REACT NATIVE

From your react native folder run:

cd android && gradlew clean

THEN

cd .. && react-native run-android

Notes:

For mac you may need to change gradlew to ./gradlew

For the command prompt you may need to change the && to &

For powershell you may need to change the && to ; and gradlew to .\gradlew.bat

Each command can also be run individually like so cd android then gradlew clean then cd .. then react-native run-android

Though there isn't any code equivalent to goto/label in Python, you could still get such functionality of goto/label using loops.

Lets take a code sample shown below where goto/label can be used in a arbitrary language other than python.

String str1 = 'BACK'

label1:
    print('Hello, this program contains goto code\n')
    print('Now type BACK if you want the program to go back to the above line of code. Or press the ENTER key if you want the program to continue with further lines of code')
    str1 = input()

if str1 == 'BACK'
    {
        GoTo label1
    }
print('Program will continue\nBla bla bla...\nBla bla bla...\nBla bla bla...')

Now the same functionality of the above code sample can be achieved in python by using a while loop as shown below.

str1 = 'BACK'

while str1 == 'BACK':
        print('Hello, this is a python program containing python equivalent code for goto code\n')
        print('Now type BACK if you want the program to go back to the above line of code. Or press the ENTER key if you want the program to continue with further lines of code')
        str1 = input()
print('Program will continue\nBla bla bla...\nBla bla bla...\nBla bla bla...')

You should be able to use:

$('#Edit.myClass, #Create.myClass').plugin({options here});

jQuery | Multiple Selectors

You use EXECUTENONQUERY() for INSERT,UPDATE and DELETE.

But for SELECT you must use EXECUTEREADER().........

You have to catch the SIGINT signal (we are talking POSIX right?)

See @Gab Royer´s answer for sigaction.

Example:

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

void my_handler(sig_t s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{
   signal (SIGINT,my_handler);

   while(1);
   return 0;

}

You can tell Eclipse to ignore these serialVersionUID warnings:

Window > Preferences > Java > Compiler > Errors / Warnings > Potential Programming Problems

In case you didn't know, there are a lot of other warnings you can enable in this section (or even have some reported as errors), many are very useful:

• Potential Programming Problems: Possible accidental boolean assignment
• Potential Programming Problems: Null pointer access
• Unnecessary code: Local variable is never read
• Unnecessary code: Redundant null check
• Unnecessary code: Unnecessary cast or 'instanceof'

and many more.

If you want a really hacky one-liner using regular expressions and interpolated strings...

const splitString = (value, idx) => value.split(new RegExp(`(?<=^.{${idx}})`));
console.log(splitString('abcdefgh', 5));

This code says split the string by replacing the value returned in the regex. The regex returns a position, not a character, so we don't lose in characters in the initial string. The way it does this is finding the position, via a look-behind and the ^ anchor, where there were index characters from the start of the string.

To solve your proposed problem of adding commas every third position from the end, the regex would be slightly different and we'd use replace rather than split.

const values = [ 8211, 98700, 1234567890 ];
const addCommas = (value, idx) => value.replace(new RegExp(`(?=(.{${idx}})+$)`, 'g'), ',');

console.log(values.map(v => addCommas(v.toString(), 3)));

Here we find the idxth position from the end by using a look-ahead and the $ anchor, but we also capture any number of those sets of positions from the end. Then we replace the position with a comma. We use the g flag (global) so it replaces every occurrence, not just the first found.

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

The other answers here fail to spell out a full solution for regex versions which don't support non-greedy matching. The greedy quantifiers (.*?, .+? etc) are a Perl 5 extension which isn't supported in traditional regular expressions.

If your stopping condition is a single character, the solution is easy; instead of

a(.*?)b

you can match

a[^ab]*b

i.e specify a character class which excludes the starting and ending delimiiters.

In the more general case, you can painstakingly construct an expression like

start(|[^e]|e(|[^n]|n(|[^d])))end

to capture a match between start and the first occurrence of end. Notice how the subexpression with nested parentheses spells out a number of alternatives which between them allow e only if it isn't followed by nd and so forth, and also take care to cover the empty string as one alternative which doesn't match whatever is disallowed at that particular point.

Of course, the correct approach in most cases is to use a proper parser for the format you are trying to parse, but sometimes, maybe one isn't available, or maybe the specialized tool you are using is insisting on a regular expression and nothing else.

Although it's more verbose than \w, I personally appreciate the readability of the full POSIX character class names ( http://www.zytrax.com/tech/web/regex.htm#special ), so I'd say:

^[[:alnum:]_]+$

However, while the documentation at the above links states that \w will "Match any character in the range 0 - 9, A - Z and a - z (equivalent of POSIX [:alnum:])", I have not found this to be true. Not with grep -P anyway. You need to explicitly include the underscore if you use [:alnum:] but not if you use \w. You can't beat the following for short and sweet:

^\w+$

Along with readability, using the POSIX character classes (http://www.regular-expressions.info/posixbrackets.html) means that your regex can work on non ASCII strings, which the range based regexes won't do since they rely on the underlying ordering of the ASCII characters which may be different from other character sets and will therefore exclude some non-ASCII characters (letters such as œ) which you might want to capture.

Updated with the theme() function, ggsave() and the code for the legend background:

df <- data.frame(y = d, x = 1, group = rep(c("gr1", "gr2"), 50))
p <- ggplot(df) +
  stat_boxplot(aes(x = x, y = y, color = group), 
               fill = "transparent" # for the inside of the boxplot
  ) 

Fastest way is using using rect, as all the rectangle elements inherit from rect:

p <- p +
  theme(
        rect = element_rect(fill = "transparent") # all rectangles
      )
    p

More controlled way is to use options of theme:

p <- p +
  theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent") # get rid of legend panel bg
  )
p

To save (this last step is important):

ggsave(p, filename = "tr_tst2.png",  bg = "transparent")

Please do not reinvent the wheel. There are many open-source & COTS solutions that already exist to solve this problem.

Please take a look at the following JavaScript libraries:

• Moment.js: [Source] | [Minified]

• Datejs: [Source] | [Alpha1.zip (1.6MB)]

Demo

I wrote a one-liner using Moment.js below. You can check out the demo here: JSFiddle.

moment('2014-08-20 15:30:00').format('MM/DD/YYYY h:mm a'); // 08/20/2014 3:30 pm

With out knowing exactly what your trying to accomplish here its hard to say but if your spending the time to solve this problem with javascript an AJAX request is going to be your best bet. However if you'd like to do it completely in PHP put this at the end of your script, and you should be set.

if(isset($_SERVER['HTTP_REFERER'])){
    header("Location: " . $_SERVER['HTTP_REFERER']);    
} else {
    echo "An Error";
}

This will still cause the page to change, twice, but the user will end on the page initiating the request. This is not even close to the right way to do this, and I highly recommend using an AJAX request, but it will get the job done.

Steps to convert .py to .exe in Python 3.6

1. Install Python 3.6.
2. Install cx_Freeze, (open your command prompt and type pip install cx_Freeze.
3. Install idna, (open your command prompt and type pip install idna.
4. Write a .py program named myfirstprog.py.
5. Create a new python file named setup.py on the current directory of your script.
6. In the setup.py file, copy the code below and save it.
7. With shift pressed right click on the same directory, so you are able to open a command prompt window.
8. In the prompt, type python setup.py build
9. If your script is error free, then there will be no problem on creating application.
10. Check the newly created folder build. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.

See the original script in my blog.

setup.py:

from cx_Freeze import setup, Executable

base = None    

executables = [Executable("myfirstprog.py", base=base)]

packages = ["idna"]
options = {
    'build_exe': {    
        'packages':packages,
    },    
}

setup(
    name = "<any name>",
    options = options,
    version = "<any number>",
    description = '<any description>',
    executables = executables
)

EDIT:

• be sure that instead of myfirstprog.py you should put your .pyextension file name as created in step 4;
• you should include each imported package in your .py into packages list (ex: packages = ["idna", "os","sys"])
• any name, any number, any description in setup.py file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = '' )
• the imported packages must be installed before you start step 8.

Change it to this:

var email = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;

This is a regular expression literal that is passed the i flag which means to be case insensitive.

Keep in mind that email address validation is hard (there is a 4 or 5 page regular expression at the end of Mastering Regular Expressions demonstrating this) and your expression certainly will not capture all valid e-mail addresses.

If there are duplicate keys then a key may correspond to more than one value. The obvious solution is to map the key to a list of these values.

For example in Python:

map = dict()
map["driver"] = list()
map["driver"].append("john")
map["driver"].append("mike")
print map["driver"]          # It shows john and mike
print map["driver"][0]       # It shows john
print map["driver"][1]       # It shows mike

From this post:

To get the entire PC CPU and Memory usage:

using System.Diagnostics;

Then declare globally:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Processor", "% Processor Time", "_Total"); 

Then to get the CPU time, simply call the NextValue() method:

this.theCPUCounter.NextValue();

This will get you the CPU usage

As for memory usage, same thing applies I believe:

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Memory", "Available MBytes");

Then to get the memory usage, simply call the NextValue() method:

this.theMemCounter.NextValue();

For a specific process CPU and Memory usage:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Process", "% Processor Time",              
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Process", "Working Set",
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?

