Install a cross compiler, like mingw64 from your package manager. Then compile in the following way: instead of simply calling gcc call i686-w64-mingw32-gcc for 32-bit Windows or x86_64-w64-mingw32-gcc" for 64-bit Windows. I would also use the --static option, as the target system may not have all the libraries.

If you want to compile other language, like Fortran, replace -gcc with -gfortran in the previous commands.

To Install FreeGLUT

1. Download "freeglut 2.8.1 MSVC Package" from http://www.transmissionzero.co.uk/software/freeglut-devel/

2. Extract the compressed file freeglut-MSVC.zip to a folder freeglut

3. Inside freeglut folder:

On 32bit versions of windows

copy all files in include/GL folder to C:\Program Files\Windows Kits\8.0\Include\um\gl

copy all files in lib folder to C:\Program Files\Windows Kits\8.0\Lib\win8\um\ (note: Lib\freeglut.lib in a folder goes into x86)

copy freeglut.dll to C:\windows\system32

On 64bit versions of windows:(not 100% sure but try)

copy all files in include/GL folder to C:\Program Files(x86)\Windows Kits\8.0\Include\um\gl

copy all files in lib folder to C:\Program Files(x86)\Windows Kits\8.0\Lib\win8\um\ (note: Lib\freeglut.lib in a folder goes into x86)

copy freeglut.dll to C:\windows\SysWOW64

Another neat option is to use the Directive as an element and not as an attribute.

@Directive({
   selector: 'app-directive'
})
export class InformativeDirective implements AfterViewInit {

    @Input()
    public first: string;

    @Input()
    public second: string;

    ngAfterViewInit(): void {
       console.log(`Values: ${this.first}, ${this.second}`);
    }
}

And this directive can be used like that:

<app-someKindOfComponent>
    <app-directive [first]="'first 1'" [second]="'second 1'">A</app-directive>
    <app-directive [first]="'First 2'" [second]="'second 2'">B</app-directive>
    <app-directive [first]="'First 3'" [second]="'second 3'">C</app-directive>
</app-someKindOfComponent>`

Simple, neat and powerful.

This answer is a little variance for the question. Sometimes, we only need the sql only for debug purposes in runtime. In that case, there are a more easy way, using debug on editors.

• Put a breakpoint on org.hibernate.loader.Loader.loadEntityBatch (or navigate on the stack until there);
• When execution is suspended, look the value of variable this.sql ;

This is for hibernate 3. I'm not sure that this work on other versions.

It is possible to make a text-input multi-line by giving it the word-break: break-word; attribute. (Only tested this in Chrome)

For anyone trying the answers to this question to get the stdout from a Python script note that Python buffers its stdout, and therefore it may take a while to see the stdout.

This can be rectified by adding the following after each stdout write in the target script:

sys.stdout.flush()

If the elapsed event takes longer then the interval, it will create another thread to raise the elapsed event. But there is a workaround for this

static void timer_Elapsed(object sender, ElapsedEventArgs e)    
{     
   try
   {
      timer.Stop(); 
      Thread.Sleep(2000);        
      Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);    
   }
   finally
   {
     timer.Start();
   }
}

Try this

 $(function() { 
  $('input[type="checkbox"]').bind('click',function() {
    $('input[type="checkbox"]').not(this).prop("checked", false);
  });
});

function InvalidValueError(value, type) {
    this.message = "Expected `" + type.name + "`: " + value;
    var error = new Error(this.message);
    this.stack = error.stack;
}
InvalidValueError.prototype = new Error();
InvalidValueError.prototype.name = InvalidValueError.name;
InvalidValueError.prototype.constructor = InvalidValueError;

@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...

There are a number of different ways you could do this. To begin with, matplotlib will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you want to control which colors matplotlib cycles through, use ax.set_color_cycle:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you'd like to explicitly specify the colors that will be used, just pass it to the color kwarg (html colors names are accepted, as are rgb tuples and hex strings):

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

Finally, if you'd like to automatically select a specified number of colors from an existing colormap:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]

for i, color in enumerate(colors, start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you don't mind forwarding through a 3rd party server, JSConsole is a rather useful remote debugger for JavaScript.

You should read this getopts tutorial.

Example with -a switch that requires an argument :

#!/bin/bash

while getopts ":a:" opt; do
  case $opt in
    a)
      echo "-a was triggered, Parameter: $OPTARG" >&2
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :)
      echo "Option -$OPTARG requires an argument." >&2
      exit 1
      ;;
  esac
done

Like greybot said(getopt != getopts) :

The external command getopt(1) is never safe to use, unless you know it is GNU getopt, you call it in a GNU-specific way, and you ensure that GETOPT_COMPATIBLE is not in the environment. Use getopts (shell builtin) instead, or simply loop over the positional parameters.

I don't think you'll get a better way than your function.

It is clean, easy to follow and understand, and returns the result of the condition (no return (...) ? true : false mess).

You can use regular expressions in Javascript to do pattern matching of strings.

For example:

var s = "hello world!";
if (s.match(/hello.*/)) {
  // do something
}

The match() test is much like WHERE s LIKE 'hello%' in SQL.

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

To install GLIBC_2.14 or GLIBC_2.15, download package from /gnu/libc/ index at

https://ftp.gnu.org/gnu/libc/

Then follow instructions listed by Timo:

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz

2. cd glibc-2.14

3. mkdir build

4. cd build

5. ../configure --prefix=/opt/glibc-2.14

6. make

7. sudo make install

8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

// (pDog.*doSomething)(); // if pDog is a reference

I found a solution on Stack Overflow for Java program run configurations which also works for JUnit run configurations.

You can get the full command executed by your configuration on the Debug tab, or more specifically the Debug view.

1. Run your application
2. Go to your Debug perspective
3. There should be an entry in there (in the Debug View) for the app you've just executed
4. Right-click the node which references java.exe or javaw.exe and select Properties In the dialog that pops up you'll see the Command Line which includes all jars, parameters, etc

You're calling e.nextElement() twice inside your loop when you're only guaranteed that you can call it once without an exception. Rewrite the loop like so:

while(e.hasMoreElements()){
  String param = e.nextElement();
  System.out.println(param);
}

I had this challenge when working on a Rails 6 API application in Ubuntu 20.04.

I had already existing models, and I needed to generate corresponding controllers for the models and also add their allowed attributes in the controller params.

Here's how I did it:

I used the rails generate scaffold_controller to get it done.

I simply ran the following commands:

rails generate scaffold_controller School name:string logo:json motto:text address:text

rails generate scaffold_controller Program name:string logo:json school:references

This generated the corresponding controllers for the models and also added their allowed attributes in the controller params, including the foreign key attributes.

create  app/controllers/schools_controller.rb
invoke  test_unit
create    test/controllers/schools_controller_test.rb

create  app/controllers/programs_controller.rb
invoke  test_unit
create    test/controllers/programs_controller_test.rb

That's all.

I hope this helps

            if(!contains(e))
            return super.add(e);
            else
            return false;
        }
    };
    lst.add("ABC");
    lst.add("ABC");
    lst.add("ABCD");
    lst.add("ABCD");
    lst.add("ABCE");
    System.out.println(lst);

}

This is the better way

Just wanted to add my 2 cents, since I googled this question b/c I found myself in a similar situation...

BE AWARE that while changing from varchar(xxx) to varchar(yyy) is a meta-data change indeed, but changing to varchar(max) is not. Because varchar(max) values (aka BLOB values - image/text etc) are stored differently on the disk, not within a table row, but "out of row". So the server will go nuts on a big table and become unresponsive for minutes (hours).

--no downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(1200)

--huge downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(max)

PS. same applies to nvarchar or course.

Apart of all above answers which I found very interesting, it could sometimes be very easy as it is discussed here :- HOW TO MAKE A MINIMAL REPRODUCIBLE EXAMPLE TO GET HELP WITH R

There are many ways to make a random vector Create a 100 number vector with random values in R rounded to 2 decimals or random matrix in R

mydf1<- matrix(rnorm(20),nrow=20,ncol=5)

Note that sometimes it is very difficult to share a given data because of various reasons such as dimension etc. However, all above answers are great and very important to think and use when one wants to make a reproducible data example. But note that in order to make a data as representative as the original (in case the OP cannot share the original data), it is good to add some information with the data example as (if we call the data mydf1)

class(mydf1)
# this shows the type of the data you have 
dim(mydf1)
# this shows the dimension of your data

Moreover, one should know the type, length and attributes of a data which can be Data structures

#found based on the following 
typeof(mydf1), what it is.
length(mydf1), how many elements it contains.
attributes(mydf1), additional arbitrary metadata.

#If you cannot share your original data, you can str it and give an idea about the structure of your data
head(str(mydf1))

This is what I did:

EF:

using (var context = new SomeDBContext())
{
    foreach (var item in model.ShopItems)  // ShopItems is a posted list with values 
    {    
        var feature = context.Shop
                             .Where(h => h.ShopID == 123 && h.Type == item.Type).ToList();

        feature.ForEach(a => a.SortOrder = item.SortOrder);
    }

    context.SaveChanges();
}

Hope helps someone.

