Include servlet-api-3.1.jar in your dependencies.

• Maven

  <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
  </dependency>
  

• Gradle

  configurations {
      provided
  }
  sourceSets {
      main { compileClasspath += configurations.provided }
  }
  dependencies {
      provided 'javax.servlet:javax.servlet-api:3.1.0'
  }
  

Have you looked at any of the Maven docs, for example, the maven install plugin docs?

Nutshell version: it will build the project and install it in your local repository.

Right click on project-> Maven->Click checked box 'Force Update'->Update

Change:

<!-- ANT4X -->
<dependency>
  <groupId>net.sourceforge</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

To:

<!-- ANT4X -->
<dependency>
  <groupId>net.sourceforge.ant4x</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

The groupId of net.sourceforge was incorrect. The correct value is net.sourceforge.ant4x.

Oh, and: don't use Java 1.3.x, current versions are Java 1.7.x or 1.8.x

I solved this by looking at this comment on JBIDE-11655 : deleting all .project, .settings and .classpath in my projects folder.

It is not too hard. I have not read the license yet. However I have proven this works. You can copy sqljdbc4 jar file to a network share or local directory. Your build.gradle should look like this :

apply plugin: 'java'
//apply plugin: 'maven'
//apply plugin: 'enhance'

sourceCompatibility = 1.8
version = '1.0'

//library versions
def hibernateVersion='4.3.10.Final'
def microsoftSQLServerJDBCLibVersion='4.0'
def springVersion='2.5.6'

def log4jVersion='1.2.16'
def jbossejbapiVersion='3.0.0.GA'

repositories {
    mavenCentral()
    maven{url "file://Sharedir/releases"}
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
    compile "org.hibernate:hibernate-core:$hibernateVersion"
    compile "com.microsoft.sqlserver:sqljdbc4:$microsoftSQLServerJDBCLibVersion"
}

task showMeCache << {
    configurations.compile.each { println it }
}

under the sharedir/releases directory, I have directory similar to maven structure which is \sharedir\releases\com\microsoft\sqlserver\sqljdbc4\4.0\sqljdbc4-4.0.jar

good luck.

Activation by system properties can be done as follows

<activation>
    <property>
        <name>foo</name>
        <value>bar</value>
    </property>
</activation>

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.

You should include the repository where you want to deploy in the distribution management section of the pom.xml.

Example:

<project xmlns="http://maven.apache.org/POM/4.0.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
...   
<distributionManagement>
    <repository>
      <uniqueVersion>false</uniqueVersion>
      <id>corp1</id>
      <name>Corporate Repository</name>
      <url>scp://repo/maven2</url>
      <layout>default</layout>
    </repository>
    ...
</distributionManagement>
...
</project>

See Distribution Management

You need to check your relative path, based on depth of your modules from parent if module is just below parent then in module put relative path as: ../pom.xml

if its 2 level down then ../../pom.xml

I had this exact problem today and the problem was that the version I was trying to release:perform was already in the Nexus repo.

In my case this was likely due to a network disconnect during an earlier invocation of release:perform. Even though I lost my connection, it appears the release succeeded.

The difference between <pluginManagement/> and <plugins/> is that a <plugin/> under:

• <pluginManagement/> defines the settings for plugins that will be inherited by modules in your build. This is great for cases where you have a parent pom file.

• <plugins/> is a section for the actual invocation of the plugins. It may or may not be inherited from a <pluginManagement/>.

You don't need to have a <pluginManagement/> in your project, if it's not a parent POM. However, if it's a parent pom, then in the child's pom, you need to have a declaration like:

<plugins>
    <plugin>
        <groupId>com.foo</groupId>
        <artifactId>bar-plugin</artifactId>
    </plugin>
</plugins>

Notice how you aren't defining any configuration. You can inherit it from the parent, unless you need to further adjust your invocation as per the child project's needs.

For more specific information, you can check:

• The Maven pom.xml reference: Plugins

• The Maven pom.xml reference: Plugin Management

Add option

-XX:MaxPermSize=512m

to MAVEN_OPTS

maven-compiler-plugin options

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.5.1</version>
    <configuration>
      <fork>true</fork>
      <meminitial>1024m</meminitial>
      <maxmem>2024m</maxmem>
    </configuration>
  </plugin>

As per Where is Maven Installed on Ubuntu it will first create your settings.xml on /usr/share/maven2/, then you can copy to your home folder as jens mentioned

$ cp /usr/share/maven3/conf/settings.xml ~/.m2/settings.xml

Maven uses variable $JAVACMD as the final java command, set it to where the java executable is will switch maven to different JDK.

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

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

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

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

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

In my pom.xml file I had to downgrade the version from 2.1.6.RELEASE for spring-boot-starter-parent artifact to 2.1.4.RELEASE

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
</parent>

to be changed to

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
</parent>

And that weird Unknown error disappeared

It might be safer to directly pass environment variables to maven system properties. For example, say on Linux you want to access environment variable MY_VARIABLE. You can use a system property in your pom file.

<properties>
    ...
    <!-- Default value for my.variable can be defined here -->
    <my.variable>foo</my.variable>
    ...
</properties>
...
<!-- Use my.variable -->
... ${my.variable} ...

Set the property value on the maven command line:

mvn clean package -Dmy.variable=$MY_VARIABLE

I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:

1. Annotation settings are changed for the modules
2. Compiler output path is changed for the modules
3. Resources settings are ignored totally and only taken from pom.xml
4. Module dependencies are messed up and have to checked
5. Language/Encoding settings are changed for the modules

All these points need review and adjusting but after this it works like charm.

Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Edit 2019:

• Added recursive resource scan
• Added directory specification which might be important to avoid confusion of IDEA recarding the content root structure

try this one

    <dependency>
        <groupId>com.hynnet</groupId>
        <artifactId>oracle-driver-ojdbc6</artifactId>
        <version>12.1.0.1</version>

Downgrade your version

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version><change this version></version>

Build and undo the version, Build. 2.1.6.RELEASE to 1.3.3.RELEASE Build Undo 1.3.3 to 2.1.6 Build (in my case problem solved) It helped us.

.pom dependency scope can contain:

• compile - available at Compile-time and Run-time
• provided - available at Compile-time. (this dependency should be provided by outer container like OS...)
• runtime - available at Run-time
• test - test compilation and run time
• system - is similar to provided but exposes <systemPath>path/some.jar</systemPath> to point on .jar
• import - is available from Maven v2.0.9 for <type>pom</type> and it should be replaced by effective dependency from this file <dependencyManagement/>

You need to have the file /root/test/devenv/openstack-rhel/pom.xml

This file need to have the followings elements:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.openstack</groupId>
    <artifactId>openstack-rhel-rpms</artifactId>
    <version>2012.1-SNAPSHOT</version>
    <packaging>pom</packaging>
</project>

Dependency Management allows to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. This is especially useful when you have a set of projects (i.e. more than one) that inherits a common parent.

Another extremely important use case of dependencyManagement is the control of versions of artifacts used in transitive dependencies. This is hard to explain without an example. Luckily, this is illustrated in the documentation.

There are a set of available properties to all Maven projects.

From Introduction to the POM:

project.basedir: The directory that the current project resides in.

This means this points to where your Maven projects resides on your system. It corresponds to the location of the pom.xml file. If your POM is located inside /path/to/project/pom.xml then this property will evaluate to /path/to/project.

Some properties are also inherited from the Super POM, which is the case for project.build.directory. It is the value inside the <project><build><directory> element of the POM. You can get a description of all those values by looking at the Maven model. For project.build.directory, it is:

The directory where all files generated by the build are placed. The default value is target.

This is the directory that will hold every generated file by the build.

Some ideas:

1. Maybe you could simply not inherit from the parent in that case (and declare a dependency on base with the exclusion). Not handy if you have lot of stuff in the parent pom.

2. Another thing to test would be to declare the mail artifact with the version required by ALL-DEPS under the dependencyManagement in the parent pom to force the convergence (although I'm not sure this will solve the scoping problem).

<dependencyManagement>
  <dependencies>
    <dependency>    
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>???</version><!-- put the "right" version here -->
    </dependency>
  </dependencies>
</dependencyManagement>

1. Or you could exclude the mail dependency from log4j if you're not using the features relying on it (and this is what I would do):

<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.15</version>
  <scope>provided</scope>
  <exclusions>
    <exclusion>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
    </exclusion>
    <exclusion>
      <groupId>javax.jms</groupId>
      <artifactId>jms</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jdmk</groupId>
      <artifactId>jmxtools</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jmx</groupId>
      <artifactId>jmxri</artifactId>
    </exclusion>
  </exclusions>
</dependency>

1. Or you could revert to the version 1.2.14 of log4j instead of the heretic 1.2.15 version (why didn't they mark the above dependencies as optional?!).

For me in windows 7 it started to work only after I gave 'Read & execute', 'List folder contents', 'Read' permissions to site folder for both users

• IUSR
• NETWORK SERVICE

You can also push markers into an array. See code example, this works for me:

/*create array:*/
var marker = new Array();

/*Some Coordinates (here simulating somehow json string)*/
var items = [{"lat":"51.000","lon":"13.000"},{"lat":"52.000","lon":"13.010"},{"lat":"52.000","lon":"13.020"}];

/*pushing items into array each by each and then add markers*/
function itemWrap() {
for(i=0;i<items.length;i++){
    var LamMarker = new L.marker([items[i].lat, items[i].lon]);
    marker.push(LamMarker);
    map.addLayer(marker[i]);
    }
}

/*Going through these marker-items again removing them*/
function markerDelAgain() {
for(i=0;i<marker.length;i++) {
    map.removeLayer(marker[i]);
    }  
}

Just noting a different way of questionable usefulness, using os.environ:

import os
python_executable_path = os.environ['_']

e.g.

$ python -c "import os; print(os.environ['_'])"
/usr/bin/python

I just did the same. I did it in helper controller, my code is:

def get_controller_name
  controller_name    
end


def get_action_name
  action_name   
end

These methods will return current contoller and action name. Hope it helps

Wrap your script in the ready function. jsFiddle does that automatically for you.

$(function() {
    $('[id^=\"btnRight\"]').click(function (e) {
        $(this).prev('select').find('option:selected').remove().appendTo('#isselect_code');
    });

    $('[id^=\"btnLeft\"]').click(function (e) {
        $(this).next('select').find('option:selected').remove().appendTo('#canselect_code');
    });
});

This is why you should not use third party tools unless you know what they automate/simplify for you.

See the example:

mkdir test && echo "Something" > test/file

Shell will try to create directory test and then, only if it was successfull will try create file inside it.

So you may interrupt a sequence of steps if one of them failed.

