If you are happy to use a 3rd party library, you can do this with Pandas. The benefits include seamless access to specialized methods and row / column labeling:

import pandas as pd

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]

df = pd.DataFrame(list(zip(*[list1, list2, list3]))).add_prefix('Col')

df.to_csv('file.csv', index=False)

print(df)

   Col0  Col1  Col2
0     1     4     7
1     2     5     8
2     3     6     9

Python 3.x

from copy import deepcopy

my_dict = {'one': 1, 'two': 2}
new_dict_deepcopy = deepcopy(my_dict)

Without deepcopy, I am unable to remove the hostname dictionary from within my domain dictionary.

Without deepcopy I get the following error:

"RuntimeError: dictionary changed size during iteration"

...when I try to remove the desired element from my dictionary inside of another dictionary.

import socket
import xml.etree.ElementTree as ET
from copy import deepcopy

domain is a dictionary object

def remove_hostname(domain, hostname):
    domain_copy = deepcopy(domain)
    for domains, hosts in domain_copy.items():
        for host, port in hosts.items():
           if host == hostname:
                del domain[domains][host]
    return domain

Example output: [orginal]domains = {'localdomain': {'localhost': {'all': '4000'}}}

[new]domains = {'localdomain': {} }}

So what's going on here is I am iterating over a copy of a dictionary rather than iterating over the dictionary itself. With this method, you are able to remove elements as needed.

Question 1 query:

SELECT ta.C1
      ,ta.C2
      ,ta.C3
      ,ta.C4
FROM [TableA] ta
WHERE (SELECT COUNT(*)
       FROM [TableA] ta2
       WHERE ta.C2=ta2.C2
       AND ta.C3=ta2.C3
       AND ta.C4=ta2.C4)>1

The error you gave is due to the fact that in python, dictionary keys must be immutable types (if key can change, there will be problems), and list is a mutable type.

Your error says that you try to use a list as dictionary key, you'll have to change your list into tuples if you want to put them as keys in your dictionary.

According to the python doc :

The only types of values not acceptable as keys are values containing lists or dictionaries or other mutable types that are compared by value rather than by object identity, the reason being that the efficient implementation of dictionaries requires a key’s hash value to remain constant

Mongodb and Mongoose are two different drivers to interact with MongoDB database.

Mongoose : object data modeling (ODM) library that provides a rigorous modeling environment for your data. Used to interact with MongoDB, it makes life easier by providing convenience in managing data.

Mongodb: native driver in Node.js to interact with MongoDB.

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

.a files are usually libraries which get statically linked (or more accurately archives), and
.so are dynamically linked libraries.

To do a port you will need the source code that was compiled to make them, or equivalent files on your AIX machine.

If you're using latest cross platform powershell (which you should btw) https://github.com/powershell/powershell#get-powershell, you can add single & to run parallel scripts. (Use ; to run sequentially)

In my case I needed to run 2 npm scripts in parallel: npm run hotReload & npm run dev

You can also setup npm to use powershell for its scripts (by default it uses cmd on windows).

Run from project root folder: npm config set script-shell pwsh --userconfig ./.npmrc and then use single npm script command: npm run start

"start":"npm run hotReload & npm run dev"

To display the item number on the repeater you can use the Container.ItemIndex property.

<asp:repeater id="rptRepeater" runat="server">
    <itemtemplate>
        Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
    </itemtemplate>
    <separatortemplate>
        <br />
    </separatortemplate>
</asp:repeater>

How easy :)

date("F j, Y", strtotime( '-1 days' ) );

Example:

echo date("Y-m-j H:i:s", strtotime( '-1 days' ) ); // 2018-07-18 07:02:43

Output:

2018-07-17 07:02:43

I would like to add to Narm's answer here and have added the same as a comment under her answer.

Basically the datatype of the value assigned to [(value)] should match the datatype of the [value] attribute used for the mat-options. Especially if some one populates the options using an *ngFor as below

<mat-form-field fxHide.gt-sm='true'>
        <mat-select [(value)]="heroes[0].id">
          <mat-option *ngFor="let hero of heroes" [value]="hero.id">{{ hero.name }}</mat-option>
        </mat-select>
</mat-form-field>

Notice that, if you change the [(value)]="heroes[0].id" to [(value)]="heroes[0].name" it won't work as the data types don't match.

These are my findings, please feel free to correct me if needed.

@James Jithin - such exception can appear also when you have two different versions of beans and security schema in xsi:schemaLocation. It's the case in the snippet you have pasted:

xsi:schemaLocation="http://www.springframework.org/schema/beans   
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
 http://www.springframework.org/schema/security  
 http://www.springframework.org/schema/security/spring-security-3.1.xsd"

In my case changing them both to 3.1 solved the problem

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

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

Using Python will be one easy way to achieve what you want.

I found one using Google.

"convert from json to csv using python" is an example.

https://www.kaggle.com/jboysen/quick-gz-pandas-tutorial

Please follow this link.

import pandas as pd
traffic_station_df = pd.read_csv('C:\\Folders\\Jupiter_Feed.txt.gz', compression='gzip',
                                 header=1, sep='\t', quotechar='"')

#traffic_station_df['Address'] = 'address'

#traffic_station_df.append(traffic_station_df)
print(traffic_station_df)

use NumpyEncoder it will process json dump successfully.without throwing - NumPy array is not JSON serializable

import numpy as np
import json
from numpyencoder import NumpyEncoder
arr = array([   0,  239,  479,  717,  952, 1192, 1432, 1667], dtype=int64) 
json.dumps(arr,cls=NumpyEncoder)

Surely you just need:

double seconds = milliseconds / 1000.0;

There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0 (as a double literal) forces. (I'm assuming your milliseconds value is an integer of some form.)

Note that as usual with double, you may not be able to represent the result exactly. Consider using BigDecimal if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double is probably appropriate, but...)

THIS ANSWER IS FOR ANIMATIONS ONLY


If you wanna implement the AND logic, you should use MultiTrigger, here is an example:

Suppose we want to do some actions if the property Text="" (empty string) AND IsKeyboardFocused="False", then your code should look like the following:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
        <MultiTrigger.EnterActions>
            <!-- Your actions here -->
        </MultiTrigger.EnterActions>
</MultiTrigger>

If you wanna implement the OR logic, there are couple of ways, and it depends on what you try to do:

The first option is to use multiple Triggers.
So, suppose you wanna do something if either Text="" OR IsKeyboardFocused="False",
then your code should look something like this:

<Trigger Property="IsEnabled" Value="false">
    <Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
    <Setter Property="BorderBrush" TargetName="border" 
            Value="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>

But the problem in this is what will I do if i wanna do something if either Text ISN'T null OR IsKeyboard="True"? This can be achieved by the second approach:
Recall De Morgan's rule, that says !(!x && !y) = x || y.
So we'll use it to solve the previous problem, by writing a multi trigger that it's triggered when Text="" and IsKeyboard="True", and we'll do our actions in EXIT ACTIONS, like this:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
    <MultiTrigger.ExitActions>
        <!-- Do something here -->
    </MultiTrigger.ExitActions>
</MultiTrigger>

Faster way of writing it would be...

in = open('path/to/input/file').read()
out = open('path/to/input/file', 'w')
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for i in replacements.keys():
    in = in.replace(i, replacements[i])
out.write(in)
out.close

This eliminated a lot of the iterations that the other answers suggest, and will speed up the process for longer files.

But, sometimes, even with user-select and touch-callout turned off, cursor: pointer; may cause this effect, so, just set cursor: default; and it'll work.

You need to add

#container
{
    display:inline-block;
    position:relative;
    background:rgb(255,100,0);
    margin:0px;
    width:40%;
    height:100px;
    margin-right:-4px;
}

because whenever you write display:inline-block it takes an additional margin-right:4px. So, you need to remove it.

I had Win 8 x86 installed. My Path variable had entry C:\Program Files\Java\jdk1.6.0_31\bin and I also had following variables:

• JAVA_HOME : C:\Program Files\Java\jdk1.6.0_31;
• JRE_HOME : C:\Program Files\Java\jre6;

My tomcat is installed at C:\Program Files\Apache Software Foundation\apache-tomcat-7.0.41

And still it did not worked for me.

I tried by replacing Program Files in those paths with Progra~1. I also tried by moving JAVA to another folder so that full path to it does not contain any spaces. But nothing worked.

Finally environment variables that worked for me are:

• Kept path variable as is with full Program Files i.e. C:\Program Files\Java\jdk1.6.0_31\bin
• JAVA_HOME : C:\Program Files\Java\jdk1.6.0_31
• Deleted JRE_HOME

So what I did is removed JRE_HOME and removed semicolon at the end of JAVA_HOME. I think semicolon should not be an issue, though I removed it. I am giving these settings, since after a lot of googling nothing worked for me and suddenly these seem to work. You can replicate and see if it works for you.

This also worked for Win 7 x64, where

• Path variable contained C:\Program Files (x86)\Java\jdk1.7.0_17\bin
• JAVA_HOME is set to C:\Program Files (x86)\Java\jdk1.7.0_17 (without semicoln)

Please tell me why this worked, I know removing JRE_HOME was weird solution, but any guesses what difference it makes?

You can add a sequence of numbers very easily with

data$ID <- seq.int(nrow(data))

If you are already using library(tidyverse), you can use

data <- tibble::rowid_to_column(data, "ID")

Besides installing the required packages, I also needed to manually add PostgreSQL bin directory to PATH.
$vi ~/.bash_profile
Add PATH=/usr/pgsql-9.2/bin:$PATH before export PATH.
$source ~/.bash_profile
$pip install psycopg2

variable=10
f=open("fileName.txt","w+") # file name and mode
for x in range(0,10):
    f.writelines('your text')
    f.writelines('if you want to add variable data'+str(variable))
    # to add data you only add String data so you want to type cast variable  
    f.writelines("\n")

Datatype 'bigint unsigned' may suit this requirement.

You should be able to download the file using

window.open("data:application/pdf;base64," + Base64.encode(out));

From the firebug site http://getfirebug.com/logging/

Calling console.dir(object) will log an interactive listing of an object's properties, like > a miniature version of the DOM tab.

