Your problem is on the call for the dialog

If you dont initialize the dialog, you don't have to pass "open" for it to show:

$("#dialog").dialog();

Also, this code needs to be on a $(document).ready(); function or be below the elements for it to work.

I am a beginner and may not clear syntax. To refer above information, I still not clear.

Both "arrA" & "arrB" can be accessed (print it out). However, can't get a size of "arrB".

What is a problem there?

1. Is 'char[]' incomplete type? or
2. 'sizeof' does not accept the extern variable/ label?

In my program, "arrA" & "arrB" are constant lists and fixed before to compile. I would like to use a label(let me easy to maintenance & save RAM memory).

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)

If you really need a list:

>>> list(string.ascii_lowercase)
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

And to do it with range

>>> list(map(chr, range(97, 123))) #or list(map(chr, range(ord('a'), ord('z')+1)))
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

If your WS-RS needs raise an error why not just use the WebApplicationException?

public MyEntity getFoo(@PathParam("id") long id,  @QueryParam("lang")long idLanguage) {

if (idLanguage== 0){
    // No URL parameter idLanguage was sent
    ResponseBuilder builder = Response.status(Response.Status.BAD_REQUEST);
    builder.entity("Missing idLanguage parameter on request");
    Response response = builder.build();
    throw new WebApplicationException(response);
    }
... //other stuff to return my entity
return myEntity;
}

It was probably discussed, but as of CSS3 there is nothing like what you need (see also "Is there a CSS selector for elements containing certain text?"). You will have to use additional markup, like this:

<li><span class="foo">some text</span></li>
<li>some other text</li>

Then refer to it the usual way:

li > span.foo {...}

mongod --dbpath [path_to_data_directory]

I generally assign the classpath to a variable and then verify it. I've written a small ruby script which I include in a my startup scripts which validates the classpath before launching java. Validating the classpath before the JVM starts has saved me lots of time troubleshooting these types of problems.

The Problem

There are a number of work-flows you can use. The main point is not to break history in a published branch unless you've communicated with everyone who might consume the branch and are willing to do surgery on everyone's clones. It's best not to do that if you can avoid it.

Solutions for Published Branches

Your outlined steps have merit. If you need the dev branch to be stable right away, do it that way. You have a number of tools for Debugging with Git that will help you find the right branch point, and then you can revert all the commits between your last stable commit and HEAD.

Either revert commits one at a time, in reverse order, or use the <first_bad_commit>..<last_bad_commit> range. Hashes are the simplest way to specify the commit range, but there are other notations. For example, if you've pushed 5 bad commits, you could revert them with:

# Revert a series using ancestor notation.
git revert --no-edit dev~5..dev

# Revert a series using commit hashes.
git revert --no-edit ffffffff..12345678

This will apply reversed patches to your working directory in sequence, working backwards towards your known-good commit. With the --no-edit flag, the changes to your working directory will be automatically committed after each reversed patch is applied.

See man 1 git-revert for more options, and man 7 gitrevisions for different ways to specify the commits to be reverted.

Alternatively, you can branch off your HEAD, fix things the way they need to be, and re-merge. Your build will be broken in the meantime, but this may make sense in some situations.

The Danger Zone

Of course, if you're absolutely sure that no one has pulled from the repository since your bad pushes, and if the remote is a bare repository, then you can do a non-fast-forward commit.

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

This will leave the reflog intact on your system and the upstream host, but your bad commits will disappear from the directly-accessible history and won't propagate on pulls. Your old changes will hang around until the repositories are pruned, but only Git ninjas will be able to see or recover the commits you made by mistake.

The accepted answer for this question is wrong, but I have low rep so can't add a comment to it.

The correct answer to this question is given by Mat:

shopt -s nullglob
logfiles=(*.log)
echo ${#logfiles[@]}

The problem with the accepted answer is that wc -l counts the number of newline characters, and counts them even if they print to the terminal as '?' in the output of 'ls -l'. This means that the accepted answer FAILS when a filename contains a newline character. I have tested the suggested command:

ls -l log* | wc -l

and it erroneously reports a value of 2 even if there is only 1 file matching the pattern whose name happens to contain a newline character. For example:

touch log$'\n'def
ls log* -l | wc -l

When everything sounded so complicated, this command worked for me:

keytool -genkey -alias foo -keystore cacerts -dname cn=test -storepass changeit -keypass changeit

When a developer is in trouble, I believe a simple working solution snippet is more than enough for him. Later he could diagnose the root cause and basic understanding related to the issue.

My solution

$.fn.textWidth = function(){
    var self = $(this),
        children = self.children(),
        calculator = $('<span style="display: inline-block;" />'),
        width;

    children.wrap(calculator);
    width = children.parent().width(); // parent = the calculator wrapper
    children.unwrap();
    return width;
};

The following code works for me on owl carousel .

https://github.com/OwlFonk/OwlCarousel

$(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    navigation: true,
    navigationText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

For OwlCarousel2

https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html

 $(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    nav: true,
    navText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

It exists now in the statsmodels package:

In your adapter class, in onBindViewHolder method, set ViewHolder to setIsRecyclable(false) as in below code.

@Override
public void onBindViewHolder(RecyclerViewAdapter.ViewHolder p1, int p2)
{
    // TODO: Implement this method
    p1.setIsRecyclable(false);

    // Then your other codes
}

It might be issue by proxy settings in server. You can try by disabling proxy setting,
<defaultProxy enabled="false" />

Here:

df = df.reset_index()
df.columns[0] = 'New_ID'
df['New_ID'] = df.index + 880

Try:

$result = curl_exec($cURL);
$result = json_decode($result,true);

Now you can access MessageID from $result['MessageID'].

As for the database, it's simply using a query like so:

INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');

Prepared.

You can use this:

select {
    width:100px; 
    overflow:hidden; 
    white-space:nowrap; 
    text-overflow:ellipsis;
}
select option {
    width:100px;
    text-overflow:ellipsis;
    overflow:hidden;
}
div {
    border-style:solid; 
    width:100px; 
    overflow:hidden; 
    white-space:nowrap; 
    text-overflow:ellipsis;
}

just to save my own deductions from all this is (for saving DBMS_OUTPUT output on the client, using sqlplus):

• no matter if i use Toad/with polling or sqlplus, for a long running script with occasional dbms_output.put_line commands, i will get the output in the end of the script execution
• set serveroutput on; and dbms_output.enable(); should be present in the script
• to save the output SPOOL command was not enough to get the DBMS_OUTPUT lines printed to a file - had to use the usual > windows CMD redirection. the passwords etc. can be given to the empty prompt, after invoking sqlplus. also the "/" directives and the "exit;" command should be put either inside the script, or given interactively as the password above (unless it is specified during the invocation of sqlplus)

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

Extending on what @vabhatia said, this is what you want in native JavaScript (without JQuery).

ParentNode.insertBefore(<your element>, ParentNode.firstChild);

You need the xml.etree.ElementTree.fromstring(text)

from xml.etree.ElementTree import XML, fromstring
myxml = fromstring(text)

No record matched means no record returned. There's no place for the "value" of 0 to go if no records are found. You could create a crazy UNION query to do what you want but much, much, much better simply to check the number of records in the result set.

There are several factors which means there is no binary answer. The question of what is best for performance depends on your environment. By the way, if your single select with an identifier is not sub-second, something may be wrong with your configuration.

The real question to ask is how do you want to access the data. Single selects support late-binding. For example if you only want employee information, you can select from the Employees table. The foreign key relationships can be used to retrieve related resources at a later time and as needed. The selects will already have a key to point to so they should be extremely fast, and you only have to retrieve what you need. Network latency must always be taken into account.

Joins will retrieve all of the data at once. If you are generating a report or populating a grid, this may be exactly what you want. Compiled and optomized joins are simply going to be faster than single selects in this scenario. Remember, Ad-hoc joins may not be as fast--you should compile them (into a stored proc). The speed answer depends on the execution plan, which details exactly what steps the DBMS takes to retrieve the data.

The simplest solution for this problem:

First make sure your sdk path is currect. Then Please close current project and in android startup menu click on import project and choose your project from explorer. This will always solve my problem

My solution was to make sure that all IIS features are installed. So went to add remove programs in the control panel and clicked on add remove windows features and selected all options except IIS 6 console compatibility.

It also works when accessoryType changed for cell

extension UITableViewCell{
    var selectedBackgroundColor: UIColor?{
        set{
            let customColorView = UIView()
            customColorView.backgroundColor = newValue
            selectedBackgroundView = customColorView
        }
        get{
            return selectedBackgroundView?.backgroundColor
        }
    }
}

And in UIViewController use like below...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! myCell
    cell.selectedBackgroundColor = UIColor.lightGray
    return cell
  }

First of all, login to your database and check whether the database table which you want to import is not available on your database.

If it is available, delete the table using the command. Else it will throw an error while importing the table.

DROP TABLE Table_Name;

Then, move to the folder in which you have the .sql file to import and run the following command from your terminal

mysql -u username -p  databasename  < yourtable.sql

The terminal will ask you to enter the password. Enter it and check the database.

This one is better, since it takes the globals and locals from the caller:

import sys
def execfile(filename, globals=None, locals=None):
    if globals is None:
        globals = sys._getframe(1).f_globals
    if locals is None:
        locals = sys._getframe(1).f_locals
    with open(filename, "r") as fh:
        exec(fh.read()+"\n", globals, locals)

If file is in use FileOutputStream fileOutputStream = new FileOutputStream(file); returns java.io.FileNotFoundException with 'The process cannot access the file because it is being used by another process' in the exception message.

