Here is a solution based on the powerful but poorly documented logging.config.dictConfig method. Instead of sending every log message to stdout, it sends messages with log level ERROR and higher to stderr and everything else to stdout. This can be useful if other parts of the system are listening to stderr or stdout.

import logging
import logging.config
import sys

class _ExcludeErrorsFilter(logging.Filter):
    def filter(self, record):
        """Only returns log messages with log level below ERROR (numeric value: 40)."""
        return record.levelno < 40


config = {
    'version': 1,
    'filters': {
        'exclude_errors': {
            '()': _ExcludeErrorsFilter
        }
    },
    'formatters': {
        # Modify log message format here or replace with your custom formatter class
        'my_formatter': {
            'format': '(%(process)d) %(asctime)s %(name)s (line %(lineno)s) | %(levelname)s %(message)s'
        }
    },
    'handlers': {
        'console_stderr': {
            # Sends log messages with log level ERROR or higher to stderr
            'class': 'logging.StreamHandler',
            'level': 'ERROR',
            'formatter': 'my_formatter',
            'stream': sys.stderr
        },
        'console_stdout': {
            # Sends log messages with log level lower than ERROR to stdout
            'class': 'logging.StreamHandler',
            'level': 'DEBUG',
            'formatter': 'my_formatter',
            'filters': ['exclude_errors'],
            'stream': sys.stdout
        },
        'file': {
            # Sends all log messages to a file
            'class': 'logging.FileHandler',
            'level': 'DEBUG',
            'formatter': 'my_formatter',
            'filename': 'my.log',
            'encoding': 'utf8'
        }
    },
    'root': {
        # In general, this should be kept at 'NOTSET'.
        # Otherwise it would interfere with the log levels set for each handler.
        'level': 'NOTSET',
        'handlers': ['console_stderr', 'console_stdout', 'file']
    },
}

logging.config.dictConfig(config)

var_dump(debug_backtrace());

Does that do what you want?

Use a trap!

tempfiles=( )
cleanup() {
  rm -f "${tempfiles[@]}"
}
trap cleanup 0

error() {
  local parent_lineno="$1"
  local message="$2"
  local code="${3:-1}"
  if [[ -n "$message" ]] ; then
    echo "Error on or near line ${parent_lineno}: ${message}; exiting with status ${code}"
  else
    echo "Error on or near line ${parent_lineno}; exiting with status ${code}"
  fi
  exit "${code}"
}
trap 'error ${LINENO}' ERR

...then, whenever you create a temporary file:

temp_foo="$(mktemp -t foobar.XXXXXX)"
tempfiles+=( "$temp_foo" )

and $temp_foo will be deleted on exit, and the current line number will be printed. (set -e will likewise give you exit-on-error behavior, though it comes with serious caveats and weakens code's predictability and portability).

You can either let the trap call error for you (in which case it uses the default exit code of 1 and no message) or call it yourself and provide explicit values; for instance:

error ${LINENO} "the foobar failed" 2

will exit with status 2, and give an explicit message.

Just another information... Had that problem today on a Windows 2012 R2 x64 TS system where the application was started from a unc/network path. The issue occured for one application for all terminal server users. Executing the application locally worked without problems. After a reboot it started working again - the SEHException's thrown had been Constructor init and TargetInvocationException

Check that the version of php you're running matches your codebase. For example, your local environment may be running php 5.4 (and things run fine) and maybe you're testing your code on a new machine that has php 5.3 installed. If you are using 5.4 syntax such as [] for array() then you'll get the situation you described above.

Edit: note that this answer is 3+ years old. For newer versions of apache, please see the answer by sp00n. Leaving this answer for users of older versions of apache.

For older version apache:

For debugging mod_rewrite issues, you'll want to use RewriteLogLevel and RewriteLog:

RewriteLogLevel 3
RewriteLog "/usr/local/var/apache/logs/rewrite.log"

A segementation fault is an internal error in php (or, less likely, apache). Oftentimes, the segmentation fault is caused by one of the newer and lesser-tested php modules such as imagemagick or subversion.

Try disabling all non-essential modules (in php.ini), and then re-enabling them one-by-one until the error occurs. You may also want to update php and apache.

If that doesn't help, you should report a php bug.

Simply create an empty file .eslintignore in your project root the type the path to the file you want it to be ignore.

git remote manpage is pretty straightforward:

Use

Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream

Then do:    
$ git remote add upstream https://github.com/Foo/repos.git

or just update the URL directly:

$ git remote set-url upstream https://github.com/Foo/repos.git

or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see

https://code.google.com/p/git-core/source/detail?spec=svne17dba8fe15028425acd6a4ebebf1b8e9377d3c6&r=e17dba8fe15028425acd6a4ebebf1b8e9377d3c6

Log message

remote: prefer subcommand name 'remove' to 'rm'

All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

Splits the string in text on any consecutive runs of whitespace.

words = text.split()      

Split the string in text on delimiter: ",".

words = text.split(",")   

The words variable will be a list and contain the words from text split on the delimiter.

If you did not define the port number and you want to know on which port it is running.

let http = require('http');
let _http = http.createServer((req, res) => {
res.writeHead(200);
res.end('Hello..!')
}).listen();
console.log(_http.address().port);

FYI, every time it will run in a different port.

With SemaphoreSlim you can achieve parallelism control.

var bag = new ConcurrentBag<object>();
var maxParallel = 20;
var throttler = new SemaphoreSlim(initialCount: maxParallel);
var tasks = myCollection.Select(async item =>
{
  try
  {
     await throttler.WaitAsync();
     var response = await GetData(item);
     bag.Add(response);
  }
  finally
  {
     throttler.Release();
  }
});
await Task.WhenAll(tasks);
var count = bag.Count;

Got this problem to, and finaly, I build myself a short solution. You just have to ellipsize manually the line you want, your maxLine attribute will cut your text.

This example cut your text for 3 lines max

        final TextView title = (TextView)findViewById(R.id.text);
        title.setText("A really long text");
        ViewTreeObserver vto = title.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {
                ViewTreeObserver obs = title.getViewTreeObserver();
                obs.removeGlobalOnLayoutListener(this);
                if(title.getLineCount() > 3){
                    Log.d("","Line["+title.getLineCount()+"]"+title.getText());
                    int lineEndIndex = title.getLayout().getLineEnd(2);
                    String text = title.getText().subSequence(0, lineEndIndex-3)+"...";
                    title.setText(text);
                    Log.d("","NewText:"+text);
                }

            }
        });

if you're using es6 template literals are an option...

string.replace(new RegExp(`ReGeX${testVar}ReGeX`), "replacement")

A bit of an older thread, but I have to agree with Redu above because splice definitely has a bit of a confusing interface. And the response given by cdbajorin that "it only returns an empty array when the second parameter is 0. If it's greater than 0, it returns the items removed from the array" is, while accurate, proving the point. The function's intent is to splice or as said earlier by Jakob Keller, "to join or connect, also to change. You have an established array that you are now changing which would involve adding or removing elements...." Given that, the return value of the elements, if any, that were removed is awkward at best. And I 100% agree that this method could have been better suited to chaining if it had returned what seems natural, a new array with the spliced elements added. Then you could do things like ["19", "17"].splice(1,0,"18").join("...") or whatever you like with the returned array. The fact that it returns what was removed is just kinda nonsense IMHO. If the intention of the method was to "cut out a set of elements" and that was it's only intent, maybe. It seems like if I don't know what I'm cutting out already though, I probably have little reason to cut those elements out, doesn't it? It would be better if it behaved like concat, map, reduce, slice, etc where a new array is made from the existing array rather than mutating the existing array. Those are all chainable, and that IS a significant issue. It's rather common to chain array manipulation. Seems like the language needs to go one or the other direction and try to stick to it as much as possible. Javascript being functional and less declarative, it just seems like a strange deviation from the norm.

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

Whenever possible, I set the field visibility as package-protected so it can be accessed from the test class. I document that using Guava's @VisibleForTesting annotation (in case the next guy wonders why it's not private). This way I don't have to rely on the string name of the field and everything stays type-safe.

I know it goes against standard encapsulation practices we were taught in school. But as soon as there is some agreement in the team to go this way, I found it the most pragmatic solution.

I figured out this workaround:

>>> p = subprocess.Popen(['grep','f'],stdout=subprocess.PIPE,stdin=subprocess.PIPE)
>>> p.stdin.write(b'one\ntwo\nthree\nfour\nfive\nsix\n') #expects a bytes type object
>>> p.communicate()[0]
'four\nfive\n'
>>> p.stdin.close()

Is there a better one?

It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

Try to use limit in your query. It's because of full disk as said by @Monsters X.

I have also faced this problem and solved by limit in query, because the thousands of records were there. Now working good :)

If jQuery is okay, you can use find(). It's basically equivalent to the way you are doing it right now.

$('#note').find('#textid');

You can also use jQuery selectors to basically achieve the same thing:

$('#note #textid');

Using these methods to get something that already has an ID is kind of strange, but I'm supplying these assuming it's not really how you plan on using it.

On a side note, you should know ID's should be unique in your webpage. If you plan on having multiple elements with the same "ID" consider using a specific class name.

Update 2020.03.10

It's a breeze to use native JS for this:

document.querySelector('#note #textid');

If you want to first find #note then #textid you have to check the first querySelector result. If it fails to match, chaining is no longer possible :(

var parent = document.querySelector('#note');
var child = parent ? parent.querySelector('#textid') : null;

Add this to html:

<svg id="mySVG" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"/>

Try this function and adapt for you program:

var svgNS = "http://www.w3.org/2000/svg";  

function createCircle()
{
    var myCircle = document.createElementNS(svgNS,"circle"); //to create a circle. for rectangle use "rectangle"
    myCircle.setAttributeNS(null,"id","mycircle");
    myCircle.setAttributeNS(null,"cx",100);
    myCircle.setAttributeNS(null,"cy",100);
    myCircle.setAttributeNS(null,"r",50);
    myCircle.setAttributeNS(null,"fill","black");
    myCircle.setAttributeNS(null,"stroke","none");

    document.getElementById("mySVG").appendChild(myCircle);
}     

You can use the localeCompare() method.

string_a.localeCompare(string_b);

/* Expected Returns:

 0:  exact match

-1:  string_a < string_b

 1:  string_a > string_b

 */

For me the problem was the execution of clone via sudo.

If you clone to a directory where you have user permission ( /home/user/git) it will work fine.

(Explanation: Running a command as superuser will not work with the same public key as running a command as user. Therefore Github refused the connection.)

