In case you want to download the repo from your shell/terminal it should work like this:

wget https://user:[email protected]/user-name/repo-name/get/master.tar.bz2

or whatever download URL you might have.

Please make sure the user:password are both URL-encoded. So for instance if your username contains the @ symbol then replace it with %40.

I just got this message and there is a very simple answer before trying the others. At the parent directory, type git init

This will initialize the directory for git. Then git add and git commit should work.

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

Example

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

<tag_name> : 0.37.2

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

I was successful in doing this using file://, but with one additional slash to denote an absolute path.

git clone file:///cygdrive/c/path/to/repository/

In my case I'm using Git on Cygwin for Windows, which you can see because of the /cygdrive/c part in my paths. With some tweaking to the path it should work with any git installation.

Adding a remote works the same way

git remote add remotename file:///cygdrive/c/path/to/repository/

first fetch all the tags in that specific remote

git fetch <remote> 'refs/tags/*:refs/tags/*'

or just simply type

git fetch <remote>

Then check for the available tags

git tag -l

then switch to that specific tag using below command

git checkout tags/<tag_name>

Hope this will helps you!

git clone --branch {branch-name} {repo-URI}

Example:

git clone --branch dev https://github.com/ann/cleaningmachine.git

• dev: This is the {branch-name}
• https://github.com/ann/cleaningmachine.git: This is the {repo-URI}

If the current directory is empty, then this will work:

git clone <repository> foo; mv foo/* foo/.git* .; rmdir foo

git clone git@server:Example/proyect.git

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

You can always do

git clone git://repo.org/fossproject.git && rm -rf fossproject/.git

For other Beginners (like myself) If you are on windows running git as admin also solves the problem.

My tests with git-2.0.0 today indicate that the --mirror option does not copy hooks, the config file, the description file, the info/exclude file, and at least in my test case a few refs (which I don't understand.) I would not call it a "functionally identical copy, interchangeable with the original."

-bash-3.2$ git --version

-bash-3.2$ git clone --mirror /git/hooks

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

If you use BitBucket,

you can use import Repository, this will import all git history ( all the branches and commits)

After changing permissions of folder in which I was cloning, it worked:

sudo chown -R ubuntu:ubuntu /var/projects

What you are trying to do is called a sparse checkout, and that feature was added in git 1.7.0 (Feb. 2012). The steps to do a sparse clone are as follows:

mkdir <repo>
cd <repo>
git init
git remote add -f origin <url>

This creates an empty repository with your remote, and fetches all objects but doesn't check them out. Then do:

git config core.sparseCheckout true

Now you need to define which files/folders you want to actually check out. This is done by listing them in .git/info/sparse-checkout, eg:

echo "some/dir/" >> .git/info/sparse-checkout
echo "another/sub/tree" >> .git/info/sparse-checkout

Last but not least, update your empty repo with the state from the remote:

git pull origin master

You will now have files "checked out" for some/dir and another/sub/tree on your file system (with those paths still), and no other paths present.

You might want to have a look at the extended tutorial and you should probably read the official documentation for sparse checkout.

As a function:

function git_sparse_clone() (
  rurl="$1" localdir="$2" && shift 2

  mkdir -p "$localdir"
  cd "$localdir"

  git init
  git remote add -f origin "$rurl"

  git config core.sparseCheckout true

  # Loops over remaining args
  for i; do
    echo "$i" >> .git/info/sparse-checkout
  done

  git pull origin master
)

Usage:

git_sparse_clone "http://github.com/tj/n" "./local/location" "/bin"

Note that this will still download the whole repository from the server – only the checkout is reduced in size. At the moment it is not possible to clone only a single directory. But if you don't need the history of the repository, you can at least save on bandwidth by creating a shallow clone. See udondan's answer below for information on how to combine shallow clone and sparse checkout.

As of git 2.25.0 (Jan 2020) an experimental sparse-checkout command is added in git:

git sparse-checkout init
# same as: 
# git config core.sparseCheckout true

git sparse-checkout set "A/B"
# same as:
# echo "A/B" >> .git/info/sparse-checkout

git sparse-checkout list
# same as:
# cat .git/info/sparse-checkout

If you've got 2FA enabled on your Github account, your regular password won't work for this purpose, but you can generate a Personal Access Token and use that in its place instead.

Visit the Settings -> Developer Settings -> Personal Access Tokens page in GitHub (https://github.com/settings/tokens/new), and generate a new Token with all Repo permissions:

The page will then display the new token value. Save this value and use it in place of your password when pushing to your repository on GitHub:

> git push origin develop
Username for 'https://github.com': <your username>
Password for 'https://<your username>@github.com': <your personal access token>

I believe this is an old question, and the Traffic was introduced by Github in 2014. Here is the link to the description of Traffic, that tells you the views on your repositories.

None of these worked for me. I am using git-bash on windows. Found out the problem was with my file path formatting.

WRONG:

git clone F:\DEV\MY_REPO\.git

CORRECT:

git clone /F/DEV/MY_REPO/.git

These commands are done from the folder you want the repo folder to appear in.

You can make git replace the protocol for you

git config --global url."https://".insteadOf git://

See more at SO Bower install using only https?

Fork, in the GitHub context, doesn't extend Git.
It only allows clone on the server side.

When you clone a GitHub repository on your local workstation, you cannot contribute back to the upstream repository unless you are explicitly declared as "contributor". That's because your clone is a separate instance of that project. If you want to contribute to the project, you can use forking to do it, in the following way:

• clone that GitHub repository on your GitHub account (that is the "fork" part, a clone on the server side)
• contribute commits to that GitHub repository (it is in your own GitHub account, so you have every right to push to it)
• signal any interesting contribution back to the original GitHub repository (that is the "pull request" part by way of the changes you made on your own GitHub repository)

Check also "Collaborative GitHub Workflow".

If you want to keep a link with the original repository (also called upstream), you need to add a remote referring that original repository.
See "What is the difference between origin and upstream on GitHub?"

And with Git 2.20 (Q4 2018) and more, fetching from fork is more efficient, with delta islands.

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"... :-)

Unlike centralized version control systems, Git clones the entire repository, so you don't only get the current remote files, but the whole history. You local repository will include all this.

There might have been tags to mark a particular version at the time. If not, you can create them yourself locally. A good way to do this is to use git log or perhaps more visually with tools like gitk (perhaps gitk --all to see all the branches and tags). If you can spot the commits hashes that were used at the time, you can tag them using git tag <hash> and then check those out in new working copies (for example git checkout -b new_branch_name tag_name or directly with the hash instead of the tag name).

Your method looks like it would work; the file structure of a bare repository is just what is inside the .git directory. But I don't know if any of the files are actually changed, so if that fails, you can just do

git clone --bare /path/to/repo

You'll probably need to do it in a different directory to avoid a name conflict, and then you can just move it back to where you want. And you may need to change the config file to point to wherever your origin repo is.

Option A:

git clone [email protected]:whatever folder-name

Ergo, for right here use:

git clone [email protected]:whatever .

Option B:

Move the .git folder, too. Note that the .git folder is hidden in most graphical file explorers, so be sure to show hidden files.

mv /where/it/is/right/now/* /where/I/want/it/
mv /where/it/is/right/now/.* /where/I/want/it/

The first line grabs all normal files, the second line grabs dot-files. It is also possibe to do it in one line by enabling dotglob (i.e. shopt -s dotglob) but that is probably a bad solution if you are asking the question this answer answers.

Better yet:

Keep your working copy somewhere else, and create a symbolic link. Like this:

ln -s /where/it/is/right/now /the/path/I/want/to/use

For your case this would be something like:

ln -sfn /opt/projectA/prod/public /httpdocs/public

Which easily could be changed to test if you wanted it, i.e.:

ln -sfn /opt/projectA/test/public /httpdocs/public

without moving files around. Added -fn in case someone is copying these lines (-f is force, -n avoid some often unwanted interactions with already and non-existing links).

If you just want it to work, use Option A, if someone else is going to look at what you have done, use Option C.

Just to sum things up (git v. 1.7.2.1):

1. do a regular git clone where you want the repo (gets everything to date — I know, not what is wanted, we're getting there)
2. git checkout <sha1 rev> of the rev you want
3. git reset --hard
4. git checkout -b master

Here is a really simple way to do it :)

Clone the repository

git clone <repository_url>

List all branches

git branch -a 

Checkout the branch that you want

git checkout <name_of_branch>

Here is Oliver Steele's image of how it all fits together:

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

I would suggest you to test it firstly: copy this train.csv to the same directory as this jupyter script in and then change the path to train.csv to test whether this can be loaded successfully.

If yes, that means the previous path input is a problem

If not, that means the file it self denied your access to it, or its real filename can be something else like: train.csv.<hidden extension>

tl;dr: JavaScript doesn't support associative arrays, therefore neither does JSON.

After all, it's JSON, not JSAAN. :)

So PHP has to convert your array into an object in order to encode into JSON.

I was getting this exact same error. I ran the command

./gradlew assembleDebug --info

Where "assembleDebug" was replaced with the assemble task for a debug version of the flavor I wanted.

Look for output

Right below that was an error describing a resource which I used in a layout file but which was missing from the dimensions files. Fixing this fixed the build issue.

As mentioned by aloisdg below, editor.renderWhitespace is now an enum taking either none, boundary or all. To view all whitespaces:

"editor.renderWhitespace": "all", 

Before VS Code 1.6.0

Before 1.6.0, you had to set editor.renderWhitespace to true:

Hope the below example will help,

echo ${name:0:$((${#name}-10))} --> ${name:start:len}

• In above command, name is the variable.
• start is the string starting point
• len is the length of string that has to be removed.

Example:

    read -p "Enter:" name
    echo ${name:0:$((${#name}-10))}

Output:

    Enter:Siddharth Murugan
    Siddhar

Note: Bash 4.2 added support for negative substring

I'm posting this as an answer in case you are like me and cannot figure out why the range type input doesn't work on ANY mobile browsers. If you develop mobile apps on your laptop and use the responsive mode to emulate touch, you will notice the range doesn't even move when you have the touch simulator activated. It starts moving when you deactivate it. I went on for 2 days trying every piece of code I could find on the subject and could not make it work for the life of me. I provide a WORKING solution in this post.

