The encoding declaration identifies which encoding is used to represent the characters in the document.

More on the XML Declaration here: http://msdn.microsoft.com/en-us/library/ms256048.aspx

In XML 1.0, the XML Declaration is optional. See section 2.8 of the XML 1.0 Recommendation, where it says it "should" be used -- which means it is recommended, but not mandatory. In XML 1.1, however, the declaration is mandatory. See section 2.8 of the XML 1.1 Recommendation, where it says "MUST" be used. It even goes on to state that if the declaration is absent, that automatically implies the document is an XML 1.0 document.

Note that in an XML Declaration the encoding and standalone are both optional. Only the version is mandatory. Also, these are not attributes, so if they are present they must be in that order: version, followed by any encoding, followed by any standalone.

<?xml version="1.0"?>
<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" standalone="yes"?>
<?xml version="1.0" encoding="UTF-16" standalone="yes"?>

If you don't specify the encoding in this way, XML parsers try to guess what encoding is being used. The XML 1.0 Recommendation describes one possible way character encoding can be autodetected. In practice, this is not much of a problem if the input is encoded as UTF-8, UTF-16 or US-ASCII. Autodetection doesn't work when it encounters 8-bit encodings that use characters outside the US-ASCII range (e.g. ISO 8859-1) -- avoid creating these if you can.

The standalone indicates whether the XML document can be correctly processed without the DTD or not. People rarely use it. These days, it is a bad to design an XML format that is missing information without its DTD.

Update:

A "prolog error/invalid utf-8 encoding" error indicates that the actual data the parser found inside the file did not match the encoding that the XML declaration says it is. Or in some cases the data inside the file did not match the autodetected encoding.

Since your file contains a byte-order-mark (BOM) it should be in UTF-16 encoding. I suspect that your declaration says <?xml version="1.0" encoding="UTF-8"?> which is obviously incorrect when the file has been changed into UTF-16 by NotePad. The simple solution is to remove the encoding and simply say <?xml version="1.0"?>. You could also edit it to say encoding="UTF-16" but that would be wrong for the original file (which wasn't in UTF-16) or if the file somehow gets changed back to UTF-8 or some other encoding.

Don't bother trying to remove the BOM -- that's not the cause of the problem. Using NotePad or WordPad to edit XML is the real problem!

Do while loop will be executed atleast once.......but while loop will check the condition first and then it may or may not get executed depending on the condition.

In your example wdlen may assume any garbage value which is > 2 so while loop will never get executed.

whereas do while loop will be ececuted and will tell u to enter the value and check that value in terminating condition

In C, a "stream" is an abstraction; from the program's perspective it is simply a producer (input stream) or consumer (output stream) of bytes. It can correspond to a file on disk, to a pipe, to your terminal, or to some other device such as a printer or tty. The FILE type contains information about the stream. Normally, you don't mess with a FILE object's contents directly, you just pass a pointer to it to the various I/O routines.

There are three standard streams: stdin is a pointer to the standard input stream, stdout is a pointer to the standard output stream, and stderr is a pointer to the standard error output stream. In an interactive session, the three usually refer to your console, although you can redirect them to point to other files or devices:

$ myprog < inputfile.dat > output.txt 2> errors.txt

In this example, stdin now points to inputfile.dat, stdout points to output.txt, and stderr points to errors.txt.

fprintf writes formatted text to the output stream you specify.

printf is equivalent to writing fprintf(stdout, ...) and writes formatted text to wherever the standard output stream is currently pointing.

sprintf writes formatted text to an array of char, as opposed to a stream.

(For Childs Route Only such as /hello-world)

In the case you would like to make this kind of call :

/hello-world?foo=bar&fruit=banana

Angular2 doesn't use ? nor & but ; instead. So the correct URL should be :

/hello-world;foo=bar;fruit=banana

And to get those data :

import { Router, ActivatedRoute, Params } from '@angular/router';

private foo: string;
private fruit: string;

constructor(
  private route: ActivatedRoute,
  private router: Router
  ) {}

ngOnInit() {
  this.route.params.forEach((params: Params) => {
      this.foo = params['foo'];
      this.fruit = params['fruit'];
  });
  console.log(this.foo, this.fruit); // you should get your parameters here
}

Source : https://angular.io/docs/ts/latest/guide/router.html

in fact. use the methods of vector and index. we can also achieve the same result, and more easier to understand:

rawdata <- data.frame('time' = 1:3, 
           'x1' = 4:6,
           'x2' = 7:9,
           'x3' = 10:12)

rawdata[rep(1, time=2), ] %>% remove_rownames()
#  time x1 x2 x3
# 1    1  4  7 10
# 2    1  4  7 10

To view file (txt for example):

return File("~/TextFileInRootDir.txt", MediaTypeNames.Text.Plain);

To download file (txt for example):

return File("~/TextFileInRootDir.txt", MediaTypeNames.Text.Plain, "TextFile.txt");

note: to download file we should pass fileDownloadName argument

The only way to really do this (and is how the 'reallysimplehistory' does this), is by setting an interval that keeps checking the current hash, and comparing it against what it was before, we do this and let subscribers subscribe to a changed event that we fire if the hash changes.. its not perfect but browsers really don't support this event natively.

Update to keep this answer fresh:

If you are using jQuery (which today should be somewhat foundational for most) then a nice solution is to use the abstraction that jQuery gives you by using its events system to listen to hashchange events on the window object.

$(window).on('hashchange', function() {
  //.. work ..
});

The nice thing here is you can write code that doesn't need to even worry about hashchange support, however you DO need to do some magic, in form of a somewhat lesser known jQuery feature jQuery special events.

With this feature you essentially get to run some setup code for any event, the first time somebody attempts to use the event in any way (such as binding to the event).

In this setup code you can check for native browser support and if the browser doesn't natively implement this, you can setup a single timer to poll for changes, and trigger the jQuery event.

This completely unbinds your code from needing to understand this support problem, the implementation of a special event of this kind is trivial (to get a simple 98% working version), but why do that when somebody else has already.

This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.

1. Do pip install python-dotenv in your environment (the same as being pointed to by pycharm).

2. Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console

3. In "starting script" include something like this near the top:

   from dotenv import load_dotenv load_dotenv(verbose=True)

The .env file can look like this: export KEY=VALUE

It doesn't matter if one includes export or not for dotenv to read it.

As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.

The easiest way is to put the declaration and definition in the same file, but it may cause over-sized excutable file. E.g.

class Foo
{
public:
template <typename T> void some_method(T t) {//...}
}

Also, it is possible to put template definition in the separate files, i.e. to put them in .cpp and .h files. All you need to do is to explicitly include the template instantiation to the .cpp files. E.g.

// .h file
class Foo
{
public:
template <typename T> void some_method(T t);
}

// .cpp file
//...
template <typename T> void Foo::some_method(T t) 
{//...}
//...

template void Foo::some_method<int>(int);
template void Foo::some_method<double>(double);

The main difference is that the connection can be made via Unix Domain Socket, as stated here: localhost vs. 127.0.0.1

A number of processing symbols can be used when running several commands on the same line, and may lead to processing redirection in some cases, altering output in other case, or just fail. One important case is placing on the same line commands that manipulate variables.

@echo off
setlocal enabledelayedexpansion
set count=0
set "count=1" & echo %count% !count!

0 1

As you see in the above example, when commands using variables are placed on the same line, you must use delayed expansion to update your variable values. If your variable is indexed, use CALL command with %% modifiers to update its value on the same line:

set "i=5" & set "arg!i!=MyFile!i!" & call echo path!i!=%temp%\%%arg!i!%%

path5=C:\Users\UserName\AppData\Local\Temp\MyFile5

Add in your new column:

df$d <- list/data

Then you can reorder them.

df <- df[, c("a", "b", "d", "c")]

.val() always works with textarea elements.

.text() works sometimes and fails other times! It's not reliable (tested in Chrome 33)

What's best is that .val() works seamlessly with other form elements too (like input) whereas .text() fails.

If you can use jQuery, and I highly recommend you do, you would simply do

$('#myTextArea').val('');

Otherwise, it is browser dependent. Assuming you have

var myTextArea = document.getElementById('myTextArea');

In most browsers you do

myTextArea.innerHTML = '';

But in Firefox, you do

myTextArea.innerText = '';

Figuring out what browser the user is using is left as an exercise for the reader. Unless you use jQuery, of course ;)

Edit: I take that back. Looks like support for .innerHTML on textarea's has improved. I tested in Chrome, Firefox and Internet Explorer, all of them cleared the textarea correctly.

