You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

There is a bug about Eclipse and spring-boot-starter-parent 2.1.5

"if the maven packaging attribute is war then no problem.The problem is in jar type." So you can also fix this problem by changing packaging type.

<packaging>war</packaging>

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

You can add some code like this

ListView.builder{
   shrinkWrap: true,
}

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

Look for an installation subdirectory, likely named eclipse. Under that subdirectory, if you see files like eclipse.ini, icon.xpm and subdirectories like plugins and dropins, remove the subdirectory parent (the one named eclipse).

That will remove your installation except for anything you've set up yourself (like workspaces, projects, etc.).

Use org.springframework.web.servlet.config.annotation.WebMvcConfigurer

IDE: Eclipse Oxygen.3

To temporarily correct the problem do the following:

Project menu > Properties > Java Compiler > Compiler compliance level > 1.8

A permanent fix likely involves installing JDK 9.

FYI 1.8 is what Java 8 is called.

Side bar

I recently returned to Java after a foray into C# (a breath of fresh air) and installed Eclipse Oxygen onto a clean system that had never had Java installed on it before. This default everything with a brand new install of Eclipse Oxygen yet somehow or other Eclipse can't get its own parameters to match the jdk that's installed. This is the second project I created and the second time I ran into this headache. Time to go back to C#?

If you have multiple Java versions installed on your Mac, here's a quick way to switch the default version using Terminal. In this example, I am going to switch Java 10 to Java 8.

$ java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    10.0.1, x86_64: "Java SE 10.0.1"    /Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home
    1.8.0_171, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home

/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home

Then, in your .bash_profile add the following.

# Java 8
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home

Now if you try java -version again, you should see the version you want.

$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

I had a similar problem quite recently. In my case:

1. I downloaded an artifact from some less popular Maven repo

2. This repo dissappeared over this year

3. Now builds fail, even if I have this artifact and its pom.xml in my local repo

Workaround:

delete _remote.repositories file in your local repo, where this artifact resides. Now the project builds.

_{In general, to set a video's FPS to 24, almost always you can do:}

With Audio and without re-encoding:

# Extract video stream
ffmpeg -y -i input_video.mp4 -c copy -f h264 output_raw_bitstream.h264
# Extract audio stream
ffmpeg -y -i input_video.mp4 -vn -acodec copy output_audio.aac
# Remux with new FPS 
ffmpeg -y -r 24 -i output_raw_bitstream.h264 -i output-audio.aac -c copy output.mp4

If you want to find the video format (H264 in this case), you can use FFprobe, like this

ffprobe -loglevel error -select_streams v -show_entries stream=codec_name -of default=nw=1:nk=1 input_video.mp4

which will output:

h264

Read more in How can I analyze file and detect if the file is in H.264 video format?

With re-encoding:

ffmpeg -y -i input_video.mp4 -vf -r 24 output.mp4

in my case it was unused parameter in room persistence function in DAO class

I was facing the same issue and with some hint from @tadtab 's answer, I was able to figure out a solution for the same problem in my project.

Steps:

1->Follow the steps mentioned in @tadtab's answers.

2->Right Click on the project->Click on Properties->Search for Deployment Assembly.

3->Search whether your folder exists on the screen. (If not, add it).

4->On the screen you will find a 'Deploy Path' column corresponding to your source folder. Copy that path. In my case, it was /views.

5->So basically, in the setPrefix() method, we should have the path at the time of deployment. Earlier I was just using /views in the setPrefix() method, so I was getting the same error. But after, it worked well.

@Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();

        resolver.setPrefix("/WEB-INF/classes/");
        resolver.setSuffix(".jsp");

        resolver.setExposeContextBeansAsAttributes(true);
        return resolver;

    }

The same should be applicable to XML configuration also.

Is there a reason you couldn't select your results and right click and choose Advanced Copy -> Advanced Copy? I'm on a Mac and this is how I always copy results to the clipboard for pasting.

If you use any() when mocking, you have to relpace @RunWith(MockitoJUnitRunner.class) with @RunWith(MockitoJUnitRunner.Silent.class).

I am not able to run my own build on the other suggestions here. I even tried different versions of maven-compiler-plugin: 3.1, 3.7.0, etc.

I made it work adding this:

<testSourceDirectory>/src/test/java</testSourceDirectory>

I tried this approach because it seems like the /src/test/java directory is considered a java class that is why it is compiled the same time as /src/test/java. So my hunch were right in my case.

Maybe it is to others too, so just try this one.

If you are sending alphanumeric data try changing

'Content-Type': 'multipart/form-data'

to

'Content-Type': 'application/x-www-form-urlencoded'

If you are sending non-alphanumeric data try to remove 'Content-Type' at all.

If it still does not work, consider trying request-promise (at least to test whether it is really axios problem or not)

You can use the official Slider in the Material Components Library.

Use the app:trackHeight="xxdp" (default value is 4dp) to change the height of the track bar.

Also use these attributes to customize the colors:

• app:activeTrackColor: the active track color
• app:inactiveTrackColor: the inactive track color
• app:thumbColor: to fill the thumb

Something like:

    <com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:activeTrackColor="#ffd400"
        app:inactiveTrackColor="#e7e7e7"
        app:thumbColor="#ffb300"
        app:trackHeight="12dp"
        .../>

It requires the version 1.2.0 of the library.

If you use JDK 1.8.0_201 or latest try it with older JDK.

I have same issue with JDK1.8.0_201, however it works with JDK1.8.0_101 without any code change.

I can tell you for Windows.

1. Install Java Extension Pack and Code Runner Extension from VS Code Extensions.

2. Edit your java home location in VS Code settings, "java.home": "C:\\Program Files\\Java\\jdk-9.0.4".

3. Check if javac is recognized in VS Code internal terminal. If this check fails, try opening VS Code as administrator.

4. Create a simple Java program in Main.java file as:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");     
    }
}

Note: Do not add package in your main class.

5. Right click anywhere on the java file and select run code.

6. Check the output in the console.

Done, hope this helps.

Use this simple inline onClick function on a button if you want to programatically write data to the clipboard.

onClick={() => {navigator.clipboard.writeText(this.state.textToCopy)}}

If you want to know all the shortcut in intellij hit Ctrl + J. This shows all the shortcuts. For System.out.println() type sout and press Tab.

If you are using debug configuration for maven, use the command

clean install

And skip all the tests.

Paul's answer is very good and it is actually how Kafka & Zk work together from a broker point of view.

I would say that another easy option to check if a Kafka server is running is to create a simple KafkaConsumer pointing to the cluste and try some action, for example, listTopics(). If kafka server is not running, you will get a TimeoutException and then you can use a try-catch sentence.

  def validateKafkaConnection(kafkaParams : mutable.Map[String, Object]) : Unit = {
    val props = new Properties()
    props.put("bootstrap.servers", kafkaParams.get("bootstrap.servers").get.toString)
    props.put("group.id", kafkaParams.get("group.id").get.toString)
    props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer")
    props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer")
    val simpleConsumer = new KafkaConsumer[String, String](props)
    simpleConsumer.listTopics()
  }

Your code was compiled with Java 8.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.

Hope this helps...

Just a simple solution is here...it worked for me:

1. Clean Project
2. Rebuild project
3. Sync project with gradle file

I had also faced the same issue and it got resolved by changing the version from 3.2.0 to 2.6 as shown in below pom.xml snippet

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <warSourceDirectory>src/main/webapp</warSourceDirectory>
        <warName>Spring4MVC</warName>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>

Command line only without sdkmanager (for advanced users / CI):

You can find the download links for all individual packages, including various revisions, in the repository XML file: https://dl.google.com/android/repository/repository-12.xml

(where 12 is the version of the repository index and will increase in the future).

All <sdk:url> values are relative to https://dl.google.com/android/repository, so

<sdk:url>platform-27_r03.zip</sdk:url>

can be downloaded at https://dl.google.com/android/repository/platform-27_r03.zip

Similar summary XML files exist for system images as well:

• (default) https://dl.google.com/android/repository/sys-img/android/sys-img.xml
• (google_apis) https://dl.google.com/android/repository/sys-img/google_apis/sys-img.xml

**In my case problem solved with Instant Run DISABLE **

You have to patch catalina.jar, as this is version number the WTP adapter looks at. It's a quite useless check, and the adapter should allow you to start the server anyway, but nobody has though of that yet.

For years and with every version of Tomcat this is always a problem.

To patch you can do the following:

• cd [tomcat or tomee home]/lib
• mkdir catalina
• cd catalina/
• unzip ../catalina.jar
• vim org/apache/catalina/util/ServerInfo.properties

Make sure it looks like the following (the version numbers all need to start with 8.0):

server.info=Apache Tomcat/8.0.0
server.number=8.0.0
server.built=May 11 2016 21:49:07 UTC

Then:

• jar uf ../catalina.jar org/apache/catalina/util/ServerInfo.properties
• cd ..
• rm -rf catalina

I am using Google appengine java sdk and was facing similar issue. I had to add

<runtime>java8</runtime>

in appengine-web.xml file to make it work.

This solution add the deselection of the text after the copy to the clipboard:

function copyDivToClipboard(elem) {
    var range = document.createRange();
    range.selectNode(document.getElementById(elem));
    window.getSelection().removeAllRanges();
    window.getSelection().addRange(range);
    document.execCommand("copy");
    window.getSelection().removeAllRanges();
}

The normal layout for a maven multi module project is:

parent
+-- pom.xml
+-- module
    +-- pom.xml

Check that you use this layout.

Additionally:

1. the relativePath looks strange. Instead of '..'

   <relativePath>..</relativePath>
   

   try '../' instead:

   <relativePath>../</relativePath>
   

   You can also remove relativePath if you use the standard layout. This is what I always do, and on the command line I can build as well the parent (and all modules) or only a single module.

2. The module path may be wrong. In the parent you define the module as:

   <module>junitcategorizer.cutdetection</module>
   

   You must specify the name of the folder of the child module, not an artifact identifier. If junitcategorizer.cutdetection is not the name of the folder than change it accordingly.

Hope that helps..

EDIT have a look at the other post, I answered there.

I know this is an old issue but I just had to do this for a project at work, and I am very surprised that nobody has thought of this solution yet: Just open the .pdf with Microsoft word.

The code is a lot easier to work with when you are trying to extract data from a .docx because it opens in Microsoft Word. Excel and Word play well together because they are both Microsoft programs. In my case, the file of question had to be a .pdf file. Here's the solution I came up with:

1. Choose the default program to open .pdf files to be Microsoft Word
2. The first time you open a .pdf file with word, a dialogue box pops up claiming word will need to convert the .pdf into a .docx file. Click the check box in the bottom left stating "do not show this message again" and then click OK.
3. Create a macro that extracts data from a .docx file. I used MikeD's Code as a resource for this.
4. Tinker around with the MoveDown, MoveRight, and Find.Execute methods to fit the need of your task.

Yes you could just convert the .pdf file to a .docx file but this is a much simpler solution in my opinion.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:

import seaborn as sns
tips = sns.load_dataset("tips")

b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()

, which results in this:

To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.

NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.

Like Abob said:

Eclipse doesn't consult the JAVA_HOME variable

You should specify where Eclipse should find your JDK in the file eclipse.ini. Specifically, the following parameter (note that it is 2 separate lines in the ini file):

-vm
C:\Java\JDK\1.8\bin\javaw.exe

or wherever your javaw.exe happens to be.

Note: The format of the ini file is very particular; make sure to consult https://wiki.eclipse.org/Eclipse.ini to ensure you get it exactly right.

I have also faced the similar problem with the following details Java 1.8.0_121, Spark spark-1.6.1-bin-hadoop2.6, Windows 10 and Eclipse Oxygen.When I ran my WordCount.java in Eclipse using HADOOP_HOME as a system variable as mentioned in the previous post, it did not work, what worked for me is -

System.setProperty("hadoop.home.dir", "PATH/TO/THE/DIR");

PATH/TO/THE/DIR/bin=winutils.exe whether you run within Eclipse as a Java application or by spark-submit from cmd using

spark-submit --class groupid.artifactid.classname --master local[2] /path to the jar file created using maven /path to a demo test file /path to output directory command

Example: Go to the bin location of Spark/home/location/bin and execute the spark-submit as mentioned,

D:\BigData\spark-2.3.0-bin-hadoop2.7\bin>spark-submit --class com.bigdata.abdus.sparkdemo.WordCount --master local[1] D:\BigData\spark-quickstart\target\spark-quickstart-0.0.1-SNAPSHOT.jar D:\BigData\spark-quickstart\wordcount.txt

Here are steps:

• download 1.8 JDK from this site
• install it
• copy the jre folder & paste it in "C:\Program Files (x86)\EclipseNeon\"
• rename the folder to "jre"
• start the eclipse again

It should work.

PuTTY can't find where your X server is, because you didn't tell it. (ssh on Linux doesn't have this problem because it runs under X so it just uses that one.) Fill in the blank box after "X display location" with your Xming server's address.

Alternatively, try MobaXterm. It has an X server builtin.

If your android SDK path is given and still you facing this issue then it might because your android studio not synced well, even you have clicked on "Sync now" link.

So for re sync it go to app gradle file and make any change or just give a space and now sync again. It will work perfectly.

Since it is easy to tackle with Command Prompt. Open the CMD and type following.

netstat -aon | find "8080"

If a process uses above port, it should return something output like this.

TCP    xxx.xx.xx.xx:8080      xx.xx.xx.xxx:443      ESTABLISHED     2222

The last column value (2222) is referred to the Process ID (PID).

Just KILL it as follows.

taskkill /F /PID 2222

Now you can start your server.

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

sudo apt-get install openjfx

At the time of writing, setting display:none on the element didn't work for me. Setting the element's width and height to 0 did not work either. So the element has to be at least 1px in width for this to work.

The following example worked in Chrome and Firefox:

    const str = 'Copy me';
    const el = document.createElement("input");
    // Does not work:
    // dummy.style.display = "none";
    el.style.height = '0px';
    // Does not work:
    // el.style.width = '0px';
    el.style.width = '1px';
    document.body.appendChild(el);
    el.value = str;
    el.select();
    document.execCommand("copy");
    document.body.removeChild(el);

I'd like to add that I can see why the browsers are trying to prevent this hackish approach. It's better to openly show the content you are going copy into the user's browser. But sometimes there are design requirements, we can't change.

UPDATE: installation without root privileges below

I advise you to not install packages manually on ubuntu system if there is already a (semi-official) repository able to solve your problem. Further, use Oracle JDK for development, just to avoid (very sporadic) compatibility issues (i've tried many years ago, it's surely better now).

Add the webupd8 repo to your system:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Install your preferred version of jdk (versions from java-6 to java-9 available):

sudo apt-get install oracle-java8-installer

You can also install multiple version of jdk, mixing openjdk and oracle versions. Then you can use the command update-java-alternatives to switch between installed version:

# list available jdk
update-java-alternatives --list

# use jdk7
sudo update-java-alternatives --set java-7-oracle

# use jdk8
sudo update-java-alternatives --set java-8-oracle

Requirements

If you get add-apt-repository: command not found be sure to have software-properties-common installed:

sudo apt-get install software-properties-common

If you're using an older version Ubuntu:

sudo apt-get install python-software-properties

JDK installation without root privileges

If you haven't administrator rights on your target machine your simplest bet is to use sdkman to install the zulu certified openjdk:

curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java

NOTE: sdkman allow to install also the official Oracle JDK, although it's not a the default option. View available versions with:

sdk ls java

Install the chosen version with:

sdk install java <version>

For example:

sdk install java 9.0.1-oracle

Glossary of commands

• sudo <command> [command_arguments]: execute a command with the superuser privilege.

• add-apt-repository <PPA_id>: Ubuntu (just like every Debian derivatives and generally speaking every Linux distribution) has a main repository of packages that handle things like package dependencies and updating. In Ubuntu is possible to extend the main repository using a PPA (Personal Package Archive) that usually contains packages not available in the system (just like oracle jdk) or updated versions of available ones (example: LibreOffice 5 in LTS is available only through this PPA).

• apt-get [install|update|upgrade|purge|...]: it's "the" command-line package handler used to manipulate the state of every repository on the system (installing / updating / upgrading can be viewed as an alteration of the repository current state).

In our case: with the command sudo add-apt-repository ppa:webupd8team/java we inform the system that the next repository update must retrieve packages information also from webupd8 repo.

With sudo apt-get update we actually update the system repository (all this operations requires superuser privileges, so we prepend sudo to the commands).

sudo apt-get install oracle-java8-installer

• update-java-alternatives (a specific java version of update-alternatives): in Ubuntu several packages provides the same functionality (browse the internet, compile mails, edit a text file or provides java/javac executables...). To allows the system to choose the user favourites tool given a specific task a mechanism using symlinks under /etc/alternatives/ is used. Try to update the jdk as indicated above (switch between java 7 and java 8) and view how change the output of this command:

  ls -l /etc/alternatives/java*

In our case: sudo update-java-alternatives --set java-8-oracle update symlinks under /etc/alternatives to point to java-8-oracle executables.

Extras:

• man <command>: start using man to read a really well written and detailed help on (almost) every shell command and its options (every command i mention in this little answer has a man page, try man update-java-alternatives).

• apt-cache search <search_key>: query the APT cache to search for a package related with the search_key provided (can be the package name or some word in package description).

• apt-cache show <package>: provides APT information for a specific package (package version, installed or not, description).

According to the Apache site this is the Gradle dependency you need to include, if you use Android API 23 or newer:

dependencies {
    compile group: 'cz.msebera.android' , name: 'httpclient', version: '4.4.1.1'
}

Source: https://hc.apache.org/httpcomponents-client-4.5.x/android-port.html

As others have already mentioned your compile sdk version must match your support library's major version. This is however, also relevant for subprojects should you have any.

In case you do, you can set your subprojects compile sdk versions with the following script:

subprojects { subproject ->
afterEvaluate{
    if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
        android {
            compileSdkVersion rootProject.ext.compileSdkVersion
            buildToolsVersion rootProject.ext.buildToolsVersion
        }
      }
   }
}

Add this script in your root build.gradle file.

This is a maven error. It says that it is expecting a web.xml file in your project because it is a web application, as indicated by <packaging>war</packaging>. However, for recent web applications a web.xml file is totally optional. Maven needs to catch up to this convention. Add this to your maven pom.xml to let maven catch up and you don't need to add a useless web.xml to your project:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.6</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>

This is a better solution than adding an empty web.xml because this way your final product stays clean, your are just changing your build parameters.

For more current versions of maven you can also use the shorter version:

<properties>
    <failOnMissingWebXml>false</failOnMissingWebXml>
</properties>

This is a general answer for future visitors. The various ways to update the adapter data are explained. The process includes two main steps every time:

1. Update the data set
2. Notify the adapter of the change

#Insert single item

Add "Pig" at index 2.

String item = "Pig";
int insertIndex = 2;
data.add(insertIndex, item);
adapter.notifyItemInserted(insertIndex);

#Insert multiple items

Insert three more animals at index 2.

