe Tadeo.

If you want to achieve:

and this:

.container {_x000D_
    background: url( "https://i.imgur.com/tAlPtC4.jpg" ) no-repeat;_x000D_
    display: inline-block;_x000D_
    background-size: 40px 40px; /* image's size */_x000D_
    height: 40px; /* image's height */_x000D_
    padding-left: 50px; /* image's width plus 10 px (margin between text and image) */_x000D_
}_x000D_
_x000D_
.container span {_x000D_
    height: 40px; /* image's height */_x000D_
    display: table-cell;_x000D_
    vertical-align: middle;_x000D_
}

<span class="container">_x000D_
    <span>This is a centered sentence next to an image</span>_x000D_
</span>

There's an open-source multi-platform client, written in Go: drive. It's quite nice and full-featured, and also is in active development.

$ drive help pull
Name
        pull - pulls remote changes from Google Drive
Description
        Downloads content from the remote drive or modifies
         local content to match that on your Google Drive

Note: You can skip checksum verification by passing in flag `-ignore-checksum`

* For usage flags: `drive pull -h`

You can try:

#!/bin/bash
d=$(date +%Y-%m-%d)
echo "$d"

EDIT: Changed y to Y for 4 digit date as per QuantumFool's comment.

Use BigDecimal, not double

The Answer by adatapost is right about using String::split but wrong about using double to represent your longitude-latitude values. The float/Float and double/Double types use floating-point technology which trades away accuracy for speed of execution.

Instead use BigDecimal to correctly represent your lat-long values.

Use Apache Commons CSV library

Also, best to let a library such as Apache Commons CSV perform the chore of reading and writing CSV or Tab-delimited files.

Example app

Here is a complete example app using that Commons CSV library. This app writes then reads a data file. It uses String::split for the writing. And the app uses BigDecimal objects to represent your lat-long values.

package work.basil.example;

import org.apache.commons.csv.CSVFormat;
import org.apache.commons.csv.CSVPrinter;
import org.apache.commons.csv.CSVRecord;

import java.io.BufferedReader;
import java.io.IOException;

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

            {
                String[] fields = input.split( "," );
                printer.printRecord( fields[ 0 ] , fields[ 1 ] );
            }
        } catch ( IOException e )
        {
            e.printStackTrace();
        }
    }

    //----------|  Read  |-----------------------------
    public void read ( Path path )
    {
        // TODO: Add a check for valid file existing.

        try
        {
            // Read CSV file.
            BufferedReader reader = Files.newBufferedReader( path );
            Iterable < CSVRecord > records = CSVFormat.RFC4180.withFirstRecordAsHeader().parse( reader );
            for ( CSVRecord record : records )
            {
                BigDecimal latitude = new BigDecimal( record.get( "latitude" ) );
                BigDecimal longitude = new BigDecimal( record.get( "longitude" ) );
                System.out.println( "lat: " + latitude + " | long: " + longitude );
            }
        } catch ( IOException e )
        {

    public static void main ( String[] args )
    {
        LatLong app = new LatLong();

        // Write
        Path pathOutput = Paths.get( "/Users/basilbourque/lat-long.csv" );
        app.write( pathOutput );
        System.out.println( "Writing file: " + pathOutput );

        // Read
        Path pathInput = Paths.get( "/Users/basilbourque/lat-long.csv" );

As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping as a meta-annotation. So:

Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:

@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)

Yes, there is such a way. You can create a meta annotation like following:

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
    @AliasFor(annotation = RequestMapping.class, attribute = "value")
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "method")
    RequestMethod[] method() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "params")
    String[] params() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "headers")
    String[] headers() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "consumes")
    String[] consumes() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "produces")
    String[] produces() default {};
}

Then you can use the default settings or even override them as you want:

@JsonRequestMapping(method = POST)
public String defaultSettings() {
    return "Default settings";
}

@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
    return json;
}

You can read more about AliasFor in spring's javadoc and github wiki.

I had this issue when I installed under Program Files, which they do not recommend due to write issues. This might only be a problem if you are not logged in as an admin and use a password to install. I just uninstalled and installed in a directory that did not need admin privileges.

Type doesn't work on certain classes. If you're not sure of the object's type use the __class__ method, as so:

>>>obj = 'a string'
>>>obj.__class__ == str
True

Also see this article - http://www.siafoo.net/article/56

Use READ_UNCOMMITTED in situation where source is highly unlikely to change.

• When reading historical data. e.g some deployment logs that happened two days ago.
• When reading metadata again. e.g. metadata based application.

Don't use READ_UNCOMMITTED when you know souce may change during fetch operation.

You might need a ~/.ssh/config:

Host gitlab.YOURDOMAIN.DOMAIN
    Port 1111
    IdentityFile ~/.ssh/id_rsa

and then you can use git clone git@DOMAINandREPOSITORY. This means you always use the user git.

    }   

    double getMean() {
        double sum = 0.0;
        for(double a : data)
            sum += a;
        return sum/size;
    }

    double getVariance() {
        double mean = getMean();
        double temp = 0;
        for(double a :data)
            temp += (a-mean)*(a-mean);
        return temp/(size-1);
    }

    double getStdDev() {
        return Math.sqrt(getVariance());
    }

    public double median() {
       Arrays.sort(data);
       if (data.length % 2 == 0)
          return (data[(data.length / 2) - 1] + data[data.length / 2]) / 2.0;
       return data[data.length / 2];

The cleanest way I found to do this is create a child of 'ThemeOverlay.AppCompat.Dark.ActionBar'. In the example, I set the Toolbar's background color to RED and text's color to BLUE.