If you're using ng-view in your Angular app you can listen for the $viewContentLoaded event and push a tracking event to Google Analytics.

Assuming you've set up your tracking code in your main index.html file with a name of var _gaq and MyCtrl is what you've defined in the ng-controller directive.

function MyCtrl($scope, $location, $window) {
  $scope.$on('$viewContentLoaded', function(event) {
    $window._gaq.push(['_trackPageView', $location.url()]);
  });
}

UPDATE: for new version of google-analytics use this one

function MyCtrl($scope, $location, $window) {
  $scope.$on('$viewContentLoaded', function(event) {
    $window.ga('send', 'pageview', { page: $location.url() });
  });
}

There is no command to do exactly what you asked.

Here are some close matches.

You can delete all the pods in a single namespace with this command:

kubectl delete --all pods --namespace=foo

You can also delete all deployments in namespace which will delete all pods attached with the deployments corresponding to the namespace

kubectl delete --all deployments --namespace=foo

You can delete all namespaces and every object in every namespace (but not un-namespaced objects, like nodes and some events) with this command:

kubectl delete --all namespaces

However, the latter command is probably not something you want to do, since it will delete things in the kube-system namespace, which will make your cluster not usable.

This command will delete all the namespaces except kube-system, which might be useful:

for each in $(kubectl get ns -o jsonpath="{.items[*].metadata.name}" | grep -v kube-system);
do
  kubectl delete ns $each
done

In Eclipse Ganymede (Subclipse)

Select project/file that contains bad change, and from pop-up menu choose:

Team -> Show History

Revisions related to that project/file will be shown in History tab.

Find revision where "bad changes" were committed and from pop-up menu choose:

Revert Changes from Revision X

This will merge changes in file(s) modified within bad revision, with revision prior to bad revision.

There are two scenarios from here:

1. If you committed no changes for that file (bad revision is last revision for that file), it will simply remove changes made in bad revision. Those changes are merged to your working copy so you have to commit them.

2. If you committed some changes for that file (bad revision is not last revision for that file), you will have to manually resolve conflict. Let say that you have file readme.txt with, and bad revision number is 33. Also, you've made another commit for that file in revision 34. After you choose Revert Changes from Revision 33 you will have following in your working copy:

readme.txt.merge-left.r33 - bad revision

readme.txt.merge-right.r32 - before bad revision

readme.txt.working - working copy version (same as in r34 if you don't have any uncommitted changes)

Original readme.txt will be marked conflicted, and will contain merged version (where changes from bad revision are removed) with some markers (<<<<<<< .working etc). If you just want to remove changes from bad revision and keep changes made after that, then all you have to do is remove markers. Otherwise, you can copy contents from one of 3 files mentioned above to original file. Whatever you choose, when you are done, mark conflict resolved by

Team - Mark Resolved

Temporary files will be removed and your file will be marked changed. As in 1, you have to commit changes.

Note that this does not remove revision from revision history in svn repository. You simply made new revision where changes from bad revision are removed.

$parent doesn't work if there are multiple parents. instead of that we can define a parent index variable in init and use it

<div data-ng-init="parentIndex = $index" ng-repeat="f in foos">
  <div>
    <div data-ng-init="childIndex = $index" ng-repeat="b in foos.bars">
      <a ng-click="addSomething(parentIndex)">Add Something</a>

If one does not know anything about the internal state of the given (Direct)ByteBuffer and wants to retrieve the whole content of the buffer, this can be used:

ByteBuffer byteBuffer = ...;
byte[] data = new byte[byteBuffer.capacity()];
((ByteBuffer) byteBuffer.duplicate().clear()).get(data);

replace:

input, select, textarea{
    color: #000;
}

with:

input, select, textarea{
    color: #f00;
}

or color: #ff0000;

There are 3 ways to do so :

1) Simply do SET DEFINE OFF; and then execute the insert stmt.

2) Simply by concatenating reserved word within single quotes and concatenating it. E.g. Select 'Java_22 ' || '& '|| ':' || ' Oracle_14' from dual --(:) is an optional.

3) By using CHR function along with concatenation. E.g. Select 'Java_22 ' || chr(38)||' Oracle_14' from dual

Well, since 'X' is a char and not an int, you cannot actually replace it in the matrix itself, however, the following code should print an 'x' char whenever it comes across a 1.

public void printGrid(int[][] in){  
    for(int i = 0; i < 20; i++){  
        for(int j = 0; j < 20; j++){  
            if(in[i][j] == 1)  
                System.out.print('X' + "\t");
            else
                System.out.print(in[i][j] + "\t");
        }
        System.out.print("\n");
    }
}

gradlew is a wrapper(w - character) that uses gradle.

Under the hood gradlew performs three main things:

• Download and install the correct gradle version
• Parse the arguments
• Call a gradle task

Using Gradle Wrapper we can distribute/share a project to everybody to use the same version and Gradle's functionality(compile, build, install...) even if it has not been installed.

To create a wrapper run:

gradle wrapper

This command generate:

gradle-wrapper.properties will contain the information about the Gradle distribution

*./ Is used on Unix to specify the current directory

I had this same problem. Make sure the app's migrations folder is created (YOURAPPNAME/ migrations). Delete the folder and enter the commands:

python manage.py migrate --fake
python manage.py makemigrations <app_name>
python manage.py migrate --fake-initial

I inserted this lines in each class in models.py:

class Meta:
    app_label = '<app_name>'

This solved my problem.

Try to get some debugging information, could be that the file path is wrong, for example.

Try these two things:- Add this line to the top of your sample page:

<?php error_reporting(E_ALL);?>

This will print all errors/warnings/notices in the page so if there is any problem you get a text message describing it instead of a blank page

Additionally you can change include() to require()

<?php require ('headings.php'); ?>
<?php require ('navbar.php'); ?>
<?php require ('image.php'); ?>

This will throw a FATAL error PHP is unable to load required pages, and should help you in getting better tracing what is going wrong..

You can post the error descriptions here, if you get any, and you are unable to figure out what it means..

I am using searchform.php and search.php files as already mentioned, but here I provide the actual code.

Creating a Search Page codex page helps here and #Creating_a_Search_Page_Template shows the search query.

In my case I pass the $search_query arguments to the WP_Query Class (which can determine if is search query!). I then run The Loop to display the post information I want to, which in my case is the the_permalink and the_title.

Search box form:

<form class="search" method="get" action="<?php echo home_url(); ?>" role="search">
  <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
  <button type="submit" role="button" class="btn btn-default right"/><span class="glyphicon glyphicon-search white"></span></button>
</form>

search.php template file:

<?php
    global $query_string;
    $query_args = explode("&", $query_string);
    $search_query = array();

    foreach($query_args as $key => $string) {
      $query_split = explode("=", $string);
      $search_query[$query_split[0]] = urldecode($query_split[1]);
    } // foreach

    $the_query = new WP_Query($search_query);
    if ( $the_query->have_posts() ) : 
    ?>
    <!-- the loop -->

    <ul>    
    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <li>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
        </li>   
    <?php endwhile; ?>
    </ul>
    <!-- end of the loop -->

    <?php wp_reset_postdata(); ?>

<?php else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

Microsoft converts your Int16 variables into Int32 when doing the add function.

Change the following:

Int16 answer = firstNo + secondNo;

into...

Int16 answer = (Int16)(firstNo + secondNo);

Here is one way to do this using css

HTML

<div class="imageWrapper">
    <img src="http://lorempixel.com/300/300/" alt="" />
    <a href="http://google.com" class="cornerLink">Link</a>
</div>?

CSS

.imageWrapper {
    position: relative;
    width: 300px;
    height: 300px;
}
.imageWrapper img {
    display: block;
}
.imageWrapper .cornerLink {
    opacity: 0;
    position: absolute;
    bottom: 0px;
    left: 0px;
    right: 0px;
    padding: 2px 0px;
    color: #ffffff;

You are off slightly on a few things here, so hopefully the following helps.

Firstly, you don't need to select ranges to access their properties, you can just specify their address etc. Secondly, unless you are manipulating the values within the range, you don't actually need to set them to a variant. If you do want to manipulate the values, you can leave out the bounds of the array as it will be set when you define the range.

It's also good practice to use Option Explicit at the top of your modules to force variable declaration.

The following will do what you are after:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = Range("C4:G4").Value
    Next
End Sub

If you do want to manipulate the values within the array then do this:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer
    Dim anARRAY as Variant

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       anARRAY= Range("C4:G4").Value

       'You can loop through the array and manipulate it here

       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = anARRAY
    Next
End Sub

It is actually called file:///android_asset/index.html

file:///android_assets/index.html will give you a build error.

If you want to trim specified number of spaces from left and right, you could do this:

def remove_outer_spaces(text, num_of_leading, num_of_trailing):
    text = list(text)
    for i in range(num_of_leading):
        if text[i] == " ":
            text[i] = ""
        else:
            break

    for i in range(1, num_of_trailing+1):
        if text[-i] == " ":
            text[-i] = ""
        else:
            break
    return ''.join(text)

txt1 = "   MY name is     "
print(remove_outer_spaces(txt1, 1, 1))  # result is: "  MY name is    "
print(remove_outer_spaces(txt1, 2, 3))  # result is: " MY name is  "
print(remove_outer_spaces(txt1, 6, 8))  # result is: "MY name is"

In Windows 2003 Server with "wincred"*, none of the other answers helped me. I had to use cmdkey.

