In addition to the --routines flag you will need to grant the backup user permissions to read the stored procedures:

GRANT SELECT ON `mysql`.`proc` TO <backup user>@<backup host>;

My minimal set of GRANT privileges for the backup user are:

GRANT USAGE ON *.* TO ...
GRANT SELECT, LOCK TABLES ON <target_db>.* TO ...
GRANT SELECT ON `mysql`.`proc` TO ...

    while(i<10){
               $('#Postsoutput').prepend('<div id="first'+i+'">'+i+'</div>');
               /* get the dynamic Div*/
               $('#first'+i).hide(1000);
               $('#first'+i).show(1000);
                i++;
                }

This one never failed me:

one.sh:

LFILE=/tmp/one-`echo "$@" | md5sum | cut -d\  -f1`.pid
if [ -e ${LFILE} ] && kill -0 `cat ${LFILE}`; then
   exit
fi

trap "rm -f ${LFILE}; exit" INT TERM EXIT
echo $$ > ${LFILE}

$@

rm -f ${LFILE}

cron job:

* * * * * /path/to/one.sh <command>

To support language like Hindi which can contain /p{Mark} as well in between language characters. My solution is ^[\p{L}\p{M}]+([\p{L}\p{Pd}\p{Zs}'.]*[\p{L}\p{M}])+$|^[\p{L}\p{M}]+$

You can find all the test cases for this here https://regex101.com/r/3XPOea/1/tests

I had this problem. I debugged using node-inspector and saw that from the node_modules folder where the express source files were, ejs was not installed. So I installed it there and it worked.

npm install -g ejs didn't put it where I expected it to despite NODE_PATH being set to the same node_modules folder. Prob doing it wrong, just started with node.

I liked the "START /W" answer, though for my situation I found something even more basic. My processes were console applications. And in my ignorance I thought I would need something special in BAT syntax to make sure that the 1st one completed before the 2nd one started. However BAT appears to make a distinction between console apps and windows apps, and it executes them a little differently. The OP shows that window apps will get launched as an asynchronous call from BAT. But for console apps, that are invoked synchronously, inside the same command window as the BAT itself is running in.

For me it was actually better not to use "START /W", because everything could run inside one command window. The annoying thing about "START /W" is that it will spawn a new command window to execute your console application in.

I played with JMeter. One think it could not not test was ASP.NET Webforms. The viewstate broke my tests. I am not shure why, but there are a couple of tools out there that dont handle viewstate right. My current project is ASP.NET MVC and JMeter works well with it.

In my expression, count(enddate) counts how many rows where the enddate column is not null. The count(*) expression counts total rows. By comparing, you can easily tell if any value in the enddate column contains null. If they are identical, then max(enddate) is the result. Otherwise the case will default to returning null which is also the answer. This is a very popular way to do this exact check.

SELECT recordid, 
MIN(startdate), 
case when count(enddate) = count(*) then max(enddate) end
FROM tmp 
GROUP BY recordid

The solution is:

NameVirtualHost *:80
Listen 80

(...)

<VirtualHost *:80>
    ServerName host1
    DocumentRoot /someDir
</VirtualHost>

<VirtualHost *:80>
    ServerName host2
    DocumentRoot /someOtherDir
</VirtualHost>

<VirtualHost *:80>
    ServerName aaaa.com
    DocumentRoot /defaultDir
</VirtualHost>

In my case, to work, I created a VirtualHost (n.e. VirtualHost per CNAME) called aaaa.com since I have different files for different VirtualHosts and knowing that Apache reads them in alphabetical order.

StudentList studentList = mapper.readValue(jsonString,StudentList.class);

Change this to this one

StudentList studentList = mapper.readValue(jsonString, new TypeReference<List<Student>>(){});

This could be a issue in mvn home path in IntellijIdea IDE. For me it worked out when I set the mvn home directory correctly.

See the notes at http://www.php.net/manual/en/function.ereg.php:

Note:

As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice. See the list of differences for help on converting to PCRE.

Note:

preg_match(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to ereg().

Use this instead:

<?
session_start();
session_unset();
session_destroy();

header("location:home.php");
exit();
?>

You can also use the following instruction:

Reserved.objects.filter(client=client_id).order_by('check_in').reverse()

^{Note Wording changed in response to the commments. Thanks @slekse}
That is not an error, it is a warning. It means the branch you are about to delete contains commits that are not reachable from any of: its upstream branch, or HEAD (currently checked out revision). In other words, when you might lose commits¹.

In practice it means that you probably amended, rebased or filtered commits and they don't seem identical.

Therefore you could avoid the warning by checking out a branch that does contain the commits that you're about un-reference by deleting that other branch.²

You will want to verify that you in fact aren't missing any vital commits:

git log --graph --left-right --cherry-pick --oneline master...experiment

This will give you a list of any nonshared between the branches. In case you are curious, there might be a difference without --cherry-pick and this difference could well be the reason for the warning you get:

--cherry-pick

Omit any commit that introduces the same change as another commit on the "other side" when the set of commits are limited with symmetric difference. For example, if you have two branches, A and B, a usual way to list all commits on only one side of them is with --left-right, like the example above in the description of that option. It however shows the commits that were cherry-picked from the other branch (for example, "3rd on b" may be cherry-picked from branch A). With this option, such pairs of commits are excluded from the output.

¹ they're really only garbage collected after a while, by default. Also, the git-branch command does not check the revision tree of all branches. The warning is there to avoid obvious mistakes.

² (My preference here is to just force the deletion instead, but you might want to have the extra reassurance).

Convert your string to DateTime and then use DateTime.ToString("yyyy-MM-dd");

DateTime temp = DateTime.ParseExact(sourceDate, "dd-MM-yyyy", CultureInfo.InvariantCulture);
string str = temp.ToString("yyyy-MM-dd");

The other li elements are not siblings of the a element.

$('#menu li a').on('click', function(){
    $(this).addClass('current').parent().siblings().children().removeClass('current');
}); 

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

A simplified version of SLaks' answer also works:

if ('abcdefghij'.indexOf(str) >= 0) {
    // Do something
}

....since strings are sort of arrays themselves. :)

If needed, implement the indexof function for Internet Explorer as described before me.

There is no such thing as a byte or short literal. You need to cast to short using (short)100

There is no such file open mode as "wr" in your code:

fopen("logs.txt", "wr") 

The file open modes in PHP http://php.net/manual/en/function.fopen.php is the same as in C: http://www.cplusplus.com/reference/cstdio/fopen/

There are the following main open modes "r" for read, "w" for write and "a" for append, and you cannot combine them. You can add other modifiers like "+" for update, "b" for binary. The new C standard adds a new standard subspecifier ("x"), supported by PHP, that can be appended to any "w" specifier (to form "wx", "wbx", "w+x" or "w+bx"/"wb+x"). This subspecifier forces the function to fail if the file exists, instead of overwriting it.

Besides that, in PHP 5.2.6, the 'c' main open mode was added. You cannot combine 'c' with 'a', 'r', 'w'. The 'c' opens the file for writing only. If the file does not exist, it is created. If it exists, it is neither truncated (as opposed to 'w'), nor the call to this function fails (as is the case with 'x'). 'c+' Open the file for reading and writing; otherwise it has the same behavior as 'c'.

Additionally, and in PHP 7.1.2 the 'e' option was added that can be combined with other modes. It set close-on-exec flag on the opened file descriptor. Only available in PHP compiled on POSIX.1-2008 conform systems.

So, for the task as you have described it, the best file open mode would be 'a'. It opens the file for writing only. It places the file pointer at the end of the file. If the file does not exist, it attempts to create it. In this mode, fseek() has no effect, writes are always appended.

Here is what you need, as has been already pointed out above:

fopen("logs.txt", "a") 

Both do different things.

The first creates an object with automatic storage duration. It is created, used, and then goes out of scope when the current block ({ ... }) ends. It's the simplest way to create an object, and is just the same as when you write int x = 0;

The second creates an object with dynamic storage duration and allows two things:

• Fine control over the lifetime of the object, since it does not go out of scope automatically; you must destroy it explicitly using the keyword delete;

• Creating arrays with a size known only at runtime, since the object creation occurs at runtime. (I won't go into the specifics of allocating dynamic arrays here.)

Neither is preferred; it depends on what you're doing as to which is most appropriate.

Use the former unless you need to use the latter.

Your C++ book should cover this pretty well. If you don't have one, go no further until you have bought and read, several times, one of these.

Good luck.

Your original code is broken, as it deletes a char array that it did not new. In fact, nothing newd the C-style string; it came from a string literal. deleteing that is an error (albeit one that will not generate a compilation error, but instead unpredictable behaviour at runtime).

Usually an object should not have the responsibility of deleteing anything that it didn't itself new. This behaviour should be well-documented. In this case, the rule is being completely broken.

List newStream = list.stream().sorted(Collections.reverseOrder()).collect(Collectors.toList());
        newStream.forEach(System.out::println);

You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.

<resource-ref> introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.

So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB name. The container finds that web.xml has a <resource-ref> element for jdbc/primaryDB, so it will look into the container-specific configuration, that contains something similar to the following:

<resource-ref>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>

Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer.

The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.

Use these:

webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setDisplayZoomControls(false);

In Sequelize version 5 you might also can use this way (full use Operator Sequelize) :

var condition = 
{ 
  [Op.or]: [ 
   { 
     LastName: {
      [Op.eq]: "Doe"
      },
    },
   { 
     FirstName: {
      [Op.or]: ["John", "Jane"]
      }
   },
   {
      Age:{
        [Op.gt]: 18
      }
    }
 ]
}

And then, you must include this :

const Op = require('Sequelize').Op

and pass it in :

Student.findAll(condition)
.success(function(students){ 
//
})

It could beautifully generate SQL like this :

"SELECT * FROM Student WHERE LastName='Doe' OR FirstName in ("John","Jane") OR Age>18"

We got the error:

GET http://localhost/pathToWebSite/somePage.aspx raised an http.status: 0 error

That call is made from windows task that calls a VBS file, so to troubleshoot the problem, pointed a browser to the url and we get a Privacy Error:

Your connection is not private

Attackers might be trying to steal your information from localhost (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID

Automatically report details of possible security incidents to Google. Privacy policy Back to safety This server could not prove that it is localhost; its security certificate is from *.ourdomain.com. This may be caused by a misconfiguration or an attacker intercepting your connection. Learn more.

This is because we have a IIS URL Rewrite rule set to force connections use https. That rule diverts http://localhost to https://localhost but our SSL certificate is based on an outside facing domain name not localhost, thus the error which is reported as status code 0. So a Privacy error could be a very obscure reason for this status code 0.