ArrayList<String> items = new ArrayList<>();
items.add("Pig");
items.add("Chicken");
items.add("Dog");
int insertIndex = 2;
data.addAll(insertIndex, items);
adapter.notifyItemRangeInserted(insertIndex, items.size());

#Remove a single item

Remove "Pig" from the list.

int removeIndex = 2;
data.remove(removeIndex);
adapter.notifyItemRemoved(removeIndex);

#Remove multiple items

Remove "Camel" and "Sheep" from the list.

int startIndex = 2; // inclusive
int endIndex = 4;   // exclusive
int count = endIndex - startIndex; // 2 items will be removed
data.subList(startIndex, endIndex).clear();
adapter.notifyItemRangeRemoved(startIndex, count);

#Remove all items

Clear the whole list.

data.clear();
adapter.notifyDataSetChanged();

#Replace old list with the new list

Clear the old list then add a new one.

// clear old list
data.clear();

// add new list
ArrayList<String> newList = new ArrayList<>();
newList.add("Lion");
newList.add("Wolf");
newList.add("Bear");
data.addAll(newList);

// notify adapter
adapter.notifyDataSetChanged();

The adapter has a reference to data, so it is important that I didn't set data to a new object. Instead, I cleared the old items from data and then added the new ones.

#Update single item

Change the "Sheep" item so that it says "I like sheep."

String newValue = "I like sheep.";
int updateIndex = 3;
data.set(updateIndex, newValue);
adapter.notifyItemChanged(updateIndex);

#Move single item

Move "Sheep" from position 3 to position 1.

int fromPosition = 3;
int toPosition = 1;

// update data array
String item = data.get(fromPosition);
data.remove(fromPosition);
data.add(toPosition, item);

// notify adapter
adapter.notifyItemMoved(fromPosition, toPosition);

#Notes

• If you use notifyDataSetChanged(), then no animation will be performed. This can also be an expensive operation, so it is not recommended to use notifyDataSetChanged() if you are only updating a single item or a range of items.
• Check out DiffUtil if you are making large or complex changes to a list.

SpringBoot developers recommend to locate your main application class in a root package above other classes. Using a root package also allows the @ComponentScan annotation to be used without needing to specify a basePackage attribute. Detailed info But be sure that the custom root package exists.

Not all at once. But you can press

Alt + Enter

People assume it only works when you are at the particular item. But it actually works for "next missing type". So if you keep pressing Alt + Enter, IDEA fixes one after another until all are fixed.

We want to automatically pick property file based upon mentioned the profile name in spring.profiles.active and the path in -Dspring.config.location

application-dev.properties

If we are running jar in Unix OS then we have to use / at the end of -Dspring.config.location otherwise it will give below error.

Error :: java.lang.IllegalStateException: File extension of config file location 'file:/home/xyz/projectName/cfg' is not known to any PropertySourceLoader. If the location is meant to reference a directory, it must end in '/'

Example

java -Dspring.profiles.active=dev -Dspring.config.location=/home/xyz/projectName/cfg/ -jar /home/xyz/project/abc.jar

or

java -jar /home/xyz/project/abc.jar --spring.profiles.active=dev --spring.config.location=/home/xyz/projectName/cfg/

I know it's an old question and it has been solved already but for me the Tomcat conf/tomcat-users.xml file was created with a different encoding from the rest of the configuration files. The first line of that file looked like this:

<?xml version='1.0' encoding='cp65001'?>

All I had to do to solve the issue was change that line for:

<?xml version="1.0" encoding="UTF-8"?>

And voila.

I have no idea what 'cp65001' means or why it was created like that.

Maybe this will help other users facing the same issue.

My Android Studio was not only slow in general use, but also when building.

Here's what I did:

1. Uninstalled Android Studio (Don't delete, uninstall it and check delete the SDK too). Then delete Android folders located in C:\Users\\ folder namely: .android, AndroidStudioX.X
2. Uninstall the SDKs via the SDK manager, remove everything ( If there is lef SDK folder, delete them )
3. Download and Reinstall the latest build for Android Studio (v2.1.2 as of this writing); Install only the SDK/Emulators you need;

It's fast now.

My Story before that:

My laptop sports an Intel Core i7-3612QM and 8gig of ram. When I builded, all the 4 cores/8 threads were on 100% usage. My entire system froze until the ~10 minute wass done. Gradle took me like ~10 unproductive minutes of slow down. This is very annoying. I am using Android Studio since 1.4. There were also tremendous slow down when I copy paste code to and from, selecting menus, right-click context menus, editing manifest, editing gradle files, opening layout files, rendering in the UI Editor, etc. Its was very unusable most of the time.

Due to frustration, I did the above steps. Its fast now. Very usable just as before. I build for only ~20 seconds compare to ~10minutes before that. Also, Android Studio eats about 6gig with emulator and browser with lots of tab open, unlike before its hovering on 98% RAM usage. Not just that, I even saved 45 gigs of space for whatever reason. I only use couple of SDKs and Emulators when I checked the Android SDK folder, it occupies 45gig of space! I think the IDE is having a hard time accessing/IO on my SDK folder.

If you've tried other given solutions and still experiencing the same issue, it may be time to remove Android IDE/SDKs altogether and start anew (it might take you sometime to setup that newly, but its worth it. Considering I've been suffering this sluggishness for months and cost me my productivity).

I really guess that this might be caused by cumulative patches that has been done since then. Or the 45 gig SDK folder on my poorly defragmented drive. I don't know and I could be wrong.

Thank you! HTH

They are project files, that hold the module information and meta data.

Just add *.iml to .gitignore.

In Android Studio: Press CTRL + F9 to rebuild your project. The missing *.iml files will be generated.

This is what worked for me in IntelliJIdea:

Go to File -> Build, Execution, Deployment -> Build Tools -> Maven -> Repositories

Check that there are two repositories:

https://repo.maven.apache.org/maven2  (Remote)
C:/Users/_user_/.m2/repository   (Local)

And then click on Update for both repos. The update of remote repository will take a while, but in the end click on OK and that's all.

In my case I removed these two

If you are using datetimepicker make sure you include the right CSS and JS files. datetimepicker uses(Take note of their names);

https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/css/bootstrap-datetimepicker.css

and

On the above question asked by @mindfreak,The main problem is due to the imported files.

WARNING! This is an incorrect solution. layers are added infinitely in the drawRect method (every time the view is drawn). You should NEVER add layers in the drawRect method. Use layoutSubview instead.

You can draw a circle with this (Swift 3.0+):

let circlePath = UIBezierPath(arcCenter: CGPoint(x: 100, y: 100), radius: CGFloat(20), startAngle: CGFloat(0), endAngle: CGFloat(Double.pi * 2), clockwise: true)
    
let shapeLayer = CAShapeLayer()
shapeLayer.path = circlePath.cgPath
    
// Change the fill color
shapeLayer.fillColor = UIColor.clear.cgColor
// You can change the stroke color
shapeLayer.strokeColor = UIColor.red.cgColor
// You can change the line width
shapeLayer.lineWidth = 3.0
    
view.layer.addSublayer(shapeLayer)

With the code you have posted you are cropping the corners of the UIView, not adding a circle to the view.

Here's a full example of using that method:

/// A special UIView displayed as a ring of color
class Ring: UIView {
    override func drawRect(rect: CGRect) {
        drawRingFittingInsideView()
    }
    
    internal func drawRingFittingInsideView() -> () {
        let halfSize:CGFloat = min( bounds.size.width/2, bounds.size.height/2)
        let desiredLineWidth:CGFloat = 1 // your desired value
            
        let circlePath = UIBezierPath(
                arcCenter: CGPoint(x:halfSize,y:halfSize),
                radius: CGFloat( halfSize - (desiredLineWidth/2) ),
                startAngle: CGFloat(0),
                endAngle:CGFloat(M_PI * 2),
                clockwise: true)
    
         let shapeLayer = CAShapeLayer()
         shapeLayer.path = circlePath.CGPath
            
         shapeLayer.fillColor = UIColor.clearColor().CGColor
         shapeLayer.strokeColor = UIColor.redColor().CGColor
         shapeLayer.lineWidth = desiredLineWidth
    
         layer.addSublayer(shapeLayer)
     }
}

Note, however there's an incredibly handy call:

let circlePath = UIBezierPath(ovalInRect: rect)

which does all the work of making the path. (Don't forget to inset it for the line thickness, which is also incredibly easy with CGRectInset.)

internal func drawRingFittingInsideView(rect: CGRect) {
    let desiredLineWidth:CGFloat = 4    // Your desired value
    let hw:CGFloat = desiredLineWidth/2
    
    let circlePath = UIBezierPath(ovalInRect: CGRectInset(rect,hw,hw))
    let shapeLayer = CAShapeLayer()
    shapeLayer.path = circlePath.CGPath
    shapeLayer.fillColor = UIColor.clearColor().CGColor
    shapeLayer.strokeColor = UIColor.redColor().CGColor
    shapeLayer.lineWidth = desiredLineWidth
    layer.addSublayer(shapeLayer)
}

In practice these days in Swift, you would certainly use @IBDesignable and @IBInspectable. Using these you can actually see and change the rendering, in Storyboard!

As you can see, it actually adds new features to the Inspector on the Storyboard, which you can change on the Storyboard:

/// A dot with a border, which you can control completely in Storyboard
@IBDesignable class Dot: UIView {

    @IBInspectable var mainColor: UIColor = UIColor.blueColor() {
        didSet { 
             print("mainColor was set here")
        }
    }

    @IBInspectable var ringColor: UIColor = UIColor.orangeColor() {
         didSet {
             print("bColor was set here") 
        }
    }

    @IBInspectable var ringThickness: CGFloat = 4 {
        didSet { 
            print("ringThickness was set here")
        }
    }
    
    @IBInspectable var isSelected: Bool = true
    
    override func drawRect(rect: CGRect) {
        let dotPath = UIBezierPath(ovalInRect:rect)
        let shapeLayer = CAShapeLayer()
        shapeLayer.path = dotPath.CGPath
        shapeLayer.fillColor = mainColor.CGColor
        layer.addSublayer(shapeLayer)
        
        if (isSelected) { 
            drawRingFittingInsideView(rect)
        }
    }
    
    internal func drawRingFittingInsideView(rect: CGRect) {
        let hw:CGFloat = ringThickness/2
        let circlePath = UIBezierPath(ovalInRect: CGRectInset(rect,hw,hw) )
        
        let shapeLayer = CAShapeLayer()
        shapeLayer.path = circlePath.CGPath
        shapeLayer.fillColor = UIColor.clearColor().CGColor
        shapeLayer.strokeColor = ringColor.CGColor
        shapeLayer.lineWidth = ringThickness
        layer.addSublayer(shapeLayer)
    }
}

Finally, note that if you have a UIView (which is square, and which you set to say red in Storyboard) and you simply want to turn it in to a red circle, you can just do the following:

// Makes a UIView into a circular dot of color
class Dot: UIView {
    override func layoutSubviews() {
        layer.cornerRadius = bounds.size.width/2
    }
}

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Let me know if you have a problem.

As of API 28 at least:

1. Open Settings app in emulator
2. Search for "Storage" select search result for it
3. Select Photos & Videos in Storage
4. Select Images
5. Drag an image onto the emulator, it won't immediately show up
6. From the AVD Manager in Android Studio, cold boot the emulator

The photos you've dragged in are now available.

To add an element to an array you need to use the format:

array[index] = element;

Where array is the array you declared, index is the position where the element will be stored, and element is the item you want to store in the array.

In your code, you'd want to do something like this:

int[] num = new int[args.length];
for (int i = 0; i < args.length; i++) {
    int neki = Integer.parseInt(args[i]);
    num[i] = neki;
}

The add() method is available for Collections like List and Set. You could use it if you were using an ArrayList (see the documentation), for example:

List<Integer> num = new ArrayList<>();
for (String s : args) {
    int neki = Integer.parseInt(s);
    num.add(neki);
}

If you have USB-Debugging/ADB enabled on your phone and your PC is authorized for debugging on your phone then you can try one of the follwing tools:

scrcpy

scrcpy connects over adb to your device and executes a temporary app to stream the contents of your screen to your PC and you're able to remote control your device. It works on GNU/Linux, Windows and macOS.

Vysor

Vysor is a chrome web app that connects to your device via adb and installs a companion app to stream your screen content to the PC. You can then remote control your device with your mouse.

MonkeyRemote

MonkeyRemote is a remote control tool written by myself before I found Vysor. It also connects through adb and lets you control your device by mouse but in contrast to Vysor, the streamed screen content updates very slow (~1 frame per second). The upside is that there is no need for a companion app to be installed.

That is a problem of security protocol. I am using TLSv1 but the host accept only TLSv1.1 and TLSv1.2 then I changed the protocol in Java with the instruction below:

System.setProperty("https.protocols", "TLSv1.1");

I was facing the same problem and solved it using the below steps:

Add this in your app's build.gradle

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

Use namespace:

xmlns:app="http://schemas.android.com/apk/res-auto"

Then use:

app:srcCompat="@drawable/your_vector_drawable_here"

Just make sure build with correct web.xml configuration.I have update web.xml with tomcat configuration and it worked for me. Sample :-

<?xml version="1.0" encoding="UTF-8"?>_x000D_
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"_x000D_

Value cannot be null. Parameter name: source

Above error comes in situation when you are querying the collection which is null.

For demonstration below code will result in such an exception.

Console.WriteLine("Hello World");
IEnumerable<int> list = null;
list.Where(d => d ==4).FirstOrDefault();

Here is the output of the above code.

Hello World Run-time exception (line 11): Value cannot be null. Parameter name: source

Stack Trace:

[System.ArgumentNullException: Value cannot be null. Parameter name: source] at Program.Main(): line 11

In your case ListMetadataKor is null. Here is the fiddle if you want to play around.

Use spring-boot:run command to start spring boot application:

Precondition: 1. Add following property to pom.xml

<property>    
<start-class>com.package.name.YourApplicationMainClass</start-class>
</property>

2. Build your project

Then configure maven command with spring-boot:run.

Navigation:

Right Click Project | Run As | Run Configuration... | Add new Maven Configuration with command spring-boot:run

I wrote more universal solution based on @Fer answer.

It also should work with flavor and build type based configuration of applicationId, versionName, versionCode.

In the build.gradle:

android {
    ...
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def appId = variant.applicationId
            def versionName = variant.versionName
            def versionCode = variant.versionCode
            def flavorName = variant.flavorName // e. g. free
            def buildType = variant.buildType // e. g. debug
            def variantName = variant.name // e. g. freeDebug

            def apkName = appId + '_' + variantName + '_' + versionName + '_' + versionCode + '.apk';
            output.outputFile = new File(output.outputFile.parentFile, apkName)
        }
    }
}

Example apk name: com.example.app_freeDebug_1.0_1.apk

For more information about variant variable see ApkVariant and BaseVariant interfaces definition.

how to retrieve keystore password

You cannot retrieve the password. If you forgot it, you are doomed.

how to retrieve key alias

$ keytool -list -v -keystore <store>

But you need keystore password for this first.

EDIT

What I don't remember is the 'Key Password'

No password can be restored. If you forgot key password for good then you are doomed too and there's no other way than trying harder to recall it. There's no password reset thing nor anything like that.

Be aware that if you forgot your password for good then you will issue no further updates to your app (docs):

Warning: Keep your keystore and private key in a safe and secure place, and ensure that you have secure backups of them. If you publish an app to Google Play and then lose the key with which you signed your app, you will not be able to publish any updates to your app, since you must always sign all versions of your app with the same key.

To answer your question posted in the title of this topic...

Step 1--> Right Click on Java Project, Select the option "Properties"

Step 2--> Select "Java Build Path" from the left side menu, make sure you are on "Source" tab, click "Add Folder"

Step 3--> Click the option "Create New Folder..." available at the bottom of the window

Step 4--> Enter the name of the new folder as "resources" and then click "Finish"

Step 5--> Now you'll be able to see the newly created folder "resources" under your java project, Click "Ok", again Click "Ok"

Final Step --> Now you should be able to see the new folder "resources" under your java project

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

Another way of stopping logs completely is:

    import org.apache.log4j.Appender;
    import org.apache.log4j.BasicConfigurator;
    import org.apache.log4j.varia.NullAppender;

    public class SomeClass {

        public static void main(String[] args) {
            Appender nullAppender = new NullAppender();
            BasicConfigurator.configure(nullAppender);

            {...more code here...}

        }
    }

This worked for me. An NullAppender is

An Appender that ignores log events. (https://logging.apache.org/log4j/2.x/log4j-core/apidocs/org/apache/logging/log4j/core/appender/NullAppender.html)

Yes, the list of keyboard shortcuts for Android Studio is at https://developer.android.com/studio/intro/keyboard-shortcuts.html.

Here are a few that I know.

Check :File ->Settings ->Keymap -> <Choose Eclipse from Keymaps dropdown> or

Add unimplemented methods: CTRL + I

Override methods: CTRL + O

Format code: CTRL + ALT + L

Show project: ALT + 1

Show logcat: ALT + 6

Hide project - logcat: SHIFT + ESC

Build: CTRL + F9

Build and Run: CTRL + F10

Expand all: CTRL + SHIFT + NumPad +

Collapse all: CTRL + SHIFT + NumPad -

Find and replace: CTRL + R

Find: CTRL + F

In case I'm missing any shortcut that you need you can ask here and for more check implink!! or link!!:)

For getting SHA1 for a production keystore:

1. Build --> Generate Signed APK...

2. Create keystore with password and follow the steps

3. Go to your Mac/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin and drag the bin folder to the terminal after cd command to point at it so you can use the keytool tool. So, in terminal write cd (drag bin here) then press enter.

4. Then, copy and paste this in the terminal:

   keytool -exportcert -alias Your_keystore_AliasName -keystore /Users/Home/Development/AndroidStudioProjects/YoutubeApp/app/YoutubeApp_keystore.jks -list -v
   

   Erase my path and go where you stored your keystore and drag your keystone and drop it after -keystore in the command line so the path will get created.

   Also, erase Your_keystore_AliaseName to put your alias keystone name that you used when you created it.

5. Press Enter and enter the password :)

6. When you enter the password, the terminal won't show that it receives keyboard entries, but it actually does, so put the password and press Enter even if you don't see the password is typed out.

With Support Library 26.0 (and Android O) fonts can be loaded from resource easily with:

Typeface typeface = ResourcesCompat.getFont(Context context, int fontResourceId) 

Docs for the method.

More info can be found here.

Note: this is purely an IDEA/AS issue, gradlew clean | Build > Clean | Build > Rebuild will just waste your time.

Most of the solutions here are blind stabbings in the dark. Here's what I found to be the root cause:

1. Some of the .iml files may be missing (maybe because we deleted it), check if the module erroring has .iml.
2. If it is missing, check if .idea/modules.xml has an entry for that module

While syncing I noticed that IDEA/AS tries to put a new duplicate entry into .idea/modules.xml while there's already one. This duplicate entry is probably disposed of twice while the sync tries to reset the modules in memory.

Quick Solution: In order to make it work the easiest is to delete .idea/modules.xml along with the .iml files. Additionally may worth deleting .idea/modules/ folder if it exists. Restart Android Studio (no need to clear cache) and force a Gradle sync from Gradle view or toolbar to recreate the files.

Please add the following dependency http://mvnrepository.com/artifact/org.json/json/20080701

Remove any "Hard Coded" reference of your package name, from your manifest file.

