The reason for using POST when making changes to data:

• A web accelerator like Google Web Accelerator will click all (GET) links on a page and cache them. This is very bad if the links make changes to things.
• A browser caches GET requests so even if the user clicks the link it may not send a request to the server to execute the change.
• To protect your site/application against CSRF you must use POST. To completely secure your app you must then also generate a unique identifier on the server and send that along in the request.

Also, don't put sensitive information in the query string (only option with GET) because it shows up in the address bar, bookmarks and server logs.

Hopefully this explains why people say POST is 'secure'. If you are transmitting sensitive data you must use SSL.

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

A POST, unlike a GET, typically has relevant information in the body of the request. (A GET should not have a body, so aside from cookies, the only place to pass info is in the URL.) Besides keeping the URL relatively cleaner, POST also lets you send much more information (as URLs are limited in length, for all practical purposes), and lets you send just about any type of data (file upload forms, for example, can't use GET -- they have to use POST plus a special content type/encoding).

Aside from that, a POST connotes that the request will change something, and shouldn't be redone willy-nilly. That's why you sometimes see your browser asking you if you want to resubmit form data when you hit the "back" button.

GET, on the other hand, should be idempotent -- meaning you could do it a million times and the server will do the same thing (and show basically the same result) each and every time.

-X [your method]
X lets you override the default 'Get'

** corrected lowercase x to uppercase X

A very nice explanation is here-

https://blog.segunolalive.com/posts/restful-api-design-%E2%80%94-put-vs-patch/#:~:text=RFC%205789,not%20required%20to%20be%20idempotent.

A Normal Payload- // House on plot 1 { address: 'plot 1', owner: 'segun', type: 'duplex', color: 'green', rooms: '5', kitchens: '1', windows: 20 } PUT For Updated- // PUT request payload to update windows of House on plot 1 { address: 'plot 1', owner: 'segun', type: 'duplex', color: 'green', rooms: '5', kitchens: '1', windows: 21 } Note: In above payload we are trying to update windows from 20 to 21.

Now see the PATH payload- // Patch request payload to update windows on the House { windows: 21 }

Since PATCH is not idempotent, failed requests are not automatically re-attempted on the network. Also, if a PATCH request is made to a non-existent url e.g attempting to replace the front door of a non-existent building, it should simply fail without creating a new resource unlike PUT, which would create a new one using the payload. Come to think of it, it’ll be odd having a lone door at a house address.

The Symfony project tries to keep its HTTP methods joined up with CRUD methods, and their list associates them as follows:

• GET Retrieve the resource from the server
• POST Create a resource on the server
• PUT Update the resource on the server
• DELETE Delete the resource from the server

It's worth noting that, as they say on that page, "In reality, many modern browsers don't support the PUT and DELETE methods."

From what I remember, Symfony "fakes" PUT and DELETE for those browsers that don't support them when generating its forms, in order to try to be as close to using the theoretically-correct HTTP method even when a browser doesn't support it.

Swift uses the same cocoa-touch API. You can call all the same methods, but they will use Swift's syntax. In this example you can do something like this:

self.simpleLabel.text = "message"

Note the setText method isn't available. Setting the label's text with = will automatically call the setter in swift.

This has been possible since Java 7. The syntax for a multi-catch block is:

try { 
  ...
} catch (IllegalArgumentException | SecurityException | IllegalAccessException |
            NoSuchFieldException e) { 
  someCode();
}

Remember, though, that if all the exceptions belong to the same class hierarchy, you can simply catch that base exception type.

Also note that you cannot catch both ExceptionA and ExceptionB in the same block if ExceptionB is inherited, either directly or indirectly, from ExceptionA. The compiler will complain:

Alternatives in a multi-catch statement cannot be related by subclassing
  Alternative ExceptionB is a subclass of alternative ExceptionA

The fix for this is to only include the ancestor exception in the exception list, as it will also catch exceptions of the descendant type.

Had the same issue. Turns out I was using " instead of '.

use @import url('within single quotes'); like this

not @import url("within double quotes"); like this

That is how you define an anonymous function that gets called when the document is ready.

Razor is just a templating engine.

You should create a regular class.

If you want to make a method inside of a Razor page, put them in an @functions block.

Current Apache Commons Validator version is 1.3.1.

Class that validates is org.apache.commons.validator.EmailValidator. It has an import for org.apache.oro.text.perl.Perl5Util which is from a retired Jakarta ORO project.

BTW, I found that there is a 1.4 version, here are the API docs. On the site it says: "Last Published: 05 March 2008 | Version: 1.4-SNAPSHOT", but that's not final. Only way to build yourself (but this is a snapshot, not RELEASE) and use, or download from here. This means 1.4 has not been made final for three years (2008-2011). This is not in Apache's style. I'm looking for a better option, but didn't find one that is very adopted. I want to use something that is well tested, don't want to hit any bugs.

I ran into a similar issue a while back.

Your problem could be in two different areas. It's either how you're creating the file to write to, or your method of writing could be flawed in that it is phone dependent.

If you're writing the file to a specific location on the SD card, try using Environment variables. They should always point to a valid location. Here's an example to write to the downloads folder:

java.io.File xmlFile = new java.io.File(Environment
    .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
     + "/Filename.xml");

If you're writing the file to the application's internal storage. Try this example:

java.io.File xmlFile = new java.io.File((getActivity()
   .getApplicationContext().getFileStreamPath("FileName.xml")
   .getPath()));

Personally I rely on external libraries to handle the streaming to file. This one hasn't failed me yet.

org.apache.commons.io.FileUtils.copyInputStreamToFile(is, file);

I've lost data one too many times on a failed write command, so I rely on well-known and tested libraries for my IO heavy lifting.

If the files are large, you may also want to look into running the IO in the background, or use callbacks.

If you're already using environment variables, it could be a permissions issue. Check out Justin Fiedler's answer below.

Use generators?

def fib():
    a, b = 0, 1
    while True:
        yield a
        a, b = b, a + b

fibs = fib() #seems to be the only way to get the following line to work is to
             #assign the infinite generator to a variable

f = [fibs.next() for x in xrange(1001)]

for num in f:
        print num

above fib() function adapted from: http://intermediatepythonista.com/python-generators

If you are using a *nix system, why not leverage the system command?

import os
path = 'folder/to/clean'
os.system('rm -rf %s/*' % path)

You can use the following steps, its worked for me to drop table with constraint,solution already explained in the above comment, i just added screen shot for that -

While gcc 3.2.3 was more forgiving of the issue, gcc 4.1.2 is highlighting a potentially serious issue for the linking of your program later. Rather then trying to suppress the error you should make the forward declaration match the function declaration.

If you intended for the function to be globally available (as per the forward declaration) then don't subsequently declare it as static. Likewise if it's indented to be locally scoped then make the forward declaration static to match.

You should first submit your form and then change the value of your submit:

onClick="this.form.submit(); this.disabled=true; this.value='Sending…'; "

you can copy an individual text apart from an HTML element's text.

        var copyToClipboard = function (text) {
            var $txt = $('<textarea />');

            $txt.val(text)
                .css({ width: "1px", height: "1px" })
                .appendTo('body');

            $txt.select();

            if (document.execCommand('copy')) {
                $txt.remove();
            }
        };

I had this problem with WebDAV when hosting a MVC4 WebApi Project. I got around it by adding this line to the web.config:

<handlers>
  <remove name="WebDAV" />
  <add name="WebDAV" path="*" verb="*" modules="WebDAVModule"
      resourceType="Unspecified" requireAccess="None" />
</handlers>

As explained here: http://evolutionarydeveloper.blogspot.co.uk/2012/07/method-not-allowed-405-on-iis7-website.html

To complete some of the answers here, I had to get the ParametrizedType of MyGenericClass, no matter how high is the hierarchy, with the help of recursion:

private Class<T> getGenericTypeClass() {
        return (Class<T>) (getParametrizedType(getClass())).getActualTypeArguments()[0];
}

private static ParameterizedType getParametrizedType(Class clazz){
    if(clazz.getSuperclass().equals(MyGenericClass.class)){ // check that we are at the top of the hierarchy
        return (ParameterizedType) clazz.getGenericSuperclass();
    } else {
        return getParametrizedType(clazz.getSuperclass());
    }
}

Basically the Kernel is the interface between hardware (devices which are available in Computer) and Application software is like MS Office, Visual Studio, etc.

If I answer "what is an OS?" then the answer could be the same. Hence the kernel is the part & core of the OS.

The very sensitive tasks of an OS like memory management, I/O management, process management are taken care of by the kernel only.

So the ultimate difference is:

1. Kernel is responsible for Hardware level interactions at some specific range. But the OS is like hardware level interaction with full scope of computer.
2. Kernel triggers SystemCalls to tell the OS that this resource is available at this point of time. The OS is responsible to handle those system calls in order to utilize the resource.

if you remove the float: left from the a and add white-space: nowrap to the outer div

#myWorkContent{
    width:530px;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}
#myWorkContent a {
    display: inline;
}

this should work for any size or amount of images..

or even:

#myWorkContent a {
    display: inline-block;
    vertical-align: middle;
}

which would also vertically align images of different heights if required

Apple has added a new framework in iOS 11 called DeviceCheck which will help you to get the unique identifier very easily. Read this form more information. https://medium.com/@santoshbotre01/unique-identifier-for-the-ios-devices-590bb778290d

Hopefully this can help others: The above examples use ax.lines. With more recent mpl (3.3.1), there is ax.get_lines(). This bypasses the need for calling ax.lines=[]

for line in ax.get_lines(): # ax.lines:
    line.remove()
# ax.lines=[] # needed to complete removal when using ax.lines

If you want, you can deactivate this feature in your git core config using

git config core.autocrlf false

But it would be better to just get rid of the warnings using

git config core.autocrlf true

SOLUTION

<style>
.container {
    margin: 10px;
    width: 115px;
    height: 115px;
    line-height: 115px;
    text-align: center;
    border: 1px solid red;
    background-image: url("http://i.imgur.com/H9lpVkZ.jpg");
    background-repeat: no-repeat;
    background-position: center;
    background-size: contain;

}

</style>

<div class='container'>
</div>

<div class='container' style='width:50px;height:100px;line-height:100px'>
</div>

<div class='container' style='width:140px;height:70px;line-height:70px'>
</div>

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

I think Nokogiri gem is also a good choice. It is very stable and has a huge contributing community.

Samples:

a = Nokogiri::HTML.parse "foo bär"    
a.text 
=> "foo bär"

or

a = Nokogiri::HTML.parse "¡I'm highly annoyed with character references!"
a.text
=> "¡I'm highly annoyed with character references!"