In our case the solution was to add an exception to the rule for localhost and allow http://localhost/pathToWebSite/somePage.aspx to use http. Obscure, yes, but I'll run into this next year and now I'll find my answer in a google search.

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

Although, there are many useful answers. Whereas, just to add another way to it. You can also use

git shortlog --author="<author name>" --format="%h %s"

It will show the output in the grouped manner:

<Author Name> (5):
  4da3975f dependencies upgraded
  49172445 runtime dependencies resolved
  bff3e127 user-service, kratos, and guava dependencies upgraded
  414b6f1e dropwizard :- service, rmq and db-sharding depedencies upgraded
  a96af8d3 older dependecies removed

Here, total of 5 commits are done by <Author Name> under the current branch. Whereas, you can also use --all to enforce the search everywhere (all the branches) in the git repository.

One catch: git internally tries to match an input <author name> with the name and email of the author in the git database. It is case-sensitive.

To make an image responsive use the following:

CSS

.responsive-image {
        width: 950px;//Any width you want to set the image to.
        max-width: 100%;
        height: auto;
}

HTML

<img class="responsive-image" src="IMAGE URL">

I had the same issue, but I have resolved it the next:

1) Install jdk1.8...

2) In AndroidStudio File->Project Structure->SDK Location, select your directory where the JDK is located, by default Studio uses embedded JDK but for some reason it produces error=216.

3) Click Ok.

One more solution when you want to use data from any sell ( in the key C3)

=SUMIF(Sheet6!M:M;CONCATENATE("<";TEXT(C3;"dd.mm.yyyy"));Sheet6!L:L)

To those that are incline to use GUI:

Click Right mouse button on procecdure name then select Test

Then in new window you will see script generated just add the parameters and click on Start Debugger or F9

Hope this saves you some time.

You can run easy_install to install python packages in your home directory even without root access. There's a standard way to do this using site.USER_BASE which defaults to something like $HOME/.local or $HOME/Library/Python/2.7/bin and is included by default on the PYTHONPATH

To do this, create a .pydistutils.cfg in your home directory:

cat > $HOME/.pydistutils.cfg <<EOF
[install]
user=1
EOF

Now you can run easy_install without root privileges:

easy_install boto

Alternatively, this also lets you run pip without root access:

pip install boto

This works for me.

Is there maybe a way to grab the rendered page from the internet explorer rendering engine and send it to a PDF-Printer tool automatically?

This is how ActivePDF works, which is good means that you know what you'll get, and it actually has reasonable styling support.

It is also one of the few packages I found (when looking a few years back) that actually supports the various page-break CSS commands.

Unfortunately, the ActivePDF software is very frustrating - since it has to launch the IE browser in the background for conversions it can be quite slow, and it is not particularly stable either.

There is a new version currently in Beta which is supposed to be much better, but I've not actually had a chance to try it out, so don't know how much of an improvement it is.

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

TO CHECK IF AN URL IS UP OR NOT

The code in your question can be rewritten as to a working version:

function send($packet=NULL, $url) {
// Do whatever you wanted to do with $packet
// The below two lines of code will let you know if https url is up or not
$command = 'curl -k '.$url;
return exec($command, $output, $retValue);
}

I would recommend to use Calendar object and Locale since month names are different for different languages:

// index can be 0 - 11
private String getMonthName(final int index, final Locale locale, final boolean shortName)
{
    String format = "%tB";

    if (shortName)
        format = "%tb";

    Calendar calendar = Calendar.getInstance(locale);
    calendar.set(Calendar.MONTH, index);
    calendar.set(Calendar.DAY_OF_MONTH, 1);

    return String.format(locale, format, calendar);
}

Example for full month name:

System.out.println(getMonthName(0, Locale.US, false));

Result: January

Example for short month name:

System.out.println(getMonthName(0, Locale.US, true));

Result: Jan

You can also start eclipse within a shell.

You export the enronment, before calling eclipse.

Example :

#!/bin/bash
export MY_VAR="ADCA"
export PATH="/home/lala/bin;$PATH"
$ECLIPSE_HOME/eclipse -data $YOUR_WORK_SPACE_PATH

Then you can have multiple instances on eclipse with their own custome environment including workspace.

multiprocessing is not like threading. Each child process will get a copy of the main process's memory. Generally state is shared via communication (pipes/sockets), signals, or shared memory.

Multiprocessing makes some abstractions available for your use case - shared state that's treated as local by use of proxies or shared memory: http://docs.python.org/library/multiprocessing.html#sharing-state-between-processes

Relevant sections:

• http://docs.python.org/library/multiprocessing.html#shared-ctypes-objects
• http://docs.python.org/library/multiprocessing.html#module-multiprocessing.managers

Although many correct and detailed explanations are available. but here is my C implementation:

#include<stdio.h>
#include<conio.h> 

main()
{
int pk,qd,am,no,c=0;
printf("\n Enter the Number U want to Find");
scanf("%d",&no);
for(pk=2;pk<=1000;pk++)
{
am=0;
for(qd=2;qd<=pk/2;qd++)
{
if(pk%qd==0)
{
am=1;
break;
}}
if(am==0)
c++;
if(c==no)
{
printf("%d",pk);
break;
}}
getch();
return 0;
}

Use the javac program that comes with the JDK (visit java.sun.com if you don't have it). The installer does not automatically add javac to your system path, so you'll need to add the bin directory of the installed path to your system path before you can use it easily.

>>> response='bababa'
...  if "K" in response.text:
...     raise ValueError("Not found")

The nohup command only writes to nohup.out if the output would otherwise go to the terminal. If you have redirected the output of the command somewhere else - including /dev/null - that's where it goes instead.

 nohup command >/dev/null 2>&1   # doesn't create nohup.out

If you're using nohup, that probably means you want to run the command in the background by putting another & on the end of the whole thing:

 nohup command >/dev/null 2>&1 & # runs in background, still doesn't create nohup.out

On Linux, running a job with nohup automatically closes its input as well. On other systems, notably BSD and macOS, that is not the case, so when running in the background, you might want to close input manually. While closing input has no effect on the creation or not of nohup.out, it avoids another problem: if a background process tries to read anything from standard input, it will pause, waiting for you to bring it back to the foreground and type something. So the extra-safe version looks like this:

nohup command </dev/null >/dev/null 2>&1 & # completely detached from terminal 

Note, however, that this does not prevent the command from accessing the terminal directly, nor does it remove it from your shell's process group. If you want to do the latter, and you are running bash, ksh, or zsh, you can do so by running disown with no argument as the next command. That will mean the background process is no longer associated with a shell "job" and will not have any signals forwarded to it from the shell. (Note the distinction: a disowned process gets no signals forwarded to it automatically by its parent shell - but without nohup, it will still receive a HUP signal sent via other means, such as a manual kill command. A nohup'ed process ignores any and all HUP signals, no matter how they are sent.)

Explanation:

In Unixy systems, every source of input or target of output has a number associated with it called a "file descriptor", or "fd" for short. Every running program ("process") has its own set of these, and when a new process starts up it has three of them already open: "standard input", which is fd 0, is open for the process to read from, while "standard output" (fd 1) and "standard error" (fd 2) are open for it to write to. If you just run a command in a terminal window, then by default, anything you type goes to its standard input, while both its standard output and standard error get sent to that window.

But you can ask the shell to change where any or all of those file descriptors point before launching the command; that's what the redirection (<, <<, >, >>) and pipe (|) operators do.

The pipe is the simplest of these... command1 | command2 arranges for the standard output of command1 to feed directly into the standard input of command2. This is a very handy arrangement that has led to a particular design pattern in UNIX tools (and explains the existence of standard error, which allows a program to send messages to the user even though its output is going into the next program in the pipeline). But you can only pipe standard output to standard input; you can't send any other file descriptors to a pipe without some juggling.

The redirection operators are friendlier in that they let you specify which file descriptor to redirect. So 0<infile reads standard input from the file named infile, while 2>>logfile appends standard error to the end of the file named logfile. If you don't specify a number, then input redirection defaults to fd 0 (< is the same as 0<), while output redirection defaults to fd 1 (> is the same as 1>).

Also, you can combine file descriptors together: 2>&1 means "send standard error wherever standard output is going". That means that you get a single stream of output that includes both standard out and standard error intermixed with no way to separate them anymore, but it also means that you can include standard error in a pipe.

So the sequence >/dev/null 2>&1 means "send standard output to /dev/null" (which is a special device that just throws away whatever you write to it) "and then send standard error to wherever standard output is going" (which we just made sure was /dev/null). Basically, "throw away whatever this command writes to either file descriptor".

When nohup detects that neither its standard error nor output is attached to a terminal, it doesn't bother to create nohup.out, but assumes that the output is already redirected where the user wants it to go.

The /dev/null device works for input, too; if you run a command with </dev/null, then any attempt by that command to read from standard input will instantly encounter end-of-file. Note that the merge syntax won't have the same effect here; it only works to point a file descriptor to another one that's open in the same direction (input or output). The shell will let you do >/dev/null <&1, but that winds up creating a process with an input file descriptor open on an output stream, so instead of just hitting end-of-file, any read attempt will trigger a fatal "invalid file descriptor" error.

I've a workaround for NullPointerException when remove fragment in on DestoryView, Just put your code in onStop() not onDestoryView. It works fine!

@Override
public void onStop() {
    super.onStop();
    if (mMap != null) {
        MainActivity.fragmentManager.beginTransaction()
                .remove(MainActivity.fragmentManager.findFragmentById(R.id.location_map)).commit();
        mMap = null;
    }
}

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.

geonames is nice. an export tool based on geonames:

there's also the excellent pycountry module:

The newer subprocess.check_output and similar commands are supposed to replace os.system. See this page for details. While I can't test this on Windows (because I don't have access to any Windows machines), the following should work:

from subprocess import check_output
check_output("dir C:", shell=True)

check_output returns a string of the output from your command. Alternatively, subprocess.call just runs the command and returns the status of the command (usually 0 if everything is okay).

Also note that, in python 3, that string output is now bytes output. If you want to change this into a string, you need something like

from subprocess import check_output
check_output("dir C:", shell=True).decode()

If necessary, you can tell it the kind of encoding your program outputs. The default is utf-8, which typically works fine, but other standard options are here.

Also note that @bluescorpion says in the comments that Windows 10 needs a trailing backslash, as in check_output("dir C:\\", shell=True). The double backslash is needed because \ is a special character in python, so it has to be escaped. (Also note that even prefixing the string with r doesn't help if \ is the very last character of the string — r"dir C:\" is a syntax error, though r"dir C:\ " is not.)