<style name="MyToolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">#FF0000</item>
    <item name="android:textColorPrimary">#0000FF</item>
</style>

You can then apply your theme to the toolbar:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    app:theme="@style/MyToolbar"
    android:minHeight="?attr/actionBarSize"/>

Note that the downside of garbage-collecting your repository is that, well, the garbage gets collected. As we all know as computer users, files we consider garbage right now might turn out to be very valuable three days in the future. The fact that git keeps most of its debris around has saved my bacon several times – by browsing all the dangling commits, I have recovered much work that I had accidentally canned.

So don’t be too much of a neat freak in your private clones. There’s little need for it.

OTOH, the value of data recoverability is questionable for repos used mainly as remotes, eg. the place all the devs push to and/or pulled from. There, it might be sensible to kick off a GC run and a repacking frequently.

You can do this by subsetting the data you pass into your merge:

merge(x = DF1, y = DF2[ , c("Client", "LO")], by = "Client", all.x=TRUE)

Or you can simply delete the column after your current merge :)

Another simple PHP example of using cURL:

<?php
    $ch = curl_init();                    // Initiate cURL
    $url = "http://www.somesite.com/curl_example.php"; // Where you want to post data
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST, true);  // Tell cURL you want to post something
    curl_setopt($ch, CURLOPT_POSTFIELDS, "var1=value1&var2=value2&var_n=value_n"); // Define what you want to post
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
    $output = curl_exec ($ch); // Execute

    curl_close ($ch); // Close cURL handle

    var_dump($output); // Show output
?>

Example found here: http://devzone.co.in/post-data-using-curl-in-php-a-simple-example/

Instead of using curl_setopt you can use curl_setopt_array.

form

• directive in module ng Directive that instantiates FormController.

If the name attribute is specified, the form controller is published onto the current scope under this name.

Alias: ngForm

In Angular, forms can be nested. This means that the outer form is valid when all of the child forms are valid as well. However, browsers do not allow nesting of elements, so Angular provides the ngForm directive which behaves identically to but can be nested. This allows you to have nested forms, which is very useful when using Angular validation directives in forms that are dynamically generated using the ngRepeat directive. Since you cannot dynamically generate the name attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an ngForm directive and nest these in an outer form element.

CSS classes

ng-valid is set if the form is valid.

ng-invalid is set if the form is invalid.

ng-pristine is set if the form is pristine.

ng-dirty is set if the form is dirty.

ng-submitted is set if the form was submitted.

Keep in mind that ngAnimate can detect each of these classes when added and removed.

Submitting a form and preventing the default action

Since the role of forms in client-side Angular applications is different than in classical roundtrip apps, it is desirable for the browser not to translate the form submission into a full page reload that sends the data to the server. Instead some javascript logic should be triggered to handle the form submission in an application-specific way.

For this reason, Angular prevents the default action (form submission to the server) unless the element has an action attribute specified.

You can use one of the following two ways to specify what javascript method should be called when a form is submitted:

ngSubmit directive on the form element

ngClick directive on the first button or input field of type submit (input[type=submit])

To prevent double execution of the handler, use only one of the ngSubmit or ngClick directives.

This is because of the following form submission rules in the HTML specification:

If a form has only one input field then hitting enter in this field triggers form submit (ngSubmit) if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter doesn't trigger submit if a form has one or more input fields and one or more buttons or input[type=submit] then hitting enter in any of the input fields will trigger the click handler on the first button or input[type=submit] (ngClick) and a submit handler on the enclosing form (ngSubmit).

Any pending ngModelOptions changes will take place immediately when an enclosing form is submitted. Note that ngClick events will occur before the model is updated.

Use ngSubmit to have access to the updated model.

app.js:

angular.module('formExample', [])
  .controller('FormController', ['$scope', function($scope) {
    $scope.userType = 'guest';
  }]);

Form:

<form name="myForm" ng-controller="FormController" class="my-form">
  userType: <input name="input" ng-model="userType" required>
  <span class="error" ng-show="myForm.input.$error.required">Required!</span>
  userType = {{userType}}
  myForm.input.$valid = {{myForm.input.$valid}}
  myForm.input.$error = {{myForm.input.$error}}
  myForm.$valid = {{myForm.$valid}}
  myForm.$error.required = {{!!myForm.$error.required}}
 </form>

I just used target="_blank" under form tag and it worked fine with FF and Chrome where it opens in a new tag but with IE it opens in a new window.

In RMI, with regards to ports there are two distinct mechanisms involved:

1. By default, the RMI Registry uses port 1099

2. Client and server (stubs, remote objects) communicate over random ports unless a fixed port has been specified when exporting a remote object. The communcation is started via a socket factory which uses 0 as starting port, which means use any port that's available between 1 and 65535.

If you want to really get only "path" without querystring, you can use url library to parse and get only path part of url.

var url = require('url');

//auth required or redirect
app.use('/account', function(req, res, next) {
    var path = url.parse(req.url).pathname;
    if ( !req.session.user ) {
      res.redirect('/login?ref='+path);
    } else {
      next();
    }
});

It looks like, when you try to delete the same object and then again update the same object, then it gives you this error. As after every update hibernate for safe checking fires how many rows were updated, but during the code the data must have been deleted. Over here hibernate distinguish between the objects based on the key what u have assigned or the equals method.

so, just go through once through your code for this check, or try with implementing equals & hashcode method correctly which might help.

There also exists a UNIQUE KEY. The main difference between PRIMARY KEY and UNIQUE KEY is that the PRIMARY KEY never takes NULL value while a UNIQUE KEY may take NULL value. Also, there can be only one PRIMARY KEY in a table while UNIQUE KEY may be more than one.