You can specify multiple method signatures on the interface then have multiple method overloads on the class method:

interface INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter: number);
}

class MyNotificationService implements INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter?: number);
    error(message: string, param1?: (string|number), param2?: number) {
        var autoHideAfter: number,
            title: string;

        // example of mapping the parameters
        if (param2 != null) {
            autoHideAfter = param2;
            title = <string> param1;
        }
        else if (param1 != null) {
            if (typeof param1 === "string") {
                title = param1;
            }
            else {
                autoHideAfter = param1;
            }
        }

        // use message, autoHideAfter, and title here
    }
}

Now all these will work:

var service: INotificationService = new MyNotificationService();
service.error("My message");
service.error("My message", 1000);
service.error("My message", "My title");
service.error("My message", "My title", 1000);

...and the error method of INotificationService will have the following options:

Playground

It's also useful for splitting ranges; range(a,b) can be split into range(a, x) and range(x, b), whereas with inclusive range you would write either x-1 or x+1. While you rarely need to split ranges, you do tend to split lists quite often, which is one of the reasons slicing a list l[a:b] includes the a-th element but not the b-th. Then range having the same property makes it nicely consistent.

You have to create your own ControlTemplate for the Button. just have a look at the sample

created a style called RoundCorner and inside that i changed rather created my own new Control Template with Border (CornerRadius=8) for round corner and some background and other trigger effect. If you have or know Expression Blend it can be done very easily.

<Style x:Key="RoundCorner" TargetType="{x:Type Button}">
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Padding" Value="1"/>
    <Setter Property="Template">

Using

<Button Style="{DynamicResource RoundCorner}" 
        Height="25" 
        VerticalAlignment="Top" 
        Content="Show" 
        Width="100" 
        Margin="5" />

You can also try <C-x><C-l> which will repeat the last line from insert mode and brings you a completion window with all of the lines. It works almost like <C-p>

For angular 5+ version. Putting version helps as angular makes lot of changes.

ngOnInit() {

 this.myForm = formBuilder.group({
      firstName: 'Thomas',
      lastName: 'Mann'
    })
this.formControlValueChanged() // Note if you are doing an edit/fetching data from an observer this must be called only after your form is properly initialized otherwise you will get error.
}

formControlValueChanged(): void {       
        this.myForm.valueChanges.subscribe(value => {
            console.log('value changed', value)
        })
}

just use a property

int  _theVariable;
public int TheVariable{
  get{return _theVariable;}
  set{
    _theVariable = value; 
    if ( _theVariable == 1){
      //Do stuff here.
    }
  }
}

If you're running virtualenv:

virtualenv --clear </path/to/your/virtualenv>

for example, if your virtualenv is /Users/you/.virtualenvs/projectx, then you'd run:

virtualenv --clear /Users/you/.virtualenvs/projectx

if you don't know where your virtual env is located, you can run which python from within an activated virtual env to get the path

Try creating another SQL view instead of a temporary table and then referencing it in the main SQL view. In other words, a view within a view. You can then drop the first view once you are done creating the main view.

class Program
{
    static void Main(string[] args)
    {

        int transactionDate = 20201010;
        int? transactionTime = 210000;

        var agreementDate = DateTime.Today;
        var previousDate = agreementDate.AddDays(-1);

        var agreementHour = 22;
        var agreementMinute = 0;
        var agreementSecond = 0;

        var endDate = new DateTime(agreementDate.Year, agreementDate.Month, agreementDate.Day, agreementHour, agreementMinute, agreementSecond);

        DateTime selectedDate = Convert.ToDateTime(transactionDate.ToString().Substring(6, 2) + "/" + transactionDate.ToString().Substring(4, 2) + "/" + transactionDate.ToString().Substring(0, 4) + " " + string.Format("{0:00:00:00}", transactionTime));

        Console.WriteLine("End Date : " + endDate.ToString());

        if (selectedDate > startDate && selectedDate <= endDate)
            Console.WriteLine("Between two dates..");
        else if (selectedDate <= startDate)
            Console.WriteLine("Less than or equal to the start date!");
        else if (selectedDate > endDate)
            Console.WriteLine("Greater than end date!");
        else
            Console.WriteLine("Out of date ranges!");
    }
}

Quite late to this party, today I had the same problem. The right answer on macOs I think is use jenv

brew install jenv openjdk@11
jenv add /usr/local/opt/openjdk@11

And then add into Intellij IDEA as new SDK the following path:

~/.jenv/versions/11/libexec/openjdk.jdk/Contents/Home/

A better alternative to MinGW is bash for powershell. You can install bash for Windows 10 using the steps given here

After you've installed bash, all you've got to do is run the bash command on your terminal.

PS F:\cpp> bash
user@HP:/mnt/f/cpp$ g++ program.cpp -o program
user@HP:/mnt/f/cpp$ ./program

These are the shift operators

x << y Returns x with the bits shifted to the left by y places (and new bits on the right-hand-side are zeros). This is the same as multiplying x by 2**y.

x >> y Returns x with the bits shifted to the right by y places. This is the same as //'ing x by 2**y.

One more option is to ask MySQL for the query plan. This tells you two things:

• Whether there are any syntax errors in the query, if so the query plan command itself will fail
• How MySQL is planning to execute the query, e.g. what indexes it will use

In MySQL and most SQL databases the query plan command is describe, so you would do:

describe update ...;

TO 'user'@'%'

% is a wildcard - you can also do '%.domain.com' or '%.123.123.123' and things like that if you need.

for ((i = 0 ; i < max ; i++ )); do echo "$i"; done

Another polyfill for element.classList is here. I found it via MDN.

I include that script and use element.classList.add("first","second","third") as it's intended.

This command,

numpy.append(a, a[0])

does not alter a array. However, it returns a new modified array. So, if a modification is required, then the following must be used.

a = numpy.append(a, a[0])

There is not much information on the nature of the problem and the data, so difficult to advise. However, would recommend to assess the feasibility of other solutions, that can be easier to integrate with java and enables horizontal as well as vertical scaling. The first I would suggest to look at is an open source analytical engine called Apache Spark https://spark.apache.org/ that is available on Microsoft Azure but probably on other cloud IaaS providers too. If you stick to involving your GPU then the suggestion is to look at other GPU supported analytical databases on the market that fits in the budget of your organisation.

The "+1 month" issue with strtotime

As noted in several blogs, strtotime() solves the "+1 month" ("next month") issue on days that do not exist in the subsequent month differently than other implementations like for example MySQL.

$dt = date("Y-m-d");
echo date( "Y-m-d", strtotime( "$dt +1 day" ) ); // PHP:  2009-03-04
echo date( "Y-m-d", strtotime( "2009-01-31 +2 month" ) ); // PHP:  2009-03-31

What I really wanted was a GUI to reorder them and output them as one file

Playlist Producer does exactly that, decoding and reencoding them into a combined MP3. It's designed for creating mix tapes or simple podcasts, but you might find it useful.

(Disclosure: I wrote the software, and I profit if you buy the Pro Edition. The Lite edition is a free version with a few limitations).

A quick Update, for the text "Today", the right names are:

todayText: 'Huidige', todayStatus: 'Bekijk de huidige maand',

I know it's old, but I do think this solution is interesting if you don't care about the property order:

function objectsDeeplyEqual(obj1, obj2) {_x000D_
  const keys1 = Object.keys(obj1);_x000D_
  const keys2 = Object.keys(obj2);_x000D_
  let equal = true;_x000D_
  if (keys1.length !== keys2.length) {_x000D_
    return false;_x000D_
  }_x000D_
  for (let i = 0; i < keys1.length && equal; i++) {_x000D_
    if (obj1[keys1[i]] instanceof Object && obj2[keys1[i]] instanceof Object) {_x000D_
      equal = equal && isDeeplyEqual(obj1[keys1[i]], obj2[keys1[i]]);_x000D_
    } else {_x000D_
      equal = equal && obj1[keys1[i]] === obj2[keys1[i]];_x000D_
    }_x000D_
  }_x000D_
  return equal;_x000D_
}_x000D_
_x000D_
var a = {_x000D_
  a: true,_x000D_
  b: 'asd',_x000D_
  c: {_x000D_
    a: true,_x000D_
    b: 'asd',_x000D_
    c: {_x000D_
      a: true,_x000D_
      b: 'asd',_x000D_
    },_x000D_
  },_x000D_
};_x000D_
_x000D_
var b = {_x000D_
  a: true,_x000D_
  c: {_x000D_
    a: true,_x000D_
    b: 'asd',_x000D_
    c: {_x000D_
      a: true,_x000D_
      b: 'asd',_x000D_
    },_x000D_
  },_x000D_
  b: 'asd',_x000D_
};_x000D_
_x000D_
console.log(isDeeplyEqual(a,b));_x000D_
console.log(isDeeplyEqual(b,a));

Yes, when you invoke e.extractAll(foo), Python munges that into extractAll(e, foo).

From http://docs.python.org/tutorial/classes.html

the special thing about methods is that the object is passed as the first argument of the function. In our example, the call x.f() is exactly equivalent to MyClass.f(x). In general, calling a method with a list of n arguments is equivalent to calling the corresponding function with an argument list that is created by inserting the method’s object before the first argument.

Emphasis added.

Of course, never fails. Found the solution about a minute after posting the above question... solution for those that may have had the same issue:

ContextWrapper.getFilesDir()

Found here.

I wanted the date to be shown in the type='time' field.

The normal conversion skips the zeros and the form field does not show the value and puts forth an error in the console saying the format needs to be yyyy-mm-dd.

Hence I added a small statement (check)?(true):(false) as follows:

makeShortDate=(date)=>{
yy=date.getFullYear()
mm=date.getMonth()
dd=date.getDate()
shortDate=`${yy}-${(mm<10)?0:''}${mm+1}-${(dd<10)?0:''}${dd}`;
return shortDate;
}

Add disabled="disabled" in input and while jquery remove the attribute disabled when you want to submit it using .removeAttr('disabled')

HTML:

<input type="hidden" name="test" value="test" disabled='disabled'/>

jquery:

$("input[name='test']").removeAttr('disabled');

Don't use add for strings, you should define a custom tag like this :

Create a file : <appname>\templatetags\<appname>_extras.py

from django import template

register = template.Library()

@register.filter
def addstr(arg1, arg2):
    """concatenate arg1 & arg2"""
    return str(arg1) + str(arg2)

and then use it as @Steven says

{% load <appname>_extras %}

{% with "shop/"|addstr:shop_name|addstr:"/base.html" as template %}
    {% include template %}
{% endwith %}

Reason for avoiding add:

According to the docs

This filter will first try to coerce both values to integers... Strings that can be coerced to integers will be summed, not concatenated...

