If we have a code:

<div id="myDiv" class="myClass myClass2"></div> 

to take class name by using jQuery we could define and use a simple plugin method:

$.fn.class = function(){
  return Array.prototype.slice.call( $(this)[0].classList );
}

or

 $.fn.class = function(){
   return $(this).prop('class');
 } 

The use of the method will be:

$('#myDiv').class();

We have to notice that it will return a list of classes unlike of native method element.className which returns only first class of the attached classes. Because often the element has more than one class attached to it, I recommend you not to use this native method but element.classlist or the method described above.

The first variant of it will return a list of classes as an array, the second as a string - class names separated by spaces:

// [myClass, myClass2]
// "myClass myClass2"

Another important notice is that both methods as well as jQuery method

$('div').prop('class');

return only class list of the first element caught by the jQuery object if we use a more common selector which points many other elements. In such a case we have to mark the element, we want to get his classes, by using some index, e.g.

$('div:eq(2)').prop('class');

It depends also what you need to do with these classes. If you want just to check for a class into the class list of the element with this id you should just use method "hasClass":

if($('#myDiv').hasClass('myClass')){
   // do something
}

as mentioned in the comments above. But if you could need to take all classes as a selector, then use this code:

$.fn.classes = function(){
   var o = $(this);
   return o.prop('class')? [''].concat( o.prop('class').split(' ') ).join('.') : '';
 } 

 var mySelector = $('#myDiv').classes();

The result will be:

// .myClass.myClass2

and you could get it to create dynamically a specific rewriting css rule for example.

Not sure whether this answer has already appeared...

For the particular pattern in the question, you can just do it with a single grep() call,

grep("A[169]", myfile$Letter)

I am using those commands on MacOs after getting the same error

sudo /usr/local/mysql/support-files/mysql.server start

sudo /usr/local/mysql/support-files/mysql.server stop

sudo /usr/local/mysql/support-files/mysql.server restart

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

This is what worked for me

curl --form file='@filename' URL

It seems when I gave this answer (4+ years ago), I didn't really understand the question, or how form fields worked. I was just answering based on what I had tried in a difference scenario, and it worked for me.

So firstly, the only mistake the OP made was in not using the @ symbol before the file name. Secondly, my answer which uses file=... only worked for me because the form field I was trying to do the upload for was called file. If your form field is called something else, use that name instead.

Explanation

From the curl manpages; under the description for the option --form it says:

This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.

Chances are that if you are trying to do a form upload, you will most likely want to use the @ prefix to upload the file rather than < which uploads the contents of the file.

Addendum

Now I must also add that one must be careful with using the < symbol because in most unix shells, < is the input redirection symbol [which coincidentally will also supply the contents of the given file to the command standard input of the program before <]. This means that if you do not properly escape that symbol or wrap it in quotes, you may find that your curl command does not behave the way you expect.

On that same note, I will also recommend quoting the @ symbol.

You may also be interested in this other question titled: application/x-www-form-urlencoded or multipart/form-data?

I say this because curl offers other ways of uploading a file, but they differ in the content-type set in the header. For example the --data option offers a similar mechanism for uploading files as data, but uses a different content-type for the upload.

Anyways that's all I wanted to say about this answer since it started to get more upvotes. I hope this helps erase any confusions such as the difference between this answer and the accepted answer. There is really none, except for this explanation.

It's in fact almost the same in Python.. :-)

import datetime
year = datetime.date.today().year

Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:

import datetime
year = datetime.datetime.today().year

(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).

One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.

Use -n or --line-number.

Check out man grep for lots more options.

Test with [char]9, such as:

$Tab = [char]9
Write-Output "$Tab hello"

Output:

     hello

In Short :

Carriage_return(\r or 0xD): To take control at starting of same line.

Line_Feed(\n or 0xA): To Take control at starting of next line.

form_feed(\f or 0xC): To take control at starting of next page.

There is no difference in terms of functionality. In fact, both do this:

return this.Add(new SqlParameter(parameterName, value));

The reason they deprecated the old one in favor of AddWithValue is to add additional clarity, as well as because the second parameter is object, which makes it not immediately obvious to some people which overload of Add was being called, and they resulted in wildly different behavior.

Take a look at this example:

 SqlCommand command = new SqlCommand();
 command.Parameters.Add("@name", 0);

At first glance, it looks like it is calling the Add(string name, object value) overload, but it isn't. It's calling the Add(string name, SqlDbType type) overload! This is because 0 is implicitly convertible to enum types. So these two lines:

 command.Parameters.Add("@name", 0);

and

 command.Parameters.Add("@name", 1);

Actually result in two different methods being called. 1 is not convertible to an enum implicitly, so it chooses the object overload. With 0, it chooses the enum overload.

Try either multi-table update syntax

UPDATE config t1 JOIN config t2
    ON t1.config_name = 'name1' AND t2.config_name = 'name2'
   SET t1.config_value = 'value',
       t2.config_value = 'value2';

Here is SQLFiddle demo

or conditional update

UPDATE config
   SET config_value = CASE config_name 
                      WHEN 'name1' THEN 'value' 
                      WHEN 'name2' THEN 'value2' 
                      ELSE config_value
                      END
 WHERE config_name IN('name1', 'name2');

workmad3 is apparently out of date, at least for current gpg, as the --allow-secret-key-import is now obsolete and does nothing.

What happened to me was that I failed to export properly. Just doing gpg --export is not adequate, as it only exports the public keys. When exporting keys, you have to do

gpg --export-secret-keys >keyfile

Specifying pointer-events: none in CSS disables mouse input but doesn't disable keyboard input. For example, the user can still tab to the link and "click" it by pressing the Enter key or (in Windows) the ? Menu key. You could disable specific keystrokes by intercepting the keydown event, but this would likely confuse users relying on assistive technologies.

Probably the best way to disable a link is to remove its href attribute, making it a non-link. You can do this dynamically with a conditional href attribute binding:

<a *ngFor="let link of links"
   [attr.href]="isDisabled(link) ? null : '#'"
   [class.disabled]="isDisabled(link)"
   (click)="!isDisabled(link) && onClick(link)">
   {{ link.name }}
</a>

Or, as in Günter Zöchbauer's answer, you can create two links, one normal and one disabled, and use *ngIf to show one or the other:

<ng-template ngFor #link [ngForOf]="links">
    <a *ngIf="!isDisabled(link)" href="#" (click)="onClick(link)">{{ link.name }}</a>
    <a *ngIf="isDisabled(link)" class="disabled">{{ link.name }}</a>
</ng-template>

Here's some CSS to make the link look disabled:

a.disabled {
    color: gray;
    cursor: not-allowed;
    text-decoration: underline;
}

You can go to jwt.io, paste your token and read the contents. This is jarring for a lot of people initially.

The short answer is that JWT doesn't concern itself with encryption. It cares about validation. That is to say, it can always get the answer for "Have the contents of this token been manipulated"? This means user manipulation of the JWT token is futile because the server will know and disregard the token. The server adds a signature based on the payload when issuing a token to the client. Later on it verifies the payload and matching signature.

The logical question is what is the motivation for not concerning itself with encrypted contents?

1. The simplest reason is because it assumes this is a solved problem for the most part. If dealing with a client like the web browser for example, you can store the JWT tokens in a cookie that is secure (is not transmitted via HTTP, only via HTTPS) and httpOnly (can't be read by Javascript) and talks to the server over an encrypted channel (HTTPS). Once you know you have a secure channel between the server and client you can securely exchange JWT or whatever else you want.

2. This keeps thing simple. A simple implementation makes adoption easier but it also lets each layer do what it does best (let HTTPS handle encryption).

3. JWT isn't meant to store sensitive data. Once the server receives the JWT token and validates it, it is free to lookup the user ID in its own database for additional information for that user (like permissions, postal address, etc). This keeps JWT small in size and avoids inadvertent information leakage because everyone knows not to keep sensitive data in JWT.

It's not too different from how cookies themselves work. Cookies often contain unencrypted payloads. If you are using HTTPS then everything is good. If you aren't then it's advisable to encrypt sensitive cookies themselves. Not doing so will mean that a man-in-the-middle attack is possible--a proxy server or ISP reads the cookies and then replays them later on pretending to be you. For similar reasons, JWT should always be exchanged over a secure layer like HTTPS.

Below you can find my implementation of gradient descent for linear regression problem.

At first, you calculate gradient like X.T * (X * w - y) / N and update your current theta with this gradient simultaneously.

• X: feature matrix
• y: target values
• w: weights/values
• N: size of training set

Here is the python code:

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import random

def generateSample(N, variance=100):
    X = np.matrix(range(N)).T + 1
    Y = np.matrix([random.random() * variance + i * 10 + 900 for i in range(len(X))]).T
    return X, Y

def fitModel_gradient(x, y):
    N = len(x)
    w = np.zeros((x.shape[1], 1))
    eta = 0.0001

    maxIteration = 100000
    for i in range(maxIteration):
        error = x * w - y
        gradient = x.T * error / N
        w = w - eta * gradient
    return w

def plotModel(x, y, w):
    plt.plot(x[:,1], y, "x")
    plt.plot(x[:,1], x * w, "r-")
    plt.show()

def test(N, variance, modelFunction):
    X, Y = generateSample(N, variance)
    X = np.hstack([np.matrix(np.ones(len(X))).T, X])
    w = modelFunction(X, Y)
    plotModel(X, Y, w)


test(50, 600, fitModel_gradient)
test(50, 1000, fitModel_gradient)
test(100, 200, fitModel_gradient)

I had this issue as well. My solution was to disable selinux. I tried allowing 2 different http settings in selinux (something like httpd_allow_email and http_can_connect) and that didn't work, so I just disabled it completely and it started working.

It could be due to the architecture of your OS. Is your OS 64 Bit and have you installed 64 bit version of Python? It may help to install both 32 bit version Python 3.1 and Pygame, which is available officially only in 32 bit and you won't face this problem.

I see that 64 bit pygame is maintained here, you might also want to try uninstalling Pygame only and install the 64 bit version on your existing python3.1, if not choose go for both 32-bit version.

