When you are in the Command, click Create to create a new parameter; call it project_name. Once you've created it, double click its name to add it to the command's text. You query should resemble:

SELECT Projecttname, ReleaseDate, TaskName
FROM DB_Table
WHERE Project_Name LIKE {?project_name} + '*'
AND ReleaseDate >= getdate() --assumes sql server

If desired, link the main report to the subreport on this ({?project_name}) field. If you don't establish a link between the main and subreport, CR will prompt you for the subreport's parameter.

In versions prior to 2008, a command's parameter was only allowed to be a scalar value.

If you want to remove the default value constraint, you can do:

ALTER TABLE <table> ALTER COLUMN <column> DROP DEFAULT;

There are some code differences to be aware of.

A negative first parameter to subtr is not supported, e.g. in Javascript: "string".substr(-1) returns "g", whereas in JScript: "string".substr(-1) returns "string"

It's possible to do "string"[0] to get "s" in Javascript, but JScript doesn't support such a construct. (Actually, only modern browsers appear to support the "string"[0] construct.

$('#abc').css({"display":"none"});

this hides the content and also does not leave empty space.

If the binding needs to be two-way, you must supply a path.

There's a trick to do two-way binding on a static property, provided the class is not static : declare a dummy instance of the class in the resources, and use it as the source of the binding.

<Window.Resources>
    <local:VersionManager x:Key="versionManager"/>
</Window.Resources>
...

<TextBox Text="{Binding Source={StaticResource versionManager}, Path=FilterString}"/>

With IntelliJ IDEA you can create a Jar Application runtime configuration, select the JAR, the sources, the JRE to run the Jar with and start debugging. Here is the documentation.

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

If you are using JDK 6 then you might want to check out ConcurrentHashMap

Note the putIfAbsent method in that class.

Agreed with part of @Jeffrey Fox's answer:

max-age=0, must-revalidate and no-cache aren't exactly identical.

Not agreed with this part:

With no-cache, it would just show the cached content, which would be probably preferred by the user (better to have something stale than nothing at all).

What should implementations do when cache-control: no-cache revalidation failed is just not specified in the RFC document. It's all up to implementations. They may throw a 504 error like cache-control: must-revalidate or just serve a stale copy from cache.

#!/bin/bash

variable=`ps -ef | grep "port 10 -" | grep -v "grep port 10 -" | awk '{printf $12}'`
echo $variable

Notice that there's no space after the equal sign.

You can also use $() which allows nesting and is readable.

Here is my sample how I use it. For the css/less task. Can be applied for all.

var cssTask = function (options) {
  var minifyCSS = require('gulp-minify-css'),
    less = require('gulp-less'),
    src = cssDependencies;

  src.push(codePath + '**/*.less');

  var run = function () {
    var start = Date.now();

    console.log('Start building CSS/LESS bundle');

    gulp.src(src)
      .pipe(gulpif(options.devBuild, plumber({
        errorHandler: onError
      })))
      .pipe(concat('main.css'))
      .pipe(less())
      .pipe(gulpif(options.minify, minifyCSS()))
      .pipe(gulp.dest(buildPath + 'css'))
      .pipe(gulpif(options.devBuild, browserSync.reload({stream:true})))
      .pipe(notify(function () {
        console.log('END CSS/LESS built in ' + (Date.now() - start) + 'ms');
      }));
  };

  run();

  if (options.watch) {
    gulp.watch(src, run);
  }
};

gulp.task('dev', function () {
  var options = {
    devBuild: true,
    minify: false,
    watch: false
  };

  cssTask (options);
});

The align-items property of flex-box aligns the items inside a flex container along the cross axis just like justify-content does along the main axis. (For the default flex-direction: row the cross axis corresponds to vertical and the main axis corresponds to horizontal. With flex-direction: column those two are interchanged respectively).

Here's an example of how align-items:center looks:

But align-content is for multi line flexible boxes. It has no effect when items are in a single line. It aligns the whole structure according to its value. Here's an example for align-content: space-around;:

And here's how align-content: space-around; with align-items:center looks:

Note the 3rd box and all other boxes in first line change to vertically centered in that line.

If you prefer to resolve timestamps and dates conversions from and to UTC and local time without libraries like moment.js, take a look at the option below.

For applications that use UTC timestamps, you may need to show the date in the browser considering the local timezone and daylight savings when applicable. Editing a date that is in a different daylight savings time even though in the same timezone can be tricky.

The Number and Date extensions below allow you to show and get dates in the timezone of the timestamps. For example, lets say you are in Vancouver, if you are editing a date in July or in December, it can mean you are editing a date in PST or PDT.

I recommend you to check the Code Snippet down below to test this solution.

Conversions from milliseconds

Number.prototype.toLocalDate = function () {
    var value = new Date(this);

    value.setHours(value.getHours() + (value.getTimezoneOffset() / 60));

    return value;
};

Number.prototype.toUTCDate = function () {
    var value = new Date(this);

    value.setHours(value.getHours() - (value.getTimezoneOffset() / 60));

    return value;
};

Conversions from dates

Date.prototype.getUTCTime = function () {
    return this.getTime() - (this.getTimezoneOffset() * 60000);
};

Usage

// Adds the timezone and daylight savings if applicable
(1499670000000).toLocalDate();

// Eliminates the timezone and daylight savings if applicable
new Date(2017, 6, 10).getUTCTime();

Perhaps you can do it while registering your root with RouterModule. You can pass a second object with property useHash:true like the below:

import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { ROUTES }   from './app.routes';

@NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule],
    RouterModule.forRoot(ROUTES ,{ useHash: true }),],
    providers: [],
    bootstrap: [AppComponent],
})
export class AppModule {}

Storing a list of object instances is very simple

class MyClass(object):
    def __init__(self, number):
        self.number = number

my_objects = []

for i in range(100):
    my_objects.append(MyClass(i))

# later

for obj in my_objects:
    print obj.number

If you're using django, you can use urlquote:

>>> from django.utils.http import urlquote
>>> urlquote(u"Müller")
u'M%C3%BCller'

Note that changes to Python since this answer was published mean that this is now a legacy wrapper. From the Django 2.1 source code for django.utils.http:

A legacy compatibility wrapper to Python's urllib.parse.quote() function.
(was used for unicode handling on Python 2)

To install a new package and only that, you have two options:

1. Using the require command, just run:

   composer require new/package
   

   Composer will guess the best version constraint to use, install the package, and add it to composer.lock.

   You can also specify an explicit version constraint by running:

   composer require new/package ~2.5
   

–OR–

2. Using the update command, add the new package manually to composer.json, then run:

   composer update new/package
   

If Composer complains, stating "Your requirements could not be resolved to an installable set of packages.", you can resolve this by passing the flag --with-dependencies. This will whitelist all dependencies of the package you are trying to install/update (but none of your other dependencies).

Regarding the question asker's issues with Laravel and mcrypt: check that it's properly enabled in your CLI php.ini. If php -m doesn't list mcrypt then it's missing.

Important: Don't forget to specify new/package when using composer update! Omitting that argument will cause all dependencies, as well as composer.lock, to be updated.

Today, in Office 365, Excel has so called 'array functions'. The filter function does exactly what you want. No need to use CTRL+SHIFT+ENTER anymore, a simple enter will suffice.

In Office 365, your problem would be simply solved by using:

=VLOOKUP(A3, FILTER(A2:C6, B2:B6="B"), 3, FALSE)

You can run webpack twice with different arguments:

$ webpack --minimize

then check command line arguments in webpack.config.js:

var path = require('path'),
  webpack = require('webpack'),
  minimize = process.argv.indexOf('--minimize') !== -1,
  plugins = [];

if (minimize) {
  plugins.push(new webpack.optimize.UglifyJsPlugin());
}

...

Use control anchoring. Set property Anchor of your GridView to Top, Left, Right and it will resize with container. If your GridView are placed inside of some container (ex Panel) then Panel should be anchored too.

I would save that session cookie as a preference and forcefully repopulate the cookie manager with it. It sounds that session cookie in not surviving Activity restart

I found a much easier way, which allows you to still use the built in sorting/paging of the standard gridview...

create 2 labels. set them to be visible = false. I called mine lblSort1 and lblSortDirection1

then code 2 simple events... the page sorting, which writes to the text of the invisible labels, and the page index changing, which uses them...

Private Sub gridview_Sorting(sender As Object, e As GridViewSortEventArgs) Handles gridview.Sorting
lblSort1.Text = e.SortExpression
lblSortDirection1.Text = e.SortDirection
End Sub

Private Sub gridview_PageIndexChanging(sender As Object, e As GridViewPageEventArgs) Handles gridview.PageIndexChanging
    gridview.Sort(lblSort1.Text, CInt(lblSortDirection1.Text))
End Sub

this is a little sloppier than using global variables, but I've found with asp especially that global vars are, well, unreliable...

You can use the substr function like this:

echo substr($myStr, 0, 5);

The second argument to substr is from what position what you want to start and third arguments is for how many characters you want to return.

The traditional approach is full of boilerplate code and clumsy resource handling. That's why I made the Spyglass framework. To demonstrate how it works, here's an example showing how to make a custom view that displays a String title.

Step 1: Create a custom view class.

public class CustomView extends FrameLayout {
    private TextView titleView;

    public CustomView(Context context) {
        super(context);
        init(null, 0, 0);
    }

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(attrs, 0, 0);
    }

    public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(attrs, defStyleAttr, 0);
    }

    @RequiresApi(21)
    public CustomView(
            Context context, 
            AttributeSet attrs,
            int defStyleAttr,
            int defStyleRes) {

        super(context, attrs, defStyleAttr, defStyleRes);
        init(attrs, defStyleAttr, defStyleRes);
    }

    public void setTitle(String title) {
        titleView.setText(title);
    }

    private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        inflate(getContext(), R.layout.custom_view, this);

        titleView = findViewById(R.id.title_view);
    }
}

Step 2: Define a string attribute in the values/attrs.xml resource file:

<resources>
    <declare-styleable name="CustomView">
        <attr name="title" format="string"/>
    </declare-styleable>
</resources>

Step 3: Apply the @StringHandler annotation to the setTitle method to tell the Spyglass framework to route the attribute value to this method when the view is inflated.

@HandlesString(attributeId = R.styleable.CustomView_title)
public void setTitle(String title) {
    titleView.setText(title);
}

Now that your class has a Spyglass annotation, the Spyglass framework will detect it at compile-time and automatically generate the CustomView_SpyglassCompanion class.

Step 4: Use the generated class in the custom view's init method:

private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    inflate(getContext(), R.layout.custom_view, this);

    titleView = findViewById(R.id.title_view);

    CustomView_SpyglassCompanion
            .builder()
            .withTarget(this)
            .withContext(getContext())
            .withAttributeSet(attrs)
            .withDefaultStyleAttribute(defStyleAttr)
            .withDefaultStyleResource(defStyleRes)
            .build()
            .callTargetMethodsNow();
}

That's it. Now when you instantiate the class from XML, the Spyglass companion interprets the attributes and makes the required method call. For example, if we inflate the following layout then setTitle will be called with "Hello, World!" as the argument.

