For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

In addition to Jesse Glick answer, if you want to pass string parameter then use:

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

When I faced this issue, I discovered that my problem was that the files in the 'Source Account' were copied there by a 'third party' and the Owner was not the Source Account.

I had to recopy the objects to themselves in the same bucket with the --metadata-directive REPLACE

Detailed explanation in Amazon Documentation

If you are using Xcode 8.0 to 8.3.3 and swift 2.2 to 3.0

In my case need to change in URL http:// to https:// (if not working then try)

Add an App Transport Security Setting: Dictionary.
Add a NSAppTransportSecurity: Dictionary.
Add a NSExceptionDomains: Dictionary.
Add a yourdomain.com: Dictionary.  (Ex: stackoverflow.com)

Add Subkey named " NSIncludesSubdomains" as Boolean: YES
Add Subkey named " NSExceptionAllowsInsecureHTTPLoads" as Boolean: YES

I was running a job which ran a shell script in Jenkins on a Windows machine. The job was failing due to the error given below. I was able to fix the error thanks to clues in Andrejz's answer.

Solution :

1 - Install Cygwin and note the directory where it gets installed.

It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.

2 - Tell Jenkins where sh.exe is located.

Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.

That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.

You should also be able to do:

apt install sudo

sudo -i -u tomcat

Then you should be the tomcat user. It's not clear which Linux distribution you're using, but this works with Ubuntu 18.04 LTS, for example.

I meant in the template() call..

You just need to pass the results as an object. So instead of calling

var html = template(data);

do

var html = template({apidata: data});

and use {{#each apidata}} in your template code

(removed some leftover if code that crashed)

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

Previous answer didn't work for me.

But this worked perfectly. Convert Data URI to File then append to FormData

i had sometime ago the same issue. make sure that your ssh key doesn't have password and use not common user account (e.g. better to user account called jenkins or so).

check following article http://fourkitchens.com/blog/2011/09/20/trigger-jenkins-builds-pushing-github

None of the answers here removed my workspaces. But here is one solution that may work for you.

1. Open up a Visual Studio command prompt
2. Close Visual Studio first or the delete command may not delete the workspace
3. List the workspace commands -> tf /? to find the commands available to you from the version of TFS.
4. List the workspaces -> tf workspaces
5. Delete the workspace -> tf workspace YourWorkspace /delete

If you installed using apt-get in ubuntu 14.04, you will found the default password in /var/lib/jenkins/secrets/initialAdminPassword location.

Use https://updates.jenkins-ci.org/download/plugins/. Download it from this central update repository for Jenkins.

I was having the same problem, with a value like 2016-08-8, then I solved adding a zero to have two digits days, and it works. Tested in chrome, firefox, and Edge

today:function(){
   var today = new Date();
   var d = (today.getDate() < 10 ? '0' : '' )+ today.getDate();
   var m = ((today.getMonth() + 1) < 10 ? '0' :'') + (today.getMonth() + 1);
   var y = today.getFullYear();
   var x = String(y+"-"+m+"-"+d); 
   return x;
}

I find a good solution for this issue, this solution can make it work and no need to recreate Fragments.
My key point is:

1. setup ViewPager every time you delete or add Tab(Fragment).
2. Override the getItemId method, return a specific id rather than position.

I was getting the same "cannot find symbol" error when I did Build -> Make Project. I fixed this by deleting my Maven /target folder, right clicking my project module and doing Maven -> Reimport, and doing Build -> Rebuild Project. This was on IntelliJ Idea 13.1.5.

It turns out the Maven -> Reimport was key, since the problem resurfaced a few times before I finally did that.

This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.

For Jenkins 2.121.3 version, Go to Manage jenkins -> Global tool configuration -> Git installations -> Path to Git executable: C:\Program Files\Git\bin\git.exe It works!

In Jenkins, give the http URL. SSH URL shows similar error.

While you are looping in an array with each and if you want to access another array in the context of the current item you do it like this.

Here is the example data.

[
  {
    name: 'foo',
    attr: [ 'boo', 'zoo' ]
  },
  {
    name: 'bar',
    attr: [ 'far', 'zar' ]
  }
]

Here is the handlebars to get the first item in attr array.

{{#each player}}
  <p> {{this.name}} </p>

  {{#with this.attr}}
    <p> {{this.[0]}} </p>
  {{/with}}

{{/each}}

This will output

<p> foo </p>
<p> boo </p>

<p> bar </p>
<p> far </p>

As per Jenkins Documentation,

BUILD_NUMBER

is used. This number is identify how many times jenkins run this build process $BUILD_NUMBER is general syntax for it.

None of these resigning approaches were working for me, so I had to work out something else.

In my case, I had an IPA with an expired certificate. I could have rebuilt the app, but because we wanted to ensure we were distributing exactly the same version (just with a new certificate), we did not want to rebuild it.

Instead of the ways of resigning mentioned in the other answers, I turned to Xcode’s method of creating an IPA, which starts with an .xcarchive from a build.

1. I duplicated an existing .xcarchive and started replacing the contents. (I ignored the .dSYM file.)

2. I extracted the old app from the old IPA file (via unzipping; the app is the only thing in the Payload folder)

3. I moved this app into the new .xcarchive, under Products/Applications replacing the app that was there.

4. I edited Info.plist, editing

   • ApplicationProperties/ApplicationPath
   • ApplicationProperties/CFBundleIdentifier
   • ApplicationProperties/CFBundleShortVersionString
   • ApplicationProperties/CFBundleVersion
   • Name

5. I moved the .xcarchive into Xcode’s archive folder, usually /Users/xxxx/Library/Developer/Xcode/Archives.

6. In Xcode, I opened the Organiser window, picked this new archive and did a regular (in this case Enterprise) export.

The result was a good IPA that works.

I ran into this exact problem on OS X, using JDK 1.7, after upgrading to OS X v10.9 (Mavericks). The fix that worked for me was to simply reinstall the Apple version of Java, available at http://support.apple.com/kb/DL1572.

I have same issue. Error message for me is not complete. But in my case, I've added generation jar with sources. By placing this code in pom.xml:

<build> 
    <pluginManagement>
        <plugins>
            <plugin>
                <artifactId>maven-source-plugin</artifactId>
                <version>2.1.2</version>
                <executions>
                    <execution>
                        <phase>deploy</phase>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

So in deploy phase I execute source:jar goal which produces jar with sources. And deploy ends with BUILD SUCCESS

I tried /etc/profile, ~/.profile and ~/.bash_profile and none of those worked. I found that editing ~/.bashrc for the jenkins slave account did.

The Git plugin has an option (excluded region) to use regexes to determine whether to skip building based on whether files in the commit match the excluded region regex.

Unfortunately, the stock Git plugin does not have a "included region" feature at this time (1.15). However, someone posted patches on GitHub that work on Jenkins and Hudson that implement the feature you want.

It is a little work to build, but it works as advertised and has been extremely useful since one of my Git trees has multiple independent projects.

https://github.com/jenkinsci/git-plugin/pull/49

Update: The Git plugin (1.16) now has the 'included' region feature.

As chmullig wrote, use Jenkins. Some additional points:

• In fact, arguably it was Oracle who did the forking! And technically, too, that's kinda what happened.

• It's interesting to see what comes out of "Hudson" though. While the "Winston summarizes the state and rosy future of the Hudson project" stuff they posted on the (new) Hudson website originally seemed like odd humour to me, perhaps this was a purposeful takeover, and the Sonatype guys actually have some big ideas up their sleeve. This analysis, suggesting a deliberate strategy by Oracle/Sonatype to oust Kohsuke and crew to create a more "enterprisy" Hudson is a very interesting read!

• In any case, this brief comparison a fortnight after the split—while not exactly scientific—shows Jenkins to be by far more active of the two projects.

...and a little background info:

The creator of Hudson, Kohsuke Kawaguchi, started the project on his free time, even if he was working for Sun Microsystems and later paid by them to develop it further. As @erickson noted at another SO question,

[Hudson/Jenkins] is the product of a single genius intellect—Kohsuke Kawaguchi. Because of that, it's consistent, coherent, and rock solid.

After the acquisition by Oracle, Kohsuke didn't hang around for long (^{due to lack of monitors...? ;-]}), and went to work for CloudBees. What started in late 2010 as conflict over tools between the dev community and Oracle and ended in the rename/fork/split is well documented in the links chmullig provided. To me, that whole conundrum speaks, perhaps more than anything else, to Oracle's utter inability or unwillingness to sponsor an open-source project in a way that keeps all parties (Oracle, developers, users) happy. It's not in their DNA or something, as we've seen in other cases too.

Given all of the above, I would personally follow Kohsuke and other core developers in this matter, and go with Jenkins.

I did a similar thing a few months ago, and it turned out this simple format was enough for Hudson to accept it as a test protocol:

<testsuite tests="3">
    <testcase classname="foo1" name="ASuccessfulTest"/>
    <testcase classname="foo2" name="AnotherSuccessfulTest"/>
    <testcase classname="foo3" name="AFailingTest">
        <failure type="NotEnoughFoo"> details about failure </failure>
    </testcase>
</testsuite>

Why are you grouping by? Do you mean order by?

SELECT player_name, player_salary, player_salary * 1.1 AS NewSalary
FROM players
ORDER BY player_salary, player_name;

Another easy way to clean builds is by adding the Discard Old Plugin at the end of your jobs. Set a maximum number of builds to save and then run the job again:

https://wiki.jenkins-ci.org/display/JENKINS/Discard+Old+Build+plugin

you just need to use word boundary (\b) instead of ^ and $:

\bgarp\b

I say you setup the JAVA_HOME environment variable like Pascal is saying: In Cygwin if you use bash as your shell should be:

export JAVA_HOME=/cygdrive/c/pathtothejdk

It never harms to also prepend the java bin directory path to the PATH environment variable with:

export PATH=${JAVA_HOME}/bin:${PATH}

Also add maven-enforce-plugin to make sure the right JDK is used. This is a good practice for your pom.

<build>
 <plugins>
   <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-enforcer-plugin</artifactId>
      <executions>
        <execution>
          <id>enforce-versions</id>
          <goals>
            <goal>enforce</goal>
          </goals>
          <configuration>
            <rules>
              <requireJavaVersion>
                <version>1.6</version>
              </requireJavaVersion>
            </rules>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Please, see Maven Enforcer plugin – Usage.

In my opinion, to answer this question, you need to think in terms of project life cycle and version control. In other words, does the parent pom have its own life cycle i.e. can it be released separately of the other modules or not?

If the answer is yes (and this is the case of most projects that have been mentioned in the question or in comments), then the parent pom needs his own module from a VCS and from a Maven point of view and you'll end up with something like this at the VCS level:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
`-- projectA
    |-- branches
    |-- tags
    `-- trunk
        |-- module1
        |   `-- pom.xml
        |-- moduleN
        |   `-- pom.xml
        `-- pom.xml

This makes the checkout a bit painful and a common way to deal with that is to use svn:externals. For example, add a trunks directory:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
|-- projectA
|   |-- branches
|   |-- tags
|   `-- trunk
|       |-- module1
|       |   `-- pom.xml
|       |-- moduleN
|       |   `-- pom.xml
|       `-- pom.xml
`-- trunks

With the following externals definition:

parent-pom http://host/svn/parent-pom/trunk
projectA http://host/svn/projectA/trunk

A checkout of trunks would then result in the following local structure (pattern #2):

root/
  parent-pom/
    pom.xml
  projectA/

Optionally, you can even add a pom.xml in the trunks directory:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
|-- projectA
|   |-- branches
|   |-- tags
|   `-- trunk
|       |-- module1
|       |   `-- pom.xml
|       |-- moduleN
|       |   `-- pom.xml
|       `-- pom.xml
`-- trunks
    `-- pom.xml

This pom.xml is a kind of "fake" pom: it is never released, it doesn't contain a real version since this file is never released, it only contains a list of modules. With this file, a checkout would result in this structure (pattern #3):

root/
  parent-pom/
    pom.xml
  projectA/
  pom.xml

This "hack" allows to launch of a reactor build from the root after a checkout and make things even more handy. Actually, this is how I like to setup maven projects and a VCS repository for large builds: it just works, it scales well, it gives all the flexibility you may need.