• cmdkey /list lists all stored credentials.
• cmdkey /delete:Target deletes the credential with "Target" name.

(* By "wincred" I mean git config --global credential.helper wincred)

By definition, file: URLs are system-dependent, and they have little use. A URL as in your example works when used locally, i.e. the linking page itself is in the user’s computer. But browsers generally refuse to follow file: links on a page that it has fetched with the HTTP protocol, so that the page's own URL is an http: URL. When you click on such a link, nothing happens. The purpose is presumably security: to prevent a remote page from accessing files in the visitor’s computer. (I think this feature was first implemented in Mozilla, then copied to other browsers.)

So if you work with HTML documents in your computer, the file: URLs should work, though there are system-dependent issues in their syntax (how you write path names and file names in such a URL).

If you really need to work with an HTML document on your computers and another HTML document on a web server, the way to make links work is to use the local file as primary and, if needed, use client-side scripting to fetch the document from the server,

It says you don't have a local grunt so try:

npm install grunt

(without the -g it's a local grunt)

Though not directly related, make sure you have Gruntfile.js in your current folder.

Set Your Own application Path

Dim myPathsValues As String

    TextBox1.Text = Application.StartupPath
    TextBox2.Text = Len(Application.StartupPath)
    TextBox3.Text = Microsoft.VisualBasic.Right(Application.StartupPath, 10)
    myPathsValues = Val(TextBox2.Text) - 9
    TextBox4.Text = Microsoft.VisualBasic.Left(Application.StartupPath, myPathsValues) & "Reports"

Edit

Following solution could have problems with clustered indexes involved as mentioned here. Thanks to Martin for pointing this out.

The answer is kept to educate those (like me) who don't know all side-effects or ins and outs of SQL Server.

Expanding on the answer gaven by Quassnoi in your link, following works

DECLARE @Test TABLE (Number INTEGER, AText VARCHAR(2), ID INTEGER)
DECLARE @Number INT

INSERT INTO @Test VALUES (1, 'A', 1)
INSERT INTO @Test VALUES (2, 'B', 2)
INSERT INTO @Test VALUES (1, 'E', 5)
INSERT INTO @Test VALUES (3, 'C', 3)
INSERT INTO @Test VALUES (2, 'D', 4)

SET @Number = 0

;WITH q AS (
    SELECT  TOP 1000000 *
    FROM    @Test
    ORDER BY
            ID
)            
UPDATE  q
SET     @Number = Number = @Number + 1

Not sure that stretching a background image is possible. If you find that it's not possible, or not reliable in all of your target browsers, you could try using a stretched img tag with z-index set lower, and position set to absolute so that other content appears on top of it.

Let us know what you end up doing.

Edit: What I suggested is basically what's in gabriel's link. So try that :)

You can also plot the timestamp, value pairs using pyplot.plot (after parsing them from their string representation). (Tested with matplotlib versions 1.2.0 and 1.3.1.)

Example:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.plot(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Resulting image:

Here's the same as a scatter plot:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Produces an image similar to this:

Here is an actual working version of the above async foreach variants with sequential processing:

public static async Task ForEachAsync<T>(this List<T> enumerable, Action<T> action)
{
    foreach (var item in enumerable)
        await Task.Run(() => { action(item); }).ConfigureAwait(false);
}

Here is the implementation:

public async void SequentialAsync()
{
    var list = new List<Action>();

    Action action1 = () => {
        //do stuff 1
    };

    Action action2 = () => {
        //do stuff 2
    };

    list.Add(action1);
    list.Add(action2);

    await list.ForEachAsync();
}

What's the key difference? .ConfigureAwait(false); which keeps the context of main thread while async sequential processing of each task.

Instead of running perror on any error code you get, you can retrieve a complete listing of errno values on your system with the following one-liner:

cpp -dM /usr/include/errno.h | grep 'define E' | sort -n -k 3

Please place this in the head of your Page(s) if the "body" needs the use of 1 and the same font:

<style type="text/css">
body {font-family:FONT-NAME ;
     }
</style>

Everything between the tags <body> and </body>will have the same font

maybe you need to grant more permissions to your files.

suppose your code are under /var/www/my_project

try chmod -R 777 /var/www/my_project

You can get the value of selected radio button by Id using this in javascript/jQuery.

$("#InvCopyRadio:checked").val();

I hope this will help.

export is a built-in command of the bash shell and other Bourne shell variants. It is used to mark a shell variable for export to child processes.

lst = [4,6,12]

[sum(lst[:i+1]) for i in xrange(len(lst))]

If you are looking for a more efficient solution (bigger lists?) a generator could be a good call (or just use numpy if you really care about perf).

def gen(lst):
    acu = 0
    for num in lst:
        yield num + acu
        acu += num

print list(gen([4, 6, 12]))

Have a look at the start up scripts a Java heap size is set there, it looks like you're not setting this before running Spark worker.

# Set SPARK_MEM if it isn't already set since we also use it for this process
SPARK_MEM=${SPARK_MEM:-512m}
export SPARK_MEM

# Set JAVA_OPTS to be able to load native libraries and to set heap size
JAVA_OPTS="$OUR_JAVA_OPTS"
JAVA_OPTS="$JAVA_OPTS -Djava.library.path=$SPARK_LIBRARY_PATH"
JAVA_OPTS="$JAVA_OPTS -Xms$SPARK_MEM -Xmx$SPARK_MEM"

You can find the documentation to deploy scripts here.

The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)

OPTIONS /path

You can send an OPTIONS request with curl like this:

curl -i -X OPTIONS http://example.org/path

You may also use -v instead of -i to see more output.

OPTIONS *

To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:

curl -i --request-target "*" -X OPTIONS http://example.org

Summarizing other answers

Looking through the answers, we have seen a lot of back and forth, whether or not list comprehension or filter may be faster or if it is even important or pythonic to care about such an issue. In the end, the answer is as most times: it depends.

I just stumbled across this question while optimizing code where this exact question (albeit combined with an in expression, not ==) is very relevant - the filter + lambda expression is taking up a third of my computation time (of multiple minutes).

My case

In my case, the list comprehension is much faster (twice the speed). But I suspect that this varies strongly based on the filter expression as well as the Python interpreter used.

Test it for yourself

Here is a simple code snippet that should be easy to adapt. If you profile it (most IDEs can do that easily), you will be able to easily decide for your specific case which is the better option:

whitelist = set(range(0, 100000000, 27))

input_list = list(range(0, 100000000))

proximal_list = list(filter(
        lambda x: x in whitelist,
        input_list
    ))

proximal_list2 = [x for x in input_list if x in whitelist]

print(len(proximal_list))
print(len(proximal_list2))

If you do not have an IDE that lets you profile easily, try this instead (extracted from my codebase, so a bit more complicated). This code snippet will create a profile for you that you can easily visualize using e.g. snakeviz:

import cProfile
from time import time


class BlockProfile:
    def __init__(self, profile_path):
        self.profile_path = profile_path
        self.profiler = None
        self.start_time = None

    def __enter__(self):
        self.profiler = cProfile.Profile()
        self.start_time = time()
        self.profiler.enable()

    def __exit__(self, *args):
        self.profiler.disable()
        exec_time = int((time() - self.start_time) * 1000)
        self.profiler.dump_stats(self.profile_path)


whitelist = set(range(0, 100000000, 27))
input_list = list(range(0, 100000000))

with BlockProfile("/path/to/create/profile/in/profile.pstat"):
    proximal_list = list(filter(
            lambda x: x in whitelist,
            input_list
        ))

    proximal_list2 = [x for x in input_list if x in whitelist]

print(len(proximal_list))
print(len(proximal_list2))

Or like this

class Movie
{
  public string FilmName { get; set; }
  public string Genre { get; set; }
}

...

var listofGenres = new List<string> { "action", "comedy" };

var Movies = new List<Movie> {new Movie {Genre="action", FilmName="Film1"},
                new Movie {Genre="comedy", FilmName="Film2"},
                new Movie {Genre="comedy", FilmName="Film3"},
                new Movie {Genre="tragedy", FilmName="Film4"}};

var movies = Movies.Join(listofGenres, x => x.Genre, y => y, (x, y) => x).ToList();

Brendan is correct. You can edit the Select command to edit a filtered list of records. For instance "WHERE dept_no = 200".

A helpful step in tracking down this problem is to identify which bind-address MySQL is actually set to. You can do this with netstat:

netstat -nat |grep :3306

This helped me zero in on my problem, because there are multiple mysql config files, and I had edited the wrong one. Netstat showed mysql was still using the wrong config:

ubuntu@myhost:~$  netstat -nat |grep :3306
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN

So I grepped the config directories for any other files which might be overriding my setting and found:

ubuntu@myhost:~$  sudo grep -R bind /etc/mysql
/etc/mysql/mysql.conf.d/mysqld.cnf:bind-address         = 127.0.0.1
/etc/mysql/mysql.cnf:bind-address = 0.0.0.0
/etc/mysql/my.cnf:bind-address = 0.0.0.0

D'oh! This showed me the setting I had adjusted was the wrong config file, so I edited the RIGHT file this time, confirmed it with netstat, and was in business.

