Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.

Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.

The big difference is perfectly explained here.

Basically, lightweight tags are just pointers to specific commits. No further information is saved; on the other hand, annotated tags are regular objects, which have an author and a date and can be referred because they have their own SHA key.

If knowing who tagged what and when is relevant for you, then use annotated tags. If you just want to tag a specific point in your development, no matter who and when did that, then lightweight tags are good enough.

Normally you'd go for annotated tags, but it is really up to the Git master of the project.

git push --tags production

CAREFUL: In the command in Lawakush Kurmi's answer (git tag -a v1.0) the -a flag is used. This flag tells Git to create an annotated flag. If you don't provide the flag (i.e. git tag v1.0) then it'll create what's called a lightweight tag.

Annotated tags are recommended, because they include a lot of extra information such as:

• the person who made the tag
• the date the tag was made
• a message for the tag

Because of this, you should always use annotated tags.

Clone the repository as normal:

git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle

Then checkout the tag you want like so:

git checkout tags/1.1.4

This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".

To retain any changes made, move them to a new branch:

git checkout -b 1.1.4-jspooner

You can get back to the master branch by using:

git checkout master

Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:

git checkout 1.1.4

But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:

warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'

The shorthand can be safely used if the repository does not share names between branches and tags.

Looks like recentish versions of Git (I'm on git v2.20) allow one to simply say

git fetch --prune --prune-tags

Much cleaner!

https://git-scm.com/docs/git-fetch#_pruning

You can also configure git to always prune tags when fetching:

git config fetch.pruneTags true

If you only want to prune tags when fetching from a specific remote, you can use the remote.<remote>.pruneTags option. For example, to always prune tags when fetching from origin but not other remotes,

git config remote.origin.pruneTags true

Example:

git tag -a v1.2 9fceb02 -m "Message here"

Where 9fceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.2.

You can do git log to show all the commit id's in your current branch.

There is also a good chapter on tagging in the Pro Git book.

Warning: This creates tags with the current date (and that value is what will show on a GitHub releases page, for example). If you want the tag to be dated with the commit date, please look at another answer.

(This answer took a while to write, and codeWizard's answer is correct in aim and essence, but not entirely complete, so I'll post this anyway.)

There is no such thing as a "remote Git tag". There are only "tags". I point all this out not to be pedantic,¹ but because there is a great deal of confusion about this with casual Git users, and the Git documentation is not very helpful² to beginners. (It's not clear if the confusion comes because of poor documentation, or the poor documentation comes because this is inherently somewhat confusing, or what.)

There are "remote branches", more properly called "remote-tracking branches", but it's worth noting that these are actually local entities. There are no remote tags, though (unless you (re)invent them). There are only local tags, so you need to get the tag locally in order to use it.

The general form for names for specific commits—which Git calls references—is any string starting with refs/. A string that starts with refs/heads/ names a branch; a string starting with refs/remotes/ names a remote-tracking branch; and a string starting with refs/tags/ names a tag. The name refs/stash is the stash reference (as used by git stash; note the lack of a trailing slash).

There are some unusual special-case names that do not begin with refs/: HEAD, ORIG_HEAD, MERGE_HEAD, and CHERRY_PICK_HEAD in particular are all also names that may refer to specific commits (though HEAD normally contains the name of a branch, i.e., contains ref: refs/heads/branch). But in general, references start with refs/.

One thing Git does to make this confusing is that it allows you to omit the refs/, and often the word after refs/. For instance, you can omit refs/heads/ or refs/tags/ when referring to a local branch or tag—and in fact you must omit refs/heads/ when checking out a local branch! You can do this whenever the result is unambiguous, or—as we just noted—when you must do it (for git checkout branch).

It's true that references exist not only in your own repository, but also in remote repositories. However, Git gives you access to a remote repository's references only at very specific times: namely, during fetch and push operations. You can also use git ls-remote or git remote show to see them, but fetch and push are the more interesting points of contact.

Refspecs

During fetch and push, Git uses strings it calls refspecs to transfer references between the local and remote repository. Thus, it is at these times, and via refspecs, that two Git repositories can get into sync with each other. Once your names are in sync, you can use the same name that someone with the remote uses. There is some special magic here on fetch, though, and it affects both branch names and tag names.

You should think of git fetch as directing your Git to call up (or perhaps text-message) another Git—the "remote"—and have a conversation with it. Early in this conversation, the remote lists all of its references: everything in refs/heads/ and everything in refs/tags/, along with any other references it has. Your Git scans through these and (based on the usual fetch refspec) renames their branches.

Let's take a look at the normal refspec for the remote named origin:

$ git config --get-all remote.origin.fetch
+refs/heads/*:refs/remotes/origin/*
$ 

This refspec instructs your Git to take every name matching refs/heads/*—i.e., every branch on the remote—and change its name to refs/remotes/origin/*, i.e., keep the matched part the same, changing the branch name (refs/heads/) to a remote-tracking branch name (refs/remotes/, specifically, refs/remotes/origin/).

It is through this refspec that origin's branches become your remote-tracking branches for remote origin. Branch name becomes remote-tracking branch name, with the name of the remote, in this case origin, included. The plus sign + at the front of the refspec sets the "force" flag, i.e., your remote-tracking branch will be updated to match the remote's branch name, regardless of what it takes to make it match. (Without the +, branch updates are limited to "fast forward" changes, and tag updates are simply ignored since Git version 1.8.2 or so—before then the same fast-forward rules applied.)

Tags

But what about tags? There's no refspec for them—at least, not by default. You can set one, in which case the form of the refspec is up to you; or you can run git fetch --tags. Using --tags has the effect of adding refs/tags/*:refs/tags/* to the refspec, i.e., it brings over all tags (but does not update your tag if you already have a tag with that name, regardless of what the remote's tag says Edit, Jan 2017: as of Git 2.10, testing shows that --tags forcibly updates your tags from the remote's tags, as if the refspec read +refs/tags/*:refs/tags/*; this may be a difference in behavior from an earlier version of Git).

Note that there is no renaming here: if remote origin has tag xyzzy, and you don't, and you git fetch origin "refs/tags/*:refs/tags/*", you get refs/tags/xyzzy added to your repository (pointing to the same commit as on the remote). If you use +refs/tags/*:refs/tags/* then your tag xyzzy, if you have one, is replaced by the one from origin. That is, the + force flag on a refspec means "replace my reference's value with the one my Git gets from their Git".

Automagic tags during fetch

For historical reasons,³ if you use neither the --tags option nor the --no-tags option, git fetch takes special action. Remember that we said above that the remote starts by displaying to your local Git all of its references, whether your local Git wants to see them or not.⁴ Your Git takes note of all the tags it sees at this point. Then, as it begins downloading any commit objects it needs to handle whatever it's fetching, if one of those commits has the same ID as any of those tags, git will add that tag—or those tags, if multiple tags have that ID—to your repository.

Edit, Jan 2017: testing shows that the behavior in Git 2.10 is now: If their Git provides a tag named T, and you do not have a tag named T, and the commit ID associated with T is an ancestor of one of their branches that your git fetch is examining, your Git adds T to your tags with or without --tags. Adding --tags causes your Git to obtain all their tags, and also force update.

Bottom line

You may have to use git fetch --tags to get their tags. If their tag names conflict with your existing tag names, you may (depending on Git version) even have to delete (or rename) some of your tags, and then run git fetch --tags, to get their tags. Since tags—unlike remote branches—do not have automatic renaming, your tag names must match their tag names, which is why you can have issues with conflicts.

In most normal cases, though, a simple git fetch will do the job, bringing over their commits and their matching tags, and since they—whoever they are—will tag commits at the time they publish those commits, you will keep up with their tags. If you don't make your own tags, nor mix their repository and other repositories (via multiple remotes), you won't have any tag name collisions either, so you won't have to fuss with deleting or renaming tags in order to obtain their tags.

When you need qualified names

I mentioned above that you can omit refs/ almost always, and refs/heads/ and refs/tags/ and so on most of the time. But when can't you?

The complete (or near-complete anyway) answer is in the gitrevisions documentation. Git will resolve a name to a commit ID using the six-step sequence given in the link. Curiously, tags override branches: if there is a tag xyzzy and a branch xyzzy, and they point to different commits, then:

git rev-parse xyzzy

will give you the ID to which the tag points. However—and this is what's missing from gitrevisions—git checkout prefers branch names, so git checkout xyzzy will put you on the branch, disregarding the tag.

In case of ambiguity, you can almost always spell out the ref name using its full name, refs/heads/xyzzy or refs/tags/xyzzy. (Note that this does work with git checkout, but in a perhaps unexpected manner: git checkout refs/heads/xyzzy causes a detached-HEAD checkout rather than a branch checkout. This is why you just have to note that git checkout will use the short name as a branch name first: that's how you check out the branch xyzzy even if the tag xyzzy exists. If you want to check out the tag, you can use refs/tags/xyzzy.)

Because (as gitrevisions notes) Git will try refs/name, you can also simply write tags/xyzzy to identify the commit tagged xyzzy. (If someone has managed to write a valid reference named xyzzy into $GIT_DIR, however, this will resolve as $GIT_DIR/xyzzy. But normally only the various *HEAD names should be in $GIT_DIR.)

¹Okay, okay, "not just to be pedantic". :-)

²Some would say "very not-helpful", and I would tend to agree, actually.

³Basically, git fetch, and the whole concept of remotes and refspecs, was a bit of a late addition to Git, happening around the time of Git 1.5. Before then there were just some ad-hoc special cases, and tag-fetching was one of them, so it got grandfathered in via special code.

⁴If it helps, think of the remote Git as a flasher, in the slang meaning.

On latest version of NPM you can just do:

npm install gitAuthor/gitRepo#tag

If the repo is a valid NPM package it will be auto-aliased in package.json as:

{ "NPMPackageName": "gitAuthor/gitRepo#tag" }

If you could add this to @justingordon 's answer there is no need for manual aliasing now !

And here is how you find the remote tags:

git ls-remote --tags origin

Just wanted to share an alias I created which does the same thing:

Add the following to your ~/.gitconfig

[alias]
    delete-tag = "!f() { \
            echo 'deleting tag' $1 'from remote/origin ausing command: git push --delete origin tagName;'; \
            git push --delete origin $1; \
            echo 'deleting tag' $1 'from local using command: git tag -d tagName;'; \
            git tag -d $1; \
        }; f"

The usage looks like:

-->git delete-tag v1.0-DeleteMe
deleting tag v1.0-DeleteMe from remote/origin ausing command: git push --delete origin tagName;
To https://github.com/jsticha/pafs
 - [deleted]             v1.0-DeleteMe
deleting tag v1.0-DeleteMe from local using command: git tag -d tagName;
Deleted tag 'v1.0-DeleteMe' (was 300d3ef22)

The situation becomes a little bit problematic if we want to create a branch from a tag with the same name.

In this, and in similar scenarios, the important thing is to know: branches and tags are actually single-line text files in .git/refs directory, and we can reference them explicitly using their pathes below .git. Branches are called here "heads", to make our life more simple.

Thus, refs/heads/master is the real, explicit name of the master branch. And refs/tags/cica is the exact name of the tag named cica.

The correct command to create a branch named cica from the tag named cica is:

git branch cica refs/tags/cica

$ git clone

will give you the whole repository.

After the clone, you can list the tags with $ git tag -l and then checkout a specific tag:

$ git checkout tags/<tag_name>

Even better, checkout and create a branch (otherwise you will be on a branch named after the revision number of tag):

$ git checkout tags/<tag_name> -b <branch_name>

You can execute: git describe --tags $(git rev-list --tags --max-count=1) talked here: How to get latest tag name?

When calling just git tag <TAGNAME> without any additional parameters, Git will create a new tag from your current HEAD (i.e. the HEAD of your current branch). When adding additional commits into this branch, the branch HEAD will keep up with those new commits, while the tag always refers to the same commit.

When calling git tag <TAGNAME> <COMMIT> you can even specify which commit to use for creating the tag.

Regardless, a tag is still simply a "pointer" to a certain commit (not a branch).

git fetch upstream --tags

works just fine, it will only get new tags and will not get any other code base.

Even though this is pretty old, I thought I would point out a cool feature I just found for listing tags with commits:

git log --decorate=full

It will show the branches which end/start at a commit, and the tags for commits.

Here is how I rename a tag old to new:

git tag new old
git tag -d old
git push origin new :old

The colon in the push command removes the tag from the remote repository. If you don't do this, Git will create the old tag on your machine when you pull. Finally, make sure that the other users remove the deleted tag. Please tell them (co-workers) to run the following command:

git pull --prune --tags

Note that if you are changing an annotated tag, you need ensure that the new tag name is referencing the underlying commit and not the old annotated tag object that you're about to delete. Therefore, use git tag -a new old^{} instead of git tag new old (this is because annotated tags are objects while lightweight tags are not, more info in this answer).

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

git clone --depth 1 --branch <tag_name> <repo_url>

Example

git clone --depth 1 --branch 0.37.2 https://github.com/apache/incubator-superset.git

<tag_name> : 0.37.2

<repo_url> : https://github.com/apache/incubator-superset.git

Mark Longair's answer (using git show) is close to what is desired in the question. However, it also includes the commit pointed at by the tag, along with the full patch for that commit. Since the commit can be somewhat unrelated to the tag (it's only one commit that the tag is attempting to capture), this may be undesirable. I believe the following is a bit nicer:

for t in `git tag -l`; do git cat-file -p `git rev-parse $t`; done

It's quite simple if you're using SourceTree.

Basically you just need to remove and re-add the conflicting tag:

1. Go to tab Repository -> Tag -> Remove Tag
2. Select the conflicting tag name
3. Check Remove tag from all remotes
4. Press Remove
5. Create new tag with the same name to the proper commit
6. Make sure to check Push all tags when pushing your changes to remote

I'm late to the game here, but another approach could be:

1) create a branch from the tag ($ git checkout -b [new branch name] [tag name])

2) create a pull-request to merge with your new branch into the destination branch

git push --follow-tags

This is a sane option introduced in Git 1.8.3:

git push --follow-tags

It pushes both commits and only tags that are both:

• annotated
• reachable (an ancestor) from the pushed commits

This is sane because:

• you should only push annotated tags to the remote, and keep lightweight tags for local development to avoid tag clashes. See also: What is the difference between an annotated and unannotated tag?
• it won't push annotated tags on unrelated branches

It is for those reasons that --tags should be avoided.