There actually doesn't seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to give an indication on how the thread exited, 0 tends to mean that it exited safely whilst anything else tends to mean it didn't exit as expected. But then this exit code can be set in code by yourself to completely overlook this.

The closest link I could find to be useful for more information is this

Quote from above link:

What ever the method of exiting, the integer that you return from your process or thread must be values from 0-255(8bits). A zero value indicates success, while a non zero value indicates failure. Although, you can attempt to return any integer value as an exit code, only the lowest byte of the integer is returned from your process or thread as part of an exit code. The higher order bytes are used by the operating system to convey special information about the process. The exit code is very useful in batch/shell programs which conditionally execute other programs depending on the success or failure of one.

From the Documentation for GetEXitCodeThread

Important The GetExitCodeThread function returns a valid error code defined by the application only after the thread terminates. Therefore, an application should not use STILL_ACTIVE (259) as an error code. If a thread returns STILL_ACTIVE (259) as an error code, applications that test for this value could interpret it to mean that the thread is still running and continue to test for the completion of the thread after the thread has terminated, which could put the application into an infinite loop.

My understanding of all this is that the exit code doesn't matter all that much if you are using threads within your own application for your own application. The exception to this is possibly if you are running a couple of threads at the same time that have a dependency on each other. If there is a requirement for an outside source to read this error code, then you can set it to let other applications know the status of your thread.

I would suggest using the duplicated method on the Pandas Index itself:

df3 = df3[~df3.index.duplicated(keep='first')]

While all the other methods work, the currently accepted answer is by far the least performant for the provided example. Furthermore, while the groupby method is only slightly less performant, I find the duplicated method to be more readable.

Using the sample data provided:

>>> %timeit df3.reset_index().drop_duplicates(subset='index', keep='first').set_index('index')
1000 loops, best of 3: 1.54 ms per loop

>>> %timeit df3.groupby(df3.index).first()
1000 loops, best of 3: 580 µs per loop

>>> %timeit df3[~df3.index.duplicated(keep='first')]
1000 loops, best of 3: 307 µs per loop

Note that you can keep the last element by changing the keep argument to 'last'.

It should also be noted that this method works with MultiIndex as well (using df1 as specified in Paul's example):

>>> %timeit df1.groupby(level=df1.index.names).last()
1000 loops, best of 3: 771 µs per loop

>>> %timeit df1[~df1.index.duplicated(keep='last')]
1000 loops, best of 3: 365 µs per loop

Type "bash -x" on the command line before the name of the Bash script. For instance, to execute foo.sh, type:

bash -x foo.sh

For passing an enum by intent, you can convert enum into integer.

Ex:

public enum Num{A ,B}

Sending(enum to integer):

Num send = Num.A;
intent.putExtra("TEST", send.ordinal());

Receiving(integer to enum):

Num rev;
int temp = intent.getIntExtra("TEST", -1);
if(temp >= 0 && temp < Num.values().length)
    rev = Num.values()[temp];

For xml formatted with attributes...

data.xml:

<building_data>
<building address="some address" lat="28.902914" lng="-71.007235" />
<building address="some address" lat="48.892342" lng="-75.0423423" />
<building address="some address" lat="58.929753" lng="-79.1236987" />
</building_data>

php code:

$reader = new XMLReader();

if (!$reader->open("data.xml")) {
    die("Failed to open 'data.xml'");
}

while($reader->read()) {
  if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == 'building') {
    $address = $reader->getAttribute('address');
    $latitude = $reader->getAttribute('lat');
    $longitude = $reader->getAttribute('lng');
}

$reader->close();

This will remove the folders and files and leave the folder behind.

KeyPress is a higher level of abstraction than KeyDown (and KeyUp). KeyDown and KeyUp are hardware related: the actual action of a key on the keyboard. KeyPress is more "I received a character from the keyboard".

Since you are looking for adding space between elements you may need something as simple as a margin-left or padding-left. Here are examples of both http://jsfiddle.net/BGHqn/3/

This will add 10 pixels to the left of the paragraph element

p {
    margin-left: 10px;
 }

or if you just want some padding within your paragraph element

p {
    padding-left: 10px;
}

Wep, another way to achieve the same result. We use it for its readability.

Instead of doing this hard-to-read sentence:

Type listType = new TypeToken<ArrayList<YourClass>>(){}.getType();
List<YourClass> list = new Gson().fromJson(jsonArray, listType);

Create a empty class that extends a List of your object:

public class YourClassList extends ArrayList<YourClass> {}

And use it when parsing the JSON:

List<YourClass> list = new Gson().fromJson(jsonArray, YourClassList.class);

Working on a project that has a lot of modals calling other modals and a few HTML guys that might not know to initiate it everytime for each button. Came to a similar conclusion as @gmaggio, begrudgingly after going the long way around first.

EDIT: Now supports modals called via javascript.

EDIT: Opening a scrolling modal from another modal now works.

$(document).on('show.bs.modal', function (event) {
    if (!event.relatedTarget) {
        $('.modal').not(event.target).modal('hide');
    };
    if ($(event.relatedTarget).parents('.modal').length > 0) {
        $(event.relatedTarget).parents('.modal').modal('hide');
    };
});

$(document).on('shown.bs.modal', function (event) {
    if ($('body').hasClass('modal-open') == false) {
        $('body').addClass('modal-open');
    };
});

Just place the modal calling button in as normal, and if it is picked up to be inside a modal, it will close the current one first before opening the one specified in data-target. Note that relatedTarget is provided by Bootstrap.

I also added the following to smooth out the fading a bit: I am sure more can be done though.

.modal-backdrop.fade + .modal-backdrop.fade {
    transition: opacity 0.40s linear 0s;
}

Setting Tomcat to listen to port 80 is WRONG , for development the 8080 is a good port to use. For production use, just set up an apache that shall forward your requests to your tomcat. Here is a how to.

No Go doesn't have a ternary operator, using if/else syntax is the idiomatic way.

Why does Go not have the ?: operator?

There is no ternary testing operation in Go. You may use the following to achieve the same result:

if expr {
    n = trueVal
} else {
    n = falseVal
}

The reason ?: is absent from Go is that the language's designers had seen the operation used too often to create impenetrably complex expressions. The if-else form, although longer, is unquestionably clearer. A language needs only one conditional control flow construct.

In addition to the anwser of Bill the Lizard:

Most of the backends parse the raw post data. In PHP for example, you will have an array $_POST in which individual variables within the post data will be stored. In this case you have to use an additional header "Content-type: application/x-www-form-urlencoded":

Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
objHTTP.send ("var1=value1&var2=value2&var3=value3")

Otherwise you have to read the raw post data on the variable "$HTTP_RAW_POST_DATA".

This will do:

#include <fstream>

Handlebars now supports {{else if}} as of 3.0.0. Therefore, your code should now work.

You can see an example under "conditionals" (slightly revised here with an added {{else}}:

    {{#if isActive}}
      <img src="star.gif" alt="Active">
    {{else if isInactive}}
      <img src="cry.gif" alt="Inactive">
    {{else}}
      <img src="default.gif" alt="default">
    {{/if}}

2017 Update

1. Open Google API - https://console.developers.google.com
2. Go to Credentials.
3. Click on the 'Create Credentials' button. At time of writing it's currently a blue coloured dropdown.
4. Select API Key.

You should get a dialog from where you can copy this API key to use in your project. Hope this helps.

An abstract class cannot be instantiated by definition. In order to use this class, you must create a concrete subclass which implements all virtual functions of the class. In this case, you most likely have not implemented all the virtual functions declared in Light. This means that AmbientOccluder defaults to an abstract class. For us to further help you, you should include the details of the Light class.

The OP needed to cast as string outside the {% set ... %}. But if that not your case you can do:

{% set curYear = 2013 | string() %}

Note that you need the parenthesis on that jinja filter.

If you're concatenating 2 variables, you can also use the ~ custom operator.

The easiest way I found:

<Setter Property="Focusable" Value="false"/>

I have an Activity that extends ListActivity.

I tried doing something like this in onCreate:

ListView listView = getListView();
listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {

        Log.i("Hello!", "Y u no see me?");

    }

});

But that didn't work.

Instead I simply needed to override onListItemClick:

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {

    Log.i("Hello!", "Clicked! YAY!");

}

router.navigate vs router.navigateByUrl

router.navigate is just a convenience method that wraps router.navigateByUrl, it boils down to:

navigate(commands: any[], extras) {
    return router.navigateByUrl(router.createUrlTree(commands, extras), extras);
}

As mentioned in other answers router.navigateByUrl will only accept absolute URLs:

// This will work
router.navigateByUrl("http://localhost/team/33/user/11")
// This WON'T work even though relativeTo parameter is in the signature
router.navigateByUrl("../22", {relativeTo: route})

All the relative calculations are done by router.createUrlTree and router.navigate. Array syntax is used to treat every array element as a URL modifying "command". E.g. ".." - go up, "path" - go down, {expand: true} - add query param, etc.. You can use it like this:

// create /team/33/user/11
router.navigate(['/team', 33, 'user', 11]);

// assuming the current url is `/team/33/user/11` and the route points to `user/11`

// navigate to /team/33/user/11/details
router.navigate(['details'], {relativeTo: route});

// navigate to /team/33/user/22
router.navigate(['../22'], {relativeTo: route});

// navigate to /team/44/user/22
router.navigate(['../../team/44/user/22'], {relativeTo: route});

That {relativeTo: route} parameter is important as that's what router will use as the root for relative operations.

Get it through your component's constructor:

  // In my-awesome.component.ts:

  constructor(private route: ActivatedRoute, private router: Router) {}
  
  // Example call
  onNavigateClick() {
    // Navigates to a parent component
    this.router.navigate([..], { relativeTo: this.route })
  }

routerLink directive

Nicest thing about this directive is that it will retrieve the ActivatedRoute for you. Under the hood it's using already familiar:

router.navigateByUrl(router.createUrlTree(commands, { relativeTo: route }), { relativeTo: route });

Following variants will produce identical result:

[routerLink]="['../..']"

// if the string parameter is passed it will be wrapped into an array
routerLink="../.."