DISPLAY=:0 xclip -sel clip < ~/.ssh/id_rsa.pub didn't work for me (ubuntu 14.04), but you can use :

cat ~/.ssh/id_rsa.pub

to get your public key

Another alternative is to re-run the JRE setup. It typically installs a default JRE by placing java.exe, javaw.exe, etc. in your system folder. That would place the executables in your path, which should be sufficient, based on the note in the error message that it searched your path for javaw.exe

Edit. As noted in the comments, this is no longer working with the latest Android Studio releases.

The latest Android studio seems to only reference to "Offline mode" via the keymap, but toggling this does not seem to change anything anymore.

In Android Studio open the settings and search for offline it will find the Gradle category which contains Offline work. You can disable it there.

I used RCUNIT to do some unit testing for embedded code on PC before testing on the target. Good hardware interface abstraction is important else endianness and memory mapped registers are going to kill you.

This was best suited for all scenarios according to me:

<select ng-model="mySelection.value">
   <option ng-repeat="r in myList" value="{{r.Id}}" ng-selected="mySelection.value == r.Id">{{r.Name}}
   </option>
</select>

where you can use your model to bind the data. You will get the value as the object will contain and the default selection based on your scenario.

You can use Ansible stat module to register the file, and when module to apply the condition.

- name: Register file
      stat:
        path: "/tmp/test_file"
      register: file_path

- name: Create file if it doesn't exists
      file: 
        path: "/tmp/test_file"
        state: touch
      when: file_path.stat.exists == False

The reliable solution is catching the ObjectDisposedException.

The solution to write your overridden implementation of the Dispose method doesn't work, since there is a race condition between the thread calling Dispose method and the one accessing to the object: after having checked the hypothetic IsDisposed property , the object could be really disposed, throwing the exception all the same.

Another approach could be exposing a hypothetic event Disposed (like this), which is used to notify about the disposing object to every object interested, but this could be difficoult to plan depending on the software design.

The Java system property System.getProperty(...) to consult is "java.runtime.name". This will distinguish between "OpenJDK Runtime Environment" and "Java(TM) SE Runtime Environment". They both have the same vendor - "Oracle Corporation".

This property is also included in the output for java -version.

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

If the class is declared static, all of the members must be static too.

static NameValueCollection appSetting = ConfigurationManager.AppSettings;

Are you sure you want your employee class to be static? You almost certainly don't want that behaviour. You'd probably be better off removing the static constraint from the class and the members.

For completeness, the OP does not state he is looking to do this in a browser (if he is, as has been stated, it is generally not possible)

However javascript per se does allow this; it can be done with server side javascript.

\ is an escape character in Python. \t gets interpreted as a tab. If you need \ character in a string, you have to use \\.

Your code should be:
test_file=open('c:\\Python27\\test.txt','r')

An easier way to clear a screen while in python is to use Ctrl + L though it works for the shell as well as other programs.

This worked fine for me.

Step 1. Right click on database engine, click on activity monitor and see which process is having connection. Kill that particular user and execute the query Immediately.

Step 2.

and refresh the database.

You can try using the Wshshell.Run method which gives you little control of the process you start with it. Or you could use the WshShell.Exec method which will give you control to terminate it, get a response, pass more parameters (other than commandline args), get status, and others

To use Run (Simple Method)

Dim ProgramPath, WshShell, ProgramArgs, WaitOnReturn,intWindowStyle
Set WshShell=CreateObject ("WScript.Shell")
ProgramPath="c:\test run script.vbs"
ProgramArgs="/hello /world"
intWindowStyle=1
WaitOnReturn=True
WshShell.Run Chr (34) & ProgramPath & Chr (34) & Space (1) & ProgramArgs,intWindowStyle, WaitOnReturn

ProgramPath is the full path to your script you want to run
ProgramArgs is the arguments you want to pass to the script. (NOTE: the arguments are separated by a space, if you want to use an argument that contains a space then you will have to enclose that argument in quotes [Safe way to do this is use CHR (34) Example ProgramArgs= chr (34) & "/Hello World" & chr (34)])
IntWindowStyle is the integer that determines how the window will be displayed. More info on this and WaitOnReturn can be found here WshShell.Run Method
WaitOnReturn if true then the script will pause until the command has terminated, if false then the script will continue right after starting command.

NOTE: The Run method can return the exit code but you must set WaitOnReturn to True, and assign the 'WshShell.Run' to a variable. (EX: ExitCode=WshShell.Run (Command,intWindowStyle,True))

To Use EXEC (Advanced Method)

Dim ProgramPath, WshShell, ProgramArgs, Process, ScriptEngine
Set WshShell=CreateObject ("WScript.Shell")
ProgramPath="c:\test run script.vbs"
ProgramArgs="/hello /world"
ScriptEngine="CScript.exe"
Set Process=WshShell.Exec (ScriptEngine & space (1) & Chr(34) & ProgramPath & Chr (34) & Space (1) & ProgramArgs)
Do While Process.Status=0
    'Currently Waiting on the program to finish execution.
    WScript.Sleep 300
Loop

ProgramPath same as Run READ RUN'S DESCRIPTION
ProgramArgs DITTO
ScriptEngine The Engine you will be using for executing the script. since the exec method requires a win32 application, you need to specify this. Usually either "WScript.exe" or "CScript.exe". Note that in order to use stdin and stdout (we'll cover what these are a bit further down) you must choose "CScript.exe".
Process this is the Object that references to the program the script will start. It has several members and they are: ExitCode, ProcessID, Status, StdErr, StdIn, StdOut, Terminate.

More Details about the members of Process Object

1. ExitCode This is the exit code that is returned when the process terminates.
2. ProcessID This is the ID that is assigned to the process, every process has an unique processID.
3. Status This is a code number that indicates the status of the process, it get set to '-1' when the process terminates.
4. StdErr This is the object that represents the Standard Error Stream
5. StdIn This is the Object that represents the Standard Input Stream, use it to write additional parameters or anything you want to pass to the script you are calling. (Process.StdIn.WriteLine "Hello Other Worlds")
6. StdOut This is the Object that represents the Standard Output Stream, It is READONLY so you can use Process.StdOut.ReadLine. This is the stream that the called script will receive any information sent by the calling script's stdin. If you used the stdin's example then StdOut.Readline will return "Hello Other Worlds". If there is nothing to read then the script will hang while waiting for an output. meaning the script will appear to be Not Responding
   Note: you can use Read or ReadAll instead of ReadLine if you want. Use Read (X) if you want to read X amount of characters. Or ReadAll if you want the rest of the stream.
7. Terminate Call this method to force terminate the process.

1. Compile your application with -g, then you'll have debug symbols in the binary file.

2. Use gdb to open the gdb console.

3. Use file and pass it your application's binary file in the console.

4. Use run and pass in any arguments your application needs to start.

5. Do something to cause a Segmentation Fault.

6. Type bt in the gdb console to get a stack trace of the Segmentation Fault.

There are a few ways. One of the simplest is to create a my-paths.pth file (as described here). This is just a file with the extension .pth that you put into your system site-packages directory. On each line of the file you put one directory name, so you can put a line in there with /path/to/the/ and it will add that directory to the path.

You could also use the PYTHONPATH environment variable, which is like the system PATH variable but contains directories that will be added to sys.path. See the documentation.

Note that no matter what you do, sys.path contains directories not files. You can't "add a file to sys.path". You always add its directory and then you can import the file.

One way is to run the program in a subshell, and communicate with the subshell through a named pipe with the read command. This way you can check the exit status of the process being run and communicate this back through the pipe.

Here's an example of timing out the yes command after 3 seconds. It gets the PID of the process using pgrep (possibly only works on Linux). There is also some problem with using a pipe in that a process opening a pipe for read will hang until it is also opened for write, and vice versa. So to prevent the read command hanging, I've "wedged" open the pipe for read with a background subshell. (Another way to prevent a freeze to open the pipe read-write, i.e. read -t 5 <>finished.pipe - however, that also may not work except with Linux.)

rm -f finished.pipe
mkfifo finished.pipe

{ yes >/dev/null; echo finished >finished.pipe ; } &
SUBSHELL=$!

# Get command PID
while : ; do
    PID=$( pgrep -P $SUBSHELL yes )
    test "$PID" = "" || break
    sleep 1
done

# Open pipe for writing
{ exec 4>finished.pipe ; while : ; do sleep 1000; done } &  

read -t 3 FINISHED <finished.pipe

if [ "$FINISHED" = finished ] ; then
  echo 'Subprocess finished'
else
  echo 'Subprocess timed out'
  kill $PID
fi

rm finished.pipe

In Python you might be in for some surprises if you ask for forgiveness in this case.

try-except is not the right paradigm here.

If you accidentally get negative indices your in for a surprise.

Better solution is to provide the test function yourself:

def index_in_array(M, index):
    return index[0] >= 0 and index[1] >= 0 and index[0]< M.shape[0] and index[1] < M.shape[1]

Working with POST in webapi can be tricky! Would like to add to the already correct answer..

Will focus specifically on POST as dealing with GET is trivial. I don't think many would be searching around for resolving an issue with GET with webapis. Anyways..

If your question is - In MVC Web Api, how to- - Use custom action method names other than the generic HTTP verbs? - Perform multiple posts? - Post multiple simple types? - Post complex types via jQuery?