Git 2.4 has added the push.followTags option to turn that flag on by default which you can set with:

git config --global push.followTags true

or by adding followTags = true to the [push] section of your ~/.gitconfig file.

git describe is a porcelain command, which you should avoid:

http://git-blame.blogspot.com/2013/06/checking-current-branch-programatically.html

Instead, I used:

git name-rev --tags --name-only $(git rev-parse HEAD)

To sum up if your remote is called origin and you're working on master branch:

git tag -d <tagname>
git push origin :refs/tags/<tagname>
git tag <tagname> <commitId>
git push origin <tagname>

• Line 1 removes the tag in local env.
• Line 2 removes the tag in remote env.
• Line 3 adds the tag to different commit
• Line 4 pushes the change to the remote

You can also exchange line 4 to git push origin --tags to push all the changes with tags from your local changes.

Basing on @stuart-golodetz, @greg-hewgill, @eedeep, @ben-hocking answers, comments below their answers and NateS comments below my answer.

There's a huge difference. break-all is basically unusable for rendering readable text.

Let's say you've got the string This is a text from an old magazine in a container which only fits 6 chars per row.

word-break: break-all

This i
s a te
xt fro
m an o
ld mag
azine

As you can see the result is awful. break-all will try to fit as many chararacters into each row as possible, it will even split a 2 letter word like "is" onto 2 rows! It's ridiculous. This is why break-all is rarely ever used.

word-wrap: break-word

This
is a
text
from
an old
magazi
ne

break-word will only break words which are too long to ever fit the container (like "magazine", which is 8 chars, and the container only fits 6 chars). It will never break words that could fit the container in their entirety, instead it will push them to a new line.

<div style="width: 100px; border: solid 1px black; font-family: monospace;">_x000D_
  <h1 style="word-break: break-all;">This is a text from an old magazine</h1>_x000D_
  <hr>_x000D_
  <h1 style="word-wrap: break-word;">This is a text from an old magazine</h1>_x000D_
</div

(inline if) in java won't work if you are using 'if' statement .. the right syntax is in the following example:

int y = (c == 19) ? 7 : 11 ; 

or

String y = (s > 120) ? "Slow Down" : "Safe";
System.out.println(y);

as You can see the type of the variable Y is the same as the return value ...

in your case it is better to use the normal if statement not inline if as it is in the pervious answer without "?"

if (compareChar(curChar, toChar("0"))) getButtons().get(i).setText("§");

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.

As pointed by Breedly and Liang, Ashok's solution will prevent you from getting the select value when posting the form.

One slightly different, but still imperfect, way to solve that would be:

class waypointForm(forms.Form):
    def __init__(self, user, *args, **kwargs):
        self.base_fields['waypoints'].choices = self._do_the_choicy_thing()
        super(waypointForm, self).__init__(*args, **kwargs)

This could cause some concurrence problems, though.

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

When one gets the error 'sub-query returns more than 1 row', the database is actually telling you that there is an unresolvable circular reference. It's a bit like using a spreadsheet and saying cell A1 = B1 and then saying B1 = A1. This error is typically associated with a scenario where one needs to have a double nested sub-query. I would recommend you look up a thing called a 'cross-tab query' this is the type of query one normally needs to solve this problem. It's basically an outer join (left or right) nested inside a sub-query or visa versa. One can also solve this problem with a double join (also considered to be a type of cross-tab query) such as below:

CREATE DEFINER=`root`@`localhost` PROCEDURE `SP_GET_VEHICLES_IN`(
    IN P_email VARCHAR(150),
    IN P_credentials VARCHAR(150)
)
BEGIN
    DECLARE V_user_id INT(11);
    SET V_user_id = (SELECT user_id FROM users WHERE email = P_email AND credentials = P_credentials LIMIT 1);
    SELECT vehicles_in.vehicle_id, vehicles_in.make_id, vehicles_in.model_id, vehicles_in.model_year,
    vehicles_in.registration, vehicles_in.date_taken, make.make_label, model.model_label
    FROM make
    LEFT OUTER JOIN vehicles_in ON vehicles_in.make_id = make.make_id
    LEFT OUTER JOIN model ON model.make_id = make.make_id AND vehicles_in.model_id = model.model_id
    WHERE vehicles_in.user_id = V_user_id;
END

In the code above notice that there are three tables in amongst the SELECT clause and these three tables show up after the FROM clause and after the two LEFT OUTER JOIN clauses, these three tables must be distinct amongst the FROM and LEFT OUTER JOIN clauses to be syntactically correct.

It is noteworthy that this is a very important construct to know as a developer especially if you're writing periodical report queries and it's probably the most important skill for any complex cross referencing, so all developers should study these constructs (cross-tab and double join).

Another thing I must warn about is: If you are going to use a cross-tab as a part of a working system and not just a periodical report, you must check the record count and reconfigure the join conditions until the minimum records are returned, otherwise large tables and cross-tabs can grind your server to a halt. Hope this helps.

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)

Once the user have choose a image you can read the file-path of the chosen image and place it into your html.

Example:

<form id="form1" runat="server">
    <input type='file' id="imgInp" />
    <img id="blah" src="#" alt="your image" />
</form>

Javascript:

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

I just wanted to illustrate that the built-in solutions (SQL-only) are not always the best ones. At first I thought that because Django's QuerySet.objects.order_by method accepts multiple arguments, you could easily chain them:

ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]

But, it does not work as you would expect. Case in point, first is a list of presidents sorted by score (selecting top 5 for easier reading):

>>> auths = Author.objects.order_by('-score')[:5]
>>> for x in auths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

Using Alex Martelli's solution which accurately provides the top 5 people sorted by last_name:

>>> for x in sorted(auths, key=operator.attrgetter('last_name')): print x
... 
Benjamin Harrison (467)
James Monroe (487)
Gerald Rudolph (464)
Ulysses Simpson (474)
Harry Truman (471)

And now the combined order_by call:

>>> myauths = Author.objects.order_by('-score', 'last_name')[:5]
>>> for x in myauths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

As you can see it is the same result as the first one, meaning it doesn't work as you would expect.

If you have short strings you should be able to create a few LIKE patterns ('[^a-zA-Z0-9]', '[^a-zA-Z0-9][^a-zA-Z0-9]', ...) to match strings of different length. Otherwise you should use CLR user defined function and a proper regular expression - Regular Expressions Make Pattern Matching And Data Extraction Easier.

If you don't need a Terminal window, you can make any executable file an Application just by creating a shell script Example and moving it to the filename Example.app/Contents/MacOS/Example. You can place this new application in your dock like any other, and execute it with a click.

NOTE: the name of the app must exactly match the script name. So the top level directory has to be Example.app and the script in the Contents/MacOS subdirectory must be named Example, and the script must be executable.

If you do need to have the terminal window displayed, I don't have a simple solution. You could probably do something with Applescript, but that's not very clean.

find /dev -maxdepth 1 -name 'abc-*'

Does not work for me. It return nothing. If I just do '.' it gives me all the files in directory below the one I'm working in on.

find /dev -maxdepth 1 -name "*.root" -type 'f' -size +100k -ls

Return nothing with '.' instead I get list of all 'big' files in my directory as well as the rootfiles/ directory where I store old ones.

Continuing. This works.

Apparently /dev means directory of interest. But ./ is needed, not just .. The need for the / was not obvious even after I figured out what /dev meant more or less.

There is a certain issue in below answer as it is not checking whole string due to absence of [ ] while checking the characters and numerals, this is correct version

The following should be clean (using find_package) and work (the find module is called FindThreads):

cmake_minimum_required (VERSION 2.6) 
find_package (Threads)
add_executable (myapp main.cpp ...)
target_link_libraries (myapp ${CMAKE_THREAD_LIBS_INIT})

I believe that there can still be and valid logic on views. But for this kind of things I agree with @BigMike, it is better placed on the model. Having said that the problem can be solved in three ways:

Your answer (assuming this works, I haven't tried this):

<div class="details @(@Model.Details.Count > 0 ? "show" : "hide")">

Second option:

@if (Model.Details.Count > 0) {
    <div class="details show">
}
else {
    <div class="details hide">
}

Third option:

<div class="@("details " + (Model.Details.Count>0 ? "show" : "hide"))">

Have a look at the ReadAsset.java from API samples that come with the SDK.

       try {
        InputStream is = getAssets().open("read_asset.txt");

        // We guarantee that the available method returns the total
        // size of the asset...  of course, this does mean that a single
        // asset can't be more than 2 gigs.
        int size = is.available();

        // Read the entire asset into a local byte buffer.
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        // Convert the buffer into a string.
        String text = new String(buffer);

        // Finally stick the string into the text view.
        TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(text);
    } catch (IOException e) {
        // Should never happen!
        throw new RuntimeException(e);
    }

lstpp is empty. You cant access the first element of an empty list.

In general, you can check if size > index.

In your case, you need to check if lstpp is empty. (you can use !lstpp.isEmpty())

You can use replace:

df['y'] = df['y'].replace({'N/A': np.nan})

Also be aware of the inplace parameter for replace. You can do something like:

df.replace({'N/A': np.nan}, inplace=True)

This will replace all instances in the df without creating a copy.

Similarly, if you run into other types of unknown values such as empty string or None value:

df['y'] = df['y'].replace({'': np.nan})

df['y'] = df['y'].replace({None: np.nan})

As often, numbers says more than feeling, here are some data: Pipe vs Unix Socket Performance (opendmx.net).

This benchmark shows a difference of about 12 to 15% faster speed for pipes.

Note: To make the most voted solution work, attributes in the POJO have to be public or have a public getter/setter:

By default, Jackson 2 will only work with fields that are either public, or have a public getter method – serializing an entity that has all fields private or package private will fail.

Not tested yet, but I believe that this rule also applies for other JSON libs like google Gson.

As far as I know python will compile all modules you "import". However python will NOT compile a python script run using: "python script.py" (it will however compile any modules that the script imports).

The real questions is why you don't want python to compile the modules? You could probably automate a way of cleaning these up if they are getting in the way.

ChangeDetectorRef.detectChanges() - similar to $scope.$digest() -- i.e., check only this component and its children

No, it is like I want to run Form_Load of Form A,if it is possible

-- Varun Mahajan

The usual way to do this is to put the relevant code in a procedure that can be called by both forms. It is best put the code in a standard module, but you could have it on Form a:

Form B:

Sub RunFormALoad()
   Forms!FormA.ToDoOnLoad
End Sub

Form A:

Public Sub Form_Load()
    ToDoOnLoad
End Sub    

Sub ToDoOnLoad()
    txtText = "Hi"

There is no problem with your web.config. Your web site runs under a process. In iis you can define the identity of that process. The identity that your web site's application pool runs as (Network Services, Local System, etc.), should have permission to access and read web.config file.

Update:

This updated answer is same as above, but a little longer and simpler and improved.

First of all: you don't have to change anything in your config file. It's OK. The problem is with windows file permissions.

This problems occurs because your application can not access and read web.config file.

Make the file accessible to IIS_IUSRS group. Just right click web.config and click properties, under security tab, add IIS_IUSRS.

So what is this IIS_IUSRS thing?

Your web site is like an exe file. Just like any exe file, it should be started by a user and it runs according to permissions assigned to that user.

When your site is started in IIS, Application Pool of your web site is associated with a user (Network Services, Local System, Etc. ...) (and can be changed in IIS)

So when you say IIS_IUSRS, it means any user (Network Services, Local System, Etc. ...) that your site is running as.

And as @Seph mentioned in comment below: If your computer is on a domain, remember that IIS_IUSRS group is a local group. Also make sure that when you're trying to find this user check the location it should be set to local computer and not a corporate domain.

I wrote this one today while trying to recreate _.sortBy in TypeScript, and thought I would leave it for anyone in need.

// ** Credits for getKeyValue at the bottom **
export const getKeyValue = <T extends {}, U extends keyof T>(key: U) => (obj: T) => obj[key] 

export const sortBy = <T extends {}>(index: string, list: T[]): T[] => {
    return list.sort((a, b): number => {
        const _a = getKeyValue<keyof T, T>(index)(a)
        const _b = getKeyValue<keyof T, T>(index)(b)
        if (_a < _b) return -1
        if (_a > _b) return 1
        return 0
    })
}

Usage:

It expects an array of generic type T, hence the cast for <T extends {}>, as well as typing the parameter and function return type with T[]

const x = [{ label: 'anything' }, { label: 'goes'}]
const sorted = sortBy('label', x)

1. The easiest way is to click on that commit and add a tag to that commit. I have included the tag 'last_commit' with this commit

2. Than go to downloads in the left corner of the side nav in bit bucket. Click on download in the left side

3. Now click on tags in the nav bar and download the zip from the UI. Find your tag and download the zip

You can't. Security stops you for knowing anything about the filing system of the client computer - it may not even have one! It could be a MAC, a PC, a Tablet or an internet enabled fridge - you don't know, can't know and won't know. And letting you have the full path could give you some information about the client - particularly if it is a network drive for example.

In fact you can get it under particular conditions, but it requires an ActiveX control, and will not work in 99.99% of circumstances.

You can't use it to restore the file to the original location anyway (as you have absolutely no control over where downloads are stored, or even if they are stored) so in practice it is not a lot of use to you anyway.

You can make it easier in your code (if you're doing this a lot anyway) by using an extension on the DataRow object, like:

static class Extensions
{
    public static string GetColumn(this DataRow Row, int Ordinal)
    {
        return Row.Table.Columns[Ordinal].ColumnName;
    }
}

Then call it using:

string MyColumnName = MyRow.GetColumn(5);

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

A general solution would be to use a linux box (could be in a virtual machine) configured as a transparent proxy to intercept the traffic, and then analyse it using wireshark or tcpdump or whatever you like. Perhaps MacOS can do this also, I haven't tried.

Or if you can run the app in the simulator, you can probably monitor the traffic on your own machine.

ListBox will try to expand in height that is available.. When you set the Height property of ListBox you get a scrollviewer that actually works...