I've tried the other answers listed above, but they are very far from decent solutions when dealing with large files -- especially once a single line's size occupies more than ~1/4 of available RAM.

Both bash and awk slurp the entire line, even though for this problem it's not needed. Bash will error out once a line is too long, even if you have enough memory.

I've implemented an extremely simple, fairly unoptimized python script that when tested with large files (~4 GB per line) doesn't slurp, and is by far a better solution than those given.

If this is time critical code for production, you can rewrite the ideas in C or perform better optimizations on the read call (instead of only reading a single byte at a time), after testing that this is indeed a bottleneck.

Code assumes newline is a linefeed character, which is a good assumption for Unix, but YMMV on Mac OS/Windows. Be sure the file ends with a linefeed to ensure the last line character count isn't overlooked.

from sys import stdin, exit

counter = 0
while True:
    byte = stdin.buffer.read(1)
    counter += 1
    if not byte:
        exit()
    if byte == b'\x0a':
        print(counter-1)
        counter = 0

If in your site you have ajax calls loading some data, and this is the reason the page is loading slow, the best solution I found is with

$(document).ajaxStop(function(){
    alert("All AJAX requests completed");
});

https://jsfiddle.net/44t5a8zm/ - here you can add some ajax calls and test it.

Finding max and min value the easy and manual way. This code is much faster than Math.max.apply; I have tried up to 1000k numbers in array.

function findmax(array)
{
    var max = 0;
    var a = array.length;
    for (counter=0;counter<a;counter++)
    {
        if (array[counter] > max)
        {
            max = array[counter];
        }
    }
    return max;
}

function findmin(array)
{
    var min = array[0];
    var a = array.length;
    for (counter=0;counter<a;counter++)
    {
        if (array[counter] < min)
        {
            min = array[counter];
        }
    }
    return min;
}

I had a problem with the examples above, and the problem was caused by the fact that my select box values are prefilled with fixed length strings of 6 characters, but the parameter being passed in wasn't fixed length.

I have an rpad function which will right pad a string, to the length specified, and with the specified character. So, after padding the parameter it works.

$('#wsWorkCenter').val(rpad(wsWorkCenter, 6, ' '));


function rpad(pStr, pLen, pPadStr) {
if (pPadStr == '') {pPadStr == ' '};
while (pStr.length < pLen)
    pStr = pStr + pPadStr;
return pStr; 
} 

They JKS file is just a container for certificates and key pairs. In a client-side authentication scenario, the various parts of the keys will be located here:

• The client's store will contain the client's private and public key pair. It is called a keystore.
• The server's store will contain the client's public key. It is called a truststore.

The separation of truststore and keystore is not mandatory but recommended. They can be the same physical file.

To set the filesystem locations of the two stores, use the following system properties:

-Djavax.net.ssl.keyStore=clientsidestore.jks

and on the server:

-Djavax.net.ssl.trustStore=serversidestore.jks

To export the client's certificate (public key) to a file, so you can copy it to the server, use

keytool -export -alias MYKEY -file publicclientkey.cer -store clientsidestore.jks

To import the client's public key into the server's keystore, use (as the the poster mentioned, this has already been done by the server admins)

keytool -import -file publicclientkey.cer -store serversidestore.jks

I suggest to use a tick symbol not draw it. Or use webfonts which are free for example: fontello[dot]com You can than replace the tick symbol with a web font glyph.

Lists

ul {padding: 0;}
li {list-style: none}
li:before {
  display:inline-block;
  vertical-align: top;
  line-height: 1em;
  width: 1em;
  height:1em;
  margin-right: 0.3em;
  text-align: center;
  content: '?';
  color: #999;
}

See here: http://jsfiddle.net/hpmW7/3/

Checkboxes

You even have web fonts with tick symbol glyphs and CSS 3 animations. For IE8 you would need to apply a polyfill since it does not understand :checked.

input[type="checkbox"] {
  clip: rect(1px, 1px, 1px, 1px);
  left: -9999px;
  position: absolute !important;
}
label:before,
input[type="checkbox"]:checked + label:before {
  content:'';
  display:inline-block;
  vertical-align: top;
  line-height: 1em;
  border: 1px solid #999;
  border-radius: 0.3em;
  width: 1em;
  height:1em;
  margin-right: 0.3em;
  text-align: center;
}
input[type="checkbox"]:checked + label:before {
  content: '?';
  color: green;
}

There's a Win32 port of the Unix tee command, that does exactly that. See http://unxutils.sourceforge.net/ or http://getgnuwin32.sourceforge.net/

Here is a more complete answer with regard to InnoDB. It is a bit of a lengthy process, but can be worth the effort.

Keep in mind that /var/lib/mysql/ibdata1 is the busiest file in the InnoDB infrastructure. It normally houses six types of information:

• Table Data
• Table Indexes
• MVCC (Multiversioning Concurrency Control) Data
  • Rollback Segments
  • Undo Space
• Table Metadata (Data Dictionary)
• Double Write Buffer (background writing to prevent reliance on OS caching)
• Insert Buffer (managing changes to non-unique secondary indexes)
• See the Pictorial Representation of ibdata1

InnoDB Architecture

Many people create multiple ibdata files hoping for better disk-space management and performance, however that belief is mistaken.

Can I run OPTIMIZE TABLE ?

Unfortunately, running OPTIMIZE TABLE against an InnoDB table stored in the shared table-space file ibdata1 does two things:

• Makes the table’s data and indexes contiguous inside ibdata1
• Makes ibdata1 grow because the contiguous data and index pages are appended to ibdata1

You can however, segregate Table Data and Table Indexes from ibdata1 and manage them independently.

Can I run OPTIMIZE TABLE with innodb_file_per_table ?

Suppose you were to add innodb_file_per_table to /etc/my.cnf (my.ini). Can you then just run OPTIMIZE TABLE on all the InnoDB Tables?

Good News : When you run OPTIMIZE TABLE with innodb_file_per_table enabled, this will produce a .ibd file for that table. For example, if you have table mydb.mytable witha datadir of /var/lib/mysql, it will produce the following:

• /var/lib/mysql/mydb/mytable.frm
• /var/lib/mysql/mydb/mytable.ibd

The .ibd will contain the Data Pages and Index Pages for that table. Great.

Bad News : All you have done is extract the Data Pages and Index Pages of mydb.mytable from living in ibdata. The data dictionary entry for every table, including mydb.mytable, still remains in the data dictionary (See the Pictorial Representation of ibdata1). YOU CANNOT JUST SIMPLY DELETE ibdata1 AT THIS POINT !!! Please note that ibdata1 has not shrunk at all.

InnoDB Infrastructure Cleanup

To shrink ibdata1 once and for all you must do the following:

1. Dump (e.g., with mysqldump) all databases into a .sql text file (SQLData.sql is used below)

2. Drop all databases (except for mysql and information_schema) CAVEAT : As a precaution, please run this script to make absolutely sure you have all user grants in place:

   mkdir /var/lib/mysql_grants
   cp /var/lib/mysql/mysql/* /var/lib/mysql_grants/.
   chown -R mysql:mysql /var/lib/mysql_grants
   

3. Login to mysql and run SET GLOBAL innodb_fast_shutdown = 0; (This will completely flush all remaining transactional changes from ib_logfile0 and ib_logfile1)

4. Shutdown MySQL

5. Add the following lines to /etc/my.cnf (or my.ini on Windows)

   [mysqld]
   innodb_file_per_table
   innodb_flush_method=O_DIRECT
   innodb_log_file_size=1G
   innodb_buffer_pool_size=4G
   

   (Sidenote: Whatever your set for innodb_buffer_pool_size, make sure innodb_log_file_size is 25% of innodb_buffer_pool_size.

   Also: innodb_flush_method=O_DIRECT is not available on Windows)

6. Delete ibdata* and ib_logfile*, Optionally, you can remove all folders in /var/lib/mysql, except /var/lib/mysql/mysql.

7. Start MySQL (This will recreate ibdata1 [10MB by default] and ib_logfile0 and ib_logfile1 at 1G each).

8. Import SQLData.sql

Now, ibdata1 will still grow but only contain table metadata because each InnoDB table will exist outside of ibdata1. ibdata1 will no longer contain InnoDB data and indexes for other tables.

For example, suppose you have an InnoDB table named mydb.mytable. If you look in /var/lib/mysql/mydb, you will see two files representing the table:

• mytable.frm (Storage Engine Header)
• mytable.ibd (Table Data and Indexes)

With the innodb_file_per_table option in /etc/my.cnf, you can run OPTIMIZE TABLE mydb.mytable and the file /var/lib/mysql/mydb/mytable.ibd will actually shrink.

I have done this many times in my career as a MySQL DBA. In fact, the first time I did this, I shrank a 50GB ibdata1 file down to only 500MB!

Give it a try. If you have further questions on this, just ask. Trust me; this will work in the short term as well as over the long haul.

CAVEAT

At Step 6, if mysql cannot restart because of the mysql schema begin dropped, look back at Step 2. You made the physical copy of the mysql schema. You can restore it as follows:

mkdir /var/lib/mysql/mysql
cp /var/lib/mysql_grants/* /var/lib/mysql/mysql
chown -R mysql:mysql /var/lib/mysql/mysql

Go back to Step 6 and continue

UPDATE 2013-06-04 11:13 EDT

With regard to setting innodb_log_file_size to 25% of innodb_buffer_pool_size in Step 5, that's blanket rule is rather old school.

