React.MouseEvent works for me:

private onClick = (e: React.MouseEvent<HTMLInputElement>) => {
  let button = e.target as HTMLInputElement;
}

plt.figure(figsize=(15,10))
graph = sns.barplot(x='name_column_x_axis', y="name_column_x_axis", data = dataframe_name ,  color="salmon")
for p in graph.patches:
        graph.annotate('{:.0f}'.format(p.get_height()), (p.get_x()+0.3, p.get_height()),
                    ha='center', va='bottom',
                    color= 'black')

we have to create your own docker volume mapped with the host directory before we mention in the docker-compose.yml as external

1.Create volume named share

docker volume create --driver local \
--opt type=none \
--opt device=/home/mukundhan/share \
--opt o=bind share

2.Use it in your docker-compose

version: "3"

volumes:
  share:
    external: true

services:
  workstation:
    container_name: "workstation"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
      - ./source:/source:consistent
    working_dir: /source
    ipc: host
    privileged: true
    shm_size: '2gb'
  db:
    container_name: "db"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
    working_dir: /source
    ipc: host

This way we can share the same directory with many services running in different containers

I took a look at how YouTube solves it on their homepage and simplified it:

.multine-ellipsis {
  -webkit-box-orient: vertical;
  display: -webkit-box;
  -webkit-line-clamp: 2;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: normal;
}

This will allow 2 lines of code and then append an ellipsis.

This should works

$token = "YOUR_BEARER_AUTH_TOKEN";
//setup the request, you can also use CURLOPT_URL
$ch = curl_init('API_URL');

// Returns the data/output as a string instead of raw data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//Set your auth headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Authorization: Bearer ' . $token
   ));

// get stringified data/output. See CURLOPT_RETURNTRANSFER
$data = curl_exec($ch);

// get info about the request
$info = curl_getinfo($ch);
// close curl resource to free up system resources
curl_close($ch);

To have the active tab also styled, merge the answer from this thread, from Mansukh Khandhar, with this other answer, from lmgonzalves:

.nav-tabs > li.active > a {
  background-color: yellow !important;
  border: medium none;
  border-radius: 0;
}

as header

AUTH=$(echo -ne "$BASIC_AUTH_USER:$BASIC_AUTH_PASSWORD" | base64 --wrap 0)

curl \
  --header "Content-Type: application/json" \
  --header "Authorization: Basic $AUTH" \
  --request POST \
  --data  '{"key1":"value1", "key2":"value2"}' \
  https://example.com/

window.onload = function() {
    var userImage = document.getElementById('imageOtherUser');
    var hangoutButton = document.getElementById("hangoutButtonId");
    userImage.onclick = function() {
       hangoutButton.click(); // this will trigger the click event
    };
};

this will do the trick

The problem, it seems, is that Mobile Safari will refuse to obey the width of your iFrame if the document it contains is wider than what you have specified. Example:

http://jsbin.com/hapituto/1

On a desktop browser, you will see an iFrame and a Div both set to 300px. The contents is wider so you can scroll the iFrame.

On mobile safari, however, you will notice that the iFrame is auto-expanded to the width of the content.

My guess is that this is a workaround for long-standing issues with scrolling content within a page. In the past, if you had a large scrolling iframe on a touch device, you'd get 'stuck' in the iframe as that would be scrolling instead of the page itself. It appears Apple has decided that the default behavior of an iFrame is 'no scroll' and expands to prevent it.

One option may be this workaround. Instead of assuming the iFrame will scroll, place the iframe in a DIV that you do have control over and let that scroll.

example: http://jsbin.com/zakedaja/1

Example markup:

<div style="overflow: scroll; -webkit-overflow-scrolling: touch; width: 300px;">
   <iframe src="http://jsbin.com/roredora/1/" style="width: 600px;"></iframe>
</div>

On mobile safari, you can now scroll the contents of the now fully-expanded iFrame via the div that is containing it.

The catch: This looks really ugly on a desktop browser, as now you have double scrollbars. So you may have to do some browser detection with JS to get around this.

EDIT: Kanbanize is a commercial product and offers a 30 day free trial.

Disclosing: I am a co-founder of http://kanbanize.com/

Mark, I understand your desire to find the perfect application with all these features inside, but I really doubt that you will get it for free. There's a bunch of super cool apps (including Kanbanize) out there, but none of them is completely free.

Be careful what you call a Kanban board and what not, though. Trello is definitely NOT a kanban system (no WIP limits, no analytics, etc.). It is a great visual management system, but not a Kanban one.

Finally, to answer your question, tools that deserve attention in my opinion are: Kanbanize (of course), LeanKit, KanbanTool, Kanbanery and probably a few others. My personal bias is that LeanKit is the most advanced to date followed by Kanbanize and KanbanTool.

I hope that helps.

I suspect looking at the excerpt that the function trustSrc from trustSrc(currentProject.url) is not defined in the controller.

You need to inject the $sce service in the controller and trustAsResourceUrl the url there.

In the controller:

function AppCtrl($scope, $sce) {
    // ...
    $scope.setProject = function (id) {
      $scope.currentProject = $scope.projects[id];
      $scope.currentProjectUrl = $sce.trustAsResourceUrl($scope.currentProject.url);
    }
}

In the Template:

<iframe ng-src="{{currentProjectUrl}}"> <!--content--> </iframe>

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

I've found examples, where PyPy is slower than Python. But: Only on Windows.

C:\Users\User>python -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 294 msec per loop

C:\Users\User>pypy -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 1.33 sec per loop

So, if you think of PyPy, forget Windows. On Linux, you can achieve awesome accelerations. Example (list all primes between 1 and 1,000,000):

from sympy import sieve
primes = list(sieve.primerange(1, 10**6))

This runs 10(!) times faster on PyPy than on Python. But not on windows. There it is only 3x as fast.

When you use Apache with mod_php apache is enforced in prefork mode, and not worker. As, even if php5 is known to support multi-thread, it is also known that some php5 libraries are not behaving very well in multithreaded environments (so you would have a locale call on one thread altering locale on other php threads, for example).

So, if php is not running in cgi way like with php-fpm you have mod_php inside apache and apache in prefork mode. On your tests you have simply commented the prefork settings and increased the worker settings, what you now have is default values for prefork settings and some altered values for the shared ones :

StartServers       20
MinSpareServers    5
MaxSpareServers    10
MaxClients         1024
MaxRequestsPerChild  0

This means you ask apache to start with 20 process, but you tell it that, if there is more than 10 process doing nothing it should reduce this number of children, to stay between 5 and 10 process available. The increase/decrease speed of apache is 1 per minute. So soon you will fall back to the classical situation where you have a fairly low number of free available apache processes (average 2). The average is low because usually you have something like 5 available process, but as soon as the traffic grows they're all used, so there's no process available as apache is very slow in creating new forks. This is certainly increased by the fact your PHP requests seems to be quite long, they do not finish early and the apache forks are not released soon enough to treat another request.

See on the last graphic the small amount of green before the red peak? If you could graph this on a 1 minute basis instead of 5 minutes you would see that this green amount was not big enough to take the incoming traffic without any error message.

Now you set 1024 MaxClients. I guess the cacti graph are not taken after this configuration modification, because with such modification, when no more process are available, apache would continue to fork new children, with a limit of 1024 busy children. Take something like 20MB of RAM per child (or maybe you have a big memory_limit in PHP and allows something like 64MB or 256MB and theses PHP requests are really using more RAM), maybe a DB server... your server is now slowing down because you have only 768MB of RAM. Maybe when apache is trying to initiate the first 20 children you already reach the available RAM limit.

So. a classical way of handling that is to check the amount of memory used by an apache fork (make some top commands while it is running), then find how many parallel request you can handle with this amount of RAM (that mean parallel apache children in prefork mode). Let's say it's 12, for example. Put this number in apache mpm settings this way:

<IfModule prefork.c>
  StartServers       12
  MinSpareServers    12
  MaxSpareServers    12
  MaxClients         12
  MaxRequestsPerChild  300
</IfModule>

That means you do not move the number of fork while traffic increase or decrease, because you always want to use all the RAM and be ready for traffic peaks. The 300 means you recyclate each fork after 300 requests, it's better than 0, it means you will not have potential memory leaks issues. MaxClients is set to 12 25 or 50 which is more than 12 to handle the ListenBacklog queue, which can enqueue some requests, you may take a bigger queue, but you would get some timeouts maybe (removed this strange sentende, I can't remember why I said that, if more than 12 requests are incoming the next one will be pushed in the Backlog queue, but you should set MaxClient to your targeted number of processes).

And yes, that means you cannot handle more than 12 parallel requests.

If you want to handle more requests:

• buy some more RAM
• try to use apache in worker mode, but remove mod_php and use php as a parallel daemon with his own pooler settings (this is called php-fpm), connect it with fastcgi. Note that you will certainly need to buy some RAM to allow a big number of parallel php-fpm process, but maybe less than with mod_php
• Reduce the time spent in your php process. From your cacti graphs you have to potential problems: a real traffic peak around 11:25-11:30 or some php code getting very slow. Fast requests will reduce the number of parallel requests.

If your problem is really traffic peaks, solutions could be available with caches, like a proxy-cache server. If the problem is a random slowness in PHP then... it's an application problem, do you do some HTTP query to another site from PHP, for example?

And finally, as stated by @Jan Vlcinsky you could try nginx, where php will only be available as php-fpm. If you cannot buy RAM and must handle a big traffic that's definitively desserve a test.

Update: About internal dummy connections (if it's your problem, but maybe not).

Check this link and this previous answer. This is 'normal', but if you do not have a simple virtualhost theses requests are maybe hitting your main heavy application, generating slow http queries and preventing regular users to acces your apache processes. They are generated on graceful reload or children managment.

If you do not have a simple basic "It works" default Virtualhost prevent theses requests on your application by some rewrites:

  RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
  RewriteRule .* - [F,L]

Update:

Having only one Virtualhost does not protect you from internal dummy connections, it is worst, you are sure now that theses connections are made on your unique Virtualhost. So you should really avoid side effects on your application by using the rewrite rules.

Reading your cacti graphics, it seems your apache is not in prefork mode bug in worker mode. Run httpd -l or apache2 -l on debian, and check if you have worker.c or prefork.c. If you are in worker mode you may encounter some PHP problems in your application, but you should check the worker settings, here is an example:

<IfModule worker.c>
  StartServers           3
  MaxClients           500
  MinSpareThreads       75
  MaxSpareThreads      250 
  ThreadsPerChild       25
  MaxRequestsPerChild  300
</IfModule>

You start 3 processes, each containing 25 threads (so 3*25=75 parallel requests available by default), you allow 75 threads doing nothing, as soon as one thread is used a new process is forked, adding 25 more threads. And when you have more than 250 threads doing nothing (10 processes) some process are killed. You must adjust theses settings with your memory. Here you allow 500 parallel process (that's 20 process of 25 threads). Your usage is maybe more:

<IfModule worker.c>
  StartServers           2
  MaxClients           250
  MinSpareThreads       50
  MaxSpareThreads      150 
  ThreadsPerChild       25
  MaxRequestsPerChild  300
</IfModule>

This shows how to run the playbooks on the target server itself.

This is a bit trickier if you want to use a local connection. But this should be OK if you use a variable for the hosts setting and in the hosts file create a special entry for localhost.

In (all) playbooks have the hosts: line set to:

- hosts: "{{ target | default('no_hosts')}}"

In the inventory hosts file add an entry for the localhost which sets the connection to be local:

[localhost]
127.0.0.1  ansible_connection=local

Then on the command line run commands explicitly setting the target - for example:

$ ansible-playbook --extra-vars "target=localhost" test.yml

This will also work when using ansible-pull:

$ ansible-pull -U <git-repo-here> -d ~/ansible --extra-vars "target=localhost" test.yml

If you forget to set the variable on the command line the command will error safely (as long as you've not created a hosts group called 'no_hosts'!) with a warning of:

skipping: no hosts matched

And as mentioned above you can target a single machine (as long as it is in your hosts file) with:

$ ansible-playbook --extra-vars "target=server.domain" test.yml

or a group with something like:

$ ansible-playbook --extra-vars "target=web-servers" test.yml

I believe that must-revalidate means :

Once the cache expires, refuse to return stale responses to the user even if they say that stale responses are acceptable.

Whereas no-cache implies :

must-revalidate plus the fact the response becomes stale right away.

If a response is cacheable for 10 seconds, then must-revalidate kicks in after 10 seconds, whereas no-cache implies must-revalidate after 0 seconds.

At least, that's my interpretation.

in my case, only height: 100vh fix the problem with the expected behavior

The Most Elegant Solutions...

app.service('svc', function(){ this.attr = []; return this; });
app.controller('ctrl', function($scope, svc){
    $scope.attr = svc.attr || [];
    $scope.$watch('attr', function(neo, old){ /* if necessary */ });
});
app.run(function($rootScope, svc){
    $rootScope.svc = svc;
    $rootScope.$watch('svc', function(neo, old){ /* change the world */ });
});

Also, I write EDAs (Event-Driven Architectures) so I tend to do something like the following [oversimplified version]:

var Service = function Service($rootScope) {
    var $scope = $rootScope.$new(this);
    $scope.that = [];
    $scope.$watch('that', thatObserver, true);
    function thatObserver(what) {
        $scope.$broadcast('that:changed', what);
    }
};

Then, I put a listener in my controller on the desired channel and just keep my local scope up to date this way.

In conclusion, there's not much of a "Best Practice" -- rather, its mostly preference -- as long as you're keeping things SOLID and employing weak coupling. The reason I would advocate the latter code is because EDAs have the lowest coupling feasible by nature. And if you aren't too concerned about this fact, let us avoid working on the same project together.

Hope this helps...

I used this extension method a lot in my project. Hope it will help one of you guys.

public static bool HasClass(this HtmlNode node, params string[] classValueArray)
    {
        var classValue = node.GetAttributeValue("class", "");
        var classValues = classValue.Split(' ');
        return classValueArray.All(c => classValues.Contains(c));
    }

Agile is mostly used technique in project development.In agile technology peoples are switches from one technology to other ..Main purpose is to remove dependancy. Like Peoples shifted from production to development,and development to testing. Thats why dependancy will remove on a single team or person..

SCRUM :

SCRUM is a type of Agile approach. It is a Framework not a Methodology.

It does not provide detailed instructions to what needs to be done rather most of it is dependent on the team that is developing the software. Because the developing the project knows how the problem can be solved that is why much is left on them

Cross-functional and self-organizing teams are essential in case of scrum. There is no team leader in this case who will assign tasks to the team members rather the whole team addresses the issues or problems. It is cross-functional in a way that everyone is involved in the project right from the idea to the implementation of the project.

The advantage of scrum is that a project’s direction to be adjusted based on completed work, not on speculation or predictions.

Roles Involved : Product Owner, Scrum Master, Team Members

Agile Methodology :

Build Software applications that are unpredictable in nature

Iterative and incremental work cadences called sprints are used in this methodology.

Both Agile and SCRUM follows the system -- some of the features are developed as a part of the sprint and at the end of each sprint; the features are completed right from coding, testing and their integration into the product. A demonstration of the functionality is provided to the owner at the end of each sprint so that feedback can be taken which can be helpful for the next sprint.

Manifesto for Agile Development :

1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.

For individual element the code below could be used:

private boolean isElementPresent(By by) {
        try {
            driver.findElement(by);
            return true;
        } catch (NoSuchElementException e) {
            return false;
        }
    }
for (int second = 0;; second++) {
            if (second >= 60){
                fail("timeout");
            }
            try {
                if (isElementPresent(By.id("someid"))){
                    break;
                }
                }
            catch (Exception e) {

            }
            Thread.sleep(1000);
        }

Adding the answer for Windows User for the latest postgres version (>10),

Go to your postgres installation location, and search for pg_hba.conf, you will find it in ..\postgres\data\pg_hba.conf

Open that file with notepad, find this line,

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections: 
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
#..

Change the method from md5 to trust,

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections: 
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# ...