(This is best practice even if you don't using productFlavors)

For example, if your manifest contains:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
<uses-permission android:name="com.yourpackage.name.permission.C2D_MESSAGE"/>

<permission
    android:name="com.yourpackage.name.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>
<permission
    android:name="com.yourpackage.name.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>

Changed it to:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>

<permission
    android:name="${applicationId}.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>
<permission
    android:name="${applicationId}.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>

Then, in your module gradle file, set your relevant applicationId:

signingConfigs {
    stage {
        storeFile file('keystore/stage.keystore')
        storePassword 'android'
        keyAlias 'androiddebugkey'
        keyPassword 'android'
    }
    production {
        storeFile file('keystore/playstore.keystore')
        storePassword store_password
        keyAlias key_alias
        keyPassword key_password
    }
}

productFlavors {
    staging {
        signingConfig signingConfigs.staging
        applicationId defaultConfig.applicationId + ".staging"
        versionName defaultConfig.versionName + "-staging"
    }

    production {
        signingConfig signingConfigs.production
    }
}

This is caused when java is updated. You have to delete in environement path : C:**ProgramData\Oracle\Java\javapath**

Adding the tomcat server in the server runtime will do the job :

Project Properties-> Java Build Path-> Add Library -> Select "Server Runtime" from the list-> Next->Select "Apache Tomcat"-> Finish

Try this (on the guest machine. i.e. the OS running in the Virtual box):

sudo adduser your-user vboxsf

Now reboot the OS running in the virtual box.

For Single valued associations, i.e.-One-to-One and Many-to-One:-
Default Lazy=proxy
Proxy lazy loading:- This implies a proxy object of your associated entity is loaded. This means that only the id connecting the two entities is loaded for the proxy object of associated entity.
Eg: A and B are two entities with Many to one association. ie: There may be multiple A's for every B. Every object of A will contain a reference of B.
`

public class A{
    int aid;
    //some other A parameters;
    B b;
}
public class B{
    int bid;
     //some other B parameters;
}

`
The relation A will contain columns(aid,bid,...other columns of entity A).
The relation B will contain columns(bid,...other columns of entity B)
Proxy implies when A is fetched, only id is fetched for B and stored into a proxy object of B which contains only id. Proxy object of B is a an object of a proxy-class which is a subclass of B with only minimal fields. Since bid is already part of relation A, it is not necessary to fire a query to get bid from the relation B. Other attributes of entity B are lazily loaded only when a field other than bid is accessed.

For Collections, i.e.-Many-to-Many and One-to-Many:-
Default Lazy=true


Please also note that the fetch strategy(select,join etc) can override lazy. ie: If lazy='true' and fetch='join', fetching of A will also fetch B or Bs(In case of collections). You can get the reason if you think about it.
Default fetch for single valued association is "join".
Default fetch for collections is "select". Please verify the last two lines. I have deduced that logically.

There also exists a 'JVM Debugger Memory View' found in the plugin repository, which could be useful.

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

This resolves it for me:

Go to (C:\users\%USERNAME%\AppData\Local\Android\sdk, generally).

Then go to Extras -> Intel -> Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe".

In case you get an error like "Intel virtualization technology (vt,vt-x) is not enabled", go to your BIOS settings and enable Hardware Virtualization.

Restart your studio

Now I return Object. I don't know better solution, but it works.

@RequestMapping(value="", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody ResponseEntity<Object> getAll() {
    List<Entity> entityList = entityManager.findAll();

    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return new ResponseEntity<Object>(entities, HttpStatus.OK);
}

From official documentation

Warning: Do not filter files with binary content like images! This will most likely result in corrupt output.

If you have both text files and binary files as resources it is recommended to have two separated folders. One folder src/main/resources (default) for the resources which are not filtered and another folder src/main/resources-filtered for the resources which are filtered.

<project>
  ...
  <build>
    ...
    <resources>
      <resource>
        <directory>src/main/resources-filtered</directory>
        <filtering>true</filtering>
      </resource>
      ...
    </resources>
    ...
  </build>
  ...
</project>

Now you can put those files into src/main/resources which should not filtered and the other files into src/main/resources-filtered.

As already mentioned filtering binary files like images,pdf`s etc. could result in corrupted output. To prevent such problems you can configure file extensions which will not being filtered.

Most certainly, You have in your directory files that cannot be filtered. So you have to specify the extensions that has not be filtered.

I was facing the same error while running command

pip install --upgrade pip

in a virtual venvironment (created with python -m venv venv).

using the --user flag fixed the problem for me

pip install --upgrade pip --user

If the problem not resolved use --user flag in a command prompt with admin rights.

In your Eclipse Preferences -> java -> Installed JREs -> Select the Java SE the jdk which you have on your machine and add the JDK

You should check the node's port, you could do it using head. These ports are not same. Example,

The web URL you can open is localhost:9200, but the node's port is 9300, so none of the configured nodes are available if you use the 9200 as the port.

I had the same problem with SSL and maven. My companies IT policy restricts me to make any changes to the computers configuration, so I copied the entire .m2 from my other computer and pasted it .m2 folder and it worked.

.m2 folder is usually found under c\user\admin

Firstly, we just CAN'T make the variable final as its state may be changing during the run of the program and our decisions within the inner class override may depend on its current state.

Secondly, good object-oriented programming practice suggests using only variables/constants that are vital to the class definition as class members. This means that if the variable we are referencing within the anonymous inner class override is just a utility variable, then it should not be listed amongst the class members.

But – as of Java 8 – we have a third option, described here :

https://docs.oracle.com/javase/tutorial/java/javaOO/localclasses.html

Starting in Java SE 8, if you declare the local class in a method, it can access the method's parameters.

So now we can simply put the code containing the new inner class & its method override into a private method whose parameters include the variable we call from inside the override. This static method is then called after the btnInsert declaration statement :-

 . . . .
 . . . .

 Statement statement = null;                                 

 . . . .
 . . . .

 Button btnInsert = new Button(shell, SWT.NONE);
 addMouseListener(Button btnInsert, Statement statement);    // Call new private method

 . . . 
 . . .
 . . . 

 private static void addMouseListener(Button btn, Statement st) // New private method giving access to statement 
 {
    btn.addMouseListener(new MouseAdapter() 
    {
      @Override
      public void mouseDown(MouseEvent e) 
      {
        String name = text.getText();
        String from = text_1.getText();
        String to = text_2.getText();
        String price = text_3.getText();
        String query = "INSERT INTO booking (name, fromst, tost,price) VALUES ('"+name+"', '"+from+"', '"+to+"', '"+price+"')";
        try 
        {
            st.executeUpdate(query);
        } 
        catch (SQLException e1) 
        {
            e1.printStackTrace();                                    // TODO Auto-generated catch block
        }
    }
  });
  return;
}

 . . . .
 . . . .
 . . . .

Make sure the "m" in main() is lowercase this would also cause java not to see your main method, I've done that several times unfortunately.

Just delete the ${user.home}/.m2/repository/org/apache/maven/archetypes to refresh all files needed, it worked fine to me!

I had also faced this problem. Those time I followed some steps like:

1. File > New > Import module > select your library_project. Then include 'library_project' will be added in settings.gradle file.

2. File > Project Structure > App > Dependencies Tab > select library_project. If library_project not displaying then, Click on + button then select your library_project.

3. Clean and build your project. The following lines will be added in your app module build.gradle (hint: this is not the one where classpath is defined).

 dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile project(':library_project')
 }

4. If these lines are not present, you must add them manually and clean and rebuild your project again (Ctrl + F9).

5. A folder named library_project will be created in your app folder.

6. If any icon or task merging error is created, go to AndroidManifest file and add <application tools:replace="icon,label,theme">

for German Layout (Deutsches Layout) the default is:

for line Comment: strg + Numpad(/)

for block Comment: strg+shift+Numpad(/)

In my case I had to put it in the bin folder of my project even the fact that my classpath is set to the src folder. I have no idea why, but it's worth a try.

In my case eclipse was using an old settings.xml file.

Go to Project-> right Click-> Select Properties -> project Facets -> modify the java version for your JDK version you are using.

If someone is having this issue only in your CI tool while running maven, what did the trick for me was to explicitly define the execution environment in your MANIFEST.MF.

In my case, I did this by inserting the following line in my OSGi bundle manifest file:

Bundle-RequiredExecutionEnvironment: JavaSE-1.8

I had the same problem, to resolve it, go windows -> preferences -> servers and select runtime environment, and now you will see a new window, in the upper right you will see a option: Download additional server adapter, click and install the glassfish server.

I used this with Amazon EC2 with 1 master and 2 slaves and Spark 1.2.1.

# Step 1. Change config file on the master node
nano /root/ephemeral-hdfs/conf/log4j.properties

# Before
hadoop.root.logger=INFO,console
# After
hadoop.root.logger=WARN,console

# Step 2. Replicate this change to slaves
~/spark-ec2/copy-dir /root/ephemeral-hdfs/conf/

Due to Oracle license restriction, there are no public repositories that provide ojdbc jar.

You need to download it and install in your local repository. Get jar from Oracle and install it in your local maven repository using

mvn install:install-file -Dfile={path/to/your/ojdbc.jar} -DgroupId=com.oracle 
-DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

If you are using ojdbc7, here is the link

For me the sdk version mentioned in build.gradle wasn't installed. Used SDK Manager to install the right SDK version and it worked

For me non of the answers worked I saw here worked. I guessed that having the CPU work extremely hard makes the computer hot. After I closed programs that consume large amounts of CPU (like chrome) and cooling down my laptop the problem disappeared.

For reference: I had the CPU on 96%-97% and Memory usage over 2,000,000K by a java.exe process (which was actually gradle related process).

1. Go to your project in the navigator, right click on properties.

2. Go to the Java Build Path tab on the left.

3. Go to the libraries tab on top.

4. Click add external jars.

5. Go to your ADT Bundle folder, go to sdk/extras/android/support/v7/appcompat/libs.

6. Select the file android-support-v7-appcompat.jar

7. Go to order and export and check the box next to your new jar.

8. Click ok.

First of all you should get JdK 8.

if you have Jdk installed.

you should set its path using cmd prompt or system variables.

sometimes it can happen that the path is not set due to which eclipse is unable to get the properties for jdk.

Installing latest ecipse luna can solve your problem.

i have indigo and luna. i can set 1.8 in luna but 1.7 in indigo.Eclipse luna

You can check the eclipse site. it says that the eclipse luna was certainly to associate the properties for jdk 8.

Cause you need to add jQuery library to your file:

jQuery UI is just an addon to jQuery which means that
first you need to include the jQuery library → and then the UI.

<script src="path/to/your/jquery.min.js"></script>
<script src="path/to/your/jquery.ui.min.js"></script>

When I had this error, it was because I didn't have my class in a package. Put your HelloWorld.java file in a "package" folder. You may have to create a new package folder:

Right click on the hello folder and select "New" > "Package". Then give it a name (e.g: com.example) and move your HelloWorld.java class into the package.

Please use the below formula

=Clean("1"&CHAR(9)&"SOME NOTES FOR LINE 1."&CHAR(9)&"2"&CHAR(9)&"SOME NOTES FOR LINE 2.")

and you will get what you want ;-)

There are two setting.xml in windows.

• %MAVEN_HOME%\conf\
• %userprofile%\.m2\

If %userprofile%\.m2\setting.xml takes effect, maven will not access %MAVEN_HOME%\conf\setting.xml.

I Encounter similar issue while doing development on Android Studio 2.2.

My Machine Configuration -

1. JDK version 1.7.0_79 installed
2. JDK version 1.8.0_101 installed
3. Environment variable contains : JAVA_HOME = 1.7.0_79 JDK path and same is added to path variable
4. Project SDK Location = C:\Program Files\Java\jdk1.8.0_101

I then made below changes - 1. Uninstall JDK 1.7.0_79 2. Updated JAVA_HOME = 1.8.0_101 JDK path (Similar to SDK Location)

Now i am able to compile and run my application successfully , no more Unsupported major.minor version 52.0 Error

I faced the same error and realized that pom.xml had java 1.7 and STS compiler pointed to Java 1.8. Upon changing compiler to 1.7 and rebuild fixed the issue.

PS: This answer is not related to actual question posted but applies to similar error for app Context not loading

My solution:

1. remove all projects in current workspace
2. import all again
3. maven update project (Alt + F5) -> Select All and check Force Update of Snapshots/Releases
4. maven build (Ctrl + B) until there is nothing to build

It worked for me after the second try.

Here's how to fix this error when launching Eclipse:

Version 1.6.0_65 of the JVM is not suitable for this product. Version: 1.7 or greater is required.

1. Go and install latest JDK

2. Make sure you have installed 64 bit Eclipse

world !

No need to do execute batch command. With the current version, just run BLUESTACKS before ANDROID STUDIO

Without any plugins:

You just need to enable highlight: (Idea v.2016, 2017 and 2018, previous versions may have same or similar settings)

File -> Settings -> Editor -> Inspections -> Java -> Serialization issues -> Serializable class without 'serialVersionUID' - set flag and click 'OK'. (For Macs, Settings is under IntelliJ IDEA -> Preferences...)

Now, if your class implements Serializable, you will see highlight and alt+Enter on class name will ask you to generate private static final long serialVersionUID.

UPD: a faster way to find this setting - you might use hotkey Ctrl+Shift+A (find action), type Serializable class without 'serialVersionUID' - the first is the one.

The formula is

minSdkVersion <= targetSdkVersion <= compileSdkVersion

minSdkVersion - is a marker that defines a minimum Android version on which application will be able to install. Also it is used by Lint to prevent calling API that doesn’t exist. Also it has impact on Build Time. So you can use build flavors to override minSdkVersion to maximum during the development. It will help to make build faster using all improvements that the Android team provides for us. For example some features Java 8 are available only from specific version of minSdkVersion.

targetSdkVersion - If AndroidOS version is >= targetSdkVersion it says Android system to turn on specific(new) behavior changes. *Please note that some of new behaviors will be turned on by default even if thought targetSdkVersion is <, you should read official doc.

For example:

• Starting in Android 6.0 (API level 23) Runtime Permissions were introduced. If you set targetSdkVersion to 22 or lower your application does not ask a user for some permission in run time.

• Starting in Android 8.0 (API level 26), all notifications must be assigned to a channel or it will not appear. On devices running Android 7.1 (API level 25) and lower, users can manage notifications on a per-app basis only (effectively each app only has one channel on Android 7.1 and lower).

• Starting in Android 9 (API level 28), Web-based data directories separated by process. If targetSdkVersion is 28+ and you create several WebView in different processes you will get java.lang.RuntimeException

compileSdkVersion - actually it is SDK Platform version and tells Gradle which Android SDK use to compile. When you want to use new features or debug .java files from Android SDK you should take care of compileSdkVersion. One more example is using AndroidX that forces to use compileSdkVersion - level 28. compileSdkVersion is not included in your APK: it is purely used at compile time. Changing your compileSdkVersion does not change runtime behavior. It can generate for example new compiler warnings/errors. Therefore it is strongly recommended that you always compile with the latest SDK. You’ll get all the benefits of new compilation checks on existing code, avoid newly deprecated APIs, and be ready to use new APIs. One more fact is compileSdkVersion >= Support Library version

You can read more about it here. Also I would recommend you to take a look at the example of migration to Android 8.0.

[buildToolsVersion]

You need to add this in your build.gradle:

dependencies {
    ...
    compile 'com.android.support:cardview-v7:+'
}

And then Sync Project with Gradle Files. Finally, you can use CardView as it's described here.

There is no way to update an existing ADT bundle that you might have downloaded.

You can do one of two options:

1. Install Eclipse from eclipse.org and install ADT by pointing to the update site: https://dl-ssl.google.com/android/eclipse

2. Download bundles from:

   • Linux 64 bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip

   • Linux 32 bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip

   • Mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip

   • Windows 32 bit: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip

   • Windows 64 bit: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip

Starting with ADT bundle 23.0.2, you should be able to update to future versions of ADT.

Java 8 supports default methods in interfaces. And in JDK 8 a lot of old interfaces now have new default methods. For example, now in CharSequence we have chars and codePoints methods.
If source level of your project is lower than 1.8, then compiler doesn't allow you to use default methods in interfaces. So it cannot compile classes that directly on indirectly depend on this interfaces.
If I get your problem right, then you have two solutions. First solution is to rollback to JDK 7, then you will use old CharSequence interface without default methods. Second solution is to set source level of your project to 1.8, then your compiler will not complain about default methods in interfaces.

One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.

@SpringBootApplication
public class ChildApplication extends ParentApplication{
    public static void main(String[] args) {
        SpringApplication.run(ChildApplication.class, args);
    }
}

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
  </dependency>

1. In Eclipse, click on Windows > Preferences, and then choose Maven in the left side.
2. Check the box "Download repository index updates on startup".
   • Optionally, check the boxes Download Artifact Sources and Download Artifact JavaDoc.
3. Click OK. The warning won't appear anymore.
4. Restart Eclipse.

On terminal type mvn -v and the output will look like the image shown below

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

place your main method class in src folder(in Eclipse Environment).

I didn't need to set up remote debugging in order to get this working, I used Maven.

1. Ensure you have the Maven plugin installed into Eclipse.
2. Click Run > Run Configurations > Maven Build > new launch configuration:
   • Base directory: browse to the root of your project
   • Goals: spring-boot::run.
3. Click Apply then click Run.

NB. If your IDE has problems finding your project's source code when doing line-by-line debugging, take a look at this SO answer to find out how to manually attach your source code to the debug application.

Hope this helps someone!

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

I'd the same problem and excluding the DataSourceAutoConfiguration solved the problem.

@SpringBootApplication
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class RecommendationEngineWithCassandraApplication {

    public static void main(String[] args) {
        SpringApplication.run(RecommendationEngineWithCassandraApplication.class, args);
    }
}

One way is to use re.sub, that's my preferred way.

import re
my_str = "hey th~!ere"
my_new_string = re.sub('[^a-zA-Z0-9 \n\.]', '', my_str)
print my_new_string

Output:

hey there

Another way is to use re.escape:

import string
import re

my_str = "hey th~!ere"

chars = re.escape(string.punctuation)
print re.sub(r'['+chars+']', '',my_str)

Output:

hey there

Just a small tip about parameters style in python by PEP-8 parameters should be remove_special_chars and not removeSpecialChars

Also if you want to keep the spaces just change [^a-zA-Z0-9 \n\.] to [^a-zA-Z0-9\n\.]

The Android implementation of mipmaps in 4.3 is exactly the technique from 1983 explained in the Wikipedia article :)

Each bitmap image of the mipmap set is a downsized duplicate of the main texture, but at a certain reduced level of detail. Although the main texture would still be used when the view is sufficient to render it in full detail, the renderer will switch to a suitable mipmap image (...) when the texture is viewed from a distance or at a small size.

Although this is described as a technique for 3D graphics (as it mentions "viewing from a distance"), it applies just as well to 2D (translated as "drawn is a smaller space", i.e. "downscaled").

For a concrete Android example, imagine you have a View with a certain background drawable (in particular, a BitmapDrawable). You now use an animation to scale it to 0.15 of its original size. Normally, this would require downscaling the background bitmap for each frame. This "extreme" downscaling, however, may produce visual artifacts.

You can, however, provide a mipmap, which means that the image is already pre-rendered for a few specific scales (let's say 1.0, 0.5, and 0.25). Whenever the animation "crosses" the 0.5 threshold, instead of continuing to downscale the original, 1.0-sized image, it will switch to the 0.5 image and downscale it, which should provide a better result. And so forth as the animation continues.