Then the following solutions may help:

First, to use Custom Action Methods in Web API, add a web api route as:

public static void Register(HttpConfiguration config)
{
    config.Routes.MapHttpRoute(
        name: "ActionApi",
        routeTemplate: "api/{controller}/{action}");
}

And then you may create action methods like:

[HttpPost]
public string TestMethod([FromBody]string value)
{
    return "Hello from http post web api controller: " + value;
}

Now, fire the following jQuery from your browser console

$.ajax({
    type: 'POST',
    url: 'http://localhost:33649/api/TestApi/TestMethod',
    data: {'':'hello'},
    contentType: 'application/x-www-form-urlencoded',
    dataType: 'json',
    success: function(data){ console.log(data) }
});

Second, to perform multiple posts, It is simple, create multiple action methods and decorate with the [HttpPost] attrib. Use the [ActionName("MyAction")] to assign custom names, etc. Will come to jQuery in the fourth point below

Third, First of all, posting multiple SIMPLE types in a single action is not possible. Moreover, there is a special format to post even a single simple type (apart from passing the parameter in the query string or REST style). This was the point that had me banging my head with Rest Clients (like Fiddler and Chrome's Advanced REST client extension) and hunting around the web for almost 5 hours when eventually, the following URL proved to be of help. Will quote the relevant content for the link might turn dead!

Content-Type: application/x-www-form-urlencoded
in the request header and add a = before the JSON statement:
={"Name":"Turbo Tina","Email":"[email protected]"}

PS: Noticed the peculiar syntax?

http://forums.asp.net/t/1883467.aspx?The+received+value+is+null+when+I+try+to+Post+to+my+Web+Api

Anyways, let us get over that story. Moving on:

Fourth, posting complex types via jQuery, ofcourse, $.ajax() is going to promptly come in the role:

Let us say the action method accepts a Person object which has an id and a name. So, from javascript:

var person = { PersonId:1, Name:"James" }
$.ajax({
    type: 'POST',
    url: 'http://mydomain/api/TestApi/TestMethod',
    data: JSON.stringify(person),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(data){ console.log(data) }
});

And the action will look like:

[HttpPost]
public string TestMethod(Person person)
{
    return "Hello from http post web api controller: " + person.Name;
}

All of the above, worked for me!! Cheers!

Try this

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    clearApplicationData();
}

public void clearApplicationData() {
    File cache = getCacheDir();
    File appDir = new File(cache.getParent());
    if (appDir.exists()) {
        String[] children = appDir.list();
        for (String s : children) {
            if (!s.equals("lib")) {
                deleteDir(new File(appDir, s));
                Log.i("EEEEEERRRRRROOOOOOORRRR", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
            }
        }
    }
}

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        int i = 0;
        while (i < children.length) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
            i++;
        }
    }

    assert dir != null;
    return dir.delete();
}

Don't forget about fragmentation. If you have a lot of traffic, your pools can be fragmented and even if you have several MB free, there could be no block larger than 4KB. Check size of largest free block with a query like:

 select

  10*trunc(KSMCHSIZ/10) "From",
  count(*) "Count" ,
  max(KSMCHSIZ) "Biggest",
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ<140
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 10*trunc(KSMCHSIZ/10)
UNION ALL
select
  '1 (140-267)' BUCKET,
  KSMCHCLS,
  KSMCHIDX,
  20*trunc(KSMCHSIZ/20) ,
  count(*) ,
  max(KSMCHSIZ) ,
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ between 140 and 267
and

I have tried it out successfully.

Use an extension method:

    public static List<string> ColumnList(this IDataReader dataReader)
    {
        var columns = new List<string>();
        for (int i = 0; i < dataReader.FieldCount; i++)
        {
            columns.Add(dataReader.GetName(i));
        }
        return columns;
    }

Here is a way to test if number is prime number.

function isPrime(numb){
  if (numb % 2 == 0) return false;
  for (var i=3; i<= Math.sqrt(numb); i = i + 2) {
    if (numb % i == 0) {
     return false;
    }
  }
  return true;
}

I used this solution, you have to define the height and width of your screen using MediaQuery:

 Container(
        height: MediaQuery.of(context).size.height,
        width: MediaQuery.of(context).size.width
  )

Yes, you're looking for the ReDim statement, which dynamically allocates the required amount of space in the array.

The following statement

Dim MyArray()

declares an array without dimensions, so the compiler doesn't know how big it is and can't store anything inside of it.

But you can use the ReDim statement to resize the array:

ReDim MyArray(0 To 3)

And if you need to resize the array while preserving its contents, you can use the Preserve keyword along with the ReDim statement:

ReDim Preserve MyArray(0 To 3)

But do note that both ReDim and particularly ReDim Preserve have a heavy performance cost. Try to avoid doing this over and over in a loop if at all possible; your users will thank you.

However, in the simple example shown in your question (if it's not just a throwaway sample), you don't need ReDim at all. Just declare the array with explicit dimensions:

Dim MyArray(0 To 3)

If you look at the alternatives on this page, of course the first option looks better and the second one is just more verbose. But if you are looking through a large class that someone else wrote, that verbosity can make the difference between realizing right away what the conditional is testing or not.

One of the reasons I moved away from Perl is because it relies so heavily on punctuation, which is much slower to interpret while reading.

I know I'm outvoted here, but I will almost always side with more explicit code so others can read it more accurately. Then again, I would never use a boolean variable called "status" either. Maybe isSuccess or just success, but "status" being true or false does not mean anything to the casual reader intuitively. As you can tell, I'm very into code readability because I read so much code others have written.

I may be late to the party but will have to add my own code for this. It uses approximately n/2 in space because we don't need to store even numbers and I also make use of the bitarray python module, further draStically cutting down on memory consumption and enabling computing all primes up to 1,000,000,000

from bitarray import bitarray
def primes_to(n):
    size = n//2
    sieve = bitarray(size)
    sieve.setall(1)
    limit = int(n**0.5)
    for i in range(1,limit):
        if sieve[i]:
            val = 2*i+1
            sieve[(i+i*val)::val] = 0
    return [2] + [2*i+1 for i, v in enumerate(sieve) if v and i > 0]

python -m timeit -n10 -s "import euler" "euler.primes_to(1000000000)"
10 loops, best of 3: 46.5 sec per loop

This was run on a 64bit 2.4GHZ MAC OSX 10.8.3

UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

So...

Produces...

Something that I didn't see mentioned in the other answers here is how you deal with unwinding when you don't know where the initial segue originated, which to me is an even more important use case. For example, say you have a help view controller (H) that you display modally from two different view controllers (A and B):

A ? H
B ? H

How do you set up the unwind segue so that you go back to the correct view controller? The answer is that you declare an unwind action in A and B with the same name, e.g.:

// put in AViewController.swift and BViewController.swift
@IBAction func unwindFromHelp(sender: UIStoryboardSegue) {
    // empty
}

This way, the unwind will find whichever view controller (A or B) initiated the segue and go back to it.

In other words, think of the unwind action as describing where the segue is coming from, rather than where it is going to.

This is the final solution.. its works for me...!!

1) Find the whale in your system tray, and right click

2) Go to settings > Reset

3) Reset to factory defaults

Say you want Comic Sans for the title and Helvetica for the x label.

csfont = {'fontname':'Comic Sans MS'}
hfont = {'fontname':'Helvetica'}

plt.title('title',**csfont)
plt.xlabel('xlabel', **hfont)
plt.show()

HTML Code

<input type="file" name="image" id="uploadImage" size="30" />
<input type="submit" name="upload"  class="send_upload" value="upload" />

jQuery Code using bind method

$(document).ready(function() {
    $('#upload').bind("click",function() 
    { if(!$('#uploadImage').val()){
                alert("empty");
                return false;} });  });

I think this way also a normal way. But sorry, I can't describe in English ((

This question has been pretty well answered, but I'm taking the liberty of adding a javascript solution. Just give the element that you want to 'expand' the id footerspacerdiv, and this javascript snippet will expand that div until the page takes up the full height of the browser window.

It works based on the observation that, when a page is less than the full height of the browser window, document.body.scrollHeight is equal to document.body.clientHeight. The while loop increases the height of footerspacerdiv until document.body.scrollHeight is greater than document.body.clientHeight. At this point, footerspacerdiv will actually be 1 pixel too tall, and the browser will show a vertical scroll bar. So, the last line of the script reduces the height of footerspacerdiv by one pixel to make the page height exactly the height of the browser window.

By placing footerspacerdiv just above the 'footer' of the page, this script can be used to 'push the footer down' to the bottom of the page, so that on short pages, the footer is flush with the bottom of the browser window.

<script>    
//expand footerspacer div so that footer goes to bottom of page on short pages        
  var objSpacerDiv=document.getElementById('footerspacer');          
  var bresize=0;   

  while(document.body.scrollHeight<=document.body.clientHeight) {
    objSpacerDiv.style.height=(objSpacerDiv.clientHeight+1)+"px";
    bresize=1;
  }             
  if(bresize) { objSpacerDiv.style.height=(objSpacerDiv.clientHeight-1)+"px"; }               
 </script>

None of these worked for me. I'm using Mac OS 10.10.5 and Workbench 6.3. What worked for me is Database->Migration Wizard... Flow the steps very carefully

Just use floatval().

E.g.:

$var = '122.34343';
$float_value_of_var = floatval($var);
echo $float_value_of_var; // 122.34343

And in case you wonder doubleval() is just an alias for floatval().