According to this official guide, you can add WindowManager.LayoutParams.FLAG_SECURE to your window layout and it will disallow screenshots.

You cannot "convert" an existing column into an IDENTITY column - you will have to create a new column as INT IDENTITY:

ALTER TABLE ProductInProduct 
ADD NewId INT IDENTITY (1, 1);

Update:

OK, so there is a way of converting an existing column to IDENTITY. If you absolutely need this - check out this response by Martin Smith with all the gory details.

Hibernate logging has to be also enabled in hibernate configuration.

Add lines

hibernate.show_sql=true
hibernate.format_sql=true

either to

server\default\deployers\ejb3.deployer\META-INF\jpa-deployers-jboss-beans.xml

or to application's persistence.xml in <persistence-unit><properties> tag.

Anyway hibernate logging won't include (in useful form) info on actual prepared statements' parameters.

There is an alternative way of using log4jdbc for any kind of sql logging.

The above answer assumes that you run the code that uses hibernate on JBoss, not in IDE. In this case you should configure logging also on JBoss in server\default\deploy\jboss-logging.xml, not in local IDE classpath.

Note that JBoss 6 doesn't use log4j by default. So adding log4j.properties to ear won't help. Just try to add to jboss-logging.xml:

   <logger category="org.hibernate">
     <level name="DEBUG"/>
   </logger>

Then change threshold for root logger. See SLF4J logger.debug() does not get logged in JBoss 6.

If you manage to debug hibernate queries right from IDE (without deployment), then you should have log4j.properties, log4j, slf4j-api and slf4j-log4j12 jars on classpath. See http://www.mkyong.com/hibernate/how-to-configure-log4j-in-hibernate-project/.

None of these answers solved the problem for me. The root cause being:

You cannot store 4-byte characters in MySQL with the utf-8 character set.

MySQL has a 3 byte limit on utf-8 characters (yes, it's wack, nicely summed up by a Django developer here)

To solve this you need to:

1. Change your MySQL database, table and columns to use the utf8mb4 character set (only available from MySQL 5.5 onwards)
2. Specify the charset in your Django settings file as below:

settings.py

DATABASES = {
    'default': {
        'ENGINE':'django.db.backends.mysql',
        ...
        'OPTIONS': {'charset': 'utf8mb4'},
    }
}

Note: When recreating your database you may run into the 'Specified key was too long' issue.

The most likely cause is a CharField which has a max_length of 255 and some kind of index on it (e.g. unique). Because utf8mb4 uses 33% more space than utf-8 you'll need to make these fields 33% smaller.

In this case, change the max_length from 255 to 191.

Alternatively you can edit your MySQL configuration to remove this restriction but not without some django hackery

UPDATE: I just ran into this issue again and ended up switching to PostgreSQL because I was unable to reduce my VARCHAR to 191 characters.

You can use the following in htaccess to allow and deny access to your site :

SetEnvIf remote_addr ^1\.2\3\.4\.5$ allowedip=1

Order deny,allow
deny from all
allow from env=allowedip

We first set an env variable allowedip if the client ip address matches the pattern, if the pattern matches then env variable allowedip is assigned the value 1 .

In the next step, we use Allow,deny directives to allow and deny access to the site. Order deny,allow represents the order of deny and allow . deny from all this line tells the server to deny everyone. the last line allow from env=allowedip allows access to a single ip address we set the env variable for.

Replace 1\.2\.3\.4\.5 with your allowed ip address.

Moq (and other DynamicProxy-based mocking frameworks) are unable to mock anything that is not a virtual or abstract method.

Sealed/static classes/methods can only be faked with Profiler API based tools, like Typemock (commercial) or Microsoft Moles (free, known as Fakes in Visual Studio 2012 Ultimate /2013 /2015).

Alternatively, you could refactor your design to abstract calls to static methods, and provide this abstraction to your class via dependency injection. Then you'd not only have a better design, it will be testable with free tools, like Moq.

A common pattern to allow testability can be applied without using any tools altogether. Consider the following method:

public class MyClass
{
    public string[] GetMyData(string fileName)
    {
        string[] data = FileUtil.ReadDataFromFile(fileName);
        return data;
    }
}

Instead of trying to mock FileUtil.ReadDataFromFile, you could wrap it in a protected virtual method, like this:

public class MyClass
{
    public string[] GetMyData(string fileName)
    {
        string[] data = GetDataFromFile(fileName);
        return data;
    }

    protected virtual string[] GetDataFromFile(string fileName)
    {
        return FileUtil.ReadDataFromFile(fileName);
    }
}

Then, in your unit test, derive from MyClass and call it TestableMyClass. Then you can override the GetDataFromFile method to return your own test data.

Hope that helps.

One option is http://davidbau.com/seedrandom which is a seedable RC4-based Math.random() drop-in replacement with nice properties.

Although answer is provided I found simpler solution:

Date:

01/20/2017

By doing replace

CurrentDate = replace(date, "/", "-")

It will output:

01-20-2017

Here is another way to do the same.

fadeIn effect

.visible {
  visibility: visible;
  opacity: 1;
  transition: opacity 2s linear;
}

fadeOut effect

.hidden {
  visibility: hidden;
  opacity: 0;
  transition: visibility 0s 2s, opacity 2s linear;
}

UPDATE 1: I found more up-to-date tutorial CSS3 Transition: fadeIn and fadeOut like effects to hide show elements and Tooltip Example: Show Hide Hint or Help Text using CSS3 Transition here with sample code.

UPDATE 2: (Added details requested by @big-money)

When showing the element (by switching to the visible class), we want the visibility:visible to kick in instantly, so it’s ok to transition only the opacity property. And when hiding the element (by switching to the hidden class), we want to delay the visibility:hidden declaration, so that we can see the fade-out transition first. We’re doing this by declaring a transition on the visibility property, with a 0s duration and a delay. You can see a detailed article here.

I know I am too late to answer but posting this answer to save others time. Hope it helps you!!

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

Instead of using local imports, you may import the entire module instead of the particular object. Then, in your app module, call mod_login.mod_login

app.py

from flask import Flask
import mod_login

# ...

do_stuff_with(mod_login.mod_login)

mod_login.py

from app import app

mod_login = something

From the Java interface design FAQ by Philip Shaw:

Interface variables are static because Java interfaces cannot be instantiated in their own right; the value of the variable must be assigned in a static context in which no instance exists. The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned by program code.

I see what you are trying to do, you are trying to use the <body> tag as the container for the main content of the page. Instead, use the <main> tag, as specified in the HTML5 spec. I use this layout:

    <!DOCTYPE html>
    <html>
        <head> *Metadata* </head>
        <body>
            <header>
                *<h1> and other important stuff </h1>*
                <nav> *Usually a formatted <Ul>* </nav>
            </header>
            <main> *All my content* </main>
            <footer> *Copyright, links, social media etc* </footer>
        </body>
    </html>

I'm not 100% sure but I think that anything outside the <body> tag is considered metadata and will not be rendered by the browser. I don't think that the DOM can access it either.

To conclude, use the <main> tag for your content and keep formatting your HTML the correct way as you have in your first code snippet. You used the <section> tag but I think that comes with some weird formatting issues when you try to apply CSS.

Hey! I'm the developer of wxMathPlot! The project is active: I just took a long time to get a new release, because the code needed a partial rewriting to introduce new features. Take a look to the new 0.1.0 release: it is a great improvement from old versions. Anyway, it doesn't provide 3D (even if I always thinking about it...).

If you want to clear all item you stored in localStorage then

localStorage.clear();

Use this for clear all stored key.

If you want to clear/remove only specific key/value then you can use removeItem(key).

localStorage.removeItem('yourKey');

The existing answers all seem to run this script in a DOS console window.

This may be acceptable, but for example means that colour codes (changing text colour) don't work but instead get printed out as they are:

there is no item "[032mGroovy[0m"

I found this solution some time ago, so I'm not sure whether mintty.exe is a standard Cygwin utility or whether you have to run the setup program to get it, but I run like this:

D:\apps\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico  bash.exe .\myShellScript.sh

... this causes the script to run in a Cygwin BASH console instead of a Windows DOS console.

In Kotlin extension function can be used. This can only be used from code, not xml.

fun TextView.underline() {
    paintFlags = paintFlags or Paint.UNDERLINE_TEXT_FLAG
}

Usage:

 tv_change_number.underline()
 tv_resend_otp.underline()

Use sprintf.

int sprintf ( char * str, const char * format, ... );

Write formatted data to string Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str.

The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version).

A terminating null character is automatically appended after the content.

After the format parameter, the function expects at least as many additional arguments as needed for format.

Parameters:

str

Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.

format

C string that contains a format string that follows the same specifications as format in printf (see printf for details).

... (additional arguments)

Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the number of values specified in the format specifiers. Additional arguments are ignored by the function.

Example:

// Allocates storage
char *hello_world = (char*)malloc(13 * sizeof(char));
// Prints "Hello world!" on hello_world
sprintf(hello_world, "%s %s!", "Hello", "world");

matches(); does not buffer, but find() buffers. find() searches to the end of the string first, indexes the result, and return the boolean value and corresponding index.

That is why when you have a code like

1:Pattern.compile("[a-z]");

2:Pattern.matcher("0a1b1c3d4");

3:int count = 0;

4:while(matcher.find()){

5:count++: }

At 4: The regex engine using the pattern structure will read through the whole of your code (index to index as specified by the regex[single character] to find at least one match. If such match is found, it will be indexed then the loop will execute based on the indexed result else if it didn't do ahead calculation like which matches(); does not. The while statement would never execute since the first character of the matched string is not an alphabet.

Another small point: If you used the import some_module as sm syntax, then you have to re-load the module with its aliased name (sm in this example):

>>> import some_module as sm
...
>>> import importlib
>>> importlib.reload(some_module) # raises "NameError: name 'some_module' is not defined"
>>> importlib.reload(sm) # works

This is working for me:

dataSource = new MatTableDataSource<Dict>([]);
    public search() {
        let url = `${Constants.API.COMMON}/dicts?page=${this.page.number}&` + 
        (this.name == '' ? '' : `name_like=${this.name}`);
    this._http.get<Dict>(url).subscribe((data)=> {
    // this.dataSource = data['_embedded'].dicts;
    this.dataSource.data =  data['_embedded'].dicts;
    this.page = data['page'];
    this.resetSelection();
  });
}

So you should declare your datasource instance as MatTableDataSource

You can call a function on click event of button.