If the answer is no (back to the initial question), then I think you can live with pattern #1 (do the simplest thing that could possibly work).

Now, about the bonus questions:

• Where is the best place to define the various shared configuration as in source control, deployment directories, common plugins etc. (I'm assuming the parent but I've often been bitten by this and they've ended up in each project rather than a common one).

Honestly, I don't know how to not give a general answer here (like "use the level at which you think it makes sense to mutualize things"). And anyway, child poms can always override inherited settings.

• How do the maven-release plugin, hudson and nexus deal with how you set up your multi-projects (possibly a giant question, it's more if anyone has been caught out when by how a multi-project build has been set up)?

The setup I use works well, nothing particular to mention.

Actually, I wonder how the maven-release-plugin deals with pattern #1 (especially with the <parent> section since you can't have SNAPSHOT dependencies at release time). This sounds like a chicken or egg problem but I just can't remember if it works and was too lazy to test it.

Look at the "Sprite Text" sample in the GLSurfaceView samples.

A simple alternative is to let the C# environment increment the assembly version for you by setting the version attribute to major.minor.* (as described in the AssemblyInfo file template.)

You may be looking for a more comprehensive solution, though.

EDIT (Response to the question in a comment):

From AssemblyInfo.cs:

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]

I think you're looking for something like freopen()

I had this problem in a unit test which opened a lot of connections to the DB via a connection pool and then "stopped" the connection pool (ManagedDataSource actually) to release the connections at the end of the each test. I always ran out of connections at some point in the suite of tests.

Added a Thread.sleep(500) in the teardown() of my tests and this resolved the issue. I think that what was happening was that the connection pool stop() releases the active connections in another thread so that if the main thread keeps running tests the cleanup thread(s) got so far behind that the Oracle server ran out of connections. Adding the sleep allows the background threads to release the pooled connections.

This is much less of an issue in the real world because the DB servers are much bigger and there is a healthy mix of operations (not just endless DB connect/disconnect operations).

This is the code to create dropdown in Angular 7, 8, 9

.html file code

<div>
<label>Summary: </label>
<select (change)="SelectItem($event.target.value)" class="select">
  <option value="0">--All--</option>
  <option *ngFor="let item of items" value="{{item.Id.Value}}">
    {{item.Name}}
  </option>
</select>
</div>

.ts file code

SelectItem(filterVal: any)
{
    var id=filterVal;
    //code
}

items is an array which should be initialized in .ts file.

This is another option, using jQuery and getting only tbody rows (with the data) and desconsidering thead/tfoot.

$("#tableId > tbody > tr").length

console.log($("#myTableId > tbody > tr").length);

Try to reinstall cygwin with selected package:gcc-g++ : gnu compiler collection c++ (from devel category), openssh server and client program (net), make: the gnu version (devel), ncurses terminal (utils), enhanced vim editors (editors), an ANSI common lisp implementation (math) and libncurses-devel (lib).

This library files should be under cygwin\usr\include

Regards.

int num = Integer.parseInt("binaryString",2);

For a single boxplot:

import seaborn as sb
sb.boxplot(data=Array).set_title('Title')

For more boxplot in the same plot:

import seaborn as sb
sb.boxplot(data=ArrayofArray).set_title('Title')

e.g.

import seaborn as sb
myarray=[78.195229, 59.104538, 19.884109, 25.941648, 72.234825, 82.313911]
sb.boxplot(data=myarray).set_title('myTitle')

It has been forever in terms of the computer but this question is still unbelievably relevant! So I've taken the above answers and have combined and refined them a bit...

public interface OnKeyboardVisibilityListener {
    void onVisibilityChanged(boolean visible);
}

public final void setKeyboardListener(final OnKeyboardVisibilityListener listener) {
    final View activityRootView = ((ViewGroup) getActivity().findViewById(android.R.id.content)).getChildAt(0);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

        private boolean wasOpened;

    private final Rect r = new Rect();

        @Override
        public void onGlobalLayout() {
            activityRootView.getWindowVisibleDisplayFrame(r);

            int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
            boolean isOpen = heightDiff > 100;
            if (isOpen == wasOpened) {
                logDebug("Ignoring global layout change...");
                return;
            }

            wasOpened = isOpen;
            listener.onVisibilityChanged(isOpen);
        }
    });
}

It works for me.

It is going to write the value of your property model.Destination

This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.

Text element inside Center of SizedBox work much better way, below Sample code

Widget build(BuildContext context) {
    return RawMaterialButton(
      fillColor: Colors.green,
      splashColor: Colors.greenAccent,
      shape: new CircleBorder(),
      child: Padding(
        padding: EdgeInsets.all(10.0),
        child: Row(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            SizedBox(
              width: 100.0,
              height: 100.0,
              child: Center(
                child: Text(
                widget.buttonText,
                maxLines: 1,
                style: TextStyle(color: Colors.white)
              ),
              )
          )]
        ),
    ),
  onPressed: widget.onPressed
);
}

Enjoy coding ?

A perl oneliner would do: perl -i.bak -pe 's/[^[:ascii:]]//g' <your file>

-i says that the file is going to be edited inplace, and the backup is going to be saved with extension .bak.

Using the --mirror option seems to copy the remote tracking branches properly. However, it sets up the repository as a bare repository, so you have to turn it back into a normal repository afterwards.

git clone --mirror path/to/original path/to/dest/.git
cd path/to/dest
git config --bool core.bare false
git checkout anybranch

^{Reference: Git FAQ: How do I clone a repository with all remotely tracked branches?}

Try This, It worked like a charm! for me,

The simplest way to add backgroundColor programmatically by using ColorLiteral.

You need to add the property ColorLiteral, Xcode will prompt you with a whole list of colors in which you can choose any color. The advantage of doing this is we use lesser code, add HEX values or RGB. You will also get the recently used colors from the storyboard.

Follow steps ,

1) Add below line of code in viewDidLoad() ,

self.view.backgroundColor = ColorLiteral

and clicked on enter button .

2) Display square box next to =

3) When Clicked on Square Box Xcode will prompt you with a whole list of colors which you can choose any colors also you can set HEX values or RGB

4) You can successfully set the colors .

Hope this will help some one to set backgroundColor in different ways.

The Difference Between The Two

The main difference between a "factory method" and an "abstract factory" is that the factory method is a method, and an abstract factory is an object. I think a lot of people get these two terms confused, and start using them interchangeably. I remember that I had a hard time finding exactly what the difference was when I learnt them.

Because the factory method is just a method, it can be overridden in a subclass, hence the second half of your quote:

... the Factory Method pattern uses inheritance and relies on a subclass to handle the desired object instantiation.

The quote assumes that an object is calling its own factory method here. Therefore the only thing that could change the return value would be a subclass.

The abstract factory is an object that has multiple factory methods on it. Looking at the first half of your quote:

... with the Abstract Factory pattern, a class delegates the responsibility of object instantiation to another object via composition ...

What they're saying is that there is an object A, who wants to make a Foo object. Instead of making the Foo object itself (e.g., with a factory method), it's going to get a different object (the abstract factory) to create the Foo object.

Code Examples

To show you the difference, here is a factory method in use:

class A {
    public void doSomething() {
        Foo f = makeFoo();
        f.whatever();   
    }

    protected Foo makeFoo() {
        return new RegularFoo();
    }
}

class B extends A {
    protected Foo makeFoo() {
        //subclass is overriding the factory method 
        //to return something different
        return new SpecialFoo();
    }
}

And here is an abstract factory in use:

class A {
    private Factory factory;

    public A(Factory factory) {
        this.factory = factory;
    }

    public void doSomething() {
        //The concrete class of "f" depends on the concrete class
        //of the factory passed into the constructor. If you provide a
        //different factory, you get a different Foo object.
        Foo f = factory.makeFoo();
        f.whatever();
    }
}

interface Factory {
    Foo makeFoo();
    Bar makeBar();
    Aycufcn makeAmbiguousYetCommonlyUsedFakeClassName();
}

//need to make concrete factories that implement the "Factory" interface here

there's an interesting way to achive another goal which is to have a strongly type class base on json with a very powerfull tools that i used few days ago for first time to translate tradedoubler json result into classes

Is a simple tool: copy your json source paste and in few second you will have a strongly typed class json oriented . In this manner you will use these classes which is more powerful and simply to use.

i think it should be

select convert(varchar(10),StandardCost) +'S' from DimProduct where ProductKey = 212

or

select cast(StandardCost as varchar(10)) + 'S' from DimProduct where ProductKey = 212

If you're using HTTPS, check to make sure that your URL is correct. For example:

$ git clone https://github.com/wellle/targets.git
Cloning into 'targets'...
Username for 'https://github.com': ^C

$ git clone https://github.com/wellle/targets.vim.git
Cloning into 'targets.vim'...

Receiving objects: 100% (2182/2182), 595.77 KiB | 0 bytes/s, done.
Resolving deltas: 100% (1044/1044), done.

In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)

So, in the end your code will become like follow:

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)
    request := gorequest.New()
    titleList := []string{"title1", "title2", "title3"}
    for _, title := range titleList {
        resp, body, errs := request.Post(url).
            Set("X-Custom-Header", "myvalue").
            Send(`{"title":"` + title + `"}`).
            End()
        if errs != nil {
            fmt.Println(errs)
            os.Exit(1)
        }
        fmt.Println("response Status:", resp.Status)
        fmt.Println("response Headers:", resp.Header)
        fmt.Println("response Body:", body)
    }
}

This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

You need to somehow create a table with these values and then use NOT IN. This can be done with a temporary table, a CTE (Common Table Expression) or a Table Values Constructor (available in SQL-Server 2008):

SELECT email
FROM
    ( VALUES 
        ('email1')
      , ('email2')
      , ('email3')
    ) AS Checking (email)
WHERE email NOT IN 
      ( SELECT email 
        FROM Users
      ) 

The second result can be found with a LEFT JOIN or an EXISTS subquery:

Parameters passed to the C program executable is nothing but an array of string(or character pointer),so memory would have been already allocated for these input parameter before your program access these parameters,so no need to allocate buffer,and that way you can avoid error handling code in your program as well(Reduce chances of segfault :)).

Windows Solution:

https://sourceforge.net/projects/win32svn/

1.Download it, then add it to system path.

2.Go to work directory execute "svn clean" and "svn update" in cmd.

You can delete the latest gradle-.-all folder from the below path Windows: C:\Users\your-username.gradle\wrapper\dists

I like to describe generators, to those with a decent background in programming languages and computing, in terms of stack frames.

In many languages, there is a stack on top of which is the current stack "frame". The stack frame includes space allocated for variables local to the function including the arguments passed in to that function.

When you call a function, the current point of execution (the "program counter" or equivalent) is pushed onto the stack, and a new stack frame is created. Execution then transfers to the beginning of the function being called.

With regular functions, at some point the function returns a value, and the stack is "popped". The function's stack frame is discarded and execution resumes at the previous location.

When a function is a generator, it can return a value without the stack frame being discarded, using the yield statement. The values of local variables and the program counter within the function are preserved. This allows the generator to be resumed at a later time, with execution continuing from the yield statement, and it can execute more code and return another value.

Before Python 2.5 this was all generators did. Python 2.5 added the ability to pass values back in to the generator as well. In doing so, the passed-in value is available as an expression resulting from the yield statement which had temporarily returned control (and a value) from the generator.

The key advantage to generators is that the "state" of the function is preserved, unlike with regular functions where each time the stack frame is discarded, you lose all that "state". A secondary advantage is that some of the function call overhead (creating and deleting stack frames) is avoided, though this is a usually a minor advantage.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

If you are not familiar how to insert and retrieve into a database, go through this tutorial.

For Java 7, increment operator '++' works on Integers. Below is a tested example

    Integer i = new Integer( 12 );
    System.out.println(i); //12
    i = i++;
    System.out.println(i); //13

To render more than one whitespace on most web browsers use   instead of normal white spaces.

echo "<p>Hello &nbsp;&nbsp;&nbsp; punt"; // This will render as Hello   Punt (with 4 white spaces)
echo "<p> Hello       punt"; // This will render as Hello punt (with one space)

For showing data in raw format (with exact number of spaces and "enters") use HTML <pre> tag.

echo "<pre>Hello        punt</pre>"; //Will render exactly as written here (8 white spaces)

Or you can use some CSS to style current block, not to break text or strip spaces (I don't know, but this one)

Any way you do the output will be the same but the browser itself strips double white spaces and renders as one.