Edit 2: And I just checked, if you use .val('') in jQuery, it just sets the .value property for textarea's. So .value should be fine.

location.href = location.href + "&parameter=" + value;

On windows use the name of the table in quotes: TABLE "user"; or SELECT * FROM "user";

You can do it using only the shell, no need for tr or sed

$ str="This is just a test"
$ echo ${str// /_}
This_is_just_a_test

Using the Elastic search DSL API, you may hit the same error with

s = Search(using=client, index="my-index") \
    .query("match", category.keyword="Musician")

You can solve it by doing:

s = Search(using=client, index="my-index") \
    .query({"match": {"category.keyword":"Musician/Band"}})

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

Setting the Image property to null will work just fine. It will clear whatever image is currently displayed in the picture box. Make sure that you've written the code exactly like this:

picBox.Image = null;

I have some hacky answers that are likely to be terrible... but I have very little experience at this point.

a way:

class myClass():
    myInstances = []
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02
        self.__class__.myInstances.append(self)

myObj01 = myClass("Foo", "Bar")
myObj02 = myClass("FooBar",  "Baz")

for thisObj in myClass.myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

A hack way to get this done:

import sys
class myClass():
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02

myObj01 = myClass("Foo", "Bar")
myObj02 = myClass("FooBar",  "Baz")

myInstances = []
myLocals = str(locals()).split("'")
thisStep = 0
for thisLocalsLine in myLocals:
    thisStep += 1
    if "myClass object at" in thisLocalsLine:
        print(thisLocalsLine)
        print(myLocals[(thisStep - 2)])
        #myInstances.append(myLocals[(thisStep - 2)])
        print(myInstances)
        myInstances.append(getattr(sys.modules[__name__], myLocals[(thisStep - 2)]))

for thisObj in myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

Another more 'clever' hack:

import sys
class myClass():
    def __init__(self, myStr01, myStr02):
        self.myStr01 = myStr01
        self.myStr02 = myStr02

myInstances = []
myClasses = {
    "myObj01": ["Foo", "Bar"],
    "myObj02": ["FooBar",  "Baz"]
    }

for thisClass in myClasses.keys():
    exec("%s = myClass('%s', '%s')" % (thisClass, myClasses[thisClass][0], myClasses[thisClass][1]))
    myInstances.append(getattr(sys.modules[__name__], thisClass))

for thisObj in myInstances:
    print(thisObj.myStr01)
    print(thisObj.myStr02)

AFAIK, there is no way to do this reliably, unless you switch to an array. Which honestly, doesn't seem strange - it's seems pretty straight forward to me that arrays are countable, and objects aren't.

Probably the closest you'll get is something like this

// Monkey patching on purpose to make a point
Object.prototype.length = function()
{
  var i = 0;
  for ( var p in this ) i++;
  return i;
}

alert( {foo:"bar", bar: "baz"}.length() ); // alerts 3

But this creates problems, or at least questions. All user-created properties are counted, including the _length function itself! And while in this simple example you could avoid it by just using a normal function, that doesn't mean you can stop other scripts from doing this. so what do you do? Ignore function properties?

Object.prototype.length = function()
{
  var i = 0;
  for ( var p in this )
  {
      if ( 'function' == typeof this[p] ) continue;
      i++;
  }
  return i;
}

alert( {foo:"bar", bar: "baz"}.length() ); // alerts 2

In the end, I think you should probably ditch the idea of making your objects countable and figure out another way to do whatever it is you're doing.

I really like line-clamp, but no support for firefox yet.. so i go with a math calc and just hide the overflow

.body-content.body-overflow-hidden h5 {
    max-height: 62px;/* font-size * line-height * lines-to-show(4 in this case) 63px if you go with jquery */
    overflow: hidden;
}
.body-content h5 {
    font-size: 14px; /* need to know this*/
    line-height:1,1; /*and this*/
}

now lets say you want to remove and add this class via jQuery with a link, you will need to have an extra pixel so the max-height it will be 63 px, this is because you need to check every time if the height greather than 62px, but in the case of 4 lines you will get a false true, so an extra pixel will fix this and it will no create any extra problems

i will paste a coffeescript for this just to be an example, uses a couple of links that are hidden by default, with classes read-more and read-less, it will remove the ones that the overflow is not need it and remove the body-overflow classes

jQuery ->

    $('.read-more').each ->
        if $(this).parent().find("h5").height() < 63
             $(this).parent().removeClass("body-overflow-hidden").find(".read-less").remove()
             $(this).remove()
        else
            $(this).show()

    $('.read-more').click (event) ->
        event.preventDefault()
        $(this).parent().removeClass("body-overflow-hidden")
        $(this).hide()
        $(this).parent().find('.read-less').show()

    $('.read-less').click (event) ->
        event.preventDefault()
        $(this).parent().addClass("body-overflow-hidden")
        $(this).hide()
        $(this).parent().find('.read-more').show()

You might set location directly because it's slightly shorter. If you're trying to be terse, you can usually omit the window. too.

URL assignments to both location.href and location are defined to work in JavaScript 1.0, back in Netscape 2, and have been implemented in every browser since. So take your pick and use whichever you find clearest.

As, you mentioned pContext.getParent().getPropertyValue return Set. You can convert Set to List to get the first element. Just change your code like:

 Set<String> siteIdSet = (Set<String>) pContext.getParent().getPropertyValue(..);
 List<String> siteIdList=new ArrayList<>(siteIdSet);

 String firstItem=siteIdList.get(0);

I always use Moment.js when I need to use dates for any reason.

Try this:

import { Pipe, PipeTransform } from '@angular/core'
import * as moment from 'moment'

@Pipe({
   name: 'formatDate'
})
export class DatePipe implements PipeTransform {
   transform(date: any, args?: any): any {
     let d = new Date(date)
     return moment(d).format('DD/MM/YYYY')

   }
}

And in the view:

<p>{{ date | formatDate }}</p>

2019's answer as this is still actively seen today

You should likely change the .container to .container-fluid, which will cause your container to stretch the entire screen. This will allow any div's inside of it to naturally stretch as wide as they need.

original hack from 2015 that still works in some situations

You should pull that div outside of the container. You're asking a div to stretch wider than its parent, which is generally not recommended practice.

If you cannot pull it out of the div for some reason, you should change the position style with this css:

.full-width-div {
    position: absolute;
    width: 100%;
    left: 0;
}

Instead of absolute, you could also use fixed, but then it will not move as you scroll.

You can use GNU Parallel for this as it works as a mutex when called as sem. So, in concrete terms, you can use:

sem --id SCRIPTSINGLETON yourScript

If you want a timeout too, use:

sem --id SCRIPTSINGLETON --semaphoretimeout -10 yourScript

Timeout of <0 means exit without running script if semaphore is not released within the timeout, timeout of >0 mean run the script anyway.

Note that you should give it a name (with --id) else it defaults to the controlling terminal.

GNU Parallel is a very simple install on most Linux/OSX/Unix platforms - it is just a Perl script.

For frame:

height=fr.getHeight();
width=fr.getWidth();

For screen:

width = getWindowManager().getDefaultDisplay().getWidth();
height = getWindowManager().getDefaultDisplay().getHeight();

Wow, this problem is popular. It's based on a misunderstanding in the vertical-align property. This excellent article explains it:

Understanding vertical-align, or "How (Not) To Vertically Center Content" by Gavin Kistner.

“How to center in CSS” is a great web tool which helps to find the necessary CSS centering attributes for different situations.

In a nutshell _{^{(and to prevent link rot)}}:

• Inline elements (and only inline elements) can be vertically aligned in their context via vertical-align: middle. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle example
• For block elements, vertical alignment is harder and strongly depends on the specific situation:
  • If the inner element can have a fixed height, you can make its position absolute and specify its height, margin-top and top position. jsfiddle example
  • If the centered element consists of a single line and its parent height is fixed you can simply set the container’s line-height to fill its height. This method is quite versatile in my experience. jsfiddle example
  • … there are more such special cases.

Here's what worked for me.

Html using the directive

 <tr orderitemdirective remove="vm.removeOrderItem(orderItem)" order-item="orderitem"></tr>

Html of the directive: orderitem.directive.html

<md-button type="submit" ng-click="remove({orderItem:orderItem})">
       (...)
</md-button>

Directive's scope:

scope: {
    orderItem: '=',
    remove: "&",

Strings are immutable, so when you manipulate them you need to assign the result to a string:

String id = fileR.getName();
id = id.replace(".xml", ""); // this is the key line
idList.add(id);

As of Django 1.9, the way to do this is by using __date on a datetime object.

For example: MyObject.objects.filter(datetime_attr__date=datetime.date(2009,8,22))

Adding to the other great answers, we can use the Python logging library's debug(), info(), warning(), error(), and critical() methods. Quoting from the docs for Python 3.7.4,

There are three keyword arguments in kwargs which are inspected: exc_info which, if it does not evaluate as false, causes exception information to be added to the logging message.

What this means is, you can use the Python logging library to output a debug(), or other type of message, and the logging library will include the stack trace in its output. With this in mind, we can do the following:

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

def f():
    a = { 'foo': None }
    # the following line will raise KeyError
    b = a['bar']

def g():
    f()

try:
    g()

All solutions including the accepted one have some issues as stated in their respective comments. The accepted answer by @jonathan-leffler is already quite good but does not take into effect that prerequisites are not necessarily to be built in order (during make -j for example). However simply moving the directories prerequisite from all to program provokes rebuilds on every run AFAICT. The following solution does not have that problem and AFAICS works as intended.

MKDIR_P := mkdir -p
OUT_DIR := build

.PHONY: directories all clean

all: $(OUT_DIR)/program

directories: $(OUT_DIR)

$(OUT_DIR):
    ${MKDIR_P} $(OUT_DIR)

$(OUT_DIR)/program: | directories
    touch $(OUT_DIR)/program

clean:
    rm -rf $(OUT_DIR)

EDIT: This answer might be outdated if you're using a recent version of jQueryUI.

For an anchor to trigger the dialog -

<a href="http://ibm.com" class="example">

Here's the script -

$('a.example').click(function(){   //bind handlers
   var url = $(this).attr('href');
   showDialog(url);

   return false;
});

$("#targetDiv").dialog({  //create dialog, but keep it closed
   autoOpen: false,
   height: 300,
   width: 350,
   modal: true
});

function showDialog(url){  //load content and open dialog
    $("#targetDiv").load(url);
    $("#targetDiv").dialog("open");         
}

In the webpack.config.js:

module.exports = {
  ......
  devServer: {
    historyApiFallback: true,
    port: 8081,   // you can change the port there
    noInfo: true,
    overlay: true
  },
  ......
}

You can change the port in the module.exports -> devServer -> port.

Then you restrat the npm run dev. You can get that.

