It appears that your format is incorrect:

If you want to share a locally created repository, or you want to take contributions from someone elses repository - if you want to interact in any way with a new repository, it's generally easiest to add it as a remote. You do that by running git remote add [alias] [url]. That adds [url] under a local remote named [alias].

#example
$ git remote
$ git remote add github [email protected]:schacon/hw.git
$ git remote -v

http://gitref.org/remotes/#remote

git push origin --delete <branch Name>

is easier to remember than

git push origin :branchName

1. git remote rm origin

2. git remote -v It will not display any repository name

3. git remote add origin [email protected]:username/myapp.git

4. git push origin master It will start the process and creating the new branch. You can see your work is pushed to github.

Instead of removing and re-adding, you can do this:

git remote set-url origin git://new.url.here

See this question: How to change the URI (URL) for a remote Git repository?

To remove remote use this:

git remote remove origin

Regarding commits, refs, branches and "et cetera", Magnus answer just works (git remote update).

But unfortunately there is no way to clone / mirror / update the hooks, as I wanted...

I have found this very interesting thread about cloning/mirroring the hooks:

http://kerneltrap.org/mailarchive/git/2007/8/28/256180/thread

I learned:

• The hooks are not considered part of the repository contents.

• There is more data, like the .git/description folder, which does not get cloned, just as the hooks.

• The default hooks that appear in the hooks dir comes from the TEMPLATE_DIR

• There is this interesting template feature on git.

So, I may either ignore this "clone the hooks thing", or go for a rsync strategy, given the purposes of my mirror (backup + source for other clones, only).

Well... I will just forget about hooks cloning, and stick to the git remote update way.

• Sehe has just pointed out that not only "hooks" aren't managed by the clone / update process, but also stashes, rerere, etc... So, for a strict backup, rsync or equivalent would really be the way to go. As this is not really necessary in my case (I can afford not having hooks, stashes, and so on), like I said, I will stick to the remote update.

Thanks! Improved a bit of my own "git-fu"... :-)

The Git URL will be inside the Git configuration file. The value corresponds to the key url.

For Mac and Linux use the commands below:

 cd project_dir
 cat .git/config | grep url | awk '{print $3}'

For Windows open the below file in any text editor and find the value for key url.

project_dir/.git/config

Note: This will work even if you are offline or the remote git server has been taken down.

It's simple and follow the small Steps to proceed:

• Install git on the remote server say some ec2 instance
• Now create a project folder `$mkdir project.git
• $cd project and execute $git init --bare

Let's say this project.git folder is present at your ip with address inside home_folder/workspace/project.git, forex- ec2 - /home/ubuntu/workspace/project.git

Now in your local machine, $cd into the project folder which you want to push to git execute the below commands:

• git init .

• git remote add origin [email protected]:/home/ubuntu/workspace/project.git

• git add .
• git commit -m "Initial commit"

Below is an optional command but found it has been suggested as i was working to setup the same thing

git config --global remote.origin.receivepack "git receive-pack"

• git pull origin master
• git push origin master

This should work fine and will push the local code to the remote git repository.

To check the remote fetch url, cd project_folder/.git and cat config, this will give the remote url being used for pull and push operations.

You can also use an alternative way, after creating the project.git folder on git, clone the project and copy the entire content into that folder. Commit the changes and it should be the same way. While cloning make sure you have access or the key being is the secret key for the remote server being used for deployment.

Troubleshooting :

You may encounter these errors when trying to changing a remote. No such remote '[name]'

This error means that the remote you tried to change doesn't exist:

git remote set-url sofake https://github.com/octocat/Spoon-Knife fatal: No such remote 'sofake'

Check that you've correctly typed the remote name.

Reference : https://help.github.com/articles/changing-a-remote-s-url/

git branch --set-upstream <remote-branch>

sets the default remote branch for the current local branch.

Any future git pull command (with the current local branch checked-out),
will attempt to bring in commits from the <remote-branch> into the current local branch.

One way to avoid having to explicitly type --set-upstream is to use its shorthand flag -u as follows:

git push -u origin local-branch

This sets the upstream association for any future push/pull attempts automatically.
For more details, checkout this detailed explanation about upstream branches and tracking.

To avoid confusion, recent versions of git deprecate this somewhat ambiguous --set-upstream option in favour of a more verbose --set-upstream-to option with identical syntax and behaviour

git branch --set-upstream-to <origin/remote-branch>

Like docs say:

When the command line does not specify where to push with the <repository> argument, branch.*.remote configuration for the current branch is consulted to determine where to push. If the configuration is missing, it defaults to origin.

I met a similar problem when I tried to store my existing repo in my Ubunt One account, I fixed it by the following steps:

Step-1: create remote repo

$ cd ~/Ubuntu\ One/
$ mkdir <project-name>
$ cd <project-name>
$ mkdir .git
$ cd .git
$ git --bare init

Step-2: add the remote

$ git remote add origin /home/<linux-user-name>/Ubuntu\ One/<project-name>/.git

Step-3: push the exising git reop to the remote

$ git push -u origin --all

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

git branch -vv | grep 'BRANCH_NAME'

git branch -vv : This part will show all local branches along with their upstream branch .

grep 'BRANCH_NAME' : It will filter the current branch from the branch list.

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:

git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo 
git checkout --no-track protected_repo/foo

Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.

git push --set-upstream origin foo

Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.

git checkout foo 
git fetch protected_repo
git merge protected_repo/foo

sometimes there's a difference between the local cached version of origin master (origin/master) and the true origin master.

If you run git remote update this will resynch origin master with origin/master

see the accepted answer to this question

Differences between git pull origin master & git pull origin/master

I was having the SAME ERROR AGAIN AND AGAIN.

I added files in local repository and Trying the command

"git push origin master"

Showed Same Error

ALL I WAS MISSING I DID NOT COMMIT .

" git commit -m 'message' "

After Runnig this it worked

Simple just log into your GitHub account and on the far right side in the navigation menu choose Settings, in the Settings Tab choose Default Branch and return back to main page of your repository that did the trick for me.

edit Outdated, just use git push -u origin $BRANCHNAME

Use git publish-branch from William's miscellaneous Git tools.

OK, no Ruby, so - ignoring the safeguards! - take the last three lines of the script and create a bash script, git-publish-branch:

#!/bin/bash
REMOTE=$1 # Rewrite this to make it optional...
BRANCH=$2
# Uncomment the following line to create BRANCH locally first
#git checkout -b ${BRANCH}
git push ${ORIGIN} ${BRANCH}:refs/heads/${BRANCH} &&
git config branch.${BRANCH}.remote ${REMOTE} &&
git config branch.${BRANCH}.merge refs/heads/${BRANCH}

Then run git-publish-branch REMOTENAME BRANCHNAME, where REMOTENAME is usually origin (you may modify the script to take origin as default, etc...)

Two problems:

1 - You never told Git to start tracking any file

You write that you ran

git init
git commit -m "first commit"

and that, at that stage, you got

nothing added to commit but untracked files present (use "git add" to track).

Git is telling you that you never told it to start tracking any files in the first place, and it has nothing to take a snapshot of. Therefore, Git creates no commit. Before attempting to commit, you should tell Git (for instance):

Hey Git, you see that README.md file idly sitting in my working directory, there? Could you put it under version control for me? I'd like it to go in my first commit/snapshot/revision...

For that you need to stage the files of interest, using

git add README.md

before running

git commit -m "some descriptive message"

2 - You haven't set up the remote repository

You then ran

git remote add origin https://github.com/VijayNew/NewExample.git

After that, your local repository should be able to communicate with the remote repository that resides at the specified URL (https://github.com/VijayNew/NewExample.git)... provided that remote repo actually exists! However, it seems that you never created that remote repo on GitHub in the first place: at the time of writing this answer, if I try to visit the correponding URL, I get

Before attempting to push to that remote repository, you need to make sure that the latter actually exists. So go to GitHub and create the remote repo in question. Then and only then will you be able to successfully push with

git push -u origin master

One clarification (and a point that confused me):

"remotes/origin/HEAD is the default branch" is not really correct.

remotes/origin/master was the default branch in the remote repository (last time you checked). HEAD is not a branch, it just points to a branch.

Think of HEAD as your working area. When you think of it this way then 'git checkout branchname' makes sense with respect to changing your working area files to be that of a particular branch. You "checkout" branch files into your working area. HEAD for all practical purposes is what is visible to you in your working area.

my case was a little different - unintentionally I have changed owner of git repository (project.git directory in my case), changing owner back to the git user helped

Git v2.0 Release Notes

Backward compatibility notes

When git push [$there] does not say what to push, we have used the traditional "matching" semantics so far (all your branches were sent to the remote as long as there already are branches of the same name over there). In Git 2.0, the default is now the "simple" semantics, which pushes:

• only the current branch to the branch with the same name, and only when the current branch is set to integrate with that remote branch, if you are pushing to the same remote as you fetch from; or

• only the current branch to the branch with the same name, if you are pushing to a remote that is not where you usually fetch from.

You can use the configuration variable "push.default" to change this. If you are an old-timer who wants to keep using the "matching" semantics, you can set the variable to "matching", for example. Read the documentation for other possibilities.

When git add -u and git add -A are run inside a subdirectory without specifying which paths to add on the command line, they operate on the entire tree for consistency with git commit -a and other commands (these commands used to operate only on the current subdirectory). Say git add -u . or git add -A . if you want to limit the operation to the current directory.

git add <path> is the same as git add -A <path> now, so that git add dir/ will notice paths you removed from the directory and record the removal. In older versions of Git, git add <path> used to ignore removals. You can say git add --ignore-removal <path> to add only added or modified paths in <path>, if you really want to.

you should use :

ln -s /home/jake/doc/test/2000/something xxx

You can achieve this pretty easily with the help of NSPredicate, like so:

NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSFileManager *fm = [NSFileManager defaultManager];
NSArray *dirContents = [fm contentsOfDirectoryAtPath:bundleRoot error:nil];
NSPredicate *fltr = [NSPredicate predicateWithFormat:@"self ENDSWITH '.jpg'"];
NSArray *onlyJPGs = [dirContents filteredArrayUsingPredicate:fltr];

If you need to do it with NSURL instead it looks like this:

NSURL *bundleRoot = [[NSBundle mainBundle] bundleURL];
NSArray * dirContents = 
      [fm contentsOfDirectoryAtURL:bundleRoot
        includingPropertiesForKeys:@[] 
                           options:NSDirectoryEnumerationSkipsHiddenFiles
                             error:nil];
NSPredicate * fltr = [NSPredicate predicateWithFormat:@"pathExtension='jpg'"];
NSArray * onlyJPGs = [dirContents filteredArrayUsingPredicate:fltr];

As far as I can tell, this is currently not possible - a cast is always needed.

