Programs & Examples On #Development process

If you need to do this as part of a script then the best way is to use Java. Assuming the bin directory is in your path (in most cases), you can use the command line:

jar xf test.zip

If Java is not on your path, reference it directly:

C:\Java\jdk1.6.0_03\bin>jar xf test.zip

Working on a project I was stuck for some time on this concept - I ended up with a similar answer to Method 1 by @GSerg that worked great. Essentially I defined two formula ranges (using a few variables) and then used the Union concept. My example is from a larger project that I'm working on but hopefully the portion of code below can help some other people who might not know how to use the Union concept in conjunction with defined ranges and variables. I didn't include the entire code because at this point it's fairly long - if anyone wants more insight feel free to let me know.

First I declared all my variables as Public

Then I defined/set each variable

Lastly I set a new variable "SelectRanges" as the Union between the two other FormulaRanges

Public r As Long
Public c As Long
Public d As Long
Public FormulaRange3 As Range
Public FormulaRange4 As Range
Public SelectRanges As Range

With Sheet8




  c = pvt.DataBodyRange.Columns.Count + 1

  d = 3

  r = .Cells(.Rows.Count, 1).End(xlUp).Row

Set FormulaRange3 = .Range(.Cells(d, c + 2), .Cells(r - 1, c + 2))
    FormulaRange3.NumberFormat = "0"
    Set FormulaRange4 = .Range(.Cells(d, c + c + 2), .Cells(r - 1, c + c + 2))
    FormulaRange4.NumberFormat = "0"
    Set SelectRanges = Union(FormulaRange3, FormulaRange4)

Of all the answers, none considered the ridiculously easy fastcgi_finish_request function, that when called, flushes all remaining output to the browser and closes the Fastcgi session and the HTTP connection, while letting the script run in the background.

An example:

<?php
header('Content-Type: application/json');
echo json_encode(['ok' => true]);
fastcgi_finish_request(); // The user is now disconnected from the script

// do stuff with received data,

Current date and time

$current_date_time = date('Y-m-d H:i:s');

15 min ago Date and time

$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));

Many answers already, but one more option

PyPSExec https://pypi.org/project/pypsexec/

It's a python clone of the famous psexec. Works without any installation on the remote windows machine.

I think you just have to walk the finally blocks:

1. Print "1".
2. finally in q print "3".
3. finally in main print "2".

You should never write code that concatenates SQL and parameters as string - this opens up your code to SQL injection which is a really serious security problem.

Use bind params - for a nice howto see here...

In JavaScript you can encode single quotes as "\x27" and double quotes as "\x22". Therefore, with this method you can, once you're inside the (double or single) quotes of a JavaScript string literal, use the \x27 \x22 with impunity without fear of any embedded quotes "breaking out" of your string.

\xXX is for chars < 127, and \uXXXX for Unicode, so armed with this knowledge you can create a robust JSEncode function for all characters that are out of the usual whitelist.

For example,

<a href="#" onclick="SelectSurveyItem('<% JSEncode(itemid) %>', '<% JSEncode(itemname) %>'); return false;">Select</a>

A sample using C# is here.

public static void Main()
{
    Console.WriteLine("Hello World " + LevenshteinDistance("Hello","World"));
    Console.WriteLine("Choice A " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE GREEN CHICKEN"));
    Console.WriteLine("Choice B " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE RED COW"));
    Console.WriteLine("Choice C " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED FOX JUMPED OVER THE BROWN COW"));
}

public static float LevenshteinDistance(string a, string b)
{
    var rowLen = a.Length;
    var colLen = b.Length;
    var maxLen = Math.Max(rowLen, colLen);

    // Step 1
    if (rowLen == 0 || colLen == 0)
    {
        return maxLen;
    }

    /// Create the two vectors
    var v0 = new int[rowLen + 1];
    var v1 = new int[rowLen + 1];

    /// Step 2
    /// Initialize the first vector
    for (var i = 1; i <= rowLen; i++)
    {
        v0[i] = i;
    }

    // Step 3
    /// For each column
    for (var j = 1; j <= colLen; j++)
    {
        /// Set the 0'th element to the column number
        v1[0] = j;

        // Step 4
        /// For each row
        for (var i = 1; i <= rowLen; i++)
        {
            // Step 5
            var cost = (a[i - 1] == b[j - 1]) ? 0 : 1;

            // Step 6
            /// Find minimum
            v1[i] = Math.Min(v0[i] + 1, Math.Min(v1[i - 1] + 1, v0[i - 1] + cost));
        }

        /// Swap the vectors
        var vTmp = v0;
        v0 = v1;
        v1 = vTmp;
    }

    // Step 7
    /// The vectors were swapped one last time at the end of the last loop,
    /// that is why the result is now in v0 rather than in v1
    return v0[rowLen];
}

The output is:

Hello World 4
Choice A 15
Choice B 6
Choice C 8

What are you trying to achieve? There is absolutely no reason to ever do what you describe, and there is likely a much better solution to the problem you're trying to solve..

The most obvious alternative to what you request is a dictionary. For example:

>>> my_data = {'var': 'something'}
>>> my_data['something_else'] = 'something'
>>> print my_data.keys()
['var', 'something_else']
>>> print my_data['var']
something

Mostly as a.. challenge, I implemented your desired output. Do not use this code, please!

#!/usr/bin/env python2.6
class NewLocals:
    """Please don't ever use this code.."""
    def __init__(self, initial_locals):
        self.prev_locals = list(initial_locals.keys())

    def show_new(self, new_locals):
        output = ", ".join(list(set(new_locals) - set(self.prev_locals)))
        self.prev_locals = list(new_locals.keys())
        return output
# Set up
eww = None
eww = NewLocals(locals())

# "Working" requested code

var = {}

print eww.show_new(locals())  # Outputs: var

something_else = 3
print eww.show_new(locals()) # Outputs: something_else

# Further testing

another_variable = 4
and_a_final_one = 5

print eww.show_new(locals()) # Outputs: another_variable, and_a_final_one

If a process has a lock on an SQLite DB and crashes, the DB stays locked permanently. That's the problem. It's not that some other process has a lock.

When implementing the onClickListener, you can use v.getContext.startActivity.

btn.setOnClickListener(new OnClickListener() {                  
    @Override
    public void onClick(View v) {
        v.getContext().startActivity(PUT_YOUR_INTENT_HERE);
    }
});

The exact answer to the question is: yes, you can use an arbitrary value for the boundary parameter, given it does not exceed 70 bytes in length and consists only of 7-bit US-ASCII (printable) characters.

If you are using one of multipart/* content types, you are actually required to specify the boundary parameter in the Content-Type header, otherwise the server (in the case of an HTTP request) will not be able to parse the payload.

You probably also want to set the charset parameter to UTF-8 in your Content-Type header, unless you can be absolutely sure that only US-ASCII charset will be used in the payload data.

A few relevant excerpts from the RFC2046:

• 4.1.2. Charset Parameter:

  Unlike some other parameter values, the values of the charset parameter are NOT case sensitive. The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII.

• 5.1. Multipart Media Type

  As stated in the definition of the Content-Transfer-Encoding field [RFC 2045], no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The "multipart" boundary delimiters and header fields are always represented as 7bit US-ASCII in any case (though the header fields may encode non-US-ASCII header text as per RFC 2047) and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.

  The Content-Type field for multipart entities requires one parameter, "boundary". The boundary delimiter line is then defined as a line consisting entirely of two hyphen characters ("-", decimal value 45) followed by the boundary parameter value from the Content-Type header field, optional linear whitespace, and a terminating CRLF.

  Boundary delimiters must not appear within the encapsulated material, and must be no longer than 70 characters, not counting the two leading hyphens.

  The boundary delimiter line following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter line is identical to the previous delimiter lines, with the addition of two more hyphens after the boundary parameter value.

Here is an example using an arbitrary boundary:

Content-Type: multipart/form-data; charset=utf-8; boundary="another cool boundary"

--another cool boundary
Content-Disposition: form-data; name="foo"

bar
--another cool boundary
Content-Disposition: form-data; name="baz"

quux
--another cool boundary--

I had the same program, I hope this could help.

I your using Windows 7, open Command Prompt-> run as Administrator. register your <...>.dll.

Why run as Administrator, you can register your <...>.dll using the run at the Windows Start, but still your dll only run as user even your account is administrator.

Now you can add your <...>.dll at the Project->Add Reference->Browse

Thanks

Try this

Months.values()[index]

It is not possible to specify a log level in sjf4j 1.x out of the box. But there is hope for slf4j 2.0 to fix the issue. In 2.0 it might look like this:

// POTENTIAL 2.0 SOLUTION
import org.slf4j.helpers.Util;
import static org.slf4j.spi.LocationAwareLogger.*;

// does not work with slf4j 1.x
Util.log(logger, DEBUG_INT, "hello world!");

In the meanwhile, for slf4j 1.x, you can use this workaround:

Copy this class into your classpath:

import org.slf4j.Logger;
import java.util.function.Function;

public enum LogLevel {

    TRACE(l -> l::trace, Logger::isTraceEnabled),
    DEBUG(l -> l::debug, Logger::isDebugEnabled),
    INFO(l -> l::info, Logger::isInfoEnabled),
    WARN(l -> l::warn, Logger::isWarnEnabled),
    ERROR(l -> l::error, Logger::isErrorEnabled);

    interface LogMethod {
        void log(String format, Object... arguments);
    }

    private final Function<Logger, LogMethod> logMethod;
    private final Function<Logger, Boolean> isEnabledMethod;

    LogLevel(Function<Logger, LogMethod> logMethod, Function<Logger, Boolean> isEnabledMethod) {
        this.logMethod = logMethod;
        this.isEnabledMethod = isEnabledMethod;
    }

    public LogMethod prepare(Logger logger) {
        return logMethod.apply(logger);
    }

    public boolean isEnabled(Logger logger) {
        return isEnabledMethod.apply(logger);
    }
}

Then you can use it like this:

Logger logger = LoggerFactory.getLogger(Application.class);

LogLevel level = LogLevel.ERROR;
level.prepare(logger).log("It works!"); // just message, without parameter
level.prepare(logger).log("Hello {}!", "world"); // with slf4j's parameter replacing

try {
    throw new RuntimeException("Oops");
} catch (Throwable t) {
    level.prepare(logger).log("Exception", t);
}

if (level.isEnabled(logger)) {
    level.prepare(logger).log("logging is enabled");
}

This will output a log like this:

[main] ERROR Application - It works!
[main] ERROR Application - Hello world!
[main] ERROR Application - Exception
java.lang.RuntimeException: Oops
    at Application.main(Application.java:14)
[main] ERROR Application - logging is enabled

Is it worth it?