If both variables happen to be integers, the result would be unexpected.

Use defaultdict instead:

from collections import defaultdict
data = defaultdict(list)
data[1].append('hello')

This way you don't have to initialize all the keys you want to use to lists beforehand.

What is happening in your example is that you use one (mutable) list:

alist = [1]
data = dict.fromkeys(range(2), alist)
alist.append(2)
print data

would output {0: [1, 2], 1: [1, 2]}.

I just did the following (in V 3.5) and it worked like a charm:

<p:column headerText="name" width="20px"/>

Since I'm using openjdk managed with sdkman, I added

sudo ln -sfn /path/to/my/installed/jdk/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Adding this to your system lets java_home recognize your installed version of Java even when its not installed via standard packages

I'm too newbie to comment zeantsoi post ;(. So here his what I needed to do to solved on OSX on 10.9.1 the

IOError: decoder jpeg not available

1) install Xcode tools (open your terminal and execute: xcode-select --install) - taken from this post: Can't install PIL after Mac OS X 10.9

2) install libpng and libjpeg package (combo installer) from this link: http://ethan.tira-thompson.com/Mac_OS_X_Ports.html

3) reboot (not sure it was mandatory)

4) Re-install PIL with run pip install -I PIL (as I had initially installed PIL before having the issue)

Hope this help and don't confuse more ...

The other way to move introduced work from one branch to another is to cherry-pick it. A cherry-pick in Git is like a rebase for a single commit. It takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on. This is useful if you have a number of commits on a topic branch and you want to integrate only one of them, or if you only have one commit on a topic branch and you’d prefer to cherry-pick it rather than run rebase. For example, suppose you have a project that looks like this:

If you want to pull commit e43a6 into your master branch, you can run

$ git cherry-pick e43a6
Finished one cherry-pick.
[master]: created a0a41a9: "More friendly message when locking the index fails."
 3 files changed, 17 insertions(+), 3 deletions(-)

This pulls the same change introduced in e43a6, but you get a new commit SHA-1 value, because the date applied is different. Now your history looks like this:

Now you can remove your topic branch and drop the commits you didn’t want to pull in.

Here's a project that combines the best parts (pros) of both redux-saga and redux-thunk: you can handle all side-effects on sagas while getting a promise by dispatching the corresponding action: https://github.com/diegohaz/redux-saga-thunk

class MyComponent extends React.Component {
  componentWillMount() {
    // `doSomething` dispatches an action which is handled by some saga
    this.props.doSomething().then((detail) => {
      console.log('Yaay!', detail)
    }).catch((error) => {
      console.log('Oops!', error)
    })
  }
}

You are not specified your project as right way.

• So run your XAMPP control panel then start the apache and MySQL
• Then note the ports.
• For Example PORT 80: then you type your browser url as localhost:80\ press enter now your php basic Config page is visible.
• Then create any folder on xampp\htdocs\YourFloderName Then create php file then save it and go to browser then type it localhost\YourFolderName now it listed the files click the file and it runs.

For newer pandas versions

df.index = df.index.rename('new name')

or

df.index.rename('new name', inplace=True)

The latter is required if a data frame should retain all its properties.

Play is pretty sweet.

It is now production ready. It incorporates: a cool template framework,automatic reloading of source files upon safe, a composable action system, akka awesomeness, etc.

Its part of the Typesafe Stack.

Having used it for two projects, I can say that it works pretty smoothly and it should be something to consider next time you are looking to learn new web frameworks.

See that your statements refer to "elements of the DOM", which are things such as the HTML tags (A, INPUT, etc). Thse statements simply mean that multiple CSS classes may be assigned to one such element.

It will just sleep the thread except in the case where your application has only a single thread, in which case it will sleep the thread and effectively the process as well.

The python documentation on sleep doesn't specify this however, so I can certainly understand the confusion!

The python timedelta library should do what you need. A timedelta is returned when you subtract two datetime instances.

import datetime
dt_started = datetime.datetime.utcnow()

# do some stuff

dt_ended = datetime.datetime.utcnow()
print((dt_ended - dt_started).total_seconds())

To Write

Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",2,true)
objFileToWrite.WriteLine(data)
objFileToWrite.Close
Set objFileToWrite = Nothing

OpenTextFile parameters:

<filename>, IOMode (1=Read,2=write,8=Append), Create (true,false), Format (-2=System Default,-1=Unicode,0=ASCII)

To Read the entire file

Set objFileToRead = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",1)
strFileText = objFileToRead.ReadAll()
objFileToRead.Close
Set objFileToRead = Nothing

To Read line by line

Set objFileToRead = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",1)
Dim strLine
do while not objFileToRead.AtEndOfStream
     strLine = objFileToRead.ReadLine()
     'Do something with the line
loop
objFileToRead.Close
Set objFileToRead = Nothing

The accepted answer is out of date. Some of the suggestions were already incorporated in the package, and I was still getting the error about missing config-win.h & mysqlclient.lib.

• Install mysql-connector-c-6.0.2-win32.msi

  There's a zip file for the conenctor too but that didn't work because mysqlclient.lib is in lib directory whereas the installer expects it in lib/opt. Instead of hacking site.cfg or setup_windows.py, the msi does the job.

• pip install mysql-python

P.S. Since I don't use MySQL anymore, my answer may be out of date as well.

Import the file into Excel by first opening excel, then going to DATA, import from TXT File, choose the csv extension which will preserve 0 prefixed values, and save that column as TEXT because excel will drop the leading 0 otherwise (DO NOT double click to open with Excel if you have numeric data in a field starting with a 0 [zero]). Then just save out as a Tab Delimited Text file. When you are importing into excel you get an option to save as GENERAL, TEXT, etc.. choose TEXT so that quotes in the middle of a string in a field like YourCompany,LLC are preserved also...

BULK INSERT dbo.YourTableName
FROM 'C:\Users\Steve\Downloads\yourfiletoIMPORT.txt'
WITH (
FirstRow = 2, (if skipping a header row)
FIELDTERMINATOR = '\t',
ROWTERMINATOR   = '\n'
)

I wish I could use the FORMAT and Fieldquote functionality but that does not appear to be supported in my version of SSMS

Yes, you can use numpy for that.

import numpy as np
a = arange(3,dtype=float)

a[0] = np.nan
a[1] = np.inf
a[2] = -np.inf

a # is now [nan,inf,-inf]

np.isnan(a[0]) # True
np.isinf(a[1]) # True
np.isinf(a[2]) # True

Razor is a view engine for ASP.NET MVC, and also a template engine. Razor code and ASP.NET inline code (code mixed with markup) both get compiled first and get turned into a temporary assembly before being executed. Thus, just like C# and VB.NET both compile to IL which makes them interchangable, Razor and Inline code are both interchangable.

Therefore, it's more a matter of style and interest. I'm more comfortable with razor, rather than ASP.NET inline code, that is, I prefer Razor (cshtml) pages to .aspx pages.

Imagine that you want to get a Human class, and render it. In cshtml files you write:

<div>Name is @Model.Name</div>

While in aspx files you write:

<div>Name is <%= Human.Name %></div>

As you can see, @ sign of razor makes mixing code and markup much easier.

I am using a custom static class which makes- shows and hides a dialog. this class is being used by other activities too not only one activiy. Now the problem you described also appeared to me and i have stayed overnight to find a solution..

Finally i present you the solution!

if you want to show or dismiss a dialog and you dont know which activity initiated the dialog in order to touch it then the following code is for you..

 static class CustomDialog{

     public static void initDialog(){
         ...
         //init code
         ...
     }

      public static void showDialog(){
         ...
         //init code for show dialog
         ...
     }

     /****This is your Dismiss dialog code :D*******/
     public static void dismissProgressDialog(Context context) {                
            //Can't touch other View of other Activiy..
            //http://stackoverflow.com/questions/23458162/dismiss-progress-dialog-in-another-activity-android
            if ( (progressdialog != null) && progressdialog.isShowing()) {

                //is it the same context from the caller ?
                Log.w("ProgressDIalog dismiss", "the dialog is from"+progressdialog.getContext());

                Class caller_context= context.getClass();
                Activity call_Act = (Activity)context;
                Class progress_context= progressdialog.getContext().getClass();

                Boolean is_act= ( (progressdialog.getContext()) instanceof  Activity )?true:false;
                Boolean is_ctw= ( (progressdialog.getContext()) instanceof  ContextThemeWrapper )?true:false;

                if (is_ctw) {
                    ContextThemeWrapper cthw=(ContextThemeWrapper) progressdialog.getContext();
                    Boolean is_same_acivity_with_Caller= ((Activity)(cthw).getBaseContext() ==  call_Act )?true:false;

                    if (is_same_acivity_with_Caller){
                        progressdialog.dismiss();
                        progressdialog = null;
                    }
                    else {
                        Log.e("ProgressDIalog dismiss", "the dialog is NOT from the same context! Can't touch.."+((Activity)(cthw).getBaseContext()).getClass());
                        progressdialog = null;
                    }
                }


            }
        } 

 }

Using Visual Studio's Productivity Power Tools (free) extension helps a bit. Specifically, the Solution Error Visualizer feature. With it, compilation errors marked visually in the solution explorer (in the source file where the error was found). For some reason, however, this feature does not work as with other errors anywhere else in the code.

With MVC views, any compile-time errors will still be underlined in red in their respective .cs files, but signaling these errors is not propagated upwards in the Solution Explorer (in no way, even not in the containing source file).

Thanks for BlueClouds for correcting my previous statement.

I have just reported this as an issue on the extension's github project.

Try this:

INSERT INTO table1 SELECT "A string", 5, idTable2 FROM table2 WHERE ...

Use <br/> . For example:

A very old but simple enough technique is to use "Server-Side Includes", to include HTML pages into a top-level page that has the .shtml extension. For instance this would be your index.shtml file:

<html>
<head>...</head>
<body>
<!-- repeated header: note that the #include is in a HTML comment -->
<!--#include file="header.html" -->
<!-- unique content here... -->
</body>
</html>

Yes, it is lame, but it works. Remember to enable SSI support in your HTTP server configuration (this is how to do it for Apache).

I use many times the ImageMagic convert command to convert *.tif files to *.pdf files.

I don't know why but today I began to receive the following error:

convert: not authorized `a.pdf' @ error/constitute.c/WriteImage/1028.