This solution requires a SSH key already to be set up: https://help.github.com/articles/generating-ssh-keys

You probably had using namespace std; before in your code you did in class. That explicitly tells the precompiler to look for the symbols in std, which means you don't need to std::. Though it is good practice to std::cout instead of cout so you explicitly invoke std::cout every time. That way if you are using another library that redefines cout, you still have the std::cout behavior instead of some other custom behavior.

function isDate(dateStr) {
  return !isNaN(new Date(dateStr).getDate());
}

• This will work on any browser since it does not rely on "Invalid Date" check.
• This will work with legacy code before ES6.
• This will work without any library.
• This will work regardless of any date format.
• This does not rely on Date.parse which fails the purpose when values like "Spiderman 22" are in date string.
• This does not ask us to write any RegEx.

I'd suggest using the stopPropagation() method as shown in the modified fiddle:

Fiddle

$('body').click(function() {
    $(".popup").hide();
});

$('.popup').click(function(e) {
    e.stopPropagation();
});

That way you can hide the popup when you click on the body, without having to add an extra if, and when you click on the popup, the event doesn't bubble up to the body by going through the popup.

This method works for both Windows and Linux:

#include <stdio.h>
#include <string>
#ifdef _WIN32
#include <direct.h>
#define GetCurrentDir _getcwd
#elif __linux__
#include <unistd.h>
#define GetCurrentDir getcwd
#endif

std::string GetCurrentWorkingDir() 
{
    char buff[FILENAME_MAX];
    GetCurrentDir(buff, FILENAME_MAX);
    std::string current_working_dir(buff);
    return current_working_dir;
}

The Answer from Steve Sheldon fixed the problem for me, however, as I am scripting certificate permissions with out a gui, I needed a scriptable solution. I struggled to find where my private key was stored . The private key was not in -C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys , eventually I found that it was actually in C:\ProgramData\Microsoft\Crypto\Keys. Below I describe how I found that out:

I tried FindPrivateKey but it could not find the private key, and using powershell the $cert.privatekey.cspkeycontainerinfo.uniquekeycontainername was null/empty.

Luckily, certutil -store my listed the certificate and gave me the details I needed to script the solution.

================ Certificate 1 ================ Serial Number: 162f1b54fe78c7c8fa9df09 Issuer: CN=*.internal.xxxxxxx.net NotBefore: 23/08/2019 14:04 NotAfter: 23/02/2020 14:24 Subject: CN=*.xxxxxxxnet Signature matches Public Key Root Certificate: Subject matches Issuer Cert Hash(sha1): xxxxa5f0e9f0ac8b7dd634xx Key Container = {407EC7EF-8701-42BF-993F-CDEF8328DD} Unique container name: 8787033f8ccb5836115b87acb_ca96c65a-4b42-a145-eee62128a ##* ^-- filename for private key*## Provider = Microsoft Software Key Storage Provider Private key is NOT plain text exportable Encryption test passed CertUtil: -store command completed successfully.

I then scanned c\ProgramData\Microsoft\Crypto\ folder and found the file 8787033f8ccb5836115b87acb_ca96c65a-4b42-a145-eee62128a in C:\ProgramData\Microsoft\Crypto\Keys .

Giving my service account read access this file fixed the issues for me

As of PowerShell 5.1 there cmdlet New-LocalUser which could create local user account.

Example of usage:

Create a user account

New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword

or Create a user account that has a password

$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."

or Create a user account that is connected to a Microsoft account

New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account."

You could loop through the list and keep the tuple in a variable and then you can see both values from the same variable...

num=(0, 0)
for item in tuplelist:
  if item[1]>num[1]:
    num=item #num has the whole tuple with the highest y value and its x value

try

Sub save()
ActiveWorkbook.SaveAS Filename:="C:\-docs\cmat\Desktop\New folder\" & Range("C5").Text & chr(32) & Range("C8").Text &".xls", FileFormat:= _
  xlNormal, Password:="", WriteResPassword:="", ReadOnlyRecommended:=False _
 , CreateBackup:=False
End Sub

If you want to save the workbook with the macros use the below code

Sub save()
ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _
    "\Desktop\" & Range("C5").Text & Chr(32) & Range("C8").Text & ".xlsm", FileFormat:= _
    xlOpenXMLWorkbookMacroEnabled, Password:=vbNullString, WriteResPassword:=vbNullString, _
    ReadOnlyRecommended:=False, CreateBackup:=False
End Sub

if you want to save workbook with no macros and no pop-up use this

Sub save()
    Application.DisplayAlerts = False
    ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _
    "\Desktop\" & Range("C5").Text & Chr(32) & Range("C8").Text & ".xls", _
    FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
    Application.DisplayAlerts = True
End Sub

That's simple. You can set option to display only week days in toLocaleDateString() to get the names. For example:

(new Date()).toLocaleDateString('en-US',{ weekday: 'long'}) will return only the day of the week. And (new Date()).toLocaleDateString('en-US',{ month: 'long'}) will return only the month of the year.

This could be because your CSV file has embedded single or double quotes. If your CSV file is tab-delimited try opening it as:

Since this question is quite old and AngularJS had had time to evolve since then, this can now be easily achieved using:

<li ng-repeat="record in records" ng-bind="record + ($last ? '' : ', ')"></li>.

Note that I'm using ngBind instead of interpolation {{ }} as it's much more performant: ngBind will only run when the passed value does actually change. The brackets {{ }}, on the other hand, will be dirty checked and refreshed in every $digest, even if it's not necessary. Source: here, here and here.

On a final note, all of the solutions here work and are valid to this day. I'm really found to those which involve CSS as this is more of a presentation issue.

If the condition isn't satisfied, an AssertionError will be thrown.

Assertions have to be enabled, though; otherwise the assert expression does nothing. See:

http://java.sun.com/j2se/1.5.0/docs/guide/language/assert.html#enable-disable

You can also get this error when you have an infinite loop. Make sure that you don't have any unending, recursive self references.

First, convert the base 64 string to an Image, then use the Image.Save method.

To convert from base 64 string to Image:

 public Image Base64ToImage(string base64String)
 {
    // Convert base 64 string to byte[]
    byte[] imageBytes = Convert.FromBase64String(base64String);
    // Convert byte[] to Image
    using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
    {
        Image image = Image.FromStream(ms, true);
        return image;
    }
 }

To convert from Image to base 64 string:

public string ImageToBase64(Image image,System.Drawing.Imaging.ImageFormat format)
{
  using (MemoryStream ms = new MemoryStream())
  {
    // Convert Image to byte[]
    image.Save(ms, format);
    byte[] imageBytes = ms.ToArray();

    // Convert byte[] to base 64 string
    string base64String = Convert.ToBase64String(imageBytes);
    return base64String;
  }
}

Finally, you can easily to call Image.Save(filePath); to save the image.

Sadly even with the likes of CSS 3 we still do not have the likes of :first-word :last-word etc using pure CSS. Thankfully there's almost a JavaScript nowadays for everything which brings me to my recommendation. Using nthEverything and jQuery you can expand from the traditional Pseudo elements.

Currently the valid Pseudos are:

• :first-child
• :first-of-type
• :only-child
• :last-child
• :last-of-type
• :only-of-type
• :nth-child
• :nth-of-type
• :nth-last-child
• :nth-last-of-type

And using nth Everything we can expand this to:

• ::first-letter
• ::first-line
• ::first-word
• ::last-letter
• ::last-line
• ::last-word
• ::nth-letter
• ::nth-line
• ::nth-word
• ::nth-last-letter
• ::nth-last-line
• ::nth-last-word

Assuming that the items in your CheckedListBox are strings:

  for (int i = 0; i < checkedListBox1.Items.Count; i++)
  {
    if ((string)checkedListBox1.Items[i] == value)
    {
      checkedListBox1.SetItemChecked(i, true);
    }
  }

Or

  int index = checkedListBox1.Items.IndexOf(value);

  if (index >= 0)
  {
    checkedListBox1.SetItemChecked(index, true);
  }

you can use arraylist object from collections class

using System.Collections;

static void Main()
{
  ArrayList arr = new ArrayList();
}

when you want to add elements you can use

arr.Add();

I'm using this instead of add leading and trailing margin constraints to the layoutMarginsGuide:

UILayoutGuide *safe = self.view.safeAreaLayoutGuide;
yourView.translatesAutoresizingMaskIntoConstraints = NO;
[NSLayoutConstraint activateConstraints:@[
                                           [safe.trailingAnchor constraintEqualToAnchor:yourView.trailingAnchor],
                                           [yourView.leadingAnchor constraintEqualToAnchor:safe.leadingAnchor],
                                           [yourView.topAnchor constraintEqualToAnchor:safe.topAnchor],
                                           [safe.bottomAnchor constraintEqualToAnchor:yourView.bottomAnchor]
                                          ]];

Please also check the option for lower version of ios 11 from Krunal's answer.

There is no such flag, and having one runs against the Unix philosophy of having each tool perform just one function and perform it well. Spawning compiler processes is conceptually the job of the build system. What you are probably looking for is the -j (jobs) flag to GNU make, a la

make -j4

Or you can use pmake or similar parallel make systems.

There is a crop() method:

w, h = yourImage.size
yourImage.crop((0, 30, w, h-30)).save(...)

Note that not all of these methods will return the same value. In some cases, they can return the same value, but be careful, their purposes are different:

Application.StartupPath

returns the StartupPath parameter (can be set when run the application)

System.IO.Directory.GetCurrentDirectory()

returns the current directory, which may or may not be the folder where the application is located. The same goes for Environment.CurrentDirectory. In case you are using this in a DLL file, it will return the path of where the process is running (this is especially true in ASP.NET).

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

Accessing the fields directly is not really good style in java. I would suggest creating getter and setter methods for the fields of your bean and then using then Introspector and BeanInfo classes from the java.beans package.

MyBean bean = new MyBean();
BeanInfo beanInfo = Introspector.getBeanInfo(MyBean.class);
for (PropertyDescriptor propertyDesc : beanInfo.getPropertyDescriptors()) {
    String propertyName = propertyDesc.getName();
    Object value = propertyDesc.getReadMethod().invoke(bean);
}

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

This is what worked for me:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://maps.google.co.in/maps?q=" + yourAddress));
if (intent.resolveActivity(getPackageManager()) != null) {
   startActivity(intent);
}

Try this

'''
This is a multiline
comment. I can type here whatever I want.
'''

Python does have a multiline string/comment syntax in the sense that unless used as docstrings, multiline strings generate no bytecode -- just like #-prepended comments. In effect, it acts exactly like a comment.