I had the same problem and I fixed it by using the

1. new context menu "Make Public".
2. Go to https://console.aws.amazon.com/s3/home,
3. select the bucket and then for each Folder or File (or multiple selects) right click and
4. "make public"

It is just Value, not @value.. Try it. I'm not sure about @Model.title, maybe it's just Model.title

for x in xrange(10):
    for y in xrange(10):
        print x*y
        if x*y > 50:
            break
    else:
        continue  # only executed if the inner loop did NOT break
    break  # only executed if the inner loop DID break

The same works for deeper loops:

for x in xrange(10):
    for y in xrange(10):
        for z in xrange(10):
            print x,y,z
            if x*y*z == 30:
                break
        else:
            continue
        break
    else:
        continue
    break

Rotating view with rotate() will not affect your view's measured size. As result, rotated view be clipped or not fit into the parent layout. This library fixes it though:

This is the simplest example I found for pagination! http://code.ciphertrick.com/2015/06/01/search-sort-and-pagination-ngrepeat-angularjs/

you need the libblas and liblapack dev packages if you are using Ubuntu.

aptitude install libblas-dev liblapack-dev
pip install scipy

The src refers directly to the font files, therefore if you place all of them on /media/fonts/roboto you should refer to them in your main.css like this: src: url('../fonts/roboto/Roboto-ThinItalic-webfont.eot');

The .. goes one folder up, which means you're referring to the media folder if the main.css is in the /media/css folder.

You have to use ../fonts/roboto/ in all url references in the CSS (and be sure that the files are in this folder and not in subdirectories, such as roboto_black_macroman).

Basically (answering to your questions):

I have css in my media/css/main.css url. So where do i need to put that folder

You can leave it there, but be sure to use src: url('../fonts/roboto/

Do i need to extract all eot,svg etc from all sub folder and put in fonts folder

If you want to refer to those files directly (without placing the subdirectories in your CSS code), then yes.

Do i need to create css file fonts.css and include in my base template file

Not necessarily, you can just include that code in your main.css. But it's a good practice to separate fonts from your customized CSS.

Here's an example of a fonts LESS/CSS file I use:

@ttf: format('truetype');

@font-face {
  font-family: 'msb';
  src: url('../font/msb.ttf') @ttf;
}
.msb {font-family: 'msb';}

@font-face {
  font-family: 'Roboto';
  src: url('../font/Roboto-Regular.ttf') @ttf;
}
.rb {font-family: 'Roboto';}
@font-face {
  font-family: 'Roboto Black';
  src: url('../font/Roboto-Black.ttf') @ttf;
}
.rbB {font-family: 'Roboto Black';}
@font-face {
  font-family: 'Roboto Light';
  src: url('../font/Roboto-Light.ttf') @ttf;
}
.rbL {font-family: 'Roboto Light';}

(In this example I'm only using the ttf) Then I use @import "fonts"; in my main.less file (less is a CSS preprocessor, it makes things like this a little bit easier)

Unless I'm mistaken, the above code does not take unallocated space into account, so if you really want to know when you'll hit a hard limit, you should use maxbytes.

I think the code below does that. It calculates free space as "freespace" + unallocated space.

select 
     free.tablespace_name,
     free.bytes,
     reserv.maxbytes,
     reserv.bytes,
     reserv.maxbytes - reserv.bytes + free.bytes "max free bytes",
     reserv.datafiles
from
    (select tablespace_name, count(1) datafiles, sum(maxbytes) maxbytes, sum(bytes) bytes from dba_data_files group by tablespace_name) reserv,
    (select tablespace_name, sum(bytes) bytes from dba_free_space group by tablespace_name) free
where free.tablespace_name = reserv.tablespace_name;

You can use:

$str = trim(str_replace("  ", " ", $str));

This removes extra whitespaces from both sides of string and converts two spaces to one within the string. Note that this won't convert three or more spaces in a row to one! Another way I can suggest is using implode and explode that is safer but totally not optimum!

$str = implode(" ", array_filter(explode(" ", $str)));

My suggestion is using a native for loop or using regex to do this kind of job.

First subtract the pivot point (cx,cy), then rotate it, then add the point again.

Untested:

POINT rotate_point(float cx,float cy,float angle,POINT p)
{
  float s = sin(angle);
  float c = cos(angle);

  // translate point back to origin:
  p.x -= cx;
  p.y -= cy;

  // rotate point
  float xnew = p.x * c - p.y * s;
  float ynew = p.x * s + p.y * c;

  // translate point back:
  p.x = xnew + cx;
  p.y = ynew + cy;
  return p;
}

Another alternative that uses an external library is _.has() from Lodash.

E.g.

_.has(a, 'b.c')

is equal to

(a && a.b && a.b.c)

EDIT: As noted in the comments, you lose out on Typescript's type inference when using this method. E.g. Assuming that one's objects are properly typed, one would get a compilation error with (a && a.b && a.b.z) if z is not defined as a field of object b. But using _.has(a, 'b.z'), one would not get that error.

I asked the same question some time ago and had to answer it myself. Here's what I came up with:

It seems, my first thought [that it comes from its JavaScript roots] was correct.

'\/' === '/' in JavaScript, and JSON is valid JavaScript. However, why are the other ignored escapes (like \z) not allowed in JSON?

The key for this was reading http://www.cs.tut.fi/~jkorpela/www/revsol.html, followed by http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.2. The feature of the slash escape allows JSON to be embedded in HTML (as SGML) and XML.

Beginners needs practical examples. so try the following code.

public class Not_a_Number {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    String message = "0.0/0.0 is NaN.\nsimilarly Math.sqrt(-1) is NaN.";        
    String dottedLine = "------------------------------------------------";     

    Double numerator = -2.0;
    Double denominator = -2.0;      
    while (denominator <= 1) {
        Double x = numerator/denominator;           
        Double y = new Double (x);
        boolean z = y.isNaN();
        System.out.println("y =  " + y);
        System.out.println("z =  " + z);
        if (z == true){
            System.out.println(message);                
        }
        else {
            System.out.println("Hi, everyone"); 
        }
        numerator = numerator + 1;
        denominator = denominator +1;
        System.out.println(dottedLine);         
    } // end of while

} // end of main

} // end of class

The move_uploaded_file will return false if the file was not successfully moved you can put something into your code to alert you in a log if that happens, that should help you figure out why your having trouble renaming the file

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

Page should be refresh auto using meta tag

<meta http-equiv="Refresh" content="60"> 

content value in seconds.after one minute page should be refresh

Even though this solution is done with jQuery I though it may be useful for anyone doing columns to fit the screen size.

For columns starting at the top of the page, this solution is the simplest.

body,html{
  height:100%;
}

div#right{
  height:100%
}

For columns that are not starting at the top of the page (for example: if they are starting below the header).

<script>
     $(document).ready(function () {
        var column_height = $("body").height();
        column_height = column_height - 100; // 100 is the header height
        column_height = column_height + "px";
        $("#column").css("height",column_height);
    });
</script>

First method applies the body height to it and the columns as well, which means that is starting_pixels + height100%.

The second method gets the height of page shown to the user by getting the height of the body and then subtracts the header size to know how much height is left to display the column.

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

I made a really cool jQuery plugin for handling all varieties of ellipsis of text is one called ThreeDots @ http://tpgblog.com/threedots

It's much more flexible than the CSS approaches, and supports much more advanced, customizable behaviors and interactions.

Enjoy.

The answer given by @ray above works perfectly, but make sure you are using the right path to open up the file. If you right click on your icon and click properties, you should see where the actual path is, just copy past that and it should work.

you can do it so simple:

First: For Example in Models you have User.cs with this implementation

public class User
 {
   public string username { get; set; }
   public string age { get; set; }
 } 

We are passing the empty model to user – This model would be filled with user’s data when he submits the form like this

public ActionResult Add()
{
  var model = new User();
  return View(model);
}

When you return the View by empty User as model, it maps with the structure of the form that you implemented. We have this on HTML side:

@model MyApp.Models.Student
@using (Html.BeginForm()) 
 {
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Student</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.username, htmlAttributes: new { 
                           @class = "control-label col-md-2" })
            <div class="col-md-10">
                 @Html.EditorFor(model => model.username, new { 
                                 htmlAttributes = new { @class = "form-
                                 control" } })
                 @Html.ValidationMessageFor(model => model.userame, "", 
                                            new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.age, htmlAttributes: new { @class 
                           = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.age, new { htmlAttributes = 
                                new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.age, "", new { 
                                           @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" 
                 />
            </div>
        </div>
   </div>
}

So on button submit you will use it like this

[HttpPost]
public ActionResult Add(User user)
 {
   // now user.username has the value that user entered on form
 }

INSERT
INTO    Employee 
        (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT  '001', 'John Doe', '1 River Walk, Green Street', state_id, position_id, manager_id
FROM    dual
JOIN    state s
ON      s.state_name = 'New York'
JOIN    positions p
ON      p.position_name = 'Sales Executive'
JOIN    manager m
ON      m.manager_name = 'Barry Green'

Note that but a single spelling mistake (or an extra space) will result in a non-match and nothing will be inserted.

Since Android Studio uses the new Gradle-based build system, you should be putting assets/ inside of the source sets (e.g., src/main/assets/).

In a typical Android Studio project, you will have an app/ module, with a main/ sourceset (app/src/main/ off of the project root), and so your primary assets would go in app/src/main/assets/. However:

• If you need assets specific to a build type, such as debug versus release, you can create sourcesets for those roles (e.g,. app/src/release/assets/)

• Your product flavors can also have sourcesets with assets (e.g., app/src/googleplay/assets/)

• Your instrumentation tests can have an androidTest sourceset with custom assets (e.g., app/src/androidTest/assets/), though be sure to ask the InstrumentationRegistry for getContext(), not getTargetContext(), to access those assets

Also, a quick reminder: assets are read-only at runtime. Use internal storage, external storage, or the Storage Access Framework for read/write content.

import * as saveAsFunctions from 'file-saver';
..........
....... 
let saveAs;
            beforeEach(() => {
                saveAs = jasmine.createSpy('saveAs');
            })
            it('should generate the excel on sample request details page', () => {
                spyOn(saveAsFunctions, 'saveAs').and.callFake(saveAs);
                expect(saveAsFunctions.saveAs).toHaveBeenCalled();
            })

This worked for me.

Just ran into the same problem. Installing the .NET framework on the target machine solved the problem.

Better yet, make sure all required dependencies are present in the machine where the code will be running.

With Rails 6.0.0, create your "stylesheet.css" stylesheet at app/assets/stylesheets.

You can use jQuery

<html> 
  <head> 
    <script src="jquery.js"></script> 
    <script> 
    $(function(){
      $("#divId").load("b.html"); 
    });
    </script> 
  </head> 

  <body> 
     <div id="divId" style="display:none;"></div>
  </body> 
</html>

on click event you can make it display block .

    viewStyle : {
    backgroundColor: '#F8F8F8',
    justifyContent: 'center',
    alignItems: 'center',
    height: 60,
    paddingTop: 15,
    shadowColor: '#000',
    shadowOffset: { width: 0, height: 2 },
    shadowOpacity: 0.2,
    marginBottom: 10,
    elevation: 2,
    position: 'relative'
},

Use marginBottom: 10

Note: This answer was originally posted here

I am posting this answer because I would like to share additional details about the available options that I did not find in the other answers

To create a DataFrame from an RDD of Rows, there are two main options:

1) As already pointed out, you could use toDF() which can be imported by import sqlContext.implicits._. However, this approach only works for the following types of RDDs:

• RDD[Int]
• RDD[Long]
• RDD[String]
• RDD[T <: scala.Product]

(source: Scaladoc of the SQLContext.implicits object)

The last signature actually means that it can work for an RDD of tuples or an RDD of case classes (because tuples and case classes are subclasses of scala.Product).