I saw this solution here using regex.

import re
if re.search('mandy', 'Mandy Pande', re.IGNORECASE):
# is True

It works well with accents

In [42]: if re.search("ê","ê", re.IGNORECASE):
....:        print(1)
....:
1

However, it doesn't work with unicode characters case-insensitive. Thank you @Rhymoid for pointing out that as my understanding was that it needs the exact symbol, for the case to be true. The output is as follows:

In [36]: "ß".lower()
Out[36]: 'ß'
In [37]: "ß".upper()
Out[37]: 'SS'
In [38]: "ß".upper().lower()
Out[38]: 'ss'
In [39]: if re.search("ß","ßß", re.IGNORECASE):
....:        print(1)
....:
1
In [40]: if re.search("SS","ßß", re.IGNORECASE):
....:        print(1)
....:
In [41]: if re.search("ß","SS", re.IGNORECASE):
....:        print(1)
....:

in the manifest:

<activity android:name=".activity.MainActivity"
        android:screenOrientation="portrait"
        tools:ignore="LockedOrientationActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

or : in the MainActivity

@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

I think Semaphore is what you are looking for, it will block the main process after counting down to 0. Sample code:

from multiprocessing import Process
from multiprocessing import Semaphore
import time

def f(name, sema):
    print('process {} starting doing business'.format(name))
    # simulate a time-consuming task by sleeping
    time.sleep(5)
    # `release` will add 1 to `sema`, allowing other 
    # processes blocked on it to continue
    sema.release()

if __name__ == '__main__':
    concurrency = 20
    total_task_num = 1000
    sema = Semaphore(concurrency)
    all_processes = []
    for i in range(total_task_num):
        # once 20 processes are running, the following `acquire` call
        # will block the main process since `sema` has been reduced
        # to 0. This loop will continue only after one or more 
        # previously created processes complete.
        sema.acquire()
        p = Process(target=f, args=(i, sema))
        all_processes.append(p)
        p.start()

    # inside main process, wait for all processes to finish
    for p in all_processes:
        p.join()

The following code is more structured since it acquires and releases sema in the same function. However, it will consume too much resources if total_task_num is very large:

from multiprocessing import Process
from multiprocessing import Semaphore
import time

def f(name, sema):
    print('process {} starting doing business'.format(name))
    # `sema` is acquired and released in the same
    # block of code here, making code more readable,
    # but may lead to problem.
    sema.acquire()
    time.sleep(5)
    sema.release()

if __name__ == '__main__':
    concurrency = 20
    total_task_num = 1000
    sema = Semaphore(concurrency)
    all_processes = []
    for i in range(total_task_num):
        p = Process(target=f, args=(i, sema))
        all_processes.append(p)
        # the following line won't block after 20 processes
        # have been created and running, instead it will carry 
        # on until all 1000 processes are created.
        p.start()

    # inside main process, wait for all processes to finish
    for p in all_processes:
        p.join()

The above code will create total_task_num processes but only concurrency processes will be running while other processes are blocked, consuming precious system resources.

Now Jackson supports avoiding cycles without ignoring the fields:

Jackson - serialization of entities with birectional relationships (avoiding cycles)

Method 1: (Scala)

val sqlContext = new org.apache.spark.sql.SQLContext(sc)

For perl,

To run perl script use this procedure

Requirement: You need to setup classpath variable.

Go to plugins->NppExec->Execute

In command section, type this

cmd /c cd "$(CURRENT_DIRECTORY)"&&"$(FULL_CURRENT_PATH)"

Save it and give name to it.(I give Perl).

Press OK. If editor wants to restart, do it first.

Now press F6 and you will find your Perl script output on below side.

Note: Not required seperate config for seperate files.

For java,

That's it!!

in .NET 2.0 (no Linq):

public static List<string> GetFilez(string path, System.IO.SearchOption opt,  params string[] patterns)
{
    List<string> filez = new List<string>();
    foreach (string pattern in patterns)
    {
        filez.AddRange(
            System.IO.Directory.GetFiles(path, pattern, opt)
        );
    }


    // filez.Sort(); // Optional
    return filez; // Optional: .ToArray()
}

Then use it:

foreach (string fn in GetFilez(path
                             , System.IO.SearchOption.AllDirectories
                             , "*.xml", "*.xml.rels", "*.rels"))
{}

As far as I can see, all other answers so far used a collector to add elements to an existing stream. However, there's a shorter solution, and it works for both sequential and parallel streams. You can simply use the method forEachOrdered in combination with a method reference.

List<String> source = ...;
List<Integer> target = ...;

source.stream()
      .map(String::length)
      .forEachOrdered(target::add);

The only restriction is, that source and target are different lists, because you are not allowed to make changes to the source of a stream as long as it is processed.

Note that this solution works for both sequential and parallel streams. However, it does not benefit from concurrency. The method reference passed to forEachOrdered will always be executed sequentially.

The size_t type is the unsigned integer type that is the result of the sizeof operator (and the offsetof operator), so it is guaranteed to be big enough to contain the size of the biggest object your system can handle (e.g., a static array of 8Gb).

The size_t type may be bigger than, equal to, or smaller than an unsigned int, and your compiler might make assumptions about it for optimization.

You may find more precise information in the C99 standard, section 7.17, a draft of which is available on the Internet in pdf format, or in the C11 standard, section 7.19, also available as a pdf draft.

I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:

HKEY_LOCAL_MACHINE\SOFTWARE\Python

to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python

Worked for me

You can specify the cookie file with a curl opt. You could use a unique file for each user.

curl_setopt( $curl_handle, CURLOPT_COOKIESESSION, true );
curl_setopt( $curl_handle, CURLOPT_COOKIEJAR, uniquefilename );
curl_setopt( $curl_handle, CURLOPT_COOKIEFILE, uniquefilename );

The best way to handle it would be to stick your request logic into a curl function and just pass the unique file name in as a parameter.

    function fetch( $url, $z=null ) {
            $ch =  curl_init();

            $useragent = isset($z['useragent']) ? $z['useragent'] : 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2';

            curl_setopt( $ch, CURLOPT_URL, $url );
            curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
            curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
            curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
            curl_setopt( $ch, CURLOPT_POST, isset($z['post']) );

            if( isset($z['post']) )         curl_setopt( $ch, CURLOPT_POSTFIELDS, $z['post'] );
            if( isset($z['refer']) )        curl_setopt( $ch, CURLOPT_REFERER, $z['refer'] );

            curl_setopt( $ch, CURLOPT_USERAGENT, $useragent );
            curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, ( isset($z['timeout']) ? $z['timeout'] : 5 ) );
            curl_setopt( $ch, CURLOPT_COOKIEJAR,  $z['cookiefile'] );
            curl_setopt( $ch, CURLOPT_COOKIEFILE, $z['cookiefile'] );

            $result = curl_exec( $ch );
            curl_close( $ch );
            return $result;
    }

I use this for quick grabs. It takes the url and an array of options.

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

In general, static means "associated with the type itself, rather than an instance of the type."

That means you can reference a static variable without having ever created an instances of the type, and any code referring to the variable is referring to the exact same data. Compare this with an instance variable: in that case, there's one independent version of the variable per instance of the class. So for example:

Test x = new Test();
Test y = new Test();
x.instanceVariable = 10;
y.instanceVariable = 20;
System.out.println(x.instanceVariable);

prints out 10: y.instanceVariable and x.instanceVariable are separate, because x and y refer to different objects.

You can refer to static members via references, although it's a bad idea to do so. If we did:

Test x = new Test();
Test y = new Test();
x.staticVariable = 10;
y.staticVariable = 20;
System.out.println(x.staticVariable);

then that would print out 20 - there's only one variable, not one per instance. It would have been clearer to write this as:

Test x = new Test();
Test y = new Test();
Test.staticVariable = 10;
Test.staticVariable = 20;
System.out.println(Test.staticVariable);

That makes the behaviour much more obvious. Modern IDEs will usually suggest changing the second listing into the third.

There is no reason to have an inline declaration initializing the value like the following, as each instance will have its own NUMBER but always with the same value (is immutable and initialized with a literal). This is the same than to have only one final static variable for all instances.

private final int NUMBER = 10;

Therefore if it cannot change, there is no point having one copy per instance.

But, it makes sense if is initialized in a constructor like this:

// No initialization when is declared
private final int number;

public MyClass(int n) {
   // The variable can be assigned in the constructor, but then
   // not modified later.
   number = n;
}

Now, for each instance of MyClass, we can have a different but immutable value of number.

Try this code. By using the parent>child selector "#productList li" it should find all li elements. Then, you can iterate through the result object using the each() method which will only alter li elements that have been found.

listItems = $("#productList li").each(function(){

        var product = $(this);
        var productid = product.children(".productId").val();
        var productPrice = product.find(".productPrice").val();
        var productMSRP = product.find(".productMSRP").val();

        totalItemsHidden.val(parseInt(totalItemsHidden.val(), 10) + 1);
        subtotalHidden.val(parseFloat(subtotalHidden.val()) + parseFloat(productMSRP));
        savingsHidden.val(parseFloat(savingsHidden.val()) + parseFloat(productMSRP - productPrice));
        totalHidden.val(parseFloat(totalHidden.val()) + parseFloat(productPrice));

    });

SELECT DATEDIFF(day,'2014-06-05','2014-08-05') AS DiffDate

If you are using an <img> tag for the SVG, then you cannot manipulate its contents (as far as I know).

As the accepted answer shows, using <object> is an option.

I needed this recently and used gulp-inject during my gulp build to inject the contents of an SVG file directly into the HTML document as an <svg> element, which is then very easy to work with using CSS selectors and querySelector/getElementBy*.

You've tried alot. And I feel for you. Here is an idea. I kinda followed everything you tried. The mental note I have in my head goes like this: "When Sql Server won't connect when you've tried everything, wire up your firewall rules by the program, not the port"

I know you said you disabled the firewall. But something is telling me to give this a try anyways.

I think you have to open the firewall "by program", and not by port.

http://technet.microsoft.com/en-us/library/cc646023.aspx

To add a program exception to the firewall using the Windows Firewall item in Control Panel.


On the Exceptions tab of the Windows Firewall item in Control Panel, click Add a program.


Browse to the location of the instance of SQL Server that you want to allow through the firewall, for example C:\Program Files\Microsoft SQL Server\MSSQL11.<instance_name>\MSSQL\Binn, select sqlservr.exe, and then click Open.


 Click OK.

EDIT..........

I'm a little cloudy on which "program" you're trying to use on SQLB?

Is it SSMS on SQLB? Or a client program on SQLB ?

EDIT...........

No idea if this will help. But I use this to ping "ports" ... and something that is outside of the SSMS world.

I was trying to run .jar from C# code using Process class. The java code ran successfully from eclipse but it doesn't from C# visual studio and even clicking directly on the jar file, it always stopped with ClassNotFoundException: exception. Solution for my, was export the java program as "Runnable JAR file" instead of "JAR File". Hope it can help someone.

tl;dr

• "Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.

• Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).

• Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.

• Also, it seems likely the military FUBAR contributed to their popularity.

The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)

OK, so let's find some references.

STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:

On Foo-ism

The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")

As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.

It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!

The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:

By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.

...

It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.

Hopefully yours,

Indignant Mother of Five.

And The Tech in December 1938:

General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."

The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:

FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.

These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:

Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.

And from 1996's Jargon File 4.0.0:

Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):

Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!

Also 1964's MIT Voo Doo (PDF) references the TMRC usage:

Yes! I want to be an instant success and snow customers. Send me a degree in: ...

• Foo Counters

• Foo Jung

Let's find "foo", "bar" and "foobar" published in code examples.