To make it possible, the .d.ts of react would need to be modified so that the signature of the onChange of a SELECT element used a new SelectFormEvent. The new event type would expose target, which exposes value. Then the code could be typesafe.

Otherwise there will always be the need for a cast to any.

I could encapsulate all that in a MYSELECT tag.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

fastest way is

Settings -> Developer Options -> Android Debugging

turn off and then on again (tested on CyanogenMod 11)

bool hasErrors =  ViewData.ModelState.Values.Any(x => x.Errors.Count > 1);

or iterate with

    foreach (ModelState state in ViewData.ModelState.Values.Where(x => x.Errors.Count > 0))
    {

    }

window.open(document.getElementById('redirect').href);

Since Django 1.1, you can also use the simpler redirect shortcut:

from django.shortcuts import redirect

def myview(request):
    return redirect('/path')

It also takes an optional permanent=True keyword argument.

An anonymous class usually implements an interface:

new Runnable() { // implements Runnable!
   public void run() {}
}

JFrame.addWindowListener( new WindowAdapter() { // extends  class
} );

If you mean whether you can implement 2 or more interfaces, than I think that's not possible. You can then make a private interface which combines the two. Though I cannot easily imagine why you would want an anonymous class to have that:

 public class MyClass {
   private interface MyInterface extends Runnable, WindowListener { 
   }

   Runnable r = new MyInterface() {
    // your anonymous class which implements 2 interaces
   }

 }

I had the same problem today. Try it!

sudo chown -R  [yourgroup]  /home/[youruser]/.composer/cache/repo/https---packagist.org/


sudo chown -R  [yourgroup]   /home/[youruser]/.composer/cache/files/

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:

FOR /F "tokens=*" %G IN ('dir /b') DO robocopy  "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0

As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.

It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.

Here I propose a way to do this exclusively using the Bootstrap framework built-in functionality.

1. You need to make sure the target div has an ID.
2. Bootstrap has a class "collapse", this will hide your block by default. If you want your div to be collapsible AND be shown by default you need to add "in" class to the collapse. Otherwise the toggle behavior will not work properly.
3. Then, on your hyperlink (also works for buttons), add an href attribute that points to your target div.
4. Finally, add the attribute data-toggle="collapse" to instruct Bootstrap to add an appropriate toggle script to this tag.

Here is a code sample than can be copy-pasted directly on a page that already includes Bootstrap framework (up to version 3.4.1):

<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>
<button href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</button>
<div id="Foo" class="collapse">
    This div (Foo) is hidden by default
</div>
<div id="Bar" class="collapse in">
    This div (Bar) is shown by default and can toggle
</div>

How about this

$.validate.addMethod(cb_selectone,
                   function(value,element){
                           if(element.length>0){
                               for(var i=0;i<element.length;i++){
                                if($(element[i]).val('checked')) return true;
                               }
                           return false;
                           }
                            return false;
                  },
                  'Please select a least one')

Now you ca do

$.validate({rules:{checklist:"cb_selectone"}});

You can even go further a specify the minimum number to select with a third param in the callback function.I have not tested it yet so tell me if it works.

As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.

var mockFileBrowser = new Mock<FileBrowser>();

instead of

var mockFileBrowser = new Mock<IFileBrowser>();

None of them will copy, but the second will refer to a destroyed vector. Named rvalue references almost never exist in regular code. You write it just how you would have written a copy in C++03.

std::vector<int> return_vector()
{
    std::vector<int> tmp {1,2,3,4,5};
    return tmp;
}

std::vector<int> rval_ref = return_vector();

Except now, the vector is moved. The user of a class doesn't deal with it's rvalue references in the vast majority of cases.

If you are using gradle with spring boot and spring JPA then add the below dependency in the build.gradle file

dependencies { compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.1.3.RELEASE'

}

For a more generic answer, convert the error value to hex, then lookup the hex value at Windows Task Scheduler Error and Success Constants

While I agree with Thomas' answer (+1 ;)), I'd like to add the caveat that I'll assume the column that you don't want contains hardly any data. If it contains enormous amounts of text, xml or binary blobs, then take the time to select each column individually. Your performance will suffer otherwise. Cheers!

Same error gets thrown when

A solution without the getInstance method.

Semicolons (like dots, commas and parentheses) tend to cause religious wars. Still, they (or some similar symbol) are useful in any programming language for various reasons.

• Practical: the ability to put several short commands that belong conceptually together on the same line. A program text that looks like a narrow snake has the opposite effect of what is intended by newlines and indentation, which is highlighting structure.

• Conceptual: separation of concerns between pure syntax (in this case, for a sequence of commands) from presentation (e.g. newline), in the old days called "pretty-printing".

Observation: for highlighting structure, indentation could be augmented/replaced by vertical lines in the obvious way, serving as a "visual ruler" to see where an indentation begins and ends. Different colors (e.g. following the color code for resistors) may compensate for crowding.

What it seems like to me is that by calling the keys method you're returning to python a dictionary object when it's looking for a list or a tuple. So try taking all of the keys in the dictionary, putting them into a list and then using the for loop.

downloading the email via the POP3 protocol is the easy part of the task. The protocol is quite simple and the only hard part could be advanced authentication methods if you don't want to send a clear text password over the network (and cannot use the SSL encrypted communication channel). See RFC 1939: Post Office Protocol - Version 3 and RFC 1734: POP3 AUTHentication command for details.

The hard part comes when you have to parse the received email, which means parsing MIME format in most cases. You can write quick&dirty MIME parser in a few hours or days and it will handle 95+% of all incoming messages. Improving the parser so it can parse almost any email means:

• getting email samples sent from the most popular mail clients and improve the parser in order to fix errors and RFC misinterpretations generated by them.
• Making sure that messages violating RFC for message headers and content will not crash your parser and that you will be able to read every readable or guessable value from the mangled email
• correct handling of internationalization issues (e.g. languages written from righ to left, correct encoding for specific language etc)
• UNICODE
• Attachments and hierarchical message item tree as seen in "Mime torture email sample"
• S/MIME (signed and encrypted emails).
• and so on

Debugging a robust MIME parser takes months of work. I know, because I was watching my friend writing one such parser for the component mentioned below and was writing a few unit tests for it too ;-)

Java is typically installed in /usr/java locate the version you have and then do the following:

Assuming you are using bash (if you are just starting off, i recommend bash over other shells) you can simply type in bash to start it.

Edit your ~/.bashrc file and add the paths as follows:

for eg. vi ~/.bashrc

insert following lines:

export JAVA_HOME=/usr/java/<your version of java>
export PATH=${PATH}:${JAVA_HOME}/bin

after you save the changes, exit and restart your bash or just type in bash to start a new shell

Type in export to ensure paths are right.

Type in java -version to ensure Java is accessible.

The problem is that these two queries are each returning more than one row:

select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close')
select isbn from dbo.lending where lended_date between @fdate and @tdate

You have two choices, depending on your desired outcome. You can either replace the above queries with something that's guaranteed to return a single row (for example, by using SELECT TOP 1), OR you can switch your = to IN and return multiple rows, like this:

select * from dbo.books where isbn IN (select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close'))

Coping with different aspect ratios

The different aspect ratios seen above are (from most square; h/w):

1:1     1.0     <- rare for phone; common for watch
4:3     1.3333  <- matches iPad (when portrait)
3:2     1.5000
38:25   1.5200
14:9    1.5556  <- rare
25:16   1.5625
8:5     1.6000  <- aka 16:10
5:3     1.6667
128:75  1.7067
16:9    1.7778  <- matches iPhone 5-7
427:240 1.7792  <- rare
37:18   2.0555  <- Galaxy S8

If you skip the extreme aspect ratios, that are rarely seen at phone size or larger, all the other devices fit a range from 1.3333 to 1.7778, which conveniently matches the current iPhone/iPad ratios (considering all devices in portrait mode). Note that there are quite a few variations within that range, so if you are creating a small number of fixed aspect-ratio layouts, you will need to decide how to handle the odd "in-between" screens.

Minimum "portrait mode" solution is to support 1.3333, which results in unused space at top and bottom, on all the resolutions with larger aspect ratio.
Most likely, you would instead design it to stretch over the 1.333 to 1.778 range. But sometimes part of your design looks too distorted then.

Advanced layout ideas:

For text, you can design for 1.3333, then increase line spacing for 1.666 - though that will look quite sparse. For graphics, design for an intermediate ratio, so that on some screens it is slightly squashed, on others it is slightly stretched. geometric mean of Sqrt(1333 x 1667) ~= 1491. So you design for 1491 x 1000, which will be stretched/squashed by +-12% when assigned to the extreme cases.

Next refinement is to design layout as a stack of different-height "bands" that each fill the width of the screen. Then determine where you can most pleasingly "stretch-or-squash" a band's height, to adjust for different ratios.

For example, consider imaginary phones with 1333 x 1000 pixels and 1666 x 1000 pixels. Suppose you have two "bands", and your main "band" is square, so it is 1000 x 1000. Second band is 333 x 1000 on one screen, 666 x 1000 on the other - quite a range to design for.
You might decide your main band looks okay altered 10% up-or-down, and squash it 900 x 1000 on the 1333 x 1000 screen, leaving 433 x 1000. Then stretch it to 1100 x 1000 on 1666 x 1000 screen, leaving 566 x 1000. So your second band now needs to adjust over only 433 to 566, which has geometric mean of Sqrt(433 x 566) ~= 495. So you design for 495 x 1000, which will be stretched/squashed by +-14% when assigned to the extreme cases.

4 years after the question got posted, but maybe it will help others who run into this problem. The answer has been posted elsewhere on StackExchange as well, but I lost the link and it's hard to find.

ANSWER: In jQueryTOOLS, the jQuery 'core' is also embedded if you use the default download.

When you load jQuery and jQuery tools, jQuery core gets defined twice and will 'unset' any plugins. 'Draggable' (from jQuery-UI) is such a plug-in.

The solution is to use jQuery tools WITHOUT the jQuery 'core' files and everything will work fine.

This work for me

I set style's font before and make rowheader normally then i set in loop for the style with font bolded on each cell of rowhead. Et voilà first row is bolded.