<input type="button" class="btn btn-info" value="Input Button" onclick=" relocate_home()">

<script>
function relocate_home()
{
     location.href = "www.yoursite.com";
} 
</script>

OR Use this Code

<a href="#link" class="btn btn-info" role="button">Link Button</a>

I have come across exactly the same problem when trying to write a client for the National Rail SOAP service with Perl.

The problem was caused because the Perl module that I'm using 'SOAP::Lite' inserts a '#' in the SOAPAction header ...

SOAPAction: "http://thalesgroup.com/RTTI/2008-02-20/ldb/#GetDepartureBoard"

This is not interpreted correctly by .NET servers. I found this out from Example 3-19 in O'Reilly's Programming Web Services with SOAP . The solution was given below in section 3-20, namely you need to explicitly specify the format of the header with the 'on_action' method.

print SOAP::Lite
  -> uri('urn:Example1')
  -> on_action(sub{sprintf '%s/%s', @_ })
  -> proxy('http://localhost:8080/helloworld/example1.asmx')
  -> sayHello($name)
  -> result . "\n\n";

My guess is that soapclient.com is using SOAP::Lite behind the scenes and so are hitting the same problem when talking to National Rail.

The solution is to write your own client so that you have control over the format of the SOAPAction header ... but you've probably done that already.

You are missing a closing h2 tag. It should be:

<h2><!-- Content --></h2> 

Since Java 8 you can use Files#find method directly from java.nio.file.

public static Stream<Path> find(Path start,
                                int maxDepth,
                                BiPredicate<Path, BasicFileAttributes> matcher,
                                FileVisitOption... options)

Example usage

Files.find(startingPath,
           Integer.MAX_VALUE,
           (path, basicFileAttributes) -> path.toFile().getName().matches(".*.pom")
);

This vbscript/batch hybrid "append_sys_path.vbs" is not intuitive but works perfectly:

If CreateObject("WScript.Shell").Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
    CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & """", , "runas", 5
    WScript.Quit
End If
Set Shell = CreateObject("WScript.Shell")
Cmd = Shell.Exec("%ComSpec% /C ""REG QUERY ""HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"" /v Path | FINDSTR /I /C:""REG_SZ"" /C:""REG_EXPAND_SZ""""").StdOut.ReadAll
Cmd = """" & Trim(Replace(Mid(Cmd, InStr(1, Cmd, "_SZ", VBTextCompare) + 3), vbCrLf, ""))
If Right(Cmd, 1) <> ";" Then Cmd = Cmd & ";"
Cmd = "%ComSpec% /C ""REG ADD ""HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"" /v Path /t REG_EXPAND_SZ /d " & Replace(Cmd & "%SystemDrive%\Python27;%SystemDrive%\Python27\Scripts"" /f""", "%", """%""")
Shell.Run Cmd, 0, True

Advantages of this approach:

1) It doesn't truncate the system path environment at 1024 characters.
2) It doesn't concatenate the system and user path environment.
3) It's automatically run as administrator.
4) Preserve the percentages in the system path environment.
5) Supports spaces, parentheses and special characters.
6) Works on Windows 7 and above.

First method

For Windows 7 and above users, Windows PowerShell give you this option. Users with windows version less than 7 can download PowerShell online and install it.

Steps:

1. type PowerShell in search area and click on "Windows PowerShell"

2. If you have a .bat (batch) file go to step 3 OR copy your commands to a file and save it with .bat extension (e.g. file.bat)

3. run the .bat file with following command

   PS (location)> <path to bat file>/file.bat | Tee-Object -file log.txt

This will generate a log.txt file with all command prompt output in it. Advantage is that you can also the output on command prompt.

Second method

You can use file redirection (>, >>) as suggest by Bali C above.

I will recommend first method if you have lots of commands to run or a script to run. I will recommend last method if there is only few commands to run.

select u from UserGroup ug inner join ug.user u 
where ug.group_id = :groupId 
order by u.lastname

As a named query:

@NamedQuery(
  name = "User.findByGroupId",
  query =
    "SELECT u FROM UserGroup ug " +
    "INNER JOIN ug.user u WHERE ug.group_id = :groupId ORDER BY u.lastname"
)

Use paths in the HQL statement, from one entity to the other. See the Hibernate documentation on HQL and joins for details.

Both foo() and bar() may generate warnings in some IDEs. For example, IntelliJ IDEA will generate a Allocation of zero-length array warning.

An alternative approach is to use Apache Commons Lang 3 ArrayUtils.toArray() function with empty arguments:

public File[] bazz() {
    return ArrayUtils.toArray();
}

This approach is both performance and IDE friendly, yet requires a 3rd party dependency. However, if you already have commons-lang3 in your classpath, you could even use statically-defined empty arrays for primitive types:

public String[] bazz() {
    return ArrayUtils.EMPTY_STRING_ARRAY;
}

To delete all files and directories within the current directory:

find . -mtime +3 | xargs rm -Rf

Or alternatively, more in line with the OP's original command:

find . -mtime +3 -exec rm -Rf -- {} \;

Run command rndc querylog on or add querylog yes; to options{}; section in named.conf to activate that channel.

Also make sure you’re checking correct directory if your bind is chrooted.

Let's try to set the below properties in your xml for EditText

android:focusableInTouchMode="true" android:cursorVisible="false".

For a function type prop you can use the following code:

AddAddressComponent.defaultProps = {
    callBackHandler: () => {}
};

AddAddressComponent.propTypes = {
    callBackHandler: PropTypes.func,
};

There is no native IF/ELSE for CSS available. CSS preprocessors like SASS (and Compass) can help, but if you’re looking for more feature-specific if/else conditions you should give Modernizr a try. It does feature-detection and then adds classes to the HTML element to indicate which CSS3 & HTML5 features the browser supports and doesn’t support. You can then write very if/else-like CSS right in your CSS without any preprocessing, like this:

.geolocation #someElem {
   /* only apply this if the browser supports Geolocation */
}
.no-geolocation #someElem {
   /* only apply this if the browser DOES NOT support Geolocation */
}

Keep in mind that you should always progressively enhance, so rather than the above example (which illustrates the point better), you should write something more like this:

#someElem {
   /* default styles, suitable for both Geolocation support and lack thereof */
}
.geolocation #someElem {
   /* only properties as needed to overwrite the default styling  */
}

Note that Modernizr does rely on JavaScript, so if JS is disabled you wouldn’t get anything. Hence the progressive enhancement approach of #someElem first, as a no-js foundation.

for MacOS, make sure you know where the GO install

export GOPATH=/usr/local/go
PATH=$PATH:$GOPATH/bin

You can also use DEV_RANDOM, where 128 = 1/2 the generated token length. Code below generates 256 token.

$token = bin2hex(mcrypt_create_iv(128, MCRYPT_DEV_RANDOM));

Always Safe

In theory and by the specification, these are safe basically anywhere, except the domain name. Percent-encode anything not listed, and you're good to go.

    A-Z a-z 0-9 - . _ ~ ( ) ' ! * : @ , ;

Sometimes Safe

Only safe when used within specific URL components; use with care.

    Paths:     + & =
    Queries:   ? /
    Fragments: ? / # + & =
    

Never Safe

According to the URI specification (RFC 3986), all other characters must be percent-encoded. This includes:

    <space> <control-characters> <extended-ascii> <unicode>
    % < > [ ] { } | \ ^
    

If maximum compatibility is a concern, limit the character set to A-Z a-z 0-9 - _ . (with periods only for filename extensions).

Keep Context in Mind

Even if valid per the specification, a URL can still be "unsafe", depending on context. Such as a file:/// URL containing invalid filename characters, or a query component containing "?", "=", and "&" when not used as delimiters. Correct handling of these cases are generally up to your scripts and can be worked around, but it's something to keep in mind.

Adding to the answer given by @insomniac. You can create a Map to put the parameter for RequestBody including image.

Code for Interface

public interface ApiInterface {
@Multipart
@POST("/api/Accounts/editaccount")
Call<User> editUser (@Header("Authorization") String authorization, @PartMap Map<String, RequestBody> map);
}

Code for Java class

File file = new File(imageUri.getPath());
RequestBody fbody = RequestBody.create(MediaType.parse("image/*"), file);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), firstNameField.getText().toString());
RequestBody id = RequestBody.create(MediaType.parse("text/plain"), AZUtils.getUserId(this));

Map<String, RequestBody> map = new HashMap<>();
map.put("file\"; filename=\"pp.png\" ", fbody);
map.put("FirstName", name);
map.put("Id", id);
Call<User> call = client.editUser(AZUtils.getToken(this), map);
call.enqueue(new Callback<User>() {
@Override
public void onResponse(retrofit.Response<User> response, Retrofit retrofit) 
{
    AZUtils.printObject(response.body());
}

@Override
public void onFailure(Throwable t) {
    t.printStackTrace();
 }
});

1. Put your cursor at the begining of line 1.
2. click Edit>ColumnEditor. Put " in the text and hit enter.
3. Repeat 2 but put the cursor at the end of line1 and put ", and hit enter.

Your constructor may (later, in an extension of your software) be called from the constructor of a subclass that overrides the virtual method. Now not the subclass's implementation of the function, but the implementation of the base class will be called. So it doesn't really make sense to call a virtual function here.

However, if your design satisfies the Liskov Substitution principle, no harm will be done. Probably that's why it's tolerated - a warning, not an error.

On C# this works:

        if (DDLAlmacen.Items.Count > 0)
        {
            if (DDLAlmacen.Items.FindByValue("AlmacenDefectoAndes").Value == "AlmacenDefectoAndes")
            {
                DDLAlmacen.SelectedValue = "AlmacenDefectoAndes";
            }
        }

Update:

Translating the code above to Visual Basic doesn't work. It throws "System.NullReferenceException: Object reference not set to an instance of an object.."

