Programs & Examples On #Stream cipher

If you want "insert or replace" semantics, use this syntax:

A[key] = value;     // <-- insert or replace semantics

It's more efficient and readable than calls involving "ContainsKey()" or "Remove()" prior to "Add()".

So in your case:

rct3Features[items[0]] = items[1];

you can find a implementation of this (with some good explanation) in F# on fssnip

here are the important parts:

let GreatCircleDistance<[<Measure>] 'u> (R : float<'u>) (p1 : Location) (p2 : Location) =
    let degToRad (x : float<deg>) = System.Math.PI * x / 180.0<deg/rad>

    let sq x = x * x
    // take the sin of the half and square the result
    let sinSqHf (a : float<rad>) = (System.Math.Sin >> sq) (a / 2.0<rad>)
    let cos (a : float<deg>) = System.Math.Cos (degToRad a / 1.0<rad>)

    let dLat = (p2.Latitude - p1.Latitude) |> degToRad
    let dLon = (p2.Longitude - p1.Longitude) |> degToRad

    let a = sinSqHf dLat + cos p1.Latitude * cos p2.Latitude * sinSqHf dLon
    let c = 2.0 * System.Math.Atan2(System.Math.Sqrt(a), System.Math.Sqrt(1.0-a))

    R * c

Answer for Leandro Batista : just a problem with the regex expression.

 "use strict";_x000D_
 var dataFromDB = "testal";_x000D_
 _x000D_
  $('input[name="tbInput"]').on("change",function(){_x000D_
 var charToTest = $(this).val();_x000D_
 var howManyChars = charToTest.length;_x000D_
 var nrMatches = 0;_x000D_
 if(howManyChars !== 0){_x000D_
  charToTest = charToTest.charAt(0);_x000D_
  var regexp = new RegExp(charToTest,'gi');_x000D_
  var arrMatches = dataFromDB.match(regexp);_x000D_
  nrMatches = arrMatches ? arrMatches.length : 0;_x000D_

  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

What do you wanna count <input type="text" name="tbInput" value=""><br />_x000D_
Number of occurences = <span id="result">0</span>_x000D_
</div>

I also wrote a combination of Mockito and AspectJ: https://github.com/iirekm/varia/tree/develop/ajmock

Your example becomes:

when(() -> DriverManager.getConnection(...)).thenReturn(...);

You can use the compareTo() method from Java Date class

public int result = date.compareTo(Date anotherDate); 

Return Value: The function gives three return values specified below:

It returns the value 0 if the argument Date is equal to this Date. It returns a value less than 0 if this Date is before the Date argument. It returns a value greater than 0 if this Date is after the Date argument.

Add z-indez in class ui-datepicker

<style>
    .ui-datepicker{ z-index:1151 !important; }
</style>

For those arriving here after updating phpunit to version 6 or greater released on 2017-02-03 (e.g. with composer), you may be getting this error because phpunit code is now namespaced (check changelog).

You will need to refactor things like \PHPUnit_Framework_TestCase to \PHPUnit\Framework\TestCase

You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false). To add an extra column with only the non-reimbursed amounts, you would use something like:

=IF(B1="No", A1, 0)

and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.

I am aware there are existing answers which solves the problem. For those who are new to git, As of 02/11/2021, The default branch in git is "main" not "master" branch, The command will be

git push -u origin main

while importing libraries use the exact path to a file, including the directory relative to the current file, for example:

import Footer from './Footer/index.jsx'
import AddTodo from '../containers/AddTodo/index.jsx'
import VisibleTodoList from '../containers/VisibleTodoList/index.jsx'

Hope this may help

For read-only controls they are the same. For 2 way databinding, using a datasource in which you want to update, insert, etc with declarative databinding, you'll need to use Bind.

Imagine for example a GridView with a ItemTemplate and EditItemTemplate. If you use Bind or Eval in the ItemTemplate, there will be no difference. If you use Eval in the EditItemTemplate, the value will not be able to be passed to the Update method of the DataSource that the grid is bound to.

UPDATE: I've come up with this example:

<%@ Page Language="C#" %>

            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <%# Eval("Name") %>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox 
                            ID="edtName" 
                            runat="server" 
                            Text='<%# Bind("Name") %>' 
                        />
                    </EditItemTemplate>
                </asp:TemplateField>

And here's the definition of a custom class that serves as object data source:

public class CustomDataSource
{
    public class Model
    {
        public string Name { get; set; }
    }

    public IEnumerable<Model> Select()
    {
        return new[] 
        {
            new Model { Name = "some value" }
        };
    }

    public void Update(string Name)
    {
        // This method will be called if you used Bind for the TextBox
        // and you will be able to get the new name and update the
        // data source accordingly
    }

    public void Update()
    {
        // This method will be called if you used Eval for the TextBox
        // and you will not be able to get the new name that the user
        // entered
    }
}

I had some strings in the MongoDB Stored wich had to be reformated to a proper and valid dateTime field in the mongodb.

here is my code for the special date format: "2014-03-12T09:14:19.5303017+01:00"

but you can easyly take this idea and write your own regex to parse the date formats:

// format: "2014-03-12T09:14:19.5303017+01:00"
var myregexp = /(....)-(..)-(..)T(..):(..):(..)\.(.+)([\+-])(..)/;

db.Product.find().forEach(function(doc) { 
   var matches = myregexp.exec(doc.metadata.insertTime);

   if myregexp.test(doc.metadata.insertTime)) {
       var offset = matches[9] * (matches[8] == "+" ? 1 : -1);
       var hours = matches[4]-(-offset)+1
       var date = new Date(matches[1], matches[2]-1, matches[3],hours, matches[5], matches[6], matches[7] / 10000.0)
       db.Product.update({_id : doc._id}, {$set : {"metadata.insertTime" : date}})
       print("succsessfully updated");
    } else {
        print("not updated");
    }
})

You need to modify the Mapping Template

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

I find it easier to remember to just read it and then write it.

For example:

with open('file') as f:
    data = f.read()
with open('file', 'w') as f:
    f.write('hello')

IF NOT EXISTS(select * FROM sys.views where name = 'data_VVVV ')
    BEGIN
        CREATE VIEW data_VVVV AS 
        SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
    END
ELSE
    BEGIN
        ALTER VIEW data_VVVV AS 
        SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
    END

There is no such thing as an "epoch" in a specific timezone. The epoch is well-defined as a specific moment in time, so if you change the timezone, the time itself changes as well. Specifically, this time is Jan 1 1970 00:00:00 UTC. So time.time() returns the number of seconds since the epoch.

change your jquery method to

$(function () { /* DOM ready */
    $("#type").change(function () {
        alert('The option with value ' + $(this).val());
        //hide the element you want to hide here with
        //("id").attr("display","block"); // to show
        //("id").attr("display","none"); // to hide
    });
});

Compare this, without using nonlocal:

x = 0
def outer():
    x = 1
    def inner():
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 0

To this, using nonlocal, where inner()'s x is now also outer()'s x:

x = 0
def outer():
    x = 1
    def inner():
        nonlocal x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 2
# global: 0

If we were to use global, it would bind x to the properly "global" value:

x = 0
def outer():
    x = 1
    def inner():
        global x
        x = 2
        print("inner:", x)

    inner()
    print("outer:", x)

outer()
print("global:", x)

# inner: 2
# outer: 1
# global: 2

Maybe jQuery UI does what you are looking for. Its composed out of many handy helper functions like making objects draggable, droppable, resizable, sortable etc.

Take a look at sortable with connected lists.

The level of version information given out by an Apache server can be configured by the ServerTokens setting in its configuration.

I believe there is also a setting that controls whether the version appears in server error pages, although I can't remember what it is off the top of my head. If you don't have direct access to the server, and the server administrator is competent and doesn't want you to know the version they're running... I think you may be SOL.

To clarify, system variables are the same as environment variables. User environment variables are set per user and are different whenever a different user logs in. System wide environment variables are the same no matter what user logs on.

To access either the current value of a system wide variable or a user variable in Java, see below:

String javaHome = System.getenv("JAVA_HOME");

For more information on environment variables see this wikipedia page.

Also make sure the environment variable you are trying to read is properly set before invoking Java by doing a:

echo %MYENVVAR%

You should see the value of the environment variable. If not, you may need to reopen the shell (DOS) or log off and log back on.

Short answer:

[a[:,:j] for j in i]

What you are trying to do is not a vectorizable operation. Wikipedia defines vectorization as a batch operation on a single array, instead of on individual scalars:

In computer science, array programming languages (also known as vector or multidimensional languages) generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays.

...

... an operation that operates on entire arrays can be called a vectorized operation...

In terms of CPU-level optimization, the definition of vectorization is:

"Vectorization" (simplified) is the process of rewriting a loop so that instead of processing a single element of an array N times, it processes (say) 4 elements of the array simultaneously N/4 times.

The problem with your case is that the result of each individual operation has a different shape: (3, 1), (3, 2) and (3, 3). They can not form the output of a single vectorized operation, because the output has to be one contiguous array. Of course, it can contain (3, 1), (3, 2) and (3, 3) arrays inside of it (as views), but that's what your original array a already does.

What you're really looking for is just a single expression that computes all of them:

[a[:,:j] for j in i]

... but it's not vectorized in a sense of performance optimization. Under the hood it's plain old for loop that computes each item one by one.

if you are receiving data from a serial port, make sure you are using the right baudrate (and the other configs ) : decoding using (utf-8) but the wrong config will generate the same error

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

to check your serial port config on linux use : stty -F /dev/ttyUSBX -a

The simple way is:

function Foo(a) {
  var that=this;

  function privateMethod() { .. }

  // public methods
  that.add = function(b) {
    return a + b;
  };
  that.avg = function(b) {
    return that.add(b) / 2; // calling another public method
  };
}

var x = new Foo(10);
alert(x.add(2)); // 12
alert(x.avg(20)); // 15

The reason for that is that this can be bound to something else if you give a method as an event handler, so you save the value during instantiation and use it later.

Edit: it's definitely not the best way, just a simple way. I'm waiting for good answers too!

Just wanted to say Magnus' answer above did it for me, but for the second "overlay" that needs to be "overflow"

helpers : {
  overlay : {
    css : { 'overflow' : 'hidden' }
  }
}

You'll need a UITapGestureRecognizer. To set up use this:

override func viewDidLoad()
{
    super.viewDidLoad()

    let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))
    imageView.isUserInteractionEnabled = true
    imageView.addGestureRecognizer(tapGestureRecognizer)
}

@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{
    let tappedImage = tapGestureRecognizer.view as! UIImageView

    // Your action
}

(You could also use a UIButton and assign an image to it, without text and than simply connect an IBAction)

For example:

you can use:

df %>% filter(!is.na(a))

to remove the NA in column a.

Yes. Use Reflection. With Reflection, you can do things like:

//given object of some type
object myObjectFromSomewhere;
Type myObjOriginalType = myObjectFromSomewhere.GetType();
PropertyInfo[] myProps = myObjOriginalType.GetProperties();

And then you can use the resulting PropertyInfo classes to compare all manner of things.

Someone pointed me to this thread because I had this same issue but it didn't work for me. After hours of searching I found a solution using this - https://github.com/rewish/jquery-bgswitcher#readme

It has a few other options other than fade too.