To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters

The difference between Processor\% Processor Time and Process\% Processor Time is Processor is from the PC itself and Process is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters

An alternative to using the Performance Counter

Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

sudo arduino is the only way I get the Arduino IDE working (serial port and upload) on ubuntu 12.04 (64) Indeed the serial port to use is /dev/ttyACM0 in my case too. The other two (ttyS4 and ttyS0) gave an error when trying to upload to Uno. Have fun

Solution for this issue is:

1. Create another connection manager for your excel or flat files else you just have to pass variable values in connection string:

2. Right Click on Connection Manager>>properties>>Expression >>Select "ConnectionString" from drop down and pass the input variable like path , filename ..

i wrote a simple function for this:

Function (stringVar param)
(
    Local stringVar oneChar := '0';
    Local numberVar strLen := Length(param);
    Local numberVar index := strLen;

    oneChar = param[strLen];

    while index > 0 and oneChar = '0' do
    (
        oneChar := param[index];
        index := index - 1;
    );

    Left(param , index + 1);
)

If order is important you can create your own events and bind callbacks to fire when those events are triggered by other callbacks.

$('#mydiv').click(function(e) {
    // maniplate #mydiv ...
    $('#mydiv').trigger('mydiv-manipulated');
});

$('#mydiv').bind('mydiv-manipulated', function(e) {
    // do more stuff now that #mydiv has been manipulated
    return;
});

Something like that at least.

I was executing the whole command in one line, as it was mentioned as such

$ docker run --name testproject-agent \
-e TP_API_KEY="REPLACE_WITH_YOUR_KEY" \
-e TP_AGENT_ALIAS="My First Agent" \
testproject/agent:latest

But its supposed to be a multiline command, and I copied the command line by line and pressed enter after every line and bam! it worked.

Sometimes when you copy off of the web, the new-line character gets omitted, hence my suggestion to try manually introducing the new line.

For completeness, this is what you would have found in the svn book, had you known what to look for. It's what you've discovered already:

Undoing Changes

Resurrecting Deleted Items

Same thing, from the more recent (and detailed) version of the book:

Undoing Changes

Resurrecting Deleted Items

git stash show -p | git apply

and then git stash drop if you want to drop the stashed items.

Try to code below,

String[][] shades = new String[4][3];
for(int i = 0; i < 4; i++)
{
  for(int y = 0; y < 3; y++)
  {
    shades[i][y] = value;
  }
}

For "English locale" file names, this works nicely. I'm using this for sanitizing uploaded file names. The file name is not meant to be linked to anything on disk, it's for when the file is being downloaded hence there are no path checks.

$file_name = preg_replace('/([^\x20-~]+)|([\\/:?"<>|]+)/g', '_', $client_specified_file_name);

Basically it strips all non-printable and reserved characters for Windows and other OSs. You can easily extend the pattern to support other locales and functionalities.

if all you need is the names, use xpath instead. No need to do the iteration yourself and check for null.

string xml = @"
<root>
    <Employee name=""an"" />
    <Employee name=""nobyd"" />
    <Employee/>
</root>
";

var doc = new XmlDocument();

//doc.Load(path);
doc.LoadXml(xml);

var names = doc.SelectNodes("//Employee/@name");

Well, it partly depends what you want to happen if you're actually in a derived class.

For example, suppose SuperClass is in A.jar and SubClass is in B.jar, and you're executing code in an instance method declared in SuperClass but where this refers to an instance of SubClass. If you use this.getClass().getResource() it will look relative to SubClass, in B.jar. I suspect that's usually not what's required.

Personally I'd probably use Foo.class.getResourceAsStream(name) most often - if you already know the name of the resource you're after, and you're sure of where it is relative to Foo, that's the most robust way of doing it IMO.

Of course there are times when that's not what you want, too: judge each case on its merits. It's just the "I know this resource is bundled with this class" is the most common one I've run into.

Simple way in Java

public void resize(String inputImagePath,
            String outputImagePath, int scaledWidth, int scaledHeight)
            throws IOException {
        // reads input image
        File inputFile = new File(inputImagePath);
        BufferedImage inputImage = ImageIO.read(inputFile);
 
        // creates output image
        BufferedImage outputImage = new BufferedImage(scaledWidth,
                scaledHeight, inputImage.getType());
 
        // scales the input image to the output image
        Graphics2D g2d = outputImage.createGraphics();
        g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
        g2d.dispose();
 
        // extracts extension of output file
        String formatName = outputImagePath.substring(outputImagePath
                .lastIndexOf(".") + 1);
 
        // writes to output file
        ImageIO.write(outputImage, formatName, new File(outputImagePath));
    }

If you need the path and thedomain for each cookie, which get_dict() is not exposes, you can parse the cookies manually, for instance:

[
    {'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
    for c in session.cookies
]

Browser security prevents making an ajax call from a page hosted on one domain to a page hosted on a different domain; this is called the "same-origin policy".

The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.

Your css is almost correct. You are just missing display: block; in image css. Also one typo in your id. It should be <div id="ImageContainer">

img.Image { max-width: 100%; display: block; }_x000D_
div#ImageContainer { width: 600px; }

<div id="ImageContainer">_x000D_
    <img src="http://placehold.it/1000x600" class="Image">_x000D_
</div>

I can confirm this issue is due to pandas 0.23.

Uninstall and then reinstall 0.22.

pip uninstall pandas
pip install pandas==0.22

Hope this could solve the problem.

If you've just added the select option to a form and you wish to trigger the change event, I've found a setTimeout is required otherwise jQuery doesn't pick up the newly added select box:

window.setTimeout(function() { jQuery('.languagedisplay').change();}, 1);

My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.

I find datatable in library DT robust to handle rownames, and columnames

Library DT
datatable(df, rownames = FALSE)  # no row names 

refer to https://rstudio.github.io/DT/ for usage scenarios

You can use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom)

set 0 where you don't want images

Example for Drawable on the left:

TextView textView = (TextView) findViewById(R.id.myTxtView);
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0);

Alternatively, you can use setCompoundDrawablesRelativeWithIntrinsicBounds to respect RTL/LTR layouts.

Tip: Whenever you know any XML attribute but don't have clue about how to use it at runtime. just go to the description of that property in developer doc. There you will find Related Methods if it's supported at runtime . i.e. For DrawableLeft

Definitely works.

if [[ `pgrep -f $0` != "$$" ]]; then
        echo "Exiting ! Exist"
        exit
fi

I really did not want to post this as a comment because I would need to comment all answers and the original question.

All of the answers seem to rely on MSVCRT Microsoft Visual C Runtime. If you would like to avoid that dependency :

In case you want cross platform support, using the library here:

https://pypi.org/project/getkey/#files

https://github.com/kcsaff/getkey

Can allow for a more elegant solution.

Code example:

from getkey import getkey, keys
key = getkey()
if key == keys.UP:
  ...  # Handle the UP key
elif key == keys.DOWN:
  ...  # Handle the DOWN key
elif key == 'a':
  ...  # Handle the `a` key
elif key == 'Y':
  ...  # Handle `shift-y`
else:
  # Handle other text characters
  buffer += key
  print(buffer)

I had old MySQL and Centos OS (ver 6 I believe) that was not supported.
One day I couldn't access Plesk.
Using Filezilla, I copied files the database files from var/lib/mysql/databasename/ I then purchased a new server with new Centos 8 OS and MariaDB. In Plesk, I created a new database with the same name as my old one.
Using Filezilla, I then pasted the old database files into the newly created database folder. I could see the data in phpmyadmin but it was giving errors such as the ones described here. I happened to have an old sql backup dump file. I imported the dump file and it overwrote those files. I then pasted the old files back into var/lib/mysql/databasename/ I then had to do a repair in Plesk. To my suprise. It worked. I had over 6 months of order data restored and I didn't lose anything.

flatMap transform the items emitted by an Observable into new Observables, then flattens the emissions from those into a single Observable.

Check out the scenario below where get("posts") returns an Observable that is "flattened" by flatMap.

myObservable.map(e => get("posts")).subscribe(o => console.log(o));
// this would log Observable objects to console.  

myObservable.flatMap(e => get("posts")).subscribe(o => console.log(o));
// this would log posts to console.

Along with the already suggested methods of using a foreach loop, I thought I'd also mention that any object that implements IEnumerable also provides an IEnumerator interface via the GetEnumerator method. Although this method is usually not necessary, this can be used for manually iterating over collections, and is particularly useful when writing your own extension methods for collections.

IEnumerable<T> mySequence;
using (var sequenceEnum = mySequence.GetEnumerator())
{
    while (sequenceEnum.MoveNext())
    {
        // Do something with sequenceEnum.Current.
    }
}

A prime example is when you want to iterate over two sequences concurrently, which is not possible with a foreach loop.

myCars.Select((v, i) => new {car = v, index = i}).First(myCondition).index;

or the slightly shorter

myCars.Select((car, index) => new {car, index}).First(myCondition).index;

With sdk, you can't write to the root of internal storage. This cause your error.

Edit :

Based on your code, to use internal storage with sdk:

final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

Update

As of 2019 this can be easily achieved using ProgressIndicator, in Material Components library, used with the Widget.MaterialComponents.ProgressIndicator.Circular.Indeterminate style.

For more details please check Gabriele Mariotti's answer below.

Old implementation

Here is an awesome implementation of the material design circular intermediate progress bar https://gist.github.com/castorflex/4e46a9dc2c3a4245a28e. The implementation only lacks the ability add various colors like in inbox by android app but this does a pretty great job.