By default session object is available on jsp page(implicit object). It will not available in normal POJO java class. You can get the reference of HttpSession object on Servelt by using HttpServletRequest

HttpSession s=request.getSession()
s.setAttribute("name","value");

You can get session on an ActionSupport based Action POJO class as follows

 ActionContext ctx= ActionContext.getContext();
   Map m=ctx.getSession();
   m.put("name", value);

look at: http://ohmjavaclasses.blogspot.com/2011/12/access-session-in-action-class-struts2.html

this code worked for me to re-instantiate the event after i had used :

event.preventDefault(); to disable the event.


event.preventDefault = false;

Right now there is no view:clear command. For laravel 4 this can probably help you: https://gist.github.com/cjonstrup/8228165

Disabling caching can be done by skipping blade. View caching is done because blade compiling each time is a waste of time.

Unsupported major.minor version 52.0 comes when you are trying to run a class compiled using Java 1.8 compiler into a lower JRE version e.g. JRE 1.7 or JRE 1.6. Simplest way to fix this error is install the latest Java release i.e. Java 8 and run your program.

You can install ECMerge diff/merge tool on your Linux, Mac or Windows. It is pre-configured in Git, so just using git mergetool will do the job.

$num = 10;
"'".$num."'"

Try this

In my case here, I had several .lock files in several directories that I needed to remove. I ran the following and it worked without having to go into each directory to remove them:

git rm -r --cached **/*.lock

Doing this went into each folder under the 'root' of where I was at and excluded all files that matched the pattern.

Hope this helps others!

You may use closest() in modern browsers:

var div = document.querySelector('div#myDiv');
div.closest('div[someAtrr]');

Use object detection to supply a polyfill or alternative method for backwards compatability with IE.

Is one just an extension?

Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The RFC also has some small, subtle differences. For example truncated representations of years with only two digits are not allowed -- RFC 3339 requires 4-digit years, and the RFC only allows a period character to be used as the decimal point for fractional seconds. The RFC also allows the "T" to be replaced by a space (or other character), while the standard only allows it to be omitted (and only when there is agreement between all parties using the representation).

I wouldn't worry too much about the differences between the two, but on the off-chance your use case runs in to them, it'd be worth your while taking a glance at:

• RFC 3339
• Wikipedia entry on ISO 8601

I was stuck with the same problem. I found this page with all the possible versions of the KB2999226 also know as Update for Universal C Runtime in Windows.

https://support.microsoft.com/en-au/kb/2999226

I download the x64 version and it work perfectly in my Windows 7 Ultimate.

BreedId in the Dog table is obviously a foreign key to the corresponding row in the Breed table. If you've got your database set up properly, LINQ to SQL should automatically create an association between the two tables. The resulting Dog class will have a Breed property, and the Breed class should have a Dogs collection. Setting it up this way, you can still return IEnumerable<Dog>, which is an object that includes the breed property. The only caveat is that you need to preload the breed object along with dog objects in the query so they can be accessed after the data context has been disposed, and (as another poster has suggested) execute a method on the collection that will cause the query to be performed immediately (ToArray in this case):

public IEnumerable<Dog> GetDogs()
{
    using (var db = new DogDataContext(ConnectString))
    {
        db.LoadOptions.LoadWith<Dog>(i => i.Breed);
        return db.Dogs.ToArray();
    }

}

It is then trivial to access the breed for each dog:

foreach (var dog in GetDogs())
{
    Console.WriteLine("Dog's Name: {0}", dog.Name);
    Console.WriteLine("Dog's Breed: {0}", dog.Breed.Name);        
}

Using only nltk tools

from nltk.tokenize import word_tokenize
from nltk.util import ngrams

def get_ngrams(text, n ):
    n_grams = ngrams(word_tokenize(text), n)
    return [ ' '.join(grams) for grams in n_grams]

Example output

get_ngrams('This is the simplest text i could think of', 3 )

['This is the', 'is the simplest', 'the simplest text', 'simplest text i', 'text i could', 'i could think', 'could think of']

In order to keep the ngrams in array format just remove ' '.join

Originally, this was geared towards finding out the latest commit of a remote branch (not just from your last fetch, but the actual latest commit in the branch on the remote repository). If you need the commit hash for something locally, the best answer is:

git rev-parse branch-name

It's fast, easy, and a single command. If you want the commit hash for the current branch, you can look at HEAD:

git rev-parse HEAD

In jQuery, when you handle the click event, return false to stop the link from responding the usual way prevent the default action, which is to visit the href attribute, from taking place (per PoweRoy's comment and Erik's answer):

$('a.someclass').click(function(e)
{
    // Special stuff to do when this link is clicked...

    // Cancel the default action
    e.preventDefault();
});

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Attributes.Add("style", "cursor:help;");
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Alternate)
    { 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {                
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#E56E94'");
            e.Row.BackColor = Color.FromName("#E56E94");                
        }           
    }
    else
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='gray'");
            e.Row.BackColor = Color.FromName("gray");                
        }           
    }
}

Short Answer

Use the -s option:

pytest -s

Detailed answer

From the docs:

During test execution any output sent to stdout and stderr is captured. If a test or a setup method fails its according captured output will usually be shown along with the failure traceback.

pytest has the option --capture=method in which method is per-test capturing method, and could be one of the following: fd, sys or no. pytest also has the option -s which is a shortcut for --capture=no, and this is the option that will allow you to see your print statements in the console.

pytest --capture=no     # show print statements in console
pytest -s               # equivalent to previous command

Setting capturing methods or disabling capturing

There are two ways in which pytest can perform capturing:

1. file descriptor (FD) level capturing (default): All writes going to the operating system file descriptors 1 and 2 will be captured.

2. sys level capturing: Only writes to Python files sys.stdout and sys.stderr will be captured. No capturing of writes to filedescriptors is performed.

pytest -s            # disable all capturing
pytest --capture=sys # replace sys.stdout/stderr with in-mem files
pytest --capture=fd  # also point filedescriptors 1 and 2 to temp file

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).

With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.

We'll take an example, a company table with a user table containing people from theses company

CREATE TABLE COMPANY (
     company_id INT NOT NULL,
     company_name VARCHAR(50),
     PRIMARY KEY (company_id)
) ENGINE=INNODB;

CREATE TABLE USER (
     user_id INT, 
     user_name VARCHAR(50), 
     company_id INT,
     INDEX company_id_idx (company_id),
     FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;

Let's look at the ON UPDATE clause:

• ON UPDATE RESTRICT : the default : if you try to update a company_id in table COMPANY the engine will reject the operation if one USER at least links on this company.
• ON UPDATE NO ACTION : same as RESTRICT.
• ON UPDATE CASCADE : the best one usually : if you update a company_id in a row of table COMPANY the engine will update it accordingly on all USER rows referencing this COMPANY (but no triggers activated on USER table, warning). The engine will track the changes for you, it's good.
• ON UPDATE SET NULL : if you update a company_id in a row of table COMPANY the engine will set related USERs company_id to NULL (should be available in USER company_id field). I cannot see any interesting thing to do with that on an update, but I may be wrong.

And now on the ON DELETE side:

• ON DELETE RESTRICT : the default : if you try to delete a company_id Id in table COMPANY the engine will reject the operation if one USER at least links on this company, can save your life.
• ON DELETE NO ACTION : same as RESTRICT
• ON DELETE CASCADE : dangerous : if you delete a company row in table COMPANY the engine will delete as well the related USERs. This is dangerous but can be used to make automatic cleanups on secondary tables (so it can be something you want, but quite certainly not for a COMPANY<->USER example)
• ON DELETE SET NULL : handful : if you delete a COMPANY row the related USERs will automatically have the relationship to NULL. If Null is your value for users with no company this can be a good behavior, for example maybe you need to keep the users in your application, as authors of some content, but removing the company is not a problem for you.

usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.

Edit

It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.

• http://dev.mysql.com/doc/refman/5.6/en/triggers.html

MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server

• http://dev.mysql.com/doc/refman/5.6/en/stored-program-restrictions.html#stored-routines-trigger-restrictions

==> See below the last edit, things are moving on this domain

Triggers are not activated by foreign key actions.

And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.

But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.

12/2017-Updating this Edit about MySQL:

as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).

In jQuery:

var html_string = $('html').outerHTML()

In plain Javascript:

var html_string = document.documentElement.outerHTML

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

You might consider Digest Access Authentication. Essentially the protocol is as follows:

1. Request is made from client
2. Server responds with a unique nonce string
3. Client supplies a username and password (and some other values) md5 hashed with the nonce; this hash is known as HA1
4. Server is then able to verify client's identity and serve up the requested materials
5. Communication with the nonce can continue until the server supplies a new nonce (a counter is used to eliminate replay attacks)

All of this communication is made through headers, which, as jmort253 points out, is generally more secure than communicating sensitive material in the url parameters.

Digest Access Authentication is supported by Spring Security. Notice that, although the docs say that you must have access to your client's plain-text password, you can successfully authenticate if you have the HA1 hash for your client.

ByteArrayInputStream extends InputStream:

InputStream myInputStream = new ByteArrayInputStream(myBytes); 

That's should show the difference between the two dates in minutes. Try it in your browser:

const currDate = new Date('Tue Feb 13 2018 13:04:58 GMT+0200 (EET)')
const oldDate  = new Date('Tue Feb 13 2018 12:00:58 GMT+0200 (EET)')


(currDate - oldDate) / 60000 // 64

You need to do custom SQL as exemplified in this snippet:

Custom SQL via subquery

Or in a custom manager as shown in the online Django docs:

Adding extra Manager methods

try the + symbol: It is Adjacent sibling combinator. It combines two sequences of simple selectors having the same parent and the second one must come IMMEDIATELY after the first.