If you wish your ListBox to accodate the height available, you might want to try to regulate the Height from your parent controls.. In a Grid for example, setting the Height to Auto in your RowDefinition might do the trick...

if ( ( param & karen ) == karen )
{
  // Do stuff
}

The bitwise 'and' will mask out everything except the bit that "represents" Karen. As long as each person is represented by a single bit position, you could check multiple people with a simple:

if ( ( param & karen ) == karen )
{
  // Do Karen's stuff
}
if ( ( param & bob ) == bob )
  // Do Bob's stuff
}

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

To make this simple: PyPy provides the speed that's lacked by CPython but sacrifices its compatibility. Most people, however, choose Python for its flexibility and its "battery-included" feature (high compatibility), not for its speed (it's still preferred though).

Additionally to those above, I added __file__ for the name so the picture and Python file get the same names. I also added few arguments to make It look better:

# Saves a PNG file of the current graph to the folder and updates it every time
# (nameOfimage, dpi=(sizeOfimage),Keeps_Labels_From_Disappearing)
plt.savefig(__file__+".png",dpi=(250), bbox_inches='tight')
# Hard coded name: './test.png'

The double space generally works well. However, sometimes the lacking newline in the PDF still occurs to me when using four pound sign sub titles #### in Jupyter Notebook, as the next paragraph is put into the subtitle as a single paragraph. No amount of double spaces and returns fixed this, until I created a notebook copy 'v. PDF' and started using a single backslash '\' which also indents the next paragraph nicely:

#### 1.1 My Subtitle  \

1.1 My Subtitle
    Next paragraph text.

An alternative to this, is to upgrade the level of your four # titles to three # titles, etc. up the title chain, which will remove the next paragraph indent and format the indent of the title itself (#### My Subtitle ---> ### My Subtitle).

### My Subtitle


1.1 My Subtitle

Next paragraph text.

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010) at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.

This shortcut prepares an environment by calling a script vcvarsall.bat where the compiler, linker, etc. are setup from the right Visual Studio installation.

Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:

:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat

or

:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat

However:

Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:

cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"

Run cmake --help to get a list of all possible generators.

Attaching / Detaching

Eloquent also provides a few additional helper methods to make working with related models more convenient. For example, let's imagine a user can have many roles and a role can have many users. To attach a role to a user by inserting a record in the intermediate table that joins the models, use the attach method:

$user = App\User::find(1);

$user->roles()->attach($roleId);

When attaching a relationship to a model, you may also pass an array of additional data to be inserted into the intermediate table:

$user->roles()->attach($roleId, ['expires' => $expires]);

You can also use Sync if you want to remove old roles and only keep the new ones you are attaching now

$user->roles()->sync([1 => ['expires' => $expires], 2 => ['expires' => $expires]);

The default behaviour can be changed by passing a 'false' as a second argument. This will attach the roles with ids 1,2,3 without affecting the existing roles.

In this mode sync behaves similar to the attach method.

$user->roles()->sync([1 => ['expires' => $expires], 2 => ['expires' => $expires], false);

How about iPhone Configuration Utility?

http://support.apple.com/kb/DL1465?viewlocale=en_US&locale=en_US

iPhone Configuration Utility lets you easily create, maintain, encrypt, and install configuration profiles, track and install provisioning profiles and authorized applications, and capture device information including console logs.

Apple Configurator replaces iPhone Configuration Utility. With the the release of iOS 8, iPhone Configuration Utility is no longer supported or available for download. https://itunes.apple.com/gb/app/apple-configurator/id434433123

1. origin - This is a custom and most common name to point to remote.

$ git remote add origin https://github.com/git/git.git --- You will run this command to link your github project to origin. Here origin is user-defined. You can rename it by $ git remote rename old-name new-name

2. master - The default branch name in Git is master. For both remote and local computer.

3. origin/master - This is just a pointer to refer master branch in remote repo. Remember i said origin points to remote.

$ git fetch origin - Downloads objects and refs from remote repository to your local computer [origin/master]. That means it will not affect your local master branch unless you merge them using $ git merge origin/master. Remember to checkout the correct branch where you need to merge before run this command

Note: Fetched content is represented as a remote branch. Fetch gives you a chance to review changes before integrating them into your copy of the project. To show changes between yours and remote $git diff master..origin/master

Go to designer.cs file of the form in which you have the grid view and comment the following line: - //this.dataGridView1.AlternatingRowsDefaultCellStyle = dataGridViewCellStyle1;

if you are using vs 2008 or .net framework 3.5 as it will be by default applied to alternating rows.

Using the inline-block is better because it doesn't force the remaining elements and/or controls to be drawn in a new line.

label {
  width:200px;
  display: inline-block;
}

You may also want to check to make sure your not replacing an occurrence that has already been replaced. You can use a regular expression with negative lookahead to do this.

For example:

String str = "sdasdasa&adas&dasdasa";  
str = str.replaceAll("&(?!amp;)", "&");

This would result in the string "sdasdasa&adas&dasdasa".

The regex pattern "&(?!amp;)" basically says: Match any occurrence of '&' that is not followed by 'amp;'.

Since you mentioned it's always going to have a length of 4, I won't be doing any error checking to make this slick. ;)

function pad(input) {
    var BASE = "0000";
    return input ? BASE.substr(0, 4 - Math.ceil(input / 10)) + input : BASE;
}

Idea: Simply replace '0000' with number provided... Issue with that is, if input is 0, I need to hard-code it to return '0000'. LOL.

This should be slick enough.

Edit - Contained User (v12 and later)

As of Sql Azure 12, databases will be created as Contained Databases which will allow users to be created directly in your database, without the need for a server login via master.

CREATE USER [MyUser] WITH PASSWORD = 'Secret';
ALTER ROLE [db_datareader] ADD MEMBER [MyUser];

Note when connecting to the database when using a contained user that you must always specify the database in the connection string.

Traditional Server Login - Database User (Pre v 12)

Just to add to @Igorek's answer, you can do the following in Sql Server Management Studio:

Create the new Login on the server
In master (via the Available databases drop down in SSMS - this is because USE master doesn't work in Azure):

create the login:

CREATE LOGIN username WITH password='password';

Create the new User in the database
Switch to the actual database (again via the available databases drop down, or a new connection)

CREATE USER username FROM LOGIN username;

(I've assumed that you want the user and logins to tie up as username, but change if this isn't the case.)

Now add the user to the relevant security roles

EXEC sp_addrolemember N'db_owner', N'username'
GO

(Obviously an app user should have less privileges than dbo.)

Don't know if this is too late, but the way I solved this was to draw four thin rectangles that together made up a one big border. Drawing the border with one rectangle seems to be undoable since they're all opaque, so you should draw each edge of the border separately.

I was trying to measure the time between events with the exception of what one entry that has multiple processes between the start and end. I needed this in the context of other single line processes.

I used a select with an inner join as my select statement within the Nth cte. The second cte I needed to extract the start date on X and end date on Y and used 1 as an id value to left join to put them on a single line.

You can make use of Gson library to convert your java classes to JSON objects.

Create a pojo class for variables you want to send as per above Example

{"name":"myname","age":"20"}

becomes

class pojo1
{
   String name;
   String age;
   //generate setter and getters
}

once you set the variables in pojo1 class you can send that using the following code

String       postUrl       = "www.site.com";// put in your url
Gson         gson          = new Gson();
HttpClient   httpClient    = HttpClientBuilder.create().build();
HttpPost     post          = new HttpPost(postUrl);
StringEntity postingString = new StringEntity(gson.toJson(pojo1));//gson.tojson() converts your pojo to json
post.setEntity(postingString);
post.setHeader("Content-type", "application/json");
HttpResponse  response = httpClient.execute(post);

and these are the imports

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;

and for GSON

import com.google.gson.Gson;

Strangely enough, the solution ended up being to change

The cleanest way is to not (directly) use an iterator at all:

• type your map with generics
• use a foreach loop to iterate over the entries:

Like this:

Map<Integer, String> hm = new HashMap<Integer, String>();

hm.put(0, "zero");
hm.put(1, "one");

for (Map.Entry<Integer, String> entry : hm.entrySet()) {
    // do something with the entry
    System.out.println(entry.getKey() + " - " + entry.getValue());
    // the getters are typed:
    Integer key = entry.getKey();
    String value = entry.getValue();
}

This is way more efficient than iterating over keys, because you avoid n calls to get(key).

You may want to do this all the time by default. I've been struggling to wrap the jquery function or jquery.fn.init method to do this without error, but you can make a simple change to the jquery source to do this. Included are some surrounding lines you can search for. I recommend searching jquery source for The jQuery object is actually just the init constructor 'enhanced'

var
  version = "3.3.1",

  // Define a local copy of jQuery
  jQuery = function( selector, context ) {

    // The jQuery object is actually just the init constructor 'enhanced'
    // Need init if jQuery is called (just allow error to be thrown if not included)
    var result = new jQuery.fn.init( selector, context );
    if ( result.length === 0 ) {
      if (window.console && console.warn && context !== 'failsafe') {
        if (selector != null) {
          console.warn(
            new Error('$(\''+selector+'\') selected nothing. Do $(sel, "failsafe") to silence warning. Context:'+context)
          );
        }
      }
    }
    return result;
  },

  // Support: Android <=4.0 only
  // Make sure we trim BOM and NBSP
  rtrim = /^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g;

jQuery.fn = jQuery.prototype = {

Last but not least, you can get the uncompressed jquery source code here: http://code.jquery.com/

The default namespace in Python is "__main__". When you use import scipy, Python creates a separate namespace as your module name. The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.

Modify your estimated population function to take a growth argument of type float. Then you can call the growthRate function with your birthRate and deathRate and use the return value as the input for grown into estimatedPopulation.

float growthRate (float birthRate, float deathRate)     
{    
    return ((birthRate) - (deathRate));    
}

int estimatedPopulation (int currentPopulation, float growth)
{
    return ((currentPopulation) + (currentPopulation) * (growth / 100);
}

// main.cpp
int currentPopulation = 100;
int births = 50;
int deaths = 25;
int population = estimatedPopulation(currentPopulation, growthRate(births, deaths));

   values are of type double and are accurate within the precision of  the
   double type.

   M_PI   Value of pi

   M_PI_2 Value of pi/2

   M_PI_4 Value of pi/4

   M_1_PI Value of 1/pi

   M_2_PI Value of 2/pi

   M_2_SQRTPI
          Value of 2/ sqrt pi

10,000? 70,000? is that all :)

FreeBSD is probably the server you want, Here's a little blog post about tuning it to handle 100,000 connections, its has had some interesting features like zero-copy sockets for some time now, along with kqueue to act as a completion port mechanism.

Solaris can handle 100,000 connections back in the last century!. They say linux would be better

The best description I've come across is this presentation/paper on writing a scalable webserver. He's not afraid to say it like it is :)

Same for software: the cretins on the application layer forced great innovations on the OS layer. Because Lotus Notes keeps one TCP connection per client open, IBM contributed major optimizations for the ”one process, 100.000 open connections” case to Linux

And the O(1) scheduler was originally created to score well on some irrelevant Java benchmark. The bottom line is that this bloat bene?ts all of us.

You can use ARG - see https://docs.docker.com/engine/reference/builder/#arg

The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag. If a user specifies a build argument that was not defined in the Dockerfile, the build outputs an error.

This should be working too using JPA 2.0 @MapsId annotation instead of Hibernate's GenericGenerator:

@Entity
public class Person {

    @Id
    @GeneratedValue
    public int id;

    @OneToOne
    @PrimaryKeyJoinColumn
    public OtherInfo otherInfo;

    rest of attributes ...
}

@Entity
public class OtherInfo {

    @Id
    public int id;

    @MapsId
    @OneToOne
    @JoinColumn(name="id")
    public Person person;

    rest of attributes ...
}

More details on this in Hibernate 4.1 documentation under section 5.1.2.2.7.

select * from table_name 
where `date` between curdate() - dayofmonth(curdate()) + 1
                 and curdate()

SQLFiddle example

if (/(^|;)\s*visited=/.test(document.cookie)) {
    alert("Hello again!");
} else {
    document.cookie = "visited=true; max-age=" + 60 * 60 * 24 * 10; // 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 10 days.
    alert("This is your first time!");
}

is one way to do it. Note that document.cookie is a magic property, so you don't have to worry about overwriting anything, either.

There are also more convenient libraries to work with cookies, and if you don’t need the information you’re storing sent to the server on every request, HTML5’s localStorage and friends are convenient and useful.

Kiwi Browser is mobile Chromium and allows installing extensions. Install Kiwi and then install "Mini JS console" Chrome extension(just search in Google and install from Chrome extensions website, uBlock also works ;). It will become available in Kiwi menu at the bottom and will show the console output for the current page.

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

Its actually enough to add -m to startup parameters on Sql Server Configuration Manager, restart service, go to ssms an add checkbox sysadmin on your account, then remove -m restart again and use as usual.

Database Engine Service Startup Options

-m Starts an instance of SQL Server in single-user mode.

.gitignore

is a text file comprising a list of files in your directory that git will ignore or not add/update in the repository.

.gitkeep

Since Git removes or doesn't add empty directories to a repository, .gitkeep is sort of a hack (I don't think it's officially named as a part of Git) to keep empty directories in the repository.

Just do a touch /path/to/emptydirectory/.gitkeep to add the file, and Git will now be able to maintain this directory in the repository.

QueueHandler is native in Python 3.2+, and does exactly this. It is easily replicated in previous versions.

Python docs have two complete examples: Logging to a single file from multiple processes

For those using Python < 3.2, just copy QueueHandler into your own code from: https://gist.github.com/vsajip/591589 or alternatively import logutils.

Each process (including the parent process) puts its logging on the Queue, and then a listener thread or process (one example is provided for each) picks those up and writes them all to a file - no risk of corruption or garbling.

for jackson 1.9.10 I use

ObjectMapper mapper = new ObjectMapper();

mapper.setVisibility(JsonMethod.ALL, Visibility.NONE);
mapper.setVisibility(JsonMethod.FIELD, Visibility.ANY);

to turn of auto dedection.