Now go to your SQL Shell(PSQL) and leave everything blank,

Server [localhost]:
Database [postgres]:
Port [8000]:
Username [postgres]: 

It will not ask for password this time, and you will be logged in,

Now run this line, ALTER USER yourusername WITH SUPERUSER

Now you can leave the shell with \q

Again go to the file pg_hba.conf and change METHOD from trust to md5 again, and save it.

Now login with your new user and password and you can check \du for its attributes.

Permissions that Imply Feature Requirements

example, the android.hardware.bluetooth feature was added in Android 2.2 (API level 8), but the bluetooth API that it refers to was added in Android 2.0 (API level 5). Because of this, some apps were able to use the API before they had the ability to declare that they require the API via the system.

To prevent those apps from being made available unintentionally, Google Play assumes that certain hardware-related permissions indicate that the underlying hardware features are required by default. For instance, applications that use Bluetooth must request the BLUETOOTH permission in a element — for legacy apps, Google Play assumes that the permission declaration means that the underlying android.hardware.bluetooth feature is required by the application and sets up filtering based on that feature.

The table below lists permissions that imply feature requirements equivalent to those declared in elements. Note that declarations, including any declared android:required attribute, always take precedence over features implied by the permissions below.

For any of the permissions below, you can disable filtering based on the implied feature by explicitly declaring the implied feature explicitly, in a element, with an android:required="false" attribute. For example, to disable any filtering based on the CAMERA permission, you would add this declaration to the manifest file:

<uses-feature android:name="android.hardware.camera" android:required="false" />


<uses-feature android:name="android.hardware.bluetooth" android:required="false" />
<uses-feature android:name="android.hardware.location" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />
<uses-feature android:name="android.hardware.telephony" android:required="false" />
<uses-feature android:name="android.hardware.wifi" android:required="false" />

Yeap, you just need to make . match newline :

$string =~ /(START)(.+?)(END)/s;

It means the CPU attempted to execute an instruction it didn't understand. This could be caused by corruption I guess, or maybe it's been compiled for the wrong architecture (in which case I would have thought the O/S would refuse to run the executable). Not entirely sure what the root issue is.

Threads share a process and a process runs on a core, but you can use python's multiprocessing module to call your functions in separate processes and use other cores, or you can use the subprocess module, which can run your code and non-python code too.

On modern browsers you can try with the pointer-events css property (but it leads to the impossibility to detect mouse events on the parent node):

p {
    position: relative;
    background-color: blue;
    color:#ffffff;
    padding:0px 10px;
    pointer-events:none;
}
p::before {
    content: attr(data-before);
    margin-left:-10px;
    margin-right:10px;
    position: relative;
    background-color: red;
    padding:0px 10px;
    pointer-events:auto;
}

When the event target is your "p" element, you know it is your "p:before".

If you still need to detect mouse events on the main p, you may consider the possibility to modify your HTML structure. You can add a span tag and the following style:

p span {
    background:#393;
    padding:0px 10px;
    pointer-events:auto;
}

The event targets are now both the "span" and the "p:before" elements.

It is very simple way to make individual file non-arc.

Follow below steps :

Disable ARC on individual file:

1. Select desired files at Target/Build Phases/Compile Sources in Xcode

2. Select .m file which you want make it NON-ARC PRESS ENTER Type -fno-objc-arc

Non ARC file to ARC project flag : -fno-objc-arc

ARC file to non ARC project flag : -fobjc-arc

after hardware check on the server and it was found out that memory had gone bad, replaced the memory and the server is now fully accessible.

str = 'Hello World String'    
print(str(10)+' Good day!!')

Even I faced this issue with the above code as we are shadowing str() function.

Solution is:

string1 = 'Hello World String'
print(str(10)+' Good day!!')

The file format would permit up to 255-character worksheet names, but if the Excel UI doesn't want you exceeding 31 characters, don't try to go beyond 31. App's full of weird undocumented limits and quirks, and feeding it files that are within spec but not within the range of things the testers would have tested usually causes REALLY strange behavior. (Personal favorite example: using the Excel 4.0 bytecode for an if() function, in a file with an Excel 97-style stringtable, disabled the toolbar button for bold in Excel 97.)

Scrum is a type of Agile method just like an apple is a type of fruit. Scrum is not the only Agile method though. The popular ones are:

• Scrum
• eXtreme Programming (XP)
• Kanban

I'm sure there are more Agile methods but these are what I have experience with.

The trick with relying upon IIS is that IIS bindings can be different from your public URLs (WCF I'm looking at you), especially with multi-homed production machines. I tend to vector toward using configuration to explicitly define the "base" url for external purposes as that tends to be a bit more successful than extracting it from the Request object.

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

Getting Started - HTML Agility Pack

// From File
var doc = new HtmlDocument();
doc.Load(filePath);

// From String
var doc = new HtmlDocument();
doc.LoadHtml(html);

// From Web
var url = "http://html-agility-pack.net/";
var web = new HtmlWeb();
var doc = web.Load(url);

You could use this:

 public static string StripHTML(string HTMLText, bool decode = true)
        {
            Regex reg = new Regex("<[^>]+>", RegexOptions.IgnoreCase);
            var stripped = reg.Replace(HTMLText, "");
            return decode ? HttpUtility.HtmlDecode(stripped) : stripped;
        }

Updated

Thanks for the comments I have updated to improve this function

How about something like: Using HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
foreach (HtmlNode table in doc.DocumentNode.SelectNodes("//table")) {
    Console.WriteLine("Found: " + table.Id);
    foreach (HtmlNode row in table.SelectNodes("tr")) {
        Console.WriteLine("row");
        foreach (HtmlNode cell in row.SelectNodes("th|td")) {
            Console.WriteLine("cell: " + cell.InnerText);
        }
    }
}

Note that you can make it prettier with LINQ-to-Objects if you want:

var query = from table in doc.DocumentNode.SelectNodes("//table").Cast<HtmlNode>()
            from row in table.SelectNodes("tr").Cast<HtmlNode>()
            from cell in row.SelectNodes("th|td").Cast<HtmlNode>()
            select new {Table = table.Id, CellText = cell.InnerText};

foreach(var cell in query) {
    Console.WriteLine("{0}: {1}", cell.Table, cell.CellText);
}

I think the problem can be because of the NAT. Normally the DNS clients make requests via UDP. But when the DNS server is behind the NAT the UDP requests will not work.

Given your factorGenerator function, here is a divisorGen that should work:

def divisorGen(n):
    factors = list(factorGenerator(n))
    nfactors = len(factors)
    f = [0] * nfactors
    while True:
        yield reduce(lambda x, y: x*y, [factors[x][0]**f[x] for x in range(nfactors)], 1)
        i = 0
        while True:
            f[i] += 1
            if f[i] <= factors[i][1]:
                break
            f[i] = 0
            i += 1
            if i >= nfactors:
                return

The overall efficiency of this algorithm will depend entirely on the efficiency of the factorGenerator.

Although it was designed for .NET web-testing, I've been using the WatiN framework for this purpose. Since it is DOM-based, it is pretty easy to capture HTML, text, or images. Recentely, I used it to dump a list of links from a MediaWiki All Pages namespace query into an Excel spreadsheet. The following VB.NET code fragement is pretty crude, but it works.

Sub GetLinks(ByVal PagesIE As IE, ByVal MyWorkSheet As Excel.Worksheet)

    Dim PagesLink As Link
    For Each PagesLink In PagesIE.TableBodies(2).Links
        With MyWorkSheet
            .Cells(XLRowCounterInt, 1) = PagesLink.Text
            .Cells(XLRowCounterInt, 2) = PagesLink.Url
        End With
        XLRowCounterInt = XLRowCounterInt + 1
    Next
End Sub

I took all of the podcasts from the answers scoring 5 or better (and those in the original question) and added them to an aggregated page on Cullect.com:

It provides a handy way to get a glimpse of these podcasts as well as a way to preview them if you're in a hurry or don't want to wade through all of the duplicates in the answers. I'm currently set up as the only curator of the "cullection", but if someone else wants to help keep it adjusted as the answers change, let me know.

Here's an example of using text-overflow:

  overflow: hidden;_x000D_
  white-space: nowrap;_x000D_
  text-overflow: ellipsis;_x000D_
}

<span class="text">Hello world this is a long sentence</span>

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

I tested and the script run ok!

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

Calling ToString() on an object presumes that the object is not null (since an object needs to exist to call an instance method on it). Convert.ToString(obj) doesn't need to presume the object is not null (as it is a static method on the Convert class), but instead will return String.Empty if it is null.

mysql -u username -ppassword dbname < /path/file-name.sql

example

mysql -u root -proot product < /home/myPC/Downloads/tbl_product.sql

Use this from terminal

Try this.

<span style="padding-right:3px; padding-top: 3px; display:inline-block;">

<img class="manImg" src="images/ico_mandatory.gif"></img>

</span>

You could also, higlight the text you want to change, then navigate to - 'Edit' > 'Convert Case to' choose UPPERCASE or lowercase (as required).

protected void gvBill_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)

            Total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "InvMstAmount"));
        else if (e.Row.RowType == DataControlRowType.Footer)

            e.Row.Cells[7].Text = String.Format("{0:0}", "<b>" + Total + "</b>");
    }

Quick answer for single line span

Make the child (in this case a span) the same line-height as the parent <div>'s height

<div class="parent">
  <span class="child">Yes mom, I did my homework lol</span>
</div>

You should then add the CSS rules

.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }

Or you can target it with a child selector

.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }

Background on my own use of this

I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)

HTML

<div class="international">        
  <span class="intlFlag">
    {{flag}}        
  </span>

  <span class="intlCurrent">
    {{country}}
  </span>

  <span class="intlButton">
    <i class="fa fa-globe"></i>
  </span> 
</div>

CSS (option for multiple spans in a div)

.international {
  height: 42px;
}

.international > span {
  line-height: 42px;
}

In this case if I just had one span I could have added the CSS rule directly to that span.

CSS (option for one specific span)

.intlFlag { line-height: 42px; }

Here is how it displayed for me

To make it short you could use "companion object" to get into Kotlin static world like :

  companion object {
    const val TAG = "tHomeFragment"
    fun newInstance() = HomeFragment()
}

and to make a constant field use "const val" as in the code. but try to avoid the static classes as it is making difficulties in unit testing using Mockito!.

I use objects JSON style for dumb structs (no member functions).

I think the confusing aspect of this is the fact that BootStrap 3 is a mobile first responsive system and fails to explain how this affects the col-xx-n hierarchy in that part of the Bootstrap documentation. This makes you wonder what happens on smaller devices if you choose a value for larger devices and makes you wonder if there is a need to specify multiple values. (You don't)

I would attempt to clarify this by stating that... Lower grain types (xs, sm) attempt retain layout appearance on smaller screens and larger types (md,lg) will display correctly only on larger screens but will wrap columns on smaller devices. The values quoted in previous examples refer to the threshold as which bootstrap degrades the appearance to fit the available screen estate.

What this means in practice is that if you make the columns col-xs-n then they will retain correct appearance even on very small screens, until the window drops to a size that is so restrictive that the page cannot be displayed correctly. This should mean that devices that have a width of 768px or less should show your table as you designed it rather than in degraded (single or wrapped column form). Obviously this still depends on the content of the columns and that's the whole point. If the page attempts to display multiple columns of large data, side by side on a small screen then the columns will naturally wrap in a horrible way if you did not account for it. Therefore, depending on the data within the columns you can decide the point at which the layout is sacificed to display the content adequately.

e.g. If your page contains three col-sm-n columns bootstrap would wrap the columns into rows when the page width drops below 992px. This means that the data is still visible but will require vertical scrolling to view it. If you do not want your layout to degrade, choose xs (as long as your data can be adequately displayed on a lower resolution device in three columns)

If the horizontal position of the data is important then you should try to choose lower granularity values to retain the visual nature. If the position is less important but the page must be visible on all devices then a higher value should be used.

If you choose col-lg-n then the columns will display correctly until the screen width drops below the xs threshold of 1200px.

As with many questions lately, Java 8 to the rescue:

Java 8 added a new static method to java.lang.String which does exactly what you want:

public static String join(CharSequence delimeter, CharSequence... elements);

Using it:

String s = String.join(", ", new String[] {"Hello", "World", "!"});

Results in:

"Hello, World, !"

I use a modified version of this:

function getElementsByClass(nameOfClass) {    
  var temp, all, elements;

  all = document.getElementsByTagName("*");
  elements = [];

  for(var a=0;a<all.length;a++) {
    temp = all[a].className.split(" ");
    for(var b=0;b<temp.length;b++) {
      if(temp[b]==nameOfClass) { 
        elements.push(ALL[a]); 
        break; 
      }
    }
  }
  return elements;
};

And JQuery will do this really easily too.

Just a little addition to the answer of @dAm2k :

In addition to sudo apt-get remove --purge mysql\*

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

Add the css styling text-align: center to the control.

Ideally you would do this through a css class assigned to the control, but if you must do it directly, here is an example:

<asp:TextBox ID="myTextBox" runat="server" style="text-align: center"></asp:TextBox>

You're trying to open each file twice! First you do:

infile=open('110331_HS1A_1_rtTA.result','r')

and then you pass infile (which is a file object) to the open function again:

with open (infile, mode='r', buffering=-1)

open is of course expecting its first argument to be a file name, not an opened file!

Open the file once only and you should be fine.

Convert the excel file to .csv file (comma separated value file) and now you can easily be able to read it.

I know I am very late to answer this question.
But would like to add for further references to the give answers.
DesiredCapabilities are used like setting your config with key-value pair.
Below is an example related to Appium used for Automating Mobile platforms like Android and IOS.
So we generally set DesiredCapabilities for conveying our WebDriver for specific things we will be needing to run our test to narrow down the performance and to increase the accuracy.

So we set our DesiredCapabilities as:

// Created object of DesiredCapabilities class.
DesiredCapabilities capabilities = new DesiredCapabilities();

// Set android deviceName desired capability. Set your device name.
capabilities.setCapability("deviceName", "your Device Name");

// Set BROWSER_NAME desired capability.
capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome");

// Set android VERSION desired capability. Set your mobile device's OS version.
capabilities.setCapability(CapabilityType.VERSION, "5.1");

// Set android platformName desired capability. It's Android in our case here.
capabilities.setCapability("platformName", "Android");

// Set android appPackage desired capability.

//You need to check for your appPackage Name for your app, you can use this app for that APK INFO

// Set your application's appPackage if you are using any other app. 
capabilities.setCapability("appPackage", "com.android.appPackageName");

// Set android appActivity desired capability. You can use the same app for finding appActivity of your app
capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");

This DesiredCapabilities are very specific to Appium on Android Platform. For more you can refer to the official site of Selenium desiredCapabilities class

The following will list the methods that the User class has that the base Object class does not have...

>> User.methods - Object.methods
=> ["field_types", "maximum", "create!", "active_connections", "to_dropdown",
    "content_columns", "su_pw?", "default_timezone", "encode_quoted_value", 
    "reloadable?", "update", "reset_sequence_name", "default_timezone=", 
    "validate_find_options", "find_on_conditions_without_deprecation", 
    "validates_size_of", "execute_simple_calculation", "attr_protected", 
    "reflections", "table_name_prefix", ...

Note that methods is a method for Classes and for Class instances.

Here's the methods that my User class has that are not in the ActiveRecord base class:

>> User.methods - ActiveRecord::Base.methods
=> ["field_types", "su_pw?", "set_login_attr", "create_user_and_conf_user", 
    "original_table_name", "field_type", "authenticate", "set_default_order",
    "id_name?", "id_name_column", "original_locking_column", "default_order",
    "subclass_associations",  ... 
# I ran the statements in the console.

Note that the methods created as a result of the (many) has_many relationships defined in the User class are not in the results of the methods call.

Added Note that :has_many does not add methods directly. Instead, the ActiveRecord machinery uses the Ruby method_missing and responds_to techniques to handle method calls on the fly. As a result, the methods are not listed in the methods method result.