It's a part of ISO-8601 date representation. It's incomplete because a complete date representation in this pattern should also contains the date:

2015-03-04T00:00:00.000Z //Complete ISO-8601 date

If you try to parse this date as it is you will receive an Invalid Date error:

new Date('T00:00:00.000Z'); // Invalid Date

So, I guess the way to parse a timestamp in this format is to concat with any date

new Date('2015-03-04T00:00:00.000Z'); // Valid Date

Then you can extract only the part you want (timestamp part)

var d = new Date('2015-03-04T00:00:00.000Z');
console.log(d.getUTCHours()); // Hours
console.log(d.getUTCMinutes());
console.log(d.getUTCSeconds());

There is also an another actively developed alternative - JSCS — JavaScript Code Style:

JSCS is a code style linter for programmatically enforcing your style guide. You can configure JSCS for your project in detail using over 150 validation rules, including presets from popular style guides like jQuery, Airbnb, Google, and more.

It comes with multiple presets that you can choose from by simply specifying the preset in the .jscsrc configuration file and customize it - override, enable or disable any rules:

{
    "preset": "jquery",
    "requireCurlyBraces": null
}

There are also plugins and extensions built for popular editors.

• Perfect code, zero effort

I don't think you can. You may need to use an Iframe instead.

Please consider using some code like this:

SqlDataReader reader = command.ExecuteReader();
int numRows = 0;
DataTable dt = new DataTable();

dt.Load(reader);
numRows = dt.Rows.Count;

string attended_type = "";

for (int index = 0; index < numRows; index++)
{
    attended_type = dt.Rows[indice2]["columnname"].ToString();
}

reader.Close();

    curl -i -X 'POST' -F 'file=@/home/testeincremental.xlsx' 'http://example.com/upload.aspx?user=example&password=example123&type=XLSX'

You could use WITH to define your expressions. Then do a simple Sub-SELECT to access those definitions.

CREATE VIEW MyView
AS
  WITH MyVars (SomeVar, Var2)
  AS (
    SELECT
      'something' AS 'SomeVar',
      123 AS 'Var2'
  )

  SELECT *
  FROM MyTable
  WHERE x = (SELECT SomeVar FROM MyVars)

$.ajax({    
    type: 'POST',  
    url: 'test.php',  
    data:$("#Test-form").serialize(),  
    dataType:'json',
     beforeSend:function(xhr, settings){
     settings.data += '&moreinfo=MoreData';
     },
    success:function(data){
            //  json response  
    },
    error: function(data) { 
        // if error occured
    }
    });

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

one more case where this issue can occur,

if(a==b)
double c;
getValue(c);

here, the value is declared in a condition and then used outside it.

My code was broken because I was using a deprecated technique. It used to be this:

video.src = window.URL.createObjectURL(localMediaStream);
video.play();

Then I replaced that with this:

video.srcObject = localMediaStream;
video.play();

That worked beautifully.

EDIT: Recently localMediaStream has been deprecated and replaced with MediaStream. The latest code looks like this:

video.srcObject = new MediaStream();

References:

1. Deprecated technique: https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL
2. Modern deprecated technique: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject

Permission denied simply means the system is not having permission to write the file to that folder. Give permissions to the folder using "sudo chmod 777 " from terminal and try to run it. It worked for me.

Use

set dir="Your Folder Path Here"
rmdir /s %dir%
mkdir %dir%

This version deletes without asking:

set dir="Your Folder Here"
rmdir /s /q %dir%
mkdir %dir%

Example:

set dir="C:\foo1\foo\foo\foo3"
rmdir /s /q %dir%
mkdir %dir%

This will clear C:\foo1\foo\foo\foo3.

_{(I would like to mention Abdullah Sabouin's answer. There was a mix up about me copying him. I did not notice his post. I would like to thank you melpomene for pointing out errors!)}

Here is a more general generator function that skips any number of items from the beginning and end of an iterable:

def skip(iterable, at_start=0, at_end=0):
    it = iter(iterable)
    for x in itertools.islice(it, at_start):
        pass
    queue = collections.deque(itertools.islice(it, at_end))
    for x in it:
        queue.append(x)
        yield queue.popleft()

Example usage:

>>> list(skip(range(10), at_start=2, at_end=2))
[2, 3, 4, 5, 6, 7]

Try the Join-Path cmdlet:

Get-ChildItem c:\code\*\bin\* -Filter *.dll | Foreach-Object {
    Join-Path -Path  $_.DirectoryName -ChildPath "$buildconfig\$($_.Name)" 
}

For the sake of completeness (sometimes problems like this are not as complicated as they might seem):

Having a non-existing remote repository configured can also result in this behavior - I recently found out by accidentally changing my origin's URL to githu.com.

Easy as pie.

$(document).ready(function() {
   var referrer =  document.referrer;
});

Hope it helps. It is not always available though.

Sounds like you're looking for the time_ago_in_words method (or distance_of_time_in_words), from ActiveSupport. Call it like this:

<%= time_ago_in_words(timestamp) %>

I manually pass the variables to MSBuild on build server.

msbuild.exe MyProject.csproj "/p:TargetFrameworkSDKToolsDirectory=C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools" "/p:AspnetMergePath=C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools"

Simple and Efficient Solution : use Volley

 StringRequest stringRequest = new StringRequest(Request.Method.GET, finalUrl ,
           new Response.Listener<String>() {
                    @Override
                    public void onResponse(String){
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            HashMap<String, Object> responseHashMap = new HashMap<>(Utility.toMap(jsonObject)) ;
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("api", error.getMessage().toString());
            }
        });

        RequestQueue queue = Volley.newRequestQueue(context) ;
        queue.add(stringRequest) ;

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

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

Docs: man locale, man setlocale.

Your HTML should include quotes for attributes : http://jsfiddle.net/dKWnb/4/

Not required when using a HTML5 doctype - thanks @bazmegakapa

You create the array each time and add a value to it ... its working as expected ?

Moving the array outside of the live() function works fine :

var myarray = []; // more efficient than new Array()
$("#test").live("click",function() {
        myarray.push($("#drop").val());
        alert(myarray);
});

http://jsfiddle.net/dKWnb/5/

Also note that in later versions of jQuery v1.7 -> the live() method is deprecated and replaced by the on() method.

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

If you are on Linux, gitg is way to go to do it very quickly and graphically.

If you insist on command line you can use:

git log --oneline --decorate

To make git log nicer by default, I typically set these global preferences:

git config --global log.decorate true
git config --global log.abbrevCommit true

if x is numeric, then add scale_x_continuous(); if x is character/factor, then add scale_x_discrete(). This might solve your problem.

The tail program can do this:

ls -lart | tail -n +2

The -n +2 means “start passing through on the second line of output”.

CONVERT(DATE, <yourdatetime>) or CONVERT(DATE, GetDate()) or CONVERT(DATE, CURRENT_TIMESTAMP)

WeekMonth = CASE WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 22 THEN '5' 
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 15 THEN '4' 
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 8 THEN '3'
                 WHEN (DATEPART(day,TestDate) - datepart(dw,TestDate))>= 1 THEN '2' 
                 ELSE '1'
             END 

I ended up in this situation several times with my .NET 4.6.1 web site. I created the problem each time when I added a reference to a separate .NET Core project. Upon building, Visual Studio correctly alerted me that such cross-framework references are invalid, and I quickly deleted the project reference. The project built fine after that, but the System.Runtime error appeared when accessing the web site and refused to go away.

The fix each time was lame but effective: I deleted the project directory and redownloaded it from source control. Even though there was no difference between before and after, I was able to build the project and access the page with no complaints.

Here is the complete C# 7 solution...

switch (value)
{
   case var s when new[] { 1,2,3 }.Contains(s):
      // Do something
      break;
   case var s when new[] { 4,5,6 }.Contains(s):
      // Do something
      break;
   default:
      // Do the default
      break;
}

It works with strings too...

switch (mystring)
{
   case var s when new[] { "Alpha","Beta","Gamma" }.Contains(s):
      // Do something
      break;
...
}

Try the sp_foreachdb procedure.

I tried using the solution By @davy-c but had an Exception "System.FormatException: 'Input string was not in a correct format.'", this was due to there still being text past the line number, I modified the code he posted and came up with:

int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));

This works for me in VS2017 C#.

A wrapper class is a class that is used to wrap another class to add a layer of indirection and abstraction between the client and the original class being wrapped.

Take a look at the PDOStatement.fetchAll method. You could also use fetch in an iterator pattern.

Code sample for fetchAll, from the PHP documentation:

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();

/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll(\PDO::FETCH_ASSOC);
print_r($result);

Results:

Array
(
    [0] => Array
        (
            [NAME] => pear
            [COLOUR] => green
        )

    [1] => Array
        (
            [NAME] => watermelon
            [COLOUR] => pink
        )
)

As no one has mentioned - I would suggest to use great tool for such purpose - swaks

I have been using swaks to send email notifications from nagios via gmail for last 5 years without any problem.