And as the other say, in a financial application, float values are critical as these are not precise enough. E.g. adding two floats could result in something like 12.30000000001 and this error could propagate.

If the request could not be correctly parsed (including the request entity/body) the appropriate response is 400 Bad Request [1].

RFC 4918 states that 422 Unprocessable Entity is applicable when the request entity is syntactically well-formed, but semantically erroneous. So if the request entity is garbled (like a bad email format) use 400; but if it just doesn't make sense (like @example.com) use 422.

If the issue is that, as stated in the question, user name/email already exists, you could use 409 Conflict [2] with a description of the conflict, and a hint about how to fix it (in this case, "pick a different user name/email"). However in the spec as written, 403 Forbidden [3] can also be used in this case, arguments about HTTP Authorization notwithstanding.

412 Precondition Failed [4] is used when a precondition request header (e.g. If-Match) that was supplied by the client evaluates to false. That is, the client requested something and supplied preconditions, knowing full well that those preconditions might fail. 412 should never be sprung on the client out of the blue, and shouldn't be related to the request entity per se.

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

You should really use Angular UI for that needs. Check it out: Angular UI Dialog

In a nutshell, with Angular UI dialog, you can pass variable from a controller to the dialog controller using resolve. Here's your "from" controller:

var d = $dialog.dialog({
  backdrop: true,
  keyboard: true,
  backdropClick: true,
  templateUrl:  '<url_of_your_template>',
  controller: 'MyDialogCtrl',
  // Interesting stuff here.
  resolve: {
    username: 'foo'
  }
});

d.open();

And in your dialog controller:

angular.module('mymodule')
  .controller('MyDialogCtrl', function ($scope, username) {
  // Here, username is 'foo'
  $scope.username = username;
}

EDIT: Since the new version of the ui-dialog, the resolve entry becomes:

resolve: { username: function () { return 'foo'; } }

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

Git doesn't store file permissions other than executable scripts. Consider using something like git-cache-meta to save file ownership and permissions.

Git can only store two types of modes: 755 (executable) and 644 (not executable). If your file was 444 git would store it has 644.

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

There is hurry.filesize that will take the size in bytes and make a nice string out if it.

>>> from hurry.filesize import size
>>> size(11000)
'10K'
>>> size(198283722)
'189M'

Or if you want 1K == 1000 (which is what most users assume):

>>> from hurry.filesize import size, si
>>> size(11000, system=si)
'11K'
>>> size(198283722, system=si)
'198M'

It has IEC support as well (but that wasn't documented):

>>> from hurry.filesize import size, iec
>>> size(11000, system=iec)
'10Ki'
>>> size(198283722, system=iec)
'189Mi'

Because it's written by the Awesome Martijn Faassen, the code is small, clear and extensible. Writing your own systems is dead easy.

Here is one:

mysystem = [
    (1024 ** 5, ' Megamanys'),
    (1024 ** 4, ' Lotses'),
    (1024 ** 3, ' Tons'), 
    (1024 ** 2, ' Heaps'), 
    (1024 ** 1, ' Bunches'),
    (1024 ** 0, ' Thingies'),
    ]

Used like so:

>>> from hurry.filesize import size
>>> size(11000, system=mysystem)
'10 Bunches'
>>> size(198283722, system=mysystem)
'189 Heaps'

it's well documented here:

https://cwiki.apache.org/confluence/display/TOMCAT/Connectors#Connectors-Q6

How do I bind to a specific ip address? - "Each Connector element allows an address property. See the HTTP Connector docs or the AJP Connector docs". And HTTP Connectors docs:

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html

Standard Implementation -> address

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."

If you want to use a dynamic filename filter you can implement FilenameFilter and pass in the constructor the dynamic name.

Of course this implies taht you must instantiate every time the class (overhead), but it works

Example:

public class DynamicFileNameFilter implements FilenameFilter {

    private String comparingname;

    public DynamicFileNameFilter(String comparingName){
        this.comparingname = comparingName;
    }

    @Override
    public boolean accept(File dir, String name) {
        File file = new File(name);

        if (name.equals(comparingname) && !file.isDirectory())
            return false;

        else
            return true;
    }

}

then you use where you need:

FilenameFilter fileNameFilter = new DynamicFileNameFilter("thedynamicNameorpatternYouAreSearchinfor");
File[] matchingFiles = dir.listFiles(fileNameFilter);

Most of the issues I've seen with developers complaining that Get Latest doesn't do what they expect stem from the fact that they're performing a Get Latest from Solution Explorer rather than from Source Control Explorer. Solution Explorer only gets the files that are part of the solution and ignores anything that may be required by files within the solution, and therefore part of source control, whereas Source Control explorer compares your local workspace against the repository on the server to determine which files are needed.

It's because you have:

def readTTable(fname):
    try:

without a matching except block after the try: block. Every try must have at least one matching except.

See the Errors and Exceptions section of the Python tutorial.

If you need to perform in Microsoft Windows the equivalent of a symlink to /dev/null in Linux you would open and administrator's cmd and type:

For files:

mklink c:\path\to\file.ext NUL:

Or, for directories:

mklink /D c:\path\to\dir NUL:

This will keep the file/direcotry always at 0 byte, and still return success to every write attempt.

Its depends on your locale system time settings, make 24 hours then it will show you 24 hours time.

You can use : org.springframework.util.StringUtils;

String stringDelimitedByComma = StringUtils.collectionToCommaDelimitedString(myList);

Op De Cirkel is mostly right. His suggestion will work in most cases:

myString.replaceAll("\\p{C}", "?");

But if myString might contain non-BMP codepoints then it's more complicated. \p{C} contains the surrogate codepoints of \p{Cs}. The replacement method above will corrupt non-BMP codepoints by sometimes replacing only half of the surrogate pair. It's possible this is a Java bug rather than intended behavior.

Using the other constituent categories is an option:

myString.replaceAll("[\\p{Cc}\\p{Cf}\\p{Co}\\p{Cn}]", "?");

However, solitary surrogate characters not part of a pair (each surrogate character has an assigned codepoint) will not be removed. A non-regex approach is the only way I know to properly handle \p{C}:

StringBuilder newString = new StringBuilder(myString.length());
for (int offset = 0; offset < myString.length();)
{
    int codePoint = myString.codePointAt(offset);
    offset += Character.charCount(codePoint);

    // Replace invisible control characters and unused code points
    switch (Character.getType(codePoint))
    {
        case Character.CONTROL:     // \p{Cc}
        case Character.FORMAT:      // \p{Cf}
        case Character.PRIVATE_USE: // \p{Co}
        case Character.SURROGATE:   // \p{Cs}
        case Character.UNASSIGNED:  // \p{Cn}
            newString.append('?');
            break;
        default:
            newString.append(Character.toChars(codePoint));
            break;
    }
}

There are actually three things here: origin master is two separate things, and origin/master is one thing. Three things total.

Two branches:

• master is a local branch
• origin/master is a remote branch (which is a local copy of the branch named "master" on the remote named "origin")

One remote:

• origin is a remote

Example: pull in two steps

Since origin/master is a branch, you can merge it. Here's a pull in two steps:

Step one, fetch master from the remote origin. The master branch on origin will be fetched and the local copy will be named origin/master.

git fetch origin master

Then you merge origin/master into master.

git merge origin/master

Then you can push your new changes in master back to origin:

git push origin master

More examples

You can fetch multiple branches by name...

git fetch origin master stable oldstable

You can merge multiple branches...

git merge origin/master hotfix-2275 hotfix-2276 hotfix-2290

In an attempt to find a way to make the target cell for the intersect method a name table array, I stumbled across a simple way to run something when ANY cell or set of cells on a particular sheet changes. This code is placed in the worksheet module as well:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 0 Then
'mycode here

I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding

style="position: relative; bottom: 0px"

to your Widget2 tag. Also try:

style="position: absolute; bottom: 0px"

if you want to snap your widget to the bottom of the screen.

I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.

SELECT * 
FROM Member
WHERE DATEPART(m, date_created) = DATEPART(m, DATEADD(m, -1, getdate()))
AND DATEPART(yyyy, date_created) = DATEPART(yyyy, DATEADD(m, -1, getdate()))

You need to check the month and year.

Somewhat dated question, but maybe still useful: you may take a look at FusionCache ?, which I recently released.

The feature you are looking for is described here, and you can use it like this:

const string CacheKey = "CacheKey";
static string GetCachedData()
{
    return fusionCache.GetOrSet(
        CacheKey,
        _ => SomeHeavyAndExpensiveCalculation(),
        TimeSpan.FromMinutes(20)
    );
}

You may also find some of the other features interesting like fail-safe, advanced timeouts with background factory completion and support for an optional, distributed 2nd level cache.

If you will give it a chance please let me know what you think.

java.util.Stack inherits the synchronization overhead of java.util.Vector, which is usually not justified.

It inherits a lot more than that, though. The fact that java.util.Stack extends java.util.Vector is a mistake in object-oriented design. Purists will note that it also offers a lot of methods beyond the operations traditionally associated with a stack (namely: push, pop, peek, size). It's also possible to do search, elementAt, setElementAt, remove, and many other random-access operations. It's basically up to the user to refrain from using the non-stack operations of Stack.

For these performance and OOP design reasons, the JavaDoc for java.util.Stack recommends ArrayDeque as the natural replacement. (A deque is more than a stack, but at least it's restricted to manipulating the two ends, rather than offering random access to everything.)