2. you can check hidden code for those modules using inspect

1) inspect:

use inpsect module to explore code you want... NOTE: you can able to explore code only for modules (aka) packages you have imported

for eg:

  >>> import randint  
  >>> from inspect import getsource
  >>> getsource(randint) # here i am going to explore code for package called `randint`

2) help():

you can simply use help() command to get help about builtin functions as well its code.

for eg: if you want to see the code for str() , simply type - help(str)

it will return like this,

>>> help(str)
Help on class str in module __builtin__:

class str(basestring)
 |  str(object='') -> string
 |
 |  Return a nice string representation of the object.
 |  If the argument is a string, the return value is the same object.
 |
 |  Method resolution order:
 |      str
 |      basestring
 |      object
 |
 |  Methods defined here:
 |
 |  __add__(...)
 |      x.__add__(y) <==> x+y
 |
 |  __contains__(...)
 |      x.__contains__(y) <==> y in x
 |
 |  __eq__(...)
 |      x.__eq__(y) <==> x==y
 |
 |  __format__(...)
 |      S.__format__(format_spec) -> string
 |
 |      Return a formatted version of S as described by format_spec.
 |
 |  __ge__(...)
 |      x.__ge__(y) <==> x>=y
 |
 |  __getattribute__(...)

Lockheed Martin uses a 3-prefix naming scheme which was wonderful to work with, especially when reading others' code.

   Scope          Reference Type(*Case-by-Case)   Type

   member   m     pointer p                       integer n
   argument a     reference r                     short   n
   local    l                                     float   f
                                                  double  f
                                                  boolean b

So...

int A::methodCall(float af_Argument1, int* apn_Arg2)
{
    lpn_Temp = apn_Arg2;
    mpf_Oops = lpn_Temp;  // Here I can see I made a mistake, I should not assign an int* to a float*
}

Take it for what's it worth.

I think it is because % has often be associated with the modulus operator in many programming languages.

It is the case, e.g., in C, C++, C# and Java, and many other languages which derive their syntax from C (C itself took it from B).

None of the above worked on Sublime Text 3 on Windows 10, Ctrl + Shift + ' with the Emmet Sublime Text 3 plugin works great and was the only working solution for me. Ctrl + Shift + T re-opens the last closed item and to my knowledge of Sublime, has done so since early builds of ST3 or late builds of ST2.

I think you're confused by different paradigms here. First, war files and server deployment -- those things belong to Java Enterprise Edition (Java EE). These concepts have no real place in a spring-boot application, which follows a different model.

Spring-boot is responsible for creating an embedded container and running your services within it directly from standard jar files (although it can do a lot more). I think the intent of this model is to support micro-service development -- where each service has its own container and is completely self contained. You can use your code to generate Java EE apps too, but that would be silly considering that spring-boot is a lot easier (for certain types of application/service).

So, given this information you now have to decide what paradigm you're going to follow, and you need to follow that and only that.

Spring-boot is executable -- you just have to run the main method in the App class which you can do from the command line or using your favourite IDE or maven or gradle (tip: maven is the right answer). This will bring up a tomcat server (by default) and your service will be available within it. Given the configuration you posted above your service should be available at: http://localhost:7777/context/help -- the context is meant to be replaced with your context name, which you haven't shared.

You aren't meant to be creating a war, running tomcat, or deploying anything. None of that is necessary in spring-boot. The packaging in your pom should be jar, not war and the scope of the spring-boot-starter-tomcat should be removed -- it certainly isn't provided.

When you run your main method, the console output should tell you the context that you've registered; use that to get the URL right.

Having said all that, spring-boot has to exist in a JEE world for now (until it is widely adopted). For that reason, the spring people have documented an approach to building a war rather than an executable jar, for deployment to a servlet or JEE container. This allows a lot of the spring-boot tech to be used in environments where there are restrictions against using anything but wars (or ears). However, this is a just a response to the fact that such environments are quite common, and is not seen as a necessary, or even desirable, part of the solution.

You can use istringstream.

string s = "10";

// create an input stream with your string.
istringstream is(str);

int i;
// use is like an input stream
is >> i;

The trick is to use the power of the browser to decode the special HTML characters, but not allow the browser to execute the results as if it was actual html... This function uses a regex to identify and replace encoded HTML characters, one character at a time.

function unescapeHtml(html) {
    var el = document.createElement('div');
    return html.replace(/\&[#0-9a-z]+;/gi, function (enc) {
        el.innerHTML = enc;
        return el.innerText
    });
}

I realize this question has already been answered, however, I had a different solution:

If you are writing a script where you drop the tables without recreating them, those tables will show as missing if you try to reference them later on.

Note: This isn't going to happen with a script that is constantly ran, but sometimes it's easier to have a script with queries to reerence than to type them everytime.

Yes - you can create encapsulated property, but it's not been done with access modifiers (public|private) at least not with ES6.

Here is a simple example how it can be done with ES6:

1 Create class using class word

2 Inside it's constructor declare block-scoped variable using let OR const reserved words -> since they are block-scope they cannot be accessed from outside (encapsulated)

3 To allow some access control (setters|getters) to those variables you can declare instance method inside it's constructor using: this.methodName=function(){} syntax

"use strict";
    class Something{
        constructor(){
            //private property
            let property="test";
            //private final (immutable) property
            const property2="test2";
            //public getter
            this.getProperty2=function(){
                return property2;
            }
            //public getter
            this.getProperty=function(){
                return property;
            }
            //public setter
            this.setProperty=function(prop){
                property=prop;
            }
        }
    }

Now lets check it:

var s=new Something();
    console.log(typeof s.property);//undefined 
    s.setProperty("another");//set to encapsulated `property`
    console.log(s.getProperty());//get encapsulated `property` value
    console.log(s.getProperty2());//get encapsulated immutable `property2` value

I ended up with

const regexBase = '(?:\\+?(\\d{1,3}))?[-. (]*(\\d{3})?[-. )]*(\\d{3})[-. ]*(\\d{4,5})(?: *x(\\d+))?'; const phoneRegex = new RegExp('\\s*' + regexBase + '\\s*', 'g');

this was to allow for things like dutch numbers, for example

+358 300 20200

For those having troubles while working with Anaconda3 (Python 3).

You could use

conda create -n name_of_your_virtualenv python=python_version 

To activate the environment ( Linux, MacOS)

source activate name_of_your_virtualenv

For Windows

activate name_of_your_virtualenv

This is the easiest way I found:

        BtnUpload.Style.Add("display", "none");
        FileUploader.Style.Add("display", "none");
        BtnAccept.Style.Add("display", "inherit");
        BtnClear.Style.Add("display", "inherit");

I have the opposite in the Else, so it handles displaying them as well. This can go in the Page's Load or in a method to refresh the controls on the page.

XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.

XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.

slice works just fine in IE and other browsers, it's part of the specification and it's the most efficient method too:

alert("xxx_456".slice(-3));
//-> 456

slice Method (String) - MSDN
slice - Mozilla Developer Center

In other thread I commented a solution for this issue in two ways:

First method:

func Find(slice interface{}, f func(value interface{}) bool) int {
    s := reflect.ValueOf(slice)
    if s.Kind() == reflect.Slice {
        for index := 0; index < s.Len(); index++ {
            if f(s.Index(index).Interface()) {
                return index
            }
        }
    }
    return -1
}

Use example:

type UserInfo struct {
    UserId          int
}

func main() {
    var (
        destinationList []UserInfo
        userId      int = 123
    )
    
    destinationList = append(destinationList, UserInfo { 
        UserId          : 23,
    }) 
    destinationList = append(destinationList, UserInfo { 
        UserId          : 12,
    }) 
    
    idx := Find(destinationList, func(value interface{}) bool {
        return value.(UserInfo).UserId == userId
    })
    
    if idx < 0 {
        fmt.Println("not found")
    } else {
        fmt.Println(idx)    
    }
}

Second method with less computational cost:

func Search(length int, f func(index int) bool) int {
    for index := 0; index < length; index++ {
        if f(index) {
            return index
        }
    }
    return -1
}

Use example:

type UserInfo struct {
    UserId          int
}

func main() {
    var (
        destinationList []UserInfo
        userId      int = 123
    )
    
    destinationList = append(destinationList, UserInfo { 
        UserId          : 23,
    }) 
    destinationList = append(destinationList, UserInfo { 
        UserId          : 123,
    }) 
    
    idx := Search(len(destinationList), func(index int) bool {
        return destinationList[index].UserId == userId
    })
    
    if  idx < 0 {
        fmt.Println("not found")
    } else {
        fmt.Println(idx)    
    }
}

$x is always a scalar. The hint is the sigil $: any variable (or dereferencing of some other type) starting with $ is a scalar. (See perldoc perldata for more about data types.)

A reference is just a particular type of scalar. The built-in function ref will tell you what kind of reference it is. On the other hand, if you have a blessed reference, ref will only tell you the package name the reference was blessed into, not the actual core type of the data (blessed references can be hashrefs, arrayrefs or other things). You can use Scalar::Util 's reftype will tell you what type of reference it is:

use Scalar::Util qw(reftype);

my $x = bless {}, 'My::Foo';
my $y = { };

print "type of x: " . ref($x) . "\n";
print "type of y: " . ref($y) . "\n";
print "base type of x: " . reftype($x) . "\n";
print "base type of y: " . reftype($y) . "\n";

...produces the output:

type of x: My::Foo
type of y: HASH
base type of x: HASH
base type of y: HASH

For more information about the other types of references (e.g. coderef, arrayref etc), see this question: How can I get Perl's ref() function to return REF, IO, and LVALUE? and perldoc perlref.

Note: You should not use ref to implement code branches with a blessed object (e.g. $ref($a) eq "My::Foo" ? say "is a Foo object" : say "foo not defined";) -- if you need to make any decisions based on the type of a variable, use isa (i.e if ($a->isa("My::Foo") { ... or if ($a->can("foo") { ...). Also see polymorphism.

Does it matter which is faster, if they don't do the same thing? Comparing the performance of statements with different meaning seems like a bad idea.

is tells you if the object implements ClassA anywhere in its type heirarchy. GetType() tells you about the most-derived type.

Not the same thing.

The other answers are not incorrect. However, now there are more options for opening files. For example, if you want the app to have long term, permanent acess to a file, you can use ACTION_OPEN_DOCUMENT instead. Refer to the official documentation: Open files using storage access framework. Also refer to this answer.

It took me a bit of scouting around to suss this out, but I've settled on this cross-browser implementation:

HTML

<div class="video" style="display: none">
    <div class="mask"></div>
    <a href="#" class="close-btn"><span class="fa fa-times"></span></a>
    <div class="overlay">
        <iframe id="player" width="100%" height="70%" src="//www.youtube.com/embed/Xp697DqsbUU" frameborder="0" allowfullscreen></iframe>
    </div>
</div>

jQuery

$('.launch-video').click(function() {
  $('.video').show();
  $("#player").attr('src','//www.youtube.com/embed/Xp697DqsbUU'); 
});

$('.close-btn').click(function() {
  $('.video').hide();
  $("#player").attr('src','');   
});

What it essentially does is open my lightbox and populate my src attribute, and on close, just remove the src value (then re-populates it on open).

I have another solution. I just want to test if executing a PowerShell script succeeds, because perhaps somebody might change the policy. As the argument, I just specify the path of the script to be executed.

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = @"powershell.exe";
startInfo.Arguments = @"& 'c:\Scripts\test.ps1'";
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();

string output = process.StandardOutput.ReadToEnd();
Assert.IsTrue(output.Contains("StringToBeVerifiedInAUnitTest"));

string errors = process.StandardError.ReadToEnd();
Assert.IsTrue(string.IsNullOrEmpty(errors));

With the contents of the script being:

$someVariable = "StringToBeVerifiedInAUnitTest"
$someVariable

The ISO file that suggested in the accepted answer is still not complete. The very complete offline installer is about 24GB! There is only one way to get it. follow these steps:

1. Download Web Installer from Microsoft Web Site
2. Execute the Installer. NOTE: the installer is still a simple downloader for the real web-installer.
3. After running the real web installer, Run Windows Task manager and find the real web installer path that is stored in your temp folder
4. copy the real installer somewhere else. like C:\VS Community\
5. Open Command Prompt and execute the installer that you copied to C:\VS Community\ with this argument: /Layout .
6. Now installer will download the FULL offline installer to your selected folder!

Good Luck

As of Java 8 you now can do it with a stream using a lambda:

list.stream().sorted(Comparator.comparing(customObject::getId))
             .foreach(object -> System.out.println(object));

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

You are trying to use the string as a function:

"Your new price is: $"(float(price) * 0.1)

Because there is nothing between the string literal and the (..) parenthesis, Python interprets that as an instruction to treat the string as a callable and invoke it with one argument:

>>> "Hello World!"(42)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object is not callable

Seems you forgot to concatenate (and call str()):

easygui.msgbox("Your new price is: $" + str(float(price) * 0.1))

The next line needs fixing as well:

easygui.msgbox("Your new price is: $" + str(float(price) * 0.2))

Alternatively, use string formatting with str.format():

easygui.msgbox("Your new price is: ${:.2f}".format(float(price) * 0.1))
easygui.msgbox("Your new price is: ${:.2f}".format(float(price) * 0.2))

where {:02.2f} will be replaced by your price calculation, formatting the floating point value as a value with 2 decimals.

Try this:

your_command 2>stderr.log 1>stdout.log

More information

The numerals 0 through 9 are file descriptors in bash. 0 stands for standard input, 1 stands for standard output, 2 stands for standard error. 3 through 9 are spare for any other temporary usage.

Any file descriptor can be redirected to a file or to another file descriptor using the operator >. You can instead use the operator >> to appends to a file instead of creating an empty one.

Usage:

file_descriptor > filename

file_descriptor > &file_descriptor

A simple solution that worked for me is to close the Terminal and restart it.

Working Solution in Java:

import java.awt.event.*;
import java.awt.Robot;

public class CircleMouse {

/* circle stuff */
final static int RADIUS = 100;
final static int XSTART = 500;
final static int YSTART = 500;
final static int DELAYMS = 1;
final static int ROUNDS = 5;

public static void main(String args[]) {

    long startT = System.currentTimeMillis();
    Robot bot = null;

    try {
        bot = new Robot();
    } catch (Exception failed) {
        System.err.println("Failed instantiating Robot: " + failed);
    }
    int mask = InputEvent.BUTTON1_DOWN_MASK;

    int howMany = 360 * ROUNDS;
    while (howMany > 0) {
        int x = getX(howMany);
        int y = getY(howMany);
        bot.mouseMove(x, y);
        bot.delay(DELAYMS);
        System.out.println("x:" + x + " y:" + y);
        howMany--;
    }

    long endT = System.currentTimeMillis();
    System.out.println("Duration: " + (endT - startT));

}

/**
 * 
 * @param angle
 *            in degree
 * @return
 */
private static int getX(int angle) {
    double radians = Math.toRadians(angle);
    Double x = RADIUS * Math.cos(radians) + XSTART;
    int result = x.intValue();

    return result;
}

/**
 * 
 * @param angle
 *            in degree
 * @return
 */
private static int getY(int angle) {
    double radians = Math.toRadians(angle);
    Double y = RADIUS * Math.sin(radians) + YSTART;
    int result = y.intValue();

    return result;
}
}

with open("filename.txt", "w+") as file:
  for line in file:
    print line

This with statement automatically opens and closes it for you and you can iterate over the lines of the file with a simple for loop

You can utilzed the special function for activating the navigation for your programming purpose. Below is the sample code for it.

   void Specialkey(int key, int x, int y)
    {
    switch(key)
    {
    case GLUT_KEY_UP: 
/*Do whatever you want*/        
         break; 
    case GLUT_KEY_DOWN: 
/*Do whatever you want*/
                 break;
    case GLUT_KEY_LEFT:
/*Do whatever you want*/
                 break;
    case GLUT_KEY_RIGHT:
/*Do whatever you want*/
                 break;
    }

    glutPostRedisplay();
    }

Add this to your main function

glutSpecialFunc(Specialkey);

Hope this will to solve the problem!