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:width="match_parent"
    android:height="match_parent">

    <com.example.CustomView
        android:width="match_parent"
        android:height="match_parent"
        app:title="Hello, World!"/>
</FrameLayout>

The framework isn't limited to string resources has lots of different annotations for handling other resource types. It also has annotations for defining default values and for passing in placeholder values if your methods have multiple parameters.

Have a look at the Github repo for more information and examples.

Trying to connect to your local computer.try with the hostname "localhost" instead or perhaps ::/ - the last one is ipv6

The secret is simple: Ctrl+Shift+F

Try this too

 $url = 'http://www.domain.com/';
    $html = file_get_contents($url);

    //Change encoding to UTF-8 from ISO-8859-1
    $html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $html);

If your data is always going to be repeatable, perhaps don't worry about it. However, you can unroll it too - this is especially useful if the incoming data could be large (for example, reading from disk/network):

if(objects == null) throw new ArgumentException();
using(var iter = objects.GetEnumerator()) {
    if(!iter.MoveNext()) throw new ArgumentException();

    var firstObject = iter.Current;
    var list = DoSomeThing(firstObject);  

    while(iter.MoveNext()) {
        list.Add(DoSomeThingElse(iter.Current));
    }
    return list;
}

Note I changed the semantic of DoSomethingElse a bit, but this is mainly to show unrolled usage. You could re-wrap the iterator, for example. You could make it an iterator block too, which could be nice; then there is no list - and you would yield return the items as you get them, rather than add to a list to be returned.

To build on @dyslexicanaboko's answer for dotnet core, here is a client console application:

Create a helper class:

using System;
using Microsoft.AspNetCore.SignalR.Client;

namespace com.stackoverflow.SignalRClientConsoleApp
{
    public class SignalRConnection
    {
        public async void Start()
        {
            var url = "http://signalr-server-url/hubname";

            var connection = new HubConnectionBuilder()
                .WithUrl(url)
                .WithAutomaticReconnect()
                .Build();

            // receive a message from the hub
            connection.On<string, string>("ReceiveMessage", (user, message) => OnReceiveMessage(user, message));

            var t = connection.StartAsync();

            t.Wait();

            // send a message to the hub
            await connection.InvokeAsync("SendMessage", "ConsoleApp", "Message from the console app");
        }

        private void OnReceiveMessage(string user, string message)
        {
            Console.WriteLine($"{user}: {message}");
        }

    }
}

Then implement in your console app's entry point:

using System;

namespace com.stackoverflow.SignalRClientConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var signalRConnection = new SignalRConnection();
            signalRConnection.Start();

            Console.Read();
        }
    }
}

I was facing some difficulties with an environment variable that is with custom name (not with container name /port convention for KAPACITOR_BASE_URL and KAPACITOR_ALERTS_ENDPOINT). If we give service name in this case it wouldn't resolve the ip as

KAPACITOR_BASE_URL:  http://kapacitor:9092

In above http://[**kapacitor**]:9092 would not resolve to http://172.20.0.2:9092

Thanks to SwiftBoy's 10-step solution I successfully used CocoaPods to setup the latest version of AudioKit.

1. Using Xcode create MyAudioApp Swift project saving it to my Developer directory e.g.

    /Users/me/Developer/MyAudioApp

2. Using Cocoapods install AudioKit within MyAudioApp project (i.e. install AudioKit sdk)

3. Open Terminal, type command below and press Enter

    sudo gem install -n /usr/local/bin cocoapods

4. Provide system password and press Enter

5. In Terminal, type command below and press Enter

    cd /Users/me/Developer/MyAudioApp

6. Create project pod file - in Terminal type command below and press Enter

    touch Podfile

7. Open project pod file - in Terminal type command below and press Enter (opens in TextEdit)

    open Podfile

8. Edit code below into open pod file (and save file before quitting TextEdit)

    source 'https://github.com/CocoaPods/Specs.git'
        platform :ios, '12.2'
        use_frameworks!

        target 'MyAudioApp' do
        pod 'AudioKit', '~> 4.7'
    end

9. To install AudioKit in MyAudioApp workspace type Terminal command below and press Enter

    Pod install     

and wait for install to finish

10. In Finder, go to project folder /Users/me/Developer/MyAudioApp and click .xcworkspace file below (opens in Xcode!)

    /Users/me/Developer/MyAudioApp/MyAudioApp.xcworkspace

11. In MyAudioApp edit ViewController.swift and insert the following

    import AudioKit 

Scaling both is hard in a distributed fault tolerant way but I'd make a case that it's much harder at massive scale with RabbitMQ. It's not trivial to understand Shovel, Federation, Mirrored Msg Queues, ACK, Mem issues, Fault tollerance etc. Not to say you won't also have specific issues with Zookeeper etc on Kafka but there are less moving parts to manage. That said, you get a Polyglot exchange with RMQ which you don't with Kafka. If you want streaming, use Kafka. If you want simple IoT or similar high volume packet delivery, use Kafka. It's about smart consumers. If you want msg flexibility and higher reliability with higher costs and possibly some complexity, use RMQ.

To make use of regular expressions directly in Excel formulas the following UDF (user defined function) can be of help. It more or less directly exposes regular expression functionality as an excel function.

How it works

It takes 2-3 parameters.

1. A text to use the regular expression on.
2. A regular expression.
3. A format string specifying how the result should look. It can contain $0, $1, $2, and so on. $0 is the entire match, $1 and up correspond to the respective match groups in the regular expression. Defaults to $0.

Some examples

Extracting an email address:

=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+")
=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+", "$0")

Results in: [email protected]

Extracting several substrings:

=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "E-Mail: $2, Name: $1")

Results in: E-Mail: [email protected], Name: Peter Gordon

To take apart a combined string in a single cell into its components in multiple cells:

=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "$" & 1)
=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "$" & 2)

Results in: Peter Gordon [email protected] ...

How to use

To use this UDF do the following (roughly based on this Microsoft page. They have some good additional info there!):

1. In Excel in a Macro enabled file ('.xlsm') push ALT+F11 to open the Microsoft Visual Basic for Applications Editor.
2. Add VBA reference to the Regular Expressions library (shamelessly copied from Portland Runners++ answer):
   1. Click on Tools -> References (please excuse the german screenshot)
   2. Find Microsoft VBScript Regular Expressions 5.5 in the list and tick the checkbox next to it.
   3. Click OK.

3. Click on Insert Module. If you give your module a different name make sure the Module does not have the same name as the UDF below (e.g. naming the Module Regex and the function regex causes #NAME! errors).

   

4. In the big text window in the middle insert the following:

   Function regex(strInput As String, matchPattern As String, Optional ByVal outputPattern As String = "$0") As Variant
       Dim inputRegexObj As New VBScript_RegExp_55.RegExp, outputRegexObj As New VBScript_RegExp_55.RegExp, outReplaceRegexObj As New VBScript_RegExp_55.RegExp
       Dim inputMatches As Object, replaceMatches As Object, replaceMatch As Object
       Dim replaceNumber As Integer
   
       With inputRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .Pattern = matchPattern
       End With
       With outputRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .Pattern = "\$(\d+)"
       End With
       With outReplaceRegexObj
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
       End With
   
       Set inputMatches = inputRegexObj.Execute(strInput)
       If inputMatches.Count = 0 Then
           regex = False
       Else
           Set replaceMatches = outputRegexObj.Execute(outputPattern)
           For Each replaceMatch In replaceMatches
               replaceNumber = replaceMatch.SubMatches(0)
               outReplaceRegexObj.Pattern = "\$" & replaceNumber
   
               If replaceNumber = 0 Then
                   outputPattern = outReplaceRegexObj.Replace(outputPattern, inputMatches(0).Value)
               Else
                   If replaceNumber > inputMatches(0).SubMatches.Count Then
                       'regex = "A to high $ tag found. Largest allowed is $" & inputMatches(0).SubMatches.Count & "."
                       regex = CVErr(xlErrValue)
                       Exit Function
                   Else
                       outputPattern = outReplaceRegexObj.Replace(outputPattern, inputMatches(0).SubMatches(replaceNumber - 1))
                   End If
               End If
           Next
           regex = outputPattern
       End If
   End Function
   

5. Save and close the Microsoft Visual Basic for Applications Editor window.

This is a good one:

           num = (-1521134295 * num) + key1;
           num += (num << 10);
           num ^= (num >> 6);

           num = ((-1521134295 * num) + key2);
           num += (num << 10);
           num ^= (num >> 6);

           return num;
        }
    }

    public static int GetHashCode(params object[] arr)
    {
        int hash = 0;
        foreach (var item in arr)
            hash = GetHashCodeInternal(hash, item.GetHashCode());
        return hash;
    }

    }

    {
        return GetHashCodeInternal(obj1.GetHashCode(), obj2.GetHashCode());
    }
}

And here is how to use it:

private struct Key
{
    private Type _type;
    private string _field;

    public Type Type { get { return _type; } }
    public string Field { get { return _field; } }

    public Key(Type type, string field)
    {
        _type = type;
        _field = field;
    }

    public override int GetHashCode()
    {
        return HashCodeHelper.GetHashCode(_field, _type);
    }

    public override bool Equals(object obj)
    {
        if (!(obj is Key))
            return false;
        var tf = (Key)obj;
        return tf._field.Equals(_field) && tf._type.Equals(_type);
    }
}

Query below should help you achieve what you want.

select scountry, headofstate from data 
where data.scountry like 'a%'and ttlppl>=100000

I tried all of these solutions but this is the one that works every time.

We just change the "Publish method:" from "File System" to for example "Web Deploy", and immediately change it back to "File System".

I just saw this as a result of a network error / time-out on a flaky network. I could see the progress bar increasing after I got the bright idea of just retrying. Also saw HTTP Range requests on the download server with ever increasing offsets of a few megabytes (the entire app was about 44MB).

I was using command line C-compiler to compile these and it completely drove me bonkers as it refused to compile.

For some reason my compiler hated that I was declaring and using the function all in one line.

struct tm tm = *localtime(&t);

test.c
test.c(494) : error C2143: syntax error : missing ';' before 'type'
Compiler Status: 512

First declare your variable and then call the function. This is how I did it.

char   todayDateStr[100];
time_t rawtime;
struct tm *timeinfo;

time ( &rawtime );
timeinfo = localtime ( &rawtime );
strftime(todayDateStr, strlen("DD-MMM-YYYY HH:MM")+1,"%d-%b-%Y %H:%M",timeinfo);
printf("todayDateStr = %s ... \n", todayDateStr );

You could use memset, if you sure about the length.

memset(ptr, 0x00, length)

There's talk about interoperability between C and Go when using the gcc Go compiler, gccgo. There are limitations both to the interoperability and the implemented feature set of Go when using gccgo, however (e.g., limited goroutines, no garbage collection).

The simple command 'keytool' also works on Windows and/or with Cygwin.