After issuing the command:

convert a.tif a.pdf

After reading the above answers I edited the file /etc/ImageMagick-6/policy.xml

and changed the line:

policy domain="coder" rights="none" pattern="PDF" 

to

policy domain="coder" rights="read|write" pattern="PDF"

and now everything works fine.

I have "ImageMagick 6.8.9-9 Q16 x86_64 2018-09-28" on "Ubuntu 16.04.5 LTS".

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

EDIT: As pointed out in recent comments, this solution may BREAK your system.

You most likely don't want to remove python3.

Please refer to the other answers for possible solutions.

Outdated answer (not recommended)

sudo apt-get remove 'python3.*'

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

If you want to set this up once and use it everywhere, just configure your own middleware. When you are setting up your app, use the following to define a new function on the response object:

app.use((req, res, next) => {
  res.show = (name) => {
    res.sendFile(`/public/${name}`, {root: __dirname});
  };
  next();
});

Then use it as follows:

app.get('/demo', (req, res) => {
  res.show("index1.html");
});

if you use

angularjs

you have just to write the right css in order to frame you div html code

<div 
style="height:51px;width:111px;margin-left:203px;" 
ng-click="nextDetail()">
</div>

JS Code(in your controller):

$scope.nextDetail = function()
{
....
}

The %pdb magic command is good to use as well. Just say %pdb on and subsequently the pdb debugger will run on all exceptions, no matter how deep in the call stack. Very handy.

If you have a particular line that you want to debug, just raise an exception there (often you already are!) or use the %debug magic command that other folks have been suggesting.

This error occurs when you push the data from your local directory to your remote git repository by following git command: git push -u origin master

As local directory and git remote directory's files conflicted.

Solution :

After committing all files to staging follow below steps.

1. Fetch the files from the remote repository as its conflict with the local working directory.

   • git pull <remoter-url> <branch-name>

2. Commit the changes again.

   • git add -A
   • git commit -m ‘<comment>'

3. After committed merge files with both directory you can use

   • git push -u origin master

This will fix the issue. Thanks.

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or

For future reference, you can quickly create a truth table to check if it evaluates the way you want... it's kind of like Sudoku.

(!isset($action)) && ($action != "add" && $action != "delete"))

Example:

column 1 is issetaction, column 2 and 3 evaluates !="add","delete" respectively

if($a=nothing) T && (T && T) => T && T => TRUE

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

In Java, callback methods are mainly used to address the "Observer Pattern", which is closely related to "Asynchronous Programming".

Although callbacks are also used to simulate passing methods as a parameter, like what is done in functional programming languages.

Run cat -v file.sh.

You most likely have a carriage return or no-break space in your file. cat -v will show them as ^M and M-BM- or M- respectively. It will similarly show any other strange characters you might have gotten into your file.

Remove the Windows line breaks with

tr -d '\r' < file.sh > fixedfile.sh

I needed this today, and although the answers already given pointed me in the right direction, they weren't quite what I wanted.

Here's an implementation using Heap's method. The length of the array must be at least 3 and for practical considerations not be bigger than 10 or so, depending on what you want to do, patience and clock speed.

Before you enter your loop, initialise Perm(1 To N) with the first permutation, Stack(3 To N) with zeroes*, and Level with 2**. At the end of the loop call NextPerm, which will return false when we're done.

* VB will do that for you.

** You can change NextPerm a little to make this unnecessary, but it's clearer like this.

Option Explicit

Function NextPerm(Perm() As Long, Stack() As Long, Level As Long) As Boolean
Dim N As Long
If Level = 2 Then
    Swap Perm(1), Perm(2)
    Level = 3
Else
    While Stack(Level) = Level - 1
        Stack(Level) = 0
        If Level = UBound(Stack) Then Exit Function
        Level = Level + 1
    Wend
    Stack(Level) = Stack(Level) + 1
    If Level And 1 Then N = 1 Else N = Stack(Level)
    Swap Perm(N), Perm(Level)
    Level = 2
End If
NextPerm = True
End Function

Sub Swap(A As Long, B As Long)
A = A Xor B
B = A Xor B
A = A Xor B
End Sub

'This is just for testing.
Private Sub Form_Paint()
Const Max = 8
Dim A(1 To Max) As Long, I As Long
Dim S(3 To Max) As Long, J As Long
Dim Test As New Collection, T As String
For I = 1 To UBound(A)
    A(I) = I
Next
Cls
ScaleLeft = 0
J = 2
Do
    If CurrentY + TextHeight("0") > ScaleHeight Then
        ScaleLeft = ScaleLeft - TextWidth(" 0 ") * (UBound(A) + 1)
        CurrentY = 0
        CurrentX = 0
    End If
    T = vbNullString
    For I = 1 To UBound(A)
        Print A(I);
        T = T & Hex(A(I))
    Next
    Print
    Test.Add Null, T
Loop While NextPerm(A, S, J)
J = 1
For I = 2 To UBound(A)
    J = J * I
Next
If J <> Test.Count Then Stop
End Sub

Other methods are described by various authors. Knuth describes two, one gives lexical order, but is complex and slow, the other is known as the method of plain changes. Jie Gao and Dianjun Wang also wrote an interesting paper.

The new tests you wrote (directly or indirectly) use classes that log using Log4j.

Log4J needs to be configured for this logging to work properly.

Put a log4j.properties (or log4j.xml) file in the root of your test classpath.

It should have some basic configuration such as

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# An alternative logging format:
# log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n

An appender outputs to the console by default, but you can also explicitly set the target like this:

log4j.appender.A1.Target=System.out

This will redirect all output in a nice format to the console. More info can be found here in the Log4J manual,

Log4J Logging will then be properly configured and this warning will disappear.

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

import java.util.Scanner;
import java.util.Timer;
import java.util.TimerTask;

public class Stopwatch {
static int interval;
static Timer timer;

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    System.out.print("Input seconds => : ");
    String secs = sc.nextLine();
    int delay = 1000;
    int period = 1000;
    timer = new Timer();
    interval = Integer.parseInt(secs);
    System.out.println(secs);
    timer.scheduleAtFixedRate(new TimerTask() {

        public void run() {
            System.out.println(setInterval());

        }
    }, delay, period);
}

private static final int setInterval() {
    if (interval == 1)
        timer.cancel();
    return --interval;
}
}

Try this.

I have run into problems in the past with IE and the css:hover selector so the approach that I have taken, is to use a custom directive.

.directive('hoverClass', function () {
    return {
        restrict: 'A',
        scope: {
            hoverClass: '@'
        },
        link: function (scope, element) {
            element.on('mouseenter', function() {
                element.addClass(scope.hoverClass);
            });
            element.on('mouseleave', function() {
                element.removeClass(scope.hoverClass);
            });
        }
    };
})

then on the element itself you can add the directive with the class names that you want enabled when the mouse is over the the element for example:

<li data-ng-repeat="item in social" hover-class="hover tint" class="social-{{item.name}}" ng-mouseover="hoverItem(true);" ng-mouseout="hoverItem(false);"
                index="{{$index}}"><i class="{{item.icon}}"
                box="course-{{$index}}"></i></li>

This should add the class hover and tint when the mouse is over the element and doesn't run the risk of a scope variable name collision. I haven't tested but the mouseenter and mouseleave events should still bubble up to the containing element so in the given scenario the following should still work

<div hover-class="hover" data-courseoverview data-ng-repeat="course in courses | orderBy:sortOrder | filter:search"
 data-ng-controller ="CourseItemController"
 data-ng-class="{ selected: isSelected }">

providing of course that the li's are infact children of the parent div

in a simple way

import re

html_text = open('html_file.html').read()
text_filtered = re.sub(r'<(.*?)>', '', html_text)

this code finds all parts of the html_text started with '<' and ending with '>' and replace all found by an empty string

Scheme doesn't have algebraic data types or pattern matching but it's certainly a functional language. Annoying things about Python from a functional programming perspective:

1. Crippled Lambdas. Since Lambdas can only contain an expression, and you can't do everything as easily in an expression context, this means that the functions you can define "on the fly" are limited.

2. Ifs are statements, not expressions. This means, among other things, you can't have a lambda with an If inside it. (This is fixed by ternaries in Python 2.5, but it looks ugly.)

3. Guido threatens to remove map, filter, and reduce every once in a while

On the other hand, python has lexical closures, Lambdas, and list comprehensions (which are really a "functional" concept whether or not Guido admits it). I do plenty of "functional-style" programming in Python, but I'd hardly say it's ideal.

alias testcases="sed -n 's/func.*\(Test.*\)(.*/\1/p' | xargs | sed 's/ /|/g'"

go test -v -run $(cat coordinator_test.go | testcases)

try this single command to both delete and insert the data:

DELETE MyTable
    OUTPUT DELETED.Col1, DELETED.COl2,...
        INTO MyBackupTable

working sample:

--set up the tables
DECLARE @MyTable table (col1 int, col2 varchar(5))
DECLARE @MyBackupTable table (col1 int, col2 varchar(5))
INSERT INTO @MyTable VALUES (1,'A')
INSERT INTO @MyTable VALUES (2,'B')
INSERT INTO @MyTable VALUES (3,'C')
INSERT INTO @MyTable VALUES (4,'D')

--single command that does the delete and inserts
DELETE @MyTable
    OUTPUT DELETED.Col1, DELETED.COl2
        INTO @MyBackupTable

--show both tables final values
select * from @MyTable
select * from @MyBackupTable

OUTPUT:

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(4 row(s) affected)
col1        col2
----------- -----

(0 row(s) affected)

col1        col2
----------- -----
1           A
2           B
3           C
4           D

(4 row(s) affected)

I agree that Pascal's solution is the way to go, but for those saying that it adds an extra task to remove the comments, you can use the following comment style trick to simplify your life:

<?php /* ?>
<tr>
      <td><?php echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php echo $sort_order; ?>" size="1" /></td>
    </tr>
<?php // */ ?>

In order to stop the code block being commented out, simply change the opening comment to:

<?php //* ?>

Try this way:

<td><a href="..." style="display:block;">&nbsp;</a></td>

This might be helpful:

columns.Bound(date=> date.START_DATE).Title("Start Date").Format("{0:MM dd, yyyy}");

You can reset the mfrow parameter

par(mfrow=c(1,1))

Use a wrapper selector and create a container that has a 100% width inside of that wrapper to encapsulate the entire page.

<style>#wrapper {width: 1000px;} 
#wrapper .container {max-width: 100%; display: block;}</style>
<body>
<div id="wrapper">
  <div class="container">
    <div class="row">....