You may want to take a different approach: Instead of changing the css dynamically, predefine your styles in CSS the way you want them. Then use JQuery to add and remove styles from within Javascript. (see code from Ajmal)

"hello _there_".replace(/_(.*?)_/, function(a, b){
    return '<div>' + b + '</div>';
})

Oh, or you could also:

"hello _there_".replace(/_(.*?)_/, "<div>$1</div>")

EDIT by Liran H: For six other people including myself, $1 did not work, whereas \1 did.

I think Nosql is "more suitable" in these scenarios at least (more supplementary is welcome)

1. Easy to scale horizontally by just adding more nodes.

2. Query on large data set

   Imagine tons of tweets posted on twitter every day. In RDMS, there could be tables with millions (or billions?) of rows, and you don't want to do query on those tables directly, not even mentioning, most of time, table joins are also needed for complex queries.

3. Disk I/O bottleneck

   If a website needs to send results to different users based on users' real-time info, we are probably talking about tens or hundreds of thousands of SQL read/write requests per second. Then disk i/o will be a serious bottleneck.

The first section is called a protocol and yes you can register your own. On Windows (where I'm assuming you're doing this given the C# tag - sorry Mono fans), it's done via the registry.

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

This is an example of how to set time in a div(only_time) using javascript.

function date_time() {
    var date = new Date();
    var am_pm = "AM";
    var hour = date.getHours();
    if(hour>=12){
        am_pm = "PM";
    }
    if (hour == 0) {
        hour = 12;
    }
    if(hour>12){
        hour = hour - 12;
    }
    if(hour<10){
        hour = "0"+hour;
    }

    var minute = date.getMinutes();
    if (minute<10){
        minute = "0"+minute;
    }
    var sec = date.getSeconds();
    if(sec<10){
        sec = "0"+sec;
    }

    document.getElementById("time").innerHTML =  hour+":"+minute+":"+sec+" "+am_pm;
}
setInterval(date_time,500);
<per>
<div class="date" id="time"></div>
</per>

abc(?!def) will match abc not followed by def. So it'll match abce, abc, abck, etc. what if I want neither def nor xyz will it be abc(?!(def)(xyz)) ???

I had the same question and found a solution:

abc(?:(?!def))(?:(?!xyz))

These non-counting groups are combined by "AND", so it this should do the trick. Hope it helps.

This snippet may be useful when you know the length of the original content (e.g. a checksum). It checks that encoded form has the correct length.

public static boolean isValidBase64( final int initialLength, final String string ) {
  final int padding ;
  final String regexEnd ;
  switch( ( initialLength ) % 3 ) {
    case 1 :
      padding = 2 ;
      regexEnd = "==" ;
      break ;
    case 2 :
      padding = 1 ;
      regexEnd = "=" ;
      break ;
    default :
      padding = 0 ;
      regexEnd = "" ;
  }
  final int encodedLength = ( ( ( initialLength / 3 ) + ( padding > 0 ? 1 : 0 ) ) * 4 ) ;
  final String regex = "[a-zA-Z0-9/\\+]{" + ( encodedLength - padding ) + "}" + regexEnd ;
  return Pattern.compile( regex ).matcher( string ).matches() ;
}

If you add the fragment in XML, you can't swap them dynamically. What happens is they overly, so they events don't fire as one would expect. The issue is documented in this question. FragmenManager replace makes overlay

Turn middle_fragment into a FrameLayout, and load it like below and your events will fire.

getFragmentManager().beginTransation().
    add(R.id.middle_fragment, new MiddleFragment()).commit();

First of all go to the device manager now go to View>>select Show hidden devices....Then go to network adapters and find out Microsoft Hosted network Virual Adapter ....Press right click and enable the option....

Then go to command prompt with administrative privileges and enter the following commands:

netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork

Your Hostednetwork will work without any problems.

The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):

import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')

plt.show()

print(fpath) will show you where you should put the .ttf.

You can see the output here: https://matplotlib.org/gallery/api/font_file.html

I had similiar issue but only with Chrome, Firefox was working. I noticed that Chrome was adding an Origin parameter in the header request.

So in my nginx.conf I added the parameter to avoid it under location/ block

proxy_set_header Origin "";

If you want to store the list of ignored files outside of your Git tree, you can use the .git/info/exclude file. It is applied only to your checkout of the repo.

If you would like to redirect the user after the alert, do this:

echo ("<script LANGUAGE='JavaScript'>
          window.alert('Succesfully Updated');
          window.location.href='<URL to redirect to>';
       </script>");

If you are looking for readability, I believe that this is that code:

print '%(kg).2f kg = %(lb).2f lb = %(gal).2f gal = %(l).2f l' % {
    'kg': var1,
    'lb': var2,
    'gal': var3,
    'l': var4,
}

Another alternative to simulating a F5 key press would be to simply host the WebBrowser control in the Window Forms application. You use the WebBrowser.Navigate method to load your web page and then use a standard Timer and on each tick of the timer you just re-Navigate to the url which will reload the page.

Let's take a look at what happens when you select a file and submit your form (I've truncated the headers for brevity):

POST /upload?upload_progress_id=12344 HTTP/1.1
Host: localhost:3000
Content-Length: 1325
Origin: http://localhost:3000
... other headers ...
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryePkpFF7tjBAqx29L

------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="MAX_FILE_SIZE"

100000
------WebKitFormBoundaryePkpFF7tjBAqx29L
Content-Disposition: form-data; name="uploadedfile"; filename="hello.o"
Content-Type: application/x-object

... contents of file goes here ...
------WebKitFormBoundaryePkpFF7tjBAqx29L--

NOTE: each boundary string must be prefixed with an extra --, just like in the end of the last boundary string. The example above already includes this, but it can be easy to miss. See comment by @Andreas below.

Instead of URL encoding the form parameters, the form parameters (including the file data) are sent as sections in a multipart document in the body of the request.

In the example above, you can see the input MAX_FILE_SIZE with the value set in the form, as well as a section containing the file data. The file name is part of the Content-Disposition header.

The full details are here.

In the latest version of the support library (23.0.0+), TextInputLayout takes the following attribute in XML to edit the floating label color: android:textColorHint="@color/white"

You want to build the regular expression dynamically and for this the proper solutuion is to use the new RegExp(string) constructor. In order for constructor to treat special characters literally, you must escape them. There is a built-in function in jQuery UI autocomplete widget called $.ui.autocomplete.escapeRegex:

[...] you can make use of the built-in $.ui.autocomplete.escapeRegex function. It'll take a single string argument and escape all regex characters, making the result safe to pass to new RegExp().

If you are using jQuery UI you can use that function, or copy its definition from the source:

function escapeRegex( value ) {
    return value.replace( /[\-\[\]{}()*+?.,\\\^$|#\s]/g, "\\$&" );
}

And use it like this:

"[z-a][z-a][z-a]".replace(new RegExp(escapeRegex("[z-a]"), "g"), "[a-z]");
//            escapeRegex("[z-a]")       -> "\[z\-a\]"
// new RegExp(escapeRegex("[z-a]"), "g") -> /\[z\-a\]/g
// end result                            -> "[a-z][a-z][a-z]"

i used this, and it worked:

var cleanText = text.replace(/ /g,"");

This seems to work for me, an example for waiting until the processor reaches a certain percentage

var cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
int usage = (int) cpuCounter.NextValue();
while (usage == 0 || usage > 80)
{
     Thread.Sleep(250);
     usage = (int)cpuCounter.NextValue();
}

In my case, disabling Chrome Extensions fixed it. I removed them from Chrome one by one until I found the culprit.

Since I'm the author of the offending Chrome extension, I guess I better fix the extension!

I have an implementation as part of a spreadsheet project.

This code is not yet tested thoroughly, but anyone is welcome to use it.

As some of the answers noted though, your implementation can be much simpler if you actually have DSV or TSV file, as they disallow the use of the record and field separators in the values. CSV, on the other hand, can actually have commas and newlines inside a field, which breaks most regular expression and split-based approaches.

var CSV = {
    parse: function(csv, reviver) {
        reviver = reviver || function(r, c, v) { return v; };
        var chars = csv.split(''), c = 0, cc = chars.length, start, end, table = [], row;
        while (c < cc) {
            table.push(row = []);
            while (c < cc && '\r' !== chars[c] && '\n' !== chars[c]) {
                start = end = c;
                if ('"' === chars[c]){
                    start = end = ++c;
                    while (c < cc) {
                        if ('"' === chars[c]) {
                            if ('"' !== chars[c+1]) {
                                break;
                            }
                            else {
                                chars[++c] = ''; // unescape ""
                            }
                        }
                        end = ++c;
                    }
                    if ('"' === chars[c]) {
                        ++c;
                    }
                    while (c < cc && '\r' !== chars[c] && '\n' !== chars[c] && ',' !== chars[c]) {
                        ++c;
                    }
                } else {
                    while (c < cc && '\r' !== chars[c] && '\n' !== chars[c] && ',' !== chars[c]) {
                        end = ++c;
                    }
                }
                row.push(reviver(table.length-1, row.length, chars.slice(start, end).join('')));
                if (',' === chars[c]) {
                    ++c;
                }
            }
            if ('\r' === chars[c]) {
                ++c;
            }
            if ('\n' === chars[c]) {
                ++c;
            }
        }
        return table;
    },

    stringify: function(table, replacer) {
        replacer = replacer || function(r, c, v) { return v; };
        var csv = '', c, cc, r, rr = table.length, cell;
        for (r = 0; r < rr; ++r) {
            if (r) {
                csv += '\r\n';
            }
            for (c = 0, cc = table[r].length; c < cc; ++c) {
                if (c) {
                    csv += ',';
                }
                cell = replacer(r, c, table[r][c]);
                if (/[,\r\n"]/.test(cell)) {

                }
                csv += (cell || 0 === cell) ? cell : '';
            }

Check via Google, there are lots of examples, see here for one.

You should first pull the changes from the develop branch and only then merge them to your branch:

git checkout develop 
git pull 
git checkout branch-x
git rebase develop

Or, when on branch-x:

git fetch && git rebase origin/develop

I have an alias that saves me a lot of time. Add to your ~/.gitconfig:

[alias]
    fr = "!f() { git fetch && git rebase origin/"$1"; }; f"

Now, all that you have to do is:

git fr develop

I'd rather use more convenient itemSelect event. With this event you can use org.primefaces.event.SelectEvent objects in your listener.

<p:selectOneMenu ...>
    <p:ajax event="itemSelect" 
        update="messages"
        listener="#{beanMB.onItemSelectedListener}"/>
</p:selectOneMenu>

With such listener:

public void onItemSelectedListener(SelectEvent event){
    MyItem selectedItem = (MyItem) event.getObject();
    //do something with selected value
}

Another options is to use the search method as follow:

if (referrer.search(new RegExp("Ral", "i")) == -1) { ...

It looks more elegant then converting the whole string to lower case and it may be more efficient.
With toLowerCase() the code have two pass over the string, one pass is on the entire string to convert it to lower case and another is to look for the desired index.
With RegExp the code have one pass over the string which it looks to match the desired index.

Therefore, on long strings I recommend to use the RegExp version (I guess that on short strings this efficiency comes on the account of creating the RegExp object though)

Don't pass db models directly to your views. You're lucky enough to be using MVC, so encapsulate using view models.

Create a view model class like this:

public class EmployeeAddViewModel
{
    public Employee employee { get; set; }
    public Dictionary<int, string> staffTypes { get; set; }
    // really? a 1-to-many for genders
    public Dictionary<int, string> genderTypes { get; set; }

    public EmployeeAddViewModel() { }
    public EmployeeAddViewModel(int id)
    {
        employee = someEntityContext.Employees
            .Where(e => e.ID == id).SingleOrDefault();

        // instantiate your dictionaries

        foreach(var staffType in someEntityContext.StaffTypes)
        {
            staffTypes.Add(staffType.ID, staffType.Type);
        }

        // repeat similar loop for gender types
    }
}

Controller:

[HttpGet]
public ActionResult Add()
{
    return View(new EmployeeAddViewModel());
}

[HttpPost]
public ActionResult Add(EmployeeAddViewModel vm)
{
    if(ModelState.IsValid)
    {
        Employee.Add(vm.Employee);
        return View("Index"); // or wherever you go after successful add
    }

    return View(vm);
}

Then, finally in your view (which you can use Visual Studio to scaffold it first), change the inherited type to ShadowVenue.Models.EmployeeAddViewModel. Also, where the drop down lists go, use:

@Html.DropDownListFor(model => model.employee.staffTypeID,
    new SelectList(model.staffTypes, "ID", "Type"))

and similarly for the gender dropdown

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(model.genderTypes, "ID", "Gender"))

Update per comments

For gender, you could also do this if you can be without the genderTypes in the above suggested view model (though, on second thought, maybe I'd generate this server side in the view model as IEnumerable). So, in place of new SelectList... below, you would use your IEnumerable.

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(new SelectList()
    {
        new { ID = 1, Gender = "Male" },
        new { ID = 2, Gender = "Female" }
    }, "ID", "Gender"))

Finally, another option is a Lookup table. Basically, you keep key-value pairs associated with a Lookup type. One example of a type may be gender, while another may be State, etc. I like to structure mine like this:

ID | LookupType | LookupKey | LookupValue | LookupDescription | Active
1  | Gender     | 1         | Male        | male gender       | 1
2  | State      | 50        | Hawaii      | 50th state        | 1
3  | Gender     | 2         | Female      | female gender     | 1
4  | State      | 49        | Alaska      | 49th state        | 1
5  | OrderType  | 1         | Web         | online order      | 1

I like to use these tables when a set of data doesn't change very often, but still needs to be enumerated from time to time.

Hope this helps!

There's a static method in ToolStripRenderer class, named CreateDisabledImage. Its usage is as simple as:

Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);

It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.

By default the Ant will considered the JRE as the workspace JRE version. You need to change according to your required version by following the below.

In Eclipse:

• Right click on your build.xml click "Run As", click on "External Tool Configurations..." Select tab JRE.

• Select the JRE you are using.

• Re-run the task, it should be fine now.

Another alternative:

No need to define 2 animation for fadeIn and fadeOut. fadeOut is reverse of fadeIn.

