You can't create a new branch with this command

git checkout --track origin/branch

if you have changes that are not staged.

Here is example:

$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   src/App.js

no changes added to commit (use "git add" and/or "git commit -a")

// TRY TO CREATE:

$ git checkout --track origin/new-branch
fatal: 'origin/new-branch' is not a commit and a branch 'new-branch' cannot be created from it

However you can easily create a new branch with un-staged changes with git checkout -b command:

$ git checkout -b new-branch
Switched to a new branch 'new-branch'
M       src/App.js

For me I had a typo and my remote branch didn't exist

Use git branch -a to list remote branches

For many cases (such as merging), you can just use the remote branch without having to update the local tracking branch. Adding a message in the reflog sounds like overkill and will stop it being quicker. To make it easier to recover, add the following into your git config

[core]
    logallrefupdates=true

Then type

git reflog show mybranch

to see the recent history for your branch

Maybe not the best solution, (will rewrite history) but you could also do git reset --hard <hash of detached head commit>.

Andy's solution does not work for me. Here I found another way:

git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`

Git: checkout by date

Sidenote: With modern Git (>= 1.6.6), you are able to use just

git checkout test

(note that it is 'test' not 'origin/test') to perform magical DWIM-mery and create local branch 'test' for you, for which upstream would be remote-tracking branch 'origin/test'.

The * (no branch) in git branch output means that you are on unnamed branch, in so called "detached HEAD" state (HEAD points directly to commit, and is not symbolic reference to some local branch). If you made some commits on this unnamed branch, you can always create local branch off current commit:

git checkout -b test HEAD

** EDIT (by editor not author) **

I found a comment buried below which seems to modernize this answer:

@Dennis: git checkout <non-branch>, for example git checkout origin/test results in detached HEAD / unnamed branch, while git checkout test or git checkout -b test origin/test results in local branch test (with remote-tracking branch origin/test as upstream) – Jakub Narebski Jan 9 '14 at 8:17

emphasis on git checkout origin/test

• git checkout modifies your working tree,
• git reset modifies which reference the branch you're on points to,
• git revert adds a commit undoing changes.

I had the same issue and none of the solutions above worked for me. I deleted the offending folder. Then:

git reset --hard

Deleted any lingering files to clean up the git status, then did:

git pull

It finally worked.

NOTE: If the folder was, for instance, a public folder with build files, remember to rebuild the files

One simple use case when reverting change:
1. Use reset if you want to undo staging of a modified file.
2. Use checkout if you want to discard changes to unstaged file/s.

Before answering let's add some background, explaining what this HEAD is.

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch. There can only be a single HEAD at any given time (excluding git worktree).

The content of HEAD is stored inside .git/HEAD, and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history it's called detached HEAD.

On the command line it will look like this - SHA-1 instead of the branch name since the HEAD is not pointing to the the tip of the current branch:

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back

This will checkout new branch pointing to the desired commit. This command will checkout to a given commit.

At this point you can create a branch and start to work from this point on:

# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# Create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well. git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset HEAD --hard <commit_id>

"Move" your head back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts, if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7) you can also use the git rebase --no-autostash as well.

This schema illustrates which command does what. As you can see there reset && checkout modify the HEAD.

I tried the above solutions and I was still having difficulties. I had other files staged with two files that were deleted accidentally.

To undo the two deleted files I had to unstage all of the files:

git reset HEAD .

At that point I was able to do the checkout of the deleted items:

git checkout -- WorkingFolder/FileName.ext

Finally I was able to restage the rest of the files and continue with my commit.

And to revert to last committed version, which is most frequently needed, you can use this simpler command.

git checkout HEAD file/to/restore

git checkout master should do the trick. To go back two versions, you could say something like git checkout HEAD~2, but better to create a temporary branch based on that time, so git checkout -b temp_branch HEAD~2

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

Try this

git checkout master

git pull origin master

One way to end up in this situation is after doing a rebase from a remote branch. In this case, the new commits are pointed to by HEAD but master does not point to them -- it's pointing to wherever it was before you rebased the other branch.

You can make this commit your new master by doing:

git branch -f master HEAD
git checkout master

This forcibly updates master to point to HEAD (without putting you on master) then switches to master.

Check remote branch list:

git branch -a

Switch to another Branch:

git checkout -b <local branch name> <Remote branch name>
Example: git checkout -b Dev_8.4 remotes/gerrit/Dev_8.4

Check local Branch list:

git branch

Update everything:

git pull

For the best way to do that, try it.

First, find the commit id of the commit that deleted your file. It will give you a summary of commits which deleted files.

git log --diff-filter=D --summary

git checkout 84sdhfddbdddf~1

Note: 84sdhfddbddd is your commit id

Through this you can easily recover all deleted files.

I think I have found an easy hack out.

Delete the file that you have on the local repository (the file that you want updated from the latest commit in the remote server)

And then do a git pull

Because the file is deleted, there will be no conflict

Let's start by explaining what a tag in git is

A tag is used to label and mark a specific commit in the history.
It is usually used to mark release points (eg. v1.0, etc.).

Although a tag may appear similar to a branch, a tag, however, does not change. It points directly to a specific commit in the history and will not change unless explicitly updated.

You will not be able to checkout the tags if it's not locally in your repository so first, you have to fetch the tags to your local repository.

First, make sure that the tag exists locally by doing

# --all will fetch all the remotes.
# --tags will fetch all tags as well
$ git fetch --all --tags --prune

Then check out the tag by running

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

Instead of origin use the tags/ prefix.

In this sample you have 2 tags version 1.0 & version 1.1 you can check them out with any of the following:

$ git checkout A  ...
$ git checkout version 1.0  ...
$ git checkout tags/version 1.0  ...

All of the above will do the same since the tag is only a pointer to a given commit.

origin: https://backlog.com/git-tutorial/img/post/stepup/capture_stepup4_1_1.png

How to see the list of all tags?

# list all tags
$ git tag

# list all tags with given pattern ex: v-
$ git tag --list 'v-*'

How to create tags?

There are 2 ways to create a tag:

# lightweight tag 
$ git tag 

# annotated tag
$ git tag -a

The difference between the 2 is that when creating an annotated tag you can add metadata as you have in a git commit:
name, e-mail, date, comment & signature

How to delete tags?

Delete a local tag

$ git tag -d <tag_name>
Deleted tag <tag_name> (was 000000)

Note: If you try to delete a non existig Git tag, there will be see the following error:

$ git tag -d <tag_name>
error: tag '<tag_name>' not found.

Delete remote tags

# Delete a tag from the server with push tags
$ git push --delete origin <tag name>

How to clone a specific tag?

In order to grab the content of a given tag, you can use the checkout command. As explained above tags are like any other commits so we can use checkout and instead of using the SHA-1 simply replacing it with the tag_name

Option 1:

# Update the local git repo with the latest tags from all remotes
$ git fetch --all

# checkout the specific tag
$ git checkout tags/<tag> -b <branch>

Option 2:

Using the clone command

Since git supports shallow clone by adding the --branch to the clone command we can use the tag name instead of the branch name. Git knows how to "translate" the given SHA-1 to the relevant commit

# Clone a specific tag name using git clone 
$ git clone <url> --branch=<tag_name>

git clone --branch=

--branch can also take tags and detaches the HEAD at that commit in the resulting repository.

How to push tags?

git push --tags

To push all tags:

# Push all tags
$ git push --tags 

Using the refs/tags instead of just specifying the <tagname>.

Why?

• It's recommended to use refs/tags since sometimes tags can have the same name as your branches and a simple git push will push the branch instead of the tag

To push annotated tags and current history chain tags use:

git push --follow-tags

This flag --follow-tags pushes both commits and only tags that are both:

• Annotated tags (so you can skip local/temp build tags)
• Reachable tags (an ancestor) from the current branch (located on the history)

From Git 2.4 you can set it using configuration

$ git config --global push.followTags true

Cheatsheet:

Originally, I mentioned in 2012 git archive (see Jared Forsyth's answer and Robert Knight's answer), since git1.7.9.5 (March 2012), Paul Brannan's answer:

git archive --format=tar --remote=origin HEAD:path/to/directory -- filename | tar -O -xf -

But: in 2013, that was no longer possible for remote https://github.com URLs.
See the old page "Can I archive a repository?"

The current (2018) page "About archiving content and data on GitHub" recommends using third-party services like GHTorrent or GH Archive.

So you can also deal with local copies/clone:

You could alternatively do the following if you have a local copy of the bare repository as mentioned in this answer,

git --no-pager --git-dir /path/to/bar/repo.git show branch:path/to/file >file

Or you must clone first the repo, meaning you get the full history: - in the .git repo - in the working tree.

• But then you can do a sparse checkout (if you are using Git1.7+),:
  • enable the sparse checkout option (git config core.sparsecheckout true)
  • adding what you want to see in the .git/info/sparse-checkout file
  • re-reading the working tree to only display what you need

To re-read the working tree:

$ git read-tree -m -u HEAD

That way, you end up with a working tree including precisely what you want (even if it is only one file)

Richard Gomes points (in the comments) to "How do I clone, fetch or sparse checkout a single directory or a list of directories from git repository?"

A bash function which avoids downloading the history, which retrieves a single branch and which retrieves a list of files or directories you need.

Follow,

$: git checkout -f

$: git checkout next_branch

Try this:

git checkout [revision] .

where [revision] is the commit hash (for example: 12345678901234567890123456789012345678ab).

Don't forget the . at the end, very important. This will apply changes to the whole tree. You should execute this command in the git project root. If you are in any sub directory, then this command only changes the files in the current directory. Then commit and you should be good.

You can undo this by

git reset --hard 

that will delete all modifications from the working directory and staging area.

When I run git branch, it only shows *master, not the remaining two branches.

git branch doesn't list test_branch, because no such local branch exist in your local repo, yet. When cloning a repo, only one local branch (master, here) is created and checked out in the resulting clone, irrespective of the number of branches that exist in the remote repo that you cloned from. At this stage, test_branch only exist in your repo as a remote-tracking branch, not as a local branch.

And when I run

git checkout test-branch

I get the following error [...]

You must be using an "old" version of Git. In more recent versions (from v1.7.0-rc0 onwards),

If <branch> is not found but there does exist a tracking branch in exactly one remote (call it <remote>) with a matching name, treat [git checkout <branch>] as equivalent to

$ git checkout -b <branch> --track <remote>/<branch>

Simply run

git checkout -b test_branch --track origin/test_branch

instead. Or update to a more recent version of Git.

This error happens when the branch you are switching to, has changes that your current branch doesn't have.

If you are seeing this error when you try to switch to a new branch, then your current branch is probably behind one or more commits. If so, run:

git fetch

You should also remove dependencies which may also conflict with the destination branch.

For example, for iOS developers:

pod deintegrate

then try checking out a branch again.

If the desired branch isn't new you can either cherry pick a commit and fix the conflicts or stash the changes and then fix the conflicts.

1. Git Stash (recommended)

git stash
git checkout <desiredBranch>
git stash apply

2. Cherry pick (more work)

git add <your file>
git commit -m "Your message"
git log

Copy the sha of your commit. Then discard unwanted changes:

git checkout .
git checkout -- . 
git clean -f -fd -fx

Make sure your branch is up to date:

git fetch

Then checkout to the desired branch

git checkout <desiredBranch>

Then cherry pick the other commit:

git cherry-pick <theSha>

Now fix the conflict.

3. Otherwise, your other option is to abandon your current branches changes with:

git checkout -f branch

Supplemental to VonC's and chhh's answers.

git show experiment:path/to/relative/app.js > app.js
# If your current working directory is relative than just use
git show experiment:app.js > app.js

or

git checkout experiment -- app.js

With Git 2.23 (August 2019), that would be, using git switch -f:

git switch -f master

That avoids the confusion with git checkout (which deals with files or branches).

And that will proceeds, even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
If --recurse-submodules is specified, submodule content is also restored to match the switching target.
This is used to throw away local changes.

If you want to checkout all the files 'anywhere'

git checkout -- $(git rev-parse --show-toplevel)

Note: You may also want to run

git clean -fd

as

git reset --hard

will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under git tracking. WARNING - BE CAREFUL WITH THIS! It is helpful to run a dry-run with git-clean first, to see what it will delete.

This is also especially useful when you get the error message

~"performing this command will cause an un-tracked file to be overwritten"

Which can occur when doing several things, one being updating a working copy when you and your friend have both added a new file of the same name, but he's committed it into source control first, and you don't care about deleting your untracked copy.

In this situation, doing a dry run will also help show you a list of files that would be overwritten.

Note that Git 2.5 (Q2 2015) a future Git might try to make that scenario impossible.

See commit ed178ef by Jeff King (peff), 22 Apr 2015.
^{(Merged by Junio C Hamano -- gitster -- in commit 05c3967, 19 May 2015)}

Note: This has been reverted. See below.

stash: require a clean index to apply/pop

Problem

If you have staged contents in your index and run "stash apply/pop", we may hit a conflict and put new entries into the index.
Recovering to your original state is difficult at that point, because tools like "git reset --keep" will blow away anything staged.