I think you should re-format your code a bit:

#!/bin/bash
if [ ! -d /home/mlzboy/b2c2/shared/db ]; then
    mkdir -p /home/mlzboy/b2c2/shared/db;
fi;

Window runs IE10 will be auto update to IE11+ and will be standardized W3C

Nowaday, we don't need to support IE8-

    <!DOCTYPE html>
    <!--[if lt IE 9]><html class="ie ie8"><![endif]-->
    <!--[if IE 9]><html class="ie ie9"><![endif]-->
    <!--[if (gt IE 9)|!(IE)]><!--><html><!--<![endif]-->
    <head>
        ...
        <!--[if lt IE 8]><meta http-equiv="Refresh" content="0;url=/error-browser.html"><![endif]--
        ...
    </head>

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

You only need to prefix an if statement with @ if you're not already inside a razor code block.

Edit: You have a couple of things wrong with your code right now.

You're declaring nmb, but never actually doing anything with the value. So you need figure out what that's supposed to actually be doing. In order to fix your code, you need to make a couple of tiny changes:

@if (ViewBag.Articles != null)
{
    int nmb = 0;
    foreach (var item in ViewBag.Articles)
    {
        if (nmb % 3 == 0)
        {
            @:<div class="row"> 
        }

        <a href="@Url.Action("Article", "Programming", new { id = item.id })">
            <div class="tasks">
                <div class="col-md-4">
                    <div class="task important">
                        <h4>@item.Title</h4>
                        <div class="tmeta">
                            <i class="icon-calendar"></i>
                                @item.DateAdded - Pregleda:@item.Click
                            <i class="icon-pushpin"></i> Authorrr
                        </div>
                    </div>
                </div>
            </div>
        </a>
        if (nmb % 3 == 0)
        {
            @:</div>
        }
    }
}

The important part here is the @:. It's a short-hand of <text></text>, which is used to force the razor engine to render text.

One other thing, the HTML standard specifies that a tags can only contain inline elements, and right now, you're putting a div, which is a block-level element, inside an a.

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

If you still need to use the HTTP Module you need to configure it (.NET 4.0 framework) as follows:

<system.webServer>
   <modules runAllManagedModulesForAllRequests="true">
       <add name="MyModule" type="[Namespace].[Class], [assembly]"/>
   </modules>
   <validation validateIntegratedModeConfiguration="false"/>
</system.webServer>

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

Here is another simple answer

gsub("^.*:","", string)

The resource drawable names are not stored as strings, so you'll have to resolve the string into the integer constant generated during the build. You can use the Resources class to resolve the string into that integer.

Resources res = getResources();
int resourceId = res.getIdentifier(
   generatedString, "drawable", getPackageName() );
imageView.setImageResource( resourceId );

This resolves your generated string into the integer that the ImageView can use to load the right image.

Alternately, you can use the id to load the Drawable manually and then set the image using that drawable instead of the resource ID.

Drawable drawable = res.getDrawable( resourceId );
imageView.setImageDrawable( drawable );

Within an event handler function or object method, one way to access the properties of "the containing element" is to use the special this keyword. The this keyword represents the owner of the function or method currently being processed. So:

• For a global function, this represents the window.

• For an object method, this represents the object instance.

• And in an event handler, this represents the element that received the event.

For example:

<!DOCTYPE html>
<html>
    <head>
        <script>
        function mouseDown() {
            alert(this);
        }
        </script>
    </head>
    <body>
        <p onmouseup="mouseDown();alert(this);">Hi</p>
    </body>
</html>

The content of alert windows after rendering this html respectively are:

object Window
object HTMLParagraphElement

An Event object is associated with all events. It has properties that provide information "about the event", such as the location of a mouse click in the web page.

For example:

<!DOCTYPE html>
<html>
    <head>
        <script>
        function mouseDown(event) {
            var theEvent = event ? event : window.event;
            var locString = "X = " + theEvent.screenX + " Y = " + theEvent.screenY;
            alert(event);
                    alert(locString);
        }
        </script>
    </head>
    <body>
        <p onmouseup="mouseDown(event);">Hi</p>
    </body>
</html>

The content of alert windows after rendering this html respectively are:

object MouseEvent
X = 982 Y = 329

If you want to display date time on view without model, just write this:

Date : @DateTime.Now

The output will be:

Date : 16-Aug-17 2:32:10 PM

click windows-> preferences->Maven. uncheck "Offline" check box. This was not able to download archetype which I was using. When I uncheck it, Everything worked smooth.

If you have no control over the page and wish to watch for some kind of change then the modern method is to use MutationObserver

An example of its use, watching for the src attribute to change of an iframe

new MutationObserver(function(mutations) {_x000D_
  mutations.some(function(mutation) {_x000D_
    if (mutation.type === 'attributes' && mutation.attributeName === 'src') {_x000D_
      console.log(mutation);_x000D_
      console.log('Old src: ', mutation.oldValue);_x000D_
      console.log('New src: ', mutation.target.src);_x000D_
      return true;_x000D_
    }_x000D_
_x000D_
    return false;_x000D_
  });_x000D_
}).observe(document.body, {_x000D_
  attributes: true,_x000D_
  attributeFilter: ['src'],_x000D_
  attributeOldValue: true,_x000D_
  characterData: false,_x000D_
  characterDataOldValue: false,_x000D_
  childList: false,_x000D_
  subtree: true_x000D_
});_x000D_
_x000D_
setTimeout(function() {_x000D_
  document.getElementsByTagName('iframe')[0].src = 'http://jsfiddle.net/';_x000D_
}, 3000);

<iframe src="http://www.google.com"></iframe>

Output after 3 seconds

MutationRecord {oldValue: "http://www.google.com", attributeNamespace: null, attributeName: "src", nextSibling: null, previousSibling: null…}
Old src:  http://www.google.com
New src:  http://jsfiddle.net/

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

Update: The site below is no longer running because, as they say on the site:

As of January 1, 2016, no publicly trusted CA is allowed to issue a SHA-1 certificate. In addition, SHA-1 support was removed by most modern browsers and operating systems in early 2017. Any new certificate you get should automatically use a SHA-2 algorithm for its signature.