Back on July 03, 2006, Percona had a nice article why to choose a proper innodb_log_file_size. Later, on Nov 21, 2008, Percona followed up with another article on how to calculate the proper size based on peak workload keeping one hour's worth of changes.

I have since written posts in the DBA StackExchange about calculating the log size and where I referenced those two Percona articles.

• Aug 27, 2012 : Proper tuning for 30GB InnoDB table on server with 48GB RAM
• Jan 17, 2013 : MySQL 5.5 - Innodb - innodb_log_file_size higher than 4GB combined?

Personally, I would still go with the 25% rule for an initial setup. Then, as the workload can more accurate be determined over time in production, you could resize the logs during a maintenance cycle in just minutes.

You can make a menu for each fragment, and a global variable that mark which fragment is in use now. and check the value of the variable in onCreateOptionsMenu and inflate the correct menu

 @Override
     public boolean onCreateOptionsMenu(Menu menu) {
         if (fragment_it == 6) {
             MenuInflater inflater = getMenuInflater();
             inflater.inflate(R.menu.custom_actionbar, menu);
         }
     } 

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

If you are using Pypsark, you could also do:

len(df.head(1)) > 0

If you want to never expire a session use 0 or negative value -1.

<session-config>
    <session-timeout>0</session-timeout>
</session-config>

or mention 1440 it indicates 1440 minutes [24hours * 60 minutes]

<session-config>
  <session-timeout>1440</session-timeout><!-- 24hours -->
</session-config>

Session will be expire after 24hours.

ES6 allows a construct where a function argument is specified with a "..." notation such as

function testArgs (...args) {
 // Where you can test picking the first element
 console.log(args[0]); 
}

Using Apache Commons IOUtils you can do this nicely via

List<String> lines = IOUtils.readLines(new StringReader(string));

It's not doing anything clever, but it's nice and compact. It'll handle streams as well, and you can get a LineIterator too if you prefer.

Is there any command in Linux through which i can know if the process is in hang state.

There is no command, but once I had to do a very dumb hack to accomplish something similar. I wrote a Perl script which periodically (every 30 seconds in my case):

• run ps to find list of PIDs of the watched processes (along with exec time, etc)
• loop over the PIDs
• start gdb attaching to the process using its PID, dumping stack trace from it using thread apply all where, detaching from the process
• a process was declared hung if:
  • its stack trace didn't change and time didn't change after 3 checks
  • its stack trace didn't change and time was indicating 100% CPU load after 3 checks
• hung process was killed to give a chance for a monitoring application to restart the hung instance.

But that was very very very very crude hack, done to reach an about-to-be-missed deadline and it was removed a few days later, after a fix for the buggy application was finally installed.

Otherwise, as all other responders absolutely correctly commented, there is no way to find whether the process hung or not: simply because the hang might occur for way to many reasons, often bound to the application logic.

The only way is for application itself being capable of indicating whether it is alive or not. Simplest way might be for example a periodic log message "I'm alive".

You are writing to memory you do not own:

int board[2][50]; //make an array with 3 columns  (wrong)
                  //(actually makes an array with only two 'columns')
...
for (i=0; i<num3+1; i++)
    board[2][i] = 'O';
          ^

Change this line:

int board[2][50]; //array with 2 columns (legal indices [0-1][0-49])
          ^

To:

int board[3][50]; //array with 3 columns (legal indices [0-2][0-49])
          ^

When creating an array, the value used to initialize: [3] indicates array size.
However, when accessing existing array elements, index values are zero based.

For an array created: int board[3][50];
Legal indices are board[0][0]...board[2][49]

EDIT To address bad output comment and initialization comment

add an additional "\n" for formatting output:

Change:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
 }

       ...

To:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
  printf("\n");//at the end of every row, print a new line
}
...  

Initialize board variable:

int board[3][50] = {0};//initialize all elements to zero

The simplest and best way to get yesterday's date is:

subdate(current_date, 1)

Your query would be:

SELECT 
    url as LINK,
    count(*) as timesExisted,
    sum(DateVisited between UNIX_TIMESTAMP(subdate(current_date, 1)) and
        UNIX_TIMESTAMP(current_date)) as timesVisitedYesterday
FROM mytable
GROUP BY 1

For the curious, the reason that sum(condition) gives you the count of rows that satisfy the condition, which would otherwise require a cumbersome and wordy case statement, is that in mysql boolean values are 1 for true and 0 for false, so summing a condition effectively counts how many times it's true. Using this pattern can neaten up your SQL code.

What you want to do is prevent the default action of the click event. To do this, you will need to modify your script like this:

$(document).ready(function() {
  $('.galleryicon').live("click", function(e) {

    $('#mainImage').hide();
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");
    var i = $('<img />').attr('src',this.href).load(function() {
        $('#mainImage').attr('src', i.attr('src'));
        $('#cakebox').css('background-image', 'none');
        $('#mainImage').fadeIn();
    });
    return false; 
    e.preventDefault();
   });
 });

So, you're adding an "e" that represents the event in the line $('.galleryicon').live("click", function(e) { and you're adding the line e.preventDefault();

To check on elasticsearch cluster health you need to use

curl localhost:9200/_cat/health

More on the cat APIs here.

I usually use elasticsearch-head plugin to visualize that.

You can find it's github project here.

It's easy to install sudo $ES_HOME/bin/plugin -i mobz/elasticsearch-head and then you can open localhost:9200/_plugin/head/ in your web brower.

You should have something that looks like this :

A height of 100% for is, presumably, the height of your browser's inner window, because that is the height of its parent, the page. An auto height will be the minimum height of necessary to contain .

You have to make sure that the proxy is enabled on the server. You can do so by using the following commands:

  a2enmod proxy
  a2enmod proxy_http

  service apache2 restart

A project is not exactly the same thing as an executable jar file.

For starters, a project generally contains source code, while an executable jar file generally doesn't. Again, generally speaking, you need to export an Eclipse project to obtain a file suitable for importing.

Using moment will be much easier in this case, You could try this:

    let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days');

It will give you integer value like 1,2,5,0etc so you can easily use condition check like:

if(days < 1) {

Also, one more thing is you can get more accurate result of the time difference (in decimals like 1.2,1.5,0.7etc) to get this kind of result use this syntax:

let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days', true);

Let me know if you have any further query

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

Java supports^* covariant return types for overridden methods. This means an overridden method may have a more specific return type. That is, as long as the new return type is assignable to the return type of the method you are overriding, it's allowed.

For example:

class ShapeBuilder {
    ...
    public Shape build() {
    ....
}

class CircleBuilder extends ShapeBuilder{
    ...
    @Override
    public Circle build() {
    ....
}

This is specified in section 8.4.5 of the Java Language Specification:

Return types may vary among methods that override each other if the return types are reference types. The notion of return-type-substitutability supports covariant returns, that is, the specialization of the return type to a subtype.

A method declaration d1 with return type R1 is return-type-substitutable for another method d2 with return type R2, if and only if the following conditions hold:

• If R1 is void then R2 is void.

• If R1 is a primitive type, then R2 is identical to R1.

• If R1 is a reference type then:

  • R1 is either a subtype of R2 or R1 can be converted to a subtype of R2 by unchecked conversion (§5.1.9), or

  • R1 = |R2|

("|R2|" refers to the erasure of R2, as defined in §4.6 of the JLS.)

^{* Prior to Java 5, Java had invariant return types, which meant the return type of a method override needed to exactly match the method being overridden.}

Didn't exactly get your intent. Do check Apache Commons configuration library http://commons.apache.org/configuration/

You can have multiple values against a key as in key=value1,value2 and you can read this into an array as configuration.getAsStringArray("key")

2020 Update

This is now possible:

On Android 11, you can do

view.setWindowInsetsAnimationCallback(object : WindowInsetsAnimation.Callback {
    override fun onEnd(animation: WindowInsetsAnimation) {
        super.onEnd(animation)
        val showingKeyboard = view.rootWindowInsets.isVisible(WindowInsets.Type.ime())
        // now use the boolean for something
    }
})

You can also listen to the animation of showing/hiding the keyboard and do a corresponding transition.

I recommend reading Android 11 preview and the corresponding documentation

Before Android 11

However, this work has not been made available in a Compat version, so you need to resort to hacks.

You can get the window insets and if the bottom insets are bigger than some value you find to be reasonably good (by experimentation), you can consider that to be showing the keyboard. This is not great and can fail in some cases, but there is no framework support for that.

This is a good answer on this exact question https://stackoverflow.com/a/36259261/372076. Alternatively, here's a page giving some different approaches to achieve this pre Android 11:

https://developer.salesforce.com/docs/atlas.en-us.noversion.service_sdk_android.meta/service_sdk_android/android_detecting_keyboard.htm

Note

This solution will not work for soft keyboards and onConfigurationChanged will not be called for soft (virtual) keyboards.