On the other hand, if you say this behavior must be documented in the official docs to be a true comment syntax, then yes, you would be right to say it is not guaranteed as part of the language specification.

In any case your editor should also be able to easily comment-out a selected region (by placing a # in front of each line individually). If not, switch to an editor that does.

Programming in Python without certain text editing features can be a painful experience. Finding the right editor (and knowing how to use it) can make a big difference in how the Python programming experience is perceived.

Not only should the editor be able to comment-out selected regions, it should also be able to shift blocks of code to the left and right easily, and should automatically place the cursor at the current indentation level when you press Enter. Code folding can also be useful.

Use the LIMIT clause:

/* rows x- y numbers */
SELECT * FROM tbl LIMIT x,y;

refer : http://dev.mysql.com/doc/refman/5.0/en/select.html

function _arrayBufferToBase64( buffer ) {
    var binary = '';
    var bytes = new Uint8Array( buffer );
    var len = bytes.byteLength;
    for (var i = 0; i < len; i++) {
        binary += String.fromCharCode( bytes[ i ] );
    }
    return window.btoa( binary );
}

but, non-native implementations are faster e.g. https://gist.github.com/958841 see http://jsperf.com/encoding-xhr-image-data/6

I think, this example suggests a small nuance on how the partitioning works and how group by works. My example is from Oracle 12, if my example happens to be a compiling bug.

I tried :

SELECT t.data_key
,      SUM ( CASE when t.state = 'A' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_a_rows
,      SUM ( CASE when t.state = 'B' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_b_rows
,      SUM ( CASE when t.state = 'C' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_c_rows
,      COUNT (1) total_rows
from mytable t
group by t.data_key  ---- This does not compile as the compiler feels that t.state isn't in the group by and doesn't recognize the aggregation I'm looking for

This however works as expected :

SELECT distinct t.data_key
,      SUM ( CASE when t.state = 'A' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_a_rows
,      SUM ( CASE when t.state = 'B' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_b_rows
,      SUM ( CASE when t.state = 'C' THEN 1 ELSE 0 END) 
OVER   (PARTITION BY t.data_key) count_c_rows
,      COUNT (1) total_rows
from mytable t;

Producing the number of elements in each state based on the external key "data_key". So, if, data_key = 'APPLE' had 3 rows with state 'A', 2 rows with state 'B', a row with state 'C', the corresponding row for 'APPLE' would be 'APPLE', 3, 2, 1, 6.

When using the window[objname], please make sure the objname is global variables. Otherwise, will work sometime, and fail sometimes. window[objname].value.

The problem is that for json.load you should pass a file like object with a read function defined. So either you use json.load(response) or json.loads(response.read()).

free -h | awk '/Mem\:/ { print $2 }' 

This will provide you with the total memory in your system in human readable format and automatically scale to the appropriate unit ( e.g. bytes, KB, MB, or GB).

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

Scheme doesn't have algebraic data types or pattern matching but it's certainly a functional language. Annoying things about Python from a functional programming perspective:

1. Crippled Lambdas. Since Lambdas can only contain an expression, and you can't do everything as easily in an expression context, this means that the functions you can define "on the fly" are limited.

2. Ifs are statements, not expressions. This means, among other things, you can't have a lambda with an If inside it. (This is fixed by ternaries in Python 2.5, but it looks ugly.)

3. Guido threatens to remove map, filter, and reduce every once in a while

On the other hand, python has lexical closures, Lambdas, and list comprehensions (which are really a "functional" concept whether or not Guido admits it). I do plenty of "functional-style" programming in Python, but I'd hardly say it's ideal.

It's not really something you need jQuery to do. There is a very simple plain old javascript method for doing this:

window.open('http://www.google.com','GoogleWindow', 'width=800, height=600');

That's it.

The first arg is the url, the second is the name of the window, this should be specified because IE will throw a fit about trying to use window.opener later if there was no window name specified (just a little FYI), and the last two params are width/height.

EDIT: Full specification can be found in the link mmmshuddup provided.

Click here Code Project! Its Code project example. Its working to me

Instead of applying the col-md-* classes to each td in the row you can create a colgroup and apply the classes to the col tag.

    <table class="table table-striped">
        <colgroup>
            <col class="col-md-4">
            <col class="col-md-7">
        </colgroup>
        <tbody>
        <tr>
            <td>Title</td>
            <td>Long Value</td>
        </tr>
        </tbody>
    </table>

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Here's some documentation on how to use Jconsole.

You could create a unique index with a coalesce on the MenuId:

CREATE UNIQUE INDEX
Favorites_UniqueFavorite ON Favorites
(UserId, COALESCE(MenuId, '00000000-0000-0000-0000-000000000000'), RecipeId);

You'd just need to pick a UUID for the COALESCE that will never occur in "real life". You'd probably never see a zero UUID in real life but you could add a CHECK constraint if you are paranoid (and since they really are out to get you...):

alter table Favorites
add constraint check
(MenuId <> '00000000-0000-0000-0000-000000000000')

I tried:

import os
os.path.abspath(os.path.join(os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))), os.pardir))

Try the DrawEllipse method instead.

You'll want to use the specified market protocol:

final String appPackageName = "com.example"; // Can also use getPackageName(), as below
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));

Keep in mind, this will crash on any device that does not have the Market installed (the emulator, for example). Hence, I would suggest something like:

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}

While using getPackageName() from Context or subclass thereof for consistency (thanks @cprcrack!). You can find more on Market Intents here: link.

I added the following aliases to my .gitconfig file. This allows me to delete branches with or without specifying the branch name. Branch name is defaulted to the current branch if no argument is passed in.

[alias]
    branch-name = rev-parse --abbrev-ref HEAD     

    rm-remote-branch = !"f() { branch=${1-$(git branch-name)}; git push origin :$branch; }; f"
    rm-local-branch = !"f() { branch=${1-$(git branch-name)}; git checkout master; git branch -d $branch; }; f"
    rm-branch-fully = !"f() { branch=${1-$(git branch-name)}; git rm-local-branch $branch; git rm-remote-branch $branch; }; f"

You cannot trust g++ 4.6.3 here with 64 bit integers on a 32 bit intel platform. a/b is computed by a call to divdi3 and a%b is computed by a call to moddi3. I can even come up with an example that computes a/b and a-b*(a/b) with these calls. So I use c=a/b and a-b*c.

The div method gives a call to a function which computes the div structure, but a function call seems inefficient on platforms which have hardware support for the integral type (i.e. 64 bit integers on 64 bit intel/amd platforms).

slice works just fine in IE and other browsers, it's part of the specification and it's the most efficient method too:

alert("xxx_456".slice(-3));
//-> 456

You can't multiply string and float.instead of you try as below.it works fine

totalAmount = salesAmount * float(salesTax)

I solved the same problem. I've just added JSTL-1.2.jar to /apache-tomcat-x.x.x/lib and set scope to provided in maven pom.xml:

 <dependency>
     <groupId>jstl</groupId>
     <artifactId>jstl</artifactId>

IDs must be unique in your document, meaning that you shouldn't do this:

<input type="checkbox" name="chk[]" id="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" id="chk[]" value="Bananas" />

Instead, drop the ID, and then select them by name, or by a containing element:

<fieldset id="checkArray">
    <input type="checkbox" name="chk[]" value="Apples" />

    <input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>

And now the jQuery:

var atLeastOneIsChecked = $('#checkArray:checkbox:checked').length > 0;
//there should be no space between identifier and selector

// or, without the container:

var atLeastOneIsChecked = $('input[name="chk[]"]:checked').length > 0;

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

You can try the Boost Tokenizer library, in particular the Escaped List Separator

Also, you can use gem install --local path_to_gem/filename.gem

This will skip the usual gem repository scan that happens when you leave off --local.

You can find other magic with gem install --help.

Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.

The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback) function from fs module:

var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
  if (err) {
    // append failed
  } else {
    // done
  }
})

But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options]) function instead:

var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
  flags: 'a' // 'a' means appending (old data will be preserved)
})

logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again

Node will keep appending new data to your file every time you'll call .write, until your application will be closed, or until you'll manually close the stream calling .end:

logger.end() // close string

I had the same problem after upgrading to Ubuntu 14.10. I found this link which describes the steps to be followed in order to apply the patch. It takes a while since you have to start all over again: downloading, building, installing... but it worked for me! Sorry I'm not an expert and I can't provide further details.

Here are the steps described in the link above:

If you want to patch and build mysql-workbench yourself, get the source from for 6.2.3. From the directory you downloaded it to, do:

wget 'http://dev.mysql.com/get/Downloads/MySQLGUITools/mysql-workbench-community-6.2.3-src.tar.gz'

tar xvf mysql-workbench-community-6.2.3-src.tar.gz && cd mysql-workbench-community-6.2.3-src

wget -O patch-glib.diff 'http://bugs.mysql.com/file.php?id=21874&bug_id=74147'

patch -p0 < patch-glib.diff

sudo apt-get build-dep mysql-workbench

sudo apt-get install libgdal-dev

cd build

cmake .. -DBUILD_CONFIG=mysql_release

make

sudo make install

Hope this can be helpful.

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

You can use a conditional expression:

x if x is not None else some_value

Example:

In [22]: x = None

In [23]: print x if x is not None else "foo"
foo

In [24]: x = "bar"

In [25]: print x if x is not None else "foo"
bar

I am assuming from context and the tags you used that you are writing a .NET C# app. In this case, you can subscribe to the text changed event, and validate each key stroke.

private void textBox1_TextChanged(object sender, EventArgs e)
{
    if (System.Text.RegularExpressions.Regex.IsMatch(textBox1.Text, "[^0-9]"))
    {
        MessageBox.Show("Please enter only numbers.");
        textBox1.Text = textBox1.Text.Remove(textBox1.Text.Length - 1);
    }
}

You can write like that. This is for whenever you change context path you don't need to modify your jsp file.

<link rel="stylesheet" href="${pageContext.request.contextPath}/css/styles.css" />

location.href = "Pagename.html";

As a supplement to the question and above answers there is also an important difference between plt.subplots() and plt.subplot(), notice the missing 's' at the end.

One can use plt.subplots() to make all their subplots at once and it returns the figure and axes (plural of axis) of the subplots as a tuple. A figure can be understood as a canvas where you paint your sketch.