We had this in many other cases, what we decided internally is to always have a wrapper for the controller/directive so that we don't need to think about it. Here is you example with our wrapper.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>

<script>
    function main($scope) {
        $scope.thisScope = $scope;
        $scope.testa = false;
        $scope.testb = false;
        $scope.testc = false;
        $scope.testd = false;
    }
</script>

<div ng-app >
    <div ng-controller="main">

        Test A: {{testa}}<br />
        Test B: {{testb}}<br />
        Test C: {{testc}}<br />
        Test D: {{testd}}<br />

        <div>
            testa (without ng-if): <input type="checkbox" ng-model="thisScope.testa" />
        </div>
        <div ng-if="!testa">
            testb (with ng-if): <input type="checkbox" ng-model="thisScope.testb" />
        </div>
        <div ng-show="!testa">
            testc (with ng-show): <input type="checkbox" ng-model="thisScope.testc" />
        </div>
        <div ng-hide="testa">
            testd (with ng-hide): <input type="checkbox" ng-model="thisScope.testd" />
        </div>

    </div>
</div>

Hopes this helps, Yishay

Code:

List<String> list = new ArrayList<String>();

list.add("a");

JSONArray array = new JSONArray();

for (int i = 0; i < list.size(); i++) {
    array.put(list.get(i));
}
JSONObject obj = new JSONObject();

try {
    obj.put("result", array);
} catch (JSONException e) {
    e.printStackTrace();
}

Change ng-disabled="!contractTypeValid" to [disabled]="!contractTypeValid"

Java 8 introduces the Instant.ofEpochSecond utility method for creating an Instant from a Unix timestamp, this can then be converted into a ZonedDateTime and finally formatted, e.g.:

final DateTimeFormatter formatter = 
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
        .atZone(ZoneId.of("GMT-4"))
        .format(formatter);

System.out.println(formattedDtm);   // => '2013-06-27 09:31:00'

I thought this might be useful for people who are using Java 8.

I got the same issue when i newly installed pycharm in my windows 10 machine.

• download python setup

• install this solved my problem.

for more help visit goodluck

During the install of python make sure you have "Install for all users" selected. Uninstall python and do a custom install and check "Install for all users"

In windows, if you need the a ${PWD} env variable in your docker-compose.yml you can creat a .env file in the same directory as your docker-compose.yml file then insert manualy the location of your folder.

CMD (pwd_var.bat) :

echo PWD=%cd% >> .env

Powershell (pwd_var.ps1) :

$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'; echo "PWD=$(get-location).path" >> .env

There is more good features hear for docker-compose .env variables: https://docs.docker.com/compose/reference/envvars/ especially for the COMPOSE_CONVERT_WINDOWS_PATHS env variable that allow docker compose to accept windows path with baskslash "\".

When you want to share a file on windows, the file must exist before sharing it with the container.

Problem is system is not able to find the file tools.jar

So first check that the file is there in the JDK installation of the directory.

Make the below entry in POM.xml as rightly pointed by others

<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.6</version>
<scope>system</scope>
<systemPath>C:\Program Files\Java\jdk1.8.0_241\lib\tools.jar</systemPath>
</dependency> 

then Follow the below steps also to remove the problem

1) Right Click on your project

2) Click on Build path

As per the below image, select the workspace default JRE and click on finish.

I came up with this CSS only method of rotating the screen using media queries. The queries are based on screen sizes that I found here. 480px seemed to be a good as no/few devices had more than 480px width or less than 480px height.

@media (max-height: 480px) and (min-width: 480px) and (max-width: 600px) { 
    html{
        -webkit-transform: rotate(-90deg);
           -moz-transform: rotate(-90deg);
            -ms-transform: rotate(-90deg);
             -o-transform: rotate(-90deg);
                transform: rotate(-90deg);
        -webkit-transform-origin: left top;
           -moz-transform-origin: left top;
            -ms-transform-origin: left top;
             -o-transform-origin: left top;
                transform-origin: left top;
        width: 320px; /*this is the iPhone screen width.*/
        position: absolute;
        top: 100%;
            left: 0
    }
}

findViewById(R.id.drawer_layout).setAlpha((float) 0.7);

R.id.drawer_layout is the id of the layout of which you want to dim the brightness.

You can try this... put parameters as :
http://localhost:8080/WebApplication11/webresources/generic/getText?arg1=hello in your browser...

package newpackage;

import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.DefaultValue;


import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PUT;
import javax.ws.rs.QueryParam;

@Path("generic")
public class GenericResource {

    @Context
    private UriInfo context;

    /**
     * Creates a new instance of GenericResource
     */
    public GenericResource() {
    }

    /**
     * Retrieves representation of an instance of newpackage.GenericResource

     * @return an instance of java.lang.String
     */
    @GET
    @Produces("text/plain")
    @Consumes("text/plain")
    @Path("getText/")
    public String getText(@QueryParam("arg1")
            @DefaultValue("") String arg1) {

       return  arg1 ;  }

    @PUT
    @Consumes("text/plain")
    public void putText(String content) {





    }
}

So I had the same issue, but it was because I was saving the access token but not using it. It could be because I'm super sleepy because of due dates, or maybe I just didn't think about it! But in case anyone else is in the same situation:

When I log in the user I save the access token:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$accessToken = $facebook->getAccessToken();
//save the access token for later

Now when I make requests to facebook I just do something like this:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$facebook->setAccessToken($accessToken);
$facebook->api(... insert own code here ...)

The original form is nearly perfect, you just have to omit prereq after CASE:

SELECT
  CASE
    WHEN prereq IS NULL THEN ' '
    ELSE prereq
  END AS prereq
FROM test;

I have found a way to use <base> and anchor based links. You can use JavaScript to keep links like #contact working as they have to. I used it in some parallax pages and it works for me.

<base href="http://www.mywebsite.com/templates/"><!--[if lte IE 6]></base><![endif]-->

...content...

<script>
var link='',pathname = window.location.href;
$('a').each(function(){
    link = $(this).attr('href');
    if(link[0]=="#"){
        $(this).attr('href', pathname + link);
    }
});
</script>

You should use at the end of the page

UPDATE `table_name` SET `test` = `number`

You can also do any mathematical changes in the process or use MySQL functions to modify the values.

By saying "Character array" you mean a string? Like "hello" or "hahaha this is a string of characters"..

Anyway, use strlen(). Read a bit about it, there's plenty of info about it, like here.

There is actually a python library called dataframe_image Just do a

pip install dataframe_image

Do the imports

import pandas as pd
import numpy as np
import dataframe_image as dfi
df = pd.DataFrame(np.random.randn(6, 6), columns=list('ABCDEF'))

and style your table if you want by:

df_styled = df.style.background_gradient() #adding a gradient based on values in cell

and finally:

dfi.export(df_styled,"mytable.png")

SELECT * FROM news WHERE date > DATE_SUB(NOW(), INTERVAL 24 HOUR)

At page translation time, the content of the file given in the include directive is ‘pasted’ as it is, in the place where the JSP include directive is used. Then the source JSP page is converted into a java servlet class. The included file can be a static resource or a JSP page. Generally, JSP include directive is used to include header banners and footers.

Syntax for include a jsp file:

<%@ include file="relative url">

Example

<%@include file="page_name.jsp" %>

Another possibility is that the result is not awaited on the client side. This can happen if any one method on the call stack does not use the await keyword to wait for the call to be completed.

It is impossible for both (?=foo) and (?=baz) to match at the same time. It would require the next character to be both f and b simultaneously which is impossible.

Perhaps you want this instead:

(?=.*foo)(?=.*baz)

This says that foo must appear anywhere and baz must appear anywhere, not necessarily in that order and possibly overlapping (although overlapping is not possible in this specific case because the letters themselves don't overlap).

One more solution:

• no toolbar but a segmented control (eyecandy)

  UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil 
                                                      delegate:nil
                                                      cancelButtonTitle:nil
                                                      destructiveButtonTitle:nil
                                                      otherButtonTitles:nil];
  
  [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
  
  CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
  
  UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
  pickerView.showsSelectionIndicator = YES;
  pickerView.dataSource = self;
  pickerView.delegate = self;
  
  [actionSheet addSubview:pickerView];
  [pickerView release];
  
  UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Close"]];
  closeButton.momentary = YES; 
  closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
  closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
  closeButton.tintColor = [UIColor blackColor];
  [closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
  [actionSheet addSubview:closeButton];
  [closeButton release];
  
  [actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
  
  [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
  

One way that also works is putting it this way in the first line of the your target:

your-target: $(eval SHELL:=/bin/bash)
    @echo "here shell is $$0"

For those of you want to copy the cURL output in the clipboard instead of outputting to a file, you can use pbcopy by using the pipe | after the cURL command.

Example: curl https://www.google.com/robots.txt | pbcopy. This will copy all the content from the given URL to your clipboard.

If you need both words are close each other, for example no more than 3 lines, you can do this:

find . -exec grep -Hn -C 3 "abc" {} \; | grep -C 3 "efg"

Same example but filtering only *.txt files:

find . -name *.txt -exec grep -Hn -C 3 "abc" {} \; | grep -C 3 "efg"

And also you can replace grep command with egrep command if you want also find with regular expressions.

Using this solution, you will also be able to put the cursor at the end of newly text.

final TextEditingController _controller = TextEditingController();

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Center(child: TextField(controller: _controller)),
    floatingActionButton: FloatingActionButton(
      onPressed: () {
        _controller.text = "Hello";

        // this changes cursor position
        _controller.selection = TextSelection.fromPosition(TextPosition(offset: _controller.text.length));
        setState(() {});
      },
    ),
  );
}

The use of file.exists() to test for the existence of the directory is a problem in the original post. If subDir included the name of an existing file (rather than just a path), file.exists() would return TRUE, but the call to setwd() would fail because you can't set the working directory to point at a file.

