First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

The code for the confirmation dialogue can be written shorter this way:

$scope.$on('$locationChangeStart', function( event ) {
    var answer = confirm("Are you sure you want to leave this page?")
    if (!answer) {
        event.preventDefault();
    }
});

This SQL query gives output similar to \dx:

SELECT e.extname AS "Name", e.extversion AS "Version", n.nspname AS "Schema", c.description AS "Description" 
FROM pg_catalog.pg_extension e 
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = e.extnamespace 
LEFT JOIN pg_catalog.pg_description c ON c.objoid = e.oid AND c.classoid = 'pg_catalog.pg_extension'::pg_catalog.regclass 
ORDER BY 1;

Apparently, your project is targeting Windows Phone 7.0. Unfortunately the constructors that accept IEnumerable<T> or List<T> are not available in WP 7.0, only the parameterless constructor. The other constructors are available in Silverlight 4 and above and WP 7.1 and above, just not in WP 7.0.

I guess your only option is to take your list and add the items into a new instance of an ObservableCollection individually as there are no readily available methods to add them in bulk. Though that's not to stop you from putting this into an extension or static method yourself.

var list = new List<SomeType> { /* ... */ };
var oc = new ObservableCollection<SomeType>();
foreach (var item in list)
    oc.Add(item);

But don't do this if you don't have to, if you're targeting framework that provides the overloads, then use them.

This is what has to occur.

You have to copy your DLL that you want to Register to: c:\windows\SysWOW64\

Then in the Run dialog, type this in: C:\Windows\SysWOW64\regsvr32.exe c:\windows\system32\YourDLL.dll

and you will get the message:

DllRegisterServer in c:\windows\system32\YourDLL.dll succeeded.

You can add the attribute readonly to the input:

<input type="text" value="3"
       class="field left" readonly="readonly">

These steps will do it:

git reset --hard HEAD
git clean -f -x -d -n

then without -n

This will take care of all local changes. Now the commits...

git status

and note the line such as:

Your branch is ahead of 'xxxx' by N commits.

Take a note of number 'N' now:

git reset --hard HEAD~N
git pull

and finally:

git status

should show nothing to add/commit. All clean.

However, a fresh clone can do the same (but is much slow).

===Updated===

As my git knowledge slightly improved over the the time, I have come up with yet another simpler way to do the same. Here is how (#with explanation). While in your working branch:

git fetch # This updates 'remote' portion of local repo. 
git reset --hard origin/<your-working-branch>
# this will sync your local copy with remote content, discarding any committed
# or uncommitted changes.

Although your local commits and changes will disappear from sight after this, it is possible to recover committed changes, if necessary.

DateTime.remove({}, callback) The empty object will match all of them.

I have stumbled across the same problem and this was the best solution I could get:

/*Adding the event listener (the 'mousemove' event, in this specific case)*/
element.onmousemove = function(event) {
    /*do your stuff*/
};
/*Removing the event listener*/
element.onmousemove = null;

Please keep in mind I have only tested this for the window element and for the 'mousemove' event, so there could be some problems with this approach.

I did't want to change my source code to add additional observer , so I have written following simple example:

//EVENT DRIVEN OBSERVER PATTERN
public class Publisher
{
    public Publisher()
    {
        var observable = new Observable();
        observable.PublishData("Hello World!");
    }
}

//Server will send data to this class's PublishData method
public class Observable
{
    public event Receive OnReceive;

    public void PublishData(string data)
    {
        //Add all the observer below
        //1st observer
        IObserver iObserver = new Observer1();
        this.OnReceive += iObserver.ReceiveData;
        //2nd observer
        IObserver iObserver2 = new Observer2();
        this.OnReceive += iObserver2.ReceiveData;

        //publish data 
        var handler = OnReceive;
        if (handler != null)
        {
            handler(data);
        }
    }
}

public interface IObserver
{
    void ReceiveData(string data);
}

//Observer example
public class Observer1 : IObserver
{
    public void ReceiveData(string data)
    {
        //sample observers does nothing with data :)
    }
}

public class Observer2 : IObserver
{
    public void ReceiveData(string data)
    {
        //sample observers does nothing with data :)
    }
}

Here is a polyglot program for BASH and Windows CMD that runs a series of commands and quits out if any of them fail:

#!/bin/bash 2> nul

:; set -o errexit
:; function goto() { return $?; }

command 1 || goto :error

command 2 || goto :error

command 3 || goto :error

:; exit 0
exit /b 0

:error
exit /b %errorlevel%

I have used this type of thing in the past for a multiple platform continuous integration script.

There are many ways you can find the difference between dates & times. One of the simplest ways that I know of would be:

      Calendar calendar1 = Calendar.getInstance();
      Calendar calendar2 = Calendar.getInstance();
      calendar1.set(2012, 04, 02);
      calendar2.set(2012, 04, 04);
      long milsecs1= calendar1.getTimeInMillis();
      long milsecs2 = calendar2.getTimeInMillis();
      long diff = milsecs2 - milsecs1;
      long dsecs = diff / 1000;
      long dminutes = diff / (60 * 1000);
      long dhours = diff / (60 * 60 * 1000);
      long ddays = diff / (24 * 60 * 60 * 1000);

      System.out.println("Your Day Difference="+ddays);

The print statement is just an example - you can format it, the way you like.

You can use in to look for an item in a collection, and a list comprehension to extract the field you are interested in. This (works for lists, sets, tuples, and anything that defines __contains__ or __getitem__).

if 5 in [data.n for data in myList]:
    print "Found it"

For PHP's own session cookies on Apache:
add this to your Apache configuration or .htaccess

<IfModule php5_module>
    php_flag session.cookie_httponly on
</IfModule>

This can also be set within a script, as long as it is called before session_start().

ini_set( 'session.cookie_httponly', 1 );

$('#foo option:selected').data('id');

componentWillReceiveProps is being deprecated because using it "often leads to bugs and inconsistencies".

If something changes from the outside, consider resetting the child component entirely with key.

Providing a key prop to the child component makes sure that whenever the value of key changes from the outside, this component is re-rendered. E.g.,

<EmailInput
  defaultEmail={this.props.user.email}
  key={this.props.user.id}
/>

On its performance:

While this may sound slow, the performance difference is usually insignificant. Using a key can even be faster if the components have heavy logic that runs on updates since diffing gets bypassed for that subtree.

If s is your string:

s.replace(/^[^(]*\(/, "") // trim everything before first parenthesis
 .replace(/\)[^(]*$/, "") // trim everything after last parenthesis
 .split(/\)[^(]*\(/);      // split between parenthesis

if i want to check if any speicfic position of command line arguement is passed or not then how to check? like for example in some scenarios 2 command line args will be passed and in some only one will be passed then how do it check wheather the specfic commnad line is passed or not?

public class check {

public static void main(String[] args) {
if(args[0].length()!=0)
{
System.out.println("entered first if");
}
if(args[0].length()!=0 && args[1].length()!=0)
{
System.out.println("entered second if");
}
}
}

So in the above code if args[1] is not passed then i get java.lang.ArrayIndexOutOfBoundsException:

so how do i tackle this where i can check if second arguement is passed or not and if passed then enter it. need assistance asap.

Here's another solution, usable if the frames are from different domains.

var frame = /*the iframe DOM object*/;
frame.contentWindow.postMessage({call:'sendValue', value: /*value*/}, /*frame domain url or '*'*/);

And in the frame itself:

window.addEventListener('message', function(event) {
    var origin = event.origin || event.originalEvent.origin; // For Chrome, the origin property is in the event.originalEvent object.
    if (origin !== /*the container's domain url*/)
        return;
    if (typeof event.data == 'object' && event.data.call=='sendValue') {
        // Do something with event.data.value;
    }
}, false);

Don't know which browsers support this, though.

There is an easy fix for this one:

When you want to disable the viewpager scrolling then:

mViewPager.setOnTouchListener(new OnTouchListener() {

   public boolean onTouch(View arg0, MotionEvent arg1) {
      return true;
   }
}); 

And when you want to re-enable it then:

mViewPager.setOnTouchListener(null);

That will do the trick.

The Functional Approach

All the cool kids are doing functional programming (hello React users) these days so I thought I would give the functional solution. In my view it's actually a lot nicer than the imperatival for and each loops that have been proposed thus far and with ES6 syntax it is quite elegant.

Update

There's now a great way of doing this called findIndex which takes a function that return true/false based on whether the array element matches (as always, check for browser compatibility though).

var index = peoples.findIndex(function(person) {
  return person.attr1 == "john"
}

With ES6 syntax you get to write this:

var index = peoples.findIndex(p => p.attr1 == "john")

The (Old) Functional Approach

TL;DR

If you're looking for index where peoples[index].attr1 == "john" use:

var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");

Explanation

Step 1

Use .map() to get an array of values given a particular key:

var values = object_array.map(function(o) { return o.your_key; });

The line above takes you from here:

var peoples = [
  { "attr1": "bob", "attr2": "pizza" },
  { "attr1": "john", "attr2": "sushi" },
  { "attr1": "larry", "attr2": "hummus" }
];

To here:

var values = [ "bob", "john", "larry" ];

Step 2

Now we just use .indexOf() to find the index of the key we want (which is, of course, also the index of the object we're looking for):

var index = values.indexOf(your_value);

Solution

We combine all of the above:

var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");

Or, if you prefer ES6 syntax:

var index = peoples.map((o) => o.attr1).indexOf("john");

Demo:

var peoples = [_x000D_
  { "attr1": "bob", "attr2": "pizza" },_x000D_
  { "attr1": "john", "attr2": "sushi" },_x000D_
  { "attr1": "larry", "attr2": "hummus" }_x000D_
];_x000D_
_x000D_
var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");_x000D_
console.log("index of 'john': " + index);_x000D_
_x000D_
var index = peoples.map((o) => o.attr1).indexOf("larry");_x000D_
console.log("index of 'larry': " + index);_x000D_
_x000D_
var index = peoples.map(function(o) { return o.attr1; }).indexOf("fred");_x000D_
console.log("index of 'fred': " + index);_x000D_
_x000D_
var index = peoples.map((o) => o.attr2).indexOf("pizza");_x000D_
console.log("index of 'pizza' in 'attr2': " + index);

var min = dt.AsEnumerable().Min(row => row["AccountLevel"]);
var max = dt.AsEnumerable().Max(row => row["AccountLevel"]);

Assuming you have a JSON hash hanging around somewhere, to automatically convert it into something like WarHog's version, wrap your JSON hash contents in %q{hsh} tags.