# create a subplot with 2 rows and 1 columns
fig, ax = plt.subplots(2,1)

Whereas, you can use plt.subplot() if you want to add the subplots separately. It returns only the axis of one subplot.

fig = plt.figure() # create the canvas for plotting
ax1 = plt.subplot(2,1,1) 
# (2,1,1) indicates total number of rows, columns, and figure number respectively
ax2 = plt.subplot(2,1,2)

However, plt.subplots() is preferred because it gives you easier options to directly customize your whole figure

# for example, sharing x-axis, y-axis for all subplots can be specified at once
fig, ax = plt.subplots(2,2, sharex=True, sharey=True)

whereas, with plt.subplot(), one will have to specify individually for each axis which can become cumbersome.

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

I presume you are talking about filling zeros of some existing mat? How about this? :)

mat *= 0;

Unfortunately most of add-ons and browser extensions are just showing the values to you but they don't let you to edit scope variables or run angular functions. If you wanna change the $scope variables in browser console (in all browsers) then you can use jquery. If you load jQuery before AngularJS, angular.element can be passed a jQuery selector. So you could inspect the scope of a controller with

angular.element('[ng-controller="name of your controller"]').scope()

Example: You need to change value of $scope variable and see the result in the browser then just type in the browser console:

angular.element('[ng-controller="mycontroller"]').scope().var1 = "New Value";
angular.element('[ng-controller="mycontroller"]').scope().$apply();

You can see the changes in your browser immediately. The reason we used $apply() is: any scope variable updated from outside angular context won't update it binding, You need to run digest cycle after updating values of scope using scope.$apply() .

For observing a $scope variable value, you just need to call that variable.

Example: You wanna see the value of $scope.var1 in the web console in Chrome or Firefox just type:

angular.element('[ng-controller="mycontroller"]').scope().var1;

The result will be shown in the console immediately.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

I was struggling with this too. My changes weren't being reflected in phpInfo. It wasn't until I stopped my servers and then restarted them again that my changes actually took effect.

Here is a quick code snippet comparing two functions. The first is traditional recursion for finding the factorial of a given number. The second uses tail recursion.

Very simple and intuitive to understand.

An easy way to tell if a recursive function is a tail recursive is if it returns a concrete value in the base case. Meaning that it doesn't return 1 or true or anything like that. It will more than likely return some variant of one of the method parameters.

Another way is to tell is if the recursive call is free of any addition, arithmetic, modification, etc... Meaning its nothing but a pure recursive call.

public static int factorial(int mynumber) {
    if (mynumber == 1) {
        return 1;
    } else {            
        return mynumber * factorial(--mynumber);
    }
}

public static int tail_factorial(int mynumber, int sofar) {
    if (mynumber == 1) {
        return sofar;
    } else {
        return tail_factorial(--mynumber, sofar * mynumber);
    }
}

You can only use - on the numeric entries, so you can use decreasing and negate the ones you want in increasing order:

DT[order(x,-v,decreasing=TRUE),]
      x y v
 [1,] c 1 7
 [2,] c 3 8
 [3,] c 6 9
 [4,] b 1 1
 [5,] b 3 2
 [6,] b 6 3
 [7,] a 1 4
 [8,] a 3 5
 [9,] a 6 6

In Visual Studio vesrion 1.34.0 View -> Toggle Render Whitespace

Try with:

order by lower(column_name) asc;

How about Freebase? I think they have an API available, too.

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

I have tried like this

git rm --cached -r * -f

And it is working for me.

You can specify your own debug keystore if you wish. This solution also gives you the ability to store your keys outside of the project directory as well as enjoy automation in the signing process. Yes you can go to File -> Project Structure and assign signing keystores and passwords in the Signing tab but that will put plaintext entries into your gradle.build file which means your secrets might be disclosed (especially in repository commits). With this solution you get the control of using your own keystore and the magic of automation during debug and release builds.

1) Create a gradle.properties (if you don't already have one).

The location for this file depends on your OS:

   /home/<username>/.gradle/ (Linux)
   /Users/<username>/.gradle/ (Mac)
   C:\Users\<username>\.gradle (Windows)

2) Add an entry pointing to yourprojectname.properties file. (example for Windows)

yourprojectname.properties=c:\\Users\\<username>\\signing\\yourprojectname.properties

3) Create yourprojectname.properties file in the location you specified in Step 2 with the following information:

keystore=C:\\path\\to\\keystore\\yourapps.keystore
keystore.password=your_secret_password

4) Modify your gradle.build file to point to yourprojectname.properties file to use the variables.

if(project.hasProperty("yourprojectname.properties")
        && new File(project.property("yourprojectname.properties")).exists()) {

    Properties props = new Properties()
    props.load(new FileInputStream(file(project.property("yourprojectname.properties"))))

    android {
        signingConfigs {
            release {
                keyAlias 'release'
                keyPassword props['keystore.password']
                storeFile file(props['keystore'])
                storePassword props['keystore.password']
            }
            debug {
                keyAlias 'debug'
                keyPassword props['keystore.password']
                storeFile file(props['keystore'])
                storePassword props['keystore.password']
            }
        }
        compileSdkVersion 19
        buildToolsVersion "20.0.0"
        defaultConfig {
            applicationId "your.project.app"
            minSdkVersion 16
            targetSdkVersion 17
        }
        buildTypes {
            release {
            }
        }
    }

}

dependencies {
    ...
}

5) Enjoy! Now all of your keys will be outside of the root of the directory and yet you still have the joys of automation for each build.

If you get an error in your gradle.build file about the "props" variable it's because you are not executing the "android {}" block inside the very first if condition where the props variable gets assigned so just move the entire android{ ... } section into the condition in which the props variable is assigned then try again.

I pieced these steps together from the information found here and here.

Gives you the list of files with full path:

  Sys.glob(file.path(file_dir, "*.dbf")) ## file_dir = file containing directory

Change *.cs to .cs in the excludefileslist.txt

You can use rsplit

string.rsplit('delimeter',1)[1]

To get the string from reverse.

Try prepending the doublequote with a backslash in your expresssion:

sed 's/\"//g' [file name]

This nodejs-based answer will use encodeURIComponent on stdin:

uriencode_stdin() {
    node -p 'encodeURIComponent(require("fs").readFileSync(0))'
}

echo -n $'hello\nwörld' | uriencode_stdin
hello%0Aw%C3%B6rld

There are several ways. One way is to use save() to save the exact object. e.g. for data frame foo:

save(foo,file="data.Rda")

Then load it with:

load("data.Rda")

You could also use write.table() or something like that to save the table in plain text, or dput() to obtain R code to reproduce the table.

I had same problem, but I think I have simple solution(code is from my RoR app): Extract industry ids from yahoo.finance.sectors and add it to db:

    select = "select * from yahoo.finance.sectors"
    generate_query select
    @data.each do |data|
      data["industry"].each do |ind|
        unless ind.kind_of?(Array)
          unless ind["id"].nil?
            id = ind["id"].to_i
            if id > 0
              Industry.where(id: id).first_or_create(name: ind["name"]).update_attribute(:name, ind["name"])
            end
          end
        end
      end
    end

Extract all comanies with their symbols with industry ids:

    ids = Industry.all.map{|ind| "'#{ind.id.to_s}'" }.join(",")
    select = "select * from yahoo.finance.industry where id in"
    generate_query select, ids
    @data.each do |ts|
      unless ts.kind_of?(Array) || ts["company"].nil?
        if ts["company"].count == 2 && ts["company"].first[0] == "name"
          t = ts["company"]
          Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])
        else
          ts["company"].each do |t|
            Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])
          end
        end
      end
    end
  end

Connection hellper:

def generate_query(select, ids = nil)
    if params[:form] || params[:action] == "sectors" || params[:controller] == "tickets"
      if params[:action] == "sectors" || params[:controller] == "tickets"

Sorry for mess, but this is first testing version for my project and I needed it very fast. There are some helpers variabels and other things for my app, sorry for it. But I have question: Have many symbols do you have? I have 5500.

In short you have to do like this

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "https://maven.fabric.io/public" }
}

Detail:

You need to specify each maven URL in its own curly braces. Here is what I got working with skeleton dependencies for the web services project I’m going to build up:

apply plugin: 'java'

sourceCompatibility = 1.7
version = '1.0'

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "http://maven.restlet.org" }
  mavenCentral()
}

dependencies {
  compile group:'org.restlet.jee', name:'org.restlet', version:'2.1.1'
  compile group:'org.restlet.jee', name:'org.restlet.ext.servlet',version.1.1'
  compile group:'org.springframework', name:'spring-web', version:'3.2.1.RELEASE'
  compile group:'org.slf4j', name:'slf4j-api', version:'1.7.2'
  compile group:'ch.qos.logback', name:'logback-core', version:'1.0.9'
  testCompile group:'junit', name:'junit', version:'4.11'
}

After t.thielemans' answer, I worked that just

=VLOOKUP(A1, B:C, 2, FALSE) 

works fine and does what I wanted, except that it returns #N/A for non-matches; so it is suitable for the case where it is known that the value definitely exists in the look-up column.

Edit (based on t.thielemans' comment):

To avoid #N/A for non-matches, do:

=IFERROR(VLOOKUP(A1, B:C, 2, FALSE), "No Match")

Would you be happy to make "my file.xls" active if it didn't affect the screen? Turning off screen updating is the way to achieve this, it also has performance improvements (significant if you are doing looping while switching around worksheets / workbooks).

The command to do this is:

    Application.ScreenUpdating = False

Don't forget to turn it back to True when your macros is finished.

I did the following...

1. place your css file in the app/assets/stylesheets folder.
2. Add the stylesheet link <%= stylesheet_link_tag "filename" %> in your default layouts file (most likely application.html.erb)

I recommend this over using your public folder. You can also reference the stylesheet inline, such as in your index page.

Use Linq-XML,

XDocument doc = XDocument.Load(file);

var result = from ele in doc.Descendants("sog")
              select new
              {
                 field1 = (string)ele.Element("field1")
              };
 foreach (var t in result)
  {
      HttpContext.Current.Response.Write(t.field1);
  }

OR : Get the node list of <sog> tag.

 XmlDocument xmlDoc = new XmlDocument();
 xmlDoc.Load(myXML);
 XmlNodeList parentNode = xmlDoc.GetElementsByTagName("sog");
 foreach (XmlNode childrenNode in parentNode)
  {
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("field1").InnerText);
   }

1 - You can set a timeout in your application :

var client = new YourServiceReference.YourServiceClass();
client.Timeout = 60; // or -1 for infinite

It is in milliseconds.