Edit 2017:

use ggplot and theme(legend.position = ""):

library(ggplot2)
library(reshape2)

set.seed(121)
a=sample(1:100,5)
b=sample(1:100,5)
c=sample(1:100,5)

df = data.frame(number = 1:5,a,b,c)
df_long <- melt(df,id.vars = "number")
ggplot(data=df_long,aes(x = number,y=value, colour=variable)) +geom_line() +
theme(legend.position="bottom")

Original answer 2012: Put the legend on the bottom:

set.seed(121)
a=sample(1:100,5)
b=sample(1:100,5)
c=sample(1:100,5)

dev.off()

layout(rbind(1,2), heights=c(7,1))  # put legend on bottom 1/8th of the chart

plot(a,type='l',ylim=c(min(c(a,b,c)),max(c(a,b,c))))
lines(b,lty=2)
lines(c,lty=3,col='blue')

# setup for no margins on the legend
par(mar=c(0, 0, 0, 0))
# c(bottom, left, top, right)
plot.new()
legend('center','groups',c("A","B","C"), lty = c(1,2,3),
       col=c('black','black','blue'),ncol=3,bty ="n")

for (Int32 i = 1; i < dt_pattern.Rows.Count - 1; i++){ double yATmax = ToDouble(dt_pattern.Rows[i]["Ampl"].ToString()) + AT; }

Refer to example at this link. It may be help to you.

Use CDATA tags:

 <![CDATA[
   This is some text with ampersands & other funny characters. >>
 ]]>

Improving a little the answer of marvin:

RESULT=$(awk "BEGIN {printf \"%.2f\",${IMG_WIDTH}/${IMG2_WIDTH}}")

bc doesn't come always as installed package.

Best and shortest solution. It will work for any group of radios (with the same name).

$(document).ready(function(){
    $("input:radio:checked").data("chk",true);
    $("input:radio").click(function(){
        $("input[name='"+$(this).attr("name")+"']:radio").not(this).removeData("chk");
        $(this).data("chk",!$(this).data("chk"));
        $(this).prop("checked",$(this).data("chk"));
        $(this).button('refresh'); // in case you change the radio elements dynamically
    });
});

Okay, so if later on down the line the issue is that you have a query that's greater than the allowable size (which may happen if it keeps growing) you're going to have to break it into chunks and execute the string values. So, let's say you have a stored procedure like the following:

CREATE PROCEDURE ExecuteMyHugeQuery
    @SQL VARCHAR(MAX) -- 2GB size limit as stated by Martin Smith
AS
BEGIN
    -- Now, if the length is greater than some arbitrary value
    -- Let's say 2000 for this example
    -- Let's chunk it
    -- Let's also assume we won't allow anything larger than 8000 total
    DECLARE @len INT
    SELECT @len = LEN(@SQL)

    IF (@len > 8000)
    BEGIN
        RAISERROR ('The query cannot be larger than 8000 characters total.',
                   16,
                   1);
    END

    -- Let's declare our possible chunks
    DECLARE @Chunk1 VARCHAR(2000),
            @Chunk2 VARCHAR(2000),
            @Chunk3 VARCHAR(2000),
            @Chunk4 VARCHAR(2000)

    SELECT @Chunk1 = '',
           @Chunk2 = '',
           @Chunk3 = '',
           @Chunk4 = ''

    IF (@len > 2000)
    BEGIN
        -- Let's set the right chunks
        -- We already know we need two chunks so let's set the first
        SELECT @Chunk1 = SUBSTRING(@SQL, 1, 2000)

        -- Let's see if we need three chunks
        IF (@len > 4000)
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, 2000)

            -- Let's see if we need four chunks
            IF (@len > 6000)
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, 2000)
                SELECT @Chunk4 = SUBSTRING(@SQL, 6001, (@len - 6001))
            END
              ELSE
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, (@len - 4001))
            END
        END
          ELSE
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, (@len - 2001))
        END
    END

    -- Alright, now that we've broken it down, let's execute it
    EXEC (@Chunk1 + @Chunk2 + @Chunk3 + @Chunk4)
END

Get a backup copy of the .metadata/.plugin/org.eclipse.core.resources folder, then delete that folder and launch eclipse. That should launch the workspace, but all projects will be gone as org.eclipse.core.resources keeps a list of all projects.

Next, close eclipse properly and copy back org.eclipse.core.resources from back up to .metadata/.plugins/ folder overriding the existing one.

Open eclipse and things should work fine with all your projects back to normal.

code below allows user to input items until they press enter key to stop:

In [1]: items=[]
   ...: i=0
   ...: while 1:
   ...:     i+=1
   ...:     item=input('Enter item %d: '%i)
   ...:     if item=='':
   ...:         break
   ...:     items.append(item)
   ...: print(items)
   ...: 

Enter item 1: apple

Enter item 2: pear

Enter item 3: #press enter here
['apple', 'pear']

In [2]: 

The parent function needs the virtual keyword, and the child function needs the override keyword in front of the function definition.

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

I ran into this problem also when including jQuery in my page header, not realizing the host was already including it in the page automatically. So load your page live and check the source to see if jQuery is being linked in.

The verbose configuration option might allow you to see what you want. There is an example in the documentation.

NOTE: Read the comments below: The verbose config options doesn't seem to be available anymore.

Sometimes changing the header is not enough, some sites check the referer as well:

curl -v \
     -H 'Host: restapi.some-site.com' \
     -H 'Connection: keep-alive' \
     -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
     -H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' \
     -e localhost \
     -A 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.65 Safari/537.36' \
     'http://restapi.some-site.com/getsomething?argument=value&argument2=value'

In this example the referer (-e or --referer in curl) is 'localhost'.

You can also try running Bash scripts on Windows using BashWin at https://github.com/skanga/BashWin.

Use the following:

svn rm --keep-local <folder name> to remove the folder and everything within it.

svn rm --keep-local <folder name>/* to keep the folder, but remove everything within the folder.

Here is an example of what happens:

~/code/web/sites/testapp $ svn rm --keep-local includes/data/*
D         includes/data/json
D         includes/data/json/index.html
D         includes/data/json/oembed
D         includes/data/json/oembed/1.0
D         includes/data/json/oembed/1.0/embed1.json
D         includes/data/json/oembed/1.0/embed2.json
D         includes/data/json/oembed/1.0/embed3.json

If you're up for it, use the DateTime class

There are two solutions posted on that page. The one with lower votes I would recommend if possible.

If you are using HTML5 then it is perfectly valid to put a div inside of a. As long as the div doesn't also contain some other specific elements like other link tags.

<a href="Music.html">
  <div id="music" class="nav">
    Music I Like
  </div>
</a>

The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index at all from that example.

div { position: relative; }
.hyperspan {
    position:absolute;
    width:100%;
    height:100%;
    left:0;
    top:0;
}

<div id="music" class="nav">Music I Like 
    <a href="http://www.google.com"> 
        <span class="hyperspan"></span>
    </a>   
</div>

http://jsfiddle.net/rBKXM/9

When you give absolute positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative to the parent div you tell the span to only be as big as that.

For the primitive types, the 'final static' will be a proper declaration to declare a constant. A non-static final variable makes sense when it is a constant reference to an object. In this case each instance can contain its own reference, as shown in JLS 4.5.4.

See Pavel's response for the correct answer.

"mm" means the "minutes" fragment of a date. For the "months" part, use "MM".

So, try to change the code to:

DateFormat df = new SimpleDateFormat("MM/dd/yyyy"); 
Date startDate = df.parse(startDateString);

Edit: A DateFormat object contains a date formatting definition, not a Date object, which contains only the date without concerning about formatting. When talking about formatting, we are talking about create a String representation of a Date in a specific format. See this example:

    import java.text.DateFormat;
    import java.text.SimpleDateFormat;
    import java.util.Date;

    public class DateTest {

        public static void main(String[] args) throws Exception {
            String startDateString = "06/27/2007";

            // This object can interpret strings representing dates in the format MM/dd/yyyy
            DateFormat df = new SimpleDateFormat("MM/dd/yyyy"); 

            // Convert from String to Date
            Date startDate = df.parse(startDateString);

            // Print the date, with the default formatting. 
            // Here, the important thing to note is that the parts of the date 
            // were correctly interpreted, such as day, month, year etc.
            System.out.println("Date, with the default formatting: " + startDate);

            // Once converted to a Date object, you can convert 
            // back to a String using any desired format.
            String startDateString1 = df.format(startDate);
            System.out.println("Date in format MM/dd/yyyy: " + startDateString1);

            // Converting to String again, using an alternative format
            DateFormat df2 = new SimpleDateFormat("dd/MM/yyyy"); 
            String startDateString2 = df2.format(startDate);
            System.out.println("Date in format dd/MM/yyyy: " + startDateString2);
        }
    }

Output:

Date, with the default formatting: Wed Jun 27 00:00:00 BRT 2007
Date in format MM/dd/yyyy: 06/27/2007
Date in format dd/MM/yyyy: 27/06/2007

You should add the httpRuntime block and deal with executionTimeout (in seconds).

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
...
 <system.web>
   <httpRuntime executionTimeout="90" maxRequestLength="4096"
    useFullyQualifiedRedirectUrl="false"
    minFreeThreads="8"
    minLocalRequestFreeThreads="4"
    appRequestQueueLimit="100" />
 </system.web>
... 
</configuration>

For more information, please, see msdn page.

You're correct, in that example the throws is superfluous. It's possible that it was left there from some previous implementation - perhaps the exception was originally thrown instead of caught in the catch block.

I had the same problem and the issue was that my child component had an @input named formControl.

So I just needed to change from:

<my-component [formControl]="formControl"><my-component/>

to:

<my-component [control]="control"><my-component/>

ts:

@Input()
control:FormControl;

If you are using lodash, its even simpler with takeRight.