So, Jargon File 4.4.7 says of "foobar":

Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.

The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:

Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.

Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z

I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:

car[((FOO . CROCK) . GLITCH)]

It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER

For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:

EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).

Some more recallations.

@Walter Mitty recalled on this site in 2008:

I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.

John V. Everett recalls in 1996:

When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.

It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.

Daniel P. B. Smith in 1998:

Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.

Robert Schuldenfrei in 1996:

The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?

Paul M. Wexelblat in 1992:

The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.

Bruce B. Reynolds in 1996:

On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...

Here's a straight IBM "BAR" from 1955.

Other early references:

• 1967 foo bar MIT AIM-127

• 1967 foo bar MIT AIM-127a

• 1965 foo MIT Tech Engineering News

I haven't been able to find any references to foo bar as "inverted foo signal" as suggested in RFC3092 and elsewhere.

Here are a some of even earlier F00s but I think they're coincidences/false positives:

• 1959 "FOO 31 IBM-704 Bettis Plant Uses a least squares technique" U.S. Atomic Energy Commission

• 1960 FOO (FO Out, F1, F2, FOO, FOI) "Digital computer and control engineering"

Note: the hash is important!

You could use replicate or sapply:

R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL))) 

replicate is a wrapper for the common use of sapply for repeated evaluation of an expression (which will usually involve random number generation).

First up let me start by saying why we need a database.

We need a database to help organise information in such a manner that we can retrieve that data stored in a efficient manner.

Examples of relational database management systems(SQL):

1)Oracle Database

2)SQLite

3)PostgreSQL

4)MySQL

5)Microsoft SQL Server

6)IBM DB2

Examples of non relational database management systems(NoSQL)

1)MongoDB

2)Cassandra

3)Redis

4)Couchbase

5)HBase

6)DocumentDB

7)Neo4j

Relational databases have normalized data, as in information is stored in tables in forms of rows and columns, and normally when data is in normalized form, it helps to reduce data redundancy, and the data in tables are normally related to each other, so when we want to retrieve the data, we can query the data by using join statements and retrieve data as per our need.This is suited when we want to have more writes, less reads, and not much data involved, also its really easy relatively to update data in tables than in non relational databases. Horizontal scaling not possible, vertical scaling possible to some extent.CAP(Consistency, Availability, Partition Tolerant), and ACID (Atomicity, Consistency, Isolation, Duration)compliance.

Let me show entering data to a relational database using PostgreSQL as an example.

First create a product table as follows:

CREATE TABLE products (
    product_no integer,
    name text,
    price numeric
);

then insert the data

INSERT INTO products (product_no, name, price) VALUES (1, 'Cheese', 9.99);

Let's look at another different example:

Here in a relational database, we can link the student table and subject table using relationships, via foreign key, subject ID, but in a non relational database no need to have two documents, as no relationships, so we store all the subject details and student details in one document say student document, then data is getting duplicated, which makes updating records troublesome.

In non relational databases, there is no fixed schema, data is not normalized. no relationships between data is created, all data mostly put in one document. Well suited when handling lots of data, and can transfer lots of data at once, best where high amounts of reads and less writes, and less updates, bit difficult to query data, as no fixed schema. Horizontal and vertical scaling is possible.CAP (Consistency, Availability, Partition Tolerant)and BASE (Basically Available, soft state, Eventually consistent)compliance.

Let me show an example to enter data to a non relational database using Mongodb

db.users.insertOne({name: ‘Mary’, age: 28 , occupation: ‘writer’ })
db.users.insertOne({name: ‘Ben’ , age: 21})

Hence you can understand that to the database called db, and there is a collections called users, and document called insertOne to which we add data, and there is no fixed schema as our first record has 3 attributes, and second attribute has 2 attributes only, this is no problem in non relational databases, but this cannot be done in relational databases, as relational databases have a fixed schema.

Let's look at another different example

({Studname: ‘Ash’, Subname: ‘Mathematics’, LecturerName: ‘Mr. Oak’})

Hence we can see in non relational database we can enter both student details and subject details into one document, as no relationships defined in non relational databases, but here this way can lead to data duplication, and hence errors in updating can occur therefore.

Hope this explains everything

You probably are looking for find_in_set function:

Where find_in_set($needle,'column') > 0

This function acts like in_array function in PHP

The problem was solved by reinstalling Visual Studio 2015.

This should get you started:

set datafile separator ","
plot 'infile' using 0:1

In the case of a vector and list, the main differences that stick out to me are the following:

vector

• A vector stores its elements in contiguous memory. Therefore, random access is possible inside a vector which means that accessing an element of a vector is very fast because we can simply multiply the base address with the item index to access that element. In fact, it takes only O(1) or constant time for this purpose.

• Since a vector basically wraps an array, every time you insert an element into the vector (dynamic array), it has to resize itself by finding a new contiguous block of memory to accommodate the new elements which is time-costly.

• It does not consume extra memory to store any pointers to other elements within it.

list

• A list stores its elements in non-contiguous memory. Therefore, random access is not possible inside a list which means that to access its elements we have to use the pointers and traverse the list which is slower relative to vector. This takes O(n) or linear time which is slower than O(1).

• Since a list uses non-contiguous memory, the time taken to insert an element inside a list is a lot more efficient than in the case of its vector counterpart because reallocation of memory is avoided.

• It consumes extra memory to store pointers to the element before and after a particular element.

So, keeping these differences in mind, we usually consider memory, frequent random access and insertion to decide the winner of vector vs list in a given scenario.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

perl -e 'map { $on=$_; s/ /_/; rename($on, $_) or warn $!; } <*>;'

Match et replace space > underscore of all files in current directory

Based on First answer here is the complete image selection options:

Filter = @"|All Image Files|*.BMP;*.bmp;*.JPG;*.JPEG*.jpg;*.jpeg;*.PNG;*.png;*.GIF;*.gif;*.tif;*.tiff;*.ico;*.ICO
           |PNG|*.PNG;*.png
           |JPEG|*.JPG;*.JPEG*.jpg;*.jpeg
           |Bitmap(.BMP,.bmp)|*.BMP;*.bmp                                    
           |GIF|*.GIF;*.gif
           |TIF|*.tif;*.tiff
           |ICO|*.ico;*.ICO";

argv[1] is a pointer to a string.

You can print the string it points to using printf("%s\n", argv[1]);

To get an integer from a string you have first to convert it. Use strtol to convert a string to an int.

#include <errno.h>   // for errno
#include <limits.h>  // for INT_MAX
#include <stdlib.h>  // for strtol
 
char *p;
int num;

errno = 0;
long conv = strtol(argv[1], &p, 10);

// Check for errors: e.g., the string does not represent an integer
// or the integer is larger than int
if (errno != 0 || *p != '\0' || conv > INT_MAX) {
    // Put here the handling of the error, like exiting the program with
    // an error message
} else {
    // No error
    num = conv;    
    printf("%d\n", num);
}

May be use like this

if($match > 0){
 $msg = 'Login Complete! Thanks';
 echo "<a href='".$link_address."'>link</a>";
 }
else{
 $msg = 'Login Failed!<br /> Please make sure that you enter the correct  details and that you have activated your account.';
}

If you pass an Exception class to assertRaises(), a context manager is provided. This can improve the readability of your tests:

# raise exception if Application created with bad data
with self.assertRaises(pySourceAidExceptions.PathIsNotAValidOne):
    application = Application("abcdef", "")

This allows you to test error cases in your code.

In this case, you are testing the PathIsNotAValidOne is raised when you pass invalid parameters to the Application constructor.

<script>
function check(){
    return false;
}
 </script>

<form name="form1" method="post" onsubmit="return check();" action="target">
<input type="text" />
<input type="submit" value="enviar" />

</form>

You can use phpseclib pollyfill package. You can not use open ssl or libsodium for encrypt/decrypt with rijndael 256. Another issue, you don't need replacement any code.

CSS:

.focus {
    border-color:red;
}

JQuery:

  $(document).ready(function() {

    $('input').blur(function() {
        $('input').removeClass("focus");
      })
      .focus(function() {
        $(this).addClass("focus")
      });
  });

For complex splitting you could use a regex creating a match collection.

Try this, it must be work, otherwise you need to print the error to specify your problem

$username = $_POST['username'];
$password = $_POST['password'];

$sql = "SELECT * from Users WHERE UserName LIKE '$username'";
$result = mysql_query($sql,$con);

while($row = mysql_fetch_array($result))
{
    echo $row['FirstName'];
}

You can use strstr. Example code here.

Note that the returned result is not null terminated.

Check if the scrollable element is already scrolled to the top when trying to scroll up or to the bottom when trying to scroll down and then preventing the default action to stop the entire page from moving.

var touchStartEvent;
$('.scrollable').on({
    touchstart: function(e) {
        touchStartEvent = e;
    },
    touchmove: function(e) {
        if ((e.originalEvent.pageY > touchStartEvent.originalEvent.pageY && this.scrollTop == 0) ||
            (e.originalEvent.pageY < touchStartEvent.originalEvent.pageY && this.scrollTop + this.offsetHeight >= this.scrollHeight))
            e.preventDefault();
    }
});

Create 2 methods which handle the cases. You can instruct the @RequestMapping annotation to take into account certain parameters whilst mapping the request. That way you can nicely split this into 2 methods.

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"logout"})
public String handleLogout(@PathVariable("id") String id, 
        @RequestParam("logout") String logout) { ... }

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"name", "password"})
public String handleLogin(@PathVariable("id") String id, @RequestParam("name") 
        String username, @RequestParam("password") String password, 
        @ModelAttribute("submitModel") SubmitModel model, BindingResult errors) 
        throws LoginException {...}

This is a prompt to create a bunch of object, such as sp_help_diagram (?), that do not exist.

This should have nothing to do with the owner of the db.

Note: This will completely remove nodejs from your system; then you can make a fresh install from the below commands.

Removing Nodejs and Npm

sudo apt-get remove nodejs npm node
sudo apt-get purge nodejs

Now remove .node and .npm folders from your system

sudo rm -rf /usr/local/bin/npm 
sudo rm -rf /usr/local/share/man/man1/node* 
sudo rm -rf /usr/local/lib/dtrace/node.d 
sudo rm -rf ~/.npm 
sudo rm -rf ~/.node-gyp 
sudo rm -rf /opt/local/bin/node 
sudo rm -rf opt/local/include/node 
sudo rm -rf /opt/local/lib/node_modules  

sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*

Go to home directory and remove any node or node_modules directory, if exists.

You can verify your uninstallation by these commands; they should not output anything.

which node
which nodejs
which npm

Installing NVM (Node Version Manager) by downloading and running a script

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

The command above will clone the NVM repository from Github to the ~/.nvm directory:

Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

As the output above says, you should either close and reopen the terminal or run the commands to add the path to nvm script to the current shell session. You can do whatever is easier for you.