2 - Also you can increase timeout value in httpruntime tag in web/app.config :

<configuration>
     <system.web>
          <httpRuntime executionTimeout="<<**seconds**>>" />
          ...
     </system.web>
</configuration>

For ASP.NET applications, the Timeout property value should always be less than the executionTimeout attribute of the httpRuntime element in Machine.config. The default value of executionTimeout is 90 seconds. This property determines the time ASP.NET continues to process the request before it returns a timed out error. The value of executionTimeout should be the proxy Timeout, plus processing time for the page, plus buffer time for queues. -- Source

Access 2010 has both stored procedures, and also has table triggers. And, both features are available even when you not using a server (so, in 100% file based mode).

If you using SQL Server with Access, then of course the stored procedures are built using SQL Server and not Access.

For Access 2010, you open up the table (non-design view), and then choose the table tab. You see options there to create store procedures and table triggers.

For example:

Note that the stored procedure language is its own flavor just like Oracle or SQL Server (T-SQL). Here is example code to update an inventory of fruits as a result of an update in the fruit order table

Keep in mind these are true engine-level table triggers. In fact if you open up that table with VB6, VB.NET, FoxPro or even modify the table on a computer WITHOUT Access having been installed, the procedural code and the trigger at the table level will execute. So, this is a new feature of the data engine jet (now called ACE) for Access 2010. As noted, this is procedural code that runs, not just a single statement.

Works for me, has nothing to do with PHP 5.3. Just like many such options it cannot be overriden via ini_set() when safe_mode is enabled. Check your updated php.ini (and better yet: change the memory_limit there too).

You can use CSS3 filters. They are relatively easy to implement, though are only supported on webkit at the minute. Samsung Galaxy 2's browser should support though, as I think that's a webkit browser?

Instead of sudo, try

su - username command

In my experience, sudo is not always available on RHEL systems, but su is, because su is part of the coreutils package whereas sudo is in the sudo package.

I've worked around the inability to put a border on the select in IE7 (IE8 in compatibility mode)

By giving it a border as wel as a padding, it looks like something....

Not everything, but it's start...

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

My ngninx logs are located here:

/usr/local/var/log/nginx/*

You can also check your nginx.conf to see if you have any directives dumping to custom log.

run nginx -t to locate your nginx.conf.

# in ngingx.conf
error_log  /usr/local/var/log/nginx/error.log;
error_log  /usr/local/var/log/nginx/error.log  notice;
error_log  /usr/local/var/log/nginx/error.log  info;

Nginx is usually set up in /usr/local or /etc/. The server could be configured to dump logs to /var/log as well.

If you have an alternate location for your nginx install and all else fails, you could use the find command to locate your file of choice.

find /usr/ -path "*/nginx/*" -type f -name '*.log', where /usr/ is the folder you wish to start searching from.

Preprocess your input CSV to replace blank entries with \N.

Attempt at a regex: s/,,/,\n,/g and s/,$/,\N/g

Good luck.

Simple example with good coding practices and covering all cases :

        File f = new File(Constants.RFC_INDEX_LOCAL_NAME);
        if (f.exists()) {
            throw new FileAlreadyExistsException(f.getAbsolutePath());
        } else {
            try {
                URL u = new URL(url);
                FileUtils.copyURLToFile(u, f);
            } catch (MalformedURLException ex) {
                Logger.getLogger(RfcFetcher.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
                Logger.getLogger(RfcFetcher.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

You can always play around with htmlHelpers and build some stuff

    public static IHtmlContent BtnWithAction(this IHtmlHelper htmlHelper, string id, string text, string css="", string action="", string controller="")
    {
        try
        {
            string str = $"<button id=\"{id}\" class=\"{css}\" type=\"button\" ###>{text}</button>";
            if (!string.IsNullOrEmpty(action) && !string.IsNullOrEmpty(controller))
            {                    
                string url = ((TagBuilder)htmlHelper.ActionLink("dummy", action, controller)).Attributes["href"];
                var click = !string.IsNullOrEmpty(url) ? $"onclick=\"location.href='{url}'\"" : string.Empty;
                return new HtmlString(str.Replace("###", click));
            }
            return new HtmlString(str.Replace("###", string.Empty));
        }
        catch (Exception ex)
        {
            Log.Error(ex, ex.Message);
            var fkup = "<script>alert(\"assumption is the mother of all failures\")</script>";
            return new HtmlString(fkup);
        }
    }

And then on the view call it like this

@Html.BtnWithAction("btnCaretakerBack", "Back", "btn btn-primary float-right", "Index", "Caretakers")

Is not possbile!

The only way is to obfuscate javascript or minify your javascript which makes it hard for the end user to reverse engineer. however its not impossible to reverse engineer.

This TypeScript code

class A {
    private a1;
    public a2;
}

compiles to this JavaScript code

class A {
}

That's because properties in JavaScript start extisting only after they have some value. You have to assign the properties some value.

class A {
    private a1 = "";
    public a2 = "";
}

it compiles to

class A {
    constructor() {
        this.a1 = "";
        this.a2 = "";
    }
}

Still, you cannot get the properties from mere class (you can get only methods from prototype). You must create an instance. Then you get the properties by calling Object.getOwnPropertyNames().

let a = new A();
let array = return Object.getOwnPropertyNames(a);

array[0] === "a1";
array[1] === "a2";

Applied to your example

class Describer {
    static describe(instance): Array<string> {
        return Object.getOwnPropertyNames(instance);
    }
}

let a = new A();
let x = Describer.describe(a);

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);

Below code is for getting data from online server using GET method and okHTTP library for android kotlin...

Log.e("Main",response.body!!.string())

in above line !! is the thing using which you can get the json from response body

val client = OkHttpClient()
            val request: Request = Request.Builder()
                .get()
                .url("http://172.16.10.126:8789/test/path/jsonpage")
                .addHeader("", "")
                .addHeader("", "")
                .build()
            client.newCall(request).enqueue(object : Callback {
                override fun onFailure(call: Call, e: IOException) {
                    // Handle this
                    Log.e("Main","Try again latter!!!")
                }

                override fun onResponse(call: Call, response: Response) {
                    // Handle this
                    Log.e("Main",response.body!!.string())
                }
            })

For your requirement, Popen function of subprocess python module is the answer. For example,

Assuming you want all "overlapping" time periods, i.e. all that have at least one day in common.

Try to envision time periods on a straight time line and move them around before your eyes and you will see the necessary conditions.

SELECT *
FROM   tbl
WHERE  start_date <= '2012-04-12'::date
AND    end_date   >= '2012-01-01'::date;

This is sometimes faster for me than OVERLAPS - which is the other good way to do it (as @Marco already provided).

Note the subtle difference (per documentation):

OVERLAPS automatically takes the earlier value of the pair as the start. Each time period is considered to represent the half-open interval start <= time < end, unless start and end are equal in which case it represents that single time instant. This means for instance that two time periods with only an endpoint in common do not overlap.

Bold emphasis mine.

Performance

For big tables the right index can help performance (a lot).

CREATE INDEX tbl_date_inverse_idx ON tbl(start_date, end_date DESC);

Possibly with another (leading) index column if you have additional selective conditions.

Note the inverse order of the two columns. Detailed explanation:

• Optimizing queries on a range of timestamps (two columns)

Just fix css:

/* the slides */
.slick-slider {
    overflow: hidden;
}
/* the parent */
.slick-list {
    margin: 0 -9px;
}
/* item */  
.item{
    padding: 0 9px;
}

Say you're dealing with some other delimiter, such as a \t tab, instead of a \n newline.

A more general approach to delimiters is the use of getc(), which grabs one character at a time.

Note that getc() returns an int, so that we can test for equality with EOF.

Secondly, we define an array line[BUFFER_MAX_LENGTH] of type char, in order to store up to BUFFER_MAX_LENGTH-1 characters on the stack (we have to save that last character for a \0 terminator character).

Use of an array avoids the need to use malloc and free to create a character pointer of the right length on the heap.

#define BUFFER_MAX_LENGTH 1024

int main(int argc, char* argv[])
{
    FILE *file = NULL;
    char line[BUFFER_MAX_LENGTH];
    int tempChar;
    unsigned int tempCharIdx = 0U;

    if (argc == 2)
         file = fopen(argv[1], "r");
    else {
         fprintf(stderr, "error: wrong number of arguments\n"
                         "usage: %s textfile\n", argv[0]);
         return EXIT_FAILURE;
    }

    if (!file) {
         fprintf(stderr, "error: could not open textfile: %s\n", argv[1]);
         return EXIT_FAILURE;
    }

    /* get a character from the file pointer */
    while(tempChar = fgetc(file))
    {
        /* avoid buffer overflow error */
        if (tempCharIdx == BUFFER_MAX_LENGTH) {
            fprintf(stderr, "error: line is too long. increase BUFFER_MAX_LENGTH.\n");
            return EXIT_FAILURE;
        }

        /* test character value */
        if (tempChar == EOF) {
            line[tempCharIdx] = '\0';
            fprintf(stdout, "%s\n", line);
            break;
        }
        else if (tempChar == '\n') {
            line[tempCharIdx] = '\0';
            tempCharIdx = 0U;
            fprintf(stdout, "%s\n", line);
            continue;
        }
        else
            line[tempCharIdx++] = (char)tempChar;
    }

    return EXIT_SUCCESS;
}

If you must use a char *, then you can still use this code, but you strdup() the line[] array, once it is filled up with a line's worth of input. You must free this duplicated string once you're done with it, or you'll get a memory leak:

#define BUFFER_MAX_LENGTH 1024

int main(int argc, char* argv[])
{
    FILE *file = NULL;
    char line[BUFFER_MAX_LENGTH];
    int tempChar;
    unsigned int tempCharIdx = 0U;
    char *dynamicLine = NULL;

    if (argc == 2)
         file = fopen(argv[1], "r");
    else {
         fprintf(stderr, "error: wrong number of arguments\n"
                         "usage: %s textfile\n", argv[0]);
         return EXIT_FAILURE;
    }

    if (!file) {
         fprintf(stderr, "error: could not open textfile: %s\n", argv[1]);
         return EXIT_FAILURE;
    }

    while(tempChar = fgetc(file))
    {
        /* avoid buffer overflow error */
        if (tempCharIdx == BUFFER_MAX_LENGTH) {
            fprintf(stderr, "error: line is too long. increase BUFFER_MAX_LENGTH.\n");
            return EXIT_FAILURE;
        }

        /* test character value */
        if (tempChar == EOF) {
            line[tempCharIdx] = '\0';
            dynamicLine = strdup(line);
            fprintf(stdout, "%s\n", dynamicLine);
            free(dynamicLine);
            dynamicLine = NULL;
            break;
        }
        else if (tempChar == '\n') {
            line[tempCharIdx] = '\0';
            tempCharIdx = 0U;
            dynamicLine = strdup(line);
            fprintf(stdout, "%s\n", dynamicLine);
            free(dynamicLine);
            dynamicLine = NULL;
            continue;
        }
        else
            line[tempCharIdx++] = (char)tempChar;
    }

    return EXIT_SUCCESS;
}

As of maven-javadoc-plugin 3.0.0 you should have been using additionalJOption to set an additional Javadoc option, so if you would like Javadoc to disable doclint, you should add the following property.