Some online API's work pretty well: ocr.space and Google Cloud Vision. Both of these are free, as long as you do less than 1000 OCR's per month. You can drag & drop an image to do a quick manual test to see how they perform for your images.

I find OCR.space easier to use (no messing around with nuget libraries), but, for my purpose, Google Cloud Vision provided slightly better results than OCR.space.

Google Cloud Vision example:

GoogleCredential cred = GoogleCredential.FromJson(json);
Channel channel = new Channel(ImageAnnotatorClient.DefaultEndpoint.Host, ImageAnnotatorClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
ImageAnnotatorClient client = ImageAnnotatorClient.Create(channel);
Image image = Image.FromStream(stream);

EntityAnnotation googleOcrText = client.DetectText(image).First();
Console.Write(googleOcrText.Description);

OCR.space example:

string uri = $"https://api.ocr.space/parse/imageurl?apikey=helloworld&url={imageUri}";
string responseString = WebUtilities.DoGetRequest(uri);
OcrSpaceResult result = JsonConvert.DeserializeObject<OcrSpaceResult>(responseString);
if ((!result.IsErroredOnProcessing) && !String.IsNullOrEmpty(result.ParsedResults[0].ParsedText))
  return result.ParsedResults[0].ParsedText;

So, there is no difference between MySQL "database" and MySQL "schema": these are two names for the same thing - a namespace for tables and other DB objects.

For people with Oracle background: MySQL "database" a.k.a. MySQL "schema" corresponds to Oracle schema. The difference between MySQL and Oracle CREATE SCHEMA commands is that in Oracle the CREATE SCHEMA command does not actually create a schema but rather populates it with tables and views. And Oracle's CREATE DATABASE command does a very different thing than its MySQL counterpart.

The correct way to do it would be:

adb -s 123abc12 shell getprop

Which will give you a list of all available properties and their values. Once you know which property you want, you can give the name as an argument to getprop to access its value directly, like this:

adb -s 123abc12 shell getprop ro.product.model

The details in adb devices -l consist of the following three properties: ro.product.name, ro.product.model and ro.product.device.

Note that ADB shell ends lines with \r\n, which depending on your platform might or might not make it more difficult to access the exact value (e.g. instead of Nexus 7 you might get Nexus 7\r).

PEP 8 is good, the only thing that i wish it came down harder on was the Tabs-vs-Spaces holy war.

Basically if you are starting a project in python, you need to choose Tabs or Spaces and then shoot all offenders on sight.

You could also use Regular Expressions:

SELECT * FROM TABLE WHERE REGEXP_LIKE (TABLE.NAME,'IgNoReCaSe','i');

It depends on what you're trying to do.

You currently have it set up as a normalized database, which is fine, and the way you are doing it is appropriate.

However, there are other ways of doing it.

You could have a posts collection that has imbedded comments for each post with references to the users that you can iteratively query to get. You could store the user's name with the comments, you could store them all in one document.

The thing with NoSQL is it's designed for flexible schemas and very fast reading and writing. In a typical Big Data farm the database is the biggest bottleneck, you have fewer database engines than you do application and front end servers...they're more expensive but more powerful, also hard drive space is very cheap comparatively. Normalization comes from the concept of trying to save space, but it comes with a cost at making your databases perform complicated Joins and verifying the integrity of relationships, performing cascading operations. All of which saves the developers some headaches if they designed the database properly.

With NoSQL, if you accept that redundancy and storage space aren't issues because of their cost (both in processor time required to do updates and hard drive costs to store extra data), denormalizing isn't an issue (for embedded arrays that become hundreds of thousands of items it can be a performance issue, but most of the time that's not a problem). Additionally you'll have several application and front end servers for every database cluster. Have them do the heavy lifting of the joins and let the database servers stick to reading and writing.

TL;DR: What you're doing is fine, and there are other ways of doing it. Check out the mongodb documentation's data model patterns for some great examples. http://docs.mongodb.org/manual/data-modeling/

You should use #!/usr/bin/env bash for portability: different *nixes put bash in different places, and using /usr/bin/env is a workaround to run the first bash found on the PATH. And sh is not bash.

If you're running 32bit JVM, change heap size to smaller would probabaly help. You can do this by passing args to java directly or through enviroment variables like following,

java -Xms128M -Xmx512M
JAVA_OPTS="-Xms128M -Xmx512M"

For 64bit JVM, bigger heap size like -Xms512M -Xmx1536M should work.

Run java -version or java -d32, java--d64 for Java7 to check which version you're running.

Just add an else then:

function checkform()
{
    var f = document.forms["theform"].elements;
    var cansubmit = true;

    for (var i = 0; i < f.length; i++) {
        if (f[i].value.length == 0) cansubmit = false;
    }

    if (cansubmit) {
        document.getElementById('submitbutton').disabled = false;
    }
    else {
        document.getElementById('submitbutton').disabled = 'disabled';
    }
}

From Blogging Developer:

In order to understand the difference between keydown and keypress, it is useful to understand the difference between a "character" and a "key". A "key" is a physical button on the computer's keyboard while a "character" is a symbol typed by pressing a button. In theory, the keydown and keyup events represent keys being pressed or released, while the keypress event represents a character being typed. The implementation of the theory is not same in all browsers.

Note: You can also try out the Key Event Tester (available on the above-mentioned site) to understand this concept.

In some rare cases you might want to implement your own String serialization.

But that probably is a bad idea unless you know what you are doing. (e.g. serializing for I/O with a batch file)

Something like that would do the trick (and it would be easy to edit by hand/batch), but be careful that some more checks should be done, like that name doesn't contain a newline.

public string name {get;set;}
public int age {get;set;}

Person(string serializedPerson) 
{
    string[] tmpArray = serializedPerson.Split('\n');
    if(tmpArray.Length>2 && tmpArray[0].Equals("#")){
        this.name=tmpArray[1];
        this.age=int.TryParse(tmpArray[2]);
    }else{
        throw new ArgumentException("Not a valid serialization of a person");
    }
}

public string SerializeToString()
{
    return "#\n" +
           name + "\n" + 
           age;
}

It’s doing integer division. You can make one of the numbers a Float by adding .0:

9.0 / 5  #=> 1.8
9 / 5.0  #=> 1.8

Had the issue again when i moved from one machine to another and had everything reinstalled. In my case, i'm using both 32bit and 64bit Oracle ODP.NET installs.

When listing the assemblies on my new machine i ended up with the following list

 C:\oracle\product\11.2.0\X64\odp.net\bin\4>gacutil /l|findstr Oracle.DataAccess

only 64bit DLLs to be seen here.

I couldn't see it from the web.config but the one i was using was a 32bit version.

When checking my old machine with the GACutil, i saw more DLLs, also the X86 ones.

Fixed by reapplying the registration process(both x32/x64 version referenced here)

OraProvCfg.exe /action:gac /providerpath:C:\oracle\product\11.2.0\x32\ODP.NET\bin\4\Oracle.DataAccess.dll

OraProvCfg.exe /action:gac /providerpath:C:\oracle\product\11.2.0\x64\ODP.NET\bin\4\Oracle.DataAccess.dll

after that , Visual Studio was a happy bunny and compiled everything again for me.

You can use SVGs to connect two divs using only HTML and CSS:

<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#777; position:absolute;"></div>
<div id="div2" style="width: 100px; height: 100px; top:300px; left:300px; background:#333; position:absolute;"></div>

(please use seperate css file for styling)

Create a svg line and use this line to connect above divs

<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="350" stroke="black"/></svg>

where,

x1,y1 indicates center of first div and
x2,y2 indicates center of second div

You can check how it looks in the snippet below

<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#777; position:absolute;"></div>_x000D_
<div id="div2" style="width: 100px; height: 100px; top:300px; left:300px; background:#333; position:absolute;"></div>_x000D_
_x000D_
<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="350" stroke="black"/></svg>

Take a look at Shell MegaPack control set. It provides Windows Explorer like folder/file browsing with most of the features and functionality like context menus, renaming, drag-drop, icons, overlay icons, thumbnails, etc

Care and feeding of Eclipse's memory hunger is a pain...

More or less, keep trying smaller amounts til it works, that's your max.

There are two aproaches that I can see that would work for checking for any bit being set.

Aproach A

if (letter != 0)
{
}

This works as long as you don't mind checking for all bits, including non-defined ones too!

Aproach B

if ((letter & Letters.All) != 0)
{
}

This only checks the defined bits, as long as Letters.All represents all of the possible bits.

For specific bits (one or more set), use Aproach B replacing Letters.All with the bits that you want to check for (see below).

if ((letter & Letters.AB) != 0)
{
}

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

DanSingerman has a very good solution for this question.

The only reliable source for the language is in the HTTP-request header. So you need a server-side script to reply the request-header or at least the Accept-Language field back to you.

Here is a very simple Node.js server which should be compatible with DanSingermans jQuery plugin.

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end(JSON.stringify(req.headers));
}).listen(80,'0.0.0.0');

UPDATE:3 Now that I have upgraded to new Router, @borislemke's approach will not work if you use CanDeactivate guard. I'm degrading to my old method, ie: this answer

UPDATE2: Router events in new-router look promising and the answer by @borislemke seems to cover the main aspect of spinner implementation, I havent't tested it but I recommend it.

UPDATE1: I wrote this answer in the era of Old-Router, when there used to be only one event route-changed notified via router.subscribe(). I also felt overload of the below approach and tried to do it using only router.subscribe(), and it backfired because there was no way to detect canceled navigation. So I had to revert back to lengthy approach(double work).

If you know your way around in Angular2, this is what you'll need

Boot.ts

import {bootstrap} from '@angular/platform-browser-dynamic';
import {MyApp} from 'path/to/MyApp-Component';
import { SpinnerService} from 'path/to/spinner-service';

bootstrap(MyApp, [SpinnerService]);

Root Component- (MyApp)

import { Component } from '@angular/core';
import { SpinnerComponent} from 'path/to/spinner-component';
@Component({
  selector: 'my-app',
  directives: [SpinnerComponent],
  template: `
     <spinner-component></spinner-component>
     <router-outlet></router-outlet>
   `
})
export class MyApp { }

Spinner-Component (will subscribe to Spinner-service to change the value of active accordingly)

import {Component} from '@angular/core';
import { SpinnerService} from 'path/to/spinner-service';
@Component({
  selector: 'spinner-component',
  'template': '<div *ngIf="active" class="spinner loading"></div>'
})
export class SpinnerComponent {
  public active: boolean;

  public constructor(spinner: SpinnerService) {
    spinner.status.subscribe((status: boolean) => {
      this.active = status;
    });
  }
}

Spinner-Service (bootstrap this service)

Define an observable to be subscribed by spinner-component to change the status on change, and function to know and set the spinner active/inactive.

import {Injectable} from '@angular/core';
import {Subject} from 'rxjs/Subject';
import 'rxjs/add/operator/share';

@Injectable()
export class SpinnerService {
  public status: Subject<boolean> = new Subject();
  private _active: boolean = false;

  public get active(): boolean {
    return this._active;
  }

  public set active(v: boolean) {
    this._active = v;
    this.status.next(v);
  }

  public start(): void {
    this.active = true;
  }

  public stop(): void {
    this.active = false;
  }
}

All Other Routes' Components

(sample):

import { Component} from '@angular/core';
import { SpinnerService} from 'path/to/spinner-service';
@Component({
   template: `<div *ngIf="!spinner.active" id="container">Nothing is Loading Now</div>`
})
export class SampleComponent {

  constructor(public spinner: SpinnerService){} 

  ngOnInit(){
    this.spinner.stop(); // or do it on some other event eg: when xmlhttp request completes loading data for the component
  }

  ngOnDestroy(){
    this.spinner.start();
  }
}

what is the exec function and its family.