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0); 
HSSFCellStyle style = wb.createCellStyle();
HSSFFont font = wb.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short)10);
font.setBold(true);
style.setFont(font);
rowhead.createCell(0).setCellValue("ID");
rowhead.createCell(1).setCellValue("First");
rowhead.createCell(2).setCellValue("Second");
rowhead.createCell(3).setCellValue("Third");
for(int j = 0; j<=3; j++)
rowhead.getCell(j).setCellStyle(style);

sed '1h;1!H;$!d
     x;s/\n/ /g' YourFile

This does not work for huge files (buffer limit), but it is very efficient if there is enough memory to hold the file. (Correction H-> 1h;1!H after the good remark of @hilojack )

Another version that change new line while reading (more cpu, less memory)

 sed ':loop
 $! N
 s/\n/ /
 t loop' YourFile

This is what I did and it works so far in a MVC 5 application.

Controller's return type is ContentResult.

public ContentResult DoSomething()
{
    if(somethingIsTrue)
    {
        Response.StatusCode = 500 //Anything other than 2XX HTTP status codes should work
        Response.Write("My Message");
        return new ContentResult();
    }

    //Do something in here//
    string json = "whatever json goes here";

    return new ContentResult{Content = json, ContentType = "application/json"};
}

And on client side this is what ajax function looks like

$.ajax({
    type: "POST",
    url: URL,
    data: DATA,
    dataType: "json",
    success: function (json) {
        //Do something with the returned json object.
    },
    error: function (xhr, status, errorThrown) {
        //Here the status code can be retrieved like;
        xhr.status;

        //The message added to Response object in Controller can be retrieved as following.
        xhr.responseText;
    }
});

You can also have a global user git .gitignore file that will apply automatically to all your repos. This is useful for IDE and editor files (e.g. swp and *~ files for Vim). Change directory locations to suit your OS.

1. Add to your ~/.gitconfig file:

   [core]
   excludesfile = /home/username/.gitignore
   

2. Create a ~/.gitignore file with file patterns to be ignored.

3. Save your dot files in another repo so you have a backup (optional).

Any time you copy, init or clone a repo, your global gitignore file will be used as well.

A combobox is unfortunately something that was left out of the HTML specifications.

The only way to manage it, rather unfortunately, is to roll your own or use a pre-built one. This one looks quite simple. I use this one for an open-source app although unfortunately you have to pay for commercial usage.

For your purpose, there is a default event when the row header is double-clicked. Check the following code,

 private void dgvCustom_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
 {
      //Your code goes here
 }

You can also clear the watch inside the callback if you want to clear it right after something happens. That way your $watch will stay active until used.

Like so...

For Apache, you can use mod_ssl to force SSL with the SSLRequireSSL Directive:

This directive forbids access unless HTTP over SSL (i.e. HTTPS) is enabled for the current connection. This is very handy inside the SSL-enabled virtual host or directories for defending against configuration errors that expose stuff that should be protected. When this directive is present all requests are denied which are not using SSL.

This will not do a redirect to https though. To redirect, try the following with mod_rewrite in your .htaccess file

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

or any of the various approaches given at

• http://www.askapache.com/htaccess/http-https-rewriterule-redirect.html

You can also solve this from within PHP in case your provider has disabled .htaccess (which is unlikely since you asked for it, but anyway)

if (!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] !== 'on') {
    if(!headers_sent()) {
        header("Status: 301 Moved Permanently");
        header(sprintf(
            'Location: https://%s%s',
            $_SERVER['HTTP_HOST'],
            $_SERVER['REQUEST_URI']
        ));
        exit();
    }
}

I found these two links very helpful while I was trying to learn socket.io:

• http://fzysqr.com/2011/02/28/nodechat-js-using-node-js-backbone-js-socket-io-and-redis-to-make-a-real-time-chat-app/

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

I suggest using RegExp .test() function to check for a pattern match, and the only thing you need to change is remove the start/end of line anchors (and the * quantifier is also redundant) in the regex:

var format = /[ `!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;_x000D_
//            ^                                       ^   _x000D_
document.write(format.test("My@string-with(some%text)") + "<br/>");_x000D_
document.write(format.test("My string with spaces") + "<br/>");_x000D_
document.write(format.test("MyStringContainingNoSpecialChars"));

The anchors (like ^ start of string/line, $ end od string/line and \b word boundaries) can restrict matches at specific places in a string. When using ^ the regex engine checks if the next subpattern appears right at the start of the string (or line if /m modifier is declared in the regex). Same case with $: the preceding subpattern should match right at the end of the string.

In your case, you want to check the existence of the special character from the set anywhere in the string. Even if it is only one, you want to return false. Thus, you should remove the anchors, and the quantifier *. The * quantifier would match even an empty string, thus we must remove it in order to actually check for the presence of at least 1 special character (actually, without any quantifiers we check for exactly one occurrence, same as if we were using {1} limiting quantifier).

More specific solutions

What characters are "special" for you?

• All chars other than ASCII chars: /[^\x00-\x7F]/ (demo)
• All chars other than printable ASCII chars: /[^ -~]/ (demo)
• Any printable ASCII chars other than space, letters and digits: /[!-\/:-@[-`{-~]/ (demo)
• Any Unicode punctuation proper chars, the \p{P} Unicode property class:
  • ECMAScript 2018: /\p{P}/u

Some additions to a given set of answers:

First of all if you going to use Redis hash efficiently you must know a keys count max number and values max size - otherwise if they break out hash-max-ziplist-value or hash-max-ziplist-entries Redis will convert it to practically usual key/value pairs under a hood. ( see hash-max-ziplist-value, hash-max-ziplist-entries ) And breaking under a hood from a hash options IS REALLY BAD, because each usual key/value pair inside Redis use +90 bytes per pair.

It means that if you start with option two and accidentally break out of max-hash-ziplist-value you will get +90 bytes per EACH ATTRIBUTE you have inside user model! ( actually not the +90 but +70 see console output below )

 # you need me-redis and awesome-print gems to run exact code
 redis = Redis.include(MeRedis).configure( hash_max_ziplist_value: 64, hash_max_ziplist_entries: 512 ).new 
  => #<Redis client v4.0.1 for redis://127.0.0.1:6379/0> 
 > redis.flushdb
  => "OK" 
 > ap redis.info(:memory)
    {
                "used_memory" => "529512",
          **"used_memory_human" => "517.10K"**,
            ....
    }
  => nil 
 # me_set( 't:i' ... ) same as hset( 't:i/512', i % 512 ... )    
 # txt is some english fictionary book around 56K length, 
 # so we just take some random 63-symbols string from it

  {
               "used_memory" => "1251944",
         **"used_memory_human" => "1.19M"**, # ~ 72b per key/value
            .....
  }
  > redis.flushdb
  => "OK" 
  # setting **only one value** +1 byte per hash of 512 values equal to set them all +1 byte 
  > redis.pipelined{ 10000.times{ |i| redis.me_set( "t:#{i}", txt[rand(50000), i % 512 == 0 ? 65 : 63] ) } }; :done 
  > ap redis.info(:memory)
   {
               "used_memory" => "1876064",
         "used_memory_human" => "1.79M",   # ~ 134 bytes per pair  
          ....
   }
    redis.pipelined{ 10000.times{ |i| redis.set( "t:#{i}", txt[rand(50000), 65] ) } };
    ap redis.info(:memory)
    {
             "used_memory" => "2262312",
          "used_memory_human" => "2.16M", #~155 byte per pair i.e. +90 bytes    
           ....
    }

For TheHippo answer, comments on Option one are misleading:

hgetall/hmset/hmget to the rescue if you need all fields or multiple get/set operation.

For BMiner answer.

Third option is actually really fun, for dataset with max(id) < has-max-ziplist-value this solution has O(N) complexity, because, surprise, Reddis store small hashes as array-like container of length/key/value objects!

But many times hashes contain just a few fields. When hashes are small we can instead just encode them in an O(N) data structure, like a linear array with length-prefixed key value pairs. Since we do this only when N is small, the amortized time for HGET and HSET commands is still O(1): the hash will be converted into a real hash table as soon as the number of elements it contains will grow too much

But you should not worry, you'll break hash-max-ziplist-entries very fast and there you go you are now actually at solution number 1.

Second option will most likely go to the fourth solution under a hood because as question states:

Keep in mind that if I use a hash, the value length isn't predictable. They're not all short such as the bio example above.

And as you already said: the fourth solution is the most expensive +70 byte per each attribute for sure.

My suggestion how to optimize such dataset:

You've got two options:

1. If you cannot guarantee max size of some user attributes than you go for first solution and if memory matter is crucial than compress user json before store in redis.

2. If you can force max size of all attributes. Than you can set hash-max-ziplist-entries/value and use hashes either as one hash per user representation OR as hash memory optimization from this topic of a Redis guide: https://redis.io/topics/memory-optimization and store user as json string. Either way you may also compress long user attributes.

Depending on how big your arrays are you might consider an efficient algorithm O(n log n)

def equal_a(a1, a2)
  a1sorted = a1.sort
  a2sorted = a2.sort
  return false if a1.length != a2.length
  0.upto(a1.length - 1) do 
    |i| return false if a1sorted[i] != a2sorted[i]
  end
end

Sorting costs O(n log n) and checking each pair costs O(n) thus this algorithm is O(n log n). The other algorithms cannot be faster (asymptotically) using unsorted arrays.

In my case there was problem in URL. I've use https://example.com - but they ensure 'www.' - so when i switched to https://www.example.com everything was ok. The proper header was sent 'Host: www.example.com'.

You can try make a request in firefox brwoser, persist it and copy as cURL - that how I've found it.

I often use CakePHP when Rails isn't possible. To debug errors I usually find the error.log in the tmp folder and tail it in the terminal with the command...

tail -f app/tmp/logs/error.log

It give's you running dialog from cake of what is going on, which is pretty handy, if you want to output something to it mid code you can use.

$this->log('xxxx');

This can usually give you a good idea of what is going on/wrong.

If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.

I found an example for Linux here:

#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:

import alsaaudio, time, audioop

# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)

# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)

while True:
    # Read data from device
    l,data = inp.read()
    if l:
        # Return the maximum of the absolute value of all samples in a fragment.
        print audioop.max(data, 2)
    time.sleep(.001)

Printf is actually pretty good to use if size matters. Meaning if you are running a program where memory is an issue, then printf is actually a very good and under rater solution. Cout essentially shifts bits over to make room for the string, while printf just takes in some sort of parameters and prints it to the screen. If you were to compile a simple hello world program, printf would be able to compile it in less than 60, 000 bits as opposed to cout, it would take over 1 million bits to compile.