This seems to automatically add all the necessary escaped text like in WarHog's answer.

You could try setting up a filter using the unicodedata.category() function:

import unicodedata
printable = {'Lu', 'Ll'}
def filter_non_printable(str):
  return ''.join(c for c in str if unicodedata.category(c) in printable)

See Table 4-9 on page 175 in the Unicode database character properties for the available categories

Use

Path.GetTempFileName()

or use new GUID().

Path.GetTempFilename() on MSDN.

async Task<int> LongTask1() { 
  ...
  return 0; 
}

async Task<int> LongTask2() { 
  ...
  return 1; 
}

...
{
   Task<int> t1 = LongTask1();
   Task<int> t2 = LongTask2();
   await Task.WhenAll(t1,t2);
   //now we have t1.Result and t2.Result
}

this works for me, so try it :

Microsoft.Office.Interop.Excel.Range rng =(Microsoft.Office.Interop.Excel.Range)XcelApp.Cells[1, i];
rng.Font.Bold = true; 
rng.Interior.Color =System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Yellow);
rng.BorderAround(); 

It seems like this is now possible in newer versions (Vue Router 3.0.1):

<router-link :to="{ name: 'fooRoute'}" target="_blank">
  Link Text
</router-link>

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

I had to use the **/* syntax to exclude the files in a folder:

    "linterOptions": {
        "exclude": [
          "src/auto-generated/**/*",
          "src/app/auto-generated/**/*"
        ]
    },

CHAR is a fixed-length data type that uses as much space as possible. So a:= a||'one '; will require more space than is available. Your problem can be reduced to the following example:

declare
  v_foo char(50);
begin
  v_foo := 'A';
  dbms_output.put_line('length of v_foo(A) = ' || length(v_foo));
  -- next line will raise:
  -- ORA-06502: PL/SQL: numeric or value error: character string buffer too small
  v_foo := v_foo || 'B';
  dbms_output.put_line('length of v_foo(AB) = ' || length(v_foo));  
end;
/

Never use char. For rationale check the following question (read also the links):

• Oracle datatype: Should I use VARCHAR2 or CHAR

You need to use the CSS3 transform property rotate - see here for which browsers support it and the prefix you need to use.

One example for webkit browsers is -webkit-transform: rotate(-90deg);

Edit: The question was changed substantially so I have added a demo that works in Chrome/Safari (as I only included the -webkit- CSS prefixed rules). The problem you have is that you do not want to rotate the title div, but simply the text inside it. If you remove your rotation, the <div>s are in the correct position and all you need to do is wrap the text in an element and rotate that instead.

There already exists a more customisable widget as part of the jQuery UI - see the accordion demo page. I am sure with some CSS cleverness you should be able to make the accordion vertical and also rotate the title text :-)

Edit 2: I had anticipated the text center problem and have already updated my demo. There is a height/width constraint though, so longer text could still break the layout.

Edit 3: It looks like the horizontal version was part of the original plan but I cannot see any way of configuring it on the demo page. I was incorrect… the new accordion is part of the upcoming jQuery UI 1.9! So you could try the development builds if you want the new functionality.

Hope this helps!

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.

You can get the Java EE Edition of eclipse with has it pre-installed.

To create and run your first servlet:

1. New... Project... Dynamic Web Project.
2. Right click the project... New Servlet.
3. Write some code in the doGet() method.
4. Find the servers view in the Java EE perspective, it's usually one of the tabs at the bottom.
5. Right click in there and select new Server.
6. Select Tomcat X.X and a wizard will point you to finding the installation.
7. Right click the server you just created and select Add and Remove... and add your created web project.
8. Right click your servlet and select Run > Run on Server...

That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.

There's no such thing as an empty date per se, do you mean something like:

DateTime? myDateTime = null;

There are more than a few people who don't like break and continue. The latest complaint I saw about them was in JavaScript: The Good Parts by Douglas Crockford. But I find that sometimes using one of them really simplifies things, especially if your language doesn't include a do-while or do-until style of loop.

I tend to use break in loops that are searching a list for something. Once found, there's no point in continuing, so you might as well quit.

I use continue when doing something with most elements of a list, but still want to skip over a few.

The break statement also comes in handy when polling for a valid response from somebody or something. Instead of:

Ask a question
While the answer is invalid:
    Ask the question

You could eliminate some duplication and use:

While True:
    Ask a question
    If the answer is valid:
        break

The do-until loop that I mentioned before is the more elegant solution for that particular problem:

Do:
    Ask a question
    Until the answer is valid

No duplication, and no break needed either.

Recently I had the need to perform some encryption/decryption interoperability between javascript and python.

Specifically...

1) Using AES to encrypt in javascript and decrypt in python (Google App Engine) 2) Using RSA to encrypt in javascript and decrypt in python (Google App Engine) 3) Using pycrypto

I found lots and lots of different versions of RSA and AES floating around the web and they were all different in their approach but I did not find a good example of end to end javascript and python interoperability.

Eventually I managed to cobble together something that suited my needs after a lot of trial and error.

Anyhow I knocked up an example of a js/webapp talking to a google app engine hosted python server that uses AES and public key and private key RSA stuff.

I though I'd include it here by link in case it will be of some use to others who need to accomplish the same thing.

http://www.ipowow.com/files/aesrsademo.tar.gz

and see demo at rsa-aes-demo DOT appspot DOT com

Post uses the message body to send the information back to the server, as opposed to Get, which uses the query string (everything after the question mark). It is possible to send both a Get query string and a Post message body in the same request, but that can get a bit confusing so is best avoided.

Generally, best practice dictates that you use Get when you want to retrieve data, and Post when you want to alter it. (These rules aren't set in stone, the specs don't forbid altering data with Get, but it's generally avoided on the grounds that you don't want people making changes just by clicking a link or typing a URL)

Conversely, you can use Post to retrieve data without changing it, but using Get means you can bookmark the page, or share the URL with other people, things you couldn't do if you'd used Post.

• http://en.wikipedia.org/wiki/GET_%28HTTP%29
• http://en.wikipedia.org/wiki/POST_%28HTTP%29

As for the actual format of the data sent in the message body, that's entirely up to the sender and is specified with the Content-Type header. If not specified, the default content-type for HTML forms is application/x-www-form-urlencoded, which means the server will expect the post body to be a string encoded in a similar manner to a GET query string. However this can't be depended on in all cases. RFC2616 says the following on the Content-Type header:

Any HTTP/1.1 message containing an entity-body SHOULD include a
Content-Type header field defining the media type of that body. If
and only if the media type is not given by a Content-Type field, the
recipient MAY attempt to guess the media type via inspection of its
content and/or the name extension(s) of the URI used to identify the
resource. If the media type remains unknown, the recipient SHOULD
treat it as type "application/octet-stream".

Just to clarify the Training/Validation/Test data sets: The training set is used to perform the initial training of the model, initializing the weights of the neural network.

The validation set is used after the neural network has been trained. It is used for tuning the network's hyperparameters, and comparing how changes to them affect the predictive accuracy of the model. Whereas the training set can be thought of as being used to build the neural network's gate weights, the validation set allows fine tuning of the parameters or architecture of the neural network model. It's useful as it allows repeatable comparison of these different parameters/architectures against the same data and networks weights, to observe how parameter/architecture changes affect the predictive power of the network.

Then the test set is used only to test the predictive accuracy of the trained neural network on previously unseen data, after training and parameter/architecture selection with the training and validation data sets.

It's basically the same mechanism as for a non query command with:

• command.CommandText = the name of the stored procedure
• command.CommandType = CommandType.StoredProcedure
• As many calls to command.Parameters.Add as the number of parameters the sp requires
• command.ExecuteNonQuery

There are plenty of examples out there, the first one returned by Google is this one

There's also a little trap you might fall into, if your SP is a function, your return value parameter must be first in the parameters collection

You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-

last_list.append(p.last)

if you assign this to a variable "last_list" again, it will no more be a list (will become a none type variable since you haven't declared the type for that) and append will become invalid in the next run.

If searching for an element is important, I'd recommend std::set instead of std::vector. Using this:

std::find(vec.begin(), vec.end(), x) runs in O(n) time, but std::set has its own find() member (ie. myset.find(x)) which runs in O(log n) time - that's much more efficient with large numbers of elements

std::set also guarantees all the added elements are unique, which saves you from having to do anything like if not contained then push_back()....

I would recommend this to anyone looking for missing functionality:

http://code.google.com/p/ddr-ecma5/

It brings in most of the missing ecma5 functionality to older browers :)

Check your file: settings.gradle for presence lines with included subprojects (for example: include chapter1-bookstore )

There would be multiple ways to find an element (in your case the third Google Search result).

One of the ways would be using Xpath

#For the 3rd Link
driver.findElement(By.xpath(".//*[@id='rso']/li[3]/div/h3/a")).click();
#For the 1st Link
driver.findElement(By.xpath(".//*[@id='rso']/li[2]/div/h3/a")).click();
#For the 2nd Link
driver.findElement(By.xpath(".//*[@id='rso']/li[1]/div/h3/a")).click();

The other options are

By.ByClassName 
By.ByCssSelector 
By.ById
By.ByLinkText
By.ByName
By.ByPartialLinkText 
By.ByTagName 

To better understand each one of them, you should try learning Selenium on something simpler than the Google Search Result page.

Example - http://www.google.com/intl/gu/contact/

To Interact with the Text input field with the placeholder "How can we help? Ask here." You could do it this way -

# By.ByClassName 
driver.findElement(By.ClassName("searchbox")).sendKeys("Hey!");
# By.ByCssSelector 
driver.findElement(By.CssSelector(".searchbox")).sendKeys("Hey!");
# By.ById
driver.findElement(By.Id("query")).sendKeys("Hey!");
# By.ByName
driver.findElement(By.Name("query")).sendKeys("Hey!");
# By.ByXpath
driver.findElement(By.xpath(".//*[@id='query']")).sendKeys("Hey!");

well you can do this:

$(function(){

    var $header = $('#header');
    var $footer = $('#footer');
    var $content = $('#content');
    var $window = $(window).on('resize', function(){
       var height = $(this).height() - $header.height() + $footer.height();
       $content.height(height);
    }).trigger('resize'); //on page load

});

see fiddle here: http://jsfiddle.net/maniator/JVKbR/
demo: http://jsfiddle.net/maniator/JVKbR/show/

To get the format you want:

SELECT (substring(CONVERT(VARCHAR,GETDATE(),22),10,8) + ' ' + SUBSTRING(CONVERT(VARCHAR,getdate(),22), 19,2))

Why are you pulling this from sql?