IF you're using Cygwin here is the modified command that I used from the bottom of "S.Botha's" answer :

1. make sure you identify the JRE inside the JDK that you will be using
2. Start your prompt/cygwin as admin
3. go inside the bin directory of that JDK e.g. cd /cygdrive/c/Program\ Files/Java/jdk1.8.0_121/jre/bin

4. Execute the keytool command from inside it, where you provide the path to your new Cert at the end, like so:

   ./keytool.exe -import -trustcacerts -keystore ../lib/security/cacerts  -storepass changeit -noprompt -alias myownaliasformysystem -file "D:\Stuff\saved-certs\ca.cert"
   

Notice, because if this is under Cygwin you're giving a path to a non-Cygwin program, so the path is DOS-like and in quotes.

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:

<form action="some.jsp">
  <select name="item">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
  </select>
  <input type="submit" value="Submit">
</form>

in some.jsp

request.getParameter("item");

this line will return the selected option (from the example it is: 1, 2 or 3)

For start Activity 2 from Activity 1 and get result, you could use startActivityForResult and implement onActivityResult in Activity 1 and use setResult in Activity2.

Intent intent = new Intent(this, Activity2.class);
intent.putExtra(NUMERO1, numero1);
intent.putExtra(NUMERO2, numero2);
//startActivity(intent);
startActivityForResult(intent, MI_REQUEST_CODE);

if you have neccessary .net framework installed. Ex ; .Net 4.0 or .Net 3.5, then you can just copy Gacutil.exe from any of the machine and to the new machine.

1) Open CMD as adminstrator in new server.
2) Traverse to the folder where you copied the Gacutil.exe. For eg - C:\program files.(in my case).
3) Type the below in the cmd prompt and install.

C:\Program Files\gacutil.exe /I dllname

I don't mean this to sound snarky, but it doesn't matter.

Seriously.

Look at the things that are important: your project, your code, your job, your personal life. None of them are going to have their success rest on whether or not you use the "this" keyword to qualify access to fields. The this keyword will not help you ship on time. It's not going to reduce bugs, it's not going to have any appreciable effect on code quality or maintainability. It's not going to get you a raise, or allow you to spend less time at the office.

It's really just a style issue. If you like "this", then use it. If you don't, then don't. If you need it to get correct semantics then use it. The truth is, every programmer has his own unique programing style. That style reflects that particular programmer's notions of what the "most aesthetically pleasing code" should look like. By definition, any other programmer who reads your code is going to have a different programing style. That means there is always going to be something you did that the other guy doesn't like, or would have done differently. At some point some guy is going to read your code and grumble about something.

I wouldn't fret over it. I would just make sure the code is as aesthetically pleasing as possible according to your own tastes. If you ask 10 programmers how to format code, you are going to get about 15 different opinions. A better thing to focus on is how the code is factored. Are things abstracted right? Did I pick meaningful names for things? Is there a lot of code duplication? Are there ways I can simplify stuff? Getting those things right, I think, will have the greatest positive impact on your project, your code, your job, and your life. Coincidentally, it will probably also cause the other guy to grumble the least. If your code works, is easy to read, and is well factored, the other guy isn't going to be scrutinizing how you initialize fields. He's just going to use your code, marvel at it's greatness, and then move on to something else.

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

When you use conda managing your python envs, follow these two steps:

1. activate py3 (on Windows or source activate py3 on Linux)
2. conda install notebook ipykernel or just use conda install jupyter

            writer.write(buffer, 0, n);
        }
    } finally {
        is.close();
    }

    String text = writer.toString();
    return text;

When you pass a pointer by a non-const reference, you are telling the compiler that you are going to modify that pointer's value. Your code does not do that, but the compiler thinks that it does, or plans to do it in the future.

To fix this error, either declare x constant

// This tells the compiler that you are not planning to modify the pointer
// passed by reference
void test(float * const &x){
    *x = 1000;
}

or make a variable to which you assign a pointer to nKByte before calling test:

float nKByte = 100.0;
// If "test()" decides to modify `x`, the modification will be reflected in nKBytePtr
float *nKBytePtr = &nKByte;
test(nKBytePtr);

It's been a long time since I've worked in a Windows environment, but I would suggest that you look at using WMI.

When you're going to work with such time series in Python, pandas is indispensable. And here's the good news: it comes with a historical data downloader for Yahoo: pandas.io.data.DataReader.

from pandas.io.data import DataReader
from datetime import datetime

ibm = DataReader('IBM',  'yahoo', datetime(2000, 1, 1), datetime(2012, 1, 1))
print(ibm['Adj Close'])

Here's an example from the pandas documentation.

Update for pandas >= 0.19:

The pandas.io.data module has been removed from pandas>=0.19 onwards. Instead, you should use the separate pandas-datareader package. Install with:

pip install pandas-datareader

And then you can do this in Python:

import pandas_datareader as pdr
from datetime import datetime

ibm = pdr.get_data_yahoo(symbols='IBM', start=datetime(2000, 1, 1), end=datetime(2012, 1, 1))
print(ibm['Adj Close'])

Downloading from Google Finance is also supported.

There's more in the documentation of pandas-datareader.

If you use RecycleView, first you need more efford to setup. You need to give more time to setup simple Item onclick, border, touch event and other simple thing. But end product will be perfect.

So decision is yours. I suggest, if you design simple app like phonebook loading, where simple click of item is enough, you can implement listview. But if you design like social media home page with unlimited scrolling. Several different decoration between item, much control of individual item than use recycle view.

Generating locales

Missing locales are generated with locale-gen:

locale-gen en_US.UTF-8

Alternatively a locale file can be created manually with localedef:[1]

localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings

The locale settings can be set (to en_US.UTF-8 in the example) as follows:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

dpkg-reconfigure locales

The dpkg-reconfigure locales command will open a dialog under Debian for selecting the desired locale. This dialog will not appear under Ubuntu. The Configure Locales in Ubuntu article shows how to find the information regarding Ubuntu.

We all know that programming have endless possibilities.There are numbers of solutions available for a single problem so i think all of the above solutions are perfect and may be helpful for someone but for me this one save my day..

So Code goes like this

  private void getWebsite() {
    new Thread(new Runnable() {
      @Override
      public void run() {
        final StringBuilder builder = new StringBuilder();

        try {
          Document doc = Jsoup.connect("http://www.ssaurel.com/blog").get();
          String title = doc.title();
          Elements links = doc.select("a[href]");

          builder.append(title).append("\n");

          for (Element link : links) {
            builder.append("\n").append("Link : ").append(link.attr("href"))
            .append("\n").append("Text : ").append(link.text());
          }
        } catch (IOException e) {
          builder.append("Error : ").append(e.getMessage()).append("\n");
        }

        runOnUiThread(new Runnable() {
          @Override
          public void run() {
            result.setText(builder.toString());
          }
        });
      }
    }).start();
  }

You just have to call the above function in onCreate Method of your MainActivity

I hope this one is also helpful for you guys.

Also read the original blog at Medium

Add to top of the code,

#!/usr/bin/python

Then, run the following command on the terminal,

chmod +x yourScriptFile

Funny you mention that, I did a blog post on this very subject.

See Oracle vs MySQL vs SQL Server: Aggregation vs Joins

Short answer: you have to test it and individual databases vary a lot.

Check if you imported the header files of classes that are throwing this error.

Here you go:

public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
    return encoding.GetBytes(str);
}

public static String ToBinary(Byte[] data)
{
    return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}

// Use any sort of encoding you like. 
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));

1. After closing the Conflict Error Dialog; from the Project Explorer, right click on the head of the project -> Team -> Stashes -> Stash Changes
2. Enter a name for your stash. E.G. "Conflict"
3. Try Pulling again. Hopefully there are no errors this time.
4. From the Git Repository view, expand your repository -> Stashed Commits
5. Right Click on the stash you created in step 2 -> Apply Stashed Changes
6. This brings up the merge tool if it can't automatically merge it.
7. Manually resolve the merge conflicts in the file/s.
8. Right Click on the file editor -> Team -> Add To Index
9. If you are not ready to commit the file or just don't want it in the Index, right click on the file editor -> Team -> Remove from Index.
10. Cleanup: From the Git Repository view, right Click on the stash you created in step 2 -> Delete Stashed Commit

Your local working directory file should be be merged

Use the 'And' keyword for a logical and. Like this:

If Not ((filename = testFileName) And (fileName <> "")) Then

FWIW, this config worked for me:

location = /logpush.html {
  if ($request_method = POST) {
    access_log /var/log/nginx/push.log push_requests;
    proxy_pass $scheme://127.0.0.1/logsink;
    break;
  }   
  return 200 $scheme://$host/serviceup.html;
}   
#
location /logsink {
  return 200;
}

Here is another one, I think. Just for reference. Let's set a variable to be an instantance of class StringVar

If you program Tk using the Tcl language, you can ask the system to let you know when a variable is changed. The Tk toolkit can use this feature, called tracing, to update certain widgets when an associated variable is modified.

There’s no way to track changes to Python variables, but Tkinter allows you to create variable wrappers that can be used wherever Tk can use a traced Tcl variable.

text = StringVar()
self.depositLabel = Label(self.__mainWindow, text = self.labelText, textvariable = text)
                                                                    ^^^^^^^^^^^^^^^^^
  def depositCallBack(self,event):
      text.set('change the value')

As shell command:

< /dev/zero head -c 1048576 >  output

I used this library called Parser. It worked for what I needed.

import React, { Component } from 'react';    
import Parser from 'html-react-parser';

class MyComponent extends Component {
  render() {
    <div>{Parser(this.state.message)}</div>
  }
};

You could do something like the following:

static int tableWidth = 73;

static void Main(string[] args)
{
    Console.Clear();
    PrintLine();
    PrintRow("Column 1", "Column 2", "Column 3", "Column 4");
    PrintLine();
    PrintRow("", "", "", "");
    PrintRow("", "", "", "");
    PrintLine();
    Console.ReadLine();
}

static void PrintLine()
{
    Console.WriteLine(new string('-', tableWidth));
}

static void PrintRow(params string[] columns)
{
    int width = (tableWidth - columns.Length) / columns.Length;
    string row = "|";

    foreach (string column in columns)
    {
        row += AlignCentre(column, width) + "|";
    }

    Console.WriteLine(row);
}

static string AlignCentre(string text, int width)
{
    text = text.Length > width ? text.Substring(0, width - 3) + "..." : text;

    if (string.IsNullOrEmpty(text))
    {
        return new string(' ', width);
    }
    else
    {
        return text.PadRight(width - (width - text.Length) / 2).PadLeft(width);
    }
}

Another easy solution to disable swiping at specific page (in this example, page 2):

int PAGE = 2;
viewPager.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
        if (viewPager.getCurrentItem() == PAGE) {
                viewPager.setCurrentItem(PAGE-1, false);
                viewPager.setCurrentItem(PAGE, false);
                return  true;
        }
        return false;
}

Turing-completeness is not only about "defining functions" or "have ifs/loops/etc". For example, Haskell doesn't have "loop", lambda-calculus don't have "ifs", etc...

For example, this site: http://experthuman.com/programming-with-nothing. The author uses Ruby and create a "FizzBuzz" program with only closures (no strings, numbers, or anything like that)...