So. for this to work on Visual Basic, I had to change the code like this:

        If DDLAlmacen.Items.Count > 0 Then
            If DDLAlmacen.Items.Contains(New ListItem("AlmacenDefectoAndes")) Then
                DDLAlmacen.SelectedValue = "AlmacenDefectoAndes"
            End If
        End If

You can use apache commons IOUtils to iterate through the line and append each line to StringBuilder. And don't forget to close the InputStream

StringBuilder sb = new StringBuilder();
FileInputStream fin=new FileInputStream("textfile.txt");
LineIterator lt=IOUtils.lineIterator(fin, "utf-8");
while(lt.hasNext())
{
  sb.append(lt.nextLine());
}
String text = sb.toString();
IOUtils.closeQuitely(fin);

Strangely, the answer is to keep adding back the property. I was half expecting a setter method. :S

System.out.println("Before: " + obj.get("DebugLogId")); // original "02352"

obj.addProperty("DebugLogId", "YYY");

System.out.println("After: " + obj.get("DebugLogId")); // now "YYY"

Try this:

$("#message span").text("hello world!");

See it in your code!

function Errormessage(txt) {
    var m = $("#message");

    // set text before displaying message
    m.children("span").text(txt);

    // bind close listener
    m.children("a.close-notify").click(function(){
      m.fadeOut("slow");
    });

    // display message
    m.fadeIn("slow");
}

ggID='put_googleID_here'  
ggURL='https://drive.google.com/uc?export=download'  
filename="$(curl -sc /tmp/gcokie "${ggURL}&id=${ggID}" | grep -o '="uc-name.*</span>' | sed 's/.*">//;s/<.a> .*//')"  
getcode="$(awk '/_warning_/ {print $NF}' /tmp/gcokie)"  
curl -Lb /tmp/gcokie "${ggURL}&confirm=${getcode}&id=${ggID}" -o "${filename}"  

How does it work?
Get cookie file and html code with curl.
Pipe html to grep and sed and search for file name.
Get confirm code from cookie file with awk.
Finally download file with cookie enabled, confirm code and filename.

curl -Lb /tmp/gcokie "https://drive.google.com/uc?export=download&confirm=Uq6r&id=0B5IRsLTwEO6CVXFURmpQZ1Jxc0U" -o "SomeBigFile.zip"

If you dont need filename variable curl can guess it
-L Follow redirects
-O Remote-name
-J Remote-header-name

curl -sc /tmp/gcokie "${ggURL}&id=${ggID}" >/dev/null  
getcode="$(awk '/_warning_/ {print $NF}' /tmp/gcokie)"  
curl -LOJb /tmp/gcokie "${ggURL}&confirm=${getcode}&id=${ggID}" 

To extract google file ID from URL you can use:

echo "gURL" | egrep -o '(\w|-){26,}'  
# match more than 26 word characters  

OR

echo "gURL" | sed 's/[^A-Za-z0-9_-]/\n/g' | sed -rn '/.{26}/p'  
# replace non-word characters with new line,   
# print only line with more than 26 word characters 

Additional Reason to use Foreign Keys: - Allows greater reuse of a database

Additional Reason to NOT use Foreign Keys: - You are trying to lock-in a customer into your tool by reducing reuse.

We just had the case here. It happened that the problem was the ownership of the corrupt file was root instead of our normal user. This was caused by a commit done on the server after someone has done a "sudo su --".

First, identify your corrupt file with:

$> git fsck --full

You should receive a answer like this one:

fatal: loose object 11b25a9d10b4144711bf616590e171a76a35c1f9 (stored in .git/objects/11/b25a9d10b4144711bf616590e171a76a35c1f9) is corrupt

Go in the folder where the corrupt file is and do a:

$> ls -la

Check the ownership of the corrupt file. If that's different, just go back to the root of your repo and do a:

$> sudo chown -R YOURCORRECTUSER:www-data .git/

Hope it helps!

Everybody is using the parse_url function, but sometimes user may pass the argumet in different format.

So as to fix that, I have created the function. Check this out:

function fixDomainName($url='')
{
    $strToLower = strtolower(trim($url));
    $httpPregReplace = preg_replace('/^http:\/\//i', '', $strToLower);
    $httpsPregReplace = preg_replace('/^https:\/\//i', '', $httpPregReplace);
    $wwwPregReplace = preg_replace('/^www\./i', '', $httpsPregReplace);
    $explodeToArray = explode('/', $wwwPregReplace);
    $finalDomainName = trim($explodeToArray[0]);
    return $finalDomainName;
}

Just pass the URL and get the domain.

For example,

echo fixDomainName('https://stackoverflow.com');

will return the result will be

stackoverflow.com

And in some situation:

echo fixDomainName('stackoverflow.com/questions/id/slug');

And it will also return stackoverflow.com.

Assuming that you have a collection ${roles} of the elements to put in the combo, and ${selected} the selected element, It would go like this:

<select name='role'>
    <option value="${selected}" selected>${selected}</option>
    <c:forEach items="${roles}" var="role">
        <c:if test="${role != selected}">
            <option value="${role}">${role}</option>
        </c:if>
    </c:forEach>
</select>

UPDATE (next question)

You are overwriting the attribute "productSubCategoryName". At the end of the for loop, the last productSubCategoryName.

Because of the limitations of the expression language, I think the best way to deal with this is to use a map:

Map<String,Boolean> map = new HashMap<String,Boolean>();
for(int i=0;i<userProductData.size();i++){
    String productSubCategoryName=userProductData.get(i).getProductSubCategory();
    System.out.println(productSubCategoryName);
    map.put(productSubCategoryName, true);
}
request.setAttribute("productSubCategoryMap", map);

And then in the JSP:

<select multiple="multiple" name="prodSKUs">
    <c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
        <option value="${productSubCategoryList}" ${not empty productSubCategoryMap[productSubCategoryList] ? 'selected' : ''}>${productSubCategoryList}</option>
    </c:forEach>
</select>

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

Without animation, you can use plain JS:

scroll(0,0)

With animation, check Nick's answer.

Like as @folone, but correct

private static List<Date> getDatesBetween(final Date date1, final Date date2) {
    List<Date> dates = new ArrayList<>();
    Calendar c1 = new GregorianCalendar();
    c1.setTime(date1);
    Calendar c2 = new GregorianCalendar();
    c2.setTime(date2);
    int a = c1.get(Calendar.DATE);
    int b = c2.get(Calendar.DATE);
    while ((c1.get(Calendar.YEAR) != c2.get(Calendar.YEAR)) || (c1.get(Calendar.MONTH) != c2.get(Calendar.MONTH)) || (c1.get(Calendar.DATE) != c2.get(Calendar.DATE))) {
        c1.add(Calendar.DATE, 1);
        dates.add(new Date(c1.getTimeInMillis()));
    }
    return dates;
}

In my case, HTTPS protocol was not supported by libcurl at the first place. To find out which protocols are supported and which are not, I checked the curl version using command:

curl --version

It provided information as follows: curl 7.50.3 (x86_64-apple-darwin15.6.0) libcurl/7.50.3 SecureTransport zlib/1.2.5 Protocols: dict file ftp ftps gopher http imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: IPv6 Largefile NTLM NTLM_WB SSL libz UnixSockets

where https protocol happens to be not supported.

Then I re-installed curl and installed it using the following commands(after unpacked):

./configure --with-darwinssl (enable ssl communication in mac) make make test sudo make install

And after several minutes of work, Problems resolved!

Then I re-run the curl version command, it showed:

curl 7.50.3 (x86_64-apple-darwin15.6.0) libcurl/7.50.3 SecureTransport zlib/1.2.5 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: IPv6 Largefile NTLM NTLM_WB SSL libz UnixSockets

HTTPS protocol showed up!

Finally, a useful site to refer when you run into curl problems. https://curl.haxx.se/docs/install.html

OK, there are just 2 different ways to do the same thing! One called object literal and the other one is a function constructor!

But read on, there are couple of things I'd like to share:

Using {} makes your code more readable, while creating instances of Object or other built-in functions not recommended...

Also, Object function gets parameters as it's a function, like Object(params)... but {} is pure way to start an object in JavaScript...

Using object literal makes your code looks much cleaner and easier to read for other developers and it's inline with best practices in JavaScript...

While Object in Javascript can be almost anything, {} only points to javascript objects, for the test how it works, do below in your javascript code or console:

var n = new Object(1); //Number {[[PrimitiveValue]]: 1}

Surprisingly, it's creating a Number!

var a = new Object([1,2,3]); //[1, 2, 3]

And this is creating a Array!

var s = new Object('alireza'); //String {0: "a", 1: "l", 2: "i", 3: "r", 4: "e", 5: "z", 6: "a", length: 7, [[PrimitiveValue]]: "alireza"}

and this weird result for String!

So if you are creating an object, it's recommended to use object literal, to have a standard code and avoid any code accident like above, also performance wise using {} is better in my experience!

Here, this ones working. :)

I had the exact same issue where jquery ajax only gave me cors issues on post requests where get requests worked fine - I tired everything above with no results. I had the correct headers in my server etc. Changing over to use XMLHTTPRequest instead of jquery fixed my issue immediately. No matter which version of jquery I used it didn't fix it. Fetch also works without issues if you don't need backward browser compatibility.

        var xhr = new XMLHttpRequest()
        xhr.open('POST', 'https://mywebsite.com', true)
        xhr.withCredentials = true
        xhr.onreadystatechange = function() {
          if (xhr.readyState === 2) {// do something}
        }
        xhr.setRequestHeader('Content-Type', 'application/json')
        xhr.send(json)

Hopefully this helps anyone else with the same issues.

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

Your for loop is wrong. Try :

for(int a = 0, b = 1; a<cards.length()-1; b=a+1, a++){

Also, System instead of system and == instead of ===.

But I'm not sure what you're trying to do.

setTimeout(function() { $location.path("/abc"); },0);

it should solve your problem.

It looks like your $pdo variable is not initialized. I can't see in the code you've uploaded where you are initializing it.