I would recommend the use of file_test(op="-d", subDir), which will return "TRUE" if subDir is an existing directory, but FALSE if subDir is an existing file or a non-existent file or directory. Similarly, checking for a file can be accomplished with op="-f".

Additionally, as described in another comment, the working directory is part of the R environment and should be controlled by the user, not a script. Scripts should, ideally, not change the R environment. To address this problem, I might use options() to store a globally available directory where I wanted all of my output.

So, consider the following solution, where someUniqueTag is just a programmer-defined prefix for the option name, which makes it unlikely that an option with the same name already exists. (For instance, if you were developing a package called "filer", you might use filer.mainDir and filer.subDir).

The following code would be used to set options that are available for use later in other scripts (thus avoiding the use of setwd() in a script), and to create the folder if necessary:

mainDir = "c:/path/to/main/dir"
subDir = "outputDirectory"

options(someUniqueTag.mainDir = mainDir)
options(someUniqueTag.subDir = "subDir")

if (!file_test("-d", file.path(mainDir, subDir)){
  if(file_test("-f", file.path(mainDir, subDir)) {
    stop("Path can't be created because a file with that name already exists.")
  } else {
    dir.create(file.path(mainDir, subDir))
  }
}

Then, in any subsequent script that needed to manipulate a file in subDir, you might use something like:

mainDir = getOption(someUniqueTag.mainDir)
subDir = getOption(someUniqueTag.subDir)
filename = "fileToBeCreated.txt"
file.create(file.path(mainDir, subDir, filename))

This solution leaves the working directory under the control of the user.

He's right. If you want to stay with jQuery you could do this

var ctx = $('#myChart')[0];
ctx.height = 500;

or

var ctx = $('#myChart');
ctx.attr('height',500);

If you are not sure if local db is installed, or not sure which database name you should use to connect to it - try running 'sqllocaldb info' command - it will show you existing localdb databases.

Now, as far as I know, local db should be installed together with Visual Studio 2015. But probably it is not required feature, and if something goes wrong or it cannot be installed for some reason - Visual Studio installation continues still (note that is just my guess). So to be on the safe side don't rely on it will always be installed together with VS.

This way work for me:

  @Override
protected void onCreate(Bundle savedInstanceState) {
    setTheme(GApplication.getInstance().getTheme());
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
}

Then you want to change a new theme:

GApplication.getInstance().setTheme(R.style.LightTheme);
recreate();

In rails 5, as per the instructions in Rails Guides, you can use:

redirect_back(fallback_location: root_path)

The 'back' location is pulled from the HTTP_REFERER header which is not guaranteed to be set by the browser. Thats why you should provide a 'fallback_location'.

That looks like it might belong in the select statement:

SELECT id, col1, col2, col3, (CASE WHEN table3.col3 IS NULL THEN table2.col3 AS col4 ELSE table3.col3 as col4 END)
FROM table1
LEFT OUTER JOIN table2
ON table1.id = table2.id
LEFT OUTER JOIN table3
ON table1.id = table3.id

Try creating an inline table-valued function. Example:

CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
RETURNS TABLE
AS
RETURN
(
    SELECT Field1, Field2
    FROM SomeTable
    WHERE Field3 = @Parameter1
)

-- Then call like this, just as if it's a table/view just with a parameter
SELECT * FROM dbo.fxnExample(1)

If you view the execution plan for the SELECT you will not see a mention of the function at all and will actually just show you the underlying tables being queried. This is good as it means statistics on the underlying tables will be used when generating an execution plan for the query.

The thing to avoid would be a multi-statement table valued function as underlying table statistics will not be used and can result in poor performance due to a poor execution plan.
Example of what to avoid:

CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
    RETURNS @Results TABLE(Field1 VARCHAR(10), Field2 VARCHAR(10))
AS
BEGIN
    INSERT @Results
    SELECT Field1, Field2
    FROM SomeTable
    WHERE Field3 = @Parameter1

    RETURN
END

Subtly different, but with potentially big differences in performance when the function is used in a query.

Just as a note you can also use this for iPads:

activityViewController.popoverPresentationController?.sourceView = sender

So the popover pops from the sender (the button in that case).

Drop multiple columns like this:

cols = [1,2,4,5,12]
df.drop(df.columns[cols],axis=1,inplace=True)

inplace=True is used to make the changes in the dataframe itself without doing the column dropping on a copy of the data frame. If you need to keep your original intact, use:

df_after_dropping = df.drop(df.columns[cols],axis=1)

I think you want to give Share button, clicking on which the suitable media/website option should be there to share with it. In Android, you need to create createChooser for the same.

Sharing Text:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "This is the text that will be shared.");
startActivity(Intent.createChooser(sharingIntent,"Share using"));

Sharing binary objects (Images, videos etc.)

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);

sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

FYI, above code are referred from Sharing content in Android using ACTION_SEND Intent

This post will go through the following topics:

• Merging with index under different conditions

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

You can do like below to make setTimeout pausable on server side (Node.js)

const PauseableTimeout = function(callback, delay) {
    var timerId, start, remaining = delay;

    this.pause = function() {
        global.clearTimeout(timerId);
        remaining -= Date.now() - start;
    };

    this.resume = function() {
        start = Date.now();
        global.clearTimeout(timerId);
        timerId = global.setTimeout(callback, remaining);
    };

    this.resume();
};

and you can check it as below

var timer = new PauseableTimeout(function() {
    console.log("Done!");
}, 3000);
setTimeout(()=>{
    timer.pause();
    console.log("setTimeout paused");
},1000);

setTimeout(()=>{
    console.log("setTimeout time complete");
},3000)

setTimeout(()=>{
    timer.resume();
    console.log("setTimeout resume again");
},5000)

This looks like a Json array list.Therefore its best to use ArrayList to handle the data. In your api end point add array list like this

 @GET("places/")
Call<ArrayList<Place>> getNearbyPlaces(@Query("latitude") String latitude, @Query("longitude") String longitude);

You can use the onChange property. Something like:

<select onChange="window.location.href=this.value">
    <option value="www.google.com">A</option>
    <option value="www.aol.com">B</option>
</select>

Either one should work OK. In fact, System.Threading.Timer uses System.Timers.Timer internally.

Having said that, it's easy to misuse System.Timers.Timer. If you don't store the Timer object in a variable somewhere, then it is liable to be garbage collected. If that happens, your timer will no longer fire. Call the Dispose method to stop the timer, or use the System.Threading.Timer class, which is a slightly nicer wrapper.

What problems have you seen so far?

In the meantime urllib2 seems to verify server certificates by default. The warning, that was shown in the past disappeared for 2.7.9 and I currently ran into this problem in a test environment with a self signed certificate (and Python 2.7.9).

My evil workaround (don't do this in production!):

import urllib2
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

urllib2.urlopen("https://your-test-server.local", context=ctx)

According to docs calling SSLContext constructor directly should work, too. I haven't tried that.

If Git for windows is installed, run Git Bash shell:

  bash

You can run ssh from within Bash shell (Bash is aware of the path of ssh)

To know the exact path of ssh, run "where" command in Bash shell:

  $ where ssh

you get:

  c:\Program Files\Git\usr\bin\ssh.exe

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

Note: Using Bootstrap 4 classes.

You can also use a dict comprehension like:

with open("infile.txt") as f:
    d = {int(k): v for line in f for (k, v) in [line.strip().split(None, 1)]}

Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT

Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.

The below should work

describe "#foo"
  it "should call 'bar' with appropriate arguments" do
     subject.stub(:bar)
     subject.foo
     expect(subject).to have_received(:bar).with("Invalid number of arguments")
  end
end

Just want to reiterate this will work in pandas >= 0.9.1:

In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]: 
                           ID
0  00013007854817840016671868
1  00013007854817840016749251
2  00013007854817840016754630
3  00013007854817840016781876
4  00013007854817840017028824
5  00013007854817840017963235
6  00013007854817840018860166

I'm creating an issue about detecting integer overflows also.

EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247

Update as it helps others:

To have all columns as str, one can do this (from the comment):

pd.read_csv('sample.csv', dtype = str)

To have most or selective columns as str, one can do this:

# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str'  for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)

This will convert an integer to a 2 digit hex string with the 0x prefix:

strHex = "0x%0.2X" % 255

1. <TouchableHighlight> element can have only one child inside
2. Make sure that you have imported Image

All answers are correct with sc.textFile

I was just wondering why not wholeTextFiles For example, in this case...

val minPartitions = 2
val path = "/pathtohdfs"
    sc.wholeTextFiles(path,minPartitions)
      .flatMap{case (path, text) 
    ...

one limitation is that, we have to load small files otherwise performance will be bad and may lead to OOM.

Note :

• The wholefile should fit in to memory
• Good for file formats that are NOT splittable by line... such as XML files

Case 1:Only two activity A and B:

Here Activity flow is A->B .On clicking backbutton from B we need to close the application then while starting Activity B from A just call finish() this will prevent android from storing Activity A in to the Backstack.eg for activity A is Loding/Splash screen of application.

Intent newIntent = new Intent(A.this, B.class);
startActivity(newIntent);
finish();

Case 2:More than two activitiy:

If there is a flow like A->B->C->D->B and on clicking back button in Activity B while coming from Activity D.In that case we should use.