Now the maximum width is set to 1000px and you need no less or sass.

No. We cannot alter the constraint, only thing we can do is drop and recreate it

ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]

Foreign Key Constraint

Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade

Primary Key constraint

Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)

Use the backslash before db on the header and you can use it then typically as you wrote it before.

Here is the example:

Use \DB;

Then inside your controller class you can use as you did before, like that ie :

$item = DB::table('items')->get();

This worked for me-- (File -> Indicate Cashes) --> (Invalidate and Restart).

jQuery Ajax Notes

• Due to browser security restrictions, most Ajax requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, port, or protocol.
• Script and JSONP requests are not subject to the same origin policy restrictions.

There are some ways to overcome the cross-domain barrier:

• CORS Proxy Alternatives
• Ways to circumvent the same-origin policy
• Breaking The Cross Domain Barrier

There are some plugins that help with cross-domain requests:

• Cross Domain AJAX Request with YQL and jQuery
• Cross-domain requests with jQuery.ajax

Heads up!

The best way to overcome this problem, is by creating your own proxy in the back-end, so that your proxy will point to the services in other domains, because in the back-end not exists the same origin policy restriction. But if you can't do that in back-end, then pay attention to the following tips.

Using third-party proxies is not a secure practice, because they can keep track of your data, so it can be used with public information, but never with private data.

CORS Anywhere

CORS Anywhere is a node.js proxy which adds CORS headers to the proxied request.
To use the API, just prefix the URL with the API URL. (Supports https: see github repository)

If you want to automatically enable cross-domain requests when needed, use the following snippet:

$.ajaxPrefilter( function (options) {
  if (options.crossDomain && jQuery.support.cors) {
    var http = (window.location.protocol === 'http:' ? 'http:' : 'https:');
    options.url = http + '//cors-anywhere.herokuapp.com/' + options.url;
    //options.url = "http://cors.corsproxy.io/url=" + options.url;
  }
});

$.get(
    'http://en.wikipedia.org/wiki/Cross-origin_resource_sharing',
    function (response) {
        console.log("> ", response);
        $("#viewer").html(response);
});

Whatever Origin

Whatever Origin is a cross domain jsonp access. This is an open source alternative to anyorigin.com.

To fetch the data from google.com, you can use this snippet:

// It is good specify the charset you expect.
// You can use the charset you want instead of utf-8.
// See details for scriptCharset and contentType options: 
// http://api.jquery.com/jQuery.ajax/#jQuery-ajax-settings
$.ajaxSetup({
    scriptCharset: "utf-8", //or "ISO-8859-1"
    contentType: "application/json; charset=utf-8"
});

$.getJSON('http://whateverorigin.org/get?url=' + 
    encodeURIComponent('http://google.com') + '&callback=?',
    function (data) {
        console.log("> ", data);

        //If the expected response is text/plain
        $("#viewer").html(data.contents);

        //If the expected response is JSON
        //var response = $.parseJSON(data.contents);
});

CORS Proxy

CORS Proxy is a simple node.js proxy to enable CORS request for any website. It allows javascript code on your site to access resources on other domains that would normally be blocked due to the same-origin policy.

• CORS-Proxy gr2m
• CORS-Proxy rmadhuram

How does it work? CORS Proxy takes advantage of Cross-Origin Resource Sharing, which is a feature that was added along with HTML 5. Servers can specify that they want browsers to allow other websites to request resources they host. CORS Proxy is simply an HTTP Proxy that adds a header to responses saying "anyone can request this".

This is another way to achieve the goal (see www.corsproxy.com). All you have to do is strip http:// and www. from the URL being proxied, and prepend the URL with www.corsproxy.com/

$.get(
    'http://www.corsproxy.com/' +
    'en.wikipedia.org/wiki/Cross-origin_resource_sharing',
    function (response) {
        console.log("> ", response);
        $("#viewer").html(response);
});

CORS proxy browser

Recently I found this one, it involves various security oriented Cross Origin Remote Sharing utilities. But it is a black-box with Flash as backend.

You can see it in action here: CORS proxy browser
Get the source code on GitHub: koto/cors-proxy-browser

Yes use this

$("#phone").inputmask({"mask": "(99) 9999 - 9999"});

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

void trim(char* string) {
    int lenght = strlen(string);
    int i=0;

    while(string[0] ==' ') {
        for(i=0; i<lenght; i++) {
            string[i] = string[i+1];
        }
        lenght--;
    }


    for(i=lenght-1; i>0; i--) {
        if(string[i] == ' ') {
            string[i] = '\0';
        } else {
            break;
        }
    }
}

This should work for every default repo:

git pull origin master

If your default branch is different than master, you will need to specify the branch name:

git pull origin my_default_branch_name

Try running

lsof | grep /mnt/data

That should list any process that is accessing /mnt/data that would prevent it from being unmounted.

Mark,

I believe you want to use android:scaleType="fitXY".

You're thinking too complicated. It's actually just $('#'+openaddress).

Try curl -v http://localhost:8080/ instead of 127.0.0.1

Another way to do it, is creating a custom component extending TextView. It's good for cases where you need to have multiple underlined TextViews.

Here's the code for the component:

package com.myapp.components;

import android.content.Context;
import android.support.v7.widget.AppCompatTextView;
import android.text.SpannableString;
import android.text.style.UnderlineSpan;
import android.util.AttributeSet;

public class LinkTextView extends AppCompatTextView {
    public LinkTextView(Context context) {
        this(context, null);
    }

    public LinkTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        SpannableString content = new SpannableString(text);
        content.setSpan(new UnderlineSpan(), 0, content.length(), 0);

        super.setText(content, type);
    }
}

And how to use it in xml:

<com.myapp.components.LinkTextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hello World!" />

The Complete thing

DECLARE @v varchar(10)

SET @v='#temp'

select STUFF(@v, 1, 1, '')
WHERE LEFT(@v,1)='#'

const units = ['bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];

function niceBytes(x){

  let l = 0, n = parseInt(x, 10) || 0;

  while(n >= 1024 && ++l){
      n = n/1024;
  }
  //include a decimal point and a tenths-place digit if presenting 
  //less than ten of KB or greater units
  return(n.toFixed(n < 10 && l > 0 ? 1 : 0) + ' ' + units[l]);
}

Results:

niceBytes(435)                 // 435 bytes
niceBytes(3398)                // 3.3 KB
niceBytes(490398)              // 479 KB
niceBytes(6544528)             // 6.2 MB
niceBytes(23483023)            // 22 MB
niceBytes(3984578493)          // 3.7 GB
niceBytes(30498505889)         // 28 GB
niceBytes(9485039485039445)    // 8.4 PB

Seems like the only way to get decimal in a pretty (for me) form requires some ridiculous code.

The only solution I got so far:

CASE WHEN xy>0 and xy<1 then '0' || to_char(xy) else to_char(xy)

xy is a decimal.

xy             query result
0.8            0.8  --not sth like .80
10             10  --not sth like 10.00

import math as m
a=int(input("Enter the no"))
print(m.sqrt(a))

from math import sqrt
print(sqrt(25))

from math import sqrt as s
print(s(25))

from math import *
print(sqrt(25))

All works.

The stored procedures can be run in sql developer tool using the below syntax

BEGIN procedurename(); END;

If there are any parameters then it has to be passed.

I once also faced such an issue where i needed to save data which was used by different collaborators and i ended up storing the time in unix timestamp form which represents the number of seconds since january 1970 which is an integer format. Example todays date and time in tanzania is Friday, September 13, 2019 9:44:01 PM which when store in unix timestamp would be 1568400241

Now when reading the data simply use something like php or any other language and extract the date from the unix timestamp. An example with php will be

echo date('m/d/Y', 1568400241);

This makes it easier even to store data with other collaborators in different locations. They can simply convert the date to unix timestamp with their own gmt offset and store it in a integer format and when outputting this simply convert with a

In some systems one have to specify:

import os
os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"]=""  # or even "-1"

BEFORE importing tensorflow.

an idea:

<form method="POST" action="javascript:void(0);" onSubmit="CheckPassword()">
    <input id="pwset" type="text" size="20" name='pwuser'><br><br>
    <button type="button" onclick="CheckPassword()">Next</button>
</form>

and

<script type="text/javascript">
    $("#pwset").focus();
    function CheckPassword()
    {
        inputtxt = $("#pwset").val();
        //and now your code
        $("#div1").load("next.php #div2");
        return false;
    }
</script>

try something like :

var focusout = false;

$("#Button1").click(function () {
    if (focusout == true) {
        focusout = false;
        return;
    }
    else {
        GetInfo();
    }
});

$("#Text1").focusout(function () {
    focusout = true;
    GetInfo();
});

Though it is answered above and it is right to use

<meta name="viewport" content="width=device-width, initial-scale=1">

but if you are using React and webpack then don't forget to close the element tag

<meta name="viewport" content="width=device-width, initial-scale=1" />

How to pass dynamic constructor parameters too

If you want to pass dynamic constructor parameters to the class, you can use this code:

$reflectionClass = new ReflectionClass($className);

$module = $reflectionClass->newInstanceArgs($arrayOfConstructorParameters);

More information on dynamic classes and parameters

PHP >= 5.6

As of PHP 5.6 you can simplify this even more by using Argument Unpacking:

// The "..." is part of the language and indicates an argument array to unpack.
$module = new $className(...$arrayOfConstructorParameters);

Thanks to DisgruntledGoat for pointing that out.

For Python 2 try:

print unicode(string, 'unicode-escape')

For Python 3 try:

import os
string = "002 Could've Would've Should've"
os.system('echo ' + string)

Or try win-unicode-console:

pip install win-unicode-console
py -mrun your_script.py

You can achieve this by using the blur event on window element.

Here is a jQuery plugin for tracking click on iframes (it will fire a custom callback function when an iframe is clicked) : https://github.com/finalclap/iframeTracker-jquery

Use it like this :

jQuery(document).ready(function($){
    $('.iframe_wrap iframe').iframeTracker({
        blurCallback: function(){
            // Do something when iframe is clicked (like firing an XHR request)
        }
    });
});

From Asp.net core 2.2 to above you can code as below:

Step 1. Create an AppSettings class file.