2. change the lines and find your commit that the wrong file sent as commit

3. you can see the list of your changes in that commit
4. select it and then click on ... buttons right-hand side ... click reverse file
5. then you can see it on file status tab at the bottom left-hand side then click unstage:

6. open your visual studio code and revert back by committing your removed files
7. after them all, you can see results in your last commit in the source tree

if you have a list a and then following statements

list<int>::iterator it; // declare an iterator
    list<int>::const_iterator cit; // declare an const iterator 
    it=a.begin();
    cit=a.begin();

you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.

*it=*it+1;//returns no error
    *cit=*cit+1;//this will return error

In Internet Explorer, there must be declared a <!DOCTYPE> for the :hover selector to work on other elements than the <a> element.

If you are using java-8 there's also another way to do this.

int[] arr = list.stream().mapToInt(i -> i).toArray();

What it does is:

• getting a Stream<Integer> from the list
• obtaining an IntStream by mapping each element to itself (identity function), unboxing the int value hold by each Integer object (done automatically since Java 5)
• getting the array of int by calling toArray

You could also explicitly call intValue via a method reference, i.e:

int[] arr = list.stream().mapToInt(Integer::intValue).toArray();

It's also worth mentioning that you could get a NullPointerException if you have any null reference in the list. This could be easily avoided by adding a filtering condition to the stream pipeline like this:

                       //.filter(Objects::nonNull) also works
int[] arr = list.stream().filter(i -> i != null).mapToInt(i -> i).toArray();

Example:

List<Integer> list = Arrays.asList(1, 2, 3, 4);
int[] arr = list.stream().mapToInt(i -> i).toArray(); //[1, 2, 3, 4]

list.set(1, null); //[1, null, 3, 4]
arr = list.stream().filter(i -> i != null).mapToInt(i -> i).toArray(); //[1, 3, 4]

Your script is blocked from executing due to the execution policy.

You need to run PowerShell as administrator and set it on the client PC to Unrestricted. You can do that by calling Invoke with:

The diffrence is very simple:

Long version

If you want to have better readability, use Math.floor. But if you want to minimize it, use tilde ~~.

There are a lot of sources on the internet saying Math.floor is faster, but sometimes ~~. I would not recommend you think about speed because it is not going to be noticed when running the code. Maybe in tests etc, but no human can see a diffrence here. What would be faster is to use ~~ for a faster load time.

Short version

~~ is shorter/takes less space. Math.floor improves the readability. Sometimes tilde is faster, sometimes Math.floor is faster, but it is not noticeable.

This problem has just happened to me and has been solved simply by increasing memory_limit from 32 M to 64 M You can adjust the value on the file where php.ini exists

locate php.ini then choose the right file and search for memory_limit and after modifying it you must reboot the apache /etc/init.d/httpd restart

All the best.

Just (array) is missing in your code before the simplexml object:

...

$xml   = simplexml_load_string($string, 'SimpleXMLElement', LIBXML_NOCDATA);

$array = json_decode(json_encode((array)$xml), TRUE);
                                 ^^^^^^^

Just to complete Amit Garg answer, there are several ways to inject dependencies in AngularJS.

You can also use $inject to add a dependency:

var MyController = function($scope, $http) {
  // ...
}
MyController.$inject = ['$scope', '$http'];

For Chrome Version 52.0.2743.116:

1. In Chrome's Developer Tools, bring up the 'Search' panel by hitting Ctrl+Shift+F.

2. Type in the name of the element you're trying to find.

Results for binded elements should appear in the panel and state the file they're located in.

Here is how I did it in AngularJS

app = angular.module('MM_Graph')

class Keyboard
  constructor: ($injector)->
    @.$injector  = $injector
    @.$window    = @.$injector.get('$window')                             # get reference to $window and $rootScope objects
    @.$rootScope = @.$injector.get('$rootScope')

  on_Key_Down:($event)=>
    @.$rootScope.$broadcast 'keydown', $event                             # broadcast a global keydown event

    if $event.code is 'KeyS' and ($event.ctrlKey or $event.metaKey)       # detect S key pressed and either OSX Command or Window's Control keys pressed
      @.$rootScope.$broadcast '', $event                                  # broadcast keyup_CtrS event
      #$event.preventDefault()                                             # this should be used by the event listeners to prevent default browser behaviour

  setup_Hooks: ()=>
    angular.element(@.$window).bind "keydown", @.on_Key_Down              # hook keydown event in window (only called once per app load)
    @

app.service 'keyboard', ($injector)=>
  return new Keyboard($injector).setup_Hooks()

Starting with:

houses <- read.table(text="Semi            1
Single          2
Row             3
Single          2
Apartment       4
Apartment       4
Row             3",col.names=c("HouseType","HouseTypeNo"))

... you can use

as.numeric(factor(houses$HouseType))

... to give a unique number for each house type. You can see the result here:

> houses2 <- data.frame(houses,as.numeric(factor(houses$HouseType)))
> houses2
  HouseType HouseTypeNo as.numeric.factor.houses.HouseType..
1      Semi           1                                    3
2    Single           2                                    4
3       Row           3                                    2
4    Single           2                                    4
5 Apartment           4                                    1
6 Apartment           4                                    1
7       Row           3                                    2

... so you end up with different numbers on the rows (because the factors are ordered alphabetically) but the same pattern.

(EDIT: the remaining text in this answer is actually redundant. It occurred to me to check and it turned out that read.table() had already made houses$HouseType into a factor when it was read into the dataframe in the first place).

However, you may well be better just to convert HouseType to a factor, which would give you all the same benefits as HouseTypeNo, but would be easier to interpret because the house types are named rather than numbered, e.g.:

> houses3 <- houses
> houses3$HouseType <- factor(houses3$HouseType)
> houses3
  HouseType HouseTypeNo
1      Semi           1
2    Single           2
3       Row           3
4    Single           2
5 Apartment           4
6 Apartment           4
7       Row           3
> levels(houses3$HouseType)
[1] "Apartment" "Row"       "Semi"      "Single"  

Just do this:

// ****** Every first letter capital in word *********
<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textCapWords"
    />

//***** if all letters are capital ************

    android:inputType="textCapCharacters"

To get reference to UIViewController having UIView, you could make extension of UIResponder (which is super class for UIView and UIViewController), which allows to go up through the responder chain and thus reaching UIViewController (otherwise returning nil).

extension UIResponder {
    func getParentViewController() -> UIViewController? {
        if self.nextResponder() is UIViewController {
            return self.nextResponder() as? UIViewController
        } else {
            if self.nextResponder() != nil {
                return (self.nextResponder()!).getParentViewController()
            }
            else {return nil}
        }
    }
}

//Swift 3
extension UIResponder {
    func getParentViewController() -> UIViewController? {
        if self.next is UIViewController {
            return self.next as? UIViewController
        } else {
            if self.next != nil {
                return (self.next!).getParentViewController()
            }
            else {return nil}
        }
    }
}

let vc = UIViewController()
let view = UIView()
vc.view.addSubview(view)
view.getParentViewController() //provide reference to vc

Don't forget to return the mapped array , like:

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })

}

Reference for the map() method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

You can define assertNotRaises by reusing about 90% of the original implementation of assertRaises in the unittest module. With this approach, you end up with an assertNotRaises method that, aside from its reversed failure condition, behaves identically to assertRaises.

TLDR and live demo

It turns out to be surprisingly easy to add an assertNotRaises method to unittest.TestCase (it took me about 4 times as long to write this answer as it did the code). Here's a live demo of the assertNotRaises method in action. Just like assertRaises, you can either pass a callable and args to assertNotRaises, or you can use it in a with statement. The live demo includes a test cases that demonstrates that assertNotRaises works as intended.

Details

The implementation of assertRaises in unittest is fairly complicated, but with a little bit of clever subclassing you can override and reverse its failure condition.

assertRaises is a short method that basically just creates an instance of the unittest.case._AssertRaisesContext class and returns it (see its definition in the unittest.case module). You can define your own _AssertNotRaisesContext class by subclassing _AssertRaisesContext and overriding its __exit__ method:

import traceback
from unittest.case import _AssertRaisesContext

class _AssertNotRaisesContext(_AssertRaisesContext):
    def __exit__(self, exc_type, exc_value, tb):
        if exc_type is not None:
            self.exception = exc_value.with_traceback(None)

            try:
                exc_name = self.expected.__name__
            except AttributeError:
                exc_name = str(self.expected)

            if self.obj_name:
                self._raiseFailure("{} raised by {}".format(exc_name,
                    self.obj_name))
            else:
                self._raiseFailure("{} raised".format(exc_name))

        else:
            traceback.clear_frames(tb)

        return True

Normally you define test case classes by having them inherit from TestCase. If you instead inherit from a subclass MyTestCase:

class MyTestCase(unittest.TestCase):
    def assertNotRaises(self, expected_exception, *args, **kwargs):
        context = _AssertNotRaisesContext(expected_exception, self)
        try:
            return context.handle('assertNotRaises', args, kwargs)
        finally:
            context = None

all of your test cases will now have the assertNotRaises method available to them.

The parent component can manage child state passing a prop to child and the child convert this prop in state using componentWillReceiveProps.

class ParentComponent extends Component {
  state = { drawerOpen: false }
  toggleChildMenu = () => {
    this.setState({ drawerOpen: !this.state.drawerOpen })
  }
  render() {
    return (
      <div>
        <button onClick={this.toggleChildMenu}>Toggle Menu from Parent</button>
        <ChildComponent drawerOpen={this.state.drawerOpen} />
      </div>
    )
  }
}

class ChildComponent extends Component {
  constructor(props) {
    super(props)
    this.state = {
      open: false
    }
  }

  componentWillReceiveProps(props) {
    this.setState({ open: props.drawerOpen })
  }

  toggleMenu() {
    this.setState({
      open: !this.state.open
    })
  }

  render() {
    return <Drawer open={this.state.open} />
  }
}

Because they override the browser default, the select styling needs Javascript to run. You need to include the Materialize Javascript file, and then call

$(document).ready(function() {
    $('select').formSelect();
    // Old way
    // $('select').material_select();
});

after you've loaded that file.

Yes, thats right.

You can get an idea by the usage of these two.

If you need to tell that you are finished with some work and other (threads) waiting for this can now proceed, you should use ManualResetEvent.

If you need to have mutual exclusive access to any resource, you should use AutoResetEvent.

Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.

         varLines = Split(.responsetext, """,""")
        strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)

The error means that the Postgres server is not running. Try starting it:

sudo systemctl start postgresql

Make sure that the server starts on boot:

sudo systemctl enable postgresql

Problem:

error Property 'text' does not exist on type 'HTMLElement'

Solution: in typeScript we need to cast document.getElementById() which returns type HTMLElement in < HTMLScriptElement >

So we can do it by by following way to resolve the error as expected by typescript.js

Code: var content: string = ( < HTMLScriptElement > document.getElementById(contentId)).text;

It worked for me.. hope it works for you as well.

Grand Performance Comparison

^{Scroll to the end for a TL;DR graph}

Since I had "nothing better to do" (understand: I had just a lot of work), I decided to do a little performance contest. I assembled the most sensible or interesting answers and did some simple timeit in CPython 3.5.1 on them. I tested them with only one string, which is a typical input in my case:

>>> s = 'ZDXMZKMXFDKXZFKZ'
>>> len(s)
16

Be aware that results might vary for different inputs, be it different length of the string or different number of distinct characters, or different average number of occurrences per character.

Don't reinvent the wheel

Python has made it simple for us. The collections.Counter class does exactly what we want and a lot more. Its usage is by far the simplest of all the methods mentioned here.

taken from @oefe, nice find

>>> timeit('Counter(s)', globals=locals())
8.208566107001388

Counter goes the extra mile, which is why it takes so long.

¿Dictionary, comprende?

Let's try using a simple dict instead. First, let's do it declaratively, using dict comprehension.

I came up with this myself...

>>> timeit('{c: s.count(c) for c in s}', globals=locals())
4.551155784000002

This will go through s from beginning to end, and for each character it will count the number of its occurrences in s. Since s contains duplicate characters, the above method searches s several times for the same character. The result is naturally always the same. So let's count the number of occurrences just once for each character.

I came up with this myself, and so did @IrshadBhat

>>> timeit('{c: s.count(c) for c in set(s)}', globals=locals())
3.1484066140001232

Better. But we still have to search through the string to count the occurrences. One search for each distinct character. That means we're going to read the string more than once. We can do better than that! But for that, we have to get off our declarativist high horse and descend into an imperative mindset.

Exceptional code

AKA Gotta catch 'em all!

inspired by @anthony

>>> timeit('''
... d = {}
... for c in s:
...   try:
...     d[c] += 1
...   except KeyError:
...     d[c] = 1
... ''', globals=locals())
3.7060273620008957

Well, it was worth a try. If you dig into the Python source (I can't say with certainty because I have never really done that), you will probably find that when you do except ExceptionType, Python has to check whether the exception raised is actually of ExceptionType or some other type. Just for the heck of it, let's see how long will it take if we omit that check and catch all exceptions.

made by @anthony

>>> timeit('''
... d = {}
... for c in s:
...   try:
...     d[c] += 1
...   except:
...     d[c] = 1
... ''', globals=locals())
3.3506563019982423

It does save some time, so one might be tempted to use this as some sort of optimization.
Don't do that! Or actually do. Do it now:

_{INTERLUDE 1}

import time
while True:
  try:
    time.sleep(1)
  except:
    print("You're trapped in your own trap!")

You see? It catches KeyboardInterrupt, besides other things. In fact, it catches all the exceptions there are. Including ones you might not have even heard about, like SystemExit.

_{INTERLUDE 2}

import sys
try:
  print("Goodbye. I'm going to die soon.")
  sys.exit()
except:
  print('BACK FROM THE DEAD!!!')

Now back to counting letters and numbers and other characters.

Playing catch-up

Exceptions aren't the way to go. You have to try hard to catch up with them, and when you finally do, they just throw up on you and then raise their eyebrows like it's your fault. Luckily brave fellows have paved our way so we can do away with exceptions, at least in this little exercise.

The dict class has a nice method – get – which allows us to retrieve an item from a dictionary, just like d[k]. Except when the key k is not in the dictionary, it can return a default value. Let's use that method instead of fiddling with exceptions.

credit goes to @Usman

>>> timeit('''
... d = {}
... for c in s:
...   d[c] = d.get(c, 0) + 1
... ''', globals=locals())
3.2133633289995487

Almost as fast as the set-based dict comprehension. On larger inputs, this one would probably be even faster.

Use the right tool for the job

For at least mildly knowledgeable Python programmer, the first thing that comes to mind is probably defaultdict. It does pretty much the same thing as the version above, except instead of a value, you give it a value factory. That might cause some overhead, because the value has to be "constructed" for each missing key individually. Let's see how it performs.

hope @AlexMartelli won't crucify me for from collections import defaultdict

>>> timeit('''
... dd = defaultdict(int)
... for c in s:
...   dd[c] += 1
... ''', globals=locals())
3.3430528169992613

Not that bad. I'd say the increase in execution time is a small tax to pay for the improved readability. However, we also favor performance, and we will not stop here. Let's take it further and prepopulate the dictionary with zeros. Then we won't have to check every time if the item is already there.

hats off to @sqram

>>> timeit('''
... d = dict.fromkeys(s, 0)
... for c in s:
...   d[c] += 1
... ''', globals=locals())
2.6081761489986093

That's good. Over three times as fast as Counter, yet still simple enough. Personally, this is my favorite in case you don't want to add new characters later. And even if you do, you can still do it. It's just less convenient than it would be in other versions:

d.update({ c: 0 for c in set(other_string) - d.keys() })

Practicality beats purity (except when it's not really practical)

Now a bit different kind of counter. @IdanK has come up with something interesting. Instead of using a hash table (a.k.a. dictionary a.k.a. dict), we can avoid the risk of hash collisions and consequent overhead of their resolution. We can also avoid the overhead of hashing the key, and the extra unoccupied table space. We can use a list. The ASCII values of characters will be indices and their counts will be values. As @IdanK has pointed out, this list gives us constant time access to a character's count. All we have to do is convert each character from str to int using the built-in function ord. That will give us an index into the list, which we will then use to increment the count of the character. So what we do is this: we initialize the list with zeros, do the job, and then convert the list into a dict. This dict will only contain those characters which have non-zero counts, in order to make it compliant with other versions.