Mobile Browsers And Hybrid Apps

Mobile browsers run using a component called Webkit for iOS and WebView for Android. The WebView/WebKit enables you to embed a web browser, which does not have any chrome or firefox (browser) controls including window frames, menus, toolbars and scroll bars into your activity layout. In other words, mobile browsers lack a lot of web components normally found in regular browsers. This is the problem with the range type input. If the user's browser doesn't support range type, it will fall back and treat it as a text input. This is why you cannot move the range when the touch simulator is activated.

Read more here on browser compatibility

jQuery Slider

jQuery provides a slider that somehow works with touch simulation but it is choppy and not very smooth. It wasn't satisfying to me and it probably wont be for you either but you can make it work more smoothly if you combine it with jqueryUi.

Best Solution : Range Touch

If you develop hybrid apps on your laptop, there is a simple and easy library you can use to enable range type input to work with touch events.

This library is called Range Touch.

DataTable, DbDataReader, or IEnumerable<SqlDataRecord> objects can be used to populate a table-valued parameter per the MSDN article Table-Valued Parameters in SQL Server 2008 (ADO.NET).

The following example illustrates using either a DataTable or an IEnumerable<SqlDataRecord>:

SQL Code:

CREATE TABLE dbo.PageView
(
    PageViewID BIGINT NOT NULL CONSTRAINT pkPageView PRIMARY KEY CLUSTERED,
    PageViewCount BIGINT NOT NULL
);
CREATE TYPE dbo.PageViewTableType AS TABLE
(
    PageViewID BIGINT NOT NULL
);
CREATE PROCEDURE dbo.procMergePageView
    @Display dbo.PageViewTableType READONLY
AS
BEGIN
    MERGE INTO dbo.PageView AS T
    USING @Display AS S
    ON T.PageViewID = S.PageViewID
    WHEN MATCHED THEN UPDATE SET T.PageViewCount = T.PageViewCount + 1
    WHEN NOT MATCHED THEN INSERT VALUES(S.PageViewID, 1);
END

C# Code:

private static void ExecuteProcedure(bool useDataTable, 
                                     string connectionString, 
                                     IEnumerable<long> ids) 
{
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    {
        connection.Open();
        using (SqlCommand command = connection.CreateCommand()) 
        {
            command.CommandText = "dbo.procMergePageView";
            command.CommandType = CommandType.StoredProcedure;

            SqlParameter parameter;
            if (useDataTable) {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateDataTable(ids));
            }
            else 
            {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateSqlDataRecords(ids));
            }
            parameter.SqlDbType = SqlDbType.Structured;
            parameter.TypeName = "dbo.PageViewTableType";

            command.ExecuteNonQuery();
        }
    }
}

private static DataTable CreateDataTable(IEnumerable<long> ids) 
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(long));
    foreach (long id in ids) 
    {
        table.Rows.Add(id);
    }
    return table;
}

private static IEnumerable<SqlDataRecord> CreateSqlDataRecords(IEnumerable<long> ids) 
{
    SqlMetaData[] metaData = new SqlMetaData[1];
    metaData[0] = new SqlMetaData("ID", SqlDbType.BigInt);
    SqlDataRecord record = new SqlDataRecord(metaData);
    foreach (long id in ids) 
    {
        record.SetInt64(0, id);
        yield return record;
    }
}

You need to add a CDATA tag inside of the script tag, unless you want to manually go through and escape all XHTML characters (e.g. & would need to become &). For example:

<script>
//<![CDATA[
var el = document.getElementById("pacman");

if (Modernizr.canvas && Modernizr.localstorage && 
    Modernizr.audio && (Modernizr.audio.ogg || Modernizr.audio.mp3)) {
  window.setTimeout(function () { PACMAN.init(el, "./"); }, 0);
} else { 
  el.innerHTML = "Sorry, needs a decent browser<br /><small>" + 
    "(firefox 3.6+, Chrome 4+, Opera 10+ and Safari 4+)</small>";
}
//]]>
</script>

$('body').on("click mousedown mouseup focus blur keydown change mouseup click dblclick mousemove mouseover mouseout mousewheel keydown keyup keypress textInput touchstart touchmove touchend touchcancel resize scroll zoom focus blur select change submit reset",function(e){
     console.log(e);
});

If you want to avoid using an extra Class and List<Object> genomes you could simply use a Map.

The data structure translates into Map<String, List<Country>>

String resourceEndpoint = "http://api.geonames.org/countryInfoJSON?username=volodiaL";

Map<String, List<Country>> geonames = restTemplate.getForObject(resourceEndpoint, Map.class);

List<Country> countries = geonames.get("geonames");

I've slightly modified Jaymon's answer for people who want really simple validation in the form of:

[email protected]

The regular expression:

/\S+@\S+\.\S+/

To prevent matching multiple @ signs:

/^[^\s@]+@[^\s@]+$/

Example JavaScript function:

function validateEmail(email) 
    {
        var re = /\S+@\S+\.\S+/;
        return re.test(email);
    }
    
console.log(validateEmail('[email protected]'));

in my case it helped to remove the lines build.gradle

I don't know why this happens, but after adding the specified library, the compiled jar stops working

You Should know about "this" Keyword.

As per my view you can implement "this" in three ways (Self/Arrow function/Bind Method)

A function's this keyword behaves a little differently in JavaScript compared to other languages.

It also has some differences between strict mode and non-strict mode.

In most cases, the value of this is determined by how a function is called.

It can't be set by assignment during execution, and it may be different each time the function is called.

ES5 introduced the bind() method to set the value of a function's this regardless of how it's called,

and ES2015 introduced arrow functions which don't provide their own this binding (it retains this value of the enclosing lexical context).

Method1: Self - Self is being used to maintain a reference to the original this even as the context is changing. It's a technique often used in event handlers (especially in closures).

Reference : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/this

function MyConstructor(data, transport) {
    this.data = data;
    var self = this;
    transport.on('data', function () {
        alert(self.data);
    });
}

Method2: Arrow function - An arrow function expression is a syntactically compact alternative to a regular function expression,

although without its own bindings to the this, arguments, super, or new.target keywords.

Arrow function expressions are ill-suited as methods, and they cannot be used as constructors.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions

  function MyConstructor(data, transport) {
    this.data = data;
    transport.on('data',()=> {
        alert(this.data);
    });
}

Method3:Bind- The bind() method creates a new function that,

when called, has its this keyword set to the provided value,

with a given sequence of arguments preceding any provided when the new function is called.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_objects/Function/bind

  function MyConstructor(data, transport) {
    this.data = data;
    transport.on('data',(function() {
        alert(this.data);
    }).bind(this);

 -(BOOL)textFieldShouldReturn:(UITextField *)textField
{
   [[self.view viewWithTag:textField.tag+1] becomeFirstResponder];
   return YES;
}

Change host: localhost in config/database.yml to host: 127.0.0.1 to make rails connect over TCP/IP instead of local socket.

development:
  adapter: mysql2
  host: 127.0.0.1
  username: root
  password: xxxx
  database: xxxx

Here's the example:

// Test
public void foo() {
    C c = new C();
    A s;
    s = ((A.B)c).get();
    System.out.println(s.getR());
}

// classes
class C {}

class A {
   public class B extends C{
     A get() {return A.this;}
   }
   public String getR() {
     return "This is string";
   }
}

Add the following 2 lines

var regex = new Regex(Regex.Escape(","));
sb_trim = regex.Replace(sb_trim, " ", 1);

If sb_trim= John,Smith,100000,M the above code will return "John Smith,100000,M"

I finally got this working.

I think the fact that our project had two different versions of the commons-httpclient jar wasn't helping. Once I sorted that out I found you can do two things...

HttpComponentsClientHttpRequestFactory rf =
    (HttpComponentsClientHttpRequestFactory) restTemplate.getRequestFactory();
rf.setReadTimeout(1 * 1000);
rf.setConnectTimeout(1 * 1000);

The first time this code is called it will set the timeout for the HttpComponentsClientHttpRequestFactory class used by the RestTemplate. Therefore, all subsequent calls made by RestTemplate will use the timeout settings defined above.

Or the better option is to do this:

<bean id="RestOperations" class="org.springframework.web.client.RestTemplate">
    <constructor-arg>
        <bean class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
            <property name="readTimeout" value="${application.urlReadTimeout}" />
            <property name="connectTimeout" value="${application.urlConnectionTimeout}" />
        </bean>
    </constructor-arg>
</bean>

Where I use the RestOperations interface in my code and get the timeout values from a properties file.

df.ix[10,:] gives you all the columns from the 10th row. In your case you want everything up to the 10th row which is df.ix[:9,:]. Note that the right end of the slice range is inclusive: http://pandas.sourceforge.net/gotchas.html#endpoints-are-inclusive

Add one more line after initializing file object

File fnew = new File("../playlist/" + existingPlaylist.getText() + ".txt");
fnew.createNewFile();

Create an object and push that object into an array

 var jSONdataHolder = function(country, lat, lon) {

    this.country = country;
    this.lat = lat;
    this.lon = lon;
}

var jSONholderArr = [];

jSONholderArr.push(new jSONdataHolder("Sweden", "60", "17"));
jSONholderArr.push(new jSONdataHolder("Portugal", "38", "9"));
jSONholderArr.push(new jSONdataHolder("Brazil", "23", "-46"));

var nObj = jSONholderArr.length;
for (var i = 0; i < nObj; i++) {
   console.log(jSONholderArr[i].country + "; " + jSONholderArr[i].lat + "; " + 
   jSONholderArr[i].lon);

}

I know this is old but if you do a split then join it will remove all occurrences of a particular character ie:

var str = theText.split('A').join('')

will remove all occurrences of 'A' from the string, obviously it's not case sensitive

Working for me with this line (simply add --listen when running) :

node server.js -p 3000 -a : --listen 192.168.1.100

Hope it helps...

This is essentially the answer that Yishai provided above, re-written in Kotlin :

@RunWith(Parameterized::class)
class MyTest {

    companion object {

        private const val numberOfTests = 200

        @JvmStatic
        @Parameterized.Parameters
        fun data(): Array<Array<Any?>> = Array(numberOfTests) { arrayOfNulls<Any?>(0) }
    }

    @Test
    fun testSomething() { }
}

Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.

This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).