Legacy clients will continue to accept SHA-1 certificates, and it is possible to have requested a certificate on December 31, 2015 that is valid for 39 months. So, it is possible to see SHA-1 certificates in the wild that expire in early 2019.

Original answer:

You can also use https://shaaaaaaaaaaaaa.com/ - set up to make this particular task easy. The site has a text box - you type in your site domain name, click the Go button and it then tells you whether the site is using SHA1 or SHA2.

Background

Granted, the answer I linked in the comments is not very helpful. You can specify your own string converter like so.

In [25]: pd.set_option('display.float_format', lambda x: '%.3f' % x)

In [28]: Series(np.random.randn(3))*1000000000
Out[28]: 
0    -757322420.605
1   -1436160588.997
2   -1235116117.064
dtype: float64

I'm not sure if that's the preferred way to do this, but it works.

Converting numbers to strings purely for aesthetic purposes seems like a bad idea, but if you have a good reason, this is one way:

In [6]: Series(np.random.randn(3)).apply(lambda x: '%.3f' % x)
Out[6]: 
0     0.026
1    -0.482
2    -0.694
dtype: object

I do the following using dynamic and LINQ:

    var sql = @"select top 1 person_id, first_name, last_name from Person";
    using (var conn = ConnectionFactory.GetConnection())
    {
        List<Person> person = conn.Query<dynamic>(sql)
                                  .Select(item => new Person()
                                  {
                                      PersonId = item.person_id,
                                      FirstName = item.first_name,
                                      LastName = item.last_name
                                  }
                                  .ToList();

        return person;
    }

Your question title mentions Blocking Queues. However, ConcurrentLinkedQueue is not a blocking queue.

The BlockingQueues are ArrayBlockingQueue, DelayQueue, LinkedBlockingDeque, LinkedBlockingQueue, PriorityBlockingQueue, and SynchronousQueue.

Some of these are clearly not fit for your purpose (DelayQueue, PriorityBlockingQueue, and SynchronousQueue). LinkedBlockingQueue and LinkedBlockingDeque are identical, except that the latter is a double-ended Queue (it implements the Deque interface).

Since ArrayBlockingQueue is only useful if you want to limit the number of elements, I'd stick to LinkedBlockingQueue.

Here is my suggested validation:

var isValid = false;

// Check whether this entered value is numeric.
function checkNumeric() {
    var numericVal = document.getElementById("txt_numeric").value;

    if(isNaN(numericVal) || numericVal == "" || numericVal == null || numericVal.indexOf(' ') >= 0) {
        alert("Please, enter a numeric value!");
        isValid = false;
    } else {
        isValid = true;
    }
}

You could try the "Microsoft Date and Time Picker Control". To use it, in the Toolbox, you right-click and choose "Additional Controls...". Then you check "Microsoft Date and Time Picker Control 6.0" and OK. You will have a new control in the Toolbox to do what you need.

I just found some printscreen of this on : http://www.logicwurks.com/CodeExamplePages/EDatePickerControl.html Forget the procedures, just check the printscreens.

Table cells don't respect margin, but you could use transparent borders instead:

div {
  display: table-cell;
  border: 5px solid transparent;
}

Note: you can't use percentages here... :(

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.

Instead of using $ ssh-agent -s, I used $ eval `ssh-agent -s` to solve this issue.

Here is what I performed step by step (step 2 onwards on GitBash):

1. Cleaned up my .ssh folder at C:\user\<username>\.ssh\
2. Generated a new SSH key
   $ ssh-keygen -t rsa -b 4096 -C "[email protected]"
3. Check if any process id(ssh agent) is already running.
   $ ps aux | grep ssh
4. (Optional) If found any in step 3, kill those
   $ kill <pids>
5. Started the ssh agent
   $ eval `ssh-agent -s`
6. Added ssh key generated in step 2 to ssh agent
   $ ssh-add ~/.ssh/id_rsa

Note that if you want to comment out a single line of printing erb you should do like this

<%#= ["Buck", "Papandreou"].join(" you ") %>

If your data structure has many-to-one mapping between keys and values you should iterate over entries and pick all suitable keys:

public static <T, E> Set<T> getKeysByValue(Map<T, E> map, E value) {
    Set<T> keys = new HashSet<T>();
    for (Entry<T, E> entry : map.entrySet()) {
        if (Objects.equals(value, entry.getValue())) {
            keys.add(entry.getKey());
        }
    }
    return keys;
}

In case of one-to-one relationship, you can return the first matched key:

public static <T, E> T getKeyByValue(Map<T, E> map, E value) {
    for (Entry<T, E> entry : map.entrySet()) {
        if (Objects.equals(value, entry.getValue())) {
            return entry.getKey();
        }
    }
    return null;
}

In Java 8:

public static <T, E> Set<T> getKeysByValue(Map<T, E> map, E value) {
    return map.entrySet()
              .stream()
              .filter(entry -> Objects.equals(entry.getValue(), value))
              .map(Map.Entry::getKey)
              .collect(Collectors.toSet());
}

Also, for Guava users, BiMap may be useful. For example:

BiMap<Token, Character> tokenToChar = 
    ImmutableBiMap.of(Token.LEFT_BRACKET, '[', Token.LEFT_PARENTHESIS, '(');
Token token = tokenToChar.inverse().get('(');
Character c = tokenToChar.get(token);

You can use obj.constructor.name to check the "class" of an object https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/name#Function_names_in_classes

For Example

var error = new Error("ValidationError");
console.log(error.constructor.name);

The above line will log "Error" which is the class name of the object. This could be used with any classes in javascript, if the class is not using a property that goes by the name "name"

You have use the SqlQuery function and indicate the entity to mapping the result.