There are examples when people compute some arithmetical functions on Scala using only the type system

So, yes, in my opinion, CSS3+HTML is turing-complete (even if you can't exactly do any real computation with then without becoming crazy)

there are several ways. You can use this method:

start = @selected_date.beginning_of_day
end = @selected_date.end_of_day
@comments = Comment.where("DATE(created_at) BETWEEN ? AND ?", start, end)

Or this:

@comments = Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day)

If you have just one Read-Request

Combine the answer of @redsio with a temp-table (600K is not that much):

DROP TEMPORARY TABLE IF EXISTS tmp_randorder;
CREATE TABLE tmp_randorder (id int(11) not null auto_increment primary key, data_id int(11));
INSERT INTO tmp_randorder (data_id) select id from datatable;

And then take a version of @redsios Answer:

SELECT dt.*
FROM
       (SELECT (RAND() *
                     (SELECT MAX(id)
                        FROM tmp_randorder)) AS id)
        AS rnd
 INNER JOIN tmp_randorder rndo on rndo.id between rnd.id - 10 and rnd.id + 10
 INNER JOIN datatable AS dt on dt.id = rndo.data_id
 ORDER BY abs(rndo.id - rnd.id)
 LIMIT 1;

If the table is big, you can sieve on the first part:

INSERT INTO tmp_randorder (data_id) select id from datatable where rand() < 0.01;

If you have many read-requests

1. Version: You could keep the table tmp_randorder persistent, call it datatable_idlist. Recreate that table in certain intervals (day, hour), since it also will get holes. If your table gets really big, you could also refill holes

   select l.data_id as whole from datatable_idlist l left join datatable dt on dt.id = l.data_id where dt.id is null;

2. Version: Give your Dataset a random_sortorder column either directly in datatable or in a persistent extra table datatable_sortorder. Index that column. Generate a Random-Value in your Application (I'll call it $rand).

   select l.*
   from datatable l 
   order by abs(random_sortorder - $rand) desc 
   limit 1;
   

This solution discriminates the 'edge rows' with the highest and the lowest random_sortorder, so rearrange them in intervals (once a day).

Open the SVG with you text editor. If you have some luck the file will contain something like:

The d attribute is what you are looking for.

Look for native_transport_port in /etc/cassandra/cassandra.yaml The default is 9842.

native_transport_port: 9842

For connecting to localhost with cqlsh, this port worked for me.

cqlsh 127.0.0.1 9842

Used to face the same problem. The reason was in incorrect context passing to AlertDialog.Builder(here). use like AlertDialog.Builder(Homeactivity.this)

This goes to you model:

public function count_news_by_category($cat)
{
    return $this->db
        ->where('category', $cat)
        ->where('is_enabled', 1)
        ->count_all_results('news');
}

It'a an example from my current project.

According to benchmarking this query works faster than if you do the following:

$this->db->select('*')->from('news')->where(...); 
$q = $this->db->get(); 
return $q->num_rows();

Background images sure can present data! In fact, this is often recommended where presenting visual icons is more compact and user-friendly than an equivalent list of text blurbs. Any use of image sprites can benefit from this approach.

It is quite common for hotel listings icons to display amenities. Imagine a page which listed 50 hotel and each hotel had 10 amenities. A CSS Sprite would be perfect for this sort of thing -- better user experience because it's faster. But how do you implement ALT tags for these images? Example site.

The answer is that they don't use alt text at all, but instead use the title attribute on the containing div.

HTML

<div class="hotwire-fitness" title="Fitness Centre"></div>

CSS

.hotwire-fitness {
    float: left;
    margin-right: 5px;
    background: url(/prostyle/images/new_amenities.png) -71px 0;
    width: 21px;
    height: 21px;
}

According to the W3C (see links above), the title attribute serves much of the same purpose as the alt attribute

Title

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a "tool tip" (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context. For example, setting the attribute on a link allows user agents (visual and non-visual) to tell users about the nature of the linked resource:

alt

The alt attribute is defined in a set of tags (namely, img, area and optionally for input and applet) to allow you to provide a text equivalent for the object.

A text equivalent brings the following benefits to your website and its visitors in the following common situations:

• nowadays, Web browsers are available in a very wide variety of platforms with very different capacities; some cannot display images at all or only a restricted set of type of images; some can be configured to not load images. If your code has the alt attribute set in its images, most of these browsers will display the description you gave instead of the images
• some of your visitors cannot see images, be they blind, color-blind, low-sighted; the alt attribute is of great help for those people that can rely on it to have a good idea of what's on your page
• search engine bots belong to the two above categories: if you want your website to be indexed as well as it deserves, use the alt attribute to make sure that they won't miss important sections of your pages.

One trick I found helpful for large data use cases is to reduce the volume of the data by reducing float precision to 32-bit. It's not applicable in all cases, but in many applications 64-bit precision is overkill and the 2x memory savings are worth it. To make an obvious point even more obvious:

>>> df = pd.DataFrame(np.random.randn(int(1e8), 5))
>>> df.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 100000000 entries, 0 to 99999999
Data columns (total 5 columns):
...
dtypes: float64(5)
memory usage: 3.7 GB

>>> df.astype(np.float32).info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 100000000 entries, 0 to 99999999
Data columns (total 5 columns):
...
dtypes: float32(5)
memory usage: 1.9 GB

You can use Visual Studio for C, but if you are serious about learning the newest C available, I recommend using something like Code::Blocks with MinGW-TDM version, which you can get a 32 bit version of. I use version 5.1 which supports the newest C and C++. Another benefit is that it is a better platform for creating software that can be easily ported to other platforms. If you were, for example, to code in C, using the SDL library, you could create software that could be recompiled with little to no changes to the code, on Linux, Apple and many mobile devices. The way Microsoft has been going these days, I think this is definitely the better route to take.

To add 10px separation between each section just write this

flowLayout.sectionInset = UIEdgeInsetsMake(0.0, 0.0,10,0);

From JavaDoc:

• A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.
• next(): Finds and returns the next complete token from this scanner.
• nextLine(): Advances this scanner past the current line and returns the input that was skipped.

So in case of "small example<eol>text" next() should return "small" and nextLine() should return "small example"

In the terminal just enter the traditional command:

mongod --version

From what suggest others and from pathlib documentation, a simple and clear solution is the following (suppose the file we need to refer to: Test/data/users.csv:

# This file location: Tests/src/long/module/subdir/some_script.py
from pathlib import Path

# back to Tests/
PROJECT_ROOT = Path(__file__).parents[4]
# then down to Test/data/users.csv
CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'  

with CSV_USERS_PATH.open() as users:
    print(users.read())

Now this looks a bit odd to me, because if you move some_script.py around, the path to the root of our project may change (we would need to modify parents[4]). On the other hand I found a solution that I prefer based on the same idea.

Suppose we have the following directory structure:

Tests
+-- data
¦  +-- users.csv
+-- src
   +-- long
   ¦  +-- module
   ¦     +-- subdir
   ¦        +-- some_script.py
   +-- main.py
   +-- paths.py

The paths.py file will be responsible for storing the root location of our projet:

from pathlib import Path

PROJECT_ROOT = Path(__file__).parents[1]

All scripts can now use paths.PROJECT_ROOT to express absolute paths from the root of the project. For example in src/long/module/subdir/some_script.py we could have:

from paths import PROJECT_ROOT

CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'

def hello():
    with CSV_USERS_PATH.open() as f:
        print(f.read())

And everything goes as expected:

~/Tests/src/$ python main.py

/Users/cglacet/Tests/data/users.csv
hello, user

~/Tests/$ python src/main.py

/Users/cglacet/Tests/data/users.csv
hello, user

The main.py script simply is:

from long.module.subdir import some_script

some_script.hello()

There is nothing to fix. You simply have made 3 commits and haven't moved them to the remote branch yet. There are several options, depending on what you want to do:

• git push: move your changes to the remote (this might get rejected if there are already other changes on the remote)
• do nothing and keep coding, sync another day
• git pull: get the changes (if any) from the remote and merge them into your changes
• git pull --rebase: as above, but try to redo your commits on top of the remote changes

You are in a classical situation (although usually you wouldn't commit a lot on master in most workflows). Here is what I would normally do: Review my changes. Maybe do a git rebase --interactive to do some cosmetics on them, drop the ones that suck, reorder them to make them more logical. Now move them to the remote with git push. If this gets rejected because my local branch is not up to date: git pull --rebase to redo my work on top of the most recent changes and git push again.

def dbz():
    try:

            d = int(r)/i

            print "Not a number"
    except Exception ,e:
        print "Program halted incorrect data entered",type(e)

1. delete your project folder under C:\....\wildfly-9.0.1.Final\standalone\deployments\YOUR-PROJEKT-FOLDER
2. restart your wildfly-server

It sounds like you want to convert the rownames to a proper column of the data.frame. eg:

# add the rownames as a proper column
myDF <- cbind(Row.Names = rownames(myDF), myDF)
myDF

#           Row.Names id val vr2
# row_one     row_one  A   1  23
# row_two     row_two  A   2  24
# row_three row_three  B   3  25
# row_four   row_four  C   4  26

If you want to then remove the original rownames:

rownames(myDF) <- NULL
myDF
#   Row.Names id val vr2
# 1   row_one  A   1  23
# 2   row_two  A   2  24
# 3 row_three  B   3  25
# 4  row_four  C   4  26

Alternatively, if all of your data is of the same class (ie, all numeric, or all string), you can convert to Matrix and name the dimnames

myMat <- as.matrix(myDF)
names(dimnames(myMat)) <- c("Names.of.Rows", "")
myMat

# Names.of.Rows id  val vr2 
#   row_one   "A" "1" "23"
#   row_two   "A" "2" "24"
#   row_three "B" "3" "25"
#   row_four  "C" "4" "26"

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

Here is a different method same thing but a little different

the difference is the content dot which is replaced with a \00A0 == whitespace

More on this http://www.jqui.net/tips-tricks/css-clearfix/

.clearfix:after { content: "\00A0"; display: block; clear: both; visibility: hidden; line-height: 0; height: 0;}
.clearfix{ display: inline-block;}
html[xmlns] .clearfix { display: block;}
* html .clearfix{ height: 1%;}
.clearfix {display: block}

Here is a compact version of it...

.clearfix:after { content: "\00A0"; display: block; clear: both; visibility: hidden; line-height: 0; height: 0;width:0;font-size: 0px}.clearfix{ display: inline-block;}html[xmlns] .clearfix { display: block;}* html .clearfix{ height: 1%;}.clearfix {display: block}

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID
----
1
2
4

SELECT DISTINCT 
   o.name AS Object_Name,
   o.type_desc
FROM sys.sql_modules m        INNER JOIN        sys.objects o 
     ON m.object_id = o.object_id WHERE m.definition Like '%[String]%';

We can use arrayUnion({}) method to achive this.

Try this:

collectionRef.doc(ID).update({
    sharedWith: admin.firestore.FieldValue.arrayUnion({
       who: "[email protected]",
       when: new Date()
    })
});

The official link no longer offers the original source code. The official link and casual google searches will land you with open jdk. Open jdk causes problems with android build unless the build script files are modified. The original package can be found here:

Another option - start a debugger where the test fails.