(inline if) in java won't work if you are using 'if' statement .. the right syntax is in the following example:

int y = (c == 19) ? 7 : 11 ; 

or

String y = (s > 120) ? "Slow Down" : "Safe";
System.out.println(y);

as You can see the type of the variable Y is the same as the return value ...

in your case it is better to use the normal if statement not inline if as it is in the pervious answer without "?"

if (compareChar(curChar, toChar("0"))) getButtons().get(i).setText("§");

I have the feeling that the check should be different

new: h < 768 || w < 1024

I ran this on MacOS /Applications/Python\ 3.6/Install\ Certificates.command

The tersest expressive code to find the minimum value is probably rest parameters:

const arr = [14, 58, 20, 77, 66, 82, 42, 67, 42, 4]_x000D_
const min = Math.min(...arr)_x000D_
console.log(min)

Rest parameters are essentially a convenient shorthand for Function.prototype.apply when you don't need to change the function's context:

var arr = [14, 58, 20, 77, 66, 82, 42, 67, 42, 4]_x000D_
var min = Math.min.apply(Math, arr)_x000D_
console.log(min)

This is also a great use case for Array.prototype.reduce:

const arr = [14, 58, 20, 77, 66, 82, 42, 67, 42, 4]_x000D_
const min = arr.reduce((a, b) => Math.min(a, b))_x000D_
console.log(min)

It may be tempting to pass Math.min directly to reduce, however the callback receives additional parameters:

callback (accumulator, currentValue, currentIndex, array)

In this particular case it may be a bit verbose. reduce is particularly useful when you have a collection of complex data that you want to aggregate into a single value:

const arr = [{name: 'Location 1', distance: 14}, {name: 'Location 2', distance: 58}, {name: 'Location 3', distance: 20}, {name: 'Location 4', distance: 77}, {name: 'Location 5', distance: 66}, {name: 'Location 6', distance: 82}, {name: 'Location 7', distance: 42}, {name: 'Location 8', distance: 67}, {name: 'Location 9', distance: 42}, {name: 'Location 10', distance: 4}]_x000D_
const closest = arr.reduce(_x000D_
  (acc, loc) =>_x000D_
    acc.distance < loc.distance_x000D_
      ? acc_x000D_
      : loc_x000D_
)_x000D_
console.log(closest)

And of course you can always use classic iteration:

var arr,_x000D_
  i,_x000D_
  l,_x000D_
  min_x000D_
_x000D_
arr = [14, 58, 20, 77, 66, 82, 42, 67, 42, 4]_x000D_
min = Number.POSITIVE_INFINITY_x000D_
for (i = 0, l = arr.length; i < l; i++) {_x000D_
  min = Math.min(min, arr[i])_x000D_
}_x000D_
console.log(min)

...but even classic iteration can get a modern makeover:

const arr = [14, 58, 20, 77, 66, 82, 42, 67, 42, 4]_x000D_
let min = Number.POSITIVE_INFINITY_x000D_
for (const value of arr) {_x000D_
  min = Math.min(min, value)_x000D_
}_x000D_
console.log(min)

you can also use the full filename to your gem file:

gem install /full/path/to/your.gem

this works as well -- it's probably the easiest way

Update: Apparently possible by passing a flag to mysql_connect(). See Executing multiple SQL queries in one statement with PHP Nevertheless, any current reader should avoid using the mysql_-class of functions and prefer PDO.

You can't do that using the regular mysql-api in PHP. Just execute two queries. The second one will be so fast that it won't matter. This is a typical example of micro optimization. Don't worry about it.

For the record, it can be done using mysqli and the mysqli_multi_query-function.

Another addition: be careful when replacing multiples and converting the type of the column back from object to float. If you want to be certain that your None's won't flip back to np.NaN's apply @andy-hayden's suggestion with using pd.where. Illustration of how replace can still go 'wrong':

In [1]: import pandas as pd

In [2]: import numpy as np

In [3]: df = pd.DataFrame({"a": [1, np.NAN, np.inf]})

In [4]: df
Out[4]:
     a
0  1.0
1  NaN
2  inf

In [5]: df.replace({np.NAN: None})
Out[5]:
      a
0     1
1  None
2   inf

In [6]: df.replace({np.NAN: None, np.inf: None})
Out[6]:
     a
0  1.0
1  NaN
2  NaN

In [7]: df.where((pd.notnull(df)), None).replace({np.inf: None})
Out[7]:
     a
0  1.0
1  NaN
2  NaN

We just released preview driver for Node.JS for SQL Server connectivity. You can find it here: Introducing the Microsoft Driver for Node.JS for SQL Server.

The driver supports callbacks (here, we're connecting to a local SQL Server instance):

// Query with explicit connection
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server=(local);Database=AdventureWorks2012;Trusted_Connection={Yes}";

sql.open(conn_str, function (err, conn) {
    if (err) {
        console.log("Error opening the connection!");
        return;
    }
    conn.queryRaw("SELECT TOP 10 FirstName, LastName FROM Person.Person", function (err, results) {
        if (err) {
            console.log("Error running query!");
            return;
        }
        for (var i = 0; i < results.rows.length; i++) {
            console.log("FirstName: " + results.rows[i][0] + " LastName: " + results.rows[i][1]);
        }
    });
});

Alternatively, you can use events (here, we're connecting to SQL Azure a.k.a Windows Azure SQL Database):

// Query with streaming
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server={tcp:servername.database.windows.net,1433};UID={username};PWD={Password1};Encrypt={Yes};Database={databasename}";

var stmt = sql.query(conn_str, "SELECT FirstName, LastName FROM Person.Person ORDER BY LastName OFFSET 0 ROWS FETCH NEXT 10 ROWS ONLY");
stmt.on('meta', function (meta) { console.log("We've received the metadata"); });
stmt.on('row', function (idx) { console.log("We've started receiving a row"); });
stmt.on('column', function (idx, data, more) { console.log(idx + ":" + data);});
stmt.on('done', function () { console.log("All done!"); });
stmt.on('error', function (err) { console.log("We had an error :-( " + err); });

If you run into any problems, please file an issue on Github: https://github.com/windowsazure/node-sqlserver/issues

OVERVIEW

I have written a simple semantic hack for this using @AshutoshMehraresponse. You code looks really readable this way!

MACRO

#include <time.h>

#ifndef SYSOUT_F
#define SYSOUT_F(f, ...)      _RPT1( 0, f, __VA_ARGS__ ) // For Visual studio
#endif

#ifndef speedtest__             
#define speedtest__(data)   for (long blockTime = NULL; (blockTime == NULL ? (blockTime = clock()) != NULL : false); SYSOUT_F(data "%.9fs", (double) (clock() - blockTime) / CLOCKS_PER_SEC))
#endif

USAGE

speedtest__("Block Speed: ")
{
    // The code goes here
}

OUTPUT

Block Speed: 0.127000000s

I faced similar error, tried all the suggestions above, but did not resolve. what worked for me is this:

Right-click your Global.asax file and click View Markup. You will see the attribute Inherits="nadeem.MvcApplication". This means that your Global.asax file is trying to inherit from the type nadeem.MvcApplication.

Now double click your Global.asax file and see what the class name specified in your Global.asax.cs file is. It should look something like this:

namespace nadeem
{

public class MvcApplication: System.Web.HttpApplication
    {
    ....

But if it doesn't look like above, you will receive that error, The value in the Inherits attribute of your Global.asax file must match a type that is derived from System.Web.HttpApplication.

Check below link for more info:

Parser Error: Server Error in '/' Application

System.out.println(Integer.toHexString(test[0]));

OR (pretty print)

System.out.printf("0x%02X", test[0]);

OR (pretty print)

System.out.println(String.format("0x%02X", test[0]));

Please find in the below code what I developed to support internationalization. It formats the given numeric value to language specific format. In the given example I have used ‘en’ while have tested for ‘es’, ‘fr’ and other countries where in the format varies. It not only stops user from keying characters but formats the value on tab out. Have created components for Number as well as for Decimal format. Apart from this have created parseNumber(value, locale) and parseDecimal(value, locale) functions which will parse the formatted data for any other business purposes. The said function will accept the formatted data and will return the non-formatted value. I have used JQuery validator plugin in the below shared code.

        if (value.toString().substring(
                0, value.toString().lastIndexOf('.')).length > numericMaxLimit
                || value.toString().length > decimalMaxLimit) {
            setFocus(id);
            return true;
        }
        return false;
    };

Here is example which can give you some hints to iterate through existing array and add items to new array. I use UnderscoreJS Module to use as my utility file.

You can download from (https://npmjs.org/package/underscore)

$ npm install underscore

Here is small snippet to demonstrate how you can do it.

var _ = require("underscore");
var calendars = [1, "String", {}, 1.1, true],
    newArray = [];

_.each(calendars, function (item, index) {
    newArray.push(item);
});

console.log(newArray);

Gradle 4.9+

gradle run --args='arg1 arg2'

This assumes your build.gradle is configured with the Application plugin. Your build.gradle should look similar to this:

plugins {
  // Implicitly applies Java plugin
  id: 'application'
}

application {
  // URI of your main class/application's entry point (required)
  mainClassName = 'org.gradle.sample.Main'
}

Pre-Gradle 4.9

Include the following in your build.gradle:

run {
    if (project.hasProperty("appArgs")) {
        args Eval.me(appArgs)
    }
}

Then to run: gradle run -PappArgs="['arg1', 'args2']"

Each version of Visual Studio prior to Visual Studio 2010 is tied to a specific .NET framework. (VS2008 is .NET 3.5, VS2005 is .NET 2.0, VS2003 is .NET1.1) Visual Studio 2010 and beyond allow for targeting of prior framework versions but cannot be used for future releases. You must use Visual Studio 2012 in order to utilize .NET 4.5.

Use the replace() method on string:

>>> stuff = "Big and small"
>>> stuff.replace( " and ", "/" )
'Big/small'

Add the s modifier to your regex to cause . to match newlines:

$string =~ /(START)(.+?)(END)/s;

CASE and CAST should work:

CASE WHEN mycol IS NULL THEN '' ELSE CONVERT(varchar(50), mycol, 121) END

if the data is already valid and already contains a pdf, word or image, then you could use a StreamWriter and save it.

You can easily catch integer(0) with function identical(x,y)

x = integer(0)
identical(x, integer(0))
[1] TRUE

foo = function(x){identical(x, integer(0))}
foo(x)
[1] TRUE

foo(0)
[1] FALSE

Your question doesn't address what you want to put in the DIV tags, which is probably why you've received some incomplete/wrong answers. The truth is that you can, as Royi said, put DIV tags inside of your forms. You don't want to do this for labels, for instance, but if you have a form with a bunch of checkboxes that you want to lay out into three columns, then by all means, use DIV tags (or SPAN, HEADER, etc.) to accomplish the look and feel you're trying to achieve.

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

When you create your own key pair object, you should face a few thing.

First, you should be aware of implementing hashCode() and equals(). You will need to do this.

Second, when implementing hashCode(), make sure you understand how it works. The given user example

public int hashCode() {
    return this.x ^ this.y;
}

is actually one of the worst implementations you can do. The reason is simple: you have a lot of equal hashes! And the hashCode() should return int values that tend to be rare, unique at it's best. Use something like this:

public int hashCode() {
  return (X << 16) + Y;
}

This is fast and returns unique hashes for keys between -2^16 and 2^16-1 (-65536 to 65535). This fits in almost any case. Very rarely you are out of this bounds.

Third, when implementing equals() also know what it is used for and be aware of how you create your keys, since they are objects. Often you do unnecessary if statements cause you will always have the same result.

If you create keys like this: map.put(new Key(x,y),V); you will never compare the references of your keys. Cause everytime you want to acces the map, you will do something like map.get(new Key(x,y));. Therefore your equals() does not need a statement like if (this == obj). It will never occure.

Instead of if (getClass() != obj.getClass()) in your equals() better use if (!(obj instanceof this)). It will be valid even for subclasses.

So the only thing you need to compare is actually X and Y. So the best equals() implementation in this case would be:

public boolean equals (final Object O) {
  if (!(O instanceof Key)) return false;
  if (((Key) O).X != X) return false;
  if (((Key) O).Y != Y) return false;
  return true;
}

So in the end your key class is like this:

public class Key {

  public final int X;
  public final int Y;

  public Key(final int X, final int Y) {
    this.X = X;
    this.Y = Y;
  }

  public boolean equals (final Object O) {
    if (!(O instanceof Key)) return false;
    if (((Key) O).X != X) return false;
    if (((Key) O).Y != Y) return false;
    return true;
  }

  public int hashCode() {
    return (X << 16) + Y;
  }

}

You can give your dimension indices X and Y a public access level, due to the fact they are final and do not contain sensitive information. I'm not a 100% sure whether private access level works correctly in any case when casting the Object to a Key.

If you wonder about the finals, I declare anything as final which value is set on instancing and never changes - and therefore is an object constant.

You can use http_response_code() to set HTTP response code.