For your situation, id suggest using cout simply because it is much more convenient to use. Although, I would argue that printf is something good to know.

As others have pointed out, you should use zipfile. The documentation tells you what functions are available, but doesn't really explain how you can use them to zip an entire directory. I think it's easiest to explain with some example code:

#!/usr/bin/env python
import os
import zipfile

def zipdir(path, ziph):
    # ziph is zipfile handle
    for root, dirs, files in os.walk(path):
        for file in files:
            ziph.write(os.path.join(root, file), os.path.relpath(os.path.join(root, file), os.path.join(path, '..')))
  
if __name__ == '__main__':
    zipf = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)
    zipdir('tmp/', zipf)
    zipf.close()
 

Adapted from: http://www.devshed.com/c/a/Python/Python-UnZipped/

The problem lies in https.conf file!

# Virtual hosts
# Include conf/extra/httpd-vhosts.conf

The error occurs when hash(#) is removed or messed around with. These two lines should appear as shown above.

Try sys.path[0].

To quote from the Python docs:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

you could use things like display: inline-block but I think you would need to set up another div to move it over, if there is nothing going to the left of the button you could use margins to move it into place.

Alternatively but not a good solution, you could position tags; put the encompassing div as position: relative and then the div of the button as position: absolute; right: 0, but like I said this is probably not the best solution

HTML

<div class="parent">
  <div>Left Div</div>
  <div class="right">Right Div</div>
</div>

CSS

.parent {
  position: relative;
}
.right {
    position: absolute;
    right: 0;
}

I forgot to tell a bug when i use I use req.session.email = req.param('email'), the server error says cannot sett property email of undefined.

The reason of this error is a wrong order of app.use. You must configure express in this order:

app.use(express.cookieParser());
app.use(express.session({ secret: sessionVal }));
app.use(app.route);

Your for loop looks good.

A possible while loop to accomplish the same thing:

int sum = 0;
int i = 1;
while (i <= 100) {
    sum += i;
    i++;
}
System.out.println("The sum is " + sum);

A possible do while loop to accomplish the same thing:

int sum = 0;
int i = 1;
do {
    sum += i;
    i++;
} while (i <= 100);
System.out.println("The sum is " + sum);

The difference between the while and the do while is that, with the do while, at least one iteration is sure to occur.

I think it will work

for (int i = 1; i <= broj_ds; i++ ) 
  { 

     QuantityInIssueUnit_value = dr_art_line_2[i]["Column"];
     QuantityInIssueUnit_uom  = dr_art_line_2[i]["Column"];

  }

have you explored the possibility of using jQuery? It has a very reach selector model (similar in syntax to CSS) and even if your elements don't have IDs, you should be able to select them using parent --> child --> grandchild relationship. Once you have them selected, there's a very simple method call (I forget the exact name) that allows you to apply CSS style to the element(s).

It should be simple to use and as a bonus, you'll most likely be very cross-platform compatible.

for Material design, I just changed the floating action button color like this, Add the below two lines in your Floating action button xml. And done,

 android:backgroundTint="@color/colorPrimaryDark"
 app:borderWidth="0dp"

In Ruby IO module documentation, I suppose.

Mode |  Meaning
-----+--------------------------------------------------------
"r"  |  Read-only, starts at beginning of file  (default mode).
-----+--------------------------------------------------------
"r+" |  Read-write, starts at beginning of file.
-----+--------------------------------------------------------
"w"  |  Write-only, truncates existing file
     |  to zero length or creates a new file for writing.
-----+--------------------------------------------------------
"w+" |  Read-write, truncates existing file to zero length
     |  or creates a new file for reading and writing.
-----+--------------------------------------------------------
"a"  |  Write-only, starts at end of file if file exists,
     |  otherwise creates a new file for writing.
-----+--------------------------------------------------------
"a+" |  Read-write, starts at end of file if file exists,
     |  otherwise creates a new file for reading and

-----+--------------------------------------------------------
"b"  |  Binary file mode (may appear with

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

Have you tried this:

PyGame Drawing Basics

Taken from the site:

pygame.draw.rect(screen, color, (x,y,width,height), thickness) draws a rectangle (x,y,width,height) is a Python tuple x,y are the coordinates of the upper left hand corner width, height are the width and height of the rectangle thickness is the thickness of the line. If it is zero, the rectangle is filled

If there is a space in the beginning of the tns name define in file tnsnames.ora, then some of the the connectors like odbc may give this error. Remove space character in the beginning.

its in the com component, named: "Microsoft Office 14 Object Library"

This is the simplest solution to limit the number of digits after decimal point to two:

myeditText2 = (EditText) findViewById(R.id.editText2);  
myeditText2.setInputType(3);

Dictionary<string, Dictionary<string, string>> like = new Dictionary<string, Dictionary<string, string>>();
Dictionary<string, string> first = like.Values.First();

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

In getUserById you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user. Otherwise Hibernate.initialize(user); is actually Hibernate.initialize(null);

Here's the new getUserById (I haven't tested this ;)):

public User getUserById(Long user_id) {
    Session session = null;
    Object user = null;
    try {
        session = HibernateUtil.getSessionFactory().openSession();
        user = (User)session.load(User.class, user_id);
        Hibernate.initialize(user);
    } catch (Exception e) {
       e.printStackTrace();
    } finally {
        if (session != null && session.isOpen()) {
            session.close();
        }
    }
    return user;
}

As per my personal experience Adobe edge is the best tool for HTML5. It's still in preview mode but you will download it free from Adobe site.

#include <stdio.h>

int main() {

  printf("gcc version: %d.%d.%d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
  return 0;
}

From other post:

    find /c "string" file >NUL
    if %errorlevel% equ 1 goto notfound
        echo found
    goto done
    :notfound
        echo notfound
    goto done
    :done

Use the /i switch when you want case insensitive checking:

    find /i /c "string" file >NUL

Or something like: if not found write to file.

    find /c "%%P" file.txt  || ( echo %%P >> newfile.txt )

Or something like: if found write to file.

    find /c "%%P" file.txt  && ( echo %%P >> newfile.txt )

Or something like:

    find /c "%%P" file.txt  && ( echo found ) || ( echo not found )

Just use awk, it's much simpler than grep in letting you clearly express compound conditions.

If you want to skip lines that contains both loom and gloom:

awk '/loom/ && !/gloom/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

or if you want to print them:

awk '/(^|[^g])loom/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

and if the reality is you just want lines where loom appears as a word by itself:

awk '/\<loom\>/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

Visual studio 2019 version:

The drop down menu was moved to:

• Right click on project (not solution)
• Properties (or Alt + Enter)
• From the left menu select Configuration Properties
• General
• In the middle there is an option called "C++ Language Standard"
• Next to it is the drop down menu
• Here you can select Default, ISO C++ 14, 17 or latest

You could try the FLOOR function like this:

SELECT FLOOR(columnName), moreColumns, etc 
FROM myTable 
WHERE ... 

You could also try the FORMAT function, provided you know the decimal places can be omitted:

SELECT FORMAT(columnName,0), moreColumns, etc 
FROM myTable 
WHERE ... 

You could combine the two functions

SELECT FORMAT(FLOOR(columnName),0), moreColumns, etc 
FROM myTable 
WHERE ... 

If you want to concatenate the fields using / as a separator, you can use concat_ws:

select concat_ws('/', col1, col2, col3) from mytable

You cannot escape listing the columns in the query though. The *-syntax works only in "select * from". You can list the columns and construct the query dynamically though.

You miss parenthesis:

var value: string = dataObjects[i].getValue(); 
var id: number = dataObjects[i].getId();

Got into this issue for [cqlsh 5.0.1 | Cassandra 3.11.4 | CQL spec 3.4.4 | Native protocol v4] had to set start_native_transport: true in cassandra.yaml file.

For verification,

• try opening tailf /var/log/cassandra/system.log file in one-tab
• update cassandra.yaml
• restart cassandra sudo service cassandra restart

In logfile is shows.

This usually happens when debugging using the emulator, which is known to be slow anyway.

None of the answers were specific to my problem, so here's how I did it.

This is for Visual Studio 2015 and I had already made a repository on Github.com

If you already have your repository URL copy it and then in visual studio:

• Go to Team Explorer
• Click the "Sync" button
• It should have 3 options listed with "get started" links.
• I chose the "get started" link against "publish to remote repository", which it the bottom one
• A yellow box will appear asking for the URL. Just paste the URL there and click publish.

No jQuery Needed

if (str.match(/[a-z]/i)) {
    // alphabet letters found
}

You would use data validation for this. Click in the cell you want to have a multiple drop down > DATA > Validation > Criteria (List from a Range) - here you select form a list of items you want in the drop down. And .. you are good. I have included an example to reference.

myDate.ToString("yyyy-MM-dd HH:mm:ss")

the capital HH is for 24 hours format as you specified

To open IIS Manager, click Start, type inetmgr in the Search Programs and Files box, and then press ENTER.

if the IIS Manager doesn't open that means you need to install it.

You can use CSS's pseudo-class to do that. A pseudo-class is used to define a special state of an element.

there is a ::focus pseudo-class that is used to select the element that has focus. So you can hook it in your CSS like this

Using class

.my-input::focus {
  outline-color: green;
}

Using Id

#my-input::focus {
  outline-color: red;
}

Directly selecting element

input::focus {
  outline-color: blue;
}

Using attribute selector

input[type="text"]::focus {
  outline-color: orange;
}

The accepted answer worked for me using a CollapsingToolbarLayout. It's important to note though, that setSytstemUiVisibility() overrides any previous calls to that function. So if you're using that function somewhere else for the same view, you need to include the View.SYSTEM_UI_FLAG_LAYOUT_STABLE and View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flags, or they will be overridden with the new call.

This was the case for me, and once I added the two flags to the other place I was making a call to setSystemUiVisibility(), the accepted answer worked perfectly.

If Subversion is already installed ,there's no need to reinstall it with the command line client tools.

From here.

Each tab bar item has a title, selected image, unselected image, and a badge value.

Use the Image Tint (selectedImageTintColor) field to specify the bar item’s tint color when that tab is selected. By default, that color is blue.

You may be used to MySQL's syntax: Microsoft SQL @ is the same as the MySQL's ?

It can be done in your code via WMI. I've found a tool from Microsoft that creates code for it.

The WMI Code Creator tool allows you to generate VBScript, C#, and VB .NET code that uses WMI to complete a management task such as querying for management data, executing a method from a WMI class, or receiving event notifications using WMI.