You've got to handle configuration changes yourself.

http://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange

Sample:

// from the link above
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    
    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

Then just change the visibility of some views, update a field, and change your layout file.

lst *= 0

has the same effect as

lst[:] = []

It's a little simpler and maybe easier to remember. Other than that there's not much to say

The efficiency seems to be about the same

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).

Typical symptoms:

[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100

[root@host /]# netstat -plant | grep 25
tcp        0      0 :::25                       :::*                        LISTEN      1082/exim           

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

Make sure to set the Button State for .normal

extension UINavigationBar {

    func makeContent(color: UIColor) {
        let attributes: [NSAttributedString.Key: Any]? = [.foregroundColor: color]

        self.titleTextAttributes = attributes
        self.topItem?.leftBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
        self.topItem?.rightBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
    }
}

Spring source code to explain how ApplicationContextAware work
when you use ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
In AbstractApplicationContext class,the refresh() method have the following code:

// Prepare the bean factory for use in this context.
prepareBeanFactory(beanFactory);

enter this method,beanFactory.addBeanPostProcessor(new ApplicationContextAwareProcessor(this)); will add ApplicationContextAwareProcessor to AbstractrBeanFactory.

protected void prepareBeanFactory(ConfigurableListableBeanFactory beanFactory) {
        // Tell the internal bean factory to use the context's class loader etc.
        beanFactory.setBeanClassLoader(getClassLoader());
        beanFactory.setBeanExpressionResolver(new StandardBeanExpressionResolver(beanFactory.getBeanClassLoader()));
        beanFactory.addPropertyEditorRegistrar(new ResourceEditorRegistrar(this, getEnvironment()));
        // Configure the bean factory with context callbacks.
        beanFactory.addBeanPostProcessor(new ApplicationContextAwareProcessor(this));
...........

When spring initialize bean in AbstractAutowireCapableBeanFactory, in method initializeBean,call applyBeanPostProcessorsBeforeInitialization to implement the bean post process. the process include inject the applicationContext.

@Override
    public Object applyBeanPostProcessorsBeforeInitialization(Object existingBean, String beanName)
            throws BeansException {
        Object result = existingBean;
        for (BeanPostProcessor beanProcessor : getBeanPostProcessors()) {
            result = beanProcessor.postProcessBeforeInitialization(result, beanName);
            if (result == null) {
                return result;
            }
        }
        return result;
    }

when BeanPostProcessor implement Objectto execute the postProcessBeforeInitialization method,for example ApplicationContextAwareProcessor that added before.

private void invokeAwareInterfaces(Object bean) {
        if (bean instanceof Aware) {
            if (bean instanceof EnvironmentAware) {
                ((EnvironmentAware) bean).setEnvironment(this.applicationContext.getEnvironment());
            }
            if (bean instanceof EmbeddedValueResolverAware) {
                ((EmbeddedValueResolverAware) bean).setEmbeddedValueResolver(
                        new EmbeddedValueResolver(this.applicationContext.getBeanFactory()));
            }
            if (bean instanceof ResourceLoaderAware) {
                ((ResourceLoaderAware) bean).setResourceLoader(this.applicationContext);
            }
            if (bean instanceof ApplicationEventPublisherAware) {
                ((ApplicationEventPublisherAware) bean).setApplicationEventPublisher(this.applicationContext);
            }
            if (bean instanceof MessageSourceAware) {
                ((MessageSourceAware) bean).setMessageSource(this.applicationContext);
            }
            if (bean instanceof ApplicationContextAware) {
                ((ApplicationContextAware) bean).setApplicationContext(this.applicationContext);
            }
        }
    }

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

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

In case anyone needs a (nearly) ready-to-use PHP function, the following is based on this answer:

/**
 * Remove a column from a table.
 * 
 * @param string $tableName The table to remove the column from.
 * @param string $columnName The column to remove from the table.
 */
public function DropTableColumn($tableName, $columnName)
{
    // --
    // Determine all columns except the one to remove.

    $columnNames = array();

    $statement = $pdo->prepare("PRAGMA table_info($tableName);");
    $statement->execute(array());
    $rows = $statement->fetchAll(PDO::FETCH_OBJ);

    $hasColumn = false;

    foreach ($rows as $row)
    {
        if(strtolower($row->name) !== strtolower($columnName))
        {
            array_push($columnNames, $row->name);
        }
        else
        {
            $hasColumn = true;
        }
    }

    // Column does not exist in table, no need to do anything.
    if ( !$hasColumn ) return;

    // --
    // Actually execute the SQL.

    $columns = implode('`,`', $columnNames);

    $statement = $pdo->exec(
       "CREATE TABLE `t1_backup` AS SELECT `$columns` FROM `$tableName`;
        DROP TABLE `$tableName`;
        ALTER TABLE `t1_backup` RENAME TO `$tableName`;");
}

In contrast to other answers, the SQL used in this approach seems to preserve the data types of the columns, whereas something like the accepted answer seems to result in all columns to be of type TEXT.

Update 1:

The SQL used has the drawback that autoincrement columns are not preserved.

If you want to stick with the original List instead of creating a new one, you can something similar to what the Distinct() extension method does internally, i.e. use a HashSet to check for uniqueness:

HashSet<long> set = new HashSet<long>(longs.Count);
longs.RemoveAll(x => !set.Add(x));

The List class provides this convenient RemoveAll(predicate) method that drops all elements not satisfying the condition specified by the predicate. The predicate is a delegate taking a parameter of the list's element type and returning a bool value. The HashSet's Add() method returns true only if the set doesn't contain the item yet. Thus by removing any items from the list that can't be added to the set you effectively remove all duplicates.

A quick and easy solution for those who don't have much deviation from default VS settings.

Tools-->Import and Export Settings-->Yes, save my current settings-->Visual C#

I am sure the above solution would work with other default settings too. In my case something messed up with my symbol loading settings but I could not fix it even though I tried quite a few of the suggested solutions.

Here is the solution:

1. Login to DB;
2. Run a command show full processlist;to get the process id with status and query itself which causes the database hanging;
3. Select the process id and run a command KILL <pid>; to kill that process.

Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:

1. Login to MySQL;
2. Run a query Select concat('KILL ',id,';') from information_schema.processlist where user='user'; to print all processes with KILL command;
3. Copy the query result, paste and remove a pipe | sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.

I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).

When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

In my case, I have a PHP web application being served by Apache2 within the docker container that connects to a MYSQL backend database. Larry Cai's solution worked with minor modifications. I created a entrypoint.sh file within which I am managing my services. I think creating an entrypoint.sh when you have more than one command to execute when your container starts up is a cleaner way to bootstrap docker.

#!/bin/sh

set -e

echo "Starting the mysql daemon"
service mysql start

echo "navigating to volume /var/www"
cd /var/www
echo "Creating soft link"
ln -s /opt/mysite mysite

a2enmod headers
service apache2 restart

a2ensite mysite.conf
a2dissite 000-default.conf
service apache2 reload

if [ -z "$1" ]
then
    exec "/usr/sbin/apache2 -D -foreground"
else
    exec "$1"
fi

My solution to this issue running a Mac was to

1. Install Ruby and sequel similar to Macario's answer. I followed this link to help setup Ruby, mysql and sqlite3 Ruby on Rails development setup for Mac OSX

2. Install sequel

   $ gem install sequel
   

   If still required

   % gem install mysql sqlite3
   

   then used the following based of the Sequel doc bin_sequel.rdoc (see Copy Database)

   sequel -C mysql://myUserName:myPassword@host/databaseName sqlite://myConvertedDatabaseName.sqlite
   

A windows user could install Ruby and Sequel for a windows solution.

It depends on the scenario. XmlSerializer is certainly one way and has the advantage of mapping directly to an object model. In .NET 3.5, XDocument, etc. are also very friendly. If the size is very large, then XmlWriter is your friend.

For an XDocument example:

Console.WriteLine(
    new XElement("Foo",
        new XAttribute("Bar", "some & value"),
        new XElement("Nested", "data")));

Or the same with XmlDocument:

XmlDocument doc = new XmlDocument();
XmlElement el = (XmlElement)doc.AppendChild(doc.CreateElement("Foo"));
el.SetAttribute("Bar", "some & value");
el.AppendChild(doc.CreateElement("Nested")).InnerText = "data";
Console.WriteLine(doc.OuterXml);

If you are writing a large stream of data, then any of the DOM approaches (such as XmlDocument/XDocument, etc.) will quickly take a lot of memory. So if you are writing a 100 MB XML file from CSV, you might consider XmlWriter; this is more primitive (a write-once firehose), but very efficient (imagine a big loop here):

XmlWriter writer = XmlWriter.Create(Console.Out);
writer.WriteStartElement("Foo");
writer.WriteAttributeString("Bar", "Some & value");
writer.WriteElementString("Nested", "data");
writer.WriteEndElement();

Finally, via XmlSerializer:

[Serializable]
public class Foo
{
    [XmlAttribute]
    public string Bar { get; set; }
    public string Nested { get; set; }
}
...
Foo foo = new Foo
{
    Bar = "some & value",
    Nested = "data"
};
new XmlSerializer(typeof(Foo)).Serialize(Console.Out, foo);

This is a nice model for mapping to classes, etc.; however, it might be overkill if you are doing something simple (or if the desired XML doesn't really have a direct correlation to the object model). Another issue with XmlSerializer is that it doesn't like to serialize immutable types : everything must have a public getter and setter (unless you do it all yourself by implementing IXmlSerializable, in which case you haven't gained much by using XmlSerializer).