Once the script is in your PATH, verify that nvm was properly installed by typing:

nvm --version

which should give this output:

0.34.0

Installing Node.js and npm

nvm install node
nvm install --lts

Once the installation is completed, verify it by printing the Node.js version:

node --version

should give this output:

v12.8.1

Npm should also be installed with node, verify it using

npm -v

should give:

6.13.4

Extra - [Optional] You can also use two different versions of node using nvm easily

nvm install 8.10.0 # just put the node version number Now switch between node versions

$ nvm ls
->     v12.14.1
        v13.7.0
default -> lts/* (-> v12.14.1)
node -> stable (-> v13.7.0) (default)
stable -> 13.7 (-> v13.7.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.14.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.18.1 (-> N/A)

In my case v12.14.1 and v13.7.0 both are installed, to switch I have to just use

nvm use 12.14.1

Configuring npm for global installations In your home directory, create a directory for global installations:

mkdir ~/.npm-global

Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

In your preferred text editor, open or create a ~/.profile file if does not exist and add this line:

PATH="$HOME/.npm-global/bin:$PATH"

On the command line, update your system variables:

source ~/.profile

That's all

str="1w 2d 1h"
regex="([0-9])w ([0-9])d ([0-9])h"
if [[ $str =~ $regex ]]
then
    week="${BASH_REMATCH[1]}"
    day="${BASH_REMATCH[2]}"
    hour="${BASH_REMATCH[3]}"
    echo $week --- $day ---- $hour
fi

output: 1 --- 2 ---- 1

For encoding/decoding numbers to/from byte sequences, there's the encoding/binary package. There are examples in the documentation: see the Examples section in the table of contents.

These encoding functions operate on io.Writer interfaces. The net.TCPConn type implements io.Writer, so you can write/read directly to network connections.

If you've got a Go program on either side of the connection, you may want to look at using encoding/gob. See the article "Gobs of data" for a walkthrough of using gob (skip to the bottom to see a self-contained example).

I wanted my XAML to remain as elegant as possible so I created a class to wrap the bool which resides in one of my shared libraries, the implicit operators allow the class to be used as a bool in code-behind seamlessly

public class InvertableBool
{
    private bool value = false;

    public bool Value { get { return value; } }
    public bool Invert { get { return !value; } }

    public InvertableBool(bool b)
    {
        value = b;
    }

    public static implicit operator InvertableBool(bool b)
    {
        return new InvertableBool(b);
    }

    public static implicit operator bool(InvertableBool b)
    {
        return b.value;
    }

}

The only changes needed to your project are to make the property you want to invert return this instead of bool

    public InvertableBool IsActive 
    { 
        get 
        { 
            return true; 
        } 
    }

And in the XAML postfix the binding with either Value or Invert

IsEnabled="{Binding IsActive.Value}"

IsEnabled="{Binding IsActive.Invert}"

I create a file dif.go that contains your code:

package dif

import (
    "time"
)

var StartTime = time.Now()

Outside the folder I create my main.go, it is ok!

package main

import (
    dif "./dif"
    "fmt"
)

func main() {
    fmt.Println(dif.StartTime)
}

Outputs:

2016-01-27 21:56:47.729019925 +0800 CST

Files directory structure:

folder
  main.go
  dif
    dif.go

It works!

You can use

x = [1, 2, 3]
disp(sprintf('Answer: (%d, %d, %d)', x))

This results in

Answer: (1, 2, 3)

For vectors of arbitrary size, you can use

disp(strrep(['Answer: (' sprintf(' %d,', x) ')'], ',)', ')'))

An alternative way would be

disp(strrep(['Answer: (' num2str(x, ' %d,') ')'], ',)', ')'))

We can find the the mean of a row using the range function, i.e in your case, from the Y1961 column to the Y1965

df['mean'] = df.iloc[:, 0:4].mean(axis=1)

And if you want to select individual columns

df['mean'] = df.iloc[:, [0,1,2,3,4].mean(axis=1)

The KeyPress event is not raised by noncharacter keys; however, the noncharacter keys do raise the KeyDown and KeyUp events.

If you are working on the mongo shell, Please refer this : Answer from Tyler Brock

I wrote the answer if you are using mongodb using node.js

You don't need to convert the id into an ObjectId. Just use :

db.collection.findById('4ecbe7f9e8c1c9092c000027');

this collection method will automatically convert id into ObjectId.

On the other hand :

db.collection.findOne({"_id":'4ecbe7f9e8c1c9092c000027'}) doesn't work as expected. You've manually convert id into ObjectId.

That can be done like this :

let id = '58c85d1b7932a14c7a0a320d';

let o_id = new ObjectId(id);   // id as a string is passed

db.collection.findOne({"_id":o_id});

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

You can use the https://graph.facebook.com/v3.0/{Place_your_Page_ID here}/feed?fields=id,shares,share_count&access_token={Place_your_access_token_here} to get the shares count.

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

I agree with @Matthew, it will cost a lot if you perform such query.

[ADVICE FOR DEVELOPERS BEFORE STARTING THEIR PROJECTS]

Since we have foreseen this situation at the beginning, we can actually make a collection namely counters with a document to store all the counters in a field with type number.

For example:

For each CRUD operation on the collection, update the counter document:

1. When you create a new collection/subcollection: (+1 in the counter) [1 write operation]
2. When you delete a collection/subcollection: (-1 in the counter) [1 write operation]
3. When you update an existing collection/subcollection, do nothing on the counter document: (0)
4. When you read an existing collection/subcollection, do nothing on the counter document: (0)

Next time, when you want to get the number of collection, you just need to query/point to the document field. [1 read operation]

In addition, you can store the collections name in an array, but this will be tricky, the condition of array in firebase is shown as below:

// we send this
['a', 'b', 'c', 'd', 'e']
// Firebase stores this
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e'}

// since the keys are numeric and sequential,
// if we query the data, we get this
['a', 'b', 'c', 'd', 'e']

// however, if we then delete a, b, and d,
// they are no longer mostly sequential, so
// we do not get back an array
{2: 'c', 4: 'e'}

So, if you are not going to delete the collection , you can actually use array to store list of collections name instead of querying all the collection every time.

Hope it helps!

Updated with Swift 5 Generally we use three type of Local Notifications

1. Simple Local Notification
2. Local Notification with Action
3. Local Notification with Content

Where you can send simple text notification or with action button and attachment.

Using UserNotifications package in your app, the following example Request for notification permission, prepare and send notification as per user action AppDelegate itself, and use view controller listing different type of local notification test.

AppDelegate

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    let notificationCenter = UNUserNotificationCenter.current()
    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        //Confirm Delegete and request for permission
        notificationCenter.delegate = self
        let options: UNAuthorizationOptions = [.alert, .sound, .badge]
        notificationCenter.requestAuthorization(options: options) {
            (didAllow, error) in
            if !didAllow {
                print("User has declined notifications")
            }
        }

        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {
    }
    func applicationDidEnterBackground(_ application: UIApplication) {

Here's a comprehensive yet non-exhaustive list of examples of list operations and whether or not they are thread safe. Hoping to get an answer regarding the obj in a_list language construct here.

Have a look at the python documentation for filter(function, iterable) (from here):

Construct an iterator from those elements of iterable for which function returns true.

So in order to get a list back you have to use list class:

shesaid = list(filter(greetings(), ["hello", "goodbye"]))

But this probably isn't what you wanted, because it tries to call the result of greetings(), which is "hello", on the values of your input list, and this won't work. Here also the iterator type comes into play, because the results aren't generated until you use them (for example by calling list() on it). So at first you won't get an error, but when you try to do something with shesaid it will stop working:

>>> print(list(shesaid))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object is not callable

If you want to check which elements in your list are equal to "hello" you have to use something like this:

shesaid = list(filter(lambda x: x == "hello", ["hello", "goodbye"]))

(I put your function into a lambda, see Randy C's answer for a "normal" function)

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

Firefox stores that number in this setting (you find it in about:config): network.http.max-connections-per-server

For the max connections, Firefox stores that in this setting: network.http.max-connections

import webbrowser  
webbrowser.open(url, new=0, autoraise=True)

Display url using the default browser. If new is 0, the url is opened in the same browser window if possible. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page (“tab”) is opened if possible. If autoraise is True, the window is raised

webbrowser.open_new(url)

Open url in a new window of the default browser

webbrowser.open_new_tab(url)

Open url in a new page (“tab”) of the default browser

You should install a editor (or IDE) supporting Python syntax. It can highlight source code and make basic format checking. For example: Eric4, Spyder, Ninjia, or Emacs, Vi.

1- you need to close the block of the function with '}', which is missing.

2- the argument of querySelector may not be an empty string '' or ' '... Use '*' for all.

3- those arguments will return the needed value:

querySelector('*')

querySelector('input')

querySelector('input[name="pwd"]')

Abstraction is about identifying commonalities and reducing features that you have to work with at different levels of your code.

e.g. I may have a Vehicle class. A Car would derive from a Vehicle, as would a Motorbike. I can ask each Vehicle for the number of wheels, passengers etc. and that info has been abstracted and identified as common from Cars and Motorbikes.

In my code I can often just deal with Vehicles via common methods go(), stop() etc. When I add a new Vehicle type later (e.g. Scooter) the majority of my code would remain oblivious to this fact, and the implementation of Scooter alone worries about Scooter particularities.

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Well, local storage speed greatly depends on the browser the client is using, as well as the operating system. Chrome or Safari on a mac could be much faster than Firefox on a PC, especially with newer APIs. As always though, testing is your friend (I could not find any benchmarks).

I really don't see a huge difference in cookie vs local storage. Also, you should be more worried about compatibility issues: not all browsers have even begun to support the new HTML5 APIs, so cookies would be your best bet for speed and compatibility.

Andrezj's pretty much got it nailed... but here's an easy cross-browser solution.

Take a form like this:

<form>
    <input/>
    <button type="submit" value="some non-default action"/>
    <button type="submit" value="another non-default action"/>
    <button type="submit" value="yet another non-default action"/>

    <button type="submit" value="default action"/>
</form>

and refactor to this:

<form>
    <input/>

    <button style="overflow: visible !important; height: 0 !important; width: 0 !important; margin: 0 !important; border: 0 !important; padding: 0 !important; display: block !important;" type="submit" value="default action"/>

    <button type="submit" value="some non-default action"/>
    <button type="submit" value="another non-default action"/>
    <button type="submit" value="yet another non-default action"/>
    <button type="submit" value="still another non-default action"/>

    <button type="submit" value="default action"/>
</form>

Since the W3C spec indicates multiple submit buttons are valid, but omits guidance as to how the user-agent should handle them, the browser manufacturers are left to implement as they see fit. I've found they'll either submit the first submit button in the form, or submit the next submit button after the form field that currently has focus.

Unfortunately, simply adding a style of display: none; won't work because the W3C spec indicates any hidden element should be excluded from user interactions. So hide it in plain sight instead!

Above is an example of the solution I ended up putting into production. Hitting the enter key triggers the default form submission is behavior as expected, even when other non-default values are present and precede the default submit button in the DOM. Bonus for mouse/keyboard interaction with explicit user inputs while avoiding javascript handlers.

Note: tabbing through the form will not display focus for any visual element yet will still cause the invisible button to be selected. To avoid this issue, simply set tabindex attributes accordingly and omit a tabindex attribute on the invisible submit button. While it may seem out of place to promote these styles to !important, they should prevent any framework or existing button styles from interfering with this fix. Also, those inline styles are definitely poor form, but we're proving concepts here... not writing production code.