The exec function family is all functions used to execute a file, such as execl, execlp, execle, execv, and execvp.They are all frontends for execve and provide different methods of calling it.

why is this function used

Exec functions are used when you want to execute (launch) a file (program).

and how does it work.

They work by overwriting the current process image with the one that you launched. They replace (by ending) the currently running process (the one that called the exec command) with the new process that has launched.

For more details: see this link.

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

From tensorflow github:

import tensorflow as tf

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

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

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

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

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

print(c)

Expected output:

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

The JavaScript Object() constructor makes an Object that you can assign members to.

myObj = new Object()
myObj.key = value;
myObj[key2] = value2;   // Alternative

If you want to use the primitive wrapper classes, this will work, but all java types are signed by default.

public static void main(String[] args) {
    Integer i=5;
    Byte b = Byte.valueOf(i+""); //converts i to String and calls Byte.valueOf()
    System.out.println(b);
    System.out.println(Integer.valueOf(b));
}

Have you already looked at adding a check constraint on that column which would restrict values? Something like:

CREATE TABLE SomeTable
(
   Id int NOT NULL,
   Frequency varchar(200),
   CONSTRAINT chk_Frequency CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
)

Use the instructions for resetting the root password - but instead of resetting the root password, we'll going to forcefully INSERT a record into the mysql.user table

In the init file, use this instead

INSERT INTO mysql.user (Host, User, Password) VALUES ('%', 'root', password('YOURPASSWORD'));
GRANT ALL ON *.* TO 'root'@'%' WITH GRANT OPTION;

git log --format="%h" | tail -1 gives you the commit hash (ie 0dd89fb), which you can feed into other commands, by doing something like

git diff `git log --format="%h" --after="1 day"| tail -1`..HEAD to view all the commits in the last day.

A way to have separate implementation is as follows.

//inner_foo.h

template <typename T>
struct Foo
{
    void doSomething(T param);
};


//foo.tpp
#include "inner_foo.h"
template <typename T>
void Foo<T>::doSomething(T param)
{
    //implementation
}


//foo.h
#include <foo.tpp>

//main.cpp
#include <foo.h>

inner_foo has the forward declarations. foo.tpp has the implementation and include inner_foo.h; and foo.h will have just one line, to include foo.tpp.

On compile time, contents of foo.h are copied to foo.tpp and then the whole file is copied to foo.h after which it compiles. This way, there is no limitations, and the naming is consistent, in exchange for one extra file.

I do this because static analyzers for the code break when it does not see the forward declarations of class in *.tpp. This is annoying when writing code in any IDE or using YouCompleteMe or others.

In many cases, continuing to scrape data from a website even when the server is requesting you not to is unethical. However, in the cases where it isn't, you can utilize a list of public proxies in order to scrape a website with many different IP addresses.

Either use:

pip install xlrd

And if you are using conda, use

conda install -c anaconda xlrd

That's it. good luck.

git diff `git merge-base master branch`..branch

Merge base is the point where branch diverged from master.

Git diff supports a special syntax for this:

git diff master...branch

You must not swap the sides because then you would get the other branch. You want to know what changed in branch since it diverged from master, not the other way round.

Loosely related:

• Finding a branch point with Git?
• How can I see what branch another branch was forked from?

Note that .. and ... syntax does not have the same semantics as in other Git tools. It differs from the meaning specified in man gitrevisions.

Quoting man git-diff:

• git diff [--options] <commit> <commit> [--] [<path>…]

  This is to view the changes between two arbitrary <commit>.

• git diff [--options] <commit>..<commit> [--] [<path>…]

  This is synonymous to the previous form. If <commit> on one side is omitted, it will have the same effect as using HEAD instead.

• git diff [--options] <commit>...<commit> [--] [<path>…]

  This form is to view the changes on the branch containing and up to the second <commit>, starting at a common ancestor of both <commit>. "git diff A...B" is equivalent to "git diff $(git-merge-base A B) B". You can omit any one of <commit>, which has the same effect as using HEAD instead.

Just in case you are doing something exotic, it should be noted that all of the <commit> in the above description, except in the last two forms that use ".." notations, can be any <tree>.

For a more complete list of ways to spell <commit>, see "SPECIFYING REVISIONS" section in gitrevisions[7]. However, "diff" is about comparing two endpoints, not ranges, and the range notations ("<commit>..<commit>" and "<commit>...<commit>") do not mean a range as defined in the "SPECIFYING RANGES" section in gitrevisions[7].

The pickle Python library implements binary protocols for serializing and de-serializing a Python object.

When you import torch (or when you use PyTorch) it will import pickle for you and you don't need to call pickle.dump() and pickle.load() directly, which are the methods to save and to load the object.

In fact, torch.save() and torch.load() will wrap pickle.dump() and pickle.load() for you.

A state_dict the other answer mentioned deserves just few more notes.

What state_dict do we have inside PyTorch? There are actually two state_dicts.

The PyTorch model is torch.nn.Module has model.parameters() call to get learnable parameters (w and b). These learnable parameters, once randomly set, will update over time as we learn. Learnable parameters are the first state_dict.

The second state_dict is the optimizer state dict. You recall that the optimizer is used to improve our learnable parameters. But the optimizer state_dict is fixed. Nothing to learn in there.

Because state_dict objects are Python dictionaries, they can be easily saved, updated, altered, and restored, adding a great deal of modularity to PyTorch models and optimizers.

Let's create a super simple model to explain this:

import torch
import torch.optim as optim

model = torch.nn.Linear(5, 2)

# Initialize optimizer
optimizer = optim.SGD(model.parameters(), lr=0.001, momentum=0.9)

print("Model's state_dict:")
for param_tensor in model.state_dict():
    print(param_tensor, "\t", model.state_dict()[param_tensor].size())

print("Model weight:")    
print(model.weight)

print("Model bias:")    
print(model.bias)

print("---")
print("Optimizer's state_dict:")
for var_name in optimizer.state_dict():
    print(var_name, "\t", optimizer.state_dict()[var_name])

This code will output the following:

Model's state_dict:
weight   torch.Size([2, 5])
bias     torch.Size([2])
Model weight:
Parameter containing:
tensor([[ 0.1328,  0.1360,  0.1553, -0.1838, -0.0316],
        [ 0.0479,  0.1760,  0.1712,  0.2244,  0.1408]], requires_grad=True)
Model bias:
Parameter containing:
tensor([ 0.4112, -0.0733], requires_grad=True)
---
Optimizer's state_dict:
state    {}
param_groups     [{'lr': 0.001, 'momentum': 0.9, 'dampening': 0, 'weight_decay': 0, 'nesterov': False, 'params': [140695321443856, 140695321443928]}]

Note this is a minimal model. You may try to add stack of sequential

model = torch.nn.Sequential(
          torch.nn.Linear(D_in, H),
          torch.nn.Conv2d(A, B, C)
          torch.nn.Linear(H, D_out),
        )

Note that only layers with learnable parameters (convolutional layers, linear layers, etc.) and registered buffers (batchnorm layers) have entries in the model's state_dict.

Non learnable things, belong to the optimizer object state_dict, which contains information about the optimizer's state, as well as the hyperparameters used.

The rest of the story is the same; in the inference phase (this is a phase when we use the model after training) for predicting; we do predict based on the parameters we learned. So for the inference, we just need to save the parameters model.state_dict().

torch.save(model.state_dict(), filepath)

And to use later model.load_state_dict(torch.load(filepath)) model.eval()

Note: Don't forget the last line model.eval() this is crucial after loading the model.

Also don't try to save torch.save(model.parameters(), filepath). The model.parameters() is just the generator object.

On the other side, torch.save(model, filepath) saves the model object itself, but keep in mind the model doesn't have the optimizer's state_dict. Check the other excellent answer by @Jadiel de Armas to save the optimizer's state dict.

One other thing to note, if you updated a legacy app that had structs to use classes you might run into the following issue:

Old code has structs, code was cleaned up and these changed to classes. A virtual function or two was then added to the new updated class.

When virtual functions are in classes then internally the compiler will add extra pointer to the class data to point to the functions.

How this would break old legacy code is if in the old code somewhere the struct was cleared using memfill to clear it all to zeros, this would stomp the extra pointer data as well.

This Worked for me ! For Angular 2 , Call child component method in parent component

Parent.component.ts

    import { Component, OnInit, ViewChild } from '@angular/core';
    import { ChildComponent } from '../child/child'; 
    @Component({ 
               selector: 'parent-app', 
               template: `<child-cmp></child-cmp>` 
              }) 
    export class parentComponent implements OnInit{ 
        @ViewChild(ChildComponent ) child: ChildComponent ; 

        ngOnInit() { 
           this.child.ChildTestCmp(); } 
}

Child.component.ts

import { Component } from '@angular/core';
@Component({ 
  selector: 'child-cmp', 
  template: `<h2> Show Child Component</h2><br/><p> {{test }}</p> ` 
})
export class ChildComponent {
  test: string;
  ChildTestCmp() 
  { 
    this.test = "I am child component!"; 
  }
 }

If you launch your program with -enableassertions (or -ea for short) then this statement

assert cond;

is equivalent to

if (!cond)
    throw new AssertionError();

If you launch your program without this option, the assert statement will have no effect.

For example, assert d >= 0 && d <= s.length();, as posted in your question, is equivalent to

if (!(d >= 0 && d <= s.length()))
    throw new AssertionError();

(If you launched with -enableassertions that is.)

Formally, the Java Language Specification: 14.10. The assert Statement says the following:

14.10. The assert Statement
An assertion is an assert statement containing a boolean expression. An assertion is either enabled or disabled. If the assertion is enabled, execution of the assertion causes evaluation of the boolean expression and an error is reported if the expression evaluates to false. If the assertion is disabled, execution of the assertion has no effect whatsoever.

Where "enabled or disabled" is controlled with the -ea switch and "An error is reported" means that an AssertionError is thrown.

And finally, a lesser known feature of assert:

You can append : "Error message" like this:

assert d != null : "d is null";

to specify what the error message of the thrown AssertionError should be.

If you only care about the local machine, you can rely on the psutil package. You can either:

1. Check all ports used by a specific pid:

   proc = psutil.Process(pid)
   print proc.connections()
   

2. Check all ports used on the local machine:

   print psutil.net_connections()
   

It works on Windows too.

1. Find the element in array and get its position
2. Remove using the position

var array = new Array();_x000D_
  _x000D_
array.push('123');_x000D_
array.push('456');_x000D_
array.push('789');_x000D_
                 _x000D_
var _searchedIndex = $.inArray('456',array);_x000D_
alert(_searchedIndex );_x000D_
if(_searchedIndex >= 0){_x000D_
  array.splice(_searchedIndex,1);_x000D_
  alert(array );_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>

• inArray() - helps you to find the position.
• splice() - helps you to remove the element in that position.

As @Musa comments it, it seems that the reason is that:

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

The simplest Hello World example...