<properties>
    ...
    <additionalJOption>-Xdoclint:none</additionalJOption>
    ...
<properties>

You should also mention the version of maven-javadoc-plugin as 3.0.0 or higher.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>3.0.0</version>

static methods don't use any instance variables of the class they are defined in. A very good explanation of the difference can be found on this page

I modified the code of william with a output comments for better understandable

   static void changeStr(String in) { 
      in = in+" changed";
      System.out.println("fun:"+in); //value changed 
    }
    static void changeStrBuf(StringBuffer in) {
      in.append(" changed");   //value changed
    }

    public static void main(String[] args) {
       StringBuffer sb = new StringBuffer("value");
       String str = "value";
       changeStrBuf(sb);
       changeStr(str);
       System.out.println("StringBuffer: "+sb); //value changed
       System.out.println("String: "+str);       // value 
    }

In above code , look at the value of str in both main() and changeStr() , even though u r changing the value of str in changeStr() it is affecting only to that function but in the main function the value is not changed , but it not in the case of StringBuffer..

In StringBuffer changed value is affected as a global..

hence String is immutable and StringBuffer is mutable...

In Simple , whatever u changed to String Object will affecting only to that function By going to String Pool. but not Changed...

When you say the first three columns, do you mean your SUM columns? If so, add ELSE 0 to your CASE statements. The SUM of a NULL value is NULL.

sum(case when c.runstatus = 'Succeeded' then 1 else 0 end) as Succeeded, 
sum(case when c.runstatus = 'Failed' then 1 else 0 end) as Failed, 
sum(case when c.runstatus = 'Cancelled' then 1 else 0 end) as Cancelled,

You can very easily create an EXE (for Windows) without using any cryptic build commands. You can do it right in Visual Studio.

1. Right click the Console App Project and select Publish.
2. A new page will open up (screen shot below)
3. Hit Configure...
4. Then change Deployment Mode to Self-contained or Framework dependent. .NET Core 3.0 introduces a Single file deployment which is a single executable.
5. Use "framework dependent" if you know the target machine has a .NET Core runtime as it will produce fewer files to install.
6. If you now view the bin folder in explorer, you will find the .exe file.
7. You will have to deploy the exe along with any supporting config and dll files.

In Kotlin List can be converted into ArrayList through passing it as a constructor parameter.

ArrayList(list)

Similar idea to the AKS algorithm which has been mentioned

public static boolean isPrime(int n) {

    if(n == 2 || n == 3) return true;
    if((n & 1 ) == 0 || n % 3 == 0) return false;
    int limit = (int)Math.sqrt(n) + 1;
    for(int i = 5, w = 2; i <= limit; i += w, w = 6 - w) {
        if(n % i == 0) return false;
        numChecks++;
    }
    return true;
}

if(!preg_match('/^[\w-]+$/', $string1)) {
   echo "String 1 not acceptable acceptable";
   // String2 acceptable
}

Putting the subquery in the WHERE clause and restricting it to n.control_number means it runs the subquery many times. This is called a correlated subquery, and it's often a performance killer.

It's better to run the subquery once, in the FROM clause, to get the max date per control number.

SELECT n.* 
FROM tblpm n 
INNER JOIN (
  SELECT control_number, MAX(date_updated) AS date_updated
  FROM tblpm GROUP BY control_number
) AS max USING (control_number, date_updated);

Generates a WHERE field IN (‘item’, ‘item’) SQL query joined with AND if appropriate,

$this->db->where_in()
ex :  $this->db->where_in('id', array('1','2','3'));

Generates a WHERE field IN (‘item’, ‘item’) SQL query joined with OR if appropriate

$this->db->or_where_in()
ex :  $this->db->where_in('id', array('1','2','3'));

#ffffff are actually 3 color components in hexadecimal notation - red ff, green ff and blue ff. You can write hexadecimal notation in Swift using 0x prefix, e.g 0xFF

To simplify the conversion, let's create an initializer that takes integer (0 - 255) values:

extension UIColor {
   convenience init(red: Int, green: Int, blue: Int) {
       assert(red >= 0 && red <= 255, "Invalid red component")
       assert(green >= 0 && green <= 255, "Invalid green component")
       assert(blue >= 0 && blue <= 255, "Invalid blue component")

       self.init(red: CGFloat(red) / 255.0, green: CGFloat(green) / 255.0, blue: CGFloat(blue) / 255.0, alpha: 1.0)
   }

   convenience init(rgb: Int) {
       self.init(
           red: (rgb >> 16) & 0xFF,
           green: (rgb >> 8) & 0xFF,
           blue: rgb & 0xFF
       )
   }
}

Usage:

let color = UIColor(red: 0xFF, green: 0xFF, blue: 0xFF)
let color2 = UIColor(rgb: 0xFFFFFF)

How to get alpha?

Depending on your use case, you can simply use the native UIColor.withAlphaComponent method, e.g.

let semitransparentBlack = UIColor(rgb: 0x000000).withAlphaComponent(0.5)

Or you can add an additional (optional) parameter to the above methods:

convenience init(red: Int, green: Int, blue: Int, a: CGFloat = 1.0) {
    self.init(
        red: CGFloat(red) / 255.0,
        green: CGFloat(green) / 255.0,
        blue: CGFloat(blue) / 255.0,
        alpha: a
    )
}

convenience init(rgb: Int, a: CGFloat = 1.0) {
    self.init(
        red: (rgb >> 16) & 0xFF,
        green: (rgb >> 8) & 0xFF,
        blue: rgb & 0xFF,
        a: a
    )
}

(we cannot name the parameter alpha because of a name collision with the existing initializer).

Called as:

let color = UIColor(red: 0xFF, green: 0xFF, blue: 0xFF, a: 0.5)
let color2 = UIColor(rgb: 0xFFFFFF, a: 0.5)

To get the alpha as an integer 0-255, we can

convenience init(red: Int, green: Int, blue: Int, a: Int = 0xFF) {
    self.init(
        red: CGFloat(red) / 255.0,
        green: CGFloat(green) / 255.0,
        blue: CGFloat(blue) / 255.0,
        alpha: CGFloat(a) / 255.0
    )
}

// let's suppose alpha is the first component (ARGB)
convenience init(argb: Int) {
    self.init(
        red: (argb >> 16) & 0xFF,
        green: (argb >> 8) & 0xFF,
        blue: argb & 0xFF,
        a: (argb >> 24) & 0xFF
    )
}

Called as

let color = UIColor(red: 0xFF, green: 0xFF, blue: 0xFF, a: 0xFF)
let color2 = UIColor(argb: 0xFFFFFFFF)

Or a combination of the previous methods. There is absolutely no need to use strings.

SwiftUI: You can use the LinearGradient struct as the first element in a ZStack. As the "bottom" of the ZStack, it will serve as the background color. AngularGradient and RadialGradient are also available.

import SwiftUI

struct ContentView: View {
    var body: some View {
        ZStack {
            LinearGradient(gradient: Gradient(colors: [.red, .blue]), startPoint: .top, endPoint: .bottom)
                .edgesIgnoringSafeArea(.all)
            // Put other content here; it will appear on top of the background gradient
        }
    }
}

Object.prototype.hasAttr = function(attr) {
    if(this.attr) {
        var _attr = this.attr(attr);
    } else {
        var _attr = this.getAttribute(attr);
    }
    return (typeof _attr !== "undefined" && _attr !== false && _attr !== null);      
};

I came a crossed this while writing my own function to do the same thing... I though I'd share in case someone else stumbles here. I added null because getAttribute() will return null if the attribute does not exist.

This method will allow you to check jQuery objects and regular javascript objects.

Change your code like this. You forget about the value inside option. Before you assign the ng-model. It must have a value. Only then it doesn't get the undefined value.

<div ng-app="MyApp1">
<div ng-controller="MyController">
    <input type="text" ng-model="feed.name" placeholder="Name" />
     <select ng-model="feed">
        <option ng-repeat="template in configs" value="template.value">{{template.name}}    
 </option>
    </select>
    </div>
 </div>

JS

 var MyApp=angular.module('MyApp1',[])
 MyApp.controller('MyController',function($scope) {  
      $scope.feed = 'config1';      
      $scope.configs = [
         {'name': 'Config 1', 'value': 'config1'},
         {'name': 'Config 2', 'value': 'config2'},
         {'name': 'Config 3', 'value': 'config3'}
      ];
 });

Alex provided the correct reason for not being able to do what you're trying to do, so +1. But you are encountering this issue because you're not quite using resolves how they're designed.

resolve takes either the string of a service or a function returning a value to be injected. Since you're doing the latter, you need to pass in an actual function:

resolve: {
  data: function (dbService) {
    return dbService.getData();
  }
}

When the framework goes to resolve data, it will inject the dbService into the function so you can freely use it. You don't need to inject into the config block at all to accomplish this.

Bon appetit!

Another way:

File test1.py:

print "test1.py"

File service.py:

import subprocess

subprocess.call("test1.py", shell=True)

The advantage to this method is that you don't have to edit an existing Python script to put all its code into a subroutine.

Documentation: Python 2, Python 3

If you plan to get first element often - you can extend QuerySet in this direction:

class FirstQuerySet(models.query.QuerySet):
    def first(self):
        return self[0]


class ManagerWithFirstQuery(models.Manager):
    def get_query_set(self):
        return FirstQuerySet(self.model)

Define model like this:

class MyModel(models.Model):
    objects = ManagerWithFirstQuery()

And use it like this:

 first_object = MyModel.objects.filter(x=100).first()

How about this solution?

The answers given so far are not ideal because they require a lot of needless work resolving merge conflicts, or they make too many assumptions which are frequently false. This is how to do it perfectly. The link is to my own site.

How to Commit to a Different Branch in git

You have uncommited changes on my_branch that you want to commit to master, without committing all the changes from my_branch.

Example

git merge master
git stash -u
git checkout master
git stash apply
git reset
git add example.js
git commit
git checkout .
git clean -f -d
git checkout my_branch
git merge master
git stash pop

Explanation

Start by merging master into your branch, since you'll have to do that eventually anyway, and now is the best time to resolve any conflicts.