• Pro It keeps the source code location (class names, method names, line numbers will point to your code)
• Pro You can easily define variables, parameters and return types as LogLevel
• Pro Your business code stays short and easy to read, and no additional dependencies required.

The source code as minimal example is hosted on GitHub.

The datetime module has its own versions of min and max as available methods. https://docs.python.org/2/library/datetime.html

If you are under a load balancer, Laravel's \Request::ip() always returns the balancer's IP:

            echo $request->ip();
            // server ip

            echo \Request::ip();
            // server ip

            echo \request()->ip();
            // server ip

            echo $this->getIp(); //see the method below
            // clent ip

This custom method returns the real client ip:

public function getIp(){
    foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
        if (array_key_exists($key, $_SERVER) === true){
            foreach (explode(',', $_SERVER[$key]) as $ip){
                $ip = trim($ip); // just to be safe
                if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                    return $ip;
                }
            }
        }
    }
    return request()->ip(); // it will return server ip when no client ip found
}

In addition to this I suggest you to be very careful using Laravel's throttle middleware: It uses Laravel's Request::ip() as well, so all your visitors will be identified as the same user and you will hit the throttle limit very quickly. I experienced this live and this caused big issues.

To fix this:

Illuminate\Http\Request.php

    public function ip()
    {
        //return $this->getClientIp(); //original method
        return $this->getIp(); // the above method
    }

You can now also use Request::ip(), which should return the real IP in production.

You can use the following code to check if the file can be opened with exclusive access (that is, it is not opened by another application). If the file isn't closed, you could wait a few moments and check again until the file is closed and you can safely copy it.

You should still check if File.Copy fails, because another application may open the file between the moment you check the file and the moment you copy it.

public static bool IsFileClosed(string filename)
{
    try
    {
        using (var inputStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None))
        {
            return true;
        }
    }
    catch (IOException)
    {
        return false;
    }
}

If using IIS 7 or IIS 7.5 you can use

        <files>
            <clear />
            <add value="CreateThing.aspx" />

When I encountered this same error, I noticed MySQL Configuration file in "C:\Program Files\MySQL\MySQL Server X.Y\" has changed to my-default.ini

I solved it by

1. Copy my.ini from "C:\ProgramData\MySQL\MySQL Server X.Y\my.ini"
2. Paste it in "C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
3. Restart MySQL Server from services.msc

In the .ini file, their is part that reads:

# On Windows you should keep this file in the installation directory 
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
# make sure the server reads the config file use the startup option 
# "--defaults-file". 

It's entirely possible if your code has enough relative logic to work with.

Simply use the viewport units though for some the math may be a bit more complicated. I used this to prevent list items from bloating certain table columns with much longer text.

ol {max-width: 10vw; padding: 0; overflow: hidden;}

Apparently max-width on colgroup elements do not work which is pretty lame to be dependent entirely on child elements to control something on the parent.

The CSS table model is based on the HTML table model http://www.w3.org/TR/CSS21/tables.html

A table is divided into ROWS, and each row contains one or more cells. Cells are children of ROWS, they are NEVER children of columns.

"display: table-column" does NOT provide a mechanism for making columnar layouts (e.g. newspaper pages with multiple columns, where content can flow from one column to the next).

Rather, "table-column" ONLY sets attributes that apply to corresponding cells within the rows of a table. E.g. "The background color of the first cell in each row is green" can be described.

The table itself is always structured the same way it is in HTML.

In HTML (observe that "td"s are inside "tr"s, NOT inside "col"s):

<table ..>
  <col .. />
  <col .. />
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
</table>

Corresponding HTML using CSS table properties (Note that the "column" divs do not contain any contents -- the standard does not allow for contents directly in columns):

.mytable {_x000D_
  display: table;_x000D_
}_x000D_
.myrow {_x000D_
  display: table-row;_x000D_
}_x000D_
.mycell {_x000D_
  display: table-cell;_x000D_
}_x000D_
.column1 {_x000D_
  display: table-column;_x000D_
  background-color: green;_x000D_
}_x000D_
.column2 {_x000D_
  display: table-column;_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 1</div>_x000D_
    <div class="mycell">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 2</div>_x000D_
    <div class="mycell">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

OPTIONAL: both "rows" and "columns" can be styled by assigning multiple classes to each row and cell as follows. This approach gives maximum flexibility in specifying various sets of cells, or individual cells, to be styled:

//Useful css declarations, depending on what you want to affect, include:_x000D_
_x000D_
/* all cells (that have "class=mycell") */_x000D_
.mycell {_x000D_
}_x000D_
_x000D_
/* class row1, wherever it is used */_x000D_
.row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 (if you've put "class=mycell" on each cell) */_x000D_
.row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 */_x000D_
.row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows */_x000D_
.cell1 {_x000D_
}_x000D_
_x000D_
/* row1 inside class mytable (so can have different tables with different styles) */_x000D_
.mytable .row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 of a mytable */_x000D_
.mytable .row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 of a mytable */_x000D_
.mytable .row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows of a mytable */_x000D_
.mytable .cell1 {_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow row1">_x000D_
    <div class="mycell cell1">contents of first cell in row 1</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow row2">_x000D_
    <div class="mycell cell1">contents of first cell in row 2</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

In today's flexible designs, which use <div> for multiple purposes, it is wise to put some class on each div, to help refer to it. Here, what used to be <tr> in HTML became class myrow, and <td> became class mycell. This convention is what makes the above CSS selectors useful.

PERFORMANCE NOTE: putting class names on each cell, and using the above multi-class selectors, is better performance than using selectors ending with *, such as .row1 * or even .row1 > *. The reason is that selectors are matched last first, so when matching elements are being sought, .row1 * first does *, which matches all elements, and then checks all the ancestors of each element, to find if any ancestor has class row1. This might be slow in a complex document on a slow device. .row1 > * is better, because only the immediate parent is examined. But it is much better still to immediately eliminate most elements, via .row1 .cell1. (.row1 > .cell1 is an even tighter spec, but it is the first step of the search that makes the biggest difference, so it usually isn't worth the clutter, and the extra thought process as to whether it will always be a direct child, of adding the child selector >.)

The key point to take away re performance is that the last item in a selector should be as specific as possible, and should never be *.

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

The following code can help you to understand some real world use of predicates (Combined with named iterators).

namespace Predicate
{
    class Person
    {
        public int Age { get; set; }
    }
    class Program
    {
        static void Main(string[] args)
        {
            foreach (Person person in OlderThan(18))
            {
                Console.WriteLine(person.Age);
            }
        }

        static IEnumerable<Person> OlderThan(int age)
        {
            Predicate<Person> isOld = x => x.Age > age;
            Person[] persons = { new Person { Age = 10 }, new Person { Age = 20 }, new Person { Age = 19 } };

            foreach (Person person in persons)
                if (isOld(person)) yield return person;
        }
    }
}

I ran into a similar problem when trying to use the JQuery generator for Rails 3

I solved it like this:

1. Get the CURL Certificate Authority (CA) bundle. You can do this with:

   • sudo port install curl-ca-bundle [if you are using MacPorts]
   • or just pull it down directly wget http://curl.haxx.se/ca/cacert.pem

2. Execute the ruby code that is trying to verify the SSL certification: SSL_CERT_FILE=/opt/local/etc/certs/cacert.pem rails generate jquery:install. In your case, you want to either set this as an environment variable somewhere the server picks it up or add something like ENV['SSL_CERT_FILE'] = /path/to/your/new/cacert.pem in your environment.rb file.

You can also just install the CA files (I haven't tried this) to the OS -- there are lengthy instructions here -- this should work in a similar fashion, but I have not tried this personally.

Basically, the issue you are hitting is that some web service is responding with a certificate signed against a CA that OpenSSL cannot verify.

If DVI to SVG is an option, you can also use dvisvgm to convert a DVI file to an SVG file. This works perfectly for instance for LaTeX formulas (with option --no-fonts):

dvisvgm --no-fonts input.dvi -o output.svg

There is also pdf2svg which uses poppler and Cairo to convert a pdf into SVG. When I tried this, the SVG was perfectly rendered in inkscape.

You can use this code for toggle your element var ele = jQuery("yourelementid"); ele.slideToggle('slow'); this will work for you :)

It can be Cisco AnyConnect. Check if /Library/LaunchDaemons/com.cisco.anyconnect.vpnagentd.plist exists. Then unload it with launchctl and delete from /Library/LaunchDaemons

You can use jsoup or wffweb (HTML5) based.

Sample code for jsoup:-

Document doc = Jsoup.parse("<html></html>");
doc.body().addClass("body-styles-cls");
doc.body().appendElement("div");
System.out.println(doc.toString());

prints

<html>
 <head></head>
 <body class=" body-styles-cls">
  <div></div>
 </body>
</html>

Sample code for wffweb:-

Html html = new Html(null) {{
    new Head(this);
    new Body(this,
        new ClassAttribute("body-styles-cls"));
}};

Body body = TagRepository.findOneTagAssignableToTag(Body.class, html);
body.appendChild(new Div(null));

System.out.println(html.toHtmlString());
//directly writes to file
html.toOutputStream(new FileOutputStream("/home/user/filepath/filename.html"), "UTF-8");

prints (in minified format):-

<html>
<head></head>
<body class="body-styles-cls">
    <div></div>
</body>
</html>

Try this:

//String.Format("{0:HH:mm}", dt);  // where dt is a DateTime variable

public static string FormatearHoraA24(DateTime? fechaHora)
{
    if (!fechaHora.HasValue)
        return "";

    return retornar = String.Format("{0:HH:mm}", (DateTime)fechaHora);
}

public static void main(String[] args) {

    List<String> ls=new ArrayList<String>();
    ls.add("1");
    ls.add("2");
    ls.add("3");
    ls.add("4");

//Then  you can use "foreache" loop to iterate.

    for(String item:ls){
        System.out.println(item);
    }

}

This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.

So when I commented out these lines:

$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";

and set the host to

$mail->Host = "localhost";

instead

$mail->Host = 'smtp.mydomainiuse.com'

and it worked :)

Another possibility is to use a set instead of a list, if a set is applicable in your application.

IE if your data is not ordered, and does not have duplicates, then

my_set=set([3,4,2])
my_set.discard(1)

is error-free.

Often a list is just a handy container for items that are actually unordered. There are questions asking how to remove all occurences of an element from a list. If you don't want dupes in the first place, once again a set is handy.

my_set.add(3)

doesn't change my_set from above.

No. This is not possible at all.

Too late to respond. But, if this helps someone who is still facing the issue. I got this fixed by:

? Set site on dedicated pool instead of shared one.