$hello = "Hello World"
$hello | Out-File c:\debug.txt

(1) SQLite has a built in rowid pseudo-column so this works:

sqldf("select min(rowid) rowid, id, string 
               from test 
               group by id")

giving:

  rowid id string
1     1  1      A
2     3  2      B
3     5  3      C
4     7  4      D
5     9  5      E

(2) Also sqldf itself has a row.names= argument:

sqldf("select min(cast(row_names as real)) row_names, id, string 
              from test 
              group by id", row.names = TRUE)

giving:

  id string
1  1      A
3  2      B
5  3      C
7  4      D
9  5      E

(3) A third alternative which mixes the elements of the above two might be even better:

sqldf("select min(rowid) row_names, id, string 
               from test 
               group by id", row.names = TRUE)

giving:

  id string
1  1      A
3  2      B
5  3      C
7  4      D
9  5      E

Note that all three of these rely on a SQLite extension to SQL where the use of min or max is guaranteed to result in the other columns being chosen from the same row. (In other SQL-based databases that may not be guaranteed.)

I totally agree with the answers before. I just like to mention that the difference between expose and ports is part of the security concept in docker. It goes hand in hand with the networking of docker. For example:

Imagine an application with a web front-end and a database back-end. The outside world needs access to the web front-end (perhaps on port 80), but only the back-end itself needs access to the database host and port. Using a user-defined bridge, only the web port needs to be opened, and the database application doesn’t need any ports open, since the web front-end can reach it over the user-defined bridge.

This is a common use case when setting up a network architecture in docker. So for example in a default bridge network, not ports are accessible from the outer world. Therefor you can open an ingresspoint with "ports". With using "expose" you define communication within the network. If you want to expose the default ports you don't need to define "expose" in your docker-compose file.

I wrote the following function to print dicts, lists, and tuples in a more readable format:

def printplus(obj):
    """
    Pretty-prints the object passed in.

    """
    # Dict
    if isinstance(obj, dict):
        for k, v in sorted(obj.items()):
            print u'{0}: {1}'.format(k, v)

    # List or tuple            
    elif isinstance(obj, list) or isinstance(obj, tuple):
        for x in obj:
            print x

    # Other
    else:
        print obj

Example usage in iPython:

>>> dict_example = {'c': 1, 'b': 2, 'a': 3}
>>> printplus(dict_example)
a: 3
b: 2
c: 1

>>> tuple_example = ((1, 2), (3, 4), (5, 6), (7, 8))
>>> printplus(tuple_example)
(1, 2)
(3, 4)
(5, 6)
(7, 8)

You have 3 choices:

1. atoi

This is probably the fastest if you're using it in performance-critical code, but it does no error reporting. If the string does not begin with an integer, it will return 0. If the string contains junk after the integer, it will convert the initial part and ignore the rest. If the number is too big to fit in int, the behaviour is unspecified.

2. sscanf

Some error reporting, and you have a lot of flexibility for what type to store (signed/unsigned versions of char/short/int/long/long long/size_t/ptrdiff_t/intmax_t).

The return value is the number of conversions that succeed, so scanning for "%d" will return 0 if the string does not begin with an integer. You can use "%d%n" to store the index of the first character after the integer that's read in another variable, and thereby check to see if the entire string was converted or if there's junk afterwards. However, like atoi, behaviour on integer overflow is unspecified.

3. strtol and family

Robust error reporting, provided you set errno to 0 before making the call. Return values are specified on overflow and errno will be set. You can choose any number base from 2 to 36, or specify 0 as the base to auto-interpret leading 0x and 0 as hex and octal, respectively. Choices of type to convert to are signed/unsigned versions of long/long long/intmax_t.

If you need a smaller type you can always store the result in a temporary long or unsigned long variable and check for overflow yourself.

Since these functions take a pointer to pointer argument, you also get a pointer to the first character following the converted integer, for free, so you can tell if the entire string was an integer or parse subsequent data in the string if needed.

Personally, I would recommend the strtol family for most purposes. If you're doing something quick-and-dirty, atoi might meet your needs.

As an aside, sometimes I find I need to parse numbers where leading whitespace, sign, etc. are not supposed to be accepted. In this case it's pretty damn easy to roll your own for loop, eg.,

for (x=0; (unsigned)*s-'0'<10; s++) 
    x=10*x+(*s-'0');

Or you can use (for robustness):

if (isdigit(*s))
    x=strtol(s, &s, 10);
else /* error */

You need to go to Settings and set under the Java compiler the following:

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

You could bind the DropDownList to a data source (DataTable, List, DataSet, SqlDataSource, etc).

For example, if you wanted to use a DataTable:

ddlSubject.DataSource = subjectsTable;
ddlSubject.DataTextField = "SubjectNamne";
ddlSubject.DataValueField = "SubjectID";
ddlSubject.DataBind();

EDIT - More complete example

private void LoadSubjects()
{

    DataTable subjects = new DataTable();

    using (SqlConnection con = new SqlConnection(connectionString))
    {

        try
        {
            SqlDataAdapter adapter = new SqlDataAdapter("SELECT SubjectID, SubjectName FROM Students.dbo.Subjects", con);
            adapter.Fill(subjects);

            ddlSubject.DataSource = subjects;
            ddlSubject.DataTextField = "SubjectNamne";
            ddlSubject.DataValueField = "SubjectID";
            ddlSubject.DataBind();
        }
        catch (Exception ex)
        {
            // Handle the error
        }

    }

    // Add the initial item - you can add this even if the options from the
    // db were not successfully loaded
    ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));

}

To set an initial value via the markup, rather than code-behind, specify the option(s) and set the AppendDataBoundItems attribute to true:

<asp:DropDownList ID="ddlSubject" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Text="<Select Subject>" Value="0" />
</asp:DropDownList>

You could then bind the DropDownList to a DataSource in the code-behind (just remember to remove:

ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));

from the code-behind, or you'll have two "" items.

Columns("A:E").Select

Can be directly replaced by

Columns(1).Resize(, 5).EntireColumn.Select

Where 1 can be replaced by a variable

n = 5
Columns(n).Resize(, n+4).EntireColumn.Select

In my opinion you are best dealing with a block of columns rather than looping through columns n to n + 4 as it is more efficient.

In addition, using select will slow your code down. So instead of selecting your columns and then performing an action on the selection try instead to perform the action directly. Below is an example to change the colour of columns A-E to yellow.

Columns(1).Resize(, 5).EntireColumn.Interior.Color = 65535

You can give the input element a font opacity of 0. This will hide the text field without hiding the 'Choose Files' button.

No javascript required, clear cross browser as far back as IE 9

E.g.,

input {color: rgba(0, 0, 0, 0);}

Just to improve YCR's answer:

1) I added black lines on x and y axis. Otherwise they are made transparent too.

2) I added a transparent theme to the legend key. Otherwise, you will get a fill there, which won't be very esthetic.

Finally, note that all those work only with pdf and png formats. jpeg fails to produce transparent graphs.

MyTheme_transparent <- theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent"), # get rid of legend panel bg
    legend.key = element_rect(fill = "transparent", colour = NA), # get rid of key legend fill, and of the surrounding
    axis.line = element_line(colour = "black") # adding a black line for x and y axis
)

typedef defines a new data type. So you can have:

typedef char* my_string;
typedef struct{
  int member1;
  int member2;
} my_struct;

So now you can declare variables with these new data types

my_string s;
my_struct x;

s = "welcome";
x.member1 = 10;

For enum, things are a bit different - consider the following examples:

enum Ranks {FIRST, SECOND};
int main()
{
   int data = 20;
   if (data == FIRST)
   {
      //do something
   }
}

using typedef enum creates an alias for a type:

typedef enum Ranks {FIRST, SECOND} Order;
int main()
{
   Order data = (Order)20;  // Must cast to defined type to prevent error

   if (data == FIRST)
   {
      //do something
   }
}

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

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

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

If you have the numpy package:

In [16]: x = [1,2,3,4]    
    ...: import numpy
    ...: numpy.average(x)

Out[16]: 2.5

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="footer">
  <div class="container">
    <div class="row">
      <div class="col-xs-4">
        <p>Hello there</p>
      </div>
      <div class="col-xs-4 text-center">
        <a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>

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

UPDATE(OCT 2017)

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet" />
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container footer">
  <div class="d-flex justify-content-between">
    <div class="p-1">
      <p>Hello there</p>
    </div>
    <div class="p-1">
      <a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>
      <a href="#" class="btn btn-warning" onclick="changeBack()">Rs</a>
    </div>
    <div class="p-1">
      <a href="#"><i class="fa fa-facebook-square fa-2x"></i></a>

• Only one import needed.
• No if statement needed.
• Use the client built-in exception as intended.

Ex:

from boto3 import client

cli = client('iam')
try:
    cli.create_user(
        UserName = 'Brian'
    )
except cli.exceptions.EntityAlreadyExistsException:
    pass

a CloudWatch example:

cli = client('logs')
try:
    cli.create_log_group(
        logGroupName = 'MyLogGroup'
    )
except cli.exceptions.ResourceAlreadyExistsException:
    pass

There is the use case of a mirror of Docker Hub (such as Artifactory or a custom one), which I haven't seen mentioned here. This is one of the most valid cases where changing the default registry is needed.

Luckily, Docker (at least version 19.03.3) allows you to set a mirror (tested in Docker CE). I don't know if this will work with additional images pushed to that mirror that aren't on Docker Hub, but I do know it will use the mirror instead. Docker documentation: https://docs.docker.com/registry/recipes/mirror/#configure-the-docker-daemon.

Essentially, you need to add "registry-mirrors": [] to the /etc/docker/daemon.json configuration file. So if you have a mirror hosted at https://my-docker-repo.my.company.com, your /etc/docker/daemon.json should contain:

{
  "registry-mirrors": ["https://my-docker-repo-mirror.my.company.com"]
}

Afterwards, restart the Docker daemon. Now if you do a docker pull postgres:12, Docker should fetch the image from the mirror instead of directly from Docker Hub. This is much better than prepending all images with my-docker-repo.my.company.com

Storing previous url in a session variable is bad, because the user might right click on multiple pages and then come back and save.

unless you save the previous url in the session variable to a hidden field in the form and after save header( "Location: save URL of calling page" );

Dupe: How do I set an HTML class attribute in Markdown?

Natively? No. But...

No, Markdown's syntax can't. You can set ID values with Markdown Extra through.

You can use regular HTML if you like, and add the attribute markdown="1" to continue markdown-conversion within the HTML element. This requires Markdown Extra though.

<p class='specialParagraph' markdown='1'>
**Another paragraph** which allows *Markdown* within it.
</p>

Possible Solution: (Untested and intended for <blockquote>)

I found the following online:

Function

function _DoBlockQuotes_callback($matches) {

    ...cut...