This file contains some methods to help get value by key from the appsettings.json file. Look like as code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ReadConfig.Bsl
{
  public class AppSettings
  {
      private static AppSettings _instance;
      private static readonly object ObjLocked = new object();
      private IConfiguration _configuration;

      protected AppSettings()
      {
      }

      public void SetConfiguration(IConfiguration configuration)
      {
          _configuration = configuration;
      }

      public static AppSettings Instance
      {
          get
          {
              if (null == _instance)
              {
                  lock (ObjLocked)
                  {
                      if (null == _instance)
                          _instance = new AppSettings();
                  }
              }
              return _instance;
          }
      }

      public string GetConnection(string key, string defaultValue = "")
      {
          try
          {
              return _configuration.GetConnectionString(key);
          }
          catch
          {
              return defaultValue;
          }
      }

      public T Get<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public T Get<T>(string key, T defaultValue)
      {
          if (_configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public static T GetObject<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
          {
              var section = Instance._configuration.GetSection(key);
              return section.Get<T>();
          }
      }

      public static T GetObject<T>(string key, T defaultValue)
      {
          if (Instance._configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
              return Instance._configuration.GetSection(key).Get<T>();
      }
  }
}

Step 2. Initial configuration for AppSettings object

We need to declare and load appsettings.json file when the application starts, and load configuration information for AppSettings object. We will do this work in the constructor of the Startup.cs file. Please notice line AppSettings.Instance.SetConfiguration(Configuration);

public Startup(IHostingEnvironment evm)
{
    var builder = new ConfigurationBuilder()
      .SetBasePath(evm.ContentRootPath)
      .AddJsonFile("appsettings.json", true, true)
      .AddJsonFile($"appsettings.{evm.EnvironmentName}.json", true)
      .AddEnvironmentVariables();
    Configuration = builder.Build(); // load all file config to Configuration property 
    AppSettings.Instance.SetConfiguration(Configuration);       
}

Okay, now I have an appsettings.json file with some keys as below:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "ConnectionString": "Data Source=localhost;Initial Catalog=ReadConfig;Persist Security Info=True;User ID=sa;Password=12345;"
  },
  "MailConfig": {
    "Servers": {
      "MailGun": {
        "Pass": "65-1B-C9-B9-27-00",
        "Port": "587",
        "Host": "smtp.gmail.com"
      }
    },
    "Sender": {
      "Email": "[email protected]",
      "Pass": "123456"
    }
  }
}

Step 3. Read config value from an action

I make demo an action in Home controller as below :

public class HomeController : Controller
{
    public IActionResult Index()
    {
        var connectionString = AppSettings.Instance.GetConnection("ConnectionString");
        var emailSender = AppSettings.Instance.Get<string>("MailConfig:Sender:Email");
        var emailHost = AppSettings.Instance.Get<string>("MailConfig:Servers:MailGun:Host");

        string returnText = " 1. Connection String \n";
        returnText += "  " +connectionString;
        returnText += "\n 2. Email info";
        returnText += "\n Sender : " + emailSender;
        returnText += "\n Host : " + emailHost;

        return Content(returnText);
    }
}

And below is the result:

For more information, you can refer article get value from appsettings.json in asp.net core for more detail code.

While not a Nodejs setting, I suggest you use proxychains which I find rather convenient. It is probably available in your package manager.

After setting the proxy in the config file (/etc/proxychains.conf for me), you can run proxychains npm start or proxychains4 npm start (i.e. proxychains [command_to_proxy_transparently]) and all your requests will be proxied automatically.

Config settings for me:

These are the minimal settings you will have to append

## Exclude all localhost connections (dbs and stuff)
localnet 0.0.0.0/0.0.0.0
## Set the proxy type, ip and port here
http    10.4.20.103 8080

(You can get the ip of the proxy by using nslookup [proxyurl])

In addition, if you run a HTML document with multiple <tbody> tags through W3C's HTML Validator, with a HTML5 DOCTYPE, it will successfully validate.

I often use a github starter project, like this (it uses babel)

Maybe I didn't understand the question correctly, but can you not use keyup if you want to capture both inputs?

$("input").bind("keyup",function(e){
    var value = this.value + String.fromCharCode(e.keyCode);
});

//Update 2018, works//

Method1:

Download phpseclib v1 and use this code:

<?php
set_include_path(__DIR__ . '/phpseclib1.0.11');
include("Net/SSH2.php");

$key ="MyPassword";
  /* ### if using PrivateKey ### 
  include("Crypt/RSA.php");
  $key = new Crypt_RSA();
  $key->loadKey(file_get_contents('private-key.ppk'));
  */

$ssh = new Net_SSH2('www.example.com', 22);   // Domain or IP
if (!$ssh->login('your_username', $key))  exit('Login Failed');

echo $ssh->exec('pwd');
?>

or Method2:

Download newest phpseclib v2 (requires composer install at first):

<?php

set_include_path($path=__DIR__ . '/phpseclib-master/phpseclib');
include ($path.'/../vendor/autoload.php');

$loader = new \Composer\Autoload\ClassLoader();

use phpseclib\Net\SSH2;

$key ="MyPassword";
  /* ### if using PrivateKey ### 
  use phpseclib\Crypt\RSA;
  $key = new RSA();
  $key->load(file_get_contents('private-key.ppk'));
  */

$ssh = new SSH2('www.example.com', 22);   // Domain or IP
if (!$ssh->login('your_username', $key))   exit('Login Failed'); 

echo $ssh->exec('pwd');
?>

p.s. if you get "Connection timed out" then it's probably the issue of HOST/FIREWALL (local or remote) or like that, not a fault of script.

If you are using MVC then it would be more appropriate to use RedirectResult instead of using Response.Redirect.

public ActionResult Index() {
        return new RedirectResult("http://www.website.com");
    }

Reference - https://blogs.msdn.microsoft.com/rickandy/2012/03/01/response-redirect-and-asp-net-mvc-do-not-mix/

The problem is, that adding two Int16 results in an Int32 as others have already pointed out.
Your second question, why this problem doesn't already occur at the declaration of those two variables is explained here: http://msdn.microsoft.com/en-us/library/ybs77ex4%28v=VS.71%29.aspx:

short x = 32767;

In the preceding declaration, the integer literal 32767 is implicitly converted from int to short. If the integer literal does not fit into a short storage location, a compilation error will occur.

So, the reason why it works in your declaration is simply that the literals provided are known to fit into a short.

Since I needed to analyze fat jars I was interested in the version of each individual class in a jar file.

Using NSCoding and NSKeyedArchiver is another great option for data that's too complex for NSUserDefaults, but for which CoreData would be overkill. It also gives you the opportunity to manage the file structure more explicitly, which is great if you want to use encryption.

<button id="1" onClick="reply_click()"></button>
<button id="2" onClick="reply_click()"></button>
<button id="3" onClick="reply_click()"></button>

function reply_click()
{
   console.log(window.event.target.id)
}

The following has worked for me.

I had a lot of local changes and needed to discard those in the local copy and checkout the last stable version in SVN.

1. Check the status of all files, including the ignored files.

2. Grep all the lines to get the newly added and ignored files.

3. Replace those with //.

4. and rm -rf all the lines.

   svn status --no-ignore | grep '^[?I]' | sed "s/^[?I] //" | xargs -I{} rm -rf "{}"

Use CAST with following parameters:

Date

select Cast('2017-10-11 14:38:50.440' as date)

Output: 2017-10-11

Datetime

select Cast('2017-10-11 14:38:50.440' as datetime)

Output: 2017-10-11 14:38:50.440

SmallDatetime

select Cast('2017-10-11 14:38:50.440' as smalldatetime)

Output: 2017-10-11 14:39:00

DatetimeOffset

select Cast('2017-10-11 14:38:50.440' as datetimeoffset)

Output: 2017-10-11 14:38:50.4400000 +00:00

Datetime2

select Cast('2017-10-11 14:38:50.440' as datetime2)

Output: 2017-10-11 14:38:50.4400000

What are the differences between the assignment operators = and <- in R?

As your example shows, = and <- have slightly different operator precedence (which determines the order of evaluation when they are mixed in the same expression). In fact, ?Syntax in R gives the following operator precedence table, from highest to lowest:

…
‘-> ->>’           rightwards assignment
‘<- <<-’           assignment (right to left)
‘=’                assignment (right to left)
…

But is this the only difference?

Since you were asking about the assignment operators: yes, that is the only difference. However, you would be forgiven for believing otherwise. Even the R documentation of ?assignOps claims that there are more differences:

The operator <- can be used anywhere, whereas the operator = is only allowed at the top level (e.g., in the complete expression typed at the command prompt) or as one of the subexpressions in a braced list of expressions.

Let’s not put too fine a point on it: the R documentation is wrong. This is easy to show: we just need to find a counter-example of the = operator that isn’t (a) at the top level, nor (b) a subexpression in a braced list of expressions (i.e. {…; …}). — Without further ado:

x
# Error: object 'x' not found
sum((x = 1), 2)
# [1] 3
x
# [1] 1

Clearly we’ve performed an assignment, using =, outside of contexts (a) and (b). So, why has the documentation of a core R language feature been wrong for decades?

It’s because in R’s syntax the symbol = has two distinct meanings that get routinely conflated (even by experts, including in the documentation cited above):

1. The first meaning is as an assignment operator. This is all we’ve talked about so far.
2. The second meaning isn’t an operator but rather a syntax token that signals named argument passing in a function call. Unlike the = operator it performs no action at runtime, it merely changes the way an expression is parsed.

So how does R decide whether a given usage of = refers to the operator or to named argument passing? Let’s see.

In any piece of code of the general form …

‹function_name›(‹argname› = ‹value›, …)
‹function_name›(‹args›, ‹argname› = ‹value›, …)

… the = is the token that defines named argument passing: it is not the assignment operator. Furthermore, = is entirely forbidden in some syntactic contexts:

if (‹var› = ‹value›) …
while (‹var› = ‹value›) …
for (‹var› = ‹value› in ‹value2›) …
for (‹var1› in ‹var2› = ‹value›) …

Any of these will raise an error “unexpected '=' in ‹bla›”.

In any other context, = refers to the assignment operator call. In particular, merely putting parentheses around the subexpression makes any of the above (a) valid, and (b) an assignment. For instance, the following performs assignment:

median((x = 1 : 10))

But also:

if (! (nf = length(from))) return()

_{Now you might object that such code is atrocious (and you may be right). But I took this code from the base::file.copy function (replacing <- with =) — it’s a pervasive pattern in much of the core R codebase.}

The original explanation by John Chambers, which the the R documentation is probably based on, actually explains this correctly:

[= assignment is] allowed in only two places in the grammar: at the top level (as a complete program or user-typed expression); and when isolated from surrounding logical structure, by braces or an extra pair of parentheses.