Initially starting with a pyspark dataframes - I got type conversion errors (when converting to pandas df's and then appending to csv) given the schema/column types in my pyspark dataframes

Solved the problem by forcing all columns in each df to be of type string and then appending this to csv as follows:

with open('testAppend.csv', 'a') as f:
    df2.toPandas().astype(str).to_csv(f, header=False)

A more powerful way of sorting a list of NSString to use things like NSNumericSearch :

NSArray *sortedArrayOfString = [arrayOfString sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
            return [(NSString *)obj1 compare:(NSString *)obj2 options:NSNumericSearch];
        }];

Combined with SortDescriptor, that would give something like :

NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) {
        return [(NSString *)obj1 compare:(NSString *)obj2 options:NSNumericSearch];
    }];
NSArray *sortedArray = [anArray sortedArrayUsingDescriptors:[NSArray arrayWithObject:sort]];

This category worked for me (ios 7, 8 and 9)

H file

@interface UIViewController (navigation)
- (void) presentTransparentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion;
@end

M file

@implementation UIViewController (navigation)
- (void)presentTransparentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion
{
    if(SYSTEM_VERSION_LESS_THAN(@"8.0")) {
        [self presentIOS7TransparentController:viewControllerToPresent withCompletion:completion];

    }else{
        viewControllerToPresent.modalPresentationStyle = UIModalPresentationOverCurrentContext;
         [self presentViewController:viewControllerToPresent animated:YES completion:completion];
    }
}
-(void)presentIOS7TransparentController:(UIViewController *)viewControllerToPresent withCompletion:(void(^)(void))completion
{
    UIViewController *presentingVC = self;
    UIViewController *root = self;
    while (root.parentViewController) {
        root = root.parentViewController;
    }
    UIModalPresentationStyle orginalStyle = root.modalPresentationStyle;
    root.modalPresentationStyle = UIModalPresentationCurrentContext;
    [presentingVC presentViewController:viewControllerToPresent animated:YES completion:^{
        root.modalPresentationStyle = orginalStyle;
    }];
}
@end

If you have to use a table, you can put a link into each table cell:

<table>
  <tbody>
    <tr>
      <td><a href="person1.html">John Smith</a></td>
      <td><a href="person1.html">123 Fake St</a></td>
      <td><a href="person1.html">90210</a></td>
    </tr>
    <tr>
      <td><a href="person2.html">Peter Nguyen</a></td>
      <td><a href="person2.html">456 Elm Ave</a></td>
      <td><a href="person2.html">90210</a></td>
    </tr>
  </tbody>
</table>

And make the links fill up the entire cells:

table tbody tr td a {
  display: block;
  width: 100%;
  height: 100%;
}

If you are able to use <div>s instead of a table, your HTML can be a lot simpler, and you won't get "gaps" in the links, between the table cells:

<div class="myTable">
  <a href="person1.html">
    <span>John Smith</span>
    <span>123 Fake St</span>
    <span>90210</span>
  </a>
  <a href="person2.html">
    <span>Peter Nguyen</span>
    <span>456 Elm Ave</span>
    <span>90210</span>
  </a>
</div>

Here is the CSS that goes with the <div> method:

.myTable {
  display: table;
}
.myTable a {
  display: table-row;
}
.myTable a span {
  display: table-cell;
  padding: 2px; /* this line not really needed */
}

go to the url about:config and paste each line:

network.http.keep-alive.timeout;10
network.http.connection-retry-timeout;10
network.http.pipelining.read-timeout;5
network.http.connection-timeout;10

If you need to mutate the dictionary while enumerating:

for (NSString* key in xyz.allKeys) {
    [xyz setValue:[NSNumber numberWithBool:YES] forKey:key];
}

This worked for me:

mv xyz.war ./tmp
cd tmp
jar -xvf xyz.war
rm -rf WEB-INF/lib/zookeeper-3.4.10.jar
rm -rf xyz.war
jar -cvf xyz.war *
mv xyz.war ../
cd ..

Since Bootstrap v4.1 you can add table-borderless to your table, see official documentation:

<table class='table table-borderless'>

Go to your project folder\app\src\main\res\mipmap-mdpi\ic_launcher.png

You will see 5 mipmap folders. Replace the icon inside of the each mipmap folder, with the icon you want.

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

You can send intent MASTER_CLEAR in adb:

adb shell am broadcast -a android.intent.action.MASTER_CLEAR

or as root

adb shell  "su -c 'am broadcast -a android.intent.action.MASTER_CLEAR'"

So if condition equals the value you want then the php document will run "include" and include will add that document to the current window for example:

`

<?php
$isARequest = true;
if ($isARequest){include('request.html');}/*So because $isARequest is true then it will include request.html but if its not a request then it will insert isNotARequest;*/
else if (!$isARequest) {include('isNotARequest.html')}
?>

`

Here is solution that work for me: CSS:

#uploadtruefield {
    left: 225px;
    opacity: 0;
    position: absolute;
    right: 0;
    top: 266px;
    opacity:0;
    -moz-opacity:0;
    filter:alpha(opacity:0);
    width: 270px;
    z-index: 2;
}

.uploadmask {
    background:url(../img/browse.gif) no-repeat 100% 50%;
}
#uploadmaskfield{
    width:132px;
}

HTML with "small" JQuery help:

<div class="uploadmask">
    <input id="uploadmaskfield" type="text" name="uploadmaskfield">
</div>
<input id="uploadtruefield"  type="file" onchange="$('#uploadmaskfield').val(this.value)" >

Just be sure that maskfied is covered compeltly by true upload field.

If you don't have permissions to change your default DB you could manually select a different DB at the top of your queries...

USE [SomeOtherDb]
SELECT 'I am now using a different DB'

Will work as long as you have permission to the other DB

If you have more than one join you could use comma separated USING statements:

DELETE 
FROM 
      AAA AS a 
USING 
      BBB AS b,
      CCC AS c
WHERE 
      a.id = b.id 
  AND a.id = c.id
  AND a.uid = 12345 
  AND c.gid = 's434sd4'

Don't use wsgiref for production. Use Apache and mod_wsgi, or something else.

We continue to see these connection resets, sometimes frequently, with wsgiref (the backend used by the werkzeug test server, and possibly others like the Django test server). Our solution was to log the error, retry the call in a loop, and give up after ten failures. httplib2 tries twice, but we needed a few more. They seem to come in bunches as well - adding a 1 second sleep might clear the issue.

We've never seen a connection reset when running through Apache and mod_wsgi. I don't know what they do differently, (maybe they just mask them), but they don't appear.

When we asked the local dev community for help, someone confirmed that they see a lot of connection resets with wsgiref that go away on the production server. There's a bug there, but it is going to be hard to find it.

According to the documentation:

The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used in any subsequent Dockerfile instruction.

Also, in the Docker best practices it recommends you to use it:

... you should use WORKDIR instead of proliferating instructions like RUN cd … && do-something, which are hard to read, troubleshoot, and maintain.

I would suggest to keep it.

I think you can refactor your Dockerfile to something like:

FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ] 

When you use setcookie, you can either set the expiration time to 0 or simply omit the parametre - the cookie will then expire at the end of session (ie, when you close the browser).

NOTE: While my advice was true many years ago, Oracle's optimizer has improved so that the location of the where definitely no longer matters here. However preferring UNION ALL vs UNION will always be true, and portable SQL should avoid depending on optimizations that may not be in all databases.

Short answer, you want the WHERE before the UNION and you want to use UNION ALL if at all possible. If you are using UNION ALL then check the EXPLAIN output, Oracle might be smart enough to optimize the WHERE condition if it is left after.

The reason is the following. The definition of a UNION says that if there are duplicates in the two data sets, they have to be removed. Therefore there is an implicit GROUP BY in that operation, which tends to be slow. Worse yet, Oracle's optimizer (at least as of 3 years ago, and I don't think it has changed) doesn't try to push conditions through a GROUP BY (implicit or explicit). Therefore Oracle has to construct larger data sets than necessary, group them, and only then gets to filter. Thus prefiltering wherever possible is officially a Good Idea. (This is, incidentally, why it is important to put conditions in the WHERE whenever possible instead of leaving them in a HAVING clause.)

Furthermore if you happen to know that there won't be duplicates between the two data sets, then use UNION ALL. That is like UNION in that it concatenates datasets, but it doesn't try to deduplicate data. This saves an expensive grouping operation. In my experience it is quite common to be able to take advantage of this operation.

Since UNION ALL does not have an implicit GROUP BY in it, it is possible that Oracle's optimizer knows how to push conditions through it. I don't have Oracle sitting around to test, so you will need to test that yourself.

You can simply use the following command:-

tail -NUMBER_OF_LINES FILE_NAME

e.g tail -100 test.log

• will fetch the last 100 lines from test.log

In case, if you want the output of the above in a separate file then you can pipes as follows:-

tail -NUMBER_OF_LINES FILE_NAME > OUTPUT_FILE_NAME

e.g tail -100 test.log > output.log

• will fetch the last 100 lines from test.log and store them into a new file output.log)

I had the same issue in a Windows Service. All keys where in the right place in the registry. The build of the service was done for x86 and I still got the exception. I found out about CorFlags.exe

Run this on your service.exe without flags to verify if you run under 32 bit. If not run it with the flag /32BIT+ /Force (Force only for signed assemblies)

If you have UAC turned you can get the following error: corflags : error CF001 : Could not open file for writing Give the user full control on the assemblies.

It is just equally spaced hues around the color wheel, starting from 15:

gg_color_hue <- function(n) {
  hues = seq(15, 375, length = n + 1)
  hcl(h = hues, l = 65, c = 100)[1:n]
}

For example:

n = 4
cols = gg_color_hue(n)

dev.new(width = 4, height = 4)
plot(1:n, pch = 16, cex = 2, col = cols)

I solved this problem with using the following steps:

1. File -> Import

2. Click General then select Existing Projects into Workspace

3. Click Next

4. Browse the directory of the project

5. Click Finish!

It worked for me

Actualy the .*? only works in perl. I am not sure what the equivalent grep extended regexp syntax would be. Fortunately you can use perl syntax with grep so grep -P would work but grep -E which is same as egrep would not work (it would be greedy).

See also: http://blog.vinceliu.com/2008/02/non-greedy-regular-expression-matching.html

Size of a pointer should be 8 byte on any 64-bit C/C++ compiler, but not necessarily size of int.