If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code.

http_response_code(201); // Set response status code to 201

For Laravel(Reference from: https://stackoverflow.com/a/14717895/2025923):

return Response::json([
    'hello' => $value
], 201); // Status code here

You can bind resize using .resize() and run your code when the browser is resized. You need to also add an else condition to your if statement so that your css values toggle the old and the new, rather than just setting the new.

Try this:

function addClass(element, value) {
  if(!element.className) {
    element.className = value;
  } else {
    newClassName = element.className;
    newClassName+= " ";
    newClassName+= value;
    element.className = newClassName;
  }
}

Similar logic could be used to make a removeClass function.

Try using the ISO string

var isodate = new Date().toISOString()

See also: method definition at MDN.

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

$model = Mage::getModel('catalog/product'); //getting product model
$_products = $model->getCollection(); //getting product object for particular product id
foreach($_products as $_product) { ?>
    <a href = '<?php echo $model->load($_product->getData("entity_id"))->getUrl_path(); ?>'> <img src= '<?php echo $model->load($_product->getData("entity_id"))->getImageUrl();  ?>' width="75px" height="75px"/></a>
     <?php echo "<br/>".$model->load($_product->getData("entity_id"))->getPrice()."<br/>". $model->load($_product->getData("entity_id"))->getSpecial_price()."<br/>".$model->load($_product->getData("entity_id"))->getName()?>
<?php 

Modernized and slightly modified version of the extension methods for ToStream:

public static Stream ToStream(this string value) => ToStream(value, Encoding.UTF8);

public static Stream ToStream(this string value, Encoding encoding) 
                          => new MemoryStream(encoding.GetBytes(value ?? string.Empty));

Modification as suggested in @Palec's comment of @Shaun Bowe answer.

In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.

import os

path = chap_name

if not os.path.exists(path):
    os.makedirs(path)

filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
    temp_file.write(buff)

Key point is to use os.makedirs in place of os.mkdir. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html

Open the file in binary mode as you are storing binary (jpeg) data.

In response to Edit 2, if img_alt sometimes has '/' in it:

img_alt = os.path.basename(img_alt)

You can use the below code to run test cases in Chrome using Selenium WebDriver:

import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class ChromeTest {

    /**
     * @param args
     * @throws InterruptedException
     * @throws IOException
     */
    public static void main(String[] args) throws InterruptedException, IOException {
        // Telling the system where to find the Chrome driver
        System.setProperty(
                "webdriver.chrome.driver",
                "E:/chromedriver_win32/chromedriver.exe");

        WebDriver webDriver = new ChromeDriver();

        // Open google.com
        webDriver.navigate().to("http://www.google.com");

        String html = webDriver.getPageSource();

        // Printing result here.
        System.out.println(html);

        webDriver.close();
        webDriver.quit();
    }
}

as your service is already setup, simply add a broadcast receiver in your service:

private final BroadcastReceiver receiver = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
      String action = intent.getAction();
      if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
        //action for sms received
      }
      else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
           //action for phone state changed
      }     
   }
};

in your service's onCreate do this:

IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
filter.addAction("your_action_strings"); //further more
filter.addAction("your_action_strings"); //further more

registerReceiver(receiver, filter);

and in your service's onDestroy:

unregisterReceiver(receiver);

and you are good to go to receive broadcast for what ever filters you mention in onCreate. Make sure to add any permission if required. for e.g.

<uses-permission android:name="android.permission.RECEIVE_SMS" />

As asked for by @??s???? an explanation can be found at https://golang.org/pkg/fmt/#Sprint. Related explanations can be found at https://stackoverflow.com/a/44027953/12817546 and at https://stackoverflow.com/a/42302709/12817546. Here is @Yuanbo's answer in full.

package main

import "fmt"

func main() {
    var data interface{} = 2
    str := fmt.Sprint(data)
    fmt.Println(str)
}

you can also introspect all HTTP traffic running over your tunnels using ngrok , then you can expose using ngrok http --host-header=rewrite 4200

import requests

url = requests.get("http://yahoo.com")
htmltext = url.text
print(htmltext)

This will work similar to urllib.urlopen.

header files contain prototypes for functions you define in a .c or .cpp/.cxx file (depending if you're using c or c++). You want to place #ifndef/#defines around your .h code so that if you include the same .h twice in different parts of your programs, the prototypes are only included once.

client.h

#ifndef CLIENT_H
#define CLIENT_H

short socketConnect(char *host,unsigned short port,char *sendbuf,char *recievebuf, long rbufsize);


#endif /** CLIENT_H */

Then you'd implement the .h in a .c file like so:

client.c

#include "client.h"

short socketConnect(char *host,unsigned short port,char *sendbuf,char *recievebuf, long rbufsize) {
 short ret = -1;
 //some implementation here
 return ret;
}

You can use the synchronizedCollection/List method in java.util.Collection to get a thread-safe collection from a non-thread-safe one.

Since you cannot do this:

obj.prop = 'value';

If your TS compiler and your linter does not strict you, you can write this:

obj['prop'] = 'value';

If your TS compiler or linter is strict, another answer would be to typecast:

var obj = {};
obj = obj as unknown as { prop: string };
obj.prop = "value";

What Chad says, except its better to use .keyup in this case because with .keydown and .keypress the value of the input is still the older value i.e. the newest key pressed would not be reflected if .val() is called.

This should probably be a comment on Chad's answer but I dont have privileges to comment yet.

You should use:

dir.Delete(true);

for recursively deleting the contents of that folder too. See MSDN DirectoryInfo.Delete() overloads.

This snippet might help in removing the xticks only.

Well 'Abstract Interface' is a Lexical construct: http://en.wikipedia.org/wiki/Lexical_analysis.

It is required by the compiler, you could also write interface.

Well don't get too much into Lexical construct of the language as they might have put it there to resolve some compilation ambiguity which is termed as special cases during compiling process or for some backward compatibility, try to focus on core Lexical construct.

The essence of `interface is to capture some abstract concept (idea/thought/higher order thinking etc) whose implementation may vary ... that is, there may be multiple implementation.

An Interface is a pure abstract data type that represents the features of the Object it is capturing or representing.

Features can be represented by space or by time. When they are represented by space (memory storage) it means that your concrete class will implement a field and method/methods that will operate on that field or by time which means that the task of implementing the feature is purely computational (requires more cpu clocks for processing) so you have a trade off between space and time for feature implementation.

If your concrete class does not implement all features it again becomes abstract because you have a implementation of your thought or idea or abstractness but it is not complete , you specify it by abstract class.

A concrete class will be a class/set of classes which will fully capture the abstractness you are trying to capture class XYZ.

So the Pattern is

Interface--->Abstract class/Abstract classes(depends)-->Concrete class

Yes for some reason WebView.reload() causes a crash if it failed to load before (something to do with the way it handles history). This is the code I use to refresh my webview. I store the current url in self.url

# 1: Pause timeout and page loading

self.timeout.pause()
sleep(1)

# 2: Check for internet connection (Really lazy way)

while self.page().networkAccessManager().networkAccessible() == QNetworkAccessManager.NotAccessible: sleep(2)

# 3:Try again

if self.url == self.page().mainFrame().url():
    self.page().action(QWebPage.Reload)
    self.timeout.resume(60)

else:
    self.page().action(QWebPage.Stop)
    self.page().mainFrame().load(self.url)
    self.timeout.resume(30)

return False

I did not see anything in my path related to HTC Sync Manager, though I had it installed. I'm not working with my HTC device at the moment, and only had the sync manager installed to help with driver issues. Once uninstalling the HTC sync manager this issue went away for me.

Hope this helps someone else.

File descriptors are nothing but references for any open resource. As soon as you open a resource the kernel assumes you will be doing some operations on it. All the communication via your program and the resource happens over an interface and this interface is provided by the file-descriptor.

Since a process can open more than one resource, it is possible for a resource to have more than one file-descriptors.
You can view all file-descriptors linked to the process by simply running, ls -li /proc/<pid>/fd/ here pid is the process-id of your process

I realize this is years late, but I thought I could expand on Conor's answer and add a little bit more to the discussion.

Can someone give me a step by step description of how cookie based authentication works? I've never done anything involving either authentication or cookies. What does the browser need to do? What does the server need to do? In what order? How do we keep things secure?

Step 1: Client > Signing up

Before anything else, the user has to sign up. The client posts a HTTP request to the server containing his/her username and password.

Step 2: Server > Handling sign up

The server receives this request and hashes the password before storing the username and password in your database. This way, if someone gains access to your database they won't see your users' actual passwords.

Step 3: Client > User login

Now your user logs in. He/she provides their username/password and again, this is posted as a HTTP request to the server.

Step 4: Server > Validating login

The server looks up the username in the database, hashes the supplied login password, and compares it to the previously hashed password in the database. If it doesn't check out, we may deny them access by sending a 401 status code and ending the request.

Step 5: Server > Generating access token

If everything checks out, we're going to create an access token, which uniquely identifies the user's session. Still in the server, we do two things with the access token:

1. Store it in the database associated with that user
2. Attach it to a response cookie to be returned to the client. Be sure to set an expiration date/time to limit the user's session

Henceforth, the cookies will be attached to every request (and response) made between the client and server.

Step 6: Client > Making page requests

Back on the client side, we are now logged in. Every time the client makes a request for a page that requires authorization (i.e. they need to be logged in), the server obtains the access token from the cookie and checks it against the one in the database associated with that user. If it checks out, access is granted.

This should get you started. Be sure to clear the cookies upon logout!

If you want to use FXML, you should separate the controller (like you were doing with the SampleController). Then your fx:controller in your FXML should point to that.

Probably you are missing the initialize method in your controller, which is part of the Initializable interface. This method is called after the FXML is loaded, so I recommend you to set your image there.

Your SampleController class must be something like this:

public class SampleController implements Initializable {

    @FXML
    private ImageView imageView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        File file = new File("src/Box13.jpg");
        Image image = new Image(file.toURI().toString());
        imageView.setImage(image);
    }
}

I tested here and it's working.

Try this:

a = 1
b = 2
int_div  = a // b

The session is a server side thing, you cannot access it using jQuery. You can write an Http handler (that will share the sessionid if any) and return the value from there using $.ajax.

S.Lott's answer above almost works for me but ends up giving me partial lines. It turns out that it corrupts data on block boundaries because data holds the read blocks in reversed order. When ''.join(data) is called, the blocks are in the wrong order. This fixes that.

def tail(f, window=20):
    """
    Returns the last `window` lines of file `f` as a list.
    f - a byte file-like object
    """
    if window == 0:
        return []
    BUFSIZ = 1024
    f.seek(0, 2)
    bytes = f.tell()
    size = window + 1
    block = -1
    data = []
    while size > 0 and bytes > 0:
        if bytes - BUFSIZ > 0:
            # Seek back one whole BUFSIZ
            f.seek(block * BUFSIZ, 2)
            # read BUFFER
            data.insert(0, f.read(BUFSIZ))
        else:
            # file too small, start from begining
            f.seek(0,0)
            # only read what was not read
            data.insert(0, f.read(bytes))
        linesFound = data[0].count('\n')
        size -= linesFound
        bytes -= BUFSIZ
        block -= 1
    return ''.join(data).splitlines()[-window:]

1. A zone transfer is the only way to be sure you have all the subdomain records. If the DNS is correctly configured you should not normally be able to perform an external zone transfer.

2. The scans.io project has a database of DNS records that can be downloaded and searched for subdomains. This requires downloading the 87GB of DNS data, alternatively you can try the online search of the data at https://hackertarget.com/find-dns-host-records/

For Android Studio add the following to your top-level build.gradle file within the allprojects block

tasks.withType(JavaCompile) {
    options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 
}

Double precision means the numbers takes twice the word-length to store. On a 32-bit processor, the words are all 32 bits, so doubles are 64 bits. What this means in terms of performance is that operations on double precision numbers take a little longer to execute. So you get a better range, but there is a small hit on performance. This hit is mitigated a little by hardware floating point units, but its still there.