_.takeRight(arr, 5);

Use this to get the page scroll position.

var screenTop = $(document).scrollTop();

$('#content').css('top', screenTop);

You could also create an ssh tunnel.

docker-compose.yml:

---

version: '2'

services:
  kibana:
    image: "kibana:4.5.1"
    links:
      - elasticsearch
    volumes:
      - ./config/kibana:/opt/kibana/config:ro

  elasticsearch:
    build:
      context: .
      dockerfile: ./docker/Dockerfile.tunnel
    entrypoint: ssh
    command: "-N elasticsearch -L 0.0.0.0:9200:localhost:9200"

docker/Dockerfile.tunnel:

FROM buildpack-deps:jessie

RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive \
    apt-get -y install ssh && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*

COPY ./config/ssh/id_rsa /root/.ssh/id_rsa
COPY ./config/ssh/config /root/.ssh/config
COPY ./config/ssh/known_hosts /root/.ssh/known_hosts
RUN chmod 600 /root/.ssh/id_rsa && \
    chmod 600 /root/.ssh/config && \
    chown $USER:$USER -R /root/.ssh

config/ssh/config:

# Elasticsearch Server
Host elasticsearch
    HostName jump.host.czerasz.com
    User czerasz
    ForwardAgent yes
    IdentityFile ~/.ssh/id_rsa

This way the elasticsearch has a tunnel to the server with the running service (Elasticsearch, MongoDB, PostgreSQL) and exposes port 9200 with that service.

protected void TableGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowIndex == -1 && e.Row.RowType == DataControlRowType.Header)
   {
      GridViewRow gvRow = new GridViewRow(0, 0, DataControlRowType.DataRow,DataControlRowState.Insert);
      for (int i = 0; i < e.Row.Cells.Count; i++)
      {
         TableCell tCell = new TableCell();
         tCell.Text = "&nbsp;";
         gvRow.Cells.Add(tCell);
         Table tbl = e.Row.Parent as Table;
         tbl.Rows.Add(gvRow);
      }
   }
}

In python 3s print function:

lst = [1, 2, 3]
print('My list:', *lst, sep='\n- ')

Output:

My list:
- 1
- 2
- 3

Con: The sep must be a string, so you can't modify it based on which element you're printing. And you need a kind of header to do this (above it was 'My list:').

Pro: You don't have to join() a list into a string object, which might be advantageous for larger lists. And the whole thing is quite concise and readable.

You need to keep an array of the google.maps.Marker objects to hide (or remove or run other operations on them).

In the global scope:

var gmarkers = [];

Then push the markers on that array as you create them:

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude),
    title: locations[i].title,
    icon: icon,
    map:map
});

// Push your newly created marker into the array:
gmarkers.push(marker);

Then to remove them:

function removeMarkers(){
    for(i=0; i<gmarkers.length; i++){
        gmarkers[i].setMap(null);
    }
}

working example (toggles the markers)

How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,

window.onload = doStuff;

function doStuff() {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
}

The other alternative is to keep your <script...</script> just before the closing </body> tag.

You may dynamically load the js inside the page not another js file

you have to use the getScript to load the js file

$.getScript("ajax/test.js", function(data, textStatus, jqxhr) {
console.log(data); //data returned
console.log(textStatus); //success
console.log(jqxhr.status); //200
console.log('Load was performed.');
});

This will give you names and table count of all the databases in you mysql

SELECT TABLE_SCHEMA,COUNT(*) FROM information_schema.tables group by TABLE_SCHEMA;

Please try with the code below

var windowWidth = $(window).width();

$(window).resize(function() {
    if(windowWidth != $(window).width()){
    location.reload();

    return;
    }
});

There are three main reasons for using the assert() function over the normal if else and printf

1. assert() function is mainly used in the debugging phase, it is tedious to write if else with a printf statement everytime you want to test a condition which might not even make its way in the final code.

2. In large software deployments , assert comes very handy where you can make the compiler ignore the assert statements using the NDEBUG macro defined before linking the header file for assert() function.

3. assert() comes handy when you are designing a function or some code and want to get an idea as to what limits the code will and not work and finally include an if else for evaluating it basically playing with assumptions.

Since # has a meaning in Bash, I got to the following solution.

In addition I like better to pack strings with "" to overcome spaces, etc.

A="#sdfs"
if [[ "$A" == "#"* ]];then
    echo "Skip comment line"
fi

if you don't want or need a typed object try:

using Newtonsoft.Json;
// ...   
dynamic json  = JsonConvert.DeserializeObject(str);

or try for a typed object try:

Foo json  = JsonConvert.DeserializeObject<Foo>(str)

This isn't an answer to the tagline question, but it is an answer to the problems mentioned in the body of the question. Instead of using @Before or @After, look into using @org.junit.Rule because it gives you more flexibility. ExternalResource (as of 4.7) is the rule you will be most interested in if you are managing connections. Also, If you want guaranteed execution order of your rules use a RuleChain (as of 4.10). I believe all of these were available when this question was asked. Code example below is copied from ExternalResource's javadocs.

 public static class UsesExternalResource {
  Server myServer= new Server();

  @Rule
  public ExternalResource resource= new ExternalResource() {
      @Override
      protected void before() throws Throwable {
          myServer.connect();
         };

      @Override
      protected void after() {
          myServer.disconnect();
         };
     };

  @Test
  public void testFoo() {
      new Client().run(myServer);
     }
 }

This should help with it. You can then assign your label to this custom class within the storyboard and use it's parameters directly within the properties:

open class SpacingLabel : UILabel {

    @IBInspectable open var lineHeight:CGFloat = 1 {
        didSet {
            let paragraphStyle = NSMutableParagraphStyle()
            paragraphStyle.lineSpacing = 1.0
            paragraphStyle.lineHeightMultiple = self.lineHeight
            paragraphStyle.alignment = self.textAlignment

            let attrString = NSMutableAttributedString(string: self.text!)
            attrString.addAttribute(NSAttributedStringKey.font, value: self.font, range: NSMakeRange(0, attrString.length))
            attrString.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attrString.length))
            self.attributedText = attrString
        }
    } 
}

both -first and -skip are optional parameters, and -context, or -last may be useful in similar situations.

The steps you took are not appropriate because the cell you want formatted is not the trigger cell (presumably won't normally be blank). In your case you want formatting to apply to one set of cells according to the status of various other cells. I suggest with data layout as shown in the image (and with thanks to @xQbert for a start on a suitable formula) you select ColumnA and:

HOME > Styles - Conditional Formatting, New Rule..., Use a formula to determine which cells to format and Format values where this formula is true::

=AND(LEN(E1)*LEN(F1)*LEN(G1)*LEN(H1)=0,NOT(ISBLANK(A1)))

Format..., select formatting, OK, OK.

where I have filled yellow the cells that are triggering the red fill result.

If you have too many installers to find what you are looking for easily, here is some powershell to provide a filter and narrow it down a little by display name.

$filter = "*core*sdk*"; (Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall).Name | % { $path = "Registry::$_"; Get-ItemProperty $path } | Where-Object { $_.DisplayName -like $filter } | Select-Object -Property DisplayName, PsChildName

window.location.href = "/somewhere/else";

./configure --disable-multilib

works for it

Ultimate approach so far, with smallest code:

(IE9+, FF, Webkit)

Using MutationObserver and falling back to the deprecated Mutation events if needed:
(Example below if only for DOM changes concerning nodes appended or removed)

var observeDOM = (function(){
  var MutationObserver = window.MutationObserver || window.WebKitMutationObserver;

  return function( obj, callback ){
    if( !obj || obj.nodeType !== 1 ) return; 

    if( MutationObserver ){
      // define a new observer
      var mutationObserver = new MutationObserver(callback)

      // have the observer observe foo for changes in children
      mutationObserver.observe( obj, { childList:true, subtree:true })
      return mutationObserver
    }
    
    // browser support fallback
    else if( window.addEventListener ){
      obj.addEventListener('DOMNodeInserted', callback, false)
      obj.addEventListener('DOMNodeRemoved', callback, false)
    }
  }
})()

At least in VIM you can select the first column of text you want to insert using Block Visual mode (CTRL+V in non-windows VIMs) and then prepend a # before each line using this sequence:

I#<esc>

In Block Visual mode I moves to insert mode with the cursor before the block on its first line. The inserted text is copied before each line in the block.

Try this

You_command 1>output.log  2>&1

Your usage of &>x.file does work in bash4. sorry for that : (

Here comes some additional tips.

0, 1, 2...9 are file descriptors in bash.

0 stands for stdin, 1 stands for stdout, 2 stands for stderror. 3~9 is spare for any other temporary usage.

Any file descriptor can be redirected to other file descriptor or file by using operator > or >>(append).

Usage: <file_descriptor> > <filename | &file_descriptor>

Please reference to http://www.tldp.org/LDP/abs/html/io-redirection.html

Ran into the issue, but it was only two directories and unknown to me was that both those directories ended up being configured as git submodules. How that happened I have no clue, but the process was to follow some of the instructions on this link, but NOT remove the directory (as he does at the end) but rather do git add path/to/dir

You can use one of these solutions:

HTML

<a>link</a>

JavaScript

<a href="javascript:function() { return false; }">link</a>
<a href="/" onclick="return false;">link</a>

CSS

<a href="www.page.com" disabled="disabled">link</a>

<style type="text/css">
    a[disabled="disabled"] {
        pointer-events: none;
    }
</style>

This is a long post, but I was tired of all these examples that weren't working for me because they used Promise objects or an errant this that has a different meaning when you are using Reactjs. My implementation was using a DropZone with reactjs, and I got the bytes using a framework similar to what is posted at this following site, when nothing else above would work: https://www.mokuji.me/article/drop-upload-tutorial-1 . There were 2 keys, for me:

1. You have to get the bytes from the event object, using and during a FileReader's onload function.

2. I tried various combinations, but in the end, what worked was:

   const bytes = e.target.result.split('base64,')[1];

Where e is the event. React requires const, you could use var in plain Javascript. But that gave me the base64 encoded byte string.

So I'm just going to include the applicable lines for integrating this as if you were using React, because that's how I was building it, but try to also generalize this, and add comments where necessary, to make it applicable to a vanilla Javascript implementation - caveated that I did not use it like that in such a construct to test it.

These would be your bindings at the top, in your constructor, in a React framework (not relevant to a vanilla Javascript implementation):

this.uploadFile = this.uploadFile.bind(this);
this.processFile = this.processFile.bind(this);
this.errorHandler = this.errorHandler.bind(this);
this.progressHandler = this.progressHandler.bind(this);

And you'd have onDrop={this.uploadFile} in your DropZone element. If you were doing this without React, this is the equivalent of adding the onclick event handler you want to run when you click the "Upload File" button.

<button onclick="uploadFile(event);" value="Upload File" />

Then the function (applicable lines... I'll leave out my resetting my upload progress indicator, etc.):

uploadFile(event){
    // This is for React, only
    this.setState({
      files: event,
    });
    console.log('File count: ' + this.state.files.length);

    // You might check that the "event" has a file & assign it like this 
    // in vanilla Javascript:
    // var files = event.target.files;
    // if (!files && files.length > 0)
    //     files = (event.dataTransfer ? event.dataTransfer.files : 
    //            event.originalEvent.dataTransfer.files);

    // You cannot use "files" as a variable in React, however:
    const in_files = this.state.files;

    // iterate, if files length > 0
    if (in_files.length > 0) {
      for (let i = 0; i < in_files.length; i++) {
      // use this, instead, for vanilla JS:
      // for (var i = 0; i < files.length; i++) {
        const a = i + 1;
        console.log('in loop, pass: ' + a);
        const f = in_files[i];  // or just files[i] in vanilla JS

        const reader = new FileReader();
        reader.onerror = this.errorHandler;
        reader.onprogress = this.progressHandler;
        reader.onload = this.processFile(f);
        reader.readAsDataURL(f);
      }      
   }
}

There was this question on that syntax, for vanilla JS, on how to get that file object:

JavaScript/HTML5/jQuery Drag-And-Drop Upload - "Uncaught TypeError: Cannot read property 'files' of undefined"

Note that React's DropZone will already put the File object into this.state.files for you, as long as you add files: [], to your this.state = { .... } in your constructor. I added syntax from an answer on that post on how to get your File object. It should work, or there are other posts there that can help. But all that Q/A told me was how to get the File object, not the blob data, itself. And even if I did fileData = new Blob([files[0]]); like in sebu's answer, which didn't include var with it for some reason, it didn't tell me how to read that blob's contents, and how to do it without a Promise object. So that's where the FileReader came in, though I actually tried and found I couldn't use their readAsArrayBuffer to any avail.