So, to use this approach for an RDD[Row], you have to map it to an RDD[T <: scala.Product]. This can be done by mapping each row to a custom case class or to a tuple, as in the following code snippets:

val df = rdd.map({ 
  case Row(val1: String, ..., valN: Long) => (val1, ..., valN)
}).toDF("col1_name", ..., "colN_name")

or

case class MyClass(val1: String, ..., valN: Long = 0L)
val df = rdd.map({ 
  case Row(val1: String, ..., valN: Long) => MyClass(val1, ..., valN)
}).toDF("col1_name", ..., "colN_name")

The main drawback of this approach (in my opinion) is that you have to explicitly set the schema of the resulting DataFrame in the map function, column by column. Maybe this can be done programatically if you don't know the schema in advance, but things can get a little messy there. So, alternatively, there is another option:

2) You can use createDataFrame(rowRDD: RDD[Row], schema: StructType) as in the accepted answer, which is available in the SQLContext object. Example for converting an RDD of an old DataFrame:

val rdd = oldDF.rdd
val newDF = oldDF.sqlContext.createDataFrame(rdd, oldDF.schema)

Note that there is no need to explicitly set any schema column. We reuse the old DF's schema, which is of StructType class and can be easily extended. However, this approach sometimes is not possible, and in some cases can be less efficient than the first one.

In PHP use the function htmlspecialchars() to escape < and >.

htmlspecialchars('<strong>something</strong>')

want to convert the column name Amount as float number with 2 decimals

CASE WHEN EXISTS (SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost')
     THEN  CAST ((SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost') AS VARCHAR)
            ELSE '' END AS FCost,

Try this:

SELECT ProductName,NumberofProducts ,NumberofProductssold
   FROM table1 
     JOIN table2
     ON table1.ProductName = table2.ProductName

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

Merging using an extension method. It does not throw exception when there are duplicate keys, but replaces those keys with keys from the second dictionary.

internal static class DictionaryExtensions
{
    public static Dictionary<T1, T2> Merge<T1, T2>(this Dictionary<T1, T2> first, Dictionary<T1, T2> second)
    {
        if (first == null) throw new ArgumentNullException("first");
        if (second == null) throw new ArgumentNullException("second");

        var merged = new Dictionary<T1, T2>();
        first.ToList().ForEach(kv => merged[kv.Key] = kv.Value);
        second.ToList().ForEach(kv => merged[kv.Key] = kv.Value);

        return merged;
    }
}

Usage:

Dictionary<string, string> merged = first.Merge(second);

The get_ddl procedure for a PACKAGE will return both spec AND body, so it will be better to change the query on the all_objects so the package bodies are not returned on the select.

So far I changed the query to this:

SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type, ' ', '_'), object_name, owner)
FROM all_OBJECTS
WHERE (OWNER = 'OWNER1')
and object_type not like '%PARTITION'
and object_type not like '%BODY'
order by object_type, object_name;

Although other changes might be needed depending on the object types you are getting...

Use the hashchange event:

window.addEventListener("hashchange", function(e) {
  // ...
})

If you need to support older browsers, check out the hashChange Event section in Modernizr's HTML5 Cross Browser Polyfills wiki page.

Try using Web API HttpClient

    static async Task RunAsync()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://domain.com/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


            // HTTP POST
            var obj = new MyObject() { Str = "MyString"};
            response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
            if (response.IsSuccessStatusCode)
            {
                response.//.. Contains the returned content.
            }
        }
    }

With large arrays, print_r can show far more information than is useful. You can truncate it like this, showing the first 2000 characters or however many you need.

  echo "<pre>" . substr(print_r($dataset, 1), 0, 2000) . "</pre>";

By default compiler tries to call parameterless constructor of base class.

In case if the base class doesn't have a parameterless constructor, you have to explicitly call it yourself:

public child(int i) : base(i){
Console.WriteLine("child");}

Besides the Stanford lib that tylerl mentioned. I found jsrsasign very useful (Github repo here:https://github.com/kjur/jsrsasign). I don't know how exactly trustworthy it is, but i've used its API of SHA256, Base64, RSA, x509 etc. and it works pretty well. In fact, it includes the Stanford lib as well.

If all you want to do is SHA256, jsrsasign might be a overkill. But if you have other needs in the related area, I feel it's a good fit.

If you only want to fetch the Google user id, name and picture for a visitor of your web app - here is my pure PHP service side solution for the year 2020 with no external libraries used -

If you read the Using OAuth 2.0 for Web Server Applications guide by Google (and beware, Google likes to change links to its own documentation), then you have to perform only 2 steps:

1. Present the visitor a web page asking for the consent to share her name with your web app
2. Then take the "code" passed by the above web page to your web app and fetch a token (actually 2) from Google.

One of the returned tokens is called "id_token" and contains the user id, name and photo of the visitor.

Here is the PHP code of a web game by me. Initially I was using Javascript SDK, but then I have noticed that fake user data could be passed to my web game, when using client side SDK only (especially the user id, which is important for my game), so I have switched to using PHP on the server side:

<?php

const APP_ID       = '1234567890-abcdefghijklmnop.apps.googleusercontent.com';
const APP_SECRET   = 'abcdefghijklmnopq';

const REDIRECT_URI = 'https://the/url/of/this/PHP/script/';
const LOCATION     = 'Location: https://accounts.google.com/o/oauth2/v2/auth?';
const TOKEN_URL    = 'https://oauth2.googleapis.com/token';
const ERROR        = 'error';
const CODE         = 'code';
const STATE        = 'state';
const ID_TOKEN     = 'id_token';

# use a "random" string based on the current date as protection against CSRF
$CSRF_PROTECTION   = md5(date('m.d.y'));

if (isset($_REQUEST[ERROR]) && $_REQUEST[ERROR]) {
    exit($_REQUEST[ERROR]);
}

if (isset($_REQUEST[CODE]) && $_REQUEST[CODE] && $CSRF_PROTECTION == $_REQUEST[STATE]) {
    $tokenRequest = [
        'code'          => $_REQUEST[CODE],
        'client_id'     => APP_ID,
        'client_secret' => APP_SECRET,
        'redirect_uri'  => REDIRECT_URI,
        'grant_type'    => 'authorization_code',
    ];

    $postContext = stream_context_create([
        'http' => [
            'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
            'method'  => 'POST',
            'content' => http_build_query($tokenRequest)
        ]
    ]);

    # Step #2: send POST request to token URL and decode the returned JWT id_token
    $tokenResult = json_decode(file_get_contents(TOKEN_URL, false, $postContext), true);
    error_log(print_r($tokenResult, true));
    $id_token    = $tokenResult[ID_TOKEN];
    # Beware - the following code does not verify the JWT signature! 
    $userResult  = json_decode(base64_decode(str_replace('_', '/', str_replace('-', '+', explode('.', $id_token)[1]))), true);

    $user_id     = $userResult['sub'];
    $given_name  = $userResult['given_name'];
    $family_name = $userResult['family_name'];
    $photo       = $userResult['picture'];

    if ($user_id != NULL && $given_name != NULL) {
        # print your web app or game here, based on $user_id etc.
        exit();
    }
}

$userConsent = [
    'client_id'     => APP_ID,
    'redirect_uri'  => REDIRECT_URI,
    'response_type' => 'code',
    'scope'         => 'profile',
    'state'         => $CSRF_PROTECTION,
];

# Step #1: redirect user to a the Google page asking for user consent
header(LOCATION . http_build_query($userConsent));

?>

You could use a PHP library to add additional security by verifying the JWT signature. For my purposes it was unnecessary, because I trust that Google will not betray my little web game by sending fake visitor data.

Also, if you want to get more personal data of the visitor, then you need a third step:

const USER_INFO    = 'https://www.googleapis.com/oauth2/v3/userinfo?access_token=';
const ACCESS_TOKEN = 'access_token'; 

# Step #3: send GET request to user info URL
$access_token = $tokenResult[ACCESS_TOKEN];
$userResult = json_decode(file_get_contents(USER_INFO . $access_token), true);

Or you could get more permissions on behalf of the user - see the long list at the OAuth 2.0 Scopes for Google APIs doc.

Finally, the APP_ID and APP_SECRET constants used in my code - you get it from the Google API console:

The new tests you wrote (directly or indirectly) use classes that log using Log4j.

Log4J needs to be configured for this logging to work properly.

Put a log4j.properties (or log4j.xml) file in the root of your test classpath.

It should have some basic configuration such as

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# An alternative logging format:
# log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n

An appender outputs to the console by default, but you can also explicitly set the target like this:

log4j.appender.A1.Target=System.out

This will redirect all output in a nice format to the console. More info can be found here in the Log4J manual,

Log4J Logging will then be properly configured and this warning will disappear.

Your question seems to be asking about which of the three examples you have given is the preferred approach.

Example 1 using the Reflection TestUtils is not a good approach for Unit testing. You really don't want to be loading the spring context at all for a unit test. Just mock and inject what is required as shown by your other examples.

You do want to load the spring context if you want to do some Integration testing, however I would prefer using @RunWith(SpringJUnit4ClassRunner.class) to perform the loading of the context along with @Autowired if you need access to its' beans explicitly.

Example 2 is a valid approach and the use of @RunWith(MockitoJUnitRunner.class) will remove the need to specify a @Before method and an explicit call to MockitoAnnotations.initMocks(this);

Example 3 is another valid approach that doesn't use @RunWith(...). You haven't instantiated your class under test HelloFacadeImpl explicitly, but you could have done the same with Example 2.

My suggestion is to use Example 2 for your unit testing as it reduces the code clutter. You can fall back to the more verbose configuration if and when you're forced to do so.

I tried adding a block like so:

@section styles{
    <link rel="Stylesheet" href="@Href("~/Content/MyStyles.css")" />
}

And a corresponding block in the _Layout.cshtml file:

<head>
<title>@ViewBag.Title</title>
@RenderSection("styles", false);
</head>

Which works! But I can't help but think there's a better way. UPDATE: Added "false" in the @RenderSection statement so your view won't 'splode when you neglect to add a @section called head.

I use Portecle, and it works like a charm.

1. Create a guard as seen below. 2. Install ngx-cookie-service to get cookies returned by external SSO. 3. Create ssoPath in environment.ts (SSO Login redirection). 4. Get the state.url and use encodeURIComponent.

import { Injectable } from '@angular/core';
import { CanActivate, Router, ActivatedRouteSnapshot, RouterStateSnapshot } from 
  '@angular/router';
import { CookieService } from 'ngx-cookie-service';
import { environment } from '../../../environments/environment.prod';

@Injectable()
export class AuthGuardService implements CanActivate {
  private returnUrl: string;
  constructor(private _router: Router, private cookie: CookieService) {}

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    if (this.cookie.get('MasterSignOn')) {
      return true;
    } else {
      let uri = window.location.origin + '/#' + state.url;
      this.returnUrl = encodeURIComponent(uri);      
      window.location.href = environment.ssoPath +  this.returnUrl ;   
      return false;      
    }
  }
}

If the format is "fixed" meaning you don't have to use other format you can have pure JavaScript instead of using whole library to format the date:

//Pad given value to the left with "0"_x000D_
function AddZero(num) {_x000D_
    return (num >= 0 && num < 10) ? "0" + num : num + "";_x000D_
}_x000D_
_x000D_
window.onload = function() {_x000D_
    var now = new Date();_x000D_
    var strDateTime = [[AddZero(now.getDate()), _x000D_
        AddZero(now.getMonth() + 1), _x000D_
        now.getFullYear()].join("/"), _x000D_
        [AddZero(now.getHours()), _x000D_
        AddZero(now.getMinutes())].join(":"), _x000D_
        now.getHours() >= 12 ? "PM" : "AM"].join(" ");_x000D_
    document.getElementById("Console").innerHTML = "Now: " + strDateTime;_x000D_
};

<div id="Console"></div>

The variable strDateTime will hold the date/time in the format you desire and you should be able to tweak it pretty easily if you need.

I'm using join as good practice, nothing more, it's better than adding strings together.

i was also facing the same issue, The possible solution is to install the gulp-sass module, but if you will run the below command npm install -g gulp-sass or npm install --save gulp-sass, This is not going to be updated on node-sass project's end.