You can check if the Connected property is set to $true and display a friendly message:

    $t = New-Object Net.Sockets.TcpClient "10.45.23.109", 443 

    if($t.Connected)
    {
        "Port 443 is operational"
    }
    else

It's the new feature in C# 6 called Interpolated Strings.

The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.

For more details about this, please take a look at MSDN.

Now, think a little bit more about it. Why this feature is great?

For example, you have class Point:

public class Point
{
    public int X { get; set; }

    public int Y { get; set; }
}

Create 2 instances:

var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };

Now, you want to output it to the screen. The 2 ways that you usually use:

Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");

As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:

Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));

This creates a new problem:

1. You have to maintain the number of arguments and index yourself. If the number of arguments and index are not the same, it will generate a runtime error.

For those reasons, we should use new feature:

Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");

The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

For the full post, please read this blog.

It seems none of the current answers will actually remove 100% of whitespace from the start and end of a string.

As mentioned in other posts, the default TRIM only removes spaces - not tabs, formfeeds etc. A combination of TRIMs specifying other whitespace characters may provide a limited improvement e.g. TRIM(BOTH '\r' FROM TRIM(BOTH '\n' FROM TRIM(BOTH '\f' FROM TRIM(BOTH '\t' FROM TRIM(txt))))). But the problem with this approach is only a single character can be specified for a particular TRIM and those characters are only removed from the start and end. So if the string being trimmed is something like \t \t \t \t (i.e. alternate spaces and tab characters), more TRIMs would be needed - and in the general case this could go on indefinitely.

For a lightweight solution, it should be possible to write a simple User Defined Function (UDF) to do the job by looping through the characters at the start and end of a string. But I'm not going to do that... as I've already written a rather more heavyweight regular expression replacer which can also do the job - and may come in useful for other reasons, as described in this blog post.

Let's go back to the old school of batch programing on windows

net start | find "Service Name"

This will work everywhere...

Create a URI like this one:

https://maps.google.com/?q=[lat],[long]

For example:

https://maps.google.com/?q=-37.866963,144.980615

or, if you are using the javascript API

map.setCenter(new GLatLng(0,0))

This, and other helpful info comes from here:

https://developers.google.com/maps/documentation/javascript/reference/?csw=1#Map

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";_x000D_
var str2 = "DEFG";_x000D_
if(str1.indexOf(str2) != -1){_x000D_
    console.log(str2 + " found");_x000D_
}

I consider the jQuery plugin "jQuery resize event" to be the best solution for this as it takes care of throttling the event so that it works the same across all browsers. It's similar to Andrews answer but better since you can hook the resize event to specific elements/selectors as well as the entire window. It opens up new possibilities to write clean code.

The plugin is available here

There are performance issues if you add a lot of listeners, but for most usage cases it's perfect.

Inline Stored procedure we using as per our need. Example like different Same parameter with different values we have to use in queries..

Create Proc SP1
(
 @ID int,
 @Name varchar(40)
 -- etc parameter list, If you don't have any parameter then no need to pass.
 )

  AS
  BEGIN

  -- Here we have some opereations

 -- If there is any Error Before Executing SP2 then SP will stop executing.

  Exec SP2 @ID,@Name,@SomeID OUTPUT 

 -- ,etc some other parameter also we can use OutPut parameters like 

 -- @SomeID is useful for some other operations for condition checking insertion etc.

 -- If you have any Error in you SP2 then also it will stop executing.

 -- If you want to do any other operation after executing SP2 that we can do here.

END

Some might encounter this error (I got it while implementing PHP-MySQLi-JSON-Google Chart Example):

You called the draw() method with the wrong type of data rather than a DataTable or DataView.

The solution would be: replace jsapi and just use loader.js with:

google.charts.load('current', {packages: ['corechart']}) and 
google.charts.setOnLoadCallback 

-- according to the release notes --> The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.

There is HTML entity &#10003 but it doesn't work in some older browsers.

If you want to build a different configuration without regenerating if using you can also run cmake --build {$PWD} --config <cfg> For multi-configuration tools, choose <cfg> ex. Debug, Release, MinSizeRel, RelWithDebInfo

https://cmake.org/cmake/help/v2.8.11/cmake.html#opt%3a--builddir

$(document).ready(function() {
 $('#content').load('your_url_here');
});

It looks like you are passing an NSString parameter where you should be passing an NSData parameter:

NSError *jsonError;
NSData *objectData = [@"{\"2\":\"3\"}" dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
                                      options:NSJSONReadingMutableContainers 
                                        error:&jsonError];

You can use PowerShell.

Eclipse can't work out what you want to run and since you've not run anything before, it can't try re-running that either.

Instead of clicking the green 'run' button, click the dropdown next to it and chose Run Configurations. On the Android tab, make sure it's set to your project. In the Target tab, set the tick box and options as appropriate to target your device. Then click Run. Keep an eye on your Console tab in Eclipse - that'll let you know what's going on. Once you've got your run configuration set, you can just hit the green 'run' button next time.

Sometimes getting everything to talk to your device can be problematic to begin with. Consider using an AVD (i.e. an emulator) as alternative, at least to begin with if you have problems. You can easily create one from the menu Window -> Android Virtual Device Manager within Eclipse.

To view the progress of your project being installed and started on your device, check the console. It's a panel within Eclipse with the tabs Problems/Javadoc/Declaration/Console/LogCat etc. It may be minimised - check the tray in the bottom right. Or just use Window/Show View/Console from the menu to make it come to the front. There are two consoles, Android and DDMS - there is a dropdown by its icon where you can switch.

Import jquery first before bootstrap:

<script src="js/jquery.min.js"></script>

<script src="js/bootstrap.bundle.js"></script>

I am fairly new to Javascript. But this is what I understood: JSON.parse() returns SyntaxError exceptions when invalid JSON is provided as its first parameter. So. It would be better to catch that exception as such like as follows:

try {
    let sData = `
        {
            "id": "1",
            "name": "UbuntuGod",
        }
    `;
    console.log(JSON.parse(sData));
} catch (objError) {
    if (objError instanceof SyntaxError) {
        console.error(objError.name);
    } else {
        console.error(objError.message);
    }
}

The reason why I made the words "first parameter" bold is that JSON.parse() takes a reviver function as its second parameter.

$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Select-Object Size,FreeSpace

$disk.Size
$disk.FreeSpace

To extract the values only and assign them to a variable:

$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Foreach-Object {$_.Size,$_.FreeSpace}

I think the example given by Rico Mariani was good: it may be appropriate to trigger a GC if there is a significant change in the application's state. For example, in a document editor it may be OK to trigger a GC when a document is closed.

OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!

edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)

Often you will want to have a definition of an interface without having to ship the entire code. For example, if you have a shared library, you would ship a header file with it which defines all the functions and symbols used in the shared library. Without header files, you would need to ship the source.

Within a single project, header files are used, IMHO, for at least two purposes:

• Clarity, that is, by keeping the interfaces separate from the implementation, it is easier to read the code
• Compile time. By using only the interface where possible, instead of the full implementation, the compile time can be reduced because the compiler can simply make a reference to the interface instead of having to parse the actual code (which, idealy, would only need to be done a single time).

This can do the trick,

function createLog($data){ 
    $file = "Your path/incompletejobs.txt";
    $fh = fopen($file, 'a') or die("can't open file");
    fwrite($fh,$data);
    fclose($fh);
}
$qry="INSERT INTO redirects SET ua_string = '$ua_string'"   
$result=mysql_query($qry);
if(!$result){
    createLog(mysql_error());
}

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

change the package of classes, your files are probably in the wrong package, happened to me when I copied the code from a friend, it was the default package and mine was another, hence the netbeans could not compile because of it.

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

In my case I refactored code and put the creation of the Dialog in a separate class. I only handed over the clicked View because a View contains a context object already. This led to the same error message although all ran on the MainThread.

I then switched to handing over the Activity as well and used its context in the dialog creation -> Everything works now.

    fun showDialogToDeletePhoto(baseActivity: BaseActivity, clickedParent: View, deletePhotoClickedListener: DeletePhotoClickedListener) {
        val dialog = AlertDialog.Builder(baseActivity) // <-- here
   .setTitle(baseActivity.getString(R.string.alert_delete_picture_dialog_title))
...
}

I , can't format the code snippet properly, sorry :(

I tried doing something similar, which took me a lot of time before I could figure out the collect() function. So you can have something this way:

collect($items)->sum('amount');

This will give you the sum total of all the items.

In my case, it was unable to find the .eslintrc file so I copied from node_modules/.bin to root.

Here is a clean method I've discovered:

$myArray = [];

array_push($myArray, (object)[
        'key1' => 'someValue',
        'key2' => 'someValue2',
        'key3' => 'someValue3',
]);

return $myArray;

Sometimes it is important to analyze what's going on during the start up of the service. Attaching to the process does not help here, because you are not quick enough to attach the debugger while the service is starting up.

The short answer is, I am using the following 4 lines of code to do this:

#if DEBUG
    base.RequestAdditionalTime(600000); // 600*1000ms = 10 minutes timeout
    Debugger.Launch(); // launch and attach debugger
#endif

These are inserted into the OnStart method of the service as follows:

protected override void OnStart(string[] args)
{
    #if DEBUG
       base.RequestAdditionalTime(600000); // 10 minutes timeout for startup
       Debugger.Launch(); // launch and attach debugger
    #endif
    MyInitOnstart(); // my individual initialization code for the service
    // allow the base class to perform any work it needs to do
    base.OnStart(args);
}

For those who haven't done it before, I have included detailed hints below, because you can easily get stuck. The following hints refer to Windows 7x64 and Visual Studio 2010 Team Edition, but should be valid for other environments, too.

Important: Deploy the service in "manual" mode (using either the InstallUtil utility from the VS command prompt or run a service installer project you have prepared). Open Visual Studio before you start the service and load the solution containing the service's source code - set up additional breakpoints as you require them in Visual Studio - then start the service via the Service Control Panel.

Because of the Debugger.Launch code, this will cause a dialog "An unhandled Microsoft .NET Framework exception occured in Servicename.exe." to appear. Click Yes, debug Servicename.exe as shown in the screenshot:

Afterwards, escpecially in Windows 7 UAC might prompt you to enter admin credentials. Enter them and proceed with Yes:

After that, the well known Visual Studio Just-In-Time Debugger window appears. It asks you if you want to debug using the delected debugger. Before you click Yes, select that you don't want to open a new instance (2nd option) - a new instance would not be helpful here, because the source code wouldn't be displayed. So you select the Visual Studio instance you've opened earlier instead:

After you have clicked Yes, after a while Visual Studio will show the yellow arrow right in the line where the Debugger.Launch statement is and you are able to debug your code (method MyInitOnStart, which contains your initialization).

