The C# / .NET engine we use for licence key generation is now maintained as open source:

https://github.com/appsoftware/.NET-Licence-Key-Generator.

It's based on a "Partial Key Verification" system which means only a subset of the key that you use to generate the key has to be compiled into your distributable. You create the keys your self, so the licence implementation is unique to your software.

As stated above, if your code can be decompiled, it's relatively easy to circumvent most licencing systems.

I realize that this answer is about 10 years late to the party.

A good software license key/serial number generator consists of more than just a string of random characters or a value from some curve generator. Using a limited alphanumeric alphabet, data can be embedded into a short string (e.g. XXXX-XXXX-XXXX-XXXX) that includes all kinds of useful information such as:

• Date created or the date the license expires
• Product ID, product classification, major and minor version numbers
• Custom bits like a hardware hash
• Per-user hash checksum bits (e.g. the user enters their email address along with the license key and both pieces of information are used to calculate/verify the hash).

The license key data is then encrypted and then encoded using the limited alphanumeric alphabet. For online validation, the license server holds the secrets for decrypting the information. For offline validation, the decryption secret(s) are included with the software itself along with the decryption/validation code. Obviously, offline validation means the software isn't secure against someone making a keygen.

Probably the hardest part about creating a license key is figuring out how to cram as much data as possible into as few bytes as possible. Remember that users will be entering in their license keys by hand, so every bit counts and users don't want to type extremely long, complex strings in. 16 to 25 character license keys are the most common and balance how much data can be placed into a key vs. user tolerance for entering the key to unlock the software. Slicing up bytes into chunks of bits allows for more information to be included but does increase code complexity of both the generator and validator.

Encryption is a complex topic. In general, standard encryption algorithms like AES have block sizes that don't align with the goal of keeping license key lengths short. Therefore, most developers making their own license keys end up writing their own encryption algorithms (an activity which is frequently discouraged) or don't encrypt keys at all, which guarantees that someone will write a keygen. Suffice it to say that good encryption is hard to do right and a decent understanding of how Feistel networks and existing ciphers work are prerequisites.

Verifying a key is a matter of decoding and decrypting the string, verifying the hash/checksum, checking the product ID and major and minor version numbers in the data, verifying that the license hasn't expired, and doing whatever other checks need to be performed.

Writing a keygen is a matter of knowing what a license key consists of and then producing the same output that the original key generator produces. If the algorithm for license key verification is included in and used by the software, then it is just a matter of creating software that does the reverse of the verification process.

To see what the entire process looks like, here is a blog post I recently wrote that goes over choosing the license key length, the data layout, the encryption algorithm, and the final encoding scheme:

https://cubicspot.blogspot.com/2020/03/adventuring-deeply-into-software-serial.html

A practical, real-world implementation of the key generator and key verifier from the blog post can be seen here:

https://github.com/cubiclesoft/php-misc/blob/master/support/serial_number.php

Documentation for the above class:

https://github.com/cubiclesoft/php-misc/blob/master/docs/serial_number.md

A production-ready open source license server that generates and manages license keys using the above serial number code can be found here:

https://github.com/cubiclesoft/php-license-server

The above license server supports both online and offline validation modes. A software product might start its existence with online only validation. When the software product is ready to retire and no longer supported, it can easily move to offline validation where all existing keys continue to work once the user upgrades to the very last version of the software that switches over to offline validation.

A live demo of how the above license server can be integrated into a website to sell software licenses plus an installable demo application can be found here (both the website and demo app are open source too):

https://license-server-demo.cubiclesoft.com/

Full disclosure: I'm the author of both the license server and the demo site software.

You are describing exactly how and why signing is used in public key cryptography. Note that it's very dangerous to sign (or encrypt) aritrary messages supplied by others - this allows attacks on the algorithms that could compromise your keys.

I'm going to piggyback a bit on @frankodwyer's great answer and dig a little deeper into online-based licensing. I'm the founder of Keygen, a licensing REST API built for developers.

Since you mentioned wanting 2 "types" of licenses for your application, i.e. a "full version" and a "trial version", we can simplify that and use a feature license model where you license specific features of your application (in this case, there's a "full" feature-set and a "trial" feature-set).

To start off, we could create 2 license types (called policies in Keygen) and whenever a user registers an account you can generate a "trial" license for them to start out (the "trial" license implements our "trial" feature policy), which you can use to do various checks within the app e.g. can user use Trial-Feature-A and Trial-Feature-B.

And building on that, whenever a user purchases your app (whether you're using PayPal, Stripe, etc.), you can generate a license implementing the "full" feature policy and associate it with the user's account. Now within your app you can check if the user has a "full" license that can do Pro-Feature-X and Pro-Feature-Y (by doing something like user.HasLicenseFor(FEATURE_POLICY_ID)).

I mentioned allowing your users to create user accounts—what do I mean by that? I've gone into this in detail in a couple other answers, but a quick rundown as to why I think this is a superior way to authenticate and identify your users:

1. User accounts let you associate multiple licenses and multiple machines to a single user, giving you insight into your customer's behavior and to prompt them for "in-app purchases" i.e. purchasing your "full" version (kind of like mobile apps).
2. We shouldn't require our customers to input long license keys, which are both tedious to input and hard to keep track of i.e. they get lost easily. (Try searching "lost license key" on Twitter!)
3. Customers are accustomed to using an email/password; I think we should do what people are used to doing so that we can provide a good user experience (UX).

Of course, if you don't want to handle user accounts and you want your users to input license keys, that's completely fine (and Keygen supports doing that as well). I'm just offering another way to go about handling that aspect of licensing and hopefully provide a nice UX for your customers.

Finally since you also mentioned that you want to update these licenses annually, you can set a duration on your policies so that "full" licenses will expire after a year and "trial" licenses last say 2 weeks, requiring that your users purchase a new license after expiration.

I could dig in more, getting into associating machines with users and things like that, but I thought I'd try to keep this answer short and focus on simply licensing features to your users.

step 1: click on the blue icon on taskbar. It is "SDK MANAGER". Then next click on the Appearance & Behaviour -> System Settings -> Android Sdk

step2: select on "Android SDK location" and choose edit option.It will prompt you update/install the components. Then start the download or update and this may take a while , all you have to do is wait patiently. "In case you have previously installed the sdk it will show that the sdk android sdk is installed"

step3: once this is done the program will compile fine ,and no error will exist whatsoever.

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

Changing an integer to a double

int abc=12; //setting up integer "abc"

System.out.println((double)abc); 

The code will output integer "abc" as a double, which means that it will display as "12.0". Notice how there is a decimal place, indicating that this precision digit has been stored.

Same with double if you want to change it back,

double number=13.94;

System.out.println((int)number); 

This code will print on one line, "number" as an integer. The output will be "13". Notice that the value has not been rounded up, the data has actually been omitted.

The delete command has no effect on regular variables, only properties. After the delete command the property doesn't have the value null, it doesn't exist at all.

If the property is an object reference, the delete command deletes the property but not the object. The garbage collector will take care of the object if it has no other references to it.

Example:

var x = new Object();
x.y = 42;

alert(x.y); // shows '42'

delete x; // no effect
alert(x.y); // still shows '42'

delete x.y; // deletes the property
alert(x.y); // shows 'undefined'

(Tested in Firefox.)

Just like most people have said, the main difference is the fact that it is wrapped in a jQuery object with the jQuery call vs the raw DOM object using straight JavaScript. The jQuery object will be able to do other jQuery functions with it of course but, if you just need to do simple DOM manipulation like basic styling or basic event handling, the straight JavaScript method is always a tad bit faster than jQuery since you don't have to load in an external library of code built on JavaScript. It saves an extra step.

I have found a pretty big difference in timing when testing in my browser.

I used the following script:

WARNING: running this will freeze your browser a bit, might even crash it.

var n = 10000000, i;_x000D_
i = n;_x000D_
console.time('selector');_x000D_
while (i --> 0){_x000D_
    $("body");_x000D_
}_x000D_
_x000D_
console.timeEnd('selector');_x000D_
_x000D_
i = n;_x000D_
console.time('element');_x000D_
while (i --> 0){_x000D_
    $(document.body);_x000D_
}_x000D_
_x000D_
console.timeEnd('element');

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

I did 10 million interactions, and those were the results (Chrome 65):

selector: 19591.97509765625ms
element: 4947.8759765625ms

Passing the element directly is around 4 times faster than passing the selector.

def nans(df): return df[df.isnull().any(axis=1)]

then when ever you need it you can type:

nans(your_dataframe)

I have to point out that there is a small but absolutely CRITICAL error in kalley's answer. I struggled with this for several hours before realizing:

Inside the function, what you are returning is a comparison, and thus something like this would be more correct:

$desired_object = $food->filter(function($item) {
    return ($item->id **==** 24);
})->first();

You cannot calculate the differences separately ... what difference would that yield for 7:59 and 8:00 o'clock? Try

import time
time.time()

which gives you the seconds since the start of the epoch.

You can then get the intermediate time with something like

timestamp1 = time.time()
# Your code here
timestamp2 = time.time()
print "This took %.2f seconds" % (timestamp2 - timestamp1)

$("#YourElementID").css("display","block");

Edit: or as dave thieben points out in his comment below, you can do this as well:

$("#YourElementID").css({ display: "block" });

Yes you can.

You just need to understand what they are for, the class is more general and can be used several times, the id (is like your id's) you can use it only once.

This excellent tutorial helped me with that:

The Difference Between ID and Class

Though it's not an exact answer to your question I'm sure it will help you a lot!

Good luck!