Try running your tests with Testoob (it will run your unittest suite without changes), and you can use the '--debug' command line switch to open a debugger when a test fails.

Here's a terminal session on windows:

C:\work> testoob tests.py --debug
F
Debugging for failure in test: test_foo (tests.MyTests.test_foo)
> c:\python25\lib\unittest.py(334)failUnlessEqual()
-> (msg or '%r != %r' % (first, second))
(Pdb) up
> c:\work\tests.py(6)test_foo()
-> self.assertEqual(x, y)
(Pdb) l
  1     from unittest import TestCase
  2     class MyTests(TestCase):
  3       def test_foo(self):
  4         x = 1
  5         y = 2
  6  ->     self.assertEqual(x, y)
[EOF]
(Pdb)

It might be a bit hacky. You can try this.

if (JSON.stringify(data).length === 2) {
   // Do something
}

Not sure if there is any disadvantage of this method.

In SQL Server 2008 you can use a multi-table update as follows:

UPDATE tblindiantime 
SET tblindiantime.CountryName = contacts.BusinessCountry
FROM tblindiantime 
JOIN contacts
ON -- join condition here

You need a join condition to specify which row should be updated.

If the target table is currently empty then you should use an INSERT instead:

INSERT INTO tblindiantime (CountryName)
SELECT BusinessCountry FROM contacts

import itertools
a = [['a','b'], ['c']]
print(list(itertools.chain.from_iterable(a)))

check this as well This gives an overview of associated constraints across a database. Please also include facilitating where condition with table name of interest so gives information faster.

   select 
a.TABLE_CATALOG as DB_name,a.TABLE_SCHEMA as tbl_schema, a.TABLE_NAME as tbl_name,a. CONSTRAINT_NAME as constraint_name,b.CONSTRAINT_TYPE
 from INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE a
join INFORMATION_SCHEMA.TABLE_CONSTRAINTS b on
 a.CONSTRAINT_NAME=b.CONSTRAINT_NAME

This makes sure you are getting the latest version from of the css or js file from the server.

And later you can append "?v=2" if you have a newer version and "?v=3", "?v=4" and so on.

Note that you can use any querystring, 'v' is not a must for example:

"?blah=1" will work as well.

And

"?xyz=1002" will work.

And this is a common technique because browsers are now caching js and css files better and longer.

Including "string.h" makes things easier. An easier way to tackle your problem is:

#include <string.h>
    char* createStr(){
    static char str[20] = "my";
    return str;
}
int main(){
    char a[20];
    strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
    printf("%s",a);
    return 0;
}

I don't think using document.write is a bad practice at all. In simple words it is like a high voltage for inexperienced people. If you use it the wrong way, you get cooked. There are many developers who have used this and other dangerous methods at least once, and they never really dig into their failures. Instead, when something goes wrong, they just bail out, and use something safer. Those are the ones who make such statements about what is considered a "Bad Practice".

It's like formatting a hard drive, when you need to delete only a few files and then saying "formatting drive is a bad practice".

(Sorry, can't add comments)

In Blaise's answer above, if you change:

@XmlJavaTypeAdapter(MapAdapter.class)
public Map<String, String> getMapProperty() {
    return mapProperty;
}

to:

@XmlJavaTypeAdapter(MapAdapter.class)
@XmlPath(".") // <<-- add this
public Map<String, String> getMapProperty() {
    return mapProperty;
}

then this should get rid of the <mapProperty> tag, and so give you:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <map>
        <key>value</key>
        <key2>value2</key2>
    </map>
</root>

ALTERNATIVELY:

You can also change it to:

@XmlJavaTypeAdapter(MapAdapter.class)
@XmlAnyElement // <<-- add this
public Map<String, String> getMapProperty() {
    return mapProperty;
}

and then you can get rid of AdaptedMap altogether, and just change MapAdapter to marshall to a Document object directly. I've only tested this with marshalling, so there may be unmarshalling issues.

I'll try and find the time to knock up a full example of this, and edit this post accordingly.

If ( You know Java ) {

Python code is converted into bytecode like java does.
That bytecode is executed again everytime you try to access it.

} else {

Python code is initially traslated into something called bytecode
that is quite close to machine language but not actual machine code
so each time we access or run it that bytecode is executed again

}

This isn’t a solution in the sense that it doesn’t resolve the conditions which cause the message to appear in the logs, but the message can be suppressed by appending the following to conf/logging.properties:

org.apache.catalina.webresources.Cache.level = SEVERE

This filters out the “Unable to add the resource” logs, which are at level WARNING.

In my view a WARNING is not necessarily an error that needs to be addressed, but rather can be ignored if desired.

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

To send a file from windows to linux system

scp path-to-file user@ipaddress:/path-to-destination

Example:

scp C:/Users/adarsh/Desktop/Document.txt [email protected]:/tmp

keep in mind that there need to use forward slash(/) inplace of backward slash(\) in for the file in windows path else it will show an error

C:UsersadarshDesktopDocument.txt: No such file or directory

. After executing scp command you will ask for password of root user in linux machine. There you GO...

To send a file from linux to windows system

scp -r user@ipaddress:/path-to-file path-to-destination

Example:

scp -r [email protected]:/tmp/Document.txt C:/Users/adarsh/Desktop/

and provide your linux password. only one you have to add in this command is -r. Thanks.

Login to your SQL server from a terminal

 mysql -u root -p
 -- root password
GRANT ALL ON *.* to root@'XX.XXX.XXX.XX' IDENTIFIED BY 'password';

This should solve the permission issue.

Happy coding!!

The best way to get the current time and date is by the date function in PHP:

$date = date('FORMAT'); // FORMAT E.g.: Y-m-d H:i:s

$current_date = date('Y-m-d H:i:s');

With the Unix timestamp:

$now_date = date('FORMAT', time()); // FORMAT Eg : Y-m-d H:i:s

To set the server time zone:

date_default_timezone_set('Asia/Calcutta');

A different time zone list is here.

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

In a component below <Router>

Just add a React Hook (in case you are not using a React class)

  React.useEffect(() => {
    window.scrollTo(0, 0);
  }, [props.location]);

for activity

findViewById(android.R.id.content).setBackgroundColor(color)

Another way - from an ISO 8601 date.

var timestamp = 1293683278;_x000D_
var date = new Date(timestamp * 1000);_x000D_
var iso = date.toISOString().match(/(\d{2}:\d{2}:\d{2})/)_x000D_
alert(iso[1]);

By far the easiest way to create DOC files on Linux, using PHP is with the Zend Framework component phpLiveDocx.

From the project web site:

"phpLiveDocx allows developers to generate documents by combining structured data from PHP with a template, created in a word processor. The resulting document can be saved as a PDF, DOCX, DOC or RTF file. The concept is the same as with mail-merge."

reloadRowsAtIndexPaths: is fine, but still will force UITableViewDelegate methods to fire.

The simplest approach I can imagine is:

UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:indexPath];
[self configureCell:cell forIndexPath:indexPath];

It's important to invoke your configureCell: implementation on main thread, as it wont work on non-UI thread (the same story with reloadData/reloadRowsAtIndexPaths:). Sometimes it might be helpful to add:

dispatch_async(dispatch_get_main_queue(), ^
{
    [self configureCell:cell forIndexPath:indexPath];
});

It's also worth to avoid work that would be done outside of the currently visible view:

BOOL cellIsVisible = [[self.tableView indexPathsForVisibleRows] indexOfObject:indexPath] != NSNotFound;
if (cellIsVisible)
{
    ....
}

Functional Interface:

• Introduced in Java 8
• Interface that contains a "single abstract" method.

Example 1:

   interface CalcArea {   // --functional interface
        double calcArea(double rad);
    }           

Example 2:

interface CalcGeometry { // --functional interface
    double calcArea(double rad);
    default double calcPeri(double rad) {
        return 0.0;
    }
}       

Example 3:

interface CalcGeometry {  // -- not functional interface
    double calcArea(double rad);
    double calcPeri(double rad);
}   

Java8 annotation -- @FunctionalInterface

• Annotation check that interface contains only one abstract method. If not, raise error.
• Even though @FunctionalInterface missing, it is still functional interface (if having single abstract method). The annotation helps avoid mistakes.
• Functional interface may have additional static & default methods.
• e.g. Iterable<>, Comparable<>, Comparator<>.

Applications of Functional Interface:

• Method references
• Lambda Expression
• Constructor references

To learn functional interfaces, learn first default methods in interface, and after learning functional interface, it will be easy to you to understand method reference and lambda expression

In c, this is how you might do it, O(N) and only using O(1) data structures (i.e. a char).

#include<stdio.h>
#include<stdlib.h>
main(){
  char* a = malloc(1000);
  fscanf(stdin, "%[^\0\n]", a);
  int x = 0, y;
  while(a[x]!='\0')
  {
    if (a[x]==' ' || a[x]=='\n')
    {
      x++;
    }
    else
    {
      y=x;
      while(a[y]!='\0' && a[y]!=' ' && a[y]!='\n')
      { 
        y++;
      }
      int z=y;
      while(x<y)
      {
        y--;
        char c=a[x];a[x]=a[y];a[y]=c; 
        x++;
      }
      x=z;
    }
  }

  fprintf(stdout,a);
  return 0;
}

This is the way I am using at this moment... it's very complicated but at least it handles all the possible situations. In case anyone is interested.

public final class MyFragment extends Fragment {
    private TextView vstup;
    private Bundle savedState = null;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.whatever, null);
        vstup = (TextView)v.findViewById(R.id.whatever);

        /* (...) */

        /* If the Fragment was destroyed inbetween (screen rotation), we need to recover the savedState first */
        /* However, if it was not, it stays in the instance from the last onDestroyView() and we don't want to overwrite it */
        if(savedInstanceState != null && savedState == null) {
            savedState = savedInstanceState.getBundle(App.STAV);
        }
        if(savedState != null) {
            vstup.setText(savedState.getCharSequence(App.VSTUP));
        }
        savedState = null;

        return v;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        savedState = saveState(); /* vstup defined here for sure */
        vstup = null;
    }

    private Bundle saveState() { /* called either from onDestroyView() or onSaveInstanceState() */
        Bundle state = new Bundle();
        state.putCharSequence(App.VSTUP, vstup.getText());
        return state;
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        /* If onDestroyView() is called first, we can use the previously savedState but we can't call saveState() anymore */
        /* If onSaveInstanceState() is called first, we don't have savedState, so we need to call saveState() */
        /* => (?:) operator inevitable! */
        outState.putBundle(App.STAV, (savedState != null) ? savedState : saveState());
    }

    /* (...) */

}

Alternatively, it is always a possibility to keep the data displayed in passive Views in variables and using the Views only for displaying them, keeping the two things in sync. I don't consider the last part very clean, though.