As a side note, this technique is used in a linear-time sorting algorithm known as count sort or counting sort. It's very efficient, but the range of values being sorted is limited, since each value has to have its own counter. To sort a sequence of 32-bit integers, 4.3 billion counters would be needed.

>>> timeit('''
... counts = [0 for _ in range(256)]
... for c in s:
...   counts[ord(c)] += 1
... d = {chr(i): count for i,count in enumerate(counts) if count != 0}
... ''', globals=locals())
25.438595562001865

Ouch! Not cool! Let's try and see how long it takes when we omit building the dictionary.

>>> timeit('''
... counts = [0 for _ in range(256)]
... for c in s:
...   counts[ord(c)] += 1
... ''', globals=locals())
10.564866792999965

Still bad. But wait, what's [0 for _ in range(256)]? Can't we write it more simply? How about [0] * 256? That's cleaner. But will it perform better?

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... ''', globals=locals())
3.290163638001104

Considerably. Now let's put the dictionary back in.

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... d = {chr(i): count for i,count in enumerate(counts) if count != 0}
... ''', globals=locals())
18.000623562998953

Almost six times slower. Why does it take so long? Because when we enumerate(counts), we have to check every one of the 256 counts and see if it's zero. But we already know which counts are zero and which are not.

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... d = {c: counts[ord(c)] for c in set(s)}
... ''', globals=locals())
5.826531438000529

It probably won't get much better than that, at least not for such a small input. Plus it's only usable for 8-bit EASCII characters. ? ?????!

And the winner is...

>>> timeit('''
... d = {}
... for c in s:
...   if c in d:
...     d[c] += 1
...   else:
...     d[c] = 1
... ''', globals=locals())
1.8509794599995075

Yep. Even if you have to check every time whether c is in d, for this input it's the fastest way. No pre-population of d will make it faster (again, for this input). It's a lot more verbose than Counter or defaultdict, but also more efficient.

That's all folks

This little exercise teaches us a lesson: when optimizing, always measure performance, ideally with your expected inputs. Optimize for the common case. Don't presume something is actually more efficient just because its asymptotic complexity is lower. And last but not least, keep readability in mind. Try to find a compromise between "computer-friendly" and "human-friendly".

UPDATE

I have been informed by @MartijnPieters of the function collections._count_elements available in Python 3.

Help on built-in function _count_elements in module _collections:

_count_elements(...)
    _count_elements(mapping, iterable) -> None

    Count elements in the iterable, updating the mappping

This function is implemented in C, so it should be faster, but this extra performance comes at a price. The price is incompatibility with Python 2 and possibly even future versions, since we're using a private function.

From the documentation:

[...] a name prefixed with an underscore (e.g. _spam) should be treated as a non-public part of the API (whether it is a function, a method or a data member). It should be considered an implementation detail and subject to change without notice.

That said, if you still want to save those 620 nanoseconds per iteration:

>>> timeit('''
... d = {}
... _count_elements(d, s)
... ''', globals=locals())
1.229239897998923

UPDATE 2: Large strings

I thought it might be a good idea to re-run the tests on some larger input, since a 16 character string is such a small input that all the possible solutions were quite comparably fast (1,000 iterations in under 30 milliseconds).

I decided to use the complete works of Shakespeare as a testing corpus, which turned out to be quite a challenge (since it's over 5MiB in size ). I just used the first 100,000 characters of it, and I had to limit the number of iterations from 1,000,000 to 1,000.

import urllib.request
url = 'https://ocw.mit.edu/ans7870/6/6.006/s08/lecturenotes/files/t8.shakespeare.txt'
s = urllib.request.urlopen(url).read(100_000)

collections.Counter was really slow on a small input, but the tables have turned

Counter(s)

=> 7.63926783799991

Naïve T(n²) time dictionary comprehension simply doesn't work

{c: s.count(c) for c in s}

=> 15347.603935000052s (tested on 10 iterations; adjusted for 1000)

Smart T(n) time dictionary comprehension works fine

{c: s.count(c) for c in set(s)}

=> 8.882608592999986

Exceptions are clumsy and slow

d = {}
for c in s:
  try:
    d[c] += 1
  except KeyError:
    d[c] = 1

=> 21.26615508399982

Omitting the exception type check doesn't save time (since the exception is only thrown a few times)

d = {}
for c in s:
  try:
    d[c] += 1
  except:
    d[c] = 1

=> 21.943328911999743

dict.get looks nice but runs slow

d = {}
for c in s:
  d[c] = d.get(c, 0) + 1

=> 28.530086210000007

collections.defaultdict isn't very fast either

dd = defaultdict(int)
for c in s:
  dd[c] += 1

=> 19.43012963199999

dict.fromkeys requires reading the (very long) string twice

d = dict.fromkeys(s, 0)
for c in s:
  d[c] += 1

=> 22.70960557699999

Using list instead of dict is neither nice nor fast

counts = [0 for _ in range(256)]
for c in s:
  counts[ord(c)] += 1

d = {chr(i): count for i,count in enumerate(counts) if count != 0}

=> 26.535474792000002

Leaving out the final conversion to dict doesn't help

counts = [0 for _ in range(256)]
for c in s:
  counts[ord(c)] += 1

=> 26.27811567400005

It doesn't matter how you construct the list, since it's not the bottleneck

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

=> 25.863524940000048

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

d = {chr(i): count for i,count in enumerate(counts) if count != 0}

=> 26.416733378000004

If you convert list to dict the "smart" way, it's even slower (since you iterate over the string twice)

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

d = {c: counts[ord(c)] for c in set(s)}

=> 29.492915620000076

The dict.__contains__ variant may be fast for small strings, but not so much for big ones

d = {}
for c in s:
  if c in d:
    d[c] += 1
  else:
    d[c] = 1

=> 23.773295123000025

collections._count_elements is about as fast as collections.Counter (which uses _count_elements internally)

d = {}
_count_elements(d, s)

=> 7.5814381919999505

Final verdict: Use collections.Counter unless you cannot or don't want to :)

Appendix: NumPy

The numpy package provides a method numpy.unique which accomplishes (almost) precisely what we want.

The way this method works is very different from all the above methods:

• It first sorts a copy of the input using Quicksort, which is an O(n²) time operation in the worst case, albeit O(n log n) on average and O(n) in the best case.

• Then it creates a "mask" array containing True at indices where a run of the same values begins, viz. at indices where the value differs from the previous value. Repeated values produce False in the mask. Example: [5,5,5,8,9,9] produces a mask [True, False, False, True, True, False].

• This mask is then used to extract the unique values from the sorted input - unique_chars in the code below. In our example, they would be [5, 8, 9].

• Positions of the True values in the mask are taken into an array, and the length of the input is appended at the end of this array. For the above example, this array would be [0, 3, 4, 6].

• For this array, differences between its elements are calculated, eg. [3, 1, 2]. These are the respective counts of the elements in the sorted array - char_counts in the code below.

• Finally, we create a dictionary by zipping unique_chars and char_counts: {5: 3, 8: 1, 9: 2}.

import numpy as np

def count_chars(s):
  # The following statement needs to be changed for different input types.
  # Our input `s` is actually of type `bytes`, so we use `np.frombuffer`.
  # For inputs of type `str`, change `np.frombuffer` to `np.fromstring`
  #  or transform the input into a `bytes` instance.
  arr = np.frombuffer(s, dtype=np.uint8)

  unique_chars, char_counts = np.unique(arr, return_counts=True)

  return dict(zip(unique_chars, char_counts))

For the test input (first 100,000 characters of the complete works of Shakespeare), this method performs better than any other tested here. But note that on a different input, this approach might yield worse performance than the other methods. Pre-sortedness of the input and number of repetitions per element are important factors affecting the performance.

count_chars(s)

=> 2.960809530000006

If you are thinking about using this method because it's over twice as fast as collections.Counter, consider this:

• collections.Counter has linear time complexity. numpy.unique is linear at best, quadratic at worst.

• The speedup is not really that significant - you save ~3.5 milliseconds per iteration on an input of length 100,000.

• Using numpy.unique obviously requires numpy.

That considered, it seems reasonable to use Counter unless you need to be really fast. And in that case, you better know what you're doing or else you'll end up being slower with numpy than without it.

Appendix 2: A somewhat useful plot

I ran the 13 different methods above on prefixes of the complete works of Shakespeare and made an interactive plot. Note that in the plot, both prefixes and durations are displayed in logarithmic scale (the used prefixes are of exponentially increasing length). Click on the items in the legend to show/hide them in the plot.

I know this is not the solution to OPs post. However, this post is the first one indexed by Google when I searched for answers to this error. For this reason I feel this will benefit others.

The following error...

The POST method is not supported for this route. Supported methods: GET, HEAD.

The Basics

Look at these to build a solution more or less from scratch:

• Start from the basics: The Java Tutorial's chapter on Networking, including Working With URLs
• Make things easier for yourself: Apache HttpComponents (including HttpClient)

The Easily Glued-Up and Stitched-Up Stuff

You always have the option of calling external tools from Java using the exec() and similar methods. For instance, you could use wget, or cURL.

The Hardcore Stuff

Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:

• HtmlUnit (powerful and simple)
• Selenium, Selenium-RC
• WebDriver/Selenium2 (still in the works)
• JBehave with JBehave Web

Some other libs are purposefully written with web-scraping in mind:

• JSoup
• Jaunt

Some Workarounds

Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.

Check out:

• Groovy (and its XmlSlurper)
• or Scala (with great XML support as presented here and here)

If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.

Some Supplements

Some other similar questions:

• Scrape data from HTML using Java
• Options for HTML Scraping

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

I ran into this issue and found that mysqlclient needs to know where to find openssl, and OSX hides this by default.

Locate openssl with brew info openssl, and then add the path to your openssl bin to your PATH:

export PATH="/usr/local/opt/openssl/bin:$PATH"

I recommend adding that to your .zshrc or .bashrc so you don't need to worry about it in the future. Then, with that variable exported (which may meed closing and re-opening your bash session), add two more env variables:

# in terminal
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

Then, finally, run:

pipenv install mysqlclient

and it should install just fine.

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

Not to be vague or anything but I think the type of 'file' you will be storing is one of the biggest determining factors. If you essentially talking about a large text field which could be stored as file my preference would be for db storage.

Yes, we can check this.

Input

print_lyrics() 
def print_lyrics():

    print("I'm a lumberjack, and I'm okay.")
    print("I sleep all night and I work all day.")

def repeat_lyrics():
    print_lyrics()
    print_lyrics()
repeat_lyrics()

Output

I'm a lumberjack, and I'm okay.
I sleep all night and I work all day.
I'm a lumberjack, and I'm okay.
I sleep all night and I work all day.
I'm a lumberjack, and I'm okay.
I sleep all night and I work all day.

As BJ Homer mentioned over above comments, A general rule in Python is not that function should be defined higher in the code (as in Pascal), but that it should be defined before its usage.

Hope that helps.

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 use the String.format() method.

Method 1:

If the method DoSomethingBeta was static you need only call:

Beta.DoSomethingBeta();

Method 2:

If Alpha extends from Beta you could call DoSomethingBeta() directly.

public class Alpha extends Beta{
     public void DoSomethingAlpha() {
          DoSomethingBeta();  //?
     }
}

Method 3:

Alternatively you need to have access to an instance of Beta to call the methods from it.

public class Alpha {
     public void DoSomethingAlpha() {
          Beta cbeta = new Beta();
          cbeta.DoSomethingBeta();  //?
     }
}

Incidentally is this homework?

# cat .bash_profile | grep PATH
PATH=$HOME/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin
export PATH

# cat /etc/sudoers | grep Defaults
Defaults    requiretty
Defaults    env_reset
Defaults    env_keep = "SOME_PARAM1 SOME_PARAM2 ... PATH"

You access the property in the wrong way. With the $this->$my_value = .. syntax, you set the property with the name of the value in $my_value. What you want is $this->my_value = ..

$var = "my_value";
$this->$var = "test";

is the same as

$this->my_value = "test";

To fix a few things from your example, the code below is a better aproach

class my_class {

    public  $my_value = array();

    function __construct ($value) {
        $this->my_value[] = $value;
    }

    function set_value ($value) {
        if (!is_array($value)) {
            throw new Exception("Illegal argument");
        }

        $this->my_value = $value;
    }

    function add_value($value) {
        $this->my_value = $value;
    }
}

$a = new my_class ('a');
$a->my_value[] = 'b';
$a->add_value('c');
$a->set_value(array('d'));

This ensures, that my_value won't change it's type to string or something else when you call set_value. But you can still set the value of my_value direct, because it's public. The final step is, to make my_value private and only access my_value over getter/setter methods

$("#Id").change(function(){
    var selected = $('#Id option:selected').val();
    alert(selected);           
});

I think this is what you need.

No, it's not POSIX behaviour, it's ISO behaviour (well, it is POSIX behaviour but only insofar as they conform to ISO).

Standard output is line buffered if it can be detected to refer to an interactive device, otherwise it's fully buffered. So there are situations where printf won't flush, even if it gets a newline to send out, such as:

myprog >myfile.txt

This makes sense for efficiency since, if you're interacting with a user, they probably want to see every line. If you're sending the output to a file, it's most likely that there's not a user at the other end (though not impossible, they could be tailing the file). Now you could argue that the user wants to see every character but there are two problems with that.

The first is that it's not very efficient. The second is that the original ANSI C mandate was to primarily codify existing behaviour, rather than invent new behaviour, and those design decisions were made long before ANSI started the process. Even ISO nowadays treads very carefully when changing existing rules in the standards.

As to how to deal with that, if you fflush (stdout) after every output call that you want to see immediately, that will solve the problem.

Alternatively, you can use setvbuf before operating on stdout, to set it to unbuffered and you won't have to worry about adding all those fflush lines to your code:

setvbuf (stdout, NULL, _IONBF, BUFSIZ);

Just keep in mind that may affect performance quite a bit if you are sending the output to a file. Also keep in mind that support for this is implementation-defined, not guaranteed by the standard.

ISO C99 section 7.19.3/3 is the relevant bit:

When a stream is unbuffered, characters are intended to appear from the source or at the destination as soon as possible. Otherwise characters may be accumulated and transmitted to or from the host environment as a block.

When a stream is fully buffered, characters are intended to be transmitted to or from the host environment as a block when a buffer is filled.

When a stream is line buffered, characters are intended to be transmitted to or from the host environment as a block when a new-line character is encountered.

Furthermore, characters are intended to be transmitted as a block to the host environment when a buffer is filled, when input is requested on an unbuffered stream, or when input is requested on a line buffered stream that requires the transmission of characters from the host environment.

Support for these characteristics is implementation-defined, and may be affected via the setbuf and setvbuf functions.

You can use .substring, which returns a potion of a string:

"abcdefghijklmnopq".substring(0, 8) === "abcdefgh"; // portion from index 0 to 8

I had this error too, I changed the code like this then it worked.

html

 <html ng-app="app">

   <div ng-controller="firstCtrl">
       ...
   </div>

 </html>

app.js

(function(){

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

    app.controller('firstCtrl',function($scope){    
         ...
    })

})();

You have to make sure that the name in module is same as ng-app

then div will be in the scope of firstCtrl

Try this :

width:auto;
margin-right:50px;

You can add a class to each of your .row divs to add some space in between them like so:

.spacer {
    margin-top: 40px; /* define margin as you see fit */
}

You can then use it like so:

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

find already looks recursively by default:

[15:21:53 ~]$ mkdir foo
[15:22:28 ~]$ cd foo
[15:22:31 ~/foo]$ mkdir bar
[15:22:35 ~/foo]$ cd bar
[15:22:36 ~/foo/bar]$ ln -s ../foo abc
[15:22:40 ~/foo/bar]$ cd ..
[15:22:47 ~/foo]$ ln -s foo abc
[15:22:52 ~/foo]$ find ./ -type l
.//abc
.//bar/abc
[15:22:57 ~/foo]$ 

Or you can just use this method in case you don't have StringUtils on hand:

public static String abbreviateString(String input, int maxLength) {
    if (input.length() <= maxLength) 
        return input;
    else 
        return input.substring(0, maxLength-2) + "..";
}

Alt+H, then type letters FC, then pick the color.