As Davide Gualano has been told. This one

$("#myDiv").load("myScript.php?var=x&var2=y&var3=z")

use GET method for sending the request, and this one

$("#myDiv").load("myScript.php", {var:x, var2:y, var3:z})

use POST method for sending the request. But any limitation that is applied to each method (post/get) is applied to the alternative usages that has been mentioned in the question.

For example: url length limits the amount of sending data in GET method.

We had the same issue, using Plesk Onyx 17. Instead of messing up with rights etc., solution was to add nginx user into psacln group, in which all the other domain owners (users) were:

usermod -aG psacln nginx

Now nginx has rights to access .htaccess or any other file necessary to properly show the content.

On the other hand, also make sure that Apache is in psaserv group, to serve static content:

usermod -aG psaserv apache

And don't forget to restart both Apache and Nginx in Plesk after! (and reload pages with Ctrl-F5)

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

This works, at least in Android API 15

ImageView = imgv;
Resources res = getResources(); // need this to fetch the drawable
Drawable draw = res.getDrawable( R.drawable.image_name_in_drawable );
imgv.setImageDrawable(draw);

You could use setImageResource(), but the documentation specifies that "does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup ... consider using setImageDrawable() or setImageBitmap()." as stated by chetto

To convert a valid JSON string back, you can use the json_decode() method.

To convert it back to an object use this method:

$jObj = json_decode($jsonString);

And to convert it to a associative array, set the second parameter to true:

$jArr = json_decode($jsonString, true);

By the way to convert your mentioned string back to either of those, you should have a valid JSON string. To achieve it, you should do the following:

1. In the Coords array, remove the two " (double quote marks) from the start and end of the object.
2. The objects in an array are comma seprated (,), so add commas between the objects in the Coords array..

And you will have a valid JSON String..

Here is your JSON String I converted to a valid one: http://pastebin.com/R16NVerw

you could use a defaultdict. It will let you set dictionary values without worrying if the key already exists. If you access a key that has not been initialized yet it will return a value you specify (in the below example it will return None)

from collections import defaultdict
your_dict = defaultdict(lambda : None)

Try to replace it with °, and also to set the charset to utf-8, as Martin suggests.

°C will get you something like this:

Bitcode refers to to the type of code: "LLVM Bitcode" that is sent to iTunes Connect. This allows Apple to use certain calculations to re-optimize apps further (e.g: possibly downsize executable sizes). If Apple needs to alter your executable then they can do this without a new build being uploaded.

This differs from: Slicing which is the process of Apple optimizing your app for a user's device based on the device's resolution and architecture. Slicing does not require Bitcode. (Ex: only including @2x images on a 5s)

App Thinning is the combination of slicing, bitcode, and on-demand resources

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Apple Documentation on App Thinning

I usually use this workaround:

try:
    from .mymodule import myclass
except Exception: #ImportError
    from mymodule import myclass

Which means your IDE should pick up the right code location and the python interpreter will manage to run your code.

Alternatively if adding extra library such as hamcrest is not desirable, the logic can be implemented as utility method using junit dependency only:

public static void assertGreaterThan(int greater, int lesser) {
    assertGreaterThan(greater, lesser, null);
}

public static void assertGreaterThan(int greater, int lesser, String message) {
    if (greater <= lesser) {
        fail((StringUtils.isNotBlank(message) ? message + " ==> " : "") +
                "Expected: a value greater than <" + lesser + ">\n" +
                "But <" + greater + "> was " + (greater == lesser ? "equal to" : "less than") + " <" + lesser + ">");
    }
}

You can use w.setMenu(null) or set frame: false (this also removes buttons for close, minimize and maximize options) on your window. See setMenu() or BrowserWindow(). Also check this thread

Electron now has win.removeMenu() (added in v5.0.0), to remove application menus instead of using win.setMenu(null).

Electron 7.1.x seems to have a bug where win.removeMenu() doesn't work. The only workaround is to use Menu.setApplicationMenu(null)

In CLI

$ webpack --version
    
webpack-cli 4.1.0
    
webpack 5.3.2

In Code (node runtime)

process.env.npm_package_devDependencies_webpack // ^5.3.2

or

process.env.npm_package_dependencies_webpack // ^5.3.2

In Plugin

compiler.webpack.version // 5.3.2

Another way is using HashSet:

var hash = new HashSet<int>();
var duplicates = list.Where(i => !hash.Add(i));

If you want unique values in your duplicates list:

var myhash = new HashSet<int>();
var mylist = new List<int>(){1,1,2,2,3,3,3,4,4,4};
var duplicates = mylist.Where(item => !myhash.Add(item)).Distinct().ToList();

Here is the same solution as a generic extension method:

public static class Extensions
{
  public static IEnumerable<TSource> GetDuplicates<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> selector, IEqualityComparer<TKey> comparer)
  {
    var hash = new HashSet<TKey>(comparer);
    return source.Where(item => !hash.Add(selector(item))).ToList();
  }

  public static IEnumerable<TSource> GetDuplicates<TSource>(this IEnumerable<TSource> source, IEqualityComparer<TSource> comparer)
  {
    return source.GetDuplicates(x => x, comparer);      
  }

  public static IEnumerable<TSource> GetDuplicates<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> selector)
  {
    return source.GetDuplicates(selector, null);
  }

  public static IEnumerable<TSource> GetDuplicates<TSource>(this IEnumerable<TSource> source)
  {
    return source.GetDuplicates(x => x, null);
  }
}

I tried both .empty() as well as .remove() for my dropdown and both were slow. Since I had almost 4,000 options there.

I used .html("") which is much faster in my condition.
Which is below

  $(dropdown).html("");

On Windows: if you had to mount two directories E:\data\dev & E:\data\dev2

Use:

docker run -v E:\data\dev:c:/downloads -v E:\data\dev2 c:/downloads2 -i --publish 1111:80 -P SomeBuiltContainerName:SomeLabel

To loop all rows in a dataframe you can use:

for x in range(len(date_example.index)):
    print date_example['Date'].iloc[x]

Use FirstOrDefault insted of SingleOrDefault..

SingleOrDefault returns a SINGLE element or null if no element is found. If 2 elements are found in your Enumerable then it throws the exception you are seeing

FirstOrDefault returns the FIRST element it finds or null if no element is found. so if there are 2 elements that match your predicate the second one is ignored

   public int GetPackage(int id,int emp)
           {
             int getpackages=Convert.ToInt32(EmployerSubscriptionPackage.GetAllData().Where(x
   => x.SubscriptionPackageID ==`enter code here` id && x.EmployerID==emp ).FirstOrDefault().ID);
               return getpackages;
           }

 1. var EmployerId = Convert.ToInt32(Session["EmployerId"]);
               var getpackage = GetPackage(employerSubscription.ID, EmployerId);

No. The only you can do is to add content (and not an element) using :before or :after pseudo-element.

More information: http://www.w3.org/TR/CSS2/generate.html#before-after-content

First, you do not need android:process=":remote", so please remove it, since all it will do is take up extra RAM for no benefit.

Second, since the <service> element contains an action string, use it:

public void onCreate(Bundle savedInstanceState) {    
      super.onCreate(savedInstanceState);  
      Intent intent=new Intent("com.sample.service.serviceClass");  
      this.startService(intent);
}

I solved the same problem by installing "matplotlib".

Another option would be as the return value for the stored procedure (I don't suggest this though, as that's usually best for error values).

I've included it as both when it's inserting a single row in cases where the stored procedure was being consumed by both other SQL procedures and a front-end which couldn't work with OUTPUT parameters (IBATIS in .NET I believe):

CREATE PROCEDURE My_Insert
    @col1            VARCHAR(20),
    @new_identity    INT    OUTPUT
AS
BEGIN
    SET NOCOUNT ON

    INSERT INTO My_Table (col1)
    VALUES (@col1)

    SELECT @new_identity = SCOPE_IDENTITY()

    SELECT @new_identity AS id

    RETURN
END

The output parameter is easier to work with in T-SQL when calling from other stored procedures IMO, but some programming languages have poor or no support for output parameters and work better with result sets.

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

One interesting fact about the obj directory: If you have publishing set up in a web project, the files that will be published are staged to obj\Release\Package\PackageTmp. If you want to publish the files yourself rather than use the integrated VS feature, you can grab the files that you actually need to deploy here, rather than pick through all the digital debris in the bin directory.

I know the question's for C++, but if anyone needs a good ol' fashioned C function to do this:

/*  returns 1 iff str ends with suffix  */
int str_ends_with(const char * str, const char * suffix) {

  if( str == NULL || suffix == NULL )
    return 0;

  size_t str_len = strlen(str);
  size_t suffix_len = strlen(suffix);

  if(suffix_len > str_len)
    return 0;

  return 0 == strncmp( str + str_len - suffix_len, suffix, suffix_len );
}

Set the main div CSS to somthing like:

<style>
    .wrapper{
        display:flex;
        flex-direction: column;
    }
</style>

<div id="wrapper">
        <div id="inner1">This is inner div 1</div>
        <div id="inner2">This is inner div 2</div>
</div>

For more flexbox CSS refer: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

Change the less-than operator to a greater-than-or-equal-to operator:

}elseif($("#seats").val() >= 99999){

Giphy Gotcha

After following the 2 requirements listed above (must end in .gif and using the image syntax), if you are having trouble with a gif from giphy:

Be sure you have the correct giphy url! You can't just add .gif to the end of this one and have it work.

If you just copy the url from a browser, you will get something like:

https://giphy.com/gifs/gol-automaton-game-of-life-QfsvYoBSSpfbtFJIVo

You need to instead click on "Copy Link" and then grab the "GIF Link" specifically. Notice the correct one points to media.giphy.com instead of just giphy.com:

https://media.giphy.com/media/QfsvYoBSSpfbtFJIVo/giphy.gif

Though I tend to agree with @AlekDavis' comment, there are nonetheless several ways to do this in the NT shell.

The approach I would take advantage of the SHIFT command and IF conditional branching, something like this...

@ECHO OFF

SET man1=%1
SET man2=%2
SHIFT & SHIFT

:loop
IF NOT "%1"=="" (
    IF "%1"=="-username" (
        SET user=%2
        SHIFT
    )
    IF "%1"=="-otheroption" (
        SET other=%2
        SHIFT
    )
    SHIFT
    GOTO :loop
)

ECHO Man1 = %man1%
ECHO Man2 = %man2%
ECHO Username = %user%
ECHO Other option = %other%

REM ...do stuff here...

There is an open source HTML5/javascript reader available called Trapeze though its still in its early stages.