    //add id and class details...
    $id = $class = '';
    if(preg_match_all('/\{(?:([#.][-_:a-zA-Z0-9 ]+)+)\}/',$bq,$matches)) {
        foreach ($matches[1] as $match) {
            if($match[0]=='#') $type = 'id';
            else $type = 'class';
            ${$type} = ' '.$type.'="'.trim($match,'.# ').'"';
        }
        foreach ($matches[0] as $match) {
            $bq = str_replace($match,'',$bq);
        }
    }

    return _HashBlock(
        "<blockquote{$id}{$class}>\n$bq\n</blockquote>"
    ) . "\n\n";
}

Markdown

>{.className}{#id}This is the blockquote

Result

<blockquote id="id" class="className">
    <p>This is the blockquote</p>
</blockquote>

>>> from datetime import datetime
>>> year, month, day = map(int, my_date.split('-'))
>>> date_object = datetime(year, month, day)

You can do this also in kotlin like this:

    contentView.apply {
        // Set the content view to 0% opacity but visible, so that it is visible
        // (but fully transparent) during the animation.
        alpha = 0f
        visibility = View.VISIBLE

        // Animate the content view to 100% opacity, and clear any animation
        // listener set on the view.
        animate()
                .alpha(1f)
                .setDuration(resources.getInteger(android.R.integer.config_mediumAnimTime).toLong())
                .setListener(null)
    }

You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.

A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.

Courtesy of this thread: https://community.oracle.com/thread/362226?tstart=-1

With a clustered index the rows are stored physically on the disk in the same order as the index. Therefore, there can be only one clustered index.

With a non clustered index there is a second list that has pointers to the physical rows. You can have many non clustered indices, although each new index will increase the time it takes to write new records.

It is generally faster to read from a clustered index if you want to get back all the columns. You do not have to go first to the index and then to the table.

Writing to a table with a clustered index can be slower, if there is a need to rearrange the data.

You can use & in place of &

http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Predefined%5Fentities%5Fin%5FXML

Use arrow function:

Request.prototype.start = () => {
    if( this.stay_open == true ) {
        this.open({msg: 'listen'});
    } else {

    }
};

Your Comparator would look like this:

public class GraduationCeremonyComparator implements Comparator<GraduationCeremony> {
    public int compare(GraduationCeremony o1, GraduationCeremony o2) {
        int value1 = o1.campus.compareTo(o2.campus);
        if (value1 == 0) {
            int value2 = o1.faculty.compareTo(o2.faculty);
            if (value2 == 0) {
                return o1.building.compareTo(o2.building);
            } else {
                return value2;
            }
        }
        return value1;
    }
}

Basically it continues comparing each successive attribute of your class whenever the compared attributes so far are equal (== 0).

I had the same error, what solve my problem was. In my library instead of using compile or implementation i use "api". So in the end my dependencies:

dependencies {

testApi 'junit:junit:4.12'
api 'com.android.support:percent:26.0.0-beta2'

Here is my solution:

git log --all --full-history --oneline -- <RELATIVE_FILE_PATH>
git checkout <COMMIT_SHA>^ -- <RELATIVE_FILE_PATH>

This works for me. Has a nice delayed action going on.

var $mouseX = 0, $mouseY = 0;
var $xp = 0, $yp =0;

$(document).mousemove(function(e){
    $mouseX = e.pageX;
    $mouseY = e.pageY;    
});

var $loop = setInterval(function(){
// change 12 to alter damping higher is slower
$xp += (($mouseX - $xp)/12);
$yp += (($mouseY - $yp)/12);
$("#moving_div").css({left:$xp +'px', top:$yp +'px'});  
}, 30);

Nice and simples

Passing null would be better. The full codes is like:

WebView wv = (WebView)this.findViewById(R.id.myWebView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, "<html>...</html>", "text/html", "utf-8", null);

My async function

const getAllRedis = async (key) => {
  let obj = [];

  await client.hgetall(key, (err, object) => {
    console.log(object);
    _.map(object, (ob)=>{
      obj.push(JSON.parse(ob));
    })
    return obj;
    // res.send(obj);
});
}

Based on analysis done by Google-Chrome Dev Tools' Lighthouse Audit,

For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds.

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

AccessType.PROPERTY: The EJB persistence implementation will load state into your class via JavaBean "setter" methods, and retrieve state from your class using JavaBean "getter" methods. This is the default.

AccessType.FIELD: State is loaded and retrieved directly from your class' fields. You do not have to write JavaBean "getters" and "setters".

This is typically because you have not set the origin alias on your Git repository.

Try

git remote add origin URL_TO_YOUR_REPO

This will add an alias in your .git/config file for the remote clone/push/pull site URL. This URL can be found on your repository Overview page.

If you are looking for a command-line based solution, you can ignore my answer. I am gonna suggest you to use GitKraken. It's an extraordinary git UI client. It shows the Git tree on the homepage. You can just look at them and know what is going on with the project. Just select a specific commit, right-click on it and select the option 'Create a branch here'. It will give you a text box to enter the branch name. Enter branch name, select 'OK' and you are set. It's really very easy to use.

Also very helpful, while investigating the Environment.SpecialFolder enum. Use LINQPad or create a solution and execute this code:

Enum.GetValues(typeof(Environment.SpecialFolder))
    .Cast<Environment.SpecialFolder>()
    .Select(specialFolder => new
    {
        Name = specialFolder.ToString(),
        Path = Environment.GetFolderPath(specialFolder)
    })
    .OrderBy(item => item.Path.ToLower())

In runtime problems like these firstly open logcat if you are using android studio, try to analyse trace tree, go to the beginning from where exception started to rise, since that is usually the source of the problem. Now check for two things:

1. Check in device file explorer(on the bottom right) there exist a database created by you. mostly you find it in DATA -> DATA -> com.example.hpc.demo(your pakage name) -> DATABASE -> demo.db

2. Check that in your helper class you have added required '/' for example like below
   DB_location = "data/data/" + mcontext.getPackageName() + "/database/";

Regarding objects, especially in lazy-load scenario, one should consider garbage collector is running in idle CPU cycles, so presuming you're going into trouble when a lot of objects are loading small time penalty will solve the memory freeing.

Use time_nanosleep to enable GC to collect memory. Setting variable to null is desirable.

Tested on production server, originally the job consumed 50MB and then was halted. After nanosleep was used 14MB was constant memory consumption.

One should say this depends on GC behaviour which may change from PHP version to version. But it works on PHP 5.3 fine.

eg. this sample (code taken form VirtueMart2 google feed)

for($n=0; $n<count($ids); $n++)
{
    //unset($product); //usefull for arrays
    $product = null
    if( $n % 50 == 0 )
    {
        // let GC do the memory job
        //echo "<mem>" . memory_get_usage() . "</mem>";//$ids[$n];
        time_nanosleep(0, 10000000);

    $product = $productModel->getProductSingle((int)$ids[$n],true, true, true);
    ...

First, let's define some terms:

• RESTful:

  One can characterise applications conforming to the REST constraints described in this section as "RESTful".[15] If a service violates any of the required constraints, it cannot be considered RESTful.

  according to wikipedia.

• stateless constraint:

  We next add a constraint to the client-server interaction: communication must be stateless in nature, as in the client-stateless-server (CSS) style of Section 3.4.3 (Figure 5-3), such that each request from client to server must contain all of the information necessary to understand the request, and cannot take advantage of any stored context on the server. Session state is therefore kept entirely on the client.

  according to the Fielding dissertation.

So server side sessions violate the stateless constraint of REST, and so RESTfulness either.

As such, to the client, a session cookie is exactly the same as any other HTTP header based authentication mechanism, except that it uses the Cookie header instead of the Authorization or some other proprietary header.

By session cookies you store the client state on the server and so your request has a context. Let's try to add a load balancer and another service instance to your system. In this case you have to share the sessions between the service instances. It is hard to maintain and extend such a system, so it scales badly...

In my opinion there is nothing wrong with cookies. The cookie technology is a client side storing mechanism in where the stored data is attached automatically to cookie headers by every request. I don't know of a REST constraint which has problem with that kind of technology. So there is no problem with the technology itself, the problem is with its usage. Fielding wrote a sub-section about why he thinks HTTP cookies are bad.

From my point of view:

• authentication is not prohibited for RESTfulness (otherwise there'd be little use in RESTful services)
• authentication is done by sending an authentication token in the request, usually the header
• this authentication token needs to be obtained somehow and may be revoked, in which case it needs to be renewed
• the authentication token needs to be validated by the server (otherwise it wouldn't be authentication)

Your point of view was pretty solid. The only problem was with the concept of creating authentication token on the server. You don't need that part. What you need is storing username and password on the client and send it with every request. You don't need more to do this than HTTP basic auth and an encrypted connection:

• Figure 1. - Stateless authentication by trusted clients

You probably need an in-memory auth cache on server side to make things faster, since you have to authenticate every request.

Now this works pretty well by trusted clients written by you, but what about 3rd party clients? They cannot have the username and password and all the permissions of the users. So you have to store separately what permissions a 3rd party client can have by a specific user. So the client developers can register they 3rd party clients, and get an unique API key and the users can allow 3rd party clients to access some part of their permissions. Like reading the name and email address, or listing their friends, etc... After allowing a 3rd party client the server will generate an access token. These access token can be used by the 3rd party client to access the permissions granted by the user, like so:

• Figure 2. - Stateless authentication by 3rd party clients

So the 3rd party client can get the access token from a trusted client (or directly from the user). After that it can send a valid request with the API key and access token. This is the most basic 3rd party auth mechanism. You can read more about the implementation details in the documentation of every 3rd party auth system, e.g. OAuth. Of course this can be more complex and more secure, for example you can sign the details of every single request on server side and send the signature along with the request, and so on... The actual solution depends on your application's need.

Absolutely. Try this:

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);

Don't forget also to create the constant PICK_IMAGE, so you can recognize when the user comes back from the image gallery Activity:

public static final int PICK_IMAGE = 1;

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == PICK_IMAGE) {
        //TODO: action
    }
}

That's how I call the image gallery. Put it in and see if it works for you.

EDIT:

This brings up the Documents app. To allow the user to also use any gallery apps they might have installed:

    Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT);
    getIntent.setType("image/*");

    Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    pickIntent.setType("image/*");

    Intent chooserIntent = Intent.createChooser(getIntent, "Select Image");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] {pickIntent});

    startActivityForResult(chooserIntent, PICK_IMAGE);

You have a type-o:

its: height: 200x;

and it should be: height: 200px; also check the image url; it should be in the same directory it seems.

Also, dont use 'px' at null (aka '0') values. 0px, 0em, 0% is still 0. :)

top: 0px;

is the same with:

top: 0;

Good Luck!

public static long randomLong(long min, long max)
{
    try
    {
        Random  random  = new Random();
        long    result  = min + (long) (random.nextDouble() * (max - min));
        return  result;
    }
    catch (Throwable t) {t.printStackTrace();}
    return 0L;
}

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

table-layout: fixed will get force the cells to fit the table (and not the other way around), e.g.:

<table style="border: 1px solid black; width: 100%; word-wrap:break-word;
              table-layout: fixed;">
  <tr>
    <td>
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
        bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
    </td>
  </tr>
</table>

This worked for me :

npm install -g local-cors-proxy

API endpoint that we want to request that has CORS issues:

https://www.yourdomain.com/test/list

Start Proxy:

lcp --proxyUrl https://www.yourdomain.com

 Proxy Active 

 Proxy Url: http://www.yourdomain.com:28080
 Proxy Partial: proxy
 PORT: 8010

Then in your client code, new API endpoint:

http://localhost:8010/proxy/test/list

End result will be a request to https://www.yourdomain.ie/test/list without the CORS issues!

You may directly right-click on the table name - that also shows the "Import Data.." option.Then you can follow few simple steps & succeed.

Do anyone know how to import a new table with data from excel?