So you can do this with Animation.REVERSE like this:

AlphaAnimation alphaAnimation = new AlphaAnimation(0.0f, 1.0f);
alphaAnimation.setDuration(1000);
alphaAnimation.setRepeatCount(1);
alphaAnimation.setRepeatMode(Animation.REVERSE);
view.findViewById(R.id.imageview_logo).startAnimation(alphaAnimation);

then onAnimationEnd:

alphaAnimation.setAnimationListener(new Animation.AnimationListener() {
    @Override
        public void onAnimationStart(Animation animation) {
            //TODO: Run when animation start
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            //TODO: Run when animation end
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
            //TODO: Run when animation repeat
        }
    });

Everyone else has posted some perfectly reasonable answers. I took a different direction. Without using split, substring, or indexOf. Works great on i.e. and firefox. Probably works on Netscape too.

Just a loop and two ifs.

function getAfterDash(str) {
    var dashed = false;
    var result = "";
    for (var i = 0, len = str.length; i < len; i++) {
        if (dashed) {
            result = result + str[i];
        }
        if (str[i] === '-') {
            dashed = true;
        }
    }
    return result;
};

console.log(getAfterDash("adfjkl-o812347"));

My solution is performant and handles edge cases.

The point of the above code was to procrastinate work, please don't actually use it.

I try to avoid TABLEs as much as possible, but when we are designing complex forms that mix multiple control types and different caption positions with pretty strict controls on grouping, using DIVs is unreliable or often near impossible.

Now, I will not argue that these forms could not be redesigned to better accommodate a DIV based layout, but for some of them our customer is adamant about not changing the existing layouts from the previous version (written in classic ASP) because it parallels a paper form that their users are familiar with.

Because the presentation of the forms is dynamic (where the display of some sections is based on the state of the case or the permissions of the user), we use sets of stacked DIVs, each containing a TABLE of logically grouped form elements. Each column of the TABLE is classed so that they can be controlled by CSS. That way we can turn off different sections of the form without the problem of not being table to wrap rows in DIVs.

UPDATE: This changes in npm v7 due to npm RFC 21.

npm (and yarn) passes a lot of data from package.json into scripts as environment variables. Use npm run env to see them all. This is documented in https://docs.npmjs.com/misc/scripts#environment and is not only for "lifecycle" scripts like prepublish but also any script executed by npm run.

You can access these inside code (e.g. process.env.npm_package_config_port in JS) but they're already available to the shell running the scripts so you can also access them as $npm_... expansions in the "scripts" (unix syntax, might not work on windows?).

The "config" section seems intended for this use:

  "name": "myproject",
  ...
  "config": {
    "port": "8010"
  },
  "scripts": {
    "start": "node server.js $npm_package_config_port",
    "test": "wait-on http://localhost:$npm_package_config_port/ && node test.js http://localhost:$npm_package_config_port/"
  } 

An important quality of these "config" fields is that users can override them without modifying package.json!

$ npm run start

> [email protected] start /home/cben/mydir
> node server.js $npm_package_config_port

Serving on localhost:8010

$ npm config set myproject:port 8020
$ git diff package.json  # no change!
$ cat ~/.npmrc
myproject:port=8020

$ npm run start

> [email protected] start /home/cben/mydir
> node server.js $npm_package_config_port

Serving on localhost:8020

See npm config and yarn config docs.
It appears that yarn reads ~/.npmrc so npm config set affects both, but yarn config set writes to ~/.yarnrc, so only yarn will see it :-(

Use FirstOrDefault insted of SingleOrDefault..

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

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

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

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

The two main differences are:

• when you capture even a single argument, you are able to make much more elaborate tests on this argument, and with more obvious code;
• an ArgumentCaptor can capture more than once.

To illustrate the latter, say you have:

final ArgumentCaptor<Foo> captor = ArgumentCaptor.forClass(Foo.class);

verify(x, times(4)).someMethod(captor.capture()); // for instance

Then the captor will be able to give you access to all 4 arguments, which you can then perform assertions on separately.

This or any number of arguments in fact, since a VerificationMode is not limited to a fixed number of invocations; in any event, the captor will give you access to all of them, if you wish.

This also has the benefit that such tests are (imho) much easier to write than having to implement your own ArgumentMatchers -- particularly if you combine mockito with assertj.

Oh, and please consider using TestNG instead of JUnit.

You can also remove the line

  require: 'ngModel',

if you don't need ngModel in this directive. Removing ngModel will allow you to make a directive without thatngModel error.

The error usually means that the port you are trying to open is being already used by another application. Try using netstat to see which ports are open and then use an available port.

Also check if you are binding to the right ip address (I am assuming it would be localhost)

It's quite easy and efficient to use Excel as a reporting tool for Access data. A quick "non programming" approach is to set a List or a Pivot Table, linked to your External Data source. But that's out of scope for Stackoverflow.
A programmatic approach can be very simple:

strProv = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & SourceFile & ";"
Set cnn = New ADODB.Connection  
cnn.Open strProv
Set rst = New ADODB.Recordset
rst.Open strSql, cnn
myDestRange.CopyFromRecordset rst

That's it !

Try with this

Response.Clear();
Response.AppendHeader("Content-Type", "application/vnd.openxmlformats-officedocument.presentationml.presentation");
Response.AppendHeader("Content-Disposition", string.Format("attachment;filename={0}.pptx;", getLegalFileName(CurrentPresentation.Presentation_NM)));
Response.Flush();                
Response.BinaryWrite(masterPresentation.ToArray());
Response.End();

simple google search turned up this:

If the data is actually an HTML page and has NOT been created by ASP, PHP, or some other scripting language, and you are using Internet Explorer 6, and you have Excel installed on your computer, simply right-click on the page and look through the menu. You should see "Export to Microsoft Excel." If all these conditions are true, click on the menu item and after a few prompts it will be imported to Excel.

if you can't do that, he gives an alternate "drag-and-drop" method:

.textbox {

}

<div id=signin>  
    <input type="text" class="textbox" size="25%" height="50"/></br>
<input type="text" class="textbox" size="25%" height="50"/>

Make the font size larger and add height (or line height to the input boxes) I would not recommend adding those size and height attributes in the HTML as that can be handled by CSS. I have made a class text-box that can be used for multiple input boxes

As of November 2020, in order to show one figure at a time, the following works:

import matplotlib.pyplot as plt

f1, ax1 = plt.subplots()
ax1.plot(range(0,10))
f1.show()
input("Close the figure and press a key to continue")
f2, ax2 = plt.subplots()
ax2.plot(range(10,20))
f2.show()
input("Close the figure and press a key to continue")

The call to input() prevents the figure from opening and closing immediately.

Your data structure and your JSON do not match.

Your JSON is this:

{
    "JsonValues":{
        "id": "MyID",
        ...
    }
}

But the data structure you try to serialize it to is this:

class ValueSet
{
    [JsonProperty("id")]
    public string id
    {
        get;
        set;
    }
    ...
}

You are skipping a step: Your JSON is a class that has one property named JsonValues, which has an object of your ValueSet data structure as value.

Also inside your class your JSON is this:

"values": { ... }

Your data structure is this:

[JsonProperty("values")]
public List<Value> values
{
    get;
    set;
}

Note that { .. } in JSON defines an object, where as [ .. ] defines an array. So according to your JSON you don't have a bunch of values, but you have one values object with the properties value1 and value2 of type Value.

Since the deserializer expects an array but gets an object instead, it does the least non-destructive (Exception) thing it could do: skip the value. Your property values remains with it's default value: null.

If you can: Adjust your JSON. The following would match your data structure and is most likely what you actually want:

{
    "id": "MyID",

     "values": [
         {
            "id": "100",
            "diaplayName": "MyValue1"
         }, {
            "id": "200",
            "diaplayName": "MyValue2"
         }
     ]
}

With Swift 5, you can choose one of the two following Playground code samples in order to animate your UILabel's text changes with some cross dissolve animation.

#1. Using UIView's transition(with:duration:options:animations:completion:) class method

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let label = UILabel()

    override func viewDidLoad() {
        super.viewDidLoad()

        label.text = "Car"

        view.backgroundColor = .white
        view.addSubview(label)

        label.translatesAutoresizingMaskIntoConstraints = false
        label.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        label.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(toggle(_:)))
        view.addGestureRecognizer(tapGesture)
    }

    @objc func toggle(_ sender: UITapGestureRecognizer) {
        let animation = {
            self.label.text = self.label.text == "Car" ? "Plane" : "Car"
        }
        UIView.transition(with: label, duration: 2, options: .transitionCrossDissolve, animations: animation, completion: nil)
    }

}

let controller = ViewController()
PlaygroundPage.current.liveView = controller

#2. Using CATransition and CALayer's add(_:forKey:) method

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let label = UILabel()
    let animation = CATransition()

    override func viewDidLoad() {
        super.viewDidLoad()

        label.text = "Car"

        animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        // animation.type = CATransitionType.fade // default is fade
        animation.duration = 2

        view.backgroundColor = .white
        view.addSubview(label)

        label.translatesAutoresizingMaskIntoConstraints = false
        label.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        label.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(toggle(_:)))
        view.addGestureRecognizer(tapGesture)
    }

    @objc func toggle(_ sender: UITapGestureRecognizer) {
        label.layer.add(animation, forKey: nil) // The special key kCATransition is automatically used for transition animations
        label.text = label.text == "Car" ? "Plane" : "Car"
    }

}

let controller = ViewController()
PlaygroundPage.current.liveView = controller

Introduction

Whenever an UICommand component (<h:commandXxx>, <p:commandXxx>, etc) fails to invoke the associated action method, or an UIInput component (<h:inputXxx>, <p:inputXxxx>, etc) fails to process the submitted values and/or update the model values, and you aren't seeing any googlable exceptions and/or warnings in the server log, also not when you configure an ajax exception handler as per Exception handling in JSF ajax requests, nor when you set below context parameter in web.xml,

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

and you are also not seeing any googlable errors and/or warnings in browser's JavaScript console (press F12 in Chrome/Firefox23+/IE9+ to open the web developer toolset and then open the Console tab), then work through below list of possible causes.

Possible causes

1. UICommand and UIInput components must be placed inside an UIForm component, e.g. <h:form> (and thus not plain HTML <form>), otherwise nothing can be sent to the server. UICommand components must also not have type="button" attribute, otherwise it will be a dead button which is only useful for JavaScript onclick. See also How to send form input values and invoke a method in JSF bean and <h:commandButton> does not initiate a postback.

2. You cannot nest multiple UIForm components in each other. This is illegal in HTML. The browser behavior is unspecified. Watch out with include files! You can use UIForm components in parallel, but they won't process each other during submit. You should also watch out with "God Form" antipattern; make sure that you don't unintentionally process/validate all other (invisible) inputs in the very same form (e.g. having a hidden dialog with required inputs in the very same form). See also How to use <h:form> in JSF page? Single form? Multiple forms? Nested forms?.

3. No UIInput value validation/conversion error should have occurred. You can use <h:messages> to show any messages which are not shown by any input-specific <h:message> components. Don't forget to include the id of <h:messages> in the <f:ajax render>, if any, so that it will be updated as well on ajax requests. See also h:messages does not display messages when p:commandButton is pressed.

4. If UICommand or UIInput components are placed inside an iterating component like <h:dataTable>, <ui:repeat>, etc, then you need to ensure that exactly the same value of the iterating component is been preserved during the apply request values phase of the form submit request. JSF will reiterate over it to find the clicked link/button and submitted input values. Putting the bean in the view scope and/or making sure that you load the data model in @PostConstruct of the bean (and thus not in a getter method!) should fix it. See also How and when should I load the model from database for h:dataTable.

5. If UICommand or UIInput components are included by a dynamic source such as <ui:include src="#{bean.include}">, then you need to ensure that exactly the same #{bean.include} value is preserved during the view build time of the form submit request. JSF will reexecute it during building the component tree. Putting the bean in the view scope and/or making sure that you load the data model in @PostConstruct of the bean (and thus not in a getter method!) should fix it. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

6. The rendered attribute of the component and all of its parents and the test attribute of any parent <c:if>/<c:when> should not evaluate to false during the apply request values phase of the form submit request. JSF will recheck it as part of safeguard against tampered/hacked requests. Storing the variables responsible for the condition in a @ViewScoped bean or making sure that you're properly preinitializing the condition in @PostConstruct of a @RequestScoped bean should fix it. The same applies to the disabled and readonly attributes of the component, which should not evaluate to true during apply request values phase. See also JSF CommandButton action not invoked, Form submit in conditionally rendered component is not processed, h:commandButton is not working once I wrap it in a <h:panelGroup rendered> and Force JSF to process, validate and update readonly/disabled input components anyway

7. The onclick attribute of the UICommand component and the onsubmit attribute of the UIForm component should not return false or cause a JavaScript error. There should in case of <h:commandLink> or <f:ajax> also be no JS errors visible in the browser's JS console. Usually googling the exact error message will already give you the answer. See also Manually adding / loading jQuery with PrimeFaces results in Uncaught TypeErrors.

8. If you're using Ajax via JSF 2.x <f:ajax> or e.g. PrimeFaces <p:commandXxx>, make sure that you have a <h:head> in the master template instead of the <head>. Otherwise JSF won't be able to auto-include the necessary JavaScript files which contains the Ajax functions. This would result in a JavaScript error like "mojarra is not defined" or "PrimeFaces is not defined" in browser's JS console. See also h:commandLink actionlistener is not invoked when used with f:ajax and ui:repeat.

9. If you're using Ajax, and the submitted values end up being null, then make sure that the UIInput and UICommand components of interest are covered by the <f:ajax execute> or e.g. <p:commandXxx process>, otherwise they won't be executed/processed. See also Submitted form values not updated in model when adding <f:ajax> to <h:commandButton> and Understanding PrimeFaces process/update and JSF f:ajax execute/render attributes.

10. If the submitted values still end up being null, and you're using CDI to manage beans, then make sure that you import the scope annotation from the correct package, else CDI will default to @Dependent which effectively recreates the bean on every single evaluation of the EL expression. See also @SessionScoped bean looses scope and gets recreated all the time, fields become null and What is the default Managed Bean Scope in a JSF 2 application?