Please try this simple function

var NanValue = function (entry) {
    if(entry=="NaN") {
        return 0.00;
    } else {
        return entry;
    }
}

Kotlin Code with runOnUiThread

runOnUiThread(
        object : Runnable {
            override fun run() {
                Toast.makeText(applicationContext, "Calling from runOnUiThread()", Toast.LENGTH_SHORT)  
            }
        }
)

Redis is better.

The Pros of Redis are ,

1. It has a lot of data storage options such as string , sets , sorted sets , hashes , bitmaps
2. Disk Persistence of records
3. Stored Procedure (LUA scripting) support
4. Can act as a Message Broker using PUB/SUB

Whereas Memcache is an in-memory key value cache type system.

1. No support for various data type storages like lists , sets as in redis.
2. The major con is Memcache has no disk persistence .

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

You can use two methods in jQuery as given below-

Using jQuery :nth-child Selector You have put the position of an element as its argument which is 2 as you want to select the second li element.

$( "ul li:nth-child(2)" ).click(function(){_x000D_
  //do something_x000D_
});

Using jQuery :eq() Selector

If you want to get the exact element, you have to specify the index value of the item. A list element starts with an index 0. To select the 2nd element of li, you have to use 2 as the argument.

$( "ul li:eq(1)" ).click(function(){_x000D_
  //do something_x000D_
});

See Example: Get Second Child Element of List in jQuery

In my case above all options were already there.

Actually Boost does have such adaptor: boost::adaptors::reverse.

#include <list>
#include <iostream>
#include <boost/range/adaptor/reversed.hpp>

int main()
{
    std::list<int> x { 2, 3, 5, 7, 11, 13, 17, 19 };
    for (auto i : boost::adaptors::reverse(x))
        std::cout << i << '\n';
    for (auto i : x)
        std::cout << i << '\n';
}

Very elegant solution inspired from this one. This one uses only .Net library and does not need to use any command line or Win32 API.

Code for ready reference:

NetworkCredential theNetworkCredential = new NetworkCredential(@"domain\username", "password");
CredentialCache theNetCache = new CredentialCache();
theNetCache.Add(new Uri(@"\\computer"), "Basic", theNetworkCredential);
string[] theFolders = Directory.GetDirectories(@"\\computer\share");

If the URL works fine in the web browser on the same machine, it might be that the Java code isn't using the HTTP proxy the browser is using for connecting to the URL.

I got this error when I put a space before a comma in the parameters when calling a function.

eg, I used:

myfunction(parameter1: parameter1 , parameter2: parameter2)

Whereas it should have been:

myfunction(parameter1: parameter1, parameter2: parameter2)

Deleting the space got rid of the error message

you can use generic class:

class Wrapped<T>  {
    private T _value;

    public Action ValueChanged;

    public T Value
    {
        get => _value;

        set
        {
            _value = value;
            OnValueChanged();
        }
    }

    protected virtual void OnValueChanged() => ValueChanged?.Invoke() ;
}

and will be able to do the following:

var i = new Wrapped<int>();

i.ValueChanged += () => { Console.WriteLine("changed!"); };

i.Value = 10;
i.Value = 10;
i.Value = 10;
i.Value = 10;

Console.ReadKey();

result:

changed!
changed!
changed!
changed!
changed!
changed!
changed!

.a files are static libraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.

Simple variant:

Regex.Replace(input, @"\r\n|\r|\n", "\r\n")

For better performance:

static Regex newline_pattern = new Regex(@"\r\n|\r|\n", RegexOptions.Compiled);
[...]
    newline_pattern.Replace(input, "\r\n");

Facebook publishes the SDK on maven central :

}

PEP 3155 introduced __qualname__, which was implemented in Python 3.3.

For top-level functions and classes, the __qualname__ attribute is equal to the __name__ attribute. For nested classes, methods, and nested functions, the __qualname__ attribute contains a dotted path leading to the object from the module top-level.

It is accessible from within the very definition of a class or a function, so for instance:

class Foo:
    print(__qualname__)

will effectively print Foo. You'll get the fully qualified name (excluding the module's name), so you might want to split it on the . character.

However, there is no way to get an actual handle on the class being defined.

>>> class Foo:
...     print('Foo' in globals())
... 
False

There is also this syntax, e.g. if you want to delete the 2nd element :

array=("${array[@]:0:1}" "${array[@]:2}")

which is in fact the concatenation of 2 tabs. The first from the index 0 to the index 1 (exclusive) and the 2nd from the index 2 to the end.

I think what you are being asked to do (or perhaps asking yourself?) is take a character value which matches the name of a column in a particular dataframe (possibly also given as a character). There are two tricks here. Most people learn to extract columns with the "$" operator and that won't work inside a function if the function is passed a character vecor. If the function is also supposed to accept character argument then you will need to use the get function as well:

 df1 <- data.frame(a=1:10, b=11:20)
 mean_col <- function( dfrm, col ) mean( get(dfrm)[[ col ]] )
 mean_col("df1", "b")
 # [1] 15.5

There is sort of a semantic boundary between ordinary objects like character vectors and language objects like the names of objects. The get function is one of the functions that lets you "promote" character values to language level evaluation. And the "$" function will NOT evaluate its argument in a function, so you need to use"[[". "$" only is useful at the console level and needs to be completely avoided in functions.

This is how you can modify registry, without yes or no prompt and don't forget to run as administrator

reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\etc\etc   /v Valuename /t REG_SZ /d valuedata  /f 

Below is a real example to set internet explorer as my default browser

reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice   /v ProgId /t REG_SZ /d IE.HTTPS  /f 

/f Force: Force an update without prompting "Value exists, overwrite Y/N"

/d Data : The actual data to store as a "String", integer etc

/v Value : The value name eg ProgId

/t DataType : REG_SZ (default) | REG_DWORD | REG_EXPAND_SZ | REG_MULTI_SZ

unit tested, working as expected...

If a <script> has a src then the text content of the element will be not be executed as JS (although it will appear in the DOM).

You need to use multiple script elements.

1. a <script> to load the external script

2. a <script> to hold your inline code (with the call to the function in the external script)

   scroll_messages();

Executive summary: it's 64 bits, or larger.

unsigned long long is the same as unsigned long long int. Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits. There was no long long in C89, but apparently even MSVC supports it, so it's quite portable.

In the current C++ standard (issued in 2003), there is no long long, though many compilers support it as an extension. The upcoming C++0x standard will support it and its size will be the same as in C, so at least 64 bits.

You can get the exact size, in bytes (8 bits on typical platforms) with the expression sizeof(unsigned long long). If you want exactly 64 bits, use uint64_t, which is defined in the header <stdint.h> along with a bunch of related types (available in C99, C++11 and some current C++ compilers).

I am surprised all these instruction didn't solved my problem. Nonetheless, the diagnostic is correct (BTW, I am using Mac and Python3.6.1). So, to summarize the correct part :

• On Mac, Apple is dropping OpenSSL
• Python now uses it own set of CA Root Certificate
• Binary Python installation provided a script to install the CA Root certificate Python needs ("/Applications/Python 3.6/Install Certificates.command")
• Read "/Applications/Python 3.6/ReadMe.rtf" for details

For me, the script doesn't work, and all those certifi and openssl installation failed to fix too. Maybe because I have multiple python 2 and 3 installations, as well as many virtualenv. At the end, I need to fix it by hand.

pip install certifi   # for your virtualenv
mkdir -p /Library/Frameworks/Python.framework/Versions/3.6/etc/openssl
cp -a <your virtualenv>/site-package/certifi/cacert.pem \
  /Library/Frameworks/Python.framework/Versions/3.6/etc/openssl/cert.pem

If that still fails you. Then re/install OpenSSL as well.

port install openssl

I found a shorter and very straightforward solution which works seamlessly, and with authentication as well, using express-http-proxy:

const url = require('url');
const proxy = require('express-http-proxy');

// New hostname+path as specified by question:
const apiProxy = proxy('other_domain.com:3000/BLABLA', {
    proxyReqPathResolver: req => url.parse(req.baseUrl).path
});

And then simply:

app.use('/api/*', apiProxy);

Note: as mentioned by @MaxPRafferty, use req.originalUrl in place of baseUrl to preserve the querystring:

    forwardPath: req => url.parse(req.baseUrl).path

Update: As mentioned by Andrew (thank you!), there's a ready-made solution using the same principle:

npm i --save http-proxy-middleware

And then:

const proxy = require('http-proxy-middleware')
var apiProxy = proxy('/api', {target: 'http://www.example.org/api'});
app.use(apiProxy)

Documentation: http-proxy-middleware on Github

If you want the editor to work with git operations, setting the $EDITOR environment variable may not be enough, at least not in the case of Sublime - e.g. if you want to rebase, it will just say that the rebase was successful, but you won't have a chance to edit the file in any way, git will just close it straight away:

git rebase -i HEAD~
Successfully rebased and updated refs/heads/master.