Wanted to post this as a comment as a side note to the accepted answer, but that got a bit unclear. So purely as a side note:

If you have no need for the objects themselves and you want to have your project clear of further unused classes, you can parse with something like:

var list = JObject.Parse(json)["People"].Select(el => new { FirstName = (string)el["FirstName"], LastName = (string)el["LastName"] }).ToList();

var firstNames = list.Select(p => p.FirstName).ToList();
var lastNames = list.Select(p => p.LastName).ToList();

Even when using a strongly typed person class, you can still skip the root object by creating a list with JObject.Parse(json)["People"].ToObject<List<Person>>() Of course, if you do need to reuse the objects, it's better to create them from the start. Just wanted to point out the alternative ;)

I'd recommend serialization,

public class Person
{
      public  string FirstName;
      public  string MI;
      public  string LastName;
}

static void Serialize()
{
      clsPerson p = new Person();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";
      System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());
      x.Serialize(System.Console.Out, p);
      System.Console.WriteLine();
      System.Console.WriteLine(" --- Press any key to continue --- ");
      System.Console.ReadKey();
}

You can further control serialization with attributes.
But if it is simple, you could use XmlDocument:

using System;
using System.Xml;

public class GenerateXml {
    private static void Main() {
        XmlDocument doc = new XmlDocument();
        XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
        doc.AppendChild(docNode);

        XmlNode productsNode = doc.CreateElement("products");
        doc.AppendChild(productsNode);

        XmlNode productNode = doc.CreateElement("product");
        XmlAttribute productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "01";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);

        XmlNode nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("Java"));
        productNode.AppendChild(nameNode);
        XmlNode priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        // Create and add another product node.
        productNode = doc.CreateElement("product");
        productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "02";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);
        nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("C#"));
        productNode.AppendChild(nameNode);
        priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        doc.Save(Console.Out);
    }
}

And if it needs to be fast, use XmlWriter:

public static void WriteXML()
{
    // Create an XmlWriterSettings object with the correct options.
    System.Xml.XmlWriterSettings settings = new System.Xml.XmlWriterSettings();
    settings.Indent = true;
    settings.IndentChars = "    "; //  "\t";
    settings.OmitXmlDeclaration = false;
    settings.Encoding = System.Text.Encoding.UTF8;

    using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create("data.xml", settings))
    {

        writer.WriteStartDocument();
        writer.WriteStartElement("books");

        for (int i = 0; i < 100; ++i)
        {
            writer.WriteStartElement("book");
            writer.WriteElementString("item", "Book "+ (i+1).ToString());
            writer.WriteEndElement();
        }

        writer.WriteEndElement();

        writer.Flush();
        writer.Close();
    } // End Using writer 

}

And btw, the fastest way to read XML is XmlReader:

public static void ReadXML()
{
    using (System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"))
    {
        while (xmlReader.Read())
        {
            if ((xmlReader.NodeType == System.Xml.XmlNodeType.Element) && (xmlReader.Name == "Cube"))
            {
                if (xmlReader.HasAttributes)
                    System.Console.WriteLine(xmlReader.GetAttribute("currency") + ": " + xmlReader.GetAttribute("rate"));
            }

        } // Whend 

    } // End Using xmlReader

    System.Console.ReadKey();
}

And the most convenient way to read XML is to just deserialize the XML into a class.
This also works for creating the serialization classes, btw.
You can generate the class from XML with Xml2CSharp:

Try using for Clean XSS

xss_clean($data): "><script>alert(String.fromCharCode(74,111,104,116,111,32,82,111,98,98,105,101))</script>

Not sure about the Java parsing, but that's ISO8601: http://en.wikipedia.org/wiki/ISO_8601

use nth-child(item number) EX

<div class="parent_class">
    <div class="myclass">my text1</div>
    some other code+containers...

    <div class="myclass">my text2</div>
    some other code+containers...

    <div class="myclass">my text3</div>
    some other code+containers...
</div>
.parent_class:nth-child(1) { };
.parent_class:nth-child(2) { };
.parent_class:nth-child(3) { };

OR

:nth-of-type(item number) same your code

.myclass:nth-of-type(1) { };
.myclass:nth-of-type(2) { };
.myclass:nth-of-type(3) { };

Answers of getting all file names recursively with C++11 for Windows and Linux(with experimental/filesystem):
For Windows:

#include <io.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <windows.h>
void getFiles_w(string path, vector<string>& files) {
    intptr_t hFile = 0; 
    struct _finddata_t fileinfo;  
    string p; 
    if ((hFile = _findfirst(p.assign(path).append("\\*").c_str(), &fileinfo)) != -1) {
        do {
            if ((fileinfo.attrib & _A_SUBDIR)) {
                if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0)
                    getFiles(p.assign(path).append("/").append(fileinfo.name), files);
            }
            else {
                files.push_back(p.assign(path).append("/").append(fileinfo.name));
            }
        } while (_findnext(hFile, &fileinfo) == 0);
    }
}

For Linux:

#include <experimental/filesystem>
bool getFiles(std::experimental::filesystem::path path, vector<string>& filenames) {
    namespace stdfs = std::experimental::filesystem;
    // http://en.cppreference.com/w/cpp/experimental/fs/directory_iterator
    const stdfs::directory_iterator end{} ;
    
    for (stdfs::directory_iterator iter{path}; iter != end ; ++iter) {
        // http://en.cppreference.com/w/cpp/experimental/fs/is_regular_file 
        if (!stdfs::is_regular_file(*iter)) { // comment out if all names (names of directories tc.) are required 
            if (getFiles(iter->path(), filenames)) 
                return true;
        }
        else {
            filenames.push_back(iter->path().string()) ;
            cout << iter->path().string() << endl;  
        }
    }
    return false;
}

Just remember to link -lstdc++fs when you compile it with g++ in Linux.

Earlier,I was facing problem in using jquery with React js,so I did following steps to make it working-

1. npm install jquery --save

2. Then, import $ from "jquery";

   See here

BalusC is right. Version 1.0.13 is current, but 1.0.9 appears to have the required bundles:

$ jar tf lib/jfreechart-1.0.9.jar | grep LocalizationBundle.properties 
org/jfree/chart/LocalizationBundle.properties
org/jfree/chart/editor/LocalizationBundle.properties
org/jfree/chart/plot/LocalizationBundle.properties

In the latest and greatest Hibernate, I was able to resolve the dependency by including the hibernate-jpa-2.0-api-1.0.0.Final.jar within lib/jpa directory. I didn't find the ejb-persistence jar in the most recent download.

Create an output file and custom function:

outputFile = open('outputfile.log', 'w')

def printing(text):
    print(text)
    if outputFile:
        outputFile.write(str(text))

Then instead of print(text) in your code, call printing function.

printing("START")
printing(datetime.datetime.now())
printing("COMPLETE")
printing(datetime.datetime.now())

Multiple rows with checkboxes and select all using useState() hooks. Requires minor implementation to adjust to own project.

    const data;

    const [ toggled, setToggled ] = useState(Array.from(new Array(data.length), () => false));
    const [ selected, setSelected ] = useState([]);

    const handleToggleAll = allToggled => {
        let selectAll = !allToggled;
        setAllToggled(selectAll);
        let toggledCopy = [];
        let selectedCopy = [];
        data.forEach(function (e, index) {
            toggledCopy.push(selectAll);
            if(selectAll) {
                selectedCopy.push(index);
            }
        });
        setToggled(toggledCopy);
        setSelected(selectedCopy);
    };

    const handleToggle = index => {

You can simply delete the /var/mail/username file to delete all emails for a specific user. Also, emails that are outgoing but have not yet been sent will be stored in /var/spool/mqueue.

Since no-one mentioned the % operator yet, here comes. It only does truncation, and you cannot rely on the return value not to have floating point inaccuracies, but sometimes it's handy:

scala> 1.23456789 - (1.23456789 % 0.01)
res4: Double = 1.23

I am using Jackson 1.9.7 and I found that doing the following does not solve my serialization/deserialization timezone issue:

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
objectMapper.setDateFormat(dateFormat);

Instead of "2014-02-13T20:09:09.859Z" I get "2014-02-13T08:09:09.859+0000" in the JSON message which is obviously incorrect. I don't have time to step through the Jackson library source code to figure out why this occurs, however I found that if I just specify the Jackson provided ISO8601DateFormat class to the ObjectMapper.setDateFormat method the date is correct.

Except this doesn't put the milliseconds in the format which is what I want so I sub-classed the ISO8601DateFormat class and overrode the format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition) method.

/**
 * Provides a ISO8601 date format implementation that includes milliseconds
 *
 */
public class ISO8601DateFormatWithMillis extends ISO8601DateFormat {

  /**
   * For serialization
   */
  private static final long serialVersionUID = 2672976499021731672L;


  @Override
  public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition)
  {
      String value = ISO8601Utils.format(date, true);
      toAppendTo.append(value);
      return toAppendTo;
  }
}

Try bower install git://github.com/urin/jquery.balloon.js.git#1.0.3 --save where 1.0.3 is the tag number which you can get by reading tag under releases. Also for URL replace by git:// in order for system to connect.

The Problem of auto deintending is caused due to a checkbox being active in the settings of VSCode. Follow these steps:

1. goto preferences

2. goto settings

3. search 'editor:trim auto whitespace'

4. Uncheck The box

Use VIEW. The same classes can be mapped to different tables/views using entity name, so you won't even have much of a duplication. Being there, done that, works OK.

Plain JDBC has another hidden problem: it's unaware of Hibernate session cache, so if something got cached till the end of the transaction and not flushed from Hibernate session, JDBC query won't find it. Could be very puzzling sometimes.

You can also do this by changing .pagination by replacing "text-align: center" with two to three lines of css for left, transform and, depending on circumstances, position.

.pagination {_x000D_
  left: 50%; /* left-align your element to center */_x000D_
  transform: translateX(-50%); /* offset left by half the width of your element */_x000D_
  position: absolute; /* use or dont' use depending on element parent */_x000D_
}_x000D_
.pagination a {_x000D_
  display: block;_x000D_
  width: 30px;_x000D_
  height: 30px;_x000D_
  float: left;_x000D_
  margin-left: 3px;_x000D_
  background: url(/images/structure/pagination-button.png);_x000D_
}_x000D_
.pagination a.last {_x000D_
  width: 90px;_x000D_
  background: url(/images/structure/pagination-button-last.png);_x000D_
}_x000D_
.pagination a.first {_x000D_
  width: 60px;_x000D_
  background: url(/images/structure/pagination-button-first.png);_x000D_
}

<div class='pagination'>_x000D_
  <a class='first' href='#'>First</a>_x000D_
  <a href='#'>1</a>_x000D_
  <a href='#'>2</a>_x000D_
  <a href='#'>3</a>_x000D_
  <a class='last' href='#'>Last</a>_x000D_
</div>_x000D_
<!-- end: .pagination -->

Easy:

print my_queryset.query

For example:

from django.contrib.auth.models import User
print User.objects.filter(last_name__icontains = 'ax').query

It should also be mentioned that if you have DEBUG = True, then all of your queries are logged, and you can get them by accessing connection.queries:

from django.db import connections
connections['default'].queries

The django debug toolbar project uses this to present the queries on a page in a neat manner.