This version of node-sass is missing (returns a 404) and google web-starter-kit v0.6.5 has depended on it for a long time, since Dec 2016. So, it has been working for a long time and must have just disappeared.

Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node":

HTTP error 404 Not Found

The only workaround is to upgrade node-sass: npm i gulp-sass@latest --save-dev to fix the issue.

It's working fine for me by the following way -

public async Task<object> TestMethod(TestModel model)
    {
        try
        {
            var apicallObject = new
            {
                Id= model.Id,
                name= model.Name
            };

            if (apicallObject != null)
            {
                var bodyContent = JsonConvert.SerializeObject(apicallObject);
                using (HttpClient client = new HttpClient())
                {
                    var content = new StringContent(bodyContent.ToString(), Encoding.UTF8, "application/json");
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                    client.DefaultRequestHeaders.Add("access-token", _token); // _token = access token
                    var response = await client.PostAsync(_url, content); // _url =api endpoint url
                    if (response != null)
                    {
                        var jsonString = await response.Content.ReadAsStringAsync();

                        try
                        {
                            var result = JsonConvert.DeserializeObject<TestModel2>(jsonString); // TestModel2 = deserialize object
                        }
                        catch (Exception e){
                            //msg
                            throw e;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return null;
    }

We can create a new CSS class for div.

 .div {
      position: absolute;
      left: 150px;
      width: 200px;
      height: 120px;
    }

This worked for me best:

$('.alert').on('close.bs.alert', function (e) {
    e.preventDefault();
    $(this).hide();
});

this happened with me when I accidentaly deleted the class reference from the xaml definition:

I've replaced the

<Window x:Class="myapp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

first line with this:

<RibbonWindow 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

I know this isn't the answer to the original question (because thats project builds on another machine), but the error message was the same, so maybe I'll help someone with this situation.

You can upload artifacts via their native publishing capabilities (e.g. maven deploy, npm publish).

You can also upload artifacts to "raw" repositories via a simple curl request, e.g.

curl --fail -u admin:admin123 --upload-file foo.jar 'http://my-nexus-server.com:8081/repository/my-raw-repo/'

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

I was trying to upgrade my anaconda 2 with anaconda 3. I tried installing Anaconda3-2018.12-Windows-x86 and Anaconda3-2019.03-Windows-x86_64 on my Windows 10 machine and failed with this error. For me, using Anaconda3-4.4.0-Windows-x86_64 for anaconda 3 worked the trick after trying everything listed in answers here.

You can make use of java.net.URL and/or java.net.URLConnection.

URL url = new URL("https://stackoverflow.com");

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
    for (String line; (line = reader.readLine()) != null;) {
        System.out.println(line);
    }
}

Also see the Oracle's simple tutorial on the subject. It's however a bit verbose. To end up with less verbose code, you may want to consider Apache HttpClient instead.

By the way: if your next question is "How to process HTML result?", then the answer is "Use a HTML parser. No, don't use regex for this.".

try use keyup.enter or keydown.enter

  <button type="submit" (keyup.enter)="search(...)">Search</button>

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

What most of the answers above fail to show is that there is no "One Size Fits All" answer to the original question.

In today's environment we have a large conglomerate of different hardware and software -- some is 32 bit, some is 64 bit, some is cutting edge and some is tried and true - reliable and never changing. Added to that is a variety of older and newer hardware, older and newer OSes, different vendors (Windows, Unixes, Apple, etc.) and a myriad of utilities and servers that go along. As hardware has improved and software is converted to 64 bit compatibility, there has necessarily been considerable delay in getting all the pieces of this very large and complex world to play nicely with the rapid pace of changes.

IMHO there is no one way to fix a problem. The solution is to research the possibilities and then by trial and error find what works best for your particular needs. Each user must determine what works for their system rather than using a cookie cutter approach.

I for example have a media server with a few very large files. The result is only about 400 files filling a 3 TB drive. Only 1% of the inodes are used but 95% of the total space is used. Someone else, with a lot of smaller files may run out of inodes before they come near to filling the space. (On ext4 filesystems as a rule of thumb, 1 inode is used for each file/directory.) While theoretically the total number of files that may be contained within a directory is nearly infinite, practicality determines that the overall usage determine realistic units, not just filesystem capabilities.

I hope that all the different answers above have promoted thought and problem solving rather than presenting an insurmountable barrier to progress.

This is the setup I use:

Before running the tests, execute:

export DISPLAY=:99
/etc/init.d/xvfb start

And after the tests:

/etc/init.d/xvfb stop

The init.d file I use looks like this:

#!/bin/bash

XVFB=/usr/bin/Xvfb
XVFBARGS="$DISPLAY -ac -screen 0 1024x768x16"
PIDFILE=${HOME}/xvfb_${DISPLAY:1}.pid
case "$1" in
  start)
    echo -n "Starting virtual X frame buffer: Xvfb"
    /sbin/start-stop-daemon --start --quiet --pidfile $PIDFILE --make-pidfile --background --exec $XVFB -- $XVFBARGS
    echo "."
    ;;
  stop)
    echo -n "Stopping virtual X frame buffer: Xvfb"
    /sbin/start-stop-daemon --stop --quiet --pidfile $PIDFILE
    echo "."
    ;;
  restart)
    $0 stop
    $0 start
    ;;
  *)
  echo "Usage: /etc/init.d/xvfb {start|stop|restart}"
  exit 1
esac
exit 0

Reinstall numpy-1.11.0_XXX.whl (for your Python) from www.lfd.uci.edu/~gohlke/pythonlibs. This file has the same name and version if compare with the variant downloaded by me earlier 29.03.2016, but its size and content differ from old variant. After re-installation error disappeared.

Second option - return back to scipy 0.17.0 from 0.17.1

P.S. I use Windows 64-bit version of Python 3.5.1, so can't guarantee that numpy for Python 2.7 is already corrected.

I think you can use eval. Something like this

def toclass(strcls):
    return eval(strcls)()

it seems you can directly call:

g = sns.factorplot("class", "survived", "sex",
                data=titanic, kind="bar",
                size=6, palette="muted",
               legend_out=False)

g._legend.set_bbox_to_anchor((.7, 1.1))

It happens also if your code is expecting Java Mail 1.4 and your jars are Java Mail 1.3. Happened to me when upgraded Pentaho Kettle

Looks fine to me:

You're sure you didn't on the settings globally or something? This is a clean installation of the beta on Windows 7. The developer tools report that the page is defaulting to IE9 Standard Mode.

Try using rextract. It will let you extract text using a regular expression and reformat it.

Example:

$ echo "This is 02G05 a test string 20-Jul-2012" | ./rextract '([\d]+G[\d]+)' '${1}'

2G05

You were almost there : just add theme(legend.title=element_blank())

ggplot(df, aes(x, y, colour=g)) +
  geom_line(stat="identity") + 
  theme(legend.position="bottom") +
  theme(legend.title=element_blank())

This page on Cookbook for R gives plenty of details on how to customize legends.

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

Let me suggest an answer similar to Scott Gardner's answer but with more laconic syntax using reduce. This solution removes duplicates from an array of custom objects (keeping the initial order)

// Custom Struct. Can be also class. 
// Need to be `equitable` in order to use `contains` method below
struct CustomStruct : Equatable {
      let name: String
      let lastName : String
    }

// conform to Equatable protocol. feel free to change the logic of "equality"
func ==(lhs: CustomStruct, rhs: CustomStruct) -> Bool {
  return (lhs.name == rhs.name && lhs.lastName == rhs.lastName)
}

let categories = [CustomStruct(name: "name1", lastName: "lastName1"),
                  CustomStruct(name: "name2", lastName: "lastName1"),
                  CustomStruct(name: "name1", lastName: "lastName1")]
print(categories.count) // prints 3

// remove duplicates (and keep initial order of elements)
let uniq1 : [CustomStruct] = categories.reduce([]) { $0.contains($1) ? $0 : $0 + [$1] }
print(uniq1.count) // prints 2 - third element has removed

And just if you are wondering how this reduce magic works - here is exactly the same, but using more expanded reduce syntax

let uniq2 : [CustomStruct] = categories.reduce([]) { (result, category) in
  var newResult = result
  if (newResult.contains(category)) {}
  else {
    newResult.append(category)
  }
  return newResult
}
uniq2.count // prints 2 - third element has removed

You can simply copy-paste this code into a Swift Playground and play around.

In Swift you can use a functional approach like this:

view.subviews.forEach { $0.removeFromSuperview() }

As a comparison, the imperative approach would look like this:

for subview in view.subviews {
    subview.removeFromSuperview()
}

These code snippets only work in iOS / tvOS though, things are a little different on macOS.

When creating a new project - Maven - Java application in Netbeans the IDE is not recognizing the Main class on 1st class entry. (in Step 8 below we see no classes).

When first a generic class is created and then the Main class is created Netbeans is registering the Main class and the app could be run and debugged.

Steps that worked for me:

1. Create new project - Maven - Java application (project created: mytest; package created: com.me.test)
2. Right-click package: com.me.test
3. New > Java Class > Named it 'Whatever' you want
4. Right-click package: com.me.test
5. New > Java Main Class > named it: 'Main' (must be 'Main')
6. Right click on Project mytest
7. Click on Properties
8. Click on Run > next to 'Main Class' text box: > Browse
9. You should see: com.me.test.Main
10. Select it and click "Select Main Class"

Hope this works for others as well.

Just in case someone is using Bootstrap, I was able to add more than one class:

<a href="" class="baseclass" th:classappend="${isAdmin} ?: 'text-danger font-italic' "></a>

This is due to the interfering messages that come on to the page. There are multiple frames on the page which communicate with the page using window message event and object. few of them can be third party services like cookieq for managing cookies, or may be cartwire an e-com integration service.

You need to handle the onmessage event to check from where the messages are coming, and then parse the JSON accordingly.

I faced a similar problem, where one of the integration was passing a JSON object and other was passing a string starting with u

IMO, it's better to use the install command in such situations. I was trying to make systemd-journald persistent across reboots.

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.

Infix to PostFix using Stack:

     Example: Infix-->         P-Q*R^S/T+U *V
     Postfix -->      PQRS^*T/-UV

     Rules:
    Operand ---> Add it to postfix
    "(" ---> Push it on the stack
    ")" ---> Pop and add to postfix all operators till 1st left parenthesis
   Operator ---> Pop and add to postfix those operators that have preceded 
          greater than or equal to the precedence of scanned operator.
          Push the scanned symbol operator on the stack

overflow: auto; or overflow: hidden; should do it I think.

round(value,significantDigit) is the ordinary solution, however this does not operate as one would expect from a math perspective when round values ending in 5. If the 5 is in the digit just after the one you're rounded to, these values are only sometimes rounded up as expected (i.e. 8.005 rounding to two decimal digits gives 8.01). For certain values due to the quirks of floating point math, they are rounded down instead!

i.e.

>>> round(1.0005,3)
1.0
>>> round(2.0005,3)
2.001
>>> round(3.0005,3)
3.001
>>> round(4.0005,3)
4.0
>>> round(1.005,2)
1.0
>>> round(5.005,2)
5.0
>>> round(6.005,2)
6.0
>>> round(7.005,2)
7.0
>>> round(3.005,2)
3.0
>>> round(8.005,2)
8.01

Weird.

Assuming your intent is to do the traditional rounding for statistics in the sciences, this is a handy wrapper to get the round function working as expected needing to import extra stuff like Decimal.

>>> round(0.075,2)

0.07

>>> round(0.075+10**(-2*5),2)

0.08

Aha! So based on this we can make a function...

def roundTraditional(val,digits):
   return round(val+10**(-len(str(val))-1), digits)

Basically this adds a value guaranteed to be smaller than the least given digit of the string you're trying to use round on. By adding that small quantity it preserve's round's behavior in most cases, while now ensuring if the digit inferior to the one being rounded to is 5 it rounds up, and if it is 4 it rounds down.