If you want Sublime to work correctly with git, you should configure it using:

git config --global core.editor "sublime -n -w"

I came here looking for this and found the solution in this gist on github.

Under iterm2's Preferences > Profile > Keys, you click the + below Key Mappings and record a new shortcut. For Action, select Send Escape Sequence and type b or f for backwards and forwards respectively.

When I tried to record one for (Ctrl+?), I noticed in the Keyboard Shortcut field that the arrow never showed up. Turns out I had to disable the default mac's System Preferences > Keyboard > Shortcuts > Mission Control shorcuts first to get things to work, as they'll override iterm2's default shortcuts. Should be true for the standard terminal app, too.

I depends on what is the regexp language you use, but informally, it would be:

[:alpha:][:alpha:][:digit:][:digit:][:digit:][:digit:][:digit:][:digit:]

where [:alpha:] = [a-zA-Z] and [:digit:] = [0-9]

If you use a regexp language that allows finite repetitions, that would look like:

[:alpha:]{2}[:digit:]{6}

The correct syntax depends on the particular language you're using, but that is the idea.

The HTTP server doesn't send the response header back to the client until you either specify an error or else you start sending data. If you start sending data back to the client, then the server has to send the response head (which contains the status code) first. Once the header has been sent, you can no longer put a status code in the header, obviously.

Here's the usual problem. You start up the page, and send some initial tags (i.e. <head>). The server then sends those tags to the client, after first sending the HTTP response header with an assumed SUCCESS status. Now you start working on the meat of the page and discover a problem. You can not send an error at this point because the response header, which would contain the error status, has already been sent.

The solution is this: Before you generate any content at all, check if there are going to be any errors. Only then, when you have assured that there will be no problems, can you then start sending content, like the tag.

In your case, it seems like you have a login page that processes a POST request from a form. You probably throw out some initial HTML, then check if the username and password are valid. Instead, you should authenticate the user/password first, before you generate any HTML at all.

Tried the money trick above, and this works great for numerical values with two or less significant digits. I created my own function to format numbers with decimals:

CREATE FUNCTION [dbo].[fn_FormatWithCommas] 
(
    -- Add the parameters for the function here
    @value varchar(50)
)
RETURNS varchar(50)
AS
BEGIN
    -- Declare the return variable here
    DECLARE @WholeNumber varchar(50) = NULL, @Decimal varchar(10) = '', @CharIndex int = charindex('.', @value)

    IF (@CharIndex > 0)
        SELECT @WholeNumber = SUBSTRING(@value, 1, @CharIndex-1), @Decimal = SUBSTRING(@value, @CharIndex, LEN(@value))
    ELSE
        SET @WholeNumber = @value

    IF(LEN(@WholeNumber) > 3)
        SET @WholeNumber = dbo.fn_FormatWithCommas(SUBSTRING(@WholeNumber, 1, LEN(@WholeNumber)-3)) + ',' + RIGHT(@WholeNumber, 3)



    -- Return the result of the function
    RETURN @WholeNumber + @Decimal

END

If you want to wrap your text but maintain alignment then you can wrap that cell in a minipage or varwidth environment (varwidth comes from the varwidth package). Varwidth will be "as wide as it's contents but no wider than X". You can create a custom column type which acts like "p{xx}" but shrinks to fit by using

\newcolumntype{M}[1]{>{\begin{varwidth}[t]{#1}}l<{\end{varwidth}}}

which may require the array package. Then when you use something like \begin{tabular}{llM{2in}} the first two columns we be normal left-aligned and the third column will be normal left aligned but if it gets wider than 2in then the text will be wrapped.

The following parameter-mapping example passes all parameters, including path, querystring and header, through to the integration endpoint via a JSON payload

#set($allParams = $input.params())
{
  "params" : {
    #foreach($type in $allParams.keySet())
    #set($params = $allParams.get($type))
    "$type" : {
      #foreach($paramName in $params.keySet())
      "$paramName" : "$util.escapeJavaScript($params.get($paramName))"
      #if($foreach.hasNext),#end
      #end
    }
    #if($foreach.hasNext),#end
    #end
  }
}

In effect, this mapping template outputs all the request parameters in the payload as outlined as follows:

{
  "parameters" : {
     "path" : {    
       "path_name" : "path_value", 
       ...
     }
     "header" : {  
       "header_name" : "header_value",
       ...
     }
     'querystring" : {
       "querystring_name" : "querystring_value",
       ...
     }
   }
}

Another way to do this is to add the new characters to the string as follows:

Dim str As String

str = ""

To append text to your string this way:

str = str & "and this is more text"

Based on @jared-burrows' solution. For any package, but passing Context as parameter...

public static String getDataDir(Context context) throws Exception {
    return context.getPackageManager()
            .getPackageInfo(context.getPackageName(), 0)
            .applicationInfo.dataDir;
}

The easiest way to do this would be to use a filter.

You can either filter for any cells in column A that don't have a "-" and copy / paste, or (my more preferred method) filter for all cells that do have a "-" and then select all and delete - Once you remove the filter, you're left with what you need.

Hope this helps.

Concluding from above answers, Here is the exact difference between full/strictly, complete and perfect binary trees

1. Full/Strictly binary tree :- Every node except the leaf nodes have two children

2. Complete binary tree :- Every level except the last level is completely filled and all the nodes are left justified.

3. Perfect binary tree :- Every node except the leaf nodes have two children and every level (last level too) is completely filled.

It is not a good practice but even though you wish to use it you can use the singleton pattern as its good. I have used the singleton patterns in most of my project its good.

The best solution is using DATE() function and extracting yy, mm, and dd from the string with RIGHT(), MID() and LEFT() functions, the final will be some DATE(LEFT(),MID(),RIGHT()), details here

Like a lot of functions, this one can be used in many different ways to solve many different problems, I think of it as yet another tool in our toolbelts.

So far, the discussion has focused heavily on simply hiding an ID, but that is only one value, why not use it for lots of values! That is what I am doing, I use it to load up the values in a class only one view at a time, because html.beginform creates a new object and if your model object for that view already had some values passed to it, those values will be lost unless you provide a reference to those values in the beginform.

To see a great motivation for the html.hiddenfor, I recommend you see Passing data from a View to a Controller in .NET MVC - "@model" not highlighting

Have a look at the helper class: Mage_Customer_Helper_Data

To simply get the customer name, you can write the following code:-

$customerName = Mage::helper('customer')->getCustomerName();

For more information about the customer's entity id, website id, email, etc. you can use getCustomer function. The following code shows what you can get from it:-

echo "<pre>"; print_r(Mage::helper('customer')->getCustomer()->getData()); echo "</pre>";

From the helper class, you can also get information about customer login url, register url, logout url, etc.

From the isLoggedIn function in the helper class, you can also check whether a customer is logged in or not.

alert( "Size: " + $( "li" ).size() );

alert( "Size: " + $( "li" ).length );

Both .size() and .length return number of item. but size() method is deprecated (JQ 1.8). .length property can use for instead of size().

also you can use

alert($("ul").children().length);

You can check scrollHeight and clientHeight with scrollTop to scroll to bottom of div like code below.

$('#div').scroll(function (event) {_x000D_
  if ((parseInt($('#div')[0].scrollHeight) - parseInt(this.clientHeight)) == parseInt($('#div').scrollTop())) _x000D_
  {_x000D_
    console.log("this is scroll bottom of div");_x000D_
  }_x000D_
  _x000D_
});

You missed underscore in argument document_root. But it's bad idea to use serve in production. Use something like this instead:

    if os.path.exists(file_path):
        with open(file_path, 'rb') as fh:
            response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")

I would use VMs. Create an XP (or whatever) VM using VMware Workstation or similar product, and snapshot it. That is your oldest version. Then perform the upgrades one at a time, and snapshot each time. Then you can switch to any snapshot you need later, or clone independent VMs based on all the snapshots so you can run them all at once. You probably want to test on different operating systems as well as different versions, so VMs generalize that solution as well rather than some one-off solution of hacking multiple IEs to coexist on a single instance of Windows.

Swift 3 example of Ethan Strider's answer. A function that takes a hex string and returns a UIColor.
(You can enter hex strings with either format: #ffffff or ffffff)

Example:

func hexStringToUIColor (hex:String) -> UIColor {
    var cString: String = hex.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines).uppercased()

    if (cString.hasPrefix("#")) {
        if let range = cString.range(of: cString) {
            cString = cString.substring(from: cString.index(range.lowerBound, offsetBy: 1))
        }
    }

    if ((cString.characters.count) != 6) {
        return UIColor.gray
    }

    var rgbValue: UInt32 = 0
    Scanner(string: cString).scanHexInt32(&rgbValue)

    return UIColor(
        red: CGFloat((rgbValue & 0xFF0000) >> 16) / 255.0,
        green: CGFloat((rgbValue & 0x00FF00) >> 8) / 255.0,
        blue: CGFloat(rgbValue & 0x0000FF) / 255.0,
        alpha: CGFloat(1.0)
    )
}

Usage:

var color1 = hexStringToUIColor("#d3d3d3")

Just do:

SET

You can also do SET prefix to see all variables with names starting with prefix.