Pressing F5 continues execution immediately, until the next breakpoint you have prepared is reached.

Hint: To keep the service running, select Debug -> Detach all. This allows you to run a client communicating with the service after it started up correctly and you're finished debugging the startup code. If you press Shift+F5 (stop debugging), this will terminate the service. Instead of doing this, you should use the Service Control Panel to stop it.

Note that

• If you build a Release, then the debug code is automatically removed and the service runs normally.

• I am using Debugger.Launch(), which starts and attaches a debugger. I have tested Debugger.Break() as well, which did not work, because there is no debugger attached on start up of the service yet (causing the "Error 1067: The process terminated unexpectedly.").

• RequestAdditionalTime sets a longer timeout for the startup of the service (it is not delaying the code itself, but will immediately continue with the Debugger.Launch statement). Otherwise the default timeout for starting the service is too short and starting the service fails if you don't call base.Onstart(args) quickly enough from the debugger. Practically, a timeout of 10 minutes avoids that you see the message "the service did not respond..." immediately after the debugger is started.

• Once you get used to it, this method is very easy because it just requires you to add 4 lines to an existing service code, allowing you quickly to gain control and debug.

Simply convert boolean field to integer and do a sum. This will work on postgresql :

Hope that helps!

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

To create global gitignore from scratch:

$ cd ~
$ touch .gitignore_global
$ git config --global core.excludesfile ~/.gitignore_global

1. First line changes directory to C:/Users/User
2. After that you create an empty file with .gitignore_global extension
3. And finally setting global ignore to that file.
4. Then you should open it with some kind of notepad and add the needed ignore rules.

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
        .buildAndExpand(params)
        .toUri();
uri = UriComponentsBuilder
        .fromUri(uri)
        .queryParam("name", "myName")
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

The safe way is to expand the path variables first, and then add the query parameters:

For me this resulted in duplicated encoding, e.g. a space was decoded to %2520 (space -> %20 -> %25).

I solved it by:

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
UriComponentsBuilder uriComponentsBuilder = UriComponentsBuilder.fromUriString(url);
uriComponentsBuilder.uriVariables(params);
Uri uri = uriComponentsBuilder.queryParam("name", "myName");
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

Essentially I am using uriComponentsBuilder.uriVariables(params); to add path parameters. The documentation says:

... In contrast to UriComponents.expand(Map) or buildAndExpand(Map), this method is useful when you need to supply URI variables without building the UriComponents instance just yet, or perhaps pre-expand some shared default values such as host and port. ...

Using regex to parse html is not recommended

regex is used for regularly occurring patterns.html is not regular with it's format(except xhtml).For example html files are valid even if you don't have a closing tag!This could break your code.

Use an html parser like htmlagilitypack

You can use this code to retrieve all href's in anchor tag using HtmlAgilityPack

HtmlDocument doc = new HtmlDocument();
doc.Load(yourStream);

var hrefList = doc.DocumentNode.SelectNodes("//a")
                  .Select(p => p.GetAttributeValue("href", "not found"))
                  .ToList();

hrefList contains all href`s

If you don't want it to look horrible I'd suggest defining a list of colours in an array and then using a random number generator to pick one.

If you want a truly random colour you can just generate 3 random numbers from 0 to 255 and then use the Color(int,int,int) constructor to create a new Color instance.

Random randomGenerator = new Random();
int red = randomGenerator.nextInt(256);
int green = randomGenerator.nextInt(256);
int blue = randomGenerator.nextInt(256);

Color randomColour = new Color(red,green,blue);

Use the exact layout numbers described here and a nice blogpost here.

so:

layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)

if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

gives:

>> 2014-11-12 11:45:26.371 +0000 UTC

I know. Mind boggling. Also caught me first time. Go just doesn't use an abstract syntax for datetime components (YYYY-MM-DD), but these exact numbers (I think the time of the first commit of go Nope, according to this. Does anyone know?).

Abstract factory is an interface for creating related objects but factory method is a method. Abstract factory is implemented by factory method.

JMeter would be one such tool. Can be a bit hard to learn and configure, but it's usually worth it.

You should use

this.router.parent.navigate(['/About']);

As well as specifying the route path, you can also specify your route's name:

{ path:'/About', name: 'About',   ... }

this.router.parent.navigate(['About']);

In my case (I am a noob), I was testing Servlet that make database connection with MySQL and one of the Exception is the one mentioned above.

It made my head swing for some seconds but I came to realize that it was because I have not started my MySQL server in localhost.
After starting the server, the problem was fixed.

So, check whether MySQL server is running properly.

• A extends B:

  A and B are both classes or both interfaces

• A implements B

  A is a class and B is an interface

• The remaining case where A is an interface and B is a class is not legal in Java.

I had this issue, jquery URL was valid, everything looked good and validation still worked. After a hard refresh CTL+F5 the error went away in Chrome.

1. Always try sending headers in the mail function.
2. If you are sending mail through localhost then do the SMTP settings for sending mail.
3. If you are sending mail through a server then check the email sending feature is enabled on your server.

Also, I had this issue using Laravel, but fixed by changing my database schema to allow "null" inputs on a table where I plan to collect the information from separate forms:

public function up()
{

    Schema::create('trip_table', function (Blueprint $table) {
        $table->increments('trip_id')->unsigned();
        $table->time('est_start');
        $table->time('est_end');
        $table->time('act_start')->nullable();
        $table->time('act_end')->nullable();
        $table->date('Trip_Date');
        $table->integer('Starting_Miles')->nullable();
        $table->integer('Ending_Miles')->nullable();
        $table->string('Bus_id')->nullable();
        $table->string('Event');
        $table->string('Desc')->nullable();
        $table->string('Destination');
        $table->string('Departure_location');
        $table->text('Drivers_Comment')->nullable();
        $table->string('Requester')->nullable();
        $table->integer('driver_id')->nullable();
        $table->timestamps();
    });

}

The ->nullable(); Added to the end. This is using Laravel. Hope this helps someone, thanks!

As pointed out by others, Python 3's int does not have a maximum size, but if you just need something that's guaranteed to be higher than any other int value, then you can use the float value for Infinity, which you can get with float("inf").

Check if you don't have a ScrollView wrapping your Webview.

In my case that was the problem. It seems ScrollView gets in the way of the pinch gesture.

To fix it, just take your Webview outside the ScrollView.

A class method receives the class as implicit first argument, just like an instance method receives the instance. It is a method which is bound to the class and not the object of the class.It has access to the state of the class as it takes a class parameter that points to the class and not the object instance. It can modify a class state that would apply across all the instances of the class. For example it can modify a class variable that will be applicable to all the instances.

On the other hand, a static method does not receive an implicit first argument, compared to class methods or instance methods. And can’t access or modify class state. It only belongs to the class because from design point of view that is the correct way. But in terms of functionality is not bound, at runtime, to the class.

as a guideline, use static methods as utilities, use class methods for example as factory . Or maybe to define a singleton. And use instance methods to model the state and behavior of instances.

Hope I was clear !

I just want to write an small enhancement for the answer of amirnissim
The script posted doesn't support IE8, because "event.which" seems to be always empty in IE8.
To solve this problem you just need to additionally check for "event.keyCode":

listener = function (event) {
  if (event.which == 13 || event.keyCode == 13) {
    var suggestion_selected = $(".pac-item.pac-selected").length > 0;
    if(!suggestion_selected){
      var simulated_downarrow = $.Event("keydown", {keyCode:40, which:40})
      orig_listener.apply(input, [simulated_downarrow]);
    }
  }
  orig_listener.apply(input, [event]);
};

I give here 2 ways of coping array, for C and C++ language. memcpy and copy both ar usable on C++ but copy is not usable for C, you have to use memcpy if you are trying to copy array in C.

#include <stdio.h>
#include <iostream>
#include <algorithm> // for using copy (library function)
#include <string.h> // for using memcpy (library function)


int main(){

    int arr[] = {1, 1, 2, 2, 3, 3};
    int brr[100];

    int len = sizeof(arr)/sizeof(*arr); // finding size of arr (array)

    std:: copy(arr, arr+len, brr); // which will work on C++ only (you have to use #include <algorithm>
    memcpy(brr, arr, len*(sizeof(int))); // which will work on both C and C++

    for(int i=0; i<len; i++){ // Printing brr (array).
        std:: cout << brr[i] << " ";
    }

    return 0;
}

When managing the actual files, things can get out of sync pretty easily unless you're really vigilant. So we've launched a (beta) free service called String which allows you to keep track of your language files easily, and collaborate with translators.

You can either import existing language files (in PHP array, PHP Define, ini, po or .strings formats) or create your own sections from scratch and add content directly through the system.

String is totally free so please check it out and tell us what you think.

It's actually built on Codeigniter too! Check out the beta at http://mygengo.com/string

ok, this has been answered, but I thought you might like to see my answer that calls the math.pow() function once. I guess I like keeping things DRY.

function roundIt(num, precision) {
    var rounder = Math.pow(10, precision);
    return (Math.round(num * rounder) / rounder).toFixed(precision)
};

It kind of puts it all together. Replace Math.round() with Math.ceil() to round-up instead of rounding-off, which is what the OP wanted.

For your specific case, the body is for creating a variable, and switching to IEnumerable will force all the operations to be processed on client-side, I propose the following solution.

Obj[] myArray = objects
.Select(o => new
{
    SomeLocalVar = o.someVar, // You can even use any LINQ statement here
    Info = o,
}).Select(o => new Obj()
{
    Var1 = o.SomeLocalVar,
    Var2 = o.Info.var2,
    Var3 = o.SomeLocalVar.SubValue1,
    Var4 = o.SomeLocalVar.SubValue2,
}).ToArray();

Edit: Rename for C# Coding Convention

Fitting a moving average to your data would smooth out the noise, see this this answer for how to do that.

If you'd like to use LOWESS to fit your data (it's similar to a moving average but more sophisticated), you can do that using the statsmodels library:

import numpy as np
import pylab as plt
import statsmodels.api as sm

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2
lowess = sm.nonparametric.lowess(y, x, frac=0.1)

plt.plot(x, y, '+')
plt.plot(lowess[:, 0], lowess[:, 1])
plt.show()

Finally, if you know the functional form of your signal, you could fit a curve to your data, which would probably be the best thing to do.