I've used this function to merge objects in the past, I use it to add or update existing properties on obj1 with values from obj2:

var _mergeRecursive = function(obj1, obj2) {

      //iterate over all the properties in the object which is being consumed
      for (var p in obj2) {
          // Property in destination object set; update its value.
          if ( obj2.hasOwnProperty(p) && typeof obj1[p] !== "undefined" ) {
            _mergeRecursive(obj1[p], obj2[p]);

          } else {
            //We don't have that level in the heirarchy so add it
            obj1[p] = obj2[p];

          }
     }
}

It will handle multiple levels of hierarchy as well as single level objects. I used it as part of a utility library for manipulating JSON objects. You can find it here.

The java.lang.OutOfMemoryError: PermGen space message indicates that the Permanent Generation’s area in memory is exhausted.

Any Java applications is allowed to use a limited amount of memory. The exact amount of memory your particular application can use is specified during application startup.

Java memory is separated into different regions which can be seen in the following image:

Metaspace: A new memory space is born

The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace; similar to the Oracle JRockit and IBM JVM's.

The good news is that it means no more java.lang.OutOfMemoryError: PermGen space problems and no need for you to tune and monitor this memory space anymore using Java_8_Download or higher.

An easier tool to monitor the tracking tags is to use the Chrome extension (probably available, or the equivalent for other browsers) - Google Tag Assistant. This will show what tags are firing, what problems it has found, and even breaks out stuff like eCommerce values for easy reading. Also works with the Google Tag Manager, and can handle multiple sets of tags on the page.

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

I see that this problem was discussed some time ago, but if anyone 'll meet with this again, here is my solution:

In your *.cshtml View file:

<script>
var data = JsFunction("@Html.Raw(Model.Path)");
$(function () {
    $("#btn").click(function () {
        var model = { Id: '@Html.Raw(Model.Id)', Data: data }
        $.ajax({
            type: "POST",
            url: "/Controller/Action",
            data: model,
            datatype: "html",
            success: function() {
                console.log('Success');
            }
        });
    });
});
</script>

JavaScript variable model is something that I need to pass to Razor ViewModel. It can be done with ajax request. You just need to have proper argument/s in your action, that matches Json object created in JavaScript.

Hope it'll help someone!

For IIS 8 There is a extra step to do other than changing the customErrors=Off to show the error content.

<system.web>
   <customErrors mode="Off" />
</system.web>
<system.webServer>
   <httpErrors existingResponse="PassThrough" errorMode="Detailed"/>
</system.webServer>

Raul answered the question in this link Turn off IIS8 custom errors by Raul

allocationSize=1 It is a micro optimization before getting query Hibernate tries to assign value in the range of allocationSize and so try to avoid querying database for sequence. But this query will be executed every time if you set it to 1. This hardly makes any difference since if your data base is accessed by some other application then it will create issues if same id is used by another application meantime .

Next generation of Sequence Id is based on allocationSize.

By defualt it is kept as 50 which is too much. It will also only help if your going to have near about 50 records in one session which are not persisted and which will be persisted using this particular session and transation.

So you should always use allocationSize=1 while using SequenceGenerator. As for most of underlying databases sequence is always incremented by 1.

I am now running OS Big Sur. xcode-select --install, and sudo xcode-select --reset did not resolve my issue, neither did the recommended subsequent softwareupdate --install -a command. For good measure, I tried the recommended download from Apple Downloads, but the Command Line Tools downloads available there are not compatible with my OS.

I upvoted the fix that resolved for me, sudo xcode-select --switch /Library/Developer/CommandLineTools/ and added this post for environment context.

You can use the following mapper configuration:

mapper.getSerializationConfig().setSerializationInclusion(Inclusion.NON_NULL);

Since 2.5 you can user:

mapper.setSerializationInclusion(Include.NON_NULL);

Did the same thing. Wasn't able to recreate Default Web Site directly - it kept complaining that the file already existed...

I fixed as follows:

1. Create a new web site called something else, eg. "Default", pointing to "C:\inetpub\wwwroot"
2. It should be created with ID 1 (at least mine was)
3. Rename the web site to "Default Web Site"

You need a bindingsource object to act as an intermediary and assist in the binding. Then instead of updating the user interface, update the underlining model.

var model = (Fruit) bindingSource1.DataSource;

model.FruitType = "oranges";

bindingSource.ResetBindings();

Read up on BindingSource and simple data binding for Windows Forms.

Another way to get a subset of columns from your DataFrame, assuming you want all the rows, would be to do:
data[['a','b']] and data[['c','d','e']]
If you want to use numerical column indexes you can do:
data[data.columns[:2]] and data[data.columns[2:]]

This issue may also occur if you have multiple versions of the same support library android-support-v4.jar. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.

I had trouble with the existing answers when using multidimensional arrays. This solution works for me.

if (is_array($array)) {
    foreach ($array as $key => $val) {
        $array[$key] = trim($val);
    }
}

40 methods in a single class is a bit much.

Would it make sense to move some of the functionality into other - suitably named - classes. Then it is much easier to make sense of.

When you have fewer, it is much easier to list them in a natural reading order. A frequent paradigm is to list things either before or after you need them , in the order you need them.

This usually means that main() goes on top or on bottom.

If you want to see what is run in the database use dd(DB::getQueryLog()) to see what queries were run.

Try this

BookingDates::where('email', Input::get('email'))
    ->orWhere('name', 'like', '%' . Input::get('name') . '%')->get();

Think about what

if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51))

means. || means "or." The negation of this is (by DeMorgan's Laws):

state == 10 && state == 15 && state == 19...

In other words, the only way that this could be false if if a state equals 10, 15, and 19 (and the rest of the numbers in your or statement) at the same time, which is impossible.

Thus, this statement will always be true. State 15 will never equal state 10, for example, so it's always true that state will either not equal 10 or not equal 15.

Change || to &&.

Also, in most languages, the following:

if (x) {
  return true;
}
else {
  return false;
}

is not necessary. In this case, the method returns true exactly when x is true and false exactly when x is false. You can just do:

return x;

    cin >> lineno ; 



    for (int i = 0; i < lineno ; i++)
    {
        
        getline(file , text[0]);

    }   

    cout << "\nthis is the text in which line you want befor  :: " << text[0] << endl ;
    system("pause");

    return 0;
}

Good luck !

Send params from View to an other View, from Sender View to Receiver View use viewParam and includeViewParams=true

In Sender

1. Declare params to be sent. We can send String, Object,…

Sender.xhtml

<f:metadata>
      <f:viewParam name="ID" value="#{senderMB._strID}" />
</f:metadata>

2. We’re going send param ID, it will be included with “includeViewParams=true” in return String of click button event Click button fire senderMB.clickBtnDetail(dto) with dto from senderMB._arrData

Sender.xhtml

<p:dataTable rowIndexVar="index" id="dataTale"value="#{senderMB._arrData}" var="dto">
      <p:commandButton action="#{senderMB.clickBtnDetail(dto)}" value="??" 
      ajax="false"/>
</p:dataTable>

In senderMB.clickBtnDetail(dto) we assign _strID with argument we got from button event (dto), here this is Sender_DTO and assign to senderMB._strID

Sender_MB.java
    public String clickBtnDetail(sender_DTO sender_dto) {
        this._strID = sender_dto.getStrID();
        return "Receiver?faces-redirect=true&includeViewParams=true";
    }

The link when clicked will become http://localhost:8080/my_project/view/Receiver.xhtml?*ID=12345*

In Recever

1. Get viewParam Receiver.xhtml In Receiver we declare f:viewParam to get param from get request (receive), the name of param of receiver must be the same with sender (page)

Receiver.xhtml

<f:metadata><f:viewParam name="ID" value="#{receiver_MB._strID}"/></f:metadata>

It will get param ID from sender View and assign to receiver_MB._strID

2. Use viewParam In Receiver, we want to use this param in sql query before the page render, so that we use preRenderView event. We are not going to use constructor because constructor will be invoked before viewParam is received So that we add

Receiver.xhtml

<f:event listener="#{receiver_MB.preRenderView}" type="preRenderView" />

into f:metadata tag

Receiver.xhtml

<f:metadata>
<f:viewParam name="ID" value="#{receiver_MB._strID}" />
<f:event listener="#{receiver_MB.preRenderView}"
            type="preRenderView" />
</f:metadata>

Now we want to use this param in our read database method, it is available to use

Receiver_MB.java
public void preRenderView(ComponentSystemEvent event) throws Exception {
        if (FacesContext.getCurrentInstance().isPostback()) {
            return;
        }
        readFromDatabase();
    }
private void readFromDatabase() {
//use _strID to read and set property   
}

Flagrant Badassery has 11 different trims with benchmark information:

http://blog.stevenlevithan.com/archives/faster-trim-javascript

Non-surprisingly regexp-based are slower than traditional loop.

Here is my personal one. This code is old! I wrote it for JavaScript1.1 and Netscape 3 and it has been only slightly updated since. (Original used String.charAt)

/**
 *  Trim string. Actually trims all control characters.
 *  Ignores fancy Unicode spaces. Forces to string.
 */
function trim(str) {
    str = str.toString();
    var begin = 0;
    var end = str.length - 1;
    while (begin <= end && str.charCodeAt(begin) < 33) { ++begin; }
    while (end > begin && str.charCodeAt(end) < 33) { --end; }
    return str.substr(begin, end - begin + 1);
}

For what you want I would've used

    app.get('/fruit/:fruitName&:fruitColor', function(request, response) {
       const name = request.params.fruitName 
       const color = request.params.fruitColor 
    });

or better yet

    app.get('/fruit/:fruit', function(request, response) {
       const fruit = request.params.fruit
       console.log(fruit)
    });

where fruit is a object. So in the client app you just call

https://mydomain.dm/fruit/{"name":"My fruit name", "color":"The color of the fruit"}

and as a response you should see:

    //  client side response
    // { name: My fruit name, color:The color of the fruit}

Although this question is 5 years old I have come across a nice solution.

Use the 'DictionaryEntry' object to pair keys and values.

Set the 'DisplayMember' and 'ValueMember' properties to:

   Me.myComboBox.DisplayMember = "Key"
   Me.myComboBox.ValueMember = "Value"

To add items to the ComboBox:

   Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))

To retreive items like this:

MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)

Based on my experience, solution which is fine(the best) when keys are not important:

$cart = [];
$cart[] = 13;
$cart[] = "foo";
$cart[] = obj;

A nice and clean solution, that doesn't require any external dependencies:

Debouncing with React Hooks

It uses a custom plus the useEffect React hooks and the setTimeout / clearTimeout method.

history.pushState(null, null, document.title);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.title);
});

This script will overwrite attempts to navigate back and forth with the state of the current page.

Update:

Some users have reported better success with using document.URL instead of document.title:

history.pushState(null, null, document.URL);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.URL);
});

I always use this code... Use this code

String clientScriptName = "ButtonClickScript";
Type clientScriptType = this.GetType ();

// Get a ClientScriptManager reference from the Page class.
ClientScriptManager clientScript = Page.ClientScript;

// Check to see if the client script is already registered.
if (!clientScript.IsClientScriptBlockRegistered (clientScriptType, clientScriptName))
    {
     StringBuilder sb = new StringBuilder ();
     sb.Append ("<script type='text/javascript'>");
     sb.Append ("window.open(' " + url + "')"); //URL = where you want to redirect.
     sb.Append ("</script>");
     clientScript.RegisterClientScriptBlock (clientScriptType, clientScriptName, sb.ToString ());
     }

You are looking for the __getitem__ method. See http://docs.python.org/reference/datamodel.html, section 3.4.6

build it with string.Join instead:

var parameters = sl.SelProds.Select(x=>"productID="+x.prodID).ToArray();
paramstr = string.Join("&", parameters);

string.Join takes a seperator ("&") and and array of strings (parameters), and inserts the seperator between each element of the array.

mm is minutes. You want MM for months:

SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy");

Don't feel bad - this exact mistake comes up a lot.

sorted_by_second = sorted(data, key=lambda tup: tup[1])

or:

data.sort(key=lambda tup: tup[1])  # sorts in place

If you use php-fpm, the php_admin_value will NOT work and gives an Internal Server Error.

Instead use this in your .htaccess. It disables the parser in that folder and all subfolders:

I set the state as any[] type. and in the constructor set the state to null.

onServiceChange = (e) => {
    const {value} = e.target;
    const index = this.state.services.indexOf(value);
    const services = this.state.services.filter(item => item !== value);
    this.setState(prevState => ({
        services: index === -1 ? prevState.services.push(value) && prevState.services : this.state.services.filter(item => item !== value)
    }))
}

In the input element

this.onServiceChange(e)}/> this.onServiceChange(e)}/> this.onServiceChange(e)}/> this.onServiceChange(e)}/>

I figured it out after some time. Thought it might help y'all :)

A very simple way to retrieve a connection string, is to create a text file, change the extension from .txt to .udl.

Double-clicking the .udl file will open the Data Link Properties wizard.

Configure and test the connection to your database server.

Close the wizard and open the .udl file with the text editor of your choice and simply copy the connection string (without the Provider=<driver>part) to use it in your C# application.

sample udl file content

[oledb]
; Everything after this line is an OLE DB initstring
Provider=SQLNCLI11.1;Integrated Security=SSPI;Persist Security Info=False;User ID="";Initial Catalog=YOURDATABASENAME;Data Source=YOURSERVERNAME;Initial File Name="";Server SPN=""

what you need to copy from it

Integrated Security=SSPI;Initial Catalog=YOURDATABASENAME;Data Source=YOURSERVERNAME;

If you want to specify username and password you can adopt from other answers.

You have written

background: url('bg.gif') top repeat-y;    
background-size: 490px;

but you will only see the background depending on the size of the container.

if you have an empty container with the background url and whatever the background-size is, you will not see the bg.gif.

If you set the size of the continer to

background: url('bg.gif') top repeat-y;    
background-size: 490px;
height: 490px;
width: 490px;

combined to the code you wrote above, you will be able to see the bg.gif file.

The page sizes are looking different in your PDF because the images were originally set to different DPI (even if images are identical HxW in pixels). The good news is - it's only a display issue - and can be fixed easily.

An image with a higher DPI value would display smaller in a PDF (displays at the 'print-size' of the image). To avoid this, open each image in an image editor like GIMP or Photoshop. Open relevant image print control dialog box and set a suitable uniform DPI info for all the images. Remake the PDF with these new images. If in the new PDF images are too big - redo the DPI setting for each to a higher value. If in the new PDF pages are too small to read on-screen without zooming, again - redo DPI adjustment, this time put a lower DPI value. Ideally, 150 DPI should be good enough for images of 2500X2500 pixel - on a 17 inch monitor set to 1366x768 resolution.

BTW, the PDF file shall print each page at the specified DPI of that page. If all images are same DPI, you'll get a uniform printing.

Hope this helps :)

Here's my attempt at doing this:

Step 1: Create a style named SearchViewStyle

<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the search icon -->
    <item name="searchIcon">@drawable/search</item>
    <!-- Gets rid of the "underline" in the text -->
    <item name="queryBackground">@null</item>
    <!-- Gets rid of the search icon when the SearchView is expanded -->
    <item name="searchHintIcon">@null</item>
    <!-- The hint text that appears when the user has not typed anything -->
    <item name="queryHint">@string/search_hint</item>
</style>

Step 2: Create a layout named simple_search_view_item.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView
    android:layout_gravity="end"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    style="@style/SearchViewStyle"
    xmlns:android="http://schemas.android.com/apk/res/android" />  

Step 3: Create a menu item for this search view

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        app:actionLayout="@layout/simple_search_view_item"
        android:title="@string/search"
        android:icon="@drawable/search"
        app:showAsAction="always" />
</menu>  

Step 4: Inflate the menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_searchable_activity, menu);
    return true;
}  

Result:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar. If someone could help me do that then that'd be golden.