Try the following steps:

1. Make sure you have connectivity (you can browse) (This kind of error is usually due to connectivity with Internet)

2. Download Maven and unzip it

3. Create a JAVA_HOME System Variable

4. Create an M2_HOME System Variable

5. Add %JAVA_HOME%\bin;%M2_HOME%\bin; to your PATH variable

6. Open a command window cmd. Check: mvn -v

7. If you have a proxy, you will need to configure it

http://maven.apache.org/guides/mini/guide-proxies.html

8. Make sure you have .m2/repository (erase all the folders and files below)

9. If you are going to use Eclipse, You will need to create the settings.xml

Maven plugin in Eclipse - Settings.xml file is missing

You can see more detail in

http://maven.apache.org/ref/3.2.5/maven-settings/settings.html

if ($elem.parents('.left').length) {

}

I usually prefer .replace() to regular expressions when possible, since it's often easier to read: http://jsfiddle.net/mblase75/z2jKA/2

    $("div").click(function() {
        var bg = $(this).css('background-image');
        bg = bg.replace('url(','').replace(')','').replace(/\"/gi, "");
        alert(bg);
    });

A foreach loop calls the GetEnumerator method.
If the collection is null, this method call results in a NullReferenceException.

It is bad practice to return a null collection; your methods should return an empty collection instead.

It maybe work looking at Character recoqnition software as there are many libraries out there that perform the same thing. I reading an image and storing it. Micrsoft office is able to read tiff files and return alphanumerics

There is a CSS3 property for this, namely background-size (compatibility check). While one can set length values, it's usually used with the special values contain and cover. In your specific case, you should use cover:

body {
    background-image:    url(images/background.svg);
    background-size:     cover;                      /* <------ */
    background-repeat:   no-repeat;
    background-position: center center;              /* optional, center the image */
}

Eggsplanation for contain and cover

Sorry for the bad pun, but I'm going to use the picture of the day by Biswarup Ganguly for demonstration. Lets say that this is your screen, and the gray area is outside of your visible screen. For demonstration, I'm going to assume a 16x9 ratio.

We want to use the aforementioned picture of the day as a background. However, we cropped the image to 4x3 for some reason. We could set the background-size property to some fixed length, but we will focus on contain and cover. Note that I also assume that we didn't mangle the width and/or height of body.

contain

contain

Scale the image, while preserving its intrinsic aspect ratio (if any), to the largest size such that both its width and its height can fit inside the background positioning area.

This makes sure that the background image is always completely contained in the background positioning area, however, there could be some empty space filled with your background-color in this case:

cover

cover

Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area.

This makes sure that the background image is covering everything. There will be no visible background-color, however depending on the screen's ratio a great part of your image could be cut off:

This will turn all returns into HTML

str = str.replace(/(?:\r\n|\r|\n)/g, '<br>');

In case you wonder what ?: means. It is called a non-capturing group. It means that group of regex within the parentheses won't be saved in memory to be referenced later. You can check out these threads for more information:
https://stackoverflow.com/a/11530881/5042169 https://stackoverflow.com/a/36524555/5042169

This works well for specific articles where the text is all wrapped in <p> tags. Since the web is an ugly place, it's not always the case.

Often, websites will have text scattered all over, wrapped in different types of tags (e.g. maybe in a <span> or a <div>, or an <li>).

To find all text nodes in the DOM, you can use soup.find_all(text=True).

This is going to return some undesired text, like the contents of <script> and <style> tags. You'll need to filter out the text contents of elements you don't want.

blacklist = [
  'style',
  'script',
  # other elements,
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name not in blacklist]

If you are working with a known set of tags, you can tag the opposite approach:

whitelist = [
  'p'
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name in whitelist]

with $.getJSON()) there is no any error callback only you can track succeed callback and there no standard setting supported like beforeSend, statusCode, mimeType etc, if you want it use $.ajax().

Because it's more common to call range(0, 10) which returns [0,1,2,3,4,5,6,7,8,9] which contains 10 elements which equals len(range(0, 10)). Remember that programmers prefer 0-based indexing.

Also, consider the following common code snippet:

for i in range(len(li)):
    pass

Could you see that if range() went up to exactly len(li) that this would be problematic? The programmer would need to explicitly subtract 1. This also follows the common trend of programmers preferring for(int i = 0; i < 10; i++) over for(int i = 0; i <= 9; i++).

If you are calling range with a start of 1 frequently, you might want to define your own function:

>>> def range1(start, end):
...     return range(start, end+1)
...
>>> range1(1, 10)
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Here is some PowerShell that creates a single TypeScript definition file a library that includes multiple *.js files with modern JavaScript.

First, change all the extensions to .ts.

Get-ChildItem | foreach { Rename-Item $_ $_.Name.Replace(".js", ".ts") }

Second, use the TypeScript compiler to generate definition files. There will be a bunch of compiler errors, but we can ignore those.

Get-ChildItem | foreach { tsc $_.Name  }

Finally, combine all the *.d.ts files into one index.d.ts, removing the import statements and removing the default from each export statement.

Remove-Item index.d.ts; 

Get-ChildItem -Path *.d.ts -Exclude "Index.d.ts" | `
  foreach { Get-Content $_ } | `
  where { !$_.ToString().StartsWith("import") } | `
  foreach { $_.Replace("export default", "export") } | `
  foreach { Add-Content index.d.ts $_ }

This ends with a single, usable index.d.ts file that includes many of the definitions.

So to upgrade scikit-learn package, you have to follow below process

Step-1: Open your terminal(Ctrl+Alt+t)

Step-2: Now for checking currently installed packages along with the versions installed on your conda environment by typing conda list

Step-3: Now for upgrade type below command

conda update scikit-learn

Hope it helps!!

I'd recommend that you take a look at java.util.ResourceBundle. You should care about I18N, but it's worth it even if you don't. Externalizing the messages is a very good idea. I've found that it was useful to be able to give a spreadsheet to business folks that allowed them to put in the exact language they wanted to see. We wrote an Ant task to generate the .properties files at compile time. It makes I18N trivial.

If you're also using Spring, so much the better. Their MessageSource class is useful for these sorts of things.

There is no static Equals method in the Array class, so what you are using is actually Object.Equals, which determines if the two object references point to the same object.

If you want to check if the arrays contains the same items in the same order, you can use the SequenceEquals extension method:

childe1.SequenceEqual(grandFatherNode)

Edit:

To use SequenceEquals with multidimensional arrays, you can use an extension to enumerate them. Here is an extension to enumerate a two dimensional array:

public static IEnumerable<T> Flatten<T>(this T[,] items) {
  for (int i = 0; i < items.GetLength(0); i++)
    for (int j = 0; j < items.GetLength(1); j++)
      yield return items[i, j];
}

Usage:

childe1.Flatten().SequenceEqual(grandFatherNode.Flatten())

If your array has more dimensions than two, you would need an extension that supports that number of dimensions. If the number of dimensions varies, you would need a bit more complex code to loop a variable number of dimensions.

You would of course first make sure that the number of dimensions and the size of the dimensions of the arrays match, before comparing the contents of the arrays.

Edit 2:

Turns out that you can use the OfType<T> method to flatten an array, as RobertS pointed out. Naturally that only works if all the items can actually be cast to the same type, but that is usually the case if you can compare them anyway. Example:

childe1.OfType<Person>().SequenceEqual(grandFatherNode.OfType<Person>())

I have found a nice way around it:

// The test, BDD style
it ("unsupported site", () => {
    The.function(myFunc)
    .with.arguments({url:"https://www.ebay.com/"})
    .should.throw(/unsupported/);
});


// The function that does the magic: (lang:TypeScript)
export const The = {
    'function': (func:Function) => ({
        'with': ({
            'arguments': function (...args:any) {
                return () => func(...args);
            }
        })
    })
};

It's much more readable then my old version:

it ("unsupported site", () => {
    const args = {url:"https://www.ebay.com/"}; //Arrange
    function check_unsupported_site() { myFunc(args) } //Act
    check_unsupported_site.should.throw(/unsupported/) //Assert
});

About answer 3 removing only the last \n off string code :

if (!s.empty() && s[s.length()-1] == '\n') {
    s.erase(s.length()-1);
}

Will the if condition not fail if the string is really empty ?

Is it not better to do :

if (!s.empty())
{
    if (s[s.length()-1] == '\n')
        s.erase(s.length()-1);
}

This is what I used to start and stop tomcat 7.0.29, using ant 1.8.2. Works fine for me, but leaves the control in the started server window. I have not tried it yet, but I think if I change the "/K" in the startup sequence to "/C", it may not even do that.

<target name="tomcat-stop">
    <exec dir="${appserver.home}/bin" executable="cmd">
        <arg line="/C start cmd.exe /C shutdown.bat"/>
    </exec>
</target>



<target name="tomcat-start" depends="tomcat-stop" >

It was already pointed in this comment and in this answer, but I'll try to give a more direct answer to the question:

from IPython.display import display
import numpy as np
import pandas as pd

n = 100
foo = pd.DataFrame(index=range(n))
foo['floats'] = np.random.randn(n)

with pd.option_context("display.max_rows", foo.shape[0]):
    display(foo)

pandas.option_context is available since pandas 0.13.1 (pandas 0.13.1 release notes). According to this,

[it] allow[s] you to execute a codeblock with a set of options that revert to prior settings when you exit the with block.

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).

Here's is its (succinct and precise) description from GitHub;

HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.

It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

The documentation around authentication should give you enough pointers to solve your problem(s). Of course, all of the answers above are accurate as well, and provide different ways of accomplishing the same task.

Just so you do NOT have to move away from Stack Overflow, here's what it offers in a nutshell.

Basic auth:_x000D_
_x000D_
$ http -a username:password example.org_x000D_
Digest auth:_x000D_
_x000D_
$ http --auth-type=digest -a username:password example.org_x000D_
With password prompt:_x000D_
_x000D_

The foreach loops work just fine, but you can also simply

print_r($_POST);

Or for pretty printing in a browser:

echo "<pre>";
print_r($_POST);
echo "</pre>";

Lexical scope refers to the lexicon of identifiers (e.g., variables, functions, etc.) visible from the current position in the execution stack.

- global execution context
    - foo
    - bar
    - function1 execution context
        - foo2
        - bar2
        - function2 execution context
            - foo3
            - bar3

foo and bar are always within the lexicon of available identifiers because they are global.