I send an example as to perform this:

var oficio= new SqlParameter
{
    ParameterName = "pOficio",
    Value = "0001"
};

using (var dc = new PCMContext())
{
    return dc.Database
             .SqlQuery<ProyectoReporte>("exec SP_GET_REPORTE @pOficio",
                                        oficio)
             .ToList();
}

For me none of the above solutions worked (reinstalling, clearing cache, folders etc.).

My problem was solved with:

npm config set registry https://registry.npmjs.org/

def name(**variables):
    return [x for x in variables]

It's used like this:

name(variable=variable)

In C, NAN is declared in <math.h>.

In C++, std::numeric_limits<double>::quiet_NaN() is declared in <limits>.

But for checking whether a value is NaN, you can't compare it with another NaN value. Instead use isnan() from <math.h> in C, or std::isnan() from <cmath> in C++.

STATICFILES_DIRS: You can keep the static files for your project here e.g. the ones used by your templates.

STATIC_ROOT: leave this empty, when you do manage.py collectstatic, it will search for all the static files on your system and move them here. Your static file server is supposed to be mapped to this folder wherever it is located. Check it after running collectstatic and you'll find the directory structure django has built.

--------Edit----------------

As pointed out by @DarkCygnus, STATIC_ROOT should point at a directory on your filesystem, the folder should be empty since it will be populated by Django.

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

or

STATIC_ROOT = '/opt/web/project/static_files'

--------End Edit -----------------

STATIC_URL: '/static/' is usually fine, it's just a prefix for static files.

Eclipse uses it's own internal compiler that can compile to several Java versions.

From Eclipse Help > Java development user guide > Concepts > Java Builder

The Java builder builds Java programs using its own compiler (the Eclipse Compiler for Java) that implements the Java Language Specification.

For Eclipse Mars.1 Release (4.5.1), this can target 1.3 to 1.8 inclusive.

When you configure a project:

[project-name] > Properties > Java Compiler > Compiler compliance level

This configures the Eclipse Java compiler to compile code to the specified Java version, typically 1.8 today.

Host environment variables, eg JAVA_HOME etc, are not used.

The Oracle/Sun JDK compiler is not used.

I would convert csvreader to list, then pop the first element

import csv        

with open(fileName, 'r') as csvfile:
        csvreader = csv.reader(csvfile)
        data = list(csvreader)               # Convert to list
        data.pop(0)                          # Removes the first row

        for row in data:
            print(row)

I went through the exercise to capture low level packet exchange, and found that network connection is only triggered by operations like getInputStream, getOutputStream, getResponseCode, getResponseMessage etc.

Here is the packet exchange captured when I try to write a small program to upload file to Dropbox.

Below is my toy program and annotation

    /* Create a connection LOCAL object,
     * the openConnection() function DOES NOT initiate
     * any packet exchange with the remote server.
     * 
     * The configurations only setup the LOCAL
     * connection object properties.
     */
    HttpURLConnection connection = (HttpURLConnection) dst.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    ...//headers setup
    byte[] testContent = {0x32, 0x32};

    /**
     * This triggers packet exchange with the remote
     * server to create a link. But writing/flushing
     * to a output stream does not send out any data.
     * 
     * Payload are buffered locally.
     */
    try (BufferedOutputStream outputStream = new BufferedOutputStream(connection.getOutputStream())) {
        outputStream.write(testContent);
        outputStream.flush();
    }

    /**
     * Trigger payload sending to the server.
     * Client get ALL responses (including response code,
     * message, and content payload) 
     */
    int responseCode = connection.getResponseCode();
    System.out.println(responseCode);

    /* Here no further exchange happens with remote server, since
     * the input stream content has already been buffered
     * in previous step
     */
    try (InputStream is = connection.getInputStream()) {
        Scanner scanner = new Scanner(is);
        StringBuilder stringBuilder = new StringBuilder();
        while (scanner.hasNextLine()) {
        stringBuilder.append(scanner.nextLine()).append(System.lineSeparator());
        }
    }

    /**
     * Trigger the disconnection from the server.
     */
    String responsemsg = connection.getResponseMessage();
    System.out.println(responsemsg);
    connection.disconnect();

Either use the generated short name (C:\Progra~1) or surround the path with quotation marks.

You can use the curses.h library in linux as mentioned in the other answer.

You can install it in Ubuntu by:

sudo apt-get update

sudo apt-get install ncurses-dev

I took the installation part from here.

For debian after installing node enter

curl -k -O -L https://npmjs.org/install.sh    
ln -s /usr/bin/nodejs /usr/bin/node  
sh install.sh

In:

for i in range(c/10):

You're creating a float as a result - to fix this use the int division operator:

for i in range(c // 10):

As said, JsonMappingException: out of START_ARRAY token exception is thrown by Jackson object mapper as it's expecting an Object {} whereas it found an Array [{}] in response.

A simpler solution could be replacing the method getLocations with:

public static List<Location> getLocations(InputStream inputStream) {
    ObjectMapper objectMapper = new ObjectMapper();
    try {
        TypeReference<List<Location>> typeReference = new TypeReference<>() {};
        return objectMapper.readValue(inputStream, typeReference);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

On the other hand, if you don't have a pojo like Location, you could use:

TypeReference<List<Map<String, Object>>> typeReference = new TypeReference<>() {};
return objectMapper.readValue(inputStream, typeReference);

Had similar problem due to some CSV files that had various names for the same column.
This was the solution:

I wrote a function to return the first valid column name in a list, then used that...