Make sure you create a new PDO object in the global scope before calling the class methods. (You should declare it in the global scope because of how you implemented the methods inside the Category class).

$pdo = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

Strangely, so many answers, and all of them are using surrogates like JS and keyboard shortcuts instead of just using a selenium feature:

def newTab(driver, url="about:blank"):
    wnd = driver.execute(selenium.webdriver.common.action_chains.Command.NEW_WINDOW)
    handle = wnd["value"]["handle"]
    driver.switch_to.window(handle)
    driver.get(url) # changes the handle
    return driver.current_window_handle

You can use List<T>.RemoveAt method:

rows.RemoveAt(rows.Count -1);

Use the power of Python and lean on one of the best libraries around: requests

import requests

r = requests.get('https://my.website.com/rest/path', auth=('myusername', 'mybasicpass'))
print(r.text)

Variable r (requests response) has a lot more parameters that you can use. Best thing is to pop into the interactive interpreter and play around with it, and/or read requests docs.

I did something simple, but it works.

I used a typical ToggleButton, which I restyled as a textblock by changing its control template. Then I just bound the IsChecked property on the ToggleButton to the IsOpen property on the popup. Popup has some properties like StaysOpen that let you modify the closing behavior.

The following works in XamlPad.

 <StackPanel>
  <ToggleButton Name="button"> 
    <ToggleButton.Template>
      <ControlTemplate TargetType="ToggleButton">
        <TextBlock>Click Me Here!!</TextBlock>
      </ControlTemplate>      
    </ToggleButton.Template>
  </ToggleButton>
  <Popup IsOpen="{Binding IsChecked, ElementName=button}" StaysOpen="False">
    <Border Background="LightYellow">
      <TextBlock>I'm the popup</TextBlock>
    </Border>
  </Popup> 
 </StackPanel>

Try css:

.topcorner{
    position:absolute;
    top:10px;
    right: 10px;
 }

you can play with the top and right properties.

If you want to float the div even when you scroll down, just change position:absolute; to position:fixed;.

Hope it helps.

Do you have Zend, IonCube, or xDebug installed? If so, that is probably where you are getting this error from.

I ran into this a few years ago, and it ended up being Zend putting that limit there, not PHP. Of course removing it will let you go past the 100 iterations, but you will eventually hit the memory limits.

One way or another you must tell boto3 in which region you wish the kms client to be created. This could be done explicitly using the region_name parameter as in:

kms = boto3.client('kms', region_name='us-west-2')

or you can have a default region associated with your profile in your ~/.aws/config file as in:

[default]
region=us-west-2

or you can use an environment variable as in:

export AWS_DEFAULT_REGION=us-west-2

but you do need to tell boto3 which region to use.

Try this:

SELECT Locations.Name, Schools.Name
FROM Locations
INNER JOIN School_Locations ON School_Locations.Locations_Id = Locations.Id
INNER JOIN Schools ON School.Id = Schools_Locations.School_Id
WHERE Locations.Type = "coun"

You can join Locations to School_Locations and then School_Locations to School. This forms a set of all related Locations and Schools, which you can then widdle down using the WHERE clause to those whose Location is of type "coun."

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Application_State_API

PUT http://{rm http address:port}/ws/v1/cluster/apps/{appid}/state

{
  "state":"KILLED"
}

If you don't mind including the underscore as an allowed character, you could try simply:

result = subject.replace(/\W+/g, "");

If the underscore must be excluded also, then

result = subject.replace(/[^A-Z0-9]+/ig, "");

(Note the case insensitive flag)

You set DockPanel.Dock="Top" to the StackPanel, but the StackPanel is not a child of the DockPanel... the Border is. Your docking property is being ignored.

If you move DockPanel.Dock="Top" to the Border instead, both of your problems will be fixed :)

Use IFNULL or COALESCE:

SELECT IFNULL(SUM(Column1), 0) AS total FROM...

SELECT COALESCE(SUM(Column1), 0) AS total FROM...

The difference between them is that IFNULL is a MySQL extension that takes two arguments, and COALESCE is a standard SQL function that can take one or more arguments. When you only have two arguments using IFNULL is slightly faster, though here the difference is insignificant since it is only called once.

Here is another way to solve your problem:

for (i in 1:nrow(trip)) {
  if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='T'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='A') {
    trip[i, 'mutType'] <- "G:C to T:A"
  }
  else if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='C'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='G') {
    trip[i, 'mutType'] <- "G:C to C:G"
  }
  else if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='A'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='T') {
    trip[i, 'mutType'] <- "G:C to A:T"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='T'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='A') {
    trip[i, 'mutType'] <- "A:T to T:A"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='G'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='C') {
    trip[i, 'mutType'] <- "A:T to G:C"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='C'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='G') {
    trip[i, 'mutType'] <- "A:T to C:G"
  }
}

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

Some Google services do not like to be used to much. Quite recently my account was locked because of script, which was sending two e-mails per second to the same user. Google considered it as a spam. So using sleep here is also justified to prevent such situations.

You should use ToList() method. (Don't forget about System.Linq namespace)

ex.:

IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();

To compare two git commits 12345 and abcdef as patches one can use the diff command as

diff <(git show 123456) <(git show abcdef)

I'm not sure why no one has suggested the following. This will get the auto_increment value using just SQL (no need for using PHP's mysql_fetch_array):

SELECT AUTO_INCREMENT FROM information_schema.tables WHERE TABLE_NAME = 'table'

You can use:

$(formId).serializeArray();

According Spring 4 MVC ResponseEntity.BodyBuilder and ResponseEntity Enhancements Example it could be written as:

....
   return ResponseEntity.ok().build();
....
   return ResponseEntity.noContent().build();

UPDATE:

If returned value is Optional there are convinient method, returned ok() or notFound():

return ResponseEntity.of(optional)

The --no-ff flag prevents git merge from executing a "fast-forward" if it detects that your current HEAD is an ancestor of the commit you're trying to merge. A fast-forward is when, instead of constructing a merge commit, git just moves your branch pointer to point at the incoming commit. This commonly occurs when doing a git pull without any local changes.

However, occasionally you want to prevent this behavior from happening, typically because you want to maintain a specific branch topology (e.g. you're merging in a topic branch and you want to ensure it looks that way when reading history). In order to do that, you can pass the --no-ff flag and git merge will always construct a merge instead of fast-forwarding.

Similarly, if you want to execute a git pull or use git merge in order to explicitly fast-forward, and you want to bail out if it can't fast-forward, then you can use the --ff-only flag. This way you can regularly do something like git pull --ff-only without thinking, and then if it errors out you can go back and decide if you want to merge or rebase.

This happened to me even on debug builds and just cleared all the module level and project level build folders and it worked, yeah just like that.

Use Collection#retainAll().

listA.retainAll(listB);
// listA now contains only the elements which are also contained in listB.

If you want to avoid that changes are being affected in listA, then you need to create a new one.

List<Integer> common = new ArrayList<Integer>(listA);
common.retainAll(listB);
// common now contains only the elements which are contained in listA and listB.

Building on Constantin's answer, here's the essence of what I learned while transitioning to Notepad++ as my primary HTML editor.

Install Notepad++ 32-bit

There's no 64-bit version of Tidy2 and some other popular plugins. The 32-bit version of NPP has few practical downsides, so axe the 64-bit version.

Install the Plugin Manager

Plugin Manager isn't strictly necessary for plugin usage. It does make things much easier, though.

Plugin Manager was eliminated from the core package apparently because the developer didn't like some included attribution linking.

You may notice that Plugin Manager plugin has been removed from the official distribution. The reason is Plugin Manager contains the advertising in its dialog. I hate Ads in applications, and I ensure you that there was no, and there will never be Ads in Notepad++.

It's a manual install, but it's not difficult.

1. Download the UNI (32-bit) zip package and extract it. Inside you'll see folders called plugins and updater. Each contains one file.
2. Drag those two files to the respective identically-named folders in your Notepad++ installation directory. Typically that's C:\Program Files (x86)\Notepad++.
3. Restart Notepad++ and follow any install/update prompts.

Now you'll see a new entry under Plugins for Plugin Manager.

Install Tidy2 (or your preferred alternative)

In Plugin Manager, check the box for Tidy2. Click Install. Restart when prompted.

To use Tidy2, select one of the preconfigured profiles in its Plugins submenu item, or create your own.

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

Using this function you can require a whole dir.

const GetAllModules = ( dirname ) => {
    if ( dirname ) {
        let dirItems = require( "fs" ).readdirSync( dirname );
        return dirItems.reduce( ( acc, value, index ) => {
            if ( PATH.extname( value ) == ".js" && value.toLowerCase() != "index.js" ) {
                let moduleName = value.replace( /.js/g, '' );
                acc[ moduleName ] = require( `${dirname}/${moduleName}` );
            }
            return acc;
        }, {} );
    }
}

// calling this function.

let dirModules = GetAllModules(__dirname);

The approach that I've taken has evolved since Java 1.0 to provide readability and maintain reasonable options for backward-compatibility with older Java versions, while also providing method signatures that are drop-in replacements for those from apache commons-lang. For performance reasons, I can see some possible objections to the use of Arrays.asList but I prefer helper methods that have sensible defaults without duplicating the one method that performs the actual work. This approach provides appropriate entry points to a reliable method that does not require array/list conversions prior to calling.