In sum, by default the operators <- and = do the same thing. But either of them can be overridden separately to change its behaviour. By contrast, <- and -> (left-to-right assignment), though syntactically distinct, always call the same function. Overriding one also overrides the other. Knowing this is rarely practical but it can be used for some fun shenanigans.

A few things I've noted:

• SurfaceViews contain a nice rendering mechanism that allows threads to update the surface's content without using a handler (good for animation).
• Surfaceviews cannot be transparent, they can only appear behind other elements in the view hierarchy.
• I've found that they are much faster for animation than rendering onto a View.

For more information (and a great usage example) refer to the LunarLander project in the SDK 's examples section.

You can do this with "cat" and a here-document.

cat <<EOF > test.txt
some text
EOF

One reason for doing this would be to avoid any possibility of a password being visible in the output of ps. However, in bash and most modern shells, "echo" is a built-in command and it won't show up in ps output, so using something like this is safe (ignoring any issues with storing passwords in files, of course):

echo "$password" > test.txt

RaeLehman's solution works if you only want to generate the dialog's content once (or only modify it using javascript). If you actually want to regenerate the dialog each time (e.g., using a view model class and Razor), then you can close all dialogs with $(".ui-dialog-titlebar-close").click(); and leave autoOpen set to its default value of true.

Take a look at this tutorial for how to use SQL inside VBA:

http://www.ehow.com/how_7148832_access-vba-query-results.html

For a query that won't return results, use (reference here):

DoCmd.RunSQL

For one that will, use (reference here):

Dim dBase As Database
dBase.OpenRecordset

For those who use mybatis, here is an example update statement:

<update id="saveAnswer">
    update quiz_execution set answer_data = jsonb_set(answer_data, concat('{', #{qid}, '}')::text[], #{value}::jsonb), updated_at = #{updatedAt}
    where id = #{id}
</update>

Params:

• qid, the key for field.
• value, is a valid json string, for field value,
  e.g converted from object to json string via jackson,

You can use the description method inherited by NSDictionary from NSObject, or write a custom method that formats NSDictionary to your liking.

I had the same problem in Flask.

When I added:

to tests folder, problem disappeared :)

Probably application couldn't recognize folder tests as module

how about doing it the way hooktube does it? they don't actually use the video URL for the html5 element, but the google video redirector url that calls upon that video. check out here's how they present some despacito random video...

<video id="player-obj" controls="" src="https://redirector.googlevideo.com/videoplayback?ratebypass=yes&amp;mt=1510077993----SKIPPED----amp;utmg=ytap1,,hd720"><source>Your browser does not support HTML5 video.</video>

the code is for the following video page https://hooktube.com/watch?v=72UO0v5ESUo

youtube to mp3 on the other hand has turned into extremely monetized monster that returns now download.html on half of video download requests... annoying...

the 2 links in this answer are to my personal experiences with both resources. how hooktube is nice and fresh and actually helps avoid censorship and geo restrictions.. check it out, it's pretty cool. and youtubeinmp4 is a popup monster now known as ConvertInMp4...

There is one way to do this, as long as you have regular time intervals between all your date-time values - make the x-axis consider the values as text.

in Excel 2007, click on the chart - Go to the layout menu (contextual menu on clicking on the chart) , choose the option Axes->Primary Horizontal Axes-> More Horizontal Axes Options
Under Axis Type, choose "Text Axis"

There is the wget command or the curl.

You can now use the file you downloaded with wget. Or you can handle a stream with curl.

Resources :

• linux.die - man wget
• linux.die - man curl

This is one of the dumb mistakes I've done. I spent a lot of time trying to debug this problem and tried all the responses posted above, but in the end, it was one of my many dumb mistakes.

I was using org.apache.logging.log4j.Logger (:fml:) whereas I should have used org.apache.log4j.Logger. Using this correct logger saved my evening.

This is basic code to find and play an audio file in Swift.

Add your audio file to your Xcode and add the code below.

import AVFoundation

class ViewController: UIViewController {

   var audioPlayer = AVAudioPlayer() // declare globally

   override func viewDidLoad() {
        super.viewDidLoad()

        guard let sound = Bundle.main.path(forResource: "audiofilename", ofType: "mp3") else {
            print("Error getting the mp3 file from the main bundle.")
            return
        }
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: sound))
        } catch {
            print("Audio file error.")
        }
        audioPlayer.play()
    }

    @IBAction func notePressed(_ sender: UIButton) { // Button action
        audioPlayer.stop()
    }
}

here: C:\Program Files\Java\jre7\bin it is an exe keytool.exe

I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:

 $stringRepresentation= json_encode($arr);

You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else. By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment in order to find the action.

You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.

To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)

egrep '(vmx|svm)' /proc/cpuinfo

To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.

In order to get the http status code returned from the server, you can add validateStatus: status => true to axios options:

axios({
    method: 'POST',
    url: 'http://localhost:3001/users/login',
    data: { username, password },
    validateStatus: () => true
}).then(res => {
    console.log(res.status);
});

This way, every http response resolves the promise returned from axios.

Using c-promise2 lib the cancellable fetch with timeout might look like this one (Live jsfiddle demo):

import CPromise from "c-promise2"; // npm package

function fetchWithTimeout(url, {timeout, ...fetchOptions}= {}) {
    return new CPromise((resolve, reject, {signal}) => {
        fetch(url, {...fetchOptions, signal}).then(resolve, reject)

There are two possible reasons for that error:

1. your jquery script file referencing is not valid

2. try to put your jquery code in document.ready, like this:

   $(document).ready(function(){

   ....your code....

   });

Sounds like this SO question may be relevant to you:

How can I convince IE to simply display Application json rather than offer to download

If not:

Have you tried setting the dataType expected in the ajax options? i.e. dataType: 'json'

Have you tried other content types such as 'application/json' or 'text/javascript'

1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:

Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:

@Cmyker, great solution for chart.js v2

One little enhancement: It makes sense to check for the appropriate canvas id, see the modified snippet below. Otherwise the text (i.e. 75%) is also rendered in middle of other chart types within the page.

  Chart.pluginService.register({
    beforeDraw: function(chart) {
      if (chart.canvas.id === 'doghnutChart') {
        let width = chart.chart.width,
            height = chart.chart.outerRadius * 2,
            ctx = chart.chart.ctx;

        rewardImg.width = 40;
        rewardImg.height = 40;
        let imageX = Math.round((width - rewardImg.width) / 2),
            imageY = (height - rewardImg.height ) / 2;

        ctx.drawImage(rewardImg, imageX, imageY, 40, 40);
        ctx.save();
      }
    }
  });

Since a legend (see: http://www.chartjs.org/docs/latest/configuration/legend.html) magnifies the chart height, the value for height should be obtained by the radius.

Are you stuck using only those attributes? If not, it might be nice to create an array of child nodes, where you can cycle through all these objects once to build such attributes. From there, select the node with children but no parents and iteratively build your tree from the top down.

Ok, there are a bunch of ways you can do that. Yes, you can use plain old JS. Just try:

let dt1 = new Date()
let dt2 = new Date()

Let's emulate passage using Date.prototype.setMinutes and make sure we are in range.

dt1.setMinutes(7)
dt2.setMinutes(42)
console.log('Elapsed seconds:',(dt2-dt1)/1000)

Alternatively you could use some library like js-joda, where you can easily do things like this (directly from docs):

var dt1 = LocalDateTime.parse("2016-02-26T23:55:42.123");
var dt2 = dt1
  .plusYears(6)
  .plusMonths(12)
  .plusHours(2)
  .plusMinutes(42)
  .plusSeconds(12);

// obtain the duration between the two dates
dt1.until(dt2, ChronoUnit.YEARS); // 7
dt1.until(dt2, ChronoUnit.MONTHS); // 84
dt1.until(dt2, ChronoUnit.WEEKS); // 356
dt1.until(dt2, ChronoUnit.DAYS); // 2557
dt1.until(dt2, ChronoUnit.HOURS); // 61370
dt1.until(dt2, ChronoUnit.MINUTES); // 3682242
dt1.until(dt2, ChronoUnit.SECONDS); // 220934532

There are plenty more libraries ofc, but js-joda has an added bonus of being available also in Java, where it has been extensively tested. All those tests have been migrated to js-joda, it's also immutable.

>>> list1 = [[], [], [], [], [], 'text', 'text2', [], 'moreText']
>>> list2 = [e for e in list1 if e]
>>> list2
['text', 'text2', 'moreText']

In your case you can use __FILE__ variable !
It should help.
It is one of predefined.

Since optparse has been mentioned a couple of times in the answers, and it provides a comprehensive kit for command line processing, here's a short simplified example of how you can use it, assuming the input file exists:

script.R:

library(optparse)

option_list <- list(
  make_option(c("-n", "--count_lines"), action="store_true", default=FALSE,
    help="Count the line numbers [default]"),
  make_option(c("-f", "--factor"), type="integer", default=3,
    help="Multiply output by this number [default %default]")
)

parser <- OptionParser(usage="%prog [options] file", option_list=option_list)

args <- parse_args(parser, positional_arguments = 1)
opt <- args$options
file <- args$args

if(opt$count_lines) {
  print(paste(length(readLines(file)) * opt$factor))
}

Given an arbitrary file blah.txt with 23 lines.

On the command line:

Rscript script.R -h outputs

Usage: script.R [options] file


Options:
        -n, --count_lines
                Count the line numbers [default]

        -f FACTOR, --factor=FACTOR
                Multiply output by this number [default 3]

        -h, --help
                Show this help message and exit

Rscript script.R -n blah.txt outputs [1] "69"

Rscript script.R -n -f 5 blah.txt outputs [1] "115"

states_list = states.split(' ')

In regards to your edit:

from random import choice
random_state = choice(states_list)

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

Everything has many properties and behaviours so take whatever object you want TV, Mobile, Car, Human or anything.

Abstraction:

1. Process of picking the essence of an object you really need
2. In other words, pick the properties you need from the object Example:
   a. TV - Sound, Visuals, Power Input, Channels Input.
   b. Mobile - Button/Touch screen, power button, volume button, sim port.
   c. Car - Steering, Break, Clutch, Accelerator, Key Hole.
   d. Human - Voice, Body, Eye Sight, Hearing, Emotions.

Encapsulation:

1. Process of hiding the details of an object you don't need
2. In other words, hide the properties and operations you don't need from the object but are required for the object to work properly Example:
   a. TV - Internal and connections of Speaker, Display, Power distribution b/w components, Channel mechanism.
   b. Mobile - How the input is parsed and processed, How pressing a button on/off or changes volumes, how sim will connect to service providers.
   c. Car - How turning steering turns the car, How break slow or stops the car, How clutch works, How accelerator increases speed, How key hole switch on/of the car.
   d. Human - How voice is produced, What's inside the body, How eye sight works, How hearing works, How emotions generate and effect us.