When function1 is executed, it has access to a lexicon of foo2, bar2, foo, and bar.

When function2 is executed, it has access to a lexicon of foo3, bar3, foo2, bar2, foo, and bar.

The reason global and/or outer functions do not have access to an inner functions identifiers is because the execution of that function has not occurred yet and therefore, none of its identifiers have been allocated to memory. What’s more, once that inner context executes, it is removed from the execution stack, meaning that all of it’s identifiers have been garbage collected and are no longer available.

Finally, this is why a nested execution context can ALWAYS access it’s ancestors execution context and thus why it has access to a greater lexicon of identifiers.

Special thanks to @robr3rd for help simplifying the above definition.

Well for me, I deleted the file in the libs folder called android support v4.jar and it all worked out. Goodluck :)

Just see the below code snippet if you are implementing a REST API through express and mongoose. (Example for ADD)

...._x000D_
exports.AddSomething = (req,res,next) =>{_x000D_
  const newSomething = new SomeEntity({_x000D_
 _id:new mongoose.Types.ObjectId(), //its very own ID_x000D_
  somethingName:req.body.somethingName,_x000D_
  theForeignKey: mongoose.Types.ObjectId(req.body.theForeignKey)// if you want to pass an object ID_x000D_
})_x000D_
}_x000D_
...

Hope it Helps

I just wrote this and it looks more clean to me:

const fs = require('fs');
const util = require('util');

const readdir = util.promisify(fs.readdir);
const readFile = util.promisify(fs.readFile);

const readFiles = async dirname => {
    try {
        const filenames = await readdir(dirname);
        console.log({ filenames });
        const files_promise = filenames.map(filename => {
            return readFile(dirname + filename, 'utf-8');
        });
        const response = await Promise.all(files_promise);
        //console.log({ response })
        //return response
        return filenames.reduce((accumlater, filename, currentIndex) => {
            const content = response[currentIndex];
            accumlater[filename] = {
                content,
            };
            return accumlater;
        }, {});
    } catch (error) {
        console.error(error);
    }
};

const main = async () => {

    const response = await readFiles(
        './folder-name',
    );
    console.log({ response });
};

You can modify the response format according to your need. The response format from this code will look like:

{
   "filename-01":{
      "content":"This is the sample content of the file"
   },
   "filename-02":{
      "content":"This is the sample content of the file"
   }
}

The below command will work if you want create a new user give him all the access to a specific database(not all databases in your Mysql) on your localhost.

GRANT ALL PRIVILEGES ON test_database.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This will grant all privileges to one database test_database (in your case dbTest) to that user on localhost.

Check what permissions that above command issued to that user by running the below command.

SHOW GRANTS FOR 'user'@'localhost'

Just in case, if you want to limit the user access to only one single table

GRANT ALL ON mydb.table_name TO 'someuser'@'host';

?If you use Eclipse Collections, you can use a Bag. A MutableBag can be returned from any implementation of RichIterable by calling toBag().

MutableList<String> animals = Lists.mutable.with("bat", "owl", "bat", "bat");
MutableBag<String> bag = animals.toBag();
Assert.assertEquals(3, bag.occurrencesOf("bat"));
Assert.assertEquals(1, bag.occurrencesOf("owl"));

The HashBag implementation in Eclipse Collections is backed by a MutableObjectIntMap.

Note: I am a committer for Eclipse Collections.

that's why Idon't like NULL values in the database at all.
I hope you are having it for a reason.

if ($_POST['location_id'] === '') {
  $location_id = 'NULL';
} else {
  $location_id = "'".$_POST['location_id']."'";
}
$notes = mysql_real_escape_string($_POST['notes']);
$ipid  = mysql_real_escape_string($_POST['ipid']);

$sql="UPDATE addresses 
    SET notes='$notes', location_id=$location_id
    WHERE ipid = '$ipid'";

echo $sql; //to see different queries this code produces
// and difference between NULL and 'NULL' in the query

Visual Studio does elevate itself automatically if the project's application manifest specifies an administrative requestedExecutionLevel, so you just need to edit that. Visual Studio will detect that and relaunch itself as administrator when needed.

Building on the original tweet from @rustyshelf, and illustrated answer from iDevzilla, here's a solution that silences the noise from the simulator without disabling NSLog output from the device.

1. Under Product > Scheme > Edit Scheme... > Run (Debug), set the OS_ACTIVITY_MODE environment variable to ${DEBUG_ACTIVITY_MODE} so it looks like this:

2. Go to your project build settings, and click + to add a User-Defined Setting named DEBUG_ACTIVITY_MODE. Expand this setting and Click the + next to Debug to add a platform-specific value. Select the dropdown and change it to "Any iOS Simulator". Then set its value to "disable" so it looks like this:

ngAfterViewInit() of AppComponent is a lifecycle callback Angular calls after the root component and it's children have been rendered and it should fit for your purpose.

I see this hasn't been answered as final.

I see you have max-width as 100% and width as 600. Flip those.

A simple way also is:

     <img src="image.png" style="max-width:600px;width:100%">

I use this often, and then you can control individual images as well, and not have it on all img tags. You could CSS it also like below.

 .image600{
     width:100%;
     max-width:600px;
 }

     <img src="image.png" class="image600">

From near the beginning of the PIL Tutorial:

Once you have an instance of the Image class, you can use the methods defined by this class to process and manipulate the image. For example, let's display the image we just loaded:

     >>> im.show()

Update:

Nowadays theImage.show() method is formally documented in the Pillow fork of PIL along with an explanation of how it's implemented on different OSs.

Here is a solution in case you use jquery and Facebook Asynchronous Lazy Loading:

// listen to an Event
$(document).bind('fbInit',function(){
    console.log('fbInit complete; FB Object is Available');
});

// FB Async
window.fbAsyncInit = function() {
    FB.init({appId: 'app_id', 
         status: true, 
         cookie: true,
         oauth:true,
         xfbml: true});

    $(document).trigger('fbInit'); // trigger event
};

Install same version javac as your JRE

yum install java-devel

I use:

function isString(s) {
    return typeof(s) === 'string' || s instanceof String;
}

Because in JavaScript strings can be literals or objects.

Update:

• This is not a bug.
• Please stop returning View() from a POST action. Use PRG instead and redirect to a GET if the action is a success.
• If you are returning a View() from a POST action, do it for form validation, and do it the way MVC is designed using the built in helpers. If you do it this way then you shouldn't need to use .Clear()
• If you're using this action to return ajax for a SPA, use a web api controller and forget about ModelState since you shouldn't be using it anyway.

Old answer:

ModelState in MVC is used primarily to describe the state of a model object largely with relation to whether that object is valid or not. This tutorial should explain a lot.

Generally you should not need to clear the ModelState as it is maintained by the MVC engine for you. Clearing it manually might cause undesired results when trying to adhere to MVC validation best practises.

It seems that you are trying to set a default value for the title. This should be done when the model object is instantiated (domain layer somewhere or in the object itself - parameterless ctor), on the get action such that it goes down to the page the 1st time or completely on the client (via ajax or something) so that it appears as if the user entered it and it comes back with the posted forms collection. Some how your approach of adding this value on the receiving of a forms collection (in the POST action // Edit) is causing this bizarre behaviour that might result in a .Clear() appearing to work for you. Trust me - you don't want to be using the clear. Try one of the other ideas.

date column 1:

=formatdatetime(today)

Using auxiliary Result class to track if node is found and current k.

public class KthSmallestElementWithAux {

public int kthsmallest(TreeNode a, int k) {
    TreeNode ans = kthsmallestRec(a, k).node;
    if (ans != null) {
        return ans.val;
    } else {
        return -1;
    }
}

private Result kthsmallestRec(TreeNode a, int k) {
    //Leaf node, do nothing and return
    if (a == null) {
        return new Result(k, null);
    }

    //Search left first
    Result leftSearch = kthsmallestRec(a.left, k);

    //We are done, no need to check right.
    if (leftSearch.node != null) {
        return leftSearch;
    }

    //Consider number of nodes found to the left
    k = leftSearch.k;

    //Check if current root is the solution before going right
    k--;
    if (k == 0) {
        return new Result(k - 1, a);
    }

    //Check right
    Result rightBalanced = kthsmallestRec(a.right, k);

    //Consider all nodes found to the right
    k = rightBalanced.k;

    if (rightBalanced.node != null) {
        return rightBalanced;
    }

    //No node found, recursion will continue at the higher level
    return new Result(k, null);

}

private class Result {
    private final int k;
    private final TreeNode node;

    Result(int max, TreeNode node) {
        this.k = max;
        this.node = node;
    }
}
}

You can try with the tool "SQL Database Migration Wizard". This tool provide option to import and export data from azure sql.

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

This is certainly a change from Beta to RC. In the example provided in the question, you now need to decorate your action with [HttpGet] or [AcceptVerbs("GET")].

This causes a problem if you want to mix verb based actions (i.e. "GetSomething", "PostSomething") with non verb based actions. If you try to use the attributes above, it will cause a conflict with any verb based action in your controller. One way to get arount that would be to define separate routes for each verb, and set the default action to the name of the verb. This approach can be used for defining child resources in your API. For example, the following code supports: "/resource/id/children" where id and children are optional.

        context.Routes.MapHttpRoute(
           name: "Api_Get",
           routeTemplate: "{controller}/{id}/{action}",
           defaults: new { id = RouteParameter.Optional, action = "Get" },
           constraints: new { httpMethod = new HttpMethodConstraint("GET") }
        );

        context.Routes.MapHttpRoute(
           name: "Api_Post",
           routeTemplate: "{controller}/{id}/{action}",
           defaults: new { id = RouteParameter.Optional, action = "Post" },
           constraints: new { httpMethod = new HttpMethodConstraint("POST") }
        );

Hopefully future versions of Web API will have better support for this scenario. There is currently an issue logged on the aspnetwebstack codeplex project, http://aspnetwebstack.codeplex.com/workitem/184. If this is something you would like to see, please vote on the issue.

I managed to get this done using Jackson in Spring 5. Depending on the object Jackson might not work in all cases.