In the file that has the script, you want to do something like this:

import os
dirname = os.path.dirname(__file__)
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

This will give you the absolute path to the file you're looking for. Note that if you're using setuptools, you should probably use its package resources API instead.

UPDATE: I'm responding to a comment here so I can paste a code sample. :-)

Am I correct in thinking that __file__ is not always available (e.g. when you run the file directly rather than importing it)?

I'm assuming you mean the __main__ script when you mention running the file directly. If so, that doesn't appear to be the case on my system (python 2.5.1 on OS X 10.5.7):

#foo.py
import os
print os.getcwd()
print __file__

#in the interactive interpreter
>>> import foo
/Users/jason
foo.py

#and finally, at the shell:
~ % python foo.py
/Users/jason
foo.py

However, I do know that there are some quirks with __file__ on C extensions. For example, I can do this on my Mac:

>>> import collections #note that collections is a C extension in Python 2.5
>>> collections.__file__
'/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-
dynload/collections.so'

However, this raises an exception on my Windows machine.

Yes, I found MySQL also cannot edit result tables. Usually results tables joining other tables don't have primary keys. I heard other suggested put the result table in another table, but the better solution is to use Dbeaver which can edit result tables.

I changed my deployment target to 7.1 the same as my iphone, and now I can run swift programs on it. It was on 8.0 and showed up as ineligible.

I like to be a bit more specific as to which records I delete so here is my solution:

delete
from jobs c1
where not c1.location = 'Paris'
and  c1.site_id > 64218
and exists 
(  
select * from jobs c2 
where c2.site_id = c1.site_id
and   c2.company = c1.company
and   c2.location = c1.location
and   c2.title = c1.title
and   c2.site_id > 63412
and   c2.site_id < 64219
)

Please check if JIRA status in "In Development". For me , it was not , when i changed jira status to "In Development", it worked for me.

I think this means that module.exports in your ./app/routes module is not assigned to be a function so therefore require('./app/routes') does not resolve to a function so therefore, you cannot call it as a function like this require('./app/routes')(app, passport).

Show us ./app/routes if you want us to comment further on that.

It should look something like this;

module.exports = function(app, passport) {
    // code here
}

You are exporting a function that can then be called like require('./app/routes')(app, passport).

One other reason a similar error could occur is if you have a circular module dependency where module A is trying to require(B) and module B is trying to require(A). When this happens, it will be detected by the require() sub-system and one of them will come back as null and thus trying to call that as a function will not work. The fix in that case is to remove the circular dependency, usually by breaking common code into a third module that both can separately load though the specifics of fixing a circular dependency are unique for each situation.

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

Maybe you mean like this? I like to make an object and use Format-Table:

> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table

Name                                                                        Age Info
----                                                                        --- ----
Joe                                                                          32  something about him

This will put all objects you have in the array in columns according to their properties.

Tip: Using -auto sizes the table better

> $array | Format-Table -Auto

Name Age Info
---- --- ----
Joe   32 something about him

You can also specify which properties you want in the table. Just separate each property name with a comma:

> $array | Format-Table Name, Age -Auto

Name Age
---- ---
Joe   32

The params object is included in $stateParams, but won't be part of the url.

1) In the route configuration:

$stateProvider.state('edit_user', {
    url: '/users/:user_id/edit',
    templateUrl: 'views/editUser.html',
    controller: 'editUserCtrl',
    params: {
        paramOne: { objectProperty: "defaultValueOne" },  //default value
        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

Coming here from first Google hit:

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1.

On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1 the warning will go away.

It's probably because you are building a gem from source and the gemspec shells out to git, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git but addressing that is for another day :)

My answer is a duplicate of: - comment GIT_DISCOVERY_ACROSS_FILESYSTEM problem when working with terminal and MacFusion

you can also introspect all HTTP traffic running over your tunnels using ngrok , then you can expose using ngrok http --host-header=rewrite 4200

In Windows 8.1 x64 bit os, Currently I am using MySQL version :

Server version: 5.7.11-log MySQL Community Server (GPL)

For changing your MySQL port number, Go to installation directory, my installation directory is :

C:\Program Files\MySQL\MySQL Server 5.7

open the my-default.ini Configuration Setting file in any text editor.

search the line in the configuration file.

# port = .....

replace it with :

port=<my_new_port_number>

like my self changed to :

port=15800

To apply the changes don't forget to immediate either restart the MySQL Server or your OS.

Hope this would help many one.

The tick_params method is very useful for stuff like this. This code turns off major and minor ticks and removes the labels from the x-axis.

from matplotlib import pyplot as plt
plt.plot(range(10))
plt.tick_params(
    axis='x',          # changes apply to the x-axis
    which='both',      # both major and minor ticks are affected
    bottom=False,      # ticks along the bottom edge are off
    top=False,         # ticks along the top edge are off
    labelbottom=False) # labels along the bottom edge are off
plt.show()
plt.savefig('plot')
plt.clf()

You need to open the file again using open(), but this time passing 'w' to indicate that you want to write to the file. I would also recommend using with to ensure that the file will be closed when you are finished writing to it.

with open('Failed.txt', 'w') as f:
    for ip in [k for k, v in ips.iteritems() if v >=5]:
        f.write(ip)

Naturally you may want to include newlines or other formatting in your output, but the basics are as above.

The same issue with closing your file applies to the reading code. That should look like this:

ips = {}
with open('today','r') as myFile:
    for line in myFile:
        parts = line.split(' ')
        if parts[1] == 'Failure':
            if parts[0] in ips:
                ips[pars[0]] += 1
            else:
                ips[parts[0]] = 0

You can simply implement the same using the application iResign.

Give path of 1).ipa

2) New provision profile

3) Entitlement file (Optional, add only if you have entitlement)

4) Bundle id

5) Distribution Certificate

You can see output .ipa file saved after re-sign

Simple and powerful tool

I was wondering if it is possible to execute something like this using JDBC.

"SELECT FROM * TABLE;INSERT INTO TABLE;"

Yes it is possible. There are two ways, as far as I know. They are

1. By setting database connection property to allow multiple queries, separated by a semi-colon by default.
2. By calling a stored procedure that returns cursors implicit.

Following examples demonstrate the above two possibilities.

Example 1: ( To allow multiple queries ):

While sending a connection request, you need to append a connection property allowMultiQueries=true to the database url. This is additional connection property to those if already exists some, like autoReConnect=true, etc.. Acceptable values for allowMultiQueries property are true, false, yes, and no. Any other value is rejected at runtime with an SQLException.

String dbUrl = "jdbc:mysql:///test?allowMultiQueries=true";  

Unless such instruction is passed, an SQLException is thrown.

You have to use execute( String sql ) or its other variants to fetch results of the query execution.

boolean hasMoreResultSets = stmt.execute( multiQuerySqlString );

To iterate through and process results you require following steps:

READING_QUERY_RESULTS: // label  
    while ( hasMoreResultSets || stmt.getUpdateCount() != -1 ) {  
        if ( hasMoreResultSets ) {  
            Resultset rs = stmt.getResultSet();
            // handle your rs here
        } // if has rs
        else { // if ddl/dml/...
            int queryResult = stmt.getUpdateCount();  
            if ( queryResult == -1 ) { // no more queries processed  
                break READING_QUERY_RESULTS;  
            } // no more queries processed  
            // handle success, failure, generated keys, etc here
        } // if ddl/dml/...

        // check to continue in the loop  
        hasMoreResultSets = stmt.getMoreResults();  
    } // while results

Example 2: Steps to follow:

1. Create a procedure with one or more select, and DML queries.
2. Call it from java using CallableStatement.
3. You can capture multiple ResultSets executed in procedure.
   DML results can't be captured but can issue another select
   to find how the rows are affected in the table.

Sample table and procedure:

mysql> create table tbl_mq( i int not null auto_increment, name varchar(10), primary key (i) );
Query OK, 0 rows affected (0.16 sec)

mysql> delimiter //
mysql> create procedure multi_query()
    -> begin
    ->  select count(*) as name_count from tbl_mq;
    ->  insert into tbl_mq( names ) values ( 'ravi' );
    ->  select last_insert_id();
    ->  select * from tbl_mq;
    -> end;
    -> //
Query OK, 0 rows affected (0.02 sec)
mysql> delimiter ;
mysql> call multi_query();
+------------+
| name_count |
+------------+
|          0 |
+------------+
1 row in set (0.00 sec)

+------------------+
| last_insert_id() |
+------------------+
|                3 |
+------------------+
1 row in set (0.00 sec)

+---+------+
| i | name |
+---+------+
| 1 | ravi |
+---+------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Call Procedure from Java:

CallableStatement cstmt = con.prepareCall( "call multi_query()" );  
boolean hasMoreResultSets = cstmt.execute();  
READING_QUERY_RESULTS:  
    while ( hasMoreResultSets ) {  
        Resultset rs = stmt.getResultSet();
        // handle your rs here
    } // while has more rs

i tried everything/....but only this thing worked for me:

To fix this, I went to help - Install New Software... - from the "work with" drop-down box I selected http://dl-ssl.google.com/android/eclipse/ - I then check marked "Developer Tools" and hit the Next button. I then followed the prompts and it basically did a re-install. It took less than 5 minutes. That resolved the error.

Now Im back up and running, and I got the lastest version of Eclipse.

Thanks a lot Nadir

The result produced by the Query is having no of rows that need proper handling this issue can be resolved if you provide the valid handler in the query like 1. limiting the query to return one single row 2. this can also be done by providing "select max(column)" that will return the single row

Not sure how you want to represent the tree? Anyway here's an example which scans the entire subtree using recursion. Files and directories are treated alike. Note that File.listFiles() returns null for non-directories.

public static void main(String[] args) {
    Collection<File> all = new ArrayList<File>();
    addTree(new File("."), all);
    System.out.println(all);
}

static void addTree(File file, Collection<File> all) {
    File[] children = file.listFiles();
    if (children != null) {
        for (File child : children) {
            all.add(child);
            addTree(child, all);
        }
    }
}

Java 7 offers a couple of improvements. For example, DirectoryStream provides one result at a time - the caller no longer has to wait for all I/O operations to complete before acting. This allows incremental GUI updates, early cancellation, etc.

static void addTree(Path directory, Collection<Path> all)
        throws IOException {
    try (DirectoryStream<Path> ds = Files.newDirectoryStream(directory)) {
        for (Path child : ds) {
            all.add(child);
            if (Files.isDirectory(child)) {
                addTree(child, all);
            }
        }
    }
}

Note that the dreaded null return value has been replaced by IOException.