? Enable 32 bit application support.

? Set identity of the application pool to LocalSystem.

In my case, this problem occurs when running the SpringApplication from within IntelliJ after running it first with maven.

To solve the problem, I run first mvn clean. Then I run SpringApplication from within IntelliJ.

Edit: Answered before OP clarified what he wanted. The following is for an onclick similar to javascripts onclick, not the :active pseudo class.

This can only be achieved with either Javascript or the Checkbox Hack

The checkbox hack essentially gets you to click on a label, that "checks" a checkbox, allowing you to style the label as you wish.

The demo

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

Java 7 and 8. Increment DOES change the reference, so it references to another Integer object. Look:

@Test
public void incInteger()
{
    Integer i = 5;
    Integer iOrig = i;
    ++i; // Same as i = i + 1;
    Assert.assertEquals(6, i.intValue());
    Assert.assertNotEquals(iOrig, i);
}

Integer by itself is still immutable.

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

To really convert from a string to a number properly, you need to use an instance of NSNumberFormatter configured for the locale from which you're reading the string.

Different locales will format numbers differently. For example, in some parts of the world, COMMA is used as a decimal separator while in others it is PERIOD — and the thousands separator (when used) is reversed. Except when it's a space. Or not present at all.

It really depends on the provenance of the input. The safest thing to do is configure an NSNumberFormatter for the way your input is formatted and use -[NSFormatter numberFromString:] to get an NSNumber from it. If you want to handle conversion errors, you can use -[NSFormatter getObjectValue:forString:range:error:] instead.

I was having session file not found error while tried various ways, finally achieved like this. Made the function as static (which I want to call in the another controller), and called like

require_once('Welcome.php');
Welcome::hello();

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

I ran into the same issue. It appeared Citable Documents per Person was a float, and python skips it somehow by default. All the other columns of my dataframe were in numpy-formats, so I solved it by converting the columnt to np.float64

Top15['Citable Documents per Person']=np.float64(Top15['Citable Documents per Person'])

Remember it's exactly the column you calculated yourself

FYI, it looks like the syntax for retrieving the values has changed according to:

http://freemarker.sourceforge.net/docs/ref_builtins_hash.html

<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>

Use .net inbuilt class JavaScriptSerializer

  JavaScriptSerializer js = new JavaScriptSerializer();
  string json = js.Serialize(obj);

Don't change the name of the dockerfile if you want to use the autobuilder at hub.docker.com. Don't use an extension for docker files, leave it null. File name should just be: (no extension at all)

In my case the ajax call was being interfered by the data-plugin tag applied to the table. The data-plugin does background initialization and will give this error when you have it as well as yourTable.DataTable({ ... }); initialization.

From

 <table id="myTable" class="table-class" data-plugin="dataTable" data-source="data-source">

To

<table id="myTable" class="table-class" data-source="data-source">

//*[text()='ABC'] 

returns

<street>ABC</street>
<comment>BLAH BLAH BLAH <br><br>ABC</comment>

will the height attribute stretch the image beyond its native resolution? If I have a image with a height of say 420 pixels, I can't get css to stretch the image beyond the native resolution to fill the height of the viewport.

I am getting pretty close results with:

 .rightdiv img {
        max-width: 25vw;
        min-height: 100vh;
    }

the 100vh is getting pretty close, with just a few pixels left over at the bottom for some reason.

This will print out a hexadecimal representation of a pthread_t, no matter what that actually is:

void fprintPt(FILE *f, pthread_t pt) {
  unsigned char *ptc = (unsigned char*)(void*)(&pt);
  fprintf(f, "0x");
  for (size_t i=0; i<sizeof(pt); i++) {
    fprintf(f, "%02x", (unsigned)(ptc[i]));
  }
}

To just print a small id for a each pthread_t something like this could be used (this time using iostreams):

void printPt(std::ostream &strm, pthread_t pt) {
  static int nextindex = 0;
  static std::map<pthread_t, int> ids;
  if (ids.find(pt) == ids.end()) {
    ids[pt] = nextindex++;
  }
  strm << ids[pt];
}

Depending on the platform and the actual representation of pthread_t it might here be necessary to define an operator< for pthread_t, because std::map needs an ordering on the elements:

bool operator<(const pthread_t &left, const pthread_t &right) {
  ...
}

You can send the array to this function:

function utf8_converter($array){
    array_walk_recursive($array, function(&$item, $key){
        if(!mb_detect_encoding($item, 'utf-8', true)){
            $item = utf8_encode($item);
        }
    }); 
    return $array;
}

It works for me.

Python 3

In Python 3, this question doesn't apply. The plain int type is unbounded.

However, you might actually be looking for information about the current interpreter's word size, which will be the same as the machine's word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the maximum value representable by a signed word. Equivalently, it's the size of the largest possible list or in-memory sequence.

Generally, the maximum value representable by an unsigned word will be sys.maxsize * 2 + 1, and the number of bits in a word will be math.log2(sys.maxsize * 2 + 2). See this answer for more information.

Python 2

In Python 2, the maximum value for plain int values is available as sys.maxint:

>>> sys.maxint
9223372036854775807

You can calculate the minimum value with -sys.maxint - 1 as shown here.

Python seamlessly switches from plain to long integers once you exceed this value. So most of the time, you won't need to know it.

This is little more explanation for pass by value and pass by reference (JavaScript). In this concept, they are talking about passing the variable by reference and passing the variable by reference.

Pass by value (primitive type)

var a = 3;
var b = a;

console.log(a); // a = 3
console.log(b); // b = 3

a=4;
console.log(a); // a = 4
console.log(b); // b = 3

• applies to all primitive type in JavaScript (string, number, Boolean, undefined, and null).
• a is allocated a memory (say 0x001) and b creates a copy of the value in memory (say 0x002).
• So changing the value of a variable doesn't affect the other, as they both reside in two different locations.

Pass by reference (objects)

var c = { "name" : "john" };
var d = c;

console.log(c); // { "name" : "john" }
console.log(d); // { "name" : "john" }

c.name = "doe";

console.log(c); // { "name" : "doe" }
console.log(d); // { "name" : "doe" }

• The JavaScript engine assigns the object to the variable c, and it points to some memory, say (0x012).
• When d=c, in this step d points to the same location (0x012).
• Changing the value of any changes value for both the variable.
• Functions are objects

Special case, pass by reference (objects)

c = {"name" : "jane"};
console.log(c); // { "name" : "jane" }
console.log(d); // { "name" : "doe" }

• The equal(=) operator sets up new memory space or address

I was using CMake & then added a win32 configuration. The property page showed x86 but actually when opening the vcxproj file in a text editor it was x64! Manually changing to x86 solved this.

If the function is from a source file available on the filesystem, then inspect.getsource(foo) might be of help:

If foo is defined as:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a  

Then:

import inspect
lines = inspect.getsource(foo)
print(lines)

Returns:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a                

But I believe that if the function is compiled from a string, stream or imported from a compiled file, then you cannot retrieve its source code.

An example using C#

//abstraction - exposing only the relevant behavior
public interface IMakeFire
{
     void LightFire();
}

//encapsulation - hiding things that the rest of the world doesn't need to see
public class Caveman: IMakeFire
{
     //exposed information  
     public string Name {get;set;}

     // exposed but unchangeable information
     public byte Age {get; private set;}

     //internal i.e hidden object detail. This can be changed freely, the outside world
     // doesn't know about it
     private bool CanMakeFire()
     {  
         return Age >7;
     }

     //implementation of a relevant feature
     public void LightFire()
     {
        if (!CanMakeFire())
        {
           throw new UnableToLightFireException("Too young");
        }
        GatherWood();
        GetFireStone();
        //light the fire

     }

     private GatherWood() {};
     private GetFireStone();
}

public class PersonWithMatch:IMakeFire
{
      //implementation
 }

Any caveman can make a fire, because it implements the IMakeFire 'feature'. Having a group of fire makers (List) this means that both Caveman and PersonWithMatch are valid choises.

This means that

  //this method (and class) isn't coupled to a Caveman or a PersonWithMatch
  // it can work with ANY object implementing IMakeFire
  public void FireStarter(IMakeFire starter)
  {
        starter.LightFire();
    }

So you can have lots of implementors with plenty of details (properties) and behavior(methods), but in this scenario what matters is their ability to make fire. This is abstraction.

Since making a fire requires some steps (GetWood etc), these are hidden from the view as they are an internal concern of the class. The caveman has many other public behaviors which can be called by the outside world. But some details will be always hidden because are related to internal working. They're private and exist only for the object, they are never exposed. This is encapsulation

This is really easy using a JavaScript library, e.g. using jQuery you could write:

$(document).ready(function(){
$.ajax({ url: "database/update.html",
        context: document.body,
        success: function(){
           alert("done");
        }});
});

Without jQuery, the simplest version might be as follows, but it does not account for browser differences or error handling:

<html>
  <body onload="updateDB();">
  </body>
  <script language="javascript">
    function updateDB() {
      var xhr = new XMLHttpRequest();
      xhr.open("POST", "database/update.html", true);
      xhr.send(null);
      /* ignore result */
    }
  </script>
</html>

Steps for Using Group by,Having By and Order by...

Select Attitude ,count(*) from Person
group by person
HAving PersonAttitude='cool and friendly'
Order by PersonName.

A clustered index means you are telling the database to store close values actually close to one another on the disk. This has the benefit of rapid scan / retrieval of records falling into some range of clustered index values.

For example, you have two tables, Customer and Order:

Customer
----------
ID
Name
Address

Order
----------
ID
CustomerID
Price

If you wish to quickly retrieve all orders of one particular customer, you may wish to create a clustered index on the "CustomerID" column of the Order table. This way the records with the same CustomerID will be physically stored close to each other on disk (clustered) which speeds up their retrieval.

P.S. The index on CustomerID will obviously be not unique, so you either need to add a second field to "uniquify" the index or let the database handle that for you but that's another story.

Regarding multiple indexes. You can have only one clustered index per table because this defines how the data is physically arranged. If you wish an analogy, imagine a big room with many tables in it. You can either put these tables to form several rows or pull them all together to form a big conference table, but not both ways at the same time. A table can have other indexes, they will then point to the entries in the clustered index which in its turn will finally say where to find the actual data.

        $services = $this->Service->find('all', array(
            'limit' =>4,
            'fields' => array('Service.*','ServiceImage.*'),
            'joins' => array(
                array(
                        'table' => 'services_images',
                        'alias' => 'ServiceImage',
                        'type' => 'INNER',
                        'conditions' => array(
                        'ServiceImage.service_id' =>'Service.id'
                        )
                    ),
                ),
            )
        );

It goges to array is null.