Something like this works fine for me:

public partial class Form1 : Form
{
    Form mainFormHandler;
...
}

private void Form1_Load(object sender, EventArgs e){
    mainFormHandler = Application.OpenForms[0];
   //or instead use this one:
   //mainFormHandler = Application.OpenForms["Form1"];
}

Then you can change the size as below:

mainFormHandler.Width = 600;
mainFormHandler.Height= 400;

or

mainFormHandler.Size = new Size(600, 400);

Another useful point is that if you want to change the size of mainForm from another Form, you can simply use Property to set the size.

I've been using something like this. Just set up a simple HTML page with an textinput. Make sure that the textinput always has focus. When you scan a barcode with your barcode scanner you will receive the code and after that a 'enter'. Realy simple then; just capture the incoming keystrokes and when the 'enter' comes in you can use AJAX to handle your code.

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

I made this simple tool to take the place of hosts. Regular expressions are supported. https://github.com/stackia/DNSAgent

A sample configuration:

[
    {
        "Pattern": "^.*$",
        "NameServer": "8.8.8.8"
    },
    {
        "Pattern": "^(.*\\.googlevideo\\.com)|((.*\\.)?(youtube|ytimg)\\.com)$",
        "Address": "203.66.168.119"
    },
    {
        "Pattern": "^.*\\.cn$",
        "NameServer": "114.114.114.114"
    },
    {
        "Pattern": "baidu.com$",
        "Address": "127.0.0.1"
    }
]

If you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Otherwise,

var scrollTop = function() {
    window.scrollTo(0, 0);
};

should do the trick.

If you really want to avoid putting something with a name (either an iteration variable as in the OP, or unwanted list or unwanted generator returning true the wanted amount of time) you could do it if you really wanted:

for type('', (), {}).x in range(somenumber):
    dosomething()

The trick that's used is to create an anonymous class type('', (), {}) which results in a class with empty name, but NB that it is not inserted in the local or global namespace (even if a nonempty name was supplied). Then you use a member of that class as iteration variable which is unreachable since the class it's a member of is unreachable.

I think what you're of doing here is using a structure containing your class instances. I don't know the syntax for naming structures in python, but in perl I could create a structure obj.id[x] where x is an incremented integer. Then, I could just refer back to the specific class instance I needed by referencing the struct numerically. Is this anything in the direction of what you're trying to do?

:: is the scope resolution operator. It's used to specify the scope of something.

For example, :: alone is the global scope, outside all other namespaces.

some::thing can be interpreted in any of the following ways:

• some is a namespace (in the global scope, or an outer scope than the current one) and thing is a type, a function, an object or a nested namespace;
• some is a class available in the current scope and thing is a member object, function or type of the some class;
• in a class member function, some can be a base type of the current type (or the current type itself) and thing is then one member of this class, a type, function or object.

You can also have nested scope, as in some::thing::bad. Here each name could be a type, an object or a namespace. In addition, the last one, bad, could also be a function. The others could not, since functions can't expose anything within their internal scope.

So, back to your example, ::thing can be only something in the global scope: a type, a function, an object or a namespace.

The way you use it suggests (used in a pointer declaration) that it's a type in the global scope.

I hope this answer is complete and correct enough to help you understand scope resolution.

When people talk about HTML5 applications they're most likely talking about writing just a simple web page or embedding a web page into their app (which will essentially provide the user interface). For the later there are different frameworks available, e.g. PhoneGap. These are used to provide more than the default browser features (e.g. multi touch) as well as allowing the app to run seamingly "standalone" and without the browser's navigation bars etc.

Adding solution for CentOs 7 (python 3.6.x)

yum install python36-tkinter

I had tried about every version possible, hopefully this helps out others.

Use this annotation

@RequestMapping(value = "/url", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON})

You should try this. I guess it will work.

There is no portable way to read raw characters from a Java console.

Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.

>>> import re
>>> string1 = "498results should get"
>>> int(re.search(r'\d+', string1).group())
498

If there are multiple integers in the string:

>>> map(int, re.findall(r'\d+', string1))
[498]

Solutions described here work, but I want to add that you need to have correct target selected on the top left corner of Build Settings in Xcode. Lost some time figuring this out...

Gestures are those subtle motions to trigger interactions between the touch screen and the user. It lasts for the time between the first touch on the screen to the point when the last finger leaves the surface.

Android provides us with a class called GestureDetector using which we can detect common gestures like tapping down and up, swiping vertically and horizontally (fling), long and short press, double taps, etc. and attach listeners to them.

Make our Activity class implement GestureDetector.OnDoubleTapListener (for double tap gesture detection) and GestureDetector.OnGestureListener interfaces and implement all the abstract methods.For more info. you may visit https://developer.android.com/training/gestures/detector.html . Courtesy

Use JQuery. You need to set-up a click event on your button which will toggle the visibility of your wizard div.

$('#btn').click(function() {
    $('#wizard').toggle();
});

Refer to the JQuery website for more information.

This can also be done without JQuery. Using only standard JavaScript:

<script type="text/javascript">
   function toggle_visibility(id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';
   }
</script>

Then add onclick="toggle_visibility('id_of_element_to_toggle');" to the button that is used to show and hide the div.

I had this issue when I was trying to make my Docker container smaller. It was because I'd installed Python 2.7 with:

apt-get install -y --no-install-recommends python

And I should not have included the --no-install-recommends flag:

apt-get install -y python

I had trouble changing the text color as well - I never saw the color change.

Until I added the code to change the text color to the event DataBindingsComplete for DataGridView. After that it worked.

I hope this will help people who face the same problem.

I know this thread is old.... but I faced the same problem... If you are willing to use thread.join()

import threading

class test:

    def __init__(self):
        self.msg=""

    def hello(self,bar):
        print('hello {}'.format(bar))
        self.msg="foo"


    def main(self):
        thread = threading.Thread(target=self.hello, args=('world!',))
        thread.start()
        thread.join()
        print(self.msg)

g=test()
g.main()

Might not be the case, but this was the solution to my "pre-receive hook declined" error:

There are some repositories that only allow modifications through Pull Request. This means that you have to

1. Create a new branch taking as base the branch that you want to push your changes to.
2. Commit and push your changes to the new branch.
3. Open a Pull Request to merge your branch with the original one.

As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.

So, writing (in SLF4J version 1.7.x and later)

 logger.error("one two three: {} {} {}", "a", "b", 
              "c", new Exception("something went wrong"));

or writing (in SLF4J version 1.6.x)

 logger.error("one two three: {} {} {}", new Object[] {"a", "b", 
              "c", new Exception("something went wrong")});

will yield

one two three: a b c
java.lang.Exception: something went wrong
    at Example.main(Example.java:13)
    at java.lang.reflect.Method.invoke(Method.java:597)
    at ...

The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.

• You use String when an immutable structure is appropriate; obtaining a new character sequence from a String may carry an unacceptable performance penalty, either in CPU time or memory (obtaining substrings is CPU efficient because the data is not copied, but this means a potentially much larger amount of data may remain allocated).
• You use StringBuilder when you need to create a mutable character sequence, usually to concatenate several character sequences together.
• You use StringBuffer in the same circumstances you would use StringBuilder, but when changes to the underlying string must be synchronized (because several threads are reading/modifyind the string buffer).

See an example here.

First rule of threading - "Threading is fun"...

I'm not able to understand the flow of execution of the program, And when ob1 is created then the constructor is called where t.start() is written but still run() method is not executed rather main() method continues execution. So why is this happening?

This is exactly what should happen. When you call Thread#start, the thread is created and schedule for execution, it might happen immediately (or close enough to it), it might not. It comes down to the thread scheduler.

This comes down to how the thread execution is scheduled and what else is going on in the system. Typically, each thread will be given a small amount of time to execute before it is put back to "sleep" and another thread is allowed to execute (obviously in multiple processor environments, more than one thread can be running at time, but let's try and keep it simple ;))

Threads may also yield execution, allow other threads in the system to have chance to execute.

You could try

NewThread(String threadname) {
    name = threadname;
    t = new Thread(this, name);
    System.out.println("New thread: " + t);
    t.start(); // Start the thread
    // Yield here
    Thread.yield();
}

And it might make a difference to the way the threads run...equally, you could sleep for a small period of time, but this could cause your thread to be overlooked for execution for a period of cycles (sometimes you want this, sometimes you don't)...

join() method is used to wait until the thread on which it is called does not terminates, but here in output we see alternate outputs of the thread why??

The way you've stated the question is wrong...join will wait for the Thread it is called on to die before returning. For example, if you depending on the result of a Thread, you could use join to know when the Thread has ended before trying to retrieve it's result.

Equally, you could poll the thread, but this will eat CPU cycles that could be better used by the Thread instead...

This method restores sys.stdout even if there's an exception. It also gets any output before the exception.

I realize this is years late, but I thought I could expand on Conor's answer and add a little bit more to the discussion.

Can someone give me a step by step description of how cookie based authentication works? I've never done anything involving either authentication or cookies. What does the browser need to do? What does the server need to do? In what order? How do we keep things secure?

Step 1: Client > Signing up

Before anything else, the user has to sign up. The client posts a HTTP request to the server containing his/her username and password.

Step 2: Server > Handling sign up

The server receives this request and hashes the password before storing the username and password in your database. This way, if someone gains access to your database they won't see your users' actual passwords.