In other words:

"git stash pop/apply" forgot to make sure that not just the working tree is clean but also the index is clean.
The latter is important as a stash application can conflict and the index will be used for conflict resolution.

Solution

We can make this safer by refusing to apply when there are staged changes.

That means if there were merges before because of applying a stash on modified files (added but not committed), now they would not be any merges because the stash apply/pop would stop immediately with:

Cannot apply stash: Your index contains uncommitted changes.

Forcing you to commit the changes means that, in case of merges, you can easily restore the initial state( before git stash apply/pop) with a git reset --hard.

See commit 1937610 (15 Jun 2015), and commit ed178ef (22 Apr 2015) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit bfb539b, 24 Jun 2015)}

That commit was an attempt to improve the safety of applying a stash, because the application process may create conflicted index entries, after which it is hard to restore the original index state.

Unfortunately, this hurts some common workflows around "git stash -k", like:

git add -p       ;# (1) stage set of proposed changes
git stash -k     ;# (2) get rid of everything else
make test        ;# (3) make sure proposal is reasonable
git stash apply  ;# (4) restore original working tree

If you "git commit" between steps (3) and (4), then this just works. However, if these steps are part of a pre-commit hook, you don't have that opportunity (you have to restore the original state regardless of whether the tests passed or failed).

I find git stash very useful for temporal handling of all 'dirty' states.

"Most recent" could have two meanings in terms of git.

You could mean, "which tag has the creation date latest in time", and most of the answers here are for that question. In terms of your question, you would want to return tag c.

Or you could mean "which tag is the closest in development history to some named branch", usually the branch you are on, HEAD. In your question, this would return tag a.

These might be different of course:

A->B->C->D->E->F (HEAD)
       \     \
        \     X->Y->Z (v0.2)
         P->Q (v0.1)

Imagine the developer tag'ed Z as v0.2 on Monday, and then tag'ed Q as v0.1 on Tuesday. v0.1 is the more recent, but v0.2 is closer in development history to HEAD, in the sense that the path it is on starts at a point closer to HEAD.

I think you usually want this second answer, closer in development history. You can find that out by using git log v0.2..HEAD etc for each tag. This gives you the number of commits on HEAD since the path ending at v0.2 diverged from the path followed by HEAD.

Here's a Python script that does that by iterating through all the tags running this check, and then printing out the tag with fewest commits on HEAD since the tag path diverged:

https://github.com/MacPython/terryfy/blob/master/git-closest-tag

git describe does something slightly different, in that it tracks back from (e.g.) HEAD to find the first tag that is on a path back in the history from HEAD. In git terms, git describe looks for tags that are "reachable" from HEAD. It will therefore not find tags like v0.2 that are not on the path back from HEAD, but a path that diverged from there.

Suppose your origin and upstream info is like below

   $ git remote -v
   origin  [email protected]:<yourname>/<repo_name>.git (fetch)
   origin  [email protected]:<yourname>/<repo_name>.git (push)
   upstream   [email protected]:<repo_owner>/<repo_name>.git (fetch)
   upstream   [email protected]:<repo_owner>/<repo_name>.git (push)

and your branch name is like

   <repo_owner>:<BranchName>

then

   git pull origin <BranchName>

shall do the job

If you have a typo in your branchname you'll get this same error.

Today, I mistakenly checked out on a commit and started working on it, making some commits on a detach HEAD state. Then I pushed to the remote branch using the following command:

git push origin HEAD: <My-remote-branch>

Then

git checkout <My-remote-branch>

Then

git pull

I finally got my all changes in my branch that I made in detach HEAD.

Edit: Jakub Narebski has more git-fu. The following much simpler command works perfectly:

git describe --tags

(Or without the --tags if you have checked out an annotated tag. My tag is lightweight, so I need the --tags.)

original answer follows:

git describe --exact-match --tags $(git log -n1 --pretty='%h')

Someone with more git-fu may have a more elegant solution...

This leverages the fact that git-log reports the log starting from what you've checked out. %h prints the abbreviated hash. Then git describe --exact-match --tags finds the tag (lightweight or annotated) that exactly matches that commit.

The $() syntax above assumes you're using bash or similar.

Assuming that your branch is called master both here and remotely, and that your remote is called origin you could do:

git reset --hard <commit-hash>
git push -f origin master

However, you should avoid doing this if anyone else is working with your remote repository and has pulled your changes. In that case, it would be better to revert the commits that you don't want, then push as normal.

The following 2 commands worked for me:

git archive --remote={remote_repo_git_url} {branch} {file_to_download} -o {tar_out_file}

Downloads file_to_download as tar archive from branch of remote repository whose url is remote_repo_git_url and stores it in tar_out_file

tar -x -f {tar_out_file}.tar extracts the file_to_download from tar_out_file

git reset and git clean can be overkill in some situations (and be a huge waste of time).

If you simply have a message like "The following untracked files would be overwritten..." and you want the remote/origin/upstream to overwrite those conflicting untracked files, then git checkout -f <branch> is the best option.

If you're like me, your other option was to clean and perform a --hard reset then recompile your project.

INNER JOIN gets all records that are common between both tables based on the supplied ON clause.

LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.

RIGHT JOIN is like the above but gets all records in the RIGHT table.

FULL JOIN gets all records from both tables and puts NULL in the columns where related records do not exist in the opposite table.

And for those who are looking for when you have to concatenate a char to a String rather than a String to another String as given below.

char ch = 'a';
String otherstring = "helen";
// do this
otherstring = otherstring + "" + ch;
System.out.println(otherstring);
// output : helena

You could also try this.

public static int[] addOneIntToArray(int[] initialArray , int newValue) {

    int[] newArray = new int[initialArray.length + 1];
    for (int index = 0; index < initialArray.length; index++) {
        newArray[index] = initialArray[index];
    }

    newArray[newArray.length - 1] = newValue;
    return newArray;
}

To answer the original question:

To change the XAMPP Apache server port here the procedure :

1. Choose a free port number

The default port used by Apache is 80.

Take a look to all your used ports with Netstat (integrated to XAMPP Control Panel).

Then you can see all used ports and here we see that the 80port is already used by System.

Choose a free port number (8012, for this exemple).

2. Edit the file "httpd.conf"

This file should be found in C:\xampp\apache\conf on Windows or in bin/apache for Linux.:

Listen 80
ServerName localhost:80

Replace them by:

Listen 8012
ServerName localhost:8012

Save the file.

Access to : http://localhost:8012 for check if it's work.

If not, you must to edit the http-ssl.conf file as explain in step 3 below. ?

3. Edit the file "http-ssl.conf"

This file should be found in C:\xampp\apache\conf\extra on Windows or see this link for Linux.

Locate the following lines:

Listen 443
<VirtualHost _default_:443>
ServerName localhost:443

Replace them by with a other port number (8013 for this example) :

Listen 8013
<VirtualHost _default_:8013>
ServerName localhost:8013

Save the file.

Restart the Apache Server.

Access to : http://localhost:8012 for check if it's work.

4. Configure XAMPP Apache server settings

If your want to access localhost without specify the port number in the URL
http://localhost instead of http://localhost:8012.

• Open Xampp Control Panel
• Go to Config ? Service and Port Settings ? Apache
• Replace the Main Port and SSL Port values ??with those chosen (e.g. 8012 and 8013).
• Save Service settings
• Save Configuration of Control Panel
• Restart the Apache Server It should work now.

4.1. Web browser configuration

If this configuration isn't hiding port number in URL it's because your web browser is not configured for. See : Tools ? Options ? General ? Connection Settings... will allow you to choose different ports or change proxy settings.

4.2. For the rare cases of ultimate bad luck

If step 4 and Web browser configuration are not working for you the only way to do this is to change back to 80, or to install a listener on port 80 (like a proxy) that redirects all your traffic to port 8012.

To answer your problem :

If you still have this message in Control Panel Console :

Apache Started [Port 80]

• Find location of xampp-control.exe file (probably in C:\xampp)
• Create a file XAMPP.INI in that directory (so XAMPP.ini and xampp-control.exe are in the same directory)

Put following lines in the XAMPP.INI file:

[PORTS]
apache = 8012

Now , you will always get:

Apache started [Port 8012]

Please note that, this is for display purpose only. It has no relation with your httpd.conf.

When they say "The bottom of the page" they don't literally mean the bottom: they mean just before the closing </body> tag. Place your scripts there and they will be loaded before the DOMReady event; place them afterwards and the DOM will be ready before they are loaded (because it's complete when the closing </html> tag is parsed), which as you have found will not work.

If you're wondering how I know that this is what they mean: I have worked at Yahoo! and we put our scripts just before the </body> tag :-)

EDIT: also, see T.J. Crowder's reply and make sure you have things in the correct order.

Despite not fully answering the original question, this is probably what most people googling this wanted to see.

For GCC:

$ cat test.cpp 
#include <iostream>

int main(int argc, char **argv)
{
    std::cout << __func__ << std::endl
              << __FUNCTION__ << std::endl
              << __PRETTY_FUNCTION__ << std::endl;
}
$ g++ test.cpp 
$ ./a.out 
main

int main(int, char**)

If you are debugging an ASP.NET website using Internet Explorer 10 (and later), make sure to turn off your Internet Explorer 'LastPass' password manager plugin. LastPass will bring your debugging sessions to a crawl and significantly reduce your capacity for patience!

I submitted a support ticket to Lastpass about this and they acknowledged the issue without any intention to fix it, merely saying: "LastPass is not compatible with Visual Studio 2013".

Add android.permission.READ_EXTERNAL_STORAGE in manifest, worked for me

Consider this example:

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|")));
    // output : [Real, How, To]
  }
}

The result does not include the empty strings between the "|" separator. To keep the empty strings :

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|", -1)));
    // output : [Real, How, To, , , ]
  }
}

Date.now() returns a unix timestamp in milliseconds.

const now = Date.now(); // Unix timestamp in milliseconds_x000D_
console.log( now );

Prior to ECMAScript5 (I.E. Internet Explorer 8 and older) you needed to construct a Date object, from which there are several ways to get a unix timestamp in milliseconds:

console.log( +new Date );_x000D_
console.log( (new Date).getTime() );_x000D_
console.log( (new Date).valueOf() );

Its all about Method Overloading.

There are individual methods for each data type in println() method

If you pass object :

Prints an Object and then terminate the line. This method calls at first String.valueOf(x) to get the printed object's string value, then behaves as though it invokes print(String) and then println().

If you pass Primitive type:

corresponding primitive type method calls

if you pass String :

corresponding println(String x) method calls

An unsigned char is an unsigned byte value (0 to 255). You may be thinking of char in terms of being a "character" but it is really a numerical value. The regular char is signed, so you have 128 values, and these values map to characters using ASCII encoding. But in either case, what you are storing in memory is a byte value.

Install same version javac as your JRE

• Value Object : Use when need to measure the objects' equality based on the objects' value.
• Data Transfer Object : Pass data with multiple attributes in one shot from client to server across layer, to avoid multiple calls to remote server.
• Plain Old Java Object : It's like simple class which properties, public no-arg constructor. As we declare for JPA entity.

This is known as packing points on a sphere, and there is no (known) general, perfect solution. However, there are plenty of imperfect solutions. The three most popular seem to be:

1. Create a simulation. Treat each point as an electron constrained to a sphere, then run a simulation for a certain number of steps. The electrons' repulsion will naturally tend the system to a more stable state, where the points are about as far away from each other as they can get.
2. Hypercube rejection. This fancy-sounding method is actually really simple: you uniformly choose points (much more than n of them) inside of the cube surrounding the sphere, then reject the points outside of the sphere. Treat the remaining points as vectors, and normalize them. These are your "samples" - choose n of them using some method (randomly, greedy, etc).
3. Spiral approximations. You trace a spiral around a sphere, and evenly-distribute the points around the spiral. Because of the mathematics involved, these are more complicated to understand than the simulation, but much faster (and probably involving less code). The most popular seems to be by Saff, et al.

It seems there is a change in how Application.COUNTA works in VB7 vs VB6. I tried the following in both versions of VB.

   ReDim allData(0 To 1, 0 To 15)
   Debug.Print Application.WorksheetFunction.CountA(allData)

In VB6 this returns 0.

Inn VB7 it returns 32

Looks like VB7 doesn't consider COUNTA to be COUNTA anymore.

Here is an elegant way to do similar thing. But why do partly JSON unmarshal? That doesn't make sense.

1. Create your structs for the Chat.
2. Decode json to the Struct.
3. Now you can access everything in Struct/Object easily.