Intent newIntent = new Intent(D.this,B.class);
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);

Here Activity B will be started from the backstack rather than a new instance because of Intent.FLAG_ACTIVITY_CLEAR_TOP and Intent.FLAG_ACTIVITY_NEW_TASK clears the stack and makes it the top one.So when we press back button the whole application will be terminated.

for i in A:
    print('\t'.join(map(str, i)))

Since Spring 3.1 the id attribute is an xsd:string and permits the same range of characters as the name attribute.

The only difference between an id and a name is that a name can contain multiple aliases separated by a comma, semicolon or whitespace, whereas an id must be a single value.

From the Spring 3.2 documentation:

In XML-based configuration metadata, you use the id and/or name attributes to specify the bean identifier(s). The id attribute allows you to specify exactly one id. Conventionally these names are alphanumeric ('myBean', 'fooService', etc), but may special characters as well. If you want to introduce other aliases to the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was typed as an xsd:ID, which constrained possible characters. As of 3.1, it is now xsd:string. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers.

'[{"event":"inbound","ts":1426249238}]' is a string, you cannot access any properties there. You will have to parse it to an object, with JSON.parse() and then handle it like a normal object

for installing multiple packages, i am using a setup.py file with following code:

import sys
import subprocess
import pkg_resources

required = {'numpy','pandas','<etc>'} 
installed = {pkg.key for pkg in pkg_resources.working_set}
missing = required - installed


if missing:
    # implement pip as a subprocess:
    subprocess.check_call([sys.executable, '-m', 'pip', 'install',*missing])

Deleting files and folders

If you want to delete an item from the repository, but keep it locally as an unversioned file/folder, use Extended Context Menu ? Delete (keep local). You have to hold the Shift key while right clicking on the item in the explorer list pane (right pane) in order to see this in the extended context menu.

Delete completely:
right mouse click ? Menu ? Delete

Delete & Keep local:
Shift + right mouse click ? Menu ? Delete

You can access the keys with ${!array[@]}:

bash-4.0$ echo "${!array[@]}"
foo bar

Then, iterating over the key/value pairs is easy:

for i in "${!array[@]}"
do
  echo "key :" $i
  echo "value:" ${array[$i]}
done

You should use is as follows:

DECIMAL(m,a)

m is the number of total digits your decimal can have.

a is the max number of digits you can have after the decimal point.

The new cv2 interface for Python integrates numpy arrays into the OpenCV framework, which makes operations much simpler as they are represented with simple multidimensional arrays. For example, your question would be answered with:

import cv2  # Not actually necessary if you just want to create an image.
import numpy as np
blank_image = np.zeros((height,width,3), np.uint8)

This initialises an RGB-image that is just black. Now, for example, if you wanted to set the left half of the image to blue and the right half to green , you could do so easily:

blank_image[:,0:width//2] = (255,0,0)      # (B, G, R)
blank_image[:,width//2:width] = (0,255,0)

If you want to save yourself a lot of trouble in future, as well as having to ask questions such as this one, I would strongly recommend using the cv2 interface rather than the older cv one. I made the change recently and have never looked back. You can read more about cv2 at the OpenCV Change Logs.

If you want to update a single gem to a specific version:

1. change the version of the gem in the Gemfile
2. bundle update

There's no easy CSS only solution. You could do this:

• Find all instances of background-color and color in your CSS file and create a class name for each unique color.

  .top-header { color: #fff; }
  .content-text { color: #f00; }
  .bg-leftnav { background-color: #fff; }
  .bg-column { background-color: #f00; }
  

• Next go through every single page on your site where color was involved and add the appropriate classes for both color and background color.

• Last, remove any references of colors in your CSS other than your newly created color classes.

an easy solution is to install the module using python -m pip install <library-name> instead of pip install <library-name> you may use sudo in case of admin restrictions

This can done several ways. I usually do it from my class.

From class

.image
{
    width:100%;


}

and for this your html would be:

<img class="image" src="images/image_name">

or if you want to style it using inline styling then you would just have:

<img style="width:100%; height:60px" id="image" src="images/image_name">

I however recommend doing it from your external style-sheet because as your project grows you will realize that the entire thing is easier managed with separate files for your html and your css.

if (nfile.eof()) // Prompt data from the Priming read:
    nfile >> CODE >> QTY >> PRICE;
else
{
    /*used to check that the file is not empty*/
    ofile << "empty file!!" << endl;
    return 1;
}

It works.

For those who encounter the same problem.

It helps to install a python package foo on your machine (can also be in virtualenv) so that you can import the package foo from other projects and also from [I]Python prompts.

It does the similar job of pip, easy_install etc.,

Using setup.py

Let's start with some definitions:

Package - A folder/directory that contains __init__.py file.
Module - A valid python file with .py extension.
Distribution - How one package relates to other packages and modules.

Let's say you want to install a package named foo. Then you do,

$ git clone https://github.com/user/foo  
$ cd foo
$ python setup.py install

Instead, if you don't want to actually install it but still would like to use it. Then do,

$ python setup.py develop  

This command will create symlinks to the source directory within site-packages instead of copying things. Because of this, it is quite fast (particularly for large packages).

Creating setup.py

If you have your package tree like,

foo
+-- foo
¦   +-- data_struct.py
¦   +-- __init__.py
¦   +-- internals.py
+-- README
+-- requirements.txt
+-- setup.py

Then, you do the following in your setup.py script so that it can be installed on some machine:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['bar', 'greek'], #external packages as dependencies
)

Instead, if your package tree is more complex like the one below:

foo
+-- foo
¦   +-- data_struct.py
¦   +-- __init__.py
¦   +-- internals.py
+-- README
+-- requirements.txt
+-- scripts
¦   +-- cool
¦   +-- skype
+-- setup.py

Then, your setup.py in this case would be like:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

Add more stuff to (setup.py) & make it decent:

from setuptools import setup

with open("README", 'r') as f:
    long_description = f.read()

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   license="MIT",
   long_description=long_description,
   author='Man Foo',
   author_email='[email protected]',
   url="http://www.foopackage.com/",
   packages=['foo'],  #same as name
   install_requires=['bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

The long_description is used in pypi.org as the README description of your package.

And finally, you're now ready to upload your package to PyPi.org so that others can install your package using pip install yourpackage.

First step is to claim your package name & space in pypi using:

$ python setup.py register

Once your package name is registered, nobody can claim or use it. After successful registration, you have to upload your package there (to the cloud) by,

$ python setup.py upload

Optionally, you can also sign your package with GPG by,

$ python setup.py --sign upload

Bonus Reading:

• See a sample setup.py from a real project here: torchvision-setup.py

• PEP 517, setuptools

You need to specify the encoding of the InputStreamReader using the Charset parameter.

Charset inputCharset = Charset.forName("ISO-8859-1");
InputStreamReader isr = new InputStreamReader(fis, inputCharset));

This is work for me. i hope to help you.

Use the bootstrap classes col-xx-# and col-xx-offset-#

So what is happening here is your screen is getting divided into 12 columns. In col-xx-#, # is the number of columns you cover and offset is the number of columns you leave.

For xx, in a general website, md is preferred and if you want your layout to look the same in a mobile device, xs is preferred.

With what I can make of your requirement,

<div class="row">
  <div class="col-md-4">First Div</div>
  <div class="col-md-8">Second DIV </div>
</div>

Should do the trick.

And if you want to set android:entries programmatically with defined style.
Try this.

AppCompatSpinner spinner = findViewById(R.id.content_spinner);
CharSequence[] entries = getResources().getTextArray(R.array.shipping_tracking_carrier_names);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<>(spinner.getContext(), android.R.layout.simple_spinner_item, entries);
adapter.setDropDownViewResource(android.support.v7.appcompat.R.layout.support_simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

As in the code, using same Context with the Spinner is most important thing.

spinner.getContext()

Here is a simple approach which triggers when the video ends.

<html>
<body>

    <video id="myVideo" controls="controls">
        <source src="video.mp4" type="video/mp4">
        etc ...
    </video>

</body>
<script type='text/javascript'>

    document.getElementById('myVideo').addEventListener('ended', function(e) {

        alert('The End');

    })

</script>
</html> 

In the 'EventListener' line substitute the word 'ended' with 'pause' or 'play' to capture those events as well.

    string fileAndPath = @"c:\webserver\public\myCompany\configs\promo.xml";

    string currentDirectory = Path.GetDirectoryName(fileAndPath);

    string fullPathOnly = Path.GetFullPath(currentDirectory);

currentDirectory: c:\webserver\public\myCompany\configs

fullPathOnly: c:\webserver\public\myCompany\configs

The solution is pretty easy... Searched for it for a while and it turns out that you just have to edit 2 config-files:

• /usr/my.cnf
• /etc/mysql/my.cnf

in both files you'll have to add:

[mysqld]
...
sql_mode=NO_ENGINE_SUBSTITUTION

At least, that's what's working for 5.6.24-2+deb.sury.org~precise+2

For VS2017 you will need to add the "Microsoft Visual Studio 2017 Installer Projects" VS extension. This will give you additional Visual Studio Installer project templates. https://marketplace.visualstudio.com/items?itemName=VisualStudioProductTeam.MicrosoftVisualStudio2017InstallerProjects#overview

To install the windows service you can add a new setup wizard type project and follow the steps from Kelsey's answer https://stackoverflow.com/a/9021107/1040040

Your part:

$result = mysql_connect("localhost", "******", "*****") or die ("Could not save image name

Error: " . mysql_error());

mysql_select_db("project") or die("Could not select database");
mysql_query("INSERT into dbProfiles (photo) VALUES('".$_FILES['filep']['name']."')");
if($result) { echo "Image name saved into database

";

Doesn't make much sense, your connection shouldn't be named $result but that is a naming issue not a coding one.