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

ObjectMapper mapper = new ObjectMapper();
Staff staff = createStaff();
// pretty print
String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(staff);
System.out.println("-------------------------------------------------------------------")
System.out.println(json);
System.out.println("-------------------------------------------------------------------")

the output would be something like

-------------------------------------------------------------------
{
  "id" : 1,
  "internalStaffId" : "1",
  "staffCms" : 1,
  "createdAt" : "1",
  "updatedAt" : "1",
  "staffTypeChange" : null,
  "staffOccupationStatus" : null,
  "staffNote" : null
}
-------------------------------------------------------------------

More examples using Jackson here

You can try GSON also. Should be something like this:

Gson gson = new Gson();
System.out.println(gson.toJson(objectYouWantToPrint).toString());

    mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
        @Override
        public void onMyLocationChange(Location location) {

                CameraUpdate center=CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
                CameraUpdate zoom=CameraUpdateFactory.zoomTo(11);
                mMap.moveCamera(center);
                mMap.animateCamera(zoom);

        }
    });

Use this code it will help you.

<script>
InitializeDate();
</script>




<input type="text" id="txtFromDate" class="datepicker calendar-icon" placeholder="From Date" style="width: 100px; margin-right: 10px; padding: 0px 0px 0px 7px;">
        <input type="text" id="txtToDate" class="datepicker calendar-icon" placeholder="To Date" style="width: 100px; margin-right: 10px; padding: 0px 0px 0px 7px;">


function InitializeDate() {
    var date = new Date();
    var dd = date.getDate();             
    var mm = date.getMonth() + 1;
    var yyyy = date.getFullYear();

    var ToDate = mm + '/' + dd + '/' + yyyy;
    var FromDate = mm + '/01/' + yyyy;
    $('#txtToDate').datepicker('setDate', ToDate);
    $('#txtFromDate').datepicker('setDate', FromDate);
}

For Xamarin.Android

float DpToPixel(float dp)
{
    var resources = Context.Resources;
    var metrics = resources.DisplayMetrics;
    return dp * ((float)metrics.DensityDpi / (int)DisplayMetricsDensity.Default);
}

Making this a non-static is necessary when you're making a custom renderer

A List and Map are conceptually different. A List is an ordered collection of items. The items can contain duplicates, and an item might not have any concept of a unique identifier (key). A Map has values mapped to keys. Each key can only point to one value.

Therefore, depending on your List's items, it may or may not be possible to convert it to a Map. Does your List's items have no duplicates? Does each item have a unique key? If so then it's possible to put them in a Map.

You can use XDocument.Parse for this.

If I were you I would use conditional compilation or feature detection.
Here's another alternative:

<!--[if lt IE 9]><!-->
<script>
    var LTEIE8 = true;
</script>
<!--<![endif]-->

In MVC 5 I found that temporarily commenting out references to an Entity Framework model, and recompiling the project side stepped this error when scaffolding. Once I finish scaffolding I uncomment the code.

public Guid CreatedById { get; private set; }
// Commented out so I can scaffold: 
// public virtual UserBase CreatedBy { get; private set; }

The command git config --list will list the settings. There you should also find user.name and user.email.

Just came across the same problem on a freshly installed CentOS 6.4 64-bit machine. A single yum command will fix this plus 99% of similar problems:

yum groupinstall "Compatibility libraries"

Either prefix this with 'sudo' or run as root, whichever works best for you.

Add it in database migrations, that way everyone gets it as they update. Handle all of your logic in the ruby/rails code, so you never have to mess with explicit ID settings.

git revert HEAD -m 1

In the above code line. "Last argument represents"

• 1 - reverts one commits. 2 - reverts last commits. n - reverts last n commits

or

git reset --hard siriwjdd

This will make an orange and gray border using the class="myclass" on the div.

.myclass {
    outline:dashed darkorange  12px;
    border:solid slategray  14px;
    outline-offset:-14px;
}

Override OnFormClosing?

use it:

.CopyToDataTable()

example:

string _sqlWhere = "Nachname = 'test'";
string _sqlOrder = "Nachname DESC";

DataTable _newDataTable = yurDateTable.Select(_sqlWhere, _sqlOrder).CopyToDataTable();

I had the same problem where the OK button in camera app did nothing, both on emulator and on nexus one.

The problem went away after specifying a safe filename that is without white spaces, without special characters, in MediaStore.EXTRA_OUTPUT Also, if you are specifying a file that resides in a directory that has not yet been created, you have to create it first. Camera app doesn't do mkdir for you.

You could use:

echo date('F Y', strtotime('20130814'));

which should do the trick.

Edit: You have a date which is in a string format. To be able to format it nicelt, you first need to change it into a date itself - which is where strtotime comes in. It is a fantastic feature that converts almost any plausible expression of a date into a date itself. Then we can actually use the date() function to format the output into what you want.

An example how to avoid null e.g. use filter before groupingBy

Filter out the null instances before groupingBy.

MyObjectlist.stream()
            .filter(p -> p.getSomeInstance() != null)
            .collect(Collectors.groupingBy(MyObject::getSomeInstance));

There's a fmod function too, that can be used : fmod($my_var, 1) will return the same result, but sometime with a small round error.

Here is my simple solution:

1 - Define your fragment

public class MyFragment extends Fragment {

    private String parameter;

    public MyFragment() {
    }

    public void setParameter(String parameter) {
        this.parameter = parameter;
    } 
}

2 - Create your new fragment and populate the parameter

    myfragment = new MyFragment();
    myfragment.setParameter("here the value of my parameter");

3 - Enjoy it!

Obviously you can change the type and the number of parameters. Quick and easy.

Another option - to convert to C++ besides Shed Skin - is Pythran.

To quote High Performance Python by Micha Gorelick and Ian Ozsvald:

Pythran is a Python-to-C++ compiler for a subset of Python that includes partial numpy support. It acts a little like Numba and Cython—you annotate a function’s arguments, and then it takes over with further type annotation and code specialization. It takes advantage of vectorization possibilities and of OpenMP-based parallelization possibilities. It runs using Python 2.7 only.

One very interesting feature of Pythran is that it will attempt to automatically spot parallelization opportunities (e.g., if you’re using a map), and turn this into parallel code without requiring extra effort from you. You can also specify parallel sections using pragma omp > directives; in this respect, it feels very similar to Cython’s OpenMP support.

Behind the scenes, Pythran will take both normal Python and numpy code and attempt to aggressively compile them into very fast C++—even faster than the results of Cython.

You should note that this project is young, and you may encounter bugs; you should also note that the development team are very friendly and tend to fix bugs in a matter of hours.

string s = "" + 2;

and you can do nice things like:

string s = 2 + 2 + "you" 

The result will be:

"4 you"

Don't quote the column filename

mysql> INSERT INTO risks (status, subject, reference_id, location, category, team,    technology, owner, manager, assessment, notes,filename) 
VALUES ('san', 'ss', 1, 1, 1, 1, 2, 1, 1, 'sment', 'notes','santu');

You probably need to change your mount command from:

[root@localhost Desktop]# sudo mount -t vboxsf D:\share_folder_vm \share_folder

to:

[root@localhost Desktop]# sudo mount -t vboxsf share_name \share_folder

where share_name is the "Name" of the share in the VirtualBox -> Shared Folders -> Folder List list box. The argument you have ("D:\share_folder_vm") is the "Path" of the share on the host, not the "Name".

Try this:

import time
while True:
    print("Hi ", end="\r")
    time.sleep(1)
    print("Bob", end="\r")
    time.sleep(1)

It worked for me. The end="\r" part is making it overwrite the previous line.

WARNING!

If you print out hi, then print out hello using \r, you’ll get hillo because the output wrote over the previous two letters. If you print out hi with spaces (which don’t show up here), then it will output hi. To fix this, print out spaces using \r.

You could just go ahead and try :

    Console.WriteLine("1. Add account.");
    Console.WriteLine("Enter choice: ");
    int choice=int.Parse(Console.ReadLine());

That should work for the case statement.

It works with the switch statement and doesn't throw an exception.

Taking the answer from @jack-allan I modified the function slightly to allow ES6 default properties such as:

function( a, b = 1, c ){};

to still return [ 'a', 'b' ]

/**
 * Get the keys of the paramaters of a function.
 *
 * @param {function} method  Function to get parameter keys for
 * @return {array}
 */
var STRIP_COMMENTS = /((\/\/.*$)|(\/\*[\s\S]*?\*\/))/mg;
var ARGUMENT_NAMES = /(?:^|,)\s*([^\s,=]+)/g;
function getFunctionParameters ( func ) {
    var fnStr = func.toString().replace(STRIP_COMMENTS, '');
    var argsList = fnStr.slice(fnStr.indexOf('(')+1, fnStr.indexOf(')'));
    var result = argsList.match( ARGUMENT_NAMES );

    if(result === null) {
        return [];
    }
    else {
        var stripped = [];
        for ( var i = 0; i < result.length; i++  ) {
            stripped.push( result[i].replace(/[\s,]/g, '') );
        }
        return stripped;
    }
}

android.os.Process.killProcess(android.os.Process.myPid()); works fine, but it is recommended to let the Android platform worry about the memory management:-)

You don't have to register an actual BroadcastReceiver as Android's BatteryManager is using a sticky Intent:

IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = registerReceiver(null, ifilter);

int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);

float batteryPct = level / (float)scale;

return (int)(batteryPct*100);

This is from the official docs over at https://developer.android.com/training/monitoring-device-state/battery-monitoring.html.

For simple objects, I like this method:

class Person {
  constructor(
    public id: String, 
    public name: String, 
    public title: String) {};

  static deserialize(input:any): Person {
    return new Person(input.id, input.name, input.title);
  }
}

var person = Person.deserialize({id: 'P123', name: 'Bob', title: 'Mr'});

Leveraging the ability to define properties in the constructor lets it be concise.

This gets you a typed object (vs all the answers that use Object.assign or some variant, which give you an Object) and doesn't require external libraries or decorators.

The my.cnf file you should edit is the /etc/mysql/my.cnf file. Just:

sudo nano /etc/mysql/my.cnf

Then add:

[mysqld]
local-infile 

[mysql]
local-infile 

The headers [mysqld] and [mysql] are already given, just locate them in the file and add local-infile underneath each of them.

It works for me on MySQL 5.5 on Ubuntu 12.04 LTS.