Look below at the working code. Copy and paste it.

import (
   "bytes"
   "encoding/json" // Encoding and Decoding Package
   "fmt"
 )

var messeging = `{
"say":"Hello",
"sendMsg":{
    "user":"ANisus",
    "msg":"Trying to send a message"
   }
}`

type SendMsg struct {
   User string `json:"user"`
   Msg  string `json:"msg"`
}

 type Chat struct {
   Say     string   `json:"say"`
   SendMsg *SendMsg `json:"sendMsg"`
}

func main() {
  /** Clean way to solve Json Decoding in Go */
  /** Excellent solution */

   var chat Chat
   r := bytes.NewReader([]byte(messeging))
   chatErr := json.NewDecoder(r).Decode(&chat)
   errHandler(chatErr)
   fmt.Println(chat.Say)
   fmt.Println(chat.SendMsg.User)
   fmt.Println(chat.SendMsg.Msg)

}

 func errHandler(err error) {
   if err != nil {
     fmt.Println(err)
     return
   }
 }

It is the ternary conditional operator.

If the condition in the parenthesis before the ? is true, it returns the value to the left of the :, otherwise the value to the right.

#!/usr/bin/env bash
while [ "$1" != "" ]; do
  echo "Received: ${1}" && shift;
done;

Just thought this may be a bit more useful when trying to test how args come into your script

? public makes it accessible across the other classes. You can use it without instantiate of the class or using any object.

? static makes it uniform value across all the class instances. It ensures that you don't waste memory creating many of the same thing if it will be the same value for all the objects.

? final makes it non-modifiable value. It's a "constant" value which is same across all the class instances and cannot be modified.

Consider this code,

int some_int = 100;

while(some_int == 100)
{
   //your code
}

When this program gets compiled, the compiler may optimize this code, if it finds that the program never ever makes any attempt to change the value of some_int, so it may be tempted to optimize the while loop by changing it from while(some_int == 100) to something which is equivalent to while(true) so that the execution could be fast (since the condition in while loop appears to be true always). (if the compiler doesn't optimize it, then it has to fetch the value of some_int and compare it with 100, in each iteration which obviously is a little bit slow.)

However, sometimes, optimization (of some parts of your program) may be undesirable, because it may be that someone else is changing the value of some_int from outside the program which compiler is not aware of, since it can't see it; but it's how you've designed it. In that case, compiler's optimization would not produce the desired result!

So, to ensure the desired result, you need to somehow stop the compiler from optimizing the while loop. That is where the volatile keyword plays its role. All you need to do is this,

volatile int some_int = 100; //note the 'volatile' qualifier now!

In other words, I would explain this as follows:

volatile tells the compiler that,

"Hey compiler, I'm volatile and, you know, I can be changed by some XYZ that you're not even aware of. That XYZ could be anything. Maybe some alien outside this planet called program. Maybe some lightning, some form of interrupt, volcanoes, etc can mutate me. Maybe. You never know who is going to change me! So O you ignorant, stop playing an all-knowing god, and don't dare touch the code where I'm present. Okay?"

Well, that is how volatile prevents the compiler from optimizing code. Now search the web to see some sample examples.

Quoting from the C++ Standard ($7.1.5.1/8)

[..] volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation.[...]

Does making a struct volatile make all its members volatile?

Now Chrome is multi-user so Extensions should be nested under the OS user profile then the Chrome user profile, My first Chrome user was called Profile 1, my Extensions path was C:\Users\ username \AppData\Local\Google\Chrome\User Data\ Profile 1 \Extensions\.

To find yours Navigate to chrome://version/ (I use about: out of laziness).

Notice the Profile Path and just append \Extensions\ and you have yours.

Hope this brings this info on this question up to date more.

let copy = Object.assign({}, myObject).  as mentioned above

but this wont work for nested objects. SO an alternative would be

let copy =JSON.parse(JSON.stringify(myObject))

Calling axvline in a loop, as others have suggested, works, but can be inconvenient because

1. Each line is a separate plot object, which causes things to be very slow when you have many lines.
2. When you create the legend each line has a new entry, which may not be what you want.

Instead you can use the following convenience functions which create all the lines as a single plot object:

import matplotlib.pyplot as plt
import numpy as np


def axhlines(ys, ax=None, lims=None, **plot_kwargs):
    """
    Draw horizontal lines across plot
    :param ys: A scalar, list, or 1D array of vertical offsets
    :param ax: The axis (or none to use gca)
    :param lims: Optionally the (xmin, xmax) of the lines
    :param plot_kwargs: Keyword arguments to be passed to plot
    :return: The plot object corresponding to the lines.
    """
    if ax is None:
        ax = plt.gca()
    ys = np.array((ys, ) if np.isscalar(ys) else ys, copy=False)
    if lims is None:
        lims = ax.get_xlim()
    y_points = np.repeat(ys[:, None], repeats=3, axis=1).flatten()
    x_points = np.repeat(np.array(lims + (np.nan, ))[None, :], repeats=len(ys), axis=0).flatten()
    plot = ax.plot(x_points, y_points, scalex = False, **plot_kwargs)
    return plot


def axvlines(xs, ax=None, lims=None, **plot_kwargs):
    """
    Draw vertical lines on plot
    :param xs: A scalar, list, or 1D array of horizontal offsets
    :param ax: The axis (or none to use gca)
    :param lims: Optionally the (ymin, ymax) of the lines
    :param plot_kwargs: Keyword arguments to be passed to plot
    :return: The plot object corresponding to the lines.
    """
    if ax is None:
        ax = plt.gca()
    xs = np.array((xs, ) if np.isscalar(xs) else xs, copy=False)
    if lims is None:
        lims = ax.get_ylim()
    x_points = np.repeat(xs[:, None], repeats=3, axis=1).flatten()
    y_points = np.repeat(np.array(lims + (np.nan, ))[None, :], repeats=len(xs), axis=0).flatten()
    plot = ax.plot(x_points, y_points, scaley = False, **plot_kwargs)
    return plot

Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent() . Example:

list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());

• Add a Resource file to your project (you can call it "strings.resx") by doing the following:
  Right-click Properties in the project, select Add -> New Item... in the context menu, then in the list of Visual C# Items pick "Resources file" and name it strings.resx.
• Add a string resouce in the resx file and give it a good name (example: name it "Hello" with and give it the value "Hello")
• Save the resource file (note: this will be the default resource file, since it does not have a two-letter language code)
• Add references to your program: System.Threading and System.Globalization

Run this code:

Console.WriteLine(Properties.strings.Hello);

It should print "Hello".

Now, add a new resource file, named "strings.fr.resx" (note the "fr" part; this one will contain resources in French). Add a string resource with the same name as in strings.resx, but with the value in French (Name="Hello", Value="Salut"). Now, if you run the following code, it should print Salut:

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("fr-FR");
Console.WriteLine(Properties.strings.Hello);

What happens is that the system will look for a resource for "fr-FR". It will not find one (since we specified "fr" in your file"). It will then fall back to checking for "fr", which it finds (and uses).

The following code, will print "Hello":

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("en-US");
Console.WriteLine(Properties.strings.Hello);

That is because it does not find any "en-US" resource, and also no "en" resource, so it will fall back to the default, which is the one that we added from the start.

You can create files with more specific resources if needed (for instance strings.fr-FR.resx and strings.fr-CA.resx for French in France and Canada respectively). In each such file you will need to add the resources for those strings that differ from the resource that it would fall back to. So if a text is the same in France and Canada, you can put it in strings.fr.resx, while strings that are different in Canadian french could go into strings.fr-CA.resx.

Mike; Everytime I need to modify an XML document I work it this way:

//Here is the variable with which you assign a new value to the attribute
string newValue = string.Empty;
XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(xmlFile);

XmlNode node = xmlDoc.SelectSingleNode("Root/Node/Element");
node.Attributes[0].Value = newValue;

xmlDoc.Save(xmlFile);

//xmlFile is the path of your file to be modified

I hope you find it useful

By default, Java opens it in the working directory of your application (this behavior actually depends on the OS used). To load a file, do:

Properties props = new java.util.Properties();
FileInputStream fis new FileInputStream("myfile.txt");
props.load(fis)

As such, any file extension can be used for property file. Additionally, the file can also be stored anywhere, as long as you can use a FileInputStream.

On a related note if you use a modern framework, the framework may provide additionnal ways of opening a property file. For example, Spring provide a ClassPathResource to load a property file using a package name from inside a JAR file.

As for iterating through the properties, once the properties are loaded they are stored in the java.util.Properties object, which offer the propertyNames() method.

I have netbeans 6.9.1 open right now and ALT+SHIFT+F indents only the lines you have selected.

If no lines are selected then it will indent the whole document you are in.

1 possibly unintended behavior is that if you have selected ONLY 1 line, it must be selected completely, otherwise it does nothing. But you don't have to completely select the last line of a group nor the first.

I expected it to indent only one line by just selecting the first couple of chars but didn't work, yea i know i am lazy as hell...

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

My trick. Not elegant, but it works:

<p>&nbsp;</p>

I had the same issue. Fixed by adding a pom.xml in parent folder with <modules> listed.

just past this on head of your php page. before any code on this should be the top code.

<?php
header("Content-Type: application/vnd.ms-word"); 
header("Expires: 0"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("content-disposition: attachment;filename=Hawala.doc");

?>

this will convert all html to MSWORD, now you can customize it according to your client requirement.

Update March 2017: as commented by Anthony Accioly, the scala.Enumeration/enum PR has been closed.

Dotty (next generation compiler for Scala) will take the lead, though dotty issue 1970 and Martin Odersky's PR 1958.

Note: there is now (August 2016, 6+ years later) a proposal to remove scala.Enumeration: PR 5352

Deprecate scala.Enumeration, add @enum annotation

The syntax

@enum
 class Toggle {
  ON
  OFF
 }

is a possible implementation example, intention is to also support ADTs that conform to certain restrictions (no nesting, recursion or varying constructor parameters), e. g.:

@enum
sealed trait Toggle
case object ON  extends Toggle
case object OFF extends Toggle

Deprecates the unmitigated disaster that is scala.Enumeration.

Advantages of @enum over scala.Enumeration:

• Actually works
• Java interop
• No erasure issues
• No confusing mini-DSL to learn when defining enumerations

Disadvantages: None.

This addresses the issue of not being able to have one codebase that supports Scala-JVM, Scala.js and Scala-Native (Java source code not supported on Scala.js/Scala-Native, Scala source code not able to define enums that are accepted by existing APIs on Scala-JVM).

You will never get your app approved by Apple if it is not developed using Xcode. Never. And if you do hack the SDK to develop on Linux and Apple finds out, don't be surprised when you are served. I am a member of the ADC and the iPhone developer program. Trust, Apple is VERY serious about this.

Don't take the risk, Buy a Macbook or Mac mini (yes a mini can run Xcode - though slowly - boost the RAM if you go with the mini). Also, while I've seen OS X hacked to run on VMware I've never seen anyone running Xcode on VM. So good luck. And I'd check the EULA before you go through the trouble.

PS: After reading the above, yes I agree If you do hack the SDK and develop on Linux at least do the final packaging on a Mac. And submit it via a Mac. Apple doesn't run through the code line by line so i doubt they'd catch that. But man, that's a lot of if's and work. Be fun to do though. :)

If you want to use something that is more descriptive than a dumb array without resorting to using a DataSet then the following might prove useful. It still isn't strongly-typed, but at least it is checked by the compiler and will handle being refactored quite well.

Dim previousAllowUserToAddRows = dgvHistoricalInfo.AllowUserToAddRows
dgvHistoricalInfo.AllowUserToAddRows = True

Dim newTimeRecord As DataGridViewRow = dgvHistoricalInfo.Rows(dgvHistoricalInfo.NewRowIndex).Clone

With record
    newTimeRecord.Cells(dgvcDate.Index).Value = .Date
    newTimeRecord.Cells(dgvcHours.Index).Value = .Hours
    newTimeRecord.Cells(dgvcRemarks.Index).Value = .Remarks
End With

dgvHistoricalInfo.Rows.Add(newTimeRecord)

dgvHistoricalInfo.AllowUserToAddRows = previousAllowUserToAddRows

It is worth noting that the user must have AllowUserToAddRows permission or this won't work. That is why I store the existing value, set it to true, do my work, and then reset it to how it was.

We can add the following to a particular tag in CSS:

-webkit-transform: rotate(90deg);
-moz-transform: rotate(90deg);
-o-transform: rotate(90deg);
-ms-transform: rotate(90deg);
transform: rotate(90deg);

In case of half rotation change 90 to 45.

Here is explicitly how to add a line to a batch file that will kill a remote service (on another machine) if you are an admin on both machines, run the .bat as an administrator, and the machines are on the same domain. The machine name follows the UNC format \myserver

In this case... p4_1 was both the Service Name and the Display Name, when you view the Properties for the service in Service Manager. You must use the Service Name.

For your Service Ops junkies... be sure to append your reason code and comment! i.e. '4' which equals 'Planned' and comment 'Stopping server for maintenance'

and call function.

I think, that will be good solution: /\S\w*/

According to MSDN, timestamp

Is a data type that exposes automatically generated, unique binary numbers within a database. timestamp is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The timestamp data type is just an incrementing number and does not preserve a date or a time. To record a date or time, use a datetime data type.

You're probably looking for the datetime data type instead.

        }
    } else {
        for (var i in arr) {
            if (arr[i].name == 'check') arr[i].checked = false;
        }
    }
});

You can also solve this problem by creating an array of values and assigning that array:

newheaders <- c("a", "b", "c", ... "x")
colnames(data) <- newheaders

Throw needs an object instantiated by \Exception. Just the $e catched can play the trick.

throw $e

Bash allows you to place strings adjacently, and they'll just end up being glued together.

So this:

$ echo "Hello"', world!'

produces

Hello, world!

The trick is to alternate between single and double-quoted strings as required. Unfortunately, it quickly gets very messy. For example:

$ echo "I like to use" '"double quotes"' "sometimes"

produces

I like to use "double quotes" sometimes

In your example, I would do it something like this:

$ dbtable=example
$ dbload='load data local infile "'"'gfpoint.csv'"'" into '"table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '"'"'"' LINES "'TERMINATED BY "'"'\n'"'" IGNORE 1 LINES'
$ echo $dbload

which produces the following output:

load data local infile "'gfpoint.csv'" into table example FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY "'\n'" IGNORE 1 LINES

It's difficult to see what's going on here, but I can annotate it using Unicode quotes. The following won't work in bash – it's just for illustration:

dbload=‘load data local infile "’“'gfpoint.csv'”‘" into’“table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '”‘"’“' LINES”‘TERMINATED BY "’“'\n'”‘" IGNORE 1 LINES’

The quotes like “ ‘ ’ ” in the above will be interpreted by bash. The quotes like " ' will end up in the resulting variable.

If I give the same treatment to the earlier example, it looks like this:

$ echo“I like to use”‘"double quotes"’“sometimes”

image_tag is the best way to do the job friend

According to the docs, #Rails.env wraps RAILS_ENV:

    # File vendor/rails/railties/lib/initializer.rb, line 55
     def env
       @_env ||= ActiveSupport::StringInquirer.new(RAILS_ENV)
     end

But, look at specifically how it's wrapped, using ActiveSupport::StringInquirer:

Wrapping a string in this class gives you a prettier way to test for equality. The value returned by Rails.env is wrapped in a StringInquirer object so instead of calling this:

Rails.env == "production"

you can call this:

Rails.env.production?

So they aren't exactly equivalent, but they're fairly close. I haven't used Rails much yet, but I'd say #Rails.env is certainly the more visually attractive option due to using StringInquirer.

I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.

1. Create Excel file/files whose ribbons you want to customise. In my case, I've created two .xlam files, Chart Tools.xlam and Priveleged UDFs.xlam, to demonstrate how multiple add-ins can interact with the Ribbon.
2. Create a folder, with any folder name, for each file you just created.
3. Inside each of the folders you've created, add a customUI and _rels folder.
4. Inside each customUI folder, create a customUI.xml file. The customUI.xml file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml file.

My customUI.xml file for Chart Tools.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:chartToolsTab" label="Chart Tools">
        <group id="relativeChartMovementGroup" label="Relative Chart Movement" >
            <button id="moveChartWithRelativeLinksButton" label="Copy and Move" imageMso="ResultsPaneStartFindAndReplace" onAction="MoveChartWithRelativeLinksCallBack" visible="true" size="normal"/>
            <button id="moveChartToManySheetsWithRelativeLinksButton" label="Copy and Distribute" imageMso="OutlineDemoteToBodyText" onAction="MoveChartToManySheetsWithRelativeLinksCallBack" visible="true" size="normal"/>
        </group >
        <group id="chartDeletionGroup" label="Chart Deletion">
            <button id="deleteAllChartsInWorkbookSharingAnAddressButton" label="Delete Charts" imageMso="CancelRequest" onAction="DeleteAllChartsInWorkbookSharingAnAddressCallBack" visible="true" size="normal"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

My customUI.xml file for Priveleged UDFs.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:privelgedUDFsTab" label="Privelged UDFs">
        <group id="privelgedUDFsGroup" label="Toggle" >
            <button id="initialisePrivelegedUDFsButton" label="Activate" imageMso="TagMarkComplete" onAction="InitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
            <button id="deInitialisePrivelegedUDFsButton" label="De-Activate" imageMso="CancelRequest" onAction="DeInitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
        </group >
      </tab>
    </tabs>
  </ribbon>
</customUI>

5. For each file you created in Step 1, suffix a .zip to their file name. In my case, I renamed Chart Tools.xlam to Chart Tools.xlam.zip, and Privelged UDFs.xlam to Priveleged UDFs.xlam.zip.
6. Open each .zip file, and navigate to the _rels folder. Copy the .rels file to the _rels folder you created in Step 3. Edit each .rels file with a text editor. From the Microsoft guide

Between the final <Relationship> element and the closing <Relationships> element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.

<Relationship Type="http://schemas.microsoft.com/office/2006/
  relationships/ui/extensibility" Target="/customUI/customUI.xml" 
  Id="customUIRelID" />

My .rels file for Chart Tools.xlam looks like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="chartToolsCustomUIRel" />
    </Relationships>

My .rels file for Priveleged UDFs looks like this.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="privelegedUDFsCustomUIRel" />
    </Relationships>

7. Replace the .rels files in each .zip file with the .rels file/files you modified in the previous step.
8. Copy and paste the .customUI folder you created into the home directory of the .zip file/files.
9. Remove the .zip file extension from the Excel files you created.
10. If you've created .xlam files, back in Excel, add them to your Excel add-ins.
11. If applicable, create callbacks in each of your add-ins. In Step 4, there are onAction keywords in my buttons. The onAction keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction keyword. This is known as a callback. In my .xlam files, I have a module called CallBacks where I've included my callback sub-routines.

My CallBacks module for Chart Tools.xlam looks like

Option Explicit

Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartWithRelativeLinks
End Sub

Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartToManySheetsWithRelativeLinks
End Sub

Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
  DeleteAllChartsInWorkbookSharingAnAddress
End Sub

My CallBacks module for Priveleged UDFs.xlam looks like

Option Explicit

Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.InitialisePrivelegedUDFs
End Sub

Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub

Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.

Here's what my finished example looks like

Some closing tips

1. If you want add-ins to share Ribbon elements, use the idQ and xlmns: keyword. In my example, the Chart Tools.xlam and Priveleged UDFs.xlam both have access to the elements with idQ's equal to x:chartToolsTab and x:privelgedUDFsTab. For this to work, the x: is required, and, I've defined its namespace in the first line of my customUI.xml file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.
2. If you want add-ins to access Ribbon elements shipped with Excel, use the isMSO keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.

If it's a PHP issue, you could simply alter the configuration file php.ini wherever it's located and update the settings for PORT/SOCKET-PATH etc to make it connect to the server.

In my case, I opened the file php.ini and did

mysql.default_socket = /var/run/mysqld/mysqld.sock
mysqli.default_socket = /var/run/mysqld/mysqld.sock

And it worked straight away. I have to admit, I took hint from the accepted answer by @Joni

You also need to configure and start the MySQL server. This will probably help

The following will return true if two Calendar variables have the same day of the year.

  public boolean isSameDay(Calendar c1, Calendar c2){
    final int DAY=1000*60*60*24;
    return ((c1.getTimeInMillis()/DAY)==(c2.getTimeInMillis()/DAY));
  } // end isSameDay

In Apache 2.4, the authorization configuration syntax has changed, and the Order, Deny or Allow directives should no longer be used.

The new way to do this would be:

<VirtualHost *:8080>
    <Location />
        Require ip 192.168.1.0
    </Location>
    ...
</VirtualHost>

Further examples using the new syntax can be found in the Apache documentation: Upgrading to 2.4 from 2.2

An updated answer to this question would be the following :

"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -latest -property productId

Resolves to 2019

"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -latest -property catalog_productLineVersion

Resolves to Microsoft.VisualStudio.Product.Professional

In Angular $http case, the success() and error() function will have response object been unwrapped, so the callback signature would be like $http(...).success(function(data, status, headers, config))

for then(), you probably will deal with the raw response object. such as posted in AngularJS $http API document

$http({
        url: $scope.url,
        method: $scope.method,
        cache: $templateCache
    })
    .success(function(data, status) {
        $scope.status = status;
        $scope.data = data;
    })
    .error(function(data, status) {
        $scope.data = data || 'Request failed';
        $scope.status = status;
    });

The last .catch(...) will not need unless there is new error throw out in previous promise chain.

All of the answers are good but not complete. Use this.

 <EditText

Use a subquery in the where clause. For a delete query requirig a join, this example will delete rows that are unmatched in the joined table "docx_document" and that have a create date > 120 days in the "docs_documents" table.

delete from docs_documents d
where d.id in (
    select a.id from docs_documents a
    left join docx_document b on b.id = a.document_id
    where b.id is null
        and floor(sysdate - a.create_date) > 120
 );

1. Pick a random number between [0, x), where x is the number of different symbols. Hopefully the choice is uniformly chosen and not predictable :-)

2. Now choose the symbol representing x.

3. Profit!

I would start reading up Pseudorandomness and then some common Pseudo-random number generators. Of course, your language hopefully already has a suitable "random" function :-)

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

 public interface IService { 

  String BASE_URL = "https://api.demo.com/";

  @GET("Login") //i.e https://api.demo.com/Search? 
  Call<Products> getUserDetails(@Query("email") String emailID, @Query("password") String password)

} 

It will be called this way. Considering you did the rest of the code already.

Call<Results> call = service.getUserDetails("[email protected]", "Password@123");

For example when a query is returned, it will look like this.

https://api.demo.com/[email protected]&password=Password@123

How to use in or out or ref in C#?

• All keywords in C# have the same functionality but with some boundaries.
• in arguments cannot be modified by the called method.
• ref arguments may be modified.
• ref must be initialized before being used by caller it can be read and updated in the method.
• out arguments must be modified by the caller.
• out arguments must be initialized in the method
• Variables passed as in arguments must be initialized before being passed in a method call. However, the called method may not assign a value or modify the argument.

You can't use the in, ref, and out keywords for the following kinds of methods:

• Async methods, which you define by using the async modifier.
• Iterator methods, which include a yield return or yield break statement.

How about using a library like momentjs by writing a script like this:

[install_moment.js]
function get_moment(){
    // shim to get UMD module to load as CommonJS
    var module = {exports:{}};

    /* 
    copy your favorite UMD module (i.e. moment.js) here
    */

    return module.exports
}
//load the module generator into the stored procedures: 
db.system.js.save( {
        _id:"get_moment",
        value: get_moment,
    });

Then load the script at the command line like so:

> mongo install_moment.js

Finally, in your next mongo session, use it like so:

// LOAD STORED PROCEDURES
db.loadServerScripts();

// GET THE MOMENT MODULE
var moment = get_moment();

// parse a date-time string
var a = moment("23 Feb 1997 at 3:23 pm","DD MMM YYYY [at] hh:mm a");

// reformat the string as you wish:
a.format("[The] DDD['th day of] YYYY"): //"The 54'th day of 1997"

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

If you need an independent environment for your project: Install your environment to your project folder using the --prefix option:

conda create --prefix C:\your\workspace\root\awesomeEnv\ python=3

In VSCode launch.json configuration set your "pythonPath" to:

"pythonPath":"${workspaceRoot}/awesomeEnv/python.exe"

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

Try the __length_hint__() method from any iterator object:

iter(...).__length_hint__() > 0

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

In my case, it took some digging, but found it.

My Context

I'm looking at exception/error logs from the website using Elmah. Elmah returns the state of the server at the of time the exception, in the form of a large XML document. For our reporting engine I pretty-print the XML with XmlWriter.

During a website attack, I noticed that some xmls weren't parsing and was receiving this '.', hexadecimal value 0x00, is an invalid character. exception.

NON-RESOLUTION: I converted the document to a byte[] and sanitized it of 0x00, but it found none.

When I scanned the xml document, I found the following:

...
<form>
...
<item name="SomeField">
   <value
     string="C:\boot.ini&#x0;.htm" />
 </item>
...

There was the nul byte encoded as an html entity � !!!

RESOLUTION: To fix the encoding, I replaced the � value before loading it into my XmlDocument, because loading it will create the nul byte and it will be difficult to sanitize it from the object. Here's my entire process:

XmlDocument xml = new XmlDocument();
details.Xml = details.Xml.Replace("�", "[0x00]");  // in my case I want to see it, otherwise just replace with ""
xml.LoadXml(details.Xml);

string formattedXml = null;

// I have this in a helper function, but for this example I have put it in-line
StringBuilder sb = new StringBuilder();
XmlWriterSettings settings = new XmlWriterSettings {
    OmitXmlDeclaration = true,
    Indent = true,
    IndentChars = "\t",
    NewLineHandling = NewLineHandling.None,
};
using (XmlWriter writer = XmlWriter.Create(sb, settings)) {
    xml.Save(writer);
    formattedXml = sb.ToString();
}

LESSON LEARNED: sanitize for illegal bytes using the associated html entity, if your incoming data is html encoded on entry.

Here is a really elegant solution from Chris Thielen ui-router-extras: $previousState

var previous = $previousState.get(); //Gets a reference to the previous state.

previous is an object that looks like: { state: fromState, params: fromParams } where fromState is the previous state and fromParams is the previous state parameters.