Derived from @Goner Doug answer, with a few things updated:
- using REPLACE where possible
- conversion of predefined entities like é (I chose the ones I needed :-)
- some conversion of list tags <ul> and <li>

Parameters are directly supported in MVC by simply adding parameters onto your action methods. Given an action like the following:

public ActionResult GetImages(string artistName, string apiKey)

MVC will auto-populate the parameters when given a URL like:

/Artist/GetImages/?artistName=cher&apiKey=XXX

One additional special case is parameters named "id". Any parameter named ID can be put into the path rather than the querystring, so something like:

public ActionResult GetImages(string id, string apiKey)

would be populated correctly with a URL like the following:

/Artist/GetImages/cher?apiKey=XXX

In addition, if you have more complicated scenarios, you can customize the routing rules that MVC uses to locate an action. Your global.asax file contains routing rules that can be customized. By default the rule looks like this:

routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
        );

If you wanted to support a url like

/Artist/GetImages/cher/api-key

you could add a route like:

routes.MapRoute(
            "ArtistImages",                                              // Route name
            "{controller}/{action}/{artistName}/{apikey}",                           // URL with parameters
            new { controller = "Home", action = "Index", artistName = "", apikey = "" }  // Parameter defaults
        );

and a method like the first example above.

MATLAB doesn't respond to Ctrl-C while executing a mex implemented function such as svd. Also when MATLAB is allocating big chunk of memory it doesn't respond. A good practice is to always run your functions for small amount of data, and when all test passes run it for actual scale. When time is an issue, you would want to analyze how much time each segment of code runs as well as their rough time complexity.

This is caused by a gradle dependency on some out-of-date thing which causes the error. Remove gradle dependencies until the error stops appearing. For me, it was:

implementation 'org.apache.directory.studio:org.apache.commons.io:2.4'

This line needed to be updated to a newer version such as:

api group: 'commons-io', name: 'commons-io', version: '2.6'

Look at this awesome new library which is available via gradle :)

build.gradle: compile 'com.apptakk.http_request:http-request:0.1.2'

new HttpRequestTask(
    new HttpRequest("http://httpbin.org/post", HttpRequest.POST, "{ \"some\": \"data\" }"),
    new HttpRequest.Handler() {
      @Override
      public void response(HttpResponse response) {
        if (response.code == 200) {
          Log.d(this.getClass().toString(), "Request successful!");
        } else {
          Log.e(this.getClass().toString(), "Request unsuccessful: " + response);
        }
      }
    }).execute();

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

Like this:

DateTime.Now.ToString("MMMM yyyy")

For more information, see DateTime Format Strings.

Including views:

SELECT owner, table_name as table_view
  FROM dba_tables
UNION ALL
SELECT owner, view_name as table_view
  FROM DBA_VIEWS

Similar to older answers, but a bit simpler, without the lambda:

filter_kwargs = {
    'field_a': 123,
    'field_b__in': (3, 4, 5, ),
}

To filter these two conditions using OR:

Item.objects.filter(Q(field_a=123) | Q(field_b__in=(3, 4, 5, ))

To get the same result programmatically:

list_of_Q = [Q(**{key: val}) for key, val in filter_kwargs.items()]
Item.objects.filter(reduce(operator.or_, list_of_Q))

(broken in two lines here, for clarity)

operator is in standard library: import operator
From docstring:

or_(a, b) -- Same as a | b.

For Python3, reduce is not a builtin any more but is still in the standard library: from functools import reduce

P.S.

Don't forget to make sure list_of_Q is not empty - reduce() will choke on empty list, it needs at least one element.

First, I purchased the domain in GoDaddy, and when I clicked this link https://www.google.com/settings/security/lesssecureapps I didn't have the option, it show this message "The domain administrator manages these settings", so I go to the Admin Console https://admin.google.com/

There is this option

Then appears the option that I needed in

I like the -=[4] way mentioned in other answers to delete the elements whose value is 4.

But there is this way:

[2,4,6,3,8,6].delete_if { |i| i == 6 }
=> [2, 4, 3, 8]

mentioned somewhere in "Basic Array Operations", after it mentions the map function.

In the Eclipse download folder make the entries in the eclipse.ini file :

or what ever values you want.

I know this is an old question, but I've found another answer that worked better for me and it doesn't seem to appear in any of the answers.

Create a layout xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="5dip"
    android:paddingBottom="5dip"
    android:paddingStart="10dip"
    android:paddingEnd="10dip">

<ImageView

    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_gravity="center_vertical"
    android:scaleType="fitXY" />

<TextView
    android:id="@+id/shoe_select_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:textSize="20sp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"/>

</LinearLayout>

Create a ListPopupWindow and a map with the content:

ListPopupWindow popupWindow;
List<HashMap<String, Object>> data = new ArrayList<>();
HashMap<String, Object> map = new HashMap<>();
    map.put(TITLE, getString(R.string.left));
    map.put(ICON, R.drawable.left);
    data.add(map);
    map = new HashMap<>();
    map.put(TITLE, getString(R.string.right));
    map.put(ICON, R.drawable.right);
    data.add(map);

Then on click, display the menu using this function:

private void showListMenu(final View anchor) {
    popupWindow = new ListPopupWindow(this);

    ListAdapter adapter = new SimpleAdapter(
            this,
            data,
            R.layout.shoe_select,
            new String[] {TITLE, ICON}, // These are just the keys that the data uses (constant strings)
            new int[] {R.id.shoe_select_text, R.id.shoe_select_icon}); // The view ids to map the data to

    popupWindow.setAnchorView(anchor);
    popupWindow.setAdapter(adapter);
    popupWindow.setWidth(400);
    popupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            switch (position){
                case 0:
                    devicesAdapter.setSelectedLeftPosition(devicesList.getChildAdapterPosition(anchor));
                    break;
                case 1:
                    devicesAdapter.setSelectedRightPosition(devicesList.getChildAdapterPosition(anchor));
                    break;
                default:
                    break;
            }
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    devicesAdapter.notifyDataSetChanged();
                }
            });
            popupWindow.dismiss();
        }
    });
    popupWindow.show();
}

Response with RxJS

Say Like something in Angular

size$: Observable<number> = fromEvent(window, 'resize').pipe(
            debounceTime(250),
            throttleTime(300),
            mergeMap(() => of(document.body.clientHeight)),
            distinctUntilChanged(),
            startWith(document.body.clientHeight),
          );

If manual subscription desired (Or Not Angular)

this.size$.subscribe((g) => {
      console.log('clientHeight', g);
    })

Since my intial startWith Value might be incorrect (dispatch for correction)

window.dispatchEvent(new Event('resize'));

In say Angular (I could..)

<div class="iframe-container"  [style.height.px]="size$ | async" >..

    alert("blabla");_x000D_
  };_x000D_
_x000D_
  var foo = document.getElementById("fooBar");_x000D_
  //Append the element in page (in span).  _x000D_
  foo.appendChild(element);_x000D_
}_x000D_
document.getElementById("btnAdd").onclick = function() {_x000D_
  add("text");_x000D_
};

<input type="button" id="btnAdd" value="Add Text Field">_x000D_
<p id="fooBar">Fields:</p>

Now, instead of setting the onclick property of the element, which is called "DOM0 event handling," you might consider using addEventListener (on most browsers) or attachEvent (on all but very recent Microsoft browsers) — you'll have to detect and handle both cases — as that form, called "DOM2 event handling," has more flexibility. But if you don't need multiple handlers and such, the old DOM0 way works fine.

Separately from the above: You might consider using a good JavaScript library like jQuery, Prototype, YUI, Closure, or any of several others. They smooth over browsers differences like the addEventListener / attachEvent thing, provide useful utility features, and various other things. Obviously there's nothing a library can do that you can't do without one, as the libraries are just JavaScript code. But when you use a good library with a broad user base, you get the benefit of a huge amount of work already done by other people dealing with those browsers differences, etc.

I managed to do something similar by using this URL:

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

It downloads a complete list of stock symbols using the Yahoo YQL API, including the stock name, stock symbol, and industry ID. What it doesn't seem to have is any sort of stock symbol modifiers. E.g. for Rogers Communications Inc, it only downloads RCI, not RCI-A.TO, RCI-B.TO, etc. I haven't found a source for that information yet - if anyone knows of a way to automate downloading that, I'd like to hear it. Also, it'd be nice to find a way to download some sort of relation between the stock symbol and the exchange it's traded on, since some are traded on multiple exchanges, or maybe I only want to look at stuff on the TSX or something.

In your onResume() section of the Activity you can do call the method bringKeyboard();

 onResume() {
     EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
     bringKeyboard(yourEditText);
 }


  protected boolean bringKeyboard(EditText view) {
    if (view == null) {
        return false;
    }
    try {
      // Depending if edittext has some pre-filled values you can decide whether to bring up soft keyboard or not
        String value = view.getText().toString();
        if (value == null) {
            InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            return true;
        }
    } catch (Exception e) {
        Log.e(TAG, "decideFocus. Exception", e);
    }
    return false;
  }

Target parameters:

float width = 1024;
float height = 768;
var brush = new SolidBrush(Color.Black);

Your original file:

var image = new Bitmap(file);

Target sizing (scale factor):

float scale = Math.Min(width / image.Width, height / image.Height);

The resize including brushing canvas first:

var bmp = new Bitmap((int)width, (int)height);
var graph = Graphics.FromImage(bmp);

// uncomment for higher quality output
//graph.InterpolationMode = InterpolationMode.High;
//graph.CompositingQuality = CompositingQuality.HighQuality;
//graph.SmoothingMode = SmoothingMode.AntiAlias;

var scaleWidth = (int)(image.Width * scale);
var scaleHeight = (int)(image.Height * scale);

graph.FillRectangle(brush, new RectangleF(0, 0, width, height));
graph.DrawImage(image, ((int)width - scaleWidth)/2, ((int)height - scaleHeight)/2, scaleWidth, scaleHeight);

And don't forget to do a bmp.Save(filename) to save the resulting file.

If you set ON UPDATE CURRENT_TIMESTAMP it will take current time when row data update in table.

 CREATE TABLE bar(
        `create_time` TIMESTAMP CURRENT_TIMESTAMP,
        `update_time` TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
    )

"In the default mode, Dot (.) matches any character except a newline. If the DOTALL flag has been specified, this matches any character including a newline." (python Doc)

So, if you want to evaluate dot literaly, I think you should put it in square brackets:

>>> p = re.compile(r'\b(\w+[.]\w+)')
>>> resp = p.search("blah blah blah [email protected] blah blah")
>>> resp.group()
'test.this'

You mean something like this?

<?php

$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);

foreach ( $json_output->trends as $trend )
{
    echo "{$trend->name}\n";
}

I don't know why all the answers over here are so confusing. I found a quite simpler one. Use a css class for the asp:menu, say, mainMenu and all the menu items under this will be "a tags" when rendered into HTML. So you just have to provide :hover property to those "a tags" in your CSS. See below for the example:

<asp:Menu ID="mnuMain" Orientation="Horizontal" runat="server" Font-Bold="True" Width="100%" CssClass="mainMenu">
  <Items>
    <asp:MenuItem Text="Home"></asp:MenuItem>
    <asp:MenuItem Text="About Us"></asp:MenuItem>
  </Items>
</asp:Menu>

And in the CSS, write:

.mainMenu { background:#900; }
.mainMenu a { color:#fff; }
.mainMenu a:hover { background:#c00; color:#ff9; }

I hope this helps. :)

Using EntityManagerFactory approach allows us to use callback method annotations like @PrePersist, @PostPersist,@PreUpdate with no extra configuration.