# Return the string name of the first name in names that is a column name in tbl
# else null
ChooseCorrectColumnName <- function(tbl, names) {
for(n in names) {
    if (n %in% colnames(tbl)) {
        return(n)
    }
}
return(null)
}

then...

cptcodefieldname = ChooseCorrectColumnName(file, c("CPT", "CPT.Code"))
icdcodefieldname = ChooseCorrectColumnName(file, c("ICD.10.CM.Code", "ICD10.Code"))

if (is.null(cptcodefieldname) || is.null(icdcodefieldname)) {
        print("Bad file column name")

file[cptcodefieldname] = as.character(file[cptcodefieldname])
file[icdcodefieldname] = as.character(file[icdcodefieldname])
for (i in 1:length(file[cptcodefieldname])) {
    cpt_valid_icds[file[cptcodefieldname][i]] <<- unique(c(cpt_valid_icds[[file[cptcodefieldname][i]]], file[icdcodefieldname][i]))
}

Had a similar problem that resolved by adding both these two parameters to ForeignKey: null=True, on_delete=models.SET_NULL

This code copies all stored procedures in the Master database to the target database, you can copy just the procedures you like by filtering the query on procedure name.

@sql is defined as nvarchar(max), @Name is the target database

DECLARE c CURSOR FOR 
   SELECT Definition
   FROM [ResiDazeMaster].[sys].[procedures] p
   INNER JOIN [ResiDazeMaster].sys.sql_modules m ON p.object_id = m.object_id

OPEN c

FETCH NEXT FROM c INTO @sql

WHILE @@FETCH_STATUS = 0 
BEGIN
   SET @sql = REPLACE(@sql,'''','''''')
   SET @sql = 'USE [' + @Name + ']; EXEC(''' + @sql + ''')'

   EXEC(@sql)

   FETCH NEXT FROM c INTO @sql
END             

CLOSE c
DEALLOCATE c

wll it looks like I found the answer, although I havent tested it yet

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

You can use Tommy's method in forms as well:

@using (Html.BeginForm("Action", "Controller", FormMethod.Get, new { target = "_blank" }))
{
//code
}

METHOD 1 ( Recommanded )

Library YouTubeExtractor

Add into your gradle file

 allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }

And dependencies

 compile 'com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'

Add this small code and you done. Demo HERE

public class MainActivity extends AppCompatActivity {

    private static final String YOUTUBE_ID = "ea4-5mrpGfE";

    private final YouTubeExtractor mExtractor = YouTubeExtractor.create();


    private Callback<YouTubeExtractionResult> mExtractionCallback = new Callback<YouTubeExtractionResult>() {
        @Override
        public void onResponse(Call<YouTubeExtractionResult> call, Response<YouTubeExtractionResult> response) {
            bindVideoResult(response.body());
        }

        @Override
        public void onFailure(Call<YouTubeExtractionResult> call, Throwable t) {
            onError(t);
        }
    };


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


//        For android youtube extractor library  com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'
        mExtractor.extract(YOUTUBE_ID).enqueue(mExtractionCallback);

    }


    private void onError(Throwable t) {
        t.printStackTrace();
        Toast.makeText(MainActivity.this, "It failed to extract. So sad", Toast.LENGTH_SHORT).show();
    }


    private void bindVideoResult(YouTubeExtractionResult result) {

//        Here you can get download url link
        Log.d("OnSuccess", "Got a result with the best url: " + result.getBestAvailableQualityVideoUri());

        Toast.makeText(this, "result : " + result.getSd360VideoUri(), Toast.LENGTH_SHORT).show();
    }
}

You can get download link in bindVideoResult() method.

METHOD 2

Using this library android-youtubeExtractor

Add into gradle file

repositories {
    maven { url "https://jitpack.io" }
}

compile 'com.github.HaarigerHarald:android-youtubeExtractor:master-SNAPSHOT'

Here is the code for getting download url.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url
                String downloadUrl = ytFiles.get(itag).getUrl();
            }
        }
    };

    ytEx.execute(youtubeLink);

Have you created a package.json file? Maybe run this command first again.

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm init

It creates a package.json file in your folder.

Then run,

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm install socket.io --save

The --save ensures your module is saved as a dependency in your package.json file.

Let me know if this works.

Using dynamic programming, the time complexity is T(n*m) and space complexity T(m):

def binomial(n, k):
""" (int, int) -> int

         | c(n-1, k-1) + c(n-1, k), if 0 < k < n
c(n,k) = | 1                      , if n = k
         | 1                      , if k = 0

Precondition: n > k

>>> binomial(9, 2)
36
"""

c = [0] * (n + 1)
c[0] = 1
for i in range(1, n + 1):
    c[i] = 1
    j = i - 1
    while j > 0:
        c[j] += c[j - 1]
        j -= 1

return c[k]

Elements in HashSet can't be sorted. Whenever you put elements into HashSet, it can mess up the ordering of the whole set. It is deliberately designed like that for performance. When you don't care about the order, HashSet will be the most efficient set for fast insertion and search.

TreeSet will sort all the elements automatically every time you insert an element.

Perhaps, what you are trying to do is to sort just once. In that case, TreeSet is not the best option because it needs to determine the placing of newly added elements all the time.

The most efficient solution is to use ArrayList. Create a new list and add all the elements then sort it once. If you want to retain only unique elements (remove all duplicates like set does, then put the list into a LinkedHashSet, it will retain the order you have already sorted)

List<Integer> list = new ArrayList<>();
list.add(6);
list.add(4);
list.add(4);
list.add(5);
Collections.sort(list);
Set<Integer> unique = new LinkedHashSet<>(list); // 4 5 6
// The above line is not copying the objects! It only copies references.

Now, you've gotten a sorted set if you want it in a list form then convert it into list.