11. If a parent of the <h:form> with the UICommand button is beforehand been rendered/updated by an ajax request coming from another form in the same page, then the first action will always fail in JSF 2.2 or older. The second and subsequent actions will work. This is caused by a bug in view state handling which is reported as JSF spec issue 790 and currently fixed in JSF 2.3. For older JSF versions, you need to explicitly specify the ID of the <h:form> in the render of the <f:ajax>. See also h:commandButton/h:commandLink does not work on first click, works only on second click.

12. If the <h:form> has enctype="multipart/form-data" set in order to support file uploading, then you need to make sure that you're using at least JSF 2.2, or that the servlet filter who is responsible for parsing multipart/form-data requests is properly configured, otherwise the FacesServlet will end up getting no request parameters at all and thus not be able to apply the request values. How to configure such a filter depends on the file upload component being used. For Tomahawk <t:inputFileUpload>, check this answer and for PrimeFaces <p:fileUpload>, check this answer. Or, if you're actually not uploading a file at all, then remove the attribute altogether.

13. Make sure that the ActionEvent argument of actionListener is an javax.faces.event.ActionEvent and thus not java.awt.event.ActionEvent, which is what most IDEs suggest as 1st autocomplete option. Having no argument is wrong as well if you use actionListener="#{bean.method}". If you don't want an argument in your method, use actionListener="#{bean.method()}". Or perhaps you actually want to use action instead of actionListener. See also Differences between action and actionListener.

14. Make sure that no PhaseListener or any EventListener in the request-response chain has changed the JSF lifecycle to skip the invoke action phase by for example calling FacesContext#renderResponse() or FacesContext#responseComplete().

15. Make sure that no Filter or Servlet in the same request-response chain has blocked the request fo the FacesServlet somehow. For example, login/security filters such as Spring Security. Particularly in ajax requests that would by default end up with no UI feedback at all. See also Spring Security 4 and PrimeFaces 5 AJAX request handling.

16. If you are using a PrimeFaces <p:dialog> or a <p:overlayPanel>, then make sure that they have their own <h:form>. Because, these components are by default by JavaScript relocated to end of HTML <body>. So, if they were originally sitting inside a <form>, then they would now not anymore sit in a <form>. See also p:commandbutton action doesn't work inside p:dialog

17. Bug in the framework. For example, RichFaces has a "conversion error" when using a rich:calendar UI element with a defaultLabel attribute (or, in some cases, a rich:placeholder sub-element). This bug prevents the bean method from being invoked when no value is set for the calendar date. Tracing framework bugs can be accomplished by starting with a simple working example and building the page back up until the bug is discovered.

Debugging hints

In case you still stucks, it's time to debug. In the client side, press F12 in webbrowser to open the web developer toolset. Click the Console tab so see the JavaScript conosle. It should be free of any JavaScript errors. Below screenshot is an example from Chrome which demonstrates the case of submitting an <f:ajax> enabled button while not having <h:head> declared (as described in point 7 above).

Click the Network tab to see the HTTP traffic monitor. Submit the form and investigate if the request headers and form data and the response body are as per expectations. Below screenshot is an example from Chrome which demonstrates a successful ajax submit of a simple form with a single <h:inputText> and a single <h:commandButton> with <f:ajax execute="@form" render="@form">.

(warning: when you post screenshots from HTTP request headers like above from a production environment, then make sure you scramble/obfuscate any session cookies in the screenshot to avoid session hijacking attacks!)

In the server side, make sure that server is started in debug mode. Put a debug breakpoint in a method of the JSF component of interest which you expect to be called during processing the form submit. E.g. in case of UICommand component, that would be UICommand#queueEvent() and in case of UIInput component, that would be UIInput#validate(). Just step through the code execution and inspect if the flow and variables are as per expectations. Below screenshot is an example from Eclipse's debugger.

Visual Studio Code has excellent search and replace capabilities across files. It is extremely fast, supports regex and live preview before replacement.

After you create image, check it with:

$ docker inspect $image_name 

and check what you have in CMD option. For busy box it should be:

"Cmd": [
     "/bin/sh"
]

Maybe you are overwritting CMD option in your ./mkimage.sh

Additionally to the solutions that were suggested in sibling comments, you may change your testing approach a little bit and test not the whole page all at once (with a deep children components tree), but do an isolated component testing. This will simplify testing of onClick() and similar events (see example below).

The idea is to test only one component at a time and not all of them together. In this case all children components will be mocked using the jest.mock() function.

Here is an example of how the onClick() event may be tested in an isolated SearchForm component using Jest and react-test-renderer.

import React from 'react';
import renderer from 'react-test-renderer';
import { SearchForm } from '../SearchForm';

describe('SearchForm', () => {
  it('should fire onSubmit form callback', () => {
    // Mock search form parameters.
    const searchQuery = 'kittens';
    const onSubmit = jest.fn();

    // Create test component instance.
    const testComponentInstance = renderer.create((
      <SearchForm query={searchQuery} onSearchSubmit={onSubmit} />
    )).root;

    // Try to find submit button inside the form.
    const submitButtonInstance = testComponentInstance.findByProps({
      type: 'submit',
    });
    expect(submitButtonInstance).toBeDefined();

    // Since we're not going to test the button component itself
    // we may just simulate its onClick event manually.
    const eventMock = { preventDefault: jest.fn() };
    submitButtonInstance.props.onClick(eventMock);

    expect(onSubmit).toHaveBeenCalledTimes(1);
    expect(onSubmit).toHaveBeenCalledWith(searchQuery);
  });
});

Another option is to open the terminal at the pycharm & install it with pip

sudo pip install numpy

You can vertically align a floated element in a way which works on IE 6+. It doesn't need full table markup either. This method isn't perfectly clean - includes wrappers and there are a few things to be aware of e.g. if you have too much text outspilling the container - but it's pretty good.

Short answer: You just need to apply display: table-cell to an element inside the floated element (table cells don't float), and use a fallback with position: absolute and top for old IE.

Long answer: Here's a jsfiddle showing the basics. The important stuff summarized (with a conditional comment adding an .old-ie class):

    .wrap {
        float: left;
        height: 100px; /* any fixed amount */
    }
    .wrap2 {
        height: inherit;
    }
    .content {
        display: table-cell;
        height: inherit;
        vertical-align: middle;
    }

    .old-ie .wrap{
        position: relative;
    }
    .old-ie .wrap2 {
        position: absolute;
        top: 50%;
    }
    .old-ie .content {
        position: relative;
        top: -50%;
        display: block;
    }

Here's a jsfiddle that deliberately highlight the minor faults with this method. Note how:

• In standards browsers, content that exceeds the height of the wrapper element stops centering and starts going down the page. This isn't a big problem (probably looks better than creeping up the page), and can be avoided by avoiding content that is too big (note that unless I've overlooked something, overflow methods like overflow: auto; don't seem to work)
• In old IE, the content element doesn't stretch to fill the available space - the height is the height of the content, not of the container.

Those are pretty minor limitations, but worth being aware of.

Code and idea adapted from here

Also in IOS if you want to get rid of gray semi-transparent overlays appearing ontouch, add css:

-webkit-tap-highlight-color: rgba(0,0,0,0);
-webkit-touch-callout: none;

I have a list of color names in range A2:A8, in column B I want to extract a distinct list of color names.

Follow the below given steps:

• Select the Cell B2; write the formula to retrieve the unique values from a list.
• =IF(COUNTIF(A$2:A2,A2)=1,A2,””)
• Press Enter on your keyboard.
• The function will return the name of the first color.
• To return the value for the rest of cells, copy the same formula down. To copy formula in range B3:B8, copy the formula in cell B2 by pressing the key CTRL+C on your keyboard and paste in the range B3:B8 by pressing the key CTRL+V.
• Here you can see the output where we have the unique list of color names.

I thought JSON.parse(myObject) would work. But depending on the browsers, it might be worth using eval('('+myObject+')'). The only issue I can recommend watching out for is the multi-level list in JSON.

try this, calling the activity in the constructor

public class WebService {
private Activity activity;

        public WebService(Activity _activity){
            activity=_activity;
            helper=new Helper(activity);

        }
}

var jArr = [
{
    id : "001",
    name : "apple",
    category : "fruit",
    color : "red"
},
{
    id : "002",
    name : "melon",
    category : "fruit",
    color : "green"
},
{
    id : "003",
    name : "banana",
    category : "fruit",
    color : "yellow"
}
]

var tableData = '<table><tr><td>Id</td><td>Name</td><td>Category</td><td>Color</td></tr>';
$.each(jArr, function(index, data) {
 tableData += '<tr><td>'+data.id+'</td><td>'+data.name+'</td><td>'+data.category+'</td><td>'+data.color+'</td></tr>';
});

$('div').html(tableData);

According to the spec for locating Schemas

there may or may not be a schema retrievable via the namespace name... User community and/or consumer/provider agreements may establish circumstances in which [trying to retrieve an xsd from the namespace url] is a sensible default strategy

(thanks for being unambiguous, spec!)

and

in case a document author (human or not) created a document with a particular schema in view, and warrants that some or all of the document conforms to that schema, the schemaLocation and noNamespaceSchemaLocation [attributes] are provided.

So basically with specifying just a namespace, your XML "might" be attempted to be validated against an xsd at that location (even if it lacks a schemaLocation attribute), depending on your "community." If you specify a specific schemaLocation, then it basically is implying that the xml document "should" be conformant to said xsd, so "please validate it" (as I read it). My guess is that if you don't do a schemaLocation or noNamespaceSchemaLocation attribute it just "isn't validated" most of the time (based on the other answers, appears java does it this way).

Another wrinkle here is that typically, with xsd validation in java libraries [ex: spring config xml files], if your XML files specifies a particular schemaLocation xsd url in an XML file, like xsi:schemaLocation="http://somewhere http://somewhere/something.xsd" typically within one of your dependency jars it will contain a copy of that xsd file, in its resources section, and spring has a "mapping" capability saying to treat that xsd file as if it maps to the url http://somewhere/something.xsd (so you never end up going to web and downloading the file, it just exists locally). See also https://stackoverflow.com/a/41225329/32453 for slightly more info.

As mentioned in have debugger run application as different user (linked above), another extremely simple way to do this which doesn't require any more tools:

• Hold Shift + right-click to open a new instance of Visual Studio.

• Click "Run as different user"

  

• Enter credentials of the other user in the next pop-up window

• Open the same solution you are working with

Now when you debug the solution it will be with the other user's permissions.

Hint: if you are going to run multiple instances of Visual Studio, change the theme of it (like to "dark") so you can keep track of which one is which easily).

As of ES 7, mapping types have been removed. You can read more details here

If you are using Ruby On Rails this means that you may need to remove document_type from your model or concern.

As an alternative to mapping types one solution is to use an index per document type.

Before:

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
    document_type self.name.downcase
  end
end

After:

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
  end
end

This may work for those of us who use different os/systems, but want to get the best of all worlds:

import os
workers = os.cpu_count()
if 'sched_getaffinity' in dir(os):
    workers = len(os.sched_getaffinity(0))

Normally, it should work.

But can you try this? I don't have SQL on my home PC, I can't try myself

UPDATE table
SET EndDate = '2009-05-25 00:00:00.000'
WHERE Id = 1

PUT is meant as a a method for "uploading" stuff to a particular URI, or overwriting what is already in that URI.

POST, on the other hand, is a way of submitting data RELATED to a given URI.

Refer to the HTTP RFC

Try this on for size:

String properCase (String inputVal) {
    // Empty strings should be returned as-is.

    if (inputVal.length() == 0) return "";

    // Strings with only one character uppercased.

    if (inputVal.length() == 1) return inputVal.toUpperCase();

    // Otherwise uppercase first letter, lowercase the rest.

    return inputVal.substring(0,1).toUpperCase()
        + inputVal.substring(1).toLowerCase();
}

It basically handles special cases of empty and one-character string first and correctly cases a two-plus-character string otherwise. And, as pointed out in a comment, the one-character special case isn't needed for functionality but I still prefer to be explicit, especially if it results in fewer useless calls, such as substring to get an empty string, lower-casing it, then appending it as well.

Press the Esc key to make sure your are not in an edit mode. Place the cursor on the first line to be deleted. Enter :5dd. The current line, and the next four lines should be deleted.

Alternately, if you have line numbering turned on...

Press the Esc key to make sure your are not in an edit mode. Enter :#,#d where '#' stands for the beginning and ending line numbers to be deleted.

You must have some virtual function declared in one of the parent classes and never implemented in any of the child classes. Make sure that all virtual functions are implemented somewhere in the inheritence chain. If a class's definition includes a pure virtual function that is never implemented, an instance of that class cannot ever be constructed.

Try this:

function explode(){
  alert("Boom!");
}
setTimeout(explode, 2000);

Updated Answer

^{* Updated answer which support the v2.1.1** bootstrap version stylesheet.}

^{**But be careful because this solution has been removed from v3}

Just wanted to point out that this solution is not needed anymore as the latest bootstrap now supports multi-level dropdowns by default. You can still use it if you're on older versions but for those who updated to the latest (v2.1.1 at the time of writing) it is not needed anymore. Here is a fiddle with the updated default multi-level dropdown straight from the documentation:

http://jsfiddle.net/2Smgv/2858/

Original Answer

There have been some issues raised on submenu support over at github and they are usually closed by the bootstrap developers, such as this one, so i think it is left to the developers using the bootstrap to work something out. Here is a demo i put together showing you how you can hack together a working sub-menu.

Relevant code

CSS

.dropdown-menu .sub-menu {
    left: 100%;
    position: absolute;
    top: 0;
    visibility: hidden;
    margin-top: -1px;
}

.dropdown-menu li:hover .sub-menu {
    visibility: visible;
    display: block;
}

.navbar .sub-menu:before {
    border-bottom: 7px solid transparent;
    border-left: none;
    border-right: 7px solid rgba(0, 0, 0, 0.2);
    border-top: 7px solid transparent;
    left: -7px;
    top: 10px;
}
.navbar .sub-menu:after {
    border-top: 6px solid transparent;
    border-left: none;
    border-right: 6px solid #fff;
    border-bottom: 6px solid transparent;
    left: 10px;
    top: 11px;
    left: -6px;
}

Created my own .sub-menu class to apply to the 2-level drop down menus, this way we can position them next to our menu items. Also modified the arrow to display it on the left of the submenu group.