Demo site: https://brendandahl.github.io/trapeze-reader/demos/

Github page: https://github.com/brendandahl/trapeze-reader

Disclaimer: I'm the author.

You may have not set the output file.

I have created an application to increment the file version automatically.

1. Download Application

2. add the following line to pre-build event command line

   C:\temp\IncrementFileVersion.exe $(SolutionDir)\Properties\AssemblyInfo.cs

3. Build the project

To keep it simple the app only throws messages if there is an error, to confirm it worked fine you will need to check the file version in 'Assembly Information'

Note : You will have to reload the solution in Visual studio for 'Assembly Information' button to populate the fields, however your output file will have the updated version.

For suggestions and requests please email me at [email protected]

To use offline Java API Documentation in Eclipse, you need to download it first. The link for Java docs are (last updated on 2013-10-21):

Java 6
Page: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u25-doc-download-355137.html
Direct: http://download.oracle.com/otn-pub/java/jdk/6u30-b12/jdk-6u30-apidocs.zip

Java 7

Java 9
Page:http://www.oracle.com/technetwork/java/javase/documentation/jdk9-doc-downloads-3850606.html

1. Extract the zip file in your local directory.
2. From eclipse Window --> Preferences --> Java --> "Installed JREs" select available JRE (jre6: C:\Program Files (x86)\Java\jre6 for instance) and click Edit.
3. Select all the "JRE System libraries" using Control+A.
4. Click "Javadoc Location"
5. Change "Javadoc location path:" from "http://download.oracle.com/javase/6/docs/api/" to "file:/E:/Java/docs/api/".

It must work as it works for me. I don't need Internet connection to view Java API Documentation in Eclipse anymore.

You can overcome this error in two simple ways

First way

using namespace std;
include <string>
// then you can use string class the normal way

Second way

// after including the class string in your cpp file as follows
include <string>
/*Now when you are using a string class you have to put **std::** before you write 
string as follows*/
std::string name; // a string declaration

I have great news: this will be in Compose 1.3!

I'm using it in the current RC (RC1) like this:

rng:
  build: rng
  extra_hosts:
    seed: 1.2.3.4
    tree: 4.3.2.1

I needed to do the same thing, so have written some JavaScript to enable this, using the onSelect and beforeShowDay events. It maintains its own array of selected dates, so unfortunately doesn't integrate with a textbox showing the current date, etc. I'm just using it as an inline control, and I can then query the array for the currently selected dates.
I used this code as a basis.

<script type="text/javascript">
// Maintain array of dates
var dates = new Array();

function addDate(date) {
    if (jQuery.inArray(date, dates) < 0) 
        dates.push(date);
}

function removeDate(index) {
    dates.splice(index, 1);
}

// Adds a date if we don't have it yet, else remove it
function addOrRemoveDate(date) {
    var index = jQuery.inArray(date, dates);
    if (index >= 0) 
        removeDate(index);
    else 
        addDate(date);
}

// Takes a 1-digit number and inserts a zero before it
function padNumber(number) {
    var ret = new String(number);
    if (ret.length == 1) 
        ret = "0" + ret;
    return ret;
}

jQuery(function () {
    jQuery("#datepicker").datepicker({
        onSelect: function (dateText, inst) {
            addOrRemoveDate(dateText);
        },
        beforeShowDay: function (date) {
            var year = date.getFullYear();
            // months and days are inserted into the array in the form, e.g "01/01/2009", but here the format is "1/1/2009"
            var month = padNumber(date.getMonth() + 1);
            var day = padNumber(date.getDate());
            // This depends on the datepicker's date format
            var dateString = month + "/" + day + "/" + year;

            var gotDate = jQuery.inArray(dateString, dates);
            if (gotDate >= 0) {
                // Enable date so it can be deselected. Set style to be highlighted
                return [true, "ui-state-highlight"];
            }
            // Dates not in the array are left enabled, but with no extra style
            return [true, ""];
        }
    });
});
</script>

List<WebElement> myElements = driver.findElements(By.xpath("some/path//a"));
        System.out.println("Size of List: "+myElements.size());
        for(WebElement e : myElements) 
        {        
            System.out.print("Text within the Anchor tab"+e.getText()+"\t");
            System.out.println("Anchor: "+e.getAttribute("href"));
        }

//NOTE: "//a" will give you all the anchors there on after the point your XPATH has reached.

This exception can raise when you handle Deep linking or URL for a browser, if there is no default installed. In case of Deep linking there may be no application installed that can process a link in format myapp://mylink.

You can use the tangerine solution for API up to 29:

private fun openUrl(url: String) {
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    val activityInfo = intent.resolveActivityInfo(packageManager, intent.flags)
    if (activityInfo?.exported == true) {
        startActivity(intent)
    } else {
        Toast.makeText(
            this,
            "No application that can handle this link found",
            Toast.LENGTH_SHORT
        ).show()
    }
}

For API >= 30 see intent.resolveActivity returns null in API 30.

In case anyone would be searching - I created utility for automated import of xlsx files into google spreadsheet: xls2sheets. One can do it automatically via setting up the cronjob for ./cmd/sheets-refresh, readme describes it all. Hope that would be of use.

I found this piece of code somewhere in the web. Maybe it helps you and I give you an update so far I accomodated it for the same purpose... Maybe I don't.... who the futt knows... with all the nogodders and dobedders in here :-/

One area where I found mmap() to not be an advantage was when reading small files (under 16K). The overhead of page faulting to read the whole file was very high compared with just doing a single read() system call. This is because the kernel can sometimes satisify a read entirely in your time slice, meaning your code doesn't switch away. With a page fault, it seemed more likely that another program would be scheduled, making the file operation have a higher latency.

This is exactly what the OUTPUT clause in SQL Server 2005 onwards is excellent for.

EXAMPLE

CREATE TABLE [dbo].[test_table](
    [LockId] [int] IDENTITY(1,1) NOT NULL,
    [StartTime] [datetime] NULL,
    [EndTime] [datetime] NULL,
PRIMARY KEY CLUSTERED 
(
    [LockId] ASC
) ON [PRIMARY]
) ON [PRIMARY]

INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 07','2009 JUL 07')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 08','2009 JUL 08')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 09','2009 JUL 09')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 10','2009 JUL 10')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 11','2009 JUL 11')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 12','2009 JUL 12')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 13','2009 JUL 13')

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* -- INSERTED reflect the value after the UPDATE, INSERT, or MERGE statement is completed 
WHERE
    StartTime > '2009 JUL 09'

Results in the following being returned

    LockId StartTime                EndTime
-------------------------------------------------------
4      2011-07-01 00:00:00.000  2009-07-10 00:00:00.000
5      2011-07-01 00:00:00.000  2009-07-11 00:00:00.000
6      2011-07-01 00:00:00.000  2009-07-12 00:00:00.000
7      2011-07-01 00:00:00.000  2009-07-13 00:00:00.000

In your particular case, since you cannot use aggregate functions with OUTPUT, you need to capture the output of INSERTED.* in a table variable or temporary table and count the records. For example,

DECLARE @temp TABLE (
  [LockId] [int],
  [StartTime] [datetime] NULL,
  [EndTime] [datetime] NULL 
)

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* INTO @temp
WHERE
    StartTime > '2009 JUL 09'


-- now get the count of affected records
SELECT COUNT(*) FROM @temp

Wikipedia has a very good answer http://en.wikipedia.org/wiki/Universally_unique_identifier#Collisions

the number of random version 4 UUIDs which need to be generated in order to have a 50% probability of at least one collision is 2.71 quintillion, computed as follows:

...

This number is equivalent to generating 1 billion UUIDs per second for about 85 years, and a file containing this many UUIDs, at 16 bytes per UUID, would be about 45 exabytes, many times larger than the largest databases currently in existence, which are on the order of hundreds of petabytes.

...

Thus, for there to be a one in a billion chance of duplication, 103 trillion version 4 UUIDs must be generated.

What you need is a date template filter.

e.g:

<td>Joined {{user.date_created|date:"F Y" }}<td>

This returns Joined December 2018

1. No, it's less fast but not that slow
2. For a backup program it's maybe necessary to have something even faster than MD5

All in all, I'd say that MD5 in addition to the file name is absolutely safe. SHA-256 would just be slower and harder to handle because of its size.

You could also use something less secure than MD5 without any problem. If nobody tries to hack your file integrity this is safe, too.

I know its pretty old but I just encounter the problem and there is what I saw in the SQL doc :

[For best results when using BETWEEN with date or time values,] use CAST() to explicitly convert the values to the desired data type. Examples: If you compare a DATETIME to two DATE values, convert the DATE values to DATETIME values. If you use a string constant such as '2001-1-1' in a comparison to a DATE, cast the string to a DATE.

I assume it's better to use STR_TO_DATE since they took the time to make a function just for that and also the fact that i found this in the BETWEEN doc...

Since git 1.8 you can do

git submodule update --remote --merge

This will update the submodule to the latest remote commit. You will then need to commit the change so the gitlink in the parent repository is updated

git commit

And then push the changes as without this, the SHA-1 identity the pointing to the submodule won't be updated and so the change won't be visible to anyone else.

Default.sublime-theme file works unless you have installed a theme. If you did, go to your theme's github repo and download the your_theme.sublime-theme file and put it in your 'User' folder. In that file, find "class": "sidebar_label", add "font.size":16 to that section.

Just want to add to the excellent answer of @Lin:

5) B. If you don't have SQL Management Studio, go to "SQL Server Object Explorer". If you cannot see your project db in the localdb "SQL Server Object Explorer", then click on "Add SQL server" button to add it to the list manually. Then you can delete the db from the list.

What about this:

with open("your_csv_file.csv", "w") as f:
    f.write("\n".join(text))

str.join() Return a string which is the concatenation of the strings in iterable. The separator between elements is the string providing this method.

ok very simple first go to 1. res-valuse and open colors.xml 2.copy 1 of the defined text their for example #FF4081 and change name for instance i changed to white and change its value for instance i changed to #FFFFFF for white value like this

<color name="White">#FFFFFF</color>

then inside your button add this line

 b3.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.White));

ok b3 is the name of my button so changed of the name of ur button all others will be same if u use white color if you change different color then change white to the name of your color but first you have define that color in colors.xml like i explained in pont 2

document.getElementsByClassName returns an HTMLCollection(an array-like object) of all elements matching the class name. The style property is defined for Element not for HTMLCollection. You should access the first element using the bracket(subscript) notation.

document.getElementsByClassName('appBanner')[0].style.visibility = 'hidden';

Updated jsFiddle

To change the style rules of all elements matching the class, using the Selectors API:

[].forEach.call(document.querySelectorAll('.appBanner'), function (el) {
  el.style.visibility = 'hidden';
});

If for...of is available:

for (let el of document.querySelectorAll('.appBanner')) el.style.visibility = 'hidden';

Graphic answer to this question

Here is a site with a clear explanation and graphical illustration of using git merge --no-ff:

Until I saw this, I was completely lost with git. Using --no-ff allows someone reviewing history to clearly see the branch you checked out to work on. (that link points to github's "network" visualization tool) And here is another great reference with illustrations. This reference complements the first one nicely with more of a focus on those less acquainted with git.