As such:

input[type="radio"]:checked+label{ font-weight: bold; } 
 //a label that immediately follows an input of type radio that is checked 

works very nicely for the following markup:

<input id="rad1" type="radio" name="rad"/><label for="rad1">Radio 1</label>
<input id="rad2" type="radio" name="rad"/><label for="rad2">Radio 2</label>

... and it will work for any structure, with or without divs etc as long as the label follows the radio input.

Example:

input[type="radio"]:checked+label { font-weight: bold; }

<input id="rad1" type="radio" name="rad"/><label for="rad1">Radio 1</label>_x000D_
<input id="rad2" type="radio" name="rad"/><label for="rad2">Radio 2</label>

Very neat trick I stumble upon trying some SQL injection, in object explorer in the search box just use your percentage characters, and this will search EVERYTHING stored procedures, functions, views, tables, schema, indexes...I tired of thinking of more :)

For me this simple command solved the problem:

sudo apt-get install postgresql postgresql-contrib libpq-dev python-dev

Then I can do:

Updated for Swift 3 and above:

//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)

//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
    textField.text = "Some default text"
}

// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in

Assuming you want an action alert on iOS:

//1. Create the alert controller.            
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)

//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
    textField.text = "Some default text."
})

//3. Grab the value from the text field, and print it when the user clicks OK. 
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
    let textField = alert.textFields![0] as UITextField
    println("Text field: \(textField.text)")

Try using type:

type foobar

For example:

$ type ls
ls is aliased to `ls --color=auto'

$ type foobar
-bash: type: foobar: not found

This is preferable to which for a few reasons:

1. The default which implementations only support the -a option that shows all options, so you have to find an alternative version to support aliases

2. type will tell you exactly what you are looking at (be it a Bash function or an alias or a proper binary).

3. type doesn't require a subprocess

4. type cannot be masked by a binary (for example, on a Linux box, if you create a program called which which appears in path before the real which, things hit the fan. type, on the other hand, is a shell built-in (yes, a subordinate inadvertently did this once).

I can elaborate on the details of DLLs in Windows to help clarify those mysteries to my friends here in *NIX-land...

A DLL is like a Shared Object file. Both are images, ready to load into memory by the program loader of the respective OS. The images are accompanied by various bits of metadata to help linkers and loaders make the necessary associations and use the library of code.

Windows DLLs have an export table. The exports can be by name, or by table position (numeric). The latter method is considered "old school" and is much more fragile -- rebuilding the DLL and changing the position of a function in the table will end in disaster, whereas there is no real issue if linking of entry points is by name. So, forget that as an issue, but just be aware it's there if you work with "dinosaur" code such as 3rd-party vendor libs.

Windows DLLs are built by compiling and linking, just as you would for an EXE (executable application), but the DLL is meant to not stand alone, just like an SO is meant to be used by an application, either via dynamic loading, or by link-time binding (the reference to the SO is embedded in the application binary's metadata, and the OS program loader will auto-load the referenced SO's). DLLs can reference other DLLs, just as SOs can reference other SOs.

In Windows, DLLs will make available only specific entry points. These are called "exports". The developer can either use a special compiler keyword to make a symbol an externally-visible (to other linkers and the dynamic loader), or the exports can be listed in a module-definition file which is used at link time when the DLL itself is being created. The modern practice is to decorate the function definition with the keyword to export the symbol name. It is also possible to create header files with keywords which will declare that symbol as one to be imported from a DLL outside the current compilation unit. Look up the keywords __declspec(dllexport) and __declspec(dllimport) for more information.

One of the interesting features of DLLs is that they can declare a standard "upon load/unload" handler function. Whenever the DLL is loaded or unloaded, the DLL can perform some initialization or cleanup, as the case may be. This maps nicely into having a DLL as an object-oriented resource manager, such as a device driver or shared object interface.

When a developer wants to use an already-built DLL, she must either reference an "export library" (*.LIB) created by the DLL developer when she created the DLL, or she must explicitly load the DLL at run time and request the entry point address by name via the LoadLibrary() and GetProcAddress() mechanisms. Most of the time, linking against a LIB file (which simply contains the linker metadata for the DLL's exported entry points) is the way DLLs get used. Dynamic loading is reserved typically for implementing "polymorphism" or "runtime configurability" in program behaviors (accessing add-ons or later-defined functionality, aka "plugins").

The Windows way of doing things can cause some confusion at times; the system uses the .LIB extension to refer to both normal static libraries (archives, like POSIX *.a files) and to the "export stub" libraries needed to bind an application to a DLL at link time. So, one should always look to see if a *.LIB file has a same-named *.DLL file; if not, chances are good that *.LIB file is a static library archive, and not export binding metadata for a DLL.

Try this:

table {
    border-collapse: separate;
    border-spacing: 10px;
}
table td, table th {
    padding: 10px;
}

Or try this:

table {
    border-collapse: collapse;
}
table td, table th {
    padding: 10px;
}

Try this. Simple yet effective javaScript + jQuery the lethal combo.

SelectComponent :

<select id="YourSelectComponentID">
            <option value="0">Apple</option>
            <option value="2">Banana</option>
            <option value="3">Cat</option>
            <option value="4">Dolphin</option>
</select>

Selection :

document.getElementById("YourSelectComponentID").value = 4;

Now your option 4 will be selected. You can do this, to select the values on start by default.

$(function(){
   document.getElementById("YourSelectComponentID").value = 4;
});

or create a simple function put the line in it and call the function on anyEvent to select the option

A mixture of jQuery + javaScript does the magic....

if you are using bootstrap time picker. use showMeridian property to make the time picker 24 hours format.

$('.time-picker').timepicker({
            showMeridian: false     
        });

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return UniversityDetails.objects.get(email__exact=email)
    except UniversityDetails.DoesNotExist:
        return False

Unfortunately, setTimeout() is the only reliable way (not the only way, but the only reliable way) to pause the execution of the script without blocking the UI.

It's not that hard to use actually, instead of writing this:

var x = 1;

// Place mysterious code that blocks the thread for 100 ms.

x = x * 3 + 2;
var y = x / 2;

you use setTimeout() to rewrite it this way:

var x = 1;
var y = null; // To keep under proper scope

setTimeout(function() {
    x = x * 3 + 2;
    y = x / 2;
}, 100);

I understand that using setTimeout() involves more thought than a desirable sleep() function, but unfortunately the later doesn't exist. Many workarounds are there to try to implement such functions. Some using busy loops:

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

others using an XMLHttpRequest tied with a server script that sleeps for a amount of time before returning a result.

Unfortunately, those are workarounds and are likely to cause other problems (such as freezing browsers). It is recommended to simply stick with the recommended way, which is setTimeout()).

Don't worry just change the

build.gradle
   ext.kotlin_version = '1.2.41'

to previous version. It worked for me hope it works for you too. Happy coding.

In 3.2 and later, Python saves .pyc compiled byte code files in a sub-directory named __pycache__ located in the directory where your source files reside with filenames that identify the Python version that created them (e.g. script.cpython-33.pyc)

No. Order is not guaranteed in JSON and most other key-value data structures, so therefore the last item could sometimes be carrot and at other times be banana and so on. If you need to rely on ordering, your best bet is to go with arrays. The power of key-value data structures lies in accessing values by their keys, not in being able to get the nth item of the object.

You can create with javascript some css-rules, which you can later use in your styles: http://jsfiddle.net/ARTsinn/vKbda/

var addRule = (function (sheet) {
    if(!sheet) return;
    return function (selector, styles) {
        if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
        if (sheet.addRule) return sheet.addRule(selector, styles);
    }
}(document.styleSheets[document.styleSheets.length - 1]));

var i = 101;
while (i--) {
    addRule("[data-width='" + i + "%']", "width:" + i + "%");
}

This creates 100 pseudo-selectors like this:

[data-width='1%'] { width: 1%; }
[data-width='2%'] { width: 2%; }
[data-width='3%'] { width: 3%; }
...
[data-width='100%'] { width: 100%; }

Note: This is a bit offtopic, and not really what you (or someone) wants, but maybe helpful.

Since you are still getting duplicate using only UNION I would check that:

• That they are exact duplicates. I mean, if you make a

  SELECT DISTINCT * FROM (<your query>) AS subquery

  you do get fewer files?

• That you don't have already the duplicates in the first part of the query (maybe generated by the left join). As I understand it UNION it will not add to the result set rows that are already on it, but it won't remove duplicates already present in the first data set.

When you export you use the compatibility system set to MYSQL40. Worked for me.

May be this examples help to you

Compile file, run and delete after (my preference)

$ gcc timeout.c -o timeout && ./timeout && rm timeout

Try run it for yourself to see result.

In phpMyAdmin v.4.6.5.2 there's a checkbox option "The first line of the file contains the table column names...." :

We can Supply parameter in different way after some search I found some useful

<plugin>
  <artifactId>${release.artifactId}</artifactId>
  <version>${release.version}-${release.svm.version}</version>...

...

Actually in my application I need to save and supply SVN Version as parameter so i have implemented as above .

While Running build we need supply value for those parameter as follows.

RestProj_Bizs>mvn clean install package -Drelease.artifactId=RestAPIBiz -Drelease.version=10.6 -Drelease.svm.version=74

Here I am supplying

release.artifactId=RestAPIBiz
release.version=10.6
release.svm.version=74

It worked for me. Thanks

Thanks Jamie Bullock this Work for me

As per Jamie Bullock,

I just had this problem, and the cause seemed to be that a directory had been flagged as in conflict. To fix:

1. svn update
2. svn resolved
3. svn commit

You can use Vim:

vim my.jar

Vim is able to edit compressed text files, given you have unzip in your environment.