Demo

There are always problems with Googles "oh so great" support libs. If you want to check an item without downgrading your support libs version, just set checkable before setting checked state.

MenuItem item = drawer.getMenu().findItem(R.id.action_something);
item.setCheckable(true);
item.setChecked(true);

It might also work if you set checkable in the menu xml files

My solution:

Change back to bash:

source .bashrc

next:

echo $PATH

copy this:

/home/frank/.asdf/shims:/home/frank/....

back to the zsh:

source .zsh

open .zshrc:

and paste:

 export PATH=/home/frank/.asdf/shims:/home/frank/....

restart terminal

I think you've pretty much nailed the points!

If you follow database design best practices and your primary key is never updatable (which I think should always be the case anyway), then you never really need the ON UPDATE CASCADE clause.

Zed made a good point, that if you use a natural key (e.g. a regular field from your database table) as your primary key, then there might be certain situations where you need to update your primary keys. Another recent example would be the ISBN (International Standard Book Numbers) which changed from 10 to 13 digits+characters not too long ago.

This is not the case if you choose to use surrogate (e.g. artifically system-generated) keys as your primary key (which would be my preferred choice in all but the most rare occasions).

So in the end: if your primary key never changes, then you never need the ON UPDATE CASCADE clause.

Marc

Have you considered letting the user of your application select their own color scheme? Without fail you won't be able to please all of your users with your selection but you can allow them to find what pleases them.

You can also access a column using the dot notation (also called attribute access) and then calculate its mean:

df.your_column_name.mean()

Was having an issue getting the "Run in Postman" links to work with the browsers until I added this to the .desktop file

MimeType=application/postman;x-scheme-handler/postman;

You can easily write the method to do that :

  public static String toCamelCase(final String init) {
    if (init == null)
        return null;

    final StringBuilder ret = new StringBuilder(init.length());

    for (final String word : init.split(" ")) {
        if (!word.isEmpty()) {
            ret.append(Character.toUpperCase(word.charAt(0)));
            ret.append(word.substring(1).toLowerCase());
        }
        if (!(ret.length() == init.length()))
            ret.append(" ");
    }

    return ret.toString();
}

The answers referring to simply calling array() are not quite correct: when the buffer has been partially consumed, or is referring to a part of an array (you can ByteBuffer.wrap an array at a given offset, not necessarily from the beginning), we have to account for that in our calculations. This is the general solution that works for buffers in all cases (does not cover encoding):

if (myByteBuffer.hasArray()) {
    return new String(myByteBuffer.array(),
        myByteBuffer.arrayOffset() + myByteBuffer.position(),
        myByteBuffer.remaining());
} else {
    final byte[] b = new byte[myByteBuffer.remaining()];
    myByteBuffer.duplicate().get(b);
    return new String(b);
}

For the concerns related to encoding, see Andy Thomas' answer.

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

Which whitespace character? The empty string is pretty unambiguous - it's a sequence of 0 characters. However, " ", "\t" and "\n" are all strings containing a single character which is characterized as whitespace.

If you just mean a space, use a space. If you mean some other whitespace character, there may well be a custom escape sequence for it (e.g. "\t" for tab) or you can use a Unicode escape sequence ("\uxxxx"). I would discourage you from including non-ASCII characters in your source code, particularly whitespace ones.

EDIT: Now that you've explained what you want to do (which should have been in your question to start with) you'd be better off using Regex.Split with a regular expression of \s which represents whitespace:

Regex regex = new Regex(@"\s");
string[] bits = regex.Split(text.ToLower());

See the Regex Character Classes documentation for more information on other character classes.

You do need to loop through it. C++ does not implement any simpler way to do this when you are dealing with primitive type arrays.

I've written an extension class to help me deserializing from JSON sources (string, stream, file).

public static class JsonHelpers
{
    public static T CreateFromJsonStream<T>(this Stream stream)
    {
        JsonSerializer serializer = new JsonSerializer();
        T data;
        using (StreamReader streamReader = new StreamReader(stream))
        {
            data = (T)serializer.Deserialize(streamReader, typeof(T));
        }
        return data;
    }

    public static T CreateFromJsonString<T>(this String json)
    {
        T data;
        using (MemoryStream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(json)))
        {
            data = CreateFromJsonStream<T>(stream);
        }
        return data;
    }

    public static T CreateFromJsonFile<T>(this String fileName)
    {
        T data;
        using (FileStream fileStream = new FileStream(fileName, FileMode.Open))
        {
            data = CreateFromJsonStream<T>(fileStream);
        }
        return data;
    }
}

Deserializing is now as easy as writing:

MyType obj1 = aStream.CreateFromJsonStream<MyType>();
MyType obj2 = "{\"key\":\"value\"}".CreateFromJsonString<MyType>();
MyType obj3 = "data.json".CreateFromJsonFile<MyType>();

Hope it will help someone else.

If you start Notepad and then File -> Save As -> Write .htaccess and choose "All Files" as the type - then it will create the .htaccess file for you.

User1's example worked well for me. But, as a warning, it won't work with anything other than simple String/Integer types, unless you add an @XmlSeeAlso annotation:

@XmlRootElement(name = "List")
@XmlSeeAlso(MovieTicket.class)
public class MovieTicketList {
    protected List<MovieTicket> list;

This works OK, although it prevents me from using a single generic list class across my entire application. It might also explain why this seemingly obvious class doesn't exist in the JAXB package.

If you want to be secure use this:<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

1. Run your app on the simulator, and save screen shots.

2. Rename those screen shots to 4.7.1 (iPhone 6), 5.5.1 (iPhone 6 plus) and so on.

There are many possibilities to do this in R. Here are some of them:

df <- read.table(header = TRUE, text = 'Gene   Value
A      12
A      10
B      3
B      5
B      6
C      1
D      3
D      4')

# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)

# tapply
tapply(df$Value, df$Gene, max)

# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))

# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))

# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))

# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]

# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)

# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')

# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]

You can use following:

    protected void Application_Start(object sender, EventArgs e)
    {
        ThreadPool.QueueUserWorkItem(new WaitCallback(StartMySystem));
    }

    private void StartMySystem(object state)
    {
        Log(HttpContext.Current.Request.ToString());
    }

If you are planning on using your Swift singleton class in Objective-C, this setup will have the compiler generate appropriate Objective-C-like header(s):

class func sharedStore() -> ImageStore {
struct Static {
    static let instance : ImageStore = ImageStore()
    }
    return Static.instance
}

Then in Objective-C class you can call your singleton the way you did it in pre-Swift days:

[ImageStore sharedStore];

This is just my simple implementation.

Improved version of what Ustaman Sangat did

    return val;
}

A simple solution that works for me, to work with console ability(ReadKey, String with Format and arg etc) and to see and save the output:

I write TextWriter that write to Console and to Trace and replace the Console.Out with it.

if you use Dialog -> Debugging -> Check the "Redirect All Output Window Text to the Immediate Window" you get it in the Immediate Window and pretty clean.

my code: in start of my code:

Console.SetOut(new TextHelper());

and the class:

public class TextHelper : TextWriter
{
    TextWriter console;

    public TextHelper() {
        console = Console.Out;
    }

    public override Encoding Encoding => this.console.Encoding;

    public override void WriteLine(string format, params object[] arg)
    {
        string s = string.Format(format, arg);
        WriteLine(s);
    }

    public override void Write(object value)
    {
        console.Write(value);
        System.Diagnostics.Trace.Write(value);
    }

    public override void WriteLine(object value)
    {
        Write(value);
        Write("\n");
    }

    public override void WriteLine(string value)
    {
        console.WriteLine(value);
        System.Diagnostics.Trace.WriteLine(value);
    }
}

Note: I override just what I needed so if you write other types you should override more

FORFILES /S /D -10 /C "cmd /c IF @isdir == TRUE rd /S /Q @path"

I could not get Blorgbeard's suggestion to work, but I was able to get it to work with RMDIR instead of RD:

FORFILES /p N:\test /S /D -10 /C "cmd /c IF @isdir == TRUE RMDIR /S /Q @path"

Since RMDIR won't delete folders that aren't empty so I also ended up using this code to delete the files that were over 10 days and then the folders that were over 10 days old.

FOR /d %%K in ("n:\test*") DO (

FOR /d %%J in ("%%K*") DO (

FORFILES /P %%J /S /M . /D -10 /C "cmd /c del @file"

)

)

FORFILES /p N:\test /S /D -10 /C "cmd /c IF @isdir == TRUE RMDIR /S /Q @path"

I used this code to purge out the sub folders in the folders within test (example n:\test\abc\123 would get purged when empty, but n:\test\abc would not get purged

To be clear: The accepted answer is correct. Try it first. However, it may be unnecessarily complex for some use cases, particularly if you encounter obnoxious errors such as 'fatal: bad revision --prune-empty', or really don't care about the history of your repo.

An alternative would be:

1. cd to project's base branch
2. Remove the sensitive code / file
3. rm -rf .git/ # Remove all git info from your code
4. Go to github and delete your repository
5. Follow this guide to push your code to a new repository as you normally would - https://help.github.com/articles/adding-an-existing-project-to-github-using-the-command-line/

This will of course remove all commit history branches, and issues from both your github repo, and your local git repo. If this is unacceptable you will have to use an alternate approach.

Call this the nuclear option.

If the actual problem at hand is to concatenate two 1-D arrays vertically, and we are not fixated on using concatenate to perform this operation, I would suggest the use of np.column_stack:

In []: a = np.array([1,2,3])
In []: b = np.array([4,5,6])
In []: np.column_stack((a, b))
array([[1, 4],
       [2, 5],
       [3, 6]])

Even though it's an old question, I still had some hard time with fetching dynamic variables names, while avoiding the eval (evil) command.

Solved it with declare -n which creates a reference to a dynamic value, this is especially useful in CI/CD processes, where the required secret names of the CI/CD service are not known until runtime. Here's how:

# Bash v4.3+
# -----------------------------------------------------------
# Secerts in CI/CD service, injected as environment variables
# AWS_ACCESS_KEY_ID_DEV, AWS_SECRET_ACCESS_KEY_DEV
# AWS_ACCESS_KEY_ID_STG, AWS_SECRET_ACCESS_KEY_STG
# -----------------------------------------------------------
# Environment variables injected by CI/CD service
# BRANCH_NAME="DEV"
# -----------------------------------------------------------
declare -n _AWS_ACCESS_KEY_ID_REF=AWS_ACCESS_KEY_ID_${BRANCH_NAME}
declare -n _AWS_SECRET_ACCESS_KEY_REF=AWS_SECRET_ACCESS_KEY_${BRANCH_NAME}

export AWS_ACCESS_KEY_ID=${_AWS_ACCESS_KEY_ID_REF}
export AWS_SECRET_ACCESS_KEY=${_AWS_SECRET_ACCESS_KEY_REF}

echo $AWS_ACCESS_KEY_ID $AWS_SECRET_ACCESS_KEY
aws s3 ls

There are two ways to do it.

1. In the method that opens the dialog, pass in the following configuration option disableClose as the second parameter in MatDialog#open() and set it to true:

   export class AppComponent {
     constructor(private dialog: MatDialog){}
     openDialog() {
       this.dialog.open(DialogComponent, { disableClose: true });
     }
   }
   

2. Alternatively, do it in the dialog component itself.

   export class DialogComponent {
     constructor(private dialogRef: MatDialogRef<DialogComponent>){
       dialogRef.disableClose = true;
     }
   }
   

Here's what you're looking for:

And here's a Stackblitz demo

Other use cases

Here's some other use cases and code snippets of how to implement them.

Allow esc to close the dialog but disallow clicking on the backdrop to close the dialog

As what @MarcBrazeau said in the comment below my answer, you can allow the esc key to close the modal but still disallow clicking outside the modal. Use this code on your dialog component:

import { Component, OnInit, HostListener } from '@angular/core';
import { MatDialogRef } from '@angular/material';
@Component({
  selector: 'app-third-dialog',
  templateUrl: './third-dialog.component.html'
})
export class ThirdDialogComponent {
  constructor(private dialogRef: MatDialogRef<ThirdDialogComponent>) {      
}
  @HostListener('window:keyup.esc') onKeyUp() {
    this.dialogRef.close();
  }

}

Prevent esc from closing the dialog but allow clicking on the backdrop to close

P.S. This is an answer which originated from this answer, where the demo was based on this answer.

To prevent the esc key from closing the dialog but allow clicking on the backdrop to close, I've adapted Marc's answer, as well as using MatDialogRef#backdropClick to listen for click events to the backdrop.

Initially, the dialog will have the configuration option disableClose set as true. This ensures that the esc keypress, as well as clicking on the backdrop will not cause the dialog to close.

Afterwards, subscribe to the MatDialogRef#backdropClick method (which emits when the backdrop gets clicked and returns as a MouseEvent).

Anyways, enough technical talk. Here's the code:

openDialog() {
  let dialogRef = this.dialog.open(DialogComponent, { disableClose: true });
  /*
     Subscribe to events emitted when the backdrop is clicked
     NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
     See https://stackoverflow.com/a/41086381 for more info
  */
  dialogRef.backdropClick().subscribe(() => {
    // Close the dialog
    dialogRef.close();
  })

  // ...
}

Alternatively, this can be done in the dialog component:

export class DialogComponent {
  constructor(private dialogRef: MatDialogRef<DialogComponent>) {
    dialogRef.disableClose = true;
    /*
      Subscribe to events emitted when the backdrop is clicked
      NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
      See https://stackoverflow.com/a/41086381 for more info
    */
    dialogRef.backdropClick().subscribe(() => {
      // Close the dialog
      dialogRef.close();
    })
  }
}

The dplyr select function selects specific columns from a data frame. To return unique values in a particular column of data, you can use the group_by function. For example:

library(dplyr)

# Fake data
set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE))

# Return the distinct values of x
dat %>%
  group_by(x) %>%
  summarise() 

    x
1   1
2   2
3   3
4   4
5   5
6   6
7   7
8   8
9   9
10 10

If you want to change the column name you can add the following:

dat %>%
  group_by(x) %>%
  summarise() %>%
  select(unique.x=x)

This both selects column x from among all the columns in the data frame that dplyr returns (and of course there's only one column in this case) and changes its name to unique.x.