You will have to have the other functions that go along with this construct - one to handle onerror, one for onprogress (both shown farther below), and then the main one, onload, that actually does the work once a method on reader is invoked in that last line. Basically you are passing your event.dataTransfer.files[0] straight into that onload function, from what I can tell.

So the onload method calls my processFile() function (applicable lines, only):

processFile(theFile) {
  return function(e) {
    const bytes = e.target.result.split('base64,')[1];
  }
}

And bytes should have the base64 bytes.

Additional functions:

errorHandler(e){
    switch (e.target.error.code) {
      case e.target.error.NOT_FOUND_ERR:
        alert('File not found.');
        break;
      case e.target.error.NOT_READABLE_ERR:
        alert('File is not readable.');
        break;
      case e.target.error.ABORT_ERR:
        break;    // no operation
      default:
        alert('An error occurred reading this file.');
        break;
    }
  }

progressHandler(e) {
    if (e.lengthComputable){
      const loaded = Math.round((e.loaded / e.total) * 100);
      let zeros = '';

      // Percent loaded in string
      if (loaded >= 0 && loaded < 10) {
        zeros = '00';
      }
      else if (loaded < 100) {
        zeros = '0';
      }

      // Display progress in 3-digits and increase bar length
      document.getElementById("progress").textContent = zeros + loaded.toString();
      document.getElementById("progressBar").style.width = loaded + '%';
    }
  }

And applicable progress indicator markup:

<table id="tblProgress">
  <tbody>
    <tr>
      <td><b><span id="progress">000</span>%</b> <span className="progressBar"><span id="progressBar" /></span></td>
    </tr>                    
  </tbody>
</table>

And CSS:

.progressBar {
  background-color: rgba(255, 255, 255, .1);
  width: 100%;
  height: 26px;
}
#progressBar {
  background-color: rgba(87, 184, 208, .5);
  content: '';
  width: 0;
  height: 26px;
}

EPILOGUE:

Inside processFile(), for some reason, I couldn't add bytes to a variable I carved out in this.state. So, instead, I set it directly to the variable, attachments, that was in my JSON object, RequestForm - the same object as my this.state was using. attachments is an array so I could push multiple files. It went like this:

  const fileArray = [];
  // Collect any existing attachments
  if (RequestForm.state.attachments.length > 0) {
    for (let i=0; i < RequestForm.state.attachments.length; i++) {
      fileArray.push(RequestForm.state.attachments[i]);
    }
  }
  // Add the new one to this.state
  fileArray.push(bytes);
  // Update the state
  RequestForm.setState({
    attachments: fileArray,
  });

Then, because this.state already contained RequestForm:

this.stores = [
  RequestForm,    
]

I could reference it as this.state.attachments from there on out. React feature that isn't applicable in vanilla JS. You could build a similar construct in plain JavaScript with a global variable, and push, accordingly, however, much easier:

var fileArray = new Array();  // place at the top, before any functions

// Within your processFile():
var newFileArray = [];
if (fileArray.length > 0) {
  for (var i=0; i < fileArray.length; i++) {
    newFileArray.push(fileArray[i]);
  }
}
// Add the new one
newFileArray.push(bytes);
// Now update the global variable
fileArray = newFileArray;

Then you always just reference fileArray, enumerate it for any file byte strings, e.g. var myBytes = fileArray[0]; for the first file.

I was facing the same issue in which I need to align selected placeholder value to the right of the select box & also need to align options to right but when I have used direction: rtl; to select & applied some right padding to select then all options also getting shift to the right by padding as I only want to apply padding to selected placeholder.

I have fixed the issue by the following the style:

select:first-child{
  text-indent: 24%;
  direction: rtl;
  padding-right: 7px;
}

select option{
  direction: rtl;
}

You can change text-indent as per your requirement. Hope it will help you.

The universal tool for string formatting, sprintf:

$stamp = sprintf('%s%02s', $year, $month);

http://php.net/manual/en/function.sprintf.php

A trap is called by code like programs and used e. g. to call OS routines (i. e. normally synchronous). An interrupt is called by events (many times hardware, like the network card having received data, or the CPU timer), and - as the name suggests - interrupts the normal control flow, as the CPU has to switch to the driver routine to handle the event.

You must install the JDT/Eclipse Java 8 Support For Kepler. https://wiki.eclipse.org/JDT/Eclipse_Java_8_Support_For_Kepler

You can read files in raw/res using getResources().openRawResource(R.raw.myfilename).

BUT there is an IDE limitation that the file name you use can only contain lower case alphanumeric characters and dot. So file names like XYZ.txt or my_data.bin will not be listed in R.

Hey we can also use this regex solution.

String chomp = StringUtils.normalizeSpace(sentence.replaceAll("[\\r\\n]"," "));

See if this helps:

[Serializable()]
[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
    [XmlArrayItem(typeof(Car))]
    public Car[] Car { get; set; }
}

.

[Serializable()]
public class Car
{
    [System.Xml.Serialization.XmlElement()]
    public string StockNumber{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Make{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Model{ get; set; }
}

And failing that use the xsd.exe program that comes with visual studio to create a schema document based on that xml file, and then use it again to create a class based on the schema document.

Let's assume you want to overwrite the same file:

import json

with open('data.json', 'r') as data_file:
    data = json.load(data_file)

for element in data:
    element.pop('hours', None)

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

dict.pop(<key>, not_found=None) is probably what you where looking for, if I understood your requirements. Because it will remove the hours key if present and will not fail if not present.

However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?

Now, if you really want to use del instead of pop, here is how you could make your code work:

import json

with open('data.json') as data_file:
    data = json.load(data_file)

for element in data:
    if 'hours' in element:
        del element['hours']

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.

I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.

with is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.

Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.

I hope it's clear enough...

SECOND EDIT

This time, it seems clear that you need to do this:

with open('dest_file.json', 'w') as dest_file:
    with open('source_file.json', 'r') as source_file:
        for line in source_file:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            dest_file.write(json.dumps(element))

Use this function:

$(".price").each(function(){
total_price += parseInt($(this).val());
});

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

If you want to shut down computer remotely then you can use

Using System.Diagnostics;

on any button click

{
    Process.Start("Shutdown","-i");
}

The immediate cause of the problem is that the JDBC driver has attempted to read from a network Socket that has been closed by "the other end".

This could be due to a few things:

• If the remote server has been configured (e.g. in the "SQLNET.ora" file) to not accept connections from your IP.

• If the JDBC url is incorrect, you could be attempting to connect to something that isn't a database.

• If there are too many open connections to the database service, it could refuse new connections.

Given the symptoms, I think the "too many connections" scenario is the most likely. That suggests that your application is leaking connections; i.e. creating connections and then failing to (always) close them.

Update all your code that calls load function like,

$(window).load(function() { ... });

To

$(window).on('load', function() { ... });

jquery.js:9612 Uncaught TypeError: url.indexOf is not a function

This error message comes from jQuery.fn.load function.

I've come across the same issue on my application. After some digging, I found this statement in jQuery blog,

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

I simply just change how my jQuery objects call the load function like above. And everything works as expected.

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.

Here is an example of data binding with AngularJS, using an input field. I will explain later

HTML Code

<div ng-app="myApp" ng-controller="myCtrl" class="formInput">
     <input type="text" ng-model="watchInput" Placeholder="type something"/>
     <p>{{watchInput}}</p> 
</div>

AngularJS Code

myApp = angular.module ("myApp", []);
myApp.controller("myCtrl", ["$scope", function($scope){
  //Your Controller code goes here
}]);

As you can see in the example above, AngularJS uses ng-model to listen and watch what happens on HTML elements, especially on input fields. When something happens, do something. In our case, ng-model is bind to our view, using the mustache notation {{}}. Whatever is typed inside the input field is displayed on the screen instantly. And that's the beauty of data binding, using AngularJS in its simplest form.

Hope this helps.

See a working example here on Codepen

If you are running windows 7 (professional) and Git for Windows (v 2.15 or above), you can simply run below command to find out what are different diff tools supported by your Git for Windows

git difftool --tool-help

You will see output similar to this

git difftool --tool=' may be set to one of the following:
vimdiff vimdiff2 vimdiff3

it means that your git does not support(can not find) beyond compare as difftool right now.

In order for Git to find beyond compare as valid difftool, you should have Beyond Compare installation directory in your system path environment variable. You can check this by running bcompare from shell(cmd, git bash or powershell. I am using Git Bash). If Beyond Compare does not launch, add its installation directory (in my case, C:\Program Files\Beyond Compare 4) to your system path variable. After this, restart your shell. Git will show Beyond Compare as possible difftool option. You can use any of below commands to launch beyond compare as difftool (for example, to compare any local file with some other branch)

git difftool -t bc branchnametocomparewith -- path-to-file
or 
git difftool --tool=bc branchnametocomparewith -- path-to-file

You can configure beyond compare as default difftool using below commands

   git config --global diff.tool bc

p.s. keep in mind that bc in above command can be bc3 or bc based upon what Git was able to find from your path system variable.

PostgreSQL gives you 2 ways of doing this:

SELECT DISTINCT * FROM (VALUES('a'),('b'),('a'),('v')) AS tbl(col1)

or

SELECT DISTINCT * FROM (select unnest(array['a','b', 'a','v'])) AS tbl(col1)

using array approach you can also do something like this:

SELECT DISTINCT * FROM (select unnest(string_to_array('a;b;c;d;e;f;a;b;d', ';'))) AS tbl(col1)

I suspect the error is caused by this:

foreach (KeyValuePair<int, int> kvp in rankings)

rankings is a dictionary, which is IEnumerable. By using it in a foreach loop, you're specifying that you want each KeyValuePair from the dictionary in a deferred manner. That is, the next KeyValuePair is not returned until your loop iterates again.

But you're modifying the dictionary inside your loop:

rankings[kvp.Key] = rankings[kvp.Key] + 4;

which isn't allowed...so you get the exception.