Most likely the remote repository doesn't exist or you have added the wrong one.

You have to first remove the origin and re-add it:

git remote remove origin
git remote add origin https://github.com/username/repository

$@ is all of the parameters passed to the script.

For instance, if you call ./someScript.sh foo bar then $@ will be equal to foo bar.

If you do:

./someScript.sh foo bar

and then inside someScript.sh reference:

umbrella_corp_options "$@"

this will be passed to umbrella_corp_options with each individual parameter enclosed in double quotes, allowing to take parameters with blank space from the caller and pass them on.

Before importing just make sure you have max_allowed_pack value set some thing large else you will get an error: Error 2006 MySQL server gone away.

Then try the command: mysql -u root -p database_name < file.sql

Try this:

UPDATE business AS b
INNER JOIN business_geocode AS g ON b.business_id = g.business_id
SET b.mapx = g.latitude,
  b.mapy = g.longitude
WHERE  (b.mapx = '' or b.mapx = 0) and
  g.latitude > 0

Update:

Since you said the query yielded a syntax error, I created some tables that I could test it against and confirmed that there is no syntax error in my query:

mysql> create table business (business_id int unsigned primary key auto_increment, mapx varchar(255), mapy varchar(255)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> create table business_geocode (business_geocode_id int unsigned primary key auto_increment, business_id int unsigned not null, latitude varchar(255) not null, longitude varchar(255) not null, foreign key (business_id) references business(business_id)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> UPDATE business AS b
    -> INNER JOIN business_geocode AS g ON b.business_id = g.business_id
    -> SET b.mapx = g.latitude,
    ->   b.mapy = g.longitude
    -> WHERE  (b.mapx = '' or b.mapx = 0) and
    ->   g.latitude > 0;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0

See? No syntax error. I tested against MySQL 5.5.8.

You can see SNS as a traditional topic which you can have multiple Subscribers. You can have heterogeneous subscribers for one given SNS topic, including Lambda and SQS, for example. You can also send SMS messages or even e-mails out of the box using SNS. One thing to consider in SNS is only one message (notification) is received at once, so you cannot take advantage from batching.

SQS, on the other hand, is nothing but a queue, where you store messages and subscribe one consumer (yes, you can have N consumers to one SQS queue, but it would get messy very quickly and way harder to manage considering all consumers would need to read the message at least once, so one is better off with SNS combined with SQS for this use case, where SNS would push notifications to N SQS queues and every queue would have one subscriber, only) to process these messages. As of Jun 28, 2018, AWS Supports Lambda Triggers for SQS, meaning you don't have to poll for messages any more.

Furthermore, you can configure a DLQ on your source SQS queue to send messages to in case of failure. In case of success, messages are automatically deleted (this is another great improvement), so you don't have to worry about the already processed messages being read again in case you forgot to delete them manually. I suggest taking a look at Lambda Retry Behaviour to better understand how it works.

One great benefit of using SQS is that it enables batch processing. Each batch can contain up to 10 messages, so if 100 messages arrive at once in your SQS queue, then 10 Lambda functions will spin up (considering the default auto-scaling behaviour for Lambda) and they'll process these 100 messages (keep in mind this is the happy path as in practice, a few more Lambda functions could spin up reading less than the 10 messages in the batch, but you get the idea). If you posted these same 100 messages to SNS, however, 100 Lambda functions would spin up, unnecessarily increasing costs and using up your Lambda concurrency.

However, if you are still running traditional servers (like EC2 instances), you will still need to poll for messages and manage them manually.

You also have FIFO SQS queues, which guarantee the delivery order of the messages. SQS FIFO is also supported as an event source for Lambda as of November 2019

Even though there's some overlap in their use cases, both SQS and SNS have their own spotlight.

Use SNS if:

• multiple subscribers is a requirement
• sending SMS/E-mail out of the box is handy

Use SQS if:

• only one subscriber is needed
• batching is important

You can create a function:

function changeInputType(oldObj, oTyp, nValue) {
  var newObject = document.createElement('input');
  newObject.type = oTyp;
  if(oldObj.size) newObject.size = oldObj.size;
  if(oldObj.value) newObject.value = nValue;
  if(oldObj.name) newObject.name = oldObj.name;
  if(oldObj.id) newObject.id = oldObj.id;
  if(oldObj.className) newObject.className = oldObj.className;
  oldObj.parentNode.replaceChild(newObject,oldObj);
  return newObject;
}

And you do a call like:

changeInputType(document.getElementById('DATE_RANGE_VALUE'), 'checkbox', 7);

Here is my answer for this given a string returnURL which is like http://host.com/?param1=abc&param2=cde. It's fairly basic as I'm beginning at JavaScript (this is actually part of my first program ever in JS), and making it simpler to understand rather than tricky.

Notes

• No sanity checking of values
• Just outputting to the console - you'll want to store them in an array or something

• this is only for GET, and not POST

  var paramindex = returnURL.indexOf('?');
  if (paramindex > 0) {
      var paramstring = returnURL.split('?')[1];
      while (paramindex > 0) {
          paramindex = paramstring.indexOf('=');
          if (paramindex > 0) {
              var parkey = paramstring.substr(0,paramindex);
              console.log(parkey)
              paramstring = paramstring.substr(paramindex+1) // +1 to strip out the =
          }
          paramindex = paramstring.indexOf('&');
          if (paramindex > 0) {
              var parvalue = paramstring.substr(0,paramindex);
              console.log(parvalue)
              paramstring = paramstring.substr(paramindex+1) // +1 to strip out the &
          } else { // we're at the end of the URL
              var parvalue = paramstring
              console.log(parvalue)
              break;
          }
      }
  }
  

In many cases, I believe @allcaps's answer works well.

However, sometimes it is necessary to actually rename an app, e.g. to improve code readability or prevent confusion.

Most of the other answers involve either manual database manipulation or tinkering with existing migrations, which I do not like very much.

As an alternative, I like to create a new app with the desired name, copy everything over, make sure it works, then remove the original app:

1. Start a new app with the desired name, and copy all code from the original app into that. Make sure you fix the namespaced stuff, in the newly copied code, to match the new app name.

2. makemigrations and migrate

3. Create a data migration that copies the relevant data from the original app's tables into the new app's tables, and migrate again.

At this point, everything still works, because the original app and its data are still in place.

4. Now you can refactor all the dependent code, so it only makes use of the new app. See other answers for examples of what to look out for.

5. Once you are certain that everything works, you can remove the original app.

This has the advantage that every step uses the normal Django migration mechanism, without manual database manipulation, and we can track everything in source control. In addition, we keep the original app and its data in place until we are sure everything works.

Late, but relevant to request and hopefully helpful. If using an external service (as suggested in the reply by CommonsWare) then Docmosis has a cloud service that might help - offloading processing to a cloud service that does the heavy processing. That approach is ideal in some circumstances but of course relies on being net-connected.

To update this for Python-3 you can do this

"{} {}".format(True, False)

However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.

>>> "{:<8} {}".format(True, False)
'1        False'

To get around this you can cast True as a string, e.g.

>>> "{:<8} {}".format(str(True), False)
'True     False'

I'm going to assume that the two arrays you've given for PHP and JS are not related, and they're just examples of how arrays look in the two languages. Clearly you're not going to be able to convert those sequences of letters and numbers into those city names.

PHP provides a function to convert PHP arrays into Javascript code: json_encode(). (technically, it's JSON format; JSON stands for JavaScript Object Notation)

Use it like this:

<script type='text/javascript'>
<?php
$php_array = array('abc','def','ghi');
$js_array = json_encode($php_array);
echo "var javascript_array = ". $js_array . ";\n";
?>
</script>

See also the manual page I linked above for more information.

Note that json_encode() is only available in PHP 5.2 and up, so if you're using an older version, you'll need to use an existing one -- the PHP manual page also includes comments with functions written by people who needed it. (but that said, if you're using anything older than PHP 5.2 you should upgrade ASAP)

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

You could also use this:

$('.slider').slick({
   //other settings ................
   respondTo: 'slider', //makes the slider to change width depending on the container it is in
   adaptiveHeight: true //makes the height change depending on the height of the element inside
})

from row in TableA select row

Or just:

TableA

In method syntax, with other operators:

TableA.Where(row => row.IsInteresting) // no .Select(), returns the whole row.

Essentially, you already are selecting all columns, the select then transforms that to the columns you care about, so you can even do things like:

from user in Users select user.LastName+", "+user.FirstName

That's fine. To understand the above, you have to understand the nature of abstract classes first. They are similar to interfaces in that respect. This is what Oracle say about this here.

Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation.

So you have to think about what happens when an interface extends another interface. For example ...

//Filename: Sports.java
public interface Sports
{
   public void setHomeTeam(String name);
   public void setVisitingTeam(String name);
}

//Filename: Football.java
public interface Football extends Sports
{
   public void homeTeamScored(int points);
   public void visitingTeamScored(int points);
   public void endOfQuarter(int quarter);
}

... as you can see, this also compiles perfectly fine. Simply because, just like an abstract class, an interface can NOT be instantiated. So, it is not required to explicitly mention the methods from its "parent". However, ALL the parent method signatures DO implicitly become a part of the extending interface or implementing abstract class. So, once a proper class (one that can be instantiated) extends the above, it WILL be required to ensure that every single abstract method is implemented.

Hope that helps... and Allahu 'alam !

sqlitejdbc code can be downloaded using git from https://github.com/crawshaw/sqlitejdbc.

This is not so much an answer to your original question as to one of the queries you had in the body of your question.

A little preamble, so that my naming doesn't seem strange:

ax = self.figure.add_subplot( 111 )

As has been mentioned you can use ticklabel_format to specify that matplotlib should use scientific notation for large or small values:

ax.ticklabel_format(style='sci',scilimits=(-3,4),axis='both')

You can affect the way that this is displayed using the flags in rcParams (from matplotlib import rcParams) or by setting them directly. I haven't found a more elegant way of changing between '1e' and 'x10^' scientific notation than:

ax.xaxis.major.formatter._useMathText = True

This should give you the more Matlab-esc, and indeed arguably better appearance. I think the following should do the same:

rc('text', usetex=True)

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

Pretty late to the party, but here's my two cents:

Use a LinkedHashSet

I assume what you need is a collection which:

• disallows you to insert duplicates;
• retains insertion order.

LinkedHashSet does this. The advantage over using an ArrayList is that LinkedHashSet has a complexity of O(1) for the contains operation, as opposed to ArrayList, which has O(n).

^{Of course, you need to implement your object's equals and hashCode methods properly.}

        List<int> list1 = new List<int>();
        List<int> list2 = new List<int>();
        List<int> listDifference = new List<int>();

        foreach (var item1 in list1)
        {
            foreach (var item2 in list2)
            {
                if (item1 != item2)
                    listDifference.Add(item1);
            }
        }

In the case of Maven project

Try right click on the project then select Maven -> Update Project... then Ok

No CSS required, visible class should like this: visible-md-block not just visible-md and the code should be like this:

<div class="containerdiv hidden-sm hidden-xs visible-md-block visible-lg-block">
    <div class="row">
        <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4 logo">

        </div>
    </div>
</div>

<div class="mobile hidden-md hidden-lg ">
    test
</div>

Extra css is not required at all.

Check this out: http://download.oracle.com/javase/1,5.0/docs/api/java/math/BigDecimal.html#divideAndRemainder%28java.math.BigDecimal%29

You just need to wrap your int or long variable in a BigDecimal object, then invoke the divideAndRemainder method on it. The returned array will contain the quotient and the remainder (in that order).

You can assign it to a hidden field, and retrieve it using

var value= Request.Form["value"]

You'll get converting errors with:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

Use instead:

string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
    found = true; 
} else {
    found = false; 
}

I had this problem in one legacy application that create prepared statement dynamically.

String firstName;
StringBuilder query =new StringBuilder("select id, name from employee where country_Code=1");
query.append("and  name like '");
query.append(firstName + "' ");
query.append("and ssn=?");
PreparedStatement preparedStatement =new prepareStatement(query.toString());

when it try to set value for ssn, it was giving invalid column index error, and finally found out that it is caused by firstName having ' within; that disturb the syntax.

The following is a proposed solution for the OP's specific problem (extracting the 2nd word of a string), but it should be noted that, as mc0e's answer states, actually extracting regex matches is not supported out-of-the-box in MySQL. If you really need this, then your choices are basically to 1) do it in post-processing on the client, or 2) install a MySQL extension to support it.

BenWells has it very almost correct. Working from his code, here's a slightly adjusted version:

SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
)

As a working example, I used:

SELECT SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
) as string
FROM (SELECT 'THIS IS A TEST' AS sentence) temp

This successfully extracts the word IS

As far as I know, you can go with c#.

You can also use the obscure language "Boo". (Found at https://boo-language.github.io/)

In the past (before about 2012) it was possible to use a strange variant of Java but that is now deprecated and does not work.

Note that Unity builds to Android / iOS, and many other platforms. The fact that iOS programming uses objective-c or Swift, is, completely irrelevant at the Unity3D level. Unity is programmed using c#.

Visual Studio Code is an editor while Visual Studio is an IDE.

Visual Studio Code is cross-platform and fast, while Visual Studio is not fast.

Note that Visual Studio for Mac is available now but is a different product compared to Visual Studio (Windows). It's based on Xamarin Studio and lacks support for some older .NET project types. It does successfully build solutions created in Visual Studio 2017. Visual Studio for Mac has a more limited UI (for example, no customizable toolbar). So for cross-platform work, Visual Studio Code may still be preferable.

You can also plot to a png file using gnuplot (which is free):

terminal commands

gnuplot> set title '<title>'
gnuplot> set ylabel '<yLabel>'
gnuplot> set xlabel '<xLabel>'
gnuplot> set grid
gnuplot> set term png
gnuplot> set output '<Output file name>.png'
gnuplot> plot '<fromfile.csv>'

note: you always need to give the right extension (.png here) at set output

Then it is also possible that the ouput is not lines, because your data is not continues. To fix this simply change the 'plot' line to:

plot '<Fromfile.csv>' with line lt -1 lw 2

More line editing options (dashes and line color ect.) at: http://gnuplot.sourceforge.net/demo_canvas/dashcolor.html

• gnuplot is available in most linux distros via the package manager (e.g. on an apt based distro, run apt-get install gnuplot)
• gnuplot is available in windows via Cygwin
• gnuplot is available on macOS via homebrew (run brew install gnuplot)

I will post the new "way" with androidx in a short answer (because in some case you does not need custom registry or contract). If you want more informations see : https://developer.android.com/training/basics/intents/result

Important : there is actually a bug with the backward compatibility of androidx so you have to add fragment_version in your gradle file. Otherwise you will get an exception "New result API error : Can only use lower 16 bits for requestCode".

dependencies {

    def activity_version = "1.2.0-beta01"
    // Java language implementation
    implementation "androidx.activity:activity:$activity_version"
    // Kotlin
    implementation "androidx.activity:activity-ktx:$activity_version"

    def fragment_version = "1.3.0-beta02"
    // Java language implementation
    implementation "androidx.fragment:fragment:$fragment_version"
    // Kotlin
    implementation "androidx.fragment:fragment-ktx:$fragment_version"
    // Testing Fragments in Isolation
    debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}

Now you just have to add this member variable of your activity. This use a predefined registry and generic contract.

public class MyActivity extends AppCompatActivity{

   ...