Just use xcopy /y source destination

To copy remote-to-remote files you can use the synchronize module with 'delegate_to: source-server' keyword:

- hosts: serverB
  tasks:    
   - name: Copy Remote-To-Remote (from serverA to serverB)
     synchronize: src=/copy/from_serverA dest=/copy/to_serverB
     delegate_to: serverA

This playbook can run from your machineC.

Switch in combination with variable variables will give you more flexibility:

<?php
$p = 'home'; //For testing

$p = ( strpos($p, 'users') !== false? 'users': $p);
switch ($p) { 
    default:
        $varContainer = 'current_' . $p; //Stores the variable [$current_"xyORz"] into $varContainer
        ${$varContainer} = 'current'; //Sets the VALUE of [$current_"xyORz"] to 'current'
    break;

}
//For testing
echo $current_home;
?>

To learn more, checkout variable variables and the examples I submitted to php manual:
Example 1: http://www.php.net/manual/en/language.variables.variable.php#105293
Example 2: http://www.php.net/manual/en/language.variables.variable.php#105282

PS: This example code is SMALL AND SIMPLE, just the way I like it. It's tested and works too

REMEMBER, this method overwrites first array, so use only when you are sure!

$arr1 = $arr1 + $arr2;

(see source)

Choose your poison - if you can't change the type of the property to be nullable then you're going to have to use a "magic" value to represent NULL. Guid.Empty seems as good as any unless you have some specific reason for not wanting to use it. A second choice would be Guid.Parse("ffffffff-ffff-ffff-ffff-ffffffffffff") but that's a lot uglier IMHO.

Here you go:

function neat_trim($str, $n, $delim='…') {
   $len = strlen($str);
   if ($len > $n) {
       preg_match('/(.{' . $n . '}.*?)\b/', $str, $matches);
       return rtrim($matches[1]) . $delim;
   }
   else {
       return $str;
   }
}

There are many ways to do that. For example:

lst = [1,2,3,4,5,6]
[(lst[i], lst[i+1]) for i,_ in enumerate(lst[:-1])]    
>>>[(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)]

[i for i in zip(*[iter(lst)]*2)]    
>>>[(1, 2), (3, 4), (5, 6)]

No, you can only get to the interior color of a cell by using a Macro. I am afraid. It's really easy to do (cell.interior.color) so unless you have a requirement that restricts you from using VBA, I say go for it.

re.sub is definitely what you are looking for. And so you know, you don't need the anchors and the wildcards.

re.sub(r"(?i)interfaceOpDataFile", "interfaceOpDataFile %s" % filein, line)

will do the same thing--matching the first substring that looks like "interfaceOpDataFile" and replacing it.

Sometimes it is due to the master table is dropped (maybe by disabling foreign_key_checks), but the foreign key CONSTRAINT still exists in other tables. In my case I had dropped the table and tried to recreate it, but it was throwing the same error for me.

So try dropping all the foreign key CONSTRAINTs from all the tables if there are any and then update or create the table.

It depends upon the context. Some possible contexts in HTML:

• document body
• inside common attributes
• inside script tags
• inside style tags
• several more!

See OWASP's Cross Site Scripting Prevention Cheat Sheet, especially the "Why Can't I Just HTML Entity Encode Untrusted Data?" and "XSS Prevention Rules" sections. However, it's best to read the whole document.

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

Modern solution

Flexbox was created for exactly these kind of problems:

#container {_x000D_
    height: 150px;/*Only for the demo.*/_x000D_
    background-color:green;/*Only for the demo.*/_x000D_
    display: flex;_x000D_
    justify-content: center;_x000D_
    align-items: flex-end;_x000D_
}

<div id="container">_x000D_
    <span>Text align to center bottom.</span>_x000D_
</div>

Old school solution

If you don't want to mess with table displays, then you can create a <div> inside a relatively positioned parent container, place it to the bottom with absolute positioning, then make it 100% wide, so you can text-align it to the center:

#container {_x000D_
    height: 150px;/*Only for the demo.*/_x000D_
    background-color:green;/*Only for the demo.*/_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
#text {_x000D_
    position: absolute;_x000D_
    bottom: 0;_x000D_
    width: 100%;_x000D_
    text-align: center;_x000D_
}

<div id="container">_x000D_
    <span id="text">Text align to center bottom.</span>_x000D_
</div>

We can sort() function to sort string array.

Procedure :

1. At first determine the size string array.

2. use sort function . sort(array_name, array_name+size)

3. Iterate through string array/

Code Snippet

#include<bits/stdc++.h>
using namespace std;

int main()
{
    ios::sync_with_stdio(false);

    string name[] = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    int len = sizeof(name)/sizeof(name[0]);

    sort(name, name+len);

    for(string n: name)
    {
         cout<<n<<" ";
    }
    cout<<endl;

    return 0;
}

If you're in ipython in pylab mode, then

plt.gca().invert_yaxis()
show()

the show() is required to make it update the current figure.

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>

        sleep(1);
    }

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

select count(*) from(select count(SID) from Test where Date = '2012-12-10' group by SID)select count(*) from(select count(SID) from Test where Date = '2012-12-10' group by SID)

should works

You can do like this:

 String hello;
public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.main);
    super.onCreate(savedInstanceState);

    mybtn = (Button)findViewById(R.id.mybtn);
    txtView=(TextView)findViewById(R.id.txtView);
    txtwidth = (TextView)findViewById(R.id.viewwidth);
    hello="This is my first project";


    mybtn.setOnClickListener(this);
}
public void onClick(View view){
    txtView.setText(hello);
}

Check your textview names. Both are same . You must use different object names and you have mentioned that textview object which is not available in your xml layout file. Hope this will help you.

You can install andle for gradle version management.

It can help you sync to the latest version almost everything in gradle file.

Simple three step to update all project at once.

1. install:

    $ sudo pip install andle

2. set sdk:

    $ andle setsdk -p <sdk_path>

3. update depedency:

    $ andle update -p <project_path> [--dryrun] [--remote] [--gradle]

--dryrun: only print result in console

I think you are looking for Return instead of Break. Break is typically used for loops and only breaks from the innermost code block. Use Return to exit a function or script.

That helped me with my code.

When I tried feltering only a type of files and show them on screen by adding a condition that tests on each line.

Like this

elif command == 'ls':
    print("directory of ", ftp.pwd())
    data = []
    ftp.dir(data.append)

    for line in data:
        x = line.split(".")
        formats=["gz", "zip", "rar", "tar", "bz2", "xz"]
        if x[-1] in formats:
            print ("-", line)

In addition to the accepted answer, I want to give you an example!

For instance, we all use

System.Console.WriteLine()

But Where is the code for System.Console.WriteLine!?
which is the code that actually puts the text on the console?

If you look at the first page of the documentation for the Console class, you‘ll see near the top the following: Assembly: mscorlib (in mscorlib.dll) This indicates that the code for the Console class is located in an assem-bly named mscorlib. An assembly can consist of multiple files, but in this case it‘s only one file, which is the dynamic link library mscorlib.dll.

The mscorlib.dll file is very important in .NET, It is the main DLL for class libraries in .NET, and it contains all the basic .NET classes and structures.

if you know C or C++, generally you need a #include directive at the top that references a header file. The include file provides function prototypes to the compiler. on the contrast The C# compiler does not need header files. During compilation, the C# compiler access the mscorlib.dll file directly and obtains information from metadata in that file concerning all the classes and other types defined therein.

The C# compiler is able to establish that mscorlib.dll does indeed contain a class named Console in a namespace named System with a method named WriteLine that accepts a single argument of type string.

The C# compiler can determine that the WriteLine call is valid, and the compiler establishes a reference to the mscorlib assembly in the executable.

by default The C# compiler will access mscorlib.dll, but for other DLLs, you‘ll need to tell the compiler the assembly in which the classes are located. These are known as references.

I hope that it's clear now!

From DotNetBookZero Charles pitzold

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

Check whether you are scheduling a task to trigger an executable (.exe) or a batch (.bat) file. If you have scheduled any other file to open (for example a .txt or .docx file), the file not open.

If none of the above method worked then try this it worked for me.

Go to File > Project Structure> Project and then in Project Compiler Output click on the three dots and provide the path of your project name(name of the file) and then click on Apply and than on Ok.

The other answers are several years old (and do not work for Windows Phone 8.1) so I figured I'd drop in another option. I used this to parse an RSS response for a Windows Phone app:

XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(xml_string);

Both, FILL_PARENT and MATCH_PARENT are the same properties. FILL_PARENT was deprecated in API level 8.

If your site is not live yet, and you just want to update the stylesheet at your pleased intervals, then use this:

Ctrl + F5

This will force your browser to reload and refresh all the resources related to the website's page.

So everytime you change something in your stylesheet and you wanna view the new results, use this.

On Mac OS Chrome use: Command + Shift + R.

In page header, add

<meta name="viewport" content="width=device-width, initial-scale=1, minimum-sacle=1, maximum-scale=1, user-scalable=no">

In page stylesheet, add

html, body {
  overflow-x: hidden;
  overflow-y: hidden;
}

It is both html and body!

2014 March: Truncating long strings with CSS: a new answer with focus on browser support

Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).

<style type="text/css">
    span {
        display: inline-block;
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;     /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
        -o-text-overflow: ellipsis;  /** Opera 9 & 10 **/
        width: 370px; /* note that this width will have to be smaller to see the effect */
    }
</style>

<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>

The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.

Successfully tested (on Browserstack.com) on Windows OS, for web browsers:

• IE6 to IE11
• Opera 10.6, Opera 11.1, Opera 15.0, Opera 20.0
• Chrome 14, Chrome 20, Chrome 25
• Safari 4.0, Safari 5.0, Safari 5.1
• Firefox 7.0, Firefox 15

Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).