The N64 used a MIPS R4300i-based NEC VR4300 which is a 64 bit processor, but the processor communicates with the rest of the system over a 32-bit wide bus. So, most developers used 32 bit numbers because they are faster, and most games at the time did not need the additional precision (so they used floats not doubles).

All three systems can do single and double precision floating operations, but they might not because of performance. (although pretty much everything after the n64 used a 32 bit bus so...)

I guess its enough to return absolute path..

                        return view;
                    }
                }
    I used Frame Layout easy to use.
    Don't Forget to Add Background color or else fragment will overlap.
This is for First Fragment.
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:background="@color/colorPrimary"
        tools:context="com.example.sumedh.fragmentpractice1.MainActivity">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/editText" />
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:id="@+id/BtnNext"/>
    </FrameLayout>


Xml for Next Fragment.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
   android:background="@color/colorAccent"
    android:layout_height="match_parent">
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

</LinearLayout>

You can try the following: (This may be duplicate of the answers posted but I have added description)

Display all users that can be seen by the current user:

SELECT * FROM all_users;

Display all users in the Database:

SELECT * FROM dba_users;

Display the information of the current user:

SELECT * FROM user_users;

Lastly, this will display all users that can be seen by current users based on creation date:

SELECT * FROM all_users
ORDER BY created;

FWIW, in Boostrap 4.4, you can add .text-wrap style to things like buttons:

   <a href="#" class="btn btn-primary text-wrap">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>

https://getbootstrap.com/docs/4.4/utilities/text/#text-wrapping-and-overflow

i want to replace last ',' with space

if (fieldName.endsWith(",")) {
    fieldName = fieldName.substring(0, fieldName.length() - 1) + " ";
}

If you want to remove the trailing comma, simply get rid of the + " ".

You can run composer show -i (short for --installed).

In the latest version just use composer show.

The -i options has been deprecated.

You can also use the global instalation of composer: composer global show

#overlay {
    position: fixed;
    width: 100%;
    height: 100%;
    background: black url(spinner.gif) center center no-repeat;
    opacity: .5;
}

it's better to use rgba color instead of opacity to prevent applying alpha to spinner image.

background: rgba(0,0,0,.5) url(spinner.gif) center center no-repeat;

This should work:

start "" "c:\program files\php\php.exe" D:\mydocs\mp\index.php param1 param2

The start command interprets the first argument as a window title if it contains spaces. In this case, that means start considers your whole argument a title and sees no command. Passing "" (an empty title) as the first argument to start fixes the problem.

public static boolean doCollectionsContainSameElements(
        Collection<Integer> c1, Collection<Integer> c2){

    if (c1 == null || c2 == null) {
        return false;
    }
    else if (c1.size() != c2.size()) {
        return false;
    } else {    
        return c1.containsAll(c2) && c2.containsAll(c1);
    }       
}

Make a batch file "Pc.bat" as, typeperf -sc 1 "\mukit\processor(_Total)\%% Processor Time"

You can use the class MProcess,

/*
 *Md. Mukit Hasan
 *CSE-JU,35
 **/
import java.io.*;

public class MProcessor {
public MProcessor() {
String s;
try {
Process ps = Runtime.getRuntime().exec("Pc.bat");
BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
while((s = br.readLine()) != null) {
System.out.println(s);
}
}
catch( Exception ex ) {
System.out.println(ex.toString());
}
}

}

Then after some string manipulation, you get the CPU use. You can use the same process for other tasks.

Slight modification to the accepted answer.

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    if hasattr(sys, '_MEIPASS'):
        return os.path.join(sys._MEIPASS, relative_path)

    return os.path.join(os.path.abspath("."), relative_path)

The C language does not support pass by reference of any type. The closest equivalent is to pass a pointer to the type.

Here is a contrived example in both languages

C++ style API

void UpdateValue(int& i) {
  i = 42;
}

Closest C equivalent

void UpdateValue(int *i) {
  *i = 42;
}

Try the file command with -i option.

-i option Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say text/plain; charset=us-ascii rather than ASCII text.

  public Optional<String> InputStreamToBase64(Optional<InputStream> inputStream) throws IOException{
    if (inputStream.isPresent()) {
        ByteArrayOutputStream outpString base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));ut = new ByteArrayOutputStream();
        FileCopyUtils.copy(inputStream.get(), output);
        //TODO retrieve content type from file, & replace png below with it
        return Optional.ofNullable("data:image/png;base64," + DatatypeConverter.printBase64Binary(output.toByteArray()));
    }

    return Optional.empty();

Move your map variable into a scope where the event listener can use it. You are creating the map inside your initialize() function and nothing else can use it when created that way.

var map; //<-- This is now available to both event listeners and the initialize() function
function initialize() {
  var mapOptions = {
   center: new google.maps.LatLng(40.5472,12.282715),
   zoom: 6,
   mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("map-canvas"),
            mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", function() {
 var center = map.getCenter();
 google.maps.event.trigger(map, "resize");
 map.setCenter(center); 
});

No, Tab is just whitespace as far as HTML is concerned. I'd recommend an em-space instead which is this big (?| |?) ...typically 4 spaces wide — and is input as  .

You might even be able to get away with using the Unicode character (" ") for it, if you're lucky.

• Here is a list of Space characters and “zero-width spaces” in Unicode.

With the use of concat:

In [128]: df
Out[128]: 
   col_1  col_2
0      0      4
1      1      5
2      2      6
3      3      7

In [129]: pd.concat([df, pd.DataFrame(columns = [ 'column_new_1', 'column_new_2','column_new_3'])])
Out[129]: 
   col_1  col_2 column_new_1 column_new_2 column_new_3

3    3.0    7.0          NaN          NaN          NaN

Not very sure of what you wanted to do with [np.nan, 'dogs',3]. Maybe now set them as default values?

In [142]: df1 = pd.concat([df, pd.DataFrame(columns = [ 'column_new_1', 'column_new_2','column_new_3'])])
In [143]: df1[[ 'column_new_1', 'column_new_2','column_new_3']] = [np.nan, 'dogs', 3]

In [144]: df1
Out[144]: 
   col_1  col_2  column_new_1 column_new_2  column_new_3
0    0.0    4.0           NaN         dogs             3

If you plan to use Sphinx to document your code, it is capable of producing nicely formatted HTML docs for your parameters with their 'signatures' feature. http://sphinx-doc.org/domains.html#signatures

You should use the string replace function, with a single regex. Assuming by special characters, you mean anything that's not letter, here is a solution:

const str = "abc's test#s";_x000D_
console.log(str.replace(/[^a-zA-Z ]/g, ""));

To replace anything that starts with "text" until the last character:

text.+(.*)$

Example

text             hsjh sdjh sd          jhsjhsdjhsdj hsd
                                                      ^
                                                      last character

text.+(\ 123)

Example

text fuhfh283nfnd03no3 d90d3nd 3d 123 udauhdah au dauh ej2e
^                                   ^
From here                     To here

$(".input1").on('keyup', function (e) {
    if (e.key === 'Enter' || e.keyCode === 13) {
        // Do something
    }
});

// e.key is the modern way of detecting keys
// e.keyCode is deprecated (left here for for legacy browsers support)
// keyup is not compatible with Jquery select(), Keydown is.

I personally need to ensure the page keeps state, so all the text boxes and other input fields retain their values. by doing meta refresh it's like a new post, IsPostBack is always false so all your controls are in the initialized state again. To retain state put this at the end of your Page_Load(). create a hidden button on the page with an event hooked up, something like butRefresh with event butRefresh_Click(...). This code sets a timer on the page to fire a postback just like a user clicked the refresh button themselves. all state and session is retained. Enjoy! (P.S. you may need to put the directive in the @Page header EnableEventValidation="false" if you receive an error on postback.

//tell the browser to post back again in 5 seconds while keeping state of all controls
ClientScript.RegisterClientScriptBlock(this.GetType(), "refresh", "<script>setTimeout(function(){ " + ClientScript.GetPostBackClientHyperlink(butRefresh, "refresh") + " },5000);</script>");

Another one line command I used is:

[ -e file ] && rm file

Just recreate the Path variable in users. Go to user variables, highlight path, then new, the type in value. Look on another computer with same version windows. Usually it is in windows 10: Path %USERPROFILE%\AppData\Local\Microsoft\WindowsApps;

I had the same problem, but changing the contract namespace didn't work for me. So I tried a .Net 2 style web reference instead of a .Net 3.5 service reference. That worked.

To use a Web reference in Visual Studio 2008, click on 'Add Service Reference', then click 'Advanced' when the dialog box appears. In that you will find an option that will let you use a Web reference instead of a Service reference.

Try this it works!

Note that Color.GetSaturation() and Color.GetBrightness() return HSL values, not HSV.
The following code demonstrates the difference.

Color original = Color.FromArgb(50, 120, 200);
// original = {Name=ff3278c8, ARGB=(255, 50, 120, 200)}

double hue;
double saturation;
double value;
ColorToHSV(original, out hue, out saturation, out value);
// hue        = 212.0
// saturation = 0.75
// value      = 0.78431372549019607

Color copy = ColorFromHSV(hue, saturation, value);
// copy = {Name=ff3278c8, ARGB=(255, 50, 120, 200)}

// Compare that to the HSL values that the .NET framework provides: 
original.GetHue();        // 212.0
original.GetSaturation(); // 0.6
original.GetBrightness(); // 0.490196079

The following C# code is what you want. It converts between RGB and HSV using the algorithms described on Wikipedia. The ranges are 0 - 360 for hue, and 0 - 1 for saturation or value.

public static void ColorToHSV(Color color, out double hue, out double saturation, out double value)
{
    int max = Math.Max(color.R, Math.Max(color.G, color.B));
    int min = Math.Min(color.R, Math.Min(color.G, color.B));

    hue = color.GetHue();
    saturation = (max == 0) ? 0 : 1d - (1d * min / max);
    value = max / 255d;
}

public static Color ColorFromHSV(double hue, double saturation, double value)
{
    int hi = Convert.ToInt32(Math.Floor(hue / 60)) % 6;
    double f = hue / 60 - Math.Floor(hue / 60);

    value = value * 255;
    int v = Convert.ToInt32(value);
    int p = Convert.ToInt32(value * (1 - saturation));
    int q = Convert.ToInt32(value * (1 - f * saturation));
    int t = Convert.ToInt32(value * (1 - (1 - f) * saturation));

    if (hi == 0)
        return Color.FromArgb(255, v, t, p);
    else if (hi == 1)
        return Color.FromArgb(255, q, v, p);
    else if (hi == 2)
        return Color.FromArgb(255, p, v, t);
    else if (hi == 3)
        return Color.FromArgb(255, p, q, v);
    else if (hi == 4)
        return Color.FromArgb(255, t, p, v);
    else
        return Color.FromArgb(255, v, p, q);
}

PySpark only

I came across this post when looking to do the same in PySpark. The easiest way is to just add the parameter ascending=False:

df.orderBy("col1", ascending=False).show(10)

Reference: http://spark.apache.org/docs/2.1.0/api/python/pyspark.sql.html#pyspark.sql.DataFrame.orderBy

Since position: absolute; and viewport width were no options in my special case, there is another quick solution to solve the problem. The only condition is, that overflow in x-direction is not necessary for your website.

You can define negative margins for your element:

#help_panel {
    margin-left: -9999px;
    margin-right: -9999px;
}

But since we get overflow doing this, we have to avoid overflow in x-direction globally e.g. for body:

body {
    overflow-x: hidden;
}

You can set padding to choose the size of your content.