Basic info for newbs like me

If you are like me, and not a Git-guru, my answer here describes handling the deletion of files from git's tracking without deleting them from the local filesystem, which seems poorly documented but often occurrence. Another newb situation is getting current code, which still manages to elude me.

Example Workflow

I updated a package to my website and had to go back to my notes to see my workflow; I thought it useful to add an example to this answer.

My workflow of git commands:

git checkout -b contact-form
(do your work on "contact-form")
git status
git commit -am  "updated form in contact module"
git checkout master
git merge --no-ff contact-form
git branch -d contact-form
git push origin master

Below: actual usage, including explanations.
Note: the output below is snipped; git is quite verbose.

$ git status
# On branch master
# Changed but not updated:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   ecc/Desktop.php
#       modified:   ecc/Mobile.php
#       deleted:    ecc/ecc-config.php
#       modified:   ecc/readme.txt
#       modified:   ecc/test.php
#       deleted:    passthru-adapter.igs
#       deleted:    shop/mickey/index.php
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       ecc/upgrade.php
#       ecc/webgility-config.php
#       ecc/webgility-config.php.bak
#       ecc/webgility-magento.php

Notice 3 things from above:
1) In the output you can see the changes from the ECC package's upgrade, including the addition of new files.
2) Also notice there are two files (not in the /ecc folder) I deleted independent of this change. Instead of confusing those file deletions with ecc, I'll make a different cleanup branch later to reflect those files' deletion.
3) I didn't follow my workflow! I forgot about git while I was trying to get ecc working again.

Below: rather than do the all-inclusive git commit -am "updated ecc package" I normally would, I only wanted to add the files in the /ecc folder. Those deleted files weren't specifically part of my git add, but because they already were tracked in git, I need to remove them from this branch's commit:

$ git checkout -b ecc
$ git add ecc/*
$ git reset HEAD passthru-adapter.igs
$ git reset HEAD shop/mickey/index.php
Unstaged changes after reset:
M       passthru-adapter.igs
M       shop/mickey/index.php

$ git commit -m "Webgility ecc desktop connector files; integrates with Quickbooks"

$ git checkout master
D       passthru-adapter.igs
D       shop/mickey/index.php
Switched to branch 'master'
$ git merge --no-ff ecc
$ git branch -d ecc
Deleted branch ecc (was 98269a2).
$ git push origin master

Script for automating the above

Having used this process 10+ times in a day, I have taken to writing batch scripts to execute the commands, so I made an almost-proper git_update.sh <branch> <"commit message"> script for doing the above steps. Here is the Gist source for that script.

Instead of git commit -am I am selecting files from the "modified" list produced via git status and then pasting those in this script. This came about because I made dozens of edits but wanted varied branch names to help group the changes.

First you should check how many commits you have:

git log

There are two status:

One is that there are only two commits:

For example:

commit A
commit B

(In this case, you can't use git rebase to do) you need to do following.

$ git reset --soft HEAD^1

$ git commit --amend

Another is that there are more than two commits; you want to merge commit C and D.

For example:

commit A
commit B
commit C
commit D

(under this condition, you can use git rebase)

git rebase -i B

And than use "squash" to do. The rest thins is very easy. If you still don't know, please read http://zerodie.github.io/blog/2012/01/19/git-rebase-i/

You should definitely check out django-q! It requires no additional configuration and has quite possibly everything needed to handle any production issues on commercial projects.

It's actively developed and integrates very well with django, django ORM, mongo, redis. Here is my configuration:

# django-q

Q_CLUSTER = {
    # Match recommended settings from docs.
    'name': 'DjangoORM',
    'workers': 4,
    'queue_limit': 50,
    'bulk': 10,
    'orm': 'default',

# Custom Settings
# ---------------
# Limit the amount of successful tasks saved to Django.
'save_limit': 10000,

# See https://github.com/Koed00/django-q/issues/110.
'catch_up': False,

# Number of seconds a broker will wait for a cluster to finish a task before presenting it again. This needs to be
# longer than `timeout`, otherwise the same task will be processed multiple times.

One caveat: in .NET the linefeed is "\r\n". So if you're loading your text from a file, you might have to use that instead of just "\n"

edit> as samuel pointed out in the comments, "\r\n" is not .NET specific, but is windows specific.

You can use this:

response.sendRedirect(String.format("%s%s", request.getContextPath(), "/views/equipment/createEquipment.jsp"));

The last part is your path in your web-app

iOS includes built in support for base64 encoding and decoding. If you look at resolv.h you should see the two functions b64_ntop and b64_pton . The Square SocketRocket library provides a reasonable example of how to use these functions from objective-c.

These functions are pretty well tested and reliable - unlike many of the implementations you may find in random internet postings. Don't forget to link against libresolv.dylib.

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

Replace this :

$('#subscription_order_form').submit(function(e){
  e.preventDefault();
});

with this:

$('#subscription_order_form').on('keydown', function(e){
    if (e.which===13) e.preventDefault();
});

FIDDLE

That will prevent the form from submitting when Enter key is pressed as it prevents the default action of the key, but the form will submit normally on click.

The space before the = is interpreted as part of the name, and the space after it (as well as the quotation marks) are interpreted as part of the value. So the variable you’ve created can be referenced with %location %. If that’s not what you want, remove the extra space(s) in the definition.

I think this is bit round-about explanation but still it clarifies using real life example.

Small Example:

Let's say playing an audio involves three steps:

1. Getting the compressed song from harddisk
2. Decompress the audio.
3. Play the uncompressed audio.

If your audio player does step 1,2,3 sequentially for every song then it is synchronous. You will have to wait for some time to hear the song till the song actually gets fetched and decompressed.

If your audio player does step 1,2,3 independent of each other, then it is asynchronous. ie. While playing audio 1 ( step 3), if it fetches audio 3 from harddisk in parallel (step 1) and it decompresses the audio 2 in parallel. (step 2 ) You will end up in hearing the song without waiting much for fetch and decompress.

Perhaps a more pythonic way of doing so.

from numpy import *
import math
import matplotlib.pyplot as plt

t = linspace(0,2*math.pi,400)
a = sin(t)
b = cos(t)
c = a + b

plt.plot(t, a, t, b, t, c)
plt.show()

On your user model just add a 'hasRole' method like below

public boolean hasRole(String auth) {
    for (Role role : roles) {
        if (role.getName().equals(auth)) { return true; }
    }
    return false;
}

I usually use it to check if the authenticated user has the role admin as follows

Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); // This gets the authentication
User authUser = (User) authentication.getPrincipal(); // This gets the logged in user
authUser.hasRole("ROLE_ADMIN") // This returns true or false

Here's a solution that uses more modern syntax and is less verbose than the ones already provided:

const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");

video.addEventListener('play', () => {
  function step() {
    ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
    requestAnimationFrame(step)
  }
  requestAnimationFrame(step);
})

Some useful links:

• MDN Documentation for window.requestAnimationFrame()
• Can I use requestAnimationFrame?

You can use the include? method:

my_string = "abcdefg"
if my_string.include? "cde"
   puts "String includes 'cde'"
end

UPDATE T1,T2 
INNER JOIN T1 ON  T1.Brands = T2.Brands

search your code you must be referring to color in color.xml in an xml drawable. go and give hex code instead of referencing....

Example: in drawable.xml you must have called

android:fillColor="@color/blue"

change it to android:fillColor="#ffaacc" hope it solve your problem...

(This is the KISS answer.)

Let's say you have several .java files in the current directory:

$ ls -1 *.java
javaFileName1.java
javaFileName2.java

Let's say each of them have a main() method (so they are programs, not libs), then to compile them do:

javac *.java -d .

This will generate as many subfolders as "packages" the .java files are associated to. In my case all java files where inside under the same package name packageName, so only one folder was generated with that name, so to execute each of them:

java -cp . packageName.javaFileName1
java -cp . packageName.javaFileName2

There are mainly two ways to use JDBC - using Windows authentication and SQL authentication. SQL authentication is probably the easiest. What you can do is something like:

String userName = "username";
String password = "password";

String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB";

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url, userName, password);

after adding sqljdbc4.jar to the build path.

For Window authentication you can do something like:

String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url);

and then add the path to sqljdbc_auth.dll as a VM argument (still need sqljdbc4.jar in the build path).

Please take a look here for a short step-by-step guide showing how to connect to SQL Server from Java using jTDS and JDBC should you need more details. Hope it helps!

add the below with URL Suffix

/override-http-headers-default-settings-x-frame-options

Here is a Node.js implementation that is likely to bit.ly. generate a highly random seven-character string.

It uses Node.js crypto to generate a highly random 25 charset rather than randomly selecting seven characters.

var crypto = require("crypto");
exports.shortURL = new function () {
    this.getShortURL = function () {
        var sURL = '',
            _rand = crypto.randomBytes(25).toString('hex'),
            _base = _rand.length;
        for (var i = 0; i < 7; i++)
            sURL += _rand.charAt(Math.floor(Math.random() * _rand.length));
        return sURL;
    };
}

For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)

  $url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

I customized Tomcat DataSource in Spring-Boot 2.

You can login to mysql and type

mysql> SHOW INNODB STATUS\G

You will have all the output and you should have a better idea of what the error is.

You can use not instead of if like

.Container *:not(a)
{
    color: #fff;
}

angualr uses the lighter version of jquery called as jqlite which means it doesnt have all the features of jQuery. here is a reference in angularjs docs about what you can use from jquery. Angular Element docs

In your case you need to find a div with ID or class name. for class name you can use

var elems =$element.find('div') //returns all the div's in the $elements
    angular.forEach(elems,function(v,k)){
    if(angular.element(v).hasClass('class-name')){
     console.log(angular.element(v));
}}

or you can use much simpler way by query selector

angular.element(document.querySelector('#id'))

angular.element(elem.querySelector('.classname'))

it is not as flexible as jQuery but what

Actually you can find very easy the day a video was created, right-click, property but remember it will only give the details of any copy date of the video but if you do click where it says DETAILS JUST there is the information you need, the original date that the archive was created on. Note that most modern devices will produce this information when you take pictures and videos but others will not.