First of all, I'd recommend you to go through NumPy's Quickstart tutorial, which will probably help with these basic questions.

You can directly create an array from a list as:

Or from a from a nested list in the same way:

import numpy as np
a = np.array( [[2,3,4], [3,4,5]] )

• Paths are not pointing to your computer when using SQL Server Management Studio. If you start SSMS on your local machine and connect to a SQL Server instance on server X, the file C:\photo.bmp will point to hard drive C: on server X, not your machine!

I set the below config on my MVC4 and it works like a charm

<globalization uiCulture="auto" culture="auto" />

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

See it in action:

matchObj = re.search("^(?!OK|\\.).*", item)

Don't forget to put .* after negative look-ahead, otherwise you couldn't get any match ;-)

CString s="143";
int x=atoi(s);

or

CString s=_T("143");
int x=_toti(s);

atoi will work, if you want to convert CString to int.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

# Enable TCP/IP

Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable

# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433

# Modify TCP/IP properties to enable an IP address

$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }

# Restart SQL Server

Restart-Service 'MSSQL$SQLEXPRESS'

If you're at the top level - or able to cleanly get to the top level - of the thread, then just returning is nice. Throwing an exception isn't as clean, as you need to be able to check that nothing's going to catch the exception and ignore it.

The reason you need to use Thread.currentThread() in order to call interrupt() is that interrupt() is an instance method - you need to call it on the thread you want to interrupt, which in your case happens to be the current thread. Note that the interruption will only be noticed the next time the thread would block (e.g. for IO or for a monitor) anyway - it doesn't mean the exception is thrown immediately.

It will give the current location.

mMap.setMyLocationEnabled(true);
Location userLocation = mMap.getMyLocation();
        LatLng myLocation = null;
        if (userLocation != null) {
            myLocation = new LatLng(userLocation.getLatitude(),
                    userLocation.getLongitude());
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(myLocation,
                    mMap.getMaxZoomLevel()-5));

You want to know if the column is null

select * from foo where bar is null

If you want to check for some value not equal to something and the column also contains null values you will not get the columns with null in it

does not work:

select * from foo where bar <> 'value'

does work:

select * from foo where bar <> 'value' or bar is null

in Oracle (don't know on other DBMS) some people use this

select * from foo where NVL(bar,'n/a') <> 'value'

if I read the answer from tdammers correctly then in MS SQL Server this is like that

select * from foo where ISNULL(bar,'n/a') <> 'value'

in my opinion it is a bit of a hack and the moment 'value' becomes a variable the statement tends to become buggy if the variable contains 'n/a'.

In Access, you will probably find a Join is quicker unless your tables are very small:

SELECT DISTINCT Table1.Column1
FROM Table1 
LEFT JOIN Table2
ON Table1.Column1 = Table2.Column1  
WHERE Table2.Column1 Is Null

This will exclude from the list all records with a match in Table2.

If you use module with c++ code and have the same issue you could try

Build -> Refresh Linked C++ Projects

Also, you should open some file from this module and do

Build -> Make module "YourNativeLibModuleName"

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

I got this warning because I thought my column contained null strings, but on checking, it contained np.nan!

if df['column'] == '':

Changing my column to empty strings helped :)

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

To resolve the issue on a Debian/Ubuntu system modify the /etc/apache2/ports.conf settings file by adding NameVirtualHost *:443 to it. My ports.conf is the following at the moment:

# /etc/apache/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.

    NameVirtualHost *:443

    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

Furthermore ensure that 'sites-available/default-ssl' is not enabled, type a2dissite default-ssl to disable the site. While you're at it type a2dissite by itself to get a list and see if there is any other site settings that you have enabled that might be mapping onto port 443.

j = min(len(l1), len(l2))
l3 = [l1[i]+l2[i] for i in range(j)]

The index method of a list will do this for you. If you want to guarantee order, sort the list first using sorted(). Sorted accepts a cmp or key parameter to dictate how the sorting will happen:

a = [5, 4, 3]
print sorted(a).index(5)

Or:

a = ['one', 'aardvark', 'a']
print sorted(a, key=len).index('a')

The same issue faced me with XAMPP 7 and opencart Arabic 3. Replacing localhost by the actual machine name reslove the issue.

The lock event ID is 4800, and the unlock is 4801. You can find them in the Security logs. You probably have to activate their auditing using Local Security Policy (secpol.msc, Local Security Settings in Windows XP) -> Local Policies -> Audit Policy. For Windows 10 see the picture below.

Look in Description of security events in Windows 7 and in Windows Server 2008 R2 under Subcategory: Other Logon/Logoff Events.

This error means that for whatever reason the client cannot connect to the port on the computer running server script. This can be caused by few things, like lack of routing to the destination, but since you can ping the server, it should not be the case. The other reason might be that you have a firewall somewhere between your client and the server - it could be on server itself or on the client. Given your network addressing, I assume both server and client are on the same LAN, so there shouldn't be any router/firewall involved that could block the traffic. In this case, I'd try the following:

• check if you really have that port listening on the server (this should tell you if your code does what you think it should): based on your OS, but on linux you could do something like netstat -ntulp
• check from the server, if you're accepting the connections to the server: again based on your OS, but telnet LISTENING_IP LISTENING_PORT should do the job
• check if you can access the port of the server from the client, but not using the code: just us the telnet (or appropriate command for your OS) from the client

and then let us know the findings.

If you're using display:table-row etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:

<tr style="width:100%">
    <td>Type</td>
    <td style="float:right">Name</td>
</tr>

Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table, thead, tbody, etc.)

Instead, add an outer element with display:table, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats with table elements. It'll cause so many headaches.

markup:

<div class="view-table">
    <div class="view-row">
        <div class="view-type">Type</div>
        <div class="view-name">Name</div>                
    </div>
</div>

CSS:

.view-table
{
    display:table;
    width:100%;
}
.view-row,
{
    display:table-row;
}
.view-row > div
{
    display: table-cell;
}
.view-name 
{
    text-align:right;
}

select 'i like' || type_column || ' with' ect....

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments
FROM    myView

document.getElementsByName("name") will get several elements called by same name . document.getElementsByName("name")[Number] will get one of them. document.getElementsByName("name")[Number].value will get the value of paticular element.

The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.

The Facebook API limit isn't really documented, but apparently it's something like: 600 calls per 600 seconds, per token & per IP. As the site is restricted, quoting the relevant part:

After some testing and discussion with the Facebook platform team, there is no official limit I'm aware of or can find in the documentation. However, I've found 600 calls per 600 seconds, per token & per IP to be about where they stop you. I've also seen some application based rate limiting but don't have any numbers.

As a general rule, one call per second should not get rate limited. On the surface this seems very restrictive but remember you can batch certain calls and use the subscription API to get changes.

As you can access the Graph API on the client side via the Javascript SDK; I think if you travel your request for photos from the client, you won't hit any application limit as it's the user (each one with unique id) who's fetching data, not your application server (unique ID).

This may mean a huge refactor if everything you do go through a server. But it seems like the best solution if you have so many request (as it'll give a breath to your server).

Else, you can try batch request, but I guess you're already going this way if you have big traffic.

If nothing of this works, according to the Facebook Platform Policy you should contact them.

If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).

This is what I have in my UIViewController Category. Useful for many things, including getting first responder. Blocks are great!

"SINGLESIGNON"

I checked your code and seems to be no problem at all. please make sure Image commandArgument getting value. check it first binding in label whether you are getting value.

However, here is sample which I'm using in my project

<asp:GridView ID="GridViewUserScraps" ItemStyle-VerticalAlign="Top" AutoGenerateColumns="False" Width="100%" runat="server" OnRowCommand="GridViews_RowCommand" >
        <Columns>
            <asp:TemplateField SortExpression="SendDate">
                <ItemTemplate>
                <asp:Button ID="btnPost" CssClass="submitButton" Text="Comment" runat="server" CommandName="Comment" CommandArgument='<%#Eval("ScrapId")+","+ Eval("UserId")%>' />

                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

first bind the GridView.

public void GetData()
{
   //bind ur GridView
   GridViewUserScraps.DataSource = dt;
   GridViewUserScraps.DataBind();
}

protected void GridViews_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Comment")
    {
        string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
        string scrapid = commandArgs[0];
        string uid = commandArgs[1];
    }
}

In cases where you do not have access to the derived class source, but need all the source of the derived class besides the current method, then I would recommended you should also do a derived class and call the implementation of the derived class.

Here is an example:

//No access to the source of the following classes
public class Base
{
     public virtual void method1(){ Console.WriteLine("In Base");}
}
public class Derived : Base
{
     public override void method1(){ Console.WriteLine("In Derived");}
     public void method2(){ Console.WriteLine("Some important method in Derived");}
}

//Here should go your classes
//First do your own derived class
public class MyDerived : Base
{         
}

//Then derive from the derived class 
//and call the bass class implementation via your derived class
public class specialDerived : Derived
{
     public override void method1()
     { 
          MyDerived md = new MyDerived();
          //This is actually the base.base class implementation
          MyDerived.method1();  
     }         
}

def player(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over: 
        computer(game_over)  #We are only going to do this if check_winner comes back as False

def check_winner(): 
    check something
    #here needs to be an if / then statement deciding if the game is over, return True if over, false if not
    if score == 100:
        return True
    else:
        return False

def computer(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over:
        player(game_over) #We are only going to do this if check_winner comes back as False

game_over = False   #We need a variable to hold wether the game is over or not, we'll start it out being false.
player(game_over)   #Start your loops, sending in the status of game_over

Above is a pretty simple example... I made up a statement for check_winner using score = 100 to denote the game being over.