Note that this solution does not bring 100% width for content, but it is helpful in cases where you need e.g. a background color which has full width with a content still depending on container.

The simplest way would be to add the pull-left class to your dropdown-submenu

<li class="dropdown-submenu pull-left">

If your query has any JOINs, Mysql Workbench will not allow you to alter the table, even if your results are all from a single table.

For example, the following query

SELECT u.* FROM users u JOIN passwords p ON u.id=p.user_id WHERE p.password IS NULL;

will not allow you to edit the results or add rows, even though the results are limited to one table. You must specifically do something like:

SELECT * FROM users WHERE id=1012;

and then you can edit the row and add rows to the table.

I've found version 0.7.1 Alpha of PuTTY Connection Manager to be the most stable (it was previously hidden on the forums). It's available from PuTTY Connection Manager – Website Down.

This is a common question -- especially in today's environment of virtual environments. Unfortunately, the answer is not as straight-forward as one might assume.

dd is the obvious first choice, but dd is essentially a copy and that forces you to write every block of data (thus, initializing the file contents)... And that initialization is what takes up so much I/O time. (Want to make it take even longer? Use /dev/random instead of /dev/zero! Then you'll use CPU as well as I/O time!) In the end though, dd is a poor choice (though essentially the default used by the VM "create" GUIs). E.g:

dd if=/dev/zero of=./gentoo_root.img bs=4k iflag=fullblock,count_bytes count=10G

truncate is another choice -- and is likely the fastest... But that is because it creates a "sparse file". Essentially, a sparse file is a section of disk that has a lot of the same data, and the underlying filesystem "cheats" by not really storing all of the data, but just "pretending" that it's all there. Thus, when you use truncate to create a 20 GB drive for your VM, the filesystem doesn't actually allocate 20 GB, but it cheats and says that there are 20 GB of zeros there, even though as little as one track on the disk may actually (really) be in use. E.g.:

 truncate -s 10G gentoo_root.img

fallocate is the final -- and best -- choice for use with VM disk allocation, because it essentially "reserves" (or "allocates" all of the space you're seeking, but it doesn't bother to write anything. So, when you use fallocate to create a 20 GB virtual drive space, you really do get a 20 GB file (not a "sparse file", and you won't have bothered to write anything to it -- which means virtually anything could be in there -- kind of like a brand new disk!) E.g.:

fallocate -l 10G gentoo_root.img

Try using a format like %d.%02d

int iAmount = 10050;
printf("The number with fake decimal point is %d.%02d", iAmount/100, iAmount%100);

Another approach is to type cast it to double before printing it using %f like this:

printf("The number with fake decimal point is %0.2f", (double)(iAmount)/100);

My 2 cents :)

If you want your own custom Error Logging you can easily write your own code. I'll give you a snippet from one of my projects.

public void SaveLogFile(object method, Exception exception)
{
    string location = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"\FolderName\";
    try
    {
        //Opens a new file stream which allows asynchronous reading and writing
        using (StreamWriter sw = new StreamWriter(new FileStream(location + @"log.txt", FileMode.Append, FileAccess.Write, FileShare.ReadWrite)))
        {
            //Writes the method name with the exception and writes the exception underneath
            sw.WriteLine(String.Format("{0} ({1}) - Method: {2}", DateTime.Now.ToShortDateString(), DateTime.Now.ToShortTimeString(), method.ToString()));
            sw.WriteLine(exception.ToString()); sw.WriteLine("");
        }
    }
    catch (IOException)
    {
        if (!File.Exists(location + @"log.txt"))
        {
            File.Create(location + @"log.txt");
        }
    }
}

Then to actually write to the error log just write (q being the caught exception)

SaveLogFile(MethodBase.GetCurrentMethod(), `q`);

Do any of the following:

1- Update the play-services-maps library to the latest version:

com.google.android.gms:play-services-maps:16.1.0

2- Or include the following declaration within the <application> element of AndroidManifest.xml.

<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />

In the schema you have in your question, child1 or child2 can appear in any order, any number of times. So this sounds like what you are looking for.

Edit: if you wanted only one of them to appear an unlimited number of times, the unbounded would have to go on the elements instead:

Edit: Fixed type in XML.

Edit: Capitalised O in maxOccurs

<xs:element name="foo">
   <xs:complexType>
     <xs:choice maxOccurs="unbounded">
       <xs:element name="child1" type="xs:int" maxOccurs="unbounded"/>
       <xs:element name="child2" type="xs:string" maxOccurs="unbounded"/>
     </xs:choice>
   </xs:complexType>
</xs:element>

FWIW, for those just needing to snip off an indeterminate number of records from the head of the file, more > works well. This is useful just to have a smaller file to work with in the early stages of developing something.

Try this,

public static Double[][] multiplicar(Double A[][],Double B[][]){
    Double[][] C= new Double[2][2];
    int i,j,k;
     for (i = 0; i < 2; i++) {
         for (j = 0; j < 2; j++) {
             C[i][j] = 0.00000;
         }
     }
    for(i=0;i<2;i++){
        for(j=0;j<2;j++){
            for (k=0;k<2;k++){
                  C[i][j]+=(A[i][k]*B[k][j]);

            }

        }
    }
    return C;
}

This is using Captain Cucumber's answer, but with 2 additions.

1) allowing the function to get non scientific notation numbers and just return them as is (so you can throw a lot of input that some of the numbers are 0.00003123 vs 3.123e-05 and still have function work.

2) added support for negative numbers. (in original function, a negative number would end up like 0.0000-108904 from -1.08904e-05)

def getExpandedScientificNotation(flt):
    was_neg = False
    if not ("e" in flt):
        return flt
    if flt.startswith('-'):
        flt = flt[1:]
        was_neg = True 
    str_vals = str(flt).split('e')
    coef = float(str_vals[0])
    exp = int(str_vals[1])
    return_val = ''
    if int(exp) > 0:
        return_val += str(coef).replace('.', '')
        return_val += ''.join(['0' for _ in range(0, abs(exp - len(str(coef).split('.')[1])))])
    elif int(exp) < 0:
        return_val += '0.'
        return_val += ''.join(['0' for _ in range(0, abs(exp) - 1)])
        return_val += str(coef).replace('.', '')
    if was_neg:
        return_val='-'+return_val
    return return_val

In RedBeanPHP 2.0 there is a mass-export function which turns an entire collection of beans into arrays. This works with the JSON encoder..

json_encode( R::exportAll( $beans ) );

I'd like to add my Python3 answer for completeness:

from io import BytesIO
from zipfile import ZipFile
import requests

def get_zip(file_url):
    url = requests.get(file_url)
    zipfile = ZipFile(BytesIO(url.content))
    zip_names = zipfile.namelist()
    if len(zip_names) == 1:
        file_name = zip_names.pop()
        extracted_file = zipfile.open(file_name)
        return extracted_file
    return [zipfile.open(file_name) for file_name in zip_names]

jsonweb seems to be the best solution for me. See http://www.jsonweb.info/en/latest/

from jsonweb.encode import to_object, dumper

You may use bash functions in commands/pipelines as you would otherwise use regular programs. The functions are also available to subshells and transitively, Command Substitution:

VAR=$(scan)

Is the straighforward way to achieve the result you want in most cases. I will outline special cases below.

Preserving trailing Newlines:

One of the (usually helpful) side effects of Command Substitution is that it will strip any number of trailing newlines. If one wishes to preserve trailing newlines, one can append a dummy character to output of the subshell, and subsequently strip it with parameter expansion.

function scan2 () {
    local nl=$'\x0a';  # that's just \n
    echo "output${nl}${nl}" # 2 in the string + 1 by echo
}

# append a character to the total output.
# and strip it with %% parameter expansion.
VAR=$(scan2; echo "x"); VAR="${VAR%%x}"

echo "${VAR}---"

prints (3 newlines kept):

output


---

Use an output parameter: avoiding the subshell (and preserving newlines)

If what the function tries to achieve is to "return" a string into a variable , with bash v4.3 and up, one can use what's called a nameref. Namerefs allows a function to take the name of one or more variables output parameters. You can assign things to a nameref variable, and it is as if you changed the variable it 'points to/references'.

function scan3() {
    local -n outvar=$1    # -n makes it a nameref.
    local nl=$'\x0a'
    outvar="output${nl}${nl}"  # two total. quotes preserve newlines
}

VAR="some prior value which will get overwritten"

# you pass the name of the variable. VAR will be modified.
scan3 VAR

# newlines are also preserved.
echo "${VAR}==="

prints:

output

===

This form has a few advantages. Namely, it allows your function to modify the environment of the caller without using global variables everywhere.

Note: using namerefs can improve the performance of your program greatly if your functions rely heavily on bash builtins, because it avoids the creation of a subshell that is thrown away just after. This generally makes more sense for small functions reused often, e.g. functions ending in echo "$returnstring"

This is relevant. https://stackoverflow.com/a/38997681/5556676

make (or NMAKE, or whatever flavour of make you are using) can be quite picky about the format of makefiles - check that you didn't actually edit the file in any way, e.g. changed line endings, spaces <-> tabs, etc.

A bit late, but I just stumbled across the same problem while trying to provide analytics for my web app that involved sending app version based on the package.json version.

Configuration is as follows: React + Redux, Webpack 3.5.6

The json-loader isn't doing much since Webpack 2+, so after some fiddling with it, I ended up removing it.

The solution that actually worked for me, was simply using fetch. While this will most probably enforce some code changes to adapt to the async approach, it worked perfectly, especially given the fact that fetch will offer json decoding on the fly.

So here it is:

  fetch('../../package.json')
  .then(resp => resp.json())
  .then((packageJson) => {
    console.log(packageJson.version);
  });

Do keep in mind, that since we're talking about package.json specifically here, the file will not usually come bundled in your production build (or even dev for that matter), so you will have to use the CopyWebpackPlugin to have access to it when using fetch.

I would like to add a solution, that have helpt me to solve this problem in entity framework:

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
                .Where(x =>  x.DateTimeStart.Year == currentDateTime.Year &&
                             x.DateTimeStart.Month== currentDateTime.Month &&
                             x.DateTimeStart.Day == currentDateTime.Day
    );

I hope that it helps.

You can use axe selectors for this.