What is a coding issue is if($result), your saying if you can connect to the database regardless of the insert query failing or succeeding you will output "Image saved into database".

Try adding do

$realresult = mysql_query("INSERT into dbProfiles (photo) VALUES('".$_FILES['filep']['name']."')");

and change the if($result) to $realresult

I suspect your query is failing, perhaps you have additional columns or something?

Try copy/pasting your query, replacing the ".$_FILES['filep']['name']." with test and running it in your query browser and see if it goes in.

Also worth noting you can use 'em' as well as 'px' - blogs and text based sites do it because then the browser makes layout decisions more relative to the text content.

On Wordpress twentysixteen I wanted my tagline to display on mobiles as well as desktops, so I put this in my child theme style.css

@media screen and (max-width:59em){
    p.site-description {
        display:    block;
    }
}

Type info variables to list "All global and static variable names".

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).

What if your server goes down at 4:59AM and comes back at 5:01AM? I think it will just skip the run. I would recommend persistent scheduler like Quartz, that would store its schedule data somewhere. Then it will see that this run hasn't been performed yet and will do it at 5:01AM.

If we have:

enum Gender
{
    M = 0,
    F = 1,
    U = 2
}

and

enum Gender2
{
    Male = 0,
    Female = 1,
    Unknown = 2
}

We can safely do

var gender = Gender.M;
var gender2   = (Gender2)(int)gender;

Or even

var enumOfGender2Type = (Gender2)0;

If you want to cover the case where an enum on the right side of the '=' sign has more values than the enum on the left side - you will have to write your own method/dictionary to cover that as others suggested.

You seem to be confusing asynchronous IO with asynchronous functions. node.js uses asynchronous non-blocking IO because non blocking IO is better. The best way to understand it is to go watch some videos by ryan dahl.

How do I write asynchronous functions for Node?

Just write normal functions, the only difference is that they are not executed immediately but passed around as callbacks.

How should I implement error event handling correctly

Generally API's give you a callback with an err as the first argument. For example

database.query('something', function(err, result) {
  if (err) handle(err);
  doSomething(result);
});

Is a common pattern.

Another common pattern is on('error'). For example

process.on('uncaughtException', function (err) {
  console.log('Caught exception: ' + err);
});

Edit:

var async_function = function(val, callback){
    process.nextTick(function(){
        callback(val);
    });
};

The above function when called as

async_function(42, function(val) {
  console.log(val)
});
console.log(43);

Will print 42 to the console asynchronously. In particular process.nextTick fires after the current eventloop callstack is empty. That call stack is empty after async_function and console.log(43) have run. So we print 43 followed by 42.

You should probably do some reading on the event loop.

Explanation and working solution here: Howto: div with onclick inside another div with onclick javascript

by executing this script in your inner click handler:

 if (!e) var e = window.event;
 e.cancelBubble = true;
 if (e.stopPropagation) e.stopPropagation();

Disabling the alert message is not a way to solve the problem. Despite the PHP core is continue to work it makes a dangerous assumptions and actions.

Never ignore the error where PHP should make an assumptions of something!!!!

If the class organized as a singleton you can always use function getInstance() and then use getData()

Likse:

$classObj = MyClass::getInstance();
$classObj->getData();

If the class is not a singleton, use

 $classObj = new MyClass();
 $classObj->getData();

In addition to options suggested by others I can recommend the fmt library which implements string formatting similar to str.format in Python and String.Format in C#. Here's an example:

std::string a = "test";
std::string b = "text.txt";
std::string c = "text1.txt";
std::string result = fmt::format("{0} {1} > {2}", a, b, c);

Disclaimer: I'm the author of this library.

after reading previous examples I came up with this:

protected static $nonce_length = 32;

public static function getNonce()
{
    $chars = array();
    for ($i = 0; $i < 10; $i++)
        $chars = array_merge($chars, range(0, 9), range('A', 'Z'));
    shuffle($chars);
    $start = mt_rand(0, count($chars) - self::$nonce_length);
    return substr(join('', $chars), $start, self::$nonce_length);
}

I duplicate 10 times the array[0-9,A-Z] and shuffle the elements, after I get a random start point for substr() to be more 'creative' :) you can add [a-z] and other elements to array, duplicate more or less, be more creative than me

A MySQL MyISAM table is the combination of three files:

• The FRM file is the table definition.
• The MYD file is where the actual data is stored.
• The MYI file is where the indexes created on the table are stored.

You should be able to restore by copying them in your database folder (In linux, the default location is /var/lib/mysql/)

You should do it while the server is not running.

You can give your canvas the ff CSS properties:

#myCanvas
{
    display: block;
    margin: 0 auto;
}

Use Notepad ++ and use the option to Convert the file to UNIX format. That should solve this problem.

you may also like this

var Grp = Model.GroupBy(item => item.Order.Customer)
      .Select(group => new 
        { 
             Customer = Model.First().Customer, 
             CustomerId= group.Key,  
             Orders= group.ToList() 
       })
      .ToList();

Old question but this is a rather simple task that can be solved properly with core JS... without the Class abstraction of ES6. In fact as far as i can tell, the Class abstraction do not even solve this problem.

We can do this job both with the good old constructor function or even better with Object.create(). Lets go with the constructor first. This will essentially be a similar solution to georgebrock's answer which is criticised because all restaurants created by the Restaurant constructor will have the same private methods. I will try to overcome that limitation.

function restaurantFactory(name,menu){

  function Restaurant(name){
    this.name = name;
  }

  function prototypeFactory(menu){
    // This is a private function
    function calculateBill(item){
      return menu[item] || 0;
    }
    // This is the prototype to be
    return { constructor: Restaurant
           , askBill    : function(...items){
                            var cost = items.reduce((total,item) => total + calculateBill(item) ,0)
                            return "Thank you for dining at " + this.name + ". Total is: " + cost + "\n"
                          }
           , callWaiter : function(){
                            return "I have just called the waiter at " + this.name + "\n";
                          }
           }
  }

  Restaurant.prototype = prototypeFactory(menu);

  return new Restaurant(name,menu);
}

var menu = { water: 1
           , coke : 2
           , beer : 3
           , beef : 15
           , rice : 2
           },
    name = "Silver Scooop",
    rest = restaurantFactory(name,menu);

console.log(rest.callWaiter());
console.log(rest.askBill("beer", "beef"));

Now obviously we can not access menu from outside but we may easily rename the name property of a restaurant.

This can also be done with Object.create() in which case we skip the constructor function and simply do like var rest = Object.create(prototypeFactory(menu)) and add the name property to the rest object afterwards like rest.name = name.

I had a similar problem with the SP call returning an error that an expected parameter was not included. My code was as follows.
Stored Procedure:

@Result int OUTPUT

And C#:

            SqlParameter result = cmd.Parameters.Add(new SqlParameter("@Result", DbType.Int32));
            result.Direction = ParameterDirection.ReturnValue;

In troubleshooting, I realized that the stored procedure was ACTUALLY looking for a direction of "InputOutput" so the following change fixed the problem.

            r

Result.Direction = ParameterDirection.InputOutput;

I would like to update on this, because in .NET Core multi-dimensional arrays are faster than jagged arrays. I ran the tests from John Leidegren and these are the results on .NET Core 2.0 preview 2. I increased the dimension value to make any possible influences from background apps less visible.

I looked into disassemblies and this is what I found

jagged[i][j][k] = i * j * k; needed 34 instructions to execute

multi[i, j, k] = i * j * k; needed 11 instructions to execute

single[i * dim * dim + j * dim + k] = i * j * k; needed 23 instructions to execute

I wasn't able to identify why single-dimensional arrays were still faster than multi-dimensional but my guess is that it has to do with some optimalization made on the CPU

Imagine that we have 3 buttons for example

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked 
            // Yes we will handle click here but which button clicked??? We don't know

        }
    };

}

So what we will do?

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked
            // Yes we will handle click here but which button clicked??? We don't know

            // So we will make
            switch (v.getId() /*to get clicked view id**/) {
                case R.id.corky:

                    // do something when the corky is clicked

                    break;
                case R.id.corky2:

                    // do something when the corky2 is clicked

                    break;
                case R.id.corky3:

                    // do something when the corky3 is clicked

                    break;
                default:
                    break;
            }
        }
    };

}

Or we can do this:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky is clicked
            }
        });
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky2 is clicked
            }
        });
        button3.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky3 is clicked
            }
        });

    }

}

Or we can implement View.OnClickListener and i think it's the best way:

public class MainActivity extends ActionBarActivity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        // do something when the button is clicked
        // Yes we will handle click here but which button clicked??? We don't know

        // So we will make
        switch (v.getId() /*to get clicked view id**/) {
            case R.id.corky:

                // do something when the corky is clicked

                break;
            case R.id.corky2:

                // do something when the corky2 is clicked

                break;
            case R.id.corky3:

                // do something when the corky3 is clicked

                break;
            default:
                break;
        }
    }
}

Finally there is no real differences here Just "Way better than the other"

Another deprecated (thanks to @daylight) option, and the easiest for me (this is what I'm using for SpokenToday.info):

The Google Feed API without using JQuery and with only 2 steps:

1. Import the library:

   <script type="text/javascript" src="https://www.google.com/jsapi"></script>
   <script type="text/javascript">google.load("feeds", "1");</script>
   

2. Find/Load feeds (documentation):

   var feed = new google.feeds.Feed('http://www.google.com/trends/hottrends/atom/feed?pn=p1');
   feed.load(function (data) {
       // Parse data depending on the specified response format, default is JSON.
       console.dir(data);
   });
   

3. To parse data, check documentation about the response format.

What I found worked was checking the "Use the 64 bit version of IIS Express for Web Sites and Projects" option under the Projects and Solutions => Web Projects section under the Tools=>Options menu.