You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:

if (dsnt<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
  t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)       
} 

To put it more simply, if you have:

if(condition == TRUE) x <- TRUE
else x <- FALSE

Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:

if(condition == TRUE) {x <- TRUE
 } else {x <- FALSE}

I don't commit this file in my projects. What's the point ?

1. It's generated
2. It's the cause of a SHA1 code integrity err in gitlab with gitlab-ci.yml builds

Though it's true that I never use ^ in my package.json for libs because I had bad experiences with it.

\n is for unix
\r is for mac (before OS X)
\r\n is for windows format

you can also take System.getProperty("line.separator")

it will give you the appropriate to your OS

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

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

df.your_column_name.mean()

As of PHP 7.3, array_key_last is available

$lastEl = $myArray[array_key_last($myArray)];

you don’t need a select … from dual, just write:

SELECT t.*, dbms_random.value(1,9) RandomNumber
  FROM myTable t

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">
  <div class="row justify-content-center align-items-center">
    <h1>Form</h1>    
  </div>
  <hr/>
  <div class="row justify-content-center align-items-center h-100">
    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>
        <div class="form-group text-center">
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 1
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 2
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio" disabled>Option 3
  </label>
          </div>
        </div>
        <div class="form-group">
          <div class="container">
            <div class="row">
              <div class="col"><button class="col-6 btn btn-secondary btn-sm float-left">Reset</button></div>
              <div class="col"><button class="col-6 btn btn-primary btn-sm float-right">Submit</button></div>
            </div>
          </div>
        </div>

      </form>
    </div>
  </div>
</div>

I hope this helps someone. Thank you.

This is a classic question, with two solutions. If you want to remove exactly one comma, which may or may not be there, use:

if (substr($string, -1, 1) == ',')
{
  $string = substr($string, 0, -1);
}

If you want to remove all commas from the end of a line use the simpler:

$string = rtrim($string, ',');

The rtrim function (and corresponding ltrim for left trim) is very useful as you can specify a range of characters to remove, i.e. to remove commas and trailing whitespace you would write:

$string = rtrim($string, ", \t\n");

Static Variables Can only be accessed only in static methods, so when we declare the static variables those getter and setter methods will be static methods

static methods is a class level we can access using class name

The following is example for Static Variables Getters And Setters:

public class Static 
{

    private static String owner;
    private static int rent;
    private String car;
    public String getCar() {
        return car;
    }
    public void setCar(String car) {
        this.car = car;
    }
    public static int getRent() {
        return rent;
    }
    public static void setRent(int rent) {
        Static.rent = rent;
    }
    public static String getOwner() {
        return owner;
    }

    public static void setOwner(String owner) {
        Static.owner = owner;
    }

}

If you are using post as a model (without dependency injection), you can also do:

$posts = Post::orderBy('id', 'DESC')->get();

Bootstrap versions before 4 and 5 do not define ml, mr, pl, and pr.

Bootstrap versions 4 and 5 define the classes of ml, mr, pl, and pr.

For example:

mr--1
ml--1
pr--1
pl--1

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

When you use Java for Android development, it is recommended to use SparseIntArray to prevent autoboxing between int and Integer.

You can finde more information to SparseIntArray in the Android Developers documentation and a good explanation for autoboxing on Android enter link description here

You can use the option -C (or --directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist:

mkdir foo
tar -xzf bar.tar.gz -C foo

If you are not using a tar capable of extracting to a specific directory, you can simply cd into your target directory prior to calling tar; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:

mkdir foo
(cd foo; tar -xzf ../bar.tar.gz)  # instead of ../ you can use an absolute path as well

Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:

TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz

One method would be to run multiple instances of node.js on the server and then put a load balancer (preferably a non-blocking one like nginx) in front of them.

No, you cannot put an assignment inside a lambda because of its own definition. If you work using functional programming, then you must assume that your values are not mutable.

One solution would be the following code:

output = lambda l, name: [] if l==[] \
             else [ l[ 0 ] ] + output( l[1:], name ) if l[ 0 ].name == name \
             else output( l[1:], name ) if l[ 0 ].name == "" \
             else [ l[ 0 ] ] + output( l[1:], name )

I know it is an old question now, but for users who are using Maven plugin with Eclipse under Windows, you have two options:

1. If you got Maven installed as a standalone application:

   You can use the following command in the CMD under your project path:

   mvn eclipse:eclipse
   

   It will update your repository with all the missing jars, according to your dependencies in your pom.xml file.

2. If you haven't got Maven installed as a standalone application you can follow these steps on your eclipse:

   Right click on the project ->Run As -- >Run configurations.

   Then select mavenBuild.

   Then click new button to create a configuration of the selected type .Click on Browse workspace then select your project and in goals specify eclipse:eclipse

You can refer to how to run the command mvn eclipse:eclipse for further details.

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.

The environment variable solution doesn't work for me running tensorflow 2.3.1. I assume by the comments in the github thread that the below solution works for versions >=2.1.0.

From tensorflow github:

import tensorflow as tf

# Hide GPU from visible devices
tf.config.set_visible_devices([], 'GPU')

Make sure to do this right after the import with fresh tensorflow instance (if you're running jupyter notebook, restart the kernel).

And to check that you're indeed running on the CPU:

# To find out which devices your operations and tensors are assigned to
tf.debugging.set_log_device_placement(True)

# Create some tensors and perform an operation
a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
c = tf.matmul(a, b)

print(c)

Expected output:

2.3.1
Executing op MatMul in device /job:localhost/replica:0/task:0/device:CPU:0
tf.Tensor(
[[22. 28.]
 [49. 64.]], shape=(2, 2), dtype=float32)

1) Put https://api-server.com/API/index.php/member/signin in the url input box and choose POST from the dropdown

2) In Headers tab, enter:

Content-Type: image/jpeg

Content-Transfer-Encoding: binary

3) In Body tab, select the raw radio button and write:

{"description":"","phone":"","lastname":"","app_version":"2.6.2","firstname":"","password":"my_pass","city":"","apikey":"213","lang":"fr","platform":"1","email":"[email protected]","pseudo":"example"}

select form-data radio button and write:

key = name Value = userfile Select Text key = filename Select File and upload your profil.jpg

Don't render 404 yourself, there's no reason to; Rails has this functionality built in already. If you want to show a 404 page, create a render_404 method (or not_found as I called it) in ApplicationController like this:

def not_found
  raise ActionController::RoutingError.new('Not Found')
end

Rails also handles AbstractController::ActionNotFound, and ActiveRecord::RecordNotFound the same way.

This does two things better:

1) It uses Rails' built in rescue_from handler to render the 404 page, and 2) it interrupts the execution of your code, letting you do nice things like:

  user = User.find_by_email(params[:email]) or not_found
  user.do_something!

without having to write ugly conditional statements.

As a bonus, it's also super easy to handle in tests. For example, in an rspec integration test:

# RSpec 1

lambda {
  visit '/something/you/want/to/404'
}.should raise_error(ActionController::RoutingError)

# RSpec 2+

expect {
  get '/something/you/want/to/404'
}.to raise_error(ActionController::RoutingError)

And minitest:

assert_raises(ActionController::RoutingError) do 
  get '/something/you/want/to/404'
end

OR refer more info from Rails render 404 not found from a controller action

You should only need to do a single join:

SELECT e.Grade, v.Score, e.CaseNum, e.FileNum, e.ActivityNum
FROM Evaluation e
INNER JOIN Value v ON e.CaseNum = v.CaseNum AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum

ES6 :

Use Array.from (docs here):

console.log(
   Array.from({length:5},(v,k)=>k+1)
)

@Url.Action("Survey", "Applications", new { applicationid = @Model.ApplicationID }, protocol: Request.Url.Scheme)

I did want to add one more answer that utilizes a VBA function, but it does get the job done in one SQL statement. Though, it can be slow.

UPDATE FUNCTIONS
SET FUNCTIONS.Func_TaxRef = DLookUp("MinOfTax_Code", "SELECT
FUNCTIONS.Func_ID,Min(TAX.Tax_Code) AS MinOfTax_Code
FROM TAX, FUNCTIONS
WHERE (((FUNCTIONS.Func_Pure)<=[Tax_ToPrice]) AND ((FUNCTIONS.Func_Year)=[Tax_Year]))
GROUP BY FUNCTIONS.Func_ID;", "FUNCTIONS.Func_ID=" & Func_ID)

Just in case, if anyone wants to save a dynamic zip file through SaveFileDialog.

        var logFileName = "zip_filename.zip";
        appLogSaver.FileName = logFileName;
        appLogSaver.Filter = "LogFiles|*.zip";
        appLogSaver.DefaultExt = "zip";
        DialogResult resDialog = appLogSaver.ShowDialog();

        if (resDialog.ToString() == "OK")
        {
            System.IO.FileStream fs = (System.IO.FileStream)appLogSaver.OpenFile();

            using (var memoryStream = new MemoryStream())
            {
                using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
                {
                    var demoFile = archive.CreateEntry("foo.txt");
                    using (var entryStream = demoFile.Open())
                    {
                        using (var streamWriter = new StreamWriter(entryStream))
                        {
                            //read your existing file and put the content here 
                            streamWriter.Write("Bar!");
                        }
                    }

                    var demoFile2 = archive.CreateEntry("foo2.txt");
                    using (var entryStream = demoFile2.Open())
                    {
                        using (var streamWriter = new StreamWriter(entryStream))
                        {
                            streamWriter.Write("Bar2!");
                        }
                    }
                }

                memoryStream.Seek(0, SeekOrigin.Begin);
                memoryStream.CopyTo(fs);
            }
            fs.Close();
        }

round(number, 1)

Here is my 3 cents ...
This demonstrates explicit json serialization for a tree-like python object.
Note: If you actually wanted some code like this you could use the twisted FilePath class.

import json, sys, os

class File:
    def __init__(self, path):
        self.path = path

    def isdir(self):
        return os.path.isdir(self.path)

    def isfile(self):
        return os.path.isfile(self.path)

    def children(self):        
        return [File(os.path.join(self.path, f)) 
                for f in os.listdir(self.path)]

    def getsize(self):        
        return os.path.getsize(self.path)

    def getModificationTime(self):
        return os.path.getmtime(self.path)

def _default(o):
    d = {}
    d['path'] = o.path
    d['isFile'] = o.isfile()
    d['isDir'] = o.isdir()
    d['mtime'] = int(o.getModificationTime())
    d['size'] = o.getsize() if o.isfile() else 0
    if o.isdir(): d['children'] = o.children()
    return d

folder = os.path.abspath('.')
json.dump(File(folder), sys.stdout, default=_default)

You can solve this by using explicit wait so that you don't have to use hard wait.