As per this paper Finding the Kth largest item in a list of n items the following algorithm will take O(n) time in worst case.

1. Divide the array in to n/5 lists of 5 elements each.
2. Find the median in each sub array of 5 elements.
3. Recursively ?nd the median of all the medians, lets call it M
4. Partition the array in to two sub array 1st sub-array contains the elements larger than M , lets say this sub-array is a1 , while other sub-array contains the elements smaller then M., lets call this sub-array a2.
5. If k <= |a1|, return selection (a1,k).
6. If k- 1 = |a1|, return M.
7. If k> |a1| + 1, return selection(a2,k -a1 - 1).

Analysis: As suggested in the original paper:

We use the median to partition the list into two halves(the first half, if k <= n/2 , and the second half otherwise). This algorithm takes time cn at the first level of recursion for some constant c, cn/2 at the next level (since we recurse in a list of size n/2), cn/4 at the third level, and so on. The total time taken is cn + cn/2 + cn/4 + .... = 2cn = o(n).

Why partition size is taken 5 and not 3?

As mentioned in original paper:

Dividing the list by 5 assures a worst-case split of 70 - 30. Atleast half of the medians greater than the median-of-medians, hence atleast half of the n/5 blocks have atleast 3 elements and this gives a 3n/10 split, which means the other partition is 7n/10 in worst case. That gives T(n) = T(n/5)+T(7n/10)+O(n). Since n/5+7n/10 < 1, the worst-case running time isO(n).

Now I have tried to implement the above algorithm as:

public static int findKthLargestUsingMedian(Integer[] array, int k) {
        // Step 1: Divide the list into n/5 lists of 5 element each.
        int noOfRequiredLists = (int) Math.ceil(array.length / 5.0);
        // Step 2: Find pivotal element aka median of medians.
        int medianOfMedian =  findMedianOfMedians(array, noOfRequiredLists);
        //Now we need two lists split using medianOfMedian as pivot. All elements in list listOne will be grater than medianOfMedian and listTwo will have elements lesser than medianOfMedian.
        List<Integer> listWithGreaterNumbers = new ArrayList<>(); // elements greater than medianOfMedian
        List<Integer> listWithSmallerNumbers = new ArrayList<>(); // elements less than medianOfMedian
        for (Integer element : array) {
            if (element < medianOfMedian) {
                listWithSmallerNumbers.add(element);
            } else if (element > medianOfMedian) {
                listWithGreaterNumbers.add(element);
            }
        }
        // Next step.
        if (k <= listWithGreaterNumbers.size()) return findKthLargestUsingMedian((Integer[]) listWithGreaterNumbers.toArray(new Integer[listWithGreaterNumbers.size()]), k);
        else if ((k - 1) == listWithGreaterNumbers.size()) return medianOfMedian;
        else if (k > (listWithGreaterNumbers.size() + 1)) return findKthLargestUsingMedian((Integer[]) listWithSmallerNumbers.toArray(new Integer[listWithSmallerNumbers.size()]), k-listWithGreaterNumbers.size()-1);
        return -1;
    }

    public static int findMedianOfMedians(Integer[] mainList, int noOfRequiredLists) {
        int[] medians = new int[noOfRequiredLists];
        for (int count = 0; count < noOfRequiredLists; count++) {
            int startOfPartialArray = 5 * count;
            int endOfPartialArray = startOfPartialArray + 5;
            Integer[] partialArray = Arrays.copyOfRange((Integer[]) mainList, startOfPartialArray, endOfPartialArray);
            // Step 2: Find median of each of these sublists.
            int medianIndex = partialArray.length/2;
            medians[count] = partialArray[medianIndex];
        }
        // Step 3: Find median of the medians.
        return medians[medians.length / 2];
    }

Just for sake of completion, another algorithm makes use of Priority Queue and takes time O(nlogn).

public static int findKthLargestUsingPriorityQueue(Integer[] nums, int k) {
        int p = 0;
        int numElements = nums.length;
        // create priority queue where all the elements of nums will be stored
        PriorityQueue<Integer> pq = new PriorityQueue<Integer>();

        // place all the elements of the array to this priority queue
        for (int n : nums) {
            pq.add(n);
        }

        // extract the kth largest element
        while (numElements - k + 1 > 0) {
            p = pq.poll();
            k++;
        }

        return p;
    }

Both of these algorithms can be tested as:

public static void main(String[] args) throws IOException {
        Integer[] numbers = new Integer[]{2, 3, 5, 4, 1, 12, 11, 13, 16, 7, 8, 6, 10, 9, 17, 15, 19, 20, 18, 23, 21, 22, 25, 24, 14};
        System.out.println(findKthLargestUsingMedian(numbers, 8));
        System.out.println(findKthLargestUsingPriorityQueue(numbers, 8));
    }

As expected output is: 18 18

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

I understand this is an old question, still sharing an information. In Visual Studio 2017, you can just right click on the solution file and select Add solution to source control

This will add two files to your source folder.

1. .gitattributes
2. .gitignore

This is the easiest way.

No, there is no way to comment a line in XML and have the comment end automatically on a linebreak.

XML has only one definition for a comment:

'<!--' ((Char - '-') | ('-' (Char - '-')))* '-->'

XML forbids -- in comments to maintain compatibility with SGML.

Just another way to retrieve the same data using INFORMATION_SCHEMA

The information schema views included in SQL Server comply with the ISO standard definition for the INFORMATION_SCHEMA.

If you don't see the web.xml file in WEB-INF folder,

- Select Deployment Descriptor and right click on it.
- Then select the Generate Deployment Descriptor Stub

Finally you get web.xml file.

But if i take the piece of sql and run it from sql management studio, it will run without issue.

If you are at liberty to, change the service account to your own login, which would inherit your language/regional perferences.

The real crux of the issue is:

I use the following to convert -> date.Value.ToString("MM/dd/yyyy HH:mm:ss")

Please start using parameterized queries so that you won't encounter these issues in the future. It is also more robust, predictable and best practice.

Try this Simple Steps....

NOTE: Please check device location latitude & logitude if you are using simulator means. By defaults its none only.

Step 1: Import CoreLocation framework in .h File

#import <CoreLocation/CoreLocation.h>

Step 2: Add delegate CLLocationManagerDelegate

@interface yourViewController : UIViewController<CLLocationManagerDelegate>
{
    CLLocationManager *locationManager;
    CLLocation *currentLocation;
}

Step 3: Add this code in class file

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self CurrentLocationIdentifier]; // call this method
}

Step 4: Method to detect current location

//------------ Current Location Address-----
-(void)CurrentLocationIdentifier
{
    //---- For getting current gps location
    locationManager = [CLLocationManager new];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation];
    //------
}

Step 5: Get location using this method

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    currentLocation = [locations objectAtIndex:0];
    [locationManager stopUpdatingLocation];
    CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
    [geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if (!(error))
         {
             CLPlacemark *placemark = [placemarks objectAtIndex:0];
             NSLog(@"\nCurrent Location Detected\n");
             NSLog(@"placemark %@",placemark);
             NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
             NSString *Address = [[NSString alloc]initWithString:locatedAt];
             NSString *Area = [[NSString alloc]initWithString:placemark.locality];
             NSString *Country = [[NSString alloc]initWithString:placemark.country];
             NSString *CountryArea = [NSString stringWithFormat:@"%@, %@", Area,Country];
             NSLog(@"%@",CountryArea);
         }
         else
         {
             NSLog(@"Geocode failed with error %@", error);
             NSLog(@"\nCurrent Location Not Detected\n");
             //return;
             CountryArea = NULL;
         }
         /*---- For more results 
         placemark.region);
         placemark.country);
         placemark.locality); 
         placemark.name);
         placemark.ocean);
         placemark.postalCode);
         placemark.subLocality);
         placemark.location);
          ------*/
     }];
}

Spinning off the closing question, "how do I convert a to type Test::A" rather than being rigid about the requirement to have a cast in there, and answering several years late only because this seems to be a popular question and nobody else has mentioned the alternative, per the C++11 standard:

5.2.9 Static cast

... an expression e can be explicitly converted to a type T using a static_cast of the form static_cast<T>(e) if the declaration T t(e); is well-formed, for some invented temporary variable t (8.5). The effect of such an explicit conversion is the same as performing the declaration and initialization and then using the temporary variable as the result of the conversion.

Therefore directly using the form t(e) will also work, and you might prefer it for neatness:

auto result = Test(a);

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

you will almost never get these codes in practice so this code is pretty much pointless

You have $headers .= '...'; followed by $headers = '...';; the second line is overwriting the first.

Just put the $headers .= "Bcc: $emailList\r\n"; say after the Content-type line and it should be fine.

On a side note, the To is generally required; mail servers might mark your message as spam otherwise.

$headers  = "From: [email protected]\r\n" .
  "X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";

Create a tensor on the GPU as follows:

$ python

I found json_reformat to be very handy. So I just did the following:

curl http://127.0.0.1:5000/people/api.json | json_reformat

that's it!

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();

It means one of your arrays isn't actually an array.

By the way, your if check is unnecessary. If $varsCount is 0 the for loop won't execute anyway.

BalusC answer didn't work for me (bash console on Ubuntu). Some stuff remained at the end of the line. So I rolled over again with spaces. Thread.sleep() is used in the below snippet so you can see what's happening.

String foo = "the quick brown fox jumped over the fence";
System.out.printf(foo);
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul("\b", foo.length()));
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul(" ", foo.length()));
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul("\b", foo.length()));

where mul is a simple method defined as:

private static String mul(String s, int n) {
    StringBuilder builder = new StringBuilder();
    for (int i = 0; i < n ; i++)
        builder.append(s);
    return builder.toString();
}

(Guava's Strings class also provides a similar repeat method)

The nearest equivalents would be icode and bcode as used by scalac, view Miguel Garcia's site on the Scalac optimiser for more information, here: http://magarciaepfl.github.io/scala/

You might also consider Java bytecode itself to be your intermediate representation, given that bytecode is the ultimate output of scalac.

Or perhaps the true intermediate is something that the JIT produces before it finally outputs native instructions?

Ultimately though... There's no single place that you can point at an claim "there's the intermediate!". Scalac works in phases that successively change the abstract syntax tree, every single phase produces a new intermediate. The whole thing is like an onion, and it's very hard to try and pick out one layer as somehow being more significant than any other.

For iOS SWift 4

button.layer.cornerRadius = 25;
button.layer.masksToBounds = true;

Instead of using np.hist2d, which in general produces quite ugly histograms, I would like to recycle py-sphviewer, a python package for rendering particle simulations using an adaptive smoothing kernel and that can be easily installed from pip (see webpage documentation). Consider the following code, which is based on the example:

import numpy as np
import numpy.random
import matplotlib.pyplot as plt
import sphviewer as sph

def myplot(x, y, nb=32, xsize=500, ysize=500):   
    xmin = np.min(x)
    xmax = np.max(x)
    ymin = np.min(y)
    ymax = np.max(y)

    x0 = (xmin+xmax)/2.
    y0 = (ymin+ymax)/2.

    pos = np.zeros([len(x),3])
    pos[:,0] = x
    pos[:,1] = y
    w = np.ones(len(x))

    P = sph.Particles(pos, w, nb=nb)
    S = sph.Scene(P)
    S.update_camera(r='infinity', x=x0, y=y0, z=0, 
                    xsize=xsize, ysize=ysize)
    R = sph.Render(S)
    R.set_logscale()
    img = R.get_image()
    extent = R.get_extent()
    for i, j in zip(xrange(4), [x0,x0,y0,y0]):
        extent[i] += j
    print extent
    return img, extent
    
fig = plt.figure(1, figsize=(10,10))
ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(222)
ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)


# Generate some test data
x = np.random.randn(1000)
y = np.random.randn(1000)

#Plotting a regular scatter plot
ax1.plot(x,y,'k.', markersize=5)
ax1.set_xlim(-3,3)
ax1.set_ylim(-3,3)

heatmap_16, extent_16 = myplot(x,y, nb=16)
heatmap_32, extent_32 = myplot(x,y, nb=32)
heatmap_64, extent_64 = myplot(x,y, nb=64)

ax2.imshow(heatmap_16, extent=extent_16, origin='lower', aspect='auto')
ax2.set_title("Smoothing over 16 neighbors")

ax3.imshow(heatmap_32, extent=extent_32, origin='lower', aspect='auto')
ax3.set_title("Smoothing over 32 neighbors")

#Make the heatmap using a smoothing over 64 neighbors
ax4.imshow(heatmap_64, extent=extent_64, origin='lower', aspect='auto')
ax4.set_title("Smoothing over 64 neighbors")

plt.show()

which produces the following image:

As you see, the images look pretty nice, and we are able to identify different substructures on it. These images are constructed spreading a given weight for every point within a certain domain, defined by the smoothing length, which in turns is given by the distance to the closer nb neighbor (I've chosen 16, 32 and 64 for the examples). So, higher density regions typically are spread over smaller regions compared to lower density regions.