Using Document Body:

<body ononline="onlineConditions()" onoffline="offlineConditions()">(...)</body>

Using Javascript Event:

window.addEventListener('load', function() {

  function updateOnlineStatus() {

    var condition = navigator.onLine ? "online" : "offline";
    if( condition == 'online' ){
        console.log( 'condition: online')
    }else{
        console.log( 'condition: offline')
    }

  }

  window.addEventListener('online',  updateOnlineStatus );
  window.addEventListener('offline', updateOnlineStatus );

});

Reference:
Document-Body: ononline Event
Javascript-Event: Online and offline events

Additional Thoughts:
To ship around the "network connection is not the same as internet connection" Problem from the above methods: You can check the internet connection once with ajax on the application start and configure an online/offline mode. Create a reconnect button for the user to go online. And add on each failed ajax request a function that kick the user back into the offline mode.

Just change the class container to container-fullwidth like this :

<div class="container-fullwidth">

from itertools import cycle, islice
def srepeat(string, n):
   return ''.join(islice(cycle(string), n))

The TextBoxFor is a newer MVC input extension introduced in MVC2.

The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

See this page.

If it helps anyone, I tried everything above (https w/token mode) - and still nothing was working. I got no errors, but nothing would be installed in node_modules or package_lock.json. If I changed the token or any letter in the repo name or user name, etc. - I'd get an error. So I knew I had the right token and repo name.

I finally realized it's because the name of the dependency I had in my package.json didn't match the name in the package.json of the repo I was trying to pull. Even npm install --verbose doesn't say there's any problem. It just seems to ignore the dependency w/o error.

If you know that your strings are mostly ASCII you could convert them to UTF-8.

byte[] bytes = string.getBytes("UTF-8");

This may reduce the memory size by about 50%. However, you will get a byte array out and not a string. If you are writing it to a file though, that should not be a problem.

To convert back to a String:

private final Charset UTF8_CHARSET = Charset.forName("UTF-8");
...
String s = new String(bytes, UTF8_CHARSET);

keytool -import -v -alias cacerts -keystore cacerts.jks -storepass changeit -file C:\cacerts.cer

What's about Java code wrapped by a procedure? Simple and works fine.

CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED SNOOZE AS
public final class Snooze {
  private Snooze() {
  }
  public static void snooze(Long milliseconds) throws InterruptedException {
      Thread.sleep(milliseconds);
  }
}

CREATE OR REPLACE PROCEDURE SNOOZE(p_Milliseconds IN NUMBER) AS
    LANGUAGE JAVA NAME 'Snooze.snooze(java.lang.Long)';

1. You can use an enum type in Java 5 and onwards for the purpose you have described. It is type safe.
2. A is an instance variable. (If it has the static modifier, then it becomes a static variable.) Constants just means the value doesn't change.
3. Instance variables are data members belonging to the object and not the class. Instance variable = Instance field.

If you are talking about the difference between instance variable and class variable, instance variable exist per object created. While class variable has only one copy per class loader regardless of the number of objects created.

Java 5 and up enum type

public enum Color{
 RED("Red"), GREEN("Green");

 private Color(String color){
    this.color = color;
  }

  private String color;

  public String getColor(){
    return this.color;
  }

  public String toString(){
    return this.color;
  }
}

If you wish to change the value of the enum you have created, provide a mutator method.

public enum Color{
 RED("Red"), GREEN("Green");

 private Color(String color){
    this.color = color;
  }

  private String color;

  public String getColor(){
    return this.color;
  }

  public void setColor(String color){
    this.color = color;
  }

  public String toString(){
    return this.color;
  }
}

Example of accessing:

public static void main(String args[]){
  System.out.println(Color.RED.getColor());

  // or

  System.out.println(Color.GREEN);
}

If you want to send emails simultaneously to all the admins, you can do something like this:

In your .env file add all the emails as comma separated values:

[email protected],[email protected],[email protected]

so when you going to send the email just do this (yes! the 'to' method of message builder instance accepts an array):

So,

$to = explode(',', env('ADMIN_EMAILS'));

and...

$message->to($to);

will now send the mail to all the admins.

The drop-down is platform-level element, you can't apply CSS to it.

You can overlay an image on top of it using CSS, and call the click event in the element beneath.

Your question is about the operator precedences in mysql and Alex has shown you how to "override" the precedence with parentheses.

But on a side note, if your column date is of the type Date you can use MySQL's date and time functions to fetch the records of the last seven days, like e.g.

SELECT
  *
FROM
  Drinks
WHERE
  email='$Email'
  AND date >= Now()-Interval 7 day

(or maybe Curdate() instead of Now())

Top tip for new SVN users; this may help a little with getting the correct URLs quickly.

Run svn info to display useful information about the current checked-out branch.

The URL should (if you run svn in the root folder) give you the URL you need to copy from.

Also to switch to the newly created branch, use the svn switch command:

svn switch http://my.repo.url/myrepo/branches/newBranchName

You can get with node.getScene, if you don't call from Platform.runLater, the result is a null value.

example null value:

node.getScene();

example no null value:

Platform.runLater(() -> {
    node.getScene().addEventFilter(KeyEvent.KEY_PRESSED, event -> {
               //your event
     });
});

have you tried eager loading?

@attachments = Job.includes(:attachments).find(1).attachments

It is all about preventing definitions from clashing with other code linked in to your project. It means you can keep things separate.

For example you can have one method called "run" in your code and you will still be able to call your method rather than the "run" method that has been defined in some other library that you have linked in.

It allocates space on the heap equal to an integer array of size N, and returns a pointer to it, which is assigned to int* type pointer called "array"

One-liner: re.match(r"pattern", string) # No need to compile

import re
>>> if re.match(r"hello[0-9]+", 'hello1'):
...     print('Yes')
... 
Yes

You can evalute it as bool if needed

>>> bool(re.match(r"hello[0-9]+", 'hello1'))
True

This is probably slower than what you want, but you can do:

>>> tostring = vectorize(lambda x: str(x))
>>> numpy.where(tostring(phis).astype('float64') != phis)
(array([], dtype=int64),)

It looks like it rounds off the values when it converts to str from float64, but this way you can customize the conversion however you like.

Prefixing the string with an @ indicates that it should be treated as a literal, i.e. no escaping.

For example if your string contains a path you would typically do this:

string path = "c:\\mypath\\to\\myfile.txt";

The @ allows you to do this:

string path = @"c:\mypath\to\myfile.txt";

Notice the lack of double slashes (escaping)

Here are helper functions which allow to convert digit in char to int and vice versa:

int toInt(char c) {
    return c - '0';
}

char toChar(int i) {
    return i + '0';
}

Keith Elder nicely compares ASMX to WCF here. Check it out.

Another comparison of ASMX and WCF can be found here - I don't 100% agree with all the points there, but it might give you an idea.

WCF is basically "ASMX on stereoids" - it can be all that ASMX could - plus a lot more!.

ASMX is:

• easy and simple to write and configure
• only available in IIS
• only callable from HTTP

WCF can be:

• hosted in IIS, a Windows Service, a Winforms application, a console app - you have total freedom
• used with HTTP (REST and SOAP), TCP/IP, MSMQ and many more protocols

In short: WCF is here to replace ASMX fully.

Check out the WCF Developer Center on MSDN.

Just spotted this thread while searching for this very answer. I just made a small jQuery function, hope this helps, works like a charm:

JAVASCRIPT

var maxHeight = 0;
$('.inner').each(function() {
    maxHeight = Math.max(maxHeight, $(this).height());
});
$('.lhs_content .inner, .rhs_content .inner').css({height:maxHeight + 'px'});

HTML

<div class="lhs_content">
    <div class="inner">
        Content in here
    </div>
</div>
<div class="rhs_content">
    <div class="inner">
        More content in here
    </div>
</div>

For integers, there is no difference between pre- and post-increment.

If i is an object of a non-trivial class, then ++i is generally preferred, because the object is modified and then evaluated, whereas i++ modifies after evaluation, so requires a copy to be made.

Why does not it work? Because the background CSS with background:none!important has one #ID

A CSS selector file that contains an #id will always have a higher value than one .class

If you want to work, you need add #id on your .image-list li like this:

#an-element .image-list li {
    display: inline-block;
    background-image: url("http://placekitten.com/150/50")!important;
    padding: 1em;
    border: 1px solid blue;
}

result here

The query to get the nth highest record is as follows:

SELECT 
    *
FROM
    (SELECT 
        *
    FROM
        table_name
    ORDER BY column_name ASC
    LIMIT N) AS tbl
ORDER BY column_name DESC
LIMIT 1;

It's simple and easy to understand

Here is another way to separate your table header and table body:

thead th {
    background-color: #006DCC;
    color: white;
}

tbody td {
    background-color: #EEEEEE;
}

Have a look at this example for separation of head and body of table. JsFiddleLink

If you used...

$(function(){
    function myFunc() {
        // ... do something ...
    };
    $('#saveBtn').click(myFunc);
});

... then it will be easier to unbind later.

$("#name", '#form2').val("Hello World")

Just Adding Another Method-

Replacing Multiple Spaces with Single Space WITHOUT Using REPLACE in SQL Server-

DECLARE @TestTable AS TABLE(input VARCHAR(MAX));

INSERT INTO @TestTable VALUES
('HAPPY         NEWYEAR     2020'),
('WELCOME       ALL     !');

SELECT
    CAST('<r><![CDATA[' + input + ']]></r>' AS XML).value('(/r/text())[1] cast as xs:token?','VARCHAR(MAX)')
    AS Expected_Result
FROM @TestTable;

--OUTPUT
/*
Expected_Result
HAPPY NEWYEAR 2020
WELCOME ALL !
*/

That is working for me. Could be a browser issue as mentioned, or maybe jQuery isn't registered properly, or perhaps the real issue is more complicated (that you made a simpler version to ask this). PS - did have to click out of the text box to make it fire.

http://jsfiddle.net/toddhd/Qt7fH/

$(window).on('load', function () {
 alert('Alert after page load');
        }
    });

I found a solution however you need to know a rough character length that will fit in to your text area, then join a ... to the preceeding space.

The way I did this is to:

1. assume a rough character length (in this case 200) and pass to a function along with your text
2. split the spaces so you have one long string
3. use jQuery to get slice the first " " space after your character length
4. join the remaining ...

code :

truncate = function(description){
        return description.split('').slice(0, description.lastIndexOf(" ",200)).join('') + "...";           
}

here is a fiddle - http://jsfiddle.net/GYsW6/1/

There's Pgloader that uses the aforementioned COPY command and which can load data from csv (and MySQL, SQLite and dBase). It's also using separate threads for reading and copying data, so it's quite fast (interestingly enough, it got written from Python to Common Lisp and got a 20 to 30x speed gain, see blog post).