This answer will be robust enough to work for elements that aren't on the page, therefore failing gracefully (not throwing an exception) if the selector failed to find the element.

const nameSelector = '[data-automation="name-input"]';
const nameInputIsDisplayed = () => {
    return $$(nameSelector).count()
        .then(count => count !== 0)
}
it('should be displayed', () => {
    nameInputIsDisplayed().then(isDisplayed => {
        expect(isDisplayed).toBeTruthy()
    })
})

You can compare different methods very well explained on this page: http://blog.themeforest.net/tutorials/vertical-centering-with-css/

The method they recommend is adding a empty floating element before the content you cant centered, and clearing it. It doesn't have the downside you mentioned.

I forked your JSBin to apply it : http://jsbin.com/iquviq/7/edit

HTML

<div id="floater">
</div>

<div id="content">
  Content here
</div>

CSS

#floater {
  float: left; 
  height: 50%; 
  margin-bottom: -300px;
}

#content {
  clear: both; 
  width: 200px;
  height: 600px;
  position: relative; 
  margin: auto;
}

A bit late to the party, but JQuery change inner text but preserve html has at least one approach not mentioned here:

var $td = $("#demoTable td");
$td.html($td.html().replace('Tap on APN and Enter', 'new text'));

Without fixing the text, you could use (snother)[https://stackoverflow.com/a/37828788/1587329]:

var $a = $('#demoTable td');
var inner = '';
$a.children.html().each(function() {
    inner = inner + this.outerHTML;
});
$a.html('New text' + inner);

SELECT 
  CAST(
    CASE WHEN Obsolete = 'N' 
    or InStock = 'Y' THEN ELSE 0 END AS bit
  ) as Saleable, *

It looks like in one of last c++ boost version appeared library to provide exactly what You want, probably the code would be multiplatform. It is boost::stacktrace, which You can use like as in boost sample:

#include <filesystem>
#include <sstream>
#include <fstream>
#include <signal.h>     // ::signal, ::raise
#include <boost/stacktrace.hpp>

const char* backtraceFileName = "./backtraceFile.dump";

void signalHandler(int)
{
    ::signal(SIGSEGV, SIG_DFL);
    ::signal(SIGABRT, SIG_DFL);
    boost::stacktrace::safe_dump_to(backtraceFileName);
    ::raise(SIGABRT);
}

void sendReport()
{
    if (std::filesystem::exists(backtraceFileName))
    {
        std::ifstream file(backtraceFileName);

        auto st = boost::stacktrace::stacktrace::from_dump(file);
        std::ostringstream backtraceStream;
        backtraceStream << st << std::endl;

        // sending the code from st

        file.close();
        std::filesystem::remove(backtraceFileName);
    }
}

int main()
{
    ::signal(SIGSEGV, signalHandler);
    ::signal(SIGABRT, signalHandler);

    sendReport();
    // ... rest of code
}

In Linux You compile the code above:

g++ --std=c++17 file.cpp -lstdc++fs -lboost_stacktrace_backtrace -ldl -lbacktrace

Example backtrace copied from boost documentation:

0# bar(int) at /path/to/source/file.cpp:70
1# bar(int) at /path/to/source/file.cpp:70
2# bar(int) at /path/to/source/file.cpp:70
3# bar(int) at /path/to/source/file.cpp:70
4# main at /path/to/main.cpp:93
5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
6# _start

DataTable, DbDataReader, or IEnumerable<SqlDataRecord> objects can be used to populate a table-valued parameter per the MSDN article Table-Valued Parameters in SQL Server 2008 (ADO.NET).

The following example illustrates using either a DataTable or an IEnumerable<SqlDataRecord>:

SQL Code:

CREATE TABLE dbo.PageView
(
    PageViewID BIGINT NOT NULL CONSTRAINT pkPageView PRIMARY KEY CLUSTERED,
    PageViewCount BIGINT NOT NULL
);
CREATE TYPE dbo.PageViewTableType AS TABLE
(
    PageViewID BIGINT NOT NULL
);
CREATE PROCEDURE dbo.procMergePageView
    @Display dbo.PageViewTableType READONLY
AS
BEGIN
    MERGE INTO dbo.PageView AS T
    USING @Display AS S
    ON T.PageViewID = S.PageViewID
    WHEN MATCHED THEN UPDATE SET T.PageViewCount = T.PageViewCount + 1
    WHEN NOT MATCHED THEN INSERT VALUES(S.PageViewID, 1);
END

C# Code:

private static void ExecuteProcedure(bool useDataTable, 
                                     string connectionString, 
                                     IEnumerable<long> ids) 
{
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    {
        connection.Open();
        using (SqlCommand command = connection.CreateCommand()) 
        {
            command.CommandText = "dbo.procMergePageView";
            command.CommandType = CommandType.StoredProcedure;

            SqlParameter parameter;
            if (useDataTable) {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateDataTable(ids));
            }
            else 
            {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateSqlDataRecords(ids));
            }
            parameter.SqlDbType = SqlDbType.Structured;
            parameter.TypeName = "dbo.PageViewTableType";

            command.ExecuteNonQuery();
        }
    }
}

private static DataTable CreateDataTable(IEnumerable<long> ids) 
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(long));
    foreach (long id in ids) 
    {
        table.Rows.Add(id);
    }
    return table;
}

private static IEnumerable<SqlDataRecord> CreateSqlDataRecords(IEnumerable<long> ids) 
{
    SqlMetaData[] metaData = new SqlMetaData[1];
    metaData[0] = new SqlMetaData("ID", SqlDbType.BigInt);
    SqlDataRecord record = new SqlDataRecord(metaData);
    foreach (long id in ids) 
    {
        record.SetInt64(0, id);
        yield return record;
    }
}

You can try this.