To select columns to plot, I added 2 lines to Vincent Zoonekynd's answer:

#convert to tall/long format(from wide format)
col_plot = c("A","B")
dlong <- melt(d[,c("Xax", col_plot)], id.vars="Xax")  

#"value" and "variable" are default output column names of melt()
ggplot(dlong, aes(Xax,value, col=variable)) +
  geom_point() + 
  geom_smooth()

Google "tidy data" to know more about tall(or long)/wide format.

The first things popping up

EXTRACT(EPOCH FROM current_timestamp-somedate)/3600

May not be pretty, but unblocks the road. Could be prettier if division of interval by interval was defined.

Edit: if you want it greater than zero either use abs or greatest(...,0). Whichever suits your intention.

Edit++: the reason why I didn't use age is that age with a single argument, to quote the documentation: Subtract from current_date (at midnight). Meaning you don't get an accurate "age" unless running at midnight. Right now it's almost 1am here:

select age(current_timestamp);
       age        
------------------
 -00:52:40.826309
(1 row)

In case anyone had the same problem: check this as @PravinS suggested. I used the exact same code as shown there and it worked for me perfectly.

This is the relevant part of the server code that helped:

if (isset($_POST['btnUpload']))
{
$url = "URL_PATH of upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
$filename = $_FILES['file']['name'];
$filedata = $_FILES['file']['tmp_name'];
$filesize = $_FILES['file']['size'];
if ($filedata != '')
{
    $headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
    $postfields = array("filedata" => "@$filedata", "filename" => $filename);
    $ch = curl_init();
    $options = array(
        CURLOPT_URL => $url,
        CURLOPT_HEADER => true,
        CURLOPT_POST => 1,
        CURLOPT_HTTPHEADER => $headers,
        CURLOPT_POSTFIELDS => $postfields,
        CURLOPT_INFILESIZE => $filesize,
        CURLOPT_RETURNTRANSFER => true
    ); // cURL options
    curl_setopt_array($ch, $options);
    curl_exec($ch);
    if(!curl_errno($ch))
    {
        $info = curl_getinfo($ch);
        if ($info['http_code'] == 200)
            $errmsg = "File uploaded successfully";
    }
    else
    {
        $errmsg = curl_error($ch);
    }
    curl_close($ch);
}
else
{
    $errmsg = "Please select the file";
}
}

html form should look something like:

<form action="uploadpost.php" method="post" name="frmUpload" enctype="multipart/form-data">
<tr>
  <td>Upload</td>
  <td align="center">:</td>
  <td><input name="file" type="file" id="file"/></td>
</tr>
<tr>
  <td>&nbsp;</td>
  <td align="center">&nbsp;</td>
  <td><input name="btnUpload" type="submit" value="Upload" /></td>
</tr>

A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.

You can also SELECT the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.

I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.

Hope this is of use.

This doesn't work because NaN isn't equal to anything, including NaN. Use pd.isnull(df.var2) instead.

For sql server (SSMS)

select MAX(LEN(ColumnName)) from table_name

This will returns number of characters.

 select MAX(DATALENGTH(ColumnName)) from table_name

This will returns number of bytes used/required.

IF some one use varchar then use DATALENGTH.More details

Use:

int rename(const char * oldname, const char * newname);

The rename() function is defined in the stdio.h header file. It renames a file or directory from oldname to newname. The rename operation is the same as move, hence you can also use this function to move a file.

DECLARE @CarList nvarchar(max);
SET @CarList = N'';
SELECT @CarList+=CarName+N','
FROM dbo.CARS;
SELECT LEFT(@CarList,LEN(@CarList)-1);

Thanks are due to whoever on SO showed me the use of accumulating data during a query.

Current css version still doesn't support selector find by content. But there is a way, by using css selector find by attribute, but you have to put some identifier on all of the <td> that have $ inside. Example: using nth-child in tables tr td

html

<tr>
    <td>&nbsp;</td>
    <td data-rel='$'>$</td>
    <td>&nbsp;</td>
</tr>

css

table tr td[data-rel='$'] {
    background-color: #333;
    color: white;
}

Please try these example.

table tr td[data-content='$'] {_x000D_
    background-color: #333;_x000D_
    color: white;_x000D_
}

<table border="1">_x000D_
    <tr>_x000D_
        <td>A</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>B</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>C</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>D</td>_x000D_
    </tr>_x000D_

They changed the packaging for psycopg2. Installing the binary version fixed this issue for me. The above answers still hold up if you want to compile the binary yourself.

See http://initd.org/psycopg/docs/news.html#what-s-new-in-psycopg-2-8.

Binary packages no longer installed by default. The ‘psycopg2-binary’ package must be used explicitly.

And http://initd.org/psycopg/docs/install.html#binary-install-from-pypi

So if you don't need to compile your own binary, use:

pip install psycopg2-binary

VLookup

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

Theano does have support for OpenCL but it is still in its early stages. Theano itself is not interested in OpenCL and relies on community support.

Most of the operations are already implemented and it is mostly a matter of tuning and optimizing the given operations.

To use the OpenCL backend you have to build libgpuarray yourself.

From personal experience I can tell you that you will get CPU performance if you are lucky. The memory allocation seems to be very naively implemented (therefore computation will be slow) and will crash when it runs out of memory. But I encourage you to try and maybe even optimize the code or help reporting bugs.

First I think you need to fix your lists, as the first node of a <ul> must be a <li> (stackoverflow ref). Once that is setup you can do this:

// note this array has outer scope
var phrases = [];

$('.phrase').each(function(){
        // this is inner scope, in reference to the .phrase element
        var phrase = '';
        $(this).find('li').each(function(){
            // cache jquery var
            var current = $(this);
            // check if our current li has children (sub elements)
            // if it does, skip it
            // ps, you can work with this by seeing if the first child
            // is a UL with blank inside and odd your custom BLANK text
            if(current.children().size() > 0) {return true;}
            // add current text to our current phrase
            phrase += current.text();
        });
        // now that our current phrase is completely build we add it to our outer array
        phrases.push(phrase);
    });
    // note the comma in the alert shows separate phrases
    alert(phrases);

Working jsfiddle.

One thing is if you get the .text() of an upper level li you will get all sub level text with it.

Keeping an array will allow for many multiple phrases to be extracted.

EDIT:

This should work better with an empty UL with no LI:

// outer scope
var phrases = [];

$('.phrase').each(function(){
    // inner scope
    var phrase = '';
    $(this).find('li').each(function(){
        // cache jquery object
        var current = $(this);
        // check for sub levels
        if(current.children().size() > 0) {
            // check is sublevel is just empty UL
            var emptyULtest = current.children().eq(0); 
            if(emptyULtest.is('ul') && $.trim(emptyULtest.text())==""){
                phrase += ' -BLANK- '; //custom blank text
                return true;   
            } else {
             // else it is an actual sublevel with li's
             return true;   
            }
        }
        // if it gets to here it is actual li
        phrase += current.text();
    });
    phrases.push(phrase);
});
// note the comma to separate multiple phrases
alert(phrases);

DateTime.ParseExact(monthName, "MMMM", CultureInfo.CurrentCulture ).Month

Although, for your purposes, you'll probably be better off just creating a Dictionary<string, int> mapping the month's name to its value.

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

The -H 'Cache-Control: no-cache' argument is not guaranteed to work because the remote server or any proxy layers in between can ignore it. If it doesn't work, you can do it the old-fashioned way, by adding a unique querystring parameter. Usually, the servers/proxies will think it's a unique URL and not use the cache.

curl "http://www.example.com?foo123"

You have to use a different querystring value every time, though. Otherwise, the server/proxies will match the cache again. To automatically generate a different querystring parameter every time, you can use date +%s, which will return the seconds since epoch.

curl "http://www.example.com?$(date +%s)"

It's easy to get this error in a multi-module project. If, for example, you made changes to modules A, B, and C, but then you try to compile just module B, you are susceptible to this error. Say module B has a dependency on module A. Since only module B was compiled, the class files from module A are now out of date and possibly invalid.

Compiling all the modules (or modules in the proper hierarchical dependency order) resolves this error, if this is the nature of your problem.

Before MySQL 5.7.6 this works from the command line:

mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('$w0rdf1sh');"

I don't have a mysql install to test on but I think in your case it would be

mysql -e "UPDATE mysql.user SET Password=PASSWORD('$w0rdf1sh') WHERE User='tate256';"

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

A somewhat different approach (at least on Android) is to use the IntDef annotation to combine a set of int constants

@IntDef({NOTAX, SALESTAX, IMPORTEDTAX})
@interface TAX {}
int NOTAX = 0;
int SALESTAX = 10;
int IMPORTEDTAX = 5;

Use as function parameter:

void computeTax(@TAX int taxPercentage){...} 

or in a variable declaration:

@TAX int currentTax = IMPORTEDTAX;

For standard OS X installations of MySQL you will find my.cnf located in the /etc/ folder.

Steps to update this variable:

1. Load Terminal.
2. Type cd /etc/.
3. sudo vi my.cnf.
4. This file should already exist (if not please use sudo find / -name 'my.cnf' 2>1 - this will hide the errors and only report the successfile file location).
5. Using vi(m) find the line innodb_buffer_pool_size, press i to start making changes.
6. When finished, press esc, shift+colon and type wq.
7. Profit (done).

In testing IE7/8/9 I was getting an ActiveX warning trying to use this code snippet:

filter:progid:DXImageTransform.Microsoft.gradient

After removing this the warning went away. I know this isn't an answer, but I thought it was worthwhile to note.

I found it easier to edit the project file directly e.g. YourApp.csproj.

You can do this by modifying ApplicationIcon property element:

<ApplicationIcon>..\Path\To\Application.ico</ApplicationIcon>

Also, if you create an MSI installer for your application e.g. using WiX, you can use the same icon again for display in Add/Remove Programs. See tip 5 here.

Uses the jquery prop() to clear the selected option

$('#mySelect option:selected').prop('selected', false);

I tend to create a static class containing basic functions for cases like these. They allow me write expressions like

var myValues myItems.Select(x => x.Value).Where(Predicates.IsNotNull);

And the collection of predicate functions:

public static class Predicates
{
    public static bool IsNull<T>(T value) where T : class
    {
        return value == null;
    }

    public static bool IsNotNull<T>(T value) where T : class
    {
        return value != null;
    }

    public static bool IsNull<T>(T? nullableValue) where T : struct
    {
        return !nullableValue.HasValue;
    }

    public static bool IsNotNull<T>(T? nullableValue) where T : struct
    {
        return nullableValue.HasValue;
    }

    public static bool HasValue<T>(T? nullableValue) where T : struct
    {
        return nullableValue.HasValue;
    }

    public static bool HasNoValue<T>(T? nullableValue) where T : struct
    {
        return !nullableValue.HasValue;
    }
}

You could use char.IsDigit:

     bool isIntString = "your string".All(char.IsDigit)

Will return true if the string is a number

    bool containsInt = "your string".Any(char.IsDigit)

Will return true if the string contains a digit

This may work

    ::selection {
        color: none;
        background: none;
    }
    /* For Mozilla Firefox */
    ::-moz-selection {
        color: none;
        background: none;
    }

Time flies!