To load the csv file one needs to write a little configuration file, like

LOAD CSV  
  FROM 'path/to/file.csv' (x, y, a, b, c, d)  
  INTO postgresql:///pgloader?csv (a, b, d, c)  
  …

Imho, writing

python /path/to/script.py

Is quite wrong, especially in these days. Which python? python2.6? 2.7? 3.0? 3.1? Most of times you need to specify the python version in shebang tag of python file. I encourage to use

#!/usr/bin/env python2 #or python2.6 or python3 or even python3.1

In such case, is much better to have the script executable and invoke it directly:

#!/bin/bash

/path/to/script.py

This way the version of python you need is only written in one file. Most of system these days are having python2 and python3 in the meantime, and it happens that the symlink python points to python3, while most people expect it pointing to python2.

Use the code below with the new clear cache commands: php artisan cache clear

//Clear route cache:
 Route::get('/route-cache', function() {
     // EDIT - the linked article uses route:cache, it should be route:clear
     // $exitCode = Artisan::call('route:cache');
     $exitCode = Artisan::call('route:clear');
     return 'Routes cache cleared';
 });

 //Clear config cache:
 Route::get('/config-cache', function() {
     $exitCode = Artisan::call('config:clear');
     return 'Config cache cleared';
 }); 

// Clear application cache:
 Route::get('/clear-cache', function() {
     $exitCode = Artisan::call('cache:clear');
     return 'Application cache cleared';
 });

 // Clear view cache:
 Route::get('/view-clear', function() {
     $exitCode = Artisan::call('view:clear');
     return 'View cache cleared';
 });

In addtion to align-self you can also consider auto margin which will do almost the same thing

.container {_x000D_
  background: red;_x000D_
  height: 200px;_x000D_
  flex-direction: column;_x000D_
  padding: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
a {_x000D_
  margin-right:auto;_x000D_
  padding: 10px 40px;_x000D_
  background: pink;_x000D_
}

<div class="container">_x000D_
  <a href="#">Test</a>_x000D_

I had this problem recently and the problem was that my web server was not configured to serve woff files. For IIS 7, you can select your site, then select the MIME Types icon. If .woff is not in the list, you need to add it. The correct values are

File name extension: .woff
MIME type: application/font-woff

Not with a regular statement, no.

What you can do is wrap the functionality in a PL/pgsql function (or another language, but PL/pgsql seems to be the most appropriate for this), and then just call that function. That means it'll still be a single statement to your app.

Markdown doesn't have a defined syntax to underline text.

I guess this is because underlined text is hard to read, and that it's usually used for hyperlinks.

GitHub is svn compatible so you can use svn ls

svn ls https://github.com/user/repository.git/branches/master/

BitBucket supports git archive so you can download tar archive and list archived files. It is not very efficient but works:

git archive [email protected]:repository HEAD directory | tar -t

Please follow @Sourav's advice.

If after restarting the server you get errors, you may need to set your directory options as well. This is done in the <Directory> tag in httpd.conf. Make sure the final config looks like this:

DocumentRoot "C:\alan"
<Directory "C:\alan">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

This article about CSS image replacement for submit buttons could help.

"Using this method you'll get a clickable image when style sheets are active, and a standard button when style sheets are off. The trick is to apply the image replace methods to a button tag and use it as the submit button, instead of using input.

And since button borders are erased, it's also recommendable change the button cursor to the hand shaped one used for links, since this provides a visual tip to the users."

The CSS code:

#replacement-1 {
  width: 100px;
  height: 55px;
  margin: 0;
  padding: 0;
  border: 0;
  background: transparent url(image.gif) no-repeat center top;
  text-indent: -1000em;
  cursor: pointer; /* hand-shaped cursor */
  cursor: hand; /* for IE 5.x */
}

#replacement-2 {
  width: 100px;
  height: 55px;
  padding: 55px 0 0;
  margin: 0;
  border: 0;
  background: transparent url(image.gif) no-repeat center top;
  overflow: hidden;
  cursor: pointer; /* hand-shaped cursor */
  cursor: hand; /* for IE 5.x */
}
form>#replacement-2 { /* For non-IE browsers*/
  height: 0px;
}

Callback functions :

We define a callback function named callback give it a parameter otherFunction and invoke it inside the function body.

function callback(otherFunction){
    otherFunction();
}

When we invoke callback function it expects an argument of the type function, so we invoke it with an anonymous function. However, it produces an error if the argument is not of type function.

callback(function(){console.log('SUCCESS!')}); 
callback(1); // error

Baking the pizza example. oven to bake pizza base topped with ingredients Now here, oven is the callback function. and pizza base with ingredients is the otherFunction.

Point to note is that different pizza ingredients produce different types of pizzas but the oven which bakes it stays the same. That is somewhat a job of a callback function, which keeps expecting functions with different functionalities in order to produce different custom outcomes.

If you want to check syntax error for any nginx files, you can use the -c option.

[root@server ~]# sudo nginx -t -c /etc/nginx/my-server.conf
nginx: the configuration file /etc/nginx/my-server.conf syntax is ok
nginx: configuration file /etc/nginx/my-server.conf test is successful
[root@server ~]# 

Try This

string path = @"c:\mytext.txt";

if (File.Exists(path))
{
    File.Delete(path);
}

{ // Consider File Operation 1
    FileStream fs = new FileStream(path, FileMode.OpenOrCreate);
    StreamWriter str = new StreamWriter(fs);
    str.BaseStream.Seek(0, SeekOrigin.End);
    str.Write("mytext.txt.........................");
    str.WriteLine(DateTime.Now.ToLongTimeString() + " " + 
                  DateTime.Now.ToLongDateString());
    string addtext = "this line is added" + Environment.NewLine;
    str.Flush();
    str.Close();
    fs.Close();
    // Close the Stream then Individually you can access the file.
}

File.AppendAllText(path, addtext);  // File Operation 2

string readtext = File.ReadAllText(path); // File Operation 3

Console.WriteLine(readtext);

In every File Operation, The File will be Opened and must be Closed prior Opened. Like wise in the Operation 1 you must Close the File Stream for the Further Operations.

This is simply merging. Treat each list as if it were a stack, and continuously pop the smaller of the two stack heads, adding the item to the result list, until one of the stacks is empty. Then add all remaining items to the resulting list.

I know it's an old thread, but I felt compelled to mention the translate method, which is always a good way to replace all character codes above 128 (or other if necessary).

Usage : str.translate(table[, deletechars])

>>> trans_table = ''.join( [chr(i) for i in range(128)] + [' '] * 128 )

>>> 'Résultat'.translate(trans_table)
'R sultat'
>>> '6Â 918Â 417Â 712'.translate(trans_table)
'6  918  417  712'

Starting with Python 2.6, you can also set the table to None, and use deletechars to delete the characters you don't want as in the examples shown in the standard docs at http://docs.python.org/library/stdtypes.html.

With unicode strings, the translation table is not a 256-character string but a dict with the ord() of relevant characters as keys. But anyway getting a proper ascii string from a unicode string is simple enough, using the method mentioned by truppo above, namely : unicode_string.encode("ascii", "ignore")

As a summary, if for some reason you absolutely need to get an ascii string (for instance, when you raise a standard exception with raise Exception, ascii_message ), you can use the following function:

trans_table = ''.join( [chr(i) for i in range(128)] + ['?'] * 128 )
def ascii(s):
    if isinstance(s, unicode):
        return s.encode('ascii', 'replace')
    else:
        return s.translate(trans_table)

The good thing with translate is that you can actually convert accented characters to relevant non-accented ascii characters instead of simply deleting them or replacing them by '?'. This is often useful, for instance for indexing purposes.

This problem happens when you install the JDK by _uncompressing_ it instead of _executing_ it.

By example:

unzip jdk-6u45-linux-x64.bin  (wrong)

sh ./jdk-6u45-linux-x64.bin   (right)

In the first scenario, the runtime libraries, as rt.jar, don't get automatically uncompresessed (thus, you can find the rt.pack files, etc. instead of the .jar ones).

You cant get a decimal value by dividing one integer with another, you'll allways get an integer that way (result truncated to integer). You need at least one value to be a decimal number.

Just Change the Connection mysql string to 127.0.0.1 and it will work

use "Content-type: application/x-www-form-urlencoded" instead of "application/json"

I'm unclear about your question. From http://effbot.org/tkinterbook/entry.htm#patterns, it seems you just need to do an assignment after you called the delete. To add entry text to the widget, use the insert method. To replace the current text, you can call delete before you insert the new text.

e = Entry(master)
e.pack()

e.delete(0, END)
e.insert(0, "")

Could you post a bit more code?

I encourage you to use the -r flag for read which stands for:

-r  Do not treat a backslash character in any special way. Consider each
    backslash to be part of the input line.

I am citing from man 1 read.

Another thing is to take a filename as an argument.

Here is updated code:

#!/usr/bin/bash
filename="$1"
while read -r line; do
    name="$line"
    echo "Name read from file - $name"
done < "$filename"

if you want to remove the latest stash or at any particular index -

git stash drop type_your_index

> git stash list

  stash@{0}: abc
  stash@{1}: xyz
  stash@{1}: pqr

> git stash drop 0

  Dropped refs/stash@{0}

> git stash list

  stash@{0}: xyz
  stash@{1}: pqr

if you want to remove all the stash at once -

> git stash clear
>

> git stash list
>

Warning : Once done you can not revert back your stash

If you're comparing them in unit test, a handy alternative is EqualValues function in testify.

Assuming the file is called "CopyFile.java", do the following:

javac CopyFile.java
java -cp . CopyFile

The first line compiles the source code into executable byte code. The second line executes it, first adding the current directory to the class path (just in case).

The HTTP 502 "Bad Gateway" response is generated when Apache web server does not receive a valid HTTP response from the upstream server, which in this case is your Tomcat web application.

Some reasons why this might happen:

• Tomcat may have crashed
• The web application did not respond in time and the request from Apache timed out
• The Tomcat threads are timing out
• A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system

If the problem is related to timeout settings, you may be able to resolve it by investigating the following:

• ProxyTimeout directive of Apache's mod_proxy
• Connector config of Apache Tomcat
• Your network device's manual

<div ng-controller="ExampleController">
  <form name="myForm">
    <label for="repeatSelect"> Repeat select: </label>
    <select name="repeatSelect" id="repeatSelect" ng-model="data.model">
      <option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
    </select>
  </form>
  <hr>
  <tt>model = {{data.model}}</tt><br/>
</div>

AngularJS:

angular.module('ngrepeatSelect', [])
 .controller('ExampleController', ['$scope', function($scope) {
   $scope.data = {
    model: null,
    availableOptions: [
      {id: '1', name: 'Option A'},
      {id: '2', name: 'Option B'},
      {id: '3', name: 'Option C'}
    ]
   };
}]);

Perhaps I'm missing something but why doesn't this work with the SEQUENCE object? Is this not what you're looking for?

Example:

CREATE SCHEMA blah.
GO

CREATE SEQUENCE blah.blahsequence
START WITH 1
INCREMENT BY 1
NO CYCLE;

CREATE TABLE blah.de_blah_blah
(numbers bigint PRIMARY KEY NOT NULL
......etc

When referencing the squence in say an INSERT command just use:

NEXT VALUE FOR blah.blahsequence

Amazon EC2 instances are just virtual machines so you would setup SSL the same way you would set it up on any server.