This is a bit theoretical, since it's actually done by the renderer. According to the source of the Bitmap class, it's just a hint, and the renderer may or may not honor it.

/**
 * Set a hint for the renderer responsible for drawing this bitmap
 * indicating that it should attempt to use mipmaps when this bitmap
 * is drawn scaled down.
 *
 * If you know that you are going to draw this bitmap at less than
 * 50% of its original size, you may be able to obtain a higher
 * quality by turning this property on.
 * 
 * Note that if the renderer respects this hint it might have to
 * allocate extra memory to hold the mipmap levels for this bitmap.
 *
 * This property is only a suggestion that can be ignored by the
 * renderer. It is not guaranteed to have any effect.
 *
 * @param hasMipMap indicates whether the renderer should attempt
 *                  to use mipmaps
 *
 * @see #hasMipMap()
 */
public final void setHasMipMap(boolean hasMipMap) {
    nativeSetHasMipMap(mNativeBitmap, hasMipMap);
}

I'm not quite sure why this would be especially suitable for application icons, though. Although Android on tablets, as well as some launchers (e.g. GEL), request an icon "one density higher" to show it bigger, this is supposed to be done using the regular mechanism (i.e. drawable-xxxhdpi, &c).

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

I had the same problem because there was files with windows-1251 encoding and Cyrillic comments. In Android Studio which is based on IntelliJ IDEA you can solve it in two ways:

a) convert file encoding to UTF-8 or

b) set the right file encoding in your build.gradle script:

android {
    ...
    compileOptions.encoding = 'windows-1251' // write your encoding here
    ...

To convert file encoding use the menu at the bottom right corner of IDE. Select right file encoding first -> press Reload -> select UTF-8 -> press Convert.

Also read this Use the UTF-8, Luke! File Encodings in IntelliJ IDEA

If you are doing code in STS you just need to add the devtools dependency in your maven file. After that it will run itself whenever you will do some change.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
</dependency>

You should make your audioSounds and minTime members static:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

But I would consider using singleton objects instead of static members instead:

public class SoundManager : MonoBehaviour
{

    public List<AudioSource> audioSounds = new List<AudioSource>();
    public double minTime = 0.5;

    public static SoundManager Instance { get; private set; }

    void Awake()
    {
        Instance = this;
    }

    public void playSound(AudioClip sourceSound, Vector3 objectPosition, int volume, float audioPitch, int dopplerLevel)
    {    
        bool playsound = false;
        foreach (AudioSource sound in audioSounds) // Loop through List with foreach
        {  
            if (sourceSound.name != sound.name && sound.time <= minTime)
            {
                playsound = true;
            }
        }

        if(playsound) {
            AudioSource.PlayClipAtPoint(sourceSound, objectPosition);
        }

    }
}

Update from September 2020:

Six years later, it is still one of my most upvoted answers on StackOverflow, so I feel obligated to add: singleton is a pattern that creates a lot of problems down the road, and personally, I consider it to be an anti-pattern. It can be accessed from anywhere, and using singletons for different game systems creates a spaghetti of invisible dependencies between different parts of your project.

If you're just learning to program, using singletons is OK for now. But please, consider reading about Dependency Injection, Inversion of Control and other architectural patterns. At least file it under "stuff I will learn later". This may sound as an overkill when you first learn about them, but a proper architecture can become a life-saver on middle and big projects.

Remove all the texts in android/settings.gradle and paste the below code

rootProject.name = '****Your Project Name****'
apply from: file("../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'

This issue will usually happen when you migrate from react-native < 0.60 to react-native >0.60. If you create a new project in react-native >0.60 you will see the same settings as above mentioned

The Device File Explorer that is part of Android Studio 3.x is really good for exploring your preference file(s), cache items or database.

1. Shared Preferences /data/data//shared_prefs directory

It looks something like this

To open The Device File Explorer:

Click View > Tool Windows > Device File Explorer or click the Device File Explorer button in the tool window bar.

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

Cheers

On my end, I used Resource Monitor to see which application was still listening to port 5037 after all the Eclipse and adb restart were unsuccessful for me.

Start > All Programs > Accessories > System Tools >
Resource Monitor > Network > Listening Ports

This eventually showed that java.exe was listening to port 5037, hence, preventing adb from doing so. I killed java.exe, immediately start adb (with adb start-server) and received a confirmation that adb was able to start:

android-sdks\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

wrapper div{
   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }
   quote wrapper div{
       div for individual quote{
          quote
       }
   }

Reinstall java and choose a destination folder without a space

This worked for me: Open task manager (of your OS) and kill adb.exe process. Now start adb again, now adb should start normally.

Disconnect your device from the computer.

Go into developer settings.

Turn off developer settings.

Turn on developer settings.

Enable USB Debugging (and whatever other settings you enabled beforehand)

Reconnect your device to the computer.

Try again.

Worked for me so hope it works for you!

from command prompt:

set ANDROID_SDK_HOME=C:\[wherever your sdk folder is]

should do the trick.

use this code it is working

I faced the same error, but only with files cloned from git that were assigned to a proprietary plugin. I realized that even after cloning the files from git, I needed to create a new project or import a project in eclipse and this resolved the error.

I had this info message "No Spring WebApplicationInitializer types detected on classpath" while deploying a WAR with spring integration beans in WebLogic server. Actually, I could observe that the servlet URL returned 404 Not Found and beside that info message with a negative tone "No Spring ...etc" in Server logs, nothing else was seemingly in error in my spring config; no build or deployment errors, no complaints. Indeed, I suspected that the beans.xml (spring context XML) was actually not picked up at all and that was bound to the very specific organizing of artefacts in Oracle's jDeveloper. The solution is to play carefully with the 'contributors' and 'filters' for the WEB-INF/classes category when you edit your deployment profile under the 'deployment' topic in project properties.

Precisely, I would advise to name your spring context by the jDeveloper default "beans.xml" and place it side by side to the WEB-INF subdirectory itself (under your web Apllication source path, e.g. like <...your project path>/public_html/). Then in the WEB-INF/classes category (when editing the deployment profile) your can check the Project HTML root directory in the 'contributor' list, and then select the beans.xml in filters, and then ensure your web.xml features a context-param value like classpath:beans.xml.

Once that was fixed, I was able to progress and after some more bean config changes and implementations, the message "No Spring WebApplicationInitializer types detected on classpath" came back! Actually, I did not notice when and why exactly it came back. This second time, I added a

public class HttpGatewayInit implements WebApplicationInitializer { ... }

which implements empty inherited methods, and the whole application works fine!

...If you feel that java EE development has been getting a bit too crazy with cascades of XML configuration files (some edited manually, others through wizards) intepreted by cascades of variant initializers, let me insist that I fully share your point.

The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with

conda install -c anaconda pandas 

Unfortunately I do not know how to help with Eclipse.

How to diagnose this error even when running the simple command:

java -version
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Cannot create GC thread. Out of system resources.
# An error report file with more information is saved as:
# /home2/ericlesc/code/java/c2/hs_err_pid23944.log

Check the amount of free memory you have:

free -m
             total       used       free     shared    buffers     cached
Mem:         28119      26643       1475        189       2391      15368
-/+ buffers/cache:       8884      19235
Swap:         5117         34       5083

Check the max number of user processes, make sure you are not over limit:

ulimit -a

ps -ef | wc -l

For me, the reason this happened was because PHP had consumed too much memory allocated to me on bluehost, and the way I was able to fix it, without restarting PHP or the server ( I can't ) was to take the public_html directory and rename it. And give it a minute for PHP to see the change, then rename it back.

A bug in the php engine itself. I found a clever way to give the PHP engine a swift kick.

(update Feb 2016) (I'm getting a spike of up-votes on this because Bluehost instance PHP engines are reserving all the memory and leaving none for the JVM. In their defense, PHP is evolving into an unholy rube Goldberg machine. Bluehost as a service is on the decline.

Stop installing android studio 3.0.1 and go back 2.3.3 ( Stable version) . Check for the stable version and you can find them a lot

All you have to do uninstall and go back to the other version. Yes it asks to create gradle file seperately which is completely new to me!

Failure is the stepping stone for success..

To compile with Java 8 (lambdas etc) in IntelliJ IDEA 15;

• CTRL + ALT + SHIFT + S or File / Project Structure

• Open Project tab

• Set Project SDK to compatible java version (1.8)

• Set Project language level to 8

• Open Modules tab

• Set Language level to 8, click OK

• CTRL + ALT + S or File / Settings

• Build, Execution, Deployment / Compiler / Java Compiler

• Change Target bytecode version to 1.8, click OK

IntelliJ has no option to click on a file and choose "Add to .gitignore" like Eclipse has.

The quickest way to add a file or folder to .gitignore without typos is:

1. Right-click on the file in the project browser and choose "Copy Path" (or use the keyboard shortcut that is displayed there).
2. Open the .gitignore file in your project, and paste.
3. Adjust the pasted line so that it is relative to the location of the .gitignore file.

Additional info: There is a .ignore plugin available for IntelliJ which adds a "Add to .gitignore" item to the popup menu when you right-click a file. It works like a charm.

you can just using this lib for easy realize the copy goal!

https://clipboardjs.com/

Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.

That's why clipboard.js exists.

or

https://github.com/zeroclipboard/zeroclipboard

http://zeroclipboard.org/

The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface.

Just to add a bit of extra info over the right solution. Be aware that you'll need this class org.apache.catalina.filters.CorsFilter. So in order to have it, if your tomcat is not 7.0.41 or higher, download 'tomcat-catalina.7.0.41.jar' or higher ( you can do it from http://mvnrepository.com/artifact/org.apache.tomcat/tomcat-catalina ) and put it in the 'lib' folder inside Tomcat installation folders. I actually used 7.0.42 Hope it helps!

Mine were located here on Ubuntu 18.04 when I installed JavaFX using apt install openjfx (as noted already by @jewelsea above)

In Eclipse Kepler it is very easy to generate Web Service Client classes,You can achieve this by following steps .

RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish

You will see the generated classes are inside your src folder.

NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

Generally, I think your USB connection should be set to use MTP (Media Transfer), however, I couldn't get my computer to recognize my device (Nexus 4). Oddly, setting the USB connection to Camera got it working for me.

Hi I faced similar problem with a project, in IntelliJ with Maven dependencies.

I solved it changing the dependencies scope from provided to compile.

IntelliJ:

File > project structure > Modules > Dependencies > scope (provide to compile)

It's very annoying. I'm not sure why Google places it there - no one needs these trash from emulator at all; we know what we are doing. I'm using pidcat and I modified it a bit
BUG_LINE = re.compile(r'.*nativeGetEnabledTags.*') BUG_LINE2 = re.compile(r'.*glUtilsParamSize.*') BUG_LINE3 = re.compile(r'.*glSizeof.*')

and
bug_line = BUG_LINE.match(line) if bug_line is not None: continue bug_line2 = BUG_LINE2.match(line) if bug_line2 is not None: continue bug_line3 = BUG_LINE3.match(line) if bug_line3 is not None: continue

It's an ugly fix and if you're using the real device you may need those OpenGL errors, but you got the idea.

Step 1: Create a maven project in Eclipse and add the below dependency in the pom.xml

<dependencies>
  <dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.18</version>
</dependency>

Step 2: Run As --> Configuraitons --> Goto Arguments --> give arguments like below maven -clean install

Step 3: Run As --> maven clean

Once you do the maven clean you see Build Success and lombok jar file in the maven Dependencies

Step 4: Goto the jar location as shown in the below screen shot.

Step 5: Give command as shown like below after reaching in the .m2 folder

Step 6: Locate where is your eclipse folder once you this window.Once you see Install Successfull message click on Quit Installer option at the bottom.

Step 7 : We have finished installing the lombok.jar successfully .Now restart your Eclipse IDE and Start below Sample Code to check whether the data is coming or not in the getters and setters.

Step 8: Open Eclipse and create simple Java Maven project and see in the Outline section you can see getters and setters are created you can use either @Data or @Getter @Setter On top of class or you can give on top of variable

@Getter @Setter
privateString riverName;

{OR}

@Getter
@Setter
Class River{
String riverName;
}

[OR]

@Data
class River 
{
Private String riverName;

}

You can see the project structure and Outline Structure how it got created in simple steps.

According to http://developer.android.com/guide/topics/ui/actionbar.html

The ActionBar APIs were first added in Android 3.0 (API level 11) but they are also available in the Support Library for compatibility with Android 2.1 (API level 7) and above.

In short, that auto-generated project you're seeing modularizes the process of adding the ActionBar to APIs 7-10.

See http://hmkcode.com/add-actionbar-to-android-2-3-x/ for a simplified explanation and tutorial on the topic.

Easy solution without need for pathes:

open -b com.jetbrains.pycharm

You can set it as alias for every-day easier usage (put to your .bash_rc etc.):

alias pycharm='open -b com.jetbrains.pycharm'

Usage:

pycharm .
pycharm file.py

The problem:

java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

indicates that you try to use the Jersey 2.x servlet, but you are supplying the Jersey 1.x libs.

For Jersey 1.x you have to do it like this:

<servlet>
  <servlet-name>Jersey REST Service</servlet-name>
<servlet-class>
  com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>sample.hello.resources</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>Jersey REST Service</servlet-name>
  <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

For more information check the Jersey 1.x documentation.

If you instead want to use Jersey 2.x then you'll have to supply the Jersey 2.x libs. In a maven based project you can use the following:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.xx</version>
</dependency>
<!-- if you are using Jersey client specific features without the server side -->
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.xx</version>
</dependency>

For Jersey 2.x you don't need to setup anything in your web.xml, it is sufficient to supply a class similar to this:

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("rest")
public class ApplicationConfig extends Application {

}

For more information, check the Jersey documentation.

Could it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.

The tutorial Debugging with Android Studio also helps, specially this paragraph :

To track memory allocation of objects:

1. Start your app as described in Run Your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. On the Android DDMS tool window, select the Devices | logcat tab.
4. Select your device from the dropdown list.
5. Select your app by its package name from the list of running apps.
6. Click Start Allocation Tracking Interact with your app on the device. Click Stop Allocation Tracking

Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:

In my case the error was: CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 ....

With eclipse luna from console in the pom.xml folder

mvn clean
mvn install

With Juno I had to had this to my pom.xml

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>2.3.2</version>
          <configuration>
            <!-- put your configurations here -->
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

And then

mvn install

And then from eclipse right click>maven>update project * Once the plugin is donwloaded you can remove the plugin from your pom.xml

Click on Tools > SDK Manager or click SDK Manager after If you are unable to see the location of your Android SDK Location, click on edit and create a folder where you want to keep it and then click Next and Finish

if you experience this exception while using intellij and you are trying to start the application with the run button. Try starting the application from the command line instead. E.g. ensure that you are in the correct directory (directory with your pom file) assuming this is a springboot application run mvn spring-boot:run this did the trick for me.

Additionally I have also seen this error occur when your spring application depends on another application. In this case I had to start the other application first then run.

As others have noted, in order for a jar file to be executable, the application's entry point must be set in the Main-Class attribute of the manifest file. If the dependency class files are not collocated, then they need to be set in the Class-Path entry of the manifest file.

I have tried all kinds of plugin combinations and what not for the simple task of creating an executable jar and somehow someway, include the dependencies. All plugins seem to be lacking one way or another, but finally I got it like I wanted. No mysterious scripts, not a million different mini files polluting the build directory, a pretty clean build script file, and above all: not a million foreign third party class files merged into my jar archive.

The following is a copy-paste from here for your convenience..

[How-to] create a distribution zip file with dependency jars in subdirectory /lib and add all dependencies to Class-Path entry in the manifest file:

apply plugin: 'java'
apply plugin: 'java-library-distribution'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.apache.commons:commons-lang3:3.3.2'
}

// Task "distZip" added by plugin "java-library-distribution":
distZip.shouldRunAfter(build)

jar {
    // Keep jar clean:
    exclude 'META-INF/*.SF', 'META-INF/*.DSA', 'META-INF/*.RSA', 'META-INF/*.MF'

    manifest {
        attributes 'Main-Class': 'com.somepackage.MainClass',
                   'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' ')
    }
    // How-to add class path:
    //     https://stackoverflow.com/questions/22659463/add-classpath-in-manifest-using-gradle
    //     https://gist.github.com/simon04/6865179
}

Hosted as a gist here.

The result can be found in build/distributions and the unzipped contents look like this:

lib/commons-lang3-3.3.2.jar
MyJarFile.jar

Contents of MyJarFile.jar#META-INF/MANIFEST.mf:

Manifest-Version: 1.0
Main-Class: com.somepackage.MainClass
Class-Path: lib/commons-lang3-3.3.2.jar

I had the same problem, Android Studio just could not identify the android-sdk folder. All I did was to uninstall and reinstall android studio, and this time it actually identified the folder. Hope it also works out for you.

You only need to delete one folder it is throwing error for. Just go to your M2 repo and org/apache/maven/plugins/maven-compiler-plugins and delete the folder 2.3.2

I also find it confusing to resolve merge conflicts in EGit. When I am ready to commit some changes to a shared repository, the steps I have learned are as follows:

1. Right click on the project and choose Team: Commit....
2. Review my changes to check that I'm not committing any changes I made accidentally or unrelated changes that I forgot about. Write up the commit message while I'm reviewing the changes.
3. I'm optimistic, so I start by clicking the Commit and Push button. If no one else has pushed any changes, I'm done. If someone has, then the commit succeeds, and the push gets rejected.
4. Right click on the project and choose Team: Pull. If there are no conflicts, then choose Team: Push to Upstream and I'm done.
5. If there are conflicts, look through the package explorer to see which files are conflicted. Right click on each conflicted file, and choose Team: Merge Tool. It will show all the changes in both versions of the file, with any conflicts shown in red. Click on the button to merge all non-conflict changes, then edit any red sections manually. There's also a button to show a three way merge that includes the common ancestor.
6. Save the changes to the file. If you want, you can compare it to HEAD to see what changes you are making on top of the changes you just pulled.
7. Right click on the file and choose Team: Add to Index to tell EGit that you've finished merging that file. To me, this is the least intuitive step, but the git command line also uses the add command to show that a merge is finished.
8. Repeat for any other conflicted files.
9. When all the files are merged, right click on the project and choose Team: Rebase: Continue Rebase. If there are more conflicted commits, go back to dealing with conflicts.
10. When the rebase is complete, run your tests to see that the rebase didn't break anything.
11. Right click on the project and choose Team: Push to Upstream.

You should be using Maven, as the structure is standardized. To do that (Once you have created your Maven project in Netbeans, just

1. Go to File -> Import
2. Open Maven tree node
3. Select Existing Maven Project
4. Browse to find your project from NetBeans
5. Check Add project to Working Set
6. Click finish.

As long as the project has no errors, I usually get none transferring to eclipse. This works for Maven web projects and regular projects.

I had a similar issue and was able to resolve it by identifying which JDBC driver I intended to use. In my case, I was connecting to an Oracle database. I placed the following statement, prior to creating the connection variable.