On version 12, I have to use "password" instead of "ident" here:

local   all             postgres                                password

Connect without using the -h option.

I had \bin as part of the path. Up one level of the selected directory worked for me.

"/^([^\/]*)\/$/" worked for me, to get only top "folders" from an array like:

a/   <- this
a/b/
c/   <- this
c/d/
/d/e/
f/   <- this

I use this in my utils library (Swift 4.2):

public class PrintTimer {
    let start = Date()
    let name: String

    public init(file: String=#file, line: Int=#line, function: String=#function, name: String?=nil) {
        let file = file.split(separator: "/").last!
        self.name = name ?? "\(file):\(line) - \(function)"
    }

    public func done() {
        let end = Date()
        print("\(self.name) took \((end.timeIntervalSinceReferenceDate - self.start.timeIntervalSinceReferenceDate).roundToSigFigs(5)) s.")
    }
}

... then call in a method like:

func myFunctionCall() {
    let timer = PrintTimer()
    // ...
    timer.done()
}

... which in turn looks like this in the console after running:

MyFile.swift:225 - myFunctionCall() took 1.8623 s.

Not as concise as TICK/TOCK above, but it is clear enough to see what it is doing and automatically includes what is being timed (by file, line at the start of the method, and function name). Obviously if I wanted more detail (ex, if I'm not just timing a method call as is the usual case but instead am timing a block within that method) I can add the "name="Foo"" parameter on the PrintTimer init to name it something besides the defaults.

If you are using the new Navigation Component, is simple as

findNavController().popBackStack()

It will do all the FragmentTransaction in behind for you.

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

You don't need jquery for this, in plain javascript, the following will work!

var intervalId = window.setInterval(function(){
  /// call your function here
}, 5000);

To stop the loop you can use

clearInterval(intervalId) 

Is the following acceptable:

$('#myTableRow').remove();

I use block-mode visual selection:

• Go to the front of the block to move (at the top or bottom).
• Press Ctrl + V to enter visual block mode.
• Navigate to select a column in front of the lines.
• Press I (Shift + I) to enter insert mode.
• Type some spaces.
• Press Esc. All lines will shift.

This is not a uni-tasker. It works:

• In the middle of lines.
• To insert any string on all lines.
• To change a column (use c instead of I).
• yank, delete, substitute, etc...

You can use the he library, available from https://github.com/mathiasbynens/he

Example:

console.log(he.decode("Jörg &amp Jürgen rocked to & fro "));
// Logs "Jörg & Jürgen rocked to & fro"

I challenged the library's author on the question of whether there was any reason to use this library in clientside code in favour of the <textarea> hack provided in other answers here and elsewhere. He provided a few possible justifications:

• If you're using node.js serverside, using a library for HTML encoding/decoding gives you a single solution that works both clientside and serverside.

• Some browsers' entity decoding algorithms have bugs or are missing support for some named character references. For example, Internet Explorer will both decode and render non-breaking spaces ( ) correctly but report them as ordinary spaces instead of non-breaking ones via a DOM element's innerText property, breaking the <textarea> hack (albeit only in a minor way). Additionally, IE 8 and 9 simply don't support any of the new named character references added in HTML 5. The author of he also hosts a test of named character reference support at http://mathias.html5.org/tests/html/named-character-references/. In IE 8, it reports over one thousand errors.

  If you want to be insulated from browser bugs related to entity decoding and/or be able to handle the full range of named character references, you can't get away with the <textarea> hack; you'll need a library like he.

• He just darn well feels like doing things this way is less hacky.

var reader = cmd.ExecuteReader();

var columns = new List<string>();

for(int i=0;i<reader.FieldCount;i++)
{
   columns.Add(reader.GetName(i));
}

or

var columns = Enumerable.Range(0, reader.FieldCount).Select(reader.GetName).ToList();

I should point out that none of the answers provided so far give you the number of characters as you would expect, especially when you're dealing with emojis (but also some languages like Thai, Korean, or Arabic). VonC's suggestions will output the following:

fmt.Println(utf8.RuneCountInString("??")) // Outputs "6".
fmt.Println(len([]rune("??"))) // Outputs "6".

That's because these methods only count Unicode code points. There are many characters which can be composed of multiple code points.

Same for using the Normalization package:

var ia norm.Iter
ia.InitString(norm.NFKD, "??")
nc := 0
for !ia.Done() {
    nc = nc + 1
    ia.Next()
}
fmt.Println(nc) // Outputs "6".

Normalization is not really the same as counting characters and many characters cannot be normalized into a one-code-point equivalent.

masakielastic's answer comes close but only handles modifiers (the rainbow flag contains a modifier which is thus not counted as its own code point):

fmt.Println(GraphemeCountInString("??"))  // Outputs "5".
fmt.Println(GraphemeCountInString2("??")) // Outputs "5".

The correct way to split Unicode strings into (user-perceived) characters, i.e. grapheme clusters, is defined in the Unicode Standard Annex #29. The rules can be found in Section 3.1.1. The github.com/rivo/uniseg package implements these rules so you can determine the correct number of characters in a string:

fmt.Println(uniseg.GraphemeClusterCount("??")) // Outputs "2".

Use \Q to autoescape any potentially problematic characters in your variable.

if($text_to_search =~ m/\Q$search_string/) print "wee";

Make sure the folder with the standard header files is in the projects path.

I don't know where this is in Turbo C, but I would think there's a way of doing this.

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

If you're looking to paginate results, use the integrated paginator, it works great!

$games = Game::paginate(30);
// $games->results = the 30 you asked for
// $games->links() = the links to next, previous, etc pages

There are several ways:

Write-Host: Write directly to the console, not included in function/cmdlet output. Allows foreground and background colour to be set.

Write-Debug: Write directly to the console, if $DebugPreference set to Continue or Stop.

Write-Verbose: Write directly to the console, if $VerbosePreference set to Continue or Stop.

The latter is intended for extra optional information, Write-Debug for debugging (so would seem to fit in this case).

Additional: In PSH2 (at least) scripts using cmdlet binding will automatically get the -Verbose and -Debug switch parameters, locally enabling Write-Verbose and Write-Debug (i.e. overriding the preference variables) as compiled cmdlets and providers do.

The querySelectorAll() method returns all elements in the document that matches a specified CSS selector(s), as a static NodeList object.

The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0.

For more interesting scenarios, you could also look at the runpy module. Since python 2.7, it has the run_path function. E.g:

import runpy
import sys

# argv[0] will be replaced by runpy
# You could also skip this if you get sys.argv populated
# via other means
sys.argv = ['', 'arg1' 'arg2']
runpy.run_path('./abc.py', run_name='__main__')

Using the pathlib module (python's object-oriented filesystem paths)

Just for kicks, this is perhaps the latest pythonic version of the solution.

from pathlib import Path 

path = Path(f'{player}.txt')
path.touch()  # default exists_ok=True
with path.open('a') as highscore:
   highscore.write(f'Username:{player}')

I want to improve Fabio's answer and create a function which adds custom key to the URL string without reloading the page.

function insertUrlParam(key, value) {
    if (history.pushState) {
        let searchParams = new URLSearchParams(window.location.search);
        searchParams.set(key, value);
        let newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?' + searchParams.toString();
        window.history.pushState({path: newurl}, '', newurl);
    }
}

You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."

Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.

Update:

The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg

Yes, it will always be the same. From the documentation

Appends the specified element to the end of this list. Parameters: e element to be appended to this list Returns: true (as specified by Collection.add(java.lang.Object))

ArrayList add() implementation

public boolean More ...add(E e) {
    ensureCapacity(size + 1);  // Increments modCount!!
    elementData[size++] = e;
    return true;
}

If the other tips here don't work and - just like me - you're using the pandas integration through progress_apply, you can let tqdm handle it:

from tqdm.autonotebook import tqdm
tqdm.pandas()

df.progress_apply(row_function, axis=1)

The main point here lies in the tqdm.autonotebook module. As stated in their instructions for use in IPython Notebooks, this makes tqdm choose between progress bar formats used in Jupyter notebooks and Jupyter consoles - for a reason still lacking further investigations on my side, the specific format chosen by tqdm.autonotebook works smoothly in pandas, while all others didn't, for progress_apply specifically.

If you iterate over a dictionary you get the keys, so assuming your dictionary is in a variable called data and you have some function find_definition() which gets the definition, you can do something like the following:

for word in data:
    data[word] = find_definition(word)

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

str = "aaaaabbbb"
newstr = str[-4:]

See : http://codepad.org/S3zjnKoD

\1 in double quotes needs to be escaped. So you want either

"Z_sdsd: sdsd".gsub(/^(Z_.*): .*/, "\\1")

or

"Z_sdsd: sdsd".gsub(/^(Z_.*): .*/, '\1')

see the docs on gsub where it says "If it is a double-quoted string, both back-references must be preceded by an additional backslash."

That being said, if you just want the result of the match you can do:

"Z_sdsd: sdsd".scan(/^Z_.*(?=:)/)

or

"Z_sdsd: sdsd"[/^Z_.*(?=:)/]

Note that the (?=:) is a non-capturing group so that the : doesn't show up in your match.

You can use this extension:

extension String {

    static func isNilOrEmpty(string: String?) -> Bool {
        guard let value = string else { return true }

        return value.trimmingCharacters(in: .whitespaces).isEmpty
    }

}

and then use it like this:

let isMyStringEmptyOrNil = String.isNilOrEmpty(string: myString)

Another option would be as the return value for the stored procedure (I don't suggest this though, as that's usually best for error values).

I've included it as both when it's inserting a single row in cases where the stored procedure was being consumed by both other SQL procedures and a front-end which couldn't work with OUTPUT parameters (IBATIS in .NET I believe):

CREATE PROCEDURE My_Insert
    @col1            VARCHAR(20),
    @new_identity    INT    OUTPUT
AS
BEGIN
    SET NOCOUNT ON

    INSERT INTO My_Table (col1)
    VALUES (@col1)

    SELECT @new_identity = SCOPE_IDENTITY()

    SELECT @new_identity AS id

    RETURN
END

The output parameter is easier to work with in T-SQL when calling from other stored procedures IMO, but some programming languages have poor or no support for output parameters and work better with result sets.