You will want to use similar method of passing score into check_winner, using game_over = check_winner(score). Then you can create a score at the beginning of your program and pass it through to computer and player just like game_over is being handled.

Using jQuery:

$('#play-pause').click(function(){
  if ( $('#video-over').css('visibility') == 'hidden' )
    $('#video-over').css('visibility','visible');
  else
    $('#video-over').css('visibility','hidden');
});

Base URL in JavaScript

Here is simple function for your project to get base URL in JavaScript.

// base url
function base_url() {
    var pathparts = location.pathname.split('/');
    if (location.host == 'localhost') {
        var url = location.origin+'/'+pathparts[1].trim('/')+'/'; // http://localhost/myproject/
    }else{
        var url = location.origin; // http://stackoverflow.com
    }
    return url;
}

You can use below as an alternative.

1. Month to month number:

from time import strptime

strptime('Feb','%b').tm_mon

2. Month number to month:

import calendar

calendar.month_abbr[2] or calendar.month[2]

Python compiles the .py and saves files as .pyc so it can reference them in subsequent invocations.

There's no harm in deleting them, but they will save compilation time if you're doing lots of processing.

I strongly recommend using Joda Time http://joda-time.sourceforge.net/faq.html

I had this issue and realized I was using a different account from the one whose repo it was. Logging in as the original user resolved the issue.

I have faced same issue after install macOS Catalina. I had try below command and its working.

sudo gem update

I had a similar problem on OSX but tried to play around with double and single quotes. For your case, you could try something like this

$query = 'SELECT * FROM "sf_bands"'; // NOTE: double quotes on "sf_Bands"

Did you try to specify resource only in context.xml

<Resource name="jdbc/PollDatasource" auth="Container" type="javax.sql.DataSource"
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby://localhost:1527/poll_database;create=true"
username="suhail" password="suhail"
maxActive="20" maxIdle="10" maxWait="-1" />

and remove <resource-ref> section from web.xml?

In one project I've seen configuration without <resource-ref> section in web.xml and it worked.

It's an educated guess, but I think <resource-ref> declaration of JNDI resource named jdbc/PollDatasource in web.xml may override declaration of resource with same name in context.xml and the declaration in web.xml is missing both driverClassName and url hence the NPEs for that properties.

If you are developing a command line application, you can also use Console.ReadLine() at the end of your code to wait for the 'Enter' keypress before closing the console window so that you can read your output.

On Linux, you can use ldconfig, which maintains the ld.so configuration and cache, to print out the directories search by ld.so with

ldconfig -v 2>/dev/null | grep -v ^$'\t'

ldconfig -v prints out the directories search by the linker (without a leading tab) and the shared libraries found in those directories (with a leading tab); the grep gets the directories. On my machine, this line prints out

/usr/lib64/atlas:
/usr/lib/llvm:
/usr/lib64/llvm:
/usr/lib64/mysql:
/usr/lib64/nvidia:
/usr/lib64/tracker-0.12:
/usr/lib/wine:
/usr/lib64/wine:
/usr/lib64/xulrunner-2:
/lib:
/lib64:
/usr/lib:
/usr/lib64:
/usr/lib64/nvidia/tls: (hwcap: 0x8000000000000000)
/lib/i686: (hwcap: 0x0008000000000000)
/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib/sse2: (hwcap: 0x0000000004000000)
/usr/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib64/sse2: (hwcap: 0x0000000004000000)

The first paths, without hwcap in the line, are either built-in or read from /etc/ld.so.conf. The linker can then search additional directories under the basic library search path, with names like sse2 corresponding to additional CPU capabilities. These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.

One final note: using -p instead of -v above searches the ld.so cache instead.

The accepted answer has some holes in it. The beauty of the SparseArray is that it allows gaps in the indeces. So, we could have two maps like so, in a SparseArray...

(0,true)
(250,true)

Notice the size here would be 2. If we iterate over size, we will only get values for the values mapped to index 0 and index 1. So the mapping with a key of 250 is not accessed.

for(int i = 0; i < sparseArray.size(); i++) {
   int key = sparseArray.keyAt(i);
   // get the object by the key.
   Object obj = sparseArray.get(key);
}

The best way to do this is to iterate over the size of your data set, then check those indeces with a get() on the array. Here is an example with an adapter where I am allowing batch delete of items.

for (int index = 0; index < mAdapter.getItemCount(); index++) {
     if (toDelete.get(index) == true) {
        long idOfItemToDelete = (allItems.get(index).getId());
        mDbManager.markItemForDeletion(idOfItemToDelete);
        }
    }

I think ideally the SparseArray family would have a getKeys() method, but alas it does not.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

I realize this was asked several months ago, but I have an addition to samccone's answer which is more succinct but I don't have the rep to add as a comment!

Instead of:

(123456789).toString(10).split("").map(function(t){return parseInt(t)})

Consider:

(123456789).toString(10).split("").map(Number)

something like this will work too:

String.Format("{0:P}", decimal.Parse(Resellers.Fee)).Replace(".00", "")

The problem is that you have a circular import: in app.py

from mod_login import mod_login

in mod_login.py

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

If you do not have admin-rights, it can also be helpful to open the Rprofile.site-file located in \R-3.1.0\etc and add:

.First <- function(){
  .libPaths("your path here")
}

This evaluates the .libPath() command directly at start

$total=0;
foreach($group as $key=>$value)
{
   echo $key. " = " .$value. "<br>"; 
   $total+= $value;
}
echo $total;

I was getting undefined after setting a system env var. When I put APP_VERSION in the User env var, then I can display the value from node via process.env.APP_VERSION

For .NET Core, add System.Configuration.ConfigurationManager from NuGet manager.
And read appSetting from App.config

<appSettings>
  <add key="appSetting1" value="1000" />
</appSettings>

Add System.Configuration.ConfigurationManager from NuGet Manager

ConfigurationManager.AppSettings.Get("appSetting1")

DateTime startDate = new DateTime(2009, 3, 10);
DateTime stopDate = new DateTime(2009, 3, 26);
int interval = 3;

for (DateTime dateTime=startDate;
     dateTime < stopDate; 
     dateTime += TimeSpan.FromDays(interval))
{

}

If you already have the figure object use:

f.set_figheight(15)
f.set_figwidth(15)

But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

It is actually very simple. You don't have to go through a lot of stuff. Just run the following command in terminal and follow on-screen instructions.

sudo mysql_secure_installation

Try:

james.*jack

If you want both at the same time, then or them:

james.*jack|jack.*james

Intl.NumberFormat

Native JS function. Supported by IE11, Edge, latest Safari, Chrome, Firefox, Opera, Safari on iOS and Chrome on Android.

var number = 3500;

console.log(new Intl.NumberFormat().format(number));
// ? '3,500' if in US English locale

Just put this code in KeyTyped event:

    if ((jtextField.getText() + evt.getKeyChar()).length() > 20) {
        evt.consume();
    }

Where "20" is the maximum number of characters that you want.

@papigee should work on Windows 10 just fine. I'm using the integrated VSCode terminal with git bash and this always works for me.

winpty docker exec -it <container-id> //bin//sh

SELECT CONVERT(varchar(11),Getdate(),105)

I think sometimes stupid mistakes can give us this error.

<div id="#main"> <--- id with hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

To

<div id="main"> <--- id without hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

Have you checked Arrays.asList(); see API

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

In app store connect now if we are using ads in our app then we will answer as yes to Does this app use the Advertising Identifier (IDFA)?

further 3 questions will be asked as

if your using just admob then check the first one and leave other two unchecked. Other two options (2nd , 3rd ) will be checked if your using app flyer to show ads. all options are explained with detail here

In Swift both 3&4

 func removeImageLocalPath(localPathName:String) {
            let filemanager = FileManager.default
            let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask,true)[0] as NSString
            let destinationPath = documentsPath.appendingPathComponent(localPathName)
 do {
        try filemanager.removeItem(atPath: destinationPath)
        print("Local path removed successfully")
    } catch let error as NSError {
        print("------Error",error.debugDescription)
    }
    }

or This method can delete all local file

func deletingLocalCacheAttachments(){
        let fileManager = FileManager.default
        let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
        do {
            let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
            if fileURLs.count > 0{
                for fileURL in fileURLs {
                    try fileManager.removeItem(at: fileURL)
                }
            }
        } catch {
            print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
        }
    }

Here's another way of attaching the event based on W3C DOM Level 2 Events Specification:

  transport_select.addEventListener(
     'change',
     function() { toggleSelect(this.id); },
     false
  );

This is the answer if someone want to know

if (Date.now() >= exp * 1000) {
  return false;
}