Possible variations for Java version compatibility include substituting StringBuffer (Java 1.0) for StringBuilder (Java 1.5), switching out the Java 1.5 iterator and removing the generic wildcard (Java 1.5) from the Collection (Java 1.2). If you want to take backward compatibility a step or two further, delete the methods that use Collection and move the logic into the array-based method.

public static String join(String[] values)
{
    return join(values, ',');
}

public static String join(String[] values, char delimiter)
{
    return join(Arrays.asList(values), String.valueOf(delimiter));
}

// To match Apache commons-lang: StringUtils.join(values, delimiter)
public static String join(String[] values, String delimiter)
{
    return join(Arrays.asList(values), delimiter);
}

public static String join(Collection<?> values)
{
    return join(values, ',');
}

public static String join(Collection<?> values, char delimiter)
{
    return join(values, String.valueOf(delimiter));
}

public static String join(Collection<?> values, String delimiter)
{
    if (values == null)
    {
        return new String();
    }

    StringBuffer strbuf = new StringBuffer();

    boolean first = true;

    for (Object value : values)
    {
        if (!first) { strbuf.append(delimiter); } else { first = false; }
        strbuf.append(value.toString());
    }

    return strbuf.toString();
}

In Intellij 13, it looks it's slightly different again. Here are the instructions for Intellij 13:

1. click on the Project view or unhide it by clicking on the "1: Project" button on the left border of the window or by pressing Alt + 1
2. find your project or sub-module and click on it to highlight it, then press F4, or right click and choose "Open Module Settings" (on IntelliJ 14 it became F12)
3. click on the dependencies tab
4. Click the "+" button on the right and select "Jars or directories..."
5. Find your path and click OK
6. In the dialog with "Choose Categories of Selected File", choose Classes (even if it's properties), press OK and OK again
7. You can now run your application and it will have the selected path in the class path

Javascript alternatives

Modernizr

Modernizr runs quickly on page load to detect features; it then creates a JavaScript object with the results, and adds classes to the html element

User agent selection

The Javascript:

var b = document.documentElement;
        b.setAttribute('data-useragent',  navigator.userAgent);
        b.setAttribute('data-platform', navigator.platform );
        b.className += ((!!('ontouchstart' in window) || !!('onmsgesturechange' in window))?' touch':'');

Adds (e.g) the below to the html element:

data-useragent='Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C)'
data-platform='Win32'

Allowing very targetted CSS selectors, e.g.:

html[data-useragent*='Chrome/13.0'] .nav{
    background:url(img/radial_grad.png) center bottom no-repeat;
}

Footnote

If possible, avoid browser targeting. Identify and fix any issue(s) you identify. Support progressive enhancement and graceful degradation. With that in mind, this is an 'ideal world' scenario not always obtainable in a production environment, as such- the above should help provide some good options.

Making local variables and method parameters final is essential if you want to pass those parameters into anonymous classes - like you instantiate an anonymous Thread and want to access those params in the body of the run() method.

Apart from that I am not sure of the performance benefits w.r.t better performance through compiler optimization. It is up to the specific compiler implementation whether it wants to optimize it at all...

It will be good to know of any performance stats from using final ...

I had 2 files (and 2 classes) in the same project with the same name.

Here is an even simplier way, by writing directly to php error output

curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_STDERR, fopen('php://stderr', 'w'));

Not proud of it, but:

def myMain(key):
    def ExecP1():
        pass
    def ExecP2():
        pass
    def ExecP3():
        pass
    def ExecPn():
        pass 
    locals()['Exec' + key]()

I do however recommend that you put those in a module/class whatever, this is truly horrible.

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

Sorting approach is not the best one. It takes O(n) space and O(nlogn) time. Instead, make a hash map of characters and count them (increment characters that appear in the first string and decrement characters that appear in the second string). When some count reaches zero, remove it from hash. Finally, if two strings are anagrams, then the hash table will be empty in the end - otherwise it will not be empty.

Couple of important notes: (1) Ignore letter case and (2) Ignore white space.

Here is the detailed analysis and implementation in C#: Testing If Two Strings are Anagrams

if the database is maintained by you then simply create a new database and import the data from the old one. the collation problem is solved!!!!!

in addition: for those who have a empty POST variable, don't use this:

name="[levels][level][]"

rather use this (as it is already here in this example):

name="levels[level][]"

You need to use the CSS white-space attribute.

In particular, white-space: nowrap and white-space: pre are the most commonly used values. The first one seems to be what you 're after.

You can use the Visual Viewport API:

window.visualViewport.scale;

It is standard and works both on desktop and mobile: browser support.

For enabling readonly:

$("#descrip").attr("readonly","true");

For disabling readonly

$("#descrip").attr("readonly","");

While the other answers are right, I prefer this way:

function ascii (a) { return a.charCodeAt(0); }

Then, to use it, simply:

var lineBreak = ascii("\n");

I am using this for a small shortcut system:

$(window).keypress(function(event) {
  if (event.ctrlKey && event.which == ascii("s")) {
    savecontent();
    }
  // ...
  });

And you can even use it inside map() or other methods:

var ints = 'ergtrer'.split('').map(ascii);

That's how I do it:

Since your have free choise about DB type use a filebased DB like e.g. firebird.

Create a template DB which has the schema that fits your actual branch and store it in your repository.

When executing your application programmatically create a copy of your template DB, store it somewhere else and just work with that copy.

This way you can put your DB schema under version control without the data. And if you change your schema you just have to change the template DB

Generally, I use null for values that I know can have a "null" state; for example

if(jane.isManager == false){
  jane.employees = null
}

Otherwise, if its a variable or function that's not defined yet (and thus, is not "usable" at the moment) but is supposed to be setup later, I usually leave it undefined.

Load testing = putting a specified amount of load on the server for certain amount of time. 100 simultaneous users for 10 minutes. Ensure stability of software. Stress testing = increasing the amount of load steadily until the software crashes. 10 simultaneous users increasing every 2 minutes until the server crashes.

To make a comparison to weight lifting: You "max" your weight to see what you can do for 1 rep (stress testing) and then on regular workouts you do 85% of your max value for 3 sets of 10 reps (load testing)

You can try to get the list of all elements with class = "content" by using find_elements_by_class_name:

a = driver.find_elements_by_class_name("content")

Then you can click on the link that you are looking for.

This can be achieved purely with JavaScript.

I see the answer I wanted to write has been answered by lynx in comments to the question.

But I'm going to write answer anyway because just like me, people sometimes forget to read the comments.

So, if you just want to get an element's distance (in Pixels) from the top of your screen window, here is what you need to do:

// Fetch the element
var el = document.getElementById("someElement");  

use getBoundingClientRect()

// Use the 'top' property of 'getBoundingClientRect()' to get the distance from top
var distanceFromTop = el.getBoundingClientRect().top; 

Thats it!

Hope this helps someone :)

We can use both std::advance as well as std::next, but there's a difference between the two.

advance modifies its argument and returns nothing. So it can be used as:

vector<int> v;
v.push_back(1);
v.push_back(2);
auto itr = v.begin();
advance(itr, 1);          //modifies the itr
cout << *itr<<endl        //prints 2

next returns a modified copy of the iterator:

vector<int> v;
v.push_back(1);
v.push_back(2);
cout << *next(v.begin(), 1) << endl;    //prints 2

This worked for me:

string string_test = "80123456";
unsigned long x;
signed long val;

std::stringstream ss;
ss << std::hex << string_test;
ss >> x;
// ss >> val;  // if I try this val = 0
val = (signed long)x;  // However, if I cast the unsigned result I get val = 0x80123456 

Agile is commonly regarded as an umbrella term. Scrum/Kanban are executions of Agile guiding principles from a project management perspective, whereas eXtreme Programming (XP) focuses on the engineering practices e.g., Unit Testing, Continuous Integration, Pair Programming etc.

Typically: Agile = Scrum + XP

Just put in the function using GLOBAL keyword:

 global $site_url;

Try this:

try
{
    throw new InvalidEmployeeTypeException();
    input.nextLine();
}
catch(InvalidEmployeeTypeException ex)
{
      //do error handling
}

continue;

If you run into this error in an IDE like Eclipse or IntelliJ, you may have one or more debug windows open and paused on a break-point. Terminate them.

occurrences = lambda s, lst: (i for i,e in enumerate(lst) if e == s)
list(occurrences(1, [1,2,3,1])) # = [0, 3]

While waiting for the adoption of CSS3 targeting…

While waiting for the adoption of CSS3 targeting by the major browsers, one could run the following sed command once the (X)HTML has been created:

sed -i 's|href="http|target="_blank" href="http|g' index.html

It will add target="_blank" to all external hyperlinks. Variations are also possible.

This is probably the simplest way:

data$rownumber = 1:dim(data)[1]

It's probably worth noting that if you want to select a row by its row index, you can do this with simple bracket notation

data[3,]

vs.

data[data$rownumber==3,]

So I'm not really sure what this new column accomplishes.

2017+ solution

The idea of function extensions comes from functional paradigm, which is natively supported since ES6:

function init(){
    doSomething();
}

// extend.js

init = (f => u => { f(u)
    doSomethingHereToo();
})(init);

init();

As per @TJCrowder's concern about stack dump, the browsers handle the situation much better today. If you save this code into test.html and run it, you get

test.html:3 Uncaught ReferenceError: doSomething is not defined
    at init (test.html:3)
    at test.html:8
    at test.html:12

Line 12: the init call, Line 8: the init extension, Line 3: the undefined doSomething() call.

Note: Much respect to veteran T.J. Crowder, who kindly answered my question many years ago, when I was a newbie. After the years, I still remember the respectfull attitude and I try to follow the good example.

The basic premise of the question and the answers are wrong. Every Select in a union can have a where clause. It's the ORDER BY in the first query that's giving yo the error.

According to current Backbone documentation....

view.remove()

Removes a view and its el from the DOM, and calls stopListening to remove any bound events that the view has listenTo'd.

I also use OleDbDataReader.IsDBNull()

if ( myReader.IsDBNull(colNum) ) { retrievedValue = ""; }
else { retrievedValue = myReader.GetString(colNum); }

Actually this is not a duplicate question. And this how i solve my problem after several times :

   int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());

This is the way to get offset from desired timezone.

Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.

   DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
                         DateTimeZone.forID("anytimezone"));

Now we will add our offset to the datetime, and get the timestamp from it.

    dt = dt.plusMillis(offset);
    Timestamp ts = new Timestamp(dt.getMillis());

May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.