EDIT: Reading your question, I just want to clarify that:

<div class="x" id="y">
    --
</div>

And that if you want to "use them" in CSS for styling purposes you should do as David Says: #x.y { }

This works for me:

plt.xticks(rotation=90)

The angular way is shown in the angular docs :)

https://docs.angularjs.org/api/ng/directive/ngReadonly

Here is the example they use:

<body>
    Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
    <input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>

Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).

So basically in your case you would want to do something like below or check out this working example.

<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>

ObjectIDs are objects so if you just compare them with == you're comparing their references. If you want to compare their values you need to use the ObjectID.equals method:

if (results.userId.equals(AnotherMongoDocument._id)) {
    ...
}

It works, but I wouldn't do it if I were you. You don't seem to be deleting that heap data when you're done, which means that you've created a memory leak. The C++ compiler takes care of ensuring that exception data is kept alive even as the stack is popped, so don't feel that you need to use the heap.

Incidentally, throwing a std::string isn't the best approach to begin with. You'll have a lot more flexibility down the road if you use a simple wrapper object. It may just encapsulate a string for now, but maybe in future you will want to include other information, like some data which caused the exception or maybe a line number (very common, that). You don't want to change all of your exception handling in every spot in your code-base, so take the high road now and don't throw raw objects.

You need to write it this way

<div 
    className="player"
    style={{ position: "absolute" }}
    onKeyDown={this.onKeyPressed}
    tabIndex="0"
  >

If onKeyPressed is not bound to this, then try to rewrite it using arrow function or bind it in the component constructor.

Taking it further you could even parse on the fly

e.g.

& "my.exe" | %{
    if ($_ -match 'OK')
    { Write-Host $_ -f Green }
    else if ($_ -match 'FAIL|ERROR')
    { Write-Host $_ -f Red }
    else 
    { Write-Host $_ }
}

All of the responses refer to BootStrap 2 typeahead, which is no longer present in BootStrap 3.

For anyone else directed here looking for an AJAX example using the new post-Bootstrap Twitter typeahead.js, here's a working example. The syntax is a little different:

$('#mytextquery').typeahead({
  hint: true,
  highlight: true,
  minLength: 1
},
{
  limit: 12,
  async: true,
  source: function (query, processSync, processAsync) {
    processSync(['This suggestion appears immediately', 'This one too']);
    return $.ajax({
      url: "/ajax/myfilter.php", 
      type: 'GET',
      data: {query: query},
      dataType: 'json',
      success: function (json) {
        // in this example, json is simply an array of strings
        return processAsync(json);
      }
    });
  }
});

This example uses both synchronous (the call to processSync) and asynchronous suggestion, so you'd see some options appear immediately, then others are added. You can just use one or the other.

There are lots of bindable events and some very powerful options, including working with objects rather than strings, in which case you'd use your own custom display function to render your items as text.

Here's a slghtly different take using javascript's native confirm functionality and a custom Angular directive. It's super flexible and pretty lightweight:

Usage:

<button (hrsAreYouSure) (then)="confirm(arg1)" (else)="cancel(arg2)">
  This will execute confirm if user presses Ok on the confirmation dialog, or cancel if they
  hit Cancel
</button>

Directive:

import {Directive, ElementRef, EventEmitter, Inject, OnInit, Output} from '@angular/core';

@Directive({
  selector: '[hrsAreYouSure]'
})

export class AreYouSureDirective implements OnInit {

  @Output() then = new EventEmitter<boolean>();
  @Output() else = new EventEmitter<boolean>();

  constructor(@Inject(ElementRef) private element: ElementRef) { }

  ngOnInit(): void {
    const directive = this;
    this.element.nativeElement.onclick = function() {
      const result = confirm('Are you sure?');
      if (result) {
        directive.then.emit(true);
      } else {
        directive.else.emit(true);
      }
    };
  }
}

You must create a new anonymous type:

 select new { op, pg }

Refer to the official guide.

I disagree with this kind of path

GET /companies/{companyId}/departments

If you want to get departments, I think it's better to use a /departments resource

GET /departments?companyId=123

I suppose you have a companies table and a departments table then classes to map them in the programming language you use. I also assume that departments could be attached to other entities than companies, so a /departments resource is straightforward, it's convenient to have resources mapped to tables and also you don't need as many endpoints since you can reuse

GET /departments?companyId=123

for any kind of search, for instance

GET /departments?name=xxx
GET /departments?companyId=123&name=xxx
etc.

If you want to create a department, the

POST /departments

resource should be used and the request body should contain the company ID (if the department can be linked to only one company).

please try this regex (allow only Alphabets and space)

"[a-zA-Z][a-zA-Z ]*"

if you want it for IOS then,

NSString *yourstring = @"hello";

NSString *Regex = @"[a-zA-Z][a-zA-Z ]*";
NSPredicate *TestResult = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",Regex];

if ([TestResult evaluateWithObject:yourstring] == true)
{
    // validation passed
}
else
{
    // invalid name
}

Here is a solution using Guava

private User findUserByName(List<User> userList, final String name) {
    Optional<User> userOptional =
            FluentIterable.from(userList).firstMatch(new Predicate<User>() {
                @Override
                public boolean apply(@Nullable User input) {
                    return input.getName().equals(name);
                }
            });
    return userOptional.isPresent() ? userOptional.get() : null; // return user if found otherwise return null if user name don't exist in user list
}

From your code it would appear that you are trying to measure how long a computation took (as opposed to trying to figure out what the current time is).

In that case, you need to call currentTimeMillis before and after the computation, take the difference, and divide the result by 1000 to convert milliseconds to seconds.

These specific lines are the usual wrapper for jQuery plugins:

"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."

(function( $ ){
  $.fn.myPlugin = function() {
    // Do your awesome plugin stuff here
  };
})( jQuery );

From http://docs.jquery.com/Plugins/Authoring

JS only - no need for jquery

Simply create an input element and trigger the click.

var input = document.createElement('input');
input.type = 'file';
input.click();

This is the most basic, pop a select-a-file dialog, but its no use for anything without handling the selected file...

Handling the files

Adding an onchange event to the newly created input would allow us to do stuff once the user has selected the file.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 
   var file = e.target.files[0]; 
}

input.click();

At the moment we have the file variable storing various information :

file.name // the file's name including extension
file.size // the size in bytes
file.type // file type ex. 'application/pdf'

Great!

But, what if we need the content of the file?

In order to get to the actual content of the file, for various reasons. place an image, load into canvas, create a window with Base64 data url, etc. we would need to use the FileReader API

We would create an instance of the FileReader, and load our user selected file reference to it.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsText(file,'UTF-8');

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      console.log( content );
   }

}

input.click();

Trying pasting the above code into your devtool's console window, it should produce a select-a-file dialog, after selecting the file, the console should now print the contents of the file.

Example - "Stackoverflow's new background image!"

Let's try to create a file select dialog to change stackoverflows background image to something more spicy...

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsDataURL(file); // this is reading as data url

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      document.querySelector('#content').style.backgroundImage = 'url('+ content +')';
   }

}

input.click();

open devtools, and paste the above code into console window, this should pop a select-a-file dialog, upon selecting an image, stackoverflows content box background should change to the image selected.

Cheers!

I just used the following code:

<form method="post">
    <input id="user1" value="user1"  name="invite[]" type="checkbox">
    <input id="user2" value="user2"  name="invite[]" type="checkbox">
    <input type="submit">
</form>

<?php
    if(isset($_POST['invite'])){
        $invite = $_POST['invite'];
        print_r($invite);
    }
?>

When I checked both boxes, the output was:

Array ( [0] => user1 [1] => user2 )

I know this doesn't directly answer your question, but it gives you a working example to reference and hopefully helps you solve the problem.

You must set CHMOD +x (execute for *.sh or *.bat files). For example, I am using macOS

cd /Users/donhuvy/Documents/tools/apache-tomcat-9.0.12/bin
sudo chmod +x *.sh

Then IntelliJ IDEA, and Apache Tomcat running or debugging just good.

Well actually...

I wouldn't have the Fragment try to finish the Activity. That places too much authority on the Fragment in my opinion. Instead, I would use the guide here: http://developer.android.com/training/basics/fragments/communicating.html

Have the Fragment define an interface which the Activity must implement. Make a call up to the Activity, then let the Activity decide what to do with the information. If the activity wishes to finish itself, then it can.

UPDATE: Somebody just won't take no as the answer, and I like it, very much, especially to this particular question.

GOOD NEWS, There is a way now --

The solution is Rocker: https://github.com/grammarly/rocker

John Yani said, "IMO, it solves all the weak points of Dockerfile, making it suitable for development."

Rocker

https://github.com/grammarly/rocker

By introducing new commands, Rocker aims to solve the following use cases, which are painful with plain Docker:

1. Mount reusable volumes on build stage, so dependency management tools may use cache between builds.
2. Share ssh keys with build (for pulling private repos, etc.), while not leaving them in the resulting image.
3. Build and run application in different images, be able to easily pass an artifact from one image to another, ideally have this logic in a single Dockerfile.
4. Tag/Push images right from Dockerfiles.
5. Pass variables from shell build command so they can be substituted to a Dockerfile.

And more. These are the most critical issues that were blocking our adoption of Docker at Grammarly.

Update: Rocker has been discontinued, per the official project repo on Github

As of early 2018, the container ecosystem is much more mature than it was three years ago when this project was initiated. Now, some of the critical and outstanding features of rocker can be easily covered by docker build or other well-supported tools, though some features do remain unique to rocker. See https://github.com/grammarly/rocker/issues/199 for more details.

Use the -S option to gcc (or g++).

gcc -S helloworld.c

This will run the preprocessor (cpp) over helloworld.c, perform the initial compilation and then stop before the assembler is run.