    /**
     * Activity callback API.
     */
    // https://developer.android.com/training/basics/intents/result
    private ActivityResultLauncher<Intent> mStartForResult = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),

            new ActivityResultCallback<ActivityResult>() {

                @Override
                public void onActivityResult(ActivityResult result) {
                    switch (result.getResultCode()) {
                        case Activity.RESULT_OK:
                            Intent intent = result.getData();
                            // Handle the Intent
                            Toast.makeText(MyActivity.this, "Activity returned ok", Toast.LENGTH_SHORT).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(MyActivity.this, "Activity canceled", Toast.LENGTH_SHORT).show();
                            break;
                    }
                }
            });

Before new API you had :

btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MyActivity .this, EditActivity.class);
                startActivityForResult(intent, Constants.INTENT_EDIT_REQUEST_CODE);
            }
        });

You may notice that the request code is now generated (and holded) by the google framework. Your code become.

 btn.setOnClickListener(new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    Intent intent = new Intent(MyActivity .this, EditActivity.class);
                    mStartForResult.launch(intent);
                }
            });

Hope my answer will help some people !

Use typeof:

> typeof "foo"
"string"
> typeof true
"boolean"
> typeof 42
"number"

So you can do:

if(typeof bar === 'number') {
   //whatever
}

Be careful though if you define these primitives with their object wrappers (which you should never do, use literals where ever possible):

> typeof new Boolean(false)
"object"
> typeof new String("foo")
"object"
> typeof new Number(42)
"object"

The type of an array is still object. Here you really need the instanceof operator.

Update:

Another interesting way is to examine the output of Object.prototype.toString:

> Object.prototype.toString.call([1,2,3])
"[object Array]"
> Object.prototype.toString.call("foo bar")
"[object String]"
> Object.prototype.toString.call(45)
"[object Number]"
> Object.prototype.toString.call(false)
"[object Boolean]"
> Object.prototype.toString.call(new String("foo bar"))
"[object String]"
> Object.prototype.toString.call(null)
"[object Null]"
> Object.prototype.toString.call(/123/)
"[object RegExp]"
> Object.prototype.toString.call(undefined)
"[object Undefined]"

With that you would not have to distinguish between primitive values and objects.

Hi this issue is because docker containers exit if there is no running application in the container.

-d 

option is just to run a container in deamon mode.

So the trick to make your container continuously running is point to a shell file in docker which will keep your application running.You can try with a start.sh file

Eg: docker run -d centos sh /yourlocation/start.sh

This start.sh should point to a never ending application.

In case if you dont want any application to be running,you can install monit which will keep your docker container running. Please let us know if these two cases worked for you to keep your container running.

All the best

A definition from another perspective:

Apache Camel is an integration framework. It consists of some Java libraries, which helps you implementing integration problems on the Java platform. What this means and how it differs from APIs on the one side and an Enterprise Service Bus (ESB) on the other side is described in my article "When to use Apache Camel".

For unsigned numbers you can use these classes from Guava library:

• UnsignedInteger
• UnsignedLong

They support various operations:

• plus
• minus
• times
• mod
• dividedBy

The thing that seems missing at the moment are byte shift operators. If you need those you can use BigInteger from Java.

You can use segments to add the bars in base graphics. Here epsilon controls the line across the top and bottom of the line.

plot (x, y, ylim=c(0, 6))
epsilon = 0.02
for(i in 1:5) {
    up = y[i] + sd[i]
    low = y[i] - sd[i]
    segments(x[i],low , x[i], up)
    segments(x[i]-epsilon, up , x[i]+epsilon, up)
    segments(x[i]-epsilon, low , x[i]+epsilon, low)
}

As @thelatemail points out, I should really have used vectorised function calls:

segments(x, y-sd,x, y+sd)
epsilon = 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

Firstly, System.currentTimeMillis() and Instant.now() are not ideal for timing. They both report the wall-clock time, which the computer doesn't know precisely, and which can move erratically, including going backwards if for example the NTP daemon corrects the system time. If your timing happens on a single machine then you should instead use System.nanoTime().

Secondly, from Java 8 onwards java.time.Duration is the best way to represent a duration:

long start = System.nanoTime();
// do things...
long end = System.nanoTime();
Duration duration = Duration.ofNanos(end - start);
System.out.println(duration); // Prints "PT18M19.511627776S"
System.out.printf("%d Hours %d Minutes %d Seconds%n",
        duration.toHours(), duration.toMinutes() % 60, duration.getSeconds() % 60);
// prints "0 Hours 18 Minutes 19 Seconds"

If your repo is of HTTPS repo, git config -e give this command in the git bash. Update the username and password by opening in insert mode, change the password or username give :x and Cntrl+z keys it will save and exit

So, From then while you pull / push the code to the repository it will not ask for password.

The Trace messages can occur in the output window as well, even if you're not in debug mode. You just have to make sure the the TRACE compiler constant is defined.

Using the command line:

Enter ls -al ~/.ssh to see if existing SSH keys are present.

In the terminal is shows: No directory exist

Then generate a new SSH key

Step 1.

ssh-keygen -t rsa -b 4096 -C "[email protected]"

step 2.

Enter a file in which to save the key (/Users/you/.ssh/id_rsa): <here is file name and enter the key>

step 3.

Enter passphrase (empty for no passphrase): [Type a password]

Enter same passphrase again: [Type password again]

Array: [1, 2, 3, 4]
Result: ["foo1", "foo2", "foo3", "foo4"]

Array.prototype.map() Keep original array

const originalArr = ["Iron", "Super", "Ant", "Aqua"];
const modifiedArr = originalArr.map(name => `${name}man`);

console.log( "Original: %s", originalArr );
console.log( "Modified: %s", modifiedArr );

Array.prototype.forEach() Override original array

const originalArr = ["Iron", "Super", "Ant", "Aqua"];
originalArr.forEach((name, index) => originalArr[index] = `${name}man`);

console.log( "Overridden: %s", originalArr );

Suppose your DataTable has the following columns try this code:

DataTable dt =new DataTable();
txtTGrossWt.Text = dt.Compute("sum(fldGrossWeight)", "").ToString() == "" ? "0" : dt.Compute("sum(fldGrossWeight)", "").ToString();
txtTOtherWt.Text = dt.Compute("sum(fldOtherWeight)", "").ToString() == "" ? "0" : dt.Compute("sum(fldOtherWeight)", "").ToString();
txtTNetWt.Text = dt.Compute("sum(fldNetWeight)", "").ToString() == "" ? "0" : dt.Compute("sum(fldNetWeight)", "").ToString();
txtFinalValue.Text = dt.Compute("sum(fldValue)", "").ToString() == "" ? "0" : dt.Compute("sum(fldValue)", "").ToString();

What might be informing you coworker is a notion that most C++ code should be templated to allow for maximum usability. And if it's templated, then everything will need to be in a header file, so that client code can see it and instantiate it. If it's good enough for Boost and the STL, it's good enough for us.

I don't agree with this point of view, but it may be where it's coming from.

Many great answers, but for visual learners: Firstly lets explore with arguments to super, and then without.

Imagine theres an instance jack created from the class Jack, who has the inheritance chain as shown in green in the picture. Calling:

super(Jack, jack).method(...)

will use the MRO (Method Resolution Order) of jack (its inheritance tree in a certain order), and will start searching from Jack. Why can one provide a parent class? Well if we start searching from the instance jack, it would find the instance method, the whole point is to find its parents method.

If one does not supply arguments to super, its like the first argument passed in is the class of self, and the second argument passed in is self. These are auto-calculated for you in Python3.

However say we dont want to use Jack's method, instead of passing in Jack, we could of passed in Jen to start searching upwards for the method from Jen.

It searches one layer at a time (width not depth), e.g. if Adam and Sue both have the required method, the one from Sue will be found first.

If Cain and Sue both had the required method, Cain's method would be called first. This corresponds in code to:

Class Jen(Cain, Sue):

MRO is from left to right.

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum.

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;
}

Then when you call your method you pass the SupportedPermissions value to your method

  var basicFile = CreateFile(myId, myName, myDescription, SupportedPermissions.basic);

Here is my answer:

var str = '[me nombre es] : My name is. [Yo puedo] is the right word'; 

var reg = /\[(.*?)\]/g;

var a = str.match(reg);

a = a.toString().replace(/[\[\]]/g, "").split(','));

For PHP7.1 install this

sudo apt-get install php7.1-zip

Really annoying thing in PS 5, where $_ won't be the full path within foreach. These are the string versions of FileInfo and DirectoryInfo objects. For some reason a wildcard in the path fixes it, or use Powershell 6 or 7. You can also pipe to get-item in the middle.

Get-ChildItem -path C:\WINDOWS\System32\*.txt -Recurse | foreach { "$_" }

Get-ChildItem -path C:\WINDOWS\System32 -Recurse | get-item | foreach { "$_" }

This seems to have been an issue with .Net that got resolved in .Net Core (Powershell 7): Stringification behavior of FileInfo / Directory instances has changed since v6.0.2 #7132

Note that Git 1.9/2.0 (Q1 2014) has removed that limitation.
See commit 82fba2b, from Nguy?n Thái Ng?c Duy (pclouds):

Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore.

The documentation now reads:

--depth <depth>::

Create a 'shallow' clone with a history truncated to the specified number of revisions.

That stems from commits like 0d7d285, f2c681c, and c29a7b8 which support clone, send-pack /receive-pack with/from shallow clones.
smart-http now supports shallow fetch/clone too.

All the details are in "shallow.c: the 8 steps to select new commits for .git/shallow".

Update June 2015: Git 2.5 will even allow for fetching a single commit!
(Ultimate shallow case)

Update January 2016: Git 2.8 (Mach 2016) now documents officially the practice of getting a minimal history.
See commit 99487cf, commit 9cfde9e (30 Dec 2015), commit 9cfde9e (30 Dec 2015), commit bac5874 (29 Dec 2015), and commit 1de2e44 (28 Dec 2015) by Stephen P. Smith (``).
^{(Merged by Junio C Hamano -- gitster -- in commit 7e3e80a, 20 Jan 2016)}

This is "Documentation/user-manual.txt"

A <<def_shallow_clone,shallow clone>> is created by specifying the git-clone --depth switch.
The depth can later be changed with the git-fetch --depth switch, or full history restored with --unshallow.

Merging inside a <<def_shallow_clone,shallow clone>> will work as long as a merge base is in the recent history.
Otherwise, it will be like merging unrelated histories and may have to result in huge conflicts.
This limitation may make such a repository unsuitable to be used in merge based workflows.

Update 2020:

• git 2.11.1 introduced option git fetch --shallow-exclude= to prevent fetching all history
• git 2.11.1 introduced option git fetch --shallow-since= to prevent fetching old commits.

For more on the shallow clone update process, see "How to update a git shallow clone?".

As commented by Richard Michael:

to backfill history: git pull --unshallow

And Olle Härstedt adds in the comments:

To backfill part of the history: git fetch --depth=100.

As shown by @Maglob, the basic approach is to test the conversion from string to date using SimpleDateFormat.parse. That will catch invalid day/month combinations like 2008-02-31.

However, in practice that is rarely enough since SimpleDateFormat.parse is exceedingly liberal. There are two behaviours you might be concerned with:

Invalid characters in the date string Surprisingly, 2008-02-2x will "pass" as a valid date with locale format = "yyyy-MM-dd" for example. Even when isLenient==false.

Years: 2, 3 or 4 digits? You may also want to enforce 4-digit years rather than allowing the default SimpleDateFormat behaviour (which will interpret "12-02-31" differently depending on whether your format was "yyyy-MM-dd" or "yy-MM-dd")

A Strict Solution with the Standard Library

So a complete string to date test could look like this: a combination of regex match, and then a forced date conversion. The trick with the regex is to make it locale-friendly.

  Date parseDate(String maybeDate, String format, boolean lenient) {
    Date date = null;

    // test date string matches format structure using regex
    // - weed out illegal characters and enforce 4-digit year
    // - create the regex based on the local format string
    String reFormat = Pattern.compile("d+|M+").matcher(Matcher.quoteReplacement(format)).replaceAll("\\\\d{1,2}");
    reFormat = Pattern.compile("y+").matcher(reFormat).replaceAll("\\\\d{4}");
    if ( Pattern.compile(reFormat).matcher(maybeDate).matches() ) {

      // date string matches format structure, 
      // - now test it can be converted to a valid date
      SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance();
      sdf.applyPattern(format);
      sdf.setLenient(lenient);
      try { date = sdf.parse(maybeDate); } catch (ParseException e) { }
    } 
    return date;
  } 

  // used like this:
  Date date = parseDate( "21/5/2009", "d/M/yyyy", false);

Note that the regex assumes the format string contains only day, month, year, and separator characters. Aside from that, format can be in any locale format: "d/MM/yy", "yyyy-MM-dd", and so on. The format string for the current locale could be obtained like this:

Locale locale = Locale.getDefault();
SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance(DateFormat.SHORT, locale );
String format = sdf.toPattern();

Joda Time - Better Alternative?

I've been hearing about joda time recently and thought I'd compare. Two points:

1. Seems better at being strict about invalid characters in the date string, unlike SimpleDateFormat
2. Can't see a way to enforce 4-digit years with it yet (but I guess you could create your own DateTimeFormatter for this purpose)

It's quite simple to use:

import org.joda.time.format.*;
import org.joda.time.DateTime;

org.joda.time.DateTime parseDate(String maybeDate, String format) {
  org.joda.time.DateTime date = null;
  try {
    DateTimeFormatter fmt = DateTimeFormat.forPattern(format);
    date =  fmt.parseDateTime(maybeDate);
  } catch (Exception e) { }
  return date;
}

According to the git-stash manpage, "A stash is represented as a commit whose tree records the state of the working directory, and its first parent is the commit at HEAD when the stash was created," and git stash show -p gives us "the changes recorded in the stash as a diff between the stashed state and its original parent.

To keep your other changes intact, use git stash show -p | patch --reverse as in the following:

Edit:

A light improvement to this is to use git apply in place of patch:

git stash show -p | git apply --reverse

Alternatively, you can also use git apply -R as a shorthand to git apply --reverse.

I've been finding this really handy lately...

     setInterval(function(a,b,c){

          console.log(a + b +c);  

      }, 500, 1,2,3);

                    AND Routine_Type = 'FUNCTION' ) 

for functions, and change Routine_Type for stored procedures

IF EXISTS ( SELECT  1
            FROM    Information_schema.Routines
            WHERE   Specific_schema = 'dbo'
                    AND specific_name = 'Foo'
                    AND Routine_Type = 'PROCEDURE' ) 

There are too many answers here, and the selected answer will work for most of the cases.

In my case, I had a 2D array, and array_values for some odd reason was removing the keys on the inner arrays. So I end up with this:

$keys = array_keys($myArray); // Fetches all the keys
$firstElement = $myArray[$keys[0]]; // Get the first element using first key

Here is the code that worked for me!

Assuming that you have a valid session going,

//Get the current users id
$uid = $facebook->getUser();

//create the url
$profile_pic =  "http://graph.facebook.com/".$uid."/picture";

//echo the image out
echo "<img src=\"" . $profile_pic . "\" />";

Thanx goes to Raine, you da man!

You can use the keyword IDENTITY as the data type to the column along with PRIMARY KEY constraint when creating the table.
ex:

StudentNumber IDENTITY(1,1) PRIMARY KEY

In here the first '1' means the starting value and the second '1' is the incrementing value.

echo $myarray[0]->['email'];

Try this only if it you are passing the stdclass object

Recursion works best with what I like to call "fractal problems", where you're dealing with a big thing that's made of smaller versions of that big thing, each of which is an even smaller version of the big thing, and so on. If you ever have to traverse or search through something like a tree or nested identical structures, you've got a problem that might be a good candidate for recursion.

People avoid recursion for a number of reasons:

1. Most people (myself included) cut their programming teeth on procedural or object-oriented programming as opposed to functional programming. To such people, the iterative approach (typically using loops) feels more natural.

2. Those of us who cut our programming teeth on procedural or object-oriented programming have often been told to avoid recursion because it's error prone.

3. We're often told that recursion is slow. Calling and returning from a routine repeatedly involves a lot of stack pushing and popping, which is slower than looping. I think some languages handle this better than others, and those languages are most likely not those where the dominant paradigm is procedural or object-oriented.

4. For at least a couple of programming languages I've used, I remember hearing recommendations not to use recursion if it gets beyond a certain depth because its stack isn't that deep.