The -u option (aka --include-untracked) in git stash -u prevents you from losing untracked files when you later do git clean -f -d within master.

After git checkout master it is important that you do NOT git stash pop, because you will need this stash later. If you pop the stash created in my_branch and then do git stash in master, you will cause needless merge conflicts when you later apply that stash in my_branch.

git reset unstages everything resulting from git stash apply. For example, files that have been modified in the stash but do not exist in master get staged as "deleted by us" conflicts.

git checkout . and git clean -f -d discard everything that isn't committed: all changes to tracked files, and all untracked files and directories. They are already saved in the stash and if left in master would cause needless merge conflicts when switching back to my_branch.

The last git stash pop will be based on the original my_branch, and so will not cause any merge conflicts. However, if your stash contains untracked files which you have committed to master, git will complain that it "Could not restore untracked files from stash". To resolve this conflict, delete those files from your working tree, then git stash pop, git add ., and git reset.

DevArt's OraDirect provider now supports entity framework. See http://devart.com/news/2008/directs475.html

I found the smoothest way to achieve this was using Pageant as the SSH agent and plink.

You need to have a putty session configured for the hostname that is used in your remote.

You will also need plink.exe which can be downloaded from the same site as putty.

And you need Pageant running with your key loaded. I have a shortcut to pageant in my startup folder that loads my SSH key when I log in.

When you install git-scm you can then specify it to use tortoise/plink rather than OpenSSH.

The net effect is you can open git-bash whenever you like and push/pull without being challenged for passphrases.

Same applies with putty and WinSCP sessions when pageant has your key loaded. It makes life a hell of a lot easier (and secure).

Make sure you don't have any firewalls blocking SMTP. The first time I tried to send an email, it was blocked both by Windows Firewall and McAfee - took forever to find them both.

Also if you want to save some money you don't must buy a Mac. There is other ways how to do it:

1.) You can use practically any OS to run latest MacOS in virtual machine (look at YouTube). I am using this method really long time without any problems on windows with VMWare.

2.) Hackintosh. Install MacOS to your PC. You must have compatible components, but if you have, this is the best way, because you eliminate the lags in VM... I am using this in this time. Perfect. On my laptop, but please don't tell this to Apple, because practically this is illegal

3.) If you are making simple apps with minimum UI, you can use Theos. Also with Theos you can create cydia tweaks. Only one problem: codesign. If you want to publish app on App Store you still must have MacOS, but if you want to make app in home you can use CydiaImpactor to sign the apps with Apple ID.

I used all of this ways and all is working. By my VM is best solution if you don't want to spend lot of time by installing Hackintosh.

Views are not currently supported by Entity Framework Core. See https://github.com/aspnet/EntityFramework/issues/827.

That said, you can trick EF into using a view by mapping your entity to the view as if it were a table. This approach comes with limitations. e.g. you can't use migrations, you need to manually specific a key for EF to use, and some queries may not work correctly. To get around this last part, you can write SQL queries by hand

context.Images.FromSql("SELECT * FROM dbo.ImageView")

You can navigate conditionally by this way

import { useHistory } from "react-router-dom";

function HomeButton() {
  const history = useHistory();

  function handleClick() {
    history.push("/path/some/where");
  }

  return (
    <button type="button" onClick={handleClick}>
      Go home
    </button>
  );
}

This should give you the current date minus 1 year:

select now() - interval '1 year';

Using .on() you can define your function once, and it will execute for any dynamically added elements.

for example

$('#staticDiv').on('click', 'yourSelector', function() {
  //do something
});

I use PHP to find the URL and match the page name (without the extension of .php, also I can add multiple pages that all have the same word in common like contact, contactform, etc. All will have that class added) and add a class with PHP to change the color, etc. For that you would have to save your pages with file extension .php.

Here is a demo. Change your links and pages as required. The CSS class for all the links is .tab and for the active link there is also another class of .currentpage (as is the PHP function) so that is where you will overwrite your CSS rules. You could name them whatever you like.

    $currentpage = $_SERVER['REQUEST_URI'];?>

                     echo " currentpage";

2. Run mysql_secure_installation to change new password

ref: http://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html

You want options(warn=-1). However, note that warn=0 is not the safest warning level and it should not be assumed as the current one, particularly within scripts or functions. Thus the safest way to temporary turn off warnings is:

oldw <- getOption("warn")
options(warn = -1)

[your "silenced" code]

options(warn = oldw)

You don't need to use JsonConverterAttribute, keep your model clean, also use CustomCreationConverter, the code is simpler:

public class SampleConverter : CustomCreationConverter<ISample>
{
    public override ISample Create(Type objectType)
    {
        return new Sample();
    }
}

Then:

var sz = JsonConvert.SerializeObject( sampleGroupInstance );
JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter());

Documentation: Deserialize with CustomCreationConverter

Update

The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.

In Enums.NET you'd use:

string description = ((MyEnum)value).AsString(EnumFormat.Description);

Original post

I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:

string description = Enums.GetDescription((MyEnum)value);

This:

• Ensures (with generic type constraints) that the value really is an enum value
• Avoids the boxing in your current solution
• Caches all the descriptions to avoid using reflection on every call
• Has a bunch of other methods, including the ability to parse the value from the description

I realise the core answer was just the cast from an int to MyEnum, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)

The following POSIX program will print the names of the files in the current directory:

#define _XOPEN_SOURCE 700
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main (void)
{
  DIR *dp;
  struct dirent *ep;     
  dp = opendir ("./");

  if (dp != NULL)
  {
    while (ep = readdir (dp))
      puts (ep->d_name);

    (void) closedir (dp);
  }
  else
    perror ("Couldn't open the directory");

  return 0;
}

Tested in Ubuntu 16.04.

To test for the existence of a command line paramater, use empty brackets:

IF [%1]==[] echo Value Missing

or

IF [%1] EQU [] echo Value Missing

The SS64 page on IF will help you here. Under "Does %1 exist?".

You can't set a positional parameter, so what you should do is do something like

SET MYVAR=%1

You can then re-set MYVAR based on its contents.

With PHP version 7.2 I just used nd_mysqli instead of mysqli and it worked as expected.

Steps to enable it into godaddy hosting server-

1. Login to cpanel.
2. Click on "Select PHP version".
3. As provided the snapshot of the latest configurations uncheck "mysqli" and enable "nd_mysqli".

mock.patch is a very very different critter than mock.Mock. patch replaces the class with a mock object and lets you work with the mock instance. Take a look at this snippet:

>>> class MyClass(object):
...   def __init__(self):
...     print 'Created MyClass@{0}'.format(id(self))
... 
>>> def create_instance():
...   return MyClass()
... 
>>> x = create_instance()
Created MyClass@4299548304
>>> 
>>> @mock.patch('__main__.MyClass')
... def create_instance2(MyClass):
...   MyClass.return_value = 'foo'
...   return create_instance()
... 
>>> i = create_instance2()
>>> i
'foo'
>>> def create_instance():
...   print MyClass
...   return MyClass()
...
>>> create_instance2()
<mock.Mock object at 0x100505d90>
'foo'
>>> create_instance()
<class '__main__.MyClass'>
Created MyClass@4300234128
<__main__.MyClass object at 0x100505d90>

patch replaces MyClass in a way that allows you to control the usage of the class in functions that you call. Once you patch a class, references to the class are completely replaced by the mock instance.

mock.patch is usually used when you are testing something that creates a new instance of a class inside of the test. mock.Mock instances are clearer and are preferred. If your self.sut.something method created an instance of MyClass instead of receiving an instance as a parameter, then mock.patch would be appropriate here.

And u can also use that select statement as left join query... Example :

... left join (select OrderNO,
   PartCode,
   Quantity from (select OrderNO,
         PartCode,
         Quantity,
         row_number() over(partition by OrderNO order by DateEntered desc) as rn
  from YourTable) as T where rn = 1 ) RESULT on ....

Hope this help someone that search for this :)

All you want is the below regex:

^\d+$

I think what you are being asked to do (or perhaps asking yourself?) is take a character value which matches the name of a column in a particular dataframe (possibly also given as a character). There are two tricks here. Most people learn to extract columns with the "$" operator and that won't work inside a function if the function is passed a character vecor. If the function is also supposed to accept character argument then you will need to use the get function as well:

 df1 <- data.frame(a=1:10, b=11:20)
 mean_col <- function( dfrm, col ) mean( get(dfrm)[[ col ]] )
 mean_col("df1", "b")
 # [1] 15.5

There is sort of a semantic boundary between ordinary objects like character vectors and language objects like the names of objects. The get function is one of the functions that lets you "promote" character values to language level evaluation. And the "$" function will NOT evaluate its argument in a function, so you need to use"[[". "$" only is useful at the console level and needs to be completely avoided in functions.

I have found that the VT char is used in pptx text boxes at the end of each line shown in the box in oder to adjust the text to the size of the box. It seems to be automatically generated by powerpoint (not introduced by the user) in order to move the text to the next line and fix the complete text block to the text box. In the example below, in the position of §:

"This is a text §
inside a text box"

If you are using C# you should use Environment.NewLine, which accordingly to MSDN it is:

A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

Here's a simple little utility class that you can use to convert local date times from zone to zone, including a utility method directly to convert a local date time from the current zone to UTC (with main method so you can run it and see the results of a simple test):

import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;

public final class DateTimeUtil {
    private DateTimeUtil() {
        super();
    }

    public static void main(final String... args) {
        final LocalDateTime now = LocalDateTime.now();
        final LocalDateTime utc = DateTimeUtil.toUtc(now);

        System.out.println("Now: " + now);
        System.out.println("UTC: " + utc);
    }

    public static LocalDateTime toZone(final LocalDateTime time, final ZoneId fromZone, final ZoneId toZone) {
        final ZonedDateTime zonedtime = time.atZone(fromZone);
        final ZonedDateTime converted = zonedtime.withZoneSameInstant(toZone);
        return converted.toLocalDateTime();
    }

    public static LocalDateTime toZone(final LocalDateTime time, final ZoneId toZone) {
        return DateTimeUtil.toZone(time, ZoneId.systemDefault(), toZone);
    }

    public static LocalDateTime toUtc(final LocalDateTime time, final ZoneId fromZone) {
        return DateTimeUtil.toZone(time, fromZone, ZoneOffset.UTC);
    }

    public static LocalDateTime toUtc(final LocalDateTime time) {
        return DateTimeUtil.toUtc(time, ZoneId.systemDefault());
    }
}

I did it that way and I like it better, but it can be optimized, right?