By default this will output a file helloworld.s. The output file can be still be set by using the -o option.

gcc -S -o my_asm_output.s helloworld.c

Of course this only works if you have the original source. An alternative if you only have the resultant object file is to use objdump, by setting the --disassemble option (or -d for the abbreviated form).

objdump -S --disassemble helloworld > helloworld.dump

This option works best if debugging option is enabled for the object file (-g at compilation time) and the file hasn't been stripped.

Running file helloworld will give you some indication as to the level of detail that you will get by using objdump.

Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:

$('td').click(function(){
   var row_index = $(this).closest("tr").index();
   var col_index = $(this).index();
});

Very often this error appears if you use incompatible versions of Selenium and ChromeDriver.

The id should be placed inside of componentWillMount (update for 2018) constructor, not render. Putting it in render will re-generate new ids unnecessarily.

If you're using underscore or lodash, there is a uniqueId function, so your resulting code should be something like:

constructor(props) {
    super(props);
    this.id = _.uniqueId("prefix-");
}

render() { 
  const id = this.id;
  return (
    <div>
        <input id={id} type="checkbox" />
        <label htmlFor={id}>label</label>
    </div>
  );
}

2019 Hooks update:

import React, { useState } from 'react';
import _uniqueId from 'lodash/uniqueId';

const MyComponent = (props) => {
  // id will be set once when the component initially renders, but never again
  // (unless you assigned and called the second argument of the tuple)
  const [id] = useState(_uniqueId('prefix-'));
  return (
    <div>
      <input id={id} type="checkbox" />
      <label htmlFor={id}>label</label>
    </div>
  );
}

You don't need underscore, just use built-in map:

var string = 'Hello World!';_x000D_
_x000D_
document.write(string.split('').map(function(c) { return c.charCodeAt(); }));

For the completeness's sake.

'Killing a thread' is not the right phrase to use. Here is one way we can implement graceful completion/exit of the thread on will:

Runnable which I used:

class TaskThread implements Runnable {

    boolean shouldStop;

    public TaskThread(boolean shouldStop) {
        this.shouldStop = shouldStop;
    }

    @Override
    public void run() {

        System.out.println("Thread has started");

        while (!shouldStop) {
            // do something
        }

        System.out.println("Thread has ended");

    }

    public void stop() {
        shouldStop = true;
    }

}

The triggering class:

public class ThreadStop {

    public static void main(String[] args) {

        System.out.println("Start");

        // Start the thread
        TaskThread task = new TaskThread(false);
        Thread t = new Thread(task);
        t.start();

        // Stop the thread
        task.stop();

        System.out.println("End");

    }

}

Please just write a static method somewhere and write:

if( isSizeBetween(orderBean.getFiles(), 0, 5) ){
    // do your stuff 
}

Python 3: logging

Instead of using the basic print() function, the more flexible logging module can be used to log the exception. The logging module offers a lot extra functionality, e.g. logging messages into a given log file, logging messages with timestamps and additional information about where the logging happened. (For more information check out the official documentation.)

Logging an exception can be done with the module-level function logging.exception() like so:

import logging

try:
    1/0
except BaseException:
    logging.exception("An exception was thrown!")

Output:

ERROR:root:An exception was thrown!
Traceback (most recent call last):
  File ".../Desktop/test.py", line 4, in <module>
    1/0
ZeroDivisionError: division by zero 

Notes:

• the function logging.exception() should only be called from an exception handler

• the logging module should not be used inside a logging handler to avoid a RecursionError (thanks @PrakharPandey)

Alternative log-levels

It's also possible to log the exception with another log-level by using the keyword argument exc_info=True like so:

logging.debug("An exception was thrown!", exc_info=True)
logging.info("An exception was thrown!", exc_info=True)
logging.warning("An exception was thrown!", exc_info=True)

Toad for MySQL by Quest is free for non-commercial use. I really like the interface and it's quite powerful if you have several databases to work with (for example development, test and production servers).

From the website:

Toad® for MySQL is a freeware development tool that enables you to rapidly create and execute queries, automate database object management, and develop SQL code more efficiently. It provides utilities to compare, extract, and search for objects; manage projects; import/export data; and administer the database. Toad for MySQL dramatically increases productivity and provides access to an active user community.

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

Once a dom element is created, the tag is immutable, I believe. You'd have to do something like this:

$(this).replaceWith($('<h5>' + this.innerHTML + '</h5>'));

Yes - older POSIX standards defined usleep(), so this is available on Linux:

int usleep(useconds_t usec);

DESCRIPTION

The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers.

usleep() takes microseconds, so you will have to multiply the input by 1000 in order to sleep in milliseconds.

usleep() has since been deprecated and subsequently removed from POSIX; for new code, nanosleep() is preferred:

#include <time.h>

int nanosleep(const struct timespec *req, struct timespec *rem);

DESCRIPTION

nanosleep() suspends the execution of the calling thread until either at least the time specified in *req has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process.

The structure timespec is used to specify intervals of time with nanosecond precision. It is defined as follows:

struct timespec {
    time_t tv_sec;        /* seconds */
    long   tv_nsec;       /* nanoseconds */
};

An example msleep() function implemented using nanosleep(), continuing the sleep if it is interrupted by a signal:

#include <time.h>
#include <errno.h>    

/* msleep(): Sleep for the requested number of milliseconds. */
int msleep(long msec)
{
    struct timespec ts;
    int res;

    if (msec < 0)
    {
        errno = EINVAL;
        return -1;
    }

    ts.tv_sec = msec / 1000;
    ts.tv_nsec = (msec % 1000) * 1000000;

    do {
        res = nanosleep(&ts, &ts);
    } while (res && errno == EINTR);

    return res;
}

add delim_whitespace=True argument, it's faster than regex.

At the time of this writing, there is no official support for TensorFlow with Python 3.6 on Windows. The recommendation is to build TensorFlow yourself.

Some people have already done this and provide *.whl files that you can directly install with pip. These are unofficial, so use at your own risk:

• http://www.lfd.uci.edu/%7Egohlke/pythonlibs/#tensorflow

You can simply download them and install them with pip install <filename>.whl.

See also this GitHub comment.

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

You can get a shorter version by using sys.path[0].

os.chdir(sys.path[0])

From http://docs.python.org/library/sys.html#sys.path

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter

The remove operation on a list is given a value to remove. It searches the list to find an item with that value and deletes the first matching item it finds. It is an error if there is no matching item, raises a ValueError.

>>> x = [1, 0, 0, 0, 3, 4, 5]
>>> x.remove(4)
>>> x
[1, 0, 0, 0, 3, 5]
>>> del x[7]
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    del x[7]
IndexError: list assignment index out of range

The del statement can be used to delete an entire list. If you have a specific list item as your argument to del (e.g. listname[7] to specifically reference the 8th item in the list), it'll just delete that item. It is even possible to delete a "slice" from a list. It is an error if there index out of range, raises a IndexError.

>>> x = [1, 2, 3, 4]
>>> del x[3]
>>> x
[1, 2, 3]
>>> del x[4]
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    del x[4]
IndexError: list assignment index out of range

The usual use of pop is to delete the last item from a list as you use the list as a stack. Unlike del, pop returns the value that it popped off the list. You can optionally give an index value to pop and pop from other than the end of the list (e.g listname.pop(0) will delete the first item from the list and return that first item as its result). You can use this to make the list behave like a queue, but there are library routines available that can provide queue operations with better performance than pop(0) does. It is an error if there index out of range, raises a IndexError.

>>> x = [1, 2, 3] 
>>> x.pop(2) 
3 
>>> x 
[1, 2]
>>> x.pop(4)
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    x.pop(4)
IndexError: pop index out of range

Try this in SQL Server 2008:

select *
from some_table t
where convert(time,t.some_datetime_column) = '5pm'

If you want take a random datetime value and adjust it so the time component is 5pm, then in SQL Server 2008 there are a number of ways. First you need start-of-day (e.g., 2011-09-30 00:00:00.000).

• One technique that works for all versions of Microsoft SQL Server as well as all versions of Sybase is to use convert/3 to convert the datetime value to a varchar that lacks a time component and then back into a datetime value:

  select convert(datetime,convert(varchar,current_timestamp,112),112)
  

The above gives you start-of-day for the current day.

• In SQL Server 2008, though, you can say something like this:

  select start_of_day =               t.some_datetime_column
                      - convert(time, t.some_datetime_column ) ,
  from some_table t
  

  which is likely faster.

Once you have start-of-day, getting to 5pm is easy. Just add 17 hours to your start-of-day value:

select five_pm = dateadd(hour,17, t.some_datetime_column
                   - convert(time,t.some_datetime_column)
                   )
from some_table t

You should initialize variables to None and then check it:

var1 = None
if var1 is None:
    var1 = 4

Which can be written in one line as:

var1 = 4 if var1 is None else var1

or using shortcut (but checking against None is recommended)

var1 = var1 or 4

alternatively if you will not have anything assigned to variable that variable name doesn't exist and hence using that later will raise NameError, and you can also use that knowledge to do something like this

try:
    var1
except NameError:
    var1 = 4

but I would advise against that.

Here is the Kotlin extension I am using:

fun Spinner.setItem(list: Array<CharSequence>, value: String) {
    val index = list.indexOf(value)
    this.post { this.setSelection(index) }
}

Usage:

spinnerPressure.setItem(resources.getTextArray(R.array.array_pressure), pressureUnit)

If you are popping it in the DOM then try wrapping it in

<pre>
    <code>{JSON.stringify(REPLACE_WITH_OBJECT, null, 4)}</code>
</pre>

makes a little easier to visually parse.