The nice thing about iterator is that later on if you wanted to switch your vector to a another STD container. Then the forloop will still work.

Why not add a variable for the element's Id and make it a reusable function?

function SelectElement(selectElementId, valueToSelect)
{    
    var element = document.getElementById(selectElementId);
    element.value = valueToSelect;
}

I tried almost all the posted solutions and nothing worked for me. I use Mojave OS (10.14.6) and what finally worked for me (after removing and re-installing Xcode and CLTs and SDK headers):

1. Install Clang v8 from https://cran.r-project.org/bin/macosx/tools/
2. Modify the following lines from ~/.R/Makevars file

CC=/usr/local/opt/llvm/bin/clang -fopenmp
CXX=/usr/local/opt/llvm/bin/clang++

with

CC=/usr/local/clang8/bin/clang -fopenmp
CXX=/usr/local/clang8/bin/clang++

Now R packages that rely on C compilers install successfully

While the template approach is clever for various reasons, it is important to remember the lifecycle of the lambda and the captured variables. If any form of a lambda pointer is is going to be used and the lambda is not a downward continuation, then only a copying [=] lambda should used. I.e., even then, capturing a pointer to a variable on the stack is UNSAFE if the lifetime of those captured pointers (stack unwind) is shorter than the lifetime of the lambda.

A simpler solution for capturing a lambda as a pointer is:

auto pLamdba = new std::function<...fn-sig...>([=](...fn-sig...){...});

e.g., new std::function<void()>([=]() -> void {...}

Just remember to later delete pLamdba so ensure that you don't leak the lambda memory. Secret to realize here is that lambdas can capture lambdas (ask yourself how that works) and also that in order for std::function to work generically the lambda implementation needs to contain sufficient internal information to provide access to the size of the lambda (and captured) data (which is why the delete should work [running destructors of captured types]).

I would do it this way:

try {
  txtProt = (EditText) findViewById(R.id.Protein); // Same
  p = txtProt.getText().toString(); // Same
  protein = Double.parseDouble(p); // Make use of autoboxing.  It's also easier to read.
} catch (NumberFormatException e) {
  // p did not contain a valid double
}

EDIT: "the program force closes immediately without leaving any info in the logcat"

I don't know bout not leaving information in the logcat output, but a force-close generally means there's an uncaught exception - like a NumberFormatException.

Yes - according to the pandas.read_csv documentation:

Note: A fast-path exists for iso8601-formatted dates.

So if your csv has a column named datetime and the dates looks like 2013-01-01T01:01 for example, running this will make pandas (I'm on v0.19.2) pick up the date and time automatically:

df = pd.read_csv('test.csv', parse_dates=['datetime'])

Note that you need to explicitly pass parse_dates, it doesn't work without.

Verify with:

df.dtypes

You should see the datatype of the column is datetime64[ns]

* "For example, say you'd declared a List at the beginning of a method which grew in size to be very large, but was only required until half-way through the method. You could at this point set the List reference to null to allow the garbage collector to potentially reclaim this object before the method completes (and the reference falls out of scope anyway)." *

This is correct, but this solution may not be generalizable. While setting a List object reference to null -will- make memory available for garbage collection, this is only true for a List object of primitive types. If the List object instead contains reference types, setting the List object = null will not dereference -any- of the reference types contained -in- the list. In this case, setting the List object = null will orphan the contained reference types whose objects will not be available for garbage collection unless the garbage collection algorithm is smart enough to determine that the objects have been orphaned.

Try to disable ModSecurity from your cPanel. Log into your cPanel. Find the category "Security". There you can find ModSecurity link.Click on it and disable it for the domain you are facing the 403 error.

Some 403 errors can be solved by this method too. Go to the wordpress dashboard, settings>permalink and just click save.

Hope this helped. :)

You are creating three lists, instead of using one (you don't use the return value of DirSearch(d)). You can use a list as a parameter to save the state:

static void Main(string[] args)
{
  var list = new List<string>();
  DirSearch(list, ".");

  foreach (var file in list)
  {
    Console.WriteLine(file);
  }
}

public static void DirSearch(List<string> files, string startDirectory)
{
  try
  {
    foreach (string file in Directory.GetFiles(startDirectory, "*.*"))
    {
      string extension = Path.GetExtension(file);

      if (extension != null)
      {
        files.Add(file);
      }
    }

    foreach (string directory in Directory.GetDirectories(startDirectory))
    {
      DirSearch(files, directory);
    }
  }
  catch (System.Exception e)
  {
    Console.WriteLine(e.Message);
  }
}

I found the solution to this. There is a temporary tablespace called TEMP which is used internally by database for operations like distinct, joins,etc. Since my query(which has 4 joins) fetches almost 50 million records the TEMP tablespace does not have that much space to occupy all data. Hence the query fails even though my tablespace has free space.So, after increasing the size of TEMP tablespace the issue was resolved. Hope this helps someone with the same issue. Thanks :)

There is a very easy way:

echo "your header" > headerFile.txt
cat yourFile >> headerFile.txt

You only return a value if the current element is a string. Perhaps assigning an empty string otherwise will suffice:

var arr = ['a','b',1];
var results = arr.map(function(item){
    return (typeof item ==='string') ? item : '';  
});

Of course, if you want to filter any non-string elements, you shouldn't use map(). Rather, you should look into using the filter() function.

an existing folder will FAIL with FileExists

Function FileExists(strFileName)
' Check if a file exists - returns True or False

use instead or in addition:

Function FolderExists(strFolderPath)
' Check if a path exists

memcpy expects the first two arguments to be void*.

Try: memcpy( (void*)&RTCclk, (void*)&RTCclkBuffert, sizeof(RTCclk) );

P.S. although not necessary, convention dictates the brackets for the sizeof operator. You can get away with a lot in C that leaves code impossible to maintain, so following convention is the mark of a good (employable) C programmer.

This works fine for me on OS X Lion.

This should make life much easier. You can simply use Response.RedirectWithData(...) method in your web application easily.

Imports System.Web
Imports System.Runtime.CompilerServices

Module WebExtensions

    <Extension()> _
    Public Sub RedirectWithData(ByRef aThis As HttpResponse, ByVal aDestination As String, _
                                ByVal aData As NameValueCollection)
        aThis.Clear()
        Dim sb As StringBuilder = New StringBuilder()

        sb.Append("<html>")
        sb.AppendFormat("<body onload='document.forms[""form""].submit()'>")
        sb.AppendFormat("<form name='form' action='{0}' method='post'>", aDestination)

        For Each key As String In aData
            sb.AppendFormat("<input type='hidden' name='{0}' value='{1}' />", key, aData(key))
        Next

        sb.Append("</form>")
        sb.Append("</body>")
        sb.Append("</html>")

        aThis.Write(sb.ToString())

        aThis.End()
    End Sub

End Module

I think using script command might help. Something like,

1. script -c bash -qf fifo_pid

2. Using bash features to set after parsing.

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

edit: Reading the faq a bit longer I like the idea of the << >> operator overloading and adding as a friend of those classes, however I am not sure how this doesn't break encapsulation

How would it break encapsulation?

You break encapsulation when you allow unrestricted access to a data member. Consider the following classes:

class c1 {
public:
  int x;
};

class c2 {
public:
  int foo();
private:
  int x;
};

class c3 {
  friend int foo();
private:
  int x;
};

c1 is obviously not encapsulated. Anyone can read and modify x in it. We have no way to enforce any kind of access control.

c2 is obviously encapsulated. There is no public access to x. All you can do is call the foo function, which performs some meaningful operation on the class.

c3? Is that less encapsulated? Does it allow unrestricted access to x? Does it allow unknown functions access?

No. It allows precisely one function to access the private members of the class. Just like c2 did. And just like c2, the one function which has access is not "some random, unknown function", but "the function listed in the class definition". Just like c2, we can see, just by looking at the class definitions, a complete list of who has access.

So how exactly is this less encapsulated? The same amount of code has access to the private members of the class. And everyone who has access is listed in the class definition.

friend does not break encapsulation. It makes some Java people programmers feel uncomfortable, because when they say "OOP", they actually mean "Java". When they say "Encapsulation", they don't mean "private members must be protected from arbitrary accesses", but "a Java class where the only functions able to access private members, are class members", even though this is complete nonsense for several reasons.

First, as already shown, it is too restricting. There's no reason why friend methods shouldn't be allowed to do the same.

Second, it is not restrictive enough. Consider a fourth class:

class c4 {
public:
  int getx();
  void setx(int x);
private:
  int x;
};

This, according to aforesaid Java mentality, is perfectly encapsulated. And yet, it allows absolutely anyone to read and modify x. How does that even make sense? (hint: It doesn't)

Bottom line: Encapsulation is about being able to control which functions can access private members. It is not about precisely where the definitions of these functions are located.