You can use the runners token for CI/CD Pipelines of your GitLab repo.

git clone https://gitlab-ci-token:<runners token>@git.example.com/myuser/myrepo.git

Where <runners token> can be obtained from:

git.example.com/myuser/myrepo/pipelines/settings

or by clicking on the Settings icon -> CI/CD Pipeline and look for Runners Token on the page

Screenshot of the runners token location:

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

pandas.io.parsers.read_csv documentation

In my opinion this is great solution:

interface PersonRepository extends Repository<Person, UUID> {

    <T> Collection<T> findByLastname(String lastname, Class<T> type);
}

and using it like so

void someMethod(PersonRepository people) {

  Collection<Person> aggregates =
    people.findByLastname("Matthews", Person.class);

  Collection<NamesOnly> aggregates =
    people.findByLastname("Matthews", NamesOnly.class);
}

From ISO14882:2011(e) 5.6-4:

The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined. For integral operands the / operator yields the algebraic quotient with any fractional part discarded; if the quotient a/b is representable in the type of the result, (a/b)*b + a%b is equal to a.

The rest is basic math:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

Note that

If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.

from ISO14882:2003(e) is no longer present in ISO14882:2011(e)

Just set Null to ignore parameters that you don't want to use and then set the parameter needed according to the position.

 function myFunc($p1,$p2,$p3=Null,$p4=Null,$p5=Null,$p6=Null,$p7=Null,$p8=Null){
    for ($i=1; $i<9; $i++){
        $varName = "p$i";
        if (isset($$varName)){
            echo $varName." = ".$$varName."<br>\n";
        }
    }
}   

myFunc( "1", "2", Null, Null, Null, Null, Null, "eight" );

 <script>
    var storedSrcElements = [
         "js/exampleFile.js",
         "js/sampleFile.js",
         "css/style.css"
          ];

    var head= document.getElementsByTagName('head')[0];
    var script;
    var link;
    var versionNumberNew = 4.6;

    for(i=0;i<storedSrcElements.length;i++){
     script= document.createElement('script');
     script.type= 'text/javascript';
     script.src= storedSrcElements[i] + "?" + versionNumberNew;
     head.appendChild(script);
    }     


     </script> 


       ### Change the version number  (versionNumberNew) when you want the new files to be loaded  ###

Simple function, works with GET or POST. Plus you can assign a default value.

function GetPost($var,$default='') {
    return isset($_GET[$var]) ? $_GET[$var] : (isset($_POST[$var]) ? $_POST[$var] : $default);
}

Try This,

alter session set "_convert_set_to_join"= true;

The other alternative is to rewrite the SQL query manually [replacing the minus operator with a NOT IN subquery] evidences about 30% improvement in execution time .

 select * 
   from A 
    where (col1,col2,?) not in 
   (select col1,col2,? from B) 
   union all 
   select * from B 
  where (col1,col2,?) not in 
  (select col1,col2,? from A);

I think I found a simple solution to changing the collapse breakpoint, only through css.

I hope others can confirm it since I didn't test it thoroughly and I'm not sure if there are side effects to this solution.

You have to change the media query values for the following class definitions:

@media (min-width: BREAKPOINT px ){
    .navbar-toggle{display:none}
}

@media (min-width: BREAKPOINT px){
    .navbar-collapse{
        width:auto;
        border-top:0;box-shadow:none
    }
    .navbar-collapse.collapse{
        display:block!important;height:auto!important;padding-bottom:0;overflow:visible!important
    }
    .navbar-collapse.in{
        overflow-y:visible
   }
   .navbar-fixed-top .navbar-collapse,.navbar-static-top .navbar-collapse,.navbar-fixed-bottom .navbar-collapse{
        padding-left:0;padding-right:0
    }
}

This is what worked for me on my current project, but I still need to change some css definitions to arrange the menu properly for all screen sizes.

Hope this helps.

Eclipse Link, for many reasons, but notably I feel like it has less bloat than other main stream solutions (at least less in-your-face bloat).

Oh and Eclipse Link has been chosen to be the reference implementation for JPA 2.0

Another way is to handle the Runnable itself:

Runnable r = new Runnable {
    public void run() {
        if (booleanCancelMember != false) {
            //do what you need
        }
    }
}

A quicker faster version would use mt_rand:

$min=1;
$max=20;
echo mt_rand($min,$max);

Source: http://www.php.net/manual/en/function.mt-rand.php.

NOTE: Your server needs to have the Math PHP module enabled for this to work. If it doesn't, bug your host to enable it, or you have to use the normal (and slower) rand().

You create the collection in the Contact controller -

app/controllers/contacts_controller.erb 

Adding

@providers = Provider.all.by_name

to the new, create and edit methods, using a scope for the by_name in the Provider model - app/models/provider.rb - for the ordering by name

scope by_name  order(:name)

Then in the view - app/views/contacts/_form.html.erb - you use

<%= f.collection_select :provider_id, @providers, :id, :name, include_blank: true %>

For rails forms, I also strongly recommend you look at a form builder like simple_form - https://github.com/plataformatec/simple_form - which will do all the heavy lifting.

I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch, then remove them manually, but this will not work well if there are a lot.

Here is a solution that utilizes bash arrays to capture all files.

# Build bash array of the file names
while read -r file; do 
    rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)

git rm –-cached "${rmlist[@]}"

git commit -m 'ignore update'

I know this is a little old, but this but here is a concise function for counting regex patterns.

def regex_cnt(string, pattern):
    return len(re.findall(pattern, string))

string = 'abc123'

regex_cnt(string, '[0-9]')

I have a 2010 iMac with 8GB of RAM, running Eclipse Neon.2 Release (4.6.2) with Java 1.8.0_25. With the VM argument -Xmx6g, I ran the following code:

StringBuilder sb = new StringBuilder();
for (int i = 0; i < Integer.MAX_VALUE; i++) {
    try {
        sb.append('a');
    } catch (Throwable e) {
        System.out.println(i);
        break;
    }
}
System.out.println(sb.toString().length());

This prints:

Requested array size exceeds VM limit
1207959550

So, it seems that the max array size is ~1,207,959,549. Then I realized that we don't actually care if Java runs out of memory: we're just looking for the maximum array size (which seems to be a constant defined somewhere). So:

for (int i = 0; i < 1_000; i++) {
    try {
        char[] array = new char[Integer.MAX_VALUE - i];
        Arrays.fill(array, 'a');
        String string = new String(array);
        System.out.println(string.length());
    } catch (Throwable e) {
        System.out.println(e.getMessage());
        System.out.println("Last: " + (Integer.MAX_VALUE - i));
        System.out.println("Last: " + i);
    }
}

Which prints:

Requested array size exceeds VM limit
Last: 2147483647
Last: 0
Requested array size exceeds VM limit
Last: 2147483646
Last: 1
Java heap space
Last: 2147483645
Last: 2

So, it seems the max is Integer.MAX_VALUE - 2, or (2^31) - 3

P.S. I'm not sure why my StringBuilder maxed out at 1207959550 while my char[] maxed out at (2^31)-3. It seems that AbstractStringBuilder doubles the size of its internal char[] to grow it, so that probably causes the issue.

Top answer will not work in Jquery 1.9+ because of attr() method. Use prop() instead:

$(function() {
    $('#select_all').change(function(){
        var checkboxes = $(this).closest('form').find(':checkbox');
        if($(this).prop('checked')) {
          checkboxes.prop('checked', true);
        } else {
          checkboxes.prop('checked', false);
        }
    });
});

Solution by recursion

function count(arr, value) {
   if (arr.length === 1)    {
      return arr[0] === value ? 1 : 0;
   } else {
      return (arr.shift() === value ? 1 : 0) + count(arr, value);
   }
}

count([1,2,2,3,4,5,2], 2); // 3

This should solve your problem, you should try to run the following below:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser 

The most obvious solutions are already listed. Depending on where the query is sat (i.e. in application code) you can't always use IF statements and the inline CASE statements can get painful where lots of columns become conditional. Assuming Col1 + Col3 + Col7 are the same type, and likewise Col2, Col4 + Col8 you can do this:

SELECT Col1, Col2 FROM tbl WHERE @Var LIKE 'xyz'
UNION ALL
SELECT Col3, Col4 FROM tbl WHERE @Var LIKE 'zyx'
UNION ALL
SELECT Col7, Col8 FROM tbl WHERE @Var NOT LIKE 'xyz' AND @Var NOT LIKE 'zyx'

As this is a single command there are several performance benefits with regard to plan caching. Also the Query Optimiser will quickly eliminate those statements where @Var doesn't match the appropriate value without touching the storage engine.

Simply disable default browser behaviour using preventDefault and pass the event within your HTML.

<a href=/foo onclick= yes_js_login(event)>Lorem ipsum</a>

yes_js_login = function(e) {
  e.preventDefault();
}

For trimming your string, Go's "strings" package have TrimSpace(), Trim() function that trims leading and trailing spaces.

Check the documentation for more information.

There is no search and replace function or stream editing at the command line in XP or 2k3 (dont know about vista or beyond). So, you'll need to use a script like the one Ghostdog posted, or a search and replace capable tool like sed.

There is more than one way to do it, as this script shows:

@echo off
    SETLOCAL=ENABLEDELAYEDEXPANSION

    rename text.file text.tmp
    for /f %%a in (text.tmp) do (
        set foo=%%a
        if !foo!==ex3 set foo=ex5
        echo !foo! >> text.file) 
del text.tmp

This work for me

from flask import Flask
from flask import Response

app = Flask(__name__)

@app.route("/")
def home():
    return Response(headers={'Access-Control-Allow-Origin':'*'})

if __name__ == "__main__":
    app.run()

Yet another option in python 3:

re.sub(f'[^{re.escape(string.printable)}]', '', my_string)

I had this problem too. For me, the reason was that I was doing

return
commit

instead of

commit
return   

in one stored procedure.

IF you want to derive usg Boolean true False need to add "[]" around value

<form [formGroup]="form">
  <input type="radio" [value]=true formControlName="gender" >Male
  <input type="radio" [value]=false formControlName="gender">Female
</form>

You can choose only install the client during server install. The website only offers to let you download the full installer (grab whatever version you want from http://www.mysql.com/downloads/mysql/).

In the install wizard, when prompted for installation type (typical, minimal, custom), choose 'Custom'. On the next screen, select to NOT install the server, and proceed with the rest of the install as normal.

When you're done, you should see just the relevant client programs (mysql, mysqldump, etc) in C:\Program Files\MySQL..\bin

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

This worked for me.