For this you can use limit

select *
from scores
order by score desc
limit 10

If performance is important (when is it not ;-) look for an index on score.

Starting with version 8.4, you can also use the standard (SQL:2008) fetch first

select *
from scores
order by score desc
fetch first 10 rows only

As @Raphvanns pointed out, this will give you the first 10 rows literally. To remove duplicate values, you have to select distinct rows, e.g.

select distinct *
from scores
order by score desc
fetch first 10 rows only

SQL Fiddle

Just call the "type" built in using three parameters, like this:

ClassName = type("ClassName", (Base1, Base2,...), classdictionary)

update as stated in the comment bellow this is not the answer to this question at all. I will keep it undeleted, since there are hints some people get here trying to dynamically create classes - which is what the line above does.

To create an object of a class one has a reference too, as put in the accepted answer, one just have to call the class:

instance = ClassObject()

The mechanism for instantiation is thus:

Python does not use the new keyword some languages use - instead it's data model explains the mechanism used to create an instantance of a class when it is called with the same syntax as any other callable:

Its class' __call__ method is invoked (in the case of a class, its class is the "metaclass" - which is usually the built-in type). The normal behavior of this call is to invoke the (pseudo) static __new__ method on the class being instantiated, followed by its __init__. The __new__ method is responsible for allocating memory and such, and normally is done by the __new__ of object which is the class hierarchy root.

So calling ClassObject() invokes ClassObject.__class__.call() (which normally will be type.__call__) this __call__ method will receive ClassObject itself as the first parameter - a Pure Python implementation would be like this: (the cPython version is of course, done in C, and with lots of extra code for cornercases and optimizations)

class type:
    ...
    def __call__(cls, *args, **kw):
          constructor = getattr(cls, "__new__")
          instance = constructor(cls) if constructor is object.__new__ else constructor(cls, *args, **kw)
          instance.__init__(cls, *args, **kw)
          return instance

(I don't recall seeing on the docs the exact justification (or mechanism) for suppressing extra parameters to the root __new__ and passing it to other classes - but it is what happen "in real life" - if object.__new__ is called with any extra parameters it raises a type error - however, any custom implementation of a __new__ will get the extra parameters normally)

Python resolves your variables with -- generally -- three namespaces available.

At any time during execution, there are at least three nested scopes whose namespaces are directly accessible: the innermost scope, which is searched first, contains the local names; the namespaces of any enclosing functions, which are searched starting with the nearest enclosing scope; the middle scope, searched next, contains the current module's global names; and the outermost scope (searched last) is the namespace containing built-in names.

There are two functions: globals and locals which show you the contents two of these namespaces.

Namespaces are created by packages, modules, classes, object construction and functions. There aren't any other flavors of namespaces.

In this case, the call to a function named x has to be resolved in the local name space or the global namespace.

Local in this case, is the body of the method function Foo.spam.

Global is -- well -- global.

The rule is to search the nested local spaces created by method functions (and nested function definitions), then search global. That's it.

There are no other scopes. The for statement (and other compound statements like if and try) don't create new nested scopes. Only definitions (packages, modules, functions, classes and object instances.)

Inside a class definition, the names are part of the class namespace. code2, for instance, must be qualified by the class name. Generally Foo.code2. However, self.code2 will also work because Python objects look at the containing class as a fall-back.

An object (an instance of a class) has instance variables. These names are in the object's namespace. They must be qualified by the object. (variable.instance.)

From within a class method, you have locals and globals. You say self.variable to pick the instance as the namespace. You'll note that self is an argument to every class member function, making it part of the local namespace.

See Python Scope Rules, Python Scope, Variable Scope.

DataSource – setCurrentSchema

When instantiating a DataSource implementation, look for a method to set the current/default schema.

For example, on the PGSimpleDataSource class call setCurrentSchema.

org.postgresql.ds.PGSimpleDataSource dataSource = new org.postgresql.ds.PGSimpleDataSource ( );
dataSource.setServerName ( "localhost" );
dataSource.setDatabaseName ( "your_db_here_" );
dataSource.setPortNumber ( 5432 );
dataSource.setUser ( "postgres" );
dataSource.setPassword ( "your_password_here" );
dataSource.setCurrentSchema ( "your_schema_name_here_" );  // <----------

If you leave the schema unspecified, Postgres defaults to a schema named public within the database. See the manual, section 5.9.2 The Public Schema. To quote hat manual:

In the previous sections we created tables without specifying any schema names. By default such tables (and other objects) are automatically put into a schema named “public”. Every new database contains such a schema.

This fixed my problem.. All I needed to do was to downgrade my google-services plugin in buildscript in the build.gradle(Project) level file as follows

buildscript{
     dependencies {
        // From =>
        classpath 'com.google.gms:google-services:4.3.0'
        // To =>
        classpath 'com.google.gms:google-services:4.2.0'
        // Add dependency
        classpath 'io.fabric.tools:gradle:1.28.1'
    }
}

if you are sure that you have uploaded the content of key.pub into GitLab, then: 1- Open Git Bash "Not CMD" 2- Browse to Solution Folder "CD Path" 3- Type Git Init 4- Type Git Add . 4- Type Git Commit 6- Type Git Push

and it will work.. another hint: make sure the path of the file where you copied the key is correct and equivalent to the same path it showed on CMD when creating the keys

Since .NET 4.5 you can use combination of async and await with Progress for sending updates to UI thread:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

public void DoWork(IProgress<int> progress)
{
    // This method is executed in the context of
    // another thread (different than the main UI thread),
    // so use only thread-safe code
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);

        // Use progress to notify UI thread that progress has
        // changed
        if (progress != null)
            progress.Report((j + 1) * 100 / 100000);
    }
}

private async void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;

    var progress = new Progress<int>(v =>
    {
        // This lambda is executed in context of UI thread,
        // so it can safely update form controls
        progressBar1.Value = v;
    });

    // Run operation in another thread
    await Task.Run(() => DoWork(progress));

    // TODO: Do something after all calculations
}

Tasks are currently the preferred way to implement what BackgroundWorker does.

Tasks and Progress are explained in more detail here:

• Async in 4.5: Enabling Progress and Cancellation in Async APIs
• Reporting Progress from Async Tasks by Stephen Cleary
• Task parallel library replacement for BackgroundWorker?

The best way for me was to put it in a hidden div in php blade

<div hidden id="token">{{$token}}</div>

then call it in javascript as a constant to avoid undefined var errors

const token = document.querySelector('div[id=token]').textContent

// console.log(token)

building on top of above answers, here is what I plagiarized and came up with. Also added memory logging.

#import <mach/mach.h>

#else

I was having a similar issue and used $stateParams instead of routeParam

You can do it like this

$(function(){_x000D_
  $("tr").find("td:eq(0)").css("color","red");_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<table>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
</table>

This is certainly possible. This works in Chrome, Firefox, and IE 11 (and probably others).

focus();
var listener = window.addEventListener('blur', function() {
    if (document.activeElement === document.getElementById('iframe')) {
        // clicked
    }
    window.removeEventListener('blur', listener);
});

Caveat: This only detects the first click. As I understand, that is all you want.

I ran into this problem in a legacy application, and it was difficult to identify where what was printed. I helped myself with this hack:

# encoding_utf8.py
import codecs
import builtins


def print_utf8(text, **kwargs):
    print(str(text).encode('utf-8'), **kwargs)


def print_utf8(fn):
    def print_fn(*args, **kwargs):
        return fn(str(*args).encode('utf-8'), **kwargs)
    return print_fn


builtins.print = print_utf8(print)

On top of my script, test.py:

import encoding_utf8
string = 'Axwell ? Ingrosso'
print(string)

Note that this changes ALL calls to print to use an encoding, so your console will print this:

$ python test.py
b'Axwell \xce\x9b Ingrosso'

I the following error message when faced this same problem:

The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

Solved when I used the same property name, it worked.

(...)

join enderecoST in db.PessoaEnderecos on 
    new 
      {  
         CD_PESSOA          = nf.CD_PESSOA_ST, 
         CD_ENDERECO_PESSOA = nf.CD_ENDERECO_PESSOA_ST 
      } equals 
    new 
    { 
         enderecoST.CD_PESSOA, 
         enderecoST.CD_ENDERECO_PESSOA 
    } into eST

(...)

This is my solution, it supports keySelectors of different types:

public static IEnumerable<TSource> DistinctBy<TSource>(this IEnumerable<TSource> source, params Func<TSource, object>[] keySelectors)
{
    // initialize the table
    var seenKeysTable = keySelectors.ToDictionary(x => x, x => new HashSet<object>());

    // loop through each element in source
    foreach (var element in source)
    {
        // initialize the flag to true
        var flag = true;

        // loop through each keySelector a
        foreach (var (keySelector, hashSet) in seenKeysTable)
        {                    
            // if all conditions are true
            flag = flag && hashSet.Add(keySelector(element));
        }

        // if no duplicate key was added to table, then yield the list element
        if (flag)
        {
            yield return element;
        }
    }
}

To use it:

list.DistinctBy(d => d.CategoryId, d => d.CategoryName)

Apply the below code where you want to make code to exit application.