Use display:none to not show the items, then with JQuery you can use fadeIn() and fadeOut() to hide/unhide the elements.

I juste made this code, from some StackOverflow discussions. I didn't test on Linux environment yet. It is made in order to delete a file or a directory, completely :

function splRm(SplFileInfo $i)
{
    $path = $i->getRealPath();

    if ($i->isDir()) {
        echo 'D - ' . $path . '<br />';
        rmdir($path);
    } elseif($i->isFile()) {
        echo 'F - ' . $path . '<br />';
        unlink($path);
    }
}

function splRrm(SplFileInfo $j)
{
    $path = $j->getRealPath();

    if ($j->isDir()) {
        $rdi = new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS);
        $rii = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST);
        foreach ($rii as $i) {
            splRm($i);
        }
    }
    splRm($j);

}

splRrm(new SplFileInfo(__DIR__.'/../dirOrFileName'));

According to the standards, pwd -P should return the path with symlinks resolved.

C function char *getcwd(char *buf, size_t size) from unistd.h should have the same behaviour.

getcwd pwd

Assuming you want the format "(123) 456-7890":

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    return '(' + match[1] + ') ' + match[2] + '-' + match[3]
  }
  return null
}

Here's a version that allows the optional +1 international code:

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(1|)?(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    var intlCode = (match[1] ? '+1 ' : '')
    return [intlCode, '(', match[2], ') ', match[3], '-', match[4]].join('')
  }
  return null
}
formatPhoneNumber('+12345678900') // => "+1 (234) 567-8900"
formatPhoneNumber('2345678900')   // => "(234) 567-8900"

I suppese you alredy managed to solve it, but if someone is looking for similar solution then this worked for me:

 g.append('svg:text')
  .attr('x', 0)
  .attr('y', 30)
  .attr('class', 'id')
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 5)
  .text(function(d) { return d.name; })
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 20)
  .text(function(d) { return d.sname; })
  .append('svg:tspan')
  .attr('x', 0)
  .attr('dy', 20)
  .text(function(d) { return d.idcode; })

There are 3 lines separated with linebreak.

Here's a minor update to the solution provided by Dave Sexton. Many times you need multiple filters. The Filter parameter can only take a single string whereas the -Include parameter can take a string array. if you have a large file tree it also makes sense to only get the date to compare with once, not for each file. Here's my updated version:

$compareDate = (Get-Date).AddDays(-3)    
@(Get-ChildItem -Path c:\pstbak\*.* -Filter '*.pst','*.mdb' -Recurse | Where-Object { $_.LastWriteTime -gt $compareDate}).Count

var cultureInfo = CultureInfo.CurrentCulture;
var calendar = cultureInfo.Calendar;

var calendarWeekRule = cultureInfo.DateTimeFormat.CalendarWeekRule;
var firstDayOfWeek = cultureInfo.DateTimeFormat.FirstDayOfWeek;
var lastDayOfWeek = cultureInfo.LCID == 1033 //En-us
                    ? DayOfWeek.Saturday
                    : DayOfWeek.Sunday;

var lastDayOfYear = new DateTime(date.Year, 12, 31);

var weekNumber = calendar.GetWeekOfYear(date, calendarWeekRule, firstDayOfWeek);

 //Check if this is the last week in the year and it doesn`t occupy the whole week
return weekNumber == 53 && lastDayOfYear.DayOfWeek != lastDayOfWeek 
       ? 1  
       : weekNumber;

It works well both for US and Russian cultures. ISO 8601 also will be correct, `cause Russian week starts at Monday.

Assuming you still want to get the URL without the query args (if they are not set), just use a shorthand if statement to check with strpos:

$request_uri = strpos( $_SERVER['REQUEST_URI'], '?' ) !== false ? strtok( $_SERVER["REQUEST_URI"], '?' ) : $_SERVER['REQUEST_URI'];

In ruby 2.0 you can now just use %

For example:

    SQL = %{
      SELECT user, name
      FROM users
      WHERE users.id = #{var}
      LIMIT #{var2}
    }

$_SERVER['HTTP_REFERER'] is the answer

First, this is the directory layout that I am using:

.
+-- include
¦   +-- class1.hpp
¦   +-- ...
¦   +-- class2.hpp
+-- src
    +-- class1.cpp
    +-- ...
    +-- class2.cpp

After a couple of days taking a look into this, this is my favourite way of doing this thanks to modern CMake:

cmake_minimum_required(VERSION 3.5)
project(mylib VERSION 1.0.0 LANGUAGES CXX)

set(DEFAULT_BUILD_TYPE "Release")

if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES)
  message(STATUS "Setting build type to '${DEFAULT_BUILD_TYPE}' as none was specified.")
  set(CMAKE_BUILD_TYPE "${DEFAULT_BUILD_TYPE}" CACHE STRING "Choose the type of build." FORCE)
  # Set the possible values of build type for cmake-gui
  set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS "Debug" "Release" "MinSizeRel" "RelWithDebInfo")
endif()

include(GNUInstallDirs)

set(SOURCE_FILES src/class1.cpp src/class2.cpp)

add_library(${PROJECT_NAME} ...)

target_include_directories(${PROJECT_NAME} PUBLIC
    $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
    $<INSTALL_INTERFACE:include>
    PRIVATE src)

set_target_properties(${PROJECT_NAME} PROPERTIES
    VERSION ${PROJECT_VERSION}
    SOVERSION 1)

install(TARGETS ${PROJECT_NAME} EXPORT MyLibConfig
    ARCHIVE  DESTINATION ${CMAKE_INSTALL_LIBDIR}
    LIBRARY  DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME  DESTINATION ${CMAKE_INSTALL_BINDIR})
install(DIRECTORY include/ DESTINATION ${CMAKE_INSTALL_INCLUDEDIR}/${PROJECT_NAME})

install(EXPORT MyLibConfig DESTINATION share/MyLib/cmake)

export(TARGETS ${PROJECT_NAME} FILE MyLibConfig.cmake)

After running CMake and installing the library, there is no need to use Find***.cmake files, it can be used like this:

find_package(MyLib REQUIRED)

#No need to perform include_directories(...)
target_link_libraries(${TARGET} mylib)

That's it, if it has been installed in a standard directory it will be found and there is no need to do anything else. If it has been installed in a non-standard path, it is also easy, just tell CMake where to find MyLibConfig.cmake using:

cmake -DMyLib_DIR=/non/standard/install/path ..

I hope this helps everybody as much as it has helped me. Old ways of doing this were quite cumbersome.

you can find it by going to xcode > open developer tool > application Loader

you can copy the export file for e.g dump.sql using docker cp into the container and then import the db. if you need full instructions, let me know and I will provide

Crude, but does what you want, breaks the execution scope:

$(function(){
setTimeout(function(){
//Code to call
},1);
});

If your using ng-repeat $index works like this

  name="QTY{{$index}}"

and

   <td>
       <input ng-model="r.QTY" class="span1" name="QTY{{$index}}" ng-            
        pattern="/^[\d]*\.?[\d]*$/" required/>
        <span class="alert-error" ng-show="form['QTY' + $index].$error.pattern">
        <strong>Requires a number.</strong></span>
        <span class="alert-error" ng-show="form['QTY' + $index].$error.required">
       <strong>*Required</strong></span>
    </td>

we have to show the ng-show in ng-pattern

   <span class="alert-error" ng-show="form['QTY' + $index].$error.pattern">
   <span class="alert-error" ng-show="form['QTY' + $index].$error.required">

The difference between == and equals confused me for sometime until I decided to have a closer look at it. Many of them say that for comparing string you should use equals and not ==. Hope in this answer I will be able to say the difference.

The best way to answer this question will be by asking a few questions to yourself. so let's start:

What is the output for the below program:

String mango = "mango";
String mango2 = "mango";
System.out.println(mango != mango2);
System.out.println(mango == mango2);

if you say,

false
true

I will say you are right but why did you say that? and If you say the output is,

true
false

I will say you are wrong but I will still ask you, why you think that is right?

Ok, Let's try to answer this one:

What is the output for the below program:

String mango = "mango";
String mango3 = new String("mango");
System.out.println(mango != mango3);
System.out.println(mango == mango3);

Now If you say,

false
true

I will say you are wrong but why is it wrong now? the correct output for this program is

true
false

Please compare the above program and try to think about it.

Ok. Now this might help (please read this : print the address of object - not possible but still we can use it.)

String mango = "mango";
String mango2 = "mango";
String mango3 = new String("mango");
System.out.println(mango != mango2);
System.out.println(mango == mango2);
System.out.println(mango3 != mango2);
System.out.println(mango3 == mango2);
// mango2 = "mang";
System.out.println(mango+" "+ mango2);
System.out.println(mango != mango2);
System.out.println(mango == mango2);

System.out.println(System.identityHashCode(mango));
System.out.println(System.identityHashCode(mango2));
System.out.println(System.identityHashCode(mango3));

can you just try to think about the output of the last three lines in the code above: for me ideone printed this out (you can check the code here):

false
true
true
false
mango mango
false
true
17225372
17225372
5433634

Oh! Now you see the identityHashCode(mango) is equal to identityHashCode(mango2) But it is not equal to identityHashCode(mango3)

Even though all the string variables - mango, mango2 and mango3 - have the same value, which is "mango", identityHashCode() is still not the same for all.

Now try to uncomment this line // mango2 = "mang"; and run it again this time you will see all three identityHashCode() are different. Hmm that is a helpful hint

we know that if hashcode(x)=N and hashcode(y)=N => x is equal to y

I am not sure how java works internally but I assume this is what happened when I said:

mango = "mango";

java created a string "mango" which was pointed(referenced) by the variable mango something like this

mango ----> "mango"

Now in the next line when I said:

mango2 = "mango";

It actually reused the same string "mango" which looks something like this

mango ----> "mango" <---- mango2

Both mango and mango2 pointing to the same reference Now when I said

mango3 = new String("mango")

It actually created a completely new reference(string) for "mango". which looks something like this,

mango -----> "mango" <------ mango2

mango3 ------> "mango"

and that's why when I put out the values for mango == mango2, it put out true. and when I put out the value for mango3 == mango2, it put out false (even when the values were the same).

and when you uncommented the line // mango2 = "mang"; It actually created a string "mang" which turned our graph like this:

mango ---->"mango"
mango2 ----> "mang"
mango3 -----> "mango"

This is why the identityHashCode is not the same for all.

Hope this helps you guys. Actually, I wanted to generate a test case where == fails and equals() pass. Please feel free to comment and let me know If I am wrong.