I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).

Some further testing on a Mac OS web browsers would be needed.

Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated

This is also easy:

string data = "THExxQUICKxxBROWNxxFOX";
string[] arr = data.Split("xx".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

what if your wrapping div was 100% and you used padding for a pixel amount, then if the padding # needs to be dynamic, you can easily use jQuery to modify your padding amount when your events fire.

You can find your sample code completely here: http://www.java2s.com/Code/Java/Hibernate/OneToManyMappingbasedonSet.htm

Have a look and check the differences. specially the even_id in :

<set name="attendees" cascade="all">
    <key column="event_id"/>
    <one-to-many class="Attendee"/>
</set> 

SELECT *
INTO newtable [IN externaldb]
FROM table1;

Probably very late to the answer but I just read this while preparing for my 70-480 exam, and found this to work -

var elem = document.getElementById('myCanvas');
elem.onclick = function() { alert("hello world"); }

Notice the event as onclick instead of onClick.

JS Bin example.

HashMap does not allow primitive data types as arguments. It can only accept objects so

HashMap<int, myObject> myMap = new HashMap<int, myObject>();

will not work.

You have to change the declaration to

HashMap<Integer, myObject> myMap = new HashMap<Integer, myObject>();

so even when you do the following

myMap.put(2,myObject);

The primitive data type is autoboxed to an Integer object.

8 (int) === boxing ===> 8 (Integer)

You can read more on autoboxing here http://docs.oracle.com/javase/tutorial/java/data/autoboxing.html

Google Chrome now supports this (Developer Tools > Network > [XHR item in list] Preview).

In addition, you can use a third party tool to format the json content. Here's one that presents a tree view, and here's another that merely formats the text (and does validation).

I would recommend to use Bootstrap. http://getbootstrap.com/. This approach is very straight-forward and light weight.

<div class="navbar navbar-inverse navbar-fixed-top">
   <div class="container">
      <div class="navbar-collapse collapse">
         <ul class="nav navbar-nav navbar-fixed-top">
            <li><a href="#home"> <br>BLINK</a></li>
                <li><a href="#news"><br>ADVERTISING WITH BLINK</a></li>
                <li><a href="#contact"><br>EDUCATING WITH BLINK</a></li>
                <li><a href="#about"><br>ABOUT US</a></li>
            </ul>
        </div>
    </div>
</div>

You need to include the Bootstrap into your project, which will include the necessary scripts and styles. Then just call the class 'navbar-fixed-top'. This will do the trick. See above example

just use UPDATE query without condition like this

 UPDATE tablename SET online_status=0;

If you want to setup a third-party filter you can use FilterRegistrationBean. For example the equivalent of web.xml

<filter>
     <filter-name>SomeFilter</filter-name>
        <filter-class>com.somecompany.SomeFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>SomeFilter</filter-name>
    <url-pattern>/url/*</url-pattern>
    <init-param>
       <param-name>paramName</param-name>
       <param-value>paramValue</param-value>
    </init-param>
</filter-mapping>

These will be the two beans in your @Configuration file

@Bean
public FilterRegistrationBean someFilterRegistration() {

    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(someFilter());
    registration.addUrlPatterns("/url/*");
    registration.addInitParameter("paramName", "paramValue");
    registration.setName("someFilter");
    registration.setOrder(1);
    return registration;
} 

public Filter someFilter() {
    return new SomeFilter();
}

The above was tested with spring-boot 1.2.3

You can use tools own browser (Firefox, IE, Chrome...) to debug your JavaScript.

As for resizing, Firefox/Chrome has own resources accessible via Ctrl + Shift + I OR F12. Going tab "style editor" and clicking "adaptive/responsive design" icon.

*Another way is to install an addon like "Web Developer"

Method 1

The problem with your code is that you are selecting the .remode_hover that is a descendant of .remode_selected. So the first part of getting your code to work correctly is by removing that space

.reMode_selected.reMode_hover:hover

Then, in order to get the style to not work, you have to override the style set by the :hover. In other words, you need to counter the background-color property. So the final code will be

.reMode_selected.reMode_hover:hover {
  background-color:inherit;
}
.reMode_hover:hover {
  background-color: #f0ac00;
}

Fiddle

Method 2

An alternative method would be to use :not(), as stated by others. This will return any element that doesn't have the class or property stated inside the parenthesis. In this case, you would put .remode_selected in there. This will target all elements that don't have a class of .remode_selected

Fiddle

However, I would not recommend this method, because of the fact that it was introduced in CSS3, so browser support is not ideal.

Method 3

A third method would be to use jQuery. You can target the .not() selector, which would be similar to using :not() in CSS, but with much better browser support

Fiddle

Combining the best of these answers, if you do:

command 2> >(grep -v something 1>&2)

...then all stdout is preserved as stdout and all stderr is preserved as stderr, but you won't see any lines in stderr containing the string "something".

This has the unique advantage of not reversing or discarding stdout and stderr, nor smushing them together, nor using any temporary files.

Enable Remote Access (Grant) Home / Tutorials / Mysql / Enable Remote Access (Grant) If you try to connect to your mysql server from remote machine, and run into error like below, this article is for you.

ERROR 1130 (HY000): Host ‘1.2.3.4’ is not allowed to connect to this MySQL server

Change mysql config

Start with editing mysql config file

vim /etc/mysql/my.cnf

Comment out following lines.

#bind-address           = 127.0.0.1
#skip-networking

If you do not find skip-networking line, add it and comment out it.

Restart mysql server.

~ /etc/init.d/mysql restart

Change GRANT privilege

You may be surprised to see even after above change you are not getting remote access or getting access but not able to all databases.

By default, mysql username and password you are using is allowed to access mysql-server locally. So need to update privilege.

Run a command like below to access from all machines. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

Run a command like below to give access from specific IP. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

You can replace 1.2.3.4 with your IP. You can run above command many times to GRANT access from multiple IPs.

You can also specify a separate USERNAME & PASSWORD for remote access.

You can check final outcome by:

SELECT * from information_schema.user_privileges where grantee like "'USERNAME'%";

Finally, you may also need to run:

mysql> FLUSH PRIVILEGES;

Test Connection

From terminal/command-line:

mysql -h HOST -u USERNAME -pPASSWORD

If you get a mysql shell, don’t forget to run show databases; to check if you have right privileges from remote machines.

Bonus-Tip: Revoke Access

If you accidentally grant access to a user, then better have revoking option handy.

Following will revoke all options for USERNAME from all machines:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'%';
Following will revoke all options for USERNAME from particular IP:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'1.2.3.4';
Its better to check information_schema.user_privileges table after running REVOKE command.

If you see USAGE privilege after running REVOKE command, its fine. It is as good as no privilege at all. I am not sure if it can be revoked.

You can put an equal formula, then copy it so reference the whole range (one cell goes into one cell)

=Sheet2!A1

If you need to concatenate the results, you'll need a longer formula, or a user-defined function (i.e. macro).

=Sheet2!A1&Sheet2!B1&Sheet2!C1&Sheet2!D1&Sheet2!E1&Sheet2!F1

Oracle's error message should be somewhat longer. It usually looks like this:

ORA-00001: unique constraint (TABLE_UK1) violated

The name in parentheses is the constrait name. It tells you which constraint was violated.

You would need a mapping provider for MySQL. That is an extra thing the Entity Framework needs to make the magic happen. This blog talks about other mapping providers besides the one Microsoft is supplying. I haven't found any mentionings of MySQL.

After struggling with various techniques for a couple of days I have to say that this appears to be impossible. Even using javascript (which I don't want to do) it doesn't seem possible.

To clarify for those who may not have understood - this is what I am looking for: in publishing it is quite common to layout an inset (picture, table, figure, etc.) so that its bottom lines up with the bottom of the last line of text of a block (or page) with text flowing around the inset in a natural manner above and to the right or left depending on which side of the page the inset is on. In html/css it is trivial to use the float style to line up the top of an inset with the top of a block but to my surprise it appears impossible to line up the bottom of the text and inset despite it being a common layout task.

I guess I'll have to revisit the design goals for this item unless anyone has a last minute suggestion.

Checkout Xdebbug's var_dump settings, particularly the values of these settings:

xdebug.var_display_max_children
xdebug.var_display_max_data
xdebug.var_display_max_depth

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

$new_website = substr($str, ($pos = strrpos($str, '//')) !== false ? $pos + 2 : 0); 

This would remove everything before the '//'.

EDIT

This one is tested. Using strrpos() instead or strpos().

In recent versions of python, you can use marshmallow-dataclass:

from marshmallow_dataclass import dataclass

@dataclass
class Payload
    action:str
    method:str
    data:str

Payload.Schema().load({"action":"print","method":"onData","data":"Madan Mohan"})

On any linux system with the NVIDIA driver installed and loaded into the kernel, you can execute:

cat /proc/driver/nvidia/version

to get the version of the currently loaded NVIDIA kernel module, for example:

$ cat /proc/driver/nvidia/version 
NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.54  Sat Sep 29 00:05:49 PDT 2012
GCC version:  gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 

You can append to your PATH in a minimal fashion. No need for parentheses unless you're appending more than one element. It also usually doesn't need quotes. So the simple, short way to append is:

path+=/some/new/bin/dir

This lower-case syntax is using path as an array, yet also affects its upper-case partner equivalent, PATH (to which it is "bound" via typeset).

(Notice that no : is needed/wanted as a separator.)