DriverManager.registerDriver( new oracle.jdbc.driver.OracleDriver());

There is no direct equivalent to mvn exec:java in gradle, you need to either apply the application plugin or have a JavaExec task.

application plugin

Activate the plugin:

plugins {
    id 'application'
    ...
}

Configure it as follows:

application {
    mainClassName = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
}

On the command line, write

$ gradle -PmainClass=Boo run

JavaExec task

Define a task, let's say execute:

task execute(type:JavaExec) {
   main = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
   classpath = sourceSets.main.runtimeClasspath
}

To run, write gradle -PmainClass=Boo execute. You get

$ gradle -PmainClass=Boo execute
:compileJava
:compileGroovy UP-TO-DATE
:processResources UP-TO-DATE
:classes
:execute
I am BOO!

mainClass is a property passed in dynamically at command line. classpath is set to pickup the latest classes.

If you do not pass in the mainClass property, both of the approaches fail as expected.

$ gradle execute

FAILURE: Build failed with an exception.

* Where:
Build file 'xxxx/build.gradle' line: 4

* What went wrong:
A problem occurred evaluating root project 'Foo'.
> Could not find property 'mainClass' on task ':execute'.

I have written detailed example on circular progress bar in android here on my blog demonuts.com. You can also fond full source code and explanation there.

                    android:pivotY="50%"
                    android:toDegrees="360" />

                <gradient
                    android:centerColor="#00FF00"
                    android:endColor="#00FF00"
                    android:startColor="#00FF00"
                    android:type="sweep" />

            </shape>
        </rotate>
    </item>
</layer-list>

Now in your activity_main.xml add following:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/dialog"
    tools:context="com.example.parsaniahardik.progressanimation.MainActivity">

    <ProgressBar

        android:id="@+id/circularProgressbar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:indeterminate="false"
        android:max="100"
        android:progress="50"
        android:layout_centerInParent="true"
        android:progressDrawable="@drawable/circular"
        android:secondaryProgress="100"
        />

    <ImageView
        android:layout_width="90dp"
        android:layout_height="90dp"
        android:background="@drawable/whitecircle"
        android:layout_centerInParent="true"/>

    <TextView
        android:id="@+id/tv"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:gravity="center"
        android:text="25%"
        android:layout_centerInParent="true"
        android:textColor="@color/colorPrimaryDark"
        android:textSize="20sp" />

</RelativeLayout>

In activity_main.xml I have used one circular image with white background to show white background around percentage. Here is the image:

You can change color of this image to set custom color around percentage text.

Now finally add following code to MainActivity.java :

import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.animation.DecelerateInterpolator;
import android.widget.ProgressBar;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    int pStatus = 0;
    private Handler handler = new Handler();
    TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Resources res = getResources();
        Drawable drawable = res.getDrawable(R.drawable.circular);
        final ProgressBar mProgress = (ProgressBar) findViewById(R.id.circularProgressbar);
        mProgress.setProgress(0);   // Main Progress
        mProgress.setSecondaryProgress(100); // Secondary Progress
        mProgress.setMax(100); // Maximum Progress
        mProgress.setProgressDrawable(drawable);

      /*  ObjectAnimator animation = ObjectAnimator.ofInt(mProgress, "progress", 0, 100);
        animation.setDuration(50000);
        animation.setInterpolator(new DecelerateInterpolator());
        animation.start();*/

        tv = (TextView) findViewById(R.id.tv);
        new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                while (pStatus < 100) {
                    pStatus += 1;

                    handler.post(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            mProgress.setProgress(pStatus);
                            tv.setText(pStatus + "%");

                        }
                    });
                    try {
                        // Sleep for 200 milliseconds.
                        // Just to display the progress slowly
                        Thread.sleep(8); //thread will take approx 1.5 seconds to finish
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }).start();
    }
}

If you want to make horizontal progressbar, follow this link, it has many valuable examples with source code:
http://www.skholingua.com/android-basic/user-interface/form-widgets/progressbar

Follow the steps mentioned for using support ActionBar in Android Studio(0.4.2) :

Download the Android Support Repository from Android SDK Manager, SDK Manager icon will be available on Android Studio tool bar (or Tools -> Android -> SDK Manager).

After download you will find your Support repository here

$SDK_DIR\extras\android\m2repository\com\android\support\appcompat-v7

Open your main module's build.gradle file and add following dependency for using action bar in lower API level

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

Sync your project with gradle using the tiny Gradle icon available in toolbar (or Tools -> Android -> Sync Project With Gradle Files).

There is some issue going on with Android Studio 0.4.2 so check this as well if you face any issue while importing classes in code.

Import Google Play Services library in Android Studio

If Required follow the steps as well :

• Exit Android Studio
• Delete all the .iml files and files inside .idea folder from your project
• Relaunch Android Studio and wait till the project synced completely with gradle. If it shows an error in Event Log with import option click on Import Project.

This is bug in Android Studio 0.4.2 and fixed for Android Studio 0.4.3 release.

I'm a little late to the party but I'll give my two cents. I just resolved this issue after spending longer than I'd like on it. The above solutions didn't work for me and here's why:

there was a network issue when maven was downloading the required repositories so I actually didn't have the right jars. adding a -U to a maven clean install went and got them for me. So if the above solutions aren't working try this:

1. Right click on your project -> Choose Run as -> 5 Maven build...
2. In the Goals field type "clean install -U" and select Run
3. After that completes right click on your project again and choose Maven -> Update Project and click ok.

Hope it works for you.

Change your main to:

public static void main(String[] args) {
    EchoServer echoServer = new EchoServer();
    echoServer.listen();
}

When you declare Object EchoServer0; you have a few mistakes.

1. EchoServer0 is of type Object, therefore it doesn't have the method listen().
2. You will also need to create an instance of it with new.
3. Another problem, this is only regarding naming conventions, you should call your variables starting by lower case letters, echoServer0 instead of EchoServer0. Uppercase names are usually for class names.
4. You should not create a variable with the same name as its class. It is confusing.

If you just want to re-load/update dependencies (I assume, with constantly changing you mean either SNAPSHOTS or local dependencies you update yourself), you can use

mvn dependency:resolve

For that I wrote a bash script:

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | awk '{if ($1 == "modified:") print $2;}'`
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool  FETCH_HEAD $file ;
done

In the above script, I fetch the remote main branch (not necessary its master branch ANY branch) to FETCH_HEAD, then make a list of my modified file only and compare modified files to git difftool.

There are many difftool supported by git, I configured Meld Diff Viewer for good GUI comparison.
From the above script, I have prior knowledge what changes done by other teams in same file, before I follow git stages untrack-->staged-->commit which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on the main branch.

For me (on windows 10), I was getting the error "No compiler is provided in this environment" at the Windows command prompt when I ran mvn install. The fix was changing the JAVA_HOME environment variable to point to my jdk (C:\Program Files\Java\jdk1.8.0_101); previously it had pointed to the jre.

And to get Eclipse to use the new jdk, I edited eclipse.ini in my eclipse distribution and changed the line for -vm to C:\Program Files\Java\jdk1.8.0_101\bin.

Android Studio 2.2 came out with the ability to use ndk-build and cMake. Though, we had to wait til 2.2.3 for the Application.mk support. I've tried it, it works...though, my variables aren't showing up in the debugger. I can still query them via command line though.

You need to do something like this:

externalNativeBuild{
   ndkBuild{
        path "Android.mk"
    }
}

defaultConfig {
  externalNativeBuild{
    ndkBuild {
      arguments "NDK_APPLICATION_MK:=Application.mk"
      cFlags "-DTEST_C_FLAG1"  "-DTEST_C_FLAG2"
      cppFlags "-DTEST_CPP_FLAG2"  "-DTEST_CPP_FLAG2"
      abiFilters "armeabi-v7a", "armeabi"
    }
  } 
}

See http://tools.android.com/tech-docs/external-c-builds

NB: The extra nesting of externalNativeBuild inside defaultConfig was a breaking change introduced with Android Studio 2.2 Preview 5 (July 8, 2016). See the release notes at the above link.

right click somewhere on the file or in project explorer and choose 'run as'->'java application'

Below are the steps you can try it out to resolve the issue: -

1. Provide reference of AppCompat Library into your project.
2. If option 1 doesn't solve the issue then you can try to change the style.xml file to below code.

 parent="android:Theme.Holo.Light"  

instead.

 parent="android:Theme.AppCompat.Light"  

But option 2 will require minimum sdk version 14.

Hope this will help !

Can you be a bit more specific about what you're trying to do and how you're trying to do it?

If you're attempting to invoke the program using the <exec> task you might do the following:

<exec executable="name-of-executable">
  <arg value="arg0"/>
  <arg value="arg1"/>
</exec>

You can write a query as follows:

IF OBJECT_ID('ProcedureName','P') IS NOT NULL
    DROP PROC ProcedureName
GO

CREATE PROCEDURE [dbo].[ProcedureName]
...your query here....

To be more specific on the above syntax:
OBJECT_ID is a unique id number for an object within the database, this is used internally by SQL Server. Since we are passing ProcedureName followed by you object type P which tells the SQL Server that you should find the object called ProcedureName which is of type procedure i.e., P

This query will find the procedure and if it is available it will drop it and create new one.

For detailed information about OBJECT_ID and Object types please visit : SYS.Objects

There are two ways to use void:

void foo(void);

or

void *bar(void*);

The first indicates that no argument is being passed or that no argument is being returned.

The second tells the compiler that there is no type associated with the data effectively meaning that the you can't make use of the data pointed to until it is cast to a known type.

For example you will see void* used a lot when you have an interface which calls a function whose parameters can't be known ahead of time.

For example, in the Linux Kernel when deferring work you will setup a function to be run at a latter time by giving it a pointer to the function to be run and a pointer to the data to be passed to the function:

struct _deferred_work {
sruct list_head mylist;
.worker_func = bar;
.data        = somedata;
} deferred_work;

Then a kernel thread goes over a list of deferred work and when it get's to this node it effectively executes:

bar(somedata);

Then in bar you have:

void bar(void* mydata) {
    int *data = mydata;
    /* do something with data */;
}

If you need to store permanent path (path is not changed when cmd is restart)

1. Run the Command Prompt as administrator (Right click on cmd.exe and select run as administrator)

2. In cmd setx path "%path%;your new path" then enter

3. Check whether the path is taken correctly by typing path and pressing enter

Robot robot = new Robot();
robot.mouseMove(coordinates.x,coordinates.y+80);

Rotbot is good solution. It works for me.

For attached properties you can either call SetValue on the object for which you want to assign the value:

tblock.SetValue(Grid.RowProperty, 4);

Or call the static Set method (not as an instance method like you tried) for the property on the owner type, in this case SetRow:

Grid.SetRow(tblock, 4);

Effects are always executed after the render phase is completed even if you setState inside the one effect, another effect will read the updated state and take action on it only after the render phase.

Having said that its probably better to take both actions in the same effect unless there is a possibility that b can change due to reasons other than changing a in which case too you would want to execute the same logic

You need to stop the event from reaching (bubbling to) the parent (the div). See the part about bubbling here, and jQuery-specific API info here.

Add programatically noborder class to specific row to hide it

1. https://pypi.python.org/pypi/openpyxl download zip file and unzip it on local system.
2. go to openpyxl folder where setup.py is present.
3. open command prompt under the same path.
4. Run a command: python setup.py install
5. It will install openpyxl.

When you use a code like this:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   // Do something with the key...
   // Encrypt, export, etc.
}

.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET

This means:

1. Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.

2. Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).

To resolve these issues:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   try
   {
      // Do something with the key...
      // Encrypt, export, etc.
   }
   finally
   {
      rsa.PersistKeyInCsp = false;
   }
}

Try this:

import requests
import json

# Goole Maps API.
link = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'

# Request data from link as 'str'
data = requests.get(link).text

# convert 'str' to Json
data = json.loads(data)

# Now you can access Json 
for i in data['routes'][0]['legs'][0]['steps']:
    lattitude = i['start_location']['lat']
    longitude = i['start_location']['lng']
    print('{}, {}'.format(lattitude, longitude))

The mysql_* functions are deprecated and unsafe. The code in your question in vulnerable to injection attacks. It is highly recommended that you use the PDO extension instead, like so:

session_start();

$query = "SELECT 'id' FROM Users WHERE username = :name LIMIT 1";
$statement = $PDO->prepare($query);
$params = array(
    'name' => $_GET["username"]
);
$statement->execute($params);
$user_data = $statement->fetch();

$_SESSION['myid'] = $user_data['id'];

Where $PDO is your PDO object variable. See https://www.php.net/pdo_mysql for more information about PHP and PDO.

For extra help:

Here's a jumpstart on how to connect to your database using PDO:

$database_username = "YOUR_USERNAME";
$database_password = "YOUR_PASSWORD";
$database_info = "mysql:host=localhost;dbname=YOUR_DATABASE_NAME";
try
{
    $PDO = new PDO($database_info, $database_username, $database_password);
}
catch(PDOException $e)
{
    // Handle error here
}

If you have all the features of type object then the first answer written above works well https://stackoverflow.com/a/31939145/5840973.

But, Suppose when we have mixed type columns. Then we can fetch the list of features names of type object type programmatically and then Label Encode them.

#Fetch features of type Object
objFeatures = dataframe.select_dtypes(include="object").columns

#Iterate a loop for features of type object
from sklearn import preprocessing
le = preprocessing.LabelEncoder()

for feat in objFeatures:
    dataframe[feat] = le.fit_transform(dataframe[feat].astype(str))
 

dataframe.info()

This will never work, because the JS VM has moved on from that async_call and returned the value, which you haven't set yet.

Don't try to fight what is natural and built-in the language behaviour. You should use a callback technique or a promise.

function f(input, callback) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) { callback(result) };

}

The other option is to use a promise, have a look at Q. This way you return a promise, and then you attach a then listener to it, which is basically the same as a callback. When the promise resolves, the then will trigger.

Cleaner way, exploit shortcut evaluation of shell logical operators. Right side of the operator is executed only if left side is true.

[ ! -d /home/mlzboy/b2c2/shared/db ] && mkdir -p /home/mlzboy/b2c2/shared/db

You can store them as static variables of a class:

class Constants {
    public static $array = array('guy', 'development team');
}
# Warning: array can be changed lateron, so this is not a real constant value:
Constants::$array[] = 'newValue';

If you don't like the idea that the array can be changed by others, a getter might help:

class Constants {
    private static $array = array('guy', 'development team');
    public static function getArray() {
        return self::$array;
    }
}
$constantArray = Constants::getArray();

EDIT

Since PHP5.4, it is even possible to access array values without the need for intermediate variables, i.e. the following works:

$x = Constants::getArray()['index'];

This highlighting effect is due to the action called hover (onMouseHover).

When you will hover on any tab its color will be changed.

Just say for example,

HTML code

<div class="menu">
    <ul class="effect">
        <li>Questions</li>
        <li>JOBS</li>
        <li>Users</li>
    </ul>
</div>

CSS code

.effect:hover {
    color: none;
}

You can use any color if you want to get it highlighted. Else you can use none.

Personally I like to validate the form on submit and if there are errors, just return false.

$('form').submit(function() {

    var error;

   if ( !$('input').val() ) {
        error = true
    }

    if (error) {
         alert('there are errors')
         return false
    }

});

No its not possible but you can make use of div and put table in div

<div style="height: 100px; overflow: auto">
  <table style="height: 500px;">
   ...
  </table>
</div>

The postition:absolute; tag positions the element relative to it's immediate parent. I noticed that even in the examples, there isn't room for scrolling, and when i tried it out, it didn't work. Therefore, to pull off the facebook floating menu, the position:fixed; tag should be used instead. It displaces/keeps the element at the given/specified location, and the rest of the page can scroll smoothly - even with the responsive ones.

Please see CSS postion attribute documentation when you can :)

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

this solution is robust even in executables

import inspect, os.path

filename = inspect.getframeinfo(inspect.currentframe()).filename
path     = os.path.dirname(os.path.abspath(filename))

I think the most simple way is .iloc[[0, -1]].

df = pd.DataFrame({'a':range(1,5), 'b':['a','b','c','d']})
df2 = df.iloc[[0, -1]]

print df2

   a  b
0  1  a
3  4  d

it is very simply. Just write your php value code between textarea tag.

<textarea id="contact_list"> <?php echo isset($_POST['contact_list']) ? $_POST['contact_list'] : '' ; ?> </textarea>

Yes. For that ensure that you declare the worksheet

For example

Previous Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet3")

    Debug.Print ws.Cells(23, 4).Value
End Sub

New Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet4")

    Debug.Print ws.Cells(23, 4).Value
End Sub

Take a look at the new Spatial data-types that were introduced in SQL Server 2008. They are designed for this kind of task and make indexing and querying much easier and more efficient.

I already had committed the folder before and want to remove the directory in the history as well.

I did the following:

Add folder to .gitignore:

echo Folder_Name/ >> .gitignore

Remove from all commits:

git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch Folder_Name/' --prune-empty --tag-name-filter cat -- --all

remove the refs from the old commits:

git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

Ensure all old refs are fully removed

rm -Rf .git/logs .git/refs/original

Perform a garbage collection

git gc --prune=all --aggressive

push you changes to the online repository:

git push

You are done here.

But you can to the following to push all the changes to all branches with: But be careful with this command!

git push origin --all --force
git push origin --tags --force

After that the folder was removed from git, but was not deleted from local disk.

The init(frame:) version is the default initializer. You must call it only after initializing your instance variables. If this view is being reconstituted from a Nib then your custom initializer will not be called, and instead the init?(coder:) version will be called. Since Swift now requires an implementation of the required init?(coder:), I have updated the example below and changed the let variable declarations to var and optional. In this case, you would initialize them in awakeFromNib() or at some later time.

class TestView : UIView {
    var s: String?
    var i: Int?
    init(s: String, i: Int) {
        self.s = s
        self.i = i
        super.init(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

}

this is just a shot in the dark : when you call connect without a bind first, the system allocates your local port, and if you have multiple threads connecting and disconnecting it could possibly try to allocate a port already in use. the kernel source file inet_connection_sock.c hints at this condition. just as an experiment try doing a bind to a local port first, making sure each bind/connect uses a different local port number.

I have solved the issue by using UINavigationController when presenting. In MainVC, when presenting VC1

let vc1 = VC1()
let navigationVC = UINavigationController(rootViewController: vc1)
self.present(navigationVC, animated: true, completion: nil)

In VC1, when I would like to show VC2 and dismiss VC1 in same time (just one animation), I can have a push animation by

let vc2 = VC2()
self.navigationController?.setViewControllers([vc2], animated: true)

And in VC2, when close the view controller, as usual we can use:

self.dismiss(animated: true, completion: nil)

No Javascript required.

IE6 Internet Explorer 6

Percent only works for the width of an element, but height:100%; does not work without the correct code.

CSS

html, body { height:100%; } 

Then using a percentage works properly, and dynamically updates on window resize.

<img src="image.jpg" style="height:80%;">

You do not need a width attribute, the width scales proportionately as the browser window size is changed.

And this little gem, is in case the image is scaled up, it will not look (overly) blocky (it interpolates).

img { -ms-interpolation-mode: bicubic; }

If you want to guard against non-terminated strings, which can cause all sorts of problems, copy your string like this:

char array1[18] = {"abcdefg"};
char array2[18];

size_t destination_size = sizeof (array2);

strncpy(array2, array1, destination_size);
array2[destination_size - 1] = '\0';

That last line is actually important, because strncpy() does not always null terminate strings. (If the destination buffer is too small to contain the whole source string, sntrcpy() will not null terminate the destination string.)