The function myplot is just a very simple function that I've written in order to give the x,y data to py-sphviewer to do the magic.

While on dealing with the SimpleDateFormat class, it's important to remember that Date is not thread-safe and you can not share a single Date object with multiple threads.

Also there is big difference between "m" and "M" where small case is used for minutes and capital case is used for month. The same with "d" and "D". This can cause subtle bugs which often get overlooked. See Javadoc or Guide to Convert String to Date in Java for more details.

As well as the already mentioned @Html.Raw(string) approach, if you output an MvcHtmlString it will not be encoded. This can be useful when adding your own extensions to the HtmlHelper, or when returning a value from your view model that you know may contain html.

For example, if your view model was:

public class SampleViewModel
{
  public string SampleString { get; set; }
  public MvcHtmlString SampleHtmlString { get; set; }
}

For Core 1.0+ (and MVC 5+) use HtmlString

public class SampleViewModel
{
  public string SampleString { get; set; }
  public HtmlString SampleHtmlString { get; set; }
}

then

<!-- this will be encoded -->
<div>@Model.SampleString</div>
<!-- this will not be encoded -->
<div>@Html.Raw(Model.SampleString)</div>
<!-- this will not be encoded either -->
<div>@Model.SampleHtmlString</div>

Press Alt + Enter with the cursor on top of the import. The Optimize imports menu will show. Press Enter again. Your unused imports will be removed.

For the php_intl.dll extension to work correctly, you need to have the following files in a folder in your PATH:

• icudt36.dll
• icuin36.dll
• icuio36.dll
• icule36.dll
• iculx36.dll
• icutu36.dll
• icuuc36.dll

By default they're sitting in your PHP directory, but that directory isn't necessarily in your PATH (it wasn't for me, using xampp)

This has to be in your global path, not just your user's path. To set the global path, go to system info (windows key + PAUSE), then Advanced System Settings (Vista+) or Advanced (XP) and click the "Environment Variables" button and add the appropriate directory to the PATH variable in the System Variables list.

Lo-Dash, which extends Underscore, has findIndex method, that can find the index of a given instance, or by a given predicate, or according to the properties of a given object.

In your case, I would do:

var index = _.findIndex(tv, { id: voteID });

Give it a try.

There's no "direct" way of doing so but you can specify the pattern twice as in: a[^a]*a that match up to the second "a".

The alternative is to use your programming language (perl? C#? ...) to match the first occurence and then the second one.

EDIT: I've seen other responded using the "non-greedy" operators which might be a good way to go, assuming you have them in your regex library!

No need to use select just use [ instead

data[,grepl("search_string", colnames(data))]

Let's try with iris dataset

>iris[,grepl("Sepal", colnames(iris))]
  Sepal.Length Sepal.Width
1          5.1         3.5
2          4.9         3.0
3          4.7         3.2
4          4.6         3.1
5          5.0         3.6
6          5.4         3.9

Close buffer without closing the window

If you want to close a buffer without destroying your window layout (current layout based on splits), you can use a Plugin like bbye. Based on this, you can just use

:Bdelete (instead of :bdelete)
:Bwipeout (instead of :bwipeout)

Or just create a mapping in your .vimrc for easier access like

:nnoremap <Leader>q :Bdelete<CR>

Advantage over vim's :bdelete and :bwipeout

From the plugin's documentation:

• Close and remove the buffer.
• Show another file in that window.
• Show an empty file if you've got no other files open.
• Do not leave useless [no file] buffers if you decide to edit another file in that window.
• Work even if a file's open in multiple windows.
• Work a-okay with various buffer explorers and tabbars.

:bdelete vs :bwipeout

From the plugin's documentation:

Vim has two commands for closing a buffer: :bdelete and :bwipeout. The former removes the file from the buffer list, clears its options, variables and mappings. However, it remains in the jumplist, so Ctrl-o takes you back and reopens the file. If that's not what you want, use :bwipeout or Bbye's equivalent :Bwipeout where you would've used :bdelete.

SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS 
   (SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)

or

SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN 
    (SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)

or

SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B 
    ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL

Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

Check, if you are not accidentally requesting HTTPS protocol instead of HTTP.

I have overlooked that I was requesting https://localhost:... instead of http://localhost:... and it resulted to this weird message..

There can only be one Access-Control-Allow-Origin response header, and that header can only have one origin value. Therefore, in order to get this to work, you need to have some code that:

1. Grabs the Origin request header.
2. Checks if the origin value is one of the whitelisted values.
3. If it is valid, sets the Access-Control-Allow-Origin header with that value.

I don't think there's any way to do this solely through the web.config.

if (ValidateRequest()) {
    Response.Headers.Remove("Access-Control-Allow-Origin");
    Response.AddHeader("Access-Control-Allow-Origin", Request.UrlReferrer.GetLeftPart(UriPartial.Authority));

    Response.Headers.Remove("Access-Control-Allow-Credentials");
    Response.AddHeader("Access-Control-Allow-Credentials", "true");

    Response.Headers.Remove("Access-Control-Allow-Methods");
    Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
}

To check for local differences:

git diff myfile.txt

or you can use a diff tool (in case you'd like to revert some changes):

git difftool myfile.txt

^{To use git difftool more efficiently, install and use your favourite GUI tool such as Meld, DiffMerge or OpenDiff.}

Note: You can also use . (instead of filename) to see current dir changes.

In order to check changes per each line, use: git blame which will display which line was commited in which commit.

To view the actual file before the commit (where master is your branch), run:

git show master:path/my_file

You don't need to use

adb shell getevent -l

command, you just need to enable in Developer Options on the device [Show Touch data] to get X and Y.

With css, a table can have padding independently of its cells.

The padding property is not inherited by its children.

So, defining:

table {
    padding: 5px;
}

Should work. You could also specifically tell the browser how to pad (or in this case, not pad) your cells.

td {
    padding: 0px;
}

EDIT: Not supported by IE8. Sorry.

In C# one easy way is to mark the ones you wish to delete then create a new list to iterate over...

foreach(var item in list.ToList()){if(item.Delete) list.Remove(item);}  

or even simpler use linq....

list.RemoveAll(p=>p.Delete);

but it is worth considering if other tasks or threads will have access to the same list at the same time you are busy removing, and maybe use a ConcurrentList instead.

My personal preference is to work with pathlib objects - it offers a more pythonic and less error-prone way to interact with the filesystem, especially if You develop cross-platform code.

In that case, You might use pathlib3x - it offers a backport of the latest (at the date of writing this answer Python 3.10.a0) Python pathlib for Python 3.6 or newer, and a few additional functions like "copy", "copy2", "copytree", "rmtree" etc ...

It also wraps shutil.rmtree:

$> python -m pip install pathlib3x
$> python
>>> import pathlib3x as pathlib

# delete a directory tree
>>> my_dir_to_delete=pathlib.Path('c:/temp/some_dir')
>>> my_dir_to_delete.rmtree(ignore_errors=True)

# delete a file
>>> my_file_to_delete=pathlib.Path('c:/temp/some_file.txt')
>>> my_file_to_delete.unlink(missing_ok=True)

you can find it on github or PyPi

^{Disclaimer: I'm the author of the pathlib3x library.}

Finalize is the backstop method, called by the garbage collector when it reclaims an object. Dispose is the "deterministic cleanup" method, called by applications to release valuable native resources (window handles, database connections, etc.) when they are no longer needed, rather than leaving them held indefinitely until the GC gets round to the object.

As the user of an object, you always use Dispose. Finalize is for the GC.

As the implementer of a class, if you hold managed resources that ought to be disposed, you implement Dispose. If you hold native resources, you implement both Dispose and Finalize, and both call a common method that releases the native resources. These idioms are typically combined through a private Dispose(bool disposing) method, which Dispose calls with true, and Finalize calls with false. This method always frees native resources, then checks the disposing parameter, and if it is true it disposes managed resources and calls GC.SuppressFinalize.

opacity on parent element sets it for the whole sub DOM tree

You can't really set opacity for certain element that wouldn't cascade to descendants as well. That's not how CSS opacity works I'm afraid.

What you can do is to have two sibling elements in one container and set transparent one's positioning:

<div id="container">
    <div id="transparent"></div>
    <div id="content"></div>
</div>

then you have to set transparent position: absolute/relative so its content sibling will be rendered over it.

rgba can do background transparency of coloured backgrounds

rgba colour setting on element's background-color will of course work, but it will limit you to only use colour as background. No images I'm afraid. You can of course use CSS3 gradients though if you provide gradient stop colours in rgba. That works as well.

But be advised that rgba may not be supported by your required browsers.

Alert-free modal dialog functionality

But if you're after some kind of masking the whole page, this is usually done by adding a separate div with this set of styles:

position: fixed;
width: 100%;
height: 100%;
z-index: 1000; /* some high enough value so it will render on top */
opacity: .5;
filter: alpha(opacity=50);

Then when you display the content it should have a higher z-index. But these two elements are not related in terms of siblings or anything. They're just displayed as they should be. One over the other.

UPDATE user_account student

SET (student.student_education_facility_id) = (

   SELECT teacher.education_facility_id

   FROM user_account teacher

   WHERE teacher.user_account_id = student.teacher_id AND teacher.user_type = 'ROLE_TEACHER'

)

WHERE student.user_type = 'ROLE_STUDENT';

EDIT: As pointed out in the comment, itoa() is not a standard, so better use sprintf() approach suggested in the rivaling answer!

You can use itoa() function to convert your integer value to a string.

Here is an example:

int num = 321;
char snum[5];

// convert 123 to string [buf]
itoa(num, snum, 10);

// print our string
printf("%s\n", snum);

If you want to output your structure into a file there is no need to convert any value beforehand. You can just use the printf format specification to indicate how to output your values and use any of the operators from printf family to output your data.

For Python 3.x

import urllib.request
from urllib.error import HTTPError
try:
    urllib.request.urlretrieve(url, fullpath)
except urllib.error.HTTPError as err:
    print(err.code)

I have the same problem. I wonder if it is possible to create the HTML for printing via a jquery plugin: http://www.recoding.it/?p=138

Then send the HTML to a php script (using an ajax call), generate a pdf with http://www.xhtml2pdf.com/ or http://code.google.com/p/wkhtmltopdf/.

Afterwards the pdf could be displayed (by setting the appropriate content type and direct rendering) or displayed by a http-Redirect to the generated pdf.

The generated pdfs in the pfd_for_printing-folder could act as cache and be deleted by a job once a day.

In addition to @Khanetor's answer, for those who are working with cross-origin requests: credentials: 'include'

Sample JSON fetch request:

fetch(url, {
  method: 'GET',
  credentials: 'include'
})
  .then((response) => response.json())
  .then((json) => {
    console.log('Gotcha');
  }).catch((err) => {
    console.log(err);
});

You can set height and width like this also:

viewinstance.setLayoutParams(new LayoutParams(width, height));

Kindly try below on postman :-

The key part is that I am reducing the scope of the problem: I forbid indirect execution of the script via the path (as in /bin/sh [script path relative to path component]).

This can be detected because $0 will be a relative path which does not resolve to any file relative to the current folder. I believe that direct execution using the #! mechanism always results in an absolute $0, including when the script is found on the path.

I also require that the pathname and any pathnames along a chain of symbolic links only contain a reasonable subset of characters, notably not \n, >, * or ?. This is required for the parsing logic.

There are a few more implicit expectations which I will not go into (look at this answer), and I do not attempt to handle deliberate sabotage of $0 (so consider any security implications). I expect this to work on almost any Unix-like system with a Bourne-like /bin/sh.

#!/bin/sh
(
    path="${0}"
    while test -n "${path}"; do
        # Make sure we have at least one slash and no leading dash.
        expr "${path}" : / > /dev/null || path="./${path}"
        # Filter out bad characters in the path name.
        expr "${path}" : ".*[*?<>\\]" > /dev/null && exit 1
        # Catch embedded new-lines and non-existing (or path-relative) files.
        # $0 should always be absolute when scripts are invoked through "#!".
        test "`ls -l -d "${path}" 2> /dev/null | wc -l`" -eq 1 || exit 1
        # Change to the folder containing the file to resolve relative links.
        folder=`expr "${path}" : "\(.*/\)[^/][^/]*/*$"` || exit 1
        path=`expr "x\`ls -l -d "${path}"\`" : "[^>]* -> \(.*\)"`
        cd "${folder}"
        # If the last path was not a link then we are in the target folder.
        test -n "${path}" || pwd
    done
)

Using inline styles:

<input type="text" style="text-align: right"/>

or, put it in a style sheet, like so:

<style>
   .rightJustified {
        text-align: right;
    }
</style>

and reference the class:

<input type="text" class="rightJustified"/>

This solution is only for components

If we toggle(show/hide) components using booleans then data is also removed. No need to clean the form fields.

I usually make components and initialize them using booleans. e.g.