Step 3: Client > User login

Now your user logs in. He/she provides their username/password and again, this is posted as a HTTP request to the server.

Step 4: Server > Validating login

The server looks up the username in the database, hashes the supplied login password, and compares it to the previously hashed password in the database. If it doesn't check out, we may deny them access by sending a 401 status code and ending the request.

Step 5: Server > Generating access token

If everything checks out, we're going to create an access token, which uniquely identifies the user's session. Still in the server, we do two things with the access token:

1. Store it in the database associated with that user
2. Attach it to a response cookie to be returned to the client. Be sure to set an expiration date/time to limit the user's session

Henceforth, the cookies will be attached to every request (and response) made between the client and server.

Step 6: Client > Making page requests

Back on the client side, we are now logged in. Every time the client makes a request for a page that requires authorization (i.e. they need to be logged in), the server obtains the access token from the cookie and checks it against the one in the database associated with that user. If it checks out, access is granted.

This should get you started. Be sure to clear the cookies upon logout!

Check out the aq branch, and rebase from master.

git checkout aq
git rebase master

Here it is. Add this code to your web.config file:

<system.webServer>
    <rewrite>
        <rules>
            <rule name="Root Hit Redirect" stopProcessing="true">
                <match url="^$" />
                <action type="Redirect" url="/menu_1/MainScreen.aspx" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

It will do 301 Permanent Redirect (URL will be changed in browser). If you want to have such "redirect" to be invisible (rewrite, internal redirect), then use this rule (the only difference is that "Redirect" has been replaced by "Rewrite"):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="Root Hit Redirect" stopProcessing="true">
                <match url="^$" />
                <action type="Rewrite" url="/menu_1/MainScreen.aspx" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

I wrote this awhile back. It assumes the delimiter is a comma and that the individual values aren't bigger than 127 characters. It could be modified pretty easily.

It has the benefit of not being limited to 4,000 characters.

Good luck!

Such error happens when,

1. You misspell module name which you injected.
2. If you missed to include js file of that module.

Sometimes people write js file name instead of the module name which we are injecting.

In these cases what happens is angular tries to look for the module provided in the square bracket []. If it doesn't find the module, it throws error.

Best I got so far:

dynamic DynamicCast(object entity, Type to)
{
    var openCast = this.GetType().GetMethod("Cast", BindingFlags.Static | BindingFlags.NonPublic);
    var closeCast = openCast.MakeGenericMethod(to);
    return closeCast.Invoke(entity, new[] { entity });
}
static T Cast<T>(object entity) where T : class
{
    return entity as T;
}

If you don't want to actually navigate to a new page you can also have your anchor somewhere on the page like this.

<a id="the_anchor" href="">

And then to assign your string of JavaScript to the the onclick of the anchor, put this somewhere else (i.e. the header, later in the body, whatever):

<script>
    var js = "alert('I am your string of JavaScript');"; // js is your string of script
    document.getElementById('the_anchor').href = 'javascript:' + js;
</script>

If you have all of this info on the server before sending out the page, then you could also simply place the JavaScript directly in the href attribute of the anchor like so:

<a href="javascript:alert('I am your script.'); alert('So am I.');">Click me</a>

My solution was to run

mysql_upgrade -u root

Scenario: I updated the MySQL version on my Mac with 'homebrew upgrade'. Afterwards, some stuff worked, but other commands raised the error described in the question.

Use the modulus operator %, it returns the remainder.

int a = 5;
int b = 3;

if (a % b != 0) {
   printf("The remainder is: %i", a%b);
}

To quote the Christmas analogy again:

In SQL, NULL basically means "closed box" (unknown). So, the result of comparing two closed boxes will also be unknown (null).

I understand, for a developer, this is counter-intuitive, because in programming languages, often NULL rather means "empty box" (known). And comparing two empty boxes will naturally yield true / equal.

This is why JavaScript for example distinguishes between null and undefined.

If you're using getline after cin >> something, you need to flush the newline out of the buffer in between.

My personal favourite for this if no characters past the newline are needed is cin.sync(). However, it is implementation defined, so it might not work the same way as it does for me. For something solid, use cin.ignore(). Or make use of std::ws to remove leading whitespace if desirable:

int a;

cin >> a;
cin.ignore (std::numeric_limits<std::streamsize>::max(), '\n'); 
//discard characters until newline is found

//my method: cin.sync(); //discard unread characters

string s;
getline (cin, s); //newline is gone, so this executes

//other method: getline(cin >> ws, s); //remove all leading whitespace

$eval and $parse don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.

Q: What exactly is $eval doing? Why does it need its own mini parsing language?

From the docs:

Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.

It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).

Q: Why isn't plain old javascript "eval" being used?

Because it's not actually evaluating JavaScript. As the docs say:

If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.

The docs linked to above have a lot more information.

To convert an integer to a string also involves char array or memory management.

To handle that part for such short arrays, code could use a compound literal, since C99, to create array space, on the fly. The string is valid until the end of the block.

#define UNS_HEX_STR_SIZE ((sizeof (unsigned)*CHAR_BIT + 3)/4 + 1)
//                         compound literal v--------------------------v
#define U2HS(x) unsigned_to_hex_string((x), (char[UNS_HEX_STR_SIZE]) {0}, UNS_HEX_STR_SIZE)

char *unsigned_to_hex_string(unsigned x, char *dest, size_t size) {
  snprintf(dest, size, "%X", x);
  return dest;
}

int main(void) {
  // 3 array are formed v               v        v
  printf("%s %s %s\n", U2HS(UINT_MAX), U2HS(0), U2HS(0x12345678));
  char *hs = U2HS(rand());
  puts(hs);
  // `hs` is valid until the end of the block
}

Output

FFFFFFFF 0 12345678

This Solution works for me:

    <meta property="og:title" content="Testing Title" />
    <meta
      property="og:description"
      content="This is best way to view your Time Table & Join Meetings"
    />
    <meta
      property="og:image"
      itemprop="image"
      content="//upload.wikimedia.org/wikipedia/commons/d/d4/JPEG_example_image_decompressed.jpg"
    />
    <meta property="og:url" content="https://google.com/" />
    <meta property="og:type" content="website" />
    <meta property="og:image:type" content="image/jpeg" />

tested on codesandbox.io

here's the link: https://l8ogr.csb.app/

one silly little thing did that magic, by removing "http" or "https" from the Image Url

if your image URL is ex: https://test.com/img.jpeg to //test.com/img.jpeg

<meta property="og:image" itemprop="image" content="//test.com/img.jpg"/>

To check whether a property exists on a JObject, you can use the square bracket syntax and see whether the result is null or not. If the property exists, a JToken will be always be returned (even if it has the value null in the JSON).

JToken token = jObject["param"];
if (token != null)
{
    // the "param" property exists
}

If you have a JToken in hand and you want to see if it is non-empty, well, that depends on what type of JToken it is and how you define "empty". I usually use an extension method like this:

public static class JsonExtensions
{
    public static bool IsNullOrEmpty(this JToken token)
    {
        return (token == null) ||
               (token.Type == JTokenType.Array && !token.HasValues) ||
               (token.Type == JTokenType.Object && !token.HasValues) ||
               (token.Type == JTokenType.String && token.ToString() == String.Empty) ||
               (token.Type == JTokenType.Null);
    }
}

or use this syntax:

$("#mainTable").css("width", "100px");
$("#mainTable").css("height", "200px");

All of your Laravel files should be in one location. Laravel is exposing its public folder to server. That folder represents some kind of front-controller to whole application. Depending on you server configuration, you have to point your server path to that folder. As I can see there is www site on your picture. www is default root directory on Unix/Linux machines. It is best to take a look inside you server configuration and search for root directory location. As you can see, Laravel has already file called .htaccess, with some ready Apache configuration.

Here this should help you

The below jsfiddle link will help you understand how to rotate a image.I used the same one to rotate the dial of a clock.

http://jsfiddle.net/xw89p/

var rotation = function (){
   $("#image").rotate({
      angle:0, 
      animateTo:360, 
      callback: rotation,
      easing: function (x,t,b,c,d){       
          return c*(t/d)+b;
      }
   });
}
rotation();

Where: • t: current time,

• b: begInnIng value,

• c: change In value,

• d: duration,

• x: unused

No easing (linear easing): function(x, t, b, c, d) { return b+(t/d)*c ; }

For me the problem was that I was passing Activity to the constructor, not Context

public Adapter(Activity activity, List<MediaItem> items, boolean can) {
    mItems = items;
    canEdit = can;
    mActivity = activity;
}

and using this activity to getDefaultSharedPreferences(), so I changed the Activity to Context and I was still calling the Adapter constructor with MainActivity.this

Try to find .npmrc in C:\Users\.npmrc

then open (notepad), write, and save inside :

proxy=http://<username>:<pass>@<proxyhost>:<port>

PS : remove "<" and ">" please !!

Not committed yet?

It is a orphan branch if it has no commit.

No siblings solution:

var x = $('#xxx').parent().html();
alert(x);

Universal solution:

// no cloning necessary    
var x = $('#xxx').wrapAll('<div>').parent().html(); 
alert(x);

I think what you're trying to do is:

-(void) score2 {
    [self score];
}

The [object message] syntax is the normal way to call a method in objective-c. I think the @selector syntax is used when the method to be called needs to be determined at run-time, but I don't know objective-c well enough to give you more information on that.