Java 7 also offers a tree walker:

static void addTree(Path directory, final Collection<Path> all)
        throws IOException {
    Files.walkFileTree(directory, new SimpleFileVisitor<Path>() {
        @Override
        public FileVisitResult visitFile(Path file, BasicFileAttributes attrs)
                throws IOException {
            all.add(file);
            return FileVisitResult.CONTINUE;
        }
    });
}

As has been suggested, using the string.format method is nice and simple and very readable.

In vb.net the " + " is used for addition and the " & " is used for string concatenation.

In your example:

MsgBox("Variable = " + variable)

becomes:

MsgBox("Variable = " & variable)

I may have been a bit quick answering this as it appears these operators can both be used for concatenation, but recommended use is the "&", source http://msdn.microsoft.com/en-us/library/te2585xw(v=VS.100).aspx

maybe call

variable.ToString()

update:

Use string interpolation (vs2015 onwards I believe):

MsgBox($"Variable = {variable}")

Try this also:

this.log = console.log.bind( console, '[' + new Date().toUTCString() + ']' );

This function puts timestamp, filename and line number as same of built-in console.log.

Use:

sudo chmod 755 -R /whatever/your/directory/is

However, be careful with that. It can really hurt you if you change the permissions of the wrong files/folders.

Here's another way to process command line args, using R CMD BATCH. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.

Here's an R file, which I name test.R:

defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass

## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
  eval(parse(text=arg))

## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
  assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])

print(a)
print(b)

At the command line, if I type

R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R

then within R we'll have a = 2 and b = c(2,5,6). But I could, say, omit b, and add in another argument c:

R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R

Then in R we'll have a = 2, b = c(1,1,1) (the default), and c = "hello".

Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:

## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
  for (arg in commandArgs(TRUE))
    eval(parse(text=arg), envir=envir)

  for (nm in names(defaults))
    assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}

## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))

One of the best component of android architechure introduce by google will fulfill your all the requirement that is ViewModel.

That is designed to store and manage UI related data in lifecycle way plus that will allow data to survive as screen rotates

class MyViewModel : ViewModel() {

Please refer this:https://developer.android.com/topic/libraries/architecture/viewmodel

For what it's worth, some heavy used production code I have written is based on this assumption and I never had a problem with it. I know that doesn't make it true though :-)

If you don't want to take the risk I would use iteritems() if you can.

for key, value in myDictionary.iteritems():
    print key, value

I know this is a bit of an old question, but I've ended up making my own little class for it.

Might be useful to someone so I'll stick it up. I used a class variable, which is inherently persistent, to ensure sufficient whitespace was added to clear any old lines. See below:

class consolePrinter():
'''
Class to write to the console

Objective is to make it easy to write to console, with user able to 
overwrite previous line (or not)
'''
# -------------------------------------------------------------------------    
#Class variables
stringLen = 0    
# -------------------------------------------------------------------------    
    
# -------------------------------------------------------------------------
def writeline(stringIn, overwriteFlag=False):
    import sys
    #Get length of stringIn and update stringLen if needed
    if len(stringIn) > consolePrinter.stringLen:
        consolePrinter.stringLen = len(stringIn)+1
    
    ctrlString = "{:<"+str(consolePrinter.stringLen)+"}"
    if overwriteFlag:
        sys.stdout.write("\r" + ctrlString.format(stringIn))
    else:
        sys.stdout.write("\n" + stringIn)
    sys.stdout.flush()
    
    return

Which then is called via:

consolePrinter.writeline("text here", True) 

If you want to overwrite the previous line, or

consolePrinter.writeline("text here",False)

if you don't.

Note, for it to work right, all messages pushed to the console would need to be through consolePrinter.writeline.

With the Material Components Library you can use the MaterialShapeDrawable to draw custom shapes.

With a EditText you can do:

    <EditText
        android:id="@+id/edittext"
        ../>

Then create a MaterialShapeDrawable:

float radius = getResources().getDimension(R.dimen.default_corner_radius);

EditText editText = findViewById(R.id.edittext);
//Apply the rounded corners 
ShapeAppearanceModel shapeAppearanceModel = new ShapeAppearanceModel()
                .toBuilder()
                .setAllCorners(CornerFamily.ROUNDED,radius)
                .build();

MaterialShapeDrawable shapeDrawable = 
            new MaterialShapeDrawable(shapeAppearanceModel);
//Apply a background color
shapeDrawable.setFillColor(ContextCompat.getColorStateList(this,R.color.white));
//Apply a stroke
shapeDrawable.setStroke(2.0f, ContextCompat.getColor(this,R.color.colorAccent));

ViewCompat.setBackground(editText,shapeDrawable);

It requires the version 1.1.0 of the library.

Cloning Arrays and Objects in javascript have a different syntax. Sooner or later everyone learns the difference the hard way and end up here.

In Typescript and ES6 you can use the spread operator for array and object:

const myClonedArray  = [...myArray];  // This is ok for [1,2,'test','bla']
                                      // But wont work for [{a:1}, {b:2}]. 
                                      // A bug will occur when you 
                                      // modify the clone and you expect the 
                                      // original not to be modified.
                                      // The solution is to do a deep copy
                                      // when you are cloning an array of objects.

To do a deep copy of an object you need an external library:

import {cloneDeep} from 'lodash';
const myClonedArray = cloneDeep(myArray);     // This works for [{a:1}, {b:2}]

The spread operator works on object as well but it will only do a shallow copy (first layer of children)

const myShallowClonedObject = {...myObject};   // Will do a shallow copy
                                               // and cause you an un expected bug.

To do a deep copy of an object you need an external library:

 import {cloneDeep} from 'lodash';
 const deeplyClonedObject = cloneDeep(myObject);   // This works for [{a:{b:2}}]

Mongo's in-built export is working fine, unless you want to any data manipulation like format date, covert data types etc.

Following command works as charm.

    mongoexport -h localhost -d databse -c collection --type=csv 
    --fields erpNum,orderId,time,status 
    -q '{"time":{"$gt":1438275600000}, "status":{"$ne" :"Cancelled"}}' 
    --out report.csv

Here is my summary of this problem: 5 Ways of Calling Java from Python

http://baojie.org/blog/2014/06/16/call-java-from-python/ (cached)

Short answer: Jpype works pretty well and is proven in many projects (such as python-boilerpipe), but Pyjnius is faster and simpler than JPype

I have tried Pyjnius/Jnius, JCC, javabridge, Jpype and Py4j.

Py4j is a bit hard to use, as you need to start a gateway, adding another layer of fragility.

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

• std::optional

  • Maybe holds one of something
  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • std::string like reference-to-character-array or substring
  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

File System TS v1

• [class.path]

• [class.filesystem.error]

• [class.file_status]

• [class.directory_entry]

  • Untimed, which can be more efficient if you don't need it.

• atomic<T>::is_always_lockfree

• scoped_lock<Mutexes...>

  • Saves some std::lock pain when locking more than one mutex at a time.

• Parallelism TS v1

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html

• std::sample, sampling from a range?

Container Improvements

• try_emplace and insert_or_assign

  • gives better guarantees in some cases where spurious move/copy would be bad

• Splicing for map<>, unordered_map<>, set<>, and unordered_set<>

  • Move nodes between containers cheaply.
  • Merge whole containers cheaply.

• non-const .data() for string.

• non-member std::size, std::empty, std::data

  • like std::begin/end

• Minimal incomplete type support in containers

• Contiguous iterator "concept"

• constexpr iterators

• The emplace family of functions now returns a reference to the created object.

Smart pointer changes

• unique_ptr<T[]> fixes and other unique_ptr tweaks.
• weak_from_this and some fixed to shared from this

Other std datatype improvements:

• {} construction of std::tuple and other improvements
• TriviallyCopyable reference_wrapper, can be performance boost

Misc

• Reserved std[0-9]+ for future standard libraries

• destroy(_at|_n), uninitialized_move(_n), uninitialized_value_construct(_n), uninitialized_default_construct(_n)

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Further reference:

• papers grouped by year; not all accepted

• https://isocpp.org/files/papers/p0636r0.html

  • Should be updated to "Modifications to existing features" here.

For those wondering, @edward-coast

If you want to set the keep alive for the server, add this to /etc/ssh/sshd_config:

ClientAliveInterval 60
ClientAliveCountMax 2

ClientAliveInterval: Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client.

ClientAliveCountMax: Sets the number of client alive messages (see below) which may be sent without sshd(8) receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, sshd will disconnect the client, terminating the session.

To keep it basic, I used a loop and something like this to get you started (my index are datetimes):

import pandas as pd
import datetime as dt

#populate your dataframe: "df"
#...

df[df.index<(df.index[0]+dt.timedelta(hours=1))] #gives you a slice. you can then take .sum() .mean(), whatever

and then you can run functions on that slice. You can see how adding an iterator to make the start of the window something other than the first value in your dataframes index would then roll the window (you could use a > rule for the start as well for example).

Note, this may be less efficient for SUPER large data or very small increments as your slicing may become more strenuous (works for me well enough for hundreds of thousands of rows of data and several columns though for hourly windows across a few weeks)

Comprehensions are usually faster, and this has the advantage of not editing mydict during the iteration:

mydict = dict((k, v if v else '') for k, v in mydict.items())

Here is an example of sending back a pdf.

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="' . basename($filename) . '"');
header('Content-Transfer-Encoding: binary');
readfile($filename);

@Swish I didn't find application/force-download content type to do anything different (tested in IE and Firefox). Is there a reason for not sending back the actual MIME type?

Also in the PHP manual Hayley Watson posted:

If you wish to force a file to be downloaded and saved, instead of being rendered, remember that there is no such MIME type as "application/force-download". The correct type to use in this situation is "application/octet-stream", and using anything else is merely relying on the fact that clients are supposed to ignore unrecognised MIME types and use "application/octet-stream" instead (reference: Sections 4.1.4 and 4.5.1 of RFC 2046).

Also according IANA there is no registered application/force-download type.

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

Here is an easy way to understand it

• Your List is an object created on heap. The variable myList is a reference to that object.

• In C# you never pass objects, you pass their references by value.

• When you access the list object via the passed reference in ChangeList (while sorting, for example) the original list is changed.

• The assignment on the ChangeList method is made to the value of the reference, hence no changes are done to the original list (still on the heap but not referenced on the method variable anymore).

Best answer doesn't work for me. I needed ssh:// from the beggining.

# does not work
git remote set-url origin [email protected]:10000/aaa/bbbb/ccc.git
# work
git remote set-url origin ssh://[email protected]:10000/aaa/bbbb/ccc.git

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera
