You can take advantage of Groovy features like with(), improvements to URLConnection, and simplified getters/setters:

GET:

String getResult = new URL('http://mytestsite/bloop').text

POST:

String postResult
((HttpURLConnection)new URL('http://mytestsite/bloop').openConnection()).with({
    requestMethod = 'POST'
    doOutput = true
    setRequestProperty('Content-Type', '...') // Set your content type.
    outputStream.withPrintWriter({printWriter ->
        printWriter.write('...') // Your post data. Could also use withWriter() if you don't want to write a String.
    })
    // Can check 'responseCode' here if you like.
    postResult = inputStream.text // Using 'inputStream.text' because 'content' will throw an exception when empty.
})

Note, the POST will start when you try to read a value from the HttpURLConnection, such as responseCode, inputStream.text, or getHeaderField('...').

You need to aggregate the data first, this can be done using the GROUP BY clause:

SELECT Group, COUNT(*)
FROM table
GROUP BY Group
ORDER BY COUNT(*) DESC

The DESC keyword allows you to show the highest count first, ORDER BY by default orders in ascending order which would show the lowest count first.

This is the best way (IMHO).

List<String> myArrayList = new ArrayList<String>();
//.....
String[] myArray = myArrayList.toArray(new String[myArrayList.size()]);

This code works also:

String[] myArray = myArrayList.toArray(new String[0]);

But it less effective: the string array is created twice: first time zero-length array is created, then the real-size array is created, filled and returned. So, if since you know the needed size (from list.size()) you should create array that is big enough to put all elements. In this case it is not re-allocated.

var cts = new CancellationTokenSource();
var task = Task.Run(() => { while (true) { } });
Parallel.Invoke(() =>
{
    task.Wait(cts.Token);
}, () =>
{
    Thread.Sleep(1000);

});

This is a simple snippet to abort a never-ending task with CancellationTokenSource.

:last is not part of the css spec, this is jQuery specific.

you should be looking for last-child

var first = div.querySelector('[move_id]:first-child');
var last  = div.querySelector('[move_id]:last-child');

When you have image into yours drawable gallery then you just need to pick the option of image view pick and drag into app activity you want to show and select the required image.

Why use normal jquery ajax feature. Why not use jquery ajax form plugin, which post the form data by ajax to the form action link.

Check it here:

http://malsup.com/jquery/form/#getting-started

It is very easy to use and support several data formats including json, html xml etc. Checkout the example and you will find it very easy to use.

Thank you

Use the Application.DispatcherUnhandledException Event. See this question for a summary (see Drew Noakes' answer).

Be aware that there'll be still exceptions which preclude a successful resuming of your application, like after a stack overflow, exhausted memory, or lost network connectivity while you're trying to save to the database.

I don't know about the runtime disadvantages about the following but you could run a regexp match on your string to make sure it is a number before trying to parse it, thus

cost.matches("-?\\d+\\.?\\d+")

for a float

and

cost.matches("-?\\d+")

for an integer

EDIT

please notices @Voo's comment about max int

Use dbms_lob.instr and dbms_lob.substr, just like regular InStr and SubstStr functions.
Look at simple example:

It's not January 1, 1753 but select cast('' as datetime) wich reveals: 1900-01-01 00:00:00.000 gives the default value by SQL server. (Looks more uninitialized to me anyway)

If you are using nodejs, in your package.json under scripts

1. For global (-g) installations: "test": "mocha server-test" or "test": "mocha server-test/**/*.js" for subdocuments
2. For project installations: "test": "node_modules/mocha/bin/mocha server-test" or "test": "node_modules/mocha/bin/mocha server-test/**/*.js" for subdocuments

Then just run your tests normally as npm test

Error messages usually mean precisely what they say. So they must be read very carefully. When you do that, you'll see that this one is not actually complaining, as you seem to have assumed, about what sort of object your list contains, but rather about what sort of object it is. It's not saying it wants your list to contain integers (plural)—instead, it seems to want your list to be an integer (singular) rather than a list of anything. And since you can't convert a list into a single integer (at least, not in a way that is meaningful in this context) you shouldn't be trying.

So the question is: why does the interpreter seem to want to interpret your list as an integer? The answer is that you are passing your list as the input argument to range, which expects an integer. Don't do that. Say for i in myList instead.

Well there's always

assertThat(list.isEmpty(), is(false));

... but I'm guessing that's not quite what you meant :)

Alternatively:

assertThat((Collection)list, is(not(empty())));

empty() is a static in the Matchers class. Note the need to cast the list to Collection, thanks to Hamcrest 1.2's wonky generics.

The following imports can be used with hamcrest 1.3

import static org.hamcrest.Matchers.empty;
import static org.hamcrest.core.Is.is;
import static org.hamcrest.core.IsNot.*;

There are three ways to enlarge the max_allowed_packet of mysql server:

1. Change max_allowed_packet=64M in file /etc/mysql/my.cnf on the mysql server machine and restart the server
2. Execute the sql on the mysql server: set global max_allowed_packet=67108864;
3. Python executes sql after connecting to the mysql:

connection.execute('set max_allowed_packet=67108864')

you use the scrollTop attribute

var position = document.getElementById('id').scrollTop;

More simple than that.

List<Integer> arrayIntegers = new ArrayList<>(Arrays.asList(1,2,3));

arrayIntegers.get(1);

In the first line you create the object and in the constructor you pass an array parameter to List.

In the second line you have all the methods of the List class: .get (...)

If anyone is still looking for an easy way to decompile an APK (with resource decompiling), have a look at the tools I have created: https://github.com/dirkvranckaert/AndroidDecompiler

Just checkout the project locally and run the script as documented and you'll get all the resources and sources decompiled.

Sure, you can use JS's foreach.

for (var k in result) {
  something(result[k])
}

@Travis solution is right, but it loses milliseconds when a Date is generated. I have added a line to include the milliseconds into the date:

If you don't need this precision, use the Travis solution because it will be faster.

extension Date {

    func toMillis() -> Int64! {
        return Int64(self.timeIntervalSince1970 * 1000)
    }

    init(millis: Int64) {
        self = Date(timeIntervalSince1970: TimeInterval(millis / 1000))
        self.addTimeInterval(TimeInterval(Double(millis % 1000) / 1000 ))
    }

}

Understand that .children is a property of an Element. ¹ Only Elements have .children, and these children are all of type Element. ²

However, .childNodes is a property of Node. .childNodes can contain any node. ³

A concrete example would be:

let el = document.createElement("div");
el.textContent = "foo";

el.childNodes.length === 1; // Contains a Text node child.
el.children.length === 0;   // No Element children.

Most of the time, you want to use .children because generally you don't want to loop over Text or Comment nodes in your DOM manipulation.

If you do want to manipulate Text nodes, you probably want .textContent instead. ⁴

<sup>1. Technically, it is an attribute of ParentNode, a mixin included by Element.
2. They are all elements because .children is a HTMLCollection, which can only contain elements.
3. Similarly, .childNodes can hold any node because it is a NodeList.
4. Or .innerText. See the differences here or here.</sup>

A slight adaptation to the solution above by kingjeffrey for when you want to create and echo the CSV within a template (Ie - most frameworks will have output buffering enabled and you are required to set headers etc in controllers.)

// Create Some data
<?php
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );


// Create a stream opening it with read / write mode
$stream = fopen('data://text/plain,' . "", 'w+');

// Iterate over the data, writting each line to the text stream
foreach ($data as $val) {
    fputcsv($stream, $val);
}

// Rewind the stream
rewind($stream);

// You can now echo it's content
echo stream_get_contents($stream);

// Close the stream 
fclose($stream);

Credit to Kingjeffrey above and also to this blog post where I found the information about creating text streams.

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

It's a mechanism to invoke an API in an asynchrounous way. The sequence is the following

1. your app invokes the url, passing as parameter the callback url
2. the api respond with a 20x http code (201 I guess, but refer to the api docs)
3. the api works on your request for a certain amount of time
4. the api invokes your app to give you the results, at the callback url address.

So you can invoke the api and tell your user the request is "processing" or "acquired" for example, and then update the status when you receive the response from the api.

Hope it makes sense. -G

If you want to just delay the closing of the window without having to actually press a button (getchar() method), you can simply use the sleep() method; it takes the amount of seconds you want to sleep as an argument.

#include <unistd.h>
// your code here
sleep(3); // sleep for 3 seconds

References: sleep() manual

I don't think it is possible. You can reuse "node" but not part of it.

bill-to: &id001
    given  : Chris
    family : Dumars
ship-to: *id001

This is perfectly valid YAML and fields given and family are reused in ship-to block. You can reuse a scalar node the same way but there's no way you can change what's inside and add that last part of a path to it from inside YAML.

If repetition bother you that much I suggest to make your application aware of root property and add it to every path that looks relative not absolute.

If you do the call several times you can use the new method handles introduced in Java 7. Here we go for your method returning a String:

Object obj = new Point( 100, 200 );
String methodName = "toString";  
Class<String> resultType = String.class;

MethodType mt = MethodType.methodType( resultType );
MethodHandle methodHandle = MethodHandles.lookup().findVirtual( obj.getClass(), methodName, mt );
String result = resultType.cast( methodHandle.invoke( obj ) );

System.out.println( result );  // java.awt.Point[x=100,y=200]

You would do something like that using Google API.

Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.

"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.

Anyhow - more details on google response types can be found here and here.

I am training with a angular2 tutorial(hero).
After installing @types/core-js commented in theses answers, I got a "Duplicate identifier" error.
In my case, it was solved as removing lib line in tsconfig.json.

//"lib": [ "es2015", "dom" ]

Here's the solution. Your code will like this:

button.setOnClickListener {
            //your code here
        }

No need to add anything. like below:

val button = findViewById<Button>(R.id.Button)
button.setOnClickListener {

}

You can add border to the UIImageView, and then change the size of the UIimageView according to the image size:

#import <QuartzCore/QuartzCore.h>


// adding border to the imageView
[imageView.layer setBorderColor: [[UIColor whiteColor] CGColor]];
[imageView.layer setBorderWidth: 2.0];

// resize the imageView to fit the image size
CGSize size = [image size];
float factor = size.width / self.frame.size.width;
if (factor < size.height / self.frame.size.height) {
    factor = size.height / self.frame.size.height;
}

CGRect rect = CGRectMake(0, 0, size.width/factor, size.height/factor);
imageView.frame = rect;

Make sure you to set the origin of the imageView to the center

I got this problem first: PM> add-migration first

No migrations configuration type was found in the assembly 'MyProjectName'. (In Visual Studio you can use the Enable-Migrations command from Package Manager Console to add a migrations configuration).

then i tried this:

PM> Enable-Migrations No context type was found in the assembly 'MyProjectName'.

Then the right command for me :

PM> Enable-Migrations -ProjectName MyProjectName -ContextTypeName MyProjectName.Data.Context

After that i got this error message even though Context inherits from DbContext

The type 'Context' does not inherit from DbContext. The DbMigrationsConfiguration.ContextType property must be set to a type that inherits from DbContext.

Then i Installed Microsoft.EntityFrameworkCore.Tools

ITS OK NOW but the message is funny. i already tried add migrations at first :D

Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework6\Enable-Migrations' for Entity Framework 6. Enable-Migrations is obsolete. Use Add-Migration to start using Migrations.

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

From the GNU UPC website:

Compiler build fails with fatal error: gnu/stubs-32.h: No such file or directory

This error message shows up on the 64 bit systems where GCC/UPC multilib feature is enabled, and it indicates that 32 bit version of libc is not installed. There are two ways to correct this problem:

• Install 32 bit version of glibc (e.g. glibc-devel.i686 on Fedora, CentOS, ..)
• Disable 'multilib' build by supplying "--disable-multilib" switch on the compiler configuration command

As option, if you need just default text in dropdown without default value, try add <option disabled value="null">default text here</option> like this:

<select id="country" formControlName="country">
 <option disabled value="null">default text here</option>
 <option *ngFor="let c of countries" [value]="c" >{{ c }}</option>
</select>

In Chrome and Firefox works fine.

I suggest loganfsmyths method, using an array to hold the data.

var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
  var buf = Buffer.concat(bufs);
}

IN my current working example, i am working with GRIDfs and npm's Jimp.

   var bucket = new GridFSBucket(getDBReference(), { bucketName: 'images' } );
    var dwnldStream = bucket.openDownloadStream(info[0]._id);// original size
  dwnldStream.on('data', function(chunk) {
       data.push(chunk);
    });
  dwnldStream.on('end', function() {
    var buff =Buffer.concat(data);
    console.log("buffer: ", buff);
       jimp.read(buff)
.then(image => {
         console.log("read the image!");
         IMAGE_SIZES.forEach( (size)=>{
         resize(image,size);
         });
});

I did some other research

with a string method but that did not work, per haps because i was reading from an image file, but the array method did work.

const DISCLAIMER = "DONT DO THIS";
var data = "";
stdout.on('data', function(d){ 
           bufs+=d; 
         });
stdout.on('end', function(){
          var buf = Buffer.from(bufs);
          //// do work with the buffer here

          });

When i did the string method i got this error from npm jimp

buffer:  <Buffer 00 00 00 00 00>
{ Error: Could not find MIME for Buffer <null>

basically i think the type coersion from binary to string didnt work so well.

It affects the whole child divs when you use the opacity feature with positions other than absolute. So another way to achieve it not to put divs inside each other and then use the position absolute for the divs. Dont use any background color for the upper div.

I had the same problem using GitLab, and here's how i fixed it:

1. Generate an access token: to do so go to settings/access tokens, then give it a name and expiration date and submit.

2. In your project files open the "config" file in ".git" directory: /.git/config.

3. You will find a line like this:

   [remote "origin"] url = https://[username]:[token]@your-domain.com/your-project.git

4. You will have your gitlab username instead of [username], and you should replace [token] with your token generated in step 1.

5. Save the changes.

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

You can certainly do something like

However, if you find yourself using nested cursor FOR loops, it is almost always more efficient to let the database join the two results for you. After all, relational databases are really, really good at joining. I'm guessing here at what your tables look like and how they relate based on the code you posted but something along the lines of

FOR x IN (SELECT *
            FROM all_users,
                 org
           WHERE length(all_users.username) = 3
             AND all_users.username = org.username )
LOOP
  <<do something>>
END LOOP;

Your stored procedures work as coded. The problem is with the last line, it is unable to invoke either of your stored procedures.

Three choices in SQL*Plus are: call, exec, and an anoymous PL/SQL block.

call appears to be a SQL keyword, and is documented in the SQL Reference. http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG The syntax diagram indicates that parentesis are required, even when no arguments are passed to the call routine.

CALL test_sp_1();

An anonymous PL/SQL block is PL/SQL that is not inside a named procedure, function, trigger, etc. It can be used to call your procedure.

BEGIN
    test_sp_1;
END;
/

Exec is a SQL*Plus command that is a shortcut for the above anonymous block. EXEC <procedure_name> will be passed to the DB server as BEGIN <procedure_name>; END;

Full example:

SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE test_sp

Some time ago Jupyter Notebooks started stripping JavaScript from HTML content [#3118]. Here are two solutions:

Serving Local HTML

If you want to embed an HTML page with JavaScript on your page now, the easiest thing to do is to save your HTML file to the directory with your notebook and then load the HTML as follows:

from IPython.display import IFrame

IFrame(src='./nice.html', width=700, height=600)

Serving Remote HTML

If you prefer a hosted solution, you can upload your HTML page to an Amazon Web Services "bucket" in S3, change the settings on that bucket so as to make the bucket host a static website, then use an Iframe component in your notebook:

from IPython.display import IFrame

IFrame(src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600)

This will render your HTML content and JavaScript in an iframe, just like you can on any other web page:

<iframe src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600></iframe>

The neatest command is

grep -vc ^$ fileName

with -c option, you don't even need wc -l

Just in case, here is what I did to get partial arguments, kind of. I’ve created a little helper that takes a partial name and a hash of parameters that will be passed to the partial:

Handlebars.registerHelper('render', function(partialId, options) {
  var selector = 'script[type="text/x-handlebars-template"]#' + partialId,
      source = $(selector).html(),
      html = Handlebars.compile(source)(options.hash);

  return new Handlebars.SafeString(html);
});

The key thing here is that Handlebars helpers accept a Ruby-like hash of arguments. In the helper code they come as part of the function’s last argument—options— in its hash member. This way you can receive the first argument—the partial name—and get the data after that.

Then, you probably want to return a Handlebars.SafeString from the helper or use “triple-stash”—{{{— to prevent it from double escaping.

Here is a more or less complete usage scenario:

<script id="text-field" type="text/x-handlebars-template">
  <label for="{{id}}">{{label}}</label>
  <input type="text" id="{{id}}"/>
</script>

<script id="checkbox-field" type="text/x-handlebars-template">
  <label for="{{id}}">{{label}}</label>
  <input type="checkbox" id="{{id}}"/>
</script>

<script id="form-template" type="text/x-handlebars-template">
  <form>
    <h1>{{title}}</h1>
    {{ render 'text-field' label="First name" id="author-first-name" }}
    {{ render 'text-field' label="Last name" id="author-last-name" }}
    {{ render 'text-field' label="Email" id="author-email" }}
    {{ render 'checkbox-field' label="Private?" id="private-question" }}
  </form>
</script>

Hope this helps …someone. :)

Here's a solution I've used, similiar to Ansgar Wiechers' solution;

$title = "Lorem"
$message = "Ipsum"

$yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes", "This means Yes"
$no = New-Object System.Management.Automation.Host.ChoiceDescription "&No", "This means No"

$options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $no)

$result = $host.ui.PromptForChoice($title, $message, $Options, 0)

Switch ($result)
     {
          0 { "You just said Yes" }
          1 { "You just said No" }
     }

You can use the stat command

stat -c %y "$entry"

More info

%y   time of last modification, human-readable

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
    string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with foreach or for any GridView event like OnRowDataBound.

Here you can input multiple values for DataKeyNames by separating with comma ,. For example, DataKeyNames="ProductID,ItemID,OrderID".

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

Leveraging David Dehghan's answer above, the following works in Python 2.7.13:

from PyPDF2 import PdfFileWriter, PdfFileReader, PdfFileMerger

import StringIO

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter

packet = StringIO.StringIO()
# create a new PDF with Reportlab
can = canvas.Canvas(packet, pagesize=letter)
can.drawString(290, 720, "Hello world")
can.save()

#move to the beginning of the StringIO buffer
packet.seek(0)
new_pdf = PdfFileReader(packet)
# read your existing PDF
existing_pdf = PdfFileReader("original.pdf")
output = PdfFileWriter()
# add the "watermark" (which is the new pdf) on the existing page
page = existing_pdf.getPage(0)
page.mergePage(new_pdf.getPage(0))
output.addPage(page)
# finally, write "output" to a real file
outputStream = open("destination.pdf", "wb")
output.write(outputStream)
outputStream.close()

I know there are plenty of answers here, but I think git reset --soft HEAD~1 deserves some attention, because it let you keep changes in the last local (not pushed) commit while solving the diverged state. I think this is a more versatile solution than pull with rebase, because the local commit can be reviewed and even moved to another branch.

The key is using --soft, instead of the harsh --hard. If there is more than 1 commit, a variation of HEAD~x should work. So here are all the steps that solved my situation (I had 1 local commit and 8 commits in the remote):

1) git reset --soft HEAD~1 to undo local commit. For the next steps, I've used the interface in SourceTree, but I think the following commands should also work:

2) git stash to stash changes from 1). Now all the changes are safe and there's no divergence anymore.

3) git pull to get the remote changes.

4) git stash pop or git stash apply to apply the last stashed changes, followed by a new commit, if wanted. This step is optional, along with 2), when want to trash the changes in local commit. Also, when want to commit to another branch, this step should be done after switching to the desired one.

I have a feeling that you are rendering your section from within an @section in the _Layout file that is referring to a partial view with an @section, i.e. you've nested an @section within an @section. In the _Layout file, remove the @section around the rendersection.

Using display: fixed on the thead section should work, but for it only work on the current table in view, you will need the help of JavaScript. And it will be tricky because it will need to figure out scrolling places and location of elements relative to the viewport, which is one of the prime areas of browser incompatibility.

Have a look at the popular JavaScript frameworks (jQuery, MooTools, YUI, etc etc.) to see if they can either do what you want or make it easier to do what you want.

If anyone is looking at how to do this in .net core I accomplished it by adding the controller in startup

services.AddTransient<MyControllerIwantToInject>();

Then Injecting it into the other controller

public class controllerBeingInjectedInto : ControllerBase
{
    private readonly MyControllerIwantToInject _myControllerIwantToInject

     public controllerBeingInjectedInto(MyControllerIwantToInject myControllerIwantToInject)
{
       _myControllerIwantToInject = myControllerIwantToInject;
      }

Then just call it like so _myControllerIwantToInject.MyMethodINeed();

The best solution to your problem is probably to first export your dataframe to HTML and then convert it using an HTML-to-image tool. The final appearance could be tweaked via CSS.

Popular options for HTML-to-image rendering include:

• WeasyPrint
• wkhtmltopdf/wkhtmltoimage

Let us assume we have a dataframe named df. We can generate one with the following code:

import string
import numpy as np
import pandas as pd


np.random.seed(0)  # just to get reproducible results from `np.random`
rows, cols = 5, 10
labels = list(string.ascii_uppercase[:cols])
df = pd.DataFrame(np.random.randint(0, 100, size=(5, 10)), columns=labels)
print(df)
#     A   B   C   D   E   F   G   H   I   J
# 0  44  47  64  67  67   9  83  21  36  87
# 1  70  88  88  12  58  65  39  87  46  88
# 2  81  37  25  77  72   9  20  80  69  79
# 3  47  64  82  99  88  49  29  19  19  14
# 4  39  32  65   9  57  32  31  74  23  35

Using WeasyPrint

This approach uses a pip-installable package, which will allow you to do everything using the Python ecosystem. One shortcoming of weasyprint is that it does not seem to provide a way of adapting the image size to its content. Anyway, removing some background from an image is relatively easy in Python / PIL, and it is implemented in the trim() function below (adapted from here). One also would need to make sure that the image will be large enough, and this can be done with CSS's @page size property.

The code follows:

import weasyprint as wsp
import PIL as pil


def trim(source_filepath, target_filepath=None, background=None):
    if not target_filepath:
        target_filepath = source_filepath
    img = pil.Image.open(source_filepath)
    if background is None:
        background = img.getpixel((0, 0))
    border = pil.Image.new(img.mode, img.size, background)
    diff = pil.ImageChops.difference(img, border)
    bbox = diff.getbbox()
    img = img.crop(bbox) if bbox else img
    img.save(target_filepath)


img_filepath = 'table1.png'
css = wsp.CSS(string='''
@page { size: 2048px 2048px; padding: 0px; margin: 0px; }
table, td, tr, th { border: 1px solid black; }
td, th { padding: 4px 8px; }
''')
html = wsp.HTML(string=df.to_html())
html.write_png(img_filepath, stylesheets=[css])
trim(img_filepath)

Using wkhtmltopdf/wkhtmltoimage

This approach uses an external open source tool and this needs to be installed prior to the generation of the image. There is also a Python package, pdfkit, that serves as a front-end to it (it does not waive you from installing the core software yourself), but I will not use it.

wkhtmltoimage can be simply called using subprocess (or any other similar means of running an external program in Python). One would also need to output to disk the HTML file.

The code follows:

import subprocess


df.to_html('table2.html')
subprocess.call(
    'wkhtmltoimage -f png --width 0 table2.html table2.png', shell=True)

and its aspect could be further tweaked with CSS similarly to the other approach.

For positive numbers

unsigned int x, y, q;

To round up ...

q = (x + y - 1) / y;

or (avoiding overflow in x+y)

q = 1 + ((x - 1) / y); // if x != 0

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Good Luck...

You can use "lsof" to find open logfiles on your system. lsof just gives you a list of all open files.

Use grep for "log" ... use grep again for "php" (if the filename contains the strings "log" and "php" like in "php_error_log" and you are root user you will find the files without knowing the configuration).

        root@lnx-work:~# lsof |grep log
        ... snip
        gmain     12148 12274       user   13r      REG              252,1    32768     661814 /home/user/.local/share/gvfs-metadata/home-11ab0393.log

I believe the part regarding how to span rows has been answered thoroughly (i.e. by nesting rows), but I also ran into the issue of my nested rows not filling their container. While flexbox and negative margins are an option, a much easier solution is to use the predefined h-50 class on the row containing boxes 2, 3, 4, and 5.

Note: I am using Bootstrap-4, I just wanted to share because I ran into the same problem and found this to be a more elegant solution :)

Writing the properties file with multiple comments is not supported. Why ?

PropertyFile.java

public class PropertyFile extends Task {

    /* ========================================================================
     *
     * Instance variables.
     */

    // Use this to prepend a message to the properties file
    private String              comment;

    private Properties          properties;

The ant property file task is backed by a java.util.Properties class which stores comments using the store() method. Only one comment is taken from the task and that is passed on to the Properties class to save into the file.

The way to get around this is to write your own task that is backed by commons properties instead of java.util.Properties. The commons properties file is backed by a property layout which allows settings comments for individual keys in the properties file. Save the properties file with the save() method and modify the new task to accept multiple comments through <comment> elements.

from Eclipse main gui: select "Window->Show View->Other->General->Project Explorer" Double-clicking on "Project Explorer" brings up the "Project Explorer" window which shows every project in your workspace. That worked for me.

Good luck.

To expand on Solomon Rutzky's answer, if you are looking for a piece of data that shows up in a range (i.e. more than once but less than 5x), you can use

having count(*) > 1 and count(*) < 5

And you can use whatever qualifiers you desire in there - they don't have to match, it's all just included in the 'having' statement. https://webcheatsheet.com/sql/interactive_sql_tutorial/sql_having.php

Usually two arrays will have some small numeric errors,

You can use numpy.allclose(A,B), instead of (A==B).all(). This returns a bool True/False

grid is not present on nonrecursivecountcells's scope.

Either make grid a global array, or pass it as a parameter to the function.

Add:

• DELIMITER at the beginning and end of the SP.
• DROP PROCEDURE IF EXISTS validar_egreso; at the beginning
• When calling the SP, use @variableName.

This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).

DROP PROCEDURE IF EXISTS `validar_egreso`;

DELIMITER $$

CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
    IN codigo_producto VARCHAR(100),
    IN cantidad INT,
    OUT valido INT(11)
)
BEGIN

    DECLARE resta INT;
    SET resta = 0;

    SELECT (codigo_producto - cantidad) INTO resta;

    IF(resta > 1) THEN
       SET valido = 1;
    ELSE
       SET valido = -1;
    END IF;

    SELECT valido;
END $$

DELIMITER ;

-- execute the stored procedure
CALL validar_egreso(4, 1, @val);

-- display the result
select @val;

If you can use a Database project in Visual Studio, you can make your changes in the project and use schema compare to synchronize the changes to your database.

This way, dropping and recreating the dependent objects is handled by the change script.

It is also worth noting that in the cascade, an id (#) selector is more specific than a b (.) selector. Therefore, rules in the id statement will override rules in the class statement.

For example, if both of the following statements:

.headline {
  color:red;
  font-size: 3em;
}

#specials {
  color:blue;
  font-style: italic;
}

are applied to the same HTML element:

<h1 id="specials" class="headline">Today's Specials</h1>

the color:blue rule would override the color:red rule.

I'd like to find something official like this - 15.6.2.1 Clustered and Secondary Indexes - MySQL.

If the table has no PRIMARY KEY or suitable UNIQUE index, InnoDB internally generates a hidden clustered index named GEN_CLUST_INDEX on a synthetic column containing row ID values. The rows are ordered by the ID that InnoDB assigns to the rows in such a table. The row ID is a 6-byte field that increases monotonically as new rows are inserted. Thus, the rows ordered by the row ID are physically in insertion order.

So, why not create primary key or something like it by yourself? Besides, ORM cannot identify this hidden ID, meaning that you cannot use ID in your code.

I think what you're trying to do should be done with multiple Activities. If you're learning Android, understanding Activities is something you're going to have to tackle. Trying to write a whole app with just one Activity will end up being a lot more difficult. Read this article to get yourself started, then you should end up with something more like this:

View.OnClickListener handler = new View.OnClickListener(){
    public void onClick(View v) {

        switch (v.getId()) {

            case R.id.DownloadView: 
                // doStuff
                startActivity(new Intent(ThisActivity.this, DownloadActivity.class));
                break;
            case R.id.AppView: 
                // doStuff
                startActivity(new Intent(ThisActivity.this, AppActivity.class));
                break;
        }
    }
};

findViewById(R.id.DownloadView).setOnClickListener(handler);
findViewById(R.id.AppView).setOnClickListener(handler);

Suppose you want to create a vector x whose length is zero. Now let v be any vector.

> v<-c(4,7,8)
> v
[1] 4 7 8
> x<-v[0]
> length(x)
[1] 0

Use "selrow" to get the selected row Id

var myGrid = $('#myGridId');

var selectedRowId = myGrid.jqGrid("getGridParam", 'selrow');

and then use getRowData to get the selected row at index selectedRowId.

var selectedRowData = myGrid.getRowData(selectedRowId);

If the multiselect is set to true on jqGrid, then use "selarrrow" to get list of selected rows:

var selectedRowIds = myGrid.jqGrid("getGridParam", 'selarrrow');

Use loop to iterate the list of selected rows:

var selectedRowData;

for(selectedRowIndex = 0; selectedRowIndex < selectedRowIds .length; selectedRowIds ++) {

   selectedRowData = myGrid.getRowData(selectedRowIds[selectedRowIndex]);

}

ES6 solution:

import DefaultImage from '../assets/image.png';

const DEFAULT_IMAGE = Image.resolveAssetSource(DefaultImage).uri;

and then:

<Image source={{uri: DEFAULT_IMAGE}} />

Your if statement is setting the value. You want to compare it by doing this

if ($("#type").val() == "item1") {
 ...
}

daLizard is right though. You want an event handler. document.ready runs only once, when the page DOM is ready to be used.

If you are using svn with Jenkins on a Windows Server, you must accept https certificate using the same Jenkins's Windows service user.
So , if your Jenkins service runs as "MYSERVER\Administrator", you must use this command before all others, only one time of course :

runas /user:MYSERVER\Administrator "svn --username user --password password list https://myserver/svn/REPO "

svn asks you to accept the certificate and stores it in the right path.

After this you'll be able to use svn in jenkins job directly in a Windows batch command step.

for knowing the object properties var_dump(object) is the best way. It will show all public, private and protected properties associated with it without knowing the class name.

But in case of methods, you need to know the class name else i think it's difficult to get all associated methods of the object.

There is no "best way" to create an object. Each way has benefits depending on your use case.

The constructor pattern (a function paired with the new operator to invoke it) provides the possibility of using prototypal inheritance, whereas the other ways don't. So if you want prototypal inheritance, then a constructor function is a fine way to go.

However, if you want prototypal inheritance, you may as well use Object.create, which makes the inheritance more obvious.

Creating an object literal (ex: var obj = {foo: "bar"};) works great if you happen to have all the properties you wish to set on hand at creation time.

For setting properties later, the NewObject.property1 syntax is generally preferable to NewObject['property1'] if you know the property name. But the latter is useful when you don't actually have the property's name ahead of time (ex: NewObject[someStringVar]).

Hope this helps!

1. First of all you need to install Git software on your local development machine, e.g. Git Extensions.
2. Then do git init in the solution folder. That is the proper way to create a repository folder.
3. Set up a reasonable .gitignore file, so you don't commit unnecessary stuff.
4. git add
5. git commit
6. Add the proper remote, as described in your Team Foundation Server account git remote add origin <proper URL>
7. git push your code

Here's a fun way to do it with a decorator:

def restartable(func):
    def wrapper(*args,**kwargs):
        answer = 'y'
        while answer == 'y':
            func(*args,**kwargs)
            while True:
                answer = raw_input('Restart?  y/n:')
                if answer in ('y','n'):
                    break
                else:
                    print "invalid answer"
    return wrapper

@restartable
def main():
    print "foo"

main()

Ultimately, I think you need 2 while loops. You need one loop bracketing the portion which prompts for the answer so that you can prompt again if the user gives bad input. You need a second which will check that the current answer is 'y' and keep running the code until the answer isn't 'y'.

In 2018 here is what worked for me using MacOS HighSierra:

sudo lsof -nPi :yourPortNumber

then:

sudo kill -9 yourPIDnumber

Installing libffi-dev and re-installing python3.7 fixed the problem for me.

to cleanly build py 3.7 libffi-dev is required or else later stuff will fail

If using RHEL/Fedora:

yum install libffi-devel

or

sudo dnf install libffi-devel

If using Debian/Ubuntu:

sudo apt-get install libffi-dev

I first came across this back with ADO and classic asp, the answer i got was: performance. if you do a straight

added, it was a visible difference. something to do with table headers being returned as soon as the first condition is met, or some other craziness, anyway, it did speed things up.

Just use exception.ToString()

http://msdn.microsoft.com/en-us/library/system.exception.tostring.aspx

The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is null, its value is not included in the returned string.

If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not null.

exception.ToString() will also call .ToString() on that exception's inner exception, and so on...

If you are unaware of the position to replace, use list iterator to find and replace element ListIterator.set(E e)

ListIterator<String> iterator = list.listIterator();
while (iterator.hasNext()) {
     String next = iterator.next();
     if (next.equals("Two")) {
         //Replace element
         iterator.set("New");
     }
 }

I had this issue for dependencies that were created in other projects. Downloaded thirdparty dependencies showed up fine in the build path, but not a library that I had created.

SOLUTION: In the project that is not building correctly, right-click on the project and choose Properties, and then Maven. Uncheck the box labeled "Resolve dependencies from Workspace projects", hit Apply, and then OK. Right-click again on your project and do a Maven->Update Snapshots (or Update Dependencies) and your errors should go away when your project rebuilds (automatically if you have auto-build enabled).

I would suggest editing the /etc/default/jenkins

vi /etc/default/jenkins

And changing the $JENKINS_HOME variable (around line 23) to

JENKINS_HOME=/home/jenkins

Then restart the Jenkins with usual

/etc/init.d/jenkins start

Cheers!

The DOMContentLoaded event will fire as soon as the DOM hierarchy has been fully constructed, the load event will do it when all the images and sub-frames have finished loading.

DOMContentLoaded will work on most modern browsers, but not on IE including IE9 and above. There are some workarounds to mimic this event on older versions of IE, like the used on the jQuery library, they attach the IE specific onreadystatechange event.

Reflection is pretty "heavy"

Perhaps try this solution:

C#

if (item is IEnumerable) {
    foreach (object o in item as IEnumerable) {
            //do function
    }
} else {
    foreach (System.Reflection.PropertyInfo p in obj.GetType().GetProperties())      {
        if (p.CanRead) {
            Console.WriteLine("{0}: {1}", p.Name, p.GetValue(obj,  null)); //possible function
        }
    }
}

VB.Net

  If TypeOf item Is IEnumerable Then

    For Each o As Object In TryCast(item, IEnumerable)
               'Do Function
     Next
  Else
    For Each p As System.Reflection.PropertyInfo In obj.GetType().GetProperties()
         If p.CanRead Then
               Console.WriteLine("{0}: {1}", p.Name, p.GetValue(obj, Nothing))  'possible function
          End If
      Next
  End If

Reflection slows down +/- 1000 x the speed of a method call, shown in The Performance of Everyday Things

For Windows 10 the event ID for lock=4800 and unlock=4801.

As it says in the answer provided by Mario and User 00000, you will need to enable logging of lock and unlock events by using their method described above by running gpedit.msc and navigating to the branch they indicated:

Computer Configuration -> Windows Settings -> Security Settings -> Advanced Audit Policy Configuration -> System Audit Policies - Local Group Policy Object -> Logon/Logoff -> Audit Other Login/Logoff

Enable for both success and failure events.

After enabling logging of those events you can filter for Event ID 4800 and 4801 directly.

This method works for Windows 10 as I just used it to filter my security logs after locking and unlocking my computer.

The class definition defines the API for your class. In other words, it is a blueprint that defines the contract that exists between the class and its clients--all the other code that uses this class. The contract indicates which methods are available, how to call them, and what to expect in return.

But the class definition is a spec. Until you have an actual object of this class, the contract is just "a piece of paper." This is where the constructor comes in.

A constructor is the means of creating an instance of your class by creating an object in memory and returning a reference to it. Something that should happen in the constructor is that the object is in a proper initial state for the subsequent operations on the object to make sense.

This object returned from the constructor will now honor the contract specified in the class definition, and you can use this object to do real work.

Think of it this way. If you ever look at the Porsche website, you will see what it can do--the horsepower, the torque, etc. But it isn't fun until you have an actual Porsche to drive.

Hope that helps.

I would try one of the below mentioned methods. The example file that I use has the name dummy.txt. You can find the file here. I presume, that the file is in the same directory as the code (you can change fpath to include the proper file name and folder path.)

In both the below mentioned examples, the list that you want is given by lst.

1.> First method:

fpath = 'dummy.txt'
with open(fpath, "r") as f: lst = [line.rstrip('\n \t') for line in f]

print lst
>>>['THIS IS LINE1.', 'THIS IS LINE2.', 'THIS IS LINE3.', 'THIS IS LINE4.']

2.> In the second method, one can use csv.reader module from Python Standard Library:

import csv
fpath = 'dummy.txt'
with open(fpath) as csv_file:
    csv_reader = csv.reader(csv_file, delimiter='   ')
    lst = [row[0] for row in csv_reader] 

print lst
>>>['THIS IS LINE1.', 'THIS IS LINE2.', 'THIS IS LINE3.', 'THIS IS LINE4.']

You can use either of the two methods. Time taken for the creation of lst is almost equal in the two methods.

As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:

private _entityId: number;

constructor(private _route: ActivatedRoute) {
    // ...
}

ngOnInit() {
    // For a static snapshot of the route...
    this._entityId = this._route.snapshot.paramMap.get('id');

    // For subscribing to the observable paramMap...
    this._route.paramMap.pipe(
        switchMap((params: ParamMap) => this._entityId = params.get('id'))
    );

    // Or as an alternative, with slightly different execution...
    this._route.paramMap.subscribe((params: ParamMap) =>  {
        this._entityId = params.get('id');
    });
}

I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.

If the variant is empty then an error will be thrown. The bullet-proof code is the following:

Public Function GetLength(a As Variant) As Integer
   If IsEmpty(a) Then
      GetLength = 0
   Else
      GetLength = UBound(a) - LBound(a) + 1
   End If
End Function

I like some of the answers here, but there is a sed command that should do the trick on any platform:

sed 'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/'

Anyway, it's easy to understand. And knowing about the y command can come in handy sometimes.

We have a similar problem: the click event on a button doesn't work, as long as the user has not scrolled the page. The bug appears only on iOS.

We solved it by scrolling the page a little bit:

$('#modal-window').animate({scrollTop:$("#next-page-button-anchor").offset().top}, 500);

(It doesn't answer the ultimate cause, though. Maybe some kind of bug in Safari mobile ?)

JS:

function fun(obj) {
    var uid= $(obj).data('uid');
    var name= $(obj).data('name');
    var value= $(obj).data('value');
}

Just write a string to the output stream. You might set the MIME-type to text/javascript (edit: application/json is apparently officialer) if you're feeling helpful. (There's a small but nonzero chance that it'll keep something from messing it up someday, and it's a good practice.)

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

Try this explanation on...

TypeSafe means that variables are statically checked for appropriate assignment at compile time. For example, consder a string or an integer. These two different data types cannot be cross-assigned (ie, you can't assign an integer to a string nor can you assign a string to an integer).

For non-typesafe behavior, consider this:

object x = 89;
int y;

if you attempt to do this:

y = x;

the compiler throws an error that says it can't convert a System.Object to an Integer. You need to do that explicitly. One way would be:

y = Convert.ToInt32( x );

The assignment above is not typesafe. A typesafe assignement is where the types can directly be assigned to each other.

Non typesafe collections abound in ASP.NET (eg, the application, session, and viewstate collections). The good news about these collections is that (minimizing multiple server state management considerations) you can put pretty much any data type in any of the three collections. The bad news: because these collections aren't typesafe, you'll need to cast the values appropriately when you fetch them back out.

For example:

Session[ "x" ] = 34;

works fine. But to assign the integer value back, you'll need to:

int i = Convert.ToInt32( Session[ "x" ] );

Read about generics for ways that facility helps you easily implement typesafe collections.

C# is a typesafe language but watch for articles about C# 4.0; interesting dynamic possibilities loom (is it a good thing that C# is essentially getting Option Strict: Off... we'll see).

measure the square distance from one point to the other:

((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)) < d*d

where d is the distance, (x1,y1) are the coordinates of the 'base point' and (x2,y2) the coordinates of the point you want to check.

or if you prefer:

(Math.Pow(x1-x2,2)+Math.Pow(y1-y2,2)) < (d*d);

Noticed that the preferred one does not call Pow at all for speed reasons, and the second one, probably slower, as well does not call Math.Sqrt, always for performance reasons. Maybe such optimization are premature in your case, but they are useful if that code has to be executed a lot of times.

Of course you are talking in meters and I supposed point coordinates are expressed in meters too.

Set the DataGridView property

    gridView1.AutoGenerateColumns = true;

And make sure the list of objects your are binding, those object properties should be public.

and the version to work on the array type:

select
  array_to_string(
    array(select distinct unnest(zip_codes) from table),
    ', '
);

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

$secure_connection = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || (!empty($_SERVER['HTTP_HTTPS']) && $_SERVER['HTTP_HTTPS'] != 'off') || $_SERVER['REQUEST_SCHEME'] == 'https' || $_SERVER['SERVER_PORT'] == 443) ? true : false;

Code is checking anything possible and works also on IIS web server. Chrome since v44 do not set header HTTP: 1 so checking HTTP_HTTPS is OK. If this code does not match https it means your webserver or proxy server is poorly configured. Apache itself sets HTTPS flag correctly but there can be problem when you use proxy (e.g. nginx). You must set some header in nginx https virtual host

proxy_set_header   X-HTTPS 1;

and use some Apache module to set HTTPS flag correctly by looking for X-HTTPS from proxy. Search for mod_fakessl, mod_rpaf, etc.

Both git merge --squash and git rebase --interactive can produce a "squashed" commit.
But they serve different purposes.

• git merge --squash abranch

will produce a squashed commit on the destination branch, without marking any merge relationship.
(Note: it does not produce a commit right away: you need an additional git commit -m "squash branch")
This is useful if you want to throw away the source branch completely, going from (schema taken from SO question):

 git checkout stable

      X                   stable
     /                   
a---b---c---d---e---f---g tmp

to:

git merge --squash tmp
git commit -m "squash tmp"

      X-------------------G stable
     /                   
a---b---c---d---e---f---g tmp

and then deleting tmp branch.

Note: git merge has a --commit option, but it cannot be used with --squash. It was never possible to use --commit and --squash together.
Since Git 2.22.1 (Q3 2019), this incompatibility is made explicit:

See commit 1d14d0c (24 May 2019) by Vishal Verma (reloadbrain).
^{(Merged by Junio C Hamano -- gitster -- in commit 33f2790, 25 Jul 2019)}

merge: refuse --commit with --squash

Previously, when --squash was supplied, 'option_commit' was silently dropped. This could have been surprising to a user who tried to override the no-commit behavior of squash using --commit explicitly.

git/git builtin/merge.c#cmd_merge() now includes:

if (option_commit > 0)
    die(_("You cannot combine --squash with --commit."));

• git rebase --interactive

replays some or all of your commits on a new base, allowing you to squash (or more recently "fix up", see this SO question), going directly to:

git checkout tmp
git rebase -i stable

      stable
      X-------------------G tmp
     /                     
a---b

If you choose to squash all commits of tmp (but, contrary to merge --squash, you can choose to replay some, and squashing others).

So the differences are:

• squash does not touch your source branch (tmp here) and creates a single commit where you want.
• rebase allows you to go on on the same source branch (still tmp) with:
  • a new base
  • a cleaner history

Using furl and regex (python 3)

>>> import re
>>> import furl
>>> p = re.compile(r'(\/)+')
>>> url = furl.furl('/media/path').add(path='/js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media/path').add(path='js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media/path/').add(path='js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media///path///').add(path='//js///foo.js').url
>>> url
'/media///path/////js///foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'

This is the implemented code needed:

in Swift 3.0:

var dataString = String(data: fooData, encoding: String.Encoding.utf8)

or just

var dataString = String(data: fooData, encoding: .utf8)

Older swift version:

in Swift 2.0:

import Foundation

var dataString = String(data: fooData, encoding: NSUTF8StringEncoding)

in Swift 1.0:

var dataString = NSString(data: fooData, encoding:NSUTF8StringEncoding)

Same thing happened to me, and I also tried to terminate secondary process from task manager. Do not do that. It is not a solution, but rather a hack which may cause issues later. In my case, I was not even able to uninstall Visual Studio. I tried both web installation and ISO, same issue.

Here is how it worked finally. I restored my Windows 7 to earliest restore point as possible, when there was nothing installed, so I was sure that there would be no conflicts between the different tools (Java, Android API, etc.)

I started the installation of Visual Studio 2015 Community Release Candidate at 10 p.m. At 7 a.m., it was working on Android API 19-21. A hour later, it was finally preparing Visual Studio.

This means that all you need to do is to actually wait 8 to 9 hours. Don't terminate the secondary installer at risk of breaking your Visual Studio; just wait.

If that question is connected to your other Hudson questions use the command they provide. This way with XML from the command line:

$ curl -X POST -d '<run>...</run>' \
http://user:pass@myhost:myport/path/of/url

You need to change it a little bit to read from a file:

 $ curl -X POST -d @myfilename http://user:pass@myhost:myport/path/of/url

Read the manpage. following an abstract for -d Parameter.

-d/--data

(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F/--form.

-d/--data is the same as --data-ascii. To post data purely binary, you should instead use the --data-binary option. To URL-encode the value of a form field you may use --data-urlencode.

If any of these options is used more than once on the same command line, the data pieces specified will be merged together with a separating &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post chunk that looks like 'name=daniel&skill=lousy'.

If you start the data with the letter @, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin. The contents of the file must already be URL-encoded. Multiple files can also be specified. Posting data from a file named 'foobar' would thus be done with --data @foobar.

Try

document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'

You don't have Python Interpreter installed on your machine whereas Pycharm is looking for a Python interpreter, just go to https://www.python.org/downloads/ and download python and then create a new project, you'll be all set!

You could make it into a module and expose your inner function by returning it in an Object.

function outer() { 
    function inner() {
        console.log("hi");
    }
    return {
        inner: inner
    };
}
var foo = outer();
foo.inner();

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

If you're looking to do this XCode 5+, I found this is the easiest method:

Install ios-sim:

npm install -g ios-sim

Then simply execute:

ios-sim launch ./mySample.app --devicetypeid com.apple.CoreSimulator.SimDeviceType.iPhone-6

In which you can switch up your device type. Simple, fast, and it actually works.

Without creating new table you can do simply (e.g with mysqli):

1. get all columns
2. loop through all columns and remove wich you want
3. make your query

$r = mysqli_query('SELECT column_name FROM information_schema.columns WHERE table_name = table_to_query');

$c = count($r); while($c--) if($r[$c]['column_name'] != 'column_to_remove_from_query') $a[] = $r[$c]['column_name']; else unset($r[$c]);

$r = mysqli_query('SELECT ' . implode(',', $a) . ' FROM table_to_query');

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

There are multiple versions of the echo command, with different behaviors. Apparently the shell used for your script uses a version that doesn't recognize -n.

The printf command has much more consistent behavior. echo is fine for simple things like echo hello, but I suggest using printf for anything more complicated.

What system are you on, and what shell does your script use?

This works for me:

var tP = $("img").css("padding").split(" ");
var Padding = {
    Top: tP[0] != null ? parseInt(tP[0]) : 0,
    Right: tP[1] != null ? parseInt(tP[1]) : (tP[0] != null ? parseInt(tP[0]) : 0),
    Bottom: tP[2] != null ? parseInt(tP[2]) : (tP[0] != null ? parseInt(tP[0]) : 0),
    Left: tP[3] != null ? parseInt(tP[3]) : (tP[1] != null ? parseInt(tP[1]) : (tP[0] != null ? parseInt(tP[0]) : 0))
};

Result example:

Object {Top: 5, Right: 8, Bottom: 5, Left: 8}

To make a total:

var TotalPadding = Padding.Top + Padding.Right + Padding.Bottom + Padding.Left;

I just inherited an old VB.NET console application and needed to set up a Global Exception Handler. Since this question mentions VB.NET a few times and is tagged with VB.NET, but all the other answers here are in C#, I thought I would add the exact syntax for a VB.NET application as well.

Public Sub Main()
    REM Set up Global Unhandled Exception Handler.
    AddHandler System.AppDomain.CurrentDomain.UnhandledException, AddressOf MyUnhandledExceptionEvent

    REM Do other stuff
End Sub

Public Sub MyUnhandledExceptionEvent(ByVal sender As Object, ByVal e As UnhandledExceptionEventArgs)
    REM Log Exception here and do whatever else is needed
End Sub

I used the REM comment marker instead of the single quote here because Stack Overflow seemed to handle the syntax highlighting a bit better with REM.

If you mean, how to write something similar to this:

// switch statement
switch (string) {
  case "B1": 
    // do something
    break;
  /* more case "xxx" parts */
}

Then the canonical solution in C is to use an if-else ladder:

if (strcmp(string, "B1") == 0) 
{
  // do something
} 
else if (strcmp(string, "xxx") == 0)
{
  // do something else
}
/* more else if clauses */
else /* default: */
{
}

If you want to turn off app verification programmatically, you can do so with the following code:

boolean success = true;
boolean enabled = Settings.Secure.getInt(context.getContentResolver(), "package_verifier_enable", 1) == 1;
if (enabled) {
    success = Settings.Secure.putString(context.getContentResolver(), "package_verifier_enable", "0");
}

You will also need the following system permissions:

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

Also worth noting is that the "package_verifier_enable" string comes from the Settings.Glabal.PACKAGE_VERIFIER_ENABLE member which seems to be inaccessible.

Here's my answer for those that are Googling:

CSS:

.column {
    float: left;
    width: 50%;
}

/* Clear floats after the columns */
.container:after {
    content: "";
    display: table;
    clear: both;
}

Here's the HTML:

<div class="container">
    <div class="column"></div>
    <div class="column"></div>
</div>

I used to solve this issue by deleting the corresponding failed to download artifact directory in my local repo. Next time I run the maven command the artifact download is triggered again. Therefore I'd say it's a client side setting.

Nexus side (server repo side), this issue is solved configuring a scheduled task. Client side, this is done using -U, as you already pointed out.

The primary purpose is to avoid chained indexing and eliminate the SettingWithCopyWarning.

Here chained indexing is something like dfc['A'][0] = 111

The document said chained indexing should be avoided in Returning a view versus a copy. Here is a slightly modified example from that document:

In [1]: import pandas as pd

In [2]: dfc = pd.DataFrame({'A':['aaa','bbb','ccc'],'B':[1,2,3]})

In [3]: dfc
Out[3]:
    A   B
0   aaa 1
1   bbb 2
2   ccc 3

In [4]: aColumn = dfc['A']

In [5]: aColumn[0] = 111
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [6]: dfc
Out[6]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

Here the aColumn is a view and not a copy from the original DataFrame, so modifying aColumn will cause the original dfc be modified too. Next, if we index the row first:

In [7]: zero_row = dfc.loc[0]

In [8]: zero_row['A'] = 222
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [9]: dfc
Out[9]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time zero_row is a copy, so the original dfc is not modified.

From these two examples above, we see it's ambiguous whether or not you want to change the original DataFrame. This is especially dangerous if you write something like the following:

In [10]: dfc.loc[0]['A'] = 333
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [11]: dfc
Out[11]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time it didn't work at all. Here we wanted to change dfc, but we actually modified an intermediate value dfc.loc[0] that is a copy and is discarded immediately. It’s very hard to predict whether the intermediate value like dfc.loc[0] or dfc['A'] is a view or a copy, so it's not guaranteed whether or not original DataFrame will be updated. That's why chained indexing should be avoided, and pandas generates the SettingWithCopyWarning for this kind of chained indexing update.

Now is the use of .copy(). To eliminate the warning, make a copy to express your intention explicitly:

In [12]: zero_row_copy = dfc.loc[0].copy()

In [13]: zero_row_copy['A'] = 444 # This time no warning

Since you are modifying a copy, you know the original dfc will never change and you are not expecting it to change. Your expectation matches the behavior, then the SettingWithCopyWarning disappears.

Note, If you do want to modify the original DataFrame, the document suggests you use loc:

In [14]: dfc.loc[0,'A'] = 555

In [15]: dfc
Out[15]:
    A   B
0   555 1
1   bbb 2
2   ccc 3

The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.

When you're creating the table, you can create an IDENTITY column as follows:

CREATE TABLE (
  ID_column INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
  ...
);

The IDENTITY property will auto-increment the column up from number 1. (Note that the data type of the column has to be an integer.) If you want to add this to an existing column, use an ALTER TABLE command.

Edit:
Tested a bit, and I can't find a way to change the Identity properties via the Column Properties window for various tables. I guess if you want to make a column an identity column, you HAVE to use an ALTER TABLE command.

just click file in your android studio then click Sync Project with Gradle Files..

if it won't work, click Build click Clean Project.

it always work for me

One possible issue I see is you set your JSON unconventionally within an array/list object. I would recommend using JSON in its most accepted form, i.e.:

test_json = { "a": 1, "b": 2}

Once you do this, adding a json element only involves the following line:

test_json["c"] = 3

This will result in:

{'a': 1, 'b': 2, 'c': 3}

Afterwards, you can add that json back into an array or a list of that is desired.

I like a single line open and close:

if [ ]; then ##
    ...
    ...
fi; ##

The '##' helps me easily find the start and end to the block comment. I can stick a number after the '##' if I've got a bunch of them. To turn off the comment, I just stick a '1' in the '[ ]'. I also avoid some issues I've had with single-quotes in the commented block.

Here is the issue

  $total_result = $result->num_rows;

try this

<?php
if ($result = $mysqli->query("SELECT * FROM players ORDER BY id"))
{
    if ($result->num_rows > 0)
    {
        $total_result = $result->num_rows;
        $total_pages = ceil($total_result / $per_page);

        if(isset($_GET['page']) && is_numeric($_GET['page']))
        {
            $show_page = $_GET['page'];

            if ($show_page > 0 && $show_page <= $total_pages)
            {
                $start = ($show_page - 1) * $per_page;
                $end = $start + $per_page;
            }
            else
            {
                $start = 0;
                $end = $per_page;
            }               

        }
        else
        {
            $start = 0;
            $end = $per_page;
        }


        //display paginations
        echo "<p> View pages: ";
        for ($i=1; $i < $total_pages; $i++)
        { 
            if (isset($_GET['page']) && $_GET['page'] == $i)
            {
                echo  $i . " ";
            }
            else
            {
                echo "<a href='view-pag.php?$i'>" . $i . "</a> | ";
            }

        }
        echo "</p>";

    }
    else
    {
        echo "No result to display.";
    }

}
else
{
    echo "Error: " . $mysqli->error;
}


?>

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

If your minimum SDK is 23 or upper you could use this:

View childView = findViewById(R.id.your_view_id_in_the_scroll_view)
if(childView != null){
  scrollview.post(() -> scrollview.scrollToDescendant(childView));
}

public class JsonParsing {

public static Properties properties = null;

public static JSONObject jsonObject = null;

static {
    properties = new Properties();
}

public static void main(String[] args) {

    try {

        JSONParser jsonParser = new JSONParser();

        File file = new File("src/main/java/read.json");

        Object object = jsonParser.parse(new FileReader(file));

        jsonObject = (JSONObject) object;

        parseJson(jsonObject);

    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

public static void getArray(Object object2) throws ParseException {

    JSONArray jsonArr = (JSONArray) object2;

    for (int k = 0; k < jsonArr.size(); k++) {

        if (jsonArr.get(k) instanceof JSONObject) {
            parseJson((JSONObject) jsonArr.get(k));
        } else {
            System.out.println(jsonArr.get(k));
        }

    }
}

public static void parseJson(JSONObject jsonObject) throws ParseException {

    Set<Object> set = jsonObject.keySet();
    Iterator<Object> iterator = set.iterator();
    while (iterator.hasNext()) {
        Object obj = iterator.next();
        if (jsonObject.get(obj) instanceof JSONArray) {
            System.out.println(obj.toString());
            getArray(jsonObject.get(obj));
        } else {
            if (jsonObject.get(obj) instanceof JSONObject) {
                parseJson((JSONObject) jsonObject.get(obj));
            } else {
                System.out.println(obj.toString() + "\t"
                        + jsonObject.get(obj));
            }
        }
    }
}}

Another solution is to actually create or login the user automatically if you already have the credentials handy. Here is how I do it using Plain JS.

function loginToFirebase(callback)
{
    let email = '[email protected]';
    let password = 'xxxxxxxxxxxxxx';
    let config =
    {
        apiKey: "xxx",
        authDomain: "xxxxx.firebaseapp.com",
        projectId: "xxx-xxx",
        databaseURL: "https://xxx-xxx.firebaseio.com",
        storageBucket: "gs://xx-xx.appspot.com",
    };

    if (!firebase.apps.length)
    {
        firebase.initializeApp(config);
    }

    let database = firebase.database();
    let storage = firebase.storage();

    loginFirebaseUser(email, password, callback);
}

function loginFirebaseUser(email, password, callback)
{
    console.log('Logging in Firebase User');

    firebase.auth().signInWithEmailAndPassword(email, password)
        .then(function ()
        {
            if (callback)
            {
                callback();
            }
        })
        .catch(function(login_error)
        {
            let loginErrorCode = login_error.code;
            let loginErrorMessage = login_error.message;

            console.log(loginErrorCode);
            console.log(loginErrorMessage);

            if (loginErrorCode === 'auth/user-not-found')
            {
                createFirebaseUser(email, password, callback)
            }
        });
}

function createFirebaseUser(email, password, callback)
{
    console.log('Creating Firebase User');

    firebase.auth().createUserWithEmailAndPassword(email, password)
        .then(function ()
        {
            if (callback)
            {
                callback();
            }
        })
        .catch(function(create_error)
        {
            let createErrorCode = create_error.code;
            let createErrorMessage = create_error.message;

            console.log(createErrorCode);
            console.log(createErrorMessage);
        });
}

That is htmlFor in JSX and class is className in JSX

You are doing integer arithmetic, so there the result is correct. Try

percentage=((double)number/total)*100;

BTW the %f expects a double not a float. By pure luck that is converted here, so it works out well. But generally you'd mostly use double as floating point type in C nowadays.

You can dump JSON with double quote by:

import json

# mixing single and double quotes
data = {'jsonKey': 'jsonValue',"title": "hello world"}

# get string with all double quotes
json_string = json.dumps(data) 

You need to set the classpath to find your compiled class:

java -cp C:\Users\Matt\workspace\HelloWorld2\bin HelloWorld2

I think you can use async void for kicking off background operations as well, so long as you're careful to catch exceptions. Thoughts?

class Program {

    static bool isFinished = false;

    static void Main(string[] args) {

        // Kick off the background operation and don't care about when it completes
        BackgroundWork();

        Console.WriteLine("Press enter when you're ready to stop the background operation.");
        Console.ReadLine();
        isFinished = true;
    }

    // Using async void to kickoff a background operation that nobody wants to be notified about when it completes.
    static async void BackgroundWork() {
        // It's important to catch exceptions so we don't crash the appliation.
        try {
            // This operation will end after ten interations or when the app closes. Whichever happens first.
            for (var count = 1; count <= 10 && !isFinished; count++) {
                await Task.Delay(1000);
                Console.WriteLine($"{count} seconds of work elapsed.");
            }
            Console.WriteLine("Background operation came to an end.");
        } catch (Exception x) {
            Console.WriteLine("Caught exception:");
            Console.WriteLine(x.ToString());
        }
    }
}

I just pass them like this:

php5 script.php param1=blabla param2=yadayada

works just fine, the $_GET array is:

array(3) {
  ["script_php"]=>
  string(0) ""
  ["param1"]=>
  string(6) "blabla"
  ["param2"]=>
  string(8) "yadayada"
}

You can use the build in classes sun.misc.Base64Decoder and sun.misc.Base64Encoder to convert the binary data of the serialize to a string. You das not need additional classes because it are build in.

<style type="text/css">
  #nav-ask{ display:none; }
</style>

Solution using the destructuring assignment syntax of ES6:

var temp = { 'a' : 'apple', 'b' : 'banana', 'c' : 'carrot' };_x000D_
var { [Object.keys(temp).pop()]: lastItem } = temp;_x000D_
console.info(lastItem); //"carrot"

Easiest way is to just create an Item Decoration for your RecyclerView.

import android.graphics.Canvas;
import android.graphics.Rect;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class RecyclerSectionItemDecoration extends RecyclerView.ItemDecoration {

private final int             headerOffset;
private final boolean         sticky;
private final SectionCallback sectionCallback;

private View     headerView;
private TextView header;

public RecyclerSectionItemDecoration(int headerHeight, boolean sticky, @NonNull SectionCallback sectionCallback) {
    headerOffset = headerHeight;
    this.sticky = sticky;
    this.sectionCallback = sectionCallback;
}

@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
    super.getItemOffsets(outRect, view, parent, state);

    int pos = parent.getChildAdapterPosition(view);
    if (sectionCallback.isSection(pos)) {
        outRect.top = headerOffset;
    }
}

@Override
public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
    super.onDrawOver(c,
                     parent,
                     state);

    if (headerView == null) {
        headerView = inflateHeaderView(parent);
        header = (TextView) headerView.findViewById(R.id.list_item_section_text);
        fixLayoutSize(headerView,
                      parent);
    }

    CharSequence previousHeader = "";
    for (int i = 0; i < parent.getChildCount(); i++) {
        View child = parent.getChildAt(i);
        final int position = parent.getChildAdapterPosition(child);

XML for your header in recycler_section_header.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list_item_section_text"

And finally to add the Item Decoration to your RecyclerView:

RecyclerSectionItemDecoration sectionItemDecoration =
        new RecyclerSectionItemDecoration(getResources().getDimensionPixelSize(R.dimen.recycler_section_header_height),
                                          true, // true for sticky, false for not
                                          new RecyclerSectionItemDecoration.SectionCallback() {
                                              @Override
                                              public boolean isSection(int position) {
                                                  return position == 0
                                                      || people.get(position)
                                                               .getLastName()
                                                               .charAt(0) != people.get(position - 1)
                                                                                   .getLastName()
                                                                                   .charAt(0);

                                              @Override
                                              public CharSequence getSectionHeader(int position) {
                                                  return people.get(position)
                                                               .getLastName()
                                                               .subSequence(0,

                                              }
                                          });
    recyclerView.addItemDecoration(sectionItemDecoration);

With this Item Decoration you can either make the header pinned/sticky or not with just a boolean when creating the Item Decoration.

I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line

; On windows: extension_dir = "ext"

I changed it to:

; On windows: extension_dir = "C:\php\ext"

And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.

Some special characters give this type of error, so use

$query="INSERT INTO `tablename` (`name`, `email`)
VALUES
('$_POST[name]','$_POST[email]')";

I know this is an old question but this might help someone, it hasn't been addressed here.

I have been asked how to use rm -i in a script which is receiving input from a file. As file input to a script is normally received from STDIN we need to change it, so that only the response to the rm command is received from STDIN. Here's the solution:

#!/bin/bash
while read -u 3 line
do
 echo -n "Remove file $line?"
 read -u 1 -n 1 key
 [[ $key = "y" ]] &&  rm "$line"
 echo
done 3<filelist

If ANY key other than the "y" key (lower case only) is pressed, the file will not be deleted. It is not necessary to press return after the key (hence the echo command to send a new line to the display). Note that the POSIX bash "read" command does not support the -u switch so a workaround would need to be sought.

You can try it simply like this:

$length = 5;

$randomletter = substr(str_shuffle("abcdefghijklmnopqrstuvwxyz"), 0, $length);

I'm an Android newbie but here is the timer class I created based on the answers above. It works for my app but I welcome any suggestions.

Usage example:

...{
public Handler uiHandler = new Handler();

  private Runnable runMethod = new Runnable()
    {
        public void run()
        {
              // do something
        }
    };

    timer = new UITimer(handler, runMethod, timeoutSeconds*1000);       
        timer.start();
}...

public class UITimer
{
    private Handler handler;
    private Runnable runMethod;
    private int intervalMs;
    private boolean enabled = false;
    private boolean oneTime = false;

    public UITimer(Handler handler, Runnable runMethod, int intervalMs)
    {
        this.handler = handler;
        this.runMethod = runMethod;
        this.intervalMs = intervalMs;
    }

    public UITimer(Handler handler, Runnable runMethod, int intervalMs, boolean oneTime)
    {
        this(handler, runMethod, intervalMs);
        this.oneTime = oneTime;
    }

    public void start()
    {
        if (enabled)
            return;

        if (intervalMs < 1)
        {
            Log.e("timer start", "Invalid interval:" + intervalMs);
            return;
        }

        enabled = true;
        handler.postDelayed(timer_tick, intervalMs);        
    }

    public void stop()
    {
        if (!enabled)
            return;

        enabled = false;
        handler.removeCallbacks(runMethod);
        handler.removeCallbacks(timer_tick);
    }

    public boolean isEnabled()
    {
        return enabled;
    }

    private Runnable timer_tick = new Runnable()
    {
        public void run()
        {
            if (!enabled)
                return;

            handler.post(runMethod);

            if (oneTime)
            {
                enabled = false;
                return;
            }

            handler.postDelayed(timer_tick, intervalMs);
        }
    }; 
}

To launch facebook page from your app, let urlString = "fb://page/your_fb_page_id"

To launch facebook messenger let urlString = "fb-messenger://user/your_fb_page_id"

FB page id is usually numeric. To get it, goto Find My FB ID input your profile url, something like www.facebook.com/edgedevstudio then click "Find Numberic ID".

Voila, you now have your fb numeric id. replace "your_fb_page_id" with the generated Numeric ID

 val intent = Intent(Intent.ACTION_VIEW, Uri.parse(urlString))
 if (intent.resolveActivity(packageManager) != null) //check if app is available to handle the implicit intent
 startActivity(intent)

Assuming input of

{Anything}id={ID}{space}{Anything} 
{Anything}id={ID}{space}{Anything}

--

#! /bin/sh
while read s; do
   rhs=${s##*id=}
   id=${rhs%% *}
   echo $id # Do what you will with $id here
done <so.txt 

Or if it's always the 7th field

#! /bin/sh
while read f1 f2 f3 f4 f5 f6 f7 rest
do
echo ${f7##id=}
done <so.txt

Use FileInfo.Exists Property:

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
    log.Info("no files present")
}
foreach (var fi in TXTFiles)
    log.Info(fi.Exists);

or File.Exists Method:

string curFile = @"c:\temp\test.txt";
Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

There's no way of calling (eg) printf without knowing how many arguments you're passing to it, unless you want to get into naughty and non-portable tricks.

The generally used solution is to always provide an alternate form of vararg functions, so printf has vprintf which takes a va_list in place of the .... The ... versions are just wrappers around the va_list versions.

A solution is to create an Alias in your .gitconfig and call it easily:

[alias]
    tree = log --graph --decorate --pretty=oneline --abbrev-commit

And when you call it next time, you'll use:

git tree

To put it in your ~/.gitconfig without having to edit it, you can do:

git config --global alias.tree "log --graph --decorate --pretty=oneline --abbrev-commit"  

(If you don't use the --global it will put it in the .git/config of your current repo.)

As an alternative, you can also use an apply combined with format (or better with f-strings) which I find slightly more readable if one e.g. also wants to add a suffix or manipulate the element itself:

df = pd.DataFrame({'col':['a', 0]})

df['col'] = df['col'].apply(lambda x: "{}{}".format('str', x))

which also yields the desired output:

    col
0  stra
1  str0

If you are using Python 3.6+, you can also use f-strings:

df['col'] = df['col'].apply(lambda x: f"str{x}")

yielding the same output.

The f-string version is almost as fast as @RomanPekar's solution (python 3.6.4):

df = pd.DataFrame({'col':['a', 0]*200000})

%timeit df['col'].apply(lambda x: f"str{x}")
117 ms ± 451 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

%timeit 'str' + df['col'].astype(str)
112 ms ± 1.04 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Using format, however, is indeed far slower:

%timeit df['col'].apply(lambda x: "{}{}".format('str', x))
185 ms ± 1.07 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Grokking lookaround rapidly.
How to distinguish lookahead and lookbehind? Take 2 minutes tour with me:

(?=) - positive lookahead
(?<=) - positive lookbehind

Suppose

    A  B  C #in a line

Now, we ask B, Where are you?
B has two solutions to declare it location:

One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.

As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.

If you don't want to use pickle, you can store the list as text and then evaluate it:

data = [0,1,2,3,4,5]
with open("test.txt", "w") as file:
    file.write(str(data))

with open("test.txt", "r") as file:
    data2 = eval(file.readline())

# Let's see if data and types are same.
print(data, type(data), type(data[0]))
print(data2, type(data2), type(data2[0]))

[0, 1, 2, 3, 4, 5] class 'list' class 'int'

[0, 1, 2, 3, 4, 5] class 'list' class 'int'

I wrote small function for myself that works recursively in Postgres 9.4. I had same problem (good they did solve some of this headache in Postgres 9.5). Anyway here is the function (I hope it works well for you):

CREATE OR REPLACE FUNCTION jsonb_update(val1 JSONB,val2 JSONB)
RETURNS JSONB AS $$
DECLARE
    result JSONB;
    v RECORD;
BEGIN
    IF jsonb_typeof(val2) = 'null'
    THEN 
        RETURN val1;
    END IF;

    result = val1;

    FOR v IN SELECT key, value FROM jsonb_each(val2) LOOP

        IF jsonb_typeof(val2->v.key) = 'object'
            THEN
                result = result || jsonb_build_object(v.key, jsonb_update(val1->v.key, val2->v.key));
            ELSE
                result = result || jsonb_build_object(v.key, v.value);
        END IF;
    END LOOP;

    RETURN result;
END;
$$ LANGUAGE plpgsql;

Here is sample use:

select jsonb_update('{"a":{"b":{"c":{"d":5,"dd":6},"cc":1}},"aaa":5}'::jsonb, '{"a":{"b":{"c":{"d":15}}},"aa":9}'::jsonb);
                            jsonb_update                             
---------------------------------------------------------------------
 {"a": {"b": {"c": {"d": 15, "dd": 6}, "cc": 1}}, "aa": 9, "aaa": 5}
(1 row)

As you can see it analyze deep down and update/add values where needed.

If you mean that you can do this:

CREATE TABLE mytable_d (
ID          TINYINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
Name        VARCHAR(255) NOT NULL,
UNIQUE(Name)
) ENGINE=InnoDB;


ALTER TABLE mytable
ADD COLUMN DID tinyint(5) NOT NULL,
ADD CONSTRAINT mytable_ibfk_4 
      FOREIGN KEY (DID) 
        REFERENCES mytable_d (ID) ON DELETE CASCADE;

 > OK.

But then:

ALTER TABLE mytable
DROP KEY AID ;

gives error.

You can drop the index and create a new one in one ALTER TABLE statement:

ALTER TABLE mytable
DROP KEY AID ,
ADD UNIQUE KEY AID (AID, BID, CID, DID);

That is not how the PUBLIC_URL variable is used. According to the documentation, you can use the PUBLIC_URL in your HTML:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

Or in your JavaScript:

render() {
  // Note: this is an escape hatch and should be used sparingly!
  // Normally we recommend using `import` for getting asset URLs
  // as described in “Adding Images and Fonts” above this section.
  return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;
}

The PUBLIC_URL is not something you set to a value of your choosing, it is a way to store files in your deployment outside of Webpack's build system.

To view this, run your CRA app and add this to the src/index.js file:

console.log('public url: ', process.env.PUBLIC_URL)

You'll see the URL already exists.

Read more in the CRA docs.

TL;DR ...and late to the party, but that short explanation might help future googlers..

In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.

A minimal example:

df <- data.frame(a = 1:2); df$a <- 1:3

throws the error

Error in $<-.data.frame(*tmp*, a, value = 1:3) : replacement has 3 rows, data has 2

which is clear, because the vector a of df has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).

I think that the URI class is the one that you are looking for.

It's not a single command, but here's how I do it. The following script has been designed to run in SQL*Plus. Note, I've purposely written this to only work within the current schema.

set heading off

spool drop_constraints.out

select
    'alter table ' || 
    owner || '.' || 
    table_name || 
    ' disable constraint ' || -- or 'drop' if you want to permanently remove
    constraint_name || ';'
from
    user_constraints;

spool off

set heading on

@drop_constraints.out

To restrict what you drop, filter add a where clause to the select statement:-

• filter on constraint_type to drop only particular types of constraints
• filter on table_name to do it only for one or a few tables.

To run on more than the current schema, modify the select statement to select from all_constraints rather than user_constraints.

Note - for some reason I can't get the underscore to NOT act like an italicization in the previous paragraph. If someone knows how to fix it, please feel free to edit this answer.

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

you can extend LinkedHashSet adding your desired getIndex() method. It's 15 minutes to implement and test it. Just go through the set using iterator and counter, check the object for equality. If found, return the counter.

One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.

To avoid problems of side effects after changing env, especially using multiple nodes, it is better to set a temporary context.

One safe way to alter the environment is:

 withEnv(['MYTOOL_HOME=/usr/local/mytool']) {
    sh '$MYTOOL_HOME/bin/start'
 }

This approach does not poison the env after the command execution.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

Hashing is a one-way process but using a password-list you can regenerate the hashes and compare to the stored hash to 'crack' the password.

This site https://crackstation.net/ attempts to do this for you - run through passwords lists and tell you the cleartext password based on your hash.

If you want to download an image from https:

$output_filename = 'output.png';
$host = "https://.../source.png"; // <-- Source image url (FIX THIS)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($output_filename, 'wb');
fwrite($fp, $result);
fclose($fp);

1. Try this 2. and change the condition to "WINTER" and you will wonder:

public static void main(String[] args) {
  Season.add("Frühling");
  Season.add("Sommer");
  Season.add("Herbst");
  Season.add("WINTER");
  for (String s : Season) {
   if(!s.equals("Sommer")) {
    System.out.println(s);
    continue;
   }
   Season.remove("Frühling");
  }
 }

Instead of explicitly writing the class name you could use

this.getClass().getResource("/unibo/lsb/res/dice.jpg");

If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.

To trigger an event after ng-repeat has rendered try this directive:

var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
    restrict: 'A',
    link: function (scope, element, attr) {
        if (scope.$last === true) {
            $timeout(function () {
                scope.$emit('ngRepeatFinished');
            });
        }
    }
}
});

Complete example in angular: http://jsfiddle.net/ADukg/6880/

I got the directive from here: Use AngularJS just for routing purposes

Crash during development

Try my favourite tool logview to get the logs and analyze them during development.
Make sure to mark ./logview and ./lib/logview.jar as executable when running in Linux.

If you don't like it, there're a lot of alternative desktop log viewers for Android.

Crash in the wild

Integrate a real-time crash reporting tool such as Firebase Crashlytics in order to get stacktraces of unhandled exceptions which occurred on users' devices.

Read How to Release a Buggy App (And Live to Tell the Tale) to know more about handling bugs in the field.

Just multiply the number by -1 and check if the result is positive.

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

Since you want to append elements to existing list, you can use var List[Int] and then keep on adding elements to the same list. Note -> You have to make sure that you insert an element into existing list as follows:-

var l: List[int] = List() // creates an empty list

l = 3 :: l // adds 3 to the head of the list

l = 4 :: l // makes int 4 as the head of the list

// Now when you will print l, you will see two elements in the list ( 4, 3)

If your using Visual Studio just run the application with Crtl + F5 instead of F5. This will leave the console open when it's finished executing.

Using TSQL/MSSQL

You can use INTO keyword.

The result of SELECT into a real TABLE

Example: select .... INTO real_table_name

After

sp_help real_table_name

For me worked only adding the config or ssh_config file that was on the dir ~/.ssh/config on my Linux system on the c:\Program Files\Git\etc\ssh\ directory on Windows.

In some git versions we need to edit the C:\Users\<username>\AppData\Local\Programs\Git\etc\ssh\ssh_config file.

After that, I was able to use all the alias and settings that I normally used on my Linux connecting or pushing via SSH on the Git Bash.

You should take a look the reference documentation. It's well explained.

In your case, I think you cannot use between because you need to pass two parameters

Between - findByStartDateBetween … where x.startDate between ?1 and ?2

In your case take a look to use a combination of LessThan or LessThanEqual with GreaterThan or GreaterThanEqual

• LessThan/LessThanEqual

LessThan - findByEndLessThan … where x.start< ?1

LessThanEqual findByEndLessThanEqual … where x.start <= ?1

• GreaterThan/GreaterThanEqual

GreaterThan - findByStartGreaterThan … where x.end> ?1

GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1

You can use the operator And and Or to combine both.

I think maybe you are looking for an algorithm describing the distance between strings. Here are some you may refer to:

1. Hamming distance
2. Levenshtein distance
3. Damerau–Levenshtein distance
4. Jaro–Winkler distance

Assuming the terminal app in question is named 'app' (and you expect it to be in your $PATH):

if [[ ! `which app` ]]; then
    # run code if app not installed
else
    # run code if app is installed
fi

To import a specific Python file at 'runtime' with a known name:

import os
import sys

...

scriptpath = "../Test/"

# Add the directory containing your module to the Python path (wants absolute paths)
sys.path.append(os.path.abspath(scriptpath))

# Do the import
import MyModule

This solution worked for me

var ar = [];
$('#id option:selected').each(function(index,valor){
    ar.push(valor.value);
});
console.log(ar);

be sure to have your <option> tags with they correspondant value attribute. Hope it helps.

I prefer this:

<select>
   <option selected hidden>Choose here</option>
   <option value="1">One</option>
   <option value="2">Two</option>
   <option value="3">Three</option>
   <option value="4">Four</option>
   <option value="5">Five</option>
</select>

'Choose here' disappears after an option has been selected.

http://sfml-dev.org/documentation/2.0/classsf_1_1Music.php

SFML does not have mp3 support as another has suggested. What I always do is use Audacity and make all my music into ogg, and leave all my sound effects as wav.

Loading and playing a wav is simple (crude example):

http://www.sfml-dev.org/tutorials/2.0/audio-sounds.php

#include <SFML/Audio.hpp>
...
sf::SoundBuffer buffer;
if (!buffer.loadFromFile("sound.wav")){
    return -1;
}
sf::Sound sound;
sound.setBuffer(buffer);
sound.play();

Streaming an ogg music file is also simple:

#include <SFML/Audio.hpp>
...
sf::Music music;
if (!music.openFromFile("music.ogg"))
    return -1; // error
music.play();

You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.

used like: window.Promise https://www.npmjs.com/package/promise-polyfill

If you want more information on Polyfills check out the following MDN web doc https://developer.mozilla.org/en-US/docs/Glossary/Polyfill

 $(function () {
     $('input[type=checkbox]').click(function () {
         var chks = document.getElementById('<%= chkRoleInTransaction.ClientID %>').getElementsByTagName('INPUT');
         for (i = 0; i < chks.length; i++) {
            chks[i].checked = false;
         }
         if (chks.length > 1)
            $(this)[0].checked = true;
     });
 });