The approach of using 10**(-len(val)-1) was deliberate, as it the largest small number you can add to force the shift, while also ensuring that the value you add never changes the rounding even if the decimal . is missing. I could use just 10**(-len(val)) with a condiditional if (val>1) to subtract 1 more... but it's simpler to just always subtract the 1 as that won't change much the applicable range of decimal numbers this workaround can properly handle. This approach will fail if your values reaches the limits of the type, this will fail, but for nearly the entire range of valid decimal values it should work.

You can also use the decimal library to accomplish this, but the wrapper I propose is simpler and may be preferred in some cases.

Edit: Thanks Blckknght for pointing out that the 5 fringe case occurs only for certain values. Also an earlier version of this answer wasn't explicit enough that the odd rounding behavior occurs only when the digit immediately inferior to the digit you're rounding to has a 5.

You could use array_map(), set the first parameter to 'strtolower' (including the quotes) and the second parameter to $lower_case_array.

The Simple way is, to convert it to JSON String as below example:

Gson gson = new Gson();
String json = gson.toJson(myObj);

Then store the string in the shared preferences. Once you need it just get string from shared preferences and convert back to JSONArray or JSONObject(as per your requirement.)

Array into table. Array into div. JSON into table. JSON into div.

All are nicely handle this class. Click here to get a class

How to use it?

Just get and object

$obj = new Arrayinto();

Create an array you want to convert

$obj->array_object = array("AAA" => "1111",
                  "BBB" => "2222",
                  "CCC" => array("CCC-1" => "123",
                                 "CCC-2" => array("CCC-2222-A" => "CA2",
                                                  "CCC-2222=B" => "CB2"
                                                 )
                                )

                 );

If you want to convert Array into table. Call this.

$result = $obj->process_table();

If you want to convert Array into div. Call this.

$result = $obj->process_div();

Let suppose if you have a JSON

$obj->json_string = '{
            "AAA":"11111",
            "BBB":"22222",
            "CCC":[
                    {
                        "CCC-1":"123"
                    },
                    {
                        "CCC-2":"456"
                    }
                  ] 
         }
        ';

You can convert into table/div like this

$result = $obj->process_json('div');

OR

$result = $obj->process_json('table');

Although there isn't a syntax, you can still get close by using the built-in block comment buttons:

If you're not viewing the Edit toolbar already, right-click on the toolbar and enable the Edit toolbar:

Then, select a block of code and hit the "Comment Block" button; or if it's already commented out, use the "Uncomment Block" button:

Fast and easy!

Statement s = cd.createStatement();
ResultSet r = s.executeQuery("SELECT COUNT(*) AS rowcount FROM FieldMaster");
r.next();
int count = r.getInt("rowcount");
r.close();
System.out.println("MyTable has " + count + " row(s).");

Sometimes JDBC does not support following method gives Error like `TYPE_FORWARD_ONLY' use this solution

Sqlite does not support in JDBC.

resultSet.last();
size = resultSet.getRow();
resultSet.beforeFirst();

So at that time use this solution.

Thanks..

After writing a single activity, there comes a need to transition to another activity to perform another task either with or without information from the first activity.

Android platform allows transition by means of Intent Interface.

Words are taken from here: Using Intent Demo and i suggest you to go through this example because they also have provided a code file as well. so you can use it and easily understand the same.

For the case

<element class="a">
  <element class="b c">
  </element>
</element>

You would need to put a space in between .a and .b.c

$('.a .b.c')

The reason is that when instantiating a class template, all its declarations (not the definitions) of its member functions are instantiated too. The class template is instantiated precisely when the full definition of a specialization is required. That is the case when it is used as a base class for example, as in your case.

So what happens is that A<B> is instantiated at

class B : public A<B>

at which point B is not a complete type yet (it is after the closing brace of the class definition). However, A<B>::action's declaration requires B to be complete, because it is crawling in the scope of it:

Subclass::mytype

What you need to do is delaying the instantiation to some point at which B is complete. One way of doing this is to modify the declaration of action to make it a member template.

template<typename T>
void action(T var) {
    (static_cast<Subclass*>(this))->do_action(var);
}

It is still type-safe because if var is not of the right type, passing var to do_action will fail.

You can do this using OPENROWSET as suggested in this answer. Reposting Slogmeister Extrarodinare answer:

Use T-SQL

INSERT INTO OPENROWSET ('Microsoft.ACE.OLEDB.12.0','Text;Database=D:\;HDR=YES;FMT=Delimited','SELECT * FROM [FileName.csv]')
SELECT Field1, Field2, Field3 FROM DatabaseName

But, there are couple of caveats:

1. You need to have the Microsoft.ACE.OLEDB.12.0 provider available. The Jet 4.0 provider will work, too, but it's ancient, so I used this one instead.

2. The .CSV file will have to exist already. If you're using headers (HDR=YES), make sure the first line of the .CSV file is a delimited list of all the fields.

Use the following command on your terminal (Ctrl + Alt + T):-

$ conda activate
$ anaconda-navigator

Adding a third option. The "shorthand" version of @AndrewD's second option.

1. SheetObject.ListObjects("TableName")
2. Application.Range("TableName").ListObject
3. [TableName].ListObject

^{Yes, there are no quotes in the bracket reference.}

Running:

npm install

from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).

You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.

To prevent this, just create a symlink to the relocated node_modules from your app dir:

ln -s ../node_modules node_modules

Whatsapp store all messages in an encrypted database (pyCrypt) which is very easy to decipher using Python.

Disclaimer: I researched and wrote this extensive guide.

And if you want to run a second function after the first one finishes, see this stackoverflow answer.

Note that in .NET 4.0 there are (supposedly) iterator-based (rather than array-based) file functions built in:

foreach (string file in Directory.EnumerateFiles(path, "*.*", SearchOption.AllDirectories))
{
    Console.WriteLine(file);
}

At the moment I'd use something like below; the inbuilt recursive method breaks too easily if you don't have access to a single sub-dir...; the Queue<string> usage avoids too much call-stack recursion, and the iterator block avoids us having a huge array.

static void Main() {
    foreach (string file in GetFiles(SOME_PATH)) {
        Console.WriteLine(file);
    }
}

static IEnumerable<string> GetFiles(string path) {
    Queue<string> queue = new Queue<string>();
    queue.Enqueue(path);
    while (queue.Count > 0) {
        path = queue.Dequeue();
        try {
            foreach (string subDir in Directory.GetDirectories(path)) {
                queue.Enqueue(subDir);
            }
        }
        catch(Exception ex) {
            Console.Error.WriteLine(ex);
        }
        string[] files = null;
        try {
            files = Directory.GetFiles(path);

        if (files != null) {
            for(int i = 0 ; i < files.Length ; i++) {
                yield return files[i];
            }

That query is failing and returning false.

Put this after mysqli_query() to see what's going on.

if (!$check1_res) {
    printf("Error: %s\n", mysqli_error($con));
    exit();

As short as @jumbo's answer is :-) you can do it even more tersely. This just returns the Count property of the array returned by the antecedent sub-expression:

@(Get-Alias).Count

A couple points to note:

1. You can put an arbitrarily complex expression in place of Get-Alias, for example:

   @(Get-Process | ? { $_.ProcessName -eq "svchost" }).Count
   

2. The initial at-sign (@) is necessary for a robust solution. As long as the answer is two or greater you will get an equivalent answer with or without the @, but when the answer is zero or one you will get no output unless you have the @ sign! (It forces the Count property to exist by forcing the output to be an array.)

2012.01.30 Update

The above is true for PowerShell V2. One of the new features of PowerShell V3 is that you do have a Count property even for singletons, so the at-sign becomes unimportant for this scenario.

This happens because document.write would overwrite your existing code therefore place your div before your javascript code. e.g.:

CSS:

#mydiv { 
  visibility:hidden;
 }

Inside your html file

<div id="mydiv">
   <p>Hello world</p>
</div>
<script type="text/javascript">
   document.getElementById('mydiv').style.visibility='visible';
</script>

Use USE. This will enable you to select the database.

USE photogallery;

12.8.4: USE Syntax

You can also specify the database you want when connecting:

$ mysql -u user -p photogallery

On openSUSE you need to install the packages openldap2-devel, cyrus-sasl-devel, python-devel and libopenssl-devel.

zypper install openldap2-devel cyrus-sasl-devel python-devel libopenssl-devel

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>3.0.0.RELEASE</version>
</dependency>

This will do:

db.getCollectionNames().forEach(c => {
    db[c].find().forEach(d => {
        print(c); 
        printjson(d)
    })
})

Agree with 2nd most vote answer that it will make big difference when using LEFT JOIN or RIGHT JOIN. Actually, the two statements below are equivalent. So you can see that AND clause is doing a filter before JOIN while the WHERE clause is doing a filter after JOIN.

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN dbo.Orders AS ORD 
ON CUS.CustomerID = ORD.CustomerID
AND ORD.OrderDate >'20090515'

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN (SELECT * FROM dbo.Orders WHERE OrderDate >'20090515') AS ORD 
ON CUS.CustomerID = ORD.CustomerID

1. Download the plugin.
2. Inside Jenkins: Manage Jenkins ? Manage Plugins ? There is a tab called Advanced and on that page there is an option to upload a plugin (the extension of the file must be hpi).

Sometimes, when you download plugins you may get (.zip) files then just rename with (.hpi) and use the UI to install the plugin.

The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:

...
$('#mySelector')
  .on('show.bs.modal', function(e) {
  var mid;


  if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) 
    mid = $(e.relatedTarget).data('id');
  else
    mid = $(event.target).closest('tr').data('id');

...

if you want to get text of a selected option (chosen get display selected value)

 $("#select-id").chosen().find("option:selected" ).text();

What you are looking for is called a Kalman Filter. It's frequently used to smooth navigational data. It is not necessarily trivial, and there is a lot of tuning you can do, but it is a very standard approach and works well. There is a KFilter library available which is a C++ implementation.

My next fallback would be least squares fit. A Kalman filter will smooth the data taking velocities into account, whereas a least squares fit approach will just use positional information. Still, it is definitely simpler to implement and understand. It looks like the GNU Scientific Library may have an implementation of this.

Here is a ready to run source code for random number generator using c taken from this site: http://www.random-number.com/random-number-c/ . The implementation here is more general (a function that gets 3 parameters: min,max and number of random numbers to generate)

#include <time.h>
#include <stdlib.h>
#include <stdio.h>

// the random function
void RandomNumberGenerator(const int nMin, const int nMax, const int  nNumOfNumsToGenerate)
{
  int nRandonNumber = 0;
  for (int i = 0; i < nNumOfNumsToGenerate; i++)
  {
    nRandonNumber = rand()%(nMax-nMin) + nMin;
    printf("%d ", nRandonNumber);
  }
  printf("\n");
}

void main()
{
  srand(time(NULL));
  RandomNumberGenerator(1,70,5);
}

It would be something like this

function CustomInputBox([string] $title, [string] $message, [string] $defaultText) 
{
$inputObject = new-object -comobject MSScriptControl.ScriptControl
$inputObject.language = "vbscript" 
$inputObject.addcode("function getInput() getInput = inputbox(`"$message`",`"$title`" , `"$defaultText`") end function" ) 
$_userInput = $inputObject.eval("getInput") 

return $_userInput
}

Then you can call the function similar to this.

$userInput = CustomInputBox "User Name" "Please enter your name." ""
if ( $userInput -ne $null ) 
{
 echo "Input was [$userInput]"
}
else
{
 echo "User cancelled the form!"
}

This is the most simple way to do this that I can think of.

This Python script has GUI to select with explorer a Ipython Notebook you want to convert to pdf. The approach with wkhtmltopdf is the only approach I found works well and provides high quality pdfs. Other approaches described here are problematic, syntax highlighting does not work or graphs are messed up.