Using similar callbacks while using SessionFactory will require extra efforts.

Pandas DataFrame columns are Pandas Series when you pull them out, which you can then call x.tolist() on to turn them into a Python list. Alternatively you cast it with list(x).

import pandas as pd

data_dict = {'one': pd.Series([1, 2, 3], index=['a', 'b', 'c']),
             'two': pd.Series([1, 2, 3, 4], index=['a', 'b', 'c', 'd'])}

df = pd.DataFrame(data_dict)

print(f"DataFrame:\n{df}\n")
print(f"column types:\n{df.dtypes}")

col_one_list = df['one'].tolist()

col_one_arr = df['one'].to_numpy()

print(f"\ncol_one_list:\n{col_one_list}\ntype:{type(col_one_list)}")
print(f"\ncol_one_arr:\n{col_one_arr}\ntype:{type(col_one_arr)}")

Output:

DataFrame:
   one  two
a  1.0    1
b  2.0    2
c  3.0    3
d  NaN    4

column types:
one    float64
two      int64

Another way of adding schema dynamically or if you want to change it to something else

DECLARE @schema AS VARCHAR(256) = 'dbo.'
--User can also use SELECT SCHEMA_NAME() to get the default schema name


DECLARE @ID INT

declare @SQL nvarchar(max) = 'EXEC ' + @schema +'spSelectCaseBookingDetails @BookingID = '  + CAST(@ID AS NVARCHAR(10))

No need to cast @ID if it is nvarchar or varchar

execute (@SQL)

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

After coming back to my own question after 5 year and seeing so many people found this useful, a little update.

A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.

{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}

or

{% set list1 = variable1.split(';') %}
{% for item in list1 %}
    <p>{{ item }}<p/>
{% endfor %} 

or

{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

Let's say you have the following directory structure where you want to generate javadocs on file1.java and file2.java (package com.test), with the javadocs being placed in C:\javadoc\test:

C:\
|
+--javadoc\
|  |
|  +--test\
|
+--projects\
   |
   +--com\
      |
      +--test\
         |
         +--file1.java
         +--file2.java

In the command terminal, navigate to the root of your package: C:\projects. If you just want to generate the standard javadocs on all the java files inside the project, run the following command (for multiple packages, separate the package names by spaces):

C:\projects> javadoc -d [path to javadoc destination directory] [package name]

C:\projects> javadoc -d C:\javadoc\test com.test

If you want to run javadocs from elsewhere, you'll need to specify the sourcepath. For example, if you were to run javadocs in in C:\, you would modify the command as such:

C:\> javadoc -d [path to javadoc destination directory] -sourcepath [path to package directory] [package name]

C:\> javadoc -d C:\javadoc\test -sourcepath C:\projects com.test

If you want to run javadocs on only selected .java files, then add the source filenames separated by spaces (you can use an asterisk (*) for a wildcard). Make sure to include the path to the files:

C:\> javadoc -d [path to javadoc destination directory] [source filenames]

C:\> javadoc -d C:\javadoc\test C:\projects\com\test\file1.java

This trick works for me. Hope this could help you. Let's save the followings as checkRunningProcess.sh

#!/bin/bash
ps_out=`ps -ef | grep $1 | grep -v 'grep' | grep -v $0`
result=$(echo $ps_out | grep "$1")
if [[ "$result" != "" ]];then
    echo "Running"
else
    echo "Not Running"
fi

Make the checkRunningProcess.sh executable.And then use it.
Example to use.

20:10 $ checkRunningProcess.sh proxy.py
Running
20:12 $ checkRunningProcess.sh abcdef
Not Running

Use ampersand to specify the parent selector.

SCSS syntax:

    > a {

        content: "";
    }

    &:after {
        content: "* * *";
    }
}

For Python 3:

import urllib.request, urllib.error

url = 'http://www.google.com/asdfsf'
try:
    conn = urllib.request.urlopen(url)
except urllib.error.HTTPError as e:
    # Return code error (e.g. 404, 501, ...)
    # ...
    print('HTTPError: {}'.format(e.code))
except urllib.error.URLError as e:
    # Not an HTTP-specific error (e.g. connection refused)
    # ...
    print('URLError: {}'.format(e.reason))
else:
    # 200
    # ...
    print('good')

387 constructors?? That's your main problem. How about this instead?

DateTime.TryParseExact(
    "2010-08-20T15:00:00Z",
    @"yyyy-MM-dd\THH:mm:ss\Z",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, 
    out d);
d.ToString()

produces

I would say to add a paragraph with a period in it and style it like so:

<p class="center">.</p>

O(2^N)

O(2^N) denotes an algorithm whose growth doubles with each additon to the input data set. The growth curve of an O(2^N) function is exponential - starting off very shallow, then rising meteorically. An example of an O(2^N) function is the recursive calculation of Fibonacci numbers:

int Fibonacci (int number)
{
if (number <= 1) return number;
return Fibonacci(number - 2) + Fibonacci(number - 1);
}

    view.delegate = self
    view.dataSource = self
    view.separatorStyle = .none

Diagnostics:

You can see which java version Maven uses by running "mvn --version"

Solution for Debian:

The mvn script sets the JAVA_HOME env variable internally by looking for javac (which javac). Therefore, if you have multiple java versions installed concurrently, e.g. JDK 6 and JDK 7 and use the Debian Alternatives system to choose between them, even though you changed the alternative for "java" to JDK 7, mvn will still use JDK 6. You have to change the alternative for "javac", too. E.g.:

# update-alternatives --set javac /usr/lib/jvm/java-7-openjdk-amd64/bin/javac

EDIT:

Actually, an even better solution is to use update-java-alternatives (e.g.)

# update-java-alternatives -s java-1.7.0-openjdk-amd64

as detailed in https://wiki.debian.org/JavaPackage, because this will change all the alternatives to various Java tools (there's a dozen or so).

.push() is a method of the Built-in Array Object

It is not related to jQuery in any way.

You are defining a literal Object with

// Object
var stuff = {};

You can define a literal Array like this

// Array
var stuff = [];

then

stuff.push(element);

Arrays actually get their bracket syntax stuff[index] inherited from their parent, the Object. This is why you are able to use it the way you are in your first example.

This is often used for effortless reflection for dynamically accessing properties

stuff = {}; // Object

stuff['prop'] = 'value'; // assign property of an 
                         // Object via bracket syntax

stuff.prop === stuff['prop']; // true

As always, the devil is in the detail...

On Mac OS X v10.7.5 (Lion), to fix some Django error, in my ~/.bash_profile I've set:

export LANG=en_EN.UTF-8
export LC_COLLATE=$LANG
export LC_CTYPE=$LANG
export LC_MESSAGES=$LANG
export LC_MONETARY=$LANG
export LC_NUMERIC=$LANG
export LC_TIME=$LANG
export LC_ALL=$LANG

And in turn for a long time I got that warning when using Perl.

My bad! As I've realized much later, my system is en_US.UTF-8! I fixed it simply by changing from

export LANG=en_EN.UTF-8

to

export LANG=en_US.UTF-8

If all your inputs / textarea have a name, then you can filter all from event.target:

onSubmit(event){
  const fields = Array.prototype.slice.call(event.target)
      .filter(el => el.name)
      .reduce((form, el) => ({
        ...form,
        [el.name]: el.value,
      }), {})
}

Totally uncontrolled form without onChange methods, value, defaultValue...

I would say parsing it is the only way you can really entirely tell. Exception will be raised by python's json.loads() function (almost certainly) if not the correct format. However, the the purposes of your example you can probably just check the first couple of non-whitespace characters...

I'm not familiar with the JSON that facebook sends back, but most JSON strings from web apps will start with a open square [ or curly { bracket. No images formats I know of start with those characters.

Conversely if you know what image formats might show up, you can check the start of the string for their signatures to identify images, and assume you have JSON if it's not an image.

Another simple hack to identify a graphic, rather than a text string, in the case you're looking for a graphic, is just to test for non-ASCII characters in the first couple of dozen characters of the string (assuming the JSON is ASCII).

You can subtract the time zone difference from now.

final Calendar calendar  = Calendar.getInstance();
final int      utcOffset = calendar.get(Calendar.ZONE_OFFSET) + calendar.get(Calendar.DST_OFFSET);
final long     tempDate  = new Date().getTime();

return new Date(tempDate - utcOffset);

    mycon.value='';
    e.preventDefault();
  }
}

Push enter to 'send'<br>

Because the model that gets posted to the WebApi controller is detached from any entity-framework (EF) context, the only option is to load the object graph (parent including its children) from the database and compare which children have been added, deleted or updated. (Unless you would track the changes with your own tracking mechanism during the detached state (in the browser or wherever) which in my opinion is more complex than the following.) It could look like this:

public void Update(UpdateParentModel model)
{
    var existingParent = _dbContext.Parents
        .Where(p => p.Id == model.Id)
        .Include(p => p.Children)
        .SingleOrDefault();

    if (existingParent != null)
    {
        // Update parent
        _dbContext.Entry(existingParent).CurrentValues.SetValues(model);

        // Delete children
        foreach (var existingChild in existingParent.Children.ToList())
        {
            if (!model.Children.Any(c => c.Id == existingChild.Id))
                _dbContext.Children.Remove(existingChild);
        }

        // Update and Insert children
        foreach (var childModel in model.Children)
        {
            var existingChild = existingParent.Children
                .Where(c => c.Id == childModel.Id && c.Id != default(int))
                .SingleOrDefault();

            if (existingChild != null)
                // Update child
                _dbContext.Entry(existingChild).CurrentValues.SetValues(childModel);
            else
            {
                // Insert child
                var newChild = new Child
                {
                    Data = childModel.Data,
                    //...
                };
                existingParent.Children.Add(newChild);
            }
        }

        _dbContext.SaveChanges();
    }
}

...CurrentValues.SetValues can take any object and maps property values to the attached entity based on the property name. If the property names in your model are different from the names in the entity you can't use this method and must assign the values one by one.

Based on solution by Pavel Cerný here we can make an universal typed implementation of this pattern. To to it, we need to introduce NamedService interface:

    public interface NamedService {
       String name();
    }

and add abstract class:

public abstract class AbstractFactory<T extends NamedService> {

    private final Map<String, T> map;

    protected AbstractFactory(List<T> list) {
        this.map = list
                .stream()
                .collect(Collectors.toMap(NamedService::name, Function.identity()));
    }

    /**
     * Factory method for getting an appropriate implementation of a service
     * @param name name of service impl.
     * @return concrete service impl.

     */
    public T getInstance(@NonNull final String name) {
        T t = map.get(name);
        if(t == null)
            throw new RuntimeException("Unknown service name: " + name);
        return t;
    }
}

Then we create a concrete factory of specific objects like MyService:

 public interface MyService extends NamedService {
           String name();
           void doJob();
 }

@Component
public class MyServiceFactory extends AbstractFactory<MyService> {

    @Autowired
    protected MyServiceFactory(List<MyService> list) {
        super(list);
    }
}

where List the list of implementations of MyService interface at compile time.

This approach works fine if you have multiple similar factories across app that produce objects by name (if producing objects by a name suffice you business logic of course). Here map works good with String as a key, and holds all the existing implementations of your services.

if you have different logic for producing objects, this additional logic can be moved to some another place and work in combination with these factories (that get objects by name).