If you fetching all the elements with one property and iterating through it using for each loop you can use wait inside the loop like this,

List<WebElement> elements = driver.findElements("Object property");
for(WebElement element:elements)
{
    new WebDriverWait(driver,10).until(ExpectedConditions.presenceOfAllElementsLocatedBy("Object property"));
    element.click();//or any other action
}

or for single element you can use below code,

new WebDriverWait(driver,10).until(ExpectedConditions.presenceOfAllElementsLocatedBy("Your object property"));
driver.findElement("Your object property").click();//or anyother action 

UPDATE:

Time has changed, you can now remove (expire) TestFlight Builds as in this answer but you still cannot delete the build.

OLD:

I asked apple and here is their answer:

I understand you would like to remove a build from iTunes Connect as shown in your screenshot.

Please be advised this is expected behavior as you can remove a build from being the current build but you cannot delete it from iTunes Connect. For more information, please refer to the iTunes Connect Developer Guide: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/

So i just can't.

The problem is in the () you have to go []

if (isset($_POST('sms_code') == TRUE)

by

if (isset($_POST['sms_code'] == TRUE)

Your question is not very clear but this should achieve what you are trying to do:

decimal numericValue = 3494309432324.00m;
string formatted = numericValue.ToString("#,##0.00");

Then formatted will contain: 3,494,309,432,324.00

None of these answers worked for me.

Instead, I had to use the Call command:

Call "\\Path To Program\Program.exe" <parameters>

I'm not sure this actually waits for completion... the C++ Redistributable I was installing went fast enough that it didn't matter

See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

http://developers.facebook.com/docs/opengraph/using-app-tokens/

"An App Access Token does not expire unless you refresh the application secret through your app settings."

The body-parser module only handles JSON and urlencoded form submissions, not multipart (which would be the case if you're uploading files).

For multipart, you'd need to use something like connect-busboy or multer or connect-multiparty (multiparty/formidable is what was originally used in the express bodyParser middleware). Also FWIW, I'm working on an even higher level layer on top of busboy called reformed. It comes with an Express middleware and can also be used separately.

To add spacing between entries in a legend, adjust the margins of the theme element legend.text.

To add 30pt of space to the right of each legend label (may be useful for a horizontal legend):

p + theme(legend.text = element_text(
    margin = margin(r = 30, unit = "pt")))

To add 30pt of space to the left of each legend label (may be useful for a vertical legend):

p + theme(legend.text = element_text(
    margin = margin(l = 30, unit = "pt")))

for a ggplot2 object p. The keywords are legend.text and margin.

[Note about edit: When this answer was first posted, there was a bug. The bug has now been fixed]

You can use apache commons IOUtils to iterate through the line and append each line to StringBuilder. And don't forget to close the InputStream

StringBuilder sb = new StringBuilder();
FileInputStream fin=new FileInputStream("textfile.txt");
LineIterator lt=IOUtils.lineIterator(fin, "utf-8");
while(lt.hasNext())
{
  sb.append(lt.nextLine());
}
String text = sb.toString();
IOUtils.closeQuitely(fin);

Run a test.

   string coerce:          7.42296099663

   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

// -----------------
print "\n";
print "string coerce:          ".$string_coerce->Elapsed()."\n";
print "string cast:            ".$string_cast->Elapsed()."\n";
print "string fail coerce:     ".$string_coerce_fail->Elapsed()."\n";
print "string fail cast:       ".$string_cast_fail->Elapsed()."\n";


class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    function Timer() {
        $this->ticking = null;
    }

    function Start() {
        $this->ticking = true;
        $this->started_at = microtime(TRUE);
    }

    function Stop() {
        if( $this->ticking )
            $this->elapsed = microtime(TRUE) - $this->started_at;
        $this->ticking = false;
    }

    function Elapsed() {
        switch( $this->ticking ) {
            case true: return "Still Running";
            case false: return $this->elapsed;
            case null: return "Not Started";
        }
    }
}

map() doesn't return a list, it returns a map object.

You need to call list(map) if you want it to be a list again.

Even better,

from itertools import imap
payIntList = list(imap(int, payList))

Won't take up a bunch of memory creating an intermediate object, it will just pass the ints out as it creates them.

Also, you can do if choice.lower() == 'n': so you don't have to do it twice.

Python supports +=: you can do payIntList[i] += 1000 and numElements += 1 if you want.

If you really want to be tricky:

from itertools import count
for numElements in count(1):
    payList.append(raw_input("Enter the pay amount: "))
    if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
         break

and / or

for payInt in payIntList:
    payInt += 1000
    print payInt

Also, four spaces is the standard indent amount in Python.

jQuery.scrollTo will do everything you want and more!

You can pass it all kinds of different things:

• A raw number
• A string('44', '100px', '+=30px', etc )
• A DOM element (logically, child of the scrollable element)
• A selector, that will be relative to the scrollable element
• The string 'max' to scroll to the end.
• A string specifying a percentage to scroll to that part of the container (f.e: 50% goes to * to the middle).
• A hash { top:x, left:y }, x and y can be any kind of number/string like above.

Image shown below. I'm only typing this because of a 30 character minimum imposed by Stackoverflow.

This is not as complicated as some of the other answers make it.

Pin the left and top edges

Just use auto layout to add constraints to pin the left and top sides of the label.

After that it will automatically resize.

Notes

• Don't add constraints for the width and height. Labels have an intrinsic size based on their text content.
• Thanks to this answer for help with this.

• No need to set sizeToFit when using auto layout. My complete code for the example project is here:

  import UIKit
  class ViewController: UIViewController {
  
      @IBOutlet weak var myLabel: UILabel!
  
      @IBAction func changeTextButtonTapped(sender: UIButton) {
          myLabel.text = "my name is really long i want it to fit in this box"
      }
  }
  

• If you want your label to line wrap then set the number of lines to 0 in IB and add myLabel.preferredMaxLayoutWidth = 150 // or whatever in code. (I also pinned my button to the bottom of the label so that it would move down when the label height increased.)

• If you are looking for dynamically sizing labels inside a UITableViewCell then see this answer.

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

if You are Using Toolbar the just Add

android:layout_gravity="center_horizontal"

Under the Toolbar Just like this snippet

 <android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"    //Important 
            android:textColor="@color/whitecolor"
            android:textSize="20sp"
            android:textStyle="bold" />
    </android.support.v7.widget.Toolbar>

</android.support.design.widget.AppBarLayout>

We actually have some notification code in our product that uses TLS to send mail if it is available.

You will need to set the Java Mail properties. You only need the TLS one but you might need SSL if your SMTP server uses SSL.

Properties props = new Properties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");  // If you need to authenticate
// Use the following if you need SSL
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

You can then either pass this to a JavaMail Session or any other session instantiator like Session.getDefaultInstance(props).

I have this same requirement - we want to put logs in a specific root directory that should exist within the environment.

public static readonly string DefaultLogFilePath = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

If I want to combine this with a sub-directory, I should be able to use Path.Combine( ... ).

The GetFolderPath method has an overload for special folder options which allows you to control whether the specified path be created or simply verified.

Find the file "config.inc.php" under your phpMyAdmin directory and edit the following lines:

$cfg['Servers'][$i]['auth_type'] = 'config'; // config, http, cookie

$cfg['Servers'][$i]['user'] = 'root'; // MySQL user

$cfg['Servers'][$i]['password'] = 'TYPE_YOUR_PASSWORD_HERE'; // MySQL password

Note that the password used in the 'password' field must be the same for the MySQL root password. Also, you should check if root login is allowed in this line:

$cfg['Servers'][$i]['AllowRoot']     = TRUE;        // true = allow root login

This way you have your root password set.

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

I tried with the following and it's worked:

release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

SELECT column_name, COUNT(column_name)
FROM table_name
GROUP BY column_name

Well, if you are writing to a CSV file, then why do you use space as a delimiter? CSV files use commas or semicolons (in Excel) as cell delimiters, so if you use delimiter=' ', you are not really producing a CSV file. You should simply construct csv.writer with the default delimiter and dialect. If you want to read the CSV file later into Excel, you could specify the Excel dialect explicitly just to make your intention clear (although this dialect is the default anyway):

example = csv.writer(open("test.csv", "wb"), dialect="excel")

Try:

import itertools as it
''.join(el[0] for el in it.takewhile(lambda t: t[0] == t[1], zip(string1, string2)))

It does the comparison from the beginning of both strings.

Maybe because other languages do this as well, so it is generally-accepted behavior. (For good reasons, as shown in the other answers)

I have the same issue with primeNg DataTable. After trying and crying, I've fixed the issue by using this code.

private deepArrayCopy(arr: SelectItem[]): SelectItem[] {
    const result: SelectItem[] = [];
    if (!arr) {
      return result;
    }
    const arrayLength = arr.length;
    for (let i = 0; i <= arrayLength; i++) {
      const item = arr[i];
      if (item) {
        result.push({ label: item.label, value: item.value });
      }
    }
    return result;
  }

For initializing backup value

backupData = this.deepArrayCopy(genericItems);

For resetting changes

genericItems = this.deepArrayCopy(backupData);

The magic bullet is to recreate items by using {} instead of calling constructor. I've tried new SelectItem(item.label, item.value) which doesn't work.

Copy into a column, select that column and HOME > Editing > Find & Select, Replace:

Replace All.

There is a space after the asterisk.

Try this

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.merge.html

left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns

right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs

As defined in App_start.BundleConfig, it's just calling

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

Nothing happens even if you remove that section.

I successfully use the following method in one file,

But come up with exactly the same error again... Only the last line come up with error

Newpath = Mid(ThisWorkbook.FullName, 1, _
 Len(ThisWorkbook.FullName) - Len(ThisWorkbook.Name)) & "\" & "ABC - " & Format(Date, "dd-mm-yyyy") & ".xlsm"
ThisWorkbook.SaveAs (Newpath)

Try using "/" instead of "\" for the path to your image. Some comments here seem to come from people that do not understand some of us are simply learning web development which in many cases is best done locally. So instead of using src=C:\Pics\H.gif use src="C:/Pics/H.gif" for an absolute path or just src="Pics/H.gif" for a relative path if your Pics are in a sub-directory of your html page's location). Note also, it is good practice to surround your path with quotes. otherwise you will have problems with paths that include spaces and other odd characters.