I'm working on an app and face issue of killing my service by on app kill. I researched on google and found that I have to make it foreground. following is the code:

public class UpdateLocationAndPrayerTimes extends Service {

 Context context;
@Override
public void onCreate() {
    super.onCreate();
    context = this;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    StartForground();
    return START_STICKY;
}

@Override
public void onDestroy() {


    super.onDestroy();
}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}


private void StartForground() {
    LocationChangeDetector locationChangeDetector = new LocationChangeDetector(context);
    locationChangeDetector.getLatAndLong();
    Notification notification = new NotificationCompat.Builder(this)
            .setOngoing(false)
            .setSmallIcon(android.R.color.transparent)

            //.setSmallIcon(R.drawable.picture)
            .build();
    startForeground(101,  notification);

    }
}

hops that it may helps!!!!

sort --random-sort $FILE | head -n 1

(I like the shuf approach above even better though - I didn't even know that existed and I would have never found that tool on my own)

NeXTSTEP or NeXTSTEP/Sun depending on who you are asking.

Sun had a fairly large investment in OpenStep for a while. Before Sun entered the picture most things in the foundation, even though it wasn't known as the foundation back then, was prefixed NX, for NeXT, and sometime just before Sun entered the picture everything was renamed to NS. The S most likely did not stand for Sun then but after Sun stepped in the general consensus was that it stood for Sun to honor their involvement.

I actually had a reference for this but I can't find it right now. I will update the post if/when I find it again.

Declare this

[DllImport("user32")]
private static extern bool SetForegroundWindow(IntPtr hwnd);
[DllImport("user32")]
private static extern bool ShowWindowAsync(IntPtr hwnd, int a);

And put this inside your function (note that "checkInstalled" is optional, but if you'll use it, you have to implement it)

if (ckeckInstalled("example"))
{
    int count = Process.GetProcessesByName("example").Count();
    if (count < 1)
        Process.Start("example.exe");
    else
    {
        var proc = Process.GetProcessesByName("example").FirstOrDefault();
        if (proc != null && proc.MainWindowHandle != IntPtr.Zero)
        {
            SetForegroundWindow(proc.MainWindowHandle);
            ShowWindowAsync(proc.MainWindowHandle, 3);
        }
    }
}

NOTE: I'm not sure if this works when more than one instance of the .exe is running.

@PathVariable is used to tell Spring that part of the URI path is a value you want passed to your method. Is this what you want, or are the variables supposed to be form data posted to the URI?

If you want form data, use @RequestParam instead of @PathVariable.

If you want @PathVariable, you need to specify placeholders in the @RequestMapping entry to tell Spring where the path variables fit in the URI. For example, if you want to extract a path variable called contentId, you would use:

@RequestMapping(value = "/whatever/{contentId}", method = RequestMethod.POST)

Edit: Additionally, if your path variable could contain a '.' and you want that part of the data, then you will need to tell Spring to grab everything, not just the stuff before the '.':

@RequestMapping(value = "/whatever/{contentId:.*}", method = RequestMethod.POST)

This is because the default behaviour of Spring is to treat that part of the URL as if it is a file extension, and excludes it from variable extraction.

Run the script every 15 minutes of the hour. For example, you want to receive 15 minute stock price quotes, which are updated every 15 minutes.

while True:
    print("Update data:", datetime.now())
    sleep = 15 - datetime.now().minute % 15
    if sleep == 15:
        run_strategy()
        time.sleep(sleep * 60)
    else:
        time.sleep(sleep * 60)

Unix timestamp is in seconds, so simply add the corresponding number of seconds to the timestamp:

$timeInFuture = time() + (60 * 60 * 24);

My favorite use case for read uncommited is to debug something that is happening inside a transaction.

Start your software under a debugger, while you are stepping through the lines of code, it opens a transaction and modifies your database. While the code is stopped, you can open a query analyzer, set on the read uncommited isolation level and make queries to see what is going on.

You also can use it to see if long running procedures are stuck or correctly updating your database.

It is great if your company loves to make overly complex stored procedures.

In my case, there is a single table which happens to be a device list from a router. If you wish to read the table using TR/TH/TD (row, header, data) instead of a matrix as mentioned above, you can do something like the following:

    List<TableRow> deviceTable = (from table in document.DocumentNode.SelectNodes(XPathQueries.SELECT_TABLE)
                                       from row in table?.SelectNodes(HtmlBody.TR)
                                       let rows = row.SelectSingleNode(HtmlBody.TR)
                                       where row.FirstChild.OriginalName != null && row.FirstChild.OriginalName.Equals(HtmlBody.T_HEADER)
                                       select new TableRow
                                       {
                                           Header = row.SelectSingleNode(HtmlBody.T_HEADER)?.InnerText,
                                           Data = row.SelectSingleNode(HtmlBody.T_DATA)?.InnerText}).ToList();
                                       }  

TableRow is just a simple object with Header and Data as properties. The approach takes care of null-ness and this case:

<tr>_x000D_
    <td width="28%">&nbsp;</td>_x000D_
</tr>

which is row without a header. The HtmlBody object with the constants hanging off of it are probably readily deduced but I apologize for it even still. I came from the world where if you have " in your code, it should either be constant or localizable.

You can do this with Jinja's tojson filter, which

Dumps a structure to JSON so that it’s safe to use in <script> tags [and] in any place in HTML with the notable exception of double quoted attributes.

For example, in your Python, write:

some_template.render(list_of_items=list_of_items)

... or, in the context of a Flask endpoint:

return render_template('your_template.html', list_of_items=list_of_items)

Then in your template, write this:

{% for item in list_of_items %}
<span onclick='somefunction({{item | tojson}})'>{{item}}</span><br>
{% endfor %}

(Note that the onclick attribute is single-quoted. This is necessary since |tojson escapes ' characters but not " characters in its output, meaning that it can be safely used in single-quoted HTML attributes but not double-quoted ones.)

Or, to use list_of_items in an inline script instead of an HTML attribute, write this:

<script>
const jsArrayOfItems = {{list_of_items | tojson}};
// ... do something with jsArrayOfItems in JavaScript ...
</script>

DON'T use json.dumps to JSON-encode variables in your Python code and pass the resulting JSON text to your template. This will produce incorrect output for some string values, and will expose you to XSS if you're trying to encode user-provided values. This is because Python's built-in json.dumps doesn't escape characters like < and > (which need escaping to safely template values into inline <script>s, as noted at https://html.spec.whatwg.org/multipage/scripting.html#restrictions-for-contents-of-script-elements) or single quotes (which need escaping to safely template values into single-quoted HTML attributes).

If you're using Flask, note that Flask injects a custom tojson filter instead of using Jinja's version. However, everything written above still applies. The two versions behave almost identically; Flask's just allows for some app-specific configuration that isn't available in Jinja's version.

Set is used for setting object references, as opposed to assigning a value.

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.

You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.

Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.

So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".

That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.

SOAP:

SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.

REST:

REST is a design concept.

The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)

Flickr's REST API goes further and lets you return images as well.

JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.

Until the day #pragma once becomes standard (that's not currently a priority for the future standards), I suggest you use it AND use guards, this way:

#ifndef BLAH_H
#define BLAH_H
#pragma once

// ...

#endif

The reasons are :

• #pragma once is not standard, so it is possible that some compiler don't provide the functionality. That said, all major compiler supports it. If a compiler don't know it, at least it will be ignored.
• As there is no standard behavior for #pragma once, you shouldn't assume that the behavior will be the same on all compiler. The guards will ensure at least that the basic assumption is the same for all compilers that at least implement the needed preprocessor instructions for guards.
• On most compilers, #pragma once will speed up compilation (of one cpp) because the compiler will not reopen the file containing this instruction. So having it in a file might help, or not, depending on the compiler. I heard g++ can do the same optimization when guards are detected but it have to be confirmed.

Using the two together you get the best of each compiler for this.

Now, if you don't have some automatic script to generate the guards, it might be more convenient to just use #pragma once. Just know what that means for portable code. (I'm using VAssistX to generate the guards and pragma once quickly)

You should almost always think your code in a portable way (because you don't know what the future is made of) but if you really think that it's not meant to be compiled with another compiler (code for very specific embedded hardware for example) then you should just check your compiler documentation about #pragma once to know what you're really doing.

No need to install 3rd party extensions!

There exists the javascript-snippet, which you can add as browser-bookmark and then activate on any site to track & modify the requests. It looks like:

For further instructions, review the github page.

I think that parse_str is what you're looking for, something like this should do the trick for you:

parse_str($_SERVER['QUERY_STRING'], $vars);

Then the $vars array will hold all the passed arguments.

If you have installed the application:

$ django-admin.py version
2.0

$.each($('input[type=number]'),function(){
  alert($(this).val());
});

This will alert the value of input type number fields

Python (until version 3) supports "old-style" and new-style classes. New-style classes are derived from object and are what you are using, and invoke their base class through super(), e.g.

class X(object):
  def __init__(self, x):
    pass

  def doit(self, bar):
    pass

class Y(X):
  def __init__(self):
    super(Y, self).__init__(123)

  def doit(self, foo):
    return super(Y, self).doit(foo)

Because python knows about old- and new-style classes, there are different ways to invoke a base method, which is why you've found multiple ways of doing so.

For completeness sake, old-style classes call base methods explicitly using the base class, i.e.

def doit(self, foo):
  return X.doit(self, foo)

But since you shouldn't be using old-style anymore, I wouldn't care about this too much.

Python 3 only knows about new-style classes (no matter if you derive from object or not).

Use the std::vector::vector(count, value) constructor that accepts an initial size and a default value:

std::vector<std::vector<int> > fog(
    ROW_COUNT,
    std::vector<int>(COLUMN_COUNT)); // Defaults to zero initial value

If a value other than zero, say 4 for example, was required to be the default then:

std::vector<std::vector<int> > fog(
    ROW_COUNT,
    std::vector<int>(COLUMN_COUNT, 4));

I should also mention uniform initialization was introduced in C++11, which permits the initialization of vector, and other containers, using {}:

std::vector<std::vector<int> > fog { { 1, 1, 1 },
                                    { 2, 2, 2 } };
                           

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

All you need to do is

$ git branch -rd origin/whatever 

It's that simple. There is no reason to call a gc here.

@Rynant 's solution worked for me. I had a couple of additional requirements though:

1. Don't PAUSE if encountered in bat file
2. Optionally, append bat file output to log file

Here's what I got working (finally):

[PS script code]

& runner.bat bat_to_run.bat logfile.txt

[runner.bat]

@echo OFF

REM This script can be executed from within a powershell script so that the bat file
REM passed as %1 will not cause execution to halt if PAUSE is encountered.
REM If {logfile} is included, bat file output will be appended to logfile.
REM
REM Usage:
REM runner.bat [path of bat script to execute] {logfile}

if not [%2] == [] GOTO APPEND_OUTPUT
@echo | call %1
GOTO EXIT

:APPEND_OUTPUT
@echo | call %1  1> %2 2>&1

:EXIT

You can either set the timeout when running your test:

mocha --timeout 15000

Or you can set the timeout for each suite or each test programmatically:

describe('...', function(){
  this.timeout(15000);

  it('...', function(done){
    this.timeout(15000);
    setTimeout(done, 15000);
  });
});

For more info see the docs.