You'll need to install wkhtmltopdf: http://wkhtmltopdf.org/downloads.html

and Nbconvert

pip install nbconvert
# OR
conda install nbconvert

Python script

# Script adapted from CloudCray
# Original Source: https://gist.github.com/CloudCray/994dd361dece0463f64a
# 2016--06-29
# This will create both an HTML and a PDF file

import subprocess
import os
from Tkinter import Tk
from tkFileDialog import askopenfilename

WKHTMLTOPDF_PATH = "C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf"  # or wherever you keep it

def export_to_html(filename):
    cmd = 'ipython nbconvert --to html "{0}"'
    subprocess.call(cmd.format(filename), shell=True)
    return filename.replace(".ipynb", ".html")


def convert_to_pdf(filename):
    cmd = '"{0}" "{1}" "{2}"'.format(WKHTMLTOPDF_PATH, filename, filename.replace(".html", ".pdf"))
    subprocess.call(cmd, shell=True)
    return filename.replace(".html", ".pdf")


def export_to_pdf(filename):
    fn = export_to_html(filename)
    return convert_to_pdf(fn)

def main():
    print("Export IPython notebook to PDF")
    print("    Please select a notebook:")

    Tk().withdraw() # Starts in folder from which it is started, keep the root window from appearing 
    x = askopenfilename() # show an "Open" dialog box and return the path to the selected file
    x = str(x.split("/")[-1])

    print(x)

    if not x:
        print("No notebook selected.")
        return 0
    else:
        fn = export_to_pdf(x)
        print("File exported as:\n\t{0}".format(fn))
        return 1

main()

Another approach to solve this is to use the following module.

node_extra_ca_certs_mozilla_bundle

This module can work without any code modification by generating a PEM file that includes all root and intermediate certificates trusted by Mozilla. You can use the following environment variable (Works with Nodejs v7.3+),

NODE_EXTRA_CA_CERTS

To generate the PEM file to use with the above environment variable. You can install the module using:

npm install --save node_extra_ca_certs_mozilla_bundle

and then launch your node script with an environment variable.

NODE_EXTRA_CA_CERTS=node_modules/node_extra_ca_certs_mozilla_bundle/ca_bundle/ca_intermediate_root_bundle.pem node your_script.js

Other ways to use the generated PEM file are available at:

https://github.com/arvind-agarwal/node_extra_ca_certs_mozilla_bundle

NOTE: I am the author of the above module.

With this command you will see all changes in the repository path/to/repo that were committed in revision <revision>:

svn diff -c <revision> path/to/repo

The -c indicates that you would like to look at a changeset, but there are many other ways you can look at diffs and changesets. For example, if you would like to know which files were changed (but not how), you can issue

svn log -v -r <revision>

Or, if you would like to show at the changes between two revisions (and not just for one commit):

svn diff -r <revA>:<revB> path/to/repo

I usually do it this way when it's a quite a few rows:

1. Select all sproc parameters in a dataset with SQL Management Studio
2. Right-click -> Copy
3. Paste in to excel
4. Create single-row sql statements with a formula like '="EXEC schema.mysproc @param=" & A2' in a new excel column. (Where A2 is your excel column containing the parameter)
5. Copy the list of excel statements into a new query in SQL Management Studio and execute.
6. Done.

(On larger datasets i'd use one of the solutions mentioned above though).

my solution

$(window).scroll(function(){
        if($(this).scrollTop()>425) {
            $("#theRelative").css("margin-top",$(this).scrollTop()-425);
            }   else {
                $("#theRelative").css("margin-top",$(this).scrollTop()-0);
                }
            });
            });

I have never seen it done that way in JavaScript. If you want a function with optional parameters that get assigned default values if the parameters are omitted, here's a way to do it:

 function(a, b) {
      if (typeof a == "undefined") {
        a = 10;
      }

      if (typeof b == "undefined") {
        a = 20;
      }

      alert("a: " + a + " b: " + b);
    }

You have to mark the single letter as optional too:

([A-Z]{1})? +.*? +

or make the whole part optional

(([A-Z]{1}) +.*? +)?

Request Dispatcher is an Interface which is used to dispatch the request or response from web resource to the another web resource. It contains mainly two methods.

1. request.forward(req,res): This method is used forward the request from one web resource to another resource. i.e from one servlet to another servlet or from one web application to another web appliacation.

2. response.include(req,res): This method is used include the response of one servlet to another servlet

NOTE: BY using Request Dispatcher we can forward or include the request or responses with in the same server.

request.sendRedirect(): BY using this we can forward or include the request or responses across the different servers. In this the client gets a intimation while redirecting the page but in the above process the client will not get intimation

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:

Example:

// Non-consecutive 3number keys are OK for PHP
// but not for a JavaScript array
$array = array(
  2 => array("Afghanistan", 32, 13),
  4 => array("Albania", 32, 12)
);

// array_values() removes the original keys and replaces
// with plain consecutive numbers
$out = array_values($array);
json_encode($out);
// [["Afghanistan", 32, 13], ["Albania", 32, 12]]

Android comes with a built-in YesNoPreference class that does exactly what you want (a confirm dialog with yes and no options). See the official source code here.

Unfortunately, it is in the com.android.internal.preference package, which means it is a part of Android's private APIs and you cannot access it from your application (private API classes are subject to change without notice, hence the reason why Google does not let you access them).

Solution: just re-create the class in your application's package by copy/pasting the official source code from the link I provided. I've tried this, and it works fine (there's no reason why it shouldn't).

You can then add it to your preferences.xml like any other Preference. Example:

<com.example.myapp.YesNoPreference
    android:dialogMessage="Are you sure you want to revert all settings to their default values?"
    android:key="com.example.myapp.pref_reset_settings_key"
    android:summary="Revert all settings to their default values."
    android:title="Reset Settings" />

Which looks like this:

Check if that file is included in Build Phases -> Compiled Sources

I had precisely this problem, but I needed sequential plots to have highly contrasting color. I was also doing plots with a common sub-plot containing reference data, so I wanted the color sequence to be consistently repeatable.

I initially tried simply generating colors randomly, reseeding the RNG before each plot. This worked OK (commented-out in code below), but could generate nearly indistinguishable colors. I wanted highly contrasting colors, ideally sampled from a colormap containing all colors.

I could have as many as 31 data series in a single plot, so I chopped the colormap into that many steps. Then I walked the steps in an order that ensured I wouldn't return to the neighborhood of a given color very soon.

My data is in a highly irregular time series, so I wanted to see the points and the lines, with the point having the 'opposite' color of the line.

Given all the above, it was easiest to generate a dictionary with the relevant parameters for plotting the individual series, then expand it as part of the call.

Here's my code. Perhaps not pretty, but functional.

from matplotlib import cm
cmap = cm.get_cmap('gist_rainbow')  #('hsv') #('nipy_spectral')

max_colors = 31   # Constant, max mumber of series in any plot.  Ideally prime.
color_number = 0  # Variable, incremented for each series.

def restart_colors():
    global color_number
    color_number = 0
    #np.random.seed(1)

def next_color():
    global color_number
    color_number += 1
    #color = tuple(np.random.uniform(0.0, 0.5, 3))
    color = cmap( ((5 * color_number) % max_colors) / max_colors )
    return color

def plot_args():  # Invoked for each plot in a series as: '**(plot_args())'
    mkr = next_color()
    clr = (1 - mkr[0], 1 - mkr[1], 1 - mkr[2], mkr[3])  # Give line inverse of marker color
    return {
        "marker": "o",
        "color": clr,
        "mfc": mkr,
        "mec": mkr,
        "markersize": 0.5,
        "linewidth": 1,
    }

My context is JupyterLab and Pandas, so here's sample plot code:

restart_colors()  # Repeatable color sequence for every plot

fig, axs = plt.subplots(figsize=(15, 8))
plt.title("%s + T-meter"%name)

# Plot reference temperatures:
axs.set_ylabel("°C", rotation=0)
for s in ["T1", "T2", "T3", "T4"]:
    df_tmeter.plot(ax=axs, x="Timestamp", y=s, label="T-meter:%s" % s, **(plot_args()))

# Other series gets their own axis labels
ax2 = axs.twinx()
ax2.set_ylabel(units)

for c in df_uptime_sensors:
    df_uptime[df_uptime["UUID"] == c].plot(
        ax=ax2, x="Timestamp", y=units, label="%s - %s" % (units, c), **(plot_args())
    )

fig.tight_layout()
plt.show()

The resulting plot may not be the best example, but it becomes more relevant when interactively zoomed in.

I added a ticket to add an option of some sort here:

https://github.com/pydata/pandas/issues/1450

In the meantime, result.fillna('') should do what you want

EDIT: in the development version (to be 0.8.0 final) if you specify an empty list of na_values, empty strings will stay empty strings in the result

Nowadays you can also use lazy_eval function from lazyeval package.

> lazyeval::lazy_eval("5+5")
[1] 10

Maybe

SELECT count(*) FROM (
    SELECT COUNT(*) FROM Movies GROUP BY ID HAVING count(Genre) = 4
) AS the_count_total

although that would not be the sum of all the movies, just how many have 4 genre's.

So maybe you want

SELECT sum(
    SELECT COUNT(*) FROM Movies GROUP BY ID having Count(Genre) = 4
) as the_sum_total

git pull is nothing but git fetch followed by git merge. So what you can do is

git fetch remote example_branch

git merge <commit_hash>

If you are using iTerm this command will open a new tab:

osascript -e 'tell application "iTerm" to activate' -e 'tell application "System Events" to tell process "iTerm" to keystroke "t" using command down'

In case you want the left and right elements to wrap content but have the middle space

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>
    <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
</LinearLayout>

There's a very nice package called nb_dev which is designed for authoring Python packages in Jupyter Notebooks. Like nbconvert, it can turn a notebook into a .py file, but it is more flexible and powerful because it has a lot of nice additional authoring features to help you develop tests, documentation, and register packages on PyPI. It was developed by the fast.ai folks.

It has a bit of a learning curve, but the documentation is good and it is not difficult overall.

As other users have pointed out, we use expression(). I'd like to answer the original question which involves a comma in the subscript:

How can I write v 1,2 with 1,2 as subscripts?

plot(1:10, 11:20 , main=expression(v["1,2"]))

Also, I'd like to add the reference for those looking to find the full expression syntax in R plotting: For more information see the ?plotmath help page. Running demo(plotmath) will showcase many expressions and relevant syntax.

Remember to use * to join different types of text within an expression.

Here is some of the sample output from demo(plotmath):

if you want to solve this problem without migrating to AndroidX (I don't recommend it)

this manifest merger issue is related to one of your dependency using androidX.

you need to decrease this dependency's release version. for my case :

I was using google or firebase

api 'com.google.android.gms:play-services-base:17.1.0'

I have to decrease it 15.0.1 to use in support library.

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

Here is a solution that only scrolls to top of Component if first time visiting for EACH component (in case you need to do something different per component):

In each Component:

export class MyComponent implements OnInit {

firstLoad: boolean = true;

...

ngOnInit() {

  if(this.firstLoad) {
    window.scroll(0,0);
    this.firstLoad = false;
  }
  ...
}

This line right here:

export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native:$JAVA_LIBRARY_PATH

From KunBetter's answer, worked for me. Just append it to .bashrc file and reload .bashrc contents

$ source ~/.bashrc

I converted the 'fast quick sort' algorithm to VBA, if anyone else wants it.

I have it optimized to run on an array of Int/Longs but it should be simple to convert it to one that works on arbitrary comparable elements.

Private Sub QuickSort(ByRef a() As Long, ByVal l As Long, ByVal r As Long)
    Dim M As Long, i As Long, j As Long, v As Long
    M = 4

    If ((r - l) > M) Then
        i = (r + l) / 2
        If (a(l) > a(i)) Then swap a, l, i '// Tri-Median Methode!'
        If (a(l) > a(r)) Then swap a, l, r
        If (a(i) > a(r)) Then swap a, i, r

        j = r - 1
        swap a, i, j
        i = l
        v = a(j)
        Do
            Do: i = i + 1: Loop While (a(i) < v)
            Do: j = j - 1: Loop While (a(j) > v)
            If (j < i) Then Exit Do
            swap a, i, j
        Loop
        swap a, i, r - 1
        QuickSort a, l, j
        QuickSort a, i + 1, r
    End If
End Sub

Private Sub swap(ByRef a() As Long, ByVal i As Long, ByVal j As Long)
    Dim T As Long
    T = a(i)
    a(i) = a(j)
    a(j) = T
End Sub

Private Sub InsertionSort(ByRef a(), ByVal lo0 As Long, ByVal hi0 As Long)
    Dim i As Long, j As Long, v As Long

    For i = lo0 + 1 To hi0
        v = a(i)
        j = i
        Do While j > lo0
            If Not a(j - 1) > v Then Exit Do
            a(j) = a(j - 1)
            j = j - 1
        Loop
        a(j) = v
    Next i
End Sub

Public Sub sort(ByRef a() As Long)
    QuickSort a, LBound(a), UBound(a)
    InsertionSort a, LBound(a), UBound(a)
End Sub

I tried the above answer - using page.html#ID_name it gave me a 404 page doesn't exist error.