System.Windows.Forms.Application.Exit( )

You can try using parentheses around the OR expressions to make sure your query is interpreted correctly, or more concisely, use IN:

SELECT ads.*, location.county 
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1 
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)

After Spending quite a bit of time looking into this, i came up with the solution for this; In this solution i am not using the Basic authentication but instead went with the oAuth authentication protocol. But to use Basic authentication you should be able to specify this in the "setHeaderRequest" with minimal changes to the rest of the code example. I hope this will be able to help someone else in the future:

var token_ // variable will store the token
var userName = "clientID"; // app clientID
var passWord = "secretKey"; // app clientSecret
var caspioTokenUrl = "https://xxx123.caspio.com/oauth/token"; // Your application token endpoint  
var request = new XMLHttpRequest(); 

function getToken(url, clientID, clientSecret) {
    var key;           
    request.open("POST", url, true); 
    request.setRequestHeader("Content-type", "application/json");
    request.send("grant_type=client_credentials&client_id="+clientID+"&"+"client_secret="+clientSecret); // specify the credentials to receive the token on request
    request.onreadystatechange = function () {
        if (request.readyState == request.DONE) {
            var response = request.responseText;
            var obj = JSON.parse(response); 
            key = obj.access_token; //store the value of the accesstoken
            token_ = key; // store token in your global variable "token_" or you could simply return the value of the access token from the function
        }
    }
}
// Get the token
getToken(caspioTokenUrl, userName, passWord);

If you are using the Caspio REST API on some request it may be imperative that you to encode the paramaters for certain request to your endpoint; see the Caspio documentation on this issue;

NOTE: encodedParams is NOT used in this example but was used in my solution.

Now that you have the token stored from the token endpoint you should be able to successfully authenticate for subsequent request from the caspio resource endpoint for your application

function CallWebAPI() {
    var request_ = new XMLHttpRequest();        
    var encodedParams = encodeURIComponent(params);
    request_.open("GET", "https://xxx123.caspio.com/rest/v1/tables/", true);
    request_.setRequestHeader("Authorization", "Bearer "+ token_);
    request_.send();
    request_.onreadystatechange = function () {
        if (request_.readyState == 4 && request_.status == 200) {
            var response = request_.responseText;
            var obj = JSON.parse(response); 
            // handle data as needed... 

        }
    }
} 

This solution does only considers how to successfully make the authenticated request using the Caspio API in pure javascript. There are still many flaws i am sure...

When Spring loads your bean definitions, and has been configured to look for @Transactional annotations, it will create these proxy objects around your actual bean. These proxy objects are instances of classes that are auto-generated at runtime. The default behaviour of these proxy objects when a method is invoked is just to invoke the same method on the "target" bean (i.e. your bean).

However, the proxies can also be supplied with interceptors, and when present these interceptors will be invoked by the proxy before it invokes your target bean's method. For target beans annotated with @Transactional, Spring will create a TransactionInterceptor, and pass it to the generated proxy object. So when you call the method from client code, you're calling the method on the proxy object, which first invokes the TransactionInterceptor (which begins a transaction), which in turn invokes the method on your target bean. When the invocation finishes, the TransactionInterceptor commits/rolls back the transaction. It's transparent to the client code.

As for the "external method" thing, if your bean invokes one of its own methods, then it will not be doing so via the proxy. Remember, Spring wraps your bean in the proxy, your bean has no knowledge of it. Only calls from "outside" your bean go through the proxy.

Does that help?

If installed as an admin, use:-

uname - admin

All the languages you've mentioned are Turing Complete, so in theory there is nothing one can do and another can't. In practice of course, there are differences, especially in productivity and efficiency. Compared to C, C++ and Java, which are static typed, Python is a dynamic language and can help you write the same code in significantly fewer lines. Python has a moto "batteries included", which means that the standard library offers all the things needed to build a complex application. Other languages would need external libraries for this. On top of this, since Python is an old and mature language (older than Java), many external libraries (for game development and scientific calculations just to mention a few) have been evolved. So Python can be used to program desktop applications and in fact in some cases more efficiently than other traditional languages.

Python is also a scripting language. This means that you can easily and quickly write scripts and simple tests with it.

More recently python is also used for web frameworks. Since there is a big code base and many python programmers, this was a logical thing to do. These web frameworks follow the practice mainly introduced by Ruby on Rails.

The most elegant way to find percentages across columns or index is to use pd.crosstab.

Sample Data

df = pd.DataFrame({'state': ['CA', 'WA', 'CO', 'AZ'] * 3,
               'office_id': list(range(1, 7)) * 2,
               'sales': [np.random.randint(100000, 999999) for _ in range(12)]})

The output dataframe is like this

print(df)

        state   office_id   sales
    0   CA  1   764505
    1   WA  2   313980
    2   CO  3   558645
    3   AZ  4   883433
    4   CA  5   301244
    5   WA  6   752009
    6   CO  1   457208
    7   AZ  2   259657
    8   CA  3   584471
    9   WA  4   122358
    10  CO  5   721845
    11  AZ  6   136928

Just specify the index, columns and the values to aggregate. The normalize keyword will calculate % across index or columns depending upon the context.

result = pd.crosstab(index=df['state'], 
                     columns=df['office_id'], 
                     values=df['sales'], 
                     aggfunc='sum', 
                     normalize='index').applymap('{:.2f}%'.format)




print(result)
office_id   1   2   3   4   5   6
state                       
AZ  0.00%   0.20%   0.00%   0.69%   0.00%   0.11%
CA  0.46%   0.00%   0.35%   0.00%   0.18%   0.00%
CO  0.26%   0.00%   0.32%   0.00%   0.42%   0.00%
WA  0.00%   0.26%   0.00%   0.10%   0.00%   0.63%

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

I believe the Id column in your SQL Table isn't a identity column.

While waiting for the adoption of CSS3 targeting…

While waiting for the adoption of CSS3 targeting by the major browsers, one could run the following sed command once the (X)HTML has been created:

sed -i 's|href="http|target="_blank" href="http|g' index.html

It will add target="_blank" to all external hyperlinks. Variations are also possible.

EDIT

I use this at the end of the makefile which generates every web page on my site.

The below programme will help you drop duplicates on whole , or if you want to drop duplicates based on certain columns , you can even do that:

import org.apache.spark.sql.SparkSession

object DropDuplicates {
def main(args: Array[String]) {
val spark =
  SparkSession.builder()
    .appName("DataFrame-DropDuplicates")
    .master("local[4]")
    .getOrCreate()

import spark.implicits._

// create an RDD of tuples with some data
val custs = Seq(
  (1, "Widget Co", 120000.00, 0.00, "AZ"),
  (2, "Acme Widgets", 410500.00, 500.00, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (4, "Widgets R Us", 410500.00, 0.0, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (5, "Ye Olde Widgete", 500.00, 0.0, "MA"),
  (6, "Widget Co", 12000.00, 10.00, "AZ")
)
val customerRows = spark.sparkContext.parallelize(custs, 4)

// convert RDD of tuples to DataFrame by supplying column names
val customerDF = customerRows.toDF("id", "name", "sales", "discount", "state")

println("*** Here's the whole DataFrame with duplicates")

customerDF.printSchema()

customerDF.show()

// drop fully identical rows
val withoutDuplicates = customerDF.dropDuplicates()

println("*** Now without duplicates")

withoutDuplicates.show()

// drop fully identical rows
val withoutPartials = customerDF.dropDuplicates(Seq("name", "state"))

println("*** Now without partial duplicates too")

withoutPartials.show()

 }
 }

All the above is basically correct. One can check it. Just write a short method

public static void Main()
{
    var s = "a string";
}

compile it and open .exe with ildasm to see

.method private hidebysig static void  Main(string[] args) cil managed
{
  .entrypoint
  // Code size       8 (0x8)
  .maxstack  1
  .locals init ([0] string s)
  IL_0000:  nop
  IL_0001:  ldstr      "a string"
  IL_0006:  stloc.0
  IL_0007:  ret
} // end of method Program::Main

then change var to string and String, compile, open with ildasm and see IL does not change. It also shows the creators of the language prefer just string when difining variables (spoiler: when calling members they prefer String).

I had this problem when trying to consume a value returned from a stored procedure.

console.log(result[0]);

would output "[ RowDataPacket { datetime: '2019-11-15 16:37:05' } ]".

I found that

console.log(results[0][0].datetime);

Gave me the value I wanted.

I'm not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

Your CarBootSaleList class is not a list. It is a class that contain a list.

You have three options:

Make your CarBootSaleList object implement IEnumerable

or

make your CarBootSaleList inherit from List<CarBootSale>

or

if you are lazy this could almost do the same thing without extra coding

List<List<CarBootSale>>

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

With template literals, you can use multiple spaces or multi-line strings and string interpolation. Template Literals are a new ES2015 / ES6 feature that allows you to work with strings. The syntax is very simple, just use backticks instead of single or double quotes:

let a = `something                 something`;

and to make multiline strings just press enter to create a new line, with no special characters:

let a = `something 

    
                         something`;

The results are exactly the same as you write in the string.

Let's not forget math.hypot:

dist = math.hypot(x2-x1, y2-y1)

Here's hypot as part of a snippet to compute the length of a path defined by a list of (x, y) tuples:

from math import hypot

pts = [
    (10,10),
    (10,11),
    (20,11),
    (20,10),
    (10,10),
    ]

# Py2 syntax - no longer allowed in Py3
# ptdiff = lambda (p1,p2): (p1[0]-p2[0], p1[1]-p2[1])
ptdiff = lambda p1, p2: (p1[0]-p2[0], p1[1]-p2[1])

diffs = (ptdiff(p1, p2) for p1, p2 in zip (pts, pts[1:]))
path = sum(hypot(*d) for d in  diffs)
print(path)

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

What about anonymous fields? I'm not sure if that will constitute a "nested struct" but it's cleaner than having a nested struct declaration. What if you want to reuse the nested element elsewhere?

type NestedElement struct{
    someNumber int `json:"number"`
    someString string `json:"string"`
}

type BaseElement struct {
    NestedElement `json:"bar"`
}

That depends on what headers you are sending along with your CSS files. Check your server configuration as you are probably not sending them manually. Do a google search for "http caching" to learn about different caching options you can set. You can force the browser to download a fresh copy of the file everytime it loads it for instance, or you can cache the file for one week...