Common interactive usage

Then the common pattern for testing a new script/executable becomes:

path+=$PWD/.
# or
path+=$PWD/bin

Common config usage

You can sprinkle path settings around your .zshrc (as above) and it will naturally lead to the earlier listed settings taking precedence (though you may occasionally still want to use the "prepend" form path=(/some/new/bin/dir $path)).

Related tidbits

Treating path this way (as an array) also means: no need to do a rehash to get the newly pathed commands to be found.

Also take a look at vared path as a dynamic way to edit path (and other things).

You may only be interested in path for this question, but since we're talking about exports and arrays, note that arrays generally cannot be exported.

You can even prevent PATH from taking on duplicate entries (refer to this and this):

typeset -U path

Use NGX Cookie Service

Inastall this package: npm install ngx-cookie-service --save

Add the cookie service to your app.module.ts as a provider:

import { CookieService } from 'ngx-cookie-service';
@NgModule({
  declarations: [ AppComponent ],
  imports: [ BrowserModule, ... ],
  providers: [ CookieService ],
  bootstrap: [ AppComponent ]
})

Then call in your component:

import { CookieService } from 'ngx-cookie-service';

constructor( private cookieService: CookieService ) { }

ngOnInit(): void {
  this.cookieService.set( 'name', 'Test Cookie' ); // To Set Cookie
  this.cookieValue = this.cookieService.get('name'); // To Get Cookie
}

That's it!

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

If you do so, and you're using fail2ban, you will need to enable the proper filters/actions:

Put the following lines in /etc/fail2ban/jail.d/sshd.local

[ssh-iptables]
enabled  = true
filter   = sshd
action   = iptables[name=SSH, port=ssh, protocol=tcp]
logpath  = /var/log/secure
maxretry = 5
bantime = 86400

Enable and start fail2ban:

systemctl enable fail2ban
systemctl start fail2ban

Reference: http://blog.iopsl.com/fail2ban-on-centos-7-to-protect-ssh-part-ii/

you should give permission on your db

grant execute on (packageName or tableName) to user;

You can also use the shorter format

From the man page:

%F     full date; same as %Y-%m-%d

Example:

#!/bin/bash
date_today=$(date +%F)
date_dir=$(date +%F -d yesterday)

You can use the get(Object key) method from the HashMap. Be aware that i many cases your Key Class should override the equals method, to be a useful class for a Map key.

Here's a simple single threaded sleep based version that drifts, but tries to auto-correct when it detects drift.

NOTE: This will only work if the following 3 reasonable assumptions are met:

1. The time period is much larger than the execution time of the function being executed
2. The function being executed takes approximately the same amount of time on each call
3. The amount of drift between calls is less than a second

-

from datetime import timedelta
from datetime import datetime

def exec_every_n_seconds(n,f):
    first_called=datetime.now()
    f()
    num_calls=1
    drift=timedelta()
    time_period=timedelta(seconds=n)
    while 1:
        time.sleep(n-drift.microseconds/1000000.0)
        current_time = datetime.now()
        f()
        num_calls += 1
        difference = current_time - first_called
        drift = difference - time_period* num_calls
        print "drift=",drift

Since the border is used just for visual appearance, you could put it into the ListBoxItem's ControlTemplate and modify the properties there. In the ItemTemplate, you could place only the StackPanel and the TextBlock. In this way, the code also remains clean, as in the appearance of the control will be controlled via the ControlTemplate and the data to be shown will be controlled via the DataTemplate.

Existing Solution

There could be 3 solution from this posting and other stackoverflow article.

Solution 1

    var lastScrollTop = 0;
    $(window).on('scroll', function() {
        st = $(this).scrollTop();
        if(st < lastScrollTop) {
            console.log('up 1');
        }
        else {
            console.log('down 1');
        }
        lastScrollTop = st;
    });

Solution 2

    $('body').on('DOMMouseScroll', function(e){
        if(e.originalEvent.detail < 0) {
            console.log('up 2');
        }
        else {
            console.log('down 2');
        }
    });

Solution 3

    $('body').on('mousewheel', function(e){
        if(e.originalEvent.wheelDelta > 0) {
            console.log('up 3');
        }

Combined Solution

I checked that side effect from IE 11 and IE 8 is come from if else statement. So, I replaced it with if else if statement as following.

From the multi browser test, I decided to use Solution 3 for common browsers and Solution 1 for firefox and IE 11.

I referred this answer to detect IE 11.

    // Detect IE version
    var iev=0;
    var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
    var trident = !!navigator.userAgent.match(/Trident\/7.0/);
    var rv=navigator.userAgent.indexOf("rv:11.0");

    if (ieold) iev=new Number(RegExp.$1);
    if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
    if (trident&&rv!=-1) iev=11;

    // Firefox or IE 11
    if(typeof InstallTrigger !== 'undefined' || iev == 11) {
        var lastScrollTop = 0;
        $(window).on('scroll', function() {
            st = $(this).scrollTop();
            if(st < lastScrollTop) {
                console.log('Up');
            }
            else if(st > lastScrollTop) {
                console.log('Down');
            }
            lastScrollTop = st;
        });
    }
    // Other browsers
    else {
        $('body').on('mousewheel', function(e){
            if(e.originalEvent.wheelDelta > 0) {
                console.log('Up');
            }
            else if(e.originalEvent.wheelDelta < 0) {
                console.log('Down');
            }
        });
    }

In my case, the problem was solved after I've deleted all the remove reference files under the directory .git.

If you look at the message, it would tell you which files you need to delete (specifically).

The files to delete sit under .git/refs/remotes.

I've just deleted all the files there, and ran gc prune

git gc --prune=now

After that, everything works just fine.

Just set the position of the div and you may have to set the z-index.

ex.

div#map-div {
    position: absolute;
    left: 10px;
    top: 10px;
}
div#cover-div {
    position:absolute;
    left:10px;
    top: 10px;
    z-index:3;
}

If you want all the paths, use recursion.

Using an adjacency list, preferably, create a function f() that attempts to fill in a current list of visited vertices. Like so:

void allPaths(vector<int> previous, int current, int destination)
{
    previous.push_back(current);

    if (current == destination)
        //output all elements of previous, and return

    for (int i = 0; i < neighbors[current].size(); i++)
        allPaths(previous, neighbors[current][i], destination);
}

int main()
{
    //...input
    allPaths(vector<int>(), start, end);
}

Due to the fact that the vector is passed by value (and thus any changes made further down in the recursive procedure aren't permanent), all possible combinations are enumerated.

You can gain a bit of efficiency by passing the previous vector by reference (and thus not needing to copy the vector over and over again) but you'll have to make sure that things get popped_back() manually.

One more thing: if the graph has cycles, this won't work. (I assume in this case you'll want to find all simple paths, then) Before adding something into the previous vector, first check if it's already in there.

If you want all shortest paths, use Konrad's suggestion with this algorithm.

Yet another way: if you are working with a C string, e.g. const char *, C native atoi() is more convenient.

If you're using NuGet it is worth going to 'Manage NuGet Packages For Solution', finding the package which is causing issues and hitting update. It should then bring all of the packages up to the latest version and resolve the problem.

Worth a shot as it's a quick and easy.

Mark Russinovich wrote a terrific tool called AccessChk that lets you get this information from the command line. No installation is necessary.

http://technet.microsoft.com/en-us/sysinternals/bb664922.aspx

For example:

accesschk.exe /accepteula -q -a SeServiceLogonRight

Returns this for me:

IIS APPPOOL\DefaultAppPool
IIS APPPOOL\Classic .NET AppPool
NT SERVICE\ALL SERVICES

By contrast, whoami /priv and whoami /all were missing some entries for me, like SeServiceLogonRight.

It may not be possible in all situations, but why not simply use the value of a different random TextView that exists in the same Activity and that carries the colour you are looking for?

txtOk.setTextColor(txtSomeOtherText.getCurrentTextColor());

For raw speed, use C. For power, use C++. For .NET compatibility, use C#.

They're all pretty complex as languages go; C through decades of gradual accretion, C++ through years of more rapid enhancement, and C# through the power of Microsoft.

The most simple way is to use Record type Record<number, productDetails >

interface productDetails {
   productId : number , 
   price : number , 
   discount : number
};

const myVar : Record<number, productDetails> = {
   1: {
       productId : number , 
       price : number , 
       discount : number
   }
}

Please try this one

NSError *error;
NSDictionary *responseJson = [NSJSONSerialization JSONObjectWithData:webData
                                options:NSJSONReadingMutableContainers
                                error:&error];

select * into mytable_backup from mytable

Makes a copy of table mytable, and every row in it, called mytable_backup.

It's an ordinary Python list. The exception that you would catch for this is IndexError, but you're better off just checking the length instead.

if len(sys.argv) >= 2:
  startingpoint = sys.argv[1]
else:
  startingpoint = 'blah'

In case anyone else looking for additional "enter" keypress support, here's an update to the fiddle provided by Gloppy

Code for keypress binding:

elm.bind("keydown keypress", function(event) {
    if (event.which === 13) {
        scope.$apply(function() {
            ngModelCtrl.$setViewValue(elm.val());
        });
    }
});

imagecopyresampled() will take a rectangular area from $src_image of width $src_w and height $src_h at position ($src_x, $src_y) and place it in a rectangular area of $dst_image of width $dst_w and height $dst_h at position ($dst_x, $dst_y).

If the source and destination coordinates and width and heights differ, appropriate stretching or shrinking of the image fragment will be performed. The coordinates refer to the upper left corner.

This function can be used to copy regions within the same image. But if the regions overlap, the results will be unpredictable.

- Edit -

If $src_w and $src_h are smaller than $dst_w and $dst_h respectively, thumb image will be zoomed in. Otherwise it will be zoomed out.