There are two approaches:

1. Immediate Parent axe Selector (<)

#a:hover < #content + #b

This axe style rule will select #b, which is the immediate sibling of #content, which is the immediate parent of #a which has a :hover state.

div {
display: inline-block;
margin: 30px;
font-weight: bold;
}

#content {
width: 160px;
height: 160px;
background-color: rgb(255, 0, 0);
}

#a, #b {
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
}

#a {
color: rgb(255, 0, 0);
background-color: rgb(255, 255, 0);
cursor: pointer;
}

#b {
display: none;
color: rgb(255, 255, 255);
background-color: rgb(0, 0, 255);
}

#a:hover < #content + #b {
display: inline-block;
}

<div id="content">
<div id="a">Hover me</div>
</div>

<div id="b">Show me</div>

<script src="https://rouninmedia.github.io/axe/axe.js"></script>

2. Remote Element axe Selector (\)

#a:hover \ #b

This axe style rule will select #b, which is present in the same document as #a which has a :hover state.

div {
display: inline-block;
margin: 30px;
font-weight: bold;
}

#content {
width: 160px;
height: 160px;
background-color: rgb(255, 0, 0);
}

#a, #b {
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
}

#a {
color: rgb(255, 0, 0);
background-color: rgb(255, 255, 0);
cursor: pointer;
}

#b {
display: none;
color: rgb(255, 255, 255);
background-color: rgb(0, 0, 255);
}

#a:hover \ #b {
display: inline-block;
}

<div id="content">
<div id="a">Hover me</div>
</div>

<div id="b">Show me</div>

<script src="https://rouninmedia.github.io/axe/axe.js"></script>

class ImageStore: NSObject { 
    static let imageCache = NSCache<NSString, UIImage>()
}

extension UIImageView {
    func url(_ url: String?) {
        DispatchQueue.global().async { [weak self] in
            guard let stringURL = url, let url = URL(string: stringURL) else {
                return
            }
            func setImage(image:UIImage?) {
                DispatchQueue.main.async {
                    self?.image = image
                }
            }
            let urlToString = url.absoluteString as NSString
            if let cachedImage = ImageStore.imageCache.object(forKey: urlToString) {
                setImage(image: cachedImage)
            } else if let data = try? Data(contentsOf: url), let image = UIImage(data: data) {
                DispatchQueue.main.async {
                    ImageStore.imageCache.setObject(image, forKey: urlToString)
                    setImage(image: image)
                }
            }else {
                setImage(image: nil)
            }
        }
    }
}

Usage :

let imageView = UIImageView()
imageView.url("image url")

Martin Encountered the same issue with a Minecraft Mod project when I changed the Main folder location. Normally I would open the project like this

This is how my path looked when I started the project

I got the same "The project description file (.project) for my project is missing." Error.

I later found the .project file in the main folder like this.

This is the location where I found the .project file

I found that going eclipse to "File->Open Project from File System or Archive" and navigate to your main project folder with the .project file solved the problem.

My project is already included

This is my first post in here hoping it can help you out, Martin.

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

The UPDATE statement is given so that older fields can be updated to new value. If your older values are the same as your new ones, why would you need to update it in any case?

For eg. if your columns a to g are already set as 2 to 8; there would be no need to re-update it.

Alternatively, you can use:

INSERT INTO table (id,a,b,c,d,e,f,g)
VALUES (1,2,3,4,5,6,7,8) 
ON DUPLICATE KEY
    UPDATE a=a, b=b, c=c, d=d, e=e, f=f, g=g;

To get the id from LAST_INSERT_ID; you need to specify the backend app you're using for the same.

For LuaSQL, a conn:getlastautoid() fetches the value.

It's under "GCC 4.2 Preprocessing" (or just put "prepro" in the search box)...

...however, for the life of me I can't get it to work.

I have my standard Debug and Release configurations, and I want to define DEBUG=1 in the debugging configuration. But after adding it as a value:

(in the settings window) > Preprocessor Macros : DEBUG=1

#if DEBUG
    printf("DEBUG is set!");
#endif 

...never prints/gets called. It's driving me crazy...

Like "VB's On Error Resume Next?" That sounds kind of scary. First recommendation is don't do it. Second recommendation is don't do it and don't think about it. You need to isolate your faults better. As to how to approach this problem, it depends on how you're code is structured. If you are using a pattern like MVC or the like then this shouldn't be too difficult and would definitely not require a global exception swallower. Secondly, look for a good logging library like log4net or use tracing. We'd need to know more details like what kinds of exceptions you're talking about and what parts of your application may result in exceptions being thrown.

From the Developer Guide:

android:id="@+id/my_button"

The at-symbol (@) at the beginning of the string indicates that the XML parser should parse and expand the rest of the ID string and identify it as an ID resource. The plus-symbol (+) means that this is a new resource name that must be created and added to our resources (in the R.java file). There are a number of other ID resources that are offered by the Android framework. When referencing an Android resource ID, you do not need the plus-symbol, but must add the android package namespace, like so:

android:id="@android:id/empty"

Don't know about what the error you are facing exactly. But log4j:WARN No appenders could be found for logger error, is due to the log4j jar file that you have included in your project.

Initializing log4j is needed but actually Log4j is not necessary for your project. So Right click on your Project → Properties → Java Build Path → Libraries.. Search for log4j jar file and remove it.

Hope it will work fine now.

This will print the IP addresses in the output of ipconfig:

@echo off
set ip_address_string="IPv4 Address"
rem Uncomment the following line when using older versions of Windows without IPv6 support (by removing "rem")
rem set ip_address_string="IP Address"
echo Network Connection Test
for /f "usebackq tokens=2 delims=:" %%f in (`ipconfig ^| findstr /c:%ip_address_string%`) do echo Your IP Address is: %%f

To only print the first IP address, just add goto :eof (or another label to jump to instead of :eof) after the echo, or in a more readable form:

set ip_address_string="IPv4 Address"
rem Uncomment the following line when using older versions of Windows without IPv6 support (by removing "rem")
rem set ip_address_string="IP Address"
for /f "usebackq tokens=2 delims=:" %%f in (`ipconfig ^| findstr /c:%ip_address_string%`) do (
    echo Your IP Address is: %%f
    goto :eof
)

A more configurable way would be to actually parse the output of ipconfig /all a little bit, that way you can even specify the adapter whose IP address you want:

@echo off
setlocal enabledelayedexpansion
::just a sample adapter here:
set "adapter=Ethernet adapter VirtualBox Host-Only Network"
set adapterfound=false
echo Network Connection Test
for /f "usebackq tokens=1-2 delims=:" %%f in (`ipconfig /all`) do (
    set "item=%%f"
    if /i "!item!"=="!adapter!" (
        set adapterfound=true
    ) else if not "!item!"=="!item:IP Address=!" if "!adapterfound!"=="true" (
        echo Your IP Address is: %%g
        set adapterfound=false
    )
)

I encounter same error, and incognito mode also has same issue. I resolve this issue by clear Chrome history.

You can use strcpy to populate it. You can also initialize it from another struct.

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

struct name {
    char first[20];
    char last[20];
};

int main() {
    struct name sara;
    struct name other;

    strcpy(sara.first,"Sara");
    strcpy(sara.last, "Black");

    other = sara;

    printf("struct: %s\t%s\n", sara.first, sara.last);
    printf("other struct: %s\t%s\n", other.first, other.last);

}

None of the above solutions worked for me, however instead I wrapped my content in a div (#outer-wrap) and then used the following CSS:

body {
   overflow: hidden;
}
#outer-wrap {
    -webkit-overflow-scrolling: touch;
     height: 100vh;
     overflow: auto;
}

Obviously only works in browsers that support viewport widths/heights of course.

To set the directory selected path and the retrieve the new directory:

dlgBrowseForLogDirectory.SelectedPath = m_LogDirectory;
if (dlgBrowseForLogDirectory.ShowDialog() == DialogResult.OK)
{
     txtLogDirectory.Text = dlgBrowseForLogDirectory.SelectedPath;
}

I found using CSS inside my html inside my php did the trick for me.

<?php             
    echo '<h2 media="screen and (max-width: 480px)">'; 
    echo 'My headline';
    echo '</h2>'; 

    echo '<h1 media="screen and (min-width: 481px)">'; 
    echo 'My headline';
    echo '</h1>'; 

    ?>

This will output a smaller sized headline if the screen is 480px or less. So no need to pass any vars using JS or similar.

JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object or new Array), is as follows:

var obj = {
    'key': 'value',
    'another key': 'another value',
     anUnquotedKey: 'more value!'
};

For arrays it's:

var arr = [
    'value',
    'another value',
    'even more values'
];

If you need objects within objects, that's fine too:

var obj = {
    'subObject': {
        'key': 'value'
    },
    'another object': {
         'some key': 'some value',
         'another key': 'another value',
         'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
    }
}

This convenient method of being able to instantiate static data is what led to the JSON data format.

JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:

{"foo":"bar", "keyWithIntegerValue":123}

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

If you have multiple, dynamic height items, use the CSS display values of table and table-cell:

HTML

<html>
<body>

  <div class="valign bottom">
    <div>

      <div>my bottom aligned div 1</div>
      <div>my bottom aligned div 2</div>
      <div>my bottom aligned div 3</div>

    </div>
  </div>

</body>
</html>

CSS

html,
body {
  width: 100%;
  height: 100%;
}
.valign {
  display: table;
  width: 100%;
  height: 100%;
}
.valign > div {
  display: table-cell;
  width: 100%;
  height: 100%;
}
.valign.bottom > div {
  vertical-align: bottom;
}

I've created a JSBin demo here: http://jsbin.com/INOnAkuF/2/edit

The demo also has an example how to vertically center align using the same technique.

You must have inadvertently upgraded your system pip (probably through something like sudo pip install pip --upgrade)

pip 10.x adjusts where its internals are situated. The pip3 command you're seeing is one provided by your package maintainer (presumably debian based here?) and is not a file managed by pip.

You can read more about this on pip's issue tracker

You'll probably want to not upgrade your system pip and instead use a virtualenv.

To recover the pip3 binary you'll need to sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.

If you want to continue in "unsupported territory" (upgrading a system package outside of the system package manager), you can probably get away with python3 -m pip ... instead of pip3.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

The first thing you need is the real File path If you have it great, if you are using URI then use this method to get the real Path:

 public static String getRealPathFromURI(Uri contentURI,Context context) {
    String path= contentURI.getPath();
    try {
        Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();

        cursor = context.getContentResolver().query(
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        cursor.close();
    }
    catch(Exception e)
    {
        return path;
    }
    return path;
}

extract your Bitmap for example:

  try {
                            Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);

                        }
                        catch (IOException e)
                        {
                            Log.e("IOException",e.toString());
                        }

you can use decodeFile() instead if you wish.

Now that you have the Bitmap and the real Path get the Orientation of the Image:

 private static int getExifOrientation(String src) throws IOException {
        int orientation = 1;

        ExifInterface exif = new ExifInterface(src);
        String orientationString=exif.getAttribute(ExifInterface.TAG_ORIENTATION);
        try {
            orientation = Integer.parseInt(orientationString);
        }
        catch(NumberFormatException e){}

        return orientation;
    }

and finally rotate it to the right position like so:

public static Bitmap rotateBitmap(String src, Bitmap bitmap) {
        try {
            int orientation = getExifOrientation(src);

            if (orientation == 1) {
                return bitmap;
            }

            Matrix matrix = new Matrix();
            switch (orientation) {
                case 2:
                    matrix.setScale(-1, 1);
                    break;
                case 3:
                    matrix.setRotate(180);
                    break;
                case 4:
                    matrix.setRotate(180);
                    matrix.postScale(-1, 1);
                    break;
                case 5:
                    matrix.setRotate(90);
                    matrix.postScale(-1, 1);
                    break;
                case 6:
                    matrix.setRotate(90);
                    break;
                case 7:
                    matrix.setRotate(-90);
                    matrix.postScale(-1, 1);
                    break;
                case 8:
                    matrix.setRotate(-90);
                    break;
                default:
                    return bitmap;
            }

            try {
                Bitmap oriented = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
                bitmap.recycle();
                return oriented;
            } catch (OutOfMemoryError e) {
                e.printStackTrace();
                return bitmap;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        return bitmap;
    }

That's it , you now have the bitmap rotated to the right position.

cheers.

A very general command prompt how to for java is

javac mainjava.java
java mainjava

You'll very often see people doing

javac *.java
java mainjava

As for the subclass problem that's probably occurring because a path is missing from your class path, the -c flag I believe is used to set that.

I think this problem can be solved in this way:

 <TextView
        android:id="@+id/leftText"
        android:includeFontPadding="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="30dp"
        android:text="Hello World!\nhello world" />

 <TextView
        android:id="@+id/rightUpperText"
        android:includeFontPadding="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/leftText"
        android:layout_alignTop="@+id/leftText"
        android:textSize="30dp"
        android:text="Hello World!" />

 <TextView
        android:id="@+id/rightLowerText"
        android:includeFontPadding="false"

Though the line of special characters in rightLowerText looks a little bit higher than the second line of leftText, their baselines are stilled aligned.