For everyone using editors like Komodo Edit (win10) add sys.stdout.flush() to:

def mp_worker((inputs, the_time)):
    print " Process %s\tWaiting %s seconds" % (inputs, the_time)
    time.sleep(int(the_time))
    print " Process %s\tDONE" % inputs
    sys.stdout.flush()

or as first line to:

    if __name__ == '__main__':
       sys.stdout.flush()

This helps to see what goes on during the run of the script; in stead of having to look at the black command line box.

None of the answers worked for me. For some strange reason, when looping through the options, each option returns nothing when text() is called. Instead, I was forced to retrieve the option's label via attr('label')

/**
 * Sort the options of the target select list
 * alphabetically by label. For some reason, when
 * we call detach(), the returned options have no
 * text() and instead we're forced to get the option's
 * label via the 'label' attribute.
 * @param select jQuery selector
 */
function sort_multi_select(select) {
    var options = select.find('option');
    options.detach().sort(function (a, b) {
        var at = $(a).attr('label'), //label, not text()
            bt = $(b).attr('label');
        return at > bt ? 1 : at < bt ? -1 : 0;
    });
    options.appendTo(select);
}

//example
sort_multi_select($('#my_select'));

@Martin Konecny's answer provides the correct answer, but - as he mentions - it only works if the actual script is not invoked through a symlink residing in a different directory.

This answer covers that case: a solution that also works when the script is invoked through a symlink or even a chain of symlinks:

Linux / GNU readlink solution:

If your script needs to run on Linux only or you know that GNU readlink is in the $PATH, use readlink -f, which conveniently resolves a symlink to its ultimate target:

 scriptDir=$(dirname -- "$(readlink -f -- "$BASH_SOURCE")")

^{Note that GNU readlink has 3 related options for resolving a symlink to its ultimate target's full path: -f (--canonicalize), -e (--canonicalize-existing), and -m (--canonicalize-missing) - see man readlink.
Since the target by definition exists in this scenario, any of the 3 options can be used; I've chosen -f here, because it is the most well-known one.}

Multi-(Unix-like-)platform solution (including platforms with a POSIX-only set of utilities):

If your script must run on any platform that:

• has a readlink utility, but lacks the -f option (in the GNU sense of resolving a symlink to its ultimate target) - e.g., macOS.

  • macOS uses an older version of the BSD implementation of readlink; note that recent versions of FreeBSD/PC-BSD do support -f.

• does not even have readlink, but has POSIX-compatible utilities - e.g., HP-UX (thanks, @Charles Duffy).

The following solution, inspired by https://stackoverflow.com/a/1116890/45375, defines helper shell function, rreadlink(), which resolves a given symlink to its ultimate target in a loop - this function is in effect a POSIX-compliant implementation of GNU readlink's -e option, which is similar to the -f option, except that the ultimate target must exist.

Note: The function is a bash function, and is POSIX-compliant only in the sense that only POSIX utilities with POSIX-compliant options are used. For a version of this function that is itself written in POSIX-compliant shell code (for /bin/sh), see here.

• If readlink is available, it is used (without options) - true on most modern platforms.

• Otherwise, the output from ls -l is parsed, which is the only POSIX-compliant way to determine a symlink's target.
  Caveat: this will break if a filename or path contains the literal substring -> - which is unlikely, however.
  (Note that platforms that lack readlink may still provide other, non-POSIX methods for resolving a symlink; e.g., @Charles Duffy mentions HP-UX's find utility supporting the %l format char. with its -printf primary; in the interest of brevity the function does NOT try to detect such cases.)

• An installable utility (script) form of the function below (with additional functionality) can be found as rreadlink in the npm registry; on Linux and macOS, install it with [sudo] npm install -g rreadlink; on other platforms (assuming they have bash), follow the manual installation instructions.

If the argument is a symlink, the ultimate target's canonical path is returned; otherwise, the argument's own canonical path is returned.

I stumbled across this set of css properties which seem to vertically align the text in sized select elements in Firefox:

select
{
    box-sizing: content-box;
    -moz-box-sizing:content-box;
    -webkit-box-sizing:content-box;
}

If anything, though, it pushes the text down even farther in IE8. If I set the box-sizing property back to border-box, it at least doesn't make IE8 any worse (and FF still applies the -moz-box-sizing property). It would be nice to find a solution for IE, but I'm not holding my breath.

Edit: Nix this. It doesn't work after testing. For anyone interested, though, the problem seems to stem from built-in styles in FF's forms.css file affecting input and select elements. The property in question is line-height:normal !important. It cannot be overridden. I've tried. I discovered that if I delete the built-in property in Firebug I get a select element with reasonably vertically-centered text.

another thing you could try is to rename your old jdk folder, lets say its:

C:\Program Files\Java\jdk1.7.0_04

change it to saomething like:

C:\Program Files\Java\xxxjdk1.7.0_04

Now, you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch, and you can chose the right path.

Not the most elegant solution, but it worked for me.

If you want to check if the User clicked on the I'm not a robot checkbox, you can use the .getResponse() function provided by the reCaptcha API.

It will return an empty string in case the User did not validate himself, something like this:

if (grecaptcha.getResponse() == ""){
    alert("You can't proceed!");
} else {
    alert("Thank you");
}

In case the User has validated himself, the response will be a very long string.

More about the API can be found on this page: reCaptcha Javascript API

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

versionCode

A positive integer used as an internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName setting, below. The Android system uses the versionCode value to protect against downgrades by preventing users from installing an APK with a lower versionCode than the version currently installed on their device.

The value is a positive integer so that other apps can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any positive integer you want, however you should make sure that each successive release of your app uses a greater value. You cannot upload an APK to the Play Store with a versionCode you have already used for a previous version.

versionName

A string used as the version number shown to users. This setting can be specified as a raw string or as a reference to a string resource.

The value is a string so that you can describe the app version as a .. string, or as any other type of absolute or relative version identifier. The versionName has no purpose other than to be displayed to users.

There is no such thing like a DateTime without a year!

From what I gather your design is a bit strange:

I would recommend storing a "start" (DateTime including year for the FIRST occurence) and a value which designates how to calculate the next event... this could be for example a TimeSpan or some custom structure esp. since "every year" can mean that the event occurs on a specific date and would not automatically be the same as saysing that it occurs in +365 days.

After the event occurs you calculate the next and store that etc.

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

dynamic_cast is known to be inefficient. It traverses up the inheritance hierarchy, and it is the only solution if you have multiple levels of inheritance, and need to check if an object is an instance of any one of the types in its type hierarchy.

But if a more limited form of instanceof that only checks if an object is exactly the type you specify, suffices for your needs, the function below would be a lot more efficient:

template<typename T, typename K>
inline bool isType(const K &k) {
    return typeid(T).hash_code() == typeid(k).hash_code();
}

Here's an example of how you'd invoke the function above:

DerivedA k;
Base *p = &k;

cout << boolalpha << isType<DerivedA>(*p) << endl;  // true
cout << boolalpha << isType<DerivedB>(*p) << endl;  // false

You'd specify template type A (as the type you're checking for), and pass in the object you want to test as the argument (from which template type K would be inferred).

Firefox and other programs allow you to increase and decrease the font size with C-+ and C--. I set up my .emacs so that I have that same ability by adding these lines of code:

(global-set-key [C-kp-add] 'text-scale-increase)

(global-set-key [C-kp-subtract] 'text-scale-decrease)

You can also modify your config/routes.rb file like:

 get 'ajax/:action', to: 'ajax#:action', :defaults => { :format => 'json' }

Which will default the format to json. It is working fine for me in Rails 4.

Or if you want to go even further and you are using namespaces, you can cut down the duplicates:

namespace :api, defaults: {format: 'json'} do
   #your controller routes here ...
end

with the above everything under /api will be formatted as json by default.

Edit: the original answer was misleading, np.sqrt was applied directly to the array, just with a small overhead.

In multidimensional cases where you want to apply a builtin function that operates on a 1d array, numpy.apply_along_axis is a good choice, also for more complex function compositions from numpy and scipy.

Previous misleading statement:

Adding the method:

def along_axis(x):
    return np.apply_along_axis(f, 0, x)

to the perfplot code gives performance results close to np.sqrt.

For Windows I found this working:

Set http = CreateObject("Microsoft.XmlHttp")
http.open "GET", "http://www.mywebservice.com/webmethod.asmx?WSDL", FALSE
http.send ""
WScript.Echo http.responseText

Looks like you're missing the SEPARATOR keyword in the GROUP_CONCAT function.

GROUP_CONCAT(artists.artistname SEPARATOR '----')

The way you've written it, you're concatenating artists.artistname with the '----' string using the default comma separator.

Don't ever put an Exit button on an Android app. Let the OS decide when to kill your Activity. Learn about the Android Activity lifecycle and implement any necessary callbacks.

I had this error and was explicitly setting the blocksize: aesManaged.BlockSize = 128;

Once I removed that, it worked.

Depending on the Tkinter activity, and especially when using Tkinter.after, stopping this activity with destroy() -- even by using protocol(), a button, etc. -- will disturb this activity ("while executing" error) rather than just terminate it. The best solution in almost every case is to use a flag. Here is a simple, silly example of how to use it (although I am certain that most of you don't need it! :)

from Tkinter import *

def close_window():
  global running
  running = False  # turn off while loop
  print( "Window closed")

root = Tk()
root.protocol("WM_DELETE_WINDOW", close_window)
cv = Canvas(root, width=200, height=200)
cv.pack()

running = True;
# This is an endless loop stopped only by setting 'running' to 'False'
while running: 
  for i in range(200): 
    if not running: 
        break
    cv.create_oval(i, i, i+1, i+1)
    root.update() 

This terminates graphics activity nicely. You only need to check running at the right place(s).

Yes, it is used all the time for testing. It is very likely that the testing framework uses .equals() for comparisons such as these.

Below is a link explaining the "string equality mistake". Essentially, strings in Java are objects, and when you compare object equality, typically they are compared based on memory address, and not by content. Because of this, two strings won't occupy the same address, even if their content is identical, so they won't match correctly, even though they look the same when printed.

http://blog.enrii.com/2006/03/15/java-string-equality-common-mistake/

in A you have used a definition of B which is not given until then , that's why the compiler is giving error .

Insert mode has no such command, unfortunately. In VIM, to delete the whole word under the cursor you may type viwd in NORMAL mode. Which means "Visual-block Inner Word Delete". Use an upper case W to include punctuation.

echo $a | grep -bo cat | sed 's/:.*$//'

\b <= this is a word boundary.

Matches at a position that is followed by a word character but not preceded by a word character, or that is preceded by a word character but not followed by a word character.