Using data.frame instead of cbind should be helpful

x <- data.frame(col1=c(10, 20), col2=c("[]", "[]"), col3=c("[[1,2]]","[[1,3]]"))
x
  col1 col2    col3
1   10   [] [[1,2]]
2   20   [] [[1,3]]

sapply(x, class) # looking into x to see the class of each element
     col1      col2      col3 
"numeric"  "factor"  "factor" 

As you can see elements from col1 are numeric as you wish.

data.frame can have variables of different class: numeric, factor and character but matrix doesn't, once you put a character element into a matrix all the other will become into this class no matter what clase they were before.

Use System.Collections.Generic.List

C# supports two boolean or operators: the single bar | and the double-bar ||.

The difference is that | always checks both the left and right conditions, while || only checks the right-side condition if it's necessary (if the left side evaluates to false).

This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close method took a while to complete or changed something's state.)

Here's a video that will show you, step-by-step, how to export data to Excel. It's a great solution for 'one-off' problems where you need to export to Excel:
Ad-Hoc Reporting

I have a simpler answer, which works perfectly for days; for months, it's +-2 days:

let today=new Date();
const days_to_subtract=30;
let new_date= new Date(today.valueOf()-(days_to_subtract*24*60*60*1000));

You get the idea - for months, multiply by 30; but that will be +-2 days.

To call ruby file use : ruby your_program.rb

To execute your ruby file as script:

1. start your program with #!/usr/bin/env ruby

2. run that script using ./your_program.rb param

3. If you are not able to execute this script check permissions for file.

The best option in my opinion is to compile a custom LESS file including bootstrap.less, a custom variables.less file and your own rules :

1. Clone bootstrap in your root folder : git clone https://github.com/twbs/bootstrap.git
2. Rename it "bootstrap"
3. Create a package.json file : https://gist.github.com/jide/8440609
4. Create a Gruntfile.js : https://gist.github.com/jide/8440502
5. Create a "less" folder
6. Copy bootstrap/less/variables.less into the "less" folder
7. Change the font path : @icon-font-path: "../bootstrap/fonts/";
8. Create a custom style.less file in the "less" folder which imports bootstrap.less and your custom variables.less file : https://gist.github.com/jide/8440619
9. Run npm install
10. Run grunt watch

Now you can modify the variables any way you want, override bootstrap rules in your custom style.less file, and if some day you want to update bootstrap, you can replace the whole bootstrap folder !

EDIT: I created a Bootstrap boilerplate using this technique : https://github.com/jide/bootstrap-boilerplate

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

You can use find option to select an element inside another. For example, to find an element with id txtName in a particular div, you can use like

var name = $('#div1').find('#txtName').val();

On SourceTree (GUI for GitHub), you may right-click the commit and do a 'Reverse Commit'. This should undo your changes.

On the terminal:

You may alternatively use:

git revert

Or:

git reset --soft HEAD^ # Use --soft if you want to keep your changes.
git reset --hard HEAD^ # Use --hard if you don't care about keeping your changes.

In this instance, your div elements have been changed from block level elements to inline elements. A typical characteristic of inline elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)

There are a few solutions that can be used to solve this.

Method 1 - Remove the whitespace from the markup

Example 1 - Comment the whitespace out: (example)

<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>

Example 2 - Remove the line breaks: (example)

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

Example 3 - Close part of the tag on the next line (example)

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

Example 4 - Close the entire tag on the next line: (example)

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

Method 2 - Reset the font-size

Since the whitespace between the inline elements is determined by the font-size, you could simply reset the font-size to 0, and thus remove the space between the elements.

Just set font-size: 0 on the parent elements, and then declare a new font-size for the children elements. This works, as demonstrated here (example)

#parent {
    font-size: 0;
}

#child {
    font-size: 16px;
}

This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size is declared using em units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline elements.

Method 3 - Set the parent element to display: flex

In some cases, you can also set the display of the parent element to flex. (example)

This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.

.parent {
    display: flex;
}
.parent > div {
    display: inline-block;
    padding: 1em;
    border: 2px solid #f00;
}

.parent {_x000D_
    display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
    display: inline-block;_x000D_
    padding: 1em;_x000D_
    border: 2px solid #f00;_x000D_
}

<div class="parent">_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
</div>

Sides notes:

It is incredibly unreliable to use negative margins to remove the space between inline elements. Please don't use negative margins if there are other, more optimal, solutions.

Suppose company C offers product P and P involves software in some way. Then C can offer a library/set of libraries to software developers that drive P's software systems.

That library/libraries are an SDK. It is part of the systems of P. It is a kit for software developers to use in order to modify, configure, fix, improve, etc the software piece of P.

If C wants to offer P's functionality to other companies/systems, it does so with an API.

This is an interface to P. A way for external systems to interact with P.

If you think in terms of implementation, they will seem quite similar. Especially now that the internet has become like one large distributed operating system.

In purpose, though, they are actually quite distinct.

You build something with an SDK and you use or consume something with an API.

FileInfo knows its own extension, so you could just remove it

fileInfo.Name.Replace(fileInfo.Extension, "");
fileInfo.FullName.Replace(fileInfo.Extension, "");

or if you're paranoid that it might appear in the middle, or want to microoptimize:

file.Name.Substring(0, file.Name.Length - file.Extension.Length)

All the above examples will actually REPLACE any params already present for the View, which may not be desired. The below code will just extend the existing params, without replacing them:

ImageView myImage = (ImageView) findViewById(R.id.image_view);
MarginLayoutParams marginParams = (MarginLayoutParams) image.getLayoutParams();
marginParams.setMargins(left, top, right, bottom);

axios.post can recieve accept 3 arguments that last argument can accept a config object that you can set header

Sample code with your question:

var data = {
'key1': 'val1',
'key2': 'val2'
}
axios.post(Helper.getUserAPI(), data, {
        headers: {Authorization: token && `Bearer ${ token }`}
})       
.then((response) => {
    dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
    dispatch({type: ERROR_FINDING_USER})
})

word of warning: the prefs:root or App-Prefs:root URL schemes are considered private API. Apple may reject you app if you use those, here is what you may get when submitting your app:

Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change. Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.

Next Steps

To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.

If there are no alternatives for providing the functionality your app requires, you can file an enhancement request.

It really helpful for the clickable part for some portion of the text.

The dot is a special character in the regular expression. If you want to spanable the dot need to escape dot as \\. instead of just passing "." to the spanable text method. Alternatively, you can also use the regular expression [.] to spanable the String by a dot in Java.

You don't have to do this locally either. You can do it through a remote repository, for example:

svn export http://<repo>/process/test.txt /path/to/code/

After finding answers around, I think this page might be helpful. https://www.typescriptlang.org/docs/handbook/declaration-merging.html#global-augmentation Not sure about the history of declaration merging, but it explains why the following could work.

declare global {
    interface Window { MyNamespace: any; }
}

window.MyNamespace = window.MyNamespace || {};

If you don't want to use dangerouslySetInnerHTML then you can use the below mentioned solution

var Iframe = React.createClass({     
  render: function() {
    return(         
      <div>          
        <iframe src={this.props.src} height={this.props.height} width={this.props.width}/>         
      </div>
    )
  }
});

ReactDOM.render(
  <Iframe src="http://plnkr.co/" height="500" width="500"/>,
  document.getElementById('example')
);

If you come to this thread because you're using the node postgres / pg module, there is a better solution than setting NODE_TLS_REJECT_UNAUTHORIZED or rejectUnauthorized, which will lead to insecure connections.

Instead, configure the "ssl" option to match the parameters for tls.connect:

{
  ca: fs.readFileSync('/path/to/server-ca.pem').toString(),
  cert: fs.readFileSync('/path/to/client-cert.pem').toString(),
  key: fs.readFileSync('/path/to/client-key.pem').toString(),
  servername: 'my-server-name' // e.g. my-project-id/my-sql-instance-id for Google SQL
}

I've written a module to help with parsing these options from environment variables like PGSSLROOTCERT, PGSSLCERT, and PGSSLKEY:

https://github.com/programmarchy/pg-ssl

var c = {'a':'A', 'b':'B', 'c':'C'};
var count = 0;
for (var i in c) {
   if (c.hasOwnProperty(i)) count++;
}

alert(count);

You can check phpinfo() (create a script containing and browse to it). This will tell you if you really do have it enabled. If not, read here.

It is not recommended for the faint-hearted Windows developer.

string.Format("{0:yyyy-MM-ddTHH:mm:ss.FFFZ}", DateTime.UtcNow)

For anyone else who stumbles across this thread but needs to find or create an object with attributes that might change depending on the circumstances, add the following method to your model:

# Return the first object which matches the attributes hash
# - or -
# Create new object with the given attributes
#
def self.find_or_create(attributes)
  Model.where(attributes).first || Model.create(attributes)
end

Optimization tip: regardless of which solution you choose, consider adding indexes for the attributes you are querying most frequently.

curl -v --trace-time This must be done in verbose mode

Actually, there's an easier (built in) way of doing this:

instead of modifying adb_usb.ini file I made changes on the file android_winusb.inf under directory android-sdk\extras\google\usb_driver\ alone and it worked for the tablet MID Q88 but i copied both sections [Google.NTamd64] and [Google.NTx86]

;Google MID Q88
%SingleAdbInterface%        = USB_INSTALL, USB\VID_18D1&PID_0003&MI_01
%CompositeAdbInterface%     = USB_INSTALL, USB\VID_18D1&PID_0003&REV_0230&MI_01

Try setting core.autocrlf value like this :

git config --global core.autocrlf true

It depends on the product. A product could be implemented that (under the covers) converts all UPDATEs into a (transactionally wrapped) DELETE and INSERT. Provided the results are consistent with the UPDATE semantics.