You don't mention what platform you are on, so it difficult to give any more information.

ASCII is a subset of UTF-8, so all ASCII files are already UTF-8 encoded. The bytes in the ASCII file and the bytes that would result from "encoding it to UTF-8" would be exactly the same bytes. There's no difference between them, so there's no need to do anything.

It looks like your problem is that the files are not actually ASCII. You need to determine what encoding they are using, and transcode them properly.

I am surprise, no one here has ans by using simple javascript and Set logic to automatically filter the duplicates values, simple example on mongo shellas below:

var allKeys = new Set()
db.collectionName.find().forEach( function (o) {for (key in o ) allKeys.add(key)})
for(let key of allKeys) print(key)

This will print all possible unique keys in the collection name: collectionName.

An easy way which allows you to omit any parameters in any position, is taking advantage of nullable types as follows:

public void PrintValues(int? a = null, int? b = null, float? c = null, string s = "")
{
    if(a.HasValue)
        Console.Write(a);
    else
        Console.Write("-");

    if(b.HasValue)
        Console.Write(b);
    else
        Console.Write("-");

    if(c.HasValue)
        Console.Write(c);
    else
        Console.Write("-");

    if(string.IsNullOrEmpty(s)) // Different check for strings
        Console.Write(s);
    else
        Console.Write("-");
}

Strings are already nullable types so they don't need the ?.

Once you have this method, the following calls are all valid:

PrintValues (1, 2, 2.2f);
PrintValues (1, c: 1.2f);
PrintValues(b:100);
PrintValues (c: 1.2f, s: "hello");
PrintValues();

When you define a method that way you have the freedom to set just the parameters you want by naming them. See the following link for more information on named and optional parameters:

Named and Optional Arguments (C# Programming Guide) @ MSDN

Here is a talk about the differences between web sockets and server sent events. Since Java EE 7 a WebSocket API is already part of the specification and it seems that server sent events will be released in the next version of the enterprise edition.

Please try the below query. Use sys.columns to get the details :-

SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
    JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyCol%';

If your compiler supports (at least part of) C++11 you could do something like:

for (auto& t : myMap)
    std::cout << t.first << " " 
              << t.second.first << " " 
              << t.second.second << "\n";

For C++03 I'd use std::copy with an insertion operator instead:

typedef std::pair<string, std::pair<string, string> > T;

std::ostream &operator<<(std::ostream &os, T const &t) { 
    return os << t.first << " " << t.second.first << " " << t.second.second;
}

// ...
std:copy(myMap.begin(), myMap.end(), std::ostream_iterator<T>(std::cout, "\n"));

If you use Guava (former Google Collections) library there is a solution:

SetView<Number> difference = com.google.common.collect.Sets.difference(test2, test1);

The returned SetView is a Set, it is a live representation you can either make immutable or copy to another set. test1 and test2 are left intact.

You could use a label (see JsFiddle)

CSS

label { display: inline-block; width: 210px; text-align: right; }

HTML

<html> 
    <label for="name">Name:</label><input id="name" type="text"><br />
    <label for="email">Email Address:</label><input id="email" type="text"><br /> 
    <label for="desc">Description of the input value:</label><input id="desc" type="text"><br /> 
 </html> 

Or you could use those labels in a table (JsFiddle)

<html>
    <table>
        <tbody>
            <tr><td><label for="name">Name:</label></td><td><input id="name" type="text"></td></tr>
            <tr><td><label for="email">Email Address:</label></td><td><input id="email" type = "text"></td></tr>
            <tr><td><label for="desc">Description of the input value:</label></td><td><input id="desc" type="text"></td></tr>
        </tbody>
    </table>
 </html> 

From the MSDN page on StackOverflowExceptions:

In prior versions of the .NET Framework, your application could catch a StackOverflowException object (for example, to recover from unbounded recursion). However, that practice is currently discouraged because significant additional code is required to reliably catch a stack overflow exception and continue program execution.

Starting with the .NET Framework version 2.0, a StackOverflowException object cannot be caught by a try-catch block and the corresponding process is terminated by default. Consequently, users are advised to write their code to detect and prevent a stack overflow. For example, if your application depends on recursion, use a counter or a state condition to terminate the recursive loop. Note that an application that hosts the common language runtime (CLR) can specify that the CLR unload the application domain where the stack overflow exception occurs and let the corresponding process continue. For more information, see ICLRPolicyManager Interface and Hosting the Common Language Runtime.

In this part of your SP:

IF @DateFirst <> '' and @DateLast <> ''
   set @FinalSQL  = @FinalSQL
       + '  or convert (Date,DateLog) >=     ''' + @DateFirst
       + ' and convert (Date,DateLog) <=''' + @DateLast  

you are trying to concatenate strings and datetimes.

As the datetime type has higher priority than varchar/nvarchar, the + operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= ''' and others) to datetime or numeric values. And fails.

That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.

To amend the situation, you need to add explicit casting of your datetime variables to strings:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst)
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)

You'll also need to add closing single quotes:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst) + ''''
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''

UPDATE: As Brad Parks wrote in his comment there is a much better and easier solution with only one line of JS code:

run setTimeout(function(){debugger;},5000);, then go show your element and wait until it breaks into the Debugger

Original answer:

I just had the same problem, and I think I found an "universal" solution. (assuming the site uses jQuery)
Hope it helps someone!

1. Go to elements tab in inspector
2. Right click <body> and click "Edit as HTML"
3. Add the following element after <body> then press Ctrl+Enter:
   <div id="debugFreeze" data-rand="0"></div>
4. Right click this new element, and select "Break on..." -> "Attributes modifications"
5. Now go to Console view and run the following command:
   setTimeout(function(){$("#debugFreeze").attr("data-rand",Math.random())},5000);
6. Now go back to the browser window and you have 5 seconds to find your element and click/hover/focus/etc it, before the breakpoint will be hit and the browser will "freeze".
7. Now you can inspect your clicked/hovered/focused/etc element in peace.

Of course you can modify the javascript and the timing, if you get the idea.

In simple words v-model is for two way bindings means: if you change input value, the bound data will be changed and vice versa.

but v-bind:value is called one way binding that means: you can change input value by changing bound data but you can't change bound data by changing input value through the element.

check out this simple example: https://jsfiddle.net/gs0kphvc/

You should construct your string as URI object and Authority property returns what you need.

I don't Know you use any Bootstrap version but the useful helper class for centering and block an element in center it is .center-block because this class contain margin and display CSS properties but the .text-center class only contain the text-align property

Bootstrap Helper Class center-block

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

As suggested by the homebrew installer itself, be sure to add this to your .bashrc or .zshrc:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

According to Vlad Mihalcea (see https://vladmihalcea.com/hibernate-facts-the-importance-of-fetch-strategy/):

JPQL queries may override the default fetching strategy. If we don’t explicitly declare what we want to fetch using inner or left join fetch directives, the default select fetch policy is applied.

It seems that JPQL query might override your declared fetching strategy so you'll have to use join fetch in order to eagerly load some referenced entity or simply load by id with EntityManager (which will obey your fetching strategy but might not be a solution for your use case).

You have a couple of options:

1. Scope the domain down (see document.domain) in both the containing page and the iframe to the same thing. Then they will not be bound by 'same origin' constraints.

2. Use postMessage which is supported by all HTML5 browsers for cross-domain communication.

For me, the user was mongod instead of mongodb

sudo chown mongod:mongod /newlocation

You can see the logs for errors if the service fails:

/var/log/mongodb/mongod.log

You can get the query parameters when passed in URL using ActivatedRoute as stated below:-

url:- http:/domain.com?test=abc

import { Component } from '@angular/core';
import { ActivatedRoute }     from '@angular/router';

@Component({
  selector: 'my-home'
})
export class HomeComponent {

  constructor(private sharedServices : SharedService,private route: ActivatedRoute) { 
    route.queryParams.subscribe(
      data => console.log('queryParams', data['test']));
  }

}

You can also try this

string.Join(null,System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]"));

What about:

.close-image{
    display:block;
    cursor:pointer;
    z-index:3;
    position:absolute;
    top:0;
    right:0;
}

Is that the desired result?

It's about classes dependency rate to another ones which is so low in loosely coupled and so high in tightly coupled. To be clear in the service orientation architecture, services are loosely coupled to each other against monolithic which classes dependency to each other is on purpose

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

You will probably get an UAC prompt when importing the reg file. If you accept that, you have more rights.

Since you are writing to the 'policies' key, you need to have elevated rights. This part of the registry protected, because it contains settings that are administered by your system administrator.

Alternatively, you may try to run regedit.exe from the command prompt.

regedit.exe /S yourfile.reg

.. should silently import the reg file. See RegEdit Command Line Options Syntax for more command line options.

you could use

    line-height:35px;

You really shouldnt set a height on paragraph as its not good for accessibility (what happens if the user increase text size etc)

Instead use a Div with a hight and the p inside it with the correct line-height:

    <div style="height:35px;"><p style="line-height:35px;">text</p></div>

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

Python strings are immutable and hence have more complex handling when talking about its operations. Note that a string with spaces is actually an empty string but has a non-zero size. Let’s see two different methods of checking if string is empty or not: Method #1 : Using Len() Using Len() is the most generic method to check for zero-length string. Even though it ignores the fact that a string with just spaces also should be practically considered as an empty string even its non-zero.

Method #2 : Using not

Not operator can also perform the task similar to Len(), and checks for 0 length string, but same as the above, it considers the string with just spaces also to be non-empty, which should not practically be true.

Good Luck!

Have a look at another of mine, more in-depth answer: https://stackoverflow.com/a/57723549/3049675

While I agree that in general inline-block is better, there's one extra thing to take into account if you're using percentage widths to create a responsive grid (or if you want pixel-perfect widths):

If you're using inline-block for grids that total 100% or near to 100% width, you need to make sure your HTML markup contains no white space between columns.

With floats, this is not something you need to worry about - the columns float over any whitespace or other content between columns. This question's answers have some good tips on ways to remove HTML whitespace without making your code ugly.

If for any reason you can't control the HTML markup (e.g. a restrictive CMS), you can try the tricks described here, or you might need to compromise and use floats instead of inline-block. There are also ugly CSS tricks that should only be used in extreme circumstances, like font-size:0; on the column container then reapply font size within each column.

For example:

• Here's a 3-column grid of 33.3% width with float: left. It "just works" (but for the wrapper needing to be cleared).
• Here's the exact same grid, with inline-block. The whitespace between blocks creates a fixed-width space which pushes the total width beyond 100%, breaking the layout and causing the last column to drop down a line.
• Here' s the same grid, with inline-block and no whitespace between columns in the HTML. It "just works" again - but the HTML is uglier and your CMS might force some kind of prettification or indenting to its HTML output making this difficult to achieve in reality.

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob;

Use string instead of string? in all places in your code.

The Nullable<T> type requires that T is a non-nullable value type, for example int or DateTime. Reference types like string can already be null. There would be no point in allowing things like Nullable<string> so it is disallowed.