<template>
    <button @click="show_create_form = true">Add New Record</button
    <create-form v-if="show_create_form" />
</template>


<script>
...
data(){
   return{
       show_create_form:false //making it false by default
   }
},
methods:{
    submitForm(){
      //...
      this.axios.post('/submit-form-url',data,config)
           .then((response) => {
               this.show_create_form= false; //hide it again after success.
               //if you now click on add new record button then it will show you empty form
           }).catch((error) => {
              //
           })
    }
}
...
</script>

When use clicks on edit button then this boolean becomes true and after successful submit I change it to false again.

yeah it works for me as well.

Note : we need to use window.parent.document

    $("button", window.parent.document).click(function()
    {
        alert("Functionality defined by def");
    });

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

Without changing Environment Variables, You can manage java version based on the project level by using Maven Compiler Plugin.

There are so many reasons for this error. My reason is : the version of pyspark is incompatible with spark. pyspark version :2.4.0, but spark version is 2.2.0. it always cause python always fail when starting spark process. then spark cannot tell its ports to python. so error will be "Pyspark: Exception: Java gateway process exited before sending the driver its port number ".

I suggest you dive into source code to find out the real reasons when this error happens

Save this class in the file StaticDemo.java. Also you cant have more than one public classes in one file.

easy way to use Aquery library it helps to get direct load image from url

AQuery aq=new AQuery(this); // intsialze aquery
 aq.id(R.id.ImageView).image("http://www.vikispot.com/z/images/vikispot/android-w.png");

There is a simple way.

1. You create an iframe which have for source something like "http://your-domain.com/index.php?url=http://the-site-you-want-to-get.com/unicorn

2. Then, you just get this url with $_GET and display the contents with file_get_contents($_GET['url']);

You will obtain an iframe which has a domain same than yours, then you will be able to use the $("iframe").contents().find("body") to manipulate the content.

All those who can't install perldoc, or other modules, and want to know what modules are available (CPAN or otherwise), the following works for linux and Mingw32/64:

grep -RhIP '^package [A-Z][\w:]+;' `perl -e 'print join " ",@INC'` | sed 's/package //' | sort | uniq

Yes, it's messy. Yes, it probably reports more than you want. But if you pipe it into a file, you can easily check for, say, which dbm interfaces are present:

 grep -RhIP '^package [A-Z][\w:]+;' `perl -e 'print join " ",@INC'` | sed 's/package //' | sort | uniq > modules-installed

(I realise this doesn't answer the OP's question exactly, but I'm posting it for anybody who ended up here for the same reason I did. That's the problem with stack*** it's almost imposisble to find the question you're asking, even when it exists, yet stack*** is nearly always google's top hit!)

If you want to really look at what is going on in the VM memory you should use a good tool like VisualVM. This is Free Software and it's a great way to see what is going on.

Nothing is really "wrong" with explicit gc() calls. However, remember that when you call gc() you are "suggesting" that the garbage collector run. There is no guarantee that it will run at the exact time you run that command.

For short queries that can fit on one or two lines, I use the string literal solution in the top-voted solution above. For longer queries, I break them out to .sql files. I then use a wrapper function to load the file and execute the script, something like:

script_cache = {}
def execute_script(cursor,script,*args,**kwargs):
    if not script in script_cache:
        with open(script,'r') as s:
            script_cache[script] = s
    return cursor.execute(script_cache[script],*args,**kwargs)

Of course this often lives inside a class so I don't usually have to pass cursor explicitly. I also generally use codecs.open(), but this gets the general idea across. Then SQL scripts are completely self-contained in their own files with their own syntax highlighting.

One example of rawQuery - db.rawQuery("select * from table where column = ?",new String[]{"data"});

What about just: :%s/\r//g That totally worked for me.

What this does is just to clean the end of line of all lines, it removes the ^M and that's it.

$( "#sortable" ).sortable({
    change: function(event, ui) {       
        var pos = ui.helper.index() < ui.placeholder.index() 
            ? { start: ui.helper.index(), end: ui.placeholder.index() }
            : { start: ui.placeholder.index(), end: ui.helper.index() }

        $(this)
            .children().removeClass( 'highlight' )
            .not( ui.helper ).slice( pos.start, pos.end ).addClass( 'highlight' );
    },
    stop: function(event, ui) {
        $(this).children().removeClass( 'highlight' );
    }
});

FIDDLE

An example of how it could be done inside change event without storing arbitrary data into element storage. Since the element where drag starts is ui.helper, and the element of current position is ui.placeholder, we can take the elements between those two indexes and highlight them. Also, we can use this inside handler since it refers to the element that the widget is attached. The example works with dragging in both directions.

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

This should get you there every single time.

background-image: url(<%= asset_data_uri 'transparent_2x2.png'%>);

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

copy this line and replace in your project

var myNewString = myOldString.replace ("username", visitorName);

there is a simple problem with coma (,)

I just had this same problem on Windows 7 64-bit. I ran console as administrator and deleted the .svn directory from the problem directory (got an error about logs or something, but ignored it). Then, in explorer, I deleted the problem directory which was no longer showing as under version control. Then, I ran an update and things proceeded as expected.

Most of the answers here are either 'UnSafe" or not LittleEndian safe. BitConverter is not LittleEndian safe. So building on an example in here (see the post by PZahra) I made a LittleEndian safe version simply by reading the byte array in reverse when BitConverter.IsLittleEndian == true

void Main(){    
    Console.WriteLine(BitConverter.IsLittleEndian); 
    byte[] bytes = BitConverter.GetBytes(0xdcbaabcdfffe1608);
    //Console.WriteLine(bytes); 
    string hexStr = ByteArrayToHex(bytes);
    Console.WriteLine(hexStr);
}

public static string ByteArrayToHex(byte[] data) 
{ 
   char[] c = new char[data.Length * 2]; 
   byte b; 
  if(BitConverter.IsLittleEndian)
  {
        //read the byte array in reverse
        for (int y = data.Length -1, x = 0; y >= 0; --y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }               
    }
    else
    {
        for (int y = 0, x = 0; y < data.Length; ++y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }
    }
    return String.Concat("0x",new string(c));
}

It returns this:

True
0xDCBAABCDFFFE1608

which is the exact hex that went into the byte array.

Update (20160519): Firebase just released a new feature called Firebase Storage. This allows you to upload images and other non-JSON data to a dedicated storage service. We highly recommend that you use this for storing images, instead of storing them as base64 encoded data in the JSON database.

You certainly can! Depending on how big your images are, you have a couple options:

1. For smaller images (under 10mb)

We have an example project that does that here: https://github.com/firebase/firepano

The general approach is to load the file locally (using FileReader) so you can then store it in Firebase just as you would any other data. Since images are binary files, you'll want to get the base64-encoded contents so you can store it as a string. Or even more convenient, you can store it as a data: url which is then ready to plop in as the src of an img tag (this is what the example does)!

2. For larger images

Firebase does have a 10mb (of utf8-encoded string data) limit. If your image is bigger, you'll have to break it into 10mb chunks. You're right though that Firebase is more optimized for small strings that change frequently rather than multi-megabyte strings. If you have lots of large static data, I'd definitely recommend S3 or a CDN instead.

I find until very useful with sleep. example:

> time = Time.now
> sleep 2.seconds until Time.now > time + 10.seconds # breaks when true
# or something like
> sleep 1.seconds until !req.loading # suggested by ohsully

As of today, you can read some values from HTML5 data attributes in CSS3 declarations. In CaioToOn's fiddle the CSS code can use the data properties for setting the content.

Unfortunately it is not working for the width and height (tested in Google Chrome 35, Mozilla Firefox 30 & Internet Explorer 11).

But there is a CSS3 attr() Polyfill from Fabrice Weinberg which provides support for data-width and data-height. You can find the GitHub repo to it here: cssattr.js.

You can use

Response.AddHeader("Content-disposition", "attachment; filename=" + Name);

Check out this example:

http://www.codeproject.com/KB/aspnet/textfile.aspx

This goes for ASP.NET. I am sure you can find similar solutions in all other server side languages. However there's no javascript solution to the best of my knowledge.

You'll do it the same way you would apply a css selector. For instanse you can do

$("#mydiv > .myclass")

or

$("#mydiv .myclass")

The last one will match every myclass inside myDiv, including myclass inside myclass.

A lambda function is an anonymous function that you create in-line. It can capture variables as some have explained, (e.g. http://www.stroustrup.com/C++11FAQ.html#lambda) but there are some limitations. For example, if there's a callback interface like this,

void apply(void (*f)(int)) {
    f(10);
    f(20);
    f(30);
}

you can write a function on the spot to use it like the one passed to apply below:

int col=0;
void output() {
    apply([](int data) {
        cout << data << ((++col % 10) ? ' ' : '\n');
    });
}

But you can't do this:

void output(int n) {
    int col=0;
    apply([&col,n](int data) {
        cout << data << ((++col % 10) ? ' ' : '\n');
    });
}

because of limitations in the C++11 standard. If you want to use captures, you have to rely on the library and

#include <functional> 

(or some other STL library like algorithm to get it indirectly) and then work with std::function instead of passing normal functions as parameters like this:

#include <functional>
void apply(std::function<void(int)> f) {
    f(10);
    f(20);
    f(30);
}
void output(int width) {
    int col;
    apply([width,&col](int data) {
        cout << data << ((++col % width) ? ' ' : '\n');
    });
}

You have two options:

1. Extend your .paging class definition:

   .paging:hover {
       border:1px solid #999;
       color:#000;
   }
   

2. Use the DOM hierarchy to apply the CSS style:

   div.paginate input:hover {
       border:1px solid #999;
       color:#000;
   }
   

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. .jpeg and .jpg files are identical. JPEG images are identified with 6 different standard file name extensions:

• .jpg
• .jpeg
• .jpe
• .jif
• .jfif
• .jfi

The jpg was used in Microsoft Operating Systems when they only supported 3 chars-extensions.

The JPEG File Interchange Format (JFIF - last three extensions in my list) is an image file format standard for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard, solving some of JIF's limitations in regard. Image data in JFIF files is compressed using the techniques in the JPEG standard, hence JFIF is sometimes referred to as "JPEG/JFIF".

Using the COUNT aggregate, you can first count how many rows there are and store in a variable called @cnt. Then you can compute parameters for the OFFSET-FETCH filter to specify, based on qty ordering, how many rows to skip (offset value) and how many to filter (fetch value).

The number of rows to skip is (@cnt - 1) / 2. It’s clear that for an odd count this calculation is correct because you first subtract 1 for the single middle value, before you divide by 2.

This also works correctly for an even count because the division used in the expression is integer division; so, when subtracting 1 from an even count, you’re left with an odd value.

When dividing that odd value by 2, the fraction part of the result (.5) is truncated. The number of rows to fetch is 2 - (@cnt % 2). The idea is that when the count is odd the result of the modulo operation is 1, and you need to fetch 1 row. When the count is even the result of the modulo operation is 0, and you need to fetch 2 rows. By subtracting the 1 or 0 result of the modulo operation from 2, you get the desired 1 or 2, respectively. Finally, to compute the median quantity, take the one or two result quantities, and apply an average after converting the input integer value to a numeric one as follows:

DECLARE @cnt AS INT = (SELECT COUNT(*) FROM [Sales].[production].[stocks]);
SELECT AVG(1.0 * quantity) AS median
FROM ( SELECT quantity
FROM [Sales].[production].[stocks]
ORDER BY quantity
OFFSET (@cnt - 1) / 2 ROWS FETCH NEXT 2 - @cnt % 2 ROWS ONLY ) AS D;

To copy formatting:

Range("F10").Select
Selection.Copy
Range("I10:J10").Select ' note that we select the whole merged cell
Selection.PasteSpecial Paste:=xlPasteFormats

copying the formatting will break the merged cells, so you can use this to put the cell back together

Range("I10:J10").Select
Selection.Merge

To copy a cell value, without copying anything else (and not using copy/paste), you can address the cells directly

Range("I10").Value = Range("F10").Value

other properties (font, color, etc ) can also be copied by addressing the range object properties directly in the same way

I learned python first by myself over a summer just by doing the tutorial on the python site (sadly, I don't seem to be able to find that anymore, so I can't post a link).

Later, python was taught to me in one of my first year courses at university. In the summer that followed, I practiced with PythonChallenge and with problems from Google Code Jam. Solving these problems help from an algorithmic perspective as well as from the perspective of learning what Python can do as well as how to manipulate it to get the fullest out of python.

For similar reasons, I have heard that code golf works as well, but i have never tried it for myself.

This is a slightly improvised answer to ajsp answer using XML-RPC.

On the server-side when you convert the data, convert the numpy data to a string using the '.tostring()' method. This encodes the numpy ndarray as bytes string. On the client-side when you receive the data decode it using '.fromstring()' method. I wrote two simple functions for this. Hope this is helpful.