Check if you have all NLTK libraries.

Or is it like saying "Since this is python v2.7, use that different 'print' function that has also been added to python v2.7, after it was added in python 3. So my 'print' will no longer be statements (eg print "message" ) but functions (eg, print("message", options). That way when my code is run in python 3, 'print' will not break."

In

from __future__ import print_function

print_function is the module containing the new implementation of 'print' as per how it is behaving in python v3.

This has more explanation: http://python3porting.com/noconv.html

You have to use square bracket notation when -

1. The property name is number.

   var ob = {
     1: 'One',
     7 : 'Seven'
   }
   ob.7  // SyntaxError
   ob[7] // "Seven"
   

2. The property name has special character.

   var ob = {
     'This is one': 1,
     'This is seven': 7,
   }  
   ob.'This is one'  // SyntaxError
   ob['This is one'] // 1
   

3. The property name is assigned to a variable and you want to access the property value by this variable.

   var ob = {
     'One': 1,
     'Seven': 7,
   }
   
   var _Seven = 'Seven';
   ob._Seven  // undefined
   ob[_Seven] // 7
   

A move from WebForms to MVC requires a complete sea-change in logic and brain processes. You're no longer interacting with the 'form' both server-side and client-side (and in fact even with WebForms you weren't interacting client-side). You've probably just mixed up a bit of thinking there, in that with WebForms and RUNAT="SERVER" you were merely interacting with the building of the Web page.

MVC is somewhat similar in that you have server-side code in constructing the model (the data you need to build what your user will see), but once you have built the HTML you need to appreciate that the link between the server and the user no longer exists. They have a page of HTML, that's it.

So the HTML you are building is read-only. You pass the model through to the Razor page, which will build HTML appropriate to that model.

If you want to have a hidden element which sets true or false depending on whether this is the first view or not you need a bool in your model, and set it to True in the Action if it's in response to a follow up. This could be done by having different actions depending on whether the request is [HttpGet] or [HttpPost] (if that's appropriate for how you set up your form: a GET request for the first visit and a POST request if submitting a form).

Alternatively the model could be set to True when it's created (which will be the first time you visit the page), but after you check the value as being True or False (since a bool defaults to False when it's instantiated). Then using:

@Html.HiddenFor(x => x.HiddenPostBack)

in your form, which will put a hidden True. When the form is posted back to your server the model will now have that value set to True.

It's hard to give much more advice than that as your question isn't specific as to why you want to do this. It's perhaps vital that you read a good book on moving to MVC from WebForms, such as Steve Sanderson's Pro ASP.NET MVC.

To prevent quirks mode, define a 'doctype' like :

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

To make IE render the page in IE9 document mode :

<meta http-equiv="x-ua-compatible" content="IE=9">

Please note that "IE=edge" will make IE render the page with the most recent document mode, rather than IE9 document mode.

The Ternary operator is just written as a boolean expression followed by a questionmark and then two further expressions separated by a colon.

The first thing that I can see that you have got wrong is that your first expression isn't returning a boolean or anything sensible that could be converted to a boolean. Your first expression is always going to return a jQuery object that has no sensible interpretation as a boolean and what it does convert to is probably an unchanging interpretation. You are always best off returning something that has a well known boolean interpretation, if nothign else for the sake of readability.

The second thing is that you are putting a semicolon after each of your expressions which is wrong. In effect this is saying "end of construct" and so is breaking your ternary operator.

In this situation though you probably can do this a more easy way. If you use classes and the toggleClass method then you can easily get it to switch a class on and off and then you can put your styles in that class definition (Kudos to @yoavmatchulsky for suggesting use of classes up there in comments).

A fiddle of this is found here: http://jsfiddle.net/chrisvenus/wSMnV/ (based on the original)

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?

Depending on your language, there may be a to_json method available. That will escape many things that break CSVs.

You can have multiple .gitignore, each one of course in its own directory.
To check which gitignore rule is responsible for ignoring a file, use git check-ignore: git check-ignore -v -- afile.

And you can have different version of a .gitignore file per branch: I have already seen that kind of configuration for ensuring one branch ignores a file while the other branch does not: see this question for instance.

If your repo includes several independent projects, it would be best to reference them as submodules though.
That would be the actual best practices, allowing each of those projects to be cloned independently (with their respective .gitignore files), while being referenced by a specific revision in a global parent project.
See true nature of submodules for more.

Note that, since git 1.8.2 (March 2013) you can do a git check-ignore -v -- yourfile in order to see which gitignore run (from which .gitignore file) is applied to 'yourfile', and better understand why said file is ignored.
See "which gitignore rule is ignoring my file?"

I changed a bit and it worked like this, dumped into one single array, provided all the images are of same dimensions.

png = []
for image_path in glob.glob("./train/*.png"):
    png.append(misc.imread(image_path))    

im = np.asarray(png)

print 'Importing done...', im.shape

If global tab/spaces indentation settings no longer fit your needs (I.E. you find yourself working with legacy codebases with varied indentation formats, and you need to quickly switch between them, and the auto-detect isn't working) you might try the tab-control plugin, which sort of duplicates the functionality of the menu in your screenshot.

Try changing the User that owns the service to Local System or use your admin account.

Under services, I changed the Service SQL Server (MSSQLSERVER) Log On from NT Service\Sql... To Local System. Right click the service and go to the Log On Tab and select the radio button Local System Account. You could also force another User to run it too if that fits better.

In light of those TOS alterations last year we built an API that gives access to Google's search. It was for our own use only but after some requests we decided to open it up. We're planning to add additional search engines in the future!

Should anyone be looking for an easy way to implement / acquire search results you are free to sign up and give the REST API a try: https://searchapi.io

It returns JSON results and should be easy enough to implement with the detailed docs.

It's a shame that Bing and Yahoo are miles ahead on Google in this regard. Their APIs aren't cheap, but at least available.

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

There are three ways of defining things in Scala:

• def defines a method
• val defines a fixed value (which cannot be modified)
• var defines a variable (which can be modified)

Looking at your code:

def person = new Person("Kumar",12)

This defines a new method called person. You can call this method only without () because it is defined as parameterless method. For empty-paren method, you can call it with or without '()'. If you simply write:

person

then you are calling this method (and if you don't assign the return value, it will just be discarded). In this line of code:

person.age = 20

what happens is that you first call the person method, and on the return value (an instance of class Person) you are changing the age member variable.

And the last line:

println(person.age)

Here you are again calling the person method, which returns a new instance of class Person (with age set to 12). It's the same as this:

println(person().age)

set.seed(1)
example <- data.frame(col1 = rnorm(10, 0, 1), col2 = rnorm(10, 2, 3))
namevector <- c("col3", "col4")
example[ , namevector] <- NA

example
#          col1       col2 col3 col4
# 1  -0.6264538  6.5353435   NA   NA
# 2   0.1836433  3.1695297   NA   NA
# 3  -0.8356286  0.1362783   NA   NA
# 4   1.5952808 -4.6440997   NA   NA
# 5   0.3295078  5.3747928   NA   NA
# 6  -0.8204684  1.8651992   NA   NA
# 7   0.4874291  1.9514292   NA   NA

# 10 -0.3053884  3.7817040   NA   NA

For people that have PowerShell 3 or later (i.e. Windows Server 2012+ or Windows Server 2008 R2 with the Windows Management Framework 4.0 update), you can do this one-liner instead of invoking System.Net.WebRequest:

$statusCode = wget http://stackoverflow.com/questions/20259251/ | % {$_.StatusCode}

This error happened to me, generally it'll be a problem due to not including the mysql-connector.jar in your eclipse project (or your IDE).

In my case, it was because of a problem on the OS.

I was editing a table in phpmyadmin, and mysql hung, I restarted Ubuntu. I cleaned the project without being successful. This morning, when I've tried the web server, it work perfectly the first time.

At the first reboot, the OS recognized that there was a problem, and after the second one, it was fixed. I hope this will save some time to somebody that "could" have this problem!

I had the same warning using the raster package.

> my_mask[my_mask[] != 1] <- NA
Error: cannot allocate vector of size 5.4 Gb

The solution is really simple and consist in increasing the storage capacity of R, here the code line:

##To know the current storage capacity
> memory.limit()
[1] 8103
## To increase the storage capacity
> memory.limit(size=56000)
[1] 56000    
## I did this to increase my storage capacity to 7GB

Hopefully, this will help you to solve the problem Cheers

As pointed in Vlad's answer, you are running out of free color slots. One way to get around that would be to cache the colors: whenever you try a RGB combination, the routine should first check if the combination is in the cache; if it is in the cache, then it should use that one instead of creating a new one from scratch; new colors would then only be created if they're not yet in cache.

Here's the implementation I use; it uses XSSF plus Guava's LoadingCache and is geared towards generationg XSSF colors from CSS rgb(r, g, b) declarations, but it should be relatively trivial to adapt it to HSSF:

    private final LoadingCache<String, XSSFColor> colorsFromCSS = CacheBuilder.newBuilder()
            .build(new CacheLoader<String, XSSFColor>() {

                private final Pattern RGB = Pattern.compile("rgb\\(\\s*(\\d+)\\s*, \\s*(\\d+)\\s*,\\s*(\\d+)\\s*\\)");

                @Override
                public XSSFColor load(String style) throws Exception {
                    Matcher mat = RGB.matcher(style);
                    if (!mat.find()) {
                        throw new IllegalStateException("Couldn't read CSS color: " + style);
                    }                       
                    return new XSSFColor(new java.awt.Color(
                            Integer.parseInt(mat.group(1)), 
                            Integer.parseInt(mat.group(2)), 
                            Integer.parseInt(mat.group(3))));
                }

            });

Perhaps someone else could post a HSSF equivalent? ;)

var num = 34.7654;

num = Math.round(num * 10) / 10;

console.log(num); // Logs: 34.8

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.

This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.

select num_rows from all_tables where table_name = 'MY_TABLE'

This query counts the current number of rows in MY_TABLE

select count(*) from my_table

By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.

1. In the documentation there's an asterisk by the column name, which leads to this note:

   Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.

   This means that unless you have gathered statistics on the table then this column will not have any data.

2. Statistics gathered in 11g+ with the default estimate_percent, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.

If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.

Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.

There are at least 5 ways to do this:

If you want to convert to integers only, another fast (and short) way is the double-bitwise not (i.e. using two tilde characters):

e.g.

~~x;

Reference: http://james.padolsey.com/cool-stuff/double-bitwise-not/

The 5 common ways I know so far to convert a string to a number all have their differences (there are more bitwise operators that work, but they all give the same result as ~~). This JSFiddle shows the different results you can expect in the debug console: http://jsfiddle.net/TrueBlueAussie/j7x0q0e3/22/

var values = ["123",
          undefined,
          "not a number",
          "123.45",
          "1234 error",
          "2147483648",
          "4999999999"
          ];

for (var i = 0; i < values.length; i++){
    var x = values[i];

    console.log(x);
    console.log(" Number(x) = " + Number(x));
    console.log(" parseInt(x, 10) = " + parseInt(x, 10));
    console.log(" parseFloat(x) = " + parseFloat(x));
    console.log(" +x = " + +x);
    console.log(" ~~x = " + ~~x);
}

Debug console:

123
  Number(x) = 123
  parseInt(x, 10) = 123
  parseFloat(x) = 123
  +x = 123
  ~~x = 123
undefined
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
null
  Number(x) = 0
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = 0
  ~~x = 0
"not a number"
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
123.45
  Number(x) = 123.45
  parseInt(x, 10) = 123
  parseFloat(x) = 123.45
  +x = 123.45
  ~~x = 123
1234 error
  Number(x) = NaN
  parseInt(x, 10) = 1234
  parseFloat(x) = 1234
  +x = NaN
  ~~x = 0
2147483648
  Number(x) = 2147483648
  parseInt(x, 10) = 2147483648
  parseFloat(x) = 2147483648
  +x = 2147483648
  ~~x = -2147483648
4999999999
  Number(x) = 4999999999
  parseInt(x, 10) = 4999999999
  parseFloat(x) = 4999999999
  +x = 4999999999
  ~~x = 705032703

The ~~x version results in a number in "more" cases, where others often result in undefined, but it fails for invalid input (e.g. it will return 0 if the string contains non-number characters after a valid number).