You could simply do this

foreach (KeyValuePair<int, int> kvp in rankings.ToArray())

Shortest

[...rates.children].find(c=>c.checked).value

let v= [...rates.children].find(c=>c.checked).value

console.log(v);

<div id="rates">
  <input type="radio" id="r1" name="rate" value="Fixed Rate"> Fixed Rate
  <input type="radio" id="r2" name="rate" value="Variable Rate"> Variable Rate
  <input type="radio" id="r3" name="rate" value="Multi Rate" checked="checked"> Multi Rate  
</div>

If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b is a power of two, a % b == a & (b - 1).

For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63, because 63 is 111111 in binary.

The masked, higher digits are not of interest to us. Try it out!

Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

I use simple grep inside function in bash script to receive properties from .properties file.

This properties file I use in two places - to setup dev environment and as application parameters.

I believe that grep may work slow in big loops but it solves my needs when I want to prepare dev environment.

Hope, someone will find this useful.

Example:

File: setup.sh

#!/bin/bash

ENV=${1:-dev}

function prop {
    grep "${1}" env/${ENV}.properties|cut -d'=' -f2

If you remind yourself standard school method of division and do it in binary, you will discover that in case of 3 you only divide and subtract a limited set of values (from 0 to 5 in this case). These can be treated with a switch statement to get rid of arithmetic operators.

static unsigned lamediv3(unsigned n)
{
  unsigned result = 0, remainder = 0, mask = 0x80000000;

  // Go through all bits of n from MSB to LSB.
  for (int i = 0; i < 32; i++, mask >>= 1)
  {
    result <<= 1;
    // Shift in the next bit of n into remainder.
    remainder = remainder << 1 | !!(n & mask);

    // Divide remainder by 3, update result and remainer.
    // If remainder is less than 3, it remains intact.
    switch (remainder)
    {
    case 3:
      result |= 1;
      remainder = 0;
      break;

    case 4:
      result |= 1;
      remainder = 1;
      break;

    case 5:
      result |= 1;
      remainder = 2;
      break;
    }
  }

  return result;
}

#include <cstdio>

int main()
{
  // Verify for all possible values of a 32-bit unsigned integer.
  unsigned i = 0;

  do
  {
    unsigned d = lamediv3(i);

    if (i / 3 != d)
    {
      printf("failed for %u: %u != %u\n", i, d, i / 3);
      return 1;
    }
  }
  while (++i != 0);
}

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

The most complete answer I have found is here: http://blog.kikicode.com/2013/10/installing-android-adb-driver-in.html

I'm copying the complete answer below.

Installing Android ADB driver in Windows 8.1 64-bit when all else fails

For some reason I just couldn't get my machine to recognize Xperia J in Windows 8.1 64-bit. Even after installing latest Sony PC Companion (2.10.174). Device Manager kept showing yellow exclamation mark to an 'Android'.

Here's the solution, but I don't promise it will work on your device!

1. Find out your device's VID and PID

Open Device Manager, right-click that Android with yellow exclamation mark and click Properties. Go to Details tab. In Property, select Hardware Ids. Right-click the value and click Copy. Paste the value somewhere.

2. Download Android USB Driver

Run Android SDK Manager. Expand Extras, tick Google USB Driver, click Install packages. After installation, look for the driver location by hovering mouse over Google USB Driver. The location will appear in the tooltip.

3. Modify android_winusb.inf

Go to the usb driver location, for example in the above picture it is c:\Android\android-studio\sdk\extras\google\usb_driver Make a backup copy of android_winusb.inf Open android_winusb.inf with a text editor. Notepad is fine but Notepad++ is better, it will syntax highlight the inf file! Look for [Google.NTx86], and insert a line with your device's hardware ID that you copied above, for example

[Google.NTx86]

; ... other existing lines

;SONY Sony Xperia J
%CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_6188&MI_01

Look for [Google.NTamd86], and insert the same lines, for example:

[Google.NTamd64]

; ... other existing lines

;SONY Sony Xperia J
%CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_6188&MI_01

Save the file.

4. Disable driver signing

Run Command Prompt as an administrator Paste and run the following commands:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

Restart Windows.

5. Install driver

Open Device Manager, right-click that Android with yellow exclamation mark and click Update Driver Software. Click Browse my computer for driver software. Enter or browse to the folder containing android_winusb.inf, eg: C:\Android\android-studio\sdk\extras\google\usb_driver Click Next. The driver will install. Run adb devices to confirm your device is working fine.

6. Re-enable driver signing

Run Command Prompt as an administrator Paste and run the following commands:

bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING OFF

Restart Windows. Run adb devices to reconfirm!

window.open doesn't work across all browsers, Google it and you will find a way of detecting the correct dialog type.

Also, move the onclick call to the input button for it to only fire when the user submits.

Places is a list and not a dictionary. This line below should therefore not work:

print data['places']['latitude']

You need to select one of the items in places and then you can list the place's properties. So to get the first post code you'd do:

print data['places'][0]['post code']

You use input.files property. It's a collection of File objects and each file has a name property:

onmouseout="for (var i = 0; i < this.files.length; i++) alert(this.files[i].name);"

lace to store your loaded class definition and metadata. If a large code-base project is loaded, the insufficient Perm Gen size will cause the popular Java.Lang.OutOfMemoryError: PermGen.

C:\xampp\mysql\bin\mysql -u root -p testdatabase < C:\Users\Juan\Desktop\databasebackup.sql

That worked for me to import 400MB file into my database.

Modern style is to define IPet and PetBase.

The advantage of the interface is that other code can use it without any ties whatsoever to other executable code. Completely "clean." Also interfaces can be mixed.

But base classes are useful for simple implementations and common utilities. So provide an abstract base class as well to save time and code.

$(document).ready(function() {
    $('#abc_frame').attr('src',url);
})

a=10

isinstance(a,int)  #True

b='abc'

isinstance(b,int)  #False

You should use sum:

Total = df['MyColumn'].sum()
print (Total)
319

Then you use loc with Series, in that case the index should be set as the same as the specific column you need to sum:

df.loc['Total'] = pd.Series(df['MyColumn'].sum(), index = ['MyColumn'])
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

because if you pass scalar, the values of all rows will be filled:

df.loc['Total'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A        84   13.0   69.0
1        B        76   77.0  127.0
2        C        28   69.0   16.0
3        D        28   28.0   31.0
4        E        19   20.0   85.0
5        F        84  193.0   70.0
Total  319       319  319.0  319.0

Two other solutions are with at, and ix see the applications below:

df.at['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

df.ix['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

Note: Since Pandas v0.20, ix has been deprecated. Use loc or iloc instead.

You could use NOT IN:

SELECT A.* FROM A WHERE ID NOT IN(SELECT ID FROM B)

However, meanwhile i prefer NOT EXISTS:

SELECT A.* FROM A WHERE NOT EXISTS(SELECT 1 FROM B WHERE B.ID=A.ID)

There are other options as well, this article explains all advantages and disadvantages very well:

Should I use NOT IN, OUTER APPLY, LEFT OUTER JOIN, EXCEPT, or NOT EXISTS?

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

We usually declare the constant as static. The reason for that is because Java creates copies of non static variables every time you instantiate an object of the class.

So if we make the constants static it would not do so and would save memory.

With final we can make the variable constant.

Hence the best practice to define a constant variable is the following:

private static final String YOUR_CONSTANT = "Some Value"; 

The access modifier can be private/public depending on the business logic.

Here Check below code snippet which, In this, I miss-spelled the image name. So, just because of that it is showing the alternative image as not found image ( 404.svg ).

This seems to be a bug in the newly added support for nested fragments. Basically, the child FragmentManager ends up with a broken internal state when it is detached from the activity. A short-term workaround that fixed it for me is to add the following to onDetach() of every Fragment which you call getChildFragmentManager() on:

@Override
public void onDetach() {
    super.onDetach();

    try {
        Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this, null);

    } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}

Since the API you're calling is async, the Parallel.ForEach version doesn't make much sense. You shouldnt use .Wait in the WaitAll version since that would lose the parallelism Another alternative if the caller is async is using Task.WhenAll after doing Select and ToArray to generate the array of tasks. A second alternative is using Rx 2.0

You can use Object.assign() to merge them into a new object:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_

const item = {_x000D_

You can also use object spread, which is a Stage 4 proposal for ECMAScript:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = { ...item, location: response }; // or { ...response } if you want to clone response as well_x000D_
_x000D_
console.log(newItem );

Yes, do

NSString *str = [NSString stringWithFormat: @"first part %@ second part", varyingString];

For concatenation you can use stringByAppendingString

NSString *str = @"hello ";
str = [str stringByAppendingString:@"world"]; //str is now "hello world"

For multiple strings

NSString *varyingString1 = @"hello";
NSString *varyingString2 = @"world";
NSString *str = [NSString stringWithFormat: @"%@ %@", varyingString1, varyingString2];
//str is now "hello world"

If for a block cipher you're not going to use a Cipher transformation that includes a padding scheme, you need to have the number of bytes in the plaintext be an integral multiple of the block size of the cipher.

So either pad out your plaintext to a multiple of 16 bytes (which is the AES block size), or specify a padding scheme when you create your Cipher objects. For example, you could use:

Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

Unless you have a good reason not to, use a padding scheme that's already part of the JCE implementation. They've thought out a number of subtleties and corner cases you'll have to realize and deal with on your own otherwise.

Ok, your second problem is that you are using String to hold the ciphertext.

In general,

String s = new String(someBytes);
byte[] retrievedBytes = s.getBytes();

will not have someBytes and retrievedBytes being identical.

If you want/have to hold the ciphertext in a String, base64-encode the ciphertext bytes first and construct the String from the base64-encoded bytes. Then when you decrypt you'll getBytes() to get the base64-encoded bytes out of the String, then base64-decode them to get the real ciphertext, then decrypt that.

The reason for this problem is that most (all?) character encodings are not capable of mapping arbitrary bytes to valid characters. So when you create your String from the ciphertext, the String constructor (which applies a character encoding to turn the bytes into characters) essentially has to throw away some of the bytes because it can make no sense of them. Thus, when you get bytes out of the string, they are not the same bytes you put into the string.

In Java (and in modern programming in general), you cannot assume that one character = one byte, unless you know absolutely you're dealing with ASCII. This is why you need to use base64 (or something like it) if you want to build strings from arbitrary bytes.