        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }

    rippleClickFunction(){
        //do stuff. 
        // foo==bar
    }

    render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

Yhe only concern is you have to bind the context to the function

    <artifactId>postgresql</artifactId>
    <scope>runtime</scope>
</dependency>

I think the best way is by using TableAdapters rather than using Commands objects, its Update method sends all changes mades (Updates,Inserts and Deletes) inside a Dataset or DataTable straight TO the database. Usually when using a DataGridView you bind to a BindingSource which lets you interact with a DataSource such as Datatables or Datasets.

If you work like this, then on your bounded DataGridView you can just do:

this.customersBindingSource.EndEdit();
this.myTableAdapter.Update(this.myDataSet.Customers);

The 'customersBindingSource' is the DataSource of the DataGridView.

The adapter's Update method will update a single data table and execute the correct command (INSERT, UPDATE, or DELETE) based on the RowState of each data row in the table.

From: https://msdn.microsoft.com/en-us/library/ms171933.aspx

So any changes made inside the DatagridView will be reflected on the Database when using the Update method.

More about TableAdapters: https://msdn.microsoft.com/en-us/library/bz9tthwx.aspx

This way works and with this structure you can create your own framework and do it with less boilerplate.

I tried a couple of codes, but end up using something as simple as (in Python 3):

from datetime import datetime
df['difference_in_datetime'] = abs(df['end_datetime'] - df['start_datetime'])

If your start_datetime and end_datetime columns are in datetime64[ns] format, datetime understands it and return the difference in days + timestamp, which is in timedelta64[ns] format.

If you want to see only the difference in days, you can separate only the date portion of the start_datetime and end_datetime by using (also works for the time portion):

df['start_date'] = df['start_datetime'].dt.date
df['end_date'] = df['end_datetime'].dt.date

And then run:

df['difference_in_days'] = abs(df['end_date'] - df['start_date'])

Very late but I apologize. Sorry if this is "inefficient" but if you found all the above not working, do try this. Works for above 1.10 also

<script>
  $(document).ready(function() {
    var position='expanded';

    $("#topbar").click(function() {
      if (position=='expanded') {
        $(this).animate({height:'200px'});
        position='collapsed';
      } else {
        $(this).animate({height:'400px'});
        position='expanded';
      }
    });
   });
</script>

You can try the following regular expression:

\r?\n

Code:

String input = "\nab\n\n    \n\ncd\nef\n\n\n\n\n";
String[] lines = input.split("\\r?\\n", -1);
int n = 1;
for(String line : lines) {
    System.out.printf("\tLine %02d \"%s\"%n", n++, line);
}

Output:

Line 01 ""
Line 02 "ab"
Line 03 ""
Line 04 "    "
Line 05 ""
Line 06 "cd"
Line 07 "ef"
Line 08 ""
Line 09 ""
Line 10 ""
Line 11 ""
Line 12 ""

easy enough to use the unname() function:

data.frame <- unname(data.frame)

You can get it using the :selected selector, like this:

$("#my_select").change(function() {
  var id = $(this).children(":selected").attr("id");
});

Symbolic or soft link (files or directories, more flexible and self documenting)

#     Source                             Link
ln -s /home/jake/doc/test/2000/something /home/jake/xxx

Hard link (files only, less flexible and not self documenting)

#   Source                             Link
ln /home/jake/doc/test/2000/something /home/jake/xxx

More information: man ln

/home/jake/xxx is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:

1. cd /home/jake/
2. ln -s /home/jake/doc/test/2000/something xxx

Coming to the party very very late, but from my old memory of DOS batch files, you can keep adding a character to the string each loop then look for a string of that many of that character. for 250 iterations, you either have a very long "cycles" string, or you have one loop inside using one set of variables counting to 10, then another loop outside that uses another set of variable counting to 25.

Here is the basic loop to 30:

@echo off
rem put how many dots you want to loop
set cycles=..............................
set cntr=
:LOOP
set cntr=%cntr%.
echo around we go again
if "%cycles%"=="%cntr%" goto done
goto loop
:DONE
echo around we went

There is a much easier and more compact solution for multilevel prototype lookup, but it requires Proxy support. Usage: SUPER(<instance>).<method>(<args>), for example, assuming two classes A and B extends A with method m: SUPER(new B).m().

function SUPER(instance) {
    return new Proxy(instance, {
        get(target, prop) {
            return Object.getPrototypeOf(Object.getPrototypeOf(target))[prop].bind(target);
        }
    });
}

If your jar file already has an absolute pathname as shown, it is particularly easy:

cd /where/you/want/it; jar xf /path/to/jarfile.jar

That is, you have the shell executed by Python change directory for you and then run the extraction.

If your jar file does not already have an absolute pathname, then you have to convert the relative name to absolute (by prefixing it with the path of the current directory) so that jar can find it after the change of directory.

The only issues left to worry about are things like blanks in the path names.

If you want to split into 3 equally distributed groups, the answer is the same as Ben Bolker's answer above - use ggplot2::cut_number(). For sake of completion here are the 3 methods of converting continuous to categorical (binning).

• cut_number(): Makes n groups with (approximately) equal numbers of observation
• cut_interval(): Makes n groups with equal range
• cut_width(): Makes groups of width

My go-to is cut_number() because this uses evenly spaced quantiles for binning observations. Here's an example with skewed data.

library(tidyverse)

skewed_tbl <- tibble(
    counts = c(1:100, 1:50, 1:20, rep(1:10, 3), 
               rep(1:5, 5), rep(1:2, 10), rep(1, 20))
    ) %>%
    mutate(
        counts_cut_number   = cut_number(counts, n = 4),
        counts_cut_interval = cut_interval(counts, n = 4),
        counts_cut_width    = cut_width(counts, width = 25)
        )