The manpage for strncpy() even states "Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not be null-terminated."

The reason strncpy() behaves this somewhat odd way, is because it was not actually originally intended as a safe way to copy strings.

Another way is to use snprintf() as a safe replacement for strcpy():

snprintf(array2, destination_size, "%s", array1);

I generated the "ssh" key again and added to my git account. This worked for me.

Please find following commands to generate the "ssh-key":

$ ssh-keygen -t rsa -b 4096 -C "[email protected]"

-> This creates a new ssh key, using the provided email as a label.

Generating public/private rsa key pair.

-> When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

Enter a file in which to save the key (/home/you/.ssh/id_rsa): [Press enter]

-> At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases"

Enter passphrase (empty for no passphrase): [Type a passphrase]

Enter same passphrase again: [Type passphrase again]

-> Your key is generated, to copy the key:

$ sudo cat /root/.ssh/id_rsa-pub

Hope this works!

Firebug seems to allow you to do that.

There is a difference between click() and submit().

submit() submits the form and executes the url that is given by the "action" attribute. If you have any javascript-function or jquery-plugin running to submit the form e.g. via ajax, submit() will ignore it. With click() the javascript-functions will be executed.

As per the HTML you have provided:

<tr>
  <td>abc</td>
  <td>&nbsp;</td>
</tr>

To locate the node with the string   you can use either of the following xpath based solutions:

• Using text():

  "//td[text()='\u00A0']"
  

• Using contains():

  "//td[contains(., '\u00A0')]"
  

However, ideally you may like to avoid the NO-BREAK SPACE character and use either of the following Locator Strategies:

• Using the parent <tr> node and following-sibling:

  "//tr//following-sibling::td[2]"
  

• Using starts-with():

  "//tr//td[last()]"
  

• Using the preceeding <td> node and followingnode andfollowing-sibling`:

  "//td[text()='abc']//following::td[1]"

Unicode Character 'NO-BREAK SPACE' (U+00A0)

To answer the second part of your question - there are no pointers in PHP.

When working with objects, you generally pass by reference rather than by value - so in some ways this operates like a pointer, but is generally completely transparent.

This does depend on the version of PHP you are using.

robotex tools which are free will let you do this but they make you enter the ip of the domain first:

1. find out the ip (there's a good ff plugin which does this but I can't post the link cos this is my first post here!)
2. do an ip search on robotex: http://www.robtex.com/ip/
3. in the results page that follows click on the domain you're interested in>
4. you are taken to a page that lists all subdomains + a load of other information such as mail server info

Javascript arrays have a length property. Use it like this:

st.itemb.length

Wanted to post this as a comment as a side note to the accepted answer, but that got a bit unclear. So purely as a side note:

If you have no need for the objects themselves and you want to have your project clear of further unused classes, you can parse with something like:

var list = JObject.Parse(json)["People"].Select(el => new { FirstName = (string)el["FirstName"], LastName = (string)el["LastName"] }).ToList();

var firstNames = list.Select(p => p.FirstName).ToList();
var lastNames = list.Select(p => p.LastName).ToList();

Even when using a strongly typed person class, you can still skip the root object by creating a list with JObject.Parse(json)["People"].ToObject<List<Person>>() Of course, if you do need to reuse the objects, it's better to create them from the start. Just wanted to point out the alternative ;)

This will delete all the files in a directory (and below) that are size zero.

find /tmp -size  0 -print -delete

If you just want a particular file;

if [ ! -s /tmp/foo ] ; then
  rm /tmp/foo
fi

Referring to the WHATWG (Writing a form's user interface) it is not wrong to put the input field inside the label. This saves you code because the for attribute from the label is no longer needed.

You can also Use below method if you have to replace string between specific index

def Replace_Substring_Between_Index(singleLine,stringToReplace='',startPos=0,endPos=1):
    try:
       singleLine = singleLine[:startPos]+stringToReplace+singleLine[endPos:]
    except Exception as e:
        exception="There is Exception at this step while calling replace_str_index method, Reason = " + str(e)
        BuiltIn.log_to_console(exception)
    return singleLine

In that particular example, the error it's because of the GO after the use statements. The GO statements resets the environment, so no user variables exists. They must be declared again. And the answer to the global variables question is No, does not exists global variables at least Sql server versions equal or prior to 2008. I cannot assure the same for newer sql server versions.

The .htaccess is either in the root-directory of your webpage or in the directory you want to protect.

Make sure to make them visible in your filesystem, because AFAIK (I'm no unix expert either) files starting with a period are invisible by default on unix-systems.

Here's an Add to Calendar service to serve the purpose for adding an event on

1. Apple Calendar
2. Google Calendar
3. Outlook
4. Outlook Online
5. Yahoo! Calendar

The "Add to Calendar" button for events on websites and calendars is easy to install, language independent, time zone and DST compatible. It works perfectly in all modern browsers, tablets and mobile devices, and with Apple Calendar, Google Calendar, Outlook, Outlook.com and Yahoo Calendar.

<div title="Add to Calendar" class="addeventatc">
    Add to Calendar

Update : In angular 7, they are the same as 6

In angular 6

the complete answer found in live example

  /** POST: add a new hero to the database */
  addHero (hero: Hero): Observable<Hero> {
 return this.http.post<Hero>(this.heroesUrl, hero, httpOptions)
  .pipe(
    catchError(this.handleError('addHero', hero))
  );
}
  /** GET heroes from the server */
 getHeroes (): Observable<Hero[]> {
return this.http.get<Hero[]>(this.heroesUrl)
  .pipe(
    catchError(this.handleError('getHeroes', []))
  );
}

it's because of pipeable/lettable operators which now angular is able to use tree-shakable and remove unused imports and optimize the app

some rxjs functions are changed

do -> tap
catch -> catchError
switch -> switchAll
finally -> finalize

more in MIGRATION

and Import paths

For JavaScript developers, the general rule is as follows:

rxjs: Creation methods, types, schedulers and utilities

import { Observable, Subject, asapScheduler, pipe, of, from, interval, merge, fromEvent } from 'rxjs';

rxjs/operators: All pipeable operators:

import { map, filter, scan } from 'rxjs/operators';

rxjs/webSocket: The web socket subject implementation

import { webSocket } from 'rxjs/webSocket';

rxjs/ajax: The Rx ajax implementation

import { ajax } from 'rxjs/ajax';

rxjs/testing: The testing utilities

import { TestScheduler } from 'rxjs/testing';

and for backward compatability you can use rxjs-compat

Why make it difficult and hassle with locks? Use Dispatch Barriers.

A dispatch barrier creates a synchronization point within a concurrent queue.

While it’s running, no other block on the queue is allowed to run, even if it’s concurrent and other cores are available.

If that sounds like an exclusive (write) lock, it is. Non-barrier blocks can be thought of as shared (read) locks.

As long as all access to the resource is performed through the queue, barriers provide very cheap synchronization.

this is easy,
if you use .htaccess , check http: for https: ,
if you use codeigniter, check config : url_base -> you url http change for https.....
I solved my problem.

one elegant way to do this is to represent items in the list as string holding a dot separated list of parents, and finally a value:

server.port=90
server.hostname=localhost
client.serverport=90
client.database.port=1234
client.database.host=localhost

When assembling a tree, you would end up with something like:

server:
  port: 90
  hostname: localhost
client:
  serverport=1234
  database:
    port: 1234
    host: localhost

I have a configuration library that implements this override configuration (tree) from command line arguments (list). The algorithm to add a single item to the list to a tree is here.

As stated before - VueJS simply can't track those operations(array elements assignment). All operations that are tracked by VueJS with array are here. But I'll copy them once again:

• push()
• pop()
• shift()
• unshift()
• splice()
• sort()
• reverse()

During development, you face a problem - how to live with that :).

push(), pop(), shift(), unshift(), sort() and reverse() are pretty plain and help you in some cases but the main focus lies within the splice(), which allows you effectively modify the array that would be tracked by VueJs. So I can share some of the approaches, that are used the most working with arrays.

You need to replace Item in Array:

// note - findIndex might be replaced with some(), filter(), forEach() 
// or any other function/approach if you need 
// additional browser support, or you might use a polyfill
const index = this.values.findIndex(item => {
          return (replacementItem.id === item.id)
        })
this.values.splice(index, 1, replacementItem)

Note: if you just need to modify an item field - you can do it just by:

this.values[index].itemField = newItemFieldValue

And this would be tracked by VueJS as the item(Object) fields would be tracked.

You need to empty the array:

this.values.splice(0, this.values.length)

Actually you can do much more with this function splice() - w3schools link You can add multiple records, delete multiple records, etc.

Vue.set() and Vue.delete()

Vue.set() and Vue.delete() might be used for adding field to your UI version of data. For example, you need some additional calculated data or flags within your objects. You can do this for your objects, or list of objects(in the loop):

 Vue.set(plan, 'editEnabled', true) //(or this.$set)

And send edited data back to the back-end in the same format doing this before the Axios call:

 Vue.delete(plan, 'editEnabled') //(or this.$delete)

One thing to keep in mind is that the relevant path here is the path relative to the file system location of your class... in your case TestGameTable.class. It is not related to the location of the TestGameTable.java file.
I left a more detailed answer here... where is resource actually located

you may also want to remove the 0 at the beginning of the input... I simply add an if block to Mordred answer above because I cannot make a comment yet...

  app.directive('numericOnly', function() {
    return {
      require: 'ngModel',
      link: function(scope, element, attrs, modelCtrl) {

          modelCtrl.$parsers.push(function (inputValue) {
              var transformedInput = inputValue ? inputValue.replace(/[^\d.-]/g,'') : null;

              if (transformedInput!=inputValue) {
                  modelCtrl.$setViewValue(transformedInput);
                  modelCtrl.$render();
              }
              //clear beginning 0
              if(transformedInput == 0){
                modelCtrl.$setViewValue(null);
                modelCtrl.$render();
              }
              return transformedInput;
          });
      }
    };
  })

git diff branch_1..branch_2

That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:

git diff branch_1...branch_2

If you're using zsh, you can use multiple redirections, so you don't even need tee:

./cmd 1>&1 2>&2 1>out_file 2>err_file

Here you're simply redirecting each stream to itself and the target file.

Full example

% (echo "out"; echo "err">/dev/stderr) 1>&1 2>&2 1>/tmp/out_file 2>/tmp/err_file
out
err
% cat /tmp/out_file
out
% cat /tmp/err_file
err

Note that this requires the MULTIOS option to be set (which is the default).

MULTIOS

Perform implicit tees or cats when multiple redirections are attempted (see Redirection).

Tried all the above, did some research of my own resulting in the following solution for rendering linefeed escape chars:

string = string.replace("\\\n", System.getProperty("line.separator"));

1. Using the replace method you need to filter escaped linefeeds (e.g. '\\n')

2. Only then each instance of line feed '\n' escape chars gets rendered into the actual linefeed

For this example I used a Google Apps Scripting noSQL database (ScriptDb) with JSON formatted data.

Cheers :D

There is of course a lubridate solution for this:

library(lubridate)
date <- "2009-10-01"

ymd(date) - 5
# [1] "2009-09-26"

is the same as

ymd(date) - days(5)
# [1] "2009-09-26"

Other time formats could be:

ymd(date) - months(5)
# [1] "2009-05-01"

ymd(date) - years(5)
# [1] "2004-10-01"

ymd(date) - years(1) - months(2) - days(3)
# [1] "2008-07-29"

phpBB uses a few functions to parse their files. They are rather well-commented (what an exception!) so you can easily know what they do (I got this solution from http://www.frihost.com/forums/vt-8194.html). here is the solution an I've used it a lot:

1. Define the expected and desired output for a normal case, with correct input.

2. Now, implement the test by declaring a class, name it anything (Usually something like TestAddingModule), and add the testAdd method to it (i.e. like the one below) :

   • Write a method, and above it add the @Test annotation.
   • In the method, run your binary sum and assertEquals(expectedVal,calculatedVal).

   • Test your method by running it (in Eclipse, right click, select Run as ? JUnit test).

     //for normal addition 
     @Test
     public void testAdd1Plus1() 
     {
         int x  = 1 ; int y = 1;
         assertEquals(2, myClass.add(x,y));
     }
     

3. Add other cases as desired.

   • Test that your binary sum does not throw a unexpected exception if there is an integer overflow.

   • Test that your method handles Null inputs gracefully (example below).

     //if you are using 0 as default for null, make sure your class works in that case.
     @Test
     public void testAdd1Plus1() 
     {
         int y = 1;
         assertEquals(0, myClass.add(null,y));
     }
     

Use groupby and idxmax methods:

1. transfer col date to datetime:

   df['date']=pd.to_datetime(df['date'])
   

2. get the index of max of column date, after groupyby ad_id:

   idx=df.groupby(by='ad_id')['date'].idxmax()
   

3. get the wanted data:

   df_max=df.loc[idx,]
   

Out[54]:

ad_id  price       date
7     22      2 2018-06-11
6     23      2 2018-06-22
2     24      2 2018-06-30
3     28      5 2018-06-22

Try font-weight:normal;

h1 {
    font-weight: normal;
}

Both functions use the os.path.split(path) function to split the pathname path into a pair; (head, tail).

The os.path.dirname(path) function returns the head of the path.

E.g.: The dirname of '/foo/bar/item' is '/foo/bar'.

The os.path.basename(path) function returns the tail of the path.

E.g.: The basename of '/foo/bar/item' returns 'item'

From: http://docs.python.org/2/library/os.path.html#os.path.basename

If you are using virtualenv, it is not as trivial to get the driver using the installer. What you can do then: install it as described by Devon. Then copy over cx_Oracle.pyd and the cx_Oracle-XXX.egg-info folder from Python\Lib\site-packages into the Lib\site-packages from your virtual env. Of course, also here, architecture and version are important.

From a controller you can also return an Object/Array and it will be sent as a JSON response (including the correct HTTP headers).

public function show($id)
{
    return Customer::find($id);
}

git diff path/file.css | grep -E "^\+" | grep -v '+++ b/' | cut -c 2-

• grep -E "^\+" is from previous accepted answer, it is incomplete because leaves non-source stuff
• grep -v '+++ b' removes non-source line with file name of later version
• cut -c 2- removes column of + signs, also may use sed 's/^\+//'

comm or sdiff were not an option because of git.

<?php

$var1 = "Line 1 info blah blah <br /> Line 2 info blah blah";
$var1 = str_replace("<br />", "\n", $var1);

?>

<textarea><?php echo $var1; ?></textarea>

The way to do this is by adding tabindex="-1". By adding this to a specific element, it becomes unreachable by the keyboard navigation. There is a great article here that will help you further understand tabindex.

If you find that you do not have JDK installed. Go to your android terminal and navigate to the bin folder of JRE that comes with Android Studio.

C:\Program Files\Android\Android Studio\jre\bin

and run the following command. Remember to replace USERNAME with your actual PC username.

keytool -list -v -keystore "C:\Users\USERNAME\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:

with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
    data = json.load(jsonfile)

The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.

The alternative is to read the data yourself and then pass it into json.loads().

if you want to shrink one slide for instance, add shapes to hide the unwanted background margins. you can set the shape color filling as the background (gray or black). It's "ugly" but it works

This function collect all matching sequences from string. In this example it takes all email addresses from string.

static final String EMAIL_PATTERN = "[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
        + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})";

public List<String> getAllEmails(String message) {      
    List<String> result = null;
    Matcher matcher = Pattern.compile(EMAIL_PATTERN).matcher(message);

    if (matcher.find()) {
        result = new ArrayList<String>();
        result.add(matcher.group());

        while (matcher.find()) {
            result.add(matcher.group());
        }
    }

    return result;
}

For message = "[email protected], <[email protected]>>>> [email protected]" it will create List of 3 elements.

If you need to run more than one daemon process, there's a suggestion in the Docker documentation to use Supervisord in an un-detached mode so all the sub-daemons will output to the stdout.

From another SO question, I discovered you can redirect the child processes output to the stdout. That way you can see all the output!

If you're using Atom editor, you can accomplish this by the ascii-tree package.

You can write the following tree:

root
+-- dir1
    +--file1
+-- dir2
    +-- file2

and convert it to the following by selecting it and pressing ctrl-alt-t:

root
+-- dir1
¦   +-- file1
+-- dir2
    +-- file2

Jupyter under the WinPython environment has a batch file in the scripts folder called:

make_working_directory_be_not_winpython.bat

You need to edit the following line in it:

echo WINPYWORKDIR = %%HOMEDRIVE%%%%HOMEPATH%%\Documents\WinPython%%WINPYVER%%\Notebooks>>"%winpython_ini%"

replacing the Documents\WinPython%%WINPYVER%%\Notebooks part with your folder address.

Notice that the %%HOMEDRIVE%%%%HOMEPATH%%\ part will identify the root and user folders (i.e. C:\Users\your_name\) which will allow you to point different WinPython installations on separate computers to the same cloud storage folder (e.g. OneDrive), accessing and working with the same files from different machines. I find that very useful.

Look at the System.IO.Directory class and the static method GetFiles. It has an overload that accepts a path and a search pattern. Example:

 string[] files = System.IO.Directory.GetFiles(path, "*.txt");

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

I'm assuming c++ here. If you're using c#, the answer is probably the same, but the syntax will be a bit different. The enum is a set of int values. It's not an object, so you shouldn't be setting it to null. Setting something to null means you are pointing a pointer to an object to address zero. You can't really do that with an int. What you want to do with an int is to set it to a value you wouldn't normally have it at so that you can tel if it's a good value or not. So, set your colour to -1

Color color = -1;

Or, you can start your enum at 1 and set it to zero. If you set the colour to zero as it is right now, you will be setting it to "red" because red is zero in your enum.

So,

enum Color {
red =1
blue,
green
}
//red is 1, blue is 2, green is 3
Color mycolour = 0;

Select all, then:

Windows / Linux:

Ctrl+Shift+p

then type "indent"

Mac:

Shift+Command+p

then type "indent"

Some browsers use keyCode, others use which. If you're using jQuery, you can reliably use which as jQuery standardizes things. Actually,

$('#searchbox input').bind('keypress', function(e) {
    if(e.keyCode==13){

    }
});

Are you familiar with the DataSet class?

The DataSet can also load XML documents and you may find it easier to iterate.

http://msdn.microsoft.com/en-us/library/system.data.dataset.readxml.aspx

DataSet dt = new DataSet();
dt.ReadXml(@"c:\test.xml");

In 1.0, the functionality was bound to ( and tab and shift-tab, in 2.0 tab was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. ( was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab.

So press Shift-Tab.

If you are using a JetBrains IDE (anything IntelliJ based), you can recover even your uncommited changes via their "Local History" feature.

Right-click on your top-level directory in your file tree, find "Local History" in the context menu, and choose "Show History". This will open up a view where your recent edits can be found, and once you have found the revision you want to go back to, right click on it and click "Revert".

You can use the function RESHAPE:

B = reshape(A.',1,[]);

It's rather easy to add some syntactical sugar that allows one to compose strings on the fly in a stream-like way

#include <string>
#include <sstream>

struct strmake {
    std::stringstream s;
    template <typename T> strmake& operator << (const T& x) {
        s << x; return *this;
    }   
    operator std::string() {return s.str();}
};

Now you may append whatever you want (provided that an operator << (std::ostream& ..) is defined for it) to strmake() and use it in place of an std::string.