I'm not saying I'm aware of any product that does this, but it's perfectly legal.

Try the following code:

moment(startDate).startOf('months')
moment(startDate).endOf('months')

We can use case statement Like this

select Name,EmailId,gender=case 
when gender='M' then 'F'
when gender='F' then 'M'
end
 from [dbo].[Employees]

WE can also it as follow.

select Name,EmailId,case gender
when 'M' then 'F'
when 'F' then 'M'
end
 from [dbo].[Employees]

*.so library in Android Studio

You have to generate jniLibs folder inside main in android Studio projects and put your all .so files inside. You can also integrate this line in build.gradle

compile fileTree(dir: 'libs', include: ['.jar','.so'])

It's work perfectly

|--app:

|--|--src:

|--|--|--main

|--|--|--|--jniLibs

|--|--|--|--|--armeabi

|--|--|--|--|--|--.so Files

This is the project structure.

Using regular expressions, you can represent any whitespace character with the metacharacter "\s"

MSDN Reference

The return type of Html.RenderAction is void that means it directly renders the responses in View where the return type of Html.Action is MvcHtmlString You can catch its render view in controller and modify it by using following method

protected string RenderPartialViewToString(string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = ControllerContext.RouteData.GetRequiredString("action");

        ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            return sw.GetStringBuilder().ToString();
        }
    }

This will return the Html string of the View.

This is also applicable to Html.Partial and Html.RenderPartial

If your using PHP and MySQL you can use the mysql_insert_id() function which will tell you the ID of item you Just instered.
But without your Language and DBMS I'm just shooting in the dark here.

You want to do the following:

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS 
BEGIN
SET NOCOUNT ON;

    IF (UPDATE(QtyToRepair))
    BEGIN
        UPDATE SCHEDULE SET modified = GETDATE()
            , ModifiedUser = SUSER_NAME()
            , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S
        INNER JOIN Inserted I ON S.OrderNo = I.OrderNo AND S.PartNumber = I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END
END

Please note that this trigger will fire each time you update the column no matter if the value is the same or not.

Not taking anything away from Nikos' awesome answer, perhaps you can do this more simply:

<form name="telForm">
  <input name="cb" type='checkbox' data-ng-modal='requireTel'>
  <input name="tel" type="text" ng-model="..." ng-if='requireTel' ng-pattern="phoneNumberPattern" required/>
  <button type="submit" ng-disabled="telForm.$invalid || telForm.$pristine">Submit</button>
</form>

Pay attention to the second input: We can use an ng-if to control rendering and validation in forms. If the requireTel variable is unset, the second input would not only be hidden, but not rendered at all, thus the form will pass validation and the button will become enabled, and you'll get what you need.

For anyone who is wanting to sort by date (UK format), I used the following:

//Sort by day, then month, then year
for(i=0;i<=2; i++){
    dataCourses.sort(function(a, b){

        a = a.lastAccessed.split("/");
        b = b.lastAccessed.split("/");

        return a[i]>b[i] ? -1 : a[i]<b[i] ? 1 : 0;
    }); 
}

By default, the update() method updates a single document. Set the Multi Parameter to update all documents that match the query criteria.

Changed in version 3.6. Syntax :

db.collection.update(
   <query>,
   <update>,
   {
     upsert: <boolean>,
     multi: <boolean>,
     writeConcern: <document>,
     collation: <document>,
     arrayFilters: [ <filterdocument1>, ... ]
   }
)

Example :

db.getCollection('products').update({},{$unset: {translate:1, qordoba_translation_version:1}}, {multi: true})

In your example :

db.getCollection('products').update({},{$unset: {'tags.words' :1}},  {multi: true})

The other posters are correct you cannot connect to MySQL directly from javascript. This is because JavaScript is at client side & mysql is server side.

So your best bet is to use ajax to call a handler as quoted above if you can let us know what language your project is in we can better help you ie php/java/.net

If you project is using php then the example from Merlyn is a good place to start, I would personally use jquery.ajax() to cut down you code and have a better chance of less cross browser issues.

simple way to do 'groupby' and sorting in descending order

Be aware that Total Server Memory is NOT how much memory SQL Server is currently using.

refer to this Microsoft article: http://msdn.microsoft.com/en-us/library/ms190924.aspx

Simply create a .bat file with the following lines in it:

@ECHO OFF
set CLASSPATH=.
set CLASSPATH=%CLASSPATH%;path/to/needed/jars/my.jar

%JAVA_HOME%\bin\java -Xms128m -Xmx384m -Xnoclassgc ro.my.class.MyClass

Most objects don't have a __name__ attribute. (Classes, functions, and modules do; any more builtin types that have one?)

What else would you expect for print(my_var.__name__) other than print("my_var")? Can you simply use the string directly?

You could "slice" a dict:

def dict_slice(D, keys, default=None):
  return dict((k, D.get(k, default)) for k in keys)

print dict_slice(locals(), ["foo", "bar"])
# or use set literal syntax if you have a recent enough version:
print dict_slice(locals(), {"foo", "bar"})

Alternatively:

throw = object()  # sentinel
def dict_slice(D, keys, default=throw):
  def get(k):
    v = D.get(k, throw)
    if v is not throw:
      return v
    if default is throw:
      raise KeyError(k)
    return default
  return dict((k, get(k)) for k in keys)

You don't need align="center" and float:left. Remove both of these. margin: 0 auto is sufficient.

For adding a RelativeLayout attribute whose value is true or false use 0 for false and RelativeLayout.TRUE for true:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) button.getLayoutParams()
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE)

It doesn't matter whether or not the attribute was already added, you still use addRule(verb, subject) to enable/disable it. However, post-API 17 you can use removeRule(verb) which is just a shortcut for addRule(verb, 0).

(This is the KISS answer.)

Let's say you have several .java files in the current directory:

$ ls -1 *.java
javaFileName1.java
javaFileName2.java

Let's say each of them have a main() method (so they are programs, not libs), then to compile them do:

javac *.java -d .

This will generate as many subfolders as "packages" the .java files are associated to. In my case all java files where inside under the same package name packageName, so only one folder was generated with that name, so to execute each of them:

java -cp . packageName.javaFileName1
java -cp . packageName.javaFileName2

The beauty of reactive forms is you can catch values changes event of any input element very easily and at the same time you can change their values/ status. So here is the another way to tackle your problem by using enable disable.

Here is the complete solution on stackblitz.

If you want to take a copy of a live database, do the Backup/Restore method.

[In SQLS2000, not sure about 2008:] Just keep in mind that if you are using SQL Server accounts in this database, as opposed to Windows accounts, if the master DB is different or out of sync on the development server, the user accounts will not translate when you do the restore. I've heard about an SP to remap them, but I can't remember which one it was.

To delete all records from a table without deleting the table.

DELETE FROM table_name use with care, there is no undo!

To remove a table

DROP TABLE table_name

The problem with the original code is that:

• h: expects parameter where it shouldn't, so change it into just h (without colon)
• to expect -p any_string, you need to add p: to the argument list

Basically : after the option means it requires the argument.

The basic syntax of getopts is (see: man bash):

getopts OPTSTRING VARNAME [ARGS...]

where:

• OPTSTRING is string with list of expected arguments,

  • h - check for option -h without parameters; gives error on unsupported options;
  • h: - check for option -h with parameter; gives errors on unsupported options;
  • abc - check for options -a, -b, -c; gives errors on unsupported options;

  • :abc - check for options -a, -b, -c; silences errors on unsupported options;

    ^{Notes: In other words, colon in front of options allows you handle the errors in your code. Variable will contain ? in the case of unsupported option, : in the case of missing value.}

• OPTARG - is set to current argument value,

• OPTERR - indicates if Bash should display error messages.

So the code can be:

#!/usr/bin/env bash
usage() { echo "$0 usage:" && grep " .)\ #" $0; exit 0; }
[ $# -eq 0 ] && usage
while getopts ":hs:p:" arg; do
  case $arg in
    p) # Specify p value.
      echo "p is ${OPTARG}"
      ;;
    s) # Specify strength, either 45 or 90.
      strength=${OPTARG}
      [ $strength -eq 45 -o $strength -eq 90 ] \
        && echo "Strength is $strength." \
        || echo "Strength needs to be either 45 or 90, $strength found instead."
      ;;
    h | *) # Display help.
      usage
      exit 0
      ;;
  esac
done

Example usage:

$ ./foo.sh 
./foo.sh usage:
    p) # Specify p value.
    s) # Specify strength, either 45 or 90.
    h | *) # Display help.
$ ./foo.sh -s 123 -p any_string
Strength needs to be either 45 or 90, 123 found instead.
p is any_string
$ ./foo.sh -s 90 -p any_string
Strength is 90.
p is any_string

Ctrl+] - go to definition
Ctrl+T - Jump back from the definition.
Ctrl+W Ctrl+] - Open the definition in a horizontal split

Add these lines in vimrc
map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>

Ctrl+\ - Open the definition in a new tab
Alt+] - Open the definition in a vertical split

After the tags are generated. You can use the following keys to tag into and tag out of functions:

Ctrl+Left MouseClick - Go to definition
Ctrl+Right MouseClick - Jump back from definition

I think the problem is given in the error message, although it is not very easy to spot:

IndexError: too many indices for array
xs  = data[:, col["l1"     ]]

'Too many indices' means you've given too many index values. You've given 2 values as you're expecting data to be a 2D array. Numpy is complaining because data is not 2D (it's either 1D or None).