The best way is to use mpack!

mpack -s "Subject" -d "./body.txt" "././image.png" mailadress

mpack - subject - body - attachment - mailadress

Depends on your needs, if you know what parent your looking for you can use the .parents() selector.

E.G: http://jsfiddle.net/HenryGarle/Kyp5g/2/

<div id="One">
    <div id="Two">
        <div id="Three">
            <div id="Four">

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


var top = $("#Four").parents("#One");

alert($(top).html());

Example using index:

//First parent - 2 levels up from #Four
// I.e Selects div#One
var topTwo = $("#Four").parents().eq(2);

alert($(topTwo ).html());

I had the same problem and ended up actually using border instead of padding.

I just checked with www.browserscope.org and with IE9 and Chrome 24 you can have 6 concurrent connections to a single domain, and up to 17 to multiple ones.

I agree with @Marlon. When you compile your C# project with the Release configuration, you will find into the "bin/Release" folder of your project the executable of your application. This SHOULD work for a simple application.

But, if your application have any dependencies on some external dll, I suggest you to create a SetupProject with VisualStudio. Doing so, the project wizard will find all dependencies of your application and add them (the librairies) to the installation folder. Finally, all you will have to do is run the setup on the users computer and install your software.

Just to add to Jon's coding if you needed to take it a step further, and do more than just one column you can add something like

Dim copyRange2 As Range
Dim copyRange3 As Range

Set copyRange2 =src.Range("B2:B" & lastRow)
Set copyRange3 =src.Range("C2:C" & lastRow)

copyRange2.SpecialCells(xlCellTypeVisible).Copy tgt.Range("B12")
copyRange3.SpecialCells(xlCellTypeVisible).Copy tgt.Range("C12")

put these near the other codings that are the same you can easily change the Ranges as you need.

I only add this because it was helpful for me. I'd assume Jon already knows this but for those that are less experienced sometimes it's helpful to see how to change/add/modify these codings. I figured since Ruya didn't know how to manipulate the original coding it could be helpful if one ever needed to copy over only 2 visibile columns, or only 3, etc. You can use this same coding, add in extra lines that are almost the same and then the coding is copying over whatever you need.

I don't have enough reputation to reply to Jon's comment directly so I have to post as a new comment, sorry.

*(myString.end() - 1) maybe? That's not exactly elegant either.

A python-esque myString.at(-1) would be asking too much of an already-bloated class.

KnexJs can be used as an SQL query builder in both Node.JS and the browser. I find it easy to use. Let try it - Knex.js

$ npm install knex --save
# Then add one of the following (adding a --save) flag:
$ npm install pg
$ npm install sqlite3
$ npm install mysql
$ npm install mysql2
$ npm install mariasql
$ npm install strong-oracle
$ npm install oracle
$ npm install mssql


var knex = require('knex')({
  client: 'mysql',
  connection: {
    host : '127.0.0.1',
    user : 'your_database_user',
    password : 'your_database_password',
    database : 'myapp_test'
  }
});

You can use it like this

knex.select('*').from('users')

or

knex('users').where({
  first_name: 'Test',
  last_name:  'User'
}).select('id')

On a German keyboard it's Ctrl + ´.

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

It is used when we want to wait for more than one thread to complete its task. It is similar to join in threads.

Where we can use CountDownLatch

Consider a scenario where we have requirement where we have three threads "A", "B" and "C" and we want to start thread "C" only when "A" and "B" threads completes or partially completes their task.

It can be applied to real world IT scenario

Consider a scenario where manager divided modules between development teams (A and B) and he wants to assign it to QA team for testing only when both the teams completes their task.

public class Manager {
    public static void main(String[] args) throws InterruptedException {
        CountDownLatch countDownLatch = new CountDownLatch(2);
        MyDevTeam teamDevA = new MyDevTeam(countDownLatch, "devA");
        MyDevTeam teamDevB = new MyDevTeam(countDownLatch, "devB");
        teamDevA.start();
        teamDevB.start();
        countDownLatch.await();
        MyQATeam qa = new MyQATeam();
        qa.start();
    }   
}

class MyDevTeam extends Thread {   
    CountDownLatch countDownLatch;
    public MyDevTeam (CountDownLatch countDownLatch, String name) {
        super(name);
        this.countDownLatch = countDownLatch;       
    }   
    @Override
    public void run() {
        System.out.println("Task assigned to development team " + Thread.currentThread().getName());
        try {
                Thread.sleep(2000);
        } catch (InterruptedException ex) {
                ex.printStackTrace();
        }
    System.out.println("Task finished by development team Thread.currentThread().getName());
            this.countDownLatch.countDown();
    }
}

class MyQATeam extends Thread {   
    @Override
    public void run() {
        System.out.println("Task assigned to QA team");
        try {
                Thread.sleep(2000);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        }
        System.out.println("Task finished by QA team");
    }
}

Output of above code will be:

Task assigned to development team devB

Task assigned to development team devA

Task finished by development team devB

Task finished by development team devA

Task assigned to QA team

Task finished by QA team

Here await() method waits for countdownlatch flag to become 0, and countDown() method decrements countdownlatch flag by 1.

Limitation of JOIN: Above example can also be achieved with JOIN, but JOIN can not be used in two scenarios:

1. When we use ExecutorService instead of Thread class to create threads.
2. Modify above example where Manager wants to handover code to QA team as soon as Development completes their 80% task. It means that CountDownLatch allow us to modify implementation which can be used to wait for another thread for their partial execution.

I wanted to note that the fourth part of Accepted Answer is wrong .

theApp.factory('mainInfo', function($http) { 

var obj = {content:null};

$http.get('content.json').success(function(data) {
    // you can do some processing here
    obj.content = data;
});    

return obj;    
});

The above code as @Karl Zilles wrote will fail because obj will always be returned before it receives data (thus the value will always be null) and this is because we are making an Asynchronous call.

The details of similar questions are discussed in this post

In Angular, use $promise to deal with the fetched data when you want to make an asynchronous call.

The simplest version is

theApp.factory('mainInfo', function($http) { 
    return {
        get:  function(){
            $http.get('content.json'); // this will return a promise to controller
        }
});


// and in controller

mainInfo.get().then(function(response) { 
    $scope.foo = response.data.contentItem;
});

The reason I don't use success and error is I just found out from the doc, these two methods are deprecated.

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead.

A similar thing happened to me. I created a branch called something like "Feat/name". I tried to pushed it using :

git push --set-upstream origin Feat/name

I got the same fatal error as you :

fatal: Feat/name cannot be resolved to branch

To solve it I created a new branch as I had very few files impacted. Then I listed my branches to delete the wrong one and it displayed with no cap :

• feat/name

I had used caps before but never on the first caracter. It looks like git doesn't like it...

To help understand why this surprising behavior isn't entirely terrible, consider an application which accepts a config file name as an argument:

config_root = "/etc/myapp.conf/"
file_name = os.path.join(config_root, sys.argv[1])

If the application is executed with:

$ myapp foo.conf

The config file /etc/myapp.conf/foo.conf will be used.

But consider what happens if the application is called with:

$ myapp /some/path/bar.conf

Then myapp should use the config file at /some/path/bar.conf (and not /etc/myapp.conf/some/path/bar.conf or similar).

It may not be great, but I believe this is the motivation for the absolute path behaviour.

The enums should not be qualified within the case label like what you have NDroid.guideView.GUIDE_VIEW_SEVEN_DAY, instead you should remove the qualification and use GUIDE_VIEW_SEVEN_DAY

Andy's solution does not work for me. Here I found another way:

git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`

Git: checkout by date

The process for timing out an operations is described in the documentation for signal.

The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.

Note that this will only work on UNIX.

Here's an implementation that creates a decorator (save the following code as timeout.py).

from functools import wraps
import errno
import os
import signal

class TimeoutError(Exception):
    pass

def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator

This creates a decorator called @timeout that can be applied to any long running functions.

So, in your application code, you can use the decorator like so:

from timeout import timeout

# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
    ...

# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
    ...

# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
    ...

/* cellpadding */
th, td { padding: 5px; }

/* cellspacing */
table { border-collapse: separate; border-spacing: 5px; } /* cellspacing="5" */
table { border-collapse: collapse; border-spacing: 0; }   /* cellspacing="0" */

/* valign */
th, td { vertical-align: top; }

/* align (center) */
table { margin: 0 auto; }

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

    @test
    testAbc() {
        myclass.setMyObj(myInterface); //it is good to have in @before method
        myClass.abc();
        verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
     }
}

To get the currently logged in user:

System.getProperty("user.name");

To get the host name of the machine:

InetAddress.getLocalHost().getHostName();

To answer the last part of your question, the Java API says that getHostName() will return

the host name for this IP address, or if the operation is not allowed by the security check, the textual representation of the IP address.

This is quite a hard task, ever harder if you want perfect results (impossible without using Word) as such the number of APIs that just do it all for you in pure Java and are open source is zero I believe (Update: I am wrong, see below).

Your basic options are as follows:

1. Using JNI/a C# web service/etc script MS Office (only option for 100% perfect results)
2. Using the available APIs script Open Office (90+% perfect)
3. Use Apache POI & iText (very large job, will never be perfect).

Update - 2016-02-11 Here is a cut down copy of my blog post on this subject which outlines existing products that support Word-to-PDF in Java.

Converting Microsoft Office (Word, Excel) documents to PDFs in Java

Three products that I know of can render Office documents:

yeokm1/docs-to-pdf-converter Irregularly maintained, Pure Java, Open Source Ties together a number of libraries to perform the conversion.

xdocreport Actively developed, Pure Java, Open Source It's Java API to merge XML document created with MS Office (docx) or OpenOffice (odt), LibreOffice (odt) with a Java model to generate report and convert it if you need to another format (PDF, XHTML...).

Snowbound Imaging SDK Closed Source, Pure Java Snowbound appears to be a 100% Java solution and costs over $2,500. It contains samples describing how to convert documents in the evaluation download.

OpenOffice API Open Source, Not Pure Java - Requires Open Office installed OpenOffice is a native Office suite which supports a Java API. This supports reading Office documents and writing PDF documents. The SDK contains an example in document conversion (examples/java/DocumentHandling/DocumentConverter.java). To write PDFs you need to pass the "writer_pdf_Export" writer rather than the "MS Word 97" one. Or you can use the wrapper API JODConverter.

JDocToPdf - Dead as of 2016-02-11 Uses Apache POI to read the Word document and iText to write the PDF. Completely free, 100% Java but has some limitations.

Actually… there is! Sort of. box-shadow defaults to color, just like border does.

According to http://dev.w3.org/.../#the-box-shadow

The color is the color of the shadow. If the color is absent, the used color is taken from the ‘color’ property.

In practice, you have to change the color property and leave box-shadow without a color:

box-shadow: 1px 2px 3px;
color: #a00;

Support

• Safari 6+
• Chrome 20+ (at least)
• Firefox 13+ (at least)
• IE9+ (IE8 doesn't support box-shadow at all)