Include using namespace System.Linq

List<string> stringList = line.Split(',').ToList();

you can make use of it with ease for iterating through each item.

foreach(string str in stringList)
{

}

String.Split() returns an array, hence convert it to a list using ToList()

Here is a perfect way to split the video. I have done it previously, and it's working well for me.

ffmpeg -i C:\xampp\htdocs\videoCutting\movie.mp4 -ss 00:00:00 -t 00:00:05 -async 1 C:\xampp\htdocs\videoCutting\SampleVideoNew.mp4 (For cmd). shell_exec('ffmpeg -i C:\xampp\htdocs\videoCutting\movie.mp4 -ss 00:00:00 -t 00:00:05 -async 1 C:\xampp\htdocs\videoCutting\SampleVideoNew.mp4') (for php).

Please follow this and I am sure it will work perfectly.

The following is also working for me:

ssh <user>@<host>  "cat <filepath>"|pbcopy 

Eclipse needs to see a main method in one of your project's source files in order to determine what kind of project it is so that it can offer the proper run options:

public static void main(String[] args)

Without that method signature (or with a malformed version of that method signature), the Run As menu item will not present any run options.

UPDATE:

As written in this answer,

• Stackdriver Logging is the preferred method of logging now.

• Use console.log() to log to Stackdriver.

Logger.log will either send you an email (eventually) of errors that have happened in your scripts, or, if you are running things from the Script Editor, you can view the log from the last run function by going to View->Logs (still in script editor). Again, that will only show you anything that was logged from the last function you ran from inside Script Editor.

The script I was trying to get working had to do with spreadsheets - I made a spreadsheet todo-checklist type thing that sorted items by priorities and such.

The only triggers I installed for that script were the onOpen and onEdit triggers. Debugging the onEdit trigger was the hardest one to figure out, because I kept thinking that if I set a breakpoint in my onEdit function, opened the spreadsheet, edited a cell, that my breakpoint would be triggered. This is not the case.

To simulate having edited a cell, I did end up having to do something in the actual spreadsheet though. All I did was make sure the cell that I wanted it to treat as "edited" was selected, then in Script Editor, I would go to Run->onEdit. Then my breakpoint would be hit.

However, I did have to stop using the event argument that gets passed into the onEdit function - you can't simulate that by doing Run->onEdit. Any info I needed from the spreadsheet, like which cell was selected, etc, I had to figure out manually.

Anyways, long answer, but I figured it out eventually.

EDIT:

If you want to see the todo checklist I made, you can check it out here

(yes, I know anybody can edit it - that's the point of sharing it!)

I was hoping it'd let you see the script as well. Since you can't see it there, here it is:

function onOpen() {
  setCheckboxes();
};

function setCheckboxes() {
  var checklist = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("checklist");
  var checklist_data_range = checklist.getDataRange();
  var checklist_num_rows = checklist_data_range.getNumRows();
  Logger.log("checklist num rows: " + checklist_num_rows);

  var coredata = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("core_data");
  var coredata_data_range = coredata.getDataRange();

  for(var i = 0 ; i < checklist_num_rows-1; i++) {
    var split = checklist_data_range.getCell(i+2, 3).getValue().split(" || ");
    var item_id = split[split.length - 1];
    if(item_id != "") {
      item_id = parseInt(item_id);
      Logger.log("setting value at ("+(i+2)+",2) to " + coredata_data_range.getCell(item_id+1, 3).getValue());
      checklist_data_range.getCell(i+2,2).setValue(coredata_data_range.getCell(item_id+1, 3).getValue());
    }
  }
}

function onEdit() {
  Logger.log("TESTING TESTING ON EDIT");
  var active_sheet = SpreadsheetApp.getActiveSheet();
  if(active_sheet.getName() == "checklist") {
    var active_range = SpreadsheetApp.getActiveSheet().getActiveRange();
    Logger.log("active_range: " + active_range);
    Logger.log("active range col: " + active_range.getColumn() + "active range row: " + active_range.getRow());
    Logger.log("active_range.value: " + active_range.getCell(1, 1).getValue());
    Logger.log("active_range. colidx: " + active_range.getColumnIndex());
    if(active_range.getCell(1,1).getValue() == "?" || active_range.getCell(1,1).getValue() == "?") {
      Logger.log("made it!");
      var next_cell = active_sheet.getRange(active_range.getRow(), active_range.getColumn()+1, 1, 1).getCell(1,1);
      var val = next_cell.getValue();
      Logger.log("val: " + val);
      var splits = val.split(" || ");
      var item_id = splits[splits.length-1];
      Logger.log("item_id: " + item_id);

      var core_data = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("core_data");
      var sheet_data_range = core_data.getDataRange();
      var num_rows = sheet_data_range.getNumRows();
      var sheet_values = sheet_data_range.getValues();
      Logger.log("num_rows: " + num_rows);

      for(var i = 0; i < num_rows; i++) {
        Logger.log("sheet_values[" + (i) + "][" + (8) + "] = " + sheet_values[i][8]);
        if(sheet_values[i][8] == item_id) {
          Logger.log("found it! tyring to set it...");
          sheet_data_range.getCell(i+1, 2+1).setValue(active_range.getCell(1,1).getValue());
        }
      }

    }
  }

  setCheckboxes();
};

If you want to stream any webpage, you can use the method below.

import java.io.*;
import java.net.*;

public class c {

   public static String getHTML(String urlToRead) throws Exception {
      StringBuilder result = new StringBuilder();
      URL url = new URL(urlToRead);
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      conn.setRequestMethod("GET");
      try (var reader = new BufferedReader(
                  new InputStreamReader(conn.getInputStream()))) {
          for (String line; (line = reader.readLine()) != null; ) {
              result.append(line);
          }
      }
      return result.toString();
   }

   public static void main(String[] args) throws Exception
   {
     System.out.println(getHTML(args[0]));
   }
}

indices = [i for i, s in enumerate(mylist) if 'aa' in s]

May be it's too late. Your code is correct so please check again your url in filebrowserUploadUrl

CKEDITOR.replace( 'editor1', {
    filebrowserUploadUrl: "upload/upload.php" 
} );

And the Upload.php file

if (file_exists("images/" . $_FILES["upload"]["name"]))
{
 echo $_FILES["upload"]["name"] . " already exists. ";
}
else
{
 move_uploaded_file($_FILES["upload"]["tmp_name"],
 "images/" . $_FILES["upload"]["name"]);
 echo "Stored in: " . "images/" . $_FILES["upload"]["name"];
}

You say

The string is exactly what was written to the file (with the addition of a "\0" at the end, but I don't think that even does anything).

In fact, it does do something (it causes your code to throw a FormatException:"Invalid character in a Base-64 string") because the Convert.FromBase64String does not consider "\0" to be a valid Base64 character.

  byte[] data1 = Convert.FromBase64String("AAAA\0"); // Throws exception
  byte[] data2 = Convert.FromBase64String("AAAA");   // Works

Solution: Get rid of the zero termination. (Maybe call .Trim("\0"))

Notes:

The MSDN docs for Convert.FromBase64String say it will throw a FormatException when

The length of s, ignoring white space characters, is not zero or a multiple of 4.

-or-

The format of s is invalid. s contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.

and that

The base 64 digits in ascending order from zero are the uppercase characters 'A' to 'Z', lowercase characters 'a' to 'z', numerals '0' to '9', and the symbols '+' and '/'.

If you want it to be List<string>, get rid of the anonymous type and add a .ToList() call:

List<string> list = (from char c in source
                     select c.ToString()).ToList();

I might be wrong, but a solution picking up bits and pieces. Perhaps, as I still learning, is that the functions does many things in the same one. Do not hesitate to correct me, please.

const totalSum = (num) => [...num + ' '].map(Number).reduce((a, b) => a + b);

So we take the parameter and convert it to and arr, adding empty spaces. We do such operation in every single element and push it into a new array with the map method. Once splited, we use reduce to sum all the elements and get the total.

As I said, don't hesitate to correct me or improve the function if you see something that I don't.

Almost forgot, just in case:

const totalSum = (num) => ( num === 0 || num < 0) ? 'I need a positive number' : [...num + ' '].map(Number).reduce((a, b) => a + b);

If negatives numbers or just plain zero go down as parameters. Happy coding to us all.

If anyone is interested, you can have the the offset information for all the consumer groups with the following command:

kafka-consumer-groups --bootstrap-server localhost:9092 --all-groups --describe

The parameter --all-groups is available from Kafka 2.4.0

tl;dr

I know this is old, but getoptlong wasn't mentioned here and it's probably the best way to parse command line arguments today.

Parsing command line arguments

I strongly recommend getoptlong. It's pretty easy to use and works like a charm. Here is an example extracted from the link above

require 'getoptlong'

opts = GetoptLong.new(
    [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
    [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],
    [ '--name', GetoptLong::OPTIONAL_ARGUMENT ]
)

dir = nil
name = nil
repetitions = 1
opts.each do |opt, arg|
    case opt
        when '--help'
            puts <<-EOF
hello [OPTION] ... DIR

-h, --help:
     show help

--repeat x, -n x:
     repeat x times

--name [name]:
     greet user by name, if name not supplied default is John

DIR: The directory in which to issue the greeting.
            EOF
        when '--repeat'
            repetitions = arg.to_i
        when '--name'
            if arg == ''
                name = 'John'
            else
                name = arg
            end
    end
end

if ARGV.length != 1
    puts "Missing dir argument (try --help)"
    exit 0
end

dir = ARGV.shift

Dir.chdir(dir)
for i in (1..repetitions)
    print "Hello"
    if name
        print ", #{name}"
    end
    puts
end

You can call it like this ruby hello.rb -n 6 --name -- /tmp

What OP is trying to do

In this case I think the best option is to use YAML files as suggested in this answer

I know this post is older, but haven't seen a solution that provides the actual information, so I want to share what I use for SQL Server 2012 and above. the link below leads to the screenshot showing the information.

First (so no time is wasted):

SQL Server 2000:
SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')

SQL Server 2005+

The "SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')" is not in use anymore. You can see more details on MSFT documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/serverproperty-transact-sql?view=sql-server-2017

SQL Server 2005 - 2008R2 you would have to:

Using PowerShell: https://www.ryadel.com/en/sql-server-retrieve-product-key-from-an-existing-installation/

Using TSQL (you would need to know the registry key path off hand): https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-server-registry-transact-sql?view=sql-server-2017

SQL Server 2012+

Now, you can extract SQL Server Licensing information from the SQL Server Error Log, granted it may not be formatted the way you want, but the information is there and can be parsed, along with more descriptive information that you probably didn't expect.