<?php
$dst_x = 0;   // X-coordinate of destination point
$dst_y = 0;   // Y-coordinate of destination point
$src_x = 100; // Crop Start X position in original image
$src_y = 100; // Crop Srart Y position in original image
$dst_w = 160; // Thumb width
$dst_h = 120; // Thumb height
$src_w = 260; // Crop end X position in original image
$src_h = 220; // Crop end Y position in original image

// Creating an image with true colors having thumb dimensions (to merge with the original image)
$dst_image = imagecreatetruecolor($dst_w, $dst_h);
// Get original image
$src_image = imagecreatefromjpeg('images/source.jpg');
// Cropping
imagecopyresampled($dst_image, $src_image, $dst_x, $dst_y, $src_x, $src_y, $dst_w, $dst_h, $src_w, $src_h);
// Saving
imagejpeg($dst_image, 'images/crop.jpg');
?>

I also had issue with git PS1 slowness, although for a long time I was thinking it's a database size problem (big repository) and was trying various git gc tricks, and were looking for other reasons, just like you. However, in my case, the problem was this line:

function ps1_gitify
{
   status=$(git status 2>/dev/null )      # <--------------------
   if [[ $status =~ "fatal: Not a git repository" ]]
   then
       echo ""
   else
       echo "$(ps1_git_branch_name)  $(ps1_git_get_sha)"
  fi
}

Doing the git status for every command line status line was slow. Ouch. It was something I wrote by hand. I saw that was a problem when I tried the

export PS1='$'

like mentioned in one answer here. The command line was lightning fast.

Now I'm using this:

function we_are_in_git_work_tree
{
    git rev-parse --is-inside-work-tree &> /dev/null
}

function ps1_gitify
{
    if ! we_are_in_git_work_tree
    then
    ...

From the Stack Overflow post PS1 line with git current branch and colors and it works fine. Again have a fast Git command line.

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

   <% String s="Hi"; %>
   var v ="<%=s%>"; 

I know it's old question but it still in first 10 links in google.

It is not very efficient to save rows one-by-one because it cause database call in the loop and you better avoid that, especially when you need to insert huge portions of data.

It's better (and significantly faster) to use batch insert.

INSERT INTO `mouldings` (suppliers_code, name, cost)
VALUES
    ('s1', 'supplier1', 1.111), 
    ('s2', 'supplier2', '2.222')

You can build such a query manually and than do Model.connection.execute(RAW SQL STRING) (not recomended) or use gem activerecord-import (it was first released on 11 Aug 2010) in this case just put data in array rows and call Model.import rows

refer to gem docs for details

Or, if for some reason you don't like any of the more sensible answers, just discard everything to the right of (and including) the space.

Swift 4:

// add 5 minutes to date

let date = startDate.addingTimeInterval(TimeInterval(5.0 * 60.0))

// subtract 5 minutes from date

let date = startDate.addingTimeInterval(TimeInterval(-5.0 * 60.0))

Swift 5.1:

// subtract 5 minutes from date
transportationFromDate.addTimeInterval(TimeInterval(-5.0 * 60.0))

Inside of your loop, you have the key, which you can use to retrieve the value from the Map:

for (String key: mss1.keySet()) {
    System.out.println(key + ": " + mss1.get(key));
}

You don't see anything, because of buffering. The output is shown, when there are enough lines or end of file is reached. tail -f means wait for more input, but there are no more lines in file and so the pipe to grep is never closed.

If you omit -f from tail the output is shown immediately:

tail file | grep A1 | awk '{print $NF}'

@EdMorton is right of course. Awk can search for A1 as well, which shortens the command line to

tail file | awk '/A1/ {print $NF}'

or without tail, showing the last column of all lines containing A1

awk '/A1/ {print $NF}' file

Thanks to @MitchellTracy's comment, tail might miss the record containing A1 and thus you get no output at all. This may be solved by switching tail and awk, searching first through the file and only then show the last line:

awk '/A1/ {print $NF}' file | tail -n1

You need to add JQuery js before adding bootstrap js file, because BootStrap use jqueries function. So make sure to load first jquery js and then bootstap js file.

<!-- JQuery Core JavaScript -->
<script src="app/js/jquery.min.js"></script>

<!-- Bootstrap Core JavaScript -->
<script src="app/js/bootstrap.min.js"></script>

Check out the basics of regular expressions in a tutorial. All it requires is two anchors and a repeated character class:

^[a-zA-Z ._-]*$

If you use the case-insensitive modifier, you can shorten this to

^[a-z ._-]*$

Note that the space is significant (it is just a character like any other).

I would recommend that you have a look at SUDS

"Suds is a lightweight SOAP python client for consuming Web Services."

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

At the Method Level

1.When the annotation is used at the method level it indicates the purpose of that method is to add one or more model attributes

@ModelAttribute
public void addAttributes(Model model) {
model.addAttribute("india", "india");
}

At the Method Argument 1. When used as a method argument, it indicates the argument should be retrieved from the model. When not present and should be first instantiated and then added to the model and once present in the model, the arguments fields should be populated from all request parameters that have matching names So, it binds the form data with a bean.

 @RequestMapping(value = "/addEmployee", method = RequestMethod.POST)
  public String submit(@ModelAttribute("employee") Employee employee) {
  return "employeeView";
  }

Assumes, you have a data.json file in the src/app folder of your project with the following values:

[
    {
        "id": 1,
        "name": "Licensed Frozen Hat",
        "description": "Incidunt et magni est ut.",
        "price": "170.00",
        "imageUrl": "https://source.unsplash.com/1600x900/?product",
        "quantity": 56840
    },
    ...
]

3 Methods for Reading Local JSON Files

Method 1: Reading Local JSON Files Using TypeScript 2.9+ import Statement

import { Component, OnInit } from '@angular/core';
import * as data from './data.json';

@Component({
  selector: 'app-root',
  template: `<ul>
      <li *ngFor="let product of products">

      </li>
  </ul>`,
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'Angular Example';

  products: any = (data as any).default;

  constructor(){}
  ngOnInit(){
    console.log(data);
  }
}

Method 2: Reading Local JSON Files Using Angular HttpClient

import { Component, OnInit } from '@angular/core';
import { HttpClient } from "@angular/common/http";


@Component({
  selector: 'app-root',
  template: `<ul>
      <li *ngFor="let product of products">

      </li>
  </ul>`,
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'Angular Example';
  products: any = [];

  constructor(private httpClient: HttpClient){}
  ngOnInit(){
    this.httpClient.get("assets/data.json").subscribe(data =>{
      console.log(data);
      this.products = data;
    })
  }
}

Method 3: Reading Local JSON Files in Offline Angular Apps Using ES6+ import Statement

But first we need to add a typing file as follows:

declare module "*.json" {
  const value: any;
  export default value;
}

Add this inside a new file json-typings.d.ts file in the src/app folder.

Now, you can import JSON files just like TypeScript 2.9+.

import * as data from "data.json";

If you want insert all data from one table to another table there is a very simply sql

INSERT INTO destinationTable  (SELECT * FROM sourceDbName.SourceTableName);

You can use java.security.MessageDigest with SHA as your algorithm choice.

For reference,

Try available example here

Archive process (using Xcode 8.3.2)

Note : If you are using creating IPA using drag-and-drop process using iTunes Mac app then this is no longer applicable for iTunes 12.7 since there is no built-in App store in iTunes 12.7.

1. Select ‘Generic iOS Device’ on device list in Xcode

2. Clean the project (cmd + shift + k as shortcut)

3. Go to Product -> Archive your project

4. Once archive is succeeded this will open a window with archived project

5. You can validate your archive by pressing Validate (optional step but recommended)

6. Now press on Export button

7. This will open list of method for export. Select the export method as per your requirement and click on Next button.

8. This will show list of team for provisioning. Select accordingly and press on ‘Choose’ button.

9. Now you’ve to select Device support -> Export one app for all compatible devices (recommended). If you want IPA for specific device then select the device variant from list and press on ‘Next’ button.

10. Now you’ll be able to see the ‘Summary’ and then press on ‘Next’ button

11. Thereafter IPA file generation beings and later you’ll be able to export the IPA as [App Name - Date Time] and then press on ‘Done’.

Thats how it works stored procedures run in order, you don't need begin just something like

exec dbo.sp1
exec dbo.sp2

You can reverse your list by list.reverse() and finaly call RecylerView.scrollToPosition(0)

    list.reverse()
    layout = LinearLayoutManager(this,LinearLayoutManager.VERTICAL,true)  
    RecylerView.scrollToPosition(0)

Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.

You'll need to unpack the file or use it directly.

If you have a Context, you can use context.getAssets().open("myfoldername/myfilename"); to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File).

Single layer

To initialize the weights of a single layer, use a function from torch.nn.init. For instance:

conv1 = torch.nn.Conv2d(...)
torch.nn.init.xavier_uniform(conv1.weight)

Alternatively, you can modify the parameters by writing to conv1.weight.data (which is a torch.Tensor). Example:

conv1.weight.data.fill_(0.01)

The same applies for biases:

conv1.bias.data.fill_(0.01)

nn.Sequential or custom nn.Module

Pass an initialization function to torch.nn.Module.apply. It will initialize the weights in the entire nn.Module recursively.

apply(fn): Applies fn recursively to every submodule (as returned by .children()) as well as self. Typical use includes initializing the parameters of a model (see also torch-nn-init).

Example:

def init_weights(m):
    if type(m) == nn.Linear:
        torch.nn.init.xavier_uniform(m.weight)
        m.bias.data.fill_(0.01)

net = nn.Sequential(nn.Linear(2, 2), nn.Linear(2, 2))
net.apply(init_weights)