ABSTRACT everything you need and ENCAPSULATE everything you don't need ;)

None of the other answers worked in my case, most likely because the JSON array contained special characters. What fixed it for me:

Javascript (added encodeURIComponent)

var JSONstr = encodeURIComponent(JSON.stringify(fullInfoArray));
document.getElementById('JSONfullInfoArray').value = JSONstr;

PHP (unchanged from the question)

$data = json_decode($_POST["JSONfullInfoArray"]);
var_dump($data);

echo($_POST["JSONfullInfoArray"]);

Both echo and var_dump have been verified to work fine on a sample of more than 2000 user-entered datasets that included a URL field and a long text field, and that were returning NULL on var_dump for a subset that included URLs with the characters ?&#.

Just as we refer to scrolling class

Change

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS = new CERas.CERAS(); 
    } 

to

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS c = new CERas.CERAS(); 
    } 

Or if you wish to use it later again

change it to

using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace WinApp_WMI2 
{ 
    public partial class Form1 : Form 
    { 
        CERas.CERAS m_CERAS;

        public Form1() 
        { 
            InitializeComponent(); 
        } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
        m_CERAS = new CERas.CERAS(); 
    } 
} 


}

Add Cloneable and below code to your class

public Object clone() throws CloneNotSupportedException {
        return super.clone();
    }

Use this clonedObject = (YourClass) yourClassObject.clone();

If you want to do it using .map() or just want to know how it works you can do it like this:

var added=false;
$.map(arr, function(elementOfArray, indexInArray) {
 if (elementOfArray.id == productID) {
   elementOfArray.price = productPrice;
   added = true;
 }
}
if (!added) {
  arr.push({id: productID, price: productPrice})
}

The function handles each element separately. The .inArray() proposed in other answers is probably the more efficient way to do it.

This method is the simplest way for beginners to control Layouts rendering in your ASP.NET MVC application. We can identify the controller and render the Layouts as par controller, to do this we can write our code in _ViewStart file in the root directory of the Views folder. Following is an example shows how it can be done.

@{
    var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["Controller"].ToString();
    string cLayout = "";

    if (controller == "Webmaster")
        cLayout = "~/Views/Shared/_WebmasterLayout.cshtml";
    else
        cLayout = "~/Views/Shared/_Layout.cshtml";

    Layout = cLayout;
}

}); 
$(window).on("scrollstop",function(){
   $('nav').removeClass('shrink');
}); 

You will need to assign an ID to the checkbox:

Overview of Scanner.hasNextXXX methods

java.util.Scanner has many hasNextXXX methods that can be used to validate input. Here's a brief overview of all of them:

• hasNext() - does it have any token at all?
• hasNextLine() - does it have another line of input?
• For Java primitives
  • hasNextInt() - does it have a token that can be parsed into an int?
  • Also available are hasNextDouble(), hasNextFloat(), hasNextByte(), hasNextShort(), hasNextLong(), and hasNextBoolean()
  • As bonus, there's also hasNextBigInteger() and hasNextBigDecimal()
  • The integral types also has overloads to specify radix (for e.g. hexadecimal)
• Regular expression-based
  • hasNext(String pattern)
  • hasNext(Pattern pattern) is the Pattern.compile overload

Scanner is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern), which lets you define what pattern separates your tokens. There are also find and skip methods that ignores delimiters.

The following discussion will keep the regex as simple as possible, so the focus remains on Scanner.

Example 1: Validating positive ints

Here's a simple example of using hasNextInt() to validate positive int from the input.

Scanner sc = new Scanner(System.in);
int number;
do {
    System.out.println("Please enter a positive number!");
    while (!sc.hasNextInt()) {
        System.out.println("That's not a number!");
        sc.next(); // this is important!
    }
    number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);

Here's an example session:

Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5

Note how much easier Scanner.hasNextInt() is to use compared to the more verbose try/catch Integer.parseInt/NumberFormatException combo. By contract, a Scanner guarantees that if it hasNextInt(), then nextInt() will peacefully give you that int, and will not throw any NumberFormatException/InputMismatchException/NoSuchElementException.

Related questions

• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Example 2: Multiple hasNextXXX on the same token

Note that the snippet above contains a sc.next() statement to advance the Scanner until it hasNextInt(). It's important to realize that none of the hasNextXXX methods advance the Scanner past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!

This has two consequences:

• If you need to skip the "garbage" input that fails your hasNextXXX test, then you need to advance the Scanner one way or another (e.g. next(), nextLine(), skip, etc).
• If one hasNextXXX test fails, you can still test if it perhaps hasNextYYY!

Here's an example of performing multiple hasNextXXX tests.

Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
    System.out.println(
        sc.hasNextInt() ? "(int) " + sc.nextInt() :
        sc.hasNextLong() ? "(long) " + sc.nextLong() :  
        sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
        sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
        "(String) " + sc.next()
    );
}

Here's an example session:

5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit

Note that the order of the tests matters. If a Scanner hasNextInt(), then it also hasNextLong(), but it's not necessarily true the other way around. More often than not you'd want to do the more specific test before the more general test.

Example 3 : Validating vowels

Scanner has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.

Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
    System.out.println("That's not a vowel!");
    sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);

Here's an example session:

Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e

In regex, as a Java string literal, the pattern "[aeiou]" is what is called a "character class"; it matches any of the letters a, e, i, o, u. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner.

• java.util.regex.Pattern

Example 4: Using two Scanner at once

Sometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner, where the second Scanner takes the nextLine() from the first Scanner as input. Here's an example:

Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
    Scanner lineSc = new Scanner(sc.nextLine());
    int sum = 0;
    while (lineSc.hasNextInt()) {
        sum += lineSc.nextInt();
    }
    System.out.println("Sum is " + sum);
}

Here's an example session:

Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit

In addition to Scanner(String) constructor, there's also Scanner(java.io.File) among others.

Summary

• Scanner provides a rich set of features, such as hasNextXXX methods for validation.
• Proper usage of hasNextXXX/nextXXX in combination means that a Scanner will NEVER throw an InputMismatchException/NoSuchElementException.
• Always remember that hasNextXXX does not advance the Scanner past any input.
• Don't be shy to create multiple Scanner if necessary. Two simple Scanner is often better than one overly complex Scanner.
• Finally, even if you don't have any plans to use the advanced regex features, do keep in mind which methods are regex-based and which aren't. Any Scanner method that takes a String pattern argument is regex-based.
  • Tip: an easy way to turn any String into a literal pattern is to Pattern.quote it.

There are two reasons you might get this message:

1. ASP.Net is not configured. For this run from Administrator command %FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.
2. Another reason this may happen is because your App Pool is not configured correctly. For example, you created website for WordPress and you also want to throw in few aspx files in there, WordPress creates app pool that says don't run CLR stuff. To fix this just open up App Pool and enable CLR.

You have misspelt the second pixels as pixel. The following works:

pixels = [1,2,3]
pixels[0] = 5

It appears that due to the typo you were trying to accidentally modify some tuple called pixel, and in Python tuples are immutable. Hence the confusing error message.

Try this it worked for me

Write this in your Controller

public class DemoController: Controller

        public async Task<FileStreamResult> GetLogoImage(string logoimage)
        {
            string str = "" ;
            var filePath = Server.MapPath("~/App_Data/" + SubfolderName);//If subfolder exist otherwise leave.
            // DirectoryInfo dir = new DirectoryInfo(filePath);
            string[] filePaths = Directory.GetFiles(@filePath, "*.*");
            foreach (var fileTemp in filePaths)
            {
                  str= fileTemp.ToString();
            }
                return File(new MemoryStream(System.IO.File.ReadAllBytes(str)), System.Web.MimeMapping.GetMimeMapping(str), Path.GetFileName(str));
        }

Here is my view

<div><a href="/DemoController/GetLogoImage?Type=Logo" target="_blank">Download Logo</a></div>

System.out.println(myList.size());

Since no elements are in the list

output => 0

myList.add("newString");  // use myList.add() to insert elements to the arraylist
System.out.println(myList.size());

Since one element is added to the list

output => 1

I was able to solve this one by following the steps listed here:http://forum.xda-developers.com/showthread.php?t=2247471

It would be much better to realize that talking of physical lines of code is pretty meaningless. The number of physical Lines of Code (LoC) is so dependent on the coding style that it can vary of an order of magnitude from one developer to another one.

In the .NET world there are a convenient way to count the LoC. Sequence point. A sequence point is a unit of debugging, it is the code portion highlighted in dark-red when putting a break point. With sequence point we can talk of logical LoC, and this metric can be compared across various .NET languages. The logical LoC code metric is supported by most .NET tools including VisualStudio code metric, NDepend or NCover.

For example, here is a 8 LoC method (beginning and ending brackets sequence points are not taken account):

The production of LoC must be counted in the long term. Some days you'll spit more than 200 LoC, some others days you'll spend 8 hours fixing a bug by not even adding a single LoC. Some days you'll clean dead code and will remove LoC, some days you'll spend all your time refactoring existing code and not adding any new LoC to the total.

Personally, I count a single LoC in my own productivity score only when:

1. It is covered by unit-tests
2. it is associated to some sort of code contract (if possible, not all LoC of course can be checked by contracts).

In this condition, my personal score over the last 5 years coding the NDepend tool for .NET developers is an average of 80 physical LoC per day without sacrificing by any mean the code quality. The rhythm is sustained and I don't see it decreased any time soon. All in all, NDepend is a C# code base that currently weights around 115K physical LoC

For those who hates counting LoC (I saw many of them in comments here), I attest that once adequately calibrated, counting LoC is an excellent estimation tool. After coding and measuring dozens of features achieved in my particular context of development, I reached the point where I can estimate precisely the size of any TODO feature in LoC, and the time it'll take me to deliver it to production.

I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).

I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.

$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
    //windows
    pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
    //linux
    shell_exec( $command . " > /dev/null 2>&1 &" );
}

This worked perfectly for me.

I hope it will help someone with windows. Cheers.

If you are already doing databinding:

<asp:Calendar ID="Calendar1" runat="server"  SelectedDate="<%# DateTime.Today %>" />

Will do it. This does require that somewhere you are doing a Page.DataBind() call (or a databind call on a parent control). If you are not doing that and you absolutely do not want any codebehind on the page, then you'll have to create a usercontrol that contains a calendar control and sets its selecteddate.