1. ndarray2str -- Converts numpy ndarray to bytes string.
2. str2ndarray -- Converts binary str back to numpy ndarray.

    def ndarray2str(a):
        # Convert the numpy array to string 
        a = a.tostring()

        return a

On the receiver side, the data is received as a 'xmlrpc.client.Binary' object. You need to access the data using '.data'.

    def str2ndarray(a):
        # Specify your data type, mine is numpy float64 type, so I am specifying it as np.float64
        a = np.fromstring(a.data, dtype=np.float64)
        a = np.reshape(a, new_shape)

        return a

Note: Only problem with this approach is that XML-RPC is very slow while sending large numpy arrays. It took me around 4 secs to send and receive a (10, 500, 500, 3) size numpy array for me.

I am using python 3.7.4.

window.open(url, wndname, params), it has three arguments. if you don't want it open in the same window, just set a different wndname. such as :

window.open(url1, "name1", params); // this open one window or tab
window.open(url1, "name2", params); // though url is same, but it'll open in another window(tab).

Here is the details about window.open(), you can trust it!
https://developer.mozilla.org/en/DOM/window.open

I got the same error, and fixed it with the following PHP in my back-end script:

header('Access-Control-Allow-Origin: *');

header('Access-Control-Allow-Methods: GET, POST');

header("Access-Control-Allow-Headers: X-Requested-With");

You can use the substr function like this:

echo substr($myStr, 0, 5);

The second argument to substr is from what position what you want to start and third arguments is for how many characters you want to return.

I think it will be easy to you. I am using group_concat which concatenate diffent values with separator as we have defined

select ID,User, GROUP_CONCAT(Distinct Department order  by Department asc 

separator ', ') as Department from Table_Name   group by ID

Rails is deprecating the diff method.

For a quick one-liner:

hash1.to_s == hash2.to_s

Go to C:\xamppp\php. Set these values in php.ini:

upload_max_filesize = 1000M
post_max_size = 0M

In Apache 2.4, there's a new stock module called mod_ratelimit. For emulating modem speeds, you can use mod_dialup. Though I don't see why you just couldn't use mod_ratelimit for everything.

In the words of the master:

http://www.joelonsoftware.com/articles/Wrong.html

An interesting reading, as usual.

Extracts:

"Somebody, somewhere, read Simonyi’s paper, where he used the word “type,” and thought he meant type, like class, like in a type system, like the type checking that the compiler does. He did not. He explained very carefully exactly what he meant by the word “type,” but it didn’t help. The damage was done."

"But there’s still a tremendous amount of value to Apps Hungarian, in that it increases collocation in code, which makes the code easier to read, write, debug, and maintain, and, most importantly, it makes wrong code look wrong."

Make sure you have some time before reading Joel On Software. :)

Yes, but none of them will manage to produce readable enough code to worth the effort. You will spend more time trying to read the decompiled source with assembler blocks inside, than rewriting your old app from scratch.

For JS:

First, if you haven't installed telegram bot just install with the command

npm i messaging-api-telegram

Now, initialize its client with

const client = new TelegramClient({
    accessToken: process.env.<TELEGRAM_ACCESS_TOKEN>
});

Then, to send message use sendMessage() async function like below -

    const resp = await client.sendMessage(chatId, msg, {
        disableWebPagePreview: false,
        disableNotification: false,
        parseMode: "HTML"
    });

Here parse mode by default would be plain text but with parseOptions parseMode we can do 1. "HTML" and "MARKDOWN" to let use send messages in stylish way. Also get your access token of bot from telegram page and chatId or group chat Id from same.

Instead of the EndsWith function, I would choose to use the Path.GetExtension() method instead. Here is the full example:

var filteredFiles = Directory.EnumerateFiles( path )
.Where(
    file => Path.GetExtension(file).Equals( ".aspx", StringComparison.OrdinalIgnoreCase ) ||
            Path.GetExtension(file).Equals( ".ascx", StringComparison.OrdinalIgnoreCase ) );

or:

var filteredFiles = Directory.EnumerateFiles(path)
.Where(
    file => string.Equals( Path.GetExtension(file), ".aspx", StringComparison.OrdinalIgnoreCase ) ||
            string.Equals( Path.GetExtension(file), ".ascx", StringComparison.OrdinalIgnoreCase ) );

(Use StringComparison.OrdinalIgnoreCase if you care about performance: MSDN string comparisons)

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

I'v started preparing for Oracle 1z0-047 exam, validated against 12c While prepping for it i came across a 12c enhancement known as 'FETCH FIRST' It enables you to fetch rows /limit rows as per your convenience. Several options are available with it

- FETCH FIRST n ROWS ONLY
 - OFFSET n ROWS FETCH NEXT N1 ROWS ONLY // leave the n rows and display next N1 rows
 - n % rows via FETCH FIRST N PERCENT ROWS ONLY

Example:

Select * from XYZ a
order by a.pqr
FETCH FIRST 10 ROWS ONLY

Not clear where My_ConnectionString is coming from in your example, but try this

System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString

like this

Dim DBConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString)

While trace flag 272 may work for many, it definitely won't work for hosted Sql Server Express installations. So, I created an identity table, and use this through an INSTEAD OF trigger. I'm hoping this helps someone else, and/or gives others an opportunity to improve my solution. The last line allows returning the last identity column added. Since I typically use this to add a single row, this works to return the identity of a single inserted row.

The identity table:

CREATE TABLE [dbo].[tblsysIdentities](
[intTableId] [int] NOT NULL,
[intIdentityLast] [int] NOT NULL,
[strTable] [varchar](100) NOT NULL,
[tsConcurrency] [timestamp] NULL,
CONSTRAINT [PK_tblsysIdentities] PRIMARY KEY CLUSTERED 
(
    [intTableId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,  ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

and the insert trigger:

-- INSERT --
IF OBJECT_ID ('dbo.trgtblsysTrackerMessagesIdentity', 'TR') IS NOT NULL
   DROP TRIGGER dbo.trgtblsysTrackerMessagesIdentity;
GO
CREATE TRIGGER trgtblsysTrackerMessagesIdentity

    DECLARE @intTrackerMessageId INT
    DECLARE @intRowCount INT

    SET @intRowCount = (SELECT COUNT(*) FROM INSERTED)

    SET @intTrackerMessageId = (SELECT intIdentityLast FROM tblsysIdentities WHERE intTableId=1)
    UPDATE tblsysIdentities SET intIdentityLast = @intTrackerMessageId + @intRowCount WHERE intTableId=1

    INSERT INTO tblsysTrackerMessages( 
    [intTrackerMessageId],

From perlfaq5: How can I read in an entire file all at once?:

You can use the File::Slurp module to do it in one step.

use File::Slurp;

$all_of_it = read_file($filename); # entire file in scalar
@all_lines = read_file($filename); # one line per element

The customary Perl approach for processing all the lines in a file is to do so one line at a time:

open (INPUT, $file)     || die "can't open $file: $!";
while (<INPUT>) {
    chomp;
    # do something with $_
    }
close(INPUT)            || die "can't close $file: $!";

This is tremendously more efficient than reading the entire file into memory as an array of lines and then processing it one element at a time, which is often--if not almost always--the wrong approach. Whenever you see someone do this:

@lines = <INPUT>;

you should think long and hard about why you need everything loaded at once. It's just not a scalable solution. You might also find it more fun to use the standard Tie::File module, or the DB_File module's $DB_RECNO bindings, which allow you to tie an array to a file so that accessing an element the array actually accesses the corresponding line in the file.

You can read the entire filehandle contents into a scalar.

{
local(*INPUT, $/);
open (INPUT, $file)     || die "can't open $file: $!";
$var = <INPUT>;
}

That temporarily undefs your record separator, and will automatically close the file at block exit. If the file is already open, just use this:

$var = do { local $/; <INPUT> };

For ordinary files you can also use the read function.

read( INPUT, $var, -s INPUT );

The third argument tests the byte size of the data on the INPUT filehandle and reads that many bytes into the buffer $var.

The following worked for me:

Short answer

Run the following via command line (cmd):

TlbImp.exe cvextern.dll        //where cvextern.dll is your dll you want to fix.

And a valid dll will be created for you.

Longer answer

• Open cmd

• Find TlbImp.exe. Probably located in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin. If you can't find it go to your root folder (C:\ or D:) and run:

  dir tlbimp.exe /s              //this will locate the file.
  

• Run tlbimp.exe and put your dll behind it. Example: If your dll is cvextern.dll. You can run:

  TlbImp.exe cvextern.dll
  

• A new dll has been created in the same folder of tlbimp.exe. You can use that as reference in your project.

A quick true/false test of whether it will cast to [int]

[bool]($var -as [int] -is [int])

I assume that you have a similar view regarding the zoom functionality as I have in this picture:

Now if you mark one of the Zoom In/Zoom Out lines and choose Add Keyboard Shortcut:

You will find that this particular shortcut Numpad + is already occupied so there is a conflict:

So you'll just have assign this Zoom In/Zoom Out to some other keyboard shortcut:

It would help you... assume you have a form with "formname" form and a text box with "txt" name. then you can use following code to allow only aphanumeric values

var checkString = document.formname.txt.value;
if (checkString != "") {
    if ( /[^A-Za-z\d]/.test(checkString)) {
        alert("Please enter only letter and numeric characters");
        document.formname.txt.focus();
        return (false);
    }
}

Why not use a generator instead?

private IEnumerable<string> ReadLogLines(string logPath) {
    using(StreamReader reader = File.OpenText(logPath)) {
        string line = "";
        while((line = reader.ReadLine()) != null) {
            yield return line;
        }
    }
}

Then you can use it like you would use the list:

var logFile = ReadLogLines(LOG_PATH);
foreach(var s in logFile) {
    // Do whatever you need
}

Of course, if you need to have a List<string>, then you will need to keep the entire file contents in memory. There's really no way around that.

Try:

set sw=2

set ts=2

set smartindent

in my case, this error is raised due to sequence was not created..

CREATE SEQUENCE  J.SOME_SEQ  MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER  NOCYCLE ;

I'm not sure if this will work for your actual use, but it works in your test case - updated at http://jsfiddle.net/sTD8y/27/ .

I just made it so that the built-in revert is only used if the item has not been dropped before. If it has been dropped, the revert is done manually. You could adjust this to animate to some calculated offset by checking the actual CSS properties, but I'll let you play with that because a lot of it depends on the CSS of the draggable and it's surrounding DOM structure.

$(function() {
    $("#draggable").draggable({
        revert:  function(dropped) {
             var $draggable = $(this),
                 hasBeenDroppedBefore = $draggable.data('hasBeenDropped'),
                 wasJustDropped = dropped && dropped[0].id == "droppable";
             if(wasJustDropped) {
                 // don't revert, it's in the droppable
                 return false;
             } else {
                 if (hasBeenDroppedBefore) {
                     // don't rely on the built in revert, do it yourself
                     $draggable.animate({ top: 0, left: 0 }, 'slow');
                     return false;
                 } else {
                     // just let the built in revert work, although really, you could animate to 0,0 here as well
                     return true;
                 }
             }
        }
    });

    $("#droppable").droppable({
        activeClass: 'ui-state-hover',
        hoverClass: 'ui-state-active',
        drop: function(event, ui) {
            $(this).addClass('ui-state-highlight').find('p').html('Dropped!');
            $(ui.draggable).data('hasBeenDropped', true);
        }
    });
});

In Node.js versions prior to 0.12.x:

path.basename(filename, path.extname(filename))

Of course this also works in 0.12.x and later.

lepe - That works great for me thanks! I put your code in a plugin file, then used it in conjunction with an each statement so you can have multiple pre tags and multiple "Select all" links on one page and it picks out the correct pre to highlight:

<script type="text/javascript" src="../js/jquery.selecttext.js"></script>
<script type="text/javascript">
  $(document).ready(function() { 
        $(".selectText").each(function(indx) {
                $(this).click(function() {                 
                    $('pre').eq(indx).selText().addClass("selected");
                        return false;               
                    });
        });
  });

StringListName = ObjectListName.stream().map( m -> m.toString() ).collect( Collectors.toList() );

For anyone in the future looking for an answer, I would like to give a much clearer answer to the question.

# for making a tuple
my_tuple = (89, 32)
my_tuple_with_more_values = (1, 2, 3, 4, 5, 6)

# to concatenate tuples
another_tuple = my_tuple + my_tuple_with_more_values
print(another_tuple)
# (89, 32, 1, 2, 3, 4, 5, 6)

# getting a value from a tuple is similar to a list
first_val = my_tuple[0]
second_val = my_tuple[1]

# if you have a function called my_tuple_fun that returns a tuple,
# you might want to do this
my_tuple_fun()[0]
my_tuple_fun()[1]

# or this
v1, v2 = my_tuple_fun()

Hope this clears things up further for those that need it.

Another way:

>>> [i for i in range(len(a)) if a[i] > 2]
[2, 5]

In general, remember that while find is a ready-cooked function, list comprehensions are a general, and thus very powerful solution. Nothing prevents you from writing a find function in Python and use it later as you wish. I.e.:

>>> def find_indices(lst, condition):
...   return [i for i, elem in enumerate(lst) if condition(elem)]
... 
>>> find_indices(a, lambda e: e > 2)
[2, 5]

Note that I'm using lists here to mimic Matlab. It would be more Pythonic to use generators and iterators.

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.