I needed to copy an object by value (not reference) and I found this page helpful:

What is the most efficient way to deep clone an object in JavaScript?. In particular, cloning an object with the following code by John Resig:

//Shallow copy
var newObject = jQuery.extend({}, oldObject);
// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

You can use include/include_once or require/require_once

require_once('class.php');

Alternatively, use autoloading by adding to page.php

<?php 
function my_autoloader($class) {
    include 'classes/' . $class . '.class.php';
}

spl_autoload_register('my_autoloader');

$vars = new IUarts(); 
print($vars->data);    
?>

It also works adding that __autoload function in a lib that you include on every file like utils.php.

There is also this post that has a nice and different approach.

Efficient PHP auto-loading and naming strategies

I use: /drawable/circulo.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <solid android:angle="270"
        android:color="@color/your_color" />

</shape>

And then I use it in my TextView as:

android:background="@drawable/circulo"

no need to complicated it.

    <bookstore>
     <book location="US">A1</book>
     <category>
      <book location="US">B1</book>
      <book location="FIN">B2</book>
     </category>
     <section>
      <book location="FIN">C1</book>
      <book location="US">C2</book>
     </section>
    </bookstore> 

So Given the above; you can select the first book with

(//book[@location='US'])[1]

And this will find the first one anywhere that has a location US. [A1]

//book[@location='US']

Would return the node set with all books with location US. [A1,B1,C2]

(//category/book[@location='US'])[1]

Would return the first book location US that exists in a category anywhere in the document. [B1]

(/bookstore//book[@location='US'])[1]

will return the first book with location US that exists anywhere under the root element bookstore; making the /bookstore part redundant really. [A1]

In direct answer:

/bookstore/book[@location='US'][1]

Will return you the first node for book element with location US that is under bookstore [A1]

Incidentally if you wanted, in this example to find the first US book that was not a direct child of bookstore:

(/bookstore/*//book[@location='US'])[1]

another solution is to override the join operator of the str class.

Let us define a new class my_string as follows

class my_string(str):
    def join(self, l):
        l_tmp = [str(x) for x in l]
        return super(my_string, self).join(l_tmp)

Then you can do

class Obj:
    def __str__(self):
        return 'name'

list = [Obj(), Obj(), Obj()]
comma = my_string(',')

print comma.join(list)

and you get

name,name,name

BTW, by using list as variable name you are redefining the list class (keyword) ! Preferably use another identifier name.

Hope you'll find my answer useful.

To concatenate two strings in 2008 or prior:

SELECT ISNULL(FirstName, '') + ' ' + ISNULL(SurName, '')

good to use ISNULL because "String + NULL" will give you a NULL only

One more thing: Make sure you are concatenating strings otherwise use a CAST operator:

SELECT 2 + 3 

Will give 5

SELECT '2' + '3'

Will give 23

split with the + sign like this way

String a = tv.getText().toString();
String aa[];
if(a.contains("+"))
    aa = a.split("+");

now convert the array

Integer.parseInt(aa[0]); // and so on

First you have to click on the report, Then View -> Report Data

When you get the width and height of a resized image Get width of a resized image after UIViewContentModeScaleAspectFit, you can resize your imageView:

imageView.frame = CGRectMake(0, 0, resizedWidth, resizedHeight);
imageView.center = imageView.superview.center;

I haven't checked if it works, but I think all should be OK

I have created a demo for you.

Here is how your nested structure should be in Bootstrap 3:

<div class="form-group">
    <label for="birthday" class="col-xs-2 control-label">Birthday</label>
    <div class="col-xs-10">
        <div class="form-inline">
            <div class="form-group">
                <input type="text" class="form-control" placeholder="year"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="month"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="day"/>
            </div>
        </div>
    </div>
</div>

Notice how the whole form-inline is nested within the col-xs-10 div containing the control of the horizontal form. In other terms, the whole form-inline is the "control" of the birthday label in the main horizontal form.

Note that you will encounter a left and right margin problem by nesting the inline form within the horizontal form. To fix this, add this to your css:

.form-inline .form-group{
    margin-left: 0;
    margin-right: 0;
}

Use the queryset object update method:

MyModel.objects.filter(pk=some_value).update(field1='some value')

https://medium.com/the-resonant-web/spring-boot-2-0-project-structure-and-best-practices-part-2-7137bdcba7d3

I think this is a good structure. And it is a nicely written blog explaining the mindset of these choices.

While searching about this problem, I found a recommendation that Page Visibility API should be used. Most modern browsers support this API according to Can I Use: http://caniuse.com/#feat=pagevisibility.

Here's a working example (derived from this snippet):

$(document).ready(function() {
  var hidden, visibilityState, visibilityChange;

  if (typeof document.hidden !== "undefined") {
    hidden = "hidden", visibilityChange = "visibilitychange", visibilityState = "visibilityState";
  } else if (typeof document.msHidden !== "undefined") {
    hidden = "msHidden", visibilityChange = "msvisibilitychange", visibilityState = "msVisibilityState";
  }

  var document_hidden = document[hidden];

  document.addEventListener(visibilityChange, function() {
    if(document_hidden != document[hidden]) {
      if(document[hidden]) {
        // Document hidden
      } else {
        // Document shown
      }

      document_hidden = document[hidden];
    }
  });
});

Update: The example above used to have prefixed properties for Gecko and WebKit browsers, but I removed that implementation because these browsers have been offering Page Visibility API without a prefix for a while now. I kept Microsoft specific prefix in order to stay compatible with IE10.

With that parameters you're triggering the wrong overloaded function/method.

What worked for me:

<%= Html.ActionLink("Details", "Details", "Product", new { id=item.ID }, null) %>

It fires HtmlHelper.ActionLink(string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes)

I'm using MVC 4.

Cheerio!

Using {dplyr}:

library(dplyr)

# percentiles
infert %>% 
  mutate(PCT = ntile(age, 100))

# quartiles
infert %>% 
  mutate(PCT = ntile(age, 4))

# deciles
infert %>% 
  mutate(PCT = ntile(age, 10))

Generally, instances of classes that deal with I/O should be closed after you're finished with them. So at the end of your code you could add in.close().

You can use brew to start/stop pgsql. I've following short cuts in my ~/.bashrc file

alias start-pg='brew services start postgresql'
alias stop-pg='brew services stop postgresql'
alias restart-pg='brew services restart postgresql'

To make things easier asp Question 2 stated, you can make use of lambda method like this to save variable memory and to avoid navigating up and down in your view class

//method 1
findViewById(R.id.buttonSend).setOnClickListener(v -> {
          // handle click
});

but if you wish to apply click event to your button at once in a method.

you can make use of Question 3 by @D. Tran answer. But do not forget to implement your view class with View.OnClickListener.

In other to use Question #3 properly

After coming across this error and not finding anything on the web that set me right, I thought I'd add another reason for getting this Exception - namely that the source and destination paths in the File Copy command are the same. It took me a while to figure it out, but it may help to add code somewhere to throw an exception if source and destination paths are pointing to the same file.

Good luck!

I think you want a pipelined table function.

Something like this:

CREATE OR REPLACE PACKAGE test AS

    TYPE measure_record IS RECORD(
       l4_id VARCHAR2(50), 
       l6_id VARCHAR2(50), 
       l8_id VARCHAR2(50), 
       year NUMBER, 
       period NUMBER,
       VALUE NUMBER);

    TYPE measure_table IS TABLE OF measure_record;

    FUNCTION get_ups(foo NUMBER)
        RETURN measure_table
        PIPELINED;
END;

CREATE OR REPLACE PACKAGE BODY test AS

    FUNCTION get_ups(foo number)
        RETURN measure_table
        PIPELINED IS

        rec            measure_record;

    BEGIN
        SELECT 'foo', 'bar', 'baz', 2010, 5, 13
          INTO rec
          FROM DUAL;

        -- you would usually have a cursor and a loop here   
        PIPE ROW (rec);

        RETURN;
    END get_ups;
END;

For simplicity I removed your parameters and didn't implement a loop in the function, but you can see the principle.

Usage:

SELECT *
  FROM table(test.get_ups(0));



L4_ID L6_ID L8_ID       YEAR     PERIOD      VALUE
----- ----- ----- ---------- ---------- ----------
foo   bar   baz         2010          5         13
1 row selected.

Or using the famous Joda Time library:

DateTime dateTime = new DateTime();
dateTime = dateTime.minusHours(1);
Date modifiedDate = dateTime.toDate();

JSfiddle

function deleteEmpty(obj){
        for(var k in obj)
         if(k == "children"){
             if(obj[k]){
                     deleteEmpty(obj[k]);
             }else{
                   delete obj.children;
              } 
         }
    }

for(var i=0; i< a.children.length; i++){
 deleteEmpty(a.children[i])
}

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
    file = new File
    {  
       Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions
    };

    return file.Id;
}

Figured it out. The VM's in cloud engine don't come with a root password setup by default so you'll first need to change the password using

sudo passwd

If you do everything correctly, it should do something like this:

user@server[~]# sudo passwd
Changing password for user root.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

i had the same problem... every time that i wanted to publish my css.. I had to make a search/replace.. and relative path wouldnt work either for me because the relative paths were different from dev to production.

Finally was tired of doing the search/replace and I created a dynamic css, (e.g. www.mysite.com/css.php) it's the same but now i could use my php constants in the css. somethig like

.icon{
  background-image:url('<?php echo BASE_IMAGE;?>icon.png');
}

and it's not a bad idea to make it dynamic because now i could compress it using YUI compressor without loosing the original format on my dev server.

Good Luck!

Follow @Duncan's @Bartvds's answer, here to provide a workable way after years passed.

At this point after Typescript 1.5 released (@Jun 15 '15), your helpful interface

interface MyType {
    instanceMethod();
}

interface MyTypeStatic {
    new():MyType;
    staticMethod();
}

can be implemented this way with the help of decorator.

/* class decorator */
function staticImplements<T>() {
    return <U extends T>(constructor: U) => {constructor};
}

@staticImplements<MyTypeStatic>()   /* this statement implements both normal interface & static interface */
class MyTypeClass { /* implements MyType { */ /* so this become optional not required */
    public static staticMethod() {}
    instanceMethod() {}
}

Refer to my comment at github issue 13462.

visual result: Compile error with a hint of static method missing.

After static method implemented, hint for method missing.

Compilation passed after both static interface and normal interface fulfilled.

Selenium http://www.seleniumhq.org/ is the best solution for me. you can code it with python, java, or anything programming language you like with ease. and easy simulation that convert into program.

I don't know of a global setting nither but you can try this:

1. Save all Visual Studio templates in UTF-8
2. Write a Visual Studio Macro/Addin that will listen to the DocumentSaved event and will save the file in UTF-8 format (if not already).
3. Put a proxy on your source control that will make sure that new files are always UTF-8.

It's difficult to figure out what you're trying to do with this sample but you're actually on the right track thinking about using classes. I've created a JSFiddle to help demonstrate a slightly better way (I hope) of doing this.