Example:

#include <iostream>

int main() {
    std::string x =
      strmake() << "Current time is " << 5+5 << ":" << 5*5 << " GST";
    std::cout << x << std::endl;
}

I believe you need something similar to the following:

<script type="text/javascript">
var count;
function increment(){
    count++;
}
</script>

...

and

<input type="button" onClick="increment()" value="Increment"/>

or

<input type="button" onClick="count++" value="Increment"/>

I recommand the following article : Hit Region Detection For HTML5 Canvas And How To Listen To Click Events On Canvas Shapes which goes through various situations.

However, it does not cover the addHitRegion API, which must be the best way (using math functions and/or comparisons is quite error prone). This approach is detailed on developer.mozilla

Wouldn't be recommending to use TelephonyManager as it requires the app to require READ_PHONE_STATE permission during runtime.

<uses-permission android:name="android.permission.READ_PHONE_STATE"/> 

Should be using Google's Play Service for Authentication, and it will able to allow User to select which phoneNumber to use, and handles multiple SIM cards, rather than us trying to guess which one is the primary SIM Card.

implementation "com.google.android.gms:play-services-auth:$play_service_auth_version"

fun main() {
    val googleApiClient = GoogleApiClient.Builder(context)
        .addApi(Auth.CREDENTIALS_API).build()

    val hintRequest = HintRequest.Builder()
        .setPhoneNumberIdentifierSupported(true)
        .build()

    val hintPickerIntent = Auth.CredentialsApi.getHintPickerIntent(
        googleApiClient, hintRequest
    )

    startIntentSenderForResult(
        hintPickerIntent.intentSender, REQUEST_PHONE_NUMBER, null, 0, 0, 0
    )
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    when (requestCode) {
        REQUEST_PHONE_NUMBER -> {
            if (requestCode == Activity.RESULT_OK) {
                val credential = data?.getParcelableExtra<Credential>(Credential.EXTRA_KEY)
                val selectedPhoneNumber = credential?.id
            }
        }
    }
}

Or you can use initialize list:

revenue.push_back({"string", map[i].second});

In the related question you posted, we already have a way to achieve that in plain javascript, so we only need to get the js reference to the dom node we want to scroll.

The ref attribute can be used to declare reference to html elements to make them available in vue's component methods.

Or, if the method in the component is a handler for some UI event, and the target is related to the div you want to scroll in space, you can simply pass in the event object along with your wanted arguments, and do the scroll like scroll(event.target.nextSibling).

if you use jquery you can do like this. from this site Placeholder with Jquery

$('[placeholder]').parents('form').submit(function() {
  $(this).find('[placeholder]').each(function() {
    var input = $(this);
    if (input.val() == input.attr('placeholder')) {
      input.val('');
    }
  })
});

these are the alternate links

1. Placeholder jquery library
2. HTML5 polyfills -- go for placeholder section

Decide if you need an immutable object or not.

If you put public properties in your class, the state of every instance can be changed at every time in your code. So your class could be like this:

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public Person(){}
    public Person(string name, int age)
    {
        Name = name;
        Age = age;
    }
    //Other properties, methods, events...
}

In that case, having a Person(string name, int age) constructor is not so useful.

The second option is to implement an immutable type. For example:

public class Person
{
    public string Name { get; private set; }
    public int Age { get; private set; }

    public Person(string name, int age)
    {
        Name = name;
        Age = age;
    }
    //Other properties, methods, events...
}

Now you have a constructor that sets the state for the instance, once, at creation time. Note that now setters for properties are private, so you can't change the state after your object is instantiated.

A best practice is to define classes as immutable every time if possible. To understand advantages of immutable classes I suggest you read this article.

Even though you define android:onClick = "DoIt" in XML, you need to make sure your activity (or view context) has public method defined with exact same name and View as parameter. Android wires your definitions with this implementation in activity. At the end, implementation will have same code which you wrote in anonymous inner class. So, in simple words instead of having inner class and listener attachement in activity, you will simply have a public method with implementation code.

You need to change your Ajax call to

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    contentType: "json",
    processData: false,
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

change the dataType to contentType and add the processData option.

To retrieve the JSON payload from your controller, use:

dd(json_decode($request->getContent(), true));

instead of

dd($request->all());

You can "cast" to number using the Number constructor..

var number = new Number("8"); // 8 number

You can also call parseInt builtin function:

var number = parseInt("153"); // 153 number

IteratorUtils from commons-collections may help (although they don't support generics in the latest stable version 3.2.1):

@SuppressWarnings("unchecked")
Collection<Type> list = IteratorUtils.toList(iterable.iterator());

Version 4.0 (which is in SNAPSHOT at this moment) supports generics and you can get rid of the @SuppressWarnings.

Update: Check IterableAsList from Cactoos.

I would suggest:

DECLARE @sqlStatement nvarchar(MAX),
        @tableName nvarchar(50) = 'TripEvent',
        @columnName nvarchar(50) = 'CreatedDate';

SELECT                  @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
        FROM            sys.default_constraints AS dc
            LEFT JOIN   sys.columns AS sc
                ON      (dc.parent_column_id = sc.column_id)
        WHERE           dc.parent_object_id = OBJECT_ID(@tableName)
        AND         type_desc = 'DEFAULT_CONSTRAINT'
        AND         sc.name = @columnName
PRINT'   ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+';  '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement

Auto reload with target of your choice. In this case target is _self set to every 5 minutes.

300000 milliseconds = 300 seconds = 5 minutes

as 60000 milliseconds = 60 seconds = 1 minute.

This is how you do it:

<script type="text/javascript">
function load()
{
setTimeout("window.open('http://YourPage.com', '_self');", 300000);
}
</script>
<body onload="load()">

Or this if it is the same page to reload itself:

<script type="text/javascript">
function load()
{
setTimeout("window.open(self.location, '_self');", 300000);
}
</script>
<body onload="load()">

Use 'as' declaration:

const data = JSON.parse(response.data) as MyClass;

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

This comes in useful when you have global variables. You declare the existence of global variables in a header, so that each source file that includes the header knows about it, but you only need to “define” it once in one of your source files.

To clarify, using extern int x; tells the compiler that an object of type int called x exists somewhere. It's not the compilers job to know where it exists, it just needs to know the type and name so it knows how to use it. Once all of the source files have been compiled, the linker will resolve all of the references of x to the one definition that it finds in one of the compiled source files. For it to work, the definition of the x variable needs to have what's called “external linkage”, which basically means that it needs to be declared outside of a function (at what's usually called “the file scope”) and without the static keyword.

header:

#ifndef HEADER_H
#define HEADER_H

// any source file that includes this will be able to use "global_x"
extern int global_x;

void print_global_x();

#endif

source 1:

#include "header.h"

// since global_x still needs to be defined somewhere,
// we define it (for example) in this source file
int global_x;

int main()
{
    //set global_x here:
    global_x = 5;

    print_global_x();
}

source 2:

#include <iostream>
#include "header.h"

void print_global_x()
{
    //print global_x here:
    std::cout << global_x << std::endl;
}

Bash documentation says that every time $RANDOM is referenced, a random number between 0 and 32767 is returned. If we sum two consecutive references, we get values from 0 to 65534, which covers the desired range of 63001 possibilities for a random number between 2000 and 65000.

To adjust it to the exact range, we use the sum modulo 63001, which will give us a value from 0 to 63000. This in turn just needs an increment by 2000 to provide the desired random number, between 2000 and 65000. This can be summarized as follows:

port=$((((RANDOM + RANDOM) % 63001) + 2000))

Testing

# Generate random numbers and print the lowest and greatest found
test-random-max-min() {
    max=2000
    min=65000
    for i in {1..10000}; do
        port=$((((RANDOM + RANDOM) % 63001) + 2000))
        echo -en "\r$port"
        [[ "$port" -gt "$max" ]] && max="$port"
        [[ "$port" -lt "$min" ]] && min="$port"
    done
    echo -e "\rMax: $max, min: $min"
}

# Sample output
# Max: 64990, min: 2002
# Max: 65000, min: 2004
# Max: 64970, min: 2000

Correctness of the calculation

Here is a full, brute-force test for the correctness of the calculation. This program just tries to generate all 63001 different possibilities randomly, using the calculation under test. The --jobs parameter should make it run faster, but it's not deterministic (total of possibilities generated may be lower than 63001).

test-all() {
    start=$(date +%s)
    find_start=$(date +%s)
    total=0; ports=(); i=0
    rm -f ports/ports.* ports.*
    mkdir -p ports
    while [[ "$total" -lt "$2" && "$all_found" != "yes" ]]; do
        port=$((((RANDOM + RANDOM) % 63001) + 2000)); i=$((i+1))
        if [[ -z "${ports[port]}" ]]; then
            ports["$port"]="$port"
            total=$((total + 1))
            if [[ $((total % 1000)) == 0 ]]; then
                echo -en "Elapsed time: $(($(date +%s) - find_start))s \t"
                echo -e "Found: $port \t\t Total: $total\tIteration: $i"
                find_start=$(date +%s)
            fi
        fi
    done
    all_found="yes"
    echo "Job $1 finished after $i iterations in $(($(date +%s) - start))s."
    out="ports.$1.txt"
    [[ "$1" != "0" ]] && out="ports/$out"
    echo "${ports[@]}" > "$out"
}

say-total() {
    generated_ports=$(cat "$@" | tr ' ' '\n' | \sed -E s/'^([0-9]{4})$'/'0\1'/)
    echo "Total generated: $(echo "$generated_ports" | sort | uniq | wc -l)."
}
total-single() { say-total "ports.0.txt"; }
total-jobs() { say-total "ports/"*; }
all_found="no"
[[ "$1" != "--jobs" ]] && test-all 0 63001 && total-single && exit
for i in {1..1000}; do test-all "$i" 40000 & sleep 1; done && wait && total-jobs

For determining how many iterations are needed to get a given probability p/q of all 63001 possibilities having been generated, I believe we can use the expression below. For example, here is the calculation for a probability greater than 1/2, and here for greater than 9/10.

I had a problem with this kind of sql, I was giving empty list in IN clause(always check the list if it is not empty). Maybe my practice will help somebody.

Do git help gitignore

You will get the help page with following line:

A line starting with # serves as a comment.

The port 8005 is used as service port. You can send a shutdown command (a configurable password) to that port. It will not "speak" HTTP, so you cannot use your browser to connect.

The default port for delivering web-content is 8080.

But there may be other applications listen to that port. So your tomcat may not start, if the port is not available.

You asked "How do you know, if tomcat server is installed on your PC?". The answer to that question is: You can't

You can't determine, if it is installed, because it may be only extracted from a ZIP archive or packaged within another application (Like JBoss AS (I think)).

It's Date.getTime().

I find that the "solution" of just increasing the timeouts obscures what's really going on here, which is either

1. Your code and/or network calls are way too slow (should be sub 100 ms for a good user experience)
2. The assertions (tests) are failing and something is swallowing the errors before Mocha is able to act on them.

You usually encounter #2 when Mocha doesn't receive assertion errors from a callback. This is caused by some other code swallowing the exception further up the stack. The right way of dealing with this is to fix the code and not swallow the error.

When external code swallows your errors

In case it's a library function that you are unable to modify, you need to catch the assertion error and pass it onto Mocha yourself. You do this by wrapping your assertion callback in a try/catch block and pass any exceptions to the done handler.

it('should not fail', function (done) { // Pass reference here!

  i_swallow_errors(function (err, result) {
    try { // boilerplate to be able to get the assert failures
      assert.ok(true);
      assert.equal(result, 'bar');
      done();
    } catch (error) {
      done(error);
    }
  });
});

This boilerplate can of course be extracted into some utility function to make the test a little more pleasing to the eye:

it('should not fail', function (done) { // Pass reference here!
    i_swallow_errors(handleError(done, function (err, result) {
        assert.equal(result, 'bar');
    }));
});

// reusable boilerplate to be able to get the assert failures
function handleError(done, fn) {
    try { 
        fn();
        done();
    } catch (error) {
        done(error);
    }
}

Speeding up network tests

Other than that I suggest you pick up the advice on starting to use test stubs for network calls to make tests pass without having to rely on a functioning network. Using Mocha, Chai and Sinon the tests might look something like this

describe('api tests normally involving network calls', function() {

    beforeEach: function () {
        this.xhr = sinon.useFakeXMLHttpRequest();
        var requests = this.requests = [];

        this.xhr.onCreate = function (xhr) {
            requests.push(xhr);
        };
    },

    afterEach: function () {
        this.xhr.restore();
    }


    it("should fetch comments from server", function () {
        var callback = sinon.spy();
        myLib.getCommentsFor("/some/article", callback);
        assertEquals(1, this.requests.length);

        this.requests[0].respond(200, { "Content-Type": "application/json" },
                                 '[{ "id": 12, "comment": "Hey there" }]');
        expect(callback.calledWith([{ id: 12, comment: "Hey there" }])).to.be.true;
    });

});

See Sinon's nise docs for more info.

Scan the string for ://. If it does not have it, prepend http:// to the string... Everything else just use the string as is.

This will work unless you have a rubbish input string.

Ok it turns out I was doing something stupid. I hadn't appended the new file name to the path.

I had

rootDirectory = "C:\\safesite_documents"

but it should have been

rootDirectory = "C:\\safesite_documents\\newFile.jpg" 

Sorry it was a stupid mistake as always.

You can try using a simple library like

After installing via gradle and adding permissions initiate SmsVerifyCatcher in method like onCreate activity:

    smsVerifyCatcher = new SmsVerifyCatcher(this, new OnSmsCatchListener<String>() {
    @Override
    public void onSmsCatch(String message) {
        String code = parseCode(message);//Parse verification code
        etCode.setText(code);//set code in edit text
        //then you can send verification code to server
    }
});

Also, override activity lifecicle methods:

  @Override
protected void onStart() {
    super.onStart();
    smsVerifyCatcher.onStart();
}

@Override
protected void onStop() {
    super.onStop();
    smsVerifyCatcher.onStop();
}

/**
 * need for Android 6 real time permissions
 */
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    smsVerifyCatcher.onRequestPermissionsResult(requestCode, permissions, grantResults);
}


public String parseCode(String message) {
    Pattern p = Pattern.compile("\\b\\d{4}\\b");
    Matcher m = p.matcher(message);
    String code = "";
    while (m.find()) {
        code = m.group(0);
    }
    return code;
}

I actually found something that worked for me. It converts the text to binary and then to UTF8.

Source Text that has encoding issues: If ‘Yes’, what was your last

SELECT CONVERT(CAST(CONVERT(
    (SELECT CONVERT(CAST(CONVERT(english_text USING LATIN1) AS BINARY) USING UTF8) AS res FROM m_translation WHERE id = 865) 
USING LATIN1) AS BINARY) USING UTF8) AS 'result';

Corrected Result text: If ‘Yes’, what was your last

My source was wrongly encoded twice so I had two do it twice. For one time you can use:

SELECT CONVERT(CAST(CONVERT(column_name USING latin1) AS BINARY) USING UTF8) AS res FROM m_translation WHERE id = 865;

Please excuse me for any formatting mistakes

Try following or check demo disabled and readonly

$('#dropUnit').is(':disabled') //Returns bool
$('#dropUnit').attr('readonly') == "readonly"  //If Condition

You can check jQuery FAQ .

As per dart 2.6

The optional onError parameter of int.parse is deprecated. Therefore, you should use int.tryParse instead.

Note: The same applies to double.parse. Therefore, use double.tryParse instead.

  /**
   * ...
   *
   * The [onError] parameter is deprecated and will be removed.
   * Instead of `int.parse(string, onError: (string) => ...)`,
   * you should use `int.tryParse(string) ?? (...)`.
   *
   * ...
   */
  external static int parse(String source, {int radix, @deprecated int onError(String source)});

The difference is that int.tryParse returns null if the source string is invalid.

  /**
   * Parse [source] as a, possibly signed, integer literal and return its value.
   *
   * Like [parse] except that this function returns `null` where a
   * similar call to [parse] would throw a [FormatException],
   * and the [source] must still not be `null`.
   */
  external static int tryParse(String source, {int radix});

So, in your case it should look like:

// Valid source value
int parsedValue1 = int.tryParse('12345');
print(parsedValue1); // 12345

// Error handling
int parsedValue2 = int.tryParse('');
if (parsedValue2 == null) {
  print(parsedValue2); // null
  //
  // handle the error here ...
  //
}

You mean you want to remove the version from parent block of B's pom, I think you can not do it, the groupId, artifactId, and version specified the parent's pom coordinate's, what you can omit is child's version.

It would be the highest available priority setting, and would usually only be used on box that was dedicated to running that specific program. It's actually high enough that it could cause starvation of the keyboard and mouse threads to the extent that they become unresponsive.

So basicly, if you have to ask, don't use it :)

it happen with me when i change properties of App.config to be Copy Always

and fix it by undo all my edits then build to make sure it worked

finally reset it again copy always and build it worked

Just for fun, here's a fairly safe way to assign "unassigned" to a variable. For this to have a collision would require someone to have added to the prototype for Object with exactly the same name as the randomly generated string. I'm sure the random string generator could be improved, but I just took one from this question: Generate random string/characters in JavaScript

This works by creating a new object and trying to access a property on it with a randomly generated name, which we are assuming wont exist and will hence have the value of undefined.

function GenerateRandomString() {
    var text = "";
    var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

    for (var i = 0; i < 50; i++)
        text += possible.charAt(Math.floor(Math.random() * possible.length));

    return text;
}

var myVar = {}[GenerateRandomString()];

I would do it like this:

int totalMinutes = (int)(end - start).TotalMinutes;

This typically stems from a bug in revision control system, or similar. This was a product from CVS, if a file was checked in from Windows to Unix server, and then checked out again...

In other words, it is just broken...

In addition to the above answer, this is the actual code:

[[UIDevice currentDevice] name];

previous solution have a bug in ip & net == net. Correct ip lookup is ip & netmask = net

bugfixed code:

import socket
import struct

def makeMask(n):
    "return a mask of n bits as a long integer"
    return (2L<<n-1) - 1

def dottedQuadToNum(ip):
    "convert decimal dotted quad string to long integer"
    return struct.unpack('L',socket.inet_aton(ip))[0]

def addressInNetwork(ip,net,netmask):
   "Is an address in a network"
   print "IP "+str(ip) + " NET "+str(net) + " MASK "+str(netmask)+" AND "+str(ip & netmask)
   return ip & netmask == net

def humannetcheck(ip,net):
        address=dottedQuadToNum(ip)
        netaddr=dottedQuadToNum(net.split("/")[0])
        netmask=makeMask(long(net.split("/")[1]))
        return addressInNetwork(address,netaddr,netmask)


print humannetcheck("192.168.0.1","192.168.0.0/24");
print humannetcheck("192.169.0.1","192.168.0.0/24");

Arrays.fill(). The method is overloaded for different data types, and there is even a variation that fills only a specified range of indices.

maytham-???i???, you can use this code to simulate input of file:

System.setIn(new FileInputStream("FILE_NAME"));

Or send file name as parameter and then put it into FileInputStream:

System.setIn(new FileInputStream(args[0]));

Sounds like you want to do an "upsert". MongoDB has built-in support for this. Pass an extra parameter to your update() call: {upsert:true}. For example:

key = {'key':'value'}
data = {'key2':'value2', 'key3':'value3'};
coll.update(key, data, upsert=True); #In python upsert must be passed as a keyword argument

This replaces your if-find-else-update block entirely. It will insert if the key doesn't exist and will update if it does.