You can also get the unique values directly in base R with unique(dat$x).

If you have multiple variables and want all unique combinations that appear in the data, you can generalize the above code as follows:

set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE), 
                 y=sample(letters[1:5], 100, replace=TRUE))

dat %>% 
  group_by(x,y) %>%
  summarise() %>%
  select(unique.x=x, unique.y=y)

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

Actually, wouldn't we want to do this?

import sys
sys.argv = ['abc.py','arg1', 'arg2']
execfile('abc.py')

Check your servers error log, typically /var/log/apache2/error.log.

@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000

If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:

...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'

or

...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06' 
   AND usagetime < '2012-09-03 08:03:07'

I think it will help you

string filename = String.Format("Results_{0}_{1}.xls", DateTime.Today.Month.ToString(), DateTime.Today.Year.ToString());
        if (!string.IsNullOrEmpty(GRIDVIEWNAME.Page.Title))
            filename = GRIDVIEWNAME.Page.Title + ".xls";

        HttpContext.Current.Response.Write(stringWriter.ToString());
        HttpContext.Current.Response.End();

we can use customized function or date pattern. Below code is customized function as per your requirement please change it.

 function isValidDate(str) {
        var getvalue = str.split('-');
        var day = getvalue[2];
        var month = getvalue[1];
        var year = getvalue[0];
        if(year < 1901 && year > 2100){
        return false;
        }
        if (month < 1 && month > 12) { 
          return false;
         }
         if (day < 1 && day > 31) {
          return false;
         }
         if ((month==4 && month==6 && month==9 && month==11) && day==31) {
          return false;
         }
         if (month == 2) { // check for february 29th
          var isleap = (year % 4 == 0 && (year % 100 != 0 || year % 400 == 0));
          if (day>29 || (day==29 && !isleap)) {
           return false;
         }
         }
         else{
         return true;

         }
        }

PHP arrays have internal pointers, so try this:

foreach($array as $key => $value){
   $index = current($array);
}

Works okay for me (only very preliminarily tested though).

tl;dr

Yes, you can... If a then a, else if b then if c then c(b), else b, else null

a ? a : (b ? (c ? c(b) : b) : null)

a
  ? a
  : b
      ? c
        ? c(b)
        : b
      : null

longer version

Ternary operator ?: used as inline if-else is right associative. In short this means that the rightmost ? gets fed first and it takes exactly one closest operand on the left and two, with a :, on the right.

Practically speaking, consider the following statement (same as above):

a ? a : b ? c ? c(b) : b : null

The rightmost ? gets fed first, so find it and its surrounding three arguments and consecutively expand to the left to another ?.

   a ? a : b ? c ? c(b) : b : null
                 ^                  <---- RTL
1.            |1-?-2----:-3|
             ^ <-
2.        |1-?|--2---------|:-3---|
     ^ <-
3.|1-?-2-:|--3--------------------|

result: a ? a : (b ? (c ? c(b) : b) : null)

This is how computers read it:

1. Term a is read.
   Node: a
2. Nonterminal ? is read.
   Node: a ?
3. Term a is read.
   Node: a ? a
4. Nonterminal : is read.
   Node: a ? a :
5. Term b is read.
   Node: a ? a : b
6. Nonterminal ? is read, triggering the right-associativity rule. Associativity decides:
   node: a ? a : (b ?
7. Term c is read.
   Node: a ? a : (b ? c
8. Nonterminal ? is read, re-applying the right-associativity rule.
   Node: a ? a : (b ? (c ?
9. Term c(b) is read.
   Node: a ? a : (b ? (c ? c(b)
10. Nonterminal : is read.
    Node: a ? a : (b ? (c ? c(b) :
11. Term b is read.
    Node: a ? a : (b ? (c ? c(b) : b
12. Nonterminal : is read. The ternary operator ?: from previous scope is satisfied and the scope is closed.
    Node: a ? a : (b ? (c ? c(b) : b) :
13. Term null is read.
    Node: a ? a : (b ? (c ? c(b) : b) : null
14. No tokens to read. Close remaining open parenthesis.
    #Result is: a ? a : (b ? (c ? c(b) : b) : null)

Better readability

The ugly oneliner from above could (and should) be rewritten for readability as:
(Note that the indentation does not implicitly define correct closures as brackets () do.)

a
  ? a
  : b
      ? c
        ? c(b)
        : b
      : null

for example

return a + some_lengthy_variable_name > another_variable
        ? "yep"
        : "nop"

from bower help, save option has a capital S

Because there is no pass-by-reference in the above code. Using pointers (such as void func(int* p)) is pass-by-address. This is pass-by-reference in C++ (won't work in C):

void func(int& ref) {ref = 4;}

...
int a;
func(a);
// a is 4 now

There isn't direct support for COUNT(DISTINCT {x})), but you can simulate it from an IGrouping<,> (i.e. what group by returns); I'm afraid I only "do" C#, so you'll have to translate to VB...

 select new
 {
     Foo= grp.Key,
     Bar= grp.Select(x => x.SomeField).Distinct().Count()
 };

Here's a Northwind example:

    using(var ctx = new DataClasses1DataContext())
    {
        ctx.Log = Console.Out; // log TSQL to console
        var qry = from cust in ctx.Customers
                  where cust.CustomerID != ""
                  group cust by cust.Country
                  into grp
                  select new
                  {
                      Country = grp.Key,
                      Count = grp.Select(x => x.City).Distinct().Count()
                  };

        foreach(var row in qry.OrderBy(x=>x.Country))
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }
    }

The TSQL isn't quite what we'd like, but it does the job:

SELECT [t1].[Country], (
    SELECT COUNT(*)
    FROM (
        SELECT DISTINCT [t2].[City]
        FROM [dbo].[Customers] AS [t2]
        WHERE ((([t1].[Country] IS NULL) AND ([t2].[Country] IS NULL)) OR (([t1]
.[Country] IS NOT NULL) AND ([t2].[Country] IS NOT NULL) AND ([t1].[Country] = [
t2].[Country]))) AND ([t2].[CustomerID] <> @p0)
        ) AS [t3]
    ) AS [Count]
FROM (
    SELECT [t0].[Country]
    FROM [dbo].[Customers] AS [t0]
    WHERE [t0].[CustomerID] <> @p0
    GROUP BY [t0].[Country]
    ) AS [t1]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

The results, however, are correct- verifyable by running it manually:

        const string sql = @"
SELECT c.Country, COUNT(DISTINCT c.City) AS [Count]
FROM Customers c
WHERE c.CustomerID != ''
GROUP BY c.Country
ORDER BY c.Country";
        var qry2 = ctx.ExecuteQuery<QueryResult>(sql);
        foreach(var row in qry2)
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }

With definition:

class QueryResult
{
    public string Country { get; set; }
    public int Count { get; set; }
}

This XPath:

count(//Property[long = '11007'])

returns the same value as:

count(//Property/long[text() = '11007'])

...except that the first counts Property nodes that match the criterion and the second counts long child nodes that match the criterion.

As per your comment and reading your question a couple of times, I believe that you want to find uniqueness based on a combination of criteria. Therefore, in actuality, I think you are actually checking multiple conditions. The following would work as well:

count(//Property[@Name = 'Alive'][long = '11007'])

because it means the same thing as:

count(//Property[@Name = 'Alive' and long = '11007'])

Of course, you would substitute the values for parameters in your template. The above code only illustrates the point.

EDIT (after question edit)

You were quite right about the XML being horrible. In fact, this is a downright CodingHorror candidate! I had to keep recounting to keep track of the "Property" node I was on presently. I feel your pain!

Here you go:

count(/root/ac/Properties/Property[Properties/Property/Properties/Property/long = $parPropId])

Note that I have removed all the other checks (for ID and Value). They appear not to be required since you are able to arrive at the relevant node using the hierarchy in the XML. Also, you already mentioned that the check for uniqueness is based only on the contents of the long element.

I used this

.app_downloads_table tr td:first-child {
    width: 75%;
}

.app_downloads_table tr td:last-child {
    text-align: center;
}

As addition to the accepted answer:

To see the hashes you need to use the suggested command "git checkout hash", you can use git log. Hoewever, depending on what you need, there is an easier way than copy/pasting hashes.

You can use git log --oneline to read many commit messages in a more compressed format.

Lets say you see this a one-line list of the commits with minimal information and only partly visible hashes:

hash111 (HEAD -> master, origin/master, origin/HEAD)
hash222 last commit
hash333 I want this one
hash444 did something
....

If you want last commit, you can use git checkout master^. The ^ gives you the commit before the master. So hash222.

If you want the n-th last commit, you can use git checkout master~n. For example, using git checkout master~2would give you the commit hash333.

The best move is to just nest a flexbox inside of a flexbox. All you have to do is give the child align-items: center. This will vertically align the text inside of its parent.

// Assuming a horizontally centered row of items for the parent but it doesn't have to be
.parent {
  align-items: center;
  display: flex;
  justify-content: center;
}

.child {
  display: flex;
  align-items: center;
}

Command:

netstat -aon | findstr 4723

Output:

TCP    0.0.0.0:4723           0.0.0.0:0                LISTENING       10396

Now cut the process ID, "10396", using the for command in Windows.

Command:

for /f "tokens=5" %a in ('netstat -aon ^| findstr 4723') do @echo %~nxa

Output:

10396

If you want to cut the 4th number of the value means "LISTENING" then command in Windows.

Command:

for /f "tokens=4" %a in ('netstat -aon ^| findstr 4723') do @echo %~nxa

Output:

LISTENING

Very simple ! Here is my suggestion :

If you want to select dataframes in your workspace, try this :

Filter(function(x) is.data.frame(get(x)) , ls())

or

ls()[sapply(ls(), function(x) is.data.frame(get(x)))]

all these will give the same result.

You can change is.data.frame to check other types of variables like is.function

Have you tried the uncurl package (https://github.com/spulec/uncurl)? You can install it via pip, pip install uncurl. Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },

I took a look at the datejs and stripped out the code necessary to add months to a date handling edge cases (leap year, shorter months, etc):

Date.isLeapYear = function (year) { 
    return (((year % 4 === 0) && (year % 100 !== 0)) || (year % 400 === 0)); 
};

Date.getDaysInMonth = function (year, month) {
    return [31, (Date.isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
};

Date.prototype.isLeapYear = function () { 
    return Date.isLeapYear(this.getFullYear()); 
};

Date.prototype.getDaysInMonth = function () { 
    return Date.getDaysInMonth(this.getFullYear(), this.getMonth());
};

Date.prototype.addMonths = function (value) {
    var n = this.getDate();
    this.setDate(1);
    this.setMonth(this.getMonth() + value);
    this.setDate(Math.min(n, this.getDaysInMonth()));
    return this;
};

This will add "addMonths()" function to any javascript date object that should handle edge cases. Thanks to Coolite Inc!

Use:

var myDate = new Date("01/31/2012");
var result1 = myDate.addMonths(1);

var myDate2 = new Date("01/31/2011");
var result2 = myDate2.addMonths(1);

->> newDate.addMonths -> mydate.addMonths

result1 = "Feb 29 2012"

result2 = "Feb 28 2011"

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

A small addition to the solutions before: object_id(@TableName) works only if you are in the default schema.

(Select id from sysobjects where name = @TableName)

works in any schema provided @tableName is unique.

Are these servers virtualized? On another post I've read about a SQL server running sometimes very slowly because of lack of sufficient memory. This in turn was caused by a so-called memory balloon that the virtualizer used to limit the amount of memory used by that virtual server. It was hard to find because the pressure on physical memory had nothing to do with the SQL server itself.

Another common cause for a temporary performance degradation might be a virus scanner. When a new virus definition is installed, all other processes will suffer and run very slow. Check out any other automatic update process, this might also take a lot of resources quite unexpectedly. Good luck with it!

In a Ruby on Rails application (especially with something like the Prawn gem and the Prawnto Rails plugin), you can accomplish this a little more simply than a full on script (like the previous PHP example).

In your controller:

def index

 respond_to do |format|
   format.html # Your HTML view
   format.pdf { render :layout => false }
 end
end

The render :layout => false part tells the browser to open up the "Would you like to download this file?" prompt instead of attempting to render the PDF. Then you would be able to link to the file normally: http://mysite.com/myawesomepdf.pdf

Out of the box, the == operator only works for primitives. To get your code to work, you need to overload the == operator for your struct.

CSS

overflow-y: scroll;

See it on jsFiddle.

Notice if you remove the -y from the overflow-y property, the horizontal scroll bar is shown.

almost the same thing as David G's answer but without the anonymous function, if you don't feel like including one.

s = s.substr(0, s.indexOf(',') === -1 ? s.length : s.indexOf(','));

in this case we make use of the fact that the second argument of substr is a length, and that we know our substring is starting at 0.

the top answer is not a generic solution because of the undesirable behavior if the string doesn't contain the character you are looking for.

if you want correct behavior in a generic case, use this method or David G's method, not the top answer

regex and split methods will also work, but may be somewhat slower / overkill for this specific problem.

MS-SQL has a setting to prevent recursive trigger firing. This is confirgured via the sp_configure stored proceedure, where you can turn recursive or nested triggers on or off.

In this case, it would be possible, if you turn off recursive triggers to link the record from the inserted table via the primary key, and make changes to the record.

In the specific case in the question, it is not really a problem, because the result is to delete the record, which won't refire this particular trigger, but in general that could be a valid approach. We implemented optimistic concurrency this way.

The code for your trigger that could be used in this way would be:

ALTER TRIGGER myTrigger
    ON someTable
    AFTER INSERT
AS BEGIN
DELETE FROM someTable
    INNER JOIN inserted on inserted.primarykey = someTable.primarykey
    WHERE ISNUMERIC(inserted.someField) = 1
END

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

StringBuilder sb = new StringBuilder("abcde");
sb.setCharAt(0, 'b');
sb.setCharAt(1, 'a');
String newString = sb.toString();