Then instead of using .html, I simply put a slash / before the # and that worked fine. So my example on the sending page between the link tags looks like:

<a href= "http://my website.com/target-page/#El_Chorro">El Chorro</a>

Just use / instead of .html.

You are defining your array as xlValidateList(), so when you try to assign the type, it gets confused as to what you are trying to assign to the type.

Instead, try this:

Dim MyList(5) As String
MyList(0) = 1
MyList(1) = 2
MyList(2) = 3
MyList(3) = 4
MyList(4) = 5
MyList(5) = 6

With Range("A1").Validation
    .Delete
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
         Operator:=xlBetween, Formula1:=Join(MyList, ",")
End With

Both John Conde's and ryeballar's answers are correct and will work.

If you want to get too geeky:

• John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center and it has to decide whether to add/remove left), when clearly only one is needed.

• Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)

So, you can do the following as an alternative:

ng-class="{true:'center',false:'left'}[page.isSelected(1)]"

the easiest way to do this is to wrap your sockets in ObjectInput/OutputStreams and send serialized java objects. you can create classes which contain the relevant data, and then you don't need to worry about the nitty gritty details of handling binary protocols. just make sure that you flush your object streams after you write each object "message".

Technically the answer of zlovelady is preferable, but as I had only to remove items from the navigation, the approach of unsetting the not-needed navigation items in the template was the fastest/easiest way for me:

Just duplicate

app/design/frontend/base/default/template/customer/account/navigation

to

app/design/frontend/YOUR_THEME/default/template/customer/account/navigation

and unset the unneeded navigation items before the get rendered, e.g.:

<?php $_links = $this->getLinks(); ?>    
<?php 
    unset($_links['recurring_profiles']);
?>

I am not sure about Python but most languages have push/append function for arrays.

I've found it helpful to go into my "tmp" folder and delete all hanging rsession files. This usually frees any memory that seems to be "stuck".

Year 2020, Installing Cocoapods v1.9.1 in Mac OS Catalina

.then returns a promise in async function.

Good Example would be:

var doSome = new Promise(function(resolve, reject){
    resolve('I am doing something');
});

doSome.then(function(value){
    console.log(value);
});

To add another logic to it, you can also add the reject('I am the rejected param') call the function and console.log it.

You can use the Assembly.GetManifestResourceStream Method:

1. Add the following usings

   using System.IO;
   using System.Reflection;
   

2. Set property of relevant file:
   Parameter Build Action with value Embedded Resource

3. Use the following code

   var assembly = Assembly.GetExecutingAssembly();
   var resourceName = "MyCompany.MyProduct.MyFile.txt";
   
   using (Stream stream = assembly.GetManifestResourceStream(resourceName))
   using (StreamReader reader = new StreamReader(stream))
   {
       string result = reader.ReadToEnd();
   }
   

   resourceName is the name of one of the resources embedded in assembly. For example, if you embed a text file named "MyFile.txt" that is placed in the root of a project with default namespace "MyCompany.MyProduct", then resourceName is "MyCompany.MyProduct.MyFile.txt". You can get a list of all resources in an assembly using the Assembly.GetManifestResourceNames Method.

A no brainer astute to get the resourceName from the file name only (by pass the namespace stuff):

string resourceName = assembly.GetManifestResourceNames()
  .Single(str => str.EndsWith("YourFileName.txt"));

A complete example:

public string ReadResource(string name)
{
    // Determine path
    var assembly = Assembly.GetExecutingAssembly();
    string resourcePath = name;
    // Format: "{Namespace}.{Folder}.{filename}.{Extension}"
    if (!name.StartsWith(nameof(SignificantDrawerCompiler)))
    {
        resourcePath = assembly.GetManifestResourceNames()
            .Single(str => str.EndsWith(name));
    }

    using (Stream stream = assembly.GetManifestResourceStream(resourcePath))
    using (StreamReader reader = new StreamReader(stream))
    {
        return reader.ReadToEnd();
    }
}

CaseInsensitiveString and String are different objects. You can't do:

CaseInsensitiveString cis = "Polish";

because "Polish" is a String, not a CaseInsensitiveString. If String extended CaseInsensitiveString String then you'd be OK, but obviously it doesn't.

And don't worry about the construction here, you won't be making unecessary objects. If you look at the code of the constructor, all it's doing is storing a reference to the string you passed in. Nothing extra is being created.

In the String s = new String("foobar") case it's doing something different. You are first creating the literal string "foobar", then creating a copy of it by constructing a new string out of it. There's no need to create that copy.

If you keep grabbing bits from your data, you might want to use a bitfield. You'll just have to set up a struct and load it with only ones and zeroes:

struct bitfield{
    unsigned int bit : 1
}
struct bitfield *bitstream;

then later on load it like this (replacing char with int or whatever data you are loading):

long int i;
int j, k;
unsigned char c, d;

bitstream=malloc(sizeof(struct bitfield)*charstreamlength*sizeof(char));
for (i=0; i<charstreamlength; i++){
    c=charstream[i];
    for(j=0; j < sizeof(char)*8; j++){
        d=c;
        d=d>>(sizeof(char)*8-j-1);
        d=d<<(sizeof(char)*8-1);
        k=d;
        if(k==0){
            bitstream[sizeof(char)*8*i + j].bit=0;
        }else{
            bitstream[sizeof(char)*8*i + j].bit=1;
        }
    }
}

Then access elements:

bitstream[bitpointer].bit=...

or

...=bitstream[bitpointer].bit

All of this is assuming are working on i86/64, not arm, since arm can be big or little endian.

A Textblock itself can't do vertical alignment

The best way to do this that I've found is to put the textblock inside a border, so the border does the alignment for you.

<Border BorderBrush="{x:Null}" Height="50">
    <TextBlock TextWrapping="Wrap" Text="Some Text" VerticalAlignment="Center"/>
</Border>

Note: This is functionally equivalent to using a grid, it just depends how you want the controls to fit in with the rest of your layout as to which one is more suitable

You are using jQuery(document).ready(function($) {} means here you are using jQuery instead of $. So to resolve your issue use following code.

jQuery("#submittername").text(submitter_name);

This will resolve your problem.

It seems impossible to prevent spinners from appearing in Opera. As a temporary workaround, you can make room for the spinners. As far as I can tell, the following CSS adds just enough padding, only in Opera:

noindex:-o-prefocus,
input[type=number] {
    padding-right: 1.2em;
}

In that case you don't want to insert size and color inside an array, but into an object

var options = { 
    'size': size,
    'color': color
  };

Afterwards you can access the sets of keys by

var keys = Object.keys( options );

You can simply write

new ArrayList<MyEnum>(Arrays.asList(MyEnum.values()));

There is a buffer limit of something like 1024. The read will simply hang mid paste or input. To solve this use the -e option.

http://linuxcommand.org/lc3_man_pages/readh.html

-e use Readline to obtain the line in an interactive shell

Change your read to read -e and annoying line input hang goes away.

You can use the in operator:

if "blah" not in somestring: 
    continue

In Swift-3 :

self.tableView.setContentOffset(CGPoint.zero, animated: true)

If the question isn't just "how to access an integer form of the timedelta?" but "how to convert the timedelta column in the dataframe to an int?" the answer might be a little different. In addition to the .dt.days accessor you need either df.astype or pd.to_numeric

Either of these options should help:

df['tdColumn'] = pd.to_numeric(df['tdColumn'].dt.days, downcast='integer')

or

df['tdColumn'] = df['tdColumn'].dt.days.astype('int16')

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

For AF_UNIX you can use call unlink (path); after close() socket in "server" app

1. Open phpMyAdmin in a browser and log in as root.
2. Create a database called phpmyadmin
3. Create a user called pma and set the "host" to the hostname or IP address of your web server (if the web server and MySQL are on the same box use localhost), make a note of the password, and grant the new user full control over the phpmyadmin database. It is recommended that this user does not have access to anything other than this database.
4. Go to the phpMyAdmin installation directory, where you should find a sub-directory called sql.
5. In sql you will find a file called create_tables.sql. Open it in a text editor.
6. In phpMyAdmin, select the phpmyadmin database and click on the "SQL" tab.
7. Copy/paste the entire text from create_tables.sql into the text box, and run the query.

8. Open the config.inc.php file in the phpMyAdmin install directory, and add the following lines (or change the existing settings if they are already there):

   $cfg['Servers'][1]['pmadb'] = 'phpmyadmin';
   $cfg['Servers'][1]['controluser'] = 'pma';
   $cfg['Servers'][1]['controlpass'] = '<your password>';
   
   // Note: The list below may grow as PMA evolves and more control tables are added
   // Use your common sense! Don't just blindly copypasta, look at what it means!
   $cfg['Servers'][1]['bookmarktable'] = 'pma_bookmark';
   $cfg['Servers'][1]['relation'] = 'pma_relation';
   $cfg['Servers'][1]['userconfig'] = 'pma_userconfig';
   $cfg['Servers'][1]['table_info'] = 'pma_table_info';
   $cfg['Servers'][1]['column_info'] = 'pma_column_info';
   $cfg['Servers'][1]['history'] = 'pma_history';
   $cfg['Servers'][1]['recent'] = 'pma_recent';
   $cfg['Servers'][1]['table_uiprefs'] = 'pma_table_uiprefs';
   $cfg['Servers'][1]['tracking'] = 'pma_tracking';
   $cfg['Servers'][1]['table_coords'] = 'pma_table_coords';
   $cfg['Servers'][1]['pdf_pages'] = 'pma_pdf_pages';
   $cfg['Servers'][1]['designer_coords'] = 'pma_designer_coords';
   

9. Save and close the file.

IMPORTANT - PMA loads the config on login, evaluates it and stores it into the session data so the message will not disappear until you do this:

10. Log out of phpMyAdmin and log in again

Problem solved.

C99 does, if you have

#include <stdbool.h> 

If the compiler does not support C99, you can define it yourself:

// file : myboolean.h
#ifndef MYBOOLEAN_H
#define MYBOOLEAN_H

#define false 0
#define true 1
typedef int bool; // or #define bool int

#endif

(but note that this definition changes ABI for bool type so linking against external libraries which were compiled with properly defined bool may cause hard-to-diagnose runtime errors).

DisplayMetrics dimension = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dimension);
int w = dimension.widthPixels;
int h = dimension.heightPixels;

In Python, "privacy" depends on "consenting adults'" levels of agreement - you can't force it (any more than you can in real life;-). A single leading underscore means you're not supposed to access it "from the outside" -- two leading underscores (w/o trailing underscores) carry the message even more forcefully... but, in the end, it still depends on social convention and consensus: Python's introspection is forceful enough that you can't handcuff every other programmer in the world to respect your wishes.

((Btw, though it's a closely held secret, much the same holds for C++: with most compilers, a simple #define private public line before #includeing your .h file is all it takes for wily coders to make hash of your "privacy"...!-))

You are not using the "null" and therefore you don't get the exception. If you want the NullPointer, just do

String s = null;
s = s.toString() + "hello";

And I think what you want to do is:

String s = "";
s = s + "hello";

Numbers have higher precedence than strings so of course the + operators want to convert your strings into numbers before adding.

You could do:

print 'There are ' + CONVERT(varchar(10),@Number) +
      ' alias combinations did not match a record'

or use the (rather limited) formatting facilities of RAISERROR:

RAISERROR('There are %i alias combinations did not match a record',10,1,@Number)

I found netlimiter4 to be the best solution for throttling data to emulators. It provides for granular control through a decent gui and gives you graphical feedback on the data throughput to each process. Currently in a free beta. screenshot

There are apps available on the play store to throttle to actual devices but they require root(I cant provide any advice as to how well they work, if at at all - YMMV.)

search for bradybound on the play store, I can't post more than one link..