This is a bit of a guess - I wonder if one of the filenames you pass to loadfile() points to an empty file, or a badly formatted one? If so, you might get an array returned that is either 1D, or even empty (np.array(None) does not throw an Error, so you would never know...). If you want to guard against this failure, you can insert some error checking into your loadfile function.

I highly recommend in your for loop inserting:

print(data)

This will work in Python 2.x or 3.x and might reveal the source of the issue. You might well find it is only one value of your outputs_l1 list (i.e. one file) that is giving the issue.

IIFE (Immediately invoked function expression) is a function which executes as soon as the script loads and goes away.

Consider the function below written in a file named iife.js

(function(){
       console.log("Hello Stackoverflow!");
   })();

This code above will execute as soon as you load iife.js and will print 'Hello Stackoverflow!' on the developer tools' console.

For a Detailed explanation see Immediately-Invoked Function Expression (IIFE)

Just to reload everything , use window.location.reload(); with angularjs

Check out working example

HTML

<div ng-controller="MyCtrl">  
<button  ng-click="reloadPage();">Reset</button>
</div>

angularJS

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    $scope.reloadPage = function(){window.location.reload();}
}

find . -type f | 
sed -n "s/\(.*\)factory\.py$/& \1service\.py/p" | 
xargs -p -n 2 mv

eg will rename all files in the cwd with names ending in "factory.py" to be replaced with names ending in "service.py"

explanation:

1) in the sed cmd, the -n flag will suppress normal behavior of echoing input to output after the s/// command is applied, and the p option on s/// will force writing to output if a substitution is made. since a sub will only be made on match, sed will only have output for files ending in "factory.py"

2) in the s/// replacement string, we use "& " to interpolate the entire matching string, followed by a space character, into the replacement. because of this, it's vital that our RE matches the entire filename. after the space char, we use "\1service.py" to interpolate the string we gulped before "factory.py", followed by "service.py", replacing it. So for more complex transformations youll have to change the args to s/// (with an re still matching the entire filename)

example output:

foo_factory.py foo_service.py
bar_factory.py bar_service.py

3) we use xargs with -n 2 to consume the output of sed 2 delimited strings at a time, passing these to mv (i also put the -p option in there so you can feel safe when running this). voila.

... Thanks guys... all I needed was the 'value' of the checked radio button where each radio button in the set had a different id...

 var user_cat = $("input[name='user_cat']:checked").val();

works for me...

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' || r.serial# || '''';
  END LOOP;
END;
/

It works for me.

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:

insert into errortable (dateupdated, table1id)
    values (sysdate, 1083);

It seems silly to convert the system date to a string just to convert it back to a date.

If you want to see the full date, then you can do:

select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;

You need to add quotes. VBA is translating

Rows(copyToRow & ":" & copyToRow).Select`

into

 Rows(52:52).Select

Try changing

Rows(""" & copyToRow & ":" & copyToRow & """).Select

The jar file is just an executable java program. If you want to modify the code, you have to open the .java files.

For a bordered and scrollable table, use this (replace variables, $ starting texts)

If you use thead, tfoot or th, just replace tr:first-child and tr-last-child and td with them.

#table-wrap {
  border: $border solid $color-border;
  border-radius: $border-radius;
}
table {
  border-collapse: collapse;
  border-spacing: 0;
}
table td { border: $border solid $color-border; }
table td:first-child { border-left: none; }
table td:last-child { border-right: none; }
table tr:first-child td { border-top: none; }
table tr:last-child td { border-bottom: none; }
table tr:first-child td:first-child { border-top-left-radius: $border-radius; }
table tr:first-child td:last-child { border-top-right-radius: $border-radius; }
table tr:last-child td:first-child { border-bottom-left-radius: $border-radius; }
table tr:last-child td:last-child { border-bottom-right-radius: $border-radius; }

HTML:

<div id=table-wrap>
  <table>
    <tr>
       <td>1</td>
       <td>2</td>
    </tr>
    <tr>
       <td>3</td>
       <td>4</td>
    </tr>
  </table>
</div>

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

Short and simple:

Function.prototype.clone = function() {
  return new Function('return ' + this.toString())();
};

Check out the CharsetEncoder and CharsetDecoder API descriptions - You should follow a specific sequence of method calls to avoid this problem. For example, for CharsetEncoder:

1. Reset the encoder via the reset method, unless it has not been used before;
2. Invoke the encode method zero or more times, as long as additional input may be available, passing false for the endOfInput argument and filling the input buffer and flushing the output buffer between invocations;
3. Invoke the encode method one final time, passing true for the endOfInput argument; and then
4. Invoke the flush method so that the encoder can flush any internal state to the output buffer.

By the way, this is the same approach I am using for NIO although some of my colleagues are converting each char directly to a byte in the knowledge they are only using ASCII, which I can imagine is probably faster.

If you have them already in a byte[] array, you can use:

int result = ByteBuffer.wrap(bytes).getInt();

source: here

I may be missing part of the question, but I believe you can simply do this:

$('.testimonial').each((index, element) => {
    if (/* Condition */) {
        // Do Something
    }
});

This uses jQuery's each method: https://learn.jquery.com/using-jquery-core/iterating/

You can use the DataRowView to get the column index.

    void OnRequestsGridRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            var data = e.Row.DataItem as DataRowView;

            // replace request name with a link
            if (data.DataView.Table.Columns["Request Name"] != null)
            {
                // get the request name
                string title = data["Request Name"].ToString();
                // get the column index
                int idx = data.Row.Table.Columns["Request Name"].Ordinal;

                // ...

                e.Row.Cells[idx].Controls.Clear();
                e.Row.Cells[idx].Controls.Add(link);
            }
        }
    }

With Yglu Structural Templating, your example can be written:

foo: !()
  !? $.propname: 
     type: number 
     default: !? $.default

bar:
  !apply .foo: 
    propname: "some_prop"
    default: "some default"

With flexbox this is easy:

FIDDLE

Just add the following to the image container:

.img-container {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    display: flex; /* add */
    justify-content: center; /* add to align horizontal */
    align-items: center; /* add to align vertical */
}

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

$dbh = new PDO('pgsql:host=localhost;port=5432;dbname=###;user=###;password=##');

For PDO type connection uncomment

extension=php_pdo_pgsql.dll and comment with

;extension=php_pgsql.dll

$dbh = pg_connect("host=localhost dbname=### user=### password=####");

For pgconnect type connection comment

;extension=php_pdo_pgsql.dll and uncomment

extension=php_pgsql.dll

Both the connections should work.

That's because in C - integer on 32 bit machine doesn't mean that 32 bits are used for storing it, it may be 16 bits as well. It depends on the machine (implementation-dependent).

http://docs.jquery.com/Events/jQuery.Event

Try with event.target

Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.

This sounds like you're using numpy.

If that's the case, you can add:

import numpy as np
np.set_printoptions(threshold=np.nan)

That will disable the corner printing. For more information, see this NumPy Tutorial.

Padding is the space inside the border between the border and the actual image or cell contents. Margins are the spaces outside the border, between the border and the other elements next to this object.

margin-top:0;
margin-bottom:0;
margin-left:auto;
margin-right:auto;

0 is for top-bottom and auto for left-right. The browser sets the margin.

Composition API

Template refs section tells how this has been unified:

• within template, use ref="myEl"; :ref= with a v-for
• within script, have a const myEl = ref(null) and expose it from setup

The reference carries the DOM element from mounting onwards.

EXPOSURE OF API KEYS ISN'T A SECURITY RISK BUT ANYONE CAN PUT YOUR CREDENTIALS ON THEIR SITE.

Open api keys leads to attacks that can use a lot resources at firebase that will definitely cost your hard money.

You can always restrict you firebase project keys to domains / IP's.

select your project Id and key and restrict it to Your Android/iOs/web App.

Solution for Android Studio 3.6:

yourSwitch.setTextColor(getResources().getColor(R.color.yourColor));

Changes the text color of a in the color XML file defined value (yourColor).

With ECMAScript 2015 you can export and import multiple classes like this

class Person
{
    constructor()
    {
        this.type = "Person";
    }
}

class Animal{
    constructor()
    {
        this.type = "Animal";
    }
}

module.exports = {
    Person,
    Animal
};

then where you use them:

const { Animal, Person } = require("classes");

const animal = new Animal();
const person = new Person();

In case of name collisions, or you prefer other names you can rename them like this:

const { Animal : OtherAnimal, Person : OtherPerson} = require("./classes");

const animal = new OtherAnimal();
const person = new OtherPerson();

It is a static function on the MessageBox class, the simple way to do this is using

MessageBox.Show("my message");

in the System.Windows.Forms class. You can find more on the msdn page for this here . Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message"); or confirm("my question"); functions.

        double dlat = (latitude - e) * d2r;
        double a = Math.pow(Math.sin(dlat / 2.0), 2) + Math.cos(e * d2r)

The following (C#) code should do the trick

Uri uri = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
string requested = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;

In my case, the culprit was not distinguish the main and test sources folder within pom.xml (generated by eclipse maven project)

<build>
    <sourceDirectory>src</sourceDirectory>
    ....
</build>

If you override default source folder settings in pom file, you must explicitly set the main AND test source folders!!!!

<build>
    <sourceDirectory>src/main/java</sourceDirectory>
    <testSourceDirectory>src/test/java</testSourceDirectory>
    ....
</build>