// Obtengo los botones y la caja de contenido
var home = document.getElementById("home");
var about = document.getElementById("about");
var service = document.getElementById("service");
var contact = document.getElementById("contact");
var content = document.querySelector("section");

function botonPress(e){
  console.log(e.getAttribute("id"));
  var screen = e.getAttribute("id");
  switch(screen){
    case "home":
      // cambiar fondo
      content.style.backgroundColor = 'black';
      break;
    case "about":
      // cambiar fondo
      content.style.backgroundColor = 'blue';
      break;
    case "service":
      // cambiar fondo
      content.style.backgroundColor = 'green';
      break;
    case "contact":
      // cambiar fondo
      content.style.backgroundColor = 'red';
      break;
  }
}

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

Add this configurations in pom.xml

Update on the accepted answer:

Because of many properties becoming deprecated

(property) KeyboardEvent.which: number @deprecated

you should just rely on the key property and create the rest of the logic by yourself:

The code allows Enter, Backspace and all numbers [0-9], every other character is disallowed.

document.querySelector("input").addEventListener("keypress", (e) => {
  if (isNaN(parseInt(e.key, 10)) && e.key !== "Backspace" && e.key !== "Enter") {
      e.preventDefault();
    }
});

NOTE This will disable paste action

You can map the strings to enum values, then switch on the enum:

enum Options {
    Option_Invalid,
    Option1,
    Option2,
    //others...
};

Options resolveOption(string input);

//  ...later...

switch( resolveOption(input) )
{
    case Option1: {
        //...
        break;
    }
    case Option2: {
        //...
        break;
    }
    // handles Option_Invalid and any other missing/unmapped cases
    default: {
        //...
        break;
    }
}

Resolving the enum can be implemented as a series of if checks:

 Options resolveOption(std::string input) {
    if( input == "option1" ) return Option1;
    if( input == "option2" ) return Option2;
    //...
    return Option_Invalid;
 }

Or a map lookup:

 Options resolveOption(std::string input) {
    static const std::map<std::string, Option> optionStrings {
        { "option1", Option1 },
        { "option2", Option2 },
        //...
    };

    auto itr = optionStrings.find(input);
    if( itr != optionStrings.end() ) {
        return *itr;
    }
    return Option_Invalid; 
}

The problem here is that you are including commands.c in commands.h before the function prototype. Therefore, the C pre-processor inserts the content of commands.c into commands.h before the function prototype. commands.c contains the function definition. As a result, the function definition ends up before than the function declaration causing the error.

The content of commands.h after the pre-processor phase looks like this:

#ifndef COMMANDS_H_
#define COMMANDS_H_

// function definition
void f123(){

}

// function declaration
void f123();

#endif /* COMMANDS_H_ */

This is an error because you can't declare a function after its definition in C. If you swapped #include "commands.c" and the function declaration the error shouldn't happen because, now, the function prototype comes before the function declaration.

However, including a .c file is a bad practice and should be avoided. A better solution for this problem would be to include commands.h in commands.c and link the compiled version of command to the main file. For example:

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123(); // function declaration

#endif

commands.c

#include "commands.h"

void f123(){} // function definition

Search it for a long time, and finally, I found how to do it:)

The code project article Creating a Tasktray Application gives a very simple explanation and example of creating an application that only ever exists in the System Tray.

Basically change the Application.Run(new Form1()); line in Program.cs to instead start up a class that inherits from ApplicationContext, and have the constructor for that class initialize a NotifyIcon

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new MyCustomApplicationContext());
    }
}


public class MyCustomApplicationContext : ApplicationContext
{
    private NotifyIcon trayIcon;

    public MyCustomApplicationContext ()
    {
        // Initialize Tray Icon
        trayIcon = new NotifyIcon()
        {
            Icon = Resources.AppIcon,
            ContextMenu = new ContextMenu(new MenuItem[] {
                new MenuItem("Exit", Exit)
            }),
            Visible = true
        };
    }

    void Exit(object sender, EventArgs e)
    {
        // Hide tray icon, otherwise it will remain shown until user mouses over it
        trayIcon.Visible = false;

        Application.Exit();
    }
}

Quoting this link: http://steveswanson.wordpress.com/2009/04/21/exporting-and-importing-an-individual-mysql-table/

• Exporting the Table

To export the table run the following command from the command line:

mysqldump -p --user=username dbname tableName > tableName.sql

This will export the tableName to the file tableName.sql.

• Importing the Table

To import the table run the following command from the command line:

mysql -u username -p -D dbname < tableName.sql

The path to the tableName.sql needs to be prepended with the absolute path to that file. At this point the table will be imported into the DB.

CURL in PHP:

Summary:

The curl_exec command in PHP is a bridge to use curl from console. curl_exec makes it easy to quickly and easily do GET/POST requests, receive responses from other servers like JSON and download files.

Warning, Danger:

curl is evil and dangerous if used improperly because it is all about getting data from out there in the internet. Someone can get between your curl and the other server and inject a rm -rf / into your response, and then why am I dropped to a console and ls -l doesn't even work anymore? Because you mis underestimated the dangerous power of curl. Don't trust anything that comes back from curl to be safe, even if you are talking to your own servers. You could be pulling back malware to relieve fools of their wealth.

Examples:

These were done on Ubuntu 12.10

1. Basic curl from the commandline:

   el@apollo:/home/el$ curl http://i.imgur.com/4rBHtSm.gif > mycat.gif
     % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                    Dload  Upload   Total   Spent    Left  Speed
   100  492k  100  492k    0     0  1077k      0 --:--:-- --:--:-- --:--:-- 1240k
   

   Then you can open up your gif in firefox:

   firefox mycat.gif
   

   Glorious cats evolving Toxoplasma gondii to cause women to keep cats around and men likewise to keep the women around.

2. cURL example get request to hit google.com, echo to the commandline:

   This is done through the phpsh terminal:

   php> $ch = curl_init();
   
   php> curl_setopt($ch, CURLOPT_URL, 'http://www.google.com');
   
   php> curl_exec($ch);
   

   Which prints and dumps a mess of condensed html and javascript (from google) to the console.

3. cURL example put the response text into a variable:

   This is done through the phpsh terminal:

   php> $ch = curl_init();
   
   php> curl_setopt($ch, CURLOPT_URL, 'http://i.imgur.com/wtQ6yZR.gif');
   
   php> curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
   php> $contents = curl_exec($ch);
   
   php> echo $contents;
   

   The variable now contains the binary which is an animated gif of a cat, possibilities are infinite.

4. Do a curl from within a PHP file:

   Put this code in a file called myphp.php:

   <?php
     $curl_handle=curl_init();
     curl_setopt($curl_handle,CURLOPT_URL,'http://www.google.com');
     curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
     curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
     $buffer = curl_exec($curl_handle);
     curl_close($curl_handle);
     if (empty($buffer)){
         print "Nothing returned from url.<p>";
     }
     else{
         print $buffer;
     }
   ?>
   

   Then run it via commandline:

   php < myphp.php
   

   You ran myphp.php and executed those commands through the php interpreter and dumped a ton of messy html and javascript to screen.

   You can do GET and POST requests with curl, all you do is specify the parameters as defined here: Using curl to automate HTTP jobs

Reminder of danger:

Be careful dumping curl output around, if any of it gets interpreted and executed, your box is owned and your credit card info will be sold to third parties and you'll get a mysterious $900 charge from an Alabama one-man flooring company that's a front for overseas credit card fraud crime ring.

From python 3.x you can do:

print('bla bla', end='')

(which can also be used in Python 2.6 or 2.7 by putting from __future__ import print_function at the top of your script/module)

Python console progressbar example:

import time

# status generator
def range_with_status(total):
    """ iterate from 0 to total and show progress in console """
    n=0
    while n<total:
        done = '#'*(n+1)
        todo = '-'*(total-n-1)
        s = '<{0}>'.format(done+todo)
        if not todo:
            s+='\n'        
        if n>0:
            s = '\r'+s
        print(s, end='')
        yield n
        n+=1

# example for use of status generator
for i in range_with_status(10):
    time.sleep(0.1)

What I would do is comment out the Dockerfile below and including the offending line. Then you can run the container and run the docker commands by hand, and look at the logs in the usual way. E.g. if the Dockerfile is

RUN foo
RUN bar
RUN baz

and it's dying at bar I would do

RUN foo
# RUN bar
# RUN baz

Then

$ docker build -t foo .
$ docker run -it foo bash
container# bar
...grep logs...

We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.

NSDictionary from NSData

http://www.cocoanetics.com/2009/09/nsdictionary-from-nsdata/

NSDictionary to NSData

You can use NSPropertyListSerialization class for that. Have a look at its method:

+ (NSData *)dataFromPropertyList:(id)plist format:(NSPropertyListFormat)format
                              errorDescription:(NSString **)errorString

Returns an NSData object containing a given property list in a specified format.

After trying everything, my solution was removing some PNG files, build and run (ok) and adding again the PNG images. Weird!

You have to do this on the change event of the input type file this way:

$('#select_file').click(function() {
    $('#image_file').show();
    $('.btn').prop('disabled', false);
    $('#image_file').change(function() {
        var filename = $('#image_file').val();
        $('#select_file').html(filename);
    });
});?

To Calculate days between 2 given dates you can use the following code.Dates I use here are Jan 01 2016 and Dec 31 2016

var day_start = new Date("Jan 01 2016");_x000D_
var day_end = new Date("Dec 31 2016");_x000D_
var total_days = (day_end - day_start) / (1000 * 60 * 60 * 24);_x000D_
document.getElementById("demo").innerHTML = Math.round(total_days);

<h3>DAYS BETWEEN GIVEN DATES</h3>_x000D_
<p id="demo"></p>

One you convert your image to gray-scale you cannot got back. You have gone from three channel to one, when you try to go back all three numbers will be the same. So the short answer is no you cannot go back. The reason your backtorgb function this throwing that error is because it needs to be in the format:

CvtColor(input, output, CV_GRAY2BGR)

OpenCV use BGR not RGB, so if you fix the ordering it should work, though your image will still be gray.

SQL Server 2012 has a wonderful and long-awaited new DATEFROMPARTS function (which will raise an error if the date is invalid - my main objection to a DATEADD-based solution to this problem):

http://msdn.microsoft.com/en-us/library/hh213228.aspx

DATEFROMPARTS(ycolumn, mcolumn, dcolumn)

or

DATEFROMPARTS(@y, @m, @d)