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

I am using a handler and runnable to create a timer. I wrapper this in an abstract class. Just derive/implement it and you are good to go:

 public static abstract class SimpleTimer {
    abstract void onTimer();

    private Runnable runnableCode = null;
    private Handler handler = new Handler();

    void startDelayed(final int intervalMS, int delayMS) {
        runnableCode = new Runnable() {
            @Override
            public void run() {
                handler.postDelayed(runnableCode, intervalMS);
                onTimer();
            }
        };
        handler.postDelayed(runnableCode, delayMS);
    }

    void start(final int intervalMS) {
        startDelayed(intervalMS, 0);
    }

    void stop() {
        handler.removeCallbacks(runnableCode);
    }
}

Note that the handler.postDelayed is called before the code to be executed - this will make the timer more closed timed as "expected". However in cases were the timer runs to frequently and the task (onTimer()) is long - there might be overlaps. If you want to start counting intervalMS after the task is done, move the onTimer() call a line above.

If you don't like the idea of "reverting a revert" (especially when that means losing history information for many commits), you can always head to the git documentation about "Reverting a faulty merge".

Given the following starting situation

 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E   <-- fixed-up topic branch

(W is your initial revert of the merge M; D and E are fixes to your initially broken feature branch/commit)

You can now simply replay commits A to E, so that none of them "belongs" to the reverted merge:

$ git checkout E
$ git rebase --no-ff P

The new copy of your branch can now be merged to master again:

   A'---B'---C'------------D'---E'  <-- recreated topic branch
  /
 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E

You can do it using clone() function of jQuery, Accepted answer is ok but i am providing alternative to it, you can use append(), but it works only if you can change html slightly as below:

The size_t type is meant to specify the size of something so it's natural to use it, for example, getting the length of a string and then processing each character:

for (size_t i = 0, max = strlen (str); i < max; i++)
    doSomethingWith (str[i]);

You do have to watch out for boundary conditions of course, since it's an unsigned type. The boundary at the top end is not usually that important since the maximum is usually large (though it is possible to get there). Most people just use an int for that sort of thing because they rarely have structures or arrays that get big enough to exceed the capacity of that int.

But watch out for things like:

for (size_t i = strlen (str) - 1; i >= 0; i--)

which will cause an infinite loop due to the wrapping behaviour of unsigned values (although I've seen compilers warn against this). This can also be alleviated by the (slightly harder to understand but at least immune to wrapping problems):

for (size_t i = strlen (str); i-- > 0; )

By shifting the decrement into a post-check side-effect of the continuation condition, this does the check for continuation on the value before decrement, but still uses the decremented value inside the loop (which is why the loop runs from len .. 1 rather than len-1 .. 0).

Pointing to Best Practices for Using Strings in the .NET Framework:

• Use StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for comparisons as your safe default for culture-agnostic string matching.
• Use comparisons with StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for better performance.
• Use the non-linguistic StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase values instead of string operations based on CultureInfo.InvariantCulture when the comparison is linguistically irrelevant (symbolic, for example).

And finally:

• Do not use string operations based on StringComparison.InvariantCulture in most cases. One of the few exceptions is when you are persisting linguistically meaningful but culturally agnostic data.

' Create The Object
Set FSO = CreateObject("Scripting.FileSystemObject")

' How To Write To A File
Set File = FSO.CreateTextFile("C:\foo\bar.txt",True)
File.Write "Example String"
File.Close

' How To Read From A File
Set File = FSO.OpenTextFile("C:\foo\bar.txt")
Do Until File.AtEndOfStream
    Line = File.ReadLine
    WScript.Echo(Line)
Loop
File.Close

' Another Method For Reading From A File
Set File = FSO.OpenTextFile("C:\foo\bar.txt")
Set Text = File.ReadAll
WScript.Echo(Text)
File.Close

This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.

You'll have to use the "userInfo" variant and pass a NSDictionary object that contains the messageTotal integer:

NSDictionary* userInfo = @{@"total": @(messageTotal)};

NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:@"eRXReceived" object:self userInfo:userInfo];

On the receiving end you can access the userInfo dictionary as follows:

-(void) receiveTestNotification:(NSNotification*)notification
{
    if ([notification.name isEqualToString:@"TestNotification"])
    {
        NSDictionary* userInfo = notification.userInfo;
        NSNumber* total = (NSNumber*)userInfo[@"total"];
        NSLog (@"Successfully received test notification! %i", total.intValue);
    }
}

I found myself in a similar predicament today while trying to run a command through a Node.js module:

I was using the PowerShell and trying to run:

command -e 'func($a)'

But with the extra symbols, PowerShell was mangling the arguments. To fix, I back-tick escaped double-quote marks:

command -e `"func($a)`"

Instead of casting to float you can do following

def mean(nums):
    return sum(nums, 0.0) / len(nums)

or using lambda

mean = lambda nums: sum(nums, 0.0) / len(nums)

UPDATES: 2019-12-15

Python 3.8 added function fmean to statistics module. Which is faster and always returns float.

Convert data to floats and compute the arithmetic mean.

This runs faster than the mean() function and it always returns a float. The data may be a sequence or iterable. If the input dataset is empty, raises a StatisticsError.

fmean([3.5, 4.0, 5.25])

4.25

New in version 3.8.

I guess it depends on what you want. For simple objects, I guess you could use the second methods. When your objects grow larger and you're planning on using similar objects, I guess the first method would be better. That way you can also extend it using prototypes.

Example:

function Circle(radius) {
    this.radius = radius;
}
Circle.prototype.getCircumference = function() {
    return Math.PI * 2 * this.radius;
};
Circle.prototype.getArea = function() {
    return Math.PI * this.radius * this.radius;
}

I am not a big fan of the third method, but it's really useful for dynamically editing properties, for example var foo='bar'; var bar = someObject[foo];.

The following is the one that I'm using to generate a vertical gradient from completely opaque (top) to 20% in transparency (bottom) for the same color:

background: linear-gradient(to bottom, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
background: -o-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* Opera 11.10+ */
background: -moz-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* Chrome10-25,Safari5.1-6 */
background: -ms-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* IE10+ */
-ms-filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE 5.5 - 9 */

With BeautifulStoneSoup gone in bs4, it's even simpler in Python3

from bs4 import BeautifulSoup

soup = BeautifulSoup(html)
text = soup.get_text()
print(text)

Yea, java is Garbage collected, it will delete the memory for you.

Does this help you:

<script type="text/javascript">
window.onerror = function() {
    alert("Error caught");
};

xxx();

I'm not sure how it handles Flash errors though...

Update: it doesn't work in Opera, but I'm hacking Dragonfly right now to see what it gets. Suggestion about hacking Dragonfly came from this question:

If you take advantage of how == works, you could simply create an object with a custom toString (or valueOf) function that changes what it returns each time it is used such that it satisfies all three conditions.

const a = {_x000D_
  i: 1,_x000D_
  toString: function () {_x000D_
    return a.i++;_x000D_
  }_x000D_
}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
  console.log('Hello World!');_x000D_
}

The reason this works is due to the use of the loose equality operator. When using loose equality, if one of the operands is of a different type than the other, the engine will attempt to convert one to the other. In the case of an object on the left and a number on the right, it will attempt to convert the object to a number by first calling valueOf if it is callable, and failing that, it will call toString. I used toString in this case simply because it's what came to mind, valueOf would make more sense. If I instead returned a string from toString, the engine would have then attempted to convert the string to a number giving us the same end result, though with a slightly longer path.

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/

Either you can use the accessors provided by the Web Storage API or you could write a wrapper/adapter. From your stated issue with defineGetter/defineSetter is sounds like writing a wrapper/adapter is too much work for you.

I honestly don't know what to tell you. Maybe you could reevaluate your opinion of what is a "ridiculous limitation". The Web Storage API is just what it's supposed to be, a key/value store.

it's very strange that I met this problem because I forgot specify the 'type' parameter. e.g.:

add_column :cms_push_msgs, :android_title

which should be:

add_column :cms_push_msgs, :android_content, :string 

There's also the bash builtin 'expr' command:

INPUT="someletters_12345_moreleters.ext"  
SUBSTRING=`expr match "$INPUT" '.*_\([[:digit:]]*\)_.*' `  
echo $SUBSTRING

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

I recommend to use both, prop and attr because I had problems with Chrome and I solved it using both functions.

if ($(':checkbox').is(':checked')){
    $(':checkbox').prop('checked', true).attr('checked', 'checked');
}
else {
    $(':checkbox').prop('checked', false).removeAttr('checked');
}

I ran into the same situation where I wanted to align a few div elements vertically in a row and found that Bootstrap classes col-xx-xx applies style to the div as float: left.

I had to apply the style on the div elements like style="Float:none" and all my div elements started vertically aligned. Here is the working example:

<div class="col-lg-4" style="float:none;">

If you want to iterate over both keys and values of the dictionary, do this:

for key, value in data.items():
    print key, value

If by 'current directory' you mean the directory in which the zip file is, then I would use this command:

find . -name '*.zip' -execdir unzip {} \; 

excerpt from find's man page

-execdir command ;
-execdir command {} +

Like -exec, but the specified command is run from the subdirectory containing the matched file, which is not normally the directory in which you started find. This a much more secure method for invoking commands, as it avoids race conditions during resolution of the paths to the matched files. As with the -exec option, the '+' form of -execdir will build a command line to process more than one matched file, but any given invocation of command will only list files that exist in the same subdirectory. If you use this option, you must ensure that your $PATH environment variable does not reference the current directory; otherwise, an attacker can run any commands they like by leaving an appropriately-named file in a directory in which you will run -execdir.

In my opinion, using "if(value)" to judge a value whether is an empty value is not strict, because the result of "v?true:false" is false when the value of v is 0(0 is not an empty value). You can use this function:

const isEmptyValue = (value) => {
    if (value === '' || value === null || value === undefined) {
        return true
    } else {
        return false
    }
}

You are using getData() method as void.

You can not return values from void.