Overflow

Please note: Integer overflow and/or bit truncation can occur with ~~, but not the other conversions. While it is unusual to be entering such large values, you need to be aware of this. Example updated to include much larger values.

Some Perf tests indicate that the standard parseInt and parseFloat functions are actually the fastest options, presumably highly optimised by browsers, but it all depends on your requirement as all options are fast enough: http://jsperf.com/best-of-string-to-number-conversion/37

This all depends on how the perf tests are configured as some show parseInt/parseFloat to be much slower.

My theory is:

• Lies
• Darn lines
• Statistics
• JSPerf results :)

In WebStorm, you can right click ? Refactor ? Rename on the name of the component in the TypeScript file and it will change the name everywhere.

Pretty simple by using previousNavigation object:

this.router.events
  .pipe(
    filter(e => e instanceof NavigationEnd && this.router.getCurrentNavigation().previousNavigation),
    map(() => this.router.getCurrentNavigation().previousNavigation.finalUrl.toString()),
  )
  .subscribe(previousUrl => {}); 

You can really simplify this whole program by using time.sleep:

import time
run = raw_input("Start? > ")
mins = 0
# Only run if the user types in "start"
if run == "start":
    # Loop until we reach 20 minutes running
    while mins != 20:
        print(">>>>>>>>>>>>>>>>>>>>> {}".format(mins))
        # Sleep for a minute
        time.sleep(60)
        # Increment the minute total
        mins += 1
    # Bring up the dialog box here

For your Q2, there are already answers to your question. For your Q1, and more generally when you know that the key's filtering should give a unique value, there's no need to use Streams at all.

Just use get or getOrDefault, i.e:

List<String> list1 = id1.getOrDefault(1, Collections.emptyList());

SELECT [UserID] FROM [User] u LEFT JOIN (
SELECT [TailUser], [Weight] FROM [Edge] WHERE [HeadUser] = 5043) t on t.TailUser=u.USerID

The inner vertical alignment will depend on font height and input height, so, it can be adjusted using padding !!!

Try some like :

.InVertAlign {
   height: 40px;
   line-height: 40px;
   font-size: 2em;
   padding: 0px 14px 3px 5px;
}

...

<input type="text" class="InVertAlign" />

Remember to adjust the values on css class according to your needs !

For more general boolean functions that you would like to use as a filter and that depend on more than one column, you can use:

df = df[df[['col_1','col_2']].apply(lambda x: f(*x), axis=1)]

where f is a function that is applied to every pair of elements (x1, x2) from col_1 and col_2 and returns True or False depending on any condition you want on (x1, x2).

-f is the correct flag, but for the test operator, not rm

[ -f "$THEFILE" ] && rm "$THEFILE"

this ensures that the file exists and is a regular file (not a directory, device node etc...)

I've used DBDesigner before. It is an open source tool. You might check that out. Not sure if it fits your needs.

Best of luck!

tl;dr

Instant and LocalDateTime are two entirely different animals: One represents a moment, the other does not.

• Instant represents a moment, a specific point in the timeline.
• LocalDateTime represents a date and a time-of-day. But lacking a time zone or offset-from-UTC, this class cannot represent a moment. It represents potential moments along a range of about 26 to 27 hours, the range of all time zones around the globe. A LocalDateTime value is inherently ambiguous.

Incorrect Presumption

LocalDateTime is rather date/clock representation including time-zones for humans.

Your statement is incorrect: A LocalDateTime has no time zone. Having no time zone is the entire point of that class.

To quote that class’ doc:

This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

So Local… means “not zoned, no offset”.

Instant

An Instant is a moment on the timeline in UTC, a count of nanoseconds since the epoch of the first moment of 1970 UTC (basically, see class doc for nitty-gritty details). Since most of your business logic, data storage, and data exchange should be in UTC, this is a handy class to be used often.

Instant instant = Instant.now() ;  // Capture the current moment in UTC.

OffsetDateTime

The class OffsetDateTime class represents a moment as a date and time with a context of some number of hours-minutes-seconds ahead of, or behind, UTC. The amount of offset, the number of hours-minutes-seconds, is represented by the ZoneOffset class.

If the number of hours-minutes-seconds is zero, an OffsetDateTime represents a moment in UTC the same as an Instant.

ZoneOffset

The ZoneOffset class represents an offset-from-UTC, a number of hours-minutes-seconds ahead of UTC or behind UTC.

A ZoneOffset is merely a number of hours-minutes-seconds, nothing more. A zone is much more, having a name and a history of changes to offset. So using a zone is always preferable to using a mere offset.

ZoneId

A time zone is represented by the ZoneId class.

A new day dawns earlier in Paris than in Montréal, for example. So we need to move the clock’s hands to better reflect noon (when the Sun is directly overhead) for a given region. The further away eastward/westward from the UTC line in west Europe/Africa the larger the offset.

A time zone is a set of rules for handling adjustments and anomalies as practiced by a local community or region. The most common anomaly is the all-too-popular lunacy known as Daylight Saving Time (DST).

A time zone has the history of past rules, present rules, and rules confirmed for the near future.

These rules change more often than you might expect. Be sure to keep your date-time library's rules, usually a copy of the 'tz' database, up to date. Keeping up-to-date is easier than ever now in Java 8 with Oracle releasing a Timezone Updater Tool.

Specify a proper time zone name in the format of Continent/Region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 2-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

Time Zone = Offset + Rules of Adjustments

ZoneId z = ZoneId.of( “Africa/Tunis” ) ; 

ZonedDateTime

Think of ZonedDateTime conceptually as an Instant with an assigned ZoneId.

ZonedDateTime = ( Instant + ZoneId )

To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone):

ZonedDateTime zdt = ZonedDateTime.now( z ) ;  // Pass a `ZoneId` object such as `ZoneId.of( "Europe/Paris" )`. 

Nearly all of your backend, database, business logic, data persistence, data exchange should all be in UTC. But for presentation to users you need to adjust into a time zone expected by the user. This is the purpose of the ZonedDateTime class and the formatter classes used to generate String representations of those date-time values.

ZonedDateTime zdt = instant.atZone( z ) ;
String output = zdt.toString() ;                 // Standard ISO 8601 format.

You can generate text in localized format using DateTimeFormatter.

DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( Locale.CANADA_FRENCH ) ; 
String outputFormatted = zdt.format( f ) ;

LocalDate, LocalTime, LocalDateTime

The "local" date time classes, LocalDateTime, LocalDate, LocalTime, are a different kind of critter. The are not tied to any one locality or time zone. They are not tied to the timeline. They have no real meaning until you apply them to a locality to find a point on the timeline.

The word “Local” in these class names may be counter-intuitive to the uninitiated. The word means any locality, or every locality, but not a particular locality.

So for business apps, the "Local" types are not often used as they represent just the general idea of a possible date or time not a specific moment on the timeline. Business apps tend to care about the exact moment an invoice arrived, a product shipped for transport, an employee was hired, or the taxi left the garage. So business app developers use Instant and ZonedDateTime classes most commonly.

So when would we use LocalDateTime? In three situations:

• We want to apply a certain date and time-of-day across multiple locations.
• We are booking appointments.
• We have an intended yet undetermined time zone.

Notice that none of these three cases involve a single certain specific point on the timeline, none of these are a moment.

One time-of-day, multiple moments

Sometimes we want to represent a certain time-of-day on a certain date, but want to apply that into multiple localities across time zones.

For example, "Christmas starts at midnight on the 25th of December 2015" is a LocalDateTime. Midnight strikes at different moments in Paris than in Montréal, and different again in Seattle and in Auckland.

LocalDate ld = LocalDate.of( 2018 , Month.DECEMBER , 25 ) ;
LocalTime lt = LocalTime.MIN ;   // 00:00:00
LocalDateTime ldt = LocalDateTime.of( ld , lt ) ;  // Christmas morning anywhere. 

Another example, "Acme Company has a policy that lunchtime starts at 12:30 PM at each of its factories worldwide" is a LocalTime. To have real meaning you need to apply it to the timeline to figure the moment of 12:30 at the Stuttgart factory or 12:30 at the Rabat factory or 12:30 at the Sydney factory.

Booking appointments

Another situation to use LocalDateTime is for booking future events (ex: Dentist appointments). These appointments may be far enough out in the future that you risk politicians redefining the time zone. Politicians often give little forewarning, or even no warning at all. If you mean "3 PM next January 23rd" regardless of how the politicians may play with the clock, then you cannot record a moment – that would see 3 PM turn into 2 PM or 4 PM if that region adopted or dropped Daylight Saving Time, for example.

For appointments, store a LocalDateTime and a ZoneId, kept separately. Later, when generating a schedule, on-the-fly determine a moment by calling LocalDateTime::atZone( ZoneId ) to generate a ZonedDateTime object.

ZonedDateTime zdt = ldt.atZone( z ) ;  // Given a date, a time-of-day, and a time zone, determine a moment, a point on the timeline.

If needed, you can adjust to UTC. Extract an Instant from the ZonedDateTime.

Instant instant = zdt.toInstant() ;  // Adjust from some zone to UTC. Same moment, same point on the timeline, different wall-clock time.

Unknown zone

Some people might use LocalDateTime in a situation where the time zone or offset is unknown.

I consider this case inappropriate and unwise. If a zone or offset is intended but undetermined, you have bad data. That would be like storing a price of a product without knowing the intended currency (dollars, pounds, euros, etc.). Not a good idea.

All date-time types

For completeness, here is a table of all the possible date-time types, both modern and legacy in Java, as well as those defined by the SQL standard. This might help to place the Instant & LocalDateTime classes in a larger context.

Notice the odd choices made by the Java team in designing JDBC 4.2. They chose to support all the java.time times… except for the two most commonly used classes: Instant & ZonedDateTime.

But not to worry. We can easily convert back and forth.

Converting Instant.

// Storing
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
Instant instant = odt.toInstant() ;

Converting ZonedDateTime.

// Storing
OffsetDateTime odt = zdt.toOffsetDateTime() ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = odt.atZone( z ) ; 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

In Python 3.3, added new method timestamp:

import datetime
seconds_since_epoch = datetime.datetime.now().timestamp()

Your question stated that you needed milliseconds, which you can get like this:

milliseconds_since_epoch = datetime.datetime.now().timestamp() * 1000

If you use timestamp on a naive datetime object, then it assumed that it is in the local timezone. Use timezone-aware datetime objects if this is not what you intend to happen.

Have you tried by setting the MIME type of your .m4v to "video/m4v" or "video/x-m4v" ?

Browsers might use the canPlayType method internally to check if a <source> is candidate to playback.

In Chrome, I have these results:

document.createElement("video").canPlayType("video/mp4"); // "maybe"
document.createElement("video").canPlayType("video/m4v"); // ""
document.createElement("video").canPlayType("video/x-m4v"); // "maybe"