Also if you are using C# 3.0 or later you can simplify your code by using auto-implemented properties:

public class WordAndMeaning
{
    public string Word { get; set; }
    public string Meaning { get; set; }
}

I also like to wrap session variables in properties. The setters here are trivial, but I like to write the get methods so they have only one exit point. To do that I usually check for null and set it to a default value before returning the value of the session variable. Something like this:

string Name
{
   get 
   {
       if(Session["Name"] == Null)
           Session["Name"] = "Default value";
       return (string)Session["Name"];
   }
   set { Session["Name"] = value; }
}

}

COALESCE is more modern function that is a part of ANSI-92 standard.

NVL is Oracle specific, it was introduced in 80's before there were any standards.

In case of two values, they are synonyms.

However, they are implemented differently.

NVL always evaluates both arguments, while COALESCE usually stops evaluation whenever it finds the first non-NULL (there are some exceptions, such as sequence NEXTVAL):

SELECT  SUM(val)
FROM    (
        SELECT  NVL(1, LENGTH(RAWTOHEX(SYS_GUID()))) AS val
        FROM    dual
        CONNECT BY
                level <= 10000
        )

This runs for almost 0.5 seconds, since it generates SYS_GUID()'s, despite 1 being not a NULL.

SELECT  SUM(val)
FROM    (
        SELECT  COALESCE(1, LENGTH(RAWTOHEX(SYS_GUID()))) AS val
        FROM    dual
        CONNECT BY
                level <= 10000
        )

This understands that 1 is not a NULL and does not evaluate the second argument.

SYS_GUID's are not generated and the query is instant.

The trick is to have an algorithm that only you know (such that it could be decoded at the other end).

There are simple things like, "Pick a prime number and add a magic number to it"

More convoluted options such as using asymmetric encryption of a set of binary data (that could include a unique identifier, version numbers, etc) and distribute the encrypted data as the key.

Might also be worth reading the responses to this question as well

I personally didn't find any of these answers helpful. What worked in my case was giving the element float:none and position:relative. After that the element centered itself in the <td>.

For "BEFORE popping the view off the stack" :

- (void)willMoveToParentViewController:(UIViewController *)parent{
    if (parent == nil){
        NSLog(@"do whatever you want here");
    }
}

select t1.* from 
(select * from TABLE Where CCC='D' AND DDD='X') as t1,
(select * from TABLE Where CCC<>'D' AND DDD='X') as t2

Another way to do this!

A bit late to the game for this question, but in recent changes introduced in C# 7 (Available by default in Visual Studio 2017/.NET Framework 4.6.2), range-based switching is now possible with the switch statement.

Example:

int i = 63;

switch (i)
{
    case int n when (n >= 100):
        Console.WriteLine($"I am 100 or above: {n}");
        break;

    case int n when (n < 100 && n >= 50 ):
        Console.WriteLine($"I am between 99 and 50: {n}");
        break;

    case int n when (n < 50):
        Console.WriteLine($"I am less than 50: {n}");
        break;
}

Notes:

• The parentheses ( and ) are not required in the when condition, but are used in this example to highlight the comparison(s).
• var may also be used in lieu of int. For example: case var n when n >= 100:.

jQuery.css() returns sizes in pixels, even if the CSS itself specifies them in em, or as a percentage, or whatever. It appends the units ('px'), but you can nevertheless use parseInt() to convert them to integers (or parseFloat(), for where fractions of pixels make sense).

http://jsfiddle.net/BXnXJ/

    $(document).ready(function () {
    var $h1 = $('h1');
    console.log($h1);
    $h1.after($('<div>Padding-top: ' + parseInt($h1.css('padding-top')) + '</div>'));
    $h1.after($('<div>Margin-top: ' + parseInt($h1.css('margin-top')) + '</div>'));
});

if you have json in your dependencies.you can use new JSONArray(list).toString()

You should escape the quotes like this:

curl -i -X POST -d '{\"screencast\":{\"subject\":\"tools\"}}'  \
  http://localhost:3570/index.php/trainingServer/screencast.json

user double quote to get the exact value. like this:

echo "${var}"

and it will read your value correctly.

You should use System.Windows.Forms.Cursor.Position: "A Point that represents the cursor's position in screen coordinates."

Here is some code to do just that. Haven't tried it out myself...

The most up-to-date answer to this is: they are listed under the 'Network' button in the developer tools, no longer under 'Resources' like it used to be.

First things first, hover the mouse over the grey area below. Not part of the answer, but absolutely has to be said:

If you have a shell script that does "checkout, build, deploy" all by itself, then why are you using Jenkins? You are foregoing all the features of Jenkins that make it what it is. You might as well have a cron or an SVN post-commit hook call the script directly. Jenkins performing the SVN checkout itself is crucial. It allows the builds to be triggered only when there are changes (or on timer, or manual, if you prefer). It keeps track of changes between builds. It shows those changes, so you can see which build was for which set of changes. It emails committers when their changes caused successful or failed build (again, as configured as you prefer). It will email committers when their fixes fixed the failing build. And more and more. Jenkins archiving the artifacts also makes them available, per build, straight off Jenkins. While not as crucial as the SVN checkout, this is once again an integral part of what makes it Jenkins. Same with deploying. Unless you have a single environment, deployment usually happens to multiple environments. Jenkins can keep track of which environment a specific build (with specific set of SVN changes) is deployed it, through the use of Promotions. You are foregoing all of this. It sounds like you are told "you have to use Jenkins" but you don't really want to, and you are doing it just to get your bosses off your back, just to put a checkmark "yes, I've used Jenkins"

The short answer is: the exit code of last command of the Jenkin's Execute Shell build step is what determines the success/failure of the Build Step. 0 - success, anything else - failure. Note, this is determining the success/failure of the build step, not the whole job run. The success/failure of the whole job run can further be affected by multiple build steps, and post-build actions and plugins.

You've mentioned Build step 'Execute shell' marked build as failure, so we will focus just on a single build step. If your Execute shell build step only has a single line that calls your shell script, then the exit code of your shell script will determine the success/failure of the build step. If you have more lines, after your shell script execution, then carefully review them, as they are the ones that could be causing failure.

Finally, have a read here Jenkins Build Script exits after Google Test execution. It is not directly related to your question, but note that part about Jenkins launching the Execute Shell build step, as a shell script with /bin/sh -xe

The -e means that the shell script will exit with failure, even if just 1 command fails, even if you do error checking for that command (because the script exits before it gets to your error checking). This is contrary to normal execution of shell scripts, which usually print the error message for the failed command (or redirect it to null and handle it by other means), and continue.

To circumvent this, add set +e to the top of your shell script.

Since you say your script does all it is supposed to do, chances are the failing command is somewhere at the end of the script. Maybe a final echo? Or copy of artifacts somewhere? Without seeing the full console output, we are just guessing.

Please post the job run's console output, and preferably the shell script itself too, and then we could tell you exactly which line is failing.

I've always used this syntax, which yields more predictable results than using !=.

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')" />

What you're saying here is you want to have one that uses has collision resistance. Try using SHA-2. Or try using a (good) block cipher in a one way compression function (never tried that before), like AES in Miyaguchi-Preenel mode. The problem with that is that you need to:

1) have an IV. Try using the first 256 bits of the fractional parts of Khinchin's constant or something like that. 2) have a padding scheme. Easy. Barrow it from a hash like MD5 or SHA-3 (Keccak [pronounced 'ket-chak']). If you don't care about the security (a few others said this), look at FNV or lookup2 by Bob Jenkins (actually I'm the first one who reccomends lookup2) Also try MurmurHash, it's fast (check this: .16 cpb).

I had similar issue recently. Regional settings were properly setup both in app and database server. However, execution of SQL resulted in

"The conversion of a varchar data type to a datetime data type resulted in an out-of-range value".

The problem was the default language of the db user.

To check or change it in SSMS go to Security -> Logins and right-click the username of the user that runs the queries. Select properties -> general and make sure the default language at the bottom of the dialog is what you expect.

Repeat this for all users that run queries.

I resolved this issue after deleting folder where I was trying to add the file in Visual Studio. Deleted folder from window explorer also. After doing all this, successfully able to add folder and file.

Cache.delete() can be used for new chrome, firefox and opera.

I've written this little plugin for jQuery which will make all calls to .val(value) update the angular element if present:

(function($, ng) {
  'use strict';

  var $val = $.fn.val; // save original jQuery function

  // override jQuery function
  $.fn.val = function (value) {
    // if getter, just return original
    if (!arguments.length) {
      return $val.call(this);
    }

    // get result of original function
    var result = $val.call(this, value);

    // trigger angular input (this[0] is the DOM object)
    ng.element(this[0]).triggerHandler('input');

    // return the original result
    return result; 
  }
})(window.jQuery, window.angular);

Just pop this script in after jQuery and angular.js and val(value) updates should now play nice.

Minified version:

!function(n,t){"use strict";var r=n.fn.val;n.fn.val=function(n){if(!arguments.length)return r.call(this);var e=r.call(this,n);return t.element(this[0]).triggerHandler("input"),e}}(window.jQuery,window.angular);

A more thorough solution

The core of this is the replace call. So far, I don't think any of the proposed solutions handle all of the following cases:

• Integers: 1000 => '1,000'
• Strings: '1000' => '1,000'
• For strings:
  • Preserves zeros after decimal: 10000.00 => '10,000.00'
  • Discards leading zeros before decimal: '01000.00 => '1,000.00'
  • Does not add commas after decimal: '1000.00000' => '1,000.00000'
  • Preserves leading - or +: '-1000.0000' => '-1,000.000'
  • Returns, unmodified, strings containing non-digits: '1000k' => '1000k'

The following function does all of the above.

addCommas = function(input){
  // If the regex doesn't match, `replace` returns the string unmodified
  return (input.toString()).replace(
    // Each parentheses group (or 'capture') in this regex becomes an argument 
    // to the function; in this case, every argument after 'match'
    /^([-+]?)(0?)(\d+)(.?)(\d+)$/g, function(match, sign, zeros, before, decimal, after) {

      // Less obtrusive than adding 'reverse' method on all strings
      var reverseString = function(string) { return string.split('').reverse().join(''); };

      // Insert commas every three characters from the right
      var insertCommas  = function(string) { 

        // Reverse, because it's easier to do things from the left
        var reversed           = reverseString(string);

        // Add commas every three characters
        var reversedWithCommas = reversed.match(/.{1,3}/g).join(',');

        // Reverse again (back to normal)
        return reverseString(reversedWithCommas);
      };

      // If there was no decimal, the last capture grabs the final digit, so
      // we have to put it back together with the 'before' substring
      return sign + (decimal ? insertCommas(before) + decimal + after : insertCommas(before + after));
    }
  );
};

You could use it in a jQuery plugin like this:

$.fn.addCommas = function() {
  $(this).each(function(){
    $(this).text(addCommas($(this).text()));
  });
};

If your jar file already has an absolute pathname as shown, it is particularly easy:

cd /where/you/want/it; jar xf /path/to/jarfile.jar

That is, you have the shell executed by Python change directory for you and then run the extraction.

If your jar file does not already have an absolute pathname, then you have to convert the relative name to absolute (by prefixing it with the path of the current directory) so that jar can find it after the change of directory.

The only issues left to worry about are things like blanks in the path names.

For me this worked.