\w <= stands for "word character". 

It always matches the ASCII characters [A-Za-z0-9_]

Is there anything specific you are trying to match?

The correct answer IMO depends on two things: 1. What is the purpose of the web application you want to write? You only told us that you want to write it fast, but not what you are actually trying to do. Eg. does it need a database? Is it some sort of business app (hint: maybe search for "scaffolding")? ..or a game? ..or are you just experimenting with sthg? 2. What frameworks are you most familiar with right now? What often takes most time is reading docs and figuring out how things (really) work. If you want it done quickly, stick to things you already know well.

private void Form1_Load(object sender, EventArgs e)
    {
        DataTable StudentDataTable = new DataTable("Student");

        //perform this on the Load Event of the form
        private void AddColumns() 
        {
            StudentDataTable.Columns.Add("First_Int_Column", typeof(int));
            StudentDataTable.Columns.Add("Second_String_Column", typeof(String));

            this.dataGridViewDisplay.DataSource = StudentDataTable;
        }
    }

    //Save_Button_Event to save the form field to the table which is then bind to the TableGridView
    private void SaveForm()
        {
            StudentDataTable.Rows.Add(new object[] { textBoxFirst.Text, textBoxSecond.Text});

            dataGridViewDisplay.DataSource = StudentDataTable;
        }

If you code C or C++ language. I think we are lucky because we could use a file to input. It is so convenient and clear. I often do that. This is argument to implement it :

{
freopen("inputfile", "r", stdin);
}

Notice that inputfile must locate at same directory with source code file, r is stand for read.

If your array is not initialized then it contains randoms values and cannot be checked !

To initialize your array with 0 values:

int array[5] = {0};

Then you can check if the value is 0:

array[4] == 0;

When you compare to NULL, it compares to 0 as the NULL is defined as integer value 0 or 0L.

If you have an array of pointers, better use the nullptr value to check:

char* array[5] = {nullptr}; // we defined an array of char*, initialized to nullptr

if (array[4] == nullptr)
    // do something

You could try this via SSH: rm -rf foldernamehere

I recently had this issue (but before that debug over wifi was working fine) and since none of the above answers helped me let me share what I did.

1. Go to developer options
2. Find Select USB configurations and click it
3. Choose MTP (Media Transfer Protocol)

Note: If it's set to this option chose another option such as PTP first then set it to MTP again.

UPDATE:

PTP stands for “Picture Transfer Protocol.” When Android uses this protocol, it appears to the computer as a digital camera.

MTP is actually based on PTP, but adds more features, or “extensions.” PTP works similarly to MTP and is commonly used by digital cameras.

This does not require a HTML entity if you are using a modern encoding (such as UTF-8). And if you're not already, you probably should be.

I ran into this problem as well, and figured out that the problem is in the browser. When you refresh the browser is re-populating the form with the same values as before, ignoring the checked field. If you view source, you'll see the checked value is correct. Or put your cursor in your browser's URL field and hit enter. That will re-load the form from scratch.

I made a script to make the command line cursor move on mouse click :

1. Enable xterm mouse tracking reporting
2. Set readline bindings to consume the escape sequence generated by clicks

It can be found on github

More info on another post

Will work if echo -e "\e[?1000;1006;1015h" # Enable tracking print escape sequences on terminal when clicking with mouse

The following command will list all users belonging to <your_group_name>, but only those managed by /etc/group database, not LDAP, NIS, etc. It also works for secondary groups only, it won't list users who have that group set as primary since the primary group is stored as GID (numeric group ID) in the file /etc/passwd.

here's a in-space rotate method, by java, only for square. for non-square 2d array, you will have to create new array anyway.

private void rotateInSpace(int[][] arr) {
    int z = arr.length;
    for (int i = 0; i < z / 2; i++) {
        for (int j = 0; j < (z / 2 + z % 2); j++) {
            int x = i, y = j;
            int temp = arr[x][y];
            for (int k = 0; k < 4; k++) {
                int temptemp = arr[y][z - x - 1];
                arr[y][z - x - 1] = temp;
                temp = temptemp;

                int tempX = y;
                y = z - x - 1;
                x = tempX;
            }
        }
    }
}

code to rotate any size 2d array by creating new array:

private int[][] rotate(int[][] arr) {
    int width = arr[0].length;
    int depth = arr.length;
    int[][] re = new int[width][depth];
    for (int i = 0; i < depth; i++) {
        for (int j = 0; j < width; j++) {
            re[j][depth - i - 1] = arr[i][j];
        }
    }
    return re;
}

This is answered in some of the answers to Can't find how to use HttpContent as well as in this blog post.

In summary, you can't directly set up an instance of HttpContent because it is an abstract class. You need to use one the classes derived from it depending on your need. Most likely StringContent, which lets you set the string value of the response, the encoding, and the media type in the constructor. See: http://msdn.microsoft.com/en-us/library/system.net.http.stringcontent.aspx

here's the best of both worlds.

I also "like" underscores, besides all your positive points about them, there is also a certain old-school style to them.

So what I do is use underscores and simply add a small rewrite rule to your Apache's .htaccess file to re-write all underscores to hyphens.

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

I use this function to convert string to tuple

import ast

def parse_tuple(string):
    try:
        s = ast.literal_eval(str(string))
        if type(s) == tuple:
            return s
        return
    except:
        return

Usage

parse_tuple('("A","B","C",)')  # Result: ('A', 'B', 'C')

In your case, you do

value = parse_tuple("('%s',)" % a)

NP stands for Non-deterministic Polynomial time.

This means that the problem can be solved in Polynomial time using a Non-deterministic Turing machine (like a regular Turing machine but also including a non-deterministic "choice" function). Basically, a solution has to be testable in poly time. If that's the case, and a known NP problem can be solved using the given problem with modified input (an NP problem can be reduced to the given problem) then the problem is NP complete.

The main thing to take away from an NP-complete problem is that it cannot be solved in polynomial time in any known way. NP-Hard/NP-Complete is a way of showing that certain classes of problems are not solvable in realistic time.

Edit: As others have noted, there are often approximate solutions for NP-Complete problems. In this case, the approximate solution usually gives an approximation bound using special notation which tells us how close the approximation is.

By default, Button in android provides all caps keyword. If you want button text to be in lower case or mixed case you can disable textAllCaps flag using android:textAllCaps="false"

 $(document).ready(function () {
    $('.dates li a').click(function (e) {

        $('.dates li a').removeClass('active');

        var $parent = $(this);
        if (!$parent.hasClass('active')) {
            $parent.addClass('active');
        }
        e.preventDefault();
    });
});

I tried many ways but this works.

Isn't the platform solution for this implementation to use a context menu that shows on a long press?

Is the question author aware of context menus? Stacking up buttons in a listview has performance implications, will clutter your UI and violate the recommended UI design for the platform.

On the flipside; context menus - by nature of not having a passive representation - are not obvious to the end user. Consider documenting the behaviour?

This guide should give you a good start.

http://www.mikeplate.com/2010/01/21/show-a-context-menu-for-long-clicks-in-an-android-listview/

Note that in the Java implementation, the number of bits to shift is mod'd by the size of the source.

For example:

(long) 4 >> 65

equals 2. You might expect shifting the bits to the right 65 times would zero everything out, but it's actually the equivalent of:

(long) 4 >> (65 % 64)

This is true for <<, >>, and >>>. I have not tried it out in other languages.

The regex you're looking for is ^[A-Za-z.\s_-]+$

• ^ asserts that the regular expression must match at the beginning of the subject
• [] is a character class - any character that matches inside this expression is allowed
• A-Z allows a range of uppercase characters
• a-z allows a range of lowercase characters
• . matches a period rather than a range of characters
• \s matches whitespace (spaces and tabs)
• _ matches an underscore
• - matches a dash (hyphen); we have it as the last character in the character class so it doesn't get interpreted as being part of a character range. We could also escape it (\-) instead and put it anywhere in the character class, but that's less clear
• + asserts that the preceding expression (in our case, the character class) must match one or more times
• $ Finally, this asserts that we're now at the end of the subject

When you're testing regular expressions, you'll likely find a tool like regexpal helpful. This allows you to see your regular expression match (or fail to match) your sample data in real time as you write it.

Here is the unpowerful official command:

npm view <PACKAGE> dependencies

It prints only the direct dependencies, not the whole tree.

The most simplist thing you can try is:

df=df[[ 'Mid',   'Upper',   'Lower', 'Net'  , 'Zsore']]

It exists a property called XmlElementAttribute.IsNullable

If the IsNullable property is set to true, the xsi:nil attribute is generated for class members that have been set to a null reference.

The following example shows a field with the XmlElementAttribute applied to it, and the IsNullable property set to false.

public class MyClass
{
   [XmlElement(IsNullable = false)]
   public string Group;
}

You can have a look to other XmlElementAttribute for changing names in serialization etc.

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

It helps not to focus on the strong or weak part of the discussion. Instead focus on the cycle part.

A retain cycle is a loop that happens when Object A retains Object B, and Object B retains Object A. In that situation, if either object is released:

• Object A won't be deallocated because Object B holds a reference to it.
• But Object B won't ever be deallocated as long as Object A has a reference to it.
• But Object A will never be deallocated because Object B holds a reference to it.
• ad infinitum

Thus, those two objects will just hang around in memory for the life of the program even though they should, if everything were working properly, be deallocated.

So, what we're worried about is retain cycles, and there's nothing about blocks in and of themselves that create these cycles. This isn't a problem, for example:

[myArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop){
   [self doSomethingWithObject:obj];
}];

The block retains self, but self doesn't retain the block. If one or the other is released, no cycle is created and everything gets deallocated as it should.

Where you get into trouble is something like:

//In the interface:
@property (strong) void(^myBlock)(id obj, NSUInteger idx, BOOL *stop);

//In the implementation:
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
  [self doSomethingWithObj:obj];     
}];

Now, your object (self) has an explicit strong reference to the block. And the block has an implicit strong reference to self. That's a cycle, and now neither object will be deallocated properly.

Because, in a situation like this, self by definition already has a strong reference to the block, it's usually easiest to resolve by making an explicitly weak reference to self for the block to use:

__weak MyObject *weakSelf = self;
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
  [weakSelf doSomethingWithObj:obj];     
}];

But this should not be the default pattern you follow when dealing with blocks that call self! This should only be used to break what would otherwise be a retain cycle between self and the block. If you were to adopt this pattern everywhere, you'd run the risk of passing a block to something that got executed after self was deallocated.

//SUSPICIOUS EXAMPLE:
__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  //By the time this gets called, "weakSelf" might be nil because it's not retained!
  [weakSelf doSomething];
}];