EXEC sp_readerrorlog @p1 = 0
                    ,@p2 = 1
                    ,@p3 = N'licensing'

NOTE: I tried pasting the image directly, but since I am new at stakoverflow we have to follow the link below.

SQL Server License information via sp_readerrorlog

Created a stored procedure to list indexes for a table in database in SQL Server

create procedure _ListIndexes(@tableName nvarchar(200))
as
begin
/*
exec _ListIndexes '<YOUR TABLE NAME>'
*/
SELECT DB_NAME(DB_ID()) as DBName,SCH.name + '.' + TBL.name AS TableName,IDX.name as IndexName, IDX.type_desc AS IndexType,COL.Name as ColumnName,IC.*
    FROM sys.tables AS TBL 
         INNER JOIN sys.schemas AS SCH ON TBL.schema_id = SCH.schema_id 
         INNER JOIN sys.indexes AS IDX ON TBL.object_id = IDX.object_id 
         INNER JOIN sys.index_columns IC ON  IDX.object_id = IC.object_id and IDX.index_id = IC.index_id 
         INNER JOIN sys.columns COL ON ic.object_id = COL.object_id and IC.column_id = COL.column_id 
        where TBL.name = @tableName
    ORDER BY TableName,IDX.name

end

I solved in this way:

I created the 'ObjectControls' module for ThreeJS that allows you to rotate a single OBJECT (or a Group), and not the SCENE.

Include the libary:

<script src="ObjectControls.js"></script>

Usage:

var controls = new ObjectControls(camera, renderer.domElement, yourMesh);

You can find here a live demo here: https://albertopiras.github.io/threeJS-object-controls/

Here is the repo: https://github.com/albertopiras/threeJS-object-controls.

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

Going back to a really basic idea, we have 32 bits for our memory addresses. That works out to 2^32 unique combinations of addresses. By convention, each address points to 1 byte of data. Therefore, we can access up to a total 2^32 bytes of data.

In a 32 bit OS, each register stores 32 bits or 4 bytes. 32 bits (1 word) of information are processed per clock cycle. If you want to access a particular 1 byte, conceptually, we can "extract" the individual bytes (e.g. byte 0, byte 1, byte 2, byte 3 etc.) by doing bitwise logical operations.

E.g. to get "dddddddd", take "aaaaaaaabbbbbbbbccccccccdddddddd" and logical AND with "00000000000000000000000011111111".

If you are using HTML 5, there is the <audio> element.

On MDN:

The audio element is used to embed sound content in an HTML or XHTML document. The audio element was added as part of HTML5.

Update:

In order to play audio in the browser in HTML versions before 5 (including XHTML), you need to use one of the many flash audio players.

One nice surprise is for one who has git bash on his windows: just plain old linux wc -l <filename> will works for you there

You can install packages listed in a text file called requirements file. For example, if you have a file called req.txt containing the following text:

Django==1.4
South==0.7.3

and you issue at the command line:

pip install -r req.txt

pip will install packages listed in the file at the specific revisions.

Just to clarify some potential confusion. This only works when an element is present on DOM load:

$("#target").change(function(){
    //does some stuff;
});

When an element is dynamically loaded in later you can use:

$(".parent-element").on('change', '#target', function(){
   //does some stuff;
});

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

Yes. You'd use the urllib2 module, and encode using the multipart/form-data content type. Here is some sample code to get you started -- it's a bit more than just file uploading, but you should be able to read through it and see how it works:

user_agent = "image uploader"
default_message = "Image $current of $total"

I propose it remove the non printable characters like below instead of replacing it

private String removeNonBMPCharacters(final String input) {
    StringBuilder strBuilder = new StringBuilder();
    input.codePoints().forEach((i) -> {
        if (Character.isSupplementaryCodePoint(i)) {
            strBuilder.append("?");
        } else {
            strBuilder.append(Character.toChars(i));
        }
    });
    return strBuilder.toString();
}

import pygame, sys
from pygame.locals import *

def main():
    pygame.init()

    DISPLAY=pygame.display.set_mode((500,400),0,32)

    WHITE=(255,255,255)
    BLUE=(0,0,255)

    DISPLAY.fill(WHITE)

    pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50))

    while True:
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                sys.exit()
        pygame.display.update()

main()

This creates a simple window 500 pixels by 400 pixels that is white. Within the window will be a blue rectangle. You need to use the pygame.draw.rect to go about this, and you add the DISPLAY constant to add it to the screen, the variable blue to make it blue (blue is a tuple that values which equate to blue in the RGB values and it's coordinates.

For iTunes 12.9.5.5 and above you can install the apps by Copying the IPA file and Paste it (Cmd+V or Edit -> Paste in iTunes) in any categories as Music/Films/TV Programmes etc. The app will be installed automatically on your iPhone screen.

Tested on 29 Nov 2019.

Demo:

You can combine both in the same date function call

date("d-m-Y H:i:s");  

You can not drop the foreign key column because it is being referenced from the table assignmentStuff. So you should first drop the foreign key constraint assignmentStuff.assignmentIDX.

A similar question has already been asked here. Check also here for more info.

SQL Views:

View is a virtual table based on the result-set of an SQL statement and that is Stored in the database with some name.

SQL Table:

SQL table is database instance consists of fields (columns), and rows.

Check following post, author listed around seven differences between views and table

The accepted answer doesn't create a name-only attribute anymore (as of September 2017).

You should use JQuery prop() method to create name-only attributes.

$(body).prop('data-body', true)

I was struggling with this for a few days until I chanced on the issue when I had to build a new Dropdown. I had several DropDownList controls and attempted to get validation working with no luck. One was databound and the other was filled from the aspx page. I needed to drop the databound one and add a second manual list. In my case Validators failed if you built a dropdown like this and looked at any value (0 or -1) for either a required or compare validator:

<asp:DropDownList ID="DDL_Reason" CssClass="inputDropDown" runat="server">
<asp:ListItem>--Select--</asp:ListItem>                                                                                                
<asp:ListItem>Expired</asp:ListItem>                                                                                                
<asp:ListItem>Lost/Stolen</asp:ListItem>                                                                                                
<asp:ListItem>Location Change</asp:ListItem>                                                                                            
</asp:DropDownList>

However adding the InitialValue like this worked instantly for a compare Validator.

<asp:ListItem Text="-- Select --" Value="-1"></asp:ListItem>

I used this code -

Hide modal with smooth effect using Fade Out.

$('#myModal').fadeOut();

$('.modal-backdrop').fadeOut();

$('.modal-open').css({'overflow': 'visible'});

Ahhh, the stupid linesize ... Here is what I do in my profile.sql - works only on unixes:

echo SET LINES $(tput cols) > $HOME/.login_tmp.sql
@$HOME/.login_tmp.sql

if you find an equivalent for tput on Windows, it might work there as well

-l (that's a lower-case L).

Git revert only accepts commits

From the docs:

Given one or more existing commits, revert the changes that the related patches introduce ...

myFile is intepretted as a commit - because git revert doesn't accept file paths; only commits

Change one file to match a previous commit

To change one file to match a previous commit - use git checkout

git checkout HEAD~2 myFile

Use this:

alert($(".messageCheckbox").is(":checked").val())

This assumes the checkboxes to check have the class "messageCheckbox", otherwise you would have to do a check if the input is the checkbox type, etc.

Since image is deprecated, you should use varbinary.

per Microsoft (thanks for the link @Christopher)

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.

Every function you create has a property called prototype, and it starts off its life as an empty object. This property is of no use until you use this function as constructor function i.e. with the 'new' keyword.

This is often confused with the __proto__ property of an object. Some might get confused and except that the prototype property of an object might get them the proto of an object. But this is not case. prototype is used to get the __proto__ of an object created from a function constructor.

In the above example:

function Person(name){_x000D_
    this.name = name_x000D_
}; _x000D_
_x000D_
var eve = new Person("Eve");_x000D_
_x000D_
console.log(eve.__proto__ == Person.prototype) // true_x000D_
// this is exactly what prototype does, made Person.prototype equal to eve.__proto__

I hope it makes sense.

x = math.ceil(x * 100.0) / 100.0

Simply write a query like:

create table new_table as select * from old_table where 1=2;

where new_table is the name of the new table that you want to create and old_table is the name of the existing table whose structure you want to copy, this will copy only structure.

You should try something like this, I am doing this for my project, its a fallback system

//function to get the remote data
function url_get_contents ($url) {
    if (function_exists('curl_exec')){ 
        $conn = curl_init($url);
        curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($conn, CURLOPT_FRESH_CONNECT,  true);
        curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
        $url_get_contents_data = (curl_exec($conn));
        curl_close($conn);
    }elseif(function_exists('file_get_contents')){
        $url_get_contents_data = file_get_contents($url);
    }elseif(function_exists('fopen') && function_exists('stream_get_contents')){
        $handle = fopen ($url, "r");
        $url_get_contents_data = stream_get_contents($handle);
    }else{
        $url_get_contents_data = false;
    }
return $url_get_contents_data;
} 

then later you can do like this

$data = url_get_contents("http://www.google.com");
if($data){
//Do Something....
}

Here is a great example for using async in forEach loop.

Write your own asyncForEach

async function asyncForEach(array, callback) {  
    for (let index = 0; index < array.length; index++) {
        await callback(array[index], index, array)
    }
}

You can use it like this

await asyncForEach(array, async function(item,index,array){
     //await here
   }
)

In the res/drawable folder, put this:

progress.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
      android:pivotX="50%" 
      android:pivotY="50%" 
      android:fromDegrees="0"
      android:toDegrees="360">

    <shape 
        android:shape="ring" 
        android:innerRadiusRatio="3"
        android:thicknessRatio="8" 
        android:useLevel="false">

    <size 
        android:width="76dip" 
        android:height="76dip" />

    <gradient 
        android:type="sweep" 
        android:useLevel="false"
        android:startColor="#447a29" 
        android:endColor="#00ffffff"
        android:angle="0"/>

    </shape>

</rotate> 

Set startColor and endColor as per your choice .

Now set that progress.xml in ProgressBar's backgound .

Like this

<ProgressBar
  android:id="@+id/ProgressBar01" 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:indeterminateDrawable="@drawable/progress"
 />