Before:

{"key":"value", "key2":"Ohai."}

After:

{"key":"value", "key2":"value2", "key3":"value3"}

You can also specify what data you want to write:

data = {"$set":{"key2":"value2"}}

Now your selected document will update the value of "key2" only and leave everything else untouched.

You can try using simlinks, but in reverse.

React won't follow simlinks, but you can move something to the source directory, and create a simlink to it.

In the root of my project, I had a node server directory that had several schema files in it. I wanted to use them on the frontend, so I:

• moved the files /src
• in the termal, I cd'ed into where the schema files belonged in server
• ln -s SRC_PATH_OF_SCHEMA_FILE

This gave react what it was looking for, and node was perfectly happy including files through simlinks.

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

XML has only one definition for a comment:

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

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

In Eclipse, go to Window → Preferences → General → Network Connections. In the Active Provider combo box, choose "Manual". In the proxy entries table, for each entry click "Edit..." and supply your proxy host, port, username and password details.

Try:

EXEC sp_rename 'TableName.OldName', 'NewName', 'COLUMN'

Simply specify the version in your current pom. The version specified here will override other.

Forcing a version
A version will always be honoured if it is declared in the current POM with a particular version - however, it should be noted that this will also affect other poms downstream if it is itself depended on using transitive dependencies.

DateTime d = DateTime.Today.Date;
Console.WriteLine(d.ToShortDateString()); // outputs just date

if you want to compare dates, ignoring the time part, make an use of DateTime.Year and DateTime.DayOfYear properties.

code snippet

DateTime d1 = DateTime.Today;
DateTime d2 = DateTime.Today.AddDays(3);
if (d1.Year < d2.Year)
    Console.WriteLine("d1 < d2");
else
    if (d1.DayOfYear < d2.DayOfYear)
        Console.WriteLine("d1 < d2");

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

http://www.enterprisedb.com/products-services-training/products/postgres-enterprise-manager

Ninja edit disclaimer/notice: it seems that this user is affiliated with EnterpriseDB, as the linked Postgres Enterprise Manager website contains a video of one Dave Page.

Even though the question is quite fuzzy and the HTML snippet is quite limited, I suppose

.feature_desc {
    display: block;
}
.feature_desc:before {
    content: "";
    display: block;
}

might give you want you want to achieve without the <br/> element. Though it would help to see your CSS applied to these elements.

NOTE. The example above doesn't work in IE7 though.

Your explanation looks decent, but may be it looked like you were reading it all from a textbook? :-/

What I'm more bothered about is, how solid was your example? Did you bother to include almost all the differences between abstract and interfaces?

Personally, I would suggest this link: http://mindprod.com/jgloss/interfacevsabstract.html#TABLE

for an exhaustive list of differences..

Hope it helps you and all other readers in their future interviews

By using ''.join

list1 = ['1', '2', '3']
str1 = ''.join(list1)

Or if the list is of integers, convert the elements before joining them.

list1 = [1, 2, 3]
str1 = ''.join(str(e) for e in list1)

Simply do

SELECT birthdate, (YEAR(CURDATE())-YEAR(birthdate)) AS age FROM `member` 

birthdate is field name that keep birthdate name take CURDATE() turn to year by YEAR() command minus with YEAR() from the birthdate field

This method doesn't call the disambiguation dialog asking you to open either your app or a browser.

If you register the following in your Manifest

<manifest package="com.myApp" .. >
  <application ...>
    <activity ...>
      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data
          android:host="gallery"
          android:scheme="myApp" />
      </intent-filter>
    </activity>
    ..

and click this url from an email on your phone for example

<a href="intent://gallery?directLink=true#Intent;scheme=myApp;package=com.myApp;end"> 
  Click me 
</a>

then android will try to find an app with the package com.myApp that responds to your gallery intent and has a myApp scheme. In case it can't, it will take you to the store, looking for com.myApp, which should be your app.

crontab -e

add:

30 2 * * * /your/command

git log -1 --abbrev-commit

will also do it.

git log --abbrev-commit

will list the log entries with abbreviated SHA-1 checksum.

If the anonymous type causes trouble for you, you can create a simple data class:

public class PermissionsAndPages
{
     public ObjectPermissions Permissions {get;set}
     public Pages Pages {get;set}
}

and then in your query:

select new PermissionsAndPages { Permissions = op, Page = pg };

Then you can pass this around:

return queryResult.SingleOrDefault(); // as PermissionsAndPages

You can use a deadlock graph and gather the information you require from the log file.

The only other way I could suggest is digging through the information by using EXEC SP_LOCK (Soon to be deprecated), EXEC SP_WHO2 or the sys.dm_tran_locks table.

SELECT  L.request_session_id AS SPID, 
    DB_NAME(L.resource_database_id) AS DatabaseName,

    P.object_id AS LockedObjectId, 
    L.resource_type AS LockedResource, 
    L.request_mode AS LockType,
    ST.text AS SqlStatementText,        
    ES.login_name AS LoginName,
    ES.host_name AS HostName,
    TST.is_user_transaction as IsUserTransaction,
    AT.name as TransactionName,
    CN.auth_scheme as AuthenticationMethod

strcpy is only for C strings. For std::string you copy it like any C++ object.

std::string a = "text";
std::string b = a; // copy a into b

If you want to concatenate strings you can use the + operator:

std::string a = "text";
std::string b = "image";
a = a + b; // or a += b;

You can even do many at once:

std::string c = a + " " + b + "hello";

Although "hello" + " world" doesn't work as you might expect. You need an explicit std::string to be in there: std::string("Hello") + "world"

You may want to comment out the DL is deprecated, please use Fiddle warning at

C:\Ruby200\lib\ruby\2.0.0\dl.rb

since it’s annoying and you are not the irb/pry or some other gems code owner

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo implode('~',$array);
?>

and js

$(document).ready( function() {
$('#prev').click(function() {
  $.ajax({
  type: 'POST',
  url: 'ajax.php',
  data: 'id=testdata',
  cache: false,
  success: function(data) {
    result=data.split('~');
    $('#content1').html(result[0]);
  },
  });
});
});

It really depends on what algorithms you need to implement, there is no silver bullet (and that's shouldn't be a surprise... the general rule about programming is that there's no general rule ;-) ).

I often end up representing directed multigraphs using node/edge structures with pointers... more specifically:

struct Node
{
    ... payload ...
    Link *first_in, *last_in, *first_out, *last_out;
};

struct Link
{
    ... payload ...
    Node *from, *to;
    Link *prev_same_from, *next_same_from,
         *prev_same_to, *next_same_to;
};

In other words each node has a doubly-linked list of incoming links and a doubly-linked list of outgoing links. Each link knows from and to nodes and is at the same time in two different doubly-linked lists: the list of all links coming out from the same from node and the list of all links arriving at the same to node.

The pointers prev_same_from and next_same_from are used when following the chain of all the links coming out from the same node; the pointers prev_same_to and next_same_to are instead used when managing the chain of all the links pointing to the same node.

It's a lot of pointer twiddling (so unless you love pointers just forget about this) but query and update operations are efficient; for example adding a node or a link is O(1), removing a link is O(1) and removing a node x is O(deg(x)).

Of course depending on the problem, payload size, graph size, graph density this approach can be way overkilling or too much demanding for memory (in addition to payload you've 4 pointers per node and 6 pointers per link).

A similar structure full implementation can be found here.

Try this:

Sub GetColumns()

Dim lnRow As Long, lnCol As Long

lnRow = 3 'For testing

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

End Sub

Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

You need to intent your current context to another activity first with startActivity. After that you can finish your current activity from where you redirect.

 Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.

In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.

This creates backup files. E.g. sed -i -e 's/hello/hello world/' testfile for me, creates a backup file, testfile-e, in the same dir.

You can use LIKE instead of =. Without any wildcards this will have the same effect.

DECLARE @Village TABLE
        (CastleType TEXT)

INSERT INTO @Village
VALUES
  (
    'foo'
  )

SELECT *
FROM   @Village
WHERE  [CastleType] LIKE 'foo' 

text is deprecated. Changing to varchar(max) will be easier to work with.

Also how large is the data likely to be? If you are going to be doing equality comparisons you will ideally want to index this column. This isn't possible if you declare the column as anything wider than 900 bytes though you can add a computed checksum or hash column that can be used to speed this type of query up.

for i in range(10):
    print(i, end = ' ')

You can provide any delimiter to the end field (space, comma etc.)

This is for Python 3

you can use unlink to remove the symlink.

For Example:

cd ~/projects/node-redis 
npm link                 
cd ~/projects/node-bloggy
npm link redis             # links to your local redis

To reinstall from your package.json:

npm unlink redis
npm install

After trying several things, this worked for me:

• use the --publish=0.0.0.0:8080:8080 docker flag
• set the virtualbox network mode to NAT, and don't use any port forwarding

With addresses other than 0.0.0.0 I had no success.

//x=address or src
if(x.includes('/')==true){xp=x.split('/')} //split address
if(x.includes('\\')==true){xp=x.split('\\')} //split address
xl=xp.length*1-1;xn=xp[xl] //file==xn

seq_along may help to find out how many rows in your data file and create a data.frame with the desired number of rows

    listdf <- data.frame(ID=seq_along(df),
                              var1=seq_along(df), var2=seq_along(df))

Heads up, you might need to restart LAMP, Apache or whatever your using to make this take affect. Racked our brains for a while on this one, seemed to make no affect until services were restarted, presumably because the website was caching.

Make your size a factor in your dataframe by:

temp$size_f = factor(temp$size, levels=c('50%','100%','150%','200%'))

Then change the facet_grid(.~size) to facet_grid(.~size_f)

Then plot:

The graphs are now in the correct order.

For everyone struggling with this issue, you simply need to upgrade your openssl installation. I'm running windows 10, installed the latest anaconda 64-bit and am getting this error when I try to install/upgrade anything with 'conda' or 'pip'. If I uninstall the 64-bit anaconda and install the 32-bit, it works fine. I had a 64-bit version of openssl for windows installed, version 1.1.0 something. I uninstalled that and installed the latest I could find from here: https://slproweb.com/products/Win32OpenSSL.html -- there is a 64-bit version of 1.1.1 on there that worked. Now I can install packages via pip and conda successfully. Hope this helps.

Just add this line

sFileName = "C:\someotherfilelocation"

right before this line

Open sFileName For Output As iFileNum

The idea is to open and write to a different file than the one you read earlier (C:\filelocation).

If you want to get fancy and show a real "Save As" dialog box, you could do this instead:

sFileName = Application.GetSaveAsFilename()

Whether can we declare the same bean id in other xml for other reference e.x.

Servlet-Initialize.xml

<bean id="inheritedTestBean"   class="org.springframework.beans.TestBean">
  <property name="name" value="parent"/>
  <property name="age" value="1"/>
</bean>

Other xml (Document.xml)

<bean id="inheritedTestBean"  class="org.springframework.beans.Document">
  <property name="name" value="document"/>
  <property name="age" value="1"/>
</bean>

In the first situation, Num2 is extending the class Num and since you are not redefining the special method named __init__() in Num2, it gets inherited from Num.

When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance.

In the second situation, since you are redefining __init__() in Num2 you need to explicitly call the one in the super class (Num) if you want to extend its behavior.

class Num2(Num):
    def __init__(self,num):
        Num.__init__(self,num)
        self.n2 = num*2

My version was a combination of accepted and most upvoted answers. But it's a little bit different, because everyone uses SHA1 but nobody tells you how to get it

$ git init
$ git remote add <remote_url>
$ git fetch --all

now you can see all branches & commits

$ git branch -a
$ git log remotes/origin/master <-- or any other branch

Finally you know SHA1 of desired commit

git reset --hard <sha1>

CodeIgniter returns result rows as objects, not arrays. From the user guide:

result()

---

This function returns the query result as an array of objects, or an empty array on failure.

You'll have to access the fields using the following notation:

foreach ($getvidids->result() as $row) {
    $vidid = $row->videoid;
}

My StreamEx library which enhances the Java 8 streams provides a special operation distinct(atLeast) which can retain only elements appearing at least the specified number of times. So your problem can be solved like this:

List<Integer> repeatingNumbers = StreamEx.of(numbers).distinct(2).toList();

Internally it's similar to @Dave solution, it counts objects, to support other wanted quantities and it's parallel-friendly (it uses ConcurrentHashMap for parallelized stream, but HashMap for sequential). For big amounts of data you can get a speed-up using .parallel().distinct(2).

it's well documented here:

https://cwiki.apache.org/confluence/display/TOMCAT/Connectors#Connectors-Q6

How do I bind to a specific ip address? - "Each Connector element allows an address property. See the HTTP Connector docs or the AJP Connector docs". And HTTP Connectors docs:

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html

Standard Implementation -> address

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."

First, I move ramdom5() on the 1 point 6 times, to get 7 random numbers. Second, I add 7 numbers to obtain common sum. Third, I get remainder of the division at 7. Last, I add 1 to get results from 1 till 7. This method gives an equal probability of getting numbers in the range from 1 to 7, with the exception of 1. 1 has a slightly higher probability.

public int random7(){
    Random random = new Random();
    //function (1 + random.nextInt(5)) is given
    int random1_5 = 1 + random.nextInt(5); // 1,2,3,4,5
    int random2_6 = 2 + random.nextInt(5); // 2,3,4,5,6
    int random3_7 = 3 + random.nextInt(5); // 3,4,5,6,7
    int random4_8 = 4 + random.nextInt(5); // 4,5,6,7,8
    int random5_9 = 5 + random.nextInt(5); // 5,6,7,8,9
    int random6_10 = 6 + random.nextInt(5); //6,7,8,9,10
    int random7_11 = 7 + random.nextInt(5); //7,8,9,10,11

    //sumOfRandoms is between 28 and 56
    int sumOfRandoms = random1_5 + random2_6 + random3_7 + 
                       random4_8 + random5_9 + random6_10 + random7_11;
    //result is number between 0 and 6, and
    //equals 0 if sumOfRandoms = 28 or 35 or 42 or 49 or 56 , 5 options
    //equals 1 if sumOfRandoms = 29 or 36 or 43 or 50, 4 options
    //equals 2 if sumOfRandoms = 30 or 37 or 44 or 51, 4 options
    //equals 3 if sumOfRandoms = 31 or 38 or 45 or 52, 4 options
    //equals 4 if sumOfRandoms = 32 or 39 or 46 or 53, 4 options
    //equals 5 if sumOfRandoms = 33 or 40 or 47 or 54, 4 options
    //equals 6 if sumOfRandoms = 34 or 41 or 48 or 55, 4 options
    //It means that the probabilities of getting numbers between 0 and 6 are almost equal.
    int result = sumOfRandoms % 7;
    //we should add 1 to move the interval [0,6] to the interval [1,7]
    return 1 + result;
}

Can you include some code? I add style="display:none;" to my table rows all the time and it effectively hides the entire row.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

If you want to map an object you can use Lodash. Just make sure it's installed via NPM or Yarn and import it.

With Lodash:

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

C# 7.0 introduced Deconstructors and if you are using .NET Core 2.0+ Application, the struct KeyValuePair<> already include a Deconstruct() for you. So you can do:

var dic = new Dictionary<int, string>() { { 1, "One" }, { 2, "Two" }, { 3, "Three" } };
foreach (var (key, value) in dic) {
    Console.WriteLine($"Item [{key}] = {value}");
}
//Or
foreach (var (_, value) in dic) {
    Console.WriteLine($"Item [NO_ID] = {value}");
}
//Or
foreach ((int key, string value) in dic) {
    Console.WriteLine($"Item [{key}] = {value}");
}

I checked out iterrows after noticing Nick Crawford's answer, but found that it yields (index, Series) tuples. Not sure which would work best for you, but I ended up using the itertuples method for my problem, which yields (index, row_value1...) tuples.

There's also iterkv, which iterates through (column, series) tuples.

1. First you need to add all untracked files. Use this command line:

   git add *

2. Then commit using this command line :

   git commit -a

You can also use

border-left: 9vw solid #F5E5D6;
border-right: 9vw solid #F5E5D6;     

OR

border: 9vw solid #F5E5D6;

check this:http://net.tutsplus.com/tutorials/javascript-ajax/quick-tip-quick-and-easy-javascript-testing-with-assert/

it is for testing JavaScript. Amazingly, at barely five or six lines, this code provides a great level of power and control over your code, when testing.

The assert function accepts two parameters:

outcome: A boolean, which references whether your test passed or failed

description: A short description of your test.

The assert function then simply creates a list item, applies a class of either “pass” or “fail,” dependent upon whether your test returned true or false, and then appends the description to the list item. Finally, that block of coded is added to the page. It’s crazy simple, but works perfectly.

I have not seen any option in Microsoft SQL Server Management Studio 2012 to-date that will do that.

I am sure you can write something in T-SQL given the time.

Check out TOAD from QUEST - now owned by DELL.

http://www.toadworld.com/products/toad-for-oracle/f/10/t/9778.aspx

Select your rows.
Rt -click -> Export Dataset.
Choose Insert Statement format
Be sure to check “selected rows only”

Nice thing about toad, it works with both SQL server and Oracle. If you have to work with both, it is a good investment.

you need to call the function like this

$this->assign()

instead of just assign()

Another possibility could be to make use of IN statement:

extensions = ['.mp3','.avi']
file_name  = 'test.mp3'
if "." in file_name and file_name[file_name.rindex("."):] in extensions:
    print(True)

On Windows (with Windows Service).

Edit the file C:\Program Files (x86)\Jenkins\jenkins.xml with 8083 if you want 8083 port.

<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8083</arguments>

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

If I understood you right, you want to copy $var in a file (if it's a string).

echo $var > $destdir

I done in this way

from keras.models import Sequential
from keras_contrib.losses import import crf_loss
from keras_contrib.metrics import crf_viterbi_accuracy

# To save model
model.save('my_model_01.hdf5')

# To load the model
custom_objects={'CRF': CRF,'crf_loss': crf_loss,'crf_viterbi_accuracy':crf_viterbi_accuracy}

# To load a persisted model that uses the CRF layer 
model1 = load_model("/home/abc/my_model_01.hdf5", custom_objects = custom_objects)

In my case it had to do with not having installed previously the GDAL core. For a guide on how to install the GDAL and Basemap libraries go to: https://github.com/felipunky/GISPython/blob/master/README.md

Check for the 32/64 bit you trying to install. both python interpreter and your app which trying to use python might be of different bit.

My images were not getting displayed even after putting them in the correct folder, problem was they did not have the right permission, I changed the permission to read write execute. I used chmod 777 image.png. All worked then, images were getting displayed. :)

Use ==:

pip install django_modeltranslation==0.4.0-beta2

You can try this...

<!--First Solution-->_x000D_
width: calc(100% - 100px);_x000D_
<!--Second Solution-->_x000D_
width: calc(100vh - 100px);

vw: viewport width

vh: viewport height

if you don't like the double brackets or you don't want to write a function, you can just use a variable.

$path = Test-Path C:\Code
if (!$path) {
    write "it doesn't exist!"
}

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)