Here's the fiddle: link.

What you do is, instead of working with IDs, you work with classes. In your code sample, there are Oranges and Apples. I treat them as product categories (as I don't really know what your purpose is), with their own ids. So, I mark the product <tr>s with class="cat1" or class="cat2".

I also mark the links with a simple .toggler class. It's not good practice to have onclick attributes on elements themselves. You should 'bind' the events on page load using JavaScript. I do this using jQuery.

$(".toggler").click(function(e){
    // you handle the event here
});

With this format, you are binding an event handler to the click event of links with class toggler. In my code, I add a data-prod-cat attribute to the toggler links to specify which product rows they should control. (The reason for my using a data-* attribute is explained here. You can Google 'html5 data attributes' for more information.)

In the event handler, I do this:

$('.cat'+$(this).attr('data-prod-cat')).toggle();

With this code, I'm actually trying to create a selector like $('.cat1') so I can select rows for a specific product category, and change their visibility. I use $(this).attr('data-prod-cat') this to access the data-prod-cat attribute of the link the user clicks. I use the jQuery toggle function, so that I don't have to write logic like if visible, then hide element, else make it visible like you do in your JS code. jQuery deals with that. The toggle function does what it says and toggles the visibility of the specified element(s).

I hope this was explanatory enough.

Set the position to absolute; to move the caption area in the correct position

CSS

.post-content {
    background: none repeat scroll 0 0 #FFFFFF;
    opacity: 0.5;
    margin: -54px 20px 12px; 
    position: absolute;
}

Bootply

You have to use Promise to print or store values of element.

 var ExpectedValue:string ="AllTestings.com";
          element(by.id("xyz")).getAttribute("value").then(function (Text) {

                        expect(Text.trim()).toEqual("ExpectedValue", "Wrong page navigated");//Assertion
        console.log("Text");//Print here in Console

                    });

The pragmatic regex (<[^>]+) style=".*?" will solve this problem in all reasonable cases. The part of the match that is not the first captured group should be removed, like this:

$output = preg_replace('/(<[^>]+) style=".*?"/i', '$1', $input);

Match a < followed by one or more "not >" until we come to space and the style="..." part. The /i makes it work even with STYLE="...". Replace this match with $1, which is the captured group. It will leave the tag as is, if the tag doesn't include style="...".

As far as I know you can only join this way:

var query = from obj_i in set1
join obj_j in set2 on 
    new { 
      JoinProperty1 = obj_i.SomeField1,
      JoinProperty2 = obj_i.SomeField2,
      JoinProperty3 = obj_i.SomeField3,
      JoinProperty4 = obj_i.SomeField4
    } 
    equals 
    new { 
      JoinProperty1 = obj_j.SomeOtherField1,
      JoinProperty2 = obj_j.SomeOtherField2,
      JoinProperty3 = obj_j.SomeOtherField3,
      JoinProperty4 = obj_j.SomeOtherField4
    }

The main requirements are: Property names, types and order in the anonymous objects you're joining on must match.

You CAN'T use ANDs, ORs, etc. in joins. Just object1 equals object2.

More advanced stuff in this LinqPad example:

class c1 
    {
    public int someIntField;
    public string someStringField;
    }
    
class c2 
    {
    public Int64 someInt64Property {get;set;}
    private object someField;
    public string someStringFunction(){return someField.ToString();}
    }
    
void Main()
{
    var set1 = new List<c1>();
    var set2 = new List<c2>();
    
    var query = from obj_i in set1
    join obj_j in set2 on 
        new { 
                JoinProperty1 = (Int64) obj_i.someIntField,
                JoinProperty2 = obj_i.someStringField
            } 
        equals 
        new { 
                JoinProperty1 = obj_j.someInt64Property,
                JoinProperty2 = obj_j.someStringFunction()
            }
    select new {obj1 = obj_i, obj2 = obj_j};
}

Addressing names and property order is straightforward, addressing types can be achieved via casting/converting/parsing/calling methods etc. This might not always work with LINQ to EF or SQL or NHibernate, most method calls definitely won't work and will fail at run-time, so YMMV (Your Mileage May Vary). This is because they are copied to public read-only properties in the anonymous objects, so as long as your expression produces values of correct type the join property - you should be fine.

actually, your code is not working because when you write:

$.post("someurl.php",someData,doSomething(data, myDiv),"json"); 

you place a function call as the third parameter rather than a function reference.

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current'); 

http://jsfiddle.net/RmF57/

I use what is basically David Sickmiller's answer with a little more automation. I create a (non-executable) file at the top level of my project named activate with the following contents:

[ -n "$BASH_SOURCE" ] \
    || { echo 1>&2 "source (.) this with Bash."; exit 2; }
(
    cd "$(dirname "$BASH_SOURCE")"
    [ -d .build/virtualenv ] || {
        virtualenv .build/virtualenv
        . .build/virtualenv/bin/activate
        pip install -r requirements.txt
    }
)
. "$(dirname "$BASH_SOURCE")/.build/virtualenv/bin/activate"

(As per David's answer, this assumes you're doing a pip freeze > requirements.txt to keep your list of requirements up to date.)

The above gives the general idea; the actual activate script (documentation) that I normally use is a bit more sophisticated, offering a -q (quiet) option, using python when python3 isn't available, etc.

This can then be sourced from any current working directory and will properly activate, first setting up the virtual environment if necessary. My top-level test script usually has code along these lines so that it can be run without the developer having to activate first:

cd "$(dirname "$0")"
[[ $VIRTUAL_ENV = $(pwd -P) ]] || . ./activate

Sourcing ./activate, not activate, is important here because the latter will find any other activate in your path before it will find the one in the current directory.

for new version of Wamp

I solved this problem like this.

1. setImage to UIImageView (with UIViewContentModeScaleAspectFit)
2. get imageSize (CGSize imageSize = imageView.image.size)
3. UIImageView resize. [imageView sizeThatFits:imageSize]
4. move position where you want.

I wanted to put UIView on the top center of UICollectionViewCell. so, I used this function.

- (void)setImageToCenter:(UIImageView *)imageView
{
    CGSize imageSize = imageView.image.size;
    [imageView sizeThatFits:imageSize];
    CGPoint imageViewCenter = imageView.center;
     imageViewCenter.x = CGRectGetMidX(self.contentView.frame);
    [imageView setCenter:imageViewCenter];
}

It works for me.

If there is a strong concern about speed and performance, the best approach is to verify the code produced by the compiler at the assembly level.

For instance, the following code shows that the "do-while" is a bit faster. This because the "jmp" instruction is not used by the "do-while" loop.

BTW, in this specific example, the worst case is given by the "for" loop. :))

int main(int argc, char* argv[])
{
    int i;
    char x[100];

    // "FOR" LOOP:
    for (i=0; i<100; i++ )
    {
        x[i] = 0;
    }

    // "WHILE" LOOP:
    i = 0;
    while (i<100 )
    {
        x[i++] = 0;
    }

    // "DO-WHILE" LOOP:
    i = 0;
    do
    {
        x[i++] = 0;
    }
    while (i<100);

Message queues are ideal for requests which may take a long time to process. Requests are queued and can be processed offline without blocking the client. If the client needs to be notified of completion, you can provide a way for the client to periodically check the status of the request.

Message queues also allow you to scale better across time. It improves your ability to handle bursts of heavy activity, because the actual processing can be distributed across time.

Note that message queues and web services are orthogonal concepts, i.e. they are not mutually exclusive. E.g. you can have a XML based web service which acts as an interface to a message queue. I think the distinction your looking for is Message Queues versus Request/Response, the latter is when the request is processed synchronously.

Generally to get the current week number (starts from Sunday):

from datetime import *
today = datetime.today()
print today.strftime("%U")

I use this and it works right

@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
    return this.idOdon;
}

All above not worked for me, but this was: Check that the name of Root element of class is exactly like the one from XML case sensitive.

M-x customize-face RET default will allow you to set the face default face, on which all other faces base on. There you can set the font-size.

Here is what is in my .emacs. actually, color-theme will set the basics, then my custom face setting will override some stuff. the custom-set-faces is written by emacs's customize-face mechanism:

;; my colour theme is whateveryouwant :)
(require 'color-theme)
(color-theme-initialize)
(color-theme-whateveryouwant)

(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.

Although I already wrote an overview of different kinds of popups, most people just need an Alert.

How to implement a popup dialog box

class ViewController: UIViewController {

    @IBAction func showAlertButtonTapped(_ sender: UIButton) {

        // create the alert
        let alert = UIAlertController(title: "My Title", message: "This is my message.", preferredStyle: UIAlertController.Style.alert)

        // add an action (button)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: nil))

        // show the alert
        self.present(alert, animated: true, completion: nil)
    }
}

My fuller answer is here.

I'm using laravel 7.x and this problem arose.. the following fixed it:

go to kernel.php and add these 2 classes to protected $middleware

\Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class,

You just use dangerouslySetInnerHTML method of React

<div dangerouslySetInnerHTML={{ __html: htmlString }} />

Or you can implement more with this easy way: Render the HTML raw in React app

You need to tell it which index in data to use, or double loop through all.

E.g., to get the values in the 4th index in the outside array.:

foreach($user->data[3]->values as $values)
{
     echo $values->value . "\n";
}

To go through all:

foreach($user->data as $mydata)
{
    foreach($mydata->values as $values) {
        echo $values->value . "\n";
    }

}   

I do not understand why the answers are so complex. In Javascript, primitives (strings, numbers, etc) are passed by value, and copied. Objects, including arrays, are passed by reference. In any case, assignment of a new value or object reference to 'a' will not change 'b'. But changing the contents of 'a' will change the contents of 'b'.

var a = 'a'; var b = a; a = 'c'; // b === 'a'

var a = {a:'a'}; var b = a; a = {c:'c'}; // b === {a:'a'} and a = {c:'c'}

var a = {a:'a'}; var b = a; a.a = 'c'; // b.a === 'c' and a.a === 'c'

Paste any of the above lines (one at a time) into node or any browser javascript console. Then type any variable and the console will show it's value.

Use:

subA.tick_params(labelsize=6)

Answer is YES

<html>

To expand a bit on why the error happened: A forward slash at the beginning of a path means "start from the root of the filesystem, and look for the given path". No forward slash means "start from the current working directory, and look for the given path".

The path

/tmp/test.jpg

thus translates to looking for the file test.jpg in the tmp folder at the root of the filesystem (e.g. c:\ on windows, / on *nix), instead of the webapp folder. Adding a period (.) in front of the path explicitly changes this to read "start from the current working directory", but is basically the same as leaving the forward slash out completely.

./tmp/test.jpg = tmp/test.jpg

The problem was that one of the nested objects in Foo didn't have any getter/setter