Use this function...

    #include<sstream>
    template <typename T>
    std::string to_string(T value)
    {
      //create an output string stream
      std::ostringstream os ;

      //throw the value into the string stream
      os << value ;

      //convert the string stream into a string and return
      return os.str() ;
    }

    //you can also do this
    //std::string output;
    //os >> output;  //throw whats in the string stream into the string

I recommend you to generate an open format XML Excel file, is much more flexible than CSV.

@Manish Jain, I suggest to implement the method with boolean return:

public class UserManager
{

    // Additional code here...            

    public async Task<bool> SignIn(HttpContext httpContext, UserDbModel user)
    {
        // Additional code here...            

        // Here the real authentication against a DB or Web Services or whatever 
        if (user.Email != null)
            return false;                    

        ClaimsIdentity identity = new ClaimsIdentity(this.GetUserClaims(dbUserData), CookieAuthenticationDefaults.AuthenticationScheme);
        ClaimsPrincipal principal = new ClaimsPrincipal(identity);

        // This is for give the authentication cookie to the user when authentication condition was met
        await httpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
        return true;
    }
}

in bash, you create array like this

arr=(one two three)

to call the elements

$ echo "${arr[0]}"
one
$ echo "${arr[2]}"
three

to ask for user input, you can use read

read -p "Enter your choice: " choice

A related question has been asked before: What is “above-the-fold content” in Google Pagespeed?

Firstly you have to notice that this is all about 'mobile pages'.
So when I interpreted your question and screenshot correctly, then this is not for your site!

On the contrary - doing some of the things advised by Google in their guidelines will things make worse than better for 'normal' websites.
And not everything that comes from Google is the "holy grail" just because it comes from Google. And they themselves are not a good role model if you have a look at their HTML markup.

The best advice I could give you is:

• Set width and height on replaced elements in your CSS, so that the browser can layout the elements and doesn't have to wait for the replaced content!

Additionally why do you use different CSS files, rather than just one?
The additional request is worse than the small amount of data volume. And after the first request the CSS file is cached anyway.

The things one should always take care of are:

• reduce the number of requests as much as possible
• keep your overall page weight as low as possible

And don't puzzle your brain about how to get 100% of Google's PageSpeed Insights tool ...! ;-)

Addition 1: Here is the page on which Google shows us, what they recommend for Optimize CSS Delivery.

As said before, I don't think that this is neither realistic nor that it makes sense for a "normal" website! Because mainly when you have a responsive web design it is most certain that you use media queries and other layout styles. So if you are not gonna load your CSS first and in a blocking manner you'll get a FOUT (Flash Of Unstyled Text). I really do not believe that this is "better" than at least some more milliseconds to render the page!

Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

This is how I implemented for my npm plugins

var monthNames = [
  "January", "February", "March",
  "April", "May", "June", "July",
  "August", "September", "October",
  "November", "December"
];

var Days = [
  "Sunday", "Monday", "Tuesday", "Wednesday",
  "Thursday", "Friday", "Saturday"
];

var formatDate = function(dt,format){
  format = format.replace('ss', pad(dt.getSeconds(),2));
  format = format.replace('s', dt.getSeconds());
  format = format.replace('dd', pad(dt.getDate(),2));
  format = format.replace('d', dt.getDate());
  format = format.replace('mm', pad(dt.getMinutes(),2));
  format = format.replace('m', dt.getMinutes());
  format = format.replace('MMMM', monthNames[dt.getMonth()]);
  format = format.replace('MMM', monthNames[dt.getMonth()].substring(0,3));
  format = format.replace('MM', pad(dt.getMonth()+1,2));
  format = format.replace(/M(?![ao])/, dt.getMonth()+1);
  format = format.replace('DD', Days[dt.getDay()]);
  format = format.replace(/D(?!e)/, Days[dt.getDay()].substring(0,3));
  format = format.replace('yyyy', dt.getFullYear());
  format = format.replace('YYYY', dt.getFullYear());
  format = format.replace('yy', (dt.getFullYear()+"").substring(2));
  format = format.replace('YY', (dt.getFullYear()+"").substring(2));
  format = format.replace('HH', pad(dt.getHours(),2));
  format = format.replace('H', dt.getHours());
  return format;
}

pad = function(n, width, z) {
  z = z || '0';
  n = n + '';
  return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}

I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding

style="position: relative; bottom: 0px"

to your Widget2 tag. Also try:

style="position: absolute; bottom: 0px"

if you want to snap your widget to the bottom of the screen.

I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.

Maybe someone will think of a clever way to do this, but you shouldn't. Swapping two items in a list is inherently side-effect laden but LINQ operations should be side-effect free. Thus, just use a simple extension method:

static class IListExtensions {
    public static void Swap<T>(
        this IList<T> list,
        int firstIndex,
        int secondIndex
    ) {
        Contract.Requires(list != null);
        Contract.Requires(firstIndex >= 0 && firstIndex < list.Count);
        Contract.Requires(secondIndex >= 0 && secondIndex < list.Count);
        if (firstIndex == secondIndex) {
            return;
        }
        T temp = list[firstIndex];
        list[firstIndex] = list[secondIndex];
        list[secondIndex] = temp;
    }
}

I was curious as to how the speed of the numpy answer performed against the other answers since this was left out of the comparisons. To generate one random bool this is much slower but if you wanted to generate many then this becomes much faster:

$ python -m timeit -s "from random import random" "random() < 0.5"
10000000 loops, best of 3: 0.0906 usec per loop
$ python -m timeit -s "import numpy as np" "np.random.randint(2, size=1)"
100000 loops, best of 3: 4.65 usec per loop

$ python -m timeit -s "from random import random" "test = [random() < 0.5 for i in range(1000000)]"
10 loops, best of 3: 118 msec per loop
$ python -m timeit -s "import numpy as np" "test = np.random.randint(2, size=1000000)"
100 loops, best of 3: 6.31 msec per loop

BootFlat

You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:

The CSS Lists and Counters Module Level 3 introduces the ::marker pseudo-element. From what I've understood it would allow such a thing. Unfortunately, no browser seems to support it.

What you can do is add some padding to the parent ul and pull the icon into that padding:

ul {_x000D_
  list-style: none;_x000D_
  padding: 0;_x000D_
}_x000D_
li {_x000D_
  padding-left: 1.3em;_x000D_
}_x000D_
li:before {_x000D_
  content: "\f00c"; /* FontAwesome Unicode */_x000D_
  font-family: FontAwesome;_x000D_
  display: inline-block;_x000D_
  margin-left: -1.3em; /* same as padding-left set on li */_x000D_
  width: 1.3em; /* same as padding-left set on li */_x000D_
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">_x000D_
<ul>_x000D_
  <li>Item one</li>_x000D_
  <li>Item two</li>_x000D_
</ul>

Adjust the padding/font-size/etc to your liking, and that's it. Here's the usual fiddle: http://jsfiddle.net/joplomacedo/a8GxZ/

=====

This works with any type of iconic font. FontAwesome, however, provides their own way to deal with this 'problem'. Check out Darrrrrren's answer below for more details.

First, you need to allocate array of pointers like char **c = malloc( N * sizeof( char* )), then allocate each row with a separate call to malloc, probably in the loop:

/* N is the number of rows  */
/* note: c is char** */
if (( c = malloc( N*sizeof( char* ))) == NULL )
{ /* error */ }

for ( i = 0; i < N; i++ )
{
  /* x_i here is the size of given row, no need to
   * multiply by sizeof( char ), it's always 1
   */
  if (( c[i] = malloc( x_i )) == NULL )
  { /* error */ }

  /* probably init the row here */
}

/* access matrix elements: c[i] give you a pointer
 * to the row array, c[i][j] indexes an element
 */
c[i][j] = 'a';

If you know the total number of elements (e.g. N*M) you can do this in a single allocation.

contentType is the type of data you're sending, so application/json; charset=utf-8 is a common one, as is application/x-www-form-urlencoded; charset=UTF-8, which is the default.

dataType is what you're expecting back from the server: json, html, text, etc. jQuery will use this to figure out how to populate the success function's parameter.

If you're posting something like:

{"name":"John Doe"}

and expecting back:

{"success":true}

Then you should have:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "json",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        alert(result.success); // result is an object which is created from the returned JSON
    },
});

If you're expecting the following:

<div>SUCCESS!!!</div>

Then you should do:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "html",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

One more - if you want to post:

name=John&age=34

Then don't stringify the data, and do:

var data = {"name":"John", "age": 34}
$.ajax({
    dataType : "html",
    contentType: "application/x-www-form-urlencoded; charset=UTF-8", // this is the default value, so it's optional
    data : data,
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

max=int(input("Find primes upto what numbers?"))
primeList=[]
for x in range(2,max+1):
    isPrime=True
    for y in range(2,int(x**0.5)+1) :
        if x%y==0:
            isPrime=False
            break

    if isPrime:
        primeList.append(x)
print(primeList)

Finally, I found a solution to know if the current item is visible, from the onBindViewHolder event in the adapter.

The key is the method isViewPartiallyVisible from LayoutManager.

In your adapter, you can get the LayoutManager from the RecyclerView, which you get as parameter from the onAttachedToRecyclerView event.

You can create new User library,

On

"Configure Build Paths" page -> Add Library -> User Library (on list) -> User Libraries Button (rigth side of page)

and create your library and (add Jars buttons) include your specific Jars.

I hope this can help you.

After searching a lot I find out that it is possible to create a new folder from the web interface, but it would require you to have at least one file within the folder when creating it.

When using the normal way of creating new files through the web interface, you can type in the folder into the file name to create the file within that new directory.

For example, if I would like to create the file filename.md in a series of sub-folders, I can do this (taken from the GitHub blog):

How About

int myInt = 88;

// Will not compile

Long myLong = myInt;

// Compiles, and retains the non-NULL spirit of int. The best cast is no cast at all. Of course, your use case may require Long and possible NULL values. But if the int, or other longs are your only input, and your method can be modified, I would suggest this approach.

long myLong = myInt;

// Compiles, is the most efficient way, and makes it clear that the source value, is and will never be NULL.

Long myLong = (long) myInt;

I am having MAC OS X(Sierra) 10.12.2.

I set JAVA_HOME to work on React Native(for Android apps) by following the following steps.

• Open Terminal (Command+R, type Terminal, Hit ENTER).

• Add the following lines to ~/.bash_profile. export JAVA_HOME=$(/usr/libexec/java_home)

• Now run the following command. source ~/.bash_profile

• You can check the exact value of JAVA_HOME by typing the following command. echo $JAVA_HOME

The value(output) returned will be something like below. /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

That's it.

Run below command where pom.xml is placed:

mvn spring-boot:run -Drun.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

And start your remote java application with debugging option on port 5005

For deep nested object you can use my snippet for lodash > 4

const removeObjectsWithNull = (obj) => {
    return _(obj)
      .pickBy(_.isObject) // get only objects
      .mapValues(removeObjectsWithNull) // call only for values as objects
      .assign(_.omitBy(obj, _.isObject)) // save back result that is not object
      .omitBy(_.isNil) // remove null and undefined from object
      .value(); // get value
};

This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):

It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.

Here are the commands again for easier copy-pasting:

openssl rsa                                                -in $FF -out $TF

and
